Description

Technical Field

[0001] This utility model relates to the field of UV activation equipment technology, and in particular to a large-area, high-energy, and highly transparent silicone UV activation machine. Background Technology

[0002] UV activation: By irradiating with ultraviolet light, the chemical bonds on the surface of the plastic are broken, causing it to combine with oxygen in the air and produce peroxidation reactions, etc., generating carbon groups, KARUBOKISHIRU groups, hydroacid groups, etc. on the surface. As a result, the surface's organic properties are increased, making it easier to adhere to coatings, adhesives, and pressing agents with high organic properties. In the existing technology, there are many devices for UV modification of silicone. For example, Chinese Patent No. CN 219563875U discloses a new type of silicone UV modification machine, which includes a modification component, an air-cooling component, and a protective shell. One side of the protective shell is provided with an electrical control component for electrical connection with the modification component and the air-cooling component. Several interconnected modification cavities are arranged side by side inside the protective shell. The modification component and the air-cooling component are both located in the modification cavities. In use, the silicone is placed on the support crossbar of the chain conveyor belt. The drive motor drives the chain conveyor belt to run, so that the chain conveyor belt can carry the silicone through several modification cavities in sequence. During this process, the modification component modifies the silicone, thereby reducing the cumbersome operation during loading and unloading and increasing production efficiency. At the same time, the chain conveyor belt and sprocket drive can effectively prevent the conveyor belt from running off-track.

[0003] However, the aforementioned equipment is relatively long and can only activate products with a small area. Moreover, its activation permeability is not high, making it unsuitable for large-area products. Furthermore, its activation efficiency is low, making it difficult to meet the needs of large-scale production. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a large-area, high-energy, high-permeability silicone UV activation machine, comprising: a chassis, a conveying and transmission mechanism disposed on the chassis, and an activation mechanism disposed on the conveying and transmission mechanism. Two activation mechanisms are provided and connected. Each activation mechanism includes an air-entry activation outer box and two UV activation components symmetrically disposed within the activation outer box. Each UV activation component includes an air-collecting hood and a UV lamp array arranged along the length of the air-collecting hood opening.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention features two interconnected activation mechanisms that can simultaneously perform UV activation treatment on a large area of ​​the product, improving activation efficiency. Each activation mechanism is equipped with two UV lamp rows, each with UV lamps arranged along the length of the air collector hood opening. The UV lamps are U-shaped, resulting in a wider irradiation area and higher energy, thus improving activation penetration. Simultaneously, the top of the air collector hood is equipped with an axial fan and a filter plate, and the machine housing has an exhaust system that accelerates the removal of ozone generated after UV lamp irradiation, preventing ozone from affecting the working environment.

[0017] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] Please see Figure 1 and Figure 2 This embodiment provides a large-area, high-energy, high-transparency silicone UV activation machine, including: a housing 10, a conveying and transmission mechanism 20 disposed on the housing 10, and an activation mechanism 30 disposed on the conveying and transmission mechanism 20; wherein, there are two activation mechanisms 30, and the two activation mechanisms 30 are connected to form an activation tunnel. The product is fed into the activation tunnel for activation treatment through the conveying and transmission mechanism 20. Both the inlet and outlet ends of the activation tunnel are provided with light shields 40, and light shield curtains are provided at the ports of the light shields 40. A PLC control device 50 is installed on the top, and an alarm light with an alarm is also installed on the light shield 40. The PLC control device 50 controls the operation of the equipment. When the machine stops, the alarm light turns red. When a fault occurs, the alarm light turns red and the alarm sounds. Both activation mechanisms 30 include an activation outer box 31. The activation outer box 31 is fixed on the support frame of the conveyor transmission mechanism 20. Each activation outer box 31 has multiple air inlets on its top, and each air inlet is equipped with a filter 32. The air inlets allow the air inside the activation outer box 31 to flow.

[0019] In addition, please see Figure 3 , Figure 4 and Figure 5Two UV activation components 33 are symmetrically arranged inside the activation outer casing 31. Each UV activation component 33 includes an air collecting hood 330 and a UV lamp array 331 arranged along the length of the opening of the air collecting hood 330. The opening of the air collecting hood 330 is provided with a bracket 332 for fixing the UV lamp array 331. The bracket 332 is divided into left and right parts by a lamp holder 333. Each UV lamp array 331 has UV lamp tubes 334 arranged along the length of the opening of the air collecting hood 330 and fixed to the lamp holder 333. Each UV lamp tube 334 is U-shaped, and both ends of the UV lamp tube 334 are respectively fixed to the lamp holder 333. The frame 333 ensures the stability and uniform irradiation of the UV lamp tube 334. The design of the air collector hood 330 helps to focus the UV light and irradiate it evenly onto the product on the conveyor mechanism 20, improving activation efficiency. Multiple UV activation components 33 are set up, and multiple UV lamp rows 331 are set on the UV activation components 33, so that the irradiation area of ​​the UV lamp is wider and the energy is higher, improving activation penetration. Furthermore, the uniform movement of the conveyor mechanism 20 ensures that the product can receive UV light irradiation evenly and fully, further enhancing the activation effect.

[0020] To ensure airflow within the equipment, maintain uniform internal temperature, prevent overheating of the UV lamps 334, and extend their lifespan, several axial fans 335 are installed on the top of the air collector hood 330. A filter plate 336 with several ventilation holes is located on the upper side of the air collector hood 330. An air guide plate 337 connected to the filter plate 336 is located inside the air collector hood 330. The air guide plate 337 at one end of the axial fan 335 is inclined, with its upper surface facing the axial fan 335. An exhaust system is installed inside the housing 10, including a perforated plate 21 and a lower air collector hood 22 mounted on the conveyor drive mechanism 20, and an exhaust fan 11 inside the housing 10. Furthermore, an air outlet is located on the side of the housing 10, with one end connected to the exhaust fan 11 via a pipe, and the other end connected to external clean air via a pipe. The activation equipment is connected, and the axial flow fan 335 blows the cold air in the activation outer box 31 into the air collection hood 330. The air blown in by the axial flow fan 335 on the side is guided by the air guide plate 337 to the connection end between the bracket 332 and the UV lamp tube 334, so as to avoid the temperature of the connection end between the bracket 332 and the UV lamp tube 334 being too high, effectively protecting the UV lamp tube 334. The air blown in by the axial flow fan 335 on the top is guided by the air guide plate 337 to the periphery of the air collection hood 330, and the air flows into the activation tunnel through the ventilation holes of the air filter plate 336. As the exhaust fan 11 draws air from the activation tunnel, the odor generated during activation is removed. At the same time, the air in the activation tunnel is circulated, which can accelerate the discharge of ozone generated after UV lamp irradiation, avoid the impact of ozone on the working environment, and ensure that the internal temperature of the equipment is uniform, thus improving the activation efficiency and uniformity.

[0021] In summary, by setting up two wide and interconnected activation mechanisms 30, the overall width of the equipment is increased. The two activation mechanisms 30 can simultaneously perform UV activation treatment on a large area of ​​the product, improving the activation efficiency. Furthermore, each activation mechanism 30 is equipped with two UV lamp rows 331. Each UV lamp row 331 is equipped with UV lamp tubes 334 arranged along the length of the air collection hood 330 opening. The UV lamp tubes 334 are U-shaped, which makes the UV lamp irradiation area wider and the energy higher, thus improving the activation penetration.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
