Outer protective cover of drying cylinder glue applicator

Abstract

The invention discloses an outer protective cover of a drying cylinder glue applicator, and belongs to the technical field of papermaking machinery. By the aid of the outer protective cover, the technical problems of incapability of quickly shifting existing glue applicators in or out of protective covers, tedious glue applicator breakdown maintenance working procedures, heavy equipment and influence on maintenance progress in the prior art can be solved. The technical scheme includes that a T-shaped open groove I is formed in the top of an outer protective cover body, and a T-shaped seal plate is movably arranged in the T-shaped open groove I; an opening door is arranged in the center of a side surface of the outer protective cover body, and the top of the opening door is correspondingly connected with the T-shaped open groove I; an open groove II is formed in the bottom of a side surface of the outer protective cover body, and a lifting cover wall which is matched with the open groove II is arranged at the open groove II. The outer protective cover has the advantages that the glue applicator can be quickly shifted in or out of the outer protective cover, accordingly, maintenance can be facilitated, and leakage can be prevented.

Description

technical field [0001] The invention relates to the technical field of papermaking machinery, in particular to an outer shield of a drying cylinder sizing machine. Background technique [0002] The drying cylinder is a hollow cylinder made of cast iron with covers at both ends. It is composed of a cylinder body and cylinder covers at both ends. During operation, the conveyed paper is dried and ironed by internal steam. The cast iron dryer cylinder for paper machine is a key component for paper drying. The function of the dryer is to use hot air to dry the moisture in the paper sheet. The whole system needs to complete the drying of the paper sheet through heat exchange to achieve the goal of finishing paper. purpose of the page. [0003] A closed space is required for drying, and the drying system of the existing paper machine is usually closed by an air hood; for example, the patent 201720073341.0 is named "a paper machine for producing plastic paper", and the technical so...
