Description

Technical Field

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

[0002] With the development of industrial technology, modern industrial technology is paying more and more attention to automated production, and modern people are paying more and more attention to hygiene. Disposable paper cups, paper bowls or paper buckets are used in public places or gatherings to avoid the multiple use of a single paper cup, paper bowl or paper bucket. However, the demand for disposable paper cups and paper bowls is relatively large during gatherings, and it is difficult to meet the large-scale demand if disposable paper cups, paper bowls or paper buckets are processed manually.

[0003] Chinese patent announcement number CN204585954U discloses a single-rotor paper cup machine, including a cup cylinder forming mechanism, a cup bottom forming and upper bottom mechanism, and a paper cup forming mechanism. The paper cup forming mechanism includes an intermittently rotating turntable with a paper cup forming mold on it. The cup cylinder forming mechanism includes an ultrasonic cup cylinder forming device with a cup rim lubrication device. The cup cylinder forming mechanism is connected to the turntable via a flipping cup-loading device. The cup bottom forming and upper bottom mechanism includes a cup bottom forming and upper bottom device that directly delivers the formed cup bottom to the bottom of the cup cylinder on the paper cup forming mold. Although this paper cup machine can automate production and replace traditional manual processing, it still has the following drawbacks:

[0004] 1. The drive devices of each forming mechanism in this paper cup machine are installed separately at the bottom of the frame. The components of the drive device have a complex structure at the bottom of the frame and occupy a lot of space, which makes installation and maintenance extremely inconvenient and increases the labor intensity of the user.

[0005] 2. The paper suction mechanism of this paper cup machine is vertical, which makes the paper feeding speed slow and the suction is prone to picking up two sheets at the same time, resulting in low production efficiency. Summary of the Invention

[0006] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of this invention is to provide a compact, modularly assembled single-disc paper cup and bowl forming machine.

[0007] This invention is achieved through the following technical solution: a single-disc paper cup and bowl forming machine, comprising a paper suction mechanism, a paper feeding mechanism, a cup forming mechanism, a cup hooking mechanism, and a paper cup forming mechanism arranged in sequence. The paper cup forming mechanism includes a turntable, a main turntable grooved wheel box for driving the turntable to rotate intermittently, an edge rolling device, a bottom punching device, a bottom rolling device, and a cup flipping and cup lifting device. The turntable is provided with a paper cup forming mold and also includes a base. The base is respectively provided with an edge-adhesive cam box for driving the cup forming mechanism, a bottom rolling cam box for driving the bottom rolling device, and a main motor for driving the linkage of each mechanism.

[0008] Preferably, the cup forming mechanism of the present invention includes a leaf-sealing device and an ultrasonic welding device.

[0009] Preferably, the paper suction mechanism of the present invention includes a paper suction base, a material rack and an inlet for feeding paperboard into the paper suction base on one side, a first rotating shaft inside the paper suction base, a first fixed swing arm on the first rotating shaft, an intermediate rotating shaft rotatably connected to the first fixed swing arm, a movable plate on the intermediate rotating shaft, a suction head for adsorbing paper on the side of the movable plate facing the inlet, a second fixed swing arm for pushing the movable plate to swing and a connecting rod for pushing the second fixed swing arm to rotate inside the paper suction base, one end of the connecting rod being rotatably connected to the second fixed swing arm, and the other end of the connecting rod being provided with an eccentric wheel, one end of the second fixed swing arm being rotatably connected to the movable plate, and the other end of the second fixed swing arm being rotatably connected to a second rotating shaft, the second rotating shaft being rotatably mounted on the paper suction base.

[0010] Preferably, the movable plate of the present invention has at least one suction head mounting plate on one side for fixing the suction head, and the suction head is mounted on the suction head mounting plate.

[0011] Preferably, the material rack of the present invention is disposed inside the inlet, and there are multiple material racks, each distributed at equal intervals around the inlet.

[0012] Preferably, the material rack of the present invention is mounted on the paper suction seat by an adjusting seat. The adjusting seat is tightened on the paper suction seat by an adjusting nut. The adjusting seat is provided with a strip hole. One side of the strip hole is provided with a slot that passes through one end of the adjusting seat, and the end is provided with a positioning port for positioning the material rack. The material rack is fixed in the positioning port and is tightened to the other side of the adjusting seat by a screw passing through the slot from one side of the adjusting seat.

[0013] Preferably, the main turntable Geneva wheel box of the present invention includes a Geneva wheel box body, in which a rotatable input shaft and an output shaft are disposed. The axes of the input shaft and the output shaft are arranged perpendicularly. The input shaft is provided with a Geneva wheel for driving the output shaft to rotate. The Geneva wheel is provided with a guide groove arranged radially, and the two sides of the guide groove are curved surfaces. One end of the output shaft is provided with a power disk, and the other end is used to connect to a paper cup turntable. The lower end face of the power disk is provided with a power head for driving the Geneva wheel. There are multiple power heads, and the power heads are adapted to the guide groove so that the Geneva wheel drives the power disk to rotate when it rotates.

[0014] Preferably, the input shaft of the present invention is provided with a first bearing, and the first bearing is fixed to the Geneva wheel housing by a first end cover.

[0015] Preferably, the output shaft of the present invention is provided with a second bearing and a third bearing. The second bearing is fixed to the grooved wheel housing by a second end cover, and a third end cover for fixing the power disk is provided at one end of the output shaft.

[0016] Preferably, the grooved wheel housing of the present invention is provided with an inspection port, and the inspection port is provided with a side cover.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] 1. This invention adopts modular assembly, which makes the overall structure compact and occupies less space, which is conducive to expanding the scale of the production line and allowing more paper cup production equipment to be arranged in the same factory, thereby increasing the production line capacity. At the same time, the disassembly and maintenance of the main mechanisms are more convenient, which helps to reduce the maintenance cost of the equipment.

[0019] 2. The paper suction mechanism of this invention adopts multi-stage rotation. When the suction head picks up the cardboard, the suction head mounting plate and the feed port can be in parallel feeding trajectory. When the first fixed swing arm rotates to the limit position of the first rotating shaft, the movable plate rotates around the second fixed swing arm in an arc and flips, so that the suction head mounting plate flips with the movable plate and releases the paper on the suction head onto the paper feeding mechanism of the forming machine. Since the front feeding trajectory is parallel after the suction head picks up the cardboard, and the rear feeding trajectory is in an arc trajectory, the cardboard is less likely to get stuck at the lower edge of the discharge port, reducing friction and wear between the cardboard and the material rack, and improving work efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Reference Figures 1 to 8 As shown, a single-disc paper cup and bowl forming machine includes a paper suction mechanism 1, a paper feeding mechanism 2, a cup forming mechanism 3, a cup hooking mechanism 4, and a paper cup forming mechanism 5 arranged in sequence. The paper cup forming mechanism 5 includes a turntable 50, a main turntable grooved wheel box 51 for driving the turntable 50 to rotate intermittently, an edge rolling device 52, a bottom punching device 53, a bottom rolling device 54, and a cup flipping and cup lifting device 55. The turntable 50 is provided with a paper cup forming mold 56. Of course, the paper cup forming mechanism 5 also includes other devices such as cup bottom preheating and cup bottom knurling, which are all prior art, so they will not be described in detail here.

[0041] The aforementioned paper cup and bowl forming machine also includes a base 6, on which are respectively provided a sticking cam box 30 for driving the cup forming machine 3, a rolling cam box 540 for driving the rolling device 54, and a main motor 7 for driving the linkage of each mechanism. The sticking cam box 30 and the rolling cam box 540 are both modularly assembled, making the overall structure of the forming machine compact, occupying little space, and greatly improving the convenience of installation and maintenance.

[0042] The cup forming mechanism 3 mentioned above includes a leaf-sealing device 30 and an ultrasonic welding device 31. Both the leaf-sealing device 30 and the ultrasonic welding device 31 are existing technologies, and will not be described in detail here.

[0043] In this embodiment, the paper suction mechanism 1 includes a paper suction base 10. A material rack 11 and an inlet 110 for feeding paperboard are provided on one side of the paper suction base 10. A first rotating shaft 12 is provided inside the paper suction base 1. A first fixed swing arm 13 is provided on the first rotating shaft 12. An intermediate rotating shaft 14 is rotatably connected to the first fixed swing arm 13. A movable plate 15 is provided on the intermediate rotating shaft 14. A suction head 16 for adsorbing paperboard is provided on the side of the movable plate 15 facing the inlet 110. The paper suction base 10 also includes a second fixed swing arm 17 for pushing the movable plate 15 to swing and a connecting rod 18 for pushing the second fixed swing arm 17 to rotate. One end of the connecting rod 18 is rotatably connected to the second fixed swing arm 17, and the other end of the connecting rod 18 is provided with an eccentric wheel 19. One end of the second fixed swing arm 17 is rotatably connected to the movable plate 15, and the other end of the second fixed swing arm 17 is rotatably connected to the second rotating shaft 170. The second rotating shaft 170 is rotatably mounted on the suction seat 1. When the suction head picks up the cardboard, the suction head mounting plate and the feed port can be in parallel feeding trajectory. When the first fixed swing arm rotates to the limit position of the first rotating shaft, the movable plate rotates around the second fixed swing arm in an arc and flips, so that the suction head mounting plate flips with the movable plate and releases the paper on the suction head onto the paper feeding mechanism of the forming machine. Since the front feeding trajectory is parallel after the suction head picks up the cardboard, and the rear feeding trajectory is in an arc trajectory, the cardboard is less likely to get stuck at the lower edge of the discharge port, reducing friction and wear between the cardboard and the material rack, and improving work efficiency.

[0044] In addition, to ensure that the suction head can smoothly transfer the cardboard to the paper feeding mechanism, at least one suction head mounting plate 160 is provided on one side of the movable plate 15 for fixing the suction head 16. The suction head 16 is mounted on the suction head mounting plate 160. One or more suction heads 16 can be used. Preferably, in this embodiment, there are two suction heads 16, each fitted with one suction head mounting plate 160, with the two suction heads 16 distributed on both sides of the cardboard. Of course, the suction head mounting plate 160 can also be adjusted left and right on the movable plate to suit a better installation position and to be able to hold cardboard of different sizes.

[0045] In this embodiment, the material rack 11 is located inside the feed inlet 110, which is fan-shaped. There are multiple material racks 11, and each material rack 11 is distributed at equal intervals around the feed inlet 110, so that the paper can be placed more firmly on the material rack.

[0046] In this embodiment, the material rack 11 is mounted on the paper suction holder 10 via an adjusting seat 111. The adjusting seat 111 is tightened onto the paper suction holder 10 via an adjusting nut. Since the material rack 11 can adjust the size of the inlet 110 by adjusting the adjusting seat 111 to accommodate paper of different sizes, the adjusting seat 111 is provided with a strip hole 112. An adjusting screw passes through the strip hole and is tightened onto the paper suction holder 10. The strip hole design makes it easier to adjust the position. One side of the strip hole 112 is provided with a slot 113 that passes through one end of the adjusting seat 111, and this end is provided with a positioning port 114 for positioning the material rack 11. The material rack 11 is fixed in the positioning port 114 and is tightened onto the other side of the adjusting seat 111 via a screw passing through the slot 113 from one side of the adjusting seat 111.

[0047] In this embodiment, the main turntable Geneva wheel box 51 includes a Geneva wheel box body 511. A rotatable input shaft 512 and an output shaft 513 are disposed within the Geneva wheel box body 511. The axes of the input shaft 512 and the output shaft 513 are perpendicularly arranged. A Geneva wheel 514 for driving the output shaft 513 to rotate is provided on the input shaft 512. The Geneva wheel 514 is provided with radially arranged guide grooves 515, at least two of which are curved on both sides. One end of the output shaft 513 is provided with a power disk 516, and the other end is used to connect to the paper cup turntable. The lower end face of the power disk 516 is provided with a power head 517 for driving the grooved wheel 514. There are multiple power heads 517, and each power head 517 is evenly distributed along the circumference of the power disk 516. The power head 517 is adapted to the guide groove 515. When the input shaft drives the grooved wheel 514 to rotate, the grooved wheel 514 pushes the power head to drive the power disk to rotate, thereby causing the output shaft on the power disk to rotate.

[0048] In this embodiment, the input shaft 512 is provided with a first bearing 5120. There are two first bearings 5120, one of which is located at one end of the input shaft, and the other is located between the two ends of the input shaft. Both first bearings 5120 are fixed to the Geneva wheel housing 511 by the first end cover 5121, so that the input shaft 512 can rotate in the Geneva wheel housing 511 under the drive of the motor.

[0049] In this embodiment, the output shaft 513 is provided with a second bearing 5130 and a third bearing 5131. The second bearing 5130 is fixed to the Geneva wheel housing 511 by a second end cover 5132. A locking nut 519 for fixing the second bearing 5130 to the Geneva wheel housing 511 is provided between the second bearing 5130 and the second end cover 5132. One end of the output shaft 513 is provided with a third end cover 5133 for fixing the power disk 516. The third end cover 5133 is located between the third bearing 5131 and the power disk 516.

[0050] In this embodiment, the Geneva wheel housing 511 is provided with an inspection port 5110, and the inspection port 5110 is provided with a side cover 518. Since the components inside the Geneva wheel housing 511 are lubricated by lubricating oil, the mechanical transmission is more stable. Therefore, the side cover 518 can be removed to inspect the inside of the Geneva wheel housing through the inspection port to check whether the lubricating oil has decreased, etc.

[0051] In addition, to facilitate the further assembly of the internal components of the Geneva wheel housing, the upper end of the Geneva wheel housing is open, and a detachable top cover 5111 is provided at the opening. The top cover 5111 can be fastened to the Geneva wheel housing 511, making it easy to disassemble and assemble.

[0052] 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.
