The zipper bag body passes between the two opposite clamping plates. Under the action of the torsion spring, the two clamping plates tighten the zipper bag body that is in a winding state and has been wound around the outer ring of the winding shaft.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] 1. The utility model drives the winding shaft to rotate by twisting the toggle block, thereby realizing winding and storing the zipper bag body connected to the winding shaft. At the same time, under the action of the torsion spring, the two clamping plates are forced to press against the outer wall of the rolled zipper bag body, ensuring that the zipper bag body in the rolled state will not loosen and the zipper bag body in the rolled state will be neatly rolled without manual folding. At the same time, the winding storage will not cause air bubbles to be squeezed and ruptured, ensuring that the zipper bag will remain unchanged when it is used next time.

[0017] 2. When the zipper bag body passes through the opening, the inner wall of the opening fits against the outer wall of the zipper bag body. In this way, during the rolling process, the opening cleans the outer wall of the zipper bag body, preventing impurities attached to the outer wall of the zipper bag body from being rolled up together, thereby ensuring that the zipper bag body is neat for subsequent use.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-5 The composite bubble film zipper bag shown includes a zipper bag body 1, a zipper head 2 is provided at the open end 102 at the front end of the zipper bag body 1, a tip 101 at the tail end of the zipper bag body 1 is provided inside a winding barrel 3, a winding shaft body 6 is rotatably connected to the inside of the winding barrel 3, the tip 101 is fixedly connected to the outer wall of the winding shaft body 6, a toggle block 7 is fixedly connected to the top of the winding shaft body 6, a cavity 5 is provided inside the winding barrel 3, an opening 4 is provided on one side of the winding barrel 3, wherein the zipper bag body 1 passes through the opening 4 area, a notch 9 is provided inside the winding barrel 3, and the notch 9 is connected to the cavity 5, and further includes:

[0028] The anti-loosening limit assembly 8 includes a fixed shaft 801. The inner wall of the notch 9 is fixedly connected to the fixed shaft 801. The outer ring of the fixed shaft 801 is movably sleeved with a clamping plate 802 through a bearing to ensure that the zipper bag body 1 is rolled up and not loose.

[0029] The inner wall of the opening 4 fits against the outer wall of the zipper bag body 1 passing through the opening 4, and the gap between the inner wall of the opening 4 is smaller than the gap between the two outer walls of the zipper head 2, so that one section of the zipper bag body 1 is located outside the winding barrel 3 without affecting the overall winding operation, making it convenient for subsequent use to pull the entire zipper bag body 1 out of the winding barrel 3 through the exposed small section of the zipper bag body 1.

[0030] The lower end of the winding shaft 6 is rotatably connected to the inner wall of the cavity 5 through a bearing, and the upper end of the winding shaft 6 extends to the area outside the winding barrel 3. The outer wall of the upper end of the winding shaft 6 and the through-opening at the top of the winding barrel 3 are rotatably connected through a bearing. The vertical center axis position of the winding shaft 6 coincides with the vertical center axis position of the winding barrel 3, so that the rotation of the winding shaft 6 can rewind the zipper bag main body 1 connected to the winding shaft 6.

[0031] The bottom of the toggle block 7 is in contact with the top wall of the winding barrel 3 and is rotatably connected thereto. The edge of the toggle block 7 is provided with serrations 701 to facilitate subsequent toggle of the toggle block 7 .

[0032] There are two fixed shafts 801 , which are symmetrically arranged with reference to the vertical center axis of the winding barrel 3 . The upper and lower ends of the fixed shafts 801 are fixedly connected to the top wall and bottom wall of the notch 9 respectively.

[0033] The outer ring of the fixed shaft 801 is provided with a torsion spring, and the two ends of the torsion spring are fixedly connected to the inner wall of the notch 9 and the clamping plate 802 respectively. The torsion spring applies force to tighten the two clamping plates 802 to the zipper bag body 1 being wound.

[0034] The end of the clamping plate 802 that contacts the tip 101 is an arc-shaped smooth surface, and the arc-shaped ends of the two clamping plates 802 that contact the tip 101 are opposite to each other. The zipper bag body 1 passes through the two opposite clamping plates 802. Under the action of the torsion spring, the two clamping plates 802 tighten the zipper bag body 1 that is in the winding state and has been wound around the outer ring of the winding shaft 6.

[0035] Working principle: When using a composite bubble film zipper bag, first, the toggle block 7 is twisted to drive the rotation of the reeling shaft 6 fixedly connected to the lower end of the toggle block 7, and then the zipper bag main body 1 connected to the reeling shaft 6 is wound and stored. In the process of the zipper bag main body 1 being rolled through the opening 4, the inner wall of the opening 4 fits the outer wall of the zipper bag main body 1. In this way, during the rolling process, the opening 4 cleans the outer wall of the zipper bag main body 1, preventing impurities attached to the outer wall of the zipper bag main body 1 from being rolled together, thereby ensuring the safety of the bag. To ensure that the zipper bag body 1 is neat in subsequent use, as the zipper bag body 1 wrapped around the outer circle of the winding shaft 6 becomes thicker, the zipper bag body 1 in the wound state stretches out the two clamping plates 802, and at the same time, under the action of the torsion spring, the two clamping plates 802 are forced to cling to the outer wall of the rolled-up zipper bag body 1, ensuring that the zipper bag body 1 in the rolled-up state will not loosen, and ensuring that the zipper bag body 1 in the rolled-up state is rolled neatly, which will not cause the bubbles in the bubble film to burst, and effectively ensure that the zipper bag has a better subsequent use effect.

[0036] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
