Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing equipment, and more specifically, to a washing device for knitted fabrics. Background Technology

[0002] In the knitwear production process, washing is a key step that determines the final feel, appearance and quality of the product. Its core purpose is to remove impurities such as oil, sizing and loose dye left over from the knitwear weaving process, and to adjust the fluffiness, elasticity and softness of the fabric fibers through physical and chemical actions, laying the foundation for subsequent shaping, printing and other processes. As the core physical action in the washing process, rubbing directly affects the washing efficiency and the fabric treatment effect. However, existing technologies still have the following problems: In industrial production, drum washing machines are mostly used. The washing is achieved by rotating the drum and causing the fabric to tumble and rub against the washing liquid. However, this "indiscriminate" friction method has obvious defects: On the one hand, for knitted products with a loose structure (such as thin cotton sweaters), it is easy to cause the fabric to stretch and deform, and the loops to shift. Utility Model Content

[0003] One objective of this invention is to provide a new technical solution for a washing device for knitted fabrics.

[0004] According to a first aspect of this utility model, a washing device for knitted fabrics is provided, comprising a frame, a washing tank inside the frame, a plurality of guide rollers inside the washing tank, and a washing device disposed between the plurality of guide rollers for washing knitted fabrics. A water pump is disposed on one side of the frame, and the water pump draws water into the washing tank through a water pipe. A fabric inlet support is disposed at one end of the frame, and a fabric outlet support is disposed at the other end of the frame. The fabric inlet support and the fabric outlet support are used for feeding and discharging fabric. The fabric outlet support is connected to a drying box for drying knitted fabrics.

[0005] Optionally, the scrubbing device includes an active roller and a passive roller, the surfaces of which are wavy, and one end of which extends to the outside of the washing tank and is provided with a gear. One end of the active roller is connected to a first drive motor, which is used to drive the active roller to rotate.

[0006] Optionally, the fabric feeding bracket is also provided with a fabric guide roller, which is used to guide the direction of the fabric during feeding.

[0007] Optionally, the fabric outlet support is provided with a bearing seat, and a squeezing shaft is installed between the bearing seats. The squeezing shaft is used to squeeze out the moisture from the fabric. There are two squeezing shafts, one of which is connected to a second drive motor at one end. The second drive motor is mounted on a mounting base on one side of the fabric outlet support and is used to drive the squeezing shaft to rotate.

[0008] Optionally, a heat flow box is installed at both the top and bottom of the drying oven. A heat pipe is connected between the heat flow box and the drying oven. The heat flow box inputs heat flow into the drying oven through the heat pipe. One end of the heat pipe extends into the drying oven and is connected to a fixing plate. A perforated plate is provided in the fixing plate for the uniform passage of hot air.

[0009] According to one embodiment of this disclosure, a knitted fabric washing device guides the fabric direction, controls tension, and assists in smoothing by using a guide roller, thereby avoiding problems such as fabric stretching and deformation, loop displacement, and fabric pilling. The surfaces of both parts of the washing device are smooth surfaces with wavy undulations, and the design of the passive roller moving in the opposite direction to the active roller allows for immersion and rolling of the fabric, making the fabric fibers fluffy and helping to remove dirt.

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0015] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0016] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0017] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0018] like Figure 1-4 As shown, a knitted fabric washing device includes a frame 1. Inside the frame 1 is a rectangular washing tank 2. Within the washing tank 2, several guide rollers 3 are arranged parallel to each other along the length of the tank. These guide rollers 3 have smooth surfaces to ensure smooth movement of the knitted fabric during washing. A scrubbing device 4 is installed between adjacent guide rollers 3, generating a scrubbing action through mechanical movement. A water pump 5 is fixedly installed on the right side of the frame 1. This water pump 5 is driven by an electric motor, with its inlet connected to an external water source and its outlet connected to the washing tank 2 via a water pipe, continuously pumping clean water into the washing tank 2. A fabric inlet support 8 is located at the front end of the frame 1, and a fabric outlet support 9 is installed at the rear end. The fabric outlet support 9 is connected to a rectangular drying chamber 13, which rapidly dries the washed knitted fabric, ensuring the product achieves the desired drying effect.

[0019] like Figures 1 to 4 As shown, the scrubbing device 4 includes an active scrubbing roller and a passive scrubbing roller. The surfaces of the active scrubbing roller and the passive scrubbing roller are set in a wave shape. One end of the active scrubbing roller and the passive scrubbing roller extends to the outside of the washing tank 2 and is provided with a gear 6. One end of the active scrubbing roller is connected to a first drive motor 7, which is used to drive the active scrubbing roller to rotate. Furthermore, the washing device 4 includes an active roller and a passive roller. The surfaces of the active roller and the passive roller are designed with a wave-like structure. This unique surface texture can significantly enhance the kneading effect on the material. In terms of equipment layout, one end of the active roller and the passive roller extends to the outer side of the washing tank 2, and a meshing gear 6 is installed at the extended end. The synchronous and coordinated operation of the two rollers is achieved through the transmission of the gear 6. The extended end of the active roller is also connected to a specially configured first drive motor 7. This motor, as the main power source, can accurately control and drive the active roller to rotate stably, thereby ensuring the continuity and efficiency of the entire extrusion and kneading process. like Figures 1 to 4 As shown, the fabric feeding bracket 8 is also equipped with a fabric guide roller 3, which is used to guide the direction of the fabric during feeding.

[0020] Furthermore, the fabric feeding bracket 8 is provided with a fabric guide roller 3, which is rotatably mounted on the fabric feeding bracket 8 via a bearing assembly, thereby effectively controlling the tension and direction of the fabric. like Figures 1 to 4 As shown, the fabric output bracket 9 is provided with a bearing seat 10, and a squeezing shaft 11 is installed between the bearing seats 10. The squeezing shaft 11 is used to squeeze out the moisture from the fabric. There are two squeezing shafts 11. One end of the squeezing shaft 11 is connected to a second drive motor 12. The second drive motor 12 is installed on a mounting base on one side of the fabric output bracket 9. The second drive motor 12 is used to drive the squeezing shaft 11 to rotate.

[0021] Furthermore, multiple bearing seats 10 are symmetrically arranged on the upper part of the fabric output bracket 9. A squeezing shaft 11 is installed between two adjacent bearing seats 10. One end of one squeezing shaft 11 is connected to the output shaft of the second drive motor 12 through a coupling. The second drive motor 12 drives the corresponding squeezing shaft 11 to rotate. Because the space between the two squeezing shafts 11 is narrow, the other squeezing shaft 11 can be driven to rotate relative to it when the fabric is output. This relative rotation design allows the squeezing shafts 11 to generate effective squeezing force. The main function of the squeezing shaft 11 is to fully squeeze out the residual moisture in the fabric through rotational squeezing and kneading actions, thereby improving the drying efficiency of subsequent processes. The entire squeezing device adopts a modular design, which is convenient for maintenance and replacement of parts, and ensures long-term stable operation of the equipment. like Figures 1 to 4 As shown, heat flow boxes 14 are installed at the top and bottom of the drying oven 13. A heat pipe 15 is connected between the heat flow box 14 and the drying oven 13. The heat flow box 14 inputs heat flow into the drying oven 13 through the heat pipe 15. One end of the heat pipe 15 extends into the drying oven 13 and is connected to a fixing plate 16. A perforated plate 17 is provided in the fixing plate 16 for the uniform passage of hot air.

[0022] Furthermore, heat flow boxes 14 are symmetrically installed at the top and bottom of the drying oven 13. The two sets of heat flow boxes 14 are located at the upper and lower ends of the drying oven 13, forming a bidirectional heating structure. The heat flow boxes 14 and the drying oven 13 are connected by heat pipes 15 to achieve continuous and stable heat flow, ensuring the heat supply during the drying process. One end of the heat pipe 15 extends into the interior of the drying oven 13 and is fixedly connected to a specially made fixing plate 16. A perforated plate 17 is embedded inside the fixing plate 16. The perforated plate 17 is densely covered with uniformly distributed micropores. These micropores allow high-temperature hot air to be evenly dispersed and passed through, thereby ensuring the uniform heat distribution inside the drying oven 13 and improving drying efficiency and quality.
