Proportioning device with dustproof structure for reagent production

Abstract

The invention discloses a proportioning device with a dustproof structure for reagent production. The proportioning device comprises a stirring mechanism and a dustproof mechanism, the stirring mechanism comprises a fixing frame, a sliding groove, a first motor, a first connecting plate and a connecting rod, a first through groove is formed in the surface of the fixing frame, the sliding groove is fixedly connected with the surface of the fixing frame, and the sliding groove is slidably connected with a sliding block; the sliding block is fixedly connected with a screw sleeve, the first motor is fixedly connected with the surface of the fixing frame, the first motor is fixedly connected with the screw rod, the screw rod is fixedly connected with the screw sleeve, the first connecting plate is fixedly connected with the surface of the fixing frame, the first connecting plate is rotationally connected with the screw rod, and the connecting rod is fixedly connected with the sliding block; and the connecting rod is fixedly connected with a third connecting plate. The screw rod is driven to rotate through forward rotation and reverse rotation of the first motor, the screw rod rotates to drive the screw sleeve to move back and forth along limiting positions of the sliding block and the sliding groove, and the sliding block moves back and forth to drive the stirring rod to move back and forth for full stirring.

Description

technical field [0001] The invention relates to a proportioning device, in particular to a proportioning device with a dust-proof structure for reagent production. Background technique [0002] Reagents, also known as biochemical reagents or reagents, are mainly pure chemicals used in chemical reactions, analytical tests, research experiments, teaching experiments, and chemical formulas. They are generally divided into general reagents, high-purity reagents, analytical reagents, and instrumental analysis according to their uses. Reagents, clinical diagnostic reagents, biochemical reagents, inorganic ion chromogenic reagents, etc., reagents are made of a mixture of various materials. [0003] The traditional mixing device lacks dust-proof measures for powdery materials during use. Dust will be generated when the material is dumped and stirred, which will affect the operating environment. Moreover, the structure and function are relatively simple. Most mixing devices do not su...
