The upper telescopic cylinder 301 is a hydraulic cylinder or an electric rod structure. The top of the upper telescopic cylinder 301 is fixedly connected to the upper bracket 302, and a lower cutting support plate 303 is fixed to the lower part of the upper bracket 302. The lower cutting support plate 303 is located below the cutting tool 3. The lower cutting support plate 303 is located at the tail end of the lower conveying frame 1, and the cutting tool 3 is located at the tail end of the upper conveying frame 2. The cutting tool 3 moves downward to approach the copper wire in the middle of the lower cutting support plate 303 to perform segmented cutting operations.

[0032] In the disclosed embodiment, the upper conveyor belt 202 is above the lower conveyor belt 102, and the lower screw 204 is screwed to the outer side of the lower conveyor frame 1. The lower screw 204 moves axially upward along the thread, and the lower screw 204 supports the side support spring 205 to move upward. The side support spring 205 and the side bracket 203 and the upper conveyor frame 2 move upward synchronously, and the distance between the upper conveyor frame 2 and the lower conveyor frame 1 increases, further reducing the downward pressure of the upper conveyor frame 2 on the copper wire on the top of the lower conveyor frame 1.

The upper conveying frame 2 is pressed down by gravity to fit on the copper wire on the top of the lower conveying frame 1. The upper conveying frame 2 is pressed down to flatten the bent copper wire, eliminating the need for personnel to manually flatten the copper wire. There is no need to flatten the copper wire, which reduces the workload of personnel and shortens the copper wire cutting time.

[0035] The working principle of this embodiment is as follows: the copper wire that needs to be cut is placed on the top of the lower conveyor belt 102, the driving motor 103 is started to drive the lower conveyor roller 101 to rotate, the lower conveyor roller 101 drives the lower conveyor belt 102 to move in a circular motion, the lower conveyor belt 102 and the top to be cut The copper wire moves synchronously, the lower conveyor roller 101 engages to drive the lower transmission shaft 104 to rotate, the lower transmission shaft 104 and the upper transmission shaft 206 rotate synchronously, the upper transmission shaft 206 engages and drives the upper conveyor roller 201 to rotate synchronously, the upper conveyor roller 201 and the upper conveyor frame 2 move synchronously and circularly, the upper conveyor frame 2 and the lower conveyor frame 1 move at the same speed, and while the lower conveyor frame 1 is conveying the copper wire, the upper conveyor frame 2 presses down the copper wire on the top of the lower conveyor frame 1 to adjust the curved shape of the wound and collected copper wire after unfolding The copper wire of the upper conveying frame 2 is flattened, and the copper wire is pressed into a flat state to ensure that it remains flat during cutting. After the copper wire passes through a distance required to be cut by the cutting tool 3, the upper telescopic cylinder 301 is extended to support the cutting tool 3 to descend, and the cutting tool 3 moves down close to the lower cutting support plate 303 to perform segmented cutting of the copper wire. The segmented copper wire enters the collection box at the rear of the cutting tool 3. The flat copper wire is more convenient for the cutting operation of the cutting tool 3. At the same time, the flatness makes the cutting position of the cutting tool 3 more accurate, avoiding the increase of cutting error caused by the bending of the copper wire and cutting the lamp beads welded on the copper wire, thereby improving the cutting accuracy and eliminating the need for personnel to manually flatten the copper wire. There is no need to flatten the copper wire, which reduces the workload of personnel and shortens the preparation time before copper wire cutting.

[0036] The upper conveying frame 2 is pressed down by gravity to fit on the copper wire at the top of the lower conveying frame 1, and the side support spring 205 supports the upper conveying frame 2 to reduce the downward pressure of the upper conveying frame 2. The upper conveying frame 2 is stretched by the side support spring 205 to perform a certain range of up and down movement buffering, which has a mobile buffering and reduces the pressure for the welding lamp beads on the copper wire to avoid excessive downward pressure from crushing the welding lamp beads on the copper wire. The lower screw 204 is axially moved upward along the thread, and the lower screw 204 supports the side support spring 205 to move upward. The side support spring 205 and the side bracket 203 and the upper conveying frame 2 move upward synchronously, and the distance between the upper conveying frame 2 and the lower conveying frame 1 is increased. , further reducing the downward pressure of the upper conveying frame 2 on the copper wire on the top of the lower conveying frame 1, and through the lower screw 204 moving axially downward along the thread, the lower screw 204 drives the side support spring 205 to move downward, and the side support spring 205 and the side bracket 203 and the upper conveying frame 2 move downward synchronously, and the distance between the upper conveying frame 2 and the lower conveying frame 1 is reduced. The telescopic sliding between the lower transmission shaft 104 and the upper transmission shaft 206 adapts to the change in the distance between the upper conveying frame 2 and the lower conveying frame 1, further increasing the downward pressure of the upper conveying frame 2 on the copper wire on the top of the lower conveying frame 1, and the axial movement adjustment position of the lower screw 204 is realized to realize the adjustment of the upper conveying frame 2.
