This invention relates to the field of intelligent self-service equipment technology, and discloses a juicer that can automatically pick up fruit, peel fruit, and blend fruit for juicing. It includes a frame, a juicing module, a synchronous cup-dropping and capping module, and a purely mechanical linkage mechanism. A juice-receiving servo motor drives a connecting frame with a cup holder to swing between the juice-receiving station and the cup-retrieving station.

Description

Technical Field

[0001] This invention relates to the field of intelligent self-service equipment technology, specifically a juicer that can automatically pick up fruit, peel fruit, and mix fruit for juicing. Background Technology

[0002] With the increasing demand for healthy eating, freshly squeezed juice has huge market potential in the unmanned retail sector. However, there is currently no fully functional freshly squeezed juice machine on the market that integrates automatic fruit grabbing, automatic peeling, multi-fruit juicing, and fully automatic cup capping. Most existing commercial self-service juice machines can only process fruits of a single type or require manual pre-cutting of the pulp. The functional modules are isolated from each other, making it impossible to achieve unmanned and automated operation of the entire process from raw fruit to finished product.

[0003] Meanwhile, in the process of exploring the development of such highly integrated, full-featured devices within the industry, insurmountable technical bottlenecks are often exposed:

[0004] First, if a complex multi-station action such as cup taking, juice receiving, anti-splash funnel placement, and protective door opening and closing is to be integrated into a single device, the traditional R&D approach usually adopts an electronic control stacking solution with one motor and one sensor per action. However, in the harsh operating environment of high temperature, high humidity, and high sugar content inside a juicer, a large number of electronic position sensors are easily affected by moisture or contaminated by juice and malfunction, resulting in garbled internal control programs, disordered action timing, and an extremely high failure rate of the entire machine, which simply cannot meet the requirements for commercial deployment.

[0005] Secondly, in the automatic cup dropping and capping process of plastic juice cups, most existing packaging equipment adopts a single-point push rod or double-sided paddle structure. Because disposable plastic soft cups and cup lids are highly flexible, local single-point force can easily cause uneven force on the cup edge, resulting in tilting or jamming in the hopper. Especially during fully automatic capping, the unbalanced force will directly cause the cup lid to tilt up on one side, making it impossible to seal completely and causing juice leakage.

[0006] Therefore, how to break through the aforementioned technical barriers, abandon redundant electronic control schemes, and develop a truly full-function, highly stable, and perfectly leak-proof new type of fresh juicer to fill the market gap has become an urgent technical problem to be solved in this field. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a juicer that can automatically pick up fruit, peel fruit, and mix fruits for juicing.

[0012] Preferably, the automatic door opening mechanism further includes a protective door and a torsion spring; the protective door with the torsion spring is vertically hinged to the main housing of the equipment, and the torsion spring is configured to apply a closing preload force to the protective door; the lower edge of the protective door abuts against the horizontal rotation trajectory plane of the door stop base plate, and is configured to be opened by the pressure of the rotating door stop base plate to overcome the spring force of the torsion spring.

[0018] This invention provides a juicer that can automatically pick up fruit, peel fruit, and mix and juice fruit. It has the following beneficial effects:

[0019] 1. The core innovation of this invention lies in using the juice receiving cup as the sole displacement body and the gear carried on top of it as a mechanical trigger key. The juice receiving motor only needs to achieve simple translation and swing through pulse signals. When it moves to the specific work position of receiving juice or taking the cup, it uses the natural interference of the spatial gear position to mechanically trigger the funnel to be lowered or the protective door to be opened. The design of eliminating independent action motors and relying entirely on spatial coordinate triggering eliminates control code disorder from the physical structure, greatly reduces the wiring and cost of the machine body, and has extremely high commercial reliability.

[0020] 2. The cup and lid dropping module of this invention abandons the traditional single-sided push rod mechanism. Instead, it uses a motor connected in series with a dual-path large gear ring to drive multiple threaded rods distributed around the cup and lid rims to rotate synchronously. This multi-point uniform force application, similar to a planetary mechanism, ensures that the flexible plastic cup experiences absolutely balanced force during peeling and pressing to seal, completely solving the industry pain points of single-sided tilting and jamming and single-sided leakage when pressing the lid, which are very common in traditional machines.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please refer to the accompanying drawings. This invention provides a juicer that can automatically pick up fruit, peel fruit, and mix fruit for juicing. It aims to solve the problems of redundant control, high failure rate, and large size caused by multiple actuators in the prior art, as well as the problems of cup jamming and poor lid sealing caused by a single feeding point.

[0036] This equipment includes a main housing consisting of an insulated box panel 1, an electrical door 2 with an electrical cabinet 202, and a main cabinet door 3. The electrical door 2 has a straw opening 201, and the main cabinet door 3 has a cup-taking opening 301 and an inspection opening 302 corresponding to the cup-taking station, forming the external support and human-machine interaction framework of the equipment. Inside the main housing, there is a frame for supporting various transmission components and power components. The core operation of this equipment mainly relies on several core drive sources distributed at different workstations, including a juice-taking servo motor 701 for driving the juice-taking linkage module and a brushless motor 8 for driving the synchronous cup-dropping and capping module.

[0037] The servo motor 701 is preferably an AC servo motor of model 60M01330 with a rated power of approximately 400W. It can provide high-precision angular displacement control and extremely fast response speed, thereby ensuring the precise hovering and interference of the mechanical trigger between different workstations. The brushless motor 8 is preferably a DC brushless motor of model BLDC-57 with a rated power of 100W. It has the characteristics of small size and stable transient speed, which can ensure absolute synchronization when distributing to multiple points through the planetary gear system and prevent jamming.

[0038] Reference Figures 7-8 In this invention, the core actuator for achieving pure mechanical linkage between juice receiving and anti-drip door opening includes a juice receiving servo motor 701, which is vertically inverted and fixedly connected to the main plate of the frame. The output end of the juice receiving servo motor 701 is coaxially fixedly connected to the top of the connecting frame 702, thereby converting the rotation of the motor into the horizontal fixed-axis swing of the connecting frame 702. The bottom of the connecting frame 702 is coaxially fixedly connected to a sector-shaped power gear 703, and a cup holder 704 is suspended and fixedly attached to the lower part of the connecting frame 702. The sector-shaped power gear 703 serves as a mechanical linkage trigger, configured to trigger the anti-splash mechanism at the juice receiving station and the automatic door opening mechanism at the cup retrieval station.

[0039] A splash-proof mechanism is installed on the frame at the juice receiving station. This mechanism includes a vertically rotatably connected linkage rod 706. The bottom end of the linkage rod 706 is coaxially and fixedly connected to a sector driven gear 705. The sector driven gear 705 is arranged on the swing trajectory of the sector power gear 703 and can mesh with it. A rocker arm is fixedly connected to the upper end of the linkage rod 706. A spring reciprocating rod 707 slides through a guide member provided on the frame. One end of the spring reciprocating rod 707 is hinged to the rocker arm, and the other end is eccentrically hinged to a rotating rod 708. The rotating rod 708 is horizontally rotatably connected to the frame, and its other end is fixedly connected to the juice receiving tipping bucket 709. When the connecting frame 702 reaches the juice receiving station, the gear meshes and drives the rocker arm to rotate, converting the circumferential rotation into a linear motion that pulls the spring reciprocating rod 707, thereby achieving the precise flipping and pressing of the juice receiving tipping bucket 709.

[0040] An automatic door opening mechanism is provided on the base plate of the frame at the cup-taking station. This mechanism includes a juice-receiving driven gear 710 and a juice-receiving transmission gear 711 that are rotatably connected to the base plate and mesh with each other. The juice-receiving driven gear 710 is also arranged on the swing trajectory surface of the sector-shaped power gear 703. The juice-receiving transmission gear 711 is coaxially fixedly connected to the sector-shaped door stop base plate 712, and the protective door 713 with a torsion spring 714 is hinged to the main housing of the equipment. The lower edge of the protective door 713 abuts against the horizontal rotation trajectory surface of the door stop base plate 712. When the connecting frame 702 reaches the cup-taking station, the gear meshing drives the door stop base plate 712 to rotate horizontally, thereby forcibly overcoming the elastic force of the torsion spring 714 to achieve physical door opening.

[0041] Reference Figures 9-12 In this invention, the core actuator for achieving synchronized cup and lid dropping includes a brushless motor 8 vertically fixed to the upper part of the frame. Its output end is coaxially and fixedly connected to a cup-dispensing power gear 801. The cup-dispensing power gear 801 meshes with the outer teeth of a horizontally rotatable cup-dispensing driven gear ring 802. Multiple threaded cup-dispensing rings 803 are evenly distributed on the inner circumference of the cup-dispensing driven gear ring 802, and these multiple threaded cup-dispensing rings 803 are rotatably connected to the frame and mesh with the inner teeth of the cup-dispensing driven gear ring 802, thereby constructing a... In the planetary transmission system, the output end of the brushless motor 8 extends downwards and is connected to the lower lid-driven gear ring 806 via the lid-out transmission rod 805 rotatably connected to the lid-out connecting plate 804. The inner teeth of the lid-out driven gear ring 806 mesh with multiple lid-out driven gears 807 rotatably connected to the frame. Each lid-out driven gear 807 is vertically and coaxially connected to a lid-out threaded rod 808 and a lid-pressing threaded rod 809, thereby achieving the peeling and circumferential uniform pressing of the cup lid using the synchronously downward spiral surface.

[0042] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0043] As a preferred implementation method, in order to achieve smooth automatic feeding of fruit, refer to Figure 1 The top of the equipment is equipped with a fruit storage rack 4 with an inclined fruit passage 406; an external AC geared motor is installed in this module.

[0044] The external AC geared motor is preferably a YN90-40 geared motor with a rated power of 40W, which can output a stable high torque at low speed, thereby ensuring smooth flow without jamming when fully loaded with fruit.

[0045] The output end of the external AC geared motor is coaxially and fixedly connected to the gearbox 401. The output end of the gearbox 401 is fixedly connected to the power gear 403 through the transmission rod 402. A chain 405 is wound between the power gear 403 and the driven gear 404. The fruit is precisely guided along the fruit passage 406 to be flush with the fruit-grabbing module 5 by the paddle on the chain, so that the fruit-grabbing module 5 can grab the fruit. The fruit-grabbing module 5 then feeds the fruit to the peeling module 501 for the peeling step.

[0046] As a preferred embodiment, in order to achieve skinless pressing and prevent the motor from being damaged by moisture, refer to Figure 5 The side of the fruit discharge end is provided with a fruit gripping module 5, a peeling module 501 and a juicing module. The juicing module includes a juicing box 6, which includes a juicing shell 604 that is vertically fixed and nested with a filter box 606. A juicing servo motor 601 is provided on the bottom frame of this module.

[0047] The juicing servo motor 601 is preferably an AC servo motor of model 80M02430, with a rated horsepower of about 750W, which can output extremely high low-frequency extrusion torque, thereby thoroughly crushing the peeled pulp and greatly improving the juice yield.

[0048] The output end of the juicing servo motor 601 extends upward and is coaxially and fixedly connected to the juicing transmission gear 602. The juicing transmission gear 602 meshes with the juicing driven gear 603. The central axis of the juicing driven gear 603 passes upward through the bottom plate of the juicing shell 604 and is coaxially and fixedly connected to the juicing rod 605 with spiral blades, thereby constructing a bottom-up drive structure with an extremely low center of gravity and completely preventing juice leakage.

[0049] As a preferred embodiment, in order to achieve absolute hygiene and leak-proof isolation in the non-working state, a dust cover 608 is slidably connected to the outside of the juice outlet pipe 607 connected to the lower side of the juicing shell 604; and at the cup-collecting opening 301, in accordance with the rotation trajectory of the door stop base plate 712, when the connecting frame 702 leaves the cup-collecting opening 301 position and the juice receiving transmission gear 711 disengages, the protective door 713 automatically closes and locks under the pre-tightening force of the torsion spring 714, thereby cutting off the contact between the external environment and the inner chamber of the equipment.

[0050] Working principle:

[0051] When a user places a purchase order through the appliance cabinet 202, the reduction gearbox 401 located on the side of the fruit storage rack 4 is activated. The transmission rod 402 drives the power gear 403 to rotate. The power gear 403 drives the chain 405 to rotate in a cycle with the driven gear 404. The chain 405 drives the fruit channel 406 to move, smoothly pushing the fruit channel 406 containing the ordered fruit to be level with the fruit grabbing module 5. At this time, the fruit grabbing module 5 activates the vacuum suction cup to grab the fruit and transport it to the peeling module 501 to peel the fruit. The pure fruit pulp then falls into the juicing shell 604 in the juicing box 6. At this time, the juicing servo motor 601 located at the bottom is activated. Through the meshing of the juicing transmission gear 602 and the juicing driven gear 603, it drives the juicing rod 605 to rotate at high speed from bottom to top. The fruit pulp is strongly squeezed by the spiral blades, and the juice flows through the filter box 606 to the juice outlet pipe 607 to start discharging.

[0052] When the user places a purchase order, the brushless motor 8 starts and drives the cup dispensing power gear 801 to rotate. This power is transmitted to the cup dispensing driven gear ring 802, and using the planetary gear transmission principle, it drives multiple circumferentially distributed threaded cup dispensing rings 803 to rotate synchronously. The spiral surfaces of the multiple threaded cup dispensing rings 803 act on the rim of the cup at the same time, so that the bottom empty cup is evenly and smoothly peeled off and accurately falls into the cup holder 704 supported by the juice receiving frame 7.

[0053] After the cup is placed in the juice container, the juice receiving servo motor 701 starts, driving the connecting frame 702, which is suspended by the cup holder 704, to swing horizontally to the juice receiving station. Upon reaching the station, the sector-shaped power gear 703, coaxially fixed to the connecting frame 702, precisely engages with the sector-shaped driven gear 705 on the frame. The displacement energy from the continued swing is converted into the rotation of the sector-shaped driven gear 705, driving the linkage rod 706 to rotate. The rocker arm at its top then pulls the spring reciprocating rod 707, causing it to slide linearly within the guide. The spring reciprocating rod 707 pulls the rotation... The rotating rod 708 flips, which in turn forces the juice-receiving tipping bucket 709 to flip downwards and accurately align itself directly above the juice cup opening to receive the juice from the juice outlet pipe 607. When the weighing sensor fixed at the bottom of the cup holder 704 reaches the preset weight, the juicing stops. At this time, the servo motor 701 starts and drives the connecting frame 702 and the cup holder 704 to the capping position. The entire process is purely mechanically triggered, effectively preventing juice splashing. After the juice is collected, the juice-receiving servo motor 701 reverses, the gears disengage, and the juice-receiving tipping bucket 709 quickly resets under the action of the spring to prevent dripping.

[0054] After the juice is collected, the connecting frame 702 swings to the capping station. At this time, the brushless motor 8 starts again and outputs power downwards. Through the capping transmission rod 805 on the capping connecting plate 804, the capping driven gear ring 806 is driven to rotate. The internal gear ring drives all the capping driven gears 807 to rotate synchronously, so that the capping threaded rod 808 and the capping threaded rod 809 at the bottom rotate downwards synchronously. Under the control of this planetary gear system, the edge of the cup lid is subjected to a downward pushing force that is evenly distributed at multiple points. It falls off smoothly and is tightly pressed onto the juice cup, completely eliminating the problems of cap jamming and poor sealing caused by unilateral tilting.

[0055] After the capping is completed, the juice receiving servo motor 701 starts for the last time, driving the connecting frame 702 to swing the finished juice to the cup-taking station on the main cabinet door 3. Before reaching the cup-taking station, the sector-shaped power gear 703 on the connecting frame 702 accurately engages with the juice receiving driven gear 710. The juice receiving driven gear 710 transmits power to the juice receiving transmission gear 711, which in turn forces the door stop bottom plate 712 to rotate horizontally in a sector shape. The edge of the door stop bottom plate 712 directly presses against the lower edge of the protective door 713, overcoming the preload of the torsion spring 714, and physically pushes the protective door 713 outward to expose the cup-taking opening 301.

[0056] Users can also observe the internal situation through the inspection port 302 and take a straw from the straw port 201 of the electrical door 2. After the user takes away the juice cup, the juice receiving servo motor 701 drives the connecting bracket 702 to return to its position, the sector power gear 703 disengages, the door stop bottom plate 712 loses its support and releases its obstruction, and the protective door 713 automatically closes and locks under the action of the torsion spring 714, completely isolating external pollution and waiting for the next purchase order.
