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

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a grinding apparatus for plastic production. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6A grinding device for plastic production includes a grinding mill 1. The grinding mill 1 includes a body 101. The top of the body 101 is connected to a feed inlet 102, and the bottom of the body 101 is connected to a discharge outlet 104. Support legs 105 are fixedly connected to the four corners of the bottom of the body 101. A discharge trough 106 is connected to the bottom of the left side of the body 101. A first guide plate 109 is fixedly connected to the top of the inner cavity of the body 101, and a second guide plate 108 is fixedly connected to the bottom of the inner cavity of the body 101. A first motor 103 is fixedly connected to the front side of the body 101. A first gear 110 is fixedly connected to the output end of the first motor 103. A second gear 112 is meshed with the surface of the first gear 110. A connecting shaft 111 is fixedly connected to the inner cavities of the first gear 110 and the second gear 112. A grinding roller 107 is fixedly connected to the surface of the connecting shaft 111. A cleaning mechanism 2 is installed on the back side of the body 101.

[0026] The cleaning mechanism 2 includes a rotating wheel 201 and a fixed base 202. The front side of the rotating wheel 201 is movably connected to the back side of the machine body 101. The surface of the fixed base 202 is fixedly connected to the inner cavity of the machine body 101. A fixed shaft 204 is fixedly connected to the front side of the rotating wheel 201. A scraper 203 is fixedly connected to the surface of the fixed shaft 204. The surface of the scraper 203 is movably connected to the inner cavity of the fixed base 202. One side of the scraper 203 is in contact with the surface of the grinding roller 107. A vibration mechanism 3 is installed on the right side of the machine body 101.

[0027] Reference Figure 4 The inner cavity of the rotating wheel 201 is provided with a fixing groove 209, and a fixing rod 205 is inserted into the inner cavity of the fixing groove 209. A support plate 206 is movably connected to the surface of the fixing rod 205. The front side of the support plate 206 is fixedly connected to the back side of the machine body 101. By setting the fixing groove 209, the fixing rod 205 can be inserted into the interior of the rotating wheel 201, so that the position of the rotating wheel 201 can be fixed after the scraper 203 is adjusted, preventing the position of the scraper 203 from shifting.

[0028] Reference Figure 4 A first spring 208 is fixedly connected to the top of the support plate 206, and a handle 207 is fixedly connected to the top of the first spring 208. The bottom of the handle 207 is fixedly connected to the top of the fixed rod 205. The inner cavity of the first spring 208 is sleeved on the surface of the fixed rod 205. The position of the fixed rod 205 is positioned by the first spring 208, so that when the fixed rod 205 is not under force, it can be quickly reset by the first spring 208 to restore its deformation, which makes it easy to insert the fixed rod 205 into the interior of the fixed groove 209.

[0029] Reference Figure 2 , Figure 3 and Figure 5The vibration mechanism 3 includes a second motor 301 and a moving groove 307. The left side of the second motor 301 is fixedly connected to the right side of the machine body 101. The moving groove 307 is respectively opened on the front and back sides of the inner cavity of the machine body 101. A rotating plate 306 is fixedly connected to the output end of the second motor 301. A filter plate 302 is movably connected to the bottom of the rotating plate 306. The surface of the filter plate 302 is movably connected to the inner cavity of the machine body 101. The second motor 301 can drive the rotating plate 306 to rotate. The rotation of the rotating plate 306 can strike and vibrate the surface of the filter plate 302 to prevent the filter plate 302 from becoming clogged.

[0030] Reference Figure 5 The inner cavity of the movable groove 307 is movably connected to a movable plate 304. One side of the movable plate 304 is fixedly connected to the surface of the filter plate 302. The movable plate 304 supports the position of the filter plate 302 and prevents the filter plate 302 from shifting during vibration, which would prevent the filter plate 302 from filtering normally.

[0031] Reference Figure 5 A support rod 303 is fixedly connected to the inner cavity of the moving groove 307. The surface of the support rod 303 is movably connected to the inner cavity of the moving plate 304. The support rod 303 limits the movement of the moving plate 304, thereby preventing the moving plate 304 from detaching from the inside of the moving groove 307 during the movement.

[0032] Reference Figure 5 The top and bottom of the movable plate 304 are fixedly connected with second springs 305. One end of the second spring 305 is fixedly connected to the surface of the movable groove 307. The second spring 305 supports the movable plate 304 and buffers the filter plate 302 to prevent the filter plate 302 from moving too much. When the surface of the rotating plate 306 detaches from the surface of the filter plate 302, it can drive the filter plate 302 to reset, making it easy to move again later.

[0033] Working principle: First, by pulling the handle 207 upwards, the movement of the handle 207 moves the fixed rod 205, removing it from the inside of the rotating wheel 201. Then, by gripping the rotating wheel 201 and rotating it, the rotation of the rotating wheel 201 drives the fixed shaft 204 to rotate, which in turn drives the scraper 203 to rotate, adjusting the angle of the scraper 203 until it is aligned with one side of the grinding roller 107. After the angle of the scraper 203 is adjusted, the first spring 208 restores its deformation, pushing the fixed rod 205 back to its original position. The fixed rod 205 is then inserted into the fixed groove 209, thus completing the adjustment. The position of the rotating wheel 201 is fixed to prevent the scraper 203 from shifting during use, which would cause unstable cleaning of the surface of the grinding roller 107. Subsequently, the first motor 103 drives the first gear 110 to rotate, which in turn drives the second gear 112 to rotate. The rotation of the first gear 110 and the second gear 112 drives the connecting shaft 111 to rotate, which in turn drives the grinding roller 107 to rotate in opposite directions. As the grinding roller 107 rotates, the scraper 203 scrapes away the particles or dust adhering to the surface of the grinding roller 107, preventing it from reducing grinding efficiency and shortening the service life of the grinding roller 107.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
