Description

Technical Field

[0001] The utility model relates to the technical field of dyeing machines, in particular to a water-saving low-bath-ratio overflow dyeing machine. Background Technique

[0002] Low-bath-ratio overflow dyeing machines are mainly used for the pretreatment and dyeing of various knitted greige fabrics such as pure cotton, pure polyester, polyester-cotton, and spandex. They are particularly suitable for dyeing new synthetic fibers and superfine fibers with high added value. At the same time, they can also be used for processing such as fabric boiling, bleaching, pre-shrinking, and alkali deweighting.

[0003] During the dyeing process of the existing overflow dyeing machine, when the fabric is removed from the inside of the dyeing machine after dyeing, it is easy to carry excessive dyeing liquid. During the transfer process of the fabric, the dyeing liquid will drip into the working environment, causing environmental pollution. At the same time, a large amount of water will be carried out and spilled outside, resulting in waste of water resources and poor practicability. Therefore, to improve the water-saving performance of the low-bath-ratio overflow dyeing machine, we propose a water-saving low-bath-ratio overflow dyeing machine. Content of the Utility Model

When the fabric is pulled, the water outside the fabric is squeezed out through the cooperation of the plurality of outer water squeezing rollers and the inner water squeezing roller. The design of this water squeezing structure is ingenious. The water is squeezed through the cooperation of a plurality of annularly distributed outer water squeezing rollers and a group of inner water squeezing rollers. It has a small volume and can squeeze water multiple times, with good water squeezing effect. The squeezed water will be collected by the liquid collecting box, thereby saving water resources and solving the problems in the background.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-6 , the present utility model provides a technical solution: a water-saving low liquor ratio overflow dyeing machine, which includes a base 1, a dyeing machine body 2 is installed on the base 1, two groups of brackets 14 are fixedly connected to the dyeing machine body 2, a liquid collecting box 11 is fixedly connected to the bottom of the bracket 14, a cloth passing port 13 is opened on the liquid collecting box 11, a cloth guiding roller 17 is rotatably installed on the bracket 14, a circular frame 15 is fixedly connected to the bracket 14, a fixed disk 16 is fixedly connected to the inner side of the circular frame 15, an inner water squeezing roller 18 is rotatably installed between the middles of the two groups of fixed disks 16, a plurality of annularly distributed sliding openings are opened on the fixed disk 16, a lead screw 24 is rotatably installed on the sliding opening, an adjusting block 23 is threadedly connected to the lead screw 24, an outer water squeezing roller 19 is rotatably installed between the corresponding two groups of adjusting blocks 23, and a transmission component is connected between the lead screws 24 on the two groups of fixed disks 16.

[0029] During use, after passing the fabric through the cloth passing port 13, the fabric is passed through the gap between the inner water squeezing roller 18 and the outer water squeezing roller 1. Then, the transmission component drives a plurality of lead screws 24 to rotate synchronously. When the lead screws 24 rotate, they will drive a plurality of outer water squeezing rollers 19 to move inwards synchronously. At this time, the plurality of outer water squeezing rollers 19 cooperate with the inner water squeezing roller 18 to clamp the fabric. When the fabric is pulled, the water on the outside of the fabric is squeezed out through the cooperation of the plurality of outer water squeezing rollers 19 and the inner water squeezing roller 18. The design of this water squeezing structure is ingenious. The water is squeezed through the cooperation of a plurality of annularly distributed outer water squeezing rollers 19 and a group of inner water squeezing rollers 18. It has a small volume and can squeeze water multiple times, with good water squeezing effect. The squeezed water will be collected by the liquid collecting box 11, thereby saving water resources.

[0030] The transmission component includes a motor 10, the motor 10 is fixedly installed on the bracket 14, a groove is opened in the middle of the fixed disk 16, one end of the lead screw 24 extends into the inside of the groove, and a driven bevel gear 22 is fixedly connected to the end of the lead screw 24. A driving bevel gear 21 is rotatably installed on the bracket 14 through a connecting shaft. The driving bevel gear 21 meshes with the driven bevel gear 22. The output end of the motor 10 is fixedly connected to the connecting shaft on the right driving bevel gear 21. An installation pipe 9 is fixedly connected above the fixed disk 16. A transmission rod 8 is rotatably installed inside the installation pipe 9. A first bevel gear 25 is fixedly connected to the end of the transmission rod 8. A second bevel gear 26 is fixedly connected to the top of one of the lead screws 24. The second bevel gear 26 meshes with the first bevel gear 25.

[0031] Since the second bevel gear 26 meshes with the first bevel gear 25, when the motor 10 operates, it will drive the two groups of driving bevel gears 21 to move simultaneously through the action of the transmission rod 8. And because the driving bevel gear 21 meshes with the driven bevel gear 22, when the motor 10 operates, a number of lead screws 24 on the two fixed disks 16 will rotate simultaneously, realizing the gap adjustment between the external water squeezing roller 19 and the internal extrusion roller 18 to adapt to the water squeezing of fabrics with different thicknesses.

[0032] The adjusting block 23 is slidably connected to the inner wall of the corresponding sliding opening on the fixed disk 16, which can make the external water squeezing roller 19 move stably.

[0033] A liquid return pipe 6 is fixedly connected between the liquid collecting tank 11 and the dyeing machine body 2, facilitating the backflow of the extruded water liquid into the dyeing machine body 2.

[0034] Two drying guide cylinders 7 are rotatably installed on the bracket 14. Rotating joints 20 are rotatably installed at both ends of the drying guide cylinder 7. The rotating joints 20 are fixedly embedded in the bracket 14. A heating box 3 is fixedly installed on the base 1. The heating box 3 is fixedly connected to the left rear rotating joint 20 through an air supply pipe 4. The rotating joints 20 on the front and rear sides of the right part are fixedly connected through a pipe. The rotating joint 20 on the front side of the left part is fixedly connected to an air outlet pipe 5. An air inlet pipe 12 is fixedly connected to the heating box 3. A blower and a number of electric heating rods are installed inside the heating box 3. The air outlet end of the air outlet pipe 5 is fixedly connected to the air inlet pipe 12.

[0035] A blower and a number of electric heating rods are installed inside the heating box 3, thereby generating hot air. The hot air will be circulated and heated in the drying guide cylinder 7 and the heating box 3, and then the fabric can be heated and dried after being led out.

[0036] An air filter is installed inside the air inlet pipe 12, which can filter the external air.

[0037] Working principle: When in use, pass the fabric through the fabric passing port 13, and make the fabric pass through the gap between the inner water squeezing roller 18 and the outer water squeezing roller 1. Since the second bevel gear 26 meshes with the first bevel gear 25, when the motor 10 works, it will drive the two groups of driving bevel gears 21 to move simultaneously through the action of the transmission rod 8. And because the driving bevel gear 21 meshes with the driven bevel gear 22, when the motor 10 works, several lead screws 24 on the two fixed disks 16 will rotate simultaneously, realizing the adjustment of the gap between the outer water squeezing roller 19 and the inner water squeezing roller 18 to adapt to the water squeezing of fabrics with different thicknesses. When the lead screw 24 rotates, it will drive several outer water squeezing rollers 19 to move inwards synchronously. At this time, several outer water squeezing rollers 19 and the inner water squeezing roller 18 cooperate to clamp the fabric. When the fabric is being pulled, the water on the outside of the fabric is squeezed out through the cooperation of several outer water squeezing rollers 19 and the inner water squeezing roller 18. This water squeezing structure is ingeniously designed. By the cooperation of several annularly distributed outer water squeezing rollers 19 and a group of inner water squeezing rollers 18 for water squeezing, it has a small volume, can squeeze water multiple times, and has a good water squeezing effect. The squeezed water liquid will be collected and recycled by the liquid collecting box 11, thereby saving water resources;

[0038] A blower and several electric heating rods are installed inside the heating box 3, thereby generating hot air. The hot air will circulate and heat in the drying guiding cylinder 7 and the heating box 3, so that the fabric can be heated and dried after being led out.
