Description

Technical Field

[0001] This utility model relates to the field of paper cup machine processing, and in particular to a paper material feeding device for a paper cup machine. Background Technology

[0002] A paper cup machine is a type of mechanical equipment specifically designed for producing paper cups. It processes paper materials into the shape of paper cups through a series of automated or semi-automated processes. A paper cup machine typically includes multiple parts such as a mechanical transmission system, a forming system, a heating system, and a control system. In order to ensure the continuity of production during the paper cup production process, a paper material feeding device is required.

[0003] The existing technology has the following drawbacks: Existing paper cup machines use vacuum suction cups to transfer paper sheets for processing. Due to differences in paper cup machine models, the operating angle of the vacuum suction cups varies. Traditional paper cup machine material feeding devices often lack flexibility in terms of feeding angle. Once installed, the feeding angle is difficult to adjust conveniently according to the diverse needs of different paper cup machine equipment. This leads to the risk of inaccurate feeding when facing different models and production process requirements of paper cup machines, affecting production efficiency and product quality. Furthermore, additional modifications or replacements are needed to meet the requirements, increasing costs and time investment. Secondly, traditional feeding devices also present many inconveniences in terms of installation and maintenance. When it is necessary to disassemble, repair, or replace the feeding platform and related feeding components, complex operating procedures and tools are often required. The device uses a large number of bolts for fixing, making disassembly not only time-consuming and labor-intensive but also reducing maintenance efficiency to a certain extent. Therefore, a paper cup machine material feeding device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a paper material feeding device for a paper cup machine, which aims to improve the problem that the existing technology cannot adapt to different operating angles of paper cup machine equipment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a paper material feeding device for a paper cup machine, including a conveyor table 1. The conveyor table 1 is an existing paper material conveying platform, composed of a conveyor belt, which will not be described in detail here. A support frame 2 is fixedly connected to the top of the conveyor table 1. The support frame 2 mainly supports and connects to the feeding platform 6. A connecting plate 3 is detachably installed at the top of the support frame 2. A fixing ring 4 is fixedly connected to the top of the connecting plate 3. A rotating shaft 5 is rotatably connected through the inner wall of the fixing ring 4. The middle part of the fixing ring 4 is hollow, which allows the rotating shaft 5 to rotate along the middle part of the fixing ring 4. The front end of the rotating shaft 5 is fixedly connected to an upper... The feeding platform 6 is the existing paper cup machine platform, mainly connecting and supporting the feeding rod 7. The feeding rod 7 is set at the top of the feeding platform 6. The feeding rod 7 is the feeding component of the existing paper cup machine. The feeding rod 7 can be adjusted independently to allow paper sheets to be stacked on the feeding rod 7, which is convenient for subsequent feeding operations. The inner wall of the rotating shaft 5 is fixedly connected to the guide rod 10. The length of the guide rod 10 is the same as the height of the groove of the rotating shaft 5, which allows the guide rod 10 to guide the wedge block 9. The wedge block 9 moves vertically and the movement trajectory will not deviate. The inner wall of the rotating shaft 5 is equipped with a limit mechanism, and the inner wall of the connecting plate 3 is equipped with a connecting component.

[0033] The limiting mechanism includes a wedge 9, which is slidably connected to the inner wall of the rotating shaft 5. The two sides of the wedge 9 are inclined. When the inclined surfaces are squeezed, the wedge 9 will slide along the inner wall of the rotating shaft 5. A pressing plate 11 is slidably connected to the outer wall of the wedge 9. The pressing plate 11 has a circular protrusion. The height of the circular protrusion is the same as that of the inclined surface of the wedge 9. If the circular protrusion is fully inserted into the rotating shaft 5, the inclined surface of the wedge 9 can be squeezed. In the initial state, the wedge 9 is fully inserted into the groove of the inner wall of the fixing ring 4, and the inclined surface cannot be squeezed at this time. The bottom end of the wedge 9 is elastically connected to the rotating shaft 5 through a return spring 8.

[0034] Reference Figure 1 , Figure 4 and Figure 5The connecting assembly includes a plug 12, which is inserted into the support frame 2 to initially position the connecting plate 3. The plug 12 is fixedly connected to the inner wall of the connecting plate 3. A movable plate 14 is elastically connected to the inner wall of the left end of the plug 12 via a positioning spring 13. A limit block 15 is fixedly connected to the right end of the movable plate 14. The limit block 15 is inclined. When the inclined surface is compressed, the limit block 15 will move the movable plate 14. The inner wall of the left end of the plug 12 is fixedly connected to one end of the positioning spring 13. When the movable plate 14 moves to the left, it will compress the positioning spring 13. When resetting, the elastic force of the positioning spring 13 will move the movable plate 14. The movable plate 14 is reset, and the other end of the positioning spring 13 is fixedly connected to the left end of the movable plate 14. The movable plate 14 is slidably connected to the inner wall of the insert block 12. The insert block 12 has a corresponding slot for the movable plate 14, which can satisfy the lateral movement of the movable plate 14. The limiting block 15 is slidably connected to the inner wall of the insert block 12. The limiting block 15 is inserted into the inner wall of the support frame 2. The inner wall of the support frame 2 has a corresponding slot for the limiting block 15, which can satisfy the unidirectional limiting of the entire connecting plate 3 by the insertion of the limiting block 15. The insert block 12 is inserted into the top of the support frame 2. The support frame 2 has a corresponding slot for the insert block 12.

[0035] Reference Figure 1 - Figure 3 The bottom end of the wedge 9 is fixedly connected to one end of the return spring 8. When the wedge 9 moves downward, it will compress the return spring 8. When resetting, the elastic force of the return spring 8 will carry the wedge 9 to reset. The other end of the return spring 8 is fixedly connected to the inner wall of the top of the rotating shaft 5. The wedge 9 is slidably connected to the outer wall of the guide rod 10. The wedge 9 is inserted into the inner wall of the fixing ring 4. The fixing ring 4 has a slot corresponding to the wedge 9, which can satisfy the angle positioning of the wedge 9 and its insertion into the rotating shaft 5 and the loading platform 6. The pressing plate 11 passes through and is slidably connected to the inner wall of the rotating shaft 5.

[0036] Working principle: First, when the feeding platform 6 needs to be adapted to different feeding angles, simply press the pressing plate 11 to move the wedge 9 downwards and initially compress the return spring 8, allowing the inclined surface of the wedge 9 to be squeezed by the inner wall groove of the fixing ring 4. For adjustment, simply rotate the rotating shaft 5 to rotate the feeding platform 6 and the feeding rod 7 counterclockwise, so that the feeding platform 6 and the feeding rod 7 are at the required feeding angle. When the rotating shaft 5 rotates, the inner wall groove of the fixing ring 4 will squeeze the inclined surface of the wedge 9, causing the wedge 9 to continue moving downwards while keeping the position of the pressing plate 11 unchanged. The wedge 9 continues to move downwards and compress the return spring 8. When the wedge 9 and the next inner wall groove of the fixing ring 4 coincide, the reverse elastic force of the return spring 8 will cause the wedge 9 to return to its original position. When a limit is needed, simply release the pressing plate 11 and use the reverse elastic force of the return spring 8 to move the wedge 9 and the pressing plate 11 upwards to return to their original position, so that the wedge 9 is fully inserted into the inner wall groove of the fixing ring 4. This completes the adjustment of the feeding angle of the feeding platform 6 and the feeding rod 7, which can adapt to the feeding needs of different paper cup machine equipment. If you need to adjust again, you can follow the above steps.

[0037] When the entire loading platform 6 and feeding rod 7 need to be disassembled from the equipment, simply press the moving plate 14 by hand and compress the positioning spring 13 to separate the limiting block 15 from the slot of the support frame 2. Then move the entire connecting plate 3 upward to disengage it from the support frame 2. After that, release the insert 12 and use the reverse elastic force of the positioning spring 13 to reset the insert 12 and the limiting block 15. When the loading platform 6 and feeding rod 7 need to be quickly installed, simply align the insert 12 and the slot of the support frame 2 and insert them. Let the top of the support frame 2 press against the inclined surface of the limiting block 15, so that the limiting block 15 is retracted into the insert 12 and the positioning spring 13 is compressed. When the limiting block 15 and the slot of the support frame 2 coincide, use the reverse elastic force of the positioning spring 13 to reset the moving plate 14 and the limiting block 15, so that the limiting block 15 is inserted into the slot of the support frame 2, thus completing the entire installation process.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
