Description

Technical Field

[0001] The invention relates to the technical field of knitted fabric drying, in particular to a drying device for post-finishing of high-Cro value heat-comfortable warm knitted fabrics. Background Art

[0002] The thermal insulation principle of high-Kro value thermal comfort knitted fabrics is mainly based on multiple mechanisms. On the one hand, through special fiber selection and weaving technology, a large number of tiny air chambers are formed. Air is a poor conductor of heat. These air chambers can prevent the conduction and convection of heat, thereby playing a warming role. On the other hand, some fabrics use moisture-absorbing and heat-generating fibers, which can absorb moisture emitted by the human body and convert it into heat, further improving the warming effect. In the production process of knitted thermal fabrics, post-finishing is required. After completing the post-finishing process, the fabric needs to be dried, which requires the use of drying equipment.

[0003] When using traditional drying equipment, the fabrics are often passed through multiple support rollers into a relatively closed chamber, and high-temperature air is introduced into the chamber to dry the fabrics under the action of the hot air. However, when traditional equipment passes the whole bundle of fabrics through the support rollers, the fabrics need to be manually wrapped around the multiple support rollers. During this process, workers need to manually pull the fabrics. Since the drying chamber is in a relatively closed space, the equipment casing needs to be opened to wrap the fabrics, which is more laborious to operate. Summary of the invention

As the temperature of the inner cavity of the drying box 1 increases, the cloth 15 passes through the outer walls of the upper support roller 7 and the lower support roller 8 respectively, thereby achieving drying of the cloth 15.

[0036] In a preferred embodiment, there are four mounting plates 601 , and two mounting plates 601 form a group. The two groups of mounting plates 601 are respectively mounted on the outer walls of the U-shaped plates 501 on both sides.

[0037] In the above structure, a mounting plate 601 is arranged on the outer wall of the U-shaped plate 501, and a U-shaped plate 501 and a 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-tensioning wheel 605, the outer wall of the cloth 15 is clamped and fixed respectively.

[0038] In a preferred embodiment, the outer wall of the sprocket 10 is meshed with the inner wall of the chain 11 , and the power output shaft of the drive motor 12 is connected to the outer wall of the upper support roller 7 .

[0039] In the above structure, by means of a driving motor 12 arranged on the outer wall of the drying box 1, and a sprocket 10 and a chain 11 arranged on the outer wall of the upper support roller 7, the upper support roller 7 and the lower support roller 8 can be driven under the action of the driving motor 12, so that the upper support roller 7 and the lower support roller 8 can play an auxiliary driving role for the cloth 15 during the rotation process, so that the cloth 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.

[0040] Working principle: During the use of the above-mentioned equipment, when drying the cloth 15, the cloth 15 needs to be firstly passed into the inner cavity of the drying box 1, and respectively pass over the outer walls of the upper support roller 7 and the lower support roller 8, and by placing one end of the cloth 15 into the inner cavity of the U-shaped plate 501, the second drive motor 502 is started at this time, and the two-way screw 503 is driven to rotate under the action of the second drive 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 are respectively moved to the middle of the two-way screw 503, thereby realizing the driving of the auxiliary plate 507 and the connecting plate 508, so that The clamping plate 509 is attached to the outer wall of the cloth 15, and the U-shaped plates 501 on both sides are used to fix one end of the cloth 15, and then the No. 1 driving motor 406 is started. Under the action of the No. 1 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, so that the moving frame 403 moves along the outer wall of the fixed rail 401 as a whole. During the movement of the moving frame 403, the outer wall of the cloth 15 is pulled to move, so that the cloth 15 bypasses the outer walls of the upper support roller 7 and the lower support roller 8 respectively, and the surrounding installation of the cloth 15 is realized. Then, the drying air can be supplied to the drying air through the side air inlet bin 13 and the top air inlet bin 14. High-temperature air is supplied into the inner cavity of the drying box 1 to dry the cloth 15. After the surrounding installation of the cloth 15 is completed, the clamping plate 509 is detached from the outer wall of the cloth 15, and the cloth 15 is continuously pulled outward through one end of the inner cavity of the drying box 1 to achieve continuous drying of the cloth 15. During the continuous release of the cloth 15 at the end, the outer wall of the entire section of the cloth 15 cannot be kept taut due to the loss of tension at the end of the cloth 15, which will cause wrinkles in the cloth 15 when it enters the inner cavity of the drying box 1, thereby affecting the drying of the cloth 15. Therefore, after the movable frame 403 completes the traction installation of the cloth 15, the movable frame 403 is returned to the movable frame 403 again. The cloth 15 is moved to the initial end of the fixed rail 401, which corresponds to the feed port of the drying box 1. After returning the movable frame 403, the electric push rod 606 is adjusted to drive the movable shaft 604 downward under the action of the electric push rod 606. The movable shaft 604 moves downward along the inner wall of the slide groove 603, so that the outer wall of the pre-tightening wheel 605 acts on the outer wall of the cloth 15. At this time, one end of the cloth 15 discharged after drying is in a pulled state, and the other end is in a compressed state under the action of the pre-tightening wheel 605, ensuring that the outer wall of the cloth 15 entering the inner cavity of the drying box 1 remains in a taut state, avoiding wrinkles on the outer wall of the cloth 15, thereby better drying the outer wall of the cloth 15.
