Description

Double-roller open mill for producing color chips

Technical Field

The utility model relates to the technical field of open mill equipment, in particular to a double-roller open mill for producing color chips.

Background

Open mill is short for open mill. The rubber factory is used for preparing plasticated rubber, mixed rubber or a rubber mixing machine with an exposed roller for hot mixing and discharging.

The main working components are two hollow rollers or drilling rollers which rotate in different directions inwards, one side of the device, called a front roller, of an operator can horizontally move back and forth through manual or electric operation so as to adjust the roller distance and adapt to the operation requirement; the rear roller is fixed and cannot move back and forth. The two rollers are generally the same in size and rotate relatively at different speeds, and raw rubber or rubber compound is rolled into the gap between the two rollers along with the rotation of the rollers and is subjected to strong shearing action to achieve the purpose of plastication or mixing. Open mills are also used in the sector of plastics processing and the like.

An open mill is a short name of an open plastic refining machine, and is also commonly called a two-roller machine in plastic product factories. An open mill is a plastic mixing device which is earlier applied by a plastic product production plant. On a calender production line, an open mill is arranged before a calender and behind a mixer and is used for mixing and plasticizing the uniformly mixed raw materials to provide a molten material which is uniformly mixed and plasticized for a plastic product which is calendered and molded by the calender. When producing the cable material, the open mill can directly smelt and mould the powdery material mixed according to the formula into molten material, and then the molten material is pressed and moulded into a flaky belt, so that the granulator is cut into particles. On a floor leather production line, the primer which is mixed and plasticized uniformly can be directly provided for the cloth-based leather. The recycled waste plastic film (sheet) can also be re-refined and recycled on the open mill.

The open mill has simple structure, easy manufacture, easy operation and convenient maintenance and disassembly, thereby being widely applied to plastic product enterprises. The disadvantages that the labor consumption of workers is large, the mixed materials need to be manually mixed and turned in a high-temperature environment, and the influence of the times of manually turning the mixed plastic sheets on the quality of the mixed materials is large.

In the production process of color chip, the mill is by extensive application, but current mill has a problem when using, when putting into the raw materials, because the size of raw materials is different, there is the influence to the mill process, can cause the influence to the product quality of production when subsequent mill, and efficiency also can be underneath, need filter it, and filterable effect and inefficiency are not conform to the demand in market to current mill when throwing the material.
