DETAILED DESCRIPTION

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0028] Please refer to Figure 1-4A film wrapping and bundling device for a film wrapping machine comprises a wrapping machine body 1, a vertically arranged partition 2 is provided in the wrapping machine body 1, the partition 2 is provided with a notch, a rotatable film wrapping disk 3 is provided on one side of the partition 2, the film wrapping disk 3 is C-shaped, and a detachable film roll 4 is provided on the film wrapping disk 3. When the film wrapping disk 3 rotates, the film roll 4 rotates accordingly; when in use, the film head on the film roll 4 is first wrapped around the object and then the film roll 4 is rotated, thereby bundling the film on the object.

[0029] In the solution of the present utility model, the partition 2 is provided with multiple outer limiting wheels 32 and inner limiting wheels 33 on one side of the film disk 3, the circumference of the film disk 3 is provided with meshing teeth 1 31, and driving wheels 34 are provided on both sides of the bottom of the partition 2. The circumference of the driving wheel 34 is provided with meshing teeth 2 341 that match the meshing teeth 1 31. In addition, the circumference of the film disk 3 is also provided with a recess, and the circumference of the driving wheel 34 is provided with an annular flange 342. The driving wheel 34 is matched with the film disk 3 through the annular flange 342; the outer circumference of the outer limiting wheel 32 also matches the recess of the circumference of the film disk 3, so that the rotation of the film disk 3 is more stable.

[0030] When the film winding disc 3 is in operation, at least one driving wheel 34 cooperates with the film winding disc 3 to provide power for the whole.

[0031] In addition, the film winding disk 3 is operated by a driving mechanism, which includes two synchronous pulleys 5 on the other side of the partition 2. The two synchronous pulleys 5 are coaxially connected to the corresponding driving wheels 34, and the two synchronous pulleys 5 are connected by a synchronous belt 6. One of the synchronous pulleys 5 is connected to the stepper motor 7; when the stepper motor 7 is running, the two synchronous pulleys 5 rotate accordingly, and when the synchronous pulleys 5 rotate, the driving wheel 34 on the other side of the partition starts to rotate; when the driving wheel 34 rotates, the film winding disk 3 is driven to rotate through the meshing teeth 1 31 and the meshing teeth 2 341, thereby realizing film bundling.

[0032] In order to prevent the synchronous belt 6 from loosening, the partition 2 is further provided with an adjustment plate 21 on the side close to the synchronous belt 6. The surface of the adjustment plate 21 is provided with a long waist groove 22. The adjustment plate 21 is fixedly connected to the partition 2 at the waist groove 22 by bolts. A tensioning wheel 23 is provided at the end of the adjustment plate. The circumference of the tensioning wheel 23 contacts the outer surface of the synchronous belt 6.

[0033] When the synchronous belt 6 is loose, first loosen the bolts to rotate the adjustment plate 21 downward. After rotation, the tensioning wheel 23 presses the synchronous belt 6. When the synchronous belt 6 is tightened, tighten the bolts, so that the cooperation between the synchronous belt 6 and the synchronous pulley 5 is more stable.

[0034] See also Figure 5-8 The film roll 4 is connected to the film winding disk 3 through a mounting buckle 41.

[0035] The mounting buckle 41 includes a fixing tube 411, a connecting piece 414 and a gasket 416. The fixing tube 411 and the connecting piece 414 are connected by a bolt 415. A screw 417 is provided in the gasket 416. The screw 417 extends into the fixing tube 411 through the gasket 416 and the connecting piece 414. A plane is provided on the circumference of the fixing tube 411, and an elastic piece 412 in the shape of an "X" is provided on the plane. The elastic piece 412 is connected to the fixing tube 411 by a screw 413. The elastic piece 412 is squeezed when the film roll 4 is installed.

[0036] The two ends of the gasket 416 are provided with mounting holes, and the film winding disk 3 is provided with bolts corresponding to the mounting holes, and the whole is installed on the film winding disk 3.

[0037] That is to say, the film roll 4 is installed in the mounting buckle 41 by plugging and pulling. After insertion, the elastic sheet 412 is compressed and deformed, and at the same time, its elastic force presses against the inner wall of the film roll, making the whole more stable; when replacing the film roll, it can be pulled out by external force.

[0038] Furthermore, in order to facilitate the adjustment of the tension of the film during bundling, elastic damping plates 4142 (elastic rubber pads) are provided on both sides of the gasket 416, and a blocking plate 4141 is provided on the outer side of the damping plate 4142. The end of the screw 417 is provided with an elastic ring 4171 and a nut 4172, and the nut 4172 is provided at the outermost end of the screw 417.

[0039] Since the film roll 4 is arranged on the outside of the fixed cylinder 411, and the fixed cylinder 411 is fixed by the screw 417 and the nut 4172, when the nut 4172 is tightened, the elastic ring 4171 and the damping plate 4142 will be squeezed to move the fixed cylinder 411 toward the film disk 3. At this time, the film on the fixed cylinder 411 will be further tightened; similarly, if you want to relax the film, loosen the nut 4172. At this time, the elastic ring 4171 and the damping plate 4142 will elastically open, and the fixed cylinder 411 will move in the opposite direction, so that the film will be relatively loose; this operation can adjust the tightness of the film, which is very practical and helps to improve the bundling quality.

[0040] In this embodiment, the tightness of the film cannot be clearly observed by naked eyes when the nut 4172 is tightened or loosened. The tightness adjustment of the film is a fine adjustment, and the specific adjustment is based on the actual bundling requirements.

[0041] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
