An automatic folding machine

Abstract

An automatic box bender is mainly characterized in that a short grid rotary shaft and a long grid rotary shaft are respectively arranged at two upper crossbeams of a rack; the two rotary shafts are respectively connected with the rotary shaft of a motor; the motor is connected with a control panel; a long grid is arranged at one end of the rack; a short grid is arranged in the middle of the rack; a support mechanism is arranged between the two grid rotary shafts; the support mechanism is provided with angle steel supports vertically connected with lower crossbeams; each angle steel support is provided with four parallel connection rods connected with a suction plate by a suction plate shaft; air inlets are formed in the upper panel on the suction plate; the lower panel of the suction plate is provided with air outlets connected with a vacuum system; the suction plate is provided with a limiting block provided with a sensor; the limiting block is connected with a PLC (programmable logic controller) single chip microcomputer arranged in the control panel; two torsion springs sleeve an inner support shaft; the corresponding ends of the torsion springs are arranged on connection rods of a four-rod mechanism; the other ends of the torsion springs are arranged at support plates under the angular steel supports; vertical spring limiting plates fixed on the two angle steel supports are respectively arranged on the angle steel supports. The automatic box bender is simple in structure, and the box bending cost can be greatly reduced.

Description

technical field [0001] The invention relates to a cardboard box folding equipment matched with a semi-automatic box gluer. Background technique [0002] With the development of social productive forces, corrugated cardboard boxes have become the most important form of transportation packaging in the packaging industry, and are widely used in the sales packaging of various products such as food, medicine, and electronics. Although its styles are increasingly diversified, the slotted corrugated cardboard boxes mentioned in GB6543-86 are still widely used because of their simple structure and flexible size. [0003] At present, the bonding work of basic corrugated cardboard boxes with fixed size and mass production is usually done by a special automatic or semi-automatic box gluer. Fully automatic folder gluer has a high level of automation, but has a complex structure and high cost. It is generally used in some large enterprises, while small and medium-sized enterprises mostl...

Problems solved by technology

On the one hand, the work intensity of the workers is high, and the monotonous repetitive work can easily lead to fatigue and safety accidents; Efficiency is largely determined by the worker whose short absence can stop the carton gluing work

[0004] The function of folding and sending the carton back to the production line of the existing equipment is mostly completed in separate structures. For example, the patent 201220546147.7 uses two sets of devices, the lifting component and the linear motion component, to realize the return of the carton, and uses more drives, while the patent 201120462012.8 uses the motor The vacuum suction cup on the crankshaft absorbs the two sides of the carton for folding, and the mechanical performance of the end of the motor shaft is not good.
