Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

Example 1:

referring to fig. 1 to 3, the present embodiment provides a powder feeder, including: a hopper 101, and at least two hoppers 102 connected to the hopper 101 through a feed pipe 104, respectively; the side wall of the feed box 101 is also provided with an air inlet pipe 103; a discharge pipe 105 is also provided at the lower end of the hopper 101. (it should be noted that the figures of this embodiment only show the connection between the bin 101 and a hopper 102)

More specifically, a feeding pipe 106 adapted to be connected with the conveying pipe 104 in a matching manner is arranged on the side wall of the feed box 101; and a control valve 107 adapted to control the opening and closing of the feed pipe 106 is provided at the mating portion of the feed pipe 104 and the feed pipe 106. The loudness independent control of the powder transportation between the hoppers 102 and the bins 101 can be performed through the control valves 107, that is, only one powder transportation process between one hopper 102 and one bin 101 can be started each time, or the powder transportation processes between the hoppers 102 and the bins 101 can be started in sequence, which is not absolutely limited in this embodiment, that is, when the powder transportation process between each hopper 102 and one bin 101 needs to be controlled individually, the loudness independent control can be performed through the corresponding control valve 107.

It should be noted that a back-blowing suction mechanism is also provided at the top of the material box 101.

In an alternative implementation case, referring to the drawings of the present embodiment, the back-blowing type suction mechanism includes a dust cover 110 disposed on the top of the bin 101 and penetrating through the bin 101, a filter (not shown) disposed between the dust cover 110 and the bin 101, a transition joint 111 integrally disposed on the top of the dust cover 110, and a negative pressure generator 112 disposed on the top of the transition joint 111, wherein the negative pressure generator 112 is adapted to penetrate through the bin 101 through the transition joint 111 to form a vacuum environment for the bin 101. Wherein the dust cover 110 is further connected with a blowback assembly. In the embodiment, the negative pressure generator 112 is used for forming the material box 1 into a vacuum box body, and the structure of the vacuum box body can realize the purpose of sucking materials from the hopper 102 under the condition of negative pressure in a vacuum mode, so that powder in the hopper 102 can efficiently enter the material box 101.

Since the hopper 101 of the present embodiment is adapted to a plurality of hoppers 102, the hopper 101 needs to be made into a vacuum box environment before sucking materials for different hoppers 2 each time to generate a negative pressure absorption effect on the powder in the hopper 102. In this case, in consideration of the situation that the powder attached to the inner wall of the hopper 101 is prevented from entering the negative pressure generator 112 before the powder of the next hopper 102 enters the hopper 101 during the process of vacuumizing the hopper 101, the filter screen is provided in the embodiment, so that the negative pressure generator 112 only forms a vacuum environment in the hopper 101, and no powder enters the negative pressure generator 112. Optionally, the negative pressure generator 112 in this embodiment may also be replaced by an exhaust fan, that is, the use requirement of this embodiment can be met as long as the negative pressure environment of the material box 101 can be formed.

After a period of use, a certain amount of powder may be attached to the screen, so that the powder attached to the screen may be discharged from the hopper 101, taking into account the need to clean the screen. This embodiment achieves the above-mentioned object through the blowback assembly.

In detail, the blowback assembly includes a ring pipe (not shown) coupled to the transition joint 111 in a penetrating manner (i.e., the ring pipe is built into the transition joint pipe), a pulse valve 113 connected to the ring pipe through a connection pipe 114, and a vent pipe 115 connected to the pulse valve 113; an air storage tank (not shown) is connected to the end of the air pipe 115 far away from the pulse valve 113. The blowback assembly is started to release the pulse airflow to blow the powder adsorbed on the filter screen back into the bin 101 so that the powder passes through the discharge pipe 105 of the bin 101 under the action of the pulse airflow and finally enters the powder externally-connected conveying pipe. After the above process is completed, the bin 101 is vacuumized to form a vacuum environment in the bin 101.

In addition, the discharging pipe 105 of this embodiment is connected to a powder externally-connected conveying pipe, and the butt joint between the powder feeding machine of this embodiment and the next processing procedure of powder is realized through the powder externally-connected conveying pipe.

In addition, the hopper 102 of the present embodiment is provided with a material inlet 108, and the material inlet 108 is provided with a cover plate 109 adapted to be opened. For the material conveying pipe 104, in an optional case, the material conveying pipe 104 is an inclined pipeline structure which is obliquely arranged relative to the horizontal plane, and the height of the hopper 102 can be reduced under the condition of the inclined pipeline structure, so that powder can be conveniently put into the hopper 102, and the operation difficulty of feeding is reduced. In an alternative embodiment, the feed delivery pipe 104 is a straight pipe structure arranged parallel to the horizontal plane. Therefore, the present embodiment is not limited to the specific pipe condition of the feed delivery pipe 104 with respect to the horizontal plane.

In summary, in the powder feeder of the embodiment, since one hopper 101 is connected to a plurality of hoppers 102, so that the powder can be stored in the plurality of hoppers 102, and thus, the powder in the plurality of hoppers 102 can be sequentially loaded into the hopper 101, so that in the process of loading the next hopper 102 after the loading of one hopper 102 is finished, the loaded hopper 102 can be stored, in this process, the continuous operation of part of the hopper 101 can be maintained without closing the whole operation of the hopper 101, and thus, the overall efficiency of the powder loading process is improved. Under the structure, even if various powder materials need to be loaded, the corresponding powder materials can be correspondingly stored through different hoppers 102, so that the loading operation of different powder materials is sequentially realized in the process of not stopping the operation of the feed box 101.

The concrete implementation principle of the powder material loading machine has been adopted in this embodiment as follows:

the vacuum environment in the bin 101 is achieved by the negative pressure generator 112, and one or more hoppers 102 suck the powder in the hopper 102 into the bin 101 through the conveying pipe 104 between the hopper and the bin 101. After all the powder in the hopper 102 enters the material box 101, gas is introduced into the material box 101 through the gas inlet pipe 103, so that the powder in the material box 101 can naturally pass through the discharge pipe 105 of the material box 101 and finally enter the powder externally-connected conveying pipe, and thus, the processes of feeding and outputting the powder in the hopper 102 are completed.
