Description

Technical Field

[0001] The invention relates to the technical field of waste tire recycling, in particular to a waste tire crushing device. Background Art

[0002] With the continuous increase in car ownership, the amount of scrap tires is growing. my country is the world's largest rubber consumer, but natural rubber resources are scarce. Scrap tires contain a large amount of rubber components, which can be made into recycled rubber for the manufacture of various rubber products, alleviating the rubber shortage and reducing dependence on imported rubber resources. Through innovative processing, scrap tires can be efficiently converted into high-quality rubber powder. This process begins with the tires being crushed using specialized crushing equipment.

[0003] However, the hopper diameter of the existing tire crushing device is larger than the tire diameter. After the tire falls into the hopper, it may be in a horizontal state, which prevents it from being immediately rolled between the crushing rollers. This prolongs the time it takes to crush a tire, wastes a lot of time when processing large quantities of tires, and results in low tire crushing efficiency. Summary of the Invention

[0004] In order to overcome the disadvantage of the existing tire crushing device that the tire may be in a horizontal state after falling into the hopper, which makes it impossible to be immediately rolled between the crushing rollers, resulting in low tire crushing efficiency, the technical problem to be solved is to provide a waste tire crushing device with a crushing roller that can twist the tire more quickly, prevent the tire from being horizontal on the surface of the crushing roller, and thus improve the tire crushing efficiency.

[0005] The technical solution is as follows: A waste tire crushing device includes a base, a mounting frame is provided on the base, a crushing frame is provided on the mounting frame, two crushing rollers are rotatably connected to the crushing frame, both crushing rollers are provided with transmission gears, a drive motor is provided on the crushing frame, an output shaft of the drive motor is connected to one of the transmission gears, and a driving mechanism, a pushing mechanism and a swinging mechanism are provided on the mounting frame.

[0006] Furthermore, it also includes a guide column, the crushing frame is provided with a guide column, a tire is placed on the guide column, the mounting frame is provided with a second drive motor, and a cutting blade is provided on the output shaft of the second drive motor.

[0007] Furthermore, the driving mechanism includes an electric slide rail, an electric slide rail is provided on the installation frame, a slider is slidably connected to the electric slide rail, a guide frame is provided on the installation frame, a baffle is rotatably connected to the guide frame, and two torsion springs are connected between the baffle and the guide frame.

[0008] Furthermore, the pushing mechanism includes a sliding mounting block, a sliding mounting block is slidably connected to the slider, a push block is provided on the sliding mounting block, two baffles are rotatably connected to the mounting frame, each baffle is provided with a column gear 1, a torsion spring 2 is connected between the two column gears 1 and the mounting frame, two gear rods are slidably connected to the mounting frame, a top frame is provided on the sliding mounting block, a tension spring is connected between the sliding mounting block and the slider, and a roller is rotatably connected to the sliding mounting block.

[0009] Furthermore, a sliding groove is provided on the guide frame, and the sliding mounting block and the guide frame sliding groove are slidably connected.

[0010] Furthermore, the swing mechanism includes a swing rod, which is rotatably connected to the crushing frame, and is provided with a column gear 2 on the swing rod. A gear rod 2 is slidably connected to the mounting frame, and the gear rod 2 is meshed with the column gear 2. A reset spring is connected between the gear rod 2 and the mounting frame, and a top rod is provided on the sliding mounting block.

[0011] Furthermore, it also includes a fixing mechanism, which includes a pressure rod, two pressure rods are slidingly connected to the sliding mounting block, two pressure blocks are provided on the two pressure rods, two pressure springs are connected between the two pressure rods and the sliding mounting block, and two pressure frames are provided on the mounting block.

[0012] Furthermore, it also includes a support column, and the crushing frame is provided with a support column.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The tire will come into contact with the cutting blade during movement, and the cutting blade will cut the tire. The rotation of the swing arm will push the broken end of the tire toward the crushing roller. The rotation of the two crushing rollers will reel up the end of the tire pushed down by the swing arm. The tire will be crushed after being reeled up by the two crushing rollers. By cutting the tire and sending the cut surface of the tire to the twisting position of the crushing rollers, it is beneficial for the crushing rollers to twist the tire more quickly, preventing the tire from being horizontal on the surface of the crushing rollers, thereby improving the tire crushing efficiency.

[0014] After the push block contacts the tire, the pressure block will move above the tire. Then, the sliding mounting block continues to move, the pressure rod will contact the pressure frame, and the pressure frame will gradually hit the pressure rod. The pressure rod will be hit and will drive the pressure block to move closer to the tire. The pressure spring will be compressed. After the pressure frame squeezes the pressure rod and no longer increases, the pressure block will contact the tire and fix the tire. Then the tire will contact the cutting blade. In this way, the tire can be more stable when being cut by the cutting blade, thereby improving the cutting quality.

[0015] When the swing arm swings to push the broken end of the tire toward the crushing roller, the tire will contact the anti-pillar, and the anti-pillar will restrict the tire so that the deformation range of the tire is limited to the range from the broken end of the tire to the contact with the anti-pillar, so that the broken end of the tire can be better pushed toward the crushing roller, thereby further allowing the tire to be better twisted by the crushing roller, further improving the tire crushing efficiency.

[0037] At first, the user places the tire 8 to be crushed on the guide column 7, and the tire 8 slides along the guide column 7 in the direction close to the crushing frame 3. The tire 8 sliding on the guide column 7 will be held by the blocking rod 103. Then, the user starts the electric slide rail 91, and the slider 92 will move along the electric slide rail 91 in the direction close to the crushing frame 3. The movement of the slider 92 drives the sliding mounting block 101 to move together. During the movement of the sliding mounting block 101, it will be held by the baffle 94, so that the sliding mounting block 101 will move along the guide frame 93 slide groove in the direction away from the slider 92. The tension spring 1011 is stretched, and the movement of the sliding mounting block 101 will drive the push block 102 and the top frame 107 to move together. When the squeezing force of the guide frame 93 on the sliding mounting block 101 no longer increases After the addition, the top frame 107 will contact the two gear rods 106, and then the sliding mounting block 101 continues to move, the top frame 107 will gradually squeeze the gear rod 106, the gear rod 106 will mesh with the column gear 104, the torsion spring 2 105 will be twisted, the column gear 104 will rotate to drive the baffle 103 to rotate, the baffle 103 will rotate and disengage from the tire 8, and then the push block 102 will contact the tire 8, and the movement of the push block 102 will drive the tire 8 to move toward the crushing frame 3, the user starts the drive motor 2 81, the output shaft of the drive motor 2 81 will drive the cutting blade 82 to rotate, the tire 8 will contact the cutting blade 82 during the movement, and the cutting blade 82 will cut the tire 8, and then the slider 92 continues to move, the top frame 107 will contact the gear rod 106, the gear rod 106 will mesh with the column gear 104, the torsion spring 2 105 will be twisted, the column gear 104 will rotate to drive the baffle 103, and the baffle 103 will rotate and disengage from the tire 8, and then the push block 102 will contact the tire 8, and the movement of the push block 102 will drive the tire 8 to move together in the direction close to the crushing frame 3, the user starts the drive motor 2 81, and the output shaft of the drive motor 2 81 will drive the cutting blade 82 to rotate, and the tire 8 will contact the cutting blade 82 during the movement, and the cutting blade 82 will cut the tire 8, and then the slider 92 continues to move, the top frame 107 will contact the gear rod The tire 8 is pushed into the crushing frame 3. After the tire 8 moves into the crushing frame 3, the swing rod 111 passes through the tire 8. Subsequently, the top rod 115 fixed on the sliding mounting block 101 squeezes the gear rod 2 113. The gear rod 2 113 is squeezed and moves toward the direction close to the column gear 2 112. The reset spring 114 is compressed, and the gear rod 2 113 is meshed with the column gear 2 112. The rotation of the column gear 2 112 drives the swing rod 111 to rotate. The rotation of the swing rod 111 pushes the broken end of the tire 8 toward the direction close to the crushing roller 4. The user turns on the drive motor 16 to drive the tire 8. The output shaft of the motor 6 rotates to drive one of the transmission gears 5 to rotate, and the rotation of one of the transmission gears 5 will drive the other transmission gear 5 to rotate. The rotation of the two transmission gears 5 will respectively drive the two crushing rollers 4 to rotate. The rotation of the two crushing rollers 4 will reel up one end of the tire 8 that is pushed down by the swing rod 111. The tire 8 will be crushed after being reeled up by the two crushing rollers 4. In the process of the tire 8 being reeled up by the crushing rollers 4, the tire 8 located in the area below the sliding mounting block 101 will be deformed and squeezed into contact with the roller 1012 on the sliding mounting block 101. During the movement of the tire 8, it will rub against the roller 1012, and the roller 1012 will rotate, thereby reducing the wear between the tire 8 and the guide column 7. Under the twisting force of the two crushing rollers 4, the tire 8 will gradually separate from the guide column 7.The tire 8 is crushed once, and after the blocking rod is reset, the user can continue to place the tire 8 on the guide column 7. After the tire 8 is crushed once, the slider 92 will continue to move a distance, so that the sliding mounting block 101 is no longer squeezed by the guide frame 93, and the tension spring 1011 resets and drives the sliding mounting block 101 to reset, and the sliding mounting block 101 returns to the initial height, the top rod 115 and the gear rod 113 are disengaged, and the reset spring 114 resets and drives the gear rod 113 to reset, and the gear rod 113 resets and drives the column gear 112 to reset, and the column gear 112 resets and drives the swing rod 111 to reset, and then the slider 92 moves in the opposite direction to reset, and the slide The reset of block 92 drives the sliding mounting block 101 to reset. During the reset process, the sliding mounting block 101 squeezes the baffle 94. The baffle 94 is squeezed and swings, and the torsion spring 1 95 is twisted. Then the sliding mounting block 101 and the baffle 94 are separated. The reset of the torsion spring drives the baffle 94 to reset. The sliding mounting block 101 moves from above the next tire 8 to the initial position. This reciprocating process is used to crush the tire 8. By cutting the tire 8 and sending the cut surface of the tire 8 to the twisting part of the crushing roller 4, the crushing roller 4 can twist the tire 8 more quickly, preventing the tire 8 from being horizontal on the surface of the crushing roller 4, thereby improving the crushing efficiency of the tire 8.

[0038] Example 2: Based on Example 1, Figure 11-13 As shown, it also includes a fixing mechanism, which is used to fix the tire 8. The fixing mechanism includes a pressure rod 121. Two pressure rods 121 are slidably connected to the sliding mounting block 101. Two pressure blocks 122 are provided on the two pressure rods 121. The pressure blocks 122 are used to fix the tire 8. Two pressure springs 123 are connected between the two pressure rods 121 and the sliding mounting block 101, and two pressure frames 124 are provided on the mounting block.

[0039] The crushing frame 3 further includes a support column 13 , which is connected to the crushing frame 3 via bolts. The support column 13 is used to support the tire 8 .

[0040] When the sliding mounting block 101 moves in the direction away from the slider 92, the sliding mounting block 101 will drive the pressure rod 121, the pressure block 122 and the pressure spring 123 to move together. After the push block 102 contacts the tire 8, the pressure block 122 will move above the tire 8. Then, the sliding mounting block 101 continues to move, the pressure rod 121 will contact the pressure frame 124, and the pressure frame 124 will gradually hit the pressure rod 121. The pressure rod 121 is hit and drives the pressure block 122 to move in the direction close to the tire 8. The pressure spring 123 is compressed. After the pressure frame 124 squeezes the pressure rod 121 and no longer increases, the pressure block 122 will contact and fix the tire 8. Then the tire 8 will contact the cutting blade 82. In this way, the tire 8 can be more stable when being cut by the cutting blade 82, thereby improving the cutting quality. After the tire 8 passes through the cutting blade 82, the pressure rod 121 will disengage from the pressure frame 124, and the pressure spring 123 will reset to drive the pressure rod 121 and the pressure block 122 to reset. In the process of the swing arm 111 swinging to push the broken end of the tire 8 toward the crushing roller 4, the tire 8 will contact the support column 13, and the support column 13 will limit the tire 8, so that the deformation range of the tire 8 is limited to the range from the broken end of the tire 8 to the contact with the support column 13, so that the broken end of the tire 8 can be better pushed toward the crushing roller 4, thereby further allowing the tire 8 to be better twisted by the crushing roller 4, further improving the crushing efficiency of the tire 8.
