Technical Field

[0001] The utility model belongs to an important structure of a roll paper packaging machine, in particular to an automatic cover plate pressing mechanism of the roll paper packaging machine. Background Art

[0002] For rolls of paper with high requirements for printing, decoration or other purposes, the weight of the entire roll of paper is relatively large. In order to prevent the surface of the roll of paper from being worn, it is necessary to wrap a layer of plastic film around the periphery of the roll of paper, and then wrap kraft paper around the periphery of the plastic film. For example, application No. 201821613886.7 discloses a kraft paper packaging device for a semi-automatic finished roll of paper packaging line. However, after the kraft paper is wrapped around the periphery of the roll of paper, it is necessary to cover the two ends of the roll of paper with a cover plate. When pressing the cover plate, the operator needs to align the cover plate with the end surface of the roll of paper, cover it on both ends of the roll of paper, and then use tape to tighten the cover plate. The whole process is relatively cumbersome and consumes a lot of manpower. Utility Model Content

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Reference Figure 1 to Figure 4. The automatic cover plate mechanism of the roll paper packaging machine includes a cover plate device 1. There are two cover plate devices 1 and they are arranged opposite to each other. The cover plate device 1 includes a flip frame 11, a flip motor 12 and a material picking assembly 13. The flip frame 11 is connected to the output shaft of the flip motor 12, and the material picking assembly 13 is arranged on the flip frame 11. Specifically, the flip motor 12 can drive the flip frame 11 to flip, so that the flip frame 11 can be rotated to a horizontal state and a vertical state, so that the material picking assembly 13 can be in a horizontal and vertical state. When the material picking assembly 13 needs to pick up materials, the flip motor 12 drives the flip frame 11 to rotate to a horizontal state, so that the material picking assembly 13 picks up materials horizontally; after the material picking is completed, the flip motor 12 drives the flip frame 11 to rotate to a vertical state, so that the cover plate on the material picking assembly 13 rotates to a vertical state together, so that it is convenient to cover the corresponding end surface of the roll paper.

[0017] The material picking assembly 13 includes a material picking tray 131 , a suction cup 132 and a first suction cup cylinder 133 . The suction cup 132 is disposed on the material picking tray 131 . The cylinder body of the first suction cup cylinder 133 is fixed on the turning frame 11 . The material picking tray 131 is connected to the piston rod of the first suction cup cylinder 133 .

[0018] When the flip frame 11 rotates to a horizontal state, the cut cover plate is located directly below the material pickup tray 131. At this time, the piston rod of the first suction cup cylinder 133 extends, so that the suction cup 132 and the material pickup tray 131 are downward, and the suction cup 132 sucks the cover plate tightly. Subsequently, the flip motor 12 drives the flip frame 11 to rotate to a vertical state, and the cover plate faces the corresponding end face of the roll paper. At this time, the first suction cup cylinder 133 pushes the material pickup tray 131 to move toward the end face of the roll paper, so that the cover plate is tightly attached to the end face of the roll paper; after the cover plate is covered, the first suction cup cylinder 133 moves in the opposite direction, and the suction cup 132 and the material pickup tray 131 are separated from the cover plate.

[0019] In actual use, the side of the cover plate opposite to the paper roll can be pre-sprayed with glue, so that when the material picking tray 131 pushes the cover plate to press against the end surface of the paper roll, the cover plate is tightly fixed to the end surface of the paper roll by the glue, completing the fixation of the cover plate.

[0020] The automatic cover plate mechanism of the roll paper packaging machine of the utility model also includes a material moving device 2, which includes a material moving motor 21, a material moving frame 22 and a moving track 23. The material moving frame 22 is arranged on the moving track 23, and the material moving motor 21 is connected to the material moving frame 22. The material moving frame 22 is arranged corresponding to the material taking tray 131, that is, the material moving frame 22 can be moved to the bottom of the material taking tray. Among them, a slider is fixed on the material moving frame 22, and the material moving frame 22 cooperates with the moving track 23 through the slider. The moving track 23 can guide the material moving frame 22 and help improve the stability of the movement of the material moving frame 22.

[0021] The material moving device 2 further includes a second suction cup cylinder 24 and a suction cup frame 25 . The second suction cup cylinder 24 is fixed on the material moving frame 22 , and the suction cup frame 25 is connected to the piston rod of the second suction cup cylinder 24 .

[0022] The automatic cover plate pressing mechanism of the roll paper packaging machine also includes a rotary motor 3 and a connecting rod 4. The rotary motor 3 is installed on the material moving rack 22. The connecting rod 4 is connected to the output shaft of the rotary motor 3. The second suction cup cylinder 24 is arranged on the connecting rod 4.

[0023] The material moving device 2 further includes a transmission belt 26 and a pulley 27. There are two pulleys 27, one of which is connected to the output shaft of the material moving motor 21. The transmission belt 26 is sleeved on the two pulleys 27. The material moving frame 22 is clamped and fixed on the transmission belt 26. The transmission direction of the transmission belt 26 is consistent with the length direction of the moving track 23. The transmission belt 26 is located below the flip frame 11. Therefore, when the moving motor 21 is working, the transmission belt 26 is driven by the pulley 27 to transmit, and the transmission belt 26 drives the material moving frame 22 to move together, so that the material moving frame 22 moves along the moving track 23.

[0024] When the material moving device 2 is taking materials, the material moving motor 21 drives the suction cup frame 25 on the material moving frame 22 to move to the cut cover plate sprayed with glue. At this time, the side of the cover plate sprayed with glue faces up. When the suction cup frame 25 moves to the top of the cover plate, the piston rod of the second suction cup cylinder 24 extends downward, so that the suction cup frame 25 sucks the cover plate downward; then, the rotating motor 3 drives the connecting rod 4 to rotate 180°, so that the second suction cup cylinder 24 and the suction cup frame 25 on the connecting rod 4 are rotated 180°. At this time, the cover plate is turned up and down with the suction cup frame 25, so that the side sprayed with glue faces down. At this time, the material moving motor 21 drives the entire material moving frame 22 to move to one side of the cover plate pressing device 1. When the cover plate moves into place, the flipping motor 12 drives the flipping frame 11 to rotate to a horizontal state, and the suction cup 132 sucks the cover plate on the suction cup frame 25 tightly, so that the cover plate is transferred to the material taking tray 131 to complete the material taking. At this time, the side of the cover plate with glue is kept downward, and then the flip motor 12 drives the flip frame 11 to rotate to a vertical state, so that the cover plate rotates to a vertical state along with the flip frame 11, so that the side of the cover plate sprayed with glue faces the end face of the roll paper. Then, the piston rod of the first suction cup cylinder 133 extends, pushing the material picking tray 131 to move toward the end face of the roll paper, so that the cover plate is closely attached to the end face of the roll paper, completing the covering of the cover plate on the end face of the roll paper. As a result, the entire process does not require manual operation, saving labor, realizing the automatic covering of the cover plate, and greatly reducing labor costs.

[0025] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
