Description

Technical Field

[0001] This utility model belongs to the field of curing device technology, and in particular relates to a UV curing device for a multi-zone adjustable coating and molding machine. Background Technology

[0002] In the field of coating and molding processes, UV curing equipment is the core equipment for ensuring the quality of substrate coating, and it is widely used in the surface treatment of various substrates such as films, paper, and aluminum foil. However, existing UV curing equipment still has the following problems in practical applications: Traditional devices typically have fixed lamp positions, making it impossible to flexibly adjust the distance between the lamp and the substrate based on its thickness. This results in uneven energy distribution, making thin substrates susceptible to damage from excessive energy and thick substrates potentially under-cured. Furthermore, most devices employ an integrated lamp design, lacking zone control functionality. When dealing with scenarios involving differences in coating thickness across different areas of the substrate or localized pattern processing, only uniform intensity irradiation is possible, failing to achieve targeted curing and severely impacting the overall curing quality of the product. Therefore, we propose a multi-zone adjustable UV curing device for coating and molding machines. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned technical problems by providing a multi-zone adjustable UV curing device for coating and molding machines, which achieves the effect of flexibly adjusting the irradiation according to the thickness of the substrate and adjusting the irradiation according to the pattern differences.

[0004] In view of this, the present invention provides a multi-zone adjustable coating molding machine UV curing device, including a housing, an inspection door on the front side of the housing, an outlet channel on the right side of the housing, an inlet channel on the left side of the housing, an exhaust fan detachably mounted on the upper end of the housing, and an adjustment assembly. The adjustment assembly includes a self-locking motor disposed in the inner cavity of the housing, a lead screw detachably mounted on the drive end of the self-locking motor, an adjustment frame disposed in the middle of the inner cavity of the housing, and a lead screw sleeve fixedly mounted on the side of the adjustment frame near the lead screw. The housing has fixing strips fixedly installed on both sides of its inner cavity. The fixing strips have sliding grooves on their inner sides. The adjusting frame has a slider fixedly installed on the side near the sliding groove. The partitioning assembly includes a partition lamp frame located below the adjusting frame. Multiple infrared temperature sensors are fixedly installed on the lower right side of the partition lamp frame. A partition plate is provided at the lower end of the partition lamp frame. The bottom of the partition lamp frame is divided into a left lamp area, a middle lamp area, and a right lamp area by the partition plate. Multiple low-pressure mercury lamps are detachably installed at the bottom of the partition lamp frame.

[0005] Furthermore, the size of the lead screw is adapted to the size of the lead screw sleeve, and the lead screw and the lead screw sleeve are threaded together.

[0006] Furthermore, a UV-blocking glass is provided at the lower front end of the inspection door, and the UV-blocking glass is sealed to the inspection door.

[0007] Furthermore, the self-locking motor is located on the left side of the inner cavity of the housing, and the self-locking motor is detachably connected to the upper end of the inner cavity of the housing.

[0008] Furthermore, the size of the slider is adapted to the size of the groove, and the slider and the groove are slidably connected.

[0009] Furthermore, the upper end of the partition light assembly frame is detachably connected to the lower end of the adjustment frame, and the partition light assembly frame is located in the middle of the lower end of the adjustment frame.

[0010] Furthermore, the infrared temperature sensors are configured to be six in number, with each pair of infrared temperature sensors forming a group, corresponding to the two sides of the left lamp area, the middle lamp area, and the right lamp area, respectively.

Additionally, the lamp assembly can be divided into three independent zones (left, middle, and right) by a partition plate.

[0019] Reference Figures 1 to 4 A multi-zone adjustable coating molding machine UV curing device includes a housing 1, an inspection door 11 on the front side of the housing 1, an outlet channel 13 on the right side of the housing 1, an inlet channel 15 on the left side of the housing 1, an exhaust fan 14 detachably mounted on the upper end of the housing 1, and an adjustment assembly. The adjustment assembly includes a self-locking motor 21 disposed in the inner cavity of the housing 1, a lead screw 22 detachably mounted on the drive end of the self-locking motor 21, an adjustment frame 2 disposed in the middle of the inner cavity of the housing 1, and a lead screw sleeve 26 fixedly mounted on the side of the adjustment frame 2 near the lead screw 22. Fixing strips 23 are fixedly installed on both sides of the inner cavity of 1. A sliding groove 24 is opened on the inner side of the fixing strip 23. A slider 25 is fixedly installed on the side of the adjusting frame 2 near the sliding groove 24. The partitioning component includes a partition lamp frame 3 set below the adjusting frame 2. Multiple infrared temperature sensors 4 are fixedly installed on the lower right side of the partition lamp frame 3. A partition plate 6 is set at the lower end of the partition lamp frame 3. The bottom of the partition lamp frame 3 is divided into a left lamp area, a middle lamp area and a right lamp area by the partition plate 6. Multiple low-pressure mercury lamps 7 are detachably installed at the bottom of the partition lamp frame 3.

[0020] During the curing process, the substrate is first fed into the inner cavity of the housing 1 through the left inlet channel 15 via the coating machine's conveying system. Simultaneously, the exhaust fan 14 operates in real time to expel waste gas generated during curing, maintaining a clean and safe internal environment. When the adjustment component is in operation, the self-locking motor 21 receives a control signal and starts, driving the lead screw 22 to rotate. The lead screw 22 forms a threaded transmission with the lead screw sleeve 26 on the adjustment frame 2, causing the adjustment frame 2 to move smoothly along the slide groove 24 of the fixed strip 23 via the slider 25. This adjusts the distance between the zoned lamp assembly frame 3 and the substrate, ensuring a constant irradiation distance for substrates of different thicknesses. The bottom of the partition lamp assembly 3 is divided into three independent lamp zones: left, middle, and right, by the partition plate 6. The low-pressure mercury lamps 7 in each lamp zone can be started individually or in combination to perform targeted UV irradiation curing for different areas of the substrate with different coating thicknesses and pattern differences. This solves the problem of the one-size-fits-all curing of traditional devices, and is applicable to various substrates such as films, paper, and aluminum foil, as well as processing scenarios with uneven coating thickness and local patterns. At the same time, the infrared temperature sensor 4 monitors the temperature data of the corresponding lamp zone in real time, thereby avoiding the situation of substrate overheating and deformation. Finally, the cured substrate is sent out from the right exit channel 13.

[0021] It is worth noting that when the temperature of a certain area exceeds the preset threshold (default 80℃, which can be adjusted by the control system), the control system automatically reduces the power of the corresponding lamp area until the temperature drops below the threshold. If the temperature continues to rise to 100℃, the system triggers an audible and visual alarm and suspends the operation of the low-pressure mercury lamp 7 to prevent the substrate from overheating and being damaged. Each lamp area is independently equipped with a silicon controlled rectifier (SCR) voltage regulator, which is connected in series with the low-pressure mercury lamp 7. The output power of the voltage regulator is controlled by the analog signal output by the control system. The power adjustment range is 20%-100%, and the intensity of each lamp area can be precisely set according to the substrate coating thickness and curing requirements. For example, when the coating thickness at the edge of the substrate is 0.5μm, the power of the left / right lamp areas is set to 30%; when the coating thickness in the middle is 1.2μm, the power of the middle lamp area is set to 80%.

[0022] In the example of this application, the size of the lead screw 22 is adapted to the size of the lead screw sleeve 26, and the lead screw 22 and the lead screw sleeve 26 are threaded together.

[0023] As a preferred example of this utility model, when the self-locking motor 21 drives the lead screw 22 to rotate, the threaded transmission structure converts the rotational motion of the motor into the linear motion of the adjustment frame 2, thereby driving the adjustment frame 2 to move, realizing precise adjustment of the lamp group position and ensuring uniformity of irradiation energy.

[0024] In the example of this application, a UV-blocking glass 12 is provided at the lower front end of the access door 11, and the UV-blocking glass 12 is sealed to the access door 11.

[0025] As a preferred example of this utility model, during operation, the operator can observe the curing progress and status of the substrate inside the housing 1 through the glass. At the same time, the glass can effectively block the penetration and leakage of UV rays. The sealed design blocks the flow of dust between the inside and outside environment of the housing 1, avoids dust contamination of the substrate coating, and ensures the cleanliness of the curing environment.

[0026] In the example of this application, the self-locking motor 21 is disposed on the left side of the inner cavity of the housing 1, and the self-locking motor 21 is detachably connected to the upper end of the inner cavity of the housing 1.

[0027] As a preferred example of this utility model, the motor adopts a detachable connection, which facilitates later maintenance and replacement; when the adjustment frame 2 moves to the set position, the motor's self-locking function is activated, locking the rotation state of the lead screw 22 to prevent the adjustment frame 2 from shifting due to equipment vibration and other factors, thus maintaining the stability of the curing process.

[0028] In the example of this application, the size of the slider 25 is adapted to the size of the groove 24, and the slider 25 is slidably connected to the groove 24.

[0029] As a preferred example of this utility model, when the adjustment frame 2 moves, the guiding action of the slide groove 24 restricts the direction of movement of the adjustment frame 2, ensuring that the adjustment frame 2 always remains parallel to the substrate transmission path, and avoiding uneven illumination caused by lamp group offset.

[0030] In the example of this application, the upper end of the zone light assembly frame 3 is detachably connected to the lower end of the adjustment frame 2, and the zone light assembly frame 3 is located in the middle of the lower end of the adjustment frame 2.

[0031] As a preferred example of this utility model, the zoned lamp assembly frame 3 is detachably installed at the lower middle part of the adjustment frame 2, so that it covers the core area of ​​substrate transmission. The left, middle and right lamp zones can fully cover the surface of the substrate without any curing blind spots. The detachable design allows the lamp assembly frame to be disassembled separately for inspection and replacement of the low-pressure mercury lamp 7, reducing maintenance costs and downtime.

[0032] In the example of this application, there are six infrared temperature sensors 4, and each pair of infrared temperature sensors 4 forms a group, corresponding to the two sides of the left lamp area, the middle lamp area and the right lamp area respectively.

[0033] As a preferred example of this utility model, six infrared temperature sensors 4 correspond to the left, middle, and right lamp zones respectively (two sensors are configured for each lamp zone), which collect temperature data of each zone in real time and feed it back to the control system. When the temperature of a certain zone is too high or too low, the system can adjust the power or working time of the low-pressure mercury lamp 7 in the corresponding lamp zone to avoid coating damage or insufficient curing and ensure consistent curing quality throughout the entire area.

[0034] In the example of this application, light-blocking curtains 8 can be detachably installed on the outer side of both the outlet channel 13 and the inlet channel 15.

[0035] As a preferred example of this utility model, the light-blocking curtains 8 on the outside of the outlet channel 13 and the inlet channel 15 are in a naturally hanging state. The light-blocking curtains 8 can block UV rays from leaking out from the channel gaps, forming a double protection with the UV cut-off glass 12 to protect the operators from radiation damage. In addition, the light-blocking curtains 8 can also block external dust and debris from entering the housing 1, further maintaining the cleanliness of the internal curing environment.

[0036] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
