Specific implementation

[0029] Referring Figures 1-8 , the utility model provides a kind of precision coater for environmental protection decorative roll coating aluminium plate production line: including rack 1, rack 1 top is equipped with paint roller 2, rack 1 top is also equipped with paint box 3, paint box 3 bottom is equipped with multiple spray heads 4, paint box 3 is located paint roller 2 top, paint box 3 bottom both ends are equipped with guide assembly, guide assembly includes guide plate 5, mounting plate 6 and positioning block 7, the quantity of mounting plate 6 and positioning block 7 is two, two mounting plates 6 bottom are respectively fixedly connected with the top both ends of guide plate 5, two mounting plates 6 one side are equipped with the groove 8 for positioning block 7 movement, and positioning block 7 is connected with the inboard of groove 8 by spring 9, paint box 3 bottom is equipped with multiple sliding grooves 10 for mounting plate 6 and positioning block 7 movement, and the inboard of sliding groove 10 is equipped with multiple clamping grooves 11 matched with positioning block 7, guide plate 5 top is equipped with guide groove 12, and guide groove 12 bottom end is inclinedly arranged;

[0030] The positioning block 7 is located at one end of the card slot 11 and is inclined to the center of both sides. The guide plate 5 is provided with a positioning member on both sides, which includes a support plate 13 and a movable plate 14. One end of the support plate 13 is fixedly connected with one side of the guide plate 5, and the bottom of the movable plate 14 is fixedly connected with the top of the support plate 13. The side of the movable plate 14 away from the guide plate 5 is provided with a support block 15. The bottom of the paint box 3 is provided with a plurality of limiting grooves 16 for the movement of the movable plate 14 and the support block 15.

[0031] The connecting rod 17 is provided at the four corners of the bottom of the paint box 3 and is fixedly connected with the top of the rack 1. The top of the rack 1 is also provided with a plurality of limiting rollers 18 for limiting the aluminum plate. The top of the paint box 3 is provided with a feeding port 19 for adding paint. The paint in the paint box 3 can be supplemented through the feeding port 19 provided at the top of the paint box 3. The paint box 3 is supported by the connecting rod 17 provided at the four corners of the bottom of the paint box 3. The aluminum plate to be processed is limited by the plurality of limiting rollers 18 provided at the top of the rack 1, preventing the aluminum plate from shifting during movement.

[0032] Working principle:

[0033] When the size of the aluminum plate to be processed is small, the guide plate 5 is pushed to move the mounting plate 6 and the positioning block 7 provided at the top of the guide plate 5 inside the sliding groove 10 opened at the bottom of the paint box 3. Because the positioning block 7 is located at one end of the card slot 11 and is inclined to the center of both sides, when the outer side of the positioning block 7 is pressed against the inner side of the card slot 11, the positioning block 7 will be subjected to a pressing force. The inclined surfaces provided on both sides of the positioning block 7 convert the pressing force into a pushing force in the direction of the recess 8, thereby moving the positioning block 7 inside the recess 8 and pressing the spring 9. When the positioning block 7 completely separates from the inside of the card slot 11, the guide plate 5 is continuously pushed. When the positioning block 7 moves to the position of another card slot 11 opened inside the sliding groove 10, it will move towards the inside of the card slot 11 under the elastic action of the spring 9, so that the outer side of the positioning block 7 is in close contact with the inner side of the card slot 11, thereby completing the fixation of the guide plate 5. The nozzle 4 provided at the outer end of the bottom of the paint box 3 is shielded by the guide plate 5, so that the paint sprayed by the nozzle 4 flows along the guide groove 12 opened at the top of the guide plate 5, thereby allowing the paint to drop on the surface of the paint roller 2 and be absorbed by it. By adjusting the two guide plates 5, the drop area of the paint can be adjusted according to the size of the aluminum plate, thereby preventing the paint from dropping on both ends of the paint roller 2 and reducing the waste of paint.

[0034] When the guide plate 5 moves, the movable plates 14 and the supporting blocks 15 arranged on both sides of the guide plate 5 move in the limiting grooves 16 opened in the bottom of the paint box 3; the movable plates 14 can ensure the stability of the guide plate 5 when the guide plate 5 moves, and prevent the guide plate 5 from deviating; the supporting blocks 15 can support the guide plate 5 and prevent the guide plate 5 from shaking due to gravity;

[0035] The paint in the paint box 3 can be supplemented through the feeding opening 19 arranged on the top of the paint box 3; the paint box 3 is supported through the connecting rods 17 arranged at the four corners of the bottom of the paint box 3;

[0036] The aluminum plate is placed on the top of the rack 1 and moves under the transportation of the rack 1; the aluminum plate is limited through the multiple limiting rollers 18 arranged on the top of the rack 1, so that the aluminum plate does not deviate during the movement; and the surface of the aluminum plate is coated through the paint roller 2 arranged on the top of the rack 1.

[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
