The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0041] like Figure 1 and Figure 2As shown, an aluminum profile traction machine according to one embodiment of the present invention includes a guide rail component 1, an upper traction machine 2, and a lower traction machine 3; the guide rail component 1 includes an upper guide rail assembly 11 and a lower guide rail assembly 12, the upper traction machine 2 is disposed on the upper guide rail assembly 11, and the lower traction machine 3 is disposed on the lower guide rail assembly 12; the upper traction machine 2 includes an upper frame component 21 and a first jaw device 22 disposed on the upper frame component 21, the first jaw device 22 includes a first clamping plate 221, a first servo motor 222, and a device driven by the first servo motor 222. The first clamping block 223 is movable, and a first clamping space is formed between the first clamping plate 221 and the first clamping block 223; the lower traction machine 3 includes a lower frame component 31 and a second jaw device 32 disposed on the lower frame component 31. The second jaw device 32 includes a second clamping plate 321, a second servo motor 322 and a second clamping block 323 driven by the second servo motor 322. A second clamping space is formed between the second clamping plate 321 and the second clamping block 323; the upper traction machine 2 and the lower traction machine 3 perform traction work alternately.

[0042] The aforementioned aluminum profile traction machine uses a first servo motor 222 to drive a first clamping block 223 to rotate relative to a first clamping plate 221, thereby clamping the aluminum profile. This allows the operator to control the rotation size and torque of the first servo motor 222 according to the cross-sectional dimensions of the aluminum profile, thus controlling the clamping force and preventing the aluminum profile from breaking at the clamping position. At the same time, by setting up an upper traction machine 2 and a lower traction machine 3 to use a relay method for traction, production efficiency is improved.

[0043] like Figure 3 As shown, in one embodiment, the traction machine further includes a marking and detection device 4 mounted on the upper frame component 21. The marking and detection device 4 includes a laser marking component 41 and a detection component 42. The laser marking component 41 is used to laser-mark the aluminum profile before clamping; the detection component 42 is used to detect the position of the marking on the aluminum profile. Thus, by laser-marking the aluminum profile before clamping with the laser marking component 41, and then monitoring the marking position with the detection component 42, the length of the aluminum profile being stretched can be determined by monitoring the position change of the marking position, thereby preventing the aluminum profile from breaking during the traction process.

[0044] In one specific embodiment, the detection component 42 includes a detection camera and a recognition system. The detection camera captures an image of the laser marking location and sends it to the recognition system. The recognition system determines the positional change of the marking location and sends a signal to the electronic control component 5 to control the first servo motor 222.

[0045] In one embodiment, a laser marking device and a position detection sensor are provided at the extrusion exit of the extrusion die. The position detection sensor detects the distance between the aluminum profile head and the marking mark and sends a position signal to the laser marking device, which then marks the aluminum profile at the designated position. This avoids the marking position being clamped by the jaws of the traction machine, thus preventing it from serving its marking purpose.

[0046] In one embodiment, the laser marking component 41 and the detection component 42 are sequentially arranged on the side of the extrusion machine closer to the extrusion outlet relative to the first clamping space. Thus, because the upper traction machine 2 is subjected to outward traction, the aluminum profile is typically stretched during the traction process on the side of the extrusion machine closer to the extrusion outlet relative to the first clamping space, facilitating the detection component 42 to detect the laser marking position.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment, the upper frame component 21 includes a first moving assembly 211, a second moving assembly 212, and a third moving assembly 213. The first moving assembly 211 includes a first frame 2111 movable on the upper guide rail assembly 11. The second moving assembly 212 includes a second frame 2121 movable on the first frame 2111 and a second drive group 2122 for driving the second frame 2121. The third moving assembly 213 includes a third frame 2131 movable on the second frame 2121 and a third drive group 2132 for driving the third frame 2131. Specifically, the first jaw device 22 is fixedly mounted on the third frame 2131. Thus, by using the second drive group 2122 and the third drive group 2132 to control the second frame 2121 and the third frame 2131 respectively, the first jaw device 22 can avoid repeated relay traction actions by the lower traction machine 3.

[0048] In one embodiment, the first frame 2111 moves along the X direction on the upper guide rail assembly 11; the second frame 2121 moves along the Y direction on the first frame 2111; and the third frame 2131 moves along the Z direction on the second frame 2121. This allows the first jaw device 22 to move in the X, Y, and Z directions, facilitating its avoidance of repeated relay traction actions by the lower traction machine 3.

[0049] In one embodiment, the first moving component 211 includes a first drive motor 2112 mounted on a first frame 2111 and a first gear 2113 driven by the first drive motor 2112; the upper guide rail assembly 11 is provided with a transmission rack 111 adapted to the first gear 2113. Thus, the first gear 2113 driven by the first drive motor 2112 rotates, and the first gear 2113 meshes with the transmission rack 111, providing a good guiding transmission function; in addition, the meshing transmission of the first gear 2113 and the transmission rack 111 ensures the moving accuracy of the upper traction machine 2.

[0050] like Figure 5 As shown, in one embodiment, the first moving component 211 includes a pulley assembly 2114 disposed on the first frame 2111; the upper guide rail assembly 11 includes a track bar; the pulley assembly 2114 includes guide wheel units 2115 for clamping the upper and lower sides of the track bar and limiting wheels 2116 positioned on the outer side of the track bar. Specifically, the first frame 2111 is a rectangular frame, and the pulley assembly 2114 is disposed at the four right angles of the rectangular frame. Thus, the guide wheel units 2115 limit the first frame 2111 to the vertical movement surface of the upper guide rail assembly 11, and the limiting wheels 2116 on both sides prevent the first frame 2111 from swaying left and right during movement, ensuring the accuracy of traction movement.

[0051] In one embodiment, the first moving component 211 further includes a first stroke detection group for detecting the stroke of the first frame 2111; the first stroke detection group includes an absolute rotary encoder that is drivenly connected to the output shaft of the first drive motor 2112. Thus, by using the absolute rotary encoder to record the rotational speed and number of rotations of the first drive motor 2112, the movement stroke of the first frame 2111 is fed back, thereby facilitating the assurance of traction movement accuracy.

[0052] like Figure 3 As shown, in one embodiment, a pressure sensor 51 is provided on the clamping surface of the first clamping plate 221 relative to the first clamping block 223. The pressure sensor 51 is used to detect the pressure applied by the first clamping block 223 to the aluminum profile. Thus, by detecting the pressure applied by the pressure sensor 51 to the aluminum profile and sending a signal to provide feedback on the pressure, the rotational torque of the first servo motor 222 is controlled, thereby controlling the clamping force and preventing the aluminum profile from breaking at the clamping position.

[0053] In one embodiment, the traction machine further includes an electronic control unit 5, which is electrically connected to the second drive group 2122, the third drive group 2132, and the pressure sensor 51. Thus, by uniformly controlling the second drive group 2122, the third drive group 2132, and the pressure sensor 51 through the electronic control unit 5, the aluminum profile traction machine can easily complete the automated production process.

[0054] Specifically, the aluminum profile traction machine is used in the alternating traction system of the aluminum extrusion equipment. After the aluminum profile is extruded by the extruder, the aluminum profile traction machine is used to fix the end of the aluminum profile and guide its direction. The detailed working steps are as follows:

[0055] S1. Traction process of upper traction machine 2: The first servo motor 222 drives the first clamping block 223 to cooperate with the first clamping plate 221 to clamp the aluminum profile. Then, the first drive motor 2112 drives the first frame 2111 to slide on the upper guide rail assembly 11 to pull the aluminum profile. When it reaches the designated position, the lower traction machine starts to work.

[0056] S2. Traction process of lower tractor 3: Same as traction process of upper tractor 2;

[0057] S3. Traction and return process of upper traction machine 2: The first drive motor 2112 on the first frame 2111 moves in the opposite direction to return to its original position. In order to avoid collision with lower traction machine 3 during the movement, the second drive group 2122 drives the second frame 2121 to move along the Y direction, and the third drive group 2132 drives the third frame 2131 to move along the Z direction, so that the upper traction machine 2 avoids the lower traction machine 3 and returns to its original position.

[0058] S4. After the current traction machine 3 pulls the aluminum profile into place, the upper traction machine 2 performs the action of step S1.

[0059] S5. Lower traction machine returns to position: Refer to step S3;

[0060] S6. Repeat steps S1 to S5.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
