Description

Technical Field

[0001] The invention belongs to the technical field of masterbatch sampling, and in particular relates to an improved sampling device for masterbatch detection. Background Art

[0002] Masterbatch is a plastic processing aid, mainly used in the plastic processing and molding process. Masterbatch is a granular material made by mixing various additives, fillers and a small amount of carrier resin, and then processed by extruders and other equipment. At present, in the production process of masterbatch, it is usually necessary to use sampling equipment to sample the masterbatch for subsequent testing;

[0003] The currently existing application number is 202420214535.8, which is a sampling device for masterbatch detection, comprising a control tube, a sampling assembly is provided inside the control tube, a plug is threadedly connected to the bottom of the control tube, an auxiliary assembly is provided on the back of the control tube, and the sampling assembly comprises a sampling rod provided inside the control tube, a slot is provided on the surface of the sampling rod, and the sampling device for masterbatch detection pushes out the sampling box by pushing and pulling the rod, and a spring and a shrapnel are also provided inside the sampling device. After repeated use for a long time, the shrapnel and the spring are prone to fatigue, resulting in reduced elasticity. After the sampling is completed, when the sampling box is still open, as the control tube is drawn out, when the sampling box is not filled or there is still a certain gap, the plastic particles in the removal process may enter the sampling box, affecting the accuracy of the sampled sample;

[0004] And the existing application number is 202322717708.6, which is a sampling device for masterbatch inspection, including a sampling bucket, a weighing shell and a handle. A weighing shell is welded to one end of the sampling bucket, and a mounting sleeve is welded to one end of the weighing shell. When in use, this masterbatch sampling device can only sample the masterbatch once, and it is not convenient to assemble and splice to sample masterbatch at different positions in the masterbatch tank. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an improved sampling device for masterbatch detection. After sampling is completed, the sampling box can be closed or the opening of the sampling box can be reduced by rotation to prevent masterbatch at non-sampling positions from entering the sampling box during the removal process and destroying the accuracy of the sampled sample. The sampling box can be assembled by splicing, so that masterbatch samples from multiple locations can be collected at the same time.
