Problems solved by technology

[0004] The purpose of the present invention is to address some of the deficiencies of the prior art. The present invention pre-rolls and shears the delivered wood flour through the linkage and cooperation of the first shear bar and the second shear bar to reduce the cost of wood flour. Through the mutual cooperation of the second shear bar and the third shear bar, the wood flour, plastic and additives are rolled, sheared and mixed, so that the wood flour is in a state of low agglomeration rate and quickly combines with the plastic and additives. Mixing in the state of being sheared, avoiding the re-agglomeration of wood flour, so as to improve the mixing uniformity of wood flour, plastics and additives, so as to avoid or reduce the performance of wood-plastic panels after molding due to the addition of a large amount of wood flour. problem occurs

Embodiment 1

[0075] Such as Figure 1-9 As shown, the present invention provides a kind of wood-plastic board molding equipment, including a housing 1 and three first shearing bars 20, second shearing rods 20, two shear bar 21 and a third shear bar 22;

[0076] Cooperate with the second shearing bar 21 to rotate the first shearing bar 20 that is sent to the wood flour rolling and shearing and transported to one side of the third shearing bar 22 and is arranged above the second shearing bar 21;

[0077]The third shearing bar 22, which is rotated and matched with the second shearing bar 21, is arranged on both sides of the second shearing bar 21 to carry out mixing, rolling, and shearing of the plastics, additives, and wood flour that has just been rolled and sheared. one of the sides.

[0078] Further, the outer surfaces of the first shear rod 20, the second shear rod 21 and the third shear rod 22 are screw-shaped or gear-shaped structures, and further, the first shear rod 20, the second ...

Embodiment 2

[0088] Such as Figure 1-9 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between this embodiment two and embodiment one is: as one of the embodiments of this case, it also includes a The feeding unit 4 that simultaneously conveys materials between the third shearing bar 22, and the feeding unit 4 is driven by one or both of the first shearing bar 20, the second shearing bar 21 and the third shearing bar 22 connect.

[0089] Further, feed simultaneously between the first shearing bar 20 and the second shearing bar 21, between the second shearing bar 21 and the third shearing bar 22 through the feeding unit 4 simultaneously, can make wood flour and plastics and The auxiliary agent is added and transported in the required ratio, thereby im...

Abstract

The invention relates to the technical field of wood-plastic plate production, in particular to wood-plastic plate forming equipment and a forming process, the forming equipment comprises a shell, a first shearing rod, a second shearing rod and a third shearing rod, and the first shearing rod, the second shearing rod and the third shearing rod are located in the shell, arranged in parallel and rotationally connected through a plurality of first gears; the first shearing rod which is rotationally matched with the second shearing rod to roll and shear the conveyed wood powder and conveys the wood powder to one side of the direction of the third shearing rod is arranged above the second shearing rod; a third shearing rod which is rotationally matched with the second shearing rod to simultaneously mix, roll and shear the conveyed plastic, the assistant and the wood flour which is just rolled and sheared is arranged on one side of the two sides of the second shearing rod; the mixing uniformity of the wood-plastic plate raw materials can be improved, the problem that the performance of the formed wood-plastic plate is greatly reduced due to addition of a large amount of wood flour can be avoided or reduced, and then the forming quality of the wood-plastic plate is improved.

Description

technical field [0001] The invention relates to the technical field of wood-plastic board production, in particular to a wood-plastic board forming equipment and a forming process. Background technique [0002] Wood-plastic board generally refers to a board formed by wood-plastic composite materials. Specifically, it is a new type of green environmental protection material with plastic as the matrix and wood fiber (such as wood, bamboo, peanut shell, coconut shell, flax, straw, etc.) as the reinforcing material. Biomass composite materials have many advantages of both wood and polymer materials, but in order to pursue the ideal wood effect and lower price, a large amount of wood powder will be added in the production process, and the addition of a large amount of wood powder will lead to wood-plastic The performance of the board is severely reduced, which is an important problem faced by wood-plastic production. [0003] The authorized announcement number is a Chinese inven...
