Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, and in particular relates to a gradient spraying equipment for spraying colored crystal glass. Background Art

[0002] Colored crystal glass is an ideal new decorative material. A layer of colored coating with ink or a colored transparent coating with ink is printed on the surface of ordinary flat glass or tempered glass, and then a layer of resin with a cross-linked molecular structure is applied. Plastic colored grains (or glitter paper, gold powder, silver powder, laser powder) are pasted on the adhesive layer. After drying or air-drying, a layer of epoxy resin protective layer is applied to make colored crystal glass.

[0003] In order to meet more diverse needs, gradient products have appeared in the field of colored crystal glass. At present, the gradient products used in the field of colored crystal glass in the industry are all produced by screen printing (gradients with different effects are achieved by controlling the size of the screen dots) or glass inkjet printer printing. However, the gradient products produced by this method have a relatively stiff transition. Utility Model Content

[0004] The purpose of the utility model is to provide a gradient spraying device for colored crystal glass. By using a special fixture with an inclination angle of 15-45°, the amount of ink falling at each position is different, thereby achieving a gradient effect and making the gradient product transition smooth.

[0005] In order to achieve the above objectives, the technical solution adopted by the present invention is:

[0006] A gradient spraying device for colored crystal glass includes a spraying mechanism and a discharge mechanism for placing product plates. The discharge mechanism includes a base and a rotating seat hinged on the base, and the base is provided with an angle adjustment structure for adjusting the angle of the rotating seat. The angle adjustment range of the rotating seat is 15-45 degrees. A discharge plate is provided on the rotating seat. The spraying mechanism includes a spraying robot, which includes a mobile chassis and a robotic arm; a spraying device is installed at the end of the robotic arm.

[0007] Preferably, the angle adjustment structure includes an adjusting screw rod arranged on the base, the adjusting screw rod is matched with an adjusting handle, the adjusting screw rod is sleeved with an adjusting movable rod, the adjusting movable rod passes through the front and rear side plates of the base, and the front and rear side plates of the base are provided with adjusting slots that cooperate with the adjusting movable rod, both ends of the adjusting movable rod are sleeved with adjusting rotating arms, and the other end of the adjusting rotating arm is installed on the rotating seat through a pin shaft.

[0008] Preferably, adsorption holes are provided on the discharge plate, a sealing cover is provided in the rotating seat, the sealing cover, the discharge plate and the side wall of the rotating seat constitute an adsorption chamber, and an air pump connected to the adsorption chamber is provided on the sealing cover.

[0009] Preferably, the adsorption hole is equipped with a sealing ring, and the sealing ring protrudes from the upper surface of the discharge plate by 0.2-0.5 mm.

[0010] Preferably, the adsorption holes are distributed in a square array on the discharge plate, and the adsorption chamber is divided into adsorption channels by partitions. Each adsorption channel is connected to a part of the adsorption holes, and each adsorption channel is connected to an air extraction pump.

[0011] Preferably, the adsorption channel is linear or annular.

[0012] Preferably, a positioning mounting block is provided at the lower part of the lowest end of the discharge plate, the positioning mounting block is penetrated by a positioning screw, and the positioning screw adjusts its position on the positioning mounting block through a positioning nut, and the end of the positioning screw close to the lower end of the discharge plate is fixedly connected to the positioning block, and the positioning block extends beyond the discharge plate.

[0013] The technical effects of the utility model are:

[0014] 1. The discharge device drives the adjusting screw to rotate through the handle, and then the adjusting movable rod moves in the adjusting slot, so that the angle of the adjusting arm can be changed to achieve the angle adjustment of the rotating seat, and the inclination angle of the rotating seat can be adjusted in the range of 15-45°. The inclination of the rotating seat can make the amount of ink falling at each position of the product different, thereby achieving a gradient effect and making the transition of the gradient product smooth. By moving the chassis and the mechanical arm, the spraying distance of the spray gun can be shortened step by step to achieve a gradient effect.

[0015] 2. The design of the adsorption holes can adsorb the products on the discharge plate and then fix the products without interfering with the spraying of the products. The design of the sealing ring extending beyond the surface of the discharge plate can ensure that the product and the sealing ring form a closed cavity and will not cause air leakage due to slight unevenness on the surface of the discharge plate or the product. The design of the adsorption channel, which is linear or annular, can separate the adsorption of products to avoid air leakage in some adsorption holes affecting the overall adsorption effect.

[0016] 3. The design of the positioning block can limit the positioning of the lower end of the tilted product on the discharge plate, which can further balance the force of the gravity of the tilted product on the product, making the product on the discharge plate more stable.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1-2 As shown, the colored crystal glass gradient spraying equipment of this embodiment includes a spraying mechanism and a discharge mechanism 3 for placing product plates, the discharge mechanism 3 includes a base 11 and a rotating seat 12 hinged on the base 11, and the base 11 is provided with an angle adjustment structure for adjusting the angle of the rotating seat 12. The angle adjustment range of the rotating seat 12 is 15-45 degrees, and a discharge plate 13 is provided on the rotating seat 12.

[0029] The spraying mechanism includes a spraying robot, which includes a mobile chassis and a robotic arm; a spraying device 2 is installed at the end of the robotic arm, and the angle adjustment structure includes an adjusting screw 17 arranged on the base 11, and the adjusting screw 17 is matched with an adjusting handle 18. The adjusting screw 17 is sleeved with an adjusting movable rod 15, and the adjusting movable rod 15 passes through the front and rear side panels of the base 11, and the front and rear side panels of the base 11 are provided with an adjusting slot 14 that cooperates with the adjusting movable rod 15. Both ends of the adjusting movable rod 15 are sleeved with an adjusting rotating arm 16, and the other end of the adjusting rotating arm 16 is installed on the rotating seat 12 through a pin shaft.

[0030] The specific spraying steps of the spraying equipment of this embodiment are as follows:

[0031] 1) By mixing high temperature or low temperature ink and diluent in a certain ratio (the ratio of high temperature or low temperature ink and diluent is between 1:1-1:10);

[0032] 2) Place the prepared ink into the ink tank of the spray robot;

[0033] 3) After debugging the spray robot, control the ink output of the spray device 2 to be between 8-50g / 15s;

[0034] 4) Place the colored crystal glass product to be sprayed on the discharge plate 13 and then spray it. During the spraying process, the adjustment handle 18 drives the adjustment screw 17 to rotate, thereby moving the adjustment movable rod 15 in the adjustment slot 14. In this way, the rotating arm 16 can be adjusted to different angles, thereby adjusting the angle of the rotating seat 12 within 15-45 degrees, thereby achieving different ink scattering at different positions. At the same time, the mobile chassis and the mechanical arm of the spraying robot cooperate to adjust the stroke of the spraying device 2 to gradually shorten the spraying area (change in the number of layers in the gradient area) to achieve a gradient effect.

[0035] 5) Test the transmittance of different positions of the sprayed product and make sure the transmittance range is between 5% and 90% according to product requirements;

[0036] 6) Repeat steps 4) and 5) to spray multiple layers of gradient coating or directly spray or print several layers of topcoat to achieve a gradient effect.

[0037] Example 2

[0038] like Figure 3 and Figure 5As shown, the difference between this embodiment and Example 1 is that: adsorption holes 19 are provided on the discharge plate 13, and the adsorption holes 19 are distributed in a square array on the discharge plate 13. A sealing cover 21 is provided in the rotating seat 12. The sealing cover 21, the discharge plate 13 and the side wall of the rotating seat 12 constitute an adsorption chamber. The adsorption chamber is divided into linear or annular adsorption channels by partitions. Each adsorption channel is connected to a part of the adsorption holes 19, and each adsorption channel is connected to an air pump 22 arranged under the sealing cover 21. The adsorption holes 19 are equipped with sealing rings 20, and the sealing rings 20 protrude from the upper surface of the discharge plate 13 by 0.2-0.5 mm.

[0039] Compared with Example 1, this embodiment discloses how to achieve product fixation on the discharge plate 13. When the product plate is placed on the discharge plate 13, the product plate will contact all the sealing rings 20, and then form a cavity connected to the adsorption channel with all the sealing rings 20. The adsorption channel is then evacuated by the vacuum pump 22, so that negative pressure adsorption can be generated on the product plate through each adsorption hole 19, and it is divided into multiple adsorption channels to avoid poor sealing of the sealing ring 20 at a single adsorption hole 19. Even if this occurs, it will only affect the adsorption effect of the corresponding adsorption channel and will not interfere with the adsorption effects of other channels.

[0040] Example 3

[0041] like Figure 4 and Figure 6 As shown, compared with Example 2, the difference of this embodiment is that a positioning mounting block 24 is provided at the lower part of the lowest end of the discharge plate 13, and a positioning screw 25 passes through the positioning mounting block 24, and the positioning screw 25 adjusts its position on the positioning mounting block 24 through a positioning nut 26, and the end of the positioning screw 25 close to the lower end of the discharge plate 13 is fixedly connected with a positioning block 23, and the positioning block 23 extends beyond the discharge plate 13.

[0042] When the product is in an inclined state, after the gravity is decomposed, there will be a part of the downward force. In order to better ensure the stable installation of the product during the spraying process, this embodiment supports the lower end of the product through the positioning block 23, and the positioning block 23 can be adjusted by the positioning screw 25 and the positioning nut 26. Specifically, tightening the positioning nut 26 drives the positioning block 23 close to the discharge plate 13, and loosening the positioning nut 26 drives the positioning block 23 away from the discharge plate 13. In this way, corresponding adjustments can be made according to the size of the product plate.
