[0025] Embodiment

[0026] Refer to Figures 1-4As shown in the figure, an automatic feeding device in the production of food-grade calcium carbonate includes a storage box housing 1 and a moving bracket 2 installed at the bottom of the storage box housing 1 for the movement of the storage box housing 1. There is a discharge port 311 at the bottom of the storage box housing 1. The bottom end of the moving bracket 2 is connected to a movable plate 312 through a driving mechanism. The top end of the movable plate 312 is connected to a closing plate 313 through a telescopic mechanism. A sealing layer 314 corresponding to the discharge port 311 is fixed at the top end of the closing plate 313. The telescopic mechanism can make the closing plate 313 and the sealing layer 314 rebound upward stably. The sealing layer 314 can be made of rubber material and can fully fit the bottom of the discharge port 311. Under the action of the telescopic mechanism, it can ensure that the material will not fall through the discharge port 311, avoiding the problem of material waste. Under the action of the driving mechanism, the sealing layer 314 can move back and forth, so as to adjust the opening or closing of the discharge port 311 and achieve the discharging effect.

[0027] The telescopic mechanism includes a movable column 315, a fixed cylinder 316 and a spring 317. The movable column 315 is fixed at the bottom end of the closing plate 313. The fixed cylinder 316 is fixed at the top of the movable plate 312 and sleeved on the outer wall of the movable column 315. One end of the spring 317 is connected to the movable column 315 and the other end is connected to the inner wall of the fixed cylinder 316. In the initial state, the spring 317 can be in an extended state and push the movable column 315, the closing plate 313 and the sealing layer 314 to move upward stably, and can drive the sealing layer 314 to closely fit the discharge port 311.

[0028] The driving mechanism includes a mounting plate 318, a motor 319, a lead screw 320 and a threaded sleeve 321. The mounting plate 318 is fixed at the bottom end of the moving bracket 2. The motor 319 is installed on the outer wall of the mounting plate 318 and the output end is connected to the lead screw 320. One end of the threaded sleeve 321 is fixed to the movable plate 312 and the other end is threadedly connected to the outer wall of the lead screw 320. By turning on the motor 319 to drive the rotation of the lead screw 320, under the action of the thread, the threaded sleeve 321 and the movable plate 312 are driven to move forward, and the sealing layer 314 can be separated from the discharge port 311. A guiding block 322 is fixed at the bottom end of the mounting plate 318. A guiding rod 323 passing through the guiding block 322 is fixed on the outer wall of the movable plate 312. When the movable plate 312 moves, the guiding rod 323 will move back and forth inside the guiding block 322, improving the stability of the movement of the movable plate 312. A baffle 324 is fixed at the end of the guiding rod 323 away from the movable plate 312. The diameter of the baffle 324 is larger than that of the guiding rod 323. The setting of the baffle 324 can ensure that the guiding rod 323 will not fall off the guiding block 322.

[0029] The automatic feeding device further includes a feed inlet 411 installed on the inner wall of the top end of the storage box housing 1 and a cover plate 412 arranged at the middle position of the feed inlet 411 and communicating with the inside of the storage box housing 1.

[0030] An installation bracket 413 is fixed to the outer wall of the feed inlet 411. An opening 414 is provided at the bottom end of the installation bracket 413. A fixing screw 415 corresponding to the opening 414 is fixed to the side wall of the storage box housing 1. A fastening pad 416 is sleeved on the outer wall of the fixing screw 415. A nut 417 that fits against the fastening pad 416 is threadedly connected to the outer wall of the fixing screw 415. Rotating the nut 417 can cause it to disengage from the fixing screw 415 and pull the installation bracket 413 upward to separate the feed inlet 411 from the top of the storage box housing 1, thereby facilitating a comprehensive cleaning and maintenance of the interior of the storage box housing 1.

[0031] Working principle: When discharging is required, the motor 319 is turned on to drive the lead screw 320 to rotate. Under the action of the thread, the threaded sleeve 321 and the movable plate 312 are driven to move forward. At this time, the fixed cylinder 316, the movable column 315, the closing plate 313, and the sealing layer 314 can move forward. The sealing layer 314 will disengage from the discharge port 311, causing the discharge port 311 to be in an open state. At this time, the raw materials inside the storage box housing 1 can be discharged downward through the discharge port 311. This feeding method has a smaller feeding path, reducing the problem of material waste.

[0032] When the interior of the storage box housing 1 needs to be cleaned, the nut 417 is disengaged from the fixing screw 415 by rotating the nut 417. Subsequently, pulling the installation bracket 413 upward can disassemble the feed inlet 411, facilitating a comprehensive cleaning of the interior of the storage box housing 1.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
