[0029] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] The embodiment of the present utility model provides a film body deviation rectifying device for a film cutting machine, which is used on the film cutting machine to convey the mobile phone film towards the cutting device of the film cutting machine and rectify the mobile phone film during the conveying process, so as to solve the technical problem that the mobile phone film is prone to deviation during the conveying process to the cutting mechanism in the prior art, resulting in a reduction in the yield rate of the cut mobile phone film.

[0031] To achieve the above technical purpose, the technical solution of the present utility model provides a film body deviation rectifying device for a film cutting machine, as Figure 1-2 shown, including a base 10, a conveying frame 20, a sensor 30 and a driving member (not marked in the figure). The conveying frame 20 is rotatably connected to the base 10. Conveying rollers 21 are arranged on both sides of the conveying frame 20, and the conveying rollers 21 are used to convey the mobile phone film. The sensor 30 is installed on the base 10 and is located on one side of one of the conveying rollers 21, and is used to sense the distance between the mobile phone films. The driving member is installed on the base 10 and is connected to the conveying frame 20, and is used to drive the conveying frame 20 to rotate through the distance sensed by the sensor 30 so as to rectify the mobile phone film.

[0032] Specifically, the deviation rectifying device is fixed to the film cutting machine through the base 10. The conveying frame 20 is rotatably connected to the base 10. Conveying rollers 21 are arranged on both sides of the conveying frame 20. The conveying rollers 21 can convey the mobile phone film in the direction of the cutting device by rotation. Through the simultaneous conveyance of the conveying rollers 21 on both sides, the stability of the mobile phone film during conveyance can be ensured. The sensor 30 is installed on the base 10 and is located on one side of one of the conveying rollers 21. When the mobile phone film is conveyed, it will pass through the sensor 30. The sensor 30 judges whether the mobile phone film is deviated by sensing the distance from the mobile phone film. The driving member is installed on the base 10 and is connected to the conveying frame 20. When the sensor 30 senses that the mobile phone film is deviated, it drives the conveying frame 20 to rotate at a small angle, adjusts the distance between the mobile phone film and the sensor 30 to the set range, and then rectifies the mobile phone film, so that the mobile phone film is conveyed to the cutting device at a proper angle, thereby improving the cutting accuracy of the mobile phone film.

[0033] In this embodiment, the deviation rectifying device mainly conveys and rectifies the mobile phone film. It can be understood that it can also be used for conveying other types of film bodies similar to the mobile phone film. When used for conveying other types of film bodies, the conveying and rectifying principles are the same as those for the mobile phone film conveying and rectifying.

[0034] In this embodiment, as Figure 1 shown, the base 10 is provided with a straight groove 11. The base 10 can be fixed to the frame of the film cutting machine by bolts passing through the straight groove 11, and the fixed position can be finely adjusted through the straight groove 11.

[0035] In this embodiment, as Figure 1-2 shown, the conveying frame 20 is a table structure. After the mobile phone film is fed from the feeding frame, it is upwardly pulled to one of the conveying rollers 21, then passes through the table surface of the conveying frame 20 and enters the other conveying roller 21, and then is downwardly pulled from this conveying roller 21 to the sensor 30. During the conveyance of the mobile phone film, the conveying rollers 21 on both sides will be driven to rotate.

[0036] Optionally, as Figure 1-2 shown, the two sides of the conveying frame 20 are provided with rotation chambers 22, and the conveying rollers 21 are arranged in the rotation chambers 22. Specifically, on the one hand, the rotation chambers 22 can protect the conveying rollers 21, and on the other hand, they can limit the mobile phone film to ensure the stability of the mobile phone film during conveyance.

[0037] Optionally, as Figure 2As shown in the figure, a film retaining frame 221 is provided on the top wall of the film supply cavity 22. A film passing gap 222 for the mobile phone film to pass through is formed between the film retaining frame and the conveying roller 21. Specifically, the mobile phone film can pass into or out of the conveying roller 21 through the film passing gap 222, and the film retaining frame 221 can limit the mobile phone film passing into or out of the conveying roller 21, avoiding the warping of the mobile phone film during conveying and ensuring the stability of the mobile phone film during conveying.

[0038] Optionally, as Figure 2 shown, the base 10 is provided with a sliding frame 12, and a sliding frame 23 is provided on the side of the conveying frame 20 close to the base 10. The sliding frame 23 is slidably connected to the sliding frame 12 and can slide along the sliding frame 12 through the rotation of the conveying frame 20. Specifically, the sliding frame 12 is located on the rotation path of the sliding frame 23. By sliding the sliding frame 23 along the sliding frame 12, the connection between the conveying frame 20 and the base 10 can be strengthened, avoiding the yaw of the conveying frame 20, so that the conveying frame 20 can always maintain a horizontal state, thereby ensuring the stable conveying of the mobile phone film.

[0039] In this embodiment, as Figure 2 shown, the number of the sliding frame 12 and the sliding frame 23 is two each to ensure the stability of the conveying frame 20.

[0040] It can be understood that the sliding frame 23 can be slidably connected to the sliding frame 12 through forms such as sleeving on the sliding frame 12.

[0041] Optionally, as Figure 2 shown, the sliding frame 12 is provided with a sliding groove 121, and the sliding frame 23 is provided with a sliding member 231. The sliding member 231 is slidably connected to the sliding groove 121 and can slide along the sliding groove 121 through the rotation of the conveying frame 20. Specifically, through the cooperation of the sliding member 231 and the sliding groove 121, while realizing the sliding connection between the sliding frame 12 and the sliding frame 23, it is convenient for the disassembly and assembly of the conveying frame 20.

[0042] In this embodiment, as Figure 2 shown, the sliding groove 121 is provided on the side of the sliding frame 12.

[0043] Optionally, as Figure 2 shown, the sliding member 231 is provided with a roller 232. The roller 232 can roll along the sliding groove 121 through the rotation of the conveying frame 20. Specifically, the roller 232 can reduce the friction between the sliding member 231 and the sliding groove 121 and facilitate the driving of the conveying frame 20.

[0044] Optionally, as Figure 2As shown, the base 10 is further provided with a support frame 13. One side of the conveying frame 20 close to the base 10 is further provided with a connecting frame 24, and the connecting frame 24 is hinged to the support frame 13. Specifically, through the hinge connection between the connecting frame 24 and the support frame 13, the conveying frame 20 can be further supported, thereby further improving the stability of the conveying frame 20 and the conveying accuracy of the mobile phone film.

[0045] Optionally, as Figure 2 shown, the support frame 13 is provided with a universal ball head 131, and the support frame 13 is hinged to the connecting frame 24 through the universal ball head 131. Specifically, the hinge form in which the support frame 13 is hinged to the connecting frame 24 through the universal ball head 131 enables the conveying table to rotate relative to the support frame 13 at any angle, improving the flexibility of the conveying frame 20 and preventing the support frame 13 from interfering with the rotation of the conveying frame 20.

[0046] It can be understood that the sensor 30 can be connected to the base 10 through connection forms such as fixed connection and sliding connection.

[0047] Optionally, as Figure 1-2 shown, the base 10 is further provided with an adjusting frame 14. The adjusting frame 14 is arranged in parallel with the conveying roller 21, and the sensor 30 is slidably connected to the adjusting frame 14. Specifically, by sliding along the adjusting frame 14, the sensor 30 can adapt to the induction of mobile phone films of different sizes, and further enable the conveying device to adapt to the deviation correction of mobile phone films of different sizes.

[0048] Optionally, the driving member includes a motor. As Figure 1-2 shown, the base 10 is provided with an installation cavity 15, and the motor is arranged in the installation cavity 15 and connected to the conveying frame 20. Specifically, the conveying frame 20 can be driven by the motor, and the installation cavity 15 can protect the motor.

[0049] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention shall be included in the protection scope of the claims of the present invention.
