Description

A high UV-resistant rubber ink curing device Technical Field

[0001] This utility model relates to the field of photocuring, and more specifically, to a device for curing rubber ink with high UV resistance. Background Technology

[0002] Rubber inks, also known as textured inks or hand-feel inks, possess a soft texture and rubbery elasticity, and are widely used in the coatings and inks industry. Photopolymerization technology is an advanced process that uses light of specific wavelengths (such as ultraviolet or visible light) to trigger a polymerization reaction in photosensitive materials, thereby achieving rapid curing. Its development history is closely linked to its application fields, reflecting the deep integration of materials science, optical engineering, and industrial needs.

[0003] A search revealed that Chinese patent CN219115045U discloses "A Photocuring Device." This utility model provides a photocuring device for curing ink on labels, comprising a frame, a first conveying device mounted on the frame, a photocuring device mounted on the frame and located above a first high-temperature resistant conveyor belt, a support rotatably connected to the frame at one end, a driving device for driving the support to rotate, and a second conveying device mounted on the support. The photocuring device includes a housing and two curing lamps mounted inside the housing, arranged side-by-side with their long axes perpendicular to the conveying direction of the first conveying device. The curing lamps are ultraviolet (UV) lamps. The driving device includes a cylinder rotatably connected to the frame, a connecting rod at one end of the cylinder's output end, and a connecting frame located below the support. The other end of the connecting rod is rotatably connected to the support. While this photocuring device is environmentally friendly, has high curing efficiency, and is highly adaptable, it still has the following drawbacks:

[0004] (1) The light is scattered and not concentrated, which directly reduces the curing efficiency of the ink by half; energy is seriously wasted, the curing is uneven, some places are exposed to too much light and may be scorched, while some places are not exposed to light and remain wet. The scattered ultraviolet rays may also damage the eyes of the operators, posing a safety hazard.

[0005] (2) Workers must be arranged to keep an eye on the high-temperature conveyor belt throughout the process. Items often shift, tilt or pile up during the conveying process. Because the position of the items is not fixed, some places are exposed to too much UV light and some places are not exposed enough. Such uneven curing will directly affect the product quality. It may cause the ink in some areas to not dry or to be over-cured and cracked. Moreover, manual adjustment is neither timely nor accurate, which seriously affects the production efficiency.

[0006] Therefore, a high UV-resistant rubber ink curing device is proposed. Summary of the Invention

[0007] The purpose of this invention is to address the current problem of scattered and unfocused light.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] The present invention is as follows: a high UV-resistant rubber ink curing device, comprising a conveying assembly, a curing chamber for curing rubber ink installed at the upper center of the conveying assembly, the conveying assembly being attached to the bottom left and right sides of the curing chamber, a reflector installed on the upper part of the inner wall of the curing chamber, a light assembly for UV curing rubber ink being fixedly installed on the upper inner side of the reflector, rectangular plates being installed on the front and rear sides of the lower part of the reflector, a wind-cooling assembly being installed on the upper part of the rear rectangular plate, and a baffle being installed on the lower part of the rectangular plate, with the baffle and the conveying assembly spaced at a certain distance.

[0010] The lighting assembly includes a lamp holder located in the lower middle part of the reflector, in which an ultraviolet lamp tube for curing rubber ink is embedded, and a quartz tube shell is fixedly installed on the outside of the ultraviolet lamp tube.

[0011] As a preferred technical solution of this utility model, the conveying assembly includes a support plate, a motor is fixedly installed on the outer right side of the support plate, a correction guide roller is fixedly installed on the upper inner side of the support plate, a high-temperature resistant conveyor belt is installed on the correction guide roller, and edge detection sensors are installed on both upper walls in the middle of the inner side of the support plate, with the edge detection sensors located above the high-temperature resistant conveyor belt.

[0012] As a preferred technical solution of this utility model, the air-cooling component includes an air outlet located on the upper part of the rear rectangular plate, an air duct fixedly installed on the back of the middle of the air outlet, the air duct passing through the curing chamber and the reflector, and a high-pressure centrifugal fan fixedly installed on the rear side of the outside of the curing chamber, and the air duct and the high-pressure centrifugal fan are fixedly connected.

[0013] As a preferred technical solution of this utility model, a baffle is connected to the lower part of the rectangular plate, and the baffle and the rectangular plate are connected by a hinge. A sensing device is fixedly installed on the front outer wall of the curing chamber, and the sensing device is located on the upper part of the baffle.

[0014] As a preferred technical solution of this utility model, glass windows are fixedly installed on both the left and right side walls of the curing chamber, and an infrared thermal imaging monitor is fixedly installed on the left side wall inside the curing chamber, with the infrared thermal imaging monitor located between the glass window and the ultraviolet lamp tube.

[0015] As a preferred technical solution of this utility model, an emergency stop button is installed on the right side of the outside of the curing chamber, and the emergency stop button is located at the lower part of the glass window.

[0016] As a preferred technical solution of this utility model, a self-locking universal wheel is fixedly installed on the lower part of the support plate. There are four sets of self-locking universal wheels, which are evenly distributed around the support plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By using a reflector, it can precisely focus the originally scattered light onto the ink surface, allowing the energy of the UV lamp to be used for curing, which is more energy-efficient than the unreflected state; secondly, this concentrated irradiation can increase the curing speed and greatly shorten the production cycle; the specially designed curved reflector can distribute the light evenly, ensuring that every corner of the ink receives the same irradiation intensity, completely solving the quality problem of "half dry and half sticky".

[0019] 2. After starting the motor power through the set conveyor components, the high-temperature resistant conveyor belt begins to run smoothly. The high-temperature resistant conveyor belt adopts an anti-slip design to ensure that the rubber products will not slip or shift during transportation. The edge detection sensor scans in real time. Once the product position is detected to be off, the correction guide roller will automatically make a fine adjustment to always maintain accurate alignment without manual intervention. This not only ensures that each product can pass through the curing area accurately, but also greatly reduces labor costs, making it particularly suitable for long-term continuous production.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0029] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] As shown in Figures 1-6, this embodiment proposes a high UV-resistant rubber ink curing device, including a conveying component 1. A curing chamber 2 for curing rubber ink is installed at the upper center of the conveying component 1. The left and right sides of the bottom of the curing chamber 2 are attached to the conveying component 1. A reflector 3 is installed on the upper part of the inner wall of the curing chamber 2. A light component 4 for UV curing rubber ink is fixedly installed on the upper inner side of the reflector 3. Rectangular plates 5 are installed on the front and rear sides of the lower part of the reflector 3. A wind-cooling component 6 is installed on the upper part of the rear rectangular plate 5. A baffle 7 is installed on the lower part of the rectangular plate 5. The baffle 7 and the conveying component 1 are spaced a certain distance apart.

[0033] The lighting assembly 4 includes a lamp holder 401 located in the lower middle part of the reflector 3. An ultraviolet lamp 402 for curing rubber ink is embedded in the lamp holder 401, and a quartz tube shell 403 is fixedly installed on the outside of the ultraviolet lamp 402. When in use, the motor 102 is turned on, and the conveyor assembly 1 and the ultraviolet lamp 402 begin to work. The rubber ink to be cured is spread evenly on the high-temperature resistant conveyor belt 104, which then conveys the rubber ink into the curing chamber 2. The ultraviolet lamp 402 emits strong light, which is concentrated on the rubber ink through the reflector 3, causing the rubber ink to dry and harden rapidly under ultraviolet irradiation.

[0034] As shown in Figures 3 and 4, in a preferred embodiment, based on the above method, the conveying assembly 1 further includes a support plate 101. A motor 102 is fixedly installed on the outer right side of the support plate 101. A guide roller 103 is fixedly installed on the upper inner side of the support plate 101. A high-temperature resistant conveyor belt 104 is installed on the guide roller 103. Edge detection sensors 105 are installed on both upper walls of the middle inner side of the support plate 101, located above the high-temperature resistant conveyor belt 104. When the motor 102 is powered on, the high-temperature resistant conveyor belt 104 starts to operate, spreading the rubber ink to be cured evenly on the high-temperature resistant conveyor belt 104. The high-temperature resistant conveyor belt 104 smoothly conveys the rubber product. The edge detection sensor 105 monitors the position in real time. When a deviation is detected, the guide roller 103 automatically adjusts its position to ensure that the product does not deviate.

[0035] As shown in Figures 1, 2, 3, 5, 6, and 7, in a preferred embodiment, based on the above method, the air-cooling component 6 further includes an air outlet 601 located on the upper part of the rear rectangular plate 5. An air duct 602 is fixedly installed on the back of the air outlet 601, passing through the curing chamber 2 and the reflector 3. A high-pressure centrifugal fan 603 is fixedly installed on the rear side of the curing chamber 2, and the air duct 602 and the high-pressure centrifugal fan 603 are fixedly connected. In use, the high-pressure centrifugal fan 603 delivers cold air to the curing chamber 2 through the air duct 602, and the cold air is evenly blown out from the air outlet 601, preventing damage to the rubber products caused by excessively high temperatures in the ultraviolet lamp tube 402.

[0036] As shown in Figures 1-6, in a preferred embodiment, based on the above method, a baffle 7 is further connected to the lower part of the rectangular plate 5, and the baffle 7 and the rectangular plate 5 are connected by a hinge. A sensing device 8 is fixedly installed on the front outer wall of the curing chamber 2, and the sensing device 8 is located above the baffle 7. When the rubber product on the high-temperature conveyor belt 104 approaches the baffle 7, the sensing device 8 will automatically detect the item, and the baffle 7 will open upward like an automatic door. After the product passes through, the baffle 7 will automatically close, effectively preventing leakage caused by the ultraviolet lamp 402.

[0037] As shown in Figures 1, 2, 6, and 7, in a preferred embodiment, based on the above method, glass windows 9 are fixedly installed on both the left and right side walls of the curing chamber 2, and an infrared thermal imaging monitor 10 is fixedly installed on the left side wall inside the curing chamber 2. The infrared thermal imaging monitor 10 is located between the glass window 9 and the ultraviolet lamp 402. When the equipment is working, the infrared thermal imaging monitor 10 will continuously scan the product temperature and observe the internal situation in real time through the glass window. If the temperature is too high, the high-pressure centrifugal fan 603 will be automatically turned on to cool down the rubber products inside the chamber to prevent the products from being damaged by baking.

[0038] As shown in Figure 1, in a preferred embodiment, based on the above method, an emergency stop button 11 is further installed on the right side of the exterior of the curing chamber 2. The emergency stop button 11 is located at the lower part of the glass window 9. This allows for instantaneous shutdown in case of danger, protecting personnel safety.

[0039] As shown in Figures 1, 3, and 4, in a preferred embodiment, based on the above method, a further step is to fix four sets of self-locking casters 12 to the lower part of the support plate 101, evenly distributed around the perimeter of the support plate 101. When the equipment needs to be moved, it can be easily moved by simply pushing it, making it convenient for use in different situations.

[0040] Specifically, in use, this high UV-resistant rubber ink curing device works as follows: The motor 102 is powered on, and the high-temperature conveyor belt 104 begins to operate. The rubber ink to be cured is spread evenly on the high-temperature conveyor belt 104, which smoothly transports the rubber product. The edge detection sensor 105 monitors the position in real time. When a deviation is detected, the guide roller 103 automatically adjusts its position. When the rubber product on the high-temperature conveyor belt 104 approaches the baffle 7, the sensor 8 automatically detects the item, and the baffle 7 opens upwards like an automatic door, allowing the product to pass through. Afterwards, the baffle 7 automatically closes, and the high-temperature resistant conveyor belt 104 sends the rubber ink into the curing chamber 2. The ultraviolet lamp 402 emits strong light, which is concentrated on the rubber ink through the reflector 3. Under the ultraviolet irradiation, the rubber ink dries and hardens quickly. At the same time, the infrared thermal imaging monitor 10 continuously scans the product temperature and observes the internal situation in real time through the glass window. If the temperature is too high, the high-pressure centrifugal fan 603 will be automatically turned on to cool down the rubber products in the chamber. The cold air is blown out evenly from the air outlet 601 to prevent the ultraviolet lamp 402 from being damaged due to excessive temperature.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
