Description

Technical Field

[0001] This utility model relates to the field of masterbatch sieving, and more specifically, it relates to a vibrating screen for removing impurities from wear-resistant cable masterbatch. Background Technology

[0002] Wear-resistant cable masterbatch is a masterbatch (i.e., base material) specifically used to manufacture cable materials with excellent wear resistance, oil resistance, and chemical corrosion resistance. It is usually made of high-performance polymer system and additives. Its purpose is to improve the wear resistance and service life of the cable outer layer. It is mainly used for cable sheaths and outer sheaths, industrial cables and cables for special environments. It has high wear resistance, good mechanical properties, excellent oil resistance, chemical corrosion resistance and good processing performance.

[0003] For example, Chinese Patent Publication No. CN218637882U discloses a masterbatch sorting vibrating screen, which includes a base, a screening mechanism, and a vibration mechanism. The base has symmetrically arranged vertical plates on its upper right side, with a sorting box rotatably connected between the two plates via a pin. A feed hopper is located at the upper end of the sorting box. The screening mechanism includes slide rails, screening plates, and screening holes. The slide rails are respectively arranged inside the sorting box, and a screening plate is slidably connected between each pair of horizontally corresponding slide rails. Screening holes are opened inside the screening plates, with the diameter of the screening holes decreasing from top to bottom. The vibration mechanism is located at the upper end of the base. A discharge hopper is located at the right end of the sorting box, corresponding to the left and right positions of the screening plates. This masterbatch sorting vibrating screen facilitates the removal of the screening plates for maintenance and replacement, has high screening efficiency, is simple to operate, convenient to use, and has a wide range of applications.

[0004] In the vibrating screen described above, it is inevitable that some masterbatch that matches the size of the screening holes will get stuck in the screening holes. After the screening holes are blocked, the screening efficiency will be severely affected. Therefore, it is necessary to clean the masterbatch blocking the screening holes regularly. The common cleaning method is usually to manually remove the blockages from the screening holes by hand or with a fine brush or thin wire. The cleaning process is relatively time-consuming, which will increase downtime and reduce the working efficiency of the equipment.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a vibrating screen for removing impurities from wear-resistant cable masterbatch. By pushing and pulling the connecting column and connecting plate with the push-pull lever, the connecting plate squeezes the return spring and pulls the expanded-hole screen to move. The mesh of the expanded-hole screen and the mesh of the through screen will overlap, increasing the mesh range. The toothed plate moves with the expanded-hole screen and drives the striking arm through gears to strike the expanded-hole screen, helping to discharge the masterbatch in the mesh. The cleaning method is quick and convenient, effectively reducing downtime and improving equipment efficiency.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vibrating screen for removing impurities from wear-resistant cable masterbatch, comprising: a sieve shell, wherein at least two sieve screens are provided on the inner surface of the sieve shell;

[0008] A material clearing assembly is used to remove the masterbatch stuck in the mesh of the sieve.

[0009] By adopting the above technical solution, the connecting column and connecting plate are pulled by pushing and pulling the lever. The connecting plate squeezes the return spring and pulls the enlarged hole screen to move. The mesh of the enlarged hole screen and the mesh of the sieve will overlap, increasing the mesh range. The toothed plate moves with the enlarged hole screen and drives the knocking arm through the gear to knock the enlarged hole screen, helping the masterbatch in the mesh to be discharged. By repeatedly pulling the push and pull lever several times, the masterbatch in the mesh can be cleaned. The cleaning method is quick and convenient, effectively reducing downtime and improving the working efficiency of the equipment.

[0010] The present invention is further configured such that: the push-pull reset component includes a hidden shell fixed to the outer surface of the sieve shell and a connecting column fixed to the connecting plate, one end of the connecting column extends to the outside of the hidden shell and is fixed with a push-pull handle, and a reset spring is provided between the connecting plate and the inner wall of the hidden shell.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0024] like Figure 1-4 As shown, a vibrating screen for removing impurities from wear-resistant cable masterbatch includes a screening shell 1 and a cleaning assembly 3. At least two screening screens 2 are fixed on the inner surface of the screening shell 1. The two screening screens 2 are distributed vertically, and the diameter of the mesh size decreases from top to bottom. A discharge nozzle 4 is provided on the outer surface of the screening shell 1. The discharge nozzle 4 is located at the position corresponding to the screening screen 2 and at the bottom of the inner wall of the screening shell 1, and is used to discharge the screened masterbatch. A feed hopper 5 is fixed on the top side of the screening shell 1 away from the discharge nozzle 4. A support assembly 6 is provided at the bottom of the screening shell 1. The support assembly 6 includes a support frame 61. At least four support columns 62 are fixed on the top of the support frame 61, respectively located at the four corners of the bottom of the screening shell 1. A strong spring 63 is fixed to one end of the support column 62. The strong spring 63 is fixed to the bottom of the screening shell 1 by a limiting column. A servo motor 64 is fixed to the top of the support frame 61 by a connecting frame. A cam 65 is fixed to one end of the output shaft of the servo motor 64. The cam 65 is located below the screening shell 1.

[0025] The material cleaning component 3 is used to remove the masterbatch stuck in the mesh of the screen 2. The material cleaning component 3 includes an enlarged hole screen 31 set at the bottom of the screen 2. An L-shaped anti-fall plate 32 is fixed on the enlarged hole screen 31. The L-shaped anti-fall plate 32 extends to the outside of the screen shell 1. A connecting plate 33 is fixed on the enlarged hole screen 31 at a position opposite to the L-shaped anti-fall plate 32. The cross-section of the connecting plate 33 is T-shaped. The connecting plate 33 extends to the outside of the screen shell 1. A push-pull reset component is provided on the outer surface of the connecting plate 33.

[0026] The push-pull reset component includes a hidden shell 34 fixed to the outer surface of the sieve shell 1 and at least two connecting posts 35 fixed to the connecting plate 33. One end of the connecting post 35 extends to the outside of the hidden shell 34 and is fixed with a push-pull handle 36. At least three reset springs 37 are fixed between the connecting plate 33 and the inner wall of the hidden shell 34. When the reset springs 37 are at their original length and no external force is applied, the connecting plate 33 is attached to the outer surface of the sieve shell 1. At this time, the interlaced mesh diameter between the enlarged mesh 31 and the sieve 2 is the size used when the masterbatch is sieved.

[0027] The bottom of the enlarged-hole screen 31 is provided with at least two grooves 38. The cleaning assembly 3 also includes a striking element provided at the bottom of the enlarged-hole screen 31. The number of striking elements corresponds to the number of grooves 38. The striking element includes a toothed plate 39 fixed to the inner surface of the groove 38 and a striking arm 310 rotating on the inner surface of the screen shell 1. One end of the striking arm 310 is provided with a groove 311. A gear 312 is fixed on the inner side of the groove 311. The gear 312 meshes with the toothed surface of the toothed plate 39.

[0028] In use, the masterbatch is poured into the feed hopper 5, and the servo motor 64 is started. The servo motor 64 drives the cam 65 to rotate. One end of the cam 65 repeatedly strikes the sieve shell 1, causing the sieve shell 1 to shake. This screens the masterbatch falling onto the sieve screen 2. Masterbatch larger than the mesh diameter of the sieve screen 2 will be discharged from the discharge nozzle 4. Masterbatch smaller than the mesh diameter of the sieve screen 2 and impurities will fall to the next sieve screen 2 for further screening. This separates the masterbatch from the fine impurities. The screened masterbatch and impurities will be discharged from different discharge nozzles 4.

[0029] After screening, the connecting column 35 and connecting plate 33 can be pulled by the push-pull lever 36. The connecting column 35 will cause the connecting plate 33 to squeeze the return spring 37. When the connecting plate 33 moves, it will pull the enlarged screen 31 to move. The enlarged screen 31 will move the mesh to the position below the mesh of the screen 2, increasing the mesh range when the two are stacked. As the enlarged screen 31 moves, the toothed plate 39 will move with it, thereby driving the gear 312 to rotate. The gear 312 will then drive the striking arm 310 to deflect, striking the enlarged screen 3. 1. The push-pull lever 36 helps the masterbatch stuck in the mesh of the screen 2 to fall out of the mesh. After releasing the push-pull lever 36, the expanded mesh 31 will be reset by the elastic force of the reset spring 37, thereby resetting the toothed plate 39. The toothed plate 39 drives the knocking arm 310 to deflect and reset through the gear 312. If the masterbatch or impurities blocked in the mesh are not completely discharged after pulling the push-pull lever 36 once, the push-pull lever 36 can be pulled several times. It is quick and convenient to clean the masterbatch blocked in the mesh, effectively reducing downtime and improving the working efficiency of the equipment.
