[0043] The servo motor and the associated circuit and the like involved in the present application are all existing technologies, and those skilled in the art can realize them without further description. The content protected by the present application does not involve the improvement of software, circuit and method.

[0044] Working principle: in actual application, when the plastic packaging machine needs to be automatically fed, first, the feeding groove 1 is aligned with the feeding port of the plastic packaging machine and the power is turned on, then the operator directly places the plastic packaging bags to be fed in the feeding groove 2, the pushing plate 3 is close to one side of the feeding groove 1, and then the motor one 52 is started, the output shaft drives the screw rod 51 to rotate, since the mounting plate 5 is threadedly connected with the screw rod 51 and the mounting plate 5 is slidably installed in the two sliding grooves 111, the mounting plate 5 will move back and forth along the sliding groove 111 under the drive of the screw rod 51. During this process, the position of the mounting plate 5 is adjusted so that the driving gear 61 on the motor two 6 can accurately align with the corresponding rigid tooth plate 43 of the feeding groove 2 to be fed and mesh with it.

[0045] Once the drive gear 61 is engaged with the rigid toothed plate 43, the motor two 6 is started next, the output shaft of the motor two 6 drives the drive gear 61 to rotate, since the rigid toothed plate 43 is engaged with the drive gear 61, therefore the rigid toothed plate 43 will move transversely along the strip-shaped plate 11 under the drive of the drive gear 61, at the same time the rigid toothed plate 43 drives the pushing plate 3 to slide in the feeding groove 2 through the connecting block 42, so as to push the plastic packaging bag stored in the feeding groove 2 to the guide port 21, and finally push into the feeding groove 1 and realize the feeding operation.

[0046] In order to ensure the stability and continuity of the feeding process, sensors can also be arranged in the system to monitor the number of plastic packaging bags in the feeding groove 2 and the feeding groove 1, when the number of plastic packaging bags in the feeding groove 2 is reduced to a certain extent, the system will automatically start the feeding mechanism to supplement new plastic packaging bags into the feeding groove 2; at the same time, when the number of plastic packaging bags in the feeding groove 1 is too much, the system will automatically pause the feeding operation to avoid the accumulation of plastic packaging bags leading to blockage or damage.

[0047] In addition, in order to further improve the degree of automation and intelligent level of the system, the automatic feeding device in the embodiment can be integrated with the control system of the plastic packaging machine, various parameters and logical relationships are set through programming, so that the automatic feeding device can automatically adjust the feeding speed and quantity according to the production demand of the plastic packaging machine, so as to realize the overall automation and intelligent management of the production process.

[0048] The automatic feeding device of the plastic packaging machine provided by the utility model is described in detail above. The principles and implementation modes of the utility model are described in this paper, and the above examples are only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the utility model without departing from the principles of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claims.
