Description

Technical Field

[0001] This invention relates to the field of textile padding technology, specifically to an adjustable double-sided padding treatment device for textiles. Background Technology

[0002] Double-sided padding is a common dyeing and finishing process for textiles. It is mainly used to uniformly apply dyes, auxiliaries, or functional finishing agents to both sides of the fabric, enabling the textile to possess multiple properties and meet complex application requirements. During the padding process, in order to maintain the stability of the fabric's running trajectory, the fabric speed, i.e., the machine speed, needs to be related to the fabric tension. That is, for every 10m / min increase in machine speed, the fabric tension needs to increase by 5%. At the same time, the increase in machine speed will reduce the time for the fabric to pass through the rollers, resulting in insufficient padding time, which will increase the liquid carryover rate. This makes it easy for migration to occur during pre-drying, resulting in color difference or stripes on the front and back sides. At the same time, more moisture needs to be evaporated, increasing energy consumption.

[0003] To address the impact of increased vehicle speed, the pressure of the rollers needs to be increased. Specifically, for every 10 m / min increase in vehicle speed, the roller pressure needs to be increased by 5-8%. The existing solution is to determine the vehicle speed using a speed sensor and then adjust the torque of the tension roller and the pressure of the rollers according to the relationship using a PLC program.

[0004] A search revealed that Chinese patent application CN116988243B discloses a dyeing and finishing padding equipment. While this avoids dust on the fabric and improves the padding effect, it cannot automatically adjust the fabric tension according to the machine speed. Existing methods require numerous electrical components and PLC program control, increasing costs, causing wiring difficulties, and increasing the risk of component damage. Furthermore, real-time speed measurement and calculation of various values ​​are necessary, hindering rapid operation and adding to the complexity of measurement and calculation. When the machine speed changes, the spacing between the rollers needs to adapt to the adjustment of the roller pressure, but the linkage between the upper and lower rollers cannot be adjusted accordingly. This prevents the upper and lower rollers from meeting the requirement of running in opposite directions at the same speed, necessitating separate control of the upper and lower rollers. This increases the use of motors and requires synchronous start-stop, potentially affecting the padding quality of textiles. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable double-sided padding treatment device for textiles.

[0009] As a further aspect of the present invention: the gas guide tube is fixedly sleeved with the shell, the positioning ring is fixed to the explosion-proof glass jar by fastening bolts, and the first one-way valve discharges the gas from the top of the explosion-proof glass jar.

[0010] As a further embodiment of the present invention: the proportional valve is fixedly connected to the bottom surface of the housing, and the input end of the proportional valve is connected to an external pressure pipe, and the main pipe is fixedly sleeved to the bottom wall of the housing.

[0011] As a further embodiment of the present invention: a through hole is provided on the side wall of the housing, a sleeve is fixedly connected to the side wall of the bracket, a second vortex fan is fixedly connected to the end face of the lower pressure roller, the second vortex fan is sleeved with the sleeve, and one end of a connecting pipe is connected to the side wall of the sleeve, the other end of the connecting pipe is connected to a telescopic rod, a movable disk is fixedly connected to the output end of the telescopic rod, a multi-faceted ring is fitted on the central axis of the movable disk, a top plate is fitted on the outer surface of the multi-faceted ring, a compression spring is fixedly connected between the top plate and the movable disk, and a stop rod is fixedly connected to the end face of the top plate, a stop block is contacted on the outer surface of the stop rod, a planetary carrier is fixedly connected to the side wall of the stop block, a planetary gear is rotatably connected to the end face of the planetary carrier, a gear ring and a sun gear are meshed on the outer surface of the planetary gear, and a rotating rod is fixedly connected to the central axis of the sun gear.

[0012] As a further embodiment of the present invention: the end face of the gear ring is fixedly connected to the end face of the upper pressure roller, the rotating rod is rotatably connected to the side wall of the cavity, the outer surface of the planetary carrier is slidably connected to the side wall of the cavity, and the gear ring is rotatably sleeved with the cavity.

[0013] As a further embodiment of the present invention: the connecting pipe is fixedly sleeved with the housing, the telescopic rod is fixedly connected with the side wall of the cavity, and a second one-way valve is installed on the end face of the telescopic rod, and the second one-way valve discharges gas from one end of the connecting pipe, the polygonal ring is fixedly connected with the side wall of the cavity, and the polygonal ring is sleeved with the rotating rod.

[0014] Compared with the prior art, the beneficial effects of the present invention, using the above technical solution, are as follows: This invention accelerates the rotational speed of the first transmission chain via a drive shaft, which in turn accelerates the rotational speed of the second transmission chain and the upper pressure roller. At this time, the driving gear on the second transmission chain drives the driven gear to rotate, causing the lower pressure roller on the driven gear to rotate faster. As the lower pressure roller accelerates, the second turbine fan on the lower pressure roller increases its blowing efficiency, increasing the flow rate of gas entering the telescopic rod through the connecting pipe. This makes the efficiency of air entering the telescopic rod much greater than the efficiency of air exiting through the second one-way valve, increasing the air pressure at the end of the telescopic rod. This causes the telescopic rod to extend, pushing the moving disc to translate and shortening the gap between the moving disc and the top disc. This, in turn, increases the elasticity of the compression spring. Based on the above principle, this indirectly increases the torque of the upper pressure roller, thus increasing the tension of the textile. Through testing and calibration, the increase in textile tension satisfies the formula... Where T0 is the initial tension, V0 is the initial vehicle speed, and V is the current vehicle speed, the tension increases by 5% for every 10m / min increase in vehicle speed, achieving the purpose of automatically correcting the fabric pressure, so that the fabric can maintain the stability of the running trajectory, without the need for a large number of electrical components or PLC program to participate in the control, which not only reduces the cost input, but also avoids the problems of difficult wiring and easy damage to electrical components.

[0015] This invention utilizes a first turbofan to accelerate rotation, increasing the blowing efficiency of the gas-gathering chamber. This increases the flow rate of gas entering the explosion-proof glass jar through the gas guide pipe, making the efficiency of air entering the top of the explosion-proof glass jar significantly greater than the efficiency of air exiting through the first one-way valve. This results in increased air pressure at the top of the explosion-proof glass jar, causing the piston to descend and creating a height difference between the piston and the positioning ring. At this point, air is supplied to the proportional valve through an external pressurization pipe, maintaining a fixed airflow ratio between the main pipe and the branch pipes. As air is injected into the explosion-proof glass jar through the branch pipes, the air pressure at the bottom of the jar increases, causing the piston to rise and return to alignment with the positioning ring. Air injection then stops. Simultaneously, the main pipe injects air to pressurize the pressure push rod, which, through a support, increases the pressure on the lower pressure roller, thereby adjusting the roller pressure to satisfy the formula... Where k is the correction coefficient, P is the roll pressure, and P0 is the initial roll pressure, the roll pressure increases by 5-8% for every 10m / min increase in speed. The roll pressure can be automatically adjusted according to the speed, further satisfying the above functions. At the same time, there is no need to measure the speed in real time or calculate various values ​​based on the speed, which is beneficial for rapid effect and avoids the trouble of measurement and calculation.

[0016] This invention uses a bracket on the lower pressure roller to lift the bottom of the second transmission chain, causing the second transmission chain to loosen. This reduces the constraint of the second transmission chain on the adjusting sprocket, thereby reducing the restriction of the adjusting spring on the slider on the adjusting sprocket. The adjusting spring then contracts, and the slider and adjusting sprocket re-tighten the second transmission chain, ensuring that the second transmission chain is always taut. This allows for continuous transmission, unaffected by the adjustment of the lower pressure roller. It also allows the upper and lower pressure rollers to meet the requirement of running in opposite directions at the same speed. There is no need to control the upper and lower pressure rollers separately; only one motor is needed to ensure synchronous start and stop while guaranteeing the impregnation quality of the textile.

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1, please refer to Figures 1-4 , Figure 6 and Figure 9This invention provides a technical solution: an adjustable double-sided impregnation treatment device for textiles, comprising a housing 1, a guide roller 2 and a collecting roller 3 rotatably connected to the side wall of the housing 1, a cavity 4 formed in the side wall of the housing 1, and a motor 5 mounted on the side wall of the housing 1. One end of a transmission shaft 6 is fixedly connected to the output end of the motor 5, and a first transmission chain 7 is fixedly connected to the other end of the transmission shaft 6. Both ends of the first transmission chain 7 are fixedly connected to rotating shafts 8, and a second transmission chain 9 is fixedly connected to the end face of the rotating shaft 8. One end of the first transmission chain 9 is fixedly connected to an upper pressure roller 16, and the other end of the second transmission chain 9 is fixedly connected to a drive gear 13. An adjusting sprocket 10 is meshed on the side wall of the second transmission chain 9. A slider 11 is hinged to both ends of the adjusting sprocket 10. An adjusting spring 12 is fixed between the slider 11 and the cavity 4. A driven gear 14 is meshed on the outer surface of the drive gear 13. A lower pressure roller 15 is fixedly connected to the end face of the driven gear 14. A bracket 17 is rotatably sleeved at both ends of the lower pressure roller 15. A pressure push rod 18 is installed on the bottom surface of the bracket 17.

[0021] Please see Figure 2 , Figure 3 and Figure 9 The drive shaft 6 is rotatably sleeved with the housing 1, and the drive shaft 6 extends into the cavity 4. The first drive chain 7 and the second drive chain 9 are both located in the cavity 4. The slider 11 is slidably sleeved with the cavity 4. The rotating shaft 8 is rotatably sleeved with the housing 1. The bracket 17 is slidably connected to the inner side wall of the housing 1. The bottom end of the second drive chain 9 is rotatably connected to the side wall of the bracket 17. The driven gear 14 is rotatably connected to the side wall of the bracket 17.

[0022] Specifically, during the accelerated weaving process, the motor 5 accelerates the rotation speed of the first transmission chain 7 via the transmission shaft 6, causing the rotating shaft 8 on the first transmission chain 7 to accelerate the rotation speed of the second transmission chain 9 and the upper pressure roller 16. At this time, the driving gear 13 on the second transmission chain 9 drives the driven gear 14 to rotate, causing the lower pressure roller 15 on the driven gear 14 to accelerate. As the lower pressure roller 15 accelerates, the second turbine fan 31 on the lower pressure roller 15 increases the blowing efficiency, increasing the flow rate of gas entering the telescopic rod 33 through the connecting pipe 32. This makes the efficiency of air entering the telescopic rod 33 much greater than the efficiency of air discharge from the second one-way valve, causing the air pressure at the end of the telescopic rod 33 to increase. This causes the telescopic rod 33 to extend, pushing the moving disk 34 to translate and shortening the gap between the moving disk 34 and the top disk 36. This, in turn, increases the elasticity of the compression spring 37. Based on the above principle, this indirectly increases the torque of the upper pressure roller 16, thereby increasing the tension of the textile. Through testing and calibration, the increase in textile tension satisfies the formula... Where T0 is the initial tension, V0 is the initial vehicle speed, and V is the current vehicle speed, the tension increases by 5% for every 10m / min increase in vehicle speed, achieving the purpose of automatically correcting the fabric pressure, so that the fabric can maintain the stability of the running trajectory, without the need for a large number of electrical components or PLC program to participate in the control, which not only reduces the cost input, but also avoids the problems of difficult wiring and easy damage to electrical components.

[0023] Example 2, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 This invention provides a technical solution: an adjustable double-sided impregnation treatment device for textiles, wherein a gas-gathering chamber 19 is provided in the side wall of the housing 1, a first turbine fan 20 is fixedly connected to the end of the first transmission chain 7, the first turbine fan 20 is sleeved with the gas-gathering chamber 19, and one end of the gas guide pipe 21 is connected to the side wall of the gas-gathering chamber 19, the other end of the gas guide pipe 21 is connected to an explosion-proof glass jar 22, a first one-way valve 23 is installed on the top wall of the explosion-proof glass jar 22, and a piston 24 is slidably sleeved inside the explosion-proof glass jar 22, a positioning ring 25 is sleeved on the outer surface of the explosion-proof glass jar 22, and one end of the branch pipe 26 is connected to the bottom end of the explosion-proof glass jar 22, the other end of the branch pipe 26 is connected to a proportional valve 27, one end of the main pipe 28 is connected to the output end of the proportional valve 27, and the other end of the main pipe 28 is connected to a pressure push rod 18.

[0024] Please see Figure 2 and Figure 6 The gas duct 21 is fixedly sleeved with the shell 1, and the positioning ring 25 is fixed to the explosion-proof glass jar 22 by fastening bolts. The first one-way valve 23 discharges the gas from the top of the explosion-proof glass jar 22.

[0025] Please see Figure 2 and Figure 6 The proportional valve 27 is fixedly connected to the bottom surface of the housing 1, and the input end of the proportional valve 27 is connected to the external pressure pipe. The main pipe 28 is fixedly sleeved to the bottom wall of the housing 1.

[0026] Specifically, as the rotational speed of the first transmission chain 7 and the upper pressure roller 16 increases, the first turbine fan 20 at the end of the first transmission chain 7 accelerates its rotation, increasing the blowing efficiency of the gas-gathering chamber 19. This increases the flow rate of gas entering the explosion-proof glass jar 22 through the air guide pipe 21, making the efficiency of air entering the top of the explosion-proof glass jar 22 much greater than the efficiency of air exiting through the first one-way valve 23. This increases the air pressure at the top of the explosion-proof glass jar 22, causing the piston 24 to descend. This creates a height difference between the piston 24 and the positioning ring 25. At this point, the external... Air is supplied through the pressure pipe to the proportional valve 27, maintaining a fixed airflow ratio between the main pipe 28 and the branch pipe 26. As air is injected into the explosion-proof glass jar 22 through the branch pipe 26, the air pressure at the bottom of the explosion-proof glass jar 22 increases, causing the piston 24 to rise and return to alignment with the positioning ring 25. At this point, air injection stops. Simultaneously, air is injected into the pressure push rod 18 through the main pipe 28, increasing the pressure of the lower pressure roller 15 via the bracket 17. This adjusts the roller pressure so that the adjusted roller pressure value satisfies the formula... Where k is the correction coefficient, P is the roll pressure, and P0 is the initial roll pressure, the roll pressure increases by 5-8% for every 10m / min increase in speed. The roll pressure can be automatically adjusted according to the speed, further satisfying the above functions. At the same time, there is no need to measure the speed in real time or calculate various values ​​based on the speed, which is beneficial for rapid effect and avoids the trouble of measurement and calculation.

[0027] Example 3, please refer to Figure 2 , Figure 5 , Figure 7 and Figure 8 This invention provides a technical solution: an adjustable double-sided impregnation treatment device for textiles, wherein a through hole 29 is provided on the side wall of the housing 1, a sleeve 30 is fixedly connected to the side wall of the support 17, a second vortex fan 31 is fixedly connected to the end face of the lower pressure roller 15, the second vortex fan 31 is sleeved with the sleeve 30, and one end of a connecting pipe 32 is connected to the side wall of the sleeve 30, the other end of the connecting pipe 32 is connected to a telescopic rod 33, a movable disk 34 is fixedly connected to the output end of the telescopic rod 33, and a central axis of the movable disk 34 is embedded in... A multi-faceted ring 35 is fitted together, and a top plate 36 is fitted onto the outer surface of the multi-faceted ring 35. A compression spring 37 is fixed between the top plate 36 and the movable plate 34. A stop bar 38 is fixed to the end face of the top plate 36. A stop block 39 is connected to the outer surface of the stop bar 38. A planet carrier 40 is fixed to the side wall of the stop block 39. A planet gear 41 is rotatably connected to the end face of the planet carrier 40. A gear ring 44 and a sun gear 42 are meshed on the outer surface of the planet gear 41. A rotating rod 43 is fixed to the central axis of the sun gear 42.

[0028] Please see Figure 5The end face of the gear ring 44 is fixedly connected to the end face of the upper pressure roller 16, the rotating rod 43 is rotatably connected to the side wall of the cavity 4, the outer surface of the planetary carrier 40 is slidably connected to the side wall of the cavity 4, and the gear ring 44 is rotatably sleeved with the cavity 4.

[0029] Please see Figure 5 and Figure 7 The connecting pipe 32 is fixedly sleeved with the housing 1, the telescopic rod 33 is fixedly connected with the side wall of the cavity 4, and a second one-way valve is installed on the end face of the telescopic rod 33. The second one-way valve discharges the gas from one end of the connecting pipe 32. The polygonal ring 35 is fixedly connected with the side wall of the cavity 4, and the polygonal ring 35 is sleeved with the rotating rod 43.

[0030] Specifically, during the adjustment of the roller pressure, the spacing between the rollers needs to be adaptively changed. That is, when the pressure increases, the lower roller 15 rises, causing the bracket 17 on the lower roller 15 to drive the bottom end of the second transmission chain 9 to rise, thus loosening the second transmission chain 9. This reduces the constraint of the second transmission chain 9 on the adjusting sprocket 10, reduces the restriction of the slider 11 on the adjusting sprocket 10 on the adjusting spring 12, causes the adjusting spring 12 to contract, and re-tightens the second transmission chain 9 through the slider 11 and the adjusting sprocket 10, ensuring that the second transmission chain 9 is always taut and can continuously transmit power without being affected by the adjustment of the lower roller 15. This allows the upper roller 16 and the lower roller 15 to meet the requirement of running in opposite directions at the same speed. There is no need to control the upper roller 16 and the lower roller 15 separately. Only one motor 5 is needed to ensure synchronous start and stop while ensuring the impregnation quality of the textile.

[0031] The working principle and usage process of this invention are as follows: When textiles need to be impregnated, corresponding functional coatings are sprayed onto both sides of the textiles. The textiles are then introduced into the housing 1, allowing them to pass sequentially through the upper pressure roller 16, the lower pressure roller 15, and the guide roller 2. Finally, they are dried and curled onto the collecting roller 3. During this process, the height of the upper pressure roller 16 is fixed. The support 17 and the lower pressure roller 15 are raised by the pressure push rod 18, allowing the upper pressure roller 16 to cooperate with the lower pressure roller 15 in rolling the textiles. This ensures that the liquid retention rate of the textiles is within the range of 60-80%. Simultaneously, the moving disc... The compression spring 37 between the sun gear 34 and the top plate 36 contracts, causing the compression spring 37 to exert a thrust on the top plate 36. This causes the top plate 36, guided by the polygonal ring 35, to tend to move towards the planet carrier 40. This indirectly increases the force on the stop lever 38 on the top plate 36 that overcomes the spring force and moves backward. The rotation of the planet carrier 40 requires the stop block 39 on it to push the stop lever 38 backward. Therefore, the planet carrier 40 generates a limiting torque. In the planet gear set 41, the torque relationship between the sun gear 42, the ring gear 44, and the planet carrier 40 follows a fixed proportional distribution, and the relationship is as follows: ,in T represents the gear ratio between the ring gear 44 and the sun gear 42. S The sun gear has a torque of 42, T RFor the gear ring, the torque is 44, T C The torque of the planetary carrier 40 is thus generated by the upper pressure roller 16, which is fixed to the gear ring 44, and the tension formula of the textile is... Where T is the fabric tension, M is the roller torque, and r is the roller radius, thus tension can be applied to the textile. When it is necessary to accelerate the weaving speed of the textile, the motor 5 accelerates the rotation speed of the first transmission chain 7 via the transmission shaft 6. This causes the rotating shaft 8 on the first transmission chain 7 to accelerate the rotation speed of the second transmission chain 9 and the upper pressure roller 16. At this time, the driving gear 13 on the second transmission chain 9 drives the driven gear 14 to rotate, causing the lower pressure roller 15 on the driven gear 14 to accelerate. As the lower pressure roller 15 accelerates, the second turbine fan 31 on the lower pressure roller 15 increases the blowing efficiency, increasing the flow rate of gas entering the telescopic rod 33 through the connecting pipe 32. This makes the efficiency of air entering the telescopic rod 33 much greater than the efficiency of air discharge from the second one-way valve, causing the air pressure at the end of the telescopic rod 33 to increase. This causes the telescopic rod 33 to extend, pushing the moving disk 34 to translate and shortening the gap between the moving disk 34 and the top disk 36. This, in turn, increases the elastic force of the compression spring 37. Based on the above principle, this indirectly increases the torque of the upper pressure roller 16, thereby increasing the tension of the textile. Through testing and calibration, the increase in textile tension satisfies the formula... Where T0 is the initial tension, V0 is the initial vehicle speed, and V is the current vehicle speed. This means that for every 10m / min increase in vehicle speed, the tension increases by 5%, achieving the purpose of automatically correcting the fabric pressure. This allows the fabric to maintain a stable running trajectory without the need for a large number of electrical components or PLC program control. This not only reduces the cost but also avoids the problems of difficult wiring and easy damage to electrical components. It should be further explained that as the spring force of the compression spring 37 increases, the force of the compression spring 37 in resisting the movement of the moving disc 34 increases, which indirectly increases the elongation resistance of the telescopic rod 33 until the gas pressure at the end of the telescopic rod 33 is balanced with the elongation resistance. At this time, the rotational speed of the upper pressure roller 16 returns to a constant position, and the system is rebalanced. When the rotational speed of the first transmission chain 7 and the upper pressure roller 16 increases, the first turbine fan 20 at the end of the first transmission chain 7 accelerates its rotation, increasing the blowing efficiency of the gas-gathering chamber 19. This increases the flow rate of gas entering the explosion-proof glass jar 22 through the air guide pipe 21, making the efficiency of air entering the top of the explosion-proof glass jar 22 much greater than the efficiency of air exiting through the first one-way valve 23. This increases the air pressure at the top of the explosion-proof glass jar 22, causing the piston 24 to descend and creating a height difference between the piston 24 and the positioning ring 25. At this point, external pressure is applied... Air is supplied to the proportional valve 27 through the pipe, maintaining a fixed airflow ratio between the main pipe 28 and the branch pipe 26. As air is injected into the explosion-proof glass container 22 through the branch pipe 26, the air pressure at the bottom of the explosion-proof glass container 22 increases, thereby causing the piston 24 to rise and return to alignment with the positioning ring 25. At this point, air injection stops. Simultaneously, air is injected into the pressure push rod 18 through the main pipe 28, increasing the pressure of the lower pressure roller 15 via the bracket 17. This adjusts the roller pressure so that the adjusted roller pressure value satisfies the formula. Where k is the correction coefficient, P is the roll pressure, and P0 is the initial roll pressure, so that for every 10m / min increase in speed, the roll pressure increases by 5~8%. The roll pressure can be automatically adjusted according to the speed, which further satisfies the above functions. At the same time, there is no need to measure the speed in real time or calculate various values ​​based on the speed, which is conducive to rapid effect and avoids the trouble of measurement and calculation. As the pressure of the rollers is adjusted, the spacing between the rollers needs to change accordingly. That is, when the pressure increases, the lower roller 15 rises, causing the bracket 17 on the lower roller 15 to drive the bottom end of the second transmission chain 9 to rise, thus loosening the second transmission chain 9. This reduces the constraint of the second transmission chain 9 on the adjusting sprocket 10, and reduces the restriction of the slider 11 on the adjusting sprocket 10 on the adjusting spring 12. This causes the adjusting spring 12 to contract, and through the slider 11 and the adjusting sprocket 10, the second transmission chain 9 is tightened again, ensuring that the second transmission chain 9 is always taut and can continue to transmit power without being affected by the adjustment of the lower roller 15. This allows the upper roller 16 and the lower roller 15 to meet the requirement of running in opposite directions at the same speed. There is no need to control the upper roller 16 and the lower roller 15 separately. Only one motor 5 is needed to ensure synchronous start and stop while ensuring the quality of textile impregnation and completing the operation.
