Rotary Suction Head Mechanism

CN115636253A / CN115636253B · Invention Patent · Granted May 9, 2025

This patented rotary suction head mechanism comprises a frame, rotary seat, multiple support arms, material-gripping suction cups, a driving device and a coordinated linkage system.

As the rotary seat turns, the linkage mechanism controls the movement of the support arms so that the suction cups remain oriented outward. The design is intended to improve the controlled pickup, rotation and placement of paperboard during the wrapping process.

  • Application publication: CN115636253A
  • Granted patent: CN115636253B
  • Application number: CN202211385033.3A
  • Patent type: Invention patent

Swing-Arm Self-Locking Safety Mechanism for a Wrapping Machine

CN116142560B · Invention Patent · Granted July 25, 2025

This patented safety mechanism is designed for the movable swing arm of a wrapping machine. It incorporates a locking groove, spring-loaded locking unit and locking component that automatically secures the swing arm when it is raised.

To lower the swing arm, the operator presses the locking component to disengage it from the inclined locking surface. The patent also describes a buffering structure positioned beneath the swing arm to support safer and more controlled movement.

  • Patent number: CN116142560B
  • Application number: CN202211387939.9A
  • Patent type: Invention patent

Synchronous Reciprocating Continuous Pushing Device for a Cartoning Machine

CN220430651U · Utility Model Patent · Granted February 2, 2024

This patented continuous pushing device is designed for automatic cartoning machines. It combines a sliding frame, transverse moving structure, longitudinal moving structure, pushing rods and material-pressing devices.

The pushing assembly reciprocates in synchronization with the external conveyor. Products can therefore be pushed into folding cartons while the conveyor continues operating, reducing intermittent stops and improving cartoning efficiency.

The design also describes cooling and lubrication structures integrated into the pushing rods to help control operating temperature, reduce friction and support stable long-term movement.

  • Patent number: CN220430651U
  • Application number: CN202322115919.2U
  • Patent type: Utility model

Rotary Double-Ended Suction Device

CN211470023U · Utility Model Patent · Granted September 11, 2020

This patented rotary suction device is designed for high-speed material pickup and transfer. It includes a fixed base, ventilated fixed shaft, eccentric rotary plate, air-guide seat, suction-cup shaft and two symmetrically arranged suction-cup assemblies.

Unlike a conventional connecting-rod and swing-arm suction mechanism, the rotary arrangement supports faster continuous movement. Separate air passages supply the suction assemblies to improve suction strength and material-handling stability.

The device can be applied where cartons, paperboard blanks or other packaging materials must be picked up and transferred repeatedly during an automated packaging cycle.

  • Patent number: CN211470023U
  • Application number: CN202020085994.2U
  • Patent type: Utility model
  • Filing date: January 15, 2020
  • Grant and publication date: September 11, 2020

Full-Servo Automatic Cartoning Machine with Adjustable Stations

CN116605479A / CN116605479B · Invention Patent · Granted July 25, 2025

This patented full-servo automatic cartoning machine includes a product input device, loading device, folding-carton conveyor, guide bars, pressure plates and adjustable mounting mechanisms.

The guide bars and pressure plates can be repositioned horizontally through sliding frames and vertically through liftable mounting columns. Dedicated locking mechanisms secure each adjusted position.

This adjustable station design allows the cartoning machine to accommodate folding cartons of different dimensions, extending the available format range and reducing the amount of fixed-format hardware required during product changeovers.
