Technical Field
[0001] The utility model relates to the technical field of rubber production and processing, in particular to a crushing mechanism for rubber production and processing. Background Art
[0002] Rubber is an elastic polymer. Rubber can be obtained from the sap of some plants or can be artificial. Both have quite a lot of applications and products, such as tires, gaskets, etc. Recycling and reusing rubber products is an economical and environmentally friendly practice. When recycling and reusing, crushing rubber is the first process, and a crusher is needed during the process of crushing rubber.
[0003] Currently, when the existing waste rubber crusher is in use, when the hardness of the rubber in the crushing chamber is too high or the particle size is too large, it will cause incomplete crushing in the crushing chamber, resulting in uneven discharge. Therefore, it is necessary to manually screen out larger particles of rubber for re-crushing. The entire screening efficiency is low and it wastes manpower. For this reason, we propose a crushing mechanism for rubber production and processing to solve the above problems. Summary of the Utility Model

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figures 1-4, A crushing mechanism for rubber production and processing, including a crushing body 1. There is a feeding port 2 at the top of the crushing body 1. The specific crushing principle of the crushing body 1 is a mature existing technology and will not be elaborated here. There is a discharging port 3 at the bottom of the crushing body 1. A fixed block 4 is connected to the inner wall at the bottom of the crushing body 1, and a motor 5 is installed inside the fixed block 4. The two sides of the motor 5 are symmetrically connected with rotating shafts 6, and the other ends of the rotating shafts 6 are connected to a turning plate 7. The motor 5 is also a mature existing technology and can drive the simultaneous rotation of the two groups of rotating shafts 6, so that the sieve plate 8 can be forced to turn, so as to realize the opening and closing of the discharging port 3. A sieve plate 8 is arranged inside the turning plate 7. A bracket 15 is welded to the bottom of the crushing body 1. The bottom of the crushing body 1 is arranged in an inclined shape. Therefore, during the feeding process, qualified materials will pass through the mesh holes opened inside the sieve plate 8 under the action of gravity, while unqualified materials will be blocked by the sieve plate 8.
[0023] Further, referring to Figure 3 and Figure 4 it can be known that rectangular grooves are opened inside the turning plate 7, and fixing plates 9 are respectively connected to the corner positions of the rectangular grooves. The inside of the sieve plate 8 is respectively connected to the fixing plates 9 through bolts. Through the mutual cooperation of the fixing plates 9 and the bolts, it is convenient for the staff to replace the sieve plate 8 with a suitable specification according to the use requirements, so as to effectively improve the applicability during the use of this device.
[0024] Further, referring to Figure 3 it can be known that handles 10 are symmetrically connected to the sides of the sieve plate 8, and anti-slip particles are evenly distributed on the outer surface of the handles 10. Through the mutual cooperation of the handles 10 and the anti-slip particles, it is convenient for the staff to disassemble and install the sieve plate 8.
[0025] Further, referring to Figure 3 and Figure 4 it can be known that a support frame 11 is connected to the side of the turning plate 7, and a cylinder 12 is installed at the center position of the support frame 11. The output end of the cylinder 12 is connected with an impact bar 13. The telescopic principle of the cylinder 12 is an existing technology. Driven by the cylinder 12, the front and back movement of the impact bar 13 can be realized to realize the intermittent knocking on the sieve plate 8, so as to effectively prevent the sieve plate 8 from being blocked. In addition, the gap between the impact bar 13 and the sieve plate 8 is relatively large when the impact bar 13 retracts, so as to meet the disassembly requirements of the sieve plate 8. And when the sieve plate 8 rotates to a horizontal state, the discharging port 3 can be opened. At this time, through the knocking of the impact bar 13, the unqualified rubber attached to the inner side of the sieve plate 8 can be knocked off.
[0026] Further, referring to Figure 4It can be known that a buffer pad is provided on the side of the impact bar 13 close to the sieve plate 8, and a cavity is formed inside the buffer pad. The rubber pad and the cavity are not shown in the figure. Through the mutual cooperation of the two, it is possible to prevent the impact bar 13 from directly colliding with the sieve plate 8 rigidly, so as to protect the sieve plate 8, thereby effectively ensuring the service life of the sieve plate 8. By providing the cavity, the buffering effect on the impact force can be further improved.
[0027] Furthermore, referring to Figure 4 It can be known that guide rods 14 are symmetrically connected to the sides of the impact bar 13, and guide grooves adapted to the guide rods 14 are formed inside the support frame 11. Through the mutual cooperation of the guide rods 14 and the guide grooves, the stability during the operation of the cylinder 12 can be ensured.
[0028] Furthermore, referring to Figure 3 It can be known that two groups of support frames 11 are provided, and the two groups of support frames 11 are symmetrically distributed about the central axis of the sieve plate 8. Since two groups of support frames 11 are provided, two groups of cylinders 12, impact bars 13 and guide rods 14 are also provided. By providing two groups of knocking components, the knocking effect on the sieve plate 8 can be improved, and the dredging effect on the sieve plate 8 can be improved.
[0029] Working principle: When the present utility model is in use, the staff can first put the waste rubber to be crushed into the interior of the crushing body 1 through the feed inlet 2 for crushing. Then, the staff can place the qualified material collection frame at the bottom of the sieve plate 8 so that the qualified rubber particles after crushing fall into the collection frame through the mesh holes of the sieve plate 8. During the feeding process, the cylinder 12 is intermittently started, thereby driving the impact bar 13 to intermittently impact the sieve plate 8, so that the sieve plate 8 generates vibration under force, thereby effectively preventing the mesh holes inside the sieve plate 8 from being blocked. After the collection of the qualified materials is completed, the staff can remove the qualified material collection frame and place another collection frame at the bottom of the sieve plate 8. Then, by starting the motor 5, the rotation of the rotating shaft 6 can be driven, so that the turning plate 7 and the sieve plate 8 are forced to turn. Since the bottom of the crushing body 1 is provided with an inclined structure, the large-particle materials blocked by the sieve plate 8 fall into another collection frame under the action of gravity. Through the secondary collection operation, the qualified materials and the unqualified materials can be classified, so that there is no need for the staff to manually select. The above is the entire working principle of the present utility model.

As long as the beneficial effects can be achieved, they can be implemented, so no more details will be described.

Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
