DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution: an automobile film cutting device, comprising a placing plate 1, the four corners of the bottom of the placing plate 1 are fixedly connected to a base 2, the front and rear sides of the placing plate 1 are provided with a first slide groove 3, the top of the placing plate 1 is slidably connected to a sliding seat 4, the top of the sliding seat 4 is rotatably connected to a fixing mechanism 5, the fixing mechanism 5 is fixedly connected to a cutting mechanism 6, the top left side of the placing plate 1 is fixedly connected to a fixing rod 7, and the surface of the fixing rod 7 is slidably connected to a clamping plate 8;

[0024] The top surface of the placement plate 1 is provided with scale marks, the bottom of the sliding seat 4 is slidably connected to the inside of the first slide groove 3, the bottom of the fixing rod 7 is attached to the top of the placement plate 1, and the top of the sliding seat 4 is provided with a rectangular opening.

[0025] Further, the fixing mechanism 5 includes a rotating seat 511, the rear end of the rotating seat 511 is rotatably connected to the top of the rear side of the sliding seat 4, a second sliding groove 512 is opened in the middle of the rotating seat 511, a sliding rod 513 is fixedly connected to the bottom of the rotating seat 511, and sliding blocks 514 are slidably connected to the front and rear sides of the sliding rod 513. Springs 515 are arranged on the front and rear sides of the sliding rod 513, a connecting rod 516 is rotatably connected to the bottom of the sliding block 514, and a pressing plate 517 is rotatably connected to the bottom end of the connecting rod 516, and an extension plate 518 is fixedly connected to the left and right sides of the top of the rotating seat 511;

[0026] The rotating seat 511 fits inside the rectangular opening at the top of the sliding seat 4, the bottom of the extension plate 518 fits against the top of the sliding seat 4, and strip sliding grooves are opened on the left and right sides of the second sliding groove 512. There are two sliding rods 513, and the two sliding rods 513 are symmetrically fixedly connected to the bottom of the sliding seat 4. One end of the spring 515 is fixedly connected to the outside of the slider 514, and the other end of the spring 515 is fixedly connected to the outer end of the sliding rod 513. A rubber gasket is arranged at the bottom of the pressure plate 517.

[0027] It should be noted that before cutting, by rotating the rotating seat 511, the rotating seat 511 is fitted into the rectangular opening at the top of the sliding seat 4. Under the limitation of the extension plate 518, the bottom of the cutting mechanism 6 is fitted on the top of the vehicle film. Before the cutting mechanism 6 contacts the vehicle film, the pressure plate 517 will first contact the vehicle film. When the pressure plate 517 contacts the vehicle film, the top connecting rod 516 rotates, driving the slider 514 to move along the outside of the slide rod 513, and at the same time squeezing the spring 515. The elastic force released by the spring 515 reacts back on the pressure plate 517, fixing the pressure plate 517 on the left and right sides of the vehicle film cutting position. The rubber gasket arranged at the bottom of the pressure plate 517 can not only increase the fixing effect of the pressure plate 517, but also prevent the pressure plate 517 from scratching the vehicle film when fixed, which is convenient for subsequent cutting.

[0028] Furthermore, the cutting mechanism 6 includes a threaded rod 611, the front and rear ends of the threaded rod 611 are rotatably connected to the inside of the second slide groove 512, the surface of the threaded rod 611 is threadedly connected to a threaded block 612, the bottom of the threaded block 612 is fixedly connected to a blade 613 by screws, the front end of the threaded rod 611 is fixedly connected to a servo motor 614, the front side of the servo motor 614 is fixedly connected to a fixing seat 615, and the front side of the fixing seat 615 is fixedly connected to a handle 616;

[0029] The threaded block 612 is provided with protrusions on the left and right sides, and the threaded block 612 is slidably connected to the inside of the second slide groove 512 through the protrusions on the left and right sides. The front end of the fixed seat 615 is fixedly connected to the front side of the rotating seat 511, and the bottom of the blade 613 is attached to the top of the placement plate 1.

[0030] It should be noted that during cutting, due to the limitation of the extension plate 518, the bottom end of the blade 613 can be attached to the top of the placement plate 1, and the servo motor 614 is started. Under the fixation of the fixing seat 615, the servo motor 614 drives the threaded rod 611 to rotate. When the threaded rod 611 rotates, due to the thread groove design in the middle of the thread block 612 and the limitation of the second slide groove 512 on the thread block 612, the blade 613 can move back and forth along the threaded rod 611, thereby driving the blade 613 to cut the fixed car film, and at the same time achieving automated cutting, the cutting accuracy can be guaranteed.

[0031] Working principle: When cutting, by holding the handle 616, rotate the fixing mechanism 5 and the cutting mechanism 6, release the contact between the blade 613 and the placement plate 1, unfold the car film roll and place it on the top of the placement plate 1, pull the clamping plate 8 upwards, place one end of the car film under the clamping plate 8, and after loosening the clamping plate 8, clamp one end of the car film between the placement plate 1 and the clamping plate 8, measure the car film through the scale marks on the surface of the placement plate 1, slide the sliding seat 4 to the cutting line, and then hold the handle 616 to rotate the rotating seat 511, fit the rotating seat 511 into the rectangular opening at the top of the sliding seat 4, and under the limit of the extension plate 518, make the bottom of the cutting mechanism 6 fit on the top of the car film, and before the cutting mechanism 6 contacts the car film, the pressing plate 517 will first contact the car film. When the pressing plate 517 contacts the car film, the top connecting rod 516 rotates, driving the slider 514 to move along the outside of the slide rod 513, and at the same time, the spring 515 is squeezed, and the elastic force released by the spring 515 reacts back on the pressure plate 517 to fix the pressure plate 517 on the left and right sides of the vehicle film cutting position. The rubber gasket arranged at the bottom of the pressure plate 517 can not only increase the fixing effect of the pressure plate 517, but also prevent the pressure plate 517 from scratching the vehicle film when fixed, which is convenient for subsequent cutting. When the extension plate 518 is limited, the bottom end of the blade 613 can be attached to the top of the placement plate 1, and the servo motor 614 is started. Under the fixation of the fixing seat 615, the servo motor 614 drives the threaded rod 611 to rotate. When the threaded rod 611 rotates, due to the thread groove design in the middle of the thread block 612 and the restriction of the second slide groove 512 on the thread block 612, the blade 613 can move back and forth along the threaded rod 611, thereby driving the blade 613 to cut the fixed vehicle film, while realizing automatic cutting, the cutting accuracy can be guaranteed.

[0032] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Simple modifications or equivalent substitutions of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
