Abstract
Description
Technical Field
[0001] This application relates to the field of beverage machinery technology, and in particular to a beverage machine capping device. Background Technology
[0002] Currently, automatic beverage machines are becoming increasingly common in the beverage industry. These machines can quickly prepare various drinks, such as coffee, milk tea, and juice. Before dispensing, self-service beverage machines perform a capping operation. Traditional capping devices use a flat surface to press down, providing more even pressure and helping to ensure a tight seal between the lid and the cup, preventing leakage.
[0003] However, this method also has some potential drawbacks. For example, if the pressing force is too great when pressing down the entire flat surface, it may cause the lid or cup to deform or even be damaged. If the force is too small, it may not be able to ensure a complete seal. In addition, existing beverage machine lid pressing devices are usually designed for regular-shaped and rigid lids. Different materials and shapes of lids may require different pressing methods. Flat pressing may not be suitable for all types of lids, especially those with irregular shapes or softer materials. Therefore, developing an efficient and reliable beverage machine lid pressing device is of significant practical importance. Utility Model Content
[0004] To improve the accuracy and applicability of capping and increase efficiency, this application provides a capping device for a beverage machine.
[0005] The beverage machine capping device provided in this application adopts the following technical solution:
[0006] A beverage machine capping device includes a bracket, on which a capping guide plate and a cup lid annular pressure plate are connected. The capping guide plate is located above the cup lid annular pressure plate. A plurality of capping guide posts are arranged between the capping guide plate and the cup lid annular pressure plate. A buffer spring is sleeved on each capping guide post. The two ends of the buffer spring abut against the capping guide plate and the cup lid annular pressure plate. The cup lid annular pressure plate abuts against the cup lid. A driving component for driving the capping guide plate to move is provided on the bracket.
[0007] By adopting the above technical solution, when the cup lid is pressed, the pressing guide plate moves downward under the downward drive of the driving component. The pressing guide plate transmits force to the cup lid ring pressing plate through the pressing guide post. At the same time, the pressing guide post spring plays a buffering role, so that the pressing force is moderate. It is neither too large, which will cause the cup lid or cup to deform, nor too small, which will cause the lid to not seal properly. The pressing guide post and the buffer spring can dynamically adjust the force during the pressing process to avoid excessive or insufficient pressure, and ensure that cup lids of different materials and shapes are effectively pressed.
[0008] Preferably, the driving component is an electric actuator, which is fixedly mounted on the bracket, and the bottom end of the electric actuator is fixedly connected to the pressure cover guide plate.
[0009] By adopting the above technical solution, the staff can move the pressure plate guide plate by using an electric push rod.
[0010] Preferably, a pressure sensor is installed on the annular pressure plate of the cup lid, and a control component for controlling the electric push rod is provided on the bracket.
[0011] By adopting the above technical solution, when the cup lid is pressed against the annular pressure plate, the pressure sensor can transmit the pressure on the cup lid to the control component. The control component can control the movement of the electric push rod according to the pressure, thereby adjusting the thrust of the pressure plate according to the different forces on different materials.
[0012] Preferably, the inner wall of the cup lid annular pressure plate is provided with multiple guide grooves, a pressure rod slides in the guide grooves, the pressure plate abuts against the cup lid, and a driving assembly for driving the pressure rod is provided inside the cup lid annular pressure plate.
[0013] By adopting the above technical solution, the operator can drive the pressure rod along the guide groove to move a certain distance towards the center of the cup lid ring pressure plate according to the size of the cup lid to be pressed, so that the cup lid ring pressure plate can be used for cup lids of different sizes, thus improving its applicability.
[0014] Preferably, the drive assembly includes a first gear, multiple lead screws, and multiple second gears. The lead screws are rotatably disposed within the guide groove. The pressure rod is threadedly connected to the lead screw. The second gears are fixedly sleeved on the lead screw. The annular pressure plate of the cup lid has a rotating groove on its peripheral sidewall. The first gear is rotatably disposed within the rotating groove. The rotating groove is connected to multiple guide grooves. The second gears mesh with the first gear.
[0015] By adopting the above technical solution, when the cup lid to be compacted is small, and the diameter of the cup lid annular pressure plate is larger than the cup lid, the worker rotates the first gear. The rotation of the first gear drives multiple second gears to rotate, and the rotation of the second gears drives the lead screw to rotate. The rotation of the lead screw drives the pressure rod to move towards the center of the cup lid annular pressure plate, so that the pressure rod abuts against the cup lid and compacts the cup lid.
[0016] Preferably, the cup lid annular pressure plate has multiple connecting holes on the side wall away from the pressure plate guide post, and a clamping rod can be threaded onto the connecting holes, the clamping rod abutting against the cup lid.
[0017] By adopting the above technical solution, when the cup lid to be compacted is irregular in shape, the worker can screw the clamping rod into the corresponding connecting hole according to the shape of the cup lid. Thus, when the cup lid ring pressure plate is driven, the clamping rod on it abuts against a ring of the cup lid surface to complete the cup lid compaction.
[0018] Preferably, the clamping rod includes a main rod and a telescopic rod, the main rod has a telescopic groove, and the telescopic rod is screwed to the telescopic groove.
[0019] By adopting the above technical solution, some cup lids are designed with different shapes and patterns at different heights. In this case, the staff can adjust the length of the clamping rod accordingly.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. During the pressing operation of the cup lid, the pressing guide plate moves downward under the downward drive of the driving component. The pressing guide plate transmits force to the cup lid ring pressing plate through the pressing guide post. At the same time, the pressing guide post spring plays a buffering role, so that the pressing force is moderate. It is neither too large, which will cause the cup lid or cup to deform, nor too small, which will cause the lid to not seal properly. The pressing guide post and the buffer spring can dynamically adjust the force during the pressing process to avoid excessive or insufficient pressure, and ensure that cup lids of different materials and shapes are effectively pressed.
[0022] 2. When the cup lid is pressed against the annular pressure plate, the pressure sensor can transmit the pressure on the cup lid to the control component. The control component can control the movement of the electric push rod according to the pressure, so as to adjust the pushing force of the pressure plate according to the different forces on different materials.
[0023] 3. The operator can drive the pressure rod along the guide groove towards the center of the cup lid ring pressure plate according to the size of the cup lid to be pressed, so that the cup lid ring pressure plate can be used for cup lids of different sizes, thus improving its applicability.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] Implementation 1
[0031] Embodiment 1 of this application discloses a beverage machine capping device, such as... Figure 1 As shown, the device includes a bracket 1, on which a drive component electric actuator 6 is mounted. A capping guide plate 2 is fixedly welded to the piston rod of the electric actuator 6. The capping guide plate 2 is cylindrical, and multiple capping guide posts 4 slide through its end face. The capping guide posts 4 are also cylindrical. A cup lid annular pressure plate 3 is located below the capping guide plate 2. The cup lid annular pressure plate 3 is ring-shaped, and the bottom ends of the multiple capping guide posts 4 are fixedly welded to the upper end face of the cup lid annular pressure plate 3. The lower end face of the cup lid annular pressure plate 3 abuts against the cup lid. The top end of the capping guide post 4 passes through the capping guide plate 2 and is threaded with a fixing nut, thereby connecting the capping guide plate 2 and the cup lid annular pressure plate 3 together. A buffer spring 5 is sleeved on the capping guide post 4. The buffer spring 5 is arranged vertically, and its top and bottom ends abut against the lower end face of the capping guide plate 2 and the upper end face of the cup lid annular pressure plate 3. A pressure sensor 7 is installed on the annular pressure plate 3 of the cup lid to detect the pressure on the annular pressure plate 3 of the cup lid. A control component 8 is provided on the bracket 1 to receive the signal from the pressure sensor 7. The control component 8 can adjust the operation of the electric push rod 6 according to the received pressure.
[0032] The implementation principle of Embodiment 1 of this application is as follows: When the cup lid is pressed, the operator pushes the lid guide plate 2 downward through the electric push rod 6. The movement of the lid guide plate 2 causes the cup lid annular pressure plate 3 to move together towards the cup lid. When the cup lid annular pressure plate 3 abuts against and presses the cup lid, the pressure sensor 7 can transmit the pressure on the cup lid to the control component 8. The control component 8 can control the movement of the electric push rod 6 according to the pressure, thereby adjusting the pushing force of the lid guide plate 2 according to the different forces on different materials. At the same time, the lid guide plate 2 transmits force to the cup lid annular pressure plate 3 through the lid guide post 4. The buffer spring 5 on the lid guide post 4 plays a buffering role, so that the pressing force is moderate. It is neither too large, which will cause the cup lid or cup to deform, nor too small, which will cause the lid to not be sealed tightly. The lid guide post 4 and the buffer spring 5 can dynamically adjust the force during the pressing process to avoid excessive or insufficient pressure, and ensure that cup lids of different materials and shapes are effectively pressed.
[0033] Example 2
[0034] like Figure 2 As shown, the difference between this embodiment 2 and embodiment 1 is that: multiple guide grooves 9 are provided on the inner circumferential wall of the cup lid annular pressure plate 3, and the multiple guide grooves 9 are evenly distributed on the inner circumferential wall of the cup lid annular pressure plate 3. A pressure rod 10 slides in the guide groove 9, and the lower end face of the pressure rod 10 abuts against the cup lid. A driving assembly 11 for driving the pressure rod 10 is provided in the cup lid annular pressure plate 3. The drive assembly 11 includes a first gear 12, multiple lead screws 13, and multiple second gears 14. The lead screws 13 are rotatably disposed in the guide groove 9, with one end rotatably disposed on the inner wall of the guide groove 9 and the other end threadedly connected to the pressure rod 10. The second gears 14 are fixedly sleeved on the end of the lead screw 13 away from the pressure rod 10. A rotating groove 15 is opened on the outer peripheral side wall of the cup lid annular pressure plate 3. The rotating groove 15 is circular. The first gear 12 is rotatably disposed in the rotating groove 15 and rotates on the cup lid annular pressure plate 3. The rotating groove 15 is connected to the multiple guide grooves 9, and the second gears 14 mesh with the first gear 12.
[0035] The implementation principle of Embodiment 2 of this application is as follows: When the diameter of the cup lid to be pressed is small, and the cup lid annular pressure plate 3 cannot contact the lid for pressurization, the operator can adjust the position of the pressure rod 10 according to the size of the cup lid. At this time, the operator rotates the first gear 12, which drives multiple second gears 14 to rotate. The rotation of the second gears 14 drives the lead screw 13 to rotate, which in turn drives the pressure rod 10 to move towards the center of the cup lid annular pressure plate 3. This reduces the center diameter of the cup lid annular pressure plate 3, and the lower end face of the pressure rod 10 abuts against the cup lid, pressing it firmly. Therefore, the cup lid annular pressure plate 3 can be used for cup lids of different sizes, improving its applicability.
[0036] Example 3
[0037] like Figure 3 As shown, the difference between this embodiment 3 and embodiment 2 is that: the lower end face of the cup lid annular pressure plate 3 has multiple connecting holes 16 that are vertically upward. A clamping rod 17 can be threaded into the connecting holes 16. The clamping rod 17 includes a main rod 18 and a telescopic rod 19. Both the main rod 18 and the telescopic rod 19 are cylindrical and are arranged in the vertical direction. A telescopic groove 20 is provided on the main rod 18. The telescopic rod 19 is screwed into the telescopic groove 20. The bottom end of the clamping rod 17 abuts against the cup lid.
[0038] The implementation principle of Embodiment 3 of this application is as follows: Merchants may design cup lids with corresponding themes according to festivals and other scenarios. At this time, the cup lids may be irregularly shaped. When the shape of the cup lid to be compacted is irregular, the staff can screw the clamping rod 17 into the corresponding connecting hole 16 according to the shape of the cup lid, so that multiple clamping rods 17 can compact the cup lid. In addition, when the cup lid is designed with different shapes and patterns, the staff can adjust the length of the clamping rod 17 accordingly.
[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
