[0002] Woven bags are a type of plastic bag. Their main materials are high molecular compounds such as polypropylene and polyethylene. These materials are processed into packaging products with various colors and patterns through specific processes such as plastic weaving, color printing, and lamination. Plastic woven bags are a type of woven bag. In the production process of plastic woven bags, a winding and storage device is used to roll up and wrap the woven bags for storage.

[0003] For example, the patent with publication number CN218201229U (a plastic woven bag winding and storage device) includes a support base, a replaceable winding and storage mechanism and a tension limiting mechanism. The replaceable winding and storage mechanism is disposed on the support base, and the tension limiting mechanism is disposed on the side wall of the support base.

[0004] While the aforementioned existing technology has solved the problem of insufficient tension on the woven bags during the winding process, resulting in excessively large storage rollers that make it difficult to store them, it is also inconvenient to remove and store the plastic woven bags after they have been wound, making it impractical. Therefore, there is an urgent need in the market to develop a plastic woven bag winding and storage device to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic woven bag winding and storage device to solve the problem mentioned in the background art that after the plastic woven bags are rolled up and wound, it is inconvenient to remove them for unified storage, resulting in poor practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic woven bag winding and storage device, comprising a device frame, characterized in that: the device frame includes a base plate, a first upright plate, a strip plate, and a second upright plate; the first upright plate is fixedly installed on one side above the base plate; the strip plate is disposed on one side of the base plate; the second upright plate is fixedly installed above the strip plate; an air-expanding roller is rotatably installed on one side of the first upright plate; a plate cavity is provided inside the base plate; a translation plate is provided inside the plate cavity, and the translation plate is fixedly connected to the strip plate; a handwheel is provided at the front end of the base plate; a threaded rod is fixedly installed at the rear end of the handwheel; the rear end of the threaded rod is threadedly connected to the base plate and passes into the plate cavity to contact the translation plate; a side column is fixedly installed on one side of the air-expanding roller; a matching sleeve is sleeved on the outer side of the side column; a fixed seat is rotatably installed on one side of the outer side of the matching sleeve; and the fixed seat is fixedly connected to the second upright plate.

[0007] Preferably, a roller frame is provided above the air expansion roller, a pressure roller is rotatably installed on the inner side of the roller frame, a flat plate is provided above the roller frame, and compression springs are symmetrically fixed on both sides between the roller frame and the flat plate.

[0008] Preferably, a top plate is provided above the flat plate, the top plate is fixedly connected to the vertical plate, and an electric cylinder is fixedly installed above the top plate. The push rod end of the electric cylinder slides through the top plate and is fixedly connected to the flat plate.

[0009] Preferably, each of the two compression springs has a guide post inside. The lower end of the guide post is fixedly connected to the roller frame, and the upper end of the guide post slides through the flat plate and the top plate in sequence. A limit plate is fixedly installed on the upper end of the guide post.

[0010] Preferably, a base box is fixedly installed above the base plate, a support base is provided above the base box, and an arc-shaped groove is provided on the upper surface of the support base.

[0011] Preferably, a square tube is fixedly installed below the support base, the lower end of the square tube extends into the interior of the base box, and a hydraulic cylinder is fixedly installed in the lower middle of the interior of the base box, with the piston rod end of the hydraulic cylinder fixedly connected to the support base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model allows for the adjustment of the positions of the strip plate and the translation plate via a handwheel and threaded rod mechanism. This facilitates the installation of the roll for wrapping plastic woven bags before winding and allows for further adjustment after winding to ensure that the roll with the plastic woven bags can be easily removed from the air roller. The design of the roll further enhances the stability of the air roller during the winding process, ensuring winding quality, improving operational convenience, and enhancing the practicality and flexibility of the device. This enables the easy and unified storage and management of a large number of wound plastic woven bags.

[0014] This utility model features a roller frame with a pressure roller, and a compression spring between the roller frame and the upper plate. During the winding process of the plastic woven bag, the roller frame and pressure roller above the air-expanding roller drive the plate to move downwards. With the help of the elasticity of the compression spring, the pressure roller can elastically press tightly against the surface of the plastic woven bag during the winding process. This not only ensures the tight fit of the plastic woven bag during the winding process and reduces the problem of uneven winding caused by slack, but also makes the woven bag roll more compact.

[0015] This utility model features a base box and support seat installed above the base plate, along with an arc-shaped groove, which provides a stable support surface for the bottom of the plastic woven bag. The arc-shaped groove also conforms to the shape of the roll, supporting the bottom of the wound plastic woven bag after it has been wound. This facilitates the removal and storage of the plastic woven bag after winding and prevents the air roller from bending due to gravity during the removal process, thus increasing its practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4This utility model provides an embodiment of a plastic woven bag wrapping and storage device, including a device frame. The device frame includes a base plate 1, a first upright plate 2, a strip plate 4, and a second upright plate 5. The first upright plate 2 is fixedly installed on one side above the base plate 1. The strip plate 4 is disposed on one side of the base plate 1. The second upright plate 5 is fixedly installed above the strip plate 4. An air expansion roller 3 is rotatably installed on one side of the first upright plate 2, and a drive motor for the air expansion roller 3 is disposed on the other side of the first upright plate 2. The base plate 1 has a plate cavity 101 inside. The cavity 101 is equipped with a translation plate 7, which is fixedly connected to the strip plate 4. The front end of the base plate 1 is equipped with a handwheel 6, and the rear end of the handwheel 6 is fixedly installed with a threaded rod. The rear end of the threaded rod is threadedly connected to the base plate 1 and passes into the cavity 101 to contact the translation plate 7. A side column 19 is fixedly installed on one side of the air roller 3. A mating sleeve 20 is sleeved on the outside of the side column 19. A fixed seat 21 is rotatably installed on one side of the outside of the mating sleeve 20. The fixed seat 21 is fixedly connected to the vertical plate 5.

[0023] In use, when storing plastic woven bags, loosen the threaded rod by handwheel 6, pull the translation plate 7 and strip plate 4 to one side, and place the roll for winding the plastic woven bags onto the air expansion roller 3. Then drive the strip plate 4 to return to its original position. The matching cylinder 20 can support one side of the air expansion roller 3, increasing the stability of winding the plastic woven bags. Then drive the air expansion roller 3 to rotate to wind the plastic woven bags. After winding, drive the strip plate 4 to move the vertical plate 5 away from the air expansion roller 3, so that the roll with the plastic woven bags can be removed from one side of the air expansion roller 3, which facilitates the unified storage of a large number of wound plastic woven bags.

[0024] Furthermore, a roller frame 10 is provided above the air-expanding roller 3, and a pressure roller 11 is rotatably installed on the inner side of the roller frame 10. A flat plate 9 is provided above the roller frame 10, and compression springs 12 are symmetrically fixed on both sides between the roller frame 10 and the flat plate 9. A top plate 8 is provided above the flat plate 9, and the top plate 8 is fixedly connected to the vertical plate 2. An electric cylinder 14 is fixedly installed above the top plate 8. The push rod end of the electric cylinder 14 slides through the top plate 8 and is fixedly connected to the flat plate 9. This allows the pressure roller 11 to elastically press tightly against the surface of the plastic woven bag during the winding process by combining the roller frame 10 and the pressure roller 11 above the air-expanding roller 3, driving the flat plate 9 downward through the electric cylinder 14, and with the help of the elastic action of the compression springs 12. This not only ensures the tight fit of the plastic woven bag during the winding process and reduces the problem of uneven winding caused by slack, but also makes the woven bag roll tighter.

[0025] Furthermore, each of the two compression springs 12 is equipped with a guide post 13. The lower end of the guide post 13 is fixedly connected to the roller frame 10, and the upper end of the guide post 13 slides through the flat plate 9 and the top plate 8 in sequence. A limit plate is fixedly installed on the upper end of the guide post 13. The guide post 13 provides a stable guiding function for the compression spring 12, preventing the compression spring 12 from shifting laterally when compressed. At the same time, the cooperation between the guide post 13 and the limit plate also limits the maximum stroke of the compression spring 12, protecting the compression spring 12 from excessive stretching and extending its service life.

[0026] Furthermore, a base box 15 is fixedly installed above the base plate 1, and a support seat 16 is provided above the base box 15. An arc-shaped groove is provided on the upper surface of the support seat 16. The base box 15, support seat 16 and the arc-shaped groove on the base plate 1 provide a stable support surface for the bottom of the plastic woven bag. The arc-shaped groove is also designed to fit the shape of the roll, which can support the bottom of the wound plastic woven bag after it is wound. This is beneficial for the removal and storage of the plastic woven bag after it is wound, and prevents the air roller 3 from bending due to gravity during the removal of the plastic woven bag, thus increasing its practicality.

[0027] Furthermore, a square tube 17 is fixedly installed below the support base 16. The lower end of the square tube 17 extends into the interior of the bottom box 15. A hydraulic cylinder 18 is fixedly installed in the lower middle of the interior of the bottom box 15. The piston rod end of the hydraulic cylinder 18 is fixedly connected to the support base 16. The height of the support base 16 can be flexibly adjusted by driving the extension and retraction of the piston rod end of the hydraulic cylinder 18, thereby adapting to woven bags of different thicknesses or heights that have been wound and wrapped. At the same time, the hydraulic drive method is more labor-saving and faster than manual adjustment, improving the automation level of the entire storage device.

[0028] Working principle: During use, the frame consisting of base plate 1, upright plate 1, upright plate 2, and strip plate 4 provides support for the overall structure. The air roller 3 is driven by a motor to rotate and is used for winding the plastic woven bag. Before winding, the threaded rod is loosened by handwheel 6, and then the translation plate 7 and strip plate 4 are pulled to one side to put the roll onto the air roller 3. Then, the strip plate 4 is driven to return to its original position. The side column 19 on one side of the air roller 3 provides auxiliary support through the matching cylinder 20 to enhance the stability during the winding process. During the winding process, the electric cylinder 14 drives the plate 9 to move down. Through the elastic action of the compression spring 12, the pressure roller 11 is pressed tightly against the surface of the woven bag to ensure tight winding and reduce slack. After winding is completed, the hydraulic cylinder 18 drives the support seat 16 to rise. The arc groove on it provides support for the bottom of the woven bag, making it easy to stably remove the woven bag roll from the air roller 3.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
