[0002] The material roll is a continuous strip tightly wound into a cylindrical shape, and the grooves of the material roll need to be cut before processing and use.

[0003] For example, the authorization announcement number CN 218080639U discloses a cutting device for coiled tinplate, which is provided with a pressing piece and a second hydraulic rod. Before cutting the coiled tinplate, the pressing piece is pressed on the coiled tinplate to fix the coiled tinplate. The coiled tinplate is then cut without causing the coiled tinplate to shift in position, thus avoiding the shift in the next cutting position, which is beneficial to the cutting of the coiled tinplate.

[0004] In the above, the raw materials to be cut cannot be cut at fixed distances, and the cutting specifications need to be controlled manually, which is easy to cause errors. During the production process of the material roll, the specifications of the roll material are different depending on the usage scenario. At this time, the cut material roll needs to be accurately cut at fixed distances. Utility Model Content

The frame 1 is provided with a conveyor belt 3, and the cutting knife 2 is placed above the conveyor belt 3. The frame 1 is provided with a control panel 4, and an infrared sensor 10, a gravity sensor, an electric push rod 6, a push cylinder 8 and the cutting knife 2 are all electrically connected to the control panel 4.

[0025] Universal wheels 14 are provided under the frame 1 to facilitate corresponding displacement as the working scene changes.

[0026] A partition 5 is provided above the frame 1, and the partition 5 is placed above the cutting knife 2. A distance component is provided on the partition 5 for cutting the material roll at a fixed distance. A slide groove 12 is opened on the end face of the partition 5, and protrusions 13 for extending into the slide groove 12 are provided on both sides of the mounting seat 7. The protrusion 13 is slidably connected with the slide groove 12 so that the mounting seat 7 can move on the partition 5.

[0027] The distance assembly includes an electric push rod 6, a mounting seat 7, a pushing cylinder 8 and a distance plate 9. The mounting seat 7 is slidably connected to the partition 5, and the output end of the electric push rod 6 is fixedly connected to the side wall of the mounting seat 7. The pushing cylinder 8 is placed on the lower end surface of the mounting seat 7. The pushing cylinder 8 is provided with an outer shell on the outside, and a connecting hole is provided on the outer shell. A docking hole is provided on the mounting seat 7 corresponding to the connecting hole. The connection between the pushing cylinder 8 and the mounting seat 7 is achieved by inserting screws into the docking hole and the connecting hole. The distance plate 9 is connected to the output end of the pushing cylinder 8, and the distance plate 9 can move downward with the output of the pushing cylinder 8.

[0028] The electric push rod 6 and the cutting knife 2 are located on the same straight line. An infrared sensor 10 is provided at one end of the electric push rod 6.

After reaching the set distance, the electric push rod 6 stops working. Since the electric push rod 6 is fixedly connected to the mounting seat 7, the position of the mounting seat 7 will not shift during the working process. Then place the roll on the conveyor belt 3, push the cylinder 8 downward to output until the distance plate 9 contacts the conveyor belt 3. During the transmission process, the roll will gradually move forward until the roll contacts the distance plate 9. The weight sensor 11 is subjected to pressure and feedbacks a signal to the control panel 4, driving the cutting knife 2 to cut. Finally, push the output end of the cylinder 8 to retract, the distance plate 9 to retract, and the cut roll is transmitted out. Repeat the above steps until the roll is cut. When the cutting specifications of the roll need to be adjusted, just adjust the data on the control panel 4.
