[0025] like Figure 1-3 As shown, this embodiment provides a packaging wrapping mechanism, including a lifting rod 204, a handle 214, a first film support wheel 201, a second film support wheel 202, and a wrapping cylinder 203. The lifting rod 204 passes sequentially through the first film support wheel 201, the wrapping cylinder 203, and the second film support wheel 202. The handle 214 is located at the top of the lifting rod 204. The wrapping cylinder 203 is located between the first film support wheel 201 and the second film support wheel 202. The first film support wheel 201 is connected to the upper end of the wrapping cylinder 203, and the second film support wheel 202 is connected to the lower end of the wrapping cylinder 203. The wrapping film 60 is wound around the wrapping cylinder 203.

[0026] Preferably, the first film support wheel 201 is engaged with the upper end of the winding cylinder 203, and the lower diameter of the first film support wheel 201 is adapted to the diameter of the winding cylinder 203. The second film support wheel 202 is engaged with the lower end of the winding cylinder 203, and the upper diameter of the second film support wheel 202 is adapted to the diameter of the winding cylinder 203. This precise matching design ensures stable operation of the film winding throughout the entire winding process, reduces the possibility of deviation or slippage, and thus improves the stability of the film winding.

[0027] Preferably, it also includes a winding shaft 205, which is disposed inside the winding cylinder 203 and sleeved on the outside of the lifting rod 204. The inner diameter of the lifting rod 204 is smaller than the inner diameter of the winding shaft 205. The winding shaft 205 is a hollow tube, and the inner diameter of the winding shaft 205 is smaller than the inner diameter of the winding cylinder 203.

[0028] Preferably, it also includes a baffle 206, which is disposed at the end of the lifting rod 204. The winding shaft 205 has an elongated hole 209 on its side wall parallel to the shaft center line. Several locking grooves 210 are provided on both sides of the elongated hole 209, and the locking grooves 210 are adapted to the baffle 206.

[0029] In this embodiment, the lifting rod 204 is provided to adjust the height of the winding mechanism, which allows the device to adapt to products of different heights, thus improving the flexibility and applicability of the device. The baffle 206 is provided at the end of the lifting rod 204, and on the other hand, it plays a role in preventing the winding shaft 205 from accidentally falling off, especially under high-speed operation or heavy load conditions.

[0030] Preferably, it also includes a first bearing 207, which is disposed at the center of the first membrane support wheel 201 and is sleeved on the outside of the upper end of the winding shaft 205.

[0031] Preferably, it also includes a second bearing 208, which is disposed at the center of the second membrane support wheel 202 and is sleeved on the outside of the lower end of the winding shaft 205.

[0032] Preferably, it also includes a locking retaining ring 211 and a locking nut 212, wherein the locking retaining ring 211 is detachably mounted on the lifting rod 204 via the locking nut 212.

[0033] Preferably, it also includes a pressure spring 213, one end of which is connected to the locking retaining ring 211, and the other end of which is connected to the first bearing 207.

[0034] Preferably, there are two slots 210, which are respectively located above and below the winding shaft 205.

[0035] The working process of this utility model is as follows:

[0036] Pulling the lifting rod 204 with handle 214 simultaneously moves the baffle 206, the first film support wheel 201, and the second film support wheel 202, causing the baffle 206 to engage in the locking slots 210 at different heights, thus adjusting the height of the wrapping film 60 to accommodate goods of varying heights. After adjustment to the appropriate position, the first film support wheel 201 is engaged with the upper end of the wrapping cylinder 203, and the second film support wheel 202 is engaged with the lower end of the wrapping cylinder 203. Then, the locking nut 212 is used to tighten the locking ring 211, ensuring that the wrapping mechanism does not loosen or shift during operation. The wrapping film 60 is continuously released to package the goods as the wrapping cylinder 203 rotates. The first bearing 207 and the second bearing 208 are designed to allow the first film support wheel 201 and the second film support wheel 202 to rotate more smoothly. The pressure spring 213 adjusts the tension of the first film support wheel 201, thereby ensuring that the wrapping film 60 maintains appropriate tension throughout the wrapping process, avoiding excessive looseness or tightness, which helps to improve the quality of packaging and ensures that the wrapping film 60 is evenly and tightly wrapped on the surface of the goods.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
