Description

Technical Field

[0001] This application belongs to the field of paper cup machines, and particularly relates to an automatic paper feeding system for paper cup machines. Background Technology

[0002] A paper cup machine is an automated device that processes paper rolls into paper cups through a continuous process. Its core processes include die-cutting, forming, and sealing. The die-cutting process cuts the paper rolls into paper pieces of specific shapes (i.e., die-cut patterns), and then the paper feeding system sequentially conveys these patterns to the forming station. Existing paper cup machine feeding systems typically use a fixed hopper structure integrated with the machine frame. Gears, chains, conveyor belts, or pneumatic devices drive the die-cut patterns along a preset path, allowing them to reach the hopper outlet where the paper-feeding mechanism picks them up. These hoppers have a small paper capacity, requiring frequent manual replenishment from transport carts or similar auxiliary equipment. This significantly reduces feeding efficiency. Therefore, it is necessary to solve these technical problems. Summary of the Invention

[0003] The purpose of this application is to provide an automatic paper feeding system for a paper cup machine, so as to solve the technical problem of low paper feeding efficiency in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide an automatic paper feeding and rotation system for a paper cup machine, comprising:

[0005] Turntable;

[0006] The lead screw is coaxially arranged with the turntable;

[0007] Nut seat, threadedly connected to the lead screw;

[0008] The platform is connected to the nut seat and is used to carry the target die-cut paper pattern;

[0009] A guide rod is connected to the turntable and spaced parallel to the lead screw; the platform is movably fitted onto the guide rod and slidably connected to the guide rod.

[0010] A first servo motor is connected to the lead screw drive and is used to drive the lead screw to rotate around the central axis;

[0011] The second servo motor is connected to the turntable and drives the turntable to rotate around the central axis. The second servo motor is also communicatively connected to the first servo motor and enables the turntable and the lead screw to rotate synchronously.

[0012] Optionally, the paper cup machine automatic paper feeding system further includes a column connected to the platform and a paper support table connected to the column and used to support the target die-cut paper sample.

[0013] The column extends in a direction parallel to the axial direction of the lead screw, and several paper receiving platforms are spaced apart along the extension direction of the column.

[0014] Optionally, multiple sets of the column and the paper receiving platform are arranged at intervals around the central axis of the lead screw.

[0015] Optionally, multiple sets of guide rods are arranged at intervals around the central axis of the lead screw.

[0016] Optionally, the automatic paper feeding system for the paper cup machine further includes a sliding bearing connected to the platform; the sliding bearing is slidably mounted on the guide rod, and the platform is slidably connected to the guide rod through the sliding bearing.

[0017] Optionally, the automatic paper feeding system for the paper cup machine also includes a worm gear box;

[0018] The worm gear box includes a worm gear coaxially connected to the turntable and a worm gear drivenly connected to the worm gear. The second servo motor is drivenly connected to the worm gear so that the output shaft of the second servo motor is perpendicular to the output shaft of the first servo motor.

[0019] Optionally, the lead screw passes through the turntable and the worm gear and is rotatable relative to the turntable and the worm gear.

[0020] Optionally, the paper cup machine automatic paper feeding system also includes a mobile carrier and a mobile power supply installed on the carrier;

[0021] The turntable, the lead screw, the nut seat, the platform, the guide rod, the first servo motor, and the second servo motor are all mounted on the carrier, and the mobile power supply is electrically connected to the first servo motor and the second servo motor respectively.

[0022] Optionally, the bottom of the vehicle is provided with electrically driven wheels, which are electrically connected to the mobile power source.

[0023] Optionally, the paper cup machine's automatic paper feeding system also includes a handle connected to the carrier.

[0024] The beneficial effects of the automatic paper feeding system for paper cup machines provided in this application are as follows: Compared with the prior art, in the automatic paper feeding system for paper cup machines provided in this application, when the first servo motor drives the lead screw to rotate, the nut seat threaded to the lead screw can drive the platform to move along the lead screw axis, while the guide rod parallel to the lead screw can ensure the linear displacement accuracy of the platform by sliding connection with the platform; when the second servo motor drives the turntable to rotate, the guide rod rotates synchronously with the turntable, which will force the platform to rotate around the lead screw axis. At this time, the first servo motor and the second servo motor are controlled by communication linkage, which can make the lead screw and the turntable rotate at the same speed and in the same direction. At this time, the axial displacement of the nut seat caused by the rotation of the lead screw is canceled in real time by the reverse displacement of the platform caused by the rotation of the turntable, so that the platform maintains a constant axial position during rotation. Therefore, the automatic paper feeding system for paper cup machines provided in this application can enable the platform to independently adjust the rotation angle or axial height, and can maintain a constant height during rotation, thereby flexibly adapting to the position changes of the paper picking mechanism, thus achieving higher paper feeding efficiency, which is far superior to the prior art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] Please refer to the following: Figures 1 to 3 This application describes an automatic paper feeding and rotation system for a paper cup machine. The system includes a turntable 101, a lead screw 102, a nut seat 103, a platform 104, a guide rod 105, a first servo motor 106, and a second servo motor 107.

[0035] The lead screw 102 is coaxially arranged with the turntable 101; the nut seat 103 is threadedly connected to the lead screw 102; the platform 104 is connected to the nut seat 103 and is used to carry the target die-cut paper pattern 200; the guide rod 105 is connected to the turntable 101 and is arranged parallel to and spaced apart from the lead screw 102, and the platform 104 is movably fitted on the guide rod 105 and slidably connected to the guide rod 105; the first servo motor 106 is drivenly connected to the lead screw 102 and is used to drive the lead screw 102 to rotate around the central axis; the second servo motor 107 is drivenly connected to the turntable 101 and is used to drive the turntable 101 to rotate around the central axis, and the second servo motor 107 is also communicatively connected to the first servo motor 106 and can enable the turntable 101 and the lead screw 102 to rotate synchronously. Here, the guide rod 105 is used to precisely guide the axial sliding of the platform 104, and also to transmit the rotational power of the turntable 101 to the platform 104 to drive the platform 104 to rotate.

[0036] According to the structure provided in this embodiment, in the automatic paper feeding system for the paper cup machine provided in this embodiment, when the first servo motor 106 drives the lead screw 102 to rotate, the nut seat 103 threaded to the lead screw 102 can drive the platform 104 to move axially along the lead screw 102, thereby causing the paper receiving platform 109 to reach the set height position; and the guide rod 105 parallel to the lead screw 102, through its sliding connection with the platform 104, can ensure the linear displacement accuracy of the platform 104; when the second servo motor 107 drives the turntable 101 to rotate... The synchronous rotation of the guide rod 105 with the turntable 101 forces the platform 104 to rotate around the axis of the lead screw 102, thereby causing the paper receiving table 109 to rotate circumferentially to a set position. At this time, the first servo motor 106 and the second servo motor 107 are controlled through communication linkage, so that the lead screw 102 and the turntable 101 can rotate at the same speed and in the same direction. At this time, the axial displacement of the nut seat 103 caused by the rotation of the lead screw 102 is offset in real time by the reverse displacement of the platform 104 caused by the rotation of the turntable 101, so that the platform 104 maintains a constant axial position during rotation. Therefore, the automatic paper feeding system for paper cup machines provided in this application allows the platform 104 to independently adjust its rotation angle or axial height, and can maintain a constant height during rotation, thereby flexibly adapting to the position changes of the paper picking mechanism. This achieves higher paper feeding efficiency, which is far superior to the prior art.

[0037] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The paper cup machine's automatic paper feeding system also includes a column 108 connected to the platform 104 and a paper support table 109 connected to the column 108 and used to support the target die-cut paper sample 200; the column 108 extends in a direction parallel to the axial direction of the lead screw 102, and several paper support tables 109 are arranged at intervals along the extension direction of the column 108.

[0038] According to the structure provided in this embodiment, when the first servo motor 106 drives the lead screw 102 to rotate, the nut seat 103 can drive the platform 104 and the column 108 to move along the axial direction of the lead screw 102. This allows the paper receiving platforms 109 of different height layers to move precisely to the same gripping position of the paper gripping mechanism of the paper cup machine in sequence. As a result, the paper gripping mechanism can continuously grip multiple layers of paper samples, which reduces the space occupied by the equipment and enables uninterrupted paper supply by preloading multiple layers of paper samples. This significantly shortens the paper material replacement time, which is beneficial to further improve the paper supply efficiency of the automatic paper feeding system of the paper cup machine in this embodiment.

[0039] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 Multiple sets of columns 108 and paper receiving platforms 109 are arranged at intervals around the central axis of the lead screw 102.

[0040] According to the structure provided in this embodiment, when the second servo motor 107 drives the turntable 101 to rotate, the platform 104 and the multiple sets of columns 108 and paper receiving tables 109 distributed around the lead screw 102 can also rotate around the lead screw 102. In this way, each set of paper receiving tables 109 can follow the platform 104 to rotate and reach the same gripping position in sequence. The paper gripping mechanism can continuously acquire the target die-cut paper samples 200 at different workstations without moving. In this way, uninterrupted paper supply can also be achieved by preloading multiple sets of target die-cut paper samples 200, which is also conducive to further improving the paper supply efficiency of the automatic paper feeding system of the paper cup machine in this embodiment.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 Multiple sets of guide rods 105 are spaced around the central axis of the lead screw 102. According to the structure provided in this embodiment, the multiple sets of guide rods 105 can not only improve the stability of the platform 104 moving along the axial direction of the lead screw 102, but also enable the platform 104 and the turntable 101 to rotate more synchronously, which is also conducive to further improving the paper feeding efficiency of the automatic paper feeding system of the paper cup machine in this embodiment.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The automatic paper feeding system for the paper cup machine also includes a sliding bearing 110 connected to the platform 104; the sliding bearing 110 is slidably mounted on the guide rod 105, and the platform 104 is slidably connected to the guide rod 105 through the sliding bearing 110. According to the structure provided in this embodiment, the sliding bearing 110 connected to the platform 104 can make the platform 104 slide more stably relative to the guide rod 105, which is also conducive to further improving the paper feeding efficiency of the automatic paper feeding system for the paper cup machine in this embodiment.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The automatic paper feeding system for the paper cup machine also includes a worm gear box 111. The worm gear box 111 includes a worm wheel 112 coaxially connected to the turntable 101 and a worm 113 drivenly connected to the worm wheel 112. A second servo motor 107 is drivenly connected to the worm 113 so that the output shaft of the second servo motor 107 is perpendicular to the output shaft of the first servo motor 106. According to the structure provided in this embodiment, the second servo motor 107 is drivenly connected to the turntable 101 through the worm gear box 111, which allows the power output shafts of the first servo motor 106 and the second servo motor 107 to be perpendicular to each other. This effectively avoids interference between their power transmission paths and ensures a compact space, which also helps to further improve the paper feeding efficiency of the automatic paper feeding system for the paper cup machine in this embodiment.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The lead screw 102 passes through the turntable 101 and the worm gear 112 and can rotate relative to the turntable 101 and the worm gear 112. According to the structure provided in this embodiment, the lead screw 102 passing through the turntable 101 and the worm gear 112 can be provided with rotational support by the turntable 101 and the worm gear 112. It can be understood that the part of the lead screw 102 passing through the turntable 101 and the worm gear 112 is a smooth rod, and is provided with a journal to be rotatably connected to the worm gear box 111 or the turntable 101 through a corresponding bearing, so that the lead screw 102 has a stable rotational support. This allows the lead screw 102 to rotate more stably and independently, which is also conducive to further improving the paper feeding efficiency of the automatic paper feeding system of the paper cup machine in this embodiment.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The automatic paper feeding system for the paper cup machine also includes a movable carrier 114 and a mobile power supply 115 mounted on the carrier 114. The turntable 101, lead screw 102, nut seat 103, platform 104, guide rod 105, first servo motor 106, and second servo motor 107 are all mounted on the carrier 114. The mobile power supply 115 is electrically connected to the first servo motor 106 and the second servo motor 107, respectively. According to the structure provided in this embodiment, the mobile power supply 115 mounted on the carrier 114 can provide power to the first servo motor 106 and the second servo motor 107. This allows the carrier 114 to easily move the paper feeding system formed by the turntable 101, lead screw 102, nut seat 103, platform 104, and guide rod 105. Therefore, the automatic paper feeding system for the paper cup machine provided in this embodiment can achieve higher paper feeding efficiency by better adapting to the paper taking mechanism.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The bottom of the carrier 114 is equipped with electrically driven rollers 116, which are electrically connected to a power source 115. According to the structure provided in this embodiment, the rollers 116, electrically connected to the power source 115, can be powered by the power source 115 to assist in the movement of the carrier 114. Their function is that, when this automatic paper cup machine paper feeding system is in use, it can also serve as a transport tool for the target die-cut paper sample 200. That is, after loading the target die-cut paper sample 200 onto the paper receiving table 109, it is transported from the warehouse to the paper cup machine feeding position. During this transportation process, the rollers 116 driven by the power source 115 provide assistance, significantly saving operator time. Furthermore, with the carrier 114 equipped with an IoT module, it can achieve autonomous displacement and precise positioning. It can move between the warehouse and the paper cup machine according to the needs of each paper cup machine host. After reaching the feeding position of the paper cup machine, it brakes or locks the carrier 114 at the set target position through a special positioning and locking mechanism. Then, the paper gripping mechanism on the paper cup machine can take the target die-cut paper sample 200 from the paper receiving table 109 and replenish it into the paper cup machine's feeding bin. This helps to further improve the paper feeding efficiency of the automatic paper feeding system of the paper cup machine in this embodiment. It is understood that in the specific implementation process, the roller 116 driven by the mobile power supply 115 in this embodiment can be a commonly used roller 116 in the art, and a commonly used power drive mechanism can also be provided between the roller 116 and the mobile power supply 115, which will not be elaborated further here.

[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3 The paper cup machine automatic paper feeding system also includes a handle 117 connected to the carrier 114. According to the structure provided in this embodiment, the handle 117 connected to the carrier 114 facilitates manual operation of the carrier 114 for movement, which is also conducive to further improving the paper feeding efficiency of the paper cup machine automatic paper feeding system in this embodiment.
