Description

Technical Field

[0001] The utility model relates to the technical field of PE production, in particular to a convenient heat cutting machine. Background Art

[0002] PE protective film is the simplest macromolecular organic compound and the most widely used macromolecular material in the world today. PE protective film uses special polyethylene (PE) plastic film as its substrate and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to different densities. The existing hot cutting machines for PE film processing have too high a temperature at the cutting point during cutting, which causes the film to deform when in contact with the film, resulting in film loss. At the same time, during the cutting process, the film is easily stuck in the cutting seam, which requires manual time to organize, and cannot meet people's usage needs well.

[0003] After searching, a hot cutting machine for PE film processing disclosed in the prior art (application number: CN202020435306.0) records that "a rotating roller is arranged at the right end of the main roller, and a supporting frame is arranged at the right end of the rotating roller, a heating plate is arranged inside the supporting frame, and a hydraulic pump is arranged in the middle of the heating plate, a cutting blade is arranged at the lower end of the hydraulic pump, and a base is arranged below the cutting blade, a middle plate is arranged in the middle of the base, and a spring is arranged at the lower end of the middle plate, a slide is arranged at the right end of the auxiliary roller, and the auxiliary roller is located at the right end of the supporting frame, a groove is arranged in the middle of the slide, and a bearing roller is arranged inside the groove, a telescopic rod is arranged at the right end of the bearing roller, and a handle is arranged at the upper end of the telescopic rod, and the front end of the handle is arranged The hot cutting machine is provided with a motor, and a belt is provided at the front end of the motor, and a pulley is provided inside the belt. "; The hot cutting machine is provided with a hydraulic pump, a cutting blade, a middle plate and a spring. The main purpose of the structure is that the beveled blade of the cutting blade reduces the contact area between the cutting blade and the PE film and improves the cutting effect. At the same time, the middle plate rises and falls with the contact of the cutting blade to prevent the cut PE film from falling into the cutting seam and affecting the operation of the device. However, the setting of the middle plate can prevent the PE film from falling into the cutting groove, but it will also increase the passivation speed of the cutting blade, thereby resulting in insufficient sharpness of the cutting blade, which will then prolong the time required for hot cutting of the PE film, resulting in poor quality of the cut surface of the PE film, and will also increase the probability of the PE film adhering to the surface of the cutting blade, and the loading and unloading process of the cutting blade is not convenient enough.

After the cutting knife is heated to a suitable temperature, the switch of the cylinder 12 is started, and the multi-stage telescopic rod of the cylinder 12 pushes the fixedly connected moving plate 7 to move downward, and the moving plate 7 drives the cutting assembly 6 to move synchronously through the clamping plate 9, so that the inclined surface of the cutting knife can push the heating assembly 3 to move into the buffer groove 17 to squeeze the corresponding spring during the downward movement, and when the blade of the cutting knife contacts the PE film, the heating assembly 3 contacts the surface of the cutting knife through the insulation board 15, thereby reducing the heating effect of the cutting knife and avoiding overheating of the cutting knife.
