The equipment used for baking and forming is an oven, and the heating device in the oven is used to bake the passing electrode sheets. Currently, the heating device in the oven is mainly an infrared heating device, which generates radiant heat energy by energizing the infrared heating plate assembly to heat the electrode sheets and cause them to dry quickly.

[0003] The wires connected to the infrared heating device usually need to reserve a certain length to facilitate the extraction of the infrared heating device along the width direction of the oven. This part of the reserved wires needs to be fixed on the infrared heating device by a corresponding coiled wire structure to prevent them from falling under the radiation surface of the infrared heating device and causing melting. However, the existing coiled wire structure is complex and requires secondary wire fixing or locking by cooperating with other components, resulting in the need to unlock the wires first when the infrared heating device is extracted, with cumbersome operation and low efficiency. Moreover, there are also unexpected situations where the wires cannot be disconnected due to cooperation problems, and finally, wire cutting / rewiring operations have to be carried out.

[0048] Please refer to Figure 1 and Figure 2 , an embodiment of a wire coiling structure and an infrared heating device provided in the embodiments of this application includes:

[0049] Card line body 1.

[0050] The wire clamp body 1 is provided with a wire accommodating cavity penetrating both sides thereof, and the wire accommodating cavity is used to accommodate the wire 100 .

[0051] One end of the wire clamp body 1 is provided with two limiting parts 2 arranged opposite to each other, and a clamping port 21 for clamping the wire 100 into the wire accommodating cavity is formed between the two limiting parts 2; the wire clamp body 1 is elastic and / or at least one limiting part 2 is elastic, so that the opening and closing size of the clamping port 21 is elastically variable.

[0052] In summary, the coiled wire structure designed above has the following beneficial effects:

[0053] 1. It can realize fast wire winding, wire drawing / wire removal operations, without the need for secondary wire fixing or locking through other components, and there is no need to unlock again when disassembling. It is easy to operate, efficient, and there will be no problem of wire cutting / rewiring.

[0054] 2. It can firmly clamp the wire 100 to prevent the wire 100 from spreading and sliding under the radiation surface of the infrared heating device, thereby causing safety hazards.

[0055] The above is an embodiment of a coiled wire structure provided in the embodiment of the present application. The following is an embodiment of a coiled wire structure provided in the embodiment of the present application. For details, please refer to Figures 1 to 2 .

[0056] Based on the solution of the above embodiment 1:

[0057] Furthermore, if Figure 1 as well as Figure 2 As shown, the wire cavity is designed to be flat, so that the wires 100 can be neatly arranged in the wire cavity, which is convenient for wire extraction or removal.

[0058] Furthermore, the clamping side distance of the wire-containing cavity cross section is smaller than the circumferential diameter of the accommodated wire 100, so as to clamp the wire 100 and ensure that the wires 100 are neatly arranged to avoid the wires 100 being stacked and melted to cause safety hazards.

[0059] Furthermore, if Figure 2As shown, the wire clamping body 1 includes a clamping plate portion 11 and a connecting portion 12.

[0060] There are two clamping plate portions 11, which are arranged symmetrically at intervals. The distance between the two clamping plate portions 11 is the distance of the clamping side of the cross-section of the wire receiving cavity.

[0061] One end of the two clamping plate portions 11 is connected by the connecting portion 12, and a wire receiving cavity is formed between them and the connecting portion 12; a limiting portion 2 is respectively connected to the other end of each clamping plate portion 11.

[0062] The clamping plate portion 11 is a plate structure, while the connecting portion 12 is a convex folded ridge plate structure, which is arranged opposite to the opening. Those skilled in the art can make appropriate variation designs based on this without limitation.

[0063] Further, between the parts of the two limiting portions 2 that are closer to the wire receiving cavity than the bayonet 21, a first guiding port 22 communicating the wire receiving cavity with the bayonet 21 is formed; the first guiding port 22 gradually narrows along the direction extending out of the bayonet 21. The first guiding port 22 can play a guiding role to facilitate the wire 100 to be taken out from the position of the first guiding port 22 through the bayonet 21.

[0064] Between the parts of the two limiting portions 2 that are farther from the wire receiving cavity on the other side than the bayonet 21, a second guiding port 23 communicating the bayonet 21 with the external environment is formed; the second guiding port 23 gradually expands along the direction extending out of the bayonet 21; the second guiding port 23 also plays a guiding role to facilitate the wire 100 to be clamped into the bayonet 21 from the position of the second guiding port 23.

[0065] Further, taking the design of the first guiding port 22 and the second guiding port 23 as an example, the limiting portion 2 can be designed as a hinge structure, and the folding parts of the two limiting portions 2 are arranged facing each other, with a bayonet 21 formed between them. A first guiding port 22 is formed between the inclined surfaces of the two limiting portions 2 on one side of the bayonet 21, and a second guiding port 23 is formed between the inclined surfaces of the two limiting portions 2 on the other side of the bayonet 21.

[0066] Moreover, the limiting portion 2 and the wire clamping body 1 are integrally connected and designed. By designing the fiber cloth as a hinge structure, it can be formed by bending processing; the wire clamping body 1 and the limiting portion 2 can be integrally bent and formed to improve the convenience of processing.

[0067] Further, a fixing portion 3 is further included. The fixing portion 3 can be a plate structure;

[0068] An installation structure 31 is provided on the fixing portion 3. The installation structure 31 can be, for example, an installation hole, which is used to cooperate with fasteners such as fastening screws to realize the fixed installation of the wire winding structure.

[0069] The fixing part 3 is connected to the wire clamping main body 1 or to one end of a limiting part 2 that is far from the wire clamping main body 1. It is preferably designed to be connected to one end of a limiting part 2 that is far from the wire clamping main body 1, which is convenient for integral bending and forming and improves the convenience of processing.

[0070] As Figures 3 to 5 shown, the present application also discloses an infrared heating device, including a device body 200 and at least one wire 100.

[0071] The wire 100 is fixed on the surface of the device body 200 through a plurality of the above-designed wire coiling structures.

[0072] Furthermore, the device body 200 includes a device housing 201 and an operating component.

[0073] The operating component is installed inside the device housing 201. The operating component is a component used after being powered on, such as a thermocouple, a detection component, and an infrared heating plate, etc.; the device housing 201 includes a housing and a cover body. The cover body is detachably covered on the housing and forms an installation cavity for accommodating the operating component with the housing.

[0074] A terminal block 202 is also installed on the surface of the device housing 201. The terminal block 202 can specifically be installed on the surface of the housing or the cover body, and is preferably arranged on the same plane as the wire coiling structure.

[0075] The wire 100 is connected between the operating component and the terminal block 202.

[0076] Moreover, as Figure 5 shown, a fixing bracket 203 for fixing is also installed on the device housing 201.

[0077] As Figure 3 shown, specifically three wires 100 are provided on the device body 200, and each wire 100 is fixed on the surface of the housing or the cover body through a plurality of wire coiling structures.

[0078] Furthermore, a plurality of wire coiling structures are arranged and installed along the axial direction parallel to the length direction of the device body 200, and the clamping openings 21 of each wire coiling mechanism are arranged in the same direction; for example Figure 3 for the wire coiling structures used by the wire 100 on the upper side in

[0079] and the wire coiling structures used by the wire 100 on the lower side, they are all arranged along the same axial direction, and the clamping openings 21 of each wire coiling structure face the same direction. Figure 3The various coiling structures used by the middle wire 100 among them.

[0080] Distributing the coiling structures on the infrared heating device with the same straight line as the axis can achieve rapid wire drawing and integral wire coiling.

For those of ordinary skill in the art, according to the idea of the embodiments of the present application, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present application.
