The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. The following describes an embodiment of the present invention based on its overall structure.

In view of the fabric hemming problem shown in fig. 1-2, the present disclosure provides a drying structure, as shown in fig. 3, comprising:

a plurality of layers of drying channels 1 for drying the object 2 to be dried;

each layer of drying channel 1 comprises a bearing mechanism for bearing an object 2 to be dried;

as shown in fig. 4, even number of groups of chain needle plates 5 are respectively disposed on the bearing mechanism in at least one layer of drying channel 1, wherein each layer of drying channel having the chain needle plate 5 is provided with two groups of chain needle plates 5, and one side of the chain needle plate 5 having the needle plate faces the object 2 to be dried, and the two side edges of the object 2 to be dried are respectively used for stretching and fixing, so that the object 2 to be dried maintains a flat state in the drying process.

In particular, in order to solve the problem that some fabrics are curled and cannot be effectively flattened during drying, the drying mechanism can be additionally arranged. Each of the carrying mechanisms may include a mesh belt or a pair of guide rails 4 arranged in parallel in the drying tunnel 1, and when the carrying mechanism is the guide rail 4, for example, a chain needle plate 5 may be arranged on the guide rails 4 on both sides of the first-layer drying tunnel. In the drying process, the two side edges of the object to be dried 2 are hung on one surface of the chain needle plate 5 with the needle plate for drying and shaping, and the edge curling of the object to be dried 2 can be effectively prevented by drying for a section of length. Fig. 5 is a top view of the guide rail, the chain needle plate 5 is installed on the guide rail on both sides and can slide on the guide rail 4, fig. 6 is a running direction of the object to be dried on the guide rail, the chain needle plate 5 can run with the object to be dried 2.

As an alternative embodiment, the guide rail 4 may be a horizontal guide rail as shown in fig. 7 or a vertical guide rail as shown in fig. 8: when the guide rail is a horizontal guide rail, as shown in fig. 7, the chain needle plate 5 is only arranged on the first layer drying channel; when the guide rail is a vertical guide rail, as shown in fig. 8, the upper and lower ends of the guide rail are provided with the chain needle plates 5, that is, the first layer drying channel and the second layer drying channel are respectively provided with two groups of chain needle plates. The needles on the chain needle plate 5 are hung on the two side edges of the object to be dried, so that the object to be dried is in a flat state. Because the edges of the two sides of the object to be dried 2 are tensioned, after the object to be dried is dried by hot air through the drying channel, the breadth of the object to be dried is flat, all parts are dried uniformly, the drying effect can be obviously improved, and the object to be dried is prevented from curling. Set up chain faller 5 according to different types of guide rail 4 in this embodiment, perpendicular guide rail can set up two-layer chain faller 5, as shown in fig. 9, because first layer stoving passageway and second floor stoving passageway all are equipped with chain faller 5, the fixed time of waiting to dry 2 both sides of article of chain faller to dry is longer, and the effect of tentering design is also better.

As an optional implementation manner, the drying structure may further include a needle-off automatic stop mechanism, which is disposed at the cloth feeding position of the guide rail 4 and used for detecting whether the object 2 to be dried is normally hung on the chain needle plate 5, and if the object cannot be normally inserted, the needle-off automatic stop mechanism controls the main machine to stop operating. For example, the needle-off automatic stop mechanism may adopt a photoelectric switch, as shown in fig. 5, when the object to be dried 2 enters the cloth feeding position 4A of the guide rail 4 of the drying structure, the object to be dried needs to be needled, that is, two side edges are fixed by the chain needle plate 5, if the object to be dried 2 cannot be needled normally at the cloth feeding position of the guide rail 4, the photoelectric switch detects that the host is stopped, and the operator can timely re-needle the object to be dried 2 which is out of stitches. The photoelectric switch is a short term photoelectric proximity switch, and detects the presence or absence of an object by turning on a circuit by a synchronous circuit by utilizing the shielding or reflection of the object to be detected on a light beam. The object is not limited to metal, and all objects that reflect light (or block light) can be detected. The photoelectric switch converts the input current into an optical signal on the transmitter to be emitted, and the receiver detects the target object according to the intensity or the existence of the received light.

When the object 2 to be dried passes through the needle-removing structure at the cloth outlet 4B of the guide rail 4 without needle removal, the object 2 to be dried touches the travel switch, so that the main machine stops running, and an operator can perform needle removal treatment in time. The travel switch realizes the connection or disconnection of a control circuit by using the contact of the travel switch to act by using the collision of a mechanical motion part, thereby achieving a certain control aim. Generally, such switches are used to limit the position or stroke of the movement of the machine, so that the moving machine can automatically stop, move in reverse, shift or automatically move back and forth according to a certain position or stroke.

As an optional implementation manner, each layer of drying channel 1 is provided with a plurality of air nozzles 6, which are uniformly distributed above and below the object to be dried 2, and air outlets of the air nozzles 6 face the object to be dried 2 for providing hot air. In the embodiment, the circulating fan is adopted to provide hot air, and the hot air is output to the objects to be dried through the plurality of air nozzles 6.
