Description

Technical Field

[0001] This invention belongs to the technical field of winding equipment for roll-to-roll hot stamping machines, and particularly relates to a winding machine for roll-to-roll hot stamping machines. Background Technology

[0002] Roll-to-roll hot stamping machines are commonly used equipment in the printing and packaging industry. Their winding mechanism is used to roll the hot-stamped paper into a tube shape. Currently, when changing products using roll-to-roll hot stamping machines, the following method is used: first, the entire roll of paper is lifted by a cylinder, then the raised crossbeam is manually rolled outwards, and then the cylinder is lowered. After the entire roll of paper has rolled to the outside, the air shaft is manually pulled out.

[0003] However, the above-mentioned existing technical solutions have obvious drawbacks: First, the manual operation process is cumbersome, time-consuming and labor-intensive, and the work efficiency is low; second, the manual rolling and pulling of the shaft has poor operation stability and is prone to paper roll deviation and damage; third, during the operation, the personnel need to be in close contact with the moving parts, which is not safe enough and poses a safety risk. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a roll-to-roll hot stamping machine rewinding machine, which has the advantages of automated rewinding and changing, safe and efficient operation, and stable paper roll transfer. It solves the problems of time-consuming and labor-intensive manual rewinding, easy damage to paper rolls, and low operational safety in the prior art.

[0005] This invention is implemented as follows: a roll-to-roll hot stamping rewinding machine includes a take-up shaft assembly, a take-up shaft moving mechanism, a lifting mechanism, a flipping mechanism, and a sensor assembly. The take-up shaft assembly includes a first guide roller, a second guide roller, an air sleeve, and a shaft. The air sleeve is fitted onto the shaft for mounting the paper core. The take-up shaft moving mechanism includes a linear guide rail and a first servo reducer. The take-up shaft assembly is mounted on the linear guide rail. The first servo reducer drives the shaft to extend and retract. The lifting mechanism includes a front lift, a rear lift, and a second servo motor. The front and rear lifts are respectively located on the front and rear sides of the take-up shaft assembly. The second servo motor drives the front and rear lifts to lift independently. The flipping mechanism includes a flipping body connected to the rear lift. When the rear lift lifts, it causes the flipping body to tilt.

[0006] As a preferred embodiment of the present invention, the paper take-up shaft assembly further includes a pressure roller, which is used to press the paper to prevent it from shrinking back during paper changing. During paper take-up, the paper is introduced into the second roller after passing through the first roller. During paper changing, the pressure roller presses the paper to prevent it from shrinking back.

[0007] This setting ensures that the paper remains taut during the paper changing process, preventing the paper roll from becoming loose or misaligned due to paper shrinkage, thus guaranteeing the smooth progress of subsequent unwinding operations.

[0008] As a preferred embodiment of the present invention, the paper take-up shaft moving mechanism further includes a winding power component, which is a third servo reducer. The third servo reducer is used to drive the shaft to rotate in order to achieve the winding action.

[0009] This setting allows for precise control of the shaft rotation speed, ensuring uniform tension of the paper roll during winding and improving the quality stability of the finished paper roll.

[0010] As a preferred embodiment of the present invention, the flipping mechanism is also equipped with a shovel plate, which can guide the paper roll onto the shovel plate when the flipping body is tilted.

[0011] With this setup, the roll paper can slide smoothly into the shovel plate along the inclined surface of the flip plate body, avoiding damage caused by manual handling of the roll paper. At the same time, the shovel plate, together with the small hydraulic trolley, can quickly complete the roll paper transfer, improving the efficiency of the roll changing operation.

[0012] As a preferred embodiment of the present invention, the sensor assembly includes a photoelectric sensor, a limit switch, and a proximity switch.

[0013] With this setup, photoelectric sensors are used to detect the position of the roll paper, limit switches are used to limit the extension and retraction of the shaft, proximity switches are used to limit the lifting position of the elevator, and the take-up shaft moving mechanism, lifting mechanism, and sensor assembly are all electrically connected to the control system in the roll-to-roll hot stamping machine to control each mechanism to perform unloading and installation actions.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: High degree of automation: By replacing manual operation with "one-click unloading + one-click installation", the labor input cost is effectively reduced and the operation efficiency is greatly improved; High safety performance: effectively avoids close contact between workers and operating parts, eliminating safety hazards caused by manual operation; High operational stability: Precise control is achieved through servo drive and sensor limit, eliminating the risk of deviation and damage during paper roll replacement, effectively improving work quality; Easy and flexible to operate: It effectively simplifies the operation process, lowers the skill threshold for operators, and is widely applicable.

[0017] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0018] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0019] refer to Figures 1 to 2 As shown in the figure, an embodiment of the present invention provides a roll-to-roll hot stamping machine winding machine, including a take-up shaft assembly, a take-up shaft moving mechanism, a lifting mechanism, a flipping mechanism, and a sensor assembly. The take-up shaft assembly includes a first roller 1, a second roller 2, an air sleeve 4, and a shaft 5. The air sleeve 4 is sleeved on the shaft 5 and is used to mount the paper core. The take-up shaft moving mechanism includes a linear guide rail 8 and a first servo reducer 7. The take-up shaft assembly is mounted on the linear guide rail 8. The first servo reducer 7 drives the shaft 5 to extend and retract. The lifting mechanism includes a front lift 10, a rear lift 12, and a second servo motor 9. The front lift 10 and the rear lift 12 are respectively arranged on the front and rear sides of the take-up shaft assembly. The second servo motor 9 drives the front lift 10 and the rear lift 12 to lift independently. The flipping mechanism includes a flipping body 15, which is connected to the rear lift 12. When the rear lift 12 lifts, it causes the flipping body 15 to tilt.

[0020] Specifically, the paper take-up shaft assembly also includes a pressure roller 3, which is used to press the paper to prevent it from shrinking back when changing paper. When taking the paper, the paper is introduced into the second roller 2 through the first roller 1. When changing paper, the pressure roller 3 presses the paper to prevent it from shrinking back.

[0021] By adopting the above solution, the paper can remain taut during the paper changing process, avoiding loosening and misalignment of the roll caused by paper shrinkage, and ensuring the smooth progress of subsequent unwinding operations.

[0022] Specifically, the paper take-up shaft moving mechanism also includes a winding power component, which is a third servo reducer 6. The third servo reducer 6 is used to drive the shaft 5 to rotate in order to achieve the winding action.

[0023] By adopting the above solution, the rotation speed of shaft 5 can be precisely controlled, ensuring uniform tension of the paper roll during the winding process and improving the quality stability of the finished paper roll.

[0024] Specifically, the flipping mechanism is also equipped with a shovel plate 13, which can guide the paper roll onto the shovel plate 13 when the flipping body 15 is tilted.

[0025] Using the above solution, the roll paper can be smoothly slid into the shovel plate 13 along the inclined surface of the flip plate body 15, avoiding damage caused by manual handling of the roll paper. At the same time, the shovel plate 13, together with the small hydraulic trolley, can quickly complete the roll paper transfer, improving the efficiency of the roll changing operation.

[0026] Specifically, the sensor assembly includes a photoelectric sensor, a limit switch, and a proximity switch.

[0027] Using the above scheme, the photoelectric sensor is used to detect the position of the roll paper, the limit switch is used to limit the extension and retraction stroke of the shaft 5, the proximity switch is used to limit the lifting position of the elevator, and the take-up shaft moving mechanism, the lifting mechanism and the sensor assembly are all electrically connected to the control system in the roll-to-roll hot stamping machine to control each mechanism to perform unloading and installation actions.

[0028] Working principle of the invention: During use, in the winding stage: the third servo reducer 6 drives the shaft 5 to rotate, the paper is guided by roller 1, then introduced into roller 2, and wound onto the paper core of the air-expanding sleeve 4. At this time, the pressure roller 3 remains in a raised state and does not contact the paper, continuing to wind it onto the paper core.

[0029] Unwinding Stage: After winding is completed, press the one-button unwinding button. The control system in the roll-to-roll hot stamping machine automatically executes the following actions according to the program: Lifting drive: The second servo motor 9 drives the front lift 10 and the rear lift 12 to rise synchronously until the photoelectric sensor detects the roll paper, at which point the front lift 10 and the rear lift 12 stop moving; Unwinding and core pulling: The program controls the air shaft corresponding to the air sleeve 4 to automatically release air, so that the roll core is released from the air sleeve 4. Then, the first servo reducer 7 drives the shaft 5 to extend and retract, pulling the roll core shaft completely out; Guided transfer: The front lift 10 and the rear lift 12 descend synchronously until the limit switch is triggered and they stop. Then, only the rear lift 12 is driven to rise alone, driving the flip plate body 15 to rise synchronously, so that the roll paper rolls along the inclined surface of the flip plate body 15 into the shovel plate 13. Finally, the roll paper on the shovel plate 13 is transferred out of the site by a small hydraulic trolley. No manual intervention is required throughout the process.

[0030] Installation phase: After the new roll paper core is fitted into the air expansion sleeve 4, press the button, and the first servo reducer 7 drives the shaft 5 to automatically push it to the designated installation position. Then the program controls the air expansion shaft to automatically inflate, so that the air expansion sleeve 4 tightens the paper core, completing the fixing of the new roll, and the equipment can resume winding production.
