Description

A kind of meltable particle of accumulation type

Technical field

The utility model is related to a kind of plastic grain, in particular to the modeling that a kind of aggregation is good, fusing uniformity is strong Material particle.

Background technology

The crust of cable is generally plastic material, and the different performance parameters to plastic material according to cable particular use have Different requirements.The technique that attached crust is wrapped when making cable is typically all to heat plastic grain in electric wire extruder to be fused into Viscous pastes, then by pastel from outer wrap on core, cooling become cable.Utility model patent 201620133598.6 and 201620133767.6 disclose a kind of plastic grain, and original solid plastic particle is transformed into Through hole is left in centre, and surfaces externally and internally sets various fluctuatings to increase surface area, to improve its meltdown property.But experiment Confirm, this particle inner surface and outer surface in fusing are first melted, then internal re-melting, the fusion process time is more long, melts Change lack of homogeneity, if this shape is used for into cable plastics, cable skin is produced bubble or residual when wrapping attached Non- fusant and produce incrustation, so as to greatly damage its insulating properties.Additionally, existing plastic grain is dispersed strong each other, it is not easy to Mutually involve together, it is easy during filler in use mutually dispersion and the outward situation of flash occur.

Utility model content

The purpose of this utility model is to provide a kind of meltable plastic grain of accumulation type, and the plastic grain fusion process compares Short, fusing uniformity is good, is difficult to remain not tolerant, and mutually involves shape by force, and easily aggregation, is not in flash feelings during filler Condition.

To achieve the above object, the utility model takes following technical scheme：

A kind of meltable particle of accumulation type, including spherical particle block, the spherical particle block is by the first hemisphere and the second hemisphere Overlapped with the centre of sphere and be combined into, the radius of the radius less than the second hemisphere of the first hemisphere is evenly distributed with modeling on the first hemisphere Material cone, the plastic cone bottom is located on the sphere of the first hemisphere, and top is positioned at the complete ball where the second hemisphere On face, plastic cone cylinder is evenly distributed with the second hemisphere, the plastic cone cylinder top is connected with the second hemisphere, moulds Expect that the height of conic tube is equal to the height of plastic cone.

Preferably, the distance between two neighboring plastic cone is not less than the plastic cone on first hemisphere Base diameter.

Preferably, the height of the plastic cone is the 1/3 ~ 1/2 of the radius of first hemisphere.

In above-mentioned technical proposal, particle bodies are divided into two hemisphere for differing in size, and set in big hemisphere surface Conic tube, small hemisphere surface sets cone, and when so different particles contacts with each other, cylinder is readily inserted in conic tube It is interior, so as to be between particle it is inter-adhesive.In melted by heat, small hemisphere and cone burn-off rate thereon are closer to most The burn-off rate of ball and conic tube thereon, makes whole particles fuse speed ratio more uniform, effectively prevent residual not tolerant. Incrustation and the generation of bubble are decreased simultaneously, insulating properties are enhanced, and improve cable total quality.

Brief description of the drawings

Fig. 1 is the utility model structural representation.

Specific embodiment

Below in conjunction with the accompanying drawings, the utility model is described further：

As shown in figure 1, the meltable particle of this accumulation type has spherical particle block, spherical particle block is by the first hemisphere 1 and second Hemisphere 2 is overlapped with the centre of sphere and is combined into, the radius of the radius less than the second hemisphere 2 of the first hemisphere 1, uniform on the first hemisphere 1 Plastic cone 3 is distributed with, the height of plastic cone 3 is generally the first hemisphere 1/3 ~ 1/2, and the bottom of plastic cone 3 On the sphere of the first hemisphere 1, top is extended in the complete sphere for being formed by extension in other words where being located at the second hemisphere 2, Namely first the radius of hemisphere be exactly equal to the radius of the second hemisphere plus the height of plastic cone.On the second hemisphere 2 Even that plastic cone cylinder 5 is distributed with, the top of plastic cone cylinder 5 is connected with the second hemisphere, and opening 4 is left in bottom, and the opening can To be enclosed within the plastic cone of another particulate mass, adhesion degree is involved with strengthen variable grain block diameter, be easy to packaging And pan feeding.And the height of plastic cone cylinder is equal to the height of plastic cone.Described plastic cone and plastic cone Cylinder is dispersed, refers to being spaced on respective sphere and uniformly scatters, and be connected two modelings on the first general hemisphere Expect that the distance of cone diameter is not less than plastic cone base diameter, can so leave enough spaces another preferably to allow The plastic cone barrel jacket of individual particle is on plastic cone.

The present embodiment is the explanation that the utility model is conceived and realized, is not limited, in this reality With under new design, the technical scheme without essence conversion is still in protection domain.
