Improved device of U shaped cutter pair press roll of cellophane paper cigarette packer

Abstract

The invention discloses an improved device of a U-shaped cutter of a transparent paper packing machine on a roller, which comprises a pair roller support (7), a bracket (8), a conveying platform soleplate (1) in the pair roller support (7), a pair roller (2), a shaft (3), a U-shaped cutter (4) and a pressure spring (5). Wherein, the pair roller support (7) is provided with a bearing (6); the pressure spring (5) is connected with the U-shaped cutter (4) and is positioned on the upper end of the bearing (6); the bracket (8) is the installation bracket of the bearing (6); the bearing (6) is fixed on the support (7) via pin rolls and is fixed on the support (7) and the conveying platform soleplate (1) via bolts; bolts for installing the bracket (8) are designed six. The price of adopting the device is lower than that of the pair roller, the service lives of the bearing and the U-shaped cutter are prolonged, the maintenance is convenient and the invention is suitable for the production of various trademarks.

Description

technical field [0001] The invention relates to a component of a strip outer transparent paper packaging machine, in particular to an improved device for a U-shaped cutting knife opposing a pressure roller of a transparent paper packaging machine. Background technique [0002] The transparent paper supply of YB95 type transparent paper packaging machine is completed by the unfolding and cutting device of the transparent paper. First, it is cut into pieces of cellophane by a cutter, and finally packed outside the tobacco rod by the transparent paper packaging machine. In order to tear off the transparent paper outside the box, the transparent paper packaging machine is designed with a U-shaped U-shaped cutter and a counter-pressing roller. Its function is to cut a U-shaped tear on the transparent paper. However, in the production process, problems such as incomplete transportation of transparent paper and skewed transportation often occur due to incomplete cutting of the U-sh...

AI Technical Summary

Problems solved by technology

However, in the production process, problems such as incomplete transportation of transparent paper and skewed transportation often occur due to incomplete U-shaped tear cutting.

At the same time, during the adjustment process, we often find that one side of the U-shaped knife edge on the transparent paper is cut intact, and one side is cut with burrs. It is also difficult and time-consuming

Since the hardness of the pressure roller is much lower than that of the U-shaped cutter, after a period of operation, the pressure roller will be squeezed and engraved with a pit that is roughly the same shape as the U-shaped cutter. The wear is irregular, so the pit of the U-shaped cutter is uneven. When the unevenness reaches a certain level, the U-shaped incision of the transparent paper cannot be completely cut.

It is precisely because the two transparent papers are intertwined with each other that the cut transparent paper has an extra traction force during the conveying process and loses its original balance. Failures such as inappropriate conveying of the transparent paper and skewed conveying will inevitably occur.
