Specific embodiments

[0021] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0023] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0024] Example 1, refer to Figures 1 to 8, which is the first embodiment of the present invention. This embodiment provides a pet food production device with a circulating drying function, which can achieve the effect of circulating and drying pet food. It includes a support assembly 100, which includes a support frame 101. The support frame 101 provides a support effect for the entire device. There is a fixed barrel 102 arranged inside the support frame 101. The fixed barrel 102 is fixedly installed on the support frame 101. There is a first feed inlet opened on the outer wall of the fixed barrel 102 and a first discharge outlet opened on the outer wall of the fixed barrel 102. The first feed inlet and the first discharge outlet are respectively opened on the upper and lower sides of the fixed barrel 102; Furthermore, a swing assembly 200 includes a swing barrel 208 arranged inside the fixed barrel 102, a second feed inlet opened on the outer wall of the swing barrel 208, a second discharge outlet opened on the outer wall of the swing barrel 208. The second feed inlet and the second discharge outlet are respectively opened on the upper and lower sides of the swing barrel 208. There is a limit stop 204 arranged outside the swing barrel 208, a first turntable 202 arranged outside the swing barrel 208, a first cylinder 203 arranged at the end of the first turntable 202, and a heating rod 209 arranged on the inner wall of the swing barrel 208. The first cylinder 203 is fixedly installed at one end of the first turntable 202. The heating rod 209 is fixedly installed inside the swing barrel 208, and the heating rod 209 is powered through an external connecting wire; Furthermore, a rotating assembly 300 includes a rotating barrel 301 rotatably arranged between the fixed barrel 102 and the swing barrel 208 and a third discharge outlet opened on the outer wall of the rotating barrel 301. The fixed barrel 102, the rotating barrel 301, and the swing barrel 208 rotate relative to each other and are in close contact with each other's barrel walls. The rotating barrel 301 only has a third discharge outlet opened on its outer wall; Furthermore, when the third discharge outlet of the rotating barrel 301 coincides with the first feed inlet of the fixed barrel 102 and the second feed inlet of the swing barrel 208, feeding is completed. When the third discharge outlet of the rotating barrel 301 coincides with the first discharge outlet of the fixed barrel 102 and the second discharge outlet of the swing barrel 208, discharging is completed; Specifically, the rotation of the rotating barrel 301 enables the third discharge outlet to coincide with the first discharge outlet and the second discharge outlet respectively, and at the same time, the rotation of the rotating barrel 301 enables the third discharge outlet to coincide with the first feed inlet and the second feed inlet respectively; During use, rotate the first turntable 202. The rotation of the first turntable 202 drives the first cylinder 203 to perform a circular motion. When the first cylinder 203 contacts the limit stop 204, it will push the limit stop 204 to move upward. After the first turntable 202 rotates a certain angle, the first cylinder 203 will separate from the end of the limit stop 204. At this time, the first cylinder 203 no longer pushes the limit stop 204, and the limit stop 204 starts to return to its initial position to wait for the next contact with the first cylinder 203. During this process, the limit stop 204 drives the rotation of the swing barrel 208, enabling it to achieve an intermittent swing state. The swing of the swing barrel 208 drives the second feed inlet and the second discharge outlet to move together. At the same time, the intermittent rotation of the rotating barrel 301 drives the third discharge outlet to perform a circular motion. When the rotating barrel 301 rotates a certain angle, the first feed inlet, the second feed inlet, and the third discharge outlet coincide, and feeding starts. After the intermittent rotation stops, the rotating barrel 301 drives the third discharge outlet to continue rotating. Even if the first feed inlet and the second feed inlet coincide, feeding will stop due to the blocking of the rotating barrel 301. When the rotating barrel 301 rotates a certain angle again, the first discharge outlet, the second discharge outlet, and the third discharge outlet coincide, and discharging starts. After the intermittent rotation stops, the rotating barrel 301 drives the third discharge outlet to continue rotating. Even if the first discharge outlet and the second discharge outlet coincide, discharging will stop due to the blocking of the rotating barrel 301; In summary, when the feed inlet and the discharge outlet coincide, the effects of feeding and discharging the feed are achieved, enabling the feed to have a certain drying time and a certain shaking effect in the swing barrel 208, preventing the feed from piling up during drying and being unable to be heated evenly, greatly improving the drying effect, achieving the effect that the feed can be fed and discharged in batches, and realizing the function of circulating drying of the feed.

[0025] Example 2, referring to Figures 1 to 4 , is the second embodiment of the present invention. Different from the previous embodiment, this embodiment solves the problem of the swing of the swing barrel 208. It includes a support frame 101 provided on the outer wall of the fixed barrel 102. The upper and lower parts of the fixed barrel 102 are respectively provided with a feed hopper 103 and a receiving hopper 104. The feed hopper 103 is fixedly installed on the upper part of the fixed barrel 102 and is docked with the first feed inlet. The receiving hopper 104 is fixedly installed on the lower part of the fixed barrel 102 and is docked with the first discharge outlet. A support frame 106 is provided on the outer wall of the receiving hopper 104, and the support frame 106 is fixedly connected to the receiving hopper 104; Further, a servo motor 201 is provided on the outer wall of the support frame 106. The first turntable 202 is disposed at the output end of the servo motor 201, and the output end of the servo motor 201 is fixedly connected to the first turntable 202 to provide a power source for its rotation. A guide groove 206 is provided at the end of the support frame 106. A first spring 207 is provided on the inner wall of the guide groove 206, and the end of the first spring 207 is fixedly connected to the end of the inner wall of the guide groove 206; Further, a partition plate 105 is provided on the outer wall of the swing bucket 208. A slide rod 205 is provided on the outer wall of the partition plate 105, and a limit stop 204 is provided on the outer wall of the partition plate 105. The slide rod 205 is fixed to the first spring 207. The slide rod 205 slides in the guide groove 206. The slide rod 205 is slidably installed in the guide groove 206 and is fixedly connected to the first spring 207 in the guide groove 206; Further, the limit stop 204 and the first cylinder 203 are on the same horizontal plane. Both the limit stop 204 and the slide rod 205 are fixedly connected to the partition plate 105. The partition plate 105 is fixedly connected to the swing bucket 208. When the first cylinder 203 rotates, it pushes the limit stop 204. After the first cylinder 203 rotates a certain angle, it disengages from the limit stop 204; During use, driven by the servo motor 201, the first turntable 202 rotates, thereby driving the swing of the swing bucket 208. When the swing bucket 208 swings outwards, the slide rod 205 slides out of the guide groove 206 and simultaneously pulls the first spring 207 to stretch. When the first cylinder 203 rotates a certain angle and disengages from the limit stop 204, the slide rod 205 is subjected to the pulling force of the first spring 207, and the spring rebounds, and the slide rod 205 slides back into the guide groove 206; In summary, the swinging effect of the swing bucket 208 is realized, and at the same time, the problem that the swing bucket 208 may deviate in angle during swinging is solved, and the elastic force of the first spring 207 realizes the effect that the swing bucket 208 can swing multiple times.

[0026] Example 3, referring to Figures 4 to 8 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment solves the problems of rotation and timing of the feed drying device. It includes that a second turntable 305 is provided on the outside of the swing bucket 208. A dial rod 308 is provided at the end of the second turntable 305. A first ratchet wheel 309 is provided on the inner wall of the rotating bucket 301. A second ratchet wheel 312 is provided on the outside of the fixed bucket 102. A limiting ball 313 is annularly arranged on the outer wall of the second ratchet wheel 312. A first rotating rod 302 is provided on the outer wall of the swing bucket 208. A second rotating rod 303 is provided on the outer wall of the rotating bucket 301. A third rotating rod 304 is provided on the outer wall of the second rotating rod 303. The first rotating rod 302 rotates in the second rotating rod 303; The second turntable 305 is provided on the outer wall of the first rotating rod 302. The first ratchet wheel 309 is provided on the outer wall of the second rotating rod 303. A second cylinder 306 is provided at the end of the second turntable 305. A second spring 307 is provided on the outer wall of the second cylinder 306. The dial rod 308 is respectively provided on the outer walls of the second cylinder 306 and the second spring 307; Specifically, the first rotating rod 302 is fixedly connected to the end of the swinging barrel 208, the second rotating rod 303 is fixedly connected to the end of the rotating barrel 301, and the first rotating rod 302 is rotatably connected within the second rotating rod 303. The third rotating rod 304 is fixedly installed at the end of the second rotating rod 303. The second turntable 305 is fixedly connected to the outer wall of the first rotating rod 302. The first ratchet wheel 309 is fixedly connected to the outer wall of the second rotating rod 303. The second ratchet wheel 312 is fixedly connected to the outer wall of the third rotating rod 304. The second cylinder 306 is fixedly connected to the bottom end of the second turntable 305. The lever 308 is rotatably connected to the end of the second cylinder 306; Further, one end of the third rotating rod 304 is provided with a hollow disk 310. Both the second ratchet wheel 312 and the limiting ball 313 are arranged inside the hollow disk 310. The hollow disk 310 is fixedly connected to the outer wall of the fixed barrel 102; Further, one end of the third rotating rod 304 is provided with a pointer 311. A scale disk 314 is arranged on the outer wall of the hollow disk 310. The pointer 311 rotates on the outer wall of the scale disk 314. The scale disk 314 is fixedly connected to the outer wall of the hollow disk 310. The pointer 311 rotates on the outer wall of the scale disk 314; Further, the first ratchet wheel 309 and the lever 308 are on the same horizontal plane. When the lever 308 rotates with the second turntable 305, it pushes the first ratchet wheel 309. After the lever 308 rotates with the second turntable 305 by a certain angle, it disengages from the first ratchet wheel 309; During use, when the swinging barrel 208 swings, it drives the second turntable 305 on the first rotating rod 302 to rotate by a certain angle. The rotation of the second turntable 305 drives the lever 308 to move upward, causing it to push the first ratchet wheel 309 to rotate by a certain angle. When the swinging barrel 208 swings downward, the lever 308 does not push the first ratchet wheel 309, and due to the extrusion of the outer angle of the first ratchet wheel 309, the lever 308 rotates outward on the second cylinder 306, enabling the second turntable 305 to rotate downward smoothly. The rotation of the first ratchet wheel 309 drives the rotating barrel 301 connected to the second rotating rod 303 to perform intermittent rotation, achieving the effect of driving the third discharge port to displace, thereby achieving the effect of feeding and pushing materials. At the same time, as the third rotating rod 304 rotates with the second rotating rod 303, it drives the pointer 311 to rotate on the scale disk 314. At the same time, the second ratchet wheel 312 installed on the third rotating rod 304 rotates accordingly. However, due to the limitation of the limiting ball 313 on the corner of the ratchet wheel, the second ratchet wheel 312 will be locked by the limiting ball 313 after rotating back by a certain angle, preventing the third rotating rod 304 from rotating in reverse; In summary, the movement of the lever 308 drives the first ratchet wheel 309 to rotate intermittently the rotating barrel 301, enabling it to operate stably. At the same time, the cooperation between the second ratchet wheel 312 and the limit ball 313 achieves the anti-reverse rotation effect of the rotating barrel 301. The rotation of the pointer 311 on the scale 314 visualizes the time, presenting the timing effect on the scale 314, which can effectively prevent over-drying and ensure product quality.
