Description

Technical Field

[0001] This utility model belongs to the field of packaging bag printing technology, specifically a tension adaptive adjusting roller structure for packaging bag printing. Background Technology

[0002] The tension adaptive regulating roller used in packaging bag printing is a key device for stabilizing material tension. Its core function is to automatically adjust and compensate for tension fluctuations, ensuring smooth material transport during the printing process and avoiding problems such as wrinkling, stretching, or misregistration.

[0003] Because packaging bags are made of different materials, such as plastic, paper, aluminum foil, or composite materials, the tension adaptive adjustment roller needs to match the friction requirements of different materials. However, many existing tension self-adjusting structures are difficult to disassemble, resulting in the use of only one type of adjustment roller during printing, which is even the case for adjustment rollers.

[0020] 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.

[0021] like Figures 1 to 5 As shown, this utility model provides a tension adaptive adjusting roller structure for packaging bag printing, including a worktable 1. Multiple sliding shafts 2 are fixedly arranged on the inner side of the top of the worktable 1. Sliding blocks 3 are slidably arranged on the outer side of the sliding shafts 2. A locking block 4 is slidably arranged on the top surface of the sliding blocks 3. A fixing block 5 is fixedly arranged on one side of the locking block 4. A lead screw 6 is slidably connected inside the fixing block 5. A turntable 7 is fixedly arranged on the outer side of the lead screw 6. A fiber disc 8 is fixedly arranged on the inner side of the lead screw 6, and the fiber disc 8 is in contact with the sliding block 3. By rotating the turntable 7, the turntable 7 drives the fiber disc 8 to move through the threaded engagement between the lead screw 6 and the fixing block 5. The fiber disc 8 then pushes the sliding block 3 to drive the locking block 4 to move, thereby disassembling the locking block 4 from the top surface of the sliding block 3. The adjusting roller is also disassembled and then replaced. This solves the problem that the tension adjusting roller of the printing press is difficult to disassemble, making it impossible to change different rollers according to different material types. By changing different rollers, it can adapt to different material types, improve work efficiency, and also ensure the printing quality of the packaging bags.

[0022] Specifically, a shaft core 9 is fixedly installed on the inner side of the top of the sliding block 3, and a spring 10 is sleeved on the outer side of the shaft core 9. A retaining ball 11 is fixedly installed on the top surface of the spring 10, and the retaining ball 11 moves inside the sliding block 3. The spring 10 is responsible for pushing the retaining ball 11, while the shaft core 9 is used to increase the stability of the spring 10.

[0023] Furthermore, a limiting plate 301 is fixedly provided on one side of the top surface of the sliding block 3, and the limiting plate 301 is in contact with the card block 4. The limiting plate 301 is used to limit the card block 4 to prevent it from exceeding the range of the sliding block 3 during installation.

[0024] Furthermore, a linear bearing 12 is slidably connected to the outer side of the sliding shaft 2, and the linear bearing 12 is fixedly connected to the sliding block 3. The tension sensor senses the change in tension, and then the tension sensor controls the servo electric slider mechanism to drive the sliding block 3 to slide, thereby adapting to the change in tension.

[0025] It is worth noting that the inner side of the card block 4 is provided with a groove 14, and the card ball 11 is inserted into the groove 14. The card block 4 can be fixed by the card ball 11 to ensure the stability of its top surface adjusting roller.

[0026] It is worth noting that a sliding bracket 13 is provided on the top surface of the card block 4. The sliding bracket 13 includes a connecting shaft 1301 that is fixedly connected to the card block 4. A fixed shaft 1302 is threadedly connected to the top surface of the connecting shaft 1301. The detachable sliding bracket 13 reduces the trouble during maintenance.

[0027] It is worth mentioning that multiple rotating bearings 1303 are fixedly installed on the outer side of the fixed shaft 1302, and a roller 1304 is rotatably connected to the outer side of the rotating bearings 1303. The rotating bearings 1303 can reduce the friction when the roller 1304 rotates.

[0028] The tension sensor and servo electric slider mechanism are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0029] Working principle:

[0030] When using the tension adaptive adjusting roller structure for packaging bag printing, if the tension of the packaging bag outside the sliding frame 13 changes during printing, the internal tension sensor will control the servo electric slider mechanism to drive the sliding block 3 to move outside the sliding shaft 2 on the top surface of the worktable 1 to adapt to the tension change. The sliding block 3 moves through the linear bearing 12 to facilitate sliding. When encountering different materials, it is necessary to match the corresponding friction requirements. In this case, the sliding frame 13 needs to be replaced. The turntable 7 is rotated, and the turntable 7 drives the fiber disc through the threaded engagement of the lead screw 6 and the fixed block 5. 8 moves, and the fiber disc 8 drives the locking block 4 to move by pushing the sliding block 3. The fiber disc 8 then removes the locking block 4 from the top surface of the sliding block 3 and replaces it. The same method is used when installing the locking block 4 until the locking block 4 is in contact with the limiting plate 301. At the same time, the locking ball 11 is popped out by the spring 10 on the outside of the shaft core 9 and engages with the groove 14 on the bottom surface of the locking block 4. The roller 1304 in the sliding frame 13 rotates on the outside of the fixed shaft 1302 through the rotating bearing 1303, thereby playing the role of conveying the conveyor belt and reducing friction. The connecting shaft 1301 is connected to the locking block 4.
