[0002] Knitted fabric is a kind of fabric made of coils interlaced and connected. It is a large variety of fabrics. Knitted fabric has good elasticity, moisture absorption and breathability, comfort and warmth. It is the most widely used fabric for children's clothing. The raw materials are mainly natural fibers such as cotton, linen, silk and wool, as well as chemical fibers such as nylon, acrylic, polyester, etc. Knitted fabrics have rich changes in structure, a wide variety of varieties, and unique appearance. In the past, they were mostly used for underwear, T-shirts, etc.

[0003] Knitted fabrics often wrinkle during use, which seriously affects the processing of the knitted fabrics and causes deviations in the knitted fabrics during clothing production. Therefore, people need to iron the knitted fabrics using an ironing device.

[0004] However, in the process of using the existing ironing device, the contact area with the fabric during ironing is too small, and the fabric is always in a moving state, which results in the wrinkles on the fabric being conveyed away before being ironed after coming into contact with the iron, resulting in the wrinkles not being completely ironed. The only way to deal with it is to slow down the conveying speed of the fabric, and the reduction in conveying speed will lead to a reduction in the pressing efficiency of the fabric, thereby reducing production efficiency.

DETAILED DESCRIPTION

[0022] 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 in 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.

[0023] like Figure 1-Figure 4 As shown, a pressing device for knitted fabrics comprises a processing frame 1, a feeding roller 2, a receiving roller 3 and an ironing machine 6. Two groups of rotating shafts 4 in a rectangular array are rotatably connected inside the processing frame 1. The outer walls of the two groups of rotating shafts 4 are rotatably connected with smoothing belts 5. The adjacent belt surfaces of the two groups of smoothing belts 5 are arranged in parallel. There are two groups of ironing machines 6. The working surfaces of the two groups of ironing machines 6 are respectively in contact with the adjacent belt surfaces of the two groups of smoothing belts 5. The side walls of the two groups of ironing machines 6 are fixedly connected with adjustment blocks 7 for adjusting positions. The side walls of the processing frame 1 are rotatably connected with a bidirectional screw rod 701. The two groups of adjustment blocks 7 are threadedly connected to the outer wall of the bidirectional screw rod 701. One end of the bidirectional screw rod 701 is connected to a driving motor 702 arranged on the side wall of the processing frame 1.

[0024] like Figure 1As shown, a further solution is that the side walls of the two groups of adjusting blocks 7 mentioned above are fixedly connected with adjusting plates 8, and two groups of sliding rods 801 are slidably connected to the adjusting plates 8. The ends of the sliding rods 801 are fixedly connected to the ironing machine 6, and the outer walls of the sliding rods 801 are sleeved with springs 802. The two ends of the springs 802 are respectively against the adjusting plates 8 and the ironing machine 6. When the adjusting blocks 7 push the ironing machine 6 to move, the adjusting blocks 7 drive the adjusting plates 8 to slide on the two groups of sliding rods 801, and then squeeze the springs 802. By squeezing the springs 802, the ironing machine 6 is driven to move to apply pressure to the fabrics between the two groups of smoothing belts 5, thereby avoiding excessive squeezing of the fabrics to cause damage to the fabrics, thereby improving the safety of pressing.

[0025] like Figure 3 and Figure 4 As shown, two groups of relatively arranged air-drying racks 9 are fixedly connected to the inner wall of the processing rack 1, a cavity 901 is opened inside the air-drying rack 9, a through slot 902 penetrating the air-drying rack 9 is opened on one side of the cavity 901, and the through slots 902 on the two groups of air-drying racks 9 are staggered, and an air supply fan 905 connected to the cavity 901 is fixedly connected to the inner wall of the processing rack 1. By starting the air supply fan 905, air is drawn into the cavity 901 inside the two groups of air-drying racks 9, and then blown to the upper and lower sides of the fabric through multiple groups of through slots 902, thereby cooling the upper and lower sides of the fabric and removing moisture to avoid moisture remaining in the fabric.

[0026] like Figure 3 and Figure 4 As shown, a plurality of exhaust slots 903 are provided on opposite sides of the two groups of air-drying racks 9. The exhaust slots 903 on one group of air-drying racks 9 are aligned with the through slots 902 on the other group of air-drying racks 9. The exhaust slots 903 penetrate the air-drying racks 9 through the connecting slots 904. The hot air and moisture blown out from the fabrics through the two groups of through slots 902 are discharged through the two groups of exhaust slots 903 arranged on the two groups of air-drying racks 9, so as to avoid the hot air from remaining in the two groups of air-drying racks 9.

[0027] like Figure 1 As shown, two groups of heating covers 10 arranged opposite to each other are fixedly connected to the inner wall of the processing frame 1 mentioned above, and the fabric passes through between the two groups of heating covers 10. The heating covers 10 are connected to the connecting groove 904 on the side wall of the air-drying frame 9 through the connecting pipe 906. The moisture and heat blown out from the fabric by the through groove 902 in the exhaust groove 903 enter the interior of the heating cover 10 through the connecting pipe 906, and then are blown to the fabric through the heating cover 10, so as to preheat and humidify the fabric entering the front position of the smoothing belt 5, thereby improving the effect of subsequent ironing and smoothing.

[0028] The working principle of the utility model is as follows: when the user uses it, the fabric is sleeved onto the outer wall of the feed roller 2, and then one end of the fabric is passed between the two groups of smoothing belts 5, and then passed between the two groups of air-drying racks 9 and then wound onto the outer wall of the receiving roller 3. Then, according to the thickness and material of the fabric, the drive motor 702 is started, and the drive motor 702 drives the bidirectional screw rod 701 to rotate. The two groups of thread grooves on the outer wall of the bidirectional screw rod 701 with opposite rotation directions drive the two groups of adjusting blocks 7 to rotate in the grooves on the processing rack 1 ( Figure 1 and Figure 2 5, and the two sets of adjusting blocks 7 drive the two sets of ironing machines 6 to move, and the pressure of the fabric between the two sets of smoothing belts 5 applied by the two sets of ironing machines 6 can be synchronously adjusted, so as to facilitate the pressing of fabrics of different thicknesses, and at the same time, the pressing force on the fabric can be adjusted to improve the quality of pressing. Then, the fabric can be rolled up by starting the receiving roller 3 to rotate, and the two sets of ironing machines 6 and the two sets of rotating shafts 4 are started to rotate. After the ironing machine 6 is started, heated steam is sprayed out while heating. The temperature and steam generated by the heating pass through the smoothing belt 5 and are transferred to the fabric, and the fabric is heated and steam softened. At the same time, the two sets of rotating shafts 4 drive the two sets of smoothing belts 5 to rotate, and the rotation direction of the two sets of smoothing belts 5 is opposite to the movement direction of the fabric. Through the movement of the belt surface of the smoothing belt 5 and the pressure applied to the fabric by the ironing machine 6 through the smoothing belt 5, the fabric softened by the ironing machine 6 is pressed, and the stability and effect of pressing are improved.

[0029] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
