Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a raw material crusher for cable materials. Background Art

[0002] When producing cables, additional protective layers are required to enhance their wear resistance and resistance to external damage. In this step, it can be done by braiding or sheathing, usually using materials such as polyester and polypropylene for braiding, or using materials such as polyvinyl chloride and rubber for sheathing. When making the sheath, polyvinyl chloride and rubber need to be crushed and then made through an extruder.

[0003] The patent with application number CN202321428172.X relates to the field of cable raw material technology, including a crushing box, a feeding box, a rotating shaft, which is rotatably connected between the front and rear sides of the crushing box; a crushing roller, which is fixedly connected to the surface of the rotating shaft; and a feeding box, which is fixedly connected to the upper end of the crushing box, and discloses a crushing device for the production of PVC cable raw materials. The crushing device for the production of PVC cable raw materials drives the gears to rotate through the provided driving motor, and the engagement between the gears can drive the rotating shaft to drive the crushing roller to rotate, so as to crush the cable raw materials, and the cable raw materials that are not completely crushed can be blocked by the filter plate, and the cable raw materials blocked by the filter plate can be sucked in by the provided fan, and then transported to the feeding box through the outlet pipe for secondary crushing until they are crushed to the specified size, without the need for the staff to manually take out the incompletely crushed raw materials for manual secondary crushing, which saves manpower and improves the crushing quality at the same time.

[0004] This patent uses a filter plate to block the cable raw materials that are not completely crushed, but the filter plate has a low filtering efficiency for the raw materials. When in use, material piles are likely to appear on the surface of the filter plate. At this time, the fan may inhale the crushed raw materials, affecting the efficiency of use.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0023] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] like Figures 1 to 5As shown, the utility model is a raw material crusher for cable materials, comprising: a crushing box 1, a crushing roller 4 for crushing the raw material, the crushing roller 4 is driven by a motor to rotate to crush the raw material, and a filter screen 7 for filtering the crushed raw material, a cross fixing plate 6 fixedly installed on the filter screen 7, the cross fixing plate 6 is the skeleton of the filter screen 7, a screening component 5 for driving the filter screen 7 to move, and a feeding component 8 for preventing the crushing box 1 from being blocked; and also comprising: a feed port 2 opened on the crushing box 1, a The air outlet duct 3 draws the raw materials accumulated on the surface of the filter screen 7 to the feed port 2 for re-crushing and the crushing roller 4 for crushing the raw materials. The crushing box 1 is fixedly installed with a lower hopper 9. The raw materials are added to the inside of the crushing box 1 through the feed port 2, and fall onto the surface of the filter screen 7 after being crushed by the crushing roller 4. The filter screen 7 is driven to move back and forth by the screening component 5, so that the raw materials on the surface of the filter screen 7 fall downward into the lower hopper 9 and are discharged outward through the lower hopper 9. At the same time, the lower hopper 8 moves back and forth to prevent the raw materials from accumulating inside the lower hopper 9.

[0025] The screening assembly 5 includes: a gear 1 51, a gear 2 52 driven by the gear 1 51 when rotating, a convex rod 53 fixedly connected to the gear 1 51, a semi-gear 54 sleeved on the convex rod 53, and a rack 55 meshed with the semi-gear 54, wherein the rack 55 is fixedly connected to the cross fixing plate 6, and the crushing roller 4 rotates to drive the gear 2 52 to rotate through the gear 1 51, and due to the meshing of the gear 1 51 and the gear 2 52, the rotation directions of the two groups of crushing rollers 4 are opposite, and the crushing effect is better. When the gear 1 51 rotates, the convex rod 53 performs a circular motion, and the semi-gear 54 is rotatably connected to the crushing box 1 through the connecting shaft, so that the convex rod 53 drives the semi-gear 54 to swing back and forth when moving, and the semi-gear 54 is meshed with the rack 55, so that the rack 55 moves back and forth and drives the filter screen 7 to move back and forth, so that the filter screen 7 is more efficient in screening the raw materials.

[0026] The material discharging assembly 8 comprises: a push rod 81, a push rod 81 fixedly mounted on the cross fixing plate 6, a push plate 82 abutting against the push rod 81, and a reset rod 83 driving the material discharging plate to reset. The filter screen 7 drives the push rod 81 to move back and forth and abuts against the push plate 82, so that the push plate 82 rotates and swings through the reset rod 83. If the material inside the lower hopper 9 is accumulated and cannot fall, the push plate 82 will destroy the structure of the material accumulation when it moves, avoiding its blockage and making it impossible to discharge the material. The reset rod 83 is composed of a rotating sleeve 831 fixedly connected to the push plate 82, a spring 832 fixedly connected to the rotating sleeve 831, and a fixed rod 833 fixedly connected to the other end of the spring 832. The fixed rod 833 is fixedly connected to the lower hopper 9. The push plate 82 drives the rotating sleeve 831 to rotate and causes the spring 832 to deform under force. When the push rod 81 stops pushing the push plate 82, the spring 832 drives the push plate 82 to reset, and the practical effect is better.

[0027] Working principle:

[0028] The crushing roller 4 rotates through the gear 1 51 to drive the gear 2 52 to rotate. When the gear 1 51 rotates, the protruding rod 53 makes a circular motion accordingly, so that the protruding rod 53 drives the half gear 54 to swing back and forth during the movement, and the half gear 54 is meshed with the rack 55, so that the rack 55 moves back and forth and drives the filter screen 7 to move back and forth. At the same time, the filter screen 7 drives the push rod 81 to move back and forth and abuts against the push plate 82, so that the push plate 82 rotates and swings through the reset rod 83 to avoid blockage of the lower hopper 9. The reset rod 83 is provided with a spring 832 to drive the push plate 82 to reset. The raw materials that cannot be discharged on the surface of the filter screen 7 are sucked into the feed port 2 through the fan and added into the crushing box 1 for crushing again.
