[0024] like Figure 1-6 As shown, a metal drum heat transfer printing device includes a first base 1 and a rolling mechanism 2. One end of the first base 1 is rotatably equipped with a driven roller 3 for hanging a roll of heat transfer film 21, and the other end of the first base 1 is rotatably equipped with a driving roller 4 for pulling the heat transfer film 21. A first motor 5 is fixedly mounted on the first base 1, and the output shaft of the first motor 5 is connected to one end of the driving roller 4 via a belt. The first base 1 has a through transfer opening located between the driving roller 4 and the driven roller 3. The heat transfer film 21 is located above the transfer opening, and the rolling mechanism 2 is located above the heat transfer film 21 above the transfer opening. A conveyor belt 6 is provided below the first base 1, and multiple fixtures 7 for carrying metal drums 22 are fixedly connected to the conveyor belt 6. When the conveyor belt 6 is running, the fixtures 7 pass sequentially below the transfer opening. In use, the metal drum 22 is placed on the fixture 7, the heat transfer film 21 roll is installed on the driven roller 3, and one end of the heat transfer film 21 is connected to the drive roller 4. The conveyor belt 6 drives the fixture 7 and the metal drum 22 to below the transfer opening. Under the traction of the drive roller 4, when the patterned part of the heat transfer film 21 reaches above the transfer opening, the conveyor belt 6 stops running. The rolling mechanism 2 presses the heat transfer film 21 down and attaches the pattern on the heat transfer film 21 to the surface of the metal drum 22. The first motor 5 drives the drive roller 4 to rotate and wraps the heat transfer film 21 after rolling and transfer onto the drive roller 4. The conveyor belt 6 starts running again and drives another metal drum 22 to the corresponding position. The above steps are repeated to continuously transfer the metal drum 22, avoiding downtime caused by picking up and putting down the metal drum 22.

[0025] In this embodiment, the rolling mechanism 2 includes a vertically arranged first cylinder 201. A mounting plate 202 is fixedly mounted on the output end of the first cylinder 201. A first roller 203 is rotatably mounted on the mounting plate 202, and the axis of the first roller 203 is parallel to the axis of the metal drum 22. When the first cylinder 201 extends, it drives the mounting plate 202 and the first roller 203 to move downwards. The first roller 203 presses down on the heat transfer film 21, ensuring full contact between the heat transfer film 21 and the surface of the metal drum 22, thus better adhering the pattern on the heat transfer film 21 to the surface of the metal drum 22.

[0026] In this embodiment, mounting brackets 8 are fixedly provided on both sides of the transfer opening. Each mounting bracket 8 includes two vertically spaced arms 801, with a first crossbeam 802 vertically fixed between the two arms 801. A first guide rail 9 is fixedly connected to the first crossbeam 802, and a first lead screw 10 is rotatably mounted on the first crossbeam 802. The first guide rail 9 is parallel to the first lead screw 10, and a first slider 11 is slidably connected to the first guide rail 9. The first slider 11 is threadedly connected to the first lead screw 10. A second motor 12 is fixedly mounted on the first crossbeam 802, and the output shaft of the second motor 12 is fixedly connected to one end of the first lead screw 10. The second motor 12 drives the first lead screw 10 to rotate, and the first lead screw 10 drives the first slider 11 to move along the first guide rail 9.

[0027] In this embodiment, a second crossbeam 13 is fixedly connected between the two first sliders 11. A vertically arranged second cylinder 14 is fixedly mounted on the second crossbeam 13. A heating component 15 is provided at the output end of the second cylinder 14. Specifically, the heating component 15 can be a hot air blower. The heating component 15 is used to heat the heat transfer film 21. The ink of the pattern on the heat transfer film 21 melts after being heated, which can make the ink of the pattern bond more firmly to the surface of the metal bucket 22, and it will not easily fall off in later use. The extension and retraction of the second cylinder 14 can change the distance between the heating component 15 and the heat transfer film 21, thereby controlling the degree of melting of the pattern ink. The first sliders 11 drive the second crossbeam 13 and the second cylinder 14 to move, which can adjust the relative distance between the heating component 15 and the first roller 203 to meet different production needs.

[0028] In this embodiment, a hydraulic cylinder 16 is fixedly mounted on the first base 1. The output end of the hydraulic cylinder 16 is rotatably connected to a first turntable 17. The first turntable 17 is detachably in contact with one end wall of the metal barrel 22. A sliding mechanism 18 is provided on the other side of the metal barrel 22. A third motor 19 is mounted on the sliding mechanism 18. A second turntable 20 is fixedly connected to the output shaft of the third motor 19. The second turntable 20 is detachably in contact with the other end wall of the metal barrel 22. When the first hydraulic cylinder 16 extends, the first turntable 17 contacts one end of the metal barrel 22. The sliding mechanism 18 drives the third motor 19 and the second turntable 20 to move, and the second turntable 20 contacts the other end of the metal barrel 22. When the third motor 19 rotates, it drives the metal barrel 22 to rotate, which can completely and evenly attach the pattern to the surface of the metal barrel 22.

[0029] In this embodiment, the sliding mechanism 18 includes a horizontally arranged second base 1801, two parallel second guide rails 1802 fixedly mounted on the second base 1801, a second lead screw 1803 rotatably connected to the second base 1801, a second slider 1804 slidably connected to the second guide rails 1802, the second slider 1804 being threadedly rotatably connected to the second lead screw 1803, the second slider 1804 being fixedly connected to a third motor 19, and a fourth motor 1805 fixedly mounted on the second base 1801. The output shaft of the fourth motor 1805 is fixedly connected to one end of the second lead screw 1803. The fourth motor 1805 drives the second lead screw 1803 to rotate, and the second lead screw 1803 drives the second slider 1804 to move along the second guide rails 1802. Specifically, as shown... Figure 6 As shown, when the second slider 1804 moves to the left, the third motor 19 and the second turntable 20 approach and contact the end wall of the metal barrel 22. When the second slider 1804 moves to the right, the second turntable 20 moves away from the end wall of the metal barrel 22, and the two disengage.

[0030] In this embodiment, the operator places the metal drum onto the fixture 7. The conveyor belt 6 moves the fixture 7 and the metal drum 22 to below the pattern on the heat transfer film 21 and then stops. The first turntable 17 and the second turntable 20 respectively abut against one end wall of the metal drum 22. The third motor 19 drives the metal drum 22 to rotate, and the first motor 5 drives the drive roller 4 to rotate and pull the heat transfer film 21 to move. The heating component 15 heats the heat transfer film 21, causing the ink of the pattern to melt. The first cylinder 201 extends, causing the first roller 203 to press down on the heat transfer film 21 and make the heat transfer film 21 contact the metal drum 22, attaching the pattern to the surface of the metal drum 22. The conveyor belt 6 continues to run, and the above steps are repeated for continuous production.
