Description

Technical Field

[0001] This invention relates to the field of steel pipe processing equipment technology, and in particular to a short pipe processing production line. Background Technology

[0002] Currently, the demand for steel pipes of various lengths and specifications is increasing in the machinery manufacturing industry, especially in some precision instruments and mechanical equipment, where the demand for short pipes (i.e., those less than 500mm in length) is particularly evident.

[0003] During the production and processing of short pipes, long steel pipes are usually cut into short pipes of fixed length using a cutting device. Then, the operator takes the cut short pipes and places them in the chamfering station. The chamfering device is used to chamfer both ends of the short pipes. After the chamfering is completed, the operator takes the short pipes and places them in the chip removal station. The chip removal device removes the iron filings generated during the chamfering process from the inside of the short pipes. After the chip removal is completed, the operator takes the short pipes and places them in the degreasing station. The degreasing device removes the oil stains from both ends of the short pipes.

[0004] In the existing production and processing of short pipes, the transfer and placement of short pipes between different processing steps requires the participation of operators. As a result, the efficiency of the transfer and placement of short pipes between different processing steps is affected by the operators, which in turn affects the production and processing efficiency of short pipes. Summary of the Invention

[0005] In order to achieve automated transfer of short tubes between different processing steps, thereby improving the transfer efficiency of short tubes between different processing steps and thus improving the production efficiency of short tubes, this application provides a short tube processing production line.

[0006] This application provides a short pipe processing production line, which adopts the following technical solution: A short pipe processing production line includes a cutting device. A first conveyor is arranged on one side of the cutting device, a buffer device is arranged on one side of the first conveyor, and a material transfer mechanism is arranged on the other side of the first conveyor. An intermittent conveying device is arranged on the side of the buffer device away from the first conveyor. A chamfering device and a preliminary cleaning device are arranged sequentially on both sides of the intermittent conveying device along the conveying direction. A second conveyor is arranged on the side of the intermittent conveying device away from the buffer device. A mounting frame is arranged on one side of the second conveyor, and a feeding assembly is arranged on the mounting frame. A transfer assembly is arranged on the other side of the second conveyor. A secondary cleaning device and a length measuring device are arranged sequentially on the mounting frame along the feeding direction. A receiving device is arranged at one end of the mounting frame.

[0007] By adopting the above technical solution, the use of conveyor one in conjunction with the material transfer mechanism helps to transport the cut short pipes to the buffer device for temporary storage; the use of the intermittent conveying device helps to sequentially and intermittently transport the short pipes stored in the buffer device to the processing positions of the chamfering device and the preliminary cleaning device for chamfering and preliminary cleaning; the use of conveyor two in conjunction with the transfer assembly helps to transfer the chamfered and preliminary cleaned short pipes to the feeding assembly of the mounting frame; the feeding assembly helps to sequentially and intermittently transport the short pipes to the processing positions of the secondary cleaning device and the length measuring device for secondary cleaning and length measurement; and the use of the receiving device helps to separately collect and store short pipes that pass the length measurement and those that fail. This application helps to realize the automated transfer of short pipes between different processing steps, thereby helping to improve the transfer efficiency of short pipes between different processing steps, and thus helping to improve the production and processing efficiency of short pipes.

[0008] In one specific implementation scheme, the buffer device includes a fixed frame, on which buffer frame one and buffer frame two are sequentially arranged along the direction away from conveyor one. Buffer frame one and buffer frame two are both inclined. The bottom end of buffer frame one is adjacent to the top end of buffer frame two, and the bottom end of buffer frame one is lower than the top end of buffer frame two. A stop block is provided at the bottom end of buffer frame two. A lifting mechanism is provided on the fixed frame. The lifting mechanism is used to lift the short pipe located at the bottom end of buffer frame one onto buffer frame two with the cooperation of the intermittent conveying device.

[0009] By adopting the above technical solution, the use of buffer rack one and buffer rack two helps to store short pipes in sections. The use of the top material mechanism in conjunction with the intermittent conveying device helps to lift and transfer the short pipes at the bottom of buffer rack one to buffer rack two. This helps to automatically transport the short pipes at the bottom of buffer rack two to the processing positions of the chamfering device and the preliminary cleaning device for chamfering and preliminary cleaning.

[0010] In one specific implementation scheme, the intermittent conveying device includes a feeding rack with several sets of feeding troughs spaced apart on its top. A trough frame is installed inside the feeding rack. Guide rails are horizontally arranged on opposite side walls of the trough frame. Movable blocks are engaged within the guide rails. A slide rail is vertically arranged on the side wall of the movable block, and a slider is engaged on the slide rail. An mounting block is fixedly connected to the slider. A conveying plate is installed on the top of the mounting block, and several material clamping slots are spaced apart on its top. An mounting rod is installed at the bottom of the mounting block, and a connecting column is installed at the end of the mounting rod furthest from the mounting block. A dual-head motor is installed inside the trough frame, with both output ends of the dual-head motor penetrating the side walls of the trough frame. A rotating plate is installed on each output end of the dual-head motor, and an oblong hole is provided on the rotating plate. The connecting column is inserted and engaged within the oblong hole. Movable rails for the connecting column to be engaged are provided on the side walls of the trough frame.

[0011] By adopting the above technical solution, the dual-head motor helps to drive the two rotating plates to rotate, which in turn helps to drive the connecting column to move along the trajectory of the movable track, and in turn helps to drive the mounting block to move synchronously through the mounting rod. At the same time, the sliding of the movable block in the guide rail and the sliding of the slider on the slide rail help to guide the movement trajectory of the mounting block, so that the mounting block drives the conveying plate to reciprocate along the shape trajectory of the movable track. This helps the conveying plate to automatically transport the short tubes at the bottom of the buffer rack two to a set of feeding troughs near the fixed frame during the movement, and at the same time transfer the short tubes placed in each set of feeding troughs to the next set of feeding troughs, until the short tubes in the last set of feeding troughs are transferred to the conveyor two for conveying.

[0012] In one specific implementation scheme, the top material mechanism includes a movable block and two columns spaced apart within a fixed frame. The movable block has two elongated holes spaced apart, and each column is located within one of these holes. The movable block has an arc-shaped concave surface. A top plate is commonly mounted on the two columns. A lifting rod is slidably mounted on the top plate. A base plate is mounted at the bottom end of the lifting rod. Rollers are mounted on the bottom surface of the base plate, and these rollers roll against the arc-shaped concave surface. A return spring is circumferentially fitted onto the lifting rod, with one end connected to the base plate and the other end connected to the top plate. A top material plate is inclinedly mounted at the top of the lifting rod, and the height of the top surface of the top material plate gradually decreases along the direction from the first buffer frame towards the second buffer frame. The movable block is equipped with a connecting component for transmission with the conveyor plate.

[0013] By adopting the above technical solution, during the movement of the conveyor plate, the connecting components help to move the moving block, which in turn helps to lift the lifting rod and the top plate by the relative displacement of the rollers on the arc concave surface. This, in turn, helps to lift and transfer the short pipe at the bottom of the first buffer rack to the second buffer rack by using the inclined top plate. This facilitates the automatic conveyor plate to transport the short pipe blocked at the bottom of the second buffer rack to the processing position of the chamfering device and the preliminary cleaning device for chamfering and preliminary cleaning.

[0014] In one specific implementation scheme, a connecting rod is provided between the two conveying plates. The connecting assembly includes a connecting rod, a connecting block, a transmission rod, and a transmission column. One end of the connecting rod is connected to the moving block. The connecting block is located at the end of the connecting rod away from the moving block. One end of the transmission rod is connected to the connecting rod. The transmission column is located at the end of the transmission rod away from the connecting rod. The connecting block is provided with a snap-fit ​​groove. The transmission column is vertically and vertically snap-fitted into the snap-fit ​​groove.

[0015] By adopting the above technical solution, during the movement of the conveyor plate, it helps to drive the connecting rod to move synchronously. The movement of the connecting rod helps to drive the transmission rod to move synchronously, which in turn helps to drive the connecting rod to move horizontally through the cooperation between the transmission column and the connecting block. This, in turn, helps to drive the moving block to move horizontally. It also helps to drive the lifting rod and the top plate to rise through the relative displacement of the rollers on the arc concave surface. It also helps to use the inclined top plate to lift and transfer the short pipe at the bottom of the first buffer frame to the second buffer frame. Finally, it facilitates the automatic conveyor plate to transport the short pipe blocked at the bottom of the second buffer frame to the processing position of the chamfering device and the preliminary cleaning device for chamfering and preliminary cleaning.

[0016] In one specific implementation scheme, the material transfer mechanism includes a mounting bracket disposed on the side of the conveyor away from the buffer device. A linear slide is mounted on the mounting bracket, and a vertical rod is mounted on the movable end of the linear slide. A vertical groove is provided on the side wall of the vertical rod facing the conveyor, and a lifting block is slidably engaged within the vertical groove. A drive motor is mounted on the top of the vertical rod, and a screw is mounted on the output end of the drive motor. The screw is threadedly connected to the lifting block. A mounting plate is mounted on the side wall of the lifting block, and a material transfer baffle is mounted on the side of the mounting plate away from the lifting block. A material transfer baffle is provided with a material gripping assembly for gripping the short pipes conveyed on the conveyor.

[0017] By adopting the above technical solution, the linear slide table helps to drive the upright to move horizontally, which in turn helps to drive the material transfer baffle to move horizontally through the lifting block and the mounting plate; the drive motor helps to drive the screw to rotate, which in turn helps to drive the lifting block to move up and down, which in turn helps to drive the material transfer baffle to move up and down through the mounting plate; the gripping assembly helps to grip the short pipes conveyed on the conveyor, which helps to place the gripped short pipes on the buffer device for temporary storage in conjunction with the operation of the linear slide table and the drive motor.

[0018] In one specific implementation scheme, the material gripping assembly includes a mounting frame, a drive cylinder, a plug-in post, and a material gripping clamp. The mounting frame is disposed on the side wall of the material transfer baffle, the drive cylinder is disposed on the mounting frame, the plug-in post is disposed on the piston rod of the drive cylinder, a guide portion is provided at the end of the plug-in post away from the drive cylinder, the material gripping clamp is disposed at the end of the plug-in post near the drive cylinder, and the material transfer baffle is provided with a clearance opening for the plug-in post and the material gripping clamp to pass through.

[0019] By adopting the above technical solution, the driving cylinder helps to drive the insertion post and the gripping clamp to pass through the clearance opening, the guide helps to guide the insertion post to be inserted into the short tube, and the gripping clamp, in conjunction with the insertion post, helps to clamp the short tube, thereby facilitating the gripping of the short tube and making it convenient to place the gripped short tube on the buffer device for temporary storage.

[0020] In one specific implementation scheme, the transfer assembly includes a mounting column, a linear module, a rotary cylinder, and a transfer gripper. The mounting column is disposed on one side of the second conveyor, the linear module is disposed on the side wall of the mounting column facing the second conveyor, the rotary cylinder is disposed on the movable end of the linear module, and the transfer gripper is disposed on the output end of the rotary cylinder.

[0021] By adopting the above technical solution, the linear module helps to drive the rotary cylinder and the transfer gripper to lift and lower, the transfer gripper helps to clamp the short pipe on the second conveyor, and the rotary cylinder helps to drive the transfer gripper to rotate, thereby helping to place the short pipe clamped by the transfer gripper onto the mounting frame in conjunction with the linear module.

[0022] In one specific implementation scheme, the feeding assembly includes a stepper motor, a drive gear, a driven gear, a feeding chain, and several feeding plates. The stepper motor is mounted on the outer wall of the mounting frame, the drive gear is mounted on the output shaft of the stepper motor and located inside the mounting frame, the driven gear is rotatably mounted on the inner wall of the mounting frame, the feeding chain is sleeved around the drive gear and the driven gear, and several feeding plates are spaced apart on the feeding chain.

[0023] By adopting the above technical solution, the stepper motor helps to drive the drive gear to rotate intermittently, which in turn helps to drive the feeding chain to rotate intermittently with the cooperation of the driven gear, and in turn helps to drive the short tube to move intermittently through the discharge plate.

[0024] In one specific implementation, the receiving device includes a receiving rack disposed on one side of the mounting frame. The top of the receiving rack is provided with a first feeding frame for storing unqualified short tubes. The top of the first feeding frame is detachably provided with a second feeding frame for storing qualified short tubes. The distance between the side of the second feeding frame near the mounting frame and the mounting frame is greater than the distance between the side of the first feeding frame near the mounting frame and the mounting frame. A discharge plate is rotatably disposed on the side wall of the mounting frame near the receiving rack. A top support cylinder is disposed on the mounting frame below the discharge plate, and the piston rod of the top support cylinder is hinged to the discharge plate.

[0025] By adopting the above technical solution, the top support cylinder helps to adjust the tilt angle of the feeding plate, thereby helping to adjust the position of the short tube rolling off the feeding plate, and further helping to collect and store short tubes that meet the length measurement and those that do not.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, through the arrangement of a material transfer mechanism, a buffer device, an intermittent conveying device, a transfer component, and a receiving device, utilizes a conveyor system. Conveyor 1, in conjunction with the material transfer mechanism, facilitates the temporary storage of cut short pipes within the buffer device. The intermittent conveying device sequentially and intermittently transports the short pipes stored in the buffer device to the processing positions of the chamfering device and the preliminary cleaning device for chamfering and preliminary cleaning. Conveyor 2, in conjunction with the transfer component, facilitates the transfer of the chamfered and preliminarily cleaned short pipes to the feeding component of the mounting frame. The feeding component sequentially and intermittently transports the short pipes to the processing positions of the secondary cleaning device and the length measuring device for secondary cleaning and length measurement. The receiving device separately collects and stores short pipes that meet or fail the length measurement. This facilitates the automated transfer of short pipes between different processing steps, thereby improving the transfer efficiency of short pipes between different processing steps and ultimately increasing the production efficiency of short pipes.

Detailed Implementation

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] This application discloses a short pipe processing production line, referring to... Figure 1It includes a cutting device 1, a conveyor 2 fixedly installed on the discharge side of the cutting device 1, a buffer device fixedly installed on one side of the conveyor 2, and a material transfer mechanism provided on the other side of the conveyor 2.

[0038] Reference Figure 1 and Figure 2 The material transfer mechanism includes a mounting bracket 44 installed on one side of the conveyor 2. A linear slide 45 is fixed on the top surface of the mounting bracket 44, and the length direction of the linear slide 45 is perpendicular to the length direction of the conveyor 2. A vertical rod 46 is fixedly installed at the movable end of the linear slide 45. A vertical groove 47 is opened on the side wall of the vertical rod 46 facing the conveyor 2. A lifting block 48 is slidably engaged in the vertical groove 47. A drive motor 49 is fixedly installed at the top of the vertical rod 46. A screw 50 is coaxially fixedly connected to the output end of the drive motor 49. The end of the screw 50 away from the drive motor 49 is rotatably connected to the vertical rod 46. The screw 50 passes through the lifting block 48 and is threadedly connected to the lifting block 48. A mounting plate 51 is fixedly connected to the side wall of the lifting block 48. A material transfer baffle 52 is fixedly installed on the side of the mounting plate 51 away from the lifting block 48.

[0039] Reference Figure 2 and Figure 3 The material transfer baffle 52 is provided with a material gripping assembly 53. The material gripping assembly 53 includes a mounting frame 531, a drive cylinder 532, a plug-in post 533, and a material gripping clamp 534. The mounting frame 531 is fixedly mounted on the side wall of the material transfer baffle 52. The drive cylinder 532 is fixedly mounted on the mounting frame 531, and the piston rod of the drive cylinder 532 extends horizontally. The plug-in post 533 is fixedly mounted on the piston rod of the drive cylinder 532. The end of the plug-in post 533 away from the drive cylinder 532 has an integrally formed guide part 54. The material gripping clamp 534 is fixedly mounted on the end of the plug-in post 533 near the drive cylinder 532. The material transfer baffle 52 has a clearance opening 55.

[0040] Reference Figure 1 and Figure 4 The buffer device includes a fixed frame 11 installed on one side of the conveyor 2. Buffer frame 12 and buffer frame 2 13 are fixed sequentially on the top surface of the fixed frame 11 in a direction away from the conveyor 2. The tops of buffer frame 12 and buffer frame 2 13 are both inclined. The bottom end of buffer frame 12 is arranged adjacent to the top end of buffer frame 2 13, and the bottom end of buffer frame 12 is lower than the top end of buffer frame 2 13. Material blocking blocks 14 are fixedly installed on both sides of the bottom end of buffer frame 2 13.

[0041] Reference Figure 1 and Figure 2During the production and processing of short pipes, the long pipe is cut into short pipes of a set length by the cutting device 1, and the cut short pipes are transported by the conveyor 2. At the same time, the drive motor 49 operates, and the output end of the drive motor 49 drives the screw 50 to rotate, thereby driving the lifting block 48 to slide down in the vertical groove 47. Then, through the mounting plate 51, the material transfer baffle 52 located above the conveyor 2 gradually descends until it is in close contact with the surface of the conveyor 2.

[0042] Reference Figure 2 and Figure 3 The drive cylinder 532 is turned, and the piston rod of the drive cylinder 532 extends, driving the insertion post 533 and the material gripping plate 534 to pass through the clearance opening 55. Under the guidance of the guide part 54, the insertion post 533 is gradually inserted into the inside of the short pipe, and the material gripping plate 534 cooperates with the insertion post 533 to clamp the short pipe, thereby gripping the short pipe.

[0043] Reference Figure 2 and Figure 3 After grabbing the short pipe, the drive motor 49 rotates in reverse, causing the lifting block 48 to rise within the vertical groove 47. This, in turn, moves the grabbed short pipe upwards via the mounting plate 51 and the material transfer baffle 52. Simultaneously, the linear slide 45 rotates, causing the upright 46 to move horizontally towards the conveyor 2. This, in turn, moves the material transfer baffle 52 synchronously via the lifting block 48 and the mounting plate 51 until the material transfer baffle 52 reaches the top of the buffer rack 12. Then, the drive cylinder 532 rotates in reverse, causing its piston rod to retract. This retracts the insertion post 533 and the gripping clamp 534, causing them to pass through the clearance opening 55 in the opposite direction, thus dropping the grabbed short pipe onto the buffer device.

[0044] Reference Figure 1 and Figure 2 The linear slide 45 rotates in the reverse direction, causing the upright 46 to move horizontally away from the conveyor 2. This, in turn, drives the lifting block 48 and the mounting plate 51 to move the material transfer baffle 52 synchronously until the material transfer baffle 52 moves above the conveyor 2. This cycle repeats, helping to grab the short pipes conveyed on the conveyor 2 and place them on the buffer device for temporary storage.

[0045] Reference Figure 1 and Figure 4 An intermittent conveying device is fixed on the side of the buffer device away from the conveyor 2. A chamfering device 3 and a preliminary cleaning device 4 are fixedly installed on both sides of the intermittent conveying device along the conveying direction.

[0046] Reference Figure 4 and Figure 5The intermittent conveying device includes a feeding rack 15 distributed adjacent to the buffer device. The top of the feeding rack 15 is provided with several sets of feeding slots 16 at intervals. The inside of the feeding rack 15 is fixed with a slot frame 17. Guide rails 18 are horizontally installed on the two opposite outer walls of the slot frame 17. A movable block 19 is slidably engaged on each guide rail 18. A slide rail 20 is vertically installed on the side wall of each movable block 19. A slider 21 is slidably installed on each slide rail 20. An installation block 22 is fixed on the side of each slider 21 facing away from the slide rail 20. A conveying plate 23 is fixedly installed on the top of each installation block 22. A connecting rod 42 is fixedly installed between two conveying plates 23. Several sets of clamping slots 24 are provided at intervals on the top of two conveying plates 23.

[0047] Reference Figure 5 A mounting rod 25 is fixedly connected to the bottom of the mounting block 22. A connecting column 26 is coaxially fixedly connected to the end of the mounting rod 25 away from the mounting block 22. A dual-head motor 27 is fixedly installed inside the slot frame 17. Each output end of the dual-head motor 27 passes through one side wall of the slot frame 17 and extends out of the slot frame 17. A rotating plate 28 is fixedly connected to each output end of the dual-head motor 27. An oblong hole 29 is opened through the rotating plate 28. A movable track 30 is opened on the outer wall of the slot frame 17. The connecting column 26 passes through the oblong hole 29 and is inserted into the movable track 30.

[0048] Reference Figure 5 When the dual-head motor 27 starts, the two output ends of the dual-head motor 27 drive the two rotating plates 28 to rotate, thereby driving the mounting block 22 to move through the connecting column 26 and the mounting rod 25. While the mounting block 22 moves, the sliding of the slider 21 on the slide rail 20 and the sliding of the movable block 19 in the guide rail 18 help to guide and limit the movement trajectory of the mounting block 22, thereby helping the mounting block 22 to drive the conveying plate 23 to reciprocate along the shape trajectory of the movable track 30.

[0049] Reference Figure 4 and Figure 6The fixed frame 11 is equipped with a material feeding mechanism, which includes a moving block 31 and two columns 32 fixed at intervals within the fixed frame 11. The top surface of the moving block 31 has an arc-shaped concave surface 34. Two elongated holes 33 are opened at intervals on both sides of the arc-shaped concave surface 34 on the moving block 31. Each column 32 passes through one elongated hole 33, and the side wall of each column 32 abuts against the side of the elongated hole 33 away from the feeding frame 15. A top plate 35 is installed at the top of the column 32. A vertically arranged lifting rod 36 is slidably installed on the top plate 35. A base plate 37 is fixed at the bottom end of the lifting rod 36. A roller 38 is rotatably installed on the bottom surface of the base plate 37, and the roller 38 rolls and abuts against the arc-shaped concave surface 34. A return spring 39 is sleeved around the circumferential periphery of the lifting rod 36. The bottom end of the return spring 39 is fixedly connected to the base plate 37, and the top end of the return spring 39 is fixedly connected to the top plate 35. An inclined top plate 40 is fixedly installed at the top end of the lifting rod 36. The top plate 40 is located below the bottom end of the buffer rack 12. The height of the top surface of the top plate 40 gradually decreases along the direction from the buffer rack 12 toward the buffer rack 2 13.

[0050] Reference Figure 6 The movable block 31 is provided with a connecting component 41, which includes a connecting rod 411, a connecting block 412, a transmission rod 413, and a transmission column 414. One end of the connecting rod 411 is fixedly connected to the movable block 31. The connecting block 412 is fixedly installed at the end of the connecting rod 411 away from the movable block 31. One end of the transmission rod 413 is fixedly connected to the connecting rod 42. The transmission column 414 is fixedly installed at the end of the transmission rod 413 away from the connecting rod 42. A snap-fit ​​groove 43 is provided through the connecting block 412. The transmission column 414 can be raised and lowered and snapped into the snap-fit ​​groove 43.

[0051] Reference Figure 4 , Figure 5 and Figure 6 When the two conveying plates 23 move, they drive the connecting rod 42 and the transmission rod 413 to move synchronously. This causes the connecting rod 411 and the moving block 31 to move horizontally away from the feeding rack 15 through the movable connection between the transmission column 414 and the connecting block 412. This causes the roller 38 to roll from low to high on the arc concave surface 34. During the rolling process, the lifting rod 36 and the top plate 40 are driven to rise, which helps to lift and transfer the short tube at the bottom of the buffer rack 12 to the buffer rack 2 13 through the inclined top plate 40. The short tube rolls downward on the buffer rack 2 13 and is blocked by two stop blocks 14 at the bottom of the buffer rack 2 13, thus being temporarily stored at the bottom of the buffer rack 2 13.

[0052] Reference Figure 4 and Figure 5During the reciprocating motion of the two conveyor plates 23, the two conveyor plates 23 will drive the short tube at the bottom of the buffer rack 13 to move synchronously a certain distance through the clamping groove 24 until the short tube is placed into a set of feeding grooves 16 at the top of the feeding rack 15; at the same time, the two conveyor plates 23 will transfer the short tube placed in the first set of feeding grooves 16 to the next set of feeding grooves 16 for placement.

[0053] Reference Figure 1 and Figure 4 When the short pipe is placed in a set of discharge troughs 16 between the chamfering devices 3 and between the preliminary cleaning devices 4, the chamfering devices 3 and the preliminary cleaning devices 4 will perform chamfering and preliminary cleaning on the short pipe in sequence.

[0054] Reference Figure 1 A second conveyor 5 is fixedly installed on the side of the intermittent conveying device away from the buffer device. A mounting frame 6 is fixed on the side of the second conveyor 5 away from the intermittent conveying device. A feeding assembly 7 is installed on the mounting frame 6. A secondary cleaning device 9 and a length measuring device 10 are installed sequentially on both sides of the feeding assembly 7 along the feeding direction. A receiving device is installed on the side of the mounting frame 6 away from the second conveyor 5. A transfer assembly 8 is installed on the side of the second conveyor 5 away from the mounting frame 6.

[0055] Reference Figure 7 The transfer assembly 8 includes a mounting column 81, a linear module 82, a rotary cylinder 83, and a transfer gripper 84. The mounting column 81 is fixedly installed on the side of the conveyor 5 away from the mounting frame 6. The linear module 82 is vertically fixedly installed on the side wall of the mounting column 81 facing the conveyor 5. The rotary cylinder 83 is fixedly installed on the movable end of the linear module 82. The transfer gripper 84 is fixedly installed on the output end of the rotary cylinder 83.

[0056] Reference Figure 8 The feeding assembly 7 includes a stepper motor 71, a drive gear 72, a driven gear 73, a feeding chain 74, and several feeding plates 75. In this embodiment, there are two drive gears 72, two driven gears 73, and two feeding chains 74. The stepper motor 71 is fixedly mounted on the outer side wall of the mounting frame 6. The two drive gears 72 are fixed at intervals on the output shaft of the stepper motor 71, and each drive gear 72 is close to one inner side wall of the mounting frame 6. The two driven gears 73 are rotatably mounted on the two opposite inner side walls of the mounting frame 6, and the driven gears 73 are located at the end of the mounting frame 6 away from the drive gears 72. Each feeding chain 74 is sleeved around the drive gears 72 and the driven gears 73. Several feeding plates 75 are installed at intervals on the feeding chain 74.

[0057] Reference Figure 1 , Figure 7 and Figure 8After the initial cleaning of the short pipe is completed, it is transferred to conveyor 5 for transport. When the short pipe is transported to the end of conveyor 5, it is stopped, and the linear module 82 is activated, driving the rotary cylinder 83 and the transfer gripper 84 to descend synchronously until the transfer gripper 84 reaches the gripping position. Then, the transfer gripper 84 is activated to grip the short pipe on conveyor 5; the linear module 82 rotates in the reverse direction, driving the rotary cylinder 83 and the transfer gripper 84 to rise synchronously, and at the same time, the rotary cylinder 83 is activated, driving the transfer gripper 84 and the gripped short pipe to rotate 90 degrees; then, the linear module 82 rotates in the forward direction, driving the rotary cylinder 83 and the transfer gripper 84 to descend synchronously, thereby placing the short pipe onto a set of discharge plates 75 on the feeding chain 74.

[0058] Reference Figure 8 When the short tube is placed on the feeding plate 75, the stepper motor 71 runs, driving the two drive gears 72 to rotate synchronously and intermittently. This helps the two feeding chains 74 to rotate intermittently with the cooperation of the two driven gears 73. This helps to move the short tube on the feeding plate 75 intermittently to the processing position of the secondary cleaning device 9 and the length measuring device 10. This helps to perform secondary cleaning and length measurement on the short tube in sequence through the secondary cleaning device 9 and the length measuring device 10.

[0059] Reference Figure 1 and Figure 8 The receiving device includes a receiving frame 56 fixedly installed at the end of the mounting frame 6 away from the conveyor 5. A first feeding frame 57 is fixedly installed on the top of the receiving frame 56. A second feeding frame 58 is detachably installed on the top of the first feeding frame 57. The distance between the side of the second feeding frame 58 near the mounting frame 6 and the mounting frame 6 is greater than the distance between the side of the first feeding frame 57 near the mounting frame 6 and the mounting frame 6. Two spaced-apart feeding plates 59 are rotatably installed on the side wall of the mounting frame 6 near the receiving frame 56. Two spaced-apart top support cylinders 60 are fixedly installed on the mounting frame 6 below the feeding plates 59. The piston rod of each top support cylinder 60 is hinged to the feeding plate 59, and the top support cylinder 60 is electrically connected to the length measuring device 10.

[0060] Reference Figure 8When the length measuring device 10 detects that the length of the short tube is qualified, the short tube rolls onto the discharge plate 59 under the combined action of the feeding chain 74 and the discharge plate 75. At this time, the bottom end of the discharge plate 59 is above the second discharge frame 58, so that the short tube rolls along the discharge plate 59 into the second discharge frame 58 for storage. When the length measuring device 10 detects that the length of the short tube is unqualified, the short tube rolls onto the discharge plate 59 under the combined action of the feeding chain 74 and the discharge plate 75. At the same time, the length measuring device 10 transmits a signal to the top support cylinder 60, the piston rod of the top support cylinder 60 retracts, driving the discharge plate 59 to rotate, so that the bottom end of the discharge plate 59 rotates to above the first discharge frame 57, so that the short tube rolls along the discharge plate 59 into the first discharge frame 57 for storage.

[0061] The implementation principle of this embodiment is as follows: During the production and processing of short pipes, the long pipe is cut into short pipes of a set length by the cutting device 1, and the cut short pipes are transported by the conveyor 2. At the same time, the drive motor 49 operates, and the output end of the drive motor 49 drives the screw 50 to rotate, thereby driving the lifting block 48 to slide down in the vertical groove 47. Then, the mounting plate 51 drives the material transfer baffle 52 located above the conveyor 2 to gradually descend until it is in close contact with the surface of the conveyor 2. After that, the drive cylinder 532 operates, and the piston rod of the drive cylinder 532 extends, driving the insertion post 533 and the gripping clamp 534 to pass through the clearance opening 55. Under the guidance of the guide part 54, the insertion post 533 is gradually inserted into the interior of the short pipe, and the gripping clamp 534 cooperates with the insertion post 533 to clamp the short pipe, thereby grasping the short pipe.

[0062] After the short pipe is grasped, the drive motor 49 rotates in reverse, causing the lifting block 48 to rise within the vertical groove 47. This, in turn, moves the grasped short pipe upward via the mounting plate 51 and the material transfer baffle 52. Simultaneously, the linear slide 45 rotates, causing the upright 46 to move horizontally towards the conveyor 2. This, in turn, moves the material transfer baffle 52 synchronously via the lifting block 48 and the mounting plate 51 until the material transfer baffle 52 reaches the top of the buffer rack 12. Then, the drive cylinder 532 rotates in reverse, its piston rod retracting. This causes the insertion post 533 and the gripping clamp 534 to pass through the clearance opening 55 in the opposite direction, causing the grasped short pipe to fall to the top of the buffer rack 12 and roll to the bottom for temporary storage.

[0063] The linear slide 45 rotates in reverse, causing the upright 46 to move horizontally away from the conveyor 2. This, in turn, drives the material transfer baffle 52 to move synchronously via the lifting block 48 and the mounting plate 51, until the material transfer baffle 52 moves above the conveyor 2. This cycle repeats, helping to grab the short pipes conveyed on the conveyor 2 and place them on the buffer rack 12 for temporary storage.

[0064] When the dual-head motor 27 is started, the two output ends of the dual-head motor 27 drive the two rotating plates 28 to rotate, thereby driving the mounting block 22 to move through the connecting column 26 and the mounting rod 25. While the mounting block 22 is moving, the sliding of the slider 21 on the slide rail 20 and the sliding of the movable block 19 in the guide rail 18 help to guide and limit the movement trajectory of the mounting block 22, thereby helping the mounting block 22 to drive the conveying plate 23 to reciprocate along the shape trajectory of the movable track 30.

[0065] When the two conveying plates 23 move, they drive the connecting rod 42 and the transmission rod 413 to move synchronously. This causes the connecting rod 411 and the moving block 31 to move horizontally away from the feeding rack 15 through the movable connection between the transmission column 414 and the connecting block 412. This causes the roller 38 to roll from low to high on the arc concave surface 34. During the rolling process, the lifting rod 36 and the top plate 40 are driven to rise, which helps to lift and transfer the short tube at the bottom of the buffer rack 12 to the buffer rack 2 13 through the inclined top plate 40. The short tube rolls downward on the buffer rack 2 13 and is blocked by two stop blocks 14 at the bottom of the buffer rack 2 13, thus being temporarily stored at the bottom of the buffer rack 2 13.

[0066] During the reciprocating motion of the two conveyor plates 23, the two conveyor plates 23 will drive the short tubes at the bottom of the buffer rack 13 to move synchronously a certain distance through the clamping groove 24 until the short tubes are placed into a set of feeding grooves 16 at the top of the feeding rack 15; at the same time, the two conveyor plates 23 will transfer the short tubes placed in one set of feeding grooves 16 to the next set of feeding grooves 16. When the short tubes are placed into a set of feeding grooves 16 between the chamfering devices 3 and a set of feeding grooves 16 between the preliminary cleaning devices 4, the chamfering devices 3 and the preliminary cleaning devices 4 will perform chamfering and preliminary cleaning on the short tubes in sequence.

[0067] After the short pipe is initially cleaned, the moving conveyor plate 23 transfers the short pipe to the conveyor 5 for transport. When the short pipe is transported to the end of the conveyor 5, it is stopped, and the linear module 82 starts, driving the rotary cylinder 83 and the transfer gripper 84 to descend synchronously until the transfer gripper 84 reaches the gripping position. Then, the transfer gripper 84 starts to grip the short pipe on the conveyor 5; the linear module 82 rotates in the reverse direction, driving the rotary cylinder 83 and the transfer gripper 84 to rise synchronously, and at the same time, the rotary cylinder 83 starts, driving the transfer gripper 84 and the gripped short pipe to rotate 90 degrees; then, the linear module 82 rotates in the forward direction, driving the rotary cylinder 83 and the transfer gripper 84 to descend synchronously, thereby placing the short pipe onto a set of discharge plates 75 on the feeding chain 74.

[0068] After the short tube is placed on the feeding plate 75, the stepper motor 71 starts, driving the two drive gears 72 to rotate synchronously and intermittently. This helps the two feed chains 74 to rotate intermittently with the cooperation of the two driven gears 73. This helps to move the short tube on the feeding plate 75 intermittently to the processing position of the secondary cleaning device 9 and the length measuring device 10. This helps to perform secondary cleaning and length measurement on the short tube in sequence through the secondary cleaning device 9 and the length measuring device 10.

[0069] When the length measuring device 10 detects that the length of the short tube is qualified, the short tube rolls onto the discharge plate 59 under the combined action of the feeding chain 74 and the discharge plate 75. At this time, the bottom end of the discharge plate 59 is above the second discharge frame 58, so that the short tube rolls along the discharge plate 59 into the second discharge frame 58 for storage. When the length measuring device 10 detects that the length of the short tube is unqualified, the short tube rolls onto the discharge plate 59 under the combined action of the feeding chain 74 and the discharge plate 75. At the same time, the length measuring device 10 transmits a signal to the top support cylinder 60, the piston rod of the top support cylinder 60 retracts, driving the discharge plate 59 to rotate, so that the bottom end of the discharge plate 59 rotates to above the first discharge frame 57, so that the short tube rolls along the discharge plate 59 into the first discharge frame 57 for storage.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
