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 for kind of sample bottle spiral cover machine.

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 current appearance bottle spiral cover machine includes rotary driving spare and rotatory drift, has following technical problem:

1. part of the existing rotary punch is connected with a rotary driving piece by a magnetic assembly, and the rotary punch is kept to be driven to rotate under the action of magnetic force generated by opposite attraction of an upper magnetic pole and a lower magnetic pole. After the bottle cap is screwed on the bottle mouth, the rotary punch is blocked to stop rotating, and the rotary driving piece is rotationally driven, at the moment, the upper magnetic pole and the lower magnetic pole can relatively slip, the magnetic force generated between the two magnetic poles during the slipping of the cap screwing forms pulse type torsion on the bottle cap, the fluctuation range of the pulse type torsion formed by the influences of the magnetic pole distance, the magnetic pole magnetic force and the like during the slipping of the cap screwing is large, so that the screwing force of sample bottles after the cap sealing is finished is inconsistent, and the cap opening comfort is poor or the cap screwing is unqualified.

2. The part of the existing rotary punch adopts a mechanical friction conduction mode to conduct torque conduction, an upper mechanical friction plate and a lower mechanical friction plate are combined together, the lower friction plate is connected with the rotary punch, the upper friction plate is connected with a driving device, after a bottle cap is screwed on a bottle mouth, the rotary punch is blocked to stop rotating, a rotary driving piece is driven to rotate, and at the moment, the upper friction plate and the lower friction plate generate sliding wear. When the friction plate generates sliding wear, the torque fluctuation range is large under the influence of factors such as pressure and friction coefficient, so that the tightening force of the sample bottle after the cover is sealed is inconsistent, and the cover opening comfort is poor or the cover is unqualified.

3. The function of torque fixing of part of the existing cap screwing devices has no directivity, and the condition that the cap can not be opened is easily caused by reversely opening the cap after the cap is screwed forward, so that the cap screwing device is not suitable for occasions needing to close the cap and open the cap at the same time.

4. Some existing cap screwing devices are not strong in adaptability and cannot flexibly adjust the torque force, for example, different sample bottles may have different bottle cap screwing degrees, so that optimal cap screwing operation cannot be flexibly achieved for different sample bottles.
