[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] The utility model discloses a feeding device for a salt bagging machine, and its structure is as shown in the attached figure. Figure 1 and attached Figure 2 As shown, it includes: a hopper 1, a stirring component 2 and a quantitative component 3.

[0029] Specifically, the quantitative assembly 3 includes a cylinder 31 , a round roller 32 and a driving mechanism 33 .

[0030] The cylinder 31 is horizontally arranged, and has a cavity corresponding to the round roller 32 inside, and a feed port 311 and a discharge port 312 connected to the cavity are respectively arranged on the upper and lower sides. The round roller 32 is rotatably arranged in the cavity of the cylinder 31, and its side wall is in contact with the inner wall of the cavity, and two quantitative grooves 321 with horizontal projection shapes overlapping the horizontal projection shape of the feed port 311 are symmetrically opened on the side wall of the round roller 32. The driving mechanism 33 is connected to the round roller 32 to drive the round roller 32 to rotate. In this embodiment, the driving mechanism 33 is a motor.

[0031] When the quantitative groove 321 is located at the top and bottom of the round roller 32 , the side wall of the round roller 32 fits with the inner wall of the cylinder 31 , so that quantitative batch feeding is achieved through the rotation of the round roller 32 .

[0032] The outlet of the hopper 1 is connected to the feed port 311 , and a screen 4 is provided at the outlet.

[0033] The stirring assembly 2 is used to stir the salt, so as to disperse the salt lumps in the salt. The stirring assembly 2 includes a rotating shaft 21, a stirring blade 22 and a power mechanism 23. In this embodiment, the power mechanism 23 is a stepping motor.

[0034] The rotating shaft 21 is rotatably disposed in the hopper 1. The stirring blades 22 are fixed at different heights of the rotating shaft 21 in at least two layers, and the stirring blades of two adjacent layers are arranged alternately. The power mechanism 23 is connected to the rotating shaft 21 in a transmission manner to drive the rotating shaft 21 to rotate. Thus, the materials at different depths are fully stirred, greatly improving the dispersion efficiency.

[0035] In this embodiment, the phase difference between the stirring blades of two adjacent layers is 45°. It is understandable that those skilled in the art can design a suitable phase difference according to actual stirring needs, such as 60° or 90°, so as to make the salt more fully dispersed, and this embodiment is not limited thereto.

[0036] In some embodiments, the stirring assembly 2 further includes a cleaning scraper 24. The cleaning scraper 24 is connected to the rotating shaft 21 and fits the surface of the screen 4. The cleaning scraper 24 is driven to rotate by the rotating shaft 21 to clean the screen 4, which can prevent the screen 4 from being blocked and facilitate the feeding of salt.

[0037] In this embodiment, the cleaning scraper 24 is a rubber plate, but this embodiment is not limited thereto.

[0038] As a specific implementation of the above embodiment, the discharge port 312 is designed to be a structure that is wide at the top and narrow at the bottom, so as to facilitate the salt to fall into the bag.

[0039] The working principle and beneficial effects of the embodiment of the utility model are:

[0040] The salt falls into the hopper 1 through the inlet of the hopper 1, and the rotating shaft 21 is driven to rotate by the power mechanism 23, thereby driving the stirring blade 22 to stir and disperse the salt, so that the salt blocks in the salt are dispersed; the dispersed salt is screened by the screen 4, and the larger salt continues to be dispersed in the hopper 1, while the normal salt falls into the quantitative groove 321 of the round roller 32, so that the quantitative batch feeding is realized through the rotation of the round roller 32, which is conducive to achieving packaging uniformity and improving the packaging quality of the salt; at the same time, the cleaning scraper 24 rotates with the rotating shaft 21 to realize the cleaning of the screen 4, which can prevent the screen 4 from being blocked and facilitate the discharge of salt.

[0041] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
