Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, and particularly relates to an automatic feeding device for a paper cutter. Background Art

[0002] A paper cutter is a device used for cutting paper. A knife plate is slidably installed on the paper cutter. The paper to be cut is stacked below the knife plate. The knife plate is driven by a hydraulic cylinder to move towards the paper, so that the paper can be cut by the knife plate, which is suitable for cutting multiple stacked papers simultaneously.

[0003] The Chinese utility model patent with the publication number CN221561557U discloses a feeding device for a paper cutter, which relates to the technical field of conveying. It includes a paper cutter. A blanking groove is opened at the top of the paper cutter. A rotating rod is rotatably connected inside the blanking groove. A turning plate is fixedly sleeved on the outer wall of the rotating rod. One side of the paper cutter is fixedly connected with a blanking motor. The output end of the blanking motor penetrates through one side of the blanking groove and is fixedly connected with the rotating rod. Under the driving cooperation of two synchronous gears and a synchronous belt, the two paper supporting plates can move simultaneously, so as to facilitate the picking and placing of papers of different specifications. The feeding rack is convenient for transporting the paper to a suitable height under the rotation of the threaded rod. Under the meshing of the adjusting gear and the annular rack, the paper on the feeding rack can be rotated to the working surface of the paper cutter, so as to facilitate the cutting operation of the paper, without the need for manual multiple handling of the paper, thus reducing the manual labor intensity and improving the work efficiency.

[0004] Due to the limited height of the paper cutter's feeding port, if too many papers are stacked at the feeding port of the paper cutter at one time, the papers with a height exceeding the feeding port will not be able to enter the feeding port, resulting in some papers not being cut. Therefore, the feeding device for the paper cutter in the prior art has the technical problem of being unable to quantitatively convey papers. Summary of the Utility Model

Specific embodiments

[0034] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with embodiments. However, the scope of protection required by the present utility model is not limited to the following specific embodiments.

[0035] Refer to Figures 1-3 , an automatic feeding device of a paper cutter, including a fixed base 11, a vertical guide rod 12, a lifting tray 13, a horizontal guide rod 22 and a push plate 23.

[0036] The vertical guide rod 12 is fixedly installed on the fixed base 11. The lifting tray 13 is vertically slidably connected to the vertical guide rod 12. A vertical driving mechanism is provided between the lifting tray 13 and the fixed base 11. The vertical driving mechanism includes a bracket 15, a vertical lead screw 16 and a vertical driving member 17. The bracket 15 is fixedly installed on the fixed base 11. The vertical driving member 17 is installed on the bracket 15. The vertical lead screw 16 is fixedly connected to the output shaft of the vertical driving member 17. The vertical lead screw 16 is threadedly connected to the lifting tray 13. The vertical driving member 17 is a motor. The vertical driving member 17 drives the vertical lead screw 16 to rotate. During the rotation process, the vertical lead screw 16 drives the lifting tray 13 connected to it threadedly to move vertically, realizing the function of the vertical driving mechanism driving the lifting tray 13 to move vertically. The vertical guide rod 12 is fixedly connected with a support plate 14. The vertical lead screw 16 is rotatably connected to the support plate 14. The support plate 14 provides a supporting force for the vertical lead screw 16, playing a role in improving the structural stability of the mutual lead screw.

[0037] The support plate 14 is fixedly connected with a connecting frame 21. A transverse guide rod 22 is fixedly installed on the connecting frame 21. A push plate 23 is horizontally slidably connected to the transverse guide rod 22. A transverse driving mechanism is arranged between the push plate 23 and the connecting frame 21. The transverse driving mechanism includes a transverse lead screw 27 and a transverse driving member 28. The transverse driving member 28 is fixedly installed on the connecting frame 21. The transverse lead screw 27 is fixedly connected to the output end of the transverse driving member 28. The transverse lead screw 27 is threadedly connected to the push plate 23. The transverse driving member 28 is a motor. The transverse driving member 28 drives the transverse lead screw 27 to rotate. During the rotation process, the transverse lead screw 27 drives the push plate 23 threadedly connected thereto to move, realizing the function of the transverse driving mechanism driving the push plate 23 to move. The transverse lead screw 27 is rotatably connected to the connecting frame 21. The connecting frame 21 provides a supporting force for the transverse lead screw 27, playing a role in improving the structural stability of the transverse lead screw 27.

[0038] The connecting frame 21 is fixedly connected with a connecting rod 24. The connecting rod 24 is fixedly connected with a transverse guide rail 25. The push plate 23 is rotatably connected with a guide wheel 26 that cooperates with the transverse guide rail 25 and rolls along the extension direction of the transverse guide rail 25. The connecting rod 24, the transverse guide rail 25 and the guide wheel 26 are all provided in two. The two connecting rods 24, the transverse guide rails 25 and the guide wheels 26 correspond one by one. The two connecting rods 24, the transverse guide rails 25 and the guide wheels 26 are respectively arranged at both ends of the push plate 23. The two transverse guide rails 25 can respectively provide a supporting force for the push plate 23 at both ends of the push plate 23 through the guide wheels 26, ensuring that the push plate 23 remains stable during the movement process, playing a role in preventing the push plate 23 from tilting and jamming due to force.

[0039] The horizontal guide rail 25 is provided with a paper detection component. The paper detection component includes a first mounting rod 31, a second mounting rod 35, a first mounting seat 32, a second mounting seat 36, a laser 33 and a laser receiver 37. The first mounting rod 31 and the second mounting rod 35 are respectively fixedly mounted on two horizontal guide rails 25. The first mounting seat 32 and the second mounting seat 36 are respectively mounted on the first mounting rod 31 and the second mounting rod 35. The laser 33 and the laser receiver 37 are respectively mounted on the first mounting seat 32 and the second mounting seat 36, and the laser 33 and the laser receiver 37 are arranged oppositely. The laser 33 is used to emit laser light to the laser receiver 37, and the laser receiver 37 is used to receive the laser light. When the laser light is blocked, the laser receiver 37 cannot receive the laser light and issues a detection signal. The first mounting seat 32 and the second mounting seat 36 are respectively vertically slidably connected to the first mounting rod 31 and the second mounting rod 35. The first mounting seat 32 is threadedly connected with a first fixing member 34 that abuts against the first mounting rod 31, and the first fixing member 34 is a screw. Tighten the first fixing member 34 so that the first fixing member 34 abuts against the first mounting rod 31, and fix the first fixing member 34 and the first mounting seat 32 on the first mounting rod 31 through friction, so as to realize the function of fixing the first mounting seat 32 and the laser 33. The second mounting seat 36 is threadedly connected with a second fixing member 38 that abuts against the second mounting rod 35, and the second fixing member 38 is a screw. Tighten the second fixing member 38 so that the second fixing member 38 abuts against the second mounting rod 35, and fix the second fixing member 38 and the second mounting seat 36 on the second mounting rod 35 through friction, so as to realize the function of fixing the second mounting seat 36 and the laser receiver 37.

[0040] Specific working process: Place the stacked papers on the lifting tray 13. The vertical driving mechanism drives the lifting tray 13 to move upward. When the paper detection component detects the paper, the vertical driving mechanism stops operating. The horizontal driving mechanism drives the push plate 23 to move. The push plate 23 can contact the paper at a higher position but cannot contact the paper at a lower position. Thus, the paper at a higher position can be pushed onto the paper cutter by the push plate 23, and then the horizontal driving mechanism drives the push plate 23 back to its original position. The vertical driving mechanism drives the lifting tray 13 to move upward again. When the paper detection component detects the paper again, the vertical driving mechanism stops operating. The horizontal driving mechanism drives the push plate 23 to push the paper at a higher position onto the paper cutter, and operates in a cycle until the push plate 23 pushes all the papers on the lifting tray 13 onto the paper cutter.

[0041] This embodiment has the following advantages:

[0042] When the paper detection component detects the paper on the lifting tray 13, the tray stops driving the paper to move upward, and the higher-positioned paper is pushed onto the paper cutter by the push plate 23, so that positioning can be performed during the upward movement of the paper, and the thickness of the paper pushed by the push plate 23 during each paper pushing process is maintained within a certain limit, preventing the stacking height of the paper on the paper cutter from exceeding the paper inlet of the paper cutter, achieving the advantage of being able to quantitatively convey paper to the paper cutter.

[0043] When the paper is at a lower position, it cannot block the laser emitted by the laser device 33. The laser emitted by the laser device 33 irradiates on the laser receiver 37. At this time, the vertical driving mechanism is allowed to drive the lifting tray 13 to move upward. When the lifting tray 13 drives the paper to move upward and blocks the laser emitted by the laser device 33, the laser receiver 37 cannot receive the laser and issues a detection signal, so that it can be judged according to the detection signal that the paper has risen to the specified position. At this time, the vertical driving mechanism stops driving the lifting tray 13 to move. The function of limiting the lifting tray 13 and the paper through the paper detection component is realized.

[0044] The first mounting seat 32 and the second mounting seat 36 slide vertically on the first mounting rod 31 and the second mounting rod 35 respectively, driving the laser device 33 and the laser receiver 37 to move vertically respectively, so that the paper detection component detects the paper at different heights, realizing the function of positioning the lifting tray 13 and the paper at different heights, and can be applicable to paper cutters with different paper inlet heights.

[0045] According to the disclosure and teaching of the above specification, those skilled in the art to which the present invention pertains can also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
