6-inch open mixing machine | Open rubber mixing machine factory direct sales

The abbreviation of open rubber mixing machine. A rubber mixing machine with exposed rollers used in rubber factories to prepare plasticized rubber, mixed rubber, or for hot mixing and extrusion. The main working parts are two hollow rollers or drilled rollers that rotate inward in opposite directions. The one installed on the operator's side is called the front roller. It can be moved forward and backward horizontally by manual or electric action to adjust the roller distance to meet the operating requirements. The roller is fixed and cannot move forward or backward. The two rollers are generally the same size and rotate relative to each other at different speeds. The raw rubber or rubber material is drawn into the gap between the two rollers as the rollers rotate, and is subjected to strong shearing to achieve the purpose of plasticizing or mixing. Open mills are also used in plastic processing and other sectors.
Open mill is the abbreviation of open plastic refining machine. In plastic products factories, people are accustomed to calling it two-roller machine. The open mill is a relatively early type of plastic mixing equipment used in plastic product manufacturers. In the calender production line, the open mill is in front of the calender and after the mixer. Its function is to mix and plasticize the uniformly mixed raw materials, and provide a relatively uniform molten material for the calender to roll and mold the plastic products. When producing cable materials, the open mill can directly refining the powdered materials mixed according to the formula into molten materials, and then press-molding them into sheet-like ribbons, which can then be cut into granular shapes by the pelletizer. In the floor leather production line, the base coating can be directly mixed and plasticized evenly for cloth-based leather. The recycled waste plastic films (sheets) can also be re-refined in an open mill.
The open mill has a simple structure, is relatively easy to manufacture, is easy to operate, and is easy to maintain and disassemble. Therefore, it is widely used in plastic products companies. The disadvantage is that workers consume a lot of physical strength to operate. In a higher temperature environment, they need to mix and turn the materials by hand. The number of times the plastic sheets are manually turned over has a greater impact on the quality of the raw material.
Safe operation of open mill
The open mill is one of the main equipment in the rubber factory. The rubber mixing operation of the open mill is an accident-prone process, including personal accidents and equipment accidents.
In recent years, on the one hand, due to the rapid increase of rubber enterprises, especially the establishment of a large number of rubber enterprises in rural towns and villages, a large number of young workers without strict training have taken up rubber mixing jobs, and violations of safe operations are common. On the other hand, due to the continuous strengthening of the production capacity of the rubber mixing machine, and because some steel wire radial tires and wide-section tires require an increase in the hardness of the tread rubber, the lateral pressure of the rubber mixing machine increases, resulting in frequent damage to the safety sheet and rollers. A barrel rupture accident occurred. Therefore, the safety status of rubber mixing operations is not optimistic
Protecting the safety and health of workers in production is an important policy of our country. Protecting national property and promoting production development are important responsibilities of enterprise management. Therefore, as far as rubber companies are concerned, they should pay attention to the safety of start-up operations. : Make preparations
