[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1-5 As shown, a buffer film feeding mechanism includes a frame 11; a cylinder 12 is fixedly connected to the top of the frame 11, the cylinder 12 has a feeding port 13 and a discharging port 14, a drive motor 15 is fixedly connected to the side of the cylinder 12, a drive seat 16 is fixedly connected to the output end of the drive motor 15, the drive seat 16 is located inside the cylinder 12, a bracket 17 is rotatably connected to the cylinder 12, and two baffles 18 are fixedly connected to the bracket 17; a hopper 51 is fixedly connected to the cylinder 12 at a position corresponding to the feeding port 13; a drive mechanism is provided on the bracket 17; one of the two baffles 18 corresponds to the position of the discharging port 14, and the other baffle 18 is located on the side of the feeding port 13; the drive mechanism includes a connecting shaft 22 and a servo motor 21, the servo motor 21 is fixedly connected to the side of the cylinder 12, the connecting shaft 22 is fixedly connected to the side of the bracket 17, and a synchronous belt is installed between the connecting shaft 22 and the output end of the servo motor 21;

[0025] In use, the operator places multiple rolls with buffer film on the hopper 51, and then they enter the housing through the feeding port 13. Then, the support 17 is rotated, which drives the baffle 18 to rotate. During feeding, the bottom baffle 18 rotates to block the discharge port 14, and the top baffle 18 is located on the side of the feeding port 13. During discharge, the drive causes the bottom baffle 18 to move to the side of the discharge port 14, so that the internal rolls can be released. At the same time, the top baffle 18 blocks the feeding port 13, which can reduce the friction between multiple rolls. With the above settings, the rolls can be automatically fed, which is convenient for operators to use.

[0026] The drive mechanism is driven by a servo motor 21 via a synchronous belt to rotate the connecting shaft 22 and the bracket 17, thereby driving the two baffles 18 to rotate.

[0027] Furthermore, such as Figure 2-3 As shown, it also includes an electric cylinder 31, a support arm 32, and a push rod 33. The electric cylinder 31 is fixedly connected to the cylinder body 12, the support arm 32 is fixedly connected to the output end of the electric cylinder 31, and the push rod 33 is fixedly connected to the end of the support arm 32. The push rod 33 passes through the end side wall of the cylinder body 12 and is slidably connected to it. The end of the push rod 33 is rotatably connected to a positioning seat 34, which is located inside the cylinder body 12. A guide rod 4 is fixedly connected to the side of the cylinder body 12, and a sliding sleeve is fixedly connected to the support arm 32 at a position corresponding to the guide rod 4. The guide rod 4 passes through the sliding sleeve, and the guide rod 4 and the sliding sleeve are slidably connected.

[0028] In use, the positioning seat 34 is installed at the end of the push rod 33. The push rod 33 drives the positioning seat 34 to push the drum, so that the end of the drum fits with the drive seat 16, thereby fixing the drum. This makes it easier for the drive seat 16 to drive the drum to rotate. The guide rod 4 and the sliding sleeve on the guide rod 4 can guide the support arm 32 and improve stability.

[0029] Furthermore, such as Figure 2-5 As shown, a guide frame 52 is fixedly connected to the top of the hopper 51, and the end of the guide frame 52 away from the cylinder 12 is inclined; the positioning seat 34 and the driving seat 16 are respectively located at both ends of the cylinder 12, and a guide groove 6 is provided at the end of the positioning seat 34 near the driving seat 16.

[0030] In use, the guide frame 52 is set up, and the guide frame 52 and the hopper 51 cooperate to facilitate the entry of the buffer film roll into the feed port 13, which makes it convenient for the staff to use. The end of the guide frame 52 is inclined, so the buffer film roll can enter the hopper 51. The guide groove 6 is installed on the side of the positioning seat 34, and the guide groove 6 cooperates with the side end of the roll, so that the roll can be located in the middle of the drive seat 16 and the positioning seat 34.

[0031] Furthermore, such as Figure 4 As shown, the side of the baffle 18 is fixed with a rubber sleeve 7. In use, the rubber sleeve 7 can play a protective role, thereby reducing the possibility of damage to the buffer membrane caused by the end of the baffle 18.

[0032] Working principle: During use, the operator places multiple rolls with buffer film on the hopper 51, and then they enter the housing through the feeding port 13. Then, the support 17 is rotated, which drives the baffle 18 to rotate. During feeding, the bottom baffle 18 rotates to block the discharge port 14, and the top baffle 18 is located on the side of the feeding port 13. During discharge, the drive causes the bottom baffle 18 to move to the side of the discharge port 14, allowing the internal rolls to come out. At the same time, the top baffle 18 blocks the feeding port 13, which can reduce the friction between multiple rolls. With the above settings, the rolls can be automatically fed, making it convenient for operators to use.

[0033] The drive mechanism is driven by a servo motor 21 via a synchronous belt to rotate the connecting shaft 22 and the bracket 17, thereby driving the two baffles 18 to rotate. In use, the positioning seat 34 is installed at the end of the push rod 33. The push rod 33 drives the positioning seat 34 to push the drum, so that the end of the drum fits against the drive seat 16, thereby fixing the drum. This makes it easier for the drive seat 16 to drive the drum to rotate. The guide rod 4 and the sliding sleeve on the guide rod 4 are used to guide the support arm 32 and improve stability. In use, the guide frame 52 is set. The guide frame 52 cooperates with the hopper 51 to facilitate the entry of the buffer film drum into the feed port 13, which is convenient for the operator. The end of the guide frame 52 is inclined, so the buffer film drum can enter the hopper 51. The guide groove 6 is installed on the side of the positioning seat 34. The guide groove 6 cooperates with the side end of the drum, so that the drum is located in the middle of the drive seat 16 and the positioning seat 34.
