Description

Technical Field

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

[0002] With the continuous increase in the number of automobiles, the quantity of waste tires is becoming increasingly large. China is the world's largest rubber consumer, but the natural rubber resources are scarce. Waste tires contain a large amount of rubber components, which can be made into recycled rubber for manufacturing various rubber products, alleviating the rubber shortage situation and reducing the dependence on imported rubber resources. Through innovative processes, waste tires can be efficiently converted into high-quality rubber powder. This process first involves crushing the tires through professional crushing equipment.

[0003] For the existing tire crushing device, the hopper diameter is larger than the tire diameter. After the tire falls into the hopper, it may be in a horizontal state, resulting in its inability to be immediately drawn into the gap between the crushing rollers, prolonging the time required to crush a single tire. When dealing with a large number of tires, a lot of time will be wasted, leading to low tire crushing efficiency. Summary of the Invention

[0004] In order to overcome the drawback that the existing tire crushing device may cause the tire to be in a horizontal state after falling into the hopper, resulting in its inability to be immediately drawn into the gap between the crushing rollers and thus low tire crushing efficiency, the technical problem to be solved is: to provide a waste tire crushing device in which the crushing rollers can more quickly clamp the tire, prevent the tire from being in a horizontal state on the surface of the crushing rollers, and thereby improve the tire crushing efficiency.

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

[0006] Furthermore, it also includes a guide post. A guide post is provided on the crushing frame, a tire is placed on the guide post, a driving motor II is provided on the installation frame, and a cutting blade is provided on the output shaft of the driving motor II.

[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 I 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 baffle rods are rotatably connected to the mounting frame, a column gear 1 is provided on the two baffle rods, a torsion spring 2 is connected between the two column gears 1 and the mounting frame, two gear rods 1 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 column 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 sliding groove of the guide frame are slidably connected.

[0010] Furthermore, the swing mechanism includes a swing rod, which is rotatably connected to the crushing frame, and a column gear 2 is provided 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 slidably 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 the support column.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The tire will contact 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 direction close to 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 place 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] 2. After the push block contacts the tire, the pressure block will move above the tire. Then, the sliding mounting block will continue 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 the pressure block will move toward 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 it. 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] 3. When the swing arm swings to push the broken end of the tire toward the crushing roller, the tire will contact the support column, and the support column will restrict the tire so that the deformation range of the tire is limited to the range from the tire break to the contact with the support column, so that the tire break can be better pushed toward the crushing roller, so that the tire can be better twisted by the crushing roller, and the tire crushing efficiency is further improved.

The driving mechanism is used to provide power, the pushing mechanism is used to drive the crushed material, and the swinging mechanism is used to assist in crushing.

[0032] It further includes a guide post 7. The guide post 7 is connected to the crushing frame 3 by bolts. A tire 8 is placed on the guide post 7. A second driving motor 81 is provided on the installation frame 2. A cutting blade 82 is provided on the output shaft of the second driving motor 81. The cutting blade 82 is used to cut the tire 8.

[0033] The driving mechanism includes an electric slide rail 91. The electric slide rail 91 is connected to the installation frame 2 by bolts. A slider 92 is slidably connected to the electric slide rail 91. A guide frame 93 is connected to the installation frame 2 by bolts. A baffle 94 is rotatably connected to the guide frame 93. Two first torsion springs 95 are connected between the baffle 94 and the guide frame 93.

[0034] The driving mechanism includes a sliding mounting block 101. The sliding mounting block 101 is slidably connected to the slider 92. A pushing block 102 is bolted to the sliding mounting block 101. Two retaining rods 103 are rotatably connected to the mounting frame 2. The retaining rods 103 are used to block the tire 8. A first column gear 104 is provided on each of the two retaining rods 103. A second torsion spring 105 is connected between each of the two first column gears 104 and the mounting frame 2. Two first rack bars 106 are slidably connected to the mounting frame 2. A top frame 107 is provided on the sliding mounting block 101. A tension spring 1011 is connected between the sliding mounting block 101 and the slider 92. A roller 1012 is rotatably connected to the sliding mounting block 101.

[0035] A chute is formed in the guiding frame 93. The sliding mounting block 101 is slidably connected to the chute of the guiding frame 93. The guiding frame 93 guides the sliding mounting block 101 during the sliding process of the sliding mounting block 101.

[0036] The swinging mechanism includes a swinging rod 111. The swinging rod 111 is rotatably connected to the crushing frame 3. The swinging rod 111 is used to push the tire 8 towards the crushing roller 4. A second column gear 112 is provided on the swinging rod 111. A second rack bar 113 is slidably connected to the mounting frame 2. The second rack bar 113 meshes with the second column gear 112. A reset spring 114 is connected between the second rack bar 113 and the mounting frame 2. A top rod 115 is bolted to the sliding mounting block 101.

[0037] At first, the user places the tire 8 to be broken on the guide post 7. The tire 8 slides along the guide post 7 in the direction towards the crushing frame 3. The tire 8 sliding on the guide post 7 will be blocked by the stop bar 103. Subsequently, the user activates the electric slide rail 91, and the slider 92 will move along the electric slide rail 91 in the direction towards 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 blocked by the baffle 94, causing the sliding mounting block 101 to be squeezed and move along the chute of the guide frame 93 in the direction away from the slider 92. The tension spring 1011 is stretched. The movement of the sliding mounting block 101 drives the push block 102 and the top frame 107 to move together. After the squeezing force of the guide frame 93 on the sliding mounting block 101 no longer increases, the top frame 107 will contact the two first rack bars 106. Subsequently, the sliding mounting block 101 continues to move, and the top frame 107 will gradually squeeze the first rack bar 106. The first rack bar 106 will engage with the first column gear 104, and the second torsion spring 105 is twisted. The rotation of the first column gear 104 drives the stop bar 103 to rotate, and the rotation of the stop bar 103 will disengage from the tire 8. Subsequently, the push block 102 will contact the tire 8, and the movement of the push block 102 drives the tire 8 to move together in the direction towards the crushing frame 3. The user activates the second drive motor 81, and the output shaft of the second drive motor 81 drives the cutting blade 82 to rotate. During the movement of the tire 8, it will contact the cutting blade 82, and the cutting blade 82 will cut the tire 8. Subsequently, the slider 92 continues to move, and the top frame 107 will disengage from the first rack bar 106. The reset of the second torsion spring 105 drives the first column gear 104 and the stop bar to reset. The reset of the first column gear 104 drives the first rack bar 106 to reset. The cut tire 8 will be pushed open and pushed into the crushing frame 3. After the tire 8 moves into the crushing frame 3, the swing rod 111 will pass through the tire 8. Subsequently, the top rod 115 fixed on the sliding mounting block 101 will squeeze the second rack bar 113, and the second rack bar 113 will move in the direction towards the second column gear 112 under the squeeze. The return spring 114 is compressed. The second rack bar 113 engages with the second column gear 112, and the rotation of the second column gear 112 drives the swing rod 111 to rotate. The rotation of the swing rod 111 will push the broken end of the tire 8 in the direction towards the crushing roller 4. The user turns on the first drive motor 6, and the rotation of the output shaft of the first drive motor 6 drives one of the transmission gears 5 to rotate. The rotation of one of the transmission gears 5 drives the other transmission gear 5 to rotate. The rotation of the two transmission gears 5 respectively drives the two crushing rollers 4 to rotate. The rotation of the two crushing rollers 4 will wind up one end of the tire 8 pushed down by the swing rod 111. After the tire 8 is wound up by the two crushing rollers 4, it will be broken. During the process of the tire 8 being wound up by the two crushing rollers 4, the tire 8 in the area below the sliding mounting block 101 will deform and contact the roller column 1012 on the sliding mounting block 101. During the movement of the tire 8, it will rub against the roller column 1012, and the roller column 1012 will rotate, thereby reducing the wear between it and the tire 8. Under the twisting force of the two crushing rollers 4, the tire 8 will gradually disengage from the guide post 7.Thus, a primary crushing process of the tire 8 is completed. After the shift lever is reset, the user can continue to place the tire 8 on the guide post 7. After the primary crushing of the tire 8 is completed, the slider 92 will continue to move a certain distance, so that the sliding mounting block 101 is no longer squeezed by the guide frame 93. The tension spring 1011 resets to drive the sliding mounting block 101 to reset. The sliding mounting block 101 returns to the initial height, and the ejector rod 115 and the second rack 113 are disengaged. The return spring 114 resets to drive the second rack 113 to reset. The second rack 113 resets to drive the second column gear 112 to reset. The second column gear 112 resets to drive the swing rod 111 to reset. Subsequently, the slider 92 moves in the reverse direction to reset. The reset of the slider 92 drives the sliding mounting block 101 to reset. During the reset process of the sliding mounting block 101, it will squeeze the baffle 94. The baffle 94 will swing when being squeezed, and the first torsion spring 95 is twisted. Subsequently, the sliding mounting block 101 and the baffle 94 are disengaged. The torsion spring resets to drive the baffle 94 to reset. The sliding mounting block 101 will move from above the next tire 8 to the initial position. In this way, the crushing process of the tire 8 is realized by repeating the above steps. By cutting the tire 8 and sending the cut surface of the tire 8 to the stranding part of the crushing roller 4, it is beneficial for the crushing roller 4 to more quickly strand the tire 8, prevent the tire 8 from being horizontal on the surface of the crushing roller 4, and thus improve the crushing efficiency of the tire 8.

[0038] Embodiment 2: On the basis of Embodiment 1, as Figures 11 - 13 shown, it further includes a fixing mechanism for fixing the tire 8. The fixing mechanism includes a pressing rod 121. Two pressing rods 121 are slidably connected to the sliding mounting block 101. Two pressing blocks 122 are provided on each of the two pressing rods 121. The pressing blocks 122 are used to fix the tire 8. Two pressure springs 123 are connected between each of the two pressing rods 121 and the sliding mounting block 101. Two pressing frames 124 are provided on the mounting block.

[0039] It further includes a supporting post 13. The supporting post 13 is bolted to the crushing frame 3. The supporting post 13 is used to support the tire 8.

[0040] When the sliding mounting block 101 moves in the direction away from the sliding block 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 will be hit and the pressure block 122 will 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 be disengaged 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, so that the tire 8 can be better twisted by the crushing roller 4, and the crushing efficiency of the tire 8 is further improved.

It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
