Description

Technical Field

[0001] This invention relates to the field of mechanical metal expandable mesh, specifically to a metal expandable mesh processing apparatus. Background Technology

[0002] Extended metal mesh is a process that involves cutting and stretching sheet metal to create a continuous mesh pattern. Unlike woven or welded mesh, extended metal mesh is made from a single piece of metal, thus eliminating joints or welds. This results in higher strength and durability. The extended metal process produces high-strength, lightweight, and durable metal mesh suitable for applications such as wind power, aviation lightning protection, electromagnetic shielding, construction (e.g., fences, security systems), industrial applications (e.g., ventilation grilles, filters), and decorative uses (e.g., architectural decoration).

[0003] In the processing of metal mesh, metal plates need to be cut into a series of slits or gaps. During the cutting process, corresponding processing waste is generated. Existing equipment cannot collect it continuously and centrally. The accumulation of waste will interfere with the production process, reduce work efficiency, and workers need to spend extra time cleaning the waste at the bottom of the equipment, thereby reducing the time available for actual production.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-9This invention provides a technical solution: a metal expanded mesh processing device, comprising: an n-shaped equipment frame 1, a lifting plate 3 vertically mounted in the middle of the equipment frame 1, a driving unit above the lifting plate 3 for reciprocating lifting and lowering, a punch 7 at the bottom of the lifting plate 3, the punch 7 being a cutter with a rhomboid or rectangular cross-section, a supporting mesh plate 8 in the middle of the equipment frame 1, the supporting mesh plate 8 having through holes that mate with the punch 7, the through holes corresponding one-to-one with the punch 7; a collecting mechanism located below the supporting mesh plate 8, the collecting mechanism including a collecting trough 9 fixed to the bottom of the supporting mesh plate 8 and two conveying rollers 10 rotatably mounted in the middle of the equipment frame 1, the collecting trough 9 having a shaftless spiral rotatably connected inside. The blade 11, one end of the shaftless helical blade 11 is fixedly connected to the drive shaft 13, the drive shaft 13 is rotatably connected to the collection tank 9, and a linkage part is provided on the outside of the drive shaft 13. When the lifting plate 3 moves downward, the linkage part does not drive the drive shaft 13 to rotate. When the lifting plate 3 moves upward, the linkage part drives the drive shaft 13 to make the shaftless helical blade 11 transport waste. At the same time, the drive shaft 13 drives the conveying roller 10 to transport the metal plate forward. The stretching mechanism is placed on one side of the equipment frame 1. The stretching mechanism includes a stretching frame 24. The top of the stretching frame 24 is provided with a clamping part for stretching and a sliding plate 33. The middle of the sliding plate 33 is provided with a buffer part to increase the conveying space during stretching and to perform tensile strength testing.

[0030] It should be noted that the present invention is equipped with a controller and a corresponding operation panel. The metal plate is placed on top of the support mesh plate 8, and its end is placed between the two conveying rollers 10. During operation, the drive unit drives the lifting plate 3 to move up and down reciprocally. When the lifting plate 3 moves downward, the drive shaft 13 is stationary under the action of the linkage unit. The lifting plate 3 drives the punch 7 to cut the metal plate through the upper mold 6, thereby cutting the metal plate into a series of straight cuts or irregular holes. The waste material from the stamping and cutting falls into the collection tank 9 through the through hole of the support mesh plate 8. When the lifting plate 3 moves upward, it drives the drive shaft 13 to rotate. The drive shaft 13 drives the shaftless spiral blade 11 to rotate. The shaftless spiral blade 11 collects the cutting waste material inside the collection tank 9. Discharged from one end, when the drive shaft 13 rotates, the drive shaft 13 drives the conveyor roller 10 to rotate through the transmission belt assembly 20. The conveyor roller 10 conveys the metal plate forward, and the burrs generated by cutting can be flattened by the extrusion of the conveyor roller 10. The top of the stretching frame 24 is equipped with an infrared sensor. When the cut metal plate enters the moving frame 25, the pressure plate 27 fixes the end of the metal plate, the pressure plate 31 fixes the other end of the metal plate downward, and the metal plate is cut by the cutter 32. The moving frame 25 moves to one end to stretch the metal plate. When the plate is stretched, the metal gap is stretched into a diamond-shaped hole or other pattern, thereby making the metal plate into a metal mesh through cutting and stretching.

[0031] like Figure 1 ,2 As shown in Figure 3, the drive unit includes a crankshaft 22 rotatably mounted on the top of the equipment frame 1. A motor 23 is fixedly connected to the top of the equipment frame 1. The motor 23 is connected to the crankshaft 22 via a transmission belt assembly. A connecting rod 1 is rotatably connected to the middle of the crankshaft 22. A connecting rod 22 4 is rotatably connected to the bottom of the connecting rod 1. The connecting rod 22 4 is fixedly connected to the lifting plate 3. A limit baffle 2 is fixedly connected to the inner side of the equipment frame 1. The limit baffle 2 is slidably connected to the lifting plate 3. A lifting slide rod 5 is fixedly connected to the top of the limit baffle 2. The lifting plate 3 is slidably connected to the lifting slide rod 5.

[0032] It should be noted that, in this invention, the motor 23 drives the large pulley to rotate via a small pulley and a transmission belt. The large pulley drives the crankshaft 22 to rotate. Connecting rod one is rotatably connected to the middle of the crankshaft 22, transmitting the rotational motion of the crankshaft to the lifting part. The bottom of connecting rod two 4 is fixedly connected to the lifting plate 3, thereby driving the lifting movement of the lifting plate 3. The function of the limiting baffle 2 is to limit the range of motion of the lifting plate, preventing the lifting plate 3 from exceeding the predetermined upper and lower stroke. The limiting baffle 2 and the lifting plate 3 are slidably connected, and the limiting guide ensures that the lifting plate 3 can move stably during lifting. A lifting slide rod 5 is fixedly connected to the top of the limiting baffle 2. The lifting plate 3 is slidably connected to the equipment frame through the lifting slide rod, ensuring that the lifting plate 3 can move smoothly up and down. The motor 23 drives the crankshaft 22 to rotate, the crankshaft 22 drives the movement of connecting rod one, and then drives the lifting plate 3 to move up and down through connecting rod two 4. The slidable connection between the limiting baffle 2 and the lifting plate 3 and the lifting slide rod 5 ensure that the lifting plate 3 moves smoothly up and down within the specified range.

[0033] like Figure 2 , 3 As shown, the bottom of the lifting plate 3 is fixedly connected to the upper mold 6, the punch 7 is fixedly connected to the bottom of the upper mold 6, the outside of the punch 7 is slidably connected to the pressure plate, and a return spring is installed between the pressure plate and the upper mold 6.

[0034] It should be noted that in this invention, the lifting plate 3 drives the upper mold 6 to move downward. Under the action of the return spring, the pressure plate first contacts the metal plate and presses and fixes the metal plate by the elastic force of the return spring. When the punch 7 penetrates the pressure plate and contacts the metal plate, it cuts the metal plate. When the lifting plate 3 drives the upper mold 6 to move upward, the punch 7 separates from the metal plate. Then, the upper mold 6 drives the pressure plate to separate from the metal plate by the return spring, thereby preventing the punch 7 from lifting the metal plate and preventing the metal plate from being misaligned.

[0035] like Figure 2 , 3As shown, two conveying rollers 10 are arranged one above the other for conveying metal plates, leveling them, and removing sharp edges from the metal plates. One end of each conveying roller 10 is fixed with a transmission gear 21, and the two transmission gears 21 mesh with each other. One side of the lower conveying roller 10 is connected to the drive shaft 13 via a transmission belt assembly 20.

[0036] It should be noted that when the lifting plate 3 moves upward, the lifting plate 3 drives the gear 14 to rotate, and the gear 14 drives the inner ratchet 15 to rotate. Because there is a movement gap between the inner ratchet 15 and the pawl 17, during the transmission process of the pawl 17 and the inner ratchet 15, the punch 7 can quickly separate from the metal plate due to the small thickness of the metal plate. When the pawl 17 and the inner ratchet 15 are in transmission, the gear 14 drives the drive disk 16 to rotate through the inner ratchet 15 and the pawl 17. The drive disk 16 drives the drive shaft 13 to rotate. The drive shaft 13 drives the conveyor roller 10 located below to rotate through the belt and pulley. The conveyor roller 10 rotates under the transmission action of the transmission gear 21. During the upward movement of the lifting plate 3, the conveyor roller 10 conveys the cut metal plate forward. During the conveying process, under the squeezing action, the conveyor roller 10 squeezes the cut metal plate to flatten the cutting burrs.

[0037] like Figure 2 , 3 As shown in Figures 4 and 5, the linkage includes a drive rack 12 fixedly connected to the side of the lifting plate 3. The drive rack 12 is slidably connected to the equipment frame 1. A gear 14 is meshed with the outer side of the drive rack 12. The gear 14 is rotatably connected to the drive shaft 13. An inner ratchet 15 is fixedly connected inside the gear 14. A drive disk 16 is rotatably connected inside the gear 14. The drive shaft 13 is fixedly connected to the drive disk 16. A storage groove 19 is provided on the outer side of the drive disk 16. A pawl 17 for driving the inner ratchet 15 is rotatably connected inside the storage groove 19. A spring 18 is fixedly connected between the pawl 17 and the inner wall of the storage groove 19. When the gear 14 rotates clockwise, the pawl 17 is slidably connected to the inner ratchet 15. When the gear 14 rotates counterclockwise, the inner ratchet 15 drives the drive disk 16 to rotate through the pawl 17. The drive disk 16 drives the shaftless spiral blade 11 to transport waste material outward through the drive shaft 13.

[0038] It should be noted that the device frame 1 of the present invention is provided with a sliding hole that cooperates with the drive rack 12. During the lifting process, the lifting plate 3 drives the drive rack 12 to move up and down. When the drive rack 12 moves downward, it drives the gear 14 to rotate clockwise. The gear 14 drives the inner ratchet 15 to rotate clockwise. Under the inclined structure, the inner ratchet 15 squeezes the pawl 17 and slides with it. The pawl 17 squeezes the spring 18 and rotates into the receiving groove 19. Thus, the inner ratchet 15 does not transmit power to the drive disc 16, and the drive shaft 13 and the conveying roller 10 are both in a stationary state. When the lifting plate 3 moves upward, the drive rack 12... The gear 14 is driven to rotate counterclockwise by the spring 18. Under the action of the spring force, the pawl 17 is engaged in the tooth gap of the inner ratchet 15. The gear 14 cooperates with the pawl 17 through the inner ratchet 15. The inner ratchet 15 drives the drive disk 16 to rotate through the pawl 17. The drive disk 16 drives the drive shaft 13 to rotate. The drive shaft 13 drives the shaftless spiral blade 11 to transport metal. The drive shaft 13 drives the conveyor roller 10 to work through the transmission belt assembly 20. This cycle is repeated so that when cutting downwards, the conveyor roller 10 and the shaftless spiral blade 11 are stationary. After cutting is completed, the shaftless spiral blade 11 and the conveyor roller 10 rotate to discharge waste and transport it.

[0039] like Figure 6 , 7 As shown in Figures 8 and 9, the tension frame 24 is fixedly connected to one side of the equipment frame 1. A movable frame 25 is slidably connected to the top of the tension frame 24. The movable frame 25 has a "U"-shaped structure and is used to fix the traction and unloading of the metal mesh. A hydraulic cylinder 26 is fixedly connected to the top of the movable frame 25. A pressure plate 27 is fixedly connected to the output end of the hydraulic cylinder 26. Linear modules 28 are fixedly connected to both sides of the tension frame 24. The movable slide of the linear module 28 is fixedly connected to the movable frame 25. A sliding plate 33 is slidably connected to the top of the tension frame 24 near the equipment frame 1. A limit hole 34 is opened in the middle of the sliding plate 33. A limit block is slidably connected inside the limit hole 34. The limit block is fixedly connected to the tension frame 24. A spring 36 is fixedly connected to one end of the limit block. A pressure sensor 35 is connected to one end of the spring 36. The pressure sensor 35 is connected to the limit block. The sliding plate 33 is fixedly connected to the hole 34. The top of the sliding plate 33 is fixedly connected to the movable frame 29. The top of the movable frame 29 is fixedly connected to the hydraulic cylinder 20. The output end of the hydraulic cylinder 20 is fixedly connected to the pressure plate 21. The side of the pressure plate 21 is fixedly connected to the cutter 32. The top of the sliding plate 33 is provided with a groove that mates with the cutter 32. The side of the sliding plate 33 is fixedly connected to the support plate 37, which is used to support the metal mesh and guide the movable frame 25. The support plate 37 passes through the bottom of the movable frame 25 and is slidably connected to the movable frame 25.

[0040] It should be noted that, under the conveying action of the conveying roller 10, the cut metal plate is a metal mesh structure. The metal mesh passes through the middle of the moving frame 29 and is conveyed forward. The metal mesh moves from the top of the support plate 37 toward the moving frame 25. The bottom of the inner wall of the moving frame 25 is a sloping structure to facilitate the insertion of the metal mesh into the moving frame 25. The support plate 37 and the moving frame 25 are slidably connected to facilitate the movement of the moving frame 25 on the top of the tension frame 24. The height of the cutter 32 is adjusted by the hydraulic cylinder 30 so that the bottom of the cutter 32 is slidably connected with the conveyed metal mesh, thereby scraping off the burrs on the metal mesh. Furthermore, under the limiting action of the cutter 32, a polishing motor can also be installed on one side of the moving frame 29. The output end of the polishing motor... A polishing wheel is fixedly connected to the metal surface for polishing. At this time, the moving frame 25 is located in the middle of the stretching frame 24. When the end of the metal mesh enters the moving frame 25, under the action of an infrared sensor, the controller controls hydraulic cylinders 26 and 30 to extend. Hydraulic cylinder 26, through pressure plate 27, presses and fixes the end of the metal mesh inside the moving frame 25. Hydraulic cylinder 30 drives pressure plate 31 to press and fix the metal mesh inside the moving frame 29. Because the bottom of the cutter 32 is lower than the height of pressure plate 31, pressure plate 31 can cut the metal mesh. After pressure plate 31 presses and fixes the cut metal mesh, the linear module 28 drives the moving frame 25 to one end, thereby cutting the metal mesh. The metal mesh is stretched to open the gaps into a grid pattern. During the stretching process, one end of the metal mesh drives the sliding plate 33 forward, which in turn drives the pressure sensor 35 to move to one end, thus providing a certain conveying space for the subsequent conveyed metal mesh. Because the limiting block is fixed to the stretching frame 24 and slidably connected to the limiting hole 34, the limiting block compresses the pressure sensor 35 through the second spring 36. When the pressure value reaches the specified value, the stretching stops, the first hydraulic cylinder 26 quickly resets, and the linear module 28 drives the first moving frame 25 to one end of the second moving frame 29. When the first moving frame 25 approaches the second moving frame 29, under the action of the limit switch, the first hydraulic cylinder 26 drives the pressure plate 27 to clamp the stretched mesh. Cylinder 2 (30) controls the resetting of pressure plate 2 (31). The linear module 28 moves the moving frame 25, pushing the stretched metal mesh to one end. When the moving frame 25 reaches the end of the stretching frame 24, the hydraulic cylinder 26, under the action of the limit switch, drives the pressure plate 27 to reset. The end of the metal mesh separates from the moving frame 25 under gravity. For separate tensile strength testing of the stretched metal mesh, hydraulic cylinder 2 (30) drives pressure plate 2 (31) to fix one end of the metal mesh, and hydraulic cylinder 26 drives pressure plate 27 to clamp and fix the other end of the metal mesh. The linear module 28 drives the moving frame 25 to move to one end. Under the pulling force, hydraulic cylinder 26 applies pressure to the pressure sensor 35. During the stretching process...The value of pressure sensor 35 gradually increases, and when the metal mesh breaks, the value of pressure sensor 35 decreases. The maximum value is used to determine the tensile strength of the metal mesh.
