Description

Technical Field

[0001] The utility model relates to the technical field of display film cutting, and more specifically to an LED photoelectric display film cutting device. Background Art

[0002] LED optoelectronic display film generally refers to the film material used in LED display technology. In the preparation process of LED display devices, the optoelectronic display film is cut to obtain display devices of required size and shape, so it is necessary to cut the LED optoelectronic display film. In the prior art, when cutting traditional films, only one end of the film is tightened, and the film needs to be manually unfolded for subsequent use.

[0003] In view of the above problems, regarding the technical problem of insufficient fixation during film cutting, after a lot of searching, a film cutting device with patent number CN219748089U was found, including a base, a side plate fixedly arranged on the base, a sleeve rod fixedly arranged on the side plate, a film roller sleeved on the sleeve rod, a fixed seat fixedly arranged on the base, a cutting table fixedly arranged on the fixed seat, a cutting opening corresponding to the film is opened on the cutting table, a film cutting mechanism and a film pressing mechanism are arranged in the cutting opening, a sliding seat is slidably arranged on the base, two connecting rods are symmetrically fixed on the sliding seat, and a film clamping mechanism is arranged on both connecting rods; the utility model can quickly tighten the film on the film roller, and cut after fixing the cutting position, effectively avoiding the problem of stacking and sticking the film after cutting, and facilitating the subsequent use of the cut film; however, the technical solution provided by the patent has the following problems:

[0004] (1) Each time a section of film is cut, the user needs to repeatedly press the film cutting position in advance through the pushing mechanism, and the film is not convenient for multiple equidistant cuts, making film cutting inconvenient;

[0005] (2) One end of the film is fixed by a film clamping mechanism, so that when the film moves before and after cutting, it needs to be locked and released repeatedly, which makes the film conveying inconsistent and leads to slow cutting efficiency.

[0006] The utility model can limit the film and perform equidistant cutting, making the film cutting process more convenient and faster. Utility Model Content

[0007] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provides an LED photoelectric display film cutting device.

[0015] A further preferred solution is that the electric telescopic rod is installed in the middle of the top of the cutting table by means of bolts, and the bottom end of the electric telescopic rod penetrates to the inner upper end of the cutting table and is fixedly connected to the lifting frame.

[0016] A further preferred solution: the lifting frame is in a U-shape, and the thickness of the lifting frame is 5-10 mm.

[0017] Beneficial effects:

[0018] 1. By setting a film adaptive positioning mechanism, when the LED photoelectric display film to be cut enters and passes through the guide frame, it can be limited and guided by two symmetrical guide rollers, and when the thickness of the LED photoelectric display film to be cut is larger, the two symmetrical guide rollers can be squeezed to open, so that the two guide rollers slide along the slide groove more stably and the compression spring is compressed; thereby, the thickness of the LED photoelectric display film to be cut can be adaptively adjusted, and the elastic potential energy of the compression spring can allow the two symmetrical guide rollers to continuously provide a clamping and guiding effect on the LED photoelectric display film to be cut; so that the transmission and movement of the LED photoelectric display film to be cut is more stable;

[0019] 2. By setting up a film-fixed-distance cutting mechanism, when the LED photoelectric display film to be cut passes through the positioning roller, the electric telescopic rod can push the lifting frame downward to make the positioning roller closely fit the LED photoelectric display film to be cut; then, as the positioning roller rotates, the contact surface between the positioning roller and the LED photoelectric display film to be cut will be squeezed and deformed; thereby, a negative pressure state is formed in the multiple circular grooves on the outer surface of the positioning roller; thereby, the contact with the LED photoelectric display film to be cut is more firm and stable; at the same time, as the positioning roller rotates one circle, the LED photoelectric display film to be cut can be evenly divided by the cone blade; so that the LED photoelectric display film to be cut can be evenly cut while being transported and moved, thereby improving the efficiency and convenience of cutting;

[0020] 3. In summary, the LED photoelectric display film cutting equipment is provided with an adaptive positioning mechanism which takes into account the stability and clamping requirements of films of different thicknesses during the cutting process. Through the combination of guide rollers, slide grooves and compression springs, it can effectively achieve stable guidance and clamping of the film to be cut, making the cutting process more precise and stable. The film fixed-distance cutting mechanism is provided to ensure that the film is accurately cut into equidistant parts under the drive of the positioning rollers, thereby achieving the purpose of fixed-distance cutting.
