Abstract
Description
Technical Field
[0001] This application relates to the technical field of corrugated flue processing, and in particular to an automatic flue corrugating machine. Background Technology
[0002] For a long time, the plastic and aluminum alloy exhaust ducts used in some scenarios have revealed significant shortcomings: although plastic is lightweight and inexpensive, its temperature threshold is low (the long-term operating temperature is usually below 80℃), and it is prone to softening, deformation, or even melting and dripping when exposed to high-temperature flue gas. Furthermore, its flammability exacerbates the fire hazard. Using stainless steel exhaust ducts can avoid these problems. During the production process, stainless steel exhaust pipes require a corrugating machine to process them. The processed stainless steel exhaust pipe will have a corrugated structure in the middle, making it easy to bend the corrugated pipe to a 90-degree angle using bending equipment, ultimately using it as a 90-degree elbow in the flue pipe.
[0003] Existing wave-forming machines require a cylinder to drive grippers to hold the pipe, then transport the pipe to the inlet. Once the pipe is fully inside the wave-forming machine, it is fitted onto a support shaft. The machine then processes the pipe, pushing a rod towards the inlet. After processing, part of the pipe rests on the support shaft, while the other end extends from the inlet. The extended portion is gripped by the grippers, and the processed pipe is removed from the machine. Finally, the cylinder drives the grippers to move the unprocessed pipe from the inlet into the wave-forming machine for further processing.
[0004] In the aforementioned related technologies, the cylinder drives the gripper to move, and then the gripper clamps the end of the pipe. During the clamping process, one end of the pipe is clamped by the gripper, while the other end, which is not clamped, tends to tilt downwards under the action of gravity. As a result, during the feeding and unloading process, the pipe is prone to tilting downwards along the position where the gripper is clamped, which ultimately affects the quality of the pipe. Utility Model Content
[0005] To address at least one of the aforementioned problems, this utility model first provides an automatic pipe wave-forming machine, comprising a frame and a wave-forming machine body mounted on the frame. A support shaft is mounted on the wave-forming machine body, and a feeding assembly is mounted on the frame. The feeding assembly is used to transport pipes through an inlet to the support shaft. The feeding assembly includes a rotating shaft fixed on the frame, a feeding disc fixed on the rotating shaft, and an arc-shaped limiting plate fixed on the frame. The feeding disc has multiple discharge slots spaced circumferentially around the feeding disc. The arc-shaped limiting plate is used to block the openings of the discharge slots. A pushing assembly is mounted on the frame to move the pipes in the discharge slots into the wave-forming machine body.
[0006] Optionally, the pushing assembly includes a pushing cylinder and a pushing plate fixed on the piston rod of the pushing cylinder. The pushing cylinder drives the pushing plate to move, so that the pushing plate moves into the discharge trough, and pushes the pipe in the discharge trough to the wave-making machine body through the feed port.
[0007] Optionally, a moving component is provided on the frame, which is used to drive the actuating component to reciprocate along the axis of the feeding tray; the moving component includes a moving cylinder fixed on the arc-shaped limiting plate and a moving frame fixed on the moving cylinder, and an actuating component is provided on the moving frame, which is used to actuate the pipe completely away from the support shaft.
[0008] Optionally, the actuating assembly includes a sliding rod slidably connected to the movable frame and an actuating block fixed to the sliding rod.
[0009] Optionally, the actuating assembly further includes an actuating spring sleeved on the sliding rod, one end of the actuating spring being fixed to the sliding rod and the other end being fixed to the movable frame.
[0010] Optionally, a limiting rod is fixedly installed on the arc-shaped limiting plate, and a limiting groove is provided on the limiting rod.
[0011] Optionally, the limiting groove includes an inclined part and a horizontal part. One end of the inclined part is connected to the horizontal part. The inclined part gradually tilts outward in a direction away from the horizontal part. The horizontal part is located close to the feeding tray. The inclined part is located at the end of the horizontal part away from the feeding tray. The actuating spring pushes one end of the sliding rod to abut against the inner wall of the inclined part.
[0012] Optionally, a drive motor is provided on the frame, and the output shaft of the drive motor is connected to the rotating shaft.
[0013] In summary, this application includes at least one of the following beneficial technical effects:
[0014] 1. Under the action of gravity, the pipe in the hopper enters the discharge trough. Then the feeding plate rotates. During the rotation, the end of the discharge trough with pipe aligns with the feeding port. At this time, the pusher plate is moved by the pusher cylinder. The pusher plate pushes the pipe in the discharge trough to the feeding port. During the movement of the pipe, it is only subjected to horizontal force. Compared with the existing technology of clamping, this can reduce the deformation of the pipe.
[0015] 2. The moving cylinder drives the moving frame to move, and the moving frame drives the sliding rod and the actuating block to move towards the feeding plate. The sliding rod moves from the inclined part to the horizontal part, and the inner side of the actuating block abuts against the pipe surface. The end face of the actuating block abuts against the corrugated protrusion of the pipe, which will push the pipe completely away from the support shaft. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-5 This application will be described in further detail.
[0023] This application discloses an automatic pipe wave-making machine, including a frame 1 and a wave-making machine body 11 mounted on the frame 1. The wave-making machine body 11 is provided with a feed port 12 and a support shaft 13. The frame 1 is also provided with a feeding assembly 2, which is used to transport the pipe through the feed port 12 to the support shaft 13, thereby achieving the purpose of feeding.
[0024] The feeding assembly 2 includes a rotating shaft 21 fixed on the frame 1, a feeding tray 22 fixed on the rotating shaft 21, and an arc-shaped limiting plate 23 fixed on the frame 1. A feeding hopper 24 is provided on the arc-shaped limiting plate 23. Multiple discharge slots 25 are provided on the feeding tray 22, spaced circumferentially along the feeding tray 22. The arc-shaped limiting plate 23 is used to seal the openings of the discharge slots 25. Multiple unprocessed pipes are provided inside the feeding hopper 24. When the lower end of the feeding port corresponds to a discharge slot 25, the pipes inside the feeding hopper 24 will fall into the discharge slot 25 under gravity. To facilitate the rotation of the feeding tray 22, a drive motor is provided on the frame 1. The output shaft of the drive motor is connected to the rotating shaft 21, and the drive motor then drives the feeding tray 22 to rotate.
[0025] The end of the feeding trough 25 on the feeding tray 22 corresponds to the feeding port 12. The pipe in the feeding trough 25 is pushed into the wave machine body 11 through the feeding port 12 and finally sleeved on the support shaft 13, thereby achieving the purpose of automatic feeding. In order to facilitate the movement of the pipe in the feeding trough 25 into the wave machine body 11.
[0026] A pushing assembly 3 is provided on the frame 1. The pushing assembly 3 includes a pushing cylinder 31 and a pushing plate 32 fixed on the piston rod of the pushing cylinder 31. In this embodiment, the cross section of the pushing plate 32 is the same as the cross section of the feeding groove 25. The pushing cylinder 31 drives the pushing plate 32 to move. The pushing plate 32 moves into the feeding groove 25 and then pushes the pipe in the feeding groove 25 to move into the wave-making machine body 11 through the feed port 12. At this time, the pipe will be sleeved on the support shaft 13. The wave-making machine body 11 works to process the pipe on the support shaft 13 and then a corrugated structure is processed in the middle of the pipe.
[0027] During the processing, the main body 11 of the wave-making machine pushes the pipe on the support shaft 13 to move outward. Then, the pipe moves into the discharge trough 25 during the processing. After the processed pipe moves into the discharge trough 25, the feeding plate 22 rotates, and the unprocessed pipe above will correspond to the feeding port 12. Finally, the pushing component 3 pushes the pipe into the main body 11 of the wave-making machine, and the processed pipe will be at the bottom. Then, under the action of gravity, it will leave the discharge trough 25, thus achieving the purpose of automatic feeding.
[0028] Under the influence of gravity, the pipe in the hopper enters the discharge trough 25. Then, the feeding plate 22 rotates. During the rotation, the end of the discharge trough 25 with the pipe aligns with the feeding port. At this time, the push cylinder 31 drives the push plate 32 to move. The push plate 32 pushes the pipe in the discharge trough 25 to the feed inlet 12. During the movement of the pipe, it is only subjected to horizontal force. Compared with the gripper clamping technology of the prior art, this can reduce the deformation of the pipe.
[0029] A moving component 4 is provided on the frame 1, and a toggle component 5 is provided on the moving component 4. The toggle component 5 is used to toggle the pipe completely away from the support shaft 13. The moving component 4 is used to drive the toggle component 5 to reciprocate along the axis of the feeding tray 22. The moving component 4 includes a moving cylinder 41 fixed on the arc-shaped limiting plate 23 and a moving frame 42 fixed on the moving cylinder 41. The toggle component 5 is provided on the moving frame 42. The moving cylinder 41 drives the moving frame 42 to move, and the moving frame 42 drives the toggle component 5 to move, thereby pushing the pipe sleeved on the support shaft 13 to completely detach from the support shaft 13.
[0030] The actuating assembly 5 includes a sliding rod 51 slidably connected to the movable frame 42, an actuating block 52 fixed to the sliding rod 51, and an actuating spring 53 sleeved on the sliding rod 51. One end of the actuating spring 53 is fixed to the sliding rod 51, and the other end is fixed to the movable frame 42. A limiting rod 6 is fixedly installed on the arc-shaped limiting plate 23. A limiting groove 7 is provided on the limiting rod 6. The limiting groove 7 includes an inclined part 71 and a horizontal part 72. One end of the inclined part 71 is connected to the horizontal part 72. The inclined part 71 gradually tilts outward in a direction away from the horizontal part 72. The horizontal part 72 is located close to the feeding tray 22. The inclined part 71 is located at the end of the horizontal part 72 away from the feeding tray 22. The actuating spring 53 pushes one end of the sliding rod 51 to abut against the inner wall of the inclined part 71. In this embodiment, two limiting rods 6 are provided, and two actuating assemblies 5 are also provided.
[0031] As the moving cylinder 41 drives the moving frame 42 to move closer to the loading tray 22, the sliding rod 51 moves from the inclined part 71 to the horizontal part 72. Then, the actuating spring 53 pushes the actuating block 52 to move away from the limit rod 6. At this time, the two actuating blocks 52 move away from each other, and the distance between the two actuating blocks 52 becomes smaller. This causes the side of the actuating block 52 away from the sliding rod 51 to abut against the surface of the pipe, and the side of the actuating block 52 abuts against the raised corrugated part. Then, the processed pipe can be pushed into the discharge trough 25, which makes it easier for the pipe to detach from the support shaft 13.
[0032] In the initial state, the end of the sliding rod 51 is inside the inclined portion 71. The actuating spring 53 pushes the end face of the sliding rod 51 against the inner wall of the inclined portion 71. The distance between the two actuating blocks 52 is greater than the diameter of the pipe, which facilitates the pipe to pass through the gap between the two actuating blocks 52. After processing, the wave forming machine body 11 cannot completely push the pipe into the feeding trough 25. A part of the pipe is still sleeved on the support shaft 13. At this time, the feeding plate 22 cannot drive the pipe sleeved on the support shaft 13 to rotate. The actuating component 5 is needed to drive the pipe to completely detach.
[0033] When it is necessary to completely detach the pipe, the moving cylinder 41 drives the moving frame 42 to move, and the moving frame 42 drives the sliding rod 51 and the actuating block 52 to move towards the feeding tray 22. The sliding rod 51 moves from the inclined part 71 to the horizontal part 72, the inner side of the actuating block 52 abuts against the surface of the pipe, and the end face of the actuating block 52 abuts against the corrugated protrusion of the pipe, which will push the pipe to completely detach from the support shaft 13.
[0034] The implementation principle of an automatic pipe wave-making machine according to an embodiment of this application is as follows: the pipe in the feeding hopper 24 falls into the discharge trough 25 under the action of gravity, and then drives the feeding plate 22 to rotate, which drives the discharge trough 25 to rotate to the position corresponding to the feeding port. At this time, the push cylinder 31 drives the push plate 32 to move. The push plate 32 pushes the pipe in the discharge trough 25 to move completely into the wave-making machine body 11, and the pipe is sleeved on the support shaft 13. At this time, the wave-making machine body 11 processes the pipe. During the processing, the pipe will move into the discharge trough 25. The corrugated position will first move out from the feed port 12. Finally, the actuating component 5 drives the pipe to completely detach from the support shaft 13. With the rotation of the feeding plate 22, the processed pipe rotates to the bottom and then automatically detaches from the discharge trough 25 under the action of gravity, thereby achieving the purpose of automatic feeding.
