[0033] The present utility model provides a technical solution:

[0034] Embodiment 1

[0035] Combined with Figures 1 to 6 , a flat tube rolling bump device, which includes a base frame 3. A base 4 is arranged on the front side of the base frame 3. A vertical frame 41 is fixedly connected to the top of the base 4. A pressing plate mechanism 1 is arranged inside the bottoms of the base frame 3 and the vertical frame 41.

[0037] The first driving component 11 includes a first driving motor 1101. The first driving motor 1101 is fixedly connected to the inner bottom of the rear side of the base frame 3. A first driving shaft 1102 is fixedly connected to the front side of the first driving motor 1101. The first driving shaft 1102 is rotatably connected to the inside of the front side of the base frame 3. A driving gear 1103 is fixedly connected to the front side of the first driving shaft 1102. The pressing component 12 includes a first rotating shaft 1201. The first rotating shaft 1201 is arranged inside the front and rear sides of the base 4. A bump roller 1202 is fixedly connected to the outer circle of the first rotating shaft 1201. A second rotating shaft 1203 is arranged above the first rotating shaft 1201. The second rotating shaft 1203 is arranged inside the front and rear sides of the vertical frame 41.

A synchronization gear 1303 is meshed with the top of the outer circle of the synchronization gear 1302. The synchronization gear 1303 is fixedly connected to the front and rear sides of the second rotating shaft 1203.

[0038] Further: The staff only needs to start the first driving motor 1101 to drive the bump rollers 1202 and the concave dot rollers 1204 on the upper and lower sides to rotate synchronously and reversely, so that the bump rollers 1202 and the concave dot rollers 1204 on the upper and lower sides cooperate to complete the feeding and pressing processes of the flat tube. The flat tube after bump pressing increases the outer surface area of the flat tube when in use, improves the heat exchange efficiency of the flat tube when in use.

And the outer ring teeth of the first synchronous gear 1302 and the second synchronous gear 1303 on the upper and lower sides are relatively long, and the misalignment distance of meshing with each other is greater than the maximum sliding distance of the sliding cushion block 2102 moving up and down, so that the first synchronous gear 1302 and the second synchronous gear 1303 on the upper and lower sides will not be displaced when the sliding cushion block 2102 slides up and down, ensuring that the bump rollers 1202 and the concave dot rollers 1204 on the upper and lower sides of the device can maintain synchronous reverse rotation when in use, and the concave dot roller 1204 will not stop due to moving up and down.

[0039] Embodiment 2

[0040] Refer to Figures 1 to 5 and Figures 7 to 9 and, on the basis of Embodiment 1, it is further obtained that the adjusting mechanism 2 includes a support assembly 21, an adjusting assembly 22, a second driving assembly 23 and a reciprocating assembly 24. The support assembly 21 is arranged inside the front and rear sides of the vertical frame 41, the adjusting assembly 22 is arranged inside the top of the support assembly 21, the second driving assembly 23 is arranged inside the top of the rear side of the base frame 3, and the reciprocating assembly 24 is arranged inside the top of the vertical frame 41 of the second driving assembly 23.

[0041] The support assembly 21 includes a fixed cushion block 2101 which is fixedly connected to the inner bottom of the front and rear sides of the vertical frame 41. The fixed cushion block 2101 is rotatably connected to the outer ring of the first rotating shaft 1201. Above the fixed cushion block 2101, there is a sliding cushion block 2102 which is slidably connected to the inner sides of the front and rear sides of the vertical frame 41. The sliding cushion block 2102 is rotatably connected to the outer ring of the second rotating shaft 1203. A spring 2103 is arranged between the fixed cushion block 2101 and the sliding cushion block 2102. The outer side of the sliding cushion block 2102 is fixedly connected with a roller guide rail 2104 which is slidably connected to the inner sides of the left and right sides of the base 4. The adjusting assembly 22 includes a depth adjusting cushion block 2201 which is clamped inside the top of the sliding cushion block 2102. On the top of the depth adjusting cushion block 2201, there is a fixed block 2202 which is clamped inside the top of the sliding cushion block 2102. A bolt 2203 is sleeved inside the outer side of the fixed block 2202 and is threadedly connected to the inner top of the sliding cushion block 2102. The second driving assembly 23 includes a fixed frame 2301 which is fixedly connected to the inner top of the rear side of the base frame 3. A second driving motor 2302 is fixedly connected to the rear side of the fixed frame 2301. A second driving shaft 2303 is fixedly connected to the front side of the second driving motor 2302. A connecting shaft body 2304 is fixedly connected to the front side of the second driving shaft 2303 and is rotatably connected to the inner top of the front side of the base frame 3. The reciprocating assembly 24 includes a first rotating shaft 2401 which is fixedly connected to the front side of the connecting shaft body 2304 and is rotatably connected to the inner top of the vertical frame 41. An outer ring of the first rotating shaft 2401 is fixedly connected with a reciprocating cam 2402. The bottom of the outer ring of the reciprocating cam 2402 is drivingly connected with a cam follower 2403. The inner ring of the cam follower 2403 is rotatably connected with a rotating wheel 2404. An outer side of the rotating wheel 2404 is fixedly connected with a second rotating shaft 2405 which is rotatably connected to the inner top of the vertical frame 41.

[0042] Furthermore: The staff only needs to start the second driving motor 2302 to drive the reciprocating cam 2402 to rotate. Through the different diameters of the outer ring of the reciprocating cam 2402, the cam follower 2403 is driven to move up and down reciprocally, driving the upper concave point roller 1204 to press downward to complete the pressing process of the convex points on the surface of the flat tube. At the same time, the staff only needs to change the rotation speed of the second driving motor 2302 to change the interval distance of the convex points during the pressing of the flat tube, which is convenient for the staff to use. At the same time, the staff can change the distance of the upper sliding cushion block 2102 during downward pressing by increasing or decreasing the number of depth adjusting cushion blocks 2201, so that the staff can adjust the depth of the convex points after pressing according to needs, making the device adaptable to flat tubes of different thicknesses during use, increasing the applicable range of the device and being convenient for the staff to use.

[0043] During the actual operation process, when this device is in use and it is necessary to perform bump pressing on the flat tube, the staff first starts the first driving motor 1101. When the first driving motor 1101 starts, it drives the driving gear 1103 to rotate through the first driving shaft 1102. The rotation of the driving gear 1103 drives the first rotating shaft 1201 to rotate through the transmission gear 1301. When the first rotating shaft 1201 rotates to drive the bump roller 1202 to rotate, it also drives the second rotating shaft 1203 to perform reverse synchronous rotation through the first synchronous gear 1302 and the second synchronous gear 1303. The rotation of the second rotating shaft 1203 drives the concave point roller 1204 to rotate. At this time, the upper and lower bump rollers 1202 and the concave point rollers 1204 rotate in reverse synchronously to convey the passing flat tube, so that the flat tube can pass between the bump roller 1202 and the concave point roller 1204, completing the automatic feeding of the flat tube;

[0044] After that, the staff then starts the second driving motor 2302. When the second driving motor 2302 starts, it drives the connecting shaft body 2304 to rotate through the second driving shaft 2303. The rotation of the connecting shaft body 2304 drives the reciprocating cam 2402 to rotate through the first rotating shaft 2401. The rotation of the reciprocating cam 2402 squeezes the fixed block 2202 to move downward through the cam follower 2403 and the rotating wheel 2404. The downward movement of the fixed block 2202 drives the sliding cushion block 2102 to move downward. The downward movement of the sliding cushion block 2102 drives the concave point roller 1204 to move downward through the second rotating shaft 1203. While the concave point roller 1204 moves downward, it keeps rotating and cooperates with the bump roller 1202 to squeeze the flat tube below to form a concave point. After that, the reciprocating cam 2402 continues to rotate to release the downward pressure on the cam follower 2403, and then the sliding cushion block 2102 will move upward by itself under the action of the seat spring 2103, so that the cam follower 2403 can keep in contact with the bottom of the reciprocating cam 2402. Repeating this process completes the processing of the flat tube.
