Description

Technical Field

[0001] The present invention belongs to the technical field of cashmere fabrics, and particularly relates to a waterproof finishing device for cashmere fabrics. Background Art

[0002] Cashmere fabrics are highly favored for their softness, comfort, and good air permeability. As a high-end fabric, however, they do not inherently possess waterproof functionality. To improve the waterproof performance of cashmere fabrics, waterproof treatment is required.

[0003] For general fabrics, common waterproof treatment methods include: immersing the fabric in a solution containing a waterproof treatment agent multiple times and then drying; applying a waterproof coating. For cashmere fabrics, applying a waterproof coating can affect the texture of the cashmere fabric and also its air permeability. Moreover, the felting characteristics of cashmere fabrics make them prone to felting during immersion rolling. Summary of the Invention

[0004] The purpose of the present invention is to provide a waterproof finishing device for cashmere fabrics in order to solve the above problems.

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

[0006] A waterproof finishing device for cashmere fabrics includes a treatment tank and several guide rollers. A working chamber with an open top is provided in the treatment tank. The fabric is transmitted by the guide rollers and seals the opening of the working chamber. The pressure difference is generated in the working chamber through a pressure generating device to enable the medicament solution to penetrate the fabric. A support device for supporting the fabric is also provided at the opening of the working chamber. The support device includes at least two transmission rollers and a transmission belt assembly disposed on the transmission rollers. The transmission belt assembly has irregularly distributed holes, and the transmission belt assembly is driven by a driving component to move relative to the fabric.

[0007] As a further optimized solution of the present invention, first guide rollers are respectively provided at the inlet and outlet of the treatment tank. The two sides of the treatment tank extend inward to form a fabric channel adapted to the width of the fabric. Second guide rollers are respectively provided at the inlet and outlet of the fabric channel. The cashmere fabric enters and exits the treatment tank through the guide rollers, and the second guide rollers are used to guide the cashmere fabric at the outlet of the working chamber to facilitate the penetration of the medicament solution through the cashmere fabric.

[0008] As a further optimized solution of the present invention, the working chamber is formed by a side wall formed by the side of the fabric channel, a bottom wall formed by the bottom of the treatment tank, and an end wall formed by a partition provided at the bottom of the treatment tank. The position of the working chamber specifically proposed in this solution facilitates the efficient operation of the working chamber.

[0009] As a further optimized solution of the present invention, the conveyor belt assembly is constructed by a number of transverse ribs parallel to the conveyor rollers and a number of flexible connectors connected between the transverse ribs. Among them, the distances between the number of transverse ribs and the positions of the flexible connectors are irregularly distributed, and a flange is provided at the edge of the conveyor roller. By setting the conveyor belt assembly of this solution, the conveyor belt assembly can provide complete support for the cashmere fabric and has better permeability. In order to prevent part of the cashmere fabric from being blocked by the conveyor belt assembly due to the synchronous movement of the cashmere fabric and the conveyor belt assembly, during the transmission process, the relative contact position between the conveyor belt assembly and the cashmere fabric is continuously changed, so that the originally covered area of the cashmere fabric is exposed. Thus, by setting the transverse ribs and the flexible longitudinal connectors, a large range of irregularly distributed holes can be set, making the process of changing the contact position more efficient.

[0010] As a further optimized solution of the present invention, the pressure generating device includes a sealed liquid storage chamber, a connecting pipe connecting the working chamber and the liquid storage chamber, an air pump provided at the top of the liquid storage chamber, and a valve connecting the liquid storage chamber and the treatment tank. Among them, the bottom height of the liquid storage chamber is higher than the height of the medicament solution in the treatment tank. In this solution, by pumping the gas inside the liquid storage chamber, the liquid level of the liquid storage chamber rises, and then the medicament solution in the working chamber is pumped out, so that the medicament solution passes through the cashmere fabric from top to bottom.

[0011] As a further optimized solution of the present invention, a driving assembly is also provided at the connection between the connecting pipe and the working chamber, which is used to drive the relative movement between the conveyor belt assembly and the fabric during the working interval of the pressure generating device. When the pressure generating device is working, the medicament solution continuously passes through the surface of the cashmere fabric. At this time, the cashmere fabric adheres to the conveyor belt assembly due to the pressure difference, and the conveyor belt assembly can rotate freely, so it does not affect the continuous transmission of the cashmere fabric. When the pressure generating device completes a cycle of work, the cashmere fabric stops transmission through the external driving roller device, and there is no contact pressure between the cashmere fabric and the conveyor belt assembly. At this time, the conveyor belt assembly is actively moved to switch the contact position between the conveyor belt assembly and the cashmere fabric, and then enter the next working cycle of the pressure generating device.

[0012] As a further optimization solution of the present invention, the driving assembly includes a gear extending from the side wall of the fabric channel. A toothed ring corresponding to the gear is provided at the shaft end of the transmission roller, and the toothed ring is connected to the shaft end of the transmission roller through a one-way bearing. The driving assembly further includes a sliding groove body, and an air flotation valve is arranged in the sliding groove body. Among them, a support rod extends from the top of the air flotation valve, and a rack for driving the gear to rotate is arranged at the end of the support rod. An annular groove is arranged on the inner side wall of the sliding groove body, and the connecting pipe communicates with the working chamber through the annular groove and the sliding groove body. This solution specifically proposes a driving assembly. By setting the air flotation valve in this solution, when the pressure generating device extracts the medicament solution from the working chamber, the air flotation valve moves downward due to the differential pressure and does not drive the transmission roller to rotate due to the action of the one-way bearing. When the air flotation valve moves upward, it drives the transmission roller to rotate through the gear and the toothed ring, driving the conveyor belt assembly to change its position.

[0013] As a further optimization solution of the present invention, a side groove is provided on the fabric channel, and the side groove is used to accommodate the toothed ring, the gear, and the rack, so that the width of the fabric channel can be adapted to the width of the cashmere fabric, reducing the gap.

[0014] The beneficial effects of the present invention are as follows:

[0015] By forming a pressure difference on both sides of the cashmere fabric, the present invention promotes the penetration of the medicament solution through the cashmere fabric, replacing the padding process. And by providing a support device in the form of a conveyor belt to support the cashmere fabric, it prevents the cashmere fabric from being unable to maintain its posture under the pressure difference after being suspended. And irregular through holes are provided on the surface of the support device to prevent the local area of the cashmere fabric from being blocked after adjusting the contact position with the cashmere fabric, resulting in poor penetration effect of the medicament solution. Compared with padding, a softer method is adopted to waterproof the cashmere fabric, slowing down the felting deformation of the cashmere fabric. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0024] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0025] Embodiment 1

[0026] As Figure 1-7 shown, a waterproof finishing device for cashmere fabric includes a treatment tank 1 and several guide rollers. A working chamber 15 with an open top is provided in the treatment tank 1. The fabric is transmitted by the guide rollers and seals the opening of the working chamber 15. The pressure difference is generated in the working chamber 15 through the pressure generating device 3 so that the medicament solution penetrates through the fabric. A support device 2 for supporting the fabric is further provided at the opening of the working chamber 15. The support device 2 includes at least two transmission rollers 21 and a transmission belt assembly 23 provided on the transmission rollers 21. The transmission belt assembly 23 has irregularly distributed holes, and the transmission belt assembly 23 is driven by the driving assembly 4 to move relative to the fabric.

[0027] In this solution, a pressure difference is formed on both sides of the cashmere fabric to promote the penetration of the medicament solution through the cashmere fabric, replacing the padding process. The support device 2 in the form of a transmission belt is provided to support the cashmere fabric, preventing the cashmere fabric from being unable to maintain its posture under the pressure difference after being suspended. Irregular through holes are provided on the surface of the support device 2 to prevent partial shielding of the cashmere fabric after adjusting the contact position with the cashmere fabric, resulting in poor penetration effect of the medicament solution. Compared with padding, a softer method is used to perform waterproof treatment on the cashmere fabric, slowing down the felting and deformation of the cashmere fabric.

[0028] At the inlet and outlet of the treatment tank 1, there are respectively provided first guide rollers 12. On both sides of the treatment tank 1, there extend inwards to form a fabric channel 11 adapted to the width of the fabric. At the inlet and outlet of the fabric channel 11, there are respectively provided second guide rollers 13. The guide rollers are used to make the cashmere fabric enter and exit the treatment tank, and the second guide rollers 13 are used to guide the cashmere fabric at the outlet of the working chamber 15 so that the medicament solution can penetrate through the cashmere fabric.

[0029] The working chamber 15 is formed by a side wall formed on the side of the fabric channel 11, a bottom wall formed on the bottom of the treatment tank 1, and an end wall formed by a partition 14 provided on the bottom of the treatment tank 1. The position of the working chamber 15 specifically proposed in this solution is for the efficient operation of the working chamber 15.

[0030] The conveyor belt assembly 23 is constructed by a plurality of transverse ribs 24 parallel to the conveyor rollers 21 and a plurality of flexible connectors 25 connected between the transverse ribs 24. The spacing between the plurality of transverse ribs 24 and the positions of the flexible connectors 25 are irregularly distributed. And there are flanges 22 provided at the edges of the conveyor rollers 21. By setting the conveyor belt assembly 23 of this solution, the conveyor belt assembly 23 can provide complete support for the cashmere fabric and has better permeability. And in order to prevent part of the cashmere fabric from being blocked by the conveyor belt assembly 23 due to the synchronous movement of the cashmere fabric and the conveyor belt assembly 23, during the transmission process, the relative contact position between the conveyor belt assembly 23 and the cashmere fabric is continuously changed so that the originally blocked area of the cashmere fabric is exposed. Thus, by setting the transverse ribs 24 and the flexible connectors 25, holes with a large range of irregular distributions can be set, making the process of changing the contact position more efficient.

[0031] The pressure generating device 3 includes a sealed liquid storage chamber 31, a connecting pipe 32 connecting the working chamber 15 and the liquid storage chamber 31, an air pump 33 provided on the top of the liquid storage chamber 31, and a valve 34 connecting the liquid storage chamber 31 and the treatment tank 1. Among them, the bottom height of the liquid storage chamber 31 is higher than the height of the medicament solution in the treatment tank 1. In this solution, by pumping out the gas inside the liquid storage chamber 31, the liquid level of the liquid storage chamber 31 rises, and then the medicament solution in the working chamber 15 is pumped out, so that the medicament solution penetrates through the cashmere fabric from top to bottom.

[0032] A driving component 4 is also provided at the connection between the connecting pipe 32 and the working chamber 15, which is used to drive the relative movement between the conveyor belt assembly 23 and the fabric during the working interval of the pressure generating device 3. When the pressure generating device 3 is working, the medicament solution continuously penetrates through the surface of the cashmere fabric. At this time, the cashmere fabric adheres to the conveyor belt assembly 23 due to the pressure difference. The conveyor belt assembly 23 can rotate freely under the traction of the cashmere fabric, so it does not affect the continuous transmission of the cashmere fabric. When the pressure generating device 3 completes a cycle of work, the cashmere fabric stops transmitting through the external driving roller device, and there is no contact pressure between the cashmere fabric and the conveyor belt assembly 23. At this time, the conveyor belt assembly 23 is actively moved to switch the contact position between the conveyor belt assembly 23 and the cashmere fabric, and then enter the next working cycle of the pressure generating device 3.

[0033] The driving component 4 includes a gear 46 extending from the side wall of the fabric channel 11. A tooth ring 26 corresponding to the gear 46 is provided at the shaft end of the transmission roller 21, and the tooth ring 26 is connected to the shaft end of the transmission roller 21 through a one-way bearing 27. The driving component 4 also includes a sliding groove body 41. An air flotation valve 43 is arranged in the sliding groove body 41. Among them, a support rod 44 extends from the top of the air flotation valve 43, and a rack 45 for driving the gear 46 to rotate is arranged at the end of the support rod 44. A ring groove 42 is arranged on the inner side wall of the sliding groove body 41. The connecting pipe 32 is communicated with the working chamber 15 through the ring groove 42 and the sliding groove body 41. This solution specifically proposes a driving component 4. By setting the air flotation valve 43, when the pressure generating device 3 extracts the medicament solution from the working chamber 15, the air flotation valve 43 moves downward due to the differential pressure and does not drive the transmission roller 21 to rotate due to the action of the one-way bearing 27. When the pressure generating component 3 no longer extracts the medicament solution, the air pressure in the liquid storage chamber 31 is restored, and the air flotation valve 43 moves upward, then drives the transmission roller 21 to rotate through the rack 45, the gear 46, and the tooth ring 26, driving the conveyor belt assembly 23 to change its position.

[0034] A side groove 16 is opened on the fabric channel 11. The side groove 16 is used to accommodate the tooth ring 26, the gear 46, and the rack 45, so that the width of the fabric channel 11 can be adapted to the width of the cashmere fabric, reducing the gap.

[0035] The implementation mode is specifically as follows: The cashmere fabric is pulled by the external transmission device through the treatment tank 1. The air pump 33 extracts the air in the liquid storage cavity 31, causing the liquid level in the liquid storage cavity 31 to rise and the air float valve 43 to descend. The medicament solution in the treatment tank 1 enters the working cavity 15, the sliding groove body 41, and the connecting pipe 32 in sequence through the cashmere fabric and then enters the liquid storage cavity 31. After the liquid storage cavity 31 is full, at this time, the external transmission device stops pulling the cashmere fabric, restores the air pressure in the liquid storage cavity 31, and opens the valve 34, so that the medicament solution flows back into the treatment tank 1 through the valve 34. The air float valve 43 rises, causing the conveyor belt assembly 23 to rotate a certain distance and adjusting the contact position between the conveyor belt assembly 23 and the cashmere fabric. And so on. When the pressure generating device 3 continues to operate in the next cycle, the valve 34 is closed and the air float valve 43 moves downward. The downward movement of the air float valve 43 will not drive the transmission roller 21 to rotate through the one-way bearing 27, so as to enter the next working cycle.

[0036] The above-mentioned embodiments only represent several implementation modes of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
