[0018] Example 1

[0019] like Figures 1 to 3 As shown, the present invention proposes a printing curing device, including a processing table 1, a curing hood 2, a drive mechanism, and a second gate 5; a conveyor belt mechanism 101 is provided on the processing table 1, which is existing technology, and the conveyor belt in the conveyor belt mechanism 101 is a Teflon conveyor belt used for ultraviolet irradiation curing of the printed parts; the curing hood 2 is detachably mounted on the top of the processing table 1 by bolts; the drive mechanism is located on the top of the curing hood 2, and its output end is slidably connected to the curing hood 2, and its output end extends into the interior of the curing hood 2. The UV curing lamp body 401 is driven by a drive mechanism to adjust along the height direction of the curing cavity inside the curing cover 2. Two sets of second baffles 5 are provided, and the top of each set of second baffles 5 is connected to the drive mechanism. The second baffles 5 are slidably connected to the curing cover 2. The curing cover 2 has a sliding channel that matches the second baffles 5. The second baffles 5 are driven by the drive mechanism to adjust along the height direction of the buffer cavity inside the curing cover 2. The second baffles 5 and the UV curing lamp body 401 move synchronously but in opposite directions.

[0020] Furthermore, the cross-section of the curing cover 2 is set as an inverted T-shape. The left and right sides of the inside of the curing cover 2 are set as buffer cavities, and the middle section of the inside of the curing cover 2 is set as the curing cavity. The height of the curing cavity is greater than the height of the buffer cavity, which facilitates the storage and adjustment of the UV curing lamp body 401 and prevents large-area leakage of light radiation from the UV curing lamp body 401. It should be noted that monitoring devices are set at appropriate positions at the feeding end of the buffer cavity and the feeding end of the curing cavity, which facilitates real-time monitoring of the arrival position of the printed parts conveyed on the conveyor belt mechanism 101 and transmits the monitoring information to the controller, which then drives the drive mechanism and other corresponding equipment to work.

[0021] Furthermore, the driving mechanism includes a hydraulic lifting column 3, a slide rod 302, and a first mounting plate 305; the hydraulic lifting column 3 is installed on the outer wall of the curing cover 2, and an adjustment frame 301 is installed at the top of the hydraulic lifting column 3; the slide rod 302 is slidably connected to the curing cover 2, the top of the slide rod 302 is connected to the adjustment frame 301, and the bottom of the slide rod 302 extends into the curing cavity inside the curing cover 2 and is connected to the UV curing lamp body 401; an electric push rod 4 is also provided between the slide rod 302 and the UV curing lamp body 401, which facilitates the UV curing lamp body 401 to continue to adjust its height through the electric push rod 4, thereby improving the curing efficiency of the printed parts; two sets of first mounting plates 305 are provided, and the two sets of first mounting plates 305 are respectively installed at the top of the corresponding second gate 5. A transmission component is provided between the two sets of first mounting plates 305 and the adjustment frame 301, and the first mounting plate 305 is adjusted in the opposite direction to the movement of the adjustment frame 301 through the transmission component;

[0022] Furthermore, the transmission assembly includes a first gear 303, a first toothed plate 304, and a second toothed plate 306; the first gear 303 is rotatably connected to a mounting base installed on the side wall of the curing cover 2; the first toothed plate 304 is installed on the side wall of the adjusting frame 301, and the first toothed plate 304 is meshed with the first gear 303; the second toothed plate 306 is installed on one side wall of the first mounting plate 305, and the second toothed plate 306 is meshed with the first gear 303.

[0023] In this embodiment, in the initial state, the driving mechanism drives the UV curing lamp body 401 to a suitable position at the upper end of the curing chamber, and at the same time drives the bottom of the two sets of second baffles 5 to get infinitely close to the top of the conveyor belt mechanism 101, so as to concentrate the ultraviolet rays emitted by the UV curing lamp body 401 between the two sets of second baffles 5 and the curing chamber, and prevent them from radiating outward to the staff.

[0024] The conveyor belt mechanism 101 initiates the movement of the printed part into the curing chamber 2. When the printed part reaches the buffer chamber at the inlet end and is about to enter the curing chamber, the hydraulic lifting column 3 initiates the downward movement of the adjusting frame 301. This, in turn, drives the UV curing lamp body 401 to move downward along the curing chamber to a suitable position via the slide rod 302. Simultaneously, the first toothed plate 304 on the adjusting frame 301 drives the first gear 303 to rotate, which in turn drives the first mounting plate 305 to slide upward via the meshing second toothed plate 306. This, in turn, drives the second stop 5 to slide upward along the curing chamber 2. When the appropriate height is reached, the channel between the buffer chamber and the curing chamber is opened. The printed parts can be continuously conveyed to the UV curing lamp body 401 in the curing chamber through the conveyor belt mechanism 101. The UV curing lamp body 401 cures the printed parts. The heat generated during curing is discharged through the exhaust fan at the top of the curing cover 2. By adjusting the electric push rod 4, the UV curing lamp body 401 can be moved closer to or further away from the printed parts to further improve the curing efficiency. The two sets of buffer chambers can block some of the ultraviolet rays to avoid large-area scattering and radiation pollution.

[0025] After the printed part is cured, it is conveyed by the conveyor belt mechanism 101 to the buffer cavity at the output end of the curing cover 2. At this time, the ultraviolet curing lamp body 401 and the two sets of second baffles 5 are driven by the drive mechanism to move to the initial position, continue to seal the curing cavity, thereby reducing the scattering of ultraviolet rays in the curing cavity, reducing radiation, and improving curing safety.

[0026] Example 2

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the printing curing device proposed in this utility model, compared with Embodiment 1, has protective mechanisms provided at both the input and output ends of the curing cover 2. The protective mechanisms include a first baffle 6, a second mounting plate 309, and a third toothed plate 308. The first baffle 6 is slidably connected to the input or output end of the curing cover 2. The second mounting plate 309 is installed on the top of the first baffle 6, and a fourth toothed plate 3010 is installed on the side wall of the second mounting plate 309. A second gear 307 is rotatably connected to the mounting seat on the side wall of the curing cover 2, and the fourth toothed plate 3010 is meshed with the second gear 307. The third toothed plate 308 is installed on the side wall of the first mounting plate 305 away from the second toothed plate 306, and is meshed with the second gear 307. A stabilizing seat 7 is installed on the side wall of the curing cover 2, and both the first mounting plate 305 and the second mounting plate 309 are slidably connected to the stabilizing seat 7, thereby improving the installation stability of the first mounting plate 305 and the second mounting plate 309 and avoiding interference with adjustments.

[0028] Furthermore, two sets of guide seats 201 are symmetrically installed at the input or output end of the curing cover 2. The first barrier 6 is slidably connected to the corresponding two sets of guide seats 201, which improves the stability and tightness of the connection between the first barrier 6 and the input or output end of the curing cover 2, and avoids radiation hazards caused by large-area ultraviolet scattering.

[0029] In this embodiment, when the conveyor belt mechanism 101 is about to transport the printed part from the buffer cavity at the input end of the curing cover 2 into the curing cavity, the drive mechanism adjusts so that the two sets of second baffles 5 slide upward along the curing cover 2 to a suitable height. At the same time, the UV curing lamp body 401 moves downward along the curing cavity to a suitable position. At this time, the first mounting plate 305 in the drive mechanism moves upward and drives the second gear 307 to rotate through the third toothed plate 308. This causes the fourth toothed plate 3010, which meshes with the second gear 307, to drive the second mounting plate 309 to move downward, thereby driving the first baffle 6 to slide downward along the guide seat 201 until the bottom of the first baffle 6 is infinitely close to the top of the conveyor belt mechanism 101. Then, the two sets of first baffles 6 block the inlet of the buffer cavity at the input end of the curing cover 2 and the outlet of the buffer cavity at the output end of the curing cover 2, further covering the ultraviolet rays of the UV curing lamp body 401, preventing the ultraviolet rays from spreading to the outside of the curing cover 2 and causing radiation hazards, and further improving curing safety.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
