A needle acupuncture machine based on intelligent tension adjustment

Abstract

This invention relates to the field of needle punching machine technology and discloses a needle punching machine based on intelligent tension adjustment, including a needle punching machine, a support frame, a material rack, and a controller. The support frame is fixedly connected to one side of the needle punching machine. By setting a tension adjustment mechanism, when insufficient tension occurs during the nonwoven fabric conveying process, the image acquisition device will capture the wrinkles caused by insufficient tension in the nonwoven fabric and transmit the information to the controller. At this time, the built-in PLC module of the controller will start the cylinder, which will push the mating box to move upward. The first piston plate, the first pushing block, and the connecting block in the mating box will also move upward synchronously. The connecting block will drive the linkage block and the two first sleeves to move upward. The positioning block and the tensioning roller will also move upward synchronously with the first sleeve. By having the upper surface of the tensioning roller abut against the bottom of the nonwoven fabric, the tension of the nonwoven fabric is intelligently adjusted, improving the subsequent piercing effect of the nonwoven fabric and thus improving the working efficiency of the needle punching machine.

Description

Technical Field

[0001] This invention relates to the field of acupuncture machine technology, specifically to an acupuncture machine based on intelligent tension adjustment. Background Technology

[0002] A needle punching machine is a device used for nonwoven fabrics. It utilizes needles with triangular or other shaped cross-sections and barbs on their edges to repeatedly pierce the fiber web. The fiber web, fed into the needle punching machine from a cross-linking or air-laid machine, is very loose, possessing only a certain strength generated by the cohesion between fibers, but this strength is very weak. When multiple needles pierce the web, the barbs on the needles cause the fibers on the surface and subsurface of the web to move from the planar direction to the vertical direction, causing the fibers to shift vertically. This vertical displacement of the fibers exerts a certain amount of pressure on the web, causing the fibers within the web to clump together and be compressed.

[0003] A search revealed a Chinese patent document disclosing a needle-punching machine with a tension adjustment device [Announcement No.: CN217125876U]. This machine includes: a support frame, a transmission platform mounted on the support frame, multiple sets of transmission rollers, a conveyor belt, and a tension adjustment device. The bottom of the transmission platform has symmetrically arranged mounting sections with guide grooves parallel to the transmission direction. The conveyor belt is connected end-to-end and can rotate cyclically under the drive of the transmission platform and transmission rollers. The tension adjustment device includes a tension roller and two sets of adjustment components symmetrically arranged on the mounting section. Each adjustment component includes a bearing seat, a push-pull rod, and a drive component. The bearing seat is located within the guide groove and can move along it. The tension roller is in contact with the conveyor belt and its two ends are rotatably connected to the bearing seat. One end of the push-pull rod is connected to the bearing seat, and the other end is connected to the drive component. The drive component drives the push-pull rod to move the tension roller along the guide groove. This device enables real-time adjustment of the conveyor belt tension, ensuring synchronous transmission between the precast sheet and the conveyor belt and a constant needle-punching step size.

[0004] During the needle punching process, the non-woven fabric in the material rack enters the needle punching machine for piercing. However, during the conveying process, the non-woven fabric may wrinkle on the surface due to insufficient tension, which affects the piercing effect. In this case, the needle punching machine usually needs to be stopped manually and the tension of the non-woven fabric needs to be readjusted before it can be put back into use, which reduces the efficiency of the needle punching machine.

[0019] Preferably, a limiting slide rod is fixedly connected to the bottom of the first sleeve, and a limiting slide groove is provided on the top of the support frame to cooperate with the limiting slide rod.

[0020] Preferably, a protective ring is fixedly connected to the surface of the smoothing roller, and the protective ring is made of rubber.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. This invention, by setting a tension adjustment mechanism, enables the image acquisition device to capture the wrinkles caused by insufficient tension in the nonwoven fabric during the conveying process, and transmits the information to the controller. At this time, the built-in PLC module of the controller will start the cylinder, which will push the mating box to move upward. The first piston plate, the first pushing block and the connecting block in the mating box will also move upward synchronously. The connecting block will drive the linkage block and the two first sleeves to move upward. The positioning block and the tensioning roller will also move upward synchronously with the first sleeve. By having the upper surface of the tensioning roller press against the bottom of the nonwoven fabric, the tension of the nonwoven fabric is intelligently adjusted, which improves the piercing effect of the nonwoven fabric and thus improves the working efficiency of the needle punching machine.

[0023] 2. This invention, through the setting of a transmission mechanism, enables the controller's built-in PLC module to start the motor simultaneously when the image acquisition device captures the wrinkle pattern. When the motor starts, it drives the first bevel gear to rotate, which in turn drives the second bevel gear and the lead screw to rotate around the bearing. Simultaneously, the two sliding blocks move to opposite sides, driving the second sleeve and the second sleeve to move. The two smoothing rollers also move away from each other along with the second sleeve. The two smoothing rollers move to both sides, smoothing the wrinkles on the non-woven fabric surface. When the sliding block moves to contact the first touch sensor, the first touch sensor transmits a signal to the controller. The built-in PLC module activates the electric push rod, which pushes the first set of rods upward, thereby driving the transmission housing and other structures upward. At this time, the two sliding blocks move towards each other under the drive of the lead screw. Meanwhile, the smoothing roller does not contact the non-woven fabric during its movement. When the sliding block moves to contact the second touch sensor, the second touch sensor transmits a signal to the controller. The built-in PLC module of the controller activates the electric push rod again, driving the first set of rods downward, thereby making the smoothing roller contact the upper surface of the non-woven fabric. This cycle repeats, and the smoothing roller moves in a slot-shaped trajectory to smooth and remove wrinkles from the non-woven fabric, effectively removing wrinkles from the fabric surface and improving the subsequent piercing effect.

[0024] 3. By setting up a pressurization mechanism, the present invention enables the sliding block to move towards the gas collection box while simultaneously driving the second sleeve rod to contact the extrusion block. The extrusion block, under pressure, drives the traction rod, the second pushing block, and the second piston plate to move away from the second sleeve rod. As the second piston plate moves, it compresses the air in the gas collection box, allowing the air in the gas collection box to enter the mating box through the transmission pipe. When the second sleeve rod moves to a point where it is no longer in contact with the extrusion block, the tension generated by the tension spring drives the second pushing block and the second piston plate to reset. At this time, the gas collection box is under negative pressure, and the gas enters the interior of the gas collection box through the air inlet pipe. This cycle continues, intermittently injecting gas into the mating box. Under the pressure of the gas, the first piston plate, the first pushing block, the connecting block, the linkage block, and the second sleeve will intermittently move upward, thereby driving the positioning block and the tension roller to move upward intermittently. By keeping the tension roller always against the bottom of the nonwoven fabric, the tension of the nonwoven fabric is increased.

[0025] 4. By setting up a pressure relief pipe and a one-way pressure valve, the present invention can compress the gas when the upper surface of the tensioning roller contacts the bottom of the nonwoven fabric and then injects gas into the mating box. When the gas pressure exceeds the limit of the one-way pressure valve, the gas will be intermittently ejected from the pressure relief pipe, preventing the tensioning roller from rising and thus avoiding excessive tension of the nonwoven fabric.

[0026] 5. By setting an adjustment mechanism, the present invention can make the hand screw leave the inside of the positioning hole by turning the hand screw. At this time, the height of the second sleeve and the smoothing roller can be adjusted along the trajectory of the second sleeve rod. After reaching the appropriate position, the hand screw is turned in the opposite direction so that one end of the hand screw enters the corresponding positioning hole, thereby completing the adjustment of the height of the smoothing roller.

[0039] 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.

[0040] Please see Figures 1 to 11 As shown,

[0041] Example 1:

[0042] A needle punching machine based on intelligent tension adjustment includes a needle punching machine 1, a support frame 2, a material rack 3, and a controller 4. The support frame 2 is fixedly connected to one side of the needle punching machine 1, the material rack 3 is located on one side of the support frame 2, and the controller 4 is fixedly installed on one side of the needle punching machine 1. A tension roller 5 is provided on the top of the support frame 2. Positioning blocks 6 are rotatably connected to both sides of the tension roller 5 through rotating shafts. A first sleeve 7 is fixedly connected to one side of the positioning block 6. A first sleeve rod 8 is slidably connected to the inner wall of the first sleeve 7. The two first sleeve rods 8 are fixedly connected at their connection points through a transmission housing 9. Two smoothing rollers 10 are provided at the bottom of the transmission housing 9, and a transmission mechanism for driving the smoothing rollers 10 is provided at the top of the transmission housing 9.

[0043] It also includes a tension adjustment mechanism, which is fixedly installed on one side of the needle punching machine 1. When the nonwoven fabric is not tensioned enough and wrinkles occur, the height of the tension roller 5 is adjusted.

[0044] The tension adjustment mechanism includes a support plate 11 and a connecting frame 12 fixedly connected to one side of the acupuncture machine 1. The two first sleeves 7 are connected by a linkage block 13. A mating box 14 is provided at the bottom of the linkage block 13. A first piston plate 15 is provided inside the mating box 14. A first push block 16 is fixedly connected to the top of the first piston plate 15. A connecting block 17 is fixedly connected to the top of the first push block 16. The top of the connecting block 17 extends through to the top of the mating box 14 and is fixedly connected to the bottom of the linkage block 13. Two cylinders 18 are fixedly installed on the top of the support plate 11. The output end of the cylinders 18 is fixedly connected to the bottom of the mating box 14.

[0045] An image acquisition device 19 is fixedly installed at the bottom of the connecting frame 12.

[0046] In this embodiment, considering that during the processing of the needle punching machine 1, the non-woven fabric in the material rack 3 will enter the needle punching machine 1 for piercing, but during the conveying process, the non-woven fabric may wrinkle due to insufficient tension, affecting the piercing effect. Therefore, by setting a tension adjustment mechanism, when insufficient tension occurs during the conveying process of the non-woven fabric, the image acquisition device 19 will capture the wrinkles caused by insufficient tension in the non-woven fabric and transmit the information to the controller 4. At this time, the built-in PLC module of the controller 4 will start the cylinder 18, which will push the mating box 14 to move upward. The first piston plate 15, the first pushing block 16 and the connecting block 17 in the mating box 14 will also move upward synchronously. The connecting block 17 will drive the linkage block 13 and the two first sleeves 7 to move upward. The positioning block 6 and the tensioning roller 5 will also move upward synchronously with the first sleeve 7. By having the upper surface of the tensioning roller 5 press against the bottom of the non-woven fabric, the tension of the non-woven fabric can be intelligently adjusted, thereby improving the piercing effect of the non-woven fabric and improving the working efficiency of the needle punching machine 1.

[0047] The bottom of the first sleeve 7 is fixedly connected to a limiting slide rod 46, and the top of the support frame 2 is provided with a limiting slide groove 47 that cooperates with the limiting slide rod 46.

[0048] In this embodiment, by setting the limiting slide bar 46 and the limiting slide groove 47, when the cylinder 18 pushes the first sleeve 7 and other structures to move, it can be restricted to move only along the trajectory of the limiting slide bar 46 and the limiting slide groove 47, thereby limiting the movement trajectory and improving the stability during the movement process.

[0049] Example 2:

[0050] Based on Embodiment 1, in this embodiment, the tension adjustment mechanism can increase the tension of the nonwoven fabric by adjusting the height of the tension roller when the nonwoven fabric wrinkles due to insufficient tension, thereby improving the subsequent nonwoven fabric piercing. However, considering that if the wrinkles in the transverse part of the nonwoven fabric cannot disappear after tension adjustment, it will still affect the subsequent piercing effect, the transmission mechanism in this application includes a motor 20 fixedly installed on the top of the transmission housing 9. The output end of the motor 20 extends into the inside of the transmission housing 9 and is fixedly connected to a first bevel gear 21. Both sides of the first bevel gear 21 are meshed with second bevel gears 22. The two second bevel gears 22 are fixedly connected to the side away from each other by a lead screw 23. One end of the lead screw 23 is rotatably connected to the inner wall of the transmission housing 9 through a bearing. A sliding block 24 is transmittedly connected to the surface of the lead screw 23. A second sleeve 25 is fixedly connected to one side of the smoothing roller 10. A second sleeve rod 26 is slidably connected to the inner wall of the second sleeve 25. The top of the second sleeve rod 26 is fixedly connected to the bottom of the sliding block 24. An adjustment mechanism is provided on one side of the second sleeve 25.

[0051] An electric push rod 27 is fixedly installed inside the first sleeve 7. The output end of the electric push rod 27 is fixedly connected to the bottom of the first sleeve 8. A first touch sensor 28 that works with the sliding block 24 is fixedly connected to both sides of the inner wall of the transmission housing 9. Two second touch sensors 29 are fixedly connected to the bottom of the inner wall of the transmission housing 9.

[0052] In this embodiment, by setting a transmission mechanism, when the image acquisition device 19 captures the wrinkled pattern, the built-in PLC module of the controller 4 will also start the motor 20, such as... Figure 9As shown, when the motor 20 starts, it drives the first bevel gear 21 to rotate. The first bevel gear 21 drives the second bevel gear 22 and the lead screw 23 to rotate around the bearing. While the lead screw 23 rotates, the two sliding blocks 24 move to the side away from each other, simultaneously driving the second sleeve 26 and the second sleeve 25 to move. The two smoothing rollers 10 also move to the side away from each other along with the second sleeve 25. The two smoothing rollers 10 move to both sides respectively, smoothing the wrinkles on the surface of the non-woven fabric. When the sliding block 24 moves to contact the first touch sensor 28, the first touch sensor 28 transmits a signal to the controller 4. The built-in PLC module of the controller 4 starts the electric push rod 27. 27 will push the first set of rods 8 upward, thereby driving the transmission housing 9 and other structures upward. At this time, the two sliding blocks 24 will move towards each other under the transmission of the lead screw 23. Meanwhile, the smoothing roller 10 does not contact the non-woven fabric during its movement. When the sliding block 24 moves to contact the second touch sensor 29, the second touch sensor 29 will transmit a signal to the controller 4. The built-in PLC module of the controller 4 will restart the electric push rod 27, driving the first set of rods 8 downward, thereby making the smoothing roller 10 contact the upper surface of the non-woven fabric. This cycle continues, and the smoothing roller 10 moves in a slot-shaped trajectory to smooth and remove wrinkles from the non-woven fabric, effectively removing wrinkles from the fabric surface and improving the subsequent piercing effect.

[0053] It should be noted that; Figure 9 S1 is the movement trajectory of the electric push rod 27 after the sliding block 24 touches the first touch sensor 28, and S2 is the movement trajectory of the sliding block 24 in the current state.

[0054] S3 is the movement trajectory of the electric push rod 27 when the slider 24 touches the second touch sensor 29, and S4 is the movement trajectory of the slider 24 in the current state.

[0055] The adjustment mechanism includes a hand screw 43 threaded to one side of the second sleeve 25, a threaded hole 44 for cooperating with the hand screw 43 on one side of the second sleeve 25, and a positioning hole 45 for cooperating with the hand screw 43 on one side of the second sleeve rod 26. The number of positioning holes 45 is several.

[0056] In this embodiment, considering the different thicknesses of nonwoven fabrics, the thickness of the smoothing roller 10 needs to be adjusted in advance according to the thickness of the nonwoven fabric. Therefore, by setting an adjustment mechanism, the hand screw 43 can be turned away from the inside of the positioning hole 45 by turning the hand screw 43. At this time, the height of the second sleeve 25 and the smoothing roller 10 can be adjusted along the trajectory of the second sleeve rod 26. After reaching the appropriate position, the hand screw 43 is turned in the opposite direction so that one end of the hand screw 43 enters the corresponding positioning hole 45, thus completing the adjustment of the height of the smoothing roller 10.

[0057] A protective ring 48 is fixedly connected to the surface of the smoothing roller 10. The protective ring 48 is made of rubber.

[0058] In this embodiment, the protective ring 48 can play a protective role, avoiding the smoothing roller 10 from contacting the non-woven fabric and causing large wear.

[0059] Example 3:

[0060] Based on Embodiment 2, in this embodiment, the smoothing roller 10 can smooth out the wrinkles on the non-woven fabric. However, considering that after the wrinkles on the non-woven fabric are smoothed out, the tension of the non-woven fabric itself will decrease, which will affect the subsequent piercing effect, this application also includes a pressure boosting mechanism, which is fixedly set on one side of the first sleeve rod 8.

[0061] The pressurization mechanism includes an air collection box 30 fixedly connected to one side of the first sleeve rod 8. The top of the air collection box 30 is fixedly connected to an air inlet pipe 31 through a first one-way valve. One side of the air collection box 30 is fixedly connected to a transmission pipe 32 through a second one-way valve. One end of the transmission pipe 32 is fixedly connected to the bottom of the mating box 14.

[0062] A second piston plate 33 is fixedly connected to the inner wall of the air collection box 30. A second push block 34 is fixedly connected to one side of the second piston plate 33. A traction rod 35 is fixedly connected to one side of the second push block 34. One end of the traction rod 35 extends through to one side of the first sleeve rod 8 and is fixedly connected to a compression block 36. The compression block 36 is positioned opposite to the second sleeve rod 26. A tension spring 37 is sleeved on the surface of the traction rod 35. One end of the tension spring 37 is fixedly connected to one side of the second push block 34, and the other side of the tension spring 37 is fixedly connected to the inner wall of the air collection box 30.

[0063] In this embodiment, by setting a pressurization mechanism, while the sliding block 24 moves towards the side closer to the air collection box 30, the sliding block 24 will drive the second sleeve rod 26 to contact the compression block 36. The compression block 36, when compressed, will drive the traction rod 35, the second pushing block 34, and the second piston plate 33 to move away from the second sleeve rod 26. As the second piston plate 33 moves, it will compress the air in the air collection box 30, causing the air in the air collection box 30 to enter the mating box 14 through the transmission pipe 32. When the second sleeve rod 26 moves to a point where it is no longer in contact with the compression block 36, the tension spring 3... The tension generated by 7 will drive the second push block 34 and the second piston plate 33 to reset. At this time, the air collection box 30 is under negative pressure, and the gas will enter the interior of the air collection box 30 through the air inlet pipe 31. The gas is injected into the mating box 14 intermittently in sequence. Under the compression of the gas, the first piston plate 15, the first push block 16, the connecting block 17, the linkage block 13 and the second sleeve 25 will move upward intermittently, thereby driving the positioning block 6 and the tension roller 5 to move upward intermittently. By keeping the tension roller 5 against the bottom of the nonwoven fabric, the tension of the nonwoven fabric is improved.

[0064] It should be noted that the first check valve is a valve that can only allow air to enter the air collection box 30, and the second check valve is a valve that can only exhaust air from the air collection box 30.

[0065] A pressure relief pipe 38 is fixedly connected to one side of the fitting box 14, and a one-way pressure valve 39 is fixedly installed on the surface of the pressure relief pipe 38.

[0066] In this embodiment, considering that if gas is continuously injected into the mating box 14, causing the tension roller 5 to rise intermittently, it may also cause excessive tension in the nonwoven fabric, a pressure relief pipe 38 and a one-way pressure valve 39 are provided. When the upper surface of the tension roller 5 contacts the bottom of the nonwoven fabric, injecting gas into the mating box 14 will compress the gas. When the gas pressure exceeds the limit of the one-way pressure valve 39, the gas will be intermittently ejected from the pressure relief pipe 38, preventing the tension roller 5 from rising and thus avoiding excessive tension in the nonwoven fabric.

[0067] An exhaust pipe 40 is fixedly connected to the bottom of the mating box 14, and a solenoid valve 41 is fixedly installed on the surface of the exhaust pipe 40.

[0068] In this embodiment, by setting up an exhaust pipe 40 and a solenoid valve 41, after the nonwoven fabric is processed, the gas in the mating box 14 can be completely discharged by activating the solenoid valve 41, so that it can be reused in the future.

[0069] Two springs 42 are fixedly connected to the top of the first push block 16, and the top of the springs 42 is fixedly connected to the inner wall of the mating box 14.

[0070] In this embodiment, by setting a spring 42, when the gas in the mating box 14 is discharged through the exhaust pipe 40, the elastic force generated by the spring 42 will assist the first push block 16 and the first piston plate 15 to move downward, which plays a role in resetting and at the same time increases the rate of gas discharge in the mating box 14.

[0071] The working principle and usage process of this invention: When insufficient tension occurs during the nonwoven fabric conveying process, the image acquisition device 19 will capture the wrinkles caused by insufficient tension in the nonwoven fabric and transmit the information to the controller 4. At this time, the built-in PLC module of the controller 4 will start the cylinder 18, which will push the mating box 14 to move upward. The first piston plate 15, the first pushing block 16 and the connecting block 17 in the mating box 14 will also move upward synchronously. The connecting block 17 will drive the linkage block 13 and the two first sleeves 7 to move upward. The positioning block 6 and the tensioning roller 5 will also move upward synchronously with the first sleeve 7. By having the upper surface of the tensioning roller 5 press against the bottom of the nonwoven fabric, the tension of the nonwoven fabric is intelligently adjusted, which improves the subsequent nonwoven fabric piercing effect and thus improves the working efficiency of the needle punching machine 1.

[0072] When the image acquisition unit 19 captures the wrinkled pattern, the built-in PLC module of the controller 4 will also start the motor 20, such as Figure 9 As shown, when the motor 20 starts, it drives the first bevel gear 21 to rotate. The first bevel gear 21 drives the second bevel gear 22 and the lead screw 23 to rotate around the bearing. While the lead screw 23 rotates, the two sliding blocks 24 move to the side away from each other, simultaneously driving the second sleeve 26 and the second sleeve 25 to move. The two smoothing rollers 10 also move to the side away from each other along with the second sleeve 25. The two smoothing rollers 10 move to both sides respectively, smoothing the wrinkles on the surface of the non-woven fabric. When the sliding block 24 moves to contact the first touch sensor 28, the first touch sensor 28 transmits a signal to the controller 4. The built-in PLC module of the controller 4 starts the electric push rod 27. 27 will push the first set of rods 8 upward, thereby driving the transmission housing 9 and other structures upward. At this time, the two sliding blocks 24 will move towards each other under the transmission of the lead screw 23. Meanwhile, the smoothing roller 10 does not contact the non-woven fabric during its movement. When the sliding block 24 moves to contact the second touch sensor 29, the second touch sensor 29 will transmit a signal to the controller 4. The built-in PLC module of the controller 4 will restart the electric push rod 27, driving the first set of rods 8 downward, thereby making the smoothing roller 10 contact the upper surface of the non-woven fabric. This cycle continues, and the smoothing roller 10 moves in a slot-shaped trajectory to smooth and remove wrinkles from the non-woven fabric, effectively removing wrinkles from the fabric surface and improving the subsequent piercing effect.

[0073] As the sliding block 24 moves closer to the air collection box 30, it causes the second sleeve rod 26 to contact the compression block 36. The compression block 36, being compressed, causes the traction rod 35, the second pushing block 34, and the second piston plate 33 to move away from the second sleeve rod 26. As the second piston plate 33 moves, it compresses the air in the air collection box 30, allowing the air in the air collection box 30 to enter the mating box 14 through the transmission pipe 32. When the second sleeve rod 26 moves to a point where it no longer contacts the compression block 36, the tension force generated by the tension spring 37 will... When the second push block 34 and the second piston plate 33 are reset, the air collection box 30 is under negative pressure. The gas will then enter the interior of the air collection box 30 through the air inlet pipe 31 and circulate in sequence, intermittently injecting gas into the mating box 14. Under the compression of the gas, the first piston plate 15, the first push block 16, the connecting block 17, the linkage block 13, and the second sleeve 25 will intermittently move upward, thereby driving the positioning block 6 and the tension roller 5 to move upward intermittently. By keeping the tension roller 5 against the bottom of the nonwoven fabric, the tension of the nonwoven fabric is increased.

[0074] It should be noted that the controller 4, cylinder 18, image acquisition device 19, motor 20, electric push rod 27, first touch sensor 28, second touch sensor 29, and solenoid valve 41 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Furthermore, the specific composition and principle of the power supply of the controller 4, cylinder 18, image acquisition device 19, motor 20, electric push rod 27, first touch sensor 28, second touch sensor 29, and solenoid valve 41 are clear to those skilled in the art, and therefore will not be described in detail.
