Description

Technical Field

[0001] This utility model relates to an improvement of the cylinder body for an inlaid patch type dripper screening machine, belonging to the technical field of inlaid patch type drip irrigation pipe production equipment, specifically a cylinder body with two outer track grooves for an inlaid patch type dripper screening machine. Background Technology

[0002] Embedded drip irrigation tubing is currently the most commonly used water-saving irrigation equipment. This type of tubing consists of flat, elongated, strip-shaped drippers evenly adhered to the inner wall of the tubing. A punching device precisely drills water outlets into the drip tape, aligning with the outlet grooves of the drippers. With an internal water pressure of 0.1 MPa, it provides uniform dripping and excellent water-saving performance. The dripper itself is a long, strip-shaped body with a groove on one side at the bottom. The top surface of the dripper body features a labyrinthine flow channel and an outlet groove, while the bottom surface has an inlet connected to the outlet groove via the labyrinthine flow channel. This type of embedded drip irrigation tubing is manufactured using equipment including a feeding machine, screening machine, conveyor rail, delivery machine, main unit, sizing device, cooling device, traction punching machine, wire laying machine, winding machine, and control cabinet.

[0003] For example, Shandong Hengxiang Plastic Machinery Co., Ltd. filed a Chinese patent application on October 9, 2023, entitled "Inlaid Patch Type Drip Head Dual-Rail Screening Machine and Special Cylinder," patent number CN202322697786.4. This inlaid patch type drip head dual-track screening machine includes a frame, power control box, air source control box, cylinder, chassis, rotating track ring, pressure ring, main motor, main reducer, auxiliary motor, auxiliary reducer, inclined base, air pipe, and compressed air source. The special cylinder of this inlaid patch type drip head dual-track screening machine is composed of an upper ring and a lower ring, both of which are cylindrical. The inner diameters of the upper and lower rings are the same, but the outer diameter of the lower ring is larger than that of the upper ring. The upper ring has a circumference with... The device has an upper ring opening; the upper panel of the lower ring has an annular outer track groove along its edge; the lower ring between the outer wall of the upper ring and the outer track groove has a flat blow pipe mounting hole; the inner wall of the lower ring has a flat blow hole that matches the flat blow pipe mounting hole; the peripheral sidewall of the lower ring has an upper blow pipe mounting hole; the bottom of the outer track groove has an upper blow oblique hole that communicates with the upper blow pipe mounting hole; the upper plate of the lower ring at the bottom of the upper ring opening has a guide groove that communicates with the beginning of the outer track groove; the outer side of the upper panel of the lower ring at the upper ring opening has a conveyor track mounting groove, and the end of the outer track groove communicates with the track groove of the conveyor track fixed on the conveyor track mounting groove.

[0004] The current dedicated cylinder of this type of embedded patch-type dripper dual-track screening machine has the following shortcomings: since only the screening track groove on the rotating track ring plays a screening role, although it can ensure that most patch-type drippers are placed correctly, a very small number of incorrectly placed patch-type drippers will enter the guide groove and eventually stick to the inner wall of the tube, thus producing defective products; since there is only one annular outer track groove on the upper plate of the lower ring body, the number of patch-type drippers stored is relatively small, which cannot meet the needs of production lines with a production speed of more than 400 per minute. Summary of the Invention

[0005] The purpose of this utility model is to provide a cylindrical body with two external track grooves for use in an inlaid dripper screening machine. This machine has two connected outer track grooves on the upper plate of the lower ring body to hold drippers, thus meeting the material supply needs of production lines with a production speed of 400 drippers per minute or more, shortening the length of the conveyor track.

[0033] This embedded patch-type dripper screening machine uses a cylindrical body with two outer track grooves, including an upper ring body 1, a lower ring body 2, a guide plate 5, an infrared probe 14 (number one), and an infrared probe 16 (number two). The upper ring body 1 is fixedly installed on the upper part of the lower ring body 2. Both the upper ring body 1 and the lower ring body 2 are cylindrical, with their central axes coinciding. The inner diameters of the upper ring body 1 and the lower ring body 2 are the same, while the outer diameter of the lower ring body 2 is larger than that of the upper ring body 1. In actual production, the upper ring body 1 and the lower ring body 2 are machined from a single cylindrical body. An upper ring body opening 13 is provided on the circumferential wall of the upper ring body 1. 3. A guide groove 10 is provided on the upper plate of the lower ring body 2 at the bottom, and a guide plate 5 is provided inside the guide groove 10; a conveying track mounting groove 12 is provided on the outer side of the upper plate of the lower ring body 2 located at the opening 13 of the upper ring body; the first infrared probe 14 is fixed on the upper ring body 1 by the first bracket 15, and the second infrared probe 16 is fixed on the upper ring body 1 by the second bracket 17. The first infrared probe 14 and the second infrared probe 16 are respectively connected to the PLC control box of the embedded patch type dripper screening machine by wires; the PLC control box of the embedded patch type dripper screening machine is electrically connected to the gas source control box, and the working status of the gas source conveying in the gas source control box is controlled by the PLC control box.

[0034] The lower ring body 2 has horizontal blowing pipe mounting holes 3 spaced apart around its circumference. The inner wall of the lower ring body 2 has horizontal blowing holes 32 that match the horizontal blowing pipe mounting holes 3. A horizontal blowing pipe 31, located within the horizontal blowing pipe mounting holes 3, communicates with the matching horizontal blowing holes 32. The horizontal blowing pipe 31 is connected to the air source control box of the embedded patch-type dripper screening machine via a corresponding air pipe. Its characteristic is that:

[0035] The lower ring body 2 has an inner outer track groove 6 and an outer outer track groove 7 on its upper plate. The outlet end of the guide groove 10 is connected to the inlet end of the inner outer track groove 6, the outlet end of the inner outer track groove 6 is connected to the inlet end of the outer outer track groove 7, and the outlet end of the outer outer track groove 7 is connected to the track groove of the conveying track fixed on the conveying track mounting groove 12. The flat blow pipe mounting hole 3 is located between the outer wall of the upper ring body 1 and the inner outer track groove 6.

[0036] The inner ring outer track groove 6 has an inner ring upward blowing oblique hole 61 spaced apart at the bottom of its cavity, and the inner ring upward blowing oblique hole 61 is connected to a matching inner ring air pipe connector 62; the outer ring outer track groove 7 has an outer ring upward blowing oblique hole 71 spaced apart at the bottom of its cavity, and the outer ring upward blowing oblique hole 71 is connected to a matching outer ring air pipe connector 72; the inner ring air pipe connector 62 and the outer ring air pipe connector 72 are respectively connected to the air source control box of the embedded patch type drip head screening machine through corresponding air pipes.

[0037] The top of the inner ring outer track groove 6 and the outer ring outer track groove 7 is covered with a transparent cover plate 11, and the transparent cover plate 11 and the lower ring body 2 are clamped and fixed together by the clamping device 4. Since the transparent cover plate 11 is covered on the top of the inner ring outer track groove 6 and the outer ring outer track groove 7, the patch-type drip head can only be conveyed one after another, and the patch-type drip head is prevented from detaching from the inner ring outer track groove 6 and the outer ring outer track groove 7. The staff can also see the conveying status of the patch-type drip head in the inner ring outer track groove 6 and the outer ring outer track groove 7 through the transparent cover plate 11.

[0038] A pressing device 8 and a misaligned drip removal device 9 are provided on the upper plate of the upper ring body 2 located at the inlet end of the inner ring outer track groove 6. The pressing device 8 is located between the misaligned drip removal device 9 and the guide groove 10. The first infrared probe 14 is located above the inner ring outer track groove 6 behind the misaligned drip removal device 9 to detect whether there are patch-type drips in the inner ring outer track groove 6 behind the misaligned drip removal device 9, and transmits the detection signal to the PLC control box of the embedded patch-type drip sorting machine. The second infrared probe 16 is located above the inner ring outer track groove 6 in front of the pressing device 8 to detect whether there are patch-type drips in the inner ring outer track groove 6 in front of the pressing device 8, and transmits the detection signal to the PLC control box of the embedded patch-type drip sorting machine.

[0039] The aforementioned misaligned drip head removal device 9 includes an upward blowing connector 93, a sliding cover 94, a removal fixing seat 95, a removal cylinder 96, and a stop block 97. A sliding cover mounting groove 91 is provided on the upper plate of the upper ring body 2 located at the inlet end of the inner ring outer track groove 6. A removal cylinder 96 is fixedly mounted on the side wall of the upper ring body 2 outside the sliding cover mounting groove 91 via the removal fixing seat 95. A horizontally sliding sliding cover 94 is fixedly mounted at the front end of the piston rod of the removal cylinder 96. The sliding cover 94 is disposed within the sliding cover mounting groove 91. A stop block 97 and an upward blowing through hole 92 are provided at the bottom of the cavity of the inner ring outer track groove 6 below the sliding cover mounting groove 91. An upward blowing connector 93 is fixedly mounted at the lower end of the upward blowing through hole 92. The position of the stop block 97 is adapted to the sliding groove at the bottom side of the patch-type drip head. This ensures that only correctly positioned patch-type drippers can pass through the position of the stop 97, while incorrectly positioned patch-type drippers are blocked by the stop 97 and cannot move forward. The top-blowing connector 93 and the removal cylinder 96 are respectively connected to the air source control box of the embedded patch-type dripper screening machine through air pipes. If the second infrared probe 16 can detect the patch-type dripper but the first infrared probe 14 cannot detect the patch-type dripper, it indicates that an incorrectly positioned patch-type dripper is blocked by the stop 97. The stop 97 is located at the rear end of the sliding cover mounting groove 91, and the length from the stop 97 to the front end of the sliding cover mounting groove 91 is adapted to the length of one patch-type dripper. The top-blowing through hole 97 is located in the middle of the sliding cover mounting groove 91.

[0040] The aforementioned top-pressing device 8 consists of a top-pressing fixing seat 82, a top-pressing cylinder 83, and a ejector pin 84. A top-pressing device mounting groove 81 is provided on the upper plate of the upper ring body 2 located at the inlet end of the inner ring outer track groove 6. The top-pressing device mounting groove 81 is located in front of the sliding cover mounting groove 91. The top-pressing cylinder 83 is fixedly installed in the top-pressing device mounting groove 81 through the top-pressing fixing seat 82. The ejector pin 84 at the front end of the piston rod of the top-pressing cylinder 83 passes through the top-pressing fixing seat 82 and extends into the cavity of the inner ring outer track groove 6 below the top-pressing fixing seat 82. The top-pressing cylinder 83 is connected to the air source control box of the embedded patch type dripper screening machine through a corresponding air pipe.

[0041] The clamping device 4 consists of a slot 41, a screw 42, a handle 43, and a pressure plate 44. The top plate of the slot 41 is placed on the upper plate of the transparent cover plate 11, and the bottom plate of the slot 41 is placed below the bottom plate of the lower ring body 2. The screw 42 is threadedly connected to the screw hole on the bottom plate of the slot 41. The upper end of the screw 42 is fixed with the pressure plate 44, and the lower end of the screw 42 is fixed with the handle 43. Rotating the handle 43 adjusts the position of the pressure plate 44. The top plate of the slot 41 and the pressure plate 44 clamp the transparent cover plate 11 and the lower ring body 2 on both sides, thereby fixing the transparent cover plate 11 to the top of the upper ring body 2 and completely covering the inner ring outer track groove 6 and the outer ring outer track groove 7.

[0042] A rubber pad 45 is fixedly provided on the upper plate of the pressure plate 44 to provide a certain cushioning effect.

[0043] The guide plate 5 is fixedly installed on the inner wall of the upper ring 1 at the opening 13 of the upper ring body. The front part of the guide plate 5 is provided with a downward blowing oblique hole 51, and a downward blowing pipe is fixedly installed on the downward blowing oblique hole 51. The downward blowing pipe is connected to the air source control box of the embedded patch type dripper screening machine through a corresponding air pipe. The guide plate 5 is composed of a plate body 53 and a baffle 52. A baffle 52 is fixedly installed on one side of the bottom of the plate body 53 along the length direction of the plate body 53. The bottom of the baffle 52 is placed on the bottom plate inside the cavity of the guide groove 10 of the lower ring body 2. The downward blowing oblique hole 51 is provided at the front of the plate body 53. A bolt hole 54 is provided in the middle of the plate body 53. The bolt passes through the bolt hole 54 on the plate body 53 and is connected and fixed to the upper ring body 1, thereby fixing the guide plate 5 on the inner wall of the upper ring body 1.

[0044] The widths of the inner ring outer track groove 6 and the outer ring outer track groove 7 are adapted to the width of the patch-type dripper, and the depths of the inner ring outer track groove 6 and the outer ring outer track groove 7 are adapted to the thickness of the patch-type dripper. The compressed gas in the inner ring air pipe connector 62 is ejected from the inner ring upper blowing oblique hole 61 and blown towards the lower plate surface of the patch-type dripper, causing the patch-type dripper to move forward in the inner ring outer track groove 6 cavity. The compressed gas in the outer ring air pipe connector 72 is ejected from the outer ring upper blowing oblique hole 71 and blown towards the lower plate surface of the patch-type dripper, causing the patch-type dripper to move forward in the outer ring outer track groove 7 cavity.

[0045] When using this utility model, it can be assembled onto the embedded patch-type dripper dual-track screening machine. When the embedded patch-type dripper dual-track screening machine is started to perform the patch-type dripper screening work, the PLC control box of the embedded patch-type dripper screening machine controls the air supply delivery status of each air pipe in the air source control box;

[0046] The flat-blowing hole 32 on the inner wall of the lower ring 2 corresponds to the inner track groove of the rotating track ring. The outer end of the flat-blowing hole 32 is connected to the flat-blowing pipe 31 installed in the flat-blowing pipe mounting hole 3. The compressed gas in the flat-blowing pipe 31 is blown through the flat-blowing hole 32 to the patch-type dripper in the inner track groove of the rotating track ring. The patch-type dripper that is in a qualified position remains stationary due to the blocking effect of the boss on the inner side of the inner track groove. The patch-type dripper that is not in a qualified position is blown out from the gap between the lower edge of the pressure ring and the upper plate surface of the rotating track ring. The purpose of this preliminary screening is to perform a rough and broad preliminary screening, which cannot guarantee complete accuracy. Due to the high rotation speed of the rotating track ring, it cannot be guaranteed that all the patch-type drippers with unqualified placement will be blown out. A small number of patch-type drippers with unqualified placement will be sent into the guide groove 10. The patch-type drippers are in the guide groove 10 below the guide plate 5. The compressed gas in the down-blowing pipe is ejected from the down-blowing inclined hole 51 and blown onto the upper plate surface of the patch-type drippers, causing them to move forward and enter the inner ring outer track groove 6.

[0047] At the inlet end of the inner ring outer track groove 6, the patch-type drippers pass sequentially through infrared probe 16 (number 2), the top-pressing device 8, the misplaced dripper removal device 9, and infrared probe 14 (number 1). If infrared probe 16 can detect the patch-type dripper but infrared probe 14 cannot, it indicates that a misplaced patch-type dripper is blocked by the stop block 97 of the misplaced dripper removal device 9. At this time, both infrared probes 16 and 14 transmit signals to the PLC control box of the embedded patch-type dripper sorting machine. The PLC control box controls the air source control box, first causing the pin 84 of the top-pressing device 8 to press down on the patch-type dripper below the top-pressing fixing seat 82, preventing it from moving forward, and then causing the sliding cover 94 of the misplaced dripper removal device 9 to retract. Opening the upper opening of the inner ring outer track groove 6 below the sliding cover 94 exposes the incorrectly positioned patch-type drippers that were blocked by the stop block 97. Then, the upward blowing connector 93 of the incorrectly positioned dripper removal device 9 is vented, and compressed gas is sprayed upward from the upward blowing hole 92, blowing the incorrectly positioned patch-type drippers out of the inner ring outer track groove 6, thus removing the incorrectly positioned patch-type drippers. After removing the incorrectly positioned patch-type drippers, the upward blowing connector 93 is no longer vented, and the removal cylinder 96 causes the sliding cover 94 of the incorrectly positioned dripper removal device 9 to extend and re-cover the inner ring outer track groove 6. Finally, the top pressure cylinder 83 is operated to retract the top pin 84 of the top pressure device 8, so that the patch-type drippers pressed under the top pin 84 can move forward and enter the incorrectly positioned dripper removal device 9 for inspection.

[0048] The correctly positioned dropper head enters the inner ring outer track groove 6 normally. Compressed gas in the inner ring air pipe connector 62 is ejected from the inner ring upward blowing hole 61 and blown onto the lower surface of the dropper head, causing the dropper head to move forward in the inner ring outer track groove 6 until it enters the outer ring outer track groove 7. Compressed gas in the outer ring air pipe connector 72 is ejected from the outer ring upward blowing hole 71 and blown onto the lower surface of the dropper head, causing the dropper head to move forward in the outer ring outer track groove 7 until it enters the track groove of the conveyor track. The dropper head is finally sent to the next process via the conveyor track. In this way, through the precise screening by the coordinated action of the second infrared probe 16, the top pressure device 8, the misplaced dropper head removal device 9, and the first infrared probe 14, it is ensured that all dropper heads are correctly positioned.
