Abstract
Description
Technical Field
[0001] This utility model relates to the field of winding device technology, and in particular to a winding device for biodegradable bags. Background Technology
[0002] Biodegradable films are a type of plastic mulch film that can be degraded by microorganisms under natural environmental conditions. After microorganisms such as bacteria, fungi, and actinomycetes erode the plastic film, the polymer components are hydrolyzed, ionized, or protonated due to cell growth, resulting in mechanical damage and fragmentation into oligomer fragments.
[0003] Biodegradable film is one of the main materials for bag making. Existing winding devices cannot be adjusted according to the size of fully biodegradable bags during winding, which results in significant limitations of existing winding devices. Utility Model Content

Drive teeth are fixedly sleeved on the drive wheel. The drive wheel is connected to the output shaft of a motor via a drive belt through the drive teeth. The motor is fixed to the lower surface of the base. A limit key is provided inside the drive wheel. A keyway is provided on the connecting rod, and the limit key engages with the keyway. A control plate is fixedly mounted between the output shaft of the cylinder on the same side and the connecting rod. A winding rod is fixedly mounted on the opposite side of the control plate, and the two winding rods cooperate with each other.
[0007] A further preferred embodiment of this utility model is: the winding rod layer is triangular-shaped, and the widths at both ends of the winding rod are different, with the opposite end of the winding rod having a smaller width.
[0008] A further preferred embodiment of this utility model is as follows: a through groove is provided in the middle of the base, and mounting grooves are provided on both sides of the through groove. A support plate is fixedly installed on the base through the mounting grooves.
[0009] A further preferred embodiment of this utility model is as follows: the support plate is L-shaped, and each vertical end of the support plate has a through hole, into which the winding rod is movably installed.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] according to Figure 1-4As shown, a winding device for biodegradable bags includes a base 1, with cylinders 2 fixedly mounted on both sides of the base 1. A mounting seat 3 is fixedly mounted on one side of each cylinder 2. A drive wheel 4 is rotatably mounted on one side of the mounting seat 3. A connecting rod 8 is rotatably mounted between the mounting seat 3 and the drive wheel 4. A drive gear 5 is fixedly sleeved on the outside of the drive wheel 4. The drive wheel 4 is connected to the output shaft of a motor 7 via the drive gear 5 and a drive belt 6. The motor 7 is fixed to the lower surface of the base 1. A limit key 15 is provided inside the drive wheel 4, and a keyway 9 is provided on the connecting rod 8. 5 cooperates with the keyway 9. This arrangement allows the connecting rod 8 to move left and right after the motor 7 stops working. Alternatively, when the cylinder 2 stops working, the motor 7 can drive the connecting rod 8 to rotate. Simultaneously, a control plate 10 is fixedly installed between the output shaft of the cylinder 2 on the same side and the connecting rod 8. This arrangement allows the cylinder 2 to cooperate with the control plate 10 to operate the winding rod 12 and the connecting rod 8 to move, which can better separate the fully biodegradable bag from the winding rod 12. The winding rod 12 is fixedly installed on the opposite side of the control plate 10, and the two winding rods 12 cooperate with each other.
[0021] The winding rod has 12 layers of triangular prisms, and the widths at both ends of the winding rod are different, with the opposite end of the winding rod being narrower. This design allows for better winding of the fully biodegradable bag, and also better separation from the fully biodegradable bag.
[0022] The base 1 has a through groove 14 in the middle, and mounting grooves are provided on both sides of the through groove 14. The base 1 is fixedly installed with a support plate 11 through the mounting groove. This configuration allows the size of the rolled-up fully biodegradable bag to be changed by adjusting the distance between the two support plates 11.
[0023] The support plate 11 is L-shaped, and each vertical end of the support plate 11 has a through hole. The winding rod 12 is movably installed in the through hole. This arrangement allows the winding rod 12 and the fully biodegradable bag to be separated by controlling the movement of the winding rod 12.
[0024] Each of the vertical ends of the support plate 11 is rotatably mounted with a baffle 13. This setting can limit the winding of the fully biodegradable bag and prevent the fully biodegradable bag from not being rolled up together.
[0025] The connecting rod 8 is rotatably connected to the control plate 10 via the rotating shaft 16. The connecting rod 8 is rotatably connected to the rotating shaft 16, and the rotating shaft 16 is fixedly connected to the control plate 10. This arrangement ensures that the connecting rod 8 can be rotated by the motor 7 and can also be moved by the cylinder 2.
[0026] Working principle: Adjust the distance between the support plates 11 according to the size of the fully biodegradable bag roll, and manually roll the fully biodegradable bag roll at one end onto the winding rod 12. Start the motor 7, and the motor 7 drives the transmission gear 5 to rotate through the transmission belt 6. The transmission gear 5 drives the connecting rod 8 to rotate, thereby causing the winding rod 12 to wind up. After winding is completed, turn off the motor 7 and start the cylinder 2. The cylinder 2 drives the control plate 10 to move to both sides, and at the same time, the winding rod 12 also moves to both sides, and the fully biodegradable bag roll is separated from the winding rod 12.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
