Description

Technical Field

[0001] The utility model belongs to the technical field of feeding equipment, in particular to a powder feeding device. Background Art

[0002] Before making hot pot base, you need to weigh the powders such as pepper powder, pepper powder, chicken powder, etc. according to the proportion, put them into the mixer for even mixing, then pour them out and send them to the next workstation for subsequent processing.

[0003] Before adding the powder, the worker weighs the various powders according to the proportion and puts them into powder bags. The powder bags are then placed on a transfer vehicle and transferred to one side of the mixer. The powders are then moved to the lifting mechanism on one side of the mixer in turn, so that the lifting mechanism lifts the powder bag and the worker to the same height as the hopper. Finally, the worker lifts the powder bag with one hand and transfers it to the hopper. With the other hand, he picks up a blade and cuts the powder bag open, thus realizing the addition of the powder.

[0004] During this process, the powder bags need to be transferred many times, which is time-consuming and labor-intensive. Workers lift the powder bags into the hopper many times, which easily makes them tired. If they cannot control it steadily, the uncut powder bags may fall into the hopper as a whole, which is inefficient. When the powder is poured out, it is easy for the powder to splash out. If workers operate at close range for a long time, there is a risk of illness. Utility Model Content

[0005] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a powder feeding device that can automatically feed powder into a mixer, reduce the transfer frequency of powder bags, have high efficiency, and reduce workers' contact time.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] like Figures 1-4 As shown, this embodiment provides a powder feeding device for feeding materials into the hopper 11 at the top of the mixer 10. The device includes a material bag conveying component 20 and a bag opening component 30.

[0024] Specifically, such as Figure 1-Figure 2 As shown, the material bag conveying assembly 20 includes an annular conveyor belt 21, a lifting rod 22 distilled along the annular conveyor belt 21, and a hook 23 provided at the lower end of the lifting rod 22. The upper end of the lifting rod 22 is connected to the annular conveyor belt 21, so that the lifting rod 22 moves synchronously with the annular conveyor belt 21, and the hook 23 is used to hang the powder bag 1.

[0025] The bag opening assembly 30 is arranged on one side of the mixer 10 and is located opposite to the feeding direction of the endless conveyor belt 21. The bag opening assembly 30 includes a blade 31. The blade 31 is arranged with the cutting edge facing upward, and the blade 31 is moved along the radial direction of the hopper to penetrate one side of the hopper 11, and is used to cut the bottom of the powder bag 1 so that the powder can be poured into the hopper 11.

[0026] Specific operation process:

[0027] The powder bag 1 to be loaded is moved to the bottom of one end of the mixer 10 on the ring conveyor 21, and one of the lifting rods 22 is extended downward, and the hook 23 corresponding to the lower end of the lifting rod 22 is moved to the top of one of the powder bags 1. The ring conveyor 21 is paused, and the upper end of the powder bag 1 is hung along the hook 23. The ring conveyor 21 is started again, and the next lifting rod 22 is moved to the position where the previous lifting rod 22 hangs the powder bag 1, and the powder bag 1 is hung. This reciprocating process is repeated to hang multiple powder bags 1 in sequence and convey them to the direction of the hopper 11.

[0028] When the conveyed material bag 1 is located on a side of the hopper 11 away from the bag assembly 30, the corresponding lifting rod 22 is retracted upward so that the powder bag 1 at its lower end is lifted upward to the top of the hopper 11. When the powder bag 1 moves to just above the hopper 11, the lifting rod 22 moves vertically downward so that the powder bag 1 moves vertically downward into the hopper 11, and the bottom of the powder bag 1 falls into the moving track of the blade 31. The blade 31 is moved radially along the hopper 11 so that the blade 31 cuts the powder bag 1 along the bottom of the powder bag 1, thereby automatically putting the powder into the mixer 10.

[0029] Specifically, in order to prevent the powder from flying during the falling process and affecting the workshop environment, a dust cover 12 is provided on the top of the hopper 11. The dust cover 12 is annular in structure, so that the outer ring of the dust cover 12 is fixed to the top of the hopper 11, and the inner ring of the dust cover 12 is used for the powder bag 1 to pass through.

[0030] Specifically, such as Figure 3-Figure 4As shown, in order to automatically remove the powder bag 1 from the hook 23 after loading and reduce the input of the power source, a connecting rod 32 is provided at the end of the blade 31 away from the hopper 11. The connecting rod 32 has a U-shaped structure, which includes a first support arm 321 and a second support arm 322 arranged in a row and a horizontal section 323. One end of the first support arm 321 and the second support arm 322 is facing the direction of the hopper 11, and the other end of the first support arm 321 and the second support arm 322 is respectively connected to the two ends of the inner side of the horizontal section 323.

[0031] The length of the first arm 321 is greater than that of the second arm 322. The end of the first arm 321 facing the hopper 11 is connected to the blade 31, and the end of the second arm 322 facing the side where the hopper 11 is located is connected to the material removal clamp 35 for removing the empty powder bag 1. The cylinder 33 is mounted on the support 34, and the output end of the cylinder 33 is connected to the outer side surface of the cross section 323.

[0032] During use, the cylinder 33 pushes the connecting rod 32 to move toward the hopper 11, so that the first arm 321 drives the blade 31 to move along the bottom of the powder bag 1, thereby cutting the bottom of the powder bag 1; the second arm 322 drives the material clip 35 to move to the bottom of the last powder bag 1 that has finished loading, so that the corresponding lifting rod 22 moves vertically downward, and the hook 23 corresponding to the lower end of the lifting rod 22 passes through the material clip 35, so that the powder bag 1 that has finished loading is downward, and moves vertically upward under the action of the material clip 35, thereby separating from the powder bag 1.

[0033] Furthermore, in order to prevent the powder package 1 from being stuck in the material-diverting clamp 35 after the powder package 1 is loaded, an arc-shaped surface 351 is provided on the inner side of the front end of the opening of the material-diverting clamp 35 .

[0034] The above description is only a preferred embodiment of the present invention and does not represent the only embodiment or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
