Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-5 As shown, this utility model embodiment provides an automatic feeding device for an oxygen-barrier aluminum foil bag making machine, including a base plate 1. A feeding roller 3 is provided on the front side of the top of the base plate 1. A tension roller 4 is movably connected to the middle of the top of the base plate 1. A rotary motor 5 is fixedly installed on the left side of the top of the base plate 1. A first guide roller 6 is fixedly connected to the output end of the rotary motor 5. A second guide roller 7 is movably connected to the rear side of the top of the base plate 1. A lifting mechanism 2 is provided on the top of the base plate 1. The lifting mechanism 2 includes a drive motor 201 and screw blocks 203. The drive motor 201 is located on the left side of the base plate 1. The two screw blocks 203 are located on the left and right sides of the top of the base plate 1, and the outer sides of the two screw blocks 203 are fixedly installed. There are four connecting blocks 204. Each of the four connecting blocks 204 has a movable frame 205 fixedly installed on its outer side. Each of the four movable frames 205 has a connecting rod 206 movably connected to its inner side. Each of the four connecting rods 206 has a U-shaped frame 207 movably connected to its other end. Each of the four U-shaped frames 207 has a push plate 208 fixedly installed on its top. A drive motor 201 is fixedly installed on the left side of the base plate 1. The output end of the drive motor 201 is fixedly connected to a bidirectional threaded rod 202. Two screw blocks 203 are threadedly connected to the left and right sides of the surface of the bidirectional threaded rod 202. The thread directions on the left and right sides of the surface of the bidirectional threaded rod 202 are opposite, and the thread spacing on the left and right sides of the surface of the bidirectional threaded rod 202 is the same.

[0031] By setting up the lifting mechanism 2, the output of the drive motor 201 causes the connecting rod 206 to drive the push plate 208 to move upward. At this time, the push plate 208 lifts the feeding roller 3, so that the feeding roller 3 can automatically rise to the required installation position. This saves the steps of installing the feeding roller 3 that require multiple people, avoids the waste of labor costs, improves the convenience and flexibility of replacing the feeding roller 3, and makes it convenient for operators to use.

[0032] Example 2

[0033] like Figure 1-6 As shown, in one embodiment, a limiting rod 209 is fixedly installed on the front side of the top of the base plate 1. Two screw blocks 203 are slidably connected to the left and right sides of the limiting rod 209. The top of the base plate 1 is provided with a moving groove 210. The bottom of the four moving frames 205 are slidably connected to the inner cavity of the four moving grooves 210. The right side of the first guide roller 6 and the second guide roller 7 are fixedly connected with gears 8. The surfaces of the two gears 8 are meshed with each other. The left and right sides of the base plate 1 are threaded with anchor bolts 9. The bottom of the four anchor bolts 9 are threaded to the ground. The left and right sides of the top of the base plate 1 are movably connected with second flanges 11. The left and right sides of the discharge roller 3 are fixedly installed with first flanges 10. The two first flanges 10 are threadedly connected to the inner side of the two second flanges 11 by bolts.

[0034] By setting the limit rod 209, the movement of the screw block 203 can be limited to prevent the screw block 203 from deviating during movement, thus affecting the lifting work of the unloading roller 3. By setting the moving groove 210, the movement of the moving frame 205 can be limited to prevent the moving frame 205 from deviating during movement, thus affecting the lifting work of the unloading roller 3. By setting the anchor bolts 9, the overall equipment can be stabilized to prevent accidental collisions from affecting the unwinding work of the unloading roller 3. By setting the first flange 10 and the second flange 11, the unloading roller 3 can be quickly disassembled and assembled, making it easy to replace the material on the surface of the unloading roller 3 after it has been unwound.

[0035] In operation, when the feeding roller 3 needs to be installed, after placing the feeding roller 3 on the top of the push plate 208, the output of the drive motor 201 causes the bidirectional threaded rod 202 to rotate. The screw block 203 moves inward along the thread on the surface of the bidirectional threaded rod 202. At this time, the screw block 203 drives the connecting block 204 to move inward synchronously, thereby causing the moving frame 205 to move inward synchronously. The connecting rod 206 swings due to the movement of the moving frame 205 and pushes the U-shaped frame 207 upward. The U-shaped frame 207 drives the push plate 208 and the feeding roller 3 to move upward, causing the first flange 10 to move to the inside of the second flange 11. Then, the first flange 10 and the second flange 11 are connected by bolts, thereby completing the installation of the feeding roller 3.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
