Description

Paper tray frame with centering device

Technical Field

The invention belongs to the field of cigarette production equipment, and particularly relates to a paper tray frame with a centering device.

Background

In the cigarette production enterprises, a large amount of bobbin base paper is required to be used, and when the bobbin base paper is used specifically, the bobbin base paper is generally placed on a feeding mechanism such as a paper tray frame, and the paper is discharged through the rotation of the paper tray frame.

Chinese utility model patent with publication number CN201087045Y discloses an aluminium foil paper roll plate holder device of cigarette packing machine, including the frame seat that is equipped with two sets of aluminium foil paper feeding mechanisms, feeding mechanism includes the back shaft, respectively the activity suit in the reel that back shaft, tip install rocking arm and rocking arm return spring to the paper guide roll, every set of feeding mechanism is still including driving reel pivoted actuating mechanism and power control system. The independent motor is adopted to provide power for the aluminum foil paper reel, and the control system controls the work of the driving motor, so that the synchronous paper feeding with the whole machine is realized.

In the above disclosed aluminum foil paper roll tray device of the cigarette packing machine, the reel is provided with the support shaft, and the paper core of the rolled paper is inserted into the support shaft to support the rolled paper. However, the supporting shaft is fixed to the paper feeding mechanism, and when the paper feeding mechanism is deviated from a subsequent device in actual use, that is, the conveying direction is deflected during paper conveying, the mechanism is inconvenient to adjust the position of the paper feeding mechanism, that is, the center deviation phenomenon is easily generated, and the normal use of the paper is affected.

Disclosure of Invention

The invention aims to provide a paper tray frame with a centering device, which can conveniently adjust the position of bobbin paper after the bobbin paper is placed on the paper tray frame, so as to realize centering operation.

The technical purpose of the invention is realized by the following technical scheme:

the paper tray frame with the centering device comprises a reel, wherein a supporting shaft is arranged on one side of the reel and is perpendicular to the reel, the supporting shaft is arranged in a hollow mode, a central shaft is arranged in the center of the supporting shaft along the axis direction of the supporting shaft, the central shaft is fixedly connected with the reel, the supporting shaft is sleeved outside the central shaft in a sliding mode, and a centering piece for driving the supporting shaft to slide along the central shaft is arranged at one end, far away from the reel, of the central shaft.

Furthermore, the centering piece comprises a handle in threaded connection with the end part of the central shaft, which is far away from the reel, and one end of the support shaft, which is close to the handle, is rotatably sleeved outside the handle.

Furthermore, a connecting rod mechanism and a driving part for driving the connecting rod mechanism to extend out of the side wall of the supporting shaft are arranged in the supporting shaft.

Furthermore, the lateral wall of back shaft is equipped with the connecting rod chamber along its axial, link mechanism is including the activity locate the tensioning arm of connecting rod intracavity, tensioning arm both ends respectively through the pendulum rod with connecting rod chamber lateral wall is articulated, the tensioning arm can follow the pendulum rod rotates, and stretches out the connecting rod chamber.

Furthermore, the driving part comprises a conical sleeve which is sleeved outside the central shaft in a sliding manner, an arc-shaped groove is formed in the outer wall of the conical sleeve along the axial direction of the conical sleeve, and a pushing wheel matched with the arc-shaped groove is arranged on the end face, close to the conical sleeve, of the tensioning arm.

Furthermore, an electromagnet is arranged outside one end of the central shaft, and the end part of the conical sleeve, which is opposite to the electromagnet, is arranged on a magnet which is mutually adsorbed or repelled with the electromagnet.

The invention has the beneficial effects that:

1. the back shaft slides and overlaps and establish outside the center pin, and its one end of keeping away from the reel rotates with the handle and is connected, handle and center pin threaded connection, like this, during the operation, overlaps the refill of bobbin paper outside the back shaft, later revolves the twist handle, and the relative center pin of handle is along its axial displacement, can drive the back shaft and remove, carries out the operation of centering.

2. The tensioning arm is movably arranged in the supporting shaft, so that when tensioning is needed, the tensioning arm is driven by the driving part to extend out of the supporting shaft so as to perform tensioning operation; when the tension is not needed, the drive of the drive mechanism to the tension arm is removed, so that the tension arm can be retracted into the support shaft under the action of gravity or other external force, and the bobbin paper sleeved outside the support shaft can be smoothly installed or replaced.

3. The tensioning arm is matched with the outer wall of the conical sleeve through the push wheel, so that the tensioning arm can be indirectly pushed to move relative to the supporting shaft only by driving the conical sleeve to move, and the tensioning arm can extend out of the supporting shaft to perform tensioning operation or can be retracted into the supporting shaft.

4. The end face of one end, far away from the reel, of the conical sleeve is fixedly connected with a magnet, and the periphery of one end, close to the magnet, of the central shaft is fixedly connected with an electromagnet. Therefore, when current is applied to the coil of the electromagnet in one direction, the electromagnet and the magnet repel each other, the conical sleeve is pushed to move towards the direction of the reel, and the tensioning arm is driven to extend outwards to perform tensioning operation; when current in the opposite direction is applied to the coil of the electromagnet, the electromagnet and the magnet are mutually adsorbed, the conical sleeve moves in the direction away from the reel, the tensioning arm loses support and retracts into the connecting rod cavity, and the bobbin paper can be taken down.
