Description

Technical Field

[0001] This invention relates to the field of rubber recycling technology, and more specifically, to a recycling and processing device for rubber products. Background Technology

[0002] Rubber products are a general term for products made from natural and synthetic rubber through a series of processing techniques. Their core characteristics include high elasticity, wear resistance, shock absorption, insulation, and sealing. They are widely used in daily life, industrial production, transportation, national defense, and medical and health fields. The recycling of rubber products is a crucial link in environmental protection and resource recycling, involving the crushing of rubber products into rubber raw materials for reuse. The recycling process begins with conveying the whole rubber product to a crusher via a conveyor belt. The crusher breaks the rubber product down into rubber fragments, which are then conveyed to a washing tank. The washing tank's internal agitator cleans the rubber fragments, removing impurities and preventing them from affecting the purity of the subsequently processed rubber raw materials.

[0003] Currently, when cleaning rubber fragments, because rubber has a lower density than water, it will float on the water surface. Therefore, the agitation mechanism cannot guarantee the cleaning effect of the rubber fragments. Furthermore, the rubber fragments need to be manually removed after cleaning, which reduces the overall efficiency of the cleaning operation. Summary of the Invention

[0011] Furthermore, the pressing mesh frame has a through hole for the lifting rope to pass through, and the lifting sleeve is located below the through hole and can abut against the pressing mesh frame to drive the pressing mesh frame to move upward.

[0012] Furthermore, each of the two sliding seats is provided with a horizontal limiting strip on the side that is close to each other, and the mesh plate is in a horizontal state when it rotates to abut against the horizontal limiting strip; both ends of the sliding seat are provided with limiting blocks, and both ends of the cleaning tank are provided with limiting grooves for the limiting blocks to slide.

[0013] Furthermore, the pull-down mechanism includes a dual-axis motor, with pull-down discs mounted on both output shafts of the dual-axis motor. A pull-down rope is wound around the pull-down disc, and a through hole is provided on the bottom frame. The bottom end of the pull-down rope passes through the through hole and is fixedly connected to the bottom surface of the pressing mesh frame.

[0014] Furthermore, the pushing mechanism includes a pushing plate and a pushing electric cylinder. The bottom of the pushing plate has water grooves distributed along its own length direction. The cylinder of the pushing electric cylinder is fixedly installed outside the cleaning tank.

[0020] 1. This invention features a bottom frame and a stirring mechanism at the bottom of the cleaning tank. By pressing the mesh frame, rubber fragments suspended on the water surface are pressed into the bottom frame to achieve better cleaning results. Support members are provided on both sides to guide the rubber fragments during the pressing process. After cleaning, the support members rotate to a horizontal position and are located at the bottom of the rubber fragments. By driving the support members upward, the rubber fragments can be supported and moved upward until they leave the water surface. Then, a pushing mechanism pushes the rubber fragments out of the cleaning tank.

[0021] 2. The present invention first rotates the mesh plate to a horizontal state by setting an upward lifting mechanism, and then drives the mesh plate and the sliding seat to move upward simultaneously, so as to switch the state of the support component so as to carry the rubber fragments upward after cleaning; by setting a downward pulling mechanism to pull the pressing mesh frame, the pressing mesh frame can overcome the buoyancy of the rubber fragments and press the rubber fragments downward into the bottom frame.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] Example

[0034] The following is for reference Figures 1-8 As shown in the illustration, and further explained with reference to specific embodiments, this embodiment provides a recycling and processing device for rubber products. Figure 1As shown, the system includes a conveyor belt 1, a crusher 2, a screw conveyor 3, and a cleaning tank 4. The conveyor belt 1 is inclined and its highest end faces the inlet end of the crusher 2. The inlet end of the screw conveyor 3 is located at the bottom of the outlet end of the crusher 2, and the outlet end of the screw conveyor 3 faces the cleaning tank 4. The conveyor belt 1 transports the whole piece of rubber to the inlet end of the crusher 2. After being crushed, the rubber product becomes rubber fragments and enters the screw conveyor 3 from the outlet end at the bottom of the crusher 2. The screw conveyor 3 transports the rubber fragments to the cleaning tank 4 for cleaning.

[0035] Reference Figure 2 As shown, the cleaning tank 4 has a feeding notch 41 for rubber fragments to enter. A pushing mechanism 5 is provided at the lower part of the feeding notch 41. A bottom frame 44 is provided at the bottom of the cleaning tank 4. The top of the bottom frame 44 is flared and fixed to the inner wall of the cleaning tank 4 by welding. The bottom opening of the bottom frame 44 is designed to allow impurities attached to the rubber fragments to sink to the bottom of the cleaning tank 4. A stirring mechanism 45 for stirring the rubber fragments is provided inside the bottom frame 44. The stirring mechanism 45 causes the rubber fragments to rub and squeeze against each other, thereby improving the cleaning effect.

[0036] Reference Figure 2 , Figure 3 As shown, a pressing mesh frame 6 is provided above the bottom frame 44 for pressing rubber fragments into the bottom frame 44. Flexible bonding plates 61 are provided on both sides of the pressing mesh frame 6. Support members 7 are provided on both sides of the top of the bottom frame 44. Each support member 7 includes a sliding seat 71 and a mesh plate 72. The sliding seat 71 is slidably disposed within the cleaning tank 4 along its height direction, and the top of the mesh plate 72 is rotatably disposed on the sliding seat 71. When the two mesh plates 72 are in a nearly vertical state, their bottom ends abut against the bottom frame 44, allowing the rubber fragments to be guided into the bottom frame 44. When the two mesh plates 72 are in a horizontal state, they are located at the bottom of the rubber fragments and can support them. When the rubber fragments are transported to the cleaning tank 4, because the density of the rubber fragments is less than that of water, they will float on the water surface. Therefore, the pressing mesh frame 6 is needed to press the rubber fragments into the bottom frame 44 so that they can be cleaned within the bottom frame 44 by the stirring mechanism 45. During the process of pressing the rubber fragments into the bottom frame 44, the mesh plate 72 is kept in a relatively vertical state. After the rubber fragments are cleaned by the stirring mechanism 45 inside the bottom frame 44, the pressing mesh frame 6 is moved upward so that the rubber fragments can move to the water surface under the action of buoyancy. Then the mesh plate 72 is rotated to a horizontal state. At this time, the two mesh plates 72 are located at the bottom of the rubber fragments. By moving the mesh plates 72 upward, the rubber fragments can be supported and moved upward to leave the water surface. Then the pushing mechanism 5 pushes the rubber fragments to make them move out of the cleaning tank 4.

[0037] Reference Figure 3 , Figure 4As shown, lifting mechanisms 8 are provided on both sides of the top of the cleaning tank 4. The lifting mechanisms 8 can drive the two mesh plates 72 to rotate towards each other to a horizontal state and move upward. Specifically, the lifting mechanism 8 includes a support base 81, a lifting motor 82, a lifting plate 83, a lifting rope 84, and a connecting rope 85. The support base 81 is fixedly installed on the top of the cleaning tank 4. Two support blocks 811 are provided on the support base 81. The lifting plate 83 is rotatably installed between the two support blocks 811. The lifting motor 82 is installed on one of the support blocks 811, and the output shaft of the lifting motor 82 is fixedly connected to the lifting plate 83. The lifting rope 84 is wound around the lifting plate 83. The two ends of the connecting rope 85 are respectively fixedly connected to the bottom ends of the two mesh plates 72. The bottom end of the lifting rope 84 is provided with a lifting sleeve 841, which is sleeved on the middle of the connecting rope 85. The lifting motor 82 is started, which drives the lifting plate 83 to rotate, thereby winding up the lifting rope 84. The bottom end of the lifting rope 84 can apply tension to the middle section of the connecting rope 85 through the lifting sleeve 841, so that the connecting rope 85 is folded in half from the middle and drives the net plates 72 on both sides to rotate towards each other and reach a horizontal state. When the lifting rope 84 continues to pull the connecting rope 85 through the lifting sleeve 841, it can drive the two net plates 72 to move upward at the same time, thereby supporting the rubber fragments at the bottom and driving the rubber fragments to move upward until they are removed from the water surface.

[0038] Reference Figure 4 As shown, each of the two sliding seats 71 has a horizontal limiting strip 711 on one side that is close to each other. When the mesh plate 72 rotates to abut against the horizontal limiting strip 711, it is in a horizontal state and cannot continue to rotate upward. Therefore, when the connecting rope 85 is pulled upward after rotating to a horizontal state, the two mesh plates 72 will move upward as a whole. Each end of the sliding seat 71 has a limiting block 712. Each end wall of the cleaning box 4 has a limiting groove for the limiting block 712 to slide. Through the cooperation of the limiting block 712 and the limiting groove, the sliding seat 71 is guided to ensure the movement trajectory of the sliding seat 71 and to prevent the support 7 from shifting in position within the cleaning box 4.

[0039] Reference Figure 3 , Figure 4As shown, the outer wall of the cleaning tank 4 is equipped with a pull-down mechanism 9 for driving the pressing mesh frame 6 downward. The pull-down mechanism 9 includes a dual-axis motor 91, and each of the two output shafts of the dual-axis motor 91 is equipped with a pull-down plate 92. A pull-down rope 93 is wound around the pull-down plate 92. A through hole is opened on the bottom frame 44, and the bottom end of the pull-down rope 93 passes through the through hole and is fixedly connected to the bottom surface of the pressing mesh frame 6. When the dual-axis motor 91 is started, the output shaft of the dual-axis motor 91 drives the two pull-down plates 92 to rotate simultaneously and wind the pull-down rope 93. This allows the pull-down rope 93 to apply a downward pulling force to the pressing mesh frame 6, thereby enabling the pressing mesh frame 6 to press down the rubber fragments floating on the water surface, ensuring that the rubber fragments can enter the bottom frame 44 and achieve a better cleaning effect under the action of the stirring mechanism 45.

[0040] Reference Figure 4 , Figure 5 As shown, the clamping mesh frame 6 has a through hole for the lifting rope 84 to pass through. The lifting sleeve 841 is located below the through hole and can abut against the clamping mesh frame 6 to drive the clamping mesh frame 6 to move upward. When the lifting rope 84 pulls the connecting rope 85, the connecting rope 85 will first fold in half. During this process, the lifting sleeve 841 abuts against the clamping mesh frame 6 and drives the clamping mesh frame 6 to move upward, so that the clamping mesh frame 6 and the mesh plate 72, which is in a horizontal state after rotation, are always kept at a distance to avoid the clamping mesh frame 6 obstructing the movement of the pushing mechanism 5 when the rubber fragments on the mesh plate 72 are pushed out later. It should be noted that when the mesh plate 72 is lifted by the lifting mechanism 8, the dual-axis motor 91 of the pulling mechanism 9 is started and the output shaft of the dual-axis motor 91 is rotated in reverse so that the pulling plate 92 unwinds the pulling rope 93, so that the clamping mesh frame 6 has space to move upward and can move upward under the drive of the lifting mechanism 8.

[0041] Reference Figure 2 As shown, the washing tank 4 has a discharge port and a baffle 42 for blocking the discharge port on the side away from the pushing mechanism 5. A scum outlet 43 is provided directly below the discharge port. During the washing of rubber fragments, the pressing mesh frame 6 presses the rubber fragments into the bottom frame 44 and washes them through the stirring mechanism 45. During the washing process, the sedimented impurities fall into the bottom wall of the washing tank 4 from the opening at the bottom of the bottom frame 44, while the suspended impurities can float to the water surface through the pressing mesh frame 6. The pushing mechanism 5 pushes the suspended impurities out of the scum outlet 43. After the washing process is completed, the mesh plate 72 moves upward to move the rubber fragments upward until they leave the water surface. Then, the baffle 42 is opened and the pushing mechanism 5 removes the rubber fragments from the discharge port.

[0042] Reference Figure 2 , Figure 6As shown, the pushing mechanism 5 includes a pushing plate 51 and a pushing cylinder 52. The bottom of the pushing plate 51 has water grooves distributed along its length to improve the smoothness of the pushing plate 51 when moving in water. The cylinder of the pushing cylinder 52 is fixedly installed on the outside of the cleaning tank 4. The piston rod of the pushing cylinder 52 extends into the cleaning tank 4 and can drive the pushing plate 51 to move along the width of the cleaning tank 4. A vertical seat 53 is provided on the piston rod of the pushing cylinder 52. A guide groove 531 is opened on the vertical seat 53 along its length. A guide slider 511 is provided on the pushing plate 51 and the guide slider 511 is slidably connected in the guide groove 531. When the lifting mechanism 8 drives the support member 7 to move upward, the support member 7 can abut against the pushing plate 51 and drive the pushing plate 51 to move synchronously. In the initial state, the pusher plate 51 moves downward under the action of gravity and causes the guide slider 511 to slide to the bottom of the guide groove 531. At this time, when the pusher plate 51 is moved by the pusher cylinder 52, the pusher plate 51 can push the impurities suspended on the water surface, so that the suspended impurities are removed from the scum outlet 43 and out of the cleaning box 4. When the screen plate 72 moves upward under the action of the lifting mechanism 8, when the screen plate 72 comes into contact with the pusher plate 51, it can drive the pusher plate 51 to move upward a certain distance. At this time, when the pusher plate 51 is moved by the pusher cylinder 52, the pusher plate 51 can push the cleaned rubber fragments on the screen plate 72, so as to remove the rubber fragments from the outlet and out of the cleaning box 4.

[0043] Reference Figure 2 , Figure 7 As shown, the screw conveyor 3 has an elastic guide trough 31 at its outlet end. One side of the cleaning tank 4 has a lever 46 for moving the elastic guide trough 31 to the feed opening 41; the other side of the cleaning tank 4 has a traction member 47 for opening the discharge port by driving the baffle 42. The lever 46 moves the elastic guide trough 31 to guide the rubber fragments into the cleaning tank 4. After the rubber fragments are conveyed to the cleaning tank 4, the lever 46 is moved back to its initial position, and the elastic guide trough 31 returns to its initial position under its own elastic force and moves out of the cleaning tank 4 to avoid obstructing the movement of the clamping mesh frame 6. After cleaning the rubber fragments, the traction member 47 opens the baffle 42 to open the discharge port, allowing the rubber fragments to be discharged through the discharge port.

[0044] Reference Figure 7As shown, specifically, the actuating member 46 includes first sliding rods 461 slidably disposed at both ends of the cleaning tank 4, and an actuating rod 462 is provided between the two first sliding rods 461. An insertion part 4621 capable of being inserted into the feeding notch 41 is provided in the middle of the actuating rod 462. By moving the actuating member 46 toward the cleaning tank 4 and pressing the elastic guide groove 31 to the feeding notch 41 by the insertion part 4621, rubber fragments can be easily introduced into the cleaning tank 4. The traction member 47 includes second sliding rods 471 slidably disposed at both ends of the cleaning tank 4, and a traction rod 472 is provided between the two second sliding rods 471. A traction belt 473 is provided on the traction rod 472. The top end of the baffle 42 is hinged to the cleaning tank 4, and the traction belt 473 is connected to the bottom end of the baffle 42. By moving the traction member 47 away from the cleaning box 4, the baffle 42 can be pulled by the traction belt 473 to open the discharge port, thereby facilitating the pushing mechanism 5 to push the cleaned rubber fragments out of the cleaning box 4.

[0045] The cleaning tank 4 is provided with a drive assembly 48 for driving the actuating member 46 and the traction member 47 to move closer to or further away from each other. The drive assembly 48 includes a drive base 481, a drive motor 482, a gear 483, an upper rack 484, and a lower rack 485. The drive base 481 is fixedly mounted on the cleaning tank 4, the drive motor 482 is fixedly mounted on the drive base 481, the gear 483 is rotatably mounted on the output shaft of the drive motor 482, the upper rack 484 is fixedly mounted on the first slide rod 461, and the lower rack 485 is fixedly mounted on the second slide rod 471. The upper rack 484 and the lower rack 485 are located on both sides of the gear 483 and are both meshed with the gear 483. When the drive motor 482 is started, it drives the gear 483 to rotate. When the gear 483 rotates, it drives the upper rack 484 and the lower rack 485 to move in opposite directions synchronously. This causes the actuating member 46 to move the elastic guide groove 31 into the feed notch 41, while the traction member 47 does not pull the baffle 42, thus preventing the rubber fragments from falling out of the discharge port after being introduced from the feed notch 41. When the actuating member 46 moves out of the feed notch 41, the elastic guide groove 31 moves out of the feed notch 41 under its own elastic force. At the same time, the traction member 47 pulls the baffle 42 to open the discharge port, so as to facilitate the discharge of the rubber fragments.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
