[0002] Long-fiber PP composites are composite materials whose mechanical properties are enhanced by incorporating long glass fibers (LGF) or other long fibers (such as carbon fibers) into a polypropylene (PP) matrix. During transportation, a thin film needs to be wrapped around the outer surface of the long-fiber PP composite to prevent it from collapsing or falling during transport.

[0003] The application of a stretch wrapping device is necessary for coating the outer surface of long-fiber PP composite materials. This device is used to secure and protect goods using stretch or wrapping film, and is widely used in logistics, warehousing, and manufacturing industries. The stretch wrapping device mainly consists of a handheld frame, a rotating shaft, and auxiliary rods. Its primary function is to tightly wrap goods using the stretch and contraction properties of the wrapping film, thereby achieving dustproofing, moisture protection, shockproofing, and reducing transportation losses.

[0004] Regarding the above technical conditions, there is also a drawback: the rotating shaft is installed on the handheld frame with screws and nuts, which makes it inconvenient to disassemble and replace the rotating shaft.

[0005] Based on this, the present invention designs a long fiber PP composite material winding device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a long fiber PP composite material winding device to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a long-fiber PP composite material winding device, comprising a handheld frame, a rotating shaft, and an auxiliary rod for the winding packaging device. The rotating shaft is connected to the handheld frame, and the auxiliary rod is rotatably connected to the handheld frame. The rotating shaft is located between the handheld frame and the auxiliary rod. Two fixed rods are rotatably connected to the rotating shaft, and the two fixed rods are respectively disposed at both ends of the rotating shaft. A fixing hole is provided on the handheld frame, and the fixed rod is inserted into the fixing hole. A positioning groove is provided on the handheld frame, and the fixing hole is located in the positioning groove. A positioning plate is connected to one end of the fixed rod, and the positioning plate abuts against the positioning groove. The fixing hole is located between the positioning plate and the rotating shaft. A through hole is provided in the positioning groove, and the through hole communicates with the fixing hole. The fixed rod includes an upper rod and a lower rod. The lower rod is rotatably connected to the rotating shaft and inserted into the upper rod. The positioning plate is fixedly connected to the upper rod. A spring is fixedly connected to the upper rod, and the spring is fixedly connected to the lower rod. The spring is in a stretched state.

[0008] Preferably, a limiting groove is provided on the lower rod, and two limiting grooves are mirror images of each other on the lower rod. A limiting block is fixedly connected to the upper rod, and the limiting block is inserted into the limiting groove.

[0009] Preferably, the positioning groove has a snap-fit ​​groove, and the positioning plate is located in the snap-fit ​​groove.

[0010] Preferably, the positioning plate has an auxiliary slot, and two auxiliary slots are mirror-arranged on the positioning plate.

[0011] Preferably, the positioning plate is narrow in the middle and wide at both ends.

[0012] In summary, this application has the following beneficial technical effects: When disassembling the rotating shaft, the positioning plate on one side of the handheld frame is pulled outward through the auxiliary groove, so that the positioning plate leaves the snap-fit ​​groove. Then, the positioning plate is rotated so that the positioning plate is parallel to the through hole. The positioning plate is released, the spring contracts, and under the contraction of the spring, the upper rod moves in the direction of the lower rod. The positioning plate is carried away from the through hole by the upper rod, and the positioning plate is removed from the handheld frame. Then, the above operation is repeated to remove the positioning plate on the other side of the handheld frame from the handheld frame. In this way, the rotating shaft is completely removed from the handheld frame, achieving the effect of conveniently disassembling and replacing the rotating shaft of the wrapping packaging device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is in conjunction with the appendix Figs. 1-3 This application will be described in further detail.

[0021] A long-fiber PP composite material winding device includes a handheld frame 5, a rotating shaft 4, and an auxiliary rod 3. The rotating shaft 4 is connected to the handheld frame 5, and the auxiliary rod 3 is connected to the handheld frame 5. The rotating shaft 4 is located between the auxiliary rod 3 and the handheld frame 5. A film roll is placed on the rotating shaft 4, and the film is wound around the object. The auxiliary rod 3 keeps the film flat during winding.

[0022] Two fixed rods 2 are rotatably connected to the rotating shaft 4, and the two fixed rods 2 are respectively located at both ends of the rotating shaft 4. The handheld frame 5 has a fixing hole 11, and the fixing rods 2 are inserted into the fixing hole 11. A positioning groove 6 is provided on the side of the handheld frame 5 away from the rotating shaft 4, and the fixing hole 11 is located in the positioning groove 6.

[0023] A positioning plate 8 is connected to the end of the fixing rod 2 away from the rotating shaft 4. The positioning plate 8 abuts against the positioning groove 6, and the fixing hole 11 is located between the positioning plate 8 and the rotating shaft 4. A through hole 1 is provided in the positioning groove 6, which communicates with the fixing hole 11. When the positioning plate 8 and the through hole 1 are at a certain angle, the fixing rod 2 is not easily removed from the handheld bracket 5. When the positioning plate 8 and the through hole 1 are parallel to each other, the fixing rod 2 can be removed from the handheld bracket 5, thereby allowing the rotating shaft 4 to be removed from the handheld bracket 5.

[0024] The fixing rod 2 includes an upper rod 10 and a lower rod 9. The lower rod 9 is rotatably connected to the rotating shaft 4 and inserted into the lower rod 9. The positioning plate 8 is fixedly connected to the upper rod 10. A spring is fixedly connected to the lower rod 9 and is fixedly connected to the lower rod 9. The spring is located between the lower rod 9 and the upper rod 10. When the rotating shaft 4 is stably installed on the handheld bracket 5, the spring is in a stretched state, and the positioning plate 8 is pressed against the positioning groove 6. Under the action of the spring, the positioning plate 8 is not easily rotated in the positioning groove 6.

[0025] A limiting groove 12 is provided on the lower rod 9, and two limiting grooves 12 are mirror-image arranged on the lower rod 9. A limiting block is fixedly connected to the upper rod 10, and the limiting block is inserted into the limiting groove 12. The limiting block and the limiting groove 12 make the movement of the lower rod 9 in the upper rod 10 more stable, and at the same time make it less likely for the upper rod 10 and the lower rod 9 to separate. The positioning plate 8 is narrow in the middle and wide at both ends, which does not affect the contact stability of the positioning plate 8 in the positioning groove 6, nor does it affect the stability of the fixing rod 2 in the fixing hole 11.

[0026] The positioning groove 6 has a snap-fit ​​groove 13, in which the positioning plate 8 snaps into the snap-fit ​​groove 13. The snap-fit ​​groove 13 increases the stability of the positioning plate 8 in the positioning groove 6, making it less likely for the positioning plate 8 to rotate within the positioning groove 6. The positioning plate 8 has an auxiliary groove 7, with two mirror images of each other. The auxiliary groove 7 facilitates the rotation of the positioning plate 8.

[0027] The implementation principle of this embodiment is as follows: When disassembling the rotating shaft 4, the positioning plate 8 on one side of the handheld frame 5 is pulled outward through the auxiliary groove 7, so that the positioning plate 8 leaves the snap-fit ​​groove 13. Then, the positioning plate 8 is rotated so that the positioning plate 8 is parallel to the through hole 1. The positioning plate 8 is released, the spring contracts, and under the contraction of the spring, the upper rod 10 moves in the direction of the lower rod 9. The positioning plate 8 is carried away from the through hole 1 by the upper rod 10, and the positioning plate 8 is removed from the handheld frame 5. Then, the above operation is repeated to remove the positioning plate 8 on the other side of the handheld frame 5 from the handheld frame 5. In this way, the rotating shaft 4 is completely removed from the handheld frame 5, achieving the effect of conveniently disassembling and replacing the rotating shaft 4 of the wrapping packaging device.
