[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides an automatic splicing device for white cardboard, including a base plate 1, a vertical plate 2 fixedly connected to the back of the base plate 1, a top plate 3 fixedly connected to the front of the vertical plate 2, a moving mechanism 4 provided on the front of the vertical plate 2 (two sets of moving mechanisms 4), a sensing mechanism 5 provided on the front of the vertical plate 2 (two sets of sensing mechanisms 5), a slider 6 slidably connected inside the vertical plate 2 (two sets of slider 6), a material rod 7 rotatably connected to the front of the slider 6, paper rolls 8 provided on the periphery of the material rod 7, a vacuum pump 9 provided on the back of the vertical plate 2, a connecting pipe 10 fixedly connected to the input end of the vacuum pump 9, a solenoid valve 11 provided at the upper end of the connecting pipe 10 (two sets of solenoid valves 11), a connecting box 12 fixedly connected to the front of the vertical plate 2 (two sets of connecting boxes 12), the connecting pipe 10 communicating with the connecting box 12, a high-pressure pipe 13 fixedly connected to the front of the connecting box 12 (two sets of high-pressure pipes 13), and a slot matching the slider 6 through the front of the vertical plate 2 for the slider 6 to slide.

The high-pressure pipe 13 is fixedly connected to the positioning plate 43 through the connector. The high-pressure pipe 13 is connected to the air hole 44. After the vacuum pump 9 is started, air will be drawn from the air hole 44. At this time, the paper roll 8 can be sucked onto the surface of the positioning plate 43.

[0039] Specifically, the bottom plate 43 has a base block fixedly connected to both the left and right sides of its bottom surface, and the first rotating roller 45 is rotatably connected to the base block.

[0040] Specifically, the sensing mechanism 5 includes a second fixed plate 51, a slide rod 52, a connecting plate 53, a connecting block 54, a second rotating roller 55, a spring 56, and a sensor 57. The second fixed plate 51 is fixedly connected to the front of the upright plate 2. The slide rod 52 is slidably connected to the second fixed plate 51, and the slide rod 52 is provided in two sets. The connecting plate 53 is fixedly connected to the upper end of the slide rod 52, and the connecting block 54 is fixedly connected to the bottom end of the slide rod 52. The second rotating roller 55 is rotatably connected between the two sets of connecting blocks 54. The spring 56 is sleeved on the periphery of the slide rod 52.

[0041] Specifically, a slot is provided at the upper end of the top plate 3, through which the paper roll 8 passes.

[0042] Specifically, a lead screw 14 is rotatably connected inside the upright plate 2, and two sets of lead screws 14 are provided. The lead screw 14 is threadedly connected to the slider 6, and a first bevel gear 15 is fixedly connected to the upper end of the lead screw 14.

[0043] Specifically, a dual-head motor 16 is installed at the upper end of the upright plate 2, and the two output ends of the dual-head motor 16 are fixedly connected to the transmission rod 17.

[0044] Specifically, a second bevel gear 18 is fixedly connected to the end of the transmission rod 17 away from the dual-head motor 16, and the second bevel gear 18 meshes with the first bevel gear 15.

[0045] Specifically, a feeding plate 19 is slidably connected to the upper end of the base plate 1, and two sets of feeding plates 19 are provided.

[0046] With the above structure, the automatic splicing device for white cardboard provided in this application, when the paper roll 8 in use is about to run out, places the beginning of another set of paper rolls 8 on the surface of the corresponding positioning plate 43, so that the beginning of the paper roll 8 covers the air hole 44. At this time, the vacuum pump 9 is started and the corresponding solenoid valve 11 is opened. At this time, the beginning of the paper roll 8 can be sucked onto the surface of the positioning plate 43. Then, adhesive is applied to the beginning of the paper roll 8. When the paper roll 8 in use is used up, the second roller 55 is no longer resisted by the paper roll 8. The connecting block 54 can be moved downward by the elastic force of the spring 56. At this time, the connecting plate 53 moves downward synchronously and presses the sensor 57. After the sensor 57 is pressed, the positioning plate 43 can be moved closer to the other set of positioning plates 43 through the first telescopic cylinder 42. At this time, the two sets of paper rolls 8 can be spliced ​​end to end.

[0047] Pulling the lever 21 can move the feeding plate 19 forward, allowing the paper roll 8 to be placed on top of the feeding plate 19. The dual-head motor 16 drives the transmission rod 17 to rotate, and the engagement of the second bevel gear 18 and the first bevel gear 15 causes the lead screw 14 to rotate. The rotation of the lead screw 14 moves the slider 6, allowing the position of the material rod 7 to be adjusted. Once the position of the material rod 7 is adjusted, the feeding plate 19 is pushed back to its original position, allowing the paper roll 8 to be installed on the side of the material rod 7. This structure makes it very convenient to install the paper roll 8.
