Description

A vibrating screen for the production of nylon plastic particles Technical Field

[0001] This utility model belongs to the field of nylon plastic particle production technology, and specifically relates to a vibrating screen for nylon plastic particle production. Background Technology

[0002] Nylon plastic particles are thermoplastic engineering plastics made by condensation polymerization of diacids and diamines or ring-opening polymerization of lactams. The main chain contains amide groups (-CONH-), and has the characteristics of high strength, wear resistance, oil resistance, chemical corrosion resistance and good formability. There are many varieties such as PA6, PA66, PA11, etc., and the appearance is mostly milky white or slightly yellow granules.

[0003] The anti-clogging structure on the surface of a vibrating screen often needs to be replaced after a long period of use. However, the existing installation of the anti-clogging structure is mostly done by clips, bolts, or guide rails, which require manual alignment, pressing, or tightening. In addition, the operation of the anti-clogging structure also requires a separate drive component, which cannot achieve the dual function effect of a single drive component, making it quite cumbersome to use. Therefore, a vibrating screen for the production of nylon plastic particles is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a vibrating screen for the production of nylon plastic particles, the advantage of which is that a single drive component enables the operation and disassembly of the anti-clogging structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vibrating screen for the production of nylon plastic particles, including a bottom shell, a support plate slidably connected to one side inside the bottom shell, a servo motor bolted inside the support plate, a rotating rod fixedly connected to the output end of the servo motor via a coupling, both ends of the rotating rod being threaded, and the two sets of threads being arranged in opposite directions, a positioning plate being provided on the surface of each set of threads, a fixing plate being detachably connected inside the positioning plate, and the fixing plate being welded to the surface of the screening shell, a limit rod being slidably connected between the two sets of positioning plates, and the limit rod being welded to the upper end of the support plate.

[0006] The above technical solution is adopted as follows: when the servo motor runs counterclockwise, it will drive the rotating rod to rotate. The rotation of the rotating rod will cause the two sets of positioning plates to move relative to each other on the two sets of threaded surfaces, thereby positioning the positioning plate inside the fixed plate. The limiting rod is used to limit the movement of the positioning plate.

[0007] The present invention is further configured such that a rotating shaft is fixedly connected to both ends of the rotating rod surface, and a telescopic spring is connected to the rotating shaft surface through a spring fixing member, and the telescopic spring is sleeved on the rotating rod surface.

[0008] Using the above technical solution: After the positioning plate moves a certain distance on the threaded surface, it will disengage from the threaded surface. After disengaging from the thread, the positioning plate will squeeze the telescopic spring, and the telescopic spring will push the positioning plate towards one end of the thread, so that when the rotating rod rotates clockwise, it can push the positioning plate back to the threaded surface.

[0009] The present invention is further configured such that four sets of circular plates are welded to the surface of the rotating rod, and a mounting plate is slidably connected between two sets of circular plates. The mounting plate is rotatably connected to the rotating rod, and the mounting plate is detachably connected to the sliding plate.

[0010] The above technical solution is adopted: the circular plate is used to limit the range of motion of the mounting plate.

[0011] The present invention is further configured such that an arc-shaped shell is welded to one side of the mounting plate, and a toothed ring is rotatably connected between the two sets of arc-shaped shells.

[0012] The above technical solution employs an arc-shaped shell to limit the range of motion of the toothed ring.

[0013] The present invention is further configured such that an anti-clogging brush is bolted inside the toothed ring, and two sets of gears are fixedly connected to the surface of the rotating rod, with the gears meshing with the toothed ring.

[0014] The above technical solution is adopted: when the gear is driven to rotate by the rotating rod, the gear will drive the gear ring and the anti-clogging brush to rotate. The anti-clogging brush is made of nylon. Nylon bristles have high hardness, good wear resistance, oil resistance and chemical corrosion resistance, and the surface is smooth and does not easily adhere to materials.

[0015] The present invention is further configured such that spring top rods are bolted to both ends of the bottom shell, and sliding plates are bolted to the piston ends of the two sets of spring top rods, and the sliding plates are slidably connected to the bottom shell. A vibration motor is bolted to the two sets of sliding plates, a screening shell is bolted to the upper end of the two sets of sliding plates, and a receiving shell is bolted to the lower end of the two sets of sliding plates. A discharge port is welded to the surface of the screening shell.

[0016] The above technical solution is adopted: when the vibrating motor is running, it will drive the slide plate to move inside the bottom shell. Because the slide plate will squeeze the spring top rod, it will drive the screening shell to move horizontally back and forth, thereby realizing the screening of materials.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. During use, after inserting the support plate into the bottom shell, when the servo motor runs counterclockwise, it will drive the rotating rod to rotate. The rotation of the rotating rod will cause the two sets of positioning plates to move relative to each other on the two sets of threaded surfaces, thereby positioning the positioning plate inside the fixed plate. The limiting rod is used to limit the movement of the positioning plate. After the positioning plate moves a certain distance on the threaded surface, it will disengage from the threaded surface. When it disengages from the thread, the positioning plate will squeeze the telescopic spring, and the telescopic spring will push the positioning plate towards one end of the thread, so that when the rotating rod runs clockwise, it will push the positioning plate back to the threaded surface. At this time, the anti-clogging brush is set in a suitable position at the bottom of the screening shell. When the vibrating motor runs, it will drive the sliding plate to move inside the bottom shell. Because the sliding plate will squeeze the spring rod, it will cause the sliding plate to drive the screening shell to move horizontally back and forth, thereby realizing the screening of materials. The materials screened by the screening shell will be caught by the receiving shell, and the discharge port is used for discharge, achieving the effect of quick disassembly and assembly of the anti-clogging structure.

[0019] 2. When the gear rotates with the rotating rod, it will drive the gear ring to rotate inside the arc-shaped shell, thereby driving the anti-clogging brush to remove the material blocked inside the screen holes of the screening shell. The design of the mounting plate being located inside the sliding plate allows the sliding plate to support the gear ring, effectively preventing the screen holes of the screening shell from being blocked.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Example 1:

[0025] Referring to Figures 1-2, a vibrating screen for producing nylon plastic particles includes a bottom shell 1. A support plate 601 is slidably connected to one side inside the bottom shell 1. A servo motor 602 is bolted inside the support plate 601. A rotating rod 603 is fixedly connected to the output end of the servo motor 602 via a coupling. Both ends of the rotating rod 603 are provided with threads 604, and the two sets of threads 604 are arranged in opposite directions. A positioning plate 607 is provided on the surface of both sets of threads 604. A fixing plate 9 is detachably connected inside the positioning plate 607 and is welded to the surface of the screening shell 4. A limit rod 608 is slidably connected between the two sets of positioning plates 607 and is welded to the upper end of the support plate 601.

[0026] Furthermore, a rotating shaft 605 is fixedly connected to both ends of the rotating rod 603. A telescopic spring 606 is connected to the surface of the rotating shaft 605 through a spring fixing member, and the telescopic spring 606 is sleeved on the surface of the rotating rod 603.

[0027] Furthermore, four sets of circular plates 702 are welded to the surface of the rotating rod 603, and a mounting plate 703 is slidably connected between two sets of circular plates 702. The mounting plate 703 is rotatably connected to the rotating rod 603, and the mounting plate 703 is detachably connected to the sliding plate 3.

[0028] Furthermore, spring push rods 2 are bolted to both ends of the bottom shell 1. Slide plates 3 are bolted to the piston ends of the two sets of spring push rods 2. The slide plates 3 are slidably connected to the bottom shell 1. Vibration motors 5 are bolted between the two sets of slide plates 3. Screening shells 4 are bolted to the upper ends of the two sets of slide plates 3. Material receiving shells 8 are bolted to the lower ends of the two sets of slide plates 3. A discharge port 10 is welded to the surface of the screening shell 4.

[0029] Brief description of usage: In use, after inserting the support plate 601 into the bottom shell 1, when the servo motor 602 runs counterclockwise, it will drive the rotating rod 603 to rotate. The rotation of the rotating rod 603 will cause the two sets of positioning plates 607 to move relative to each other on the surfaces of the two sets of threads 604, thereby positioning the positioning plates 607 inside the fixed plate 9. The limiting rod 608 is used to limit the movement of the positioning plates 607. After the positioning plates 607 move a certain distance on the surface of the threads 604, they will disengage from the surface of the threads 604. After disengaging from the threads 604, the positioning plates 607 will compress the telescopic spring 606, and the telescopic spring 606 will... The positioning plate 607 is pushed towards one end of the thread 604, so that when the rotating rod 603 rotates clockwise, the positioning plate 607 is pushed back onto the surface of the thread 604. At this time, the anti-clogging brush 705 is set in a suitable position at the bottom of the screening shell 4. When the vibrating motor 5 runs, it will drive the sliding plate 3 to move inside the bottom shell 1. Because the sliding plate 3 will squeeze the spring top rod 2, the sliding plate 3 will drive the screening shell 4 to move horizontally back and forth, thereby realizing the screening of materials. The materials screened by the screening shell 4 will be received by the receiving shell 8, and the discharge port 10 is used for discharge, which achieves the effect of quick disassembly and assembly of the anti-clogging structure.

[0030] Example 2:

[0031] Referring to Figure 1-2, an arc-shaped shell 706 is welded to one side of the mounting plate 703, and a toothed ring 704 is rotatably connected between the two sets of arc-shaped shells 706.

[0032] Furthermore, an anti-clogging brush 705 is bolted inside the gear ring 704, and two sets of gears 701 are fixedly connected to the surface of the rotating rod 603, with the gears 701 and the gear ring 704 being meshed together.

[0033] Brief description of the usage process: When gear 701 rotates with rotating rod 603, it will drive gear ring 704 to rotate inside arc-shaped shell 706, thereby driving anti-clogging brush 705 to remove the material blocked inside the screen hole of screening shell 4. The design of mounting plate 703 located inside slide plate 3 can support gear ring 704, which can effectively prevent the screen hole of screening shell 4 from being blocked.
