Description

Technical Field

[0001] This utility model relates to the field of material screening technology, specifically to a butyl reclaimed rubber particle screening device. Background Technology

[0002] The butyl reclaimed rubber particle screening device is a device used for particle size classification and impurity separation of butyl reclaimed rubber particles. It uses different physical principles to classify butyl reclaimed rubber particles according to particle size or other characteristics to meet the particle size requirements of different production processes, while removing any impurities that may be present, thereby improving the quality and purity of the reclaimed rubber particles.

[0003] In the prior art, such as the recycled rubber powder screening device disclosed in CN216026107U, static electricity is removed from the rubber powder by an electrostatic eliminator plate to prevent the rubber powder from agglomerating due to static electricity; an electromagnet removes iron filings from the rubber powder to improve the quality of the recycled rubber powder; and two robotic arms drive the electromagnet to work alternately to improve the efficiency of iron filings removal.

[0004] The device uses a robotic arm to carry an electromagnet to attract iron filings. This method of removing iron filings requires the robotic arm to continuously and accurately scan the surface of the conveyor belt to attract the iron filings. This places high demands on the movement accuracy of the robotic arm, and the robotic arm suffers severe wear in this working environment. This increases the cost of using the device and the movement and cleaning efficiency of the robotic arm is low. Therefore, we propose a butyl reclaimed rubber particle screening device. Summary of the Invention

[0005] One of the technical problems this application aims to solve is that using a robotic arm to carry an electromagnet to attract iron filings increases the cost of the device and results in low cleaning efficiency due to the robotic arm's movement.

[0006] To solve the above-mentioned technical problems, this application provides a butyl reclaimed rubber particle screening device, including a crusher, an iron removal component for removing rust is provided inside the crusher, a screening machine is provided on the right side inside the crusher, and a motor is provided at the front of the crusher.

[0007] Preferably, the iron removal component includes a fixed plate disposed inside the crusher. Both ends of the fixed plate are rotatably connected to a synchronous shaft. A magnet is disposed on the outer periphery of the synchronous shaft on the right side. A synchronous belt is sleeved on the outer periphery of the synchronous shaft on the left side and multiple magnets. A cleaning component for cleaning the surface of the synchronous belt is disposed at the lower part of the fixed plate. The front end of the synchronous shaft on the left side is disposed at the drive end of the motor.

[0008] Preferably, the cleaning component includes a cleaning shaft rotatably connected to the lower part of the fixed plate, a protective shell is provided on the rear side of the fixed plate, and a second gear and a first gear are rotatably connected inside the protective shell. The second gear and the first gear mesh with each other. A plurality of evenly distributed bristles are provided on the outer periphery of the cleaning shaft, and the rear end of the left-side synchronous shaft is located in the middle of the second gear.

[0009] Preferably, the surface of the synchronous belt is provided with a plurality of evenly distributed synchronous grooves, and the rotation direction of the synchronous grooves and the synchronous belt is 45 degrees.

[0010] Preferably, the bristles are arranged in a spiral shape and abut against the lower part of the fixing plate.

[0011] Preferably, the front end of the synchronous shaft is threadedly connected to a fastening plate, the inner wall of the magnet is provided with a locking block, two mounting plates are provided on the side of the locking block near the synchronous shaft, and multiple evenly distributed slots are opened on the outer periphery of the synchronous shaft, with the locking block abutting against the inside of the slots.

[0012] Preferably, both the card block and the card slot are L-shaped.

[0013] This utility model has at least the following beneficial effects: 1. The motor drives the synchronous shaft to rotate. Through the cooperation of two synchronous shafts and multiple magnets, the synchronous belt can be rotated to drive the material to flow downward. When the material moves downward to the vicinity of the magnet, the magnet can attract the iron filings flowing on the surface of the synchronous belt. The material slides down into the interior of the screening machine due to inertia. The iron filings will be attracted by the magnet to the surface of the synchronous belt and collected by the synchronous groove. When the iron filings are carried away from the magnet by the synchronous belt, the magnetic force on the iron filings inside the synchronous groove decreases. Under the action of gravity, the iron filings fall down and leave the synchronous belt, thereby realizing the function of removing iron filings.

[0014] 2. When the synchronous shaft rotates, it can drive gear two and gear one to rotate. The rotation of gear one drives the cleaning shaft and brush to rotate. When the brush rotates, it can wash the surface of the synchronous belt and synchronous groove, brushing away the iron filings remaining on the surface of the synchronous belt. This can clean the iron filings that are attracted to the surface of the synchronous belt due to static electricity. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a butyl reclaimed rubber particle screening device, including a crusher 1, an iron removal component 4 for removing rust is provided inside the crusher 1, a screening machine 2 is provided on the right side inside the crusher 1, and a motor 3 is provided at the front of the crusher 1.

[0019] Furthermore, the iron removal component 4 includes a fixed plate 41 installed inside the crusher 1. Both the left and right ends of the fixed plate 41 are rotatably connected to a synchronous shaft 42. A magnet 43 is installed on the outer periphery of the right synchronous shaft 42. A synchronous belt 44 is sleeved on the outer periphery of the left synchronous shaft 42 and multiple magnets 43. A cleaning component 5 for cleaning the surface of the synchronous belt 44 is installed at the lower part of the fixed plate 41. The front end of the left synchronous shaft 42 is installed at the drive end of the motor 3. The fixing plate 41 can fix two synchronous shafts 42. The synchronous shaft 42 on the right can drive multiple magnets 43 to rotate. The magnets 43 are used to attract iron filings. The synchronous belt 44 can slide on the outer periphery of the synchronous shaft 42. The material mixed with iron filings can be carried by the synchronous belt 44 through the iron removal step and then enter the interior of the screening machine 2.

[0020] Furthermore, the cleaning component 5 includes a cleaning shaft 51 rotatably connected to the lower part of the fixed plate 41. A protective shell 55 is provided on the rear side of the fixed plate 41. Gear 2 54 and gear 1 53 are rotatably connected inside the protective shell 55. Gear 2 54 and gear 1 53 mesh with each other. Multiple evenly distributed bristles 52 are provided on the outer periphery of the cleaning shaft 51. The rear end of the left synchronous shaft 42 is located in the middle of gear 2 54. The cleaning shaft 51 is used to drive multiple brush bristles 52 to rotate. The protective shell 55 can protect the internal gears 2 54 and 1 53 to prevent foreign objects from entering between them. Gears 2 54 and 1 53 can transmit power. One rotation of gear 2 54 can make gear 1 53 rotate several times. The synchronous shaft 42 can drive gear 2 54 to rotate. Gear 2 54 drives gear 1 53 and cleaning shaft 51 to rotate. The cleaning shaft 51 drives the brush bristles 52 to rotate and brush the surface of the synchronous belt 44.

[0021] Furthermore, the surface of the synchronous belt 44 is provided with a plurality of evenly distributed synchronous grooves 45, and the rotation direction of the synchronous grooves 45 and the synchronous belt 44 is forty-five degrees. The timing groove 45 can accommodate iron filings and can increase the friction between the timing belt 44 and the recycled material.

[0022] Furthermore, the multiple bristles 52 are arranged in a spiral shape, and the bristles 52 abut against the lower part of the fixing plate 41; By arranging the bristles 52, the bristles 52 can be rotated to sweep the iron filings and push them to one side of the timing belt 44, thereby increasing the efficiency of cleaning the timing groove 45.

[0023] When the device is working, it can crush the recycled material and then let it flow downward into the upper part of the synchronous belt 44. The motor 3 drives the synchronous shaft 42 to rotate. Through the cooperation of the two synchronous shafts 42 and multiple magnets 43, the synchronous belt 44 can be rotated to drive the material to flow downward. When the material moves downward to the vicinity of the magnet 43, the magnet 43 can attract the iron filings flowing on the surface of the synchronous belt 44. When the synchronous belt 44 rotates, the material can slide down into the interior of the screening machine 2 due to inertia. The iron filings will be attracted to the surface of the synchronous belt 44 by the magnet 43 and concentrated by the synchronous groove 45. When the iron filings are carried away from the magnet 43 by the synchronous belt 44, the magnetic force on the iron filings inside the synchronous groove 45 decreases. The iron filings fall down and leave the synchronous belt 44 under the action of gravity. When the synchronous shaft 42 rotates, it can drive the gear 2 54 and the gear 1 53 to rotate. The rotation of the gear 1 53 drives the cleaning shaft 51 and the brush 52 to rotate. When the brush 52 rotates, it can wash the surface of the synchronous belt 44 and the synchronous groove 45, brushing away the iron filings remaining on the surface of the synchronous belt 44.

[0024] Example 2: Please refer to Figure 5 Based on Embodiment 1, this utility model provides another technical solution: a fastening plate 434 is threadedly connected to the front end of the synchronous shaft 42, a locking block 432 is provided on the inner wall of the magnet 43, two mounting plates 431 are provided on the side of the locking block 432 near the synchronous shaft 42, and multiple evenly distributed slots 433 are opened on the outer periphery of the synchronous shaft 42, with the locking block 432 abutting against the inside of the slots 433.

[0025] Furthermore, both the card block 432 and the card slot 433 are L-shaped; Mounting plate 431 can carry and move the locking blocks 432 and magnets 43. By inserting the two locking blocks 432 into the slots 433, and then pushing mounting plate 431 to make the locking blocks 432 lock into the slots 433, and then rotating fastening plate 434 to push and squeeze mounting plate 431, the pressure between the two increases. This allows magnets 43 to be removed and replaced when their magnetic force weakens, reducing the overall cost of replacing synchronous shaft 42 and multiple magnets 43.
