[0036] The distance between the clamp two 4 and the clamp three 5 is adjusted by driving the clamp three 5 to move horizontally by the linear motor one 12. When the material is cut into different lengths, the distance between the clamp two 4 and the clamp three 5 is adjusted adaptively, which makes the clamping force of the material more uniform, thereby improving the stability of clamping the material.

[0037] As shown in Figures 1 to 3 As shown in

[0038] As shown in Figures 1 to 3 In this embodiment, a vertical bin 32 is welded between the bottom end of the V-shaped frame one 33 and the top of the cross beam plate 31. A communication hole 38 is formed in the middle end of the V-shaped frame one 33 and communicates with the inside of the vertical bin 32. An electric telescopic rod one 39 is fixed in the vertical bin 32. The movable end of the electric telescopic rod one 39 is fixedly connected with a mounting block 310. A universal ball one 311 is fixed to the end of the mounting block 310 away from the electric telescopic rod one 39. When clamping the material, the electric telescopic rod one 39 is shortened to drive the cross beam plate 31 to move downward, avoiding the universal ball one 311 from contacting the lower surface of the material. When the material needs to be moved up and down, the electric telescopic rod one 39 is extended to make the universal ball one 311 move upward, and the material is slightly lifted up by the universal ball one 311 contacting the lower surface of the material.

[0039] As shown in Figure 4As shown in the drawings, in this embodiment, the cutter assembly 2 comprises an electric telescopic rod two 21 fixed on one side protrusion 11 through a cushion block, the movable end of the electric telescopic rod two 21 is fixedly connected with an E-shaped frame 22, the end of the E-shaped frame 22 away from the electric telescopic rod two 21 is welded with a cutter seat 23, and the end of the cutter seat 23 away from the E-shaped frame 22 is installed with a cutter body 24.

[0040] As shown in the drawings, Figure 4 As shown in the drawings, in this embodiment, the cutter assembly 2 further comprises an electric telescopic rod three 27 fixed on the other side protrusion 11 through a cushion block, and the movable end of the electric telescopic rod three 27 is fixedly connected with an anvil strip 28.

[0041] When cutting the material, the electric telescopic rod three 27 is extended to make the anvil strip 28 abut against one side of the material, and then the electric telescopic rod two 21 is extended to make the cutter body 24 abut against the other side of the material to cut the material, and when cutting the material, the anvil strip 28 provides resistance to the material to avoid displacement of the material during cutting. Meanwhile, the cutter body 24 is cut on the anvil strip 28 during cutting the material, so as to improve the stress point of the cutter body 24 during cutting the material and ensure the cutting effect of the material. The electric telescopic rod two 21 is retracted to drive the cutter body 24 to move transversely, and the electric telescopic rod three 27 is retracted to drive the anvil strip 28 to move transversely, that is, the distance between the cutter body 24 and the anvil strip 28 is adjusted, so as to adjust the distance between the cutter body 24 and the anvil strip 28 according to the size of the material, and ensure that the two can cut the material of different sizes.

[0042] As shown in the drawings, Figure 4 As shown in the drawings, in this embodiment, the bottom end of the cutter seat 23 is welded with a vertical shaft 25, the bottom end of the vertical shaft 25 is installed with a universal ball two 26 rolling on the bottom plate 1, and the universal ball two 26 rolls on the bottom plate 1 to support the cutter seat 23 and ensure the stability thereof.

[0043] In use, the material cavities formed on the clamps one 3, the clamps two 4 and the clamps three 5 for clamping the material are expanded to the maximum, and the process is as follows:

[0044] The linear motor two 37 drives the V-shaped frame two 36 to move upward to expand the distance between the V-shaped frame two 36 and the V-shaped frame one 33, so as to expand the space of the material cavity, so that the material passes through the material cavities on the clamps one 3, the clamps two 4 and the clamps three 5. When it is needed to cut the material, the linear motor two 37 drives the V-shaped frame two 36 to move downward to press the V-shaped frame two 36 on the upper surface of the material, so as to clamp the material between the V-shaped frame one 33 and the V-shaped frame two 36, and then drive the cutter assembly 2 to cut the material;

[0045] When the material is cut, the electric telescopic rod three 27 is extended to make the anvil plate 28 contact with one side of the material, then the electric telescopic rod two 21 is extended to make the cutter body 24 contact with the other side of the material, and the material is cut.
