Intelligent plastic film bag making device

Abstract

The invention relates to an intelligent plastic film bag making device which consists of a film feeding part and a bag making part. After a controller gives an instruction of making a bag, the film feeding pat performs treatments such as proper folding and flattening on a plastic film and then sends the plastic film to the bag making part; a coder of the bag making part can control the width of the bag to be made; when the film is sent in place, a film cutting blade of the bag making part perform cutting and hot sealing on the film so as to obtain a plastic film bag; and finally a finished product is taken away by a bag transferring part of the bag making part. The device provided by the invention adopts simple mechanical forms to make the film bags with different dimensions, so that requirements for making packing bags with different dimensions can be met. Execution components of the device are a motor and a cylinder, which can easily realize high-precision control and fast production; a sensor is adopted to monitor work situations of key parts in real time, so as to realize intelligentization in making the bag. The device provided by the invention improves the stability of product dimension and the quality of packing bag sealing, promotes the productive efficiency and saves the labor cost.

Description

technical field [0001] The invention relates to an intelligent plastic film bag forming device, which belongs to the application field of packaging machinery. Background technique [0002] With the diversification and high-grade of product categories, people put forward higher and higher requirements for the packaging quality of products. The outer packaging commonly used by current products is mostly plastic products, among which plastic bags are particularly common. In the current bag making technology, there is no automatic deviation correction device in the film feeding stage, and it can only be adjusted manually, which is inefficient and imprecise. At the same time, the existing bag forming device cannot automatically and intelligently adjust the size of the bag, which seriously restricts the application field of the device.

At the same time, the existing bag forming device cannot automatically and intelligently adjust the size of the bag, which seriously restricts the application field of the device

[0003] The bag forming method of plastic bags is mostly heat sealing method. This bag forming method is simple and low in cost, but this method also has many shortcomings. Since the blade heating is mostly electric heating, the stability of the voltage has a great impact on the bag forming method. The quality of the bag has a great influence. To obtain high-quality bag products, it is necessary to use a professional power supply, which will increase the cost. At the same time, this method has high requirements for the material of the blade, which requires good thermal conductivity, fast heating, and low viscosity. The performance is stable, so general metal materials are difficult to meet the requirements. In addition, the temperature of the working environment has a great influence on the temperature of the blade. The temperature of use in different seasons and regions is different, which adds limitations to this bagging method and has many shortcomings. It affects the quality and efficiency of bag making, and increases the cost of bag making. Therefore, how to manufacture an intelligent heat-cutting and sealing bag-making device not only has a simple mechanism, but also can meet the requirements of different environments and regions. At the same time, it can self-adjust the temperature of the blade to ensure the stability of the temperature at all times to improve the quality of the bag. At the same time, it can be automated to improve production efficiency is the current research focus in the packaging field.
