[0025] 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.

[0026] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0027] This application discloses an easy-to-operate rubber processing screen replacement structure. (Refer to...) Figure 1 and Figure 7 An easy-to-operate rubber processing screen replacement structure includes a screening device body 1, a convenient disassembly mechanism 2 provided on the inner side of the screening device body 1, and a collection mechanism 3 provided at the bottom of the screening device body 1.

[0028] The easy-to-remove mechanism 2 includes a fixed frame 202, the surface of which is fixedly connected to the body 1 of the screening device. A filter screen 201 is movably connected to the inner cavity of the fixed frame 202. A support frame 209 is fixedly connected to the inner cavity of the filter screen 201. The top of the support frame 209 is movably connected to the bottom of the filter screen 201. Four snap-fit ​​posts 204 are movably connected to the inner cavity of the filter screen 201. One end of each snap-fit ​​post 204 is snapped into the inner cavity of the fixed frame 202. A fixing strip 205 is fixedly connected to the surface of each snap-fit ​​post 204. The surface of the fixing strip 205 is movably connected to the inner cavity of the filter screen 201.

[0029] Reference Figure 4 The inner cavity of the filter screen 201 is movably connected to a pull handle 207 via a rotating shaft. By setting the pull handle 207, the filter screen 201 can be more easily driven out of the inner cavity of the fixed frame 202 by rotating and pulling the pull handle 207.

[0030] Reference Figure 3 One end of the snap-fit ​​post 204 is fixedly connected to a spring 206. One end of the spring 206 is fixedly connected to the inner cavity of the filter screen 201. Through the spring 206, due to the elasticity of the spring 206, the snap-fit ​​post 204 is always snapped into the inner cavity of the fixed frame 202 without being subjected to external force.

[0031] Reference Figure 3 The inner cavity of the filter screen 201 is fixedly connected with four fixing blocks 203. The fixing blocks 203 are L-shaped. By setting the fixing blocks 203, when the fixing strip 205 is snapped into the inner cavity of the fixing block 203, the position of the snap-fit ​​post 204 is fixed, so the spring 206 will not deform. This makes it convenient for the staff to pull the fixing strip 205 in sequence, so that the fixing strip 205 drives the snap-fit ​​post 204 to disengage from the inner cavity of the fixing frame 202, thereby making it easy to remove the filter screen 201.

[0032] Reference Figure 4 The surface of the filter screen 201 is provided with a semi-circular groove 208. The bottom of the inner cavity of the semi-circular groove 208 is lower than the surface of the pull handle 207. Because the bottom of the inner cavity of the semi-circular groove 208 is lower than the surface of the pull handle 207, it is convenient for the staff to pull out the pull handle 207 through the semi-circular groove 208 and drive the filter screen 201 to move.

[0033] Reference Figure 5The collection mechanism 3 includes a protective cover 301. The top of the protective cover 301 is fixedly connected to the surface of the screening device body 1. The inner cavity of the protective cover 301 is movably connected to a collection box 302. The surface of the collection box 302 is fixedly connected to a handrail 304. By setting the protective cover 301, the collection box 302 and the handrail 304 to work together, the impurities after being screened by the filter screen 201 can be collected to prevent the impurities from being thrown out when passing through the filter screen 201, thereby polluting the working environment of the staff.

[0034] Reference Figure 5 and Figure 6 A fixing frame 303 is fixedly connected to the surface of the protective cover 301. A fixing column 305 is fixedly connected to the inner cavity of the fixing frame 303. A snap-fit ​​strip 306 is movably connected to the surface of the fixing column 305. The surface of the snap-fit ​​strip 306 is movably connected to the surface of the collection box 302. By setting the fixing frame 303, the fixing column 305 and the snap-fit ​​strip 306 to work together, the snap-fit ​​strip 306 can be moved to contact the collection box 302, thereby fixing the position of the collection box 302 and preventing the screening device body 1 from shaking the collection box 302 and detaching it from the inside of the protective cover 301 during operation.

[0035] Reference Figure 6 A torsion spring 307 is fitted on the surface of the fixing column 305. One end of the torsion spring 307 is fixedly connected to the surface of the snap-fit ​​strip 306, and the other end of the torsion spring 307 is fixedly connected to the inner cavity of the fixing frame 303. Through the setting of the torsion spring 307, the snap-fit ​​strip 306 always rotates counterclockwise and contacts the collection box 302 without being affected by external force, thereby fixing the collection box 302.

[0036] Working principle: When the filter screen 201 needs to be replaced, first pull the locking strip 306 to disengage it from the surface of the collection box 302. Then pull the handle 304, which will cause the collection box 302 to disengage from the inner cavity of the protective cover 301. After the collection box 302 is disengaged, you can reach into the inner cavity of the protective cover 301 through the empty space where the collection box 302 was originally located and pull the fixing strip 205. The fixing strip 205 will cause the locking post 204 to disengage from the inner cavity of the fixing frame 202. At the same time, the spring 206 will deform. When the fixing strip 205 moves to the appropriate position, rotate the fixing strip 205 to lock it into the inner cavity of the fixing block 203. This prevents the spring 206 from deforming and causing the locking post 204 to re-lock into the inner cavity of the fixing frame 202. When all four locking posts 204 have disengaged from the inner cavity of the fixing frame 202 in the above manner, the semi-circular groove 208 will... Pull out the handle 207 through the gap. Pulling the handle 207 causes the filter screen 201 to detach from the inner cavity of the fixed frame 202. Then, place a new filter screen 201 into the inner cavity of the fixed frame 202. Next, pull the fixing strip 205 to disengage it from the locking block 203. Due to the elasticity of the spring 206, the locking post 204 is re-locked into the inner cavity of the fixed frame 202, thereby fixing the position of the filter screen 201. Then, rotate the locking strip 306 and push the collection box 302 into the inner cavity of the protective cover 301. Then, release the locking strip 306. Due to the elasticity of the torsion spring 307, the locking strip 306 rotates and re-contacts the surface of the collection box 302, thereby fixing the position of the collection box 302. When the screening device body 1 works to screen the raw material on the surface of the filter screen 201, the screened impurities will fall directly into the inside of the collection box 302 or fall into the collection box 302 through the guide structure on the protective cover 301 and be collected.

[0037] 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.
