Description

Technical Field

[0001] This utility model belongs to tobacco machinery, specifically relating to a cigarette machine paper alignment device and a cigarette machine. Background Technology

[0002] Tipping paper, as an important auxiliary material in cigarette paper production, may shift its position during long-distance transportation. Currently, it is mainly adjusted by limiting devices. When the displacement of tipping paper is small, the limiting device can be adjusted by the operator. However, when the displacement is large, it may have the opposite effect, causing the tipping paper to fold back. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a cigarette machine tipping paper correction device and a cigarette machine, which can adjust the tipping paper position to ensure that the tipping paper position can be adjusted smoothly and to guarantee product quality.

[0004] The technical solution provided by this utility model is as follows:

[0005] This utility model provides a paper-loading correction device for a cigarette machine, including a base plate, a correction mechanism, and a drive assembly. Support arms and a lifting arm are respectively provided on both sides of the base plate. The correction mechanism includes a fixed frame and a transmission connection part. An infeed roller and an outfeed roller are pivotally connected to both ends of the fixed frame. A rotating shaft located below the middle of the infeed roller is provided at the front end of the support arm. The transmission connection part includes a first connection part hinged to the rotating shaft and a second connection part parallel to and fixed to the lower long side of the fixed frame. The fixed frame on the outfeed roller side is provided with a sliding assembly that rolls with the lifting arm. The base plate is provided with a crank mechanism connected to the fixed frame via a connecting rod. The crank mechanism is connected to the drive assembly. Under the action of the drive assembly, the crank mechanism, in conjunction with the connecting rod, causes the fixed frame on the infeed roller side to swing around the rotating shaft, while the sliding assembly on the outfeed roller side rolls along the lifting arm to achieve bidirectional correction.

[0006] Furthermore, the fixing frame includes two long horizontal bars and two short vertical bars connected between the two long horizontal bars. A mounting bracket for mounting a sliding component is provided on the short vertical bar near the paper output roller. An arc-shaped groove is provided on the boom. The symmetrical center line of the arc-shaped groove coincides with the horizontal axis of the rotation shaft. The mounting bracket has two symmetrically arranged in the arc-shaped groove and located away from the two ends of the arc-shaped groove. The sliding component is a pulley, and the pulley is in contact with the arc-shaped edge of the arc-shaped groove on the side near the rotation shaft.

[0007] Furthermore, an intermediate connecting portion is provided between the first connecting portion and the second connecting portion to avoid the feeding paper from wrapping around the paper roller, and the intermediate connecting portion is inclined.

[0008] Furthermore, the front end of the support arm is provided with a mounting base, and a bearing is provided in the gap of the mounting base. The inner ring of the bearing is hinged to the first connecting part of the transmission connection part.

[0009] Furthermore, the crank mechanism includes a crank disc, which is connected to one end of a connecting rod via a crank spindle, and the other end of the connecting rod is connected via a fixed frame spindle, which is connected to the side of the fixed frame near the base plate.

[0010] Furthermore, an offset detection sensor is installed behind the paper output roller, and the offset detection sensor is electrically connected to the cigarette machine PLC.

[0011] Furthermore, the offset detection sensor is a photoelectric sensor or an ultrasonic sensor.

[0012] Furthermore, the base plate is positioned close to the bottom of the glue cylinder for attaching the cigarette machine.

[0013] Furthermore, the drive component is a servo motor or a manual lead screw.

[0014] This utility model also provides a cigarette machine, including the cigarette machine tipping paper correction device described above.

[0015] Beneficial effects

[0016] The paper feeding correction device of this utility model drives the fixed frame on the paper feed roller side to swing around the rotation axis at the front end of the support arm through a crank mechanism connected to the drive component. At the same time, the sliding component on the paper output roller side rolls along the boom to perform bidirectional dynamic correction. The rotating shaft is hinged to the first connecting part to enhance the stability of the paper feed roller swing by acting as a fulcrum. Combined with the rigid second connecting part of the parallel fixed frame to constrain the motion trajectory, the high precision of the correction action is ensured. The rolling cooperation structure between the boom and the sliding component reduces running resistance and wear.

[0017] The tipping paper correction device of this utility model changes the original tipping paper conveying path, eliminates the original limit block, and optimizes the overall structure of the correction device, making the structure more compact, reducing the space occupied, and making it suitable for small installation spaces, meeting the needs of existing cigarette machine models.

[0018] The splicing paper correction device of this utility model can adjust the splicing paper position, ensuring that the splicing paper position can be adjusted smoothly. Through multi-structure linkage optimization, it significantly improves the splicing paper positioning accuracy and equipment operation reliability, and ensures product quality.
