Description

Template structure of rubber granulator

Technical Field

The utility model belongs to the technical field of rubber particle manufacture equipment technique and specifically relates to a template structure of rubber pelleter.

Background

A rubber granulator, namely a rubber granulator is equipment for producing rubber particles, and the main process is that molten rubber is extruded by a screw, rubber materials are extruded from small holes arranged on a front-end die head by the screw and then cut into particles by a cutter arranged in front of the die head, at the moment, a cooling device is used for spraying water for cooling rubber strips at the small holes, the structure of a cutting machine is different according to the difference of used raw materials or the difference of the performance requirements of the particles, for example, when the rubber is used in a cage, the function of rubber mixing and filtering needs to be enhanced, but the difference between the die head and the granulating device at the die head is not large, for example, the whole machine drawing of the granulator shown in the attached figure 1, the die head structural drawings shown in figures 2 and 3, the cutter head structural drawings shown in figures 4 and 5, the outer end surface of the die head is a plane, rubber outlet holes on the die head are circumferentially arranged, and the rubber strips, the rotary surface of the cutter edge on the cutter head is a plane attached to the end surface of the die head, and the shape of the glue outlet on the die head is determined by the shape required by the particles.

With the progress of the technology, rubber particles are required to be higher and higher in performance, natural rubber and/or rubber particles with excellent performance after being added with certain substances show stronger and stronger viscosity, and in this case, the rubber particles of the existing granulator are easy to be adhered after being cut, and the main reason is that: the particles do irregular motion after being cut off, the probability of mutual collision is high, the particles are adhered together once being collided due to high viscosity of the particles, and if the efficiency needs to be improved, the particles are more seriously adhered when the cutter head rotates at a high speed.

The adhered rubber particles affect the use performance of the particles and the quality of products.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the rubber discharging template used on the rubber granulator is provided, wherein the rubber particles are not easy to adhere after being cut.

The utility model provides a technical scheme that its technical problem adopted is: the template structure of the rubber granulator is characterized in that a fixing hole for installing the template on a discharge port of a granulator body and extrusion holes distributed with a plurality of rubber materials are arranged close to the central position of the template close to the periphery of the template, an arc-shaped concave cavity for accommodating a hob edge with a cylindrical rotating surface is formed in the front end surface of the template in a cutting mode according to the rubber outlet direction, and the extrusion holes are located in the arc-shaped concave cavity.

The hob shaft line is in a horizontal state, which is a structure that rubber particles can fall and are not adhered, so that the shaft line corresponding to the inner arc surface of the arc-shaped concave cavity is in a horizontal state when the template is in a use state.

Specifically, the extrusion holes are at least one row horizontally arranged, and the inner arc surface of the arc concave cavity enables the rubber particles after rolling cutting to fall along a parabolic track. The structure is easy to process the extrusion holes, and if the processing convenience is not considered, the extrusion holes are arranged in a wave shape, so that the scheme is also feasible.

In order to make the rubber particles less prone to adhesion during falling and improve the extrusion efficiency, the extrusion holes are horizontally arranged in an upper row and a lower row or more than the upper row and the lower row, and the extrusion holes which are adjacent to each other are arranged in a left-right staggered manner.

The utility model has the advantages that the template structure of the rubber granulator changes the prior conventional end plane granulating method into a circumferential rolling cutting method, the cut particles move in a parabolic regular manner, collision between the particles is not easy to occur, and adhesion between the particles is better prevented; the utility model discloses still have another beneficial effect, because the axis of arc cavity and hobbing cutter is perpendicular to screw rod axis, from each device overall arrangement of equipment, shortened the length size of equipment greatly.
