The stretch film frame 220 fixes the adjustment assembly 400 by the first connecting bar 310, the second connecting bar 320 and the fixing member 330, and improves the convenience of replacing the stretch film. The stretching film barrel is fixedly installed through the adjusting assembly 400, and the application range of the stretching film barrel is widened.

The adjusting assembly 400 is mounted on the stretch film frame 220 by a first connecting rod 310 and a second connecting rod 320, and the first connecting rod 310 is fixed to the first mounting block 221 by a fixing member 330. The fixing member 330 allows the first connecting rod 310 to be stably mounted in the fixing groove 222 by being inserted into the positioning through hole 223 and the fixing hole 311. When the fixing member 330 is removed, the second connecting rod 320 is rotatably connected to the second mounting block 224, so that the adjusting assembly 400 is rotatably connected to the stretch film frame 220, and the adjusting assembly 400 can be easily laid down to replace the stretch film tube mounted on the adjusting assembly 400.

The relative positions of the second main lever case 430 and the second sub-lever case 440, i.e., the distance between the main rotating lever 470 and the sub-rotating lever 480, are maintained by adjusting the threaded connection relationship of the ring member 460 and the adjustment lever 442. In one embodiment, the spring member 450 is a compression spring and the adjustment rod 442 extends through the spring member 450. The tightness of the threaded connection of the adjustment ring 460 to the adjustment rod 442 is further enhanced by the spring action of the spring member 450.

The tensile membrane cylinder is fixed by sleeving the inner cylinder of the tensile membrane cylinder in the main rotary cylinder 471 and the auxiliary rotary cylinder 481. By screwing the adjusting ring member 460, the adjusting rod 442 is driven by utilizing the threaded relationship between the adjusting ring member 460 and the adjusting rod 442, that is, the relative position between the second main rod shell 430 and the second auxiliary rod shell 440 is adjusted, so that the relative distance between the main rotating rod 470 and the auxiliary rotating rod 480 is controlled, the inner cylinders of the stretching film cylinders with different sizes are adapted, and the application range is widened.

In order to enhance the stability of the connection between the first main rod case 410 and the first connecting rod 310, in one embodiment, the first main rod case 410 and the first connecting rod 310 are integrally formed. Thus, the first main rod case 410 is firmly coupled to the first connecting rod 310 and is not easily separated therefrom. Further, in order to enhance the connection stability of the second main lever housing 430 and the second connecting lever 320, in one embodiment, the second main lever housing 430 and the second connecting lever 320 are integrally formed. Thus, the second main lever housing 430 is firmly coupled to the second connecting lever 320 and is not easily separated therefrom. Thus, the structural strength of the winding mechanism 200 is improved.

In order to prevent the adjusting ring 460 from being separated from the adjusting hole 432, in one embodiment, the second main rod casing 430 is formed with a limiting ring groove 433 on an inner wall of the adjusting hole 432, the adjusting ring 460 is provided with a limiting ring block 461, and the limiting ring block 461 is inserted into the limiting ring groove 433 and is rotatably connected with the second main rod casing 430. Thus, the limiting ring groove 433 limits the limiting ring block 461 to prevent the adjusting ring 460 from separating from the adjusting hole 432. In this manner, the stability of the rotational connection of the adjustment ring 460 to the second spindle housing 430 is improved.

In order to facilitate the user to twist the adjustment ring 460, in one embodiment, the portion of the adjustment ring 460 exposed from the adjustment hole 432 has a prism structure. Therefore, a user can conveniently clamp the adjusting ring piece 460 by using tools such as a wrench and the like, the convenience degree of screwing the adjusting ring piece 460 is improved, and the adjusting convenience is improved. In this manner, it is convenient for the user to twist the adjustment ring 460.

In order to avoid the sliding of the main rotating shaft 471 along the length direction of the main rotating shaft 470, in one embodiment, the main rotating shaft 470 is provided with a first stop ring block 472, the inner wall of the main rotating shaft 471 is provided with a first stop ring groove 473, and the first stop ring block 472 is inserted into the first stop ring groove 473 and is rotatably connected with the main rotating shaft 471. The first stop ring groove 473 limits the first stop ring block 472, so as to prevent the main rotating cylinder 471 from sliding along the length direction of the main rotating rod 470. Further, in order to avoid the sliding of the sub rotary drum 481 along the length direction of the sub rotary shaft 480, in one embodiment, the sub rotary shaft 480 is provided with a second stop ring block 482, the inner wall of the sub rotary drum 481 is provided with a second stop ring groove 483, and the second stop ring block 482 is inserted into the second stop ring groove 483 and is rotatably connected with the sub rotary drum 481. The second stop ring groove 483 limits the second stop ring block 482 to prevent the auxiliary rotating barrel 481 from sliding along the length direction of the auxiliary rotating rod 480. Thus, the working stability of the winding mechanism 200 is improved.
