Description

Technical Field

[0001] This utility model relates to the technical field of rubber roller processing equipment, specifically to a rubber coating mechanism for rubber rollers. Background Technology

[0002] Rubber rollers are roller-shaped products made by vulcanizing rubber with metal or other materials as the core. They are widely used in printing, papermaking, textile and other industries. In the production process of rubber rollers, the rubber coating process is one of the key links, and its quality directly affects the performance and life of the rubber roller. Therefore, it is particularly important to develop a rubber coating mechanism for rubber rollers.

[0003] A coating machine for rubber rollers, as described in reference announcement number CN212472374U, includes a cutting mechanism for cutting rubber strips, a rotating mechanism, a fixed frame, and a rubber roller. The cutting mechanism is located at the rear of the fixed frame, the rotating mechanism is located at the middle of the rear of the fixed frame, and the rubber roller is located at the rear of the fixed frame. The cutting mechanism is positioned above the rubber roller. It also includes a rubber supply mechanism for supplying rubber strips. This coating mechanism uses a second auxiliary roller to press the rubber sheet onto the rubber roller, allowing the rubber sheet to adhere to the entire outer side of the rubber roller, thus eliminating gaps between the rubber sheet and the rubber roller and improving the bonding quality. A cutter and cutter holder can quickly cut the rubber sheet, ensuring a uniform and neat interface, facilitating the bonding of the rubber strip to the next rubber roller. While this coating mechanism has good application capabilities, it is generally not convenient for quick disassembly and assembly of the rubber roller, making roller replacement somewhat inconvenient and requiring further improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a rubber coating mechanism for rubber rollers, so as to solve the problem that although the rubber coating mechanism mentioned in the background art can be well applied, it is usually not convenient to quickly disassemble and assemble the rubber roller, which makes it inconvenient to replace the rubber roller.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating mechanism for a rubber roller, comprising a cabinet, rollers installed at the corners of the bottom of the cabinet, a stand installed on one side of the top of the cabinet, a positioning seat provided on one side of the top of the stand, a bearing seat provided at the upper end of the positioning seat, both ends of the bearing seat extending to the outside of the positioning seat, an L-shaped frame provided at the top of the stand on one side of the positioning seat, a motor installed on the outer wall of the L-shaped frame, a rotating shaft installed at the output end of the motor via a coupling, the end of the rotating shaft away from the motor passing through the bearing seat and having a threaded shaft, a fixed sleeve fixedly installed on the outer wall of one side of the threaded shaft, a rubber roller component sleeved on the outer wall of the threaded shaft on one side of the fixed sleeve, a movable threaded sleeve threadedly installed on the outer wall of the threaded shaft on the side of the rubber roller component away from the fixed sleeve, a plurality of rotating handles installed on the outer wall of the movable threaded sleeve, a control panel installed at the upper end of the surface of the cabinet, the output end of the microcontroller inside the control panel being electrically connected to the input end of the motor.

[0006] Preferably, a side frame is provided on one side of the outer wall of the cabinet, and a roll unwinding roller is rotatably installed on the outer wall of the side frame away from the cabinet. The roll unwinding roller is provided to wind and place the rubber strip.

[0007] Preferably, a horizontal plate is provided on the outer wall of the side connecting frame below the unwinding roller, and a U-shaped frame is provided above the horizontal plate. A limiting roller is rotatably installed on the inner wall of the U-shaped frame. The limiting roller is used to limit the rubber strip wound on the outer wall of the unwinding roller.

[0008] Preferably, a plurality of telescopic rods are installed at the top of the horizontal plate, the top of the telescopic rods are connected to the bottom of the U-shaped frame, and springs are wound around the outer wall of the telescopic rods. The springs are designed to work with the telescopic rods to apply an upward elastic pressure to the U-shaped frame.

[0009] Preferably, a mounting base is provided on the outer wall of the cabinet on one side of the roller, and a nut is provided on one side inside the mounting base to accommodate the screw.

[0010] Preferably, the nut has a screw thread installed on its internal thread, the top end of the screw extends to the outside of the nut and is fitted with a handle, and the bottom end of the screw extends to the outside of the nut and is fitted with an anti-slip foot. The anti-slip foot is provided to prevent the rubber coating mechanism from slipping.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the rubber coating mechanism for rubber rollers not only achieves the purpose of easy disassembly and replacement of rubber roller parts, but also reduces the phenomenon of rubber strips loosening and falling off on the outer wall of the unwinding roller, and ensures the stability of the rubber coating mechanism during use.

[0012] (1) By rotating the rotating handle, the moving threaded sleeve is rotated and slid on the outer wall of the threaded shaft. When the moving threaded sleeve is screwed away from the outer wall of the threaded shaft, the rubber roller can be removed from the outer wall of the threaded shaft. When the moving threaded sleeve is screwed into the outer wall of the threaded shaft, the moving threaded sleeve and the fixed sleeve can be used to fit the rubber roller onto the outer wall of the threaded shaft, thereby achieving the purpose of easy disassembly and replacement of the rubber roller.

[0013] (2) The spring has good elasticity, so that it works with the telescopic rod to apply upward elastic pressure to the U-shaped frame. The limiting roller can elastically limit the rubber strip wound on the outer wall of the unwinding roller, thereby reducing the phenomenon of the rubber strip loosening and falling off on the outer wall of the unwinding roller.

[0014] (3) By rotating the handle, the drive screw is rotated and slid inside the nut, so that the screw drives the anti-slip foot to move up and down. When the anti-slip foot moves down and contacts the ground, the entire rubber coating mechanism can be anti-slip, which can effectively reduce the displacement of the rubber coating mechanism and ensure the stability of the rubber coating mechanism during use.

[0022] In use, the unwinding roller 16 is used to wind and arrange the rubber strip.

[0023] A horizontal plate 17 is provided on the outer wall of the side connecting frame 15 below the unwinding roller 16, and a U-shaped frame 18 is provided above the horizontal plate 17. A limit roller 19 is rotatably installed on the inner wall of the U-shaped frame 18.

[0024] In use, the limiting roller 19 is set to limit the rubber strip wound on the outer wall of the unwinding roller 16.

[0025] Several telescopic rods 20 are installed at the top of the horizontal plate 17. The top of the telescopic rods 20 is connected to the bottom of the U-shaped frame 18. Springs 21 are wound around the outer wall of the telescopic rods 20.

[0026] In use, the spring element 21 is provided so that it can work with the telescopic rod 20 to apply an upward elastic pressure to the U-shaped frame 18;

[0027] Rollers 2 are installed at the corners at the bottom of the cabinet 1. A component holder 22 is provided on the outer wall of the cabinet 1 on one side of the roller 2. A nut 23 is provided on one side inside the component holder 22.

[0028] In use, the screw 24 is positioned by setting the nut 23;

[0029] The nut 23 has a screw 24 installed on its internal thread. The top end of the screw 24 extends to the outside of the nut 23 and is fitted with a handle 26. The bottom end of the screw 24 extends to the outside of the nut 23 and is fitted with an anti-slip foot 25.

[0030] In use, the anti-slip feet 25 are provided to prevent the rubber coating mechanism from slipping.

[0031] A stand 4 is installed on one side of the top of the cabinet 1. A positioning seat 5 is provided on one side of the top of the stand 4. A bearing seat 6 is provided at the upper end of the interior of the positioning seat 5. Both ends of the bearing seat 6 extend to the outside of the positioning seat 5. An L-shaped frame 7 is provided at the top of the stand 4 on one side of the positioning seat 5. A motor 8 is installed on the outer wall of the L-shaped frame 7. A rotating shaft 9 is installed at the output end of the motor 8 through a coupling. The end of the rotating shaft 9 away from the motor 8 passes through the bearing seat 6 and is provided with a threaded shaft 10. A fixed sleeve 12 is fixedly installed on the outer wall of one side of the threaded shaft 10. A rubber roller 11 is sleeved on the outer wall of the threaded shaft 10 on one side of the fixed sleeve 12.

[0032] A movable threaded sleeve 13 is threadedly installed on the outer wall of the threaded shaft 10 on the side of the rubber roller 11 away from the fixed sleeve 12. Several rotating handles 14 are installed on the outer wall of the movable threaded sleeve 13. A control panel 3 is installed on the upper end of the surface of the cabinet 1. The output terminal of the microcontroller inside the control panel 3 is electrically connected to the input terminal of the motor 8.

[0033] In this embodiment, several rollers 2 are first used to drive the coating mechanism for conveying and transferring. Then, by rotating the handle 26, the drive screw 24 rotates and slides inside the nut 23, causing the screw 24 to move the anti-slip foot 25 up and down. When the anti-slip foot 25 touches the ground, the entire coating mechanism is anti-slip, improving its stability. Next, the rubber strip is wound and placed on the outer wall of the unwinding roller 16, with one end connected to the outer wall of the rubber roller 11. When the motor 8 is started, it drives the rubber roller 11 to rotate via the rotating shaft 9 and the threaded shaft 10, thus coating the rubber strip onto the outer wall of the rubber roller 11. The spring 21 provides good elasticity, ensuring proper contact. The telescopic rod 20 applies upward elastic pressure to the U-shaped frame 18, which allows the limiting roller 19 to elastically limit the rubber strip wound on the outer wall of the unwinding roller 16, reducing the possibility of the rubber strip loosening and falling off the outer wall of the unwinding roller 16. Finally, the movable threaded sleeve 13 is rotated by the handle 14, causing the movable threaded sleeve 13 to rotate and slide on the outer wall of the threaded shaft 10. When the movable threaded sleeve 13 is screwed away from the outer wall of the threaded shaft 10, the rubber roller 11 can be removed from the outer wall of the threaded shaft 10. When the movable threaded sleeve 13 is screwed into the outer wall of the threaded shaft 10, the movable threaded sleeve 13, in conjunction with the fixed sleeve 12, can fit the rubber roller 11 onto the outer wall of the threaded shaft 10, making it easy to disassemble and replace the rubber roller 11, thus completing the use of the rubber coating mechanism.
