[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example 1 Reference Figures 1-5This is the first embodiment of the present invention. This embodiment provides a positioning fixture for producing toner cartridge films, including a fixture component, including a cutting table 10 and a cutting assembly 11 mounted on the cutting table 10. A fixture assembly 12 located on the side of the cutting assembly 11 for conveying toner cartridge films is mounted on the cutting table 10. A power assembly 13 for driving the fixture assembly 12 is mounted at the tail end of the cutting table 10. An adjustment assembly 14 for positioning the film during cutting is mounted on the cutting table 10 between the fixture assembly 12 and the cutting assembly 11. A drive assembly 15 for driving the adjustment assembly 14 is mounted on the side end of the cutting table 10. A conversion component includes a first conversion assembly 20 mounted on one end of the cutting table 10, and the first conversion assembly 20 is rotatably connected to one end of the adjustment assembly 14. A second conversion assembly 21 rotatably connected to the adjustment assembly 14 is mounted on the end of the cutting table 10 away from the first conversion assembly 20. The adjustment of the first conversion assembly 20 and the second conversion assembly 21 can adjust the distance between the adjustment assembly 14 and the film.

[0019] The cutting assembly 11 includes a lower cutting blade 111 and an upper cutting blade 112 that are symmetrically mounted on the cutting table 10.

[0020] The clamping assembly 12 includes multiple conveying shafts 123 rotatably connected to the inner wall of the cutting table 10. A pair of clamping plates 124 are symmetrically fitted on the surface of the multiple conveying shafts 123. An upper roller 121 and a lower roller 122 are rotated up and down in sequence near the lower cutting blade 111 on the inner wall of the cutting table 10.

[0021] Preferably, the power assembly 13 includes a servo motor 131 fixedly connected to the side of the cutting table 10. A pair of support frames 135 are symmetrically fixedly connected inside the cutting table 10. A lead screw 132 is rotatably connected between the inner wall of the cutting table 10 and the two support frames 135. The two lead screws 132 are arranged vertically and staggered. A connecting shaft 133 is fixedly connected to one end of each lead screw 132. Gears 134 are sleeved on the surface of each connecting shaft 133, and the two gears 134 are meshed together. The adjustment component 14 includes two linear guide rails 141 symmetrically rotatably connected to the inner wall of the cutting table 10. A slider 142 is slidably connected between the two linear guide rails 141, and an upper roller 121 is rotatably connected between the two sliders 142. A connecting block 143 is symmetrically fixedly connected to one end of the two sliders 142 near the lower cutting blade 111. A pressure plate 144 is rotatably connected between the two connecting blocks 143.

[0022] Furthermore, the pressure plate 144 remains horizontal to the bottom wall of the upper roller 121.

[0023] It should be noted that the drive assembly 15 includes a support plate 151 fixed to the side of the cutting table 10. A turntable 152 is rotatably connected to the support plate 151 via a coupling. The side of the turntable 152 near the cutting table 10 is connected to one of the sliders 142 via a pull rope 155. The lead screw 132 near the turntable 152 and the surface of the coupling are both fitted with belt pulleys 154, and the two belt pulleys 154 are connected by a belt 153.

[0024] During use, the toner cartridge film is conveyed via conveyor shaft 123 to the area between the lower cutting blade 111 and the upper cutting blade 112 for cutting. First, a servo motor 131 drives the lead screw 132, which is connected by two meshing gears 134. This causes the two lead screws 132 to rotate synchronously in opposite directions, moving the surfaces of the two clamping plates 124 closer together or further apart to adjust the spacing. This adjustment is based on the width of the film to be cut, ensuring contact with both sides of the film and maintaining its position during conveying to prevent misalignment from affecting the accuracy of subsequent cutting. Simultaneously, before film cutting, the servo motor 131 drives the lead screw 132, which, through two belt pulleys 154 and... The belt 153 drives the connected turntable 152 to rotate synchronously. As the turntable 152 rotates, it drives the slider 142 on the linear guide rail 141 to reciprocate through the pull rope 155. This causes the upper roller 121 and the pressure plate 144 to move with the slider 142. When the slider 142 moves downward, the upper roller 121 and the pressure plate 144 move downward to press against the film, thereby positioning it and preventing it from being loose during cutting, which would cause cutting deviation. After cutting, the upper roller 121 and the pressure plate 144 move upward with the linear guide rail 141 to reset, so that there is a gap between the upper roller 121 and the lower roller 122 for the film to continue to be transported.

[0025] Example 2 Reference Figures 1-3 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides... Specifically, the first conversion component 20 includes a bayonet 201 opened at one end of the cutting table 10 near the turntable 152, and a linear guide rail 141 is embedded in the bayonet 201. A first threaded shaft 202 is rotatably connected to the inner top wall of the bayonet 201, and the linear guide rail 141 is sleeved on the surface of the first threaded shaft 202 through the bayonet 201. Nuts 204 located on both sides of the bayonet 201 are threadedly connected to the surface of the first threaded shaft 202, and a sleeve rod 203 located between the linear guide rail 141 and the nuts 204 is sleeved on the surface of the first threaded shaft 202.

[0026] The second conversion assembly 21 includes a second threaded shaft 211 rotatably connected to the cutting table 10 at the end away from the first conversion assembly 20 and corresponding to the first threaded shaft 202, and a linear guide rail 141 on the side away from the first conversion assembly 20 is fixedly connected to the second threaded shaft 211, and a limit ring 212 is threadedly connected to the surface of the second threaded shaft 211 on the side away from the linear guide rail 141.

[0027] When changing the film cutting length during use, the nut 204 and the limiting ring 212 can be loosened first, so that the two linear guides 141 can be rotated on the first threaded shaft 202 and the second threaded shaft 211 respectively to adjust the tilt angle, thereby changing the time when the pressure plate 144 and the upper roller 121 move down to press with the film, indirectly matching the film cutting time interval. After the angle of the linear guide 141 is adjusted, the nut 204 can be turned to position one of the linear guides 141, and then the limiting ring 212 can be turned to position the other linear guide 141 to complete the adjustment of the downward movement time of the upper roller 121 and the pressure plate 144.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
