Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing, in particular to a temperature control component and a printing device. Background Art
[0002] Traditional offset printing is referred to as offset printing, and uses a PS plate (Pre-sensitized plate). The PS plate includes an oleophilic image part and a hydrophilic aluminum-based mesh plano-convex plate on the grained aluminum base. During printing, the fountain solution covers the entire plate surface, and because the oleophilic image part is hydrophobic, the fountain solution is only retained in the blank part of the hydrophilic non-image mesh. When applying ink, the blank part repels the oily ink due to water, and only the oleophilic image part is inked, and the image can be formed on the plate. The formed image is first transferred to the rubber blanket, and then transferred to the substrate to form a printed product. In the traditional offset printing process, the balance between ink and fountain solution will directly affect the printing quality and production efficiency, and adjusting the balance between the two requires quite skilled technology and experience. Eliminating the faults caused by the imbalance of ink and fountain solution is a thorny problem that traditional offset printing has long faced.
[0003] In the prior art, the use of waterless offset printing technology can avoid the balance problem between ink and fountain solution. Waterless offset printing is to use an ink-repelling silicone rubber coating on the offset printing plate as the ink-repelling non-image and text part of the printing plate. No fountain solution is required, and special ink is used for offset printing. Waterless offset printing uses the silicone rubber coating on the printing plate as the non-printing area, which can eliminate the water-ink balance control and also eliminate the use of water as an ink-repelling medium. In terms of printing quality, water-based printing can make the offset printing dots sharper and have better layering performance, and waterless offset printing can achieve higher line counts and contrast. The inking quality of waterless printing ink on the printing plate is affected not only by the special printing plate, but also by the viscosity of its special ink.
[0004] In the related art, when the temperature of the ink in the small ink-absorbing area of the printing plate in the printing machine is too high, the ink viscosity will be reduced, resulting in the corresponding fine graphics being smeared; when the temperature of the ink in the large ink-absorbing area of the printing plate is low, the ink viscosity will be increased, resulting in difficulty in ink transfer. The multiple ink-stirring rollers of the printing machine use cold water circulation to achieve temperature control of the ink, but the temperature of the ink delivered to the printing plate tends to be consistent. Therefore, the existing temperature control method cannot adapt to the ink temperature adjustment requirements of different areas of the printing plate, resulting in poor printing results.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0046] In the related art, when the temperature of the ink in the small ink-absorbing area of the printing plate in the printing machine is too high, the ink viscosity will be reduced, resulting in the corresponding fine graphics being smeared; when the temperature of the ink in the large ink-absorbing area of the printing plate is low, the ink viscosity will be increased, resulting in difficulty in ink transfer. The multiple ink-stirring rollers of the printing machine use cold water circulation to achieve temperature control of the ink, but the temperature of the ink delivered to the printing plate tends to be consistent. Therefore, the existing temperature control method cannot adapt to the ink temperature adjustment requirements of different areas of the printing plate, resulting in poor printing results.
[0047] In view of this, the first embodiment of the present invention provides a temperature control component 100, which is used in a printing component 200. Figures 1 to 3First, the specific configuration of the printing assembly 200 is introduced. The printing assembly 200 includes a printing plate cylinder 110. The printing plate cylinder 110 includes a silicone rubber layer 114, a resin layer 115, and an aluminum plate base 116 arranged in a stacked manner. The silicone rubber layer 114 can be located on the side of the resin layer 115 that is away from the aluminum plate base 116. It should be noted that the resin layer 115 can be a photosensitive resin layer 115 that plays an ink-receptive role. The silicone rubber layer 114 has an oleophobic property and does not stick to the ink 20.
[0048] Reference Figure 2 , the resin layer 115 has a side wall 1151 away from the aluminum substrate 116. The side wall 1151 has a first part 1152 and a second part 1153, the silicone rubber layer 114 can cover the first part 1152, and the second part 1153 can be arranged at intervals from the silicone rubber layer 114. It can be understood that the second part 1153 not covered with the silicone rubber layer 114 can absorb the ink 20. Specifically, the second part 1153 includes a first ink absorbing area 112 and a second ink absorbing area 113, and the first ink absorbing area 112 and the second ink absorbing area 113 are spaced apart and are both located on the outer side 111 of the printing plate cylinder 110. The surface area of the first ink absorbing area 112 is greater than the surface area of the second ink absorbing area 113, that is, the first ink absorbing area 112 is used for printing a larger area of graphics and text, and the second ink absorbing area 113 is used for printing a smaller area of graphics and text. It can be understood that the first ink absorbing area 112 and the second ink absorbing area 113 on the printing plate cylinder 110 are both curved surfaces.
[0049] Refer to the following Figures 1 to 6 The specific configuration of the temperature control component 100 of the embodiment of the present application is introduced. The temperature control component 100 includes a first air nozzle 210 and a second air nozzle 220. In some embodiments, the structures of the first air nozzle 210 and the second air nozzle 220 may be the same. In other embodiments, the structures of the first air nozzle 210 and the second air nozzle 220 may be different. Some embodiments of the present application are described by taking the first air nozzle 210 and the second air nozzle 220 having the same structure as an example.
[0050] Reference Figure 4, the first air nozzle 210 can be arranged toward the first ink absorption area 112 of the printing plate cylinder 110. The first air nozzle 210 can derive a first airflow and can guide the first airflow to the first ink absorption area 112. The second air nozzle 220 can be arranged toward the second ink absorption area 113 of the printing plate cylinder 110. The second air nozzle 220 can derive a second airflow and can guide the second airflow to the second ink absorption area 113. Among them, the temperature of the first airflow is higher than the temperature of the second airflow, that is, the first airflow can heat the ink 20 in the first ink absorption area 112, thereby reducing the viscosity of the ink 20 in this area, and the second airflow can cool the ink 20 in the second ink absorption area 113, thereby increasing the viscosity of the ink 20 in this area. It should be noted that the temperature of the first airflow and the second airflow is a comparison between the two, so the above-mentioned heating and cooling operations are also a comparison between the two, that is, the multiple airflows of this scheme can accurately control the viscosity of the ink 20 in different areas. Furthermore, the first air nozzle 210 may output a continuous or intermittent airflow of a specific temperature toward the first ink absorption area 112 , and the second air nozzle 220 may output a continuous or intermittent airflow of a specific temperature toward the second ink absorption area 113 .
[0051] In the technical solution of the utility model, the temperature control component 100 includes a first air nozzle 210 and a second air nozzle 220. In the prior art, the ink-stirring roller adopts a cold water circulation method, which causes the temperature of the ink delivered to the outside of the printing plate cylinder to be consistent, and cannot adapt to the ink temperature adjustment requirements of different areas of the printing plate, resulting in poor printing effect. The first air nozzle 210 of the temperature control component 100 of this solution can guide the first airflow to the first ink absorption area 112, and the second air nozzle 220 can guide the second airflow to the second ink absorption area 113. Because the temperature of the first airflow is higher than the temperature of the second airflow, this solution can make the temperature of the ink 20 in the first ink absorption area 112 higher than the temperature of the ink 20 in the second ink absorption area 113, that is, the viscosity of the ink 20 on the first ink absorption area 112 can be made lower than the viscosity of the ink 20 on the second ink absorption area 113. Because the surface area of the first ink absorption area 112 is larger than that of the second ink absorption area 113, that is, this solution can facilitate the transfer of ink 20 on the large-area first ink absorption area 112 and avoid the situation where the image and text are blocked in the small-area second ink absorption area 113, thereby achieving precise temperature control of the ink in different ink absorption areas of the printing plate cylinder 110, and effectively improving the printing effect and printing quality.
[0052] Reference Figure 2In some embodiments, the plate cylinder 110 includes a third ink absorption area 117 located on the outer side 111 thereof. The surface area of the third ink absorption area 117 is greater than the surface area of the first ink absorption area 112, and the third ink absorption area 117, the first ink absorption area 112 and the second ink absorption area 113 are arranged at intervals. The temperature control component 100 includes a third air nozzle, and the structure of the third air nozzle can be the same as that of the first air nozzle 210, or it can be different. Some embodiments of the present application are described by taking the third air nozzle and the first air nozzle 210 as an example of having the same structure. The third air nozzle can derive a third air flow and can guide the third air flow to the third ink absorption area 117. The temperature of the third air flow is higher than the temperature of the first air flow, that is, compared with the first ink absorption area 112, the viscosity of the ink 20 on the third ink absorption area 117 is less than the viscosity of the ink 20 in the first ink absorption area 112, that is, it can facilitate the transfer of ink 20 in the large area of the third ink absorption area 117. It should be noted that in some other embodiments, the printing plate cylinder 110 may further be provided with a fourth ink absorption zone and a fifth ink absorption zone, etc., and the specific number of the ink absorption zones may be determined according to actual conditions.
[0053] The specific setting of the first airflow derived from the first air nozzle 210 is described below. In some embodiments, the temperature of the first airflow is T1, and T1 satisfies: 30°≤T1≤60°. For example, T1 can be 30°, 35°, 42°, 47°, 55° or 60°, etc. The temperature of the first airflow is selected within the above temperature range, that is, the ink 20 in the first ink absorption area 112 can be effectively heated to reduce the viscosity of the ink 20, so as to facilitate the transfer of the ink 20 from the plate cylinder 110 to the silicone rubber cylinder 300, thereby ensuring the printing effect of the ink 20.
[0054] The specific setting of the second airflow derived by the second air nozzle 220 is described below. In some embodiments, the temperature of the second airflow is T2, and T2 satisfies: 10°≤T2≤20°. For example, T2 can be 10°, 12°, 15°, 16°, 18° or 20°, etc. The temperature of the second airflow is selected within the above temperature range, that is, the ink 20 in the second ink absorption area 113 can be effectively cooled, the viscosity of the ink 20 can be improved, and the situation of image and text smearing failure in the small area of the second ink absorption area 113 can be avoided, thereby ensuring the printing effect.
[0055] The relative arrangement positions of the first air nozzle 210 and the printing plate cylinder 110 are described below. In some embodiments, the first air nozzle 210 has a first end 211 facing the first ink absorption area 112. Figure 4The orientation in is used as a reference, that is, along the left-right direction, the first end 211 has a first distance D1 to the first ink absorption area 112, and D1 satisfies: 1cm≤D1≤5cm. Exemplarily, D1 can be 1cm, 2.5cm, 3cm, 4.5cm or 5cm. The first air nozzle 210 and the printing plate cylinder 110 of this solution adopt the above-mentioned configuration, which can not only ensure the heating effect of the first airflow on the ink in the first ink absorption area 112, but also avoid the situation of blowing the ink 20 away from the first ink absorption area 112, thereby ensuring the stability of the heating operation.
[0056] The relative arrangement position of the second air nozzle 220 and the printing plate cylinder 110 is described below. In some embodiments, the second air nozzle 220 has a second end 221 facing the second ink absorption area 113. Figure 4 The direction in is used as a reference, that is, along the left and right direction. There is a second distance D2 from the second end 221 to the second ink absorption area 113, and D2 satisfies: 1cm≤D2≤5cm. Exemplarily, D2 can be 1cm, 2.5cm, 3cm, 4.5cm or 5cm. It should be noted that D2 can be the same as D1 or different, depending on the actual situation. The second air nozzle 220 and the printing plate cylinder 110 of this scheme adopt the above-mentioned arrangement, which can not only ensure the cooling effect of the second airflow on the ink 20 in the second ink absorption area 113, but also avoid the situation of blowing the ink 20 away from the second ink absorption area 113, thereby ensuring the stability of the cooling operation.
[0057] Reference Figure 5 , the specific structure of the temperature control component 100 is introduced below. In some embodiments, the temperature control component 100 includes a plurality of first air nozzles 210 and a plurality of second air nozzles 220, and the number of the first air nozzles 210 may be the same as the number of the second air nozzles 220, or may be different. Some embodiments of the present application are described by taking the same number of the first air nozzles 210 and the second air nozzles 220 as an example. Specifically, the number of the first air nozzles 210 may be the same as the number of ink position keys on the printing component 200, and the number of the second air nozzles 220 may be the same as the number of ink position keys of the printing component 200.
[0058] The temperature control component 100 also includes a base 230, which can carry and fix each first air nozzle 210 and each second air nozzle 220. Along the axial direction parallel to the plate cylinder 110, each first air nozzle 210 can be arranged at intervals on the base 230. The interval between two adjacent first air nozzles 210 can be uniform or non-uniform. Along the axial direction parallel to the plate cylinder 110, each second air nozzle 220 can be arranged at intervals on the base 230, and the interval between two adjacent second air nozzles 220 can be uniform or non-uniform. The temperature control component 100 of this solution includes multiple first air nozzles 210 and multiple second air nozzles 220, that is, it can meet the temperature adjustment requirements of the ink 20 in different areas of the plate cylinder 110, realize precise control of the ink 20 in each area, and ensure the printing effect.
[0059] Reference Figures 4 to 6 In some embodiments, the temperature control assembly 100 includes a partition 240, which can be connected to the base 230, and the first air nozzle 210 and the second air nozzle 220 are located on opposite sides of the partition 240. Figure 4 As a reference, the first air nozzle 210 can be arranged on the upper side of the partition 240, and the second air nozzle 220 can be arranged on the lower side of the partition 240. The partition 240 of this solution can prevent the first airflow derived from the first air nozzle 210 and the second airflow derived from the second air nozzle 220 from interfering with each other, thereby ensuring the accuracy of the temperature adjustment operation of each airflow for each location of the ink 20.

It should be noted that the wind sources of the first wind nozzle 210 and the second wind nozzle 220 can be the same wind source or different wind sources.
[0061] Reference Figure 4In some embodiments, the printing assembly 200 includes a silicone rubber roller 300, the axis direction of the silicone rubber roller 300 is parallel to the axis direction of the plate cylinder 110. The printing assembly 200 also includes an impression roller 400, the axis direction of the impression roller 400 is parallel to the axis direction of the plate cylinder 110, and the impression roller 400 is located on the side of the silicone rubber roller 300 away from the plate cylinder 110. It can be understood that the substrate can be arranged between the impression roller 400 and the silicone rubber roller 300. The specific configuration of the printing assembly 200 can refer to the relevant known technology, and will not be repeated here.
[0062] In some embodiments, the air volume of the first airflow and the second airflow can be controlled by multiple solenoid valves controlled by PLC to control the flow of each air duct, thereby stably controlling the airflow of each part. In other embodiments, both the first airflow and the second airflow can be obtained by air conditioning, which has low operation cost and strong practicality.
[0063] The second embodiment of the utility model proposes a printing device 10, which includes the temperature control component 100 of the above embodiment and also includes a printing component 200. The temperature control component 100 can be separated from the printing component 200, or can be connected to the printing component 200, and its specific configuration can be determined according to actual conditions. This solution can facilitate the transfer of ink 20 on the large-area first ink absorption area 112, and avoid the situation where the image and text are blocked in the small-area second ink absorption area 113, and realize the precise temperature control of the ink in different ink absorption areas of the printing plate cylinder 110, effectively improving the printing effect and printing quality. It should be noted that the printing device 10 can be a waterless printing device, or a modified water-based printing device that can achieve a waterless printing effect.
