Description

Technical Field

[0001] The utility model relates to the technical field of wet granulators, in particular to a lever-type pneumatic cover-opening mechanism for a wet granulator. Background Art

[0002] A wet granulator generally consists of a frame, a driving and stirring mechanism, a cutter mechanism, a discharging device, a cylinder head device, a cover-lifting mechanism, an electric control mechanism and a pneumatic control mechanism.

[0003] Wet granulation refers to a method of adding a binder to drug powder and making the powder agglomerate together by the bridging or bonding action of the binder to prepare granules. A wet granulator is a device that uses a high-speed rotating granulating knife to cut the material mixed with a binder into wet granules.

[0004] The existing cover-lifting mechanisms of granulators are generally pneumatic spring cover-opening mechanisms (using springs or pneumatic springs to achieve cover-lifting or cover-closing), or non-powered heavy hammer cover-opening mechanisms. However, when opening and closing the cylinder head, the manual workload during closing is relatively large and it is inconvenient to use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a lever-type pneumatic cover-opening mechanism for a wet granulator, which can automatically open and close the cylinder head of the material cylinder of the wet granulator, reduce the manual workload and achieve a better automatic use effect.

[0006] To achieve the above purpose, the utility model provides a lever-type pneumatic cover-opening mechanism for a wet granulator, which includes a cylinder head and a mounting seat. The mounting seat is located on one side of the cylinder head, and an auxiliary device is further included;

[0007] The auxiliary device includes a cylinder, a material cylinder, a bracket, a swing arm, a connecting shaft and a signal detection component. The cylinder is installed on the mounting seat through a cylinder seat. The material cylinder is fixed on a platform plate. The bracket is fixed on a flat plate. The swing arm is hinged to the bracket through a middle pin shaft, and the end of the swing arm is connected to an action rod through a guide shaft. A guide sleeve is arranged outside the action rod, and the guide sleeve is fixed on the flat plate. The connecting shaft is threadedly connected to the piston rod of the cylinder and threadedly connected to the action rod, and is located between the piston rod and the action rod. The signal detection component is arranged on one side of the cylinder close to the connecting shaft.

[0008] Wherein, the signal detection component includes a mounting frame, a limit guide block, a guide rod and a switch component. The mounting frame is fixedly connected to the cylinder and is located on the top of the cylinder; the limit guide block is welded on the connecting shaft; the guide rod is fixedly connected to the mounting frame and is slidably connected to the limit guide block and is located on the mounting frame; the switch component is arranged on the upper and lower sides of the mounting frame.

[0009] Among them, the switch member includes a first detection switch and a second detection switch. The first detection switch is detachably connected to the mounting bracket and is located above the mounting bracket; the second detection switch is detachably connected to the mounting bracket and is located below the mounting bracket.

[0010] Among them, the model of the first detection switch is LJ18A3-8-Z / BX.

[0011] Among them, the model of the second detection switch is LJ18A3-8-Z / BX.

[0012] For a lever-type pneumatic opening and closing mechanism of a wet granulator of the present utility model, when the cylinder head is opened, the air cylinder drives the action rod to move downward. When the cylinder head is fully opened, position detection needs to be performed by a signal detection component. After the signal is transmitted to the controller, the controller can perform the next action. When the cylinder head is closed, the air cylinder drives the action rod to move upward. When the cylinder head is fully closed, position detection needs to be performed by a signal detection component. After the signal is transmitted to the controller, the controller can perform the next action. This application adopts a design consisting of a bracket, a swing arm, a pin shaft, an air cylinder, and a guide shaft to form a three-hinge kinematic pair and a slider kinematic pair. Its degree of freedom is one, the structure is simple, the action is stable, and it can realize the automatic opening and closing of the cylinder head, effectively reducing the manual workload. Furthermore, it can realize the automatic opening and closing of the cylinder head of the material cylinder of the wet granulator, reduce the manual workload, and achieve a better automation use effect.
