Description

Technical Field

[0001] The utility model relates to the technical field of plastic granule screening devices, and specifically relates to a vibration screening device for PA plastic granule processing. Background Technique

[0002] PA is the chemical abbreviation of Polyamide. Polyamide is a tough, angular, translucent or milky white crystalline resin. The molecular weight of polyamide as an engineering plastic is generally 15,000 - 30,000. Polyamide has high mechanical strength, high softening point, heat resistance, low coefficient of friction, wear resistance, self-lubrication, shock absorption and sound absorption properties, oil resistance, resistance to weak acids, alkalis and general solvents, good electrical insulation, self-extinguishing property, non-toxic, odorless, good weather resistance, and poor dyeability. The disadvantage is its high water absorption, which affects dimensional stability and electrical properties. Fiber reinforcement can reduce the water absorption rate of the resin, enabling it to work at high temperatures and high humidity.

[0003] During the processing of PA plastic granules, it is necessary to screen them. The screen meshes of existing plastic vibration screening devices are usually inconvenient to remove and replace, so as to adjust the aperture size of the screen mesh to adapt to screening plastic granules of different diameters.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4, the present utility model discloses a vibration screening device for processing PA plastic particles, including a fixed frame 1. On one side of the top of the fixed frame 1, a drive box 2 with a built-in motor is fixedly connected. A through groove 3 is formed on the top of the fixed frame 1 on one side of the drive box 2. Above the fixed frame 1, a movable frame 4 in a rectangular ring shape is movably connected. On the top of the movable frame 4, a sieve plate 5 is detachably connected. At the four corners of the top of the movable frame 4, fixing screws 13 are fixedly connected. Through holes through which the fixing screws 13 pass are formed at the four corners of the top of the sieve plate 5. The fixing screws 13 are threadedly connected with wing nuts 14 that press the sieve plate 5. On both outer walls of the movable frame 4, upper fixing blocks 10 are fixedly connected. On both outer walls of the fixed frame 1, lower fixing blocks 11 corresponding to the upper fixing blocks 10 are fixedly connected. The upper fixing blocks 10 and the lower fixing blocks 11 corresponding up and down are connected by elastic pieces 12. On both sides of the drive box 2, swing rods 8 driven by the motor in its inner cavity are provided. The swing rods 8 are hinged with connecting rods 9. On one side of the bottom of the movable frame 4, an ear block 7 hinged with the connecting rod 9 is fixedly connected. By the rotation of the swing rods 8 to drive the connecting rods 9 to drive the sieve plate 5 to vibrate reciprocally, it is convenient to remove the sieve plate 5 for replacement, and thus convenient to adjust the aperture size of the sieve plate during screening.

[0019] Between the upper fixing blocks 10 and the lower fixing blocks 11 corresponding up and down, they can also be connected by springs to replace the elastic pieces 12 for connection.

[0020] The motor inside the drive box 2 is a double-headed motor. The output shaft of the double-headed motor penetrates the drive box 2 and is connected to the swing rod 8. When the swing rod 8 is driven to rotate, it can drive the movable frame 4 and the sieve plate 5 to swing reciprocally through the connecting rod 9. Because the lower fixing blocks 11 on the outer wall of the fixed frame 1 and the upper fixing blocks 10 on the outer wall of the movable frame 4 are connected by elastic pieces 12, the sieve plate 5 will vibrate during the swinging process to facilitate the screening of plastic particles.

[0021] Specifically, on one side of the top of the sieve plate 5, a groove 6 is formed. On the bottom inner wall of the groove 6, sieve holes are formed.

[0022] In this implementation, the groove 6 cooperates with the through groove 3.

[0023] Specifically, at the four corners of the bottom of the fixed frame 1, support legs 15 are fixedly connected.

[0024] Between two support legs 15 on the same side of the bottom of the fixed frame 1, a stabilizing rod 16 is connected.

[0025] In this implementation, the cooperation of the support legs 15 and the stabilizing rod 16 can lift the fixed frame 1 so as to place a corresponding container for collecting plastic particles below the fixed frame 1.

[0026] Specifically, one side of the support leg 15 is fixedly connected with a mounting block 17, and a universal wheel 18 with a self-locking function is installed at the bottom of the mounting block 17.

[0027] In this embodiment, the setting of the universal wheel 18 facilitates the overall movement of the device.

[0028] Specifically, an adjusting screw 19 with an end penetrating through the stabilizing rod 16 is threadedly connected to the stabilizing rod 16, and a stabilizing foot 20 is connected to the bottom end of the adjusting screw 19.

[0029] In this embodiment, by tightening the adjusting screw 19, the stabilizing foot 20 can be made to contact the ground to ensure the overall stability of the screening device.

[0030] In summary, for the vibrating screening device for PA plastic particles processing, the swing rod 8 rotates to drive the connecting rod 9 to drive the sieve plate 5 to vibrate reciprocally, which facilitates the removal of the sieve plate 5 for replacement, and further facilitates the adjustment of the aperture size of the sieve plate during the screening process.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
