Embodiment 1

[0030] Such as figure 1 As shown, the drug screening mechanism includes a frame 1, at least two screening mechanisms 2 and a conveyor belt 3, the screening mechanism 2 is fixed on the frame 1, and the screening mechanisms 2 are arranged obliquely and arranged equidistantly from top to bottom, The conveyor belt 3 is connected with the screening mechanism 2, and the screening mechanism 2 includes a screen cloth 22; between adjacent screening mechanisms 2, the mesh diameter of the screen cloth 22 on the screening mechanism 2 above is larger than that of the screen below. The mesh diameter of the screen cloth 22 on the branch mechanism 2.

[0031] According to the difference between the powder diameters of different drugs, the mesh diameter of the screen 22 is set, that is, the sieving mechanism 2 at the top separates the drug with the largest powder diameter, and the other sieving mechanisms 2 separate the drugs from top to bottom. The diameter of the powder gradually decreases,...

Embodiment 2

[0033] Such as figure 2 As shown, this embodiment is further improved on the basis of embodiment 1. The screening mechanism 2 also includes a frame body 21, an elongated hole 23 provided on the side of the frame body 21, a top strip 24 slidingly arranged in the elongated hole 23, the screen cloth 22 is fixed in the frame body 21, and The bar 24 is located below the screen cloth 22, and the top of the top bar 24 is in contact with the bottom of the screen cloth 22 and makes the screen cloth 22 protrude upward; Cylinder 25, the flexible end of cylinder 25 is connected with top bar 24.

[0034] The cylinder 25 drives the top bar 24 to move, and the top bar 24 continuously moves to make different positions on the screen 22 protrude, thereby driving the powder on the screen 22 to move, so that the medicine with a smaller powder diameter falls through the screen 22 .

[0035] This embodiment overcomes the shortcoming of dust flying in the traditional vibrating screening mechanism...

Embodiment 3

[0037] Such as image 3 As shown, this embodiment is further improved on the basis of embodiment 2. The top bar 24 includes a rectangular bar 241, a semicircular bar 242 arranged at the top of the rectangular bar 241, a shaft 243 arranged at both ends of the rectangular bar 241 and a bearing 244 sleeved on the shaft 243. In contact with the screen 22, the bearing 244 is slidably disposed in the elongated hole 23.

[0038] The top of top bar 24 is set as semicircle bar 242, can make the contact position of top bar 24 and screen cloth 22 smooth, and contact area is bigger, prevents top bar 24 from scratching screen cloth 22 in motion process, has greatly increased the present invention. service life.

Abstract

The invention discloses a drug screening mechanism which comprises a rack, at least two screening mechanisms and a conveying belt. The screening mechanisms are fixed on the rack, arranged in an inclining mode, and arranged in an equidistance mode from top to bottom. The conveying belt is connected with the screening mechanisms. Each screening mechanism comprises screen cloth. With respect to every two adjacent screening mechanisms, the mesh diameter of the screen cloth on the upper screening mechanism is larger than the mesh diameter of the screen cloth on the lower screening mechanism. The drug screening mechanism has the advantages of being capable of separating multiple drugs at one time and high in efficiency, and lowering procurement cost for drug manufacturers at the same time.

Description

technical field [0001] The invention relates to medicine production equipment, in particular to a medicine screening mechanism. Background technique [0002] In the drug production line, how to separate different drugs from the powder mixed with multiple drugs has always been a difficult problem in this field. [0003] At present, the separation is mainly carried out by means of filter sieve, but the existing separation device has only one filter sieve, and only one drug can be separated at a time, so the efficiency is low. In addition, existing separation devices can only separate a single drug in a targeted manner. If multiple drugs are to be separated, multiple separation devices of different types need to be purchased, which greatly increases the operating costs of drug manufacturers. Contents of the invention [0004] The purpose of the present invention is to overcome the disadvantages of the prior art that only one drug can be separated at a time, low efficiency an...
