Traditional sieving also has a low sieving rate for dry powders, with large particles remaining on the screen and affecting subsequent sieving. Therefore, improving sieving efficiency and reducing operator safety hazards remains a challenging problem that has been continuously explored by those skilled in the art. Utility Model Content

[0029] The above describes the structure of a wet sieve. A brief explanation of its working principle is as follows:

[0030] Before the equipment is put into operation, the corresponding solvent needs to be prepared. The solvent is put into the storage cylinder 805 in advance. When the equipment is in operation, the operator is in the control room and puts the dry agent to be wet sieved and the screen (usually 300 mesh) on the moving platform 402. The equipment automatically puts the dry agent onto the screen through the material cylinder gripper (103) of the six-axis robotic arm 1. Then, the liquid replenishment transfer table 8 pours the solvent from the storage cylinder 805 into the solution container 802 through the liquid pouring component 804. After that, the six-axis robotic arm 1 immerses the prepared solvent into the screen 202 at a uniform speed. Then, the agent and the screen 202 are placed on the vibrating plate 201 of the vibrating screen 2. The pull-down component 204 covers the screen cover 205 on the screen 202. The vibration motor drives the vibrating plate 201 to vibrate and perform sieving. After the sieving time is up, the reagent settles. The lifting component 203 lifts the screen cover 205, and the screen gripper 104 of the six-axis robotic arm 1 picks up the screen 202. Part of the solvent is recovered at the funnel 803, and the reagent, usually in a wet state at the bottom of the screen, is placed on the replenishing screen frame 806 to dry, thus completing the wet sieving.

The inlet and outlet windows 4 can be opened to allow materials to enter and exit, and are closed during screening to separate the explosion-proof workshop and the control space. The explosion-proof control cabinet 5 controls the operation of each component.

[0032] In a preferred embodiment, the robotic arm 1 includes a base 105, on which a six-axis robot 101 is mounted. The end of the six-axis robot 101 has a gripper seat 102, on which a screen gripper 104 and a material cylinder gripper 103 are mounted simultaneously.

[0033] In a preferred embodiment, the inlet / outlet window 4 includes: a fixed plate 404, which is connected to the explosion-proof door 7.

[0037] The above describes the structure of the dry screen. A brief explanation of the working principle of the dry screen is as follows:

[0038] During operation, the operator in the control room places the medicine to be dry-sieved and the sieve (generally 20-60 mesh) on the movable platform 402. The equipment uses a six-axis robotic arm 1 to place the sieve 202 onto the vibrating plate 201. Then, the medicine is poured into the sieve 202. The pull-down assembly 204 of the vibrating screen 2 pulls down, covering the sieve cover 205 onto the sieve 202. The scraper lifting assembly 208 drives the scraper 207 to extend into the sieve, and the scraper (207) is activated to force sieving. After sieving, the six-axis robotic arm 1 pours the sieved medicine into the vibrating funnel 303, where the medicine is collected by the material cylinder below the vibrating funnel 303, thus completing the dry sieving process.
