Description

A plastic strip granulator

technical field

The utility model relates to a granulator, in particular to a plastic strip granulator.

Background technique

Plastic pelletizer is an important equipment in the plastic production process. It can pelletize plastic strips to facilitate later storage and processing. The existing pelletizer cutter wheel and hob are integrated structure, and some hobs are also The long plate-shaped blade and the roller separation structure are adopted. After long-term use of this structure, when the local blade wears and collapses, the entire cutting roller or the entire blade needs to be replaced, and the rest of the cutter wheel and the blade are often It is very wasteful to replace those that can continue to be used; in addition, the conveying rollers used in the conveying of today's granulators can only perform basic pulling movement, and the strips are easily shaken or transversely caused by the cutting force at the end during the movement process. Offset, this not only makes the shape of the plastic pellets different after cutting, but also easily contacts and squeezes with other strips, making the transportation of the strips very disordered; the pelletizer generally cuts the strips into small pieces of particles, and then cuts the strips into small pieces. The large amount of plastic chips produced in the process is also a very good raw material for plastic processing. Its melting processing is easier than that of pellets. Nowadays, the plastic pellets and plastic chips of the pelletizer are mixed together when they are discharged, and they need to be separated separately later to avoid When processing together, due to the different particle sizes, the melting speed is different under the same conditions. It is difficult to process when the particles and debris are mixed, which is not conducive to the processing plasticity of plastics.

detailed description

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

Please refer to Figure 1-3, a kind of plastic strip granulator, including a conveying box 1, a granulating box 2 and a screening box 3, the right end of the conveying box 1 communicates with the left end of the granulating box 2, and the conveying box 1 is fixed inside Conveying plate 4 is connected, and conveying roller 5 and compacting roller 6 are also rotatably connected in conveying box 1. The rotating shaft is connected through gear meshing and is connected with the transmission motor. The granulation box 2 is connected with a cutting roller 7 in rotation. The surface of the cutting roller 7 is provided with a plurality of blades 8. The cutting roller 7 is connected with the cutting motor. The upper end surface of the plate 4 is fixedly connected with some guide strips 9, the roller surface of the conveying roller 5 is fixedly connected with some guide rings 10 corresponding to the guide strips 9 one by one, and the roller surface of the compacting roller 6 is fixedly connected with several The pressing ring 11, the pressing ring 11 and the material guide ring 10 are arranged alternately, and the plastic material strip is pushed into the conveying box 1 from the feeding port so that it is in the sub-groove between the material guide strips 9 and continuously pushed to make the material strip Arrive at the conveying roller 5, press and rotate the material strip through the conveying roller 5 and the compacting roller 6 so that the plastic material strip is transported on the conveying plate 4, the plastic material strip is located in the groove between the guide strips 9, and the compression ring 11 Pressing the material strips can make the material strips in a separated state during transportation without affecting each other.
