Description

Technical Field

[0001] This application relates to the technical field of paper box manufacturing equipment, and in particular to a large paper cup forming apparatus. Background Technology

[0002] Paper cups are widely used as disposable containers for serving cooked foods, such as cakes and other treats at conferences and tea breaks. Paper cups are typically formed using a molding process, where a paper sheet is pressed into shape using a combination of mortise and tenon molds. The mold cavity forms the outer contour of the desired paper cup.

[0003] Most paper cup machines on the market use a multi-station rotary table structure. After the paper is gripped, it is transported to each station by the rotary table. To improve forming efficiency, some paper cup machines have two identical rotary tables, with the forming mold placed between the two rotary tables. However, for the forming of some large paper cups, the double rotary table structure makes the entire forming device too large in lateral area and occupies too much space. Utility Model Content

[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Figure 1 and Figure 2 The structure of a large paper cup forming device is shown, including a worktable 1, two sets of feeding mechanisms 3, two sets of forming mechanisms 4, two sets of unloading mechanisms 6, and two sets of stacking mechanisms 5. A transfer assembly 2 is installed on the worktable 1. The transfer assembly 2 includes a turntable 21 and a driving component that drives the turntable 21 to rotate relative to the worktable 1. In this embodiment, the driving component is a servo motor. The turntable 21 rotates intermittently relative to the worktable 1 at a fixed angle of 90° under the drive of the servo motor.

[0020] Two sets of feeding mechanisms 3 are symmetrically arranged on both sides of the turntable 21, and two sets of forming mechanisms 4 are symmetrically arranged on the other two sides of the turntable 21. The feeding mechanism 3 and the forming mechanism 4 are arranged at intervals. The unloading mechanism 6 is placed on the side of the forming mechanism 4 away from the turntable 21, and the stacking mechanism 5 is placed on one side of the unloading mechanism 6.

[0021] See Figure 3 The forming mechanism 4 includes an upper mold 41, a lower mold 42, and a first driving member connected to the upper mold 41. The lower mold 42 is mounted on the worktable 1, and the upper mold 41 is positioned above the lower mold 42 and can be driven by the first driving member to move away from / near the lower mold 42. After the upper mold 41 and the lower mold 42 are closed, there is a cavity between them for forming the paper cup 8.

[0022] In this embodiment, the first driving component includes a third driving motor 43 and a dual-shaft worm gear reducer 44 connected to the third driving motor 43. Both output shafts of the dual-shaft worm gear reducer 44 are connected to a transmission arm 45. One end of the transmission arm 45 is hinged to a connecting rod 46, and one end of the connecting rod 46 is hinged to an upper mold 41. Simultaneously, the upper mold 41 is guided and slid on the frame. A crank-like transmission structure is used to drive the upper mold 41 to move vertically. At the same time, the dual-shaft worm gear reducer 44 allows the third driving motor 43 to synchronously control the mold-closing and parting actions of the two molding mechanisms 4.

[0023] Of course, in another embodiment, the first driving component can also be a cylinder 4212, a hydraulic cylinder or other linear propulsion component, and the two first driving components can drive one of the upper molds 41 synchronously or independently to achieve the mold opening and closing action.

[0024] See Figure 4 Each forming mechanism 4 also includes a follower component 421, which is mounted on the worktable 1. The follower component 421 includes a follower plate 4211 and a floating support connecting the follower plate 4211. The follower plate 4211 is housed in the cavity of the lower mold 42. In this embodiment, the floating support is a cylinder 4212, whose cylinder shaft 4213 is connected to the follower plate 4211. When the upper mold 41 moves towards the lower mold 42 in a mold-closing displacement, the upper mold 41 can abut against the follower plate 4211. As the upper mold 41 continues to close, it can push the follower plate 4211 to move synchronously downwards. The driving force of the upper mold 41 driving the follower plate 4211 must be greater than the holding force of the cylinder 4212 to achieve the displacement of the follower plate 4211. Simultaneously, the holding force of the cylinder 4212, combined with the downward driving force of the upper mold 41, clamps the center portion of the paper, reducing the paper's movement within the cavity during the forming process.

[0025] In another embodiment, the floating support can also be a spring, with one end of the spring abutting against the follower plate 4211 and the other end being a fixed point that can be connected to the worktable 1. When the mold is closed, the upper mold 41 is compressed against the elastic force of the spring itself, while providing a supporting force to the follower plate 4211 toward the side of the upper mold 41 to support the paper.

[0026] See also Figure 5 and Figure 6The feeding mechanism 3 includes a paper stacking rack 31 with a discharge port 311. After the paper sheets are stacked, they are placed on the paper stacking rack 31, with the discharge port 311 positioned below the bottom paper sheets. The feeding mechanism 3 also includes several suction cups 32 connected to a suction cup 32 base. An L-shaped connecting plate 34 is provided at the bottom of the suction cup 32 base. A slider 36 is mounted on one end face of the connecting plate 34 and is mounted on a slide rail 37. One end of the slide rail 37 is fixed to the worktable 1. At the same time, a second driving member 35 is hinged to the connecting plate 34. The second driving member 35 can drive the suction cup 32 base to move away from / near the discharge port 311, thereby gripping and discharging the paper sheets stacked on the paper stacking rack 31.

[0027] In this embodiment, the forming device further includes a synchronization component 7 installed at the bottom of the workbench 1. The synchronization component 7 is used to connect two sets of feeding mechanisms 3, including a first drive motor 71, a transmission component, a first transmission shaft 74, and a swing arm 75. The transmission component includes two synchronous pulleys 72 and a meshing synchronous belt 73, wherein one synchronous pulley 72 is connected to the first drive motor 71, and the other synchronous pulley 72 is connected to the first transmission shaft 74, thereby driving the first transmission shaft 74 to rotate through the transmission component. Two swing arms 75 are provided and installed at both ends of the first transmission shaft 74, and one end of the swing arm 75 is connected to a second drive component 35. The second drive component 35 is a transmission link 46, and both ends of the transmission link 46 are hinged to the swing arm 75 and the connecting plate 34, respectively, thereby enabling the first drive motor 71 to synchronously control the suction cups 32 of the two sets of feeding mechanisms 3 to achieve synchronous gripping of the paper sheet.

[0028] Of course, in another embodiment, the second driving member 35 can be a cylinder / hydraulic cylinder, which can drive the two sets of suction cups 32 to move synchronously or independently.

[0029] See also Figure 1 and Figure 7 The unloading mechanism 6 includes a moving component 61 and a receiving plate 62 connected to the moving component 61. The moving component 61 includes two sets of linear modules 611 arranged at intervals, a second drive shaft 612, and a second drive motor 613. The two ends of the second drive shaft 612 are respectively connected to the two sets of linear modules 611, thereby realizing the synchronous operation of the two sets of linear modules 611. The second drive motor 613 is connected to one of the linear modules 611, and thus controls the movement of the two sets of linear modules 611 through the second drive component 35.

[0030] The feeding mechanism 6 also includes movable plates 63 connected to both sides of the receiving plate 62. The two movable plates 63 are respectively installed on two sets of linear modules 611, thereby driving the receiving plate 62 to move horizontally through the two movable plates 63.

[0031] The stacking mechanism 5 includes a paper cup stacking rack 51 with stacking openings 511 for positioning and stacking the formed paper cups 8. In this embodiment, the paper cup stacking rack 51 has two stacking openings 511, and a rotary cylinder 52 is connected to the bottom of the paper cup stacking rack 51. The two stacking openings 511 are circumferentially spaced 180° around the rotation center of the rotary cylinder 52. The stacking mechanism 5 also includes a top material component fixed to the worktable 1. The top material component includes a top material cylinder 53 and a top material plate 531 connected to the top material cylinder 53. The top material plate 531 is positioned below one of the stacking openings 511.

[0032] When this forming device produces paper cups 8, the synchronization component 7 controls two sets of feeding mechanisms 3 to simultaneously grip the paper sheets. The turntable 21 has four circumferentially distributed transfer ports 211. When the paper sheet is gripped, the suction cup 32 passes through the transfer port 211 and is attracted to the bottom of the paper sheet. The paper sheet is separated through the discharge port 311. The gripped paper sheet is transferred to the transfer port 211 of the turntable 21. The transfer port has a limiting groove to limit the gripped paper sheet.

[0033] Subsequently, the turntable 21 rotates 90°, the forming mechanism 4 closes the mold, the upper mold 41 passes through the transfer port 211 and moves the paper sheet toward the lower mold 42, and at the same time the follower plate 4211 abuts against the bottom of the paper sheet and moves down synchronously with the upper mold 41 to close the mold.

[0034] After the paper cup 8 is formed, the follower plate 4211 resets and lifts the paper cup 8. At the same time, the upper mold 41 has a suction hole. The formed paper cup 8 is sucked up by the upper mold 41 as it moves upward through an external air pump. The suction structure of the upper mold 41 is existing technology in the industry and will not be described in detail. The receiving plate 62 can be moved between the forming mechanism 4 and the stacking mechanism 5 by the moving component 61. When the receiving plate 62 moves to the side of the forming mechanism 4, the suction hole in the upper mold 41 stops sucking air, and the paper cup 8 falls into the receiving port 621 of the receiving plate 62. The receiving plate 62 moves with the paper cup 8 to the side of the stacking mechanism 5. The ejector cylinder 53 is activated to push the paper cup 8 toward the stacking port 511 and realize the stacking of the paper cup 8. Among them, the four transfer ports 211 on the turntable 21 pass through the feeding mechanism 3 and the forming mechanism 4 in sequence and at intervals, realizing continuous feeding of paper sheets and continuous forming of paper cups to improve production efficiency.

[0035] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
