Description

Technical Field

[0001] This utility model relates to the technical field of color masterbatch particle sorting equipment, and in particular to a color masterbatch particle sorting device that facilitates the production of color masterbatch. Background Technology

[0002] Color masterbatch is a colorant for polymer materials. It contains coloring materials such as dyes. By adding color masterbatch in plastic manufacturing, the color of the finished plastic product can be adjusted.

[0003] Color masterbatch is produced by screw extruder through stranding and then pelletizing. The color masterbatch also needs to undergo pellet sorting. A sorting device separates and collects particles of different sizes. The color masterbatch moves on a screen to achieve sorting. During the sorting process, the color masterbatch near the feed inlet is more concentrated, with fewer particles on the sides and more particles in the middle. This causes smaller color masterbatch to flow above the larger particles, preventing them from passing through the screen downwards. This results in smaller particles being mixed with larger particles, necessitating the control of the color masterbatch flow rate during the sorting equipment operation, thus reducing work efficiency. Utility Model Content

[0004] This disclosure relates to a color masterbatch particle sorting device that facilitates the production of color masterbatch. A spiral feeding shaft guides the color masterbatch particles to be spread horizontally, increasing the area of ​​the color masterbatch particles. The color masterbatch particles are displaced towards the areas with lower thickness, resulting in a more uniform thickness of the color masterbatch particles. The device also fills in areas with fewer color masterbatch particles, increasing the contact area between the color masterbatch particles and the screen of the upper screening frame. This allows for a larger flow rate of color masterbatch particles, accelerating the sorting speed and efficiency of the color masterbatch particles and preventing the mixing of small color masterbatch particles with large color masterbatch particles.

[0005] In a first aspect, this disclosure provides a color masterbatch particle sorting device for easy color masterbatch production, specifically including: an upper screening frame, a lower screening frame, and an upper fan housing.

[0006] In at least some embodiments, the drive motor shaft and the spiral material distribution shaft are fixedly connected or connected via a reducer. The spiral material distribution shaft is located below and behind the upper discharge funnel. The spiral protrusion structure on the outside of the spiral material distribution shaft guides the color masterbatch particles to move horizontally axially.

[0007] In at least some embodiments, a buffer spring is fixedly installed at the bottom of the lower screening frame, the lower end of the buffer spring is fixedly connected to the lower base, and a vibration motor is fixedly installed at the bottom of the lower screening frame.

[0008] In at least some embodiments, the side air outlet of the upper fan housing is connected to and fixed with a corrugated connecting pipe, the interior of the upper fan housing is rotatably equipped with an internal rotating fan, the bottom of the upper fan housing is fixed with a central motor, the bottom of the central motor is fixed with a lower fan housing, a PTC electric heating element is provided on the inner side of the air outlet of the upper fan housing, and an air inlet is opened on the top of the upper fan housing.

[0012] This utility model provides a color masterbatch particle sorting device that facilitates the production of color masterbatch, and has the following beneficial effects:

[0013] The spiral material distribution shaft guides the color masterbatch granules to spread horizontally, increasing their surface area. The granules shift towards areas with lower thickness, resulting in a more uniform thickness. It also fills areas with fewer granules, increasing the contact area between the granules and the upper screening frame screen.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes a color masterbatch particle sorting device for easy color masterbatch production, comprising: an upper screening frame 1, a lower screening frame 2, and an upper fan housing 3. An upper discharge funnel 101 is fixed to the top of the first end of the upper screening frame 1. A spiral material distribution shaft 102 is rotatably mounted on the inner side of the first end section of the upper screening frame 1. A drive motor 103 is fixedly mounted on the outer side of the upper screening frame 1. The lower screening frame 2 is bolted to the lower part of the upper screening frame 1. A buffer spring is fixedly mounted at the bottom of the lower screening frame 2. 201, the lower end of the buffer spring 201 is fixedly connected to the lower base 203, a vibrating motor 202 is fixedly installed at the bottom of the lower screening frame 2, the first end of the upper screening frame 1 is connected to the upper fan housing 3, a corrugated connecting pipe 301 is fixedly connected to the side air outlet of the upper fan housing 3, an inner rotating fan 302 is rotatably installed inside the upper fan housing 3, a middle motor 303 is fixed at the bottom of the upper fan housing 3, and a lower fan housing 304 is fixed at the bottom of the middle motor 303. A PTC electric heating element 305 is installed inside the air outlet of the upper fan housing 3. An air inlet 306 is opened on the top of the upper fan housing 3. An internal rotating fan 302 is rotatably installed inside the lower fan housing 304. A corrugated connecting pipe 301 is fixedly connected to the air outlet on the side of the lower fan housing 304. The PTC electric heating element 305 is installed inside the air outlet of the lower fan housing 304 to heat the air outlet of the internal rotating fan 302. The corrugated connecting pipe 301 of body 3 is connected and fixed to the upper screening frame 1. The corrugated connecting pipe 301 of the lower fan box 304 is connected and fixed to the lower screening frame 2. The lower fan box 304 and the lower base 203 are fixedly connected. The upper fan box 3 discharges air to the upper screening frame 1. The PTC electric heating element 305 is energized to heat the air. The hot air plays an auxiliary drying role for the color masterbatch particles in the upper screening frame 1, reducing the moisture in the color masterbatch particles in the upper screening frame 1.

[0031] In this embodiment, the drive motor 103's rotating shaft and the spiral material distribution shaft 102 are fixedly connected or connected via a reducer. The spiral material distribution shaft 102 is located below and behind the upper unloading funnel 101. The spiral protrusion structure on the outside of the spiral material distribution shaft 102 guides the color masterbatch particles to move horizontally and axially, guiding the color masterbatch particles to spread. The color masterbatch particles shift towards the position with lower thickness, making the thickness of the color masterbatch particles more uniform, expanding the contact surface between the color masterbatch particles and the screen of the upper screening frame 1, accelerating the speed at which the color masterbatch particles pass through the screen of the upper screening frame 1, and accelerating the classification speed and efficiency of the color masterbatch particles.

[0032] In this embodiment, the main shaft of the motor 303 is fixed to the inner fan 302 of the upper and lower fan housings 3 and 304 respectively. The bottom of the lower fan housing 304 is provided with an air inlet 306. The corrugated connecting pipe 301 of the lower fan housing 304 is connected to and fixed to the lower screening frame 2. The lower fan housing 304 exhausts air towards the lower screening frame 2. The PTC electric heating element 305 is energized to heat the exhaust air. The hot air plays an auxiliary drying role for the color masterbatch particles in the lower screening frame 2, reducing the moisture in the color masterbatch particles in the lower screening frame 2.

[0033] In Example 2, based on Example 1, the upper screening frame 1 and the upper unloading funnel 101 are bolt-fixed and detachable structures. Another upper screening frame 1 can be added to the top of the upper screening frame 1. The filter holes of the two upper screening frames 1 are reduced by one level from top to bottom to achieve triple particle classification, further increase the classification level of color masterbatch particles, and make the classification of color masterbatch particles more refined.

[0034] The working principle of this embodiment is as follows: Color masterbatch cut into granules is conveyed to the upper discharge funnel 101. The granules inside the upper discharge funnel 101 fall into the upper screening frame 1. The middle part of the upper screening frame 1 is a screen. Larger color masterbatch granules remain in the upper screening frame 1, while smaller color masterbatch granules pass through the screen in the middle of the upper screening frame 1 and fall into the lower screening frame 2, thus achieving the classification of color masterbatch granules of two sizes. The vibration motor 202 drives the lower screening frame 2 and the upper screening frame 1 to vibrate synchronously. The vibration accelerates the speed at which the color masterbatch granules pass through the screen in the middle of the upper screening frame 1 and accelerates the movement speed of the color masterbatch granules inside the lower screening frame 2 and the upper screening frame 1. The lower base 203 contacts the ground, and the buffer spring 201 blocks and reduces the vibration transmission from the lower screening frame 2 to the lower base 203. The color masterbatch granules in the upper discharge funnel 101 fall into the upper discharge funnel 101. If the color masterbatch granules are relatively concentrated... At this time, the color masterbatch particles at the higher position will contact the spiral material distribution shaft 102. The drive motor 103 drives the spiral material distribution shaft 102 to rotate in a circumferential direction. The spiral protrusion structure on the outside of the spiral material distribution shaft 102 guides the color masterbatch particles to move horizontally and axially, guiding the color masterbatch particles to spread. The thickness of the color masterbatch particles decreases, and the color masterbatch particles move towards the position with lower thickness, making the thickness of the color masterbatch particles more uniform. The displacement and filling of the position with fewer color masterbatch particles expands the area of ​​the color masterbatch particles, allowing a larger flow of color masterbatch particles to pass through. This expands the contact surface between the color masterbatch particles and the screen of the upper screening frame 1, speeds up the speed at which the color masterbatch particles pass through the screen of the upper screening frame 1, speeds up the classification speed and efficiency of the color masterbatch particles, and avoids the situation where color masterbatch particles gather together, with small particles following large particles, or small particles bypassing the screen and still mixing with large particles, thus reducing the situation where small particles are mixed with large particles.

[0035] The central motor 303 drives the inner rotating fan 302 to rotate, and the rotation of the inner rotating fan 302 generates air. The upper fan housing 3 and the lower fan housing 304 output air to the upper screening frame 1 and the lower screening frame 2. The PTC electric heating element 305 is energized to heat the air. The hot air plays an auxiliary role in drying the masterbatch particles, reducing the moisture in the masterbatch particles. The dust in the masterbatch particles can also be carried away by the wind, achieving a cleaning effect. The corrugated connecting pipe 301 can expand and contract, and the corrugated connecting pipe 301 adapts to the positional changes when the upper screening frame 1 and the lower screening frame 2 vibrate.
