Description

Technical Field

[0001] This invention relates to the production of paper cups such as outer cups, and particularly to equipment for assembling inner cup sleeves. Background Technology

[0002] Paper cups or paper bowls and other paper containers (for ease of description, they can all be referred to as paper cups) are equipped with cup sleeves (i.e., outer sleeves) to make outer cups (such as hollow cups). Usually, the inner cup body (which is a regular paper cup) is made by a paper cup machine and then assembled with the cup sleeve.

[0003] The cup sleeve molds are arranged circumferentially on a cup sleeve turntable. The turntable rotates around a central axis (vertically oriented) to different stations to facilitate the production and transfer of cup sleeves. When the cup sleeve mold rotates with the turntable to the demolding station, the cup sleeve detaches from the mold and enters the assembly conveyor turntable. The assembly conveyor turntable then carries the cup sleeve, rotating it to facilitate subsequent assembly of the cup sleeve and inner cup. Ensuring the cup sleeve smoothly and stably detaches from the mold and enters the assembly conveyor turntable is crucial; otherwise, subsequent assembly will be affected.

[0004] In addition, after the inner cups are produced by the paper cup machine (and multiple machines can be used), they are transported to a cup stacking channel (such as a cup-flying pipe) for collection. Cups are stacked one on top of the other in the cup stacking channel, and then each cup is unloaded from the bottom of the stacking channel (executed by the unloading mechanism) to be connected to the cup sleeve. The spiral feeding mechanism is a common cup unloading structure, but relying solely on the spiral head (with spiral patterns) of the spiral feeding mechanism for unloading still results in unstable feeding (i.e., cup unloading), slow cup dropping speed, untimely cup separation, and difficulty in matching the overall machine speed. Furthermore, for some short cups with a small body height, spiral unloading is prone to cup tilting and instability. Additionally, uneven stacking of cups in the cup stacking channel above the spiral head, resulting in tilting or deviation, will also prevent the cups from being unloaded smoothly.

[0005] Therefore, the stability of the cup sleeve detaching downwards and the stability of the inner cup feeding will affect the assembly efficiency and the quality of the paper cup. Summary of the Invention

[0006] In view of the technical problems existing in the background art, the technical problem solved by the present invention is to provide an inner cup sleeve assembly and molding machine that makes the cup sleeve detach from the mold more smoothly and stably, and makes the inner cup body unloading more efficiently, quickly and stably.

For example, a first air outlet is provided on the lifting shaft, which is connected to a first air passage.

For example, the air outlet is set outward and downward.

The air outlet is the port of the oblique channel. The horizontal channel is connected to the oblique channel. A plug is provided at the outer port of the horizontal channel. The horizontal channel is located above the cup sleeve mold surface of the mold body.

[0015] In addition, a reset limiting mechanism is provided between the lifting shaft and the mold body or mounting base; for example, the reset limiting mechanism includes a limiting component, which is connected to the lower part of the lifting shaft and is positioned below the vertical channel; the limiting component adopts a limiting ring, and the limiting component is connected to the lifting shaft by a screw, which is connected to the lower port of the first air passage of the lifting shaft.

[0016] The feeding guide rod may also be additionally equipped with a blow-cup hole, for example, the blow-cup hole is set to blow air inward at an angle; for example, the feeding guide rod is connected to an air receiving seat, the air receiving seat is equipped with an air connector, the blow-cup hole is connected to the air connector, and the blow-cup hole is set on the inner side of the feeding guide rod; the cup body stacking channel is fixedly set relative to the spiral head and the feeding guide rod, the cup body stacking channel includes a cup cage rod and / or a channel tube, and there may also be a connecting and overlapping area between the feeding guide rod and the cup body stacking channel; the feeding guide rod includes a vertical section; the feeding guide rod adopts a vertical rod, and a conical head is set at the upper end of the vertical rod.

[0017] The cup feeding channel is located above the assembly conveyor turntable, which has a cup receiving port arranged circumferentially on it.

[0018] For example, the lifting support includes a lifting plate, with a spiral head positioned below the lifting plate.

[0019] The beneficial effects of this invention are as follows: The inner cup sleeve assembly and molding machine can detach the cup sleeve from the mold body of the cup sleeve turntable at the demolding station and place it into the assembly conveyor turntable below (such as its receiving port). At the inner cup unloading and assembly station, the inner cup can be fed into the assembly conveyor turntable (such as its receiving port) via a spiral unloading method, allowing the inner cup to assemble with the cup sleeve. Specifically, during cup sleeve demolding, the lifting shaft descends and drives the unloading limit ring downwards. The downward movement of the unloading limit ring also pushes the cup sleeve down for demolding. Furthermore, the cup sleeve is moved upwards onto the mold body, where it fits onto the cup sleeve mold surface. During this fitting process, the unloading limit ring can block and limit the cup sleeve from above, preventing over-transfer and avoiding the problem of the cup sleeve being too tight and difficult to separate from the mold body. Unloading is relatively smooth, efficient, and stable, with easy placement and avoiding problems such as skewing. The spiral head is mounted on the lifting bracket and moves up and down with it. This coordinated movement during cup output allows for rapid downward output of the cup, improving feeding efficiency and increasing the cup dropping speed. After descending, the spiral head can be fitted over the cup receiving opening (described below for receiving the cup) to ensure the cup is output downwards, enabling fast, efficient, and stable paper cup output. Therefore, this invention has significant substantive features and remarkable progress compared to existing technologies. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the implementation 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.

[0030] Referring to the accompanying drawings, an inner cup sleeve assembly and molding machine according to an embodiment of this invention includes a cup sleeve turntable 37 and an assembly conveying turntable 48. The cup sleeve turntable 37 is used to transfer the cup sleeve 33. The cup sleeve turntable 37 is equipped with a demolding station 23. At the demolding station 23, the cup sleeve 33 is demolded off the cup sleeve turntable 37. The cup sleeve turntable 37 is connected to the assembly conveying turntable 48 at the demolding station 23. The cup sleeve 33 that has been demolded off the cup sleeve turntable 37 will enter the assembly conveying turntable 48, which will then transfer the cup sleeve 33 and facilitate subsequent assembly with the inner cup body.

[0031] The assembly conveyor turntable 48 is equipped with an inner cup unloading and assembly station 71, where the inner cup body is unloaded into the outer casing for assembly. The inner cup unloading and assembly station 71 is equipped with a cup body spiral unloading mechanism 72, located above the assembly conveyor turntable 48. The cup body spiral unloading mechanism 72 outputs the cup body onto the assembly conveyor turntable 48 via a spiral unloading method.

[0032] The cup sleeve turntable 37 is equipped with a cup sleeve mold device 1. At the demolding station 23, the cup sleeve mold device 1 engages with the assembly conveyor turntable 48 below for demolding. When the cup sleeve mold device 1 rotates with the cup sleeve turntable 37 to the demolding station 23, the cup sleeve 33 is demolded from the cup sleeve mold device 1 and then enters the assembly conveyor turntable 48 (such as the cup receiving port 49) downwards. The cup sleeve mold device 1 includes a mold body 2, which has a cup sleeve mold surface 3. The cup sleeve 33 is fitted onto the cup sleeve mold surface 3 of the mold body 2. A cup unloading limiting ring 4 is provided above the cup sleeve mold surface 3. When the cup sleeve 33 is delivered from bottom to top onto the mold body 2, the cup sleeve 33 can be limited by the cup unloading limiting ring 4 to prevent the cup sleeve 33 from being too tight with the mold body 2.

[0033] The mold body 2 is equipped with a lifting shaft 5, which can be raised and lowered on the mold body 2. A corresponding guide component 26 (such as a copper bushing bearing 56) can be configured between the lifting shaft 5 and the mold body 2. The lifting shaft 5 is equipped with a rising return spring 6, which is used to return the lifting shaft 5 to its original position. When the lifting shaft 5 is pressed down by an external force in the paper cup production equipment, the rising return spring 6 will deform and store force. When the external force is withdrawn, the rising return spring will help the lifting shaft 5 to rise and return to its original position. The lifting shaft 5 is connected to the cup unloading limit ring 4, which will be driven to rise and fall by the lifting shaft 5. When unloading the cup sleeve 33, the lifting shaft 5 will descend and drive the unloading cup sleeve 33 to its original position. The cup limiting ring 4 moves downward, and the cup unloading limiting ring 4 also pushes the cup sleeve 33 down. In addition, the cup sleeve 33 is moved upward to the mold body 2, and the cup sleeve 33 will be placed on the cup sleeve mold surface 3. During the insertion process, the cup unloading limiting ring 4 can block and limit the cup sleeve 33 from above, preventing the cup sleeve 33 from being moved too far and preventing the cup sleeve 33 from being too tight and difficult to separate from the mold body 2. The cup sleeve mold device 1 is used for the production of outer cups (such as hollow cups). The cup sleeve mold device 1 is installed on the cup sleeve turntable 37. During the unloading process, the cup sleeve 33 can be pushed down by the cup unloading limiting ring 4. The unloading is relatively smooth, smooth and stable, and the cup sleeve is easy to fall into place, avoiding problems such as tilting.

[0034] The cup body spiral feeding mechanism 72 includes a cup body stacking channel 40 and a spiral head 41. The cup body stacking channel 40 is vertically arranged, and cups are nested one by one within it. It can be connected to a paper cup forming machine to directly send formed paper cups into the stacking channel, or pre-made cups can be placed into it. The spiral head 41 is connected and configured at the lower outlet of the cup body stacking channel 40. When each spiral head 41 rotates, it cooperates to output the cups at the lower end of the stacking channel 40 downwards for feeding. The spiral head 41 is usually a rotating body, and generally has spiral patterns (such as spiral grooves or spiral ridges), which is a mature technology. The spiral head 41 is set on the lifting bracket 29, and can move up and down together with the lifting bracket 29. During the output of the cups, the spiral head moves up and down in coordination, which can quickly output the cups downwards into place, improve feeding efficiency, and make the cup dropping speed relatively faster.

[0035] Furthermore, the lifting bracket 29 is also equipped with a transmission component 24, which is located at the demolding station 23. The transmission component 24 moves up and down with the lifting bracket 29. The transmission component 24 is located above the lifting shaft 5 (located at the demolding station 23). The transmission component 24 works together to drive the lifting shaft 5 to descend. When the transmission component 24 descends, it acts as an external force to press down and drive the lifting shaft 5 to descend. When the transmission component 24 rises and disengages from the lifting shaft 5, the external force is withdrawn and the lifting shaft 5 is raised and reset by the rising reset spring.

[0036] The transmission component 24 not only moves up and down with the lifting bracket 29 to drive the lifting shaft 5 to descend and cooperate with the cup sleeve 33 for demolding, but the spiral head 41 also moves up and down with the lifting bracket 29 to cooperate with the spiral feeding of the cup body, making the structure more ingenious.

[0037] The inner cup sleeve assembly molding machine can detach the cup sleeve 33 from the mold body 2 of the cup sleeve turntable 37 at the demolding station 23 and enter the assembly conveying turntable 48 below (such as its cup receiving port 49). At the inner cup unloading assembly station 71, the inner cup can be sent to the assembly conveying turntable 48 (such as its cup receiving port 49) by spiral unloading, so that the inner cup can be assembled with the cup sleeve 33. During the demolding of the cup sleeve 33, the lifting shaft 5 will descend and drive the cup sleeve limiting ring 4 to move downward. The downward movement of the cup sleeve limiting ring 4 will also push the cup sleeve 33 to fall and demold. In addition, the cup sleeve 33 is moved upward to the mold body 2 and will be placed on the cup sleeve mold surface 3. During the insertion process, the cup sleeve limiting ring 4 can block and limit the cup sleeve 33 from above, preventing the cup sleeve 33 from being moved too far and preventing the cup sleeve 33 from being too tight and difficult to separate from the mold body 2. The cup unloading is relatively smooth, successful and stable, and the cup sleeve falls into place easily, avoiding problems such as tilting. The spiral head 41 is installed on the lifting bracket 29. The spiral head 41 can move up and down together with the lifting bracket 29. During the process of outputting the cup, the spiral head 41 moves up and down in coordination, which can quickly output the cup downwards into place, improve the feeding efficiency, and the cup dropping speed is relatively faster. After the spiral head 41 descends, it can be fitted over the cup receiving opening 49 (described below, used to receive the cup) to ensure that the cup is output downwards into place, which can quickly, efficiently and stably output the paper cup.

[0038] Based on the above embodiments, the following optimizations or further explanations can be made.

[0039] For example, a feeding guide rod 42 is connected to the lower outlet of the cup stacking channel 40. The feeding guide rod 42 is arranged between the spiral heads 41, that is, the feeding guide rod 42 cooperates between the spiral heads 41 to guide the cups to be fed (dropped). The spiral heads 41 and the feeding guide rod 42 cooperate to form a cup discharge channel, which is connected to the lower outlet of the cup stacking channel 40. The cups in the cup stacking channel 40 will be output through the cup discharge channel (formed by the spiral heads 41 and the feeding guide rod 42). During the output process, each spiral head 41 rotates to output the cups, and the spiral heads 41... 1. During the cup output process, the feeding guide rod 42 assists in guiding the cup output, making the cup output more stable and less prone to tilting. This not only meets the output requirements of normal-sized cup holders but also adapts to the output requirements of short cups. In addition, the spiral head 41 and the feeding guide rod 42 are set on the lifting bracket 29. The spiral head 41 and the feeding guide rod 42 can move up and down together with the lifting bracket 29. During the cup output process, the spiral head 41 and the feeding guide rod 42 cooperate in moving up and down, which can quickly output the cup downward into place, improve the feeding efficiency, and make the cup drop speed relatively faster, the feeding relatively more stable, and the cup position relatively less prone to tilting.

[0040] During operation, the cups located in the cup stacking channel 40 are output downwards by the rotation of the spiral head 41. During the output process, the cups are guided by the feeding guide rod 42 to make the downward output of the cups more stable and less prone to tilting. This not only meets the output requirements of normal-sized cup holders, but also adapts to the output requirements of short cups. In addition, during the downward output of the cups, the spiral head 41 and the feeding guide rod 42 can descend together with the lifting bracket 29 to quickly output the cups downwards. Then the lifting bracket 29, the spiral head 41, and the feeding guide rod 42 rise and reset to transport the next cup, improving the feeding efficiency and the cup dropping speed is relatively faster. Moreover, after the spiral head 41 and the feeding guide rod 42 descend, they can be fitted over the cup receiving opening 49 (described below, used to receive the cups) to ensure that the cups are output downwards in place, enabling fast, efficient, and stable output of paper cups.

[0041] In this cup-feeding spiral mechanism 72, the spiral head 41 and the feeding guide rod 42 are designed to move vertically and vertically at the lower outlet of the cup stacking channel 40. The spiral head 41 and the feeding guide rod 42 work together to output the cups downwards from the stacking channel 40. The vertically mounted spiral head 41 and feeding guide rod 42 efficiently, quickly, and stably output the cups downwards from the stacking channel 40. During the downward output of the cups, the spiral head 41 and the feeding guide rod 42 descend together with the lifting bracket 29, quickly outputting the cups downwards and ensuring they are in place. During the output process, the feeding guide rod 42 guides the cups, making the downward output more stable and preventing the cups from tilting or tipping over. This mechanism not only meets the output requirements of normal-sized cup holders but also accommodates the output requirements of shorter cups.

[0042] For example, the lifting shaft 5 has a first air passage 7, and an air inlet 8 at its upper end, which is connected to the first air passage 7 to supply air for blowing. The mold body 2 has a second air passage 9, and the cup sleeve mold surface 3 has an air outlet 10, which is connected to the second air passage 9. The first air passage 7 and the second air passage 9 are connected, that is, the first air passage 7 and the second air passage 9 are interconnected to allow gas output for blowing. The air source (such as compressed air) is input from the air inlet 8, passes through the first air passage 7 and the second air passage 9, and is then output from the air outlet 10 to assist in blowing. When removing the cup sleeve 33, the lifting shaft 5 will descend and drive the cup removal limiting ring 4 to move down. The air outlet 10 on the mold body (cup sleeve mold surface 3) will also blow air (air blowing). The air outlet 10 blowing air and the cup removal limiting ring 4 pushing down work together to not only form an air layer between the cup sleeve 33 and the mold body, causing the cup sleeve 33 to separate from the mold body, but also the cup sleeve 33 will be pushed down when the cup removal limiting ring 4 moves down. With the air layer between the cup sleeve 33 and the mold body in a separated state, the cup sleeve will fall more smoothly and stably, and will not tilt, making it easier to fall into place.

[0043] The air inlet 8 is positioned upwards, and the transmission component 24 also has an air nozzle 25 for blowing air into the air inlet 8. The outlet 251 of the air nozzle 25 is positioned downwards, and the air nozzle 25 can face the air inlet 8. When the transmission component 24 descends and contacts the lifting shaft 5, the air nozzle 25 can smoothly connect with the air inlet 8 to blow air into and input the air inlet 8. Moreover, the transmission component 24 and the air nozzle 25 can be adapted to the lifting shafts 5 of multiple mold bodies 2 on the cup sleeve turntable 37. When the lifting shafts 5 stop one by one at the demolding station 23, only the transmission component 24 and the air nozzle 25 are needed to drive the descent and supply air. A buffer sealing ring block 31 (such as a rubber ring block) can be set at the upper end of the air nozzle 25 or the lifting shaft 5 (at the air inlet 8) to prevent air leakage during blowing and to buffer and reduce transmission collision noise.

[0044] The assembly conveyor turntable 48 is also equipped with a cup sleeve inner wall gluing station 73 and a shaping station 74. The inner cup unloading assembly station 71 is located between the cup sleeve inner wall gluing station 73 and the shaping station 74; the inner cup unloading assembly station 71 is located between the demolding station 23 and the shaping station 74. The cup sleeve inner wall gluing station 73 is equipped with a gluing device 75, which is used to apply glue to the inner wall of the cup sleeve 33 on the assembly conveyor turntable 48 (such as the cup ring 50). The gluing can be done by spraying glue or brushing glue. The shaping station 74 is equipped with a shaping device 76, which is used to press down and shape the inner cup placed in the cup sleeve 33. The gluing device 75 and the shaping device 76 are connected to the lifting bracket 29. The lifting bracket 29 drives the gluing device 75 and the shaping device 76 to move up and down together to cooperate with gluing and shaping. When the lifting bracket 29 moves up and down, it will drive the cup body spiral feeding mechanism 72 and the lifting shaft 5 in the mold body 2 of the cup sleeve mold device 1 to move up and down together.

[0045] For example, the gluing device 75 includes a glue-spinning box (such as a bottomed cylinder) and a glue-spinning shaft 78. The glue-spinning shaft 78 is connected to the glue-spinning box via a drive mechanism, and is also connected to a glue-spinning motor 79. The glue-spinning box has a glue outlet hole on its side wall. Glue is placed into the glue-spinning box. When the glue-spinning box is rotated by the glue-spinning motor 79 via the glue-spinning shaft 78, the glue inside the box is flung out through the glue outlet hole, applying the glue onto the inner wall of the cup sleeve 33. This results in a relatively good gluing effect, with gluing around the entire circumference, making it more even and resulting in a more secure connection between the inner cup and the cup sleeve 33. When the gluing device 75 descends, the glue-spinning box enters the cup sleeve 33; when it rises, it exits to await the next gluing operation. In addition, the gluing device 75 also includes a cup sleeve pressure plate 81. The cup sleeve pressure plate 81 is equipped with a first buffer return spring 82. The cup sleeve pressure plate 81 is connected to the lifting bracket 29. When the gluing device 75 descends, the cup sleeve pressure plate 81 will also apply pressure to the cup sleeve 33, pressing the cup sleeve 33 into place to ensure a uniform and stable gluing position. The first buffer return spring 82 allows the cup sleeve pressure plate 81 to buffer when applying pressure to the cup sleeve, avoiding damage to the cup sleeve. In addition, the lifting bracket 29 is also connected to a mounting plate 83. The glue-spinning motor 79 is mounted on the mounting plate 83. The glue-spinning shaft 78 is connected to the glue-spinning motor 79. The glue-spinning box is connected to the glue-brushing shaft. The cup sleeve pressure plate 81 is connected to the mounting plate 83. The glue-spinning box has an upward-open glue inlet. Above the glue inlet is a glue-applying tube 84, which is connected to the lifting bracket 29.

[0046] For example, the shaping device 76 includes a shaping pressure plate 85, which is equipped with a second buffer return spring. The shaping pressure plate 85 is connected to the lifting bracket 29. The shaping pressure plate 85 will rise and fall together with the lifting bracket 29. When it descends, the shaping pressure plate 85 can press the inner cup into place. When it rises, it will return to its original position and wait for the next shaping. The second buffer return spring can buffer the pressure when the shaping pressure plate 85 presses the inner cup, so as to avoid damaging the inner cup and the outer cup.

[0047] For example, the mold body 2 is connected to the mounting base 11. The mold body 2 has an inward step 12. The cup sleeve mold surface 3 is located on the lower side of the inward step 12, and the cup unloading limit ring 4 is located on the upper side of the inward step 12. This facilitates processing and ensures that the cup unloading limit ring 4 can smoothly limit and block the upper edge of the cup sleeve, allowing it to be smoothly pushed down. In addition, the mounting base 11 and / or the mold body 2 have a vertical channel 13. The lifting shaft 5 is configured in the vertical channel 13. A guide 26 (such as a copper bushing bearing 56) can be configured in the vertical channel 13 to ensure that the lifting shaft 5 can move up and down smoothly and stably. The lifting shaft 5 is connected to a connecting component 14 (such as a connecting piece, for example, a connecting block 27 and a connecting shaft 28). The cup unloading limit ring 4 is connected to the connecting component 14, and the cup unloading limit ring 4 is connected to the lifting shaft 5 through the connecting component 14. The mold body 2 or mounting base 11 is provided with a connecting part 22 for connecting the cup sleeve turntable 37. Only one set of the mold body 2 and other structures is shown on the cup sleeve turntable 37 in the figure, so that it can be installed and connected to the cup sleeve turntable 37, allowing the entire structure to rotate and stop at each station along with the cup sleeve turntable 37. For example, a rising return spring 6 is sleeved on the lifting shaft 5, and a spring seat 15 is provided on the lifting shaft 5. The rising return spring 6 is located between the spring seat 15 and the mounting base 11 or the mold body 2. The rising return spring 6 can be a compression spring.

[0048] For example, the cup sleeve mold surface 3 is located on the circumferential side (i.e., the circumferential position) of the mold body 2. The lifting shaft 5 has a first air passage 16, and the first air passage 7 is connected to the first air passage 16. The mold body 2 has a second air passage 17, and the second air passage 9 is connected to the second air passage 17. The first air passage 16 is connected to the second air passage 17. The first air passage 7 and the second air passage 9 are connected by the first air passage 16 and the second air passage 17. After the gas is input from the air inlet 8, it passes through the first air passage 7, the first air passage 16, the second air passage 17, and the second air passage 9 before being output from the air outlet 10. In the diagram, the first air passage 16 is located on the side of the lifting shaft 5, and the second air passage 17 is one port of the second air passage 9. When the first air passage 16 and the second air passage 17 are directly opposite each other, the air volume is maximized; when they are misaligned, the air volume is relatively smaller. Alternatively, an air passage space can be provided between the first air passage 16 and the second air passage 17 to ensure air volume during connection. Sealing rings can also be installed above and below the air passage space to prevent air leakage and improve the blowing effect. Further optimization is possible; the air outlet 10 can be angled outwards and downwards, which not only facilitates manufacturing but also helps to blow the cup sleeve downwards, making the cup sleeve fall more stably and quickly. For example, the first air passage 7 includes a vertical channel 18, and the second air passage 9 includes a horizontal channel 19 and an oblique channel 20 that is angled downwards and outwards. The air outlet 10 is the port of the oblique channel 20. The horizontal channel 19 is connected to the oblique channel 20. The structure is compact, the layout is reasonable, and it is easy to process. The air passages can be set and connected by making holes (such as drilling), which is more practical and convenient. Among them, the outer port of the horizontal channel 19 is provided with a plug 21, and the horizontal channel 19 is located above the cup sleeve mold surface 3 of the mold body 2.

[0049] As an additional optimization, a reset limiting mechanism 34 is provided between the lifting shaft 5 and the mold body 2 or the mounting base 11. When the lifting shaft 5 is raised and reset under the action of the rising reset spring 6, the reset limiting mechanism 34 cooperates to limit the position of the lifting shaft 5, so that the operation is relatively more stable and reasonable. The lifting shaft 5 can be raised and reset without the rising reset spring 6 fully restoring. The stroke of the lifting shaft 5 can be relatively short. For example, the reset limiting mechanism 34 includes a limiting component 35, which is connected to the lower part of the lifting shaft 5 and is positioned below the vertical channel 13. During the lifting shaft 5's upward reset process, the limiting component 35 will rise along with it until it is blocked by the vertical channel 13 and is stopped by the lower port of the vertical channel 13. For example, the limiting component 35 can be a limiting ring, and the limiting component 35 can be connected to the lifting shaft 5 by a screw 36. The screw 36 is connected to the lower port of the first air passage 7 of the lifting shaft 5. The installation is relatively convenient and the structure is compact. The screw 36 can not only connect the limiting component 35 for installation, but also seal one port (lower end) of the first air passage 7 to form an air passage.

[0050] For example, the feeding guide rod 42 is also equipped with a cup-blowing hole. The cup-blowing hole is set to blow air inward and downward at an angle, forming a centering shape. The downward blowing not only keeps the cup relatively centered but also provides a downward blowing effect, making the downward output and conveying of the cup more stable. For example, the feeding guide rod 42 is connected to an air receiving seat 45, which is equipped with an air connector 46. The cup-blowing hole is connected to the air connector 46, which is used to connect the air source to supply the cup-blowing hole. The cup-blowing hole is located on the inner side of the feeding guide rod 42, that is, facing the cup-discharge channel, which can assist in blowing the cup in the cup-discharge channel. The air receiving seat 45 and the feeding guide rod 42 can be equipped with corresponding air passages that are connected. The air connector 46 connects to the air passages, and the cup-blowing hole serves as the port of the air passage.

[0051] The cup stacking channel 40 is fixedly installed relative to the spiral head 41 and the feeding guide rod 42. The cup stacking channel 40 includes a cup cage rod and / or a channel tube, which can be installed on a fixed frame. The raising and lowering of the spiral head 41 and the feeding guide rod 42 can also vibrate and shake the cups in the cup stacking channel 40, tidying up the cups in the cup stacking channel 40, making the cups relatively neat, and facilitating subsequent output. In addition, there is a connecting and overlapping area between the feeding guide rod 42 and the cup stacking channel 40. That is, the upper end of the feeding guide rod 42 extends into the lower end of the cup stacking channel 40, intersecting and overlapping. The feeding guide rod 42 can extend into the cup stacking channel 40. When the cups in the cup stacking channel 40 are not output from the lower end outlet, they can be guided by the feeding guide rod 42, making the cup output connection smoother. The side of the cup stacking channel 40 is provided with a side opening 59 and a side door (not shown) for opening and closing, so that the cup can be taken out from the side opening 59 in case of failure.

[0052] In addition, the feeding guide rod 42 includes a vertical section that can be used to form a cup feeding channel, which will smoothly guide the cup body downwards. The feeding guide rod 42 can be a vertical rod with a conical head 47 at the upper end. The structure is relatively simple, and the conical heads 47 are distributed around it, which can smoothly introduce and guide the cup body into the cup feeding channel.

[0053] The cup dispensing channel is equipped with a cup receiving port 49 below it for receiving cups, which can be used for the production of outer cups, etc. The cup dispensing channel is located above the assembly conveyor turntable 48. The assembly conveyor turntable 48 is equipped with cup receiving ports 49, which are arranged circumferentially on the assembly conveyor turntable 48. The cup receiving ports 49 form a circumferential circle. The spiral head 41 and the dispensing guide rod 42 are arranged above the assembly conveyor turntable 48. The assembly conveyor turntable 48 can be used for the production of outer cups, etc., and can also be used for inspection, etc. The cup receiving opening 49 is located on the cup receiving ring 50, which is mounted on the assembly conveyor turntable 48. The cup receiving ring 50 (i.e., the cup receiving seat) can be replaced to allow for changes in the size and specifications of the cup receiving opening 49, accommodating cups of different sizes. Furthermore, the cup receiving ring 50 has a certain height and thickness, requiring a certain amount of clearance for the assembly conveyor turntable 48 to rotate. This prevents interference between the cup receiving ring 50 and the rotating head and unloading guide rod 42 during rotation. The rotating head and unloading guide rod 42 rise and fall together with the lifting bracket 29, perfectly filling the clearance. To meet the requirements, when the assembly conveyor turntable 48 rotates and its cup receiving ring 50 (with a cup receiving opening 49) stops directly below the cup stacking channel 40 and the cup dispensing channel, the spiral head 41 and the dispensing guide rod 42 will descend with the lifting bracket 29 to output one cup downwards. After one cup is output, the spiral head 41 and the dispensing guide rod 42 will rise with the lifting bracket 29, and the assembly conveyor turntable 48 will continue to rotate, with another cup receiving ring 50 (with a cup receiving opening 49) stopping directly below the cup stacking channel 40 and the cup dispensing channel, and so on. After the spiral head 41 and the dispensing guide rod 42 descend, they can be fitted over the cup receiving ring 50 (with a cup receiving opening 49) to ensure that the cup is output downwards in place, enabling fast, efficient, and stable output of paper cups.

[0054] For example, the lifting bracket 29 includes a lifting plate 51, and a spiral head 41 is arranged below the lifting plate 51. The lifting plate 51 has a cup feeding space 52, through which a cup feeding channel and / or a cup stacking channel 40 passes. The cup feeding space 52 adopts a cup feeding opening.

[0055] The feeding guide rod 42 is adjustable in position forward and backward along the direction towards the cup dispensing channel; the spiral head 41 is also adjustable in position forward and backward along the direction towards the cup dispensing channel. This allows for radial adjustment of the relative positions of the feeding guide rod and spiral head towards the center of the cup dispensing channel to accommodate different cup sizes.

[0056] For example, the feeding guide rod 42 is mounted on the guide rod seat 53, which is mounted on the lifting bracket 29. The guide rod seat 53 is adjusted in position back and forth in the direction toward the cup feeding channel. As another example, the spiral head 41 is mounted on the support seat 54, which is mounted on the lifting bracket 29. The support seat 54 is adjusted in position back and forth in the direction toward the cup feeding channel.

[0057] For example, the spiral head 41 is connected to the rotating shaft 55, which is connected to the bearing 56. The bearing 56 is mounted on the support seat 54, which supports the rotation of the rotating shaft 55. The bearing 56 allows the rotating shaft 55 to rotate smoothly, which in turn drives the spiral head 41 to rotate. The rotating shaft 55 is vertically positioned, and the support seat 54 is connected to the lifting bracket 29. The rotating shaft 55 is also equipped with a transmission wheel 57, which is connected to the drive motor 58. The transmission wheel 57 can be a pulley with a belt drive structure (a tensioning transition wheel 60 can be additionally configured). In addition, the bearing 56 is located at the upper end of the rotating shaft 55, the spiral head 41 is located at the lower end of the rotating shaft 55, and the transmission wheel 57 is located between the bearing 56 and the spiral head 41. The support seat 54 is located on the upper side of the lifting bracket 29, and the spiral head 41 is positioned below the lifting bracket 29. The lifting bracket 29 uses a lifting plate 51.
