Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment, specifically a marking device for pipe production. Background Technology

[0002] In the pipe manufacturing process, marking equipment is used to mark important information such as product specifications, production date, and batch number on the surface of the pipe, which is crucial for product traceability and quality control.

[0003] Currently available marking equipment often requires different dedicated limiting devices for different shaped tubes, such as round and square tubes. For example, round tube limiting typically uses V-groove rollers or conical wheels, but these structures are difficult to adapt to the planar contour of square tubes; square tube limiting commonly uses planar guide plates or right-angle slots, but these cannot provide stable circumferential positioning for round tubes, thus their functions are relatively limited. Utility Model Content

[0004] The purpose of this utility model is to provide a marking device for pipe production, so as to solve the problem that the limiting device of conventional marking devices mentioned in the background art has a relatively simple function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a marking device for pipe production, comprising a conveying device, a marking device, and a gantry support disposed above the conveying device. A pair of sliders are slidably mounted on the gantry support, and a connecting arm is rotatably mounted on the bottom of the sliders. The connecting arm is connected to the sliders by a tension spring, and a swing arm assembled from a mounting frame, a first roller, and two second rollers is rotatably mounted on the bottom of the connecting arm through a limiting component.

[0006] Preferably, one end of the slider is provided with a limiting groove, and one side of the connecting arm is rotated by the tension spring to abut against the limiting groove.

[0007] Preferably, the limiting component is a positioning rod fixedly installed on the connecting arm, the connecting arm is sleeved at the center of the positioning rod, a positioning block and a spring are sleeved on one side of the positioning rod, a positioning pin is fixedly installed on the side of the positioning block near the mounting frame, and a pair of insertion holes for accommodating the positioning pin are provided on the side wall of the mounting frame.

[0008] Preferably, the connecting arm is provided with a groove for hooking the tension spring.

[0009] Preferably, the end of the mounting bracket away from the second roller is configured as a U-shaped structure, and the first roller and the second roller are rotatably connected to the mounting bracket via rotating shafts.

[0010] Preferably, the second roller has a conical structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention achieves the function of limiting various types of pipes through a swing arm. Adjusting the angle of the mounting bracket allows for switching the limiting wheels, enabling the device to limit both round and square pipes. The first and second rollers are integrated on a single mounting bracket, making the entire pipe marking device more compact, simple in structure, and easy to operate, thus making the production process more efficient and smooth.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 and Figure 2This utility model provides a technical solution: a marking device for pipe production, including a conveying device 1, a marking device 2, and a gantry support 3 located above the conveying device 1. The conveying device 1 is responsible for driving the pipe to move at a set speed and direction, ensuring that the pipe can accurately pass through the marking area located below the marking device 2. A pair of sliders 4 are slidably installed on the gantry support 3. A screw is provided on one side of the slider 4 and is locked to a designated position on the gantry support 3 by the screw. A connecting arm 5 is rotatably installed on the bottom of the slider 4. The connecting arm 5 is connected to the slider 4 by a tension spring 9. The connecting arm 5 is provided with a groove for hooking the tension spring 9. One end of the slider 4 is provided with a limiting groove. One side of the connecting arm 5 is rotated by the tension spring 9 to abut against the limiting groove. The advantage of this setting is that the connecting arm 5 has a certain elastic adjustment capability. When pipes of different diameters pass through, the tension spring 9 can automatically adjust the position of the connecting arm 5 according to the change in pipe diameter, so that the device can adapt to various specifications of pipes and improve the versatility and flexibility of the device.

[0020] Please see Figures 2-4 The bottom of the connecting arm 5 is rotatably mounted with a swing arm consisting of a mounting frame 6, a first roller 7, and two second rollers 8 via a limiting assembly. The first roller 7 and the second rollers 8 are guide wheels for pipe coding and conveying. The end of the mounting frame 6 away from the second rollers 8 is designed with a U-shape. The first roller 7 and the second rollers 8 are rotatably connected to the mounting frame 6 via rotating shafts. The second rollers 8 are conical in shape. The two opposing second rollers 8 can apply force to both sides of the pipe simultaneously, making the force on the pipe more uniform during conveying, reducing the swaying or rolling phenomenon caused by uneven force on the pipe, improving the stability of pipe conveying, and helping to improve coding quality and efficiency. The limiting assembly is a positioning rod 10 fixedly mounted on the connecting arm 5. The connecting arm 5 is sleeved at the center of the positioning rod 10. A positioning block 12 and a spring 11 are sleeved on one side of the positioning rod 10. A positioning pin 13 is fixedly mounted on the side of the positioning block 12 near the mounting frame 6. The side wall of the mounting frame 6 has a pair of insertion holes for accommodating the positioning pin 13.

[0021] The first roller 7 is a straight roller, which can fit well with the plane of the square tube and is suitable for limiting the square tube. The tapered structure of the second roller 8 can form line contact with the surface of the round tube, providing concentrated pressure on a small contact area, effectively limiting the lateral or longitudinal movement of the round tube, and is suitable for limiting the round tube. When it is necessary to adjust the mounting bracket 6 used for guidance according to the shape of the tube, the positioning block 12 is pulled to slide on the positioning rod 10 and compress the spring 11. After the positioning pin 13 disengages from the insertion hole of the mounting bracket 6, the position can be rotated for adjustment.

[0022] This application achieves the function of limiting various types of pipes through the swing arm. Adjusting the angle of the mounting frame 6 can switch the limiting wheels, so that the device can limit both round pipes and square pipes. The first roller 7 and the second roller 8 are integrated on a mounting frame 6. The structure of the entire pipe marking device is more compact, simple, and easy to operate, making the production process more efficient and smooth.
