Description

Technical Field

[0001] This utility model relates to the field of spray painting technology, and in particular to a spray painting device for furniture panels. Background Technology

[0002] Furniture panels are commonly used raw materials in furniture production. They are typically made of wood, synthetic materials, or other man-made materials, and have different physical properties and appearances to meet various furniture design and functional requirements. To enhance the aesthetic appeal of furniture, provide a protective layer, and increase its durability, the panels are usually painted, achieving both decorative and functional effects.

[0003] Existing painting processes are performed manually. Manual painting of boards is not only slow, but also results in inconsistent spraying speed and application rates, leading to uneven coating and affecting the overall appearance of the boards. Therefore, this invention proposes a painting device for furniture boards to solve the aforementioned technical problems. Utility Model Content

[0004] In order to overcome the shortcomings of low efficiency, inconsistent painting effect and poor quality of board materials caused by manual painting process, this utility model provides a painting device with a spray nozzle that can rotate back and forth to spray paint evenly.

[0005] A painting device for furniture panels includes a housing and an observation window. The housing is an open frame structure with a transparent observation window on its side. It also includes a spray head, a first motor, a fixing block, a slide rod, a turntable, and a cam. The first motor is bolted to the top surface of the housing. The output shaft of the first motor is keyed to the turntable. The cam is fixed to the eccentric part of the turntable. A transverse groove is provided on the top surface of the housing. The fixing block is fixed to the end of the groove. The slide rod is slidably connected between the fixing blocks. The spray head is connected inside the slide rod and extends downward into the housing. The cam is limited and slides within the slide rod.

[0006] As an improvement to the above solution, it also includes a feed pipe, a diaphragm pump, and a material box. The material box is fixed to the top surface of the box body with bolts, the diaphragm pump is fixed to the top surface of the box body, the material box outlet is connected to the diaphragm pump inlet, and the diaphragm pump is connected to the nozzle through the feed pipe.

[0007] As an improvement to the above solution, it also includes a transmission bracket, a second motor, and a transmission belt. The transmission bracket is fixed to the bottom of the housing, the transmission belt is wound around the transmission bracket, and the second motor can drive the output belt to rotate.

[0008] As an improvement to the above solution, it also includes a scraper and a waste box. The scraper is fixed to the transmission support and can make frictional contact with the transmission belt. The waste box is fixed to the lower part of the transmission support and is located below the scraper.

[0009] As an improvement to the above solution, it also includes a bellows and a fan. The bellows are symmetrically fixed to the side of the transmission support, and the fan is installed on the inner wall of the bellows.

[0010] As an improvement to the above solution, a guide plate is also included. The guide plate is a cube with an inclined surface. The guide plate is fixed to the end of the transmission support and can be connected to the end face of the transmission belt.

[0011] The beneficial effects achieved by this utility model through the above solution are as follows:

[0012] The first motor is turned on to drive the turntable to rotate. Because the turntable has a cam at its eccentric position and the cam slides within the slide rod, the cam can drive the slide rod to slide back and forth in the horizontal direction as the turntable rotates. This, in turn, drives the spray head to slide back and forth. Compared with the traditional method of manually spraying paint onto the board with a handheld spray gun, this device can achieve uniform painting of the board by the reciprocating movement of the spray head. This not only improves the painting efficiency of the board but also ensures uniform painting quality and guarantees the quality control of the board before it leaves the factory.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] A painting device for furniture panels, such as Figures 1-6 As shown, the device includes a housing 1 and an observation window 2. The housing 1 is an open frame structure with a transparent observation window 2 on its side. It also includes a nozzle 3, a first motor 4, a fixing block 5, a slide rod 6, a turntable 7, and a cam 8. The first motor 4 is fixed to the top surface of the housing 1 by bolts. The output shaft of the first motor 4 is connected to the turntable 7 by a key. The cam 8 is fixed to the eccentric part of the turntable 7. A transverse sliding groove is provided on the top surface of the housing 1. The fixing block 5 is fixed to the end of the sliding groove. The slide rod 6 is slidably connected between the fixing blocks 5. The nozzle 3 is connected inside the slide rod 6 and extends downward into the interior of the housing 1. The cam 8 is limited and slides within the slide rod 6.

[0022] like Figure 1 and Figure 3 As shown, it also includes a feed pipe 9, a diaphragm pump 10 and a material box 11. The material box 11 is fixed to the top surface of the box body 1 by bolts. The diaphragm pump 10 is fixed to the top surface of the box body 1. The discharge port of the material box 11 is connected to the inlet of the diaphragm pump 10. The diaphragm pump 10 is connected to the nozzle 3 through the feed pipe 9.

[0023] like Figure 1 , Figures 4-6 As shown, it also includes a transmission bracket 12, a second motor 13 and a transmission belt 14. The transmission bracket 12 is fixed to the bottom of the housing 1, the transmission belt 14 is wound around the transmission bracket 12, and the second motor 13 can drive the output belt to rotate.

[0024] like Figure 4 As shown, it also includes a scraper 15 and a waste box 16. The scraper 15 is fixed to the transmission support 12 and can make frictional contact with the transmission belt 14. The waste box 16 is fixed to the lower part of the transmission support 12 and is located below the scraper 15.

[0025] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a bellows 17 and a fan 18. The bellows 17 is symmetrically fixed to the side of the transmission bracket 12, and the fan 18 is disposed on the inner wall of the bellows 17.

[0026] like Figure 1 and Figure 6As shown, it also includes a guide plate 19, which is a cube with a bevel. The guide plate 19 is fixed to the end of the transmission bracket 12 and can be in contact with the end face of the transmission belt 14.

[0027] The second motor 13 is turned on to drive the transmission belt 14 to rotate. The board is then placed at the rear end of the transmission belt 14 and enters the box 1 along with the transmission belt 14. The first motor 4 is turned on to drive the turntable 7 to rotate. Because the turntable 7 is provided with a cam 8 at the eccentric position and the cam 8 is limited to slide within the slide rod 6, when the cam 8 rotates with the turntable 7, the cam 8 can drive the slide rod 6 to slide back and forth in the horizontal direction, thereby driving the spray head 3 to slide back and forth. During this period, the diaphragm pump 10 introduces the paint in the material box 11 into the spray head 3. The reciprocating spray head 3 will spray the board evenly. After the spraying is completed, the fan 18 will air dry and shape the board. Finally, the guide plate 19 will guide and collect the material, and the scraper 15 can scrape the paint attached to the transmission belt 14 into the waste box 16 for recycling.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
