The molded pallet heat press is a new type of molded pallet production equipment. The equipment uses hot pressing technology to form the molded parts in one go. The molded pallet heat press meets environmental protection requirements.
Scope of application of molded pallet heat press: waste wood, waste wood chips, sawdust wood chips, shavings, wood chips, large wood chips, logs, burned forest, logs, boards, branches, wood, wood chips and waste pallets, etc., which contain fiber-rich fibers as well Can be used to produce pallets, such as straw, waste kraft paper, bamboo, palm trees, coconut, cork, wheat straw, bagasse and platycodon, etc.
Dingli biomass pallet production line:
1.Preparation of raw materials: According to the requirements of the pallet load-bearing choose wood or straw varieties, chipped into 1-2mm toothpick-like sawdust, strictly control the bark of the impurity content of not more than 5%, after magnetic separation into the dryer, raw materials after drying moisture content ≤ 5%.
2.Mixing: In order to prevent wood chips broken, we should not use high-speed mixing machine, the general use of roller mixing machine, set two spray system, in order to add the two should not be mixed together. Generally use isocyanate and urea -formaldehyde resin mixture, or phenolic resin and melamine resin, the amount of sizing is 3% -8%. After the measurement of wood chips and quantitative adhesive at the same time into the mixing machine, mixed with wood moisture content, should be controlled in the range of 6-8%.
3.Pavement and hot pressing: adopts special equipment, pavement two times, the first for pallet and preload, and then do the plane part of the pallet. Punches fixed in the upper part of the hot press on the activities of the beam, the die is between the hot press and paving machine, placed on the lower press table, a special stripping device. Will be mixed with wood chips in the mold, the pre-pressure, hot pressed until the resin can be fully cured after the mold. First sintered wood chips, quantitative paving into the metal mold in the cold pressing preforming. And then placed in a hot press in the press molding.
4.Side trimming: mainly for the side cutting, that is, to remove the edge of the product flash surplus.
