Description

Technical Field

[0001] This application relates to the dyeing and bleaching of knitted fabrics, and more particularly to a rapid dyeing and bleaching apparatus for knitted fabrics that is energy-saving and environmentally friendly. Background Technology

[0002] Knitted fabrics refer to blended fabrics of polyester and cotton. Polyester-cotton knitted fabrics highlight the style of polyester while having the advantages of cotton fabrics. They have good elasticity and abrasion resistance in both dry and wet conditions, and are very popular among consumers.

[0003] A current patent (publication number: CN222251344U) discloses a one-bath dyeing and bleaching equipment for knitted fabrics, including a box body, connecting plates fixed to one side of the box body for feeding; a container placed between two sets of connecting plates; an inlet / outlet on one side of the container; a recycling bin installed inside the container via the inlet / outlet; a lower collection port installed at the bottom of the container; an upper collection port symmetrically installed above the lower collection port; connecting accessories installed between the container and the recycling bin and the lower collection port; and fans installed in two spaces divided by the container. This invention sets a lower and upper collection port in the feeding direction of the box body. The knitted fabric passes through the lower and upper collection ports, and the surface of the knitted fabric is pre-treated by the container located below the lower collection port and the fans inside the container, reducing the possibility of impurities on the surface of the knitted fabric entering the dye bath with the fabric, thus improving the quality of the knitted fabric dyeing and bleaching process.

[0004] While the device described in the aforementioned comparative document solves the problem that the lack of pre-treatment of knitted fabrics for dust and lint removal before dyeing and bleaching affects the quality of the fabrics, it lacks a limiting mechanism and adjustment function during the mechanical transport of the fabric. When the fabric becomes loose or shifts during transport, it can easily lead to wrinkles or even damage, which can affect the smooth progress of subsequent dyeing and bleaching processes. To address these issues, a rapid dyeing and bleaching device for knitted fabrics that is energy-saving and environmentally friendly is proposed. Utility Model Content

[0005] The purpose of this application is to provide a rapid dyeing and bleaching device for energy-saving and environmentally friendly knitted fabrics, which has the advantages of convenient limiting mechanism and adjustment function. It solves the problem that the fabric is prone to loosening or shifting during transportation, which can easily lead to fabric wrinkles or even damage, and affect the smooth progress of subsequent dyeing and bleaching processes.

[0006] The present application provides a rapid dyeing and bleaching device for knitted fabrics for energy conservation and environmental protection, which adopts the following technical solution: it includes a box and a dust collection box, and the top of the box is sequentially fixedly connected with a first U-shaped frame, a second U-shaped frame, a third U-shaped frame and a fourth U-shaped frame;

[0007] The housing is internally connected by pins to two upper limit rollers and four lower limit rollers. The upper limit rollers are located on top of the lower limit rollers. Two movable plates are slidably connected inside the first and third U-shaped frames. A connecting rod is fixedly connected to the bottom of each movable plate. Limit rings are fixedly connected to opposite sides of the bottom of each connecting rod, and the limit rings are slidably connected to the surface of the upper limit rollers. An electric push rod is fixedly connected inside the second U-shaped frame. A first U-shaped plate is fixedly connected to the bottom of the electric push rod. Movable grooves are formed on opposite sides inside the first U-shaped plate. A pressure sensor is fixedly connected to the bottom of each movable groove. A movable block is fixedly connected to the top of each pressure sensor. An adjusting roller is tightly nested between the two movable blocks via bearings. A limit frame is fixedly connected to the middle of the bottom of the connecting rod, and the limit frame is slidably connected to the surface of the adjusting roller. A dual-axis motor is fixedly connected inside the first U-shaped frame. A threaded rod is fixedly connected to the output end of the dual-axis motor. The shaft end of the threaded rod is rotatably connected to the inner side of the first U-shaped frame. A threaded cylinder is threadedly connected to the surface of the threaded rod. A movable plate slidably connected inside the first U-shaped frame is fixedly connected to the surface of the threaded cylinder.

[0008] By adopting the above technical solution, and through the coordinated arrangement of structures such as the upper limit roller, lower limit roller, movable plate, limit ring, electric push rod, adjusting roller, and pressure sensor, the functions of limiting and adjusting tension during the transportation of knitted fabrics can be realized. When the knitted fabric is transported in the box, the upper limit roller and the lower limit roller form an upper and lower clamping limiting structure, which can prevent the knitted fabric from shifting in the horizontal direction. At the same time, the dual-axis motor drives the threaded rod to rotate, which drives the threaded cylinder and movable plate to move, so that the limit ring at the bottom of the connecting rod slides along the surface of the upper limit roller, thereby adjusting the distance between the two limit rings according to the width of the knitted fabric, which can further improve the lateral limiting effect. When adjusting tension, the electric push rod pushes the first U-shaped plate down, so that the adjusting roller contacts the knitted fabric. When the knitted fabric becomes loose or tight during transportation, it will generate different pressures on the adjusting roller. The pressure is transmitted to the pressure sensor through the movable block. The pressure sensor feeds the signal back to the control system. The control system controls the extension and retraction of the electric push rod according to the preset pressure threshold, adjusts the height of the adjusting roller, and thus adjusts the tension of the knitted fabric, avoiding fabric wrinkles or damage due to improper tension.

[0009] Preferably, a sliding rod is fixedly connected inside the third U-shaped frame, and two sliding cylinders are slidably connected to the surface of the sliding rod. A movable plate slidably connected inside the third U-shaped frame is fixedly connected to the surface of the sliding cylinders.

[0010] By adopting the above technical solution and setting the sliding cooperation between the slide rod and the slide cylinder, a stable guide can be provided for the movement of the movable plate, which can prevent the movable plate from deviating or getting stuck during the movement.

[0011] Preferably, two telescopic rods are fixedly connected inside the second U-shaped frame, the electric push rod is located between the two telescopic rods, and the bottom end of the telescopic rod is fixedly connected to the top of the second U-shaped plate;

[0012] By adopting the above technical solution, and by setting two telescopic rods on both sides of the electric push rod, it can provide auxiliary support and guidance when the electric push rod pushes the second U-shaped plate to move up and down. When the electric push rod extends and retracts to drive the second U-shaped plate to move, the telescopic rods extend and retract synchronously, effectively preventing the second U-shaped plate from tilting or swaying during the movement.

[0013] Preferably, the box body is provided with an agitation structure, which includes three agitation rollers, and the three agitation rollers are interconnected by gears and gear chains;

[0014] By adopting the above technical solution and setting up three mutually driving agitating rollers, the knitted fabric and dyeing solution can be fully agitated inside the box, thereby improving the dyeing efficiency and effect, reducing the dyeing time and the amount of chemical agents used, and achieving the goal of energy saving and environmental protection.

[0015] Preferably, the dust collector has an inlet and an outlet on opposite sides inside, with the inlet at the top of the outlet. Both the inlet and outlet are connected to guide rollers via pins. Two dust collection buckets are fixedly connected between the upper and lower guide rollers. A vibration structure is provided on the inner side of the dust collector.

[0016] By adopting the above technical solution and setting up a vibration structure, the transported fabric can be vibrated, which can remove dust and lint adhering to the fabric surface. Then, the removed impurities can be sucked in and collected in time through a dust collection bucket, effectively preventing impurities from entering the subsequent dyeing and bleaching process and affecting the dyeing and bleaching quality, thus improving the cleanliness of the pre-dyeing and bleaching treatment of knitted fabrics.

[0017] Preferably, a U-shaped tube is fixedly connected between the output ends of the two dust collection buckets, a dust collection box and a vacuum cleaner are fixedly connected to the bottom of the dust collection box, a suction pipe is fixedly connected to the input end of the vacuum cleaner, the input end of the suction pipe is fixedly connected to the surface of the U-shaped tube, the output end of the vacuum cleaner is located on the inner side of the dust collection box, and a collector is fixedly connected to the bottom of the dust collection box;

[0018] By adopting the above technical solution and setting up a U-shaped tube, the dust and lint adsorbed by the two dust collection buckets can be collected and transported to the vacuum cleaner through the dust collection tube. The negative pressure generated by the vacuum cleaner sucks in the impurities and discharges them into the dust collection box through the output end for preliminary collection. Finally, the impurities fall into the collector at the bottom, which can realize the centralized treatment of impurities on the surface of knitted fabrics, which is convenient for subsequent cleaning and recycling.

[0019] Preferably, a diversion frame is fixedly connected to the side of the box, the fourth U-shaped frame is located at the top of the diversion frame, a fixed roller is movably connected inside the diversion frame via a pin, an elastic shrinking rod is fixedly connected to the top of the fourth U-shaped frame, a second U-shaped plate is fixedly connected to the bottom of the elastic shrinking rod, and a squeezing roller is movably connected inside the second U-shaped plate via a pin.

[0020] By adopting the above technical solution, by setting the guide frame and the fixed roller, the knitted fabric after passing through the fourth U-shaped frame can be guided and supported, avoiding the knitted fabric from shifting or wrinkling during the conveying process. Then, by the cooperation of the squeeze roller and the fixed roller, the excess dye liquor remaining on the surface of the knitted fabric after bleaching and dyeing can be effectively removed, which can reduce dye liquor waste.

[0021] Preferably, an adjusting bolt is threaded to the top of the inside of the fourth U-shaped frame, and a top plate is fixedly connected to the bottom of the adjusting bolt. The bottom of the top plate overlaps the top of the fourth U-shaped frame.

[0022] By adopting the above technical solution, and by setting an adjusting bolt and a top plate, people can rotate the adjusting bolt to push the top plate down, which can apply downward pressure to the second U-shaped plate, enhance the squeezing force of the squeezing roller on the knitted fabric, and ensure that knitted fabrics of different thicknesses can be subjected to stable and effective squeezing during transportation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This energy-saving and environmentally friendly rapid dyeing and bleaching device for knitted fabrics utilizes the coordinated structure of an upper limit roller, a lower limit roller, a movable plate, a limit ring, an electric push rod, an adjusting roller, and a pressure sensor to achieve limiting and tension adjustment functions during the transport of knitted fabrics. When the knitted fabric is transported within the box, the upper and lower limit rollers form a clamping structure to prevent horizontal displacement. Simultaneously, a dual-axis motor drives a threaded rod to rotate, moving a threaded cylinder and a movable plate, causing the limit ring at the bottom of the connecting rod to slide along the surface of the upper limit roller, thereby adjusting the tension according to the pressure sensor. Adjusting the distance between the two limiting rings to improve the lateral limiting effect can further enhance the width of the knitted fabric. When adjusting the tension, the electric push rod pushes the first U-shaped plate down, causing the adjusting roller to contact the knitted fabric. When the knitted fabric becomes loose or tight during transportation, it will generate different pressures on the adjusting roller. The pressure is transmitted to the pressure sensor through the movable block. The pressure sensor feeds the signal back to the control system. The control system controls the extension and retraction of the electric push rod according to the preset pressure threshold, adjusts the height of the adjusting roller, and thus adjusts the tension of the knitted fabric to avoid fabric wrinkles or damage due to improper tension.

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.

[0034] Example 1: A rapid dyeing and bleaching device for energy-saving and environmentally friendly knitted fabrics, referring to... Figure 1 , Figure 3 , Figure 4 and Figure 6 It includes a housing 1 and a dust collection box 2. The top of the housing 1 is sequentially fixedly connected with a first U-shaped frame 101, a second U-shaped frame 102, a third U-shaped frame 103 and a fourth U-shaped frame 104.

[0035] Inside the housing 1, two upper limit rollers 106 and four lower limit rollers 107 are movably connected by pins. The upper limit rollers 106 are located on top of the lower limit rollers 107. Two movable plates 1013 are slidably connected inside the first U-shaped frame 101 and the third U-shaped frame 103. Connecting rods 1014 are fixedly connected to the bottom of the two movable plates 1013. Limiting rings 1015 are fixedly connected to opposite sides of the bottom of the connecting rods 1014. The limiting rings 1015 are slidably connected to the surface of the upper limit rollers 106. An electric push rod 1017 is fixedly connected inside the second U-shaped frame 102. A first U-shaped plate 1019 is fixedly connected to the bottom end of the electric push rod 1017. Movable grooves 1020 are formed on opposite sides inside the first U-shaped plate 1019. A pressure sensor 1021 is fixedly connected to the bottom of the movable groove 1020. A movable block 1022 is fixedly connected to the top of the pressure sensor 1021. An adjusting roller 1023 is tightly nested between the two movable blocks 1022 via bearings. A limit frame 1016 is fixedly connected to the middle of the bottom of the connecting rod 1014. The limit frame 1016 is slidably connected to the surface of the adjusting roller 1023. A dual-axis motor 108 is fixedly connected inside the first U-shaped frame 101. A threaded rod 109 is fixedly connected to the output end of the dual-axis motor 108. The shaft end of the threaded rod 109 is rotatably connected to the inner side of the first U-shaped frame 101. A threaded cylinder 1010 is threadedly connected to the surface of the threaded rod 109. A movable plate 1 is slidably connected inside the first U-shaped frame 101. 013 is fixedly connected to the surface of the threaded cylinder 1010. Through the cooperation of structures such as the upper limit roller 106, lower limit roller 107, movable plate 1013, limit ring 1015, electric push rod 1017, adjusting roller 1023, and pressure sensor 1021, the functions of limiting and adjusting tension during the transport of knitted fabrics can be realized. When the knitted fabric is transported inside the box 1, the upper limit roller 106 and lower limit roller 107 form an upper and lower clamping limiting structure, which can prevent the knitted fabric from shifting in the horizontal direction. At the same time, the dual-axis motor 108 drives the threaded rod 109 to rotate, causing the threaded cylinder 1010 and movable plate 1013 to move, so that the limit ring 1015 at the bottom of the connecting rod 1014 moves along the surface of the upper limit roller 106. The sliding surface allows for adjustment of the distance between the two limiting rings 1015 according to the width of the knitted fabric, further improving the lateral limiting effect. During tension adjustment, the electric push rod 1017 pushes the first U-shaped plate 1019 downward, causing the adjusting roller 1023 to contact the knitted fabric. When the knitted fabric becomes loose or tight during transport, it will generate different pressures on the adjusting roller 1023. The pressure is transmitted to the pressure sensor 1021 through the movable block 1022. The pressure sensor 1021 feeds the signal back to the control system. The control system controls the extension and retraction of the electric push rod 1017 according to the preset pressure threshold, adjusting the height of the adjusting roller 1023, thereby adjusting the tension of the knitted fabric and avoiding fabric wrinkles or damage due to improper tension.

[0036] Please see Figure 4and Figure 6 The third U-shaped frame 103 has a slide rod 1011 fixedly connected inside. Two slide cylinders 1012 are slidably connected to the surface of the slide rod 1011. A movable plate 1013, slidably connected inside the third U-shaped frame 103, is fixedly connected to the surface of the slide cylinders 1012. By setting the slide rod 1011 and slide cylinders 1012 in a sliding engagement, stable guidance can be provided for the movement of the movable plate 1013, preventing it from shifting or jamming during movement. The second U-shaped frame 102 has two telescopic rods 1018 fixedly connected inside, electrically propelled... Rod 1017 is located between two telescopic rods 1018. The bottom end of the telescopic rod 1018 is fixedly connected to the top of the second U-shaped plate 1026. By setting two telescopic rods 1018 on both sides of the electric push rod 1017, they can provide auxiliary support and guidance when the electric push rod 1017 pushes the second U-shaped plate 1026 to move up and down. When the electric push rod 1017 extends and retracts to drive the second U-shaped plate 1026 to move, the telescopic rod 1018 extends and retracts synchronously, effectively preventing the second U-shaped plate 1026 from tilting or swaying during movement.

[0037] Please see Figure 7 The box 1 is equipped with an agitation structure 3, which includes three agitation rollers. The three agitation rollers are interconnected by gears and gear chains. By setting up three interconnected agitation rollers, the knitted fabric and dyeing solution can be fully agitated inside the box 1, thereby improving the dyeing efficiency and effect, reducing the dyeing time and the amount of chemical agents used, and achieving the purpose of energy saving and environmental protection.

[0038] Please see Figure 3 and Figure 5The dust collector 2 has an inlet 201 and an outlet 202 on opposite sides inside. The inlet 201 is located at the top of the outlet 202. Both the inlet 201 and outlet 202 are movably connected to guide rollers 203 via pins. Two suction buckets 204 are fixedly connected between the upper and lower guide rollers 203. A vibration structure 4 is provided on the inner side of the dust collector 2. By setting the vibration structure 4, the transported fabric can be vibrated, which can remove dust and lint adhering to the fabric surface. Then, the suction buckets 204 can suck in and collect the removed impurities in time, effectively preventing impurities from entering the subsequent dyeing process and affecting the dyeing quality, thus improving the cleanliness of the pre-dyeing treatment of knitted fabrics. A U-shaped tube 20 is fixedly connected between the output ends of the two suction buckets 204. 5. A dust collection box 208 and a vacuum cleaner 206 are fixedly connected to the bottom of the dust collection box 2. A suction pipe 207 is fixedly connected to the input end of the vacuum cleaner 206. The input end of the suction pipe 207 is fixedly connected to the surface of the U-shaped tube 205. The output end of the vacuum cleaner 206 is located inside the side of the dust collection box 208. A collector 209 is fixedly connected to the bottom of the dust collection box 208. By setting the U-shaped tube 205, the dust and lint adsorbed by the two dust collection boxes 204 can be collected and transported to the vacuum cleaner 206 through the suction pipe 207. The negative pressure generated by the vacuum cleaner 206 sucks in the impurities and discharges them into the dust collection box 208 through the output end for preliminary collection. Finally, the impurities fall into the collector 209 at the bottom, which can realize the centralized treatment of impurities on the surface of knitted fabrics, which is convenient for subsequent cleaning and recycling.

[0039] Please see Figure 1 and Figure 2A guide frame 105 is fixedly connected to the side of the housing 1. A fourth U-shaped frame 104 is located at the top of the guide frame 105. A fixed roller 1024 is movably connected inside the guide frame 105 via a pin. An elastic shrinking rod 1025 is fixedly connected to the top of the fourth U-shaped frame 104. A second U-shaped plate 1026 is fixedly connected to the bottom of the elastic shrinking rod 1025. A squeezing roller 1027 is movably connected inside the second U-shaped plate 1026 via a pin. By setting the guide frame 105 and the fixed roller 1024, the knitted fabric after passing through the fourth U-shaped frame 104 can be guided and supported, preventing the knitted fabric from shifting or wrinkling during the conveying process. Then, the squeezing roller 1027 and the fixed roller 1024 are connected. The combined extrusion of roller 24 effectively removes excess dye residue from the surface of the knitted fabric after bleaching and dyeing, reducing dye waste. The top of the fourth U-shaped frame 104 is threaded with an adjusting bolt 1028, and the bottom of the adjusting bolt 1028 is fixedly connected to a top plate 1029. The bottom of the top plate 1029 overlaps the top of the fourth U-shaped frame 104. By setting the adjusting bolt 1028 and the top plate 1029, rotating the adjusting bolt 1028 can push the top plate 1029 down, which can apply downward pressure to the second U-shaped plate 1026, enhance the squeezing force of the extrusion roller 1027 on the knitted fabric, and ensure that knitted fabrics of different thicknesses can be subjected to stable and effective squeezing during transportation.

[0040] The implementation principle of this application embodiment is as follows: When in use, people put the fabric through the feed hole 201 of the dust collection box 2, and after being guided by the guide roller 203, it enters the dust collection box 2. Then, the vacuum cleaner 206 is started, and the dust collection bucket 204 is used to absorb the dust and lint on the surface of the knitted fabric. The impurities enter the dust collection box 208 through the U-shaped tube 205 and the suction pipe 207, and finally fall into the collector 209.

[0041] Next, the knitted fabric passes through the discharge hole 202 of the dust collector 2 and enters the interior of the housing 1. It passes through the lower limit roller 107 and the upper limit roller 106 in sequence, forming an S-shaped transport path. During this process, the dual-axis motor 108 drives the threaded rod 109 to rotate, which in turn moves the threaded cylinder 1010 and the movable plate 1013, causing the limiting ring 1015 to slide along the upper limit roller 106. The distance between the two limiting rings 1015 can be adjusted according to the width of the knitted fabric, thereby achieving lateral limiting. At the same time, the electric push rod 1017 pushes the first U-shaped plate 1019 downward, and the adjusting roller 1023 contacts the knitted fabric. When the tension of the knitted fabric changes, the movable block 1022 squeezes or disengages from the pressure sensor 1021. The pressure sensor 1021 feeds the signal back to the control system, and the control system controls the electric push rod 1017 to extend or retract to adjust the height of the adjusting roller 1023, thereby ensuring that the tension of the knitted fabric is appropriate.

[0042] The knitted fabric passes through the agitation structure 3 area, where three agitation rollers rotate synchronously under the transmission of gears and gear chains, fully agitating the knitted fabric and dyeing solution, thus completing the bleaching and dyeing reaction process of the fabric;

[0043] After the dyeing is completed, the knitted fabric is conveyed to the bottom of the fourth U-shaped frame 104. Rotating the adjusting bolt 1028 causes the top plate 1029 to move down, pushing the second U-shaped plate 1026 and the squeezing roller 1027 down. The squeezing roller 1027 cooperates with the fixed roller 1024 to squeeze the knitted fabric, which can remove excess dye liquor. Finally, the excess dye liquor can be guided into the box 1 through the drainage frame 105.
