Embodiment 1

[0023] like figure 1 As shown, this embodiment provides a multi-stage screening device, including a screening hopper 4, and the screening hopper 4 includes a primary screening mechanism 4-1 and a secondary screening mechanism 4-2 arranged in sequence from top to bottom. The primary screening mechanism 4-1 includes the feeding screen 4-1.1 and the secondary screen 4-1.2 arranged in sequence from top to bottom. Above the feeding screen 4-1.1 is a reciprocating rolling assembly 1, and the reciprocating rolling assembly 1 includes a Roller 1-2 and moving assembly 1-1, above the feeding screen 4-1.1 is provided with a load-bearing plate 2 parallel to the feeding screen 4-1.1, the moving assembly 1-1 includes a moving bracket 1-1.1 and a load-bearing plate 1-1. The driving cylinder 1-1.2 on the plate 2 is used to drive the moving bracket 1-1.1. The moving bracket 1-1.1 includes a horizontal connecting plate 1-1.1 / 1 fixedly connected with the piston rod of the driving cylinder 1-1.2 ...

Embodiment 2

[0027] This embodiment is further optimized on the basis of Embodiment 1, specifically:

[0028] A horizontal rotating shaft 6 is provided below the tertiary screen 4-2.1, and the vibration assembly 4-2.2 includes a motor 4-2.2 / 1 that drives the horizontal rotating shaft 6 to rotate and an eccentric wheel group 4-2.2 / 2 that is keyed on the horizontal rotating shaft 6. , two connecting ears 8 are symmetrically arranged between the primary screening mechanism 4-1 and the secondary screening mechanism 4-2, and two guide grooves are symmetrically dug on the side wall of the primary screening mechanism 4-1, and the connecting ears 8 One end is fixedly connected with the secondary screening mechanism 4-2, and the other end is slidingly matched with the guide groove, which ensures the stability of the device during the vibration screening process.

Embodiment 3

[0030] like figure 2 and image 3 As shown, this embodiment is further optimized on the basis of Embodiment 2, specifically:

[0031] There are wavy rolling teeth 1-2.1 evenly distributed on the outer circumference of the pressing roller 1-2, and a number of scrap gears 5 are keyed on the horizontal shaft 6, and the scrap gear 5 is evenly distributed on the outer circumference. The crushing gear 5-1 can further crush the powder through the crushing gear 5 to ensure the screening effect.

Abstract

The invention discloses a multi-stage screening device, which relates to the technical field of traditional Chinese medicine processing equipment. The invention includes a sieve hopper. The sieve hopper includes a primary screening mechanism and a secondary screening mechanism. A reciprocating rolling assembly is arranged above the primary screening mechanism. The rolling assembly includes a pressing roller and a moving assembly. A load-bearing plate parallel to the feeding screen is arranged above the feeding screen. The moving assembly includes a moving bracket and a driving cylinder. The moving bracket includes a horizontal connecting plate fixedly connected to the piston rod of the driving cylinder. And the two mounting frames symmetrically arranged on the lower surface of the horizontal connecting plate, two grooves corresponding to the two mounting frames are dug on the load-bearing plate, the ends of the two mounting frames are respectively connected to the rotating shaft through the two grooves, and the pressure roller is sleeved on the On the rotating shaft, the powder of the present invention passes through the three-stage screening of the feeding screen, the secondary screen and the third screen in order to ensure the screening quality of the powder, and through rolling and vibration, the screening and circulation of the powder are ensured. , which improves the screening efficiency.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine processing equipment, in particular to a multi-stage screening device. Background technique [0002] After some Chinese medicinal materials are picked and dried, they need to be crushed before use. Now most Chinese medicinal materials are used in a reasonable combination and compatibility. This requires mixing various powdered Chinese medicinal materials. The existing technology usually It is to manually screen and remove impurities from powdered medicinal materials, and then mix and match various powdered medicinal materials, which makes the work efficiency low, and manual screening cannot guarantee the screening quality. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is: in order to solve the problem that the existing manual screening cannot guarantee the quality of powder screening, the present invention provides a multi-stage screening device. ...
