Description

Technical Field

[0001] The present invention relates to a material changing device, specifically to a non-stop material changing system and method for a rotary die-cutting machine, belonging to the technical field of die-cutting. Background Art

[0002] A rotary die-cutting machine, also known as a rotary press or a hobber, is a device used for continuous rotary die-cutting processing. It gets its name from using a solid metal cylindrical die for cutting. The rotary die-cutting machine is one of the devices with the highest production efficiency in die-cutting machines and is widely used in fields such as mobile phones, computers, liquid crystal displays, digital cameras, LCD backlights, etc.

[0003] During the continuous execution of the material tape die-cutting task by the current rotary die-cutting machine, whenever the material tape runs out, manual operation is required to replace the new material tape. Specifically, when the material tape is about to run out or has completely run out, the operator needs to manually stop the machine, and then perform a series of material changing steps: including removing the exhausted material reel, installing a new material roll, re-threading the material tape to the die-cutting station, and performing necessary tension and alignment calibration;

[0004] In the entire material changing process, the equipment is in a completely stopped state. The interval time from stopping to resuming production usually ranges from 10 to 30 minutes depending on the operation proficiency and equipment structure differences. This intermittent stop directly interrupts the continuous production process, resulting in a decrease in production capacity per unit time and a reduction in work efficiency. Therefore, a non-stop material changing system and method for a rotary die-cutting machine are proposed. Summary of the Invention

[0005] In view of this, the present invention provides a non-stop material changing system and method for a rotary die-cutting machine to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0006] The technical solution of the embodiment of the present invention is implemented as follows: A non-stop material changing system for a rotary die-cutting machine includes a die-cutting workbench, on which a material receiving component is installed. The material receiving component includes a support frame, a material receiving cylinder, a vacuum adsorption seat, a transmission motor, two upper mounting plates, a material receiving plate, a driving motor, and two lower mounting plates;

[0007] The vacuum adsorption seat is installed on the opposite surfaces of the two upper mounting plates. Two upper guide rollers are symmetrically installed on the opposite surfaces of the two upper mounting plates. The material receiving cylinder is installed on the upper surface of the support frame. The cylinder shaft of the material receiving cylinder is fixedly connected to the upper surface of the vacuum adsorption seat. A vacuum pump is installed on the upper surface of the support frame. The transmission motor is installed on one side of an upper mounting plate. The material receiving plate is fixedly connected to the opposite surfaces of the two lower mounting plates. Two lower guide rollers are symmetrically installed on the opposite surfaces of the two lower mounting plates. The driving motor is installed on one side of a lower mounting plate.

[0008] Further preferably, the output shaft of the driving motor is fixedly connected to the roller shaft of an upper guide roller, and the two upper guide rollers are connected by a synchronous belt.

[0009] Further preferably, the output shaft of the driving motor is fixedly connected to the roller shaft of a lower guide roller, and the two lower guide rollers are connected by a synchronous belt.

[0010] Further preferably, the position of the vacuum adsorption seat corresponds to that of the material receiving plate. The air inlet of the vacuum pump is communicated with the vacuum adsorption seat through an air pipe. Two guide rods are symmetrically and fixedly connected to the upper surface of the vacuum adsorption seat, and the guide rods are slidably connected to the inside of the support frame.

[0011] Further preferably, bases are fixedly connected to the lower surfaces of the two lower mounting plates. The bases are mounted on the upper surface of the die-cutting workbench, and the support frame is mounted on the upper surface of the bases.

[0012] Further preferably, a first material roller and a spare material roller are mounted outside the die-cutting workbench.

[0013] Further preferably, a die-cutting frame is mounted on the upper surface of the die-cutting workbench, and a circular knife roller and a support roller are mounted inside the die-cutting frame.

[0014] Further preferably, a die-cutting motor is mounted on one side of the die-cutting frame, and the output shaft of the die-cutting motor is fixedly connected to the roller shaft of the circular knife roller.

[0015] The present invention also provides a method for changing materials without stopping the machine for a circular knife die-cutting machine, which is applied to the system, and includes the following steps:

[0016] Step 1: Start the die-cutting motor to drive the circular knife roller. With the cooperation of the support roller, the material tape at this time is the material tape on the first material roller.

[0017] Step 2: When the material tape on the first material roller is about to be used up, pull out the material tape on the spare material roller, start the vacuum pump, adsorb the material tape on the spare material roller through the vacuum adsorption seat, and coat an adhesive on the lower surface of the material tape on the lower surface of the spare material roller.

[0018] Step 3: When the material tape on the current first material roller is separated from the first material roller, push the vacuum adsorption seat to move downward through the receiving cylinder. The vacuum adsorption seat drives the new material tape to move downward to fit with the current material tape. At the same time, the vacuum pump stops working, and the driving motor and the driving motor work simultaneously. At this time, the two material tapes are preliminarily adhered and are respectively in contact with the upper guide roller and the lower guide roller.

[0019] Step 4: Start the upper guide roller and the lower guide roller to feed the two material tapes. During the feeding process, the upper guide roller and the lower guide roller press the two material tapes together to bond and fix them, completing the connection of the two material tapes. Then, the receiving cylinder resets, and the die-cutting mechanism performs die-cutting on the material tapes.

[0020] Step 5: When the material tape on the first material roller is exhausted, remove the first material roller, place it outside the spare material roller and reload the material tape. Finally, achieve the next non-stop material change.

[0021] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:

[0022] In the present invention, the material tape on the spare material roller is adsorbed by the vacuum adsorption seat, and then an adhesive is coated on the lower surface of the material tape on the spare material roller. The receiving cylinder is pushed to move the vacuum adsorption seat downward, and the vacuum adsorption seat drives the new material tape to move downward to fit with the current material tape. The upper guide roller and the lower guide roller feed and press the two material tapes, so that the two material tapes can be bonded and fixed, thereby completing the connection of the two material tapes and realizing non-stop material change. Compared with the prior art, the present invention can realize the connection of the two material tapes by setting the receiving component. When the material tape is about to be exhausted, the new material tape is quickly connected to the old material tape, and during the connection process, the normal die-cutting operation will not be affected, thereby realizing non-stop material change and improving work efficiency.

Detailed implementation manners

[0030] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and the description are considered to be exemplary in nature and not restrictive.

[0031] Embodiment 1

[0032] The embodiments of the present invention will be described in detail below with reference to the drawings.

[0033] As Figures 1 - 4 shown, the embodiment of the present invention provides a non-stop material change system for a circular knife die-cutting machine, including a die-cutting workbench 31, on which a material receiving assembly 101 is installed. The material receiving assembly 101 includes a support frame 11, a material receiving cylinder 13, a vacuum adsorption seat 15, a drive motor 16, two upper mounting plates 17, a material receiving plate 20, a drive motor 21, and two lower mounting plates 22;

[0034] The vacuum adsorption seat 15 is installed on the opposite surfaces of the two upper mounting plates 17. The lower surface of the vacuum adsorption seat 15 is evenly provided with adsorption holes. Two upper guide rollers 18 are symmetrically installed on the opposite surfaces of the two upper mounting plates 17. The material receiving cylinder 13 is installed on the upper surface of the support frame 11. The cylinder shaft of the material receiving cylinder 13 is fixedly connected to the upper surface of the vacuum adsorption seat 15. By pushing the vacuum adsorption seat 15 downward through the material receiving cylinder 13, the vacuum adsorption seat 15 can drive the material tape to move downward;

[0035] A vacuum pump 14 is installed on the upper surface of the support frame 11. The air inlet of the vacuum pump 14 is communicated with the vacuum adsorption seat 15 through a trachea. Then, when the vacuum pump 14 works, the inside of the vacuum adsorption seat 15 is in negative pressure. At this time, the material tape can be adsorbed and fixed by the vacuum adsorption seat 15;

[0036] The drive motor 16 is installed on one side of an upper mounting plate 17. The output shaft of the drive motor 16 is fixedly connected to the roller shaft of an upper guide roller 18. The two upper guide rollers 18 are connected by a synchronous belt. By driving the upper guide roller 18 to rotate through the drive motor 16, under the action of the synchronous belt, the two upper guide rollers 18 rotate synchronously;

[0037] The material receiving plate 20 is fixedly connected to the opposite surfaces of the two lower mounting plates 22. The material tape can be supported by the material receiving plate 20, so that the two material tapes are bonded together.

[0038] Two lower guiding rollers 19 are symmetrically installed on the opposite surfaces of the two lower mounting plates 22. The driving motor 21 is installed on one side of one lower mounting plate 22. The output shaft of the driving motor 21 is fixedly connected to the roller shaft of one lower guiding roller 19. The two lower guiding rollers 19 are connected by a synchronous belt. By driving the rotation of one lower guiding roller 19 by the driving motor 21, under the action of the synchronous belt, the two lower guiding rollers 19 rotate synchronously.

[0039] The position of the vacuum adsorption seat 15 corresponds to that of the material receiving plate 20. When the existing material tape is about to run out, the material change preparation work is started. The vacuum pump 14 is started, and the new material tape is adsorbed by the vacuum adsorption seat 15. Then, an adhesive is coated on the lower surface of the material tape. At this time, the material change preparation is completed. When the current material tape is separated from the material roll, the material change operation is carried out.

[0040] The vacuum adsorption seat 15 is pushed downward by the material receiving cylinder 13. The vacuum adsorption seat 15 drives the new material tape to move downward and fit with the current material tape. At the same time, the vacuum pump 14 stops working, and the transmission motor 16 and the driving motor 21 work simultaneously. At this time, the two material tapes are preliminarily bonded and respectively contact the upper guiding roller 18 and the lower guiding roller 19. The upper guiding roller 18 and the lower guiding roller 19 feed the two material tapes. During the feeding process, the upper guiding roller 18 and the lower guiding roller 19 can also press the two material tapes to fix the two material tapes, thereby completing the connection of the two material tapes. Then, the material receiving cylinder 13 resets, and the die-cutting mechanism die-cuts the material tape.

[0041] In one embodiment, two guiding rods 12 are symmetrically and fixedly connected to the upper surface of the vacuum adsorption seat 15. The guiding rods 12 are slidably connected to the inside of the support frame 11, and the guiding rods 12 can play a guiding role.

[0042] In one embodiment, the lower surfaces of the two lower mounting plates 22 are both fixedly connected with bases 23. The bases 23 are installed on the upper surface of the die-cutting workbench 31, and the support frame 11 is installed on the upper surface of the bases 23. The stability of the material receiving assembly 101 can be enhanced by the bases 23 and the support frame 11.

[0043] In one embodiment, a first material roll 24 and a spare material roll 25 are installed outside the die-cutting workbench 31. Both material rolls are installed on the ground through a support structure and can be moved according to actual usage requirements. For example, when the material tape on the first material roll 24 is used up, the first material roll 24 is taken out and placed outside the spare material roll 25 for the next non-stop material change.

[0044] In one embodiment, a die-cutting table 31 has a die-cutting frame 32 mounted on its upper surface. Inside the die-cutting frame 32, a circular knife roller 33 and a support roller 34 are installed. On one side of the die-cutting frame 32, a die-cutting motor 35 is installed. The output shaft of the die-cutting motor 35 is fixedly connected to the roller shaft of the circular knife roller 33. A tape traction mechanism is also provided on one side of the die-cutting table 31 to enable the tape to move at a constant speed. By driving the circular knife roller 33 with the die-cutting motor 35, the circular knife roller 33, in cooperation with the support roller 34, can perform die-cutting on the tape.

[0045] When the present invention is in operation: The circular knife roller 33 is driven by the die-cutting motor 35. The circular knife roller 33, in cooperation with the support roller 34, can perform die-cutting on the tape. At this time, the tape is the tape on the first material roller 24. When the tape on the first material roller 24 is about to run out, the tape on the spare material roller 25 is pulled out, and then the vacuum pump 14 is started. The tape on the spare material roller 25 is adsorbed through the vacuum adsorption seat 15. Then, an adhesive is coated on the lower surface of the tape on the spare material roller. When the tape on the current first material roller 24 is separated from the first material roller 24, the vacuum adsorption seat 15 is pushed downward by the receiving cylinder 13. The vacuum adsorption seat 15 drives the new tape to move downward and fit with the current tape. At the same time, the vacuum pump 14 stops working, and the transmission motor 16 and the drive motor 21 work simultaneously. At this time, the two tapes are initially bonded and respectively contact the upper guide roller 18 and the lower guide roller 19. The two tapes are fed through the upper guide roller 18 and the lower guide roller 19. During the feeding process, the upper guide roller 18 and the lower guide roller 19 press the two tapes to bond and fix the two tapes, thereby completing the connection of the two tapes. Then, the receiving cylinder 13 resets, and the die-cutting mechanism performs die-cutting on the tape, thus realizing non-stop material change. After the tape on the first material roller 24 runs out, the first material roller 24 is taken out, placed outside the spare material roller 25 and reloaded with tape for the next non-stop material change.

[0046] Compared with the prior art, the present invention can realize the connection of two tapes by setting the receiving component 101. When the tape is about to run out, the new tape is quickly connected to the old tape, and during the connection process, the normal die-cutting operation is not affected, thereby realizing non-stop material change and improving work efficiency.

[0047] Embodiment Two

[0048] The present invention also provides a method for non-stop material change of a circular knife die-cutting machine, which is applied to the above system and includes the following steps:

[0049] Step 1: Start the die-cutting motor 35 to drive the circular knife roller 33. The circular knife roller 33, in cooperation with the support roller 34, and at this time, the tape is the tape on the first material roller 24.

[0050] Step 2: When the material tape on the first material roller 24 is about to be exhausted, pull out the material tape on the spare material roller 25, start the vacuum pump 14, adsorb the material tape on the spare material roller 25 through the vacuum adsorption seat 15, and apply an adhesive to the lower surface of the material tape on the spare material roller;

[0051] Step 3: When the material tape on the current first material roller 24 separates from the first material roller 24, push the vacuum adsorption seat 15 downward through the material receiving cylinder 13. The vacuum adsorption seat 15 drives the new material tape to move downward and fit with the current material tape. At the same time, the vacuum pump 14 stops working, and the transmission motor 16 and the drive motor 21 work simultaneously. At this time, the two material tapes are preliminarily bonded and respectively contact the upper guide roller 18 and the lower guide roller 19;

[0052] Step 4: Start the upper guide roller 18 and the lower guide roller 19 to feed the two material tapes. During the feeding process, the upper guide roller 18 and the lower guide roller 19 press the two material tapes to bond and fix the two material tapes, completing the connection of the two material tapes. Then the material receiving cylinder 13 resets, and the die-cutting mechanism die-cuts the material tape;

[0053] Step 5: After the material tape on the first material roller 24 is exhausted, take out the first material roller 24, place it outside the spare material roller 25 and reload the material tape, and finally achieve non-stop material change for the next time.

[0054] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
