Description

Technical Field

[0001] This utility model relates to the field of rubber hose processing technology, and more specifically, to an automatic rubber hose grinding production line. Background Technology

[0002] Rubber is a polymer compound with excellent resilience, insulation, and plasticity, making it widely used in everyday consumer goods and other fields. Currently, the shaping and polishing of rubber surfaces mostly relies on semi-automatic machines and manual operation, resulting in low production efficiency. Therefore, achieving fully automated polishing has become an urgent societal need.

[0003] The prior art CN220029597U discloses a trimming device for rubber hose production, including a base, a bracket mounted on the upper surface of the base, the bracket being fixedly connected to the base, a heating frame and a grinding frame mounted in the middle of the bracket, the heating frame being horizontally fixedly mounted on the bracket, the grinding frame being rotatably connected to the bracket, a drive motor for driving the grinding frame to rotate being fixedly mounted on the upper surface of the base, and a winding mechanism being provided at the head of the bracket, the winding mechanism being fixedly connected to the base. This technical solution can achieve the grinding of rubber hoses, but it cannot achieve the fully automated process from automatic sorting to grinding. Utility Model Content

[0004] To solve the above problems, this utility model proposes an automatic rubber tube grinding production line. The line first arranges the rubber tubes neatly in the sorting unit, and then transports the rubber tubes to the grinding unit for grinding through the conveying unit and the loading and unloading unit, thereby completing the fully automated process of rubber tube grinding from sorting to grinding.

[0005] To achieve the above objectives, this technical solution provides an automatic rubber tube polishing production line, including a control system and an aligning unit, a conveying unit, a loading / unloading unit, and a polishing unit, all electrically connected to the control system. The aligning unit, in which rubber tubes are neatly arranged, is located at the beginning of the conveying unit. The end of the conveying unit is connected to the loading / unloading unit. The conveying unit is used to transport the rubber tubes from the beginning to the end. The loading / unloading unit is connected to the polishing unit to transport the rubber tubes to the polishing unit for polishing.

[0006] In this technical solution, a batch of rubber tubes are placed into an aligning unit. Under the coordination of the control system, the aligning unit arranges the disordered rubber tubes neatly in the same direction. Then, the conveying unit transports the rubber tubes one by one to the loading and unloading unit. The loading and unloading unit picks up the rubber tubes and sends them to the grinding unit for grinding, forming a fully automated production process for rubber tubes from aligning, transporting and grinding.

[0007] As a preferred embodiment, the aligning unit includes a feeding rack with a first slope, a vibrating table, and a first conveyor belt. The inner wall of the feeding rack encloses the first slope. The vibrating table is located at the low point of the first slope. The feeding rack has an opening on the side near the vibrating table. The first conveyor belt is located at the opening and connected to the conveying unit. A batch of rubber tubes is poured onto the feeding rack, and the rubber tubes roll along the first slope to the low point. Then, the rubber tubes enter the vibrating table for aligning and sorting. After aligning, they move to the opening and are then neatly conveyed to the conveying unit one by one by the first conveyor belt.

[0008] As a preferred embodiment, the vibration table includes at least one movable step and a first driving device. The movable step is located on one side of the first slope, and the first driving device is located inside the feeding frame. The driving end of the first driving device is connected to the bottom of the movable step to drive the movable step to vibrate up and down. A fixed step is provided on the side of the movable step away from the first slope. The tops of both the movable step and the fixed step are inclined surfaces, and the inclined surfaces are in the same direction as the first slope. Multiple movable steps and fixed steps are arranged alternately in sequence, wherein the height of both the movable steps and the fixed steps increases gradually to one side. The movable steps can move up and down relative to the fixed steps under the drive of the first driving device. The rubber tube first rolls along the first slope to the nearest movable step, and the outer wall of the rubber tube is restricted by the side wall of the fixed step to be neatly arranged in a line. Then the movable step is raised. When the inclined surface of the adjacent movable step rises to be flush with the inclined surface of the fixed step, the rubber tube slides along the inclined surfaces of the movable step and the fixed step to the next movable step. This process is repeated so that the rubber tube is neatly arranged and raised step by step to the opening position.

[0009] As a preferred embodiment, the conveying unit includes a second conveyor belt, a first pushing mechanism, and a first support frame. The second conveyor belt is mounted on the first support frame. The first pushing mechanism is located at the beginning of the second conveyor belt and includes a second driving device, a connecting rod, and a first push plate. The driving end of the second driving device is connected to one end of the connecting rod, and the other end of the connecting rod is fixed to the first push plate so that the first push plate reciprocates along the conveying direction of the second conveyor belt. At the connection between the first and second conveyor belts, the rubber tubes are subjected to forces in two directions and deviate, causing the rubber tubes to be unable to maintain a neat arrangement. The second driving device drives the connecting rod to move, thereby driving the first push plate to reciprocate in parallel. When the rubber tubes enter the second conveyor belt, they are pushed in parallel by the first push plate to correct their posture.

[0010] As a preferred embodiment, the first support frame is further provided with a third conveyor belt connected to the end of the second conveyor belt. The end of the third conveyor belt is inclined upward and connected to the loading and unloading unit. The third conveyor belt is provided with a plurality of equally spaced partitions. The distance between adjacent partitions is equal to the outer diameter of the rubber tube. The first conveyor belt first transports the rubber tube radially to the second conveyor belt. Subsequently, the second and third conveyor belts transport the rubber tube radially to the loading and unloading unit, maintaining the neat arrangement of the rubber tubes during this process. The partitions on the third conveyor belt are used to separate the rubber tubes one by one, ensuring that there is only one rubber tube between adjacent partitions.

[0011] As a preferred embodiment, the loading and unloading unit includes a second support frame, a first telescopic structure, and at least one gripper disposed on the first telescopic structure. The second support frame is provided with a second slope, and the telescopic end of the first telescopic structure is located at the low point of the second slope. The telescopic end of the first telescopic structure performs telescopic movement toward the grinding unit. The high point of the second slope is connected to the end point of the conveying unit. A third transport mechanism conveys the rubber tube to the high point of the second slope. The rubber tube rolls along the second slope to the low point and then falls into the gripper and is held by the gripper.

[0012] As a preferred embodiment, a first guide rail is connected between the loading / unloading unit and the grinding unit. A first sliding member is slidably connected to the first guide rail. The telescopic end of the first telescopic structure is connected to the first sliding member. The gripper is mounted on the first sliding member. The first sliding member drives the first gripper to slide along the first guide rail under the drive of the first telescopic structure.

[0013] As a preferred embodiment, a stop block of equal length to the rubber tube is provided in the middle of the second slope, dividing the second slope into left and right parts. The two grippers correspond to the low points of the two parts of the second slope, respectively. A second pushing mechanism is provided on the second support frame, comprising a second telescopic structure and a second push plate. The second push plate is fixed to the telescopic end of the second telescopic structure, which extends along one side of the stop block to drive the second push plate to push the two rubber tubes towards the two parts of the second slope, respectively. A first guide rod parallel to the second slope is fixed on the second push plate, with both ends extending along the sides of the second push plate. The diameter of the first guide rod is smaller than that of the stop block. The inner diameter of the rubber tubes is such that the stop block acts as a transfer platform, temporarily holding the two rubber tubes in place. Then, the second telescopic structure drives the second push plate to extend and retract. When the second push plate moves forward, it pushes one rubber tube forward to the second slope on the right. When the second push plate moves backward, it pushes the other rubber tube to the second slope on the left. During the movement of the second push plate, the two rubber tubes are respectively fitted onto the two ends of the first guide rod. Because the diameter of the first guide rod is smaller than the inner diameter of the rubber tubes, when the rubber tubes are pushed out, the upper inner wall of the rubber tubes is suspended on the first guide rod. As the second push plate moves in the opposite direction, one end of the rubber tube abuts against the stop block. Under the reaction force of the stop block, the rubber tubes are lowered horizontally. This process ensures the neat arrangement of the rubber tubes.

[0014] As a preferred embodiment, the grinding unit includes a third support frame, a grinding roller, and a fourth driving device. The grinding roller is rotatably mounted on the third support frame, and the driving end of the fourth driving device is connected to the grinding roller. The grinding roller rotates under the drive of the fourth driving device to grind the rubber tube.

[0015] As a preferred embodiment, a discharge box is provided between the loading / unloading unit and the grinding unit. After the rubber tube is ground, the gripper holds the rubber tube on the second guide rod and moves it above the discharge box. Finally, the gripper releases, and the ground rubber tube falls into the discharge box.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention enables the arrangement of rubber tubes through an aligning unit, followed by conveying by a transport unit, and then clamping by an unloading unit to a grinding unit for grinding. This achieves a fully automated production process from aligning and conveying to grinding, resulting in high production efficiency. The aligning unit can uniformly arrange batches of randomly arranged rubber tubes, solving the problem of time-consuming and labor-intensive manual stacking and reducing labor costs. Under the coordination of the control system, the fully automated processes of the aligning, transport, unloading, and grinding units eliminate the need for human intervention, ensuring personnel safety.

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0031] Example 1:

[0032] like Figures 1 to 9As shown, this embodiment provides an automatic rubber tube polishing production line, including a control system and an aligning unit 1, a conveying unit 2, a loading / unloading unit 3, and a polishing unit 4, which are electrically connected to the control system. The aligning unit 1, which arranges the rubber tubes neatly, is located at the beginning of the conveying unit 2. The end of the conveying unit 2 is connected to the loading / unloading unit 3. The conveying unit 2 is used to transport the rubber tubes from the beginning to the end. The loading / unloading unit 3 is connected to the polishing unit 4 to transport the rubber tubes to the polishing unit 4 for polishing.

[0033] In this embodiment, the aligning unit 1, the conveying unit 2, the loading and unloading unit 3, and the grinding unit 4 are electrically connected to the control system. The control system controls the coordinated operation of each unit. The aligning unit 1 is used to arrange a batch of disorderly rubber tubes in a neat manner in the same direction. The conveying unit 2 is used to transport the neatly arranged rubber tubes one by one to the loading and unloading unit 3. The loading and unloading unit 3 can clamp two rubber tubes at a time to the grinding unit 4 for grinding. After grinding, the loading and unloading unit 3 removes the rubber tubes from the grinding unit 4.

[0034] Specifically, the aligning unit 1 includes a feeding rack 11 with a first slope 12, a vibrating table 15, and a first conveyor belt 13. The inner wall of the feeding rack 11 encloses the first slope 12. The vibrating table 15 is located at the lowest point of the first slope 12. The feeding rack 11 has an opening 14 on the side near the vibrating table 15. The first conveyor belt 13 is located at the opening 14 and connected to the conveying unit 2. The vibrating table 15 includes a first driving device 153 with three movable steps. The three movable steps 152 are located at the lowest point of the first slope 12. On one side of the first slope 12, the first driving device 153 is disposed inside the feeding rack 11 and the driving end of the first driving device 153 is connected to the bottom of the movable step 152 to drive the movable step 152 to vibrate up and down. Two fixed steps 151 are arranged in sequence between the three movable steps 152. The two sides of the two fixed steps 151 are respectively connected to the inner walls of the two sides of the feeding rack 11. The tops of the movable steps 152 and the fixed steps 151 are both inclined surfaces, and the inclined surfaces are consistent with the inclination direction of the first slope 12.

[0035] In this embodiment, the width of the fixed adjustment 151 and the movable step 152 is equal to the diameter of the rubber tube, so as to ensure that only one row of rubber tubes in the same direction is on its inclined surface at any time. Each vibration of the movable step 152 can lift a row of rubber tubes to a certain height. Finally, at the position of the highest movable step 152, the tubes fall onto the first conveyor belt 13 of the opening 14. The control system controls the first conveyor belt 13 to run intermittently, transporting one rubber tube to the conveying unit 2 each time.

[0036] Specifically, the conveying unit 2 includes a second conveyor belt 22, a third conveyor belt 23, and a first support frame 21. The second conveyor belt 22 and the third conveyor belt 23 are respectively installed on the first support frame 21. The end of the second conveyor belt 22 is connected to the beginning of the third conveyor belt 23. The end of the third conveyor belt 23 is connected to the loading and unloading unit 3. The third conveyor belt 23 is provided with a plurality of equally spaced partitions 231. The spacing between adjacent partitions 231 is equal to the outer diameter of the rubber tube.

[0037] In this embodiment, the second conveyor belt 22 is set horizontally, and the third conveyor belt 23 is set upwardly for the rubber tube to climb. The partition 231 on the third conveyor belt 23 separates the rubber tubes one by one and transports them to the loading and unloading unit 3 in an orderly manner.

[0038] Specifically, the loading / unloading unit 3 includes a second support frame 31, a first telescopic structure 34, and at least one gripper 36 disposed on the first telescopic structure 34. The second support frame 31 has a second slope 32. The telescopic end of the first telescopic structure 34 is located at the low point of the second slope 32. The telescopic end of the first telescopic structure 34 telescopically extends toward the grinding unit 4. The high point of the second slope 32 is connected to the end point of the conveying unit 2.

The telescopic end of the first telescopic structure 34 is connected to the first sliding member 341. The gripper 36 is mounted on the first sliding member 341. A stop block 33 with a length equal to that of the rubber tube is provided in the middle of the second slope 32. The stop block 33 divides the second slope 32 into left and right parts. The two grippers 36 correspond to the low points of the two parts of the second slope 32, respectively. The second support frame 31 is provided with a second pushing mechanism 35. The second pushing mechanism 35 includes a second telescopic structure 351 and a second push plate 352. The second push plate 352 is fixed to the driving end of the second telescopic structure 351. The driving end of the second telescopic structure 351 moves telescopically along one side of the stop block 33 to drive the second push plate 352 to push the two rubber tubes to the two parts of the second slope 32, respectively. A first guide rod 353 parallel to the second slope 32 is fixed on the second push plate 352. The two ends of the first guide rod 353 extend along both sides of the second push plate 352. The diameter of the first guide rod 353 is smaller than the inner diameter of the rubber tube.

[0039] In this embodiment, the third conveyor belt 23 lifts one rubber tube to the high point of the second slope 32 each time, and then rolls to the stop 33 on the second slope 32 and stops. The second telescopic structure 351 drives the second push plate 352 to push one of the rubber tubes forward. After the second push plate 352 is fully pushed out, the first guide rod 353 on it suspends the rubber tube on the right side of the stop 33. When the second telescopic structure 351 drives the second push plate 352 to move in the opposite direction, the rubber tube is subjected to the reaction force of the right side wall of the stop 33 and disengages from the right guide rod 353 and moves along the right side of the first guide rod 353. The second slope 32 rolls into the right gripper 36. At the same time, the second push plate 352 pushes another rubber tube to the left side of the stop block 33. When the second push plate 352 pushes forward again, the other rubber tube is disengaged from the left guide rod 353 by the reaction force of the left side wall of the stop block 33 and rolls into the left and right grippers 36 on the second slope 32. The left and right grippers 36 clamp the two rubber tubes respectively. The telescopic end of the first telescopic structure 34 drives the two grippers 36 on the first sliding member 341 to move laterally along the first guide rail 342 to the grinding unit 4.

[0040] Specifically, the grinding unit 4 includes a third support frame 41, a grinding roller 42, a fourth drive device 43, a second guide rod 44, a fifth drive device 45, and a translation mechanism 46.

The translation mechanism 46 includes a second guide rail 462, a second sliding member 461, and a sixth drive device 463. The second guide rail 462 is mounted on the third support frame 41. The second sliding member 461 is slidably connected to the second guide rail 462. The sixth drive device 463 is connected to the second sliding member 461 to drive the second sliding member 461 away from or closer to the grinding roller 42. One end of the second guide rod 44 is rotatably connected to the second sliding member 461, and the second guide rod 44 is parallel to the first telescopic structure 34. The fifth drive device 45 is fixed to the second sliding member 461, and the drive end of the fifth drive device 45 is connected to the second guide rod 44.

[0041] In this embodiment, the two grippers 36 respectively attach and release the two rubber tubes onto the second guide rod 44. The two rubber tubes are respectively interference-fitted with the second guide rod 44. The driving end of the fifth driving device 45 and one end of the second guide rod 44 are respectively equipped with pulleys, and a belt is provided between the two pulleys. The fifth driving device 45 drives the second guide rod 44 to rotate via the belt. Under the drive of the sixth driving device 463, the second sliding member 461 drives the second guide rod 44 to translate along the second guide rail 462 to approach the grinding roller 42. The driving end of the fourth driving device 43 and... One end of the grinding roller 42 is provided with a pulley, and a belt is provided between the two pulleys. The fourth drive device 43 is fixed on the second support frame 31 and drives the grinding roller 42 to rotate via the belt to grind the two rubber tubes on the second guide rod 44. After grinding is completed, the sixth drive device 463 drives the second guide rod 44 on the second sliding member 461 to move along the second guide rail 462 away from the grinding roller 42. The fifth drive device 45 stops rotating, and then the two grippers 36 clamp the two rubber tubes again and disengage from the second guide rail 44 with the first sliding member 341.

[0042] In this embodiment, the first drive device 153, the fourth drive device 43, the fifth drive device 45, and the sixth drive device 463 are motors, the first telescopic structure 34 and the second telescopic structure 351 are telescopic cylinders, the sixth drive device 463 can also be a telescopic cylinder, and the gripper 36 is a pneumatic gripper.
