Description

Technical Field

[0001] This utility model relates to the field of polishing roller drying technology, and in particular to a polishing roller constant temperature control drying device. Background Technology

[0002] In the field of precision manufacturing, the quality stability of polishing rollers directly affects the surface treatment effect of workpieces. Traditional natural air drying methods not only take 12 to 24 hours, but also make it difficult to ensure uniform drying of different parts of the roller, resulting in defects such as color difference and streaks during polishing. As the requirements for surface precision in high-end equipment manufacturing become increasingly stringent, the moisture content fluctuation of polishing rollers must be controlled within ±0.5%, which places extremely high demands on the temperature control accuracy and hot air distribution uniformity of drying equipment.

[0003] The polishing roller drying equipment commonly used in the industry is mainly based on the principle of static hot air circulation. A typical structure includes a box-type drying chamber and an axial blower. Its working principle is as follows: hot air is blown unidirectionally into the sealed chamber by the blower, and heat is indirectly transferred using metal heat-conducting plates. The equipment typically uses contact temperature sensors to monitor the air temperature inside the chamber and relays to control the start and stop of the heating elements.

[0004] Existing drying equipment has a problem: uneven hot air distribution leads to inconsistent drying effects. Due to the use of single-point air inlet and static placement, the hot air forms a significant temperature gradient inside the chamber. This uneven drying causes differences in the fiber shrinkage rate of the polishing rollers, which in turn results in uneven pressure distribution during polishing, seriously affecting the surface treatment quality of the workpiece. Therefore, a constant temperature control drying device for polishing rollers is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a constant temperature control drying device for polishing rollers, which aims to improve the problem that uneven drying leads to differences in the fiber shrinkage rate of polishing rollers, resulting in uneven pressure distribution during polishing and seriously affecting the surface treatment quality of workpieces.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature control drying device for polishing rollers, comprising a box body, a sealing cover fixedly connected to the outer wall of the box body, a fan on one side of the outer wall of the box body, a pipe fixedly connected to the output end of the fan, a fixing block fixedly connected to one end of the pipe, the outer wall of the fixing block fixedly connected to the inner wall of the box body, a flow divider fixedly connected to the inner wall of the box body, a motor fixedly connected inside the box body, and a limit component provided at the output end of the motor;

[0007] The limiting component includes connecting block one, connecting block two, limiting block and connecting block three. The inner wall of connecting block one is fixedly connected to the motor output end, the outer wall of connecting block two is fixedly connected to the inner wall of connecting block one, the outer wall of limiting block is slidably connected to the inner wall of connecting block two, and the outer wall of connecting block three is fixedly connected to the inner wall of connecting block two.

[0008] Furthermore, the outer wall of the limiting block is slidably connected to the inner wall of the connecting block three, and the inner wall of the connecting block two is slidably connected to the polishing roller body.

[0009] Furthermore, the outer wall of the polishing roller body is rotatably connected to the inner wall of the box, and the inner wall of the sealing cover is fixedly connected to the outer wall of the motor.

[0010] Furthermore, a second fan is provided on the other side of the outer wall of the box, and a second pipe is fixedly connected to the output end of the second fan, and a third pipe is fixedly connected to the input end of the second fan.

[0011] Furthermore, the outer wall of the second pipe is fixedly connected to the inner wall of the box, and the outer wall of the third pipe is fixedly connected to a heating tank.

[0012] Furthermore, a pipe four is fixedly connected to the inner wall of the heating tank, and the outer wall of the pipe four is fixedly connected to the inner wall of the tank.

[0013] Furthermore, a diversion pipe is fixedly connected to the inner wall of the heating tank, and the outer wall of the diversion pipe is fixedly connected to the inner wall of a pipeline.

[0014] Furthermore, a heating block is fixedly connected to the outer wall of the second pipe, and a heating wire is fixedly connected to the inner wall of the heating block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the polishing roller body is placed inside the connecting block two. By holding the limiting block and sliding it in the grooves of connecting block two and connecting block three, the polishing roller body is limited. Hot air is delivered to pipe one by fan one and then delivered from the fixed block to the box for hot air drying. The hot air is divided by the diverter plate to make the polishing roller body dry evenly. At the same time, the motor drives connecting block one to rotate, so that connecting block two drives the polishing roller body to achieve a uniform heating effect, thereby improving the practicality of the device.

[0017] 2. In this utility model, the hot air that has cooled down comes into the heating tank through pipe four. The hot air is then transported into the heating tank through a diversion pipe for preliminary heating. The hot air in the heating tank is then transported from pipe three to the heating block by fan two. The heating block undergoes secondary heating through the heating wire. The heated air is then transported back into the box through pipe two for waste heat utilization, reducing heat energy waste and thus improving the practicality of the device.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-4This utility model provides an embodiment of a constant temperature control drying device for polishing rollers, comprising a housing 1, which is the main part of the drying device. The housing 1 has an internal sealing strip to form a sealed drying space. The internal temperature is controlled by a controller, and an observation window is installed to monitor the drying effect at any time. A sealing cover 2 is fixedly connected to the outer wall of the housing 1. The sealing cover 2 is fitted to the edge of the housing 1 through a sealing strip to prevent hot air leakage from the connection point, ensuring stable internal temperature and avoiding a decrease in drying efficiency due to heat loss. A fan 3 is installed on one side of the outer wall of the housing 1, and the output end of the fan 3 is fixed... A pipe 4 is fixedly connected to one end of the pipe 4, and a fixing block 14 is fixedly connected to one end of the pipe 4. The fixing block 14 accurately guides the hot air delivered by the fan 3 into the interior of the box 1, and at the same time, it supports the pipe and fixes the direction of the hot air flow. The outer wall of the fixing block 14 is fixedly connected to the inner wall of the box 1. A diverter plate 5 is fixedly connected to the inner wall of the box 1. The diverter plate 5 evenly distributes the incoming hot air, dispersing the concentrated hot air flow to all circumferential parts of the polishing roller body 6, eliminating the drying blind zone, and ensuring the uniformity of the roller body's axial and circumferential heating. A motor 15 is fixedly connected inside the box 1, and a limit component is set at the output end of the motor 15.

[0028] The limiting assembly includes connecting block 16, connecting block 27, limiting block 18, and connecting block 39. The inner wall of connecting block 16 is fixedly connected to the output end of motor 15. Connecting block 16 drives the polishing roller body 6 to rotate, ensuring the stability of power transmission during rotation. The outer wall of connecting block 27 is fixedly connected to the inner wall of connecting block 16. Connecting block 27 cooperates with limiting block 18 through a groove to fix the position of the polishing roller and drive it to rotate. The outer wall of limiting block 18 is slidably connected to the inner wall of connecting block 27. The outer wall of connecting block 39 is fixedly connected to the inner wall of connecting block 27. The outer wall of limiting block 18 is slidably connected to the inner wall of connecting block 39. The polishing roller body 6 is slidably connected to the inner wall of connecting block 27.

[0029] Reference Figures 1-6The outer wall of the polishing roller body 6 is rotatably connected to the inner wall of the housing 1. The inner wall of the sealing cover 2 is fixedly connected to the outer wall of the motor 15. A second fan 7 is provided on the other side of the outer wall of the housing 1. The output end of the second fan 7 is fixedly connected to a second pipe 9, and the input end of the second fan 7 is fixedly connected to a third pipe 10. The outer wall of the second pipe 9 is fixedly connected to the inner wall of the housing 1. The second pipe 9 re-sends the high-temperature hot air after secondary heating back into the housing 1, completing the hot air recycling and reducing heat loss. The outer wall of the third pipe 10 is fixedly connected to a heating tank 12, which receives the pipe. The low-temperature hot air conveyed by the fourth pipe 11 is evenly dispersed through the diversion pipe 13 to initially raise the temperature of the low-temperature hot air in preparation for secondary heating. The inner wall of the heating tank 12 is fixedly connected to the fourth pipe 11, and the outer wall of the fourth pipe 11 is fixedly connected to the inner wall of the box 1. The inner wall of the heating tank 12 is fixedly connected to the diversion pipe 13, and the outer wall of the diversion pipe 13 is fixedly connected to the inner wall of the first pipe 4. The outer wall of the second pipe 9 is fixedly connected to the heating block 8, and the inner wall of the heating block 8 is fixedly connected to the heating wire 20. The heating wire 20 performs secondary heating on the hot air conveyed by the second fan 7.

[0030] Working Principle: When the polishing roller body 6 needs to be dried, it is first placed into the connecting block 2 17. By holding the limiting block 18 and sliding it along the grooves of the connecting block 2 17 and the connecting block 3 19, it is precisely locked into the limiting groove, thus achieving a stable limiting of the polishing roller body 6 and preventing displacement during the drying process. Subsequently, the fan 1 3 is started, drawing in and heating the outside air to form high-temperature hot air. The hot air is transported to the fixing block 14 through the pipe 1 4 and finally sent into the chamber 1 for drying. The diverter plate 5 evenly distributes the hot air to all parts of the polishing roller body 6, effectively eliminating drying blind spots and ensuring uniform heating of the roller body. At the same time, the motor 15 operates synchronously, driving the connecting block 1 16 to rotate, which in turn drives the connecting block 2 17 and the polishing roller body 6 to rotate synchronously. This dynamic rotation design allows the polishing roller body 6 to receive hot air baking from all directions without dead angles during the drying process, further improving the uniformity of heating. The sealing cover 2 is tightly fastened to the chamber 1, and its edges adopt a precision sealing structure to prevent the chamber 1 from being sealed with the sealing cover. A gap appears at the connection of the cover 2 to prevent hot air leakage and temperature drop inside the chamber, ensuring the stability of the drying effect. As drying continues, the hot air that has cooled down flows into the heating tank 12 through pipe 4 11. Inside the heating tank 12, the diverter pipe 13 evenly disperses the recovered hot air, completing the initial preheating treatment. Then, the fan 2 7 transports the preheated hot air to the heating block 8 through pipe 3 10. The heating wire 20 inside the heating block 8 performs secondary deep heating on the hot air, so that the hot air reaches the set temperature standard again. Finally, the hot air that has been reheated is transported back into the chamber 1 through pipe 2 9, realizing the recycling of waste heat, greatly reducing heat loss, and effectively improving the energy utilization efficiency of the equipment.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
