The embodiment aims at providing a packaging bag production line, and accurately speaking, provides a feeding device of the packaging bag production line, and further realizes the feeding or the feeding of plastic films.

Structurally, with reference to fig. 1 and 2, the feeder device has two parallel support plates 100. The two support plates 100 are vertically disposed, and at the same time, the two support plates 100 support both ends of one unwinding shaft.

Perfectly, a supporting plate 100 is provided with a motor, a transmission shaft and a transmission gear, thereby driving the unreeling shaft to rotate, so that the plastic film is continuously unreeled, and the requirement of packaging bag production is met.

Structurally, the top surface of the support plate 100 is provided with a first notch 110, and the first notch 110 is located at the intersection of the top edge and the side edge of the support plate 100, so that the first notch 110 is different from a conventional groove having two opposite side walls and a bottom wall, and the first notch 110 of this embodiment has one side wall and one bottom wall.

Obviously, the first notch 110 does not allow the unwinding shaft to be completely positioned and limited, and for this reason, the present embodiment is provided with the rotating plate 120.

The top surface of the rotating plate 120 is a first concave portion 130. referring to fig. 1, the first concave portion 130 and the first notch 110 cooperate to form a groove for accommodating the reel.

Thus, the first recess 130 cooperates with the first notch 110 to prevent the unwinding shaft from rolling down to the ground.

In order to ensure the continuous transmission between the motor and the unwinding shaft, the present embodiment further includes a shift lever 170 and a second cylinder 180 for driving the shift lever 170 to rotate, and the shift lever 170 abuts and limits the unwinding shaft against the side wall of the first notch 110.

That is, the operation of the second cylinder 180 causes the lever 170 to shift the unreeling shaft toward the first notch 110, thereby positioning the unreeling shaft and reducing the labor intensity of transferring the unreeling shaft from the first recess 130 to the first notch 110.

When the plastic film on the unreeling shaft is consumed, the whole weight of the unreeling shaft is reduced, then, the limit of the deflector rod 170 is relieved, the unreeling shaft can be easily pulled back to the first concave part 130 by hands, and the unreeling shaft is convenient to replace.

Reasonably, the second cylinder 180 and the shift lever 170 are installed on the support plate 100, which facilitates installation and reduces cost.

In some preferred embodiments, the toggle bar 170 may be provided with an inner circular surface 210 that abuts the payout roller.

Therefore, the unreeling shaft is limited, and the rotation of the unreeling shaft is not influenced.

In some preferred embodiments, it is possible to provide the support plate 100 with a first lever 190, the first lever 190 being provided with a rotation shaft 200 connected to the shift lever 170, the rotation shaft 200 forming a rotation center of the shift lever 170.

Thus, the toggle bar 170 toggles the unwind shaft by a rotational pattern instead of the usual linear pushing or pulling.

In some preferred embodiments, in order to prevent the fast-rotating unwinding shaft from being released from the groove, the first rod 190 and the bottom surface of the first notch 110 may form a recess for accommodating the unwinding shaft.

The first bar 190 is used to form a concave position, so as to avoid slotting on the side wall of the first notch 110, reduce the processing amount, facilitate replacement and maintenance when damaged, and avoid replacing the whole supporting plate 100.

In some preferred embodiments, to simplify installation, the support plate 100 may be provided with a horizontal slot 220 that receives the first rod 190.

Therefore, the first rod 190 can be fixed by using a small number of screws, and the structure is simple and convenient to install.

In order to realize automatic feeding, the first air cylinder 140 is further provided in this embodiment, and the first air cylinder 140 drives the rotating plate 120 to rotate up and down.

Preferably, the first cylinders 140 are disposed between the two support plates 100, and the number of the first cylinders is two, so that the rotation plate 120 can be driven to rotate, thereby lifting the unwinding shaft on which the packaging material is wound.

In some preferred embodiments, the first recess 130 may be hook-shaped, so that the unreeling shaft is difficult to escape from the first recess 130 during rotation.

In some preferred embodiments, the first recess 130 may have a first recess 150, an extension surface 160 connecting the first recess 150, and the extension surface 160 and the bottom surface of the first notch 110 form a groove bottom of the groove.

Therefore, when the rotating plate 120 is rotated to a proper position, the extension surface 160 is as high as the bottom surface of the first notch 110, so that the unreeling shaft can be smoothly rolled toward the first notch 110, and the unreeling shaft does not fall from the first recess 130 to the first notch 110.

To keep the feeding apparatus compact, the rotating plate 120 may be disposed obliquely below the support plate 100.

Thus, the space between the two support plates 100 is less occupied, and the distance between the two support plates 100 is prevented from being increased.

In some preferred embodiments, the rotating plate 120 may be provided as thick as the support plate 100.

Because can set up spacing concave ring or spacing annular on the unreeling shaft, therefore, spacing annular card is on rotor plate 120 to, can unimpededly roll to backup pad 100, and do not produce axial skew, need not adjust the other positions of wrapping bag production line, make the high-efficient continuous work of wrapping bag production line.

In conclusion, the rotating plate 120 and the first cylinder 140 are arranged in the embodiment, so that when the first cylinder 140 drives the rotating plate 120 to rotate, the rotating plate 120 drives the unreeling shaft to ascend and descend, and then the unreeling shaft is transferred to the first notch 110, and the mode that the unreeling shaft is directly put into the groove in the prior art is replaced, therefore, the requirement can be met by arranging a small groove, namely, the groove is reduced, the occupied space is reduced, and the feeding device is compact in structure.

Meanwhile, in the embodiment, the first notch 110 and the first concave portion 130 are used to form a groove in a matching manner, instead of the conventional manner that the groove is completely formed in the support plate 100, on one hand, when the rotating plate 120 is far away from the support plate 100, the space around the first concave portion 130 is sufficient, and the unreeling shaft can conveniently enter and exit the first concave portion 130, and on the other hand, the first cylinder 140 drives the rotating plate 120 to rotate, so that the unreeling shaft can move towards the first notch 110, and specific tools such as a forklift are not needed, thereby reducing the difficulty in loading or feeding.

Moreover, in this embodiment, the first notch 110 and the first concave portion 130 cooperate to form a groove, and the unreeling shaft can stably roll or move from the first concave portion 130 to the first notch 110, so as to avoid the unreeling shaft from falling, prevent the gravity of the unreeling shaft from impacting the support plate 100, protect the unreeling shaft and the support plate 100, and ensure that the feeding device is durable and highly reliable.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
