Description

Technical Field

[0001] The utility model relates to the technical field of a material pot of a wet granulator, in particular to a pneumatic locking mechanism for a pot cover of a material pot of a wet granulator. Background Art

[0002] The wet granulator can grind the wet powder into the required particles, and can also crush the blocky dry materials into the required particles. The mechanical transmission system is completely enclosed in the machine body and is equipped with a lubrication system. The whole machine runs smoothly and is currently used on a large scale.

[0003] When the wet granulator is in use, the material pot it is equipped with needs to be sealed to prevent external debris from falling in. Traditional material pot covers are mostly fastened by butterfly nuts. During processing, a threaded guide rod is set on the top of the material pot, a through hole is set on the pot cover, and finally the pot cover is installed and fixed by butterfly nuts. However, when this structure is used, although the butterfly nuts are easy to disassemble, generally multiple butterfly nuts are set, which leads to a large workload during manual disassembly or installation, and is not conducive to the rapid locking and loosening of the material pot cover. Utility Model Content

[0004] The utility model aims to provide a pneumatic locking mechanism for a pot cover of a wet granulator material pot, aiming to realize rapid automatic locking and rapid automatic loosening of the pot cover of the wet granulator material pot during use.

[0005] To achieve the above-mentioned purpose, the utility model provides a pneumatic locking mechanism for a pot cover of a wet granulator material pot, comprising a cylinder cover, a locking block is installed on the cylinder cover, and an auxiliary device;

[0006] The auxiliary device includes a cylinder seat, an angle cylinder, a clamping shaft, a positioning block and a sensing component. The cylinder seat is located on one side of the cylinder head. The angle cylinder is fixedly connected to the cylinder seat and is located on the top of the cylinder seat. The clamping shaft is connected to the output end of the angle cylinder and is located on the output end of the angle cylinder. The positioning block is installed between the angle cylinder and the clamping shaft. The sensing component is arranged on one side of the cylinder seat close to the positioning block.

[0007] After the upper air inlet of the corner cylinder is ventilated, the cylinder shaft rotates 90° and moves downward, and after the lower air inlet of the corner cylinder is ventilated, the cylinder shaft moves upward and rotates 90°.

[0008] Wherein, the sensing component includes a fixed bracket and a detection component, the fixed bracket is fixedly connected to the cylinder seat and is located on one side of the cylinder seat; the detection component is arranged on the fixed bracket.

[0009] Among them, the detection component includes an upper detection switch and a lower detection switch. The upper detection switch is detachably connected to the fixed bracket and is located above the fixed bracket; the lower detection switch is detachably connected to the fixed bracket and is located below the fixed bracket.

[0010] Among them, the model of the upper detection switch is CDJ10-I 2A12AP.

[0011] Among them, the model of the lower detection switch is CDJ10-I 2A12AP.

[0012] For the pneumatic locking mechanism of the lid of the material pot of the wet granulator of the present utility model, a locking block is installed on the cylinder head. The rotary cylinder is fixed to the platform plate through a cylinder seat. After the air inlet on the rotary cylinder is ventilated, the cylinder shaft rotates 90° and moves downward, thereby realizing the action of locking the cylinder head. After the air inlet under the rotary cylinder is ventilated, the cylinder shaft moves upward and rotates 90°, thereby realizing the unlocking action of the cylinder head. The output end of the rotary cylinder is connected to the pressing shaft, and a positioning block is installed in cooperation at the connection. When the pressing shaft moves downward, the positioning block moves downward accordingly. When the locking mechanism is fully locked or relaxed, it is necessary to detect and sense the in-place signal through the sensing component and transmit the signal to the controller before the next action can be carried out. In this application, by setting the transmission structure of the rotary cylinder, the pressing shaft is driven to move upward or downward through the action of the rotary cylinder, realizing the relaxation or locking of the locking block, so that the cylinder head can be automatically relaxed or locked. Compared with the traditional method of fixing and relaxing with a wing nut, it will be faster and can reduce the manual operation intensity, thereby realizing the rapid automatic locking and rapid automatic relaxation of the lid of the material pot of the wet granulator during use.
