Systems, devices, and methods are disclosed for a rosin press that allows improved extraction over existing presses. The press includes improved platens for rosin collection with built-in gutter rail collection systems and well-distributed force on the pressed product and multiple hydraulic rams. In addition, computerized systems are provided for controlling and monitoring the system in an automated fashion, as well as safety features to prevent injury and damage to the product, especially during automated pressing.

An apparatus for the controlled return of the stems in cylinders of the types that can be applied to a press for stamping sheet metal, comprising: at least one fluid-operated cylinder), at least one hydraulic accumulator which is fluidically connected to the at least one cylinder by means of a hydraulic circuit which comprises: a duct for the discharge of the working fluid from the at least one cylinder and a duct/branch for the intake of the working fluid in the hydraulic accumulator, a duct for loading the working fluid in the at least one cylinder and at duct/branch for the output of the working fluid from the hydraulic accumulator.

Systems, devices, and methods are disclosed for a rosin press that allows improved extraction over existing presses. Computerized systems are provided for controlling and monitoring the system in an automated fashion, including via a wireless device or a server.

A material handling apparatus is described comprising a material press body having an inlet and an outlet; a power source for generating an airstream into the inlet of the material press body and through the outlet of the material press body, wherein the airstream captures and feeds a supply material into the material press body; a plurality of press augers for capturing and manipulating the supply material into the material handling apparatus; and a drive system connected to drive and control the plurality of augers.

A portable roller compactor for compacting waste located in a container, which is open on the top, has a frame-like basic structure and an articulated arm, one end of which is supported by the basic structure, and the other, free end of which supports a roller compactor that essentially can be rotated about a horizontal axis of rotation. The articulated arm of the roller compactor is pivotably attached to a sliding carriage, which is mounted on the frame-like base structure and can be moved in a longitudinal direction.

A pneumatic chamber 20 is configured to include a first pneumatic chamber 21 pressurizing a first piston 11 and a second pneumatic chamber 22 pressurizing a second piston 12. The first pneumatic chamber 21 communicates with the second pneumatic chamber 22. The hydraulic pressure generating unit 55 is internally provided with a hydraulic chamber 30, and the hydraulic chamber 30 is configured to have a first hydraulic chamber 31 pressurized by the first pneumatic chamber 21 via the first piston 11 and a second hydraulic chamber 32 pressurized by the second pneumatic chamber 22 via the second piston 12. The hydraulic pressure generating unit 55 is movable in a thrust direction in a cylinder 2, and the second hydraulic chamber 32 has a function of fixing the moving hydraulic pressure generating unit 55 in the cylinder 2 by causing a thin portion 15 to be elastically deformed in a radial direction due to hydraulic pressure. The first hydraulic chamber 31 outputs hydraulic pressure of the first hydraulic chamber 31, which is increased by the fixing, to an output rod 7.
