The top surface of the first conveying platform 111 is inclined, which facilitates the rolling of the finned tube 8 after it is placed on the first conveying platform 111. Multiple pushers 113 are evenly distributed along the length of the top surface of the first conveying platform 111. Each pusher 113 includes a baffle block 1131 disposed at the lower end of the inclined surface of the first conveying platform 111 and a first pusher cylinder 1132. 132 is located on the lower end of the partition block 1131 away from the inclined surface of the conveying platform.

The partition block 1131 is used to block the finned tubes 8 that roll down to the lower end of the first conveying platform 111. Then, the first push cylinder 1132 pushes the finned tubes 8 one by one upward and rolls them down into the conveying guide rail 112 through the upper end face of the partition block 1131.

[0055] refer to Figure 1 , Figure 2 and Figure 4 The length of the conveying guide rail 112 is less than the length of the finned tube 8.

The upper pressure roller group 22 includes driven rollers 221 that correspond one-to-one with the drive rollers 211 and a first lifting member 222 that drives the driven rollers 221 to move longitudinally. The driven rollers 221 are also inclined and in the opposite direction to the inclination of the drive rollers 211. When the straightening device 2 of this structure is working, it can straighten the finned tube 8 during the conveying process, and the straightened finned tube 8 enters the second feeding assembly 12.

[0057] refer to Figure 1 and Figure 4 The second feeding assembly 12 includes a second conveying platform 121 with an inclined top, a supporting guide rail 122 disposed at the discharge end of the second conveying platform 121, and a conveying roller assembly 123 disposed on one side of the supporting guide rail 122.

During operation, the finned tube 8 is pushed by the second push cylinder 124, causing the finned tube 8 to roll into the support guide rail 122. The end part of the finned tube 8 is placed on the lower drive roller 1231. At this time, the finned tube 8 is moved along the support guide rail 122 with the cooperation of the lower drive roller 1231 and the upper driven roller 1232, which facilitates the subsequent conveying device 3 to pick up and convey the finned tube 8.

[0058] refer to Figure 8 and Figure 9The conveying device 3 includes at least two rows of movable support plates 31 arranged parallel to each other and a second driving member 35 that drives the at least two rows of movable support plates 31 to move.

During operation, when the movable support plate 31 is driven up and down by the second driving component 35, the finned tube 8 on the support rail 122 can be picked up and transferred to the movable support plate 31. Subsequently, under the action of the movable support plate 31 and the fixed support plate 32, the finned tube 8 is sequentially conveyed to the length-fixing device 4, the cutting device 5, and the chamfering device 6 for processing.

[0059] refer to Figure 8 The length-fixing device 4 includes a length-fixing plate 41 and a length-fixing cylinder 42 that drives the length-fixing plate 41 to move laterally back and forth. When the conveying device 3 conveys each finned tube 8 to the length-fixing device 4, the length-fixing cylinder 42 drives the length-fixing plate 41 to push the end of the finned tube 8, so that the end of the finned tube 8 is in a flat state. When the subsequent cutting device 5 cuts the other end of the finned tube 8, it ensures that the length of the cut finned tube 8 is the same.

[0060] refer to Figure 8 , Figure 10 and Figure 11 The cutting device 5 includes a support frame 51, a cutting component 52, and a second lifting component 53 mounted on the support frame 51 for driving the cutting component 52 to move longitudinally. The cutting component 52 includes a cutting wheel 521 and a cutting motor 522 that drives the cutting wheel 521 to rotate. When cutting the finned tube 8, the second lifting component 53 drives the cutting component 52 to move downward, thereby realizing the cutting of the finned tube 8. It also includes a clamping component 54 for fixing the end of the finned tube 8 to be cut. The clamping component 54 is located on one side of the feed end of the cutting device 5. The clamping component 54 adopts a cylinder jaw. The clamping component 54 fixes the finned tube 8 to be cut, so that the finned tube 8 is not easy to move during cutting, which facilitates the cutting component 52 to cut the finned tube 8.

[0061] refer to Figure 8The chamfering device 6 and the cutting device 5 are located on the same side. The chamfering device 6 includes a knife holder 61 and a third drive motor 62 that drives the knife holder 61 to rotate. The knife holder 61 is equipped with an inner chamfering knife 63 and an outer chamfering knife 64. The third drive motor 62 drives the knife holder 61, which is equipped with an inner chamfering knife 63 and an outer chamfering knife 64, to rotate, which can simultaneously perform inner and outer chamfering on the finned tube 8, thereby improving the chamfering efficiency. When performing inner and outer chamfering, it is also fixed by a fastener (not shown in the figure).

[0062] In summary, this complete system for continuous processing of finned tubes 8 can achieve uninterrupted and continuous conveying and processing of finned tubes 8, improving processing efficiency; moreover, it has a simple structure, is easy to process and manufacture, and has a low cost.
