Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a salt shrinkage device. Background Technology

[0002] Salt shrinkage is a widely used treatment method in the textile industry, primarily for fabric processing, especially for cotton and linen fabrics. After being treated in a hot, concentrated solution of neutral salts such as nitrates and calcium chloride, the fabric undergoes significant swelling and shrinkage. This salt shrinkage process achieves overall shrinkage, increasing warp and weft density, resulting in thicker yarns and a tighter, more textured feel.

[0003] However, during the salt shrinking process, the existing salt shrinking process is prone to problems such as the salt shrinking solution not penetrating the fabric well enough, resulting in poor uniformity. Utility Model Content

[0004] The main purpose of this invention is to propose a salt shrinkage device, which aims to solve the technical problem that the existing salt shrinkage process is prone to poor uniformity due to the insufficient penetration effect of the salt shrinkage solution into the fabric.

[0005] For the above objectives, the salt concentration device proposed in this utility model includes:

[0006] Machine tool;

[0007] An impregnation tank is installed on the machine and is filled with a salt solution to soak the fabric.

[0008] Active components, connected to the immersion tank; and

[0009] The padding assembly includes a first component and a second component that are separately configured. The first component is movably connected to the impregnation tank, and the second component is movably connected to the movable component. The first component and the second component cooperate to complete the padding of the fabric.

[0010] In one embodiment, three of the first components are spaced apart along the length of the immersion tank; and / or,

[0011] The second component is provided in three parts at intervals along the length of the immersion tank.

[0012] In one embodiment, the first component includes:

[0013] The immersion guide roller is installed in the immersion tank; and

[0014] An adjusting component is disposed inside the immersion tank and is movably connected to the immersion liquid guide roller so that the immersion liquid guide roller can move along the height direction of the immersion tank to adjust the distance between the immersion liquid guide roller and the second component in the height direction.

[0015] In one embodiment, the movable component includes a slide rail disposed at the edge of the immersion tank and extending along the length of the immersion tank, the slide rail being slidably connected to the second component to adjust the relative position of the second component and the first component.

[0016] In one embodiment, the second component includes:

[0017] The support frame is slidably connected to the slide rail;

[0018] The lower traction roller is rotatably connected to the support frame;

[0019] An upper traction roller, rotatably connected to the support frame and spaced apart from the lower traction roller in the vertical direction, such that the upper and lower traction rollers cooperate to form a liquid-rolling path; and

[0020] A driving component is connected to the lower traction roller to drive the lower traction roller to rotate, thereby pulling the fabric.

[0021] In one embodiment, the second component further includes an auxiliary guide roller rotatably connected to the support frame for guiding and pulling the fabric through the upper traction roller.

[0022] In one embodiment, the salt shrinkage device further includes a limiting member movably disposed on the support frame. The limiting member moves toward the slide rail, causing the limiting member to abut against the slide rail, or moves away from the slide rail, causing the limiting member to separate from the slide rail.

[0023] In one embodiment, the salt shrinking device further includes an unwinding assembly disposed on the machine base for unwinding the fabric so that the first component pulls the fabric.

[0024] In one embodiment, the salt shrinking equipment further includes a rolling assembly disposed on the machine base and located on the side of the impregnation cylinder opposite to the unwinding assembly, for rolling the fabric after impregnation.

[0025] In one embodiment, the salt shrinking device further includes a stacking box located at the end of the rolling assembly to receive the fabric output by the rolling assembly.

[0026] In the technical solution provided by this utility model, one end of the fabric is placed in an immersion tank, which is filled with a salt-condensing solution. The amount of salt-condensing solution is sufficient to completely immerse a first component, which rests against the top of the fabric to ensure that the fabric fully contacts the salt-condensing solution during immersion. Furthermore, the first component is movably connected to the immersion tank, allowing the first component to reach the deepest point of the fabric or a certain height in the salt-condensing solution, depending on the fabric material, thus better allowing the salt-condensing solution to penetrate different fabric materials. It is understood that the deeper the first component touches the fabric, the longer the immersion time; the shallower the contact, the shorter the immersion time. Then, a second component is used to introduce the soaked fabric into a rolling process. Pressure is applied to the fabric as it passes through the second component to squeeze out excess salt-condensing solution, thereby completing the salt-condensing treatment of the fabric. Moreover, the second component is movably connected to a movable component on the immersion tank, allowing adjustment of the time interval between immersion and rolling. By controlling the soaking time and the time interval between soaking and rolling, the salt shrinkage effect of the fabric can be effectively improved, and the uniformity of liquid application on the fabric can be increased.

Obviously, the described embodiments are only one part of the embodiments of the present utility model, and not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] For post-processing of fabrics, the salt shrinking process involves treating the fabric in a hot, concentrated solution of neutral salts such as nitrates and calcium chloride, resulting in significant swelling and shrinkage. After salt shrinking, the fabric shrinks comprehensively, increasing warp and weft density, making the yarn count thicker, and creating a tighter feel and textured surface. However, existing salt shrinking processes often suffer from insufficient penetration of the salt shrinking solution into the fabric, leading to poor uniformity.

[0038] In view of this, the present invention provides a salt shrinking device, which completes the immersion and rolling operations of the fabric by independently set first and second components respectively. The first component is movably connected to the immersion tank, and the immersion time can be adjusted according to different types of fabrics. The second component is movably connected to the movable component set on the immersion tank, and the time interval between immersion and rolling can be adjusted, thereby improving the salt shrinking effect of the fabric and increasing the uniformity of liquid on the fabric.

[0039] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a salt concentration device, comprising:

[0041] 10 machines;

[0042] The immersion tank 20 is installed on the machine 10 and is filled with a salt solution to soak the fabric.

[0043] Active component 30 is connected to immersion tank 20; and

[0044] The padding assembly 40 includes a first component 41 and a second component 42 that are separately arranged. The first component 41 is movably connected to the impregnation tank 20, and the second component 42 is movably connected to the movable assembly 30. The first component 41 and the second component 42 cooperate to make the fabric complete the padding.

[0045] In this embodiment, one end of the fabric is placed in an immersion tank 20, which is then filled with a salt-condensing solution. The amount of solution is sufficient to completely immerse the first component 41, which rests against the top of the fabric to ensure adequate contact with the solution during immersion. Furthermore, the first component 41 is movably connected to the immersion tank 20, allowing it to reach the deepest point or a certain height within the solution, depending on the fabric material, thus facilitating better penetration of the solution. It is understood that the deeper the first component 41 contacts the fabric, the longer the immersion time; conversely, the shallower the contact, the shorter the immersion time. Then, a second component 42 is used to introduce the immersed fabric into a rolling process. Pressure is applied to the fabric as it passes through the second component 42 to expel excess solution, thereby completing the salt-condensing treatment. Furthermore, the second component 42 is movably connected to the movable component 30 provided on the immersion tank 20, thereby allowing adjustment of the time interval between immersion and padding. By controlling the immersion time and the time interval between immersion and padding, the salt shrinkage effect of the fabric can be effectively improved, and the uniformity of liquid application on the fabric can be increased.

[0046] Specifically, the salt shrinkage equipment includes a machine base 10, an impregnation tank 20, a moving component 30, and an impregnation and rolling component 40.

[0047] The machine base 10 is the basic frame of the salt shrinking equipment, used to support and fix the immersion tank 20, the movable component 30, and the padding component 40, etc. It is typically constructed of metal to ensure the stability and durability of the equipment. The immersion tank 20 is mounted on the machine base 10 and is used to hold the salt shrinking solution. The fabric is immersed in the immersion tank 20 to absorb the salt shrinking solution, resulting in swelling and shrinkage. The structure of the immersion tank 20 is not specifically limited; for example, it can be rectangular or trapezoidal, as long as it ensures that the solution can penetrate the fabric evenly. The padding component 40 includes a first component 41 and a second component 42, which are separately arranged. The first component 41 guides and pulls the fabric to complete the immersion operation, and the second component 42 guides and pulls the immersed fabric to complete the padding operation. In this embodiment, the movable component 30 can be a guide rail or a conveyor belt connected to the immersion tank 20. The second component 42 can be adjusted relative to the first component 41 via the guide rail or conveyor belt to ensure that there is an appropriate time interval after the fabric has been immersed before padding. Understandably, if the time interval between soaking and padding is too short, the fabric may not have enough time to fully absorb the salt-shrinking solution, resulting in uneven salt-shrinking and affecting the final salt-shrinking quality and the fabric's feel. If the time interval is too long, the fabric may lose its wetness and begin to dry, affecting the fabric's absorption efficiency and uniformity of the salt-shrinking solution, leading to fabric shrinkage and affecting dimensional stability and wearing comfort. Regarding the fabric material, it can be plant fibers, seed fibers, or chemical fibers, but animal protein fibers are not suitable. Furthermore, for overall fabric salt-shrinking treatment, salt-shrinking printing can be performed. This can be done by printing before salt-shrinking, or salt-shrinking before printing, or by using salt-shrinking white paste for printing followed by precise digital printing, thus suitable for original and personalized clothing designs.

[0048] Furthermore, refer to Figure 1 , Figure 2 In one embodiment of this utility model, three first components 41 are spaced apart along the length of the immersion tank 20; and / or,

[0049] The second component 42 has three parts spaced apart along the length of the immersion tank 20.

[0050] In this embodiment, the technical solution allows the fabric to undergo three sequential immersion and padding operations, ensuring uniform absorption of the salt-curing solution. It is understood that fewer than three immersions and paddings may result in insufficient absorption of the salt-curing solution, affecting fabric uniformity and treatment effectiveness. Increasing the number of immersions and paddings beyond three may improve fabric uniformity and treatment effectiveness, but may also bring some negative effects. Excessive padding may waste the salt-curing solution, increase production costs, and may also affect the fabric's hand feel and texture due to overtreatment. Furthermore, excessive padding may increase processing time, reduce production efficiency, and may even damage the fabric, affecting its strength and durability.

[0051] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of this utility model, the first component 41 includes:

[0052] The immersion guide roller 411 is installed in the immersion tank 20; and

[0053] Adjusting component 412 is disposed inside the immersion tank 20 and is movably connected to the immersion guide roller 411 so that the immersion guide roller 411 moves along the height direction of the immersion tank 20 to adjust the distance between the immersion guide roller 411 and the second component 42 in the height direction.

[0054] In the technical solution adopted in this embodiment, the first component 41 may further include an immersion guide roller 411 and an adjusting member 412. The immersion guide roller 411 can press the fabric into the salt shrinkage solution, so that the fabric completes the immersion operation. The adjusting member 412 is movably connected to the immersion guide roller 411, so that the height of the immersion guide roller 411 in the immersion tank 20 can be adjusted according to the penetration effect of different fabric materials. It can be understood that the better the penetration effect of the fabric, the shallower the depth of the immersion guide roller 411 pressing the fabric against the salt shrinkage solution and the shorter the immersion time; the worse the penetration effect of the fabric, the deeper the depth of the immersion guide roller 411 pressing the fabric against the salt shrinkage solution and the longer the immersion time.

[0055] Furthermore, refer to Figure 1 , Figure 2 In one embodiment of the present invention, the movable component 30 includes a slide rail disposed on the edge of the immersion tank 20 and extending along the length direction of the immersion tank 20. The slide rail is slidably connected to the second component 42 to adjust the relative position of the second component 42 and the first component 41.

[0056] In the technical solution adopted in this embodiment, the movable component 30 may further include a slide rail. In this embodiment, the second component 42 can move along the slide rail, so that the distance and position between the first component 41 and the second component 42 can be adjusted as needed. It can be understood that adjusting the relative distance between the first component 41 and the second component 42 can control the time interval between the immersion operation and the rolling operation, thereby ensuring that the fabric has enough time to absorb the salt shrinkage solution.

[0057] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of this utility model, the second component 42 includes:

[0058] Support frame 421 is slidably connected to the slide rail;

[0059] The lower traction roller 422 is rotatably connected to the support frame 421;

[0060] The upper traction roller 423 is rotatably connected to the support frame 421 and spaced apart from the lower traction roller 422 in the vertical direction, so that the upper traction roller 423 and the lower traction roller 422 cooperate to form a rolling fluid path; and

[0061] The driving component 4 is connected to the lower traction roller 422 to drive the lower traction roller 422 to rotate, thereby pulling the fabric.

[0062] In this embodiment, the second component 42 may further include a support frame 421, a lower traction roller 422, an upper traction roller 423, and a driving component 4. In this embodiment, the support frame 421 provides sufficient structural strength for the second component 42, providing support. The second component 42 has opposing input and output ends. The input end is the side of the lower traction roller 422 facing away from the first component 41, and the output end is the side of the upper traction roller 423 close to the second component 42. The liquid-squeezing path winds from the input end to between the lower traction roller 422 and the upper traction roller 423, and then winds out from the output end. Thus, when the lower traction roller 422 pulls the fabric, the driving component 4 can drive the lower traction roller 422 to rotate, thereby allowing the fabric to complete the liquid-squeezing operation through the liquid-squeezing path to discharge excess salt solution. The distance between the lower traction roller 422 and the upper traction roller 423 can be set according to the fabric thickness and is not limited here.

[0063] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of the present invention, the second component 42 further includes an auxiliary guide roller 425, which is rotatably connected to the support frame 421 and is used to guide and pull the fabric passing through the upper traction roller 423.

[0064] In this embodiment, the auxiliary guide roller 425 guides the fabric through the upper traction roller 423, ensuring smooth fabric transfer during the liquid-pressing process, reducing fabric stretching and deformation, and guaranteeing uniform fabric processing. Preferably, the relative height of the auxiliary guide roller 425 is higher than the relative height of the upper traction roller 423.

[0065] Furthermore, refer to Figure 1 , Figure 3 In one embodiment of the present invention, the salt shrinkage device further includes a limiting member 50, which is movably disposed on the support frame 421. The limiting member 50 moves toward the slide rail so that the limiting member 50 abuts against the slide rail, or the limiting member 50 moves away from the slide rail so that the limiting member 50 separates from the slide rail.

[0066] In this embodiment, the salt shrinking equipment may further include a limiting member 50. The limiting member 50 may be a bolt or a screw, threadedly connected to the top of the support frame 421. By tightening the bolt or screw, the end of the bolt or screw moves towards the slide rail until it abuts against the slide rail, thus fixing the support frame 421. By loosening the bolt or screw, the end of the bolt or screw moves away from the slide rail until it separates from the slide rail, allowing the support frame 421 to slide. It is understood that the limiting member 50 ensures that the support frame 421 is accurately positioned in the desired location, improving the accuracy of the relative position between the first component 41 and the second component 42. Simultaneously, the limiting member 50 reduces the risk that the second component 42 may move beyond its predetermined position during the fabric impregnation process due to accident or operational error, ensuring the salt shrinking effect of the fabric.

[0067] Furthermore, refer to Figure 1 , Figure 2 In one embodiment of the present invention, the salt shrinking device further includes an unwinding assembly 60, which is disposed on the machine base 10 for unwinding the fabric so that the first component 41 pulls the fabric.

[0068] In this embodiment, the unwinding assembly 60 allows the fabric to be smoothly unfolded before entering the impregnation tank 20, reducing wrinkles and uneven tension, and improving the uniformity of the salt shrinking effect. In this embodiment, the unwinding assembly 60 may include an unwinding bracket and a roll shaft rotatably mounted on the unwinding bracket. The rolled fabric is placed onto the roll shaft, causing the roll shaft to rotate and unwind the fabric to begin the salt shrinking process. Of course, to improve the smoothness of fabric movement, a traction member can also be provided between the unwinding assembly 60 and the impregnation tank 20. One or more traction members can be provided, and multiple traction members can be spaced apart along the fabric's transmission direction; this is not limited here.

[0069] Furthermore, refer to Figure 1 , Figure 2 In one embodiment of the present invention, the salt shrinking equipment further includes a rolling assembly 70, which is disposed on the machine base 10 and located on the side of the impregnation cylinder 20 away from the unwinding assembly 60, for rolling the fabric that has been impregnated.

[0070] In this embodiment, the winding component 70 enables loose tension winding of the impregnated fabric, improving its hand feel and appearance, making it smoother and softer, and enhancing its overall quality. In this embodiment, the winding component 70 can be a winding machine, ensuring uniform tension of the fabric during the winding process.

[0071] Furthermore, refer to Figure 1 , Figure 2 In one embodiment of the present invention, the salt shrinking device further includes a stacking box 80, which is located at the end of the rolling assembly 70 to hold the fabric output by the rolling assembly 70.

[0072] In this embodiment, the fabric that has undergone dyeing is stored and managed in a specific manner using a stacking box 80, allowing the salt-curing solution sufficient time to diffuse and fix in the fabric, thereby improving the uniformity and fastness of dyeing. The stacking time of the fabric can be set according to different materials, and is not limited here.

[0073] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
