Description

Technical Field

[0001] The present invention relates to the technical field of PVC wood-plastic board processing, and particularly relates to a surface treatment device for PVC wood-plastic boards. Background Art

[0002] The processing of PVC wood-plastic boards is a process in which PVC resin and wood fibers (or wood powder) are mixed in a certain proportion, and auxiliaries such as foaming agents, plasticizers, and pigments may be added, and then processed into shape through high temperature and high pressure. This process usually includes steps such as mixing, heating and melting, extrusion or injection molding, and cooling and solidification, and finally produces boards with characteristics such as anti-corrosion, moisture-proof, and insect-proof.

[0003] During the processing of PVC wood-plastic boards, it is necessary to emboss the surface of the PVC wood-plastic boards through an embossing roller. If different patterns need to be embossed, the embossing roller needs to be disassembled and replaced. The disassembly process of the embossing roller involves multiple steps. First, it is necessary to ensure the safety of the working environment and use appropriate tools, such as wrenches and sockets, to loosen and remove the nuts and bolts fixing the embossing roller. Then, use a crane or sling to carefully lift and move the embossing roller while protecting the pipes and components connected to it. During the disassembly process, it is necessary to follow the manufacturer's instructions to ensure disassembly in sequence and avoid damaging the embossing roller and other components. Finally, install the required embossing roller.

[0004] The disassembly process of the embossing roller involves multiple key steps, and since the embossing roller is often heavy, auxiliary tools such as cranes or slings are required during disassembly, and careful operation is needed to avoid damaging the embossing roller and the equipment components around it. The disassembly process is relatively cumbersome and not convenient for replacing embossing rollers with different textures. Summary of the Invention

[0010] As a further solution of the present invention: The limiting component includes a U-shaped limiting plate slidably fitted at the position where the support frame is movably connected to the first hydraulic telescopic rod.

[0011] As a further solution of the present invention: A rotating assembly is slidably sleeved at one end of each of the support rods away from the limit post.

[0016] The beneficial effects of the present invention:

[0017] 1. In the present invention, during disassembly, the third hydraulic telescopic rod drives the fitting block to support the support rod at a similar position. By positioning this group of support rods, the positioning of the limit post is realized. Then, the U-shaped limit plate slidably sleeved on the upper end of the first hydraulic telescopic rod is removed. Then, the bolts on the first clamping plate and the first connection plate are disassembled. The first hydraulic telescopic rod is pushed, so that the first hydraulic telescopic rod drives the first connection plate to move away from the matching support rod. Then, the docking sleeve near the threaded limit cylinder is removed from one end of the support rod. The threaded limit cylinder is rotated, so that the threaded limit cylinder is disengaged from the support rod, thereby unlocking the limit ring plate. The embossing sleeve is pushed to make it disengage from the limit post and the support rod until it leaves the support rod, thus realizing the removal of the embossing sleeve. Then, a suitable embossing sleeve is reinstalled on the limit post, and the threaded limit cylinder, the first clamping plate, and the U-shaped limit plate are reset in sequence, thereby realizing the replacement of the embossing sleeve. The disassembly process is simple and the installation is convenient throughout the process. There is no need for auxiliary equipment such as a crane or a sling, which improves the disassembly efficiency.

[0018] 2. In the present invention, when the surface of the VC wood-plastic board to be embossed is an inclined board surface, the distance between both ends of the limiting column and the embossing platform can be adjusted by the first hydraulic telescopic rod and the second hydraulic telescopic rod. At this time, the first connecting disk rotates relative to the first mounting disk, and the second connecting disk rotates relative to the second mounting disk, so as to change the angle of the limiting column, thereby adapting to the inclined surface of the VC wood-plastic board. When the angle of the limiting column changes, the positions of the support rods on both sides of the limiting column in the corresponding inner sleeves also change. At this time, the spring in the inner sleeve will push the pressure plate to move, and the pressure plate will squeeze the corresponding support rods, so as to ensure that the limiting column can perform a stable embossing operation, expanding the scope of application.

The distance between the other end of the limit post 901 and the embossing platform 1 can be adjusted by the second hydraulic telescopic rod 701.

[0033] A rotating assembly is slidably sleeved at one end of each group of support rods 902 away from the limit post 901. Each group of rotating assemblies includes a docking sleeve 905.

The relative position of the support rod 902 is maintained by the spring 907 and the pressure plate 908.

[0034] The support driving mechanism 3 includes a motor 301 fixedly connected to one side of the embossing platform 1. The output end of the motor 301 is fixedly connected with a support roller 302. The support roller 302 is rotatably connected to the embossing platform 1 and is located directly below the embossing sleeve 904.

[0035] Working principle of the present invention: During use, place the PVC wood-plastic board on the front conveying assembly 11, and heat the surface of the PVC wood-plastic board through the heating assembly 2 to reduce the surface hardness, thereby facilitating the embossing process. When the PVC wood-plastic board is transported between the support roller 302 and the embossing sleeve 904, the motor 301 drives the support roller 302 to rotate. The support roller 302 drives the PVC wood-plastic board to move, and the PVC wood-plastic board drives the embossing sleeve 904 to rotate along the upper surface of the PVC wood-plastic board, thereby realizing the embossing operation on the surface of the PVC wood-plastic board. After the operation of the PVC wood-plastic board is completed, the rear conveying assembly 4 drives the PVC wood-plastic board away from the support roller 302. An intelligent oil distribution tank 8 is provided on the support frame 5. The intelligent oil distribution tank 8 is located directly above the embossing mechanism 9 and is used to replenish lubricating oil on the surface of the embossing sleeve 904;

[0036] When the surface of the PVC wood-plastic board to be embossed is an inclined board surface, the distance between one end of the limit post 901 and the embossing platform 1 can be adjusted by the first hydraulic telescopic rod 601, and the distance between the other end of the limit post 901 and the embossing platform 1 can be adjusted by the second hydraulic telescopic rod 701. At this time, the first connecting disk 603 rotates relative to the first mounting disk 602, and the second connecting disk 703 rotates relative to the second mounting disk 702, so as to change the angle of the limit post 901, thereby adapting to the inclined surface of the PVC wood-plastic board. When the angle of the limit post 901 changes, the positions of the support rods 902 on both sides of the limit post 901 in the corresponding inner sleeves 906 also change. At this time, the spring 907 in the inner sleeve 906 pushes the pressure plate 908 to move, and the pressure plate 908 squeezes the corresponding support rod 902, so as to ensure that the limit post 901 can perform a stable embossing operation;

[0037] During disassembly, drive the third hydraulic telescopic rod 12 to extend, driving the fitting block 13 to move upward, so as to support the support rod 902 at a similar position. And this group of support rods 902, fitting blocks 13, and second hydraulic telescopic rods 701 are all arranged on one side of the limit post 901, as Figure 2 described, by positioning this group of support rods 902, the positioning of the limit post 901 is realized;

[0038] Then remove the U-shaped limit plate 10 sleeved on the upper end of the first hydraulic telescopic rod 601, thereby unlocking the first hydraulic telescopic rod 601. At this time, the first hydraulic telescopic rod 601 can rotate back and forth along the connection point. Then disassemble the bolt on the first clamping plate 604 and the first connecting disk 603, so that the first connecting disk 603 is separated from the first clamping plate 604, and push the first hydraulic telescopic rod 601, so that the first hydraulic telescopic rod 601 drives the first connecting disk 603 away from the cooperating support rod 902, as Figure 2 shown, thereby facilitating the disassembly of the embossing sleeve 904;

[0039] Subsequently, remove the docking sleeve 905 on the side close to the threaded limit cylinder 903 from one end of the support rod 902, and rotate the threaded limit cylinder 903 so that the threaded limit cylinder 903 disengages from the support rod 902, thereby releasing the locking of the limit ring plate 909. Push the knurled sleeve 904, and the knurled sleeve 904 moves along the support rod 902 away from the surface of the limit post 901 until it leaves the support rod 902, thus realizing the removal of the knurled sleeve 904. Subsequently, reinstall the appropriate knurled sleeve 904 on the limit post 901, and reinstall the threaded limit cylinder 903 on the support rod 902 at the corresponding position. Limit the limit ring plate 909 and the knurled sleeve 904 through the threaded limit cylinder 903, and then continue to install the first clamping plate 604 and the U-shaped limit plate 10, thereby realizing the replacement of the knurled sleeve 904. The shape of the knurled sleeve 904 can also be adjusted as needed, for example, frustum-shaped as shown in Figure 3 . The whole process is simple to disassemble and convenient to install, without the need for auxiliary equipment such as a crane or sling, improving the disassembly efficiency.

[0040] The above has described in detail an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
