Therefore, only when the rotation shaft 51 rotates in the clockwise direction from the top view, the rotation disk 41 rotates, whereas the rotation disk 41 does not rotate.
Since the ratchet 543 is not connected to the pawl plate 541 with a gap therebetween, and the pawl plate 541 is mounted on the rotating shaft 51, the mounting of the ratchet 543 is not described, and thus the following design is also made in this embodiment: an annular boss 63 is further disposed on the upper surface of the bottom plate 61, the annular boss 63 is located below the ratchet wheel 543, a circle of second slide rail 64 is disposed on the upper surface of the annular boss 63, the bottom of the ratchet wheel 543 is clamped on the second slide rail 64 through a corresponding slide groove (not labeled in the figure), and the ratchet wheel 543 can slide along the second slide rail 64 to realize a rotation motion around the central axis thereof.

In addition, when the door panel 31 is located at the outer limit position, the door panel 31 just completely keeps the leakage hole 11 away, see fig. 8, i.e. at this time, the innermost side edge of the door panel 31 is just tangent to the hole wall of the leakage hole 11 near the outer side or very close to the hole wall of the leakage hole 11. Preferably, when the door panel 31 moves from the outer limit position to the inner limit position, the bottom of the weep hole 11 is completely closed by the door panel 31 when the door panel 31 moves to 1/8 of the total stroke.
The purpose of the above design is: since the powder falling from the discharge hole 11 needs to fall into the collecting and distributing cylinder 42 directly below when the door plate 31 is positioned at the outer limit position, the collecting and distributing cylinder 42 is positioned right below the discharge hole 11 during discharge, and when discharge is stopped, the door plate 31 starts to move inwards from the outer limit position, and meanwhile, the rotating disc 41 starts to rotate, so that the collecting and distributing cylinder 42 rotates, in order to avoid the condition that the discharge hole 11 is not closed in the process, the collecting and distributing cylinder 42 leaves the discharge point, so that the discharge hole 11 needs to be closed as soon as possible, and the door plate 31 specially positioned at the outer limit position is just positioned near the discharge hole 11 and slightly moves inwards for a certain distance (1/8 of the total stroke), so that the discharge hole 11 can be closed; thus, when the rotation shaft 51 rotates clockwise from the top view angle, and the door plate 31 starts to move inwards from the outer limit position, the rotation disc 41 slightly rotates by a certain angle (90/8 degrees), the door plate 31 can seal the bottom of the material leakage hole 11, and the material leakage hole 11 is sealed by the door plate 31 before the material leakage hole 11 leaves the material leakage point of the material leakage hole 11, so that the condition that powder does not fall into the material leakage hole 42 when falling is avoided.
The automatic batching device of the invention has the following functions: four different powder materials are sequentially dropped into the lower distributing cylinder 42 according to a preset component ratio, and then all powder materials are dropped into the lower material box a at one time by the distributing cylinder 42 filled with the four powder materials at a specific position, and then the material box a is transported to the next process.
The specific working principle is as follows:
When not in operation, the invention is in an initial state; at this time, the four door panels 31 are all located at the inner limit positions (see fig. 2,6 and 7), and the bottoms of the four discharge holes 11 are all closed; meanwhile, the four distributing cylinders 42 are respectively located under the four material leakage holes 11, that is, the central axis of each distributing cylinder 42 is collinear with the central axis of one of the material leakage holes 11, referring to fig. 1 and 2, the bottoms of the four distributing cylinders 42 are attached to the annular cushion layer 62 and are sealed by the annular cushion layer 62; meanwhile, a plurality of cartridges a (only two cartridges are shown in fig. 1) are also arranged on the belt 71 of the conveying mechanism 7, the intervals among the cartridges a are equal, the forefront cartridge a is positioned right below the notch I621 and the notch II 611, the area of the top opening of the cartridge a is larger than that of the notch I621/the notch II 611, namely, the projections of the notch I621 and the notch II 611 in the vertical direction can fall into the cavity of the cartridge a, and the depth of the inner cavity of the cartridge a can ensure that powder falling from the bottom of the collecting and distributing cylinder 42 cannot overflow after entering the cartridge a; the belt 71 is conveyed from the right side to the left side in fig. 1;
Preparation before work: for ease of understanding, four distribution cylinders 42 are respectively marked with four serial numbers i, ii, iii, iv in fig. 1 and 10 according to the rotation direction of the rotating disk 41, and four hoppers 2 are respectively marked with ①、②、③、④ four serial numbers in fig. 1 in a one-to-one correspondence with the four distribution cylinders 42; before starting, four kinds of powder to be mixed are required to be poured into the four hoppers 2 respectively, then a predetermined amount of powder contained in the hopper ① is poured into the distribution cylinder 42 with the reference number II, a predetermined amount of powder contained in the hopper ① and the hopper ② are poured into the distribution cylinder 42 with the reference number III, a predetermined amount of powder contained in the hopper ①, the hopper ② and the hopper ③ are poured into the distribution cylinder 42 with the reference number IV, and no powder is required to be poured into the distribution cylinder 42 with the reference number I;
When in operation, the device comprises: firstly, the motor 52 rotates positively, the motor 52 drives the rotation shaft 51 to rotate for a certain number of turns along the anticlockwise direction of the overlook angle, in this process, the first gear transmission assembly 53 drives the four door panels 31 to move radially outwards, and the second gear transmission assembly 54 does not drive the rotation disc 41 to rotate; when the door panel 31 moves to the outside limit position (see fig. 8), the motor 52 is temporarily stopped, in the process, the bottoms of the four material leakage holes 11 are opened, and the powder in the four hoppers 2 simultaneously falls down, wherein the powder in the distribution cylinder 42 with the reference number i falls into the powder contained in the hopper ①, the powder in the distribution cylinder 42 with the reference number ii falls into the powder contained in the hopper ②, the powder in the distribution cylinder 42 with the reference number iii falls into the powder contained in the hopper ③, and the powder in the distribution cylinder 42 with the reference number iv falls into the powder contained in the hopper ④;
After that, when the material leakage time reaches the preset time, the motor 52 is reversed, the motor 52 drives the rotating shaft 51 to rotate for a certain number of turns along the clockwise direction of the overlook angle, and in the process, the first gear transmission assembly 53 drives the four door panels 31 to move inwards in the radial direction, and the second gear transmission assembly 54 drives the rotating disc 41 to rotate; when the door panel 31 moves to the inside limit position, the motor 52 is temporarily stopped, in the process, the bottoms of the four material leakage holes 11 are closed, the rotating disk 41 rotates 90 degrees along with the four distributing cylinders 42 in the anticlockwise direction of the overlooking angle, and the distributing cylinders 42 with the reference number I move to the position where the distributing cylinder 42 with the reference number II is located, the distributing cylinder 42 with the reference number II moves to the position where the distributing cylinder 42 with the reference number III is located, the distributing cylinder 42 with the reference number III moves to the position where the distributing cylinder 42 with the reference number IV is located, and the distributing cylinder 42 with the reference number IV moves to the position where the distributing cylinder 42 with the reference number I is located; wherein, the bottom of the distributing cylinder 42 marked with IV will cross the gap I621 during the moving process, so when the distributing cylinder 42 marked with IV moves to the upper part of the gap I621, the powder in the distributing cylinder 42 will fall down completely and then fall into the material box a which stays at the lower part in advance; since the powder contained in the hopper ④ falls into the powder collection and distribution cylinder 42 with the number IV, four kinds of powder are filled into the powder collection and distribution cylinder 42, and therefore, when the powder in the powder collection and distribution cylinder 42 falls into the material box a, the powder filled in the material box a is the powder for completing the material distribution;
then, the motor 52 rotates forward again to drive the rotating shaft 51 to rotate a certain number of turns in the anticlockwise direction of the overlook angle, and at the same time, the conveying mechanism 7 is started to drive the upper material box a to move forward by one frame, so that the next material box a moves below the notch I621 and the notch II 611, after moving, a new material box a is added on the belt 71, and the added material box a needs to be placed at the initial end of the belt 71 (namely, the rightmost side of the belt 71 in the figure); subsequently, the automatic batching device continuously repeats the previous actions in a circulating way;
In the process of continuously repeating the cycle, one collecting and distributing cylinder 42 completes the batching after the motor 52 completes one forward rotation, then when the motor 52 rotates reversely, the collecting and distributing cylinder 42 completing the batching can cross the notch I621, so that all powder in the collecting and distributing cylinder 42 falls into the material box a below, and then the material box a is driven by the belt 71 to move forward until the powder box a is conveyed to the subsequent process.
Therefore, in the process of completing powder proportioning, the invention not only can proportioning a plurality of powder according to the preset proportion without weighing the powder one by one, but also omits the step of taking and placing the container in the patent with the application number 202210052114.5. Therefore, the automatic control device has the advantages of higher automation degree and higher efficiency.
In the above process, since the leaking time is the same, the ratio of the powder is determined by the aperture size of each leaking hole 11, for example, if the area of the leaking hole 11 below the hopper ② is twice the area of the leaking hole 11 below the hopper ①, the volume of the powder dropped from the hopper ② will be twice the volume of the hopper ① when the motor 52 is stopped after being rotated forward, so that the aperture size of each leaking hole 11 can be designed in advance according to the required blending ratio. In addition, since the weight of the blanking is determined by the time of the missing material, the time interval for stopping the motor 52 after the normal rotation can be set in advance according to the required final weight, thereby obtaining the material of the required weight. Here, the diameters of the respective weep holes 11 shown in the drawings of the present embodiment are uniform, so that four kinds of powders are as follows: 1:1:1 by volume.
This embodiment is applicable to the dosing of four different powders, which can be arranged in one cartridge a in a specific ratio and a specific total weight. If the number of powder types of the ingredients needed varies, the corresponding number of the parts or structures such as the hopper 2, the material leakage hole 11, the door plate assembly 3, the second gear 533, the opening 91, and the distributing cylinder 42 may be increased or decreased, for example, the powder materials of the ingredients needed include six different powder materials, the number of the hopper 2, the material leakage hole 11, the door plate assembly 3, the second gear 533, the opening 91, and the distributing cylinder 42 may be six, and the sizes of other parts or structures may be adaptively adjusted, for example, the size of the notch i 621 and the size of the distributing cylinder 42 may be adjusted.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
