Rubber additive production sampling device

Abstract

The invention provides a rubber additive production sampling device. The rubber additive production sampling device comprises a sampling barrel and a pushing block, a sampling head is fixed at one end of the sampling barrel; a through hole A is formed in the material pushing block; when the sampling head is inserted into the through hole A, the material pushing block can be hermetically connected with the sampling head, and the material pushing block can move along the axis direction of the sampling head; a long-strip-shaped groove A is formed in the material pushing block and comprises an M part, an N part and an E part, and the M part, the N part and the E part are sequentially arranged from top to bottom. The N part is communicated with the through hole A. A baffle is arranged in the groove A and can move up and down along the groove A. The sampling device has the advantages of being reasonable in design, high in practicability and convenient to use. By using the sampling device, accurate sampling can be realized, the consistency of the sampling amount of each working procedure is ensured, and the detection accuracy and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of rubber auxiliaries production devices, in particular to a sampling device for rubber auxiliaries production. Background technique [0002] Rubber additives are indispensable raw materials in the production of rubber products, and their properties directly affect the performance of rubber products. Commonly used rubber additives include accelerators, antioxidants, plasticizers, etc., by adding an appropriate amount of additives in the preparation of rubber products. , to produce rubber products with different properties. [0003] The production of rubber additives is carried out in the reaction tank. During the reaction process, it is necessary to sample and test from each process. During the sampling process, the sample weight of each stage needs to be basically the same. Otherwise, the sampled sample will not be representative, which will affect the accuracy and precision of the test. . [0004] At pre...

AI Technical Summary

Problems solved by technology

This kind of suction device mainly has the following problems: First, after the sampling head is inserted into the sampling port, liquid will inevitably adhere to the outer wall, and the liquid will slip when the sampling head is moved, affecting the cleanliness of the environment and causing samples The second is that the negative pressure formed in the piston and the sampling cylinder makes the sample enter the sampling tube, but when the pulling speed changes, the negative pressure environment in the closed space formed by the piston and the sampling cylinder changes, resulting in a change in the sampling accuracy and affecting Consistency of Sample Volume
