The UV light curing machine of the above structure has the following shortcomings: (1) For workpieces that need to be shaded, black tape needs to be pasted on the workpiece to be cured for shade, which is inefficient when processed in batches, and the operation is troublesome, wasting manpower and material resources; (2) The irradiation range of the UV lamp is not easy to adjust, and the replacement and maintenance of the UV lamp are not convenient; (3) For the curing of special-shaped workpieces with relatively complex shapes, the curing cannot meet the curing requirements. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of UV light curing machine, which is convenient for adjusting the shading position and the irradiation power. It is more convenient for curing special-shaped or complex workpieces that need shading. Through the set liftable support plate and rotatable fixed seat, the workpiece to be cured can be evenly irradiated, and the gloss after molding is more uniform, which can effectively solve the problems in the background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A novel UV light curing machine comprises a sliding bracket, a first light source box, a second light source box, a first light shielding plate, a second light shielding plate, a liftable support plate, and a rotatable fixed seat. The first light source box, the second light source box, the first light shielding plate, and the second light shielding plate can be slid between the sliding brackets to adjust the position, thereby facilitating the adjustment of the light shielding position and the irradiation power.

[0008] Furthermore, an air inlet device and a rotating motor are provided on the top of the curing box from left to right in sequence, and the air inlet device is composed of a fan and an air inlet pipe. The air inlet pipe is fixedly connected to the input end of the fan, and a dust net is also provided on the upper end of the air inlet pipe. Protective covers are provided on the outside of the air inlet device and the rotating motor. The rotatable fixed seat is fixedly connected to the output end of the rotating motor. The rotatable fixed seat is used to clamp and fix the workpiece to be cured. When the workpiece to be cured is a circular or multi-faceted structure, the rotatable fixed seat can be driven by the rotating motor to uniformly irradiate the workpiece to be cured, so that the curing is more uniform.

[0009] Furthermore, a conveying motor is fixedly connected to one side of the support seat, an active conveying roller is fixedly connected to the output end of the conveying motor, a driven conveying roller is provided inside the support seat, the active conveying roller and the driven conveying roller are connected by a chain transmission, and a conveyor belt is fixedly connected to the top of the chain.

[0011] Furthermore, an exhaust port is provided on the rear side of the curing box, and an exhaust fan is provided on the exhaust port. A dust screen is fixedly connected to the outer side of the exhaust fan.

[0012] Furthermore, the first light shielding plate and the second light shielding plate are both configured as black acrylic plates with good light shielding performance, the bottom and top of the first light shielding plate and the second light shielding plate are both provided with second sliding grooves, and the sliding bracket is provided with sliding rails matching the first sliding grooves and the second sliding grooves.

[0013] Furthermore, the left and right sides of the curing box are both arranged as an opening structure, and the sliding bracket arranged at the upper part can also slide up and down on the curing box.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Compared with the traditional shading method of sticking black tape on the workpiece with curing, the method provided by the present invention for adjusting the shading position by sliding the first light source box, the second light source box, the first shading plate, and the second shading plate between the sliding brackets is simpler. It only needs to slide the relative position between the light source box and the shading plate to adjust the irradiation range of the UV lamp. The operation is also simpler and more convenient. At the same time, it can also play a better role in adjusting the irradiation power of the light source box.

[0016] 2. The first light source box and the second light source box are both connected with sealed doors on the outer side through hinges. The first light source box and the second light source box are both made of high-transmittance glass with good light transmittance on the inner side, which effectively ensures that the ultraviolet light in the first light source box and the second light source box can be well irradiated into the curing box. UV lamps with corresponding power and number are installed inside the first light source box and the second light source box according to actual needs. When different types of workpieces to be cured are replaced, causing changes in curing conditions, the first light source box and the second light source box can be removed from the movable bracket by moving the handle, and the number of UV lamps can be removed or increased by opening the sealed door to change the irradiation power. When the UV lamp inside the light source box fails or is damaged, it can be removed and replaced with a new one, which is convenient for replacing and repairing the UV lamp;

[0017] 3. In the present invention, an air inlet device is arranged on the top of the curing box, an exhaust port is arranged on the rear side of the curing box, an exhaust fan is arranged on the exhaust port, and a dustproof net is fixedly connected to the outer side of the exhaust fan. The air enters the curing box through the air inlet device and is then discharged through the exhaust port, which accelerates the air flow and heat exchange inside the curing box, facilitates the discharge of heat inside the curing box, and facilitates the heat dissipation inside the curing box. The waste gas inside the curing box can be discharged in time to prevent the curing quality from being affected.

[0018] 4. For workpieces that are not rectangular but cylindrical or truncated, the irradiation of common curing machines is not uniform. In the present invention, a rotatable fixed seat is used to clamp and fix the workpiece to be cured, and the area that does not need to be irradiated is shielded by a shading plate to improve the curing efficiency. The rotatable fixed seat is driven by a rotating motor to uniformly irradiate the workpiece to be cured, and the curing is more uniform. Compared with the irradiation curing of the traditional workpiece fixing method, the varnish attached to the surface of the workpiece after irradiation curing in the present invention is more uniform, and the molding effect is better;

[0019] 5. For workpieces with more complex shapes, the shading plate can be cut and designed into special shapes, and a light-transmitting hole of the same shape and size as the curing position can be cut on the shading plate. The workpiece is placed on a liftable support plate, and the liftable support plate is driven by a hydraulic cylinder to move up and down in the curing box in conjunction with the shading plate, which can effectively block light and cure workpieces with complex shapes.

The first light source box 6, the second light source box 13, the first light shielding plate 12, and the second light shielding plate 14 can be slid between the sliding bracket 5 to adjust the position, thereby facilitating the adjustment of the shading position and the irradiation power. It is more convenient for curing special-shaped or complex workpieces that require shading. The liftable support plate 18 and the rotatable fixed seat 21 can be used to evenly irradiate the workpiece to be cured, and the gloss after molding is more uniform.

[0031] Compared with common UV curing machines, the present invention configures a fixed light source box as a movable structure, and at the same time arranges a movable shading plate in the irradiation direction of the light source box. Compared with common fixed light source boxes, the present invention is more flexible, and it is more convenient to adjust the irradiation power parameters of the light source box and partially shield the workpiece. When the UV lamp inside the light source box fails or is damaged, it can be removed and replaced with a new one, which is convenient for replacing and repairing the UV lamp.

[0032] In this embodiment, the bottom of the sliding bracket 5 is fixedly connected to a support base 2, and the top of the support base 2 is fixedly connected to a curing box 1. The sliding bracket 5 is fixedly connected to the left and right ends of the curing box 1. The first light source box 6, the second light source box 13, the first light shielding plate 12, and the second light shielding plate 14 are all slidably connected to the sliding bracket 5. The first light shielding plate 12 and the second light shielding plate 14 are both arranged on the inner side of the first light source box 6 and the second light source box 13. By adjusting the position of the first light source box 6, the first light shielding plate 12 and the second light source box 13, the second light shielding plate 14, the irradiation range inside the curing box 1 can be conveniently adjusted, and the first light shielding plate 12 and the second light shielding plate 14 can better play a light shielding protection role for the position that does not need curing.

[0033] The method of adjusting the shading position by sliding the first light source box 6, the second light source box 13, the first shading plate 12, and the second shading plate 14 between the sliding bracket 5 is simpler. It only requires sliding the relative position between the light source box and the shading plate to adjust the irradiation range of the UV lamp. The operation is also simpler and more convenient. At the same time, it can also better adjust the irradiation power of the light source box.

[0034] The sliding bracket 5 can be set into two groups, one group is fixedly connected to the bottom of the curing box 1, and the other group is slidably connected to the upper position of the curing box 1 through bolts. When the first light source box 6 and the second light source box 13 need to be disassembled as a whole, the sliding bracket 5 set at the upper position of the curing box 1 can slide upward.

[0035] In the present embodiment, the first light source box 6 and the second light source box 13 are both configured as hollow boxes, and the first light source box 6 and the second light source box 13 are both provided with a first sliding groove 20 at the bottom and the top, and the first light source box 6 and the second light source box 13 are fixedly connected to one side with a movable handle 11, and the first light source box 6 and the second light source box 13 are both connected to a sealed door 19 on the outer side through a hinge, and the first light source box 6 and the second light source box 13 are both made of high-transmittance glass with good light transmittance on the inner side, which effectively ensures that the ultraviolet light in the first light source box 6 and the second light source box 13 can be well irradiated into the curing box 1, and it is convenient to replace and repair the UV lamp.

[0036] In order to ensure that the first light source box 6 and the second light source box 13 reduce light leakage to the outside during operation, the sliding blocks on the sliding bracket 5 are set into two groups, which respectively correspond to the sliding connection between the light source box and the shading plate. After installation, the shading plate is close to the light source box. At the same time, shielding cloths are set on both sides of the slide rails for installing the light source box to block the ultraviolet rays scattered from the front and back of the light source box.

[0037] In this embodiment, an air inlet device 10 and a rotating motor 9 are provided on the top of the curing box 1 from left to right in sequence. The air inlet device 10 is composed of a fan and an air inlet pipe. The air inlet pipe is fixedly connected to the input end of the fan. A dust net is also provided on the upper end of the air inlet pipe. A protective cover 7 is provided on the outside of the air inlet device 10 and the rotating motor 9. The rotatable fixed seat 21 is fixedly connected to the output end of the rotating motor 9. The rotatable fixed seat 21 is used to clamp and fix the workpiece to be cured. When the workpiece to be cured is a circular or multi-faceted structure, the rotatable fixed seat 21 can be driven by the rotating motor 9 to uniformly irradiate the workpiece to be cured, so that the curing is more uniform.

[0038] In this embodiment, a conveying motor 3 is fixedly connected to one side of the support seat 2, an active conveying roller 15 is fixedly connected to the output end of the conveying motor 3, a driven conveying roller 16 is provided inside the support seat 2, the active conveying roller 15 and the driven conveying roller 16 are connected by a chain transmission, and a conveyor belt 4 is fixedly connected to the top of the chain.

[0039] In this embodiment, the liftable support plate 18 is arranged at the bottom of the curing box 1, and a hydraulic cylinder 17 is fixedly connected to the bottom of the liftable support plate 18. The liftable support plate 18 is driven by the hydraulic cylinder 17 to rise and fall in the curing box 1 and used in conjunction with the shading plate, which can effectively play a role in shading and curing of workpieces with complex shapes.

[0040] In this embodiment, an exhaust port 22 is further provided on the rear side of the curing box 1, and an exhaust fan is provided on the exhaust port 22. A dustproof net is fixedly connected to the outer side of the exhaust fan. Air enters the interior of the curing box 1 through the air inlet device and is then discharged through the exhaust port 22, thereby accelerating the air flow and heat exchange inside the curing box 1 and facilitating the discharge of heat inside the curing box 1.

[0041] Among them, the air inlet device 10 is composed of a fan and an air inlet pipe. The air inlet pipe is fixedly connected to the input end of the fan. A dustproof net is also arranged on the upper end of the air inlet pipe. An exhaust fan is arranged on the exhaust port 22. A dustproof net is fixedly connected to the outer side of the exhaust fan. The dustproof net arranged at the air inlet and outlet can effectively prevent external dust from entering and contaminating the varnish surface.

[0042] An air inlet device 10 is arranged on the top of the curing box 1, and an exhaust port 22 is also arranged on the rear side of the curing box 1. An exhaust fan is arranged on the exhaust port 22, and a dustproof net is fixedly connected to the outer side of the exhaust fan. The air enters the curing box 1 through the air inlet device and is then discharged through the exhaust port 22, which accelerates the air flow and heat exchange inside the curing box 1, facilitates the discharge of heat inside the curing box 1, and facilitates the heat dissipation inside the curing box 1. The exhaust gas inside the curing box 1 can be discharged in time to prevent affecting the curing quality.

[0043] In this embodiment, the first light shielding plate 12 and the second light shielding plate 14 are both configured as black acrylic plates with good light shielding performance, and the bottom and top of the first light shielding plate 12 and the second light shielding plate 14 are both provided with second sliding grooves, and the sliding bracket 5 is provided with sliding rails matching the first sliding groove 20 and the second sliding groove.

[0044] In this embodiment, both left and right sides of the curing box 1 are configured as open structures, and the sliding bracket 5 disposed at the upper portion can also slide up and down on the curing box 1 .

[0045] When irradiating and curing common UV spray products, first adjust the position between the shading plate and the light source box to determine the irradiation range, use the conveyor belt 4 to transport the workpiece to the inside of the curing box 1, turn on the light source box, fan and exhaust fan, and transport the workpiece away via the conveyor belt 4 after irradiation and curing.

[0046] By adopting the above technical solution: the rapid curing of conventional curing products is effectively guaranteed, and parameters such as irradiation power required for different curing conditions are easily adjusted during the curing process.

[0047] Example 2

[0048] In this embodiment, the shape Figure 5 The truncated cone-shaped workpiece shown in the figure is cured. During processing, varnish is sprayed on the side of the truncated cone-shaped workpiece, and the side of the truncated cone-shaped workpiece needs to be irradiated and cured. Since the side of the truncated cone-shaped workpiece is not a plane, irradiation directly from the top or the side will result in uneven light reception, resulting in large differences in surface gloss after curing.

[0049] In the present invention, Figure 5 When the truncated cone-shaped workpiece shown in the figure is cured, the truncated cone-shaped workpiece is first clamped and fixed using the clamp arranged at the bottom of the rotatable fixed seat 21, and the light source box and the shading plate are adjusted to make the light source irradiate the workpiece more concentratedly, and the rotatable fixed seat 21 is driven by the driving motor 9 to evenly irradiate the workpiece to be cured, so that the curing is more uniform.

[0050] By adopting the above technical solution: a rotatable fixing seat 21 is used to clamp and fix the workpiece to be cured, and a shading plate is used to shade the area that does not need to be irradiated to improve the curing efficiency, and the rotatable fixing seat 21 is driven by a rotating motor 9 to evenly irradiate the workpiece to be cured, and the curing is more uniform. Compared with the traditional workpiece fixing method of irradiation curing, the varnish attached to the surface of the workpiece after irradiation curing obtained by the present invention is more uniform, and the molding effect is better.

[0051] Example 3

[0052] In this implementation, for example, Figure 6 The special-shaped workpiece shown in the figure is cured. The special-shaped workpiece consists of a smaller cube fixedly connected to the top of a larger rectangular block. In actual processing, the left and right sides of the cube and rectangular block need to be coated with varnish and cured, but the varnish materials used in the two curing positions are different, and the required ultraviolet irradiation curing intensities are different.

[0053] When curing the concave-shaped workpiece in this embodiment, first, two light-transmitting holes with the same shape and area as the left and right side surfaces of the cube and the rectangular parallelepiped are hollowed out from top to bottom on the first light-shielding plate 12 and the second light-shielding plate 14 on the left and right sides, and the workpiece is placed on the liftable support plate 18. The liftable support plate 18 is raised by the hydraulic cylinder 17 to the position where the upper light-transmitting hole can completely illuminate the left and right side surfaces of the cube, the power of the first light source box 6 and the second light source box 13 is adjusted, and the UV lamp is turned on for irradiation and curing. When the irradiation and curing of the left and right side surfaces of the cube are completed, the liftable support plate 18 is lowered by the hydraulic cylinder 17 to the position where the upper light-transmitting hole can completely illuminate the left and right side surfaces of the rectangular parallelepiped, the power of the first light source box 6 and the second light source box 13 is adjusted, and the UV lamp is turned on for irradiation and curing. Figure 5 Curing of the workpiece shown.

[0054] By adopting the above technical solution: for workpieces with more complex shapes, the shading plate can be cut and designed into a special shape, and a light-transmitting hole with the same shape and size as the curing position can be cut on the shading plate. The workpiece is placed on the liftable support plate 18, and the liftable support plate 19 is driven by the hydraulic cylinder 17 to rise and fall in the curing box 1 in conjunction with the use of the shading plate and the light source box, which can effectively play a role in shading and curing of workpieces with complex shapes.

[0055] Example 3

[0056] When the flexible material is photocured, the conveyor belt 4 can be removed, and the flexible material like plastic paper can be rolled up on the active conveyor roller 15. The active conveyor roller 15 is driven by the conveying motor 3 to rotate and transport the flexible material to the inside of the curing box 1 for curing, which is suitable for more products and improves the scope of use of the present invention.

[0057] It should be noted that the present invention is a new type of UV light curing machine. When in use, it should be ensured that the curing is in a closed dust-free environment. A dust cover 23 is arranged on the support seat 2, wherein a clamping block is arranged on the top of the support seat 2, and a clamping groove matching the clamping block is arranged at the bottom of the dust cover 23. After the curing box 1 is adjusted, the dust cover 23 is covered during the curing process to ensure a further dust-free environment during the curing process and improve the curing and varnish printing effects.

[0058] It should be noted that the present invention is a new type of UV light curing machine, in which the shapes of the first light shielding plate 12 and the second light shielding plate 14 are not fixed as rectangular parallelepipeds, and can be processed according to the actual needs of processing and curing workpieces. The number of the first light shielding plate 12 and the second light shielding plate 14 can be more than one, and multiple pieces can be set to form a light-transmitting area that matches the workpiece to be processed and cured.

[0059] Compared with the prior art, the present invention has the following beneficial effects:

[0060] Compared with the traditional shading method of sticking black tape on the workpiece to be cured, the method provided by the present invention for adjusting the shading position by sliding the first light source box 6, the second light source box 13, the first shading plate 12, and the second shading plate 14 between the sliding bracket 5 is simpler. It only needs to slide the relative position between the light source box and the shading plate to adjust the irradiation range of the UV lamp. The operation is also simpler and more convenient. At the same time, it can also play a better role in adjusting the irradiation power of the light source box.

[0061] The first light source box 6 and the second light source box 13 are both movably connected with a sealed door 19 on the outer side through a hinge. The first light source box 6 and the second light source box 13 are both made of high-transmittance glass with good light transmittance on the inner side, which effectively ensures that the ultraviolet light in the first light source box 6 and the second light source box 13 can be well irradiated into the curing box 1. UV lamps with corresponding power and number are installed inside the first light source box 6 and the second light source box 13 according to actual needs. When different types of workpieces to be cured are replaced to change the curing conditions, the first light source box 6 and the second light source box 13 can be removed from the movable bracket 5 by moving the handle 11, and the number of UV lamps can be removed or increased by opening the sealed door 19, thereby changing the irradiation power. When the UV lamp inside the light source box fails or is damaged, it can be removed and replaced with a new one, which is convenient for replacing and repairing the UV lamp.

[0062] In the present invention, an air inlet device 10 is arranged on the top of the curing box 1, and an exhaust port 22 is also arranged on the rear side of the curing box 1. An exhaust fan is arranged on the exhaust port 22, and a dustproof net is fixedly connected to the outer side of the exhaust fan. The air enters the curing box 1 through the air inlet device and is then discharged through the exhaust port 22, which accelerates the air flow and heat exchange inside the curing box 1, facilitates the discharge of heat inside the curing box 1, and facilitates the heat dissipation inside the curing box 1. The exhaust gas inside the curing box 1 can be discharged in time to prevent the curing quality from being affected.

[0063] For workpieces that are not rectangular but cylindrical or truncated, the irradiation of common curing machines is not uniform. In the present invention, a rotatable fixing seat 21 is used to clamp and fix the workpiece to be cured, and a shading plate is used to shield the area that does not need to be irradiated, thereby improving the curing efficiency. The rotatable fixing seat 21 is driven by the rotating motor 9 to uniformly irradiate the workpiece to be cured, and the curing is more uniform. Compared with the irradiation curing of the traditional workpiece fixing method, the varnish attached to the surface of the workpiece after irradiation curing obtained by the present invention is more uniform, and the molding effect is better.

[0064] For workpieces with more complex shapes, the shading plate can be cut and designed into a special shape, and a light-transmitting hole of the same shape and size as the curing position can be cut on the shading plate. The workpiece is placed on the liftable support plate 18, and the liftable support plate 18 is driven by the hydraulic cylinder 7 to move up and down in the curing box 1 in conjunction with the shading plate, which can effectively play a role in shading and curing of workpieces with complex shapes.

[0065] The above is a preferred embodiment of the present invention. The basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the present invention.
