Pneumatic sampling device

Abstract

The invention relates to a pneumatic sampling device, which is characterized in that a rotating arm is connected onto a rack by a rotary shaft in a hinging manner; the rotating arm is driven by a swinging drive mechanism to be capable of swinging around the rotary shaft; a lifting air cylinder and a lifting guide rail are arranged on the rotating arm; a material reclaiming arm is slidably connected onto the lifting guide rail, and is connected with an end of a piston rod of the lifting air cylinder; the material reclaiming arm can slide up and down along the lifting guide rail under the driving of the lifting air cylinder; a material reclaiming air cylinder and a material reclaiming guide rail are installed on the material reclaiming arm; a material reclaiming pipe is slidably installed on the material reclaiming guide rail; the material reclaiming pipe is connected with the end of the piston rod of the material reclaiming air cylinder, and the material reclaiming pipe can slide up and down along the material reclaiming guide rail under the driving of the material reclaiming air cylinder; a joint lever is installed in the material reclaiming pipe in a penetrating manner; an upper end of the joint lever is installed on the material reclaiming arm; a lower end of the joint lever is provided with a seal valve; the seal valve is matched with a material reclaiming barrel; the seal valve is used for sealing the material reclaiming barrel. The pneumatic sampling device is simple in structure, stable in work, high in reliability, and convenient to maintain, capable of effectively solving the problem of difficulty in sampling in the automatic production.

Description

technical field

[0001] The invention relates to a pneumatic sampling device, which belongs to the technical field of mechanical equipment. Background technique

[0002] Today, with the continuous development and progress of science and technology, automation and intelligence have become the development trend in various fields; with the continuous improvement of living standards, the strictness of food hygiene and safety requirements is also increasing. Production automation that is not available in mechanical equipment, a large amount of manual labor is replaced by machines, and even the emergence of unmanned automatic production lines; the reduction in the number of staff means a sharp reduction in the chance of people contacting food, and the quality of food safety and hygiene. .

[0003] However, due to production needs, the frequency of sample extraction is gradually increasing. However, due to the single type of sampling equipment and the small range of options, the ex...
