Technical Field
[0001] This utility model belongs to the field of dustproof net processing technology, specifically a dustproof net cutting device for building construction. Background Technology
[0002] Dust control nets, also known as "windbreak and dust suppression nets" or "windbreak walls," are an environmental protection project 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, and so on. At various construction sites, dust control nets are laid on the site to prevent dust from spreading. According to the specifications of the construction site, the dust control nets are cut into different sizes using cutting devices.
[0003] Existing dust control netting cutting devices for construction use often result in skewed cuts due to unevenness of the netting itself or movement caused by the cutting blade. This leads to waste of the netting and the device only supports one width of netting roll. Different widths of netting rolls cannot be securely fixed to the machine, causing skewed cuts. Furthermore, existing machines cannot be used to fix netting rolls of different widths, making them extremely inconvenient to use. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a dustproof net cutting device for construction, which solves the problem that when fixing dustproof net rolls of different widths on this machine, the dustproof nets are not fixed tightly and are easy to become crooked, and existing machines cannot fix dustproof net rolls of different widths.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof net cutting device for construction, comprising a cutting body, a servo motor installed inside the cutting body, a rotating column fixedly connected to the output end of the servo motor, a rotating disk fixedly connected to one end of the rotating column, a rotating groove formed on one side of the rotating disk, a movable ball rod slidably connected within the rotating groove, a ball rod connecting block connected to one end of the movable ball rod via a pin, and a push spring fixedly connected to one side of the ball rod connecting block;
[0006] The other end of the push spring is fixedly connected to the inside of the cutting body. One end of the ball rod connecting block is fixedly connected to a rotating rod block. A fixed main rod is sleeved inside the rotating rod block. Both ends of the fixed main rod are fixedly connected to the inside of the cutting body. A pulling connecting block is provided on the outer arc surface of the rotating rod block. A tension block is connected to one side of the pulling connecting block through a pin. A spring rod is fixedly connected to one end of the tension block. A connecting rod is fixedly connected to one end of the spring rod. A base is fixedly connected to the bottom of the cutting body. A roll body is fixedly connected to the top of the base. A rotating fixed shaft is provided on one side of the roll body.
[0007] As a further embodiment of this utility model: a crossbar is fixedly connected to one end of the connecting rod, and tension rods are fixedly connected to both sides of the crossbar.
[0008] As a further embodiment of this utility model: the outer arc surface of the tension rod is movably connected to a fixing block, and the surfaces of the two fixing blocks are fixedly connected to the same side of the cutting body.
[0009] As a further embodiment of this utility model: a return spring is sleeved on the outer arc surface of the tension rod, and a flattening block is fixedly connected to one end of the return spring.
[0010] As a further embodiment of this utility model: a cutting groove is fixedly connected to the bottom end of the flattening block, a rotary motor is provided in the cutting groove, a threaded rod is fixedly connected to the output end of the rotary motor, and a cutting blade is movably connected to the external thread of the threaded rod.
[0011] As a further embodiment of this utility model: the number of the rotating fixed shafts is two, and a rotating shaft is fixedly connected to one side of each of the two rotating fixed shafts.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This dustproof netting cutting device for construction uses a servo motor, rotating column, rotating disk, rotating groove, moving ball rod, ball rod connecting block, rotating rod block, pulling connecting block, and fixed main rod. First, the servo motor is started, driving the rotating disk through its output. As the rotating disk rotates, the moving ball rod moves within the rotating groove. When it reaches the inner wall of the groove, the moving ball rod moves inward, pulling the ball rod connecting block, rotating rod block, and pulling connecting block backward. This pulls the tensioning block backward and simultaneously moves the tensioning rod, causing the flattening block to come into contact, thus clamping and fixing the dustproof netting. In the relaxed state, the dustproof netting can be smoothed to prevent wrinkles that could cause cutting deviations, skewed cuts, and reduced waste.
[0014] 2. This construction dustproof netting cutting device consists of a rotary motor, a threaded rod, cutting blades, a base, a roll body, a rotating fixing shaft, and a rotating shaft. First, a section of dustproof netting is rolled into the rotating shaft. Then, the rotating fixing shafts on both sides are activated, causing the dustproof netting to shrink. The flattening block on top smooths the netting. When cutting, the flattening block presses the netting in place. The rotary motor then rotates the threaded rod, which in turn moves the cutting blades to cut the dustproof netting. This device can handle dustproof netting rolls of different widths, providing a more secure hold and preventing the netting from warping. Attached Figure Description

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a dustproof net cutting device for construction, including a cutting body 1, a servo motor 2 is installed inside the cutting body 1, a rotating column 3 is fixedly connected to the output end of the servo motor 2, a rotating disk 4 is fixedly connected to one end of the rotating column 3, a rotating groove 5 is opened on one side of the rotating disk 4, a movable ball rod 6 is slidably connected in the rotating groove 5, a ball rod connecting block 7 is connected to one end of the movable ball rod 6 through a pin, a push spring 27 is fixedly connected to one side of the ball rod connecting block 7, a crossbar 14 is fixedly connected to one end of the connecting rod 13, and tension rods 15 are fixedly connected to both sides of the crossbar 14. Through the setting of the crossbar 14 and the tension rods 15, the crossbar 14 drives the tension rods 15 on both sides to move together, so that the tension rods 15 move together, which facilitates the flattening of both ends of the flattening block 18 at the same time;
[0022] The outer arc surface of the tension rod 15 is movably connected to a fixing block 16. The surfaces of the two fixing blocks 16 are fixedly connected to one side of the same cutting body 1. Through the setting of the fixing blocks 16, the tension rod 15 moves in the fixing blocks 16 to prevent the tension rod 15 from shifting and causing deviation in flattening.
[0023] A return spring 17 is sleeved on the outer arc surface of the tension rod 15. One end of the return spring 17 is fixedly connected to a flattening block 18. After flattening, the return spring 17 returns to its original position to prevent the dustproof net from being damaged due to prolonged flattening.
[0024] The other end of the push spring 27 is fixedly connected to the inside of the cutting body 1. One end of the ball rod connecting block 7 is fixedly connected to the rotating rod block 8. The rotating rod block 8 is fitted with a fixed main rod 10. Both ends of the fixed main rod 10 are fixedly connected to the inside of the cutting body 1. The bottom end of the flattening block 18 is fixedly connected to the cutting groove 19. The cutting groove 19 is equipped with a rotary motor 20. The output end of the rotary motor 20 is fixedly connected to the threaded rod 21. The external thread of the threaded rod 21 is movably connected to the cutting blade 22. Through the arrangement of the cutting groove 19, the rotary motor 20 and the cutting blade 22, when the flattening block 18 fixes the dustproof net, the rotary motor 20 can be started to drive the threaded rod 21 and the cutting blade 22 to cut, so that the dustproof net is cut when it is in the most stable position, and the cutting is prevented from being skewed.
[0025] A pulling connecting block 9 is provided on the outer arc surface of the rotating rod block 8. A tension block 11 is connected to one side of the pulling connecting block 9 via a pin. A spring rod 12 is fixedly connected to one end of the tension block 11. A connecting rod 13 is fixedly connected to one end of the spring rod 12. A base 23 is fixedly connected to the bottom end of the cutting body 1. A roll body 24 is fixedly connected to the top end of the base 23. A rotating fixing shaft 25 is provided on one side of the roll body 24. There are two rotating fixing shafts 25. A rotating shaft 26 is fixedly connected to one side of the two rotating fixing shafts 25. By setting the rotating fixing shafts 25 and 26, the rotating fixing shafts 25 are started to drive the rotating shaft 26 to rotate, thereby fixing and pulling the dustproof net rolls of different widths.
[0026] The working principle of this utility model is as follows: First, a dustproof net is rolled into the rotating shaft 26. Then, the rotating fixed shafts 25 on both sides are started. The rotating fixed shafts 25 are used to roll the dustproof net to shrink it. The flattening block 18 on top is responsible for smoothing it. If cutting is required, the servo motor 2 is started. The output end of the servo motor 2 drives the rotating disk 4. When the rotating disk 4 rotates, the moving ball rod 6 moves in the rotating groove 5. When it moves to the inner wall of the rotating groove 5, the moving ball rod 6 will move inward. At this time, the moving ball rod 6 pulls the ball rod connecting block 7, the rotating rod block 8 and the pulling connecting block 9 backward, pulling the stretching block 11 backward. At the same time, it also pulls the stretching rod 15 to move, so that the flattening block 18 comes into contact and fixes the dustproof net. The flattening block 18 is used to press and fix it. Then, the rotating motor 20 is started. The rotating motor 20 drives the threaded rod 21 to rotate, which drives the cutting blade 22 on the threaded rod 21 to move and cut the dustproof net.
