Description

Technical Field

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

[0002] Rubber-coated rollers are widely used as tension rollers, steering rollers, squeezing rollers, support rollers, and conveying rollers. Rubber rollers are also called rubber-coated roller shafts. They are cylindrical rotating bodies made of metal materials, and then a layer of rubber material is coated on the surface of the cylindrical rotating body. A rubber coating device is required for rubber rollers.

[0003] For example, a rubber roller coating device with authorization announcement number "CN 218803506 U" designs the internal parts of a horizontal and vertical adjustment mechanism controlled by a control panel. This allows for the adjustment of the rubber roller's position based on existing conditions and the required thickness of the coating material, meeting various requirements. The adjustment is motor-controlled, ensuring consistent horizontal and vertical movement to prevent inconsistent movement due to manual adjustment, which could cause the rubber roller to shift and affect subsequent coating operations. However, when applying adhesive to the roller surface using a tape, deviations can easily occur during movement, leading to coating failure and reducing the coating quality. Furthermore, after coating, operators need to manually press the coated area, increasing workload and reducing the device's efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems that when the device applies glue to the surface of the glue roller via the tape, deviations easily occur during the movement, leading to glue application failure, which reduces the glue application quality of the device. Also, after the device has applied glue, the operator needs to manually press the glued area, which increases the operator's workload and reduces the working efficiency of the device. Therefore, a glue roller coating device is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rubber roller coating device is designed, including a base and a first outer shell. The first outer shell is fixedly connected to the upper end of the base. The coating device is provided inside the first outer shell. A support plate is provided above the first outer shell. A frame is fixedly connected to the upper left side of the support plate. The frame contains adhesive tape. A pressing device is provided on the upper right side of the support plate.

[0007] Preferably, the coating device includes a first motor and a first gear. The first motor is fixedly connected to the first housing via a bracket. The output shaft of the first motor is rotatably connected to the first housing via a bearing. The first gear is fixedly connected to the output shaft of the first motor. The outer wall of the first gear meshes with a second gear. A threaded rod is fixedly connected to the inner wall of the second gear. The outer wall of the threaded rod is threadedly connected to a threaded plate.

[0008] Preferably, the two ends of the threaded rod are rotatably connected to the first housing via bearings, the outer wall of the threaded plate is slidably connected to the first housing, and a support plate is fixedly connected to the upper end of the threaded plate.

[0009] Preferably, a fixing plate is fixedly connected to both sides of the upper end of the first housing. The left side of the fixing plate is fixedly connected to the second motor via a bracket. The output shaft of the second motor is rotatably connected to the fixing plate via a bearing. A rubber roller is fixedly connected to the output shaft of the second motor.

[0010] Preferably, the clamping device includes a second housing and a fixing rod. The bottom of the second housing is fixedly connected to a support plate, and the fixing rod is fixedly connected to the right side of the inner wall of the second housing. A spring is provided on the outer wall of the fixing rod, and the two ends of the spring are fixedly connected to the second housing and the sliding plate, respectively. A pressure plate is fixedly connected to the left end of the sliding plate.

[0011] Preferably, the outer wall of the fixing rod is slidably connected to the slide plate, the outer wall of the slide plate is slidably connected to the second outer shell, and the outer wall of the pressure plate is slidably connected to the second outer shell.

[0012] The present invention provides a rubber roller coating device with the following advantages: Through the cooperation of the coating device and the rubber roller, the output shaft of the first motor rotates, driving the first gear to rotate. Since the first gear has fewer teeth than the second gear, the rotation of the first gear simultaneously drives the second gear to achieve deceleration. The rotation of the second gear drives the threaded rod to rotate synchronously at a reduced speed. The rotation of the threaded rod causes the threaded plate to move slowly. Simultaneously, the movement of the threaded plate drives the upper frame and the rubber belt to move. The rubber belt coats the rubber roller while moving. The deceleration transmission of the first and second gears drives the rubber belt to coat the rubber roller, making its movement more precise, avoiding deviations during movement that could lead to coating failure, and improving the coating quality.

[0013] With the cooperation of the pressing device and the rubber roller, after the rubber roller surface is coated with rubber, the diameter of the coated rubber roller becomes larger than before. When it comes into contact with the pressure plate, it squeezes the pressure plate, causing the pressure plate to be subjected to pressure into the second housing. The pressure plate retracts into the second housing, and the pressure plate drives the sliding plate to move synchronously. The sliding plate compresses the spring, and under the reaction force of the spring, it pushes the sliding plate and the pressure plate outward. The pressure plate continuously presses against the surface of the coated rubber roller, thereby squeezing and pressing the rubber on the surface of the rubber roller. It no longer requires manual pressing by the operator, reducing the workload of the operator and improving work efficiency. Attached Figure Description

The left side of the fixing plate 9 is fixedly connected to the second motor 8 via a bracket. The second motor 8 is designed to meet the actual working requirements. The output shaft of the second motor 8 is rotatably connected to the fixing plate 9 via bearings. A rubber roller 10 is fixedly connected to the output shaft of the second motor 8. The output shaft of the second motor 8 is fixed to the rotating shaft of the rubber roller 10 via bolts to facilitate subsequent disassembly of the rubber roller 10. The rotation of the output shaft of the second motor 8 drives the rubber roller 10 to rotate. The outer wall of the fixing rod 302 is slidably connected to the slide plate 304. The outer wall of the slide plate 304 is slidably connected to the second housing 301. The outer wall of the pressure plate 305 is slidably connected to the second housing 301.

[0024] See attached document Figure 1-5 The coating device 2 includes a first motor 201 and a first gear 202. The first motor 201 is designed to meet the actual working requirements. The first motor 201 is fixedly connected to the first housing 4 via a bracket. The output shaft of the first motor 201 is rotatably connected to the first housing 4 via a bearing. The first gear 202 is fixedly connected to the output shaft of the first motor 201. The number of teeth of the first gear 202 is less than that of the second gear 203. The outer wall of the first gear 202 meshes with the second gear 203. The rotation of the first gear 202 drives the second gear 203 to rotate slowly, thereby achieving a deceleration effect. A threaded rod 204 is fixedly connected to the inner wall of the second gear 203. The outer wall of the threaded rod 204 is threadedly connected to a threaded plate 205. The rotation of the threaded rod 204 drives the threaded plate 205 to move.

[0025] See attached document Figure 3 and 6 The clamping device 3 includes a second housing 301 and a fixing rod 302. The bottom of the second housing 301 is fixedly connected to the support plate 5. The fixing rod 302 is fixedly connected to the right side of the inner wall of the second housing 301. A spring 303 is provided on the outer wall of the fixing rod 302. The elastic coefficient of the spring 303 can be determined according to actual requirements to meet the working needs. The two ends of the spring 303 are fixedly connected to the second housing 301 and the slide plate 304 respectively. A pressure plate 305 is fixedly connected to the left end of the slide plate 304. The slide plate 304 drives the pressure plate 305 to move synchronously.

[0026] Working principle:

[0027] The operator installs the tape 7 inside the frame 6, attaches one end of the tape 7 to the surface of the rubber roller 10, connects the external power supply of the second motor 8, starts the output shaft of the second motor 8 to rotate and drive the rubber roller 10 to rotate, and then starts the rubber coating device 2 to work, so that the threaded rod 204 drives the rubber coating device 2 and the pressing device 3 above to move synchronously. The rubber coating device 2 coats the rubber roller 10 with rubber, and the pressing device 3 presses the rubber roller 10 after rubber coating.

[0028] The process of coating rubber rollers:

[0029] When the external power supply of the first motor 201 is connected, the output shaft of the first motor 201 is started to rotate, which drives the first gear 202 to rotate. Since the number of teeth of the first gear 202 is less than that of the second gear 203, the rotation of the first gear 202 drives the second gear 203 to achieve deceleration. The rotation of the second gear 203 drives the threaded rod 204 to rotate synchronously at a reduced speed. The rotation of the threaded rod 204 drives the threaded plate 205 to move slowly. While the threaded plate 205 is moving, it drives the upper frame 6 and the tape 7 to move. The tape 7 moves while wrapping the rubber roller 10 with rubber, completing the process of wrapping the rubber roller.

[0030] The process of pressing the rubber coating onto the rubber roller:

[0031] After the rubber roller 10 is coated with rubber, its diameter becomes larger than before. When it comes into contact with the pressure plate 305, it squeezes the pressure plate 305, causing the pressure plate 305 to be subjected to pressure into the second housing 301. The pressure plate 305 retracts into the second housing 301, and the pressure plate 305 drives the sliding plate 304 to move synchronously. The sliding plate 304 compresses the spring 303, and at the same time, under the reaction force of the spring 303, it pushes the sliding plate 304 and the pressure plate 305 outward. The pressure plate 305 continuously presses against the surface of the rubber roller 10 after coating, thereby squeezing and pressing the rubber on the surface of the rubber roller 10, completing the pressing process of coating the rubber roller. After pressing is completed, the rubber roller 10 can be removed by disassembling the bolt between the output shaft of the second motor 8 and the rubber roller 10, so that a new rubber roller can be replaced for coating.
