Detailed description of the invention
The utility model provides a kind of cleaning apparatus for self of spray drying tower spray gun, below in conjunction with accompanying drawing, the utility model is described in further details.
A kind of cleaning apparatus for self of spray drying tower spray gun, at spray drying tower spray gun tail position, vibrator being set is fixedly connected with spray gun afterbody, or the striking mechanism that knocks described spray gun afterbody is set, vibration or knocking of striking mechanism by vibrator drive the vibration of spray gun afterbody and then make spray gun entirety produce vibration, by vibration, the deposit of the spray gun body of a gun and shower nozzle (being rifle head) are dropped.This device involving vibrations device or striking mechanism, mounting seat and controller
As shown in Figures 2 and 3, vibrator 200 is arranged in mounting seat 130, in preferred embodiment, vibrator 200 connects a fixed frame 140 and is erected in mounting seat 130 by fixed frame, and CD-ROM drive motor 210 is set above described fixed frame 140, spray gun afterbody 120 is set in fixed frame 140 and with fixed frame and is fixedly connected with.The size of fixed frame can be enclosed within spray gun afterbody just, and the support bar 141 that fixed frame arranges by both sides sets up in mounting seat.Carry out being connected of vibrator and described spray gun afterbody described in transition by fixed frame is set, the vibration that makes described vibrator, in playing and causing the vibration of the spray gun body of a gun, also avoids the vibration of vibrator to cause direct impact injury to spray gun gun barrel.
Further, the vibration head of vibrator is fixedly connected with fixed frame, therefore drives fixed frame vibration by vibration head, and then drives the vibration of the spray gun body of a gun.
It between fixed frame and mounting seat, is gapped connection, be not to be fixed together between support bar and mounting seat, the vibration that ensures so described fixed frame can not be delivered in mounting seat, affect the stability of mounting seat, in addition, also can not cause obstruction to the vibration of fixed frame, cause unnecessary power attenuation.Preferably, under the drive of vibrator, fixed frame is side-to-side vibrations in the horizontal direction, due to described support bar with mounting seat for being flexibly connected, support bar can not be subject to fixed frame horizontal vibration the impact of gun platform.
In another preferred embodiment, striking mechanism also can be set on spray gun afterbody, and as shown in Figure 4 and Figure 5, striking mechanism 300 comprises cylinder 310 and the drift 320 being connected with cylinder, drive drift to knock fixed frame 140 by cylinder, and then drive the vibration of the spray gun body of a gun.By setting in advance the power of cylinder and adjusting drift position, thereby adjust motion frequency and the impulsive force of drift, make knocking of striking mechanism can complete the vibration spray gun body of a gun, can not cause damage to spray gun gun barrel because impulsive force is excessive again.
Preferably, with the striking mechanism also supporting fixed frame that is provided with, striking mechanism be arranged on fixed frame directly over be installed in mounting seat, striking mechanism is connected with spray tower main body.Drift moves up and down and knocks fixed frame under the drive of cylinder, and fixed frame is same to be fitted tightly with spray gun afterbody, and the impulse force of drift impact fixed frame can be directly delivered to spray gun afterbody and cause the vibration of the body of a gun, thereby shakes off the deposit on rifle head and the body of a gun.The transition of fixed frame impulsive force to spray gun as striking mechanism, the impulsive force that drift is positioned to any converts to around the body vibration of spray gun gun barrel, has avoided due to the coup injury of Impulsive force of punch pin to spray gun gun barrel.
In preferred embodiment, the vibration frequency of vibrator be vibration in every 8 seconds once, time of vibration is that 3-5 minute, time of vibration are spaced apart 5-10 minute.
Further, the vibration of vibrator is moved by controller control motor driving vibrator.Its electrical work schematic diagram as shown in Figure 6, it mainly contains 2 time relay KT1 and KT2 composition, KT1 is for arranging the time interval of vibrations, KT2 is for arranging the time of vibrations, relay element KT1, KT2 and KA1 have switch and coil simultaneously, therefore in control principle drawing, separately illustrate, hereby explanation.Operation principle is in the time that main power switch SA is closed, 24V power supply obtains electric, power supply is the coil electricity to KT1 and KT2 by time delay normally-closed contact KT1, coil working, the time delay break contact closure of KT2 after coil working, KA1 coil electricity, KA1 normally opened contact closure, vibrator or striking mechanism motor energising work, in the time that the time arrives the time of KT2 setting, KT2 time delay break contact disconnects, KA1 coil blackout, the normally opened contact of KA1 disconnects, motor power-off stops vibrations, KT1 works on, in the time reaching the setup times at vibrations interval, KT1 moves, its time delay normally-closed contact is opened, the coil losing electricity of KT1 and KT2, enter next circulation.
Further, in spray gun rifle head, be provided with the baroceptor for detection of rifle head internal spraying gas pressure intensity, on the spray gun body of a gun, be provided for detecting the weight sensor of spray gun body of a gun weight, baroceptor is connected with the controller of vibrator or striking mechanism with weight sensor.The motor driving vibration head motion of controller control vibrator, or the cylinder of control striking mechanism drives drift motion.
The utility model can arrange described vibrator or the periodic operational vibration of striking mechanism, also can come Vibration on Start-up device or striking mechanism according to the feedback of baroceptor and weight sensor.In the time that baroceptor detects that spray gun rifle head internal gas pressure changes, illustrate that spray gun rifle head place very likely occurs that powder stops up the problem of rifle head, or in the time that described weight sensor detects described spray gun gun barrel changes in weight, illustrate and on spray gun gun barrel, be very likely stained with powder deposit, transmit the controller of interrupt signal to vibrator or striking mechanism according to above-mentioned situation baroceptor and weight sensor, controller is according to this feedback Vibration on Start-up device or striking mechanism work.
The utility model provides a kind of cleaning apparatus for self of spray drying tower spray gun, by vibrator or striking mechanism are set, the body of a gun of spray tower spray gun is vibrated, thereby the spraying powder particle depositing on spray gun spray nozzle and the body of a gun is shaken off.Realize the automatically cleaning to spray gun, ensured the continuity of spray tower spray effect and production.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
