Description

Technical Field

[0001] This utility model relates to the field of high-speed printing thermal materials technology, specifically a coating curing line for high-speed printing thermal materials. Background Technology

[0002] High-speed printing thermal material is a special paper or film material with a thermal coating on its surface. When the print head applies heat to it during the printing process, the thermal coating will undergo a rapid chemical reaction, thereby displaying information such as text, patterns or barcodes on the material surface. This material has the advantages of fast printing speed, no need for ink or toner, and ease of use. It is widely used in scenarios such as supermarket cashier receipts, logistics labels, and medical records.

[0003] Thermosensitive materials require the curing of the thermosensitive coating. The coating curing line can apply the thermosensitive coating to the thermosensitive material substrate, and then use heating, drying and other methods to evaporate the solvent in the coating and cross-link and fix the coating components to form a uniform and stable thermosensitive layer. The cured coating has good adhesion and chemical stability, which can ensure that the thermosensitive material can display colors normally and maintain its performance during printing.

[0004] After the coating curing line cures the thermosensitive material in the thermosetting chamber and removes it from the chamber, it cools the thermosensitive material with air cooling to ensure its structural stability and prepare it for the subsequent winding process. Although air cooling can cool the thermosensitive material, it is difficult to flatten it. During thermosetting, the thermosensitive material will generate residual stress and deformation due to thermal shrinkage and chemical shrinkage, resulting in local wrinkles and slight edge warping. Therefore, simple air cooling cannot solve the problem of local wrinkles and slight edge warping caused by the thermosensitive material, which will affect the quality of subsequent processing. Therefore, a coating curing line suitable for high-speed printing of thermosensitive materials is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a coating curing line suitable for high-speed printing of thermal materials. This line can not only cool the thermally cured material, but also smooth out local wrinkles and minor edge warping of the material while cooling, thereby ensuring the quality of subsequent processing and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A coating curing line for high-speed printing of thermal materials includes a processing table, a conveyor belt on top of the processing table, a thermosetting box above the conveyor belt, a cooling component on one side of the thermosetting box in the outlet direction, an edge smoothing component at the end of the cooling component near the thermosetting box, the cooling component including a cooling roller, a thermally conductive soft sleeve on the outer side of the cooling roller, a first gear fixedly connected to both ends of the cooling roller, a first support plate on the side of the first gear away from the cooling roller, the end of the cooling roller being rotatably connected to the first support plate, the bottom of the thermosetting box being fixedly connected to the top of the processing table, and the bottom of the first support plate being fixedly connected to the top edge of the processing table.

[0008] As a further optimization of this utility model, the thermally conductive sleeve is matched with the width specification of the conveyor belt, and the bottom of the thermally conductive sleeve is attached to the top of the conveyor belt.

[0009] As a further optimization of this utility model, the edge smoothing assembly includes a second support plate, the bottom of which is fixedly connected to the top edge of the processing table, and a second gear is rotatably connected to the inner side of the second support plate, the second gear meshing with the first gear.

[0010] As a further optimization of this utility model, the following features are provided: a first transmission shaft is fixedly connected to the center of the end of the second gear away from the second support plate; a first bevel gear is fixedly connected to the end of the first transmission shaft away from the second gear; and a second bevel gear is meshed with the first bevel gear.

[0011] As a further optimization of this utility model, a second transmission shaft is fixedly connected to the bottom center of the second bevel gear, and a transmission sleeve is fixedly connected to the bottom of the second transmission shaft. The transmission sleeve is rotatably connected to the top of the processing table.

[0012] As a further optimization of this utility model, the transmission sleeve is provided with several edge rods arranged at equal intervals and fixedly connected on its outer side, and the bottom of each edge rod is fixedly connected with a rubber pressure strip.

[0013] As a further optimization of this utility model, the bottom height of the rubber pressure strip is matched with the top height of the conveyor belt, and the length of the edge-smoothing rod is greater than the distance between the outer side of the transmission sleeve and the transmission belt and less than the shortest straight distance between the outer side of the transmission sleeve and the end of the cooling roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the thermosetting chamber heats the chemical substances in the coating to cause a cross-linking reaction, thereby curing the coating. The cooling component not only cools the thermosetting heat-sensitive material to ensure its structural stability but also flattens the local wrinkles caused by the thermosetting process, ensuring the quality of subsequent processing. The edge smoothing component smooths the minor edge warping of the heat-sensitive material before it reaches the cooling component from the outlet of the thermosetting chamber via the conveyor belt on the processing table. This not only improves the flattening effect of the cooling component on the heat-sensitive material but also prevents the edge warping from worsening after being flattened by the cooling component. Furthermore, the cooling component and the edge smoothing component do not require external drive; they are driven by friction with the conveyor belt, thus achieving energy saving.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0025] Please see Figure 1-6 This utility model provides a technical solution:

[0026] A coating curing line for high-speed printing of thermal materials includes a processing table 1, a conveyor belt 2 on the top of the processing table 1, a thermosetting box 3 above the conveyor belt 2, a cooling component 4 on the outlet side of the thermosetting box 3, an edge smoothing component 5 on the end of the cooling component 4 near the thermosetting box 3, the cooling component 4 including a cooling roller 41, a thermally conductive soft sleeve 42 on the outer side of the cooling roller 41, a first gear 43 fixedly connected to both ends of the cooling roller 41, a first support plate 44 on the side of the first gear 43 away from the cooling roller 41, the end of the cooling roller 41 rotatably connected to the first support plate 44, the bottom of the thermosetting box 3 fixedly connected to the top of the processing table 1, and the bottom of the first support plate 44 fixedly connected to the top edge of the processing table 1.

[0027] As a further implementation of this solution, the width of the thermally conductive sleeve 42 is matched with that of the conveyor belt 2, and the bottom of the thermally conductive sleeve 42 is attached to the top of the conveyor belt 2. The width of the thermally conductive sleeve 42 and the degree of attachment to the conveyor belt 2 can ensure the flattening range and effect of the thermally conductive sleeve 42 on the heat-sensitive material.

[0028] As a further implementation of this solution, the edge-smoothing component 5 includes a second support plate 51. The bottom of the second support plate 51 is fixedly connected to the top edge of the processing table 1. A second gear 52 is rotatably connected to the inner side of the second support plate 51. The second gear 52 meshes with a first gear 43. A first drive shaft 53 is fixedly connected to the center of the end of the second gear 52 away from the second support plate 51. A first bevel gear 54 is fixedly connected to the end of the first drive shaft 53 away from the second gear 52. A second bevel gear 55 meshes with the first bevel gear 54. A second drive shaft 56 is fixedly connected to the center of the bottom of the second bevel gear 55. A transmission sleeve 57 is fixedly connected to the bottom, and the transmission sleeve 57 is rotatably connected to the top of the processing table 1. Several edge smoothing rods 58 are arranged at equal intervals and fixedly connected to the outer side of the transmission sleeve 57. A rubber pressure strip 59 is fixedly connected to the bottom of the edge smoothing rod 58. The edge smoothing component 5 can smooth the slight edge warping of the heat-sensitive material before it is discharged from the outlet of the thermosetting box 3 through the conveyor belt 2 on the processing table 1 and reaches the cooling component 4. This not only improves the leveling effect of the cooling component 4 on the heat-sensitive material, but also prevents the edge warping from becoming more severe after being flattened by the cooling component 4.

[0029] As a further implementation of this solution, the bottom height of the rubber pressure strip 59 is matched with the top height of the conveyor belt 2, and the length of the edge smoothing rod 58 is greater than the distance between the outer side of the transmission sleeve 57 and the transmission belt and less than the shortest straight distance between the outer side of the transmission sleeve 57 and the end of the cooling roller 41. The height setting of the rubber pressure strip 59 can ensure the smoothing effect on the edge of the heat-sensitive material while ensuring its normal rotation, and prevent it from being obstructed by the cooling roller 41 when rotating.

[0030] Workflow: During curing, the coated heat-sensitive material is placed on one end of the conveyor belt 2 on the processing table 1. The conveyor belt 2 transports the heat-sensitive material towards the thermosetting chamber 3. After entering the thermosetting chamber 3, the heat in the chamber causes the chemical substances in the coating to undergo a cross-linking reaction, thereby curing the coating. After thermosetting, the heat-sensitive material continues to be transported by the conveyor belt 2. Its edges first pass through the edge smoothing assembly 5. Since the cooling roller 41 in the cooling assembly 4 is in contact with the top of the conveyor belt 2 through the outer heat-conducting soft sleeve 42, the conveyor belt 2 will drive the cooling roller 41 to rotate through friction during transport. The rotation of the cooling roller 41 will drive the first gear 43, which is rotatably connected to the first support plate 44 at its end, to rotate. The first gear 43 then drives the second gear 52, which is rotatably connected to the second support plate 51, to mesh and rotate. The second gear 52 drives the first bevel gear 54 to rotate through the first drive shaft 53. The first bevel gear 54 then synchronously drives the second bevel gear 51 through meshing. The bevel gear 55 rotates, and the second bevel gear 55 drives the transmission sleeve 57 and its edge smoothing rod 58 to rotate clockwise through the second transmission shaft 56. Finally, during the transport of the heat-sensitive material, the edge of the heat-sensitive material is continuously rotated and smoothed by the rubber pressure strip 59 to reduce or eliminate edge warping. After passing through the edge smoothing component 5, the heat-conducting soft sleeve 42 in the cooling component 4 passes through the cooling component 4. The heat-conducting soft sleeve 42 is made of graphene composite material, which has good thermal conductivity and flexibility, and can quickly conduct the heat of the coating to the interior of the cooling roller 41. The cooling roller 41 is designed with multiple cooling channels for circulating and transporting the cooling medium, which can quickly cool the heat absorbed by the heat-conducting soft sleeve 42, thereby cooling the heat-sensitive material. At the same time, the friction of the conveyor belt 2 rotates the cooling roller 41 and the heat-conducting soft sleeve 42 to roll and flatten the heat-sensitive material to ensure the subsequent processing quality of the heat-sensitive material.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
