Specific embodiments

[0023] Now, the present utility model will be further described in detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0024] Please refer to Figures 1-9 , a film wheel mounting structure for a semi-automatic film bundling machine, including a lower box body 1 and an upper box body 2. A vertical vertical plate 3 is provided inside the lower box body 1, and the vertical plate 3 extends into the upper box body 2. A rotatable annular gear 4 is provided on one side of the vertical plate 3. The annular gear 4 is in a C shape, and a mounting structure 7 for detachable film wheel 6 is provided on the annular gear 4. A notch 12 is provided on the surface of the lower box body 1, and the film 61 on the film wheel 6 extends outward at the notch 12. When the annular gear 4 rotates, the film 61 is wound around the workpiece. When in use, the workpiece to be bundled is placed at the notch on the surface of the lower box body.

[0025] Specifically, the installation structure 7 includes a horizontal main shaft 71. One end of the main shaft 71 is fixed on the annular gear 4, and the other end is provided with a threaded hole 73. A connecting disc 77 is arranged outside the main shaft 71. Inside the connecting disc 77, there is a stud that is integrated and matches the threaded hole 73. The connecting disc 77 is detachably connected to the main shaft 71 at the threaded hole 73 through the stud. When the connecting disc is disassembled, the film wheel 6 is sleeved and installed on the main shaft 71. During use, first, stick the film end in the notch 12 to the workpiece. When the annular gear 4 starts to rotate, the film wheel 6 on the annular gear 4 also rotates along the rotation trajectory. During this movement process, the film 61 on the film wheel 6 will continuously extend outwards and wind around the workpiece, thereby packaging and bundling the workpiece. After bundling, cut the film.

[0026] During the rotary bundling process, in order to ensure that the position of the film wheel 6 does not shift and improve the bundling quality, a limiting disc 72, a rotating cylinder 75, and a pressing disc 74 are also provided on the circumference of the main shaft 71. The limiting disc 72 is fixed on the main shaft 71. The pressing disc 74 is sleeved on the main shaft 71. The rotating cylinder 75 is rotatably arranged between the limiting disc 72 and the pressing disc 74. A compression spring 76 is arranged between the pressing disc 74 and the connecting disc 77, and the compression spring 76 is always in a compressed state. The film wheel 6 is arranged around the rotating cylinder 75. Since the compression spring 76 is in a compressed state, the compression spring 76 will push the pressing disc 74 to fit one side of the film wheel 6, and the other side of the film wheel 6 will fit the limiting disc 72. Therefore, the film wheel 6 is always between the limiting disc 72 and the pressing disc 74. During the rotary bundling process, the film wheel 6 will not shift horizontally, and the stability is strong, ensuring the bundling quality.

[0027] In this embodiment, on one side of the annular gear 4 of the vertical plate 3, there are a plurality of outer limiting wheels 31 and inner limiting wheels 32. On the outer circumference of the annular gear 4, there are an outer limiting groove 41 and meshing teeth 42. The outer limiting wheels 31 always cooperate with the outer limiting groove 41, and the inner limiting wheels 32 always contact the inner circumference of the annular gear 4. Below the vertical plate 3, there are also two driving gears 33, and the driving gears 33 always cooperate with the meshing teeth 42.

[0028] That is to say, the outer circumference of the annular gear 4 is limited by the outer limiting wheels 31, the inner circumference is limited by the inner limiting wheels 32, and the annular gear 4 rotates through the driving gears 33 below, so as to ensure the stability of the annular gear 4 during rotary bundling.

[0029] In addition, on the side of the vertical plate 3 away from the annular gear 4, there are a driving pulley 51 and a driven pulley 52. The driving pulley 51 and the driven pulley 52 respectively correspond to the driving gears 33 on the other side of the vertical plate 3. The driving pulley 51 and the driven pulley 52 are connected by a synchronous belt 53, and the driving pulley 51 is driven by an outer motor 5.

[0030] After the motor 5 runs, the driving pulley 51 and the driven pulley 52 drive the corresponding driving gear 33 to rotate. The rotation of the driving gear 33 drives the rotation of the annular gear 4, and the rotation of the annular gear 4 causes the film wheel 6 to rotate for film bundling.

[0031] As a preferred solution, handles are provided on both sides of the lower box body 1 for easy overall handling and movement. A heat dissipation groove 13 is provided on the inner bottom surface of the lower box body 1 for internal heat dissipation.

[0032] When the whole is in use, the workpiece to be bundled is held by both hands of an operator and placed on the surface of the lower box body 1 at the notch of the annular gear 4. Then, the end of the film 61 is first adhered to the workpiece. Next, the motor is started. After the motor runs, it drives the annular gear 4 to rotate. When the annular gear 4 rotates, the film wheel 6 rotates accordingly, so as to wind the film 61 layer by layer onto the surface of the workpiece; after the film bundling is completed, the film can be cut; when the film on the film wheel 6 is used up, open the top cover of the lower box body 1 or the side cover of the upper box body. After opening, rotate the connecting disc 77, take out the compression spring 76, the extrusion disc 74 and the used film wheel 6, then install the new film wheel 6, and then install the extrusion disc 74, the compression spring 76 and the connecting disc 77 in sequence. While ensuring the position of the film wheel 6, it is also convenient for installation and disassembly, which is beneficial to replacing the film wheel 6 and is suitable for popularization and use.

[0033] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the creative utility model.
