Hollow extrusion integrated plastic clamping plate, and production process and equipment thereof

Abstract

The invention discloses a hollow extrusion integrated plastic clamping plate, and a production process and equipment thereof. The hollow extrusion integrated plastic clamping plate comprises a lower supporting plate, supporting seats, support bars, upper support bars, straight slots, side slots, interval slots and hollowed-out slots. The production process of the hollow extrusion integrated plastic clamping plate comprises the following technological steps of feeding, extrusion, hollow forming, slot forming, cooling setting and cutting. The production equipment of the hollow extrusion integrated plastic clamping plate comprises an extruder, a mold, a die cutting machine, a cooling setting machine, a first conveyor belt, a cutter and a second conveyor belt. The hollow extrusion integrated plastic clamping plate can flexibly adapt to the hollow rato according to the bearing requirements, and materials are saved. Various types of different materials can be adopted to be mixed for molding.The hollow extrusion integrated plastic clamping plate is flexible in use and high in universality. The equipment and the mold are low in cost, flexible in manufacturing, applicable to products on different occasions and high in production efficiency.

Description

technical field [0001] The invention relates to the field of pallets, in particular to a hollow extruded integrated plastic pallet and its production process and equipment. Background technique [0002] Pallets are considered to be one of the two key innovations in the logistics industry in the 20th century. As important loading, unloading, storage and transportation equipment in the logistics operation process, pallets play a huge role in modern logistics when used together with forklifts; Applied in the fields of production, transportation, warehousing and distribution, pallet operation is an effective means to rapidly improve handling efficiency and order the flow of materials, and it plays a huge role in reducing production costs and improving production efficiency. According to material classification, commonly used pallets include wooden flat pallets, steel flat pallets, plastic flat pallets, composite material flat pallets and paper pallets, among which traditional wo...

AI Technical Summary

Problems solved by technology

[0003] At present, although the number of pallets in my country is small, it is increasing at an average annual rate of 20 million pieces, and more than 85% of them are wooden pallets, and wooden pallets have the following defects: 1. Wood is susceptible to moisture, mold, and insects , and cannot be cleaned; in addition, the problems of sawdust shedding on the surface and corrosion of screws cannot be overcome

2. Since wood is a natural material, its quality is affected by many aspects such as regional climate. Even if the same batch of raw materials is used, it is difficult to achieve uniform standards in terms of dryness, humidity, and wind cracking.

3. The service life of wooden pallets is short, and there is no residual value after use, and the disposal of its waste will also incur a certain cost

4. Also due to hygienic reasons mainly caused by longhorn beetles, the United States and the European Union have successively issued bans on wooden pallets for export to China since 1998. Wooden pallets must be fumigated before they can be exported; the time and cost required for fumigation It usually takes 48 hours if they are relatively large, and the cost is about 20% of the cost, and the chemicals used for fumigation, such as potassium bromide alcohol, are harmful agents, and the validity period of fumigation is short, which also causes troubles for export enterprises; Pallets need to be removed or destroyed by the carrier; this greatly affects the application of single-use wooden pallets

5. The demand for wood for wooden pallets has caused huge consumption or even destruction of forest resources; with the increasing awareness of social environmental protection, the Chinese government has banned deforestation, so the cost of wooden pallets has risen sharply

This method is also the mainstream method commonly used in the world, but there are defects in this kind of injection molding, which affect and restrict the large-scale promotion of plastic pallets, mainly as follows: 1. The investment threshold is high, and the 3000T injection molding machine together with ancillary facilities exceeds 6 million yuan / Taiwan, and there are high requirements for the factory building, which is difficult for ordinary enterprises to bear

2. The mold structure is complex, bulky, and costly. A pair of molds weighs 10-20 tons and costs more than 500,000 yuan. The operation of the upper and lower molds during injection molding is time-consuming and laborious

3. The production efficiency is low, only one can be produced at a time, the cycle is more than 3 minutes, and the output is low

4. Large material consumption and high cost
