Description

Technical Field

[0001] The invention relates to the technical field of slitting devices, in particular to a low-smoke halogen-free flame-retardant tape slitting device. Background Art

[0002] Low smoke halogen-free flame retardant tape is a fire-resistant insulating coil, which is made by bonding mica paper and glass cloth with adhesive. Its production process includes gluing, pressing, drying, slitting, and winding. After drying, the low smoke halogen-free flame retardant tape wound on the roller needs to be slit. According to the different specifications of the slit low smoke halogen-free flame retardant tape, the low smoke halogen-free flame retardant tape is slit into different widths, and then the slit low smoke halogen-free flame retardant tape is wound on the material roller, and finally the low smoke halogen-free flame retardant tape wound on the material roller is taken out. Since the low smoke halogen-free flame retardant tape wound on the material roller is more in contact with the outer wall of the material roller, the above-mentioned removal process is more laborious.

[0003] To this end, the Chinese patent with the publication number "CN216785195U" announced "a low-smoke halogen-free flame-retardant tape slitting device", whose main structure includes a first side plate and a second side plate arranged relatively to each other and a winding mechanism, wherein the winding mechanism includes a rotatable rotating head, a plurality of winding parts arranged in a closed manner, and an expansion component. When a plurality of the winding parts are expanded, the outer walls of all the winding parts are closed to form a winding shaft for winding the slit low-smoke halogen-free flame-retardant tape, and also includes a plurality of connecting springs. The low-smoke halogen-free flame-retardant tape slitting device is provided with a plurality of winding parts and an expansion component, and the expansion component can drive the winding part to expand or close. When the winding part is expanded, it is closed into a winding shaft, and the slit low-smoke halogen-free flame-retardant tape can be wound smoothly. When the winding part is closed, it is convenient for the slit low-smoke halogen-free flame-retardant tape to have a certain gap with the winding part after the winding is completed, so that the slit low-smoke halogen-free flame-retardant tape can be easily taken out.

[0004] However, in the actual slitting process, since the equipment relies on the threaded structure to adjust the expansion or closing of the expansion component, and the expansion component needs to generate a rotation function when working, the rotation will cause the internal thread structure and the external thread structure to rotate relative to each other, thereby causing the expansion component to mechanically open and close or mechanically vibrate during expansion, resulting in poor stability during operation.

[0039] When the driven limit plates 510 need to move away from each other, the hydraulic equipment is started to allow the liquid to flow back into the hydraulic equipment.

Similarly, the multiple closing support plates 51 will be closed. At this time, the rolled low-smoke halogen-free flame retardant tape is fixed using a fixing device, and then the detachable vertical support plate 2 is removed, thereby facilitating the removal of the rolled low-smoke halogen-free flame retardant tape.
