Description

Technical Field

[0001] This utility model specifically relates to a multifunctional baffle for an auxiliary ultraviolet curing lamp used in inkjet printing. Background Technology

[0002] In the UV curing process of the printing industry, the UV curing lamp is the core component for curing inks and coatings. Currently, the baffles for UV curing lamps mostly adopt a semi-obstructed structure, and in some applications, the lamp body is even completely exposed, resulting in a very limited range of structural options.

[0003] On the one hand, partially obscured or exposed lamp bodies cannot completely block the leakage of ultraviolet light. Direct exposure to ultraviolet light can irritate the eyes and skin of operators, posing a significant safety hazard. On the other hand, unconstrained ultraviolet light will scatter in all directions, and most of the light cannot reach the surface of the printing substrate to be cured, resulting in low light source utilization. In order to achieve the preset curing effect, it is often necessary to increase the lamp power, which in turn leads to increased energy consumption. Utility Model Content

[0004] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a multifunctional baffle for an auxiliary ultraviolet curing lamp for inkjet printing.

[0005] A multifunctional baffle for an auxiliary ultraviolet curing lamp for inkjet printing includes a baffle body, which has multiple baffle bodies that are spliced ​​together to form a cavity. Each baffle body has a reflector on one side of the cavity.

[0006] In one embodiment, the reflector is a plurality of mirrors arranged in a rectangular array and the angle can be adjusted to promote the concentration of light on the curing area.

[0007] In one embodiment, the baffle body has a cavity, and the cavity is provided with a circulation pipe that allows coolant to circulate.

[0008] In one embodiment, the circulation pipeline has an inlet port and an outlet port, and the inlet port and outlet port are respectively located on the opposite outer side of a plurality of baffle bodies.

[0009] In one embodiment, a guide rail is provided on the upper side of the baffle body along its length direction to allow it to be installed and connected.

[0010] In one embodiment, the system further includes several sliders that can slide and engage with the guide rails. The sliders can be installed, removed, and fixed on an external mounting plate. The guide rails of the baffle bodies can slide onto the sliders one by one, and the baffle bodies can be spliced ​​together to enclose each other.

[0011] In one embodiment, the guide rail is a dovetail groove or an inverted T-shaped groove. The baffle body has at least two through holes that communicate with the guide rail at intervals on one side. The baffle body has a U-shaped frame on the opposite side to the reflector. Two limiting rods are threadedly inserted into the U-shaped frame at intervals. The two limiting rods are inserted into the through holes one by one and extend into the guide rail. The slider is movably disposed in the guide rail and located between the two limiting rods. The length of the slider is equal to the relative distance between the two limiting rods.

[0012] In one embodiment, the guide rail is a dovetail groove or an inverted T-shaped groove. The baffle body has at least two through holes that communicate with the guide rail at intervals on one side. The baffle body has a U-shaped frame on the opposite side to the reflector. Two limiting rods are elastically inserted into the U-shaped frame through an elastic component. The two limiting rods are elastically inserted into the through holes and extend into the guide rail. The slider is movably disposed in the guide rail and located between the two limiting rods. The length of the slider is equal to the relative distance between the two limiting rods.

[0013] In one embodiment, the perforations are distributed at intervals along the length of the baffle body.

[0014] In summary, the advantages of this utility model over the prior art are:

[0015] This invention utilizes multiple interconnected baffles to form a cavity, which encloses the UV curing lamp within the cavity, comprehensively blocking UV light leakage and preventing direct UV exposure to operators, significantly improving equipment safety. Simultaneously, a reflector is installed on the side of the baffle facing the cavity, reflecting UV light radiating towards the sidewall back onto the substrate to be cured inside the cavity, reducing light source loss and improving light utilization. This allows for lower lamp operating power while maintaining the same curing effect, achieving energy saving and consumption reduction. The modular design facilitates disassembly and maintenance and can be flexibly adapted to curing lamps of different sizes.

[0016] Furthermore, a cavity is set inside the baffle body and a circulation pipeline is arranged. The coolant can carry away the heat generated by the continuous irradiation of the ultraviolet lamp inside the cavity through the circulation of the pipeline, thereby reducing the ambient temperature inside the cavity and preventing high temperature from affecting the curing quality of temperature-sensitive inks and coatings. At the same time, it can extend the service life of the ultraviolet lamp body. The liquid inlet and outlet ports are located on the outside of the baffle body, which facilitates quick connection to an external cooling circulation system without affecting the splicing and installation of the baffle and the internal reflective structure.

[0017] Furthermore, a guide rail is provided on the upper side of the baffle body, which works with the slider on the external mounting plate to achieve sliding docking. During installation, the baffle can be assembled simply by sliding the guide rail along the slider. The assembly and disassembly operations are convenient, making it easy to remove, clean, and replace the baffle. Multiple baffles can be adjusted in relative position through the sliding cooperation of the guide rail and the slider to flexibly achieve enclosed splicing and adapt to different installation spacing and lamp body specifications.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 3 The present invention preferably provides a multifunctional baffle for an auxiliary ultraviolet curing lamp for inkjet printing, comprising a baffle body 1, wherein there are multiple baffle bodies 1, and the multiple baffle bodies 1 are spliced ​​together to form a cavity 2, and a reflector 3 is provided on one side of the baffle body 1 located inside the cavity 2.

[0023] Specifically, the cavity is formed by splicing together multiple baffles, which enclose the UV curing lamp inside the cavity, blocking UV light leakage from all directions and preventing direct UV light from shining on the operator, thus significantly improving the safety of equipment use. At the same time, a reflector is set on the side of the baffle facing the cavity, which can reflect the UV light radiating towards the side wall back to the printing substrate to be cured inside the cavity, reducing light source loss, improving light utilization, and reducing the lamp's operating power under the same curing effect, thus achieving energy saving and consumption reduction.

[0024] Furthermore, the reflector 3 has multiple mirrors, and the multiple reflectors 3 are arranged in a rectangular array and can be adjusted in angle to promote the concentration of light on the curing area.

[0025] Specifically, arranging multiple reflectors in a rectangular array can make the distribution of reflected light more uniform, ensure consistent light intensity in all areas of the cavity, improve the uniformity of curing on the surface of the printed substrate, and avoid problems such as insufficient or excessive curing in certain areas.

[0026] It is worth noting that an angle adjustment assembly is provided between the back of the reflector and the inner wall of the baffle body, with each reflector corresponding to a set of angle adjustment assemblies. The angle adjustment assembly includes a fixed base, a ball-head connecting rod, and a locking sleeve: the fixed base is fixedly installed on the inner wall of the baffle body, and a spherical groove (spherical socket) is opened inside the base, while an external thread section is provided on the outer wall of the base; one end of the ball-head connecting rod is a spherical end, and the other end is a connecting rod end; the spherical end is rotatably fitted into the spherical groove of the fixed base, and can achieve pitch and yaw multi-directional rotation within the groove; the connecting rod end is fixedly connected to the center of the back of the reflector.

[0027] The locking sleeve is an annular sleeve with internal threads, which is threaded onto the external thread section of the fixed base. The upper end of the locking sleeve is provided with a closing limiting edge. When the locking sleeve is tightened, the closing limiting edge presses down on the shoulder of the ball head, so that the inner wall of the spherical groove hugs the spherical end, thus locking the angle of the reflector.

[0028] As a simplified implementation, the reflectors in the same row can be fixed together on an adjustment shaft. The two ends of the shaft are mounted on the inside of the baffle through shaft seats with locking screws. Rotating the shaft can simultaneously adjust the pitch angle of the reflectors in that row, resulting in higher adjustment efficiency.

[0029] Furthermore, the baffle body 1 has a cavity 4, and the cavity 4 is provided with a circulation pipe 5 that allows the coolant to circulate.

[0030] Specifically, a cavity is set inside the baffle body and a circulation pipeline is arranged. The coolant can carry away the heat generated by the continuous irradiation of the ultraviolet lamp inside the cavity through the circulation of the pipeline, thereby reducing the ambient temperature inside the cavity and preventing high temperature from affecting the curing quality of temperature-sensitive inks and coatings. At the same time, it can extend the service life of the ultraviolet lamp body.

[0031] Furthermore, the circulation pipeline 5 has an inlet port 6 and an outlet port 7, and the inlet port 6 and the outlet port 7 are respectively located on the opposite outer side of a plurality of baffle bodies 1.

[0032] Specifically, the liquid inlet and outlet ports are located on the outside of the baffle body, which facilitates quick connection to an external cooling circulation system without affecting the splicing and installation of the baffle or its internal reflective structure.

[0033] Furthermore, a guide rail 8 is provided on the upper side of the baffle body 1 along its length direction to allow it to be installed and connected. Furthermore, it also includes several sliders 9 that can slide and engage with the guide rails 8. The sliders 9 can be installed, detached and fixed on the external mounting plate 10. The guide rails of the baffle bodies 1 can slide onto the sliders 9 one by one, and the baffle bodies 1 can be spliced ​​together to enclose each other.

[0034] Specifically, a guide rail is set on the upper side of the baffle body, which works with the slider on the external mounting plate to achieve sliding docking. During installation, the baffle can be assembled simply by sliding the guide rail along the slider. The assembly and disassembly are convenient, making it easy to remove, clean and replace the baffle. Multiple baffles can be adjusted in relative position by sliding the guide rail and slider to flexibly achieve enclosed splicing and adapt to different installation spacing and lamp body specifications.

[0035] In one embodiment, the guide rail 8 is a dovetail groove or an inverted T-shaped groove. The baffle body 1 has at least two through holes 11 connected to the guide rail 8 at intervals on one side. The baffle body 1 has a U-shaped frame 12 on the opposite side to the reflector 3. The U-shaped frame 12 is threadedly connected to two limiting rods 13 at intervals. The two limiting rods 13 are inserted into the through holes 11 one by one and extend into the guide rail 8. The slider 9 is movably disposed in the guide rail 8 and located between the two limiting rods 13. The length of the slider 9 is equal to the relative distance between the two limiting rods 13.

[0036] Specifically, the use of dovetail grooves or inverted T-grooves in the guide rail design prevents the slider from detaching from the guide rail, improving the stability of the sliding fit. By screwing the limiting rods on the U-shaped frame into the through holes of the baffle and extending into the guide rail, the slider is restricted between the two limiting rods, and the length of the slider is equal to the distance between the two limiting rods. This achieves axial positioning of the baffle relative to the mounting plate, preventing the baffle from sliding and shifting during operation. The positioning structure is simple, reliable, and has high adjustment accuracy.

[0037] In another embodiment, the guide rail 8 is a dovetail groove or an inverted T-shaped groove. The baffle body 1 has at least two through holes 11 at intervals on one side that communicate with the guide rail 8. The baffle body 1 has a U-shaped frame 12 on the opposite side to the reflector 3. Two limiting rods 13 are elastically inserted into the U-shaped frame 12 through an elastic component. The two limiting rods 13 are elastically inserted into the through holes 11 and extend into the guide rail 8. The slider 9 is movably disposed in the guide rail 8 and located between the two limiting rods 13. The length of the slider 9 is equal to the relative distance between the two limiting rods 13.

[0038] Specifically, the elastic component is a return spring, which is sleeved on the outside of the limit rod. The outer end of the limit rod is provided with a handle, and the rod is provided with a limit boss. One end of the return spring abuts against the outer wall of the U-shaped frame 12, and the other end abuts against the limit boss. Under normal conditions, the return spring is in a compressed state, pushing the limit rod to insert inward through the through hole and extend into the guide rail.

[0039] The limit rod is flexibly inserted and connected via an elastic component. Under normal conditions, the limit rod automatically extends into the guide rail under the action of elastic force to complete the limit locking. When the position of the baffle needs to be adjusted, simply pull the limit rod outward to compress the elastic component, which will cause the limit rod to exit the guide rail and unlock, eliminating the need for repeated twisting operations and greatly improving the efficiency of baffle position adjustment and disassembly. At the same time, the elastic component can provide continuous clamping force to buffer the vibration generated by the operation of the equipment, prevent the limit rod from loosening and shifting, and improve positioning reliability.

[0040] Furthermore, the perforations 11 are distributed at intervals along the length of the baffle body 1. Specifically, the multiple perforations along the length of the baffle body allow for adjustment of the insertion position of the limiting rod according to actual installation requirements, thereby changing the fixed position and splicing spacing of the baffle and further improving the adaptability and adjustment flexibility of the structure.
