Description

Technical Field

[0001] The utility model belongs to the technical field of tape production, and particularly relates to a particle melting device for tape production. Background Art

[0002] A tape is a strip material composed of a base material and an adhesive layer, and realizes the connection or fixation of objects through adhesion. According to materials, uses and characteristics, tapes can be divided into various types, such as transparent tapes, double-sided tapes, insulating tapes, waterproof tapes, warning tapes, cloth-based tapes, masking tapes, etc. During the tape production process, plastic particles for producing tapes need to be heated and melted to be converted into a film structure.

[0003] The existing authorized publication number is CN211586519U, which discloses a particle melting device for hot melt adhesive production, including a melting tank and a fixed base. One side of the top of the melting tank is communicated with a feeding funnel. A servo motor is installed at the middle position of the top of the melting tank. The output end of the servo motor is connected with a rotating shaft through a coupling. The rotating shaft penetrates through the top of the melting tank and is rotationally connected with the melting tank. Stirring rods are welded on the circumference of the rotating shaft. A heat conducting plate is arranged at the bottom of the melting tank below the stirring rods. A receiving groove is opened inside the melting tank below the heat conducting plate. A heating plate is installed inside the receiving groove. A first fixing block is welded at one end of the lower surface of the melting tank. The utility model heats and melts raw material particles through the heating plate, and drives the rotating shaft to rotate through the servo motor. The rotating shaft drives the stirring rods to rotate, and the stirring rods stir the raw material particles, thereby increasing the melting speed and making the melting more sufficient. However, the above-mentioned particle melting device for hot melt adhesive production installs the discharge pipe on the left side of the melting tank. After the raw material particles are heated and melted, the melting tank needs to be tilted to discharge the molten raw material particles from the melting tank. There is a risk of the melting tank collapsing during this process, thus posing a safety hazard to on-site operators. Therefore, it is necessary to provide a particle melting device for tape production to solve the above problems. Content of the Utility Model
