[0031] Please also read Figures 1 to 3 Now, a paper cup machine paper picking device provided in an embodiment of the present application is described. The paper cup machine paper picking device comprises a frame 101, a silo 103, a transfer component and a paper suction component. Among them:

[0032] The frame 101 forms a paper feed guide 102 for conveying die-cut paper cup blanks, and the hopper 103 forms an opening 104 facing the paper feed guide 102. The transfer assembly includes a support 105 mounted on the frame 101 and a rotating shaft 106 rotatably connected to the support 105 and used for reciprocating rotation, and also includes a driving arm 107 connected to the rotating shaft 106 and driven by the rotating shaft 106 to reciprocate and swing, and the support 105 is also connected to a first gear 108 whose central axis is parallel to the rotating shaft 106. The paper suction assembly includes a paper suction shaft 109 that is rotatable and passes through the driving arm 107, and a second gear 110 coaxially sleeved at the end of the paper suction shaft 109 and meshed with the first gear 108, and also includes a first suction cup 111 connected to the paper suction shaft 109 and used for sucking paper from the hopper 103, and the driving arm 107 has a predetermined swing range so that the first suction cup 111 is alternately facing the opening 104 or the paper feed guide 102.

[0033] According to the above structure provided in this embodiment, in the paper cup machine paper picking device provided in this embodiment, the rotating shaft 106 can reciprocate relative to the support 105 and drive the driving arm 107 connected to the rotating shaft 106 to swing back and forth. Since the first gear 108 is rotatably mounted on the support 105, the second gear 110 is rotatably mounted on the driving arm 107, and the second gear 110 and the first gear 108 are meshed with each other, the swing arm can drive the second gear 110 to reciprocate around the center of the first gear 108 during the reciprocating swing process, thereby driving the paper suction shaft 109 connected to the second gear 110 to reciprocate. When the reciprocating swing range of the driving arm 107 is fixed, the first suction cup 111 can be alternately opposite to the opening 104 of the silo 103 or the paper feeding guide 102. Since the aforementioned structures are rigidly connected, the suction cup can stably reciprocate and accurately align with the opening 104 of the silo 103 or the paper guide 102. The structure is simple and has stability and precision far superior to the prior art.

[0034] In another embodiment of the present application, please refer to Figures 1 to 3, the transfer assembly also includes an intermediate gear 112 rotatably connected to the driving arm 107, and the first gear 108 is indirectly meshed with the second gear 110 through the intermediate gear 112. According to the above structure provided in this embodiment, the intermediate gear 112 is provided between the first gear 108 and the second gear 110 to increase the center distance between the first gear 108 and the second gear 110, so that the suction shaft 109 connected to the second gear 110 can have a larger spacing with the paper feeding guide 102 and provide a larger rotation space for the first suction cup 111. In addition, by providing the intermediate gear 112 between the first gear 108 and the second gear 110, the rotation direction of the second gear 110 relative to the first gear 108 can be changed, so that the rotation direction of the second gear 110 and the swing direction of the driving arm 107 are consistent, which is conducive to more accurate control of the rotation range of the second gear 110 to improve the accuracy of the paper picking device of the paper cup machine in this embodiment.

[0035] In another embodiment of the present application, please refer to Figures 1 to 3 According to the above structure provided in this embodiment, the first gear 108 is set as a sector gear, which can not only make the second gear 110 rotate relative to the first gear 108 within a predetermined range, but also reduce the material consumption when preparing the first gear 108, thereby playing a role in energy saving and emission reduction.

[0036] In another embodiment of the present application, please refer to Figures 1 to 3 The frame 101 has a work table 113 parallel to the paper feed guide 102, and the transfer assembly includes a pull rod 114 that vertically penetrates the work table 113 and can reciprocate in a direction perpendicular to the work table 113. The end of the pull rod 114 is hinged with a first swing arm 115, and the end of the first swing arm 115 away from the pull rod 114 is hinged with a rocker 116, and the end of the rocker 116 away from the first swing arm 115 is hinged to the rotating shaft 106, and the pull rod 114 drives the rotating shaft 106 to reciprocate through the first swing arm 115 and the rocker 116. According to the above structure provided in this embodiment, the pull rod 114 that moves vertically relative to the work table 113 has better movement stability, so that the rotating shaft 106 can be driven to reciprocate stably, which is beneficial to the stability of the paper picking device of the paper cup machine in this embodiment. In addition, in this embodiment, the pull rod 114 and the rotating shaft 106 are also rigidly connected, so the accuracy of the reciprocating rotation range of the rotating shaft 106 can be effectively guaranteed.

[0037] In another embodiment of the present application, please refer to Figures 1 to 3The transfer assembly includes an eccentric shaft 117 which is parallel to the rotating shaft 106 and can rotate, and also includes a connecting plate 118 connected to the eccentric shaft 117 and a rocker arm 119 hinged to the connecting plate 118. One end of the rocker arm 119 is hinged to the frame 101 and driven by the connecting plate 118 to swing back and forth relative to the frame 101. The swing axis of the rocker arm 119 is parallel to the eccentric shaft 117. The end of the pull rod 114 away from the first swing arm 115 is hinged to the second swing arm 120, and the end of the second swing arm 120 away from the pull rod 114 is hinged to the rocker arm 119. According to the above structure provided in this embodiment, since the eccentric shaft 117 drives the connecting plate 118 to rotate with good precision, the rocker arm 119 connected to the connecting plate 118 can be driven to swing back and forth accurately. Since the end of the rocker arm 119 away from the frame 101 is connected to the connecting rod through the second swing arm 120, the connecting rod can be driven to move relatively stably relative to the working surface of the frame 101, which is beneficial to further improve the accuracy of the paper taking device of the paper cup machine in this embodiment.

According to the above structure provided in this embodiment, the second suction cup 121 can absorb the paper cup die-cut sample on the paper feed guide 102 through the through hole provided on the paper feed guide 102, which is conducive to improving the efficiency of transferring the paper cup die-cut sample from the first suction cup 111 to the paper feed guide 102 and improving the production efficiency of paper cups.

[0040] In another embodiment of the present application, please refer to Figures 1 to 3The transfer assembly further includes a driving mechanism that is transmission-connected to the second suction cup 121 and can move the second suction cup 121 toward or away from the paper feed guide 102 in a direction perpendicular to the paper feed guide 102. According to the above structure provided in this embodiment, after the paper cup die-cut sample is stably transferred to the paper feed guide 102, the second suction cup 121 can be moved away from the paper feed guide 102, so that the paper cup die-cut sample on the paper feed guide 102 can be more easily transported to the subsequent processing steps, which is conducive to further improving the paper picking efficiency of the paper picking device of the paper cup machine in this embodiment.

[0041] In another embodiment of the present application, please refer to Figures 1 to 3 , the second suction cup 121 and the first suction cup 111 are both transmission-connected to the eccentric shaft 117 so that the second suction cup 121 and the first suction cup 111 can move synchronously. According to the above structure provided in this embodiment, by setting the first suction cup 111 and the second suction cup 121 to be connected to the same eccentric shaft 117 and to be able to move synchronously, it is beneficial for the first suction cup 111 and the second suction cup 121 to better cooperate with each other, thereby further improving the paper picking efficiency of the paper picking device of the paper cup machine in this embodiment.
