Description

Technical Field

[0001] This invention relates to the field of double-sided tape punching and cutting technology, specifically an automated medical double-sided tape punching and cutting machine. Background Technology

[0002] Medical double-sided tape has wide applications in medical devices. It is a specially designed adhesive with properties such as high adhesion, antibacterial properties, and high temperature resistance. It is widely used in the manufacturing and assembly processes of medical devices.

[0003] The medical double-sided tape we currently produce is a type of fixation medical device. Its function is to firmly fix medical devices or surgical drapes to the human body so that they will not easily fall off; especially for surgical incisions where a complete fit and fixation is required.

[0004] Currently, medical surgical double-sided tape is still processed manually: the tape is manually cut to the required size, then transported to a hydraulic punch press for shaping and opening. Waste material is removed from the punched tape, and any adhesion caused by punching is checked before sorting and packaging. This method is not only inefficient and costly, but also results in inconsistent product quality and a high defect rate. While small cross-cutting machines exist for double-sided tape, they lack the specialized equipment to combine punching and cutting for different specifications. Furthermore, many process requirements differ, making them unsuitable for medical surgical double-sided tape. Therefore, an automated medical double-sided tape punching and cutting machine is proposed. Summary of the Invention

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0047] Please see Figure 1-24 In this embodiment of the invention, an automated medical double-sided tape punching and cutting machine includes a base support 1 and a frame 4. The upper end of the base support 1 is sequentially equipped with a feeding mechanism 2 and an automatic correction mechanism 3. The feeding mechanism 2 is specifically the unwinding point of the medical double-sided tape and also the starting point of the device. The automatic correction mechanism 3 is specifically designed to prevent deviation during the unwinding and feeding of the tape roll. Its operation involves left-right swaying for correction (the automatic correction mechanism 3 is prior art and will not be elaborated upon here). The surface of the frame 4 is equipped with a transition buffer mechanism 5 and a punching and feeding mechanism 6 for coordinated use. Under the action of the transition buffer mechanism 5 and the punching and feeding mechanism 6, the medical double-sided tape can be kept in a smooth state during feeding, and the double-sided tape is smoothly conveyed to the punching mechanism 7. The upper end of the frame 4 is equipped with... The double-sided adhesive is processed by a punching mechanism 7, which punches holes of different specifications into the medical double-sided adhesive. An operation panel 8 allows operators to control the equipment. The upper part of the frame 4 is equipped with a waste removal mechanism 9 and a transition frame mechanism 10 for guiding the double-sided adhesive. The waste removal mechanism 9 works in conjunction with the punching mechanism 7 to remove waste material after punching. The transition frame mechanism 10 guides the punched medical double-sided adhesive to the next process. A fixed-length cross-cutting mechanism 11 is installed at the upper part of the frame 4 to cut the finished product to a fixed length. The transition frame mechanism 10 is located between the waste removal mechanism 9 and the fixed-length cross-cutting mechanism 11. A waste hopper 12 is also installed on the frame 4 below the waste removal mechanism 9 to collect debris. Figure 24As shown; the control unit 13 for controlling the rubber cutting machine is installed on the frame 4. All control electrical components are installed here and are connected to the frame 4 in a pull-out manner. When a fault occurs and maintenance is required, it can be pulled out for easy maintenance later.

[0048] Please see Figure 4-5 In one embodiment, in order to ensure smooth movement of the double-sided adhesive during feeding, preferably, the feeding mechanism 2 includes an air shaft 2-2 and a roll of double-sided adhesive 2-1 disposed on the outer periphery of the air shaft 2-2. Safety clamps 2-3 are installed at both ends of the air shaft 2-2. Both safety clamps 2-3 are connected to the upper end of the base bracket 1. A first coupling 2-4 is installed at the end of one of the safety clamps 2-3, and the end of the first coupling 2-4 is connected to the magnetic powder brake 2-5.

[0049] Specifically, the double-sided adhesive roll 2-1 to be processed is placed on top of the air shaft 2-2. Then, the safety chucks 2-3 at both ends of the air shaft 2-2 facilitate loading and unloading (the safety chucks 2-3 provide a fast, accurate, simple, and safe connection device for frequent connection and disengagement actions; they can connect to the air shaft or square steel; there are two installation methods, namely shaft seat type and flange type; in this example, preferably, the shaft seat type is used for easy installation). Next, the safety chucks 2-3 are connected to the first coupling 2-4, which is connected to the magnetic powder brake 2-5. At this time, the magnetic powder brake 2-5 provides a certain braking force to the roll, allowing it to move smoothly during feeding.

[0050] Please see Figure 6-8 In one embodiment, to prevent the fabric from breaking, the transition buffer mechanism 5 preferably includes two buffer slides 5-1. The ends of the two buffer slides 5-1 are each fitted with a fixing plate 5-2 that fixes them to the frame 4. The outer circumferential surfaces of the two buffer slides 5-1 are movably fitted with first linear bearings 5-3. The outer circumferential surfaces of the two buffer slides 5-1 are each fitted with compression springs 5-4 that balance and buffer the first linear bearings 5-3. The adjacent sides of the two first linear bearings 5-3 are each fitted with first mounting plates 5-5. A transition roller 5-6 is provided parallel to and connected to the two first mounting plates 5-5.

[0051] Specifically, the buffer slide 5-1 is detachably connected to the frame 4 via the fixing plate 5-2. By tightening the bolts, the frame 4 is connected to the fixing plate 5-2 for positioning and installation. Conversely, by unscrewing the bolts, the buffer slide 5-1 can be replaced. Secondly, the two ends of the compression spring 5-4 are connected to the fixing plate 5-2 and the first linear bearing 5-3 respectively. The first linear bearing 5-3 can move along the length of the buffer slide 5-1. When the fabric feeding speed suddenly increases or decreases, the fabric on the transition roller 5-6 will experience a temporary imbalance. At this time, the compression spring 5-4 applies a relative reaction force to the transition roller 5-6 to counteract the tension force generated due to the speed mismatch. In most cases, this plays a protective role when replacing new products and debugging the machine, preventing the fabric from breaking.

[0052] Please see Figure 6-8 In one embodiment, preferably, the punching and feeding mechanism 6 includes two connecting plates 6-1 mounted on the surface of the frame 4. A second mounting plate 6-2 is vertically mounted on the upper end of each connecting plate 6-1. A pressure roller 6-3 and a power roller 6-4 are arranged in parallel between the two second mounting plates 6-2. Both ends of the power roller 6-4 are provided with deep groove bearings 6-5 connected to the second mounting plates 6-2. Bearing covers 6-6 are installed on the outer sides of the ends of the power roller 6-4 extending through the second mounting plates 6-2. A motor base 6-8 for fixing the position of the first servo motor 6-7 is mounted on the surface of the frame 4. A first synchronous pulley 6-9 is mounted on the outer circumferential surface of the power roller 6-4. The first synchronous pulley 6-9 is connected to the first servo motor 6-7 via a first synchronous belt 6-10. A first clamping block assembly connected to the pressure roller 6-3 is mounted on the end of the second mounting plate 6-2. The first clamping block assembly includes two... Each of the two second mounting plates 6-2 has an adjusting component at its upper end. A linkage rod 6-11 is provided between the two adjusting components, and two pressure roller adjusting blocks 6-12 are movably mounted on the outer periphery of the linkage rod 6-11. The adjusting component includes a third mounting plate 6-13 mounted on the upper end of the second mounting plate 6-2. The interior of the third mounting plate 6-13 has a movable adjusting plate 6-14. The end of the linkage rod 6-11 is connected to the adjusting plate 6-14. The upper end of the adjusting plate 6-14 has a top rod. The upper end of the third mounting plate 6-13 has a pressure block 6-15. An adjusting screw 6-16 is provided through the upper end of the pressure block 6-15. The end of the adjusting screw 6-16 contacts the upper end of the top rod. A third compression spring 6-17 is sleeved on the outer periphery of the top rod, and the end of the third compression spring 6-17 contacts both the top rod and the adjusting plate 6-14. A handle 6-18 is installed on the end of the outer periphery of the linkage rod 6-11.

[0053] Specifically, the power roller 6-4, a rubber-coated roller, increases friction and acts as a compactor with the pressure roller 6-3. The pressure roller 6-3 is also a rubber-coated roller. The third compression spring 6-17, used in conjunction with the pressure block 6-15 via the adjusting screw 6-16, can adjust the pre-tightening force. The adjusting plate 6-14 is connected to the pressure roller 6-3. The pressure roller adjusting block 6-12, with its waist-shaped cam structure, adjusts the adjusting plate 6-14 up and down, thereby causing the pressure roller 6-3 to disengage and engage / disengage. For convenient material feeding, a pair of pressure roller adjusting blocks 6-12 are connected to the adjusting linkage rod 6-11. The adjusting linkage rod 6-11 is manually... Handle 6-18 facilitates operation; power roller 6-4 and pressure roller 6-3 are mounted on the second mounting plate 6-2, and the overall structure is fixed to the frame 4 by the second mounting plate 6-2. Deep groove bearings 6-5 are installed inside the second mounting plates 6-2 on both sides, and the power roller 6-4 is installed in the deep groove bearings 6-5. They are then connected by the first synchronous pulley 6-9 and the first synchronous belt 6-10, and driven by the first servo motor 6-7 for transmission. The first servo motor 6-7 is mounted on the motor base 6-8, and the motor base 6-8 uses a waist-shaped mounting hole to adjust the tension of the first synchronous belt 6-10.

[0054] Please see Figure 9-11 In one embodiment, in order to punch the fabric, preferably, the punching mechanism 7 includes two movable components disposed on the frame 4 and a punching component disposed on the movable components, wherein a drive component for controlling the movement of the punching component is mounted on one of the movable components.

[0055] Please see Figure 9-11In one embodiment, preferably, the punching assembly includes a fourth mounting plate 7-2. A punching active cylinder 7-1 is mounted on the upper surface of the fourth mounting plate 7-2. Guide posts 7-3 are provided through the four corners of the upper end of the fourth mounting plate 7-2. The ends of the multiple guide posts 7-3 that penetrate the fourth mounting plate 7-2 are connected to the upper surface of the punching base plate 7-4. A floating joint 7-5 connected to the punching active cylinder 7-1 is mounted below the fourth mounting plate 7-2. A die-cutting slide plate 7-6 is provided between the fourth mounting plate 7-2 and the punching base plate 7-4. The die-cutting slide plate 7-6 is connected to the four guide posts 7-3 respectively through four second linear bearings 7-7. Two die-cutting mounting strips 7-8 are provided on the lower surface of the die-cutting slide plate 7-6 to limit the position of the laser die-cutting 7-9. A pair of die-cutting mounting strips 7-8 are mounted on the die-cutting slide plate 7-6 for the installation of the laser die-cutting 7-9 and to facilitate the replacement of dies of different specifications. The die-cutting mounting strips 7-8 are bolted to the die-cutting dies. The slide plate 7-6 is connected. Since a pair of die-cutting mounting strips 7-8 are located on both sides of the laser die-cutting die 7-9, the position of the laser die-cutting die 7-9 is fixed by fixing the position of the pair of die-cutting mounting strips 7-8. A punching bottom template 7-10 is installed on the upper surface of the punching bottom plate 7-4. The material of the punching bottom template 7-10 is not limited. In this embodiment, the punching bottom template 7-10 is made of alloy steel with a hardness of HRC or higher, and a silicone plate 7- is installed on the lower surface of the punching bottom template 7-10. 11. Four fourth compression springs 7-12 are evenly distributed on the lower surface of the punching bottom template 7-10, which are connected to the silicone plate 7-11 and the punching bottom plate 7-4. The ends of the four guide posts 7-3 are fitted with washers 7-13 and studs 7-14 for fixing the position of the washers 7-13. The upper surface of the fourth mounting plate 7-2 is provided with a lifting rod bolt 7-15 that is connected to the die-cutting slide plate 7-6. The outer circumferential surface of the lifting rod bolt 7-15 is threaded with an interlocking nut 7-16 for positioning it.

[0056] Specifically, the punching power is provided by the punching active cylinder 7-1. The fourth mounting plate 7-2 is installed in conjunction with the four guide pillars 7-3. Because the end faces of the guide pillars 7-3 are stepped, they can effectively position and install the punching base plate 7-4 and the fourth mounting plate 7-2, while also providing support. After installation, the studs 7-14 and washers 7-13 are connected. The end of the floating joint 7-5 away from the punching active cylinder 7-1 is connected to the die-cutting slide plate 7-6, so that the punching active cylinder 7-1 drives the die-cutting slide plate 7-6 to move up and down. The die-cutting slide plate 7-6 is equipped with a second linear bearing 7-7, which works in conjunction with the guide pillars 7-3. Meanwhile, the floating joint 7-5 can fine-tune the die-cutting plate 7-6. The hanger bolt 7-15 passes through the fourth mounting plate 7-2 and is installed on the die-cutting plate 7-6, and is then positioned by the interlock nut 7-16. The main function of this mechanism is to adjust and position the die-cutting mold to avoid overcutting and damaging the blade. The punching bottom template 7-10 is used in conjunction with the silicone plate 7-11. The silicone plate 7-11 and the four evenly distributed fourth compression springs 7-12 act as a buffer for the punching bottom template 7-10 to avoid hard impacts that could damage the blade. In this way, when the laser die-cutting mold 7-9 comes into contact with the punching bottom template 7-10, it can both break the product and extend the service life of the mold.

[0057] Please see Figure 9-11 In one embodiment, in order to move back and forth to process holes of different sizes at different positions, preferably, the moving component includes a third fixed plate 7-17 and a punching fixing seat 7-18 disposed on the lower end face of the third fixed plate 7-17. The punching fixing seat 7-18 is mounted on the upper surface of the frame 4. A linear slide rail 7-19 is mounted on the upper end of the third fixed plate 7-17 to limit the moving direction and distance of the punching base plate 7-4. The driving component includes a ball screw module 7-20 mounted on the upper end of the third fixed plate 7-17. The outer peripheral surface of the ball screw module 7-20 is provided with a ball screw connecting seat 7-21 connected to the punching base plate 7-4. A second servo motor 7-23 is mounted on the upper end of the third fixed plate 7-17. The second servo motor 7-23 and the ball screw module 7-20 are connected by a second coupling 7-22.

[0058] Specifically, the punching base plate 7-4 and the linear guide rail 7-19 are installed on the third fixed plate 7-17. The ball screw module 7-20 is installed on the third fixed plate 7-17 and connected to the punching base plate 7-4 by the ball screw connecting seat 7-21. The second servo motor 7-23 is connected to the ball screw by the second coupling 7-22. When holes at different positions are needed, the second servo motor 7-23 drives the ball screw to move the punching base plate 7-4 back and forth to process holes of different sizes, thereby achieving the purpose of automatic positioning punching production.

[0059] Please see Figure 12-13In one embodiment, for centralized discharge of waste, preferably, the waste removal mechanism 9 includes a waste suction base plate 9-1 and a slide rail assembly 9-2 disposed on the lower end face of the waste suction base plate 9-1 and connected to the frame 4. Two aluminum profile columns 9-3 are vertically mounted on the upper end of the waste suction base plate 9-1, and the ends of both aluminum profile columns 9-3 are connected to the lower end face of the fifth mounting plate 9-4. A cylinder 9-5 is mounted on the upper end of the fifth mounting plate 9-4, and a waste suction pressure plate 9-6 connected to the cylinder 9-5 is mounted below the fifth mounting plate 9-4. A waste suction base plate 9-6 is vertically mounted on the upper end of the waste suction base plate 9-1. Waste motor base 9-7, a third servo motor 9-8 is mounted on the side of the waste suction motor base 9-7, the output end of the third servo motor 9-8 passes through the waste suction motor base 9-7 and is equipped with a third coupling 9-9, two waste suction shaft seats 9-10 are mounted on the upper end of the waste suction base plate 9-1, a waste suction shaft 9-11 connected by the third coupling 9-9 is installed between the two waste suction shaft seats 9-10, a vacuum suction cup 9-12 is installed on the outer circumference of the waste suction shaft 9-11, and a pneumatic rotary joint 9-13 is installed at the end of the waste suction shaft 9-11 away from the third coupling 9-9 to facilitate free rotation when connecting to a vacuum pipe.

[0060] Specifically, cylinder 9-5 is mounted on the fifth mounting plate 9-4, which is mounted on the aluminum profile columns 9-3 on both sides. The aluminum profile columns 9-3 are mounted together with the waste suction base plate 9-1 to form a frame structure. The waste suction base plate 9-1 is mounted on the slide rail assembly 9-2 for position adjustment. This design allows for positional movement of the waste suction function for openings of different sizes. The waste suction pressure plate 9-6 is connected to cylinder 9-5. When the opening reaches this position, cylinder 9-5 presses down, causing the waste suction pressure plate 9-6 to press down the double-sided adhesive waste (because it is double-sided adhesive, it may stick during the previous punching and cutting process; pressing down the waste greatly ensures the waste removal effect and significantly reduces the defect rate). When the waste suction pressure plate 9-6 presses down the waste, the vacuum suction cup 9-12 starts working, firmly holding the waste. The waste suction pressure plate 9-6 returns and sends a signal to the third servo motor 9-8. The servo motor 9-8 is mounted on the waste suction motor base 9-7. At this time, the third servo motor 9-8 is connected to the third coupling 9-9 to drive the waste suction shaft 9-11 to start rotating. The vacuum suction cup 9-12 is mounted on the waste suction shaft 9-11 and starts to rotate downwards with the waste. When it rotates to 90°, the vacuum suction cup 9-12 moves again to automatically drop the waste into the waste removal hopper 12. The ball bearing mounted on the right side of the waste suction shaft 9-11 in the waste suction shaft base 9-10 enables free rotation. The pneumatic rotary joint 9-13 is mounted on the left side of the waste suction shaft 9-11 and is installed together with the rotary air joint support plate for easy installation. It can rotate freely when connected to the vacuum pipe. The entire vacuum mechanism is mounted on the waste suction base plate 9-1 and can move freely according to the different sizes of products (the waste suction position is based on the product. The punching position is automatically adjusted by the motor. When the punching position changes, the waste suction position must also change accordingly. At this time, the waste suction accuracy requirement is not so high, and manual forward and backward adjustment is sufficient).

[0061] Please see Figure 14-20In one embodiment, preferably, the fixed-length cross-cutting mechanism 11 includes a sixth mounting plate 11-1 and a seventh mounting plate 11-3 disposed on the upper end of the frame 4. Two fixed-length pressure roller mounting side plates 11-2 are mounted on the upper end of the sixth mounting plate 11-1, and two cross-cutting side plates 11-4 are mounted on the upper end of the seventh mounting plate 11-3. The sidewalls of both fixed-length pressure roller mounting side plates 11-2 are connected to transition guide rollers 11-5. A fixed-length power roller 11-6 and a fixed-length pressure roller 11-7 are provided between the two fixed-length pressure roller mounting side plates 11-2 for cooperative use. A first metal pair roller 11-9 is provided between the two cross-cutting side plates 11-4. Annular springs 11-8 are fitted onto the outer circumferential surfaces of the second metal roller 11-10, the fixed-length pressure roller 11-7, and the fixed-length power roller 11-6. The annular spring 11-8 on the fixed-length pressure roller 11-7 is connected to the first metal roller 11-9, and the annular spring 11-8 on the fixed-length power roller 11-6 is connected to the second metal roller 11-10. A bottom knife assembly 11-11, an upper cutting knife positioning block 11-12, a cross-cutting knife 11-13, and a cross-cutting adjusting strip 11-14 are respectively installed between the two cross-cutting side plates 11-4. Two connecting rods 11-15 are installed on the side wall of the cross-cutting adjusting strip 11-14. A linkage shaft 11-18 is installed between the two cross-sections 11-4. An eccentric bearing assembly 11-17, connected to the two connecting rods 11-15, is fixedly sleeved on the outer circumference of the linkage shaft 11-18. A second synchronous pulley 11-19 is installed at the end of the linkage shaft 11-18 extending to the outer side of the cross-section side plate 11-4. A fourth servo motor 11-21 is installed on the side wall of the cross-section side plate 11-4. The fourth servo motor 11-21 is connected to the second synchronous pulley 11-19 via a second synchronous belt 11-20. A clamping adjustment seat 11-23 is installed between the two cross-section side plates 11-4. A clamping adjustment seat 11-23 is provided between the clamping adjustment seat 11-23 and the cross-section cutter 11-13. There is a wear-resistant copper strip 11-22, and multiple adjusting bolts 11-24 for controlling the position of the wear-resistant copper strip 11-22 are installed on the clamping adjustment seat 11-23. A fifth servo motor 11-26 is installed on the side wall of the fixed length pressure roller mounting side plate 11-2. The fifth servo motor 11-26 and the fixed length power roller 11-6 are connected by a third synchronous belt 11-25. A receiving sheet metal 11-27 is installed on the side wall of the bottom knife assembly 11-11. The lower end face of the receiving sheet metal 11-27 is connected to the second bracket 11-29 through the first bracket 11-28. The end of the second bracket 11-29 is connected to the cross-cutting side plate 11-4.

[0062] Specifically, the fixed-length pressure roller mounting side plate 11-2 is installed on the same side plate as the sixth mounting plate 11-1 to ensure the force-bearing point. The sixth mounting plate 11-1 and the seventh mounting plate 11-3 have the same function, both connecting to the upper side plate and serving as mounting and fixing. Here, the fixed-length power roller 11-6 and the fixed-length pressure roller 11-7 have the same working principle and structure. Figure 3The intermediate power roller and pressure roller are basically the same, mainly feeding the rubber material to a fixed length to ensure that the cutting size meets the product process. However, the structure of the fixed-length power roller 11-6 and fixed-length pressure roller 11-7 is slightly different from the previous ones. Although they are both rubber-coated rollers, both rollers have evenly distributed staggered circumferential grooves, and specially customized annular springs 11-8 are installed in the grooves. The annular springs 11-8 are then connected to the first metal roller pair 11-9 and the second metal roller pair 11-10, respectively. This structure ensures that the roll material can be smoothly conveyed to the bottom knife assembly 1 when it passes through. At the cutting station 1-11, the bottom blade assembly 11-11 is installed inside the cross-cutting side plate 11-4 and is positioned by a locating pin to ensure the installation dimensions. The upper blade locating block 11-12 is installed inside the cross-cutting side plate 11-4 to position the cross-cutting blade 11-13. The eccentric bearing assembly 11-17 is connected to the connecting rod 11-15 by a pin 11-16. Two eccentric bearing assemblies 11-17 are installed on the outer circumference of the linkage shaft 11-18. The linkage shaft 11-18 is equipped with a second synchronous pulley 11-19 that connects to the second synchronous belt 11-2. 0, and the fourth servo motor 11-21 drives the linkage shaft 11-18 to rotate via the second synchronous belt 11-20 and the second synchronous pulley 11-19. This causes the eccentric bearing assembly 11-17 to pull the connecting rod 11-15, thereby causing the cross-cutting blade 11-13 to reciprocate up and down. This allows the cross-cutting blade 11-13 to contact the bottom blade assembly 11-11 and generate a shearing action, achieving the function of cutting the product. The wear-resistant copper strip 11-22 and the clamping adjustment seat 11-23 are respectively installed at the ends of the two cross-cutting side plates 11-4. Adjusting bolt 11-24 is installed on clamping adjustment seat 11-23 to apply pressure to wear-resistant copper strip 11-22 to ensure the pre-tightening force of cross-cutting blade 11-13 and bottom blade assembly 11-11. The third synchronous belt 11-25 is powered by the fifth servo motor 11-26 to drive the fixed-length power roller 11-6 to perform fixed-length feeding action. When the product is fed in until it is cut, it will fall to the receiving sheet metal 11-27. The receiving sheet metal 11-27 is supported and its angle is adjusted by the second bracket 11-29 so that the product can slide freely to the receiving point.

[0063] The surface of the fixed-length pressure roller mounting side plate 11-2 is equipped with a second pressing block assembly 11-30, and the surface of the transverse side plate 11-4 is equipped with a third pressing block assembly 11-31. The structural principle of the second pressing block assembly 11-30 and the third pressing block assembly 11-31 is the same as that of the first pressing block assembly, which is to lift the linkage rod and use the spring force to apply pre-tightening force. The adjustment assembly 11-32 installed on the side wall of the transverse side plate 11-4 can play an overall adjustment role for the third pressing block assembly 11-31.

[0064] Specifically, the upper end of the adjusting component 11-32 is connected to the lower end of the third pressing block component 11-31. The adjusting component 11-32 includes an adjusting block and a threaded rod. By rotating the threaded rod clockwise or counterclockwise, the upper end of the threaded rod can be raised or lowered, which can make overall fine adjustments to the height of the third pressing block component 11-31.

[0065] Please see Figure 21 In one embodiment, for cutting the fabric, preferably, the bottom blade assembly 11-11 includes a bottom blade fixing seat 11-11-1 connected to the cross-cutting side plate 11-4, a bottom blade 11-11-2 and an eighth mounting plate 11-11-3 disposed on the upper end of the bottom blade fixing seat 11-11-1, wherein the flatness and parallelism of the eighth mounting plate 11-11-3 and the bottom blade fixing seat 11-11-1 are both 0.01mm; a spacing is left between the mounting holes. The locating pin ensures dimensional accuracy. The other row of threaded holes is for fine-tuning the vertical dimensions of the bottom blade 11-11-2. The holes of the bottom blade 11-11-2 when it is installed on the eighth mounting plate 11-11-3 are oblong holes to facilitate the vertical dimension fine-tuning. The other row of threaded holes is for fine-tuning the front and rear dimensions of the bottom blade 11-11-2. Finally, the bottom blade 11-11-2 will work together with the cross-cutting blade 11-13 to generate shearing force, thereby cutting the double-sided tape.

[0066] Please see Figure 22-23 In one embodiment, preferably, the eccentric bearing assembly 11-17 includes an eccentric bearing sleeve 11-17-1 connected to the connecting rod 11-15, an eccentric bearing 11-17-2 is installed at the end of the eccentric bearing sleeve 11-17-1, an eccentric flange cover 11-17-3 is installed on the side of the eccentric bearing 11-17-2, and an eccentric flange 11-17-4 is provided on the side of the eccentric bearing 11-17-2 away from the eccentric flange cover 11-17-3. The eccentric flange 11-17-4 and the eccentric flange cover 11-17-3 are connected by bolts, and the eccentric flange cover 11-17-3 is finally installed on the surface to ensure the sealing of the eccentric bearing 11-17-2.

[0067] The working principle and usage process of this invention are as follows: First, after the roll material passes through the air expansion shaft 2-2, it is installed on the unloading mechanism 2. The punching and feeding mechanism 6 drives the material forward. At this time, to ensure a uniform and smooth forward feeding, the magnetic powder brake in the unloading mechanism 2 works simultaneously, applying a certain torque to the roll material so that it can move forward smoothly and uniformly. At this time, the fabric arrives at the automatic correction mechanism 3, which uses the sensing point of fabric deviation to swing left and right to achieve the correction function. When the corrected fabric passes through the transition buffer mechanism 5 and is pulled by the punching and feeding mechanism 6 to the punching mechanism 7, it will pause for the first time. Then, the punching active cylinder 7-1 in the punching mechanism 7 drives the die slide 7-6 to move. At the same time, the laser die 7-9 moves together and contacts the punching bottom template 7-10. The punching pressure generated punches the fabric at the top with the required holes. When the action ends, the fabric moves forward. At this time, the movement is pulled forward by the fixed length feeding rollers in the fixed length cross-cutting. At this time, when there is punching waste material... When the material reaches station 9 of the waste removal mechanism, its waste is sucked out and sent to the waste removal hopper 12, which is dedicated to collecting waste. The specific mechanism operation is described in detail above. All the action rhythms are synchronized with the punching rhythm. At this time, the perforated material arrives at the fixed-length cross-cutting mechanism 11. It is conveyed forward to a fixed length by the fixed-length pressure roller (11-7) and the fixed-length power roller (11-6). The annular spring (11-8) plays a role in transmission and clamping, and smoothly delivers the material to the cross-cutting point. The eccentric bearing assembly (11-1) 7) The rotating mechanism drives the connecting rod (11-15) to connect to the cross-cutting blade (11-13) to perform up-and-down reciprocating motion, thereby tangenting with the bottom blade 11-11-2 and generating shearing force to neatly cut the material. The finished product falls onto the receiving sheet metal 11-27 for workers to collect. (This description applies to various product specifications. When different sizes are present, the second servo motor 7-23 drives the ball screw module 7-20 to move the punching base plate 7-4 back and forth to adjust the different hole positions and sizes.)

[0068] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0069] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
