Description

Technical Field

[0001] This invention relates to the field of perforation technology, specifically to a perforation equipment and method. Background Technology

[0002] In the production and processing of yoga mats, the perforation process is usually a key post-processing step, which is directly related to the functionality, aesthetics, and user experience of the product. This step is not a necessary process for all yoga mats, but is for products with specific design or functional requirements. That is, some yoga mats have a round or oval perforation designed on one or both sides. This hole allows users to use yoga mat straps or directly thread ropes to roll up the mat and hang it for storage, saving storage space and maintaining the rolled shape of the mat, avoiding permanent creases caused by long-term folding. Or, for interlocking yoga mats used for pair practice or special scenarios, matching holes may be designed on the edge so that multiple mats can be connected together by buttons, plugs, or ropes.

[0003] The forming of this type of perforation is currently widely accomplished using cold stamping dies. Its core consists of two parts: a punch and a die. When the die is working, the punch moves downwards at high speed under the drive of the press, creating a shearing action with the die fixed on the lower die base. The yoga mat material (usually TPE, PVC, or natural rubber) is placed between them. Under the strong pressure of the punch, the material first undergoes elastic deformation, then enters the plastic deformation stage. Finally, under the shearing action of the punch's cutting edge and the die's edge, the internal fibers of the material are neatly cut, forming a smooth, circular hole. In specific operation, a flat yoga mat is fed to the die positioning baffle and placed into the die of the lower die base, ensuring that the edges of the mat are aligned with the die. The positioning reference is perfectly aligned, but this process is limited by the overall size of the yoga mat, which is usually 163-200cm in length, 60-80cm in width, and has an area of ​​about 1-1.5 square meters. This requires a large operating space, and the leveling, loading, and unloading operations are relatively inconvenient. It is difficult to perfectly and smoothly align it with the positioning surface of the mold in a short time. Furthermore, it is also troublesome to change or modify the end hole positions according to different sizes of yoga mats. It requires replacing the entire set of punches and dies, which involves lifting and unloading molds weighing hundreds of kilograms, cleaning the workbench, installing new molds and readjusting and centering, connecting auxiliary devices, and resetting the press stroke and pressure parameters. This makes it difficult to quickly adapt to the market trend of small batches and multiple varieties. Summary of the Invention

[0004] The purpose of this invention is to provide a perforation processing device and method. A yoga mat is placed on a roller conveyor line. The yoga mat is moved by the roller pressing and leveling assembly and the roller conveyor line until the yoga mat hangs down naturally along the bend of the side plate and is located on one side of the double hole forming assembly. After the lower end of the yoga mat moves to the perforation position, the roller conveyor line stops and the yoga mat is limited by the pressing assembly. The double hole forming assembly is adjusted according to the distance between the two hole positions. After adjustment and shaping, the double hole forming assembly is driven by the servo feed assembly to move towards the yoga mat, and the double hole forming assembly makes perforations on the yoga mat, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a perforation processing device, comprising an outer frame, a roller conveyor line installed inside the upper part of the outer frame for horizontally conveying yoga mats, and a roller pressing and leveling assembly installed at the top of the outer frame for applying a vertical load to the yoga mats on the roller conveyor line. A side plate is bolted to one side of the outer wall of the outer frame, and the upper end of the side plate is integrally formed with a bend. The bend is used to connect with the end of the roller conveyor line and guide the yoga mat from horizontal movement to a vertical hanging state. A side frame is fixed to the side of the side plate away from the outer frame, and a servo feed assembly is installed on one side of the side frame. A double-hole forming assembly that can adjust the linear distance between two hole positions is installed at the drive end of the servo feed assembly. A control box that is electrically connected to the input end of the roller conveyor line, the roller pressing and leveling assembly, the pad assembly, the servo feed assembly, and the double-hole forming assembly is installed on one side of the outer wall of the side plate.

[0006] Preferably, the roller pressing and leveling assembly includes a hanging frame disposed above the roller conveyor line, a first hydraulic cylinder installed on the top of the outer frame and controlling the height of the hanging frame, and a number of pressure rollers that are rotatably installed side by side at equal intervals inside the hanging frame. Guide posts that extend upward through to the outside of the outer frame are fixed at the corners of the top of the hanging frame.

[0007] Preferably, the pressure pad assembly includes a second hydraulic cylinder installed at the left and right positions of the top of the lifting frame and a pressure plate fixedly installed at the bottom of the piston rod of the second hydraulic cylinder. Guide rods extending upward through the outside of the lifting frame are also fixed on both sides of the top of the pressure plate.

[0008] Preferably, the servo feed assembly includes an inner U-shaped frame mounted on the outer wall of one side of the side frame, a servo electric cylinder fixedly mounted inside the inner U-shaped frame, and an outer U-shaped frame fixedly mounted at the end of the piston rod of the servo electric cylinder. Piezoelectric sensors are installed at the corners of the outer wall of the outer U-shaped frame away from the side frame, and a connecting plate is installed at the end of the piezoelectric sensor away from the outer U-shaped frame.

[0009] Preferably, four horizontal columns are installed on the outer wall of the side plate away from the outer frame, and a sliding table is slidably installed on the four horizontal columns. The outer wall of one side of the sliding table is fixedly connected to the outer U-shaped frame.

[0010] Preferably, a hollow section is provided at the center of the slide, and the inner U-shaped frame is located in the hollow section.

[0011] Preferably, the dual-hole forming assembly includes a long U-shaped arm fixed to the outer wall of one side of the connecting plate and a servo bidirectional lead screw module installed at the top of the long U-shaped arm along the length direction. A motor is installed on both drive ends of the servo bidirectional lead screw module, and a punching tool is detachably installed at the output shaft end of the motor.

[0012] Preferably, two straight slots are provided on one outer wall of the side plate, through which the punch and the output shaft of the motor pass.

[0013] Preferably, the length of the straight slot is parallel to the driving direction of the servo bidirectional lead screw module, and the width of the straight slot is greater than the outer diameter of the punch.

[0014] The present invention also provides a method for perforation processing, using the perforation processing equipment described above, comprising the following steps:

[0015] S101: The yoga mat is placed on a roller conveyor line running at a constant speed. The roller conveyor line carries the yoga mat forward smoothly and passes through the roller pressing and leveling assembly. The roller pressing and leveling assembly applies pressure evenly to the yoga mat to eliminate internal stress, natural warping or slight wrinkles caused by the mat being rolled up during storage. After being leveled, the yoga mat continues to move forward with the roller conveyor line until its front end reaches and contacts the side plate installed at the end of the roller conveyor line. Under the continuous action of the conveying power, the front end of the yoga mat will smoothly transition from horizontal conveying to a downward natural hanging posture along the bend on the side plate.

[0016] S102: When the lower edge of the yoga mat has moved to the preset precise punching position, the control box issues a command, the roller conveyor line stops accurately, and at the same time the pad assembly presses down quickly from above to firmly press and fix the yoga mat.

[0017] S103: The double-hole forming assembly is adjusted according to the hole spacing required by the current product, and the servo feed assembly drives the entire double-hole forming assembly to move smoothly toward the hanging part of the yoga mat. During the movement, the double-hole forming assembly punches out two perforations that meet the design requirements on the yoga mat at one time.

[0018] S104: After the stamping is completed, the servo feed assembly immediately resets, driving the double hole forming assembly back to its original position, and the pressure pad assembly also releases and resets. Finally, the roller conveyor restarts, conveying or unloading the perforated yoga mat downstream.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: The perforation processing equipment and method, through a structure comprising a roller conveyor line, a roller leveling assembly, a side plate, a bend, a pressure pad assembly, a side frame, a servo feed assembly, and a double-hole forming assembly, utilizes the roller leveling assembly and the roller conveyor line to assist the yoga mat in moving until the yoga mat naturally hangs down along the bend of the side plate and is located on one side of the double-hole forming assembly. After the lower end of the yoga mat moves to the perforation position, the roller conveyor line stops, and the pressure pad assembly limits the yoga mat. The hole forming assembly is adjusted according to the distance between the two hole positions. After adjustment and confirmation, the servo feed assembly drives the double hole forming assembly to move towards the yoga mat. The double hole forming assembly makes perforations on the yoga mat, thereby integrating the discrete leveling, conveying, positioning and stamping actions. The action sequence and process parameters of each actuator are controlled by the control box, so that the cycle time in large-scale production can be precise and the hole position distance and stamping depth parameters can be adjusted quickly, realizing flexible production of small batches and multiple varieties of yoga mat perforations.

[0020] In traditional methods, operators need to manually flatten and position the flexible and easily wrinkled yoga mat, which is time-consuming, labor-intensive, and yields inconsistent results. In this solution, the yoga mat is continuously rolled during the conveying process, allowing it to unfold evenly and flatly, reducing wrinkles or positioning deviations caused by human factors. The continuous movement of the conveyor line also makes the feeding process smooth, eliminating the need for repeated manual handling and adjustment. Secondly, the dual-hole forming assembly can quickly adjust the hole spacing according to different products. Combined with the servo feed assembly, it drives the punching unit to move smoothly, ensuring that the hole position of each punch is absolutely accurate and consistent, eliminating the dimensional errors that may be caused by manual positioning. Moreover, dual-hole processing can be completed in one action, which is more efficient than traditional single punching or multiple positioning operations. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Example 1, by Figures 1 to 4 The present invention includes an outer frame 1, a roller conveyor 2 installed inside the upper part of the outer frame 1 for horizontally conveying yoga mats, and a roller pressing and leveling assembly 3 installed at the top of the outer frame 1 for applying a vertical load to the yoga mats on the roller conveyor 2. A side plate 5 is bolted to one side of the outer wall of the outer frame 1. The upper end of the side plate 5 is integrally formed with a bend 501, which is used to connect with the end of the roller conveyor 2 and guide the yoga mats to naturally transition from horizontal movement to a vertical hanging state. A side frame 6 is fixedly connected to the side of the side plate 5 away from the outer frame 1, and a servo feed assembly 7 is installed on one side of the outer wall of the side frame 6. A double hole forming assembly 8 that can adjust the linear distance between two holes is installed at the drive end of the servo feed assembly 7. A control box 9 is installed on one side of the outer wall of the side plate 5 and is electrically connected to the input ends of the roller conveyor 2, the roller pressing and leveling assembly 3, the pad assembly 4, the servo feed assembly 7, and the double hole forming assembly 8.

[0033] The control box 9 uses a built-in programmable logic controller to convert the operator's production instructions, such as product model and hole spacing parameters, into a precise sequence of actions that the machine can execute. The operator does not need to manually adjust the mechanical parts based on experience; they can simply select or input parameters on the touch screen.

[0034] Roller conveyor 2 provides a continuous and stable material transfer foundation, and roller conveyor 2 can also be replaced by belt conveyor.

[0035] This embodiment of a perforation processing method, using the above-mentioned perforation processing equipment, includes the following steps:

[0036] S101: The yoga mat is placed on the roller conveyor 2 running at a uniform speed. The roller conveyor 2 carries the yoga mat forward smoothly and passes through the roller pressing and leveling assembly 3. The roller pressing and leveling assembly 3 applies pressure evenly to the yoga mat to eliminate the internal stress, natural warping or slight wrinkles caused by the mat being rolled up during storage. After being leveled, the yoga mat continues to move forward with the roller conveyor 2 until its front end reaches and contacts the side plate 5 installed at the end of the roller conveyor 2. Under the continuous action of the conveying power, the front end of the yoga mat will smoothly transition from horizontal conveying to a downward natural hanging posture along the bend 501 on the side plate 5.

[0037] S102: When the lower edge of the yoga mat has moved to the preset precise punching position, the control box 9 issues a command, the roller conveyor 2 stops accurately, and at the same time the pad assembly 4 presses down quickly from above to firmly press and fix the yoga mat.

[0038] S103: The double hole forming assembly 8 is adjusted according to the hole spacing required by the current product, and the servo feed assembly 7 drives the entire double hole forming assembly 8 to move smoothly toward the hanging part of the yoga mat. During the movement, the double hole forming assembly 8 punches out two perforations that meet the design requirements on the yoga mat at one time.

[0039] S104: After the stamping is completed, the servo feed assembly 7 immediately resets, driving the double hole forming assembly 8 back to its original position, and the pressure pad assembly 4 also releases and resets. Finally, the roller conveyor line 2 restarts, conveying or unloading the perforated yoga mat downstream.

[0040] Example 2, based on Example 1, is... Figure 5 and Figure 6The roller leveling assembly 3 includes a hanging frame 301 set above the roller conveyor line 2, a first hydraulic cylinder 302 installed on the top of the outer frame 1 and controlling the height of the hanging frame 301, and several pressure rollers 303 that are rotatably installed side by side at equal intervals inside the hanging frame 301. Guide posts 304 that extend upward to the outside of the outer frame 1 are fixed at the corners of the top of the hanging frame 301. According to the thickness specifications of the yoga mat, the first hydraulic cylinder 302 is controlled by the control box 9 to work. The first hydraulic cylinder 302 drives the hanging frame 301 and each pressure roller 303 to move down together. The pressure rollers 303 contact the yoga mat, thereby leveling the yoga mat during the conveying process, reducing warping, wrinkles and internal stress caused by curling or material characteristics of the mat, so that it reaches a flat and uniform state before punching.

[0041] The pressure pad assembly 4 includes a second hydraulic cylinder 401 installed at the top left and right positions of the lifting frame 301, and a pressure plate 403 fixedly installed at the bottom end of the piston rod of the second hydraulic cylinder 401. Guide rods 402 extending upward to the outside of the lifting frame 301 are also fixed on both sides of the top of the pressure plate 403. When performing the piercing operation, the second hydraulic cylinder 401 drives the pressure plate 403 and the guide rods 402 to move downward, and uses the pressure plate 403 to press the yoga mat on the roller conveyor line 2 to eliminate the slippage, vibration or elastic deformation that may occur in the flexible material during the punching moment, and ensure the accuracy of the punching position and the integrity and clarity of the hole edge shape.

[0042] Example 3, based on Example 2, by Figure 7 , Figure 8 and Figure 9 As shown, the servo feed assembly 7 includes an inner U-shaped frame 701 mounted on the outer wall of one side of the side frame 6, a servo electric cylinder 702 fixedly mounted inside the inner U-shaped frame 701, and an outer U-shaped frame 704 fixedly mounted on the piston rod end of the servo electric cylinder 702. Piezoelectric sensors 705 are installed at the corners of the outer wall of the outer U-shaped frame 704 away from the side frame 6, and a connecting plate 706 is installed at the end of the piezoelectric sensor 705 away from the outer U-shaped frame 704.

[0043] Four horizontal columns 601 are installed on the outer wall of the side plate 5 away from the outer frame 1. A slide table 703 is slidably installed on the four horizontal columns 601. One side of the outer wall of the slide table 703 is fixedly connected to the outer U-shaped frame 704. A hollow part 7031 is provided at the center of the slide table 703. The inner U-shaped frame 701 is located in the hollow part 7031. After the double hole forming assembly 8 is debugged, the servo cylinder 702 moves according to the command of the control box 9. During this process, the servo cylinder 702 pushes the slide table 703, the outer U-shaped frame 704, the piezoelectric sensor 705, the connecting plate 706 and the double hole forming assembly 8 toward the yoga mat until the double hole forming assembly 8 passes through. During this process, the horizontal column 601 serves as a rigid guide for the slide table 703 and the sub-components.

[0044] The dual-hole forming assembly 8 includes a long U-shaped arm 801 fixed to the outer wall of one side of the connecting plate 706 and a servo bidirectional lead screw module 802 installed at the top of the long U-shaped arm 801 along the length direction. Motors 803 are installed on both drive ends of the servo bidirectional lead screw module 802. A punching tool 804 is detachably installed at the output shaft end of the motor 803. Two straight slots 502 are provided on one side of the outer wall of the side plate 5. The straight slots 502 allow the punching tool 804 and the output shaft of the motor 803 to pass through.

[0045] The length of the straight slot 502 is parallel to the driving direction of the servo bidirectional lead screw module 802, and the width of the straight slot 502 is greater than the outer diameter of the punch 804. The servo bidirectional lead screw module 802 drives two motors 803 to move towards each other in the length direction of the long U-shaped arm 801 to change the distance between the two punches 804. When the servo feed assembly 7 pushes the double hole forming assembly 8 close to the side plate 5, the motor 803 drives the punch 804 to rotate until the punch 804 makes a hole on the yoga mat and passes through the straight slot 502, so as to process two holes with the hole spacing meeting the design requirements at one time and simultaneously on a yoga mat.

[0046] The dual-hole forming assembly 8 can adjust the distance between the two punching blades 804 according to different product parameters issued by the control box 9, thus solving the problem of troublesome changeover in traditional production.

[0047] In this embodiment, the specifications of the yoga mat to be processed are first selected on the human-machine interface of the control box 9 to set the feeding speed of the roller conveyor 2, the roller pressure of the roller leveling assembly 3, the target hole spacing of the double hole forming assembly 8, and the feed parameters of the servo feed assembly 7. The yoga mat is manually placed on the roller conveyor 2 running at a uniform speed. The roller conveyor 2 carries the yoga mat forward smoothly and passes through the roller leveling assembly 3. The roller leveling assembly 3 applies pressure evenly to the yoga mat to eliminate internal stress, natural warping, or slight wrinkles caused by the mat being rolled up during storage, making it extremely flat and of uniform thickness before entering the subsequent workstation. The flattened yoga mat continues to move forward with the roller conveyor 2 until its front end reaches and contacts the side plate 5 installed at the end of the roller conveyor 2. Under the continuous action of the conveying power, the front end of the yoga mat will smoothly transition from horizontal conveying to a downward naturally hanging posture along the bend 501 on the side plate 5. The yoga mat is suspended in a waiting area on one side of the double-hole forming assembly 8. When the lower edge of the yoga mat has moved to the preset precise punching position, the control box 9 issues a command, the roller conveyor 2 stops accurately, and the pressure pad assembly 4 presses down quickly from above to firmly press and fix the yoga mat, preventing the material from sliding, rebounding or deforming during the punching process, and ensuring the absolute positional accuracy of the punching and the clear and neat edge of the hole. The double-hole forming assembly 8 can be adjusted according to the hole spacing required by the current product, and the servo feed assembly 7 drives the entire double-hole forming assembly 8 to move smoothly toward the suspended part of the yoga mat. During the movement, the double-hole forming assembly 8 punches two holes that meet the design requirements on the yoga mat at one time. After the punching is completed, the servo feed assembly 7 immediately resets, driving the double-hole forming assembly 8 back to its original position, and the pressure pad assembly 4 also releases and resets. Finally, the roller conveyor 2 restarts, conveying or unloading the perforated yoga mat downstream.
