Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, and in particular to a die-cutting tool structure with die-cutting waste removal function. Background Technology

[0002] Die-cutting technology is widely used in packaging printing, electronic materials, automotive interiors, medical devices, and other fields. Its core is to precisely cut paper, plastics, metal foils, composite materials, etc., into shapes using die-cutting tools. During the cutting process, in addition to the target product, a large amount of waste is generated, such as edge scraps and perforated waste. If the waste is not removed in time, it will directly affect subsequent production processes.

[0003] The prior art patent document CN215849900U discloses a die-cutting machine tool structure for carton processing, including a fixed base and a tool body fixedly mounted on the die-cutting machine body. A fixing block is fixedly connected to one side of the tool body. The outer periphery of the fixed base has an installation groove communicating with the bottom, and the installation groove extends to one side to form a fixing groove. An arc-shaped block is fixedly connected to the outer periphery of the fixing block. A first grooved plate is also fixedly connected to the outer periphery of the fixed base, and an insert plate is slidably connected within the first grooved plate. A second grooved plate is fixedly connected to the outer periphery of the fixing block. In this invention, when installing the tool body, simply insert the fixing block into the fixed base and rotate it. Then, by adapting the insert plate to the second grooved plate, the tool body can be installed. The reverse operation completes the disassembly of the tool body, thus facilitating the replacement of the tool body.

[0004] While existing technologies facilitate the replacement of the cutting tool body, waste generated during the die-cutting process tends to accumulate and adhere to the inside and outside of the blade. This waste requires manual cleaning using tools such as tweezers and air guns, which is not only cumbersome and time-consuming, but also prone to blade damage or waste debris residue due to improper operation in precision die-cutting scenarios, affecting the accuracy of subsequent processing. This makes it difficult to meet people's needs and has low practicality. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a die-cutting tool structure with die-cutting waste removal function, including a support base, a movable rod fixedly connected to the top of the support base, a mounting frame fixedly connected to the other end of the movable rod, a scraping mechanism inside the mounting frame, waste removal mechanisms on the left and right sides of the support base, and running mechanisms on the front and rear sides of the support base. The scraping mechanism includes a mold, multiple limiting rods fixedly connected inside the mold, a blade fixedly connected to the bottom of the mold, an outer frame slidably connected to the outside of the blade, a limiting block fixedly connected to the top of the outer frame, a return spring sleeved inside the limiting block, an arc-shaped locking block slidably connected to the outside of the limiting block, an inner frame slidably connected to the inside of the blade, a support spring assembly fixedly connected to the top of the inner frame, and a mounting assembly threadedly connected inside the mounting frame.

Multiple adsorption tubes are fixedly connected to the top of the air pump, and suction ports are fixedly connected to the other ends of the adsorption tubes. An expansion port is fixedly connected to the outside of the suction ports. A connecting pipe is fixedly connected to the outside of the air pump, and the other end of the connecting pipe is fixedly connected to the outside of the receiving pump. A mounting frame is fixedly connected to the top of the receiving pump, and multiple nozzles are fixedly connected to the top of the mounting frame. The other ends of the nozzles are fixedly connected to the outside of the receiving pump.

[0008] The operating mechanism includes a feeding plate and a discharging plate. The feeding plate is fixedly connected to the outside right side of the support base, and the discharging plate is fixedly connected to the outside left side of the support base. An edge roller is rotatably connected to the top of the discharging plate, i.e., the side away from the support base.

The outer side of the pins is slidably connected to the inside of the mounting frame, and the adjacent side of the pins is slidably connected to the outer inner side of the mold.

[0012] The nozzle and the suction port are horizontally parallel, and the receiving end of the push rod cylinder is fixedly connected to the outside of the air pump.

[0015] 1. In this utility model, through the sliding cooperation between the outer frame sleeved on the outside of the blade and the limiting rod, when the blade cuts downwards, the outer frame slides upwards due to the contact material, compressing the return spring. When the blade returns to its original position, the return spring drives the outer frame to slide downwards, thereby realizing the automatic scraping of waste material on the outside of the blade by the outer frame, avoiding the waste material from sticking and affecting the die-cutting accuracy. Through the sliding cooperation between the inner frame slidably connected inside the blade and the limiting rod, the support spring group provides support force to the inner frame, making it continuously slide in contact with the inside of the blade, thereby realizing the synchronous removal of residual waste material on the inside of the blade by the inner frame, ensuring the cleanliness of the die-cutting area, thus solving the problems of waste material residue, sticking, and tedious manual waste removal on the inside and outside of the blade during the die-cutting process, and realizing the automated synchronous removal of waste material on the inside and outside of the blade.

[0016] 2. In this utility model, with the air pump connected to the suction port and expansion port through the adsorption tube, the waste generated during the die-cutting process is efficiently collected through negative pressure adsorption. With the receiving pump and the nozzle fixed by the mounting bracket, the filtered clean airflow is transformed into a high-speed sweeping airflow that acts on the die-cutting area. With the coordinated cooperation of the push rod cylinder and the air pump, the waste removal process and the die-cutting action are synchronized, so as to solve the problems of large-area waste being difficult to collect efficiently during the cutting process, residual fine waste or dust affecting the quality of the finished product, and the low efficiency caused by the disconnect between the waste removal process and the die-cutting action.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a die-cutting tool structure with die-cutting waste removal function, including a support base 1, the support base 1 as the basic load-bearing component of the entire die-cutting tool structure, a movable rod 2 fixedly connected to the top of the support base 1, the movable rod 2 connecting the support base 1 and the mounting frame 3, realizing the vertical adjustment of the mounting frame 3, the other end of the movable rod 2 is fixedly connected to the mounting frame 3, the mounting frame 3 as the carrier of the scraping mechanism 6 and the mounting component 4, fixing the mold 61 and providing an adjustment interface, the scraping mechanism 6 is provided inside the mounting frame 3, the waste removal mechanism 7 is provided on the left and right sides of the support base 1, and the running mechanism 5 is provided on the front and rear sides of the support base 1;

[0027] The scraping mechanism 6 includes a mold 61, which serves as the main frame of the scraping mechanism 6. Multiple limiting rods 62 are fixedly connected inside the mold 61, providing linear motion guidance to prevent offset or rotation during sliding. A blade 63 is fixedly connected to the bottom of the mold 61. The blade 63 is the core cutting component, using its sharp edge to die-cut and separate the material. An outer frame 64 is slidably connected to the outside of the blade 63, fitting around the blade 63 and scraping away waste material from the outside of the blade 63 through sliding contact. It also serves as the force-bearing carrier for the return spring 66. A limiting block 65 is fixedly connected to the top of the outer frame 64, fixing the return spring 66 and limiting the sliding stroke of the outer frame 64. A return spring 66 is fitted inside the limiting block 65. The positioning spring 66 and the reset spring 66 provide a reset driving force for the outer frame 64, realizing the automation of the waste scraping action. The external sliding connection of the limiting block 65 is an arc-shaped locking block 67, which is fixed to the inner wall of the mold 61 to provide sliding restriction for the limiting block 65 and prevent the limiting block 65 from exceeding the limit position during sliding. The inner frame 68 is slidably connected to the inside of the blade 63. The inner frame 68 is slidably connected to the inside of the blade 63. The supporting spring assembly 69 pushes to remove the waste residue on the inside of the blade 63. The top of the inner frame 68 is fixedly connected to the supporting spring assembly 69, which provides support force for the inner frame 68 to ensure that the inner frame 68 slides in contact with the inside of the blade 63 and realizes waste removal. The mounting frame 3 is internally threaded with a mounting component 4.

[0028] Mounting assembly 4 includes multiple adjusting bolts 42. The adjusting bolts 42 drive the pins 41 to move laterally, thereby adjusting and clamping the position of the mold 61 within the mounting frame 3. The external parts of the multiple adjusting bolts 42 are threaded to the front and rear sides of the mounting frame 3, and the adjacent sides of the multiple adjusting bolts 42 are rotatably connected to the pins 41. The pins 41 are inserted into the slots on the outside of the mold 61, thereby achieving quick positioning and fixing of the mold 61 and the mounting frame 3. The external parts of the pins 41 are slidably connected to the inside of the mounting frame 3, and the adjacent sides of the pins 41 are slidably connected to the inner side of the outside of the mold 61.

[0029] The other ends of the two limiting rods 62 are slidably connected to the top inner side of the outer frame 64, the other ends of the multiple limiting rods 62 are slidably connected to the top inner side of the inner frame 68, the two ends of the arc block 67 are fixedly connected to the inner wall of the mold 61, and the other end of the support spring assembly 69 is fixedly connected to the bottom inner side of the mold 61.

[0030] like Figure 1 , Figure 2 and Figure 6As shown, the waste removal mechanism 7 includes an air pump 71 and a receiving pump 76. The air pump 71 generates negative pressure airflow, which adsorbs waste generated during the die-cutting process through the adsorption tube 72 and the suction port 73, achieving preliminary collection of waste. The air pump 71 is externally fixedly connected to the front side of the support base 1, and the receiving pump 76 is externally fixedly connected to the rear side of the support base 1. The receiving pump 76 receives the waste and airflow delivered by the air pump 71, collects the waste through internal filtration, and discharges the clean airflow through the nozzle 78, realizing airflow recycling. Multiple adsorption tubes 72 are fixedly connected to the top of the air pump 71. The adsorption tubes 72 connect the air pump 71 to the suction port 73, transmitting negative pressure airflow and waste. The other end of the multiple adsorption tubes 72 is fixedly connected to the suction port 73. The suction port 73 adsorbs waste through negative pressure, and its shape matches the edge of the die-cut product. An expansion port 74 is fixedly connected to the outside of the suction port 73. An expansion port 74 enlarges the effective adsorption area of ​​the suction port 73. A connecting pipe 75 is fixedly connected to the outside of the air pump 71, connecting the air pump 71 and the receiving pump 76 to transmit waste and airflow. The other end of the connecting pipe 75 is fixedly connected to the outside of the receiving pump 76. A mounting bracket 77 is fixedly connected to the top of the receiving pump 76. The mounting bracket 77 fixes the nozzle 78 and adjusts its angle to ensure that the nozzle 78 is parallel and aligned with the suction port 73, so as to achieve the precise action of the blowing airflow on the die-cutting area. Multiple nozzles 78 are fixedly connected to the top of the mounting bracket 77. The nozzles 78 convert the clean airflow discharged from the receiving pump 76 into high-speed blowing airflow to remove the fine waste or dust remaining in the die-cutting area. The other end of the nozzle 78 is fixedly connected to the outside of the receiving pump 76. The nozzle 78 is horizontally parallel to the suction port 73. The receiving end of the push rod cylinder 58 is fixedly connected to the outside of the air pump 71.

[0031] like Figure 1 , Figure 2 and Figure 6As shown, the operating mechanism 5 includes a feeding plate 51 and a discharging plate 52. The feeding plate 51 serves as the input platform for the die-cutting material, fixing the feeding roller 56 and guiding the material smoothly into the die-cutting area. A push rod cylinder 58 is also fixedly connected to its top. The outside of the feeding plate 51 is fixedly connected to the right side of the support base 1, and the outside of the discharging plate 52 is fixedly connected to the left side of the support base 1. The discharging plate 52 serves as the output platform for the die-cut finished product, fixing the extrusion roller 57 and the collection frame 54. A corner roller 53 is rotatably connected to the top of the discharging plate 52, i.e., the side away from the support base 1. The corner roller 53 winds up the continuous waste material from the outside. A collection frame 54 is fixedly connected to the bottom of the discharging plate 52. The collection frame 54 is located at the bottom of the discharging plate 52 and collects the die-cut material. An outlet 55 is slidably connected to the inner bottom of the collection frame 54. The material outlet 55 controls the timed discharge of materials through sliding control. Push rod cylinders 58 are slidably connected to both sides of the top of the discharge area plate 52. The push rod cylinders 58 serve as the power source for the mounting frame 3 and drive the scraping mechanism 6 to move up and down through reciprocating linear motion. A connecting plate 59 is fixedly connected to the output end of the push rod cylinder 58. The connecting plate 59 connects the push rod cylinder 58 and the mounting frame 3, transmits the cylinder driving force, and ensures that the mounting frame 3 is subjected to uniform force. The other end of the connecting plate 59 is threaded into the interior of the mounting frame 3. A feeding roller 56 is fixedly connected to the top of the feeding area plate 51 near the support base 1. The feeding roller 56 drives the die-cutting material to be conveyed to the die-cutting area. An extrusion roller 57 is fixedly connected to the top of the discharge area plate 52, near the support base 1. The extrusion roller 57 separates the die-cut finished product from the waste material, ensuring that the finished product is output intact and guided to fall into the collection box 54.

[0032] Working principle: In the operating mechanism 5, the feeding roller 56 at the top of the feeding area plate 51 drives the die-cutting material to be conveyed to the die-cutting area. The extrusion roller 57 at the top of the discharge area plate 52 separates the die-cut finished product from the waste material. The finished product falls into the collection frame 54 at the bottom. The discharge port 55 on the inner side of the bottom of the collection frame 54 can slide to control the timed discharge of materials. The corner roller 53 rotates to roll up the continuous waste material outside. The output end of the push rod cylinder 58 at the top of the feeding area plate 51 and the discharge area plate 52 is threadedly connected to the mounting frame 3 through the connecting plate 59. As a power source, it drives the mounting frame 3 to reciprocate along the movable rod 2 in the vertical direction. The movable rod 2 connects the support base 1 and the mounting frame 3 to realize the vertical adjustment of the mounting frame 3.

[0033] Inside the mounting frame 3, in the mounting assembly 4, adjusting bolts 42 are threadedly connected to the front and rear sides of the mounting frame 3. Rotating the adjusting bolts 42 drives the pins 41 to move laterally. The pins 41 are inserted into the slots on the outside of the mold 61, allowing the mold 61 to be adjusted and clamped within the mounting frame 3. When the mounting frame 3 moves the mold 61 downwards, the blade 63 at the bottom of the mold 61 acts as the core cutting component, performing die-cutting and separation of the material. The outer frame 64 is fitted over the blade 63 and slidably connected. The other ends of the two limiting rods 62 are slidably connected to the inner top of the outer frame 64, providing linear motion guidance for the outer frame 64. The limiting block 65 is fixed to the outer frame 64 inside the mold 61 and slidably connected to the arc-shaped locking block 67. Both ends of the arc-shaped locking block 67 are fixed to the mold. The inner wall of 61 has a limiting block 65 that restricts the sliding stroke of the outer frame 64. The return spring 66 inside the limiting block 65 provides a return driving force for the outer frame 64. When the blade 63 cuts downward, the outer frame 64 slides upward due to contact with the material, compressing the return spring 66. When the blade 63 completes the cutting and returns upward, the return spring 66 drives the outer frame 64 to slide downward, scraping away the waste material on the outside of the blade 63. The inner frame 68 is slidably connected inside the blade 63. The other end of multiple limiting rods 62 is also slidably connected to the top inner side of the inner frame 68. The other end of the support spring group 69 at the top of the inner frame 68 is fixed to the bottom inner side of the mold 61. The support spring group 69 provides support force to the inner frame 68, making it slide in contact with the inner side of the blade 63, and removing the waste material remaining on the inner side of the blade 63 during the die-cutting process.

[0034] In the waste removal mechanism 7, the air pump 71 is fixed to the front of the support base 1 to generate negative pressure airflow. Multiple adsorption tubes 72 at the top are connected to the suction port 73. The expansion port 74 outside the suction port 73 expands the effective adsorption area. Waste generated during the die-cutting process is adsorbed by negative pressure. The waste and airflow are transmitted through the connecting pipe 75 to the receiving pump 76 fixed to the rear of the support base 1. The receiving pump 76 filters and collects the waste. The clean airflow is discharged through the nozzle 78 on the top mounting bracket 77. The mounting bracket 77 fixes the nozzle 78 and adjusts its angle so that the nozzle 78 is horizontal and parallel to the suction port 73, converting the clean airflow into a high-speed sweeping airflow to remove the fine waste or dust remaining in the die-cutting area and realize the airflow recycling. The receiving end of the push rod cylinder 58 is fixed to the outside of the air pump 71 and works in conjunction with the air pump 71 to ensure that the entire waste removal process is synchronized with the die-cutting action.
