DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See Figures 1 to 5 In an embodiment of the present utility model, a self-adhesive label printing device includes a base 1, a rotating frame 3, an arc guide groove 24, a rotary drive assembly, a telescopic printing head assembly and a transmission assembly;

[0026] The base 1 is fixedly connected to two sets of symmetrically arranged fixed frames 2, and the base 1 is fixedly connected to an ink pad 20, which is arranged in the middle between the fixed frames 2, and the rotating frame 3 is arranged between the two sets of fixed frames 2;

[0027] The rotation drive assembly is installed between the rotating frame 3 and the fixed frame 2, so that the rotating frame 3 is driven to rotate by the rotation drive assembly;

[0028] The telescopic printing head assembly is provided with multiple groups, and the multiple groups of telescopic printing head assemblies are equidistantly installed in a circumferential distribution inside the rotating frame 3;

[0029] The conveying assembly is installed on the base 1 and is used to convey the label;

[0030] The telescopic printing head assembly comprises a sliding telescopic rod 7 slidably connected to the rotating frame 3, a connecting plate 9 is fixedly connected to one end of the sliding telescopic rod 7 away from the rotating frame 3, and a driving frame 11 is fixedly connected to the other end of the sliding telescopic rod 7. A first spring 8 sleeved on the sliding telescopic rod 7 is provided between the connecting plate 9 and the rotating frame 3, a telescopic clamping frame 10 is slidably connected to the outer wall of the connecting plate 9, a positioning cylinder 13 is fixedly connected to the telescopic clamping frame 10, a positioning rod 12 is fixedly connected to the connecting plate 9, the positioning rod 12 is slidably connected to the positioning cylinder 13, and a second spring 14 is sleeved on the outer wall of the positioning cylinder 13 and the positioning rod 12, a mounting plate 15 is fixedly connected to the connecting plate 9, a printing plate 16 is fixedly connected to the mounting plate 15, and the printing plate 16 cooperates with the telescopic clamping frame 10;

[0031] The fixing frame 2 is fixedly connected to a mounting frame 21, a connecting shaft 22 is fixedly connected to the mounting frame 21, a mounting seat 23 is fixedly connected to the connecting shaft 22, an arc guide groove 24 is fixedly connected to the mounting seat 23, a stepped groove 25 is provided at the bottom of the arc guide groove 24, and connecting frames 26 are fixedly connected to both sides of the driving frame 11, and a guide rod 27 is rotatably connected to the connecting frame 26, and the guide rod 27 cooperates with the arc guide groove 24;

[0032] The utility model drives the label paper tape to be transported above the ink pad 20 through the conveying assembly, and during this process, the rotating frame 3 is driven to rotate by the rotary drive assembly, and the rotating frame 3 drives the multiple groups of telescopic printing head assemblies to rotate synchronously. During this process, the guide rod 27 in the telescopic printing head assembly and the circular arc guide groove 24 are in relative rolling contact. At the same time, the elastic push of the first spring 8 keeps the guide rod 27 always in contact with the inner wall of the circular arc guide groove 24.

[0033] When the guide rod 27 moves from the inside of the stepped groove 25 to the outside of the stepped groove 25, the guide rod 27 drives the driving frame 11 to move toward the center of the rotating frame 3 through the connecting frame 26 under the drive of the arc guide groove 24, and the driving frame 11 drives the connecting plate 9 to retract through the sliding telescopic rod 7, and the connecting plate 9 drives the telescopic clamping frame 10 and the printing plate 16 to retract synchronously in the direction away from the ink pad 20, and at the same time compresses the first spring 8. When the next group of guide rods 27 moves from the outside of the stepped groove 25 to the inside of the stepped groove 25, the first spring 8 releases elastic energy to drive the connecting plate 9 to extend, and the connecting plate 9 drives the telescopic clamping frame 10 and the printing plate 16 to extend synchronously in the direction close to the ink pad 20. In this process, the telescopic clamping frame 10 and the ink pad 20 are first pushed by the second spring 14 to cooperate with each other to elastically clamp the label paper tape, and then the printing plate 16 continues to extend, thereby printing the label paper tape;

[0034] Then, as the rotating frame 3 continues to rotate, the device repeats the previous process, thereby realizing automatic printing of the label paper tape.

[0035] In one embodiment of the present invention, see Figures 1 to 5 The mounting seat 23 is rotatably connected with an ink cartridge 28, and the ink cartridge 28 is rotatably connected with an ink inlet tube 29 through the mounting seat 23. The printing plate 16 is fixedly connected with a conduit 19, and the conduit 19 is connected to the ink cartridge 28. The utility model continuously supplies ink to the printing plate 16 through the arrangement of the conduit 19 and the ink cartridge 28.

[0036] In one embodiment of the present invention, see Figures 1 to 5 The rotation drive assembly includes a ring gear 4 fixedly connected to both sides of the rotating frame 3. The fixed frame 2 is rotatably connected to multiple groups of circumferentially distributed gears 5, and the gears 5 and the ring gear 4 are engaged with each other. A first motor 6 is fixedly connected to the fixed frame 2, and the output shaft of the first motor 6 is fixedly connected to the gear 5. The rotation drive assembly first supports and fixes the rotating frame 3 through the mutual engagement of multiple groups of gears 5 and the ring gear 4, and then can drive a group of gears 5 to rotate through the first motor 6. The gears 5 drive the gears 5 to rotate by engaging with the ring gear 4, and the ring gear 4 drives the rotating frame 3 to rotate in steps.

[0037] In one embodiment of the present invention, see Figures 1 to 5 The transmission component includes a unwinding drum 31 rotatably connected to one end of the base 1, and the other end of the base 1 is rotatably connected to the unwinding drum 31. A second motor 32 is fixedly connected to one side of the winding drum 30. The output shaft of the second motor 32 is fixedly connected to the winding drum 30. The transmission component rewinds the unprinted label paper tape through the unwinding drum 31 and rewinds the printed label paper tape through the winding drum 30. At the same time, the second motor 32 drives the winding drum 30 to rotate in steps, thereby pulling the paper tape.

[0038] In one embodiment of the present invention, see Figures 1 to 5 Two sets of guide rollers 33 rotatably connected to the base 1 are arranged between the unwinding drum 31 and the winding drum 30. The conveying assembly guides the conveying direction of the label paper tape through the setting of the guide rollers 33, thereby avoiding the paper tape tilting caused by the change in the diameter of the unwinding drum 31 and the winding drum 30, affecting the printing effect of the equipment.
