DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1 As shown, a positioning device for a sealing film of a filling machine comprises an operating table 1 and a sealing assembly 12. A limiting groove 2 is provided on the surface of the operating table 1, and an electric push rod 3 is installed inside the limiting groove 2. The electric push rod 3 pushes the sealed filling container out of the limiting groove 2 to assist in unloading. A filling rack 4 is installed on the left side of the operating table 1, and a filling tube 5 is arranged on the side of the filling rack 4. The filling tube 5 performs quantitative filling on the filling container. A collecting box 6 is installed on the right side of the operating table 1, and a unloading tube 7 is installed at the lower end of the collecting box 6. The unloading tube 7 can be used for vertical placement of the filled container to facilitate the taking of the filled container. A unloading rack 8 is installed at the upper end of the side of the collecting box 6, and an electric push rod 2 9 is installed on the left side of the unloading rack 8. The electric push rod 2 9 drives the unloading plate 10 to pull the ejected filling container into the collecting box 6. The operation is simple, and the output end of the electric push rod 2 9 is connected to the unloading plate 10.

[0022] like Figure 2 As shown, a vertical plate 11 is installed on the rear side of the operating table 1, and a sealing component 12 for positioning and sealing the sealing film is arranged on the surface of the vertical plate 11, and the sealing component 12 includes a connecting plate 1201, a threaded sleeve rod 1202, a film pressing plate 1203 and a sealing pressing plate 1204. Threaded sleeve rods 1202 are arranged on both sides of the connecting plate 1201, and the outer sleeve shell of the threaded sleeve rod 1202 rotates to rotate its inner rod to control the lifting and lowering of the film pressing plate 1203, so that the lifting and lowering of the film pressing plate 1203 is stable, and a film pressing plate 1203 is installed at the end of the threaded sleeve rod 1202. The film pressing plate 1203 plays a role of pre-positioning, pressing and positioning the sealing film to avoid deviation or wrinkles of the film body during sealing, which affects the sealing effect. A sealing pressing plate 1204 is arranged on the inner side of the film pressing plate 1203. The sealing pressing plate 1204 accurately seals the container at the inner opening position of the film pressing plate 1203, thereby further improving the sealing accuracy.

[0023] like Figure 3 As shown, an auxiliary frame 13 is installed on the front side of the operating table 1, and a lower box hole 14 is opened on the surface of the auxiliary frame 13. A limit rod 15 is arranged on the outer side of the lower box hole 14, and eight limit rods 15 are arranged. The limit rods 15 play a stacking role for the empty boxes to be filled. A baffle 16 is arranged at the lower end of the lower box hole 14. The baffle 16 is used to block the empty boxes from being unloaded to prevent multiple empty boxes from falling at the same time, and an electric push rod 17 is installed at the end of the baffle 16.

[0024] In summary, the positioning device of the sealing film of the filling machine is first based on Figure 1-Figure 3The structure shown in the figure, when in use, the empty containers for filling are stacked in the limit rod 15, and the electric push rod 17 controls the lateral movement of the baffle 16, so that the empty boxes are quantitatively dropped from the lower box hole 14 to the limit slot 2, and the lower end of the operating table 1 is provided with a motor to rotate on the base, so that the empty boxes in the limit slot 2 are moved to the bottom of the filling tube 5 for quantitative filling, and the operating table 1 is rotated again to move it to the bottom of the sealing plate 1204, and the outer casing of the threaded sleeve 1202 is controlled to rotate by the motor, so that the inner rod rotates to control the lifting of the film pressing plate 1203, so that the lifting of the film pressing plate 1203 is stable, and the film pressing plate 1203 is stable. The sealing film plays a role of pre-positioning, pressing and positioning to avoid displacement or wrinkles of the film during sealing, which would affect the sealing effect. After the film is positioned, the sealing pressure plate 1204 accurately seals the container at the inner opening position of the film pressing plate 1203, further improving the sealing accuracy. The operating table 1 continues to rotate so that the sealed container is located on one side of the collecting box 6. The electric push rod 1 3 pushes the sealed filling container out of the limiting groove 2 to assist in unloading. The electric push rod 2 9 drives the unloading plate 10 to pull the ejected filling container into the collecting box 6. The operation is simple, and the unloading tube 7 can be used to vertically place the filled container, which is convenient for taking the filled container.
