Description

Technical Field

[0001] This utility model relates to the technical field of pre-wetting devices for textile printing and dyeing, specifically to a pre-wetting device for textile printing and dyeing. Background Technology

[0002] Before printing and dyeing, fabrics often have certain impurities on their surface. Furthermore, due to differences in the properties of various fabrics, dyes sometimes cannot fully adhere to the fabric during printing and dyeing. Therefore, pre-treatment of the fabric is necessary before printing and dyeing, and pre-wetting is one such pre-treatment process.

[0003] For example, the textile printing and dyeing pre-wetting device disclosed in patent CN222205730U can remove impurities from the fabric surface by brushing the fabric surface with a soft brush and rinsing with a spray head. However, in actual use, the use of a soft brush to brush the fabric surface makes it difficult to remove impurities attached to the fabric, resulting in limited impurity removal effect, and therefore needs to be improved.

[0031] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0032] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0033] like Figure 1 As shown, a textile printing and dyeing pre-wetting device in this embodiment includes a clean water tank 100, which stores clean water. The clean water tank 100 is equipped with a pressure roller 110 for pressing the fabric into the water. In actual use, an inlet roller 120 is provided at the upper end of the clean water tank 100. After the fabric is guided by the inlet roller 120, it passes through the pressure roller 110 and is then output from the clean water tank 100, thereby pre-soaking the fabric.

[0034] In this embodiment, the clean water tank 100 is provided with a swinging component 130 for swinging the fabric and a pushing component 140 for pushing the fabric at intervals. The pushing component 140 is located below the swinging component 130. The clean water tank 100 is provided with a squeezing component 150 for squeezing water from the output fabric. The swinging component 130 and the pushing component 140 are located in the clean water tank 100 between the inlet roller 120 and the pressure roller 110, so that the fabric input into the clean water tank 100 is swinging and being pushed at intervals to straighten it, thereby better removing impurities from the fabric. The squeezing component 150 is located at the end of the pressure roller 110, so as to squeeze water from the output fabric to control the moisture content of the fabric after pre-wetting treatment, which is convenient for subsequent printing and dyeing treatment of the fabric.

[0035] In practical use, the fabric is fed into the clean water tank 100 at intervals. The fabric between the inlet roller 120 and the pressure roller 110 is in a relaxed state, which allows the swing component 130 to swing the fabric between them in the clean water and the pushing component 140 to push the fabric downwards, so that the bent fabric is straightened, thereby better removing impurities from the fabric for subsequent dyeing and printing. After the pre-wetting treatment of this section of fabric is completed, the fabric in the clean water tank 100 is output, and a section of fabric to be processed is input, so that the fabric between the inlet roller 120 and the pressure roller 110 is in a relaxed state. By repeating the above operation, the dyeing and printing pre-wetting device can continuously process the fabric.

[0036] In this embodiment, the swing assembly 130 includes a swing frame 310, with a first rotating roller 311 for the fabric to pass through being disposed opposite to each other between the swing frames 310. The swing assembly 130 also includes a first driving member for driving the swing frame 310 to move horizontally back and forth. With the above structure, the swing assembly 130 can make the loose fabric between the guide roller 120 and the pressure roller 110 swing in clean water so that impurities on the fabric fall off.

[0037] The pushing assembly 140 includes a pushing frame 320, with a second rotating roller 321 for the fabric to pass through the pushing frames 320 opposite each other. The pushing assembly 140 also includes a second driving member for driving the pushing frames 320 to move vertically back and forth. With the above structure, the pushing assembly 140 can push the fabric down at intervals to straighten the fabric that is bent due to swinging, thereby promoting the effect of removing impurities from the fabric.

[0038] It should be noted that, in order to prevent fallen impurities from re-adhering to the output fabric, in this embodiment, a water spray pipe is arranged above the water surface in the clean water tank 100. Spray nozzles are linearly arranged on the water spray pipe. The spray nozzles spray the two sides of the output fabric to prevent impurities from re-adhering to the fabric and affecting the subsequent printing and dyeing of the fabric.

[0039] In this embodiment, an upper mounting plate 410 is provided inside the clean water tank 100. A horizontal sliding groove 411 is provided on the upper mounting plate 410 along the horizontal direction. A horizontal slider 312 is provided on the side wall of the swing frame 310 and slides in the corresponding horizontal sliding groove 411. The horizontal slider 312 slides in the horizontal sliding groove 411 so that the swing frame 310 is horizontally slidably installed inside the clean water tank 100.

[0040] The first driving component includes a driving block 313 vertically mounted on the horizontal slider 312. The driving block 313 has a driving groove along its length. The first driving component also includes a turntable 330 mounted on the inner wall of the clean water tank 100 via a rotating shaft. The rotating shaft is rotatably mounted on the inner wall of the clean water tank 100 via a bearing. The turntable 330 is fixed to one end of the rotating shaft. A driving column is provided on the side wall of the turntable 330 near its edge, which slides in the driving groove. The rotation of the rotating shaft can drive the turntable 330 to rotate, thereby causing the driving column to rotate and press against the side wall of the driving groove. This drives the horizontal slider 312 to reciprocate within the horizontal slide groove 411, thereby driving the swing frame 310 to reciprocate horizontally within the clean water tank 100, thus causing the fabric to swing.

[0041] In this embodiment, a lower mounting plate 420 is provided inside the clean water tank 100. A vertical sliding groove 421 is provided on the lower mounting plate 420 along the vertical direction. A vertical slider is provided on the side wall of the push frame 320, which slides in the corresponding vertical sliding groove 421. The vertical slider slides in the vertical sliding groove 421 so that the push frame 320 is vertically slidably installed inside the clean water tank 100.

[0042] The second driving component includes a rotating rod 340 rotatably disposed within the clean water tank 100. Hinges 341 are provided at both ends of the rotating rod 340. A hinge rod 350 is hinged to one end of each hinge rod 341, and the other end of the hinge rod 350 is hinged to a corresponding vertical slider. Specifically, the hinge rod 341 includes opposing rods, with one end of each rod connected by a connecting rod. One end of the hinge rod 350 is located between the rods, and the connecting rod passes through one end of the hinge rod 350 to achieve [the desired effect]. The hinge rod 350 is hinged to the hinge member 341; a hinge shaft is provided on the vertical slider, which passes through the other end of the hinge rod 350, thereby realizing the hinge connection of the hinge rod 350 on the vertical slider; with the above structure, the rotation of the rotating rod 340 can drive the hinge member 341 to rotate, so that the hinge rod 350 rotates and pulls the vertical slider to move up and down along the vertical slide groove 421, thereby driving the push frame 320 to move back and forth vertically in the clean water tank 100, so that the swinging fabric is straightened at intervals.

[0043] In this embodiment, the two ends of the rotating rod 340 are rotatably mounted on the side wall of the clean water tank 100 via bearings. In order to realize the rotation of the rotating rod 340, a motor 200 for driving the rotating rod 340 to rotate is provided on the outer side wall of the clean water tank 100.

[0044] In this embodiment, in order to realize the rotation of the shaft, the rotating rod 340 is provided with a first sprocket 342, the shaft is provided with a second sprocket 360, and a chain 370 is sleeved between the first sprocket 342 and the second sprocket 360. Through the above structure, the rotation of the rotating rod 340 can drive the shaft to rotate, so that the swing component 130 and the push component 140 work at the same time.

[0045] In this embodiment, the dewatering assembly 150 includes a dewatering frame 510 disposed on the clean water tank 100. The dewatering frame 510 is provided with a fixed roller 520 and a movable roller 530 that can be raised and lowered. The fabric passes between the fixed roller 520 and the movable roller 530.

[0046] In this embodiment, the movable roller 530 is rotatably mounted on the bracket. The movable roller 530 moves up and down within the dewatering frame 510 to adjust the distance between the movable roller 530 and the fixed roller 520, thereby controlling the squeezing force of the two rollers on the fabric and controlling the moisture content of the output fabric. Specifically, in order to realize the lifting and lowering of the movable roller 530, the dewatering frame 510 is provided with a cylinder 511 for driving the movable roller 530 to lift and lower.

[0047] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
