[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] Reference Figures 1 to 2 This utility model provides a cold pad-batch dyeing and cooling device for knitted fabrics, including a support frame module with a feeding guide unit 110 and a feeding guide unit 120; a fabric guide module connected to the feeding guide unit 110 and the feeding guide unit 120; a cooling module connected to the support frame module and the fabric guide module; and a drive module including a first drive unit and a second drive unit. The first drive unit is connected to the support frame module and the fabric guide module, and the second drive unit is connected to the cooling module. The first drive unit drives the knitted fabric to move between the support frame module and the fabric guide module, and the second drive unit drives the knitted fabric to move between the cooling module. According to the technical solution of this embodiment, the knitted fabric can be cooled rapidly, effectively ensuring the flatness and aesthetics of the knitted fabric surface.

[0027] It should be noted that the support frame module is the main structure of the equipment, used to support and carry the knitted fabric during the dyeing and cooling processes. The feeding guide unit 110 and feeding guide unit 120 are located at opposite ends of the support frame module, guiding the knitted fabric into and out of the equipment. The fabric guide module ensures smooth and continuous movement of the knitted fabric on the support frame module. The cooling module cools the knitted fabric after dyeing by increasing the contact area between the fabric and the air surface to accelerate the cooling rate. Both the first and second drive units of the drive module drive corresponding pulleys or rollers via motors to move the knitted fabric within the equipment.

[0028] It should be noted that the cooling module can rapidly reduce the temperature of the knitted fabric after dyeing. The textile dyes hydrolyze due to high temperature or excessive diffusion, thereby improving the uniformity and fixation rate of the dyeing process. Compared with traditional knitted fabric dyeing processes, the cooling equipment in this embodiment eliminates the need for steaming steps, thus saving significant energy. Furthermore, the automated design of the fabric guiding module, cooling module, and drive module ensures smoother and more continuous movement of the knitted fabric during the cooling process, thereby increasing the cooling rate of the knitted fabric.

[0029] The support frame module includes a first support component 130, a second support component 140, and a third support component 150. One side of the first support component 130, the second support component 140, and the third support component 150 is connected to a first crossbeam 101 and a second crossbeam 102. The other side of the first support component 130, the second support component 140, and the third support component 150 is connected to a third crossbeam and a fourth crossbeam. A feeding guide unit 110 is disposed on the upper part of the first support component 130 and is connected to the first crossbeam 101 and the third crossbeam. A feeding guide unit 120 is disposed in the middle of the third support component 150. A cooling module and a guide cloth module are both connected to the second support component 140. A first drive unit and a second drive unit are both disposed inside the second support component 140.

[0030] It should be noted that the first support assembly 130, the second support assembly 140, and the third support assembly 150 are connected by the first crossbeam 101, the second crossbeam 102, the third crossbeam, and the fourth crossbeam, forming a stable frame structure for the cooling equipment. This enhances the overall strength of the support frame module and improves the deformation resistance of the cooling equipment. The feeding guide unit 110 is located on the upper part of the first support assembly 130 and connected to the first crossbeam 101 and the third crossbeam, ensuring that the knitted fabric can smoothly and accurately enter the cooling module through the guide module and reduce friction and damage to the knitted fabric during the feeding process. The feeding guide unit 120 is located in the middle of the third support assembly 150, facilitating the smooth discharge of the knitted fabric from the equipment after cooling.

[0031] Furthermore, both the cooling module and the guiding module are connected to the second support assembly 140, allowing the cooling and guiding processes of the knitted fabric to be completed within a relatively concentrated area. This improves the compactness and integration of the cooling equipment. The first drive unit, located within the second support assembly 140, drives the knitted fabric to move between the support frame module and the cooling module, ensuring the fabric passes smoothly and continuously through the cooling module and maintaining the uniformity of dyeing and cooling effects. The second drive unit, also located within the second support assembly 140, drives the cooling module to rotate, thereby cooling the knitted fabric. This dual-drive design not only improves the flexibility of the equipment but also ensures the stability and controllability of the fabric during the cooling process.

[0032] The first support assembly 130 is provided with a first pillar 131 and a second pillar 132; the second support assembly 140 is provided with a third pillar 141 and a fourth pillar 142; the third support assembly 150 is provided with a fifth pillar 151 and a sixth pillar 152; the feeding guide unit 120 is connected to the fifth pillar 151 and the sixth pillar 152; the guide module includes a first pulley 210, a second pulley 220, a third pulley 230, a fourth pulley 240, a fifth pulley 250, and a sixth pulley 260. The first pulley 210 is located on the upper part of the first support assembly 130 and is connected to the first pillar 131 and the second pillar 132; the second pulley 220, the third pulley 230, the fourth pulley 240, the fifth pulley 250, and the sixth pulley 260 are ... Four pulleys 240 are arranged from top to bottom between the third support column 141 and the fourth support column 142. The fifth pulley 250 and the sixth pulley 260 are arranged from bottom to top between the fifth support column 151 and the sixth support column 152. The first drive unit includes a first drive wheel 411, a second drive wheel 412 and a third drive wheel 413. The first drive wheel 411 and the second drive wheel 412 are arranged from top to bottom between the third support column 141 and the fourth support column 142. The third drive wheel 413 is arranged between the fifth support column 151 and the sixth support column 152 and is located on the upper part of the sixth pulley 260. The second drive unit is connected to the third support column 141, the fourth support column 142 and the cooling module respectively.

[0033] It should be noted that the first support component 130, the second support component 140 and the third support component 150 are each composed of two sets of pillars, providing a stable support foundation for the support frame module. The layout and design of multiple pillars ensure the structural stability of the entire equipment and can withstand various forces and vibrations generated during the cooling process of the cooling equipment.

[0034] The fabric guide module forms a continuous fabric path between the support pillars via the first pulley 210 to the sixth pulley 260, allowing the knitted fabric to pass smoothly and continuously through the cooling module. Multiple pulleys in the fabric guide module are arranged from top to bottom or bottom to top, forming a reasonable fabric transmission path, ensuring the uniformity and consistency of the fabric during dyeing and cooling processes, and improving cooling efficiency. The first drive unit includes three drive wheels, respectively arranged between different support pillars, used to drive the fabric to move in different areas of the equipment. The second drive unit is connected to the third support pillar 141, the fourth support pillar 142, and the cooling module. Specifically, the second pulley 220 is adjacent to and higher than the first drive wheel 411. Under the action of the first drive wheel 411, the knitted fabric can enter the cooling module smoothly. The third pulley 230 is adjacent to and horizontally arranged with the second drive wheel 412, used to stretch the knitted fabric in the cooling module. The fourth pulley 240 is located at the outlet of the cooling module, used to further stretch the rotated knitted fabric.

[0035] This embodiment provides additional driving force for the operation of the knitted fabric through the first driving unit, ensuring the stability and controllability of the knitted fabric during the cooling process.

[0036] Those skilled in the art will understand that the support components, guide module, and drive unit all adopt a modular design for easy disassembly and installation. The position and height of the pulleys and drive wheels can be adjusted according to actual needs to accommodate knitted fabrics of different specifications and thicknesses.

[0037] The cooling module is provided with a first roller 310, a second roller 320, a third roller 330, a fourth roller 340, a first connecting assembly 350, a second connecting assembly 360, a third connecting assembly, and a fourth connecting assembly 380. The second drive unit is provided with a fourth drive wheel 421, a fifth drive wheel 422, a sixth drive wheel 423, and a seventh drive wheel 424. The first roller 310, the second roller 320, the third roller 330, and the fourth roller 340 are arranged from top to bottom between the third support column 141 and the fourth support column 142. The fourth drive wheel 421 passes through the first connecting assembly 350 and the first roller 310. The fifth drive wheel 422 passes through the second connecting assembly 360 and the second roller 320. The sixth drive wheel 423 passes through the third connecting assembly 370 and the third roller 330. The seventh drive wheel 424 passes through the fourth connecting assembly 380 and the fourth roller 340.

[0038] It should be noted that the first roller 310, the second roller 320, the third roller 330, and the fourth roller 340 are arranged sequentially from top to bottom between the third support column 141 and the fourth support column 142, ensuring that the knitted fabric can pass through each roller in sequence for gradual cooling. The first connecting component 350, the second connecting component 360, the third connecting component 370, and the fourth connecting component 380 are respectively connected to each roller for support and transmission. The fourth drive wheel 421, the fifth drive wheel 422, the sixth drive wheel 423, and the seventh drive wheel 424 pass through each connecting component and roller, ensuring that each roller can rotate independently and stably, thereby achieving uniform cooling of the fabric. The second drive unit drives each drive wheel to rotate via a motor or other power source, which in turn drives the rollers to rotate. By setting up multiple rollers and corresponding connecting components and drive wheels, the knitted fabric is gradually cooled, improving the cooling efficiency and ensuring that the knitted fabric can reach the required cooling temperature in a short time. In addition, each roller can rotate independently and stably, so that the fabric can be heated and cooled evenly during the cooling process, avoiding local overheating or undercooling of the knitted fabric and improving the cooling uniformity of the knitted fabric.

[0039] It should be noted that the first roller 310, the second roller 320, the third roller 330 and the fourth roller 340 are all driven by variable frequency motor chains, and the first drive wheel 411 to the seventh drive wheel 424 are individually controlled by variable frequency.

[0040] The first connecting component 350 and the third connecting component 370 are disposed on one side of the third pillar 141 and the fifth pillar 151, and the second connecting component 360 and the fourth connecting component 380 are disposed on the other side of the third pillar 141 and the fifth pillar 151, wherein one side of the third pillar 141 and the fifth pillar 151 is the opposite side of the other side of the third pillar 141 and the fifth pillar 151.

[0041] It should be noted that this symmetrical distribution helps to balance the structural forces on the equipment. By setting connecting components on both sides of the fifth support column 151 and the sixth support column 152, the first roller 310, the second roller 320, the third roller 330 and the fourth roller 340 can better withstand the tension of the knitted fabric, the pressure of the rollers and other external forces during operation, reducing structural deformation or shaking caused by uneven stress, thereby improving the stability and reliability of the entire equipment.

[0042] Furthermore, the first connecting component 350, the second connecting component 360, the third connecting component 370, and the fourth connecting component 380 guide and support the fabric transport path. The multiple connecting components symmetrically arranged on both sides can ensure that the knitted fabric remains in the correct position during transport, preventing the knitted fabric from shifting, twisting, or wrinkling due to uneven force or guidance on one side, ensuring that the fabric is transported smoothly and stably in the cooling equipment, and improving the cooling efficiency of the knitted fabric.

[0043] Those skilled in the art will understand that the multiple connecting components in this embodiment can be operated from both sides, facilitating the alignment and connection of each roller and drive wheel, thereby reducing the installation difficulty and time of the cooling equipment. Simultaneously, during equipment maintenance, the connecting components on both sides are easily accessible, allowing maintenance personnel to conveniently inspect, maintain, and repair the connecting parts, reducing maintenance costs and difficulty.

[0044] The support frame module is also provided with a first extrusion cylinder 160 and a second extrusion cylinder 170. The first extrusion cylinder 160 is located at the lower part of the first crossbeam 101 and the third crossbeam, and the second extrusion cylinder 170 is located at the upper part of the second crossbeam 102 and the fourth crossbeam.

[0045] It should be noted that the first extrusion cylinder 160 is located below the first crossbeam 101 and the third crossbeam, while the second extrusion cylinder 170 is located above the second crossbeam 102 and the fourth crossbeam. This ensures that the knitted fabric is uniformly extruded by the opposing extrusion cylinders as it passes through the cooling equipment. Furthermore, the pressure exerted on the knitted fabric by the first extrusion cylinder 160 and the second extrusion cylinder 170 can be adjusted by regulating the pressure between the two cylinders. This ensures that the pressure on the knitted fabric is uniform in the width direction, avoiding excessive or insufficient extrusion in certain areas. This helps maintain the flatness and uniformity of the fabric. While extruding the fabric, the extrusion cylinders also assist in its transport. The extrusion of the fabric by the cylinders allows the knitted fabric to adhere more tightly to the cooling module, increasing the contact area and pressure between the fabric and the cooling module, thereby improving heat exchange efficiency and enhancing the cooling effect. In addition, extruding air from the fabric also helps improve the heat transfer efficiency between the cooling medium and the fabric, allowing the fabric to cool down more quickly. When the knitted fabric is squeezed, the friction between the extrusion cylinder and the fabric will drive the fabric forward. With the help of the fifth drive wheel 422, the feeding guide unit 120 and the third drive wheel 413, the knitted fabric is sent out of the cooling equipment.

[0046] A first gap is provided between the first extrusion cylinder 160 and the first crossbeam 101 and the third crossbeam, and a second gap is provided between the second extrusion cylinder 170 and the second crossbeam and the fourth crossbeam.

[0047] It should be noted that the first and second gaps provide a certain amount of space for the extrusion cylinders to move, acting as a buffer. When the knitted fabric encounters significant resistance or uneven thickness during extrusion, the extrusion cylinders can move appropriately within the gap range to prevent damage to the fabric or excessive pressure on the equipment due to over-extrusion, thus protecting both the knitted fabric and the equipment. Furthermore, since the thickness of knitted fabrics may vary, the gaps allow the first and second extrusion cylinders 160 and 170 to automatically adjust their positions according to the actual thickness of the fabric. For thicker knitted fabrics, the extrusion cylinders can move towards the gaps to provide sufficient extrusion space, ensuring effective extrusion and transfer of knitted fabrics of varying thicknesses, thus improving the adaptability and versatility of the equipment.

[0048] Secondly, this utility model embodiment also provides a fabric cooling machine, including the cold pad-batch dyeing and cooling equipment for knitted fabrics as described in the first aspect embodiment above.
