Description

Technical Field

[0001] This utility model relates to the field of irradiation technology, specifically a point-type infrared irradiation device. Background Technology

[0002] In the manufacturing and operation of motors, the application of various adhesives and coatings relies on curing processes to achieve their basic functions. To accommodate the complex structure and large size of motor equipment, two methods are commonly used: room temperature curing and hot air curing. However, room temperature curing suffers from long cycles and low efficiency; hot air curing, on the other hand, is energy-intensive and inconvenient to operate, especially in localized repair scenarios where the high-temperature heating range is difficult to control precisely, easily leading to deterioration of surrounding areas that do not require heating due to high temperatures.

[0003] In existing technologies, although a fixed-size outlet hole can be set at the infrared irradiation output end to achieve local irradiation, the hole diameter cannot be adjusted, making it difficult to flexibly match the diverse heating area requirements in actual repair processes. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a point infrared irradiation device to solve the problem that the diameter of the emission hole is not easy to adjust when heating by infrared irradiation device in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a point-type infrared irradiation device, comprising a housing, an infrared irradiation source, a controller, several sliding plates, a rotating plate, and a vertical adjustment assembly. The housing is a cylindrical shell structure. The infrared irradiation source is fixedly installed on the top inner side of the housing. An emission hole is provided at the center of the bottom of the housing. The sliding plates are fan-shaped structures formed by evenly dividing a circular plate, with the number of evenly divided plates corresponding to the total number of sliding plates. The sliding plates are horizontally installed at the bottom of the housing and surround the axis of the emission hole. The rotating plate is connected to the sliding plates to adjust the size of the adjustment holes at the center positions of the several sliding plates. The vertical adjustment assembly is slidably connected to the housing in the vertical direction to control the rotation angle of the rotating plate. The controller is fixedly installed on the outside of the housing and is electrically connected to the infrared irradiation source.

[0006] The working principle of this invention is as follows: the device adjusts the size of the emission orifice through linear motion.

Place NarrativeThe sliding connecting block and the sliding groove are adapted to each other. The rotating plate is horizontally arranged on the bottom surface of the sliding plate. The center of the rotating plate is provided with a through hole coaxial with the ejection hole. Several guide grooves are arranged around the rotating plate. The pushing column and the guide groove are adapted to each other.

[0008] Preferably, the vertical adjustment assembly includes an adjustment ring and several guide rods. The guide rods surround the outside of the housing and are parallel to the axis of the housing. One end of the guide rod is fixedly connected to the rotating plate, and the other end of the guide rod extends towards the top of the housing.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] like Figure 1 , 2As shown in Figure 5, a point-type infrared irradiation device includes a housing 1, an infrared irradiation source, a controller, several sliding plates 6, a rotating plate 4, and a vertical adjustment assembly. The housing 1 is a cylindrical shell structure made of stainless steel with a thickness of 0.5-1.5 mm. The infrared irradiation source is fixedly installed on the top inner side of the housing 1, with the irradiation direction facing downwards. An emission hole 11 is provided at the center of the bottom of the housing 1. The diameter of the emission hole 11 is approximately half the diameter of the housing 1. The sliding plates 6 are fan-shaped structures formed by evenly dividing a circular plate, with the number of evenly divided plates corresponding to the total number of sliding plates 6. The sliding plates 6 are horizontally installed at the bottom of the housing 1 and surround the axis of the emission hole 11. The rotating plate 4 is connected to the sliding plates 6 and is used to adjust the size of the adjustment holes 9 at the center positions of the several sliding plates 6. The vertical adjustment assembly is slidably connected to the housing 1 in the vertical direction to control the rotation angle of the rotating plate 4. The controller is fixedly installed on the outside of the housing 1 and is electrically connected to the infrared irradiation source. The controller is used to switch the infrared irradiation source on and off, adjust its power, and time it. The controller is equipped with a PLC LCD control panel.

[0026] like Figure 2 , 5 As shown, preferably, an extension plate is provided outside the arc-shaped edge of the sliding plate 6. A sliding connecting block 14 is fixedly provided on one side of the extension plate, and a pushing column 7 is provided on the other side of the extension plate. A regular polygonal sliding groove 10 is provided on the bottom surface of the housing 1. The number of sides of the sliding groove 10 corresponds to the number of sliding plates 6. The axis of the sliding groove 10 coincides with the axis of the emission hole 11. The sliding connecting block 14 is adapted to the sliding groove 10. The rotating plate 4 is horizontally arranged on the bottom surface of the sliding plate 6. A through hole coaxial with the emission hole 11 is provided at the center of the rotating plate 4. Several guide grooves 8 are arranged around the rotating plate 4. The pushing column 7 is adapted to the guide grooves 8. The sliding connecting block 14 has a cuboid structure. The two sides of the sliding plate 6 are in sliding contact with the bottom surface of the housing 1 and the top surface of the rotating plate 4, respectively.

[0027] In this embodiment, by driving the rotating plate 4 to rotate, the guide groove 8 with a specific angle on its surface cooperates with the push column 7 on the sliding plate 6 to convert the circular motion of the rotating plate 4 into the synchronous radial linear motion of multiple fan-shaped sliding plates 6. Under the constraint of the bottom sliding groove 10, these sliding plates 6 converge towards the center or diffuse outward like aperture blades, thereby continuously and precisely adjusting the size of their central light-transmitting aperture.

[0028] like Figure 2 , 3As shown in Figure 4, preferably, the vertical adjustment assembly includes an adjustment ring 2 and several guide rods 3. The guide rods 3 surround the outside of the housing 1 and are parallel to the axis of the housing 1. One end of the guide rod 3 is fixedly connected to the rotating plate 4, and the other end of the guide rod 3 extends towards the top of the housing 1. The adjustment ring 2 is sleeved on the outside of the housing 1, and the outside of the adjustment ring 2 is slidably connected to the guide rod 3. The sliding direction of the adjustment ring 2 is consistent with the extension direction of the guide rod 3. Several spiral grooves 16 are arranged around the outer wall of the housing 1, and several rollers 15 are fixedly arranged on the inner side of the adjustment ring 2. The rollers 15 and the side walls of the spiral grooves 16 are in rolling contact. In this embodiment, a sliding groove 10 is provided on the side of the guide rod 3 near the housing 1, and a guide block 17 is fixedly arranged on the outer wall of the adjustment ring 2. The guide block 17 and the sliding groove 10 are slidably engaged. In this embodiment, two spiral grooves 16 are provided. The guide rod 3 and the housing 1 are spaced apart to reduce resistance.

[0029] In this embodiment, the operator moves the adjusting ring 2, which is fitted onto the outside of the housing 1, up and down. The roller 15 on its inner side then rolls along the spiral groove 16 on the wall of the housing 1, converting the vertical linear motion into the rotational motion of the adjusting ring 2. Since the adjusting ring 2 is fixedly connected to the rotating plate 4 at the bottom via the guide rod 3, the guide rod 3 transmits the rotational motion to the rotating plate 4, thereby precisely controlling its rotation angle. This achieves indirect control of the internal mechanism's rotation through vertical linear motion. The cooperation between the spiral groove 16 and the roller 15 provides smooth transmission.

[0030] like Figure 2 As shown, preferably, an annular groove 12 is provided on the top outer wall of the housing 1. The annular groove 12 has a T-shaped cross-section, and a connector adapted to the annular groove 12 is provided on the top of the guide rod 3. The cooperation between the T-shaped groove and the connector allows the guide rod 3 to slide smoothly up and down with the adjusting ring 2 to transmit rotational motion, while effectively preventing the guide rod 3 from coming out of the annular groove 12, thus ensuring the stability and reliability of the mechanism's operation.

[0031] Preferably, the interior of the housing 1 is coated with an infrared reflective coating, and the side of the sliding plate 6 closest to the housing 1 is also coated with an infrared reflective coating. By applying infrared reflective coatings to the inner wall of the housing 1 and the surface of the sliding plate 6, the energy loss of infrared radiation can be greatly reduced, and the radiation can be efficiently reflected and focused onto the emission port 11, thereby significantly improving irradiation efficiency and energy utilization.

[0032] Preferably, the top of the housing 1 is provided with a handle 13 to facilitate the movement of the device by the staff.

[0033] Preferably, the infrared irradiation source is a silicon carbide heating ceramic plate with a power of 0.3-5 kW. The area of ​​the silicon carbide heating ceramic plate corresponds to the size of the emission aperture 11.

[0034] Preferably, a scale is vertically installed on the side wall of the housing 1, and the staff can use the scale to check the size of the adjustment hole 9.

[0035] Preferably, the bottom of the rotating plate 4 is surrounded by several support columns 5. In this embodiment, three support columns 5 are provided to reduce the contact area with the motor and to facilitate effective support in uneven locations.

[0036] Preferably, the number of sliding plates 6 is 5-10 pieces, which avoids the problems of excessive mechanical structure, decreased reliability and increased manufacturing cost caused by too many sliding plates 6, and achieves the optimal balance between accuracy and reliability.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
