What are the main types of blow molding machine screws?

The screw of the blow molding machine is an important component of the blow molding machine. What are the main types of blow molding machine screws? The main types of blow molding machine screws are ordinary type, separation type, and mixing type, and their structures and characteristics are as follows: Blow molding machine screw model one: ordinary screw The ordinary screw can be divided into three sections in structure, namely the feeding section, the transition section, and the metering section. The three segments are independent of each other and do not overlap, characterized by a length to diameter ratio (L/D) of (20-30)/1; The length of the feeding section is (4-8) D, and the length of the measuring section is (6-10) D. Its function is to carry out solid conveying, melting, melt conveying, exhaust and mixing of raw materials. Blow molding machine screw model two: separation type screw The separated screw structure is generally the same as the ordinary screw structure, but the difference is that the separation section is used instead of the gradient section. The length of the separation section is 5-15 times the diameter of the screw. In the separation section, there is a barrier edge (also known as a secondary edge) inside the screw groove, and the gap between this secondary edge and the wall of the machine barrel is greater than the gap between the main edge. When designing, it is advisable to ensure that the melt can smoothly pass through the secondary helix while preventing large-sized solid particles from crossing the secondary helix. The use of this spiral edge can effectively separate the plastic melt from the solid, forming two adjacent spiral grooves. The cross-section of the plastic solid groove gradually decreases along the direction of the spiral groove, while the cross-section of the melt groove gradually increases, reaching the end of the separation section. The solid groove disappears, and the melt groove occupies the entire spiral groove. Its function is to separate the plastic solid from the melt, which is beneficial for stabilizing the solid bed and reducing or eliminating the degree of damage to the solid bed; And it can make the plastic melt completely or mostly pass through the secondary groove edges. This makes the plastic melt more uniformly and strongly sheared, resulting in better rheological properties of the plastic melt. Blow molding machine screw model three: mixed screw The mixing process of mixed screw plastics can be divided into distributed mixing and dispersed mixing. Distributed mixing refers to mixing in which the fluid does not exhibit yield stress, but only increases the spatial distribution between components, and the size of the components does not change. Dispersive mixing is a mixing process that can make the melt present yield stress, which can make the material mass or gel be crushed to a critical size and distributed into the mixture. In the process of plastic processing, dispersed mixing is always accompanied by distributed mixing, but distributed mixing is almost never accompanied by dispersed mixing.

Staff should pay attention to checking the following six points in their daily work

Staff should pay attention to checking the following six points in their daily work

1.Before starting the plastic hollow blow molding machine, it is necessary to add lubricating oil to each moving component once. Check if each moving component is sturdy,Are there any loose or scattered screws, especially in the center with strong impact force, and can the belt transmission be normal in some parts. 2.Plastic hollow blow molding machine molds require regular cleaning and polishing. 3.The staff needs to check if the lamp tube is damaged or broken. It needs to be replaced in a timely manner. Check if there is any air leakage in each pneumatic component and if the action is flexible. Check for any abnormal air leakage in the triad,When the electromagnetic valve of the plastic hollow film blowing machine encounters abnormalities, it should be cleaned in a timely manner. 4.Arm swing can be added once every three to four days. The large and small chains of the heating machine can be used once a month. Regularly check if the main engine reducer and heater reducer are out of oil. The main engine bearings can be added once every two to three months. 5.Check if the high-pressure gas source, low-pressure gas source, power supply, and water source are functioning properly. Check if all emergency stop switches, safety door switches, and maintenance installation inspection switches are functioning properly. 6.Check if the heating head enters the embryo and if the dropped part works properly. If the insertion is not in place, adjust the pressure and install the nut.The above six points are detailed components for inspection. The service life of the machine depends not only on the quality of the machinery itself, but also on the skills and techniques of the workers.

What is the main source of power for blow molding machines?

A blow molding machine is a machine that blows heated and plasticized thermoplastic rolls such as PVC, PE, PP, PET, HIPS, etc. into various shapes of high-end packaging and decoration boxes, frames, and other products. The operation steps are also very simple. It only needs to turn on the heating switch and connect the heating time switch circuit, adjust the heating time switch to set the time button, and select the appropriate heating time for the electric heating element of the electric wood mold according to the actual packaging situation. Blow molding machine principle: Blow molding, also known as thermoplastic molding, is a molding process that mainly uses the vacuum blowing force generated by a vacuum pump to heat and soften thermoplastic sheets such as PVC, PET, PETG, APTT, PP, PE, PS, etc., and then blow molded into various shapes of vacuum covers, blow molding trays, bubble shells, etc. through molds. Its main structure is composed of feeding, pulling, upper and lower electric heating furnaces, lower gate, multifunctional adjustable size, lower mold plate, upper mold, upper gate, knife gate, slicing, chip placement, and vacuum device, etc; Using pneumatic devices as the main power source, the automatic control system is composed of electric pulling and feeding devices, speed reducers, time relays, intermediate relays, travel switches, and other electrical appliances The requirements for the control system of blow molding machines are to ensure easy operation, high precision in mechanical action and temperature control, short production time, and to save mechanical power consumption as much as possible under the same production conditions.

Blow molding machine manufacturers constantly innovate and seek development

Against the backdrop of changes in market demand layout and macroeconomic environment, blow molding machine manufacturers are constantly innovating and entering a new stage of development, producing products that are more suitable for market demand. At present, the popular packaging in the market is mainly made of plastic and paper. The blow molding industry, which is mainly based on plastic film blowing machines, has a relatively large proportion in the market. However, with the increasingly strict requirements for the paper making industry, the new index of environmental protection and energy conservation has advanced the threshold for the paper making industry, forming a cost expansion and price decline in the paper packaging market. This has led to an increase in the market share of plastic packaging, stimulating the development of the blown film machine production machinery industry. At the same time, environmental protection and energy-saving techniques have been given attention in the blown film machine industry. With the increasing popularity of green and energy-saving concepts, many high consumption, low efficiency and other mechanical products in the market are gradually being phased out. Manufacturers are keeping up with the trend and moving towards energy conservation and emission reduction. The plastic film blowing machine manufacturing industry applies high-tech, and the new type of film blowing machine produced meets the diversified needs of the market. In order to meet the needs of social products and environmental protection, blow molding machines will continue to introduce the ingenious skills of younger generations, mediate the current mode, and promote the plastic industry to move towards the high-end. The new film blowers produced by modified plastic manufacturers include sheet film blowers, PE foam film blowers, multi-layer composite film blowing modified plastic machines, color stripe film blowers, heat shrinkable short film blowers, etc., which meet the packaging requirements of various products in the market. The high-end film blowing quality has won the favor of high-end commodity packaging. What is the main source of power for blow molding machines?
