The straightening roller 67 and the end of the swing arm 68 away from the sleeve 66 are connected.

[0033] Reference Figure 8As shown, a straightening support roller assembly 7 is provided on the straightening machine 1, and the straightening support roller assembly 7 includes a U-shaped support frame 71, a lifting drive cylinder 72, a bottom support roller 73 and a right-angle support frame 74. The U-shaped support frame 71 is fixedly installed on the straightening machine 1, and the lifting drive cylinder 72 is installed on the U-shaped support frame 71. The right-angle support frame 74 is connected to the output end of the lifting drive cylinder 72. Two bottom support rollers 73 are provided on the right-angle support frame 74, and the bottom support rollers 73 are located below the straightening roller 67.

[0035] Reference Figure 5-7 As shown, the traction device 2 includes a traction drive motor 21, a traction driving wheel 22, a traction driven wheel 23, a gear belt 24 and two groups of traction roller assemblies 25. The traction drive motor 21 is connected to the traction driving wheel 22. The gear belt 24 is sleeved on the traction driving wheel 22 and the traction driven wheel 23. The traction driving wheel 22 is connected to the traction roller assembly 25 through the gear belt 24. The traction driving wheel 22 and the traction driven wheel 23 are respectively located on both sides of the straightening machine 1, and the gear belt 24 is stretched. The two groups of traction roller assemblies 25 are located between the traction driving wheel 22 and the traction driven wheel 23, and the traction roller assembly 25, the traction driving wheel 22 and the traction driven wheel 23 are connected through the gear belt 24.

[0036] In the above structure, the traction roller assembly 25 includes a support frame 251, a plurality of traction rollers 252, a clamping drive cylinder 253 and a longitudinal clamping roller 254. The traction roller 252 is arranged on the support frame 251 through a rotating shaft, and a driving gear 255 is connected to the rotating shaft of the traction roller 252. The gear belt 24 is meshed with the driving gear 255. The clamping drive cylinder 253 is installed on the top of the support frame 251, and the output end of the clamping drive cylinder 253 is connected to the longitudinal clamping roller 254. The profile passes between the longitudinal clamping roller 254 and the traction roller 252. Preferably, the number of the traction rollers 252 is two. Initially, the piston rod of the clamping drive cylinder 253 is in a retracted state, so a large gap is left between the longitudinal clamping roller 254 and the traction roller 252. When the profile passes between the longitudinal clamping roller 254 and the traction roller 252, the piston rod of the clamping drive cylinder 253 extends out, pushing the longitudinal clamping roller 254 to contact the upper end surface of the profile, thereby limiting the upper end surface of the profile to prevent the two ends of the profile from warping during the straightening process.

[0037] In the above structure, the output end of the clamping driving cylinder 253 is connected to a clamping roller mounting frame 256, and the longitudinal clamping roller 254 is arranged on the clamping roller mounting frame 256. The clamping roller mounting frame 256 is connected to a guide column 257, and a guide sleeve 258 is arranged on the support frame 1 251. The guide column 257 penetrates the guide sleeve 258, and the guide column 257 can slide along the guide sleeve 258.

[0038] In the above structure, the support frame 1 251 is provided with a belt guide wheel 259, and the gear belt 24 is wound around the outer wall of the belt guide wheel 259. The gear belt 24 is wound around the belt guide wheel 259, and the belt guide wheel 259 can be used to tension and guide the gear belt 24.

[0039] Reference Figure 5-7As shown, the horizontal adjustment device 3 includes a hand wheel 31, an adjustment gear 1 32, an adjustment gear 2 33 and an adjustment screw 34. The hand wheel 31 is connected to the adjustment gear 1 32, the adjustment gear 1 32 is connected to the adjustment gear 2 33 through a chain, the adjustment gear 2 33 is connected to one end of the adjustment screw 34, the adjustment screw 34 is arranged on the straightening machine 1, and the two groups of ejection devices 4 are connected to the adjustment screw 34. The two ends of the adjustment screw 34 in the axial direction are respectively provided with a forward thread and a reverse thread, and the two groups of ejection devices 4 are respectively connected to the forward thread and the reverse thread. When the hand wheel 31 rotates the adjustment gear 1 32, the adjustment gear 1 32 drives the adjustment gear 2 33 to rotate through the chain, so that the adjustment screw 34 rotates. Since the adjustment screw 34 is provided with forward and reverse threads, the two groups of ejection devices 4 can move in opposite directions or in opposite directions along the forward thread and the reverse thread, so as to adjust the distance between the two groups of ejection devices 4 to adapt to different profiles. The two groups of traction roller assemblies 25 and the two groups of push-up devices 4 are arranged in a one-to-one correspondence, and the support frame 1 251 is installed on the corresponding push-up device 4.

[0040] Reference Fig. 9 , 10As shown, the ejection device 4 includes an ejection support seat 41, an ejection drive cylinder 42, a transverse pressing roller 43 and an ejection block 44. The ejection support seat 41 is connected to the adjustment screw 34. The ejection drive cylinder 42 and the ejection block 44 are both arranged on the ejection support seat 41. The transverse pressing roller 43 is connected to the output end of the ejection drive cylinder 42, and the ejection drive cylinder 42 drives the transverse pressing roller 43 to press the side wall of the profile onto the ejection block 44. The longitudinal pressing roller 254 presses down the upper end surface of the profile from above the profile under the push of the pressing drive cylinder 253. The ejection block 44 and the transverse pressing roller 43 are in contact with the vertical side walls on both sides of the profile respectively. The transverse pressing roller 43 and the straightening roller 67 are located on the same side to press one side of the profile, and the ejection block 44 presses the other side of the profile. The end face of the ejection block 44 in contact with the profile is set as an arc-shaped surface 441, and the arc-shaped surface 441 is convex in the middle and transitions to an arc shape on both sides, and the convex direction of the arc-shaped surface 441 is toward the side wall of the profile. In this way, during the straightening process of the profile, the profile contacts the arc-shaped surface 441 through the straightening roller 67 sliding on the side wall of the profile and pushing and straightening. It can avoid damage to the profile and match the straightening angle of the profile when the profile is straightened. Initially, the piston rod of the push-pushing driving cylinder 42 extends, so that there is a large gap between the transverse pressing roller 43 and the push-pushing block 44. When the transverse pressing roller 43 and the push-pushing block 44 pass through the profile, the piston rod of the push-pushing driving cylinder 42 is retracted, driving the transverse pressing roller 43 to move toward the push-pushing block 44, thereby limiting the profile between the transverse pressing roller 43 and the push-pushing block 44 for the straightening roller 67 to straighten the profile. The two transverse pressing rollers 43 are located on both sides of the straightening roller 67, and the push-pushing block 44 is also located on both sides of the straightening roller 67. The transverse pressing roller 43 limits the straightening ends of the profile to avoid bending and deformation of the two ends of the profile during the straightening of the profile by the straightening roller 67. The two bottom support rollers 73, the transverse pressing roller 43, the longitudinal pressing roller 254 and the push-pushing block 44 are respectively set with limits on the four sides of the rectangular profile, so as to help the straightening roller 67 to straighten the profile.

[0042] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
