Description

TECHNICAL FIELD

[0001] The application relates to the field of paper cup processing, in particular to a paper cup processing ultraviolet disinfection system. BACKGROUND

[0002] In the paper cup processing industry, the ultraviolet disinfection system as a key equipment to ensure the hygiene and safety of paper cups plays an indispensable role. During the production process of paper cups, strict disinfection treatment is needed to kill possible bacteria, viruses and other microorganisms, so as to ensure that the products meet the hygiene standards and meet the use requirements of consumers.

[0003] However, the existing ultraviolet disinfection system for paper cup processing has some problems to be solved in actual application. On the one hand, during the continuous disinfection operation, the ultraviolet lamp will generate a large amount of heat due to long-time continuous work. Since there is no effective heat dissipation mechanism, the temperature of the ultraviolet lamp will continue to rise. The high temperature not only accelerates the aging of the ultraviolet lamp, shortens its service life and increases the equipment maintenance cost, but also may cause the light-emitting efficiency of the ultraviolet lamp to decrease, affecting the disinfection effect and unable to guarantee the continuity and stability of the disinfection process.

[0004] On the other hand, after long-time use, the light-transmitting part of the ultraviolet lamp is easy to attach dust, impurities and other pollutants.

[0021] 2. When the drive motor starts, the drive shaft rotates through the transmission wheel and the transmission belt, and then the rotating disk rotates. The connecting rod drives the first piston plate to slide up and down, generating a one-way gas flow to dissipate the heat of the purple light board, which can prevent the purple light board from being damaged by overheating and increase its service life.

[0022] 3. During the gas flow process, the on-off control of the normally open solenoid valve is used to make the second piston plate move back and forth under the action of the spring, driving the rack to move, and then rotating the shaft.

The first one-way tube 12 and the second one-way tube 13 are both installed with a one-way valve. The other end of the first one-way tube 12 is connected with the interior of the rectangular groove 23. The one-way valve inside the first one-way tube 12 flows in a one-way direction from the outside into the first piston cylinder 11, and the one-way valve inside the second one-way tube 13 flows in a one-way direction from the first piston cylinder 11 to the outside. In use, when the rotating disk 10 rotates, a one-way gas flow between the rectangular groove 23, the first piston cylinder 11, the second piston cylinder 16 and the outside can be generated;

[0035] As an embodiment of the present invention, a transmission wheel 33 is installed on the output shaft of the driving motor 8 and the driving shaft 32, and the two transmission wheels 33 are connected by a transmission belt 9;

[0036] As an embodiment of the present invention, the inner top of the connecting box 5 is rotatably connected to a rotating shaft 19, the lower end of the rotating shaft 19 is fixedly connected to a rotating rod 21, the upper end of the rotating rod 21 is provided with a sponge layer, the sponge layer cooperates with the light-transmitting glass 26, the upper end of the rotating shaft 19 passes through the inner top of the connecting box 5, and is installed with a gear 20 through a one-way bearing, the upper end of the connecting box 5 is fixedly connected to the second piston cylinder 16, and the second piston cylinder 16 is provided with a second piston plate 29 that can slide back and forth, the front side of the second piston plate 29 is elastically connected to the front side wall of the second piston cylinder 16 by a spring 28, and the rear side of the second piston plate 29 is elastically connected to the front side wall of the second piston cylinder 16. A rack 30 is fixedly connected and meshes with the gear 20. When the rack 30 moves backward, the rotation of the gear 20 will not cause the rotating shaft 19 to rotate. When the rack 30 moves forward, the rotating shaft 19 can be rotated. Furthermore, when the rotating rod 21 does not rotate, it is in a position where it does not block the purple light panel 25. An exhaust hole 31 is provided at the top of the rear space of the second piston cylinder 16, and a release port 27 is provided in the front space of the second piston cylinder 16. The other end of the second one-way tube 13 is connected to the interior of the second piston cylinder 16. A normally open solenoid valve is installed in the release port 27, and the normally open solenoid valve opens and closes synchronously with the drive motor 8.

[0037] In the present invention, when in use, the drive motor 8 is started, and the output shaft of the drive motor 8 rotates. Since the output shaft of the drive motor 8 passes through the corresponding vertical mounting plate 3 and is fixedly connected to the front end rotating shaft of the right conveying roller 18, it will drive the right conveying roller 18 to rotate. The two conveying rollers 18 are jointly sleeved with a conveyor belt 4. Driven by the right conveying roller 18, the conveyor belt 4 starts to move, thereby realizing the transportation of the paper cups to be sterilized. The paper cups enter the connecting box 5 under the drive of the conveyor belt 4. The lower end of the disinfection box 22 at the top of the connecting box 5 is provided with a rectangular groove 23, and a purple light board 25 is installed inside the rectangular groove 23. A light-transmitting glass 26 is installed at the notch of the rectangular groove 23. The purple light board 25 emits ultraviolet light, which is used to sterilize the passing paper cups through the light-transmitting glass 26.

[0038] When the drive motor 8 is started, its output shaft is connected to the transmission wheel 33 mounted on the drive shaft 32 via the transmission belt 9, thereby driving the drive shaft 32 to rotate. The rotating disk 10 fixedly connected to the front end of the drive shaft 32 rotates accordingly, and the connecting rod 14, which is rotatably connected at the eccentric point on the front side of the rotating disk 10, drives the first piston plate 17 in the first piston cylinder 11 to slide up and down. In conjunction with the one-way valves inside the first one-way tube 12 and the second one-way tube 13, a one-way gas flow is generated between the rectangular groove 23, the first piston cylinder 11, the second piston cylinder 16, and the outside world. This allows the gas to flow, dissipating heat from the purple light panel 25 and extending its service life.

[0039] During continuous gas flow, since the normally open solenoid valve inside the release port 27 is energized and closed, the gas supply pushes the second piston plate 29 backward and stretches the spring 28. Since the gear 20 is mounted on the upper end of the rotating shaft 19 via a one-way bearing, when the rack 30 moves backward, the rotation of the gear 20 will not cause the rotating shaft 19 to rotate. When the drive motor 8 stops, the normally open solenoid valve opens, and the air in the rear space of the second piston cylinder 16 is discharged through the exhaust hole 31, and the air in the front space is discharged through the release port 27. The second piston plate 29 is reset and moved back under the action of the spring 28, driving the rack 30 forward. The rack 30 meshes with the gear 20, and the rotating shaft 19 can now rotate. The rotating rod 21 fixed to the lower end of the rotating shaft 19 rotates accordingly. The sponge layer on the upper end of the rotating rod 21 cooperates with the light-transmitting glass 26 to wipe and clean the light-transmitting glass 26, ensuring the light transmittance of the light-transmitting glass 26 and thus ensuring the subsequent disinfection effect. When the rotating rod 21 does not rotate, it is in a position where it does not block the purple light panel 25 and does not affect the normal progress of the disinfection work.

[0040] The present invention also discloses a method for using an ultraviolet disinfection system for paper cup processing, which uses the above disinfection system and includes the following steps:

[0041] First step: start the drive motor 8, the output shaft of the drive motor 8 rotates, because its output shaft penetrates the corresponding vertical mounting plate 3 and is fixedly connected with the front end rotating shaft of the right conveying roller 18, thereby driving the right conveying roller 18 to rotate, under the action of the two conveying rollers 18 and the jointly sleeved conveying belt 4, the conveying belt 4 starts to move, and the paper cup to be sterilized is conveyed into the connecting box 5;

[0042] Second step: the ultraviolet light plate 25 at the lower end of the top sterilization box 22 in the connecting box 5 emits ultraviolet light, which transmits through the light-transmitting glass 26 at the slot opening of the rectangular slot 23, and sterilizes the passing paper cup with ultraviolet light;

[0043] Third step: when the drive motor 8 is started, the one-way gas flow between the rectangular slot 23, the first piston cylinder 11, the second piston cylinder 16 and the outside can cool the ultraviolet light plate 25, thereby prolonging its service life;

[0044] Fourth step: when the drive motor 8 stops, the normally open electromagnetic valve opens, the air in the rear space of the second piston cylinder 16 is discharged through the exhaust hole 31, the air in the front space is discharged through the release port 27, the second piston plate 29 is reset and moves back under the action of the spring 28, the rack 30 moves forward, the rack 30 is engaged with the gear 20, the rotating shaft 19 rotates, the rotating rod 21 rotates, and the sponge layer at the upper end of the rotating rod 21 cooperates with the light-transmitting glass 26 to clean the light-transmitting glass 26, thereby ensuring the light-transmitting property of the light-transmitting glass 26.
