Description

Technical Field

[0001] The utility model relates to the technical field of dimming film production, in particular to a dimming film cutting device. Background Art

[0002] Smart film is an electronic light-control product with switchable states. It is usually used in bathrooms, offices and other areas that require specific privacy. However, in the actual production process of most smart films, the specifications of the smart films produced by different assembly lines are different, and operators are required to cut the smart films. The existing cutting process is mostly manual cutting with a cutting knife, which cannot guarantee the regularity of the cutting of the smart film. At the same time, the efficiency of manual cutting is relatively low.

[0003] For example, Chinese patent announcement No. CN218576350U discloses a cutting device for a dimming film. When in use, the dimming film is first pressed and fixed by a pressing mechanism, and then the lifting cylinder drives the right-angle mounting plate to move downward, so that the lower end of the cutting knife extends into the cutting groove, and at the same time, the cutting motor drives the driving gear to rotate, and the driving gear drives the transmission gear to rotate, and the transmission gear drives the cutting knife to rotate, and then the driving motor drives the second screw rod to rotate, and the second screw rod drives the driving block to move along the direction of the sliding guide rail, and the driving block drives the cutting knife at the lower end to move at the same time, and the dimming film is cut through the cutting knife, and the pressing cylinder drives the pressing plate to move downward, so that the pressing rubber pad is pressed on the upper end of the dimming film, thereby relatively fixing the dimming film to prevent the dimming film from moving during the cutting process, resulting in the dimming film cutting position not being neat, and the pressing position of the pressing rubber pad is at one side edge of the cutting groove.

[0004] However, the cutting device of the dimming film in the above application still requires manual labor to pull the dimming film, which is inefficient and may cause wrinkles on the dimming film during the pulling process. Therefore, there are certain limitations.

[0005] Therefore, we urgently need to provide a dimming film cutting device. Utility Model Content

[0006] The purpose of the utility model is to provide a dimming film cutting device to solve the problem that the dimming film cutting device proposed in the above background technology still requires manpower to pull the dimming film, which is relatively inefficient and may cause wrinkles on the dimming film during the pulling process.

[0007] To achieve the above objectives, the utility model provides the following technical solutions: a dimming film cutting device, comprising a cutting table and supporting legs, wherein the four supporting legs are respectively fixedly connected to the four corners of the lower surface of the cutting table, and the upper surface of the cutting table is provided with a loading device and a cutting device.

[0008] The feeding device comprises a feeding unit and a smoothing unit.

[0009] The feeding unit comprises an electric guide rail, a guide rail seat, and a clamping assembly. The electric guide rail is installed at the front end of the upper surface of the cutting table, the guide rail seat is slidably connected to the electric guide rail, and the clamping assembly is installed on the inner side of the guide rail seat.

[0010] A further improvement is that the clamping assembly includes a base, a sliding sleeve, an electromagnet, an elastic rope, a sliding rod, and a pressure plate, the base is fixedly connected to the inner bottom of the guide rail seat, the sliding sleeve is installed on the inner side of the guide rail seat, the electromagnet is installed on the top wall of the sliding sleeve, the elastic rope is fixedly connected to the bottom center of the electromagnet, the sliding rod is fixedly connected to the bottom of the elastic rope, and the pressure plate is fixedly connected to the bottom of the sliding rod.

[0011] A further improvement is that the slide bar is made of magnetic material, and there are two groups of feeding units. The two groups of feeding units are symmetrically installed on the front and rear sides of the upper surface of the cutting table, and the two ends of the dimming film are placed on the base respectively. Then the electromagnet is energized to generate a repulsive force between the slide bar, pushing the slide bar to slide downward along the sliding sleeve, and then pushing the pressure plate to move downward to clamp the dimming film between the base and the pressure plate, and then driving the guide rail seat to move to the left along the electric guide rail, thereby realizing automatic pulling and feeding, and avoiding wrinkles in the dimming film caused by uneven manual pulling force.

[0012] A further improvement is that the smoothing unit includes a U-shaped frame, an electric lifting rod, a U-shaped seat, and a smoothing assembly, the U-shaped frame is installed at the top right end of the two electric guide rails, the electric lifting rod is installed at the top center of the U-shaped frame, the U-shaped seat is fixedly connected to the bottom of the electric lifting rod, and the smoothing assembly is installed inside the U-shaped seat.

[0013] A further improvement is that the smoothing assembly includes a rotating bearing, a rotating shaft, and a smoothing roller. The two rotating bearings are respectively installed at the front and rear ends of the U-shaped seat. The rotating shaft is rotatably connected to the inside of the rotating bearing, and the smoothing roller is fixedly connected to the outside of the rotating shaft. The electric lifting rod is started to drive the U-shaped seat to move downward, so that the smoothing roller moves down to contact the surface of the dimming film. While pulling the dimming film, the friction between it and the smoothing roller causes the rotating shaft inside the rotating bearing to rotate, thereby driving the smoothing roller to rotate and smooth the dimming film while pulling the feeding material to avoid wrinkles.

[0014] A further improvement is that the cutting device includes a second guide rail seat, an electric slide rail frame, a slide rail seat, and a laser cutter, the two second guide rail seats are respectively slidably connected to the electric guide rails, the electric slide rail frame is installed on the top of the second guide rail seat, the slide rail seat is slidably connected to the electric slide rail frame, and the laser cutter is installed on the left bottom of the slide rail seat.

[0015] A further improvement is that a controller is installed on the right side of the front of the cutting table, the loading device and the cutting device are electrically connected to the controller respectively, and a length gauge is plated and engraved on the middle of the upper surface of the cutting table. According to the actual required length of the dimming film, the second guide rail seat is driven to move left on the electric guide rail, and the length is determined in conjunction with the length gauge, and then the laser cutter is started, and then the slide rail seat is driven to move back and forth along the electric slide rail frame to cut the dimming film.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The dimming film cutting device places the two ends of the dimming film on the base respectively, and then energizes the electromagnet to generate repulsive force between the slide bar, pushing the slide bar to slide downward along the sliding sleeve, and then pushing the pressure plate to move downward to clamp the dimming film between the base and the pressure plate, and then drives the guide rail seat to move to the left along the electric guide rail, so as to realize automatic pulling and feeding, avoiding uneven manual pulling force that causes wrinkles in the dimming film.

[0018] 2. The dimming film cutting device starts the electric lifting rod to drive the U-shaped seat to move downward, so that the smoothing roller moves down to contact the surface of the dimming film. While pulling the dimming film, the friction between it and the smoothing roller causes the internal rotating shaft to rotate inside the rotating bearing, thereby driving the smoothing roller to rotate and smooth the dimming film while pulling the feeding material to avoid wrinkles. It can also adapt to dimming films of different thicknesses, thereby improving the application range of the device.

[0019] 3. The dimming film cutting device drives the second guide rail seat to move left on the electric guide rail, cooperates with the length gauge to determine the length, then starts the laser cutter, and then drives the slide rail seat to move forward and backward along the electric slide rail frame to cut the dimming film.
