Description

Technical Field

[0001] This utility model relates to the technical field of pipe fitting processing and production equipment, and more specifically, to a pipe fitting feeding device. Background Technology

[0002] Currently, before the coating process, the pipes fed into the stainless steel pipe fittings need to be connected end-to-end with a conical rod before being sent to the coating process. When the conical rod is inserted into the stainless steel pipe fitting, it pushes the preceding stainless steel pipe fitting forward through the following stainless steel pipe fitting, so that the two ends of the conical rod are inserted into the preceding and following stainless steel pipe fittings respectively. Because the bottom of the stainless steel pipe fitting abuts against the conveyor roller during transportation, the weight of the stainless steel pipe fitting generates friction on the conveyor roller. The stainless steel pipe fitting is transported by relying on this friction force. However, because the friction force is relatively small, and there are processing errors in the fit between the conical rod and the stainless steel pipe fitting, when the fit between the conical rod and the stainless steel pipe fitting is too tight, the conical rod is not easy to fully insert into the stainless steel pipe fitting, which is a drawback. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a pipe feeding device to ensure that the pipe body and the insertion rod are smoothly connected.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pipe feeding device, comprising a fixed plate, a drive wheel, and a second roller. The upper end of the fixed plate is capable of conveying the pipe body. The fixed plate is provided with an inlet end and an outlet end. The pipe body is conveyed from the inlet end to the outlet end. The drive wheel and the second roller are located on the side near the inlet end. The upper end of the drive wheel abuts against the bottom of the pipe body. The drive wheel rotates along its own axis to feed the pipe body into the fixed plate. The second roller is located above the drive wheel. The second roller can move up and down and can rotate along its own axis. When the second roller moves to the lower limit position, the bottom of the second roller presses down on the pipe body to increase the friction between the pipe body and the drive wheel.

[0005] The present invention is further configured such that both the drive wheel and the roller are fitted with rubber rings on their outer circumferences.

[0006] The present invention is further configured such that the drive wheel is driven to rotate by a motor.

[0007] The present invention is further configured to include a fixing frame, on which a cylinder is mounted, and a connecting seat is mounted on the output end of the cylinder, and a roller is rotatably connected to the connecting seat.

[0008] The present invention is further configured such that the upper end of the fixing plate is provided with a groove, the groove has a triangular cross-section, and the tube moves along the wall of the groove.

[0009] The present invention is further configured such that the length of the tube body is greater than the length of the fixed plate, and when the tube body is fully inserted into the feed end, the side of the tube body away from the feed end extends out of the discharge end, and the side of the tube body extending out of the discharge end is pulled out by a traction device.

[0010] The present invention is further configured such that a bracket three is installed on the fixing plate, and a limiting block is installed on the bracket three, with the bottom of the limiting block close to the upper outer wall of the tube body.

[0011] The present invention is further configured to include a feeding tray, which has an opening on the side near the fixed plate. The opening is higher than the fixed plate, and the feeding tray intermittently feeds the insert rod to the upper part of the fixed plate.

[0012] The present invention is further configured such that a second bracket is installed on the feeding tray, a third cylinder is installed on the second bracket, a second stop block is installed on the output end of the third cylinder, the second stop block is located on the side of the feeding tray near the fixed plate, the second stop block can move up and down, and the second stop block can be inserted into the inner wall of the feeding tray to limit the insertion rod when it moves down.

[0013] The present invention is further configured such that the feed tray is also equipped with a bracket, the bracket is equipped with a cylinder, the output end of the cylinder is equipped with a stop block, the stop block is located on the side of the stop block away from the fixed plate, the stop block can move up and down, and the stop block can press down the upper end of the insert rod when it moves down.

[0014] In summary, this utility model has the following beneficial effects:

[0015] By pressing the tube body down with the rollers, the friction between the tube body and the drive wheel increases, thereby accelerating the delivery of the tube body by the drive wheel. This allows the tube body to catch up with the tube body ahead at a sufficient speed. Furthermore, the increased friction can overcome the resistance when the tube body is inserted into the insertion rod, ensuring a smooth insertion of the tube body and the insertion rod.

[0022] 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.

[0023] like Figures 1-5 As shown, this embodiment discloses a pipe feeding device, including a fixed plate 1, a drive wheel 2, and rollers 3111. The upper end of the fixed plate 1 can transport pipes 5. Specifically, the upper end of the fixed plate 1 is provided with a groove 11, the groove 11 has a triangular cross-section, and the groove 11 extends through both ends of the fixed plate 1 along its length. The fixed plate 1 is provided with an inlet end 13 and an outlet end 14. The pipe 5 moves and is transported along the wall of the groove 11 from the inlet end 13 to the outlet end 14. The length of the pipe 5 is greater than the length of the fixed plate 1. When the pipe 5 is fully inserted into the inlet end 13, the side of the pipe 5 away from the inlet end 13 extends out of the outlet end 14, and the side of the pipe 5 extending out of the outlet end 14 is pulled out by a traction device and then enters the coating process.

[0024] like Figure 1 , Figure 2As shown, the drive wheel 2 and roller 3111 are located near the feed end 13, and both drive wheel 2 and roller 3111 are covered with rubber rings. Drive wheel 2 is driven to rotate by a motor, and roller 3111 is located on both sides above drive wheel 2. The pipe feeding device also includes a fixed frame 3, which is located near the feed end 13. The fixed frame 3 is equipped with a cylinder 31, and a connecting seat 311 is installed at the output end of cylinder 31. Roller 3111 is rotatably connected to the connecting seat 311. Roller 3111 can rotate along its own axis and can move up and down by cylinder 311 to move closer to or away from drive wheel 2. The upper end of drive wheel 2 abuts against the bottom of pipe body 5, and drive wheel 2 rotates along its own axis to feed pipe body 5 into groove 11. The conveying of pipe body 5 relies on its own weight acting on drive wheel 2, and the friction generated by the rotation of drive wheel 2 drives pipe body 5 to move towards fixed plate 1. When the roller 2 3111 moves to the lower limit position, the bottom of the roller 2 3111 presses down on the tube body 5, thereby increasing the friction between the tube body 5 and the drive wheel 2, thus speeding up the conveying of the tube body 5 and reducing the jumping of the tube body 5 during conveying, improving the smoothness of the transmission.

[0025] like Figure 1 , Figure 3 As shown, the fixed plate 1 is equipped with a bracket 6, and the bracket 6 is equipped with a limit block 61. The bottom of the limit block 61 is close to the upper outer wall of the pipe body 5 to reduce the jumping of the pipe body 5 during transportation and improve the stability of the transmission.

[0026] like Figure 1 As shown, the pipe feeding device also includes a feeding tray 4. The feeding tray 4 has an opening on the side near the fixed plate 1, and the opening is higher than the top of the fixed plate 1. The feeding tray 4 intermittently feeds the insert rod 51 to the upper end of the fixed plate 1, and the feeding direction is perpendicular to the length direction of the fixed plate 1. The insert rod 51 is long and narrow, and its axial direction is parallel to the length direction of the fixed plate 1. The bottom surface of the feeding tray 4 is inclined downward towards the side of the fixed plate 1 and can hold the insert rod 51.

[0027] like Figure 1 , Figure 5 As shown, the feed tray 4 is equipped with a second bracket 42, the second bracket 42 is equipped with a third cylinder 421, and the output end of the third cylinder 421 is equipped with a second stop block 4211. The second stop block 4211 is located on the side of the feed tray 4 near the fixed plate 1. The second stop block 4211 can move up and down. When the second stop block 4211 moves down, it can be inserted into the inner wall of the feed tray 4 to limit the insertion rod 51 and prevent the insertion rod 51 from entering the groove 11.

[0028] The feed tray 4 is also equipped with a bracket 41, which in turn is equipped with a cylinder 411. A stop block 4111 is installed at the output end of the cylinder 411. The stop block 4111 is located on the side of the stop block 4211 away from the fixed plate 1. The stop block 4111 can move up and down. When the stop block 4111 moves downward, it presses down on the upper end of the insert rod 51 to prevent the insert rod 51 from entering the groove 11. After the stop block 4211 rises, it releases the insert rod 51 closest to the groove 11, allowing the insert rod 51 to enter the groove 11. At this time, the other insert rod 51 located on the side away from the groove 11 remains fixed in position under the downward pressure of the stop block 4111. After the stop block 4211 moves downward to abut the bottom surface of the feed tray 4, the stop block 4111 releases the insert rod 51 upward, allowing the insert rod 51 to be conveyed one position towards the groove 11. After conveying, the stop block 4111 moves downward to press down on the insert rod 51.

[0029] like Figure 1 As shown, the fixed plate 1 is also equipped with a roller 12, which is located on the side of the fixed plate 1 near the feed end 13, and the tube 5 is conveyed from below the roller 12.

[0030] Once the tube 5 is fully inserted into the feed end 13, the drive wheel 2 no longer controls the movement of the tube 5, and the tube 5 is pulled out primarily by the traction device. The tube 5 is intermittently conveyed to the groove 11, creating a gap between the two tubes 5. The insert rod 51 is then inserted into this gap, positioning it between the two tubes 5. Figure 1 , Figure 5 The tube 5 fed in later is driven by the drive wheel 2 to catch up with the tube 5 fed in earlier and push the insert rod 51 to insert both ends of the insert rod 51 into the two tubes 5 respectively. The insert rod 51 includes bosses 511 at both ends, which are fitted into the tube 5 to complete the insertion of the insert rod 51 into the tube 5, so as to facilitate the subsequent coating process. The roller 2 3111 presses down on the tube 5, which increases the friction between the tube 5 and the drive wheel 2, thereby making the drive wheel 2 speed up the conveying of the tube 5. This allows the tube 5 to catch up with the tube 5 in front at a sufficient speed. The increased friction also overcomes the resistance when the tube 5 and the insert rod 51 are inserted, so as to ensure that the tube 5 and the insert rod 51 are inserted smoothly.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
