Detailed Implementation

[0018] 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 protection scope of the present utility model.

[0019] Example 1: Please refer to Figures 1-4 The small-scale papermaking pulping equipment includes a base 1, a pulping machine body 2 installed at the front end of the top of the base 1, an installation bracket 8 installed at the rear end of the top of the base 1, a crushing cylinder 10 installed at the front end of the installation bracket 8, and also includes a crushing structure for crushing large-volume raw materials and a shielding structure for covering the top of the crushing cylinder 10.

[0020] The crushing structure includes a drive motor 6, which is installed on one side of the rear end of the crushing cylinder 10. A drive rod 11 is installed at the output end of the drive motor 6. A first crushing roller 5 is installed on the outer wall of the drive rod 11, and a drive gear 3 is installed at the front end of the drive rod 11. A driven rotating rod 14 is rotatably installed on the rear end of the crushing cylinder 10 away from the drive rod 11. A second crushing roller 7 is installed on the outer wall of the driven rotating rod 14, and a driven gear 9 is installed at the front end of the driven rotating rod 14. Crushing blades 15 are installed on both sides inside the crushing cylinder 10.

[0021] The shielding structure includes a chute 13, which is opened inside the front and rear ends of the top of the crushing cylinder 10. A bidirectional threaded rod 12 is rotatably installed on one side of the chute 13. Threaded blocks 16 are fitted on the two opposite parts of the outer wall of the bidirectional threaded rod 12. A synchronous belt 18 is installed on one end of the bidirectional threaded rod 12. A knob 17 is installed on the front end of one side of the synchronous belt 18. A cover plate 4 is installed on the top of the threaded block 16.

[0022] The front end of the drive rod 11 passes through the crushing cylinder 10, and the front end of the drive rod 11 extends to the front of the crushing cylinder 10;

[0023] The front end of the driven rotating rod 14 passes through the crushing cylinder 10 and extends to the front of the crushing cylinder 10;

[0024] The driving gear 3 and the driven gear 9 approach each other and mesh with each other;

[0025] One end of each bidirectional threaded rod 12 passes through the crushing cylinder 10, and one end of each bidirectional threaded rod 12 extends to one side of the crushing cylinder 10.

[0026] Specifically, such asFigure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in the figure, when using the mechanism, the rotation direction of the bidirectional threaded rod 12 is adjusted, the threaded block 16 moves in the direction of approaching each other on the outer wall of the bidirectional threaded rod 12, the cover plate 4 is driven by the threaded block 16 to approach each other, and a gap is left between the cover plate 4 for the raw materials to pass through, which prevents the workers from directly contacting the first crushing roller 5 and the second crushing roller 7, causing danger. If the first crushing roller 5 and the second crushing roller 7 need to be repaired, the knob 17 is rotated in the opposite direction, so that the cover plate 4 moves away, the shielding at the top of the crushing cylinder 10 is removed, and the repair can be performed.

[0027] The working principle is as follows: the worker rotates the knob 17 to control the synchronous belt 18 to drive the bidirectional threaded rod 12 to rotate. Since the threaded block 16 is located at two parts of the outer wall of the bidirectional threaded rod 12 in the reverse direction, during the rotation of the bidirectional threaded rod 12, the threaded block 16 can move on the outer wall of the bidirectional threaded rod 12 in the reverse direction. The rotation direction of the bidirectional threaded rod 12 is adjusted, the threaded block 16 moves in the direction of approaching each other on the outer wall of the bidirectional threaded rod 12, the cover plate 4 is driven by the threaded block 16 to approach each other, and a gap is left between the cover plate 4 for the raw materials to pass through, and then the worker can put the raw materials into the inside of the crushing cylinder 10 through the gap. At this time, the driving motor 6 is started, the driving rod 11 is driven to rotate by the driving motor 6, the driving gear 3 and the first crushing roller 5 are driven to rotate by the driving rod 11. Since the driving gear 3 is meshed with the driven gear 9, the driven gear 9 and the second crushing roller 7 can be driven to rotate by the driving gear 3, and the rotation directions of the two are opposite. The raw materials are crushed by the first crushing roller 5 and the second crushing roller 7, and fall into the inside of the beating machine main body 2 through the bottom of the crushing cylinder 10 for beating.

[0028] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims.
