[0003] The existing pvc plastic granule is usually solid structure, in the process of entering the injection molding machine melting, the surface area of plastic granule is smaller than that of the same volume of plastic powder, so the heated area of contact with hot air in the melting cavity is smaller, the melting speed is slower, there is surface melting, internal has not completely melted, the plastic granule that has not completely melted directly enters the mold, easy to affect the processing quality of plastic product. UTILITY MODEL CONTENTS
[0004] The utility model discloses a kind of easy to melt pvc plastic granule, to solve the existing pvc plastic granule usually solid structure in the above background technique, in the process of entering the injection molding machine melting, the surface area of plastic granule is smaller than that of the same volume of plastic powder, so the heated area of contact with hot air in the melting cavity is smaller, the melting speed is slower, there is surface melting, internal has not completely melted, the plastic granule that has not completely melted directly enters the mold, easy to affect the processing quality of plastic product.
[0005] To achieve the above object, the utility model provides the following technical scheme: including granule body;The granule body includes inner layer granule and outer layer granule, two connecting columns are arranged between the inner layer granule and outer layer granule, the entering cavity is formed between the inner layer granule and outer layer granule, and the middle part of the inner layer granule is transversely provided with a through port.
[0006] Preferably, a plurality of second grooves are annularly arranged in the inner side of the outer layer granule.
[0007] Preferably, a plurality of first grooves are annularly arranged in the inner side of the inner layer granule.
[0008] Preferably, the number of the first grooves and the second grooves is respectively one.
[0009] Preferably, the length of the granule body is less than or equal to 10 mm.
[0010] Compared with the prior art, the beneficial effects of the utility model are that: through the combination of the annular shape of the inner layer particles and the outer layer particles into the particle body, the heat can be contacted with the particle body fully, the first groove and the second groove can improve the melting effect of the inner layer particles and the outer layer particles respectively, under the condition of sufficient particle body quality, the particle body can be melted fully, the particle body melting effect is ensured, and the influence on the plastic product forming quality is avoided.
