Core pulling die with automatic cleaning function

Abstract

The invention discloses a core pulling die with an automatic cleaning function. The core pulling die comprises a first central spindle, a second central spindle and a transmission assembly, wherein the second central spindle and the first central spindle are arranged in parallel along the same direction; a distance between the peripheral surface of the second central spindle and the peripheral surface of the first central spindle is less than 1 mm; the transmission assembly is connected with the first central spindle and the second central spindle respectively in a rotatable manner; and the transmission assembly can drive the first central spindle and the second central spindle to rotate towards the same direction. According to the core pulling die with the automatic cleaning function, as the distance between the peripheral surface of the second central spindle and the peripheral surface of the first central spindle is extremely short, mutual friction force is generated between the first central spindle and the second central spindle when the first central spindle and the second central spindle are attached with raw materials, so as to clear away the attached materials on the respective surfaces; and furthermore, the first central spindle and the second central spindle rotate 360 degrees, the whole surfaces of the first central spindle and the second central spindle can be completely cleaned. Compared with the prior art, the core pulling die has the advantage that the problem that a core pulling shaft is cleaned only after the die is stopped is solved, so that continuous production is realized, and the production efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of production of gypsum lightweight hollow partition wall boards, in particular to a core-pulling mould with automatic cleaning function. Background technique [0002] In the production process of the gypsum lightweight hollow partition wall board, after the mandrel has worked continuously for a period of time, the surface will adhere to the production materials, which will cause the mandrel to not rotate smoothly, and the surface attachment of the mandrel will lead to the outer diameter of the mandrel. The larger the diameter of the hollow hole in the finished product, the larger the product does not meet the standard, and the probability of defective products increases significantly. [0003] In order to solve the above problems, during the production process, it is necessary to stop the production at a certain interval, and clean up the attachments on the surface of the mandrel, and then continue to start the pr...

AI Technical Summary

Problems solved by technology

[0002] In the production process of gypsum lightweight hollow partition boards, after the core-pulling shaft has been working continuously for a period of time, the surface will adhere to the production raw materials, causing the core-pulling shaft to not rotate smoothly, and the surface attachment of the core-pulling shaft will cause the outer diameter of the core-pulling shaft to become larger, which in turn causes the diameter of the hollow hole in the finished product to become larger, making the product not up to standard, and the probability of defective products increases significantly

[0003] In order to solve the above problems, in the production process, the production must be stopped at a certain time interval, and the attachments on the surface of the core pulling shaft must be cleaned, and then the production will continue. In this way, the production continuity is affected and the production efficiency is reduced.
