specific Embodiment approach 1

[0024] Specific implementation mode one: combine figure 1 figure 2 , image 3 and Figure 4 To illustrate this embodiment, a wood-plastic composite material production unit of this embodiment includes a wood-plastic composite material extruder 1, and the wood-plastic composite material production unit also includes an extrusion die 2, a cooling guide roll 3, a heating calender roll 4, Active cooling sizing roll 5, multiple passive cooling sizing rolls 6, multiple cooling water spray devices 7 and transmission assembly 8, extrusion die 2 is installed at the output end of wood-plastic composite material extruder 1, cooling guide roll 3 and The heating calender rolls 4 are sequentially arranged at the exit end of the extrusion die 2 from left to right, the structure of the cooling guide roll 3 and the heating calender roll 4 is the same, and the transmission assembly 8 is connected with the active cooling sizing roll 5 and the passive cooling sizing roll 6. A cooling water sp...

specific Embodiment approach 2

[0025] Specific implementation mode two: combination figure 1 and figure 2 To illustrate this embodiment, the extrusion die 2 of this embodiment includes a discharge port module 2-1, a sealing pad bead 2-2, a sealing pad 2-3 and a replaceable cushion block 2-4, and the discharge port module 2-1 There is a tapered hole 2-5 in the middle of the center, and the gasket 2-3 is installed between the outlet end of the outlet module 2-1 and the cooling guide roller 3 through the gasket bead 2-2, and the replaceable pad 2-4 is installed At the outlet of outlet module 2-1. With such an arrangement, by replacing the replaceable pads with different thicknesses and widths, the discharge state of the discharge port can be changed to form discharges with different thicknesses and widths, so as to meet the needs of products with different widths and thicknesses. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0026] Specific implementation mode three: combination figure 2 To describe this embodiment, the outer end surface of the outlet of the outlet module 2-1 of this embodiment is provided with a concave arc surface. Such setting facilitates the engagement with the cooling guide roller 3 . Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

A wood-plastic composite material production unit relates to a composite material production unit. The present invention aims to solve the disadvantages of difficulty in controlling the foaming of polyolefin wood-plastic composite foamed boards in a mold and difficulty in molding after ejection in the existing production process of wood-plastic composite materials. The extrusion die (2) of the present invention is installed on the output end of the wood-plastic composite extruder (1), the extrusion die (2), the cooling guide roll (3), the heating calender roll (4), and the active cooling shaping roll (5) and a plurality of passive cooling and shaping rolls (6) are installed sequentially from left to right, and the transmission assembly (8) connects the active cooling and shaping roll (5) and the passive cooling and shaping roll (6), and two adjacent cooling and shaping rolls ( 6) is respectively provided with a cooling water spraying device (7) above and below. The invention is used for the production of wood-plastic composite materials.

Description

technical field [0001] The invention relates to a production unit, in particular to a wood-plastic composite material production unit. Background technique [0002] As a green and environmentally friendly composite material, wood-plastic composite material has developed rapidly in the world in recent years and is widely used in interior decoration and outdoor gardens. However, due to its high density and low mechanical strength, it is limited in high value-added applications. field applications. Foaming treatment of wood-plastic composites is an effective method to reduce density. The foaming technology of polyolefin is relatively mature, but due to the high content of wood fiber filling in wood-plastic composite materials, its foaming characteristics become complicated and difficult to control. At present, the wood-plastic composite materials with main matrices such as polyethylene and polypropylene The foaming process is still in the exploratory stage. The existing foam...
