Description

Technical Field

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

[0002] Aluminum profiles are long strip structures and are mainly produced by extrusion molding. They also require painting and other processes during production, so they need to be pulled and transported by a traction device.

[0003] In the process of traction and conveying aluminum profiles, the aluminum profiles are mostly placed on the surface of the conveyor belt or conveyor rollers for conveying. In this conveying method, the drive rollers and motors and other drive mechanisms inevitably generate vibrations. These vibrations will directly cause the aluminum profiles on the conveyor belt or conveyor rollers to shift, which will directly affect the state of the aluminum profiles when they enter the next processing step, thus affecting the processing effect of the aluminum profiles. Therefore, there is an urgent need for a traction device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a traction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a traction device, comprising two mounting plates for mounting an aluminum profile traction mechanism and a traction drive roller for traction of the aluminum profile, wherein a traction roller is rotatably mounted between the two mounting plates;

[0006] A fixing plate is fixedly installed on the side wall of each of the two mounting plates. A sliding groove is opened horizontally on the top surface of the fixing plate. A slider is slidably installed inside the sliding groove. A push spring is fixedly installed on the side of each of the two sliding grooves away from the mounting plate. The end of the push spring is fixedly connected to the slider. An L-shaped plate is fixedly installed on the top surface of the two sliders. A strip plate is fixedly installed on the opposite side of the two L-shaped plates.

[0007] Multiple arc-shaped grooves are provided on one side of each of the two strip plates. The drive roller is rotatably installed inside the multiple arc-shaped grooves, and the shaft of the drive roller extends to the top of the strip plate and is fixedly sleeved with a synchronous pulley. The multiple synchronous pulleys are connected by multiple synchronous belts.

[0008] Two guide plates are symmetrically fixedly installed on the top surfaces of the two mounting plates, and multiple guide rollers are rotatably installed on the opposite sides of the two guide plates.

[0009] Preferably, two limiting blocks are symmetrically fixedly installed on the sidewalls of the two sliders, and two limiting grooves are symmetrically opened on the inner wall of the slide groove.

[0010] Preferably, the two limiting blocks symmetrically fixedly installed on the sidewall of the slider are slidably connected to the inside of the two limiting grooves opened on the inner wall of the slide groove.

[0011] Preferably, a limiting rod is fixedly installed laterally inside the slide groove, and a limiting hole is formed through the side wall of the slider.

[0012] Preferably, the limiting rod slides through the limiting hole opened in the side wall of the slider.

[0013] Preferably, an arc-shaped plate is fixedly installed on one side of each of the two strip plates near the two guide plates.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This traction device, thanks to the structure of a fixed plate, push spring, slider, L-shaped plate, strip plate, and drive roller, can push the slider to one side of the traction roller through the push spring, while simultaneously moving the L-shaped plate and strip plate fixedly mounted on the top surface of the slider towards the traction roller and fitting them against the surface of the aluminum profile. At the same time, the aluminum profile is pulled by multiple drive rollers, and due to the arrangement of the push spring and slider, the strip plate has a certain movement stroke, thereby realizing the traction drive of aluminum profiles of different sizes.

[0016] Thanks to the setup of two guide plates and guide rollers, this traction device can initially adjust the position of the aluminum profile on the top surface of the traction roller, allowing the aluminum profile to move laterally to the middle of the traction roller, thus facilitating subsequent traction of the clamping plate.

[0017] Compared with existing technologies, this traction device can not only position the aluminum profile correctly, but also clamp and pull it, thereby enabling stable traction and transportation of the aluminum profile. Attached Figure Description

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 4 The main structure of the traction device shown is two mounting plates 1 for mounting the aluminum profile traction mechanism and a drive roller 8 for traction of the aluminum profile. A traction roller 2 is rotatably mounted between the two mounting plates 1. The multiple traction rollers 2 are synchronously driven by a structure such as a sprocket and a chain. This drive structure is common knowledge, so it will not be described in detail in the accompanying drawings of the specification.

[0029] A fixing plate 3 is fixedly installed on the side wall of each of the two mounting plates 1. A sliding groove 4 is opened horizontally on the top surface of the fixing plate 3. A slider 5 is slidably installed inside the sliding groove 4. A push spring 11 is fixedly installed on the side of the two sliding grooves 4 away from the mounting plate 1. Since the push spring 11 is installed between the side of the sliding groove 4 away from the mounting plate 1 and the side wall of the slider 5, the push spring 11 can push the slider 5 to move towards the side of the mounting plate 1, so that the slider 5 has a certain sliding stroke, thereby enabling the clamping and pulling of aluminum profiles of different sizes.

[0030] The end of the push spring 11 is fixedly connected to the slider 5. The top surfaces of the two sliders 5 are fixedly mounted with L-shaped plates 6. The opposite side of the two L-shaped plates 6 is fixedly mounted with strip plates 7. Multiple arc-shaped grooves are opened on the opposite side of the two strip plates 7. The drive rollers 8 are rotatably mounted inside the multiple arc-shaped grooves. One side of the multiple drive rollers 8 is rotatably extended to the outside of the arc-shaped grooves. In this way, when the strip plates 7 approach and press the aluminum profile, the multiple drive rollers 8 will preferentially contact the aluminum profile, thereby effectively driving the aluminum profile.

[0031] The shaft of the drive roller 8 extends to the top of the strip plate 7 and is fixedly fitted with a synchronous pulley 9. Multiple synchronous pulleys 9 are connected by multiple synchronous belts 10. A motor is fixedly installed above one of the synchronous pulleys 9, and the side wall of the motor is fixed to the top surface of the mounting plate 1 through a connecting plate. The synchronous pulleys 9 and synchronous belts 10 drive the rollers 8 to rotate synchronously, thereby further improving the traction effect of the aluminum profile.

[0032] Two guide plates 12 are symmetrically fixedly installed on the top surface of the two mounting plates 1. Multiple guide rollers 13 are rotatably installed on the opposite side of the two guide plates 12. Thanks to the structure of the two guide plates 12 and guide rollers 13, the position of the aluminum profile on the top surface of the traction roller 2 can be initially adjusted, so that the aluminum profile moves laterally to the middle part of the traction roller 2, which facilitates the subsequent clamping and traction of the aluminum profile.

[0033] Two limiting blocks 14 are symmetrically fixedly installed on the side walls of the two sliders 5, and two limiting grooves are symmetrically opened on the inner wall of the slide groove 4. The two limiting blocks 14 symmetrically fixedly installed on the side walls of the sliders 5 are slidably connected to the inside of the two limiting grooves opened on the inner wall of the slide groove 4. Thanks to the setting of the two limiting blocks 14, the sliding direction of the sliders 5 can be effectively limited, and the stability of the sliders 5, L-shaped plate 6 and strip plate 7 during sliding can be further improved.

[0034] A limiting rod 15 is fixedly installed horizontally inside the slide 4. A limiting hole is opened through the side wall of the slider 5. The limiting rod 15 slides through the limiting hole opened in the side wall of the slider 5. Thanks to the setting of the limiting rod 15, the sliding direction of the slider 5 can be further limited.

[0035] Two strip plates 7 are fixedly installed with arc plates 16 on the side near the two guide plates 12. The two arc plates 16 can further guide the aluminum profile, so that the aluminum profile moves between the two strip plates 7.

[0036] Working principle

[0037] In use, when the aluminum profile is driven by the traction roller 2 and vibrates, causing it to shift, one end of the aluminum profile contacts the two guide plates 12. At this time, the guide plates 12 provide initial guidance to the aluminum profile, causing it to move to the middle of the traction roller 2. Subsequently, as the aluminum profile is pulled, it moves between the two strip plates 7. At this time, the two push springs 11 push the slider 5, which is fixedly installed at the end of the push spring 11, to slide along the slide groove 4. At the same time, the slider 5 drives the L-shaped plate 6 and the strip plate 7, which are fixedly installed on its top surface, to move towards the aluminum profile, causing multiple drive rollers 8 to stick to the surface of the aluminum profile. In this way, the multiple drive rollers 8 squeeze and drive the aluminum profile, thereby positioning and pulling the aluminum profile.
