一种薄膜标签切断装置

Abstract

本实用新型公开了一种薄膜标签切断装置，属于包装用商标标签处理技术领域。本实用新型包括并列固定连接于安装平台上的刃具组件和刀鼓组件；刃具组件包括刃具、轴座和连接于轴座内的刃具轴，以及嵌接于刃具轴轴面的夹具固定座和向外开设于夹具固定座中的基准槽；刃具通过气囊夹具可拆卸固定于基准槽内；刀鼓组件包括刀鼓轴以及套接固定于刀鼓轴轴身的刀鼓环，刀鼓环的周面嵌接有垫刀块；刃具轴和刀鼓轴转动过程中，完成薄膜标签的切断动作；再通过刃具轴和刀鼓轴的顶端均与各自适配电机的输出轴传动连接；解决了现有技术中刃具夹紧结构较大，刃具本身又很小，造成安装维修不便捷以及刃具轴与垫刀鼓轴同一个电机驱动，无法改变传动比的问题。

Claims

1. A film label cutting apparatus characterized by comprising: Includes a cutting tool assembly and a blade drum assembly that are fixedly connected in parallel to the mounting platform; wherein: The cutting tool assembly includes a cutting tool, a bearing seat, and a cutting tool shaft connected within the bearing seat, as well as a clamping base fitted into the shaft surface of the cutting tool shaft and a reference groove extending outward from the clamping base; the cutting tool is detachably fixed in the reference groove by an airbag clamp. The blade drum assembly includes a blade drum shaft and a blade drum ring that is sleeved and fixed to the shaft body of the blade drum shaft. A pad block is embedded in the circumferential surface of the blade drum ring. During the rotation of the blade shaft and the blade drum shaft, the cutting action of the film label is completed when the blade and the pad block are tangent.

2. The film label cutting device according to claim 1, characterized in that: A pressure plate is also provided between the cutting tool and the airbag clamp; The blade drum ring consists of two split blade drum halves, both of which are fixedly connected to the blade drum shaft body by screws; the end face of the blade drum halves is provided with a mounting groove adapted to the shape of the blade pad block, and the blade pad block consists of two symmetrical pieces, which are pressed against the corresponding end faces of the two blade drum halves.

3. The film label cutting device according to claim 2, characterized in that: A pad is also provided between the cutting tool and the reference groove wall; The top ends of the cutting tool shaft and the blade drum shaft are both connected to the output shaft of their respective compatible motors. The blade drum semi-ring has interconnected axial vacuum holes and radial vacuum holes, with a vacuum tube connected to the outside of the axial vacuum hole; the radial vacuum holes on the surface of the blade drum semi-ring form a vacuum adsorption surface for the thin film label.

4. The film label cutting apparatus of claim 1, wherein: The blade shaft has an axial main vent hole in the middle, which is connected to the airbag clamp through a vent hole. Compressed air is connected to the main vent hole.

5. A film label cutting apparatus according to any one of claims 2 to 4, wherein: The clamp fixing base consists of two symmetrically arranged sets, which are adapted to the corresponding two pad blocks.

6. The film label cutting apparatus of claim 5, wherein: The airbag clamp includes a clamp seat embedded in the wall of the reference groove. An airbag groove is formed on the end face of the clamp seat near the cutting tool. An airbag is placed inside the airbag groove. A clamping plate is slidably connected to the wall of the airbag groove outside the airbag.

7. The film label cutting apparatus of claim 3, wherein: The vacuum source required for the vacuum adsorption surface is supplied sequentially to the vacuum buffer chamber and the blade drum assembly via a vacuum tube at the bottom of the installation platform through a static sealing assembly.

8. The film label cutting apparatus of claim 7, wherein: The static sealing assembly includes a vacuum chamber support, a pressure spring, upper and lower floating discs, and a vacuum buffer chamber; the upper and lower ends of the vacuum chamber support are connected to the vacuum buffer chamber and the vacuum tube, respectively; the upper and lower floating discs are pressed against the top of the blade drum ring by the pressure spring; the axial vacuum hole is connected to the vacuum buffer chamber.
