Description

Technical Field

[0001] This utility model relates to the field of aluminum profile traction technology, and in particular to a traction device for aluminum profile production. Background Technology

[0002] Aluminum profiles are long and strip-shaped structures, and are mainly produced by extrusion molding. Because they are produced by melting at high temperatures and then forming, operators need to actively pull the flat aluminum profiles out of the production equipment or pull them out using a traction device during the extrusion and transportation on the production line.

[0003] A search revealed a traction device for aluminum profile production (publication number CN217831293U). The device includes a first electric push rod positioned between the traction table and a support base. A second groove is formed through the middle of the lower surface of the support base, and multiple pressure rollers are arranged inside the second groove. A second motor is mounted on the front end of the support base. During operation, the first electric push rod can be extended or retracted according to the size of the aluminum profile to be traction and transported. This allows the pressure rollers and traction rollers to clamp the aluminum profile from both ends. The rotation of the first motor causes the traction rollers to rotate, and the rotation of the second motor causes the pressure rollers to rotate, thus achieving the traction and transport of the aluminum profile. The coordinated operation of multiple traction rollers and pressure rollers enables continuous traction and transport of the aluminum profile, improving its efficiency.

[0004] In the aforementioned existing technical solutions, the traction roller and pressure roller clamp the upper and lower ends of the aluminum profile in the traction device to achieve transmission. However, if the clamping force is too large or improperly adjusted, it may cause indentation or deformation of the aluminum profile, affecting the quality of the product.

[0005] Therefore, we propose a traction device for aluminum profile production. Utility Model Content

[0015] 2. This traction device for aluminum profile production, through the cooperation of a limiting rod, a limiting block and a spring, makes the limiting plate more stable during displacement, thereby improving the stability of the device.

The top of the limiting rods 401 is fixedly connected to the wall of the inner cavity of the mounting bracket 3. A spring 402 is sleeved on the limiting rods 401 above the limiting plate 4. Limiting blocks 403 are fixedly connected to the limiting rods 401 below the limiting plate 4. A buffer sleeve 7 is fixedly connected to the center of the bottom of the limiting plate 4. A buffer sleeve 6 is sleeved in the inner cavity of the bottom of the buffer sleeve 7. A connecting rod is fixedly connected to the bottom of the buffer sleeve 6. Connecting frame 5, the inner cavity of connecting frame 5 is rotatably connected to conveyor roller 2 501, the outer walls of conveyor roller 2 501 and multiple conveyor rollers 1 2 are all fixedly connected with rubber sleeves 201 by adhesive, the inner cavity of buffer sleeve 6 has limit grooves 601 on both side walls, the bottom of buffer sleeve rod 7 is fixedly connected to limit sliders 703 on both sides corresponding to the limit grooves 601, the limit sliders 703 are adapted to the limit grooves 601 and the limit sliders 703 are limited in the limit position.

[0027] The working principle of this utility model:

[0028] In use, the aluminum profile is placed above the first conveyor roller 2 on the base 1. The hydraulic cylinder 301 is activated to drive the connecting frame 5 at the bottom of the limit plate 4 to approach the aluminum profile. The second conveyor roller 501 on the connecting frame 5 clamps the aluminum profile. When the hydraulic cylinder 301 presses the second conveyor roller 501, the buffer sleeve 6 moves closer to the buffer slider 701. At this time, the third spring 8 in the inner cavity of the buffer sleeve 6 initially buffers the clamping force of the second conveyor roller 501. The buffer sleeve 6 moves closer to the buffer slider 701 and, under the action of the second spring 702, buffers the clamping force of the second conveyor roller 501 again.

[0029] During use, the limiting slider 703 and the limiting groove 601 cooperate with each other to limit the buffer sleeve 7 in the inner cavity of the buffer sleeve 6, so as to prevent it from falling off.
