Description

Technical Field

[0001] The utility model relates to the technical field of denim fabric production, in particular to a water scraping device for denim fabric dipping. Background Technique

[0002] Denim is a relatively thick and heavy yarn-dyed warp-faced twill cotton fabric. The warp yarns are dark in color, generally indigo blue, and the weft yarns are light in color, generally light gray or the original white yarn after scouring. Denim generally adopts a 3 / 1 weave, and there are also variations of twill, plain or crepe weave denim. The grey fabric is subjected to a shrinkage prevention finish, and the shrinkage rate is smaller than that of general fabrics. It has a tight texture, is thick, has bright colors, and clear weave patterns.

[0003] During the production process of denim, multiple dipping and rinsing operations are required. After the fabric is taken out of the dipping tank, the residual dyeing agent needs to be scraped off by extrusion to facilitate subsequent drying work. When the existing water scraping device is installed at the end of the denim, the operation of inserting the denim into a narrow gap is very inconvenient, and it is impossible to ensure that the denim is always effectively squeezed and scraped by the water scraping plate and the contact plate, resulting in unsatisfactory water scraping effect in some areas. Content of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides a water scraping device for denim fabric dipping.

[0005] The utility model is realized by the following technical solutions:

The lifting plate is fixedly arranged at the telescopic end of the oil cylinder, the moving rod is clamped inside the lifting plate, the first spring is sleeved outside the moving rod, the contact plate is fixedly arranged at the top of the moving rod, and the cloth pulling mechanism is arranged at both ends of the bottom of the contact plate.

[0007] In a preferred embodiment of the utility model, the cloth pulling mechanism includes a guiding track, a pulling rod, a second spring, a sliding block, a supporting seat, a pressing rod, a third spring and a clamping strip. The guiding track is fixedly arranged at both ends of the bottom of the contact plate, the pressing rod is clamped inside the guiding track, the second spring is sleeved outside the pulling rod, the sliding block is fixedly arranged at the end of the pulling rod, the supporting seat is fixedly arranged at the bottom of the sliding block, the pressing rod is clamped on the top of the supporting seat, the third spring is sleeved outside the pressing rod, and the clamping strip is fixedly arranged at the bottom of the pressing rod;

[0008] The fabric pulling mechanism is mainly used to fix both sides of the end of the denim fabric, and quickly pass the end of the fabric through between the scraping plate and the contact plate by pulling the pull rod, so as to facilitate the quick installation of the denim fabric.

[0009] In a preferred embodiment of the present invention, the third spring is located at the top of the support seat, the upper surface of the clamping strip fits with the inner side of the top of the support seat, and anti-slip grooves are provided on the upper surface of the clamping strip;

[0010] Press down the pressure lever to compress and contract the third spring, and the clamping strip moves downward, so as to form a space convenient for clamping the fabric between the clamping strip and the inner side of the top of the support seat.

[0011] In a preferred embodiment of the present invention, one end of the pull rod penetrates and extends to the outside of one end of the guiding track, and a handle is provided at its end;

[0012] The handle facilitates the quick operation of the pull rod. Pull the pull rod to control the movement of the sliding block, so as to control the movement of the end of the fabric. The second spring facilitates the automatic reset of the sliding block.

[0013] In a preferred embodiment of the present invention, a limiting piece is provided at the bottom of the moving rod, and the first spring is arranged between the lifting plate and the contact plate.

[0014] In a preferred embodiment of the present invention, the scraping plate has a V-shaped structure, the scraping plate is inclined, and one end of the scraping plate fits with the upper surface of the contact plate;

[0015] The bottom of the scraping plate fits with the contact plate to clamp the denim fabric, so that when the denim fabric is pulled, the liquid such as the dyeing agent contained therein can be squeezed out. The V-shaped and inclined scraping plate is mainly convenient for draining water.

[0016] The beneficial effects of the present invention are:

[0017] The water scraping device for dyeing denim fabric mainly quickly squeezes out the residual liquid in the fabric after dyeing, thereby reducing the subsequent drying difficulty and shortening the drying time.

Detailed implementation manners

[0024] The following elaborates on the preferred embodiments of the present utility model in conjunction with the attached drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined. The directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0025] As Figures 1-5 shown, a water scraping device for dyeing denim fabric includes a base 1, a fixed frame 2, a fixed rod 3, a scraper 4, an oil cylinder 5 and a height control mechanism 6. The fixed frame 2 is fixedly arranged on the top of the base 1, the fixed rod 3 is fixedly arranged inside the top of the fixed frame 2, the scraper 4 is fixedly arranged at the bottom of the fixed rod 3, the oil cylinder 5 is installed inside the base 1, and the height control mechanism 6 is installed at the telescopic end of the oil cylinder 5. The height control mechanism 6 includes a lifting plate 61, a moving rod 62, a first spring 63, a contact plate 64 and a cloth pulling mechanism 65. The lifting plate 61 is fixedly arranged at the telescopic end of the oil cylinder 5, the moving rod 62 is clamped inside the lifting plate 61, the first spring 63 is sleeved outside the moving rod 62, the contact plate 64 is fixedly arranged at the top of the moving rod 62, and the cloth pulling mechanism 65 is arranged at both ends of the bottom of the contact plate 64.

[0026] Specifically, the fabric pulling mechanism 65 includes a guiding track 651, a pull rod 652, a second spring 653, a sliding block 654, a support seat 655, a pressing rod 656, a third spring 657, and a clamping strip 658. The guiding track 651 is fixedly arranged at both ends of the bottom of the contact plate 64. The pressing rod 656 is clamped inside the guiding track 651. The second spring 653 is sleeved outside the pull rod 652. The sliding block 654 is fixedly arranged at the end of the pull rod 652. The support seat 655 is fixedly arranged at the bottom of the sliding block 654. The pressing rod 656 is clamped at the top of the support seat 655. The third spring 657 is sleeved outside the pressing rod 656. The clamping strip 658 is fixedly arranged at the bottom of the pressing rod 656. The third spring 657 is located at the top of the support seat 655. The upper surface of the clamping strip 658 is in contact with the inner side of the top of the support seat 655. The upper surface of the clamping strip 658 is provided with anti-slip grooves. One end of the pull rod 652 penetrates and extends outside one end of the guiding track 651, and a handle is arranged at its end. A limiting piece is arranged at the bottom of the moving rod 62. The first spring 63 is arranged between the lifting plate 61 and the contact plate 64. The scraping plate 4 is in a V-shaped structure and is inclined. One end of the scraping plate 4 is in contact with the upper surface of the contact plate 64.

[0027] In this embodiment, when it is necessary to squeeze and scrape water from the fabric, first, the oil cylinder 5 drives the height control mechanism 6 at its top to descend. When the oil cylinder 5 contracts, the bottom of the scraping plate 4 is separated from the upper surface of the contact plate 64, thus forming a fabric installation space. Subsequently, press the end of the pressing rod 656 downward, so that the third spring 657 is compressed and contracted, and the clamping strip 658 moves downward. Clamp both ends of one end of the fabric between the inner side of the top of the support seat 655 and the clamping strip 658. Subsequently, release the pressing rod 656. Under the action of the third spring 657, the clamping strip 658 clamps both ends of one end of the denim fabric. Then, pull the handle at the end of the pull rod 652 backward, so that the sliding block 654 moves backward, squeezing the second spring 653, thereby pulling the support seat 655 at the bottom of the sliding block 654 backward, enabling the end of the fabric to quickly pass through the narrow area between the scraping plate 4 and the contact plate 64, thus facilitating the fabric installation work.

[0028] Further, press the pressing rod 656 downward again to separate the clamping strip 658 from the fabric end. Under the action of the second spring 653, the sliding block 654 automatically resets. Subsequently, the oil cylinder 5 extends, driving the lifting plate 61 at its end to rise until the contact plate 64 at its top contacts the bottom of the scraping plate 4 and clamps the fabric. At this time, the moving rod 62 descends, and the first spring 63 is compressed and contracted. Under the reaction force of the first spring 63, it is ensured that the contact plate 64 and the scraping plate 4 squeeze and clean the liquid remaining in the fabric. Subsequently, under the pulling of the fabric winding device, the remaining water such as dyes in the fabric will be squeezed out and flow out along the inclined scraping plate 4, thereby reducing the water content in the fabric. The fixing frame 2 and the fixing rod 3 are mainly for facilitating the installation of the scraping plate 4. The bottom of the scraping plate 4 is in a V-shaped structure, and its bottom effectively contacts the fabric surface, which is conducive to squeezing out the water in the fabric.
