Description

Technical Field

[0001] The present application relates to the field of film production technology, and in particular to a film edge cutting device. Background Art

[0002] Film is a thin, soft, transparent sheet made of plastic, adhesive, rubber or other materials. It is widely used in electronics, machinery, printing and other industries.

[0003] Currently, after film production is completed, it needs to be wound up using a winding device. Before winding, the film is cut by a cutting device, and then the film is transported to the winding roller for winding. The conveyor roller swings significantly when transporting the film, which evens out the thickness of the film, improves the flatness of the wound film, and reduces the possibility of ribs and dents in the wound film. However, when winding the film, due to the very close adhesion between the films, the films are prone to local adhesion, making it difficult to expel air when winding the film, resulting in adhesion and bulging, which in turn affects the final winding effect. Utility Model Content

[0004] In order to improve the film winding effect, the present application provides a film edge cutting device.

[0005] The film edge cutting device provided in this application adopts the following technical solution:

[0006] A film edge cutting device includes a support, a cutting mechanism and a driving mechanism. The support is provided on each side of the winding device. The cutting mechanism is slidably provided on the support and is used to cut the edge of the film. The driving mechanism is provided on the support and is used to drive the two cutting mechanisms to move back and forth.

[0007] By adopting the above technical solution, when winding the film, the driving mechanism drives the two cutting mechanisms to move back and forth on the support, so that the two cutting mechanisms can cut the two edges of the film unevenly when cutting the film, so that more air can enter between the films, improving the problem of easy adhesion between the films. When the winding roller subsequently winds the film, the air is expelled, so that the film can be wound smoothly, effectively improving the winding effect of the film.

[0008] Optionally, the cutting mechanism includes a base, a cutter and a locking member, the base is slidably arranged on the support, the cutter is slidably inserted on the base, and the locking member is arranged on the base and is used to lock the cutter on the base.

[0009] By adopting the above technical solution, the staff drives the cutter to slide on the base so that the cutter is close to the film, and then locks the cutter on the base through the locking piece. When the conveyor roller conveys the film, the cutter can cut the edge of the film, and the staff can easily adjust the distance between the cutter and the film, thereby improving the applicability of the cutter to the cutting needs of different films.

[0010] Optionally, the locking member includes a locking bolt, the locking bolt thread is provided on the base, and the locking bolt is pressed against the cutter.

[0011] By adopting the above technical solution, the staff turns the locking bolt so that the locking bolt is close to the base, and the locking bolt can press the cutter against the base, thereby locking the cutter on the base.

[0012] Optionally, a plurality of balls are rotatably provided on the base, and the plurality of balls are all in contact with the support.

[0013] By adopting the above technical solution, the ball bearings reduce the friction between the base and the support, making it easier for the base to slide on the support.

[0014] Optionally, the driving mechanism includes a driving motor, a cam, a driving rod, a connecting rod and a locking piece, the driving motor is arranged on a support, the cam is eccentrically arranged on the output shaft of the driving motor, the driving rod is rotatably sleeved on the cam, the connecting rod is rotatably arranged on the driving rod, and the locking piece is arranged on the connecting rod and is used to lock the connecting rod to the two bases.

[0015] By adopting the above technical solution, the staff locks the connecting rod to the two bases through the locking piece, and then starts the drive motor. The output shaft of the drive motor drives the cam to rotate eccentrically. As the cam rotates back and forth, the cam pulls the drive rod, causing the drive rod to reciprocate close to or away from the drive motor. The drive rod then pulls the connecting rod, causing the connecting rod to move back and forth. The connecting rod can simultaneously drive the two bases to move back and forth, and the base then drives the cutter to move back and forth, thereby improving the convenience of driving the two cutters to move back and forth at the same time.

[0016] Optionally, two baffles are spaced apart on the cam, and the two baffles are respectively located on both sides of the driving rod.

[0017] By adopting the above technical solution, the two baffles limit the driving rod, effectively improving the stability of the driving rod's rotational connection to the cam.

[0018] Optionally, the locking member includes a locking bolt, which is slidably passed through the connecting rod and threadedly connected to the base.

[0019] By adopting the above technical solution, the staff turns the locking bolt so that the locking bolt approaches the connecting rod and presses against the connecting rod, and the locking bolt can lock the connecting rod and the base.

[0020] Optionally, a bar hole is provided on the connecting rod along the sliding direction of the base, and the locking bolt is slidably inserted into the bar hole.

[0021] By adopting the above technical solution, the staff can turn the locking bolt to move the locking bolt away from the connecting rod, drive the base to slide on the support, and quickly and conveniently adjust the position of the cutter along the width and length of the film. Then, turn the locking bolt in the opposite direction so that the locking bolt presses the connecting rod and the base tightly, thereby adjusting the connection position of the connecting rod and the base.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. Allow more air to enter between the films, improve the problem of easy adhesion between the films, and then when the winding roller rewinds the film, the air will be expelled, so that the film can be rolled flat, effectively improving the film rolling effect;

[0024] 2. When the conveyor roller conveys the film, the cutter can cut the edge of the film, and the staff can easily adjust the distance between the cutter and the film, improving the applicability of the cutter to the cutting needs of different films;

[0025] 3. The cam pulls the driving rod, causing the driving rod to reciprocate towards or away from the driving motor. The driving rod then pulls the connecting rod, causing the connecting rod to reciprocate. The connecting rod can simultaneously drive the two bases to reciprocate, and the bases then drive the cutters to reciprocate, thereby improving the convenience of driving the two cutters to reciprocate at the same time.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-2This application is described in further detail.

[0030] The embodiment of the present application discloses a film edge cutting device.

[0031] Reference Figure 1 The film edge cutting device includes a support 1, a cutting mechanism 2 and a driving mechanism 3. A support 1 is installed on each side of the winding device. A cutting mechanism 2 is installed on one support 1 for sliding along the width direction of the film. The two cutting mechanisms 2 are respectively used to cut the two edges of the film. The driving mechanism 3 is installed on the support 1 and is used to drive the two cutting mechanisms 2 to slide.

[0032] When the winding device is winding the film, the driving mechanism 3 drives the two cutting mechanisms 2 to slide along the width direction of the film. The two cutting mechanisms 2 can cut the two edges of the film unevenly, thereby allowing space between the films to allow more air to enter, reducing the problem of the films easily adhering to each other. When the winding roller of the subsequent winding device winds up the film, the air between the two films is expelled as the winding roller squeezes, so that the film can be wound flatly, improving the situation where air remains between the two films and causes adhesion and bulging, and effectively improving the winding effect of the film.

[0033] Reference Figure 1 、 Figure 2 The cutting mechanism 2 includes a base 21, a cutter 22 and a locking member 23. The base 21 is slidably mounted on the support 1. In this embodiment, a guide rail is installed on the support 1 along the width direction of the film, and the base 21 is slidably mounted on the guide rail. The guide rail guides the sliding of the base 21, thereby improving the stability of the base 21 sliding along the width direction of the film; and a plurality of balls 4 are rotatably mounted on the base 21, and the plurality of balls 4 are respectively abutted against the guide rails. The plurality of balls 4 reduce the friction between the base 21 and the guide rails, thereby improving the smoothness of the base 21 sliding on the support 1.

[0034] Reference Figure 1 、 Figure 2 The cutter 22 is slidably inserted into the base 21 in the direction toward the film, and the locking member 23 is installed on the base 21. The locking member 23 is used to lock the cutter 22 on the base 21. The locking member 23 includes a locking bolt 231. The locking bolt 231 is threadedly installed on the base 21, and the locking bolt 231 extends to press against the cutter 22.

[0035] The staff drives the cutter 22 to move in the direction close to the film, so that the cutter 22 is close to the film, and then turns the locking bolt 231 so that the locking bolt 231 is close to the base 21. The locking bolt 231 can be tightened to the cutter 22, and then the cutter 22 is pressed against the base 21, and the cutter 22 is locked on the base 21. As the conveyor roller conveys the film, the cutter 22 can cut the edge of the film; the staff turns the locking bolt 231 so that the locking bolt 231 is away from the cutter 22, and then drives the cutter 22 to slide on the base 21 in the direction toward the film, and then locks the cutter 22 on the base 21. The distance between the cutter 22 and the film can be adjusted, thereby improving the applicability of the cutter 22 to the cutting needs of different films.

[0036] Reference Figure 1 、 Figure 2 The driving mechanism 3 includes a driving motor 31, a cam 32, a driving rod 33, a connecting rod 34 and a locking member 35. The driving motor 31 is mounted on the support 1, and the cam 32 is eccentrically mounted on the output shaft of the driving motor 31. The driving rod 33 is rotatably sleeved on the cam 32. Two baffles 5 are installed on the cam 32 at intervals. The two baffles 5 are respectively located on both sides of the driving rod 33. The two baffles 5 limit the position of the driving rod 33 sleeved on the cam 32, so that the driving rod 33 can only rotate on the cam 32 as the cam 32 rotates eccentrically, reducing the possibility of the driving rod 33 slipping off the cam 32 and improving the stability of the driving rod 33 on the cam 32.

[0037] Reference Figure 1 、 Figure 2 The connecting rod 34 is rotatably mounted on the driving rod 33, and the locking piece 35 is mounted on the connecting rod 34. The locking piece 35 is used to lock the connecting rod 34 on the two bases 21. The locking piece 35 includes a locking bolt 351. A bar hole 341 is opened on the connecting rod 34 along the sliding direction of the base 21. The locking bolt 351 slides through the bar hole 341 and is threadedly connected to the base 21. The head of the locking bolt 351 is tightly pressed against the connecting rod 34, and the locking bolt 351 can slide in the bar hole 341 along the length direction of the bar hole 341.

[0038] The staff first turns the locking bolt 351 so that the locking bolt 351 is away from the connecting rod 34, releasing the contact between the head of the locking bolt 351 and the connecting rod 34, and then drives the base 21 to slide on the support 1, adjusts the position of the base 21, and then adjusts the position of the cutter 22 along the width direction of the film, so that the cutter 22 can cut edges of different widths of the film. Then the staff turns the locking bolt 351 again so that the locking bolt 351 is close to the connecting rod 34, and the head of the locking bolt 351 is pressed against the connecting rod 34, and then presses the connecting rod 34 against the base 21, which can lock the connecting rod 34 on the base 21, adjust the connection position of the connecting rod 34 and the base 21, and then adjust the position of the subsequent connecting rod 34 to drive the base 21 to move.

[0039] The implementation principle of a film edge cutting device in an embodiment of the present application is as follows: when the winding device is winding the film, the driving motor 31 is started, and the output shaft of the driving motor 31 drives the cam 32 to perform eccentric reciprocating rotation in a circumferential direction, and the cam 32 drives the driving rod 33 to move back and forth, and the driving rod 33 drives the connecting rod 34 to move back and forth in the width direction of the film, and the connecting rod 34 drives the two bases 21 to move back and forth in the width direction of the film. The two bases 21 can drive the two cutters 22 to move back and forth in the width direction of the film, thereby conveniently and quickly driving the two cutters 22 to move back and forth at the same time. The two cutters 22 cut the two edges of the film unevenly, so that more air can enter between the films, improving the problem of easy adhesion between the films, and when the winding roller subsequently winds the film, it is easier to expel the air as the winding roller squeezes, so that the film can be wound flatly, improving the problem of air remaining between the two films and causing adhesion and bulging, and effectively improving the winding effect of the film.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
