Description

Technical Field

[0001] This application relates to the field of cutting mechanisms, and more particularly to a film edge cutting mechanism. Background Technology

[0002] Thin film materials, as key basic materials in modern industry, are widely used in fields such as electronics and electrical engineering. Especially in electrical engineering, insulating films are needed to enhance the insulation performance and safety of electrical equipment. When applying thin film materials, the edges are usually trimmed to fit different usage requirements.

[0003] Chinese utility model patent CN214081718U discloses a precise slitting mechanism for anti-fog film cutting. The mechanism includes a machine body, a feed roller, a tension roller, and a cutting roller sequentially rotatably connected to the machine body along the anti-fog film conveying direction, and an adjustment component installed on the outside of the machine body for adjusting the lifting and lowering of the tension roller. The anti-fog film is unwound by the feed roller and passes under the tension roller. The adjustment component is manually rotated to change the lifting and lowering position of the tension roller, thereby changing the tension of the anti-fog film. Finally, the anti-fog film is cut at the cutting roller.

[0004] Regarding the aforementioned technologies, the inventors believe that during high-speed cutting, the film located at the cutting roller is prone to floating, resulting in uneven cutting. Therefore, another mechanism can be provided to improve the cutting quality of the film. Utility Model Content

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a film edge cutting mechanism. (Refer to...) Figure 1 A film edge cutting mechanism includes a main frame 1, a cutter roller 2 rotatably mounted on the main frame 1, a swing frame 3 oscillatingly mounted on the main frame 1, a cutting roller 4 rotatably mounted on the swing frame 3 and cooperating with the cutter roller 2, an oscillating assembly 5 mounted on the main frame 1 and driving the cutting roller 4 to cut the film on the cutter roller 2, and a drive assembly 6 driving the cutter roller 2 and the cutting roller 4 to rotate relative to each other. The cutting roller 4 and the cutter roller 2 are arranged sequentially along the film conveying direction.

[0031] Reference Figure 1 and Figure 2 The drive assembly 6 includes a first gear 61 mounted on one side of the cutter roller 2, a second gear 62 mounted on the cutting roller 4 and meshing with the first gear 61, and a drive motor 63 mounted on the main frame 1 and driving the cutter roller 2 to rotate. The drive motor 63 is mounted on one side of the main frame 1, and its output end is coaxially connected to the cutter roller 2. The second gear 62 on the cutting roller 4 and the first gear 61 on the cutter roller 2 are mounted on the same side and can mesh and rotate. When the drive motor 63 is started, the cutter roller 2 drives the first gear 61 to rotate, the first gear 61 drives the second gear 62 to rotate, and the second gear 62 drives the cutting roller 4 to rotate, thus realizing relative rotation between the cutter roller 2 and the cutting roller 4. Reference Figure 2 There are two swing frames 3, which are respectively installed on the inner walls of the two sides of the main frame 1. The swing frame 3 includes a swing seat 31 for rotatably mounting the cutting roller 4, a swing connecting rod 32 with one end connected to the swing seat 31 and the other end rotatably mounted on the main frame 1, and a hinge seat 33 for fixing the swing connecting rod 32 to the inner wall of the main frame 1. The swing seat 31 at the other end of the swing connecting rod 32 can rotate a certain arc about the hinge seat 33 under the action of gravity, so that the cutting roller 4 mounted on the swing seat 31 always has a tendency to disengage from the cutter head roller 2.

[0032] Reference Figure 2 and Figure 3 The swing base 31 includes a support base 311 mounted on the top of the swing connecting rod 32 and a swing cover plate 312 fixed to the top of the support base 311. A rotation hole is formed between the support base 311 and the swing cover plate 312 for the two ends of the cutting roller 4 to be rotatably mounted. The top surface of the support base 311 and the bottom surface of the swing cover plate 312 abut against each other on both sides of the rotation hole, and bolts are provided on the abutment surfaces to connect and fix the lower support base 311 and the upper swing cover plate 312.

[0033] Reference Figure 2There are two sets of oscillating components 5, which are respectively installed on the left and right inner sidewalls of the main frame 1 at the oscillating seat 31 facing the film feeding direction. The oscillating component 5 includes a mounting block 51 installed on the inner sidewall of the main frame 1 and an abutting screw 52 threadedly installed on the mounting block 51 and abutting the oscillating seat 31. The mounting block 51 has a horizontally arranged threaded through hole 511 with a threaded engagement with the abutting screw 52. Rotating the abutting screw 52 can push the oscillating seat 31 towards the cutter roller 2, so that the cutting roller 4 and the cutter roller 2 can rotate together; rotating the abutting screw 52 in the opposite direction, the cutter roller 2 in the oscillating seat 31 rotates away from the cutter roller 2 with the oscillating seat 31 as the center under the action of gravity, so that the cutting roller 4 and the cutter roller 2 are disengaged.

[0034] Reference Figure 1 and Figure 4 The cutting roller 4 is equipped with two cutting wheels 41, which are arranged on both sides of the film at the desired cutting points. Each cutting wheel 41 includes a locking ring 411 sleeved on the cutting roller 4 and an annular blade 413 mounted on the end of the locking ring 411. The locking ring 411 has a locking break, and a first locking portion 4111 and a second locking portion 4112 are formed on both sides of the locking break. The first locking portion 4111 has a first locking hole in the opposite direction to the second locking portion 4112, and a locking bolt 4113 is arranged in the first locking hole. The second locking portion 4112 has a second locking hole at the junction with the first locking hole, and a locking thread is arranged in the second locking hole. Rotating the locking bolt 4113 connects and fixes the first locking portion 4111 and the second locking portion 4112, allowing the locking ring 411 to be fixed on the cutting roller 4.

[0035] Reference Figure 1 and Figure 4 The locking ring 411 has an annular groove 4114 around its outer circumference at its end. An annular blade 413 is installed within the groove 4114, and an annular cutting edge 4131 is arranged around the outer circumference of the blade 413. The rotation of the cutting roller 4 drives the locking ring 411 to rotate, which in turn drives the annular blade 413 to rotate. This rotation of the annular cutting edge 4131 creates a stable cutting action. An annular elastic element 412 is provided on the outer side of the locking ring 411. Under its elastic action, the annular elastic element 412 always provides a force to tighten the locking ring 411 towards the cutting roller 4, making the installation of the cutting roller 41 on the cutting roller 4 more secure. In this embodiment, the annular elastic element 412 is a spring.

[0036] Reference Figure 1 and Figure 5The cutter roller 2 has two cutting seats 21 arranged one-to-one with the cutting wheel 41 and cooperating to cut. The cutting seat 21 has a support ring surface 211 for film bonding and a cutting surface 212 on the inner side of the support ring surface 211 for the annular blade 4131 to abut against. The annular blade 4131 pushes the film towards the cutting surface 212, and the cutting surface 212 and the annular blade 4131 abut against each other to form a shearing action, thus cutting the film. The cutting seat 21 has a locking countersunk hole 213 that penetrates the inner and outer surfaces, and a locking bolt 214 is threaded into the locking countersunk hole 213. When the locking bolt 214 is tightened, the nut of the locking bolt 214 sinks into the locking countersunk hole 213, and the end opposite to the nut abuts against the surface of the cutter roller 2, fixing the cutting seat 21 to the cutter roller 2.

[0037] Reference Figure 1 and Figure 5 The cutter roller 2 is also fitted with a support seat 22 for supporting the film between the two cutting seats 21. The axial radius of the support seat 22 is the same as that of the cutting seats 21, so that both the support seat 22 and the cutting seats 21 can fit against the film and push the film towards the cutting roller 4, making the film taut and flat.

[0038] Reference Figures 1 to 5 The implementation principle of a film edge cutting mechanism according to an embodiment of this application is as follows: two cutting seats 21 are respectively installed on the blade roller 2, and two cutting wheels 41 are installed on the cutting roller 4; both ends of the cutting roller 4 are installed on the swing seat 31, and the swing assembly 5 is adjusted so that the second gear 62 on the cutting roller 4 meshes with the first gear 61; the positions of the cutting wheel 41, the cutting seat 21 and the support seat 22 are adjusted so that the required cutting positions at both ends of the film correspond to the cutting wheel 41 and the cutting seat 21 respectively, and the support seat 22 abuts against the film; the drive motor 63 is started to drive the blade roller 2 to rotate, the blade roller 2 drives the first gear 61 to rotate, the first gear 61 drives the second gear 62 to rotate, the second gear 62 drives the cutting roller 4 to rotate, and the cutting seat 21 on the blade roller 2 and the cutting wheel 41 on the cutting roller 4 rotate relative to each other to realize the edge cutting of the film.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
