Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically to a winged flat tube feeding and positioning mechanism. Background Technology

[0002] Finned heat exchange tubes are highly efficient heat transfer elements. By adding fins to the outer surface of the base tube, the heat exchange area is significantly increased, thereby improving heat transfer efficiency. Flying-blade flat tubes are manufactured through a continuous slicing process on the surface of aluminum alloy (or other machinable materials). Their heat dissipation fins are directly formed on the outer wall of the fluid pipe, achieving contactless thermal resistance during heat conduction and further enhancing heat transfer efficiency. Currently, flying-blade flat tubes are widely used in air conditioning and refrigeration, petrochemicals, power plants, waste heat recovery, and other fields.

[0003] With the increasing application of wing-shaped flat tubes, the demand for processing wing-shaped flat tubes according to different working conditions has also increased. Before processing, the wing-shaped flat tube after fin cutting needs to be positioned to ensure that it is in the predetermined position and to avoid dimensional deviations caused by movement or shaking. Because the fins cut from the outer walls on both sides of the wing-shaped flat tube are thin and closely arranged, the fins are easily deformed or cannot be accurately positioned due to uneven pressure during the positioning process. Therefore, there is an urgent need to develop a positioning mechanism suitable for wing-shaped flat tubes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model discloses a wing-shaped flat tube feeding and positioning mechanism, which can solve the problem of fins being easily deformed by pressure during the positioning of existing wing-shaped flat tubes and improve positioning accuracy.

[0005] To achieve the above technical objectives, this utility model proposes a wing-shaped flat tube feeding and positioning mechanism, comprising a support base and a roller assembly rotatably connected to the support base, wherein: The support base includes an upper base plate, a side plate, and a lower base plate, forming a space for connecting the roller assembly; The roller assembly includes a first roller and a second roller arranged along the conveying direction of the wing flat tube; the first roller and the second roller are arranged opposite to or offset to form a first channel for accommodating and squeezing the upper and lower ribs of the wing flat tube, and the main bodies of the first roller and the second roller are provided with radially recessed notches in the circumference, and the notches on the first roller and the second roller cooperate to form a second channel for accommodating the wings on the left and right sides of the wing flat tube.

[0006] In a further example of this utility model, the roller shaft of the first roller is fixed to the upper and lower base plates of the support by a lateral elastic displacement component; wherein, the lateral elastic displacement component includes: a lateral guide hole provided on the upper and lower base plates of the support, the roller shaft of the first roller being slidably inserted through the guide hole; at least one elastic reset component, the two ends of which respectively abut against the roller shaft of the first roller and the upper or lower base plate of the support, so that the roller shaft of the first roller is displaced and automatically reset when subjected to force perpendicular to the conveying direction.

[0007] In a further example of this utility model, the elastic reset member includes a compression spring, which is sleeved on a guide pin, and the guide pin constitutes a guide frame for the spring.

[0008] In a further example of this utility model, the main bodies of the first roller and the second roller are provided with multiple notches from top to bottom in the circumferential direction.

[0009] In a further example of this utility model, the outline of the notch is adapted to the shape of the cross-section of the wing on the left and right sides of the wing flat tube.

[0010] In a further example of this utility model, the rollers of the first roller and the second roller are fixed to the upper and lower base plates of the support base by bearings.

[0011] In a further example of this invention, the number of the first roller and / or the second roller is at least two.

[0012] In a further example of this invention, the first roller and the second roller are misaligned.

[0013] In a further example of this utility model, the first roller and / or the second roller are connected by a roller drive structure.

[0014] In a further example of this utility model, the support base is connected to a fixed bracket.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: The wing-shaped flat tube feeding and positioning mechanism of this utility model provides a first channel for clamping the upper and lower ribs of the wing-shaped flat tube through the relative or staggered arrangement of the first and second rollers, thereby achieving precise positioning during the positioning process. Furthermore, by providing notches on the main bodies of the first and second rollers to form a space for accommodating the wing, pressure is avoided on the wing on both sides of the wing-shaped flat tube during positioning and conveying, solving the problem of wing deformation under pressure during the positioning process. This utility model's wing-shaped flat tube feeding and positioning mechanism has a simple structure, is easy to operate, and has excellent practicality. Attached Figure Description

[0023] Example 1

[0024] A flying wing flat tube feeding and positioning mechanism, such as Figure 1 As shown, it includes a support base and a roller assembly rotatably connected to the support base, wherein: The support base includes an upper base plate 11, a side plate 12 and a lower base plate 13, forming a space for connecting the roller assembly; The roller assembly includes a first roller 21 and a second roller 22 arranged along the conveying direction of the wing flat tube; the first roller 21 and the second roller 22 are arranged opposite to or staggered to form a first channel 23 for accommodating and squeezing the upper and lower ribs of the wing flat tube, and the main body of the first roller 21 and the second roller 22 is provided with a radially recessed notch in the circumference, and the notches on the first roller 21 and the second roller 22 cooperate to form a second channel 24 for accommodating the wings 32 on the left and right sides of the wing flat tube.

[0025] Combination Figure 1 and Figure 2 The diagram illustrates the first channel 23 and the second channel 24 formed by the cooperation of the first roller 21 and the second roller 22 in the wing-shaped flat tube feeding and positioning mechanism of this utility model. The rollers in this embodiment include a roller shaft and a main body; the roller shaft is rotatably connected to the upper base plate 11 and the lower base plate 13 of the support seat, respectively, and the main body directly contacts the input wing-shaped flat tube in the circumferential direction and applies a positioning force to it.

[0026] It should be noted that, in combination Figure 3In this embodiment, the flying wing flat tube includes a flow channel and flying wings 32 shoveled on the two wider sides of the flow channel (i.e., the left and right sides of the flying wing flat tube). The two narrower sides of the flow channel (i.e., the upper and lower sides of the flying wing flat tube) are provided with raised ribs 31. It should be noted that, because the flying wings 32 shoveled on both sides of the flying wing flat tube are thin and densely arranged, for the sake of brevity... Figure 3 The structure of a single flying wing 32 is not shown in the figure.

[0027] In this embodiment, during the operation of the feeding and positioning mechanism, the winged flat tube is first fed between the first roller 21 and the second roller 22, which are arranged opposite to or staggered. The protruding ribs 31 on the upper and lower sides of the winged flat tube are respectively accommodated and compressed by the upper and lower sections of the first channel 23, while the wings on the left and right sides enter the second channel 24 formed by the interlocking notches on the first roller 21 and the second roller 22. As the winged flat tube is conveyed forward, the second channel 24 protects the wings 32, and the first channel 23 achieves stable straightening of the entire winged flat tube through the compression of the protruding ribs 31. In actual straightening, an external force can be applied to the outer end of the winged flat tube to propel it along the conveying direction.

[0028] Example 2

[0029] Based on the wing-shaped flat tube feeding and positioning mechanism shown in Embodiment 1, this embodiment optimizes the connection structure between the first roller 21 and the base.

[0030] Combined Figure 4 Optionally, the roller of the first roller 21 is fixed to the upper base plate 11 and the lower base plate 13 of the support seat by a lateral elastic displacement component; wherein, the lateral elastic displacement component includes: a lateral guide hole 251 provided on the upper base plate 11 and the lower base plate 13 of the support seat, the roller of the first roller 21 being slidably inserted in the guide hole 251; at least one elastic reset component 252, the two ends of which respectively abut against the roller of the first roller 21 and the upper base plate 11 or the lower base plate 13 of the support seat, so that the roller of the first roller 21 is displaced and automatically reset when subjected to horizontal force perpendicular to the conveying direction.

[0031] Alternatively, the roller of the first roller 21 is rotatably connected to the upper base plate 11 and the lower base plate 13 of the support seat via bearings, and one end of the elastic reset member 252 abuts against the bearing.

[0032] Optionally, the second roller 22 is fixedly connected to the upper base plate 11 and the lower base plate 13 of the support. Figure 5 The diagram shows a structural diagram of the upper base plate 11 in this embodiment, wherein the roller of the second roller 22 is mounted on the upper base plate 11 and the lower base plate 13 through the roller mounting hole 253.

[0033] In this embodiment, the rollers of the second roller 22 are rotatably connected to the upper base plate 11 and the lower base plate 13 of the support to form a fixed roller group. Multiple second rollers 22 are arranged in a line along the conveying direction, providing continuous support for the straightening of the wing flat tube. The rollers of the first roller 21 are connected to the upper base plate 11 and the lower base plate 13 of the support through a lateral elastic displacement component to form a floating roller group. Thus, in actual operation, when the wing flat tube enters the feeding and positioning mechanism, its rib 31 first contacts the floating roller group. Under the preload of the compression spring 252, the first roller 21 will generate a lateral elastic displacement, continuously applying radial pressure to the wing flat tube, forcing the tube to move closer to the second roller group. This achieves dynamic clamping and positioning of the wing flat tube and can automatically adapt to tubes with different flow channel sizes through elastic deformation.

[0034] This also increases the clamping capacity of the roller assembly on the rib 31 of the wing-shaped flat tube, improving straightening accuracy and operational flexibility. Further optional, such as... Figure 4 As shown, the elastic reset member 252 includes a compression spring, which is sleeved on a guide pin, and the guide pin constitutes a guide frame for the spring.

[0035] Example 3

[0036] Based on the wing-shaped flat tube feeding and positioning mechanism shown in Embodiment 1, this embodiment optimizes the structure of the notch portion on the first roller 21 and the second roller 22.

[0037] Optionally, a second channel 24 is provided circumferentially on the main body of the first roller 21 and the second roller 22. By providing multiple radially recessed notches from top to bottom circumferentially on the first roller 21 and the second roller 22, multiple vertically arranged first channels 23 and second channels 24 can be formed. This allows for the simultaneous positioning of multiple wing-shaped flat tubes as needed during actual operation, meeting the processing requirements of diverse downstream processing steps.

[0038] Optionally, the contour of the notch is adapted to the shape of the cross-section of the left and right wings 32 on both sides of the winged flat tube. This helps to protect the wings 32 on both sides of the winged flat tube during the positioning process and improves the stability of the feeding and positioning mechanism of this utility model.

During the positioning process, the roller group rotates in coordination with the flying wing flat tube to move along the conveying direction.

[0042] Optionally, the number of first rollers 21 and / or second rollers 22 is at least two. By arranging at least two first rollers 21 or second rollers 22 in a line along the conveying direction of the wing flat tube, the positioning accuracy is improved.

[0043] Optionally, the first roller 21 and the second roller 22 are staggered along the conveying direction of the wing flat tube. Through the cooperation of the first roller 21 and the second roller 22, pressure is applied to the wing flat tube evenly from different angles to achieve more thorough positioning.

[0044] Example 5

[0045] Based on the wing-shaped flat tube feeding and positioning mechanism shown in Embodiment 1, the wing-shaped flat tube can be driven along the conveying direction by applying external force or by a driving mechanism. In this embodiment, optionally, the rollers of the first roller 21 and / or the second roller 22 are connected to the driving structure, thereby driving the wing-shaped flat tube forward through the rotation of the roller group to achieve positioning.
