Description

Sample bottle cap screwing machine and cap screwing device for same

Technical Field

The utility model relates to the collection system equipment field of material sample, concretely relates to spiral cover device and a kind of sample bottle spiral cover machine that sample bottle spiral cover machine was used.

Background

For sampling, sampling and testing of material (such as ore and coal) samples, each country has a mandatory standard, and sampling and testing of the samples must be carried out according to the standard. The sampling, sample preparation and testing process of the sample has the principle that the granularity and the mass of the collected sample are gradually reduced on the premise of not destroying the representativeness of the sample until the granularity and the mass (weight) precision requirements of the sample in laboratory testing are met, and then the sample meeting the requirements is subjected to relevant testing analysis.

Taking the sampling and preparation of coal as an example, the sampling and preparation process is actually a sampling and analyzing process, and the purpose of sampling and preparation of coal is to obtain an experimental coal sample of which the experimental result can represent the whole batch of sampled coal. Coal is an uneven substance (granularity, mass characteristic distribution and the like), the mass of sampled coal is generally large (dozens of tons to tens of thousands of tons), the process of sampling a representative part of coal from the sampled coal is called as sampling, and at present, various methods such as mechanical sampling, manual sampling, semi-mechanical sampling and the like are provided. After the sample is collected according to the standard, the next process is 'sample preparation', and the sample preparation process generally comprises the processes of crushing, mixing, division, drying and the like. After the sample is prepared, the next sample 'test' is developed, and the sample is analyzed. Whether "sampling", "sample preparation" or "assay", there is no loss of sample during this process, and no physical or chemical changes to the sample that would affect the final test results.

In the sampling, sample preparation and assay work of material (such as ore and coal) samples, sample bottles filled with the samples (coal samples) need to be sealed and then stored or transported to the next link, and the process needs to use a sample bottle cap screwing machine to carry out cap screwing operation on the sample bottles. The existing sample bottle cap screwing machine comprises a rotary driving mechanism and a rotary punch (cap screwing head), and the cap screwing head is driven by the rotary driving mechanism to descend and then contacts with a sample bottle and a bottle cap and rotates to achieve the purpose of cap screwing. The following technical problems exist:

1. some existing rotary punches can not be self-locked, a mechanical arm clamping sample cover with power is adopted to transmit torque to screw the cover, the clamping force of the sample cover is kept by utilizing the power, and the scheme has the defects that extra power needs to be provided, the reliability of the torque of the screw cover is ensured, but the cost is high, the control is complex, and the manufacture and the maintenance are not easy.

2. Part of the existing rotary punch adopts a cap screwing head to directly press on a sample cap, and torque is transmitted by using the friction force between the cap screwing head and the top surface of the sample cap to screw the cap, so that the scheme has the defects that the transmission is unreliable due to the influence of pressure and friction factors on the cap screwing torque; on the other hand, when the cap is screwed, the pressure generally requires to be higher to transmit proper torque to ensure that the cap is screwed reliably, but the thread pair is easily abraded and damaged by overlarge pressure, so that the sample bottle is not recycled.
