The knife seat 43 is annular and slidably connected to the outside of the hollow column 41 and fixedly connected to the feed block 52. An annular cutter 44 for cutting the film is fixed to the outside of the knife seat 43. A guide rod 6 is rotatably connected between the two side walls of the mounting frame 4. A linkage component for driving the guide rod 6 to rotate is provided between the guide rod 6 and the hollow column 41. Each feed block 52 is fixedly connected to a knife seat 43. The top of the feeding block 52 is fixedly connected with a moving frame 63, and the moving frame 63 is an inverted U-shaped plate. The two side walls of the moving frame 63 are elastically provided with grinding blocks 65, and the two grinding blocks 65 are matched with the two sides of the cutter 44. The two grinding blocks 65 are located on both sides of the cutter 44 and do not contact the cutter 44. A driving component is matched between the side walls of the moving frame 63 and the corresponding grinding blocks 65. In actual use, the coating device 3 is first used to coat the glass, and the coated glass panel is transported and moved by the conveying component 2. During the transportation process, the external motor is used to 42 drives the hollow column 41 to rotate, and the rotation of the hollow column 41 drives the cutter 44 to rotate to cut the excess film on both sides of the glass panel. The driving component is used to drive the two grinding blocks 65 to approach and fit the corresponding two sides of the cutter 44. During the rotation of the hollow column 41, it can drive the guide rod 6 to rotate, and the rotation of the guide rod 6 drives the grinding block 65 to rotate to grind the cutter 44, which can ensure the sharpness of the cutting of the cutter 44. A cleaning component for cleaning the cutter 44 is also provided on the movable frame 63. The driving component is started to drive the grinding blocks 65 on both sides to clamp the cutter 44.

[0030] In some specific embodiments, such as Figure 3As shown, in order to facilitate trimming of films of different widths, the adjusting component includes an inner motor 5, a screw 51 is rotatably connected inside the hollow column 41, the inner motor 5 is fixedly connected inside the hollow column 41, and is used to drive the screw 51 to rotate, symmetrical thread grooves are arranged on the outer sides of both ends of the screw 51, and feed blocks 52 are threadedly connected at both ends of the screw 51, and through grooves 45 are provided on the upper and lower sides of the hollow column 41, the feed block 52 passes through the through groove 45 and is connected to the corresponding outer motor 42, and the inner motor 5 is started to drive the screw 51 to rotate.

[0031] In some specific embodiments, such as Figure 2 As shown, in order to facilitate the rotation of the hollow column 41 to drive the driven gear 62 to rotate, the linkage assembly includes a driving gear 61, the driving gear 61 is fixedly connected to the outside of the hollow column 41, and the driven gear 62 is fixedly connected to the outside of the guide rod 6. The driving gear 61 is meshed with the driven gear 62. When the hollow column 41 rotates, the driving gear 61 is driven to rotate synchronously. The rotation of the driving gear 61 drives the driven gear 62 and the guide rod 6 to rotate in the opposite direction.

[0032] In some specific embodiments, such as Figure 2 or Figure 5 As shown, in order to ensure that the guide rod 6 does not affect the movable frame 63 when it rotates, through holes are opened on both side walls of the movable frame 63, and the guide rod 6 passes through the through holes without contacting the through holes. The guide rod 6 is in the shape of a cross rod, and the inner ring of the grinding block 65 is provided with a magnetic ring 66, and the inner side of the magnetic ring 66 is provided with a cross groove adapted to the guide rod 6, and the magnetic ring 66 slides along the outer wall of the guide rod 6 and can rotate with the guide rod 6.

[0033] In some specific embodiments, such as Figure 7 As shown, in order to facilitate the resetting of the grinding block 65, a rotating ring 64 is rotatably connected in the through hole, and a plurality of telescopic rods 7 are distributed between the rotating ring 64 and the grinding block 65 for limiting the position, and a spring 71 is also arranged between the rotating ring 64 and the grinding block 65 for resetting, one end of the spring 71 is connected to the grinding block 65, and the other end is connected to the rotating ring 64. In the absence of external force, the spring 71 pulls the grinding block 65 close to the inner wall of the movable frame 63, so that the grinding block 65 is away from the cutter 44.

[0034] In some specific embodiments, such as Figure 6As shown, in order to facilitate the grinding block 65 to approach the cutter 44, the driving assembly includes an electromagnet 72, and the electromagnet 72 cooperates with the magnetic ring 66. The two inner walls of the movable frame 63 are provided with electromagnets 72. A connecting wire 73 is connected to the electromagnet 72, and the other end of the connecting wire 73 is connected to an external power supply. When the electromagnet 72 is energized, the electromagnet 72 generates a repulsive force on the magnetic ring 66 of the same level, so that the grinding block 65 fits the cutter 44.

[0035] In some specific embodiments, such as Figure 6 As shown, in order to facilitate automatic stopping and cutting off of the circuit, a thermal bimetallic strip 74 is provided between the electromagnet 72 and the external power supply. Current is continuously transmitted to the thermal bimetallic strip 74, so that the temperature of the thermal bimetallic strip 74 is continuously increased. The working principle of the thermal bimetallic strip 74 is to utilize the different thermal expansion coefficients of two metals to produce bending deformation when the temperature changes, thereby controlling the on and off of the circuit.

[0036] In some specific embodiments, such as Figure 5 or Figure 6 As shown, in order to facilitate the cleaning of the cutter 44, the cleaning assembly includes a U-shaped frame 81, a mounting rod 8 is fixed to the side of the U-shaped frame 81, the U-shaped frame 81 is detachably connected to the movable frame 63 through the mounting rod 8, a cleaning block 82 is arranged inside the U-shaped frame 81, the cleaning block 82 is in contact with the cutter 44, and the mounting frame 4 rotates while the cleaning block 82 contacts the surface of the cutter 44 to clean the residual dust and impurities on the surface of the cutter 44, so that the cutter 44 is always kept clean during the cutting process and the sharpness of the blade is maintained.

[0037] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0038] In actual use, the coating device 3 is first used to coat the glass, and the coated glass panel is transported and moved by the conveying component 2. During the transportation process, the hollow column 41 is driven to rotate by the external motor 42, and the rotation of the hollow column 41 drives the cutter 44 to rotate to cut the excess film on both sides of the glass panel. Before use, the internal motor 5 is started to drive the screw 51 to rotate. While the screw 51 rotates, it drives the feeding blocks 52 on both sides to move toward each other. The feeding block 52 can drive the external motor 42 and the cutter 44 to move synchronously, and can adjust the distance between the two cutters 44, so that films of different widths can be cut, which has strong applicability. In the process of the feeding block 52 moving, the moving frame 63 moves with it, so as to ensure that the grinding block 65 is always on both sides of the cutter 44, and then the electromagnet 72 is energized, and the electromagnet 72 generates a repulsive force on the magnetic ring 66, so that the grinding blocks 65 on both sides clamp the outer edge of the cutter 44;

[0039] During use, the hollow column 41 can drive the driving gear 61 to rotate while rotating, so that the driven gear 62 meshing with the driving gear 61 can drive the guide rod 6 to rotate, and the rotation of the guide rod 6 can drive the grinding block 65 to rotate accordingly, so that the grinding block 65 can grind the cutter 44, so that the cutter 44 can maintain sufficient sharpness during trimming. As the current is continuously transmitted to the thermal bimetallic strip 74, the temperature of the thermal bimetallic strip 74 continues to increase. When the temperature reaches the specific thermal expansion "critical point" of the thermal bimetallic strip 74, the current path is disconnected, and then the electromagnet 72 no longer forms a magnetic field and exerts pressure on the magnetic ring 6. 6 is repelled, and due to the resilience of the spring 71, the magnetic ring 66 moves with the grinding block 65 toward one end of the inner wall of the movable frame 63, and returns to a state of not fitting with the cutter 44, thereby stopping the grinding of the cutter 44 to prevent long-term grinding from affecting the service life of the cutter 44. The cutter 44 is automatically ground each time the device is turned on, and automatically stops after grinding, without manual inspection each time, which is convenient for use. While the cutter 44 rotates, the cleaning block 82 contacts the surface of the cutter 44 to clean the residual dust and impurities on the surface of the cutter 44, so that the cutter 44 is always kept clean during the cutting process and the sharpness of the blade is maintained.

[0040] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
