A feeding roller conveyor for a high-frequency welded pipe unit

Abstract

This utility model discloses a feeding roller conveyor for a high-frequency welded pipe unit, including a mounting base plate, a feeding assembly above the mounting base plate, and a support assembly on the upper surface of the mounting base plate. By starting a servo motor, the servo motor can drive a first conveyor roller to rotate via a first support shaft to convey the formed pipe body. At the same time, the rotating first conveyor roller will drive a second conveyor roller to rotate in the same direction as the first conveyor roller via a first synchronous pulley, a synchronous belt, a second synchronous pulley, and a second support shaft. The limiting roller will also limit and guide the passing formed pipe body, thereby preventing the formed pipe body from swaying up and down or back and forth during the conveying process, thus ensuring the stability of the formed pipe body during conveying. By installing fixing screws and opening mounting threaded holes, it is convenient for operators to disassemble, replace, and maintain the first conveyor roller, the second conveyor roller, and the limiting roller in the future.

Description

Technical Field

[0001] This utility model relates to the field of high-frequency welded pipe feeding technology, specifically a feeding roller conveyor for a high-frequency welded pipe unit. Background Technology

[0002] High-frequency welded pipe unit is a device that rolls long strips of steel of a certain specification into round tubes and welds straight seams into steel pipes. After the high-frequency welded pipe unit welds the steel pipes, a feeding roller conveyor is needed to transport the formed pipes to the next process.

[0003] In the prior art, a high-frequency welded pipe unit feeding roller conveyor with the publication number "CN217172222U" uses guide wheels that slide on the surface of the workpiece. When the guide wheels are subjected to force, they push the guide seat to move outward. The movement of the guide seat drives the movable column to move, and the movable column slides inside the top frame. The movement of the guide seat causes the buffer spring to deform, which achieves the advantage of preventing falling and solves the problem that the existing high-frequency welded pipe unit feeding roller conveyors do not have the function of preventing falling during use.

[0004] However, the above technical solutions and existing technologies have the following drawbacks:

[0005] Although the feeding roller conveyor can limit and guide the pipe workpiece, the guide wheels can only limit the pipe workpiece laterally, but not vertically. This causes the pipe workpiece to shift and sway upwards during the conveying process, so the conveying stability needs to be further improved. In addition, the roller conveyor body is not easy to disassemble during actual use, making it inconvenient for staff to replace the worn roller conveyor body later, resulting in poor practicality.

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] Example 1:

[0027] A feeding roller conveyor for a high-frequency welded pipe unit includes a support platform 1 and a mounting base plate 2. The mounting base plate 2 is installed on the upper surface of the support platform 1 and is fixed to the upper surface of the support platform 1 by bolts. The mounting base plate 2 can support and fix the support component 4. The formed pipe body 3, which has been welded by the external high-frequency welded pipe unit, is inserted above the mounting base plate 2. Since the internal detailed structure and working principle of the high-frequency welded pipe unit are relatively mature technologies in the prior art, they will not be described in detail here. A feeding component 5 is provided above the mounting base plate 2. The feeding component 5 is used to convey and limit the formed pipe body 3 to prevent the formed pipe body 3 from shifting or shaking during the conveying process. The support component 4 is provided on the upper surface of the mounting base plate 2. The support component 4 can not only support the feeding component 5, but also has the ability to be disassembled and reassembled, so that maintenance personnel can disassemble, replace and maintain the feeding component 5 later.

[0028] The feeding assembly 5 includes a servo motor 51, a limiting roller 52, a first conveying roller 53, a first support shaft 511, and a third support shaft 512. The servo motor 51 is mounted on the rear end face of the second bottom support plate 43. The servo motor 51 is electrically connected to an external servo controller via wires. A coupling is provided between the servo motor 51 and the first support shaft 511. Figure 3(As shown in the drawing), a first support shaft 511 is installed at the front end of the servo motor 51. The first support shaft 511 and the first conveying roller 53 are an integral structure. When the servo motor 51 is working, it drives the first support shaft 511 to rotate through the coupling, so that the first support shaft 511 drives the first synchronous pulley 54 and the first conveying roller 53 to rotate. The first conveying roller 53 is provided on the annular side of the first support shaft 511. The first conveying roller 53 can support and convey the forming tube. A third support shaft 512 is installed between the first middle support plate 42 and the second middle support plate 44. The third support shaft 512 and the limiting roller 52 are an integral structure. The third support shaft 512 can not only support the limiting roller 52, but also enable the limiting roller 52 to rotate. The limiting roller 52 is provided on the annular side of the third support shaft 512. The limiting roller 52 can limit the forming tube 3 on the first conveying roller 53 and the second conveying roller 58, so as to prevent the forming tube 3 from swaying up and down or swaying back and forth during the conveying process.

[0029] A first synchronous pulley 54 is provided at the front end of the first support shaft 511. The first synchronous pulley 54 is connected to the first support shaft 511 by welding. A second synchronous pulley 57 is provided on the left side of the first synchronous pulley 54. The second synchronous pulley 57 is connected to the second support shaft 59 by welding. A synchronous belt 55 connects the first synchronous pulley 54 and the second synchronous pulley 57. When the first synchronous pulley 54 rotates, it drives the second synchronous pulley 57 to rotate together through the synchronous belt 55. The second synchronous pulley 57 drives the second conveyor roller 58 to rotate through the second support shaft 59. The second support shaft 59 is connected to the middle of the rear end face of the second synchronous pulley 57. The second support shaft 59 is connected to the second conveyor roller. Both 58 and the follower ring 591 are connected by welding. The second support shaft 59 not only supports the second conveyor roller 58, but also enables the second conveyor roller 58 to rotate. The second conveyor roller 58 is provided on the annular side of the second support shaft 59. The second conveyor roller 58 has the same specifications as the first conveyor roller 53 and the limiting roller 52. The second conveyor roller 58 can assist in conveying the forming tube 3. The annular sides of the first conveyor roller 53 and the second conveyor roller 58 are provided with anti-slip textures. The anti-slip textures make the annular sides of the first conveyor roller 53 and the second conveyor roller 58 more slip-resistant, preventing the first conveyor roller 53 and the second conveyor roller 58 from easily slipping during the conveying of the forming tube 3.

[0030] A follower ring 591 is provided on the front side of the annular side of the second support shaft 59, and the follower ring 591 is an integral structure with the second support shaft 59. A limit cover 56 is provided on the front end face of the follower ring 591, and the limit cover 56 is circular in shape. The limit cover 56 is fixed to the front end face of the first bottom support plate 41 and the first middle support plate 42 on the left side by screws. The follower ring 591 and the limit cover 56 can prevent the second support shaft 59 from shifting or shaking during use. The annular sides of the first conveyor roller 53, the second conveyor roller 58, and the limit roller 52 are all provided with limit grooves, and the limit grooves match the forming tube 3. The limit grooves enable the first conveyor roller 53, the second conveyor roller 58, and the limit roller 52 to limit the forming tube 3, preventing the forming tube 3 from shifting or shaking during conveying. The conveying direction of the forming tube 3 is... Figure 1 It has already been drawn in the middle.

[0031] Example 2:

[0032] Based on Embodiment 1, this embodiment uses a fixing screw 46 and a threaded hole 48 to facilitate the disassembly of the first bottom support plate 41, the first middle support plate 42, the first cover plate 47, the second bottom support plate 43, the second middle support plate 44, and the second cover plate 45 by workers, so that the first conveying roller 53, the second conveying roller 58, and the limiting roller 52 can be disassembled, replaced, and maintained later.

[0033] The support assembly 4 includes a first bottom support plate 41, a first middle support plate 42, a second bottom support plate 43, a second middle support plate 44, a second cover plate 45, a fixing screw 46, and a first cover plate 47. The first bottom support plate 41 is fixedly connected to the front side of the upper end face of the mounting base plate 2. The first bottom support plate 41 is connected to the mounting base plate 2 by welding. The second bottom support plate 43 is fixedly connected to the rear side of the upper end face of the mounting base plate 2. The second bottom support plate 43 is connected to the mounting base plate 2 by welding. There are two sets of the first bottom support plate 41 and the second bottom support plate 43. The two sets of the first bottom support plate 41 and the second bottom support plate 43 can respectively support and limit the first support shaft 511 and the second support shaft 59.

[0034] A first middle support plate 42 is assembled on the upper surface of the first bottom support plate 41, and a second middle support plate 44 is assembled on the upper surface of the second bottom support plate 43. Two sets of the first middle support plate 42 and the second middle support plate 44 are assembled. The two sets of second middle support plates 44 can support and limit the third support shafts 512 on the left and right sides respectively. A first cover plate 47 is assembled on the upper surface of the first middle support plate 42, and a second cover plate 45 is installed on the upper surface of the second middle support plate 44. The first cover plate 47 and the second cover plate 45 can block and limit the third support shafts 512 on the left and right sides respectively, so as to prevent the third support shafts 512 on the left and right sides from shaking and displacement during rotation and use.

[0035] The first middle support plate 42 is assembled and fixed to the first cover plate 47 and the first bottom support plate 41, as well as the second middle support plate 44, the second cover plate 45, and the second bottom support plate 43, through fixing screws 46. The upper surfaces of the first bottom support plate 41 and the second bottom support plate 43 are symmetrically provided with mounting threaded holes 48 on both sides, and these threaded holes 48 are threadedly connected to the fixing screws 46. The mounting threaded holes 48 and the fixing screws 46 allow for assembly and fixing or disassembly of the first middle support plate 42, the first cover plate 47, the first bottom support plate 41, the second middle support plate 44, the second cover plate 45, and the second bottom support plate 43. The fixing screws 46 are high-strength screws, ensuring high mechanical strength and preventing breakage during use. The first cover plate 47, the first middle support plate 42, the second cover plate 45, and the second middle support rod are symmetrically provided with through holes on both sides. Figure 4 (As shown in the drawing), and the through hole matches the fixing screw 46. The through hole facilitates the fixing screw 46 to be inserted and fixed inside the first cover plate 47, the first middle support plate 42, the second cover plate 45, and the second middle support rod.

[0036] Anti-misalignment holes 49 are symmetrically provided on the left and right sides of the upper end faces of the first bottom support plate 41, the first middle support plate 42, the second bottom support plate 43, and the second middle support plate 44. Anti-misalignment heads 411 are symmetrically provided on the left and right sides of the lower end faces of the first cover plate 47, the first middle support plate 42, the second cover plate 45, and the second middle support plate 44. Multiple anti-misalignment heads 411 are provided. The multiple anti-misalignment heads 411 are connected to the first cover plate 47, the first middle support plate 42, the second cover plate 45, and the second middle support plate 44 by welding. The anti-misalignment heads 411 match the anti-misalignment holes 49. The matching anti-misalignment heads 411 and anti-misalignment holes 49 prevent misalignment when the first middle support plate 42 is assembled with the first cover plate 47 and the first bottom support plate 41, and when the second middle support plate 44 is assembled with the second cover plate 45 and the second bottom support plate 43.

[0037] Working principle: When it is necessary to convey the formed tube body 3 after welding by the external high-frequency welded pipe unit, the operator only needs to start the servo motor 51, which will drive the first support shaft 511 to rotate. The first support shaft 511 will drive the first conveying roller 53 and the first synchronous pulley 54 to rotate together. During this process, the rotating first conveying roller 53 will convey the formed tube body 3 at the upper end to the left. The first synchronous pulley 54 will drive the second synchronous pulley 57 to rotate in the same direction through the synchronous belt 55. The second synchronous pulley 57 will drive the second conveying roller 58 to rotate in the same direction as the first conveying roller 53 through the second support shaft 59, thereby ensuring the stability of the formed tube body 3 being conveyed. At the same time, the limiting roller 52 will also limit and guide the passing formed tube body 3, thereby preventing the formed tube body 3 from shaking or deviating during the conveying process.

[0038] By installing the fixing screw 46 and opening the installation threaded hole 48, it is convenient for the staff to disassemble the first bottom support plate 41, the first middle support plate 42, the first cover plate 47, the second bottom support plate 43, the second middle support plate 44, and the second cover plate 45 separately. This allows the staff to disassemble, replace, and maintain the first conveyor roller 53, the second conveyor roller 58, and the limiting roller 52 separately later. By setting the anti-misalignment head 411 and opening the anti-misalignment hole 49, the first middle support plate 42, the first cover plate 47, the second middle support plate 44, and the second cover plate 45 can be limited during the assembly process to prevent misalignment of the first middle support plate 42, the first cover plate 47, the second middle support plate 44, and the second cover plate 45 during assembly and use, thereby ensuring the stability of the first middle support plate 42, the first cover plate 47, the second middle support plate 44, and the second cover plate 45 in use.
