Description

Technical Field

[0001] This utility model relates to the technical field of color masterbatch screening equipment, specifically to a multi-stage color masterbatch screening machine. Background Technology

[0002] Screening is a crucial step in the production of color masterbatch, as it removes substandard masterbatch and ensures product quality.

[0003] Some existing screening machines use a simple direct-fall feeding method, where color masterbatch falls freely onto the screen. The impact force causes significant damage to the screen, greatly shortening its service life, increasing maintenance costs, and potentially causing some color masterbatch to break under the impact, producing powdery substances that affect the particle size distribution and overall quality of the product.

A buffer pad is attached to the surface of the V-shaped dispersing plate. A fan is bolted to the side surface of the casing, and a filter screen is installed at the air inlet of the fan. The fan is connected to an air outlet through an air duct, and the air outlet is installed through the side surface of the feed hopper and is inclined downwards at a 30° angle to the horizontal direction.

[0006] Furthermore, the surface of the screen is fixed with speed bumps by bolts, and the speed bumps are long strips with a semi-circular cross-sectional shape. The speed bumps are evenly spaced along the length of the screen.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0019] According to an embodiment of the present invention, a multi-stage screening machine for color masterbatch is provided.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a multi-stage screening masterbatch screening machine according to an embodiment of the present invention includes a casing 1. A feed hopper 2 is welded to the upper surface of the casing 1, and a feed inlet is provided on the upper surface of the feed hopper 2. A screen 3 is bolted to the inside of the casing 1. A discharge hopper 4 for use with the screen 3 is installed on the side surface of the casing 1, and a discharge inlet is provided on the lower surface of the discharge hopper 4. A V-shaped dispersing plate 5 is installed inside the feed hopper 2, with the opening of the V-shaped dispersing plate 5 facing downwards, and a buffer pad 15 is attached to the surface of the V-shaped dispersing plate 5. A fan 6 is bolted to the side surface of the casing 1, and a filter screen is installed at the air inlet of the fan 6. The blower 6 is connected to the air outlet 8 through the air duct 7, and the air outlet 8 is installed through the side surface of the feed hopper 2. The air outlet 8 is inclined downward at a 30° angle to the horizontal direction. The V-shaped dispersion plate 5 receives the falling material through the downward opening structure. With the surface buffer pad 15, the material is first dispersed by physical contact to offset part of the impact force. In addition, the air jet from the 30° inclined air outlet 8 further slows down the falling speed of the material from the side, preventing the masterbatch from being broken due to high-speed impact on the screen 3. The buffer design greatly reduces the direct impact of the material on the screen 3, extends the service life of the screen 3, and reduces the frequency of replacement and maintenance costs.

[0021] Please refer to Figure 1-4The surface of the screen 3 is fixed with speed reduction belts 9 by bolts. The speed reduction belts 9 are long and strip-shaped with a semi-circular cross-section. The speed reduction belts 9 are evenly distributed along the length of the screen 3. The semi-circular speed reduction belts 9 on the surface of the screen 3 are evenly distributed along the length, which can slow down the sliding speed of the masterbatch on the screen 3, avoid insufficient screening caused by the rapid sliding of materials, allow small-diameter particles to have enough time to pass through the mesh, and accurately intercept large-diameter particles, reducing the mixing of particles of different diameters.

[0022] Please refer to Figure 1-4 An airflow regulating valve 14 is connected in series on the surface of the air duct 7, which allows the operator to adjust the jet pressure according to the specific gravity of the material.

[0023] Please refer to Figure 1-4 The screen 3 has multiple layers, and the mesh size of the multi-layer screen 3 decreases from top to bottom, which can realize one-time grading of "coarse sieve-medium sieve-fine sieve". It can separate qualified masterbatch of various particle sizes at the same time without repeated sieving, thus improving grading efficiency.

[0024] Please refer to Figure 1-4 An electromagnetic vibrator 10 is bolted to the lower surface of the casing 1 to provide a vibration power source for the screening of color masterbatch.

[0025] Please refer to Figure 1-4 An organic cover 11 is installed on the upper surface of the chassis 1 to reduce the overflow of masterbatch powder and pollution of the workshop environment.

[0026] Please refer to Figure 1-4 A waste discharge pipe 13 is installed on the lower surface of the casing 1, and a butterfly valve is connected in series on the surface of the waste discharge pipe 13 so as to discharge the masterbatch powder from the waste discharge pipe 13.

[0027] Please refer to Figure 1-4 An integrated controller 12 is installed on the side surface of the feed hopper 2. The integrated controller 12 can centrally manage the operating parameters of the fan 6 and the electromagnetic vibrator 10, making it convenient for operators to adjust them in real time.

[0028] Working principle: After the masterbatch is fed into the feed inlet of the feed hopper 2, it first falls into the downward-facing V-shaped dispersing plate 5. The V-shaped structure utilizes the guiding characteristics of the inclined plane to evenly distribute the originally concentrated falling material to both sides, avoiding local accumulation of material on the screen 3; at the same time, the buffer pad 15 attached to the surface of the V-shaped dispersing plate 5 is in direct contact with the material, absorbing the impact force of the falling material through elastic deformation, initially reducing the material speed, and preventing the masterbatch from breaking due to high-speed impact on the screen 3. After the fan 6 on the side surface of the casing 1 is started, the outside air is purified by the filter screen of the air inlet and then transported to the air outlet 8 through the air duct 7. The air outlet 8 is tilted downward at a 30° angle to the horizontal direction, spraying low-pressure airflow into the feed hopper 2. The "horizontal inward component" of the airflow forms lateral resistance to the falling material, further slowing down the falling speed of the material. Together with the V-shaped dispersion plate 5, it achieves "double buffering". After the electromagnetic vibrator 10 on the lower surface of the machine box 1 is powered on, it generates high-frequency micro-amplitude vibration. The vibration energy is transmitted to the multi-layer screen 3 inside the machine box 1, causing the screen 3 to vibrate up and down. This vibration causes the masterbatch on screen 3 to continuously tumble and slide, accelerating the passage of small-diameter particles through the screen openings, while simultaneously pushing large-diameter particles towards the discharge bin 4 at the end of screen 3. Screen 3 is arranged in multiple layers along the height of the machine housing 1, with the mesh size gradually decreasing from top to bottom, forming a grading process of "coarse screening → medium screening → fine screening". Semi-circular long strip deceleration belts 9 are fixed at equal intervals along the length of the surface of each layer of screen 3. When the masterbatch slides on screen 3, the deceleration belts 9 will block the material movement, prolonging the residence time of the material on the surface of screen 3, providing more time for small-diameter particles to pass through. The sieve holes reduce the phenomenon of "missing the sieve" and prevent the material from sliding quickly through the sieve 3 due to vibration, resulting in insufficient screening. This improves the separation accuracy of color masterbatch of different particle sizes and reduces the probability of mixing. Each layer of sieve 3 has a discharge bin 4 installed on the side surface of the machine box 1. The qualified color masterbatch after being screened by the sieve 3 enters the discharge bin 4 under the action of vibration and is finally discharged from the discharge port. It can be directly connected to the subsequent packaging or production process. The tiny powder that passes through the bottom sieve 3 falls into the bottom of the machine box 1. The operator can periodically open the butterfly valve on the surface of the waste discharge pipe 13 to discharge the waste from the waste discharge pipe 13 for centralized treatment.
