Examples

As shown in fig. 1-2, the present embodiment provides a technical solution: a rotary spray head for a metal product coating device comprises a base plate 1 which is connected with the coating device through screws, the upper end of the base plate 1 is horizontally connected with a mounting plate 10, the mounting plate 10 is vertically and rotatably connected with a rotating shaft 9 through a mounting bearing, the lower end of the rotating shaft 9 is horizontally connected with a fixed column 13, the fixed column 13 is sleeved with a sliding column 3 which can freely slide along the axial direction of the fixed column, the lower end of the sliding column 3 is provided with a spray head 17, a pipe joint 2 is connected on the spray head 17 in a penetrating way, the pipe joint 2 is connected with a coating liquid conveying device through a pipeline, so that the coating liquid conveying device can convey coating liquid to the spray head 17 through the pipe joint 2, a jig (not shown in the figure) for placing a workpiece is arranged under the fixed column 13, the upper end of the rotating shaft 9 is sleeved with a gear 8, an air cylinder 6 is arranged on the mounting plate 10 through a support, a rack 7 is horizontally connected on an air cylinder rod of the air cylinder 6, the rack 7 is engaged with the gear 8, so that when the cylinder rod of the cylinder 6 extends, the rack is driven to reciprocate, and then the rotating shaft 9 is driven to rotate in a reciprocating manner through the engagement transmission of the rack and the gear, so as to drive the spray head 17 to rotate around the axial direction of the rotating shaft 9, so that the spray head can rotate, meanwhile, a hollow flange seat 11 is arranged at the bottom of the mounting plate 10, the rotating shaft 9 can freely pass through the flange seat 11, in addition, the upper end of the sliding column 3 is vertically and fixedly connected with a fixed shaft 4, the fixed shaft 4 and the flange seat 11 are commonly connected with a pull rope 5 (which can be a nylon rope with higher tensile strength), in addition, one end of the fixed column 13 adjacent to the rotating shaft 9 is sleeved with a locking ring 14, the fixed column 13 is sleeved with a spring 16, two ends of the spring 16 in the elastic direction respectively elastically abut against the locking ring 14 and the fixed column 13, and when the state is shown in figure 1, the sliding column 3 is positioned at one end of the fixed column 13 far away from the rotating shaft 9 and is elastically abutted by the spring 16 to the sliding column 3, the pull rope 5 is in a stretched state at the moment, when the rotating shaft 9 rotates, the sliding column 3 axially rotates around the rotating shaft 9, because the flange seat is in a fixed installation state, the pull rope 5 is wound on the flange seat 11 along with the rotation of the fixed column 13, in the winding process, the pull rope 5 pulls the sliding column 3 to move towards the rotating shaft 9, and in the moving process, the sliding column 3 continuously compresses the spring 16, because the cylinder is controlled by an external electromagnetic valve, a cylinder rod is made to reciprocate and stretch, so that after the fixed column 13 rotates for a certain number of turns, the fixed column 13 reversely rotates, when the pull rope 5 reversely rotates, the pull rope 5 is uncoiled from the flange seat 11, at the pull force of the pull rope on the sliding column is gradually reduced, and because the elastic potential energy of the spring is released, the spring is converted from the compression state to an extension state, and then drive the sliding column to move to the position in figure 1 in the opposite direction, so repeatedly, make the shower nozzle can carry on the rotation around the axial of the spindle, can produce the horizontal displacement at the same time, thus make the spray coating range of the shower nozzle can basically cover the surface to be coated of the work piece, compared with the way of adopting a plurality of shower nozzles in the prior art, reduce the spray coating quality that is caused by the spray velocity inconsistency and is not the risk, in addition the structure in this embodiment is comparatively simple, make the manufacturing cost lower, in addition in order to the stability and will not produce the rotation around the axial of the fixed column when the sliding column 3 slides, can wear a short pin 19 on the sliding column 3, and set up the kidney slot 15 for short pin 19 to insert on the fixed column 13, through the short pin 19 slides in the kidney slot, make the sliding column will not produce the deflection phenomenon, in addition can mount the stop nut 18 on the fixed column, the limiting retainer ring 12 is adjusted at the lower end of the flange seat 11, and the pull rope 5 can be prevented from falling off from the lower end of the flange seat 11 by the limiting retainer ring 12.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
