High-speed paper carton forming device

Abstract

The invention relates to a high-speed carton molding machine. The high-speed carton molding machine comprises a mainframe part, a pusher part and a stacking supply part; the mainframe part comprises a cut paper transporting component, an unpacking molding component, a box retaining and positioning component, a gelatinization component, an outer foldout component, a box discharging and dropping component, a box pressing and molding component relatively arranged at one side and an upper box poking and adjusting component; the box pressing and molding component comprises two small circulating guide rails in parallel arrangement, a circulating transmission chain, a sliding guide rail, a box pressing component and a large circulating guide rail; the sliding guide rail is vertically arranged between two small circulating guide rails and is connected with the circulating transmission chain; two ends of the sliding guide rail are connected with tracks of two small circulating guide rails through slide blocks respectively; the bottom end of the box pressing component is arranged on the sliding guide rail through a sliding sleeve; the upper side of the box pressing component is connected with a track of the large circulating guide rail through an idler wheel; and the large circulating guide rail is provided with a section of a bended convex track. The high-speed carton molding machine has a compact structure, high carton molding speed, small vibrating strength and noise and large carton storage capacity.

Description

technical field [0001] The invention relates to the field of packaging machinery, in particular to a carton forming machine which performs high-speed automatic unfolding, edge folding, gluing, and bottom sealing of carton blanks that have been folded into double-layer flat cardboard before leaving the factory. Background technique [0002] Secondary packaging for bottled or canned items is usually done in corrugated boxes. In order to facilitate transportation, reduce volume and save cost, the cartons shipped by the carton factory are usually stacked into double-layer cardboard; the front, back, left and right sides of the carton are interconnected in turn; It consists of horizontal folding, upper vertical folding, lower horizontal folding and lower vertical folding. During delivery or storage, each flap is on the same plane as the front, rear, left, and right sides, and the flaps are not connected due to cutting seams, so that each flap can be aligned with the front, back,...

AI Technical Summary

Problems solved by technology

[0005] There are many types of existing general carton forming machines. According to the needs of forming operations, its main mechanisms include feeding devices, unpacking devices, lid folding devices, gluing devices, and box pressing devices. 1. The feeding device There is a cardboard material warehouse and a cardboard layering device. Manually place the cardboard to the working position, and use the vacuum suction cup to hook the cardboard into the next working position. This structure can store a small amount of cardboard to be formed, and it is necessary to add cardboard. The density is high, which reduces the work efficiency and increases the labor intensity; 2. The unpacking device has a lifting swing arm group, and its structure has one end of a pair of parallel connecting rods connected to the machine table, and the other end is connected to a suction cup. Then use the cylinder to push the parallel connecting rod to swing so that the suction cup can maintain a horizontal lift, so that it can suck the top surface of the
