Description

Technical Field

[0001] The invention relates to the technical field of preparation of plastic particles, in particular to a plastic particle processing machine and a plastic particle processing method. Background Art

[0002] Plastic granules are formed by thermoplastic molding to regenerate plastic into granules, which improves the recycling rate of plastics. In the processing of thermoplastic plastics such as regeneration and modification of plastic raw materials, extrusion granulation has the characteristics of simple operation, high degree of automation, and uniform granulation, making it one of the preferred methods.

[0003] Usually, in the process of preparing plastic particles, a granulator is needed for preparation. Its working principle is as follows: the thermoplastic plastic is heated to become a molten state, and is extruded and transported by a screw in a metal barrel through a metal perforated plate at the end of the barrel. A scraper rotating at a certain speed is arranged on the outside of the metal perforated plate to cut the molten plastic extruded through the hole, and at the same time, a refrigerant such as cooling water is used to quickly cool and shape the granulated plastic to prevent sticking. In the process of extruding and cutting the plastic particles into particles, the particles will fall into the water. When adjacent particles fall at the same time, the particles will stick together before falling into the water. When the particles fall into the water, potential energy will be generated when the particles come into contact with water, which will cause the shape of the particles to change, thereby affecting the product quality. For this reason, we propose a plastic particle processing machine and a plastic particle processing method. Summary of the invention

[0014] A plastic pellet processing method of a plastic pellet processing machine comprises the following steps:

[0015] Step 1: Inject the plastic granule preparation raw material into the interior of the molding box through the feed pipe, and use the heating plate to heat the material inside the molding box, and start the motor installed on the upper end of the rotating column;

[0016] Step 2: The rotating column drives the mounting plate and the stirring rod to rotate, and the mounting plate and the stirring rod mix and stir the plastic material, and at the same time stir and melt the raw material to the inside of the conical funnel, and when the first spiral blade rotates, the first spiral blade squeezes and pushes the raw material to the inside of the feeding pipe;

The plastic pellet processing machine and the plastic pellet processing method are characterized in that the raw materials are placed in a molding box, and the molding box simultaneously stirs, heats and melts the raw materials, and the processed raw materials are compressed and directly placed in a cooling device. The cooling device ensures the yield of the pellets after molding, avoids the high temperature contained in conventional pellets after preparation, resulting in the pellets being unable to be molded, and requires auxiliary processing such as cooling and solidification in the later stage, thereby ensuring that the pellets can be prepared and molded in one time and reducing the working cost.

The plastic pellet processing machine and the plastic pellet processing method are characterized in that a heating plate is installed inside the molding box, and a stirring device is installed between the heating plate and the connecting plate. The heating plate rotates synchronously with the stirring device to improve the heating efficiency, and the mounting plate can fully mix and stir the passing materials to reduce defects and prevent the raw materials from adhering to the heating device, which affects the heating efficiency.

[0023] 3. The plastic pellet processing machine and the plastic pellet processing method can control the alignment of different apertures by adjusting the adjustment seat, and improve the convenience of adjusting the pellets by conveying the raw materials to the inside of the molding pipes with different apertures. At the same time, the second spiral blade drives the cutter to rotate synchronously through the connecting column, that is, the speed of the extruded pellets is kept the same as the cutting speed of the cutter, ensuring that the pellet size remains uniform after cutting.

Three groups of second feeding holes 164 are opened inside the adjustment gasket 162, and the second feeding holes 164 are aligned with each other. By rotating the adjustment gasket 162, the holes between the first feeding holes 163 and the second feeding holes 164 are controlled to be aligned and installed. After the different holes are aligned, the raw materials can be extruded through the different holes, so that plastic particles of different sizes can be prepared according to different requirements for preparing particles.

The first spiral blade 6 is fitted on the inner side of the conical funnel 2. The raw material can be put into the interior of the molding box 1 through the feed pipe 4, and the raw material is stirred and prepared. At the same time, the first spiral blade 6 is installed at the lower end of the rotating column 5. During the rotation of the first spiral blade 6, the raw material can be squeezed to reduce the voids contained in the raw material after preparation, which affects the quality of the particles.

At the same time, the connecting plate 8 drives the mounting plate 10 and the stirring rod 11 to rotate, which can stir the raw materials accumulated inside, thereby improving the adequacy of the material stirring, and a heating device is arranged on the inner side of the heating plate 7 to ensure that the heating device can rotate and heat inside the molding box 1, thereby improving the more sufficient heating of the raw materials.

[0037] See also Figure 2 A second spiral blade 13 is installed inside the feed pipe 12, a sealing sleeve 24 is fixedly connected to the middle of the condensing device 17, a connecting column 22 is installed inside the sealing sleeve 24, and the connecting column 22 is installed inside the conical block 15, the condensing device 17 and the discharge port 21 in sequence.

[0038] See also Figure 2 A cutter 23 is fixedly connected to one end of the connecting column 22. The cutter 23 is fitted on the outside of the discharge port 21. At the same time, a discharge hole is opened on the outside of the discharge port 21. The cutter 23 is fitted on the outside of the discharge port 21.

[0039] See also Figure 2A feed pipe 19 is fixedly connected to one side of the upper part of the condensing device 17, and a water outlet pipe 20 is fixedly connected to one side of the lower end of the molding pipe 18.

That is, the inside of the molding pipe 18 can be cooled and molded to avoid the need for heating during raw material processing. After the particles are prepared, they need to be put into liquid for cooling and molding, which causes liquid to adhere to the outside of the particles and requires subsequent air drying and other processes, resulting in a waste of time.

After passing through the feed pipe 14 and the conical block 15, it can be evenly distributed inside the adjustment seat 16. At the same time, after diversion, the appearance of bubbles inside the raw material is reduced, which affects the product quality.
