Description

Technical Field

[0001] This utility model relates to the field of surface spraying technology for environmentally friendly packaging materials, specifically to a surface spraying device for environmentally friendly packaging materials. Background Technology

[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivatives of the above basic spraying forms, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying.

[0003] For example, Chinese patent CN212943609U discloses an environmentally friendly packaging material surface spraying device, including a base plate. The upper surface of the base plate is connected to a top plate through two support plates. A drive motor is fixedly installed on the right side of the support plate. A lead screw is fixedly connected to the output end of the drive motor. A threaded slider is threadedly connected to the outer surface of the lead screw. A fixing plate is fixedly connected to the lower surface of the threaded slider. A cavity is opened inside the fixing plate. A rack is fixedly connected between the two support plates. A first rotating rod is rotatably connected to the top wall of the cavity through a bearing. A horizontal plate is fixedly connected to the opposite side of the two support plates.

[0004] The aforementioned surface spraying device for environmentally friendly packaging materials still has certain shortcomings. While the roller facilitates the compaction of the environmentally friendly packaging materials to prevent wrinkling, and the combination of the rack and toothed disc allows for the stirring of the dye inside the dye box when the threaded slider moves, the environmentally friendly packaging materials may require positional correction during transportation to avoid incomplete spraying. Therefore, this application proposes a surface spraying device for environmentally friendly packaging materials to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an environmentally friendly packaging material surface spraying device, which has advantages such as spraying and positioning of environmentally friendly packaging materials, and solves the problems in the background technology.

[0022] Understandably, the drying lamp 9 can dry the surface of the coated environmentally friendly packaging material.

[0023] Please see Figure 2 In this embodiment, the positioning mechanism 2 includes a first electric push rod 201 fixed to the front side of the top plate 6. A dye box 202 is fixed to the outer side of the output shaft of the first electric push rod 201. A connecting plate 203 is fixed to both the left and right ends of the dye box 202. A hinge plate 204 is hinged to the back side of the two connecting plates 203 through a hinge shaft. A fixing post 205 is fixed to the opposite side of the two vertical plates 7. A square cylinder 206 slides horizontally on the outer side of the two fixing posts 205. A fixing plate 207 is fixed to the opposite side of the two square cylinders 206. A movable plate 208 slides horizontally on the outer side of the two fixing plates 207. A spring 209 is fixed between the fixing plate 207 and the movable plate 208. A liquid injection pipe is connected to the front side of the dye box 202.

[0024] Two hinge plates 204 are respectively hinged to the front of two square cylinders 206 via hinge shafts. Multiple nozzles are connected to the back of the dye box 202. When the environmentally friendly packaging material moves to the bottom of the dye box 202, the first electric push rod 201 is activated, causing the dye box 202 to move to one side of the environmentally friendly packaging material, and driving the two hinge plates 204 to push the two fixed plates 207. When the two movable plates 208 contact the two sides of the environmentally friendly packaging material, the springs 209 begin to compress. At this time, the environmentally friendly packaging material can be corrected and positioned. The two vertical plates 7 are fixed with slides on opposite sides. The two connecting plates 203 slide inside the two slides respectively. After positioning, the surface of the environmentally friendly packaging material can be sprayed through multiple nozzles.

[0025] Please see Figure 3 In this embodiment, the collection mechanism 4 includes two second electric push rods 401 fixed to the front side of the base plate 1. The same first collection box 402 is fixed to the outside of the output shaft of the two second electric push rods 401. Two support plates 403 are fixed to the front side of the first collection box 402 and near its left and right ends. The same second collection box 404 is fixed to the front side of the two support plates 403. The first collection box 402 and the second collection box 404 are both located above the conveyor belt 5.

[0026] After the spraying is completed, the spraying condition can be detected by the image detection device 8. The unqualified environmentally friendly packaging materials can enter the second collection box 404, while the qualified environmentally friendly packaging materials can be moved to the top of the conveyor belt 5 by activating the second electric push rod 401, so as to facilitate the collection of qualified environmentally friendly packaging materials.

[0027] It is understood that all electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned in this article are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices. Therefore, this utility model will not explain the control method and circuit connection in detail. At the same time, all parts not described in detail in this utility model are common technologies known to those skilled in the art.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The working principle of the above embodiments is as follows:

[0030] When the environmentally friendly packaging material surface spraying device is needed, the environmentally friendly packaging material to be sprayed is placed on the surface of the conveyor belt 5. Then the conveyor belt 5 moves the environmentally friendly packaging material. When the environmentally friendly packaging material moves to the bottom of the dye box 202, the first electric push rod 201 is activated, causing the dye box 202 to move to one side of the environmentally friendly packaging material, and driving the two hinge plates 204 to push the two fixed plates 207. When the two movable plates 208 contact the two sides of the environmentally friendly packaging material, the spring 209 begins to compress. At this time, the environmentally friendly packaging material can be corrected and positioned. After positioning, the surface of the environmentally friendly packaging material can be sprayed through multiple nozzles. After the spraying is completed, the spraying status can be detected by the image detection device 8. The environmentally friendly packaging material that fails to pass the spraying can enter the second collection box 404. The environmentally friendly packaging material that passes the spraying can be moved to the top of the conveyor belt 5 by activating the second electric push rod 401, which facilitates the collection of qualified environmentally friendly packaging material.
