[0001] The utility model relates to the technical field of non-woven fabric preparation, in particular to a device for preparing stain-resistant non-woven fabric. Background Art

[0002] Non-woven fabric is a kind of fabric that does not require spinning and weaving. It is formed by directional or random arrangement of textile short fibers or filaments to form a fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods. Stain-resistant non-woven fabric is one of many non-woven fabrics. Stain-resistant non-woven fabric needs to smooth its wrinkled area during the winding process. The common smoothing method is manual operation, which is time-consuming and labor-intensive.

[0003] The technical solution disclosed in the Chinese patent with authorization announcement number CN220704061U can easily smooth out wrinkled non-woven fabrics by setting up horizontal plates, support legs, bracket blocks, rollers, L-shaped support rods, top plates, cylinders, U-shaped plates, bidirectional screws, guide rods, motors and smoothing plates. The staff does not need to smooth the wrinkles manually, so it saves time and effort and has high efficiency.

[0004] However, the device still has some shortcomings: in the process of smoothing the wrinkled area of ​​the non-woven fabric, the device lacks a structure for ironing the non-woven fabric, and the wrinkles are easy to recover after the smoothing plate is separated from the non-woven fabric. In addition, the movement of the device is cumbersome and the smoothing efficiency of the non-woven fabric is low. Utility Model Content

DETAILED DESCRIPTION

[0026] Embodiment 1

[0027] like Figure 1-Figure 4 As shown, a stain-resistant non-woven fabric preparation device proposed by the utility model includes a frame 1, a liquid pump 7, a guide roller 8, a bracket 10, a one-way control component and a drive component. A storage tank 101 is arranged on the frame 1, and a sealing plate 2 for closing the opening of the storage tank 101 is arranged on the frame 1. A plurality of partitions 3 are staggered in the storage tank 101 to form a serpentine channel in the storage tank 101. The two ends of the serpentine channel are respectively connected to the return pipe 5 and the feed pipe 6, the return pipe 5 is connected to the thermostat 4, the feed pipe 6 is connected to the output end of the liquid pump 7, and the input end of the liquid pump 7 is connected to the thermostat 4. A temperature sensor, a refrigeration component and a heating component are arranged in the thermostat 4, and a control component is arranged on the thermostat 4. The temperature sensor, the heating component and the refrigeration component are all electrically connected to the control component. The liquid pump 7 circulates and connects the storage tank 101 and the thermostat 4 to keep the medium in the storage tank 101 at a constant temperature. Two guide rollers 8 are respectively located on both sides of the storage tank 101 and are rotatably connected to the frame 1. The guide rollers 8 on both sides are connected by transmission through a conveyor belt 9, and the conveyor belt 9 is slidably connected to the sealing plate 2. The bracket 10 is slidably connected to the movable plate 12. Two groups of connecting rods 14 are symmetrically and rotatably arranged at the bottom of the movable plate 12. The two groups of connecting rods 14 are rotatably connected to a pressure roller 15. A gear lever 19 for limiting the reset angle of the connecting rod 14 is arranged at the bottom of the movable plate 12. The one-way control component includes but is not limited to a ratchet 17 and a ratchet 18. The pressure roller 15 is connected to the rotating shaft 16, the rotating shaft 16 is rotatably connected to the connecting rod 14, the ratchet 17 is connected to the rotating shaft 16, the ratchet 18 is elastically connected to the connecting rod 14, and the ratchet 18 is unidirectionally conductively matched with the ratchet 17. The one-way control component connects the connecting rod 14 and the pressure roller 15 so that the pressure rollers 15 on both sides rotate only when they are close to each other along the surface of the non-woven fabric. The driving assembly includes but is not limited to a hydraulic cylinder 13 , a cylinder body of the hydraulic cylinder 13 is connected to the bracket 10 , and a push rod of the hydraulic cylinder 13 is connected to the movable plate 12 , and the hydraulic cylinder 13 drives the movable plate 12 to rise and fall.

[0028] In this embodiment, the non-woven fabric is transmitted via the conveyor belt 9. Since the conveyor belt 9 needs to maintain good support when the pressure roller 15 presses down the non-woven fabric, the lower surface of the upper horizontal end of the conveyor belt 9 is slidably connected to the upper surface of the sealing plate 2, and the friction between the conveyor belt 9 and the sealing plate 2 generates heat. At this time, the liquid pump 7 is started, and the liquid pump 7 circulates and extracts the constant temperature medium in the constant temperature box and injects it into the serpentine channel, and then refluxes into the constant temperature box 4 through the reflux pipe 5. The temperature of the medium is maintained within a certain range under the action of the heating component and the refrigeration component. In order to prevent the wrinkles of the non-woven fabric from rebounding after being smoothed, the temperature range is controlled at 100-120 degrees Celsius. The medium in the serpentine channel keeps the temperature of the sealing plate 2 within the range, and then the temperature of the non-woven fabric is controlled within the range under the action of the sealing plate 2. When the wrinkled area of ​​the non-woven fabric moves to below the movable plate 12, the hydraulic cylinder 13 is started to press the movable plate 12 downward, and the pressure rollers 15 on both sides slide down synchronously and contact the surface of the non-woven fabric. Then the movable plate 12 continues to slide down, and the pressure rollers 15 on both sides open synchronously. In the process of increasing the spacing along the surface of the non-woven fabric, the rotating shaft 16 of the pressure roller 15 is restricted by the unidirectional rotation of the ratchet 17 and the ratchet 18 and remains stationary. At this time, the pressure roller 15 will not rotate, and it directly smoothes the non-woven fabric. After the non-woven fabric is smoothed, the hydraulic cylinder 13 pulls up the movable plate 12, so that the pressure rollers 15 on both sides approach each other. In the process of the pressure rollers 15 approaching, the ratchet 18 does not limit the rotation of the ratchet 17. Therefore, the pressure roller 15 is in a state of rotation and approaching, and will not affect the flat non-woven fabric.

[0029] Embodiment 2

[0030] like Figure 1 As shown, the utility model proposes a stain-resistant non-woven fabric preparation device. Compared with the first embodiment, a visual camera 11 is arranged on the side of the bracket 10 close to the feeding end of the conveyor belt 9, the detection end of the visual camera 11 faces the conveyor belt 9, and the visual camera 11 is electrically connected to the control component, and the control component is electrically connected to the driving component.

[0031] In this embodiment, the visual camera 11 directly shoots and compares the non-woven fabric in the transmission state to automatically identify the wrinkle position of the non-woven fabric. When the visual camera 11 detects wrinkles in the non-woven fabric, the non-woven fabric is suspended from rolling when the wrinkle position is transmitted to the bottom of the movable plate 12, and then the equipment automatically starts the smoothing program.

[0032] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
