Description

Technical Field

[0001] This utility model relates to the field of color masterbatch, and in particular to a drying device suitable for color masterbatch. Background Technology

[0002] Color masterbatch is a new type of special colorant for polymer materials. It is mainly composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by uniformly loading pigment into resin. Its coloring power is higher than that of the pigment itself. During processing, a small amount of color masterbatch is mixed with uncolored resin to achieve the designed pigment concentration in the colored resin or product.

[0003] In the production of color masterbatches, drying equipment is required. For example, Chinese patent CN221368756U discloses a color masterbatch drying and storage cabinet, which includes a cabinet body. Side plates are fixedly connected to both sides of the bottom of the cabinet body, and a partition is fixedly connected to the center of the bottom of the cabinet body. The partition has an internal cavity, and a motor is fixedly installed at the inner bottom of the partition. A drive gear is provided at the upper end of the motor. This color masterbatch drying and storage cabinet, through the design of a motor, drive gear, transmission rod, driven gear, stirring rod, chassis, fan, and heating pipe, uses the combined operation of the fan and heating pipe to generate hot air to dry the stored color masterbatch.

[0004] The aforementioned masterbatch drying equipment has the following drawbacks during use:

[0005] Firstly, the color masterbatch cannot be dried continuously, requiring regular loading and unloading of materials, resulting in high labor intensity;

[0103] Distance sensor module 2 is installed on the feed end of screw conveyor 501 to assist the PLC controller in detecting the quantity of masterbatch.

[0104] Working principle and usage:

[0105] Step 1, Pre-setting:

[0106] Press the start switch to perform a no-load test. Place the unloaded storage cylinder structure into the storage base 103, and then install the frustum-shaped connector 503 onto the discharge end of the screw conveyor 501.

[0107] Place the masterbatch to be dried into storage hopper 201.

[0108] The second step is to use:

[0109] Pressing the drying switch activates the distance sensor module, which outputs a signal to the PLC controller. The PLC controller then outputs signals to the servo motor 202, the electric valve, and the push rod motor 205.

[0110] Servo motor 202 starts, allowing the masterbatch to enter the transition cylinder 204; push rod motor 205 starts after a delay, driving the separator to close the upper end of the transition cylinder 204; electric valve opens after a delay, thereby realizing the quantitative entry of masterbatch.

[0111] The PLC controller outputs a delayed signal to the push rod motor 305 and the stepper motor 306.

[0112] The push rod motor 305 drives the stepper motor 306 to move downwards, causing the distribution plate 307 to move downwards. The stepper motor 306 then drives the distribution plate 307 to rotate, spreading the masterbatch evenly on the screen and improving drying efficiency. At the same time, the screen filters out masterbatch particles with an outer diameter smaller than the screen opening, allowing these masterbatch particles to enter the collection hopper and finally into the screw conveyor 501.

[0113] The PLC controller synchronously outputs signals to the blower 401 and the heating wire 402. The blower 401 and the heating wire 402 start, and under the action of the air tower mechanism, hot air enters the drying seat 102 evenly to carry out the drying work.

[0114] The third step is storage:

[0115] After drying for 30 seconds (adjustable), the PLC controller outputs signals to servo motor 2 (303), servo motor 3 (304), and push rod motor 2 (305).

[0116] Push rod motor 2 305 drives the movable chute to move to the bottom of the unloading pipe trough; servo motor 2 303 and servo motor 304 start after a delay, causing the material tray box 301 to tilt, so that the large particles of masterbatch enter the movable chute and the fixed chute 308, and finally enter the screw conveyor 501.

[0117] When the masterbatch reaches below the distance sensor module 2, the distance sensor module 2 outputs a signal to the PLC controller, and the PLC controller outputs a signal to the screw conveyor 501 and the circulating fan 502; the screw conveyor 501 feeds the masterbatch into the storage drum; the circulating fan 502 starts to dry the environment inside the storage drum in preparation for long-term storage of the masterbatch.

[0118] The two storage cylinders store large-particle masterbatch (target) and other masterbatch (recycled or used as secondary masterbatch) respectively.

[0119] Example 2: Based on Example 1, a protective platform is added, located above the push rod motor 305; the protective platform is truncated cone-shaped.
