A raw material dyeing device for sweater production

Abstract

This utility model relates to the field of sweater production technology, and in particular to a dyeing device for sweater production raw materials, including a dye box and guide rollers. The fabric is arranged in a U-shape inside the dye box by a pair of guide rollers that are rotated. Inside the right end of the dye box, a pair of liftable sleeves located on the left side above the fabric are slidably arranged by a guide device. When the dye water level changes during use, the float rises and falls accordingly to keep the height of the air outlet pipe relative to the liquid surface constant. The blowing air improves the cleanliness and cleaning stability, while eliminating the need for an additional drive device, saving energy and protecting the environment. It can also be adjusted in real time. The height of the air outlet pipe relative to the liquid surface can be adjusted by increasing or decreasing the float density by unscrewing the sealing plug.

Description

Technical Field

[0001] This utility model relates to the field of sweater production technology, and in particular to a raw material dyeing device for sweater production. Background Technology

[0002] Sweaters, machine- or hand-knitted woolen garments, originated from the use of leaves and animal hides for clothing in primitive life. During fishing and herding, humans learned to use weaving techniques. With the evolution of civilization and technological inventions, humans not only fully utilize various natural fibers from animals and plants to weave necessities for daily life, but also develop various chemical and mineral fibers, making human life more comfortable and convenient. An existing application (CN202020366955.X) describes a dyeing device for sweater production, including a dye box and fabric. The dye box has guide shafts fixedly connected to it in a left-right distribution… blowing the surface dye liquid into the dye box, thus avoiding pollution of the working environment and preventing waste of dye liquid, ensuring its full utilization. However, this device requires additional adjustment of the blowing pipe height via an electric telescopic rod when the dye level changes. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where the height of the blow tube needs to be adjusted via an electric telescopic rod when the dye level changes, and to propose a raw material dyeing device for sweater production.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5 A dyeing device for raw materials used in sweater production includes a dye box 1 and guide rollers. A pair of guide rollers 2, which are rotatably arranged, are used to arrange fabric 3 in a U-shape inside the dye box 1. A pair of liftable sleeves 6, located on the left side above the fabric 3, are slidably arranged inside the right end of the dye box 1 through a guide device. A top plate 14 and a bottom plate 13 are respectively fixed at both ends of the pair of lift sleeves 6. An inverted U-shaped tube 15 and a float 8 are respectively fixed at the bottom of the top plate 14 and the bottom plate 13. The U-shaped tube 15 is connected to an air inlet device. A pair of air outlet pipes 16, which are arranged vertically and rotatably connected to the U-shaped tube 15, are rotatably arranged inside the U-shaped tube 15. Several air outlet holes 19 are opened on the outer wall of the air outlet pipes 16. An adjustment and positioning device is provided at the left end of the air outlet pipes 16. A filter screen 4 is connected to the left end of the float 8 through a filter screen connection structure.

[0021] The air intake device includes a fan 7 and an air intake pipe 5. The top of the U-shaped pipe 15 has a through hole, and the air intake pipe 5 is fixed inside the through hole. The right end of the dye box 1 is fixed with a support plate, and the top of the support plate is fixedly installed with the fan 7. The air outlet of the fan 7 is connected to the air intake pipe 5 through a flexible hose.

[0022] The bottom of the float 8 has a threaded hole, and a sealing plug 22 is threaded into the threaded hole.

[0023] The adjustment and positioning device includes a knob 18, a worm gear 20, and a worm 21. The worm gear 20 is fixedly installed at the left end of the air outlet pipe 16. The worm 21 is rotatably installed inside the U-shaped pipe 15, and the front and rear ends of the worm 21 pass through and rotatably connect to the U-shaped pipe 15 respectively. The worm 21 meshes with the worm gear 20, and the knob 18 is fixedly installed at the front end of the worm 21.

[0024] The guiding device includes guide rods 9 and top rings 17. A pair of guide rods 9 are fixed at the bottom of the dye box 1, and lifting sleeves 6 are respectively fitted on the outer walls of the pair of guide rods 9. A top ring 17 is fixed at the top of the guide rods 9.

[0025] The filter screen connection structure includes a connecting rod 10 and a guide groove. The guide groove is provided on the front and rear inner walls of the dye box 1, and the filter screen 4 is slidably arranged in the guide groove. The left end of the float 8 is fixedly provided with the connecting rod 10, and the left end of the connecting rod 10 is fixedly connected to the filter screen 4.

[0027] Working principle: The buoyancy of the float 8 lifts the lifting sleeve 6, U-shaped tube 15, etc., so that the two air outlets 16 are above the dye liquid surface. Rotating the knob 18 causes the two air outlets 16 to rotate through the worm gear 20 and worm 21, so that the air outlets 19 of the two air outlets 16 are tilted to the lower left and aligned with the dye liquid surface, and tilted to the lower right and aligned with the fabric 3, respectively. The air blown out through the air outlets 19 removes impurities on the dye surface by blowing to the left, while the air blown out through the right pre-dries the fabric 3 and blows off the dye. When the dye level changes, the float 8 rises and falls accordingly to keep the height of the air outlets 16 relative to the liquid surface constant. The height of the air outlets 16 relative to the liquid surface can be adjusted by increasing or decreasing the density of the float 8 by unscrewing the sealing plug 22.

[0028] When the dye level changes during use, the float 8 rises and falls accordingly to keep the height of the air outlet pipe 16 relative to the liquid surface constant. The air blowing improves the cleanliness and cleaning stability, while eliminating the need for an additional drive device, saving energy and protecting the environment. It can also be adjusted in real time. The height of the air outlet pipe 16 relative to the liquid surface can be adjusted by increasing or decreasing the density of the float 8 by unscrewing the sealing plug 22.
