Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to an ultrasonic punching machine. Background Technology

[0002] A fabric cutting machine is a machine used to cut fabric into samples or products of the required specifications for mass production. The traditional working principle of a fabric cutting machine is to first transfer the fabric onto the machine, which then rotates the fabric and drives it to the cutting blade for cutting. The cut fabric is then collected. However, existing fabric cutting machines have relatively poor precision. During the actual cutting process, due to the elasticity of the fabric, especially smooth fabrics, problems such as slippage or wrinkling can easily occur, leading to poor cutting accuracy, low product yield, and numerous rough edges in the cut fabric segments, resulting in inconsistent product quality. Utility Model Content

[0003] This invention provides an ultrasonic punching and cutting machine, which solves the problems of poor cutting accuracy and reduced product quality in the above-mentioned technologies.

[0004] The technical solution is as follows:

[0005] An ultrasonic punching and cutting machine includes a fabric feeding mechanism for feeding fabric into a device, a fabric conveying mechanism for conveying fabric, and a cutter holder. The fabric conveying mechanism is located downstream of the fabric feeding mechanism, and the cutter holder is located at the output end of the device. It also includes a fabric pressing and cutting mechanism for pressing and cutting the fabric. The fabric pressing and cutting mechanism is located downstream of the fabric conveying mechanism and includes a fabric pressing mechanism for pressing the fabric and a fabric cutting mechanism for cutting the fabric. Both the fabric pressing mechanism and the fabric cutting mechanism are located above the cutter holder, and the distance between the fabric cutting mechanism and the cutter holder is greater than the distance between the fabric pressing mechanism and the cutter holder.

[0006] Furthermore, the fabric feeding mechanism includes a tensioning rod, a fixed seat, a guide rod, a mounting seat, a pressure plate, and a torsion spring. The tensioning rod is connected to the fixed seat, the mounting seat is connected to the guide rod, the pressure plate is hinged to the guide rod, one end of the torsion spring is connected to the pressure plate, and the other end of the torsion spring is connected to the guide rod.

[0007] Furthermore, the fabric conveying mechanism includes a guiding mechanism, a transmission mechanism, and a driving mechanism. The transmission mechanism is located downstream of the guiding mechanism, and the guiding mechanism and the transmission mechanism cooperate with each other. The transmission mechanism is connected to the driving mechanism.

[0008] Furthermore, the guiding mechanism includes a base, a support block, a support rod, and a limiting block. The base is connected to the transmission mechanism, the support block is connected to the base, and the limiting block cooperates with the base. The limiting block is provided with a through hole, and the support rod passes through the through hole on the limiting block and connects to the support block.

[0009] Furthermore, the transmission device includes a transmission block, a first rubber roller, and a second rubber roller. The transmission block is connected to the base, the first rubber roller and the second rubber roller cooperate, and one end of the first rubber roller and the second rubber roller are respectively connected to the drive mechanism.

[0010] Furthermore, the drive mechanism includes a gear, a pulley, a belt, a first drive component, a first rubber roller and a second rubber roller respectively connected to a gear, the second rubber roller is also connected to a pulley, the first drive component is connected to another pulley, and the belt and pulley are dynamically coordinated.

[0011] Furthermore, the fabric cutting mechanism includes a cutter, a connecting plate, a connecting rod, a cover plate, and a second driving component. The cutter is connected to the lower end of the connecting plate, and the cover plate is provided with a through hole. The connecting rod passes through the through hole in the cover plate and cooperates with the connecting plate. The second driving component is located on the cover plate, and a part of the second driving component passes through another through hole in the cover plate and is connected to the connecting plate.

[0012] Furthermore, the pressing mechanism includes a spring, a guide rod, a retaining ring, and a pressing block. The spring is sleeved on the guide rod and cooperates with the guide rod. The connecting plate has a through hole. The top of the guide rod passes through the through hole on the connecting plate and cooperates with the connecting plate. The part of the top of the guide rod that passes through the connecting plate is connected to the retaining ring. The pressing block is connected to the guide rod.

[0013] Furthermore, it also includes an ultrasonic heater, with a through hole on the knife holder, and the output end of the ultrasonic heater is matched with the through hole.

[0014] In this invention, the fabric feeding mechanism feeds the fabric onto the device, and the fabric conveying mechanism tensions the fabric and conducts it on the device. After the fabric is conducted to the fabric cutting and pressing mechanism, the second driving component in the fabric pressing and cutting mechanism drives the connecting plate to move downward along the guide rod. After the connecting plate moves downward until the pressure plate contacts the knife holder, the guide rod is stationary, causing the downward-moving connecting plate to compress the spring sleeved on the guide rod. When the spring is compressed to a certain extent, the spring further applies pressure to the pressure block, causing the pressure block to press down until the pressure block presses the fabric tightly. Since the distance between the pressure block and the knife holder is less than the distance between the cutter and the knife holder, the pressure block has already pressed the fabric before the cutter cuts it, avoiding problems such as side slippage and wrinkles during the cutting process. This has the advantages of improving cutting accuracy and product quality. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 4 This invention relates to an ultrasonic punching and cutting machine, comprising a fabric feeding mechanism for feeding fabric into a device, a fabric conveying mechanism for conveying fabric, and a cutter holder 1. The fabric conveying mechanism is located downstream of the fabric feeding mechanism, and the cutter holder 1 is also located downstream of the fabric conveying mechanism. The machine further includes a fabric pressing and cutting mechanism for pressing and cutting the fabric, located downstream of the fabric conveying mechanism. The fabric pressing and cutting mechanism includes a fabric pressing mechanism for pressing the fabric and a fabric cutting mechanism for cutting the fabric. Both the fabric pressing and cutting mechanisms are located above the cutter holder 1, and the distance between the cutting mechanism and the cutter holder 1 is greater than the distance between the fabric pressing mechanism and the cutter holder 1. Therefore, when the fabric pressing and cutting mechanism is working, the fabric pressing mechanism can press the fabric before the cutting mechanism acts. The fabric feeding mechanism, fabric conveying mechanism, and fabric pressing and cutting mechanism are mounted on a housing A, and an electrical box B is installed inside housing A, controlling the operation of the entire device.

[0024] The fabric feeding mechanism includes tension rods 2, fixed bases 3, guide rods 4, mounting bases 5, pressure plates 6, and torsion springs 7. The fixed bases 3 have multiple mounting holes, and the two ends of the multiple tension rods 2 are fixed to the fixed bases 3 respectively. After the fabric is fed in, the fabric passes through the multiple tension rods 2 in an S-shape. The mounting bases 5 have multiple mounting holes, and the two ends of the multiple guide rods 4 are fixed to the mounting bases 5. Similarly, the fabric passes through the multiple guide rods 4 in an S-shape. The pressure plate 6 is hinged to the guide rods 4. The middle of the pressure plate 6 has a toothed protrusion structure. One end of the torsion spring 7 is connected to the pressure plate 6, and the other end of the torsion spring 7 is connected to the guide rods 4.

[0025] The fabric conveying mechanism includes a guiding mechanism, a transmission mechanism, and a driving mechanism. The guiding mechanism and the transmission mechanism work together, and the transmission mechanism is connected to the driving mechanism.

[0026] The guiding mechanism includes a base 8, a support block 9, a support rod 10, and a limiting block 11. One side of the base 8 is provided with a toothed groove, which forms a concave-convex fit structure with the toothed protrusion on the pressure plate 6, facilitating the smoothing of the fabric during the fabric transfer process. The middle part of the base 8 has a hollow structure, which facilitates the installation and disassembly of the base 8. The base 8 is connected to the transfer mechanism. The support block 9 is connected to the upper end of the base 8. The limiting block 11 has a protrusion structure 11a, which cooperates with the groove 8a on the base 8, allowing the limiting block 11 to adjust its position along the groove 8a on the base 8, preventing the limiting block 11 from shifting during the adjustment process. Two limiting blocks 11 are symmetrically distributed on the long side of the base 8. The limiting block 11 is provided with a through hole, through which the support rod 10 passes and connects to the support block 9. The screw hole 11b on the limiting block 11 is interference-fitted with a screw. In this embodiment, the device can be adjusted according to the width of the fabric. For example, if the width needs to be adjusted, the protrusion 11a on the limiting block 11 can be moved along the groove 8a on the base 8, and the limiting block 11 can be moved along the support rod 10 to increase the distance between the two limiting blocks 11 until a width that matches the fabric is achieved.

[0027] The transmission mechanism includes a conveyor block 12, a first rubber roller 13, and a second rubber roller 14. The conveyor block 12 is connected to the base 8. The conveyor block 11 has a sloping structure. The first rubber roller 13 and the second rubber roller 14 cooperate with each other, and one end of the first rubber roller 13 and the second rubber roller 14 are respectively connected to the drive mechanism. During operation, the first rubber roller 13, the second rubber roller 14, the tensioning rod 2, and the guide rod 4 work together to tension the fabric.

[0028] The drive mechanism includes a gear 15, two pulleys 16, a belt 17, and a first drive component 18. One end of the first rubber roller 13 and the second rubber roller 14 are respectively connected to a gear 15, and the two gears 15 mesh with each other. One end of the second rubber roller 13 is also connected to the pulley 16. The first drive component 18 is connected to the other pulley 16. The two pulleys 16 are connected by a belt 17, and the belt 17 and the pulley 16 are dynamically engaged.

[0029] The fabric cutting mechanism includes a cutter 19, a connecting plate 20, a connecting rod 21, a cover plate 22, and a second driving component 23. The cutter 19 is connected to the lower end of the connecting plate 20. The cover plate 22 has a through hole, and the connecting rod 21 passes through the through hole in the cover plate 22 and is fixed to the connecting plate 20. The second driving component 23 is located on the cover plate 22, and a part of the second driving component 23 passes through another through hole in the cover plate 22 and is connected to the connecting plate 20. The first driving component 17 can be a cylinder or a hydraulic cylinder.

[0030] The pressing mechanism includes a spring 24, a guide rod 25, a retaining ring 26, and a pressing block 27. The spring 24 is sleeved on the guide rod 25 and cooperates with the guide rod 25. The connecting plate 20 is provided with a through hole. The tops of the two guide rods 25 pass through the through hole on the connecting plate 20 and slide in cooperation with the through hole. The part of the top of the guide rod 25 that passes through the connecting plate 20 is fixed with the retaining ring 26. The two ends of the pressing block 27 are respectively connected to one of the guide rods 25.

[0031] It also includes an ultrasonic heater 28, and the knife holder 1 has a through hole, the output end of the ultrasonic heater 28 is matched with the through hole.

[0032] The working process of this utility model is as follows:

[0033] The fabric is wound onto a take-up roller (not shown in the figure). After being released, the fabric passes through the tension rod 2 and the guide rod 4 in sequence, then passes between the pressure plate 6 and the base 8. The fabric then enters the fabric conveying mechanism. First, the first drive component 18 in the drive unit provides power, causing the first rubber roller 13 and the second rubber roller 14 to rotate, applying traction force to the fabric and moving it along the guide mechanism. The first drive component 18 continues to work until the fabric is conveyed to the pressing and cutting mechanism. When the length of the fabric passing through the cutter 1 reaches the set requirement, the conveying mechanism pauses, and the pressing and cutting mechanisms work. The fabric is laid flat on the cutter 1. At this time, the second drive component 23 drives the connecting plate 20 to move downward. When the connecting plate 20 moves downward, it drives the guide rod 25 downward. Move a distance until the pressure block 27 contacts the plate surface of the cutter holder 1. The fabric is pressed between the pressure block 27 and the cutter holder 1. The guide rod 25 stops moving. Then, the connecting plate 20 begins to compress the spring 24 sleeved on the guide rod 25. After the spring 24 is compressed, the elastic force of the spring 24 is applied to the fabric through the pressure block 27, thereby pressing the fabric tightly between the pressure block 27 and the cutter holder 1. Since the distance between the pressure block 27 and the cutter holder 1 is less than the distance between the cutter 19 and the cutter holder 1, the pressure block 27 first presses the fabric before the cutter 19 cuts the fabric. As the connecting plate 20 continues to move downward, the cutter 19 connected to the lower end of the connecting plate 20 also continues to move downward, eventually cutting the fabric. Then, the ultrasonic heater 28 heats the cut edge of the fabric to avoid producing rough edges at the cut edge of the fabric.
