Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1

[0023] As Figures 1 - 5 shown, the present invention provides a technical solution: a stretch film cutting device with adjustable spacing, including a cutting component 1, an installation component 4 is arranged inside the cutting component 1, an adjusting component 2 is arranged outside the cutting component 1, and flattening components 3 are arranged at both ends of the cutting component 1. The cutting component 1 includes a mounting groove 103 and a cutting scissors 104. The cutting scissors 104 are arranged inside the mounting groove 103. Cylinders 102 are symmetrically installed at the top of the mounting groove 103. The installation component 4 includes a limit rod 402. One end of the limit rod 402 penetrates through the inside of the mounting groove 103 and the cutting scissors 104. A link rod 401 is installed at one end of the limit rod 402. A fixed rod 403 penetrates through the inside of one end of the limit rod 402. A pin plate 404 is installed at the bottom of the fixed rod 403. A plurality of fastening strips 405 are distributed on the outside of the pin plate 404. Fixed frames 406 are symmetrically installed on the side surface of the mounting groove 103. A limit strip 407 is installed inside the fixed frame 406. The limit strip 407 is clamped with the fastening strip 405.

[0024] In this embodiment, by pulling out the fixing rod 403 upward with force, the fastening strip 405 is separated from the limiting strip 407, so that the fixing rod 403 is disengaged from the inside of the limiting rod 402. Then, the limiting rod 402 is moved out to the side, so that the limiting rod 402 is disengaged from the inside of the mounting groove 103 and the cutting scissors 104, facilitating the removal of the cutting scissors 104 for maintenance and replacement. The operation is convenient and fast, without the need to use professional tools, reducing the labor cost and time cost. This is conducive to improving the maintenance efficiency, reducing the downtime of the equipment, facilitating the replacement of different cutting scissors 104 according to requirements, thus improving the overall working efficiency. By the engagement of the fastening strip 405 and the limiting strip 407, it is beneficial to ensure the stability of the installation of the fixing rod 403. The fixing rod 403 is beneficial to limit the limiting rod 402. By the extension of the cylinder 102 to push the mounting groove 103 downward, the cutting scissors 104 can cut the stretch film.

[0025] Embodiment 2

[0026] As Figures 1 - 5 shown, the flattening assembly 3 includes two flattening rollers 303. A plurality of rubber strips 304 are distributed on the outer side of the flattening rollers 303. A rotating shaft 302 penetrates through the inside of the flattening rollers 303. Both ends of the rotating shaft 302 are connected with U-shaped frames 307. One end of the U-shaped frame 307 is provided with a rotating motor 301. An electric telescopic column 305 is installed on the top of the U-shaped frame 307. A side plate 306 is installed on the top of the electric telescopic column 305. One end of the side plate 306 is provided with a mounting frame 101. The adjusting assembly 2 includes a translation motor 201. One end of the translation motor 201 is provided with a threaded rod 202. A processing table 203 is installed on the outer side of the threaded rod 202. Support legs 204 are installed at the bottom of the processing table 203.

[0027] In this embodiment, by the electric drive of the translation motor 201 to rotate the threaded rod 202, it is beneficial to drive the mounting frame 101 to move on the processing table 203, facilitating the adjustment of the position of the cutting scissors 104 and thus facilitating the adjustment of the cutting spacing of the stretch film. When the cutting scissors 104 move to the position where cutting is required, by the downward movement of the electric telescopic column 305, the U-shaped frame 307 is driven to descend, so that the rubber strips 304 contact the stretch film. The rubber strips 304 are beneficial to increasing the friction between the flattening rollers 303 and the stretch film, ensuring the stability of the contact between the flattening rollers 303 and the stretch film. Then, by the electric drive of the rotating motor 301 to rotate the rotating shaft 302, the two flattening rollers 303 rotate in opposite directions, which is beneficial to flatten the stretch film, so that the stretch film remains flat during cutting, avoiding deviation of the cutting size due to uneven situations such as wrinkles and curls of the film, improving the cutting accuracy, and thus being beneficial to improving the cutting quality.

[0028] Working principle of this embodiment: When in use, first place the stretch film on the processing table 203. The translation motor 201 electrically drives the threaded rod 202 to rotate, which is beneficial to drive the mounting frame 101 to move on the processing table 203, facilitating the adjustment of the position of the cutting knife 104, and then facilitating the adjustment of the cutting spacing of the stretch film. When the cutting knife 104 moves to the position where cutting is required, the electric telescopic column 305 descends, driving the U-shaped frame 307 to descend, so that the rubber strip 304 contacts the stretch film. Then, the rotation motor 301 electrically drives the rotating shaft 302 to rotate, causing the two flattening rollers 303 to rotate in opposite directions, which is beneficial to flatten the stretch film and keep the stretch film flat during cutting. Subsequently, the cylinder 102 extends to push the mounting groove 103 downward, causing the cutting knife 104 to cut the stretch film. When maintenance of the cutting knife 104 is required, pull out the fixing rod 403 upward with force, so that the fastening strip 405 is separated from the limiting strip 407, and then the fixing rod 403 is disengaged from the inside of the limiting rod 402. Then, move the limiting rod 402 to the side, so that the limiting rod 402 is disengaged from the inside of the mounting groove 103 and the cutting knife 104, facilitating the removal of the cutting knife 104 for maintenance and replacement.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical solution content of the present invention is not departed from, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
