Description

Technical Field

[0001] The present invention relates to the technical field of fiber cutting equipment, in particular to a fiber chopper. Background Art

[0002] Glass fiber is an inorganic, non-metallic material with excellent properties, available in a wide variety. Its advantages include excellent insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but its disadvantages include brittleness and poor wear resistance. It is manufactured from six minerals: pyrophyllite, quartz sand, limestone, dolomite, colemanite, and magnesiaite, through high-temperature melting, drawing, winding, and weaving processes. The diameter of a single fiber ranges from a few microns to more than 20 microns, equivalent to 1 / 20 to 1 / 5 the diameter of a human hair. Each fiber strand is composed of hundreds or even thousands of individual filaments. Glass fiber is commonly used as a reinforcement in composite materials, electrical insulation and thermal insulation materials, circuit boards, and other applications in various sectors of the national economy.

[0014] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. This fiber chopper starts the dust collection component in the cutting mechanism synchronously during the cutting process, and uses negative pressure to directly collect the dust generated by cutting, preventing the dust from spreading in the machine body and reducing the risk of operators being exposed to dust. It also controls dust accumulation at the source, maintains the cleanliness of the equipment's moving parts, prevents dust from interfering with the mechanical transmission accuracy, and extends the service life of the equipment.

[0015] 2. In this fiber chopping machine, the cutting mechanism absorbs the instantaneous impact force when the cutter descends through a spring, reducing the damage to the tool caused by vibration; at the same time, after cutting is completed, the cutter is automatically polished by the polishing component when the adjustment frame rises. Under the linkage of the two, the cutter can not only reduce loss through elastic buffering during cutting, but also continue to remain sharp, avoiding uneven cutting or increased dust caused by tool blunting, and further optimizing the dust control effect.

[0016] 3. This fiber chopping machine has an anti-static mechanism that grounds the static electricity of the fiber through a metal plate. At the same time, the rotating rod and the connecting rope are linked to drive the elastic knocking rod to vibrate the metal plate when the cutting mechanism is raised and lowered. The static electricity is eliminated and the adsorption force between the fiber and the dust is weakened. The vibration causes the dust to fall off the fiber surface through the sieve hole through the physical effect and fall into the collection box.

[0017] 4. This fiber chopper captures fine dust raised by the vibration of the static removal mechanism through the electrostatic adsorption plate in the adsorption mechanism, forming a second line of filtration defense. At the same time, the rotating rod drives the screw through the synchronous pulley to drive the cleaning roller to move and rotate, automatically removing the dust on the surface of the electrostatic adsorption plate, avoiding the adsorption plate from failing due to dust accumulation. It not only ensures efficient dust capture, but also maintains the long-term stability of the adsorption function through automated maintenance, solving the pain point of traditional electrostatic adsorption equipment that requires frequent manual cleaning.

[0018] 5. This fiber chopper has established a dust control system covering the entire chain of "generation-adhesion-suspension", from instant dust collection during cutting, static elimination and vibration dust removal during blanking, to adsorption and automatic cleaning of suspended dust. The various mechanisms share the power source through mechanical linkage, reducing additional energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating shaft 311 is rotatably connected to the inner wall of the body 1 through a torsion spring. The swing frame 312 is fixedly sleeved on the rotating shaft 311. The transverse slot 313 is opened on the inner wall of the body 1. The moving block 314 is slidably connected to the inner wall of the transverse slot 313, and the moving block 314 moves through the inner wall of the swing frame 312. The mounting plate 315 is fixedly connected to the moving block 314. The grinding stone 316 is mounted on one side of the mounting plate 315. A limiting slot is provided on the inner wall of the body 1, and the limiting slot is directly above the transverse slot 313. The inner wall of the limiting slot is slidably connected to the limiting block, and the limiting block is fixedly connected to the moving block 314. The rotating shaft 311 and the swing There are four movable frames 312, and the four swing frames 312 are symmetrically arranged on both sides of the adjustment frame 34. The static electricity removal mechanism 4 includes a metal plate 41, a sieve hole 42, a rotating rod 43, a connecting rope 44, an elastic knocking rod 45, and a collection box 46. The metal plate 41 is fixed on the inner wall of the body 1, and the metal plate 41 is connected to the ground through a grounding wire. The sieve hole 42 is opened on the metal plate 41. The rotating rod 43 rotates through the outer wall of the body 1 through a torsion spring and is rotatably connected to the inner wall of the body 1.

The elastic knocking rod 45 is arranged on the rotating rod 43, and the collection box 46 is arranged at the bottom of the metal plate 41.

[0026] Working principle: The glass fiber is transported by the conveyor belt 2. When the glass fiber is transported to the bottom of the cutter 35, the hydraulic cylinder 31 is activated to drive the lifting plate 32 to descend, thereby driving the adjustment frame 34 to descend through the spring 33. The adjustment frame 34 drives the cutter 35 to descend to chop the glass fiber. The glass fiber has high hardness. When chopping, the cutter 35 is easily vibrated by the instantaneous impact. The elastic deformation of the spring 33 absorbs the impact energy, thereby protecting the cutter 35. By starting the vacuum cleaner 36, the vacuum cleaner 36 generates suction through the connecting pipe 37 to the vacuum pipe 38. The dust generated during the cutting process is absorbed to prevent dust from flying. When the cutter 35 is finished cutting and rises, the two sides of the adjustment frame 34 will contact the swing frame 312, thereby driving the swing frame 312 to rotate along the rotating shaft 311, thereby driving the moving block 314 to move along the transverse groove 313, thereby driving the mounting plate 315 to move, so that the grindstone 316 contacts the cutter 35. At this time, the cutter 35 continues to rise, thereby grinding the cutter 35 through the grindstone 316 to ensure the sharpness of the cutter 35. When the cutter 35 descends, the adjustment frame 34 separates from the swing frame 312. Under the action of the torsion spring, the swing frame 312 is driven to reset, thereby driving the grinding stone 316 to reset, preventing the grinding stone 316 from affecting the descent of the cutter 35. The chopped glass fiber will fall onto the metal plate 41. Due to the strong insulation of the glass fiber, it is easy to generate static electricity through friction during the cutting movement, and static electricity will absorb dust. The hydraulic cylinder 31 drives the adjustment frame 34 to rise, which will pull the connecting rope 44, thereby driving the rotating rod 43 to rotate. When the adjustment frame 34 descends, the torsion spring will retract the connecting rope 44, thereby driving the rotating rod 43 to reverse, and the rotating rod 43 will rotate. The forward and reverse rotation of 3 drives the elastic knocking rod 45 to knock on the bottom of the metal plate 41, causing the glass fiber on the metal plate 41 to shake and fall. When the glass fiber collides with the metal plate 41, charge transfer occurs on the contact surface. The shaking causes the fiber to repeatedly contact and separate, accelerating the charge extraction, and transferring the static electricity of the glass fiber to the metal plate 41, and then to the ground through the grounding wire to avoid dust accumulation. At the same time, the vibration can overcome the Coulomb force between the fiber and the metal plate 41, making it easier for the charged dust to fall off. The fallen dust will fall into the collection box 46 through the sieve hole 42 for collection.

[0027] See also Figure 1-10On the basis of the above embodiment, in another embodiment of the present invention, preferably, the adsorption mechanism 5 includes an electrostatic adsorption plate 51, a screw 52, ​​a moving frame 53, a cleaning roller 54, a gear 55, a rack 56, and a limit rod 57. The electrostatic adsorption plate 51 is installed inside the body 1, and the electrostatic adsorption plate 51 is above the metal plate 41. The screw 52 rotates through the outer wall of the body 1 and is rotatably connected to the inner wall of the body 1. The screw 52 is connected to the rotating rod 43 through a synchronous pulley. The moving frame 53 is threadedly sleeved on the screw 52. The cleaning roller 54 is rotated and connected Connected to the inner wall of the movable frame 53, the gear 55 is fixedly sleeved on one end of the cleaning roller 54, the rack 56 is fixed on the inner wall of the body 1, and the rack 56 passes through the movable frame 53 and is meshed with the gear 55, the limiting rod 57 is fixed on the inner wall of the body 1, and the limiting rod 57 movably passes through the movable frame 53, a receiving groove 58 is provided at the bottom of the inner wall of the movable frame 53, a scraper 59 is provided at the bottom of the inner wall of the receiving groove 58, and the scraper 59 is in contact with the bottom of the cleaning roller 54, a cleaning port is provided on one side of the movable frame 53, and a pumping block 510 is provided on the cleaning port.

[0028] Working principle: When the glass fiber shakes on the metal plate 41, static electricity is generated through the electrostatic adsorption plate 51, and the dust flying in the shake is electrostatically adsorbed, thereby further removing the dust in the glass fiber. At the same time, the synchronous pulley drives the screw rod 52 to rotate when the rotating rod 43 rotates. The rotation of the screw rod 52 drives the moving frame 53 to move, and the movement of the moving frame 53 drives the cleaning roller 54 to move. At the same time, under the action of the gear 55 and the rack 56, the cleaning roller 54 rotates while moving, cleaning the dust adsorbed on the electrostatic adsorption plate 51. The cleaning roller 54 is then cleaned by the scraper 59 below, causing the dust to fall into the receiving groove 58 for collection. The dust in the receiving groove 58 can be cleaned by pulling the withdrawal block 510 outward. It is worth noting that the rotation of the rotating rod 43 is determined by the lifting and lowering of the lifting block 310 through the connecting rope 44. When the lifting block 310 rises to the top, the rotating rod 43 drives the screw rod 52 to rotate. At this time, the moving frame 53 is at one end of the screw rod 52. When the lifting block 310 descends to the bottom, the rotating rod 43 is reset under the action of the torsion spring, and the rotating rod 43 drives the screw rod 52 to reverse. At this time, the moving frame 53 is at the other end of the screw rod 52.
