Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and specifically to a plastic particle screening device. Background Technology

[0002] In the field of plastic granule screening, existing screening devices typically use vibrating screens in conjunction with sieves to classify plastic granules. However, in practical applications, plastic granules are prone to localized accumulation or concentrated discharge during the feeding process, resulting in uneven distribution of granules on the sieve. This uneven material distribution not only reduces screening efficiency but also affects screening accuracy, failing to meet the requirements of high-efficiency and high-precision production.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a plastic particle screening device that can effectively solve the above-mentioned technical problems.

[0028] like Figures 1 to 9 As shown, this utility model relates to a plastic particle screening device, comprising:

[0029] The support frame 1 and the machine platform 17 are set on the top of the support frame 1. The top of the machine platform 17 has a screening cavity, and a screen 2 is installed in the screening cavity. The screen 2 can effectively classify plastic particles of different sizes, thereby realizing the separation of large particles and small particles of the material.

[0030] A vibration motor 5 is installed at the bottom of the machine base 17. When the vibration motor 5 is working, it drives the machine base 17 to vibrate as a whole, so that the plastic particles are continuously conveyed from the feeding side to the unloading side on the screen 2.

[0031] On the feeding side of the machine 17, a first feeding port 3 and a second feeding port 4 are arranged sequentially from top to bottom. The first feeding port 3 and the second feeding port 4 can respectively discharge large particles and small particles, ensuring that the graded materials can be discharged in an orderly manner. The second feeding port 4 is generally arc-shaped, and forms a buffer slope and a feeding trough sequentially from top to bottom. This can slow down the falling speed of the particles, avoid the accumulation of materials due to concentrated impact, and guide small particles smoothly into the feeding trough, improving the smoothness of discharge.

[0032] A material-pushing plate 14 is rotatably installed at the bottom of the discharge side of the feeding trough; a U-shaped connecting rod 12 is also installed on the side wall of the feeding trough, the U-shaped connecting rod 12 is located below the material-pushing plate 14, and a first spring 13 is provided between the U-shaped connecting rod 12 and the material-pushing plate 14; the material-pushing plate 14 can reciprocate under the vibration of the machine base 17, and further amplify the swing amplitude in conjunction with the first spring 13, so that the plastic particles discharged from the second feeding port 4 can be repeatedly scattered, thereby avoiding the accumulation of small plastic particles near the feeding port and achieving uniform feeding of small plastic particles.

[0033] When the vibrating motor 5 is working, it drives the machine platform 17 to vibrate as a whole, so that the plastic particles entering the screening cavity move continuously on the surface of the screen 2 and are classified. Large plastic particles are guided to the first discharge port 3 for discharge, while small plastic particles fall into the second discharge port 4 through the screen 2. At the same time, the material guide plate 14 set at the bottom of the discharge trough oscillates periodically under the action of vibration, and further amplifies the oscillation amplitude with the cooperation of the first spring 13, so that the plastic particles discharged from the second discharge port 4 are repeatedly thrown during the discharge process, effectively avoiding material accumulation and ensuring uniform feeding and continuous conveying of small particles.

[0034] A connecting plate 22 is installed horizontally outward on the feeding side of the machine platform 17. A connecting column 8 is installed on the top of the connecting plate 22 along the width direction of the machine platform 17. When there is one connecting column 8, it is located in the middle of the width direction of the machine platform 17. When there are at least two connecting columns 8, they are symmetrically arranged along the width direction of the machine platform 17. A sliding column 9 is slidably connected to the top of the connecting column 8. A second spring 15 is provided between the connecting column 8 and the sliding column 9, so that the sliding column 9 and the connecting column 8 can slide relative to each other. The elastic force of the second spring 15 plays a buffering role or amplifies the swing of the connecting plate 22, thereby increasing the swing amplitude of the feeding plate 6 during the vibration process, so that the material can be effectively scattered.

[0035] The top of the sliding column 9 is hinged to a second hinge rod 10, and the top of the second hinge rod 10 is hinged to a feeding plate 6; the feeding plate 6 is used for feeding; the feeding plate 6 includes a first gentle slope and a first ramp connected to the first gentle slope, and baffles are set on the side walls of the first gentle slope and the first ramp; the first gentle slope is used to receive plastic granules, and the first ramp facilitates the falling of plastic granules.

[0036] The bottom of the feeding plate 6 is connected to a telescopic rod 11, and the bottom end of the telescopic rod 11 is fixedly connected to the connecting plate 22; a third spring 16 is provided inside the telescopic rod 11, so that the telescopic plate can extend, retract and return to its original position.

[0037] After the plastic granules enter the feeding plate 6, the feeding plate 6 swings under the vibration of the machine platform 17, causing the plastic granules to be repeatedly thrown back and forth along the conveying direction by the feeding plate 6. This makes the granules more evenly distributed when they enter the screen 2, avoiding excessive accumulation in a certain area and improving screening efficiency. At the same time, the periodic throwing action of the feeding plate 6 is equivalent to pre-dispersing the material, making the material fall onto the screen 2 in a looser state, thereby speeding up the speed at which the granules pass through the screen 2.

[0038] A third hinge rod 18 is hinged to the side wall at the bottom of the feeding plate 6. A fourth hinge rod 19 is hinged to the bottom end of the third hinge rod 18. An anti-blocking rod 20 is hinged to the bottom end of the fourth hinge rod 19. The other end of the anti-blocking rod 20 is hinged to the unloading side of the machine base 17 and located below the screen 2. The fourth hinge rod 19 passes through both sides of the screen 2, and the screen 2 limits the movement of the fourth hinge rod 19. A pin 21 is installed on the top of the anti-blocking rod 20. The pin 21 is intermittently inserted into the holes of the screen 2 to prevent the screen 2 from clogging. When the feeding plate 6 swings, it drives the anti-blocking rod 20 to swing, thereby causing the pin 21 to intermittently insert into the holes of the screen 2 to avoid clogging by plastic particles. In addition, the stroke of the anti-blocking rod 20 can be adjusted by adjusting the length of the third hinge rod 18 and the fourth hinge rod 19. The anti-blocking rod 20 can also be driven by an independent motor.
