Description

Technical Field

[0001] This utility model belongs to the field of paper product recycling technology, and more specifically, relates to a device for recycling and crushing raw materials for yarn tube paper production. Background Technology

It has high requirements for physical strength, abrasion resistance, stiffness, dimensional stability, and a certain degree of water resistance. Its core raw material is pulp fiber. Excess wood pulp fiber generated during the production of yarn tube paper, including edge-trimmed waste paper, substandard paper rolls, and sheets, is recycled and reused, which is a crucial step in the papermaking industry, reducing costs, pollution, and conserving resources. For example, a waste paper recycling shredding device disclosed in patent application CN202420616750.0 (application date March 28, 2024) uses a slitting device and shredder to separate the shell into upper and lower spaces through a partition plate. The slitting device cuts the waste paper in the upper space into smaller pieces. However, the shredded paper has gaps between it, occupying a large volume and making subsequent recycling inconvenient. Utility Model Content

[0020] Specific Implementation Example 1: Please refer to Figures 1-4 A raw material recycling and crushing device for yarn tube paper production includes a housing 1, a crushing roller 2, a cleaning nozzle 3, a guide plate 4, and a molding assembly 5.

[0021] A crushing inlet 11 is provided on the upper side of the housing 1, and a crushing roller 2 is disposed on one side of the crushing inlet 11. The crushing roller 2 and the crushing inlet 11 form a cutting space for crushing wood pulp fibers. A molding assembly 5 is disposed at the bottom of the housing 1 and below the cutting space. The molding assembly 5 includes a compression pusher plate 51 and a discharge pusher plate 54 symmetrically arranged on the left and right sides. In the working state, the compression pusher plates 51 on both sides move towards each other to compress the crushed wood pulp fibers.

[0022] A through-hole 12 is provided on the front side of the housing 1, and the discharge port 12 is located at the bottom of the housing 1. A push port 55 is provided on the opposite side of the discharge port 12. A discharge push plate 54 is provided at the push port 55, and one end of the discharge push plate 54 is fixedly connected to the output end of the discharge cylinder to push the wood pulp fibers toward the discharge port 12. When the wood pulp fibers are compressed, the discharge push plate 54 moves.

[0023] Compression ports 52 are respectively provided on the left and right sides of the housing 1. The size of the compression ports 52 matches that of the compression push plate 51 so that the compression push plate 51 can move horizontally along the compression ports 52. The compression cylinder 53 is fixedly installed on the outside of the housing 1, and the output end of the compression cylinder 53 is fixedly connected to the side of the compression push plate 51. The wood pulp fibers are squeezed inward by the mutual compression of the compression cylinders 53 on both sides.

[0024] Preferably, the volume height of the compressed wood pulp fiber does not exceed the height of the compression pusher plate 51.

[0025] In this embodiment, the crushing roller 2 includes two sets of independently rotating crushing roller bodies, which are arranged side by side. The crushing roller bodies are fixedly connected to the output end of an external rotating motor to drive each crushing roller body to rotate independently. The blades on the surfaces of the two sets of crushing roller bodies are staggered.

[0026] Inside the housing 1, a guide plate 4 is also provided. The guide plate 4 is located below the crushing roller 2 and includes an inclined end 41 and a vertical end 42. The upper end of the inclined end 41 is fixedly connected to the inner wall of the housing 1, and the inclined end 41 slopes downward toward the crushing roller 2. The upper end of the vertical end 42 is fixedly connected to the lower end of the inclined end 41, and the vertical end 42 and the side wall of the housing 1 form a material drop channel, so that the crushed wood pulp fibers fall to the bottom of the housing 1 through the material drop channel.

[0027] The cleaning nozzle 3 is fixedly mounted on the side wall of the housing 1, at the same horizontal level as the crushing roller 2, with its output end facing the crushing roller 2. The cleaning nozzle 3 is connected to an external air pump via an air circuit. Several cleaning nozzles 3 are arranged at equal intervals on the same straight line. It should be noted that controlling the directional airflow of the cleaning nozzle 3 via an air pump is a conventional existing technology, and its specific connection relationship and working principle will not be elaborated here.

[0028] Working principle:

[0029] The recycled paper tube raw material is placed into the crushing roller 2. The wood pulp fibers cut by the crushing roller 2 fall to the bottom of the box 1 through the guide plate 4 and the material drop channel formed by them. At the same time, the cleaning nozzle 3 sprays directional airflow to clean the residual wood pulp fibers on the crushing roller, ensuring the cleanliness of the crushing roller surface, and collecting as much raw material as possible to improve the crushing efficiency and quality. When the wood pulp fibers that have fallen to the bottom accumulate to a certain amount, the compression push plates 51 on both sides move towards each other to compress the wood pulp fibers. The discharge push plate 54 pushes the wood pulp fibers forward from the discharge port 12, which can realize the compaction and shaping of the crushed wood pulp fibers, reduce the volume of the crushed raw material, and facilitate subsequent recycling.
