Description

Technical Field

[0001] The utility model relates to the field of cotton and linen fabric processing equipment, in particular to a singeing device for hemp and cotton woven fabrics. Background Art

[0002] In recent years, cotton and linen have attracted more and more attention from people, and a wave of cotton and linen literary and artistic trends has been set off. In today's era where people pay more and more attention to the quality of life and environmental protection and health, cotton and linen as natural fabrics will undoubtedly become a fierce fashion hotspot. Cotton is soft and comfortable, linen is breathable and wear-resistant, and cotton and linen blended fabrics are favored by all kinds of clothing people. Cotton and linen fabrics give people a feeling of comfort and fashion. Cotton and linen are the general term for cotton and linen blended fabrics. Cotton and linen blends refer to textile products made by mixing cotton and linen in a certain proportion, and have the characteristics of both linen and cotton. Cotton and linen blends have the advantages of environmental protection, breathability, comfort, good drape, and comfortable wearing. They have good elasticity and wear resistance in dry and wet conditions, stable size, small shrinkage rate, and are upright, not easy to wrinkle, easy to wash, and quick-drying. The advantages and disadvantages of the two complement each other. Moreover, it is woven with all-natural fibers, low-carbon and environmentally friendly, which is consistent with the current international textile and clothing trends. Therefore, it is very suitable for clothing and home textile fabrics, and has become the best choice for summer clothes.

[0003] At present, the most widely used cotton and linen fabrics are mainly linen cotton fabrics and hemp cotton fabrics. Compared with linen, hemp is the natural fiber with the best antibacterial effect, and the fiber strength is high, and the moisture conduction and breathability are better, so hemp cotton fabric has become a more popular fabric today. Since cotton and linen fabrics can be made by weaving or knitting, cotton and linen fabrics can be divided into two categories: woven cotton and linen and knitted cotton and linen. Compared with knitted fabrics, hemp cotton woven fabrics have a relatively flat surface, stable dimensions, and natural drape without sagging. The fabric is firm and easy to dye and process, and is suitable for washing and dry cleaning, so it is suitable for making more structured clothing. From the raw materials, woven fabrics include cotton, linen, silk, wool, chemical fiber and blended fabrics, etc. The price is relatively cheap, so hemp cotton woven fabrics are widely used.

[0004] According to the basic production process of cotton and linen cloth, cotton and linen grey cloth needs to be treated with anti-pilling finishing before dyeing and finishing. Currently, there are two main methods: bio-enzyme polishing and mechanical singeing. Bio-enzyme polishing has a more lasting finishing effect and good anti-pilling effect, but the process conditions must be strictly controlled, otherwise it will cause enzyme inactivation or fiber damage and weight loss. Mechanical singeing uses singeing and shearing to remove the fluff on the surface of the fabric, reducing the fiber heads exposed on the surface of the fabric, making the fabric less prone to pilling. Due to the particularity of hemp fibers, mechanical depilation is more suitable for cotton and linen fabrics than bio-enzyme polishing. The current existing technologies for depilating cotton and linen fabrics and grey cloth are as follows:

[0005] CN 213447676 U discloses a cotton and linen grey cloth singeing device, comprising a machine body, an inner ring groove and a motor, a mounting block is mounted on the machine body, a limiting ring is connected to the mounting block, a first notch is provided on the limiting ring, an inner ring groove is provided on the inner side of the limiting ring, a sliding block is provided at the left end of the limiting ring, a motor is provided at the left end of the sliding block, a handle is mounted on the sliding block, a sliding groove is provided on the lower side of the sliding block, a placing rack is provided at the lower end of the limiting ring, a conveyor belt is provided on the placing rack, a transmission shaft is mounted on the conveyor belt, a heat conducting block is mounted on the inner side of the conveyor belt, and a heater is connected to the heat conducting block. CN 211199748 U discloses a cloth singeing machine for cotton and linen processing and a singeing roller thereof, which specifically relates to the field of textile machinery, and comprises a singeing machine case, a first roller is fixedly mounted on one side of the surface of the singeing machine case, a feed port is provided on one side of the surface of the singeing machine case, a stabilizing block is fixedly mounted on the inner bottom end of the singeing machine case, a second roller is fixedly mounted on the left side of the top end of the stabilizing block, a hydraulic rod is detachably mounted on the left side of the top end of the stabilizing block, a wooden rod is detachably mounted on the top end of the hydraulic rod, a limiting block is movably sleeved on the surface of the wooden rod, and a singeing device is fixedly mounted on the left side of the top end of the stabilizing block.

[0006] Although the above patented technology can improve the surface quality of cotton and linen fabrics after singeing, avoid the adhesion of impurities, and cool the fabrics after singeing, effectively protecting the fabrics from damage, there are still some problems in the singeing and hair removal process for hemp cotton woven fabrics. Since hemp cotton woven fabrics are mainly used for the production of summer clothing such as coats, suits, and trousers, the fabric texture is relatively thin. The degree of singeing needs to be strictly controlled during the singeing process to avoid burning the grey fabric during the singeing process and damaging the grey fabric. In the actual singeing process, in order to ensure that only the fluff is burned without affecting the fabric body, high temperature (favorable for singeing) and fast speed (fabric protection) are required. If the temperature is too low (under-burning), the fluff is not easy to burn clean, the fluff is spherical, and color spots appear during dyeing. If the temperature is too high or the speed is slow (over-burning), the fabric will shrink thermally, resulting in wrinkles and hand-sensing phenomena, and the width will shrink. The main factors affecting the singeing quality of the singeing machine during operation can be summarized as the number of singeing times, the distance (angle) between the singeing machine fire mouth and the fabric, and the flame temperature. Among them, the flame temperature can be regarded as the main factor. Generally speaking, the flame temperature can determine the speed of the singeing machine.

[0007] It is not easy to accurately control the flame in the combustion chamber of the gas singeing machine when it is ejected through the narrow slit of the fire port. If the flame ejection height is too high, it is easy to damage the grey cloth. If it is too short, the temperature is not enough and the singeing effect is poor. Since the hemp cotton woven fabric itself feels relatively hard, the roughness of the fabric is aggravated compared with other woven fabrics, and the hemp cotton woven fabric itself is light and thin, it is very easy to damage the grey cloth during singeing. Therefore, how to accurately adjust the flame ejection state when singeing the hemp cotton woven fabric, and effectively improve the singeing efficiency and singeing quality while avoiding damaging the fabric surface, has always been a difficult problem in the textile field, and has become a problem that technicians in the field of dyeing hemp cotton knitted fabrics are currently urgently trying to solve.

[0030] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 , 2 As shown in Figure 3, a singeing device for hemp-cotton woven fabrics comprises a cloth feeding mechanism 2 arranged in sequence along the conveying direction of the grey cloth 1 for continuously conveying the grey cloth 1 to be singed, a singeing chamber 3 for singeing the conveyed grey cloth 1, an immersion tank 4 for quickly cooling and extinguishing the singed grey cloth 1, a water-squeezing vehicle 5 for controlling the amount of liquid carried by the singed grey cloth after immersion; and a cloth discharging mechanism 6 for conveying the grey cloth 1 after squeezing. A smoke exhaust device 7 is installed above the singeing chamber for timely discharging the exhaust gas in the singeing chamber 3 and the soot particles and impurities generated during the singeing process. Since hemp-cotton woven fabrics are thin fabrics, brushing is not required before singeing.

[0032] The cloth feeding mechanism 2 includes a plurality of cloth feeding rollers 8 for conveying the grey cloth 1 into the singeing chamber 3. The singeing chamber 3 includes a singeing box 9 and a singeing roller 10 arranged in the singeing box 9. A singeing burner 11 is arranged on one side of the singeing roller 10, and a conveying roller assembly 12 for conveying the singed grey cloth 1 into the impregnation tank 4. The singeing burner 11 includes a lower shell 13 having a fuel chamber 12, and an upper shell 14 fixedly connected to the lower shell 13. A first combustion chamber 15 and a first nozzle 16 connected to the first combustion chamber 15 are provided on the upper shell 14. A nozzle body 17 is fixedly connected to the upper shell 14. A second combustion chamber 18 and a second nozzle 19 corresponding to the first combustion chamber 15 and the first nozzle 16 are provided on the nozzle body 17. A gas filling port 20 for filling the fuel chamber 12 with gas is provided on the lower shell 13. The upper shell 14 and the lower shell 13 as well as the upper shell 14 and the nozzle body 17 are fixed by conventional bolts and nuts. A flame adjustment device 21 is arranged in the first combustion chamber 15 to control the uniformity and stability of the flame.

[0033] like Figure 4 , 5 As shown, the flame adjustment device 21 includes a flame adjustment chamber consisting of four side plates 22 and a top plate 23 extending along the width direction of the first combustion chamber 15 and communicating with the fuel chamber 12. A partition plate 26 is installed in the flame adjustment chamber to separate the flame adjustment chamber into a lower adjustment chamber 24 and an upper adjustment chamber 25. A plurality of primary flame outlet holes 27 communicating with the lower adjustment chamber 24 are provided on the partition plate 26, and a plurality of secondary flame outlet holes 28 communicating with the upper adjustment chamber 25 are provided on the top plate 23. Wing plates 29 for fixing the flame adjustment device 21 in the upper housing 14 are symmetrically extended on the outer side wall of the flame adjustment chamber.

[0034] In order to avoid the flame jumping and shaking due to incomplete combustion, and the flame ejection height being too high due to excessive combustion, the lower adjustment chamber 24 of the utility model is arranged in the first combustion chamber 15, the upper adjustment chamber 25 is arranged in the first nozzle 16, and the secondary flame outlet hole 28 is arranged in the horizontal direction of the first nozzle water 16 and is connected to the second combustion chamber 18. The upper adjustment chamber is gradually contracted and arranged in the first nozzle along the setting direction of the first combustion chamber and the first nozzle. The traditional combustion in the first combustion chamber 15 is changed to combustion in the lower adjustment chamber 24. The burning flame and the incompletely burned fuel pass through a number of first-level flame outlet holes 27 to reach the upper adjustment chamber 25. At this time, the flame stays briefly in the upper adjustment chamber 25 through the obstruction of the top plate 23, which assists the incompletely burned fuel to further burn. At the same time, the first-level flame outlet holes 27 opened on the partition 26 and the second-level flame outlet holes 28 opened on the top plate 23 are arranged in a staggered manner along their opening direction. The staggered arrangement structure, with the assistance of the partition 26 and the top plate 23, can allow the flame to fully burn and stay in the lower adjustment chamber 24 and the upper adjustment chamber 25. The staggered arrangement of the first-level flame outlet holes 27 and the second-level flame outlet holes 28 can limit the shape and ejection speed of the flame, so that the flame burns more stably when it reaches the second combustion chamber 18, and the state and temperature are uniform when it is ejected through the second nozzle 19, so that a stable and non-flocculating high-quality flame can be obtained. At the same time, it can prevent the problem of excessive flame during combustion, and reduce the defects of excessive flame combustion and excessive ejection height. The flame stays more in the flame adjustment device 21, which also increases the burning time, while saving fuel and improving the utilization rate of fuel. While the combustible gas burns more fully, the ejection state of the flame is fundamentally improved, and the flame ejected during the singeing process is stable and controllable, ensuring the quality of singeing.

[0035] like Figure 6 As shown, in order to achieve further precise control and adjustment of the combustion flame and achieve refined singeing, an adjustment device 30 for adjusting the singeing distance between the second nozzle 19 and the grey cloth 1 is provided on the side wall of the lower shell 13 of the singeing burner 11. The adjustment device 30 includes a support seat 32 having a slide groove 31, and a sliding seat 33 slidably connected to the slide groove 31, one end of the sliding seat 33 is fixed to the side wall of the lower shell 13, and the other end is provided with a threaded hole, and a screw rod 34 spirally connected to the threaded hole for driving the singeing burner 11 to telescopically move is provided on the support seat 32, and a rotating handle 35 is provided on the screw rod 34.

[0036] Since the flame temperature and singeing speed are often difficult to control in the prior art, the utility model reduces the phenomenon of cloth burning caused by inaccurate adjustment of the burner distance by adjusting the adjustment device 30 and the flame spraying state of the singeing burner 11, solves the problem of damage to the grey cloth caused by too low temperature (under-burning), the fluff is not easy to burn cleanly, and the temperature is too high or the speed is slow (over-burning) in the traditional singeing process, and realizes the precise adjustment of the singeing distance, reducing the difficulty of controlling the temperature and speed in the singeing process. Of course, in order to realize automatic control, the manual rotating handle 35 in the utility model can be replaced by a servo motor and controller signal drive mode, and the distance between the flame sprayed from the singeing burner 11 and the grey cloth 1 is monitored in real time, and the rotation of the screw rod 34 is controlled by the servo motor signal to realize the purpose of automatic adjustment.

[0037] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the protection scope of the present invention.
