[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Reference Figure 1 to Figure 3 The automatic cork feeding mechanism of the roll paper packaging machine comprises a material rack 1, a mounting rack 2 and a capping device 3. The capping device 3 comprises a motor 31, a push block 32, a movable rack 33 and a material receiving block 34. The material receiving block 34 is connected to the movable rack 33. The material receiving block 34 is arranged corresponding to the material outlet of the material rack 1. The motor 31 is arranged on the mounting rack 2. The movable rack 33 is connected to the motor 31. The motor 31 pushes the movable rack 33 to move. The push block 32 is connected to the movable rack 33. The push block 32 corresponds to the material receiving block 34.

[0019] When in use, many corks are placed in the material rack 1, and the channel in the material rack 1 is Y-shaped, so that only one cork can fall from the bottom. The discharge port in the material rack 1 falls onto the material receiving block 34, and then the motor 31 drives the moving rack 33 to move, and the moving rack 33 drives the push block and the material receiving block 34 to move to the center tube of the paper roll, and then the push block 32 pushes the cork into the center tube of the paper roll to complete the corking action. The whole process does not require manual operation, saving labor. Since corks need to be inserted at both ends of the paper roll, the cork automatic feeding mechanism of the paper roll packaging machine is installed at both ends of the paper roll, and the paper roll can be corked at both ends at the same time, which improves work efficiency.

[0020] The motor 31 is a screw stepper motor, and the screw 311 in the motor 31 can penetrate the motor 31 and be connected to the moving frame 33. The housing of the motor 31 is fixed on the mounting frame 2, and the screw is connected to the moving frame 33. The screw can penetrate the motor 31 and move forward and backward. This type of screw stepper motor is a prior art. When the motor 31 is working, the screw can move forward and backward relative to the housing of the motor, thereby driving the moving frame 33 to move, and can drive the material receiving block 34 to move to one side of the paper roll, or move in the opposite direction, to meet the corresponding use requirements.

[0021] The receiving block 34 is U-shaped and is provided with a U-shaped groove 341, which corresponds to the discharge port of the material rack 1, and the push block 32 is located in the U-shaped groove 341. By providing the U-shaped groove 341, the position of the wooden plug can be limited to prevent the wooden plug from shaking, and it is convenient for the wooden plug to align with the central tube of the paper roll.

[0022] The movable frame 33 is provided with a mounting hole 331 , and the material receiving block 34 matches with the mounting hole 331 , and the material receiving block 34 can pass through the mounting hole 331 .

[0023] The automatic cork feeding mechanism of the roll paper packaging machine also includes a connecting rod 4 and a spring 5. One end of the connecting rod 4 is fixed to the front end of the material receiving block 34, and the other end can penetrate the movable frame 33 and then extend out. The spring 5 is sleeved on the connecting rod 4, and one end of the spring 5 abuts against the material receiving block 34, and the other end abuts against the movable frame 33.

[0024] A connecting block 6 is fixed to the outer periphery of the front end of the material receiving block 34, one end of the connecting rod 4 is fixed to the material receiving block 34 through the connecting block 6, and one end of the spring 5 abuts against the connecting block 6. The connecting block 6 and the material receiving block 34 can be fixed by welding, or the front end of the material receiving block 34 can be folded outward to form.

[0025] The specific process of the automatic cork feeding mechanism of the paper roll packaging machine of the utility model when adding corks is as follows:

[0026] Start the motor 31, so that the motor's screw drives the moving frame 33 to move toward the side of the paper roll, and the moving frame 33 drives the material receiving block 34 and the push block 32 to move toward the side of the paper roll. As the motor 31 continues to work, when the front end face of the material receiving block 34 abuts against the end face of the paper roll, the material receiving block 34 cannot continue to move forward, and the motor 31 continues to push the moving frame 33 forward; under the action of the reverse force of the paper roll, the material receiving block 34 passes through the mounting hole 331 and moves in the opposite direction relative to the moving frame 33, that is, the moving frame 33 drives the push block 32 to continue to move forward, while the material receiving block 34 moves backward along the mounting hole 331, and the connecting rod 4 moves backward together with the material receiving block 34. Since the material receiving block 34 moves backward relative to the moving frame 33, and the moving frame 33 moves forward, the spring 5 is compressed.

[0027] As the moving frame 33 drives the push block 32 to continue to move forward, the push block 32 pushes the wooden plug in the U-shaped groove 341 forward into the central tube of the paper roll, completing the plugging of the wooden plug. Subsequently, the motor rotates in the reverse direction, causing the moving frame 33 to gradually move to the side away from the paper roll, and the material receiving block 34 can move forward relative to the moving frame 33 under the action of the spring rebound force, so that the relative position of the material receiving block 34 on the moving frame 33 is gradually restored. As the motor 31 continues to rotate in the reverse direction, the moving frame 33 drives the push block 32 and the material receiving block 34 to return to the starting position. At this time, the wooden plug on the material frame can fall into the U-shaped groove 341 again, facilitating the plugging of the wooden plug next time.

[0028] The material inlet 11 of the material rack 1 is V-shaped, so that the external corks can be easily added into the material rack 1 .

[0029] The automatic cork feeding mechanism of the roll paper packaging machine further comprises a protective cover 7 , which is fixed to the moving frame 33 by screws and is located above the motor 31 .

[0030] The automatic cork feeding mechanism of the roll paper packaging machine also includes guide rods 8, which are located on both sides of the motor 31. The guide rods 8 penetrate the mounting frame 2 and are connected to the moving frame 33. By providing the guide rods 8, the stability of the moving frame 33 when moving can be improved.

[0031] 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.
