[0002] As a convenient and environmentally friendly label form, self-adhesive labels are widely used in the identification and packaging of various products. The unique self-adhesive properties and the convenience of not requiring additional pasting tools enable self-adhesive labels to significantly save time and cost during the processing process.

[0003] However, in the coding and drying process of self-adhesive labels, a combination of a heating plate and a fan is usually relied on to directly blow hot air to dry the label surface. For example, a self-adhesive label coding drying device with a publication number of CN215590283U in the prior art can achieve rapid drying of the label and purify the gas after drying. However, the direct use of hot air to dry the ink after coding can easily cause the undried ink to be blown away, thereby affecting the clarity and quality of the coding.

[0034] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1-Figure 8 As shown, the method of directly using hot air to dry the ink after coding in the prior art easily causes the undried ink to be blown away, greatly affecting the clarity and quality of the coding. The following solution can be used to solve the problem;

[0036] In the present embodiment, a self-adhesive label coding drying structure comprises a drying box 1, and a feed port 11 and a discharge port 12 which are connected to each other and are located on one side of the drying box 1. The feed port 11 is located above the discharge port 12, so as to facilitate effective coding processing of the self-adhesive label before it enters the drying box 1. A drying conveying wheel 2 is rotatably installed inside the drying box 1. The self-adhesive label enters the drying box 1 and passes out after being guided by the drying conveying wheel 2. With the help of the rotation of the drying conveying wheel 2 and the external winding device, the self-adhesive label is conveyed. One end of the self-adhesive label extends into the drying box 1 from the feed port 11, and the bottom paper side of the self-adhesive label contacts the drying conveying wheel 2, so as to avoid the coding ink from contacting the drying conveying wheel 2, thereby causing the problem of unclear coding.

[0037] An anti-deflection ring 21 and an anti-deflection ring 22 are slidably connected to the annular outer wall of the drying conveying wheel 2, and an anti-deflection auxiliary plate 23 adapted to the feed port 11 and the discharge port 12 is fixedly connected to the anti-deflection ring 21 and the anti-deflection ring 22, and a guide groove 24 for guiding the self-adhesive label is provided on the anti-deflection ring 21 and the anti-deflection ring 22;

[0038] A circulating drying assembly 3 is arranged inside the drying conveying wheel 2. The circulating drying assembly 3 includes a heating seat 31 arranged inside the drying conveying wheel 2, and an annular electric heating net 32 ​​is installed inside the heating seat 31. A circulating fan 33 for blowing air into the heating seat 31 is installed on the outer wall of the drying box 1. The annular electric heating net 32 ​​is powered on to generate heat. The circulating fan 33 is started to inject the extracted air into the heating seat 31. After being heated into hot air by the annular electric heating net 32, the air is discharged into the drying conveying wheel 2 for heating treatment.

[0039] By heating the base paper of the self-adhesive label with the drying conveying wheel 2, the ink sprayed on the label paper is preliminarily preheated and dried without contact, which can effectively avoid the problem of ink being blown away and flowing due to wind, reducing the quality of the spraying. A spray printer 13 is movably installed on the top of the feed port 11, which is used to spray the self-adhesive label before it enters the drying box 1.

[0040] A motor 25 for driving the drying conveyor wheel 2 to rotate is bolted on the outer wall of the drying box 1. The motor 25 drives the drying conveyor wheel 2 to rotate, and the inkjet printer 13 conveys and inkjet codes the label paper of the self-adhesive label. A wave baffle made of elastic material is fixedly connected between one side of the feed port 11 and the discharge port 12 and the end of the corresponding anti-deflection auxiliary plate 23. The wave baffle can prevent part of the hot air from being discharged from between the corresponding anti-deflection auxiliary plate 23 and the feed port 11 or the discharge port 12, thereby reducing the effect of secondary drying of the self-adhesive label. The wave baffle made of elastic material can avoid interference with the movement of the anti-deflection ring.

[0041] An air inlet pipe 34 rotating with the drying conveying wheel 2 is installed between the heating seat 31 and the circulating fan 33. A plurality of air outlet holes 35 are equidistantly provided on the annular outer wall of the heating seat 31 to enable the hot air to be quickly discharged from the heating seat 31 to the inside of the drying conveying wheel 2. A serpentine heating cavity 26 is provided in the annular side wall of the drying conveying wheel 2. The serpentine heating cavity 26 can prolong the flow time of the hot air inside the side wall of the drying conveying wheel 2, thereby improving the heating effect on the drying conveying wheel 2.

[0042] One end of the serpentine heating chamber 26 penetrates the annular inner wall of the drying conveying wheel 2, and the other end penetrates the end outer wall of the drying conveying wheel 2. A heating zone is formed between the anti-deflection ring 1 21 and the anti-deflection ring 22, and an air injection zone is formed between the anti-deflection ring 1 21 and the drying box 1. The circulating fan 33 injects the extracted air into the heating seat 31, and after being heated into hot air by the annular electric heating net 32, it is discharged into the drying conveying wheel 2 from a plurality of air outlets 35, and then enters the air injection zone formed between the anti-deflection ring 1 21 and the drying box 1 from the serpentine heating chamber 26. The hot air is heated during the process of being discharged from the drying conveying wheel 2.

[0043] A filter box 36 filled with activated carbon particles is installed on the outer wall of the drying box 1, and a suction pipe 37 is connected between the filter box 36 and the inside of the drying box 1, and a connecting pipe 38 is connected between the filter box 36 and the circulating fan 33. A plurality of connecting holes 27 are opened on the anti-deflection ring 22, and an exhaust zone is formed between the anti-deflection ring 22 and the drying box 1. When the circulating fan 33 is started, air in the exhaust zone is extracted through the connecting pipe 38, the filter box 36 and the suction pipe 37;

[0044] Then, the air in the heating zone formed between the anti-deflection ring 1 21 and the anti-deflection ring 22 is extracted through the multiple connecting holes 27 on the anti-deflection ring 22, and the hot air is discharged after heating the drying conveying wheel 2, and the blown hot air can be sucked back into the heating seat 31, so that the circulation of hot air inside the drying box 1 is realized, thereby achieving the energy-saving effect of heat recovery and reuse, and the purification of the drying gas can be simultaneously completed through the filter box 36 filled with activated carbon particles inside.

[0045] One side of the anti-deflection ring 22 is rotatably connected to multiple air outlet pipes 28, and the anti-deflection ring 21 is rotatably connected to an air outlet pipe 29 that is slidably connected to the corresponding air outlet pipe 28. The free end of the air outlet pipe 29 is an open end. The hot air in the air injection area is gathered and enters the multiple air outlet pipes 29 and the air outlet pipe 28. A number of diversion holes are opened on the air outlet pipe 29 and the air outlet pipe 28, and then the air is diverted and sprayed to the heating area through the number of diversion holes, and contacts with the ink after preliminary drying. Combined with the heated drying conveying wheel 2, double-sided heating treatment is simultaneously performed to improve the drying efficiency and quality.

[0046] A small tooth ring 210 is fixedly connected to the air outlet pipe 1 29, and a large tooth ring 211 meshing with the small tooth ring 210 is fixedly connected to the drying conveying wheel 2. The large tooth ring 211 is driven to rotate by the rotation of the drying conveying wheel 2. The large tooth ring 211 drives a plurality of matching air outlet pipes 1 29 and air outlet pipes 2 28 to rotate through the meshing small tooth ring 210, so as to change the direction of the hot air ejected by the split flow in real time, thereby further expanding the secondary heating range.

[0047] A limiting groove is provided inside the air outlet pipe 1 29, and a limiting block is connected to the outer wall of the air outlet pipe 28 to realize the synchronous rotation of the air outlet pipe 1 29 and the air outlet pipe 2 28 to avoid blockage of the diversion hole. The relative sliding of the air outlet pipe 1 29 and the air outlet pipe 2 28 avoids interference with the movement of the anti-deflection ring position, and simultaneously realizes the synchronous adjustment of the heating zone space, so that the ejected hot air effectively acts on the label.

[0048] Example 2: Please refer to Figure 1-Figure 4 , Figure 7 and Fig. 9 As shown in the figure, the problem of lack of effective anti-bias structure and difficulty in accurately implementing inkjet coding can be solved by the following solutions:

[0049] In the present embodiment, a self-adhesive label coding drying structure comprises a drying box 1, and a feed port 11 and a discharge port 12 which are connected to each other at one side of the drying box 1. A drying conveying wheel 2 is rotatably installed inside the drying box 1, and an anti-deflection ring 1 21 and an anti-deflection ring 2 22 are slidably connected to the annular outer wall of the drying conveying wheel 2. The anti-deflection ring 1 21 and the anti-deflection ring 22 are located on both sides of the self-adhesive label, so that the self-adhesive label can be prevented from being conveyed in a deflected manner during the coding conveying process, thereby preventing the deviation of the coding position caused by the deviation of the self-adhesive label. The anti-deflection ring 1 21 and the anti-deflection ring 22 are both fixedly connected with an anti-deflection auxiliary plate 23 which is adapted to the feed port 11 and the discharge port 12;

[0050] The anti-deflection auxiliary plate 23 is not only used to facilitate the discharge of hot air inside the drying box 1 through the feed port 11 and the discharge port 12, but also can play an auxiliary anti-deflection effect before and after the self-adhesive label enters the drying box 1, thereby enabling the self-adhesive label to be quickly placed between the anti-deflection ring 1 21 and the anti-deflection ring 22 after entering the drying box 1. The anti-deflection ring 1 21 and the anti-deflection ring 22 are both provided with a guide groove 24 for guiding the self-adhesive label;

[0051] The end of the guide groove 24 extends to the end of the anti-deflection auxiliary plate 23. Through the set guide groove 24, one end of the self-adhesive label is prompted to extend from the feed port 11 into the drying box 1. Under the guidance of the guide grooves 24 on both sides, the end of the self-adhesive label can be quickly extended through the discharge port 12 without additional operation, thereby achieving rapid preliminary installation of the self-adhesive label.

[0052] The interior of the drying box 1 is fixedly connected with two groups of guide rods slidably connected to the anti-deflection ring 1 21 and the anti-deflection ring 22 between the feed port 11 and the discharge port 12. The provided guide rods are used to assist in adjusting the positions of the anti-deflection ring 1 21 and the anti-deflection ring 22 inside the drying box 1, and are rotatably connected with a bidirectional screw rod 14 threadedly connected to the anti-deflection ring 1 21 and the anti-deflection ring 22. One end of the bidirectional screw rod 14 passes through the outside of the drying box 1 and is fixedly connected with a first knob to facilitate the rotation of the bidirectional screw rod 14. Rotating the first torsion wheel drives the bidirectional screw rod 14 to rotate. The bidirectional screw rod 14 cooperates with the guide rod to push the anti-deflection ring 1 21 and the anti-deflection ring 22 to move relative to or apart from each other, thereby realizing anti-deflection transportation of self-adhesive labels of different sizes.

[0053] A sliding seat 15 is fixedly connected to the top of the discharge port 12, and an adjusting screw 16 is rotatably connected inside the sliding seat 15. One end of the adjusting screw 16 passes through the outside of the sliding seat 15 and is fixedly connected to a second knob to facilitate the rotation of the adjusting screw 16. A mounting seat 17 threadedly connected to the adjusting screw 16 is slidably installed inside the sliding seat 15. The inkjet printer 13 is bolted on the mounting seat 17. The adjusting screw 16 is driven to rotate by rotating the second torsion wheel. The adjusting screw 16 drives the inkjet printer 13 to adjust its position through the mounting seat 17, thereby realizing precise inkjet coding processing at different positions of the self-adhesive label.

[0054] A fixed platform 18 is fixedly connected to the annular wall of the drying box 1, and a fixed roller 19 is rotatably installed on the fixed platform 18. A movable pressure roller 110 is arranged on the top of the fixed roller 19. Before the self-adhesive label is inserted into the drying box 1, it is first passed between the movable pressure roller 110 and the fixed roller 19. Combined with the anti-deflection positioning of the anti-deflection ring 1 21 and the anti-deflection ring 22, and the movement of the self-adhesive label pulled by the drying conveying wheel 2, the self-adhesive label is stably conveyed in an anti-shaking manner during the coding process, thereby improving the coding quality;

[0055] The roller shafts at both ends of the movable pressing roller 110 are rotatably connected to movable blocks 111 that slide with the fixed platform 18, and a pressing spring 112 is fixedly connected between the top of the movable block 111 and the fixed platform 18. The movable block 111 and the pressing spring 112 are arranged to promote a greater squeezing force between the movable pressing roller 110 and the fixed roller 19, thereby combining the conveyance of the self-adhesive labels to achieve effective anti-sway conveyance of the self-adhesive labels.

[0056] Example 3: Please refer to Figure 1-Figure 9 As shown, the present invention also proposes a method for using the self-adhesive label coding and drying structure, comprising the following steps:

[0057] Step 1: Rotate the first torsion wheel to drive the bidirectional screw 14 to rotate, and the bidirectional screw 14 pushes the anti-deflection ring 1 21 and the anti-deflection ring 2 22 to move relative to or away from each other, so that one end of the self-adhesive label is extended into the drying box 1 from the feed port 11, and the bottom paper side of the self-adhesive label contacts the drying conveying wheel 2, and is guided by the guide groove 24 on the opposite side of the anti-deflection ring 1 21 and the anti-deflection ring 22, so that the end of the self-adhesive label is extended through the discharge port 12;

[0058] Step 2: The annular electric heating net 32 ​​is powered on for heating, and the circulating fan 33 is started. The air in the exhaust area formed between the anti-deflection ring 22 and the drying box 1 is extracted through the connecting pipe 38, the filter box 36 and the suction pipe 37, and then the air in the heating area formed between the anti-deflection ring 1 21 and the anti-deflection ring 22 is extracted through the multiple connecting holes 27 on the anti-deflection ring 22. The circulating fan 33 injects the extracted air into the heating seat 31, and after being heated into hot air by the annular electric heating net 32, it is discharged into the drying conveying wheel 2 from the multiple air outlets 35, and then enters the air injection area formed between the anti-deflection ring 1 21 and the drying box 1 from the serpentine heating cavity 26. The hot air is heated during being discharged from the drying conveying wheel 2;

[0059] Step 3: The drying conveying wheel 2 is driven to rotate by the motor 25, and the inkjet printer 13 conveys and inkjet codes the label paper of the self-adhesive label. The self-adhesive label base paper is heated by the drying conveying wheel 2, and the ink sprayed on the label paper is preliminarily heated and dried. The hot air in the air injection area is gathered and enters into a plurality of air outlet pipes 1 29 and air outlet pipes 2 28, and then is split and sprayed to the heating area through a plurality of diversion holes, and contacts with the preliminarily dried ink. The heated drying conveying wheel 2 is combined with the synchronous double-sided heating treatment to improve the drying efficiency and quality. The hot air in the heating area is then extracted again through a plurality of connecting holes 27, a connecting pipe 38, a filter box 36 and an air suction pipe 37 and injected into the heating seat 31 for rapid heating, and then circulated for heating and drying.

[0060] Step 4: The large toothed ring 211 is driven to rotate by the rotation of the drying conveying wheel 2, and the large toothed ring 211 drives a plurality of matching air outlet pipes 1 29 and 28 to rotate through the small toothed ring 210 meshing therewith, so as to change the direction of the hot air ejected by the diversion in real time, further expanding the secondary heating range, and the gas in the drying process is synchronously purified by the activated carbon particles in the filter box 36;

[0061] Step 5: Before the self-adhesive label is inserted into the drying box 1, it is first passed between the movable pressure roller 110 and the fixed rotating roller 19. Combined with the anti-deflection positioning of the anti-deflection ring 1 21 and the anti-deflection ring 2 22, the drying conveying wheel 2 pulls the self-adhesive label to move, so that the self-adhesive label is conveyed in an anti-shaking and stable manner during the coding process to improve the coding quality. By rotating the second torsion wheel to drive the adjustment screw 16 to rotate, the adjustment screw 16 drives the position of the inkjet printer 13 to be adjusted through the mounting seat 17 to achieve precise coding processing.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
