Description

Technical Field

[0001] This application relates to the field of cup sealing machines, and more particularly to a membrane suction and placement device for a cup sealing machine. Background Technology

[0002] A cup sealing machine, also known as a cup rim sealing machine, is a device that uses heat and pressure to seal a layer of plastic or paper film onto the rim of a cup. It is widely used in food and beverage establishments such as milk tea shops, cafes, juice bars, and fast food restaurants, primarily for takeaway drinks.

[0003] In related technologies, a cup sealing machine includes a membrane picking and placing device, which comprises a lifting drive source, a rotation drive source, and a membrane picking and placing assembly. The lifting drive source drives the membrane picking and placing assembly to move up and down, the rotation drive source drives the membrane picking and placing assembly to rotate, and the membrane picking and placing assembly picks up or places the membrane. In actual operation, the lifting drive source first drives the membrane picking and placing assembly to rise, then the rotation drive source drives the membrane picking and placing assembly to rotate, the membrane picking and placing assembly picks up the membrane, then the rotation drive source drives the membrane picking and placing assembly to rotate back to its original position, and the lifting drive source drives the membrane picking and placing assembly to descend to directly above the cup opening, where the membrane picking and placing assembly releases the membrane and places it on the cup opening. However, the above-mentioned membrane picking and placing device requires at least two drive sources, resulting in high energy consumption and a large space occupation. Utility Model Content

[0004] To reduce operating costs, this application provides a membrane suction and placement device for a cup sealing machine.

[0005] This application provides a membrane suction and placement device for a cup sealing machine, which adopts the following technical solution: A film pick-up and placement device for a cup sealing machine includes a frame and a rotation drive assembly. The frame is provided with a lifting drive source, and a mounting seat is slidably disposed on the frame in a vertical direction. The lifting drive source is used to drive the mounting seat to lift and lower. A film pick-up and placement assembly is rotatably disposed on the mounting seat. The film pick-up and placement assembly includes a rotating shaft. The rotation drive assembly includes a rotating wheel fixedly disposed on the rotating shaft. The circumferential sidewall of the rotating wheel has meshing teeth. The rotation drive assembly also includes a meshing member disposed on the frame, and the meshing member is meshed with the rotating wheel.

[0006] By adopting the above technical solution, the rotation drive assembly is designed to include a rotating wheel fixed on the rotating shaft and a fixed meshing component that meshes with the rotating wheel. When the mounting base moves vertically under the drive of the lifting drive source, it can automatically drive the rotating shaft and the diaphragm picking and placing assembly to rotate through the meshing relationship. This allows the diaphragm picking and placing assembly to synchronously complete angle adjustment during the lifting and lowering process. There is no need to set up an additional independent rotation drive source, which effectively simplifies the structure, reduces manufacturing costs and energy consumption, ensures reliable operation of the device, has a long service life, and improves the space utilization efficiency of the equipment.

[0007] Optionally, the meshing element is a rack, which is fixedly mounted on the frame, and the meshing teeth on the rack are arranged in a vertical direction. The rotating wheel is a gear.

[0008] By adopting the above technical solution, the meshing component is specifically set as a rack fixed on the frame, and the rotating wheel is designed as a gear, so that the rotating wheel can achieve reliable transmission through the meshing of the rack and gear when it moves up and down along the rack. It has high rigidity, large load-bearing capacity, simple structure, precise transmission, is easy to process, manufacture and install, and is easy to maintain, further enhancing the stability and motion controllability of the device.

[0009] Optionally, the rack includes a clearance portion and a transmission portion. The clearance portion is located below and connected to the transmission portion. The surface of the clearance portion near the rotating wheel is flat. The surface of the transmission portion near the rotating wheel has meshing teeth. Both the clearance portion and the transmission portion are located within the movement range of the rotating wheel in the vertical direction.

[0010] By adopting the above technical solution, the rack is divided into a clearance section and a transmission section. The transmission section is equipped with meshing teeth, and the clearance section is equipped with a plane. This allows the rotating wheel to slide along the plane without rotating during the non-transmission stage, and to mesh and transmit power only during the transmission section. This enables the diaphragm pick-and-place assembly to perform rotational action only at a specific position. That is, the diaphragm pick-and-place assembly is first lifted a certain distance before rotating, which improves the accuracy and applicability of motion control and avoids unnecessary rotational interference.

[0011] Optionally, the frame is provided with a strip-shaped hole extending in the vertical direction, and the rotating shaft slides within the strip-shaped hole.

[0012] By adopting the above technical solution, vertically extending strip holes are set on the frame, allowing the rotating shaft to slide within them, thus ensuring the guiding function of the rotating shaft during the lifting process. The structure is compact and easy to install.

[0013] Optionally, a rolling bearing is fitted onto the rotating shaft, and the rolling bearing is slidably disposed within the strip-shaped hole.

[0014] By adopting the above technical solution, rolling bearings are installed on the rotating shaft, allowing it to slide within the slotted hole. This effectively reduces the friction between the rotating shaft and the slotted hole, improves the smoothness of movement and service life, and reduces operating noise.

[0015] Optionally, the frame is provided with guide rails, and the mounting base is provided with a guide groove extending vertically for the guide rails to be inserted and slid.

[0016] By adopting the above technical solution, a guide rail is set on the frame and a guide groove is opened on the mounting base, so that the mounting base can move smoothly along the guide rail during the lifting process, which enhances the motion rigidity and positioning accuracy of the entire diaphragm picking and placing assembly and prevents swaying or jamming.

[0017] Optionally, the frame includes multiple support plates, each support plate enclosing a receiving cavity, and the rotation drive assembly is disposed in the receiving cavity.

[0018] By adopting the above technical solution, the frame is designed as a cavity structure formed by multiple support plates, and the rotation drive component is placed inside it. This helps to protect the transmission components from external pollution or interference, while making the overall structure more compact, beautiful, and easy to maintain and encapsulate.

[0019] Optionally, the membrane picking and placing assembly further includes a suction cup disposed on the rotating shaft, the suction cup being used to pick up the membrane.

[0020] By adopting the above technical solution, a suction cup is set on the rotating shaft, which can reliably adsorb the membrane and realize the automatic picking and placing of the membrane. Compared with holding the membrane by grippers, the structure is simple and easy to operate, and it is suitable for a variety of membrane materials, thus improving the versatility and working efficiency of the device.

[0021] Optionally, the suction cup includes a mounting rod, the circumferential sidewall of which has an external thread, and the rotating shaft has a threaded groove, the suction cup being threadedly connected to the rotating shaft.

[0022] By adopting the above technical solution, the suction cup and the rotating shaft are designed with a threaded connection, making the installation and replacement of the suction cup more convenient and quick, and facilitating adjustments according to different diaphragm sizes or types, thereby enhancing the adaptability and maintenance convenience of the equipment.

[0023] Optionally, a fixed wheel is rotatably mounted on the frame. Both the fixed wheel and the rotating wheel are sprockets, and the meshing element is a chain. The two ends of the chain are respectively wound around the fixed wheel and the rotating wheel.

[0024] By adopting the above technical solution, both the rotating wheel and the fixed wheel are set as sprockets, and the meshing part is designed as a chain, so that the rotating shaft can rotate through the chain drive during the lifting process. The transmission is smooth and the noise is low, which is suitable for the transmission needs of long distances or complex layouts, thus expanding the application range of the device.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The diaphragm loading and unloading assembly can simultaneously adjust its angle during the lifting and lowering process without the need for an additional independent rotation drive source. This effectively simplifies the structure, reduces manufacturing costs and energy consumption, ensures reliable operation, extends service life, and improves the space utilization efficiency of the equipment. 2. This allows the rotating wheel to achieve reliable transmission through gear and rack meshing when it moves up and down along the rack. It has high rigidity, large load-bearing capacity, simple structure, precise transmission, is easy to process, manufacture and install, and is easy to maintain, further enhancing the stability and motion controllability of the device.

[0030] The following combination Figures 1-3 This application will be described in further detail.

[0031] Example 1: This embodiment discloses a membrane suction and placement device for a cup sealing machine. (Refer to...) Figure 1 and Figure 2The film pick-up and placement device of the cup sealing machine includes a frame 1, a rotation drive assembly 2, a lifting drive source 3, a mounting base 4, and a film pick-up and placement assembly 5. The lifting drive source 3 is fixedly mounted on the frame 1, and the mounting base 4 is slidably mounted on the frame 1 in a vertical direction. The lifting drive source 3 drives the mounting base 4 to rise and fall. The film pick-up and placement assembly 5 is rotatably mounted on the mounting base 4 and includes a rotating shaft 51. The rotation drive assembly 2 includes a rotating wheel 21 fixedly mounted on the rotating shaft 51 and a meshing member 22 mounted on the frame 1. Meshing teeth are formed on the circumferential sidewall of the rotating wheel 21. The meshing member 22 engages with the rotating wheel 21, so that when the mounting base 4 rises and falls, the meshing relationship drives the rotating shaft 51 and the film pick-up and placement assembly 5 to rotate, eliminating the need for an additional rotation drive source, simplifying the structure, and reducing cost and energy consumption.

[0032] Reference Figure 2 The frame 1 includes multiple support plates 12, which together form a closed housing with a cavity 13 in which the rotary drive assembly 2 is located. The support plates 12 are typically made of metal, such as stainless steel, which offers good strength and corrosion resistance. The multiple support plates 12 are joined together by welding or bolting to form a relatively closed cavity 13. This protects the rotary drive assembly 2 from external dust and debris, while also making the overall structure more compact and aesthetically pleasing, and facilitating future maintenance and encapsulation. The shape of the cavity 13 can be designed according to the specific structure and dimensions of the rotary drive assembly 2, and is typically rectangular.

[0033] Reference Figure 2 The lifting drive source 3 can be a cylinder or an electric actuator, etc. Taking a cylinder as an example, the cylinder body is fixed on the frame 1, and the piston rod of the cylinder is bolted to the mounting base 4. When the piston rod of the cylinder extends or retracts, it can drive the mounting base 4 to move vertically up and down on the frame 1.

[0034] Reference Figure 1 and Figure 2 The axial direction of the rotating shaft 51 is defined as the front-to-back direction, and the vertical direction as the up-and-down direction. Both support plates 12, arranged along the front-to-back direction, have vertically extending slots 11 that penetrate the front and back surfaces of the support plates 12 along the rotating shaft 51. The rotating shaft 51 is inserted into and passes through the support plates 12 and the receiving cavity 13, and slides up and down within the slots 11. The slots 11 guide the sliding of the rotating shaft 51, preventing it from shifting.

[0035] Reference Figure 1A rolling bearing 6 is fitted onto the rotating shaft 51, and the rolling bearing 6 is slidably installed within one of the slotted holes 11. The rolling bearing 6 reduces the friction between the rotating shaft 51 and the slotted hole 11, improves the smoothness of movement and the service life of the rotating shaft 51, and reduces the noise generated during operation. The rolling bearing 6 is generally a deep groove ball bearing, which has the advantages of simple structure and convenient use.

[0036] Reference Figure 2 The mounting base 4 has guide grooves 41 extending vertically on both its left and right surfaces, and these guide grooves 41 penetrate the upper and lower surfaces of the mounting base 4. A guide rail 7 is bolted to the frame 1, inserted into the guide groove 41, and the mounting base 4 can slide along the guide rail 7. The guide rail 7 is generally a linear guide rail, which has high precision and smooth movement. The cooperation between the guide groove 41 and the guide rail allows the mounting base 4 to move smoothly along a fixed path during lifting and lowering, enhancing the motion rigidity and positioning accuracy of the entire diaphragm handling assembly 5, and preventing the mounting base 4 from swaying or jamming during movement.

[0037] Reference Figure 1 and Figure 2 A rotating wheel 21, which is a gear, is mounted on a rotating shaft 51. The meshing component 22 is a rack, which is bolted to one of the support plates 12, with the meshing teeth arranged vertically. When the mounting base 4 moves vertically under the drive of the lifting drive source 3, the rotating wheel 21 moves along the rack. Due to the meshing relationship between the gear and the rack, the rotating wheel 21 rotates, thereby driving the rotating shaft 51 and the diaphragm handling assembly 5 to rotate. The gear and rack design enables reliable transmission when the rotating wheel 21 moves up and down along the rack, featuring high rigidity, high load-bearing capacity, simple structure, precise transmission, ease of manufacturing and installation, and convenient maintenance.

[0038] Reference Figure 2 The rack includes a clearance portion 221 and a transmission portion 222. The clearance portion 221 is located below the transmission portion 222 and is connected to the transmission portion 222. The surface of the clearance portion 221 near the rotating wheel 21 is flat. The surface of the transmission portion 222 near the rotating wheel 21 has meshing teeth. Both the clearance portion 221 and the transmission portion 222 are within the range of movement of the rotating wheel 21 in the vertical direction.

[0039] When the diaphragm pick-and-place assembly 5 is in its initial position, the lifting drive source 3 drives the mounting base 4 to rise, lifting the diaphragm pick-and-place assembly 5 along with it. The gear first passes through the clearance part 221, and then through the transmission part 222. This design ensures that the rotating wheel 21 does not rotate during the non-transmission phase, that is, when the clearance part 221 moves, because the surface of the clearance part 221 is flat. The rotating wheel 21 only drives the diaphragm pick-and-place assembly 5 to rotate when the transmission part 222 engages in transmission. This allows the diaphragm pick-and-place assembly 5 to perform a rotational action only at a specific position, that is, the diaphragm pick-and-place assembly 5 is lifted a certain distance before rotating, improving the accuracy and applicability of motion control and avoiding unnecessary rotational interference.

[0040] Reference Figure 1 The membrane picking and placing assembly 5 also includes multiple suction cups 52. In this embodiment, two suction cups 52 are provided and arranged along the axial direction of the rotating shaft 51. The suction cups 52 are detachably connected to the rotating shaft 51 and are used to adsorb membranes. The suction cups 52 can be made of rubber, which has good adsorption performance and can reliably adsorb membranes, realizing automatic membrane picking and placing. Compared with holding membranes by grippers, the suction cups 52 have a simple structure, are easy to operate, and are suitable for various membrane materials, improving the versatility and working efficiency of the device.

[0041] Reference Figure 3 The suction cup 52 includes a mounting rod 521, with external threads formed on its circumferential sidewall. A threaded groove is provided on the rotating shaft 51, and the suction cup 52 is mounted on the rotating shaft 51 via a threaded connection. This threaded connection method makes the installation and replacement of the suction cup 52 very convenient and quick. When it is necessary to replace the suction cup 52 according to different diaphragm sizes or types, simply unscrew the suction cup 52 from the rotating shaft 51 and then install the new suction cup 52. In other embodiments, the suction cup 52 can be fixed to the rotating shaft 51 by a snap-fit ​​connection.

[0042] The working principle of the film pick-up and placement device of the sealing machine in Embodiment 1 of this application is as follows: The lifting drive source 3 drives the mounting base 4 to rise, which in turn lifts the film pick-up and placement component 5. The film pick-up and placement component 5 is lifted until the gear meshes with the meshing teeth on the transmission part 222. While the film pick-up and placement component 5 continues to rise, it rotates, which causes the rotating shaft 51 to rotate the suction cup 52 to a suitable angle. The suction cup 52 picks up the film. The lifting drive source 3 drives the mounting base 4 to fall, which in turn lowers the film pick-up and placement component 5. The suction cup 52 rotates until the film is directly above the cup. The suction cup 52 releases the film and places the film on the cup opening, where other devices perform the sealing process.

[0043] Example 2: The difference between this embodiment and Embodiment 1 is that: a fixed wheel is rotatably mounted on the frame 1, and both the fixed wheel and the rotating wheel 21 are sprockets. The meshing component 22 is a chain, with both ends of the chain wound around the fixed wheel and the rotating wheel 21, respectively. A floating idler wheel, also a sprocket, is rotatably mounted on the mounting base 4. A swing rod is also mounted on the mounting base 4, and the swing rod can rotate around a fulcrum, which is mounted on the mounting base 4. The floating idler wheel is mounted on one end of the swing rod, and the chain is also wound around the floating idler wheel. A tension spring is also connected between the swing rod and the mounting base 4 to provide a force to the floating idler wheel that presses against the chain, thereby achieving automatic chain tensioning.

[0044] When the mounting base 4 is raised and lowered by the lifting drive source 3, the rotating wheel 21 moves up and down together with the rotating shaft 51. Since the chain is wound around the fixed wheel, the rotating wheel 21, and the floating idler wheel, the rotating wheel 21 rotates during movement via chain drive, thereby driving the rotating shaft 51 and the diaphragm pick-and-place assembly 5 to rotate. Under the action of the tension spring, the floating idler wheel changes its position by oscillating, thus automatically adjusting the chain loop length, perfectly absorbing this change, always maintaining chain tension, and not restricting the pure vertical movement of the fixed base. Chain drive features smooth transmission and low noise, making it suitable for transmission needs of longer distances or complex layouts, expanding the application range of the device. For example, in some cup sealing machines with complex spatial layouts, chain drive can better adapt to different installation environments.

[0045] 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.
