Description

Technical Field

[0001] The invention relates to the technical field of UV curing, in particular to a precision electronic UV matte equipment. Background Art

[0002] At present, during the processing of matte UV decorative panels, a UV curing machine is needed to process the surface coating. The principle of the UV curing machine is to irradiate special glue with ultraviolet rays to cause the glue to polymerize and solidify.

[0003] In an existing UV curing machine, a reflector is usually provided on the outside of the UV lamp. The reflector is used to reflect the UV energy emitted by the UV lamp in a direction away from the product to be cured onto the product to be cured, so as to improve the utilization rate of the UV energy. However, the higher the temperature of the reflector, the lower its UV energy reflection ability. In the prior art, during the curing process, the fan blades are driven to rotate by a motor, and the wind generated thereby is blown to the outer surface of the reflector for air cooling and heat dissipation. In this heat dissipation structure, since only the surface of the reflector facing away from the UV lamp is blown by the wind, the heat dissipation effect of the reflector itself is not ideal, and the product to be cured usually requires another set of fans to cool it down to improve the curing efficiency. The provision of multiple sets of fans not only increases the production cost, but the cooling effect is usually not ideal.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a precision electronic UV matte equipment is proposed. Summary of the invention

[0009] Furthermore, a spray chamber is provided in the lower half of the chassis, and side panels are integrally fixed on both sides of the spray chamber, and an exhaust fan is provided at the bottom of the side panels.

[0010] Furthermore, the top bolt of the side panel is fixed with a fixing pin, and an opening and closing cylinder is rotatably installed inside the fixing pin through a pin shaft, the output end of the opening and closing cylinder is rotatably connected to a movable partition, and the movable partitions on both sides completely seal the middle opening of the bracket, and the root of the movable partition is rotatably connected to the adjacent side panel through a hinge.

[0011] Furthermore, a matte varnish storage tank is arranged on the outside of the right side of the spray chamber, and the top opening of the matte varnish storage tank is connected to a pump body through a hose. The top of the pump body is connected to two branch nozzles, and the branch nozzles are provided with several atomizing nozzles at equal intervals along the extension direction.

[0012] Furthermore, a synchronous drive assembly is fixed at the bottom end of the spray chamber, and the synchronous drive assembly includes a waste liquid pool, a vertical plate, a drive cylinder and a gear frame. The vertical plate is integrally fixed to the right end of the waste liquid pool, and the drive cylinder is fixedly installed on the outside of the vertical plate. The output end of the drive cylinder is fixedly connected to the gear frame, and the top end and the bottom end of the gear frame are evenly provided with plate teeth along the extension direction.

[0013] Furthermore, the synchronous drive assembly also includes a gear rod and a bearing seat. Two gear rods with staggered heights are rotatably installed in the middle of the vertical plate, and the two gear rods are respectively engaged with the plate teeth at the top end and the bottom end of the gear frame, and both gear rods are rotatably installed inside the bearing seat.

[0014] Furthermore, the synchronous drive assembly also includes a mounting plate and a clamping cylinder, the mounting plate is coaxially fixed to the end of the gear rod, and the clamping cylinder is fixed to the mounting plate by bolts inside.

[0015] The present invention provides a precision electronic UV matte equipment, which has the following beneficial effects:

[0016] 1. During the use of the present invention, the output end of the driving cylinder on the back of the vertical plate is fixedly connected with a tooth frame, and the top end and the bottom end of the tooth frame are evenly provided with plate teeth along the extension direction. The tooth frame meshes with two tooth rods with staggered heights through the plate teeth arranged at the top end and the bottom end of the tooth frame, so as to realize the synchronous rotation transmission of the two tooth rods. The two tooth rods are rotatably installed in the corresponding bearing seats, and the output end mounting plate can be used for clamping the material to be sprayed through the setting of the clamping cylinder. The material to be sprayed is staggered above the waste liquid pool. The input end of the pump body draws paint from the matte varnish storage tank, and the output end of the pump body is connected with two branch nozzles, each of which is provided with a continuous atomizing nozzle, so as to evenly spray the paint onto the surface of the material to be sprayed, and the dripping paint naturally falls into the waste liquid pool for subsequent uniform spraying. Collection and processing, when the spraying surface of the material to be sprayed faces the branch nozzle, the spraying operation of the two materials can be realized simultaneously, and at the same time, under the rotation transmission of the gear rod, the material to be sprayed can be turned 180 degrees, and the other side can be continuously sprayed. The automatic turning of the material to be sprayed can be realized without human intervention, which can effectively improve the spraying efficiency while avoiding the overflow of paint exhaust gas to pollute the production environment. In addition, in the subsequent curing operation, under the rotation transmission of the gear rod, the material to be sprayed can be turned 90 degrees, and the spraying surface can face the UV lamp for double-sided curing operation. Only one synchronous drive component is required to meet the production needs of the two processes of paint spraying and UV curing. At the same time, the double-station structural design can effectively improve the paint spraying and UV curing production efficiency of the material to be sprayed.

[0017] 2. During the use of the present invention, after the painting operation is completed, the exhaust fan at the bottom of the side panel is turned on to discharge the residual paint exhaust gas in the spray chamber. Thereafter, the movable partition is pulled by the opening and closing cylinder to rotate through the root hinge located at the adjacent side panel, so that the hole in the bracket originally closed by the movable partitions on both sides is opened. By using the movable partition to isolate the curing chamber in the upper half of the chassis from the spray chamber in the lower half, on the one hand, continuous paint spraying and UV curing operations can be carried out, and on the other hand, the paint exhaust gas generated by the paint spraying operation is prevented from passing into the curing chamber through the open hole in the bracket and adhering to the inner wall of the reflector to affect the reflection effect of UV energy, so that the two processes of paint spraying and UV curing that are independent of each other and carried out continuously in the prior art can be integrated in one chassis and carried out continuously, thereby improving the integration between processes and improving production efficiency.

[0018] 3. During the use of the present invention, when UV curing starts, one end of the control box is connected to the mains through a plug for power supply, and the other end is connected to the lamp holder through a wiring harness to realize synchronous power supply to the two UV lamps. The two UV lamps correspond to the two materials in the double-station of the synchronous drive component respectively, and UV curing operations can be performed synchronously. In order to solve the problem that most ultraviolet lamps for UV fixed operations in the prior art are fixed and cannot adjust the height according to materials of different thicknesses, thereby failing to maximize the efficiency of ultraviolet irradiation, the present application installs lifting cylinders at both ends of the inner side of the curing chamber to push the UV lamp to adjust the height up and down, so as to adjust the height to adapt to materials of different thicknesses and maximize the UV curing efficiency. In addition, during the lifting process of the lamp holder The T-pins at both ends thereof pull the bosses on the inner side of the reflector through the connecting arms, so that the reflector undergoes elastic deformation, thereby causing the reflector to change its curvature synchronously with the lifting and lowering of the lamp holder. Through the change in the curvature of the reflector that accompanies the lifting and lowering of the lamp holder, the light-emitting cover can always exert the optimal UV reflection efficiency, and the deformation of the reflector enables the airflow reflected by the bosses to be calibrated along with the lifting and lowering of the lamp holder, so that it can always be cooled by air in the corresponding direction of the material. The present application connects the lifting and lowering of the lamp holder with the change in the curvature of the reflector through a structural design in which T-pins are added at both ends of the lamp holder and the T-pins are connected to the bosses on the inner wall of the reflector through connecting arms, so that the reflector has a corresponding reflective effect and airflow guiding effect through the linked curvature change, and has stronger applicability.

[0019] 4. During the use of the present invention, in the continuous UV curing operation, the temperature of the reflector will gradually rise over time. However, the higher the temperature of the reflector, the lower its UV energy reflection ability. Therefore, it is necessary to activate the cooling fan to draw air from the outside of the chassis and send it into the curing chamber. The reflector of the present application has a parabolic structure with a notch downward. When the airflow output by the cooling fan passes through the upper surface of the reflector, it will naturally be diverted to both sides to cool the backlight surface of the reflector. At the same time, a groove is opened through the middle of the top of the reflector of the present application, and part of the airflow will pass through the groove to reach the air guide plate, which has a notch upward. The arc-shaped structure can diffuse the airflow vertically input through the grooves to the inner walls on both sides of the reflector, so as to cool the reflective surface of the reflector. In addition, the present application has symmetrical bosses at both ends of the reflector recess, so that the airflow flowing along the inner wall of the reflector can be directed toward two materials when output, so as to improve the UV curing efficiency of the material by air cooling. The present application only needs to set up one cooling fan, so as to simultaneously cool the outer backlight surface and the inner reflective surface of the reflector, thereby ensuring the reflective ability of the reflector to UV energy, and can also cool the material by air cooling, so as to further improve the UV curing efficiency of the material.

DETAILED DESCRIPTION

[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0030] See also Figures 1 to 8, including a chassis 1 and an air guide assembly 17, characterized in that a curing chamber 14 is opened in the upper part of the chassis 1, and a cooling fan 15 is fixed by bolts at the top of the middle of the curing chamber 14, and brackets 16 are integrally fixed at the bottom ends of both sides of the curing chamber 14, and the air guide assembly 17 is fixedly installed in the middle of the brackets 16 on both sides, and the air guide assembly 17 includes a reflector 1701, a boss 1702, a groove 1703, a connecting rod 1704, an air guide plate 1705 and a through hole 1706, and the reflector 1701 is a parabolic structure with a notch downward, and the reflector 170 1 is fixed to the brackets 16 on both sides by bolts, and the reflector 1701 is made of a deformable elastic metal material, bosses 1702 are symmetrically provided at both ends of the notch of the reflector 1701, and a groove 1703 is opened through the middle of the top of the reflector 1701, and a connecting rod 1704 is fixedly connected to the bottom opening of the groove 1703, and an air guide plate 1705 is fixedly connected to the end of the connecting rod 1704 away from the groove 1703, and the air guide plate 1705 is in an arc structure with the notch upward, and through holes 1706 are symmetrically opened on both sides of the middle of the air guide plate 1705;

[0031] The specific operation is as follows. During the continuous UV curing operation, the temperature of the reflector 1701 will gradually rise over time. However, the higher the temperature of the reflector, the lower its UV energy reflection ability. Therefore, it is necessary to activate the cooling fan 15 to draw air from the outside of the chassis 1 and send it into the curing chamber 14. The reflector 1701 of the present application is a parabolic structure with a notch downward. When the airflow output by the cooling fan 15 passes through the upper surface of the reflector 1701, it will naturally be diverted to both sides to cool the backlight surface of the reflector 1701. At the same time, a groove 1703 is opened through the middle of the top of the reflector 1701 of the present application. Part of the airflow will pass through the groove 1703 to reach the air guide plate 1705. The air guide plate 1705 is concave. The arc-shaped structure with the opening facing upward can diffuse the airflow vertically input through the strip groove 1703 toward the inner walls on both sides of the reflector 1701, and cool down the reflective surface of the reflector 1701. In addition, the present application symmetrically provides bosses 1702 at both ends of the notch of the reflector 1701, and can direct the airflow flowing along the inner wall of the reflector 1701 toward two materials when output, thereby improving the UV curing efficiency of the material by air cooling. The present application only needs to set up one cooling fan 15, and can simultaneously cool down the outer backlight surface and the inner reflective surface of the reflector 1701, thereby ensuring the reflective ability of the reflector 1701 to UV energy, and can also cool down the material by air cooling, so as to further improve the UV curing efficiency of the material.

[0032] See also Figure 6 to Figure 7, a lifting cylinder 18 is fixed with bolts at both ends of the inner side of the curing chamber 14, and the telescopic rod at the output end of the lifting cylinder 18 is slidably matched with the through hole 1706, and a lamp holder 19 is fixedly connected to the output end of the lifting cylinder 18, two UV lamps 20 are arranged side by side at the bottom of the lamp holder 19, and a wiring harness 21 extends from the top of the UV lamp 20, and the end of the wiring harness 21 is connected to the mains through a control box 22, and the control box 22 has a ballast and a starter built in, T-shaped pins 23 are symmetrically fixed on both sides of the lamp holder 19, and connecting arms 24 are rotatably connected to both sides of the T-shaped pin 23, and the end of the connecting arm 24 away from the T-shaped pin 23 is rotatably connected to the boss 1702;

[0033] The specific operation is as follows. When UV curing starts, one end of the control box 22 is connected to the mains power through a plug for power supply, and the other end is connected to the lamp holder 19 through a harness 21 to realize synchronous power supply to the two UV lamps 20. The two UV lamps 20 correspond to the two materials in the double-station of the synchronous drive component 13 respectively, and can perform UV curing operations synchronously. In order to solve the problem that most of the ultraviolet lamps in the prior art UV fixed operations are fixed and cannot adjust the height according to materials of different thicknesses, thereby failing to maximize the efficiency of ultraviolet irradiation, the present application installs lifting cylinders 18 at both ends of the inner side of the curing chamber 14, which can push the UV lamp 20 to adjust the height up and down to adapt to materials of different thicknesses for adjusting the height, thereby maximizing the UV curing efficiency. In addition, during the lifting process of the lamp holder 19, the T-pins 23 at both ends thereof pull the reflector 170 through the connecting arms 24. 1 The boss 1702 on the inner side causes the reflector 1701 to undergo elastic deformation, thereby causing the reflector 1701 to change its curvature synchronously with the rise and fall of the lamp holder 19. Through the change in curvature of the reflector 1701 accompanying the rise and fall of the lamp holder 19, the light-emitting cover can always exert the best UV reflection efficiency, and the deformation of the reflector 1701 enables the airflow reflected by the boss 1702 to be calibrated along with the rise and fall of the lamp holder 19, so that it always performs air cooling in the direction of the material. The present application connects the rise and fall of the lamp holder 19 with the change in curvature of the reflector 1701 through a structural design in which T-shaped pins 23 are installed at both ends of the lamp holder 19 and the T-shaped pins 23 are connected to the boss 1702 on the inner wall of the reflector 1701 through a connecting arm 24, so that the reflector 1701 has a corresponding reflective effect and airflow guiding function through the linked curvature change, and has stronger applicability;

[0034] See also Figure 4 A spray chamber 2 is provided in the lower half of the chassis 1, and side panels 3 are integrally fixed on both sides of the spray chamber 2, and an exhaust fan 4 is provided at the bottom of the side panel 3, a fixing pin 5 is fixed by bolts on the top of the side panel 3, and an opening and closing cylinder 6 is rotatably installed inside the fixing pin 5 through a pin shaft, and a movable partition 7 is rotatably connected to the output end of the opening and closing cylinder 6, and the movable partitions 7 on both sides completely seal the middle opening of the bracket 16, and the root of the movable partition 7 is rotatably connected to the adjacent side panel 3 through a hinge 8;

[0035] The specific operation is as follows. After the painting operation is completed, the exhaust fan 4 at the bottom of the side panel 3 is turned on to discharge the residual paint exhaust gas in the spray chamber 2. Thereafter, through the pulling of the opening and closing cylinder 6, the movable partition 7 is located at the adjacent side panel 3 through the root hinge 8 to rotate, so that the hole in the bracket 16 originally closed by the movable partitions 7 on both sides is opened. By using the movable partition 7 to isolate the curing chamber 14 in the upper part of the chassis 1 from the spray chamber 2 in the lower part, on the one hand, continuous paint spraying and UV curing operations can be carried out, and on the other hand, the paint exhaust gas generated by the paint spraying operation is prevented from passing through the open hole in the bracket 16 into the curing chamber 14 and adhering to the inner wall of the reflector 1701 to affect the reflection effect of UV energy, so that the two processes of paint spraying and UV curing that are independent of each other and carried out continuously in the prior art can be integrated in a chassis 1 and carried out continuously, thereby improving the integration between processes and improving production efficiency.

[0036] See also Figures 1 to 3 A matte varnish storage tank 9 is arranged on the outside of the right side of the spray chamber 2, and the top opening of the matte varnish storage tank 9 is connected to a pump body 10 through a hose, and the top of the pump body 10 is connected to two branch nozzles 11, and the branch nozzles 11 are arranged with several atomizing nozzles 12 at equal intervals along the extension direction, and a synchronous drive component 13 is fixed to the bottom end of the spray chamber 2, and the synchronous drive component 13 includes a waste liquid pool 1301, a vertical plate 1302, a driving cylinder 1303 and a gear frame 1304, the right end of the waste liquid pool 1301 is integrally fixed with a vertical plate 1302, and a driving cylinder 1303 is fixedly installed on the outside of the vertical plate 1302, and the output end of the driving cylinder 1303 is fixedly connected to the gear frame 130 4, and the top end and the bottom end of the gear frame 1304 are evenly provided with plate teeth along the extension direction, the synchronous drive assembly 13 also includes a gear rod 1305 and a bearing seat 1306, two gear rods 1305 staggered in height are rotatably installed in the middle of the vertical plate 1302, and the two gear rods 1305 are respectively meshed with the plate teeth at the top end and the bottom end of the gear frame 1304, and the two gear rods 1305 are rotatably installed inside the bearing seat 1306, the synchronous drive assembly 13 also includes a mounting plate 1307 and a clamping cylinder 1308, the mounting plate 1307 is coaxially fixed to the end of the gear rod 1305, and the clamping cylinder 1308 is fixed by bolts inside the mounting plate 1307;

[0037] The specific operation is as follows: the output end of the driving cylinder 1303 on the back of the vertical plate 1302 is fixedly connected to a tooth frame 1304, and the top and bottom of the tooth frame 1304 are evenly provided with plate teeth along the extension direction. The tooth frame 1304 meshes with two staggered tooth rods 1305 through the plate teeth arranged at the top and bottom of the inside, so as to realize the synchronous rotation transmission of the two tooth rods 1305.

The paint naturally falls into the waste liquid pool 1301 for subsequent unified collection and treatment. When the spraying surface of the material to be sprayed faces the branch nozzle 11, the spraying operation of the two materials can be realized simultaneously. At the same time, under the rotation transmission of the gear rod 1305, the material to be sprayed can be turned 180 degrees, and the other side can be continuously sprayed. The automatic turning of the material to be sprayed can be realized without human intervention, which can effectively improve the spraying efficiency while avoiding the overflow of paint exhaust gas to pollute the production environment. In addition, in the subsequent curing operation, under the rotation transmission of the gear rod 1305, the material to be sprayed can be turned 90 degrees, and the spraying surface is facing the UV lamp 20 for double-sided curing operation. Only one synchronous drive component 13 is required to meet the production requirements of the two processes of paint spraying and UV curing. At the same time, the double-station structural design can effectively improve the paint spraying and UV curing production efficiency of the material to be sprayed.

The tooth frame 1304 meshes with two staggered toothed rods 1305 through the plate teeth arranged at the top and bottom of the inside, so as to realize the synchronous rotation transmission of the two toothed rods 1305. The two toothed rods 1305 are rotatably installed in the corresponding bearing seats 1306, and the output end mounting plate 1307 can be used for clamping the material to be sprayed through the setting of the clamping cylinder 1308. The material to be sprayed is staggered above the waste liquid pool 1301, and the input end of the pump body 10 draws paint from the matte varnish storage tank 9. The output end of the pump body 10 is connected to two branch nozzles 11, and each branch nozzle 11 is provided with a continuous atomizing nozzle 12, which sprays the paint evenly onto the surface of the material to be sprayed. The dripping paint naturally falls into the waste liquid pool 1301 for subsequent unified collection and treatment. When the spraying surface of the material to be sprayed faces the branch nozzle 11, the spraying operation of the two materials can be realized simultaneously. At the same time, under the rotation transmission of the gear rod 1305, the material to be sprayed can be turned over 180 degrees, and the other side can be continuously sprayed. The automatic turning of the material to be sprayed can be realized without manual intervention, which can effectively improve the spraying efficiency while avoiding the overflow of paint exhaust gas to pollute the production environment. In addition, in the subsequent curing operation, under the rotation transmission of the gear rod 1305, the material to be sprayed The spraying material can be turned 90 degrees, and the spraying surface can face the UV lamp 20 for double-sided curing. Only one synchronous drive component 13 is required to meet the production requirements of the two processes of paint spraying and UV curing. At the same time, the double-station structural design can effectively improve the paint spraying and UV curing production efficiency of the material to be sprayed. After the painting operation is completed, the exhaust fan 4 at the bottom of the side panel 3 is turned on to discharge the residual paint exhaust gas in the spray chamber 2. Thereafter, through the pulling of the opening and closing cylinder 6, the movable partition 7 is located at the adjacent side panel 3 through the root hinge 8 and rotates, so that the hole in the bracket 16 originally closed by the movable partitions 7 on both sides is opened. By using the movable partition 7 to isolate the curing chamber 14 in the upper part of the chassis 1 from the spray chamber 2 in the lower part, on the one hand, it can be carried out The paint spraying and UV curing processes are performed continuously. On the other hand, the paint exhaust gas generated by the paint spraying process is prevented from entering the curing chamber 14 through the open hole in the bracket 16 and adhering to the inner wall of the reflector 1701 to affect the reflection effect of UV energy. The two processes of paint spraying and UV curing that are independent of each other and performed continuously in the prior art can be integrated in a chassis 1 and performed continuously, thereby improving the integration between processes and improving production efficiency. When UV curing starts, one end of the control box 22 is connected to the mains through a plug for power supply, and the other end is connected to the lamp holder 19 through a harness 21 to realize synchronous power supply to the two UV lamps 20. The two UV lamps 20 correspond to the two materials in the double stations of the synchronous drive component 13, respectively, and can perform UV curing operations synchronously.In order to solve the problem that most of the UV lamps used in the prior art for UV fixed operations are fixed and cannot be adjusted in height according to materials of different thicknesses, thereby failing to maximize the efficiency of UV irradiation, the present application installs lifting cylinders 18 at both ends of the inner side of the curing chamber 14, which can push the UV lamp 20 to adjust the height up and down to adapt to materials of different thicknesses and adjust the height to maximize the UV curing efficiency. In addition, during the lifting process of the lamp holder 19, the T-shaped pins 23 at both ends thereof pull the boss 1702 on the inner side of the reflector 1701 through the connecting arms 24, causing the reflector 1701 to undergo elastic deformation, thereby causing the reflector 1701 to move synchronously with the lifting of the lamp holder 19. The curvature of the reflector 1701 changes with the rise and fall of the lamp holder 19, so that the light hood can always exert the best UV reflection efficiency, and the deformation of the reflector 1701 enables the airflow reflected by the boss 1702 to be calibrated along with the rise and fall of the lamp holder 19, so that it always corresponds to the direction of the material for air cooling and cooling. The present application connects the rise and fall of the lamp holder 19 with the curvature change of the reflector 1701 through a structural design in which T-shaped pins 23 are installed at both ends of the lamp holder 19 and the T-shaped pins 23 are connected to the boss 1702 on the inner wall of the reflector 1701 through a connecting arm 24, so that the reflector 1701 has a suitable reflective effect and airflow guidance through the linkage curvature change. In the continuous UV curing operation, the temperature of the reflector 1701 will gradually rise with time. However, the higher the temperature of the reflector, the lower its UV energy reflection ability. Therefore, it is necessary to activate the cooling fan 15 to draw air from the outside of the chassis 1 and send it into the curing chamber 14. The reflector 1701 of the present application is a parabolic structure with a notch downward. When the airflow output by the cooling fan 15 passes through the upper surface of the reflector 1701, it will naturally be diverted to both sides to cool the backlight surface of the reflector 1701. At the same time, a groove 1703 is opened through the middle of the top of the reflector 1701 of the present application, and part of the airflow will pass through the groove 1703 to reach the air guide plate 1705. The air guide plate 1705 is an arc-shaped structure with an upward notch, which can diffuse the airflow vertically input through the groove 1703 to the inner walls on both sides of the reflector 1701, and cool the reflective surface of the reflector 1701. In addition, the present application symmetrically provides bosses 1702 at both ends of the notch of the reflector 1701, which can direct the airflow flowing along the inner wall of the reflector 1701 toward two materials when output, and improve the UV curing efficiency of the material by air cooling. The present application only needs to set up a cooling fan 15, and can simultaneously cool the outer backlight surface and the inner reflective surface of the reflector 1701, thereby ensuring the reflective ability of the reflector 1701 to UV energy, and can also cool the material by air cooling.
