[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 2 A vertical air-drying device for silk-screened glass sheets comprises two elevators 5 located at the conveying end of a glass sheet conveyor 1. The adjacent sides of the two elevators 5 are vertically lifted. There are multiple receiving parts between the two elevators 5 that can receive the silk-screened glass sheets 2. The vertical air-drying device also includes a blowing component and a transition component 9. The blowing component can blow air horizontally into the space between the two elevators 5. The transition component 9 can transfer the silk-screened glass sheets 2 on the glass sheet conveyor 1 to the receiving parts.

[0021] The silk-screened glass sheet 2 after silk-screening is conveyed to the end by the glass sheet conveyor 1, and the silk-screened glass sheet 2 is transferred to the receiving part by the transfer component 9. The silk-screened glass sheet 2 on the receiving part is lifted up by one station by the elevator 5, and then the subsequent silk-screened glass sheets 2 are transferred to the elevator 5 in sequence, and are distributed on the elevator 5 in an upper and lower stacking manner. The silk-screened glass sheets 2 stacked up and down are blown dry by the blowing component, and then the dried silk-screened glass sheet 2 is removed from the top of the elevator 5 by machine or manually.

[0022] The device enables the silk-screened glass sheets 2 to be distributed on the elevator 5 in an upper and lower stacking manner, thereby effectively utilizing the upper space of the factory building and saving the factory building land area.

[0023] refer to Figure 1 Each elevator 5 includes two rollers 19, a first endless belt 4, and a rotary power source. The two rollers 19 are distributed vertically, and their axes are parallel to the conveying direction of the glass sheet conveyor 1. The first endless belt 4 connects the two rollers 19, and the rotary power source is in transmission connection with one of the rollers 19. The outer periphery of the first endless belt 4 has receiving strips 3 arranged parallel to the conveying direction of the glass sheet conveyor 1. The receiving strips 3 of the two elevators 5 located on the same horizontal plane form a receiving portion. The rollers 19 are driven by the rotary power source to rotate, and the belts on adjacent sides of the two elevators 5 move upward. This device evenly distributes multiple receiving strips 3 at intervals and horizontal distribution around the periphery of the first endless belt 4. The screen-printed glass sheets 2 are supported on the two receiving strips 3 on the same horizontal plane. Each time a screen-printed glass sheet 2 is conveyed, the elevator 5 lifts one workstation upward.

[0024] As a drying method, the blowing component includes a drying box 7, which is located on the side of the elevator 5 away from the glass sheet conveyor 1. The interior of the drying box 7 is hollow, and evenly distributed exhaust holes 6 are opened on the side close to the elevator 5. The drying box 7 is provided with an air inlet pipe 8, and the air inlet pipe 8 is connected to the hot air blower. The hot air flow is transported into the drying box 7 through the hot air blower. The hot air flow is blown through the exhaust holes 6 to the silk-screened glass sheets 2 stacked and spaced up and down on the elevator 5, and the silk-screened glass is dried by parallel wind.

[0025] refer to Figure 2 The transition component 9 includes a frame, a first pulley 13, a third pulley 14, and a second pulley 18, whose axes are arranged along the width direction of the glass sheet conveyor 1. The first pulley 13, the third pulley 14, and the second pulley 18 are distributed in a triangular orientation, and a second endless belt 15 is connected between the three; the third pulley 14 is rotatably connected to the frame, and the third pulley 14 is transmission-connected to the rotating motor, the first pulley 13 is rotatably connected to the first U-shaped bracket 12, and a first thrust elastic telescopic rod 11 is installed between the first U-shaped bracket 12 and the frame, and the telescopic direction of the first thrust elastic telescopic rod 11 is along The glass sheet conveyor 1 is set in the conveying direction; the second pulley 18 is rotatably connected to the second U-shaped bracket 17, and a second thrust elastic telescopic rod 16 is installed between the second U-shaped bracket 17 and the frame, and the second thrust elastic telescopic rod 16 is vertically arranged; the second endless belt 15 has an inclined belt portion 10 on the side close to the glass sheet conveyor 1. In the natural state, the lowest point of the inclined belt portion 10 is lower than the conveying surface of the glass sheet conveyor 1, and the highest point of the inclined belt portion 10 is higher than the conveying surface of the glass sheet conveyor 1, and preferably, the highest point of the inclined belt portion 10 is slightly higher than the upper plane of the receiving slat 3 of the receiving station.

[0026] When the device is working, the glass sheet conveyor 1 conveys the silk-screened glass sheet 2 to the position of the elevator 5. When the silk-screened glass sheet 2 gradually leaves the glass sheet conveyor 1, the front end of the silk-screened glass sheet 2 is supported on the inclined belt portion 10, and the operation of the third pulley 14 drives the second endless belt 15 to rotate, and the silk-screened glass sheet 2 is transferred from the glass sheet conveyor 1 to the receiving slat 3 through the second endless belt 15.

[0027] The second endless belt 15 is a rubber belt, which can prevent the silk-screened glass sheet 2 from colliding with the rubber belt and increase the friction force with the silk-screened glass sheet 2 .

[0028] Preferably, the elasticity of the first thrust elastic telescopic rod 11 is less than that of the second thrust elastic telescopic rod 16, and the elasticity of the second thrust elastic telescopic rod 16 is less than the weight of the silk-screened glass sheet 2. In a natural state, the highest point of the second endless belt 15 is higher than the conveying surface of the glass sheet conveyor 1, which can ensure that the silk-screened glass sheet 2 rests on the inclined belt portion 10. When most of the silk-screened glass sheet 2 is supported on the second endless belt 15, the second thrust elastic telescopic rod 16 is compressed downward, and the first thrust elastic telescopic rod 11 is extended to tighten the second endless belt 15. This structure can ensure that the second endless belt 15 is in close contact with the silk-screened glass sheet 2 to prevent the two from slipping. On the other hand, it can also enable the silk-screened glass sheet 2 to better transition from the second endless belt 15 to the receiving slats 3.

[0029] The above is only a preferred specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and utility model concept of the present invention by any technical personnel familiar with the technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
