Semi-automatic paper bag bottom pasting machine

Abstract

The invention provides a semi-automatic paper bag bottom pasting machine comprising a paper bag feeding mechanism. The paper bag feeding mechanism is sequentially provided with bag bottom spreading mechanisms, an adhesive spraying mechanism and a bottom pasting and compacting mechanism according to the paper bag advancing sequence. The bag bottom spreading mechanisms are symmetrically arranged onthe two sides of the upper portion of a feeding channel. Each bag bottom spreading mechanism sequentially comprises a spreading mechanism and an initial compacting mechanism which are sequentially installed on a bag bottom spreading machine frame. The paper bag feeding mechanism comprises a feeding base, feeding support plates and a feeding clamping mechanism. The bottom pasting and compacting mechanism comprises bottom pasting and compacting supporting plates, a bottom pasting and compacting installation plate, a bottom pasting mechanism and a compacting mechanism. The semi-automatic paper bag bottom pasting machine is novel in structure, production and manufacturing are convenient and rapid, and batch bottom pasting and compacting of paper bags can be achieved through a low production cost; in the bottom pasting and compacting process, a reinforcing paper sheet is accurately pasted to the bottom of the paper bag, press fitting and compacting of the reinforcing paper sheet are conducted, and therefore the production quality of the paper bag is guaranteed; and operation is stable, and the semi-automatic paper bag bottom pasting machine is suitable for use and popularization among small and medium-sized enterprises.

Description

technical field [0001] The invention belongs to the field of packaging equipment, and in particular relates to a semi-automatic bottom paste machine for paper bags. Background technique [0002] Traditional paper bag processing needs to go through two processes of tube making and bottom paste, while the current bottom paste process is generally completed manually or by machine. Although artificial bottoming can ensure the quality of paper bag bottoming, the efficiency is low; although machine bottoming can effectively increase the speed of bottoming, it is difficult to ensure that the reinforcing paper is accurately attached to the bottom of the paper bag, resulting in paper bag bottoming The quality is poor and affects the appearance. At the same time, although imported bottom paste machines can not only increase the speed of bottom paste, but also ensure the quality of bottom paste, due to their high purchase and maintenance costs, it is difficult to promote their use in s...
