Abstract
Description
Technical Field
[0001] The invention relates to a non-stop feeding system for die-cutting equipment. Background Art
[0002] Die-cutting equipment is a kind of equipment that uses molds to apply pressure to materials for cutting, creasing, hot stamping and other processes. It is widely used in post-processing in industries such as printing and packaging, electronics, and mobile phone rubber pads.
[0003] The original roll-to-roll circular knife die-cutting process or hydrogen energy MEA packaging process adopts roll-to-roll material shaft unwinding. A lot of materials are used. The basic unwinding layout is up and down and on both sides (unwinding material shaft), parallel to the die-cutting knife seat, for compounding and die-cutting of multi-layer materials. When the roll material put into the material shaft is used up, it is necessary to manually stop the equipment and enter the equipment to replace the roll material, and manually tape the head and tail of the new and old roll materials to complete the material replacement action. Because the process and equipment require a large number of roll materials, as long as there is a roll of material to be replaced, it is necessary to stop the machine for manual processing, which greatly affects the utilization rate of the equipment, and manual operations are required (manually handle the head and tail of the new and old materials. Tape sticking) Manual processing of new and old materials (tape splicing) has great differences in experience and processing effects, which will also cause the material to enter the die-cutting knife seat. There will also be a distance of defects (front and back joints of new and old materials, misalignment, wrinkles, etc.), so it will also affect the product yield rate.
[0004] It can be seen that the existing die-cutting equipment has the following problems: 1. The material strip unwinding adopts an up-down layout, and the material cannot be fed from the lateral side of the die-cutting equipment, which is constrained by the space of the production line and poses a safety hazard to the operator. 2. After the material roll is used up, it needs to be stopped and manually replaced, which affects the equipment utilization rate and has high requirements for the operator's experience. After the material is replaced, there will be a distance of defect. Summary of the invention
[0005] The purpose of the present invention is to provide a non-stop feeding system for die-cutting equipment in view of the above problems, break through the space limitation of existing die-cutting equipment when feeding, and realize automatic continuation after the material roll is used up.

[0009] Preferably, the system further comprises a material belt deviation correction device, which is located above the material belt buffer device and is used to correct the deviation of the material belt between the material belt buffer device and the feeding device.

The sliding cutting device on the material receiving device moves longitudinally so that the rolling cutting wheel cooperates with the vertical first edge of the blade to cut the second material belt. The part of the second material belt located on the vertical first side of its fracture is the reserved section. When the rolling cutting wheel cuts the second material belt, the rolling cutting wheel rolls the reserved section of the second material belt to the reserved bonding part of the tape.

In addition, the tape can be pre-placed on the first material receiving guide roller, and the tape connection can be affixed from the other side when the material strip passes by, so that the connection of the material strip is more secure. This method is particularly applicable to the case where the material strip is two layers, so that both layers of the material strip are connected by tape.

With the above structure, each time the cutting work is performed, the rolling cutting wheel first enters the avoidance gap horizontally, then moves out of the avoidance gap longitudinally, and then moves along the vertical first side edge of the blade, thereby enabling the vertical second side end face of the rolling cutting wheel to fit well with the vertical first side edge of the blade, ensuring that the sliding cutting device has a good shearing effect.
[0016] Preferably, the material strip buffer device comprises a buffer bracket, on which a roller group bracket for transverse movement driven by a power device is installed, and each of the buffer bracket and the roller group bracket has a group of material strip support rollers, and the two groups of material strip support rollers are arranged laterally opposite to each other; The two groups of material belt support rollers on the buffer bracket and the roller group bracket are used for staggered winding of the material belt; A front guide roller is installed on the buffer bracket, and a pressure plate capable of moving relative to the front guide roller is installed on the buffer bracket. The pressure plate is connected to a power device that drives it to move. The gap between the pressure plate and the front guide roller is used for the feeding tape to pass through and then move to the tape support roller. After adopting the above structure, since the material connection work will take a certain time, in order to ensure that the material tape can be normally supplied to the die-cutting device during the material connection, the material tape buffer device can cache a part of the material tape in advance. During the material connection work, the buffered material tape can be released to ensure that the material tape is normally supplied to the die-cutting device, thereby realizing continuous material connection without stopping the machine, greatly improving production efficiency. The roller group bracket on the material tape buffer device can move horizontally relative to the buffer bracket to make the two groups of material tape support rollers relatively close or far away. When the two groups of material tape support rollers are relatively far away, the material tape can be cached, and when the two groups of material tape support rollers are relatively close, the material tape can be released. The front guide roller and the pressure plate can cooperate to clamp the material tape from the upstream of the material tape buffer device, ensuring that the material tape splicing device can complete the material connection action, and the material tape buffer device is not affected by the material connection.
[0017] To sum up, the beneficial effects of the present invention are: the non-stop feeding system of the die-cutting equipment realizes feeding from the lateral side of the die-cutting equipment, breaking through the spatial constraints of the prior art that materials can only be fed from the top or front of the die-cutting equipment; workers do not need to enter the die-cutting equipment to replace and connect the material belts as before, and the operation is safer; connecting materials does not need to rely on the experience of workers, avoiding misalignment and wrinkles before and after the joints of new and old materials, and the yield rate is high; there is no need to stop during the material belt connection process, which improves production efficiency.

The material tape buffer device 3 is used to cache the material tape between the material tape connecting device 4 and the feeding device 2 and release the cached material tape when the material tape connecting device 4 connects another material tape.
[0022] After adopting the above structure, a non-stop feeding system for die-cutting equipment is provided, which breaks through the space limitation of the existing die-cutting equipment when feeding, and can realize automatic continuation after the material roll is used up. The non-stop feeding system for die-cutting equipment realizes feeding from the lateral side of the die-cutting equipment 1, breaking through the space constraint of the existing technology that the die-cutting equipment 1 can only be fed from the top or front.
[0023] The feeding device 2 is arranged at the upper or lower part of the die-cutting device 1, and is used to turn the horizontally fed material strip to the vertically fed material strip. The material strip splicing device 4 is arranged at the lateral side of the die-cutting device 1, and the material strip buffer device is located above the material strip splicing device 4. Figure 1In the embodiment shown, the feeding device 2 is arranged on the upper part of the die-cutting device 1. Figure 2 In the embodiment shown, the feeding device 2 is arranged at the lower part of the die-cutting device 1. The material strip is turned from a horizontally flat feeding strip to a vertically flat feeding strip through the feeding device 2, so that the material can be fed from the lateral side of the die-cutting device 1, breaking through the space limitation. During operation, the operator does not need to enter the die-cutting device 1 to replace the material strip, and the operation is safer.
[0024] Reference Figure 1 , Figure 2 The system further includes a material belt deviation correction device 5, which is located above the material belt buffer device and is used to correct the material belt deviation between the material belt buffer device and the feeding device 2.

The steering part 7 is provided with a steering roller 10, one end of the steering roller 10 is close to the feeding side 8 and away from the discharging side 9, and the other end of the steering roller 10 is away from the feeding side 8 and close to the discharging side 9. The steering roller 10 is used to make the material belt entering the feeding side 8 bypass it and turn out from the discharging side 9. When both longitudinal sides of the steering part 7 are the discharging side 9, the steering part 7 is provided with two steering rollers 10, and the two steering rollers 10 are vertically spaced and cross-arranged. The material belt enters horizontally from the feeding side 3 of the feeding device 2, bypasses the steering roller 10 and turns, and then the material belt is longitudinally out from the discharging side 9, thereby realizing the steering transmission of the material belt. When the steering part 7 is provided with two steering rollers 10, it can be realized that two material belts enter from both sides, turn and merge, and then turn out.

The material belt traction device 11 includes an active traction roller 13 and a driven traction roller 14 installed on the frame and arranged vertically at intervals. The frame is provided with a roller driving device 15 for driving the active traction roller 13 to rotate. The material belt traction device 11 is used to pull the material belt into the feeding device 2, and then bypass the steering roller 5 to exit longitudinally.
[0027] Reference Figures 3 to 7In one embodiment of the material strip splicing device 4, the material strip splicing device 4 includes a material strip splicing device frame 16, on which a knife plate 17 is provided, and a material receiving device 18 is provided on each of the lateral sides of the knife plate 17. The material receiving device 18 includes a material receiving bracket 19, on which a material strip pressing device 20, a gluing device 21 and a sliding cutting device 22 driven by a power device and capable of longitudinal movement are provided. The sliding cutting device 22 includes a sliding cutting bracket 23, on which a rolling cutting wheel 24 capable of rotating around a vertical axis is installed, and the vertical second side surface of the rolling cutting wheel 24 is used to cooperate with the edge of the vertical first side of the knife plate 17 to cut the material strip.
[0028] The material tape pressing device 20 on the material receiving device 18 on the first lateral side presses the first material tape against the first lateral side of the knife plate 17, and the sliding cutting device 22 on the material receiving device 18 moves longitudinally so that the rolling cutting wheel 24 on the sliding cutting device 22 cooperates with the vertical first edge of the knife plate 17 to cut off the first material tape, and the portion of the first material tape located on the vertical second side of its fracture is the reserved section, and the gluing device 21 on the material receiving device 18 is used to stick the tape placed in advance thereon to the fracture of the reserved section of the first material tape and make the portion of the tape that exceeds the fracture become the reserved bonding portion.
[0029] The material strip pressing device 20 on the material receiving device 18 located on the second lateral side is used to press the second material strip against the second lateral side of the knife plate 17. The sliding cutting device 22 on the material receiving device 18 moves longitudinally so that the rolling cutting wheel 24 cooperates with the vertical first edge of the knife plate 17 to cut off the second material strip. The portion of the second material strip located on the vertical first side of its fracture is the reserved section. When the rolling cutting wheel 24 cuts off the second material strip, the rolling cutting wheel 24 rolls the reserved section of the second material strip to the reserved bonding portion of the tape.
[0030] Through the coordinated actions of the material tape pressing device 20, the gluing device 21, and the sliding cutting device 22, the working material tape and the spare material tape are cut off, and the retained section of the spare material tape is aligned with the retained section of the working material tape at the fracture, and the two are connected together with the tape. The retained section of the spare material tape continues to be conveyed downstream along with the retained section of the working material tape, thereby realizing automatic splicing of the material tapes, replacing the original manual splicing, and improving production efficiency. Automatic splicing does not need to rely on workers' experience, and there will be no misalignment, wrinkles, etc. before and after the joints of the new and old material tapes, thereby improving the yield rate of the product.
[0031] The tape pressing device 20 in the illustrated embodiment includes a tape pressing plate driven by a cylinder to move laterally; in other embodiments, the tape pressing device 4 may also adopt other structures in the prior art. The gluing device 21 in the illustrated embodiment may include a flip swing arm driven by a cylinder to rotate around a longitudinal axis, and a gluing flip plate for pre-placing the tape is provided at the free end of the flip swing arm. In other embodiments, the gluing device 21 may also adopt other structures in the prior art.
[0032] Reference Figures 4 to 6 The material receiving device 18 is installed on the material strip splicing equipment frame 16 in a way that it can move laterally and is connected to a power device for driving it to move. The material receiving device 18 can move laterally to leave the knife plate 17 for a distance, so that the spare material strip can be inserted from the gap.
[0033] Reference Figure 4 , Figure 5 , two laminating mechanisms 25 are arranged opposite to each other on the material strip splicing equipment frame 16, each laminating mechanism 25 corresponds to a material receiving device 18, and the laminating mechanism 25 is located at the vertical first side of the corresponding material receiving device 18. The laminating mechanism 25 has a first material receiving guide roller 26 driven by a power device to move laterally, and the first material receiving guide rollers 26 on the two laminating mechanisms 25 are arranged opposite to each other. The material receiving device 18 is provided with a second material receiving guide roller 27, and the second material receiving guide roller 27 is located at the vertical second side of the material strip pressing device 20.
[0034] The lateral movement of the laminating mechanism 10 can make the first material receiving guide rollers 26 on the two laminating mechanisms 25 relatively close to each other, and the connection of the material strip with the adhesive tape is squeezed by the two first material receiving guide rollers 26, so that the adhesive tape is more tightly attached. In addition, an adhesive tape can be placed on the first material receiving guide roller 26 in advance, and the adhesive tape can be attached from the other side when the material strip connection passes, so that the connection of the material strip is more secure. This method is particularly applicable to the case where the material strip is two layers, so that both layers of the material strip are connected by the adhesive tape. The second material receiving guide roller 27 can be used in conjunction with the laminating mechanism 25 to provide support for the material strip.
[0035] Reference Figure 6 The vertical first side edge of the blade 17 is provided with an avoidance notch 28, the sliding cutting bracket 23 is provided with a wheel frame 29, the wheel frame 29 is mounted with a wheel axle 30, the rolling cutting wheel 24 is rotatably mounted on the wheel axle 30, and the wheel axle 30 is sleeved with a first spring 31 for applying a force to the rolling cutting wheel 24 toward the vertical second side. When the material receiving device 18 moves horizontally to a position close to the blade 17, the rolling cutting wheel 24 first enters the avoidance notch 28, and when the sliding cutting device 22 slides longitudinally, the rolling cutting wheel 24 overcomes the force of the spring and gradually moves upward to the upper edge of the blade 17, and the sliding cutting device 22 continues to slide longitudinally to make the rolling cutting wheel 24 move longitudinally along the upper edge of the blade 17 to cut the material strip.
[0036] During each cutting operation, the rolling wheel 24 first enters the avoidance gap 28 horizontally, then moves out of the avoidance gap 28 longitudinally, and then the rolling wheel 24 moves along the vertical first side edge of the knife plate 17, thereby enabling the vertical second side end face of the rolling wheel 24 to fit well with the vertical first side edge of the knife plate 17, ensuring that the sliding cutting device 22 has a good shearing effect.
[0037] Reference Figure 4 The material belt buffer device 3 includes a buffer bracket 32, on which a roller bracket 33 is installed, which is driven by a power device to move laterally. The buffer bracket 32 and the roller bracket 33 each have a set of material belt support rollers 34, and the two sets of material belt support rollers 34 are arranged laterally opposite to each other. The two sets of material belt support rollers 34 on the buffer bracket 32 and the roller bracket 33 are used for the material belt to stagger and bypass.
[0038] A front guide roller 35 is installed on the cache bracket 32. A pressure plate 36 that can move relative to the front guide roller 35 is installed on the cache bracket 32. The pressure plate 36 is connected to a power device that drives it to move. The gap between the pressure plate 36 and the front guide roller 35 is used for the feeding belt to pass through and then move to the material belt support roller 34.
[0039] Since the material splicing work will take a certain amount of time, in order to ensure that the material strip can be normally supplied to the die-cutting device 1 during the material splicing, the material strip buffer device 3 can buffer a part of the material strip in advance. During the material splicing work, the buffered material strip can be released to ensure that the material strip is normally supplied to the die-cutting device 1, thereby realizing continuous material splicing without stopping the machine, greatly improving production efficiency. The roller group bracket 33 on the material strip buffer device 3 can move laterally relative to the buffer bracket 32 to make the two groups of material strip support rollers 34 relatively close or far away. When the two groups of material strip support rollers 34 are relatively far away, the material strip can be buffered, and when the two groups of material strip support rollers 34 are relatively close, the material strip can be released. The front guide roller 35 cooperates with the pressure plate 36 to clamp the material strip from the upstream of the material strip buffer device 3, ensuring that the material strip splicing device 4 can complete the material splicing action, and at the same time, the material strip buffer device 3 is not affected by the material splicing.
[0040] The working method of the present invention is as follows: the material belt passes through the material belt connecting device 4, the material belt buffer device 3, and the feeding device 2 in sequence to enter the working part of the die-cutting device 1, wherein the feeding device 2 can be installed on the upper part of the die-cutting device 1, and can also be installed on the lower part of the die-cutting device 1. The feeding device 2 can turn the material belt from a horizontal flat input to a vertical flat output. The vertical flat output is suitable for the longitudinal setting requirements of the working part of the die-cutting device 1. The horizontal flat input allows the material belt to be introduced from the horizontal side of the die-cutting device 1. The material belt connecting device 4 can be arranged on the horizontal side of the die-cutting device 1. When the working material belt is about to be used up, the material belt connecting device 4 can automatically connect to the spare material belt. Before the material belt connecting work of the material belt connecting device 4, the material belt buffer device 3 will cache a part of the working material belt. When the material belt connecting device 4 performs the material belt connecting work, the material belt buffer device 3 releases the cached working material belt without the need to stop in between.
[0041] The non-stop feeding system of the die-cutting equipment realizes feeding from one lateral side of the die-cutting equipment 1, breaking through the spatial constraints of the prior art that the die-cutting equipment 1 can only be fed from the top or front. Workers do not need to enter the die-cutting equipment 1 to replace and connect the material belt as before, and the operation is safer. Connecting materials does not need to rely on the experience of workers, avoiding misalignment and wrinkles before and after the joint of the new and old materials, and the yield rate is high.
