Support columns are arranged at the bottom of the support platform 1 to lift the support platform 1 to a certain height. A receiving roller 14 is erected at the discharging end of the support platform 1 through a cantilever, and the receiving roller 14 is rotatably connected to the cantilever; the cutting unit 2 is erected on the support platform 1 and performs cutting operations along the width direction of the support platform 1; the positioning units 3 are arranged on both sides of the cutting unit 2 and press the belt on both sides of the cutting operation position to prevent the belt from shifting during cutting; the feeding limiting unit 4 is installed at the feeding end of the support platform 1 to feed the belt along a predetermined path and into the support platform 1.
[0023] In some preferred embodiments, the feeding limiting unit 4 includes a carrying roller 5, a supporting roller 6, limiting side plates 7 and telescopic push rods 8; the carrying roller 5 winds the belt, is located outside the feeding end of the supporting platform 1, is connected to the rotary drive 11, and can release the wound belt when rotating. The supporting roller 6 is located at the feeding end of the supporting platform 1 to support the belt. One end of the released belt passes through the supporting roller 6 and enters the supporting platform 1. The supporting roller 6 can be set in multiple groups to limit and support the belt on the belt feeding path; the limiting side plates 7 are located on both sides of the belt feeding path and can be located between the carrying roller 5 and the supporting roller 6. In this embodiment, the carrying roller 5 is located at a lower position and the supporting roller 6 is located at a higher position. At this time, the limiting side plates 7 can be inclined along the belt feeding path. The distance between the two limiting side plates 7 is adjusted by the telescopic push rod 8, so as to limit belts of different widths on the feeding path.
[0024] Specifically, the carrying roller 5 is rotatably mounted outside the feeding end through a cantilever, and the carrying roller 5 is rotatably connected to the cantilever; one end of the carrying roller 5 is connected to the rotary drive 11, and the rotary drive 11 is installed on the side wall of the corresponding cantilever. The output end of the rotary drive 11 is fixedly connected to one end of the carrying roller 5. When the rotary drive 11 is started, the carrying roller 5 rotates and can release the wound belt.
[0025] The supporting roller 6 is rotatably mounted at the feeding end of the supporting platform 1 and is opposite to the carrying roller 5; the supporting roller 6 can be set in one group, two groups or multiple groups according to factors such as the actual length of the supporting platform 1 to limit and support the belt on the belt feeding path;
[0026] The limiting side plates 7 have corresponding limiting working lengths and are respectively located on the sides of the carrying roller 5 and the supporting roller 6; and one end of the limiting side plate 7 can also extend along the belt feeding direction to the positioning unit 3 to extend the limiting working length. The telescopic push rods 8 are respectively installed on both sides of the feeding end of the supporting platform 1 and are connected to the limiting side plates 7, and can adjust the distance between the limiting side plates 7 to limit belts of different widths and avoid feeding deviation.

When the hydraulic push rod 9 operates to press down the positioning member 10, the pressing working surface of the positioning member 10 presses on the belt, and the guiding member extends into the through hole 16 to limit the positioning member 10, reducing the influence on the pressing effect due to the shaking generated by cutting.
[0029] In some preferred embodiments, further, the cutting unit 2 includes a cutting tool 12 and a hydraulic push rod 13 for driving the cutting tool 12. The hydraulic push rod 13 is mounted on the support platform 1, and the tool has a corresponding cutting operation length.

The sliding rod 18 is located on both sides of the hydraulic push rod 13 respectively. The sliding rod 18 is fixedly connected to the tool, and a connecting rod is fixedly connected between the two sliding rods 18. When the hydraulic push rod 13 controls the cutting tool to press down, the two sliding rods 18 are on both sides, improving the stability of the tool pressing down.

A mark can be made at the position of the belt to be cut, and the winding roller winds up an appropriate length of the belt so that the marked cutting position is located below the cutting tool; at this time, control the hydraulic push rod 9, and the positioning members 10 on both sides of the cutting position press down on the corresponding positions of the belt to position the belt. After positioning, start the hydraulic push rod 13 to press down the cutting tool to perform the cutting operation of the belt.
