Description

Technical Field

[0001] This utility model relates to the technical field of winding devices, specifically a winding device for camouflage nets. Background Technology

[0002] Camouflage nets are camouflage and concealment equipment used to cover military targets. Their origins can be traced back to the practice of covering weapons with fishing nets during World War I. The main material is PVC plastic monofilament woven fabric, which has the ability to counter visible light, infrared radiation, and radar detection. It is widely used in military equipment and civilian fields. During the production process, camouflage nets require a winding device to achieve standardized production, facilitate subsequent processing, and meet storage and transportation needs.

[0003] However, existing camouflage net winding devices do not keep the starting edge of the camouflage net perfectly parallel to the winding roller when winding it. During subsequent winding, due to the starting point deviation, local stacking occurs, forming large-area wrinkles. The net body in a wrinkled state for a long time will generate stress concentration at the creases, which will not only shorten the service life of the product, but also affect the winding effect. Summary of the Invention

[0004] This utility model provides a winding device for camouflage nets, which has the function of positioning and flattening camouflage nets of different widths while winding them up. This not only extends the service life of the product but also improves the winding effect, solving the problems mentioned in the background art.

[0023] 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. Example 1

[0024] This embodiment aims to facilitate a solution to the problem of how to avoid wrinkles in camouflage netting during the winding process. Please refer to [link to relevant documentation]. Figures 1-4 A camouflage net winding device includes a base plate 1. A gantry frame 2 is fixedly connected to one side of the top of the base plate 1. A fixing frame 3 is fixedly connected to one side of the gantry frame 2. Two support frames 4 are provided on the side of the fixing frame 3 away from the gantry frame 2. Each support frame 4 is fixedly connected to the base plate 1. A winding roller 5 is provided between the two support frames 4. The top of each support frame 4 is provided with a U-shaped groove adapted to the winding roller 5. A camouflage net body 6 is adhered to the surface of the winding roller 5. A winding element 7 is provided at one end of the winding roller 5, which can control the winding roller 5. The camouflage net body 6 is wound up by rotating at a constant speed. The gantry frame 2 is equipped with a flattening mechanism 8. The flattening mechanism 8 can not only position the camouflage net body 6 of different widths during the winding process, but also flatten the camouflage net body 6. The fixing frame 3 is equipped with a cutting mechanism 9. The cutting mechanism 9 can cut the camouflage net body 6. The top of the two support frames 4 is equipped with a replacement mechanism 10. The replacement mechanism 10 makes it convenient for users to replace the winding roller 5 of the wound camouflage net body 6.

[0025] The take-up component 7 includes a first gear 71 fixedly installed at one end of the take-up roller 5, a second gear 72 meshing at the bottom of the first gear 71, the diameter of the second gear 72 being larger than that of the first gear 71, a motor frame 73 fixedly connected to the support frame 4 near the second gear 72, a motor 74 fixedly connected to the side of the motor frame 73 away from the second gear 72, and the output end of the second gear 72 being fixedly connected to the motor 74.

[0026] The flattening mechanism 8 includes a concave roller 81 rotatably mounted inside the gantry frame 2. A matching convex roller 82 is rotatably mounted on the gantry frame 2 near the concave roller 81. As the camouflage net body 6 is pulled along the surface of the convex roller 82, the surface of the convex roller 82 is arc-shaped, higher in the middle and lower at both ends. This causes the camouflage net body 6 to continuously extend towards both sides of the convex roller 82 under tension, thus flattening the camouflage net body 6. Four first positioning rollers 83 are provided at the bottom of the convex roller 82, and each of the first positioning rollers 83 has a second positioning roller 84 at its bottom. Both the first positioning roller 83 and the second positioning roller 84 are rotatably connected to the gantry 2. The end of the camouflage net body 6 away from the winding roller 5 is coupled to the first positioning roller 83, the second positioning roller 84, the convex roller 82, and the concave roller 81, which can keep the camouflage net body 6 on both sides of the convex roller 82 perpendicular, thereby increasing the contact area between the camouflage net body 6 and the convex roller 82. An adjusting member 85 is provided between the first positioning roller 83 and the second positioning roller 84, which can be adjusted according to the width of the camouflage net body 6, thereby positioning the camouflage net body 6.

[0027] The adjusting component 85 includes a bidirectional screw 851 rotatably installed inside the gantry frame 2. A knob is fixedly installed at one end of the bidirectional screw 851. Adjusting blocks 852 are threadedly connected to the outer surfaces of both ends of the bidirectional screw 851. The bidirectional screw 851 can adjust the distance between the two adjusting blocks 852. Slide rods 853 are provided on both sides of the bidirectional screw 851. The slide rods 853 can limit the adjustment blocks 852, so that the two adjusting blocks 852 can slide flexibly horizontally. The slide rods 853 are fixedly connected to the gantry frame 2, and the adjusting blocks 852 are slidably connected to the slide rods 853.

[0028] In this embodiment: the drive motor 74 drives the second gear 72, which in turn controls the winding roller 5 to rotate between the two support frames 4 via the first gear 71, thereby continuously pulling the camouflage net body 6 to wind it up. Under the action of tension, the camouflage net body 6 extends towards both sides of the convex roller 82 due to the arc-shaped surface of the convex roller 82, which is higher in the middle and lower at both ends, thus flattening the camouflage net body 6. The user can also control the bidirectional screw 851 to rotate according to the width of the camouflage net body 6 via a knob. While the bidirectional screw 851 rotates, it drives the adjusting block 852. The adjusting block 852 slides through the cooperation of the slide rod 853, so that the two adjusting blocks 852 move to the edges on both sides of the camouflage net body 6, limiting the camouflage net body 6 and keeping it at the center of the convex roller 82. Example 2

[0029] This embodiment aims to facilitate the replacement of the winding roller 5 after the camouflage net has been wound up by the user. This embodiment is an improvement on Embodiment 1. For details, please refer to [link / reference]. Figures 1-7 The cutting mechanism 9 includes a blade 91 fixedly installed inside the fixed frame 3. Two third positioning rollers 92 are provided on both sides of the blade 91. The third positioning rollers 92 are coupled to the camouflage net body 6 and rotatably connected to the fixed frame 3. The third positioning rollers 92 can position the camouflage net body 6 so that the camouflage net body 6 fits against the upper surface of the blade 91. A cutting blade 93 is provided on the top of the blade 91. Electric push rods 94 are fixedly installed on both sides of the top of the fixed frame 3. The telescopic ends of the two electric push rods 94 are fixedly connected to the cutting blade 93. The telescopic movement of the electric push rods 94 can control the vertical lifting and lowering movement of the cutting blade 93.

[0030] The replacement mechanism 10 includes two rotating plates 101 rotatably mounted on the top of the support frame 4. The bottom of each rotating plate 101 is fixedly connected to a limiting plate 102. The limiting plate 102 and the support frame 4 near the take-up roller 5 are each embedded with three balls 103. This not only limits the take-up roller 5 inside the support frame 4, but also allows the take-up roller 5 to rotate flexibly. Each of the two support frames 4 is provided with a locking knob 104 on one side. One end of the locking knob 104 passes through the support frame 4 and extends into the interior of the rotating plate 101. The locking knob 104 is threadedly connected to the rotating plate 101. The locking knob 104 can lock the rotating plate 101 when it is in a horizontal state. Each support frame 4 near the locking knob 104 is provided with a matching slot 105.

[0031] A control box 11 with a programmable controller is fixedly installed on one side of the mounting bracket 3, which facilitates users to set instructions and control the operation of the device.

[0032] The bottom four corners of the base plate 1 are all fixedly installed with casters 12 with braking function, which makes it convenient for users to move and fix the device.

[0033] In this embodiment: after winding is completed, the electric push rod 94 pushes the cutting blade 93 to move vertically downward, and then cooperates with the blade plate 91 to cut the camouflage net body 6. Then, the two locking knobs 104 are rotated to separate the locking knobs 104 from the support frame 4. Then, the rotating plate 101 is controlled to rotate. While the rotating plate 101 is rotating, it drives the limiting plate 102 to separate from the winding roller 5, so that the winding roller 5 can be replaced.
