Description

Technical Field

[0001] This utility model relates to the field of printing technology, specifically to a precision single-color double-sided roller printing device. Background Technology

[0002] In today's ever-evolving printing industry, single-color double-sided roller printing equipment plays a crucial role. It can quickly and efficiently complete single-color double-sided printing, meeting the requirements of brochures, packaging boxes, and other products for double-sided printing effects and precision. It is a powerful tool for improving printing quality.

[0003] When using a traditional single-color double-sided roller printing device, the printing roller is first installed and its relative position to the roller shaft is adjusted. The paper is then fed between the printing rollers along a set path. The rotation of the roller shaft drives the printing roller, and the ink supply completes the single-color double-sided printing process.

[0004] However, existing single-color double-sided roller printing devices still have certain limitations in use. When replacing the printing roller according to printing needs, the operator must first remove the fasteners at one end, leaving one end of the printing roller suspended in the air, and then manually support it to remove it from the machine body to complete the subsequent operation. During the operation, a large number of peripheral parts need to be disassembled and installed, which is complicated and time-consuming. Moreover, when one end of the printing roller is disassembled, the cantilever beam state formed by its own weight is very likely to cause the roller to sink and tilt. At this time, the operator needs to support the printing roller with one hand and use tools with the other hand to disassemble the other end of the printing roller, which is difficult to operate and easy to be distracted during operation, causing the printing roller to bump and damage the printing accuracy. Therefore, a precision single-color double-sided roller printing device is proposed to solve the above problems. Utility Model Content

A movable column is slidably arranged in the inner cavity of the second support block. An insert rod is fixedly arranged on the outer wall of the movable column, and the other end of the printing roller is sleeved on the insert rod. The second support block is also provided with a support unit. When the moving column moves outward to drive the insertion rod to disengage from the printing roller, the support unit is triggered and extends to support the printing roller.

[0007] Preferably, the support unit includes a support column and a support rod. The support column is fixedly installed on the outer wall of the printing roller, and the outer wall of the second support block has an opening through which the support rod extends towards the support column.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] See attached document Figure 1-6 A precision single-color double-sided roller printing device, comprising: Printing machine 1 serves as the basic framework of the entire printing device, providing space and structural support for the installation of other components. A roller shaft 2 is rotatably connected to the printing machine 1 via a rotating shaft. An external power source drives the roller shaft 2 to rotate, conveying the workpiece to be printed on the roller shaft 2 to the printing roller 3 for printing operation. The printing roller 3 is installed in the inner cavity of the printing machine 1, generating relative motion with the surface of the printing material, so that the ink adheres to the surface of the material to form a printed pattern. A first support mechanism and a second support mechanism are respectively provided on opposite sides of the printing machine 1. The first support mechanism includes a first support block 4 slidably connected to one side of the printing press 1. A locking post 401 for locking one end of the printing roller 3 is rotatably connected to the first support block 4. One end of the printing roller 3 is locked onto the locking post 401, which can both ensure that the printing roller 3 can rotate freely and can be axially positioned. When disassembling, the operator pulls the printing roller 3 away from the locking post 401 to disengage the printing roller 3 from the locking post 401, thereby disassembling one end of the printing roller 3. The second support mechanism includes a second support block 5 slidably connected to the other side of the printing press 1. A movable column 501 is slidably arranged in the inner cavity of the second support block 5. An insertion rod 502 is fixedly arranged on the outer wall of the movable column 501. The other end of the printing roller 3 is sleeved on the insertion rod 502 to support the other end of the printing roller 3. When disassembling, the movable column 501 moves into the inner cavity of the second support block 5 to drive the insertion rod 502 to move, so that the insertion rod 502 is disassembled from the printing roller 3, thereby disassembling the other end of the printing roller 3. When the movable column 501 drives the insertion rod 502 to insert into the other end of the printing roller 3, the other end of the printing roller 3 is fixed. The second support block 5 is also provided with a support unit. When the moving column 501 moves outward to drive the insertion rod 502 to disengage from the printing roller 3, the support unit is triggered and extends to support the printing roller 3.

[0020] The support unit includes a support column 301 and a support rod 6. The support column 301 is fixedly installed on the outer wall of the printing roller 3. The outer wall of the second support block 5 has an opening. The support rod 6 extends through the opening toward the support column 301. When the support unit is triggered, the support rod 6 extends and supports the support column 301 to prevent the printing roller 3 from falling when the insertion rod 502 is disengaged. At the same time, it achieves its own extension and retraction actions through cooperation with the insertion rod 502.

[0021] A first toothed block 503 is fixedly installed on the outer wall of the movable column 501. A second gear 703 is rotatably connected to the inner cavity of the second support block 5 via a pin. The first toothed block 503 and the second gear 703 are meshed together. When the movable column 501 moves, the teeth of the first toothed block 503 and the second gear 703 mesh with each other, driving the second gear 703 to rotate around its own axis.

[0022] The inner cavity of the second support block 5 is rotatably connected to the drive shaft 7, and the outer wall of the drive shaft 7 is fixedly provided with the first gear 701. The first gear 701 is meshed with the second gear 703. When the second gear 703 drives the first gear 701 to rotate, the drive shaft 7 rotates accordingly.

[0023] A transmission gear 702 is fixedly installed on the outer wall of the drive shaft 7, and a second tooth block 601 is fixedly installed on the outer wall of the support rod 6. The transmission gear 702 and the second tooth block 601 are meshed together. When the drive shaft 7 rotates, it drives the transmission gear 702 to rotate. The teeth of the transmission gear 702 mesh with the teeth of the second tooth block 601, driving the support rod 6 to move in a straight line, thereby triggering the support unit.

[0024] One end of the drive shaft 7 extends into a second support block 5 and is fixedly connected to a rotating shaft 704. The rotating shaft 704 is hinged to an adjusting rod 705. When the adjusting rod 705 rotates around the rotating shaft 704, it drives the rotating shaft 704 and the drive shaft 7 to rotate together, thereby realizing manual control of the rotation of the drive shaft 7.

[0025] The outer wall of the second support block 5 is fixedly provided with a first locking block 706, and the adjusting rod 705 is locked into the inner wall of the first locking block 706. When the adjusting rod 705 is not required to be operated, it is fixed in a specific position to prevent accidental operation of the device. The outer wall of the second support block 5 is fixedly provided with a second locking block 707, which provides another locking position. The adjusting rod 705 can be locked into different positions according to different operating states to meet different working needs.

[0026] Working principle: In use, the operator holds the adjusting rod 705 and pulls it outward to remove it from the second locking block 707. By rotating the adjusting rod 705, the rotating shaft 704 and the drive shaft 7 rotate together. The rotation of the drive shaft 7 drives the transmission gear 702 on it to rotate. The transmission gear 702 meshes with the second toothed block 601 on the support rod 6, causing the drive support rod 6 to extend forward, so that its end moves to below the support column 301. At this time, the rotation of the drive shaft 7 is transmitted to the meshing second gear 703 through the first gear 701. The rotation of the second gear 703 drives the first toothed block 503, which meshes with it and is fixed on the moving column 501, to move. This moves the moving column 501 and its front end insertion rod 502 smoothly away from the printing roller 3, causing the insertion rod 502 to separate from the end of the printing roller 3. Just before the insertion rod 502 completely disengages... The extended support rod 6 has firmly supported the support column 301 fixed on the cylinder of the printing roller 3, effectively preventing sinking and tilting caused by the weight of the printing roller 3. Then, the adjusting rod 705 is locked into the first locking block 706 to lock the current state. At this time, the operator can safely slide the printing roller 3 to disengage the other end of the printing roller 3 from the locking column 401 for disassembly. During installation, first place one end of the printing roller 3 on the support rod 6. By rotating the printing roller 3, align the other end of the printing roller 3 with the locking column 401. Then push the printing roller 3 towards the locking column 401 to install the other end of the printing roller 3 onto the locking column 401. Then, release the adjusting rod 705 from the first locking block 706 and rotate it in the opposite direction to move the driving column 501 so that the insertion rod 502 is accurately inserted into the end of the printing roller 3. At the same time, the support rod 6 retracts synchronously. Finally, the adjusting rod 705 is locked into the second locking block 707 to complete the fixation.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
