Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and in particular to a perforation machine for drip tubes. Background Technology

[0002] Drip irrigation is a water-saving irrigation method, typically achieved by laying drip irrigation pipes in the planting area. Drip irrigation pipes are classified according to the form of their internal drippers, including sheet drippers, columnar drippers, and strip drippers. Strip drippers, in particular, are widely used because they can be continuously laid along the length of the drip irrigation pipe after processing, reducing the manufacturing difficulty and improving the efficiency of drip irrigation pipe production. For example, patent publication number EP1929859A1 discloses a metering element for drip irrigation pipes, a method and apparatus for producing the metering element, in which strip drippers are embedded in the inner wall of a water pipe, and then holes are drilled at corresponding positions in the inner wall of the water pipe to form the strip dripper. Because the drippers on the inner wall of the water pipe are strip-shaped and relatively thin, during the actual drilling process, the drilling tool can easily puncture both the pipe wall and the dripper, leading to a decrease in the quality of the drip strip and affecting the overall performance of the drip irrigation system. Therefore, how to design a technology to improve the drilling quality to enhance the overall quality and performance of the drip strip is the technical problem this application aims to solve.

[0018] like Figures 1-5 As shown, this application provides a perforation machine for drip tubes, comprising: Rack 1; The scribing assembly 2 includes a scribing frame 21, a scribing knife 22, a rotating seat 23, and a rotating drive 24. The rotating seat 23 is rotatably mounted on the scribing frame 21, the scribing knife 22 is mounted on the rotating seat 23, and the rotating drive 24 is used to drive the rotating seat 23 to rotate. The scribing frame 21 is mounted on the frame 1. The guide assembly 3 includes a traction roller 31, a support roller 32, and a traction drive component 33. The support roller 32 and the traction roller 31 are arranged vertically in a staggered manner and are rotatably mounted on the frame 1. The traction drive component 33 is configured to drive the traction roller 31 to rotate. The axis of the rotating seat 23 is parallel to the axis of the traction roller 31, and the rotating seat 23 is located on one side of the support roller 32. When the scribing knife 22 is in the scribing position, the cutting edge of the scribing knife 22 is positioned towards the roller surface of the support roller 32, and a gap is formed between the cutting edge of the scribing knife 22 and the roller surface of the support roller 32.

[0019] Specifically, the drip tube scribing machine provided in this embodiment is equipped with a scribing assembly 2 and a guide assembly 3 on a frame 1. The support roller 32 in the guide assembly 3 is used to support the drip tube to cooperate with the scribing knife 22 for scribing, and the traction roller 31 is used to traction and transport the drip tube. The scribing knife 22 is driven by a rotating seat 23 to scribing the drip tube on the support roller 32.

[0020] Because the traction roller 31 and support roller 32 in the guide assembly 3 are staggered vertically, the traction roller 31 pulls the dripping tube at the bottom of the support roller 32. This allows the dripping tube to bend and press against the surface of the support roller 32, ensuring that the dripping tube is tightly attached to the support roller 32. This maintains a relatively consistent distance between the outer wall of the upper layer of the dripping tube and the support roller 32 during the traction state. When the dripping tube is perforated by the scouring knife 22, the distance between the scouring knife 22 and the support roller 32 remains at a set value, allowing for precise and reliable perforation of the tube wall without damaging the strip-shaped dripper inside the tube.

[0021] By staggering the traction roller 31 and support roller 32 in the guide assembly 3, the drip tube can be wound in an arc around the top of the support roller 32 to effectively support the drip tube that needs to be perforated during the perforation process. Since the drip tube is tightly bound to the support roller 32, the distance between the tube wall and the support roller 32 is kept essentially unlimited. The traction roller 31 provides traction force to the drip tube to drive its transport. The perforation knife 22 in the perforation assembly 2 can rotate with the rotating seat 23. The blade of the perforation knife 22 forms a set distance interval with the roller surface of the support roller 32. In this way, the blade can accurately cut the drip tube on the support roller 32, ensuring that the perforation knife 22 can effectively cut the tube wall of the drip tube without damaging the strip dropper in the drip tube, thereby improving the perforation quality and improving the overall quality and performance of the drip tube.

[0022] Furthermore, the scribing assembly 2 also includes a first slide rail 25 and a sliding drive member 26. The scribing frame 21 is slidably disposed on the first slide rail 25, and the sliding drive member 26 is configured to drive the scribing frame 21 to slide along the first slide rail 25. The first slide rail 25 is disposed on the frame 1 and extends toward the support roller 32.

[0023] Specifically, to facilitate operation, the scribing frame 21 is slidably mounted on the frame 1. The scribing frame 21 can slide on the first slide rail 25. The scribing frame 21 is driven to move by the sliding drive component 26, so that the scribing frame 21 can drive the rotating seat 23 to move closer to or away from the support roller 32.

[0024] In actual use, the produced drip strips are manually wound onto the support roller 32 and the traction roller 31. At this time, the scribing frame 21 drives the rotating seat 23 away from the support roller 32. After the drip strips are wound onto the support roller 32, the sliding drive component 26 drives the scribing frame 21 to move the rotating seat 23 closer to the support roller 32.

[0025] To meet the requirements of driving the rotary seat 23, the rotary drive 24 is also mounted on the scouring frame 21. The rotary drive 24 can be a stepper motor or a servo motor, the sliding drive 26 can be a cylinder or a linear motor, and the traction drive 33 can be a motor. Here, there are no restrictions on the physical manifestations of the rotary drive 24 and the sliding drive 26.

[0026] Furthermore, the scribing assembly 2 also includes a second slide rail 27, a pad 28, and an adjustment drive 29. The surface of the pad 28 facing the scribing frame 21 is an inclined surface 281. The pad 28 is slidably disposed on the second slide rail 27. The adjustment drive 29 is configured to drive the pad 28 to slide along the second slide rail 27. The second slide rail 27 is disposed on the frame 1 and extends toward the support roller 32, and the extension directions of the first slide rail 25 and the second slide rail 27 are arranged intersectingly.

[0027] Specifically, the second slide rail 27 configured in the scribing assembly 2 meets the sliding installation requirements of the pad 28. The adjusting drive 29 drives the pad 28 to slide back and forth along the second slide rail 27, thereby limiting the movement position of the scribing frame 21 through the pad 28, ensuring that the scribing frame 21 drives the rotating seat 23 to move to the precise position.

[0028] In actual use, in order to ensure that the cutting depth of the scribing knife 22 is accurate, it is necessary to precisely control the position of the scribing frame 21. The scribing frame 21 is limited by the inclined surface 281 of the pad 28. During the debugging stage, the position of the scribing frame 21 is adjusted by adjusting the position of the pad 28, thereby controlling the cutting depth of the scribing knife 22.

[0029] By using the inclined surface 281 on the upper surface of the pad 28 to limit the engagement with the scouring frame 21, the inclined surface 281 can make more precise fine adjustments to the position, so as to accurately control the scouring depth of the scouring knife 22.

[0030] Furthermore, the adjustment drive 29 is a linear motor, which is configured to drive the pad 28 to slide along the second slide rail 27. Specifically, the linear motor can automatically push the pad 28 to reciprocate, thereby adjusting the position of the pad 28 relative to the scribing frame 21.

[0031] Alternatively, the adjusting drive component 29 may be a first screw, and the pad 28 may have a first threaded hole. The first screw may be rotatably mounted on the frame 1 and threadedly engaged with the first threaded hole. Specifically, the first screw is threadedly connected to the pad 28, and the operator adjusts the position of the pad 28 by rotating the first screw.

[0032] Furthermore, the guiding assembly 3 also includes a guide belt 34 and a plurality of mounting rollers 35, the plurality of mounting rollers 35 being rotatably mounted on the frame 1, and the guide belt 34 being wound around the plurality of mounting rollers 35; The guide belt 34 presses against the traction roller 31.

[0033] Specifically, in order to improve the reliability and smoothness of the traction roller 31 in conveying the dripping tube, and to ensure that the scribing knife 22 can continuously and accurately scribing at the designated position during continuous production, the dripping tube is pressed onto the traction roller 31 by the guide belt 34 during the traction roller 31 in conveying the dripping tube, so as to ensure that the dripping tube can be smoothly conveyed by the traction roller 31.

[0034] The traction drive unit 33 can synchronously drive the traction roller 31 and the mounting roller 35 to rotate synchronously, or the mounting roller 35 can be configured with an independent motor drive so that the guide belt 34 can match the traction roller 31 to synchronously convey the drip strip.

[0035] Furthermore, a traction channel is formed between the guide belt 34 and the roller surface of the traction roller 31 for the drip strip to pass through, and the traction channel has an arc-shaped structure.

[0036] Specifically, the portion of the guide belt 34 that abuts against the surface of the traction roller 31 is arc-shaped, so as to press the drip strip against the surface of the traction roller 31 using the guide belt 34. The drip strip has a sufficiently large contact area with the traction roller 31 and the guide belt 34 to ensure smooth delivery of the drip strip.

[0037] Furthermore, the guide assembly 3 also includes a pressure roller 36, a mounting base 37, and a pressure drive 38. The pressure roller 36 is rotatably mounted on the mounting base 37, and the pressure drive 38 is configured to drive the mounting base 37 to press the pressure roller 36 onto the guide belt 34.

[0038] Specifically, tension is applied to the guide belt 34 by the pressure roller 36, so that the guide belt 34 can press the drip tube firmly onto the traction roller 31. The pressure drive 38 can be a cylinder to ensure that the pressure roller 36 can press firmly onto the guide belt 34.

[0039] Furthermore, a first anti-tangling pressure plate 211 is provided on the scribing frame 21. The first anti-tangling pressure plate 211 is an arc-shaped plate and is arranged on one side of the support roller 32. The first anti-tangling pressure plate 211 is configured to press the drip tube onto the support roller 32. Along the conveying direction of the drip tube, the first anti-tangling pressure plate 211 and the rotating seat 23 are arranged in sequence.

[0040] Specifically, the first anti-tangling pressure plate 211 set on the scribing frame 21 can press the drip strip onto the support roller 32. Since the first anti-tangling pressure plate 211 is an arc-shaped plate, it can prevent the drip strip from tangling during high-speed conveying, thereby improving the reliability of use.

[0041] In one embodiment, a second anti-tangle pressure plate 11 is provided on the frame 1. The second anti-tangle pressure plate 11 is an arc-shaped plate and is arranged on one side of the traction roller 31. The second anti-tangle pressure plate 11 is configured to press the drip tube onto the traction roller 31. The second anti-tangle pressure plate 11 and the traction roller 31 are arranged sequentially along the conveying direction of the drip tube.

[0042] Specifically, the second anti-tangling pressure plate 11 installed on the frame 1 presses the drip strip onto the traction roller 31 during use. Similarly, the second anti-tangling pressure plate 11 is an arc-shaped plate, which can prevent the drip strip from tangling during high-speed conveying, thereby improving the reliability of use.

[0043] Furthermore, the drip tube dicing machine also includes a guide assembly 4, which includes a guide frame 41, a second screw 42 and a guide rod 43. The guide frame 41 is provided with a guide groove 411 for the drip tube to pass through, and the second screw 42 is rotatably mounted on the guide frame 41. The frame 1 is also provided with a second threaded hole (unmarked), and the second screw 42 is threadedly engaged with the second threaded hole; The guide rod 43 is fixedly mounted on the frame 1 and arranged parallel to the rotation axis of the support roller 32. The second screw 42 is arranged parallel to the guide rod 43 and is configured to drive the guide frame 41 to slide along the guide rod 43. The guide frame 41 is arranged below the side of the support roller 32, and the guide groove 411 is configured to guide the drip strip to be conveyed onto the support roller 32.

[0044] Specifically, in order to improve the accuracy of dicing and ensure that the drip strip wound on the support roller 32 is located directly below the dicing knife 22, a guide frame 41 is provided diagonally below the support roller 32. The guide groove 411 formed in the guide frame 41 guides the drip strip to be transported to the support roller 32 and abuts against the surface of the support roller 32. The drip strip is restricted by the position of the guide groove 411 to ensure that the drip strip can be arranged directly below the dicing knife 22, thereby improving the accuracy of dicing and improving the quality of the opening.

[0045] When adjusting the position of the guide frame 41, the second screw 42 is rotated. The second screw 42 will drive the guide frame 41 to move closer to or further away from the frame 1 to adjust the position of the guide groove 411.

[0046] Furthermore, the guide frame 41 includes a sleeve 412, two guide plates 413, and two adjusting nuts 414. The outer wall of the sleeve 412 forms left and right external threads. The sleeve 412 is sleeved on the second screw 42. The adjusting nuts 414 are connected to the guide plates 413 by screws. The adjusting nuts 414 are threaded onto the left and right external threads of the sleeve 412. The two guide plates 413 are arranged opposite to each other, and the guide groove 411 is formed between the two guide plates 413. The guide rod 43 passes through the guide plate 413.

[0047] Specifically, to facilitate the adjustment of the position of the guide frame 41 relative to the support roller 32 and to improve the versatility of the guide frame 41 to meet the scribing requirements of drip strips of different sizes and specifications, the guide frame 41 mounts two guide plates 413 onto the sleeve 412 via adjusting nuts 414. When it is necessary to adjust the distance between the two guide plates 413, rotating the sleeve 412 causes the two adjusting nuts 414 to move back and forth, thereby adjusting the distance between the two guide plates 413 to meet the usage requirements of drip strips of different sizes and specifications.

[0048] The sleeve 412 is fitted onto the smooth section of the second screw 42. Baffles are provided at both ends of the sleeve to restrict the axial movement of the sleeve 412 on the second screw 42. The guide frame 41 can be moved by rotating the second screw 42.

[0049] In one embodiment, the drip tube perforation machine further includes a detection component 5; The detection component 5 includes a mounting bracket 51, a camera 52, and an adjustment frame 53. The adjustment frame 53 is provided with a plurality of rotatable rollers 54, which are arranged sequentially along an arc. The camera 52 is mounted on the mounting bracket 51. The mounting bracket 51 is disposed on the frame 1, and the adjusting bracket 53 is disposed on the frame 1 and located between the traction roller 31 and the support roller 32; The camera 52 is configured to capture images of the dropper tube between the roller 54 and the support roller 32.

[0050] Specifically, to monitor the quality of the scribing in the drip tube in real time, a detection component 5 is installed on the frame 1. The camera 52 in the detection component 5 captures images of the drip tube during transport. Image recognition technology is used to determine if the scribing position meets the requirements, and the scribing tool 22 is automatically adjusted based on the image quality. The images captured by the camera 52 are transmitted to a computer for image recognition processing. Specific procedures for image recognition processing can be found in existing software programs and are not described in detail here.

[0051] By setting multiple arc-shaped rollers 54 on the adjustment frame 53, the drip tube between the rollers 54 and the support roller 32 can be kept straight to meet the image quality requirements of the camera 52.

[0052] In order to automatically adjust the scouring knife according to the image information collected by the camera, the scouring frame is also provided with a linear bearing 212, a threaded hole 213 and a through hole 214. The linear bearing 212 is provided with a guide rod 215 and a support seat 216 is provided on the guide rod 215. The support base 216 is provided with a servo motor 217 and the rotary drive component. The support base 216 is also provided with a rotatable lead screw 218 and a drive shaft 219. The servo motor 217 is driven to the lead screw 218, and the rotary drive component is driven to the drive shaft 219. The rotary base is fixedly mounted on the drive shaft 219. The lead screw 218 is threaded into the threaded hole 213, and the drive shaft 219 passes through the through hole 214. The detection component 5 includes a controller configured to control the operation of the servo motor 217 based on image information acquired by the camera.

[0053] Specifically, the opening position on the dropper tube is preferably located in the middle of the width direction of the dropper tube. This ensures that the dropper tube can be precisely scored, which improves the quality of the scoring and avoids scratching or damaging the dropper strip inside the tube. The controller can be a conventional industrial computer or general-purpose computer; there are no restrictions on its use.

[0054] Therefore, during the image acquisition process of the scribed dropper tube using a camera, if image recognition technology determines that the scribed position on the dropper tube is skewed and exceeds the set range, the controller will activate the servo motor 217. The servo motor 217 drives the lead screw 218 to rotate. The lead screw engages with the threaded hole 213 of the scriber. Since the scriber does not move laterally, the rotating lead screw 218 will cause the support base 216 to move laterally relative to the scriber via the guide rod 215 and the linear bearing 212. The servo motor 217 can precisely control the number of rotations of the lead screw 218 to achieve precise control over the movement distance of the support base 216. The rotating seat is mounted on the drive shaft 219 on the support base 216. The movement of the support base 216 will cause the rotating seat to move synchronously, thus adjusting the scribed position of the scriber.

[0055] The controller automatically adjusts the scribing position of the scribing knife based on the image information captured by the camera, thereby enabling timely adjustment of the scribing knife position during continuous production. This precise control of the scribing position improves the scribing quality of the drip strips and ultimately enhances product quality.

[0056] Furthermore, in order to ensure that the rotating seat where the scouring tool is located can obtain stable and reliable support while satisfying the position adjustment of the scouring tool, the drive shaft 219 needs to be reliably supported. For this purpose, an installation sleeve 210 is sleeved on the outside of the drive shaft 219, and a bearing (unmarked) is provided in the installation sleeve 210, through which the drive shaft 219 passes.

[0057] In order to meet the installation requirements of the mounting sleeve 210, two linear bearings 212 are provided on the scribing frame. Correspondingly, two guide rods 215 are configured to cooperate with the linear bearings 212. A fixed bracket (unmarked) is provided at the end of the guide rod 215 away from the support seat 216. One end of the mounting sleeve 210 is fixedly installed on the support seat 216, and the other end of the mounting sleeve 210 is fixedly installed on the fixed bracket.

[0058] Specifically, by setting an installation sleeve that can move together with the support 216 and the guide rod 215, the bearing in the installation sleeve can support the drive shaft 219, thereby ensuring that the drive shaft 219 can stably and reliably support the installation rotating seat to improve the scouring accuracy of the scouring tool during scouring.

[0059] The technical solution of this invention has the following technical advantages over the prior art: By arranging the traction roller and support roller in the guide assembly in a staggered manner, the dripping tube can be wound in an arc around the top of the support roller to effectively support the dripping tube that needs to be perforated during the perforation process. Since the dripping tube is tightly bound to the support roller, the distance between the tube wall and the support roller is kept essentially unlimited. The traction roller will provide traction force to the dripping tube to drive its transport. The perforating knife in the perforation assembly can rotate together with the rotating seat. The blade of the perforating knife and the roller surface of the support roller form a set distance interval. In this way, the dripping tube on the support roller can be precisely cut by the blade, ensuring that the perforating knife can effectively cut the tube wall of the dripping tube without damaging the strip-shaped drip tip in the dripping tube, thereby improving the perforation quality and improving the overall quality and performance of the dripping tube.
