[0054] Competitive landscape: There are multiple competitors in the market, the industry concentration is relatively high, and the top 5 manufacturers occupy a large market share.

[0055] Quick-drying spray paint has become one of the most important products in the coatings industry due to its efficient drying performance and wide range of applications. With continuous technological advancements and increasing market demand, the application scope and market size of quick-drying spray paint are expected to expand further.

[0056] Please see Figure 1-4 As shown, this embodiment provides a spray painting device with quick-drying function, including: a box body 1, a paint supply component is provided on the upper side of the box body 1, a spray painting chamber is provided horizontally in the box body 1, the spray painting chamber passes through the box body 1, a spray painting component and a drying component are provided in the spray painting chamber, and a conveying component is placed therein, the conveying component is located below the spray painting component and the drying component.

[0057] The painting assembly includes a motor 2 mounted on one side of the housing 1. A screw 3 is fixedly connected to the output shaft of motor 2, which transversely passes through the painting chamber and the housing 1. A slider 4 is slidably fitted onto the upper side of the painting chamber, and the slider 4 is threaded onto the circumference of the screw 3. A connecting block 5 is mounted on the lower side of the slider 4, and an adjustment groove is provided within the connecting block 5. A motor 6 is mounted on one side of the connecting block 5, and its output shaft passes through the adjustment groove. A rotating plate 8 is fixedly connected to the output shaft of motor 6. A fixing rod 9 is mounted on the upper part of one side of the rotating plate 8, which is located between motor 6 and the fixing rod 9. A sliding plate 10 is slidably fitted inside the groove. The sliding plate 10 has a horizontal groove that runs through it. A fixing rod 9 is located inside the groove. Two extension strips 11 are installed on the lower side of the sliding plate 10. A motor 6 is located between the two extension strips 11. The lower part of the extension strips 11 extends to the outside of the connecting block 5. A connecting plate 12 is installed on the lower side of the two extension strips 11. The connecting plate 12 is located between the connecting block 5 and the conveying component. A nozzle 14 corresponding to the paint supply component is provided on the connecting plate 12. The connecting plate 12 is installed around the nozzle 14. The nozzle 14 is located between the two extension strips 11.

[0058] One application of this embodiment is as follows: During use, the steel plate is placed on the conveying assembly for conveying. Depending on the thickness of the steel plate, motor 6 is started to drive the rotating plate 8 to rotate. The rotation of the rotating plate 8 drives the fixed rod 9 to rotate. The rotation of the fixed rod 9 presses against the lower side of the slide groove, causing the slide plate 10 to move downward. 、 The upper side of the extrusion chute moves the slide plate 10 upward. The displacement of the slide plate 10 causes the extension strip 11, connecting plate 12, and nozzle 14 to move, thereby adjusting the distance between the nozzle 14 and the steel plate on the conveying assembly. Then, the paint supply assembly supplies paint to the nozzle 14. According to the width of the steel plate, the motor 2 is started to drive the screw 3 to rotate. The rotation of the screw 3 causes the slider 4 to slide. The sliding of the slider 4 causes the connecting block 5 and the nozzle 14 to slide, thereby controlling the reciprocating movement of the nozzle 14. Then, the nozzle 14 sprays paint onto the steel plate. The painted steel plate is then conveyed to the bottom of the drying assembly for drying. It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power source.

[0059] The height of the nozzle 14 can be adjusted by the cooperation of the fixed rod 9 and the slide groove, so that the position height of the nozzle 14 can be adjusted according to the thickness of the steel plate. The screw 3 and the slider 4 cooperate to facilitate the operation of the motor 2. The reciprocating distance of the slider 4 can be adjusted according to the width of the steel plate to adjust the horizontal position of the nozzle 14, so that the nozzle 14 can spray paint evenly on the steel plate, improving the painting effect and uniformity of the nozzle 14 on the steel plate.

[0060] like Figure 2 As shown, the upper side of the spray booth in this embodiment is provided with a channel corresponding to the slider 4. The upper side of the slider 4 is slidably fitted in the channel. The sliding direction of the slider 4 is restricted by the channel, thereby improving the stability of the slider 4 when sliding.

[0061] like Figure 4 As shown, in this embodiment, extension plates 30 are installed on both sides of the adjustment groove, and the fixing rod 9 is located between the two extension plates 30. The inner sides of the two extension plates 30 are provided with grooves corresponding to the slide plate 10. The end of the slide plate 10 is slidably fitted in the groove. The lower side of the connecting block 5 is provided with a slot corresponding to the extension bar 11. The slot is connected to the adjustment groove, and the extension bar 11 passes through the slot. The sliding direction of the slide plate 10 is restricted by the groove, which improves the stability of the slide plate 10 when sliding. The stability of the extension bar 11 sliding up and down is improved by the slot.

[0062] like Figure 1 , 2 As shown, the paint supply assembly of this embodiment includes a paint storage tank 15 installed on the upper side of the housing 1. A liquid pump 16 is connected to one side of the paint storage tank 15. The inlet of the liquid pump 16 is connected to the inner cavity of the paint storage tank 15. The outlet of the liquid pump 16 is connected to a delivery pipe 13. One end of the delivery pipe 13 is connected to the upper end face of the nozzle 14. The delivery pipe 13 facilitates the operation of the liquid pump 16 to pump the paint in the paint storage tank 15 into the nozzle 14.

[0063] like Figure 1 As shown, the paint storage tank 15 in this embodiment is provided with a feed inlet 28 on the upper side. The feed inlet 28 is connected to the inner cavity of the paint storage tank 15. A dust cover 29 is snapped onto the upper part of the feed inlet. The feed inlet 28 facilitates the pouring of the prepared paint into the paint storage tank 15, and the dust cover 29 reduces the probability of dust entering the paint storage tank 15 through the feed inlet 28.

[0064] like Figure 1-3 As shown, the conveying assembly of this embodiment includes two fixed frames placed inside the housing 1. Two motors 20 are installed on one side of one of the fixed frames. The output shaft of the motors 20 is fixedly connected to a rotating rod 21. The rotating rod 21 passes through the two fixed frames laterally. Two gears 22 are installed around the rotating rod 21. The gears 22 are rotatably engaged in the corresponding fixed frames. Chains 23 are sleeved around the two gears 22 in the same fixed frame. Multiple conveying rods 24 are installed between the two chains 23.
