Description

Technical Field

[0001] This utility model relates to the field of beverage preparation equipment technology, and in particular to an automatic cup-dropping device. Background Technology

[0002] With the fast pace of life, consumers' demands for freshly made beverages have shifted from simple convenience to a combination of high quality and efficiency. Against this backdrop, a new type of pre-packaged tea paper cup has emerged on the market. This tea paper cup has tea leaves pre-sealed at the bottom and separated from the upper part of the cup by a permeable filter membrane. When hot water is poured in, the water can pass through the filter membrane to fully contact the tea leaves for brewing, while the filter membrane effectively prevents tea leaves from entering the mouth, thus balancing the excellent taste of whole-leaf tea with the convenience of tea bags.

[0003] However, existing technologies lack a dedicated device capable of storing, separating, and dropping pre-placed tea paper cups, and then completing the subsequent water pouring and brewing process. More specifically, existing technologies face significant bottlenecks in the crucial step of automatically separating and dropping the cups. Common cup-dropping mechanisms, such as those using grippers, while achieving a degree of automation, often suffer from reliability issues: when cups stick together due to overly tight stacking, static electricity, or slight deformation, these mechanisms struggle to reliably separate only the bottom cup, frequently resulting in multiple cups dropping at once ("multiple cup drops") or none dropping at all ("cup jamming"), severely impacting the stable operation of the equipment.

[0004] Therefore, developing an automatic cup-dropping device that is simple in structure, reliable in operation, and capable of efficiently and stably separating stacked cups one by one has become an urgent technical problem to be solved in this field. Utility Model Content

[0005] The main purpose of this invention is to provide an automatic cup-dropping device to solve the above-mentioned technical problems.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] An automatic cup-dropping device, suitable for stacked cups, includes a plurality of synchronously rotatable separating cams. Each separating cam includes a cam portion and a gear portion connected to each other. The cam portion has a continuous profile configured such that, when rotated to a first angular position, it supports the bottom cup in the stacked cups; and during rotation from the first angular position to a second angular position, the separating cam drives the bottom cup downwards while simultaneously supporting a cup immediately above the bottom cup, so that the bottom cup is separated from the stacked cups and falls to a predetermined position.

[0008] The plurality of separation cams are arranged circumferentially around the lower part of the stacked cups, and each separation cam is configured to rotate about its respective axis.

[0009] The cam portion has a first support portion and a second support portion with opposite sides, and a transition support portion disposed between the first support portion and the second support portion; when the separating cam rotates to the first angle position, the first support portion supports the bottom cup in the stacked cups; during the process of the separating cam rotating from the first angle position to the second angle position, the first support portion disengages from the bottom cup, and the second support portion supports the cup above the bottom cup; the transition support portion drives the bottom cup downward.

[0010] It also includes a first drive assembly, which includes a first drive motor and a transmission mechanism connected to the first drive motor, the transmission mechanism meshing with the gear portion of each of the separating cams.

[0011] The transmission mechanism includes a linkage gear disk with an internal gear ring, and the gear portions of the plurality of separating cams mesh with the internal gear ring of the linkage gear disk; the transmission mechanism also includes a drive gear connected to the first drive motor, and a driven gear meshing with both the drive gear and the linkage gear disk.

[0012] The device also includes a base and a top cover disposed on the base. A cavity is formed between the base and the top cover. A plurality of separation cams are disposed in the cavity. An opening is provided at the top and bottom of the cavity. A channel formed between the openings is used to accommodate a material cylinder and the stacked cups inside the material cylinder.

[0013] The base has a through hole on its bottom surface. The output shaft of the first drive motor passes through the through hole and is fixedly connected to a mounting component. The mounting component includes a connecting rod and a first drive arm disposed at the top of the connecting rod. The connecting rod passes through the middle of the drive gear, so that the first drive arm can be accommodated in a groove on the top surface of the drive gear.

[0014] The system also includes a sealing assembly disposed below the base, with a first seal provided at the bottom of the channel; the sealing assembly includes a second seal and a second driving assembly, the second seal being adapted to the first seal to seal the channel when it is in contact with the first seal under the drive of the second driving assembly.

[0015] The second drive assembly includes a second drive motor, a second drive arm connected to the second drive motor, and a return spring. One end of the second drive arm is provided with a sliding member, on which the second sealing member is provided. The sliding member can move along a straight path between a sealed position and a non-sealed position. The second drive motor drives the second drive arm to rotate to abut against and push the sliding member, causing the sliding member to move to the non-sealed position against the elastic force of the return spring. When the second drive arm rotates to disengage from the sliding member, the sliding member returns to the sealed position under the drive of the return spring.

[0016] The sealing assembly further includes a sealing box body disposed below the base, the second driving assembly is disposed in the sealing box body, a support rail is disposed inside the sealing box body, and the sliding member slides in cooperation with the support rail.

[0017] The beneficial technical effects of this utility model are as follows:

[0018] This invention fundamentally solves the reliability problem caused by cup adhesion in the prior art through a synchronous and continuous action that integrates active separation and seamless support. Specifically, the solution uses multiple synchronously rotating separation cams. During rotation, the cams actively apply a downward driving force, forcibly separating the bottom cup from the stack, effectively overcoming the adhesion caused by static electricity or excessive stacking, thus solving the problem of "cup jamming." Simultaneously, while driving downwards, another part of the cam seamlessly switches into place, firmly supporting the cup immediately above, ensuring that the remaining cup stack remains stable at all times, thus preventing multiple cups from falling off. This combination of "active separation" and "seamless support" ultimately achieves efficient, stable, and reliable individual separation of stacked cups, significantly improving the operational stability of the equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0035] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0036] Please also refer to Figures 1-10 This utility model provides an automatic cup-dropping device suitable for separating multiple stackable cups one by one. The cups can be paper cups pre-filled with tea leaves, with an outwardly protruding rim at the mouth, providing a reliable point of contact for subsequent support and separation actions. The device includes multiple synchronously rotatable separation cams 310. Each separation cam 310 includes a connected cam portion 311 and a gear portion 315. The cam portion 311 has a continuous profile configured such that, when rotated to a first angular position, it supports the bottommost cup 201 in the stack; and during rotation from the first angular position to a second angular position, the separation cam 310 drives the bottommost cup 201 downwards while simultaneously supporting the cup immediately above it, causing the bottommost cup 201 to separate from the stack and fall to a predetermined position.

[0037] In this embodiment, each separating cam 310 structurally includes a cam portion 311 and a gear portion 315. The cam portion 311 and the gear portion 315 are interconnected and can be integrally formed or detachably connected. The cam portion 311 is located at the upper part of the separating cam 310, and its function is to directly interact with the cup body to achieve support, drive, and separation. The gear portion 315 is located at the lower part of the separating cam 310, and its function is to serve as a power input end, meshing with the transmission mechanism, receiving driving force, and ensuring that all separating cams 310 can rotate synchronously.

[0038] The cam portion 311 has a continuously varying profile, which is not a simple circle but a curve with specific functional sections. The function of this profile is manifested by the rotation of the disengaging cam 310, specifically configured as follows:

[0039] On one hand, the profile is configured such that when all the separating cams 310 rotate synchronously to a preset first angular position, a specific section of its cam portion 311 can stably support the bottommost cup 201 among the stacked cups. For example, this section of multiple separating cams 310 can simultaneously act below the outer edge of the rim of the bottommost cup 201, together forming a stable and reliable support platform. In this state, the entire stack of cups is reliably held within the device and will not fall accidentally; this is the standby or initial state of the device before or after performing the cup-dropping task.

[0040] On the other hand, the profile is also configured such that when the device needs to perform the cup-dropping action, all separating cams 310 rotate synchronously from the first angular position. During the rotation to a second angular position, different segments of the profile interact with the cup body in sequence, producing a series of coordinated actions. Specifically, during this rotation, the profile segment that originally supported the bottom cup body 201 gradually moves away, while another profile segment of the cam 311 drives the bottom cup body 201 downward (e.g., by pressing the upper surface of its outer edge), actively overcoming any friction between the cup bodies or the adhesive force caused by excessive stacking. While driving the bottom cup body 201 downward, another profile segment of the cam 311 rotates into position to support the cup body immediately above the bottom cup body 201, namely the upper cup body 202.

[0041] Through the seamless coordinated actions of "removing the old support, actively driving downwards, and establishing a new support," the bottom cup 201 is reliably separated from the stack of cups and falls to a predetermined position under gravity for subsequent use. Simultaneously, the remaining cups are stably supported, preparing for the next cup-dropping action.

[0042] In summary, this embodiment solves the technical problems of "cup jamming", "multiple cup dropping" and the contradiction between support and separation in traditional cup dropping mechanisms by designing multiple separation cams 310 with specific contours and synchronous rotation in a simple and reliable manner, and achieves stable and efficient one-by-one separation of stacked cups.

[0043] In one embodiment, a plurality of the separation cams 310 are arranged circumferentially around the lower part of the stacked cups, and each of the separation cams 310 is configured to rotate about its respective axis.

[0044] In this embodiment, these separating cams 310 are arranged around the lower outlet of the channel 140 (e.g., formed by the barrel 100) for receiving the cup, forming a circular array. This arrangement ensures that all separating cams 310 can simultaneously contact the outer edge of the bottom cup 201, thereby forming a stable platform with multi-point support during support and applying a uniform driving force during separation, effectively preventing the cup from tilting or getting stuck during the separation process.

[0045] In a preferred embodiment, three, four, or five separation cams 310 may be provided and evenly distributed circumferentially. The number of separation cams 310 can be adjusted according to the size and weight of the cup and the requirements for stability, but a circumferentially distributed arrangement is ideal for ensuring force balance and motion synchronization.

[0046] Furthermore, in order for the specific contours of the separating cams 310 to act on the cup body at a predetermined timing, each separating cam 310 is configured to rotate about its respective axis. This axis is the central axis perpendicular to the plane in which the separating cam 310 is located. It is through rotation about their respective axes that the contour segments with different functions on the cam portion 311 of each separating cam 310 can sequentially perform the functions of supporting the lower cup body, controlling the upper cup body 202, and pressing down on the bottom cup body 201 at specific angular positions during rotation.

[0047] A significant advantage of this design is its compact structure. Because each cam rotates in place, it occupies very little radial space, allowing the entire mechanism to be designed as a compact annular module, tightly mounted below the cup channel 140, without significantly increasing the overall size of the device.

[0048] In one embodiment, the cam portion 311 has a profile with opposing first support portion 312 and second support portion 313, and a transition support portion 314 disposed between the first support portion 312 and the second support portion 313; wherein, when the separating cam 310 rotates to the first angular position, the first support portion 312 supports the bottom cup 201 in the stacked cups, and during the process of the separating cam 310 rotating from the first angular position to the second angular position, the first support portion 312 disengages from the bottom cup 201, and the second support portion 313 supports the cup above the bottom cup 201, and the transition support portion 314 drives the bottom cup 201 downward.

[0049] In this embodiment, the continuous contour of the cam portion 311 can be functionally divided into three interconnected sections: a first support portion 312, a second support portion 313, and a transition support portion 314 disposed between them. These three sections work together to complete the support conversion and separation drive of the cup body during the rotation of the separation cam 310.

[0050] From a physical perspective, the first support portion 312 can be understood as a flat or gently curved surface at the bottom of the cam profile. Its main function is to support the cup body in the standby state of the device. When all the separating cams 310 rotate to the first angle position, their respective first support portions 312 will be located directly below the outer edge of the cup mouth of the bottommost cup body 201, forming a stable and reliable multi-point support platform to firmly support the entire stack of cups.

[0051] The second support 313 is a curved surface at the top of the cam profile. Its function is to extend into the gap between the bottom cup 201 and the adjacent upper cup 202 during the separation process, thereby taking over the support of the upper cup 202.

[0052] The transition support 314 is a curved section located in the middle, connecting the first support 312 and the second support 313, forming a ramp-like structure. Its function is to actively drive the bottom cup 201 downward while supporting the transition.

[0053] The following describes the collaborative workflow of these three parts using a complete separation action as an example:

[0054] When the separating cam 310 begins to rotate synchronously from the first angular position:

[0055] Release of support: As rotation continues, the first support 312 will gradually move away from below the mouth of the bottom cup body 201, thereby releasing its direct support.

[0056] Switching support: At the same time, the second support 313 rotates into position, its surface contacting the lower surface of the outer edge of the upper cup 202, and begins to support the upper cup 202 and all the cups above it. This seamless switching action ensures that the entire stack of cups above the bottom cup 201 will not become unstable and fall when the bottom cup 201 is released.

[0057] Active separation: During the aforementioned support switching process, the transition support 314, which has a ramp shape, also rotates. Its upper contour surface contacts and continues to support the upper cup 202, while its lower contour surface presses downward against the outer edge of the bottom cup 201. This downward pressure actively pushes the bottom cup 201 out of its nested state with the upper cup 202, effectively overcoming the adhesion that may be caused by friction or deformation between the cups.

[0058] As the separating cam 310 rotates to the second angle position, the bottom cup 201 is successfully driven downwards and separated, while the remaining cup stack is stably supported by the transition support 314. Next, the separating cam 310 does not stop but continues to rotate to complete a full cycle.

[0059] As the second angle position continues to rotate, since the transition support 314 is a downward slope, the stack of cups will slide down a short distance steadily and controllably along the slope under the action of gravity, smoothly descending from a higher position to a lower position.

[0060] Finally, the first support 312 rotates again to the bottom of the cup stack, catching it steadily at a lower position and restoring it to its initial stable supporting state (i.e., the first angle position), preparing for the next cup dropping action.

[0061] By dividing the cam profile into three functional sections and utilizing a complete rotation cycle, this device not only achieves reliable separation and seamless support switching, but also ensures that the entire cup stack remains stable throughout the cycle through a controlled downward sliding process, greatly improving the success rate and stability of cup dropping.

[0062] In this embodiment, the first support portion 312 and the second support portion 313 are opposite each other, meaning that one is located at a low point and the other at a high point on the contour of the cam portion 311. The end of the support provided by the first support portion 312 is the beginning of the support provided by the second support portion 313.

[0063] In one embodiment, the device further includes a first drive assembly, which includes a first drive motor 410 and a transmission mechanism connected to the first drive motor 410, the transmission mechanism engaging with a gear portion 315 of each of the separating cams 310.

[0064] In this embodiment, the first drive component includes a first drive motor 410 and a transmission mechanism connected to the first drive motor 410.

[0065] The first drive motor 410 serves as a power source, responsible for providing initial rotational power. In one feasible implementation, the first drive motor 410 can be a DC geared motor to provide stable power output with appropriate torque. Other types of motors can also be selected according to design requirements.

[0066] The transmission mechanism receives power from the first drive motor 410 and effectively transmits it to each separating cam 310. To achieve this function, the transmission mechanism is designed to mesh with the gear portion 315 of each separating cam 310.

[0067] Through this mechanical meshing connection, when the first drive motor 410 starts and drives the transmission mechanism, the transmission mechanism simultaneously drives the gear sections 315 of all the meshing separation cams 310 to rotate. Because it is a mechanical hard connection (meshing), it can be fundamentally guaranteed that all separation cams 310 can rotate synchronously with exactly the same angular velocity and phase.

[0068] This design, which uses a single first drive motor 410 in conjunction with a transmission mechanism to drive multiple separating cams 310, offers significant advantages compared to a separate drive source for each separating cam 310. It not only greatly simplifies the mechanical structure and control system, reducing manufacturing costs and potential failure points, but more importantly, it physically ensures the absolute synchronicity and consistency of the rotation of all separating cams 310 through mechanical engagement. This synchronicity is crucial for ensuring that the cup remains stable during the separation process, without tilting or jamming, thus guaranteeing successful separation and release.

[0069] In one embodiment, the transmission mechanism includes a linkage gear disk 423, which has an internal gear ring, and the gear portions 315 of the plurality of separating cams 310 mesh with the internal gear ring of the linkage gear disk 423; the transmission mechanism also includes a drive gear 421 connected to the first drive motor 410, and a driven gear 422 meshing with both the drive gear 421 and the linkage gear disk 423.

[0070] In this embodiment, the linkage gear disk 423 is a ring-shaped gear with an internal gear ring machined on its inner circumferential wall. In terms of assembly, the gear portions 315 of the multiple separating cams 310 mesh with the internal gear ring of the linkage gear disk 423. This arrangement, where multiple external gears (gear portions of the separating cams) mesh with a central internal gear (internal gear ring of the linkage gear disk), forms an internal meshing transmission structure similar to a planetary gear system. When the linkage gear disk 423 rotates, its internal gear ring acts as a unified driving source, simultaneously driving all meshing separating cams 310 to rotate around their respective axes with the same angular velocity and direction, thus achieving synchronized operation.

[0071] To drive the linkage gear 423 to rotate, the transmission mechanism also includes a driving gear 421 and a driven gear 422. The driving gear 421 is directly connected to the output shaft of the first drive motor 410, serving as the power input end of the entire transmission chain. When the first drive motor 410 starts, its rotational motion is directly transmitted to the driving gear 421.

[0072] The driven gear 422 serves as an intermediate transmission component, capable of simultaneously meshing with both the driving gear 421 and the linkage gear disk 423. Specifically, the external teeth of the driven gear 422 mesh with the external teeth of the driving gear 421, and simultaneously, its external teeth also mesh with the internal gear ring of the linkage gear disk 423.

[0073] The entire power transmission path is as follows: the first drive motor 410 starts and drives the drive gear 421 to rotate; the drive gear 421 drives the driven gear 422 to rotate in the opposite direction through external meshing; the driven gear 422 then drives the linkage gear disk 423 to rotate in the same direction through internal meshing; finally, the rotating linkage gear disk 423 drives all the disengaged cams 310 to rotate synchronously through its internal gear ring.

[0074] This transmission design, consisting of "driving gear 421 - driven gear 422 - linkage gear disc 423 (internal gear ring) - separating cam 310 (gear section)," is extremely compact and can achieve precise synchronous transmission of all separating cams 310 with a minimal number of parts. It efficiently transforms the single rotational input of the first drive motor 410 into perfectly synchronized rotational output from multiple separating cams 310, greatly ensuring the stability and reliability of the cup-dropping process.

[0075] In other embodiments, the transmission mechanism of the cup-dropping mechanism can also employ a synchronous belt (not shown in the figures) to achieve synchronous rotation among multiple separating cams 310. Specifically, the cup-dropping mechanism includes a first drive motor 410 and a driving synchronous pulley connected to the output shaft of the first drive motor 410. The gear portion 315 on each separating cam 310 for transmitting power is replaced by a driven synchronous pulley. The multiple driven synchronous pulleys are linked together by an annular synchronous belt. The driving synchronous pulley cooperates with the annular synchronous belt. Under the drive of the first drive motor 410, the driving synchronous pulley drives the annular synchronous belt to move, thereby driving the multiple driven synchronous pulleys to rotate synchronously, achieving synchronous rotation of the multiple separating cams 310.

[0076] In one embodiment, the system further includes a base 110 and a top cover 120 disposed on the base 110. A cavity 130 is formed between the base 110 and the top cover 120. A plurality of separation cams 310 are disposed in the cavity 130. An opening is provided at the top and bottom of the cavity 130. A channel 140 formed between the openings is used to accommodate the material cylinder 100 and the stacked cups inside the material cylinder 100.

[0077] In this embodiment, the upper cover 120 and the base 110 can be detachably connected by fasteners such as screws and clips to form a structural shell.

[0078] When the top cover 120 and the base 110 are assembled together, they together form an internal cavity 130. The aforementioned multiple separating cams 310 and the transmission mechanism for driving them are all housed and installed within this cavity 130. This design effectively supports, positions, and protects these moving parts. For example, the separating cams 310, the linkage gear 423, and the driven gear 422 are all rotatably connected to the base 110.

[0079] To allow the cup to pass smoothly through the device, the cavity 130 has an opening at both its top (top cover) and bottom (base). These two openings are aligned vertically and are interconnected, forming a vertical channel 140.

[0080] The function of the channel 140 is to accommodate the container 100 and the stacked cups within it. In practical applications, the container 100 for storing the stacked cups can be inserted from above and fixed to the opening of the top cover 120, allowing the entire stack of cups within the container 100 to pass through the channel 140. The outer edge of the rim of the bottommost cup 201 is located precisely inside the cavity 130, in a position corresponding to the action of the multiple separating cams 310. After the separation action is completed, the separated bottommost cup 201 falls from the opening of the base 110 into a predetermined position below.

[0081] In one embodiment, the bottom surface of the base 110 has a through hole 412, the output shaft of the first drive motor 410 passes through the through hole 412 and is fixedly connected to a mounting component. The mounting component includes a connecting rod 431 and a first drive arm 432 disposed at the top end of the connecting rod 431. The connecting rod 431 passes through the middle of the drive gear 421, so that the first drive arm 432 can be accommodated in the groove 4211 on the top surface of the drive gear 421.

[0082] In this embodiment, a through hole 412 is provided on the bottom surface of the base 110. The through hole 412 is located off-center to accommodate the layout of the transmission mechanism. The first drive motor 410 is mounted below the base 110, and its output shaft passes through the through hole 412 from bottom to top and extends into the cavity 130.

[0083] In order to reliably transmit the rotational power of the first drive motor 410 to the transmission mechanism (especially the drive gear) located in the cavity 130, a mounting piece is fixedly connected to the end of the output shaft of the first drive motor 410.

[0084] The mounting component includes a connecting rod 431 and a first drive arm 432 disposed at the top of the connecting rod 431. In this embodiment, the connecting rod 431 is vertically arranged and coaxially arranged with the motor output shaft; the first drive arm 432 is horizontally arranged at the top of the connecting rod 431, and can be one or more arm-shaped structures extending from the center.

[0085] During assembly, the connecting rod 431 of the mounting component passes through the middle of the drive gear 421. This means that the drive gear 421 is positioned vertically by the connecting rod 431. The key to power transmission is that the first drive arm 432 is designed to fit into a pre-set groove 4211 on the top surface of the drive gear 421. The shape of the groove 4211 matches the shape of the first drive arm 432, allowing the first drive arm 432 to snap into or embed itself within it.

[0086] Through this "first drive arm 432-slot 4211" connection, when the first drive motor 410 rotates, its output shaft drives the mounting component to rotate synchronously. The first drive arm 432 on the mounting component then actuates the side wall of the slot of the drive gear 421, thereby reliably transmitting the rotational torque of the motor to the drive gear 421, causing it to rotate and thus driving the entire transmission mechanism. This design eliminates the need for traditional key connections or interference fits, making installation and disassembly very simple, while ensuring the reliability of torque transmission.

[0087] In one embodiment, a sealing assembly is further included, which is disposed below the base 110, and a first sealing element 510 is disposed at the bottom of the channel 140; the sealing assembly includes a second sealing element 520 and a second driving assembly, the second sealing element 520 being adapted to the first sealing element 510 to seal the channel 140 when it is in contact with the first sealing element 510 under the drive of the second driving assembly.

[0088] In this embodiment, the sealing assembly is disposed entirely below the base 110, and its purpose is to selectively close the bottom outlet of the vertical channel 140 formed by the opening of the upper cover 120 and the base 110.

[0089] To achieve a seal, a first sealing element 510 is provided at the bottom of the channel 140, i.e., around the opening of the base 110. This first sealing element 510 can be an O-ring. It is fixed to the lower surface of the base 110, surrounding the opening of the channel 140.

[0090] The sealing assembly also includes a second seal 520 and a second drive assembly for actuating its movement. The second seal 520 is adapted in shape and size to the first seal 510. For example, if the first seal 510 is an annular sealing ring surrounding an opening, the second seal 520 can be a flat cover plate with a surface area sufficient to completely cover the first seal 510.

[0091] The second seal 520 is not stationary but can move under the drive of the second drive assembly. Its movement path is designed to allow it to switch between a "sealed position" and an "unsealed position." When the second drive assembly moves the second seal 520 to the sealed position, the second seal 520 fits tightly against the first seal 510, effectively sealing the bottom outlet of the channel 140. At this time, external dust, moisture, or other contaminants cannot enter the channel 140, and similarly, objects or the environment inside the channel 140 are isolated from the outside. When it is necessary to drop the cup, the second drive assembly drives the second seal 520 to move away, opening the outlet of the channel 140 and allowing the cup to fall smoothly.

[0092] In one specific embodiment, to achieve a more reliable sealing effect, the bottom of the channel 140 is designed as a slope, and the first sealing member 510 is correspondingly affixed to this slope. Correspondingly, the sealing surface of the second sealing member 520 is also sloped. When it is necessary to close the channel 140, the second drive assembly drives the second sealing member 520 to move horizontally, bringing it closer to the first sealing member 510. Since the contact surfaces of the base 110 where the first sealing member 510 is located and the second sealing member 520 are both matching slopes, when the second sealing member 520 moves horizontally, the two sloped surfaces will contact each other and generate a wedge-shaped locking effect, forming a highly airtight seal.

[0093] Conversely, when channel 140 needs to be opened, the second drive assembly drives the second seal 520 to move in the opposite direction horizontally, the two inclined surfaces separate, the seal is quickly released, and the outlet of channel 140 opens, allowing the cup to fall smoothly. This design, which utilizes inclined surfaces in conjunction with horizontal movement, can achieve a large sealing clamping force with a small driving force, thus improving the reliability of the seal.

[0094] In one embodiment, the second drive assembly includes a second drive motor 600, a second drive arm 620 connected to the second drive motor 600, and a return spring 632. One end of the second drive arm 620 is provided with a sliding member 630, on which the second sealing member 520 is provided. The sliding member 630 can move along a straight path between a sealed position and an unsealed position. The second drive motor 600 drives the second drive arm 620 to rotate to abut against and push the sliding member 630, causing the sliding member 630 to move to the unsealed position against the elastic force of the return spring 632. When the second drive arm 620 rotates to disengage from the sliding member 630, the sliding member 630 returns to the sealed position under the drive of the return spring 632.

[0095] In this embodiment, the second drive assembly includes a second drive motor 600, a second drive arm 620 connected to the motor, a slider 630, and a return spring 632. The second drive motor 600 can be a DC motor or a stepper motor, and its output shaft is fixedly connected to the second drive arm 620. The second drive motor 600 can drive the second drive arm 620 to rotate in both forward and reverse directions. One end of the second drive arm 620 (the end away from the motor shaft) is in rolling engagement with the slider 630. This "rolling engagement" can be specifically implemented by setting a pin at one end of the second drive arm 620 and installing a roller or bearing on the pin. The roller or bearing then engages with the slider 630. This design can significantly reduce the frictional force during relative movement, making the movement smoother. The slider 630 can move along a preset straight path. The second seal 520 is installed on the slider 630 and moves with it. The reset spring 632 is disposed on the moving path of the slider 630 and is used to apply a constant reset force to the slider 630 to move it toward the sealing position.

[0096] The entire component works as follows:

[0097] Opening process: When it is necessary to open channel 140, the second drive motor 600 starts and drives the second drive arm 620 to rotate forward. One end of the second drive arm 620 contacts and abuts the slider 630. As the second drive arm 620 continues to rotate, it pushes the slider 630 to overcome the elastic force of the return spring 632 and move it along a preset straight path to the unsealed position, thereby fully opening the outlet of channel 140. During this process, the return spring 632 is compressed, storing elastic potential energy, and continuously applies a tendency force to the slider 630 to return it to the sealed position.

[0098] Closing Process: When it is necessary to close channel 140, the second drive motor 600 rotates in the opposite direction, causing the second drive arm 620 to disengage from the sliding member 630. Once the obstruction of the second drive arm 620 is removed, the elastic potential energy stored in the return spring 632 is immediately released, driving the sliding member 630 to smoothly return to the initial sealing position along a straight path. At this time, the second sealing member 520 fixed thereon fits tightly with the first sealing member 510, achieving reliable closure of channel 140.

[0099] It is evident that the power to close the seal is entirely provided by the return spring 632, ensuring the constancy and reliability of the sealing force each time it closes. This effectively avoids problems such as incomplete or excessive sealing caused by fluctuations in motor torque or inaccurate control. The second drive motor 600 is only responsible for overcoming the spring force to push the sliding member 630 to the open position, and its load is predictable. During the closing process, it only needs to rotate to disengage from the contact, fundamentally avoiding the risk of the motor stalling, overloading, or even being damaged due to encountering obstacles.

[0100] In one embodiment, the sealing assembly further includes a sealing box 530 disposed below the base 110, the second driving assembly is disposed in the sealing box 530, a support rail 531 is disposed inside the sealing box 530, and the sliding member 630 is slidably engaged with the support rail 531.

[0101] In this embodiment, to effectively support, position, and protect the sealing assembly, the sealing assembly further includes a sealing housing 530. This sealing housing 530 is installed below the base 110 of the automatic cup-dropping device. The second drive motor 600, the second drive arm 620, and the return spring 632 are all disposed inside this sealing housing 530.

[0102] To ensure that the slider 630 can move precisely along a preset straight path, a support rail 531 is also provided inside the sealed box 530. The support rail 531 can be a groove machined on the inner wall of the box or an additionally installed linear guide rail.

[0103] The slider 630 is designed to slide in conjunction with the support rail 531. For example, flanges or sliders matching the support rail 531 can be provided on both sides of the slider 630. Through this cooperation between the rail and the slider 630, the movement freedom of the slider 630 is strictly limited to one direction, namely, a preset linear reciprocating motion path. This effectively prevents the slider 630 from deflecting, wobbling, or jamming during movement, thereby ensuring that the second sealing member 520 fixed on it can move smoothly and accurately to the predetermined sealing and non-sealing positions, ensuring the reliability and repeatability of each sealing and opening action.

[0104] In one embodiment, a first photoelectric sensor 700 and a second photoelectric sensor 800 are provided on the sealed box body 530, and a detection part 631 is provided at a corresponding position on the sliding member 630.

[0105] In this embodiment, a first photoelectric sensor 700 and a second photoelectric sensor 800 are respectively provided on the sealing box 530 near the two end positions of the sliding member 630 along the movement path of the sliding member 630. Correspondingly, a detection part 631 is provided on the sliding member 630, such as a light-blocking plate extending from the sliding member 630, which is designed to effectively trigger the photoelectric sensor.

[0106] When channel 140 needs to be opened, the second drive motor 600 drives the second drive arm 620, pushing the slider 630 to a non-sealed position. When the slider 630 moves to the end of its stroke, i.e., the non-sealed state, its detection part 631 is detected by the second photoelectric sensor 800. The second photoelectric sensor 800 generates a detection signal and feeds it back to the second drive motor 600, causing it to stop driving. This ensures that channel 140 is fully opened and prevents the motor from being overloaded or damaged due to continuous pushing. The detection signal can also be simultaneously fed back to the controller 10 to confirm that the channel is open, so that the controller can execute the next step (such as dropping a cup).

[0107] When channel 140 needs to be closed, the second drive motor 600 rotates in the reverse direction, causing the second drive arm 620 to disengage from the contact point. The sliding member 630, driven by the return spring 632, automatically moves towards the sealing position. When the sliding member 630 reaches the sealing position, its detection unit 631 enters the detection area of ​​the first photoelectric sensor 700. At this time, the first photoelectric sensor 700 is triggered and generates a "sealing in place" confirmation signal. This signal is fed back to the controller 10 to confirm that the channel has been reliably closed, allowing the controller to execute the next step (such as entering standby mode).

[0108] With this configuration, the device achieves complete closed-loop control of the sealing mechanism's movement. The second photoelectric sensor 800 serves as a limit switch for the opening action, while the first photoelectric sensor 700 acts as a status confirmation sensor for the closing action. This control method not only ensures the precise positioning of the sliding member at its two extreme positions but also improves the reliability and safety of the entire system's operation.

[0109] With this configuration, the second photoelectric sensor 800 can serve as a channel open status confirmation sensor, while the first photoelectric sensor 700 can serve as a channel closed status confirmation sensor. This approach not only ensures the positioning of the slider at its two extreme positions, preventing motor overload, but also significantly improves the reliability and safety of the entire system operation process by providing clear status feedback to the controller.

[0110] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
