Description

Technical Field

[0001] This utility model relates to the field of carpet winding technology, and in particular to a winding device for needle-punched carpet fabric. Background Technology

[0002] The production of needle-punched carpets involves a rigorous process. It uses polyester or polypropylene short fibers as the main raw material. These fibers are first carded and then laid out into a uniform mesh structure. During this process, different fibers intertwine and entangle to fix the fabric to the specified specifications. Next, the fabric is needle-punched into a greige fabric. After the greige fabric is formed, it undergoes steps such as back-side gluing, drying, and shaping before finally being rolled and packaged. However, there are certain challenges in the roll-packaging stage. Because needle-punched carpets are large and heavy when rolled, the roll-up rods used to support the roll are difficult to detach smoothly. Furthermore, during the rolling process, due to the lack of an effective support structure, continuous manual support is often required, which not only increases labor costs but also affects production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in smoothly detaching the winding rod used to support the roll, and the need for continuous manual support during the winding process due to the lack of an effective support structure. This invention provides a winding device for needle-punched carpet fabric.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a winding device for needle-punched carpet fabric, comprising a main body, a roller on the outer surface of the main body, a support base on one side of the roller, a support frame fixedly connected to the outer surface of the support base, a winding drum on one side of the support frame, a support assembly inside the winding drum, the support assembly including a movable cylinder, a first insertion hole through both sides of the movable cylinder, a movable slot on the outer surface of the movable cylinder, a support strip attached to the inner wall of the movable slot, and a first spring fixedly connected to the outer surface of the support strip.

[0005] In a preferred embodiment, a movable rod is provided on the outer surface of the support frame, a fixed rod is provided at the top of the movable rod, a rotating shaft is provided at the bottom of the movable rod, a locking block is provided on the outer surface of the fixed rod, and a second spring is fixedly connected to the bottom of the locking block.

[0006] In a preferred embodiment, the outer surface of the fixed rod and the top of the movable rod are movably connected.

[0007] In a preferred embodiment, a connecting plate is fixedly connected to the top of the first spring, and a second insertion hole is provided on one side of the connecting plate.

[0008] In a preferred embodiment, a limiting frame is provided on one side of the support frame, a connector is provided on one side of the support frame, a baffle is provided on one side of the connector, a limiting plate is fixedly connected to one side of the baffle, an insert rod is provided on one side of the limiting plate, and a sliding groove is provided on the outer surface of the support frame.

[0009] In a preferred embodiment, one side of the limiting plate and one side of the limiting frame are fixedly connected, the inner wall of the limiting frame is fitted and connected to the inner wall of the winding drum, and the outer surfaces of the baffle and the limiting plate are movably connected through through holes and the outer surfaces of the insert rod.

[0010] In a preferred embodiment, the top of the support bar is fitted and connected to the inner wall of the winding drum.

[0011] In a preferred embodiment, the outer surface of the support frame and the outer surface of the limiting frame are movably connected.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention features a support base and support frame to support the upper winding structure. A winding drum serves as the primary contact point for winding the needle-punched carpet. Support components control the unfolding and retraction of the two winding drums. The inner walls of both the first and second insertion holes engage with the outer surface of the insertion rod. When the insertion rod passes through the first and second insertion holes, its shape gradually pushes the connecting plates on both sides apart. A first spring releases when the insertion rod disengages, simultaneously relaxing the support bars and the winding drums, facilitating their removal from the carpet roll. A connector controls the insertion rod, and a baffle blocks the limiting plate. A sliding groove allows the limiting plate to move up and down with the carpet roll as it grows larger. These features allow the winding rod to move up and down with the size of the roll, making it easier to detach the winding device from larger carpet rolls. Attached Figure Description

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: As Figures 1-3 As shown, this utility model provides a technical solution: a winding device for needle-punched carpet fabric, including a main body 1, a roller 2 on the outer surface of the main body 1, a support base 3 on one side of the roller 2, a support frame 4 fixedly connected to the outer surface of the support base 3, the outer surface of the support frame 4 being movably connected to the outer surface of the limiting frame 7, a winding drum 5 on one side of the support frame 4, a support assembly 6 inside the winding drum 5, the support assembly 6 including a movable cylinder 61, a first insertion hole 62 penetrating through both sides of the movable cylinder 61, a movable slot 63 on the outer surface of the movable cylinder 61, a support strip 64 fitted to the inner wall of the movable slot 63, and the top of the support strip 64 and the winding drum 64 being fitted to the inner wall of the movable slot 63. The inner wall of the drum 5 is fitted together, and the outer surface of the support bar 64 is fixedly connected to the first spring 65. The top of the first spring 65 is fixedly connected to the connecting plate 66. A second insertion hole 67 is opened on one side of the connecting plate 66. A limit frame 7 is provided on one side of the support frame 4. The inner wall of the limit frame 7 is fitted together with the inner wall of the take-up drum 5. A connector 8 is provided on one side of the support frame 4. A baffle 9 is provided on one side of the connector 8. A limit plate 12 is fixedly connected to one side of the baffle 9. One side of the limit plate 12 is fixedly connected to one side of the limit frame 7. The outer surfaces of the baffle 9 and the limit plate 12 are movably connected to the outer surface of the insertion rod 13 through a through hole. An insertion rod 13 is provided on one side of the limit plate 12. A sliding groove 15 is opened on the outer surface of the support frame 4.

[0022] In this embodiment, a support base 3 and a support frame 4 are provided to support the upper winding structure. A winding drum 5 is provided as the main structure for winding the needle-punched carpet. Two winding drums 5 are symmetrically arranged, but they are not completely fitted together, leaving room for movement within the limiting frame 7. The two winding drums 5 can move up and down. Additionally, the inner walls of the two symmetrically arranged limiting frames 7 are fixed with rotating bearings, allowing the two winding drums 5 to rotate when fully unfolded. A support assembly 6 is provided to control the unfolding and retraction of the two winding drums 5. Symmetrically arranged support bars 64 are used to tightly adhere to the inner walls of the winding drums 5, allowing them to unfold. The inner walls of the first insertion hole 62 and the second insertion hole 67 are engaged with the outer surface of the insertion rod 13. The second insertion hole 67 penetrates the connecting plate 66, and its diameter gradually decreases smoothly from one end to the other, matching the shape of the insertion rod 13. When the insertion rod 13 passes through the first insertion hole 62... When the first spring 65 enters the second insertion hole 67, due to its shape, it will gradually push the connecting plates 66 on both sides to the sides. At the same time, the first spring 65 contracts and the support bar 64 gradually presses against the inner wall of the take-up drum 5. By setting the first spring 65, when the insertion rod 13 is disengaged, the first spring 65 will relax, and the support of the support bar 64 will gradually relax, so that the take-up drum 5 will also relax, making it easier to pull the take-up drum 5 out of the carpet roll. By setting the connector 8, the insertion rod 13 is controlled. The connector 8 and the insertion rod 13 are fixedly connected. By setting the baffle 9, the limiting plate 12 is blocked. By setting the slide groove 15, the limiting plate 12 can move up and down with the size of the roll as the carpet roll gets bigger. In addition, the inner wall of the limiting frame 7 is also provided with a through hole for the insertion rod 13 to fit against the outer surface.

[0023] Example 2: As Figure 4 As shown, a movable rod 10 is provided on the outer surface of the support frame 4, a fixed rod 11 is provided on the top of the movable rod 10, a rotating shaft 14 is provided on the bottom of the movable rod 10, a locking block 16 is provided on the outer surface of the fixed rod 11, a second spring 17 is fixedly connected to the bottom of the locking block 16, and the outer surface of the fixed rod 11 and the top of the movable rod 10 are movably connected.

[0024] In this embodiment, since the carpet roll needs to leave the equipment to detach from the take-up drum 5, a rotating shaft 14 and a moving rod 10 are provided to facilitate rotating the moving rod 10 to one side and removing the take-up drum 5 and the limiting plate 12, etc. In order to fix the moving rod 10 to one side, a fixing rod 11 is provided at the top, passing through the through hole at the top. It is fixed by the locking block 16 and the second spring 17 to the outer surface of the support frame 4 on the other side. The bottom of the locking block 16 is provided with a locking groove. When passing through the support frame 4 on the other side, the locking block 16 will retract into the locking groove.

[0025] Working principle:

[0026] like Figures 1-4As shown, when the take-up drum 5 is about to be used, the insertion rod 13 needs to be inserted through the through holes of the baffle 9, the limiting plate 12, and the limiting frame 7 via the connector 8 into the interior of the take-up drum 5, and then into the support assembly 6. After entering the second insertion hole 67 from the first insertion hole 62, due to the special shape of the insertion rod 13 and the second insertion hole 67, the continuous insertion of the insertion rod 13 will cause the support connecting plate 66 to expand outward, pushing the first spring 65 to contract while pushing the support bars 64 on both sides outward to gradually approach the inner wall of the take-up drum 5 until they are completely pressed together, so that the outer surfaces of both ends of the take-up drum 5 are tightly pressed against the inner wall. In the bearings on the inner wall of the limiting frame 7, as the carpet roll gets bigger, the limiting plate 12 can move up and down in the slide groove 15 according to the size of the roll. After the carpet is rolled up, the locking block 16 is pressed into the locking groove, the second spring 17 retracts, that is, the fixing rod 11 can be pulled away from the support frame 4 and the moving rod 10. Finally, the moving rod 10 is rotated from the rotating shaft 14, so that the entire winding device is disengaged from the slide groove 15. When the insertion rod 13 is disengaged, the first spring 65 will relax, and the support of the support bar 64 will gradually relax, so that the winding drum 5 will also relax, making it easy to pull the winding drum 5 out of the rolled carpet.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
