Tubular corrugated paper sleeve forming machine with elastic glue injection box bottom board

Abstract

The invention discloses a tubular corrugated paper sleeve forming machine with an elastic glue injection box bottom board. The forming machine comprises a rack, a feeding mechanism, an edge gluing mechanism and a rounding edge drying mechanism. The feeding mechanism comprises a feeding rail board and a feeding rail board sliding drive air cylinder. The edge gluing mechanism is arranged on a gluing base board above the feeding rail board. The rounding edge drying mechanism comprises a support board, a rounding core die, a rounding locating press board, an edge clamping top board and two rounding force applying assemblies arranged on the left side and the right side of a rounding die. A feeding hole is formed in the support board and connected to the discharging end of the feeding mechanism. A hot air cavity is formed in the edge clamping top board. Multiple hot air holes communicated with the hot air cavity are formed in a top board body of the edge clamping top board. The support board is further provided with a hot air blower connected with the hot air cavity through a pipeline. The tubular corrugated paper sleeve forming machine has the advantages of being reasonable in structural design, high in machining efficiency and good in forming consistency of products.

Description

technical field [0001] The invention relates to a molding machine, in particular to a tubular corrugated paper sleeve molding machine with an elastic rubber injection box bottom plate. Background technique [0002] After the existing milk tea cup is made tea, in order to prevent the hands of the drinker from being scalded by the milk tea, it is necessary to be provided with a tubular corrugated paper cover on the milk tea cup overcoat to facilitate heat insulation. In addition, with the advancement of technology, the requirement for tubular corrugated paper sleeves in the market is to open holes on the top so that the liquid level of the milk tea cup inside the tubular corrugated paper sleeve can be observed in real time. [0003] However, in the prior art, the molding process of the tubular corrugated paper sleeve is generally carried out manually, and the method is as follows: generally by gluing, rounding and drying the edge glue parts of the cut corrugated paper sheet. ...

AI Technical Summary

Problems solved by technology

Since this molding method is all done manually, the processing efficiency is low, the labor intensity is high, and the product processing consistency is poor, so it is necessary to improve

[0004] In addition, in the prior art, the corrugated paper sheets used for forming tubular corrugated paper sleeves are generally cut by hand, and the cutting size consistency is poor.
