Description

Technical Field

[0001] This invention relates to the field of pet feeding equipment technology, specifically to a fully automatic pet canned food opening and feeding machine. Background Technology

[0002] Traditional pet food is mainly extruded, which is convenient to store and feed. However, due to its processing method, extruded food suffers from significant nutrient loss and requires the addition of various food additives. Therefore, more and more people are choosing canned pet food for their pets.

[0003] Currently, feeding pet canned food usually requires manual opening of the can. This is not only cumbersome but also time-consuming and labor-intensive, especially for owners with mobility issues. Furthermore, manual opening poses a risk of cuts and injuries, creating a safety hazard. Therefore, there is an urgent need for a pet canned food feeder that can automatically dispense and open cans. Summary of the Invention

[0004] To address some or all of the problems existing in the prior art, this invention provides a fully automatic pet food can opening and feeding machine, comprising a base and a controller. The base is equipped with an automatic feeding assembly, a cap-cutting mechanism, a cap-removing mechanism, and a feeding mechanism, all connected to the controller. The base also includes a cap-opening processing position, a feeding trough, and an empty can collection port. The automatic feeding assembly includes a turntable, a rotary feeding mechanism, and a pushing mechanism. The turntable is rotatably connected to the base. Multiple placement slots are evenly distributed around the turntable, used to hold cans. The rotary feeding mechanism drives the turntable to rotate. The pushing mechanism is connected to both the turntable and the cap-opening processing position, pushing the cans from the placement slots to the cap-opening processing position. The feeding mechanism is connected to the can opening processing position, the feeding trough, and the empty can collection port. The feeding mechanism can push cans on the can opening processing position into the feeding trough, and can push empty cans in the feeding trough to the can opening processing position, and can also push empty cans to the empty can collection port. The cap cutting mechanism and the cap removing mechanism are connected to the can opening processing position. The cap cutting mechanism is used to cut open the can caps on the can opening processing position, and the cap removing mechanism is used to remove the can caps on the can opening processing position and can put the can caps back onto the empty cans on the can opening processing position. An empty can collection box is provided on the machine base. The empty can collection box is detachably connected to the machine base and is located below the empty can collection port.

[0005] As a further improvement of the present invention, the rotary feeding mechanism includes a rotary motor connected to the base. The output end of the rotary motor is provided with a rotating shaft, which can drive the rotating shaft to rotate. The rotating shaft is connected to the center position of the turntable. By driving the turntable to rotate through the rotary motor, each placement slot is aligned with the cap opening processing position. The outer wall of the placement slot is provided with a discharge notch, and the pushing mechanism can push the canned food in the placement slot out of the discharge notch and push it to the cap opening processing position.

[0006] As a further improvement of the present invention, the pushing mechanism includes a pushing motor and a pushing rod. The pushing motor is connected to the base, and the pushing rod is slidably connected to the base. A pushing gear is provided on the output end of the pushing motor, and a pushing rack is provided on the pushing rod. The pushing rack is meshed with the pushing gear. The pushing motor can drive the pushing gear to rotate, thereby driving the pushing rod to extend into or out of the placement groove.

[0007] As a further improvement of the present invention, a material receiving sensor is provided on the machine base at a position corresponding to the opening processing position. The material receiving sensor is connected to the controller and is used to detect whether there is a can in the placement slot corresponding to the opening processing position.

[0008] As a further improvement of the present invention, the lid-cutting mechanism includes a cutting lifting assembly and a cutting blade assembly. The cutting lifting assembly is connected to the base, and the cutting blade assembly is connected to the output end of the cutting lifting assembly. The cutting lifting assembly is used to drive the cutting blade assembly to engage or disengage with the can at the lid-opening processing position. The cutting blade assembly is used to push the can to rotate at the lid-opening processing position and cut the lid of the can at the lid-opening processing position.

[0009] As a further improvement of the present invention, the cutting assembly includes a cutting mounting base, on which a lid-opening motor and a rotatable lid-cutting blade are provided. A rotating shaft is provided at the output end of the lid-opening motor, and a meshing gear is provided on the rotating shaft. The cutting lifting assembly can drive the lid-cutting blade to abut against the side wall of the can lid at the lid-opening processing position, and can drive the meshing gear to abut against the upper surface of the can at the lid-opening processing position. The lid-opening motor is used to drive the meshing gear to rotate, thereby causing the can to rotate in place at the lid-opening processing position. A conical limiting wheel is provided on the rotating shaft, and the cutting lifting assembly can drive the conical limiting wheel to engage with the flange of the can lid at the lid-opening processing position.

[0010] As a further improvement of the present invention, the cutting lifting assembly includes a cutting lifting motor, which is connected to the base.

[0011] As a further improvement of the present invention, the cap-removing mechanism includes a cap-removing drive assembly and a cap-removing moving shaft. The base is provided with a cap-removing sleeve. One end of the cap-removing moving shaft extends into the cap-removing sleeve and slides in cooperation with the cap-removing sleeve. The cap-removing moving shaft is connected to the output end of the cap-removing drive assembly. One end of the cap-removing moving shaft is provided with a magnetic element. The cap-removing drive assembly can drive the cap-removing moving shaft to slide inside the cap-removing sleeve, thereby driving the magnetic element to move closer to or away from the cap-opening processing position. The magnetic element is used to attract the can caps on the cap-opening processing position.

[0012] As a further improvement of the present invention, the inner diameter of the cap-removing sleeve is larger than the diameter of the magnetic component, and the inner diameter of the cap-removing sleeve is smaller than the diameter of the can lid.

[0013] As a further improvement of the present invention, the feeding mechanism includes a feeding motor and a pushing block.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figure 1-8As shown, a fully automatic pet canned food opening and feeding machine includes a base 100 and a controller (not shown). The controller can be a PLC, a microcontroller, or an existing control device, and integrates a control system to control the various mechanisms of the fully automatic pet canned food opening and feeding machine to operate according to a preset program. The base 100 is equipped with an automatic feeding assembly, a cap-cutting mechanism 1, a cap-removing mechanism 2, and a feeding mechanism 3, all connected to the controller. The base 100 also has a cap-opening processing position 101, a feeding trough 102, and an empty can collection port 103. The cap-opening processing position 101 is the working area for opening cans, used to fix the cans and perform the cap-opening operation; the feeding trough 102 is the position for pets to eat; and the empty can collection port 103 is connected to a collection channel for recycling empty cans. The automatic feeding assembly stores the cans and transports them one by one to the cap-opening processing position 101. The cap-cutting mechanism 1 and the cap-removing mechanism 2 are respectively connected to the cap-opening processing station 101. The cap-cutting mechanism 1 is used to cut open the can cap 9 on the cap-opening processing station 101, and the cap-removing mechanism 2 is used to remove the can cap 9 from the cap-opening processing station 101 and can put the can cap 9 back onto the empty can on the cap-opening processing station 101. The feeding mechanism 3 is respectively connected to the cap-opening processing station 101, the feeding trough 102 and the empty can collection port 103. The feeding mechanism 3 can push the can with the cap 9 cut off on the cap-opening processing station 101 into the feeding trough 102, and can push the empty can in the feeding trough 102 onto the cap-opening processing station 101, and can also push the empty can to the empty can collection port 103.

[0021] Before operation, manual placement of canned food onto the automatic feeding assembly is required. When the fully automatic pet food can opener and feeder is working, the automatic feeding assembly pushes the cans to the opening processing station 101; then, the lid-cutting mechanism 1 cuts open the can lid 9 on the opening processing station 101; then, the lid-removing mechanism 2 removes the cut can lid 9; finally, the feeding mechanism 3 pushes the opened can to the feeding trough 102 for the pet to eat, thus completing the opening and automatic feeding process. After the pet finishes eating the can in the feeding trough 102, the feeding mechanism 3 pushes the empty can back to the opening processing station 101; then, the lid-removing mechanism 2 places the can lid 9 back onto the empty can; finally, the feeding mechanism 3 pushes the empty can with the lid 9 back onto the empty can collection port 103, where the empty can falls for recycling.

[0022] The can opening processing station 101 has perforated holes 104 on its surface to facilitate the dropping of residue and liquid. An empty can collection box 4 is installed on the base 100, located below the can opening processing station 101 and the empty can return port 103. When an empty can is pushed to the empty can return port 103, it will fall through the port 103 into the empty can collection box 4 under its own weight, where it is collected. Simultaneously, during the can opening process at the can opening processing station 101, some residue and liquid inevitably spill out, which will fall through the perforated holes 104 into the empty can collection box 4 for collection.

[0023] In this embodiment, the empty can collection box 4 is connected to the drawer of the base 100. To facilitate pulling out, a handle 41 is provided on the outer side wall of the empty can collection box 4. Users can easily load and unload the empty can collection box 4 on the base 100 by holding the handle 41, which improves the convenience of operation.

[0024] like Figure 3-4 As shown, the automatic feeding assembly includes a turntable 5, a rotary feeding mechanism 6, and a pushing mechanism 7. The turntable 5 is rotatably connected to the base 100. Ten placement slots 51 are evenly distributed along the circumference of the turntable 5. The shape of each placement slot 51 is adapted to the outline of the can to be opened, and the placement slots 51 are used to hold the cans. The multiple placement slots 51 distributed circumferentially on the turntable 5 form a small storage bin, enabling batch loading and sequential feeding of cans. In other embodiments, the number of placement slots 51 can be any other number. The output end of the rotary feeding mechanism 6 is connected to the turntable 5 and is used to drive the turntable 5 to rotate on the base 100. By driving the turntable 5 to rotate, each placement slot 51 on the turntable 5 can be aligned with the pushing mechanism 7 and the cap-opening processing position 101, respectively. The pushing mechanism 7 is connected to both the turntable 5 and the cap-opening processing position 101, and is used to push the cans on the placement slots 51 onto the cap-opening processing position 101.

[0025] Before use, the cans to be opened are manually placed into their respective placement slots 51. During operation, the rotary feeding mechanism 6 drives the turntable 5 to rotate, aligning the placement slot 51 with the opening processing position 101. Then, the pushing mechanism 7 pushes the can out of the placement slot 51 aligned with the opening processing position 101 and onto it, achieving automatic feeding. After feeding one can, the pushing mechanism 7 automatically resets, and the rotary feeding mechanism 6 drives the turntable 5 to rotate again, aligning the next placement slot 51 with the opening processing position 101. This cycle repeats, achieving continuous feeding.

[0026] The rotary feeding mechanism 6 includes a rotary motor 61 fixedly mounted on the base 100. A rotating shaft 62 is connected to the output shaft of the rotary motor 61 via a coupling, and the rotating shaft 62 is fixedly connected to the center position of the turntable 5. The rotary motor 61 operates under the control command of the controller, driving the rotating shaft 62 and the turntable 5 to rotate intermittently at a set angle (e.g., 36° each time), so that the ten placement slots 51 are aligned sequentially with the cap-opening processing position 101, so that the pushing mechanism 7 pushes the cans in the placement slots 51 onto the cap-opening processing position 101.

[0027] The pushing mechanism 7 is located inside the turntable 5 and aligned with the cap-opening processing position 101. The pushing mechanism 7 includes a pushing motor 71 and a pushing rod 72. The pushing motor 71 is fixedly mounted on the machine base 100, and the pushing rod 72 is slidably limited to the machine base 100. The central axis of the pushing rod 72 points towards the center of the turntable 5. A pushing gear 73 is mounted on the output shaft of the pushing motor 71, and a pushing rack 74 is provided on the pushing rod 72. The pushing gear 73 meshes with the pushing rack 74. The pushing motor 71 drives the pushing gear 73 to rotate, thereby causing the pushing rod 72 to extend into or out of the placement slot 51. The pushing rod 72 pushes the canned goods out of the placement slot 51 and onto the cap-opening processing position 101.

[0028] In actual operation, when the turntable 5 rotates, the placement slot 51 containing the canned goods is moved to be aligned with the opening processing position 101; the pusher motor 71 is controlled to work, driving the pusher gear 73 to rotate, which in turn drives the pusher rack 74 and pusher rod 72 to extend into the placement slot 51. The pusher rod 72 pushes the canned goods out of the placement slot 51 and pushes them onto the opening processing position 101 to complete the feeding; then the pusher motor 71 is controlled to reverse, driving the pusher gear 73 to rotate in the opposite direction, which in turn drives the pusher rack 74 and pusher rod 72 to retract into the placement slot 51, so that the rotary motor 61 can continue to drive the turntable 5 to rotate, thus achieving continuous feeding.

[0029] In other embodiments, the gear and rack structure in the pusher mechanism 7 can also be replaced by any other existing linear drive device such as a motor synchronous belt structure, a motor lead screw structure, or an electric cylinder drive structure.

[0030] like Figure 5 As shown, in order to facilitate the ejection of cans from the placement slot 51, a discharge notch 52 is provided on the outer wall of the placement slot 51 facing the opening processing position 101. The movement path of the push rod 72 is aligned with the discharge notch 52, which can smoothly eject the cans from the placement slot 51 from the discharge notch 52 and enter the opening processing position 101 along a predetermined track.

[0031] To achieve automatic control, a material inlet sensor 8 (such as an infrared sensor or a photoelectric sensor) is provided on the base 100 at a position corresponding to the lid opening processing position 101. The material inlet sensor 8 is used to detect whether there are cans in the placement slot 51 that is aligned with the lid opening processing position 101, and feeds the signal back to the controller to coordinate the control of the rotation feeding and pushing actions.

[0032] To improve safety and aesthetics, the base 100 is equipped with an upper cover 9, which covers the outer perimeter of the turntable 5 to form a protective layer. The upper cover 9 and the base 100 are closable for easy loading and maintenance. A handle 91 is provided at the top of the upper cover 9 for easy opening by the user.

[0033] like Figure 2 , Figure 6 As shown, the feeding mechanism 3 includes a feeding motor 31 and a pusher block 32. The feeding motor 31 is fixed on the base 100. The pusher block 32 is fixedly connected to the output shaft of the feeding motor 31. One or more receiving notches 33 are provided on the outer side of the pusher block 32. The pusher rod 72 can push the cans in the placement slot 51 through the receiving notches 33 into the opening processing position 101. The feeding motor 31 can drive the pusher block 32 to rotate, so that the receiving notches 33 are sequentially aligned with the opening processing position 101, the feeding slot 102 and the empty can collection port 103, thereby realizing the transfer of cans / empty cans between different positions. In the initial state, the receiving notch 33 is located on the opening processing position 101. During operation, the pusher rod 72 pushes the can through the receiving notch 33 and into the opening processing position 101. The lid 9 of the can is cut open and removed by the lid cutting mechanism 1 and the lid removal mechanism 2. Then, the feeding motor 31 drives the pusher block 32 to rotate 180° forward, so that the receiving notch 33 is aligned with the feeding trough 102. The pusher block 32 will push the can with the lid 9 opened on the opening processing position 101 to the feeding trough 102, realizing the automatic feeding of the can. After the pet finishes eating the canned food in the feeding trough 102, the feeding motor 31 drives the pusher block 32 to rotate 180°, causing the receiving notch 33 to align with the lid-opening processing position 101. The pusher block 32 then pushes the empty can from the feeding trough 102 to the lid-opening processing position 101, and the lid-removing mechanism 2 places the lid 9 back onto the empty can. Next, the feeding motor 31 drives the pusher block 32 to rotate 90°, aligning the receiving notch 33 with the empty can collection port 103. The pusher block 32 then pushes the empty can with the lid 9 closed to the empty can collection port 103, where the empty can falls into the empty can collection box 4 under its own weight. Finally, the feeding motor 31 drives the pusher block 32 to rotate 90° forward, causing the receiving notch 33 on the pusher block 32 to return to its original position aligned with the lid-opening processing position 101. Repeat the above process to achieve continuous automatic feeding of canned food.

[0034] like Figure 2 , Figure 7 As shown, the lid-cutting mechanism 1 includes a cutting and lifting assembly 11 and a cutting blade assembly 12. The cutting and lifting assembly 11 is connected to the base 100, and the cutting blade assembly 12 is connected to the output end of the cutting and lifting assembly 11. The cutting and lifting assembly 11 is used to drive the cutting blade assembly 12 to engage or disengage from the can on the lid-opening processing position 101. The cutting blade assembly 12 is used to push the can to rotate on the lid-opening processing position 101 and cut open the lid 9 of the can on the lid-opening processing position 101.

[0035] Specifically, the cutter assembly 12 includes a cutter mounting base 121, which is connected to the output end of the cutting lifting assembly 11. The cutter mounting base 121 is equipped with a cap-opening motor 122 and a rotatable cap-cutting blade 123. A rotating shaft 124 is connected to the output shaft of the cap-opening motor 122, and a meshing gear 125 is mounted on the rotating shaft 124. The cap-opening motor 122 drives the meshing gear 125 to rotate via the rotating shaft 124. The cutting lifting assembly 11 can drive the cap-cutting blade 123 to abut against the side wall of the can cap 9 on the cap-opening processing position 101, and can also drive the meshing gear 125 to abut against the upper surface of the can on the cap-opening processing position 101. The cap-opening motor 122 drives the meshing gear 125 to rotate, thereby causing the can to rotate in place on the cap-opening processing position 101. After the pusher rod 72 pushes the can to the opening processing position 101, the cutting lifting assembly 11 is controlled to drive the cutter mounting base 121 to descend, so that the lid cutting blade 123 contacts the side wall of the can lid, and at the same time the meshing gear 125 meshes with the upper surface of the can. Then the opening motor 122 is controlled to start, and the meshing gear 125 drives the can to rotate in place on the opening processing position 101. The lid cutting blade 123 cuts in a ring along the side wall of the can lid, completely cutting the can lid 9 on the opening processing position 101, thus realizing the lid cutting function.

[0036] To prevent the can from shifting during the cap-cutting process, a conical limiting wheel 126 is provided on the rotating shaft 124. The conical limiting wheel 126 is located on the side of the meshing gear 125 away from the cap motor 122. The cutting lifting assembly 11 can drive the conical limiting wheel 126 to engage with the flange of the can cap 9 on the cap-opening processing position 101. During the cap-cutting process, when the meshing gear 125 abuts against the upper surface of the can, the conical limiting wheel 126 can also engage the flange of the can cap 9. The conical limiting wheel 126 can limit the can to rotate only in place at the can processing position, ensuring the stability of the cap-cutting operation.

[0037] The cutting and lifting assembly 11 includes a cutting and lifting motor 111, which is connected to the base 100. A cutting and lifting gear 112 is mounted on the output end of the cutting and lifting motor 111, and a cutting and lifting rack 113 is mounted on the cutter mounting base 121. The cutting and lifting rack 113 meshes with the cutting and lifting gear 112. By controlling the operation of the cutting and lifting motor 111, the cutting and lifting gear 112 can be driven to rotate, thereby driving the cutting and lifting rack 113 to move up and down. The cutting and lifting rack 113 will then drive the cutter mounting base 121 to move synchronously, thus achieving the purpose of driving the cutting assembly 12 to move up and down.

[0038] In other embodiments, the gear and rack structure in the cutting and lifting assembly 11 can also be replaced by any other existing linear drive device such as a motor synchronous belt structure, a motor lead screw structure, or an electric cylinder drive structure.

[0039] To limit and guide the lifting movement of the cutter assembly 12, at least two lifting guide rods 114 are provided on the base 100. The lifting guide rods 114 pass through the cutter mounting base 121 and are slidably engaged with it. When the cutting lifting motor 111 operates, the cutter mounting base 121 slides on the lifting guide rods 114. Through the sliding engagement between the lifting guide rods 114 and the cutter mounting base 121, the lifting movement of the cutter mounting base 121 is limited and guided, improving the stability and accuracy of the machining process.

[0040] like Figure 2 , Figure 8 As shown, the cap-removing mechanism 2 includes a cap-removing drive assembly 21 and a cap-removing moving shaft 22. A cap-removing sleeve 23 is provided on the base 100. One end of the cap-removing moving shaft 22 extends into the cap-removing sleeve 23 and slides within it. The cap-removing moving shaft 22 is connected to the output end of the cap-removing drive assembly 21. A magnetic element 24, which can be a permanent magnet, is provided at one end of the cap-removing moving shaft 22. The cap-removing drive assembly 21 drives the cap-removing moving shaft 22 to slide within the cap-removing sleeve 23, thereby causing the magnetic element 24 to move closer to or further away from the cap processing position 101. The magnetic element 24 is used to attract the can caps 9 on the cap-opening processing position 101. During operation, after the cap-cutting mechanism 1 cuts open the can lid 9 on the cap-opening processing position 101, the cap-removing drive assembly 21 drives the cap-removing moving shaft 22 to slide downwards within the cap-removing sleeve 23, causing the magnetic component 24 to move towards the can on the cap-opening processing position 101 until the magnetic component 24 comes into contact with the can lid 9. The magnetic component 24 will then attract the cut can lid 9. Afterwards, the cap-removing drive assembly 21 drives the cap-removing moving shaft 22 to move the magnetic component 24 upwards, and the magnetic component 24 will pull away the cut can lid 9, thus completing the can lid removal action.

[0041] To facilitate the repositioning of the can top cover 9 onto the empty can, in this embodiment, the inner diameter of the can top cover removal sleeve 23 is set to be larger than the diameter of the magnetic component 24 and smaller than the diameter of the can top cover 9. During operation, the magnetic component 24 attracts the can top cover 9 and lifts it up, allowing the can top cover 9 to be removed from the can. At this time, the magnetic component 24 cannot be completely retracted into the can top cover removal sleeve 23. When the can lid 9 needs to be placed back onto the empty can, the lid removal drive assembly 21 drives the lid removal moving shaft 22 to continue sliding the magnetic component 24 upward, so that the magnetic component 24 extends into the lid removal sleeve 23. Because the can lid 9 is attracted to the magnetic component 24, and the diameter of the can lid 9 is larger than the diameter of the lid removal sleeve 23, when the magnetic component 24 extends into the lid removal sleeve 23, the lid removal sleeve 23 will block the can lid 9, causing it to detach from the magnetic component 24. The detached can lid 9 will automatically fall onto the empty can on the lid opening processing position 101, completing the re-closing action of the lid 9.

[0042] In this embodiment, the cap removal drive assembly 21 includes a cap removal motor 211, which is fixedly mounted on the base 100. A cap removal gear 212 is mounted on the output shaft of the cap removal motor 211, and a cap removal rack 213 is fixedly mounted on the cap removal moving shaft 22. The cap removal rack 213 is meshed with the cap removal gear 212. During operation, by controlling the cap removal motor 211, the cap removal gear 212 can be driven to rotate. The cap removal gear 212 drives the cap removal rack 213 to move the cap removal moving shaft 22 up and down and slide within the cap removal sleeve 23, thereby realizing the cap removal and cap placement actions.

[0043] In other embodiments, the gear and rack structure in the cover removal drive assembly 21 can also be replaced by any other existing linear drive device such as a motor synchronous belt structure, a motor lead screw structure, or an electric cylinder drive structure.

[0044] Working principle: Before operation, the canned food is manually placed into the placement slot 51 of the turntable 5. When the fully automatic pet food can opener and feeder is working, the rotary motor 61 drives the turntable 5 to rotate, aligning the placement slot 51 containing the canned food with the opening processing position 101. When the feeding sensor 8 detects that there is a canned food in the placement slot 51 aligned with the opening processing position 101, it controls the pushing motor 71 to drive the pushing rod 72, pushing the canned food in the placement slot 51 into the opening processing position 101.

[0045] After the can is pushed to the opening processing position 101, the cutting lifting motor 111 drives the entire cutting assembly 12 to descend. This causes the cap-cutting blade 123 to contact the side wall of the can lid, while the meshing gear 125 engages with the upper surface of the can, and the conical limiting wheel 126 locks the can lid flange. Then, the opening motor 122 is started, and the meshing gear 125 drives the can to rotate in place, allowing the cap-cutting blade 123 to complete a circular cut, cutting open the can lid 9. After the can lid 9 is cut open, the cap-removing motor 211 drives the cap-removing moving shaft 22 to descend, causing the magnetic component 24 at its end to attract the cut can lid 9. Subsequently, the cap-removing moving shaft 22 rises, sucking the can lid away from the can body; at this time, the magnetic component 24 cannot retract back into the cap-removing sleeve 23. After the can lid 9 is removed, the feeding motor 31 drives the pusher block 32 to rotate 180° clockwise. The pusher block 32 pushes the opened can from the can opening processing position 101 to the feeding trough 102 for the pet to eat. The residue and juice generated during the cutting and lid removal process fall into the empty can collection box 4 below through the perforated hole 104 of the can opening processing position 101.

[0046] After the pet finishes eating, the feeding motor 31 drives the pusher block 32 to rotate 180°, pushing the empty can in the feeding trough 102 back to the opening processing position 101. Then, the cap-removing motor 211 drives the cap-removing moving shaft 22 to continue rising, causing the magnetic component 24 holding the cap to retract into the cap-removing sleeve 23. Since the diameter of the can cap 9 is larger than the inner diameter of the cap-removing sleeve 23, the cap-removing sleeve 23 will block the can cap 9, causing the can cap 9 to detach from the magnetic component 24. The detached can cap 9 will automatically fall onto the empty can on the opening processing position 101. Afterward, the feeding motor 31 drives the pusher block 32 to rotate 90° again, aligning its receiving notch 33 with the empty can collection port 103. The pusher block 32 pushes the capped empty can into the empty can collection port 103, and the empty can falls into the empty can collection box 4 under gravity. Then, the feeding motor 31 drives the pusher block 32 to rotate 90° clockwise, resetting the receiving notch 33 and realigning it with the can opening processing position 101. The machine returns to its initial state, ready to begin the next can feeding and dispensing cycle.
