Background technology
In production, life process, often can run into the situation utilizing flush coater spraying protective layer or decorative layer on workpiece.Existing flush coater comprises workpiece placement station and spray body, wherein spray body " automatic enamel spraying device for casting iron pan production line " disclosed in Chinese patent CN201670876U, this spray body comprises the shower nozzle that can move left and right and the drive motors driving shower nozzle to move back and forth in the lateral direction.During use, workpiece is placed on the below of shower nozzle, the spraying completely realized workpiece is moved left and right by shower nozzle, existing this spray body Problems existing is: the stroke that moves left and right of shower nozzle is fixing, the uncomfortable timing of stroke is moved left and right when the length of workpiece and shower nozzle, such as the length of workpiece be less than spraying move left and right stroke, so when shower nozzle strides across workpiece, the spray paint sprayed by shower nozzle just can not be sprayed on workpiece, cause the waste of spray paint, workpiece and shower nozzle shift motion difference far away, this waste is more serious.
Summary of the invention
The purpose of this utility model is to provide a kind of shift motion can carry out according to Workpiece length the spray body that adjusts; The purpose of this utility model is also to provide a kind of flush coater using this spray body.
In order to solve the problem, in the utility model, the technical scheme of spray body is:
A kind of spray body, comprise the shower nozzle that can move left and right and the drive motors driving nozzle right movement, also comprise controller and the left and right position switch for detecting described nozzle position being arranged at nozzle right both sides, left and right position switch room is provided with the pitch adjusting structure of its distance between the two of adjustment, and left and right position switch is electrically connected with described controller.
Described left and right position switch is travel switch or proximity switch.
Described drive motors is servomotor.
Described pitch adjusting structure comprises the spacing adjustment screw mandrel that axis extends in left-right direction, spacing regulates on screw mandrel and is installed with and left screw and spacing can be regulated to regulate right screw relative to the spacing with opposing movement, described left position switch is arranged at described spacing and regulates on left screw, and described right position switch is arranged at described spacing and regulates on right screw.
In the utility model, the technical scheme of flush coater is:
A kind of flush coater, comprise spray body, spray body comprises the shower nozzle that can move left and right and the drive motors driving nozzle right movement, spray body also comprises controller and is arranged at the left and right position switch for detecting described nozzle position of nozzle right both sides, left and right position switch room is provided with the pitch adjusting structure of its distance between the two of adjustment, and left and right position switch is electrically connected with described controller.
Described left and right position switch is travel switch or proximity switch.
Described drive motors is servomotor.
Described flush coater also comprises the workpiece placement station of placing for workpiece, described pitch adjusting structure comprises the spacing adjustment screw mandrel that axis extends in left-right direction, spacing regulates on screw mandrel and is installed with and left screw and spacing can be regulated to regulate right screw relative to the spacing with opposing movement, spacing regulates left screw, spacing regulates right screw to be symmetrically arranged in the left and right sides of workpiece placement station left and right directions center line, described left position switch is arranged at described spacing and regulates on left screw, and described right position switch is arranged at described spacing and regulates on right screw.
The beneficial effects of the utility model are: pitch adjusting structure can realize the spacing adjustment of left and right position switch, during use, the spacing of left and right position switch is adjusted according to the length of workpiece, make spacing and the Workpiece length adaptation of left and right position switch room, the shift motion of shower nozzle is determined by the spacing of left and right position switch room, thus realize the adjustment of shower nozzle shift motion, the shift motion of shower nozzle and the length adaptation of workpiece can be accomplished, thus effectively avoid paint waste problem.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of flush coater in the utility model.
Detailed description of the invention
The embodiment of flush coater is as shown in Figure 1: the workpiece placement station comprising spray body and place for workpiece, comprise the shower nozzle that can move left and right and the drive motors being driven nozzle right movement by screw-nut mechanism, drive motors is servomotor, screw-nut mechanism comprises driving leading screw and spinning that axis extends in left-right direction in driving the driving screw on leading screw, and shower nozzle is arranged at and drives on screw.Spray body also comprise controller and be arranged at nozzle right both sides for detecting the left position switch of nozzle position and right position switch, controller belongs to prior art, its concrete structure no longer describes in detail, left and right position switch is proximity switch, left and right position switch is electrically connected with controller, and left and right position switch room is provided with the pitch adjusting structure of its distance between the two of adjustment.
Pitch adjusting structure comprises the spacing adjustment screw mandrel that axis extends in left-right direction, spacing regulates the two ends of screw mandrel to have the contrary positive and negative screw thread of rotation direction, positive and negative screw thread is installed with respectively and left screw and spacing can be regulated to regulate right screw relative to the spacing with opposing movement, left position switch is arranged at spacing and regulates on left screw, and right position switch is arranged at spacing and regulates on right screw.Workpiece placement station is arranged at the below of shower nozzle, and left and right position switch is symmetrically arranged in the left and right sides of workpiece placement station left and right directions center line.Figure middle term 8 represents the adjustment motor driving spacing to regulate screw mandrel rotation.
During use, workpiece is placed in workpiece placement station, screw mandrel is regulated to adjust a left side by spacing, the spacing of right position switch, make a left side, spacing between right position switch and Workpiece length adaptation, then drive motors drives nozzle right to move to spray workpiece, when shower nozzle moves to left position switch side, left position switch detects nozzle position, then corresponding detection signals is passed to controller, controller controls drive motors and quits work or commutation work, as a same reason, when shower nozzle moves to right position switch side, right position switch detects nozzle position, then corresponding detection signals is passed to controller, controller controls drive motors and quits work or commutation work.
In other embodiment of this flush coater: left and right position switch can also be travel switch; Servomotor also can be replaced by common electric machine; Left and right position switch also can not simultaneously move, such as one is fixed, and another is arranged at spacing and regulates on screw mandrel, and now left and right position switch need not be arranged symmetrically with the center line of workpiece placement station; Pitch adjusting structure may not be screw mandrel screw, such as pitch adjusting structure comprises gear and tooth bar, one of them position switch is arranged on tooth bar, moved left and right by the rotating band carry-over bar of gear, thus the spacing adjustment realized between two position switch, certain pitch adjusting structure can also be driving cylinder structure, now only needs one of them position switch to be arranged on the piston rod of driving cylinder.
The embodiment of spray body is as shown in Figure 1: the concrete structure of spray body is identical with the spray body described in above-mentioned each flush coater embodiment, is not described in detail in this.
