Description

Technical Field

[0001] This utility model belongs to the field of sheet metal cleaning technology, specifically relating to a device for cleaning and removing burrs from extruded surfaces. Background Technology

[0002] Wood-plastic composite (WPC) is a high-quality material that uses plastic to replace wood. It is made from nearly 100% recycled plastics and recycled wood flour, and boasts excellent performance and recyclability. WPC flooring is an important application area for WPC materials. However, traditional first-generation WPC materials offer limited color options, with only surface co-extruded colored plastics available for two- or multi-color applications, or requiring additional manpower and resources for material splicing. Current technology offers two-color or double-layer co-extruded WPC flooring that combines the wood grain and texture of traditional first-generation WPC with a wider range of colors and functionalities.

[0003] During the processing of co-extruded sheets, some burrs will appear on the surface, which will make the sheet quality substandard and the burrs may cause harm to people. Therefore, it is necessary to clean and remove the burrs during processing. This paper proposes a co-extruded surface burr cleaning and removal device. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given the following technical problems in the existing technology: how to design a method that can remove surface burrs and improve the quality of the sheet during co-extruded sheet processing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for cleaning and removing burrs from extruded surfaces, comprising,

[0007] A heating shell is used to heat and shrink the burrs on the surface of the board into granules, which facilitates subsequent burr treatment.

[0008] A transfer assembly is provided for conveying the sheet material into the interior of the heating shell for processing and for outputting the processed sheet material. Two transfer assemblies are provided and located on both sides of the heating shell.

[0009] A polishing assembly is used to polish the particles on the surface of the plate after it has been heated by the heating shell. The polishing assembly is located on the left side of the heating shell and on the right side of the left transmission assembly.

[0010] A transmission assembly is used to synchronize the operation of the transmission assembly and the polishing assembly to ensure the operation of the equipment. The transmission assembly is installed on the corresponding two transmission assemblies and the polishing assembly.

[0011] Guide rollers are used to limit the two sides of the plate to ensure the stability of the plate's position during transmission. The guide rollers are installed on both sides of the heating shell.

[0012] Furthermore, a hot air gun is installed in the heating shell, and a through cavity is opened in the heating shell from left to right. The hot air gun is located at the top center of the through cavity with its air outlet facing downwards.

[0013] By adopting the above technical solution, hot air is blown by the hot air gun in the heating shell, which heats and shrinks the burrs on the surface of the board into granules, allowing the board to pass through the cavity.

[0014] Furthermore, the transmission assembly includes a bracket, on which two mounting seats are mounted on both sides of the top of the bracket. A mounting seat is rotatably connected between the two mounting seats on one side. A transmission cylinder is mounted on the mounting seat. Two mounting plates are mounted on both sides of the top of the bracket. An adjustment frame is mounted on the inner side of the mounting plate. A movable seat is slidably connected to the side of the adjustment frame that is close to each other. A screw is rotatably connected to the top of each movable seat. A turntable is fixedly connected to the top of each screw. An auxiliary roller is rotatably connected between the two movable seats on one side.

[0015] By adopting the above technical solution, during use, the turntable is rotated according to the thickness of the sheet material, causing the screw to rotate and move on the adjustment frame, thereby moving the moving seat and changing the position of the auxiliary roller, which can adapt to sheets of different thicknesses.

[0016] Furthermore, limit strips are installed on the inner walls of both the left and right sides of the opening of the adjustment frame, the screw is threadedly connected to the top of the adjustment frame, and the guide roller located on the right side is rotatably installed on the top left side of the bracket and is arranged front and back.

[0017] By adopting the above technical solution, the moving seat can be restricted by the limiting strip to prevent it from falling off and ensure stable movement. The threaded connection can restrict the screw on the one hand and rotate it on the other hand to achieve the purpose of vertical movement.

[0018] Furthermore, the polishing assembly includes a support bracket 2, on both sides of the top of the support bracket 2, several pairs of screw rods 2 are fixedly connected, and the top of each pair of screw rods 2 is fixedly connected to the same connecting plate. Each pair of screw rods 2 is slidably connected to two vertically distributed rotating seats. Nuts are provided on both the upper and lower sides of the connection between each rotating seat and the screw rod 2. The nuts are threaded onto the screw rod 2. The same rotating rod 2 is rotatably connected to the two rotating seats arranged in front and behind. A polishing brush is installed on the upper rotating rod 2, and a roller is installed on the lower rotating rod 2.

[0019] By adopting the above technical solution, when the board passes between the polishing brush and the roller, the polishing brush will clean the particles on the top of the board and perform polishing treatment, thereby improving the quality of the board.

[0020] Furthermore, the two rotating seats, which are arranged front to back and connected to the same rotating rod, are on the same horizontal plane. The two ends of the rotating seats are respectively connected to the two screw rods of the same pair. The guide roller located on the left side is installed on the top right side of the bracket and is arranged front to back.

[0021] By adopting the above technical solution, the two front and rear rotating seats are connected to a rotating rod II, which ensures the stable rotation of the rotating rod II and restricts the rotating seats from both ends to ensure stable use.

[0022] Furthermore, the transmission assembly includes a gear, a first sprocket, a first chain, a second sprocket, and a second chain. Two gears are provided, and the two gears are respectively mounted on the two leftmost vertically distributed rotating rods. Multiple second chains are provided, and each second chain is respectively mounted on a first rotating rod. Multiple first sprockets are installed, and each first sprocket is respectively mounted on the front side of a corresponding second rotating rod. Two gears mesh with each other. The second sprockets are mounted on multiple second chains and first sprockets on the same horizontal plane, and the multiple first sprockets located above are mounted on the same first chain.

[0023] By adopting the above technical solution, the right-hand rotating rod is connected to a power source, such as a motor. The power source drives the rightmost rotating rod to rotate, which in turn causes the sprocket two to drive several chains two and the lower sprocket one to rotate. This causes the transmission cylinder one, rotating rod two, and gear to rotate in the same direction. Then, the lower gear drives the upper gear to rotate, and the gear drives the coaxial sprocket one to rotate. This, in turn, drives the upper sprocket one and the polishing brush to rotate through the chain one. The roller transports the material, and the polishing brush polishes the material. The gear meshing makes the polishing brush and the roller rotate in opposite directions, but it can transport the material to the left.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. This utility model uses a built-in hot air gun in the heating shell to heat and shrink the burrs on the surface of the board into granules through directional hot air, so that the subsequent polishing process is more thorough. The transmission component adopts a screw and a moving base. The screw drives the auxiliary roller to rise and fall through the rotating turntable, which can quickly adapt to boards of different thicknesses.

[0026] 2. This utility model employs a dual-transmission component and a linkage design with the transmission component, achieving synchronous control of sheet material conveying, heating, and polishing through a sprocket-chain-gear transmission system. After the power source drives the right-side rotating rod, it can drive the transmission cylinder, roller, and polishing brush to operate in coordination, ensuring stable sheet material transmission and consistent processing rhythm.

[0037] Reference Figures 1-3 This utility model embodiment proposes a device for cleaning and removing burrs from extruded surfaces, comprising,

[0038] Heating shell 100 is used to heat and shrink the burrs on the surface of the board into granules, which facilitates subsequent burr treatment.

[0039] The transfer assembly is used to transport the sheet material into the heating shell 100 for internal processing and to output the processed sheet material. There are two transfer assemblies located on both sides of the heating shell 100.

[0040] The polishing component is used to polish the particles on the surface of the plate after it has been heated by the heating shell 100. The polishing component is located on the left side of the heating shell 100 and on the right side of the left transmission component.

[0041] The transmission assembly is used to synchronize the operation of the transmission assembly and the polishing assembly to ensure the operation of the equipment. The transmission assembly is installed on the corresponding two transmission assemblies and polishing assemblies.

[0042] Guide roller 200 is used to limit the two sides of the plate to ensure the stability of the plate's position during transmission. Guide roller 200 is installed on both sides of heating shell 100.

[0043] A hot air gun is installed in the heating shell 100. A through cavity is opened in the heating shell 100, which runs from left to right. The hot air gun is located at the top center of the through cavity with the air outlet facing downward. Hot air is blown by the hot air gun in the heating shell 100, which heats and shrinks the burrs on the surface of the board into granules. The through cavity allows the board to pass through.

[0044] The transmission assembly includes a bracket 101. Two mounting seats 107 are mounted on both sides of the top of the bracket 101. A mounting seat 107 is rotatably connected between the two mounting seats 107 on one side. A transmission cylinder 109 is mounted on the mounting seat 107. Two mounting plates 102 are mounted on both sides of the top of the bracket 101. An adjustment frame 103 is mounted on the inner side of the mounting plate 102.

A turntable 106 is fixedly connected to the top of each screw 104. An auxiliary roller 105 is rotatably connected between the two movable seats 1010 on one side. In use, the turntable 106 is rotated according to the thickness of the sheet material, causing the screw 104 to rotate and move on the adjustment frame 103, thereby moving the movable seat 1010 and changing the position of the auxiliary roller 105. This allows for the adaptation to sheet materials of different thicknesses.

[0045] Limiting strips are installed on the inner walls of both sides of the opening of the adjustment frame 103. The screw 104 is threadedly connected to the top of the adjustment frame 103. The guide roller 200 located on the right side is rotatably installed on the top left side of the bracket 101 and is arranged front and back. The limiting strips can restrict the moving seat 1010 to prevent it from falling off and ensure stable movement. The threaded connection can restrict the screw 104 on the one hand and rotate it to achieve the purpose of vertical movement on the other hand.

[0046] The polishing assembly includes a bracket 307. Several pairs of screws 301 are fixedly connected to the top of the bracket 307 on both sides. The top of each pair of screws 301 is fixedly connected to the same connecting plate 302. Two vertically distributed rotating seats 303 are slidably connected to each pair of screws 301. Nuts 304 are provided on the upper and lower sides of the connection between each rotating seat 303 and the screw 301. The nuts 304 are threaded onto the screws 301. The same rotating rod 305 is rotatably connected to the two rotating seats 303. A polishing brush 306 is installed on the upper rotating rod 305, and a roller is installed on the lower rotating rod 305. When the board passes between the polishing brush 306 and the roller, the polishing brush 306 cleans the particles on the top of the board and polishes it, improving the quality of the board.

[0047] Two rotating seats 303, arranged front to back and connected to the same rotating rod 305, are on the same horizontal plane. The two ends of the rotating seats 303 are respectively connected to two screws 301 of the same pair. The guide roller 200 located on the left side is installed on the top right side of the bracket 307 and is arranged front to back. The two rotating seats 303 are connected to a rotating rod 305 to ensure the stable rotation of the rotating rod 305. The rotating seats 303 are restricted from both ends to ensure stable use.

[0048] The transmission assembly includes gear 401, sprocket 402, chain 403, sprocket 404, and chain 405. Two gears 401 are provided, mounted on the two leftmost vertically distributed rotating rods 305. Multiple chains 405 are provided, each mounted on a rotating rod 108. Multiple sprockets 402 are provided, each mounted on the front side of a corresponding rotating rod 305. The two gears 401 mesh with each other. Sprockets 404 are mounted on multiple chains 405 and sprockets 402 on the same horizontal plane. The multiple upper sprockets 402 are mounted on the same chain 403. The transmission is achieved by connecting the rotating rod on the right side... A power source, such as a motor, is connected to a 108-axis. The power source drives the rightmost rotating rod 108 to rotate, which in turn causes the sprocket 404 to drive several chains 405 and the lower sprocket 402 to rotate. This causes the transmission cylinder 109, rotating rod 305, and gear 401 to rotate in the same direction. Then, the lower gear 401 drives the upper gear 401 to rotate, and the gear 401 drives the coaxial sprocket 402 to rotate. This, in turn, drives the upper sprocket 402 and polishing brush 306 to rotate via a chain 403. The roller transports the material, and the polishing brush 306 polishes the material. The gear 401 meshes, causing the polishing brush 306 and the roller to rotate in opposite directions, but it can still transport the material to the left.

[0049] The specific implementation method is as follows: In use, the power source drives the rightmost rotating rod 108 to rotate, which in turn causes the sprocket 404 to drive several chains 405 and the lower sprocket 402 to rotate. This causes the transmission cylinder 109 on the rotating rod 108 and the roller on the rotating rod 305 to rotate in the same direction. Then, the lower gear 401 drives the upper gear 401 to rotate, and the gear 401 drives the coaxial sprocket 402 to rotate. This, in turn, drives the upper sprocket 402 and the polishing brush 306 to rotate via the chain 403, thus polishing. The brush 306, transmission cylinder 109, and rotating rollers transport the sheet material. The sheet material enters from the right side and is transported between the auxiliary roller 105 and transmission cylinder 109 to the heating shell 100. Hot air is blown from the hot air gun in the heating shell 100, which heats and shrinks the burrs on the surface of the sheet material into granules. These granules then pass through the polishing brush 306, which cleans the granules while transporting the sheet material. The sheet material is then sent out from the transmission cylinder 109 on the left side. This process treats the sheet material to produce a smooth surface with clear and delicate texture.

[0050] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
