When the lid is opened with the prior art, the sealing buckle is manually pulled to rotate around the box body to tear off the sealing strip, and the movable block drives the two movable rods to move outward and at the same time drives the two limit plates to compress the two first return springs to move one end of the two movable rods away from the inside of the two sliding grooves, and the two movable rods move away from the inside of the positioning holes, and the second return springs on both sides drive the two movable plates to move up to open the box lid. The operation is cumbersome, labor-intensive, and inconvenient to use.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0005] In order to solve the problems of the prior art, the present invention provides a pet feeding machine, which forms an assembly line from unloading to recycling of cans through mechanical automation, and works in a cycle, replacing manual work of opening the lids of pet cans for feeding, saving labor and making it more convenient to use.

[0006] In order to achieve the above object, the technical solutions applied by the present invention are as follows:

[0007] A pet feeder comprises a shell, which is provided with a feeding port, a silo, a waste storage bin and a conveying assembly arranged inside the shell, the silo containing cans, and a can discharge port provided on the silo; when the conveying assembly rotates forward, it is used to convey cans dropped from the can discharge port to the feeding port, and to open the lids of the cans located at the feeding port through a lid opening device; when the conveying assembly rotates reversely, it is used to convey empty cans in the feeding port to the waste storage bin. With this arrangement, when unloading, the cans are unloaded into the conveying assembly through the can unloading port, and the conveying assembly rotates forward to drive the cans to the feeding port, and the cans are opened by the lid opening device, which is convenient for feeding pets. When the cans are empty, the conveying assembly rotates reversely to convey the empty cans in the feeding port to the waste storage bin, while avoiding space for the next can to the feeding port. The present invention forms an assembly line from unloading to recycling of cans through mechanical automation, and works in a cycle, replacing manual work to open the lids of pet cans for feeding, saving labor and being more convenient to use.

[0008] According to the above solution, an inclined guide rail is fixed to the inner wall of the housing, with the higher end of the guide rail located below the can discharge port and the lower end of the guide rail located above the conveyor assembly. A recovery channel is formed between the lower end of the guide rail and the conveyor assembly, and the recovery channel is connected to the waste storage bin. In this arrangement, during can discharge, the guide rail guides cans that fall through the can discharge port to the conveyor assembly, which rotates forward to transport the cans to the feed port. During recovery, the conveyor assembly rotates backward to transport empty cans through the recovery channel and into the waste storage bin.

[0009] According to the above scheme, the can includes a flip cover and a box body, the first end of the flip cover is hinged to the first end of the box body, and the second end of the flip cover is correspondingly locked to the second end of the box body through a locking assembly; the cover opening device includes an unlocking assembly and a driving assembly. When the conveying assembly conveys the can falling from the can feeding port to the feeding port, the unlocking assembly unlocks the locking assembly, and then the driving assembly drives the unlocked flip cover to flip open relative to the box body.

[0010] According to the above scheme, the locking assembly includes a lock buckle provided on the flip cover and a lock groove provided on the box body, and the lock buckle is locked correspondingly to the lock groove; the unlocking assembly includes a first unlocking protrusion, the first unlocking protrusion is located outside the feeding port, and a second unlocking protrusion is provided on the flip cover. When the conveying assembly conveys the can dropped from the can feeding port into the feeding port, the second unlocking protrusion is pushed upward by the first unlocking protrusion, so that the second unlocking protrusion drives the lock buckle to move upward and disengage from the lock groove. In this way, when the conveying assembly conveys the can dropped from the can feeding port into the feeding port, the conveying force of the conveying assembly drives the can to move toward the first unlocking protrusion, so that the second unlocking protrusion contacts the first unlocking protrusion, and under the continuous force, the second unlocking protrusion and the first unlocking protrusion are driven to form an extrusion, so that the second unlocking protrusion is pushed upward by the first unlocking protrusion, and when the second unlocking protrusion moves upward, it drives the lock buckle to disengage from the lock groove.

[0011] According to the above solution, a first limiting strip is provided on the inner wall of the feeding port, and a second limiting strip is provided on the outer wall of the box body. When the conveying assembly conveys the cans dropped from the can feeding port into the feeding port, the second limiting strip cooperates with the first limiting strip to limit the position of the box body. With this arrangement, when the conveying assembly conveys the cans dropped from the can feeding port into the feeding port, the first limiting strip and the second limiting strip cooperate to limit the longitudinal direction of the box body, so that when the flip cover moves upward, the box body does not move upward with it, thereby achieving unlocking.

[0012] According to the above solution, a trigger assembly is provided within the feed port. When the conveyor assembly delivers a can from the can discharge port to the feed port and unlocks it, the can triggers the trigger assembly, activating the drive assembly, which drives the unlocked flap to flip open relative to the can body. In this arrangement, in the initial state, the drive assembly is away from the can, facilitating movement of the can on the conveyor assembly. When the can is unlocked, it triggers the trigger assembly, causing the drive assembly to begin operating.

[0013] According to the above scheme, a rotating shaft is fixed to the first end of the flip cover, and the rotating shaft is hinged to the first end of the box body. When the conveying component conveys the can box that falls from the can box feeding port to the feeding port for unlocking, the driving component is correspondingly connected to the rotating shaft, and drives the rotating shaft to drive the unlocked flip cover to flip open relative to the box body.

[0014] According to the above scheme, the driving assembly includes a second motor and a third motor, the second motor is fixed in the shell, and a push rod is fixed to the output end of the second motor, and the push rod is correspondingly arranged to the third motor. The third motor is slidably arranged on the outer wall of the transmission assembly, and a rotating rod is fixed to the output end of the third motor, and the rotating rod is correspondingly connected to the rotating shaft. When the transmission assembly transfers the can box falling from the can box feeding port to the feeding port for unlocking, the second motor drives the push rod to extend and push the third motor close to the can box, so that the rotating rod is locked and connected with the rotating shaft, and the third motor drives the rotating rod to drive the rotating shaft to rotate, so that the rotating shaft drives the unlocked flip cover to flip open relative to the box body.

[0015] According to the above solution, a guide slide is fixed to the outer wall of the conveyor assembly, and a third motor is slidably connected to the guide slide. A return spring is provided between the third motor and the outer wall of the conveyor assembly. When the second motor drives the push rod to retract, the return spring drives the third motor away from the can, thereby disengaging the rotating rod from the rotating shaft. With this arrangement, the third motor is slidably mounted on the guide slide, so that when the third motor moves relative to the can, it moves linearly, always remaining on the same plane, thereby ensuring that the rotating rod and the rotating shaft are aligned. In an initial state, the third motor is away from the conveyor assembly under the elastic force of the return spring. When the second motor drives the third motor to slide toward the conveyor assembly, the return spring is compressed. When the rotating rod is disengaged from the rotating shaft, the conveyor assembly can rotate in the opposite direction to transport the empty can to the waste storage bin.

[0016] According to the above solution, the conveyor assembly includes a belt housing, a transmission belt, and a fourth motor. The transmission belt is mounted within the belt housing, and the fourth motor is mounted on the outer wall of the belt housing. The fourth motor is configured to drive the transmission belt in forward and reverse rotation. The first end of the transmission belt is positioned below the lower end of the guide rail and spaced vertically from the guide rail. The second end of the transmission belt is positioned within the feed port. With this arrangement, the fourth motor drives the transmission belt in forward and reverse rotation, causing the transmission belt to transport cans to the feed port or from the feed port to the waste storage bin.

[0017] According to the above solution, a pressure sensor is installed within the feed port to detect whether the cans are empty. When the pressure sensor detects that the cans are empty, the fourth motor drives the drive belt to rotate in the opposite direction, transferring the empty cans from the feed port through the recycling channel and into the waste storage bin. With this arrangement, when the pressure sensor detects that the cans are not empty, the feed state is in progress. When the pressure sensor detects that the cans are empty, the next can is required. The pressure sensor sends a signal back to the controller, which in turn sends a reverse operation signal to the fourth motor.

[0018] According to the above solution, a retaining plate is movably provided within the can discharge port, and a first motor is fixed to the hopper. The first motor is used to drive the retaining plate to rotate to open or close the can discharge port. In this arrangement, the retaining plate is driven by the first motor to open or close the can discharge port. When closed, the cans are located within the hopper, and when opened, the cans located within the hopper begin to be discharged.

[0019] Beneficial effects of the present invention:

[0020] The present invention is configured such that, during unloading, the cans are unloaded onto the conveying assembly through the can unloading port, the conveying assembly rotates forward to drive the cans to be conveyed into the feeding port, and the cans are opened by the lid opening device, which is convenient for feeding pets. When the cans are empty, the conveying assembly rotates reversely to convey the empty cans in the feeding port to the waste storage bin, while making room for the next can to enter the feeding port. The present invention forms an assembly line from unloading to recycling of cans through mechanical automation, and works in a cycle, replacing manual work to open the lids of pet cans for feeding, saving labor and being more convenient to use.

[0047] The technical solution of the present invention is described below with reference to the accompanying drawings and embodiments. Example

[0048] like Figures 1 to 21 As shown, the pet feeder described in the present invention includes a shell 1, a feeding port 11 is provided on the shell 1, a silo 2, a waste storage bin 17 and a conveying assembly are provided in the shell 1, the silo 2 is filled with cans 7, and the silo 2 is provided with a can discharge port 22; when the conveying assembly rotates forward, it is used to convey the cans 7 falling from the can discharge port 22 to the feeding port 11, and open the cans 7 located at the feeding port 11 through the cover opening device; when the conveying assembly rotates reversely, it is used to convey the empty cans 7 in the feeding port 11 to the waste storage bin 17.

[0049] With this arrangement, during operation, the cans 7 are unloaded onto the conveying assembly through the can unloading port 22, and the conveying assembly rotates forward to drive the cans 7 to be conveyed to the feeding port 11, and the cans 7 are opened by the lid opening device, which is convenient for feeding pets. When the cans 7 are empty, the conveying assembly rotates reversely to convey the empty cans 7 in the feeding port 11 to the waste storage bin 17, while avoiding the space for the next can 7 to the feeding port 11. The present invention forms an assembly line from unloading to recycling of the cans 7 through mechanical automation, and works in a cycle, replacing manual work to open the cans for feeding pets, saving labor and being more convenient to use.

[0050] In actual application, the shell 1 includes an upper cover 3, a movable cover 4 and a base 10, wherein the base 10 is installed on the bottom of the shell 1. When a certain number of cans 7 are stored, the base 10 can be opened for emptying; the upper cover 3 is installed on the top opening of the shell 1 to facilitate filling the cans 7 into the silo 2; the movable cover 4 is hinged on the feeding port 11 to open or close the feeding port 11. In the initial state, the movable cover 4 is in the state of closing the feeding port 11 to prevent foreign matter from entering the shell 1 through the feeding port 11. When the opening device opens the can 7 located at the feeding port 11, the flip cover 72 of the can 7 drives the movable cover 4 to open the feeding port 11.

[0051] Furthermore, an inclined guide rail 15 is fixed on the inner wall of the shell 1, the higher end of the guide rail 15 is located below the can discharge port 22, and the lower end of the guide rail 15 is located above the conveying assembly, and a recovery channel 16 is formed between the lower end of the guide rail 15 and the conveying assembly, and the recovery channel 16 is connected to the waste storage bin 17.

[0052] With this arrangement, during unloading, the cans 7 falling through the can unloading port 22 are guided to the conveying assembly by the guide rail 15. The conveying assembly rotates forward to convey the cans 7 to the feeding port 11. During recycling, the conveying assembly rotates backward to convey the empty cans 7 through the recycling channel 16 and fall into the waste storage bin 17.

[0053] In actual application, a limiting member is further provided on the guide rail 15 or on the inner wall of the shell 1 to cooperate with the can box 7 to limit the position, so that the can box 7 will not be thrown out of the guide rail 15 when sliding down the guide rail 15, and the can box 7 will fall exactly on the conveying assembly when sliding down the guide rail 15.

[0054] Preferably, a plurality of rollers are provided on the guide rail 15 so that the can 7 can slide down the guide rail 15 more smoothly with less damping force.

[0055] Furthermore, the can 7 includes a flip cover 72 and a box body 73, a first end of the flip cover 72 is hinged to a first end of the box body 73, and a second end of the flip cover 72 is correspondingly locked to a second end of the box body 73 by a locking assembly; the cover opening device includes an unlocking assembly and a driving assembly. When the conveying assembly conveys the can 7 dropped from the can discharge port 22 to the feeding port 11, the unlocking assembly unlocks the locking assembly, and then the driving assembly drives the unlocked flip cover 72 to flip open relative to the box body 73.

[0056] Furthermore, the locking assembly includes a lock buckle 77 provided on the flip cover 72 and a lock groove 76 provided on the box body 73, and the lock buckle 77 is locked corresponding to the lock groove 76; the unlocking assembly includes a first unlocking protrusion 13, the first unlocking protrusion 13 is located outside the feeding port 11, and a second unlocking protrusion 75 is provided on the flip cover 72. When the conveying assembly conveys the can 7 falling from the can discharge port 22 to the feeding port 11, the second unlocking protrusion 75 is pushed upward by the first unlocking protrusion 13, so that the second unlocking protrusion 75 drives the lock buckle 77 to move upward and disengage from the lock groove 76.

[0057] In this way, when the conveying component conveys the can 7 dropped from the can discharge port 22 to the feeding port 11, the conveying force of the conveying component drives the can 7 to move toward the first unlocking protrusion 13, so that the second unlocking protrusion 75 contacts the first unlocking protrusion 13, and under continuous force, the second unlocking protrusion 75 and the first unlocking protrusion 13 are driven to form an extrusion, so that the second unlocking protrusion 75 is pushed upward by the first unlocking protrusion 13, and when the second unlocking protrusion 75 moves upward, it drives the lock buckle 77 to disengage from the lock groove 76.

[0058] In actual application, the top of the first unlocking protrusion 13 is an arc surface or an inclined surface, and the bottom of the second unlocking protrusion 75 is an arc surface or an inclined surface, so that after the second unlocking protrusion 75 contacts the first unlocking protrusion 13, the bottom of the second unlocking protrusion 75 slides relative to the top of the first unlocking protrusion 13 under the action of force. When the bottom of the second unlocking protrusion 75 is located at the top of the first unlocking protrusion 13, the lock buckle 77 disengages from the lock groove 76.

[0059] Furthermore, a first limiting strip 14 is provided on the inner wall of the feeding port 11, and a second limiting strip 74 is provided on the outer wall of the box body 73. When the conveying assembly conveys the cans 7 dropped from the can discharge port 22 into the feeding port 11, the second limiting strip 74 cooperates with the first limiting strip 14 to limit the box body 73.

[0060] With this arrangement, when the conveying assembly conveys the can 7 dropped from the can discharge port 22 to the feeding port 11, the first limit bar 14 and the second limit bar 74 cooperate to form a limit on the longitudinal direction of the box body 73, so that when the flip cover 72 moves upward, the box body 73 will not move upward with it, thereby achieving unlocking.

[0061] In actual application, when the conveying assembly conveys the can 7 into the feeding port 11 , the first limiting bar 14 is located above the second limiting bar 74 , thereby limiting the second limiting bar 74 in the longitudinal direction.

[0062] Furthermore, a trigger assembly 12 is provided in the feeding port 11. When the conveying assembly conveys the can 7 dropped from the can discharge port 22 to the feeding port 11 and is unlocked, the can 7 triggers the trigger assembly 12 to activate the driving assembly, thereby driving the unlocked flip cover 72 to flip open relative to the box body 73.

[0063] With this arrangement, in the initial state, the driving assembly is away from the can 7, which facilitates the can 7 to move on the conveying assembly. When the can 7 is unlocked and triggered by the trigger assembly 12, the driving assembly starts to work.

[0064] In actual application, the position of the trigger component 12 is the unlocking position of the can 7. The trigger component 12 can be a sensor or a micro switch. When the trigger component 12 is triggered, the signal is fed back to the controller, and the controller then sends a working signal to the drive component.

[0065] Furthermore, a rotating shaft 71 is fixed to the first end of the flip cover 72, and the rotating shaft 71 is hinged to the first end of the box body 73. When the conveying assembly conveys the can 7 dropped from the can discharge port 22 to the feeding port 11 for unlocking, the driving assembly is correspondingly connected to the rotating shaft 71, and drives the rotating shaft 71 to drive the unlocked flip cover 72 to flip open relative to the box body 73.

[0066] Furthermore, the driving assembly includes a second motor 5 and a third motor 6. The second motor 5 is fixed in the shell 1. A push rod 51 is fixed to the output end of the second motor 5. The push rod 51 is correspondingly arranged with the third motor 6. The third motor 6 is slidably arranged on the outer wall of the conveying assembly. A rotating rod 61 is fixed to the output end of the third motor 6. The rotating rod 61 is correspondingly connected with the rotating shaft 71. When the conveying assembly conveys the can box 7 falling from the can box discharge port 22 to the feeding port 11 for unlocking, the second motor 5 drives the push rod 51 to extend and push the third motor 6 close to the can box 7, so that the rotating rod 61 is engaged with the rotating shaft 71. The third motor 6 drives the rotating rod 61 to drive the rotating shaft 71 to rotate, so that the rotating shaft 71 drives the unlocked flip cover 72 to flip open relative to the box body 73.

[0067] Furthermore, a guide slide 82 is fixed on the outer wall of the conveying assembly, and the third motor 6 is slidably connected to the guide slide 82. A return spring 62 is provided between the third motor 6 and the outer wall of the conveying assembly. When the second motor 5 drives the push rod 51 to retract, the return spring 62 drives the third motor 6 away from the can 7 to disengage the rotating rod 61 from the rotating shaft 71.

[0068] In this arrangement, the third motor 6 is slidably arranged on the guide slide bar 82, so that the third motor 6 moves in a straight line relative to the can box 7 and always remains on the same plane, thereby ensuring that the rotating rod 61 and the rotating shaft 71 are correspondingly positioned. In the initial state, the third motor 6 is away from the transmission assembly under the elastic force of the reset spring 62. When the second motor 5 drives the third motor 6 to slide toward the transmission assembly, the reset spring 62 is in a compressed state. When the rotating rod 61 is disengaged from the rotating shaft 71, the transmission assembly can rotate in the opposite direction to drive the empty can box 7 to be transmitted to the waste storage bin 17.

[0069] Furthermore, the transmission assembly includes a belt housing 81, a transmission belt 8 and a fourth motor 9. The transmission belt 8 is installed in the belt housing 81, and the fourth motor 9 is installed on the outer wall of the belt housing 81. The fourth motor 9 is used to drive the transmission belt 8 to rotate forward and reverse. The first end of the transmission belt 8 is located below the lower end of the guide rail 15, and is arranged at an upper and lower intervals with the guide rail 15. The second end of the transmission belt 8 is located in the feeding port 11.

[0070] With this arrangement, the fourth motor 9 drives the transmission belt 8 to rotate forward and reverse, so that the transmission belt 8 drives the cans 7 to be conveyed into the feeding port 11 or conveyed from the feeding port 11 to the waste storage bin 17 .

[0071] In actual application, the transmission belt 8 and the bottom of the can 7 are provided with cooperating locking teeth, so that when the transmission belt 8 is transmitted to the feeding port 11, a thrust is applied to the can 7 to prevent the transmission belt 8 and the can 7 from sliding relative to each other.

[0072] Furthermore, a pressure sensor is provided in the feeding port 11 for detecting whether the can 7 is empty. When the pressure sensor detects that the can 7 is empty, the fourth motor 9 drives the transmission belt 8 to rotate in the opposite direction, so as to transfer the empty can 7 from the feeding port 11 through the recovery channel 16 and drop it into the waste storage bin 17.

[0073] In this arrangement, when the pressure sensor detects that the can 7 is not empty, it is in the feeding state. When the pressure sensor detects that the can 7 is empty, the next can 7 needs to be replaced. The pressure sensor feeds back the signal to the controller, and the controller then sends a reverse working signal to the fourth motor 9.

[0074] In actual application, when unloading, when the can 7 falls on the transmission belt 8, the sensor also detects that the can 7 is fully loaded. The sensor feeds back the signal to the controller, and the controller then sends a forward working signal to the fourth motor 9.

[0075] Furthermore, a baffle plate 23 is movably provided in the can discharge port 22 , and a first motor 21 is fixed to the hopper 2 . The first motor 21 is used to drive the baffle plate 23 to rotate so as to open or close the can discharge port 22 .

[0076] With this arrangement, the first motor 21 drives the baffle plate 23 to open or close the can box discharge port 22. When closed, the can box 7 is located in the silo 2. When opened, the can box 7 in the silo 2 starts to be discharged.

[0077] In actual application, the silo 2 is loaded with a plurality of stacked cans 7. When the first motor 21 drives the baffle plate 23 to move, the plurality of cans 7 move downward synchronously until all cans 7 are emptied.

[0078] It should be noted that the lid opening device of the present invention is also provided with a controller for sending working signals to each component, wherein the controller can be remotely controlled, that is, when the owner is out, the work can still be controlled by remotely setting the program, which is more convenient to use.

[0079] Working principle of the present invention:

[0080] When unloading, the first motor 21 receives a signal, and the first motor 21 drives the baffle plate 23 to open the can unloading port 22, so that the cans 7 at the bottom layer of the silo 2 can be unloaded onto the guide rail 15. Figure 7 As shown in position a, due to the inclined setting of the guide rail 15, the can 7 slides down from position a onto the transmission belt 8, as shown in FIG. Figure 7 At position b, the fourth motor 9 receives the signal and drives the transmission belt 8 to rotate forward, driving the can 7 from the position Figure 7 The position b shown is transmitted to Figure 7 As shown in position c, the can 7 is pushed by the transmission belt 8 and moves to the unlocking position. Figure 11 When the cam 72 is unlocked, the second motor 5 drives the push rod 51 to extend and push the third motor 6 to approach the can 7, so that the rotating rod 61 is connected with the rotating shaft 71. The third motor 6 drives the rotating rod 61 to drive the rotating shaft 71 to rotate, so that the rotating shaft 71 drives the unlocked flip cover 72 to flip open relative to the box body 73. When the pressure sensor senses that the can 7 is empty, the fourth motor 9 receives a signal and drives the transmission belt 8 to rotate in the opposite direction to drive the can 7 from the feeding port 11 to the recycling channel 16 and fall into the waste storage bin 17. The next can 7 starts to be unloaded, and the cycle continues.

[0081] In the first embodiment, the silo 2 is fixed in the housing 1 . When filling cans 7 , the upper cover 3 is opened and multiple cans 7 are sequentially placed into the silo 2 . Example
