Description

Technical Field

[0001] The utility model relates to the technical field of polyester fabric dyeing, in particular to a low-color-difference polyester fabric ultra-black dyeing processing device. Background Art

[0002] Polyester fabric is a fabric made of polyester (polyester fiber) as the main raw material. Polyester fabric is widely used in clothing, home textiles and other fields. The dyeing process of polyester fabric requires the use of a dyeing device. The dyeing device uses a special black darkening agent to significantly deepen the blackness of the black fabric. The special black darkening agent is used to reduce the amount of reflected light and improve the dyeing performance of polyester.

[0003] There is a device for uniformly dyeing ultra-black fabrics (its authorization announcement number is: CN216639956U); the lower clamping plate is manually moved to clamp the fabric between the upper and lower clamping plates, and the second movable rod is rotated through the hinged part by starting the second motor to stretch the fabric and make it flat. Then, the first motor is started to move the movable plate downward, and the fabric is immersed in the dyeing box to complete the dyeing.

[0004] However, this dyeing device has some shortcomings in actual use: the clamping method of the polyester fabric to be dyed by the upper and lower clamping plates will cause the clamping contact parts of the upper and lower clamping plates and the polyester fabric to be soaked and dyed unevenly with the special black darkening agent relative to other parts, which can easily cause color difference in the polyester fabric during the dyeing process; therefore, we propose a low-color-difference special black dyeing treatment device for polyester fabric to solve the above problems.

[0009] Preferably, the upward fitting mechanism includes a U-shaped frame, an extrusion wheel and a spring, the U-shaped frame is movably installed in the two side grooves, the extrusion wheel is rotatably installed in the U-shaped frame, and the top contact surface of the extrusion wheel squeezes the polyester fabric body upward and fits into the corresponding arc-shaped groove on the arc-shaped cam column; under the elastic force of the two springs, the extrusion wheel squeezes the polyester fabric body upward, so that the polyester fabric body is always clamped between the arc-shaped cam column and the extrusion wheel.

[0010] Preferably, the first transmission mechanism includes a first sprocket and a first chain, and the first sprocket is fixedly installed on one end of the rotating rod and the winding roller that rotates and extends out of the immersion and dyeing box, and the same first chain is meshed and installed between the two first sprockets; under the action of the first transmission mechanism, the arc-shaped cam column on the rotating rod is synchronously driven to rotate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The low-color-difference polyester fabric ultra-black dyeing processing device starts a motor to cause a winding roller to reel in a polyester fabric body. Simultaneously, under the action of a first transmission mechanism, the winding roller is synchronously driven to rotate an arc-shaped cam column on a rotating rod. Under the elastic force of two springs, an extrusion wheel is caused to upwardly squeeze the polyester fabric body, so that the polyester fabric body is always clamped between the arc-shaped cam column and the extrusion wheel. During the reciprocating rotation of the arc-shaped cam column, the polyester fabric body is swung up and down, so that the swinging polyester fabric body is fully immersed and dyed with an ultra-black darkening agent liquid in an immersion chamber, thereby ensuring uniform immersion and dyeing of the polyester fabric body and reducing color differences of the polyester fabric body caused by uneven immersion and dyeing.

The output shaft of the motor 13 is fixedly installed with one end of a winding roller 14, and the other end of the winding roller 14 rotates and extends out of the other second mounting plate 12. A winding roller 15 is rotatably installed between the two first mounting plates 11, and one end of the polyester fabric body 2 is wound around the winding roller 15. The other end of the polyester fabric body 2 passes around the arc cam column 6 and is wound around the winding roller 14. A first transmission mechanism is provided between the winding roller 14 and the rotating rod 5, and a second transmission mechanism is provided between the winding roller 15 and the rotating rod 5.

[0022] Furthermore, three arcuate grooves are formed on the arcuate cam column 6, and the three arcuate grooves on the arcuate cam column 6 are distributed in a circular array; when the arcuate cam column 6 rotates, the polyester fabric body 2 below the arcuate cam column 6 swings up and down reciprocatingly.

[0023] Specifically, the upward fitting mechanism includes a U-shaped frame 8, an extrusion wheel 9 and a spring 10. The U-shaped frame 8 is movably installed in the two side grooves 7, and the extrusion wheel 9 is rotatably installed in the U-shaped frame 8.
