[0034] Based on this, in the related art, manual operation requires more labor input, increases the labor cost in the production process, and at the same time has low efficiency, which is not conducive to large-scale production and cannot improve production efficiency.

[0035] Please refer to Figures 1-6 , a silk screen printing device for fragrance labels, including a mounting frame 1. A workbench 2 is fixedly connected to the top end of the mounting frame 1. A silk screen printing assembly 6 is arranged on the top end of the workbench 2, and a conveyor assembly 5 is arranged on the top end of the workbench 2. A transmission frame 7 is arranged on the top end of the workbench 2. The transmission frame 7 is located below the silk screen printing assembly 6. The silk screen printing assembly 6 includes a driving device 63. The driving device 63 is fixedly installed on the top end of the workbench 2. A movable frame 67 is installed at the outer end of the driving device 63. A first squeegee 65 and a second squeegee 66 are respectively installed at the bottom end of the movable frame 67. The driving device 63 drives the movable frame 67 to perform a horizontal reciprocating motion. The conveyor assembly 5 includes two rotating shafts 54, and a plurality of driving wheels 56 distributed at equal intervals are fixedly connected to the outer ends of the two rotating shafts 54.

[0036] A roller shaft 3 is rotatably connected to the outer end of the workbench 2, and a roller shaft 4 is rotatably connected to the top of the workbench 2. The roller shaft 4 is located above the transmission rack 7.

[0037] The transmission rack 7 includes a transmission plate 71. Extension plates 72 are fixedly connected to both ends of the transmission plate 71. The extension plates 72 are inclined. The transmission plate 71 is fixedly installed on the top of the workbench 2.

[0038] The process principle of fragrance printing is to encapsulate the fragrance into capsules and then incorporate it into the ink as needed. The key to this printing method lies in using the screen printing process because the fragrance capsule particles in the fragrance ink are relatively thick and cannot withstand excessive printing pressure. By screen printing, the damage of its fragrance capsules can be reduced. The fragrance ink is composed of fragrance capsules, adhesives, pigments, and other additives. Among them, the fragrance capsules are formed by dispersing the fragrance core material in the aqueous phase of a hydrophilic natural or synthetic polymer resin according to the principle of emulsification to form microcapsules containing fragrance. The diameter of these microcapsules is 10 - 30 mm, and the wall thickness is about 1 mm. Protected by the sachet, this fragrance can be preserved for a long time. Without breaking the sachet, the fragrance can be retained for several years. When the user touches and rubs the label, the fragrance capsules will break and emit fragrance.

[0039] The device in this solution is mainly used to print fragrance ink onto the label through the screen printing process. A workbench 2 is fixed to the top of the mounting frame 1. A conveying assembly 5 and a screen printing assembly 6 are respectively arranged on the top of the workbench 2. At the same time, a transmission rack 7 is also provided. The transmission rack 7 is located below the screen printing stencil 62. At the same time, a roller shaft 3 and a roller shaft 4 are rotatably connected to the mounting frame 1. The roller shaft 3 is located below the workbench 2 and is arranged at the notch of the workbench 2, while the roller shaft 4 is arranged on the top of the workbench 2, that is, above the transmission rack 7. The transmission rack 7 is mainly composed of a transmission plate 71 and extension plates 72 connected to both ends thereof. The transmission plate 71 is fixed to the workbench 2 and also fixed to the tops of two support frames 61, making the transmission plate 71 more resistant to pressure. Since the labels are connected together in a continuous long strip during mass production, through the cooperation of the roller shaft 3, the roller shaft 4, and the conveying assembly 5, they can be continuously printed by the screen printing assembly 6.

[0040] A conveying assembly 5 is installed on the transmission plate 71 arranged below the screen printing stencil 62. The squeegee 1 65 and the squeegee 2 66 arranged above the screen printing stencil 62 are controlled and driven by a driving device 63 and a cylinder device 64. The servo motor 51 drives the driving wheel 56 to rotate, moving the label to below the screen printing stencil 62. Then the driving device 63 drives the squeegee 2 66 and the squeegee 1 65 to transfer the ink on the screen printing stencil 62 to the label through pressure. Through the cooperation of the screen printing assembly 6 and the conveying assembly 5, automatic screen printing can be achieved, thereby improving the printing efficiency and reducing the labor cost.

[0041] Optionally, in some embodiments, refer to Figure 3 , two cylinder devices 64 are installed at the top of the movable frame 67. Both of the two cylinder devices 64 are externally connected to a gas supply system. The two cylinder devices 64 are respectively connected to the first squeegee 65 and the second squeegee 66, and the two cylinder devices 64 respectively drive the first squeegee 65 and the second squeegee 66 to move up and down.

[0042] The screen printing assembly 6 further includes two support frames 61. A screen printing stencil 62 is fixedly connected to the outer end of the driving device 63. The screen printing stencil 62 is located above the transfer plate 71. Both of the two support frames 61 are fixedly installed at the top of the workbench 2, and both of the two support frames 61 are fixedly connected to the bottom end of the transfer plate 71.

[0043] In this solution, the driving device 63 and the two support frames 61 are both fixed on the workbench 2. A screen printing stencil 62 is fixed to the outer end of the driving device 63. The screen printing stencil 62 is also located above the transfer plate 71, and a gap through which the label can pass is provided between the screen printing stencil 62 and the transfer plate 71. A screw rod is provided inside the driving device 63 to drive the movable frame 67 to perform a reciprocating lateral movement. At the same time, two cylinder devices 64 are installed at the top of the movable frame 67. The cylinder devices 64 are externally connected to a gas supply system to provide compressed gas. The first squeegee 65 and the second squeegee 66 are connected to the output ends of the two cylinder devices 64. The working mode is that when the conveying assembly 5 drives the label to move below the screen printing stencil 62, the cylinder device 64 drives the first squeegee 65 to move downward. At this time, the second squeegee 66 does not move downward and does not contact the screen printing stencil 62. By driving the movable frame 67 to move laterally through the driving device 63, the first squeegee 65 can be moved while squeezing the ink, and the ink is printed on the label through the screen printing stencil 62. At this time, the ink on the screen printing stencil 62 will be on one side of the moving direction of the first squeegee 65, that is, the ink will always be between the first squeegee 65 and the second squeegee 66. Then, the cylinder device 64 is driven to move the first squeegee 65 upward, and the second squeegee 66 moves downward. The conveying assembly 5 starts to drive the printed label to move forward. A new label moves below the screen printing stencil 62 again, and then the driving device 63 is driven to move the movable frame 67, so that the second squeegee 66 squeezes the ink again. By working in this reciprocating manner, the labels can be screen printed in batches, thereby improving the printing efficiency.

[0044] Optionally, in some embodiments, refer to Figure 5 and Figure 6, the conveying component 5 further includes a servo motor 51 and four fixing brackets 55. The servo motor 51 is fixedly installed at the top end of the workbench 2. The output end of the servo motor 51 is fixedly connected with a driving pulley 52. One end of each of the two rotating shafts 54 is fixedly connected with a driven pulley 53. Two belts 510 are sleeved outside the driving pulley 52. The two driven pulleys 53 are respectively in transmission connection with the driving pulley 52 through the two belts 510. The four fixing brackets 55 are all fixedly installed at the outer ends of the transmission plate 71. The rotating shaft 54 penetrates through the two fixing brackets 55.

[0045] A plurality of sliding grooves 59 are formed in the outer end of the driving wheel 56. Two telescopic springs 58 are fixedly installed on the inner side wall of the sliding groove 59. The other end of the telescopic spring 58 is fixedly connected with a friction block 57. The friction block 57 is slidably connected with the sliding groove 59. Anti-slip lines are arranged on the outer end of the friction block 57, and the friction block 57 is made of rubber material.

[0046] The servo motor 51 mentioned above is fixed on the top of the workbench 2. The driving pulley 52 is fixed at the output end of the servo motor 51. The four fixing brackets 55 are fixed in pairs on both sides of the transmission plate 71. The rotating shaft 54 penetrates through the two fixing brackets 55 respectively, so that the rotating shaft 54 can rotate. A driven pulley 53 is fixed at one end of the rotating shaft 54. The two driven pulleys 53 are in transmission connection with the driving pulley 52 through the belt 510, so that the servo motor 51 can drive the rotating shaft 54 to rotate through the driving pulley 52, the belt 510 and the driven pulley 53. A plurality of driving wheels 56 are fixed on the rotating shaft 54. A plurality of sliding grooves 59 are arranged at the outer end of the driving wheel 56. A friction block 57 is arranged in the sliding groove 59 at the outer end of the driving wheel 56. Anti-slip lines are arranged on the outer end of the friction block 57, and it is made of rubber material itself. Two telescopic springs 58 are also fixed inside the sliding groove 59. The rotating shaft 54 drives the driving wheel 56 to rotate. At the same time, the telescopic spring 58 pushes the friction block 57 outwards through its own acting force, so that the surface of the friction block 57 can contact the label, and the label can be pushed forward through the frictional force. Since there are two groups of driving wheels 56 driving the label to move at the same time, the label can move stably, and the probability of slipping is reduced. The servo motor 51 is driven by a servo controller, so that the rotation stroke can be accurately controlled, and each time the servo motor 51 rotates, the printed label can be accurately conveyed away, and the new label moves to the lower part of the screen printing stencil 62.

[0047] Working principle: When using this device to print labels, first, the long strip-shaped labels need to be passed through from the bottom of roller 3, and guided along the transfer plate 71 until it reaches below roller 4. At this time, the silk screen printing assembly 6 can be started. The cylinder device 64 will drive the first squeegee 65 to move downward. By driving the movable frame 67 through the driving device 63, the first squeegee 65 can squeeze the ink while moving, and the ink is printed on the label through the silk screen plate 62. Then, the cylinder device 64 drives the first squeegee 65 to move upward, and the second squeegee 66 moves downward. The conveying assembly 5 starts to drive the printed label to move forward. Multiple driving wheels 56 are fixed on the rotating shaft 54. By driving the rotation of the driving wheels 56 through the rotating shaft 54, the surface of the friction block 57 can be brought into contact with the label, and the label is pushed forward through the frictional force. The new label then moves below the silk screen plate 62, and the driving device 63 drives the movable frame 67 to move, so that the second squeegee 66 squeezes the ink again. By working in this reciprocating manner, the labels can be silk screen printed in batches.

[0048] The above is only the preferred specific implementation manner of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improved concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
