Polymer materials are materials composed of compounds with relatively high molecular weight, including rubber, plastic, fiber, coating, adhesive and polymer-based composite materials. Polymers are forms of life. All living organisms can be regarded as a collection of polymers. Polymer materials have a wide range of uses and can be made into plastics, rubber, fiber, coatings, etc. Polymer materials are mixed with a variety of different substances.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 As shown, the utility model provides a technical solution: a polymer material crushing device that is convenient for discharging, comprising:

[0024] The side wall of the pulverizing shell 1 is provided with a rotating column 10 inserted into the inside of the grid plate 3, the side wall of the pulverizing shell 1 is provided with a first discharge port 4, the grid plate 3 is placed inside the first discharge port 4, and the inside of the pulverizing shell 1 is provided with a plurality of mounting grooves 5 placed below the first discharge port 4 and connected to the first discharge port 4, and the plurality of mounting grooves 5 are each provided with an electric push rod 6 for supporting the grid plate 3, a through groove 33 connected to the filter screen 12 is provided at the bottom of the grid plate 3, and a through groove 33 connected to the upper end surface of the filter screen 12 is provided on the side of the grid plate 3 close to the first discharge port 4 The discharge chute 31 is designed so that the telescopic shaft on the electric push rod 6 loses its support for the grid plate 3, and the grid plate 3 rotates downward around the rotating column 10. At this time, the filter screen 12 is in a downward tilted state, and the polymer materials that have not passed the filter screen 12 inside the grid plate 3 move downward along the inclined surface of the filter screen 12 and flow out from the first discharge port 4 through the discharge chute 31, thereby facilitating the discharge operation of the polymer materials on the surface of the filter screen 12. The inclined discharge speed is fast, saving discharge time, thereby improving the crushing efficiency.

[0025] Reference Figure 2 An avoidance groove 1001 is provided inside the pulverizing shell 1 for avoiding the rotation of the grid plate 3 around the rotating column 10. This design avoids interference when the grid plate 3 rotates by using the avoidance groove 1001.

[0026] Reference Figure 3 and Figure 4 A baffle 16 is arranged at the bottom of the grid plate 3, which is inclined downward and is used to guide the polymer material filtered by the filter screen 12. This design uses the baffle 16 to be inclined, which is convenient for guiding the polymer material filtered by the filter screen 12, and at the same time guides the polymer material flowing out from the bottom of the filter screen 12, so as to avoid the polymer material from flowing into the first discharge port 4, thereby improving the rationality of the design.

[0027] Reference Figure 3 A plurality of first vibration motors 32 are arranged inside the grid plate 3, and a force block 7 is provided on the side wall of the grid plate 3. This design increases the speed at which the polymer material on the surface of the filter screen 12 moves downward along its surface by using the first vibration motor 32, thereby increasing the discharging speed, saving the discharging time, and thus improving the crushing efficiency.

[0028] Reference Figure 2A second discharge port 9 is provided on the side wall of the pulverizing shell 1 and is placed below the first discharge port 4. An inclined plate 8 is provided inside the pulverizing shell 1, which is inclined downward and inserted into the second discharge port 9. A plurality of second vibration motors 81 are provided inside the inclined plate 8. This design facilitates the guidance of the polymer material filtered out from the bottom of the filter screen 12 to flow out of the second discharge port 9 by using the second vibration motor 81 and the inclined plate 8, thereby facilitating the discharge of the material. A pair of guide plates 15 for guiding the polymer material entering from the feed channel 2 to between the first pulverizing roller 13 and the second pulverizing roller 14 are symmetrically provided on the upper side of the inner wall of the pulverizing shell 1. The lower side of the inner wall of the discharge trough 31 is flush with the upper end surface of the filter screen 12, thereby improving the rationality of the design.

[0029] Reference Figure 1-Figure 4 As an embodiment of the present invention: when it is necessary to crush the polymer material, the staff sends the polymer material from the feed channel 2 to the inside of the crushing shell 1, and sends it to between the first crushing roller 13 and the second crushing roller 14 under the guidance of the guide plate 15, so that the crushing motor 11 rotates to drive the second crushing roller 14 to rotate, and the first crushing roller 13 is driven to rotate under the action of the gear meshing connection between the first crushing roller 13 and the second crushing roller 14, wherein the first crushing roller 13 and the second crushing roller 14 are connected by gears in the prior art, specifically, the first crushing roller 13 and the second crushing roller 14 are both provided with gears, and the two are connected by gear meshing, so that the first crushing roller 13 and the second crushing roller 14 are rotated to crush the polymer material, and the crushed polymer material enters the filter screen 12 inside the grid plate 3 for passing through Filter, the filtered polymer material flows out from the second discharge port 9 along the inclined plate 8. When the crushed polymer material is filtered, the electric push rod 6 is operated to make the telescopic shaft on it move downward and lose the support of the grid plate 3. The grid plate 3 thus tilts and rotates downward around the rotating column 10. At this time, the filter screen 12 is in a downward tilted state. The polymer material that has not passed the filter screen 12 inside the grid plate 3 moves downward along the surface of the inclined filter screen 12, passes through the discharge groove 31 and flows out from the first discharge port 4. At the same time, the first vibration motor 32 is operated to drive the grid plate 3 to vibrate, thereby vibrating the filter screen 12, accelerating the speed at which the polymer material on the surface of the filter screen 12 moves downward to discharge, thereby facilitating the discharge operation of the polymer material on the surface of the filter screen 12, and the inclined discharge speed is fast, saving discharge time, thereby improving the crushing efficiency.

[0030] When the discharge is completed, force is applied to the force block 7 to make the grid plate 3 rotate around the rotating column 10, so that the grid plate 3 moves upward and drives the filter screen 12 inside the grid plate 3 to return to the initial position, and then the electric push rod 6 is operated to make the telescopic axis thereon move upward to support the bottom of the grid plate 3, so that the upper end surface of the grid plate 3 is flush with the upper side of the inner wall of the first discharge port 4. At this time, the grid plate 3 is in a horizontal state, which improves the practicality of the utility model.
