Description

Technical Field

[0001] The present invention relates to the technical field of drying of knitted fabrics, and specifically to a drying device for post-treatment of high-Clo-value thermally comfortable and warm knitted fabrics. Background Art

[0002] The heat preservation principle of high-Clo-value thermally comfortable and warm knitted fabrics is mainly based on multiple mechanisms. On the one hand, through special fiber selection and knitting processes, a large number of tiny air chambers are formed. Air is a poor conductor of heat, and these air chambers can prevent heat conduction and convection, thus playing a heat preservation role. On the other hand, some fabrics use moisture-absorbing and heat-generating fibers, which can absorb the moisture emitted by the human body and convert it into heat, further enhancing the heat preservation effect. During the production process of knitted thermal fabrics, post-treatment is required. After the post-treatment process is completed, the fabric needs to be dried, and drying equipment is required.

[0003] When traditional drying equipment is in use, it often passes the fabric through multiple support rollers and enters a relatively enclosed chamber, and high-temperature air is introduced into the chamber to dry the fabric under the action of the hot air. However, when passing a whole bundle of fabric through the support rollers, the fabric needs to be manually wound around multiple support rollers one by one. During this process, workers need to manually pull the fabric. Since the drying chamber is in a relatively enclosed space, the equipment housing needs to be opened to wind the fabric, and the operation is rather laborious. Summary of the Invention

[0043] In a preferred embodiment: The pre-tightening assembly 6 includes a mounting plate 601. A connecting frame 602 is fixedly assembled on the outer wall of the mounting plate 601.

[0047] In a preferred embodiment: The outer wall shape of the fixed rail 401 matches the inner wall shape of the track groove 3. The outer wall of the fabric 15 is respectively rotatably connected to the outer walls of the upper support roller 7 and the lower support roller 8. The inner cavities of the top air inlet chamber 14 and the side air inlet chamber 13 are respectively communicated with the inner cavity of the drying box 1.

[0048] In the above structure, through the side air inlet chamber 13 and the top air inlet chamber 14 provided on the outside and the top of the drying box 1, hot air is introduced into the inner cavity of the drying box 1 through the side air inlet chamber 13 and the top air inlet chamber 14, so that the temperature in the inner cavity of the drying box 1 rises. As the temperature in the inner cavity of the drying box 1 rises, and the fabric 15 passes through the outer walls of the upper support roller 7 and the lower support roller 8 respectively, thereby realizing the drying of the fabric 15.

[0049] In a preferred embodiment: The number of the mounting plates 601 is four, and two mounting plates 601 form a group. The two groups of mounting plates 601 are respectively installed on the outer walls of the two side U-shaped plates 501.

[0050] In the above structure, the mounting plate 601 is arranged on the outer wall of the U-shaped plate 501, and the U-shaped plate 501 and the mounting plate 601 are arranged on the inner walls on both sides of the drying box 1. Under the action of the mounting plate 601 and the pre-tightening wheel 605, the outer wall of the fabric 15 is clamped and fixed respectively.

[0051] In a preferred embodiment: the outer wall of the sprocket 10 meshes with the inner wall of the chain 11, and the power output shaft of the driving motor 12 is connected to the outer wall of the upper support roller 7.

[0052] In the above structure, the driving motor 12 is arranged on the outer wall of the drying box 1, and the sprocket 10 and the chain 11 are arranged on the outer wall of the upper support roller 7. Under the action of the driving motor 12, the upper support roller 7 and the lower support roller 8 can be driven, so that the upper support roller 7 and the lower support roller 8 can play an auxiliary driving role in the process of rotation, so that the fabric 15 can pass through the inner cavity of the drying box 1 under the action of the upper support roller 7 and the lower support roller 8.

[0053] Working principle: During the use of the above-mentioned device, when drying the fabric 15, the fabric 15 needs to be first passed into the inner cavity of the drying box 1 and bypassed around the outer walls of the upper support roller 7 and the lower support roller 8 respectively. By placing one end of the fabric 15 into the inner cavity of the U-shaped plate 501, at this time, by starting the second driving motor 502, the rotation of the bidirectional screw 503 is driven under the action of the second driving motor 502, thereby realizing the driving of the first moving block 504 and the second moving block 505, so that the first moving block 504 and the second moving block 505 move towards the middle of the bidirectional screw 503 respectively, thereby realizing the driving of the auxiliary plate 507 and the connecting plate 508, and making the clamping plate 509 fit on the outer wall of the fabric 15. The two sides of the U-shaped plate 501 are respectively used to fix one end of the fabric 15. Subsequently, the first driving motor 406 is started. Under the action of the first driving motor 406, the driving wheel 405 is driven, so that the driving wheel 405 moves along the inner wall of the limiting groove 402, and the whole moving frame 403 moves along the outer wall of the fixed rail 401. During the movement of the moving frame 403, the outer wall of the fabric 15 is pulled to move, so that the fabric 15 bypasses the outer walls of the upper support roller 7 and the lower support roller 8 respectively. When the fabric 15 is installed in a loop, high-temperature air can be supplied into the inner cavity of the drying box 1 through the side air inlet chamber 13 and the top air inlet chamber 14 to realize the drying of the fabric 15. And after the loop installation of the fabric 15 is completed, the clamping plate 509 is separated from the outer wall of the fabric 15, and the end of the fabric 15 passing through the inner cavity of the drying box 1 is continuously pulled outwards to realize the continuous drying of the fabric 15. During the continuous release of the end fabric 15, since the end of the fabric 15 loses tension, the outer wall of the entire fabric 15 cannot maintain a taut state, which will cause the fabric 15 to wrinkle when entering the inner cavity of the drying box 1, thus affecting the drying of the fabric 15. Therefore, after the moving frame 403 completes the traction installation of the fabric 15, the moving frame 403 is returned to the initial end of the fixed rail 401 again, which corresponds to the feed inlet of the drying box 1. After the moving frame 403 is returned, by adjusting the electric push rod 606, the moving shaft 604 is driven downward under the action of the electric push rod 606, and the moving shaft 604 moves downward along the inner wall of the chute 603, so that the outer wall of the pre-tightening wheel 605 acts on the outer wall of the fabric 15. At this time, one end of the fabric 15 after drying and discharging is being pulled, and the other end is in a state of being pressed under the action of the pre-tightening wheel 605, ensuring that the outer wall of the fabric 15 entering the inner cavity of the drying box 1 remains taut, avoiding wrinkles on the outer wall of the fabric 15, and thus better drying the outer wall of the fabric 15.
