Description

Technical Field

[0001] The utility model relates to the technical field of ABS particles, in particular to a screening machine for ABS particle production. Background Art

[0002] ABS plastic is a ternary copolymer of acrylonitrile (A), butadiene (B), and styrene (S). The relative content of the three monomers can be changed arbitrarily to make various resins. ABS plastic particles need to be screened before use to prevent some large particles that do not meet the specifications from affecting subsequent processing;

[0003] Existing ABS particle screening machines often use a vibrator to drive the screen to vibrate, and then the ABS particles, along with the vibration of the screen, the particles that meet the operation will fall through the screen;

[0004] This conventional screening method of using a vibrator to drive the screen has some minor problems. For example, the vibrator has a large power, the vibration drive method is relatively simple, some particles rub against each other, and the particles that meet the requirements of the operation will be re-grinded and turned into debris. Some larger particles are affected by their own plasticity and cannot be broken or discharged from the screen, affecting subsequent processing. For this reason, we propose a screening machine for ABS particle production. Utility Model Content

[0011] Furthermore, it also includes a control switch, which is arranged on the rear side of the left side of the shell, and the input end of the control switch is electrically connected to an external power supply to control the normal operation of the motor.

[0012] Furthermore, the reciprocating flipping mechanism includes a rotating shaft, a first gear, a half gear and a second gear. The first gear is also connected to the rear inner wall of the shell through the rotating shaft so as to rotate symmetrically left and right. The two first gears are meshed and connected. The front ends of the two first gears are each provided with a half gear. A second gear is provided in the middle of the rear side surface of the rear turntable. The two half gears are each installed in cooperation with a second gear to provide a reciprocating rotation structure for it.

[0017] When it is necessary to screen the ABS particles, the control switch can be adjusted to run the motor, and the output shaft of the motor rotates, thereby driving the two first gears to rotate in the opposite direction relative to each other, thereby driving the two half gears to rotate in the opposite direction relative to each other, thereby driving the two half gears 43 to rotate in the opposite direction relative to each other, and then the left half gear 43 drives the second gear 44 to rotate in the clockwise direction at a specified angle, and then drives the screen 33 to rotate in the clockwise direction at a specified angle through the rear turntable 31 and the support rod 32.

[0027] The reciprocating flip mechanism 4 is arranged on the inner wall of the rear side of the shell 1. The reciprocating flip mechanism 4 is fixedly connected to the rear turntable 31. The reciprocating flip mechanism 4 includes a rotating shaft 41, a first gear 42, a half gear 43 and a second gear 44. The first gear 42 is also connected to the inner wall of the rear side of the shell 1 by rotating symmetrically on the left and right sides of the rotating shaft. The two first gears 42 are meshed and connected. The front ends of the two first gears 42 are each provided with a half gear 43. The middle part of the rear side surface of the rear turntable 31 is provided with a second gear 44. The two half gears 43 are each installed in cooperation with a second gear 44. The motor 5 is also included. The motor 5 is arranged on the rear side wall of the shell 1.

At this time, the half gear 43 on the left side drives the second gear 44 to rotate in the clockwise direction at a specified angle, and then the screen 33 is driven to rotate in the clockwise direction at a specified angle through the rear turntable 31 and the support rod 32. After rotating at the specified angle, the half gear 43 on the left side is disengaged from the meshing with the second gear 44, and then the half gear 43 on the right side is driven to rotate in the clockwise direction at a specified angle. The half gear 43 is meshed with the second gear 44, and then the half gear 43 on the right drives the second gear 44 to reset counterclockwise, thereby driving the entire rear turntable 31 to reset in the opposite direction, and then the above mechanical movement is repeated over and over again, thereby driving the screen 33 to reciprocate. At this time, the external ABS particles can enter the screen 33 along with the feed hopper 9. Under the influence of gravity, these ABS particles move obliquely to the lower right side and are reciprocated by the screen 33. The screened ABS particles fall into the discharge hopper 8, and the large particles are discharged to the outside of the screening machine along the slag outlet 35 and the slag outlet plate 36.
