[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] For an example, please refer to... Figure 1-5 This utility model provides a technical solution:

[0025] A mixer for the production of PVC decorative materials includes a mixing tank 1, a crushing and screening structure 2 connected to the end face of the mixing tank 1, a mixing and stirring structure 3 connected to the inner cavity of the mixing tank 1, and a controller 4 connected to the side wall of the mixing tank 1 via a connecting seat.

[0026] In this embodiment, reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The crushing and screening structure 2 includes a connecting housing 201, which is connected to the feed inlet on the end face of the mixing tank 1. A feed funnel 202 is connected to the end face of the connecting housing 201. A drive motor 203 is connected to the side wall of the connecting housing 201 via a connecting seat. The drive end of the drive motor 203 is connected to a drive rod 204 via a coupling. A drive gear 205 is connected to the side wall of the drive rod 204. A driven gear 206 is meshed with the side wall of the drive gear 205. A rotating rod 207 is connected to the center of the driven gear 206. A crushing roller 208 is connected to the side wall of the drive rod 204 and the rotating rod 207 and located in the inner cavity of the connecting housing 201. Both ends of the rotating rod 207 are connected to rotating paddle plates 209. A connecting paddle 210 is provided below the rotating paddle plate 209. One end of the connecting paddle 210 is connected to a movable screen 211 through a connecting rod and located in the inner cavity of the connecting housing 201. The two ends of the movable screen 211 are symmetrically connected to return springs 212. The other end of the return springs 212 is connected to the side wall of the inner cavity of the connecting housing 201. Limiting sliders 213 are symmetrically connected to the side wall of the movable screen 211. Limiting slide rails 214 are connected to the limiting sliders 213. The limiting slide rails 214 are connected to the side wall of the inner cavity of the connecting housing 201. A guide port 215 is connected to the side wall of the movable screen 211.

[0027] Based on the above structure and the connection relationship of the above structure, the controller 4 controls the drive motor 203 to run. When the drive end of the drive motor 203 rotates, it sequentially drives the drive rod 204, drive gear 205, driven gear 206, rotating rod 207, crushing roller 208 and rotating deflector 209 to rotate. When the crushing roller 208 rotates, the material is crushed. When the rotating deflector 209 rotates, it drives the connecting rod 210 and the moving screen 211 to move in the inner cavity of the connecting housing 201. At the same time, the return spring 212 is compressed. When the rotating deflector 209 separates from the connecting rod 210, the potential energy stored in the return spring 212 is released instantaneously, so that the moving screen 211 moves quickly in the inner cavity of the connecting housing 201, thereby allowing the crushed material to be screened into the inner cavity of the mixing tank 1. At the same time, larger material particles are discharged from the guide port 215 on the side wall of the moving screen 211.

[0028] The drive motor 203 is electrically connected to the controller 4 via a wire, and the controller 4 can control the operation of the drive motor 203. The drive rod 204 is connected to the side wall of the connecting housing 201 via a bearing seat, and the drive rod 204 and the bearing seat are rotatably connected. The rotating rod 207 is connected to the side wall of the connecting housing 201 via a bearing seat, and the rotating rod 207 and the bearing seat are rotatably connected. The limiting slider 213 has a groove corresponding to the limiting slide rail 214, and the limiting slide rail 214 and the groove are slidably connected. When the drive rod 204 rotates, it can drive the moving screen 211 to move.

[0029] In this embodiment, reference Figure 1 , Figure 2 and Figure 5 The mixing structure 3 includes a fixed housing 301 and a rotating motor 302. The fixed housing 301 and the rotating motor 302 are connected to the end face of the mixing tank 1. The drive end of the rotating motor 302 is connected to a drive rod 303 via a coupling. The other end of the drive rod 303 is connected to a drive bevel gear 304. A rotating bevel gear 305 and a driven bevel gear 306 are meshed on the side wall of the drive bevel gear 304. A rotating rod 307 is connected to the center of the rotating bevel gear 305. Multiple sets of stirring rods 308 are connected to the side wall of the rotating rod 307 and inside the mixing tank 1. Multiple sets of rotating stirring blades 309 are connected to the stirring rods 308. A driven rod 310 is provided at the center of the driven bevel gear 306 and on the outer wall of the rotating rod 307. A driven stirring blade 311 is connected to the side wall of the driven rod 310.

[0030] Based on the above structure and the connection relationship of the above structure, the controller 4 controls the operation of the rotating motor 302. When the drive end of the rotating motor 302 rotates, it drives the drive rod 303 and the drive bevel gear 304 to rotate in sequence. When the drive bevel gear 304 rotates, it drives the rotating bevel gear 305 to rotate clockwise and drives the driven bevel gear 306 to rotate counterclockwise, thereby driving multiple sets of stirring rods 308 and driven stirring blades 311 to rotate in opposite directions.

[0031] The rotating motor 302 is electrically connected to the controller 4 via a wire, and the controller 4 can control the operation of the rotating motor 302. The drive rod 303 is connected to the end face of the mixing tank 1 via a bearing seat, wherein the drive rod 303 and the bearing seat are rotatably connected. The rotating rod 307 is connected to the end face of the fixed box 301 via a bearing seat, wherein the rotating rod 307 and the bearing seat are rotatably connected. The driven rod 310 is connected to the end face of the mixing tank 1 via a bearing seat, wherein the driven rod 310 and the bearing seat are rotatably connected. The rotating stirring blade 309 is connected to the stirring rod 308 via a bearing, wherein the rotating stirring blade 309 and the bearing are rotatably connected. The rotation of the drive rod 303 can drive the rotating rod 307 and the driven rod 310 to rotate.

[0032] When using the mixer for PVC decorative material production, first connect the power supply to the device to put it into operation. The controller 4 controls the drive motor 203 to run. When the drive motor 203 rotates, it sequentially drives the drive rod 204, drive gear 205, driven gear 206, rotating rod 207, crushing roller 208, and rotating deflector 209 to rotate. The rotation of the crushing roller 208 crushes the material. The rotation of the rotating deflector 209 drives the connecting rod 21. The moving screen 211 moves within the inner cavity of the connecting housing 201, while the return spring 212 is compressed. When the rotating plate 209 separates from the connecting rod 210, the potential energy stored in the return spring 212 is released instantaneously, causing the moving screen 211 to move rapidly within the inner cavity of the connecting housing 201. This allows the crushed material to be screened into the inner cavity of the mixing tank 1, while larger material particles are discharged from the guide port 215 on the side wall of the moving screen 211, thus improving the quality of material mixing during the mixing process.

[0033] The controller 4 controls the operation of the rotating motor 302. When the drive end of the rotating motor 302 rotates, it drives the drive rod 303 and the drive bevel gear 304 to rotate in sequence. When the drive bevel gear 304 rotates, it drives the rotating bevel gear 305 to rotate clockwise and the driven bevel gear 306 to rotate counterclockwise. This drives multiple sets of stirring rods 308 and driven stirring blades 311 to rotate in opposite directions, which can make the material more uniform and improve the efficiency of material stirring.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
