[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0023] Please refer to Figures 1-5, the utility model provides a rapid edge cutting mechanism for pre-coated film production, including a cutting platform 1, a feeding roller 2, a winding roller 3, a waste edge collecting roller 4, a slide rail 5, a power box 501, a bracket 502, a motor 503, a lead screw 504, a chute 505, a cutting tool connecting seat 6, a cutting blade 601, a slider 602, an adjusting block 603, a threaded hole 604, a buffer block 605, a buffer rod 606, a pressing piece 7, a buffer groove 701, a spring 702, a limiting slider 703, a pressing roller 8, and a pressing roller bracket 801. A feeding roller 2 is arranged on the top of the cutting platform 1. A winding roller 3 is arranged on one side of the feeding roller 2. A waste edge collecting roller 4 is arranged on the side of the winding roller 3 close to the feeding roller 2, and the height position of the waste edge collecting roller 4 is higher than that of the winding roller 3. Two groups of parallel slide rails 5 are arranged between the waste edge collecting roller 4 and the feeding roller 2. Two power boxes 501 are fixedly connected to both ends of the two groups of slide rails 5. A motor 503 is installed inside one of the two power boxes 501. A lead screw 504 is arranged on the side of the motor 503 close to the slide rail 5. Both ends of the lead screw 504 are rotatably connected to the two power boxes 501. The thread structure on the surface of the lead screw 504 is divided into two parts, and the thread structures of the two parts are mirror images of each other. In this way, when the lead screw 504 rotates, the moving directions of the two adjusting blocks 603 can be opposite, which is convenient for adjusting the distance between the two adjusting blocks 603, so as to adjust the cutting width.

[0024] The bottom of the power box 501 is fixed with a bracket 502, which is fixedly connected to the top of the cutting platform 1. Two cutting tool connecting seats 6 are arranged between the two groups of slide rails 5. A rectangular slider 602 is fixed on the side of the cutting tool connecting seat 6 close to the two groups of slide rails 5. The slider 602 is slidably connected to the slide rail 5, and a chute 505 is opened at the connection between the slide rail 5 and the slider 602, which can make the movement of the cutting tool connecting seat 6 more stable. An adjusting block 603 is fixed on the top of the cutting tool connecting seat 6. The adjusting block 603 is threadedly connected to the lead screw 504, and a threaded hole 604 is opened at the connection between the adjusting block 603 and the lead screw 504. A cutting blade 601 is fixedly arranged at the bottom of the cutting tool connecting seat 6. The arranged adjusting block 603 can drive the cutting tool connecting seat 6 to move when the lead screw 504 rotates, which is convenient for adjusting the distance between the two cutting tool connecting seats 6 and convenient for cutting pre-coated films of different widths. Two buffer blocks 605 are fixed at the bottom of the cutting tool connecting seat 6, and the two buffer blocks 605 are arranged at both ends of the two pressing pieces 7. The cross section of the buffer block 605 is an "L" - shaped structure. The arranged buffer blocks 605 can prevent the two pressing pieces 7 from moving downward and separating from the cutting tool connecting seat 6.

[0025] At the bottom of each cutter connecting seat 6, two pressing plates 7 are provided. The two pressing plates 7 are distributed on both sides of the cutting blade 601, and the cutting blade 601 does not contact the side surface of the pressing plate 7. At both ends of the pressing plate 7 near the top of the slide rail 5, limit sliders 703 are fixed. The limit sliders 703 are slidably connected to the buffer blocks 605. The provided pressing plate 7 can press both sides of the pre-coated film cut by the cutting blade 601 to prevent the edges from warping during cutting by the cutting blade 601, resulting in damage to the cutting edge. Two buffer grooves 701 are formed at the top of the pressing plate 7. A buffer rod 606 is slidably connected inside the buffer groove 701. The top of the buffer rod 606 is fixedly connected to the bottom of the slide rail 5. A spring 702 is provided inside the buffer groove 701. The provided buffer groove and the spring 702 inside can allow the pressing plate 7 to move up and down to adapt to pre-coated films of different thicknesses, fix them, and smooth the cutting part. The bottom surface of the pressing plate 7 is slidably connected to the cutting platform 1. The two ends of the bottom surface of the pressing plate 7 near the slide rail 5 are arc-shaped structures, and the bottom surface structure of the pressing plate 7 is smooth. The arc surface can facilitate the passage of the pre-coated film from below and prevent damage to the pre-coated film. A pressure roller bracket 801 is fixed on the outer side surface of the slide rail 5, and a pressure roller 8 is installed at the lower end of the pressure roller bracket 801 close to the cutting platform 1.

[0026] When the embodiment of the present application is in use: By arranging pressing sheets 7 on both side surfaces of the cutting blade 601, the pressing sheets 7 can move downward through their own weights and the springs 702 inside the buffer grooves 701 to flatten the edges of the pre-coated film passing through the cutting blade 601, avoiding the situation that the edges warp during cutting, resulting in uneven cutting. The springs 702 inside the buffer grooves 701 can allow the pressing sheets 7 to float up and down to adapt to pre-coated films of different thicknesses, tightly attaching pre-coated films of different thicknesses to the surface of the cutting platform 1. When the motor 503 is started, the motor 503 can drive the lead screw 504 to rotate. When the lead screw 504 rotates, it can drive the cutting tool connecting seat 6 to move inside the two sets of slide rails 5 through the adjusting block 603. By means of the sliders 602 on both sides of the cutting tool connecting seat 6, the sliding of the cutting tool connecting seat 6 can be avoided, so that the distance between the two sets of cutting tool connecting seats 6 can be adjusted, and then pre-coated films of different width dimensions can be cut. When the cutting tool connecting seat 6 moves, the length of the pressing roller 8 outside the slide rail 5 remains unchanged, and it can still continue to flatten the passing pre-coated film, making it move horizontally on the surface of the cutting platform 1 and pass under the cutting blade 601 to complete the cutting. In this way, the device can conveniently cut pre-coated films of different widths and also press and hold the cutting edges to avoid the situation that the cutting edges are damaged due to uneven force. In this way, a fast edge-cutting mechanism for pre-coated film production is used up. It should be noted that the present utility model is a fast edge-cutting mechanism for pre-coated film production, and the components are all common standard parts or parts known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or obtained through conventional experimental methods. At the idle places of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted monitoring computer and power supply, are connected through wires. For the specific connection means, reference should be made to the above working principle to complete the electrical connection according to the sequence of operation of each electrical component.
