Description

Technical Field

[0001] This invention belongs to the technical field of fabric finishing equipment, specifically relating to a finishing device for improving the drape of cashmere fabrics. Background Technology

[0002] Cashmere fabrics are loved by consumers for their excellent warmth retention. In the actual processing of cashmere fabrics, to improve the hand feel and further enhance their drape, a softening finishing process is performed. Softening finishing can be achieved in several ways. One method is to use mechanical methods to repeatedly rub the fabric under tension to reduce its rigidity and restore it to an appropriate softness. However, this finishing method is not washable. Generally, it is combined with a softening agent to reduce the coefficient of friction between fibers and increase lubrication, thereby giving the fabric a soft and smooth touch and better drape.

[0003] In existing technologies, devices for softening finishing of fabrics, such as the warp-knitted fabric finishing process and equipment disclosed in CN116752318A, disclose a machine frame with a feeding device, a first guide device, a second guide device, a transverse rubbing device, an soaking tank, a longitudinal beating and softening device, and an ironing roller group fixed in sequence. The fabric is fed in a rope-like manner, passing through the feeding device, the first guide device, and the second guide device into the transverse rubbing device, where it undergoes repeated transverse rubbing. Then, it undergoes softening finishing in the soaking tank, followed by beating and impacting by the longitudinal beating and softening device. Finally, it is dried and shaped by the ironing roller group. This method achieves a softening effect through a combination of mechanical finishing as the primary process and chemical finishing as the secondary process. However, in practical applications, the effect of sufficient contact between the fabric and the finishing solution in the soaking tank is not ideal. Furthermore, while this patent discloses that it primarily uses mechanical finishing, the actual effect of mechanical finishing is inferior to the finishing performance of softening agents. Therefore, the resulting fabric is not very soft and washable, requiring further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a finishing device for improving the drape of cashmere fabrics in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] In a first aspect, the present invention provides a finishing apparatus for improving the drape of cashmere fabrics, comprising a treatment tank, a finishing chamber vertically inserted into the treatment tank, and a fabric transfer roller frame disposed outside the finishing chamber.

[0007] It also includes a swing immersion mechanism inclined inside the treatment tank and a fabric combing mechanism arranged vertically in the finishing chamber. The fabric transfer roller frame is used to transfer the cashmere fabric between the swing immersion mechanism and the fabric combing mechanism.

[0008] The outside of the treatment tank is equipped with a reciprocating rotating assembly that drives the fabric combing mechanism to move periodically. The reciprocating rotating assembly and the oscillating immersion mechanism are driven by the same external driving source. The external driving source drives the oscillating immersion mechanism to oscillate periodically so that the cashmere fabric being transported on it can be repeatedly immersed in the finishing liquid injected into the treatment tank. At the same time, the external driving source drives the reciprocating rotating assembly to drive the fabric combing mechanism to comb the cashmere fabric being transported to the finishing chamber.

[0009] As a further optimization of the present invention, the swing immersion mechanism includes a first rotating roller and a second rotating roller. Both ends of the first rotating roller are fixedly provided with a linkage frame. The end of the linkage frame that is not connected to the first rotating roller is provided with a sector gear. The sector gear is fixed to the end of the second rotating roller. The tooth end of the sector gear meshes with a first transmission gear. A first limiting swing rod is movably fitted on the linkage frame. The end of the first limiting swing rod that is not connected to the linkage frame is sleeved on the drive shaft of an external drive source.

[0010] As a further optimization of the present invention, a plurality of disturbance rods are evenly arranged on the side surface of the transmission gear one that is away from the limiting swing rod one.

[0011] As a further optimization of the present invention, the reciprocating rotation assembly includes a second limiting swing rod sleeved on the drive shaft of an external drive source and a second transmission gear sleeved on the drive end of the fabric combing mechanism. The outer end of the second limiting swing rod is movably fitted with a T-shaped swing frame. The outer side of the treatment pool is provided with a limiting roller that slides with the T-shaped swing frame, and the end of the T-shaped swing frame away from the second limiting swing rod is provided with a tooth that drives with the second transmission gear.

[0012] As a further optimization of the present invention, the fabric combing mechanism includes two drive rollers arranged at both ends along the vertical direction inside the combing chamber and a linkage belt arranged between the two drive rollers. Combing components are respectively provided at both ends of the linkage belt, and a spring seat with one end connected to the combing component is provided inside the combing chamber.

[0013] As a further optimization of the present invention, the finishing chamber is provided with a residual liquid recovery mechanism, which includes a suction pump and a hollow filter cartridge disposed between the two combing components. The hollow filter cartridge extends through the finishing chamber and its extended end is connected to a transmission pipe, which is connected to the inlet end of the suction pump. The outlet end of the suction pump is connected to a discharge pipe that extends into the treatment tank.

[0014] As a further optimization of the present invention, the combing assembly includes a base, a combing head disposed at the front end of the base and in contact with the cashmere fabric, multiple rollers axially connected inside the combing head, and a vibrating seat rotatably disposed at the rear end of the base. A spring is provided between one end of the vibrating seat and the base. A transmission rack is provided on the linkage belt facing the combing head. The tail end of the vibrating seat is in contact with the transmission rack, and the front end of the vibrating seat is in contact with the cashmere fabric. An air gun assembly is embedded in the combing head.

[0015] As a further optimization of the present invention, the top of the finishing chamber is provided with a top cover and the middle of the top cover is provided with a through groove for cashmere fabric to pass through.

[0016] The beneficial effects of this invention are as follows:

[0017] (1) The present invention utilizes the same external driving source to drive the oscillating immersion mechanism to oscillate periodically, so that the cashmere fabric conveyed on it can be repeatedly immersed in the finishing liquid injected in the treatment tank. At the same time, the external driving source drives the reciprocating rotating component to drive the fabric combing mechanism to comb the cashmere fabric conveyed to the finishing chamber. The device has good linkage, which can improve the immersion effect and the finishing liquid penetration effect, and promote the cashmere fabric to obtain a soft and smooth touch feel, as well as better drape performance.

[0018] (2) The residual liquid recovery mechanism of the present invention is conducive to the recycling of finishing liquid. At the same time, when the cashmere fabric is conveyed on the combing mechanism, the suction force generated by the residual liquid recovery mechanism can also help to comb and unfold the surface fibers of the wool fabric, thereby playing a certain role in achieving the finishing effect of the fabric surface.

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Example 1

[0028] This embodiment provides a finishing device for improving the drape of cashmere fabrics during the softening process, such as... Figure 1 and Figure 2 As shown, the structure of the finishing device includes a treatment tank 1, a finishing chamber 3 vertically inserted into the treatment tank 1, and a fabric transfer roller frame 2 disposed outside the finishing chamber 3.

[0029] It also includes an inclined oscillating immersion mechanism 4 inside the treatment tank 1 and a fabric combing mechanism 6 arranged vertically inside the finishing chamber 3. The fabric transfer roller frame 2 is used to transfer the cashmere fabric between the oscillating immersion mechanism 4 and the fabric combing mechanism 6.

[0030] The outside of the treatment tank 1 is provided with a reciprocating rotating component 7 that drives the fabric combing mechanism 6 to move periodically. The reciprocating rotating component 7 and the oscillating immersion mechanism 4 are driven by the same external driving source. The external driving source drives the oscillating immersion mechanism 4 to oscillate periodically so that the cashmere fabric conveyed on it is repeatedly immersed in the finishing liquid injected into the treatment tank 1.

[0031] Furthermore, such as Figure 2 and Figure 4-5As shown, the oscillating immersion mechanism 4 includes a first rotating roller 41 and a second rotating roller 42. A linkage frame 44 is fixedly mounted at both ends of the first rotating roller 41. A sector gear 43 is mounted at the end of the linkage frame 44 that is not connected to the first rotating roller 41. The sector gear 43 is fixed to the end of the second rotating roller 42. A transmission gear 46 meshes with the teeth of the sector gear 43. A limiting oscillating rod 45 is movably fitted onto the linkage frame 44. The end of the limiting oscillating rod 45 that is not connected to the linkage frame 44 is sleeved on the drive shaft of an external drive source. In specific applications, cashmere fabrics... Driven by the fabric transfer roller frame 2, the fabric is transferred between the first roller 41 and the second roller 42. At the same time, when the limiting swing rod 45 is driven to rotate by an external drive source, the limiting swing rod 45 drives the linkage frame 44 to oscillate periodically under the restriction of the linkage frame 44. When the linkage frame 44 oscillates, the first roller 41 fixed at its end also oscillates relative to the second roller 42. This causes the cashmere fabric between the first roller 41 and the second roller 42 to be repeatedly immersed in the softening liquid in the treatment tank 1, which has an oscillating effect and helps to improve the contact effect between the cashmere fabric and the softening liquid.

[0032] Furthermore, to improve the flow effect of the softening liquid in the treatment tank 1, multiple disturbance rods 47 are evenly arranged on the side of the transmission gear 46 away from the limiting swing rod 45. In specific application, as described above, when the linkage frame 44 oscillates periodically, it will drive the sector gear 43 connected to it to oscillate as well. When the sector gear 43 oscillates, the transmission gear 46 externally connected to it will rotate, thereby causing the disturbance rods 47 arranged on one side to rotate and disturb the softening liquid in the treatment tank 1, which helps the softening liquid to fully contact the fabric.

[0033] Furthermore, an external drive source drives the reciprocating rotation component 7 to drive the fabric combing mechanism 6 to perform a combing process on the cashmere fabric conveyed to the finishing chamber 3. Specifically, for example... Figure 1 As shown, the reciprocating rotation assembly 7 includes a limiting swing rod 74 sleeved on the drive shaft of an external drive source and a transmission gear 73 sleeved on the drive end of the fabric combing mechanism 6. The outer end of the limiting swing rod 74 is movably fitted with a T-shaped swing frame 71. The outer side of the treatment pool 1 is provided with a limiting roller 72 that slides with the T-shaped swing frame 71, and the end of the T-shaped swing frame 71 away from the limiting swing rod 74 is provided with a tooth that drives with the transmission gear 73.

[0034] The fabric combing mechanism 6 includes two drive rollers 61 arranged at both ends in the vertical direction inside the combing chamber 3 and a linkage belt 63 arranged between the two drive rollers 61. Combing components 62 are respectively provided at both ends of the linkage belt 63. A spring seat 65 with one end connected to the combing component 62 is provided inside the combing chamber 3.

[0035] In practical applications, after the limiting swing rod 74 is driven to rotate by an external drive source, under the structural constraint of the T-shaped swing frame 71, the T-shaped swing frame 71 produces horizontal reciprocating movement, causing the teeth at its end to engage with the transmission gear 73. The transmission gear 73 then produces periodic rotation. The transmission gear 73 is coaxially set with the transmission roller 61, and thus the transmission gear 73 can drive the transmission roller 61 to also produce periodic rotation. Under the linkage of the linkage belt 63, the combing components 62 at both ends of the transmission roller 61 can produce periodic displacement relative to the surface of the cashmere fabric, thereby promoting the penetration of the softening liquid into the fabric while combing the surface of the cashmere fabric.

[0036] Furthermore, such as Figure 3 As shown, the combing assembly 62 includes a base 621, a combing head 622 disposed at the front end of the base 621 and in contact with the cashmere fabric, multiple rollers 623 shafted inside the combing head 622, and a vibrating seat 624 rotatably disposed at the rear end of the base 621. A spring 625 is provided between one end of the vibrating seat 624 and the base 621. A transmission rack 64 is provided on the side of the linkage belt 63 facing the combing head 622. The tail end of the vibrating seat 624 is in contact with the transmission rack 64, and the front end of the vibrating seat 624 is in contact with the cashmere fabric. An air gun assembly 626 is embedded in the combing head 622. The reciprocating rotation assembly 7 drives the two combing assemblies 6 of the fabric combing mechanism 6. 2. When sliding relative to the surface of the cashmere fabric, the roller 623 of the carding head 622 at the front end of the base 621 contacts the surface of the cashmere fabric and rotates to smooth the fabric surface. At the same time, the airflow of the air gun assembly 626 helps to effectively comb the knotted fibers on the surface of the fabric, making the surface of the cashmere fabric smoother. When the carding assembly 62 slides relative to the surface of the cashmere fabric, the vibrating seat 624, which is axially connected to the base 621, is driven and engaged with the transmission rack 64, so that the vibrating seat 624 vibrates up and down. After its front end contacts the fabric, it drives the fabric to vibrate, causing the residual finishing liquid on the fabric to be shaken off. On the other hand, it can also promote the carding head 622 to comb the surface of the fabric.

[0037] Example 2

[0038] Based on Example 1, to further reduce the liquid retention rate of cashmere fabrics after finishing, in this example, as... Figure 2 , 6 As shown, a residual liquid recovery mechanism 5 is also provided on the sorting chamber 3. The residual liquid recovery mechanism 5 includes a suction pump 52 and a hollow filter cartridge 51 disposed between the two combing components 62. The hollow filter cartridge 51 extends through the sorting chamber 3 and its extended end is connected to a transmission pipe 53. The transmission pipe 53 is connected to the inlet end of the suction pump 52. The outlet end of the suction pump 52 is connected to a drain pipe 54 that extends into the treatment tank 1.

[0039] Furthermore, the top of the finishing chamber 3 is provided with a top cover 8 and the middle of the top cover 8 is provided with a through groove for cashmere fabric to pass through. The finished cashmere fabric will pass through the through groove on the top cover 8 before leaving the finishing chamber 3, which helps to straighten the surface of the cashmere fabric.

[0040] In practical application, the residual liquid recovery mechanism 5 transports the cashmere fabric along the periphery of the hollow filter cartridge 51. After the suction pump 52 is started, the suction force generated by it is transmitted to the cashmere fabric through the transmission pipe 53 and the hollow filter cartridge 51. The residual softening liquid on the surface of the cashmere fabric is sucked out. The finishing liquid sucked into the hollow filter cartridge 51 is transferred to the suction pump 52 through the essential oil transmission pipe 53 under the action of suction force and then reinjected into the treatment tank 1 through the drain pipe 54, which is conducive to the recycling of finishing liquid. In addition, as the cashmere fabric is transported outside the hollow filter cartridge 51, the suction force generated by the suction pump 52 can also help to comb and unfold the fibers on the surface of the wool fabric, thereby also playing a certain role in assisting the realization of the surface finishing effect of the fabric.

[0041] The embodiments described above are merely examples of several implementations of the present invention, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
