Description

Technical Field

[0001] The utility model relates to the technical field of paper tube production, in particular to a raw material crushing device for paper tube production. Background Art

[0002] Paper tubes are tubular objects made of paper. Most paper tubes are spiral paper tubes and seamless paper tubes. Paper tubes are widely used in many industries, such as chemical fiber, film, printing, papermaking, metallurgy and other industries. Paper tubes refer to tubular objects made of paper. Paper tubes can be divided into spiral paper tubes and seamless paper tubes. They are mainly used in chemical fiber, film, printing, papermaking, metallurgy and other fields. In the production and processing of paper tubes, wood is used as raw material, the wood is crushed into wood pulp, and the wood pulp is processed into paper, so crushing equipment is required.

[0003] The existing raw material crushing equipment for paper tube processing cannot quickly separate the raw materials that meet the size standards during the crushing process, and the crushing efficiency is low;

[0004] The existing patent (publication number: CN210458751U) is a raw material crushing equipment for paper tube processing. The first driving motor, the first rotating shaft, the driving wheel, the driven wheel and the first crushing knife group constitute a primary crushing mechanism. The raw material powder is graded by the inclined filter plate and the second filter screen. The powder that meets the size standard falls directly and is discharged along the second discharge port. The powder that does not meet the size standard enters the second crushing shell along the filter plate. At the same time, the support mechanism of the filter plate is composed of the first support rod, the spring, the second support rod and the mounting seat. The spring expands and contracts with the gravity change of the falling raw material powder, so that the filter plate vibrates to prevent the raw material powder from accumulating on the filter plate. The second driving motor, the second rotating shaft, the spiral blades and the second crushing knife group constitute a secondary crushing mechanism. The spiral blades drive the raw material to move from left to right, and the second crushing knife group performs secondary crushing on the raw material.
