Description

Technical Field

[0001] This invention belongs to the field of die-cutting equipment technology, specifically relating to a safe material receiving device for a circular die-cutting machine. Background Technology

[0002] Circular die-cutting equipment is a highly efficient and precise die-cutting tool in modern industry. It uses a rotating cylindrical die and pressure rollers to continuously die-cut various materials at high speed. This design not only significantly improves production efficiency but also ensures smooth and flat die-cut edges and dimensional accuracy. Its unique multi-layer composite die-cutting capability can easily handle complex process requirements such as electronic components and packaging materials, achieving one-time forming and automatic waste removal. Combined with an intelligent tension control system, it effectively avoids material deformation and ensures production stability, making it ideal equipment for pursuing high-quality and high-efficiency die-cutting processing.

[0003] Currently, there are various methods available for separating and collecting die-cut materials on the market, such as using air blowing or suction devices, or using ejector pins to eject materials. However, in practice, after the die-cutting process, the edges of the material to be collected often exhibit slight adhesion to the waste material. Furthermore, during the cutting process, it is difficult to ensure that the cutting depth is consistent across all edges. Therefore, when using the conventional methods for separation, it is possible that most of the material's edges have detached from the waste material, but a small portion remains adhered. In such cases, the ejector pins may fail to eject the material accurately and may miss the target. Simultaneously, the suction force of suction and blowing methods weakens due to variations in the area of ​​the material subjected to suction, significantly reducing the separation effect. Based on this, the present invention is proposed to improve upon these issues. Summary of the Invention To achieve the above objectives, this invention provides a safe material receiving device for a circular die-cutting machine, comprising: a worktable, on which a placement frame and a support frame are respectively provided; a first feeding roller and a receiving roller are respectively provided on the support frame; a second feeding roller, a pressing roller, and a die-cutting assembly are respectively provided on the worktable; a support platform is provided on the worktable, and a support assembly is provided on the support platform; a cylinder is provided on the support assembly, and a pressure plate is provided at the output end of the cylinder; a tensioning assembly and multiple sets of push rod assemblies are respectively connected below the pressure plate, and the tensioning assembly is located on both sides of the push rod assembly; a receiving box for receiving material pushed down by the push rod assembly is placed on the placement frame; when the push rod assembly moves down to contact the material, the material is absorbed by the push rod assembly and pushed away as waste; when the push rod assembly rises, the push rod assembly blows gas to blow the material into the receiving box; when the push rod assembly moves down, the tensioning assembly pulls the material located below the push rod assembly to flatten it to both sides.

[0004] In one possible implementation, the die-cutting assembly includes a support wall, which is slidably connected to a circular die and an extrusion roller via a slider. A transmission roller is rotatably connected to the support wall, and a limiting block is provided at the top of the support wall. An extrusion rod is threadedly connected to the limiting block.

[0005] In one possible implementation, the circular die is provided with driven teeth, the transmission roller is provided with a servo motor, and the output end of the servo motor is connected to a gear, which meshes with the driving teeth.

[0006] In one possible implementation, a limiting platform is provided on the support platform, a support platform is provided above the limiting platform, a top plate is provided above the support platform, and the cylinder is located on the top plate.

[0007] In one possible implementation, the push rod assembly includes a piston cylinder, a connecting block, and a push rod mold. The piston cylinder is fixedly connected to a support platform, the connecting block is slidably connected to a limiting platform, the push rod mold is threaded to the connecting block, a piston plate is slidably connected inside the piston cylinder, and the piston plate and the connecting block are connected to a pressure plate via the same connecting rod.

[0008] In one possible implementation, the connecting block has a cavity, the top end of the piston cylinder is connected to an air supply pipe, the other end of the air supply pipe is connected to the cavity, the bottom end of the ejector mold is provided with a suction cup, the ejector mold has a second air passage, and the connecting block has a first air passage. When the ejector mold is installed on the connecting block, the first air passage is connected to the second air passage. When the connecting block moves down, air is drawn in by the suction cup and flows into the piston cylinder. When the connecting block moves up, the air in the piston cylinder is compressed and ejected from the suction cup.

[0009] In one possible implementation, a sliding block is slidably connected within the connecting block, the sliding block has a through hole, and the sliding block also has a blocking block. A second compression spring connects the sliding block and the connecting block. A connecting pipe connects adjacent connecting blocks. A limiting sleeve is provided on the ejector mold. When no ejector mold is installed below the connecting block, the through hole is connected to the first air passage. When no ejector mold is installed below the connecting block, the first air passage is blocked by the blocking block, and the air in the piston cylinder flows to the adjacent connecting block where the ejector mold is installed.

[0010] In one possible implementation, the tensioning assembly includes a push plate, a sliding plate, a sliding support rod, a tensioning roller, and a first compression spring. The push plate and the sliding plate are connected by the first compression spring, the push plate is connected to a pressure plate, the sliding support rod is slidably connected to the sliding plate, and the tensioning roller is rotatably connected to the sliding support rod.

[0011] In one possible implementation, the top rod assembly is provided with a connecting support rod, and a rotating rod is rotatably connected to the connecting support rod via a rotating shaft. The other end of the rotating rod is rotatably connected to a sliding plate via a rotating shaft. When the pressure plate moves down, the sliding support rod and the tension roller move to both sides, and the material located below the top rod assembly is flattened.

[0012] In one possible implementation, a limit roller is rotatably connected to the support platform, the support platform is provided with an inspection port, and the support platform is connected to the receiving box below.

[0013] The significant technical effects of the embodiments of the present invention are as follows: 1. In this equipment, by setting up a piston cylinder, air supply pipe, piston plate, connecting block, top rod mold and suction cup, the top rod mold can adsorb the material when pressing and separating the material, thereby improving the separation effect of material and waste, reducing the probability of separation failure due to the tight adhesion between the material and waste, and also blowing the separated material away from the suction cup after separation, avoiding the material from sticking to the suction cup.

[0014] 2. In this equipment, by setting up a push plate, a sliding plate, a sliding support rod and a tensioning roller, the material can be pulled to both sides to a certain extent without affecting the material transfer, ensuring that the separated material is in a tense and flat state, which is more conducive to the contact and adsorption between the suction cup and the material.

[0015] 3. In this equipment, multiple push rod assemblies are set up and connected together, and a sliding block is set in the connecting block. This allows the user to adjust the number of push rod molds installed according to the position and size of the material to be cut. At the same time, the suction force at the suction cup will also be automatically adjusted according to the number of installations, thus making it more suitable for different working scenarios.

[0026] Please see Figures 1-10This illustration shows a safe material receiving device for a circular die-cutting machine according to an embodiment of the present invention, including a worktable 1, on which a placement frame 11 and a support frame 12 are respectively provided. A first feeding roller 13 and a receiving roller 16 are respectively provided on the support frame 12. A second feeding roller 14, a pressing roller 15, and a die-cutting assembly 2 are respectively provided on the worktable 1. A support platform 3 is provided on the worktable 1, and a support assembly 4 is provided on the support platform 3. A cylinder 44 is provided on the support assembly 4, and a pressure plate 45 is provided at the output end of the cylinder 44. Below 45 are tensioning components 5 and multiple sets of push rod components 6, with tensioning components 5 located on both sides of push rod components 6; a receiving box 33 is placed on the placement frame 11 to catch the material pushed down by the push rod components 6; when the push rod components 6 move down and contact the material, the material is adsorbed by the push rod components 6 and pushed away from the waste; when the push rod components 6 rise, the push rod components 6 blow out gas to blow the material into the receiving box 33; when the push rod components 6 move down, the tensioning components 5 pull the material located below the push rod components 6 to flatten it to both sides.

[0027] More detailed, such as Figure 2 As shown, the material is pulled out from the first feeding roller 13 and the second feeding roller 14 respectively, and pressed together at the pressing roller 15 to complete the bonding. Then the material is cut by the die-cutting assembly 2. After cutting, the cut material is separated and falls into the receiving box 33 below when passing through the support table 3, while the excess waste material is rolled up by the receiving roller 16. However, in the existing technology, when separating the cut material, such as by ejecting the material with an ejector pin or by suction or blowing, there is a problem that the material is subjected to force when being separated. Uneven cutting or inconsistent cutting depths at the material edges can cause material to detach from the waste material from one side first, and then, due to inertia, the remaining portion will detach from the waste material. If the adhesion between the material and the waste material is even slightly high, it may be impossible to completely separate the material from the waste material. To reduce this situation, this device is equipped with a push rod assembly 6 and a tensioning assembly 5 on the support component 4. When the cylinder 44 pushes the pressure plate 45 downwards, the pressure plate 45 simultaneously drives the push rod assembly 6 and the tensioning assembly 5 downwards. Figure 3 and Figure 7 As shown, when the push rod assembly 6 moves down, it generates a continuous suction force when it comes into contact with the material, adsorbing the material to be separated onto the lower end of the push rod assembly 6 and moving down with it. This means that even if the material is not completely separated from the waste by the push rod assembly 6, it will be pulled down by the push rod assembly 6 due to adsorption, thus completing the separation from the waste. When the push rod assembly 6 returns to its original position, in order to prevent the material from sticking to the bottom of the push rod assembly 6 and being carried back, the end of the push rod assembly 6 will spray gas downward to blow the material into the receiving box 33 below. like Figure 5 and Figure 6As shown, the bottom of the tensioning component 5 presses the material against the top of the support platform 3. When the pressure plate 45 moves down, the tensioning component 5 will slightly pull the material to both sides to flatten it, thereby ensuring the flatness of the material under the top rod component 6 when it is adsorbed, thus ensuring that the top rod component 6 can complete the adsorption of the material.

[0028] Please see Figure 2 and Figure 4 In some embodiments, the die-cutting assembly 2 includes a support wall 21, which is slidably connected to a circular die 23 and an extrusion roller 22 via a slider. A transmission roller 24 is rotatably connected to the support wall 21, and a limiting block 28 is provided at the top of the support wall 21. An extrusion rod 27 is threadedly connected to the limiting block 28.

[0029] Please see Figure 2 and Figure 4 In some embodiments, the circular die 23 is provided with driven teeth 231, the transmission roller 24 is provided with servo motor 25, the output end of the servo motor 25 is connected to gear 26, and gear 26 meshes with driving teeth 241.

[0030] More specifically, the transmission roller 24 is rotatably connected to the support wall 21, and both ends of the circular die 23 and the extrusion roller 22 are rotatably connected to sliding support blocks. The sliding support blocks slide on the support wall 21 and can be removed from the support wall 21, so that the user can easily replace the die-cutting tool. The limiting block 28 is engaged with the protrusion on the top of the support wall 21. The user can adjust the position of the extrusion rod 27 in the vertical direction by rotating the extrusion rod 27, thereby limiting the extrusion of the extrusion roller 22, and thus limiting the extrusion of the circular die 23. The servo motor 25 drives the gear 26 to rotate, which in turn drives the transmission roller 24 to rotate, and then drives the circular cutter mold 23 to rotate, thereby cutting the material passing between the circular cutter mold 23 and the transmission roller 24.

[0031] Please see Figure 5 In some embodiments, a limiting platform 41 is provided on the support platform 3, a support platform 42 is provided above the limiting platform 41, a top plate 43 is provided above the support platform 42, and a cylinder 44 is provided on the top plate 43.

[0032] Please see Figure 7 and Figure 8 In some embodiments, the push rod assembly 6 includes a piston cylinder 61, a connecting block 62, and a push rod mold 63. The piston cylinder 61 is fixedly connected to the support platform 42, the connecting block 62 is slidably connected to the limiting platform 41, the push rod mold 63 is connected to the connecting block 62 by threads, and a piston plate 611 is slidably connected inside the piston cylinder 61. The piston plate 611 and the connecting block 62 are connected to the pressure plate 45 by the same connecting rod.

[0033] Please see Figure 7 and Figure 8 In some embodiments, a cavity 621 is provided inside the connecting block 62, and an air supply pipe 64 is connected to the top end of the piston cylinder 61. The other end of the air supply pipe 64 is connected to the cavity 621. A suction cup 632 is provided at the bottom end of the push rod mold 63, and a second air passage 633 is provided inside the push rod mold 63. A first air passage 622 is provided on the connecting block 62. When the push rod mold 63 is installed on the connecting block 62, the first air passage 622 is connected to the second air passage 633. When the connecting block 62 moves down, air is drawn in by the suction cup 632 and flows into the piston cylinder 61. When the connecting block 62 moves up, the air in the piston cylinder 61 is compressed and ejected from the suction cup 632.

[0034] More specifically, the support component 4, as a whole, serves as a support and limiting component for the top rod component 6, and is fixedly installed on the support platform 3, such as... Figure 5 and Figure 8 As shown, the piston cylinder 61 is fixed on the support platform 42, and the connecting block 62 is slidably connected to the limiting platform 41. The connecting block 62 is connected to the pressure plate 45 through the piston cylinder 61 via a connecting rod. The piston plate 611 is also connected to the connecting rod, so that the piston plate 611 and the connecting block 62 move synchronously. Figure 8 The push rod assembly 6 is shown in its initial state. When the cylinder 44 pushes the pressure plate 45 down, the piston plate 611, connecting block 62 and push rod mold 63 move down synchronously. At this time, air enters the cavity 621 through the second air passage 633 and the first air passage 622 and enters the piston cylinder 61 through the air supply pipe 64, thereby generating suction at the suction cup 632. When the suction cup 632 comes into contact with the material, the material is adsorbed and detaches from the waste as the push rod mold 63 moves down. When the cylinder 44 drives the pressure plate 45 up, the air inside the piston cylinder 61 will be ejected from the suction cup 632 along the same path, thereby spraying off the material adhering to the suction cup 632.

[0035] Please see Figure 8 and Figure 9 In some embodiments, a sliding block 71 is slidably connected inside the connecting block 62. The sliding block 71 has a through hole 711 and a blocking block 72. A second compression spring 73 is connected between the sliding block 71 and the connecting block 62. A connecting pipe 65 connects adjacent connecting blocks 62. A limiting sleeve 631 is provided on the push rod mold 63. When the push rod mold 63 is not installed below the connecting block 62, the through hole 711 is connected to the first air passage 622. When the push rod mold 63 is not installed below the connecting block 62, the first air passage 622 is blocked by the blocking block 72, and the air in the piston cylinder 61 flows to the adjacent connecting block 62 where the push rod mold 63 is installed.

[0036] More specifically, the ejector mold 63 is threadedly installed below the connecting block 62. When the ejector mold 63 is not installed below the connecting block 62, even if the connecting block 62 moves down, it cannot touch the material. Generally, multiple pieces of material to be collected may be cut from the same row of materials. Therefore, multiple ejector assemblies 6 are set in the same row. All the cavities 621 of the connecting blocks 62 are connected through the connecting pipe 65. Figure 9 As shown, a sliding block 71 slides inside the connecting block 62. When the ejector mold 63 is installed on the connecting block 62, the limiting sleeve 631 presses the inclined surface on the left side of the sliding block 71, causing the sliding block 71 to move to the right. At this time, the through hole 711 on the sliding block 71 will connect with the first air passage 622. When the ejector mold 63 is removed, the second compression spring 73 pushes the sliding block 71 to the left. At this time, the block 72 will appear in the path of the first air passage 622. The block 72 can be slightly moved inside the sliding block 71. The up-and-down movement of the piston cylinder 61 ensures that the first air passage 622 is blocked regardless of whether it is in the state of suction or blowing. At this time, the suction and blowing of the piston cylinder 61 will act on the adjacent ejector assembly 6 with ejector mold 63 to increase the suction and air jet force. The advantage of this design is that when the number of ejector molds 63 in use decreases, it means that the area and mass of the material cut in the same row will increase. This design can improve the adsorption strength of the material by increasing the suction force accordingly.

[0037] Please see Figure 5 Figure 6 and Figure 7 In some embodiments, the tensioning assembly 5 includes a push plate 51, a sliding plate 52, a sliding support rod 53, a tensioning roller 54, and a first compression spring 55. The push plate 51 and the sliding plate 52 are connected by the first compression spring 55. The push plate 51 is connected to the pressure plate 45. The sliding support rod 53 is slidably connected to the sliding plate 52. The tensioning roller 54 is rotatably connected to the sliding support rod 53.

[0038] Please see Figure 5 and Figure 6 In some embodiments, the top rod assembly 6 is provided with a connecting support rod 57, and a rotating rod 56 is rotatably connected to the connecting support rod 57 via a rotating shaft. The other end of the rotating rod 56 is rotatably connected to the sliding plate 52 via a rotating shaft. When the pressure plate 45 moves down, the sliding support rod 53 and the tension roller 54 move to both sides, and the material located below the top rod assembly 6 is flattened.

[0039] More specifically, the connecting rod 57 is fixedly connected to the connecting block 62. When the pressure plate 45 pushes the connecting block 62 down, the connecting rod 57 moves down synchronously and pushes the sliding rod 53 to move to both sides through the rotating rod 56. At the same time, the pressure plate 45 also pushes the push plate 51 down, and the downward pressure of the first compression spring 55 and the sliding plate 52 increases. This causes the tension roller 54 to increase the downward pressure on the material below while moving to both sides. This allows the material to be pulled to both sides to a certain extent without affecting the material transfer, thus ensuring that the separated material is in a taut and flat state, which makes it easier for the suction cup 632 to contact and adsorb the material.

[0040] Please see Figure 1 , Figure 2 and Figure 3 In some embodiments, a limiting roller 31 is rotatably connected to the support platform 3, the support platform 3 is provided with an inspection port 32, and the support platform 3 is connected to the receiving box 33 below.

[0041] The limiting roller 31 is used to limit the material in the vertical direction to avoid interference from external forces in the vertical direction when the material is being divided. The position of the inspection port 32 corresponds to the position of the push rod assembly 6. The user can install and replace the push rod mold 63 from below through the inspection port 32. The separated material falls directly into the receiving box 33 below through the support platform 3.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of protection of the claims of the present invention.
