Description

Technical Field

[0001] This application relates to the field of dryers, and more particularly to a dryer for woven cotton fabrics. Background Technology

[0002] In the research and development of low-energy gas-liquid separation dyeing technology for woven cotton fabrics, dynamic gas-liquid separation and low liquor ratio control are adopted to reduce the liquor ratio during the dyeing process of cotton fabrics and improve the utilization rate of dyes. In the post-processing of the fabric, the undyed floating dye on the woven cotton fabric is first washed away by a washing machine, then the color fastness of the fabric is improved by a color fixing device, and finally the fabric is dried by a dryer.

[0003] Currently, Chinese utility model patent CN222799509U discloses a fabric drying device, including a box with a fabric inlet and an outlet. Several guide rollers are installed inside the box, a heating element is located at the bottom of the box, and an expanding roller is installed inside the box, parallel to the guide rollers. Driving elements are located at both ends of the expanding roller inside the box, and a flattening element is located between the guide rollers inside the box. After the fabric enters the box, the heating element heats and dries the fabric. The fabric is wound around the guide rollers, expanded by the expanding rollers, and then flattened by the flattening element. During the drying process, the fabric is expanded and flattened, resulting in a smooth fabric with fewer wrinkles.

[0004] Because the box only has an inlet and an outlet for fabric, and there are guide rollers inside the box that the fabric needs to go around, the fabric feeding process is inconvenient and greatly affects work efficiency. Utility Model Content

[0005] In order to improve the efficiency of fabric feeding in the dryer, this application provides a dryer for woven cotton fabrics.

[0006] This application provides a dryer for woven cotton fabrics, which adopts the following technical solution: A dryer for woven cotton fabrics includes a box body, a cover plate, and a locking component. The box body has a fabric inlet and a fabric outlet on its two opposite side walls. The box body has an opening on one side along the width of the fabric to be dried. The cover plate is vertically arranged and is slidably connected to the box body in a direction close to or away from it. The cover plate is used to cover the opening of the box body. The locking component is used to prevent the cover plate from detaching from the box body. The box body is provided with a plurality of guide rollers and a heating assembly.

[0007] By adopting the above technical solution, by setting an opening along the width of the fabric in the box and using a sliding cover plate, the fabric can be directly fed around the guide rollers from the opening when the cover plate is opened, which greatly simplifies the feeding process and effectively improves work efficiency. At the same time, the cover plate can cover the opening of the box, and the locking part can prevent the cover plate from detaching from the box, preventing the heat inside the box from being lost through the opening during the drying process, ensuring the temperature inside the box is stable, and ensuring the drying effect of the heating component on the fabric. Several guide rollers can guide the fabric transmission path and work with the heating component to achieve effective drying of the fabric.

[0008] Optionally, a plurality of sliding rods are provided on the side wall of the cover plate facing the box body. The sliding rods are evenly distributed on the cover plate, and the length direction of the sliding rods is parallel to the direction from the cover plate to the box body. One end of the sliding rod is provided on the cover plate, and the sliding rod slides along the length direction of the sliding rod and is connected to the inner side wall of the box body.

[0009] By adopting the above technical solution, and through the sliding cooperation of several evenly distributed sliding rods with the chamber, the cover plate is subjected to more uniform force during the sliding process of approaching or moving away from the chamber. This can prevent the cover plate from shifting or tilting, ensuring that the cover plate accurately seals the opening of the chamber. At the same time, it reduces the wear of components during the sliding process and extends the service life of the equipment. Furthermore, the setting of the sliding rods further strengthens the connection between the cover plate and the chamber. Compared with the simple sliding of the cover plate, it can better bear the weight of the cover plate itself and the external forces that may be generated during the drying process, ensuring the stability of the overall structure of the equipment.

[0010] Optionally, the cover plate is provided with rollers that abut against the ground.

[0011] By adopting the above technical solution, the roller contacts the ground, converting the sliding friction between the cover plate and the ground into rolling friction, which greatly reduces the resistance when the cover plate slides.

[0012] Optionally, a handle is provided on the side of the cover plate opposite to the box body.

[0013] By adopting the above technical solution, when moving the cover plate, the operator can apply force by holding the handle, avoiding the inconvenience caused by the smooth surface of the cover plate or the lack of a suitable force application point. This makes the sliding operation of the cover plate more precise and efficient, and further improves the convenience of equipment operation.

[0014] Optionally, the locking component includes a locking rod, a locking frame, a locking block, and a locking screw. The length direction of the locking rod is parallel to the sliding direction of the cover plate. One end of the locking rod is disposed on the cover plate. The locking frame is disposed on the housing and through which the locking rod passes. The locking block is slidably connected to the locking frame along a direction perpendicular to the length direction of the locking rod. The length direction of the locking screw is parallel to the sliding direction of the locking block. The locking screw is rotatably connected to the locking frame. The locking block is threadedly connected to the locking screw. The locking rod has a locking groove for the locking block to engage.

[0015] By adopting the above technical solution, after the cover plate seals the box, rotating the locking screw can drive the locking block to slide and engage with the locking rod's locking groove, thus achieving a firm lock between the cover plate and the box, preventing the cover plate from loosening and causing heat loss during the drying process. To unlock, simply rotate the locking screw in the opposite direction to disengage the locking block from the locking groove. The operation is simple and quick, balancing locking reliability and ease of operation, ensuring a stable drying process without affecting equipment efficiency. At the same time, the length direction of the locking rod is parallel to the sliding direction of the cover plate, and the sliding direction of the locking block is perpendicular to the length direction of the locking rod. This structural design can precisely match the sliding action of the cover plate, ensuring that the locking component can accurately achieve the locking function when the cover plate slides to the sealing position, and the structure has strong adaptability.

[0016] Optionally, the locking slot is provided with a guide slope to facilitate the entry of the locking block.

[0017] By adopting the above technical solution, the guide slope can guide the locking block. Even if there is a slight positional deviation between the locking block and the locking groove, it can still slide smoothly into the locking groove through the guide slope, reducing the alignment adjustment time during the locking operation, improving the efficiency of the locking operation, and avoiding wear on the edge of the locking block or locking groove due to hard alignment.

[0018] Optionally, a sealing strip is provided on the side wall of the cover plate facing the box body, and a sealing groove is provided on the box body, the sealing strip being used to engage with the sealing groove of the box body.

[0019] By adopting the above technical solution, the gap between the cover plate and the box is filled by the cooperation of the sealing strip and the sealing groove, which further prevents heat from leaking from the opening inside the box, making the temperature inside the box more stable, improving the drying efficiency of the heating components, reducing energy waste, and at the same time preventing external dust and impurities from entering the box from the gaps and contaminating the fabric, thus ensuring the quality of the dried fabric.

[0020] Optionally, the length direction of the guide roller is parallel to the width direction of the fabric, and several guide rollers are distributed in a zigzag pattern along the conveying direction of the fabric. The guide rollers are rotatably connected to the housing. The heating component includes several heating tubes, which correspond to several guide rollers. The length direction of the heating tubes is parallel to the length direction of the guide rollers. The heating tubes are located on the side of the fabric away from the corresponding guide rollers and are housed inside the housing.

[0021] By adopting the above technical solution, the zigzag-shaped distribution of the guide rollers extends the transmission path and dwell time of the fabric within the box, allowing the fabric to make more full contact with the heating components. At the same time, the heating tubes correspond one-to-one with the guide rollers and are located on the side of the fabric away from the guide rollers, which can heat both sides of the fabric, avoiding uneven heating in certain areas and ensuring a consistent overall drying effect, thus improving drying quality and efficiency. Furthermore, the lengths of the guide rollers and heating tubes are parallel to the width of the fabric, completely covering the width of the fabric and ensuring that the fabric is effectively guided and heated in the width direction. This avoids problems such as insufficient drying at the edges of the fabric or transmission deviation due to insufficient component length, and adapts to the drying needs of woven cotton fabrics of different widths.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The box body has an opening on one side along the width of the fabric and is equipped with a sliding cover plate. When loading the fabric, the cover plate can be opened to complete the fabric wrapping from the opening. The handle on the cover plate provides a convenient point of force application, and the rollers convert sliding friction into rolling friction, reducing sliding resistance. The combination of these three features greatly simplifies the loading process and improves work efficiency. 2. The locking mechanism prevents the cover plate from detaching from the chamber, thus avoiding heat loss. The cover plate has a sealing strip on the side wall facing the chamber, and the chamber has a corresponding sealing groove. The sealing strip is snapped into the sealing groove to further fill the gaps and block heat leakage, which not only ensures the drying effect of the heating components, but also reduces energy consumption and improves energy efficiency. 3. The guide rollers are arranged in a zigzag pattern along the fabric conveying direction, extending the fabric's residence time inside the chamber and ensuring full contact with the heating components. The heating tubes correspond one-to-one with the guide rollers and are located on the side of the fabric away from the guide rollers, allowing for heating of both sides of the fabric, preventing uneven heating and ensuring drying quality. Simultaneously, the lengths of the guide rollers and heating tubes are parallel to the fabric width, enabling the covering of fabrics of varying widths and improving equipment adaptability.

The length direction of the guide rollers 13 is parallel to the width direction of the fabric. The guide rollers 13 are rotatably connected to the inner side wall of the box body 1. The heating assembly includes a plurality of heating tubes 14, which correspond to the plurality of guide rollers 13. The heating tubes 14 are located on the side of the fabric away from the corresponding guide roller 13 and are fixedly installed on the inner side wall of the box body 1.

[0029] Reference Figure 2 and Figure 3The cover plate 2 is used to seal the opening of the box body 1, and the locking element 3 is used to prevent the cover plate 2 from detaching from the box body 1. The cover plate 2 is vertically arranged, and four sliding rods 21 are provided on the side of the cover plate 2 facing the box body 1. The four sliding rods 21 are evenly distributed on the side wall of the cover plate 2. The length direction of the sliding rods 21 is parallel to the width direction of the fabric. One end of the sliding rod 21 is fixedly set on the cover plate 2. The sliding rod 21 slides along the width direction of the fabric and is connected to the inner side wall of the box body 1. Two rollers 22 are provided on the cover plate 2, and the two rollers 22 are distributed along the length direction of the box body 1. The axis of roller 22 is parallel to the length direction of roller 22. Roller 22 is rotatably connected to the lower end face of cover plate 2. Roller 22 is used to roll on the ground. Two handles 23 are fixedly installed on the side wall of cover plate 2 away from sliding rod 21. The two handles 23 are distributed along the length direction of box body 1. A sealing groove 15 is opened on the side wall of box body 1 facing cover plate 2. The sealing groove 15 extends along the width direction of box body 1. A sealing strip 24 is fixedly installed on the side wall of cover plate 2 facing box body 1. The sealing strip 24 is used to snap into the sealing groove 15 of box body 1.

[0030] Reference Figure 2 and Figure 3 Two locking components 3 are distributed on both sides of the cover plate 2 along the length direction of the box body 1. The locking component 3 includes a locking rod 31, a locking frame 32, a locking block 33, and a locking screw 34. The length direction of the locking rod 31 is parallel to the width direction of the box body 1. One end of the locking rod 31 is fixedly set on the cover plate 2. The locking frame 32 is fixedly set on the side wall of the box body 1. The opening of the locking frame 32 allows the locking rod 31 to pass through. The locking block 33 is vertically slidably connected to the locking frame 32. The locking screw 34 is vertically set and rotatably connected to the locking frame 32. The locking block 33 is threadedly connected to the tail of the locking screw 34. A snap-fit ​​groove 35 is opened on the side wall of the locking rod 31. A guide slope 36 is opened between the bottom of the snap-fit ​​groove 35 and the side wall of the snap-fit ​​groove 35 away from the cover plate 2.

[0031] The implementation principle of a woven cotton fabric dryer according to an embodiment of this application is as follows: First, force is applied by the handle 23 on the side of the cover plate 2 away from the box body 1. The roller 22 at the lower end of the cover plate 2, which abuts against the ground, is used to convert sliding friction into rolling friction. The cover plate 2 is pushed to slide along the length direction of the sliding rod 21, opening the opening of the box body 1 along the width direction of the fabric. The fabric is directly wrapped around the guide rollers 13, which are distributed in a zigzag pattern inside the box body 1, from the opening. After the feeding is completed, the cover plate 2 is pushed in the opposite direction to close the opening of the box body 1. At this time, the sealing strip 24 on the cover plate 2 is inserted into the sealing groove 15 of the box body 1.

[0032] Next, the locking component 3 is operated. The locking screw 34 on the locking frame 32 is rotated, which drives the locking block 33, which slides vertically, to move. This causes the locking block 33 to engage with the locking groove 35 of the locking rod 31 (the guide slope 36 of the locking groove 35 assists the locking block 33 to enter smoothly), preventing the cover plate 2 from detaching from the box 1. Subsequently, the fabric enters from the inlet 11 on one side of the box 1 and is transported along a zigzag path under the guidance of the guide roller 13. During the process, the heating tubes 14, which correspond one-to-one with the guide roller 13, heat both sides of the fabric. Finally, the dried fabric is sent out from the outlet 12 on the other side of the box 1, realizing convenient feeding and efficient drying of woven cotton fabrics.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
