Description

Technical Field

[0001] This application belongs to the field of paper cup machines, and particularly relates to an automatic paper feeding system with automatic rotation and positioning for a paper cup machine. Background Art

[0002] A paper cup machine is an automated device that processes paper roll raw materials into paper cups through continuous processes. Its core processes include die cutting, forming, bottom sealing, etc. In the die cutting process, the paper roll is cut into paper pieces of a specific shape (i.e., die-cut paper patterns). Subsequently, the paper feeding system needs to convey these paper patterns to the forming station in sequence. The paper feeding systems of existing paper cup machines usually adopt a fixed bin structure that is fixed to the paper cup machine frame, and drive the die-cut paper patterns to move along a preset path through gears, chains, conveyor belts or pneumatic devices, so that the die-cut paper patterns reach the bin outlet for the paper picking mechanism to grab. Such bins have a small paper capacity and often require manual replenishment of an appropriate amount of die-cut paper patterns from auxiliary appliances such as transport flatbed carts into the bin, which seriously reduces the paper feeding efficiency. Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide an automatic paper feeding system with automatic rotation and positioning for a paper cup machine to solve the technical problem of low paper feeding efficiency of paper cup machines in the prior art.

[0004] To achieve the above purpose, the technical solution adopted in this application is: to provide an automatic paper feeding system with automatic rotation and positioning for a paper cup machine, including: A turntable; A lead screw, coaxially arranged with the turntable; A nut seat, threadedly connected to the lead screw; A platform, connected to the nut seat and used for carrying the target die-cut paper pattern; A guide rod, connected to the turntable and arranged parallel and spaced apart from the lead screw, and the platform is movably sleeved on the guide rod and slidably connected to the guide rod; A first servo motor, drivingly connected to the lead screw and used for driving the lead screw to rotate around the central axis; A second servo motor, drivingly connected to the turntable and used for driving the turntable to rotate around the central axis, and the second servo motor is also communicatively connected to the first servo motor and can make the turntable and the lead screw rotate synchronously.

[0005] Optionally, the automatic paper feeding system with automatic rotation and positioning for a paper cup machine further includes a column connected to the platform and a paper supporting table connected to the column and used for supporting the target die-cut paper pattern; The column extends in a direction parallel to the axial direction of the lead screw, and a plurality of the paper supporting tables are arranged at intervals along the extending direction of the column.

[0006] Optionally, a plurality of groups of the upright posts and the paper supporting table are arranged at intervals around the central axis of the lead screw.

[0007] Optionally, a plurality of groups of the guide rods are arranged at intervals around the central axis of the lead screw.

[0008] Optionally, the automatic paper feeding system with automatic indexing of the paper cup machine further includes a sliding bearing connected to the platform; the sliding bearing is sleeved on the guide rod in a sliding manner, and the platform forms a sliding connection with the guide rod through the sliding bearing.

[0009] Optionally, the automatic paper feeding system with automatic indexing of the paper cup machine further includes a worm and worm gear box; The worm and worm gear box includes a worm gear coaxially connected to the turntable and a worm drivingly connected to the worm gear, and the second servo motor is drivingly connected to the worm so that the output shaft of the second servo motor is perpendicular to the output shaft of the first servo motor.

[0010] Optionally, the lead screw penetrates through the turntable and the worm gear and can rotate relative to the turntable and the worm gear.

[0011] Optionally, the automatic paper feeding system with automatic indexing of the paper cup machine further includes a vehicle for convenient movement and a mobile power source installed on the vehicle; The turntable, the lead screw, the nut seat, the platform, the guide rod, the first servo motor and the second servo motor are all arranged on the vehicle, and the mobile power source is electrically connected to the first servo motor and the second servo motor respectively.

[0013] Optionally, the automatic paper feeding system with automatic indexing of the paper cup machine further includes a handle connected to the vehicle.

[0014] The beneficial effects of the automatic indexing paper feeding system for a paper cup machine provided in this application are as follows: Compared with the prior art, in the automatic indexing paper feeding system for a paper cup machine provided in this application, when the first servo motor drives the lead screw to rotate, the nut seat threadedly connected to the lead screw can drive the platform to move along the axial direction of the lead screw, and the guide rod parallel to the lead screw can ensure the linear displacement accuracy of the platform by slidingly connecting with the platform; when the second servo motor drives the turntable to rotate, the guide rod rotates synchronously with the turntable, forcing the platform to rotate around the axis of the lead screw. At this time, the first servo motor and the second servo motor are controlled through communication linkage, so that the lead screw and the turntable can rotate at the same speed and in the same direction. At this time, the axial displacement generated by the rotation of the lead screw of the nut seat is offset in real time by the reverse displacement of the platform caused by the rotation of the turntable. Finally, the platform maintains its axial position unchanged during the rotation process. Therefore, the automatic indexing paper feeding system for a paper cup machine 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, so as to flexibly adapt to the position change of the paper picking mechanism, and thus achieve a higher paper feeding efficiency, which is far superior to the prior art.

[0022] Please refer to Figures 1 to 3 , and a description will now be given of an automatic indexing paper feeding system for a paper cup machine provided by an embodiment of the present application. The automatic indexing paper feeding system for the paper cup machine 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. Among them: 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 in parallel and at an interval with the lead screw 102, and the platform 104 is movably sleeved on the guide rod 105 and is slidably connected to the guide rod 105; the first servo motor 106 is drivingly 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 drivingly 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 make the turntable 101 and the lead screw 102 rotate synchronously. Here, the guide rod 105 is used to accurately guide the axial sliding of the platform 104 and at the same time is used to transmit the rotational power of the turntable 101 to the platform 104 to drive the platform 104 to rotate.

[0023] According to the above structure provided in this embodiment, in the automatic indexing paper feeding system of 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 threadedly connected to the lead screw 102 can drive the platform 104 to move axially along the lead screw 102, so that the paper supporting table 109 reaches the set height position; and the guide rod 105 parallel to the lead screw 102 can ensure the linear displacement accuracy of the platform 104 through the sliding connection with the platform 104; when the second servo motor 107 drives the turntable 101 to rotate, the guide rod 105 rotating synchronously with the turntable 101 will force the platform 104 to rotate around the axis of the lead screw 102, so that the paper supporting table 109 rotates circumferentially to the 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 generated by the rotation of the lead screw 102 of the nut seat 103 is offset in real time by the reverse displacement of the platform 104 caused by the rotation of the turntable 101, and finally the platform 104 maintains a constant axial position during the rotation. Therefore, the automatic indexing paper feeding system of the paper cup machine provided in this application can enable the platform 104 to independently adjust the rotation angle or the axial height, and can maintain a constant height during rotation, so as to flexibly adapt to the position change of the paper taking mechanism, and thus a higher paper feeding efficiency can be achieved, which is far superior to the prior art.

In this way, the paper support tables 109 at different height levels can be accurately moved to the same grasping position of the paper grasping mechanism of the paper cup machine in sequence, so that the paper grasping mechanism can continuously grasp multiple layers of paper patterns. This not only reduces the occupation of equipment space, but also can achieve uninterrupted paper supply by preloading multiple layers of paper patterns, thereby greatly shortening the paper material replacement time, which is beneficial to further improving the paper supply efficiency of the automatic indexing paper supply system of the paper cup machine in this embodiment.

In this way, each group of paper support tables 109 can follow the rotation of the platform 104 and reach the same grasping position in sequence. The paper grasping mechanism can continuously obtain the target die-cut paper patterns 200 at different workstations without moving, and this can also achieve uninterrupted paper supply by preloading multiple groups of target die-cut paper patterns 200, which is also beneficial to further improving the paper supply efficiency of the automatic indexing paper supply system of the paper cup machine in this embodiment.
