Electric Cylinder With Ball Screw
*Internally equipped with a pair of high-strength tapered roller bearings that meet both thrust and tension conditions;
*Good lubrication characteristics, operating environment temperature.
*High quality hydraulic oil seals are used at both ends of the cylinder block, with excellent sealing performance;
*Equipped with two travel limit sensors.
Due to the high transmission efficiency and lack of self-locking characteristics of the ball screw inside the electric cylinder, when the expansion rod nut moves in a straight line inside the electric cylinder barrel, the expansion rod nut will rotate slightly in the direction of the ball screw thread due to inertia and friction. When the internal anti rotation limit of the electric cylinder or the end of the telescopic rod is connected to a non rotating structural component using a U-shaped double ear seat (or thread), the rotational movement of the telescopic rod is restricted, and the electric cylinder telescopic rod can be retracted without rotation. The general application requires anti-rotation restrictions on the piston rod. In some cases, such as front and rear U-shaped fork foot electric cylinders, six degree of freedom platforms, etc., electric cylinders without anti rotation structures are required. The rotation of the telescopic rod will affect the displacement accuracy of the electric cylinder, and it should generally be determined in the early stage of selection whether the electric cylinder requires anti rotation.

The two-stage pelletizing system applied in the re-pelletizing job, which consists of two sets of single screw extruder, in case that recycles are with heavy required higher pelletizing output. The ACSS series compacting and pelletizing system combines function of crushing, compacting, plasticization and pelletizing to one step. ACSS system is a reliable and efficiency solution for plastics films, raffias, filaments, bags, woven bags and foaming materials re-pelletizing.
Final productions produced by ACSS system are in the form of pellets/ granules, can directly put into the production line for film blowing, pipe extrusion and plastics injection, etc.

Working steps of ACSS compacting and pelletizing system
1. Feeding: as standard design, plastic scraps such as film, filament, raffias conveyed into the compacting room through belt conveyor; to handle rolls' scraps, roll hauling off device is an optional feeding method. Motor drives of conveyor belt and hauling device cooperate with ABB inverter. Feeding speed of conveyor belt or roll hauling off is fully automatic based on how full the compactor's room is. Metal detector can be combined with belt conveyor, and can interlock with control system, to warn and stop the system, in case that metal is found in feeding section.
2. Crushing and compacting: the rotatory blades of compactor will cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrinking just below their agglomerating point. Optimal designed guide structure compacts the material and directs it into extruder screw. Crushes, dries and compacts the material which enables a fast and stable feeding from the compactor directly into the extruder.
3. Plasticization and degassing: A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in the first stage extruder, and the plastic will be extrude by the second stage extruder. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with some water content.
4. Melt filtration: Segmented filtering principle, fore filtering in the first extruder, and fine filtering in the second extruder, to reduce the frequency of filtering sieves changing. The requirements on the filter technology depend heavily on the quality of the input material as well as the planned use of granules.
5. Pelletizing: die-face water ring pelletizing system set as the standard granulating method in ACSS system. Self-adjusting pelletizing head for the best granulate quality and long uptime thanks to consistently correct blades pressure. RPM of rotatory blades is automatic based on melt extruding pressure. Advanced dewatering vibration sieve combining with horizontal-type centrifugal dewatering present high performance dried pellets.
