Description

Technical Field

[0001] This invention relates to the field of paper cup machine technology, specifically to a double-plate paper cup, bowl, and bucket forming machine. Background Technology

[0002] Disposable paper containers such as paper cups, paper bowls, and paper buckets are widely used in the catering and packaging industries. Manual processing of disposable paper cups, bowls, or buckets is insufficient to meet large-volume demands. Therefore, single-disc paper cup forming machines have emerged on the market. Their workflow typically includes multiple processes such as paper suction, feeding, cup / bowl bonding, cup bottom cutting, cup bottom rolling, preheating, bottom folding, knurling, and cup rim curling. Furthermore, because all forming processes are completed on the same turntable in a single-disc paper cup forming machine, the following drawbacks exist:

[0003] 1. Most of the process devices and drive components are installed separately without modular division, resulting in a loose overall structure, large equipment size, large footprint, and low workshop space utilization. At the same time, the separate structure makes it difficult to disassemble and maintain the equipment. When a single component fails, the entire machine needs to be disassembled extensively, resulting in long downtime for maintenance and affecting production efficiency.

[0004] 2. Traditional paper cup forming machines are mostly single-disc structures, with all processes concentrated on a single turntable. The number of workstations is limited, and there is waiting time in the process flow, resulting in a slow production cycle and low efficiency, making it difficult to meet the needs of large-volume, high-efficiency production.

[0005] Therefore, there is an urgent need for a double-plate paper cup, bowl, and bucket forming machine with optimized structure, convenient maintenance and disassembly, and higher efficiency to overcome the shortcomings of existing technologies. Summary of the Invention

[0044] Reference Figures 1 to 5 As shown, a double-disc paper cup / bowl forming machine includes a base 1 and multiple independent functional modules detachably mounted on the base 1. The functional modules include: a cup-sticking module 2, a cup-flipping and cup-topping mechanism 3, a bottom-punching device 4, a bottom-rolling device 5, a main turntable module 6, and a rim-rolling disc module 7. It also includes independently configured drive components, including a main turntable grooved wheel box A and a rim-rolling grooved wheel box B. The main turntable module 6 and the rim-rolling disc module 7 form a double-disc workstation structure. The main turntable module 6 is independently driven by the main turntable grooved wheel box C, and the rim-rolling disc module 7 is independently driven by the rim-rolling grooved wheel box D. Each functional module and drive component is an independently detachable unit structure, cooperating with a standardized interface and transmission mechanism to complete the paper cup forming process. The main turntable module 6 and the rim-rolling disc module 7 operate synchronously. The main turntable continuously completes the processing of the cup cylinder and cup bottom, while the rim-rolling disc continuously completes the rim-rolling process. The two processes operate in parallel, achieving high-efficiency continuous production.

[0045] The cup-sticking module 2 integrates a paper-absorbing component E, a paper-feeding component F, an adhesive component G, and a cup-hooking component H to form an independent cup-sticking unit. The main turntable module 6 is equipped with a preheating component I, a bottom-folding component J, and a knurling component K. The mouth-rolling module 7 is equipped with a mouth-rolling component L. Each component is integrated with its corresponding module and can be assembled and disassembled as a whole. The bottom-rolling device 5 rolls and shapes the cup bottom, while the knurling component K knurls and reinforces the cup bottom. The preheating component I preheats and softens the cup blank, improving the sealing and stability of the cup bottom formation.

[0046] During operation, the paper suction component E picks up the cup body sheet from the material pile, the paper feeding component F conveys the sheet to the adhesive component G for glue application, and the glued sheet is then hooked into a cup cylinder blank by the cup cylinder hooking component H and sent into the main turntable module 6.

[0047] The main turntable Geneva wheel box A and the bead-rolling Geneva wheel box B are independent drive units, respectively fixed on the base 1. The output end of the main turntable Geneva wheel box A is connected to the main turntable module 6, and the output end of the bead-rolling Geneva wheel box B is connected to the bead-rolling plate module 7. The main turntable module 6 is driven by the main turntable Geneva wheel box A to achieve intermittent rotation. The main turntable of the main turntable module 6 has cup-sticking station, cup-topping station, bottom-punching station, and bottom-rolling station distributed circumferentially. When the cup blank is fed into the main turntable, the processes of cup-sticking, cup-topping, bottom-punching, and bottom-rolling are completed in sequence.

[0048] In other words, the main turntable grooved wheel box A and the main turntable module 6, as well as the bead grooved wheel box B and the bead plate module 7, are all connected by a detachable transmission, which can be disassembled, repaired or replaced separately without affecting the operation of other modules.

[0049] The rim rolling plate module 7 is a second turntable independent of the main turntable module 6, and it is driven by the rim rolling groove wheel box N to achieve intermittent rotation. The cup blank with the bottom formed is transferred from the main turntable module 6 to the rim rolling plate module, where the rim is rolled and shaped to achieve a smooth and rounded rim.

[0050] The cup-flipping and cup-topping mechanism includes a cup-flipping assembly, a cup-topping assembly, and a housing 11. The cup-flipping assembly and the cup-topping assembly are both integrated and installed inside the housing 11, and they are linked together through the same power shaft 12. The cup-flipping assembly includes a cup-flipping cam 13, a cup-flipping swing arm 14, a cup-flipping transmission assembly 15, and a cup-flipping rigid shaft 16. The cup-flipping cam 13 is fixed on the power shaft 12 and is driven by the cup-flipping swing arm 14, the cup-flipping transmission assembly 15, and the cup-flipping rigid shaft 16 to realize the flipping action of the paper cup. The cup-topping assembly includes a cup-topping cam 17, a cup-topping upper swing arm 170, a cup-topping lower swing arm 171, a cup-topping transmission assembly 18, and a cup-topping rigid shaft 172. The cup-topping cam 17 is fixed on the power shaft 12 and is driven by the cup-topping upper swing arm 170, the cup-topping lower swing arm 171, the cup-topping transmission assembly 18, and the cup-topping rigid shaft 172 to realize the ejection action of the paper cup. All transmission components of the top cup assembly and the flipping cup assembly are enclosed inside the housing 11. Only the input end of the power shaft and the execution ends of the top cup and the flipping cup extend outside the housing. The power shaft 12 simultaneously drives the top cup cam 17 and the flipping cup cam 3. The contour curves of the two are matched, so that the timing of the top cup action and the flipping cup action are synchronized and the action is connected smoothly.

[0051] In this embodiment, the cup-flipping transmission assembly 15 further includes a first cup-flipping connecting rod 150 and a second cup-flipping connecting rod 151. The cup-flipping cam 13 drives the second cup-flipping connecting rod 151 to drive the cup-flipping mold 152 to complete the flipping action through the cup-flipping swing arm 14, the first cup-flipping connecting rod 150, and the cup-flipping hard shaft 16 in sequence.

[0052] Specifically, one end of the cup-flipping rigid shaft 16 is hinged to one end of the first cup-flipping connecting rod 150, the other end of the cup-flipping rigid shaft 16 is hinged to one end of the second cup-flipping connecting rod 151, the other end of the first cup-flipping connecting rod 150 is hinged to one end of the cup-flipping swing arm 14, and the other end of the second cup-flipping connecting rod 151 drives the cup-flipping mold 152.

[0053] In this embodiment, the top cup transmission assembly 18 further includes a first top cup connecting rod 173 and a second top cup connecting rod 174, and a top cup connecting rod swing arm 175 hinged between the first top cup connecting rod 173 and the second top cup connecting rod 174. The top cup cam 17 drives the top cup rigid shaft 172 to perform linear reciprocating motion through the top cup upper swing arm 170, the top cup lower swing arm 171, the first top cup connecting rod 173, the top cup connecting rod swing arm 175, and the second top cup connecting rod 174 in sequence, thereby completing the ejection action of the paper cup. The top cup connecting rod swing arm 175 can improve the stability of the transmission and reduce the movement gap.

[0054] The top cup connecting rod swing arm 175 is connected to a hinge seat 176 at one end away from the second top cup connecting rod 174. The hinge seat 176 is connected to the housing 11 via a rotating shaft. The second top cup connecting rod 174 is also provided with a fixed seat 177. One end of the first top cup connecting rod 173 is hinged to the fixed seat 177, and the other end is hinged to the top cup upper swing arm 170. The housing 11 is also provided with a track 110. The track 110 is provided with a slider 111 that slides with it. The top cup rigid shaft 16 is fixed to the slider 111. One end of the second top cup connecting rod 173 is hinged to the slider, and the other end of the second top cup connecting rod 173 is hinged to one end of the top cup connecting rod swing arm 175, thereby making the linear reciprocating motion of the top cup rigid shaft 172 more stable.

[0055] The cup-flipping swing arm 14, the upper cup swing arm 170, and the lower cup swing arm 171 are connected to the housing 11 via a swing arm support shaft 19. The swing arm support shaft 19 provides rotational support for the cup-flipping swing arm 14, ensuring the smoothness of the flipping action.

[0056] Working principle of the cup-flipping and cup-topping mechanism: When the paper cup forming machine is working, the power shaft 12 is driven to rotate by an external drive device, and the cup-topping cam 17 and the cup-flipping cam 13 rotate synchronously with the power shaft 12. When the paper cup forming machine horizontally conveys the cup film to the cup-flipping mold 18, the cup-flipping cam 13 drives the cup-flipping swing arm 14 to swing through the contour curve. After being transmitted by the cup-flipping transmission assembly 15, it drives the second cup-flipping connecting rod 151 to drive the cup-flipping mold 152 to rotate. The cup-topping cam 17 drives the upper cup-topping swing arm 170 and the lower cup-topping swing arm 171 to swing through the contour curve. After being transmitted by the cup-flipping transmission assembly 18, it drives the cup-topping hard shaft 172 to move upward, pushing the formed paper cup out of the mold. The pushed-out paper cup is moved to the next process station. After the cup-flipping action is completed, the cup-topping hard shaft 172 is reset, and the cup-flipping assembly continues to operate, repeating the cycle to complete continuous operation.

[0057] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
