Description

Technical Field

[0001] This utility model relates to the field of pipe cutting machine technology, specifically to a receiving device for an automatic pipe cutting machine. Background Technology

[0002] Metal pipes need to be cut according to their length during use. Existing pipe cutting machines cut metal pipes, and the cut pipes fall directly onto a receiving box or conveyor belt for the next process. This receiving method makes it easy for the pipes to break or shatter when they fall, resulting in a high scrap rate and unnecessary losses. To address this, we have proposed a receiving device for an automatic pipe cutting machine. Utility Model Content

[0003] This invention provides a receiving device for an automatic pipe cutter, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a receiving device for an automatic pipe cutter, comprising opposing receiving side frames, with self-retractable telescopic support legs rotatably connected to the bottom of both ends of the receiving side frames, a receiving cloth provided between the receiving side frames, and a winding assembly provided inside the receiving side frames, wherein the receiving cloth extends into the interior of the receiving side frames on both sides and is connected to the winding assembly. An internal support assembly is provided between the receiving side frames at the bottom of the receiving cloth; One end of the receiving side frame is rotatably connected to an adjusting auxiliary frame. The inner side of the adjusting auxiliary frame is slidably connected to a receiving baffle. The receiving baffle is provided with a buffer pad on the side near the receiving cloth. The pipe can slide down from the receiving cloth to contact the receiving baffle and be fed from between the adjusting auxiliary frames.

[0005] Preferably, the middle of the receiving side frame is axially through, and end caps are bolted to both ends of the receiving side frame; The winding assembly includes a torsion spring and a spool; A roller is rotatably connected to the middle of the inner side of the end cap, and the side of the receiving cloth is installed on the outside of the roller, and the receiving cloth can be stored in the receiving side frame. The two ends of the reel are fitted with torsion springs, and the other end of the torsion spring is fitted into the end cap.

[0006] Preferably, the telescopic outrigger includes a main leg arm and a telescopic arm; One end of the main leg arm is rotatably connected to the receiving side frame; The other end of the main leg arm is slidably connected to a telescopic arm, which extends into the interior of the main leg arm.

[0007] Preferably, the telescopic outrigger further includes positioning bolts; An internal threaded hole is provided on the outer side of the other end of the main leg arm; The telescopic arm has a row of positioning holes on one side, which can intersect with the internal threaded holes; The positioning bolt is threaded into the internal threaded hole and inserted into the positioning hole.

[0008] Preferably, the inner side of the receiving side frame is provided with a linear slide groove, and a bidirectional threaded rod is rotatably connected in the linear slide groove. Opposite sliders are slidably connected in the linear slide groove, and the sliders are respectively threaded to both ends of the bidirectional threaded rod. An inner support rod is rotatably connected to the slider, and a connecting block is rotatably connected to the ends of the inner support rod.

[0009] Preferably, the adjusting bracket includes a side plate, a connecting plate, and a threaded post; The side plates are rotatably connected to the outer side of the receiving side frame end, and the receiving baffle is slidably connected to the side plates. The connecting plate is equipped with threaded posts at both ends, and the two ends of the threaded posts pass through the two side plates respectively, and nuts located on both sides of the side plates are threaded onto the threaded posts.

[0010] Preferably, an electric push rod is installed in the middle of the outer side of the connecting plate, and the output end of the electric push rod passes through the connecting plate and is connected to the receiving baffle.

[0011] This utility model has the following beneficial effects: 1. The receiving device of this automatic pipe cutter uses a flexible receiving cloth as the main load-bearing body and a torsion spring-driven winding assembly to keep it at a moderate tension, providing an effective first buffer layer for the falling pipe, greatly absorbing the vertical impact energy. At the same time, the telescopic support legs located at the bottom of the receiving side frame can be flexibly adjusted to make the receiving cloth form an arc-shaped slope that smoothly transitions from the high end (closer to the pipe cutter) to the low end (closer to the discharge port). After the pipe contacts the receiving cloth, part of its kinetic energy is converted into potential energy changes as it slides down the slope, further reducing the impact. The pipe that slides to the end finally makes soft contact with the receiving baffle with a cushioning pad (such as rubber, silicone, polyurethane, etc.), which is the third layer of buffering. This multi-level buffering mechanism of "flexible support - slope buffering - soft blocking" weakens the collision force between the pipe and the receiving device layer by layer, effectively protecting the integrity of the pipe and significantly reducing material waste and production costs.

[0012] 2. The receiving device for this automatic pipe cutter, through its telescopic and rotatable outriggers, allows for convenient adjustment of the overall height and the tilt angle of the receiving cloth plane. This enables precise docking with the discharge ports of different pipe cutter models and optimizes the pipe's sliding angle. The internal support assembly, driven by a bidirectional threaded rod, precisely adjusts the unfolded length of the receiving cloth in the middle to accommodate pipes of different weights (lightweight pipes require a gentle slope to prevent splashing, while heavy pipes require a steep slope to facilitate sliding) and lengths (long pipes require a larger support surface). The overall width, tilt angle, and height of the receiving baffle of the adjustable auxiliary frame can all be adjusted independently, and the position of the baffle is automatically controlled via an electric push rod. This all-round, multi-degree-of-freedom adjustable design allows the device to be widely used in cutting and receiving scenarios for various materials and specifications of pipes, such as metal pipes, glass pipes, and plastic pipes. It is highly versatile and flexible in integrated deployment. Attached Figure Description

[0015] 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.

[0016] Please see Figures 1 to 8 A receiving device for an automatic pipe cutter includes opposite receiving side frames 1, with self-retractable telescopic support legs 3 rotatably connected to the bottom of both ends of the receiving side frames 1, receiving cloth 2 between the receiving side frames 1, and a winding assembly 8 inside the receiving side frames 1. The receiving cloth 2 extends into the receiving side frames 1 on both sides and is connected to the winding assembly 8. An inner support assembly 7 is provided at the bottom of the receiving cloth 2 between the receiving side frame 1; One end of the receiving side frame 1 is rotatably connected to an adjusting auxiliary frame 5. The inner side of the adjusting auxiliary frame 5 is slidably connected to a receiving baffle 4. The receiving baffle 4 is provided with a buffer pad on the side near the receiving cloth 2. The pipe can slide down from the receiving cloth 2 to contact the receiving baffle 4 and be discharged from between the adjusting auxiliary frames 5.

[0017] This utility model adopts a dual buffer structure of receiving cloth 2 for receiving and buffer pad for protection. The elastic material of receiving cloth 2 and the silicone material of buffer pad can effectively absorb the impact of falling pipe. In addition, the anti-slip convex strip slows down the falling speed. The height adjustment of telescopic support leg 3 can be adapted to automatic pipe cutting machines of different heights. The receiving cloth 2 can adjust the receiving width through the winding component 8, and the inner support component 7 supports the receiving side frame 1 after the width is adjusted.

[0018] Please see Figures 1 to 8 The middle of the receiving side frame 1 is axially through, and end caps 11 are bolted to both ends of the receiving side frame 1. The winding assembly 8 includes a torsion spring 81 and a reel 82; A roller 82 is rotatably connected to the middle of the inner side of the end cap 11. The side of the receiving cloth 2 is installed on the outside of the roller 82, and the receiving cloth 2 can be stored in the receiving side frame 1. Torsion springs 81 are inserted at both ends of the roller 82, and the other end of the torsion spring 81 is inserted into the end cover 11. The torsion spring 81 provides a continuous torsional torque to the roller, so that the receiving cloth is always in a taut state and the receiving surface is flat. When it is necessary to replace or clean the receiving cloth, the receiving cloth 2 can be pulled out by overcoming the force of the torsion spring 81. After being released, the torsion spring 81 can automatically roll it back and store it, which is convenient to operate.

[0019] Please see Figures 1 to 8 The telescopic outrigger 3 includes a main leg arm 31 and a telescopic arm 32; One end of the main leg arm 31 is rotatably connected to the receiving side frame 1; The other end of the main leg arm 31 is slidably connected to a telescopic arm 32, which extends into the interior of the main leg arm 31. By sliding the telescopic arm 32 within the main leg arm 31, the length of the telescopic support leg 3 of the entire device can be adjusted, thereby changing the overall height of the device to match the height of the discharge port of different cutting machines or the height requirements of different feeding conveyor lines. The rotatable connection between the main leg arm 31 and the receiving side frame 1 allows the telescopic support leg 3 to switch between retracted (close to the side frame) and extended (supported state), and also facilitates adjustment of the tilt angle of the receiving cloth.

[0020] Please see Figures 1 to 8 The telescopic outrigger 3 also includes a positioning bolt 33; An internal threaded hole 311 is provided on the outer side of the other end of the main leg arm 31; The telescopic arm 32 has a row of positioning holes 321 on one side, which can intersect with the internal threaded holes 311; The positioning bolt 33 is threaded into the internal threaded hole 311 and inserted into the positioning hole 321. When the telescopic arm 32 is stretched to the required length and a positioning hole 321 is aligned with the internal threaded hole 311, the positioning bolt 33 can be screwed in to lock the telescopic arm 32. The structure is simple and reliable, easy to adjust and low in cost.

[0021] Please see Figures 1 to 8 A linear slide groove is provided on the inner side of the receiving side frame 1, and a bidirectional threaded rod 71 is rotatably connected in the linear slide groove. Opposite sliders 72 are slidably connected in the linear slide groove, and the sliders 72 are respectively threaded to both ends of the bidirectional threaded rod 71. An inner support rod 73 is rotatably connected to the slider 72. A connecting block 74 is rotatably connected to the ends of the inner support rod 73. Rotating the bidirectional threaded rod 71 can make the two sliders 72 move synchronously towards or away from each other, thereby pushing or pulling the connecting block 74 through the inner support rod 73. When the connecting block 74 moves, it lifts the receiving side frame 1 through the inner support rod 73, which can adjust the length of the receiving cloth 2 to adapt to different pipe lengths and form an overall structure that is easy to store.

[0022] Please see Figures 1 to 8 The adjusting bracket 5 includes a side plate 51, a connecting plate 52, and a threaded column 53; The side plates 51 are rotatably connected to the outer side of the receiving side frame 1, and the receiving baffle 4 is slidably connected to the side plate 51. Threaded posts 53 are installed at both ends of the connecting plate 52. The two ends of the threaded posts 53 pass through the two side plates 51 respectively, and nuts are threaded onto the threaded posts 53 on both sides of the side plates 51 respectively. The adjusting bracket 5 can rotate as a whole around its connecting shaft with the receiving side bracket 1 to change the tilt angle of the receiving baffle. Loosening the nuts allows the side plates 51 to move along the threaded posts 53, thereby adjusting the width of the two side plates 51 (i.e. the entire adjusting bracket) to accommodate pipes of different lengths. The receiving baffle 4 can slide along the side plates 51 to change its distance from the end of the receiving cloth 1 (discharge port) and control the end position of the pipe's sliding stroke.

[0023] Please see Figures 1 to 8 An electric push rod 6 is installed in the middle of the outer side of the connecting plate 52. The output end of the electric push rod 6 passes through the connecting plate 52 and is connected to the receiving baffle 4. The electric push rod 6 can precisely drive the receiving baffle 4 to slide up and down along the side plate 51 to realize the adjustment of the position of the receiving baffle 4. The baffle 4 rhythm can be automatically adjusted according to the pipe length or the feeding rhythm.

[0024] In summary, the receiving device of this automatic pipe cutter works as follows: when the cut pipe falls from the outlet, it first lands on the receiving cloth 2, which has a certain tension and elasticity, and the impact is largely absorbed. Subsequently, the pipe slides downward along the inclined surface formed by the receiving cloth 2 (towards the adjusting bracket 5). During the sliding process, the material of the receiving cloth 2 (such as high-strength canvas, nylon cloth, or fabric with anti-slip coating) can provide moderate friction, control the sliding speed, and prevent the pipes from colliding with each other due to excessive speed or generating secondary impact at the end. After the pipe slides to the end of the receiving cloth 2, it comes into contact with the buffer pad (such as a rubber strip or silicone pad attached to the baffle) on the receiving baffle 4 at a low speed. The impact force is further dissolved, and the pipe temporarily stays in the area enclosed by the end of the receiving cloth 2, the side plates 51 on both sides, and the receiving baffle 4. When the pipe fitting is ready for the next process, or when it needs to be released according to the production rhythm, the control system (which can be linked with the pipe cutter) starts the electric push rod 6 to lift the receiving baffle 4 obliquely upward. After the baffle is lifted, the pipe fitting is no longer obstructed and slides out orderly from below the adjusting bracket 5 (the space between the two side plates 51) under the action of gravity, falling into the collection box, conveyor belt or designated station below, completing a receiving and unloading cycle.
