[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] The embodiment of the utility model provides a film cutting mechanism 100 .

[0030] See also Figure 1 In one embodiment of the present invention, the film cutting mechanism 100 comprises:

[0031] Base 110;

[0032] A support assembly 120, the support assembly 120 includes a first support member 121, a first driving member 122, and a second driving member 123, the first driving member 122 is connected to the base 110; the second driving member 123 is connected to the first support rod;

[0033] A cutting assembly 130, the cutting assembly 130 comprising a mounting plate 131 connected to the second driving member 123 and a plurality of cutting blades 132 for cutting a film, wherein the plurality of cutting blades 132 are spaced apart and arranged on the mounting plate 131;

[0034] The second driving member 123 drives the cutting assembly 130 to move toward the direction close to the film so that the cutting member 132 contacts the film; the first driving member 122 drives the support rod to move in the cutting direction of the film so that the cutting member 132 cuts the film.

[0035] It can be understood that the technical solution of this embodiment is that a plurality of cutting pieces 132 are arranged on the mounting plate 131, and the second driving piece 123 is connected to the cutting assembly 130. Under the driving action of the second driving piece 123, the cutting assembly 130 can move as a whole in the direction close to the film, thereby driving the cutting piece 132 in the cutting assembly 130 to contact and cut the film. Then the first driving piece 122 is connected to the first supporting piece 121. When the first driving piece 122 drives the first supporting piece 121, the first supporting piece 121 drives the cutting assembly 130 to move in the cutting direction of the film through the second driving piece 123, so that the cutting piece 132 in the cutting assembly 130 cuts the film, and the automatic cutting of the film is completed. The above embodiment can replace manual cutting to improve production efficiency.

[0036] Furthermore, the plurality of cutting blades 122 are rotatably connected to the mounting plate 131 so that the cutting angle of the cutting blades 122 relative to the film can be adjusted to adapt to cutting films of different thicknesses.

[0037] Specifically, see Figure 1, the base 110 is usually installed on equipment such as a film winder that requires repeated cutting of the film. The first driving member 122 can be a cylinder or a crank slider mechanism. Specifically, in one embodiment, the cylinder body is fixedly connected to the base 110, the piston rod of the cylinder is connected to the first support member 121, and drives the first support member 121 to move. The second driving member 123 can be a cylinder or a crank slider mechanism. Specifically, in one embodiment, the cylinder body is fixedly connected to the first support member 121, the piston rod of the cylinder is connected to the cutting assembly 130, and drives the cutting assembly 130 to move.

[0038] Optionally, the movement speed of the second driving member 123 can be adjusted, so that the force of the cutter member in cutting the film in a direction close to the film can be adjusted, and the film cutting mechanism 100 is adapted to cutting films of different thicknesses.

[0039] See also Figure 2 On the basis of the above embodiment, the mounting plate 131 is provided with a fixing member 1311 , and the fixing member 1311 protrudes out of the mounting plate 131 and is hinged to the cutting member 132 .

[0040] It can be understood that the cutter 132 is hinged to the fixing member 1311, so that the cutter 132 can adjust the inclination angle of the cutter 132 relative to the film when cutting films of different types or thicknesses, so that the cutter 132 can adapt to the cutting of various types of films. The fixing member is protruding toward the direction close to the film cutting, one end of the cutter 132 is hinged to the fixing member, and the other end of the cutter is fixed to the mounting plate. The setting of the fixing member makes the end of the cutter 132 close to the film more stable; at the same time, it reduces the weight of the installation, reduces energy consumption, and makes the mechanism run lightly and smoothly.

[0041] Optionally, the fixing member 1311 is protruding from the mounting plate 131 and is welded or integrally formed with the mounting plate 131 .

[0042] See also Figure 1 In a preferred embodiment, the cutting assembly 130 further includes an adjusting link 133 , and the plurality of cutting blades 132 are hingedly connected to the adjusting link 133 , and the adjusting link 133 is movably mounted on the mounting plate 131 .

[0043] It can be understood that when the adjustment link 133 is hinged to the multiple cutting pieces 132, the inclination angle of the multiple cutting pieces 132 relative to the film can be adjusted by simply adjusting the relative position of the adjustment link 133 and the mounting plate 131, thereby improving the efficiency of angle adjustment of the cutting pieces 132.

[0044] See also Figure 2 Further, the adjusting link 133 has a first waist-shaped hole 133a, and the mounting plate 131 has a second waist-shaped hole 131a, and the first waist-shaped hole 133a and the second waist-shaped hole 131a are arranged to intersect.

[0045] Generally, bolts can be used to pass through the first waist-shaped hole 133a and the second waist-shaped hole 131a, and the bolts and nuts are used to fix the relative position of the adjustment connecting rod 133 and the mounting plate 131. Specifically, the first waist-shaped hole 133a is set to adjust the horizontal position of the adjustment connecting rod 133 relative to the mounting plate 131; the second waist-shaped hole 131a is set to adjust the vertical position of the adjustment connecting rod 133 relative to the mounting plate 131, thereby driving the cutting member 132 to rotate around the hinge point with the fixing member 1311 and fix it.

[0046] It can be understood that the extending direction of the mounting plate 131 is the horizontal direction, and the direction in which the mounting plate is close to the film is the vertical direction of the mounting plate.

[0047] Please continue reading Figure 2 In a preferred embodiment, the cutting blade 132 includes a blade holder 1325 and a blade 1326. The blade 1326 is fixed to the blade holder 1325, and the blade holder 1325 is connected to the mounting plate 131. It can be understood that the blade 1326 is a consumable material. The blade 1326 and the blade holder 1325 are separately provided, so that the blade 1326 can be easily replaced, so that the film cutting mechanism 100 can exert its maximum performance.

[0048] See also Figure 3 In a more specific embodiment, the support assembly 120 further includes a second support member 124 fixedly connected to the base 110, the second support member 124 has a slide groove 124a, and the first support member 121 is provided with a slider 1211 that slidably cooperates with the slide groove 124a. It can be understood that the cooperation between the slider 1211 and the slide groove 124a improves the stability of the movement of the first support member 121, making the mechanism run more smoothly.

[0049] Optionally, the sliding block 1211 and the first supporting member 121 are welded or integrally formed.

[0050] Optionally, the slide groove 124a is a through hole or a groove. Figure 3 In this embodiment, the slide groove 124a is a through hole.

[0051] See also Figure 1In a specific embodiment, one end of the first support member 121 away from the first driving member 122 is movably connected to the base 110 via a sleeve 125. Optionally, one end of the first support member 121 away from the first driving member 122 is a shaft body, and a rolling body is provided in the sleeve 125. The shaft body cooperates with the sleeve 125 through rolling sports to reduce friction between the shaft body and the sleeve 125.
