Description

Technical Field

[0001] This utility model relates to the field of steel pipe feeding, specifically to a drive roller assembly for a steel pipe processing part feeding device. Background Technology

[0002] During the processing of steel pipe components, automatic feeding equipment is needed to ensure continuous feeding of steel pipes, thereby improving the continuity of operations, making the processing flow smoother and more efficient, and avoiding the impact on overall production efficiency due to feeding interruptions.

[0003] Currently, most automatic steel pipe feeding equipment uses conveyor belts or roller conveyors. These automatic conveying equipment often only have the function of automatic feeding, but lack a structure for effectively positioning the steel pipe. This means that after the steel pipe is fed, it still needs to be manually positioned, which increases the number of operation steps and reduces processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a drive roller assembly for a steel pipe processing feeding device. The drive roller, with its hourglass-shaped structure, and two sets of positioning rollers can radially limit the movement of the steel pipe, thus solving the problem of lacking a positioning structure during transport, facilitating subsequent cutting or welding of the steel pipe. A motor drives a rotating rod to rotate, which, in conjunction with the drive roller and anti-slip silicone pad, pushes the steel pipe, ensuring smooth transport along its axial direction, thereby achieving positioned feeding of the steel pipe. Adjusting the height of the positioning frame with an electric push rod allows the drive roller to radially limit steel pipes of different diameters, thereby improving the overall flexibility and practicality of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drive roller assembly for a steel pipe processing part feeding device, comprising: A base, wherein a positioning roller is rotatably connected to the inner wall of the base, and an electric push rod is fixedly connected to the inner wall of the base; A positioning frame, which is slidably connected to the inner wall of the base; A stepper motor is fixedly connected to the outer right side of the positioning frame. A rotating rod is fixedly connected to the output end of the stepper motor, and a drive roller is fixedly connected to the outer wall of the rotating rod.

[0006] Preferably, the output end of the electric push rod is fixedly connected to the bottom of the positioning frame.

[0007] Preferably, both the positioning roller and the drive roller are fixedly connected to the outer walls with anti-slip silicone pads.

[0008] Preferably, a connecting block is fixedly connected to the outer wall of the base, and the connecting block has through holes for inserting fasteners.

[0009] Preferably, the positioning roller has an hourglass-shaped structure that is wide at both ends and narrow in the middle. The end faces of the positioning roller are circular, and the two ends of the positioning roller transition smoothly into a conical shape towards the middle. The positioning roller has the same shape as the drive roller.

[0010] Preferably, the positioning rollers are provided in two sets, and the two sets of positioning rollers are mirror images of each other on the inner wall of the base with the central axis of the drive roller as the central axis.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention utilizes an hourglass-shaped drive roller and two sets of positioning rollers to not only limit the radial movement of the steel pipe but also allow it to move smoothly along its axial direction. This enables automatic feeding of the steel pipe without the need for further positioning, facilitating subsequent cutting or welding. The electric push rod design, combined with the positioning frame, allows for adjustable height of the drive roller. This height adjustment enables radial clamping of steel pipes of different diameters, enhancing the overall flexibility and practicality of the device. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1 - Figure 3The shown is a drive roller assembly for a steel pipe processing part feeding device, including a base 1, a positioning frame 2 and a stepper motor 3; A positioning roller 4 is rotatably connected to the inner wall of the base 1. The positioning roller 4 can provide stable support for the steel pipe. An electric push rod 8 is fixedly connected to the inner wall of the base 1. The output end of the electric push rod 8 is fixedly connected to the bottom of the positioning frame 2. Activating the electric push rod 8 can drive the positioning frame 2 to slide up and down on the inner wall of the base 1. The positioning frame 2 is slidably connected to the inner wall of the base 1. The height of the drive roller 6 can be adjusted by sliding the positioning frame 2, so as to position the steel pipes at different distances. like Figure 3 - Figure 4 As shown, the stepper motor 3 is fixedly connected to the right outer wall of the positioning frame 2. The output end of the stepper motor 3 is fixedly connected to the rotating rod 5. The outer wall of the rotating rod 5 is fixedly connected to the drive roller 6. When the stepper motor 3 is started, it drives the rotating rod 5 to rotate. When the rotating rod 5 rotates, it drives the drive roller 6 to rotate synchronously.

[0017] like Figure 1 - Figure 3 As shown, the positioning roller 4 has an hourglass-shaped structure that is wide at both ends and narrow in the middle. The end faces of the positioning roller 4 are round, and the two ends of the positioning roller 4 transition smoothly into a conical shape towards the middle. The positioning roller 4 has the same shape as the drive roller 6. The positioning roller 4 and the drive roller 6 with the hourglass structure can limit the radial movement of the steel pipe and can clamp steel pipes of different sizes, thereby improving the stability of the steel pipe positioning.

[0018] like Figure 1 - Figure 3 As shown, anti-slip silicone pads 7 are fixedly connected to the outer walls of both the positioning roller 4 and the drive roller 6. Through the excellent elasticity and friction of the anti-slip silicone pads 7, the drive roller 6 can push the steel pipe during rotation, causing the steel pipe to move along its axial direction. At the same time, the steel pipe will push the positioning roller 4, causing the positioning roller 4 to rotate on the inner wall of the base 1.

[0019] like Figure 1 - Figure 2 As shown, a connecting block 9 is fixedly connected to the outer wall of the base 1. The connecting block 9 has a through hole 10 for inserting fasteners. The bolt is passed through the through hole 10 and locked in the processing area of ​​the equipment or the processing table. At this time, the position of the base 1 can be fixed by using the bolt and the connecting block 9, so that the base 1 can stably feed the steel pipe.

[0020] like Figure 1 - Figure 2As shown, there are two sets of positioning rollers 4. The two sets of positioning rollers 4 are mirror images of the driving roller 6 on the inner wall of the base 1. When the driving roller 6 presses the steel pipe against the outer wall of the positioning rollers 4, the two sets of positioning rollers 4 can effectively support the steel pipe, preventing it from swinging up and down, thus ensuring that the steel pipe remains stable during the conveying process.

[0021] The working principle of this practical system is as follows: Insert the steel pipe to be fed into the gap between the positioning roller 4 and the drive roller 6. Then, activate the electric push rod 8 to drive the positioning frame 2 to slide downwards on the inner wall of the base 1. Simultaneously, the positioning frame 2 slides downwards, driving the stepper motor 3 to move downwards synchronously. This causes the rotating rod 5 and the drive roller 6 to move downwards synchronously until the drive roller 6 presses the steel pipe tightly against the outer wall of the positioning roller 4. At this point, the electric push rod 8 can be closed. The drive roller 6, in conjunction with the two sets of positioning rollers 4, can radially clamp the steel pipe, ensuring the steel pipe is held between the drive roller 6 and the positioning rollers 4. The steel pipe can only move axially between the positioning roller 4 and the driving roller 6. Then, the stepper motor 3 is started to drive the rotating rod 5 to rotate. As the rotating rod 5 rotates, it drives the driving roller 6 to rotate synchronously. The rotation of the driving roller 6, combined with the excellent friction of the anti-slip silicone pad 7, can push the steel pipe, so that the steel pipe can move axially between the positioning roller 4 and the driving roller 6. In this way, the steel pipe can be automatically fed. Under the axial limiting action of the driving roller 6 and the positioning roller 4, the steel pipe can move smoothly along its axial direction, thereby realizing the positioning and feeding of the steel pipe for subsequent cutting or welding processing.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
