Description

Technical Field

[0001] This utility model relates to the field of dustproof net production technology, and in particular to a cutting device for dustproof net production. Background Technology

[0002] Dust control nets, also known as "windbreak and dust suppression nets" or "windbreak walls," are environmental protection projects used to control dust pollution in open-air material yards. They are widely used in bulk cargo ports, fuel storage yards of thermal power plants, raw material and fuel storage yards of steel enterprises, raw material and fuel storage yards of chemical enterprises, coal storage yards of coal mines, etc. Dust control nets utilize aerodynamic principles and are processed into windbreak and dust suppression walls with specific geometric shapes, opening ratios, and combinations of different hole shapes based on the results of wind tunnel experiments on the implementation site. This causes the circulating air (strong wind) to pass through the wall from the outside, creating upward and downward interfering airflows on the inner side of the wall, achieving the effect of strong wind on the outside and weak wind on the inside, or even a light wind on the outside and no wind on the inside, thereby preventing dust from flying.

[0003] In the existing technology, dustproof nets are cut using a cutting device during the production and processing. Generally, the dustproof net is wound on a take-up roller to reach the required length and then cut. It is inconvenient to adjust the width of the dustproof net during cutting. Therefore, a cutting device for dustproof net production is proposed. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution for a cutting device for dustproof net production, including a device platform 1 and placement plates 2 installed at the four corners of the top of the device platform 1. Two placement plates 2 at one end are used to place the wound dustproof net, and two other placement plates 2 at the other end are used to place the dustproof net after being wound and cut by a take-up roller. A strip plate 12 is installed on one side of each of the two placement plates 2. A bidirectional lead screw 13 is rotatably connected between the two strip plates 12. Connecting blocks 14 are symmetrically arranged on the bidirectional lead screw 13. A concave frame 15 is installed at the top of each of the two connecting blocks 14. A first screw 21 is threadedly connected to the top of one end of each of the two concave frames 15. A first cutting blade 22 is installed at the bottom of each first screw 21. A cutting groove is provided inside the bottom of each of the two concave frames 15. Two connecting blocks 14 are threadedly connected to the bidirectional lead screw 13. A rotating rod is installed at one end of the bidirectional lead screw 13. Rotating the rotating rod drives the bidirectional lead screw 13 to rotate. When the bidirectional lead screw 13 rotates, the two connecting blocks 14 move on the outside. When the connecting blocks 14 move, they drive the concave frame 15 to move together. The threads on the bidirectional lead screw 13 are arranged opposite to each other. Therefore, when the bidirectional lead screw 13 rotates, the connecting blocks 14 on the outside can move closer to each other or further away from each other to adjust the distance between the concave frames 15 and cut the width of the dustproof net. The two sides of the rolled dustproof net pass through the two concave frames 15. Rotating the first screw 21 causes the first screw 21 to move downward on the concave frame 15, so that the first cutting blade 22 abuts against the dustproof net for cutting.

[0021] Each placement plate 2 has a placement cylinder 3 rotatably mounted near its top. One end of each placement cylinder 3 is threadedly connected to a second screw 11. One end of the second screw 11 extends into the interior of the placement cylinder 3 and is rotatably connected to a limiting cylinder 23. The limiting cylinder 23 is slidably positioned inside the placement cylinder 3. Each placement cylinder 3 has a placement groove inside. Fixed plates 4 are symmetrically mounted on the device platform 1. Multiple guide rollers 5 are installed between two fixed plates 4. Connecting rods 6 are rotatably connected to the outer sides of both placement plates 2. A connecting pulley 8 is drively connected between the two connecting rods 6. A drive gear 7 is mounted on each connecting rod 6. A drive motor 9 is mounted on one placement plate 2. The power output end of the motor 9 is fixedly connected to a connecting rod 6. Both placement cylinders 3 are equipped with driven gears 10. The two driving gears 7 mesh with the two driven gears 10 respectively. When the motor 9 is powered on, it drives the connecting rod 6 to rotate. The connecting pulley 8 enables the two connecting rods 6 to rotate synchronously. The two driving gears 7 mesh with the driven gears 10 to drive the two placement cylinders 3 to rotate, which facilitates the release of the wound dustproof net and the winding of the cut dustproof net on the take-up roller. When the second screw 11 is rotated, the limiting cylinder 23 moves inside the placement cylinder 3 and abuts against the two ends of the take-up roller and the take-up roller for winding the dustproof net, clamping the take-up roller between the two placement cylinders 3.

[0022] A strip frame 16 is installed near the top between the two fixed plates 4. A pressing rod 17 is slidably connected to the top of the strip frame 16. A second cutting blade 20 is installed at the bottom of the pressing rod 17 inside the strip frame 16. A sliding groove adapted to the pressing rod 17 is provided at the top of the strip frame 16. A sliding plate 19 is provided on the pressing rod 17. A spring 18 is sleeved on the pressing rod 17, and a baffle is installed at the top of the pressing rod 17. The spring 18 is located between the sliding plate 19 and the... Between the baffles, the slide plate 19 is located at the top of the strip frame 16. The dustproof net passes through the guide rollers 5 in sequence and is stretched in a triangular shape. It first passes downward through one guide roller 5 and then upward through the highest guide roller 5 for easy cutting. The pressing rod 17 is pressed down and slides downward inside the slide plate 19, driving the second cutting blade 20 to move downward and abut against the dustproof net on the highest guide roller 5. The pressing rod 17 is pulled and slides on the strip frame 16 to cut the dustproof net.

[0023] The working principle of this utility model is as follows: Two placement plates 2 at one end are used to place the wound dustproof net, and two other placement plates 2 at the other end are used to place the dustproof net after being wound and cut by the take-up roller. When the second screw 11 is rotated, the limiting cylinder 23 moves inside the placement cylinder 3 and abuts against the two ends of the take-up roller and the dustproof net take-up roller, clamping the take-up roller between the two placement cylinders 3. Rotating the rotating rod drives the bidirectional screw 13 to rotate. When the bidirectional screw 13 rotates, the two connecting blocks 14 move on the outside. Rotating the rotating rod in different directions drives the bidirectional screw 13 to rotate, adjusting the distance between the concave frames 15 and cutting the width of the dustproof net. The wound dustproof net passes through the two concave frames 15 on both sides. Rotating the first screw 21 causes the first screw 21 to move downward on the concave frame 15, so that the first cutting blade 22 makes contact with the dustproof net. The dustproof netting is cut by contacting the guide rollers 5 in sequence, forming a triangular tension. It first passes downward through one guide roller 5, then upward through the highest guide roller 5, and then downward through another guide roller 5 to be wound with the take-up roller, thus tightening the dustproof netting for easy cutting. The pressing rod 17 is pressed down, and the pressing rod 17 slides downward within the slide plate 19, driving the second cutting blade 20 to move downward and contact the dustproof netting on the highest guide roller 5. The pressing rod 17 is pulled, and it slides on the strip frame 16 to cut the dustproof netting. The drive motor 9 is powered on and drives a connecting rod 6 to rotate. The connecting pulley 8 enables the two connecting rods 6 to rotate synchronously. The two drive gears 7 mesh with the driven gear 10 to drive the two placement cylinders 3 to rotate, facilitating the release of the wound dustproof netting and the winding of the cut dustproof netting onto the take-up roller.

[0024] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
