Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to a die-cutting machine deviation correction and cutting mechanism and a die-cutting machine. Background Art

[0002] Die-cutting machine is also called die-cutting machine, cutting machine, CNC punching machine, which is mainly used for die-cutting (full cutting, half cutting), creasing and hot stamping operations, laminating, and automatic waste discharge of corresponding non-metallic materials, self-adhesive stickers, EVA, double-sided tape, electronics, mobile phone pads, etc. The die-cutting machine uses steel knives, hardware molds, steel wires (or templates carved from steel plates) to apply a certain amount of pressure through the stamping plate to cut printed products or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding.

[0003] Patent publication number CN214610632U discloses a self-adhesive die-cutter with an automatic deflection correction mechanism. This application uses a laser sensor to detect whether the self-adhesive label is deflected, then uses a transverse movement mechanism to slightly shift the label to correct the deflection. However, this die-cutter is unable to process parts whose edges fall outside the detection range. Consequently, parts with partially out-of-specification dimensions cannot be properly corrected, impacting processing quality. Utility Model Content

[0004] The purpose of the present utility model is to overcome the defects of the above-mentioned prior art and to provide a die-cutting machine correction and cutting mechanism and a die-cutting machine, which can not only correct the material strip that exceeds the set position, but also process the material strip that exceeds the set size and cut off the excess part, which can effectively prevent the material from getting stuck and affecting the processing quality.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] In one aspect, the present invention provides a die-cutting machine deflection correction and cutting mechanism for adjusting a material strip to a set size and a set position during transmission. The deflection correction and cutting mechanism comprises:

[0007] Mounting rack;

[0008] Two sets of detection components mounted on the mounting frame and used to detect whether the material strip is offset or exceeds the size standard, the two sets of detection components and the set positions set on both sides of the material strip are located on the same vertical line;

[0009] Correction plates located on both sides of the material belt and capable of pushing the material belt, the correction plates being configured to push the material belt to the set position when the detection component on one side of the material belt fails to detect the material belt, corresponding to a portion of the material belt exceeding a set position;

[0010] And a cutting knife with a blade facing upward located on both sides of the material strip, the cutting knife is configured to move to the set position of the material strip and cut off the part exceeding the set size when the detection components on both sides of the material strip cannot detect the material strip, corresponding to the presence of a part of the material strip that exceeds the set size.

[0011] Furthermore, the detection component includes:

[0012] Two infrared emitters located below both sides of the material strip and used to emit infrared rays to the material strip, with the spacing between the infrared emitters being adjustable;

[0013] and two infrared receivers located above both sides of the material strip and used for receiving the infrared rays emitted by the infrared emitter, wherein the distance between the infrared receivers is adjustable.

[0014] Furthermore, the mounting frame is a frame-shaped frame, the infrared transmitter is located on the upper surface of the bottom end of the mounting frame, and the infrared receiver is located on the lower surface of the top end of the mounting frame.

[0015] Furthermore, the spacing between the infrared emitters and the spacing between the infrared receivers are adjustable, as can be achieved by those skilled in the art based on existing technology. To further enhance this effect, a first chute is provided on the upper surface of the bottom end of the mounting frame, to which two first sliders are slidably connected, and the infrared emitters are mounted on the first sliders; a second chute is provided on the lower surface of the top end of the mounting frame, to which two second sliders are slidably connected, and the infrared receivers are mounted on the second sliders. The distance between the two infrared emitters is adjusted by moving the distance between the two first sliders, and the distance between the two infrared receivers is adjusted by moving the distance between the two second sliders. This ensures that the infrared emitters and infrared receivers remain on the same vertical line during movement, and that this vertical line is unobstructed. This vertical line corresponds to the set position of the material strip to accommodate the needs of material strips of different sizes.

[0016] Furthermore, scale lines are provided on the side of the first sliding groove.

[0017] Furthermore, when the first slider moves to a set position, the first slider is fixed to the first sliding groove by a fastener.

[0018] Furthermore, the first sliding block is a collar, and the fastener is a fixing bolt.

[0019] Furthermore, the lowest point of the deflection-correcting plate is lower than the height of the material strip, and the highest point of the deflection-correcting plate is higher than the height of the material strip.

[0020] Furthermore, the deflection-correcting plate is connected to a first pushing member mounted on the mounting frame, pushing the deflection-correcting plate to move toward or away from the material strip along the width direction of the material strip.

[0021] Furthermore, the first pushing member is a common structure in this field. In order to further enhance its pushing effect and make it push more stably, the first pushing member is a push rod, which is installed on the mounting frame. The telescopic end of the push rod is connected to the correcting plate to push the correcting plate to move.

[0022] Furthermore, there are two correcting plates and two first pushing members, which are respectively arranged on both sides of the material belt. A first feed fixing rod is arranged below the material belt through the two correcting plates. The first feed fixing rod is arranged along the width direction of the material belt, and the first pushing member pushes the correcting plate to move along the first feed fixing rod.

[0023] Furthermore, the surface of the cutting edge of the resection knife is higher than the surface of the material strip, and the height above the cutting edge is no more than 0.2 mm, preferably no more than 0.1 mm.

[0024] If the detection components on both sides of the strip fail to detect the strip, indicating that the strip exceeds the set size, the cutting blade moves along the width of the strip, toward the strip, and below the strip. At this point, the cutting blade remains stationary while the strip advances, with the blade's edge passing through the strip. The relative motion between the cutting blade and the strip causes the cutting blade to remove the portion of the strip that exceeds the set size.

[0025] Furthermore, the cutting knife is connected to a second pushing member installed on the mounting frame, pushing the cutting knife to move in a direction close to or away from the material strip.

[0026] Furthermore, the second pushing member is a common structure in this field. In order to further enhance its pushing effect and make it push more stably, the second pushing member is a push rod, which is installed on the mounting frame. The telescopic end of the push rod is connected to the resection knife to push the resection knife to move.

[0027] Furthermore, there are two cutting knives and two second pushing members, which are respectively arranged on both sides of the material belt. A second feed fixing rod is provided below the material belt and passes through the two cutting knives. The second feed fixing rod is arranged along the width direction of the material belt, and the second pushing member pushes the cutting knife to move along the second feed fixing rod.

[0028] Furthermore, the deflection-correcting plate and the cutting knife are arranged on both sides of the material strip, one in front and one behind, along the traveling direction of the material strip, and the deflection-correcting plate and the cutting knife do not interfere with each other during operation.

[0029] On the other hand, the present invention further provides a die-cutting machine, which includes the die-cutting machine deviation correction and cutting mechanism described above, and further includes:

[0030] A feeding mechanism located before the deviation-correcting and cutting mechanism and used for guiding the material strip to be fed into the die-cutting machine;

[0031] a die-cutting mechanism located after the deflection-correcting and cutting mechanism and used for die-cutting the material strip;

[0032] and a material pulling mechanism located behind the die-cutting mechanism and used for controlling the advancement of the material strip.

[0033] Furthermore, the feeding mechanism, die-cutting mechanism, and pulling mechanism are common mechanical structures in this field. In order to keep the material strip in a taut state during the movement process, thereby preventing the correction plate from pushing the material strip or the cutting knife from cutting off parts of the material strip that exceed the set size, errors are generated, the feeding mechanism, die-cutting mechanism, and pulling mechanism are set to the following structures.

[0034] Further preferably, the feeding mechanism includes:

[0035] Feeding pallet,

[0036] And a pressing assembly for pressing the material strip and making it close to the surface of the feeding carriage, including a rotating motor installed on one side of the feeding carriage, a rotating shaft connected to and rotating with the output end of the rotating motor, and a pressing plate arranged on the rotating shaft and rotating with the rotating shaft to press the material strip.

[0042] The material strip is in contact with the rolling surface of the drawing roller, and one end of the material strip passes through the gap between the drawing roller and the pressing roller and enters the winding device for winding.

[0043] Further preferably, the die-cutting mechanism includes an upper die base and a lower die base, and the upper die base is provided with a die-cutting knife for die-cutting the material strip.

[0044] Furthermore, when the material strip is composed of a multi-layer structure, a laminating mechanism for laminating the multi-layer structure of the material strip is further provided between the deviation correction and cutting mechanism and the die-cutting mechanism. The laminating mechanism adopts a conventional laminating machine in the die-cutting field, such as a roll laminating machine.

[0045] Furthermore, the laminating mechanism and the die-cutting mechanism can be provided in plurality according to actual process conditions, and the structures of the plurality of laminating mechanisms can be the same or different, and the structures of the plurality of die-cutting mechanisms can be the same or different.

[0046] Furthermore, the die-cutting machine also includes a main frame, and the deviation-correcting and cutting mechanism, feeding mechanism, die-cutting mechanism, and pulling mechanism are all installed on the main frame.

[0047] Furthermore, the die-cutting machine also includes a control system that is connected to the deviation-correcting and cutting mechanism, the feeding mechanism, the die-cutting mechanism, and the pulling mechanism and controls the operation of the control unit.

[0048] Furthermore, the control system is connected to the laminating mechanism and controls its operation.

[0049] Furthermore, the control system adopts PLC control.

[0050] Compared with the prior art, the utility model has the following advantages:

[0051] (1) When the deflection correction and cutting mechanism of the present invention is in use, the working operation of different mechanisms is realized through the detection conditions of the detection components. When both sets of detection components cannot detect the material strip, the material strip has a portion that exceeds the set size, and the cutting knife moves to the set position of the material strip and cuts off the portion that exceeds the set size; when the detection component on one side of the material strip cannot detect the material strip, the corresponding material strip has a portion that exceeds the set position, and the deflection correction plate pushes the material strip to the set position; when the detection components at both ends of the material strip can all detect the material strip, the material strip advances to the next workstation, and the deflection correction plate and the cutting knife do not work. The structural principle is simple, which is conducive to the effective operation of the deflection correction and cutting mechanism, and will not cause a state of shutdown due to a certain program being too complicated, and can effectively avoid the occurrence of material jamming.

[0052] (2) When the deviation correction and cutting mechanism of the present invention is used, the infrared transmitter cooperates with the infrared receiver to detect the deviation of the material, which has low cost and high detection accuracy. The first pusher is used to push the straightening plate to correct the deviation, and the second pusher is provided to push the cutting knife to move, so that the cutting knife can cut the part that exceeds the set size to prevent the material from getting stuck.

[0053] (3) The die-cutting machine of the present invention can calibrate the position and size of the material strip before die-cutting by setting a correction and cutting mechanism, so that the position of subsequent die-cutting is more accurate, which can effectively improve the product qualification rate and reduce production time and production costs.

[0078] As one preferred embodiment, the spacing between the infrared emitters 221 and the spacing between the infrared receivers 222 are adjustable, as can be achieved by those skilled in the art based on existing techniques. To further enhance this effect, a first slot 211 is provided on the upper surface of the bottom end of the mounting frame 21.

[0122] and two infrared receivers 222 located above both sides of the material strip 1 and used to receive the infrared rays emitted by the infrared transmitter 221 , wherein the distance between the infrared receivers 222 is adjustable.

[0123] In this embodiment, the mounting frame 21 is a frame-shaped frame, the infrared transmitter 221 is located on the upper surface of the bottom end of the mounting frame 21 , and the infrared receiver 222 is located on the lower surface of the top end of the mounting frame 21 .

[0124] In this embodiment, if Figure 1 and 3 As shown, the spacing between the infrared emitters 221 and the spacing between the infrared receivers 222 are adjustable, as can be achieved by those skilled in the art based on existing techniques. To further enhance this effect, a first slot 211 is provided on the upper surface of the bottom end of the mounting frame 21. Two first sliders 212 are slidably connected to the first slot 211, with the infrared emitters 221 mounted on the first sliders 212. A second slot 213 is provided on the lower surface of the top end of the mounting frame 21. Two second sliders 214 are slidably connected to the second slot 213, with the infrared receivers 222 mounted on the second sliders 214. The distance between the two infrared emitters 221 is adjusted by moving the distance between the two first sliders 212, and the distance between the two second sliders 214 is adjusted by moving the distance between the two infrared receivers 222. This ensures that the infrared emitters 221 and infrared receivers 222 remain on the same vertical line during movement, with no obstructions along this vertical line. This vertical line corresponds to the set position of the material strip 1 to accommodate different sizes of material strips 1.

[0125] In this embodiment, a scale line 2111 is provided on the side of the first chute 211. When the first slider 212 moves to a set position, the first slider 212 is fixed to the first chute 211 by a fastener 215. The first slider 212 is a collar, and the fastener 215 is a fixing bolt.

[0126] In this embodiment, the lowest point of the deflection-correcting plate 23 is lower than the height of the material strip 1 , and the highest point of the deflection-correcting plate 23 is higher than the height of the material strip 1 .

[0127] In this embodiment, the deflection-correcting plate 23 is connected to a first pushing member 25 mounted on the mounting frame 21 , pushing the deflection-correcting plate 23 to move toward or away from the material strip 1 along the width direction of the material strip 1 .

[0128] In this embodiment, the first pushing member 25 is a common structure in this field. In order to further enhance its pushing effect and make it push more stably, the first pushing member 25 is a push rod, which is installed on the mounting frame 21. The telescopic end of the push rod is connected to the correcting plate 23 to push the correcting plate 23 to move.

[0129] In this embodiment, there are two correcting plates 23 and two first pushing members 25, which are respectively arranged on both sides of the material belt 1. A first feed fixing rod 27 is arranged below the material belt 1 through the two correcting plates 23. The first feed fixing rod 27 is arranged along the width direction of the material belt 1, and the first pushing member 25 pushes the correcting plate 23 to move along the first feed fixing rod 27.

[0130] In this embodiment, the surface where the cutting edge of the cutting knife 24 is located is higher than the surface of the material strip 1, and the height above the cutting edge does not exceed 0.2 mm, preferably does not exceed 0.1 mm, and in this embodiment exceeds 0.1 mm.

[0131] When the detection components 22 on both sides of the material strip 1 cannot detect the material strip 1, it indicates that there is a portion of the material strip 1 that exceeds the set size. The cutting knife 24 moves along the width direction of the material strip 1 toward the bottom of the material strip 1. At this time, the cutting knife 24 remains stationary while the material strip 1 moves forward. The cutting edge of the cutting knife 24 passes through the material strip 1. The relative movement of the cutting knife 24 and the material strip 1 causes the cutting knife 24 to cut off the portion of the material strip 1 that exceeds the set size.

[0132] In this embodiment, the cutting knife 24 is connected to a second pushing member 26 installed on the mounting frame 21 , pushing the cutting knife 24 to move in a direction close to or away from the material strip 1 .

[0133] In this embodiment, the second pushing member 26 is a common structure in this field. In order to further enhance its pushing effect and make it push more stably, the second pushing member 26 is a push rod, which is installed on the mounting frame 21. The telescopic end of the push rod is connected to the cutting knife 24 to push the cutting knife 24 to move.

[0134] In this embodiment, two cutting knives 24 are provided, and two second pushing members 26 are provided, which are respectively arranged on both sides of the material strip 1. A second feed fixing rod 28 is provided below the material strip 1 through the two cutting knives 24. The second feed fixing rod 28 is arranged along the width direction of the material strip 1, and the second pushing member 26 pushes the cutting knife 24 to move along the second feed fixing rod 28.

[0135] In this embodiment, the deflection-correcting plate 23 and the cutting knife 24 are arranged on both sides of the material strip 1 in a front-and-rear manner along the traveling direction of the material strip 1 , and the deflection-correcting plate 23 and the cutting knife 24 do not interfere with each other during operation.

[0136] The working process and working principle of the deviation correction and removal mechanism 2 are as follows:

[0137] Adjust the positions and spacing of the two infrared emitters 221 so that the two infrared emitters 221 are respectively located directly below the set positions A and B of the material strip 1; adjust the positions and spacing of the two infrared receivers 222 so that the two infrared receivers 222 are respectively located directly above the set positions A and B of the material strip 1; make one infrared emitter 221, point A, and one infrared receiver 222 on the same vertical line; make one infrared emitter 221, point B, and one infrared receiver 222 on the same vertical line.

[0138] The material strip 1 passes through the deflection correction and cutting mechanism 2. When the infrared rays emitted by the infrared emitters 221 of one group of the detection components 22 cannot be received by the infrared receiver 222, it means that one side of the material strip 1 exceeds the line where the set position point A or point B is located, that is, the position of the material strip 1 is offset, but the size does not exceed the set size. At this time, the deflection correction plate 23 starts to work. The first pushing member 25 pushes the deflection correction plate 23 to move along the first feed fixing rod 27, and pushes the material strip 1 to the line where the set position point A or point B is located, and makes its edge coincide with the line where point A or point B is located, and then the deflection correction plate 23 stops. When the infrared emitters 221 on both sides of the material strip 1 are blocked at the same time or are not blocked, the deflection correction plate 23 returns to its original position and does not work. Since the lowest point of the correcting plate 23 is lower than the height of the material strip 1 and the highest point of the correcting plate 23 is higher than the height of the material strip 1 , when the correcting plate 23 contacts the material strip 1 , the correcting plate 23 can push the material strip 1 .

[0139] When the infrared rays emitted by the infrared emitters 221 of both detection assemblies are simultaneously unable to be received by the infrared receivers 222, it indicates that both sides of the material strip 1 have exceeded the set size, and the portion of the material strip 1 that exceeds the set size is the portion that exceeds the set size. At this point, the cutting blades 24 begin operation. The second pusher 26 propels the cutting blades 24 along the second feed fixing rod 28, pushing them to the set position lines A and B, respectively, positioning them below the material strip 1 with their blades facing upward. Because the surface of the cutting blades 24 is 0.1 mm above the surface of the material strip 1, relative motion occurs between the material strip 1 and the cutting blades 24 as the material strip 1 advances, allowing the cutting blades 24 to remove the portion of the material strip 1 that exceeds the set size. This portion of the material strip 1 that exceeds the set size does not limit the movement of the cutting blades 24, causing them to become stuck. Furthermore, the portion of the strip 1 removed by the cutter 24 that exceeds the set size is typically less than 1 mm. Therefore, the effect of the portion exceeding the set size on the cutter 24 is further reduced, and no limiting effect occurs. The cutter 24 can smoothly move to the set position line at point A and point B. When the infrared emitters 221 at both ends of the strip are not simultaneously blocked, the cutter 24 returns to its original position and does not operate.

[0140] When the infrared emitters 221 at both ends of the material strip 1 are not shielded, the deflection-correcting plate 23 and the cutting knife 24 do not work, and the material strip 1 moves normally.

[0141] Example 2

[0142] A die-cutting machine, such as Figure 4 As shown, it includes the die-cutting machine correction and cutting mechanism described in Example 1, and also includes:

[0143] A feeding mechanism 3 located before the deviation-correcting and cutting mechanism 2 and used for guiding the material strip 1 into the die-cutting machine;

[0144] A die-cutting mechanism 4 located behind the deflection-correcting and cutting mechanism 2 and used for die-cutting the material strip 1;

[0145] And a material pulling mechanism 5 is located behind the die-cutting mechanism 4 and is used to control the movement of the material strip 1.

[0146] In this embodiment, the feeding mechanism 3, the die-cutting mechanism 4, and the pulling mechanism 5 are common mechanical structures in this field. In order to keep the material strip 1 in a taut state during the movement process, thereby preventing the correction plate 23 from pushing the material strip 1 or the cutting knife 24 from causing errors in the process of cutting off the parts of the material strip 1 that exceed the set size, the feeding mechanism 3, the die-cutting mechanism 4, and the pulling mechanism 5 are set to the following structure.

[0147] In this embodiment, the feeding mechanism 3 includes:

[0148] Feeding carriage 31,

[0149] And a pressing assembly 32 for pressing the material strip 1 and making it close to the surface of the feeding carriage 31, including a rotating motor 321 installed on one side of the feeding carriage 31, a rotating shaft 322 connected to and rotating with the output end of the rotating motor 321, and a pressing plate 323 arranged on the rotating shaft 322 and rotating with it to press the material strip 1.

[0150] In this embodiment, the material pulling mechanism 5 includes:

[0151] Drive device;

[0152] a drawing roller 51 connected to the driving device and driven to rotate thereby;

[0153] A pressing roller 52 is provided above the drawing roller 51;

[0154] and a winding device located behind the drawing roller 51 and the pressing roller 53 for winding the material strip 1;

[0155] The material strip 1 abuts against the rolling surface of the drawing roller 51 , and one end of the material strip 5 passes through the gap between the drawing roller 51 and the pressing roller 52 and enters the winding device for winding.

[0156] In this embodiment, the die-cutting mechanism 4 includes an upper die base 41 and a lower die base 42 , and a die-cutting knife for die-cutting the material strip is provided on the upper die base 41 .

[0157] In this embodiment, when the material strip 1 is composed of a multi-layer structure, a laminating mechanism 6 for laminating the multi-layer structure of the material strip is further provided between the deflection correction and cutting mechanism 2 and the die-cutting mechanism 4. The laminating mechanism 6 adopts a conventional laminating machine in the die-cutting field, such as a roll laminating machine.

[0158] In this embodiment, the laminating mechanism 6 and the die-cutting mechanism 4 can be provided in plurality according to actual process conditions. The structures of the laminating mechanisms 6 and the die-cutting mechanisms 4 can be the same or different.

[0159] In this embodiment, the die-cutting machine further includes a main frame 7 , and the deviation-correcting and cutting mechanism 2 , the feeding mechanism 3 , the die-cutting mechanism 4 , and the pulling mechanism 5 are all mounted on the main frame 7 .

[0160] The working process and working principle of the die-cutting machine are as follows:

[0161] The material strip 1 enters the feed mechanism 3 and is guided therein. The material strip 1 is pressed against the surface of the feed carriage 31 and is pressed by the pressing assembly 32. After being fed in, the material strip passes through the deflection-correcting and cutting mechanism 2, the laminating mechanism 6, the die-cutting mechanism 4, and the pulling mechanism 5 in sequence. The pulling mechanism 5 provides the moving force for the material strip 1, pulling it forward. At this point, the material strip 1 that has passed through the deflection-correcting and cutting mechanism 2, the laminating mechanism 6, the die-cutting mechanism 4, and the pulling mechanism 5 is test waste. When the material strip 1 starts to have pulling force, the die-cutting machine officially begins to operate, and the material strip 1 becomes a useful working material strip.

[0162] At this time, the material belt 1 enters from the feeding mechanism 3, and the positions and spacing of the two infrared emitters 221 are adjusted so that the two infrared emitters 221 are respectively located directly below the set positions A and B of the material belt 1, and the positions and spacing of the two infrared receivers 222 are adjusted so that the two infrared receivers 222 are respectively located directly above the set positions A and B of the material belt 1, so that one infrared emitter 221, point A, and one infrared receiver 222 are located on the same vertical line, and so that one infrared emitter 221, point B, and one infrared receiver 222 are located on the same vertical line.

[0163] The material strip 1 passes through the deflection correction and cutting mechanism 2. When the infrared rays emitted by the infrared emitters 221 of one group of the detection components 22 cannot be received by the infrared receiver 222, it means that one side of the material strip 1 exceeds the line where the set position point A or point B is located, that is, the position of the material strip 1 is offset, but the size does not exceed the set size. At this time, the deflection correction plate 23 starts to work. The first pushing member 25 pushes the deflection correction plate 23 to move along the first feed fixing rod 27, and pushes the material strip 1 to the line where the set position point A or point B is located, and makes its edge coincide with the line where point A or point B is located, and then the deflection correction plate 23 stops. When the infrared emitters 221 on both sides of the material strip 1 are blocked at the same time or are not blocked, the deflection correction plate 23 returns to its original position and does not work. Since the lowest point of the correcting plate 23 is lower than the height of the material strip 1 and the highest point of the correcting plate 23 is higher than the height of the material strip 1 , when the correcting plate 23 contacts the material strip 1 , the correcting plate 23 can push the material strip 1 .

[0164] When the infrared rays emitted by the infrared emitters 221 of both detection assemblies are simultaneously unable to be received by the infrared receivers 222, it indicates that both sides of the material strip 1 have exceeded the set size, and the portion of the material strip 1 that exceeds the set size is the portion that exceeds the set size. At this point, the cutting blades 24 begin operation. The second pusher 26 propels the cutting blades 24 along the second feed fixing rod 28, pushing them to the set position lines A and B, respectively, positioning them below the material strip 1 with their blades facing upward. Because the surface of the cutting blades 24 is 0.1 mm above the surface of the material strip 1, relative motion occurs between the material strip 1 and the cutting blades 24 as the material strip 1 advances, allowing the cutting blades 24 to remove the portion of the material strip 1 that exceeds the set size. This portion of the material strip 1 that exceeds the set size does not limit the movement of the cutting blades 24, causing them to become stuck. Furthermore, the portion of the strip 1 removed by the cutter 24 that exceeds the set size is typically less than 1 mm. Therefore, the effect of the portion exceeding the set size on the cutter 24 is further reduced, and no limiting effect occurs. The cutter 24 can smoothly move to the set position line at point A and point B. When the infrared emitters 221 at both ends of the strip are not simultaneously blocked, the cutter 24 returns to its original position and does not operate.

[0165] When the infrared emitters 221 at both ends of the material strip 1 are not shielded, the deflection correction plate 23 and the cutting knife 24 do not work, and the material strip 1 moves normally to the next station. When the material strip 1 is composed of a multi-layer structure, the second layer structure of the material strip is bonded by the bonding mechanism 6, and then the die-cutting mechanism 4 is used for die-cutting. After the die-cutting is completed, the spare parts product is prepared, and the material strip 1 moves forward until it abuts against the rolling surface of the pulling roller 51. One end of the material strip 1 passes through the gap between the pulling roller 51 and the pressing roller 52 and enters the winding device, completing the process. When the material strip 1 is a single-layer structure, the material strip 1 does not pass through the bonding mechanism 6, but directly enters the die-cutting mechanism 4 for die-cutting. The number and structure of the die-cutting mechanism 4 and the bonding mechanism 6 can be set according to the actual process conditions.

The control system utilizes a PLC, facilitating automated control and operation of the die-cutting machine.
