[0040] Reference Figure 1 The cutting system is used for cutting the sheet material, and includes a cutting device 300. The cutting device 300 includes a first bracket 350, a cutter 320, a film roller 340 and a pressure roller 330. The first bracket 350 is provided with a cutting platform 310. The cutter 320 is arranged above the front end of the cutting platform 310. The film roller 340 is used to provide a film member adhered to the sheet material. The pressure roller 330 is arranged above the cutting platform 310. The pressure roller 330 and the cutter 320 are arranged in sequence from back to front. The pressure roller 330 can roll the sheet material with the film member adhered, and the pressure roller 330 is connected to an encoder.

[0041] Figure 1 In the simple schematic diagram, the structure of the first bracket 350 for connecting the cutter 320 is omitted. The cutter 320 is movably connected to the first bracket 350 and can move up and down. The cutter 320 is connected to a material cutting power member 360. For example, the material cutting power member 360 includes a crank articulated with a frame, a connecting rod connected to the crank at one end and connected to the cutter at the other end, and the crank, the connecting rod and the cutter 320 that moves up and down form a crank slider mechanism. Generally, the crank is driven to rotate by a corresponding motor, see Figure 7 The cutting power member 360 can also be simply a cylinder body, which directly drives the cutter 320 to move up and down. The cylinder body is a common air cylinder, hydraulic cylinder and electric cylinder.

[0042] Encoders are common knowledge for those skilled in the art. They are usually connected to the shaft end, detect the angular displacement of the shaft, and then convert the linear displacement of the shaft wall according to a physical formula: linear displacement = angular displacement × radius.

[0043] Reference Figure 1 , the sheet material transmission direction is V1, and the film piece winding direction is V2. A material cutting method comprises the following steps:

[0044] Plate feeding, the plate is fed to the rear end of the cutting platform 310;

[0045] Film lamination and feeding amount detection, the sheet is placed under the pressing roller 330, a film roll is mounted on the film roller 340, the film pulled out from the film roller 340 is also placed under the pressing roller 330, and the film is attached to the upper end of the sheet, the pressing roller 330 rolls the film and the sheet to make the film lamination on the sheet, the encoder connected to the pressing roller 330 is used to detect the amount of the sheet feeding under the cutter 320;

[0046] To cut the plate, the plate is fed a predetermined amount L below the cutter 320 each time, and then the feeding is stopped and the cutter 320 moves down to cut the plate.

[0047] It is understandable that after the equipment is designed, the distance between the pressure roller and the cutter in the front-to-back direction is fixed. If a plate of length L passes through the pressure roller, a plate of length L must pass under the cutter. Each time the plate is fed under the cutter 320 by a predetermined amount L, the feeding is stopped, and the cutter 320 moves down to cut the plate.

[0048] Therefore, the pressure roller 330 rolls the plate and rotates with the plate or is used to drive the plate to be transmitted. It can be used to drive the film to be tightly attached to the plate, and can also be combined with an encoder to detect the transmission amount of the plate and the amount of film used. The simplified equipment structure can simultaneously perform film pasting and fixed-length cutting of the plate.

[0049] In the material cutting method, the first one cut from the coil is generally discarded. For example, for a new sheet coil that has just started to be cut, the first end is generally manually pasted with film; that is, in the material cutting method, the film is manually pressed and scraped toward the first end of the sheet, and the film is pasted to the first end of the sheet based on its own softness and adsorption. The first end begins to be placed in the pressing roller 330, and thereafter the sheet and the film are automatically placed in the pressing roller 330 and lowered due to the pulling of the front section of themselves. The first sheet cut is mainly manually pasted with film, and the size may be shorter, so it is generally discarded. If the material cutting is suspended due to lunch break / shift work, etc., when the material cutting is restarted, the first sheet is still mechanically automatically pasted with film, and the sheet continues to be fed from the paused position. The size deviation is not large, and it is determined whether it is a qualified product after product inspection.

[0050] Reference Figure 1 In some embodiments of the present invention, the cutting device 300 further includes a pressing plate assembly 370. The pressing roller 330, the pressing plate assembly 370 and the cutter 320 are arranged in sequence from the back to the front. The pressing plate assembly 370 includes a pressing block 371 and a first lifting power member 372. At least one pressing block 371 is arranged in the left-right direction and connected to the corresponding first lifting power member 372. It can be understood that in the plate cutting method, when the plate stops feeding below the cutter 320, the pressing block 371 presses the plate. During the process of the cutter 320 cutting the plate, the plate is not easy to move, and the plate behind the cutter 320 is not easy to tilt. Figure 1In the simplified diagram, part of the structure on the first bracket 350 for mounting the pressure plate assembly 370 is omitted; a horizontal bar is provided on the first bracket 350, and a plurality of first lifting power members 372 are arranged side by side on the horizontal bar along the left-right direction.

[0051] Reference Figure 1 In some embodiments of the present invention, the cutting device 300 further includes a limit plate 380 disposed above the cutting platform 310. The limit plate 380 and the cutter 320 are disposed sequentially from the back to the front, and a limit channel is formed between the limit plate 380 and the cutting platform 310 to allow the plate to pass through. It can be understood that in the plate cutting method, the plate is transferred to the bottom of the cutter 320, and the limit channel is used to straighten the plate. When the cutter 320 cuts the plate, the plate behind the cutter 320 is not easy to bend. Figure 1 In the simplified diagram, part of the structure of the limiting plate 380 on the first bracket 350 is omitted; the left and right ends of the limiting plate 380 are connected to the first bracket 350 .

[0052] Reference Figure 1 , Figure 7 and Figure 8 In some embodiments of the present invention, it also includes a material receiving device 400 arranged in front of the cutting device 300, the material receiving device 400 includes a stacking mechanism 410 and a positioning frame 420, the stacking mechanism 410 includes a stacking table 411 and a second lifting power member 412 for driving the stacking table 411 to rise and fall; the positioning frame 420 surrounds the stacking mechanism 410, and the upper end of the positioning frame 420 is provided with a guide slope 421a at the rear end, left end and right end, so that the upper end of the positioning frame 420 is narrowed from top to bottom. The sheet material is mechanically connected. In the material cutting method, the sheet material can extend from the output end of the cutting device 300, the stacking table 411 rises to support the protruding part of the sheet material, and then the sheet material of the protruding part is cut off, the stacking table 411 descends and the sheet material is stopped by the guide slopes 421a at the rear end, left end and right end of the positioning frame 420. The sheet material moves horizontally during the falling process and then aligns with other stacked sheets to become the top sheet material; in the material cutting method, the stacking table 411 can also be aligned with the lower end of the guide slope 421a, the cut sheet material falls and is stopped by the guide slope 421a, so the sheet material moves horizontally during the falling process and is finally neatly stacked on the stacking table 411; the sheet material is already in a state of suspended forward movement during cutting, the corresponding guide slope 421a is not set at the front end of the positioning frame 420, and the corresponding guide slope 421a is set at the rear end of the positioning frame 420, the sheet material is aligned forward, and forklifts and other equipment can also transfer several stacked sheets at the front end of the positioning frame 420.

[0053] Reference Figure 7 and Figure 8In some embodiments of the present invention, the receiving device 400 further includes a receiving mechanism 430 higher than the positioning frame 420, the receiving mechanism 430 includes a second bracket 431, a receiving power member 432, and support brackets 433 connected to the left and right ends of the second bracket 431, and the receiving power member 432 is used to drive the support brackets 433 to move in the left and right directions, so that the two support brackets 433 are close to or far away from each other. In the cutting method, the plate is supported by the support brackets 433 during cutting, and the plate is not easy to crack automatically during the cutting process, ensuring the neatness and correctness of the cutting edge line; the support brackets 433 are far away from each other, and the cut plate is more likely to lose support at both ends, and the plate is closer to falling as a whole plate during the falling process.

[0054] Reference Figure 7 In some embodiments of the present invention, the material receiving power member 432 is two material receiving cylinders arranged on a bracket, and the material receiving cylinders are connected to the corresponding support brackets 433. The cylinder power mode is adopted, and the structure is simpler. In some embodiments, the material receiving power member adopts a combination structure of a motor and a screw nut pair, a combination structure of a motor and a belt, or a combination structure of a motor and a gear rack, etc.

[0055] Reference Figure 7 In some embodiments of the present invention, at least two supporting arms 433a are arranged in a front-to-back direction at the opposite ends of the two supporting brackets 433, at least two inclined rods 421 are arranged in a front-to-back direction at the left and right ends of the upper end of the positioning frame 420, the guide slope 421a is formed by the corresponding at least two inclined rods 421, and the supporting arms 433a and the corresponding inclined rods 421 are misaligned in the front-to-back direction. Even if the plate is temporarily difficult to separate from the supporting arms 433a, when the supporting arms 433a are evacuated outwards in the left-right direction between the two corresponding inclined rods 421, the plate will be stopped by the inclined rods 421, and the plate will be scraped off the supporting arms 433a.

[0056] In some embodiments of the present invention, the material receiving power member 432 is connected to the second bracket 431 through the third lifting power member, and the support bracket 433 can move up and down. Therefore, the two support brackets 433 can be lifted and lowered and can move away from or close to each other in the left and right directions. After the cut plates are connected, the support brackets 433 can first be lowered and then moved away from each other. After the cut plates are lowered to a lower level, they can be lowered along the guide slope 421a. The support brackets 433 drive the plates to a certain height and then move away from each other. The plates can be dragged down by their own gravity or scraped away by the inclined rods 421.

[0057] Reference Figure 7 In some embodiments of the present invention, a ball 434 is disposed at the upper end of the support frame 433, and the ball 434 partially protrudes upward from the support frame 433 to support the plate. The plate can be smoothly separated from the support frame 433.

[0058] In some embodiments of the present invention, an industrial pallet is placed on the upper end of the stacking platform 411. The stacking platform 411 can directly place the industrial pallet, and the front end of the positioning frame 420 is not provided with a diagonal rod 421 and other structures. After a sufficient amount of plates are stacked on the industrial pallet, a forklift directly forks the industrial pallet in front of the positioning frame 420.

[0059] Reference Figure 7 and Figure 8 In some embodiments of the present invention, the first lifting power member 372 is a lifting cylinder connected to the lower end of the stacking platform 411. With the cylinder structure, the first lifting power member 372 will not partially protrude toward the upper end of the stacking platform 411. This structure is simpler and there are no many obstacles when the plates are stacked on the stacking platform 411. In some embodiments, the material receiving power member adopts a combination structure of a motor and a lead screw nut pair, a combination structure of a motor and a belt, or a combination structure of a motor and a gear rack, etc. In these structures, the lead screw, belt, and rack extend above and below the stacking platform.

[0060] In some embodiments of the present invention, a high-position detection switch and a low-position detection switch are provided on the positioning frame 420. The high-position detection switch is used to detect the topmost plate on the stacking platform 411, and the low-position detection switch is used to detect the lower end of the stacking platform 411. The high-position detection switch can detect the topmost plate on the stacking platform 411 or the upper end of the stacking platform 411, so that the topmost plate or the upper end of the stacking platform 411 is aligned with the lower end of the guide slope 421a, and the plate falls along the guide slope 421a, and the falling height is small, the inertia generated is small, and it is not easy to fall in a mess; when the stacking platform 411 drops to an appropriate height, the low-position detection switch is detected, which also means that a sufficient amount of plates are stacked on the stacking platform 411.
