Description

Technical Field

[0001] This invention relates to the field of die-cutting machine technology, specifically to a multi-station linkage high-efficiency die-cutting machine. Background Technology

[0002] Flexible circuit board die-cutting machines are high-precision forming equipment specially developed for flexible circuit boards. They can accurately cut rolls or sheets of PI substrate, copper foil, adhesive film, etc., perform irregular hole opening, and composite waste removal in one integrated process. There are no burrs, no delamination, and no heat damage. They are suitable for small-batch, multi-variety and large-batch continuous production of mobile phones, automotive electronics, etc., and can efficiently and stably complete the forming of the shape and functional areas of flexible circuit boards.

[0003] The rolled material needs to be conveyed between the upper and lower die holders via a conveying assembly. The upper die holder closes with the lower die holder via a lifting assembly to cut the rolled material. A cutting die is installed at the bottom of the upper die holder. The cutting die presses the rolled material to complete the cutting. However, the rolled material will bend and deform during the conveying process, and the cutting die will also cause deformation of the rolled material during the pressing process, which will result in irregular finished parts after cutting. Therefore, there is an urgent need for a multi-station linkage high-efficiency die-cutting machine that avoids bending deformation of the rolled material during cutting. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-station linkage high-efficiency die-cutting machine, which solves the problem of bending and deformation of the roll material during the conveying process or when the die presses the roll material for cutting.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-station linkage high-efficiency die-cutting machine, comprising a die-cutting machine body, a lower die base fixedly installed on the top of the die-cutting machine body, a lifting column provided on the top of the lower die base, an upper die base installed on the top of the lifting column, a connecting plate fixedly installed on the outer wall of the die-cutting machine body, a fixed frame installed on the top of the connecting plate, a sliding rod fixedly installed inside the fixed frame, a slider slidably installed on the outer surface of the sliding rod, a first elastic element sleeved on the outer surface of the sliding rod, a lifting frame fixedly installed on the side of the slider away from the fixed frame, a movable frame slidably installed inside the lifting frame, a limit rod fixedly installed at the bottom of the inner wall of the lifting frame, a rotating shaft rotatably installed inside the movable frame, a first connecting sleeve fixedly sleeved on the outer surface of the rotating shaft, a connecting rod fixedly installed at the bottom of the outer surface of the first connecting sleeve, a pressing wheel rotatably installed at the bottom end of the connecting rod, a pressing component installed inside the movable frame, an adjusting component provided on the top of the movable frame, and a conveying component provided outside the connecting plate.

[0006] By adopting the above technical solution, the upper mold base moves up and down to close with the lower mold base, which can cut the rolled material. When the upper mold base moves downward, it can abut against the support plate and drive the lifting frame to move downward together, so that the pressing roller can abut against the rolled material to roll and smooth the rolled material. The pressing plate can abut against the smoothed rolled material for positioning, avoiding bending deformation of the rolled material during cutting, so that the upper mold base can accurately cut the smoothed rolled material.

[0007] Preferably, the slider is slidably installed inside the fixed frame, the top end of the first elastic element is installed at the bottom of the slider, the bottom end of the first elastic element is installed at the bottom of the inner wall of the fixed frame, and a backing plate is fixedly installed on the side of the lifting frame near the upper mold base, with the top end of the backing plate located at the bottom of the upper mold base.

[0008] Preferably, there are two fixing frames, which are symmetrically distributed outside the lifting frame.

[0009] Preferably, the pressing assembly includes a fixed shaft fixedly installed inside the movable frame, a second connecting sleeve fixedly sleeved on the outer surface of the fixed shaft, a plug sleeve fixedly installed on the bottom of the outer surface of the second connecting sleeve, a plug rod slidably installed inside the plug sleeve, a second elastic element installed on the top of the plug rod, the end of the second elastic element away from the plug rod being installed on the top of the inner wall of the plug sleeve, and a pressing plate fixedly installed on the bottom of the plug rod. Two movable frames are provided, and the two movable frames are symmetrically distributed inside the lifting frame.

[0010] Preferably, a third elastic element is installed on the outer wall of the plug sleeve, and the end of the third elastic element away from the plug sleeve is installed on the outer wall of the connecting rod.

[0011] Preferably, the adjusting assembly includes a slide groove and a threaded sleeve opened at the top of the lifting frame, a threaded post connected internally to the threaded sleeve, the threaded post being disposed inside the slide groove, a pressing plate being fixedly installed at the top of the threaded post, and a rotating column being fixedly installed at the top of the pressing plate.

[0012] Preferably, the bottom of the extrusion plate is located at the top of the lifting frame, and the bottom of the threaded sleeve is fixedly installed on the top of the movable frame.

[0013] Preferably, the conveying assembly includes a mounting plate and a mounting frame. A feeding rack is provided on the top of the mounting plate, and a first slide rail is provided on the top of the mounting plate. The mounting frame is located at the bottom of the first slide rail. An adjusting block is slidably installed inside the mounting frame. A threaded rod is threadedly connected inside the adjusting block. A limit post is fixedly installed on the top of the threaded rod, and a positioning groove is provided on the outer surface of the limit post.

[0014] Preferably, the connecting plate has a second slide rail inside, the threaded rod is disposed inside the first and second slide rails, and the bottom of the limiting post is installed on the top of the connecting plate.

[0015] A method for using a multi-station, high-efficiency die-cutting machine includes the following steps: S1. Before feeding the roll material, loosen the threaded column to adjust the position of the moving frame in the lifting frame so that the pressing wheel is aligned with the top of the roll material. Then tighten the threaded column in the opposite direction to fix the moving frame. After the roll material is punched and formed by the punch press and hot-pressed by the three-layer laminating machine, it enters the die-cutting machine body through the feeding frame and passes through the mounting plate, connecting plate, and bottom of the lifting frame in sequence, and is sent to the space between the lower die base and the upper die base. S2. After the coil material is fed, start the main drive assembly of the die-cutting machine to drive the lifting column and the upper die seat to move down. The upper die seat will move down and abut against the backing plate, so that the lifting frame moves down synchronously until the pressing wheel presses against the top surface of the coil material. The coil material is smoothed by the pulling force of the third elastic element. The lifting frame moves down and drives the pressing plate to press against the coil material. The pressing plate presses the plug rod and the second elastic element to retract in the plug sleeve to complete the positioning of the coil material. S3. After the coil is positioned, the upper die base continues to move down, and the die and the lower die base close to cut the smoothed coil. After the cutting is completed, the drive assembly drives each component to reset. The pressing wheel is reset under the action of the third elastic element, and the pressing plate drives the insertion rod to reset under the action of the second elastic element. Then the coil continues to be conveyed. S4. The cut roll material flows out from the discharge end of the die-cutting machine body, is laminated by another three-layer laminating machine, and then enters the rotary die-cutting machine.

[0016] This invention provides a multi-station, high-efficiency die-cutting machine. It has the following advantages: 1. In this invention, the upper mold base moves up and down to close with the lower mold base, which can cut the rolled material. When the upper mold base moves down, it can abut against the abutment plate and drive the lifting frame to move down together, so that the pressing roller can abut against the rolled material and roll it to flatten it. The pressing plate can abut against the flattened rolled material for positioning, avoiding bending deformation of the rolled material during cutting. This achieves the effect of the upper mold base being able to accurately cut the flattened rolled material, improving the quality of rolled material cutting, reducing the yield of defective products, and saving labor costs.

[0017] 2. In this invention, the first elastic element can press the slider upward to reset the lifting frame after it has moved downward, so that the lifting frame can move up and down together with the upper mold base with the help of the abutment plate. The second elastic element can press the retracted pressing plate to reset. The third elastic element can apply tension to the connecting rod to make the pressing wheel fit against the top surface of the coil and roll flat, so as to achieve the effect of facilitating the reset of the lifting frame, pressing plate and pressing wheel.

[0018] 3. In this invention, the connecting plate and the mounting plate can be connected by the limiting post, the threaded rod and the adjusting block, and the distance between the two limiting posts can be adjusted to facilitate the limiting of the side of the coil material of different specifications and the limiting conveying of the coil material.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to the appendix. Figure 1 - Appendix Figure 7This invention provides a multi-station linkage high-efficiency die-cutting machine, including a die-cutting machine body 1. A lower die base 11 is fixedly installed on the top of the die-cutting machine body 1. A lifting column 12 is provided on the top of the lower die base 11. An upper die base 101 is installed on the top of the lifting column 12. A connecting plate 102 is fixedly installed on the outer wall of the die-cutting machine body 1. A fixing frame 103 is installed on the top of the connecting plate 102. A slide rod 104 is fixedly installed inside the fixing frame 103. A slider 105 is slidably installed on the outer surface of the slide rod 104. A first elastic element 106 is sleeved on the outer surface of the slide rod 104. The slider 105 is away from the fixing frame 103. A lifting frame 107 is fixedly installed on one side. A movable frame 108 is slidably installed inside the lifting frame 107. A limit rod 109 is fixedly installed at the bottom of the inner wall of the lifting frame 107. A rotating shaft 110 is rotatably installed inside the movable frame 108. A first connecting sleeve 111 is fixedly sleeved on the outer surface of the rotating shaft 110. A connecting rod 112 is fixedly installed at the bottom of the outer surface of the first connecting sleeve 111. A pressing wheel 113 is rotatably installed at the bottom end of the connecting rod 112. A pressing component is installed inside the movable frame 108. An adjustment component is provided on the top of the movable frame 108. A conveying component is provided on the outside of the connecting plate 102.

[0023] Specifically, the upper die base 101 is positioned above the lower die base 11 on the top of the die-cutting machine body 1 by means of four lifting columns 12 installed at the four corners of the bottom. The bottom of the four lifting columns 12 penetrates into the interior of the die-cutting machine body 1 and connects to the drive component inside the die-cutting machine body 1. Thus, after the drive component of the die-cutting machine body 1 is started, it can drive the four lifting columns 12 to move up and down, so that the die at the bottom of the upper die base 101 can cut the roll material at the top of the lower die base 11. The connecting plate 102 is fixedly installed on one side of the feed end of the outer wall of the die-cutting machine body 1, and the conveying component is installed on the side of the connecting plate 102 away from the die-cutting machine body 1. Thus, the roll material can flow out from the discharge end of the die-cutting machine body 1 through the connecting plate 102 and the lower die base 11 via the conveying component, thus completing the effect of conveying the roll material through the die-cutting machine body 1. The fixing frame 103 is vertically fixedly installed on the top of the connecting plate 102. A slot is opened on one side of the outer wall of the fixing frame 103, allowing the slider 105 to slide inside the fixing frame 103. The top of the sliding rod 104 is fixedly installed on the top of the inner wall of the slot in the fixing frame 103, and the bottom of the sliding rod 104 passes through the slider 105 and is fixedly installed on the bottom of the inner wall of the slot in the fixing frame 103. The first elastic element 106 is sleeved on the outer surface of the sliding rod 104, and the top of the first elastic element 106 is fixedly connected to the bottom of the slider 105. Thus, the slider 105 can move up and down along the sliding rod 104 inside the fixing frame 103. When the slider 105 moves downward, it can squeeze the first elastic element 106, so that the first elastic element 106 can apply an upward squeezing force to the slider 105, which facilitates the slider 105 to rebound and reset. The outer wall of the lifting frame 107 is fixedly connected to the outer wall of the slider 105. Two limiting rods 109 are fixedly installed at the bottom of the inner wall of the lifting frame 107, so that the limiting rods 109 can limit the bottom of the movable frame 108 inside the lifting frame 107, and the movable frame 108 can slide inside the lifting frame 107. The bottom of the movable frame 108 is provided with an opening. The two ends of the rotating shaft 110 are rotatably installed inside the opening of the movable frame 108. The rotation of the rotating shaft 110 can drive the first connecting sleeve 111 and the connecting rod 112 to rotate together. The bottom of the connecting rod 112 is set in an inclined shape. After the pressing wheel 113 at the bottom of the connecting rod 112 is subjected to an upward squeezing force, the connecting rod 112 will drive the first connecting sleeve 111 and the rotating shaft 110 to rotate inside the movable frame 108. When the upper mold base 101 moves downward, it can drive the lifting frame 107 to move downward together, so that the pressing roller 113 abuts against the top surface of the coil material passing the top of the connecting plate 102. After the pressing roller 113 is subjected to upward extrusion force, it can roll outward on the top of the coil material to smooth it. The position of the moving frame 108 inside the lifting frame 107 can be adjusted by the adjusting component, so that the moving frame 108 fits the specification width of the coil material, so that the pressing roller 113 can press down against the top of the coil material to smooth it. The pressing component can position and limit the smoothed coil material, so that the upper mold base 101 and the lower mold base 11 can close the mold to accurately cut the coil material. It should be noted that the internal wiring or structural connections of the die-cutting machine body 1, drive assembly, lifting column 12, lower die base 11 and upper die base 101 are existing technologies, and their working principles are common knowledge to those skilled in the art, and will not be described in detail here.

[0024] First, regarding the question of how the lifting frame 107 rises and falls together with the upper mold base 101, please refer to the appendix. Figure 1 Appendix Figure 3 and attached Figure 4The slider 105 is slidably installed inside the fixed frame 103. The top of the first elastic member 106 is installed at the bottom of the slider 105, and the bottom of the first elastic member 106 is installed at the bottom of the inner wall of the fixed frame 103. The lifting frame 107 is fixedly installed with a backing plate 2 on the side near the upper mold base 101, and the top of the backing plate 2 is set at the bottom of the upper mold base 101.

[0025] There are two fixed frames 103, which are symmetrically distributed outside the lifting frame 107.

[0026] Specifically, sliders 105 are fixedly installed on both sides of the lifting frame 107, allowing the lifting frame 107 to stably move up and down between the two fixed frames 103 with the help of the two sliders 105. The first elastic element 106 can apply an upward squeezing force to the slider 105 when it moves downward. When the lifting frame 107 is no longer subjected to downward squeezing, the first elastic element 106 can squeeze the slider 105 to reset the lifting frame 107. A stop is fixedly installed on the side of the lifting frame 107 near the upper mold base 101. Plate 2 and abutment 2 are configured to be installed horizontally. When the upper die base 101 moves downward, the bottom of the upper die base 101 will abut against the abutment 2, causing the lifting frame 107 to move downward together, so that the upper die base 101 can move downward and drive the lifting frame 107 to move downward together. In the normal state when the die-cutting machine body 1 is not working, the lowest position of the bottom of the pressing roller 113 is lower than the lowest position of the bottom die of the upper die base 101. As a result, the pressing roller 113 will first contact the roll material to press and flatten it, and then the die will cut the flattened roll material.

[0027] Secondly, regarding the question of how to position the coiled material after it has been smoothed by the pressing roller 113, please refer to the appendix. Figure 4 - Appendix Figure 6 The pressing assembly includes a fixed shaft 4 fixedly installed inside the movable frame 108. A second connecting sleeve 41 is fixedly sleeved on the outer surface of the fixed shaft 4. A plug sleeve 42 is fixedly installed on the bottom of the outer surface of the second connecting sleeve 41. A plug rod 43 is slidably installed inside the plug sleeve 42. A second elastic element 44 is installed on the top of the plug rod 43. The end of the second elastic element 44 away from the plug rod 43 is installed on the top of the inner wall of the plug sleeve 42. A pressing plate 45 is fixedly installed on the bottom of the plug rod 43. There are two movable frames 108, which are symmetrically distributed inside the lifting frame 107.

[0028] A third elastic element 46 is installed on the outer wall of the plug sleeve 42, and the end of the third elastic element 46 away from the plug sleeve 42 is installed on the outer wall of the connecting rod 112.

[0029] Specifically, the rotating shaft 110 and the fixed shaft 4 are symmetrically distributed inside the movable frame 108. The fixed shaft 4 is fixedly installed inside the movable frame 108 and cannot rotate. The insertion sleeve 42 is connected to the fixed shaft 4 via the second connecting sleeve 41. The second elastic element 44 is disposed inside the insertion sleeve 42. The top end of the second elastic element 44 is connected to the top of the inner wall of the insertion sleeve 42, and the bottom end of the second elastic element 44 is connected to the top of the insertion rod 43. After the insertion rod 43 is inserted upward into the insertion sleeve 42, the second elastic element 44... The device can apply downward pressure to the plug rod 43. The overall length of the pressing plate 45, the plug rod 43 and the plug sleeve 42 is less than the overall length of the pressing wheel 113 and the connecting rod 112. As a result, when the lifting frame 107 moves downward, the pressing wheel 113 contacts the coil material first to smooth it out, and then the pressing plate 45 presses on the smoothed coil material. Finally, the die contacts the coil material to cut it, achieving the effect of pressing and positioning the coil material smoothed by the pressing wheel 113, which makes it easier for the die at the bottom of the upper die base 101 to cut the positioned coil material. When the pressing roller 113 contacts the coil material to press and smooth it, the pressing roller 113 needs to apply lateral pulling force to smooth the coil material. One end of the third elastic element 46 is connected to the outer wall of the connecting rod 112, and the other end of the third elastic element 46 is connected to the outer wall of the insertion sleeve 42. After the pressing roller 113 presses against the top surface of the coil material, the connecting rod 112 drives the rotating shaft 110 to rotate, which will pull the third elastic element 46. The third elastic element 46 can apply pulling force to the connecting rod 112, so that the pressing roller 113 is pressed tightly against the top surface of the coil material to roll and smooth the coil material. When the lifting frame 107 moves upward and resets, the third elastic element 46 will pull the connecting rod 112 to reset, and the second elastic element 44 will also squeeze the insertion rod 43 to reset. It should be noted that the first elastic element 106, the second elastic element 44 and the third elastic element 46 are all metal helical springs. The first elastic element 106 can apply an upward compressive force to the slider 105, the second elastic element 44 can apply a downward compressive force to the plug rod 43, and the third elastic element 46 can apply a tensile force to the connecting rod 112.

[0030] Furthermore, regarding the question of how the movable frame 108 adjusts its position inside the lifting frame 107, please refer to the appendix. Figure 3 With appendix Figure 6 The adjustment assembly includes a slide groove 3 and a threaded sleeve 31 opened on the top of the lifting frame 107. The threaded sleeve 31 is internally threaded with a threaded post 32. The threaded post 32 is located inside the slide groove 3. A pressing plate 33 is fixedly installed on the top of the threaded post 32. A rotating post 34 is fixedly installed on the top of the pressing plate 33.

[0031] The bottom of the extrusion plate 33 is located on the top of the lifting frame 107, and the bottom of the threaded sleeve 31 is fixedly installed on the top of the movable frame 108.

[0032] Specifically, two slide grooves 3 are opened on the top of the lifting frame 107. The bottom of the threaded sleeve 31 passes through the slide groove 3 and is fixedly installed on the top of the movable frame 108. The top of the threaded sleeve 31 and the top of the lifting frame 107 are kept at the same level. By rotating the rotating column 34, the operator can drive the threaded column 32 to be threadedly connected to the inside of the threaded sleeve 31, so that the bottom of the extrusion plate 33 abuts against the top of the lifting frame 107, thereby achieving the effect of limiting and fixing the movable frame 108 inside the lifting frame 107. The two movable frames 108 are respectively installed below the two slide grooves 3, and each is equipped with a threaded sleeve 31, a threaded column 32, an extrusion plate 33 and a rotating column 34. By loosening the threaded column 32, the position of the two movable frames 108 inside the lifting frame 107 can be adjusted to adapt to the rolls of different widths.

[0033] Finally, regarding the question of how the conveying assembly connects to the connecting plate 102, please refer to the appendix. Figure 1 Appendix Figure 4 With appendix Figure 7 The conveying assembly includes a mounting plate 5 and a mounting frame 51. A feed rack 6 is provided on the top of the mounting plate 5. A first slide rail is provided on the top of the mounting plate 5. The mounting frame 51 is located at the bottom of the first slide rail. An adjusting block 52 is slidably installed inside the mounting frame 51. A threaded rod 53 is threadedly connected inside the adjusting block 52. A limit post 54 is fixedly installed on the top of the threaded rod 53. A positioning groove 55 is provided on the outer surface of the limit post 54.

[0034] The connecting plate 102 has a second slide rail 7 inside, the threaded rod 53 is set inside the first slide rail and the second slide rail 7, and the bottom of the limiting post 54 is installed on the top of the connecting plate 102.

[0035] Specifically, a first through-path slide is provided on the top of the mounting plate 5, and a second through-path slide 7 is provided on the top of the connecting plate 102. Two adjusting blocks 52 are slidably installed inside the mounting bracket 51. The top of the mounting bracket 51 is fixedly installed on the bottom of the mounting plate 5, and the mounting bracket 51 is directly below the first slide. The mounting plate 5 is placed on the bottom of the connecting plate 102, and the first and second slides 7 are aligned vertically, so that the bottom of the threaded rod 53 can pass through the second slide 7 and the first slide and be threadedly connected to the inside of the adjusting block 52 until the limiting post 54 at the top of the threaded rod 53 abuts against the connecting plate 102. The top of 02 achieves the effect of connecting the connecting plate 102 and the mounting plate 5. The bottom of the mounting plate 5 is provided with a support member, which can support the bottom of the mounting plate 5 and keep the mounting plate 5 horizontally fixed on the top of the die-cutting machine body 1. There are two of each of the limiting post 54, threaded rod 53 and adjusting block 52, which can connect the mounting plate 5 and the connecting plate 102 through two points. Loosening the threaded rod 53 can adjust the distance between the two adjusting blocks 52, so that the roll material can be conveyed through the positioning groove 55 opened on the outer surface of the limiting post 54, and the roll material is initially limited and conveyed. It should be noted that two lifting frames 107 can be installed, with the two lifting frames 107 located on both sides of the upper mold base 101 to smooth the coil material.

[0036] Example 2: Please refer to the appendix. Figure 1 - Appendix Figure 6 A method for using a multi-station linkage high-efficiency die-cutting machine includes the following steps: S1. Before feeding the roll material, loosen the threaded column 32 to adjust the position of the moving frame 108 in the lifting frame 107 so that the pressing wheel 113 is aligned with the top of the roll material. Then tighten the threaded column 32 in the opposite direction to fix the moving frame 108. After the roll material is punched and formed by the punch press and hot-pressed by the three-layer laminating machine, it enters the die-cutting machine body 1 through the feeding frame 6 and passes through the mounting plate 5, the connecting plate 102, and the bottom of the lifting frame 107 in sequence, and is sent to the space between the lower die base 11 and the upper die base 101. S2. After the coil material is fed, start the drive assembly of the die-cutting machine body 1 to drive the lifting column 12 and the upper die base 101 to move down. The upper die base 101 moves down and abuts against the abutment plate 2, so that the lifting frame 107 moves down synchronously until the pressing wheel 113 presses against the top surface of the coil material. The coil material is rolled and smoothed by the pulling force of the third elastic element 46. The lifting frame 107 moves down and drives the pressing plate 45 to press against the coil material. The pressing plate 45 presses the plug rod 43 and the second elastic element 44 upward and retracts in the plug sleeve 42 to complete the positioning of the coil material. S3. After the coil is positioned, the upper die base 101 continues to move down, and the die and the lower die base 11 close to cut the smoothed coil. After the cutting is completed, the drive assembly drives each component to reset. The pressing wheel 113 resets under the action of the third elastic element 46, and the pressing plate 45 drives the insertion rod 43 to reset under the action of the second elastic element 44. Then the coil continues to be conveyed. S4. The cut roll material flows out through the discharge end of the die-cutting machine body 1, and after being re-formed by another three-layer laminating machine, it enters the rotary die-cutting machine.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

10. A method of using a multi-station linkage high-efficiency die-cutting machine, characterized in that, A multi-station linkage high-efficiency die-cutting machine according to any one of claims 1-9 includes the following steps: S1. Before feeding the roll material, loosen the threaded column (32) to adjust the position of the moving frame (108) inside the lifting frame (107) so that the pressing wheel (113) is aligned with the top of the roll material. Then tighten the threaded column (32) in the opposite direction to fix the moving frame (108). After the roll material is stamped and formed by the punch press and hot-pressed by the three-layer laminating machine, it enters the die-cutting machine body (1) through the feeding frame (6) and passes through the mounting plate (5), connecting plate (102), and bottom of the lifting frame (107) in sequence, and is sent to the space between the lower die base (11) and the upper die base (101). S2. After the coil material is fed, start the drive assembly of the die-cutting machine body (1) to drive the lifting column (12) and the upper die seat (101) to move down. The upper die seat (101) will move down and abut against the abutment plate (2), so that the lifting frame (107) moves down synchronously until the pressing wheel (113) presses against the top surface of the coil material. The coil material is smoothed by the pulling force of the third elastic element (46). The lifting frame (107) continues to move down and drives the pressing plate (45) to press against the coil material. The pressing plate (45) presses the plug rod (43) and the second elastic element (44) upward to shrink in the plug sleeve (42) to complete the positioning of the coil material. S3. After the coil is positioned, the upper die base (101) continues to move down, and the die and the lower die base (11) close to cut the smoothed coil. After the cutting is completed, the drive assembly drives each component to reset. The pressing wheel (113) is reset under the action of the third elastic element (46), and the pressing plate (45) drives the plug rod (43) to reset under the action of the second elastic element (44). Then the coil continues to be conveyed. S4. The cut roll material flows out through the discharge end of the die-cutting machine body (1), and after being composited by another three-layer laminating machine, it enters the circular knife die-cutting machine.
