Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, and in particular to a rubber pelletizer. Background Technology

[0002] A rubber pelletizer is a mechanical device that can cut waste rubber or rubber raw materials (such as rubber blocks, rubber scraps, waste tire inner tubes, etc.) into fine pellets. It is widely used in rubber recycling, reclaimed rubber production, sports field material manufacturing and other fields.

[0003] After the rubber is granulated, the particles are of different sizes and may stick together. Therefore, they need to be screened. The qualified particles fall to the bottom of the pelletizer and are then conveyed to the next processing step. The unqualified particles are conveyed to the feed inlet at the top of the pelletizer for repeated crushing and pelletizing.

[0004] However, in this prior art, as unqualified rubber particles fall onto the screen and accumulate on the screen, the screen holes are blocked, making it difficult for qualified particles to pass through the screen holes quickly and fall to the bottom of the pelletizer, resulting in a decrease in pelletizing efficiency.

[0005] Therefore, it is necessary to solve the above problems by using a rubber processing pelletizer. Utility Model Content

[0006] The purpose of this invention is to provide a rubber pelletizer to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rubber processing pelletizer, comprising a pelletizing box fixedly mounted on a support frame, a feed inlet at the top of the pelletizing box, a pelletizing assembly on the pelletizing box, a screening plate located below the pelletizing assembly inside the pelletizing box, vibration assemblies at the four corners of the screening plate, a dispensing port on one side of the pelletizing box, a transmission assembly connected to the outside of the dispensing port, and a linkage assembly for driving the vibration assembly at the bottom of the transmission assembly; The linkage component includes a drive wheel fixedly mounted on the transmission component and a driven wheel rotatably mounted on the side of the pelletizing box. A transmission belt is wound around the circumference of the drive wheel and the driven wheel, and a lifting column is provided on the driven wheel. It also includes a central control unit, which is electrically connected to both the pelletizing assembly and the conveying assembly.

[0008] Preferably, the transmission assembly includes a transmission cylinder fixedly disposed on one side of the pelletizing box, the inlet at the bottom of the transmission cylinder being connected to the distribution port, the outlet at the top being located above the inlet, and a spiral blade being rotatably disposed inside the transmission cylinder.

[0009] Preferably, a transmission motor is fixedly installed on the support frame, the output shaft of the transmission motor is fixedly connected to the bottom end of the spiral blade, and a fixing member is provided in the middle of the outer side of the transmission cylinder, one end of the fixing member is fixedly installed on the pelletizing box.

[0010] Preferably, the vibration assembly includes a fixed plate fixedly installed on the inner side of the pelletizing box, a limiting post fixedly provided on the top surface of the fixed plate, and the screening plate slidably sleeved on the limiting post.

[0011] Preferably, a vibration spring is sleeved on the outside of the limiting post, with the top end of the vibration spring fixedly connected to the bottom surface of the screening plate and the bottom end fixedly connected to the top surface of the fixing plate.

[0012] Preferably, the pelletizing assembly includes a pelletizing roller rotatably disposed at the top of the pelletizing box, and a pelletizing motor is mounted on one side of the pelletizing box, the output shaft of the pelletizing motor being connected to one end of the pelletizing roller.

[0013] Preferably, the screening plate is configured as an inclined plate, with the bottom end of the inclined surface of the screening plate located below the material distribution port.

[0014] Preferably, the passive wheel is positioned below the feed inlet, and a notch is provided on the side of the pelletizing box for the lifting column to pass through.

[0015] The technical effects and advantages of this utility model are as follows: 1. In this utility model, by setting a transmission component, a vibration component, and a linkage component, during the operation of the transmission component, the linkage component cooperates with the vibration component to vibrate the screening plate, so that the screening plate vibrates and screens the rubber particles. Qualified rubber particles fall from the screen holes, while unqualified rubber particles roll towards the feed inlet with the vibration, and are then transported again by the transmission component to the feed inlet for secondary pelleting. This avoids the unqualified rubber particles from accumulating and blocking the screen holes, and allows qualified rubber particles to pass through the screen holes quickly, thereby improving pelleting efficiency.

[0016] 2. In this utility model, by setting up an active wheel, a passive wheel, and a lifting column, when the transmission component is running, it drives the active wheel to rotate, which in turn drives the passive wheel to rotate. This causes the lifting column to repeatedly lift the screening plate, causing the screening plate to vibrate and rapidly screen the rubber particles. While accelerating the fall of qualified rubber particles, it sends unqualified rubber particles to the transmission component for secondary pelletizing. This prevents unqualified rubber particles from accumulating on the screening plate and clogging the screen holes, and promotes the rapid fall of qualified rubber particles for subsequent production steps, thereby improving pelletizing efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] To address the problem that defective rubber granules accumulate on the screen, blocking the screen openings and hindering the rapid passage of qualified granules to the bottom of the pelletizer, thus reducing pelletizing efficiency, the following embodiments are proposed.

[0021] This utility model provides, for example Figures 1 to 5The rubber pelletizer shown includes a pelletizing box 1 fixedly mounted on a support frame 8. A discharge port is provided at the bottom of the pelletizing box 1, through which workers can discharge rubber pellets, which are then transported to the next step. A feed inlet 3 is provided at the top of the pelletizing box 1. A pelletizing assembly 4 is mounted on the pelletizing box 1. A screening plate 5 is located below the pelletizing assembly 4 inside the pelletizing box 1. Vibration components 6 are located at the four corners of the screening plate 5. A distribution port 9 is provided on one side of the pelletizing box 1. A transmission assembly 2 is connected to the outside of the distribution port 9. A linkage component 7 for driving the vibration components 6 is located at the bottom of the transmission assembly 2. The screening plate 5 is an inclined plate, with the bottom end of the inclined surface of the screening plate 5 located below the distribution port 9. The pelletizer also includes a main control panel, which is electrically connected to both the pelletizing assembly 4 and the transmission assembly 2. The pelletizing assembly 4 includes a pelletizing roller 402 rotatably mounted at the top of the pelletizing box 1. A pelletizing motor 401 is mounted on one side of the pelletizing box 1, and the output shaft of the pelletizing motor 401 is connected to one end of the pelletizing roller 402. The main control panel can control the switching of the pelletizing motor 401 and the transmission motor 204.

[0022] In operation, the operator starts the pelletizing motor 401 and the transmission motor 204 via the main control panel. The pelletizing motor 401 drives the pelletizing rollers 402 to rotate, and the rubber raw material is fed into the pelletizing box 1 through the feed inlet 3. The rubber raw material passes between the pelletizing rollers 402 and is cut into rubber pellets. The rubber pellets fall onto the screening plate 5. Rubber pellets of the correct size pass through the sieve holes on the screening plate 5 and fall to the bottom of the pelletizing box 1.

[0023] By setting up a transmission component 2, a vibration component 6, and a linkage component 7, during the operation of the transmission component 2, the linkage component 7 works in conjunction with the vibration component 6 to vibrate the screening plate 5, causing the screening plate 5 to vibrate and screen the rubber particles. Qualified rubber particles fall through the screen holes, while unqualified rubber particles roll towards the feed inlet 9 with the vibration, and are then transported again by the transmission component 2 to the feed inlet 3 for secondary pelletizing. This prevents unqualified rubber particles from accumulating and blocking the screen holes, allowing qualified rubber particles to pass through the screen holes quickly and improving pelletizing efficiency.

[0024] like Figure 3 and Figure 5As shown, the linkage assembly 7 includes a drive wheel 701 fixedly mounted on the transmission assembly 2 and a driven wheel 702 rotatably mounted on the side of the pelletizing box 1. A transmission belt 703 is wound around the circumference of the drive wheel 701 and the driven wheel 702. A lifting column 704 is provided on the driven wheel 702. The driven wheel 702 is rotatably positioned below the feed outlet 9. A notch is provided on the side of the pelletizing box 1 for the lifting column 704 to pass through. The transmission assembly 2 includes a transmission cylinder 201 fixedly mounted on one side of the pelletizing box 1. The feed inlet at the bottom of the transmission cylinder 201 is connected to the feed outlet 9, and the discharge outlet at the top is located above the feed inlet 3. A spiral blade 202 is rotatably mounted inside the transmission cylinder 201. A transmission motor 204 is fixedly mounted on the support frame 8. The output shaft of the transmission motor 204 is fixedly connected to the bottom end of the spiral blade 202. A fixing member 203 is provided in the middle of the outer side of the transmission cylinder 201, and one end of the fixing member 203 is fixedly mounted on the pelletizing box 1.

[0025] When in use, the staff starts the transmission motor 204 through the main control panel. The transmission motor 204 drives the spiral blade 202 to rotate. The spiral blade 202 conveys the unqualified rubber particles that enter the bottom through the feed port to the top. The unqualified rubber particles fall from the top discharge port into the feed port 3 for secondary pelleting.

[0026] During the rotation of the transmission motor 204, the drive wheel 701 is driven to rotate. The drive wheel 701 drives the driven wheel 702 to rotate through the transmission belt 703. During the rotation of the driven wheel 702, the lifting column 704 on its top surface repeatedly passes under the screening plate 5 to lift the screening plate 5, thereby causing the screening plate 5 to rise and fall at high frequency in the vertical direction, forming a vibration mode.

[0027] By setting up the drive wheel 701, the driven wheel 702, and the lifting column 704, when the transmission component 2 is running, it drives the drive wheel 701 to rotate, which in turn drives the driven wheel 702 to rotate. This causes the lifting column 704 to repeatedly lift the screening plate 5, causing the screening plate 5 to vibrate. This rapidly screens the rubber particles, accelerating the fall of qualified rubber particles while sending unqualified rubber particles to the transmission component 2 for secondary pelletizing. This prevents unqualified rubber particles from accumulating on the screening plate 5 and clogging the screen holes, and promotes the rapid fall of qualified rubber particles for subsequent production steps, thereby improving pelletizing efficiency.

[0028] like Figure 4 As shown, the vibration assembly 6 includes a fixed plate 601 fixedly installed on the inner side of the pelletizing box 1. A limiting post 603 is fixedly installed on the top surface of the fixed plate 601, and the screening plate 5 is slidably sleeved on the limiting post 603. A vibration spring 602 is sleeved on the outside of the limiting post 603. The top end of the vibration spring 602 is fixedly connected to the bottom surface of the screening plate 5, and the bottom end is fixedly connected to the top surface of the fixed plate 601.

[0029] In use, the lifting column 704 lifts the screening plate 5 so that it slides and rises along the limiting column 603. As the screening plate 5 rises, the vibration spring 602 is stretched. When the lifting column 704 leaves the screening plate 5, the vibration spring 602 drives the screening plate 5 to fall and reset. This process is repeated so that the screening plate 5 enters the vibration screening mode to screen the rubber particles.

[0030] The working principle of this utility model: First, the machine is started for trial operation. The staff starts the pelletizing motor 401 and the transmission motor 204 through the main control panel. The pelletizing motor 401 drives the pelletizing roller 402 to start rotating, and the transmission motor 204 drives the spiral blade 202 to rotate.

[0031] Secondly, the drive screen plate 5 enters the vibration mode. During the rotation of the transmission motor 204, the drive wheel 701 rotates. The drive wheel 701 drives the driven wheel 702 to rotate through the transmission belt 703. During the rotation of the driven wheel 702, the lifting column 704 on its top surface repeatedly passes under the screen plate 5. The lifting column 704 lifts the screen plate 5, causing it to slide and rise along the limit column 603. As the screen plate 5 rises, the vibration spring 602 is stretched. When the lifting column 704 leaves the screen plate 5, the vibration spring 602 drives the screen plate 5 to fall and reset. This process is repeated, causing the screen plate 5 to enter the vibration screening mode. This causes the screen plate 5 to rise and fall at high frequency in the vertical direction, forming a vibration mode for subsequent screening of rubber particles.

[0032] Then, rubber raw materials are fed into the pelletizing box 1 through the feed inlet 3. The rubber raw materials pass between the pelletizing rollers 402 and are cut into rubber pellets by the pelletizing rollers 402. The rubber pellets fall onto the screen plate 5.

[0033] Finally, the unqualified particles are transported for secondary pelletizing. The qualified rubber particles fall from the sieve holes of the sieve plate 5 into the bottom of the pelletizing box 1, while the unqualified rubber particles roll towards the feed inlet 9 with vibration. The unqualified rubber particles enter the feed inlet of the conveying cylinder 201 through the feed inlet 9. The spiral blades 202 convey the unqualified rubber particles that have entered the bottom of the feed inlet to the top. The unqualified rubber particles fall from the top discharge outlet into the feed inlet 3 for secondary pelletizing.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
