In addition, one plate can be driven to move by one driving part and is matched with another plate connected with another driving part to realize control. Hereinafter, the following specific explanation will be made taking the use of three plate members and three transmission members as an example.

The quantitative component comprises three transmission parts and plates which are respectively arranged at output shaft ends of the three transmission parts, the three transmission parts are respectively a first transmission part 2, a second transmission part 3 and a third transmission part 4, the plates are respectively a first plate 21, a second plate 31 and a third plate 41, the output shaft end of the first transmission part 2 is fixedly connected with the first plate 21, the output shaft end of the second transmission part 3 is fixedly connected with the second plate 31, and the output shaft end of the third transmission part 4 is fixedly connected with the third plate 41; the first transmission piece 2 and the third transmission piece 4 are located on one side of the shell 1, the second transmission piece 3 is located on the other side of the shell 1, the second plate piece 31 is adjustably located in the through hole 11 and is arranged between the first plate piece 21 and the third plate piece 41, the first plate piece 21 and the second plate piece 31 are driven to form a first visible or disappearing quantitative chamber 113 in the through hole 11 through position adjustment of the first plate piece 21 and the second plate piece 31, and the second plate piece 31 and the third plate piece 41 are driven to form a second visible or disappearing quantitative chamber 114 in the through hole 11 through position adjustment of the second plate piece 31 and the third plate piece 41. Here, it can be understood by those skilled in the art that when the three plate members are driven by the driving member, respectively, the plate members can be driven to cooperate with each other when passing through the through hole 11 to generate two quantitative chambers, i.e., a first quantitative chamber 113 and a second quantitative chamber 114. The first and second quantitative chambers 113 and 114 are not limited in volume, and generally, for better quantitative control, the two quantitative chambers may have the same volume, that is, when the through hole 11 is a vertical hole with a uniform diameter, and when the three plates are spaced at the same distance on the axis of the through hole 11 (the three plates are arranged in parallel), the first and second quantitative chambers 113 and 114 have the same volume, so that the control of the volumes of the two materials can be realized by controlling the driving states of the three plates, and similarly, when the four plates are used, the three quantitative chambers may be present, which is not further limited and explained herein. In the implementation process, the first plate 21 and the second plate 31 are respectively driven to make the first quantifying chamber 113 and the second quantifying chamber 114 disappear after the positions of the first quantifying chamber and the second quantifying chamber are adjusted, meanwhile, the third plate 41 is driven to divide the through hole 11 into an upper space area and a lower space area, a discharge hole 115 is arranged below the third plate 41, and a chamber for filling materials is arranged above the third quantifying chamber; when the receiving place needs one unit capacity, the second plate 31 is driven to divide the chamber into two parts, namely, the material of one unit capacity in the first quantitative chamber 113 and the material of the other unit capacity in the second quantitative chamber 114 are formed, and then the third plate 41 and the second plate 31 are opened successively to enable the materials in the second quantitative chamber 114 and the first quantitative chamber 113 to fall down in sequence. It should be noted here that the above explanation is made only for two capacity chambers with the same unit capacity, and the capacity chambers used in practical application can be correspondingly increased according to the increase of the number of plate members, and the capacity of different capacity chambers can also be set according to the production requirement, and the setting only needs to adaptively adjust the relative distance between the two plate members.

A chamber which is located inside the housing 1 and through which the plate passes during driving by the transmission member; wherein, dust absorption mouth 5 has been seted up to one side of casing 1, this dust absorption mouth 5 intercommunication the cavity, here technical personnel can understand, because the driving medium and the plate that adopt are in the actual assembly back, it needs to have certain activity space in order to realize that it is flexible, because in the flexible in-process at the plate can lead to tiny material powder etc. to get into this cavity, influence the normal use of equipment after accumulating for a long time, consequently, dust absorption mouth 5 that is provided with can external dust extraction realize the cleaning action to the cavity, further improve the result of use of this kind of material batcher.

Since the adopted plate members are all the same in structure, and there may be different moving directions of the plate members in practical application, therefore, taking the plate member 21 as an example to make a structural explanation, the plate member 21 is a rectangular plate member, the plate member can be roughly divided into two parts, one part is a hole 211 which is located at the upper half end of the plate member 21 and penetrates through the plate member, the other part is a solid plate surface (i.e. a grid baffle surface 212) located at the lower half end of the plate member 21, the output shaft end of the transmission member 2 is connected to the connecting end 213 which is close to one side of the grid baffle surface 212, during the implementation action, the transmission member 2 drives the plate member 21 to reciprocate along the length direction, when the plate member 21 moves to the center of the hole 211 and is overlapped with the axis of the through hole 11, the material at this time can smoothly pass through the layer of the plate member 21, when the transmission member 2 drives the plate member 21 to continue to move to the grid baffle surface 212 and divide the through hole 11, the material stops at the level of the plate element 21.

Further, the size of the hole 211 is equal to or larger than the cross-sectional size of the through hole 11, so that when the center of the hole 211 coincides with the axis of the through hole 11, the material can smoothly pass through the hole to continuously fall, and the problem of inaccurate quantification caused by the plate occupying part of the volume of the through hole 11 is avoided.

Further, an air inlet 131 communicated with the cavity is further formed in the shell 1, and the air inlet 131 is arranged to balance air pressure in the cavity so as to achieve a normal dust collection effect of the dust collection port 5.

In addition, in order to ensure the effectiveness of dust collection, when the chamber is in a separated structural form of a first chamber 12 and a second chamber 13, an air inlet 131 is formed in the inner wall of any one of the first chamber 12 and the second chamber 13, and meanwhile, the other chamber is communicated with the dust collection port 5, wherein, as can be understood by those skilled in the art, in order to realize dust collection of the two chambers, the dust collection port 5 and the air inlet 131 are respectively distributed in the two chambers, so that the two chambers can be effectively acted and collected dust at the same time, and the dust collection effect is improved.
