Description

Technical Field

[0001] This utility model relates to the field of powder coating technology, and in particular to a safe and environmentally friendly powder recycling powder coating device. Background Technology

[0002] Powder coating involves charging plastic powder using a high-voltage electrostatic device. Under the influence of an electric field, the coating is sprayed onto the surface of the workpiece, where the powder is evenly adsorbed to form a powdery coating. After being baked at high temperature, the powdery coating flows and solidifies, and the plastic particles melt into a dense final protective coating with varying effects. Powder coating inevitably requires the use of powder coating equipment.

[0003] In the existing technology, most traditional powder coating equipment is used in open areas, where powder coating guns are connected to powder coating to workpieces. This powder coating method cannot recycle excess powder coating, resulting in powder coating waste, economic losses, and increased powder coating costs. At the same time, the scattered powder coating will cause environmental pollution, reducing the practicality and environmental friendliness of the powder coating equipment. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1 to 5 This utility model provides a safe and environmentally friendly plastic powder recycling and powder coating device, comprising a housing 1 and a fixing frame 2. The fixing frame 2 is fixedly installed on the inner wall of the housing 1. A placement seat 3 is fixedly installed on the upper surface of the fixing frame 2.

The side wall of the lifting frame 10 near the inner wall of the box 1 is fixedly installed with bristles 11. Inside the box 1, there is a recycling box 12. The inner wall of the recycling box 12 is slidably connected with an installation frame 14. The inner wall of the installation frame 14 is fixedly installed with a filter screen 15. The two side walls of the installation frame 14 are fixedly installed with positioning blocks 16. The inner walls of both sides of the recycling box 12 are provided with positioning grooves that are compatible with the positioning blocks 16.

[0024] To facilitate the fixing of the recycling bin 12, sliders 13 are fixedly installed on both side walls of the recycling bin 12.

[0026] The placement seat 3 is equipped with a positioning component, which includes an inner compartment 20. The inner compartment 20 is located inside the placement seat 3. A fixing rod 21 is fixedly installed on the inner wall of the inner compartment 20. Slide plates 22 are fitted on the outer surfaces of both ends of the fixing rod 21. A bidirectional lead screw 23 is rotatably connected to the inner wall of the inner compartment 20. The outer surface of the bidirectional lead screw 23 has a forward thread and a reverse thread. The side walls of the two slide plates 22 are respectively threaded to the two ends of the bidirectional lead screw 23 through the forward thread and the reverse thread. The bidirectional lead screw 23 passes through the inner wall of the inner compartment 20 and extends to the outside of the placement seat 3. A rotating block 24 is fixedly installed at the end of the bidirectional lead screw 23 away from the placement seat 3. A clamping plate 25 is fixedly installed on the upper surface of the slide plate 22. A guide groove that matches the clamping plate 25 is opened through the top wall of the inner compartment 20. A drainage groove 26 is opened through the bottom wall of the inner compartment 20.

[0027] By setting up an inner chamber 20, a fixing rod 21, a sliding plate 22, a two-way lead screw 23, a rotating block 24, a clamping plate 25, and a trough 26, the function of quickly fixing the workpiece is realized. By using the two-way lead screw 23 to drive the two sets of sliding plates 22 and clamping plates 25 to move closer to each other, the workpiece can be quickly clamped and fixed, saving time and effort and improving the ease of operation of the powder coating device. At the same time, by opening a trough 26 through the bottom wall of the inner chamber 20, the plastic powder entering the inner chamber 20 can fall downwards, preventing the plastic powder from accumulating in the inner chamber 20.

[0028] Working principle: When powder coating a workpiece, first place the workpiece on the upper surface of the placement seat 3, then rotate the rotating block 24. When the rotating block 24 rotates, it drives the bidirectional lead screw 23 to rotate inside the inner chamber 20. During the rotation of the bidirectional lead screw 23, the two sliding plates 22 are driven to move through the forward and reverse threads. Under the action of the fixed rod 21, the two sliding plates 22 move closer to each other inside the inner chamber 20 along the outer surface of the bidirectional lead screw 23 and the fixed rod 21. At the same time, the two clamping plates 25 move closer to each other along the guide groove. When both clamping plates 25 are in contact with the workpiece, the workpiece is fixed. After closing the door of the box 1, the powder coating device is started, so that the powder enters the interior of the connecting block 5 through the feeding pipe 4, and then is sprayed through the nozzle 6, thereby powder coating the workpiece.

[0029] During the powder coating process, some excess powder flows down through the fixed frame 2 into the recycling bin 12, some enters the inner chamber 20 and then flows through the trough 26 into the recycling bin 12, and some powder adheres to the inner wall of the bin 1. When the drive motor 7 is started, it drives the reciprocating screw 8 to rotate inside the bin 1. During the rotation of the reciprocating screw 8, it drives the lifting frame 10 to move. Under the action of the slide rod 9, the lifting frame 10 moves up and down inside the bin 1 along the outer surface of the reciprocating screw 8 and the slide rod 9. During this process, the lifting frame 10 drives the brush bristles 11 to brush the inner wall of the bin 1, brushing off the powder adhering to the inner wall of the bin 1. The brushed-off powder falls down and eventually enters the recycling bin 12, completing the powder positioning and recycling. During the powder recycling process, the powder passes through the filter screen 15, which intercepts impurities in the powder.

[0030] When too much plastic powder accumulates in the recycling bin 12, pull the pull block 18. The pull block 18 pulls the positioning rod 17 to extend away from the bin body 1. The tension spring 19 is stretched and deformed. After the positioning rod 17 slides out of the positioning hole, the restriction on the slider 13 is released, thereby releasing the fixation of the recycling bin 12. Then pull the recycling bin 12 to slide it out of the bin body 1. The slider 13 slides inside the slide groove. After the recycling bin 12 slides out of the bin body 1, pull the mounting frame 14 upward so that the mounting frame 14 slides upward along the inner wall of the recycling bin 12. The positioning block 16 slides inside the positioning groove. After the mounting frame 14 drives the filter screen 15 out of the recycling bin 12, the plastic powder in the recycling bin 12 can be processed. At the same time, the impurities on the filter screen 15 can be cleaned. After the plastic powder is processed, the above operation is reversed to reinstall the recycling bin 12 into the bin body 1.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
