[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] See also Figure 1-Figure 2 , which is a multi-layer material cutting line disclosed in the utility model, mainly includes a plurality of unwinding devices 1 for placing and unwinding material rolls, a transport device 2 for transporting materials and a cutting device 3 for cutting materials.

[0022] In this embodiment, a plurality of unwinding devices 1 are arranged in sequence in a horizontal direction, and the number of unwinding devices 1 can be adjusted at any time according to production requirements. Each unwinding device 1 specifically includes a material roll 11 for placing a material roll. Before cutting, a layer of each material roll is pulled out from the corresponding material roll 11 and multiple layers of material are overlapped.

[0023] The transport device 2 specifically includes a conveyor belt 21 and a material pulling clamp 22 that can be opened and closed. The material pulling clamp 22 can move along the length direction of the conveyor belt 21 while moving along the transmission of the conveyor belt 21. The material pulling clamp 22 specifically includes a movable plate that can move along the length direction of the conveyor belt 21. The movable plate is connected with a clamping plate driven by a cylinder to rise and fall. The conveyor belt 21 is arranged between the movable plate and the clamping plate. The material is unrolled from the material reel 11 and placed on the conveyor belt 21 after being stacked. The clamping plate in the material pulling clamp 22 descends to clamp the multi-layer material and the conveyor belt 21 together. Then the conveyor belt 21 is driven. The material pulling clamp 22 clamps the multi-layer material and along with the transmission of the conveyor belt 21, the material pulling clamp 22 and the conveyor belt 21 cooperate to drive the multi-layer material into the cutting device 3 for cutting. At this time, the material pulling clamp 22 positions the stacked multi-layer material to avoid the multi-layer material from being misaligned with each other during the transmission of the conveyor belt 21, so as to ensure that the subsequent cutting device 3 can cut at the accurate cutting position. After one cutting, the clamping plate in the material pulling clamp 22 rises to release the multi-layer material and the conveyor belt 21, and the conveyor belt 21 continues to drive the cut multi-layer material to leave the cutting device 3. At this time, the material pulling clamp 22 returns to the original position close to the unwinding device 1 to carry out the next material clamping and transportation. During the cutting process, only one material stacking is required, and cutting can be continued, which replaces the method of repeatedly stacking materials after cutting in the prior art, greatly improving production efficiency.

[0024] On the other hand, during the movement of the multi-layer material, each material roll 11 continuously rotates to discharge the material. Since the material roll 11 will continue to rotate due to inertia, it will cause excessive discharge. To avoid this situation, a buffer component is installed on each material roll 11. The buffer component can be preferably one of a magnetic powder brake and a gravity controller to provide a certain resistance to the rotation of the material roll 11. A discharge buffer 12 is provided on the side of the material roll 11 close to the conveyor belt 21. Each layer of material passes through the corresponding discharge buffer 12 before being overlapped, which can effectively buffer or adjust the discharge speed of the material roll 11.

[0025] In order to make the structure of the entire cutting line more compact and reduce the demand for production space of the entire cutting line, the conveyor belt 21 passes through the cutting device 3, and the cutting device 3 divides the conveyor belt 21 into a loading area 211 and a unloading area 212. A plurality of unwinding devices 1 are arranged near the loading area 211, and the pulling clamp 22 is arranged in the loading area 211. Figure 2As shown, the operator can connect other unloading devices near the unloading area 212 to cooperate with the unloading of the cut multi-layer material, so as to improve the automation of the entire cutting line. Furthermore, the loading area 211 and the unloading area 212 are both provided with openable and closable positioning clips 23 near the cutting device 3. Before cutting, when the multi-layer material enters the cutting device 3 with the transmission of the conveyor belt 21, the two positioning clips 23 clamp the two ends of the multi-layer material respectively to position the multi-layer material, avoid the displacement of the multi-layer material during the cutting process of the cutting device 3, and ensure the cutting accuracy.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
