Description

Technical Field

[0001] The utility model belongs to the field of masterbatch detection, and particularly relates to a tablet pressing mechanism for masterbatch detection. Background Technique

[0002] The masterbatch is fully called plastic masterbatch, which is composed of an excessive amount of chemical additives, carrier resin, dispersant, etc. The colored masterbatch is usually an aggregate obtained by uniformly loading an excessive amount of pigment on the resin.

[0003] In the production of masterbatch, due to factors such as equipment and environment, impurities often mix into the masterbatch during the production process, thus affecting the quality of the masterbatch. In the prior art, there are relatively few methods for detecting impurities in masterbatch. Generally, the masterbatch is sliced or pressed into tablets to observe the impurities on its surface and inside.

[0004] For example, the application number CN202321051265.5 discloses a tablet pressing mechanism for detecting impurities in masterbatch. The mechanism includes an upper die, a heating plate, a bottom plate, and a detection module. The masterbatch is placed on the bottom plate. The upper die drives the heating plate to move downward, making the heating plate gradually approach the bottom plate, applying pressure to the masterbatch, and pressing the masterbatch into a thin sheet. The detection module detects the thin sheet. In actual application, the masterbatch needs to be in a high-temperature state when being pressed into a tablet, so that the surface of the formed tablet-shaped masterbatch will be smoother and the detection accuracy will be higher. However, in the above scheme, the bottom plate does not have a heating function, and the forming effect at the bottom is poor during downward pressing, the surface is rough, and the detection error is large.
