Environmentally-friendly three-cylinder dryers are currently known as the most common and widely-used dryer equipment in the drying industry. Its production characteristics are high production efficiency and convenient operation. The cylinder of the environmental protection three-cylinder dryer is a horizontal rotary cylinder. The inside of the cylinder is welded from front to back with various types of copying plates with different arrangement angles. Inlaid with different types of firebrick, in the feed end to prevent pouring with a door ring and spiral copy board. The new type of equipment is fully equipped with the advantages of reasonable structure, superior production, high output, low energy consumption, and easy operation.
The environmental protection three-cylinder dryer has strong anti-overload capability, large processing capacity, low fuel consumption, and low drying cost. The environment-friendly three-cylinder dryer adopts the co-current drying method. Hot air and wet materials enter the dryer from the same side. High-temperature air can be used to obtain high evaporation intensity, the outlet temperature of the dryer is low, and the thermal efficiency is high. The dryer can change the operating parameters according to different material properties, so that the material can form a stable full material curtain in the cylinder of the drying equipment, and the quality heat exchange is more fully. The dryer adopts a new type of feeding and discharging device, which eliminates the clogging, discontinuity, non-uniformity, and material return of the previous dryer, and reduces the load on the dust removal system. The environmental protection three-cylinder dryer achieves 'zero-level thrust', which greatly reduces the wear of the brace wheel and ensures smooth and reliable operation of the cylinder. The dryer adopts a 'centering roller support device' to ensure that the support roller and the roller ring are always in linear contact, thus greatly reducing wear and power loss, and controlling the moisture content of the product according to user requirements.
The environment-friendly three-cylinder dryer only stabilizes the production quality of the equipment and strengthens the production performance of the equipment. According to effective production experience, the internal structure of the equipment is constantly improved, and the equipment is effectively repaired and maintained in order to make the environment-friendly three-cylinder dryer. The use of production farther away, the development of environmentally friendly three-cylinder dryer high-quality production determines the direction of development of the equipment in the market. In response to the development needs of the market, as a high-tech environmental protection three-cylinder dryer technology company, whether it is from technology or quality, we Jinhua Machinery are doing their best to continuously improve, so that our new environmentally friendly three-cylinder drying Dry machine equipment gradually tends to be internationalized. Creating more successful market areas leads us to the right and successful direction of development.
Hot Runner System
Hot runner systems are feed systems for injection molds which convey molten plastic from the machine nozzle into the cavity. Hot runner systems consist of the components listed below, from which your individual system can be made.
Although there are many hot runner manufacturers and multiple hot runner product series in the world, a typical hot runner system is composed of the following parts:
1. (MANIFOLD)
2. (NOZZLE)
3. Temperature Controller
4. Auxiliary parts
The types and applications of these parts will be discussed in depth in future articles.
Technical key
A successful hot runner mold application project needs to be guaranteed by multiple links. Two of the most important are technical factors. One is the control of plastic temperature, and the other is the control of plastic flow.
1. Plastic temperature control
Plastic temperature control is extremely important in hot runner mold applications. Processing and product quality that appear in many production processes
The problem directly stems from the poor temperature control of the hot runner system. Such as the problem of poor quality of the gate of the product during injection molding using the hot pin gate method, the difficulty of closing the valve pin during the molding of the valve gate method, the problem of inconsistent filling time and quality of parts in the multi-cavity mold. If possible, you should try to choose a hot runner system with separate temperature control in multiple areas to increase flexibility and adaptability.
2. Control of plastic flow
Plastics must flow balanced in the hot runner system. The gate should be opened at the same time to allow the plastic to simultaneously fill each cavity. For FAMILY MOLD, where the weight of the parts differ greatly, the design of the runner size should be balanced. Otherwise, there will be problems that some parts are not filled enough, but some parts are overfilled, and the flash is too large and poor quality. The size design of hot runner runner should be reasonable. The size is too small and the pressure loss of the mold is too large. If the size is too large, the volume of the hot runner is too large, and the residence time of the plastic in the hot runner system is too long, which may damage the performance of the material and cause the parts to fail to meet the requirements after molding. There are already CAE software such as MOLDCAE in the world that specifically help users to design the best runners.
