A base 6 is arranged on each side of the cylinder assembly 7, and a vertical slide cylinder 61 is fixed on the base 6, a bracket 62 is fixed on the slide of the slide cylinder 61, a linear guide rail 63 is horizontally arranged on the side of the bracket 62, a supporting plate is fixed on the slider of the linear guide rail 63, a linear drive cylinder 64 is fixed on the tail end of the bracket 62, the push rod of the linear drive cylinder 64 is connected to the tail end of the supporting plate, and the linear drive cylinder 64 can drive the supporting plate to slide along the slider of the linear guide rail 63. A clamping jaw 2 is fixed on the supporting plate, and the two clamping jaws 2 move towards or away from each other. A heating block 3 and a blocking part 23 are arranged on the two clamping jaws 2 respectively, and the heating block 3 and the blocking part 23 can cooperate with each other to heat and weld the two ends of the film when the two clamping jaws 2 are close to each other. The specific movement process is as follows: the two clamping jaws 2 are moved upward to remove the butt joint of the incoming material clamp, the two clamping jaws 2 are moved downward to clamp the two ends of the film, the film contacts the upper end of the pipe winding material during the downward movement, and the film covers the upper end and the side of the pipe winding material as the two clamping jaws 2 move downward, and the film further covers the bottom of the pipe winding material when the two clamping jaws 2 move to the position corresponding to the avoiding channel 11. The heating block 3 and the blocking part 23 contact each other to heat and weld the ends of the film when the two clamping jaws 2 abut against each other, and the film forms a closed loop to constrain the pipe winding material. This design integrates winding and heat welding, has high automation degree, and has high bundling efficiency.

[0034] As Figure 3 、 Figure 4 and Figure 5The specific structure of the shown clamping jaw 2 is as follows: the clamping jaw 2 is divided into two parts, i.e., an upper clamping block 21 and a lower clamping block 22, a heating block 3 is connected to the upper side of the upper clamping block 21, and a driving member one 31 is connected to the heating block 3, and the driving member one 31 is preferably a small-stroke air cylinder. The driving member one 31 can drive the heating block 3 to extend or retract to approach or move away from the abutting portion 23.

Further, the top of the guide portion 211 protrudes a supporting and pressing portion 213, which is inclinedly arranged away from the other clamping jaw 2. The guide portion 211 of the present application protrudes the supporting and pressing portion 213, after the clamping jaw 2 moves vertically to cover the restraint film on the local position of the pipe winding material, as the two ends of the restraint film gradually approach each other as the clamping jaws 2 approach each other, the restraint film gradually approaches the pipe winding material by being supported upwardly by the supporting and pressing portion 213, so that the entire restraint film can be tightly wrapped on the outside of the pipe winding after hot-welding, and the overall wrapping effect is better. At the same time, the supporting and pressing portion 213 can shield the lower components to avoid contact and entanglement with the restraint film, and the overall operation stability is better. Further, the clamping surfaces of the upper clamping block 21 and the lower clamping block 22 are respectively provided with protruding ribs and recesses that match each other.The upper clamp block 21 and the lower clamp block 22 of the present application are respectively provided with convex ribs and concave marks, and the concave-convex cooperation can increase the friction when the film is clamped, and improve the clamping stability.

The driving member two 5 which drives the lower clamp block 22 to move is a two-fingered cylinder. The lower clamp block 22 is connected with one driving finger 51 of the two-fingered cylinder, and the other driving finger 51 is in a free state. In this way, one driving finger 51 drives the lower clamp block 22 to move. This design halves the moving stroke of the lower clamp block 22 relative to the upper clamp block 21, and is more suitable for clamping the film. The moving efficiency is improved while the clamping stability is taken into account. At the same time, the end of the driving finger 51 in the free state can keep the guided movement of the lower clamp block 22, so that the movement of the lower clamp block 22 is more stable, and the clamping stability is further improved.
