Description

Technical Field

[0001] The utility model relates to the field of pelletizing devices, and more specifically to a pelletizing device for producing polymer plastic particles. Background Art

[0002] When polymer plastic particles are produced, after the pelletizer cuts the strip extruded material into pellets, it is usually necessary to screen the particles using a vibrating screen, which can not only remove impurities and unqualified products, but also grade the particles according to specifications to ensure that the product quality meets the expected requirements.

[0003] The existing pelletizing device may cause the plastic particles to bounce when dropping due to the violent vibration or uneven cutting during the cutting process, which makes the material dropping inconvenient. And when the plastic particles fall into the subsequent vibrating screen through the discharge port, due to the excessive speed or the influence of other external factors, some particles may jump or fly out, causing the material to splash and waste, which not only affects the production efficiency, but also increases the complexity of the cleaning work and increases the production cost. In addition, there is a phenomenon that the material is blocked around the discharge port during the material dropping, which makes the material dropping inconvenient and affects the continuity and efficiency of production. Utility Model Content

[0004] The utility model aims to overcome the defects of the prior art and provides a pelletizing device for producing polymer plastic particles.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pelletizing device for producing polymer plastic particles, comprising a frame, a shell installed on the frame, a feed bin fixedly connected to the shell, a feed rotating shaft installed in the feed bin, two conveying rollers installed in the shell, a cutting roller installed in the shell and a discharge bin fixedly connected to the shell, the top of the shell having a top cover, the shell having a cutting roller driving unit capable of driving the cutting roller to rotate and a conveying roller driving unit capable of driving the two conveying rollers to rotate installed, the feed bin having a feed port, the surface of the cutting roller having a plurality of cutting blades, the discharge bin having a discharge port, the discharge bin having an end cover capable of surrounding the discharge port, the end cover having a flexible cloth tube fixedly connected, the bottom of the end cover having two support plates for supporting the flexible cloth tube, the ends of the support plates having an end arc plate fixedly connected, and a counterweight rod being installed between the two end arc plates.

[0006] Furthermore, a row of partition baffles is fixedly connected to the feed shaft, and an extruded strip can be easily placed between two adjacent partition baffles.

[0007] Thus, the separation baffles are used to separate and avoid confusion among multiple extruded strips.

[0008] Furthermore, the axes of the two conveying rollers are located on the same vertical line.

[0009] This ensures that the raw materials remain stable during transportation.

[0010] Furthermore, the plurality of cutting edges are distributed in a ring shape with equal intervals.

[0011] Thereby, the raw materials are cut into particles evenly.

[0012] Furthermore, the housing has a first bearing matched with the cutting roller and a second bearing matched with the conveying roller.

[0013] Thereby the cutting roller and the conveying roller rotate more smoothly.

[0014] Furthermore, the end cover is fixedly connected to the discharge bin via a first locking bolt, and the first locking bolt passes through the end cover and tightens against the discharge bin.

[0015] Therefore, the flexible cloth tube is easy to disassemble and assemble, and is convenient for maintenance.

[0016] Furthermore, the counterweight rod is fixedly connected to the end arc plate by a second locking bolt, and the second locking bolt passes through the end arc plate and presses against the counterweight rod.

[0017] Thereby, it is convenient to install and fix the counterweight rod.

[0018] Furthermore, two handles are fixedly connected to the top of the top cover.

[0019] Therefore, the top cover can be opened conveniently, thereby facilitating maintenance and operation of the interior of the shell.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. The pelletizing device of the present application allows the extruded strip to be pelletized by the cutting blade and then discharged from the flexible cloth tube, thereby making the discharge more convenient and easier to cooperate with the subsequent vibrating screen. In addition, due to the limitation of the flexible cloth tube, the material will not bounce when the material is discharged.

[0022] 2. In the pelletizing device of the present application, the support plate plays a certain supporting and limiting role on the flexible cloth cylinder, so that it maintains a certain shape, thereby facilitating material unloading, and the counterweight rod enables the end arc plate to abut against the vibrating screen, so that the vibration of the vibrating screen is transmitted to the flexible cloth cylinder, causing a small vibration to the flexible cloth cylinder, thereby making material unloading more convenient.

[0023] 3. The top cover of the pelletizing device of the present application is easy to open, so that the internal parts can be maintained and operated, which improves the overall convenience and efficiency of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Working principle: In the pelletizing device of the present application, the extruded strip is fed from the feed port, guided to between two conveying rollers by the feed shaft, and then conveyed to the cutting roller by the conveying roller, and then cut into particles by the cutting blade. The plastic particles are dropped into the flexible cloth tube through the discharge port, so that the material is more convenient to drop, and it is easier to cooperate with the vibrating screen, which improves the continuity and efficiency of production.
