Description

TECHNICAL FIELD

[0001] The present application relates to the field of drip irrigation tape production and manufacturing equipment, and particularly relates to an automatic up-down winding machine for drip irrigation tape. BACKGROUND

[0002] As a key tool for modern agricultural irrigation, drip irrigation tape has been widely used to greatly improve water resource utilization efficiency and crop yield. With the acceleration of agricultural modernization, efficient and reliable automated equipment has become an important guarantee for agricultural production. In particular, in large-scale planting scenarios, automated equipment not only greatly improves production efficiency, but also effectively reduces labor costs, ensuring the consistency and stability of product quality. However, despite the diversity of drip irrigation tape production equipment on the market, there are still some deficiencies that need to be further optimized and improved.

[0003] In existing drip irrigation tape production equipment, common automatic winding devices mostly adopt single-station design, i.e., completing the winding, cutting, and unwinding operations of drip irrigation tape at a fixed working position. Although this design scheme can realize basic automation functions, it exposes some problems in actual application. Specifically, such equipment is usually equipped with a fixed winding mechanism, and when a roll of drip irrigation tape is wound, the machine needs to be stopped for core replacement. In addition, some equipment uses manual or semi-automatic methods for core replacement, which not only increases the labor intensity of operators, but also seriously affects the production continuity and overall efficiency.

[0004] The main defect of the above common design scheme is the inability to quickly replace the core without stopping. Each time the machine is stopped for core replacement, the production is interrupted, which affects the running rhythm of the entire production line. Therefore, it is particularly important to develop an automatic up-down winding machine that can quickly replace the core without interrupting production. CONTENT OF THE INVENTION

[0005] In order to realize quick core replacement without interrupting production, the present application provides an automatic up-down winding machine for drip irrigation tape.

[0006] The automatic up-down winding machine for drip irrigation tape provided by the present application adopts the following technical scheme:

[0007] An automatic up-down winding machine for drip irrigation tape, comprising:

[0008] The automatic winding mechanism comprises a frame and a winding device, the frame is provided with a winding station and a preparation station, the winding device capable of winding drip irrigation tape is arranged on the winding station and the preparation station, the frame is connected with a rotating frame and a rotating device, the winding device of the winding station and the preparation station is connected with the rotating frame, the rotating device is located between the winding station and the preparation station and is connected with the rotating frame, and the rotating device is used for driving the rotating frame to turn over 180 degrees, wherein the winding device comprises a winding driving assembly and a winding core, the winding driving assembly is connected with the rotating frame, and the winding core is connected with the winding driving assembly and used for winding drip irrigation tape, and the frame is connected with a wire arranging device used for calculating the winding length of the drip irrigation tape.

[0009] The automatic core changing mechanism comprises a cutting device, a winding-off device and a core changing device, the cutting device is connected with the rotating frame and arranged between the winding station and the preparation station and used for cutting the drip irrigation tape, the winding-off device is used for taking off the winding core and the drip irrigation tape of the preparation station, and the core changing device is connected with the frame and used for mounting the winding core without winding drip irrigation tape to the winding device of the preparation station.

[0010] The feeding mechanism comprises a feeding frame, a plurality of fixing devices and a feeding driving device, the feeding frame is arranged on the side of the frame close to the preparation station, the feeding frame is provided with a feeding station, the core changing device can take the winding core at the feeding station, the feeding driving device is connected with the feeding frame and used for transporting the plurality of fixing devices to the feeding station in sequence, the fixing device comprises a first clamping jaw and a second clamping jaw, the first clamping jaw and the second clamping jaw are used for clamping two ends of the winding core, and the first clamping jaw and the second clamping jaw are both connected with the feeding driving device.

[0011] The control system is electrically connected with the automatic winding mechanism, the automatic core changing mechanism and the feeding mechanism.

[0012] By adopting the above technical solution, this automatic drip irrigation tape winding machine achieves automated production, improving work efficiency and reducing labor costs. Specifically, during operation, when the drip irrigation tape is fully wound and the core needs to be replaced, the control system first activates the rotating device, causing the rotating frame to rotate 180 degrees, thus exchanging the positions of the winding station and the standby station. At this time, the cutting device cuts the drip irrigation tape on the full winding station, and then the unwinding device removes the completed core from the standby station. Simultaneously, the core-changing device retrieves a new empty core from the feeding station and sends it to the winding drive assembly, which has now been converted to the standby station, ensuring continuous operation. The entire process requires no manual intervention, greatly improving the automation level and production efficiency of the equipment. In addition, the addition of the tape guide makes the winding of the drip irrigation tape more precise, avoiding the problem of material waste. Through the coordinated action of multiple fixing devices and the feeding drive device, the stability and reliability of the core supply are ensured. The entire system is uniformly managed by the control system, with each part operating in coordination, significantly reducing the failure rate and extending the service life of the equipment.

[0013] Preferably, the winding drive assembly includes a winding motor, a first bearing, a limiting plate, a fixed chuck, a winding cylinder, a movable chuck, and a second bearing. The winding motor is connected to the rotating frame, and the drive shaft of the winding motor passes through the rotating frame and is fixedly connected to the limiting plate. The first bearing is sleeved on the drive shaft of the winding motor and connected to the rotating frame. The fixed chuck is connected to the side wall of the limiting plate away from the winding motor. The winding cylinder is located on the side of the rotating frame away from the winding motor, and the drive shaft of the winding cylinder passes through the rotating frame and is connected to the movable chuck. The second bearing is located between the winding cylinder and the movable chuck, and is sleeved on the drive shaft of the winding cylinder. The outer wall of the second bearing is connected to the movable chuck. The movable chuck and the fixed chuck are correspondingly arranged to fix the winding core.

[0014] By adopting the above technical solution, during the winding process, the winding motor drives the limiting disc to rotate, which in turn drives the fixed chuck and the moving chuck to rotate synchronously, ensuring stable winding of the drip irrigation tape. Simultaneously, the first and second bearings reduce the friction on the drive shafts of the winding motor and the winding cylinder during rotation, improving transmission efficiency and service life. When the tape needs to be replaced, the winding cylinder extends or retracts, moving the moving chuck away from the fixed chuck, facilitating quick removal of a fully loaded tape and installation of a new empty tape, thus achieving efficient and continuous winding operations. The entire process is highly automated, greatly improving production efficiency and ease of operation.

[0015] Preferably, the limiting plate is connected to an auxiliary winding assembly, including a disassembly cylinder and a fixing ring. The disassembly cylinder is fixedly connected to the limiting plate. The drive shaft of the disassembly cylinder passes through the limiting plate and is connected to the fixing ring. The fixing ring is arranged around the fixed chuck and can abut against the winding core. When disassembling the winding core, the fixing ring can push the winding core away from the fixed chuck to realize the disassembly of the winding core.

[0016] By adopting the above technical solution, when the core needs to be disassembled, the retaining ring can push the core away from the retaining chuck under the action of the disassembly cylinder, thereby reducing the inconvenience and safety hazards caused by manual disassembly and improving disassembly efficiency and safety. At the same time, this design also reduces equipment downtime and improves production continuity and work efficiency.

[0017] Preferably, the unwinding device includes:

[0018] A horizontal drive assembly includes a support frame, a first motor, a first lead screw, and a movable frame. The first motor is connected to the support frame. The first lead screw is horizontally arranged and rotatably connected to the support frame. One end of the first lead screw is connected to the first motor. The movable frame is sleeved on the first lead screw and slidably connected to the support frame, enabling the horizontal movement of the movable frame.

[0019] A vertical drive assembly includes a second motor, a second lead screw, and a movable plate. The second motor is connected to the movable frame. The second lead screw is vertically positioned and rotatably connected to the movable frame. The second lead screw is connected to the second motor. The movable plate is sleeved on the second lead screw and slidably connected to the movable frame, enabling vertical movement of the movable plate.

[0020] A support component, connected to the movable plate, is used to support the drip tape and core at the preparatory station.

[0021] By adopting the above technical solution, precise positioning and stable operation of the unwinding device were achieved. The coordinated work of the horizontal and vertical drive components ensured the precise movement of the moving frame and moving plate in both horizontal and vertical directions, thereby effectively improving the automation level and work efficiency of the unwinding process. Simultaneously, the design of the support components ensured the stability of the drip irrigation tape and core during removal, preventing damage or detachment caused by shaking.

[0022] Preferably, the supporting component includes a first rod and a second rod, the first rod and the second rod are parallel to each other and are both connected to the movable plate, and the distance between the first rod and the second rod is less than the diameter of the drip irrigation tape after the core is wound.

[0023] By adopting the above technical solution, the first and second rods can ensure that the supporting components stably support the core when the core and drip tape are removed, eliminating the need for manual handling and improving the automation level and production efficiency of the equipment.

[0024] Preferably, the supporting assembly further includes a first cylinder, a second cylinder, a guide rod, a first slider, and a second slider. The first cylinder and the second cylinder are both connected to the movable plate. The guide rod is connected to the movable plate. The first slider and the second slider are both sleeved on the guide rod and slidably connected to it. The first slider is connected to the first cylinder, and the second slider is connected to the second cylinder. The movable plate has a first sliding hole and a second sliding hole. The length directions of the first sliding hole and the second sliding hole are parallel to the length direction of the guide rod. The first rod passes through the first sliding hole and is fixedly connected to the first slider. The second rod passes through the second sliding hole and is fixedly connected to the second slider. Both the first rod and the second rod are slidably connected to the movable plate, enabling adjustment of the distance between the first rod and the second rod.

[0025] By adopting the above technical solution, the support component can more flexibly adjust the positions of the first and second rods to accommodate drip irrigation tape cores of different diameters. Specifically, the first and second cylinders drive the first and second sliders to move along the guide rod, respectively, allowing the first and second rods to be precisely adjusted in the horizontal direction, ensuring that the core is not damaged due to positional deviation when being removed or placed. At the same time, this design improves the automation level of the equipment, reduces the need for manual intervention, and increases work efficiency.

[0026] Preferably, the core changing device includes a drive cylinder, a drive rod, and a mechanical claw. The drive cylinder is hinged to the frame, and the drive shaft of the drive cylinder is hinged to the drive rod. The first end of the drive rod is hinged to the frame, and the second end is connected to the mechanical claw. The drive cylinder enables the mechanical claw to pick up the core at the loading station or the winding device near the preparation station.

[0027] By adopting the above technical solution, the design of the drive cylinder and drive shaft allows the mechanical gripper to move flexibly between the loading station and the preparation station, thereby quickly and accurately picking up or placing the core. This design not only improves work efficiency but also reduces manual intervention, lowers labor intensity, and enhances the overall automation level of the equipment.

[0028] Preferably, the first and second grippers have the same structure, each including a mounting plate, a first clamping plate, a second clamping plate, a shaft, a spring, and a pressing handle. The mounting plate is connected to the feeding drive device, the first clamping plate is fixedly connected to the mounting plate, and the second clamping plate is rotatably connected to the first clamping plate via the shaft. A placement space for placing the core is formed between the first and second clamping plates. Both ends of the spring are fixedly connected to protrusions. The protrusion at the first end of the spring is connected to the first clamping plate, and the protrusion at the second end is connected to the second clamping plate, for cooperating the first and second clamping plates to clamp the core. The pressing handle is fixedly connected to the second clamping plate and is angled.

[0029] By adopting the above technical solution, the structural design of the first and second grippers allows the core to be securely clamped between the first and second clamping plates. Specifically, when the feeding mechanism needs to temporarily store multiple new cores, the operator presses the handle, causing the second clamping plate to rotate around the shaft, thereby expanding the placement space between the first and second clamping plates and allowing the core to be placed in. After releasing the handle, the first and second clamping plates fit tightly together under the action of the spring, ensuring the core is firmly clamped. When the core changing device retrieves the core, it can also be directly pulled out from between the first and second clamping plates. This design not only improves the convenience of core replacement but also ensures that the core will not fall off during transportation, enhancing the reliability and efficiency of the equipment.

[0030] Preferably, the feeding drive device includes a feeding motor, a feeding sprocket, and a feeding chain. The feeding motor is fixedly connected to the feeding frame. The feeding sprocket and the feeding chain form a feeding group. There are two feeding groups, which are arranged parallel to each other on both sides of the feeding frame and are both connected to the feeding frame. The first gripper and the second gripper correspond one-to-one with the two feeding groups. At least two feeding sprockets are provided in the same feeding group. The feeding sprockets are rotatably connected to the frame. The feeding chain is sleeved on at least two feeding sprockets in the same feeding group and meshes with at least two feeding sprockets. Any feeding sprocket is connected to the drive shaft of the feeding motor. The feeding sprockets in the two feeding groups rotate synchronously through a synchronous shaft. The mounting plate is connected to the feeding chain.

[0031] By adopting the above technical solution, the combined use of the feeding motor, feeding sprocket, and feeding chain can stably and efficiently transport multiple fixing devices sequentially to the feeding station, ensuring that each fixing device accurately reaches the predetermined position and clamps the core. This design not only improves the automation level of the equipment but also significantly enhances production efficiency and reliability.

[0032] Preferably, the feeding drive device is connected to a first sensor and a second sensor. The first sensor is located at the feeding station and is used to detect whether the fixing device located at the feeding station is clamping the core. The second sensor is located at the rear end of the feeding station and is used to detect whether there is still a core at the rear end of the feeding station.

[0033] By adopting the above technical solution, real-time monitoring of the loading station status is achieved. Specifically, the first sensor is located at the loading station, which can detect in a timely manner whether the fixing device has correctly clamped the core, ensuring the accuracy and reliability of the loading process. The second sensor is located at the rear end of the loading station, which can detect in advance whether there are cores to be loaded later, reducing the possibility of production interruption due to material shortage and improving equipment operating efficiency and continuity.

[0034] In summary, this utility model has the following beneficial effects:

[0035] This automatic drip irrigation tape winding machine achieves automated production, improving work efficiency and reducing labor costs. Specifically, during operation, when the drip irrigation tape is fully wound and the core needs to be replaced, the control system first activates the rotating device, causing the rotating frame to rotate 180 degrees, swapping the positions of the winding station and the standby station. At this point, the cutting device cuts the drip irrigation tape from the full winding station, and then the unwinding device removes the completed core from the standby station. Simultaneously, the core-changing device in the feeding mechanism retrieves a new empty core from the feeding station and delivers it to the newly converted standby winding drive assembly, ensuring continuous operation. The entire process requires no manual intervention, significantly improving the automation level and production efficiency of the equipment. Furthermore, the addition of a tape guide makes the winding of the drip irrigation tape more precise, avoiding material waste. The coordinated action of multiple fixing devices and the feeding drive device ensures the stability and reliability of the core supply. The entire system is uniformly managed by the control system, with each part operating in coordination, significantly reducing the failure rate and extending the equipment's service life.

[0053] An automatic drip irrigation tape unwinding and rewinding machine, as described in the reference. Figure 1 and Figure 2 The system includes an automatic winding mechanism, a wire guide 3, an automatic core changing mechanism, a feeding mechanism, and a control system. The automatic winding mechanism includes a frame 1 and a winding device 2. The frame 1 has a winding station 11 and a preparatory station 12, both equipped with winding devices 2 capable of winding drip irrigation tape. The frame 1 is connected to a rotating frame 13 and a rotating device 14. The winding devices 2 at both the winding station 11 and the preparatory station 12 are connected to the rotating frame 13. The rotating device 14 is connected to the rotating frame 13 and located between the winding station 11 and the preparatory station 12, used to rotate the rotating frame 13 by 180 degrees.

[0054] Reference Figure 3 and Figure 4 The winding device 2 includes a winding drive assembly 21 and a core 22. The winding drive assembly 21 is connected to the rotating frame 13, and the core 22 is connected to the winding drive assembly 21 for winding the drip irrigation tape. A cable guide 3 is connected to the frame 1 and is used to calculate the winding length of the drip irrigation tape. An automatic core-changing mechanism is used to remove the core 22 and drip irrigation tape from the preparatory station 12 and install the unwound core 22 onto the winding device 2 at the preparatory station 12. A feeding mechanism is used to store and sequentially transport multiple cores 22. The automatic winding mechanism, automatic core-changing mechanism, and feeding mechanism are all electrically connected to the control system.

[0055] During operation, when the core 22 at winding station 11 has finished winding the drip irrigation tape, it needs to be replaced. First, the control system activates the rotating device 14, causing the rotating frame 13 to rotate 180 degrees, thus exchanging the positions of winding station 11 and preparation station 12. Winding station 11 continues winding the drip irrigation tape, while the automatic core-changing mechanism removes the completed core 22 from preparation station 12 and retrieves a new empty core 22 from the feeding station 71, delivering it to the newly converted preparation station 12, ensuring continuous operation. The entire system is centrally managed by the control system, with coordinated operation of all parts, significantly reducing the failure rate and extending the equipment's service life.

[0056] Referring to 3, the rotating frame 13 is H-shaped and includes two winding spaces with openings on one side. The two winding spaces correspond one-to-one with the winding station 11 and the preparation station 12, respectively.

[0057] Reference Figure 3 The rotating device 14 includes a rotating shaft 141, a rotating motor 142, rotating sprockets 143, and a rotating chain 144. Two rotating shafts 141 are horizontally arranged, located on opposite sides of the rotating frame 13 away from the examination opening space, and are rotatably connected to the frame 1. The rotating motor 142 is fixedly connected to the frame 1 and located on one side of the rotating frame 13. Two rotating sprockets 143 are provided; one is fixedly connected to the drive shaft of the rotating motor 142, and the other is fixedly connected to the corresponding rotating shaft 141. The rotating chain 144 is sleeved on both rotating sprockets 143 and meshes with both sprockets 143.

[0058] After the rotary motor 142 is started, it can rotate the rotating frame 13 through the cooperation of two rotating sprockets 143 and rotating chain 144.

[0059] Reference Figure 3 and Figure 4 The winding drive assembly 21 includes a winding motor 211, a first bearing 212, a limiting plate 213, a fixed chuck 214, a winding cylinder 215, a movable chuck 216, and a second bearing 217. The winding motor 211 and the winding cylinder 215 are respectively located on both sides of the rotating frame 13, and both the winding motor 211 and the winding cylinder 215 are fixedly connected to the rotating frame 13.

[0060] Reference Figure 3 and Figure 4 The drive shaft of the winding motor 211 passes through the rotating frame 13 and is fixedly connected to the limiting plate 213. The limiting plate 213 is a circular plate-shaped body, which is vertically arranged and its axis coincides with the axis of the drive shaft of the winding motor 211. The first bearing 212 is sleeved on the bearing of the winding motor 211, and the outer wall of the first bearing 212 is fixedly connected to the rotating frame 13.

[0061] Reference Figure 4 The fixed chuck 214 includes a fixing part and a locking part, which are integrally formed. Both the fixing part and the locking part are circular plate-shaped bodies, with the diameter of the fixing part being larger than the diameter of the locking part. The fixed chuck 214 is vertically arranged, and the fixing part is fixedly connected to the limiting plate 213.

[0062] Reference Figure 3 and Figure 4 The movable chuck 216 has the same structure as the fixed chuck 214. The core 22 is a column with openings at both ends. The locking parts of both the fixed chuck 214 and the movable chuck 216 can be inserted into the hollow part of the core 22 to achieve clamping and limiting of the core 22. The drive shaft of the winding cylinder 215 passes through the rotating frame 13, and the second bearing 217 is sleeved on the drive shaft of the winding cylinder 215. The movable chuck 216 is fixedly connected to the outer wall of the second bearing 217.

[0063] During the winding process, the winding motor 211 drives the limiting disk 213 to rotate, which in turn drives the fixed chuck 214 and the moving chuck 216 to rotate synchronously, ensuring that the core 22 is stably wound around the drip irrigation tape. Simultaneously, the first bearing 212 and the second bearing 217 reduce the friction on the drive shaft of the winding motor 211 and the drive shaft of the winding cylinder 215 during rotation, respectively, improving transmission efficiency and service life. When the core 22 needs to be replaced, the winding cylinder 215 extends or retracts, moving the moving chuck 216 away from the fixed chuck 214, facilitating the quick removal of a fully loaded core 22 and the installation of a new empty core 22, thus achieving efficient and continuous winding operations. The entire process is highly automated, greatly improving production efficiency and ease of operation.

[0064] Reference Figure 2 and Figure 5 A horizontal moving component 31 is provided between the cable guide 3 and the frame 1 to drive the cable guide 3 to move sequentially along the axis of the core 22, so that the drip irrigation tape on the core 22 is wound evenly.

[0065] The horizontal moving assembly 31 includes a fixed frame 311, a moving motor 312, a moving screw 313, and a horizontal moving frame 314. The fixed frame 311 is fixedly connected to the frame 1. The moving motor 312 is fixedly connected to the fixed frame 311. Both ends of the moving screw 313 are rotatably connected to the fixed frame 311, and the length direction of the moving screw 313 is parallel to the axis of the winding core 22. One end of the moving screw 313 passes through the fixed frame 311 and is fixedly connected to the moving motor 312. The horizontal moving frame 314 is sleeved on the moving screw 313 and threadedly connected to it. The horizontal moving frame 314 slidably abuts against the fixed frame 311. The support plate of the cable guide 3 is fixedly connected to the horizontal moving frame 314.

[0066] During the drip irrigation tape winding process, the moving motor 312 is started, which drives the moving screw 313 to rotate. The moving screw 313 drives the horizontal moving frame 314 to move, which in turn drives the wire guide 3 to move, so that the drip irrigation tape is evenly wound in the length direction of the core 22.

[0067] Reference Figure 5 The drip irrigation tape 3 includes two parallel support plates and multiple rollers, all positioned between the two support plates and rotatably connected to them. In this embodiment, four rollers are provided, not aligned in a straight line, and the drip irrigation tape is sequentially wound around the four rollers. The drip irrigation tape 3 is connected to a counter 32. The receiver of the counter 32 is fixedly connected to any one of the support plates, and the transmitter of the counter 32 is fixedly connected to any one of the rollers. Each time a roller rotates, the receiver of the counter 32 receives a signal once, and the counter 32 increments by one.

[0068] Reference Figure 5 A horizontal axis is rotatably connected to the horizontal moving frame 314. A torsion spring is sleeved on the horizontal axis, with one end of the torsion spring fixedly connected to the horizontal axis and the other end fixedly connected to the horizontal moving frame 314. An extension rod is fixedly connected to the horizontal axis, and a limit ring is fixedly connected to the top of the extension rod. The limit rings are spaced apart. The drip irrigation tape wound from the roller passes through each limit ring and is wrapped around the core 22.

[0069] Reference Figure 3 and Figure 6 The automatic core-changing mechanism includes a cutting device 4, a winding device 5, and a core-changing device 6. The cutting device 4 includes a cutting assembly 41 and an end-stopping assembly 42. The cutting assembly 41 is positioned between the preparatory station 12 and the winding station 11, and is connected to the middle of the rotating frame 13.

[0070] Reference Figure 6 The cutting assembly 41 includes a cutting blade 411, a cutting cylinder 412, a rack 413, a gear 414, a rotating rod 415, and a push rod 416. The cutting blade 411, rack 413, gear 414, rotating rod 415, and push rod 416 form an implementation group, and there are two implementation groups.

[0071] Reference Figure 3 and Figure 6 The cutting blade 411 is vertically positioned and fixedly connected to the rotating frame 13, with each of the two cutting blades 411 corresponding to one of the two limiting discs 213. The blades of both cutting blades 411 protrude from the rotating frame 13, with the blade of the cutting blade 411 located at the preparatory station 12 facing downwards and the blade of the cutting blade 411 located at the winding station 11 facing upwards.

[0072] ReferenceFigure 6 The cutting cylinder 412 is horizontally positioned and fixedly connected to the rotating frame 13. The extension and retraction direction of the drive shaft of the cutting cylinder 412 is parallel to the axis of the core 22. The rack 413 is horizontally positioned, with two racks 413 fixedly connected to each other on their sidewalls away from each other. One end of each rack 413 on the same side is fixedly connected to the cutting cylinder 412. The rotating rod 415 is horizontally positioned, with both ends fixedly connected to the rotating frame 13. The length direction of the rotating rod 415 is perpendicular to the axis of the core 22. The rotating rod 415 is located on the side of the rotating frame 13 near the limiting disc 213, with the two rotating rods 415 positioned above and below the rack 413, respectively.

[0073] Within the same implementation group, gear 414 is sleeved on rotating rod 415 and fixedly connected to rotating rod 415. Gear 414 meshes with rack 413. One end of push rod 416 is fixedly connected to rotating rod 415. The end of push rod 416 away from rotating rod 415 is provided with a bend.

[0074] When it is necessary to cut the drip irrigation tape at the preparatory station 12, the cutting cylinder 412 is activated. The cutting cylinder 412 drives the cutting rack 413 to move, the cutting rack 413 drives the cutting gear 414 to rotate, and the cutting gear 414 drives the push rod 416 to rotate through the rotating rod 415. The push rod 416 pushes the drip irrigation tape to the side with the cutting blade 411, and the cutting blade 411 cuts the drip irrigation tape. The cut drip irrigation tape is then wrapped around the core 22 of the winding station 11.

[0075] Reference Figure 6 and Figure 7 The end-positioning component 42 includes a limiting cylinder 421, a limiting frame 422, a vertical shaft 423, a movable rod 424, a movable plate 425, and a vertical plate 426. The limiting cylinder 421 is fixedly connected to the side wall of the limiting disc 213 away from the fixed chuck 214. The limiting frame 422 is fixedly connected to the limiting disc 213, and the vertical shaft 423 and the vertical plate 426 are both fixedly connected to the limiting frame 422. The movable rod 424 is sleeved on the vertical shaft 423 and rotatably connected to the vertical shaft 423. One end of the movable rod 424 is fixedly connected to the limiting cylinder 421, and the other end is fixedly connected to the movable plate 425.

[0076] Reference Figure 6 and Figure 7 The vertical plate 426 is vertically positioned, with its vertical surface perpendicular to the vertical surface of the limiting plate 213. The top surface of the vertical plate 426 is curved, extending from the edge away from the winding motor 211 towards the other end. The movable plate 425 is also curved, with its center near the movable rod 424. The side wall of the movable plate 425 near the vertical plate 426 has anti-slip textures. When the movable plate 425 abuts against the vertical plate 426, it clamps the drip irrigation tape.

[0077] The push rod 416 can push the drip tape located at any position on the core 22 to the end limiting component 42 on the limiting plate 213. Due to the arc setting at the top of the vertical plate 426, the drip tape can slide into the space between the vertical plate 426 and the movable plate 425. The limiting cylinder 421 is activated and retracted, causing the movable rod 424 to rotate around the vertical axis 423, thereby bringing the movable plate 425 closer to the vertical plate 426, thus achieving the clamping of the drip tape.

[0078] Reference Figure 2 and Figure 8 The unwinding device 5 includes a horizontal drive assembly 51, a vertical drive assembly 52, a support assembly 53, an auxiliary unwinding assembly 54, and a conveying device 55.

[0079] The horizontal drive assembly 51 includes a support frame 511, a first motor 512, a first lead screw 513, and a movable frame 514. The support frame 511 is located near the machine frame 1 and close to the preparatory station 12. The first motor 512 is fixedly connected to the support frame 511. The first lead screw 513 is horizontally arranged, with both ends of the first lead screw 513 rotatably connected to the support frame 511. One end of the first lead screw 513 passes through the support frame 511 and is fixedly connected to the first motor 512. The movable frame 514 is sleeved on the first lead screw 513 and threadedly connected to the first lead screw 513. The movable frame 514 slides against the support frame 511, enabling horizontal movement of the movable frame 514.

[0080] Start the first motor 512, which drives the first lead screw 513 to rotate. The first lead screw 513 drives the moving frame 514 to move. Since the first lead screw 513 is set horizontally, the moving frame 514 can move in the horizontal direction.

[0081] Reference Figure 2 and Figure 8 The vertical drive assembly 52 includes a second motor 521, a second lead screw 522, and a moving plate 523. The second motor 521 is fixedly connected to the moving frame 514. The second lead screw 522 is vertically arranged, with both ends rotatably connected to the moving frame 514. One end of the second lead screw 522 passes through the moving frame 514 and is fixedly connected to the second motor 521. The moving plate 523 is sleeved on the second lead screw 522 and threadedly connected to it. The moving plate 523 slides against the moving frame 514, enabling the moving plate 523 to move vertically.

[0082] Start the second motor 521, which drives the second lead screw 522 to rotate, and the second lead screw 522 drives the moving plate 523 to move in the vertical direction.

[0083] Reference Figure 8 and Figure 9The supporting component 53 includes a first rod 531, a second rod 532, a first cylinder 533, a second cylinder 534, a guide rod 535, a first slider 536, and a second slider 537. The moving plate 523 has a first sliding hole 5231 and a second sliding hole 5232, both horizontally oriented along their lengths, and located on the same horizontal plane. The first rod 531 and the second rod 532 are both horizontally oriented, and their lengths are perpendicular to the moving plate 523. The first rod 531 passes through the first sliding hole 5231 and is fixedly connected to the first slider 536; the second rod 532 passes through the second slider 537 and is fixedly connected to the second slider 537.

The guide rod 535 is horizontally positioned and fixedly connected to the moving plate 523. The first slider 536 and the second slider 537 are both sleeved on the guide rod 535 and are slidably connected to the guide rod 535. The first slider 536 is fixedly connected to the first cylinder 533, and the second slider 537 is fixedly connected to the second cylinder 534.

[0085] During its movement, the movable plate 523 drives the supporting assembly 53 to move, thereby enabling the first rod 531 and the second rod 532 to stably support the drip irrigation tape. Furthermore, the first cylinder 533 and the first slider 536 work together to drive the first rod 531 to slide within the first sliding hole 5231, and the second cylinder 534 and the second slider 537 work together to drive the second rod 532 to slide within the first sliding hole 5231. Adjusting the distance between the first rod 531 and the second rod 532 allows for the adaptation of cores 22 wound with drip irrigation tape of different lengths.

[0086] Reference Figure 4 and Figure 7 The auxiliary unwinding assembly 54 includes a disassembly cylinder 541 and a retaining ring 542. Two disassembly cylinders 541 are provided, both fixedly connected to the limiting plate 213. The retaining ring 542 is located around the fixed chuck 214, and its thickness is less than the thickness of the fixed chuck 214. The drive shaft of the disassembly cylinder 541 passes through the limiting plate 213 and is fixedly connected to the retaining ring 542.

[0087] When it is necessary to replace or remove the core 22, the disassembly cylinder 541 is activated, which drives the fixing ring 542 to push the core 22 away from the fixing chuck 214, thereby removing the core 22.

[0088] Reference Figure 2 and Figure 8The conveying device 55 is a belt conveyor. The inlet end of the conveying device 55 is close to the horizontal drive assembly 51, and the first rod 531 and the second rod 532 can place the wound drip irrigation tape onto the conveying device 55.

[0089] Reference Figure 10 The core-changing device 6 includes a drive cylinder 61, a drive rod 62, and a mechanical gripper 63. One end of the drive cylinder 61 is hinged to the frame 1, and the other end is hinged to the drive rod 62. One end of the drive rod 62 is hinged to the frame 1, and the other end is connected to the mechanical gripper 63.

[0090] The design of the drive cylinder 61 and drive shaft allows the mechanical claw 63 to move flexibly between the loading station 71 and the preparation station 12, thereby quickly and accurately picking up or placing the core 22.

[0091] Reference Figure 10 The mechanical gripper 63 includes a first gripper 631, a first driven rod 632, a first mounting rod 633, a first core-changing cylinder 634, a second gripper 635, a second driven rod 636, a second mounting rod 637, and a second core-changing cylinder 638. One end of the first driven rod 632 is hinged to the drive rod 62, and the other end is fixedly connected to the first gripper 631. The first mounting rod 633 is connected to the side wall of the drive rod 62, and the first core-changing cylinder 634 is hinged to the first mounting rod 633, leaving a distance between the first core-changing cylinder 634 and the drive rod 62. The drive shaft of the first core-changing cylinder 634 is hinged to the first gripper 631.

[0092] Reference Figure 3 and Figure 10 One end of the second driven rod 636 is hinged to the drive rod 62, and the other end is fixedly connected to the second claw 635. The second mounting rod 637 is connected to the side wall of the drive rod 62, and the second core-changing cylinder 638 is hinged to the second mounting rod 637, leaving a distance between the second core-changing cylinder 638 and the drive rod 62. The drive shaft of the second core-changing cylinder 638 is hinged to the second claw 635. The second claw 635 and the first claw 631 are symmetrically arranged, and the two cooperate to clamp the core 22.

[0093] When the mechanical gripper 63 is used, the first core-changing cylinder 634 and the second core-changing cylinder 638 are activated. The first core-changing cylinder 634 retracts, causing the first driven rod 632 to rotate, moving the first gripper 631 away from the second gripper 635. The second core-changing cylinder 638 retracts, causing the second driven rod 636 to rotate, moving the second gripper 635 away from the first gripper 631, thus opening the mechanical gripper 63. Conversely, when both the first core-changing cylinder 634 and the second core-changing cylinder 638 extend, the first gripper 631 and the second gripper 635 move closer to each other, thereby clamping the mechanical gripper 63 and holding the core 22.

[0094] Reference Figure 1 andFigure 11 The feeding mechanism includes a feeding rack 7, a fixing device 8, and a feeding drive device 9. The feeding rack 7 is located near the frame 1 and close to the preparation station 12. The feeding station 71 is located at one end of the feeding rack close to the frame 1, which facilitates the mechanical claw 63 to grasp the core.

[0095] Reference Figure 12 The feeding rack 7 is connected to a first sensor 72 and a second sensor 73. The first sensor 72 is located at the feeding station 71 and is used to detect whether the fixing device 8 located at the feeding station 71 is clamping the core 22. The second sensor 73 is located at the rear end of the feeding station 71 and is used to detect whether there is still a core 22 at the rear end of the feeding station 71.

[0096] Reference Figure 11 and Figure 12 The feeding drive device 9 includes a feeding motor 91, a feeding sprocket 92, and a feeding chain 93. The feeding motor 91 is fixedly connected to the feeding frame 7. Two feeding sprockets 92 and feeding chains 93 form a feeding group, and two feeding groups are provided, which are arranged parallel to each other on both sides of the feeding frame 7. The two feeding sprockets 92 in the same feeding group are located at the two ends of the feeding frame 7, and the two feeding sprockets 92 at the same end of the feeding frame 7 rotate synchronously through a synchronous shaft.

[0097] The feeding chain 93 is fitted onto two feeding sprockets 92 within the same feeding group and meshes with both feeding sprockets 92. The drive shaft of the feeding motor 91 passes through and is fixedly connected to either feeding sprocket 92. Multiple fixing devices 8 are provided and are arranged at intervals along the feeding chain 93.

[0098] Start the feeding motor 91, which drives the feeding sprocket 92 to rotate. The feeding sprocket 92 drives the feeding chain 93 to move, which can stably and efficiently transport multiple fixing devices 8 to the feeding station 71 in sequence, ensuring that each fixing device 8 can accurately reach the predetermined position and clamp the core 22.

[0099] Reference Figure 11 The specific number of fixing devices 8 is determined according to the actual situation to improve manual work efficiency. The fixing device 8 includes a first gripper 81 and a second gripper 82, which correspond one-to-one with two feeding chains 93.

[0100] Reference Figure 12The first gripper 81 and the second gripper 82 have the same structure, both including a mounting plate 811, a first clamping plate 812, a second clamping plate 813, a shaft 814, a spring 815, and a pressing handle 816. The mounting plate 811 is fixedly connected to the feeding chain 93, the first clamping plate 812 is fixedly connected to the mounting plate 811, and the second clamping plate 813 is rotatably connected to the first clamping plate 812 via the shaft 814. The shaft 814 is horizontally positioned, and the spring 815 is horizontally positioned. Both ends of the spring 815 are fixedly connected to protrusions. The protrusion at the first end of the spring 815 is fixedly connected to the first clamping plate 812, and the protrusion at the second end is fixedly connected to the second clamping plate 813, so that a space for clamping the core 22 is formed between the first clamping plate 812 and the second clamping plate 813.

[0101] Reference Figure 12 The pressing handle 816 is fixedly connected to the second clamping plate 813, and there is an angle between the pressing handle 816 and the second clamping plate 813, which makes it easy to hold the pressing handle 816 and increases the opening of the space formed by the first clamping plate 812 and the second clamping plate 813, making it easier to put the core 22 in.

[0102] In this embodiment, the rotary motor 142, winding motor 211, winding cylinder 215, moving motor 312, cutting cylinder 412, limiting cylinder 421, first motor 512, second motor 521, first cylinder 533, second cylinder 534, disassembly cylinder 541, drive cylinder 61, first core-changing cylinder 634, second core-changing cylinder 638, and feeding motor 91 are all electrically connected to the control system.

[0103] The operating principle of this application is as follows: The drip irrigation tape is sequentially wound onto multiple rollers of the cable guide 3, then passes through the limiting ring on the extension rod, and is wound onto the core 22 of the winding station 11. When the core 22 of the winding station 11 is finished winding the drip irrigation tape, it needs to be replaced. First, the control system starts the rotating device 14, which drives the rotating frame 13 to rotate 180 degrees, so that the positions of the winding station 11 and the preparation station 12 are interchanged. Then, the cutting device 4 cuts the drip irrigation tape on the full winding station 11, and the unwinding device 5 then moves to remove the completed core 22 from the preparation station 12. At the same time, the core changing device 6 in the feeding mechanism picks up a new empty core 22 at the feeding station 71 and sends it to the winding drive assembly 21, which has now been converted to the preparation station 12, to ensure continuous operation. The entire process requires no manual intervention, which greatly improves the automation level and production efficiency of the equipment. Furthermore, the addition of counter 32 on the cable guide 3 makes the wrapping of the drip irrigation tape more precise, avoiding material waste. The coordinated action of multiple fixing devices 8 and the feeding drive device 9 ensures the stability and reliability of the core 22 supply. The entire system is uniformly managed by the control system, with each part operating in coordination, significantly reducing the failure rate and extending the equipment's service life.

[0104] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
