[0030] Example

[0031] Reference Figure 1-5 A high-efficiency straightening machine for processing aluminum flat tubes includes a first support base 1, a first adjusting combination plate 7, and a second adjusting combination plate 8. The first support base 1 is vertically fixedly mounted with a first straightening mechanism, and one end of the first support base 1 is horizontally fixedly mounted with a second straightening mechanism so that the aluminum flat tube can pass between the first straightening mechanism and the second straightening mechanism and be straightened.

[0032] In this embodiment, the first straightening mechanism includes a support plate 2, straightening rollers 3, traction rollers 4, and a transmission gear set 13. Several straightening rollers 3 and two traction rollers 4 are evenly rotatably mounted on one side of the support plate 2 so as to support the straightening rollers 3 and traction rollers 4 through the support plate 2. Several straightening rollers 3 form a straightening roller group. At least five straightening rollers 3 are provided and are evenly arranged in a five-point shape. The two traction rollers 4 are on the side away from the second straightening mechanism so as to pull the aluminum flat tube through the straightening roller group. The transmission gear set 13 is fixedly mounted on the other side of the support plate 2 so as to connect with an external power mechanism through the transmission gear set 13. The external drive mechanism drives the traction rollers 4 to rotate. One gear of the transmission gear set 13 is fixedly connected to one end of one of the traction rollers 4.

[0033] In this embodiment, the straightening roller group composed of straightening rollers 3 is rotatably connected to the first adjusting combination plate 7 so that the straightening rollers 3 can rotate smoothly, and the first adjusting combination plate 7 is slidably connected to the first support base 1.

[0034] In this embodiment, the two traction rollers 4 are rotatably connected to the second adjustment combination plate 8 so that the traction rollers 4 can rotate smoothly. The second adjustment combination plate 8 is fixedly connected to the first adjustment combination plate 7 so that the second adjustment combination plate 8 moves synchronously with the first adjustment combination plate 7.

[0035] In this embodiment, the second straightening mechanism differs from the first straightening mechanism only in that: the second straightening mechanism does not install the traction roller 4, the transmission gear set 13 and the second adjustment combination plate 8, and the second straightening mechanism replaces the support plate 2 with the L support plate 12. The first adjustment combination plate 7 on the second straightening mechanism is slidably connected to the L support plate 12.

[0036] In this embodiment, the straightening roller 3 has the same composition and structure as the traction roller 4.

[0037] In this embodiment, the straightening roller 3 includes a fixed roller 31, a moving roller 32, and an anti-detachment ring 33. One end of the fixed roller 31 is slidably connected to one end of the moving roller 32, and the other end of the moving roller 32 is coaxially provided with an anti-detachment ring 33. A through hole 34 is coaxially opened between the fixed roller 31, the moving roller 32, and the anti-detachment ring 33. The diameter of the moving roller 32 is smaller than the diameter of the fixed roller 31 and the anti-detachment ring 33, and the diameter of the fixed roller 31 is the same as the diameter of the anti-detachment ring 33, so that a ring cavity for limiting the aluminum flat tube is formed between the fixed roller 31, the moving roller 32, and the anti-detachment ring 33. The anti-detachment ring 33 is rotatably connected to the first adjusting combination plate 7, so that the distance between the anti-detachment ring 33 and the fixed roller 31 can be adjusted under the drive of the first adjusting combination plate 7, thereby adjusting the size of the ring cavity and realizing the straightening effect of aluminum flat tubes of various specifications. The fixed roller 31, the moving roller 32, and the anti-detachment ring 33 are rotatably mounted on the corresponding support plate 2 and L support plate 12.

[0038] In this embodiment, a ring cavity 35 is provided at one end of the fixed roller 31 to provide sliding space for the moving roller 32. A constriction 36 is provided in the opening of the ring cavity 35. The constriction 36 can prevent accidental separation between the moving roller 32 and the fixed roller 31. The inner diameter of the constriction 36 is smaller than the inner diameter of the ring cavity 35. A support shaft 37 is formed between the ring cavity 35 and the fixed roller 31 to support the moving roller 32. Several sliding grooves 38 are evenly provided on the outer circumferential surface of the support shaft 37 to limit the movement of the moving roller 32 and prevent the moving roller 32 from rotating. One end of the moving roller 32 is slidably sleeved on the support shaft 37 through the ring cavity 35, and the moving roller 32 is slidably connected to the sliding grooves 38.

[0039] In this embodiment, an anti-detachment edge 39 is coaxially provided at one end of the moving roller 32 connected to the fixed roller 31. The anti-detachment edge 39 is slidably installed in the annular cavity 35. The diameter of the anti-detachment edge 39 is larger than the inner diameter of the constriction 36 to prevent the moving roller 32 from separating from the fixed roller 31. A number of sliders 30 corresponding to the slide grooves 38 are provided on the inner surface of the moving roller 32. The sliders 30 are slidably installed in the corresponding slide grooves 38 to limit the moving roller 32 so that the moving roller 32 can only rotate with the fixed roller 31.

[0040] In this embodiment, the first adjusting combination plate 7 includes a fixed plate 71, a first movable plate 72, a second movable plate 73, a connecting column 77, an electric push rod 9, a fixed base 10, and a slide rail 11. The two sides above the fixed plate 71 are slidably connected to the first movable plate 72 and the second movable plate 73 through the connecting column 77, so as to adjust the straightening roller 3 on which the adjuster is installed individually. The fixed plate 71, the first movable plate 72, and the second movable plate 73 are each provided with a shaft hole 74 corresponding to the straightening roller 3. A rotating drum 75 is coaxially rotatably installed at one end of each shaft hole 74. The other end of the rotating drum 75 is coaxially fixedly connected to the corresponding anti-detachment ring 33, so that the size of each straightening roller 3 can be adjusted simultaneously by the first adjusting combination plate 7 without affecting the normal rotation of the straightening roller 3. U-shaped support legs 76 are uniformly fixedly installed below the fixed plate 71. The opening of the leg 76 is slidably connected to the corresponding slide rail 11. The slide rail 11 is fixedly installed on the first support base 1 so that the first adjustment combination plate 7 can be supported by the U-shaped support leg 76, so as to avoid the weight of the first adjustment combination plate 7 directly acting on the electric push rod 9, and at the same time, it can ensure the stability and smoothness of the first adjustment combination plate 7 during movement. The electric push rod 9 is fixedly installed horizontally on the first support base 1 through the fixed base 10. The output end of the electric push rod 9 is fixedly connected to the fixed plate 71 so that each moving roller 32 can be pulled simultaneously by the electric push rod 9 to adjust the distance between the moving roller 32 and the fixed roller 31, so as to straighten aluminum flat tubes of various specifications. The electric push rod 9 is vertically arranged with the fixed plate 71, and horizontally arranged with the straightening roller 3. The fixed plate 71 is fixedly connected to the second adjustment combination plate 8.

[0041] In this embodiment, the second adjustment combination plate 8 includes a second fixed plate 81, a third movable plate 82, and a second rotating drum 84. The third movable plate 82 is horizontally slidably mounted on the second fixed plate 81 via a connecting column 77, so as to allow for individual adjustment of the traction roller 4 on which the adjuster is mounted. The second fixed plate 81 and the third movable plate 82 each have a through shaft hole 83. One end of the shaft hole 83 is coaxially rotatably mounted on the second rotating drum 84. The other end of the second rotating drum 84 is fixedly connected to one end of the corresponding traction roller 4. One end of the second fixed plate 81 is fixedly connected to the fixed plate 71, so that the second adjustment combination plate 8 moves simultaneously with the first adjustment combination plate 7. The second fixed plate 81 is slidably connected to the first support base 1.

[0042] In this embodiment, each of the two straightening rollers 3 connected to the first movable plate 72 and the second movable plate 73, and the traction roller 4 connected to the third movable plate 82, is provided with an adjuster. The adjuster includes an adjusting block 5 and an adjusting rod 6. The adjusting block 5 is rotatably connected to one end of the adjusting rod 6. The adjusting block 5 is slidably mounted on the corresponding support plate 2 and the L support plate 12. The adjusting rod 6 is rotatably mounted on the corresponding support plate 2 and the L support plate 12 by means of a thread. The adjusting block 5 is rotatably connected to one end of the corresponding fixed roller 31, so that the adjusting block 5 can be driven to move the corresponding straightening roller 3 by rotating the adjusting rod 6.

[0043] In this embodiment, a power shaft 14 is fixedly mounted on one of the gears of the transmission gear set 13 so as to connect to the output end of an external power mechanism through the power shaft 14.

[0044] It should be noted that the electric actuator 9 is controlled by an external controller, such as a PLC controller or a microcontroller.

[0045] In practical use, when it is necessary to straighten aluminum flat tubes of different specifications, simply retract the electric push rod 9 to pull the fixed plate 71, which in turn drives the second fixed plate 81. At this time, the straightening roller 3 and the traction roller 4 will unfold until they are unfolded to the required length.

[0046] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
