Description

Technical Field

[0001] This utility model belongs to the field of wool fabric processing technology, specifically relating to a surface treatment device for intermittently felted wool fabric. Background Technology

[0002] Fulling is an important wool fabric treatment process designed to improve the quality and appearance of wool fabrics. It offers the following advantages: Improved fabric quality: Fulling makes wool fabrics denser, increasing their thickness and strength, thereby improving warmth and elasticity; Enhanced appearance: Fulled wool fabrics have a layer of fluff on the surface, making them more beautiful, softer to the touch, and with a more muted color; Concealing imperfections: The fluff produced by fulling can soften and conceal some of the original imperfections in the wool fabric, making them less noticeable.

[0003] Therefore, in order to achieve the purpose of felting and to better control the area and shape of the felting region, a surface treatment device for intermittent felting of wool fabric is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a surface treatment device for intermittently felted wool fabric.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a surface treatment device for intermittently felted wool fabric, including a machine housing, a conveying pipe connected to the back of the machine housing, a water tank installed at the bottom of the machine housing, a water heater and an infusion pipe installed on the inner wall of the machine housing, a spraying device installed on the inner wall of the middle section of the conveying pipe, a hot air device installed on the top of the inner wall of the front section of the conveying pipe, a first linear guide rail module installed on the inner wall of the front section of the conveying pipe, and a second linear guide rail module installed on the moving end of the first linear guide rail module. The mobile end of the assembly is equipped with a bracket, inside which a storage tank is installed. A nozzle is installed at the bottom of the bracket. An installation frame is slidably installed on the side wall of the conveying pipe. A first motor with rollers is installed at the bottom of the installation frame. A second motor is installed at one end inside the installation frame. A pressure roller is rotatably installed on the inner wall of the installation frame. An assembly frame is installed on the top of the installation frame. An electrical control device is installed on the side of the assembly frame. An electromagnet is installed inside the assembly frame. A spring is installed on the outer surface of the electromagnet. A pressure plate is installed at the bottom end of the spring.

[0006] Furthermore, the inner wall of the conveying pipe is equipped with a slide rail that is compatible with the rollers mounted on the first motor. Through the above-mentioned configuration, the smooth movement of the mounting components on the mounting frame in the conveying pipe is achieved by the cooperation between the rollers mounted on the first motor and the slide rail.

[0007] Furthermore, the middle section of the conveying pipe is semi-circular, and there are two spraying devices symmetrically distributed in the middle section of the conveying pipe. Through the above settings, combined with the number of spraying devices, the conveying pipe is divided into two processing areas.

[0008] Furthermore, the number of nozzles is no less than four, and all four nozzles are connected to the storage tank. With the above configuration, the solution in the storage tank can be sprayed out through the nozzles.

[0009] Furthermore, one end of the pressure roller is connected to the output end of the second motor, and an iron block located directly below the electromagnet is installed on the top of the pressure plate. With the above configuration, the pressure roller can transport the fabric by being driven by the second motor. When the electromagnet is energized, the pressure plate no longer presses on the fabric using magnetic force, so that the pressure roller can transport the fabric.

[0010] Furthermore, the electrical control device is electrically connected to the first motor, the second motor, and the electromagnet. With the above-mentioned configuration, the operation of the electrical appliances can be controlled by the electrical control device in conjunction with the processing progress.

[0011] The beneficial effects of this utility model are as follows: This utility model combines multiple processing methods, spraying water-soluble PVC adapted to the process flow onto the fabric surface, allowing the exposed areas to be used for felting. Furthermore, combined with the movement of the linear guide module, the area and shape of the exposed areas can be determined according to requirements, making the felting process more intelligent and personalized, and achieving automated processing. This reduces manual intervention and improves production efficiency. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] like Figures 1 to 5 As shown, this embodiment of a surface treatment device for intermittently felted wool fabric includes a housing 1. The front of the housing 1 has a window for removing the wool fabric, and the back of the housing 1 is connected to a conveying pipe 2. The conveying pipe 2 plays a crucial role in conveying the wool fabric throughout the device, transferring the fabric from one processing stage to another. A water tank 3 is installed at the bottom of the housing 1. A water heater 4 and a liquid delivery pipe 5 are installed on the inner wall of the housing 1. The water heater 4 injects hot water of a suitable temperature into the water tank 3 through water pipes to meet the requirements of different processing techniques, while the liquid delivery pipe 5 is responsible for delivering the reagents used during processing to the water tank 3.

[0016] like Figure 3 As shown, a spraying device 6 is installed on the inner wall of the middle section of the conveying pipe 2. The middle section of the conveying pipe 2 is semi-circular. There are two spraying devices 6 symmetrically distributed in the middle section of the conveying pipe 2. When the fabric passes through the middle section of the conveying pipe 2, the spraying devices 6 at different positions will spray the reagents used evenly on the surface of the fabric. The spraying device 6 near the storage tank 11 is used to spray descaling agents, such as a solution of sodium dichloroisocyanurate (DCCA) 0.3–0.5% owf, pH 4.5–5. The other spraying device 6 is mainly used to spray a solution such as sodium bisulfite, mainly to neutralize the descaling agent used earlier, so that the chlorine emission can meet the standards. This forms different treatment sections in the conveying pipe 2, preparing for subsequent processing steps such as fulling.

[0017] like Figure 4 As shown, a hot air device 7 is installed on the top of the inner wall of the front section of the conveying pipe 2. The function of the hot air device 7 is to preheat and dry the fabric before it enters the subsequent processing stage. By blowing hot air, excess moisture on the surface of the fabric can be removed, while the temperature of the fabric is increased, making the fabric more resistant to subsequent processing. The hot air temperature and wind speed of the hot air device 7 can be adjusted according to different fabric characteristics and processing requirements to achieve the best processing effect.

[0018] like Figure 4As shown, a first linear guide module 8 is installed on the inner wall of the front section of the conveying pipe 2, and a second linear guide module 9 is installed at the moving end of the first linear guide module 8. The combined use of these two linear guide modules provides flexible control for the movement of subsequent components. A bracket 10 is installed at the moving end of the second linear guide module 9, and a storage tank 11 is installed inside the bracket 10. The storage tank 11 contains a water-soluble PVC solution, which, while providing protection, can be removed with only 40°C hot water. Its characteristics are suitable for subsequent processing steps. A nozzle 12 is installed at the bottom of the bracket 10. There are at least four nozzles 12, and all four nozzles 12 are connected to the storage tank 11. The storage tank 11 is used to store a special treatment agent. When the fabric passes under the nozzle 12, the water-soluble PVC is sprayed out from the nozzle 12 for further treatment of the fabric. The first linear guide module 8 and the second linear guide module 9 can control the movement of the bracket 10, thereby enabling the nozzles 12 to spray the fabric comprehensively and evenly.

[0019] like Figure 5 As shown, a mounting frame 13 is slidably mounted on the side wall of the conveying pipe 2, and a first motor 14 with rollers is mounted on the bottom of the mounting frame 13. A slide rail adapted to the rollers mounted on the first motor 14 is installed on the inner wall of the conveying pipe 2. The first motor 14 drives the mounting frame 13 to slide along the side wall of the conveying pipe 2 by the rollers rolling on the slide rail. A second motor 15 is mounted at one end inside the mounting frame 13, and a pressure roller 16 is rotatably mounted on the inner wall of the mounting frame 13, with one end of the pressure roller 16 connected to the output end of the second motor 15. When the second motor 15 starts, it drives the pressure roller 16 to rotate, allowing the pressure roller 16 to convey the fabric.

[0020] like Figure 5 As shown, an assembly frame 17 is mounted on the top of the mounting frame 13, and an electronic control device 18 is mounted on the side of the assembly frame 17. The electronic control device 18 contains an incremental encoder electrically connected to the first motor 14, used to record the movement distance. This allows the electronic control device 18 to switch circuits to power the second motor 15 and the electromagnet 19 before the mounting frame 13 moves to the water tank 3. The electromagnet 19 is installed inside the assembly frame 17, and a spring 20 is mounted on the outer surface of the electromagnet 19. A pressure plate 21 is mounted on the bottom end of the spring 20. An iron block is mounted on the top of the pressure plate 21, located directly below the electromagnet 19. The electronic control device 18 is electrically connected to the first motor 14, the second motor 15, and the electromagnet 19, allowing for precise control of these components.

[0021] The working principle of this embodiment is as follows: the wool fabric to be shrunk is placed under the pressure roller 16 and the pressure plate 21, and the wool fabric is driven by the rollers installed on the first motor 14 to pass through the hot air device 7, the nozzle 12 and the spraying device 6 in sequence. When the wool fabric moves to the top of the water tank 3, the electromagnet 19 is energized and attracts the pressure plate 21 through magnetic force. The second motor 15 is also energized, which drives the pressure roller 16 to rotate and send the wool into the water tank 3 for subsequent processing.

[0022] When the wool passes through the hot air device 7, it is treated by hot air and then conveyed to the nozzle 12. In conjunction with the area that needs to be felted, the nozzle 12 sprays the water-soluble PVC solution in the storage tank 11 onto the fabric with the action of the linear guide module, so that the water-soluble PVC solution forms a film on the fabric, and the area not covered by the film is the felting area. When passing through the first spraying device 6, the spraying device 6 sprays descaling agent onto the wool fabric to descale the exposed areas, making the exposed areas easier to feel, while the scales of the wool in the covered areas are intact, thereby achieving the effect of intermittent felting. When the wool fabric passes through the second spraying device 6, the agent sprayed onto the wool fabric is a neutralizing agent to reduce pollutant emissions. Subsequently, when the wool is in the water tank 3, hot water of appropriate temperature is introduced through the water heater 4, and a shrinking agent is sent into the water tank 3 through the infusion pipe 5 to perform felting treatment on the wool fabric.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
