Granulating device for cold and heat shrinking material of insulation joint

Abstract

The invention relates to the technical field of cold and heat shrinking material processing equipment and discloses a granulating device for a cold and heat shrinking material of an insulation joint.The granulating device comprises a granulating rack, wherein a seal cover is mounted at the top end of the granulating rack, a spindle is mounted in the middle of the upper end of the seal cover through a bearing pedestal, a raw material barrel is mounted at the bottom end of the spindle, a plurality of centrifugal holes are formed in the inner wall of the raw material barrel, the spindle is of ahollow structure, an auxiliary shaft is arranged in the spindle, a granulating barrel is mounted at the bottom end of the auxiliary shaft, a plurality of granulating holes are formed in the bottom endof the granulating barrel, a plurality of granulating cutters are mounted on the inner wall of the granulating barrel, a fixed plate is mounted at the bottom end of the inner wall of the granulatingbarrel, a discharge plate is connected to the upper end of the fixed plate through a buffer spring, a plurality of discharge holes are formed in the middle of the discharge plate, the right end of thedischarge plate is connected to a vibrating motor by a vibrating column, and a discharge hopper is mounted at the bottom of the granulating rack. According to the granulating device, the cold and heat shrinking material is granulated efficiently. By matching with the discharge plate, the granulated granules will not block the granulating device internally, so that the granulating quality is improved greatly.

Description

technical field [0001] The invention relates to the technical field of processing equipment for cold and heat shrinkable materials, in particular to a granulation device for cold and heat shrinkable materials for insulating joints. Background technique [0002] Cold and heat shrinkable materials Heat shrinkable materials, also known as polymer shape memory materials, are intelligent materials that combine polymer materials with radiation processing technology. Ordinary polymer materials such as polyethylene, polyvinyl chloride, etc. are usually linear structures. After being irradiated by electron accelerators and other radioactive sources, these materials will have a unique "memory effect". The material can re-shrink back to its original shape when heated. The memory properties of heat-shrinkable materials can be used to make heat-shrinkable tubing, film and profiled materials. The main feature is that the heat-shrinkable material is coated on the outer surface of the obje...

[0004] Chinese patent (Notice No. CN106881776A) discloses a granulation device for insulating joint materials, including: a granulation column cavity, characterized in that the inner cavity of the upper part of the granulation column cavity is provided with a molding cone that is nested together and pelletizing cone; several molding holes are arranged on the molding cone, and the molding holes are arranged to form several circles on several cross-sections of the molding cone; several cross-sections of the pelletizing cone are provided with There are several circles of grid holes; the position of a circle of forming holes on each cross-section corresponds to the position of a circle of grid holes on the same cross-section; the top of the forming cone and the cutting cone is provided with a tube body, and the tube body runs through The bottom of the granulation column cavity is open; the top of the granulation column cavity is also provided with at least one feeding pipe, although this device can achieve effective granulation of cold and heat shrinkable materials to a certain extent, However, in actual operation, the heat-shrinkable material after granulation is not only easy to agglomerate, but also blocked inside the granulation device, which seriously affects the granulation effect in the later stage. Therefore, further improvement is needed
