Description

Technical Field

[0001] The utility model relates to the technical field of cloth finishing, in particular to a cloth shrinkage production line. Background Art

[0002] In the production process of fabric, it needs to go through weaving, scouring, dyeing, finishing and other processes. In the above processes, the fabric will be subjected to strong mechanical tension, which makes the fabric form an unstable state of weft contraction and warp elongation, resulting in various stresses inside the fabric. If these stresses are not eliminated in advance, the subsequent fabric may become smaller in size, distorted in shape and other problems after being cut and sewn into clothing. For this reason, the fabric needs to be pre-shrunk. The pre-shrunk fabric can eliminate potential stress and restore the fabric to a relatively stable state.

[0003] Pre-shrinkage treatment requires the use of a fabric shrinkage production line, but the fabric shrinkage production lines currently on the market have problems such as incomplete shrinkage and poor shrinkage effect. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in this embodiment can be understood according to the specific circumstances. The directional words that appear in this embodiment are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of this embodiment changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0031] The feeding mechanism 1 is used to feed the fabric to the production line. The structure and working principle of the feeding mechanism 1 are prior art, so its structure will not be described in detail in this application.

[0032] The steam box 2 is used to steam the cloth. The steam box 2 can pre-shrink and shape the cloth, increase humidity and softness, eliminate static electricity and improve the unwinding effect. The structure and working principle of the steam box 2 are prior art, and the existing steam boxes on the market can be directly integrated into the production line. However, the present embodiment also improves the structure of the steam box 2, as described below.

[0033] The bubble scraper 3 is used to scrape bubbles from the fabric. The bubble scraper 3 is added in front of the pre-shrinking machine 5 to promptly remove bubbles generated in the fabric. After the bubbles are removed, the fabric can be better in contact with the pre-shrinking liquid, so that the fabric absorbs the pre-shrinking liquid more evenly, thereby improving the pre-shrinking effect and making the fabric size more stable; after the bubbles are removed, the fabric surface can be kept flat and smooth. The structure and working principle of the bubble scraper 3 are existing technologies, and the existing bubble scrapers on the market can be directly integrated into the production line, so its structure is no longer described in detail in this application.

[0034] The skew machine 4 is used to perform skew treatment on the fabric. The skew treatment is mainly to eliminate the twisting and skewing stress of the weft yarn inside the fabric, ensure the dimensional stability of the clothing, adjust the weft value of the fabric, so as to improve the quality of the fabric and reduce the problems of the fabric in the subsequent processing and use. The structure and working principle of the skew machine 4 are existing technologies, and the existing skew machines on the market can be directly integrated into the production line, so its structure is no longer described in this application.

[0035] The preshrinking machine 5 is used to preshrink the fabric; the structure and working principle of the preshrinking machine 5 are prior art, and the existing preshrinking machines on the market can be directly integrated into the production line, so its structure is no longer described in detail in this application.

[0036] The air dryer 6 is used to air dry the fabric; the air dryer 6 is provided with an air drying drum 61 and ventilation equipment, the air drying drum 61 is heated by steam or an electric heater, the moisture on the surface of the fabric evaporates when the fabric passes by the air drying drum 61, and the ventilation equipment sends away the evaporated moisture. The structure and working principle of the air dryer 6 are prior art, and the existing air dryers on the market can be directly integrated into the production line, but the present embodiment also makes improvements to the air dryer 6, as described below.

[0037] The cooling mechanism 7 is used to cool the fabric, which helps to fix the size of the pre-shrunk fabric and prevent the fabric from deforming or shrinking again during subsequent processing or storage. The structure and working principle of the cooling mechanism 7 are prior art, and the existing cooling mechanism on the market can be directly integrated into the production line, but the present embodiment also makes improvements to the cooling mechanism 7, as described below.

[0038] The material receiving mechanism 8 is used to send the fabric out of the production line and stack it up. The structure and working principle of the material receiving mechanism 8 are prior art, so its structure will not be repeated in this application.

[0039] Through the above-mentioned structural setting, this kind of fabric shrinkage production line first performs steam moistening, scraping and slanting processes in sequence before pre-shrinking the fabric, and then performs pre-shrinkage after completing the above-mentioned processes. Compared with the existing technology, the above-mentioned pre-treatment can make the pre-shrinkage effect better and the fabric shrinkage more thoroughly; after the pre-shrinkage step, the fabric is air-dried and cooled, so that the temperature of the fabric finally sent out is lower, the size of the fabric after pre-shrinkage is fixed, the staff can more easily handle the sent out fabric, and the comfort of the working environment is improved.

[0040] In this embodiment, if Figure 2 As shown, a water tank 21 is provided at the bottom of the steam box 2, and a heating pipe 22 is provided in the water tank 21. The heating pipe 22 is used to heat the water in the water tank 21 to generate water vapor. Preferably, a plurality of cloth conveying rollers 23 for conveying cloth are provided in the steam box 2, and a water supply pipe 24 is connected to the steam box 2. The water outlet of the water supply pipe 24 is located below the cloth conveying roller 23, and the water supply pipe 24 replenishes water into the water tank 21. Preferably, an oil heating cover plate 25 is provided at the top opening of the steam box 2, and the oil heating cover plate 25 blocks the top opening of the steam box 2. A hot oil cavity 251 is provided inside the oil heating cover plate 25, and an electric heating pipe 252 is provided in the hot oil cavity 251. The cross-sectional shape of the oil heating cover plate 25 is an inverted "V" shape, and the two inclined surfaces of the inverted "V" shape are respectively located on both sides of the cloth conveying direction. Preferably, the temperature of the bottom surface of the oil-heated cover plate 25 is higher than 100°C when the steamer 2 is steaming the cloth. By setting the oil-heated cover plate 25 with a temperature higher than the temperature of the water vapor, the temperature of the top cover of the entire steamer 2 is sufficiently high to prevent the water vapor from contacting the low-temperature top cover to become condensed water and then dripping into the cloth to affect the quality of the cloth. In addition, the method of heating the oil with the electric heating pipe 252 is safer and the temperature is better controlled. The cross-sectional shape of the oil-heated cover plate 25 is an inverted "V" shape, and the two inclined surfaces of the inverted "V" shape are respectively located on both sides of the cloth conveying direction, so that even if condensed water is formed, the condensed water will flow down along the two sides of the oil-heated cover plate 25, and the path of flowing down is to flow down from both sides of the cloth conveying direction, and will not drip onto the cloth, nor will it flow onto the cloth from the cloth inlet and outlet of the steamer 2.

[0041] In this embodiment, the air dryer 6 is configured to have only one air drying drum 61, and the diameter of the air drying drum 61 is greater than 1.8 meters. Preferably, the diameter of the air drying drum 61 is 2 meters. Providing a larger air drying drum 61 can increase the contact area between the cloth and the air drying drum 61.

[0042] In this embodiment, if Figure 3As shown, the cooling mechanism 7 includes a plurality of water-cooling cylinders 71 for the cloth to pass through in sequence. The water-cooling cylinders 71 are hollow structures and have a water-cooling cavity formed inside. The water-cooling cylinders 71 are connected in sequence. The water-cooling cylinder 71 closest to the end of the cloth shrinking production line is connected to a water inlet pipe 711, and the water-cooling cylinder 71 closest to the front end of the cloth shrinking production line is connected to a water outlet pipe 712. When in use, normal temperature water is input into the water-cooling cylinder 71, and the normal temperature water cools the water-cooling cylinder 71, and the water-cooling cylinder 71 cools the cloth. At the same time, the coldest normal temperature water is first input into the water-cooling cylinder 71 closest to the end of the cloth shrinking production line, so that the temperature of the water-cooling cylinder 71 closest to the end of the cloth shrinking production line is the lowest. The cooling mechanism 7 further includes a controller 713, a temperature sensor 714 and a water pump 715. The water pump 715 is arranged in the water path of the cooling mechanism 7. The temperature sensor 714 is arranged in the water cooling cylinder 71 closest to the end of the fabric shrinking production line. The temperature sensor 714 is connected to the controller 713 for communication. The water pump 715 is electrically connected to the controller 713 and is controlled by the controller 713. When the temperature sensor 714 detects that the temperature of the water cooling cylinder 71 is too high, the temperature sensor 714 transmits a signal to the controller 713. The controller 713 controls the water pump 715 to work, so as to renew the normal temperature water in the water cooling cylinder 71 and cool down the water cooling cylinder 71. Preferably, when the fabric shrinking production line is working, the temperature of the water cooling cylinder 71 closest to the end of the fabric shrinking production line is lower than 30°C to meet the cooling requirements.

[0043] In summary, this kind of fabric shrinkage production line can solve the problems of incomplete shrinkage and poor shrinkage effect of shrinkage machines in the prior art.

[0044] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the preferred technical solutions of the utility model, rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solutions of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the utility model.
