[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of an automatic printing device for rubber tube marking, comprising a body 1, a U-shaped slide plate 12 fixedly connected to the top rear side of the body 1, elongated U-shaped plates 20 fixedly connected to the upper and lower sides of the outer wall of the U-shaped slide plate 12, a sliding block 10 slidably connected inside the elongated U-shaped plate 20, a U-shaped piece 8 fixedly connected to the front side of the outer wall of the sliding block 10, a movable short plate 9 slidably connected inside the U-shaped piece 8, the U-shaped piece 8 serving to limit the movement trajectory of the movable short plate 9, and a rubber head plate 7 fixedly connected to the bottom of the movable short plate 9. A long column 22 is rotatably connected to the rear side of the outer wall of the 2. A gear 23 is fixedly connected to the rear end of the outer wall of the long column 22. The long column 22 serves to fix the gear 23 so that it can rotate. An inner sliding groove connecting rod 11 is fixedly connected to the front side of the outer wall of the long column 22. A sliding block 28 is slidably connected inside the inner sliding groove connecting rod 11. The long column 22 is fixedly connected to the middle of the sliding block 28. The front end of the outer wall of the long column 22 is fixedly connected to the rear side of the outer wall of the movable short plate 9. The outer wall of the long column 22 is slidably connected to the interior of the U-shaped sliding groove plate 12. The rear end of the outer wall of the U-shaped sliding groove plate 12... A long inner sliding plate 25 is fixedly connected to the side. A double-sided moving rack 21 is slidably connected inside the long inner sliding plate 25. A motor 26 is fixedly connected to the rear side of the outer wall of the long inner sliding plate 25. A gear 27 is fixedly connected to the output end of the motor 26. The gear 27 meshes with the upper end of the double-sided moving rack 21. By turning on the motor 26, the gear 27 can be driven to rotate. When the gear 27 rotates, it will mesh with the upper end of the double-sided moving rack 21, thereby driving the double-sided moving rack 21 to move. The double-sided moving rack 21 meshes with the lower end of the gear 23. The machine body 1 is connected to the rubber head plate 7, which is equipped with a stamp 13. Multiple clamping mechanisms 2 are installed at equal intervals on the top of the machine body 1. The clamping mechanisms 2 are used to clamp and fix stamps 13 of different sizes for use. Multiple fans 5 are fixedly connected at equal intervals on the left and right sides of the outer wall of the machine body 1. The fans 5 serve to dissipate heat and blow air. Multiple batteries 6 are fixedly connected at equal intervals on the left and right sides of the outer wall of the machine body 1. A hollow box 17 is fixedly connected to the left side of the outer wall of the machine body 1. A drawer 16 is slidably connected inside the hollow box 17. The drawer 16 can facilitate the storage of tools for daily use and maintenance for future use.

[0032] Specifically, by turning on the motor 26, the output end is driven to rotate the gear 27. Since the gear 27 is meshed with the upper end of the double-sided moving rack 21, the rotation of the gear 27 will drive the double-sided moving rack 21 to slide inside the elongated inner slide plate 25. Because the double-sided moving rack 21 is meshed with the lower end of the gear 23, when the double-sided moving rack 21 slides, it will drive the gear 23 to rotate. The gear 23 is fixed to the rear end of the outer wall of the elongated column 22, and the elongated column 22 will rotate together with the gear 23. Since the inner slide connecting rod 11 is fixedly connected to the front side of the outer wall of the elongated column 22, and the inner slide connecting rod 11 is slidably connected to the sliding block 28, the middle part of the sliding block 28 is fixedly connected to the elongated column 22, and the outer wall of the elongated column 22 is slidably connected to the inside of the U-shaped slide plate 12, the rotation of the elongated column 22 will drive the elongated column 22 to slide along the inside of the U-shaped slide plate 12, thereby driving the front end of the elongated column 22 to be fixed. The connected movable short plate 9 moves, and the bottom of the movable short plate 9 is fixedly connected to the glue head plate 7, so the glue head plate 7 will move synchronously. The movable short plate 9 slides inside the U-shaped piece 8. When a stamping operation is required, the movable short plate 9 drives the glue head plate 7 to move downward, so that multiple stamps 13 installed inside the glue head plate 7 contact the surfaces of multiple glue tubes below for printing. After stamping, the movable short plate 9 drives the glue head plate 7 to move upward, so that multiple stamps 13 leave the surfaces of the glue tubes, completing the stamping. This achieves the effect of stamping multiple glue tubes at one time. Multiple fans 5 are fixedly connected at equal intervals on both the left and right sides of the outer wall of the machine body 1. The fans 5 serve the function of heat dissipation and air blowing. Multiple batteries 6 are fixedly connected at equal intervals on both the left and right sides of the outer wall of the machine body 1. A hollow box 17 is fixedly connected to the left side of the outer wall of the machine body 1. A drawer 16 is slidably connected inside the hollow box 17. The drawer 16 can facilitate the storage of tools for daily use and maintenance for future use.

[0033] Reference Figure 1 and Figure 5The clamping mechanism 2 includes a ring 201, which is equidistantly mounted on the top of the body 1. Multiple rotating short columns 209 are equidistantly rotatably connected around the top of the ring 201. An elongated plate 208 is fixedly connected to the top of each rotating short column 209. A circular inner groove ring 206 is rotatably connected to the top of the ring 201. Multiple hollow plates 207 are slidably connected around the inner wall of the circular inner groove ring 206. Multiple rotating columns 204 are equidistantly rotatably connected around the top of the circular inner groove ring 206. The bottom end of each rotating column 204 is rotatably connected to the top of the hollow plate 207. The outer wall of the elongated plate 208 is slidably connected to the interior of the hollow plate 207. A spring plate 205 is fixedly connected to each adjacent side of the outer wall of the elongated plate 208, providing adaptive clamping. For the purpose of fixing, a long short plate 203 is fixedly connected to the top of the ring 201, and a threaded rod 202 is rotatably connected to the middle of the long short plate 203. A movable plate 210 is threadedly connected to the outer wall of the threaded rod 202. By rotating the threaded rod 202, the movable plate 210 on the outer wall can be moved. The left side of the outer wall of the movable plate 210 is fixedly connected to the outer wall of the circular inner groove ring 206. A handle 18 is fixedly connected to the left side of the outer wall of the drawer 16. The handle 18 facilitates the opening and closing of the drawer 16 for use by the staff. An anti-slip sleeve 19 is fixedly connected to the outer wall of the handle 18. A screw 15 is threadedly connected to the left side of the outer wall of the machine body 1. A warning sign 14 is threadedly connected to the outer wall of the screw 15. The warning sign 14 can serve as a warning to the surrounding personnel.

[0034] Specifically, rotating the threaded rod 202 causes the movable plate 210 on the outer wall to move. Since the movable plate 210 and the threaded rod 202 are threadedly connected, when the threaded rod 202 is rotated, the movable plate 210 will move along the outer wall of the threaded rod 202. Because the left side of the outer wall of the movable plate 210 is fixedly connected to the outer wall of the circular inner groove ring 206, the linear movement of the movable plate 210 will cause the circular inner groove ring 206 to rotate at the top of the ring 201. Multiple hollow plates 207 are slidably connected around the inner wall of the circular inner groove ring 206, and multiple rotating pillars 204 are equidistantly rotatably connected around the top of the circular inner groove ring 206. The bottom end of each rotating pillar 204 is rotatably connected to the top of the hollow plate 207. Therefore, when the circular inner groove ring 206 rotates, the rotating pillars 204 will cause the hollow plates 207 to slide along the inner wall of the circular inner groove ring 206. The outer side of the elongated plate 208... The wall is slidably connected to the interior of the hollow plate 207. At the same time, the elongated plate 208 is rotatably connected to the top of the ring 201 via the rotating short column 209. Therefore, the sliding of the hollow plate 207 will push the elongated plate 208 to rotate around the rotating short column 209. Finally, when the elongated plate 208 rotates towards the center of the ring 201, it will drive the spring plate 205 on the adjacent side of the outer wall to gradually approach and clamp the stamp 13 placed at the center of the ring 201. The elasticity of the spring plate 205 is used to stably clamp the stamps 13 of different sizes. A handle 18 is fixedly connected to the left side of the outer wall of the drawer 16. The handle 18 can facilitate the opening and closing of the drawer 16 for use by the staff. An anti-slip sleeve 19 is fixedly connected to the outer wall of the handle 18. A screw 15 is threadedly connected to the left side of the outer wall of the machine body 1. A warning sign 14 is threadedly connected to the outer wall of the screw 15. The warning sign 14 can serve as a warning to the surrounding personnel.

[0035] Reference Figure 1 and Figure 2 Support rods 3 are fixedly connected to the four corners of the bottom of the machine body 1. The bottom end of the support rods 3 is fixedly connected to the fixing blocks 4. The fixing blocks 4 can support the machine body 1 away from the ground and prevent the machine body 1 from being damaged after prolonged contact with the ground. A circular handle 24 is fixedly connected to the front end of the outer wall of the threaded rod 202. The circular handle 24 can facilitate the operator to rotate the threaded rod 202. A protective sleeve 29 is fixedly connected to the outer wall of the circular handle 24.

[0036] Specifically, support rods 3 are fixedly connected to the four corners of the bottom of the machine body 1. The bottom end of the support rods 3 is fixedly connected to the fixing blocks 4. The fixing blocks 4 can support the machine body 1 away from the ground and prevent the machine body 1 from being damaged after prolonged contact with the ground. A circular handle 24 is fixedly connected to the front end of the outer wall of the threaded rod 202. The circular handle 24 can facilitate the operator to rotate the threaded rod 202. A protective sleeve 29 is fixedly connected to the outer wall of the circular handle 24.

[0037] Working principle: By turning on the motor 26, the output end drives the gear 27 to rotate. Since the gear 27 meshes with the upper end of the double-sided moving rack 21, the rotation of the gear 27 drives the double-sided moving rack 21 to slide inside the elongated inner slide plate 25. Because the double-sided moving rack 21 meshes with the lower end of the gear 23, when the double-sided moving rack 21 slides, it drives the gear 23 to rotate. The gear 23 is fixed to the rear end of the outer wall of the elongated column 22, and the elongated column 22 will rotate together with the gear 23. Since the inner slide connecting rod 11 is fixedly connected to the front side of the outer wall of the elongated column 22, and the inner slide connecting rod 11 is slidably connected to the sliding block 28, the middle of the sliding block 28 is fixedly connected to the elongated column 22, and the outer wall of the elongated column 22 is slidably connected to the inside of the U-shaped slide plate 12, the rotation of the elongated column 22 will drive the gear 23 to rotate. The movable elongated column 22 slides along the inside of the U-shaped slide plate 12, thereby driving the movable short plate 9, which is fixedly connected to the front end of the elongated column 22, to move. The bottom of the movable short plate 9 is fixedly connected to the rubber head plate 7, so the rubber head plate 7 will move synchronously. The movable short plate 9 slides inside the U-shaped piece 8. When a stamping operation is required, the movable short plate 9 drives the rubber head plate 7 to move downward, so that multiple stamps 13 installed inside the rubber head plate 7 contact the surfaces of multiple rubber tubes below for printing. After stamping is completed, the movable short plate 9 drives the rubber head plate 7 to move upward, so that multiple stamps 13 leave the surface of the rubber tubes, completing the stamping. This achieves the effect of stamping multiple rubber tubes at one time, thus avoiding the problem of extending the overall production cycle due to the inability to meet the needs of mass production printing, which in turn causes inconvenience to subsequent work.

[0038] The rotating threaded rod 202 drives the moving plate 210 on the outer wall to move. Since the moving plate 210 and the threaded rod 202 are threadedly connected, when the threaded rod 202 is rotated, the moving plate 210 will move along the outer wall of the threaded rod 202. Because the left side of the outer wall of the moving plate 210 is fixedly connected to the outer wall of the circular inner groove ring 206, the linear movement of the moving plate 210 will cause the circular inner groove ring 206 to rotate at the top of the ring 201. Multiple hollow plates 207 are slidably connected around the inner wall of the circular inner groove ring 206, and multiple rotating pillars 204 are equidistantly rotatably connected around the top of the circular inner groove ring 206. The bottom end of each rotating pillar 204 is rotatably connected to the top of the hollow plate 207. Therefore, when the circular inner groove ring 206... During rotation, the hollow plate 207 slides on the inner wall of the circular inner groove ring 206 via the rotating column 204. The outer wall of the elongated plate 208 is slidably connected to the inside of the hollow plate 207. At the same time, the elongated plate 208 is rotatably connected to the top of the ring 201 via the rotating short column 209. Therefore, the sliding of the hollow plate 207 will push the elongated plate 208 to rotate around the rotating short column 209. Finally, when the elongated plate 208 rotates towards the center of the ring 201, it will cause the spring plate 205 on the adjacent side of the outer wall to gradually approach and clamp the stamp 13 placed at the center of the ring 201. The elasticity of the spring plate 205 is used to stably clamp stamps 13 of different sizes, thereby achieving the function of adaptive adjustment of clamping according to the size of the stamp 13.
