Abstract
Description
Technical Field
[0001] This application relates to the field of nylon plastic granule processing technology, and more particularly to a dust removal device for nylon plastic granule processing. Background Technology
[0002] Nylon plastic granules, also known as polyamide resin, are plastics made of thermoplastic resins containing repeating amide groups. Nylon plastic granules can be produced by polycondensation of diamines and diacids, or by ring-opening polymerization of lactams formed after dehydration of amino acids. Due to their excellent properties, nylon plastic granules are widely used in many fields.
[0003] However, an existing dust removal device for nylon plastic granule processing generates certain defects, impurities, and dust during the production process, which necessitates filtration and screening. During filtration and screening, it is also necessary to avoid excessive material feeding that could lead to accumulation and affect dust removal efficiency. Utility Model Content
[0004] In view of the above problems, this application provides a dust removal device for nylon plastic granule processing to solve the problems of existing dust removal devices for nylon plastic granule processing, which generate certain defects, impurities and dust during the production process, thus requiring filtration and screening. During filtration and screening, it is also necessary to avoid large amounts of material being fed in, which would cause accumulation and affect the efficiency of dust removal.
[0005] This application provides a dust removal device for processing nylon plastic granules. It includes a filter tank, with a feed trough at the top. A first motor is mounted on one side of the feed trough, and a bidirectional lead screw is fixedly mounted on one side of the first motor. Threaded blocks are symmetrically threaded onto the outer wall of the bidirectional lead screw. A toothed groove is formed on one side of each threaded block, and a gear disk is meshed inside the toothed groove. A movable plate is mounted on one side of the gear disk, and the other side of the movable plate is sleeved onto one side of the inner wall of the feed trough.
[0006] The above method involves pouring the nylon plastic granules requiring dust removal into the feeding trough. The first motor then drives the bidirectional lead screw to rotate, causing two threaded blocks to move along the outer wall of the lead screw. This movement of the threaded blocks also moves the toothed grooves, which in turn rotate the gear disc. This rotation of the two movable plates on one side closes the switch inside the feeding trough, controlling the feeding speed and preventing the accumulation of nylon plastic granules, thus reducing the efficiency of dust removal.
[0007] In some embodiments, the inner wall of the feed trough is provided with a sliding groove, and a slider is movably sleeved inside the sliding groove. The slider is symmetrically fixed on both sides of the threaded block.
[0008] With the above scheme, when the two threaded blocks are driven, the slider slides in the groove, and the slider and groove provide stability and limit for the movement of the threaded blocks.
[0009] In some embodiments, symmetrical limiting grooves are formed on the inner wall of the filter tank, and an installation frame is movably sleeved inside the limiting groove. A filter screen is installed on the inner wall of the installation frame, and a vibration motor is installed at the bottom of the installation frame.
[0010] With the above method, when the nylon plastic particles enter the filter tank, the driving vibration motor causes the mounting frame to shake up and down in the limiting groove. Since the bottom of the filter tank is inclined, the nylon plastic particles can slide slowly up and down on the filter screen. Combined with the shaking of the filter screen, the nylon plastic particles can be vibrated and filtered to remove unqualified particles and dust.
[0011] In some embodiments, the mounting frame is inclinedly disposed on the inner wall of the limiting groove, and a telescopic spring is symmetrically embedded at the bottom of the mounting frame, with the bottom end of the telescopic spring disposed on the inner wall of the limiting groove.
[0012] With the above scheme, when the mounting frame is driven by the vibration motor to slide up and down in the limiting groove, it also drives the telescopic spring to contract. Through the telescopic spring's elasticity, it provides the mounting frame with an up-and-down shaking effect.
[0013] In some embodiments, a discharge port is provided on one side of the filter tank, and a dust collection tank is connected and installed on one side of the discharge port. A roller is installed on the inner wall of the dust collection tank, and a through hole is provided at the bottom end of the roller. A connecting pipe is installed on one side of the roller, and the connecting pipe is installed at the top of the dust box. A motor drive device is installed on one side of the dust box.
[0014] With the above method, the filtered nylon plastic particles slide slowly at the bottom of the suction tank in an inclined position. Then, the motor-driven device is operated to suck up the slowly sliding nylon plastic particles through the through holes. The dust on the surface of the nylon plastic particles enters the dust box through the roller and connecting pipe. By adjusting the suction power of the motor-driven device, the nylon plastic particles can be prevented from being adsorbed while still being sucked up, thereby achieving the effect of dust removal.
[0015] In some embodiments, the bottom of the dust collection trough is inclined, and a discharge port is provided on one side of the dust collection trough, and a collection trough is installed on the side of the discharge port.
[0016] With the above method, the dust-removed nylon plastic particles can slide at the bottom of the inner wall in an inclined manner, and fall into the collection tank through the discharge port, thereby collecting the dust-removed nylon plastic particles.
[0017] The beneficial effects of this utility model are as follows:
[0018] 1. The first motor drives the bidirectional lead screw to rotate, causing two threaded blocks to move threadedly on the outer wall of the bidirectional lead screw. The movement of the threaded blocks also drives the tooth groove to move. Through the meshing of the tooth groove, the gear disk rotates, thereby causing the movable plate on one side to rotate at an angle. The rotation of the two movable plates can close the switch inside the feed chute, thereby controlling the feeding speed. Uniform feeding avoids the accumulation of nylon plastic particles, which reduces the efficiency of dust removal. Slow feeding can improve the efficiency of dust removal.
[0019] 2. By driving the vibration motor, the mounting frame is moved up and down in the limiting groove. Since the bottom of the filter tank is inclined, the nylon plastic particles can slide slowly up and down the filter screen. Combined with the vibration of the filter screen, the nylon plastic particles can be filtered to remove unqualified particles and dust.

[0033] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0034] This application provides a dust removal device for processing nylon plastic granules. For example... Figures 1-5 As shown, it includes a filter tank 1, a feed trough 2 at the top of the filter tank 1, a first motor 3 installed on one side of the feed trough 2, a bidirectional lead screw 4 fixedly installed on one side of the first motor 3, threaded blocks 5 symmetrically threaded on the outer wall of the bidirectional lead screw 4, a toothed groove 6 opened on one side of the threaded block 5, a gear disk 7 meshing inside the toothed groove 6, a movable plate 8 installed on one side of the gear disk 7, and the other side of the movable plate 8 sleeved on one side of the inner wall of the feed trough 2.
[0035] The nylon plastic granules requiring dust removal are poured into the feed trough 2. The first motor 3 drives the bidirectional lead screw 4 to rotate, causing the two threaded blocks 5 to move threadedly on the outer wall of the bidirectional lead screw 4. The movement of the threaded blocks 5 also drives the toothed groove 6 to move. Through the meshing of the toothed groove 6, the gear disk 7 is driven to rotate, thereby causing the movable plate 8 on one side to rotate at an angle. The rotation of the two movable plates 8 can close the switch inside the feed trough 2, thereby controlling the feeding speed. By feeding evenly, the accumulation of nylon plastic granules is avoided, thus reducing the efficiency of dust removal.
[0036] In the technical solution of this application embodiment, a sliding groove 9 is provided on the inner wall of the feed trough 2, and a slider 10 is movably sleeved inside the sliding groove 9. The slider 10 is symmetrically fixed on both sides of the threaded block 5.
[0037] When the two threaded blocks 5 are driven, the slider 10 slides in the groove 9, and the slider 10 and the groove 9 provide stability and limit for the movement of the threaded blocks 5.
[0038] In the technical solution of this application embodiment, the filter tank 1 has symmetrically opened limit grooves 11 on the inner wall, the limit groove 11 is movably sleeved with an installation frame 12, the inner wall of the installation frame 12 is provided with a filter screen 13, and the bottom end of the installation frame 12 is provided with a vibration motor 14.
[0039] When the nylon plastic particles enter the filter tank 1, the drive vibration motor 14 causes the mounting frame 12 to vibrate up and down in the limiting groove 11. Since the bottom of the filter tank 1 is inclined, the nylon plastic particles can slide slowly up and down the filter screen 13. Combined with the vibration of the filter screen 13, the nylon plastic particles can be vibrated and filtered to remove unqualified particles and dust.
[0040] In the technical solution of this application embodiment, the mounting frame 12 is inclinedly disposed on the inner wall of the limiting groove 11, and a telescopic spring 15 is symmetrically embedded in the bottom of the mounting frame 12, with the bottom end of the telescopic spring 15 disposed on the inner wall of the limiting groove 11.
[0041] When the mounting frame 12 is driven by the vibration motor 14 to slide up and down in the limiting groove 11, it also drives the telescopic spring 15 to contract. Through the telescopic properties of the telescopic spring 15, the mounting frame 12 is provided with an up-and-down shaking effect.
[0042] In the technical solution of this application embodiment, a discharge port 16 is provided on one side of the filter tank 1, and a dust collection tank 17 is connected and installed on one side of the discharge port 16. A roller 18 is installed on the inner wall of the dust collection tank 17, and a through hole 19 is installed at the bottom end of the roller 18. A connecting pipe 20 is installed on one side of the roller 18, and the connecting pipe 20 is installed at the top of the dust box 21. A motor drive device 22 is installed on one side of the dust box 21.
[0043] When the filtered nylon plastic particles slide slowly at the bottom of the suction trough 17 at an incline, the motor drive device 22 is activated to suck up the slowly sliding nylon plastic particles through the through hole 19. This causes the dust on the surface of the nylon plastic particles to enter the dust box 21 through the roller 18 and connecting pipe 20. By adjusting the suction power of the motor drive device 22, the nylon plastic particles can be sucked up without being adsorbed, thereby achieving the effect of dust removal.
[0044] In the technical solution of this application embodiment, the bottom of the dust collection tank 17 is inclined, and a discharge port 23 is opened on one side of the dust collection tank 17. A collection tank 24 is installed on one side of the discharge port 23.
[0045] After dust removal, the nylon plastic particles slide along the bottom of the inner wall at an inclined position and fall into the collection tank 24 through the discharge port 23, thereby collecting the dust-removed nylon plastic particles.
