Description

Technical Field

[0001] This application relates to the field of drip irrigation tape production and manufacturing equipment, and particularly to an automatic upper and lower coiling machine for drip irrigation tapes. Background Art

[0002] As a key tool for modern agricultural irrigation, drip irrigation tapes have been widely used, greatly improving the water resource utilization efficiency and crop yields. With the acceleration of the agricultural modernization process, efficient and reliable automated equipment has become an important guarantee for agricultural production. Especially in large-scale planting scenarios, automated equipment not only significantly improves production efficiency but also effectively reduces labor costs, ensuring the consistency and stability of product quality. However, despite the availability of diverse drip irrigation tape production equipment in 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 a single-station design, that is, the winding, cutting, and unwinding operations of the drip irrigation tape are completed at a fixed working position. Although this design can achieve basic automation functions, some problems have emerged in practical applications. Specifically, such equipment usually has a fixed winding mechanism. When a roll of drip irrigation tape is wound up, it is necessary to stop the machine for core replacement. In addition, some equipment uses manual or semi-automatic methods for core replacement, which not only increases the labor intensity of the operators but also seriously affects production continuity and overall efficiency.

[0004] The main defect of the above common design is that it cannot achieve rapid core replacement without stopping the machine. Each time the machine stops for core replacement, production will be interrupted, thus affecting the operation rhythm of the entire production line. Therefore, it is particularly important to develop an automatic upper and lower coiling machine for drip irrigation tapes that can achieve rapid core replacement during continuous production. Summary of the Invention

[0005] In order to achieve rapid core replacement during continuous production, the present invention provides an automatic upper and lower coiling machine for drip irrigation tapes.

[0006] The automatic upper and lower coiling machine for drip irrigation tapes provided by the present invention adopts the following technical solutions: An automatic upper and lower coiling machine for drip irrigation tapes, comprising: Automatic winding mechanism, comprising a frame and a winding device. The frame is provided with a winding station and a preparatory station. The winding device capable of winding the drip irrigation tape is provided at both the winding station and the preparatory station. The frame is connected with a rotating frame and a rotating device. The winding devices at the winding station and the preparatory station are both connected with the rotating frame. The rotating device is located between the winding station and the preparatory station and is connected with the rotating frame for driving the rotating frame to flip 180 degrees. Among them, the winding device includes a winding drive assembly and a core. The winding drive assembly is connected with the rotating frame, and the core is connected with the winding drive assembly for winding the drip irrigation tape. The frame is connected with a wire arranging device for calculating the winding length of the drip irrigation tape; Automatic core-changing mechanism, comprising a cutting device, a lower-winding device and a core-changing device. The cutting device is connected with the rotating frame and is arranged between the winding station and the preparatory station for cutting the drip irrigation tape. The lower-winding device is used for removing the core and the drip irrigation tape at the preparatory station. The core-changing device is connected with the frame for installing the core without the drip irrigation tape wound thereon onto the winding device at the preparatory station; Feeding mechanism, comprising a feeding rack, a plurality of fixing devices and a feeding drive device. The feeding rack is arranged on one side of the frame close to the preparatory station. The feeding rack is provided with a feeding station. The core-changing device can pick up the core at the feeding station. The feeding drive device is connected with the feeding rack for sequentially transporting the plurality of fixing devices to the feeding station. The fixing device includes a first jaw and a second jaw. The first jaw and the second jaw are used for clamping both ends of the core. Both the first jaw and the second jaw are connected with the feeding drive device; and Control system. The automatic winding mechanism, the automatic core-changing mechanism and the feeding mechanism are all electrically connected with the control system.

[0007] By adopting the above technical solutions, the automatic upper and lower coiling machine for drip irrigation tapes realizes automated production, improves work efficiency and reduces labor costs. Specifically, during use, when the drip irrigation tape has been wound enough and the core needs to be replaced, first, the control system starts the rotating device, driving the rotating frame to flip 180 degrees, so that the positions of the winding station and the preparation station are interchanged. At this time, the cutting device cuts the drip irrigation tape on the full winding station, and then the lower coiling device operates to take out the core that has completed winding from the preparation station. At the same time, the core changing device picks up a new empty core at the feeding station and sends it to the winding drive assembly that has been newly converted into the preparation station to ensure 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 wire arranging device 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, and each part operates in coordination, significantly reducing the failure rate and extending the service life of the equipment.

[0008] Preferably, the winding drive assembly includes a winding motor, a first bearing, a limit disk, 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 limit disk. The first bearing is sleeved on the drive shaft of the winding motor and is connected to the rotating frame. The fixed chuck is connected to the side wall of the limit disk away from the winding motor. The winding cylinder is arranged on the side of the rotating frame away from the winding motor. The drive shaft of the winding cylinder passes through the rotating frame and is connected to the movable chuck. The second bearing is arranged between the winding cylinder and the movable chuck. The inner ring of the second bearing is sleeved on the drive shaft of the winding cylinder, and the outer wall of the second bearing is connected to the movable chuck. The movable chuck is arranged corresponding to the fixed chuck for fixing the core.

[0009] By adopting the above technical solutions, during winding, the winding motor drives the limit disk to rotate, thereby driving the fixed chuck and the movable chuck to rotate synchronously to ensure the stable winding of the core with the drip irrigation tape. At the same time, the first bearing and the second bearing respectively reduce the friction of the drive shaft of the winding motor and the drive shaft of the winding cylinder during rotation, improving the transmission efficiency and service life. When the core needs to be replaced, the winding cylinder expands and contracts, causing the movable chuck to move away from the fixed chuck, facilitating the quick removal of the fully loaded core and the installation of a new empty core, thus realizing efficient and continuous winding operation. The entire process has a high degree of automation, greatly improving production efficiency and operation convenience.

[0010] Preferably, the limiting disk is connected with an auxiliary uncoiling component, which includes a disassembling cylinder and a fixing ring. The disassembling cylinder is fixedly connected with the limiting disk. The driving shaft of the disassembling cylinder passes through the limiting disk and is connected with the fixing ring. The fixing ring is arranged around the fixed chuck and can abut against the core. When disassembling the core, the fixing ring can push the core away from the fixed chuck to realize the disassembly of the core.

[0011] By adopting the above technical solution, when it is necessary to disassemble the core, the fixing ring can push the core away from the fixed chuck under the action of the disassembling cylinder, thereby reducing the inconvenience and potential safety hazards brought by manual disassembly, improving the disassembly efficiency and safety. At the same time, this design also reduces the equipment downtime and improves the production continuity and work efficiency.

[0012] Preferably, the uncoiling device includes: A horizontal driving component, including a support frame, a first motor, a first lead screw and a moving frame. The first motor is connected with the support frame. The first lead screw is horizontally arranged and rotatably connected with the support frame. One end of the first lead screw is connected with the first motor. The moving frame is sleeved on the first lead screw and is slidably connected with the support frame, capable of realizing the horizontal movement of the moving frame; A vertical driving component, including a second motor, a second lead screw and a moving plate. The second motor is connected with the moving frame. The second lead screw is vertically arranged and rotatably connected with the moving frame. The second lead screw is connected with the second motor. The moving plate is sleeved on the second lead screw and is slidably connected with the moving frame, capable of realizing the vertical movement of the moving plate; and A supporting component, connected with the moving plate, for supporting the drip irrigation tape and the core at the preparation station.

[0013] By adopting the above technical solution, the accurate positioning and stable operation of the uncoiling device are realized. The coordinated work of the horizontal driving component and the vertical driving component ensures the precise movement of the moving frame and the moving plate in the horizontal and vertical directions, thereby effectively improving the automation degree and work efficiency of the uncoiling process. At the same time, the design of the supporting component makes the drip irrigation tape and the core remain stable during the removal process, avoiding damage or detachment caused by shaking.

[0014] 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 with the moving plate. The distance between the first rod and the second rod is less than the diameter of the core after the drip irrigation tape is wound around the core.

[0015] By adopting the above technical solution, the first rod and the second rod can ensure that the supporting component stably supports the core when removing the core and the drip irrigation tape, eliminating the need for manual handling, and improving the automation degree and production efficiency of the equipment.

[0016] Preferably, the supporting component 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 moving plate. The guide rod is connected to the moving plate. The first slider and the second slider are both sleeved on the guide rod and are both slidably connected to the guide rod. The first slider is connected to the first cylinder, and the second slider is connected to the second cylinder. A first sliding hole and a second sliding hole are formed in the moving plate. The length directions of the first sliding hole and the second sliding hole are both 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. The first rod and the second rod are both slidably connected to the moving plate, and the distance between the first rod and the second rod can be adjusted.

[0017] By adopting the above technical solution, the supporting component can more flexibly adjust the positions of the first rod and the second rod, so as to adapt to drip irrigation tape cores with different diameters. Specifically, the first cylinder and the second cylinder respectively drive the first slider and the second slider to move along the guide rod, so that the first rod and the second rod can be precisely adjusted in the horizontal direction, ensuring that the core will not be damaged due to position deviation when removing or placing the core. At the same time, this design improves the automation degree of the equipment, reduces the need for manual intervention, and improves the work efficiency.

[0018] Preferably, the core changing device includes a driving cylinder, a driving rod, and a mechanical claw. The driving cylinder is hinged to the frame. The driving shaft of the driving cylinder is hinged to the driving rod. The first end of the driving rod is hinged to the frame, and the second end is connected to the mechanical claw. The driving cylinder can enable the mechanical claw to pick up the core at the loading station or approach the winding device at the preparation station.

[0019] By adopting the above technical solution, the design of the driving cylinder and the driving shaft enables the mechanical claw to move flexibly between the loading station and the preparation station, so as to quickly and accurately pick up or place the core. This design not only improves the work efficiency, but also reduces the manual intervention, reduces the labor intensity, and improves the overall automation degree of the equipment.

[0020] Preferably, the first clamping jaw and the second clamping jaw have the same structure, and both include a mounting plate, a first clamping plate, a second clamping plate, a shaft rod, a spring and a pressing handle. The mounting plate is connected to the feeding driving device. The first clamping plate is fixedly connected to the mounting plate. The second clamping plate is rotatably connected to the first clamping plate through the shaft rod. A placing space for placing the core is formed between the first clamping plate and the second clamping plate. Both ends of the spring are fixedly connected with bumpers. The bumper at the first end of the spring is connected to the first clamping plate, and the bumper at the second end is connected to the second clamping plate, so as to enable the first clamping plate and the second clamping plate to cooperate to clamp the core. The pressing handle is fixedly connected to the second clamping plate and is arranged at an angle.

[0021] By adopting the above technical solution, the structural design of the first clamping jaw and the second clamping jaw enables the core to be firmly clamped between the first clamping plate and the second clamping plate. Specifically, when the feeding mechanism needs to temporarily store multiple new cores, the operator presses the pressing handle to make the second clamping plate rotate around the shaft rod, thereby expanding the placing space between the first clamping plate and the second clamping plate, and placing the core. After releasing the pressing handle, under the action of the spring, the first clamping plate and the second clamping plate are closely attached to ensure that the core is firmly clamped. When the core-changing device takes the core, the core can also be directly pulled out from between the first clamping plate and the second clamping plate. 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 working efficiency of the equipment.

[0022] Preferably, the feeding driving 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, and the two feeding groups are arranged in parallel on both sides of the feeding frame and are both connected to the feeding frame. The first clamping jaw and the second clamping jaw respectively correspond to the two feeding groups one by one. There are at least two feeding sprockets in the same feeding group. The feeding sprocket is rotatably connected to the machine 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 one of the feeding sprockets is connected to the driving shaft of the feeding motor. The feeding sprockets in the two feeding groups rotate synchronously through a synchronizing shaft. The mounting plate is connected to the feeding chain.

[0023] By adopting the above technical solution, the combined use of the feeding motor, the feeding sprocket and the feeding chain can stably and efficiently transport multiple fixing devices to the feeding station in sequence, ensuring that each fixing device can accurately reach the predetermined position and clamp the core. This design not only improves the automation degree of the equipment, but also significantly enhances the production efficiency and reliability.

[0024] Preferably, the feeding driving device is connected with a first sensor and a second sensor. The first sensor is arranged at the feeding station and is used for detecting whether the fixing device at the feeding station clamps the core. The second sensor is arranged at the rear end of the feeding station and is used for detecting whether there is still a core at the rear end of the feeding station.

[0025] By adopting the above technical solution, the real-time monitoring of the state of the feeding station is realized. Specifically, the first sensor is arranged at the feeding station and can timely detect whether the fixing device has correctly clamped the core, ensuring the accuracy and reliability of the feeding process. The second sensor is arranged at the rear end of the feeding station and can sense in advance whether there is a core to be fed subsequently, reducing the possibility of production interruption caused by material shortage and improving the operation efficiency and continuity of the equipment.

[0026] In summary, the present invention has the following beneficial effects: The automatic upper and lower coiling machine for drip irrigation tapes realizes automated production, improves work efficiency and reduces labor costs. Specifically, during use, when the drip irrigation tape is wound enough and the core needs to be replaced, first, the control system starts the rotating device to drive the rotating frame to flip 180 degrees, so that the positions of the winding station and the preparation station are interchanged. At this time, the cutting device cuts the drip irrigation tape on the full winding station, and then the lower coiling device acts to take out the wound core from the preparation station. At the same time, the core-changing device in the feeding mechanism takes a new empty core at the feeding station and sends it to the winding drive assembly that has been newly converted into the preparation station to ensure continuous operation. The whole process does not require manual intervention, greatly improving the automation degree and production efficiency of the equipment. In addition, the addition of the wire arranging device 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 driving device, the stability and reliability of the core supply are ensured. The whole system is uniformly managed by the control system, and each part operates in coordination, significantly reducing the failure rate and extending the service life of the equipment.

[0043] An automatic upper and lower coiling machine for drip irrigation tapes, referring to Figure 1 and Figure 2 , comprises an automatic winding mechanism, a wire arranging device 3, an automatic core changing mechanism, a feeding mechanism and a control system. The automatic winding mechanism comprises a frame 1 and a winding device 2. The frame 1 is provided with a winding station 11 and a preparation station 12, and winding devices 2 capable of winding drip irrigation tapes are arranged at both the winding station 11 and the preparation station 12. The frame 1 is connected with a rotating frame 13 and a rotating device 14, and the winding devices 2 at the winding station 11 and the preparation station 12 are both connected with the rotating frame 13. The rotating device 14 is connected with the rotating frame 13 and is located between the winding station 11 and the preparation station 12, and is used for driving the rotating frame 13 to flip 180 degrees.

[0044] Referring to Figure 3 and Figure 4 , the winding device 2 comprises a winding drive assembly 21 and a core 22. The winding drive assembly 21 is connected with the rotating frame 13, and the core 22 is connected with the winding drive assembly 21 and is used for winding the drip irrigation tape. The wire arranging device 3 is connected with the frame 1 and is used for calculating the winding length of the drip irrigation tape. The automatic core changing mechanism is used for removing the core 22 and the drip irrigation tape at the preparation station 12 and installing the core 22 without the wound drip irrigation tape onto the winding device 2 at the preparation station 12. The feeding mechanism is used for storing and sequentially transporting a plurality of cores 22. The automatic winding mechanism, the automatic core changing mechanism and the feeding mechanism are all electrically connected with the control system.

[0045] During the operation, when the core 22 at the winding station 11 finishes winding the drip irrigation tape, the core 22 needs to be replaced. First, the control system starts the rotating device 14 to drive the rotating frame 13 to flip 180 degrees, so that the positions of the winding station 11 and the preparation station 12 are interchanged. The winding station 11 continues to wind the drip irrigation tape. The automatic core-changing mechanism takes out the wound core 22 from the preparation station 12, picks up a new empty core 22 at the loading station 71, and sends it to the winding drive assembly 21 that has been newly converted to the preparation station 12 to ensure continuous operation. The entire system is uniformly managed by the control system, and each part operates coordinately, significantly reducing the failure rate and extending the service life of the equipment.

[0046] Referring to FIG. 3, the rotating frame 13 is in an H shape and includes two winding spaces with one side open. The two winding spaces respectively correspond to the winding station 11 and the preparation station 12 one by one.

[0047] Referring to Figure 3 , the rotating device 14 includes a rotating shaft 141, a rotating motor 142, a rotating sprocket 143, and a rotating chain 144. There are two horizontally arranged rotating shafts 141, which are respectively arranged on both sides of the rotating frame 13 away from the reference port space, and the rotating shafts 141 are rotatably connected to the frame 1. The rotating motor 142 is fixedly connected to the frame 1 and is arranged on one side of the rotating frame 13. There are two rotating sprockets 143. One rotating sprocket 143 is fixedly connected to the drive shaft of the rotating motor 142, and the other rotating sprocket 143 is fixedly connected to the corresponding rotating shaft 141. The rotating chain 144 is sleeved on the two rotating sprockets 143 and meshes with both rotating sprockets 143.

[0048] After the rotating motor 142 is started, it can make the rotating frame 13 rotate through the cooperation of the two rotating sprockets 143 and the rotating chain 144.

[0049] Referring to Figure 3 and Figure 4 , the winding drive assembly 21 includes a winding motor 211, a first bearing 212, a limit disk 213, a fixed chuck 214, a winding cylinder 215, a moving chuck 216, and a second bearing 217. The winding motor 211 and the winding cylinder 215 are respectively arranged 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.

[0050] Referring to 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 limit disk 213. The limit disk 213 is a circular plate-like body, the limit disk 213 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.

[0051] Referring to Figure 4 , the fixed chuck 214 includes a fixing portion and a clamping portion, and the fixing portion and the clamping portion are integrally formed. Both the fixing portion and the clamping portion are circular plate-like bodies, and the diameter of the fixing portion is larger than that of the clamping portion. The fixed chuck 214 is vertically arranged, and the fixing portion is fixedly connected to the limit disk 213.

[0052] Referring to Figure 3 and Figure 4 , the moving chuck 216 has the same structure as the fixed chuck 214. The core 22 is a cylinder with openings at both ends. The clamping portions of the fixed chuck 214 and the moving chuck 216 can both be inserted into the hollow portion of the core 22 to realize the clamping and limiting of the core 22. The driving shaft of the winding cylinder 215 passes through the rotating frame 13, the second bearing 217 is sleeved on the driving shaft of the winding cylinder 215, and the moving chuck 216 is fixedly connected to the outer wall of the second bearing 217.

[0053] During the winding process, the winding motor 211 drives the limit disk 213 to rotate, thereby driving the fixed chuck 214 and the moving chuck 216 to rotate synchronously, ensuring that the core 22 stably winds the drip irrigation tape. At the same time, the first bearing 212 and the second bearing 217 respectively reduce the frictional force of the driving shafts of the winding motor 211 and the winding cylinder 215 during the rotation process, improving the transmission efficiency and service life. When the core 22 needs to be replaced, the winding cylinder 215 expands and contracts, so that the moving chuck 216 moves away from the fixed chuck 214, facilitating the quick disassembly of the fully loaded core 22 and the installation of a new empty core 22, thereby realizing an efficient and continuous winding operation. The whole process has a high degree of automation, greatly improving the production efficiency and operation convenience.

[0054] Referring to Figure 2 and Figure 5 , a horizontal moving component 31 is arranged between the wire arranging device 3 and the frame 1, which is used to drive the wire arranging device 3 to move sequentially along the axis direction of the core 22, so that the drip irrigation tape on the core 22 is wound evenly.

[0055] The horizontal moving component 31 includes a fixed frame 311, a moving motor 312, a moving lead 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 lead screw 313 are rotatably connected to the fixed frame 311, and the length direction of the moving lead screw 313 is parallel to the axis of the core 22. One end of the moving lead 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 lead screw 313 and is threadedly connected to the moving lead screw 313. The horizontal moving frame 314 is in sliding contact with the fixed frame 311. The support plate of the wire arranging device 3 is fixedly connected to the horizontal moving frame 314.

[0056] During the winding process of the drip irrigation tape, the moving motor 312 is started. The moving motor 312 drives the moving lead screw 313 to rotate, and the moving lead screw 313 drives the horizontal moving frame 314 to move, thereby driving the wire arranging device 3 to move, so that the drip irrigation tape is evenly wound in the length direction of the core 22.

[0057] Refer to Figure 5 , the wire arranging device 3 includes two parallel support plates and a plurality of rollers.

[0087] The loading chain 93 is sleeved on the two loading sprockets 92 in the same loading group and meshes with both loading sprockets 92. The driving shaft of the loading motor 91 passes through and is fixedly connected with any one of the loading sprockets 92. There are multiple fixing devices 8, and they are arranged at intervals along the loading chain 93.

[0088] Start the loading motor 91, the loading motor 91 drives the loading sprocket 92 to rotate, and the loading sprocket 92 drives the loading chain 93 to move, which can stably and efficiently transport multiple fixing devices 8 to the loading station 71 in sequence, ensuring that each fixing device 8 can accurately reach the predetermined position and clamp the core 22.

[0093] The principle of use of the present application is as follows: the drip irrigation tape is sequentially wound around the multiple rollers of the cable arranging device 3, then passed through the limit ring on the extension rod, and wound around the core 22 of the winding station 11. When the core 22 of the winding station 11 is wound around the drip irrigation tape, the core 22 needs to be replaced. First, the control system starts the rotating device 14 to drive the rotating frame 13 to flip 180 degrees, so that the positions of the winding station 11 and the preparatory station 12 are interchanged. Then, the cutting device 4 will cut off the drip irrigation tape on the full winding station 11, and the lower winding device 5 will then act to remove the completed winding core 22 from the preparatory station 12. At the same time, the core changing device 6 in the feeding mechanism will take a new empty core 22 at the feeding station 71 and send it to the winding drive assembly 21 newly converted to the preparatory station 12 to ensure continuous operation. The entire process does not require manual intervention, which greatly improves the automation and production efficiency of the equipment. In addition, the addition of the counter 32 on the cable arranging device 3 makes the winding of the drip irrigation tape more accurate and avoids the problem of wasting materials. Through the synergistic effect of multiple fixing devices 8 and the feeding drive device 9, the stability and reliability of the supply of the winding core 22 are guaranteed. The entire system is uniformly managed by the control system, and the various parts operate in coordination, which significantly reduces the failure rate and prolongs the service life of the equipment.

Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
