Description

Technical Field

[0001] The invention relates to the technical field of napping machine equipment, in particular to a napping machine for fabric finishing. Background Art

[0002] In the textile industry, the finishing process of fabrics plays a vital role in improving fabric quality, enhancing fabric functions and beautifying appearance. As a common finishing process, raising the napping layer on the surface of the fabric forms a uniform and delicate layer of nap through a specific mechanical action, which not only increases the softness and warmth of the fabric, but also gives the fabric a unique touch and visual effect. With the increasing requirements of consumers for the quality of textiles, how to achieve precise control and flexible adjustment of the raising effect of fabrics has become one of the key directions of technological innovation in the textile industry.

[0003] The traditional device has the following shortcomings: Existing fabric raising machines usually include a feeding system, a raising system and a winding system. The core components of the raising system are a large drum and needle rollers distributed on the outside of the large drum. The needle rollers are in contact with the fabric. During the raising process, the needle rollers not only revolve with the large drum but also rotate on their own, forming a differential motion. The fabric is coated on the needle surface of the needle cloth roller. By adjusting the speed between the large drum, the needle roller and the fabric, the fabric can be combed or raised. The length of the needle on the needle roller of the traditional raising machine is fixed, which means that once the needle roller is manufactured, the thickness of the raising is basically determined. In the actual production process, it is often necessary to adjust the thickness of the raising according to different fabric materials, thicknesses and customer needs, but the fixed-length needle rollers are difficult to meet this demand. If the operator needs to change the raising thickness, it is usually necessary to replace the entire needle roller, which is not only cumbersome to operate and increase production costs, but frequent replacement may also lead to low production efficiency and cannot meet the requirements of the modern textile industry to respond quickly to market changes.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0019] See also Figure 1-12 As shown, the present invention provides a technical solution of a napping machine for fabric finishing: a napping machine for fabric finishing, comprising a shell 1, a driving roller group 2 composed of a plurality of rollers for driving fabric feeding is installed on the inner side of the shell 1, the driving roller group 2 is composed of a tension roller, a cloth guide roller and a hair removal roller, a driving shaft 3 is horizontally installed on the inner side of the shell 1, a motor of the driving shaft 3 is installed on the outer side of the shell 1 and penetrates the shell 1 and is connected to the driving shaft 3, a large roller 4 is fixedly installed on the driving shaft 3, mounting plates 5 are fixedly installed at both ends of the large roller 4, a plurality of napping roller groups 6 with adjustable napping thickness are circumferentially installed on the mounting plate 5 with the driving shaft 3 as the axis, and an adjusting component 7 and a controller 8 matching the napping roller group 6 are also installed on the shell 1; The pile roller group 6 includes a mounting shaft 601, an inner cover 604, an electromagnetic ring 607 and a return spring 608. The mounting shaft 601 is connected to the mounting plate 5 and is located on the outside of the large drum 4 in a circular rotation with the drive shaft 3 as the axis. A power member 602 for driving all the mounting shafts 601 to rotate is installed on the outside of the mounting plate 5. The power member 602 provides the power to drive the mounting shaft 601 to rotate. The power member 602 can be driven by several motors or with a pulley to drive the mounting shaft 601 to rotate. An outer cover 603 is sleeved on the outer side of the mounting shaft 601. The inner cover 604 is circumferentially installed on the outer side of the shaft body of the mounting shaft 601 with the mounting shaft 601 as the axis. A lifting magnetic plate 605 is slidably connected to the inner side of the inner cover 604. A plurality of pile needles 606 are arranged and installed on the lifting magnetic plate 605 at a certain interval. The pile needles 606 are made of steel wire material. The ends of the pile needles 606 pass through the inner cover 604 and the outer cover 603 to contact the fabric for fabric pile raising. The electromagnetic ring 607 is embedded in the shaft of the installation shaft 601, and is used to adjust the position of the lifting magnetic plate 605 in the inner cover 604. The return spring 608 is sleeved on the pile needle 606 and is located on the inner side of the inner cover 604. The return spring 608 is used to provide a thrust to push the lifting magnetic plate 605 toward the installation shaft 601. The number of return springs 608 can be determined according to actual use requirements. The torsion component 609 is movably installed on the inner side of the outer cover 603 to adjust the needle angle of the pile needle 606.

[0020] When the raising machine needs to perform raising finishing, the staff first sets the standard thickness of the raising, and then the controller 8 passes a constant current through the electromagnetic ring 607 through the adjustment component 7 according to the set raising thickness. After the electromagnetic ring 607 is energized, a certain repulsive force is generated on the lifting magnetic plate 605. The magnitude of the repulsive force is determined by the magnitude of the current. The constant repulsive force enables the lifting magnetic plate 605 to overcome the elastic force of the return spring 608 and drive the raising needle 606 to extend a certain distance to the outside of the outer cover 603. Since the magnitude of the current determines the displacement stroke of the raising needle 606, the raising thickness can be set.

[0021] Through the raising roller group 6, when the raising thickness requirement changes, there is no need to replace the needle roller. The repulsive force on the lifting magnetic plate 605 can be changed by adjusting the current on the electromagnetic ring 607, so that the moving stroke of the raising needle 606 can be accurately controlled, and finally the accurate adjustment of the raising thickness of the fabric is achieved, which significantly improves the operating convenience and production efficiency, reduces the production cost, and is more in line with the actual use needs of current textile enterprises.

[0022] The adjustment assembly 7 includes an upper pressing plate 701, a lifting assembly 702, a horizontal telescopic connecting rod 706, a first conductive strip 708 and a conductive assembly 710. The upper pressing plate 701 is fixedly mounted on the inner side of the shell 1 above the material discharge end. The lifting assembly 702 is symmetrically mounted on both sides of the shell 1. A lifting platform 703 is mounted on one side of the shell 1 of the lifting assembly 702. The lifting platform 703 can move up and down relative to the shell 1. A telescopic support member 704 is mounted above the lifting platform 703. The telescopic support member 704 can be a spring, a hydraulic telescopic rod or a pneumatic telescopic rod, etc. A lower pressing plate 705 matching the upper pressing plate 701 is mounted above the telescopic support member 704. The lower pressing plate 705 can move up and down relative to the shell 1. The telescopic support member 704 enables the lower pressing plate 705 to always maintain an upward thrust on the upper pressing plate 701. The horizontal telescopic link 706 is rotatably connected to the mounting frame on the upper end surface of the lifting platform 703 on one side, and the vertical telescopic link 707 is rotatably connected to one side of the lower end surface of the lower pressure plate 705, and the other end of the vertical telescopic link 707 is rotatably connected to one end of the horizontal telescopic link 706. The first conductive bar 708 is vertically fixedly installed in the through slot on one side of the lifting platform 703, and the second conductive bar 709 is slidably connected to the first conductive bar 708, and the upper end of the second conductive bar 709 is rotatably connected to one end of the horizontal telescopic link 706, and the second conductive bar 709 is connected to the controller 8 through a wire. The conductive component 710 is installed on the driving shaft 3 and the mounting plate 5 to establish a path between the electromagnetic ring 607 and the controller 8.

[0023] The external power supply is connected to the electromagnetic ring 607 through the controller 8, the first conductive strip 708, the second conductive strip 709 and the conductive component 710. Since the first conductive strip 708 is fixed, the second conductive strip 709 can slide up and down relative to the first conductive strip 708. When the second conductive strip 709 moves upward, the contact area between the two decreases and the resistance increases. Under the condition that other conditions remain unchanged, according to Ohm's law, the current passing through decreases, and the current on the electromagnetic ring 607 decreases. Conversely, when the second conductive strip 709 moves downward, the current passing through the two increases, and the current on the electromagnetic ring 607 also increases.

[0024] Before the raising machine starts working, the lifting assembly 702 is adjusted according to the standard thickness of the fabric after raising, and the initial height of the lifting platform 703 is set. The adjustment standard is that if the product thickness is normal during the raising process, the distance between the lower pressing plate 705 and the upper pressing plate 701 is the standard thickness of the fabric. At this time, the horizontal telescopic connecting rod 706 remains horizontal, and the first conductive strip 708 and the second conductive strip 709 are connected to their respective halves. Although the controller 8 sets the current required by the electromagnetic ring 607 according to the required raising thickness of the fabric, the current value can only be achieved when the horizontal telescopic connecting rod 706 is in a horizontal state. If the first conductive strip 708 and the second conductive strip 709 slide and are not connected to their respective halves, the current will also be adjusted accordingly due to the change in resistance.

[0025] During the process of raising the fabric, if the overall thickness of the fabric after processing is too thick or too thin due to the wear of the raising needle 606 or the error of the fabric thickness or other factors, the lower pressing plate 705 will correspondingly overcome the resistance of the telescopic support 704 to rise or fall due to the change in thickness. The up and down displacement of the lower pressing plate 705 is transmitted to the horizontal telescopic link 706 through the vertical telescopic link 707, thereby driving the second conductive strip 709 and the first conductive strip 708 to slide relative to each other. If the fabric thickness is too thick, the second conductive strip 709 slides upward relative to the first conductive strip 708. At this time, the current on the electromagnetic ring 607 decreases, and the repulsive force on the lifting magnetic plate 605 also decreases. The raising needle 606 will correspondingly retract a part of it into the outer cover 603, so that the thickness of the raising is reduced until the standard thickness is restored. If the fabric is too thin, the second conductive strip 709 will slide downward relative to the first conductive strip 708. At this time, the current on the electromagnetic ring 607 will increase, and the repulsive force on the lifting magnetic plate 605 will also increase. The raising needle 606 will extend out of a part of the outer cover 603 accordingly, so that the thickness of the raising will increase until the standard thickness is restored.

[0026] By adjusting component 7, the resistance between the first conductive strip 708 and the second conductive strip 709 is adjusted by utilizing the change in the distance between the upper pressing plate 701 and the lower pressing plate 705 when the fabric thickness deviates, and the overall effect is amplified by the lever cooperation of the horizontal telescopic link 706 and the vertical telescopic link 707. Finally, combined with Ohm's law, the raising machine has the ability to actively correct when the fabric raising thickness deviates. The overall structural principle is simple and the design is reasonable, which not only improves the raising quality and production efficiency of the fabric, but also significantly improves the fault tolerance of the equipment.

[0027] The torsion assembly 609 includes a bracket 6091, a push block 6094 and a telescopic rod 6095. The bracket 6091 is fixedly mounted at both ends of the inner part of the outer cover 603. A torsion ring 6092 is rotatably connected between the bracket 6091 and the outer cover 603. The torsion ring 6092 and the outer cover 603 are both provided with a needle hole 6093 for passing the pile needle 606. The push block 6094 is provided on the outer wall of the two ends of the torsion ring 6092. The telescopic rod 6095 is mounted on the inner wall of the outer cover 603. The output end of the telescopic rod 6095 is connected to the push block 6094. The telescopic rod 6095 can be a hand-operated telescopic rod 6095, which is convenient for the staff to manually adjust it on the outer side of the outer cover 603, or it can be an electric telescopic rod 6095 controlled and adjusted by a remote controller or a controller 8.

[0028] In actual pile finishing, the straight needles rotate against the moving direction of the fabric to perform pile drawing, and the oblique needles move along the pile drawing direction to perform brushing. Since the pile needles 606 are made of steel wire material, which is soft and elastic, some of the straight pile needles 606 can be twisted into oblique needles as needed before the pile drawing work. In this way, the final quality of the pile drawing can be significantly improved by brushing while pile drawing. During operation, the telescopic rod 6095 in the selected needle roller is started. The telescopic rod 6095 drives the torsion ring 6092 to rotate clockwise or counterclockwise for a certain distance by pushing or pulling back the push block 6094 as needed, so that the torsion ring 6092 is misaligned with the needle hole 6093 on the outer cover 603, thereby causing the pile needles 606 to be twisted from straight needles to oblique needles, completing the conversion of the working state.

[0029] By twisting the component 609, the shape transformation of the pile needles 606 on the pile roller group 6 is achieved. The staff can independently select the number and distribution of straight needle rollers and oblique needle rollers according to needs. The operation is simple and fast, which further improves the final quality of the fabric and enriches the practicality of the pile raising machine and its flexibility in the application process.

[0030] The lifting assembly 702 includes a screw rod 7021. The screw rod 7021 is vertically rotated and connected in the installation cavity on both sides of the shell 1. The screw rod 7021 is threadedly connected with a lifting nut 7022. The lifting platform 703 passes through the notch on the shell 1 and is connected to the lifting nut 7022. The upper end of the screw rod 7021 passes through the installation cavity at the upper end of the shell 1. The upper end of the screw rod 7021 is provided with a hexagonal groove 7023. When the height of the lifting platform 703 needs to be adjusted, the screw rod 7021 is rotated, and the screw rod 7021 can adjust the height of the lifting platform 703 by lifting and lowering the lifting nut 7022. The screw rod 7021 can be driven by a motor or driven to rotate through the hexagonal groove 7023 at the top.

[0031] The conductive assembly 710 includes a first conductive slip ring 7101 and a second conductive slip ring 7102. The first conductive slip ring 7101 is installed at one end of the drive shaft 3, and one end interface of the first conductive slip ring 7101 is connected to the first conductive strip 708 through a wire. The second conductive slip ring 7102 is installed in a mounting hole on the mounting plate 5, and the two end interfaces of the second conductive slip ring 7102 are respectively connected to the electromagnetic ring 607 and the first conductive slip ring 7101 through wires. The electromagnetic ring 607 and the drive shaft 3 are both in a rotating state during operation, and the first conductive slip ring 7101 and the second conductive slip ring 7102 can ensure that the circuit between the electromagnetic ring 607 and the controller 8 is connected in the rotating state.

[0032] A plurality of rollers for reducing friction are symmetrically rotatably connected on the end surfaces of the adjacent sides of the upper pressing plate 701 and the lower pressing plate 705 .

[0033] The needle hole 6093 is a through-going conical hole, which can provide the pile needle 606 with sufficient twisting space and also reduce the contact surface, thereby reducing the force required for the pile needle 606 to twist.

[0034] The inner side of the outer cover 603 is slidably connected to the end of the push block 6094 by providing a sliding groove to improve the stability of the torsion ring 6092.

[0035] Working principle: When the napping machine needs to perform napping finishing, the screw rod 7021 is first rotated to set the initial height of the lifting platform 703 according to the standard thickness of the fabric after napping. Then the controller 8 sets the current required by the electromagnetic ring 607 according to the required napping thickness of the fabric, so that the electromagnetic ring 607 is supplied with a constant current. After the electromagnetic ring 607 is energized, a certain repulsive force is generated on the lifting magnetic plate 605. The magnitude of the repulsive force is determined by the magnitude of the current. The constant repulsive force enables the lifting magnetic plate 605 to overcome the elastic force of the return spring 608 and drive the napping needle 606 to extend a certain distance to the outside of the outer cover 603. Then, according to the need for brushing, the telescopic rod 6095 in a part of the selected needle roller is started. The telescopic rod 6095 drives the torsion ring 6092 to rotate clockwise or counterclockwise for a certain distance by pushing or pulling back the push block 6094 according to the need, so that the torsion ring 6092 is misaligned with the pinhole 6093 on the outer cover 603, so that the napping needle 606 is twisted from a straight needle to an oblique needle, and has the ability to brush. At this time, the drive shaft 3 and the power part 602 can be started to perform the raising operation. If the thickness of the fabric after raising is the standard value, the horizontal telescopic connecting rod 706 will remain horizontal throughout the process to achieve balance. If the thickness of the fabric changes during the raising process, the lower pressure plate 705 will correspondingly overcome the resistance of the telescopic support 704 to rise or fall, and the up and down displacement of the lower pressure plate 705 is transmitted to the horizontal telescopic connecting rod 706 through the vertical telescopic connecting rod 707, thereby driving the second conductive strip 709 and the first conductive strip 708 to slide relative to each other. If the fabric thickness is too thick, the second conductive strip 709 slides upward relative to the first conductive strip 708. At this time, the current on the electromagnetic ring 607 decreases, and the repulsive force on the lifting magnetic plate 605 is also reduced. The raising needle 606 will be correspondingly recovered into the outer cover 603, so that the thickness of the raising is reduced until the standard thickness is restored. If the fabric is too thin, the second conductive strip 709 will slide downward relative to the first conductive strip 708. At this time, the current on the electromagnetic ring 607 will increase, and the repulsive force on the lifting magnetic plate 605 will also increase.
