Abstract

The utility model discloses an optional formula vibration screening device through all designing the water conservancy diversion mouth on the lower floor of screen cloth, detachable guide plate can be installed additional to water conservancy diversion mouth position department, and the water conservancy diversion of filter screen below is in normally open state, and the selectable switching of top water conservancy diversion mouth according to the technology demand. When the primarily screened tobacco flakes enter a secondary screening mode, if the guide plate above the screen is removed and the guide opening above the screen is closed, because the guide opening below the screen is in a normally open state, 2-6mm tobacco flakes are screened by the screen and then directly flow into a post-process, the tobacco flakes below 2mm are screened below the filter screen and enter a dust removal collection system through the guide plate and the guide opening; if the guide plates above and below the filter screen are installed simultaneously and the guide openings are opened simultaneously, the scraps below 2mm and the tobacco flakes between 2mm and 6mm are respectively guided out from different guide holes, so that the requirements of different process designs are met, and the flexible processing degree is improved. The utility model relates to a simply, low cost has better use value and popularization prospect.

Description

Selectable vibration screening device
Technical Field
The utility model belongs to the technical field of cigarette machinery, especially indicate a selectable formula vibrations screening plant.
Background
In the tobacco shredding production process, if the tobacco flakes are smaller in the shredding process, the tobacco flakes are shredded into powder, and the tobacco shredding production process has no use value. Therefore, in the existing shredding process, screening is carried out before shredding, most of the screened fragments are subjected to secondary screening, the fragments with the particle size of less than 2mm are collected into a dust removal system as scraps, and the tobacco sheets with the particle size of 2-6mm are directly processed in the post-process without shredding. With the requirement of flexible processing technology and high-grade cigarette processing, the secondary screening treatment needs more selection modes, and partial small and medium fragments can be selected to enter cut tobacco shreds and can be collected and treated in a centralized manner.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a selectable vibrations screening plant to when the solution needs to adjust the specification of screening, need change the problem of whole reciprocating sieve.
The utility model discloses a realize through following technical scheme:
an optional vibration screening device comprises a screen bracket with a groove-shaped main body, wherein a screen is arranged in the screen bracket;
the screen divides the screen support into a lower space and an upper space;
a first flow guide port communicated with the lower space and a second flow guide port communicated with the upper space are formed in the side wall of the screen support;
a lower guide plate is arranged in the lower space; a detachable upper guide plate is arranged in the upper space;
the lower guide plate is matched with the first guide port; the upper guide plate is matched with the second guide opening.
The upper guide plate and the lower guide plate are obliquely arranged along the axial center line of the screen support.
The second diversion port baffle is used for plugging the second diversion port.
The utility model has the advantages that:
the technical scheme is diversified and flexible in secondary screening specification, and the screening device with the shunting port and the detachable baffle is designed, so that 2-6mm small tobacco flakes can directly enter a cut tobacco shred procedure and can be collected in a centralized manner through the shunting port, and the processing requirements of different processes are met.

Description of the reference numerals
1 screen support, 2 screens, 3 lower guide plates, 4 upper guide plates, 11 lower spaces, 12 upper spaces, 13 first guide openings and 14 second guide openings.
Detailed Description
The technical solutions of the present invention are described in detail below by way of examples, which are only exemplary and can be used only for explaining and explaining the technical solutions of the present invention, but should not be construed as limiting the technical solutions of the present invention.
As shown in fig. 1 to 3, the application provides an alternative vibrating screening device, which mainly realizes the function of selective screening by determining whether 2-6mm tobacco flakes are reserved according to the process requirement in the shredding process.
The screening device comprises a screen support 1 with a groove-shaped main body, wherein a screen 2 is arranged in the screen support; the screen divides the screen support into a lower space 11 and an upper space 12; during screening, the tobacco flakes with the particle size of less than 2mm are screened below the screen and enter the lower space; 2-6mm tobacco flakes are screened by a screen and then directly flow into the post-process.
The side wall of the screen support is provided with a first flow guide port 13 communicated with the lower space, a lower flow guide plate 3 is arranged in the lower space, the lower flow guide plate is arranged in an inclined mode, and the tobacco flakes entering the lower space enter the dedusting and collecting system through the first flow guide port.
The second diversion port 14 is communicated with the upper space; a detachable upper guide plate 4 is arranged in the upper space; and the second diversion port baffle is used for plugging the second diversion port.
According to the process requirement, when the second flow guide port is closed by the second flow guide port baffle, and the upper flow guide plate is disassembled, the 2-6mm tobacco flakes are screened by the screen and directly flow into the post-process.
When the second flow guide port baffle is opened and the flow guide plate is installed, the scraps with the size less than 2mm and the tobacco flakes with the size of 2-6mm are respectively guided out from different flow guide holes, so that the requirements of different process designs are met.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
