Description

Technical Field

[0001] This utility model relates to the field of digital printing technology, and more specifically, it relates to a rapid curing device for digital printing of labels. Background Technology

[0002] Digital printing is a new printing method that utilizes digital and computer technologies. It directly transfers digital image information onto the substrate, eliminating the need for the plate-making process in traditional printing.

[0003] In the digital printing process, curing is an indispensable part of the entire printing process; UV curing technology, UV-LED curing technology, and thermal curing technology are commonly used for curing.

[0004] However, in existing curing processes, the label material to be cured is easily blown around by the airflow inside the curing chamber, causing it to shake and the ink on the label material to slosh around, resulting in ink scratches and affecting the production quality of the label material. To address this, a rapid curing device for digital label printing is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rapid curing device for digital label printing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid curing device for digital label printing, comprising a transmission mechanism, a curing cover disposed above the transmission mechanism, lamp covers symmetrically arranged radially inside the curing cover, UV lamps disposed inside the lamp covers, and limiting components evenly arranged above the transmission mechanism, with an auxiliary plate disposed between two of the limiting components, the auxiliary plates being symmetrically distributed radially; the limiting components include a fixed plate, a telescopic cylinder disposed on the top of the fixed plate, a telescopic plate disposed at the telescopic end of the telescopic cylinder, fixed columns evenly arranged at the bottom of the telescopic plate, and a roller rotatably connected to the end of the fixed column away from the telescopic plate.

[0007] The present invention is further configured such that the bottom end of the curing cover is open and is located directly above the transmission mechanism.

[0008] The present invention is further configured such that: support plates are provided at both ends of the lampshade, the bottom of the support plates are connected to the inner wall of the curing cover, and slots are evenly provided on the side wall of the support plates; the lampshade is configured with a bottom opening, and connecting rods are symmetrically provided at both ends of the top of the lampshade, with the end of the connecting rod away from the lampshade being engaged in the corresponding slot.

[0009] The present invention is further configured such that: a fan is provided on the top of the curing cover, main louvers are symmetrically arranged at both ends of the fan in the axial direction, and secondary louvers are symmetrically arranged on both sides of the curing cover in the radial direction.

[0010] The present invention is further configured such that: the main body of the fixing plate has a C-shaped structure, the bottom of the fixing plate is connected to the top of the transmission mechanism, the telescopic end of the telescopic cylinder passes through the top of the fixing plate and is connected to the telescopic plate; in the initial state, the roller is suspended and does not contact the bottom of the inner wall of the fixing plate.

[0011] The present invention is further configured such that: the two sides of the auxiliary plate are inclined downward and are in contact with the top of the transmission mechanism, and the two ends of the auxiliary plate are connected to the corresponding side wall of the transmission mechanism.

[0012] The present invention is further configured such that: the auxiliary plate has symmetrical grooves at both ends, the fixing plate can be inserted into the corresponding grooves, and the top of the auxiliary plate is flush with the bottom of the inner wall of the fixing plate.

[0013] In summary, this application includes at least one of the following beneficial technical effects: The telescopic cylinder is activated, causing the telescopic plate to descend. Because the telescopic plate is connected to several fixed posts, and these fixed posts are also connected to several rollers, the rollers also descend until they contact the surface of the label material. At this time, the label material continues to be conveyed on the transmission mechanism, and the rollers roll along with the label material, achieving both the purpose of limiting the label material and without interfering with its conveying. This avoids the problem of the label material being blown around by the fan inside the curing box, causing it to shake and resulting in the ink on the label material sloshing around, thus improving the production quality of the label material and further increasing production efficiency.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] Please see Figures 1-7 The present invention provides the following technical solution:

[0027] Example 1, see Figures 1-7 A rapid curing device for digital label printing includes a transmission mechanism 1, a curing cover 2 above the transmission mechanism 1, lamp covers 3 symmetrically arranged radially inside the curing cover 2, UV lamps 4 inside the lamp covers 3, and limit components 5 evenly arranged above the transmission mechanism 1. An auxiliary plate 6 is arranged between the two limit components 5, and the auxiliary plate 6 is symmetrically distributed about the radial direction.

[0028] The limiting component 5 includes a fixed plate 51, a telescopic cylinder 52 disposed on the top of the fixed plate 51, a telescopic plate 53 disposed at the telescopic end of the telescopic cylinder 52, fixed posts 54 evenly disposed at the bottom of the telescopic plate 53, and a roller 55 rotatably connected to the end of the fixed post 54 away from the telescopic plate 53.

[0029] The function of the transmission mechanism 1 is to transport the label material. When the label material enters the curing cover 2, the UV lamp 4 inside the lamp cover 3 is activated to cure the ink on the surface of the label material. On the other hand, since the two sides of the auxiliary plate 6 are inclined downward and are in contact with the top of the transmission mechanism 1, the label material will be displaced upward through one side wall of the auxiliary plate 6 and transported to the top of the auxiliary plate 6. Since the fixing plate 51 is C-shaped, the label material will continue to be transported towards the bottom of the inner wall of the fixing plate 51.

[0030] During this process, the telescopic cylinder 52 is activated, and its output end extends, causing the telescopic plate 53 to descend. Since the telescopic plate 53 is connected to several fixed posts 54, and the several fixed posts 54 are also connected to several rollers 55, the rollers 55 also descend until they come into contact with the surface of the label material. It should be noted that the two sides of the label material are non-printed areas, so the rollers 55 will not directly contact the patterns on the label material.

[0031] At this time, the label material continues to be conveyed on the conveying mechanism 1, and the roller 55 rolls along with the label material, which not only achieves the purpose of limiting the label material, but also does not interfere with the conveying of the label material. Subsequently, the label material continues to be conveyed downward along the other side wall of the auxiliary plate 6 and leaves the auxiliary plate 6. This avoids the label material that needs to be cured being blown around by the fan inside the curing box, causing it to shake and the ink on the label material to shake back and forth, resulting in the ink scratching on the label material. This improves the production quality of the label material and further improves production efficiency.

[0032] It should be noted that the transmission mechanism 1 has all the necessary accessories and functions for transmission.

[0033] See Figures 1-7 Furthermore, the bottom of the curing cover 2 is open and located directly above the transmission mechanism 1.

[0034] The curing cover 2 has an open bottom and is closed on all other sides, which prevents the leakage of ultraviolet light emitted by the UV lamp 4 and reduces damage to the skin.

[0035] See Figures 1-7 Furthermore, the lampshade 3 is provided with support plates 11 at both ends, the bottom of the support plates 11 is connected to the inner wall of the curing cover 2, and slots 12 are evenly provided on the side wall of the support plates 11; the lampshade 3 is provided with an opening at the bottom end, and connecting rods 13 are symmetrically provided at both ends of the top of the lampshade 3, with the end of the connecting rod 13 away from the lampshade 3 being engaged in the corresponding slot 12.

[0036] The support plate 11 has multiple slots 12, which are evenly distributed along the height of the support plate 11. This allows the operator to adjust the height distance between the UV lamp 4 and the label material. Specifically, the operator holds the connecting rods 13 at both ends of the top of the lamp cover 3 and moves the connecting rods 13 along the slots 12 to achieve the optimal curing distance and avoid incomplete curing or label damage caused by poor distance.

[0037] See Figures 1-7 Furthermore, a fan 7 is provided on the top of the curing cover 2, and main louvers 8 are symmetrically arranged at both ends of the fan 7 in the axial direction, and secondary louvers 9 are symmetrically arranged on both sides of the curing cover 2 in the radial direction.

[0038] The combination of fan 7, main louver 8 and secondary louver 9 can effectively evaporate the gas inside curing chamber 2 and reduce the temperature inside curing chamber 2, preventing damage to the label material caused by high temperature.

[0039] See Figures 1-7 Furthermore, the main body of the fixing plate 51 is C-shaped, the bottom of the fixing plate 51 is connected to the top of the transmission mechanism 1, and the telescopic end of the telescopic cylinder 52 passes through the top of the fixing plate 51 and is connected to the telescopic plate 53; in the initial state, the roller 55 is suspended and does not contact the bottom of the inner wall of the fixing plate 51.

[0040] In the initial state, the roller 55 is suspended, which ensures that the label material can pass through normally even when the limit component 5 is in standby state, avoiding the situation where the label material cannot pass through the curing cover normally, and ensuring the normal operation of the curing process.

[0041] See Figures 1-7 Furthermore, the auxiliary plate 6 is inclined downward on both sides and is in contact with the top of the transmission mechanism 1. The two ends of the auxiliary plate 6 are connected to the corresponding side walls of the transmission mechanism 1.

[0042] The auxiliary plate 6 has symmetrical grooves 61 at both ends, and the fixing plate 51 can be inserted into the corresponding grooves 61. The top of the auxiliary plate 6 is flush with the bottom of the inner wall of the fixing plate 51.

[0043] Since the auxiliary plate 6 has symmetrical grooves 61 at both ends, the fixing plate 51 can be inserted into the corresponding grooves 61, thereby achieving the purpose of snapping the auxiliary plate 6 and the fixing plate 51 together.

[0044] Furthermore, since the top of the auxiliary plate 6 is flush with the bottom of the inner wall of the fixed plate 51, the label material can pass through the fixed plate 51 quickly, avoiding wrinkles in the label material during transmission and improving the production quality and efficiency of the label material.

[0045] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
