Description

Technical Field

[0001] This utility model relates to the field of gravure printing roller technology, and in particular to a high-strength, deformation-resistant gravure printing roller. Background Technology

[0002] A gravure printing roller is a type of roller used for printing and coating. It is usually made of hollow metal tubes with patterns of a certain depth and shape engraved on its surface. These patterns are usually various types of grooves or holes. These grooves or holes play a key role in the printing process, as they can compact ink, paint or glue and make it more uniform and aesthetically pleasing during printing or coating.

[0003] In high-speed printing, existing gravure printing rollers are prone to deformation and wear on their surface due to insufficient mechanical strength and processing precision. This leads to a decline in print quality, reduced roller lifespan, increased printing costs, and reduced printing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength, deformation-resistant gravure printing roller.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength, deformation-resistant gravure printing roller, comprising a gravure printing roller body and two round shafts. Support and reinforcement devices are respectively provided between the inner walls of both ends of the gravure printing roller body and the outer surfaces of the two round shafts. Each support and reinforcement device includes two screw-hole discs and several support plates. A detachable device is provided between the outer surface of the screw-hole discs and the inner wall of the gravure printing roller body. A U-shaped block is symmetrically fixedly connected to one side of each support plate. A connecting rod is rotatably connected to the inner wall of the U-shaped block. A threaded sleeve is fixedly connected to the outer surface of each round shaft. The outer surface of the threaded sleeve is threadedly connected to the inner wall of the screw-hole discs. A round hole block is rotatably connected to one end of the threaded sleeve. Several grooves are formed on the outer surface of the round hole block. The inner wall of the grooves is rotatably connected to one end of the connecting rod. Several first telescopic rods are fixedly connected to one side of the round hole block. One end of each first telescopic rod is fixedly connected to one side of the screw-hole discs. The outer surface of the support plate abuts against the inner wall of the gravure printing roller body.

[0006] The effects achieved by the above-mentioned components are as follows: By setting up a support and reinforcement device, before using the gravure printing roller body for high-speed printing, the screw hole discs are first installed in the inner walls of both ends of the gravure printing roller body using a detachable device. Then, the gravure printing roller body is fixed in place. At the same time, the two threaded sleeves and the round shaft are held and moved threadedly to one end in the inner walls of the two screw hole discs to a certain position. Under the limiting action of the first telescopic rod, the round hole block can be driven to move to one end with the threaded sleeves. This pushes several connecting rods to rotate in the inner walls of the grooves and U-shaped blocks, while the support plate is pushed outward, so that one side of it abuts against the inner wall of the gravure printing roller body, thus supporting and reinforcing its inner wall. This can increase the overall strength of the gravure printing roller body, avoid deformation and damage during use, improve printing quality and printing efficiency, increase the service life of the gravure printing roller, reduce printing costs, and by adjusting the distance between the several support plates, the inner wall of the gravure printing roller body with different diameters can be supported and reinforced.

[0007] Preferably, a plurality of reinforcing rods are fixedly connected to the outer surface of one end of the first telescopic rod, and one side of the reinforcing rod is fixedly connected to one side of the circular hole block.

[0008] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the first telescopic rod and one side of the circular hole block can be increased, making the connection more secure and stable, and less prone to breakage or damage.

[0009] Preferably, a plurality of screw blocks are fixedly connected to the outer surface of one end of the threaded sleeve, and the plurality of screw blocks are arranged at equal intervals.

[0010] The effect achieved by the above components is that by setting the screw block, the contact area of ​​the outer surface of one end of the threaded sleeve can be increased, making it easier to manually screw it.

[0011] Preferably, a bearing is fixedly connected to the inner wall of the circular hole block, and the inner ring of the bearing is fixedly connected to the outer surface of one end of the threaded sleeve.

[0012] The effect achieved by the above components is that by setting bearings, the contact wear between the round hole block and the outer surface of the threaded sleeve can be reduced, thereby increasing the service life of both.

[0013] Preferably, the detachable device includes several locking rods, several sliding grooves are provided on one side of the screw hole disc, a spring is fixedly connected to one side of the inner wall of the sliding groove, one end of the spring is fixedly connected to one side of the locking rod, several slots are provided on the inner walls of both ends of the gravure printing roller body, and one end of the locking rod passes through one side of the sliding groove and is inserted into the inner wall of the slot.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up a detachable device, when it is necessary to maintain or replace the support plate and threaded sleeve, the locking rod can be manually slid to one end in the inner wall of the slide groove to a certain position, causing the spring to contract and pulling one end of the locking rod out of the slot, thereby releasing the limit between the screw hole disc and the gravure printing roller body. Then, by holding the round shaft and pulling it to one end, the screw hole disc can be removed from the inner wall of the gravure printing roller body, which facilitates the maintenance and replacement of several support plates and threaded sleeves.

[0015] Preferably, a plurality of anti-slip blocks are fixedly connected to both sides of one end of the clamp rod, and the anti-slip blocks are made of rubber.

[0016] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction on both sides of one end of the lever can be increased, making it less likely to slip when manually gripped and pulled.

[0017] Preferably, limit blocks are fixedly connected to both sides of the lever, and limit grooves are formed on both sides of the inner wall of the slide groove, with the limit blocks and limit grooves slidably connected.

[0018] The effect achieved by the above components is that by setting limit blocks and limit grooves, the two sides of the lever can be limited, so that it is not easy to wobble left and right when sliding back and forth.

[0019] Preferably, a second telescopic rod is fixedly connected to one side of the inner wall of the slide groove, one end of the second telescopic rod is fixedly connected to one side of the clamping rod, and the outer surface of the second telescopic rod is sleeved and connected to the inner wall of the spring.

[0020] The effect achieved by the above components is that by setting a second telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use and increasing its service life.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting up a support and reinforcement device, before using the gravure printing roller body for high-speed printing, the screw hole discs are first installed in the inner walls of both ends of the gravure printing roller body using a detachable device. Then, the gravure printing roller body is fixed in place. At the same time, two threaded sleeves and a round shaft are held and moved threadedly to one end in the inner walls of the two screw hole discs. This can drive the round hole block to move to one end, pushing the support plate outward and abutting against the inner wall of the gravure printing roller body, increasing the overall strength of the gravure printing roller body, avoiding deformation and damage during use, improving printing quality and printing efficiency, increasing the service life of the gravure printing roller, reducing printing costs, and by adjusting the distance between several support plates, the inner wall of the gravure printing roller body with different diameters can be supported and reinforced.

[0029] Example 1, such as Figure 1-5As shown, a high-strength, deformation-resistant gravure printing roller includes a gravure printing roller body 1 and two round shafts 4. Support and reinforcement devices 2 are provided between the inner walls of both ends of the gravure printing roller body 1 and the outer surfaces of the two round shafts 4. Each support and reinforcement device 2 includes two screw-hole discs 211 and several support plates 21.

The outer surface of the round shafts 4... A threaded sleeve 24 is fixedly connected to the surface. The outer surface of the threaded sleeve 24 is threadedly connected to the inner wall of the screw hole disc 211. A round hole block 25 is rotatably connected to one end of the outer surface of the threaded sleeve 24. Several grooves 26 are opened on the outer surface of the round hole block 25. The inner wall of the grooves 26 is rotatably connected to one end of the connecting rod 23. Several first telescopic rods 27 are fixedly connected to one side of the round hole block 25. One end of the first telescopic rod 27 is fixedly connected to one side of the screw hole disc 211. The outer surface of the support plate 21 abuts against the inner wall of the gravure printing roller body 1. Before using the gravure printing roller body 1 for high-speed printing, the screw hole discs 211 are first installed in the inner walls of both ends of the gravure printing roller body 1 using the detachable device 3. Then, the gravure printing roller body 1 is fixed in place. At the same time, the two threaded sleeves 24 and the round shaft 4 are held and moved threadedly to one end in the inner walls of the two screw hole discs 211 to a certain position. Under the limiting action of the first telescopic rod 27, the round hole block 25 can be driven to move to one end with the threaded sleeves 24, pushing several connecting rods 23 in the groove 26 and the U-shaped block 2. While rotating within the inner wall of the printing roller 2, the support plate 21 is pushed outward, so that one side of it abuts against the inner wall of the gravure printing roller body 1, thus supporting and reinforcing its inner wall. This increases the overall strength of the gravure printing roller body 1, preventing deformation and damage during use, improving printing quality and efficiency, increasing the service life of the gravure printing roller, and reducing printing costs. Furthermore, by adjusting the distance between several support plates 21, the inner wall of the gravure printing roller body 1 with different diameters can be supported and reinforced.

By setting the reinforcing rods 28, the connection area between the first telescopic rod 27 and one side of the circular hole block 25 can be increased, making the connection more firm and stable, and less prone to breakage or damage. A plurality of screwing blocks 29 are fixedly connected to the outer surface of one end of the threaded sleeve 24, and the plurality of screwing blocks 29 are arranged at equal intervals. By setting the screwing blocks 29, the contact area of ​​the outer surface of one end of the threaded sleeve 24 can be increased, making it easier to manually screw it.

Several sliding grooves 31 are opened on one side of the screw hole plate 211. A spring 32 is fixedly connected to one side of the inner wall of the sliding groove 31. One end of the spring 32 is fixedly connected to one side of the locking rod 33. Several slots 38 are opened on the inner walls of both ends of the gravure printing roller body 1. One end of the locking rod 33 passes through one side of the sliding groove 31 and is inserted into the inner wall of the slot 38. When maintenance and replacement of support plate 21 and threaded sleeve 24 are required, the locking rod 33 can be manually slid to one end in the inner wall of the slide groove 31 to a certain position, causing the spring 32 to contract and pull one end of the locking rod 33 out of the slot 38, thereby releasing the limit between the screw hole disc 211 and the gravure printing roller body 1. Then, hold the round shaft 4 and pull it to one end, thereby removing the screw hole disc 211 from the inner wall of the gravure printing roller body 1, which facilitates the maintenance and replacement of several support plates 21 and threaded sleeves 24.

[0033] Reference Figure 4 and Figure 5 As shown, this embodiment discloses that a plurality of anti-slip blocks 34, made of rubber, are fixedly connected to both sides of one end of the lever 33. By setting the anti-slip blocks 34, the contact friction between the two sides of one end of the lever 33 can be increased, making it less likely to slip when manually gripped and pulled. Limiting blocks 35 are fixedly connected to both sides of the lever 33, and limiting grooves 36 are formed on both sides of the inner wall of the slide groove 31. The limiting blocks 35 and the limiting grooves 36 are slidably connected. By setting the limiting blocks 35 and the limiting grooves 36, the two sides of the lever 33 can be limited, making it less likely to wobble left and right when sliding back and forth. A second telescopic rod 37 is fixedly connected to one side of the inner wall of the slide groove 31.

[0034] Working principle: Before high-speed printing using the gravure printing roller body 1, the screw hole discs 211 are first installed in the inner walls of both ends of the gravure printing roller body 1 using the detachable device 3. Then, the gravure printing roller body 1 is fixed in place. At the same time, the two threaded sleeves 24 and the round shaft 4 are held and moved threadedly to one end in the inner walls of the two screw hole discs 211 to a certain position. Under the limiting action of the first telescopic rod 27, the round hole block 25 can be driven to move to one end with the threaded sleeves 24, pushing several connecting rods 23 in the groove 26 and U-shaped... While the inner wall of block 22 rotates, the support plate 21 is pushed outward, so that one side of it abuts against the inner wall of the gravure printing roller body 1, thus supporting and reinforcing its inner wall. This increases the overall strength of the gravure printing roller body 1, prevents deformation and damage during use, improves printing quality and efficiency, increases the service life of the gravure printing roller, and reduces printing costs. Furthermore, by adjusting the distance between several support plates 21, the inner wall of the gravure printing roller body 1 with different diameters can be supported and reinforced.

[0035] When maintenance and replacement of support plate 21 and threaded sleeve 24 are required, the locking rod 33 and limiting block 35 can be manually slid to a certain position in the inner wall of slide groove 31 and limiting groove 36 respectively, causing spring 32 and second telescopic rod 37 to retract, and causing one end of locking rod 33 to be pulled out of locking groove 38, thereby releasing the limiting between screw hole disc 211 and gravure printing roller body 1. Then, hold the round shaft 4 and pull it to one end, thereby removing screw hole disc 211 from the inner wall of gravure printing roller body 1, which facilitates maintenance and replacement of several support plates 21 and threaded sleeve 24.
