Description

Technical Field

[0001] This application relates to the field of textile equipment technology, and in particular to a yarn dyeing equipment. Background Technology

[0002] Yarn is a product made from various textile fibers processed to a certain fineness, used for weaving, rope making, thread making, knitting, and embroidery. Common yarns are divided into staple fiber yarns and continuous filament yarns. In order to obtain yarns of different colors during production and processing, it is often necessary to dye the yarns. There are various methods for dyeing yarns, such as skein dyeing, cone dyeing, warp beam dyeing, warp beam pad dyeing, and ball dyeing.

[0003] Chinese patent CN102409491B discloses a zero-emission waterless continuous dyeing system and dyeing method. Multiple sets of spray curtains are arranged vertically in the waterless chamber, and the liquid inlets of the multiple sets of spray curtains are connected to the liquid inlet pipe through solenoid valves. The signal control terminal of the solenoid valve is connected to the signal terminal of the PLC controller. The inlet of the liquid inlet pipe is connected to the outlet of the pressure pump. The inlet of the pressure pump is connected to the dye tank through a pipe. The spray curtains are equipped with upper and lower guide rollers respectively. The central shaft at the end of the lower guide roller is driven by a motor to rotate synchronously through a transmission mechanism. Whether the pressure pump and the motor work is controlled by the PLC controller.

[0004] This method uses spray nozzles in multiple spray curtains to spray atomized dye solution, which dyes the fabric. However, due to the large space of the entire waterless room, it is difficult to achieve uniform distribution of the atomized dye solution, which can easily lead to color differences in the dyed fabric and affect the dyeing quality. Utility Model Content

Each dyeing mechanism includes a feeding pipe, several atomizing nozzles connected to the feeding pipe, and a contact roller connected inside the box. Liquid inlet pipes are connected to both ends of the feeding pipe. The yarn abuts against the contact roller and passes over the contact roller. The feeding pipe is located above the contact roller and parallel to the contact roller. Several contact grooves are coaxially formed around the contact roller on the outer wall of the contact roller.

A collection pipe is connected to both ends of the collection hopper. The two collection pipes are respectively connected to the inlet pipes at both ends of the feeding pipe. A water pump is connected to one of the collection pipes to allow the dye in the collection hopper to enter the inlet pipe.

[0010] Preferably, the bottom plate of the liquid collecting hopper is inclined downward toward the side closer to the water pump.

[0011] Preferably, a mounting plate is fixed inside the box, a telescopic cylinder is fixed on the mounting plate, and the connecting rod of the telescopic cylinder is fixed on the feeding pipe.

[0018] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0019] This application discloses a yarn dyeing device.

[0020] Reference Figure 1 A yarn dyeing device includes a box 1 with openings at both ends. Several guide rollers 2 are rotatably connected inside the box 1. The guide rollers 2 are parallel to each other and arranged horizontally. A traction device is provided outside the box 1. The yarn moves forward by passing through the guide rollers 2 in sequence under the action of the traction device.

[0021] Reference Figure 1 and Figure 2 The box 1 is equipped with several sets of spray dyeing mechanisms. The spray dyeing mechanism includes a feeding pipe 3 parallel to the guide roller 2, several atomizing nozzles 4 connected to the feeding pipe 3, and abutting rollers 5 connected to the box 1. The abutting rollers 5 are parallel to the guide roller 2. During the movement, the yarn abuts against the abutting rollers 5 and passes over the abutting rollers 5. The line connecting the several atomizing nozzles 4 is on the same straight line and the several atomizing nozzles 4 are evenly distributed in the length direction of the feeding pipe 3.

[0022] Reference Figure 1 and Figure 2 The feeding pipe 3 is connected to the liquid inlet pipe 6 at both ends. The outer wall of the abutting roller 5 is coaxially provided with several abutting grooves 7 surrounding the abutting roller 5. The abutting grooves 7 correspond one-to-one with the atomizing nozzles 4, and the nozzles of the atomizing nozzles 4 are directly facing the abutting grooves 7. The yarn is divided into several parts and located in the corresponding abutting grooves 7. The bottom wall of the abutting groove 7 has an arc-shaped structure, and the bottom wall is inclined from the middle along the axis of the abutting roller 5 towards the axis, so that the abutting roller 5 in the abutting groove 7 has a conical structure that is large in the middle and thin at both ends, which facilitates the dispersion of the yarn in the abutting groove 7, thereby facilitating the dyeing treatment of the yarn in the atomizing nozzles 4 and improving the dyeing quality.

[0023] Reference Figure 1 and Figure 2 A collection hopper 8 is fixed inside the box 1 below the abutment roller 5. It is used to collect the dye liquor that does not act on the yarn and the abutment roller 5 during the dyeing process. It is also used to collect the dye liquor flowing downward from the abutment roller 5. The upper end of the collection hopper 8 is open and the two ends are closed. The two ends of the collection hopper 8 are connected to collection pipes 9. The two collection pipes 9 are respectively connected to the inlet pipes 6 at both ends of the feeding pipe 3. One of the collection pipes 9 is connected to a water pump 10 that allows the dye in the collection hopper 8 to enter the inlet pipe 6. The upper surface of the bottom plate of the collection hopper 8 is inclined downward toward the water pump 10 so that the dye liquor can be gathered near the water pump 10.

[0024] Reference Figure 1 and Figure 2 Inside the housing 1, there is a horizontally arranged mounting plate 11. A telescopic cylinder 12 is fixed on the mounting plate 11. The telescopic cylinder 12 is vertically arranged, and the connecting rod of the telescopic cylinder 12 is fixed on the feeding pipe 3. It is used to adjust the positional relationship between the atomizing nozzle 4 and the yarn.

[0025] Reference Figure 2The box 1 is equipped with an air outlet pipe 13, and several air outlet nozzles 14 are connected to the air outlet pipe 13. The air outlet nozzles 14 are directly facing several dyed yarns, which facilitates the drying and color fixing treatment of the dyed yarns. The box 1 is equipped with a blower 15, and the air outlet of the blower 15 is connected to an air supply pipe 16. The air supply pipe 16 is connected to the air outlet pipe 13, and a heating box 17 is connected to the air supply pipe 16. An electric heating wire for heating the air is fixedly installed in the heating box 17. The temperature of the air is controlled by the electric heating wire, which facilitates the drying of the yarns.

[0026] The implementation principle of this application embodiment is as follows: the yarn enters the housing 1 and moves forward under the action of the traction device. When the yarn passes the abutment roller 5, the worker evenly divides the yarn into several parts and guides them into different abutment grooves 7. After entering the abutment groove 7, the yarn is dyed by the corresponding atomizing nozzle 4.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
