Description

Technical Field

[0001] This utility model relates to the field of membrane cutting technology, specifically to a membrane cutting device with stable cutting capabilities. Background Technology

[0002] As a functional material, membranes are widely used in modern industry, technology and daily life. Membrane cutting is a common process in industries such as electronics manufacturing, automobiles, construction and packaging. Its core is to precisely divide thin film materials into the required size and shape through physical or laser means.

[0003] Chinese Patent Publication No. CN222521488U, authorized on February 25, 2025, discloses a packaging film cutting device, belonging to the field of packaging cutting technology. This device includes a cutting platform, on which a feeding roller assembly, a transmission roller assembly, and a cutting bracket are mounted. An electric telescopic rod is mounted on the cutting bracket, and its output end is connected to a cutting blade assembly. The cutting blade assembly includes a blade holder, with a movable groove at the bottom of the blade holder adapted to the cutting blade head, a sliding groove at the top of the movable groove, and a slider adapted to the sliding groove at the top of the cutting blade head. A through hole is formed in the middle of the cutting blade head, and a movable shaft is located in the middle of the movable groove. The movable shaft passes through the through hole and is used to movably connect the cutting blade head inside the blade holder. A return spring is sleeved on the outside of the movable shaft at one right end of the movable groove. This invention solves the problem that effective cutting cannot be achieved by simply pressing down to cut.

[0004] Current membrane cutting methods typically involve applying pressure by pressing down on the membrane with a cutting blade. However, when cutting membranes with high toughness, the blade cannot cut instantly upon contact with the membrane, causing it to stretch and become loose. This can result in uneven cut surfaces, reduced cutting efficiency, and failure to meet usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide a stable film cutting device to solve the problem mentioned in the background art that existing film cutting generally completes the cutting by pressing down the cutting blade to contact the film and applying pressure. When cutting high-toughness films, the cutting blade cannot cut instantly when it contacts the film, which will pull the film and cause the film to be in a relaxed state. This easily leads to uneven cutting end face, reduces the film cutting effect, and fails to meet the usage requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a film cutting device with stable cutting capability, comprising a cutting table, a cutting groove provided at the center of the upper end of the cutting table, a mounting frame provided above one side of the cutting table and fixedly connected to the cutting table, the mounting frame being L-shaped, a mounting plate provided on the inner side of the mounting frame and positioned above the cutting groove, a first electric push rod provided above the mounting plate and connected to the mounting frame by screws, the telescopic end of the first electric push rod being connected to the mounting plate, a cutting blade provided below the mounting plate and correspondingly positioned to the cutting groove, a rubber block provided below each side of the cutting blade, a compression spring provided above the rubber block and fixedly connected to the mounting plate and the rubber block at both ends.

The upper end of the cutting blade is provided with a threaded hole. A connecting bolt is provided above the mounting plate, and the connecting bolt is correspondingly provided with the threaded hole. The connecting bolt is slidably connected to the mounting plate and is threadedly connected to the cutting blade.

[0009] Preferably, the inner wall of the mounting bracket is provided with a first sliding groove, the inside of the first sliding groove is provided with a first slider, and the first slider is slidably connected to the mounting bracket. The first slider is located on one side of the mounting plate and is fixedly connected to the mounting plate.

[0010] Preferably, the cutting groove is provided with two sponge bodies, which are fixedly connected to the cutting table, and the two sponge bodies are symmetrically arranged inside the cutting groove.

[0011] Preferably, the cutting table is provided with four support legs below it, and the support legs are connected to the cutting table by screws. A support roller is provided above each end of the cutting table, and the support roller is rotatably connected to the cutting table.

[0012] Preferably, two columns are provided above the cutting table, and the columns are fixedly connected to the cutting table.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model device is equipped with a mounting plate, a cutting blade, a first electric push rod, rubber blocks, and a compression spring. The cutting blade is connected to the mounting plate by screws, which facilitates the replacement of the cutting blade. The first electric push rod drives the mounting plate to descend, and as the mounting plate descends, the cutting blade falls down. The falling cutting blade drives the rubber block to fall simultaneously. The falling rubber block first contacts the film, and the compression spring squeezes and applies a pushing force to the rubber block. With the help of the two rubber blocks, the film is pressed from both sides of the film cutting area. The falling cutting blade contacts the film and applies pressure, so the cut film will not be stretched. The cutting blade, together with the cutting groove, realizes the film cutting, and the cut end face is flat.

[0015] 2. The utility model device is equipped with a support roller, a column, a second electric push rod, a second slide groove, a second slider and a pressure roller. The support roller contacts the film and provides support for the film. The rotating support roller facilitates the film's transport on the cutting table. The second electric push rod drives the second slider to move up and down in the second slide groove, changing the height of the pressure roller. The pressure roller, in conjunction with the support roller, contacts the upper and lower ends of the film to press the film and ensure that the transported film is in a straight state.

[0016] 3. This utility model device, through the setting of the sponge body, allows the falling cutting blade to be inserted into the sponge body, which can not only completely cut the film, but also protect the cutting blade. Attached Figure Description
