Paper barrel opening edge reeling machine

Abstract

The invention discloses a paper barrel opening edge reeling machine. A motor is in transmission connection with a central shaft which is horizontally arranged; a bend mold is arranged on the central shaft; a concentric arc groove is formed on an outer plane of the bend mold; and convex ribs are uniformly distributed in the arc groove. The arc groove is provided with an edge reeling control disc correspondingly; the edge reeling control disc is provided with an arc which is arranged opposite to the arc groove; the arc and the arc of the arc groove together form a device which can clamp and limit the barrel opening edge reeling; the edge reeling control disc is fixed on a frame; and the other end of the frame is provided with a barrel clamping device which is arranged opposite to the bend mold. The paper barrel opening edge reeling machine solves the problem that main parts are easy to abrade and need to be repaired and replaced after reeling edges of eight to ten thousands of paper barrel openings, so that the peripheral height error of the paper barrel opening edge is smaller, and the barrel opening edge is tighter, more circular and smoother.

Description

technical field [0001] The invention relates to a barrel lip curling device used in the production process of a full paper barrel. Background technique [0002] At present, some manufacturers who produce all-cardboard barrels use a hydraulic press to install a round iron mold on the top of the barrel mouth during the production process. On the lower plane of the iron plate, there is a The arc-shaped arc groove ring of the car, the semi-finished barrel produced is placed upright under the mold with arc groove, the circular arc groove is aligned with the mouth of the barrel, start the press, press down, so that the periphery of the barrel mouth The inner whole rim and barrel mouth rim are formed by hydraulic pressing. The disadvantages of using this equipment to carry out the inner beading of the barrel mouth are: 1. The inner beading of the barrel mouth is integral and at the same time, the force on the barrel body is particularly large, so the wall of the barrel is slightly...

AI Technical Summary

Problems solved by technology

The disadvantages of using this equipment to carry out the inner beading of the barrel mouth are: 1. The inner beading of the barrel mouth is integral and at the same time, the force on the barrel body is particularly large, so the wall of the barrel is slightly thicker, or the production task is too late When the drying barrel is a little wet, the bottom of the barrel will be crushed and crushed, resulting in a certain amount of waste in the production process of the paper barrel, and 90% or even 100% of the non-rejected paper barrels have large or small feet on the outer bottom of the barrel. The small ones have creases and wrinkles that are crushed by the seat, which not only affects the appearance of the paper drum, but more importantly, reduces the compression and stacking strength of the paper drum

2. The mouth of the barrel should be brushed with liquid adhesive before rolling the edge, making the inside of the barrel unhygienic and unsightly

However, if the adhesive is not applied, after the mouth of the barrel is forced to roll inward, it is easy to bounce back, the edge becomes soft, unsightly, and the strength is even worse

3. If the body of the barrel is a little higher, the edge should be rolled a little more, so that the edge of the mouth of the barrel runs down the wall of the barrel, and the mouth of the barrel is neither beautiful nor strong.

The disadvantages are: the elbow control pin used is easy to wear; the edge of the barrel mouth is easily scraped by the elbow control pin, and waste paper is easy to be scraped, and the fine dust of paper increases, which is unsanitary when it falls into the barrel; high error
