Description
Technical Field
[0001] The utility model belongs to the technical field of knitted single jersey production, in particular to a pretreatment device for reducing the tension of knitted single jersey for preventing shrinkage. Background Art
[0002] Sweat cloth refers to the weft knitted fabric used to make underwear. It has a smooth surface, clear lines, fine texture, and smooth feel. It has good longitudinal and transverse extensibility, and the transverse extensibility is greater than the longitudinal extensibility. It has good moisture absorption and breathability. It is used to make various styles of sweat shirts and vests. The fabric usually shrinks after washing, so it needs to be pre-shrunk before using it. However, it still has the following disadvantages in actual use:
[0003] During the pretreatment of knitted jersey, steam is directly sprayed onto the jersey to pre-shrink the jersey. However, during the treatment, the steam contacts the jersey for a short time, which causes the steam on the jersey to evaporate quickly, and the shrinkage treatment is not sufficient.
[0004] After pretreatment of the knitted jersey, wrinkles will appear on the jersey due to uneven shrinkage during the subsequent processing, resulting in poor aesthetics of the jersey and affecting the quality of the finished jersey product. Therefore, it needs to be flattened. During the flattening process, different knitted jerseys require different roller pressures, and it is inconvenient to adjust and control the roller pressure. Utility Model Content
[0005] The utility model aims to provide a pretreatment device for reducing the tension of knitted single jersey for shrinkage prevention. By arranging a steam chamber, a conveying shell, a workbench and a pressing plate, the utility model solves the problems that the contact time between the steam and the single jersey for pretreatment of knitted single jersey is not long enough and the flattening force after shrinkage is inconvenient to adjust.
[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

When working, the steam chamber is used to accommodate the steam for pre-shrinking the knitted single fabric, the conveying shell is used for conveying high-pressure steam, and the workbench is used for conveying the knitted single fabric after shrinkage treatment in the steam chamber, and the pressure transmitted to the pressing roller by the compression spring is changed by pressing down the pressing plate.
[0008] Furthermore, a row of rotating shafts are rotatably connected above the transverse center lines on both sides of the inner wall of the steam chamber, and rotating shafts are movably connected below the rotating shafts on both sides of the steam chamber. The rotating shafts above and below the transverse center lines on both sides of the inner wall of the steam chamber correspond to each other one by one, and inner rotating rollers are fixed to the ends of the rotating shafts in the steam chamber, and the corresponding circumferences of the inner rotating rollers are fitted together above and below, and the steam chamber is connected to the inner rotating rollers through the rotating shafts.
[0009] Furthermore, outer rotating rollers are fixed to the ends of the rotating shafts that are away from each other below the horizontal center lines on both sides of the steam chamber, and the outer rotating rollers adjacent to each other on the same side of the steam chamber are all connected to the transmission belts by rotating together. The steam chamber is connected to the transmission belts through the outer rotating rollers, and when one outer rotating roller rotates, all the outer rotating rollers are driven to rotate.
[0010] Furthermore, all the outer rotating rollers on the same side of the steam chamber are rotatably connected to a limiting plate at one end away from the steam chamber, a driving motor is fixed to the side of the limiting plate away from the outer rotating roller, the output shaft of the driving motor is movably connected through the limiting plate and fixed to an outer rotating roller, and the steam chamber limits the position of the transmission belt on the outer rotating roller through the limiting plate.
[0011] Furthermore, a plurality of equally spaced spray pipes are fixed on one side of the conveying shell close to the steam chamber, and the spray pipes are passed through the lower inner part of a fixed cover plate fixed in the steam chamber close to one end of the conveying shell.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1
[0025] See also Figure 1-5 The utility model is a pretreatment device for reducing the tension of knitted single jersey for shrinkage prevention, comprising a steam chamber 1, a conveying shell 2, a workbench 3 and a pressing plate 4. Fixed cover plates 101 are fixed at both ends of the steam chamber 1. The steam chamber 1 is closed by the fixed cover plates 101 and provides a space for accommodating high-pressure steam. An inlet and outlet 102 is opened horizontally through the middle of the fixed cover plates 101. The knitted single jersey enters and exits the fixed cover plates 101 through the inlet and outlet 102. A conveying shell 2 is arranged on the outside of the fixed cover plate 101 at one end of the steam chamber 1. The conveying shell 2 transfers the high-pressure steam and conveys the high-pressure steam to the spray pipe 201. The steam chamber 1 is far away A workbench 3 is arranged on the outside of the fixed cover plate 101 at one end of the conveying shell 2. The top of the workbench 3 is flush with the bottom of the inlet and outlet 102. The knitted sweat cloth treated with steam is conveyed through the workbench 3. A pressing plate 4 is symmetrically arranged along the horizontal center line above the workbench 3. Compression springs 402 are fixed at the two short sides of the bottom of the pressing plate 4. A connecting plate 403 is commonly fixed at the bottom ends of the two compression springs 402 at the bottom of the same pressing plate 4. When the pressing plate 4 is lifted or lowered, the compression springs 402 are compressed differently. The compression of the compression springs 402 drives the connecting plate 403 to be pressed down, so that the connecting plate 403 drives the pressing roller 405 to be pressed down.
[0026] Specifically, a row of rotating shafts 103 are rotatably connected above the horizontal center lines on both sides of the inner wall of the steam chamber 1, and rotating shafts 103 are movably connected below the rotating shafts 103 on both sides of the steam chamber 1. The rotating shafts 103 above and below the horizontal center lines on both sides of the inner wall of the steam chamber 1 correspond to each other one by one. Inner rotating rollers 104 are fixed to the ends of the rotating shafts 103 in the steam chamber 1, and the circumferences of the upper and lower corresponding inner rotating rollers 104 fit each other. The steam chamber 1 is connected to the inner rotating rollers 104 through the rotating shafts 103, and the position of the knitted sweat cloth is limited by the upper and lower corresponding inner rotating rollers 104.
[0027] Furthermore, outer rollers 105 are fixed to the ends of the lower rotating shafts 103 on both sides of the transverse center lines in the steam chamber 1 that are away from each other, and the outer rollers 105 adjacent to each other on the same side of the steam chamber 1 are circumferentially connected to a transmission belt 106 that rotates together. The steam chamber 1 transmits power through the transmission belt 106 connected to the outer roller 105. When the outer roller 105 rotates, the transmission belt 106 connected to the outer roller 105 is driven to rotate, thereby assisting the movement of the knitted sweat fabric in the steam chamber 1.
[0028] Furthermore, all the outer rotating rollers 105 on the same side of the steam chamber 1 are rotatably connected to the limiting plate 107 at one end away from the steam chamber 1, and a driving motor 108 is fixed to the side of the limiting plate 107 away from the outer rotating roller 105. The output shaft of the driving motor 108 is movably connected in the limiting plate 107 and is fixed to an outer rotating roller 105. The steam chamber 1 limits the position of the transmission belt 106 on the outer rotating roller 105 through the limiting plate 107, and drives the outer rotating roller 105 to rotate through the driving motor 108.
[0029] Furthermore, a plurality of equally spaced spray pipes 201 are fixed to one side of the conveying shell 2 close to the steam chamber 1. The spray pipes 201 pass through the lower inner portion of a fixed cover plate 101 fixed to one end of the steam chamber 1 close to the conveying shell 2. An input pipe 202 is fixedly connected to one end of the conveying shell 2. The end of the input pipe 202 away from the conveying shell 2 is connected to a pipeline for conveying high-pressure steam. The conveying shell 2 conveys steam therein through the input pipe 202, which is then transferred to the spray pipe 201, and then conveyed to the steam chamber 1 through the spray pipe 201, contacting the knitted sweat cloth in the steam chamber 1, so that the knitted sweat cloth shrinks in advance.
[0030] The operation process of this embodiment is as follows: when working, the conveying shell 2 conveys steam therein through the input pipe 202, and then transfers it to the spray pipe 201, and then conveys it to the steam chamber 1 through the spray pipe 201. At the same time, the knitted sweat cloth enters the steam chamber 1 through the inlet and outlet 102 in the fixed cover plate 101 close to the conveying shell 2. After being supported by the upper and lower corresponding inner rollers 104 in the steam chamber 1, the driving motor 108 is started to drive the outer rollers 105 to rotate. Through the cooperation of the transmission belt 106, all the outer rollers 105 rotate together, driving the rotating shaft 103 to rotate, driving the inner rollers 104 to rotate, and conveying the knitted sweat cloth. When the knitted sweat cloth passes through the steam chamber 1, the steam rises and blows onto the knitted sweat cloth, and is output through the inlet and outlet 102. The contact time of the steam is longer and the knitted sweat cloth shrinks more fully. Specific embodiment 2
[0031] See also Figure 1 , 4 5. On the basis of the specific embodiment 1, the top of the connecting plate 403 in the compression spring 402 is fixed with a telescopic rod 401, and the telescopic end of the telescopic rod 401 is fixed to the bottom of the pressing plate 4. The bottoms of the two connecting plates 403 are fixed with fixed blocks 404 at equal intervals. The fixed blocks 404 corresponding to each other at the bottoms of the two connecting plates 403 are connected with pressure rollers 405 for common rotation. All pressure rollers 405 are arranged on the top of the workbench 3. Two electric push rods 406 are fixed to the bottom of the pressing plate 4 outside each connecting plate 403. When working, the pressing plate 4 is driven to rise and fall by the electric push rods 406. The lifting of the pressing plate 4 drives the compression spring 402 to change the compression force, so that the pressure applied to the connecting plate 403 by the pressure roller 405 changes, and the pressure applied to the pressure roller 405 by the fixed block 404 changes. After being pressed onto the workbench 3 by the pressure roller 405, it is pressed onto the knitted sweat cloth passing on the workbench 3.
[0032] The operation process of this embodiment is as follows: when working, the knitted sweat cloth is transported to the inlet and outlet 102 in the fixed cover plate 101 through the production equipment of the sweat cloth, and then enters the steam chamber 1 through the inlet and outlet 102 for steam shrinkage, and is output through the inlet and outlet 102 on another fixed cover plate 101. After output, it is transported to the pressing plate 4, and after passing through the pressing plate 4, it is transported to the equipment for the next processing. The equipment for the next processing pulls the knitted sweat cloth so that the knitted sweat cloth passes through the workbench 3. When the knitted sweat cloth passes through the workbench 3, the pressing plate 4 is driven to rise and fall by the electric push rod 406. The lifting of the pressing plate 4 drives the compression spring 402 to change the compression elastic force, so that the pressure applied to the connecting plate 403 changes, and the pressure applied to the pressing roller 405 by the fixed block 404 is changed. After being pressed onto the workbench 3 by the pressing roller 405, it is pressed onto the knitted sweat cloth passing on the workbench 3.
