Description

Technical Field

[0001] This application relates to the field of vegetation nets, and more particularly to an unwinding device for a multi-layer vegetation net. Background Technology

[0002] Vegetation nets are laid on slopes, and plants are planted on the nets to protect the slopes and reduce soil erosion. Vegetation nets are beneficial to the production of slope vegetation and have great application value in soil and water conservation in my country. The vegetation net consists of four layers of plastic netting. The staggered distribution of the four layers of plastic netting improves the stability of the plants on the vegetation net.

[0003] Reference Figure 1 Currently, the unwinding device for vegetation netting includes a frame 1, four feeding rollers 2, and a drive unit for unwinding the wound plastic netting on the four feeding rollers 2. The feeding rollers 2 are horizontally arranged, and their length direction is perpendicular to the length direction of the frame 1. The four feeding rollers 2 are distributed along the length direction of the frame 1 and are rotatably connected to the frame 1. The drive unit includes a drive roller 311, a driven roller 312, two sliding blocks 313, a drive motor 71, and two drive cylinders 315. The drive roller 311 is located on the side of the feeding rollers 2 near the discharge end, and its length direction is parallel to the length direction of the feeding rollers 2. The drive roller 311 is rotatably connected to the frame 1. The drive motor 71 is mounted on the frame 1. Two sliding blocks 313 are distributed along the length of the drive roller 311 to drive the drive roller 311 to rotate. The sliding blocks 313 slide vertically to connect to the frame 1. The length of the driven roller 312 is parallel to the length of the drive roller 311. The driven roller 312 is located above the drive roller 311. The two ends of the driven roller 312 are rotatably connected to the two sliding blocks 313. Two drive cylinders 315 correspond one-to-one with the two sliding blocks 313. The drive cylinders 315 are vertically arranged. The cylinder body of the drive cylinder 315 is set on the frame 1. One end of the piston rod of the drive cylinder 315 is set on the sliding block 313. The plastic mesh wound on the feeding roller 2 is conveyed between the drive roller 311 and the driven roller 312.

[0004] The drive cylinder 315 drives the sliding block 313 to move, which brings the driven roller 312 closer to the drive roller 311. The driven roller 312 and the drive roller 311 clamp the four layers of plastic mesh. The drive roller 311 rotates, which drives the four layers of plastic mesh to be fed at the same time. At the same time, the feeding roller 2 is passively unwound.

[0005] Since the inner two layers of the four-layer plastic mesh do not contact the drive roller and the driven roller, and are only conveyed by the friction of the plastic mesh, when the conveying speed is high, the inner two layers of plastic mesh are prone to detach from the outer two layers of plastic mesh, which can easily lead to poor product quality. Therefore, the material can only be unwound at low speed, resulting in low working efficiency. Summary of the Invention

[0006] To improve work efficiency, this application provides an unwinding device for producing vegetation nets.

[0007] This application provides an unwinding device for producing vegetation nets, which adopts the following technical solution:

[0008] A winding device for producing vegetation netting includes a frame, four feeding rollers, a drive assembly for feeding plastic netting, and an integral component for pressing four layers of plastic netting together. The four feeding rollers are distributed along the feeding direction of the plastic netting and are rotatably connected to the frame. The drive assembly is located on the side of the feeding rollers facing the feeding direction. The drive assembly includes four drive groups and a mounting frame. The mounting frame is disposed on the frame. The four drive groups correspond one-to-one with the four feeding rollers. Each drive group includes a drive roller, a driven roller, a transmission component, and a drive cylinder. The length direction of the drive roller is parallel to the length direction of the feeding rollers. The drive roller is rotatably connected to the mounting frame. The length direction of the driven roller is parallel to the length direction of the drive roller. The driven roller is slidably connected to the mounting frame. The drive cylinder drives the driven roller to move closer to the drive roller. The drive group is used to drive the four drive rollers to rotate simultaneously. The integral component is located on the side of the drive assembly away from the feeding rollers.

[0009] By adopting the above technical solution, the driven cylinder drives the driven roller to move, pressing the plastic mesh located between the driven roller and the drive roller together. The transmission component drives four drive rollers to rotate simultaneously, and the four drive groups drive four layers of plastic mesh to feed simultaneously. Then, the four layers of plastic mesh are integrated and transported by the integrating component. Because the plastic mesh is transported separately, the reliability of plastic mesh transport is increased. Even at a high transport speed, the four plastic meshes can maintain their relative positions during transport. By increasing the plastic mesh transport speed, production efficiency is improved.

[0010] Optionally, the mounting frame includes two gantry frames, four mounting seats, three connecting rods, and an adjusting component for adjusting the distance between the two gantry frames. The two gantry frames are distributed along the feeding direction of the plastic mesh and are slidably connected to the machine frame along the feeding direction of the plastic mesh. The four mounting seats are evenly distributed on the two gantry frames and are staggered along the vertical direction. The four drive groups correspond one-to-one with the four mounting seats and are set on the mounting seats. One of the mounting seats is set on the corresponding gantry frame, and the remaining three mounting seats are slidably connected to the gantry frames along the vertical direction. The three connecting rods are alternately arranged with the four mounting seats, and the two ends of the three connecting rods are respectively connected to adjacent mounting seats.

[0011] By adopting the above technical solution, problems such as burrs, flash, and inadequate trimming of the flow channel may occur during the production of plastic mesh. During the unwinding process, the drive roller and driven roller may get stuck due to the plastic mesh. Since four layers of plastic mesh are transported simultaneously, it is difficult for workers to observe the condition of the inner two layers when stuck. It is necessary to stop the machine, disassemble all four layers of plastic mesh at the same time, remove the excess parts, and then reinstall the plastic mesh on the equipment, resulting in low work efficiency. Workers can use the adjustment component to bring the two gantry frames closer together. During the process of bringing the two gantry frames closer together, a mounting base is set on the gantry frame. Under the guidance of three connecting rods, the vertical spacing of the four mounting bases gradually increases, and the spacing of the drive groups on the mounting bases also gradually increases. This makes it easier for workers to observe the condition of each plastic mesh and to troubleshoot the stuck problem.

[0012] Optionally, the adjusting component includes a bidirectional screw and a turntable. The length direction of the bidirectional screw is parallel to the moving direction of the gantry. The two gantry frames are respectively threaded to opposite threaded sections of the bidirectional screw. The bidirectional screw is rotatably connected to the frame. One end of the turntable is mounted on the bidirectional screw.

[0013] By adopting the above technical solution, the staff can rotate the turntable, which drives the bidirectional screw to rotate. The rotation of the bidirectional screw causes the two gantry frames to move closer or further apart. Since the machine is often stopped during maintenance and troubleshooting, it is more reasonable to adjust the gantry frames manually, which also makes it easier for the staff to control and adjust the position of the drive unit.

[0014] Optionally, the bidirectional screw is provided with a limiting component to restrict the rotation of the bidirectional screw. The limiting component includes a limiting spring, a limiting tube, and two limiting arc plates. The limiting tube is sleeved on the bidirectional screw and is disposed on the frame. The axis of the limiting arc plate is parallel to the axis of the limiting tube. The two limiting arc plates are circumferentially distributed along the axis of the turntable. One end of the limiting arc plate is rotatably connected to the turntable. The limiting spring is used to press the inner sidewall of the limiting arc plate against the outer sidewall of the limiting tube.

[0015] By adopting the above technical solution, since the bidirectional screw is only used during maintenance, it is not needed during normal operation. However, the equipment will vibrate during operation, causing the bidirectional screw to rotate. The limiting component directly reduces the rotation of the bidirectional screw relative to the frame. By using the elastic force of the limiting spring, the two arc-shaped limiting plates are pressed against the outer wall of the limiting tube. When the operator needs to rotate the bidirectional screw, the two arc-shaped limiting plates can overcome the elastic force of the limiting spring and move away from the limiting tube. Then the operator can rotate the turntable to drive the bidirectional screw to rotate. The limiting component improves the reliability of the adjusting component.

[0016] Optionally, the limiting assembly further includes a detachment component that moves the two limiting arc-shaped plates away from the limiting tube. The detachment component includes a gripping rod, a through tube, two abutting posts, and several extrusion posts. The through tube is located between the two limiting arc-shaped plates, and its length direction is parallel to the tangential direction of the limiting sleeve. The two abutting posts are slidably connected to both ends of the through tube and abut against the ends of the limiting arc-shaped plates away from their rotation axis. The length of the gripping rod is parallel to the length direction of the bidirectional screw, and the gripping rod is eccentrically positioned. The gripping rod is rotatably connected to the screw, and a cavity is formed inside the gripping rod, which communicates with the through tube. The length direction of the extrusion posts is parallel to the radial direction of the gripping rod, and the extrusion posts are slidably connected to the gripping rod and penetrate into the cavity.

[0017] By adopting the above technical solution, when the operator needs to rotate the bidirectional screw to move the two gantry frames, the operator grips the holding rod and moves the extrusion column. The extrusion column moves into the cavity under the operator's grip. Since the cavity is sealed and connected to the through pipe, the abutment columns at both ends of the through pipe move away from the through pipe to maintain stable air pressure in the cavity and through pipe. The abutment columns abut against the limiting arc plate, moving the two limiting arc plates away from the abutment pipe. Then, the operator rotates the holding rod, which drives the turntable to rotate. The turntable drives the bidirectional screw to rotate, and the bidirectional screw can adjust the distance between the two gantry frame supports. The release component combines the limiting component with the turntable component. During the operator's rotation of the holding rod, the limiting arc plate can be released from the limiting pipe. When the operator does not hold the holding rod, the limiting arc plate can abut against the limiting pipe, improving the convenience of the limiting component.

[0018] Optionally, the transmission components include a drive motor, four first bevel gears, four second bevel gears, two rotating rods, two worm gears, and two worm sleeves. The drive motor is mounted on the frame, and the length direction of the output shaft of the drive motor is parallel to the sliding direction of the gantry frame. The two rotating rods correspond one-to-one with the two gantry frames, and one end of each rotating rod is rotatably connected to the gantry frame. The length direction of each rotating rod is parallel to the sliding direction of the mounting base. The two worm gears correspond one-to-one with the two rotating rods, and the worm gears are coaxially arranged with the rotating rods and mounted on the rotating rods. The worm sleeves are slidably connected to the output shaft of the drive motor. The two worms correspond one-to-one with the two worm gears, and the worms mesh with the worm gears. The four first bevel gears correspond one-to-one with the four mounting bases, and the first bevel gears are mounted at one end of the drive roller. The four second bevel gears correspond one-to-one with the four first bevel gears, and each of the four second bevel gears is coaxially arranged with its corresponding rotating rod. The second bevel gears are slidably connected to the rotating rod.

[0019] By adopting the above technical solution, the four drive rollers need to rotate simultaneously, driving the four layers of plastic mesh to move simultaneously. The operator can start the drive motor, which drives the output shaft of the motor to drive the two worm gear sleeves to rotate simultaneously. The two worm gear sleeves drive the two worm wheels to rotate, the two worm wheels drive the two rotating rods to rotate, the two rotating rods drive the four second bevel gears to rotate, the four second bevel gears drive the four first bevel gears to rotate, and the four first bevel gears drive the four drive rollers to rotate. Since the distance between the two gantry frames will change, the worm gear sleeves slide on the output shaft of the drive motor, and the worm gear sleeves and worm wheels always remain in a meshed state. This reduces the possibility of the worm gear sleeves and worm wheels failing to mesh due to misalignment during the gantry frame recovery process. Since the four mounting seats will move with the gantry frame, the second bevel gears slide on the rotating rods, ensuring that the first bevel gears and second bevel gears always remain in a meshed state, improving the reliability of the transmission components driving the drive shaft to rotate.

[0020] Optionally, the frame is further provided with a straightening assembly, which includes two straightening plates, a rotating gear, two sliding racks, and a pusher for reciprocating movement of the straightening plates. The two straightening plates are respectively located on both sides of the plastic mesh along the width direction. The straightening plates move along the width direction of the plastic mesh. The rotating gear is located between the two straightening plates. The two sliding racks correspond one-to-one with the two straightening plates. The length direction of the sliding racks is parallel to the sliding direction of the straightening plates. The two sliding racks are respectively located on both sides of the rotating gear, and the sliding racks mesh with the rotating gear.

[0021] By adopting the above technical solution, the straightening component is used to align the long side of the plastic mesh. The pusher drives one of the straightening plates to move along the width direction of the plastic mesh. The straightening plate drives the corresponding sliding rack to move. The sliding rack drives the rotating gear to rotate. The rotating gear drives the two sliding racks to move relative to each other. The two sliding racks make the two straightening plates move closer or further apart and abut against the long side of the plastic mesh to align the four layers of plastic mesh.

[0022] Optionally, the pushing component includes a pushing disk, a first pushing rod, a second pushing rod, and a bidirectional threaded sleeve. The pushing disk is disposed on one end of the output shaft of the drive motor. The length direction of the first pushing rod is perpendicular to the output shaft of the drive motor. One end of the first pushing rod is rotatably connected to the pushing disk, and the rotation axis of the first pushing rod is eccentrically disposed on the pushing disk. One end of the second pushing rod is rotatably connected to the straightening plate. The length direction of the second pushing rod is parallel to the length direction of the first pushing rod. The length direction of the bidirectional threaded sleeve is parallel to the length direction of the first pushing rod. The bidirectional threaded sleeve is located between the first pushing rod and the second pushing rod. The first pushing rod and the second pushing rod are threadedly connected to the opposite threaded sections of the bidirectional threaded sleeve.

[0023] By adopting the above technical solution, the motor drives the four drive rollers to rotate, which in turn drives the push disk to rotate. The push disk drives the first push rod to move, which in turn drives the bidirectional threaded sleeve to move. The bidirectional threaded sleeve drives the second push rod to move, which in turn drives the straightening plate to move. Through the meshing of two sliding racks and rotating gears, the two straightening plates move closer to each other or further away. Driven by the motor, the two straightening plates reciprocate. When the two straightening plates move closer to each other, the four layers of plastic mesh are aligned. Depending on the width of the plastic mesh, the operator can change the distance between the two straightening plates by rotating the bidirectional threaded sleeve to change the distance between the first and second push rods.

[0024] Optionally, the integrated component includes an integrated roller, a pressing roller, and an integrated cylinder. The length direction of the integrated roller is parallel to the length direction of the drive roller, and the length direction of the pressing roller is parallel to the length direction of the integrated roller. The pressing roller is slidably connected to the frame in a direction close to or away from the integrated roller, and the integrated cylinder is used to drive the pressing roller to move.

[0025] By adopting the above technical solution, the four layers of plastic mesh are inserted between the integrating roller and the clamping roller. The operator drives the integrating cylinder, which drives the clamping roller to move towards the integrating roller. The clamping roller and the integrating roller integrate the four layers of plastic mesh and abut against each other, which facilitates the operation of the four layers of plastic mesh by subsequent equipment. The integrated component has a simple structure and is easy for operators to operate.

[0026] Optionally, the drive roller is provided with several anti-slip grooves to improve friction with the plastic mesh.

[0027] By adopting the above technical solution, the anti-slip groove increases the friction between the plastic mesh and the drive roller, reduces the relative movement between the drive roller and the plastic mesh during high-speed rotation, and improves the reliability of the drive roller in moving the plastic mesh.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. Four drive units are used to simultaneously feed four plastic meshes;

[0030] 2. The adjusting component is used to adjust the distance between the two gantry supports, making it convenient for staff to stop the machine and inspect each drive unit;

[0031] 3. The transmission components ensure that the motor can always drive the four drive rollers to rotate.

[0032] 4. The straightening component enables the alignment and straightening of the long sides of the four-layer plastic mesh. Attached Figure Description

The length direction of the integrated roller 41 is parallel to the length direction of the drive roller 311. The integrated roller 41 is located between the two integrated rods 45, and its two ends are rotatably connected to the integrated rods. On 45, two integrated blocks 43 correspond one-to-one with two integrated rods 45. The integrated blocks 43 slide vertically and are connected to the integrated rods 45. The length direction of the abutting roller 42 is parallel to the length direction of the integrated roller 41. The abutting roller 42 is located between the two integrated blocks 43 and is rotatably connected to the integrated blocks 43. Two integrated cylinders 44 correspond one-to-one with the two integrated rods 45. The integrated cylinders 44 are vertically set, and the cylinder body of the integrated cylinder 44 is fixedly set on the upper end face of the integrated rod 45. The piston rod of the integrated cylinder 44 is fixedly connected to the integrated block 43.

[0050] The implementation principle of the unwinding device for producing vegetation netting according to an embodiment of this application is as follows: The operator places the feeding roller 2, which is wound with plastic netting, on the frame 1. Then, the plastic netting is passed sequentially through the corresponding drive assembly 31. After the plastic netting passes between the drive roller 311 and the driven roller 312, the operator drives the drive cylinder 315 to bring the driven roller 312 closer to the drive roller 311, abutting the plastic netting against the drive roller 311. Then, four layers of plastic netting are passed sequentially through the integrating component 4. The four layers of plastic netting are located between the integrating roller 41 and the abutting roller 42. The operator activates the integrating cylinder 44, which, driven by the integrating block 43, moves the abutting roller towards the integrating roller 41, pressing and abutting the four layers of plastic netting together. The plastic netting is then fed to subsequent equipment. After the plastic netting is fed, the operator can start the drive motor to drive the plastic netting... The net is unwound, which drives the motor to rotate two worm gear sleeves 76. The worm gear sleeves 76 drive the rotating rod 74 to rotate, the rotating rod 74 drives four second bevel gears 73 to rotate, the second bevel gears 73 drive the first bevel gear 72 to rotate, the first bevel gear 72 drives four drive rollers 311 to rotate, and the drive rollers 311 move the plastic net toward the integrated part 4. During this process, the motor drives the push disk 541 to rotate, the push disk 541 drives the first push rod 542 to move, the first push rod 542 drives the second push rod 543 to move through the bidirectional threaded sleeve 544, and the second push rod 543 drives the straightening plate 51 to move. Through the cooperation of the two sliding racks 53 and the rotating gear 52, the two straightening plates 51 move closer or further apart, and the reciprocating motion of the two straightening plates 51 adjusts the length of the plastic net.

[0051] When the equipment jams or needs maintenance, the operator can first shut down the equipment, then hold the gripping rod 641 and press the squeezing column 644 into the cavity 645. In order to maintain balance, the atmospheric pressure in the cavity 645 causes the two abutting columns 643 to move away from the through pipe 642, and drives the limiting arc plate 63 to rotate. The limiting arc plate 63 overcomes the elastic force of the limiting spring 61 and moves away from the limiting pipe 62, reducing the friction of the operator rotating the turntable 326. When the operator rotates the turntable 326, the two gantry frames 321 move closer to each other, and the connecting rod 323 drives the mounting base 322 to move. The longitudinal distance between the four mounting bases 322 gradually increases, and the distance between the four layers of plastic mesh increases, expanding the operator's field of vision, making it easier for the operator to check the internal condition and quickly troubleshoot jamming problems.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
