Description

Technical Field

[0001] The utility model relates to a textile fabric impregnation device, in particular to a suction type fabric impregnation device and a textile production combined machine. Background Art

[0002] In the textile printing and dyeing industry, various chemical auxiliaries are required for impregnation before each wet treatment process of textiles. There are usually two types of existing impregnation devices: one relies on the fabric to repeatedly penetrate through the impregnation tank multiple times, so that the chemical medium penetrates into the fabric fibers; the other relies on multiple rollers to repeatedly squeeze the fabric under the liquid, so that the chemical medium penetrates into the fibers. However, due to the high density of some fabrics, the large size of chemical medium particles, and the presence of a water-repellent layer on the fabric surface, even though repeated penetration and repeated squeezing are carried out, there are still problems of incomplete impregnation. Repeated penetration also has problems such as a large tank body, a large amount of chemical liquid, and waste and pollution.

[0003] In the prior art, CN101550654A discloses an ultrasonic high liquid-carrying impregnation device, which relates to the technical field of textile printing and dyeing, especially the impregnation process equipment technology field before wet treatment processing. In the present invention, a cloth guiding roller is arranged in the tank body, and a cloth feeding roller and a cloth discharging roller are respectively arranged at both ends above the tank body. Its feature is that an ultrasonic generator is arranged in the tank body. Although ultrasonic waves can make the chemical medium vibrate and penetrate into the fibers more quickly, the effect is very little. It is still necessary to impregnate the fabric multiple times synchronously in the impregnation process flow. The overall impregnation chemical reagent required for this impregnation device is very large, and multiple groups of cloth guiding rollers need to be arranged, resulting in a large floor area for the entire impregnation process, low impregnation efficiency, high cost, and serious waste of chemical reagents. Summary of the Utility Model

[0004] Purpose of the utility model: The first purpose of the present utility model is to provide a suction type fabric impregnation device that can greatly reduce the impregnation chemical reagent, improve the utilization rate of resources, and can achieve the maximum impregnation effect in a limited impregnation space.

The cloth guiding roller at the lowest position in the left cloth guiding roller group guides the cloth surface into the water tank. A submersible suction device for sucking and impregnating the cloth surface closely is also arranged below the liquid level of the water tank. A nozzle connected to the submersible suction device and used for secondarily flushing the impregnated cloth surface is arranged above the mesh roller.

[0019] The technical solution of the utility model will be further described below with reference to the drawings.

[0020] Example 1

[0021] As Figure 1 shown, a suction-type fabric impregnation device includes an impregnation box body 1, which has a fabric inlet and a fabric outlet. A mesh roller 4 is provided in the center of the impregnation box body 1, and the fabric surface is wound around the mesh roller 4. The mesh roller 4 is driven by a driving motor 20 and can drive the fabric surface to move at a high speed. A water tank 2 is provided at the bottom of the impregnation box body 1. Each water tank 2 is in a U-shaped or V-shaped class. In the impregnation box body 1, a left fabric guide roller group 3, a mesh roller 4 and a right fabric guide roller 5 are arranged along the fabric transportation direction. The fabric guide roller at the lowest position in the left fabric guide roller group 3 is immersed in the chemical reagent liquid in the water tank. The left fabric guide roller group 7 includes 3 fabric guide rollers distributed in a triangle. The submersible suction device 9 is located below the liquid level of the water tank 2, and the suction port of the submersible suction device 9 is closely attached to the fabric surface in the water tank 2. As Figure 2 shown, the submersible suction device includes a water suction pipe 901 and a water pump 7. The bottom end of the water suction pipe 901 is connected to a nozzle 6 located above the mesh roller 4 through a water pipe and a water pump 7 provided on the water pipe. The water suction pipe 901 is a square pipe. Uniformly arranged water suction ports 902 are provided on the side surface of the water suction pipe 901 facing the fabric. The water suction ports 902 are kidney-shaped holes. Connecting flanges 903 are welded at both ends of the water suction pipe 901. One end of the water suction pipe 901 is sealed, and the other end is connected to the water pump 7 through the connecting flange 903. A total of 2 groups of nozzles 6 are provided above the mesh roller 4, and the 2 groups of nozzles 6 are used for secondary flushing of the impregnated fabric surface.

[0022] A water circulation interface 8 is provided at the bottom end of the water tank 2, and the water circulation interface 8 is connected to the nozzle 6 through a pipeline. A filter 10, a water pump 11 and a heat exchanger 12 are provided on the pipeline in sequence according to the direction of liquid flow. When the equipment is working normally, the water pump 11 will suck the sewage in the water tank 2 into the pipeline. First, the sewage is filtered by the filter 10 arranged on the water pipe, and then the heat exchanger 12 performs heat exchange treatment on the filtered liquid, and the impregnated cloth surface is flushed for the second time through the nozzle 6, and then flows into the water tank 2 again. The warm water that has been retained in the water tank 2 can enhance the impregnation effect. The temperature in the water tank 6 is controlled by detecting the water temperature through the temperature sensor 13 and then transmitting the temperature data to the controller. The controller will control the heat exchanger 12 according to the temperature data to control the liquid temperature at the set temperature. The upper edge of the water tank 2 near the cloth inlet side extends obliquely downward to form a groove. The bottom of the water tank 2 is also provided with a drain port 15. After all equipment stops running, all sewage in the water tank 2 is discharged through the drain port 15 at the bottom of the water tank 2. The impregnation box 1 is also provided with a window 21, which is convenient for observing the internal situation of the impregnation box 1. A liquid level sensor 14 is also provided at the bottom of the water tank 2. When the liquid level sensor detects that the liquid in the water tank 2 is at the lower limit setting value, the impregnation chemical reagent is added to the water tank 2. When the liquid level detected by the liquid level sensor is lower than the setting value, the controller starts to replenish water, and the external water tank replenishes water to the filter 10; when the liquid level detected by the liquid level sensor exceeds the setting value, the controller stops replenishing water; the chemical reagent replenishment is completed by the external feeding system, which calculates the feeding speed according to the amount of cloth to be impregnated, and controls the feeding pump to evenly add material to the filter 10.

[0023] The cloth surface is guided into the water tank 2 by the cloth guide roller for immersion, and then the cloth surface is driven to be close to its surface through the suction effect of the water pump 7 in the underwater suction device 9 on the liquid. Since the cloth surface is always moving at a high speed in the immersion device and pressure is generated during the suction process, the side of the suction pipe 901 of the underwater suction device 9 facing the cloth will produce relative movement and friction with the cloth surface, thereby making the surface of the cloth smooth and flat. When the underwater suction device 9 is working, the liquid in the water tank 2 will pass through the cloth surface and then be sucked into the water suction pipe 901. The liquid sucked into the water suction pipe 901 is sucked and transported to the nozzle 6 located on the top of the impregnation box 1 by the water pump 7. The nozzle 6 will perform secondary flushing and immersion on the cloth surface covering the mesh roller 4. The cloth surface is driven by the mesh roller 4 and enters the right cloth guide roller 5 on the right side through the guiding effect of the cloth guide roller group, and then is discharged from the cloth outlet.

[0024] After coming out of the suction type cloth impregnation device, the cloth will enter the rolling chamber 16 of the next process, and pass through the cloth guide roller 17, bending roller 18 and feeding roller 19 in the rolling chamber 16 in turn. The cloth surface is guided by the cloth guide roller 17. In order to prevent the cloth surface from wrinkling, the bending roller 18 will flatten the cloth surface, and then enter the feeding roller 19, where it will be squeezed and flushed again. The feeding roller 19 is composed of a rubber roller located at the top and a steel roller located at the bottom. The steel roller at the bottom is driven by a motor to pull the cloth surface to move at high speed. The extruded cloth surface will be guided by the cloth guide roller to enter the next process.
