Abstract
Description
Technical Field
[0001] This utility model relates to the field of thin film processing technology, and more specifically, to a thin film slitting mechanism. Background Technology
[0002] Plastic film is a thin, soft, and transparent sheet. In the existing technology, the film is cut into strips of the required width by a slitting mechanism. However, there is horizontal movement space between some structures in the existing device. When the film is squeezed, it is easy to shift, resulting in inaccurate positioning and uneven slitting width.
[0003] To address the aforementioned issues, patent document publication number CN222181333U discloses a film slitting mechanism, comprising a frame and an air shaft at its top. The top of the frame is provided with a slide groove that can slide vertically, and a cutting assembly is provided at the bottom of the slide groove. The cutting assembly includes multiple parallel blade holders, with blades engaged at the bottom of each blade holder. A vertically mounted rotating shaft is provided on the side wall of each blade holder, and a connecting rod is hinged to the outer side of the rotating shaft.
[0004] However, in actual use, it still has some drawbacks. For example, the above device uses a spring and a limiting plate to press the limiting plate downwards, so that the limiting plate presses the blade holder against the bottom of the groove. The friction between the limiting plate and the blade holder achieves stable limiting of the blade holder, thereby preventing inaccurate division caused by horizontal displacement of the blade holder. However, since the blade is exposed at the bottom of the groove, there is a risk of scratches for the operator when adjusting or maintaining it, resulting in a significant safety hazard to the device itself. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a film slitting mechanism to solve the problem that the exposed blades in the prior art can easily cause injury to operators when maintaining the equipment.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a film slitting mechanism, including a slide groove, the film slitting mechanism further including...
[0007] Mounting base, the mounting base is fixedly mounted on the top surface of the slide groove;
[0008] The fixing posts are arranged opposite each other on one side of the mounting base. The fixing posts are rotatably connected to the internal part of the fixing posts, and the surface of the fixing posts is provided with abutment grooves.
[0009] A flip plate is fixedly installed on the surface of a connecting shaft. A fixing groove is provided on one side of the flip plate in the width direction. A baffle plate is fixedly connected to the bottom of the flip plate, and a flexible pad is provided at the bottom of the baffle plate.
[0010] The device also includes an electric push rod, a connecting plate, a rack, and a gear. The electric push rod is fixedly installed on the top of the mounting base, and the top end of the electric push rod is fixedly connected to the top of the connecting plate. The rack is arranged opposite to each other on both sides of the connecting plate in the width direction. The gear is fixedly installed on one end of the connecting shaft opposite to the fixed column, and the outer edge of the gear meshes with the outer edge of the rack.
[0011] It also includes a fastening assembly, which is disposed at the top of the slide.
[0012] The fastening assembly includes a connecting frame, a motor, a screw, a movable seat, and a concave snap-fit plate. The connecting frame is fixedly installed on the top surface of the slide groove. The motor is located on one side of the top of the connecting frame, and the drive shaft of the motor is fixedly connected to one end of the screw. The movable seat is threaded onto the surface of the screw, and the side of the movable seat is slidably connected to the surface of the connecting frame. The concave snap-fit plate is fixedly installed on the top of the movable seat, and one side of the concave snap-fit plate along its length engages with the inside of the fixed groove, with the surface of the concave snap-fit plate contacting the inside of the abutment groove.
[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0014] In the above scheme, when the device is being maintained as a whole, the electric push rod retracts to move the connecting plate downward, causing the racks on both sides of the connecting plate to move downward synchronously and mesh with the gears during the downward movement. This meshing causes the horizontal flip plate to flip and become vertical, thereby merging the two shielding plates to cover the outside of the blade. By merging the shielding plates to completely cover the blade, the blade is prevented from being exposed at the bottom of the slide groove, thus avoiding the risk of scratches to maintenance personnel and improving the safety of the device itself.
[0015] When the two baffles are combined, the motor drives the screw to rotate, allowing the movable seat mounted on the screw surface to move horizontally. This causes the concave snap-fit plate to move synchronously, and one side of it engages with the fixing groove on the side of the flip plate to secure the flip plate and prevent the baffles from separating. In addition, when the flip plate is in a horizontal state, the concave snap-fit plate can move horizontally to the bottom of the flip plate to provide auxiliary support for it and the baffles, preventing the flip plate from rotating unexpectedly during slitting operations and affecting the normal use of the blades.
