Technical Field

[0001] The invention relates to the technical field of masterbatch processing, and in particular to a layered masterbatch processing dryer. Background Art

[0002] Masterbatch is a mixture of resin and a large amount of pigment or dye with high concentration of color. Masterbatch, also known as color seed, is an aggregate made by uniformly loading an abnormal amount of pigment or dye in resin. Masterbatch needs to be dried in a dryer during the production process. Most existing dryers pile up the masterbatch uniformly inside during the drying process, and rely on internal temperature and stirring to dry the masterbatch. However, it is not only easy to make the masterbatch heat unevenly, but also the masterbatch piled in the middle of the interior is more difficult to be well dried, resulting in low drying effect and efficiency of the masterbatch. Therefore, a layered masterbatch processing dryer is urgently needed. Summary of the invention

In this process, the spring 7-7 can drive the several side plates 6 and the several partitions 5 to move synchronously through the movable block 7-6, the driving rod 7-2 and the slider 7-1. At the same time, through the reciprocating expansion and contraction of the spring 7-7, the partition 5 can also drive the masterbatch to produce a larger vibration frequency, thereby improving the turning efficiency of the masterbatch; The adjustable driving mechanism 9 comprises: A driving disk 9-1, wherein the driving disk 9-1 is fixedly arranged on the output shaft of the driving motor 8, a connecting rod 9-2 is screwed on the driving disk 9-1 through a shaft and a bearing, a micro-control motor 9-3 is fixedly arranged on the connecting rod 9-2, a threaded rod 9-4 is fixedly arranged on the output shaft of the micro-control motor 9-3, and the threaded rod 9-4 is screwed and penetrated on the connecting rod 9-2 through a bearing; The second connecting rod 9-5 is screwed on the side wall of the driving frame 7-4 through an axis and a bearing, one end of the threaded rod 9-4 is screwed on the second connecting rod 9-5 through a thread, one end of the first connecting rod 9-2 is fixed with two second guide rods 9-6 by bolts, and the second guide rod 9-6 is movably inserted on the second connecting rod 9-5.

[0024] Example 2: See Figure 1 , Figure 2 and Figure 6As shown, it is further improved on the basis of embodiment 1, the upper barrel 2 is fixedly provided with a support frame 15 by bolts, the support frame 15 is fixedly provided with a servo motor 16 by bolts, the lower part of the support frame 15 is provided with a screw rod 17 by a bearing, the spiral part of the screw rod 17 is movably arranged in the lower opening of the upper barrel 2, the output shaft of the servo motor 16 is fixedly connected with the screw rod 17, the servo motor 16 can drive the screw rod 17 to rotate, and can adjust the rotation speed of the screw rod 17 according to the demand, and realize the uniform speed in the drying box 1. Loading can not only avoid a large amount of masterbatch accumulation on the uppermost partition 5 due to too fast loading speed, but also avoid the masterbatch being blocked in the loading barrel 2 during the loading process. A guide plate 18 with a downward tilt on the left side is fixed by bolts at a position below the loading barrel 2 inside the drying box 1, and the guide plate 18 is arranged in a downward tilted structure on both the front and rear sides. The guide plate 18 can provide guidance for the masterbatch falling from the loading barrel 2, so that the masterbatch can be more evenly distributed to the left side of the upper part of the upper partition 5.

[0025] When using the present invention, the heating fan 3 is started to preheat the inside of the drying box 1. After the temperature inside the drying box 1 reaches the standard, the masterbatch is poured into the upper barrel 2, and then the servo motor 16 can be started. The servo motor 16 drives the screw rod 17 to rotate, so that the masterbatch in the upper barrel 2 can fall into the drying box 1 at a uniform speed, and through the material guiding effect of the guide plate 18, the masterbatch can be spread more evenly on the left side of the upper partition 5; Then start the driving motor 8, the driving motor 8 drives the driving disk 9-1 to rotate, and the driving disk 9-1 cooperates with the No. 1 connecting rod 9-2, the threaded rod 9-4 and the No. 2 connecting rod 9-5 to make the driving frame 7-4 reciprocate up and down, and the driving frame 7-4 drives the linkage rod 7-5 to reciprocate up and down through the connecting rod 7-3, and the linkage rod 7-5 drives the driving rod 7-2 to reciprocate up and down through the spring 7-7 and the movable block 7-6. The driving rod 7-2 drives the side plate 6 to swing back and forth through the slider 7-1, and in this process the slider 7-1 will also slide in the slide groove 10, and the partition plate 5 can swing back and forth with the side plate 6, thereby driving the masterbatch to vibrate and flip, and make the masterbatch gradually move toward the inclined direction of the partition plate 5, which not only realizes the slow transportation of the masterbatch in the drying box 1, but also realizes the all-round drying of the masterbatch. At the same time, the spring 7-7 will also deform and release elastic potential energy during the force process, thereby increasing the vibration frequency of the masterbatch; When it is necessary to adjust the drying time of the masterbatch in the drying box 1, the threaded rod 9-4 can be driven to rotate by the micro-control motor 9-3, and under the guidance of the No. 2 guide rod 9-6, the distance between the No. 1 connecting rod 9-2 and the No. 2 connecting rod 9-5 is changed, so that the height of the driving frame 7-4, the connecting rod 7-3 and the linkage rod 7-5 when they move up and down reciprocatingly can be adjusted, and the inclination angle of the side plate 6 and the partition 5 is changed. The larger the inclination angle of the partition 5, the faster the movement speed of the masterbatch when vibrating on the partition 5, so that the drying time of the masterbatch in the drying box 1 is also shorter. Conversely, the smaller the inclination angle of the partition 5, the slower the movement speed of the masterbatch when vibrating on the partition 5, so that the drying time of the masterbatch in the drying box 1 is also longer.

[0026] Compared with the prior art, the beneficial effects of this specific implementation are as follows: 1. Through the cooperation of the side plate 6, the synchronous linkage mechanism 7, the drive motor 8 and the adjustable drive mechanism 9, the masterbatch can be laid on the upper part of the plurality of partitions 5 in a relatively uniform and dispersed manner during the drying process, and the masterbatch can also be moved slowly and vibrated and turned over, thereby avoiding the accumulation of the masterbatch and realizing the omnidirectional drying of the masterbatch, thereby improving the drying efficiency and effect of the masterbatch; 2. Through the cooperation of the support frame 15, the servo motor 16 and the screw rod 17, the loading cylinder 2 can load the drying box 1 at a uniform speed according to the use requirements, so as to avoid the accumulation of too much masterbatch on the partition 5; 3. By rotating the threaded rod 9-4, the distance between the No. 1 connecting rod 9-2 and the No. 2 connecting rod 9-5 can be adjusted, so that during the rotation of the driving disk 9-1, the up and down reciprocating movement range of the driving frame 7-4 can be changed to adjust the vibration amplitude of the masterbatch on the partition 5.

[0027] The above description is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
