[0002] A bamboo ladder is a portable ladder with a telescopic structure. It is named for its resemblance to interlocking bamboo sections when unfolded. Its main body is mostly made of high-strength aluminum alloy profiles, combining lightweight design with load-bearing capacity.

[0003] Currently, the production of bamboo-joint ladders also involves the production of aluminum profiles. During the rolling process, aluminum profiles will bend and twist due to uneven stress. Therefore, after the aluminum profiles are rolled, they need to be straightened by applying mechanical external force to forcefully correct their shape.

[0004] However, existing aluminum profile straightening processes require operators to manually adjust and control the stretching force and stroke, which is not only labor-intensive and inefficient, but also results in poor straightening performance based solely on experience, thus affecting the use of the bamboo-joint ladders manufactured subsequently. This paper proposes an aluminum profile straightening device for bamboo-joint ladder production to improve the existing problems. Utility Model Content

[0028] Please see Figures 1-4 The present invention provides the following technical solution:

[0031] See Figure 2 The second jaw assembly 4 includes a second upper jaw tooth 43, and a second lower jaw plate 44 is provided below the second upper jaw tooth 43.

[0032] Both the first upper clamping tooth 13 and the second upper clamping tooth 43 are composed of multiple sets of clamping plates. The multiple sets of clamping plates can increase the friction on the aluminum profile, providing a basis for the normal operation of the subsequent straightening work. At the same time, the upper surfaces of the first lower clamping platform 14 and the second lower clamping platform 44 are provided with protrusions. The protrusion of the first lower clamping platform 14 is adapted to the gap formed by the clamping plates of the first upper clamping tooth 13, and the protrusion of the second lower clamping platform 44 is adapted to the gap formed by the clamping plates of the second upper clamping tooth 43. The cooperation of the two can realize the limiting and fixing of the aluminum profile, which facilitates the normal operation of the straightening work.

[0033] See Figure 2 The first jaw assembly 1 also includes a first mounting bracket 11. A first clamping cylinder 12 is disposed above the first mounting bracket 11. A first hinge seat is disposed between the first clamping cylinder 12 and the first mounting bracket 11. The first clamping cylinder 12 is hinged to the first hinge seat, and the first hinge seat is fixedly connected to the first mounting bracket 11.

[0034] See Figure 2 The first upper jaw 13 is connected to the output end of the first clamping cylinder 12.

One end of the fixed frame is connected to the first clamping cylinder 12, and the other end of the fixed frame is connected to the first upper clamping tooth 13. The first clamping cylinder 12 can drive the first upper clamping tooth 13 to swing. That is, when the first clamping cylinder 12 retracts, the first upper clamping tooth 13 lifts up, and when the first clamping cylinder 12 extends, the first upper clamping tooth 13 presses down. Under the drive of the first clamping cylinder 12, the aluminum profile can be limited.

The tensioning mechanism 24 is a combined tensioning device, which includes a first tensioning cylinder, a connecting rod, and a sliding seat. The output end of the first tensioning cylinder is connected to the sliding seat. A third pulley group is slidably connected between the sliding seat and the first slide rail 22. One end of the connecting rod is connected to the first sliding frame 21, and the other end is connected to the sliding seat.

[0038] The first pulley assembly 23 is slidably connected to the outer wall of the first sliding frame 21. The inner wall of the first slide rail 22 is provided with a first guide rail groove and a second guide rail groove. The first guide rail groove is higher than the second guide rail groove. The first pulley assembly 23 is set inside the first guide rail groove. The second guide rail groove is provided with a mounting plate. A mounting bracket is provided between the first tension cylinder and the mounting plate. The first tension cylinder is installed through the mounting bracket. Several support plates are also provided below the second guide rail groove of the first slide rail 22. The support plates are used to support the entire device.

[0039] During the actual stretching process, the first stretching cylinder is activated, which drives the sliding seat to move horizontally along the first slide rail 22. Since the sliding seat and the first sliding frame 21 are connected by a connecting rod, the first sliding frame 21 moves horizontally under the drive of the sliding seat, and then the first mounting frame 11 moves with it, realizing the horizontal movement of the first mounting frame 11, which provides a foundation for the subsequent stretching of the aluminum profile.

[0040] See Figure 2 and Figure 3 The second sliding assembly 3 includes a second slide rail 31, a second mounting bracket 32 ​​is provided at the middle position of the second slide rail 31, a second tension cylinder 33 is provided on one side of the second mounting bracket 32, a second hinge seat is provided at the middle position of the second tension cylinder 33 and the second mounting bracket 32, the second hinge seat is hinged to the second tension cylinder 33, the second hinge seat is fixedly connected to the second mounting bracket 32, and the output end of the second tension cylinder 33 is connected to the second slide rail 31 through a hinge rod.

[0041] The second slide rail 31 has a support rod at the middle position, and a fourth hinge seat is provided at the middle position between the hinge rod and the support rod. The fourth hinge seat is fixedly connected to the support rod and is hinged to the hinge rod.

The two sides of the second upper clamping teeth 43 are rotatably connected to the second sliding frame 41 respectively. The two sides of the second lower clamping platform 44 are fixedly connected to the second sliding frame 41. The second pulley group 45 is disposed on the outer side of the second sliding frame 41.

[0044] The second pulley block 45 is slidably connected to the second slide rail 31. The second tension cylinder 33 is activated, and the second tension cylinder 33 drives the hinge rod to move. Under the drive of the hinge rod, the support rod drives the second sliding frame 41 to move along the second slide rail 31 through the second pulley block 45, realizing the overall movement and facilitating the normal progress of subsequent straightening work.

[0045] Specifically, firstly, the first clamping cylinder 12 and the second clamping cylinder 42 are activated respectively. The first upper clamping teeth 13 and the second upper clamping teeth 43 are lifted under the action of the first clamping cylinder 12. At this time, the aluminum profile is placed above the first lower clamping platform 14 and the second lower clamping platform 44. Then, the first clamping cylinder 12 and the second clamping cylinder 42 are activated in the opposite direction. The first upper clamping teeth 13 and the second upper clamping teeth 43 are pressed down onto the surface of the aluminum profile to achieve the limiting clamping of the aluminum profile. Then, the second stretching cylinder 33 and the stretching mechanism 24 are activated respectively. Under the action of the second stretching cylinder 33 and the stretching mechanism 24, the second sliding frame 41 and the first sliding frame 21 stretch the aluminum profile in opposite directions to straighten the aluminum profile.
