Description

Technical Field

[0001] The present application relates to the field of label printing, and particularly to a printing label correction device. Background Art

[0002] The extensive application of labels and the continuous development of label varieties have naturally promoted the development of label printing technology. Label printing covers all printing methods such as flat, convex, concave, and screen printing, and the application situations in different countries are not the same.

[0003] In the prior art, after long-term production, the label is prone to deviation. For example, it starts to be printed in the middle of the printing roller and the pressing roller, but after long-term production and use, it may deviate from the middle position, resulting in a decline in printing quality, poor products, and the need for re-production, causing waste of resources.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0005] In order to solve the problem that the label is prone to deviation during the production process, the present application provides a printing label correction device.

[0006] A printing label correction device provided by the present application adopts the following technical solution:

[0007] A printing label correction device includes a connection seat. One side inside the connection seat is rotatably connected with a pressing roller, and one side inside the connection seat corresponding to the pressing roller is rotatably connected with a printing roller. A calibration sleeve is slidably connected inside the connection seat through the pressing roller and the printing roller. One side inside the connection seat is rotatably connected with a bidirectional threaded rod, and the bidirectional threaded rod extends outside the connection seat. Both sides of the outer wall of the bidirectional threaded rod are threadedly connected with moving blocks. One side of the outer wall of each moving block is fixedly connected with a connecting block, and the moving blocks are connected to the calibration sleeve through the connecting blocks.

[0008] Preferably, both sides inside the connection seat corresponding to the bidirectional threaded rod are fixedly connected with connecting rods. Both sides of the outer wall of each connecting rod are slidably connected with sliding sleeves. One side of the outer wall of each sliding sleeve is fixedly connected with a fixing rod, and the sliding sleeves are connected to the moving blocks through the fixing rods.

[0009] Preferably, one side of the side surface of the connection seat is fixedly connected with a second servo motor. The driving end of the second servo motor is fixedly connected to one side of the bidirectional threaded rod. One side of the side surface of the connection seat is fixedly connected with a first servo motor. The driving end of the first servo motor penetrates the inner wall of the connection seat and is fixedly connected to one side of the printing roller.

[0010] Preferably, a second gear is rotatably connected to the side surface of the connecting seat through the pressure roller, a first gear is rotatably connected to the side surface of the connecting seat through the printing roller, and the second gear and the first gear are tightly engaged with each other.

[0011] Preferably, tension rollers are rotatably connected to both sides inside the connecting seat, support blocks are fixedly connected to both sides of the outer surface of the connecting seat, and a winding roller is arranged on the outer surface of the connecting seat through the two support blocks.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. The second servo motor drives the bidirectional threaded rod to rotate. The two fixed rods on both sides connect the sliding sleeves on both sides with the moving block, restricting the moving direction of the moving block. Then, when the bidirectional threaded rod rotates, it can only drive the moving blocks on both sides to move towards each other. The connecting block connects the moving block with the calibration sleeve, driving the two calibration sleeves to move towards each other along the outer walls of the pressure roller and the printing roller, so as to calibrate the label through the two calibration sleeves; compared with the prior art, it has the effect of preventing the label from running off during the production process and playing a role in correcting and limiting.

[0014] 2. Since both ends of the label are in contact with the tension rollers, the label is in a taut state. The first servo motor drives the printing roller to rotate to print the label. The second gear and the first gear are engaged with each other, thereby driving the pressure roller to rotate simultaneously, making the label closely adhere to the printing roller, and avoiding the phenomenon of incomplete printing; compared with the prior art, it has the effect of reducing defective products and improving the printing quality.

[0020] The following will further describe this application in detail with reference to the Figures 1-4 drawings.

[0021] An embodiment of this application discloses a printing label correction device. Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a printing label correction device includes a connecting seat 1. One side inside the connecting seat 1 is rotatably connected with a pressing roller 5, and one side inside the connecting seat 1 corresponding to the pressing roller 5 is rotatably connected with a printing roller 6. By arranging the pressing roller 5 above the printing roller 6, the pressing roller 5 applies a downward pressure, which is convenient for the printing roller 6 to print the label. A calibration sleeve 7 is slidably connected inside the connecting seat 1 through the pressing roller 5 and the printing roller 6. Since the size of the calibration sleeve 7 fits the sizes of the pressing roller 5 and the printing roller 6, the calibration sleeve 7 can freely slide on the outer walls of the pressing roller 5 and the printing roller 6 without interfering with their normal operation, so that the label passes through the gap between the two calibration sleeves 7 to calibrate the label and avoid printing errors. One side inside the connecting seat 1 is rotatably connected with a bidirectional threaded rod 14, and the bidirectional threaded rod 14 extends outside the connecting seat 1. Among them, the two sides of the outer wall of the bidirectional threaded rod 14 are helically symmetric with the center point of the bidirectional threaded rod 14 as the mirror image, and the helical angles are both set to twenty degrees. Both sides of the outer wall of the bidirectional threaded rod 14 are threadedly connected with moving blocks 17. Among them, the two moving blocks 17 are symmetric with the center point of the bidirectional threaded rod 14 as the mirror image, and the screw lift of the bidirectional threaded rod 14 is less than the equivalent friction angle of the screw pair formed by the bidirectional threaded rod 14 and the moving block 17, forming self-locking to prevent movement due to external reasons. One side of the outer wall of each moving block 17 is fixedly connected with a connecting block 12, and each moving block 17 is connected to the calibration sleeve 7 through the connecting block 12. By connecting the moving block 17 and the calibration sleeve 7 through the connecting block 12, when the bidirectional threaded rod 14 rotates, the two moving blocks 17 on both sides move towards each other, and then drive the two calibration sleeves 7 on both sides to move towards each other along the outer walls of the pressing roller 5 and the printing roller 6, so that the label is calibrated by the two calibration sleeves 7, achieving the effect of adjusting the positions of the two calibration sleeves 7 according to the size of the label.

[0022] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4, on both sides corresponding to the two-way threaded rod 14 inside the connecting seat 1, connecting rods 9 are fixedly connected. On both sides of the outer wall of the connecting rod 9, sliding sleeves 8 are slidably connected. On one side of the outer wall of each sliding sleeve 8, a fixed rod 16 is fixedly connected. The sliding sleeves 8 are connected to the moving blocks 17 through the fixed rods 16. Among them, the sliding sleeves 8 and the moving blocks 17 correspond to each other. The two sliding sleeves 8 and the moving blocks 17 are connected through the fixed rods 16 on both sides, so as to limit the moving direction of the moving blocks 17, so that the rotation of the two-way threaded rod 14 can only drive the two moving blocks 17 to move towards each other.

[0023] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , on one side of the side surface of the connecting seat 1, a second servo motor 10 is fixedly connected. The driving end of the second servo motor 10 is fixedly connected to one side of the two-way threaded rod 14. On one side of the side surface of the connecting seat 1, a first servo motor 4 is fixedly connected. The driving end of the first servo motor 4 penetrates the inner wall of the connecting seat 1 and is fixedly connected to one side of the printing roller 6. By connecting the driving end of the second servo motor 10 to the two-way threaded rod 14, the second servo motor 10 drives the two-way threaded rod 14 to rotate. By connecting the first servo motor 4 to the printing roller 6, the first servo motor 4 drives the printing roller 6 to rotate to print the label.

[0024] Refer to Figure Figure 2 and Figure 3 , on the side surface of the connecting seat 1, a second gear 13 is rotatably connected through a pressure roller 5, and a first gear 11 is rotatably connected through a printing roller 6 on the side surface of the connecting seat 1. The second gear 13 and the first gear 11 are tightly meshed. By connecting the pressure roller 5 to the second gear 13, by connecting the printing roller 6 to the first gear 11, and the second gear 13 and the first gear 11 are meshed, the first servo motor 4 drives the printing roller 6 to rotate, and at the same time drives the pressure roller 5 to rotate. Thus, the printing roller 6 prints the label, and at the same time the pressure roller 5 makes the label close to the printing roller 6, avoiding the phenomenon of incomplete printing. When producing the label, the printing roller 6 is used as the driving roller and the pressure roller 5 is used as the driven roller. During production, only the first servo motor 4 needs to be started, improving the reliability.

[0025] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , on both sides inside the connecting seat 1, tension rollers 15 are rotatably connected. On both sides of the outer surface of the connecting seat 1, support blocks 2 are fixedly connected. A winding roller 3 is arranged on the outer surface of the connecting seat 1 through the two support blocks 2. By arranging the two tension rollers 15, the label is in a taut state during printing, improving the printing efficiency. After printing, it is wound by the winding roller 3 installed at the front end of the connecting seat 1.

[0026] The implementation principle of a printing label correction device in an embodiment of the present application is as follows: When producing labels, first, the label is passed through the gap between the pressure roller 5 and the printing roller 6, and both ends of the label are in contact with the tension roller 15, so that the label is in a taut state. The second servo motor 10 drives the bidirectional threaded rod 14 to rotate. The two sliding sleeves 8 on both sides are connected to the moving block 17 through the fixing rods 16 on both sides, so as to limit the moving direction of the moving block 17. Then, the rotation of the bidirectional threaded rod 14 can only drive the two moving blocks 17 to move towards each other. The moving block 17 is connected to the calibration sleeve 7 through the connecting block 12, so as to drive the two calibration sleeves 7 to move towards each other along the outer walls of the pressure roller 5 and the printing roller 6, so as to calibrate the label through the two calibration sleeves 7. Finally, the first servo motor 4 drives the printing roller 6 to rotate to print the label. The second gear 13 meshes with the first gear 11, so as to drive the pressure roller 5 to rotate at the same time, making the label close to the printing roller 6, and avoiding the phenomenon of incomplete printing.
