[0019] Combined with appendix Figures 1 to 3 As shown, this embodiment discloses a portable pipe wrapping film cutting device with replaceable heating wire, including a lifting mechanism, a main mounting frame 4, a cutting heating wire 7, a heating conductive movable block 11, a heating wire guide block 1, and a buffer guide mechanism.

[0020] The buffer guide mechanism includes a buffer spring 9, a conductive block movable slot 2, and a conductive block limiting block 3. The conductive block movable slot 2 is fixed on the overall mounting frame 4. The conductive block movable slot 2 is provided with a square slot. The heating conductive movable block 11 is disposed in the square slot and can slide up and down in the square slot. The conductive block limiting block 3 is disposed below the conductive block movable slot 2. Two hexagonal socket screws are sequentially inserted into the conductive block limiting block 3 and the guide block movable slot 2 and connected to the overall mounting frame by threads, thereby fixing the conductive block limiting block 3 and the guide block movable slot 2 to the overall mounting frame 4.

[0021] A buffer spring 9 is provided between the heating conductive movable block 11 and the heating wire guide block 1. The top of the heating conductive movable block 11 has a cylindrical hole for placing the spring, and the bottom of the heating wire guide block 1 has a cylindrical hole for placing the spring. The two ends of the buffer spring 9 are respectively located in the cylindrical holes on the heating conductive movable block 11 and the heating wire guide block 1. The cutting heating wire 7 is tightened by the elastic force of the buffer springs 9 on both sides, while the buffer springs 9 on both sides also give the cutting heating wire 7 a certain degree of flexibility to prevent it from breaking during film cutting due to excessive tension.

[0022] The cutting heating wire 7 includes a nickel-chromium alloy heating wire and two wire lugs, which are respectively connected to the two ends of the nickel-chromium alloy heating wire. The heating conductive movable block 11 has two terminals on its side, which are respectively used to connect the power cord and the wire lugs of the cutting heating wire 7.

[0023] The lifting mechanism is a lifting and cutting cylinder 6. The lower part of the overall mounting frame 4 is connected to the lifting and cutting cylinder 6. A lifting connecting plate 10 is provided on the movable block of the lifting and cutting cylinder 6. Two quick-release positioning pins 8 are symmetrically arranged on the lifting connecting plate 10, and the quick-release positioning pins 8 are fixed to the lifting connecting plate 10 by threaded connection. The overall mounting frame 4 is provided with corresponding positioning holes. The quick-release positioning pins 8 are inserted into the positioning holes to position the overall mounting frame 4. The overall mounting frame 4 and the lifting connecting plate 10 are fixedly connected by quick-release indexing pins 5, and the quick-release indexing pins 8 are fixed to the overall mounting frame 4 by threaded connection. The overall mounting frame 4 is fitted onto the lifting connecting plate 10 and fixed to the lifting connecting plate 10 by quick-release indexing pins.

[0024] The specific implementation process of this utility model device in the production process is as follows: First, the lifting and cutting cylinder 6 of the device is fixed on the winding equipment, and at the same time, the heating power supply is connected to the lower terminal of the heating conductive movable block 11. Then, the device is started. When the winding equipment wraps the film at the PE pipe port, and the film is clamped by the winding equipment clamping device, the heating conductive movable blocks 11 on both sides are instantly connected to the power supply, and the cutting heating wire 7 is instantly heated. Then, the lifting and cutting cylinder 6 drives the lifting connecting plate 10 and its upper components to move upward, and the cutting heating wire 7 is driven upward to thermally cut the film. Then, the power supply to the heating conductive movable blocks 11 on both sides is disconnected, the cutting heating wire 7 stops heating and begins to cool down. At the same time, the lifting and cutting cylinder 6 drives the lifting connecting plate 10 and its upper components to move downward, and then the winding equipment begins to wait for the arrival of the next pipe to wrap the port film, and so on. During the process of cutting the winding film by cutting the heating wire 7, the heating conductive movable block 11 can move upward under the action of the buffer spring 9, so that the cutting heating wire 7 can undergo slight deformation, thereby avoiding breakage due to excessive tension. This function can also prevent the cutting heating wire 7 from breaking due to deformation caused by its own thermal expansion and contraction.

[0025] When the heating wire 7 breaks and needs to be replaced, the internal space of the winding equipment is relatively small, making direct repairs inside the equipment inconvenient. Instead, the quick-release pin 5 can be pulled out first, and the overall mounting bracket 4, along with its components, can be pulled upwards and removed from the winding equipment for replacement of the heating wire 7. After replacement, the overall movable mounting bracket 4 is fitted onto the lifting connecting plate 10 using the two quick-release positioning pins 8 on the lifting connecting plate 10. Finally, the quick-release pin 5 is inserted to fix the overall mounting bracket 4 onto the lifting connecting plate 10, making the replacement of the broken heating wire simple and quick.

[0026] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
