[0019] Example 1: Please refer to Figure 1-4 A feeding device for a wrapping machine includes a base plate 12. Second electric telescopic rods 13 are installed on both sides of the top of the base plate 12. One end of each second electric telescopic rod 13 is bolted to a movable plate 16. The top of the movable plate 16 is hinged to a connecting plate 17 via a hinge. An insert rod 15 is installed at the middle position of the top of the base plate 12. A mounting platform 6 is provided at the top of the base plate 12, and a sleeve rod 14 is installed at the middle position of the bottom end of the mounting platform 6. A mounting groove 3 is formed on one side of the top of the mounting platform 6, and a screw is installed inside the mounting groove 3 via a bearing. The threaded rod 2 has a threaded block 18 sleeved on its outer side. A push plate 5 is provided on one side of the top of the mounting platform 6, and a servo motor 4 is installed on one side of the mounting platform 6. A groove 10 is opened on the side of the top of the mounting platform 6 away from the mounting groove 3, and multiple conveying wheels 9 are installed inside the groove 10 through bearings. Mounting plates 8 are provided at both ends of the top of the mounting platform 6, and multiple guide wheels 1 are installed at the top of the mounting plates 8 through bearings. Two fixing plates 7 are installed at both ends of the top of the mounting platform 6, and a first electric telescopic rod 11 is installed at one end of the fixing plate 7 through bolts.

[0020] One end of the first electric telescopic rod 11 is connected to one end of the mounting plate 8 by bolts, and the two mounting plates 8 are symmetrical about the vertical central axis of the conveyor wheel 9;

[0021] The output end of the servo motor 4 passes through one side of the mounting platform 6 and extends into the mounting groove 3, and the output end of the servo motor 4 is connected to one end of the threaded rod 2;

[0022] The top of the threaded block 18 passes through the top of the inside of the mounting groove 3 and is connected to the bottom of the push plate 5, and the bottom of the push plate 5 is in contact with the top of the mounting platform 6.

[0023] The top end of the insert rod 15 penetrates the bottom end of the sleeve rod 14 and extends into the inside of the sleeve rod 14, and the outer side of the insert rod 15 contacts the inner wall of the sleeve rod 14.

[0024] The top of the connecting plate 17 is hinged to one side of the bottom of the mounting platform 6 via a hinge, and the two connecting plates 17 are in an inverted octagon shape in space.

[0025] The top of the conveyor wheel 9 penetrates the inside top of the groove 10 and extends to the top of the mounting platform 6;

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in the operation of this device, firstly, the device, with the presence of the mounting platform 6, can drive the movable plate 16 to move horizontally by controlling the extension and retraction of the second electric telescopic rod 13. During the movement of the movable plate 16, the connecting plate 17 can be moved. Since both ends of the connecting plate 17 are hinged, and the vertical movement is restricted by the sleeve rod 14 and the insertion rod 15, the insertion rod 15 can drive the entire mounting platform 6 to move up and down during its movement. This allows for flexible adjustment of the height of the mounting platform 6, facilitating the transport of items requiring wrapping to packaging platforms of different heights. Then, with the presence of the push plate 5, the items requiring wrapping can be placed above the mounting platform 6. Then, by activating the servo motor 4, the threaded rod 2 can be rotated. Utilizing the rotation of the threaded rod 2 and the connection restriction of the push plate 5, the threaded block 1... 8 moves on the outside of the threaded rod 2, thereby driving the push plate 5 to move synchronously. During the movement of the push plate 5, the items can be moved synchronously, thus pushing them to perform the feeding work. In addition, this device is equipped with a conveyor wheel 9. During the feeding process, the rolling of the conveyor wheel 9 achieves a fast feeding effect and improves processing efficiency. Furthermore, this device is equipped with a mounting plate 8. The extension and retraction of the first electric telescopic rod 11 can drive the mounting plate 8 to move horizontally as a whole, thereby flexibly adjusting the distance between the two mounting plates 8. Then, the rolling of the guide wheel 1 provides a guiding function. During the feeding process, this device can effectively ensure the accuracy of the feeding position, prevent feeding deviation, improve the feeding quality of this device, and is quite convenient. In summary, this device has a good fast and stable feeding effect, is simple to operate, has a stable structure, a high degree of automation, and is quite practical.
