At the same time, when the feed amount is too much, the screening is insufficient, reducing the screening effect.

[0029] 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.

[0030] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "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 component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] like Figures 1 to 9 As shown, the utility model is a screening device for processing cable materials, comprising: a box body 1, a feeding mechanism for breaking up the cable materials and intermittently feeding them; a screening mechanism for screening the cable materials, an air blowing mechanism for blowing the screening mechanism to prevent blockage and remove dust from the cable materials; a driving member 2 for synchronously driving the feeding mechanism, the screening mechanism and the air blowing mechanism, and the driving member 2 is preferably a motor.

[0032] The unloading mechanism includes: a unloading hopper 5 inserted into the top of the box body 1, a crushing roller 3 symmetrically rotatably installed on the inner wall of the unloading hopper 5 and capable of breaking up the cable material, and a unloading roller 4 rotatably installed on the inner wall of the unloading hopper 5 and intermittently unloading the cable material. The outer edge of the unloading roller 4 is provided with a plurality of arc grooves for unloading, and the plurality of arc grooves are evenly distributed in a ring shape on the outer edge of the cylinder.

[0033] An appropriate amount of cable material is added into the lower hopper 5. A guide plate is fixedly installed on the inner wall of the lower hopper 5. The two guide plates are inclined toward between the two crushing rollers 3, so that the cable material can slide between the two crushing rollers 3, so as to facilitate the subsequent breaking up process. When the driving member 2 is started, the crushing roller 3 and the lower hopper 4 can be driven to rotate. Through the relative rotation of the two crushing rollers 3, the cable material in blocks can be broken up, so that the agglomerated granular materials cannot be screened, and the problem of feed blockage and screening efficiency is avoided. The broken up cable material falls into the inner cavity of the arc groove at the top of the lower hopper 4. When the lower hopper 4 rotates, several arc grooves can be rotated first for loading, and then rotated for unloading, so that the cable material can be fed intermittently, so that the problem of insufficient screening and reduced screening effect caused by excessive feed amount is avoided.

[0034] Through the above-mentioned mechanism, the device can realize the function of breaking up the agglomerated particles and feeding them intermittently, thus solving the problem that the agglomerated particles cannot be screened and easily cause feed blockage, thereby improving the screening efficiency. At the same time, the cable material can be fed intermittently, thus avoiding the problem of insufficient screening and reduced screening effect caused by excessive feed amount.

[0035] The screening mechanism includes: a material discharge opening 1 opened on the side wall of the box body 1, a screen plate 9 hingedly installed in the inner cavity of the material discharge opening 1, a cam 8 rotatably installed on the inner wall of the box body 1 and knocking the screen plate 9, and a reset spring 19 that drives the screen plate 9 to reset.

[0036] The broken up cable material falls to the top of the sieve plate 9 for screening. The cable material with larger particles slides through the top of the sieve plate 9 to the discharge opening for discharge, and the cable material with smaller particles falls through the sieve holes on the sieve plate 9. That is, the driving member 2 drives the cam 8 to rotate, and the cam 8 can knock on the sieve plate 9 when it rotates. When the cam 8 rotates to knock on the sieve plate 9, the sieve plate 9 drives the reset spring 19 to be compressed. When the cam 8 rotates and separates from the sieve plate 9, the sieve plate 9 is reset by the elastic force of the reset spring 19, so that the sieve plate 9 vibrates, thereby accelerating the sliding of the cable material on the top of the sieve plate 9 and improving the screening efficiency.

[0037] The blowing mechanism includes: a connecting pipe 12 arranged at the bottom of the sieve plate 9, a nozzle 13 inserted into the side wall of the connecting pipe 12, a dust removal box 15 fixedly installed on the top of the box body 1, an air pump 14 installed on one side of the dust removal box 15, a retractable hose inserted between the air pump 14 and the connecting pipe 12, an air guide pipe 16 inserted into the bottom of the dust removal box 15, an air suction hood 17 fixedly installed at the bottom end of the air guide pipe 16, and a swinging member that drives the connecting pipe 12 to swing.

[0038] While screening, start the air pump 14 to absorb the gas in the inner cavity of the dust removal box 15 and transport it to the inner cavity of the connecting pipe 12 through a retractable hose, and then spray it out through a number of nozzles 13. The sprayed high-pressure gas can clean the sub-screen holes of the sieve plate 9, so that the electrical material particles blocked in the sub-screen holes of the sieve plate 9 are blown out, avoiding the electrical material particles in the sub-screen holes causing the sieve plate 9 to be blocked and affecting the screening efficiency. Since the dust removal box 15, the air duct 16, the air suction hood 17 and the inner cavity of 1 are interconnected, the air in the inner cavity of the box body 1 enters the inner cavity of the dust removal box 15 through the air suction hood 17 and the air duct 16, and is then sucked out by the air pump 14, so that the air in the inner cavity of the box body 1 forms a circulating flow.

[0039] Since the high-pressure gas can blow the dust attached to the surface of the cable material particles upwards during the cleaning process of the sub-screening holes of the sieve plate 9, the dust floating in the inner cavity of the box body 1 will enter the inner cavity of the dust removal box 15 with the airflow for collection, thereby having a certain dust removal effect on the cable material, improving the practicability of the device, and avoiding the clogging of the sub-screening holes of the sieve plate 9 by dust, thereby improving the efficiency of sub-screening.

[0040] It should be added here that a filter screen that is easy to replace can be provided in the inner cavity of the dust removal box 15 so that dust is retained in the inner cavity of the dust removal box 15. The high-pressure gas ejected by the nozzle 13 is clean gas, which will not cause pollution to the cable material screened to the bottom of the sieve plate 9, thereby improving the screening effect.

[0041] Through the above-mentioned mechanism, on the one hand, the sub-screening holes of the sieve plate 9 can be cleaned so that the electric material particles blocked in the sub-screening holes of the sieve plate 9 can be blown out, thereby avoiding the electric material particles in the sub-screening holes causing the sieve plate 9 to be blocked and affecting the sub-screening efficiency. On the other hand, it can play a certain dust removal role on the cable material, thereby improving the practicability of the device, and avoiding the clogging of the sub-screening holes of the sieve plate 9 by dust, thereby improving the sub-screening efficiency.

[0042] The swinging member includes a linkage plate 10 hingedly mounted on the inner wall of the box 1 , and a linkage spring 11 fixedly mounted between the outer side of the linkage plate 10 and the inner wall of the box 1 ; the other side of the linkage plate 10 is fixedly mounted on the outer edge of the connecting pipe 12 .

[0043] When the cam 8 rotates and strikes the sieve plate 9, it also strikes the linkage plate 10. When the cam 8 rotates and strikes the linkage plate 10, the linkage plate 10 drives the linkage spring 11 to compress. When the cam 8 rotates and separates from the linkage plate 10, the elastic force of the linkage spring 11 drives the linkage plate 10 to reset, so that the linkage plate 10 swings, and the connecting tube 12 is driven to swing by the linkage plate 10. The swing of the connecting tube 12 expands the blowing range, so that the entire sieve plate 9 can be fully blown, and the electrical material particles blocked in the sub-sieve holes of the sieve plate 9 are blown out, avoiding the electrical material particles in the sub-sieve holes causing the sieve plate 9 to be blocked, affecting the screening efficiency.

[0044] The driving member 2 includes: a motor for driving the crushing rollers 3 to rotate, a linkage member 1 6 for linking the two crushing rollers 3, and a linkage member 2 7 for linking the crushing rollers 3, the unloading roller 4, and the cam 8.

[0045] The linkage member 6 is preferably a transmission gear transmission that meshes with each other, and the relative rotation of the two transmission gears can drive the relative rotation of the two crushing rollers 3.

[0046] The linkage member 2 7 is preferably driven by a belt and a pulley. Through the transmission of the belt and the pulley, the crushing roller 3, the feeding roller 4 and the cam 8 can be rotated simultaneously, so that the device can simultaneously break up, intermittently feed and screen the cable material, which not only realizes the function of breaking up the agglomerated particles and feeding them intermittently, but also solves the problem that the agglomerated particles cannot be screened and easily cause feed blockage, and avoids the problem that the screening is insufficient and the screening effect is reduced when the feed amount is too much, and simplifies the process flow, does not require multiple equipment, and reduces production costs.

[0047] A second discharge opening is also provided on the side wall of the box 1, and a guide block 18 is fixedly installed at the bottom of the inner cavity of the box 1. The cable material with smaller particles screened through the screen holes on the screen plate 9 falls to the top of the guide block 18. Since the top of the guide block 18 is an inclined surface, the cable material can be guided to the second discharge opening, thereby facilitating the discharge of the cable material with smaller particles and improving the discharge efficiency.

[0048] Working principle: When in use, add an appropriate amount of cable material into the discharge hopper 5. When the driving part 2 is started, the crushing roller 3 and the discharge roller 4 can be driven to rotate. Through the relative rotation of the two crushing rollers 3, the cable material in blocks can be crushed and broken up, and the broken up cable material falls into the inner cavity of the arc groove at the top of the discharge roller 4. When the discharge roller 4 rotates, the cable material can be intermittently fed, and the broken up cable material falls to the top of the screen plate 9 for screening. While screening, start the air pump 14 to absorb the gas in the inner cavity of the dust removal box 15, and transport it to the inner cavity of the connecting pipe 12 through a retractable hose, and then spray it through a number of nozzles 13. The ejected high-pressure gas can clean the sub-screen holes of the screen plate 9. In the process of cleaning the sub-screen holes of the screen plate 9, the high-pressure gas can blow the dust attached to the surface of the cable material particles upwards, and the dust floating in the inner cavity of the box body 1 will enter the inner cavity of the dust removal box 15 with the airflow for collection.

The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
