Detailed implementation manners

[0024] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] As Figures 1 - 3 shown, a cutting device of the present utility model includes

[0026] a cutting table 1, and a mounting frame 2 is fixedly installed on the upper surface of the cutting table 1;

[0027] a cylinder 3, the cylinder 3 is fixedly installed at the upper end of the mounting frame 2, the mounting frame 2 is a prior art, and a structure same as that of the cutting table 1 can be selected to realize stable installation of the cylinder 3. The telescopic end of the cylinder 3 passes through the mounting frame 2 and is fixedly installed with an assembly plate 4. A through groove 41 is horizontally opened at the front side of the top of the assembly plate 4, and sliding grooves 42 are symmetrically opened at the front and rear of the bottom of the assembly plate 4;

[0028] a leveling mechanism 5, the leveling mechanism 5 is slidably connected to the two sliding grooves 42 through two connecting blocks 57, and a first driving assembly 6 for driving the leveling mechanism 5 to move left and right is arranged inside one of the sliding grooves 42;

[0029] Specifically, the leveling mechanism 5 includes a mounting table 51, the mounting table 51 is fixedly installed on the left side of the bottom of the assembly plate 4, a leveling plate 52 is fixedly installed at the bottom of the mounting table 51, the lower ends of the two connecting blocks 57 are jointly fixedly installed with a mounting plate 53, elastic telescopic rods 54 are symmetrically installed on the lower side of the mounting plate 53 at the front and rear, the lower ends of the two elastic telescopic rods 54 are both fixedly installed with assembly blocks 55, and a pressing roller 56 is rotatably assembled on the side where the two assembly blocks 55 are close to each other.

[0030] Specifically, the first driving component 6 includes a first threaded rod 61. The left and right ends of the first threaded rod 61 are respectively rotatably connected to the left and right inner walls of the rear sliding groove 42. The rear connecting block 57 is threadedly connected to the first threaded rod 61. A first motor 62 is fixedly installed at the rear right side of the assembly plate 4. The output shaft of the first motor 62 is drivingly connected to the first threaded rod 61. The first motor 62 is electrically connected to the controller 9.

[0031] In the initial state, the air cylinder 3 drives the assembly plate 4 to move upward, and the installation table 51 is away from the cutting table 1. When it is necessary to cut the automotive protective film, place the automotive protective film on the top of the cutting table 1. Then start the air cylinder 3. The telescopic end of the air cylinder 3 drives the assembly plate 4 to move downward until the flattening plate 52 contacts the automotive protective film and applies pressure to press it. Then start the first motor 62 through the controller 9. The first motor 62 drives the first threaded rod 61 to rotate. Through the threaded connection between the rear connecting block 57 and the first threaded rod 61, drive the two connecting blocks 57 to move. The two connecting blocks 57 drive the pressing roller 56 to move. In the initial state, the lower side of the pressing roller 56 abuts against the upper side of the flattening plate 52. As the pressing roller 56 moves, the elastic telescopic rod 54 will stretch and contract, and then drive the pressing roller 56 to contact the automotive protective film and apply a pressing force. As the pressing roller 56 continuously pushes on the automotive protective film, the uneven parts of the automotive protective film can be flattened until the pressing roller 56 reaches the end of the automotive protective film, and then the movement of the pressing roller 56 can be stopped. In this way, the leveling work of the automotive protective film is completed. After leveling and cutting, the pressing roller 56 can be controlled to return to the initial position.

[0032] The cutting mechanism 7 is slidably assembled left and right inside the through groove 41. A second driving component 8 is provided inside the through groove 41 for driving the cutting mechanism 7 to move left and right. Specifically, the cutting mechanism 7 includes a moving block 71. The moving block 71 is slidably assembled inside the through groove 41. A central part of the top of the moving block 71 is fixedly installed with an electric telescopic rod 72. The telescopic end of the electric telescopic rod 72 passes through the moving block 71 and is fixedly installed with a cutting knife 73. The electric telescopic rod 72 is electrically connected to the controller 9.

[0033] Specifically, the second driving component 8 includes a second threaded rod 81. The left and right ends of the second threaded rod 81 are respectively rotatably connected to the left and right inner walls of the through groove 41. The moving block 71 is threadedly connected to the second threaded rod 81. A second motor 82 is fixedly installed on the left side of the assembly plate 4. The output shaft of the second motor 82 is drivingly connected to the second threaded rod 81. The second motor 82 is electrically connected to the controller 9.

[0034] In the initial state, the output shaft of the second motor 82 is drivingly connected to the second threaded rod 81 through a transmission. During use, by simply controlling the output shaft of the second motor 82 to rotate forward or backward through the controller 9, the moving block 71 can be driven to move through the threaded connection between the moving block 71 and the second threaded rod 81 to change the cutting position. When not cutting, the telescopic end of the electric telescopic rod 72 is in a contracted state. When cutting is required, only need to control the telescopic end of the electric telescopic rod 71 to extend downward until the automotive protective film is completely cut, and the operation is simple and convenient.

[0035] The controller 9 is fixedly installed on the front side of the mounting frame 2. The first drive assembly 6, the second drive assembly 8, the cylinder 3, and the cutting mechanism 7 are all electrically connected to the controller 9.

[0036] A scale line 43 is provided on the front side of the assembly plate 4.

[0037] The usage method of this device is as follows:

[0038] When the automotive protective film needs to be cut, place the automotive protective film to be cut on the tabletop of the cutting table 1. Then start the cylinder 3 through the controller 9. The telescopic end of the cylinder 3 drives the assembly plate 4 to move downward until the flattening plate 52 abuts against the upper side of the automotive protective film and applies a pressing force to press it tightly. Then start the first motor 62 to make the first motor 62 drive the first threaded rod 61 to rotate, and then drive the two connecting blocks 57 to move. The pressing roller 56 gradually moves and slides onto the upper side of the automotive protective film. The springs inside the two elastic telescopic rods 54 provide a pressing force. As the pressing roller 56 moves, the pressing roller 56 can flatten the uneven places of the automotive protective film until the pressing roller 56 moves to the end of the automotive protective film. The pressing roller 56 and the flattening plate 52 jointly apply a pressing force to prevent the automotive protective film from shifting. Then compare the scale line 43 to select the size of the automotive protective film to be cut. When adjusting, start the second motor 82 to make the second motor 82 drive the moving block 71 to move left and right. After moving to the appropriate position, control the telescopic end of the electric telescopic rod 72 to extend to drive the cutting knife 73 to cut the automotive protective film.
