The invention discloses a drive method of a pneumatic-hydraulic united controlled upper ram weight of a Banbury mixer. The drive method is characterized in that: a hydraulic control device is adopted for drive control of a lower weight and a lifting weight of a weight (7), and a pneumatic control device is adopted for drive control of floating and a floating weight of the weight (7). A drive unitfor realizing the method comprises 2 upper ram oil cylinders (13) arranged above the Banbury mixer (8) and the hydraulic control device of the upper ram oil cylinders (13), piston rods (12) of the upper ram oil cylinders (13) are connected by a cross beam (11), and the drive unit is characterized in that: the cross beam (11) is provided with a single-acting cylinder (9) and the pneumatic control device of the single-acting cylinder (9), a piston (5) of the single-acting cylinder (9) is connected with the weight (7) by a connecting rod (10). The drive method is practical and the drive unit is simple and easily controlled, and the method and the unit have the advantages of greatly simplifying a control system to be simple and reliable, and greatly reducing manufacturing and maintenance cost.
Description
Technical field: [0001] The invention relates to an internal mixer, in particular to the control of the top bolt weight on the internal mixer, in particular to a driving method and a driving device for the top bolt weight on the internal mixer. Background technique: [0002] The internal mixer is the key equipment for processing rubber raw materials into semi-finished rubber in the rubber industry. The top bolt is the core part of the internal mixer. The tracking motion is generated by the change of volume, including working conditions such as lowering, lifting, floating and floating. At present, there are two types of control of the jacking weight on the internal mixer: pneumatic control and hydraulic control. Although the pneumatic control method has the advantages of simple and reliable control of floating and floating weights, no need for servo, and no need for commutation in tracking motion. However, there are problems such as slow lifting and lowering speed and low w...
