Description

Technical Field

[0001] This utility model relates to the field of garment processing technology, and in particular to a washing and dyeing machine. Background Technology

[0002] In denim garment manufacturing, regular washing and light enzyme washing are two commonly used post-treatment methods to give denim garments a unique style and feel. However, these processes often result in color fading. This is because during the dyeing process, the dye's bond with the fibers is insufficient, causing the dye to easily detach from the fibers during subsequent washing, leading to uneven coloring and fading. This not only affects the overall appearance of the garment but also reduces its quality. Utility Model Content

[0003] The main purpose of this invention is to propose a washing and dyeing machine that aims to solve the problem of color fading in existing denim garments during subsequent washing.

[0004] To achieve the above objectives, the present invention provides a washing and dyeing machine, which includes:

[0005] frame;

[0006] The outer cylinder is mounted on the frame;

[0007] A color-fixing cylinder, rotatably disposed inside the outer cylinder, is filled with a color-fixing solution for soaking and fixing the denim garment. The cylinder wall is provided with multiple drainage holes.

[0008] The spraying device includes a nozzle installed inside the color-fixing cylinder. While the color-fixing cylinder rotates, the nozzle sprays the color-fixing liquid into the interior of the color-fixing cylinder to perform secondary color-fixing on the denim garment that has completed soaking and color-fixing.

[0009] In one embodiment, the spraying device includes a spray box and a plurality of nozzles spaced apart on the spray box. The spray box is installed at the end of the color-fixing cylinder, and the spraying direction of the nozzles is towards the interior of the color-fixing cylinder and communicates with the spray box.

[0010] In one embodiment, the spraying device further includes a storage tank located outside the outer cylinder and communicating with the spray box, the storage tank being used to store the fixing liquid.

[0011] In one embodiment, the spraying device further includes a metering switch and a connecting pipe, the connecting pipe connecting the spray box and the liquid storage tank, the metering switch being installed on the connecting pipe and used to adjust the liquid flow rate inside the connecting pipe.

[0012] In one embodiment, the washing and dyeing machine further includes a temperature and pressure integrated sensor, which is disposed on the wall of the color-fixing cylinder and is used to detect the dyeing temperature and dyeing pressure inside the color-fixing cylinder in real time.

[0013] In one embodiment, the washing and dyeing machine further includes a stop net disposed inside the color-fixing cylinder and spaced apart from the spray nozzle to prevent the denim garment from contacting the spray nozzle.

[0014] In one embodiment, the interior of the color-fixing cylinder forms a cavity, and a partition is provided in the cavity to divide the cavity into a plurality of independent sub-cavities, and each sub-cavity is provided with at least one of the spray nozzles.

[0015] In one embodiment, the color-fixing cartridge includes:

[0016] The cylinder frame is rotatably disposed inside the outer cylinder; and

[0017] Multiple cylinders are installed on the periphery of the cylinder frame in an openable and closable manner. The multiple cylinders are arranged sequentially to jointly enclose and form the cavity, and the drain hole is provided on the cylinder.

[0018] In one embodiment, the partition is arranged in a cross or X shape.

[0019] In one embodiment, the washing and dyeing machine further includes a recycling tank located below the outer cylinder and communicating with the interior of the outer cylinder to collect the liquid discharged from the drain hole on the color-fixing cylinder.

[0033] Denim garments are prone to color fading during regular washing and light enzyme washing processes. This is because the dye does not bind sufficiently to the fibers during the dyeing process, causing the dye to easily detach from the fibers during subsequent washing, resulting in uneven color and fading. This phenomenon not only affects the overall appearance of the garment but also reduces the quality of the product.

[0034] This utility model proposes a washing and dyeing machine.

[0035] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the washing and dyeing machine 100 includes:

[0036] Rack 1;

[0037] Outer cylinder 2 is mounted on frame 1;

[0038] A color-fixing cylinder 3 is rotatably disposed inside the outer cylinder 2. The color-fixing cylinder 3 is filled with a color-fixing solution to soak and fix the denim garment. The cylinder wall of the color-fixing cylinder 3 is provided with multiple drainage holes 321.

[0039] The spraying device 4 includes a nozzle 41 installed inside the color-fixing cylinder 3. While the color-fixing cylinder 3 rotates, the nozzle 41 sprays color-fixing liquid toward the inside of the color-fixing cylinder 3 to perform secondary color-fixing on the denim garment that has completed soaking and color-fixing.

[0040] The technical solution of this utility model involves placing denim garments inside a color-fixing cylinder 3 and filling the cylinder 3 with a color-fixing liquid. The amount of color-fixing liquid is sufficient to completely soak all parts of the denim garment, ensuring that every part of the garment comes into contact with the liquid. The denim garments are left to soak in the cylinder 3 for a period of time to complete the first color-fixing process. The color-fixing liquid is then drained through the drain hole 321 and subjected to a second color-fixing process via a spray device 4. During the rapid rotation of the color-fixing cylinder 3, the denim garments tumble continuously inside. At this time, the nozzles 41 of the spray device 4 continuously spray the color-fixing liquid onto the denim garments. The rotation of the cylinder 3 ensures that the color-fixing agent absorbed by the soaking denim garments is fully absorbed, completing the second color-fixing process. This effectively enhances the uniformity of color-fixing and prevents fading during subsequent washing processes. Through the initial soaking and color fixing in the color fixing cylinder 3 and the secondary spraying and color fixing in the spraying device 4, the color fixing effect of denim garments can be well achieved. In particular, it can effectively preserve the original luster of denim fabrics and prevent the finished products from staining each other when washed with other colored clothes. There is no need to worry about staining other clothes, making it convenient for users to wash and care for them.

[0041] Specifically, the structure of the nozzle 41 is not specifically limited; for example, it can be a shower head with multiple spray holes, as long as it can spray liquid. The soaking and color-fixing time of the denim garments in the color-fixing tank 3 is not specifically limited; for example, it can be 30 minutes, 40 minutes, or even more than an hour, depending on the quantity and material of the denim garments. During the first color-fixing process, the amount of color-fixing liquid is not specifically limited, as long as it completely submerges all the denim garments. Furthermore, the type and concentration of the color-fixing agent dissolved in the color-fixing liquid are not specifically limited; for example, it can be a polyurethane-based color-fixing agent, an organosilicon-based color-fixing agent, or an epoxy resin-based color-fixing agent, etc., depending on the material of the denim garments. During the first color-fixing, the prepared color-fixing liquid can be added directly to the color-fixing tank 3, or water can be added first, followed by the color-fixing agent. Similarly, the rotation time of the color-fixing tank 3 during the second color-fixing process is not specifically limited; for example, it can be 30 minutes, 40 minutes, or even more than an hour. It should be noted that the wall of the color-fixing cylinder 3 is provided with multiple drainage holes 321 to facilitate the rapid discharge of the color-fixing liquid.

[0042] In the embodiments of this utility model, please refer to Figure 3The spraying device 4 includes a spray box 42 and multiple nozzles 41 spaced apart on the spray box 42. The spray box 42 is installed at the end of the fixing cylinder 3, and the spray direction of the nozzles 41 faces the inside of the fixing cylinder 3 and is connected to the spray box 42. The spray box 42 can be a rectangular or circular container, and a fluid channel is provided inside the spray box 42 to deliver the fixing liquid to each nozzle 41. In addition, the spray box 42 is fixed to the end of the fixing cylinder 3 by bolts or clips to ensure its stability and sealing. For example, one end of the spray box 42 is provided with a flange, which is connected to the open flange of the fixing cylinder 3 and fastened with bolts. It should be noted that the spray box 42 is connected to an external fixing liquid supply system through a pipeline, and a flow control and pressure regulating device can be installed on the pipeline to adjust the spray force of the nozzles 41 and the flow rate of the fixing agent.

[0043] In the embodiments of this utility model, please refer to Figure 1 The spraying device 4 also includes a storage tank 43, which is located outside the outer cylinder 2 and communicates with the spray box 42. The storage tank 43 is used to store the fixing solution. The storage tank 43 can be cylindrical or three-dimensional, and can be made of corrosion-resistant materials such as stainless steel or plastic. Optionally, the tank can also be equipped with an inlet, an outlet, and a level gauge to indicate the remaining liquid level inside the tank in real time. Of course, the storage tank 43 can also be connected to the outer cylinder 2, so that the fixing solution discharged from the fixing cylinder 3 during one fixing process reaches the outer cylinder 2 and is then transferred from the outer cylinder 2 to the inlet on the storage tank 43.

[0044] In the embodiments of this utility model, please refer to Figure 3 The spray device 4 also includes a metering switch 44 and a connecting pipe 45. The connecting pipe 45 connects the spray box 42 and the liquid storage tank 43. The metering switch 44 is installed on the connecting pipe 45 and is used to regulate the liquid flow rate inside the connecting pipe 45. The metering switch 44 is a device for regulating fluid flow rate and can be a solenoid valve or a pneumatic valve. For example, the metering switch 44 can be an electromagnetic flow regulating valve, which receives a control signal to adjust the valve opening, thereby controlling the flow rate of the fixing liquid in the connecting pipe 45, and thus regulating the amount of fixing liquid sprayed from each nozzle 41.

[0045] In the embodiments of this utility model, please refer to Figure 4The dyeing machine 100 also includes a temperature and pressure integrated sensor 5, which is located on the wall of the color-fixing cylinder 3 and is used to detect the dyeing temperature and pressure inside the color-fixing cylinder 3 in real time. The temperature and pressure integrated sensor 5 can be semiconductor-based (using a silicon piezoresistive pressure sensor and a silicon temperature sensor integrated), ceramic-based (using a thick film or thin film to fabricate pressure and temperature sensitive elements on a ceramic substrate), or electromechanical (combining and encapsulating a traditional pressure sensor and temperature sensor). This way, only one mounting point is needed on the color-fixing cylinder 3, for example, fixed by threads or a flange in the middle of the cylinder wall, to more accurately reflect the temperature and pressure conditions inside the cylinder. Real-time detection of the temperature and pressure inside the color-fixing cylinder 3 helps improve the uniformity and effect of color fixing, thus improving the quality of the final product.

[0046] In the embodiments of this utility model, please refer to Figure 2 The dyeing machine 100 also includes a baffle net 6, which is located inside the color-fixing cylinder 3 and spaced apart from the spray head 41 to prevent denim garments from contacting the spray head 41. The baffle net 6 can be installed inside the color-fixing cylinder 3 using a fixed bracket. For example, the bracket can be fixed to the cylinder wall with screws and can be moved up and down to adjust the position of the baffle net 6 inside the color-fixing cylinder 3. The mesh size of the baffle net 6 should be large enough to effectively block the denim garments without creating excessive resistance to the spraying of the color-fixing liquid. For example, the mesh diameter can be 5 mm, and the distance between the baffle net 6 and the spray head 41 can be 20 cm, thus not affecting the spraying effect while effectively blocking the denim garments. The baffle net 6 can be made of corrosion-resistant, high-temperature-resistant metal materials or stainless steel.

[0047] In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The interior of the color-fixing cylinder 3 forms a cavity, and a partition 33 is provided inside the cavity to divide the cavity into multiple independent sub-cavities, with at least one nozzle 41 in each sub-cavity. The partition 33 can be made of corrosion-resistant stainless steel or other metal composite materials and is fixed inside the color-fixing cylinder 3 to form multiple sub-cavities. For example, the partition 33 can be detachably fixed by snap-fit ​​or screw connection, so as to adjust the number and size of the sub-cavities according to different color-fixing requirements. By setting the partition 33 to divide the internal cavity of the color-fixing cylinder 3 into multiple sub-cavities, the amount of denim garments in each sub-cavity is relatively fixed, so that the nozzle 41 can perform color-fixing treatment on the denim garments more evenly and reduce the uneven color-fixing caused by the stacking of denim garments. In this embodiment, the shape of the partition 33 is not specifically limited and can be designed as needed. The nozzle 41 can be installed at the top center of the sub-cavity and spray downward at a 45-degree angle to ensure that the color-fixing liquid can evenly cover the denim garment.

[0048] In the embodiments of this utility model, please refer to Figure 4The color-fixing cylinder 3 includes:

[0049] The tube frame 31 is rotatably disposed inside the outer tube 2; and

[0050] Multiple cylinders 32 are installed on the periphery of the cylinder frame 31 in an openable manner. The multiple cylinders 32 are arranged sequentially to form a cavity together, and a drain hole 321 is provided on the cylinder 32.

[0051] Specifically, the frame 31 is the supporting structure for the color-fixing cylinder 3. The frame 31 can consist of a central shaft and multiple support arms, with bearings installed on the support arms to allow the frame 31 to rotate smoothly. The cylinder body 32 is an openable and closable unit, installed around the periphery of the frame 31 and connected to the frame 31 via hinges or other rotating mechanisms, and can be opened outwards. For example, the cylinder body 32 can be semi-circular, and multiple cylinder bodies 32 can be sequentially spliced ​​together to form a complete circular cavity. Optionally, each cylinder body 32 can be equipped with an individual cylinder or electric motor, and automatic opening and closing can be achieved through button control. Furthermore, multiple drain holes 321 are spaced apart on each cylinder body 32, and can be circular holes or triangular holes, etc.

[0052] In the embodiments of this utility model, please refer to Figure 4 and Figure 5 The partitions 33 are arranged in a cross or X shape, meaning that each sub-cavity has a roughly the same shape and volume, ensuring that the denim garment has almost the same capacity within each sub-cavity, thus maintaining the balance of the color-fixing cylinder 3 during rotation. The partitions 33 can be two mutually perpendicular metal plates forming a cross or X-shaped intersecting structure, and can be installed inside the color-fixing cylinder 3 by screws, welding, or clips, ensuring the stability and durability of the partitions 33. For example, the two ends of the partitions 33 can be designed as slot structures, inserting into the fixing grooves on the inner wall of the color-fixing cylinder 3.

[0053] In the embodiments of this utility model, please refer to Figure 1 The dyeing machine 100 also includes a recovery tank 7, located below the outer cylinder 2 and communicating with its interior, to collect the liquid discharged from the drain hole 321 on the fixing cylinder 3. The recovery tank 7 can be a container with a sloping bottom, located directly below the fixing cylinder 3. Optionally, a filter device can be installed inside the recovery tank 7 to separate denim fibers and other impurities from the fixing solution. For example, a screen filter can be installed to intercept larger particles. Furthermore, the recovery tank 7 can also be equipped with a pumping system to re-transport the collected fixing solution to the spray device 4 or the fixing cylinder 3. For example, a water pump can be installed to pump the fixing solution to the storage tank 43.

[0054] 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.
