02-type duck tongue corrugated carton packaging machine

Abstract

A 02-type duck tongue corrugated carton packaging machine comprises a corrugated carton conveyor belt. A duck tongue guide board with an arc-shaped inner end face is mounted at the side end of the corrugated carton conveyor belt. The inner end face of the lower portion of the duck tongue guide board is provided with a strip-shaped groove. The width of the strip-shaped groove is greater than the thickness of the sidewall of a corrugated carton. The top face of the strip-shaped groove is located above the sidewall of the corrugated carton. A hold-down device moving up and down is arranged above the opposite side of the inner end face of the duck tongue guide board. According to the technical scheme, the sidewall of the corrugated carton is located in the strip-shaped groove; the duck tongue of a top board of the corrugated carton keeps drooping under limit of the arc-shaped groove; when the hold-down device moves downwards, the top board of the corrugated carton moves downwards to enable the duck tongue of the top board of the corrugated carton to go into a carton body of the corrugated carton. By adopting the 02-type duck tongue corrugated carton packaging machine, the working procedure that the duck tongue is pressed into the carton body is greatly simplified.

Description

technical field [0001] The invention belongs to product packing equipment when corrugated cartons are applied, in particular to a 02-type corrugated carton packing machine with duck tongue. Background technique [0002] The box structure division of corrugated boxes mostly adopts the international carton standard jointly designated by the European Corrugated Box Industry Association (FEFCO) and the Swiss Cardboard Association (ASSCO). Type 02 corrugated boxes are divided into corrugated boxes with duck tongues (attached figure 1 ) and corrugated boxes without duck tongues. Due to the structural limitations of corrugated boxes (with a hollow design in the middle), the forming method of corrugated boxes is very different from that of raw pulp paper boxes. This is because once the corrugated boxes have creases, It cannot be elastically recovered, and the original pulp paper has strong resilience properties because there is no hollow in the middle, and it is easy to recover eve...

AI Technical Summary

Problems solved by technology

[0003] In order to realize the automatic packaging forming of corrugated boxes, those skilled in the art are committed to the research and development of automatic packaging machinery, such as Chinese patent CN 105730772 A, which discloses an automatic corrugated box packaging machine, but this technology has the following defects: although it can The duck tongue can be inserted into the box body, but the structure is extremely complicated, and it needs to be driven by multiple cylinders, and only the pressure plate at the power end of the cylinder is used for mechanical extrusion. Restoration of creases; 2. The structure is too complex, which increases the difficulty of later maintenance, and the multi-stage transmission method increases the consumption of production time and reduces the packaging efficiency
