Description

Technical Field

[0001] The invention relates to the technical field of acupuncture machines, in particular to acupuncture machines based on intelligent tension regulation. Background Art

[0002] The needle loom is a device used for nonwoven fabrics. It uses a triangular or other shaped cross-section and barbed needles on the edges to repeatedly puncture the fiber web. The fiber web from the cross-web or air-web machine is very fluffy when fed into the needle loom. It only generates a certain strength due to the bonding force between the fibers, but the strength is very poor. When multiple needles penetrate the fiber web, the barbed needles on the needles will drive the fibers on the surface and sub-surface of the fiber web to move from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to shift up and down. The fibers that shift up and down will squeeze the fiber web to a certain extent, causing the fibers in the fiber web to be close together and compressed.

[0003] After searching, it is found that a Chinese patent document discloses a needling machine with a tension adjustment device [Announcement No.: CN217125876U]. It includes: a bracket, a transmission platform arranged on the bracket, multiple groups of transmission rollers, a conveyor belt and a tension adjustment device. The bottom of the transmission platform is symmetrically provided with a mounting portion having a guide groove parallel to the transmission direction; the conveyor belt is connected end to end and can be driven by the transmission platform and the transmission roller to make a circular rotation; the tension adjustment device includes a tension roller and two groups of adjustment components symmetrically arranged on the mounting portion, and the adjustment component includes a bearing seat, a push-pull rod and a driving member. The bearing seat is arranged in the guide groove and can move along the guide groove. The tension roller fits the conveyor belt and the two ends are rotatably connected to the bearing seat respectively. One end of the push-pull rod is connected to the bearing seat, and the other end is connected to the driving member. The driving member is used to drive the push-pull rod to drive the tension roller to move along the guide groove. The device can realize the adjustment of the tension of the conveyor belt at any time, ensuring the synchronous transmission of the plate preform and the conveyor belt and the constant needling step amount.

[0004] During the processing of the needling machine, the non-woven fabrics in the material rack will enter the needling machine for puncture. However, during the transportation process, the non-woven fabrics will cause wrinkles on the surface due to insufficient tension, which affects the puncture effect of the non-woven fabrics. In this case, it is generally necessary to manually stop the needling machine and readjust the strength of the non-woven fabrics before it can be put into use again, which reduces the efficiency of the needling machine.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a tension adjustment mechanism. When the tension is insufficient during the conveying process of the non-woven fabric, the image collector will capture the wrinkles of the non-woven fabric caused by the insufficient tension and transmit the information to the controller. At this time, the built-in PLC module of the controller will start the cylinder, and the cylinder will push the matching box to move upward. The first piston plate, the first push block and the connecting block in the matching box will also move upward synchronously. The connecting block will drive the linkage block and the two first sleeves to move upward, and the positioning block and the tensioning roller will also move upward synchronously with the first sleeve. The upper surface of the tensioning roller is against the bottom of the non-woven fabric, so as to realize the function of intelligently adjusting the tension of the non-woven fabric, improve the effect of subsequent non-woven fabric puncture, and thus improve the working efficiency of the acupuncture machine; 2. The present invention sets a transmission mechanism, and when the image collector captures the wrinkle pattern, the built-in PLC module of the controller will also start the motor. When the motor starts, it will drive the first bevel gear to rotate, and the first bevel gear will drive the second bevel gear and the screw to rotate around the bearing. When the screw rotates, the two sliding blocks will first move to the side away from each other, and at the same time drive the second set of rods and the second sleeve to move, and the two smoothing rollers will also move to the side away from each other with the second sleeve. The two smoothing rollers move to both sides respectively, and will smooth the wrinkles on the surface of the non-woven fabric. When the sliding block moves to contact with the first touch sensor, the first touch sensor will transmit a signal to the controller, and the controller The built-in PLC module will start the electric push rod, which will push the first set of rods upward, thereby driving the transmission housing and other structures upward. At this time, the two sliding blocks will just move to the side close to each other under the transmission of the screw rod. At the same time, the smoothing roller does not contact the non-woven fabric during the movement. When the sliding block moves to contact the second touch sensor, the second touch sensor will transmit a signal to the controller, and the built-in PLC module of the controller will start the electric push rod again, driving the first set of rods to move downward, thereby making the smoothing roller contact the upper surface of the non-woven fabric, and the cycle will be repeated. The smoothing roller moves in a mouth-shaped trajectory to smooth and de-wrinkle the non-woven fabric, which can effectively remove wrinkles on the surface of the fabric and improve the subsequent puncture effect. 3. The present invention provides a boosting mechanism, so that when the sliding block moves toward the side close to the air collecting box, the sliding block will drive the second set of rods to contact the extrusion block. The extrusion block will be squeezed and drive the traction rod, the second push block and the second piston plate to move toward the side away from the second set of rods. When the second piston plate moves, it will squeeze the air in the air collecting box, so that the air in the air collecting box enters the inside of the matching box through the transmission pipe. When the second set of rods moves to no longer contact the extrusion block, the tension generated by the tension spring will drive the second push block and the second piston plate to reset. At this time, the air collecting box is under negative pressure, and the gas will enter the inside of the air collecting box through the intake pipe, circulate in sequence, and intermittently inject gas into the matching box. Under the extrusion of the gas, the first piston plate, the first push block, the connecting block, the linkage block, the second sleeve and other structures will intermittently move upward, thereby driving the positioning block and the tensioning roller to move upward intermittently, and the tension of the non-woven fabric is increased by making the tensioning roller always against the bottom of the non-woven fabric. 4. The present invention provides a pressure relief pipe and a one-way pressure valve. When the upper surface of the tensioning roller contacts the bottom of the non-woven fabric, injecting gas into the matching box will compress the gas. When the gas pressure exceeds the limit of the one-way pressure valve, the gas will be intermittently ejected from the pressure relief pipe, making it impossible for the tensioning roller to rise, thereby avoiding the occurrence of excessive tension of the non-woven fabric. 5. The present invention provides an adjustment mechanism, which can make the hand screw leave the interior 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 set of rods. After reaching the appropriate position, the hand screw is turned in the reverse direction to make one end of the hand screw enter the corresponding positioning hole, thereby completing the adjustment of the height of the smoothing roller.

[0020] See also Figures 1 to 11 As shown, Embodiment 1: A needling machine based on intelligent tension adjustment comprises a needling machine 1, a support frame 2, a material frame 3 and a controller 4, wherein the support frame 2 is fixedly connected to one side of the needling machine 1, the material frame 3 is located at one side of the support frame 2, the controller 4 is fixedly installed at one side of the needling machine 1, a tensioning roller 5 is arranged on the top of the support frame 2, both sides of the tensioning roller 5 are rotatably connected to positioning blocks 6 through a rotating shaft, a first sleeve 7 is fixedly connected to one side of the positioning block 6, a first sleeve 7 is slidably connected to the inner wall of the first sleeve 7, and the two first sleeve rods 8 are fixedly connected at the connection point through a transmission housing 9, two smoothing rollers 10 are arranged at the bottom of the transmission housing 9, and a transmission mechanism for driving the smoothing roller 10 is arranged on the top of the transmission housing 9.

[0021] It also includes a tension adjustment mechanism, which is fixedly arranged on one side of the needling machine 1. When the nonwoven fabric has insufficient tension and wrinkles appear, the height of the tension roller 5 is adjusted; 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 fixedly connected at the connection point through a linkage block 13. A matching box 14 is provided at the bottom of the linkage block 13. A first piston plate 15 is provided inside the matching 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 penetrates to the top of the matching 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 cylinder 18 is fixedly connected to the bottom of the matching box 14. An image collector 19 is fixedly mounted on the bottom of the connecting frame 12 .

[0022] In this embodiment, it is considered that during the processing of the needling machine 1, the non-woven fabric in the material rack 3 will enter the needling machine 1 for puncture. However, during the transportation of the non-woven fabric, wrinkles will appear on the surface due to insufficient tension, which affects the puncture effect of the non-woven fabric. Therefore, by setting a tension adjustment mechanism, when insufficient tension occurs during the transportation of the non-woven fabric, the image collector 19 will capture the wrinkles of the non-woven fabric caused by insufficient tension 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, and the cylinder 18 will push the matching box 14 to move upward.

The connecting block 17 will drive the linkage block 13 and the two first sleeves 7 to move upward, and the positioning block 6 and the tensioning roller 5 will also move upward synchronously with the first sleeve 7. The upper surface of the tensioning roller 5 is against the bottom of the non-woven fabric, so as to realize the function of intelligently adjusting the tension of the non-woven fabric, improve the subsequent puncture effect of the non-woven fabric, and thus improve the working efficiency of the needling machine 1.

[0023] A limiting slide bar 46 is fixedly connected to the bottom of the first sleeve 7 , and a limiting slide groove 47 used in conjunction with the limiting slide bar 46 is provided on the top of the support frame 2 .

[0024] In this embodiment, it is taken into consideration that a limiting slide bar 46 and a limiting slide groove 47 are provided so that when the cylinder 18 pushes the first sleeve 7 and other structures to move, they 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.

[0025] Embodiment 2: On the basis of the first embodiment, the tension adjustment mechanism in this embodiment can increase the tension of the non-woven fabric by adjusting the height of the tension roller when the non-woven fabric is wrinkled due to insufficient tension, thereby improving the subsequent non-woven fabric puncture. However, considering that if the wrinkles in the transverse part of the non-woven fabric cannot disappear due to the tension adjustment, it will still affect the effect of subsequent puncture. The transmission mechanism in this application includes a motor 20 fixedly mounted on the top of the transmission housing 9, the output end of the motor 20 penetrates into the transmission housing 9, and is fixedly connected to a first bevel gear 21, both sides of the first bevel gear 21 are meshedly connected to the second bevel gear 22, and the two sides of the second bevel gears 22 are fixedly connected to the sides away from each other. A screw rod 23, one end of the screw rod 23 is rotatably connected to the inner wall of the transmission housing 9 through a bearing, and a sliding block 24 is transmission-connected to the surface of the screw rod 23, and a second sleeve 25 is fixedly connected to one side of the smoothing roller 10, and a second sleeve 26 is slidably connected to the inner wall of the second sleeve 25, and the top of the second sleeve 26 is fixedly connected to the bottom of the sliding block 24, and an adjustment mechanism is provided on one side of the second sleeve 25; An electric push rod 27 is fixedly installed inside the first sleeve 7, and the output end of the electric push rod 27 is fixedly connected to the bottom of the second sleeve rod 26. First touch sensors 28 used in conjunction with the sliding block 24 are fixedly connected to both sides of the inner wall of the transmission housing 9, and two second touch sensors 29 are fixedly connected to the bottom of the inner wall of the transmission housing 9.

[0026] In this embodiment, by setting a transmission mechanism, when the image collector 19 captures the wrinkle pattern, the built-in PLC module of the controller 4 will also start the motor 20, such as Fig. 9As shown, when the motor 20 is started, it will drive the first bevel gear 21 to rotate, and the first bevel gear 21 will drive the second bevel gear 22 and the screw rod 23 to rotate around the bearing. When the screw rod 23 rotates, the two sliding blocks 24 will first move to the side away from each other, and at the same time drive the second sleeve rod 26 and the second sleeve 25 to move, and the two smoothing rollers 10 will also move to the side away from each other with the second sleeve 25. The two smoothing rollers 10 move to both sides respectively, which will smooth the wrinkles on the surface of the non-woven fabric. When the sliding block 24 moves to contact with the first touch sensor 28, the first touch sensor 28 will transmit a signal to the controller 4, and the built-in PLC module of the controller 4 will start the electric push rod 27, and the electric push rod 27 will push the first set of rods 8 to move upward, thereby driving the transmission housing 9 and other structures upward. At this time, the two sliding blocks 24 will just move to the side close to each other under the transmission of the screw rod 23. At the same time, the smoothing roller 10 does not contact the non-woven fabric during the movement. When the sliding block 24 moves to contact with 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 start the electric push rod 27 again, driving the first set of rods 8 to move downward, thereby making the smoothing roller 10 contact with the upper surface of the non-woven fabric, and the cycle is repeated in sequence. The smoothing roller 10 moves in a hole-shaped trajectory to smooth and wrinkle the non-woven fabric, which can effectively remove wrinkles on the surface of the fabric and improve the subsequent puncture effect. It should be noted that; Fig. 9 S1 is the moving track of the electric push rod 27 after the sliding block 24 touches the first touch sensor 28, and S2 is the moving track of the sliding block 24 in the current state; S3 is the moving track of the electric push rod 27 when the sliding block 24 touches the second touch sensor 29, and S4 is the moving track of the sliding block 24 in the current state.

[0027] The adjustment mechanism includes a hand screw 43 threadedly connected to one side of the second sleeve 25, a threaded hole 44 for use with the hand screw 43 is opened on one side of the second sleeve 25, and a positioning hole 45 for use with the hand screw 43 is opened on one side of the second sleeve rod 26. The number of the positioning holes 45 is several.

[0028] In this embodiment, taking into account the different thicknesses of the non-woven fabrics, it is necessary to adjust the thickness of the smoothing roller 10 in advance according to the thickness of the non-woven fabrics. Therefore, by providing an adjustment mechanism, the hand screw 43 can be turned to make the hand screw 43 leave the interior of the positioning hole 45. 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 26. After reaching the appropriate position, the hand screw 43 is turned in the reverse direction to make one end of the hand screw 43 enter the corresponding positioning hole 45, thereby completing the adjustment of the height of the smoothing roller 10.

[0029] A protective ring 48 is fixedly connected to the surface of the smoothing roller 10 , and the material of the protective ring 48 is rubber.

[0030] In this embodiment, the protective ring 48 is provided to play a protective role and prevent the smoothing roller 10 from being in hard contact with the non-woven fabric and causing severe wear.

[0031] Embodiment three: On the basis of the second embodiment, in this embodiment, the wrinkles on the non-woven fabric can be smoothed by the smoothing roller 10, but considering that after the wrinkles on the non-woven fabric are smoothed, the wrinkles are stretched out, and the tension of the non-woven fabric itself will decrease, thereby affecting the subsequent puncture effect, the present application also includes a booster mechanism, which is fixedly arranged on one side of the first set of rods 8; The boost mechanism includes an air collecting box 30 fixedly connected to one side of the first sleeve rod 8, the top of the air collecting box 30 is fixedly connected to an air intake pipe 31 through a first one-way valve, one side of the air collecting box 30 is fixedly connected to a transmission pipe 32 through a second one-way valve, and one end of the transmission pipe 32 is fixedly connected to the bottom of the matching box 14; A second piston plate 33 is fixedly connected to the inner wall of the air collecting 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 passes through one side of the first set of rods 8, and is fixedly connected to an extrusion block 36, the extrusion block 36 is opposite to the second set of rods 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 collecting box 30.

[0032] In this embodiment, a boosting mechanism is provided, so that when the sliding block 24 moves toward the side close to the air collecting box 30, the sliding block 24 will drive the second set of rods 26 to contact the extrusion block 36. The extrusion block 36 is squeezed and drives the traction rod 35, the second push block 34 and the second piston plate 33 to move toward the side away from the second set of rods 26. When the second piston plate 33 moves, it squeezes the air in the air collecting box 30, so that the air in the air collecting box 30 enters the inside of the matching box 14 through the transmission pipe 32. When the second set of rods 26 moves to a point where it is not in contact with the extrusion block 36, the tension spring 3 The pulling force generated by 7 will drive the second push block 34 and the second piston plate 33 to reset. At this time, the air collecting box 30 is under negative pressure, and the gas will enter the interior of the air collecting box 30 through the air inlet pipe 31, and circulate in sequence, and intermittently inject gas into the matching box 14. Under the pressure of the gas, the first piston plate 15, the first push block 16, the connecting block 17, the linkage block 13, the second sleeve 25 and other structures will intermittently move upward, thereby driving the positioning block 6 and the tensioning roller 5 to move upward intermittently, and by making the tensioning roller 5 always against the bottom of the non-woven fabric, the tension of the non-woven fabric is increased; It should be noted that the first one-way valve is a valve that can only allow air to enter the air collecting box 30 , and the second one-way valve is a valve that can only allow air to enter the air collecting box 30 .

[0033] A pressure relief pipe 38 is fixedly connected to one side of the matching box 14 , and a one-way pressure valve 39 is fixedly installed on the surface of the pressure relief pipe 38 .

[0034] In this embodiment, it is considered that if gas is continuously injected into the matching box 14, causing the tensioning roller 5 to rise intermittently, excessive tension of the non-woven fabric may occur. Therefore, by providing a pressure relief pipe 38 and a one-way pressure valve 39, when the upper surface of the tensioning roller 5 contacts the bottom of the non-woven fabric, injecting gas into the matching box 14 will compress the gas. When the air pressure exceeds the limit of the one-way pressure valve 39, the gas will be intermittently ejected from the pressure relief pipe 38, making it impossible for the tensioning roller 5 to rise, thereby avoiding excessive tension of the non-woven fabric.

[0035] An exhaust pipe 40 is fixedly connected to the bottom of the coordination box 14 , and a solenoid valve 41 is fixedly installed on the surface of the exhaust pipe 40 .

[0036] In this embodiment, by providing the exhaust pipe 40 and the electromagnetic valve 41, after the non-woven fabric is processed, the electromagnetic valve 41 can be activated to exhaust all the gas in the matching box 14 for subsequent reuse.

[0037] Two springs 42 are fixedly connected to the top of the first pushing block 16 , and the tops of the springs 42 are fixedly connected to the inner wall of the matching box 14 .

[0038] In this embodiment, a spring 42 is provided so that when the gas in the matching 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, thereby resetting the first push block 16 and the first piston plate 15 and increasing the rate at which the gas in the matching box 14 is discharged.

[0039] The working principle and use process of the present invention are as follows: when the tension of the nonwoven fabric is insufficient during the conveying process, the image collector 19 will capture the wrinkles of the nonwoven fabric caused by the insufficient tension 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, and the cylinder 18 will push the matching box 14 to move upward. The first piston plate 15, the first push block 16 and the connecting block 17 in the matching 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, and the positioning block 6 and the tensioning roller 5 will also move upward synchronously with the first sleeve 7. The upper surface of the tensioning roller 5 is pressed against the bottom of the nonwoven fabric, so as to realize the function of intelligently adjusting the tension of the nonwoven fabric, improve the effect of subsequent nonwoven fabric puncture, and thus improve the working efficiency of the acupuncture machine 1; When the image collector 19 captures the wrinkled pattern, the built-in PLC module of the controller 4 will also start the motor 20. As Fig. 9 shown, when the motor 20 starts, it will drive the first bevel gear 21 to rotate. The first bevel gear 21 will drive 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 will first move towards the side away from each other, and at the same time drive the second sleeve rod 26 and the second sleeve 25 to move. The two flattening rollers 10 will also move towards the side away from each other with the second sleeve 25. The two flattening rollers 10 move towards both sides respectively, which will flatten 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 will transmit a signal to the controller 4. The built-in PLC module of the controller 4 will start the electric push rod 27, and the electric push rod 27 will push the first sleeve rod 8 upwards, thereby driving structures such as the transmission housing 9 upwards. At this time, the two sliding blocks 24 will just move towards the side close to each other under the drive of the lead screw 23, and at the same time, the flattening rollers 10 will not contact the non-woven fabric during the 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 start the electric push rod 27 again, driving the first sleeve rod 8 to move downwards, so that the flattening rollers 10 contact the upper surface of the non-woven fabric. In this way, in turn, the flattening rollers 10 move in a mouth-shaped trajectory to flatten and remove wrinkles from the non-woven fabric, which can effectively remove the wrinkles on the fabric surface and improve the subsequent puncture effect; While the sliding block 24 moves towards the side close to the air collecting box 30, the sliding block 24 will drive the second sleeve rod 26 to contact the extrusion block 36. The extrusion block 36 is extruded and will drive the traction rod 35, the second push block 34 and the second piston plate 33 to move towards the side away from the second sleeve rod 26. While the second piston plate 33 moves, it will squeeze the air in the air collecting box 30, so that the air in the air collecting box 30 enters the inside of the matching box 14 through the transmission pipe 32. When the second sleeve rod 26 moves to not contact the extrusion block 36, the pulling force generated by the tension spring 37 will drive the second push block 34 and the second piston plate 33 to reset. At this time, the air collecting box 30 is in a negative pressure state, and the gas will enter the inside of the air collecting box 30 through the air inlet pipe 31. In this way, in turn, gas is intermittently injected into the matching box 14. Under the extrusion of the gas, structures such as 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 upwards intermittently, thereby driving the positioning block 6 and the tensioning roller 5 to move upwards intermittently. By making the tensioning roller 5 always press against the bottom of the non-woven fabric, the tension of the non-woven fabric is improved.
