Description

Technical Field

[0001] This utility model relates to the technical field of camouflage net weaving equipment, and in particular to a large-size camouflage net weaving auxiliary rotating roller. Background Technology

[0002] Camouflage nets are an important camouflage and concealment tool used in film and television set construction, theme park environment decoration, partial camouflage in home decoration, atmosphere creation in military exhibitions, background setup for photography, and concealment and sunshade for birdwatching. They serve to beautify, conceal, or camouflage. When camouflage nets are woven, rollers are usually needed for auxiliary transport. Existing camouflage net weaving rollers can basically meet the needs of daily use, but there are still some shortcomings that need to be improved.

[0003] Most existing camouflage net weaving rollers on the market are of fixed size. Most rollers adopt a fixed size design and are only suitable for weaving operations of camouflage nets of specific specifications. When the production task involves camouflage nets of different sizes, special rollers need to be customized, which not only greatly increases the production cost and time cost, but also restricts the flexibility and efficiency of production. To address this issue, we propose a large-size camouflage net weaving auxiliary rotating roller to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a large-size camouflage net weaving auxiliary rotating roller to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-size camouflage net weaving auxiliary rotating roller, including a base, with rotating seats installed on both sides of the base, and a first roller arranged between the two sets of rotating seats. Both sides of the first roller are rotatably connected to the rotating seats via rotating rods. Multiple connecting plates are installed at equal intervals on the first roller, and multiple sets of locking pins are installed at equal intervals on the outer walls of the connecting plates. A driving assembly is provided at the right end of the base, and a movable base is provided at the left end of the base. A second roller is installed on the movable base, with connecting rods installed on both the front and rear sides of the left end of the movable base. Connecting cylinders are installed on both the front and rear sides of the left end of the base and the movable base, and locking assemblies are installed at the ends of the connecting cylinders. Turntables are installed on the rotating rods at the left ends of both the first and second rollers, with multiple sets of slots evenly spaced on the turntables. A driven plate is installed on the rotating rod at the right end of the second roller, with multiple sets of locking pins evenly spaced at the end of the driven plate away from the second roller. The multiple sets of locking pins can be inserted into the slots on the turntable.

[0006] As an improved technical solution, the drive assembly includes a base plate mounted on the right side of the base, a drive motor mounted on the base plate, a second pulley mounted on the output end of the drive motor, a first pulley mounted on the rotating rod at the right end of the first roller, and a transmission belt mounted between the first pulley and the second pulley.

[0007] As an improved technical solution, the locking assembly includes a sleeve fixed to the right end of the connecting cylinder, a guide slide rod fixed inside the sleeve, a movable block provided outside the guide slide rod, a positioning post installed on the outer wall of the left end of the movable block, a pull handle fixed to the front end of the positioning post, positioning holes opened at the right ends of both sets of connecting rods, the positioning post can be inserted into the positioning holes on the connecting rod, and a return spring is wound around the outside of the guide slide rod.

[0008] As an improved technical solution, the diameter of the positioning post is the same as the inner diameter of the positioning hole on the connecting rod.

[0009] As an improved technical solution, the movable block is provided with a sliding hole that matches the guide slide rod, and the movable block and the guide slide rod are slidably connected through the sliding hole.

[0010] As an improved technical solution, the two ends of the return spring are respectively connected to the outer wall of the movable block and the inner wall of the sleeve, and the movable block is elastically connected to the inner wall of the sleeve through the return spring.

[0011] As an improved technical solution, the input terminal of the drive motor is electrically connected to an external controller via a wire.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] I. This utility model features a turntable mounted on the rotating rod at the left end of the first roller. This allows multiple sets of locking pins on the driven disc on the right side of the second roller to be inserted into the slots on the turntable, ensuring complete engagement between the driven disc and the turntable. This enables the second and first rollers to rotate synchronously. Furthermore, connecting cylinders are installed at both the front and rear ends of the base and the left side of the rotating base. Two sets of connecting rods on the rotating base are inserted into the two sets of connecting cylinders to complete the initial connection. This allows the device to add a corresponding number of rollers according to the actual size of the camouflage net, thus adapting to the weaving needs of different sized camouflage nets, significantly reducing production costs and ensuring production efficiency.

[0014] II. This utility model has a drive motor installed at the right end of the base, which drives the second pulley to rotate, and then the transmission belt drives the first pulley and the first roller to rotate. This allows the drive motor to accurately control the speed of the first roller. The overall structure is simple and reliable, and is easy to maintain.

[0015] III. This utility model has a positioning post that can move back and forth installed on the outside of the connecting cylinder. When the movable base drives the two sets of connecting rods to be inserted into the two sets of connecting cylinders, the two sets of return springs can release their elasticity and push the two sets of movable blocks to move in opposite directions. The two sets of movable blocks drive the two sets of positioning posts to be inserted into the two sets of positioning holes on the two sets of connecting rods, thus quickly locking the two sets of connecting rods and improving the convenience of roller installation.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, the large-size camouflage net weaving auxiliary rotating roller includes a base 1, with rotating seats 2 installed on both sides of the base 1. A first roller 3 is arranged between the two sets of rotating seats 2. Both sides of the first roller 3 are rotatably connected to the rotating seats 2 through rotating rods 4. Multiple connecting plates 5 are installed at equal intervals on the first roller 3, and multiple sets of pins 6 are installed at equal intervals on the outer wall of the connecting plates 5. A driving assembly is provided at the right end of the base 1, and a movable base 12 is provided at the left end of the base 1. A second roller 13 is installed on the movable base 12. Connecting rods 18 are installed on both the front and rear sides. Connecting cylinders 20 are installed on both the front and rear sides of the left end of the base 1 and the movable base 12. Locking components are installed at the ends of the connecting cylinders 20. Turntables 16 are installed on the rotating rods 4 at the left ends of the first roller 3 and the second roller 13. Multiple sets of slots 17 are equally spaced on the turntables 16. A driven plate 14 is installed on the rotating rod 4 at the right end of the second roller 13. Multiple sets of locking pins 15 are equally spaced on the end of the driven plate 14 away from the second roller 13. The multiple sets of locking pins 15 can be inserted into the slots 17 on the turntable 16.

[0023] A turntable 16 is installed on the rotating rod 4 at the left end of the first roller 3, allowing multiple sets of locking pins 15 on the driven plate 14 on the right side of the second roller 13 to be inserted into the slots 17 on the turntable 16, so that the driven plate 14 and the turntable 16 are fully engaged, allowing the second roller 13 and the first roller 3 to rotate synchronously. Then, by installing connecting cylinders 20 at both the front and rear ends of the left side of the base 1 and the rotating base 2, two sets of connecting rods 18 on the rotating base 2 are inserted into the two sets of connecting cylinders 20 to complete the initial connection. This allows the device to add a corresponding number of rollers according to the actual size of the camouflage net, thereby adapting to the weaving needs of different sized camouflage nets, greatly reducing production costs and ensuring production efficiency.

[0024] In other embodiments, the drive assembly includes a base plate 8 mounted on the right side of the base 1, a drive motor 9 mounted on the base plate 8, a second pulley 10 mounted on the output end of the drive motor 9, a first pulley 7 mounted on the rotating rod 4 at the right end of the first roller 3, and a transmission belt 11 mounted between the first pulley 7 and the second pulley 10.

[0025] By installing a drive motor 9 at the right end of the base 1, the drive motor 9 can drive the pulley 10 to rotate, and then the transmission belt 11 can drive the pulley 7 and the first roller 3 to rotate. Thus, the drive motor 9 can accurately control the speed of the first roller 3, and the overall structure is simple and reliable, making it easy to maintain later.

[0026] In other embodiments, the locking assembly includes a sleeve 21 fixed to the right end of the connecting cylinder 20, a guide slide rod 22 fixed inside the sleeve 21, a movable block 23 provided outside the guide slide rod 22, a positioning post 24 installed on the outer wall of the left end of the movable block 23, a pull handle 25 fixed to the front end of the positioning post 24, positioning holes 19 are opened at the right ends of both sets of connecting rods 18, the positioning post 24 can be inserted into the positioning holes 19 on the connecting rods 18, and a return spring 26 is wound around the outside of the guide slide rod 22;

[0027] When it is necessary to insert the connecting rod 18 into the connecting cylinder 20, the two sets of handles 25 can be pulled outwards, causing the two sets of positioning pins 24 to drive the two sets of movable blocks 23 to move in opposite directions along the guide slide bar 22, and causing the two sets of movable blocks 23 to press the return spring 26. When the two sets of positioning pins 24 leave the interior of the connecting cylinder 20, the movable base 12 can then drive the two sets of connecting rods 18 to be inserted into the interior of the two sets of connecting cylinders 20. When the two sets of connecting rods 18 move to the limit inside the connecting cylinder 20, the pulling force on the two sets of handles 25 can be released, allowing the two sets of return springs 26 to release their elasticity and push the two sets of movable blocks 23 to move in opposite directions, causing the two sets of movable blocks 23 to drive the two sets of positioning pins 24 to be inserted into the two sets of positioning holes 19 on the two sets of connecting rods 18, quickly completing the locking of the two sets of connecting rods 18, thereby improving the convenience of roller installation.

[0028] In other embodiments, the diameter of the positioning post 24 is the same as the inner diameter of the positioning hole 19 on the connecting rod 18;

[0029] With this design, when the positioning pin 24 is inserted into the positioning hole 19 on the connecting rod 18, it can effectively prevent the connecting rod 18 from shifting, thus ensuring the stability of the equipment during use.

[0030] In other embodiments, the movable block 23 is provided with a sliding hole that matches the guide slide rod 22, and the movable block 23 and the guide slide rod 22 are slidably connected through the sliding hole;

[0031] This design ensures the stability of the linear motion of the movable block 23 as it moves along the surface of the guide slide bar 22, and ensures that the positioning pin 24 can be smoothly inserted into the positioning hole 19 on the connecting rod 18.

[0032] In other embodiments, the two ends of the return spring 26 are respectively connected to the outer wall of the movable block 23 and the inner wall of the sleeve 21, and the movable block 23 is elastically connected to the inner wall of the sleeve 21 through the return spring 26;

[0033] This design allows the return spring 26 to continuously apply a backward elastic force to the movable block 23, enabling the movable block 23 to drive the positioning pin 24 to quickly reset, allowing the positioning pin 24 to insert into the positioning hole 19 on the connecting rod 18.

[0034] In other embodiments, the input terminal of the drive motor 9 is electrically connected to an external controller via a wire;

[0035] This design allows an external controller to precisely control the speed of the drive motor 9, thereby adapting to different weaving process requirements.

[0036] This utility model provides a large-size camouflage net weaving auxiliary rotating roller, the specific working principle of which is as follows:

[0037] When the second roller 13 needs to be installed, the two sets of handles 25 can be pulled outwards, causing the two sets of positioning pins 24 to drive the two sets of movable blocks 23 to move in opposite directions along the guide slide rod 22. When the two sets of positioning pins 24 leave the interior of the connecting cylinder 20, the movable base 12 can then drive the two sets of connecting rods 18 to insert into the interior of the two sets of connecting cylinders 20. When the two sets of connecting rods 18 move to their limit inside the connecting cylinder 20, the pulling force on the two sets of handles 25 can be released, allowing the two sets of return springs 26 to release their elasticity and push the two sets of movable blocks 23 to move in opposite directions, allowing the two sets of movable blocks 23 to move in opposite directions. Block 23 drives two sets of positioning pins 24 to insert into the two sets of positioning holes 19 on the two sets of connecting rods 18, and allows the locking pins 15 on the driven plate 14 at the right end of the second roller 13 to insert into the slots 17 on the turntable 16 at the left end of the first roller 3, so that the two rollers form a mechanical linkage. Then the controller starts the drive motor 9, which drives the first roller 3 to rotate through the second pulley 10, the transmission belt 11 and the first pulley 7, and makes the second roller 13 rotate synchronously. Then the edge of the camouflage net is fixed to the pins 6 on the connecting plate 5, and uniform weaving is achieved with the rotation of the two rollers.

[0038] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
