Description

Technical Field

[0001] This utility model belongs to the field of rubber recycling technology, and specifically relates to a screening mechanism for a tire shredder. Background Technology

[0002] Tire shredders are mechanical devices specifically designed to process waste tires and transform them into reusable materials. They play an important role in resource recycling and environmental protection. The screening mechanism of a tire shredder is a key component of the crushing system, mainly used to classify the crushed tire particles according to size to ensure that the finished products meet the specifications of different application scenarios (such as rubber granules, rubber powder, etc.).

[0003] The existing tire shredder's screening mechanism feeds the shredded material into the screening cylinder via a feed hopper. The rotating screening cylinder and gravity then screen the shredded tire particles to meet subsequent processing requirements. However, because some of the shredded tire particles are small and lightweight, they have a short residence time on the screen surface after entering the screening cylinder. This results in some material not passing through the corresponding screen holes in time, which may affect the screening effect of the shredded tire particles. It is necessary for workers to pour the screened material back into the screening mechanism for secondary screening, which takes time and also affects the overall recycling and processing. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a screening mechanism for a tire shredder. This mechanism can reciprocate horizontally while driving the screening cylinder to tumble and rotate. In conjunction with the baffles installed on the inner wall of the screening cylinder, it can effectively enhance the screening effect of the screening cylinder while extending the material movement path, thus effectively ensuring the screening effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a screening mechanism for a tire shredder, including a screening box, with multiple evenly distributed partitions inside the screening box, a sliding rail in the middle of each partition, a movable ring slidably disposed inside each sliding rail, a screening cylinder disposed between the movable rings, a feed hopper on the upper side of the screening box, the feed hopper being installed in conjunction with the screening cylinder, an avoidance opening on the lower side of the screening box, a discharge pipe at the bottom of the screening cylinder cooperating with the avoidance opening, multiple first-hole openings on the side of the screening cylinder near the feed hopper, multiple second-hole openings in the middle of the screening cylinder, multiple third-hole openings on the side of the screening cylinder near the discharge pipe, multiple evenly distributed baffles on the inner wall of the screening cylinder, multiple discharge hoppers on the lower surface of the screening box, a support on the outer side of the screening box, multiple fixing plates on the lower surface of the support, each fixing plate having mounting holes.

[0006] As a further improvement of this utility model, the screening box is provided with symmetrically distributed guide rails inside, and rotating seats are slidably provided on the outer side of each guide rail. The rotating seats are rotatably connected to the screening cylinder. Buffer springs are provided between the two sides of the rotating seats and the screening box, and the buffer springs are sleeved on the outer side of the guide rails.

[0007] As a further improvement of this utility model, an adjusting screw is rotatably installed inside the screening box, and the adjusting screw is threadedly connected to the adjacent rotating seat. A second servo motor is installed on the outside of the screening box, and the output shaft of the second servo motor is fixed to the adjusting screw through a coupling. A gear is rotatably installed on the upper rotating seat through a rotating shaft. An external gear ring is fixedly sleeved on the outside of the screening cylinder, and the gear meshes with the external gear ring. A first servo motor is installed on the upper rotating seat, and the output shaft of the first servo motor is fixed to the rotating shaft through a coupling.

[0008] As a further improvement of this utility model, a control box is provided on the bracket, and both servo motor one and servo motor two are electrically connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the motor drives the shaft connected to it to rotate, and the gear drives the external gear ring that meshes with it to rotate, so that the external gear ring drives the screening cylinder to rotate, which in turn drives the screening cylinder and the baffles inside it to rotate quickly and evenly, thereby uniformly screening the material through rotation.

[0011] Secondly, the output shaft of the second servo motor drives the adjusting screw connected to it to rotate in both directions. Through the sliding relationship between the guide rail and the rotating seat, the screening cylinder in the rotation process is driven to reciprocate horizontally. The screening cylinder can be continuously moved horizontally back and forth, and the horizontal vibration of the screening cylinder can assist in the uniform screening of materials.

[0012] Third, the screen cylinder, which continuously sways horizontally during rotation, utilizes shaking, tumbling, and gravity to screen the crushed tire particles. The baffle plate extends the movement path of the tire particles that tumble downwards inside the screen cylinder, allowing the tire particles to be screened fully and efficiently.

[0013] Fourth, by tightening the bolts through the mounting holes on the fixed plate with external tools, the movement of the support caused by the vibration of the motor and screening during use can be effectively prevented, thus ensuring the fixed position of the support and the normal operation of the processing line.

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 3 , 4As shown, the screen includes a screening box 103. The screening box 103 has multiple evenly distributed partitions 201 inside. Each partition 201 has a sliding rail 202 in its center. Each sliding rail 202 has a movable ring 203 slidably mounted inside it. A screening cylinder 204 is positioned between the movable rings 203. A feed hopper 104 is located on the upper side of the screening box 103 and is installed in conjunction with the screening cylinder 204. A clearance opening 105 is provided on the lower side of the screening box 103. A discharge pipe that mates with the clearance opening 105 is located at the bottom of the screening cylinder 204. Multiple perforations 205 are provided on the side of the screening cylinder 204 near the feed hopper 104. The screening cylinder 204 has multiple perforations 206 in the middle and multiple perforations 207 on the side of the screening cylinder 204 near the discharge pipe. The inner wall of the screening cylinder 204 is provided with multiple evenly distributed baffles 208. The lower surface of the screening box 103 is provided with multiple discharge hoppers 106. The interior of the screening box 103 is provided with symmetrically distributed guide rails 209. Rotary seats 210 are slidably provided on the outer side of the guide rails 209. The rotating seats 210 are rotatably connected to the screening cylinder 204. Buffer springs 214 are provided between the two sides of the rotating seats 210 and the screening box 103. The buffer springs 214 are sleeved on the outer side of the guide rails 209.

[0022] like Figure 2 As shown, an adjusting screw 215 is rotatably installed inside the screening box 103. The adjusting screw 215 is threadedly connected to the adjacent rotating seat 210. A servo motor 216 is installed on the outside of the screening box 103. The output shaft of the servo motor 216 is fixed to the adjusting screw 215 by a coupling.

[0023] like Figure 2 , 3 As shown, the upper rotating seat 210 is equipped with a gear 212 that rotates through a rotating shaft. An external gear ring 211 is fixedly sleeved on the outer side of the screening cylinder 204. The gear 212 meshes with the external gear ring 211. The upper rotating seat 210 is equipped with a servo motor 213. The output shaft of the servo motor 213 is fixed to the rotating shaft through a coupling.

[0024] like Figure 1 , 2 As shown, a control box 301 is mounted on the bracket 101, and servo motor 1 213 and servo motor 216 are both electrically connected to the control box 301.

[0025] In use, the control box 301 controls the operation of servo motor 213 and servo motor 216, causing the output shaft of motor 213 to rotate, which in turn causes the shaft connected to it to rotate, causing gear 212 to drive the external gear ring 211 meshing with it to rotate, which in turn causes the external gear ring 211 to drive the screening cylinder 204 to rotate, which in turn causes the screening cylinder 204 to drive the multiple baffles 208 set on its inner wall to rotate.

[0026] The output shaft of servo motor 216 drives the adjusting screw 215 connected to it to rotate in both directions, causing the adjusting screw 215 to slide between the rotating seat 210 bolted to it and the guide rail 209. In turn, the sliding relationship between the guide rail 209 and the rotating seat 210 causes the screening cylinder 204 to reciprocate horizontally during the rotation process. When the screening cylinder 204 is moved horizontally, the feed hopper 104 does not contact the inner wall of the screening cylinder 204.

[0027] The crushed material from the tire shredder enters the screening cylinder 204 from the feed hopper 104. The tire particles are then screened by the horizontally swaying screening cylinder 204 during rotation, utilizing the effects of shaking, tumbling, and gravity. The downward-moving tire particles are graded and screened by the perforations 205, 206, and 206 on the inner wall of the screening cylinder 204. The screened material is discharged from the corresponding discharge hopper 106. The movement path of the downward-tumbling tire particles in the screening cylinder 204 is extended by the baffle 208, which allows the tire particles to be screened fully and efficiently.

[0028] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, a support 101 is provided on the outside of the screening box 103, and multiple fixing plates 102 are provided on the lower surface of the support 101. Each fixing plate 102 has mounting holes. In use, bolts are passed through the mounting holes on the fixing plates 102 and tightened with external tools, thereby firmly fixing the support 101 to the ground and effectively preventing the screening box 103 from easily moving during screening.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
