Description

Technical Field

[0001] The invention relates to the technical field of wood plastic product processing, in particular to a wood plastic product surface conditioning machine. Background Art

[0002] Wood-plastic composite board is a high-tech, green and environmentally friendly new decorative material mainly based on wood, with the addition of thermoplastic polymer materials and processing aids. The above materials are mixed evenly and then heated and extruded by mold equipment. It has the performance and characteristics of both wood and plastic and is a new composite material that can replace wood and plastic.

[0003] When the current wood-plastic board is produced, the production process of extrusion molding is mostly used. However, when the wood-plastic board is cooled after being formed, the wood-plastic board structure often shrinks to a certain extent when cooled, which causes the surface of the produced board to be uneven, seriously affecting the quality of the board. At this time, the technical personnel found that the surface of the wood-plastic board can be heat-treated again to regulate the quality of the wood-plastic board. In the prior art, multiple strip-shaped electric heating wires are often used to heat the surface of the board, that is, multiple electric heating wires are arranged in the same horizontal plane and parallel to each other, and the board is transported to the bottom of the electric heating wire after power is turned on for heating. However, since the long strip-shaped electric heating wire is easily deformed after being suspended, it is difficult to keep it in a straight state, so the surface of the board is heated unevenly. On the other hand, the length of each electric heating wire in the prior art is relatively large. When multiple electric heating wires arranged in parallel to each other heat the board at the same time, since the wood-plastic board is continuously heated during the entire process, it is easy to cause the surface of the wood-plastic board to be damaged by high-temperature heating.

[0004] Therefore, a new technical solution is provided to solve the above technical problems. Summary of the invention

[0031] Since it is necessary to drive the roller body to move up and down and to press the roller body against the surface of the wood-plastic board, in a preferred embodiment, the vertical transmission structure 12 is a transmission screw structure, and the first base 131 is connected to the transmission screw body 121 in the transmission screw structure.

[0032] To further increase the safety of use, an insulating structure is connected inside the second frame 20, and the insulating structure includes a metal connection part 207, a cross arm 208 and a plurality of insulators 209. The connecting screws (not shown in the figure) at the upper and lower ends of the insulator 209 are respectively connected to the metal connection part 207 and the cross arm 208, and the metal connection part 207 is connected to the inner wall of the second frame 20. In practical applications, the insulator 209 structure is commonly found on high-voltage power poles. Therefore, the working principle and use method of the insulator 209 are both prior art and will not be described in detail herein. When the insulator 209 is used in the present invention, its main function is to prevent leakage on the surface of the second frame 20.

[0033] Working principle of the present invention: the wood-plastic board passes between the two first limiting rollers 102 and is sent to the surface of the conveyor belt body, and the pressure roller body is pressed down to prevent the board from deviating during the conveying process. When the wood-plastic board is conveyed to the bottom of the second frame 20, the head of the board is first supported by the first roller 205 (the first roller 205 is close to the left end of the second frame 20), and the board is continuously conveyed toward the right end of the second frame 20. At the same time, the heating structure above it heats it. When the wood-plastic board is supported by the first roller 205 and the second roller 206 at the same time, the surface of the wood-plastic board is completely heated, and the wood-plastic board can be taken out from the bottom of the second frame 20. In the present invention, taking the first heating structure 21 as an example, the long strip heating wire is spirally connected to a plurality of connecting plates, which can ensure that the heating wire is evenly distributed on the connecting plates, and the length of the heating wire between two adjacent connecting plates is small, which makes it easy to make the shapes of the heating wires arranged in multiple sections more consistent, thereby facilitating uniform heating of the surface of the board, and an installation spacing is provided between the plurality of heating structures with heating wires, so that the surface of the wood-plastic board can be heated in sections to ensure product quality.

[0034] In actual applications, due to the four connecting plates on the shaft rod, the heating wire is set in sections, and only part of the heating wire can heat the surface of the board. The part of the heating wire far away from the surface of the wood-plastic board cannot effectively heat the wood-plastic board, resulting in a waste of heat energy. On the other hand, since the heating structure is fixed, it is difficult to effectively ensure that the hot air flow can directly hit the surface of the wood-plastic board, and it is difficult to ensure the heating efficiency. To solve the above technical problems, in this embodiment, the first shaft rod 211 is connected to the second frame 20 through a fifth bearing structure (not marked in the figure), the two ends of the first shaft rod 211 are protrudingly arranged on both sides of the second frame 20, the two ends of the first shaft rod 211 are respectively sleeved with first gears 2111, and a second gear 2112 is installed at one end of the first shaft rod 211; the second shaft rod 221 is connected to the second frame 20 through a sixth bearing structure (not marked in the figure), the two ends of the second shaft rod 221 are protrudingly arranged on both sides of the second frame 20, and the two ends of the second shaft rod 221 are respectively sleeved with third gears 2211; it also includes a second drive motor 23, a fourth gear 231 is connected to the motor shaft of the second drive motor 23, the fourth gear 231 is connected to the second gear 2112 through a first chain transmission structure 24, and the first gear 2111 is connected to the third gear 2211 through a second chain transmission structure 25. The motor shaft of the second driving motor 23 rotates to drive the fourth gear 231, and the fourth gear 231 drives the second gear 2112 to rotate through the first chain transmission structure 24. The rotation of the second gear 2112 drives the first shaft rod 211 to rotate, and the first shaft rod 211 rotates to drive the first gear 2111 thereon to rotate, thereby driving the third gear 2211 to rotate, and finally the second shaft rod 221 and the first shaft rod 211 are linked to drive the connecting plates on the two shaft rods to rotate in a preset direction, so that the hot air flow can be fanned to the surface of the board, which can increase the heating efficiency of the surface of the wood-plastic board, reduce the waste of heat energy, and make the heating wire far away from the surface of the wood-plastic board close to the surface of the wood-plastic board to effectively utilize the heat energy of the heating wire. It is worth noting that since the heating wire needs to be powered on to heat up, an electric wire is connected to the heating wire (this structure is common knowledge and will not be repeated in this article). Therefore, the heating wire cannot rotate the shaft rod indefinitely when powered on. Therefore, the motor can only be driven to drive the shaft rod to rotate a preset angle to prevent the wire from breaking after being wound. However, the length of the wire can be set to a larger length so that the shaft rod can rotate at a larger angle.

[0035] In this embodiment, the first pile body 201, the second pile body 202, the third pile body 203 and the fourth pile body 204 are all connected to the second frame 20 via a detachable structure. Figure 5As shown, the detachable structure includes a connecting arm 26, an adjusting screw 27 and a first connecting seat 28. The top of the first pile body 201, the top of the second pile body 202, the top of the third pile body 203 and the top of the fourth pile body 204 are all connected to the connecting arm 26. The first connecting seat 28 is connected to the connecting arm 26. The surface of the first connecting seat 28 is provided with an axial hole (not shown in the figure). Two limiting nuts 29 are connected to the adjusting screw 27. One end of the adjusting screw 27 is inserted into the first connecting seat 28. The two limiting nuts 29 are respectively located at the upper and lower ends of the first connecting seat 28. The other end of the adjusting screw 27 is fixedly connected to the second frame 20. This type of structural setting is convenient for disassembly and assembly and shipping of the heating structure, and is convenient for storage. It can also be used to adjust the vertical distance between the second frame 20 and the two rollers below it, and can perform surface heat treatment on wood-plastic panels of different thicknesses.

[0036] In this embodiment, an auxiliary supporting mechanism 3 is also included. The right end of the second frame 20 faces the auxiliary supporting mechanism 3. The auxiliary supporting mechanism 3 includes a plurality of third rollers 31 and a second base 32. The plurality of third rollers 31 are arranged on the second base 32 along the length direction of the second frame 20. The third rollers 31 and the second rollers 206 are parallel to each other and located on the same horizontal plane. The third rollers 31 are installed on the second base 32 through a seventh bearing structure (not shown in the figure); the surface of the third rollers 31 is coated with a heat insulation material layer 33. Further, the heat insulation material layer 33 is a heat insulation cotton material layer.

[0037] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
