The conveying hose 303 at the top of the spray head 318 is connected with the storage tank 301, so that the liquid in the storage tank 301 can be sprayed into the tank body 1 through the spray head 318. Under the condition that the first bevel gear 317 is controlled to reciprocate, the entire spray head 318 can reciprocate, and the spraying path of the liquid can be reciprocated in a circular arc shape.

This can ensure that each portion of fresh food is uniformly contacted with the liquid, so that the nutritional content, flavor and humidity of the product are consistent, and the core requirement of nutritional balance of pet food is met.

[0037] With reference to Figures 1-10The embodiment also proposes that the inside of the conveying pipe 302 is internally provided with a liquid quantity adjusting mechanism 4. The liquid quantity adjusting mechanism 4 comprises a control motor 401 which is connected with the flow detector through an electric signal. When the flow detector detects different quantities of minced meat in the inside of the feeding pipe 304, the electric signal generated is also different, which further causes different rotating angles of the control motor 401. The control motor 401 is fixedly installed on the top of the tank body 1. The inside of the conveying pipe 302 is fixedly provided with an adjusting pipe 402. The pipe diameter of the adjusting pipe 402 is larger than that of the conveying pipe 302. The inside of the adjusting pipe 402 is fixedly provided with a semi-cylinder 403.

The end of the sliding cylinder 406 is provided with a cage sleeve 407. The side of the sliding cylinder 406 is fixedly provided with a first mounting seat 408. The inside of the first mounting seat 408 is rotatably provided with a connecting rod 409. The other end of the connecting rod 409 is rotatably connected with the crankshaft 405. When the flow detector detects the change of the quantity of minced meat in the inside of the feeding pipe 304, the control motor 401 drives the second rotating shaft 404 to rotate. The rotating second rotating shaft 404 can drive the crankshaft 405 to rotate, which further drives the connecting rod 409 to rotate, so as to drive the sliding cylinder 406 to slide in the inside of the semi-cylinder 403. The liquid flows out through the top of the adjusting pipe 402, and then flows through the gap between the adjusting pipe 402 and the semi-cylinder 403. Because the pipe diameter of the adjusting pipe 402 is larger than that of the conveying pipe 302, and the pipe diameter of the sliding cylinder 406 is the same as the inner diameter of the conveying pipe 302, when the sliding cylinder 406 slides to the inside of the conveying pipe 302, the liquid flowing in the inside of the conveying pipe 302 is blocked, so that the liquid cannot flow through the gap between the adjusting pipe 402 and the semi-cylinder 403. Because the front end of the sliding cylinder 406 is provided with the cage sleeve 407, when the cage sleeve 407 slides to the junction of the adjusting pipe 402 and the conveying pipe 302, the liquid can flow into the gap between the adjusting pipe 402 and the semi-cylinder 403 through the cage sleeve 407. The proportion of the cage sleeve 407 and the sliding cylinder 406 at the junction of the adjusting pipe 402 and the conveying pipe 302 can be adjusted by adjusting the rotating amplitude of the second rotating shaft 404, so as to adjust the liquid flow through the adjusting pipe 402 and the semi-cylinder 403.

[0039] Specifically, the working process or working principle of the liquid adding and mixing device for pet fresh food production is that machines for cutting fresh meat into meat paste are arranged in the factory, the feeding pipe 304 is connected with the discharge of the machines, and the meat paste is transported through the feeding pipe 304 to the inside of the mixing device and mixed with the liquid through the spiral conveying pipe, the liquid can be edible oil or liquid additive, the flow detector adopts a worm gear type flow detector, when the meat paste passes through the feeding pipe 304, the worm gear arranged inside the feeding pipe 304 rotates, the faster the worm gear rotates, the more meat paste passes through the inside of the feeding pipe 304, when the first bevel gear 317 rotates, the rotating first bevel gear 317 can drive the first rotating shaft 315 to rotate, the rotating first rotating shaft 315 can drive the connecting plate 316 to rotate, and then the second sliding block 311 can slide in the second sliding groove 310, and under the driving of the connecting plate 316, the second sliding block 311 can make circular motion around the first rotating shaft 315, and then the two first rotating plates 309 can rotate, the rotation of the two first rotating plates 309 can drive the spray head 318 to rotate, the top of the spray head 318 is connected with the storage tank 301 through the conveying hose 303, so that the liquid in the storage tank 301 can be sprayed into the inside of the tank body 1 through the spray head 318, under the control of the reciprocating rotation of the first bevel gear 317, the whole spray head 318 can reciprocate, and then the spraying path of the liquid can be reciprocated in a circular arc shape.

[0040] When the flow detector detects that the amount of minced meat in the feed pipe 304 is different, the generated electrical signal is also different, thereby causing the control motor 401 to rotate at different angles. When the flow detector detects that the amount of minced meat in the feed pipe 304 changes, the control motor 401 drives the second rotating shaft 404 to rotate, and the rotating second rotating shaft 404 can make the crankshaft 405 rotate, thereby driving the connecting rod 409 to rotate, so that the sliding cylinder 406 slides in the inside of the semi-cylinder 403. The liquid flows out through the top of the adjusting pipe 402, and then flows through the gap between the semi-cylinder 403 and the adjusting pipe 402. Because the pipe diameter of the adjusting pipe 402 is larger than the pipe diameter of the conveying pipe 302, and the pipe diameter of the sliding cylinder 406 is the same as the inner diameter of the conveying pipe 302, when the sliding cylinder 406 slides into the conveying pipe 302, it will block the liquid flowing in the conveying pipe 302, so that the liquid cannot pass through the gap between the semi-cylinder 403 and the adjusting pipe 402. Since the front end of the sliding cylinder 406 is provided with a cage sleeve 407, when the cage sleeve 407 slides to the junction of the adjusting pipe 402 and the conveying pipe 302, the liquid can flow into the gap between the semi-cylinder 403 and the adjusting pipe 402 through the cage sleeve 407. The proportion of the cage sleeve 407 and the sliding cylinder 406 at the junction of the pipe 402 and the conveying pipe 302 can be adjusted by adjusting the rotation amplitude of the second rotating shaft 404, so that the liquid flow through the semi-cylinder 403 and the adjusting pipe 402 can be adjusted. The other end of the second rotating shaft 404 penetrates to the other side of the adjusting pipe 402, and the first worm 410 is fixedly installed at the end of the second rotating shaft 404. The first mounting bracket 411 is fixedly installed at the top of the tank 1, and the first worm wheel 412 is rotatably installed in the inside of the first mounting bracket 411. The first worm 410 is engaged with the first worm wheel 412. The first threaded rod 307 penetrates to the top of the tank 1 and is rotatably connected with the tank 1. The second worm wheel 413 is fixedly installed at the top of the first threaded rod 307. The second worm 414 is fixedly installed at the bottom of the first worm wheel 412, and the second worm 414 is engaged with the second worm wheel 413. When the second rotating shaft 404 rotates, the first worm 410 can rotate, thereby driving the first worm wheel 412 to rotate. The rotation of the first worm wheel 412 can drive the second worm 414 to rotate, and the rotation of the second worm 414 can drive the second worm wheel 413 to rotate. When the second worm wheel 413 rotates, the first threaded rod 307 can rotate, and the rotation of the first threaded rod 307 can drive the first sliding block 308 to move on the surface of the mounting plate 305. In this way, the positions of the two second sliding blocks 311 in the two second sliding grooves 310 can be changed, thereby changing the rotation radius of the two first rotating plates 309. When the amount of minced meat in the feed pipe 304 increases, the swing amplitude of the spray head 318 also increases.

[0041] The top of the tank body 1 is provided with a reciprocating motor, under the driving of the reciprocating motor, the third rotating shaft 502 is reciprocated, under the driving of the third rotating shaft 502, the second bevel gear 503 is reciprocated, and then the first bevel gear 317 is reciprocated, so as to drive the spray head 318 to swing and spray. When the third rotating shaft 502 is reciprocated, the connecting rod 504 is reciprocated, so that the beating plate 505 is reciprocated, the outlet of the feeding pipe 304 is directly above the beating plate 505, when the minced meat is transported from the inside of the feeding pipe 304 to the inside of the tank body 1, the falling minced meat is scattered by the beating of the beating plate 505, so that the falling minced meat can be evenly dropped into the tank body 1. Under the driving of the third rotating shaft 502, the second rotating plate 507 is reciprocated, the reciprocation of the second rotating plate 507 can drive the third rotating plate 508 to reciprocate, so that the U-shaped frame 506 can complete the circumferential motion, similar to the working principle of a sewing machine. Under the action of the reciprocating movement of the foot pedal, the flywheel is driven to complete the circumferential motion, the circumferential motion of the U-shaped frame 506 can drive the fourth rotating shaft 509 to rotate, and then the stirring rod 512 can be driven to rotate, so as to mix the minced meat and liquid in the tank body 1. When the flow detector detects that the amount of minced meat in the feeding pipe 304 increases, the stepping motor 520 can be driven to rotate by a certain amplitude, and then the double-groove pulley at the output end of the stepping motor 520 can be driven to rotate. The rotation of the double-groove pulley can drive the pulleys at the bottoms of the two second threaded rods 513 to rotate, so as to drive the second threaded rods 513 to rotate. The rotation of the second threaded rods 513 can drive the threaded sleeves 514 to move on the surfaces of the second threaded rods 513, and then the rotation of the second threaded rods 513 can drive the rotation of the second threaded rods 513 to change the position of the second threaded rods 513. Under the driving of the rotating ring 515, the fifth rotating plate 517 is rotated, and then the stirring radius of the entire stirring rod 512 is increased.
