Refluxing cleaning structure and cup for filling machine

Abstract

The invention discloses a refluxing cleaning structure for a filling machine. The refluxing cleaning structure comprises a filling valve and a cleaning cup suspended at the lower end of the filling valve, wherein a valve head is arranged in the filling valve; an exhaust pipe is arranged in the valve head; a liquid injection flow channel is formed between the valve head and the exhaust pipe; a liquid injection opening is formed at the lower end of the liquid injection flow channel; an exhaust port is formed at the lower end of the exhaust pipe; the cleaning cup comprises a cup body, a connection pipe and a top pipe; a flow guide cavity is formed in the cup body; the inner diameter of the flow guide cavity is greater than the outer diameter of the valve head; a refluxing gap into which cleaning liquid flows is formed between the cup body and the outer wall of the valve head; the top pipe is arranged at the bottom of the flow guide cavity; the top pipe is pressed against the exhaust portof the exhaust pipe and communicated with the exhaust pipe so as to be stopped between the liquid injection opening and the exhaust port of the valve head; the cleaning liquid flows out of the liquidinjection opening through the valve head and turns to the refluxing gap after being resisted by the top pipe; the connection pipe is arranged beside the outer side of the cup body; the upper end of the connection pipe is communicated with the refluxing gap and a butting slot, and the lower end of the connection pipe is communicated with the lower end of the top pipe; and the cleaning cup structure can clean the outer wall of the valve head.

Description

technical field [0001] The invention relates to the field technology of a filling machine cleaning device, in particular to a backflow cleaning structure of a filling machine and a cleaning cup thereof. Background technique [0002] Filling is a technology used to fill various materials such as gas-containing liquids and non-gas liquids into various packaging containers such as bottles, cans, boxes, barrels or bags. The use of mechanized filling can not only improve productivity, Reduce product loss, ensure packaging quality, and reduce mutual pollution between the production environment and the loaded materials. Therefore, the current filling technology has been widely used in the automatic filling production of pharmaceutical, daily chemical, food and special industry factories. [0003] In order to ensure the cleanliness of the filling machine and the hygiene and safety of the filling materials, it is necessary to perform CIP cleaning on the pipes and tanks of the fillin...

AI Technical Summary

Problems solved by technology

[0005] Although this traditional cleaning cup structure can realize its basic function of blocking the valve head of the filling valve during the cleaning operation, it has many shortcomings in its own structure and performance in actual use, and cannot achieve the best performance. Effect

Its shortcoming is that this device can only clean the inner wall of the valve head, but the outer wall of the valve head and the docking groove of the filling valve are not within the return range of the CIP cleaning liquid, the cleaning range is not comprehensive, and the cleaning effect is not good. When cleaning the outer wall of the valve head and the docking groove, the cleaning cup must be disassembled, and then the outer wall of the valve head or the docking groove must be cleaned manually, which will increase the labor force of the workers and prolong the cleaning time, and cannot achieve comprehensive cleaning. automation, convenience

In addition, the device has many assembly parts, which is troublesome to assemble and disassemble, which is very time-consuming and labor-intensive, which brings inconvenience to users.
