Description

Technical Field

[0001] This utility model belongs to the technical field of tire production equipment, specifically an automatic opening and closing device for the chuck of the engineering tire oil skin taking station. Background Technology

[0002] Bias-ply tire oil layer is a rubber layer located on the inner surface of the inner tube of a bias-ply tire. Its main function is to prevent moisture, air, and impurities from seeping into the tire carcass ply layer. These seepage substances may negatively affect the tire's performance and service life. At the same time, the oil layer also protects the inner tube from wear and tear on the ply layer, thereby extending the inner tube's service life.

[0003] When producing bias tire rubber on the inner liner line of the engineering tire workshop, after winding the rubber at the rubber winding station, the chuck needs to be opened to change the roll. Currently, iron blocks are used to manually knock open the chucks on both sides of the station to lift out the rubber roll. There is no platform on the other side of the rubber roll for the operator to stand on. The operator has to use a long iron roller or stand on the winding conveyor belt to knock the chuck open. This increases the labor intensity of the operators, and each time the iron block is used to knock, it is easy to damage the equipment. Therefore, this needs to be improved. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides an automatic opening and closing device for a chuck at an engineering tire oil wrapping station, including a fixed plate 1. A fixed shaft 2 is fixedly installed on the top right side of the front end of the fixed plate 1. A long arm 3 is movably sleeved on the outer surface of the fixed shaft 2. A round shaft 4 is movably sleeved inside the left end of the long arm 3. A slide rod 5 is movably sleeved on the rear side inside the round shaft 4. The rear end of the slide rod 5 passes through the round shaft 4 and extends to the outside of the round shaft 4, where a chuck 6 is fixedly installed. A groove 7 is formed on the outer surface of the chuck 6. A locking block 8 is movably sleeved on the left and right sides of the bottom end of the groove 7. There are two blocks 8. Connecting rods 9 are movably connected inside the two blocks 8. There are two connecting rods 9, and they are the same in shape and size. A first mounting plate 11 is fixedly installed at the bottom left of the front end of the long arm 3, located in front of the connecting rod 9. There are two first mounting plates 11. Opening and closing cylinders 10 are fixedly installed at the front ends of the two first mounting plates 11. There are two opening and closing cylinders 10. The rear ends of the two opening and closing cylinders 10 are fixedly connected to the front ends of the two connecting rods 9 respectively. A manual valve 12 is fixedly installed at the bottom front end of the fixed plate 1.

[0023] The manual valve 12 has two air outlets and one air inlet. The two air outlets of the manual valve 12 are connected to the air inlets of the two opening and closing cylinders 10 through air ducts, respectively. Thus, the operation of the two opening and closing cylinders 10 can be controlled by operating the manual valve 12. Both opening and closing cylinders 10 are short-stroke thin-walled cylinders ADVC-32-15, and their stroke is the same as the opening and closing stroke of the chuck 6. In this way, when producing bias tire rubber, the chuck 6 can be opened and the reel can be changed by controlling the extension and retraction of the opening and closing cylinders 10 through the manual valve 12, thereby reducing the labor intensity of the operator and avoiding equipment damage caused by hitting with iron blocks.

[0024] Among them, a circular block 13 is fixedly sleeved on the outer surface of the circular shaft 4, the rear end of the circular block 13 is movably connected to the front end of the long arm 3, a fixed frame 14 is movably sleeved on the outer surface of the circular block 13, the inner surface of the front end of the fixed frame 14 is movably sleeved with the outer surface of the circular shaft 4, and the rear end of the fixed frame 14 is fixedly connected to the front end of the long arm 3.

[0025] The cooperation between the circular block 13 and the fixed frame 14 will limit the circular shaft 4, thereby preventing the circular shaft 4 from detaching and falling.

[0026] Among them, the front ends of the two locking blocks 8 are respectively movably connected to baffles 15, the inner surface of baffles 15 and the outer surface of connecting rod 9 are fixedly sleeved, and the top of the inner surface of the two locking blocks 8 are respectively provided with slots 16, and inserts 17 are movably sleeved inside the slots 16. The bottom end of the insert 17 passes through the connecting rod 9 and extends into the interior of the connecting rod 9.

[0027] The presence of baffle 15 will block and limit the movement of the locking block 8, while the presence of slot 16 and insert 17 will connect and lock the locking block 8 and the connecting rod 9.

[0028] Among them, the bottom end of the insert block 17 is fixedly installed with a movable block 18. The outer surface of the movable block 18 is movably sleeved with the top of the inner surface of the connecting rod 9. The inside of the movable block 18 is movably sleeved with a limit rod 19. The upper and lower ends of the limit rod 19 are fixedly connected to the upper and lower inner walls of the connecting rod 9, respectively. The bottom end of the movable block 18 is fixedly installed with a spring 20 located outside the limit rod 19. The other end of the spring 20 is fixedly connected to the bottom of the inner surface of the connecting rod 9.

[0029] When the movable block 18 moves along the outer surface of the limiting rod 19, it will compress the spring 20. Under the restoring action of the spring 20, the movable block 18 will be forced to return to its original position along with the insert block 17.

[0030] An extension rod 21 is fixedly installed at the middle of the bottom of the movable block 18. The bottom end of the extension rod 21 passes through the connecting rod 9 and extends to the outside of the connecting rod 9, and a handle 22 is fixedly installed thereon. The top end of the handle 22 is movably connected to the outer surface of the connecting rod 9.

[0031] When the handle 22 is pulled, the handle 22 will move along the inner surface of the connecting rod 9 via the extension rod 21, along with the movable block 18 and the insert block 17, and compress the spring 20.

[0032] Among them, a fixing block 23 located between two opening and closing cylinders 10 is fixedly installed on the left side of the bottom end of the long arm 3, and a short shaft 24 is fixedly sleeved inside the fixing block 23.

[0033] The presence of the fixing block 23 and the short shaft 24 will serve to connect and fix the long arm 3.

[0034] Among them, the bottom of the left front end of the fixed plate 1 is movably sleeved with a second mounting plate 27 located below the short shaft 24. The top of the second mounting plate 27 is fixedly installed with a lifting cylinder 26. The top of the lifting cylinder 26 is fixedly installed with a connecting block 25. The inner surfaces of the front and rear ends of the connecting block 25 are movably sleeved with the front and rear sides of the outer surface of the short shaft 24, respectively. The inner surface of the connecting block 25 is movably sleeved with the outer surface of the fixed block 23.

[0035] The air inlet on the manual valve 12 is connected to the air inlet pipe of the lifting cylinder 26 through the air pipe. When the lifting cylinder 26 is started, the long arm 3 will rotate around the long arm 3 as the axis under the action of the short shaft 24, the connecting block 25 and the fixing block 23.

[0036] Working principle and usage process of this utility model:

[0037] When changing the roll of oil-coated film, the operator opens the manual valve 12 to retract the opening and closing cylinder 10. At this time, the connecting rod 9 will move the locking block 8 under the action of the opening and closing cylinder 10, so that the locking block 8 will generate a pushing force on the inner wall of the groove 7, pushing the chuck 6 and the sliding rod 5 to move towards the round shaft 4, thereby opening the chuck 6. After the chuck 6 is opened, the operator can lift out the roll. After the roll is replaced, the operator controls the opening and closing cylinder 10 to extend through the manual valve 12 to close the chuck 6. In this way, the opening and closing of the chuck 6 can be realized through the cooperation of the manual valve 12, the opening and closing cylinder 10, the connecting rod 9 and the locking block 8, thereby reducing the labor intensity of the operator and avoiding damage to the equipment caused by hitting with iron blocks.

[0038] When the locking block 8 is severely worn and needs to be replaced, the operator pulls the handle 22, causing the extension rod 21 to move along with the movable block 18 and the insert block 17, compressing the spring 20 until the insert block 17 separates from the slot 16, releasing the lock of the insert block 17 on the locking block 8 and the connecting rod 9. Then the operator rotates the locking block 8, and after the locking block 8 separates from the groove 7, the locking block 8 can be removed for replacement. This improves the convenience of disassembling and replacing the locking block 8, thereby preventing the locking block 8 from being severely worn and affecting the opening and closing operation of the chuck 6.
