Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of strip film cutting equipment, and particularly relates to a strip film cutting mechanism. Background Technique
[0002] It is made of plastic, adhesive, rubber or other materials. The scientific explanation of film is: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of a substrate. A strip-shaped protective film needs to be pasted on the soft strip for insulating glass doors and windows.
[0003] After the strip film is wound, it needs to be cut. When cutting without pausing the traction, it is easy to damage the strip film. Waiting for pausing affects the production continuity, resulting in a relatively low practicality of the conventional strip film cutting mechanism.
[0004] Therefore, we propose a strip film cutting mechanism to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problem of relatively low practicality of the conventional strip film cutting mechanism, and propose a strip film cutting mechanism.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A strip film cutting mechanism includes a frame. A guide seat is rotatably installed on the upper part of the frame. A cylinder is fixedly connected inside the guide seat. A cutting knife is slidably installed inside the guide seat. The piston of the cylinder is fixedly connected with the cutting knife. The guide seat penetrates through the frame, and a spring is fixedly connected between the frame and the guide seat. Pass the strip film through between the guide seat and the cutting knife, and then pass the strip film downward through between the frame and the guide seat, so that the strip film is pulled downward along the guide seat. When cutting is required, drive the cylinder to drive the cutting knife to cut downward, cut the strip film downward through the cutting knife, and then quickly release. At the moment of cutting, use the guide seat to overcome the spring to rotate, so that it matches the cutting and traction speed, avoiding tearing and damaging the strip film, and improving the flatness of the cutting part.
[0008] Preferably, a spiral elastic tube is also fixedly connected inside the guide seat, and the spiral elastic tube is connected with the cylinder. It is convenient for the cylinder to be connected with an external air pump through the spiral elastic tube.
[0009] Preferably, a rotating cylinder is rotatably installed at the lower part of the frame. The rotating cylinder is used to reduce the moving resistance of the strip film.
[0010] Preferably, the frame includes a bearing seat, a fixed shaft, and a fixed block. The fixed block is fixedly connected to the lower part of the bearing seat, and one end of the fixed shaft is fixedly connected to the fixed block. The bearing seat facilitates guiding the rotation of the guide seat, and the fixed shaft facilitates guiding the rotation of the rotating cylinder.
[0011] Preferably, the guide seat includes a smooth seat body and a rotating shaft. A knife groove is formed at the upper end of the smooth seat body, and the rotating shaft is fixedly connected to the side end of the smooth seat body. The bearing seat is used to guide the rotation of the rotating shaft, enabling the smooth seat body to guide the synchronous movement of the strip-shaped film, facilitating the cutting to be synchronized with the movement of the strip-shaped film.
[0012] Preferably, the guide seat further includes a stop block, which is fixedly connected to one end of the rotating shaft facing away from the smooth seat body. The elastic force of the spring acts on the stop block, then through the stop block on the rotating shaft, and through the rotating shaft on the smooth seat body, so that after cutting, it is convenient for the smooth seat body to rotate and reset.
[0013] Preferably, the cutting knife includes a blade, a lifting column, and a connecting rod. The lifting columns are symmetrically and fixedly connected to the side ends of the blade, and the connecting rod is fixedly connected to the lower part of the lifting column. When the air cylinder extends, it acts downward on the connecting rod through the air cylinder, causing the connecting rod to act downward on the lifting column, and the lifting column to act downward on the blade, facilitating the blade to cut the strip-shaped film downward.
[0014] In summary, the technical effects and advantages of the present utility model are as follows:
[0015] 1. Pass the strip-shaped film through between the guide seat and the cutting knife, and then pass the strip-shaped film downward through between the frame and the guide seat, so that the strip-shaped film is pulled downward along the guide seat. When it needs to be cut, drive the air cylinder to drive the cutting knife to cut downward, cut the strip-shaped film downward through the cutting knife, and then quickly release. At the moment of cutting, use the guide seat to overcome the spring to rotate, making it match the cutting and traction speed, avoiding tearing and damaging the strip-shaped film, improving the flatness of the cutting part, and thus improving the practicability.
[0016] 2. Use the bearing seat to guide the rotation of the rotating shaft, enabling the smooth seat body to guide the synchronous movement of the strip-shaped film, facilitating the cutting to be synchronized with the movement of the strip-shaped film.
[0017] 3. Use the elastic force of the spring to act on the stop block, then through the stop block on the rotating shaft, and through the rotating shaft on the smooth seat body, so that after cutting, it is convenient for the smooth seat body to rotate and reset.
[0018] 4. When the air cylinder extends, it acts downward on the connecting rod through the air cylinder, causing the connecting rod to act downward on the lifting column, and the lifting column to act downward on the blade, facilitating the blade to cut the strip-shaped film downward.
