Abstract
Description
Technical Field
[0001] This invention relates to a pipe cutting technique, and more specifically, to a multi-head pipe cutting device. Background Technology
[0002] Currently, pipe fittings require pipe cutting during processing to break long pipes into multiple shorter ones before further processing. The conventional approach is to use one pipe cutting machine with one automated processing line. However, in actual processing, the cutting speed is much faster than the automated line, and the automated line's processing pace cannot keep up. Furthermore, each automated line requires its own pipe cutting machine, resulting in high equipment costs and increased floor space. Summary of the Invention
[0003] To overcome the above shortcomings, the present invention provides a multi-head pipe cutting device, which cuts and feeds the pipe into a multi-head processing line for subsequent processing, thereby reducing the investment in pipe cutting equipment and the floor space occupied by the processing line.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-head pipe cutting device, including a transfer trolley and a conveying mechanism. The transfer trolley is set near the unloading end of the conveying mechanism. The transfer trolley is correspondingly set with a slide rail. The transfer trolley is slidably installed on the slide rail. Multiple unloading stations are set on the slide rail. The transfer trolley moves to the unloading station to unload the material. Each unloading station is correspondingly set with a pipe processing line.
[0005] Long pipes are cut into short pipes to form fittings. The fittings are then transported to a transfer trolley via a conveyor mechanism. Once the number of fittings on the transfer trolley reaches a set value, the trolley moves to the unloading station and unloads the fittings onto the fitting processing line. Multiple unloading stations are set on the slide rails, allowing the transfer trolley to move to each station for unloading the fittings. This ensures that the cut fittings are transported to the multi-head processing line for further processing, reducing the investment in pipe cutting equipment and the floor space required for the processing line.
[0006] As a preferred option, the transfer trolley is equipped with a discharge port, and a liftable gate is installed at the discharge port.
[0007] After the pipe falls from the conveying mechanism onto the transfer trolley, the gate can block and position the pipe to prevent it from slipping off the transfer trolley. After the transfer trolley reaches the unloading station, the gate rises and the pipe automatically slides down onto the pipe processing line for subsequent processing under the action of gravity.
[0008] As a preferred option, a storage bin is installed on the transfer trolley, and the bottom of the storage bin is inclined.
[0009] The pipe fittings fall from the conveying mechanism into the storage bin of the transfer trolley. The bottom of the storage bin is inclined so that the pipe fittings can automatically slide onto the pipe fitting processing line when they are unloaded.
[0010] Preferably, a movable adjusting baffle is installed inside the storage silo, and the length of the storage silo is adjusted by moving the adjusting baffle.
[0011] The baffle is used to position the pipe along its length. The baffle is also movable, allowing for flexible and convenient adjustment based on the length of the pipe.
[0012] Preferably, a lifting stop bar is installed on the conveying mechanism, and the stop bar is positioned close to the transfer trolley.
[0013] The baffle bar positions and stops the pipe fittings as they are conveyed to it by the conveyor mechanism. Once the collected quantity reaches a set requirement, the baffle bar descends, and the pipe fittings fall onto the transfer trolley under gravity. Furthermore, because the transfer trolley needs to move to transport the pipe fittings, the baffle bar's positioning and stopping action ensures that the pipe fittings fall intermittently onto the trolley, preventing them from falling into empty spaces.
[0014] Preferably, the conveying mechanism includes an uphill section and a downhill section. The uphill section is equipped with an upward conveyor belt, and the downhill section is equipped with a bearing plate with the upper part of the bearing plate inclined downward.
[0015] The uphill conveyor belt transports the pipes upwards. After leaving the conveyor belt, the pipes fall onto the support plate, which supports them. The upper part of the support plate slopes downwards to facilitate the pipes sliding onto the transfer trolley during unloading.
[0016] Preferably, a feeding trough is provided on the conveying mechanism, the width of which matches the width of the conveying pipe, and the upper conveyor belt and the bearing plate are both placed in the feeding trough.
[0017] The feeding trough positions the pipe fittings to ensure stable transport.
[0018] Preferably, a deburring mechanism is provided at the feeding end of the conveying mechanism. A transmission belt and deburring rollers are installed on the deburring mechanism. The transmission belt conveys the pipe fittings, and the deburring rollers rotate to remove burrs from the ends of the pipe fittings.
[0019] Before entering the conveying mechanism, the pipe fittings pass through the deburring mechanism. The conveyor belt on the deburring mechanism transports the pipe fittings, and the deburring rollers rotate to remove the burrs from the ends of the pipe fittings.
[0020] Preferably, deburring rollers are installed on both sides of the transmission belt, a conveying groove is provided on the deburring mechanism, the transmission belt is installed in the conveying groove, and an avoidance window is provided on the side wall of the conveying groove, with the side wall of the deburring rollers exposed through the avoidance window.
[0021] The two deburring rollers have their sidewalls exposed by clearance windows on the two sidewalls of the conveying trough, allowing the two ends of the pipe fitting to contact and rub against the two deburring rollers to remove burrs. The pipe fitting can be deburred at both ends while being conveyed.
[0022] Preferably, both ends of the deburring roller are connected to mounting seats, which are slidably mounted on the deburring mechanism, and the ends of the deburring roller are rotatably connected to the mounting seats.
[0023] The mounting base is slidably adjusted to change the position, thereby adjusting the distance between the two deburring rollers to ensure reliable contact between the sidewall of the deburring roller and the end of the pipe fitting for deburring operation.
[0024] Compared with the prior art, the beneficial effects of the present invention are: (1) After the pipe is cut and fed into the multi-head processing line for subsequent processing, the investment in pipe cutting equipment and the floor space occupied by the processing line are reduced; (2) Before the pipe enters the conveying mechanism, the burrs at the end of the pipe are removed by the deburring mechanism. The deburring mechanism not only realizes the conveying of the pipe, but also realizes the deburring operation at the end of the pipe; (3) The baffle rod set on the conveying mechanism blocks and positions the pipe, so that the pipe falls intermittently onto the transfer trolley, avoiding the pipe falling into the air.

[0033] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:
[0034] Example 1: A multi-head pipe cutting device (see Figures 1 to 6 The system includes a transfer trolley 1 and a conveying mechanism 2. The transfer trolley 1 is located near the unloading end of the conveying mechanism 2. A storage bin 3 is installed on the transfer trolley 1, with an opening at the top and an inclined bottom. A discharge port is provided on the transfer trolley 1, and a liftable gate 4 is installed at the discharge port. The lower end of the gate 4 rests against the bottom surface of the storage bin 3, and the gate 4 is positioned at the lower part of the bottom surface of the storage bin 3. Guide seats 5 are installed at both ends of the gate 4. Two guide rails 6 are provided on the outer wall of the transfer trolley 1, and the guide rails 6 and guide seats 5 are arranged one-to-one. The guide seats 5 are slidably installed on the guide rails 6. An opening piston cylinder is installed on the transfer trolley 1, and the telescopic rod of the opening piston cylinder is connected to the gate 4. After the pipe fitting 55 falls from the conveying mechanism 2 onto the transfer trolley 1, the gate 4 can block and position the pipe fitting 55 to prevent it from slipping off the transfer trolley 1. After the transfer trolley 1 reaches the unloading station, the gate 4 rises, and the pipe fitting 55 automatically slides down onto the pipe fitting processing line 13 under the action of gravity for subsequent processing. The pipe fitting 55 falls from the conveying mechanism 2 into the storage bin 3 of the transfer trolley 1. The bottom of the storage bin 3 is inclined to facilitate the automatic sliding of the pipe fitting 55 onto the pipe fitting processing line 13 during unloading.
[0035] A movable adjusting baffle 7 is installed inside the storage silo 3, and the length of the storage silo 3 is adjusted by moving the adjusting baffle 7. An adjusting piston cylinder is installed on the transfer trolley 1, and the telescopic rod of the adjusting piston cylinder is connected to the adjusting baffle 7. A guide groove 8 is provided at the bottom of the storage silo 3. A guide post 9 and a connecting seat 10 are connected between the telescopic rod of the adjusting piston cylinder and the adjusting baffle 7. The guide post 9 passes through the guide groove 8 and is connected to the connecting seat 10. The guide post 9 is firmly connected to the adjusting baffle 7, and the connecting seat 10 is connected to the telescopic rod of the adjusting piston cylinder. Both the connecting seat 10 and the adjusting piston cylinder are located on the underside of the transfer trolley 1. Two guide rods 11 are provided at the bottom of the transfer trolley 1. The connecting seat 10 is movably inserted into the guide rods 11. During the adjustment and movement of the adjusting baffle 7, the connecting seat 10 slides along the guide rods 11, which is stable and reliable. The adjusting baffle 7 positions the pipe fitting 55 along its length, and the movable setting of the adjusting baffle 7 allows for flexible and convenient adjustment of the position of the adjusting baffle 7 according to the different lengths of the pipe fitting 55.
[0036] The transfer trolley 1 is equipped with a slide rail 12, and the transfer trolley 1 is slidably mounted on the slide rail 12. Multiple unloading stations are set on the slide rail 12. The transfer trolley 1 moves to the unloading station to unload materials. Each unloading station corresponds to a pipe fitting processing line 13. A rack 14 is installed on the slide rail 12, and a transverse motor is installed on the transfer trolley 1. A gear 15 is installed on the output shaft of the transverse motor, and the gear 15 meshes with the rack 14 for transmission. The rotation of the transverse motor causes the gear 15 to mesh with the rack 14, thereby realizing the movement of the transfer trolley 1. By controlling the number of rotations of the transverse motor, the transfer trolley 1 can accurately reach the unloading station. Several linear slides 16 and several support wheels 17 are set at the bottom of the transfer trolley 1. The linear slides 16 are adapted to slide and slidably connected to the slide rail 12. A support beam 18 is set below the transfer trolley 1, and the support wheels 17 are supported on the support beam 18. A support frame is correspondingly set on the transfer trolley 1, and both the slide rail 12 and the support beam 18 are mounted on the support frame.
[0037] Two lifting baffles 19 are installed on the conveying mechanism 2, positioned close to the transfer trolley 1. These baffles 19 block and position the pipe fitting 55. The baffles 19 are connected to a telescopic piston cylinder rod, which moves up and down to move the baffles 19. The pipe fitting 55 is conveyed on the conveying mechanism 2 to the baffles 19 for collection. When the collected quantity reaches a set requirement, the baffles 19 descend, and the pipe fitting 55 falls onto the transfer trolley 1 under gravity. Furthermore, because the transfer trolley 1 needs to move to convey the pipe fitting 55, the baffles 19 block and position the pipe fitting 55, ensuring that the pipe fitting 55 falls intermittently onto the transfer trolley 1, preventing it from falling into empty spaces.
[0038] The conveying mechanism 2 includes an uphill section 20 and a downhill section 21. The uphill section 20 is equipped with an upward conveyor belt, and the downhill section 21 has two support plates 23 arranged opposite each other, with the upper part of each support plate 23 inclined downwards. A baffle bar 19 is located on the upper part of the support plate 23 near its lower side. The upward conveyor belt is inclined and includes two oppositely arranged conveyor chains 24 and several conveyor plates 25 connected between the two conveyor chains 24. The conveyor plates 25 are spaced apart and have an L-shaped structure. Pipe fittings 55 support the conveyor plates 25 for conveying. The upper and lower parts of the uphill section 20 are respectively equipped with an upper sprocket and a lower sprocket. The conveyor chains 24 are driven between the upper and lower sprockets, which are driven by a motor.
[0039] A feeding trough 26 is provided on the conveying mechanism 2. The width of the feeding trough 26 matches the width of the conveying pipe 55. The upward conveyor belt and the support plate 23 are both placed in the feeding trough 26. The lower part of the support plate extends below the upward conveyor belt to form a feeding section. The pipe 55 is supported on the feeding section and is fed from below the upward conveyor belt onto the upward conveyor belt. The width of the feeding trough 26 is adjustable to accommodate the conveying of pipes 55 of different lengths.
[0040] The conveying mechanism 2 includes a fixed vertical plate 27 and a movable vertical plate 28. The feeding trough 26 is disposed between the fixed vertical plate 27 and the movable vertical plate 28. The movable vertical plate 28 is movable. The distance between the fixed vertical plate 27 and the movable vertical plate 28 can be adjusted by adjusting the position of the movable vertical plate 28, thereby adjusting the width of the feeding trough 26.
[0041] A deburring mechanism 22 is provided at the feeding end of the conveying mechanism 2. A drive belt and deburring rollers 29 are installed on the deburring mechanism 22. The drive belt conveys the pipe fitting 55, and the deburring rollers 29 rotate to remove burrs from the end of the pipe fitting 55. The drive belt includes two oppositely arranged drive chains 30 and a number of limiting blocks 31 spaced apart on the drive chains 30. A feeding groove 32 is formed between two adjacent limiting blocks 31. The width of the feeding groove 32 gradually decreases in the opening direction. The two ends of the pipe fitting 55 are respectively loaded into the two feeding grooves 32 for conveying.
[0042] The transmission belt is driven by a motor. Deburring rollers 29 are installed on both sides of the transmission belt. A flipping strip 33 is provided on the deburring mechanism corresponding to the deburring rollers 29. Several flipping grooves 34 are spaced apart on the flipping strip 33. One side of each flipping groove 34 is inclined to form a pushing surface 35. During the conveying process, the outer wall of the pipe 55 abuts against the pushing surface 35 to achieve flipping and posture adjustment. This flipping and posture adjustment ensures that all positions of the end edge can contact the side wall of the deburring rollers 29 for deburring, ensuring the deburring effect at the end of the pipe 55. A positioning stop is provided on the deburring mechanism corresponding to the deburring rollers 29. The positioning stop is positioned above the end of the pipe 55 to prevent burrs from flying outwards during the deburring process. The flipping strip 33 is placed outside the transmission chain 30, and the pipe 55 is placed between the flipping strip 33 and the positioning stop.
[0043] The deburring mechanism 22 is provided with a conveying groove 36, in which a transmission belt is installed. A clearance window is provided on the side wall of the conveying groove 36, and the side wall of the deburring roller 29 protrudes from the clearance window. Both ends of the deburring roller 29 are connected to mounting seats 37, which are slidably mounted on the deburring mechanism 22. The ends of the deburring roller 29 are rotatably connected to the mounting seats 37. Corresponding sliding grooves are provided on the deburring mechanism 22 and the mounting seats 37. The mounting seats 37 are installed in the sliding grooves and are movable. Locking screws connect the mounting seats 37 and the deburring assembly, positioning the mounting seats 37. A deburring motor 38 is mounted on the deburring mechanism 22. A driven pulley is mounted on the end of the deburring roller 29, and a driving pulley is mounted on the output shaft of the deburring motor 38. A belt drive connects the driving pulley and the driven pulley.
[0044] The width of the conveying trough 36 is adjustable to accommodate pipe fittings 55 of different lengths. The deburring mechanism 22 includes a fixed frame 39 and a movable frame 40. Two deburring rollers 29 are respectively mounted on the fixed frame 39 and the movable frame 40. The conveying trough 36 is positioned between the fixed frame 39 and the movable frame 40. The width of the conveying trough 36 is adjusted by adjusting the distance between the fixed frame 39 and the movable frame 40. A receiving frame 41 is provided at one end of the deburring mechanism 22. A support inclined plate 42 is installed on the receiving frame 41. The pipe fitting 55 slides down from the support inclined plate 42 onto the transmission belt for conveying.
[0045] Long pipes are cut into short pipes to form pipe fittings 55. Pipe fittings 55 first pass through a deburring mechanism 22, where a transmission belt conveys them. Deburring rollers 29 rotate to remove burrs from the ends of pipe fittings 55. Then, they are conveyed to a transfer trolley 1 via a conveying mechanism 2. When the number of pipe fittings 55 on the transfer trolley 1 reaches a set value, the transfer trolley 1 moves to the unloading station and unloads the pipe fittings 55 onto the pipe fitting processing line 13. Multiple unloading stations are set on the slide rail 12, allowing the transfer trolley 1 to move to each unloading station to unload the pipe fittings 55. This ensures that the cut pipes are conveyed to the multi-head processing line for subsequent processing, reducing the investment in pipe cutting equipment and the floor space occupied by the processing line.
[0046] Example 2: A multi-head pipe cutting device (see Figures 1 to 7 The system includes a transfer trolley 1 and a conveying mechanism 2.

The width of the conveying trough 36 is adjusted by adjusting the distance between the fixed frame 39 and the movable frame 40. A receiving frame 41 is provided at one end of the deburring mechanism 22. A support inclined plate 42 is installed on the receiving frame 41. The pipe fitting 55 slides down from the support inclined plate 42 onto the transmission belt for conveying.
[0057] The feeding end of the conveying mechanism 2 is provided with a feeding mechanism 43, which includes a base plate 44, a clamping plate 45, and a push rod 46. The base plate 44 and the clamping plate 45 are both inclined and the upper parts of the base plate 44 and the clamping plate 45 are rotatably installed. The clamping plate 45 is located near the lower part of the base plate 44, and a stop bar 47 is located near the upper part of the clamping plate 45. Several conveying plates 25 are arranged at intervals on the upward conveyor belt. The push rod 46 is slidably arranged. The base plate 44 and the clamping plate 45 are both pressed against the push rod 46. The conveying plates 25 push the push rod 46 to slide as the upward conveyor belt runs. The push rod 46 pushes the base plate 44 and the clamping plate 45, increasing the distance between the base plate 44 and the clamping plate 45. The pipe 55 between the base plate 44 and the clamping plate 45 falls onto the conveying plate 25.
[0058] A support column 48 is installed below the base plate 44 to support the base plate 44. A positioning spring 49 connects the base plate 44 and the support column 48. A positioning torsion spring is installed at the rotatable connection of the upper part of the clamping plate 45. A limit rod 50 is installed on the stop rod 47, and a positioning rod 51 is installed on the clamping plate 45. The positioning rod 51 abuts against the limit rod 50 to achieve positioning of the clamping plate 45. Side plates are provided on both sides of the feeding mechanism 43. The base plate 44 and the clamping plate 45 are rotatably installed between the side plates. A positioning groove 52 is provided on the side plate. The push rod 46 is adapted to slide and connect with the positioning groove 52. The push rod 46 is inclined. A contact head 53 is provided at the lower end of the push rod 46. The upper end of the push rod 46 abuts against the lower surface of the clamping plate 45. An abutting post 54 is provided on the push rod 46 and abuts against the lower surface of the base plate 44. The positioning torsion spring is installed between the side plate and the clamping plate 45. The distance between the base plate 44 and the clamping plate 45 gradually decreases from top to bottom. The distance between the lower ends of the base plate 44 and the clamping plate 45 is less than the outer diameter of the pipe fitting 55, thereby achieving the positioning of the pipe fitting 55. The distance between the upper end of the push rod 46 and the upper rotating mounting point of the clamping plate 45 is less than the distance between the abutment column 54 and the upper rotating mounting point of the base plate 44. The distance that the push rod 46 pushes the clamping plate 45 upward is greater than the distance that the push rod 46 pushes the base plate 44 upward, thereby increasing the distance between the lower ends of the base plate 44 and the clamping plate 45, allowing the pipe fitting 55 to slide onto the conveyor plate 25.
[0059] The conveyor plate 25 abuts against the contact head 53 at the lower end of the push rod 46. At this time, the conveyor plate 25 is placed below the base plate 44 and is in an unloaded state. As the base plate 44 and the clamping plate 45 are pushed, the distance between the lower ends of the base plate 44 and the clamping plate 45 increases, and the conveyor plate 25 approaches the opening between the lower ends of the base plate 44 and the clamping plate 45. At this time, the pipe fitting 55 can automatically slide down onto the conveyor plate 25 for conveying.
[0060] During the operation of the upward conveyor belt, the push rod 46 continuously pushes the base plate 44 and clamping plate 45 to rotate, enabling automatic material handling of the pipe fittings 55 loaded on the base plate 44 and preventing blockages during the conveying process. Furthermore, the distance between the lower ends of the base plate 44 and clamping plate 45 is less than the outer diameter of the pipe fitting 55, thus positioning the pipe fitting 55 until the conveyor plate 25 approaches the opening between the lower ends of the base plate 44 and clamping plate 45, at which point the pipe fitting 55 slides down, preventing it from clustering together and causing chaotic or even jammed conveying.
[0061] Long pipes are cut into short pipes to form pipe fittings 55. Pipe fittings 55 first pass through a deburring mechanism 22, where a transmission belt conveys them. Deburring rollers 29 rotate to remove burrs from the ends of pipe fittings 55. After deburring, pipe fittings 55 fall onto the base plate 44 of the loading mechanism 43, and then are conveyed to the transfer trolley 1 via the conveying mechanism 2. When the number of pipe fittings 55 on the transfer trolley 1 reaches a set value, the transfer trolley 1 moves to the unloading station and unloads the pipe fittings 55 onto the pipe fitting processing line 13. Multiple unloading stations are set on the slide rail 12, allowing the transfer trolley 1 to move to each unloading station to unload the pipe fittings 55. This ensures that the cut pipes are conveyed to the multi-head processing line for subsequent processing, reducing the investment in pipe cutting equipment and the floor space occupied by the processing line.
[0062] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
