Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester fabric dyeing technology, specifically to a water-saving device for polyester fabric dyeing processing. Background Technology
[0002] Polyester fiber, commonly known as "polyester," is a synthetic fiber made from organic diacids and diols through chemical polycondensation. It belongs to the category of polymer compounds. Its invention can be traced back to the 1930s, and it is now one of the most important synthetic fibers. Polyester fiber has many advantages. First, it has excellent wrinkle resistance and shape retention, making clothing less prone to wrinkling during wear and able to maintain its original shape. Second, polyester fiber has high strength and elastic recovery, making woven fabrics strong and durable while quickly returning to their original shape. Furthermore, polyester fiber is also abrasion-resistant and lint-free, making fabrics look neater. In general, polyester fiber is a very practical synthetic fiber, widely used in textile and clothing manufacturing, bringing much convenience and comfort to our daily lives.
[0003] In current polyester fabric dyeing processes, dye needs to be adsorbed into the polyester fabric. The dye liquid adsorbed by the polyester fabric in the dyeing vat is in a saturated state. When the polyester fabric is taken out of the dyeing vat, the dye liquid will fall from the surface of the polyester fabric onto the ground, resulting in waste of dye and water resources. To address this, we propose a water-saving device for polyester fabric dyeing processing. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a water-saving device for dyeing polyester fabric, which can squeeze out excess dye liquid from polyester fabric, avoid waste of dye and water resources, and effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-saving device for polyester fabric dyeing and processing, comprising a mounting box and a moving component;
[0006] Mounting box: The upper left side of the inside is rotatably connected to two corresponding limiting shafts, and the lower side of the inside of the mounting box is rotatably connected to a guide shaft. A polyester cloth is provided between the two limiting shafts, and the polyester cloth is located at the lower end of the guide shaft.
[0007] The moving component includes a fixed frame, racks, hexagonal prisms, and a first spring. Two corresponding fixed frames are fixed to the right side inside the mounting box. Two parallel racks are arranged on the left side inside the fixed frames. A hexagonal hole is formed in the middle of each rack, and a hexagonal prism is slidably connected inside the hexagonal hole. Both hexagonal prisms are fixed inside the fixed frames. A first spring is fitted onto the surface of each hexagonal prism. One end of the first spring is fixed to the side of the rack, and the other end is fixed to the side inside the fixed frame. A toggle assembly is installed between the two fixed frames. The toggle assembly is connected to four racks. A rotating assembly is installed on the front side of the toggle assembly. A squeezing assembly is installed between the four racks.

During the rotation of the one-third sector gear, when it contacts the gear, it will drive the gear to rotate. The rotation of the gear will drive the four racks to move. When the one-third sector gear moves away from the gear, it will drive the four racks to reset under the action of the four first springs. Continuously controlling the rotation of the one-third sector gear will make the four racks move up and down reciprocatingly, thereby driving the two extrusion strips to move up and down reciprocatingly.
[0010] Furthermore, the extrusion assembly includes a T-block, a connecting strip, a slide rod, a connecting plate, a second spring, and an extrusion strip. Two corresponding T-blocks are arranged on the upper and lower sides of the rotating shaft. The front and rear sides of the two T-blocks are respectively connected to the sides of four racks. A connecting strip is fixed to the upper side of the lower T-block. Two extrusion strips are provided. The polyester fabric is located between the two extrusion strips. Two corresponding slide rods are fixed to the upper side of the upper extrusion strip. Two corresponding sliding holes are opened on the upper side of the upper T-block. The slide rods are slidably connected to the inside of the corresponding sliding holes. A connecting plate is fixed to the upper end of the slide rod. A second spring is sleeved on the circumference of the slide rod. The upper end of the second spring is fixed to the lower end of the connecting plate, and the lower end of the second spring is fixed to the upper side of the upper T-block. By setting up the extrusion assembly, excess dye and water in the polyester fabric are squeezed out.
[0011] Furthermore, a drain pipe is fixed inside the drain port on the left side of the installation box, and a sealing cap is threaded to the left end of the drain pipe. The drain pipe facilitates the expulsion of excess water and dye from inside the installation box.
[0012] Furthermore, a support net is fixed at the upper end between the two fixed frames, the polyester fabric is located above the support net, and an inclined guide block is fixed on the lower side inside the mounting box. The polyester fabric is supported by the support net.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This water-saving device for polyester fabric dyeing and processing has the following advantages:
[0014] The reciprocating motion of the upper and lower extrusion strips efficiently squeezes out excess dye liquid saturated and adsorbed in the polyester fabric, significantly reducing unnecessary loss of dye and water resources during the dyeing process. This design not only reduces wastewater discharge during production but also improves dye utilization, thereby alleviating the environmental burden. Simultaneously, the extruded liquid is collected by the inclined guide block and recycled through the drain pipe, achieving resource recycling. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-3 This embodiment provides a technical solution: a water-saving device for dyeing polyester fabric, including a mounting box 1 and a moving component 5;
[0021] Mounting box 1: The upper left side of the interior is rotatably connected to two corresponding limiting shafts 2, and the lower side of the interior of mounting box 1 is rotatably connected to a guide shaft 3. A polyester cloth 4 is set between the two limiting shafts 2, and the polyester cloth 4 is located at the lower end of the guide shaft 3.
[0022] The movable component 5 includes a fixed frame 51, racks 52, hexagonal prisms 53, and a first spring 54. Two corresponding fixed frames 51 are fixed to the right side inside the mounting box 1. Two parallel racks 52 are arranged on the left side inside the fixed frame 51. A hexagonal hole is formed in the middle of each rack 52, and a hexagonal prism 53 is slidably connected inside the hexagonal hole. Both hexagonal prisms 53 are fixed inside the fixed frame 51. A first spring 54 is fitted onto the surface of each hexagonal prism 53. One end of the first spring 54 is fixed to the side of the rack 52, and the other end is fixed to the side inside the fixed frame 51. A toggle assembly 6 is installed between the two fixed frames 51. The toggle assembly 6 is connected to the four racks 52, and a rotating assembly is installed on the front side of the toggle assembly 6. Component 7 includes a pressing assembly 8 installed between four racks 52. The actuating assembly 6 includes a mounting plate 61, a rotating shaft 62, a gear ring 63, and a gear 64. The mounting plate 61 is fixed to the side of the fixing frame 51. A rotating hole is opened in the middle of the mounting plate 61. The rotating shaft 62 is rotatably connected inside the two rotating holes. The gear ring 63 is provided inside the fixing frame 51. The gear ring 63 meshes with two racks 52 located inside the fixing frame 51. Both gear rings 63 are fixed on the circumferential surface of the rotating shaft 62. The gear 64 is fixed to the front end of the rotating shaft 62. The rotating assembly 7 includes a motor 71 and a one-third sector gear 72. The motor 71 is installed on the front side of the mounting plate 61. The one-third sector gear 72 is fixed on the output shaft of the motor 71. One sector gear 72 meshes with gear 64. The input end of motor 71 is electrically connected to the output end of an external control switch. The extrusion assembly 8 includes a T-block 81, a connecting strip 82, a slide rod 83, a connecting plate 84, a second spring 85, and an extrusion strip 86. Two corresponding T-blocks 81 are provided on the upper and lower sides of the rotating shaft 62. The front and rear sides of the two T-blocks 81 are respectively connected to the sides of four racks 52. The connecting strip 82 is fixed on the upper side of the lower T-block 81. Two extrusion strips 86 are provided. Polyester fabric 4 is located between the two extrusion strips 86. Two corresponding slide rods 83 are fixed on the upper side of the upper extrusion strip 86. Two corresponding sliding holes are opened on the upper side of the upper T-block 81. The slide rods 83 are slidably connected to the corresponding sliding holes. Inside, a connecting plate 84 is fixed to the upper end of the slide rod 83, and a second spring 85 is sleeved on the circumference of the slide rod 83. The upper end of the second spring 85 is fixed to the lower end of the connecting plate 84, and the lower end of the second spring 85 is fixed to the upper side of the T-shaped block 81. Excess dye and water in the polyester fabric 4 are squeezed out by the extrusion component 8. The rotation component 7 enables the motor 71 to be started during use, causing the one-third sector gear 72 to rotate. During the rotation of the one-third sector gear 72, when it contacts the gear 64, it will drive the gear 64 to rotate. The rotation of the gear 64 will drive the four racks 52 to move. When the one-third sector gear 72 moves away from the gear 64, the four racks 52 will be reset under the action of the four first springs 54.Continuously controlling the rotation of one-third of the sector gear 72 causes the four upper and lower racks 52 to reciprocate up and down, thereby driving the two extrusion strips 86 to reciprocate up and down. By setting the actuating component 6 to move the four racks 52, and by setting the moving component 5 to move the two extrusion strips 86, excess dye and water on the polyester fabric 4 are squeezed out.
[0023] Among them: the drain port on the left side of the installation box 1 is fixed with a drain pipe 9, and the left end of the drain pipe 9 is threaded with a sealing cap 10. The drain pipe 9 makes it easy to squeeze out excess water and dye inside the installation box 1.
[0024] Among them: a support net 11 is fixed at the upper end between the two fixed frames 51, the polyester cloth 4 is located above the support net 11, and an inclined guide block 12 is fixed on the lower side inside the mounting box 1. The polyester cloth 4 is supported by the support net 11.
[0025] The working principle of the water-saving device for polyester fabric dyeing and processing provided by this utility model is as follows: During operation, the polyester fabric 4 passes through the two limiting shafts 2 and extends to the surface of the support net 11 below the guide shaft 3. The start motor 71 drives the one-third sector gear 72 to rotate. When the sector gear 72 meshes with the gear 64, it drives the rotating shaft 62 and the gear rings 63 at both ends to rotate. The gear rings 63 drive the four racks 52 in the fixed frame 51 to slide along the hexagonal prism 53. At this time, the first spring 54 is compressed. The linear movement of the racks 52 pushes the upper and lower T-blocks 81 to move towards each other. During the movement of the two T-blocks 81, the upper T-block 81 drives the extrusion strip 86 to press down through the slide rod 83. At the same time, the second spring 85 provides buffer pressure, while the lower T-block 81 is compressed by the slide rod 83. The connecting bar 82 pushes the lower extrusion bar 86 upward, and the two extrusion bars 86 form an intermittent extrusion motion, squeezing out the saturated dye liquid inside the polyester fabric 4. The extruded liquid is collected at the bottom of the mounting box 1 by the inclined guide block 12, and finally recovered through the drain pipe 9. When the sector gear 72 disengages from the gear 64, the first spring 54 pushes the rack 52 to reset, and the extrusion bars 86 separate. At this time, the polyester fabric 4 can continue to be conveyed, realizing periodic extrusion and dehydration. The entire process is precisely controlled by mechanical linkage to control the extrusion frequency and pressure, which avoids dye waste and ensures that the fabric is not damaged.
[0026] It is worth noting that the external control switch disclosed in the above embodiments is equipped with a button corresponding to the motor 71, and the motor 71 can be a 1LE0003 three-phase asynchronous motor.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
