Description

Needle fixing structure of cleaning machine

Technical Field

The utility model relates to a needle fixing structure of a cleaning machine.

Background

In the technical field of medicine and food packaging, the main function of the needle on the cleaning tube is to clean the inner wall of a container (bottle). The existing spray needle is directly connected with the thread of the cleaning pipe by adopting a sealing gasket, but the thread has the defects of easy abrasion, sliding teeth and the like, the reliability of the thread connection is relatively weak, and when the spray needle is vibrated, the thread is easy to loosen and water leakage occurs. And the needle and the cleaning tube are threaded, so that the cost is high, the installation is not easy, the needle needs to be screwed into the cleaning tube by means of a tool, the needle is easy to damage, and unnecessary cost loss is generated.

Accordingly, a needle fixing structure of a cleaning machine is provided for the above problems.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide the needle fixing structure of the cleaning machine, which has low processing cost and is more convenient to install and detach.

The technical scheme for achieving the purpose is as follows:

the needle fixing structure of the cleaning machine comprises an inner wall cleaning pipe, a plurality of needles, a needle fixing plate used for fixing the needles, a plurality of outer hexagon bolts, and a plurality of needles which are inserted into the inner wall cleaning pipe and are arranged in a row; the spray needle fixing plate penetrates through the spray needles to be arranged on the upper end face of the inner wall cleaning pipe, and each outer hexagon bolt sequentially penetrates through the flat gasket and the spring gasket to fix the spray needle fixing plate on the inner wall cleaning pipe.

Preferably, the upper end face of the inner wall cleaning pipe is provided with a plurality of steps, the lower end of the spray needle is provided with a boss, and the steps correspond to the bosses one by one.

Preferably, an O-ring groove is arranged at the lower end of the boss of the spray needle, and an O-ring matched with the O-ring groove is sleeved outside the O-ring groove.

The beneficial effects of the utility model are as follows: according to the utility model, the O-shaped ring groove is formed at the lower end of the spray needle and the O-shaped sealing ring is sleeved, so that the tightness between the lower end of the spray needle and the inner wall cleaning pipe is improved, the lower end of the spray needle is provided with the boss and the step on the inner wall cleaning pipe for positioning, the spray needle fixing plate is locked on the inner wall cleaning pipe through the flat washer, the spring washer and the outer hexagonal bolt, the sealing positioning installation of the spray needle is realized, and when the spray needle needs to be replaced, only the flat washer, the spring washer and the outer hexagonal bolt on the spray needle fixing plate are required to be loosened; the structure is simple and convenient to operate, three parts are replaced simultaneously, and meanwhile, the processing cost and the maintenance cost are greatly reduced.
