Description

Technical Field

[0001] This invention relates to the field of tea packaging technology for hidden tea cups, and more specifically, to a rotary multi-station automatic hidden tea cup production equipment. Background Technology

[0002] Hidden tea cup processing equipment is a type of specialized machinery used to produce hidden tea cups. As an innovative tea drinking container, the hidden tea cup combines tea leaves with disposable paper cups. The processing technology uses high-temperature hot pressing and other methods to seal a certain amount of tea leaves inside the filter paper layer at the bottom of the cup, thereby achieving a hidden packaging of the tea leaves. This design effectively maintains the freshness and aroma of the tea leaves, bringing consumers a more convenient and high-quality tea drinking experience.

[0003] In the field of hidden tea cup processing equipment, such as the fully automatic disc-type hidden tea cup filling and sealing equipment disclosed in Chinese Patent Application No. 202422848040.3, the working process of this equipment is as follows: First, an empty tea cup is accurately placed on a turntable using a cup-dropping device. Then, the equipment uses a specific filling device to put a certain amount of tea leaves into the empty tea cup. After the tea leaves are put into the tea cup, a film-cutting device cuts the heat-sealing film into a size and shape suitable for sealing the tea cup. After the film is cut, a film detection photoelectric eye will detect the cut film. The qualified film will be moved to the heat-sealing device. At the same time, the turntable continues to rotate, transferring the tea cup with tea leaves to the position of the heat-sealing device. Finally, the heat-sealing device heat-seales the heat-sealing film into the tea cup through high-temperature hot pressing, completing the sealing process of the hidden tea cup.

[0004] The equipment described in the aforementioned public documents has some limitations in practical applications. Since each process in the equipment is carried out separately and independently, there is a lack of close coordination and continuity between the processes, which leads to inefficiency in the entire production process. For example, between processes such as cup placement, tea feeding, film cutting, inspection, film transfer, and heat sealing, a certain amount of time is required for the transfer of teacups and films and the adjustment of the equipment. This extra time consumption greatly reduces production efficiency. Summary of the Invention

[0005] To address the problems existing in the above-mentioned technologies, the purpose of this invention is to provide a rotary multi-station automatic hidden tea cup production equipment, which can realize the dual processes of single cylinder pressing and film cutting and heat sealing. Combined with the coaxial positioning of the paper cup by the cup holder, it simplifies the processing flow and greatly improves production efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A rotary multi-station automatic teacup production device includes a drive motor, a turntable fixedly connected to the upper end of the drive motor, multiple sets of teacup holes being formed through the turntable, a cutting cylinder being arranged above one set of teacup holes, a cylinder being arranged above the cutting cylinder, a pressure plate being fixedly connected to the lower end of the cylinder, a moving column being fixedly connected to the lower end of the pressure plate, a first spring being sleeved on the outside of the moving column, the upper end of the first spring being fixedly connected to the pressure plate, the lower end of the first spring being fixedly connected to the cutting cylinder, the lower end of the moving column movably penetrating through the upper wall of the cutting cylinder and being fixedly connected to a heat sealing head, and film feeding and receiving assemblies arranged on both sides of the turntable, the film feeding and receiving assemblies being used to control the feeding and receiving of heat sealing film below the cutting cylinder according to the extension and retraction movement of the cylinder.

[0008] Furthermore, the film feeding and receiving assembly includes a film feeding roller located on one side of the film cutting cylinder. A heat-sealing film is wound on the film feeding roller. A first synchronous pulley is fixedly connected to one end of the film feeding roller. A synchronous belt is wound around the first synchronous pulley. A second synchronous pulley is also wound around the inner wall of the synchronous belt. A one-way component is provided at the second synchronous pulley. The one-way component is used to control the second synchronous pulley to rotate in one direction according to the extension and retraction of the cylinder.

[0009] Furthermore, the film take-up and undo assembly also includes a take-up roller, with the end of the heat-sealing film on the undo roller away from the undo roller wound around the take-up roller, and a third synchronous pulley fixedly connected to one end of the take-up roller, the outer circumference of the third synchronous pulley being wound around the inner wall of the synchronous belt.

[0010] Furthermore, the unidirectional component includes a control plate, one side of which has multiple sets of evenly distributed grooves from top to bottom. Each set of grooves is rotatably connected to a ratchet. A second spring is fixedly connected between the upper end of the ratchet and the upper inner wall of the groove. A ratchet wheel is engaged with one side of the ratchet. The ratchet wheel is fixedly connected to a second synchronous pulley. A fixing rod is fixedly connected between the control plate and the pressure plate.

[0011] Furthermore, the membrane take-up and release assembly also includes a sleeve made of magnetic material. A connecting rod is rotatably arranged inside the sleeve. The end of the connecting rod away from the sleeve is fixedly connected to the second synchronous pulley. Multiple sets of permanent magnets are embedded and installed on the outer circular surface of the connecting rod inside the sleeve.

[0012] Furthermore, the attraction force of the multiple sets of permanent magnets on the sleeve is greater than the elastic force of a single second spring.

[0013] Furthermore, an arc-shaped groove is provided on the side wall of the movable column, and a slider is slidably disposed in the arc-shaped groove. The end of the slider away from the arc-shaped groove is fixedly connected to the film cutting cylinder.

[0014] Furthermore, a bracket is fixedly connected to the end of the sleeve away from the connecting rod, and both the drive motor and the cylinder are mounted on the bracket.

[0015] Furthermore, both ends of the film feeding roller and the film taking roller are rotatably connected to a support frame, and the lower end of the support frame is fixedly connected to a base; A cup holder is fixedly connected to the lower end face of the turntable at the teacup hole.

[0016] Furthermore, an automatic quantitative feeder is provided on the right side of the turntable. The automatic quantitative feeder is used to dispense a fixed amount of tea leaves into the cup. The outlet of the automatic quantitative feeder is connected to a discharge pipe. The end of the discharge pipe away from the automatic quantitative feeder is located directly above one of the teacup holes.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This solution uses four workstations evenly set around the turntable and drives the motor to rotate 90° precisely to achieve continuous and automated production of feeding, quantitative tea dispensing, heat sealing and film cutting, and material picking, without the need for frequent manual switching of processes. At the same time, the cylinder presses down once to link the film cutting and heat sealing processes, combined with the cup holder's coaxial positioning of the paper cup, which simplifies the processing flow, greatly improves production efficiency, avoids misalignment of process connections, ensures the accuracy of tea dispensing and heat sealing of the hidden tea cup, and is suitable for large-scale mass production needs.

[0018] (2) This design features a rigid linkage structure between the film take-up and release assembly and the cylinder. Through a one-way ratchet mechanism combined with the magnetic adsorption of a permanent magnet, precise control of the static cutting and synchronous take-up and release of the heat-sealing film is achieved. When the cylinder extends, the magnetic attraction constrains the ratchet to stay still, ensuring the stability of the film cutting. When shrinking, the driving force overcomes the magnetic attraction and links the take-up and release film rollers to move synchronously. New film can be put in and waste film can be recycled without an additional driving source. This design simplifies the equipment structure, reduces energy consumption, ensures the tension and conveying accuracy of the heat-sealing film, and reduces film waste.

[0019] (3) This solution uses the cooperation between the arc groove of the moving column and the slider of the cutting cylinder to convert the axial pressure of the cylinder into the circumferential rotational force of the cutting cylinder, forming a composite cutting mode of axial pressure and circumferential rolling. Compared with traditional rigid cutting, this structure effectively reduces the stretching deformation and burr tearing of the heat-sealing film, reduces the pressure required for cutting, and improves the flatness of the cut.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 9A rotary multi-station automatic teacup production equipment includes a drive motor 1, a turntable 2 fixedly connected to the upper end of the drive motor 1, a plurality of teacup holes 3 through which the turntable 2 is formed, a cutting cylinder 9 is arranged above one of the teacup holes 3, a cylinder 5 is arranged above the cutting cylinder 9, a pressure plate 6 is fixedly connected to the lower end of the cylinder 5, a moving column 7 is fixedly connected to the lower end of the pressure plate 6, a first spring 10 is sleeved on the outside of the moving column 7, the upper end of the first spring 10 is fixedly connected to the pressure plate 6, the lower end of the first spring 10 is fixedly connected to the cutting cylinder 9, the lower end of the moving column 7 movably penetrates the upper wall of the cutting cylinder 9 and is fixedly connected to a heat sealing head 8, and film feeding and receiving assemblies are arranged on both sides of the turntable 2, the film feeding and receiving assemblies are used to control the heat sealing film 28 to be fed and received below the cutting cylinder 9 according to the extension and retraction of the cylinder 5; An automatic quantitative feeder 29 is provided on the right side of the turntable 2. The automatic quantitative feeder 29 is used to feed a certain amount of tea into the cup. The outlet of the automatic quantitative feeder 29 is connected to a discharge pipe 31. One end of the discharge pipe 31 away from the automatic quantitative feeder 29 is located directly above one of the teacup holes 3. A cup holder 30 is fixedly connected to the lower end face of the turntable 2 at the teacup hole 3.

[0025] In this embodiment, multiple sets of teacup holes 3 on the turntable 2 are evenly distributed circumferentially, and the position of each set of teacup holes 3 corresponds one-to-one with the four workstations of feeding, quantitative tea leaf dispensing, heat sealing and film cutting, and material unloading. This ensures that the workstations can be accurately switched after the turntable 2 rotates 90° each time, realizing continuous production. The specific workflow is as follows: Loading station: Empty paper cups are orderly placed into the teacup hole 3 at the front end of the turntable 2 by an automatic robotic arm or automatic unloading device. The cup holder 30 fixed at the lower end of the teacup hole 3 fits against the outer wall of the paper cup to support the paper cup. Tea dispensing station: After the empty paper cup is in place, the drive motor 1 drives the turntable 2 to rotate 90°, so that the paper cup is accurately moved to the bottom of the discharge pipe 31. The automatic quantitative feeder 29 starts and accurately injects the preset weight of tea into the paper cup through the discharge pipe 31. After the dispensing is completed, the turntable 2 is ready to switch to the next station. It should be noted that the automatic quantitative feeder 29 is an existing publicly available device and is suitable for quantitative dispensing of granular and powdery materials. Heat-sealing and film-cutting station: Turntable 2 rotates 90° again, and the paper cup containing tea leaves moves directly below the film-cutting cylinder 9. At this time, the heat-sealing film 28, supported by the film-retracting assembly, maintains a distance of 2-5 mm from the surface of turntable 2. This distance avoids friction between the heat-sealing film 28 and turntable 2, which affects rotation, and ensures that the lower end of the film-cutting cylinder 9 is in full contact with the heat-sealing film 28. This process achieves integrated film cutting and heat sealing through a single downward press of cylinder 5, simplifying the process flow and improving production efficiency. The heat-sealing head 8 heats according to the preset heating parameters, and then cylinder 5 extends, driving the pressure plate 6, moving column 7, and film-cutting cylinder 9 to move downwards synchronously. The lower end of the film-cutting cylinder 9 is blade-shaped, first contacting the heat-sealing film 28 and covering the edge of the tea cup hole 3. The cylinder 5 continues to extend, and the pressure plate 6 squeezes the first spring 10. The first spring 10 contracts and stores energy. Under the pressure of the first spring 10, the cutting cylinder 9 cuts the heat-sealing film 28 to form a circular film that matches the diameter of the paper cup. As the pressure plate 6 continues to move downward, the moving column 7 drives the heat-sealing head 8 with its own heating function to pass through the cutting cylinder 9 and press the cut circular heat-sealing film 28 into the inside of the paper cup. After the heat-sealing head 8 is attached to the inner wall of the paper cup, the film is heat-sealed at a preset height on the inner wall of the paper cup through the heating action, thus completing the seal. When the cylinder 5 retracts, the film retraction and release assembly moves synchronously, releasing a new heat-sealing film 28 of the corresponding length to below the cutting cylinder 9, while recovering the cut waste film for the next processing. Material picking station: After heat sealing, drive motor 1 drives turntable 2 to rotate 90° for the third time, and the finished tea cup moves to the material picking station. The paper cup is taken out from the tea cup hole 3 by an automatic robot, automatic picking device or manual method, completing a single production cycle. Throughout the production process, the actions of each station are linked by the rotation and positioning of the drive motor 1 and the extension and retraction signals of the cylinder 5, realizing continuous automated operation of feeding, unloading, heat sealing and film cutting, and material removal.

[0026] In some embodiments, the film feeding and receiving assembly includes a film feeding roller 12, which is located on one side of the film cutting cylinder 9. A heat-sealing film 28 is wound on the film feeding roller 12. A first synchronous pulley 14 is fixedly connected to one end of the film feeding roller 12. A synchronous belt 16 is wound around the first synchronous pulley 14. A second synchronous pulley 15 is also wound around the inner wall of the synchronous belt 16. A one-way component is provided at the second synchronous pulley 15. The one-way component is used to control the second synchronous pulley 15 to rotate in one direction according to the extension and retraction of the cylinder 5. The film take-up and take-up assembly also includes a take-up roller 11. The end of the heat-sealing film 28 on the film release roller 12 away from the film release roller 12 is wound around the take-up roller 11. One end of the take-up roller 11 is fixedly connected to a third synchronous pulley 13. The outer circular surface of the third synchronous pulley 13 is wound around the inner wall of the synchronous belt 16. Both ends of the film release roller 12 and the take-up roller 11 are rotatably connected to a support frame 32. The lower end of the support frame 32 is fixedly connected to a base 33. The one-way component includes a control plate 18. One side of the control plate 18 has multiple sets of evenly distributed grooves 19 from top to bottom. Each set of grooves 19 is rotatably connected to a ratchet 20. A second spring 21 is fixedly connected between the upper end of the ratchet 20 and the upper inner wall of the groove 19. A ratchet 17 is engaged with one side of the ratchet 20. The ratchet 17 is fixedly connected to the second synchronous pulley 15. A fixing rod 22 is fixedly connected between the control plate 18 and the pressure plate 6.

[0027] In this embodiment, the control plate 18 is fixedly connected to the pressure plate 6 via the fixing rod 22, ensuring that the control plate 18 and the pressure plate 6 always maintain synchronous lifting and lowering. When the cylinder 5 retracts after completing the heat sealing and film cutting process, driving the pressure plate 6 to move upward, the control plate 18 moves upward accordingly. The ratchet 20 in its groove 19 is engaged with the ratchet 17 under the preload of the second spring 21, and the rotation angle of the ratchet 20 is limited by the inner wall of the groove 19, preventing it from swinging in the opposite direction. Therefore, the upward-moving ratchet 20 drives the ratchet 17 to rotate in a preset direction. The ratchet 17 is fixedly connected to the second synchronous pulley 15, thereby driving the second synchronous pulley 15 to rotate synchronously. The second synchronous pulley 15 transmits power to the first synchronous pulley through the synchronous belt 16. The first synchronous pulley 14 and the third synchronous pulley 13, because the arrangement of the three synchronous pulleys on the synchronous belt 16 meets the transmission ratio matching requirements, make the film feeding roller 12 fixed to the first synchronous pulley 14 and the film taking roller 11 fixed to the third synchronous pulley 13 rotate synchronously, and the rotation speed is adapted to the shrinking stroke of the cylinder 5. The length of the new heat-sealing film 28 released by the film feeding roller 12 is exactly equal to the length of the waste film with circular holes recovered by the film taking roller 11, ensuring that the heat-sealing film 28 is always in a taut state and the conveying position is accurate. Both ends of the film feeding roller 12 and the film taking roller 11 are rotatably connected to the base 33 through the support frame 32. The support frame 32 provides stable support for the roller body, ensuring that its rotation is smooth and without jamming, and further ensuring the continuity of the film feeding and taking action.

[0028] When cylinder 5 extends and drives pressure plate 6 downward, control plate 18 moves downward synchronously. After the meshing surface of ratchet 20 contacts ratchet 17, it is subjected to the reverse force of ratchet 17. This force overcomes the preload of second spring 21 and causes ratchet 20 to rotate into groove 19, thereby avoiding ratchet 17. At this time, ratchet 17 remains stationary, and second synchronous pulley 15, film feeding roller 12, and film receiving roller 11 do not rotate. Heat-sealing film 28 is stationary, providing a stable working surface for the cutting action of film cutting cylinder 9. This design converts the contraction stroke of cylinder 5 into the power for film feeding and receiving through the directional transmission characteristics of unidirectional components. No additional drive source is required, which simplifies the equipment structure and ensures the precise coordination between heat-sealing film 28 conveying and film cutting heat-sealing processes, realizing the automation of process linkage. At the same time, it avoids the erroneous movement of heat-sealing film 28 when cylinder 5 extends, ensuring processing accuracy.

[0029] In some embodiments, the membrane take-up and take-down assembly further includes a sleeve 24, which is made of a magnetic material. A connecting rod 23 is rotatably arranged inside the sleeve 24. One end of the connecting rod 23 away from the sleeve 24 is fixedly connected to the second synchronous pulley 15. Multiple sets of permanent magnets 25 are embedded and installed on the outer circular surface of the connecting rod 23 inside the sleeve 24. The attraction force of the multiple sets of permanent magnets 25 on the sleeve 24 is greater than the elastic force of a single second spring 21. A bracket 4 is fixedly connected to the end of the sleeve 24 away from the connecting rod 23, and the drive motor 1 and the cylinder 5 are both mounted on the bracket 4.

[0030] In this embodiment, the sleeve 24 in the membrane retraction assembly is fixedly installed by the bracket 4, and its position remains stationary. One end of the connecting rod 23 is fixedly connected to the second synchronous pulley 15, and the second synchronous pulley 15 is coaxially fixed with the ratchet 17. The other end of the connecting rod 23 is rotatably inserted into the sleeve 24. Multiple sets of permanent magnets 25 embedded in the outer surface of the connecting rod 23 form a magnetic attraction with the inner wall of the sleeve 24. The magnetic attraction force of the multiple sets of permanent magnets 25 on the sleeve 24 is greater than the elastic force of a single second spring 21. This force balance design provides a key guarantee for the stable operation of the unidirectional assembly. When the cylinder 5 extends... When the pressure plate 6 moves downward, the control plate 18 moves downward synchronously. After the ratchet 20 contacts the meshing surface of the ratchet 17, it is subjected to a reverse force. Due to the magnetic attraction of the permanent magnet 25 to the sleeve 24, the connecting rod 23 tends to remain stationary. Moreover, this magnetic attraction is greater than the preload of the second spring 21, allowing the ratchet 20 to smoothly overcome the elastic force of the second spring 21 and rotate into the groove 19 to avoid it. At this time, the ratchet 17 remains stable and stationary under the constraint of the magnetic attraction, thereby ensuring that the second synchronous pulley 15, the film feeding roller 12, and the film receiving roller 11 do not rotate, and the heat-sealing film 28 remains stationary. The cutting action of the film cutting cylinder 9 provides a stable working surface; when the cylinder 5 retracts after completing the heat-sealing and film-cutting process, driving the pressure plate 6 to move upward, the control plate 18 moves upward accordingly. The ratchet 20 resets under the preload of the second spring 21 and reliably engages with the ratchet 17. At this time, the driving force generated by the retraction of the cylinder 5 is transmitted to the control plate 18 through the fixed rod 22, and then converted into the force of the ratchet 20 driving the ratchet 17 to rotate. This driving force is greater than the magnetic attraction force of the permanent magnet 25 on the sleeve 24, and can overcome the magnetic attraction resistance to drive the ratchet 17, the second synchronous pulley 15 and the connecting rod 23 to rotate synchronously. The connecting rod 23 rotates smoothly inside the sleeve 24, and through the synchronous belt 16, it links the first synchronous pulley 14 and the third synchronous pulley 13 to achieve the synchronous action of the film feeding roller 12 releasing new heat-sealing film 28 and the film receiving roller 11 collecting waste film. This magnetic adsorption design not only enhances the static stability of the ratchet 17 through magnetic attraction when the cylinder 5 extends, avoiding accidental movement of the heat-sealing film 28 that would affect the cutting accuracy, but also ensures smooth triggering of the film feeding and receiving actions through reasonable matching of driving force and magnetic attraction when the cylinder 5 retracts, without the need for additional locking or driving structures, further simplifying the equipment linkage logic and improving process stability.

[0031] In some embodiments, an arc-shaped groove 26 is provided on the side wall of the movable column 7, and a slider 27 is slidably disposed in the arc-shaped groove 26. The end of the slider 27 away from the arc-shaped groove 26 is fixedly connected to the film cutting cylinder 9.

[0032] In this embodiment, the sidewall of the moving column 7 is provided with a spiral arc-shaped groove 26 along the circumference. One end of the slider 27 is embedded in the arc-shaped groove 26 and slides against the groove wall, while the other end is fixedly connected to the cutting cylinder 9, forming a conversion mechanism from linear motion to rotational motion. When the cylinder 5 extends and drives the pressure plate 6 to move downward, the pressure plate 6 first pushes the moving column 7 and the cutting cylinder 9 to move downward synchronously until the lower blade of the cutting cylinder 9 contacts the heat-sealing film 28 and adheres to the surface of the turntable 2. Then, the pressure plate 6 continues to move downward, squeezing the first spring 10 to compress and store energy. The elastic force of the first spring 10 acts on the cutting cylinder 9, providing pressure for cutting. At the same time, the continuous downward linear motion of the moving column 7 is transmitted to the slider 27 through the spiral guide structure of the arc-shaped groove 26. A circumferential force is generated on the slider 27, forcing the slider 27 to slide along the arc groove 26 and drive the cutting cylinder 9 to rotate around the axis of the moving column 7. Under the combined action of the axial pressure of the first spring 10 and the circumferential rotational force, the lower blade of the cutting cylinder 9 acts on the heat-sealing film 28 in a rolling cutting manner. Compared with simple axial pressure cutting, this design can effectively reduce the tensile deformation of the heat-sealing film 28, avoid burrs or tears in the cut, and at the same time reduce the pressure required for cutting, improve the flatness of the cut and the cutting efficiency. In addition, the sliding cooperation between the slider 27 and the arc groove 26 also constrains the movement of the cutting cylinder 9, ensuring that it can only extend and retract axially and rotate circumferentially along the moving column 7, avoiding deviation that leads to cutting misalignment, and further ensuring the cutting accuracy and the stability of the subsequent heat sealing process.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
