The purpose of the above design is: since the powder falling from the material leaking hole 11 needs to directly fall into the container a below when the door panel 31 is located at the outer limit position, when the material leaks, the container a is located right below the material leaking hole 11, and then once the material leaking is stopped, the door panel 31 starts to move inwards from the outer limit position, and meanwhile, the tray 4 also starts to rotate, so that the container a placed above the tray 4 also rotates along with the container a, and in order to avoid the situation that the material leaking hole 11 is not closed in the process, the container a already leaves the material dropping point, the material leaking hole 11 needs to be ensured to be closed as soon as possible, therefore, the door panel 31 located at the outer limit position is specially and just located near the material leaking hole 11, and the door panel 31 slightly moves inwards for a certain distance (1/8 of the total stroke), so that the material leaking hole 11 can be closed; thus, when the rotating shaft 51 rotates clockwise along the top view and the door panel 31 starts to move inwards from the outer limit position, the tray 4 rotates a certain angle (90/8 degrees) slightly, the door panel 31 can close the bottom of the material leaking hole 11, so that the door panel 31 closes the material leaking hole 11 before the container a leaves the material dropping point of the material leaking hole 11, thereby ensuring that the powder does not fall into the container a when falling.
The batching device of the invention has the functions as follows: four different powders are dosed into the containers a according to predetermined proportions and amounts, and during continuous operation, the required proportions and weights can be dosed in the containers a. The working principle is as follows:
when the door panel is not in operation, the invention is in an initial state, and at the moment, the four door panels 31 are all located at the inner limit positions (see fig. 2, 6 and 7); meanwhile, the positions of the four partition plates 92 are staggered with the positions of the four discharge holes 11 in the vertical projection, referring to fig. 1, in the vertical projection, each partition plate 92 is respectively located in the middle of the connecting line of two adjacent discharge holes 11, so that the blanking point of each discharge hole 11 is located in the middle of each sector area 4a (or can be said to be located on the symmetry axis of the sector surface of each sector area 4 a).
Preparation before work: in fig. 1 and 10, four sector areas are respectively marked as four serial numbers i, ii, iii and iv according to the rotation direction of the tray 4, and in fig. 1, four hoppers 2 are respectively marked as four serial numbers i, ii, iii and iv in a one-to-one correspondence manner with the four sector areas; before starting, four kinds of powder materials needing to be proportioned are poured into the four hoppers 2 respectively, and then containers a are placed in the four fan-shaped areas 4a respectively, wherein the container placed in the fan-shaped area I is an empty container a, the container a placed in the fan-shaped area II needs to be poured into powder materials contained in a hopper (I) with a preset amount, the container a placed in the fan-shaped area III needs to be poured into powder materials contained in the hopper (I) and the hopper (II) with a preset amount, and the container a placed in the fan-shaped area IV needs to be poured into powder materials contained in the hopper (I), the hopper (II) and the hopper (III) with a preset amount;
when in work: firstly, the motor 52 rotates forward, the motor 52 drives the rotating shaft 51 to rotate a certain number of turns along the counterclockwise direction of the overlooking angle, in the process, the first gear transmission component 53 drives the four door panels 31 to move radially outwards, and the second gear transmission component 54 does not drive the tray 4 to rotate; when the door plate 31 moves to the outer limit position (see fig. 8), the motor 52 is stopped temporarily, in the process, the bottoms of the four material leaking holes 11 are opened, and powder in the four hoppers 2 simultaneously fall down, wherein the powder in the hopper (I) can fall into the container a in the fan-shaped area I, the powder in the hopper (II) can fall into the container a in the fan-shaped area II, the powder in the hopper (III) can fall into the container a in the fan-shaped area III, and the powder in the hopper (IV) can fall into the container a in the fan-shaped area IV;
then, when the material leakage time reaches the preset time, the motor 52 rotates reversely, the motor 52 drives the rotating shaft 51 to rotate for a certain number of turns clockwise along the overlooking angle, in the process, on one hand, the first gear transmission component 53 can drive the four door panels 31 to move radially inwards, and on the other hand, the second gear transmission component 54 can drive the tray 4 to rotate; when the door panel 31 moves to the inner limit position, the motor 52 is stopped temporarily, in the process, the bottoms of the four material leaking holes 11 are closed, all the fan-shaped areas on the tray 4 rotate forward by 90 degrees and move to the next grid, namely the fan-shaped area I moves to the position of the original fan-shaped area II, the fan-shaped area II moves to the position of the original fan-shaped area III, the fan-shaped area III moves to the position of the original fan-shaped area IV, and the fan-shaped area IV moves to the position of the original fan-shaped area I; then, as the powder in the container a on the fan-shaped area IV is completely proportioned (namely, the powder contained in the hopper I, the hopper II, the hopper III and the hopper IV is loaded according to a preset proportion), the container a on the fan-shaped area IV needs to be taken down, and after the container a is taken down, a new empty container a needs to be placed on the fan-shaped area IV;
then, the motor 52 rotates forward again to drive the rotating shaft 51 to rotate for a certain number of turns along the counterclockwise direction of the overlooking angle, and then the previous movement and action are repeated;
in the subsequent process, after the motor 52 completes each forward rotation and reverse rotation, the powder material is mixed in one of the containers a, and after the mixing is completed, the corresponding container a needs to be taken down and replaced by a new empty container a.
Under the continuous and continuous work, the invention can finish the ingredients one time after another, and each finished ingredient is contained in one container a. Therefore, in the whole process, the powder materials can be mixed according to the preset proportion without weighing the powder materials one by one. When various powder materials need to be mixed in the field of food, the complex weighing step can be omitted after the mixing device is applied, so that the working efficiency can be greatly improved.
The taking and placing of the container a can be manually completed by workers, and a set of corresponding automatic mechanical taking and placing device can be specially designed to complete the taking and placing.
In the process, because the material leaking time is the same, the proportion of different powder materials is determined by the aperture size of each material leaking hole 11, for example, if the area of the material leaking hole 11 below the hopper II is twice of the area of the material leaking hole 11 below the hopper I, the volume of the powder material falling from the hopper II is twice of that of the hopper I when the motor 52 stops after rotating forwards, and therefore the aperture size of each material leaking hole 11 is designed in advance according to the required material proportioning proportion to obtain the required material proportioning proportion. In addition, since the blanking weight is determined by the material leakage time, the shutdown time interval after the forward rotation of the motor 52 can be preset according to the required final weight, so that the material with the required weight can be obtained. Wherein, the aperture of each material leaking hole 11 shown in the drawings of the description of the embodiment is consistent, so that the four powders are according to 1: 1: 1: 1, are dosed.
This embodiment is suitable for the dosing of four different powders, which can be arranged in a container a according to a specific ratio and a specific total weight. If the amount of the powder species to be blended varies, the number of the hopper 2, the hopper discharge hole 11, the door plate assembly 3, the second gear 533, the opening 61, and the partition plate 92 may be increased or decreased, for example, the powder species to be blended may include six different powder species, and the number of the hopper 2, the hopper discharge hole 11, the door plate assembly 3, the second gear 533, the opening 61, and the partition plate 92 may be designed to be six.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
