Description

Technical Field

[0001] This utility model belongs to the field of continuous structure technology, and in particular relates to a rubber roller assembly for EVA film production with a quick-change adhesive layer. Background Technology

[0002] In the production of EVA film, the rubber roller assembly is a key component, and its performance directly affects product quality and production efficiency. Replacing the rubber layer on traditional rubber roller assemblies is often cumbersome and time-consuming, and improper operation during replacement can easily damage or loosen the assembly, thus affecting the stable operation of the production line.

[0003] According to a public disclosure (CN111232758B), a textile rubber roller with a quick-disassembly and replacement rubber layer includes an adjusting roller core, a sliding end block, a rubber layer, and a screw end block. The sliding end block is slidably disposed inside one end of the rubber layer, and the screw end block is interference-fitted into the other end of the rubber layer. The adjusting roller core includes a roller core body, one end of which is threaded into the screw end block, and the other end of which is slidably disposed inside the sliding end block. This invention uses the adjusting roller core and the screw end block to cooperate. The screw-fitting protrusion of the screw end block cooperates with the rotating connecting rod of the roller core body to support and lock one end of the adjusting roller core. The other end of the adjusting roller core is supported and locked by the cooperation of the adjusting screw and the rotating push rod, forming a complete rubber roller. This design provides more stable force distribution, convenient disassembly and assembly, and quick replacement of damaged rubber layers.

[0004] In the aforementioned application, the quick disassembly and replacement of the adhesive layer is achieved through the cooperation of components such as adjusting roller core, sliding end block, and screw end block. Although this improves the replacement efficiency to a certain extent, its structure is relatively complex and may not be entirely suitable for rubber roller assemblies used in EVA film production. Therefore, we propose a rubber roller assembly for EVA film production that can quickly replace the adhesive layer. Utility Model Content

[0005] The purpose of this invention is to provide a rubber roller assembly for EVA film production with a quick-change adhesive layer. By cooperating with the fixed plate, auxiliary plate and threaded rod in the adjustable locking device, the problem of existing rubber roller assemblies being unable to be quickly replaced and the replacement process being cumbersome and complicated is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a rubber roller assembly for EVA film production with quick-change adhesive layer, including a rotating shaft, a rubber sleeve provided on the circumferential surface of the rotating shaft, and an adjustable locking device provided on the circumference of the rotating shaft.

[0008] The adjustable locking device includes a fixed plate, which is fixedly connected to the inner wall of the rotating shaft. The fixed plate passes through and is fixedly connected to the circumferential surface of the rotating shaft. An auxiliary plate is fixedly connected to the inner wall of the rotating shaft. A threaded rod is rotatably connected to the side of the auxiliary plate. A manual column is fixedly connected to one end of the threaded rod. A connecting rod one is hinged to the circumferential surface of the threaded rod by a threaded sleeve. A connecting rod two is hinged to the end of the connecting rod one away from the threaded sleeve. A hinge block is hinged to the end of the connecting rod two away from the connecting rod one. A fixing groove is formed on the circumferential surface of the rotating shaft.

[0009] Furthermore, a stabilizing sleeve is rotatably connected to the circumferential surface of the rotating shaft, and the bottom of the stabilizing sleeve is fixedly connected to the inner bottom of the rotating shaft. A buffer pad is fixedly connected to the side of the second connecting rod. Its function is to buffer and protect the second connecting rod by the buffer pad when the threaded rod is rotated, so as to avoid damage caused by friction between the second connecting rod and the rotating shaft, thereby improving the service life of the rubber roller assembly.

[0010] Furthermore, the circumferential surface of the manual column is rotatably connected to the inner wall of the rotating shaft, and the inner side of the fixing groove is slidably connected to the side of the connecting rod one. Its function is to increase the stability of the equipment, and the connecting rod one and the connecting rod two play a locking role.

[0011] Furthermore, the end of the rubber sleeve away from the fixed plate is located on the displacement trajectory of the side of the buffer pad, and the side section of the threaded rod is set in a convex shape, which is to facilitate the user to drive the threaded rod to rotate by manually rotating the rod, while preventing the threaded rod from falling off during rotation.

[0012] Furthermore, the inner wall of the rotating shaft is provided with a lubrication and maintenance device, which includes an oil tank fixedly connected to the inner wall of the rotating shaft. The oil tank is filled with oil cotton, and the inner wall of the oil tank has an oil drip port. A pressure rod is fixedly connected to the side of the threaded sleeve. Its function is to squeeze the oil cotton through the pressure rod during the movement of the threaded sleeve, so that the lubricating oil inside the oil cotton drips through the oil drip port onto the surface of the threaded rod, thereby lubricating the threaded rod and the threaded sleeve and increasing the stability of the equipment.

[0013] Furthermore, the side of the oil tank penetrates the circumference of the threaded rod, and the oil cotton is designed to be circular, which facilitates the rotation of the oil cotton inside the oil tank and increases the contact area between the oil cotton and the threaded rod, thereby improving the lubrication effect.

[0014] Furthermore, the circumferential surface of the pressure rod penetrates the bottom of the oil tank, and the bottom of the oil cotton is located on the displacement trajectory of the end of the pressure rod away from the threaded sleeve. Its function is to facilitate the pressure rod to squeeze the oil cotton during the movement, so that the lubricating oil inside the oil cotton can drip fully onto the surface of the threaded rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves rapid replacement of the rubber sleeve through the cooperation of components such as the fixing plate, auxiliary plate, and threaded rod in the adjustable locking device, while ensuring stability and convenience during the replacement process. During use, when the rubber sleeve needs to be replaced, the user only needs to manually rotate the threaded rod. The rotation of the threaded rod moves the threaded sleeve, thereby locking and unlocking, increasing the practicality of the device.

[0017] 2. This utility model achieves automatic lubrication and maintenance between the threaded rod and threaded sleeve through the cooperation of components such as the oil tank, oil cotton, and oil drip nozzle in the lubrication and maintenance device. This avoids jamming between the threaded rod and threaded sleeve caused by prolonged use, thus improving the smoothness of the rubber roller assembly. At the same time, the inclusion of components such as the oil tank, oil cotton, and oil drip nozzle makes the lubrication and maintenance process simpler and more convenient, eliminating the need for additional manual lubrication operations and saving labor and time costs.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model is a rubber roller assembly for EVA film production with quick-change adhesive layer, including a rotating shaft 1, a rubber sleeve 2 provided on the circumferential surface of the rotating shaft 1, and an adjustable locking device 3 provided on the circumference of the rotating shaft 1.

[0029] The adjustable locking device 3 includes a fixing plate 301, which is fixedly connected to the inner wall of the rotating shaft 1. The fixing plate 301 passes through and is fixedly connected to the circumferential surface of the rotating shaft 1. An auxiliary plate 302 is fixedly connected to the inner wall of the rotating shaft 1. A threaded rod 303 passes through and is rotatably connected to the side of the auxiliary plate 302. A manual column 304 is fixedly connected to one end of the threaded rod 303. A connecting rod 306 is hinged to the circumferential surface of the threaded sleeve 305. A connecting rod 307 is hinged to the end of the connecting rod 306 away from the threaded sleeve 305. A hinge block 308 is hinged to the end of the connecting rod 307 away from the connecting rod 306. A fixing groove 309 is provided on the circumferential surface of the rotating shaft 1.

[0030] As shown in the figure, a stabilizing sleeve 4 is rotatably connected to the circumferential surface of the rotating shaft 1. The bottom of the stabilizing sleeve 4 is fixedly connected to the inner bottom of the rotating shaft 1. A buffer pad 5 is fixedly connected to the side of the connecting rod 307. Its function is to buffer and protect the connecting rod 307 through the buffer pad 5 when the threaded rod 303 is rotated, so as to avoid damage caused by friction between the connecting rod 307 and the rotating shaft 1, thereby improving the service life of the rubber roller assembly.

[0031] As shown in the figure, the circumferential surface of the manual column 304 is rotatably connected to the inner wall of the rotating shaft 1, and the inner side of the fixing groove 309 is slidably connected to the side of the connecting rod 306. Its function is to increase the stability of the equipment. The connecting rod 306 and the connecting rod 307 play a locking role.

[0032] As shown in the figure, the end of the rubber sleeve 2 away from the fixed plate 301 is located on the displacement trajectory of the side of the buffer pad 5. The side section of the threaded rod 303 is set in a convex shape, which is to facilitate the user to drive the threaded rod 303 to rotate through the manual column 304, while preventing the threaded rod 303 from falling off during rotation.

[0033] As shown in the figure, a lubrication and maintenance device 6 is provided on the inner wall of the rotating shaft 1. The lubrication and maintenance device 6 includes an oil tank 601, which is fixedly connected to the inner wall of the rotating shaft 1. An oil cotton 602 is provided inside the oil tank 601, and an oil dripping port 603 is opened on the inner wall of the oil tank 601. A pressure rod 604 is fixedly connected to the side of the threaded sleeve 305. Its function is to squeeze the oil cotton 602 through the pressure rod 604 during the movement of the threaded sleeve 305, so that the lubricating oil inside the oil cotton 602 drips through the oil dripping port 603 onto the surface of the threaded rod 303, thereby lubricating the threaded rod 303 and the threaded sleeve 305 and increasing the stability of the equipment.

[0034] As shown in the figure, the side of the oil tank 601 penetrates the circumference of the threaded rod 303. The oil cotton 602 is circular, which facilitates the rotation of the oil cotton 602 inside the oil tank 601 and increases the contact area between the oil cotton 602 and the threaded rod 303, thereby improving the lubrication effect.

[0035] As shown in the figure, the circumferential surface of the pressure rod 604 penetrates the bottom of the oil tank 601, and the bottom of the oil cotton 602 is located on the displacement trajectory of the end of the pressure rod 604 away from the threaded sleeve 305. Its function is to facilitate the pressure rod 604 to squeeze the oil cotton 602 during the movement, so that the lubricating oil inside the oil cotton 602 can drip fully onto the surface of the threaded rod 303.

[0036] A specific application of this embodiment is as follows: When it is necessary to replace the rubber sleeve 2 of the rubber roller assembly, the user first manually rotates the manual column 304. The manual column 304 drives the threaded rod 303 to rotate. Since the circumferential surface of the threaded rod 303 is threadedly connected to the circumferential surface of the threaded sleeve 305, the threaded rod 303 drives the threaded sleeve 305 to move during rotation. During the movement of the threaded sleeve 305, the connecting rod 306 moves, which in turn drives the connecting rod 307 to move. The connecting rod 307 then drives the hinge block 308 to move, causing the hinge block 308 to return to the inside of the fixing groove 309. At this time, the rubber sleeve 2 can be disassembled and replaced. After the rubber sleeve 2 is replaced, the user rotates the manual column 304 in the opposite direction. The manual column 304 drives the threaded rod 303 to rotate in the opposite direction. The threaded rod 303 drives the threaded sleeve 305 to move in the opposite direction. The threaded sleeve 305 drives the connecting rod 1 306 to move in the opposite direction. The connecting rod 1 306 drives the connecting rod 2 307 to move in the opposite direction. The connecting rod 2 307 drives the hinge block 308 to move in the opposite direction until the buffer pad 5 presses against the rubber roller. At this time, the fixed installation of the rubber sleeve 2 is completed. During the movement of the threaded sleeve 305, the threaded sleeve 305 drives the pressure rod 604 to move. The pressure rod 604 squeezes the oil cotton 602, so that the lubricating oil inside the oil cotton 602 drips through the oil dripping port 603 onto the surface of the threaded rod 303, lubricating the threaded rod 303 and the threaded sleeve 305, and increasing the stability of the equipment.
