Abstract

A compression mold pallet manufacturing process, including prefabricated operation, compressed operation and subsequent operation. First, place the sawdust and mucilage mixer into the compression mold implement. Forming by compressed in persistence for 7 minutes under 160℃ and 1000Kg. Then, remove the forming pallet, place into mold temperature machine and set the temperature between 120℃~180℃ corresponding to the external environment, keep the heating for 5 minutes and then remove the pallet out from the implement. In this way, besides annihilate the bugs' eggs attached on the sawdust, this process can also enhance the bearing capacity of the forming compressed pallet.

Description

Die Pallet Process

The present invention belongs to a molding pallet manufacturing process; in particular, it relates to a molding pallet manufacturing process, which utilizes lignocellulosic waste materials, crushes them, mixes them with glue (Urea-Formaldehyde resin), pressurizes them, Heating, forming and hardening, to meet the operation requirements of sufficient application for carrying goods and convenient loading and moving such as pushers.

Commonly used pallets are divided into plastic pallets and wooden pallets. Plastic pallets are made of high-density polyethylene, which is not easy to recycle when discarded; If it is made of nailed wood, if it is exported along with the goods, in response to the epidemic prevention regulations of various countries, in order to prevent the invasion of plant diseases and insect pests and foreign species, it must go through heat treatment or smoking procedures, and the wood is easy to absorb moisture and corrode, so it still needs to be pulled out when it is discarded and recycled. Iron nails add to the troubles.

It is known that there are many processed products that use wooden wire and surface materials, including the above-mentioned wooden pallets and plywood. However, although the plywood is processed, it is also used to glue and press the odd-numbered veneer surfaces to enhance its flexibility. However, if it is used on pallets, it is still the same as the nailing process of wooden pallets, and cannot be integrally formed and mass-produced like plastic pallets.

It is known that both plastic pallets and wooden pallets have their inevitable disadvantages in actual use. In view of the demands of environmental protection and recycled products, if we can choose their advantages and ignore their disadvantages, It will be the first choice for the same type of products in the market, so the press molding pallet manufacturing process of the present invention is born accordingly to provide the market with a brand-new pallet product that meets the expectations of many parties.

The present invention especially considers the source and cost of feed materials under technical feasibility, and uses wooden waste materials such as waste wood boards, sawdust, shavings, waste pallets, bagasse, wheat straw, cotton stalks and waste wooden furniture to reduce the cost and cost of feed materials. Environmental cost win-win design system process.

The molding pallet manufacturing process of the present invention is a manufacturing system flow including prefabrication, pressing and follow-up operations, wherein the prefabrication operation is to process wood waste into powder and granular form through chippers, pulverizers and dryers in sequence , and temporarily stored in the customized silo to a certain amount, then put the customized material on the glue mixing platform, continue to inject 15% glue (Urea-Formaldehyde resin) at the weight ratio of the customized material for stirring, and then mix the The finished sawdust and glue mixture is gradually and quantitatively input into the molding machine.

The molding pallet manufacturing process of the present invention is a manufacturing system process including prefabrication, pressing and follow-up operations. The pressing operation is to mix the quantitatively input wood chips and glue in the molding machine through 160 degrees Celsius and 1000 degrees Celsius. The pressure of kilogram and last 7 minutes is compression molding.

The molding pallet manufacturing process of the present invention is a manufacturing system process including prefabrication, pressing and follow-up operations. Room temperature environment, and set the temperature between 120 degrees Celsius and 180 degrees Celsius and continue for 5 minutes to increase the hardness of the fixed type, and finally complete the removal.

The effect of the present invention can provide a wooden pallet product that completely eliminates insect eggs, plant diseases and insect pests, and can be provided in the market as an environmentally friendly recycled product that is durable, usable and safe to use.

[Figure 1] is a schematic diagram of the basic structure of conventional wooden pallet products.

〔Fig. 2〕 is a flow chart of a molding pallet manufacturing process system according to the present invention.

Pallets are short-term mooring pallets during the circulation of goods, just like the rest inn for travelers before they reach their destination, they need a safe place to rest. Therefore, the pallet is the mooring tool on which the goods are placed, but especially in response to the pusher, etc., in order to improve the work efficiency of handling a large number of goods, the necessary structure for fast, stable and safe consignment is specially designed, please refer to the figure 1. It is clear that there is a slot channel 13 reserved between the top surface 11 of the wooden pallet 10 and the tripod 12, so as to facilitate the horizontal insertion of double L-shaped pins into the two slot channels 13 on one side at the same time. Inside, move the original placement position to a new place along with the stacked packaged goods (not shown) on it with a stable vertical support wooden pallet 10 .

The basic structure of the press-molded pallet product of the present invention must be the same with the top surface, tripod and slot channel, but the manufacturing process involves the use of recycled wood waste materials for processing, mixing with glue, integral molding and reinforcement and hardening through the press mold. Therefore, it solves the problems of production cost, efficiency, environmental protection and epidemic prevention at the same time.

The molded pallets of the present invention can be designed to bear different loads according to the needs. In addition to replacing light-weight paper pallets and medium- and high-weight plastic pallets and wooden pallets, they can also be used for load-bearing Frozen fresh food or high-temperature products without leaking possible volatile gas from the pallet material is because the pallet has undergone high-temperature and high-pressure processes, so that the powdered wood and glue will only become more carbonized and hardened according to their original nature.

Please refer to Fig. 2, the molded pallet manufacturing process 30 of the present invention includes prefabrication operations 50. The manufacturing system flow of the pressing operation 70 and the follow-up operation 90, wherein the pre-production operation 50 is to process the wood waste 51 into powder and granular form 55 through the chipper 52, the pulverizer 53 and the dryer 54 in sequence, and temporarily store them After the customized silo 56 reaches a certain amount, put the customized material on the glue mixing platform 57, continue to inject 15% glue (Urea-Formaldehyde resin) in the weight ratio of the customized material and stir 58, and then complete this The sawdust and glue mixture 59 is gradually and quantitatively input into the molding machine 60; among them, the pressing operation 70 is to put the quantitatively input wood chips and glue mixture 59 in the molding machine 60, through 160 degrees Celsius, 1000 kg of pressure and Lasting for 7 minutes is pressing molding 61; the follow-up operation 90 is to take out the molded pallet 62 from the molding machine and put it into the mold temperature controller 63, but in accordance with the external room temperature environment, the temperature is 120 degrees Celsius to 180 degrees Celsius. After setting the temperature between them and continuing for 5 minutes to add a fixed hardness of 64, finally complete the removal of 65.
