Description

Technical Field

[0001] The invention relates to the technical field of valve separation, in particular to a device for efficiently separating waste inner tube valves. Background Art

[0002] At present, the function of the valve is to inflate and deflate the tire, and to maintain the seal of the tire after inflation. In the production of tire inner tubes, when the inner tube is unqualified and needs to be recycled, the connection between the inner tube and the valve needs to be heated, and then the valve can be separated from the inner tube. The valve is separated for recycling, and the inner tube is re-mixed and extruded.

[0003] In the prior art, for unqualified inner tubes, the connection between the valve and the inner tube is usually heated manually by a nozzle hotter, and then the valve is manually pulled off the inner tube.

[0004] The above-mentioned prior art solutions have the following defects: only the valve of an unqualified inner tube can be recycled individually, but the valves of multiple inner tubes cannot be recycled at the same time, and the separation efficiency of the valve and the inner tube is slow. Summary of the invention

[0005] The purpose of the invention is to provide a waste inner tube valve mouth high-efficiency separation device which can improve the separation efficiency of the valve mouth and the inner tube.

[0006] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0007] A waste inner tube valve efficient separation device comprises a heating device, wherein the heating device comprises a heating pipe and a heating column, a heat medium passes through the heating pipe, a plurality of heating columns are arranged, the heating columns are fixedly connected to the heating pipe, and the heating columns pass through the heating pipe, the heating columns are perpendicular to the heating pipe, and a placement hole is opened in the heating column, and the axis of the placement hole coincides with the axis of the heating column.

[0008] By adopting the above technical solution, the heating pipe heats the heating column, and the heating column passes through the heating pipe, so that the contact area between the heating column and the heat medium in the heating pipe is larger, so that the heat medium can heat the heating column more quickly, and the valve nozzle is inserted into the placement hole, so that the connection between the valve nozzle and the inner tube is abutted against the end face of the heating column, and the valve nozzle and the inner tube are hung on the heating column. The placement hole plays a role in placing and fixing the valve nozzle, and it is no longer necessary to manually hold the valve nozzle and the inner tube for operation. The heating column heats the connection position between the valve nozzle and the inner tube, and the connection position between the valve nozzle and the inner tube is heated and the bonding firmness gradually loosens. As the bonding between the inner tube and the valve nozzle As the firmness decreases, the gravity of the inner tube drives it to gradually fall and separate from the valve stem until the inner tube falls and is completely separated from the valve stem. At this time, the valve stem is still in the placement hole, and the valve stem is manually taken out of the placement hole to complete the recovery of the valve stem. The arrangement of multiple heating columns allows a valve stem to be placed in each heating column, that is, multiple valve stems can be separated at the same time, thereby improving the separation efficiency of the valve stem and the inner tube. During the entire separation process, only manual insertion of the valve stem into the placement hole and removal of the separated valve stem are required. There is no need to manually hold the valve stem and the inner tube for heating and separation, thereby reducing the waste of human resources.

[0009] The present invention is further configured as follows: an outer wall of the heating pipe is provided with a heat-insulating layer, a protective layer is provided outside the heat-insulating layer, and the distance between the end of the heating column away from the heating pipe is not less than the distance between the protective layer and the heating pipe.

[0010] By adopting the above technical scheme, the insulation layer plays an insulating role for the heating pipe and the heating column, so that the heat loss is less, the heat loss is reduced, the temperature of the end of the heating column away from the heating pipe is ensured, and it is ensured that it can heat the valve stem and the inner tube; the protective layer protects the insulation layer and the heating pipe inside it, avoiding the heating pipe from being accidentally damaged.

[0011] The present invention is further configured such that the angle between the axis of the heating column and the horizontal direction away from the heating pipe is not less than zero degree and not more than forty-five degrees.

[0012] By adopting the above technical solution, after the valve mouth is inserted into the placement hole, the valve mouth will not gradually tilt downward in the direction away from the heating pipe, and the valve mouth will not slip out of the placement hole, thereby ensuring the stability of the valve mouth in the placement hole.

[0013] The present invention is further configured as follows: a flaring groove is provided at the end of the heating column away from the heating pipe, and the flaring groove extends from the placement hole toward the axial direction away from the placement hole, so that the heating column is flared from the inner wall of the placement hole to the end of the heating column.

[0014] By adopting the above technical solution, the setting of the expansion groove makes the opening of the placement hole away from the end of the heating pipe larger, which is convenient for placing the valve mouth into the placement hole.

[0015] The present invention is further configured as follows: the heating pipes are arranged in two rows arranged vertically, one ends of the two rows of heating pipes are connected, and the heating columns on the two heating pipes are staggered in the horizontal direction.

[0016] By adopting the above technical solution, the two rows of heating pipes are arranged so that the number of heating columns on each heating pipe will not be too large, ensuring that each heating column can be heated to a certain temperature, so that there is sufficient temperature to separate the valve stem from the inner tube; the heating columns on the two heating pipes are staggered in the horizontal direction, so that the inner tubes placed on the two heating pipes will not interfere with each other, and the inner tubes can fall separately, ensuring the smooth separation of the inner tube and the valve stem.

[0017] The present invention is further configured as follows: a receiving groove is provided below the heating pipe, and the top of the receiving groove gradually tilts downward in a direction gradually away from the heating pipe along the axis of the heating column.

[0018] By adopting the above technical scheme, the receiving groove can receive the falling inner tube, thus preventing the inner tube from falling to the ground and getting dirty and inconvenient to recover. The inclined setting of the top of the receiving groove enables the higher part of the receiving groove to better limit the inner tube, ensuring that the inner tube can fall into the receiving groove, while the lower side makes it more convenient for people to take the inner tube.

[0019] The present invention is further configured as follows: a removal component is provided at the end of the heating pipe, and the removal component includes a bracket, a sliding column and a removal plate. The bracket is frame-shaped, and two brackets and two sliding columns are each provided and are respectively located at the two ends of the heating pipe. The sliding column is horizontally slidably connected to the inner side of the bracket, and the sliding direction of the sliding column is perpendicular to the axis of the heating pipe. The removal plate is vertically slidably connected between the two sliding columns.

[0020] By adopting the above technical scheme, when all the inner tubes connected to the valves in the heating columns connected to the same heating pipe have fallen off, the sliding column is moved toward the heating column and in the direction away from the end of the heating pipe, and then the removal plate is moved vertically downward so that the removal plate presses the valves tightly. The heated end of the valves has a certain viscosity and can stick to the removal plate. The removal plate is moved in the direction away from the heating column, and the valves are taken away from the placement holes by the removal plate, so that a whole row of valves can be removed at the same time without taking the valves out of the placement holes one by one, thereby improving work efficiency.

[0021] The present invention is further configured as follows: a horizontal scraping assembly is arranged on the top of the heating pipe, the scraping assembly includes a support plate, a scraper and a scraping spring, the support plate is located above the heating pipe, the support plate is horizontally arranged, both ends of the support plate are fixedly connected to the side of the bracket facing the support plate, the scraper is located above the support plate and is slidably connected to the support plate, the sliding direction of the scraper is horizontal and perpendicular to the axis of the heating pipe, the scraper spring is fixedly connected between the scraper and the support plate, the length direction of the scraper spring is horizontal and perpendicular to the axis of the heating pipe, and the scraper spring is fixedly connected to the vertical side of the scraper away from the heating column.

[0022] By adopting the above technical solution, after the removal plate sticks the valve mouth out of the placement hole, the removal plate is moved vertically upward, and the side of the removal plate facing the scraper plate abuts against the scraper plate, so that the valve core stuck on the removal plate is scraped off by the scraper plate and then falls into the receiving groove, ensuring that the valve core can fall from the removal plate; and the setting of the hanging spring makes the scraper plate scrape the removal plate more smoothly without damaging the valve mouth.

[0023] The present invention is further configured as follows: a vertical placement groove is opened in the bracket, a fixed block is vertically slidably connected in the placement groove, a fixing spring is fixedly connected between the top of the fixing block and the bracket, a through hole is opened in the bracket, the opening direction of the through hole is parallel to the sliding direction of the sliding column, the bottom of the placement groove is connected to the through hole, and the sliding column is fixedly connected with a clamping block that is adapted to the through hole and can be clamped by the fixed block.

[0024] By adopting the above technical solution, the movement of the movable plate drives the sliding column to move. When the sliding column moves away from the side close to the bracket, the fixed block is inserted into the through hole. As the sliding column continues to move, the clamping block lifts the fixed block, and then the fixed block clamps the clamping block, so that the clamping block and the sliding column will not continue to move, thereby ensuring the stability of the sliding column.

[0025] The present invention is further configured such that: the upper surface of the scraper is fixedly connected to a limiting block.

[0026] By adopting the above technical solution, when the removal plate moves to the top of the scraper and continues to move in the direction away from the heating column, the movable plate drives the limit block to move together, thereby moving along with the limit plate, the scraper spring is compressed, and when the removal plate needs to be moved, the fixed block is moved upward, and the fixed block will no longer play a fixing role on the card block. The scraper spring gives the scraper plate an elastic force to move, and the scraper gives the removal plate an outward elastic force through the limit block, so that the removal plate can be moved away from the fixed block with less effort.

[0027] In summary, the beneficial technical effects of the present invention are:

[0028] 1. By setting a heating device, multiple valves can be separated at the same time, which improves the separation efficiency of the valve and the inner tube;

[0029] 2. By setting up the removal assembly, a whole row of valves can be removed at the same time, without having to remove the valves from the placement holes one by one, thus improving work efficiency;

[0030] 3. By setting the limit block, it is easier to move the removal plate away from the fixed block. BRIEF DESCRIPTION OF THE DRAWINGS

The support frame 111 is fixedly connected to the ground. The support frame 111 supports the heating pipe 11. A heat medium is passed through the heating pipe 11. The heating medium can be water vapor or the like. The temperature of the heating medium is 100-130°C, which is lower than the vulcanization temperature of the inner tube. A plurality of heating columns 12 are arranged. The heating columns 12 are fixedly connected to the heating pipe 11, and the heating columns 12 pass through the heating pipe 11. The heating columns 12 are perpendicular to the heating pipe 11.

In this embodiment, the heating column 12 is arranged horizontally and perpendicular to the heating pipe 11. The heating column 12 is provided with a horizontal placement hole 121. The axis of the placement hole 121 coincides with the axis of the heating column 12. A flaring groove 122 is provided at the end of the heating column 12 away from the heating pipe 11, and the axis of the flaring groove 122 coincides with the axis of the heating column 12. The flaring groove 122 extends from the placement hole 121 to the axis direction away from the placement hole 121, so that the heating column 12 gradually flares from the inner wall of the placement hole 121 to the end of the heating column 12, so that the opening at the end of the heating column 12 is larger, and in the process of the valve nozzle being placed into the placement hole 121, the flaring groove 122 guides the valve nozzle, making it easy to place the valve nozzle into the placement hole 121.

As the bonding strength between the inner tube and the valves decreases, the gravity of the inner tube drives it to gradually fall and gradually separate from the valves, until the inner tube falls and is completely separated from the valves. The arrangement of multiple heating columns 12 can separate multiple valves at the same time, thereby improving the separation efficiency of the valves and the inner tubes.

[0044] Reference Figure 1 As shown in Figure 5, a removal component 4 is provided at the end of the heating pipe 11, and the removal component 4 includes a bracket 41, a sliding column 42 and a removal plate 43. The bracket 41 is frame-shaped, and the axis of the heating pipe 11 is perpendicular to the bracket 41. Two brackets 41 and two sliding columns 42 are provided and are respectively located at both ends of the heating pipe 11. The bracket 41 is fixedly connected to the two sides of the support frame 111 that are opposite to each other. The sliding column 42 is horizontally slidably connected to the inner side of the bracket 41, and the sliding direction of the sliding column 42 is perpendicular to the axis of the heating pipe 11. The removal plate 43 is vertically slidably connected between the two sliding columns 42, and the removal plate 43 is parallel to the end face of the heating column 12. A vertical placement slot 411 is provided in the bracket 41, and a fixing block 412 is vertically slidably connected in the placement slot 411. A fixing spring 413 is fixedly connected between the top of the fixing block 412 and the bracket 41. A through hole 414 is provided in the bracket 41. The opening direction of the through hole 414 is parallel to the sliding direction of the sliding column 42. The bottom of the placement slot 411 is connected to the through hole 414. The sliding column 42 is fixedly connected with a block 421 that is adapted to the through hole 414 and can be clamped by the fixing block 412. Along the direction approaching the sliding column 42, the block 421 gradually tilts upward away from the side of the sliding column 42. A groove 422 is provided on the upper surface of the block 421. The bottom end of the fixing block 412 gradually tilts upward along the direction approaching the side of the sliding column 42. When the inner tube is separated from the valve, the fixing block 412 is moved upward, the fixing block 412 leaves the clamping slot, the block 421 is no longer limited by the fixing block 412, and moves horizontally out of the plate 43 (refer to Figure 6 ), the removal plate 43 drives the sliding column 42 to move together, and then moves the removal plate 43 downward, and then the removal plate 43 is abutted against the valve nozzle, the valve nozzle sticks to the removal plate 43, and the removal plate 43 is moved away from the heating column 12, and the removal plate 43 drives the valve nozzle to separate from the heating column 12.

[0045] Reference Figure 3 and Figure 4A horizontal scraping assembly 5 is provided on the top of the heating pipe 11. The scraping assembly 5 includes a support plate 51, a scraper 52 and a scraper spring 53. The support plate 51 is located above the heating pipe 11. The support plate 51 is horizontally arranged. Both ends of the support plate 51 are fixedly connected to the side of the bracket 41 facing the support plate 51. The scraper 52 is located above the support plate 51 and is slidably connected to the support plate 51. The sliding direction of the scraper 52 is horizontal and perpendicular to the axis of the heating pipe 11. The scraper spring 53 is fixedly connected between the scraper 52 and the support plate 51. The length direction of the scraper spring 53 is horizontal and perpendicular to the axis of the heating pipe 11. line, the scraper spring 53 is fixedly connected to the vertical side of the scraper 52 away from the heating column 12, and a slide groove 522 is opened on the lower surface of the scraper 52. The slide groove 522 starts from the end of the scraper 52 away from the scraper spring 53 and stops near the end of the scraper 52 close to the scraper spring 53. The upper surface of the support plate 51 is fixedly connected with a slide bar 511. When the slide bar 511 is stuck in the slide groove 522 near the bottom of the spring at the fixed position, the scraper spring 53 is in a compressed state, so that the scraper 52 can give a certain scraping force to the removal plate 43 to ensure that the valve mouth can be scraped off. The upper surface of the scraper 52 is fixedly connected to the limiting block 521. Move the removal plate 43 with the valve stem stuck to it upwards, and the scraper 52 scrapes the valve stem off. After moving the removal plate 43 to the top of the scraper 52, move the removal plate 43 horizontally. When the removal plate 43 moves to the position of the limit block 521, the limit block 521 is driven to move together with the scraper 52 until the fixing block 412 is stuck in the groove 422.

[0046] The implementation principle of this embodiment is: insert the valve into the placement hole 121, so that the connection position of the valve and the inner tube is abutted against the end face of the heating column 12, and the valve and the inner tube are hung on the heating column 12, and the heating pipe 11 heats the heating column 12, and the heating column 12 heats the connection position of the valve and the inner tube. The connection position of the valve and the inner tube is heated and the bonding strength gradually becomes loose. As the bonding strength between the inner tube and the valve decreases, the gravity of the inner tube drives it to gradually fall and gradually separate from the valve, until the inner tube falls and the inner tube is completely separated from the valve. The provision of multiple heating columns 12 allows a valve to be placed in each heating column 12, that is, multiple valves can be separated at the same time, thereby improving the separation efficiency of the valve and the inner tube.

[0047] At this time, the valve is still located in the placement hole 121, and the fixing block 412 is moved upward. The fixing block 412 will not continue to fix the block 421. The scraper spring 53 gives the scraper 52 an elastic force to move, and the scraper 52 gives the removal plate 43 an outward elastic force through the limit block 521, so that the removal plate 43 moves to the end of the scraper 52, and then the removal plate 43 is moved vertically downward until the removal plate 43 moves to the bottom of the scraper 52, and then the removal plate 43 is moved horizontally in the direction close to the heating column 12, and the removal plate 43 is abutted against the end of the valve. Then the heated valve has a certain viscosity, and the valve sticks to the removal plate 43. Then the removal plate 43 is moved away from the heating column 12, and then the removal plate 43 is moved vertically upward. When the removal plate 43 passes the scraper 52, the side of the removal plate 43 with the valve stuck to it is scraped The plate 52 abuts, and the valve mouth is scraped off by the scraper 52. The scraped valve mouth falls into the receiving groove 3, ensuring that the valve mouth can be completely separated from the removal plate 43; until the scraped valve mouth falls into the receiving groove 3, the removal plate 43 moves to the top of the scraper 52, and the removal plate 43 is moved in the direction close to the limit block 521. After the removal plate 43 contacts the limit block 521, the limit block 521 and the scraper 52 are driven to move together, the scraping spring 53 is compressed, and the removal plate 43 moves horizontally, driving the sliding column 42 to move horizontally together. When the blocking block 421 is inserted into the through hole 414 and is stuck by the fixed block 412, the sliding column 42 and the removal plate 43 will not continue to move, so that a whole row of valve mouths can be removed at the same time without taking the valve mouths out of the placement hole 121 one by one, thereby improving work efficiency.

[0048] During the entire separation process, only the valve nozzle needs to be manually inserted and placed in the placement hole 121, and then the valve nozzle of the only same heating pipe 11 is removed by removing the plate 43. It is no longer necessary to manually hold the valve nozzle and the inner tube for heating and separation, thus reducing the waste of human resources.

[0049] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
