[0052] like Figure 1-Figure 4 As shown, according to the first aspect of the embodiment of the present application, a cutting mechanism 100 is provided, including a mounting base 5, a first oblique member 3, a cutter assembly 1, a second oblique member 4 and a first driving assembly 2; the first oblique member 3 includes a first inclined surface 31; the first oblique member 3 is slidably connected to the mounting base 5, the second oblique member 4 includes a second inclined surface 41, the second inclined surface 41 is arranged at the end of the second oblique member 4 away from the mounting base 5, and the second inclined surface 41 abuts against the first inclined surface 31; the cutter assembly 1 is arranged on the side of the mounting base 5 away from the second oblique member 4, and the cutter assembly 1 is fixedly connected to the first oblique member 3; the second oblique member 4 is arranged at the driving end of the first driving assembly 2, the first driving assembly 2 can drive the second oblique member 4 to move along the X direction, the second inclined surface 41 moves along the X direction relative to the first inclined surface 31, and the cutter assembly 1 moves along the Z direction.

[0053] The cutting mechanism 100 in the embodiment of the present application can cut the edges of the film located on the surface of the roller.

[0054] like Figure 1 and Figure 2 As shown, the cutting mechanism 100 includes a mounting base 5, a first oblique member 3, a cutter assembly 1, a second oblique member 4 and a first driving assembly 2; wherein the cutter assembly 1 is used for cutting the film on the roller surface.

[0055] Further description, the first oblique member 3 includes a first inclined surface 31, the first oblique member 3 is fixedly connected to the cutter assembly 1, and the first inclined surface 31 is located on the side of the first oblique member 3 away from the cutter assembly 1; the second oblique member 4 is slidably connected to the mounting base 5, that is, the second oblique member 4 can move along the X direction relative to the mounting base 5; the second oblique member 4 includes a second inclined surface 41, and the second inclined surface 41 is located at one end of the second oblique member 4 away from the mounting base 5. The second oblique member 4 is arranged at the driving end of the first driving assembly 2, and the first driving assembly 2 can drive the second oblique member 4 to move along the X direction. Therefore, the second oblique member 4 can slide along the X direction relative to the mounting base 5; the first inclined surface 31 abuts against the second inclined surface 41. Specifically, the first oblique member 3, the cutter assembly 1 and the second oblique member 4 are arranged along the Z direction; when the first driving assembly 2 drives the second oblique member 4 to move along the X direction, since the first inclined surface 31 abuts against the second inclined surface 41, the second inclined surface 41 will move along the X direction relative to the first inclined surface 31, and the first oblique member 3 will move along the Z direction, thereby causing the cutter assembly 1 to move along the Z direction, so that the distance between the cutter assembly 1 and the roller surface can be adjusted.

[0056] In the embodiment of the present application, the first inclined surface 31 of the first inclined member 3 abuts against the second inclined surface 41 of the second inclined member 4, and the second inclined member 4 is driven to move along the X direction to adjust the position of the cutter assembly 1 in the Z direction. The adjustment accuracy is high, and the cutter assembly 1 can be adjusted to a better position, thereby avoiding damage to the roller surface.

[0057] The first drive assembly 2 may be a linear motor, a cylinder or a hydraulic cylinder. Preferably, the first drive assembly 2 includes a servo motor and a screw, the screw is connected to the driving end of the servo motor, the servo motor can drive the screw to rotate around the axis of the X direction, and the second oblique member 4 is rotationally connected to the screw, so when the servo motor drives the screw to rotate, the second oblique member 4 will move relative to the screw in the X direction, so the servo motor controls the moving distance of the cutter assembly 1 in the Z direction by driving the speed of the screw or the number of revolutions, and its adjustment accuracy is relatively high.

[0058] Further explanation: the second oblique member 4 is slidably connected to the mounting base 5, and a guide rail is provided on the mounting base 5, and the length direction of the guide rail is the same as the X direction. A slider is provided on the second oblique member 4, and the slider is slidably connected to the guide rail, thereby realizing the sliding connection between the second oblique member 4 and the mounting base 5. When the second oblique member 4 moves along the X direction, the guide rail can provide a guiding function for the second oblique member 4 to prevent the second oblique member 4 from being deflected.

[0059] like Figure 2As shown, in an optional embodiment, the inclination direction of the first inclined surface 31 is opposite to the inclination direction of the second inclined surface 41. When the first inclined surface 31 abuts against the second inclined surface 41, the first inclined surface 31 and the second inclined surface 41 can overlap each other, thereby improving the stability between the first oblique member 3 and the second oblique member 4.

[0060] In an optional embodiment, the cutter assembly 1 includes a first mounting frame 11 and a second mounting frame 12, the first oblique member 3 is arranged on the first mounting frame 11, and the first mounting frame 11 is connected to the second mounting frame 12; the cutting mechanism 100 also includes a mounting base 5, the first driving assembly 2 is arranged on the mounting base 5, and a first elastic member 13 is arranged between the second mounting frame 12 and the mounting base 5.

In this embodiment, in the Z direction, the first oblique member 3 is located above the second oblique member 4, and when the cutter assembly 1 is adjusted, the first drive assembly 2 can provide support for the cutter assembly 1, and can improve the installation stability of the cutter assembly 1.

[0062] like Figure 1 and Figure 3 As shown, the cutter assembly 1 also includes a second mounting frame 12, and the second mounting frame 12 is connected to the second mounting plate 112 and the third mounting plate 113 at one end away from the first mounting plate 111; the first driving assembly 2 is arranged on the mounting base 5, and in the Z direction, the second mounting frame 12 is located below the mounting base 5; a first elastic member 13 is arranged between the second mounting frame 12 and the mounting base 5, that is, one end of the first elastic member 13 is arranged on the second mounting frame 12, and the other end of the first elastic member 13 is arranged on the side of the mounting base 5 facing the second mounting frame 12, and the first elastic member 13 can increase the pressure between the first oblique member 3 and the second oblique member 4, so as to prevent the first oblique member 3 and the second oblique member 4 from detaching from each other, thereby improving the stability of the cutting mechanism 100.

[0063] To further explain, if the cutting mechanism 100 is rotated 180° for use, the first elastic member 13 can offset the gravity of the cutter assembly 1 to prevent the first oblique member 3 and the second oblique member 4 from being separated from each other due to gravity.

[0064] The first elastic member 13 may be a spring.

[0065] like Figure 3 As shown, in an optional embodiment, the cutter assembly 1 further includes a limit rod 14, which is disposed between the mounting base 5 and the second mounting frame 12, and the limit rod 14 can adjust the distance between the mounting base 5 and the second mounting frame 12.

[0066] In an optional embodiment, the cutter assembly 1 further includes a cutter portion 15, and the cutter portion 15 is connected to the second mounting frame 12.

The axial direction of the roller is the same as the Y direction, and the first drive member 153 drives the cutter 151 to rotate around the axis of the Y direction, that is, the rotation direction of the cutter 151 is the same as or opposite to the rotation direction of the roller, so by controlling the rotation direction and rotation speed of the cutter 151, the cutter 151 can cut the film on the roller surface.

[0067] like Figure 3 As shown, in an optional embodiment, the mounting seat 152 is provided with a transmission shaft, the axial direction of the transmission shaft is the same as the Y direction, and the cutter 151 is arranged on the transmission shaft; the first driving member 153 includes a motor 1534, a driving wheel 1531, a driven wheel 1532 and a transmission belt 1533, the driven wheel 1532 is arranged on the transmission shaft, the driving wheel 1531 is arranged at the output end of the motor 1534, and the transmission belt 1533 is sleeved on the driving wheel 1531 and the driven wheel 1532; the motor 1534 can drive the driving wheel 1531 to rotate, and the driven wheel 1532 can be driven to rotate through the transmission belt 1533. Since the driven wheel 1532 and the cutter 151 are both arranged on the transmission shaft, the cutter 151 will also rotate accordingly. The first driving member 153 in this embodiment has a simple structure, is easy to install, and has a low cost.

[0068] In an alternative embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the cutting mechanism 100 also includes a dust suction component 6, which is used to suck away the material cut by the cutter component 1; after the cutter component 1 cuts the edge of the film on the roller surface, the dust suction component 6 can suck away the cut edge material, thereby preventing the edge material from affecting other processes.

[0069] In an optional embodiment, the dust suction assembly 6 includes a working part 61 and a second driving member 62, the working part 61 is connected to the driving end of the second driving member 62, and the second driving member 62 can drive the working part 61 to move along the Z direction.

[0070] like Figure 1 , Figure 3 and Figure 4 As shown, the dust collection assembly 6 includes a working part 61 and a second driving part 62. The working part 61 is connected to the driving end of the second driving part 62. The second driving part 62 can drive the working part 61 to move along the Z direction, that is, the second driving part 62 can drive the working part 61 to move closer to or away from the roller surface, so as to adjust the positional relationship between the working part 61 and the roller surface.

[0071] Further explanation, the second driving member 62 is arranged on the cutter assembly 1, specifically, the second driving member 62 is arranged on the second mounting frame 12, so that the dust collection assembly 6 and the cutter assembly 1 can move as a whole; and the second driving member 62 can lift the working part 61 to above the highest point of the roller surface, so as to prevent the working part 61 from hitting the roller surface when the cutting mechanism 100 moves in the X direction.

[0072] The second driving member 62 may be a hydraulic cylinder, a pneumatic cylinder or a linear motor.

[0073] like Figure 4 As shown, in an optional embodiment, the working part 61 includes a third mounting frame 611 and a suction nozzle 612, and the suction nozzle 612 is arranged on the third mounting frame 611, and the suction nozzle 612 faces the roller surface.

[0074] like Figure 4 As shown, in an optional embodiment, the working part 61 also includes a scraper 613, and the scraper 613 is arranged at one end of the third mounting frame 611 facing the roller surface; when the cutter assembly 1 cuts the edge material of the membrane located on the roller surface, the scraper 613 can peel the cut edge material from the roller surface to facilitate the suction nozzle 612 to remove it.

When the working part 61 contacts the roller surface, the second elastic member 616 will play a buffering role to avoid rigid contact between the working part 61 and the roller surface and damage to the working part 61 or the roller surface.

[0078] The second elastic member 616 may be a spring.
