First, finger board production process operating procedures
1. Loading and unloading kiln: (1) Employees must obey the designated arrangement of the inspection scale and management personnel and stack them reasonably to ensure that the material grade is clear and the incoming material unit is clear. (2) When swinging the kiln, the bark material, rotten material or severely thin material should be singled out in time for stacking. It is forbidden to flow into the workshop, and the qualified rate of the plate reaches more than 97%. (3) The size of each kiln is clear, and the position is reasonable and conducive to drying. It is easy to separate the materials without mixing the materials. In addition to the bottom of the two meters of long products, the other shall be determined and then put the kiln. (4) It is forbidden to use the crane equipment when the crane has not been tested. (5) The use of the crane is strictly prohibited at the bottom of the crane.
2. Drying: (1) Drying staff accurately counts the quantity handed over by the inspection department. During the process from loading and unloading to the kiln car entering the workshop, timely record tracking is performed to ensure that the material registration is not heavy. (2) In the drying process, first preheat for 4-6 hours, dry for 22-24 hours, and control the temperature between 45-55, then increase the baking rate by 2-4 degrees per day, 7CM wood The maximum can only reach 65 degrees, other wood can be properly increased by 7-10 degrees, when the wood moisture content is basically below 10 degrees, you can reach the kiln standards. (3) Inadequate fan or fan failure or damage should be reported in time to ensure the normal operation of the baking room machinery and equipment. (4) Drying employees should promptly ensure that the kiln car is ready to enter and strive to increase the drying level.
3. Boiler: (1) Correctly operate according to the safety operation regulations formulated by the quality supervision department and perform effective maintenance on the boiler in time. (2) Find out hidden dangers and immediately stop and report to the competent personnel. (3) In production, ensure the steam supply in the workshop. (4) The shavings and rubbish in the boiler room should be cleaned and tidy at any time, and often sprinkle water to maintain a certain surface humidity to prevent accidents.
4. Rough cuts: (1) Wood entering the workshop must check whether the wood reaches the required moisture, and confirm whether the moisture content reaches the standard (normally 10-14%) before cutting. (2) The shortest length of long products is not less than 30CM, and the longest is less than 60CM. (3) When loading or cutting, it was found that rotten plates, bark materials, cracked plates, and non-specified materials were selected for separate treatment. (4) Timely guarantee of production of rough planer, no phenomenon of rough planer stand-off and standby. (5) Ensure that the material pick-up rate is over 99%.
5. Refer to the rough planer: (1) Check whether the parts or tools of the equipment are normal before starting the machine. Lubricate the parts that need to be refueled. (2) In the process of adjusting machine, proper adjustment of dimensions shall be made according to the width, width and thickness of the sheet material. The overall tool planing quantity must be uniform. Before the batch production, the first item inspection must meet the requirements before production. (3) As much as possible to save materials, reduce the amount of planing, in the width of the planed amount of more than 30mm, the thickness adjusted to less than 1.8mm, must be confirmed by the site management personnel before operation. (4) Ordinary materials must be selected from rotten plates, bark materials, deformed materials, cracked plates, large or thin plates, and single-sided non-segmented materials must also have no scars on one surface. (5) on the material stacking, double-sided planing plate, single-side planed plate, double-sided planing plate, slip-side plates should be stacked separately; end should not be tidy should be the same; tree bark and rotten plate , Deformation materials are piled up separately; slipping one plate that has slipped less than another will be piled up separately and then beside the next time, the slippery side can only slip below 2mm at a time. Thin side can be slippery surface, a sliding surface can be adjusted below 8mm. If you can't slip, you can stack it separately. (6) In the process of planing, there is a phenomenon that the tool is notched or the tool is blunt. (7) The qualified rate of finger-joint plate sorting should be more than 99%. The width, width, thickness and size should be strictly distinguished and clearly stacked at the designated position.
6. Comb teeth: (1) Routinely check the equipment before starting up to ensure that the equipment can be turned on without exception. (2) According to the plate size in a timely manner to adjust the machine tools, so that each bracket plate width measurement, different sizes should be adjusted immediately, the plate and plate finger joints can not appear high and low errors and loose tight phenomenon. (3) For the large number of heads caused by the previous process, the phenomenon of many bark and bad materials should be returned to the previous process for rework, and plates that do not meet the quality must not be allowed to flow into the next process. (4) The countertops should be kept clean at all times to ensure that the material to be combed is in a vertical state at right angles. (5) Comb-blade end saw blade should be adjusted to just trim the end of the head, it can not be left long to cause waste. (6) Unmatched comb cutters must not be mixed and used to produce product quality problems due to inconsistent lengths of caries. (7) If there are obvious burrs or knife marks on the position of the comb teeth, it will directly affect the quality of the product. (8) Ensure that the next lane of the lower finger is flat and tight on both sides.
7. Finger-joint: (1) When commuting, it is necessary to remove the glue and sawdust on the machine table in time to maintain the health of the machine and ensure the quality of finger joints. (2) When gluing, it must be evenly in place. No sand or wood chips or other debris may be caught. (3) In the process of finger-jointing, there is a planed plate, and the unconnected side has to be faced upwards. If a broken plate, a bark, a large or small, severely deformed, cracked plate is found Timely picking up and returning to the previous process for rework. (4) The length of the pointed strip is regularly measured and corrected. The finger length is controlled between 2.46-2.47 meters. (5) The number of employees such as rough planers and combs should be accurately registered every day to ensure that the quantity is not large, not heavy, and that there is no leakage. (6) After each pallet is completed, it must be marked on every pallet so as to track the production of the product.
8. Fixtures: (1) According to the specification and size of the finger strips, distinguish the fingerboard grades to avoid the different specifications mixed together. (2) Before brushing, it is found that rotten finger bars, bark materials, short pieces or misaligned materials are to be picked up and returned to the previous process. (3) Glue must be properly blended and the glue should be evenly applied. No sand or wood chips or other debris should be caught. It is advisable to apply a small amount of glue when sizing. (4) The splices to be spelled should be flush with one end, and the better side and the non-knotted side should face upwards. (5) The jigs should be close to the finger bars to ensure that the puzzles are tight and flat. (6) When sawing, both ends should be in close contact with each other. It is found that the phenomenon of bevel edge, rotten plate, and bark material should be handled in time. (7) For finger-joined panels that have already been assembled, different grades of products should be stacked separately and the product identification must be carefully performed.
9. Saw: (1) Before operation, first check the sharpness of the saw blade. If the saw blade is unfavorable, the saw blade must be replaced. The end should be smooth to see the annual ring profile. Do not operate the rough end of the product. (2) In the course of operation, it was found that there were cracked plates and short finger plates, and the sawing edge should not be returned to the previous process for rework. If there is any illegal operation, the operating staff will repair it.
10. Sanding: (1) During operation, adjust the key points on the sand belt to start the machine. The sand belt is fully adjusted before starting the sanding. (2) Sanding should be carried out according to the different thicknesses of the products, and the thickness of sanding should be strictly controlled. In principle, the better side is less sand and the poorer side is more sand. (3) In the last sanding of sand, sand quality must be observed in the quality of the surface of the product, and the level of the product must be controlled. The thickness is the principle of every five.
11. Repair packaging: (1) When repairing, fix all the defects of the fingerboard with plastic clay, including finger joints, joint seams, defects caused by thin materials, etc., with small bark, pests, Cracked product, dig open with sawdust and 502 glue repair. (2) Large defects, rotten plates, cracks, knots, knots, bark boards, insect standing boards, short finger boards, etc. are picked out separately. (3) When repairing the package, tiny gaps, defects, and pinholes must be filled with 502 glue to ensure that the specifications of each product are uniform, and the ends and plates are flush and seamless, and the quality meets the eligibility criteria.
