Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to a widening device for flat-width dyeing. Background Technology

[0002] Dyeing and finishing, also known as printing and finishing, is a processing method that encompasses pretreatment, dyeing, printing, finishing, washing, and more. Plain-width fabrics undergo tension adjustment via a feeding device, allowing them to move smoothly into the dyeing machine under the traction of rollers. However, during dyeing and finishing, plain-width fabrics are prone to wrinkling due to uneven weft tension, resulting in unsatisfactory patterns. Therefore, appropriate widening devices are needed at the flat-width feeding points in pressing, drying, printing, and other stages to achieve wrinkle prevention and removal.

[0003] Width-expanding devices for flat-width dyeing typically include one or more widening rollers. These rollers are used to increase the width of the fabric to accommodate larger dye liquor volumes and circulation systems during the dyeing process. In addition, the widening device may include auxiliary equipment such as guide rollers, tension control devices, and temperature control devices to ensure that the fabric maintains a stable position and tension during the widening process and to ensure that the temperature and concentration of the dye liquor are uniformly transferred to the fabric surface.

[0004] A spreading device typically includes one or more spreading rollers, which can be made of materials of varying hardness, such as hard alloys or ceramics, to provide sufficient rigidity and abrasion resistance. Additionally, the spreading device includes guide rollers that guide the fabric through the spreading rollers and maintain its stable position during the spreading process. Tension control devices are used to control the tension of the fabric during spreading to ensure that it is not overstretched or twisted. Temperature control devices are used to control the temperature and concentration of the dye liquor to ensure that the fabric absorbs the dye uniformly.

[0005] In summary, the widening device used for flat-width dyeing is one of the most important pieces of equipment in the dyeing process. It can widen the fabric and ensure that the fabric can maintain a stable position and tension during the dyeing process, while ensuring that the temperature and concentration of the dye liquor can be evenly transferred to the fabric surface.

[0006] A fabric widening structure for a flat-width fabric dyeing machine (publication number CN211620879U) includes a feeding guide structure, an edge suction structure, a guide wheel structure, and a widening structure. The edge suction structure is located below the feeding guide structure, the guide wheel structure is located below the edge suction structure, and the widening structure is located on the side of the guide wheel structure away from the feeding guide structure. The widening structure includes a fabric tensioning structure and a widening roller structure, which are arranged side-by-side. The flat-width fabric to be dyed enters the dyeing machine along the feeding guide structure. First, the edge suction structure applies weft tension to the fabric and automatically guides it to its normal position. Then, the widening structure expands the fabric to prevent and remove wrinkles. All these structures work together to complete the fabric widening process.

[0007] However, in actual use, a spiral structure is still used to expand the width of the flat fabric, which means that the flat fabric is still subject to lateral friction, making the fabric surface prone to scratches and reducing the overall quality of the flat fabric. Summary of the Invention

[0008] The purpose of this invention is to provide a widening device for flat-width dyeing to solve the problems mentioned in the background art.

[0019] The present invention has at least the following beneficial effects: (1) This solution sets up an expansion mechanism. When expanding the width of the flat fabric, the movable frame slides upward inside the mounting slot, causing the movable frame to drive the mounting frame and the expansion component at the top of the mounting frame to move upward together. During the movement of the expansion component, the slider will move to one side under the pull of the connecting rope. When the expansion component moves to the top and contacts the flat fabric, the third spring inside the slider movable slot will push the slider back. At this time, the expansion component will move to one side under the pull of the connecting rope. During the movement, the bottom of the expansion component will contact the top of the inclined plate. Under the descent of the movable frame and the pull of the slider, the expansion component will slide on the top of the inclined plate. During the movement, the expansion component can expand the width of the flat fabric and avoid scratches on the flat fabric, thus ensuring the product quality of the flat fabric.

[0020] (2) By setting up an expansion plate and a pressure plate, when the flat fabric comes into contact with the expansion plate, the center of the flat fabric will be supported, causing the flat fabric to extend to both sides. By setting up the first spring and the connecting column, the pressure plate can be pressed down, so that the flat fabric fits the expansion plate more closely, thereby making the expansion effect of the expansion plate better.

[0021] (3) This scheme can adjust the operating frequency of the electric push rod by setting a control device, thereby adjusting the frequency of the expansion component.

[0022] (4) By setting the first feed roller and the second feed roller, the flat fabric can enter the first fixed frame through the first feed roller and the second feed roller. By setting the first feed roller and the second feed roller, the flat fabric will not be misaligned after entering the first fixed frame. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-11 The present invention provides a widening device for flat-width dyeing, comprising: The fixing frame includes a first fixing frame 1, a second fixing frame 2 and a third fixing frame 3; The feeding mechanism is installed inside the first fixed frame 1. The feeding mechanism guides the flat fabric 4 through the feeding roller and the guide roller. The guide roller 201 is installed inside the second fixed frame 2 to guide the flat fabric 4. The widening mechanism is installed inside the third fixed frame 3. The widening mechanism performs initial widening of the flat fabric 4 through the widening plate 303, and then widens the flat fabric 4 through the widening component 3043 inside the mounting plate 302.

[0027] In some embodiments, see Figure 4 , Figure 5 , Figure 7The expansion mechanism includes a slider 3024, a connecting rope 3026, a movable frame 304, and a mounting frame 3042. The mounting plate 302 is fixedly installed inside the third fixed frame 3. The mounting plate 302 has several mounting grooves 3021 arranged in a V-shape within it. The movable frame 304 is slidably connected to the mounting grooves 3021. The mounting frame 3042 is fixedly installed on one side of the movable frame 304.

The reciprocating slider 30432 is slidably connected to the side wall of the guide rail 30422 through the guide hole 30433. The reciprocating slider 30432 is also slidably connected to the reciprocating groove 30421 inside the guide rail 30422. The expander 3043 is slidably connected to the top of the mounting bracket 3042 through the reciprocating slider 30432. A fourth spring 30423 is fixedly mounted inside the reciprocating groove 30421. The mounting plate 302 has a slider movement groove 3023 inside. The slider 3024 is slidably connected inside the slider movable groove 3023. A third spring 3025 is fixedly installed at one end of the slider 3024. The slider 3024 is connected to the expansion member 3043 through the connecting pull rope 3026. An inclined plate 306 is fixedly installed on one side of the inner wall of the mounting groove 3021. When the flat fabric 4 is expanded, the movable frame 304 slides upward inside the mounting groove 3021, causing the movable frame 304 to drive the mounting frame 3042 and the expansion member 3043 at the top of the mounting frame 3042 to move upward together. During the movement of the expansion member 3043, the slider 3024 will move to one side under the pull of the connecting pull rope 3026. When the expansion member 3043 moves to the top and is connected to the flat fabric... After the object 4 comes into contact, the third spring 3025 inside the slider movable groove 3023 will push the slider 3024 back. At this time, the expansion member 3043 will move to one side under the pull of the connecting rope 3026. During the movement, the bottom of the expansion member 3043 will contact the top of the inclined plate 306. Under the descent of the movable frame 304 and the pull of the slider 3024, the expansion member 3043 will slide on the top of the inclined plate 306. During the movement, the expansion member 3043 can expand the width of the flat fabric 4 and avoid scratches on the flat fabric 4, thus ensuring the product quality of the flat fabric 4. When the expansion member 3043 is separated from the inclined plate 306, it will return to its original position under the push of the fourth spring 30423.

[0028] In some embodiments, see Figure 7One end of the fourth spring 30423 is fixedly installed on one side of the reciprocating movable slider 30432, and the other end of the fourth spring 30423 is fixedly installed on the inner wall of the reciprocating movable groove 30421. The fourth spring 30423 is located on the side wall of the guide rail 30422. By setting the fourth spring 30423, the reciprocating movable slider 30432 can be pushed to one side, so that the reciprocating movable slider 30432 will be pushed to one end of the guide rail 30422.

[0029] In some embodiments, see Figure 5 A connecting frame 30434 is fixedly installed at the bottom of the expansion plate 303. One end of the connecting rope 3026 is fixedly installed on one side of the slider 3024, and the other end of the connecting rope 3026 is fixedly installed inside the connecting frame 30434. By setting the connecting frame 30434, one end of the connecting rope 3026 can be installed inside the connecting frame 30434, so that the connecting rope 3026 can be connected to the expansion plate 303 through the connecting frame 30434. By setting the connecting rope 3026, the expansion plate 303 can be connected to the slider 3024. The sliding of the slider 3024 can pull the expansion plate 303 to move, or the movement of the expansion plate 303 can pull the slider 3024 to move.

[0030] In some embodiments, see Figure 7 , Figure 8 A support block 3044 is fixedly installed at the bottom of the expansion member 3043. The support block 3044 is located on one side of the connecting frame 30434. The support block 3044 matches the inclined plate 306. By setting the support block 3044, the expansion member 3043 can slide more smoothly on the top of the inclined plate 306, and avoid the expansion member 3043 from getting stuck when sliding on the top of the inclined plate 306.

[0031] In some embodiments, see Figure 5 , Figure 6 , Figure 7The mounting groove 3021 has a mounting cavity 305 at its bottom, which is connected to the mounting groove 3021. An electric push rod 3051 is fixedly installed inside the mounting cavity 305, with its output end located at the bottom of the movable frame 304. A guide groove 3022 is provided on one side of the mounting groove 3021, and a guide fixing rod 30221 is fixedly installed inside the guide groove 3022. A guide member 3041 is fixedly installed on one side of the movable frame 304, and a through groove 30411 is provided inside the guide member 3041.

The second spring 30222 is located on the side wall of the guide fixing rod 30221. By setting an electric push rod 3051, the extension of the electric push rod 3051 can push the movable frame 304 to move upward inside the mounting groove 3021. By setting the guide fixing rod 30221 and the guide 3041, the movement direction and movement range of the movable frame 304 can be restricted. By setting the second spring 30222, when the electric push rod 3051 is retracted, the second spring 30222 can push the guide 3041 and the movable frame 304 to descend to their original positions.

[0032] In some embodiments, see Figure 2 , Figure 3 , Figure 10 An expansion plate 303 is fixedly installed on the top of a mounting plate 302. A matching groove 3031 is provided inside the expansion plate 303, and several matching grooves 3031 are provided, each corresponding to a mounting groove 3021. A pressure plate mounting bracket 301 is fixedly installed inside the third fixing bracket 3. A first spring member 30112 is fixedly installed inside the pressure plate mounting bracket 301.

The pressure plate 3011 matches the expansion plate 303. The expansion plate 303 is an arc-shaped plate. When the flat fabric 4 comes into contact with the expansion plate 303, the center of the flat fabric 4 will be supported, causing the flat fabric 4 to extend to both sides. By setting the first spring 30112 and the connecting column 30111, the pressure plate 3011 can be pressed down, so that the flat fabric 4 fits the expansion plate 303 more closely, thereby making the expansion effect of the expansion plate 303 better. By opening the matching groove 3031 inside the expansion plate 303, the expansion component 3043 inside the mounting groove 3021 can extend to the top of the expansion plate 303 through the matching groove 3031.

[0033] In some embodiments, see Figure 1 , Figure 2A control device 5 is fixedly installed on one side of the third fixed frame 3.

The control panel 503 can be used to control the control module. The display module 502 can be used to observe the control status so as to adjust the operating frequency of the electric push rod 3051.

[0034] For further details, please refer to the following: Figure 11 The feeding mechanism includes a transmission device 101 and a drive motor 1011. The transmission device 101 is fixedly installed on one side of the first fixed frame 1, and the drive motor 1011 is fixedly installed on the connecting end of the transmission device 101. The guide roller is fixedly installed on the output end of the transmission device 101. The guide roller includes a first guide roller 1012 and a second guide roller 1013. The feeding roller is rotatably connected inside the first fixed frame 1 and includes a first feeding roller 102 and a second feeding roller 103. The first feeding roller 102 is located on top of the second feeding roller 103. By setting the first feeding roller 102 and the second feeding roller 103, the flat fabric 4 can be fed through the first feeding roller 102 and the second feeding roller 103. The fabric 4 is fed into the first fixed frame 1. The first feed roller 102 and the second feed roller 103 are set to ensure that the fabric 4 will not be misaligned after entering the first fixed frame 1. The transmission device 101 consists of two transmission gears, a transmission belt and a housing. The transmission belt drives the two transmission gears to rotate. The drive motor 1011 is installed on one side of the housing. One of the transmission gears is fixedly installed at the output end of the drive motor 1011. The operation of the drive motor 1011 can drive the transmission gear to rotate, thereby causing the two guide rollers to rotate simultaneously, so as to guide the fabric 4 inside the first fixed frame 1 and move the fabric 4 into the second fixed frame 2.

[0035] Furthermore, the guide roller 201 is rotatably connected inside the second fixed frame 2, which is located between the third fixed frame 3 and the first fixed frame 1. By setting the second fixed frame 2 between the first fixed frame 1 and the third fixed frame 3, the guide roller 201 inside the second fixed frame 2 can guide the flat fabric 4, allowing the flat fabric 4 to enter the widening mechanism for widening and avoiding damage to the flat fabric 4.

[0036] The working process and principle of this invention: In use, a flat fabric 4 is placed inside the first fixed frame 1. The first feed roller 102 and the second feed roller 103 ensure that the flat fabric 4 enters the first fixed frame 1 without misalignment. The drive motor 1011 rotates the transmission gear, causing the two guide rollers to rotate simultaneously, thus guiding the flat fabric 4 inside the first fixed frame 1. The flat fabric 4 is then moved into the second fixed frame 2, where the guide roller 201 further guides the flat fabric 4, ensuring it remains flat and evenly distributed. The fabric 4 can be easily inserted into the widening mechanism inside the third fixed frame 3. When the fabric 4 contacts the widening plate 303, the center of the fabric 4 is supported, causing the fabric 4 to extend to both sides. By setting the first spring 30112 and the connecting column 30111, the pressure plate 3011 can be pressed downward, making the fabric 4 fit more closely to the widening plate 303, thus improving the widening effect of the widening plate 303. Then, by extending the electric push rod 3051, the movable frame 304 can be pushed upward inside the mounting slot 3021, causing the movable frame 304 to move the mounting plate 3021 upward. The mounting bracket 3042 and the expansion member 3043 at the top of the mounting bracket 3042 move upward together. During the movement of the expansion member 3043, the slider 3024 will move to one side under the pull of the connecting rope 3026. When the expansion member 3043 moves to the top and contacts the flat fabric 4, the electric push rod 3051 quickly retracts. After the electric push rod 3051 retracts, the second spring member 30222 can push the movable frame 304 down. During the descent, the third spring member 3025 inside the slider movable groove 3023 will push the slider 3024 back. At this time, the expansion member... 3043 will move to one side under the pull of the connecting rope 3026. During the movement, the bottom of the expansion member 3043 will contact the top of the inclined plate 306. Under the descent of the movable frame 304 and the pull of the slider 3024, the expansion member 3043 will slide on the top of the inclined plate 306. During the movement, the expansion member 3043 can expand the width of the flat fabric 4. When the expansion member 3043 is separated from the inclined plate 306, it will return to its original position under the push of the fourth spring member 30423. Then it will be pushed up by the electric push rod 3051. This process is repeated to expand the width of the flat fabric 4.
