Description

Technical Field

[0001] The present invention relates to the technical field of advertising design, and more specifically, to a fabric punching device for advertising design. Background Art

[0002] In advertising design, using fabric as a carrier can create unique and eye-catching visual effects, especially suitable for scenarios such as exhibitions, events, retail spaces, brand promotion, etc. Punching holes in the fabric is a common craftsmanship method, which can not only meet functional requirements (such as ventilation, weight reduction, installation and fixation), but also enhance the visual creative effect (such as hollow patterns, light penetration); However, the existing fabric punching devices for advertising design have the following deficiencies when punching fabrics: The punching drill on the puncher descends vertically to punch the fabric, generating a large downward impact force. The poor buffering effect when the punching drill contacts the fabric easily causes tearing at the punching position of the fabric, reducing the punching forming effect; Moreover, the shredded fabric pieces after punching are easily blocked inside the punching drill, and the fabric enters below the punching drill through transmission, and the two sides of the fabric punching position cannot be effectively tensioned, and the fabric is in a loose state, resulting in the punching drill being unable to effectively punch the fabric. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is as follows: A fabric punching device for advertising design, the structure of which includes a punching table, a unwind roller control panel, a servo motor, a control box, a motor and a top cover. A unwind roller is installed at the front end of the punching table, and a fabric is wound around the surface of the unwind roller. The fabric is laid flat on the upper surface of the punching table and inside the top cover fixed on the upper surface of the punching table. The control panel and the servo motor are both installed on the right side surface of the top cover. A control box is fixedly installed on the top of the top cover. The control box is electrically connected to the control panel, the servo motor and the motor arranged on the right side surface at the rear end of the punching table. A pulley is arranged at the output end of the motor, and there are two pulleys. A belt is connected between the two pulleys, and another pulley is connected to a winding roller. The winding roller is arranged at the rear end of the punching table to wind the other end of the fabric. A worm is welded to the output end of the servo motor, and the worm is arranged inside the top cover. A slider penetrates through the outside of the worm and is threadedly connected. A locking clamp is arranged at the front end of the slider, and the locking clamp locks and fixes the support plate arranged at the front end of the slider. A side sliding plate is also arranged on the side of the slider. The side sliding plate is slidably installed on the outside of the worm and is threadedly connected. A guide post penetrates through the lower end inside the side sliding plate. The guide post is fixedly installed inside the top cover and is located directly below the worm. A reinforcing support rod is fixed to the lower end of the side sliding plate. The reinforcing support rod is installed at an inclined angle, and the upper end of the reinforcing support rod supports the outer bottom surface of the support plate. There are two side sliding plates, and the two side sliding plates are distributed on both sides of the slider, and are connected to the left and right sides of the support plate at the same time, ensuring that when the servo motor drives the worm to rotate, the slider and the side sliding plate can be stably driven to slide synchronously, driving the support plate to displace, and adjusting the punching position of the fabric as the support plate moves.

[0004] As a further improvement of the present invention, a cylinder is fixedly installed on the upper surface of the support plate, and a pressing rod is welded to the output end of the lower end of the cylinder. The pressing rod passes through the middle part inside the support plate by means of clearance fit. A connecting head is connected to the lower end of the pressing rod, and a punching drill bit is installed at the lower end of the connecting head. A linkage rod is arranged outside the connecting head and is pivotally connected. A sliding block is arranged at the upper end of the linkage rod and is pivotally connected. The sliding block is embedded in the lower end inside the support plate, and a spring guide rod is installed at the lower end inside the support plate. The sliding block is slidably installed on the outside of the spring guide rod. There are two linkage rods, sliding blocks and spring guide rods, and they are symmetrically installed on both sides of the connecting head and both sides of the bottom of the support plate.

[0005] As a further improvement of the present invention, an internally threaded tube is fixedly installed at the bottom of the connector head, and the inside of the internally threaded tube is threadedly connected to the outer side of the upper end of the drilling bit. A compression spring is fixedly installed inside the connector head, and a push rod is connected to the lower end of the compression spring. The upper end of the push rod is installed in the middle inside the connector head with a clearance fit. The lower end of the push rod is welded with a pressing ball, and both the push rod and the pressing ball are located at the central position inside the drilling bit. When the drilling bit descends to punch holes in the fabric, the push rod and the pressing ball are elastically extruded upward. After the punching is completed, the shredded fabric pieces enter the inside of the drilling bit. When the drilling bit moves upward for reset, under the elastic reset applied by the compression spring, the push rod and the pressing ball descend to extrude the shredded fabric pieces inside the drilling bit.

[0006] As a further improvement of the present invention, an expander is also installed inside the top cover. The expander consists of an electric push rod, a linkage plate, a long connecting plate, a hinge plate, and a tensioning roller. The electric push rod is fixedly installed inside the top cover, and the output end of the lower end of the electric push rod is axially connected to the upper end of the linkage plate. The lower end of the linkage plate is axially connected to the upper surface of the long connecting plate. Hinge plates are fixedly installed on the lower surfaces on both sides of the long connecting plate. The two hinge plates axially connect the two ends of the axis of the tensioning roller. A roller is also arranged on the upper surface of the punching table, and the roller is located below the tensioning roller. A sliding shaft is arranged outside the axis of the hinge plate of the tensioning roller, and a support piece is fitted and installed on the right side of the sliding shaft. Both the sliding shaft and the support piece are slidably installed inside a spring slide rail arranged on the inner wall of the top cover. Two expanders are symmetrically installed at both ends of the front end inside the top cover in the front and back directions. Each expander has three electric push rods and linkage plates, which are distributed in the middle and at both ends of the long connecting plate. When the drilling bit descends to punch holes in the fabric, the three electric push rods descend synchronously and, under the linkage support of the linkage plate, the tensioning roller at the lower end of the long connecting plate rolls on the surface of the fabric.

[0007] As a further improvement of the present invention, a lower support plate is also installed in the middle of the surface of the punching table. An anti-slip sheet is attached to the upper surface of the lower support plate to support the bottom surface of the fabric. A lower discharge groove penetrates through the center of the lower support plate, and the lower discharge groove is located directly below the drilling bit. A support and pressing rod is welded to the outside of the bottom of the lower support plate, and the lower end of the support and pressing rod is installed in a spring tube sleeve arranged at the upper end of the punching table with a clearance fit. A lower discharge hopper is fixed to the center of the bottom of the lower support plate, and the lower discharge hopper is located directly below the lower discharge groove. A connecting hose is connected to the bottom of the lower discharge groove, and the lower end of the connecting hose is fixed to the middle of the upper end of a negative pressure chamber arranged inside the punching table. A dust collector is connected to the outside of the negative pressure chamber. There are four support and pressing rods and spring tube sleeves, which are distributed at the four corners of the bottom of the lower support plate to provide a stable elastic lifting support force for the whole lower support plate. When the drilling bit presses down on the fabric to punch holes, the lower support plate can play a certain role in buffering the descent. While buffering the descent, the connecting hose is squeezed and contracted.

[0008] As a further improvement of the present invention, a drawer is slidably installed inside the negative pressure chamber, and a support slide rail is fixedly installed inside the negative pressure chamber to support the bottom of the drawer. A through hole penetrates through the bottom of the drawer and is connected to a dust collector through the negative pressure chamber. The through hole is a cavity structure with a narrow upper end and a wide lower end, and multiple through holes are distributed at the bottom of the drawer.

[0009] The beneficial effects of the present invention are as follows: 1. When the air cylinder is started to descend, driven by the lower pressing rod, the connecting head and the punching drill bit descend to punch the cloth below. Through the linkage of the two side linkage support rods, and the sliding block elastically slides on the outside of the spring guide rod, thereby elastically buffering the lifting of the punching drill bit. At the same time, the lower support plate is elastically supported and cooperated by the support pressing rod and the spring tube sleeve, and the lower support plate on the lower surface of the cloth provides a stable elastic lifting support force, avoiding the tearing of the cloth punching position due to excessive downward impact force and improving the punching forming effect; 2. After punching, the shredded cloth pieces enter the punching drill bit. When the punching drill bit moves upward for resetting, under the elastic reset applied by the compression spring, the ejector rod and the pressure ball descend to extrude the shredded cloth pieces inside the punching drill bit, effectively avoiding the accumulation of shredded cloth pieces inside the punching drill bit and ensuring that the punching drill bit effectively punches the cloth; 3. The three electric push rods descend synchronously and are supported by the linkage of the linkage plate, so that the long connecting plate moves to drive the tensioning rollers at the lower end to roll on the cloth surface. Through the elastic guiding and sliding of the sliding shaft and the supporting piece inside the spring slide rail, the rolling of the tensioning rollers is horizontally guided. The two tensioning rollers on the two outrigger devices roll and stretch the cloth back and forth, improving the self-tension of the cloth and ensuring the stable and accurate punching work of the punching drill bit on the cloth.

A compression spring 4331 is fixedly installed inside the connecting head 433. The lower end of the compression spring 4331 is connected with a top rod 4333. The upper end of the top rod 4333 is installed through the middle inside the connecting head 433 by means of clearance fit. A pressure ball 4334 is welded at the lower end of the top rod 4333. Both the top rod 4333 and the pressure ball 4334 are located at the central position inside the punching drill bit 434; A lower support plate 73 is further installed in the middle of the tabletop of the punching table 1. An anti-slip sheet 731 is attached to the upper surface of the lower support plate 73 to support the bottom surface of the fabric B. A lower discharge groove 732 penetrates through the center of the lower support plate 73. The lower discharge groove 732 is located directly below the punching drill bit 434. A support pressure rod 733 is also welded to the outer side of the bottom of the lower support plate 73.

A support slide rail 7363 is also fixedly installed inside the negative pressure chamber 736 to support the bottom of the drawer 7361. A through hole 7362 penetrates through the bottom of the drawer 7361 and is connected to the dust collector 737 through the negative pressure chamber 736 in a through manner; In the present invention, the driving motor 6 is started to drive the winding roller 63 to wind the fabric B, and the unwinding roller 2 is cooperated to unwind the fabric B, so that the fabric B is transported on the punching table 1 and enters the top cover 7. When the servo motor 4 is controlled to operate through the control panel 3 and the servo motor 4 drives the worm 41 to rotate, the slider 42 and the side slide plate 422 can be stably driven to slide synchronously, driving the support plate 43 to displace. As the support plate 43 moves, the position of the punching drill bit 434 for punching the fabric B is adjusted, so that the punching drill bit 434 can punch the fabric B at different positions. When punching, the air cylinder 431 is started to descend. Driven by the pressing rod 432, the connecting head 433 and the punching drill bit 434 descend to punch the fabric B below. The two side connecting rods 435 are used for linkage, and the sliding block 436 elastically slides outside the spring guide rod 437, so as to elastically buffer the lifting of the punching drill bit 434. At the same time, the lower support plate 73 is elastically supported by the support pressing rod 733 and the spring tube sleeve 734, and the lower support plate 73 on the lower surface of the fabric B provides a stable elastic lifting support force, avoiding tearing at the punching position of the fabric B due to excessive downward impact force and improving the punching forming effect.

At the same time, the dust collector 737 below works, so that negative pressure is generated in the negative pressure chamber 736 and the drawer 7361, and the shredded cloth pieces are sucked through the lower discharge groove 732, the lower discharge hopper 735 and the connecting hose 7351 into the drawer 7361 for centralized collection.

[0020] In a preferred technical solution, there are two side slide plates 422, and the two side slide plates 422 are distributed on both sides of the slider 42 and are connected to the left and right sides of the support plate 43 at the same time, ensuring that when the servo motor 4 drives the worm 41 to rotate, the slider 42 and the side slide plate 422 can be stably driven to slide synchronously, driving the support plate 43 to displace. As the support plate 43 moves, the punching position of the fabric B is adjusted, and under the support of the two reinforcing struts 424, the support plate 43 is ensured to maintain a horizontal state during displacement, preventing the support plate 43 from tilting in the horizontal state during displacement. A preferred technical solution is that there are two linkage rods 435, sliding blocks 436 and spring guide rods 437, which are symmetrically installed on both outer sides of the connecting head 433 and both sides of the bottom of the support plate 43. When the cylinder 431 descends and works, driving the drilling bit 434 at the bottom of the connecting head 433 to descend to drill holes in the fabric B, the two sides are linked through the linkage rods 435, and the sliding blocks 436 elastically slide on the outer sides of the spring guide rods 437, so as to elastically buffer the lifting of the drilling bit 434, avoid the tearing of the drilling position of the fabric B caused by excessive downward impact force, and improve the drilling forming effect; A preferred technical solution is that when the drilling bit 434 descends to drill holes in the fabric B, the ejector rod 4333 and the pressure ball 4334 are elastically extruded upward. After the drilling is completed, the shredded cloth pieces enter the inside of the drilling bit 434. When the drilling bit 434 moves upward to reset, under the elastic reset applied by the compression spring 4331, the ejector rod 4333 and the pressure ball 4334 descend to extrude the shredded cloth pieces inside the drilling bit 434, which can effectively prevent the shredded cloth pieces from accumulating inside the drilling bit 434 and ensure that the drilling bit 434 effectively drills holes in the fabric B; A preferred technical solution is that there are four support pressure rods 733 and spring tube sleeves 734, which are distributed at the four corners of the bottom of the lower support plate 73, providing a stable elastic lifting support force for the whole lower support plate 73. When the drilling bit 434 presses down to drill holes in the fabric B, the lower support plate 73 can play a certain role in descending buffer. At the same time of the descending buffer, the connecting hose 7351 is squeezed and contracted to ensure the communication between the lower discharge hopper 735 and the negative pressure chamber 736, so that the shredded cloth pieces generated by drilling enter the inside of the lower discharge groove 732. Under the operation of the dust collector 737, a negative pressure is generated inside the negative pressure chamber 736, and the shredded cloth pieces are sucked in and collected centrally; A preferred technical solution is that the through hole 7362 is a cavity structure with a narrow upper end and a wide lower end, and a plurality of them are arranged at the bottom of the drawer 7361. Through the plurality of through holes 7362, a through state is formed between the drawer 7361 inside the negative pressure chamber 736 and the dust collector 737, and the shredded cloth pieces can be sucked into the drawer 7361 for centralized collection.

And a roller 72 is also arranged on the upper surface of the punching table 1. The roller 72 is located below the tension roller 715. A sliding shaft 7151 is arranged outside the axis of the tension roller 715 and the hinge plate 714. And a support piece 7152 is fitted and installed on the right side of the sliding shaft 7151. Both the sliding shaft 7151 and the support piece 7152 are slidably installed inside a spring slide rail 7153 arranged on the inner wall of the top cover 7. In the present invention, during the punching process, while the cylinder 431 drives the punching drill bit 434 to descend, the electric push rod 711 starts to descend. The three electric push rods 711 descend synchronously and under the linkage support of the linkage plate 712, the long connecting plate 713 moves to drive the tension roller 715 at the lower end to roll on the surface of the fabric B. Through the elastic guiding and sliding of the sliding shaft 7151 and the support piece 7152 inside the spring slide rail 7153, the lateral guiding of the rolling of the tension roller 715 is carried out. The two tension rollers 715 on the two expanders 71 perform rolling stretching on the fabric B in the front and back directions, improving the self-tension of the fabric B and ensuring the stable and accurate punching work of the punching drill bit 434 on the fabric B.

And there are three electric push rods 711 and linkage plates 712 on each expander 71, and they are distributed in the middle and both ends of the long connecting plate 713. When the punching drill bit 434 descends to punch the fabric B, the three electric push rods 711 descend synchronously and under the linkage support of the linkage plate 712, the tension roller 715 at the lower end of the long connecting plate 713 rolls on the surface of the fabric B. The two tension rollers 715 on the two expanders 71 perform rolling stretching on the fabric B in the front and back directions, improving the self-tension of the fabric B and ensuring the stable and accurate punching work of the punching drill bit 434 on the fabric B.
