Fluid spraying device with operation stability

Abstract

A fluid spraying device with operation stability is used for spraying fluid to a sprayed object (4) and comprises a shell (9), wherein the shell (9) is composed of an upper supporting part (92) and a lower driving containing part (91). The upper supporting part (92) is in sliding fit with a plurality of guide rods (93) to achieve supporting, wherein the guide rods (93) are fixedly connected with a fixing base frame (100). An internal thread gear disc (96) is clamped in an inner cavity (920) of the upper supporting part (92) through thrust bearings, and an internal thread is arranged on the inner circumference of the internal thread gear disc (96) to be matched with a walking threaded rod (95), wherein the walking threaded rod (95) is parallel to the guide rods (93) and penetrates through the inner cavity (920).

Description

technical field [0001] The invention relates to the field of fluid spraying, in particular to a fluid spraying equipment with stable operation. Background technique [0002] In the prior art, it is often necessary to spray fluid on the surface of some products, such as spraying on the surface of a steel plate for descaling, or spraying derusting oil on the surface of various metal products, such as the surface of a steel plate or a steel pipe. [0003] Since the target product has a certain width, and the spraying part of the spraying or spraying pipe needs to have a certain pressure and the spraying area is limited, therefore, it is necessary to swing the spraying part in the width direction to form a wide spray surface. However, it is difficult for some devices in the prior art to realize such swinging in the width direction while moving in the axial direction. And some similar devices are complex in structure and expensive. Contents of the invention [0004] The objec...
