Description

Technical Field

[0001] This utility model relates to the field of silicone roller processing technology, and in particular to a high-efficiency silicone roller hardening treatment device. Background Technology

[0002] A silicone roller is a cylindrical component coated with silicone adsorption material, using ceramic fiber or metal as the base material. It is widely used in industrial dehumidification, VOCs treatment and other fields. To improve the structural strength and high temperature resistance of the silicone roller, it needs to be hardened by heating to cross-link and cure the silicone, thereby enhancing the adhesion between the coating and the base material.

[0003] Existing silicone roller curing equipment is mostly a single-chamber heating furnace. Single-chamber equipment uses top or side single-point heating, resulting in a large temperature gradient inside the chamber (up to 15-20℃). The area of ​​the roller near the heating source is over-cured (silicone becomes brittle), while the area away from the heating source is under-cured (coating easily peels off), leading to large differences in the overall performance of the roller and thus affecting the uniformity of curing. Therefore, a high-efficiency silicone roller curing equipment is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency silicone roller hardening treatment device to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: a high-efficiency silicone roller curing equipment, including a frame, a control panel fixedly installed on the upper end of the frame, and a conveyor frame in the middle of the frame. A preheating box and a curing box are fixedly installed on the upper end of the frame above the conveyor frame. Both the preheating box and the curing box are equipped with heating structures and positioning structures. A silicone roller body is installed on the upper end of the conveyor frame. The heating structure includes heating pipes fixedly installed in the preheating box and the curing box. A filter plate is fixedly installed on the upper end of the preheating box, and two drive motors are symmetrically installed inside the filter plate. A fan is fixedly connected to the output end of each drive motor. Positioning rods are symmetrically installed inside the preheating box and the curing box, and guide plates are rotatably installed on the outer wall of each positioning rod.

[0006] As a preferred embodiment of the above technical solution, temperature sensors are fixedly installed on the inner walls of both the preheating box and the hardening treatment box, both fans are positioned above the heating tubes, and positioning plates are fixedly installed on the outer walls of both positioning rods.

[0007] As a preferred embodiment of the above technical solution, positioning seats are fixedly installed on both sides of the inner wall of the preheating box and the hardening treatment box. There are two positioning seats in total. The other positioning seat is fixedly installed at the lower end of the guide plate. An adjusting cylinder is provided between the two sets of positioning seats. The two ends of the adjusting cylinder are rotatably connected to the two positioning seats respectively.

[0008] As a preferred embodiment of the above technical solution, the positioning structure includes a mounting bracket fixedly installed in the frame, a positioning cylinder fixedly installed inside the mounting bracket, a limiting seat fixedly connected to one end of the positioning cylinder, and two limiting seats in total, with guide rack plates fixedly installed on the outer walls of both limiting seats.

[0009] As a preferred embodiment of the above technical solution, the outer walls of the two guide rack plates are meshed and connected to the outer wall of the main gear. The bottom of the main gear is rotatably mounted inside the mounting bracket. The outer walls of the two guide rack plates are slidably connected inside the limiting block. The bottoms of the two limiting seats are symmetrically equipped with two guide sliders, and the guide sliders are slidably connected to two guide rails.

[0010] As a preferred embodiment of the above technical solution, a limiting frame is fixedly installed on the upper end of both limiting seats, and a positioning clamp is fixedly installed on the outer wall of one end of the limiting frame, and an anti-slip pad is fixedly attached to the outer wall of the positioning clamp. A limiting plate is fixedly installed on the upper end of the mounting frame, and the two limiting frames are symmetrically slidably connected inside the limiting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model device is equipped with a preheating box and a hardening treatment box. The drive motor drives the fan to rotate, thereby blowing hot air from the heating tube onto the silicone roller. At the same time, the adjustment cylinders on the two positioning seats are driven to contract, thereby rotating the guide plate along the positioning rod as the axis. The fresh air is blown obliquely into the preheating zone through the guide plate and flows radially along the roller under the guidance of the guide plate, uniformly heating the roller. Through the coordinated design of zoned temperature control and uniform air supply, the hardening degree difference in each area of ​​the roller is ≤5%, the qualified product rate is steadily improved, the coating peeling problem caused by insufficient local hardening is avoided, and the uniformity of hardening treatment is improved.

[0013] 2. The device of this utility model is equipped with a positioning structure. The positioning cylinder in the drive mounting frame drives the positioning frame on the limiting seat to move. When the limiting seat moves, it uses the guide rack plate to mesh with the main gear to rotate. The main gear drives another guide rack plate to mesh and move synchronously, thereby driving the limiting seat on the other limiting seat to move relative to it. The two limiting frames drive the positioning clamp plate to slide relative to each other along the inner groove of the limiting plate to position and clamp the silicone wheel, which is beneficial for limiting and fixing the silicone wheel.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4As shown in the figure, this embodiment provides a high-efficiency silicone roller curing device, including a frame 1. A control panel 2 is fixedly installed on the upper end of the frame 1, and a conveyor frame 5 is provided in the middle of the frame 1. A preheating box 3 and a curing box 4 are fixedly installed on the upper end of the frame 1 above the conveyor frame 5. A heating structure 8 and a positioning structure 7 are provided inside the preheating box 3 and the curing box 4, respectively. A silicone roller body 6 is provided on the upper end of the conveyor frame 5. The heating structure 8 includes heating tubes 82 fixedly installed in the preheating box 3 and the curing box 4. A filter plate 81 is fixedly installed on the upper end of the preheating box 3, and two drive motors 84 are symmetrically installed inside the filter plate 81. A fan 85 is fixedly connected to the output end of each drive motor 84. Positioning rods 89 are symmetrically installed inside the preheating box 3 and the curing box 4, and guide plates 88 are rotatably installed on the outer wall of each positioning rod 89.

[0023] like Figures 2 to 4 As shown, temperature sensors 83 are fixedly installed on the inner walls of both the preheating box 3 and the hardening treatment box 4. Two fans 85 are both installed above the heating tube 82. Positioning plates 881 are fixedly installed on the outer walls of both positioning rods 89. Positioning seats 86 are fixedly installed on both sides of the inner walls of both the preheating box 3 and the hardening treatment box 4. There are two positioning seats 86 in total. The other positioning seat 86 is fixedly installed at the lower end of the guide plate 88. An adjusting cylinder 87 is provided between the two sets of positioning seats 86. The two ends of the adjusting cylinder 87 are rotatably connected to the two positioning seats 86 respectively.

[0024] By setting a temperature sensor 83 and electrically connecting it to the control panel 2, and simultaneously driving the motor 84 and the heating tube 82 to be electrically connected to the uniform controller, this is an existing mature technology and has not been described in detail in this application. At the same time, the adjusting cylinder 87 on the driving positioning seat 86 drives the guide plate 88 to rotate, thereby guiding the hot air blown out by the fan 85 to be evenly blown onto the silicone wheel.

[0025] like Figure 3As shown, the positioning structure 7 includes a mounting bracket 71 fixedly installed inside the frame 1. A positioning cylinder 72 is fixedly installed inside the mounting bracket 71. One end of the positioning cylinder 72 is fixedly connected to a limiting seat 73. There are two limiting seats 73, and guide rack plates 78 are fixedly installed on the outer walls of both limiting seats 73. The outer walls of the two guide rack plates 78 are meshed with the outer walls of the main gear 77. The bottom of the main gear 77 is rotatably installed inside the mounting bracket 71, and the outer walls of the two guide rack plates 78 are slidably connected. Inside the limiting block 76, two guide sliders 74 are symmetrically installed at the bottom of the two limiting seats 73 and the guide sliders 74 are slidably connected to the two guide rails 75. Limiting frames 79 are fixedly installed on the upper end of the two limiting seats 73, and positioning clamps 791 are fixedly installed on the outer wall of one end of the limiting frame 79. Anti-slip pads 792 are fixedly attached to the outer wall of the positioning clamps 791. A limiting plate 793 is fixedly installed on the upper end of the mounting frame 71, and the two limiting frames 79 are symmetrically slidably connected inside the limiting plate 793.

[0026] Two guide sliders 74 are evenly arranged at the bottom of the limiting seat 73, so that the two guide sliders 74 slide on the guide rail 75, which facilitates the relative movement and limiting of the two limiting seats 73. At the same time, the outer walls of the two guide rack plates 78 are slidably connected to the inside of the limiting block 76 when they move relative to each other, thereby limiting the guide rack plates 78. Furthermore, anti-slip pads 792 are provided on the inner and outer walls of the two positioning clamps 791, and the anti-slip pads 792 are made of rubber.

[0027] The operating principle and process of this utility model are as follows: The operator places the silicone roller on the conveyor frame 5 inside the machine frame 1 according to the diameter and thickness. The operator selects the corresponding process parameter group via the touchscreen on the control panel 2. Then, the conveyor motor transports the silicone roller through the conveyor frame 5 into the preheating box 3. At this time, the positioning cylinder 72 inside the drive mounting frame 71 drives the limiting frame 79 on the limiting seat 73 to move. This movement causes the limiting seat 73 to rotate by engaging the main gear 77 with the guide rack plate 78. Simultaneously, the main gear 77 drives another guide rack plate 78 to engage and move, thereby causing the limiting frame 79 on the other limiting seat 73 to move relative to it. Both limiting frames 79 simultaneously drive the positioning clamping plate 791 to slide relative to each other along the inner groove of the limiting plate 793, positioning and clamping the silicone roller. Then, the heating tube inside the preheating box 3 is activated. The heating power of the heating element 82 and drive motor 84 is adjusted according to feedback from temperature sensor 83 to stabilize the preheating zone temperature at 80-120℃. The drive motor 84 drives the fan 85 to rotate, blowing hot air from the heating element 82 onto the silicone roller. At the same time, the adjusting cylinders 87 on the two positioning seats 86 retract, causing the guide plate 88 to rotate along the positioning rod 89 as the axis. This allows fresh air to be blown obliquely into the preheating zone through the guide plate 88. Guided by the guide plate 88, the air flows radially along the roller, uniformly heating the roller. The preheating time is continuous, raising the overall temperature of the roller to the preheating temperature, avoiding direct entry into the high-temperature zone which could cause coating cracking. After preheating, the roller conveyor frame 5 slowly enters the hardening treatment zone. The system activates the heating element 82 in the hardening zone, raising the temperature to 180-220℃. Simultaneously, the temperature sensor 83 monitors the humidity inside the chamber in real time. If the humidity is >30%, the system will detect the problem. RH, the dehumidification device starts automatically, and the high-temperature airflow acts evenly on the surface of the rotor through the guide plate 88. The silicone coating cross-links and cures at high temperature, enhancing the bonding force with the substrate and ensuring that the coating hardens evenly in every place.
