[0003] The conveyor belt platform at the feeding end of the existing film packaging machine can horizontally translate back and forth on the frame of the film packaging machine to adjust the actual position of the film feeding port for product packaging, so as to facilitate the docking of the next sealing process. However, the film supply assembly of such a film packaging machine is fixed on the frame of the film packaging machine, so it cannot move synchronously with the conveyor belt platform.

[0004] When switching the film packaging for different products, it is necessary to re-translate the conveyor belt platform, which will change the horizontal position of the conveyor belt platform, or change the distance between the film feeding port of the conveyor belt platform and the discharging end of the film supply assembly. As a result, the length of the film extending into the film feeding port after translation is too small or too large, that is, abnormal phenomena such as the film being too tight or too loose will occur. Therefore, the operator needs to adjust the machine of the film supply assembly additionally, so the time required for the entire cutting is too long, seriously affecting the production efficiency. Summary of the Utility Model

[0005] Therefore, to solve the above problems, the utility model provides a feeding device of a film packaging machine and the film packaging machine, which can ensure that the film supply assembly and the film packaging mechanism are integrally connected to achieve synchronous movement, thereby avoiding abnormal phenomena such as the film being too tight or too loose during cutting, saving the time required for cutting, and thus improving the production efficiency.

[0021] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0022] Embodiment 1

[0023] Reference Figure 1 and Figure 2 As shown, the first embodiment provides a feeding device of a film packaging machine (hereinafter referred to as the feeding device), which is used to complete operations such as film supply and preliminary film wrapping of the product to be packaged in the feeding process of the film packaging machine.

[0024] The feeding device includes a film wrapping mechanism 1 for wrapping the product to be packaged and a film supply assembly 2 for providing a film. The film wrapping mechanism 1 is arranged to be translatably movable, and the film supply assembly 2 is assembled to the film wrapping mechanism 1 through a connecting piece so that the film supply assembly 2 and the film wrapping mechanism 1 form an integral connection arrangement.

[0025] In this embodiment, the specific film is a folded double-layer film, and the film wrapping mechanism 1 includes a conveyor belt 13 for carrying the products to be packaged, a pushing assembly 12 for driving the products to be packaged to the film wrapping inlet 11, and a film supporting assembly 14 for vertically stretching the film at the film wrapping inlet 11, wherein the film wrapping inlet 11 is the initial film wrapping feeding position formed after the telescopic end of the pushing assembly 12 is fully extended.

[0026] The film supply assembly 2 is arranged on the side of the film support assembly 14 away from the material pushing assembly 12, and is arranged in parallel and close to each other, so that the layout of the entire feeding device is more compact and the occupied volume is reduced accordingly.

[0027] like Figure 2 The film supporting assembly 14 shown includes an upper film supporting member 141 and a lower film supporting member 142 which are arranged in an upper and lower manner, and a conveyor belt 13 is arranged between the upper film supporting member 141 and the lower film supporting member 142 .

[0028] The film wrapping mechanism 1 is equipped with a frame 3 of a film packaging machine. The film wrapping mechanism 1 can be assembled on the frame 3 in a translational manner. The film wrapping mechanism 1 and the film supply assembly 2 together constitute the conveyor belt platform of this embodiment to realize the translation of the conveyor belt platform on the frame 3, and adjust the actual operating position of the film wrapping feed port 11 in the frame 3 perpendicular to the conveying direction of the conveyor belt 13 by translating the conveyor belt platform as a whole.

[0029] likeFigure 2 The film feeding assembly 2 shown includes a guiding roller 21, a supporting roller 22, a fixing roller 24 for fixing the film core, and a tension roller unit 23 for adjusting the film tension. The tension roller unit 23 applies pressure to the unrolled film to make the film form a tightened setting. The tension roller unit 23 includes a matching driving roller and a squeezing roller, and the film is clamped between the squeezing roller and the driving roller to ensure that the film tension of the film feeding assembly 2 extending into the film feeding inlet 11 of the film wrapping mechanism 1 is within the production specification range and at the same time ensure the continuous supply of the film.

[0030] By integrally connecting the film feeding assembly 2 and the film wrapping mechanism 1, it is ensured that the film feeding assembly 2 and the film wrapping mechanism 1 can move synchronously, so as to ensure that the length of the film of the film feeding assembly 2 extending into the film wrapping mechanism 1 always remains unchanged, thereby avoiding abnormal phenomena such as the film being too tight or too loose during tangency. Compared with the prior art, the feeding device of this embodiment does not need to adjust the machine for the film feeding assembly 2 anymore, so as to save the time required for tangency and thus improve the production efficiency.

[0031] In another preferred embodiment, a lead screw-nut pair 4 is provided between the frame 3 and the film wrapping mechanism 1. The film wrapping mechanism 1 is slidably assembled on the frame 3, and through the cooperation of the lead screw-nut pair 4, the film wrapping mechanism 1 is formed to be able to be translated at a fixed point. By rotating the lead screw-nut pair 4, the lateral displacement of the film wrapping mechanism 1 in the frame 3 is accurately controlled, and thus the actual working position of the film feeding inlet 11 is adjusted.

[0032] In another preferred embodiment, the upper film supporting member 141 is assembled on the upper side of the conveyor belt 13 in a liftable manner, and the lower film supporting member 142 is fixed on the lower side of the conveyor belt 13 to adjust the distance between the upper film supporting member 141 and the conveyor belt 13, so that it can adapt to the heights of different articles to be packaged after tangency.
