Description

Technical Field

[0001] This utility model relates to the field of rubber roller technology, specifically to a rubber layer removal device for rubber rollers. Background Technology

[0002] Existing rubber rollers consist of a steel core and a rubber layer covering the steel core. During use, the rubber layer inevitably wears and ages, resulting in a limited lifespan for the rubber rollers. To prevent the aging or wear of the rubber rollers from reducing printing quality, it is necessary to replace the non-compliant rubber rollers regularly. Although the replaced rubber rollers cannot be reused, they still have recyclable steel cores. These cores are relatively expensive, and recycling them can save resources.

[0003] A Chinese utility model patent with authorization announcement number CN210361493U discloses a waste rubber roller degumming machine, including a frame and a cutting and peeling assembly. The frame is equipped with a clamp for fixing the rubber roller, and the clamp includes two clamping components that fix both ends of the rubber roller. The cutting and peeling assembly is movably mounted on the frame and includes an annular fixing head and an adjusting device connected to the annular fixing head. The annular fixing head contains a cutting mechanism and a peeling ring located behind the cutting mechanism. The beneficial effects of this technical solution are: the cutting mechanism can cut a notch in the rubber roller, and the peeling ring behind it can lift and peel off the entire rubber layer along the notch, allowing the steel core to be completely recycled. Positioning the peeling ring behind the cutting mechanism ensures that the peeling ring is embedded at the interface between the rubber layer and the steel core, completing the separation of the rubber layer.

[0004] Although the above method can separate the adhesive layer from the steel core, the diameter of the peeling ring cannot be changed, making it impossible to separate the adhesive layer from rollers with different diameters. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rubber layer removal device for a rubber roller. By aligning the two ends of the rubber roller with the middle of two conical funnel-shaped clamping members, the clamping member at the end of the electric push rod pushes the rubber roller to abut against the other clamping member until the rubber roller is fixed between the two clamping members. Under the operation of the second motor, the two clamping members can be driven to drive the rubber roller to rotate at high speed. Under the drive of the sliding device, the rubber rollers on the two vertical plates can be driven to slowly approach the cutting device, so as to achieve the effect of the cutting device removing the rubber layer on the rubber roller.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rubber layer removal device for a rubber roller includes a base. A sliding device is provided on one side of the top of the base. A clamping device is provided on the sliding device. The clamping device includes two upright plates, the bottoms of which are connected to the sliding device. A second motor is provided on the top of one upright plate, and an electric push rod is provided on the top of the other upright plate. The power output ends of the second motor and the electric push rod are arranged opposite each other. A conical funnel-shaped clamping member is provided on both the power output ends of the second motor and the electric push rod. One of the clamping members is rotatably connected to the power output end of the electric push rod. A cutting device adapted to the clamping device is provided on the other side of the top of the base.

[0008] Preferably, the base has sliding grooves on both sides of its top. The sliding device includes a first screw and a sliding rod. The first screw is disposed in one of the sliding grooves, and the sliding rod is disposed in the other sliding groove. A slider is disposed in both sliding grooves. One slider is connected to the first screw through a threaded hole, and the other slider is connected to the sliding rod through a through hole. A first motor for driving the first screw is disposed on one side of the base.

[0009] Preferably, each of the two sliders has a vertical plate at its top, and the two vertical plates are connected at their middle parts by a connecting plate.

[0010] Preferably, the cutting device includes two columns, both of which are located at the end of the slide groove away from the first motor. The top of the two columns is connected by a limiting rod and a second screw. The limiting rod and the second screw are parallel to each other. A moving block is provided on the limiting rod and the second screw. The moving block has a through hole adapted to the limiting rod and a screw hole adapted to the second screw. A cutting blade is provided on the side of the moving block near the vertical plate. A third motor that drives the second screw is provided on one side of one of the columns.

[0011] Preferably, the distance between the two columns is less than the distance between the two plates, a limiting post is provided on one side of the column, the end of the limiting post away from the column is parallel to the cutting edge of the cutting tool, and the horizontal height of the limiting post is the same as the horizontal height of the rubber roller axis.

[0012] Preferably, the cutting tool is detachably mounted on the moving block.

[0013] Preferably, the limiting post is detachably mounted on the column.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model has a simple structure. By aligning the two ends of the rubber roller with the middle of two conical funnel-shaped clamping parts, the clamping part at the end of the electric push rod pushes the rubber roller to abut against the other clamping part until the rubber roller is fixed between the two clamping parts. Since the clamping part at the power output end of the electric push rod is rotatably connected, under the operation of the second motor, the two clamping parts can be driven to drive the rubber roller to rotate at high speed. Under the drive of the sliding device, the rubber rollers on the two vertical plates can be driven to slowly approach the cutting device, so as to achieve the effect of the cutting device removing the rubber layer on the rubber roller. Since both clamping parts are conical funnel-shaped, they can clamp iron cores of different diameters, improving the practicality of this device.

[0016] 2. Under the operation of the third motor, this device can drive the second screw to rotate. The moving block, which is connected to the second screw by a thread, can reciprocate between the two columns with the assistance of the limit rod, so that the cutting blade on the moving block can remove the rubber layer of the entire rubber roller.

[0017] 3. The end of the limiting post on the side of the column can come into contact with the iron core at both ends of the rubber roller when the rubber roller slowly moves towards the cutting blade. When the limiting post comes into contact with the iron core, the first motor stops working. Since the cutting edge of the cutting blade is parallel to the free end of the limiting post, it is easy for the cutting blade to completely remove the rubber layer, while avoiding damage to the iron core.

[0018] 4. This device features a detachable cutting blade, which allows for quick replacement of the cutting blade when its cleaning effect on the adhesive layer decreases, ensuring efficient removal of the adhesive layer from the rubber roller.

[0019] 5. This device, through its detachable mounting limit posts, allows for the replacement of limit posts of different lengths as needed when cutting the rubber layer from rubber rollers with different core diameters. This prevents the cutting blade from damaging the iron core and also avoids the cutting blade from breaking due to contact between the iron core and the cutting blade, thereby improving cutting efficiency and ensuring the service life of the device.

[0023] 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.

[0024] Example 1

[0025] A rubber layer removal device for a rubber roller, with the structure as follows: Figures 1-2 As shown, the device includes a base 1. A sliding device is provided on one side of the top of the base 1. A clamping device is provided on the sliding device. The clamping device includes two upright plates 3. The bottom of both upright plates 3 are connected to the sliding device. A second motor 7 is provided on the top of one upright plate 3, and an electric push rod 8 is provided on the top of the other upright plate 3. The power output end of the second motor 7 and the power output end of the electric push rod 8 are arranged opposite to each other. A conical funnel-shaped clamping member 9 is provided on both the power output end of the second motor 7 and the power output end of the electric push rod 8. One of the clamping members 9 is rotatably connected to the power output end of the electric push rod 8. A cutting device that can be adapted to the clamping device is provided on the other side of the top of the base 1.

[0026] The rubber roller includes an iron core and a rubber layer covering the iron core. When it is necessary to cut the rubber layer off rubber rollers with different iron core diameters and rubber layer thicknesses, the two ends of the rubber roller are aligned with the middle of two conical funnel-shaped clamping parts 9, and the clamping part 9 at the end of the electric push rod 8 pushes the rubber roller to abut against the other clamping part 9 until the rubber roller is fixed between the two clamping parts 9. Since the clamping part 9 at the power output end of the electric push rod 8 is rotatably connected, under the operation of the second motor 7, the two clamping parts 9 can be driven to drive the rubber roller to rotate at high speed. Under the drive of the sliding device, the rubber rollers on the two vertical plates 3 can be driven to slowly approach the cutting device, so as to achieve the effect of the cutting device cutting off the rubber layer on the rubber roller. Since both clamping parts 9 are conical funnel-shaped, they can clamp iron cores of different diameters, improving the practicality of this device.

[0027] The base 1 has sliding grooves 2 on both sides of its top. The sliding device includes a first screw 4 and a slide rod 6. The first screw 4 is installed in one of the sliding grooves 2, and the slide rod 6 is installed in the other sliding groove 2. A slider is installed in both sliding grooves 2. One slider is connected to the first screw 4 through a threaded hole, and the other slider is connected to the slide rod 6 through a through hole. A first motor 5 that drives the first screw 4 is installed on one side of the base 1.

[0028] When it is necessary to activate the sliding device to drive the rubber roller between the two vertical plates 3 to move slowly toward the cutting device, the first motor 5 is turned on. The first motor 5 drives the first screw 4 to rotate slowly. When the first screw 4 rotates, it drives the slider connected to it to move toward the cutting device. When the slider moves, it drives the vertical plate 3 connected to it to move synchronously. Since the rubber roller is fixedly held at the top between the two vertical plates 3, the two vertical plates 3 can move synchronously. The slider on the slide rod 6 moves synchronously with the vertical plate 3 connected to it. The slide rod 6 plays an auxiliary guiding role.

[0029] Each of the two sliders is provided with a vertical plate 3 at its top, and the two vertical plates 3 are connected in the middle by a connecting plate 17.

[0030] Since the vertical plate 3 of the sliding device is connected to the two sliders, the two vertical plates 3 can move synchronously when the threaded rod drives the connected sliders to move. The connecting plate 17 can improve the stability between the two vertical plates 3 and prevent the rubber roller from falling off between the two clamping parts 9.

[0031] The cutting device includes two columns 10, both of which are located at the end of the slide groove 2 away from the first motor 5. The top of the two columns 10 is connected by a limiting rod 11 and a second screw 12. The limiting rod 11 and the second screw 12 are parallel to each other. A moving block 13 is provided on the limiting rod 11 and the second screw 12. The moving block 13 has a through hole adapted to the limiting rod 11 and a screw hole adapted to the second screw 12. A cutting blade 14 is provided on the side of the moving block 13 near the vertical plate 3. A third motor 16 that drives the second screw 12 is provided on one side of one of the columns 10.

[0032] The rubber roller moves slowly toward the cutting device under the operation of the first motor 5. At the same time, the second motor 7 drives the rubber roller to rotate at high speed. Under the operation of the third motor 16, the second screw 12 can be driven to rotate. The moving block 13, which is connected to the second screw 12 by a thread, can move back and forth between the two columns 10 with the assistance of the limit rod 11, so that the cutting blade 14 on the moving block 13 can remove the rubber layer of the entire rubber roller.

[0033] The distance between the two columns 10 is less than the distance between the two upright plates 3. A limiting post 15 is provided on one side of the column 10. The end of the limiting post 15 away from the column 10 is parallel to the cutting edge of the cutting tool 14. The horizontal height of the limiting post 15 is the same as the horizontal height of the rubber roller axis.

[0034] Since the two ends of the rubber roller are usually in contact with mechanical bearings or clamps, they are not covered with a rubber layer. The spacing between the columns 10 can be adapted to the length of the rubber roller covered with a layer. When the rubber roller is cutting off the rubber layer, the end of the limiting post 15 set on the side of the column 10 can abut against the iron core at both ends of the rubber roller when the rubber roller slowly moves towards the cutting blade 14. When the limiting post 15 abuts against the iron core, the first motor 5 stops working. Since the cutting edge of the cutting blade 14 is parallel to the free end of the limiting post 15, it is convenient for the cutting blade 14 to completely cut off the rubber layer, while avoiding damage to the iron core by the cutting blade 14.

[0035] Example 2

[0036] Based on Embodiment 1, the cutting blade 14 is detachably mounted on the moving block 13.

[0037] As the cutting process continues, the cutting edge of the cutting blade 14 will gradually wear down, resulting in a decrease in cutting efficiency. By detaching the cutting blade 14, it is easy to quickly replace the cutting blade 14 when the cleaning effect of the cutting blade 14 on the adhesive layer decreases, thus ensuring the efficiency of removing the adhesive layer on the rubber roller.

[0038] The limiting post 15 is detachably installed on the column 10.

[0039] Since there are many types of rubber rollers, when the diameter of the rubber-coated iron core is larger than the diameter of the uncoated iron cores at both ends, and the free end of the limiting post 15 is parallel to the cutting edge of the cutting blade 14, the limiting post 15 cannot contact the iron cores at both ends of the rubber roller when the cutting blade 14 contacts the rubber-coated iron core. The cutting blade 14 will damage the rubber-coated iron core. By detachably installing the limiting post 15, when cutting the rubber layer on the surface of this type of rubber roller, the limiting post 15 of different lengths can be replaced according to the required size to avoid damage to the iron core by the cutting blade 14. It also avoids the cutting blade 14 from breaking due to contact between the iron core and the cutting blade 14, thereby improving the cutting efficiency and ensuring the service life of the device.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations, additions, subtractions, or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
