Description

Technical Field

[0001] This utility model relates to the field of sleeve support roller technology, specifically to an infrared drying and coating device for sleeve support rollers. Background Technology

[0002] In the complex systems of modern industrial production, sleeved support rollers, with their unique structure and performance, have become indispensable key mechanical components in many industries such as metallurgy, papermaking, and rubber. In the metallurgical industry, sleeved support rollers play a central role in the paper forming and conveying process. Their corrosion resistance is crucial to the service life of the roller body in humid and chemical environments. Once corrosion occurs, it will cause defects on the paper surface and reduce the quality of the paper.

[0003] To significantly improve the overall performance of bushing support rollers, applying wear-resistant coatings and other functional coatings to their surfaces has become a widely adopted and effective method in the industry. In this process, the quality of the coating and subsequent drying processes is like the foundation of a tall building, playing a decisive role in the coating's performance. A high-quality coating process ensures that the coating adheres evenly and firmly to the roller surface, providing stable and long-lasting protection; an efficient and precise drying process allows the coating to cure rapidly, fully realizing its intended functional characteristics.

[0004] However, a review of traditional bushing support roller coating systems reveals significant drawbacks in terms of coating roller adjustment. Traditional designs are often limited to bushing support rollers of specific sizes and specifications. When faced with diverse production demands, requiring the handling of workpieces with varying diameters, lengths, and other specifications, this inflexibility becomes apparent. For example, in some small metallurgical processing plants, processing a batch of bushing support rollers of new specifications requires workers to spend considerable time disassembling, adjusting, and reassembling the equipment's mounting brackets, transmission connections, and other components. Custom-made components may even be necessary. This process not only demands significant effort from skilled technicians but can also lead to equipment malfunctions due to improper operation, severely impacting production efficiency, extending delivery cycles, and reducing the company's competitiveness.

A rotating shaft is rotatably connected to the front of the moving plate near the top. First and second pressure plates are fixedly connected to the front end of the rotating shaft.

[0008] Preferably, the rear end of the stirring shaft is rotatably connected to the back of the inner wall of the coating tank, and a valve switch control device is fixedly connected to the surface of the discharge pipe.

[0009] Preferably, the output end of the second motor is fixedly connected to the top of the screw, and the top of the lifting block has holes on the front and rear sides that match the limiting rod.

[0010] Preferably, the inner wall of the lifting frame has holes on the front and rear sides near the left side that match the coating roller, and the surface of the coating roller passes through and is rotatably connected to the hole. The coating roller is located directly below the discharge pipe, and the first and second pressing plates clamp the bushing support roller.

[0011] Preferably, the drying mechanism includes a box body, which is fixedly connected to the top left side of the base. An air inlet slot is provided on the left side of the box body. A card plate is fixedly connected to the inner wall of the box body near the left side. Fans are equidistantly arranged on the left side of the card plate.

[0013] Preferably, the vent hood corresponds to the sleeved support roller held by the first and second clamping plates.

[0014] Compared with the prior art, the present invention provides an infrared drying coating device for a bushing support roller, which has the following advantages:

[0015] 1. This infrared drying and coating device for bushing support rollers features a first motor driving a stirring shaft within the coating tank. This ensures thorough mixing of the coating liquid, preventing sedimentation or stratification and guaranteeing the stability of the coating liquid's quality. Simultaneously, equidistant discharge pipes at the bottom of the coating tank, along with a valve control device, precisely control the discharge volume and position of the coating liquid, ensuring even dripping onto the coating roller and achieving uniform coating of the bushing support roller surface. A second motor drives a screw to rotate. Because a lifting block is threadedly connected to the screw and limited by a limiting rod, the lifting block can move up and down with the screw's rotation. This allows for flexible adjustment of the height of the lifting frame connected to the lifting block and the coating roller mounted on it. In actual production, the height of the coating roller can be quickly and accurately adjusted according to different sizes of the bushing support rollers and coating process requirements, improving the device's versatility and adaptability.

[0016] 2. This infrared drying coating device for bushing support rollers uses a fan mounted on a clamping plate. Outside air is drawn in through an air inlet slot, heated by electric heating wires, and then circulates within the chamber. This hot air circulation system rapidly transfers heat to the coating surface of the bushing support rollers, accelerating solvent evaporation and improving drying efficiency. Simultaneously, the uniform hot air distribution ensures even drying, preventing localized overheating or overdrying and ensuring stable coating quality. An infrared irradiation lamp located near the top on the right side of the chamber emits infrared rays to radiate and heat the coating. Infrared rays have strong penetrating power, directly affecting the interior of the coating, intensifying molecular vibrations and rapidly increasing temperature, further promoting solvent evaporation. The combination of infrared drying and hot air drying forms a dual drying mechanism, significantly shortening drying time and improving production efficiency. Attached Figure Description

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Please see Figure 1-5 This utility model provides a technical solution: an infrared drying and coating device for a bushing support roller, including a base 1, a support leg 2 fixedly connected to the bottom of the base 1, a coating mechanism 3 provided on the right side of the top of the base 1, and a drying mechanism 4 provided on the left side of the top of the base 1.

[0031] The coating mechanism 3 includes a first fixed frame 31 and a sleeved support roller 325. The first fixed frame 31 is fixedly connected to the top right side of the base 1. A coating tank 32 is fixedly connected to the front and rear sides of the first fixed frame 31 near the top. A first motor 33 is fixedly connected to the front of the fixed frame near the top.

A second motor 38 is fixedly connected to the top of the rectangular frame 36. A lifting block 39 is threaded onto the surface of the screw 37.

The limiting rod 311 limits the lifting block 39, so that the lifting block 39 moves up and down with the rotation of the screw 37.

[0034] The inner wall of the lifting frame 312 has holes on the front and rear sides near the left side that match the coating roller 315. The surface of the coating roller 315 passes through and is rotatably connected to the hole. The coating roller 315 is located directly below the discharge pipe 35. The first pressing plate 319 and the second pressing plate 324 clamp the bushing support roller 325.

[0035] Example 2

[0036] Please see Figure 6-7 Furthermore, based on Example 1, a drying mechanism 4 was obtained.

[0037] The drying mechanism 4 includes a box body 41, which is fixedly connected to the top left side of the base 1. An air inlet slot 42 is provided on the left side of the box body 41. A card plate 43 is fixedly connected to the inner wall of the box body 41 near the left side. Fans 44 are equidistantly arranged on the left side of the card plate 43. An electric heating wire 45 is fixedly connected to the inner wall of the box body 41. An air outlet hood 46 is fixedly connected to the right side of the box body 41 near the top. An infrared irradiation lamp 47 is fixedly connected to the right side of the box body 41 near the top.

[0038] The card plate 43 has a slot on the left side that matches the fan 44, and the fan 44 is fixedly connected to the slot through the surface of the card plate 43.

[0039] The vent 46 corresponds to the bushing support roller 325 held by the first clamping plate 319 and the second clamping plate 324.

[0040] In actual operation, when this device is used, after the first motor 33 starts, its output end drives the stirring shaft 34 to rotate inside the coating tank 32. Since the rear end of the stirring shaft 34 is rotatably connected to the back of the inner wall of the coating tank 32, it can stably stir the coating liquid in the coating tank 32, so that the components of the coating liquid are evenly mixed, preventing sedimentation or stratification, and ensuring the stability of the coating liquid quality. The discharge pipe 35, which is fixedly connected at equal intervals at the bottom of the coating tank 32, can precisely control the discharge amount of the coating liquid according to the coating requirements under the action of the valve switch control device on its surface. When the valve is opened, the coating liquid drips evenly from the discharge pipe 35, the second motor 38 runs, and its output end is fixedly connected to the top of the screw 37, driving the screw 37 to rotate. The lifting block 39 is threadedly connected to the screw 37, and the holes on the front and rear sides of the top of the lifting block 39 match the limiting rod 311. Under the limiting action of the limiting rod 311, the lifting block 39 can only move up and down with the rotation of the screw 37. The lifting frame 312, fixedly connected to the right side of the lifting block 39, also rises and falls accordingly, thereby adjusting the height of the coating roller 315 mounted on the lifting frame 312 to accommodate different sized bushing support rollers 325. The third motor 313 starts, and the first pulley 314 on its output shaft surface drives the second pulley 316 through the belt 317, thereby causing the coating roller 315 to rotate. Since the inner wall of the lifting frame 312 has holes on the front and rear sides near the left side that match the coating roller 315, and the surface of the coating roller 315 passes through and is rotatably connected to the holes, the stability of the rotation of the coating roller 315 is ensured. The rotating coating roller 315 is located directly below the discharge pipe 35, which can evenly absorb the dripping coating liquid on the surface of the coating roller 315. The fourth motor 318 starts, and the first pressure plate 319 at its output end begins to rotate. At the same time, the cylinder 321 near the bottom of the back of the fixed frame works, and its output end pushes the moving plate 322 to move. The second pressure plate 324 at the front end of the rotating shaft 323 rotatably connected to the front of the moving plate 322 near the top moves accordingly. The first clamping plate 319 and the second clamping plate 324 cooperate with each other to firmly clamp the bushing support roller 325, ensuring that the bushing support roller 325 will not shift or shake during the coating process, thus guaranteeing coating accuracy.

[0041] The blower 44 is installed and fixed in the slot on the left side of the clamping plate 43, which is fixed to the inner wall of the housing 41 near the left side. After the blower 44 is started, it draws in outside air through the air inlet slot 42 on the left side of the housing 41. The drawn-in air passes through the electric heating wire 45 on the inner wall of the housing 41, which heats up when energized. The hot air flows inside the housing 41, forming a hot air circulation. Since the blowers 44 are equidistantly arranged on the clamping plate 43, the hot air can be distributed relatively evenly inside the housing 41. The infrared irradiation lamp 47 on the right side of the housing 41 near the top is turned on, emitting infrared rays. The infrared rays directly radiate onto the coating layer on the surface of the bushing support roller 325 entering the drying mechanism 4. The infrared radiation causes the molecules in the coating to absorb energy and vibrate more intensely, resulting in a rapid increase in temperature and promoting solvent evaporation.
