Description

Technical Field

[0001] The utility model belongs to the technical field of functional plastic master batches, in particular to a functional plastic master batch feeding device. Background Art

[0002] Plastic masterbatch is composed of excess chemical additives, carrier resins and dispersants. In the process of plastic processing and molding, for the convenience of operation, the required various additives, fillers and a small amount of carrier resin are first mixed and kneaded, and then the granular material is obtained through the process of metering, mixing, melting, extrusion, pelletizing and other processing by extruders and other equipment. A feeding device is required when processing plastic masterbatch.

[0003] A Chinese patent with the publication number CN212826258U discloses a vibrating feeding device for functional plastic masterbatch, including a bottom tube, a barrel is provided at the top of the bottom tube, a screen is provided at the bottom of the inner cavity of the barrel, a slider is fixedly provided on one side of the screen, a slide bar is fixedly provided on the other side of the screen, and the screen is movably connected to the barrel through the slider and the slide bar, and a limit block is fixedly provided at the end of the slide bar. The utility model drives the eccentric block to rotate through a double-headed motor, so that the barrel vibrates on the bottom tube through a second spring, and when the convex part of the eccentric block rotates and is located at the slider, the slider can be pushed to move left, and the slider pushes the screen to move left. When the convex part of the eccentric block rotates away from the slider, the first spring drives the screen to return to the initial position through the slide bar, and continuous operation can make the screen vibrate left and right. The feeding device can quickly feed and avoid blockage when feeding plastic masterbatch through the cooperation of internal vibration and external vibration, and has high working efficiency.

[0004] As mentioned above, the patent provides a vibrating feeding device for functional plastic masterbatch. Although it can quickly feed materials through the cooperation of internal vibration and external vibration, it uses a first spring to cooperate with a slide rod to push the screen to achieve reciprocating sliding, and it moves relatively on a horizontal plane. Functional plastic masterbatch accumulates on the screen, and part of the functional plastic masterbatch at the bottom may adhere to the screen, which will cause it to move with the left and right movement of the screen, and always adhere to the screen. As more and more attached, it is easy to cause the screen to be blocked, affecting feeding.

[0005] Therefore, a functional plastic masterbatch feeding device is proposed to solve the above problems. Utility Model Content

In addition, the driving pulley 9 rotates and drives the driven pulley 10 to rotate through the belt. The driven pulley 10 rotates and drives the worm 11 to rotate. The worm 11 drives the worm wheel 8 to rotate, and then drives the middle reciprocating screw 7 to rotate. The middle reciprocating screw 7 rotates in coordination with the large gear 6 and the small gear 5 to drive the two rotating shafts 3 to rotate, so as to realize the rotation of the three-leaf cam 4, and beat the elastic screen plate 2 so that the functional plastic masterbatch attached to its surface can be ejected and then fall from the elastic screen plate 2. When the particles are too large to pass through, they will be ejected and will not affect the passage of other elastic screen plates 2. At the same time, a spiral guide plate 13 is provided to guide the elastic screen plate 2 to avoid serious accumulation and blockage, thereby ensuring that the material discharge work can be carried out normally.

When an opening appears between the limit baffle 17 and the bottom of the guide hopper 16, the functional plastic masterbatch can fall from the guide hopper 16, and then flow along the wedge-shaped guide plate 20 to the discharge port 21 to fall out for discharge, thereby realizing periodic discharge, avoiding all falling in at once to form accumulation again, and further improving the adaptability of use.

[0029] Working principle: The vibrating feeding device in the prior art can quickly feed materials through the cooperation of internal vibration and external vibration, but it uses the first spring to cooperate with the slide bar to push the screen to achieve reciprocating sliding, and it moves relatively on a horizontal plane. The functional plastic masterbatch accumulates on the screen, and a part of the functional plastic masterbatch at the bottom may be attached to the screen, which will cause it to move with the left and right movement of the screen and always attach to the screen. As more and more of it is attached, it is easy to cause the screen to be blocked, affecting the feeding. When working, when screening before feeding, a feeding port 21 is opened at the top of the feeding box 1, and the corresponding functional plastic masterbatch is put into the feeding box 1, and then the active pulley 9 rotates to drive the rotating shaft 1 2 starts to rotate, the rotating shaft 12 drives the spiral guide plate 13 to start rotating to guide the material, so as to avoid excessive accumulation of functional plastic masterbatch. In addition, the driving pulley 9 rotates and drives the driven pulley 10 to start rotating through the belt, and the driven pulley 10 rotates to drive the worm 11 to rotate, and the worm 11 drives the worm wheel 8 to rotate, thereby driving the middle reciprocating screw 7 to rotate, and the middle reciprocating screw 7 rotates in coordination with the large gear 6 and the small gear 5 to drive the two rotating shafts 3 to rotate, so as to realize the rotation of the three-leaf cam 4, and beat the elastic screen plate 2, so that the functional plastic masterbatch attached to its surface can be ejected and then fall from the elastic screen plate 2.

At the same time, a spiral guide plate 13 is set The elastic screening plate 2 is guided to avoid serious accumulation and blockage, so as to ensure normal material unloading. The motor frame 14 supports the installation of the motor 15. When the motor 15 is working, the output shaft drives the active pulley 9 to rotate, so as to realize the rotation of the rotating shaft 12 and the worm 11. In addition, two rotating shafts 3 are provided to cooperate with two small gears 5, which are meshed with the large gear 6 to rotate the two rotating shafts 3, thereby driving the two three-leaf cams 4 to continuously guide the elastic screening plate 2, accelerate the beating frequency of the functional plastic masterbatch, and make the unloading smoother. The guide hopper 16 collects the functional plastic masterbatch after screening, and the central reciprocating screw 7 drives the movable connecting plate 18 to slide back and forth, driving the limit baffle 17 to slide back and forth on the guide hopper 16. When the limit baffle 1 7 and when an opening appears at the bottom of the guide hopper 16, the functional plastic masterbatch can fall from the guide hopper 16, and then flow along the wedge-shaped guide plate 20 to the discharge port 21 to fall out for discharge, thereby realizing periodic discharge and avoiding all falling in at once to form accumulation again, further improving the adaptability of use. By setting an elastic screen plate 2 for screening, and having a certain elastic force at the same time, the rotating shaft 3 can cooperate with the three-leaf cam 4 to beat the elastic screen plate 2 when rotating, so that the functional plastic masterbatch attached to its surface can be ejected and then fall from the elastic screen plate 2.
