Abstract
Description
Technical Field
[0001] This utility model belongs to the field of film cutting technology, and specifically relates to a film cutting device. Background Technology
[0002] Silver-coated photographic film, also known as roll film, is a photosensitive material primarily used for photography and is typically stored in a film cassette. A roll of film has a starter and a stopper. When storing the film in the cassette, the stopper is inserted into the cassette's spool, and the film wraps around the spool several times. The starter is located near the opening of the cassette. The starter is designed with an L-shaped end to fit the camera, while the stopper is designed with a pointed tip to correspond to the cassette's spool. In other words, the starter and stopper of the film have two different shapes.
[0003] The film roll's beginning and end are cut into their respective shapes using separate beginning and end cutting devices. However, existing beginning and end cutting devices are two different types of equipment, requiring separate operations, which makes the film cutting process cumbersome and inconvenient. Therefore, it is necessary to design a film roll beginning and end cutting device that integrates both. Utility Model Content

[0029] like Figures 2 to 4 As shown, preferably, the first support 12 and the second support 13 are spaced apart, such that the first blade 23 and the second blade 24 are spaced apart; the cutting edges of the first blade 23 and the second blade 24 face the working surface 11; the groove of the second blade 24 faces the vertical end of the first blade 23; the working surface 11 is provided with a first groove 14 and a second groove 15 corresponding to the first blade 23 and the second blade 24, the shape of the first groove 14 is the same as the shape of the first blade 23, and the shape of the second groove 15 is the same as the shape of the second blade 24.

Additionally, it should be noted that the specific model of the motor involved is not the improvement point of this application, and the connection method between the motor and the controller is a conventional connection, which will not be described in detail here.
[0032] Work style:
[0033] In use, the film head is inserted into the slide 16, and the protrusions on the conveyor roller 33 are inserted into the slots on both sides of the film. Then, the controller 31 starts the motor 32 to rotate, which drives the conveyor roller 33 to rotate. The protrusions rotate with the conveyor roller 33 and alternately insert into the slots on both sides of the film, moving the film along the slide 16. When the film head moves directly below the first blade 23, the motor 32 stops rotating, and the first linear movement mechanism 21 is started. The movable end of the first linear movement mechanism 21 drives the first blade 23 to move towards the film head, and the first blade 23 cuts the film head. The film is inserted into the first slot 14, and then the motor 32 is started. The motor 32 continues to move the film. When the end of the film is directly below the second blade 24, the motor 32 is stopped, and the second linear movement mechanism 22 is started. The movable end of the second linear movement mechanism 22 moves the second blade 24 toward the end of the film. The second blade 24 cuts the end of the film and inserts into the second slot 15. Then the motor 32 is started again, and the film is moved again. The cutting of the beginning and end of the film is completed in one go, without the need to cut the film separately, simplifying the film cutting process and effectively shortening the film cutting process.
[0034] like Figure 3 and Figure 4As shown, preferably, the control component 3 further includes a first photoelectric sensor 34; the working surface 11 has a first light-transmitting hole corresponding to the first blade 23, the first light-transmitting hole is close to the first slot 14 and aligned with the end of the first slot 14 away from the second slot 15; the first photoelectric sensor 34 is disposed on the first light-transmitting hole, with its detection end facing upward, to detect whether there is film; the first photoelectric sensor 34 is circuitally connected to the controller 31; when the beginning of the film passes through the first light-transmitting hole, the film covers the first photoelectric sensor 34, the first photoelectric sensor 34 sends a signal to the controller 31, the controller 31 controls the motor 32 to stop running, and then the controller 31 controls the first linear movement mechanism 21 to start, the first linear movement mechanism 21 drives the first blade 23 to cut the beginning of the film, after the cutting is completed, the controller 31 restarts the motor 32 to move, driving the film to continue moving forward, thereafter even if the first photoelectric sensor 34 detects film, the controller 31 does not control the first linear movement mechanism 21 and the motor 32 to stop running, until the second linear movement mechanism 22 drives the second blade 24 to cut the end of the film. Additionally, it should be noted that the specific model of the first photoelectric sensor is not an improvement of this application, and the connection method between the first photoelectric sensor and the controller is a conventional connection, which will not be elaborated here.

When the second photoelectric sensor 35 is simultaneously covered, the controller 31 stops the motor 32 and then starts the first linear motion mechanism 21 to cut the film head. After the film head is cut, the first linear motion mechanism 21 resets and continues to operate until the second linear motion mechanism 22 stops cutting with the second blade 24. The motor 32 and the conveyor roller 33 continue to move the film forward. When the film no longer covers the second photoelectric sensor 35 but covers the first photoelectric sensor 34, the film tail has moved below the second blade 24. At this time, the controller 31 starts the second linear motion mechanism 22, and the second blade 24 cuts the film, completing the cutting of the film tail, thus achieving automatic cutting of the film head and tail. It should also be noted that the specific model of the second photoelectric sensor is not an improvement of this application. The connection between the second photoelectric sensor and the controller is a conventional connection and will not be described further here.
[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
