DETAILED DESCRIPTION

[0032] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0033] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0035] In the packaging of yogurt cups, the process of attaching the lid to the yogurt cup is crucial. Early packaging practices involved manual capping, which was inefficient and labor-intensive. Later, linear cup and lid capping equipment was developed. This linear conveyor system automatically loaded, capped, and unloaded the cups. However, this system still suffered from low efficiency, typically only achieving a production capacity of 8,000 cups per hour.

[0036] In order to overcome the above technical problems, this embodiment provides a rotary cover-locking device to automatically lock the lid on the cup. The finished product after locking the lid can be referred to Figure 9 The structure shown.

[0037] Reference Figure 1-3 The rotary capping device of this embodiment includes a rotary capping unit 2, a cap feeding unit 4 and a cup feeding unit 3. The rotary capping unit 2 is a circular rotary structure, and its periphery is provided with a cup taking position, a cap taking position and a capping position. The cap feeding unit 4 can transport the caps one by one to the cap taking position, and the cup feeding unit 3 can transport the caps one by one to the cup taking position. The rotary capping unit 2 can automatically combine the caps and cup caps taken out from the cap taking position and the cup taking position together.

[0038] In the specific structure of the rotary cover-fastening device of this embodiment, the rotary cover-fastening unit 2 includes a cover-taking mechanism 21, a cup-taking mechanism 22 and a rotary drive mechanism 25. The cover-taking mechanism 21 is located above the cup-taking mechanism 22. The rotary drive mechanism 25 transmits and connects the cover-taking mechanism 21 and the cup-taking mechanism 22 to rotate simultaneously, so that the cover-taking mechanism 21 takes the cover at the cover-taking position, the cup-taking mechanism 22 takes the cup at the cup-taking position, and the cover-taking mechanism 21 fastens the cover on the cup at the cover-fastening position; the cover-feeding unit 4 extends to the cover-feeding position, for conveying the cover to the cover-feeding position; the cup-feeding unit 3 extends to the cup-taking position, for conveying the cup to the cup-taking position.

[0039] Specifically, the lid removing mechanism 21 and the cup removing mechanism 22 are arranged up and down. Under the drive of the rotary drive mechanism 25, the lid removing mechanism 21 rotates, and when it rotates to the lid removing position, it grabs the lid downward; the cup removing mechanism 22 rotates, and when it rotates to the cup removing position, it lifts the cup upward. When the cup and the lid are rotated to the lid buckling position at the same time, the lid removing mechanism 21 and the cup removing mechanism 22 move toward each other to buckle the lid onto the cup.

[0040] In summary, the rotary capping equipment based on this embodiment includes a cap feeding unit 4, a cup feeding unit 3 and a rotary capping unit 2. The rotary capping unit 2 adopts a rotary cycle structure of taking caps, taking cups and capping, which can realize a fast cycle of capping operations. Compared with the traditional linear capping operation method, the rotary capping equipment of this scheme can achieve an output of 20,000 cups per hour, which has the beneficial effect of greatly improving production efficiency.

[0041] Optional, to facilitate the collaborative work of each work unit, refer to Figure 1 The rotary cover-fastening device of this embodiment further includes a device base 1 , and each working unit is respectively installed on the device base 1 .

[0042] In one embodiment, referring to Figure 3 , and also includes an accessory delivery unit 5. A accessory removal position is provided on one side of the cover snapping unit and is located in front of the cover snapping position. The accessory delivery unit 5 extends to the accessory removal position and is used to deliver the accessories to the accessory removal position; when the cover removal mechanism 21 rotates to the accessory removal position, the accessories on the accessory delivery unit are just dropped onto the cup.

[0043] Specifically, the packaging structure of the cup and cup lid combination of this embodiment is generally used to package food, such as yogurt, ice cream, etc., and is usually equipped with accessories that facilitate users to eat food, such as spoons, straws, etc. In traditional solutions, accessories are generally attached to the side of the cup by dispensing glue.

[0044] This embodiment is provided with an accessory delivery unit 5, and a accessory retrieval position is provided in front of the lid-attaching position on the rotating lid-attaching unit 2. The accessory delivery unit 5 can automatically deliver accessories one by one to the accessory retrieval position. Before the lid is attached, the rotation of the lid-attaching mechanism 21 can be used to precisely remove the accessories from the accessory retrieval position, causing the accessories to fall onto the cup held by the cup-attaching mechanism 22 below. The lid is then attached to the cup, and the accessories are then precisely secured between the lid and the cup. Therefore, based on the solution of this embodiment, the function of automatically packaging accessories can be realized. More importantly, the accessories can be automatically attached to the lid without the need for glue fixation, which not only saves consumables, but also realizes concealed packaging of accessories, optimizes the product appearance, and reduces the risk of accessories falling.

[0045] In one embodiment, the rotary cover-fastening unit 2 further includes a first lifting guide plate 23 and a second lifting guide plate 24, which are arranged up and down; the cover-taking mechanism 21 includes a lifting cover-taking device 211 and a cover-taking rotating disk 212, the lifting cover-taking device 211 can be lifted and installed on the cover-taking rotating disk 212, the cover-taking rotating disk 212 is transmission-connected to the rotary drive mechanism 25, a first guide rail 231 is provided on the periphery of the first lifting guide plate 23, the lifting cover-taking device 211 is slidingly connected to the first guide rail 231, and the cover-taking rotating disk 212 is driven to rotate by the rotary drive mechanism 25, thereby pushing the lifting cover-taking device 211 around The first lifting guide plate 23 rotates and is lifted and lowered relative to the first lifting guide plate 23; the cup picking mechanism 22 includes a lifting cup picker 221 and a cup picking rotating plate 222. The lifting cup picker 221 can be lifted and lowered on the cup picking rotating plate 222. The cup picking rotating plate 222 is transmission-connected to the rotation drive mechanism 25. A second guide rail 241 is provided around the second lifting guide plate 24. The lifting cup picker 221 is slidingly connected to the second guide rail 241. The cup picking rotating plate 222 is driven to rotate by the rotation drive mechanism 25, thereby pushing the lifting cup picker 221 to rotate around the second lifting guide plate 24 and lift and lower relative to the second lifting guide plate 24.

[0046] Specifically, the lid removing mechanism 21 and the cup removing mechanism 22 are arranged up and down. In order to enable the lid removing mechanism 21 and the cup removing mechanism 22 to perform actions such as removing the lid, cup and buckling the lid at different positions during the rotation process, it is necessary for the lid removing mechanism 21 and the cup removing mechanism 22 to be able to move up and down relatively during operation.

[0047] The specific structure of the cap removal mechanism 21 is provided with a lifting cap removal device 211 and a cap removal rotating disk 212. A plurality of lifting cap removal devices 211 are arranged around the cap removal rotating disk 212, which can be freely raised and lowered. The cap removal rotating disk 212 is in transmission connection with a rotary drive mechanism 25. Therefore, when the rotary drive mechanism 25 drives the entire cap removal rotating disk 212 to rotate, the cap removal rotating disk 212 will drive all the lifting cap removal devices 211 installed thereon to rotate synchronously, achieving the purpose of transferring the cap removal devices 211 to the capping position after the lifting cap removal devices 211 remove the cap. In addition, the cap removal mechanism 21 is provided with a first lifting guide disk 23 with a first guide rail 231. The first lifting guide disk 23 is fixed, and the lifting cap removal devices 211 are slidably connected to the first guide rail 231. The first guide rail 231 is specifically a track with different heights at different positions. Therefore, when the lifting cap removal devices 211 rotate around the first lifting guide disk 23, the lifting cap removal devices 211 automatically rise and fall under the guidance of the first guide rail 231. During operation, when removing a lid, the lid is located below the lifting lid remover 211. Therefore, when in the lid removal position, the lifting lid remover 211 needs to gradually descend. After taking the lid, the lifting lid remover 211 reverses and ascends. When rotating to the lid attaching position, the lifting lid remover 211 needs to gradually descend. After attaching the lid to the cup, the lifting lid remover 211 reverses and ascends to release the attached lid. Therefore, the specific configuration of the first guide rail 231 can be corresponding to the lifting trajectory of the aforementioned lifting lid remover 211.

[0048] Similarly, the cup-removing mechanism 22 comprises a cup-lifting device 221 and a cup-removing rotating disk 222. Multiple cup-lifting devices 221 are positioned around the cup-removing rotating disk 222, allowing for their elevation. The cup-removing rotating disk 222 is in transmission connection with a rotary drive mechanism 25. Therefore, when the rotary drive mechanism 25 drives the entire cup-removing rotating disk 222 to rotate, the rotating disk 222 drives all of the cup-lifting devices 221 mounted thereon to rotate synchronously, achieving the purpose of transferring the cups removed by the cup-lifting devices 221 to the capping position. Furthermore, the cup-removing mechanism 22 is provided with a second lifting guide disk 24 with a second guide rail 241. The second lifting guide disk 24 is fixed, and the cup-lifting devices 221 are slidably connected to the second guide rail 241. The second guide rail 241 is specifically a track with varying heights at different locations. Therefore, as the cup-lifting devices 221 rotate around the second lifting guide disk 24, they automatically rise and fall under the guidance of the second guide rail 241. During operation, when removing a cup, the cup is located above the cup lifter 221. Therefore, when in the cup removal position, the cup lifter 221 needs to gradually descend. After taking the cup, the cup lifter 221 reverses its upward movement to lift the cup. When rotating to the cup-locking position, the cup lifter 221 needs to gradually ascend. After locking the lid and cup, the cup lifter 221 reverses its downward movement to allow the cup with the lid locked to be removed. Therefore, the specific configuration of the second guide rail 241 can be based on the aforementioned lifting trajectory of the cup lifter 221.

[0049] In this solution, the rotating and lifting mechanism simultaneously rotates and lifts an object. This combined motion significantly improves the efficiency of capping. In automated packaging and assembly lines, this structure can significantly reduce operational steps and time, accelerating production. By enabling multiple motion modes, including rotation and lifting, within the same space, this solution effectively reduces production line floor space. This is particularly important in space-constrained factory environments, improving space utilization and production efficiency.

[0050] In one embodiment, referring to Figure 6 The lifting and removing cover device 211 includes a first lifting shaft 2111, a first guide wheel 2112, a cover removing suction cup 2113 and a control air circuit 2114. The first guide wheel 2112 is rotatably mounted on the first guide rail 231; the upper and lower ends of the first lifting shaft 2111 are respectively connected to the first guide wheel 2112 and the cover removing suction cup 2113, and the control air circuit 2114 is connected to the cover removing suction cup 2113, which includes an air suction pipeline 21141 and an air blowing pipeline 21142. The air in the suction cup is sucked through the air suction pipeline 21141 so that the suction cup can suck the cover tightly, and the air is blown into the suction cup through the air blowing pipeline 21142 so that the suction cup can release the cover.

[0051] The first guide wheel 2112 is arranged to be rollingly mounted on the first guide rail 231, ensuring the stability and precise positioning of the lifting cover remover 211 during the rotation process. This guiding method not only reduces friction and wear, but also improves the accuracy and reliability of cover removal.

[0052] The cap-removing suction cup 2113 achieves the function of sucking and releasing the cap by controlling the air circuit 2114. When removing the cap at the cap-removing position, when the cap-removing suction cup 2113 descends to a position close to the cap, the suction line 21141 is synchronously activated to draw air from the suction cup, causing the suction cup to generate negative pressure and thus firmly hold the cap. After the cap is attached at the cap-attaching position, when the cap-removing suction cup 2113 begins to rise in the opposite direction, the air blowing line 21142 blows air into the suction cup, breaking the negative pressure and causing the suction cup to release the cap. This design makes the cap-removing process more flexible and controllable. The design of the control air circuit 2114 allows the operation of the cap-removing suction cup 2113 to be achieved through simple air circuit control, making it easy to integrate with the entire automated production line. At the same time, the air circuit control has the advantages of fast response speed and high control accuracy, which can meet the needs of high-speed and high-precision production.

[0053] In one embodiment, the lid removing rotating disk 212 includes a rotating disk body 2121 and a plurality of guide cylinders 2122 circumferentially arranged on the rotating disk body 2121, and the side walls of the guide cylinders 2122 are provided with avoidance openings; a lifting piston 2115 is installed in the middle of the first lifting shaft 2111, and the lifting piston 2115 is slidably installed in the guide cylinder 2122; the control air path 2114 is connected to the side of the lifting piston 2115 corresponding to the avoidance opening.

[0054] The guide cylinder 2122 and the lifting piston 2115 structure that cooperate with each other provide stable guidance and support for the first lifting shaft 2111, ensuring the stability and accuracy of the lifting cover remover 211 during rotation and reducing the failure of removing the cover due to shaking or offset. At the same time, the control air circuit 2114 is connected to one side of the lifting piston 2115. The lifting piston 2115 can provide a larger connection space for connecting the air pipe connector of the control air circuit 2114, ensuring the reliability of the connection of the control air circuit 2114. A clearance opening is provided on one side of the guide cylinder 2122 to avoid the connection of the control air circuit 2114, avoiding the problem of interference between the control air circuit 2114 and the guide cylinder 2122 during the lifting process, ensuring the stability and smoothness of the lifting process of the lifting cover remover 211. In order to control the air pressure in the cap removal suction cup 2113 through the control air circuit 2114 , an air duct that can connect the control air circuit 2114 and the inner cavity of the cap removal suction cup 2113 needs to be provided in the lifting piston 2115 and the first lifting shaft 2111 .

[0055] In one embodiment, the cup-lifting device 221 includes a second lifting shaft 2212, a second guide wheel 2213 and a cup-loading sleeve 2211. The second guide wheel 2213 is rotatably mounted on the second guide rail 241. The upper and lower ends of the second lifting shaft 2212 are respectively connected to the cup-loading sleeve 2211 and the second guide wheel 2213. The cup-taking rotating disk 222 includes a first turntable 2221 and a second turntable 2222 spaced apart in an upper and lower manner. The first turntable 2221 is provided with a guide hole that matches the outer circle of the cup-loading sleeve 2211, and the cup-loading sleeve 2211 passes through the guide hole. The second turntable 2222 is provided with a linear bearing 2223 that matches the second lifting shaft 2212, and the second lifting shaft 2212 passes through the linear bearing 2223.

[0056] The cup loading sleeve 2211 is used to load and secure cups. The outer circumference of the sleeve cooperates with the guide hole on the first turntable 2221 to ensure that the sleeve 2211 maintains the correct position and direction during the up and down movement. At the same time, the interior of the sleeve 2211 can be designed with a groove that matches the shape of the cup to more firmly secure the cup.

[0057] When the cup-lifting device 221 rotates to the cup-removing position, the cup-loading sleeve 2211 just drops below the upper edge and the upper surface of the first turntable 2221, allowing the cup to be easily pushed and dropped into the cup-loading sleeve 2211. As the first turntable 2221 continues to rotate, the cup-loading sleeve 2211 gradually rises, and the cup in the cup-loading sleeve 2211 rises accordingly, waiting for the completion of subsequent processes such as placing accessories and fastening the lid.

[0058] In one embodiment, referring to Figure 6 , also includes an accessory slitting unit 6 for slitting accessories, the accessory slitting unit 6 has an accessory support plate 61 extending to the accessory taking position, and the accessory support plate is provided with a long hole; the accessory delivery unit 5 includes a pulley bracket 51, a conveyor belt assembly 52, a conveying motor 54 and an accessory pushing rack 53, the conveyor belt assembly 52 includes a belt body 522 and two pulleys 521, the two pulleys 521 are respectively rotatably mounted on the pulley bracket 51, and the axes of the two pulleys 521 extend in the up and down directions, the belt body 522 is sleeved on the two In addition to the pulley 521, the conveying motor 54 is connected to one of the pulleys 521 to drive the belt body 522 to operate; the belt body 522 is circumferentially installed with multiple accessory pushing racks 53, and the accessory pushing rack 53 is provided with a push pin 56 that can pass through the long hole from bottom to top and slide along the long hole. The accessory pushing rack 53 is driven by the belt body 522 to flow between the accessory cutting unit 6 and the accessory retrieval position, so that the accessories on the accessory pallet are pushed to the accessory retrieval position one by one by using the push pin 56.

[0059] Specifically, refer to Figure 10 Existing accessories generally have independent outer packaging films. Since the packaging films are connected in a strip-like structure, existing accessories are generally strip-shaped. To facilitate the distribution of accessories to each cup one by one, the accessory cutting unit 6 is provided to precisely cut the outer packaging films between each accessory. After cutting, the accessories are then placed one by one on the accessory delivery unit 5 for conveyance to the rotary capping unit 2. The accessory cutting unit 6 is already existing and can be directly applied to this embodiment by combining existing technologies.

[0060] During operation, the accessory slitting unit 6 cuts the connected strip of accessories according to preset rules, separating the individual accessories. The separated accessories then fall one by one onto the accessory tray 61, where each accessory is caught by the push pin 56 of the accessory push rack 53 below. The conveyor motor 54 drives the conveyor belt assembly 52, which drives the accessory push rack 53 between the accessory slitting unit 6 and the accessory removal position. The push pins 56 push the accessories one by one to the accessory removal position. When the accessory push rack 53 reaches the accessory removal position, the cap removal mechanism 21 removes the accessories from the tray and dispenses them into the corresponding cups.

[0061] Specific, combined Figure 6 When in the accessory removal position, the lifting lid remover 211 located above the accessory push rack 53 is already covered with a lid. At this point, the lid's height is just enough to interfere with the accessories on the accessory tray 61. Therefore, the continued rotation of the lid can move the accessories on the accessory tray 61, allowing them to drop directly onto the cups below, thus completing the process of removing the accessories from the accessory tray 61. Therefore, this solution eliminates the need for a separate mechanism to remove the dispensed items one by one and distribute them to the cups. This solution can be achieved directly using the operating lid, resulting in a simple structure, low cost, and high reliability.

[0062] In one embodiment, the accessory pushing rack 53 includes a mounting seat 531, a bracket body 532 and a third guide wheel. The mounting seat 531 is fixed to the belt body 522, and the bracket body 532 is slidably mounted on the mounting seat 531. The push pin 56 is arranged on the bracket body 532, so that the bracket body 532 can drive the push pin 56 to slide up and down relative to the belt body 522, and the third guide wheel is connected to the bracket body 532; the accessory delivery unit 5 also includes a lifting guide plate 55, which is mounted on the side of the pulley bracket 51 close to the accessory support plate 61. The lifting guide plate 55 is provided with a guide groove 551, which is high in the middle and low at both ends, and the guide groove 551 extends downwardly at an angle corresponding to the accessory removal position. The third guide wheel can roll into the guide groove 551, so that when the cover removal mechanism 21 removes the accessory, the push pin 56 falls below the upper surface of the accessory support plate 61.

[0063] The guide slot 551 is provided on the lifting guide plate 55 so that the accessory pushing rack 53 can gradually rise along the guide slot 551 when it starts to enter the bottom of the accessory tray 61, so that the push pin 56 can gradually pass through the long hole on the accessory tray 61 from bottom to top, avoiding the problem of interference and collision between the push pin 56 and the structure of the accessory cutting unit 6 located above the front end of the accessory tray 61. The push pin 56 after passing through the long hole can smoothly push the accessory located on the accessory tray 61; in addition, when the push pin 56 pushes the accessory to the end of the accessory tray 61 (corresponding to the accessory taking position), the accessory pushing rack 53 gradually descends under the guidance of the guide slot 551. At this time, the push pin 56 gradually falls down and falls out of the long hole. At this time, the lid close to the top of the accessory tray 61 can just smoothly push the accessory to fall onto the cup. Since the push pin 56 has fallen in advance, the problem of collision and friction between the lid and the push pin 56 can be avoided.

[0064] In one embodiment, the lid feeding unit 4 includes a lid feeding conveyor belt 41 and a lid entering star wheel 42. One end of the lid feeding conveyor belt 41 is connected to the lid entering star wheel 42, and the lids are pushed one by one to the lid removal position at equal distances through the lid entering star wheel 42; the cup feeding unit 3 includes a cup feeding conveyor belt 31 and a cup entering star wheel 32. One end of the cup feeding conveyor belt 31 is connected to the cup entering star wheel 32, and the cups are pushed one by one to the cup removal position at equal distances through the cup entering star wheel 32.

[0065] The cap feeding unit 4 is primarily composed of a cap feeding conveyor belt 41 and a cap loading star wheel 42. The cap feeding conveyor belt 41 is responsible for transporting a large number of caps from the storage or supply area to a location closer to the cap removal position, while the cap loading star wheel 42 is located at the end of the cap feeding conveyor belt 41 and is responsible for pushing the caps on the conveyor belt to the cap removal position one by one at equal distances. Specifically, the cap loading star wheel 42 has multiple evenly distributed grooves or protrusions that match the shape of the caps, ensuring that each cap is stably grasped and pushed to the cap removal position at equal distances. In this way, the cap feeding unit 4 can continuously provide accurate caps for the subsequent assembly process.

[0066] The cup delivery unit 3 is similar to the lid delivery unit 4 and also includes a cup delivery conveyor belt 31 and a cup receiving star wheel 32. The cup delivery conveyor belt 31 is responsible for transporting cups from the storage or supply area to a location closer to the cup retrieval position, while the cup receiving star wheel 32 is located at the end of the cup delivery conveyor belt 31 and is responsible for pushing the cups on the conveyor belt to the cup retrieval position one by one at an equal distance.

[0067] Through the precise control of the lid-entering star wheel 42 and the cup-entering star wheel 32, it can be ensured that the lid and the cup are pushed to the lid-removing position and the cup-removing position equidistantly and accurately, thereby reducing errors and waste in the assembly process.

[0068] Specific, combined Figure 4 and 5 The lid-entry star wheel 42 and the cup-entry star wheel 32 are each connected to a drive shaft below. The drive shaft has a fixed operating speed and can maintain a uniform speed to push the lids and cups one by one into the rotary lid-locking unit 2. To achieve precise coordination between the various devices, the lid-entry star wheel 42, the cup-entry star wheel 32, and the rotary lid-locking unit 2 use the same rotation drive mechanism 25. The lid rotation drive mechanism 25 includes a synchronous belt and multiple synchronous wheels. The lid-entry star wheel 42, the cup-entry star wheel 32, and the rotary lid-locking unit 2 are each connected to a synchronous wheel. The synchronous belt passes around each synchronous wheel at the same time, driving the multiple synchronous wheels to rotate synchronously. Through the cooperation of the synchronous belt and the synchronous wheel, the lid-entry star wheel 42, the cup-entry star wheel 32, and the rotary lid-locking unit 2 can achieve synchronous rotation. This synchronization ensures that the lids and cups can accurately match the rotation cycle of the rotary lid-locking unit 2 during the pushing process, thereby avoiding problems such as misalignment or collision.

[0069] In one embodiment, a cup discharging unit 7 is further included, and the cup discharging unit 7 includes a cup discharging star wheel 72 and a cup discharging conveyor belt 71. The cup discharging unit 7 is arranged near the cup discharging position of the rotating cover unit 2, and the cup is pushed from the cup discharging position to the cup discharging conveyor belt 71 by the cup discharging star wheel 72.

[0070] After the cups are capped in the rotary capping unit 2, they rotate to the cup discharge position. The grooves or protrusions of the running cup discharge star wheel 72 accurately grasp the cups. As the star wheel 72 rotates, the cups are pushed one by one, evenly spaced, onto the cup discharge conveyor belt 71. Once a cup is placed on the cup discharge conveyor belt 71, it transports it at a constant speed to the designated position. This position is generally the starting point for the next production step.

[0071] Preferably, the cup discharge conveyor 71 and the cup inlet conveyor are located on the same straight line, so that the cup discharge conveyor 71 and the cup inlet conveyor 71 can use the same conveyor belt, which simplifies the structure and reduces costs. Similarly, the drive of the cup discharge star wheel 72 can also be driven by a rotary drive structure.
