Description

Technical Field

[0001] This utility model relates to the field of welded pipe machine technology, specifically to a non-stop horizontal feeding machine for welded pipe machines. Background Technology

[0002] Welded steel pipes, as a commonly used pipe material, are widely used in various fields due to their advantages of low cost and high production efficiency. During their manufacturing process, specialized equipment is needed to precisely transport the billet (steel strip or steel plate) to the welding machine. In this step, the non-stop horizontal feeder used on the welding machine plays a crucial role. However, in actual production, traditional non-stop horizontal feeders for welding machines have revealed many drawbacks. Firstly, the feeding stability is poor; the steel plate is prone to tilting during transport, which not only affects feeding efficiency but may also cause the steel plate to collide with equipment components, resulting in equipment damage, increased maintenance costs, and downtime. Secondly, existing equipment struggles to effectively clean impurities from the surface of thin-walled steel plates. During welding, if particles are mixed into the metal, it will greatly reduce the welding quality, causing defects such as porosity and cracks in the welded pipe, failing to meet the requirements of high-quality projects. For example, in the production of welded pipes for oil pipelines, impurities may not be properly cleaned, leading to leaks in some welded pipes during pressure testing, causing huge economic losses to enterprises. Welded steel pipes, as a widely used type of pipe in modern industry, are characterized by forming a tubular structure through the plastic deformation of steel strips or plates and welding processes, leaving obvious joint marks on the surface. The production process of this type of pipe is quite unique. First, flat steel plates or strips are bent into various cross-sectional shapes such as circles, squares, and rectangles through a precision rolling mill. Then, high-frequency welding, submerged arc welding, and other technologies are used to melt and connect the joints, ultimately forming a finished steel pipe with a closed cavity.

[0003] In CN221087721U, a non-stop horizontal feeder for a pipe welding machine is disclosed, which cleans impurities on the surface of the material by scraping. However, this method is extremely difficult to clean the impurities on the surface of the material thoroughly, and it is easy to leave many small impurities on the surface of the material, which will affect the subsequent welding of the material. Therefore, a non-stop horizontal feeder for a pipe welding machine is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a non-stop horizontal feeding machine for pipe welding machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-stop horizontal feeding machine for a welded pipe machine, comprising a device body, a support plate fixedly connected to one side of the device body, a motor fixedly connected to the upper surface of the support plate, a second gear fixedly connected to the output end of the motor, a transmission rod rotatably connected inside the device body, one end of the transmission rod fixedly connected to one side of the second gear, and a lead screw fixedly connected to the other end of the transmission rod, a support rod fixedly connected to the inner bottom wall of the device body, the outer surface of the end of the lead screw away from the transmission rod rotatably connected to the interior of the support rod, a friction roller sleeved on the outer surface of the lead screw, a sliding groove formed inside the friction roller, a second slider fixedly connected to the outer surface of the transmission rod, the outer surface of the second slider slidably connected to the interior of the sliding groove, and another transmission rod rotatably connected inside the device body near the transmission rod, one end of the other transmission rod fixedly connected to a first gear, the outer surface of the first gear meshing with the outer surface of the second gear.

[0006] Preferably, a sleeve is fixedly connected inside the main body of the device, a threaded rod is threadedly connected inside the sleeve, and a limit ring is fixedly connected to the outer surface of the threaded rod.

[0007] Preferably, a fixed rod is slidably connected to the end of the threaded rod away from the sleeve, and a rotating disk is fixedly connected to the end of the threaded rod near the limiting ring.

[0008] Preferably, a first limiting post is fixedly connected to the upper surface of both ends of the fixing rod, and a first limiting wheel is rotatably connected to the outer surface of the first limiting post.

[0009] Preferably, the device body is fixedly connected to a limiting cylinder, the upper surface of the limiting cylinder is fixedly connected to a second limiting post, the outer surface of the second limiting post is rotatably connected to a second limiting wheel, and material is disposed between the first limiting wheel and the second limiting wheel.

[0010] Preferably, a first slider is slidably connected inside the limiting cylinder, a pull rod is fixedly connected to one side of the first slider, a spring is sleeved on the outer surface of the pull rod, the two ends of the spring are fixedly connected to one side of the first slider and the inner wall of one end of the limiting cylinder, respectively, and the end of the pull rod away from the first slider is fixedly connected to the back of the fixing rod.

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

[0012] 1. This non-stop horizontal feeder for welded pipe machines utilizes a motor to drive the second gear to rotate, causing the second gear to mesh with the first gear and drive two transmission rods to rotate. These two transmission rods drive two lead screws to rotate inside the support rod. The outer surface of the lead screws interacts with the interior of one end of the friction roller. As the transmission rods drive the second slider to rotate the friction roller, the friction roller moves axially on the surface of the lead screw. This allows the friction roller to not only perform rotational cleaning but also axial cleaning on the surface of the material, resulting in a more thorough cleaning of the material surface.

[0013] 2. This non-stop horizontal feeder for welded pipe machines operates by using a rotating disc to drive a threaded rod, which in turn drives the threaded rod through a sleeve. The threaded rod extends out of the sleeve, and a limiting ring pushes a fixed rod, which in turn moves two first limiting wheels and a pull rod, compressing a spring. When the distance between the first and second limiting wheels is sufficient to accommodate the material, the material is inserted into the device, positioning the first and second limiting wheels on either side of the material. The rotating disc is then reversed, causing the limiting ring to stop pushing the fixed rod. The spring then returns to its original position, pushing the first slider to slide inside the limiting cylinder. This clamps and limits the material at the edge of the material, preventing it from shifting during transport and affecting the device's efficiency. Attached Figure Description

The outer surface of the end away from the transmission rod 20 is rotatably connected to the inside of the support rod 4. The outer surface of the lead screw 5 is fitted with a friction roller 6, which cleans the surface of the material 2. The friction roller 6 has a groove 22 inside. The outer surface of the transmission rod 20 is fixedly connected to a second slider 21, and the outer surface of the second slider 21 is slidably connected to the inside of the groove 22. Another transmission rod 20 is rotatably connected to the inside of the device body 1 near the transmission rod 20. One end of the other transmission rod 20 is fixedly connected to a first gear 16, and the outer surface of the first gear 16 meshes with the outer surface of the second gear 17. The meshing of the first gear 16 and the second gear 17 drives the two transmission rods 20 to rotate, which in turn drives the two friction rollers 6 to rotate, thus cleaning the surface of the material 2.

[0021] The device body 1 is internally fixedly connected to a sleeve 23, and the sleeve 23 is internally threadedly connected to a threaded rod 25. The outer surface of the threaded rod 25 is fixedly connected to a limit ring 24. The threaded rod 25 cooperates with the sleeve 23 to push the fixed rod 7 to move.

[0022] The threaded rod 25 is slidably connected to a fixed rod 7 at the end away from the sleeve 23, and a rotating disk 3 is fixedly connected to the end of the threaded rod 25 near the limiting ring 24. The rotating disk 3 is used to drive the threaded rod 25 to rotate.

[0023] The upper surfaces of both ends of the fixed rod 7 are fixedly connected with first limiting posts 9, and the outer surfaces of the first limiting posts 9 are rotatably connected with first limiting wheels 8. The first limiting posts 9 are used to limit the position of the first limiting wheels 8.

[0024] The device body 1 is fixedly connected to a limiting cylinder 11. A second limiting post 12 is fixedly connected to the upper surface of the limiting cylinder 11. A second limiting wheel 13 is rotatably connected to the outer surface of the second limiting post 12. Material 2 is arranged between the first limiting wheel 8 and the second limiting wheel 13. The first limiting wheel 8 and the second limiting wheel 13 cooperate to limit the material 2.

[0025] The limiting cylinder 11 has a first slider 15 slidably connected inside. A pull rod 10 is fixedly connected to one side of the first slider 15. A spring 14 is sleeved on the outer surface of the pull rod 10. The two ends of the spring 14 are fixedly connected to one side of the first slider 15 and the inner wall of one end of the limiting cylinder 11, respectively. The end of the pull rod 10 away from the first slider 15 is fixedly connected to the back of the fixed rod 7. The spring 14 is used to push the first slider 15 to move.

[0026] The drive device that moves material 2 is an existing structure, and will not be described in detail here.

[0027] Among them, the motor 19 is existing technology and will not be described in detail here. Matching the motor 19 are connecting wires, power supply, microcontroller, etc., which are existing structures and will not be described in detail here.

[0028] Working Principle: For this type of non-stop horizontal feeding machine used for welded pipe machines, during use, firstly, the rotating disk 3 is rotated, which drives the threaded rod 25 to rotate, causing the threaded rod 25 to engage in threaded transmission with the sleeve 23. The threaded rod 25 extends out of the sleeve 23 and slides inside the fixed rod 7 until the limiting ring 24 pushes the fixed rod 7 to move. This causes the fixed rod 7 to move the two first limiting wheels 8 and the pull rod 10, causing the pull rod 10 to move the first slider 15 inside the limiting cylinder 11 and compress the spring 14. When the distance between the first limiting wheel 8 and the second limiting wheel 13 is sufficient to accommodate the material 2, the material 2 is inserted into the device, positioning the two first limiting wheels 8 and the second limiting wheel 13 on either side of the material 2. Then, the rotating disk 3 is reversed, causing the limiting ring 24 to stop pushing the fixed rod 7. At this point, the spring 14 returns to its original position, pushing the first slider 15 to slide inside the limiting cylinder 11, thus compressing the first limiting ring 24. The positioning wheel 8 and the second limiting wheel 13 clamp and limit the edge position of the material 2 to prevent the material 2 from shifting inside the device during the conveying process, which would affect the device and the feeding efficiency. At this time, the two friction rollers 6 are located on the upper and lower sides of the material 2. The device sprays water on the surface of the material 2, and then the motor 19 is started. The motor 19 drives the second gear 17 to rotate, so that the second gear 17 meshes with the first gear 16, causing the two transmission rods 20 to rotate. The two transmission rods 20 drive the two lead screws 5 to rotate inside the support rod 4. The outer surface of the lead screw 5 has a transmission effect with the inside of one end of the friction roller 6. While the transmission rod 20 drives the second slider 21 to rotate the friction roller 6, the friction roller 6 moves axially on the surface of the lead screw 5. This makes the friction roller 6 not only rotate and clean the surface of the material 2, but also move axially to clean it, making the surface of the material 2 cleaner.
