[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a high-gloss offset printing mechanism for paper cups, comprising a workbench 1, a control cabinet 3 is installed on one side of the workbench 1, a turntable 4 is rotatably connected to the front end of the workbench 1, a plurality of placement rods 5 are fixedly connected to the front end of the turntable 4, an offset printing device 6 is installed at the front end of the workbench 1, fixed blocks 20 are fixedly connected to the front ends of the placement rods 5, and a support plate 7 is rotatably connected to the inner side of the fixed block 20 through a rotating shaft. The user inserts the paper cup transmitted from the conveyor belt 2 into the front end of the placement rod 5, and controls the rotation of the turntable 4 and the rubber roller 18 inside the offset printing device 6 through the control cabinet 3. When the placement rod 5 rotates to the position of the rubber roller 18, the outer wall of the paper cup is fitted with the rubber roller 18, and the pattern is printed on the outer wall of the paper cup through the rotation of the rubber roller 18. When the placement rod 5 rotates to the bottom of the offset printing device 6, the user takes down the paper cup and puts it on the conveyor belt 2 for transmission. Through the rotation of the turntable 4, the equipment can be alternately printed to improve the printing efficiency.

[0023] Reference Figure 3 As shown, in the present embodiment: a storage groove 8 is provided at the front end of the placement rod 5, a push rod 9 is slidably connected inside the storage groove 8, a through groove 11 is provided on the top of the placement rod 5, and a connecting plate 12 is fixedly connected to the rear end of the top of the push rod 9. The user inserts the paper cup onto the support plate 7 at the front end of the placement rod 5, moves the connecting plate 12 forward, drives the push rod 9 to move forward, and pushes the support plate 7 to the four sides, so that the support plate 7 fits tightly with the inner wall of the paper cup. When contacting with the rubber roller brush 18, the pressure of the rubber roller brush 18 will not cause the paper cup to be displaced, causing the pattern to tilt. After printing, the connecting plate 12 is pushed backward to release the limit on the support plate 7, so that the paper cup can be easily removed.

[0024] Reference Figure 2 As shown, in this embodiment: the outer wall of the support plate 7 is fixedly connected with the anti-skid pad 10, the user inserts the paper cup onto the support plate 7 at the front end of the placement rod 5, moves the connecting plate 12 forward, drives the push rod 9 to move forward, and pushes the support plate 7 to the surroundings, so that the anti-skid pad 10 on the outer layer of the support plate 7 fits with the inner wall of the paper cup, thereby increasing the friction of the paper cup and preventing the support plate 7 from causing damage to the paper cup.

[0025] Reference Figure 1As shown, in this embodiment: the front end of the workbench 1 is fixedly connected with an arc plate 13, and both ends of the arc plate 13 are inclined surfaces. After the user inserts the paper cup onto the support plate 7 at the front end of the placement rod 5, the placement rod 5 is rotated to the inclined surface position of the arc plate 13 by rotating the turntable 4, and the connecting plate 12 is pushed forward by the inclined surface of the arc plate 13 to open the support plate 7, thereby increasing the friction with the inner wall of the paper cup, so that the paper cup will not be displaced due to the pressure of the rubber roller brush 18.

[0026] Reference Figure 3 As shown, in the present embodiment: the rear end of the push rod 9 is fixedly connected with a tension spring 14, and the rear end of the tension spring 14 is fixedly connected with the rear end of the storage groove 8. After the user inserts the paper cup onto the support plate 7 at the front end of the placement rod 5, the placement rod 5 is rotated to the inclined position of the arc plate 13 by rotating the turntable 4, and the connecting plate 12 is pushed forward by the inclined surface of the arc plate 13 to open the support plate 7. At the same time, the tension spring 14 accumulates force. After the placement rod 5 is printed, it is rotated to the notch of the arc plate 13, and the tension spring 14 pulls the push rod 9 to move backward to release the support for the support plate 7.

[0027] Reference Figure 4 and Figure 5 As shown, in this embodiment: two slide grooves 15 are provided at the front end of the workbench 1, a slider 16 is slidably connected inside the slide groove 15, a support frame 17 is fixedly connected to the front end of the slider 16, a rubber roller 18 is rotatably connected inside the support frame 17 through a rotating shaft, and when printing on paper cups of different specifications, the user can fine-tune the position of the rubber roller 18 by moving the support frame 17, so as to prevent the rubber roller 18 from having unclear printed patterns due to loose contact with the paper cup.

[0028] Reference Figure 5 As shown, in this embodiment: a thrust spring 19 is fixedly connected to one side of the slide groove 15, and the other end of the thrust spring 19 is fixedly connected to one side of the slider 16. When the user prints paper cups of different specifications, the thrust spring 19 on one side of the slider 16 causes the slider 16 to have a continuous thrust in the direction of the turntable 4, so that the rubber roller 18 can be in close contact with paper cups of different specifications, thereby preventing smaller paper cups from not being in contact with the rubber roller 18 and resulting in no pattern being printed.

[0029] Working principle: The user inserts the paper cup transmitted from the conveyor belt 2 into the front end of the placement rod 5, and controls the rotation of the turntable 4 and the rubber roller brush 18 inside the offset printing device 6 through the control cabinet 3. When the placement rod 5 rotates to the position of the rubber roller brush 18, the outer wall of the paper cup is fitted with the rubber roller brush 18, and the pattern is printed on the outer wall of the paper cup through the rotation of the rubber roller brush 18. When the placement rod 5 rotates to the bottom of the offset printing device 6, the user takes the paper cup off, puts it on the conveyor belt 2 for transmission, inserts the paper cup into the support plate 7 at the front end of the placement rod 5, and moves forward continuously. The connecting plate 12 drives the push rod 9 to move forward, and pushes the support plate 7 to open in all directions, so that the support plate 7 is closely fitted with the inner wall of the paper cup. When it contacts the rubber roller brush 18, the pressure of the rubber roller brush 18 will not cause the paper cup to move, resulting in the tilt of the pattern. After the printing is completed, the connecting plate 12 is pushed backward to release the support for the support plate 7, and the paper cup is inserted into the support plate 7 at the front end of the placement rod 5. The connecting plate 12 is moved forward, driving the push rod 9 to move forward, and the support plate 7 is pushed open in all directions, so that the anti-skid pad 10 on the outer layer of the support plate 7 is fitted with the inner wall of the paper cup. After the paper cup is inserted into the support plate 7 at the front end of the placement rod 5, the placement rod 5 is rotated to the inclined surface position of the arc plate 13 through the rotation of the turntable 4, and the connecting plate 12 is pushed forward by the inclined surface of the arc plate 13 to open the support plate 7, thereby increasing the friction with the inner wall of the paper cup. After the paper cup is inserted into the support plate 7 at the front end of the placement rod 5, the placement rod 5 is rotated to the inclined surface position of the arc plate 13 through the rotation of the turntable 4, and the connecting plate 12 is pushed forward by the inclined surface of the arc plate 13 to open the support plate 7, while the tension spring 14 accumulates force. After the placement rod 5 is printed, it rotates to the notch of the arc plate 13, and the tension spring 14 pulls the top rod 9 to move backward to release the support for the support plate 7. When printing on paper cups of different specifications, the position of the rubber roller brush 18 is slightly adjusted by moving the support frame 17 to prevent the rubber roller brush 18 from being in loose contact with the paper cup. When printing paper cups of different specifications, under the action of the thrust spring 19 on one side of the slider 16, the slider 16 has a continuous thrust in the direction of the turntable 4, so that the rubber roller brush 18 can be in close contact with paper cups of different specifications.
