Tongue inserting mechanism for packing box

Abstract

A tongue inserting mechanism for a packing box is mainly composed of a tongue folding knife, a connecting rod, a tongue inserting knife, an active crank block, a slave crank block, two supports, an active shaft, a slave shaft, synchronous belt pulleys, a synchronous belt, a bevel gear and the like. The tongue folding knife and the tongue inserting knife are located on the top of the tongue inserting mechanism for the packing box and fixed to the connecting rod. The two ends of the connecting rod are connected with the active crank block and the slave crank block correspondingly which are same in size and form a parallelogram mechanism. The supports are parallelly mounted. The active shaft and the slave shaft vertically penetrate through the supports, and the axes of the active shaft and the slave shaft are parallel. The synchronous belt pulleys are mounted on the active shaft and the slave shaft correspondingly. The synchronous belt is mounted on the synchronous belt pulleys. The bevel gear is fixedly connected with the bevel gear on the active shaft and located below the device. The axial direction of the bevel gear is the perpendicular direction. The structure is simple, the mechanical action time of tongue inserting is reduced, the mechanical action range and occupied space are small, and the speed of the tongue inserting process is increased.

Description

technical field [0001] The invention relates to the technical field of packaging equipment, in particular to a tongue-inserting mechanism for a packaging box. Background technique [0002] For boxes of the type locked by tongue insertion, the tongues have tongues at the top of the front wall and / or at the front of the lid, or also side tongues. Tongue insertion is more difficult for machinery to complete. In the past, most of them were done manually. For example, with machinery, many power-driven mechanisms were used to press and fold the corresponding parts. In this way, the mechanical structure is relatively large and these power-driven mechanisms need to occupy a considerable space for movement. [0003] Chinese invention patent (application number 201410579193.0, application date 2014.10.24) discloses a side tongue mechanism for a shoe box folding machine, including a side plate reduction motor, a side plate crank, a side plate connecting rod, and a side tongue mechanis...

Problems solved by technology

In the past, it was mostly done manually, such as using machinery, and many power-driven mechanisms were used to press and fold the corresponding parts. In this way, the mechanical structure is relatively large and these power-driven mechanisms need to occupy a considerable amount of movement space.
