Description

Technical Field

[0001] This invention relates to the field of pet feeder technology, specifically to a can feeding assembly and a pet feeder. Background Technology

[0002] With the increasing number of pets, dry food feeders can no longer meet market demand. Wet food canned food is a combination of fresh and nutritious dry and wet options, such as canned beef or chicken. Currently, most pet feeders on the market require manual operation to dispense the food, which is inconvenient.

[0003] The invention patent disclosed in CN119791005A discloses a pet feeder, which includes a feed hopper vertically installed in the housing, containing canned food boxes. The feed hopper has a flip-top at the outlet. When feeding, the flip-top is driven by a drive component to close the outlet of the feed hopper, and then the canned food boxes are manually stacked into the feed hopper from bottom to top. When discharging, the flip-top is driven by a drive component to open the outlet of the feed hopper, and the canned food boxes are discharged through the outlet of the feed hopper under their own weight. This prior art has a relatively complex structure, and it is difficult to control the number of canned food boxes discharged during discharging.

[0004] Therefore, there is still room for improvement and development in existing technologies. Summary of the Invention

[0005] To address the problems of existing technologies, this invention proposes a can feeding and unloading assembly and a pet feeder. During feeding, cans are placed side by side into the can receiving cavity. During unloading, the cans are pushed to the can discharge port by a can pushing device. The structure is simple, and the amount of cans fed cans can be controlled by controlling the working stroke of the can pushing device, making it convenient to use.

[0006] To achieve the above objectives, the technical solution applied in this invention is as follows: A can loading and unloading assembly includes a cylinder with a can receiving cavity formed inside for loading cans. One end of the can receiving cavity has a can outlet, and the other end has a can pushing device for pushing the cans to the can outlet. This arrangement allows for loading by placing cans side-by-side into the can receiving cavity, and unloading by pushing the cans to the can outlet. It has a simple structure, and the number of cans unloaded can be controlled by adjusting the stroke of the can pushing device, making it convenient to use.

[0007] According to the above scheme, the can receiving cavity is arranged horizontally inside the material cylinder, and the position of the end with the can outlet is not higher than the position of the end with the can pushing device. The can pushing device includes a pushing block and a driving assembly. The pushing block is located inside the can receiving cavity and is driven to move by the driving assembly. A transmission assembly is provided between the pushing block and the driving assembly. With this configuration, during feeding, the driving assembly drives the pushing block to move, and the pushing block then pushes the can to the can outlet for feeding.

[0008] According to the above scheme, the transmission assembly includes a screw, a connector, and a nut. The screw is rotatably mounted on the barrel, the nut is threadedly connected to the screw, the connector is fixedly connected to the nut, and the pusher block is fixedly connected to the connector. The screw is driven to rotate by a drive assembly. With this configuration, during material discharge, the drive assembly drives the screw to rotate, causing the screw and nut to move threadedly. The nut causes the connector to move, the connector causes the pusher block to move, and the pusher block then pushes the can to the can outlet for discharge.

[0009] According to the above scheme, the drive assembly includes a driven gear, a driving gear, and a reduction motor. The reduction motor is fixed to the material cylinder by a fixed bracket. The output end of the reduction motor is fixedly connected to the driving gear. The driving gear meshes with the driven gear, and the driven gear is fixedly connected to the screw. With this configuration, during material feeding, the reduction motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, and the driven gear drives the screw to rotate.

[0010] According to the above scheme, the screw is located outside the can receiving cavity, and a sliding groove is provided on the inner wall of the can receiving cavity. One end of the connector is fixedly connected to the nut, and the other end of the connector passes through the sliding groove and is fixedly connected to the pusher block. The connector is slidably arranged with respect to the sliding groove. With this arrangement, when the screw and nut undergo threaded movement, the nut drives the connector to move relative to the sliding groove under the action of the sliding groove, preventing the connector from rotating. Furthermore, placing the screw outside the can receiving cavity makes reasonable use of the installation space and does not occupy the space of the can receiving cavity.

[0011] According to the above scheme, limit switches are fixed on the barrels at both ends of the screw, and the connecting parts are set accordingly to the limit switches.

[0012] According to the above scheme, a receiving groove is provided at the can outlet position, and a can-limiting component is provided inside the receiving groove. The can-limiting component includes a spring and a snap fastener. One end of the spring abuts against the inner wall of the receiving groove, and the other end of the spring abuts against the snap fastener. One end of the snap fastener protrudes from the receiving groove and is located inside the can-receiving cavity. An inclined end face corresponding to the can is formed on the snap fastener. This design allows the snap fastener to prevent the can from falling out, thereby limiting the position of the can.

[0013] According to the above scheme, the can outlet is connected to a guide bracket, which in turn is connected to a discharge bracket. The discharge bracket has a can discharge port, and a can discharge channel is formed between the can outlet and the can discharge port. With this configuration, the canned food is discharged through the can outlet and then through the can discharge channel, which in turn completes the discharge at the can discharge port. The can discharge channel serves to guide and buffer the food.

[0014] According to the above scheme, the feeding support is equipped with a can sensing component.

[0015] The pet feeder of the present invention includes the above-mentioned can feeding and dispensing assembly.

[0016] Beneficial effects of this invention: The present invention is designed such that, during feeding, the cans are placed side by side into the can receiving cavity, and during unloading, the cans are pushed to the can discharge port by the can pushing device. Its structure is simple, and the number of cans unloaded can be controlled by controlling the working stroke of the can pushing device, making it convenient to use. Attached Figure Description

[0019] The technical solution of the present invention will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 8 As shown, the present invention provides a can loading and unloading assembly, including a material cylinder 3, wherein a can receiving cavity 22 for loading cans 1 is formed inside the material cylinder 3; one end of the can receiving cavity 22 is provided with a can outlet 25, and the other end of the can receiving cavity 22 is provided with a can pushing device for pushing cans 1 to the can outlet 25. With this configuration, during loading, cans 1 are placed side-by-side into the can receiving cavity 22; during unloading, the can pushing device pushes the cans 1 to the can outlet 25 for unloading. Its structure is simple, and the quantity of cans 1 unloaded can be controlled by controlling the working stroke of the can pushing device, making it convenient to use.

[0021] Preferably, the canning cavity 22 can hold cans 1 of different sizes, such as 85 grams, 90 grams, 200 grams, etc.

[0022] Furthermore, the can receiving cavity 22 is horizontally arranged within the material cylinder 3, and the end with the can outlet 25 is not higher than the end with the can pushing device. The can pushing device includes a pushing block 15 and a driving assembly. The pushing block 15 is located within the can receiving cavity 22 and is driven to move by the driving assembly. A transmission assembly is provided between the pushing block 15 and the driving assembly. With this configuration, during material feeding, the driving assembly drives the pushing block 15 to move, and the pushing block 15 then pushes the can 1 to the can outlet 25 for feeding.

[0023] In the prior art, the hopper is vertically arranged, which requires a large space for the whole machine. Moreover, the center of gravity of the loaded cans directly acts on the flap at the discharge port, which will affect the working performance of the flap after a long time, thus affecting the material feeding effect. In contrast, the can receiving cavity 22 of the present invention is horizontally arranged, which can reduce the space occupied by the whole machine. The center of gravity of the loaded cans 1 directly acts on the inner wall of the material cylinder 3, eliminating the need for a flap at the can discharge port 25, resulting in a simpler structure.

[0024] The amount of canned food 1 fed can be controlled by controlling the stroke of the pusher block 15.

[0025] Furthermore, the transmission assembly includes a screw 8, a connector 14, and a nut 16. The screw 8 is rotatably mounted on the material cylinder 3. The nut 16 is threadedly connected to the screw 8, the connector 14 is fixedly connected to the nut 16, and the pusher block 15 is fixedly connected to the connector 14. The screw 8 is driven to rotate by a drive assembly. With this configuration, during material feeding, the drive assembly drives the screw 8 to rotate, causing the screw 8 and nut 16 to undergo threaded movement. The nut 16 drives the connector 14 to move, the connector 14 drives the pusher block 15 to move, and the pusher block 15 then pushes the can 1 to the can outlet 25 for feeding.

[0026] The screw 8 is fitted with movable copper sleeves 7 at both ends. The copper sleeves 7 are fixed on the barrel 3 to prevent the screw 8 from contacting and wearing with the barrel 3 when it rotates.

[0027] Furthermore, the drive assembly includes a driven gear 17, a driving gear 20, and a reduction motor 21. The reduction motor 21 is fixed to the material cylinder 3 via a fixed bracket 18. The output end of the reduction motor 21 is fixedly connected to the driving gear 20. The driving gear 20 meshes with the driven gear 17, and the driven gear 17 is fixedly connected to the screw 8. With this configuration, during material feeding, the reduction motor 21 drives the driving gear 20 to rotate, the driving gear 20 drives the driven gear 17 to rotate, and the driven gear 17 drives the screw 8 to rotate.

[0028] The displacement of the pusher block 15 can be controlled by controlling the number of rotations of the gear or screw.

[0029] Furthermore, the screw 8 is located outside the can receiving cavity 22. A groove 24 is provided on the inner wall of the can receiving cavity 22. One end of the connector 14 is fixedly connected to the nut 16, and the other end of the connector 14 passes through the groove 24 and is fixedly connected to the pusher block 15. The connector 14 and the groove 24 are slidably arranged. With this arrangement, when the screw 8 and nut 16 undergo threaded movement, the nut 16, under the action of the groove 24, causes the connector 14 to shift relative to the groove 24, preventing the connector 14 from rotating. Moreover, placing the screw 8 outside the can receiving cavity 22 makes reasonable use of the installation space and does not occupy the space of the can receiving cavity 22.

[0030] Furthermore, limit switches 4 are fixed on the barrels 3 at both ends of the screw 8, and the connecting piece 14 is correspondingly arranged with the limit switches 4.

[0031] Among them, the limit switch 4 located near the drive component is the starting switch, and the limit switch 4 located near the can outlet 25 is the ending switch. Initially, the connector 14 is in contact with the starting switch. When the connector 14 moves to contact the ending switch, the can 1 in the can receiving cavity 22 is discharged. The drive component reverses and drives the connector 14 back to the initial position. It stops after contacting the starting switch, which facilitates replenishment.

[0032] It should be noted that the canned food pushing device described in this invention can also be other structures, such as a cylinder or hydraulic cylinder that can control the position to drive the pushing block 15 to move, so as to achieve precise feeding.

[0033] Furthermore, a receiving groove is provided at the can outlet 25, and a can-limiting component is provided within the receiving groove. The can-limiting component includes a spring clip 5 and a spring 6. One end of the spring 6 abuts against the inner wall of the receiving groove, and the other end of the spring 6 abuts against the spring clip 5. One end of the spring clip 5 extends out of the receiving groove and is located within the can-receiving cavity 22. An inclined end face 51 corresponding to the can 1 is formed on the spring clip 5. This arrangement allows the spring clip 5 to prevent the can 1 from falling out, thereby limiting the position of the can 1.

[0034] Specifically, the can 1 is loaded between the spring clip 5 and the pusher block 15. After loading, the center of gravity of the can 1 acts directly on the inner wall of the cylinder 3. The spring clip 5 abuts against the side of the can 1 near the can outlet 25 to limit it and prevent the can 1 from falling out. When discharging, the drive assembly drives the pusher block 15 to move, and the pusher block 15 pushes the can 1 to move. When the can 1 moves, it abuts against the inclined end face 51. Under the continuous pushing force, the can 1 slides along the inclined end face 51 and pushes the spring clip 5 to retract relative to the receiving groove and compress the spring 6. When the can 1 moves beyond the spring clip 5 and is discharged from the can outlet 25, the drive assembly stops and the spring clip 5 is pushed back to the initial position by the rebound force of the spring 6.

[0035] The inclined end face 51 is located on the side of the spring buckle 5 facing the pusher block 15; preferably, the receiving groove is located on the outer wall of the can outlet 25.

[0036] Furthermore, the can outlet 25 is connected to a guide bracket 10, which in turn is connected to a discharge bracket 11. The discharge bracket 11 has a can discharge port 23, forming a can discharge channel between the can outlet 25 and the can discharge port 23. With this configuration, after the can 1 is discharged through the can outlet 25, it passes through the can discharge channel and is then discharged through the can discharge port 23. The can discharge channel serves to guide and buffer the material.

[0037] Preferably, the inner wall of the feeding bracket 11 is formed with a guide slope, and the inner wall of the feeding bracket 10 is provided with an inclined guide plate 9, with the higher end of the guide plate 9 connected to the can outlet 25; the material cylinder 3 is provided with a transparent lens 2 corresponding to the can feeding channel, which can be used to observe the situation inside the can feeding channel.

[0038] Furthermore, the feeding support 11 is equipped with a can sensing component.

[0039] The can sensor assembly includes an infrared emitter 12 and an infrared receiver 13, which are symmetrically mounted on the outer wall of the feeding bracket 11. When the can 1 is fed through the can feeding channel, the infrared emitter 12 and the infrared receiver 13 sense that the can 1 is passing through. When the infrared emitter 12 and the infrared receiver 13 sense that no can 1 is passing through, it indicates that there is a shortage of material and that it needs to be replenished.

[0040] Preferably, there are two can receiving cavities 22, and correspondingly two can feeding devices; when the cans 1 in the first can receiving cavity 22 have finished feeding, and the infrared emitting tube 12 and the infrared receiving tube 13 sense that no cans 1 have passed through, the feeding is switched to the second can receiving cavity 22, and the first can receiving cavity 22 is prompted to replenish the material; when the infrared emitting tube 12 and the infrared receiving tube 13 sense that no cans 1 have passed through, the feeding is switched to the first can receiving cavity 22, and the second can receiving cavity 22 is prompted to replenish the material.

[0041] The pet feeder of the present invention includes the above-mentioned can feeding and dispensing assembly.
