Automatic sample bottle cap screwing machine

Abstract

The invention discloses an automatic sample bottle cap screwing machine which comprises a rack, wherein a cap conveying device and a cap screwing device which are matched with each other are arrangedon the rack; the cap screwing device comprises a lifting assembly and a rotary puncher chip assembly arranged on the lifting assembly; the cap conveying device comprises a cap conveying assembly and acap jacking assembly; the cap conveying assembly is used for transferring multiple bottle caps to a position below the rotary puncher chip assembly one by one; the cap jacking assembly is arranged onthe cap conveying assembly in a rising and falling manner, is used for jacking up the bottle caps transferred in place, and then returns after conveying the bottle caps into the rotary puncher pin assembly; a bottle body fixing station is arranged below the rotary puncher pin assembly; and after receiving the bottle caps, the rotary puncher pin assembly rotates and falls towards the bottle bodiesunder the driving of the lifting assembly to drive the bottle caps to carry out cap screwing work. The automatic sample bottle cap screwing machine disclosed by the invention has the advantages of simple and compact structure, high automation and intelligence degree and high stability.

Description

technical field [0001] The invention mainly relates to the field of material sample collection and processing equipment, in particular to an automatic sample bottle capping machine. Background technique [0002] For the sampling, sample preparation, and testing of material (such as ore, coal) samples, each country has mandatory standards, and the sampling and processing of samples must be carried out in accordance with the standards. The principle of sample sampling, sample preparation, and testing work process is to gradually reduce the particle size and quality of the collected samples without destroying the representativeness of the sample, until it meets the particle size and quality of the sample in the laboratory test ( Weight) accuracy requirements, and then carry out relevant laboratory analysis on the samples that meet the requirements. [0003] For example, taking coal sampling as an example, it is actually a sampling and analysis process. The purpose of coal samp...

AI Technical Summary

Problems solved by technology

[0005] (1) The degree of automation and intelligence is low, and it cannot be reliably connected with external transmission equipment, and cannot realize a complete set of operations for continuous bottle blocking, reading and writing, cap feeding, cap screwing, and bottle push transportation, and cannot meet the entire process of sample collection and production. The need for automation and intelligence

[0006] (2) It is necessary to pre-screw the bottle cap on each sample bottle manually, and then tighten it by the capping machine, which cannot realize unmanned delivery of the cap; this not only increases labor intensity and labor cost, but also has low safety and is easy to There is a risk of artificial change

[0007] (3) Some sample bottle capping machines have a low degree of automation and cannot adjust the tightening torque flexibly and in real time. After repeated capping operations, the tightening torque of the bottle caps is inconsistent, which ultimately affects the sealing of the sample bottle

[0008] (4) Some sample bottle capping machines have poor safety. After they are screwed in place, they cannot be shut down in time, which causes the drive motor to be damaged or even burn out.

[0009] (5) The stability of some sample bottle capping machines is poor, and the bottle caps are not easy to be sent to the capping drive device. The bottle cap is easy to slip during the capping process, so that it is not really screwed in place, which affects the sealing of subsequent sample bottles

[0010] (6) The bottle body of some sample bottle capping machines is not easy to fix, so that the bottle body is easily affected and rotates synchronously during the capping process, so that the cap is not tight, and the bottle cap is easy to fall during the subsequent transportation process , causing the sample to spill

[0011] (7) Some sample bottle capping machines do not have the bottle cap detection function. When the equipment fails to cap the sample due to an accident, it is easy to cause the sample bottle filled with the sample without the cap to flow into the next link, causing the sample to spill; some Although the sample bottle capping machine has passed photoelectric detection, it cannot effectively distinguish whether there is a bottle cap or not when there is coal in the bottle mouth when the coal sample is too full.
