[0020] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0021] See also Figure 1 and Figure 2The embodiment of the utility model discloses a floating film cutting device of a film cutting equipment, which includes a machine base 1, a lifting mechanism 2 and a knife sleeve mechanism 3. The machine base 1 fixes the lifting mechanism 2 and the knife sleeve mechanism 3, wherein the lifting mechanism 2 can drive the knife sleeve mechanism 3 to lift and lower. After the moving mechanism moves the lifting mechanism 2 and the knife sleeve mechanism 3 into place, the knife sleeve mechanism 3 needs to be lowered to the position of the plate film, and the lifting mechanism 2 can drive the knife sleeve mechanism 3 to lower. A knife adjusting mechanism 4 and a knife 31 are provided in the knife sleeve mechanism 3, and the knife 31 protrudes downward and can cut the film. The knife 31 is transmission-connected with the knife adjusting driving member 41 of the knife adjusting mechanism 4, and the knife adjusting driving member 41 can independently drive the knife 31 to lift and lower, so that the depth of the knife 31 inserted into the film can be adjusted to adapt to films of different thicknesses, thereby avoiding cutting too shallowly or scratching the plate. When in use, the lifting mechanism 2 can drive the knife adjusting mechanism 4 and the knife 31 of the knife sleeve mechanism 3 to descend to the position of the film at the same time, and the knife adjusting mechanism 4 can further adjust the lifting and lowering of the knife 31 independently to adapt to different film thicknesses. The knife adjusting mechanism 4 can use components such as high-precision drive motors, so it can achieve higher adjustment accuracy.

[0022] The beneficial effects of the embodiments of the present utility model are as follows:

[0023] The floating film cutting device of the thin film cutting equipment of the embodiment of the present utility model is provided with a machine base 1, a lifting mechanism 2 and a knife sleeve mechanism 3, wherein the lifting mechanism 2 is capable of driving the knife sleeve mechanism 3 to be raised and lowered, and the knife sleeve mechanism 3 is provided with a knife adjustment mechanism 4 and a knife 31, and the knife 31 is connected to the knife adjustment drive 41 of the knife adjustment mechanism 4 by transmission, and the knife adjustment drive 41 is capable of independently driving the knife 31 to be raised and lowered. When in use, the lifting mechanism 2 is capable of driving the knife adjustment mechanism 4 and the knife 31 of the knife sleeve mechanism 3 to be raised and lowered simultaneously, and the knife adjustment mechanism 4 is capable of independently further adjusting the raising and lowering of the knife 31. The knife adjustment mechanism 4 can use components such as a high-precision drive motor, and thus can achieve a high adjustment accuracy. Therefore, the utility model can not only be raised and lowered, but also independently adjust the height of the knife 31, and the adjustment accuracy is high.

[0024] Specifically, in order to connect the tool sleeve mechanism 3, the lifting mechanism 2 further includes a lifting seat 22. The tool sleeve mechanism 3 is connected within the lifting seat 22. The lifting seat 22 is in transmission connection with the lifting driving member 21. The lifting driving member 21 can drive the lifting seat 22 to vertically lift and lower, and the lifting seat 22 can drive the tool sleeve mechanism 3 to move. In order to drive the lifting seat 22 to lift and lower, the lifting mechanism 2 further includes a lifting lead screw 23. The lifting driving member 21 is in transmission connection with the lifting lead screw 23. The outer wall of the lifting lead screw 23 is provided with threads. The lifting lead screw 23 vertically passes through the lifting seat 22 and meshes with the threads within the lifting seat 22. The lifting driving member 21 can drive the lifting lead screw 23 to rotate. When the lifting lead screw 23 rotates, the lifting seat 22 can vertically lift and lower, thereby driving the lifting seat 22 to vertically lift and lower.

[0025] See Figure 2 , in order to connect the tool sleeve mechanism 3, a through hole 221 is provided within the lifting seat 22. A floating mechanism 5 is provided between the tool sleeve mechanism 3 and the lifting seat 22. The floating mechanism 5 includes a connecting seat 51. The connecting seat 51 passes through the through hole 221 and is connected to the tool sleeve mechanism 3. The tool sleeve mechanism 3 is fixed to the connecting seat 51. The connecting seat 51 is movably connected to the lifting seat 22. The connecting seat 51 can slightly move relative to the lifting seat 22, and the tool sleeve mechanism 3 can move following the connecting seat 51. For a plate with a not-high surface flatness, when the tool sleeve mechanism 3 moves, it may encounter concave pits or protrusions. If the tool sleeve mechanism 3 maintains its height at this time, it will cut the film too shallowly when encountering a concave pit and cut too deeply or even scratch the plate when encountering a protrusion. Therefore, in this case, the tool sleeve mechanism 3 can lift and lower to a certain extent relative to the lifting seat 22 to ensure that the tool sleeve mechanism 3 can descend when encountering a concave pit and ascend when encountering a protrusion to ensure the normal cutting depth.

[0026] The floating mechanism 5 further includes a supporting rod 52. A limiting boss 521 is provided at the bottom of the supporting rod 52. The limiting boss 521 protrudes from the side wall of the supporting rod 52 to form an inverted T shape. A sliding hole 511 is provided on the connecting seat 51. The supporting rod 52 passes upward through the sliding hole 511. The limiting boss 521 can support the edge side of the sliding hole 511, thereby forming a support for the connecting seat 51. The upper part of the supporting rod 52 is fixed to the lifting seat 22. In this way, the supporting rod 52 is fixedly connected to the lifting seat 22, and the sliding hole 511 can slide up and down along the supporting rod 52. Therefore, the connecting seat 51 can move upward relative to the supporting rod 52. The tool sleeve mechanism 3 is fixed to the connecting seat 51, so it can move up and down to a certain extent relative to the lifting seat 22.

[0027] For the normal operation of the tool sleeve mechanism 3 to enable the tool sleeve mechanism 3 to press down on the film, the floating mechanism 5 further includes an elastic member 53. One end of the elastic member 53 abuts against the bottom of the lifting seat 22, and the other end of the elastic member 53 abuts against the top of the connecting seat 51. During use, the lifting seat 22 drives the tool sleeve mechanism 3 to descend. The bottom of the tool sleeve mechanism 3 slightly presses on the film, and the elastic member 53 is in a compressed state. The tool 31 extends out of the bottom of the tool sleeve mechanism 3 to cut the film. During the cutting process, if a protrusion is encountered, the reaction force of the protrusion will cause the connecting seat 51 to move upward relative to the supporting rod 52, and the elastic member 53 is in a compressed state. If a pit is encountered, the elastic force of the elastic member 53 is used to cause the connecting seat 51 to descend to a certain extent.

[0028] Inside the tool sleeve mechanism 3, the tool sleeve mechanism 3 further includes a connecting rod 32. One end of the connecting rod 32 is movably connected to the tool adjusting driving member 41, and the other end of the connecting rod 32 is movably connected to the tool 31. The tool adjusting driving member 41 can drive the connecting rod 32 to move vertically up and down to drive the tool 31 to move up and down, thereby realizing the function of adjusting the height of the tool 31.

[0029] See Figure 3, in order to connect the tool setting driving member 41, the connecting rod 32 and the tool 31, the tool sleeve mechanism 3 further includes a magnetic member 33. The magnetic member 33 is magnetically connected to the connecting rod 32, and the magnetic member 33 endows the connecting rod 32 with magnetism. One end of the connecting rod 32 is magnetically connected to the movable end of the tool setting driving member 41, and the other end of the connecting rod 32 is magnetically connected to the tool 31. Being connected by magnetic force can not only keep the connection between the tool 31 and the connecting rod 32 with the tool setting driving member 41, but also enable the tool 31 to obtain the freedom of rotation, so that when the lifting mechanism 2 turns, the film can drive the tool 31 to rotate adaptively.

[0030] The tool sleeve mechanism 3 further includes a tool sleeve main body 34 and a tool cap 35. The tool cap 35 covers the bottom of the tool sleeve mechanism 3, and the tool 31 can pass through the tool cap 35. The tool cap 35 can press on the surface of the film, so as to facilitate the tool 31 to cut the film near the tool cap 35.

[0031] The embodiment of the present invention also discloses a film cutting device (not shown in the drawings), including the floating film cutting device of the film cutting device as described above. The film cutting device can drive the tool sleeve mechanism 3 to lift by the lifting mechanism 2, and when tool setting is required, the tool setting driving member 41 of the tool setting mechanism 4 is used to drive the tool 31 to adjust the height. The tool setting mechanism 4 can use components such as a driving motor with high precision, so high adjustment precision can be achieved. Therefore, the film cutting device of the present invention can not only control the overall lifting of the tool 31, but also individually adjust the height of the tool 31, and the adjustment precision is high.

[0032] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
