Description

Technical Field

[0001] The invention belongs to the technical field of fabric finishing equipment, and particularly relates to a finishing device for improving the whiteness of cashmere fabric. Background Art

[0002] Cashmere fabrics are loved by consumers for their excellent warmth retention properties. The finishing process for cashmere fabrics includes scouring, bleaching, mercerizing, and softening. Due to the influence of the raw material's growing environment, the wool used in cashmere fabrics is yellow or light yellow. Some products require a high degree of fabric whiteness, so cashmere fabrics need to be bleached to improve the fabric's whiteness. The pigments in the fabric are decolorized by chemical reactions. Common bleaching finishing methods include oxidative bleaching, reduction bleaching, and oxidative-reduction bleaching. The difference lies in the type of bleaching finishing agent used.

[0003] In the prior art, the method for fabric bleaching generally involves injecting a prepared bleaching finishing agent into a treatment tank, and then placing the fabric in the treatment tank for static bleaching or using a stirring device for disturbance bleaching. In actual application, these treatment methods not only fail to further improve the bleaching effect, but also have low bleaching efficiency, and the application effect needs to be further improved.

DETAILED DESCRIPTION

[0024] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] This embodiment provides a finishing device for improving the whiteness of cashmere fabrics in the bleaching and finishing process of cashmere fabrics. Figure 1-2As shown, it includes a treatment pool 1 and a base 2 arranged above the treatment pool 1. A bleaching finishing agent for whitening cashmere fabric is injected into the treatment pool 1. The bleaching agent is preferably an oxidizing bleaching agent. The oxidizing bleaching agent destroys the pigments and lipid substances of the cashmere fiber color through oxidation, thereby achieving the purpose of bleaching.

[0027] Furthermore, the process further comprises two conveying roller groups 3 arranged along both sides of the processing tank 1 for conveying cashmere fabrics. The cashmere fabrics conveyed from the previous process are first input along the conveying roller group 3 at one end of the processing tank 1 and then output from the conveying roller group 3 at the other end of the processing tank 1.

[0028] A transmission frame 4 is provided on the outside of the transmission roller group 3, and a swing seat 6 is hinged on the top of the transmission frame 4. Figure 2 As shown, the transmission roller group 3 includes a linkage frame 31 obliquely arranged in the treatment tank 1, and the two ends of the linkage frame 31 are respectively connected to the transmission roller 1 32 and the transmission roller 2 34, and the middle part of the linkage frame 31 is connected to the guide roller 33, and the two ends of the guide roller 33 are connected to the treatment tank 1.

[0029] Further, such as Figure 3 As shown, the transmission frame 4 includes a gantry frame 41, the two ends of the gantry frame 41 are axially connected to the two ends of the transmission roller 2 34, and a plurality of supports 42 are provided at the top of the gantry frame 41. A hinged rod 43 is hinged on the support 42, and the hinged rod 43 is connected to one end of the swing seat 6;

[0030] Furthermore, the finishing device also includes an oscillating unit 7 disposed between the two transmission roller groups 3 in the processing tank 1 , wherein the upper end of the oscillating unit 7 is hinged to the end of the swing seat 6 that is not connected to the transmission frame 4 .

[0031] Furthermore, the finishing device also includes a synchronous drive unit 5 provided on the base 2, the synchronous drive unit 5 includes a synchronous wheel set 52 and a rotating shaft 56 axially connected to the base 2, the active end of the synchronous wheel set 52 is connected to the drive motor 51, the two synchronous wheels of the synchronous wheel set 52 are sleeved with a transmission shaft 53, the transmission shaft 53 is sleeved with a cam member 54, a transmission lever 55 is fixedly sleeved on the rotating shaft 56, the outer end of the transmission lever 55 abuts against the outer side of the cam member 54, and the swing seat 6 is fixedly sleeved on the rotating shaft 56;

[0032] When the entire finishing device is in use, first, the cashmere fabric transferred from the previous process is first input along the conveying roller group 3 at one end of the processing tank 1 and then output from the conveying roller group 3 at the other end of the processing tank 1. The cashmere fabric passes through the middle of the oscillating unit 7 and the prepared bleaching finishing liquid is injected into the processing tank 1. The liquid level of the bleaching finishing liquid in the processing tank 1 is higher than the lowest point of the lower end of the oscillating unit 7 when it is not working.

[0033] The synchronous drive unit 5 is started, and the drive motor 51 drives the two synchronous wheel sets 52, which in turn cause the two transmission shafts 53 to rotate in the same direction. After the two transmission shafts 53 rotate, the cam members 54 on them rotate. Because the diameters of the cam members 54 are different, as the cam members 54 rotate, they press against the transmission lever 55 and cause it to swing. The swinging transmission lever 55 drives the rotating shaft 56 to rotate, which in turn causes the swing seat 6 on the rotating shaft 56 to swing accordingly. The swing seat 6 then drives the transmission roller set 3 and the oscillating unit 7 hinged at both ends to swing up and down alternately.

[0034] Among them, when the transmission roller group 3 swings, the transmission roller 2 34 connected to the transmission frame 4 at one end and the transmission roller 1 32 at the other end will swing relative to the guide roller 33, and then the transmission roller 2 34 will further disturb the bleaching finishing liquid in the treatment tank 1. At the same time, when the transmission roller 2 34 and the transmission roller 1 32 swing, they will drive the cashmere fabric wound thereon to fully contact the bleaching finishing liquid. Similarly, when the oscillation unit 7 swings up and down, it will drive the cashmere fabric passing through it to immerse in the bleaching finishing liquid. When the oscillation unit 7 presses down, it will not only intensify the disturbance effect of the bleaching finishing liquid, but also promote the cashmere fabric to further fully contact the bleaching finishing liquid, resulting in a padding effect, thereby further improving the whiteness of the cashmere fabric after bleaching.

[0035] Example 2

[0036] In order to improve the bleaching finishing liquid and fully impregnate the cashmere fabric surface, this embodiment is based on the embodiment 1, and the structure of the oscillating unit 7 is designed. The oscillating unit 7 includes two gantry frames 71 hinged to the other end of the swing seat 6 and a limit seat 72 fixed to the bottom end of the two gantry frames 71. The top of the limit seat 72 is provided with a plurality of vertical cylinders 73 in a matrix. The bottom end of the vertical cylinder 73 is connected to the interior of the limit seat 72 and a nozzle 74 is fixed to the bottom end of the vertical cylinder 73. Figure 5 As shown, the inner bottom wall of the limiting seat 72 is evenly provided with a plurality of round rods 75 , and a through slot 76 is opened at a position between two adjacent round rods 75 on the inner bottom wall of the limiting seat 72 .

[0037] When the cashmere fabric passes through the middle of the oscillation unit 7, the round rod 75 provided on the limit seat 72 supports the cashmere fabric, and the bleaching finishing liquid in the treatment tank 1 overflows into the limit seat 72 through the through groove 76. The synchronous driving unit 5 drives the swing seat 6 to drive the oscillation unit 7 to swing up and down, so that the cashmere fabric is fully in contact with the bleaching finishing liquid in the limit seat 72, thereby improving the bleaching finishing effect.

[0038] In addition, the finishing device further increases the air flow disturbance unit 8 used in conjunction with the oscillation unit 7, such as Figure 2 and Figure 4As shown, the airflow disturbance unit 8 includes an air pump 81 arranged at the bottom of the base 2, and the air outlet of the air pump 81 is connected to the main air pipe 82, and the end of the main air pipe 82 not connected to the air pump 81 is connected to multiple branch air pipes 83, and the outside of the branch air pipe 83 is connected to a hollow piston rod 84, and the hollow piston rod 84 is correspondingly inserted into the vertical cylinder 73 and the extended end is abutted against the inner wall of the vertical cylinder 73, and a filter 85 is provided at the bottom of one end of the hollow piston rod 84 correspondingly inserted into the vertical cylinder 73.

[0039] During use, when the synchronous driving unit 5 drives the swing seat 6 to drive the oscillating unit 7 to swing downward, the limiting seat 72 drives the vertical cylinder 73 to move downward, so that the vertical cylinder 73 and the hollow piston rod 84 produce relative movement, and the space below the hollow piston rod 84 of the vertical cylinder 73 increases, so that the bleaching finishing liquid is sucked into the vertical cylinder 73 through the nozzle 74. As the synchronous driving unit 5 drives the swing seat 6 to drive the oscillating unit 7 to swing upward, the limiting seat 72 drives the vertical cylinder 73 to move upward, so that the vertical cylinder 73 and the hollow piston rod 84 produce relative movement, and the space below the hollow piston rod 84 of the vertical cylinder 73 is compressed, so that the bleaching finishing liquid is sprayed out of the vertical cylinder 73 from the nozzle 74 and sprayed onto the surface of the cashmere fabric located in the limiting seat 72;

[0040] In the above process, the high-pressure airflow generated by the air pump 81 is injected into the interior of the multiple hollow piston rods 84 through the main air pipe 82 and the branch air pipe 83, and is injected into the vertical cylinder 73 through the filter screen 85 at the lower end of the hollow piston rod 84. As the space of the vertical cylinder 73 below the hollow piston rod 84 is compressed, the high-pressure airflow is mixed with the bleaching finishing liquid and sprayed out from the nozzle 74 onto the surface of the cashmere fabric, promoting full contact between the bleaching finishing liquid and the cashmere fabric, further improving the bleaching finishing effect, and thus improving the whiteness of the cashmere fabric after post-finishing. In addition, the device provided by the present invention has good structural linkage, simple operation, and good application effect.

[0041] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
