[0055] As shown in Figure 3 and Figure 7 , the transmission mechanism 4 of the embodiment comprises a transmission belt 41, a rotating unit 42 and a rotating rod 43.

[0056] The two ends of the transmission belt 41 are rotationally connected with a rotating wheel 44, the rotating wheel 44 is rotationally connected with a power mechanism in a device cabin 45, and the shell on the side of the device cabin 45 facing the transmission belt 41 is a spray baffle.

The output of the rotating motor 421 is connected to the gearbox 422, which is in turn fixed to the rotating rod 43. A circular support 431 is fixedly mounted on the outside of the rotating rod 43. After the mouth of a glass bottle is inserted into the rotating rod 43, it is supported by the support 431. The upper portion of the support 431 is provided with a silicone layer. The mouth of the glass bottle rests vertically on the silicone layer above the support 431.

The blanking belt 51 close to the transmission mechanism 4 is located at the lower side of the transmission mechanism 4 and is inclined. The blanking belt 51 away from the transmission mechanism 4 is horizontally arranged.

[0059] In this embodiment, based on the structural features of the above-mentioned automatic spraying device for colored glaze on the surface of glass bottles, a method for automatically spraying colored glaze on the surface of glass bottles is proposed. The spraying method includes the following steps:

[0060] Step 1: Write a processing program in the programmable PLC, run and debug the movement stroke of each mechanism of the automatic spraying device, place the glass bottle horizontally on the conveying mechanism 1, and make the bottle mouth of the glass bottle face the moving direction, and the glass bottle is conveyed along the conveying mechanism 1 to the spraying mechanism 3.

[0061] In step 2, after the glass bottle reaches the rear end of the conveying mechanism 1, it is corrected by the guide plate 14 and slides downward obliquely with the bottle mouth facing downward. At this time, under the control of the programmable PLC, the rubber bottle holder 28 on the flipping mechanism 2 moves just below the slide plate 15, ensuring that the glass bottle slides into the rubber bottle holder 28 of the flipping mechanism 2. The rubber bottle holder 28 moves along an arc path, driving the bottle mouth in the rubber bottle holder 28 to move vertically downward. The transmission mechanism 4 drives the rotating rod 43 to rotate upward from bottom to top. Under the control of the programmable PLC, the end of the rotating rod 43 extends into the bottle mouth in the rubber bottle holder 28 along the operating path of the rubber bottle holder 28 and the rotating rod 43, and the glass bottle is picked out through the opening of the rubber bottle holder 28. The glass bottle changes from an oblique direction to a vertical direction with the bottle mouth facing downward until the bottle mouth of the glass bottle is supported by the support 431 on the rotating rod 43.

[0062] Step three, the rotating motor 421 of the rotating unit 42 is operated to rotate the rotating rod 43, and the glass bottle is rotated on the rotating rod 43 and the rotating unit 42 by the friction between the bottle opening of the glass bottle and the supporting table 431, and is horizontally moved along the transmission belt 41. According to the spraying requirement of the glass bottle, the nozzle 35 arranged on the adjusting frame 34 is adjusted to spray the colored glaze to the surface of the glass bottle at different heights and angles.

[0063] Step four, the glass bottle after the spraying is moved to the tail end along the transmission belt 41, is separated from the rotating rod 43, and is obliquely and downwardly slid to the discharging belt 51 of the discharging machine 5 to be transported to the next processing workshop.

[0064] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, equivalent replacement or change, should be covered in the protection scope of the present application.

The automatic spraying device for colored glaze on the surface of glass bottles according to claim 1, characterized in that: The transmission mechanism (4) includes a transmission belt (41), a rotating unit (42) and a rotating rod (43), the two ends of the transmission belt (41) are rotationally connected to the rotating wheel (44), the rotating wheel (44) is rotationally connected to the power mechanism in the equipment cabin (45), the shell of the equipment cabin (45) facing the transmission belt (41) is a spray baffle, and the programmable PLC is also provided in the equipment cabin (45) for establishing a control connection with the power mechanism in the equipment cabin (45); the rotating units (42) are fixedly installed on the outer surface of the transmission belt (41) at equal intervals.

7. The automatic spraying device for colored glaze on the surface of glass bottles according to claim 6, characterized in that: The rotating unit (42) comprises a rotating motor (421) and a gearbox (422). The output end of the rotating motor (421) is connected to the gearbox (422), and the output end of the gearbox (422) is fixed to the rotating rod (43). A circular support platform (431) is fixedly provided on the outside of the rotating rod (43). After the mouth of the glass bottle is inserted into the rotating rod (43), it is supported by the support platform (431). The upper part of the support platform (431) is provided with a silicone layer.

8. The automatic spraying device for colored glaze on the surface of glass bottles according to claim 1, characterized in that: The blanking machine (5) is composed of a blanking belt (51) and side plates (52), wherein the side plates (52) are arranged on both sides of the blanking belt (51), the blanking belt (51) close to the transmission mechanism (4) is located below the side of the transmission mechanism (4) and is arranged in an inclined manner, and the blanking belt (51) away from the transmission mechanism (4) is arranged horizontally.

9. A method for spraying colored glaze on the surface of a glass bottle using the automatic spraying device according to any one of claims 1 to 8, characterized in that: The spraying method comprises the following steps: Step 1: Write a processing program in a programmable PLC, run and debug the motion stroke of each mechanism of the automatic spraying device, place the glass bottle on the conveying mechanism (1), and convey it along the conveying mechanism (1) to the spraying mechanism (3); Step 2: After the glass bottle is transported to the tail end of the conveying mechanism (1), it slides obliquely downward with the bottle mouth facing downward into the rubber bottle holder (28) of the flipping mechanism (2). The rubber bottle holder (28) runs along an arc trajectory, so that the bottle mouth of the glass bottle in the rubber bottle holder (28) moves in a vertical downward direction. The transmission mechanism (4) drives the rotating rod (43) to rotate from bottom to top. Through the control of the programmable PLC, on the running trajectory of the rubber bottle holder (28) and the rotating rod (43), the end of the rotating rod (43) extends into the bottle mouth of the glass bottle in the rubber bottle holder (28), and the glass bottle is picked out through the opening of the rubber bottle holder (28); Step 3: The glass bottle rotates on the rotating rod (43) and the rotating unit (42) and moves horizontally along the transmission belt (41), and the nozzle (35) provided on the adjustment frame (34) sprays the colored glaze onto the surface of the glass bottle at different heights and angles; In step 4, the sprayed glass bottle moves along the transmission belt (41) to the tail end and then separates from the rotating rod (43), and slides obliquely downward onto the unloading belt (51) of the unloading machine (5) and is transported to the next processing workshop.
