Description

Technical Field

[0001] The present application belongs to the technical field of textile equipment, and in particular relates to a pre-shrinkage mechanism for fabrics. Background Art

[0002] During the dyeing and finishing process, fabrics are subjected to tension in the warp direction, which reduces the warp buckling wave height and causes elongation. When hydrophilic fabrics are soaked in water, the fibers swell, increasing the diameters of the warp and weft yarns. This increases the warp buckling wave height and shortens the fabric, resulting in shrinkage. The percentage of this reduction in length relative to the original length is called the shrinkage rate. Current pre-shrinkage equipment often only wets one side of the fabric, preventing it from being fully moistened. Furthermore, the wetted fabric will drip during transport, adversely affecting processing equipment.

[0003] The invention patent with publication number CN108625060B discloses a textile fabric pre-shrinking machine, which includes a box body, a first conveying roller, a humidifying mechanism, a water supply mechanism, a drying mechanism, a second conveying roller, a discharge box, a drying mechanism and a third conveying roller.

[0004] The above patent absorbs water from the fabric through a sponge and dries the sponge through an air-drying box, so that the sponge can continuously absorb water from the fabric. Although the air-drying effect can be achieved on a mobile level, the air-drying efficiency is low, and it is easy for the sponge to be not completely dried and be sent out of the air-drying box to absorb water under the action of the motor and roller. This will lead to a decrease in the water absorption efficiency, thereby affecting the subsequent fabric drying, and needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a fabric pre-shrinkage mechanism that can solve the above problems.

[0006] The purpose of this application is to provide a pre-shrinking mechanism for fabrics, comprising a box body, a transmission mechanism, a humidifying mechanism, a water absorbing mechanism and a drying structure located in the box body; the water absorbing mechanism comprises:

[0007] The drying structure includes a drying box, an electric heating network and a fan arranged in the drying box;

[0008] The water absorption structure includes a water removal box, a driving motor arranged in the drying box, a roller body connected to the driving motor, and a sponge belt arranged on the roller body;

[0009] The squeezing structure is used to squeeze the sponge and squeeze out the water absorbed by the sponge;

[0010] The extrusion structure is arranged between the drying structure and the water absorbing structure, and the sponge belt passes through the dewatering box, the extrusion structure and the drying box in sequence.

[0011] The aforementioned fabric preshrinkage mechanism utilizes a transmission mechanism, a humidifying mechanism, a water absorbing mechanism, and a drying mechanism to achieve a complete preshrinkage process for the fabric, from humidification and water absorption to drying. This not only improves work efficiency but also ensures the stability and consistency of the preshrinkage effect. The drying, absorbing, and squeezing structures in the water absorbing mechanism work together to effectively absorb excess moisture from the fabric. The sponge belt's high water absorption allows it to quickly absorb moisture from the fabric surface, and the squeezing structure squeezes the moisture out of the sponge, achieving water recycling and efficient management. At the same time, the water collection structure allows the water generated by the spraying mechanism to be effectively collected and reused, reducing water waste.

[0012] Furthermore, the extrusion structure includes:

[0013] Squeeze box;

[0014] A driving assembly is arranged outside the extrusion box and extends into the extrusion box;

[0015] An extrusion assembly is connected to the driving assembly and includes an upper extrusion roller and a lower extrusion roller located on both sides of the cloth;

[0016] A recovery component is provided in the box and is used to recover water dripping after squeezing;

[0017] The extrusion box is located between the drying box and the water removal box.

[0018] The extrusion box is located between the drying box and the water removal tank, and is used to provide a stable environment so that the extrusion process can proceed smoothly, while preventing the water generated during the extrusion process from splashing or leaking. The driving assembly is arranged outside the extrusion box and extends into the extrusion box, and is used to provide power to drive the extrusion assembly to rotate or move, thereby achieving the extrusion of the sponge belt. The extrusion assembly is connected to the driving assembly, and includes an upper extrusion roller and a lower extrusion roller located on both sides of the fabric. While squeezing the sponge belt, it can protect the texture of the fabric from being damaged, and by adjusting the gap between the upper extrusion roller and the lower extrusion roller, the intensity and effect of the extrusion can be controlled. The recovery assembly is arranged in the box and is used to recover the water dripping after extrusion. It can quickly collect and discharge the water generated during the extrusion process to prevent the water from accumulating or overflowing in the box.

[0019] Through this design, the extrusion structure effectively squeezes out the moisture absorbed by the sponge belt, and the extruded moisture is recovered and processed by the recovery component. This not only improves the pre-shrinking effect of the fabric, but also reduces water waste, achieving energy conservation and environmental protection goals. Furthermore, because the extrusion box is located between the drying box and the dewatering tank, this layout makes the entire pre-shrinking mechanism's workflow smoother and more efficient.

[0020] Furthermore: the extrusion box is divided into an inlet chamber and an outlet chamber by a recovery component. The extrusion component is located in the inlet chamber, and the inlet chamber is used to introduce the sponge belt that has absorbed water, and the outlet chamber is used to export the dried sponge belt. After the extrusion component squeezes the sponge belt, the falling water is isolated and recovered by the recovery component.

[0021] The interior of the extrusion box is divided into two areas, an entry chamber and an exit chamber, by a recycling component, so that the sponge belt can enter and exit in an orderly manner during the processing process, avoiding confusion and cross-contamination. The extrusion component is located in the entry chamber and is responsible for squeezing the sponge belt after the fabric has absorbed moisture, squeezing out the moisture on the sponge belt, thereby improving the subsequent drying effect of the sponge belt. Before the sponge belt enters the extrusion box, it has absorbed excess moisture from the fabric in the dehydration tank. The entry chamber provides a smooth transition environment for the sponge belt, allowing it to smoothly enter the extrusion component for extrusion processing. The exit chamber is used to export the dried sponge belt. After the extrusion component completes the extrusion, most of the moisture on the sponge belt is squeezed out, and the sponge belt has become relatively dry at this time. After drying in the subsequent drying box, the exit chamber provides a safe exit for the sponge belt, allowing it to smoothly leave the extrusion box and enter the subsequent drying processing stage.

[0022] At the same time, the recovery component not only isolates the inlet cavity and the outlet cavity, but is also responsible for recovering the moisture that falls during the extrusion process. The recovery component can quickly collect and isolate the squeezed moisture, avoiding secondary contamination or impact on the dry sponge belt.

[0023] Furthermore, the driving assembly includes:

[0024] An upper end face gear is provided on one side of the upper extrusion roller;

[0025] A lower end face gear is provided on one side of the lower extrusion roller;

[0026] A long gear is provided on one side of the upper end face gear and the lower end face gear and meshes with the upper end face gear and the lower end face gear;

[0027] Wherein, a motor is provided on the output shaft of the long gear. The motor is located outside the extrusion box, and its output shaft extends into the interior of the extrusion box and is connected to the long gear.

[0028] An upper face gear is located on one side of the upper squeeze roller, while a lower face gear is located on the other side of the lower squeeze roller. These two gears drive the rotation of the upper and lower squeeze rollers, respectively. A long gear is located on either side of the upper and lower face gears and meshes with them, ensuring that when the long gear rotates, it simultaneously drives the upper and lower face gears, thereby driving the upper and lower squeeze rollers in synchronous operation. The motor is located outside the squeeze box, with its output shaft extending inside the squeeze box and connected to the long gear. This makes the motor easier to install and maintain, and also avoids the risk of contamination and damage caused by direct exposure to the squeeze box. By connecting the motor's output shaft to the long gear, power is transmitted. When the motor is started, its output shaft rotates, driving the long gear, which in turn drives the upper and lower face gears, as well as the upper and lower squeeze rollers, in synchronous rotation. This drive assembly design also makes the overall structure more compact. By placing the motor outside the squeeze box and using the long gear for power transmission, a complex transmission mechanism inside the squeeze box is avoided, thus reducing space requirements.

[0029] Furthermore, the recovery component includes a water collecting box, a water collecting plate and a water guide pipe. The water collecting plate is arranged between the inlet cavity and the outlet cavity to isolate the two cavities.

[0030] The water collection tank collects and stores water that falls during the extrusion process. A water collection plate is located between the inlet and outlet chambers, isolating the two chambers. When the extrusion assembly squeezes the sponge strip between the upper and lower extrusion rollers, the squeezed water drips onto the water collection plate, which is tilted at a certain angle to allow the water to flow smoothly into the water collection tank. A water pipe connects the water collection tank and the water collection plate, draining the water from the water collection tank for subsequent processing. The recovery component not only effectively collects and utilizes the water that falls during the extrusion process, but also prevents secondary contamination of the dried sponge strip.

[0031] Furthermore, the water collecting plate is arranged at an angle, and the water guide pipe is located at the lowest point of the water collecting plate.

[0032] The inclined setting of the water collecting plate can ensure that the water falling during the extrusion process can smoothly flow along the water collecting plate to its lowest point, effectively reducing the accumulation and retention time of water on the water collecting plate. The water guide pipe is located at the lowest point of the water collecting plate, which can ensure that all the water accumulated on the water collecting plate can smoothly flow into the water guide pipe, ensuring the complete recovery and utilization of the water.

[0033] The beneficial effects of this application are:

[0034] 1. Through the coordinated work of the transmission mechanism, humidification mechanism, water absorption mechanism and drying mechanism, a complete pre-shrinkage process of the fabric from humidification, water absorption to drying is realized, which not only improves the work efficiency but also ensures the stability and consistency of the pre-shrinkage effect;

[0035] 2. The drying structure, water absorption structure and extrusion structure in the water absorption mechanism work together to effectively absorb excess water on the fabric. The sponge belt is designed with high water absorption and can quickly absorb water from the surface of the fabric. The extrusion structure squeezes out the water on the sponge, thus achieving water recycling and efficient management.

[0036] 3. By arranging the upper end face gear, the lower end face gear, the long gear and the motor located outside, it is avoided to arrange a complicated transmission mechanism inside the extrusion box, thereby reducing the occupied space. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0045] The fabric pre-shrinking mechanism provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0046] Example 1:

[0047] like Figures 1 to 3 As shown, the embodiment of the present application provides a fabric pre-shrinking mechanism, including a housing 100, a transmission mechanism 110, a humidification mechanism 120, a water absorption mechanism 130 and a drying mechanism 140 located in the housing 100; the water absorption mechanism 130 includes:

[0048] The drying structure 200 includes a drying box 210, an electric heating network 220 and a fan 230 disposed in the drying box 210;

[0049] The water absorption structure 300 includes a water removal box 310, a driving motor 320 disposed in the drying box 210, a roller 330 connected to the driving motor 320, and a sponge belt 340 disposed on the roller 330;

[0050] The squeezing structure 400 is used to squeeze the sponge and squeeze out the water absorbed by the sponge;

[0051] The extrusion structure 400 is disposed between the drying structure 200 and the water absorbing structure 300 , and the sponge belt 340 passes through the dewatering box 310 , the extrusion structure 400 and the drying box 210 in sequence.

[0052] In some implementations of the embodiments of this application, Figure 1As shown, the aforementioned fabric preshrinkage mechanism is used, and through the coordinated operation of the transmission mechanism 110, the humidification mechanism 120, the water absorption mechanism 130, and the drying mechanism 140, a complete preshrinkage process for the fabric, from humidification and water absorption to drying, is achieved. This not only improves work efficiency but also ensures the stability and consistency of the preshrinkage effect. The drying structure 200, the water absorption structure 300, and the extrusion structure 400 in the water absorption mechanism 130 work together to effectively absorb excess moisture from the fabric. The sponge belt 340, with its high water absorption, is designed to quickly absorb moisture from the fabric surface and, through the extrusion structure 400, squeezes the moisture out of the sponge, achieving water recycling and efficient management. At the same time, the design of the water collection structure allows the running water generated by the spraying mechanism to be effectively collected and reused, reducing the waste of water resources.

[0053] Example 2:

[0054] An embodiment of the present application provides a fabric pre-shrinkage mechanism. In addition to the above-mentioned technical features, the fabric pre-shrinkage mechanism of the embodiment of the present application also includes the following technical features.

[0055] like Figure 2 and Figure 3 As shown, the extruded structure 400 includes:

[0056] Squeeze box 410;

[0057] The driving assembly 420 is disposed outside the extrusion box 410 and extends into the extrusion box 410;

[0058] The squeezing assembly 430 is connected to the driving assembly 420 and includes an upper squeezing roller 431 and a lower squeezing roller 432 located on both sides of the cloth;

[0059] A recovery component 440 is provided in the housing 100 and is used to recover water dripping after squeezing;

[0060] The squeezing box 410 is located between the drying box 210 and the water removal box 310 .

[0061] In an embodiment of the present application, the squeezing box 410 is located between the drying box 210 and the water removal tank 310, and is used to provide a stable environment so that the squeezing process can proceed smoothly while preventing the water generated during the squeezing process from splashing or leaking. The driving assembly 420 is arranged outside the squeezing box 410 and extends into the squeezing box 410, and is used to provide power to drive the squeezing assembly 430 to rotate or move, thereby squeezing the sponge belt 340. The squeezing assembly 430 is connected to the driving assembly 420, and includes an upper squeezing roller 431 and a lower squeezing roller 432 located on both sides of the fabric. While squeezing the sponge belt 340, the texture of the fabric is protected from damage, and by adjusting the gap between the upper squeezing roller 431 and the lower squeezing roller 432, the intensity and effect of the squeezing can be controlled. The recovery assembly 440 is arranged in the box body 100 and is used to recover the water dripping after squeezing. It can quickly collect and discharge the water generated during the squeezing process to prevent the water from accumulating or overflowing in the box body 100.

[0062] Through this design, the squeezing structure 400 can effectively squeeze out the water absorbed by the sponge belt 340, and the squeezed water is recovered and processed by the recovery assembly 440. This not only improves the pre-shrinking effect of the fabric, but also reduces water waste, achieving energy conservation and environmental protection goals. Furthermore, because the squeezing box 410 is located between the drying box 210 and the water removal box 310, this layout makes the entire pre-shrinking mechanism's workflow smoother and more efficient.

[0063] Moreover, the extrusion box 410 is divided into an inlet chamber 411 and an outlet chamber 412 through a recovery component 440. The extrusion component 430 is located in the inlet chamber 411, and the inlet chamber 411 is used to introduce the sponge belt 340 that has absorbed water, and the outlet chamber 412 is used to export the dried sponge belt 340. After the extrusion component 430 squeezes the sponge belt 340, the falling water is isolated and recovered by the recovery component 440.

[0064] In some embodiments of the present application, the interior of the extrusion box 410 is divided into two areas, an entry chamber 411 and an exit chamber 412, by a recovery assembly 440, so that the sponge belt 340 can enter and exit in an orderly manner during the processing process, avoiding confusion and cross-contamination. The extrusion assembly 430 is located in the entry chamber 411 and is responsible for squeezing the sponge belt 340 after the fabric has absorbed moisture, squeezing out the moisture on the sponge belt 340, thereby improving the subsequent drying effect of the sponge belt 340. Before the sponge belt 340 enters the extrusion box 410, it has absorbed excess moisture on the fabric in the dewatering tank 310. The entry chamber 411 provides a smooth transition environment for the sponge belt 340, allowing it to smoothly enter the extrusion assembly 430 for extrusion processing. The export cavity 412 is used to export the dried sponge belt 340. After the extrusion component 430 completes the extrusion, most of the moisture on the sponge belt 340 is squeezed out. At this time, the sponge belt 340 has become relatively dry. After drying in the subsequent drying box 210, the export cavity 412 provides a safe exit for the sponge belt 340, so that it can smoothly leave the extrusion box 410 and enter the subsequent drying process stage.

[0065] At the same time, the recovery component 440 not only isolates the inlet cavity 411 and the outlet cavity 412, but is also responsible for recovering the moisture dropped during the extrusion process. The recovery component 440 can quickly collect and isolate the squeezed moisture, avoiding secondary contamination or impact on the dry sponge belt 340.

[0066] Example 3:

[0067] An embodiment of the present application provides a fabric pre-shrinkage mechanism. In addition to the above-mentioned technical features, the fabric pre-shrinkage mechanism of the embodiment of the present application also includes the following technical features.

[0068] like Figure 4 and Figure 5 As shown, the drive assembly 420 includes:

[0069] The upper end face gear 421 is provided on one side of the upper squeezing roller 431;

[0070] The lower end face gear 422 is provided on one side of the lower squeezing roller 432;

[0071] The long gear 423 is provided on one side of the upper end face gear 421 and the lower end face gear 422 and meshes with the upper end face gear 421 and the lower end face gear 422;

[0072] A motor is provided on the output shaft of the long gear 423 . The motor is located outside the extrusion box 410 , and its output shaft extends into the interior of the extrusion box 410 and is connected to the long gear 423 .

[0073] In the embodiment of the present application, the upper end face gear 421 is arranged on one side of the upper extrusion roller 431, and the lower end face gear 422 is arranged on one side of the lower extrusion roller 432. These two gears are responsible for driving the rotation of the upper extrusion roller 431 and the lower extrusion roller 432 respectively. The long gear 423 is arranged on one side of the upper end face gear 421 and the lower end face gear 422 and meshes with them, ensuring that when the long gear 423 rotates, it can simultaneously drive the upper end face gear 421 and the lower end face gear 422 to rotate, thereby driving the upper extrusion roller 431 and the lower extrusion roller 432 to work synchronously. The motor is located outside the extrusion box 410, and its output shaft extends to the inside of the extrusion box 410 and is connected to the long gear 423, making the installation and maintenance of the motor more convenient, and also avoiding the risk of contamination and damage that may be caused by the motor being directly exposed to the inside of the extrusion box 410. By connecting the motor's output shaft to the long gear 423, power transmission is achieved. When the motor is started, its output shaft rotates, driving the long gear 423 to rotate, thereby driving the synchronous rotation of the upper and lower end gears 421, 422, and the upper and lower squeeze rollers 431, 432. Furthermore, the design of the drive assembly 420 makes the overall structure more compact. By placing the motor outside the squeeze box 410 and utilizing the long gear 423 for power transmission, a complex transmission mechanism within the squeeze box 410 is avoided, thereby reducing space usage.

[0074] Example 4:

[0075] An embodiment of the present application provides a fabric pre-shrinkage mechanism. In addition to the above-mentioned technical features, the fabric pre-shrinkage mechanism of the embodiment of the present application also includes the following technical features.

[0076] like Figures 1 to 3 As shown, the recovery assembly 440 includes a water collecting box 441, a water collecting plate 442 and a water guide pipe 443. The water collecting plate 442 is arranged between the inlet chamber 411 and the outlet chamber 412 to isolate the two chambers.

[0077] In the embodiment of the present application, the water collecting tank 441 is used to collect and store the water that falls during the extrusion process. The water collecting plate 442 is arranged between the inlet chamber 411 and the outlet chamber 412, which plays the role of isolating the two chambers. When the extrusion assembly 430 squeezes the sponge belt 340 between the upper extrusion roller 431 and the lower extrusion roller 432, the squeezed water will drip onto the water collecting plate 442, which has a certain inclination angle so that the water can flow smoothly into the water collecting tank 441. The water guide pipe 443 is used to connect the water collecting tank 441 and the water collecting plate 442 to guide the water in the water collecting tank 441 for subsequent processing. At the same time, the recovery assembly 440 not only realizes the effective collection and utilization of the water that falls during the extrusion process, but also avoids the secondary contamination of the dried sponge belt 340 by the water.

[0078] Furthermore, the water collecting plate 442 is arranged at an angle, and the water guide pipe 443 is located at the lowest point of the water collecting plate 442 .

[0079] In some embodiments of the present application, the inclined setting of the water collecting plate 442 can ensure that the water falling during the extrusion process can smoothly flow along the water collecting plate 442 to its lowest point, effectively reducing the accumulation and retention time of water on the water collecting plate 442. The water guide pipe 443 is located at the lowest point of the water collecting plate 442, which can ensure that all water accumulated on the water collecting plate 442 can smoothly flow into the water guide pipe 443, ensuring the complete recovery and utilization of the water.

[0080] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.
