Description

Technical Field

[0001] The utility model relates to the technical field of bamboo fiber winding devices, and particularly relates to a bamboo fiber winding device for preventing reverse winding. Background Art

[0002] A bamboo fiber winding device is a device for manufacturing bamboo-wound composite materials. It continuously winds processing units such as bamboo fibers, bamboo strips, or bamboo bundles into a specific structure and function composite material. This technology utilizes the axial tensile strength and bending flexibility of bamboo, combines resin as an adhesive, winds it mechanically on a mold through mechanical winding, and then cures the resin to form the final product.

[0003] In the fiber winding device disclosed in the publication number CN612266666U, although in this fiber winding device, a plurality of take-up rollers are fixedly arranged along the circumferential direction of the winding cylinder on the periphery of the winding cylinder, and the fiber is sent from the fiber delivery position through a plurality of take-up rollers and a delivery pin to the winding object, where the fiber delivery position is the position where the fiber leaves the winding cylinder. Based on the above structure of the present utility model, the difference in the fiber delivery length can be reduced, thereby preventing a large change in the tension applied to the fiber.

[0004] However, this fiber winding device has the following disadvantages:

[0005] (1) When winding bamboo fibers onto the surface of the mold, the gaps that may exist between multiple layers of bamboo fibers may cause reverse winding of the bamboo fibers, and there is a lack of a structure to compact the wound bamboo fiber layers to avoid reverse winding and affect the quality of the final product;

[0006] (2) Before winding the bamboo fibers, it is necessary to add resin to the bamboo fibers to facilitate curing after winding. However, if too much resin is added at one time and not used up for a long time, the resin will solidify. Therefore, it is necessary for personnel to frequently add a small amount of resin to ensure that the bamboo fibers can be completely soaked in the resin. Frequent resin addition by personnel greatly increases the work intensity and the complexity of bamboo fiber winding, and the automation efficiency is low. Summary of the Utility Model

[0008] The technical problem solved by the utility model is to provide a bamboo fiber winding device for preventing reverse winding with high practicability, simple operation, and relatively simple structure, which solves the problems of the lack of a structure to compact the wound bamboo fiber layers to avoid reverse winding and affect the quality of the final product, and the problem that frequent resin addition by personnel greatly increases the work intensity and the complexity of bamboo fiber winding, and the automation efficiency is low as mentioned in the above background art.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an anti-backward winding bamboo fiber winding device, including a winding device 1, a base 2 is fixedly connected to the bottom end of the winding device 1, a resin tank 3 is fixedly connected to one side of the top surface of the base 2, a device plate 4 is fixedly connected to the top surface of the resin tank 3, a feeding assembly 5 is fixedly connected to the top surface of the device plate 4, and an anti-backward winding assembly 6 is fixedly connected to the other side of the top surface of the base 2.

[0028] Please refer to Figure 2 , a slider is fixedly connected to the side surface of the upper side plate 613, a sliding groove is opened on the side surface of the lower side plate 612, the inner diameter of the sliding groove fits with the slider, and the slider is slidably connected to the inside of the sliding groove; when the upper side plate 613 slides on the inner side wall of the lower side plate 612, the slider fixed to the side surface of the upper side plate 613 moves synchronously inside the sliding groove opened on the side surface of the lower side plate 612 to limit the sliding of the upper side plate 613 and avoid lateral shaking, which affects the compaction effect of the upper pressure roller 64.

[0029] Please refer to Figure 4 , a sleeve hole matching the solenoid valve 54 is opened on the top surface of the device plate 4, a liquid level sensor 7 is fixedly connected to the bottom surface of the device plate 4, and the solenoid valve 54 is electrically connected to the surface of the liquid level sensor 7; the liquid level sensor 7 can monitor the remaining resin in the resin tank 3 in real time, automatically add or stop the resin, and reduce the work complexity.

[0030] In the present utility model, the working steps of the device are as follows:

[0031] First, place the opened resin bucket 55 with its outlet facing down inside the fixed cylinder 51. The resin inside the resin bucket 55 will flow into the inside of the conical funnel 53. Since the electromagnetic valve 54 is not opened, it will remain inside the conical funnel 53. When the liquid level sensor 7 fixed to the bottom surface of the equipment board 4 detects that the resin remaining amount inside the resin tank 3 is low, the electromagnetic valve 54 controlled by it is opened, and the resin flows into the inside of the resin tank 3 through the electromagnetic valve 54. When the resin remaining amount inside the resin tank 3 is sufficient, the liquid level sensor 7 will control the electromagnetic valve 54 to close, so that the resin inside the resin tank 3 will not continue to increase and cause excessive storage and curing. Furthermore, when the winding device 1 winds the bamboo fiber, the winding device 1 will press down the pressure roller 64. The pressure roller 64 squeezes the top plate 614 through the bracket 63. When the top plate 614 moves downward, it will compress the spring 615. When the spring 615 is compressed again, it will release the resilience, and push the pressure roller 64 rotatably connected to the side of the bracket 63 to squeeze the surface of the winding device 1, and compact the bamboo fiber layer wound on its surface. Finally, as more and more bamboo fiber is wound on the surface of the winding device 1, its own diameter will also increase. The driving motor 621 drives the lead screw 622 fixed to its output end to rotate, so that the adjusting plate 623 threadedly connected to the surface of the lead screw 622 moves downward and compresses the spring 615, shortening the rebound stroke of the spring 615 and making the resilience greater, so as to compact a thicker bamboo fiber layer to avoid the occurrence of reverse winding.
