Technical Field
[0001] The utility model belongs to an important structure of a roll paper packaging machine, in particular to a roll paper central driving 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 the outer periphery of the roll of paper with several layers of kraft paper. Many existing ones adopt a semi-automatic method, where the roll of paper is placed on the machine for rotation, and the kraft paper is manually pulled for wrapping. For example, application number 201821613886.7 discloses a kraft paper packaging device for a semi-automatic finished roll of paper packaging line. This type of roll of paper packaging machine pushes the outer periphery of the roll of paper to rotate during packaging. When external force acts on the roll of paper, it is easy to cause the roll of paper to be damaged; at the same time, because the roll of paper is large, a larger force is required, which may cause deformation of the inside of the roll of paper, etc., affecting the quality of the roll of paper.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0016] Reference Figure 1 to Figure 3 The central driving mechanism of the roll paper of the roll paper packaging machine includes a first support frame 1, a second support frame 2 and a rotating device 3. The first support frame 1 and the second support frame 2 are arranged correspondingly. The rotating device 3 includes an active component 31 and a driven component 32. The active component 31 is arranged on the first support frame 1, and the driven component 32 is arranged on the second support frame 2. The active component 31 and the driven component 32 are arranged opposite to each other.
[0017] When the central driving mechanism of the paper roll of the paper roll packaging machine is in use, the two ends of the paper roll are respectively placed on the first support frame 1 and the second support frame 2, and the paper roll is supported by the active component 31 and the driven component 32, and the paper roll is driven to rotate, so that the external kraft paper can be wound around the paper roll to package the paper roll.
[0018] The active component 31 includes a driving motor 311 and a first rotating shaft 312 . The driving motor 311 is disposed on the first support frame 1 . The first rotating shaft 312 is connected to the output shaft of the driving motor 311 . The driven component 32 includes a second rotating shaft 321 . The first rotating shaft 312 and the second rotating shaft 321 are disposed opposite to each other.
[0019] Specifically, the first rotating shaft 312 and the second rotating shaft 321 are respectively inserted into the central tube at the center of the paper roll, and the first rotating shaft 312 is driven to rotate by the driving motor 311, thereby driving the paper roll to rotate, so that the kraft paper is wrapped around the outer periphery of the paper roll for packaging. By providing the second rotating shaft 321, the paper roll can rotate more smoothly.
[0020] The roll paper center driving mechanism of the roll paper packaging machine of the present utility model also includes a first moving frame 6, a first slide rail 7, a first stepping motor 8 and a first screw rod 9. The first slide rail 7 is installed on the first support frame. The bottom of the first moving frame 6 cooperates with the first slide rail 7. The first stepping motor 8 is installed on the first moving frame 6. One end of the first screw rod 9 is connected to the first stepping motor 8, and the other end passes through the first moving frame 6 and is connected to the first support frame. The driving motor 311 is fixed on the first moving frame 6. Among them, the first stepping motor 8 is a screw stepping motor. Since the other end of the first screw rod 9 is sleeved on the first mounting frame 5, when the first stepping motor 8 drives the first screw rod 9 to rotate, the first stepping motor 8 and the first moving frame 6 can move relative to the first screw rod 9, so that the first moving frame 6 can move along the first slide rail 7.
[0021] The roll paper center driving mechanism of the roll paper packaging machine also includes a second moving frame 20, a second slide rail 30, a second stepping motor 5 and a second screw 4. The second slide rail 30 is installed on the second support frame. The bottom of the second moving frame 20 cooperates with the second slide rail 30. The second stepping motor 5 is installed on the second moving frame 20. One end of the second screw 4 is connected to the second stepping motor 5, and the other end passes through the second moving frame 20 and is connected to the second support frame. The second rotating shaft 321 is arranged on the second moving frame 20. Among them, the second stepping motor 5 is a screw stepping motor. Similarly, when the second stepping motor 5 is working, the second stepping motor 5 and the second moving frame 20 can move along the second slide rail 30.
[0022] When the paper roll is transported between the first support frame 1 and the second support frame 2, the first rotating shaft 312 needs to be inserted into the central tube of the paper roll from one side. Specifically, the first stepper motor 8 can drive the first movable frame 6 to move, and the driving motor 311 on the first movable frame 6 can move synchronously, thereby driving the first rotating shaft 312 to move toward one side of the paper roll, thereby realizing the insertion of the first rotating shaft 312. Similarly, when the second rotating shaft 321 needs to be inserted into the central tube of the paper roll from the other side, the second stepper motor 5 drives the second movable frame 20 to move, thereby driving the second rotating shaft 321 to move toward the side of the paper roll, thereby realizing the insertion of the second rotating shaft 321. Conversely, when the paper roll is packaged, the first stepper motor and the second stepper motor rotate in opposite directions, thereby pulling the first rotating shaft and the second rotating shaft out in opposite directions.
[0023] The front end surface of the first support frame 1 and the front end surface of the second support frame 2 are both provided with through holes 10, and the first rotating shaft 312 and the second rotating shaft 321 can extend through the through holes. Therefore, when the first rotating shaft 312 and the second rotating shaft 321 extend, they extend through the through holes 10 to drive the roll paper to rotate; after the roll paper is packaged, the first rotating shaft 312 and the second rotating shaft 321 are retracted to the inner side of the through hole 10 to facilitate the movement of the roll paper.
[0024] A ball bearing 40 is disposed at the joint between the second rotating shaft 321 and the second moving frame 20 .
[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.
[0026] In actual use, the first rotating shaft 312 and the second rotating shaft 321 are both inflatable shafts. Therefore, when the two rotating shafts are inserted into the central paper tube from both sides, they are ventilated and expanded, and their diameters increase, so that they are closely matched with the central paper tube, thereby driving the paper roll to rotate synchronously; and after packaging, they can be deflated to reduce the diameter, making it easier to pull out the shafts.
