DETAILED DESCRIPTION

[0021] Embodiment 1

[0022] like Figure 1-Figure 3 As shown, a paper cup punching machine proposed in this embodiment includes a frame 1, an upper transmission belt 3, a lower transmission belt 4, a mounting frame a6, a mounting frame b7, a winding roller 8, an unwinding roller 9, a limiting plate 15, a plurality of cutter seats 29 and a plurality of cutter assemblies.

[0023] The upper transmission belt 3 is arranged above the lower transmission belt 4, and a power mechanism for driving the upper transmission belt 3 and the lower transmission belt 4 to rotate synchronously is installed on the frame 1; the power mechanism includes a servo motor a2, a transmission shaft 25, four groups of transmission members a and two groups of transmission members b, the two groups of transmission members a are arranged on both sides of the upper end of the frame 1, and the two groups of transmission members a are arranged on both sides of the lower end of the frame 1, and the transmission member a includes a toothed belt a21 and four toothed belt pulleys a20, and the four toothed belt pulleys a20 are all rotatably installed on the frame 1, and the four toothed belt pulleys a20 are connected by the toothed belt a21. The upper transmission belt 3 is connected to the two toothed belts a21 at the upper end, and the lower transmission belt 4 is connected to the two toothed belts a21 at the lower end. Belt a21 is connected, and two groups of transmission parts b are respectively arranged on both sides of the frame 1. The transmission part b includes a toothed belt b23 and two toothed pulleys b22. The two toothed pulleys b22 are respectively connected to the rotating shafts of the toothed pulleys a20 on the upper and lower sides. The two toothed pulleys b22 are connected through the toothed belt b23. The rotating shafts of the two toothed pulleys a20 on the lower side are connected through a transmission shaft 25. The servo motor a2 is installed on the frame 1 and its output shaft is connected to the rotating shaft of the lower toothed pulley a20. Through the arrangement of the above-mentioned power mechanism, the synchronous driving of the upper transmission belt 3 and the lower transmission belt 4 can be realized to ensure that the upper transmission belt 3 and the lower transmission belt 4 can move at the same speed.

[0024] A plurality of cutter assemblies are evenly arranged along the path direction of the upper transmission belt 3 , and the cutter assemblies include a cutter mounting plate 5 and a cutter 28 mounted on the outer surface of the cutter mounting plate 5 .

[0025] The limit plate 15 is located on the inner side of the upper transmission belt 3, and one end of the limit plate 15 is an upwardly tilted structure; an elastic reset component is installed between the cutter assembly and the upper transmission belt 3, and the elastic reset component includes a hemispherical block 16, a spring 24, a fixed block 26 and a guide rod 27. The fixed block 26 is arranged on the upper transmission belt 3, and the guide rod 27 movably penetrates the fixed block 26. The two ends of the guide rod 27 are respectively connected to the hemispherical block 16 and the cutter mounting plate 5, and the spring 24 is sleeved and installed on the guide rod 27. When the hemispherical block 16 and the limit plate 15 are After the inclined surfaces contact, the hemispherical block 16 is forced to start moving downward, that is, driving the guide rod 27 and the cutter mounting plate 5 to move downward. When the hemispherical block 16 is separated from the limit plate 15, the hemispherical block 16 is driven to reset under the elastic force of the spring 24 to realize the automatic reset of the cutter mounting plate 5. When the elastic reset component contacts the inclined surface of the limit plate 15, the corresponding cutter component is forced to move downward. When the elastic reset component is separated from the limit plate 15, the cutter assembly is reset upward; multiple cutter seats 29 are evenly arranged along the path direction of the lower transmission belt 4.

[0026] The unwinding roller 9 is rotatably mounted on the mounting frame a6; the winding roller 8 is rotatably mounted on the mounting frame b7, and the mounting frame b7 is also equipped with a servo motor b10 for driving the winding roller 8 to rotate; the upper limit roller 11 and the lower limit roller 12 are rotatably mounted on the mounting frame a6 and the mounting frame b7, and a counter 13 is installed on the rotating shaft of the upper limit roller 11 on one side. The installed counter 13 can detect and record the number of rotations of the upper limit roller 11, and the circumference of the upper limit roller 11 is known. The counter 13 feeds back the detected data to the controller 14, so that the moving speed of the cardboard can be calculated. The controller 14 then controls the driving speed of the servo motor b10, thereby ensuring that the moving speed of the cardboard is relatively constant.

[0027] During operation, the servo motor b10 is started to drive the winding roller 8 to rotate, thereby realizing the movement of the cardboard. The upper transmission belt 3 and the lower transmission belt 4 are driven to rotate synchronously through the power mechanism set up. The upper transmission belt 3 drives multiple cutter mounting plates 5 to move, and the lower transmission belt 4 drives multiple cutter seats 29 to move. When the hemispherical block 16 contacts the inclined surface of the limit plate 15, it forces the guide rod 27 to move downward, thereby driving the cutter mounting plate 5 to move, and the cutter 28 cuts the moving cardboard, and the cut cardboard falls onto the cutter seat 29. When the cutter seat 29 rotates downward, the cut cardboard automatically falls off, realizing the function of automatic unloading. In summary, the technical solution can realize the continuous cutting of the moving cardboard without stopping, the working rhythm is compact and orderly, and the function of automatic unloading can be realized, and the working efficiency is high.

[0030] In this embodiment, when the Hall sensor moves close to the upper magnetic block 17, the control module controls the corresponding air pump to work, and the air pump works to adsorb the cut cardboard on the cutter seat 29. When the Hall sensor moves close to the lower magnetic block 17, the control module controls the air pump to shut down. At this time, the cardboard falls onto the stacking plate 19 under the action of gravity. The stacking plate 19 can be used to receive the fallen cardboard. The linear drive mechanism 18 can drive the stacking plate 19 to move upward intermittently, thereby realizing the stacking of multiple cardboards after cutting.
