Description

TECHNICAL FIELD

[0001] The application relates to the technical field of enameled wire production, in particular to a steel belt roller connecting structure. BACKGROUND

[0002] The existing enameled wire oven generally sets a painting device at the inlet end of the baking channel in the oven. The wire material to be processed into enameled wire first passes through the painting device and is painted on the surface of the wire material by the painting device, then passes through the baking channel and is dried by the drying device, then passes through the return wire channel of the enameled wire oven and returns to the painting device to be painted again, and finally the finished enameled wire is obtained after multiple painting, drying and returning.

[0003] A half-automatic lead guiding device before painting of enameled wire is disclosed in Chinese Patent No. CN212230148U, which comprises four wire rollers and a plurality of wire wheels sleeved on the circumference of each wire roller. The four wire rollers are connected to the rack. The adjacent wire wheels on the same wire roller are provided with a lead guiding wheel, and the lead guiding wheel is sleeved on the circumference of the wire roller. The lead guiding wheels on the four wire rollers are correspondingly arranged along the lead-in direction of the wire material. The corresponding lead guiding wheels on the four wire rollers form a group. The lead guiding wheels in the same group are circumferentially provided with a lead guiding belt. The lead guiding belt is arranged along the rotation direction of the lead guiding wheel. A driving mechanism is connected to the rack. The driving mechanism drives the rotation of the lead guiding wheel. When it is necessary to install the wire material on the wire wheel, the user can first bind the end of the wire material to the lead guiding belt, and then start the driving mechanism to wind the wire material on the four wire rollers.

[0004] However, when the wire material is dragged by the lead guiding wheel through the wire roller, the surface of the wire material will be in relatively large friction with the wire roller, which will cause the worn part of the wire material to be easily broken, resulting in failure of the installation of the wire material.

[0005] Therefore, it is necessary to provide a steel belt roller connecting structure. CONTENT OF THE UTILITY MODEL

[0042] The use process of the first embodiment of the present application in use is as follows:

[0043] Before the semi-automatic lead device is used to automatically lead the wire material, the user can press the plug post 41 in the direction close to the connecting hole until the plug pin is inserted into the plug pin hole, at this time the first elastic piece 43 drives the end of the clamping piece 42 close to the accommodating through hole to rotate in the direction close to the clamping groove and makes the clamping piece 42 inserted into the clamping groove, so that the lead roller 2 and the lead wheel 3 are connected through the plug pin, so that the wire material does not rub against the surface of the lead roller 2 when passing through the lead roller 2, so that the situation that a part of the wire material is worn and then broken when passing through the lead roller 2 is avoided, so that the success rate of automatic installation of the wire material is ensured by the steel belt roller connection structure.
