What is the working principle of the bubble film machine?
The bubble film machine is a mechanical equipment designed for the manufacture of bubble film. The bubble film it produces has the advantages of light weight, shockproof, moisture-proof and good protection effect. Therefore, it has been widely used in many fields such as packaging, logistics and electronic products. With the continuous enhancement of people's awareness of environmental protection, more and more people have begun to pay attention to the quality of bubble film. Therefore, it is of great significance to study the bubble film machine. A deep understanding of the operating mechanism of the bubble film machine can help us operate and maintain this equipment more efficiently, thereby improving its manufacturing efficiency and product quality.
What mechanism is used to achieve the bubble generation of the bubble film machine?
The mechanism of bubble generation by the bubble film machine depends on a specific mechanical structure. In the bubble film machine, the melt enters the mold cavity from the feed port through the extruder for cooling and solidification. The bubble film machine is equipped with a set of specially designed molds. When the molten raw materials pass through these molds, due to the unique design of the internal structure of the mold, continuous and uniform bubbles can be generated during the extrusion process. After this gas is ejected from the nozzle, after a series of complex movements and force analysis, a large number of tiny, dense bubbles will be generated. These bubbles form a specific shape inside the mold, and continue to move forward with the extrusion of the raw materials, and finally build a complete bubble film.
How are the raw materials heated and extruded during the production process of the bubble film machine?
The materials used in the bubble film machine are mostly made of plastic particles such as polyethylene. These materials generally have a high melting point and low fluidity, and are prone to aging or cracking. In the manufacturing process, this batch of raw materials will first undergo a series of pretreatment steps, including mixing and drying, to ensure their quality and stability. In order to ensure that the raw materials can enter the bubble film machine smoothly, they must be preformed. Then, the raw materials are transported to the heating system of the bubble film machine for heating and melting. The heated material enters the extruder, contacts with the air and generates heat, thereby melting it into a melt. During the heating process, the raw materials are heated to a specific temperature, so that they enter a molten state. When the molten raw materials are discharged from the cooling chamber, the extrusion force generated by the expansion of the gas squeezes the raw materials into the molding cavity. Subsequently, the molten raw materials are transported to the extrusion die, and a continuous bubble film is generated under the extrusion of the die. In this process, core parameters such as heating temperature, extrusion rate and pressure play a decisive role in the quality of the final product.
How does the bubble film machine adjust the size and density of bubbles through the control system?
The control system of the bubble film machine is one of its key components, responsible for adjusting important parameters such as the size and density of the bubbles. Most of the bubble machine systems currently sold on the market adopt a mechanical structure and cannot meet modern production requirements. Usually, the control system is composed of a PLC (programmable logic controller) and other electronic components. It can accurately adjust and control key parameters such as the amount of extrusion, the speed of bubble formation and the speed of traction by receiving feedback signals from sensors. In actual applications, due to different process conditions, the system may make corresponding adjustments according to production conditions. For example, when it is necessary to expand the size of the bubble, the control system can achieve this by increasing the amount of extrusion or reducing the speed of traction; when it is necessary to increase the density of the bubble, a feasible method is to speed up the generation rate of the bubble or reduce the amount of extrusion. Bubble film is a new functional material with excellent thermal insulation properties, which can be used to make thermal insulation products and thermal insulation materials. The performance of bubble film will be affected by the size and density of bubbles, such as its shockproof performance and protection function.
How do the traction and cutting devices of bubble film machines work to ensure the accurate length and width of bubble film?
The traction part of the bubble film machine mainly includes key components such as motor, reducer and transmission shaft. Its core function is to effectively traction and transmission of extruded bubble film. Among them, the motor, as the power source of the traction device, has a decisive influence on the quality of the bubble film. During the traction operation, the traction device ensures the continuity and stability of the bubble film, thereby ensuring the accuracy of its length and width. One of the most important processes in the production of bubble film is traction. The main responsibility of the cutting device is to cut the continuous bubble film into a final product of a specific length. Therefore, there is a close relationship between the bubble film traction device and the cutting device. There are many types of cutting equipment, including but not limited to mechanical cutting and laser cutting. Among them, mechanical cutting is mainly used to produce products of different sizes, including plates of various shapes and sizes. In the mechanical cutting process, the bubble film is usually cut by tools such as blades or saw blades; laser cutting technology is a rapid and accurate cutting operation of the bubble film by laser beam. At present, the most commonly used cutting device in China is mechanical cutting. Regardless of which type of cutting equipment is used, they can ensure that the size of the bubble film meets the predetermined standards.
How does the bubble film machine achieve automatic roll change and continue production after completing the production of a roll of bubble film?
The automatic roll change function in the bubble film machine is one of the core components to ensure its continuous production. The automatic roll change device includes a roll film pick-up and place member for removing the roll film from the frame and a pneumatic control system that can move the roll film in the vertical direction and drive the roll film to move along the length direction of the roll film. Once the production of a roll of bubble film is completed, the automatic roll change device will be automatically activated. It will detect the position of the end of the roll film through a sensor and control the roll film switching mechanism accordingly to achieve automatic switching of the roll film. When the roll film runs to the end point, the roll film drive motor stops working, thereby pulling the roll film out of the production line. During the production switching process, the newly manufactured roll film is automatically guided to the production line and continues to produce bubble film. Therefore, the replaced bubble film needs to be monitored in real time. At the same time, in order to ensure the continuity and stability of the bubble film, the traction device will also be reactivated. This article introduces a fully automatic bubble film reel changing machine, which is mainly composed of three parts: control system, drive system and transmission system. The use of automatic reel changing equipment significantly enhances production efficiency, reduces dependence on labor, and reduces the total cost of manufacturing.
When we re-examine the operating mechanism and core components of the bubble film machine, we will find that the bubble film machine is a highly efficient, stable and very reliable mechanical device. Its core part is a complete system consisting of an air source system, a gas-liquid separation device and a control device. The equipment uses a specific mechanical structure to generate bubbles and perform continuous extrusion molding; through a precise control system, we can adjust the core parameters such as the size and density of the bubbles; use traction and cutting equipment to ensure that the length and width of the bubble film are accurate; and use automated reel changing equipment to achieve the purpose of continuous production. The bubble film has a simple and compact structure, which can effectively reduce energy consumption, improve product qualification rate, and reduce equipment investment costs and floor space.
