Technical Field
[0001] This invention relates to the field of nonwoven fabric conveying, and more specifically to a roll-type nonwoven fabric suspension conveying device. Background Technology
[0002] In the nonwoven fabric manufacturing industry, roll-packaged nonwoven fabric is the core storage and circulation form for finished and semi-finished nonwoven fabrics, widely used in many industries such as medical and health, industrial filtration, and home textiles. After being slit and rolled, nonwoven fabrics need to be continuously transported over long distances and across multiple workstations through multiple processes such as packaging, sterilization, warehousing, and outbound delivery. This places extremely high demands on the non-damaging nature and operational stability of the transport process. Currently, the industry's conventional roll-packaged nonwoven fabric transport mostly uses automated guided vehicles (AGVs) or roller conveyors and chain conveyors. AGV transport modes have low transport efficiency and are prone to causing surface contamination and edge damage to the fabric, making them unsuitable for the pace of high-speed continuous production lines. Traditional planar conveying equipment can only achieve horizontal flow along a fixed path, which cannot meet the three-dimensional conveying needs of multi-station modern factories. In addition, rolls of nonwoven fabric are prone to rolling and shifting during the conveying process, requiring the addition of a large number of limiting fixtures. It is difficult to flexibly adapt to the flexible conveying needs of rolls of nonwoven fabric with different diameters and widths. Therefore, suspended conveying has gradually become the mainstream development direction for three-dimensional conveying of rolls of nonwoven fabric.
[0003] Currently, the mainstream suspended conveyor structures are divided into two categories: external clamping type and single-axis insertion type. The external clamping structure directly clamps the outer surface of the nonwoven fabric roll using clamps, which easily causes fabric wrinkles, loosening, and surface scratches. This is especially true for high-grammage and wide-width nonwoven fabric rolls, where controlling the clamping force is extremely difficult, easily leading to problems such as unstable clamping, dropping, or over-clamping and damage to the product. The single-axis insertion type achieves suspension by inserting a roller into the inner hole of the roll. Although it avoids direct contact with the fabric surface, the roll of nonwoven fabric is prone to axial movement and circumferential rotation during conveying, making it impossible to achieve stable radial and circumferential limiting. Furthermore, the loading and unloading alignment and limiting locking of the roll of nonwoven fabric require additional independent lifting and locking mechanisms, making it impossible to achieve a smooth connection between picking and limiting actions.
[0004] In addition, existing roll-type nonwoven fabric overhead conveyor equipment requires independent control of core processes such as loading / unloading alignment and conveying limit switches through different actuators, lacking a coherent action connection logic and collaborative operation mechanism between processes. This independent control mode not only requires configuring independent drive units and control elements for each process, resulting in an overly complex structure of the entire conveyor device and significantly increasing equipment manufacturing and maintenance costs, but also makes it prone to asynchronous action connections between different mechanisms during process transitions, leading to alignment deviations. This not only significantly lengthens the cycle time of single-roll conveying, making it unsuitable for the high-speed continuous operation requirements of nonwoven fabric production lines, but also directly causes roll-type nonwoven fabric to deviate and collide during transfer, seriously affecting the operational stability of the conveyor device and the product delivery qualification rate. Therefore, it is necessary to design a roll-type nonwoven fabric overhead conveyor device. Summary of the Invention
[0005] Therefore, it is necessary to provide a roll-type nonwoven fabric suspension conveying device to address the existing technical problems.
[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:
[0007] A roll-type nonwoven fabric suspension conveying device includes a conveyor chain and a conveyor frame disposed at the lower end of the conveyor chain and driven by the conveyor chain, and further includes:
[0008] A limiting plate is set in the middle of the conveyor frame, and two support rods are symmetrically deflected at the bottom of the conveyor frame. When transporting rolls of nonwoven fabric, the two support rods deflect and form an acute angle with the limiting plate. The rolls of nonwoven fabric are limited by the acute angle under their own weight.
[0009] The two sides of the conveyor frame are symmetrically equipped with suspension mechanisms. The suspension mechanism includes a dual-axis moving mechanism with a fixed end that is fixed to the conveyor frame. The output end of the dual-axis moving mechanism is fixed to a load box. The middle of the load box is elastically connected to a pressure plate. The middle of the pressure plate is equipped with a brake roller for inserting the roll of nonwoven fabric. When the two brake rollers move, they drive the roll of nonwoven fabric to move synchronously.
[0010] A supplementary pressing mechanism for assisting in the positioning of the workpiece is provided on the side of the pressure plate. The supplementary pressing mechanism includes a pressing roller whose axis is parallel to the axis of the brake roller. The pressing roller is pressed against the outside of the nonwoven fabric during the conveying of the roll.
[0011] Furthermore, a spring is provided at the lower end of the limiting plate. The upper end of the spring is fixed to the conveyor frame, and the lower end is slidably connected to two support rods.
[0012] Furthermore, the middle parts of the two support rods are respectively hinged to the lower end of the conveyor frame, and a pen-shaped cylinder is respectively installed above the two support rods. A rocker seat fixed to the conveyor frame is installed in the middle of the pen-shaped cylinder. The rocker seat is hinged to the cylinder wall of the pen-shaped cylinder, and the output end of the pen-shaped cylinder is hinged to the end of the support rod.
[0013] Furthermore, a sliding cylinder is provided on the upper and lower sides of the load box, and a container is provided on the side of the load box near the pressure plate. The pressure plate and the container are slidably connected, and the output ends of the two sliding cylinders are fixedly connected to the upper and lower ends of the container, respectively.
[0014] Furthermore, a spring is provided at the lower end of the pressure plate, with the upper end of the spring fixedly connected to the pressure plate and the lower end fixedly connected to the housing.
[0015] The load box is equipped with a power supply, and a permanent magnet is installed at the top of the pressure plate. Above the permanent magnet is an electromagnet electrically connected to the power supply, and the electromagnet is fixedly connected to the frame.
[0016] Furthermore, a motor is installed in the middle of the load box, and a rocker arm is rotatably connected to the side of the pressure plate near the load box. The rocker arm is connected to the output end of the motor.
[0017] The pressing roller is slidably connected to the end of the rocker arm away from the pressure plate.
[0018] Furthermore, two strip-shaped limiting holes are provided at the end of the rocker arm away from the pressure plate, and a slide is provided at the end of the rocker arm away from the pressure plate. A guide pin is provided in the strip-shaped limiting hole, and the slide is slidably connected to the strip-shaped limiting hole through the guide pin.
[0019] The pressure roller is fixedly connected to the slide block on the side near the middle of the conveyor frame. An electric telescopic rod is provided on one side of the rocker arm, and the output end of the electric telescopic rod is fixedly connected to the slide block.
[0020] Furthermore, the pressing roller is coaxially fixed with a rubber sleeve.
[0021] Furthermore, a horizontally positioned guide plate is fixed to one end of the pressure plate near the load box, and vertically positioned guide rails are fixed to both sides inside the load box. Guide sliders are slidably connected to the guide rails, and the guide sliders are slidably connected to the guide plate.
[0022] The output end of the motor is coaxially fixed to a bushing, and the bushing is coaxially keyed to a main shaft. The rocker arm is fixed to a central shaft at the end near the guide plate, and the central shaft is rotatably connected to the pressure plate.
[0023] A support plate is provided on one side of the two guide rails that are close to each other. The support plate is fixedly connected to the upper end of the two guide sliders. A bearing seat is fixedly connected to the upper end of the support plate. A bevel gear assembly is provided on the upper end of the bearing seat. One end of the bevel gear assembly is fixedly connected to the main shaft along the same axis, and the other end is rotatably connected to a collar. The central shaft is keyed to the collar.
[0024] Furthermore, damping rods are respectively installed above the bearing seats. The output end of the damping rods is fixedly connected to the bearing seats, and the fixed end is fixedly connected to the partition inside the load box.
[0025] The beneficial effects of this invention compared to the prior art are:
[0026] This invention achieves suspended transport by inserting a brake roller into the roll, avoiding direct contact with the nonwoven fabric surface and eliminating quality problems such as fabric wrinkles and contamination at the source. Furthermore, the limiting plate and support rod work together to form an acute angle during transport, relying on the weight of the rolled nonwoven fabric itself to achieve self-locking and limiting, eliminating the need for an additional locking drive mechanism. This simplifies the equipment structure and reduces energy consumption and maintenance costs. Simultaneously, the support rod can quickly deflect to an obtuse angle, providing a smooth rolling guide slope for loading and unloading the rolled nonwoven fabric, eliminating the need for additional alignment and lifting mechanisms and significantly simplifying the loading and unloading process. Moreover, this invention simultaneously achieves three functions—pickup and traction, station transfer, and limiting locking—with a single mechanism, overcoming the limitations of existing equipment that requires multiple independent mechanisms operating in stages. This significantly simplifies the device structure, fundamentally avoiding timing misalignment and alignment deviations during process transitions, eliminating ineffective idle travel, and adapting to the high-speed continuous operation requirements of nonwoven fabric production lines, significantly improving the operational stability and transport efficiency of the conveying device.

[0037] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0038] refer to Figures 1 to 8 A roll-type nonwoven fabric suspension conveying device includes a conveyor chain 1 and a conveyor frame 2 disposed at the lower end of the conveyor chain 1 and driven by the conveyor chain 1, and further includes:
[0039] A limiting plate 3 is provided in the middle of the conveyor frame 2, and two support rods 35 are symmetrically deflected at the bottom of the conveyor frame 2. When transporting the roll of nonwoven fabric, the two support rods 35 deflect and form an acute angle with the limiting plate 3. The roll of nonwoven fabric is limited by the acute angle under its own weight.
[0040] The two sides of the conveyor frame 2 are symmetrically provided with suspension mechanisms 5. The suspension mechanism 5 includes a dual-axis moving mechanism 6 whose fixed end is fixedly connected to the conveyor frame 2. The output end of the dual-axis moving mechanism 6 is fixedly connected to a load box 7. The middle of the load box 7 is elastically connected to a pressure plate 11. The middle of the pressure plate 11 is provided with a brake roller 12 for inserting the roll of nonwoven fabric. When the two brake rollers 12 move, they drive the roll of nonwoven fabric to move synchronously.
[0041] A supplementary pressing mechanism 8 for auxiliary positioning of the workpiece is provided on the side of the pressure plate 11. The supplementary pressing mechanism 8 includes a pressing roller 28 whose axis is parallel to the axis of the brake roller 12. The pressing roller 28 is pressed against the outside of the nonwoven fabric during the conveying of the roll.
[0042] During operation, the conveyor chain 1 drives the conveyor frame 2, which is fixed at the lower end, to move synchronously and stop precisely beside the roll of nonwoven fabric to be conveyed. The symmetrical suspension mechanisms 5 on both sides start synchronously. The dual-axis moving mechanism 6 drives the load box 7 to complete multi-degree-of-freedom linkage displacement. First, the brake roller 12 in the middle of the pressure plate 11 is aligned coaxially with the inner hole of the roll. Then, the brake rollers 12 on both sides are driven to feed synchronously in opposite directions, inserting into the inner hole of the roll from both ends. At this time, the roll of nonwoven fabric is directly suspended on the brake roller 12, which provides stable suspension support and displacement traction for the roll of nonwoven fabric. During traction, the pressure plate 11 adheres to the end faces of both ends of the roll to prevent the roll of nonwoven fabric from slipping off the ends of the brake roller 12. Simultaneously, the double support rods 35 at the bottom of the conveyor frame 2 rotate downwards synchronously, forming an obtuse angle with the middle limiting plate 3, creating a downward-sloping rolling guide slope to prepare for the loading and positioning of the roll of nonwoven fabric.
[0043] After the roll of nonwoven fabric is stably suspended by the brake roller 12, the device enters the synchronous switching process of conveying limit state. The dual-axis moving mechanism 6 drives the roll of nonwoven fabric to complete the lifting and horizontal displacement through the brake roller 12, and moves it precisely to the top of the double support rods 35. At this time, when the dual-axis moving mechanism 6 drives the roll to continue moving towards the limit plate 3, the double support rods 35 deflect upwards in sync, and the angle between the roll and the limit plate 3 gradually narrows from an obtuse angle to an acute angle. Due to the elastic setting of the pressure plate 11, the pressure plate 11 will drive the roll of nonwoven fabric to fall down on its own with the deflection of the limit plate 3. When the roll is smoothly lowered to the upper end of the support rod 35, the support rod 35 just completes the acute angle deflection positioning, and together with the limit plate 3, forms an upward-opening limit slot. The roll of nonwoven fabric is automatically locked in the slot under its own gravity. Without the need for an additional locking mechanism and power input, the circumferential and radial self-locking limit can be completed, which avoids the problem of roll rolling and jumping during the conveying process from the root, and realizes the synchronous completion of roll lowering and limit locking, and smoothly completes the state switch from suspension transport to conveying limit.
[0044] Once the roll has completed its self-weight locking and limiting, the device enters an omnidirectional closed-loop locking and stable conveying process. The auxiliary pressure mechanism 8 beside the pressure plate 11 works synchronously with the limiting and locking mechanism. Simultaneously, as the support rod 35 completes its acute-angle limiting, the auxiliary pressure mechanism 8 drives the clamping roller 28, parallel to the axis of the brake roller 12, to move synchronously, smoothly pressing against the radially outer side of the rolled nonwoven fabric. At this point, the device forms an omnidirectional closed-loop constraint system: the brake roller 12 is inserted into the roll for suspension and positioning; the support rod 35's bottom is supported by its own weight and self-locking; the clamping roller 28 provides radial outward pressure to prevent swaying; and the pressure plate 11's end face provides axial limiting. This completely eliminates the risks of roll movement, jumping, and rolling during long-distance conveying, avoiding quality defects such as loose rolls, wrinkles, and surface contamination of the nonwoven fabric. After conveying to the correct position, each mechanism unlocks synchronously in reverse order, completing automated unloading and achieving a fully closed-loop operation.
[0045] When the roll of nonwoven fabric is limited by the acute angle formed by the limiting plate 3 and the support rod 35, the following features are specifically provided to support the lower part of the roll of nonwoven fabric:
[0046] like Figure 3 As shown, a spring piece 4 is provided at the lower end of the limiting plate 3. The upper end of the spring piece 4 is fixedly connected to the conveyor frame 2, and the lower end is slidably connected to two support rods 35.
[0047] When the support rod 35 deflects, the spring plate 4 can adaptively deform elastically according to the deflection angle of the support rod 35. When the support rod 35 deflects to the conveying limit state with an acute angle, the spring plate 4 can provide auxiliary elastic support force, enhance the load-bearing stability of the support rod 35, and prevent the support rod 35 from deflecting in the opposite direction after being loaded. After the roll of nonwoven fabric is finished feeding, the elastic restoring force of the spring plate 4 can assist the support rod 35 to quickly return to its initial state, and push the roll of nonwoven fabric to roll down during the restoring process. At the same time, the sliding connection between the spring plate 4 and the support rod 35 can prevent the support rod 35 from getting stuck during the deflection process, ensuring the smoothness of the deflection action.
[0048] To achieve the deflection of the two support rods 35°, the following features were specifically designed:
[0049] like Figure 2 As shown, the middle parts of the two support rods 35 are respectively hinged to the lower end of the conveyor frame 2. A pen-shaped cylinder 36 is respectively provided above the two support rods 35. A rocker seat 37 fixed to the conveyor frame 2 is provided in the middle of the pen-shaped cylinder 36. The rocker seat 37 is hinged to the cylinder wall of the pen-shaped cylinder 36. The output end of the pen-shaped cylinder 36 is hinged to the end of the support rod 35.
[0050] When the drive rod 35 needs to deflect to switch angles, the output end of the pen-shaped cylinder 36 extends or retracts, causing the drive rod 35 to deflect around its central hinge point. Simultaneously, the cylinder body of the pen-shaped cylinder 36 can adaptively swing around the hinge point of the rocker seat 37, adapting to the angle changes during the deflection of the drive rod 35 and avoiding motion interference. Through the extension and retraction control of the pen-shaped cylinder 36, the angle between the drive rod 35 and the limiting plate 3 can be precisely adjusted to meet the limiting and loading / unloading requirements of rolls of nonwoven fabric with different diameters.
[0051] To enable the two brake rollers 12 to move closer together and further apart, facilitating insertion and disengagement from the roll of nonwoven fabric, the following features are specifically provided:
[0052] like Figure 4 and Figure 5 As shown, a sliding cylinder 9 is provided on the upper and lower sides of the load box 7, and a container 10 is provided on the side of the load box 7 near the pressure plate 11. The pressure plate 11 and the container 10 are slidably connected, and the output ends of the two sliding cylinders 9 are fixedly connected to the upper and lower ends of the container 10, respectively.
[0053] When it is necessary to drive the two brake rollers 12 to move closer or further apart, the output end of the slide cylinder 9 extends or retracts synchronously, driving the housing 10 to move horizontally. This, in turn, drives the pressure plate 11 and brake rollers 12 to move horizontally in sync, enabling the brake rollers 12 to be fed into the inner hole of the drum in opposite directions or retracted out of the drum. The synchronous drive of the upper and lower slide cylinders 9 ensures uniform force distribution during the movement of the housing 10 and brake rollers 12, preventing skewing and jamming, and ensuring the coaxial alignment accuracy of the brake rollers 12 and the inner hole of the drum.
[0054] To enable the switching between elastic and inelastic connections between the pressure plate 11 and the housing 10, the following features are specifically provided:
[0055] like Figure 4 and Figure 5 As shown, a spring 34 is provided at the lower end of the pressure plate 11. The upper end of the spring 34 is fixedly connected to the pressure plate 11, and the lower end is fixedly connected to the housing 10.
[0056] A power supply is provided in the load box 7, and a permanent magnet 33 is provided at the upper end of the pressure plate 11. An electromagnet 32 electrically connected to the power supply is provided above the permanent magnet 33, and the electromagnet 32 is fixedly connected to the frame 10.
[0057] Under normal conditions, with the power off, the electromagnet 32 is non-magnetic, and the pressure plate 11 is elastically connected to the container 10 via the spring 34. It can adaptively float up and down with the position change of the roll of nonwoven fabric, realizing automatic lowering and flexible adaptation of the roll of nonwoven fabric. When it is necessary to switch to a non-elastic connection state, the power is turned on, the electromagnet 32 is energized and generates magnetism, attracting each other with the permanent magnet 33, rigidly locking the pressure plate 11 and the container 10 into one, eliminating elastic floating, ensuring the positional accuracy of the brake roller 12 when it drives the roll of nonwoven fabric to make spatial displacement, and preventing the roll of nonwoven fabric from shaking or shifting.
[0058] To ensure that when the roll of nonwoven fabric is driven to the upper end of the support rod 35 by the two brake rollers 12, the pressing roller 28 can avoid the roll of nonwoven fabric, the following features are specifically provided:
[0059] like Figure 5 , Figure 6 and Figure 7 As shown, a motor 13 is installed in the middle of the load box 7, and a rocker arm 15 is rotatably connected to the side of the pressure plate 11 near the load box 7. The rocker arm 15 is connected to the output end of the motor 13.
[0060] The pressure roller 28 is slidably connected to the end of the rocker arm 15 away from the pressure plate 11.
[0061] During the loading and unloading process of the roll of nonwoven fabric being driven by the brake roller 12 to the upper end of the support rod 35, the motor 13 starts and drives the rocker arm 15 to deflect away from the middle of the conveyor frame 2 through the transmission structure, thereby driving the clamping roller 28 to swing outward synchronously, providing clearance space for the vertical and horizontal movement of the roll of nonwoven fabric, and avoiding motion interference between the clamping roller 28 and the roll of nonwoven fabric; when the roll of nonwoven fabric completes the limit locking and enters the conveying state, the motor 13 drives the rocker arm 15 to reset in the opposite direction, driving the clamping roller 28 to move to the preset station outside the roll of nonwoven fabric, preparing for subsequent clamping and positioning.
[0062] In order to ensure that the clamping roller 28 can be pressed tightly against the roll of nonwoven fabric, the following features are specifically designed:
[0063] like Figure 5 and Figure 7 As shown, the rocker arm 15 has two strip-shaped limiting holes 26 at the end away from the pressure plate 11, and a slide block 30 is provided at the end of the rocker arm 15 away from the pressure plate 11. A guide pin 31 is provided in the strip-shaped limiting hole 26, and the slide block 30 is slidably connected to the strip-shaped limiting hole 26 through the guide pin 31.
[0064] The pressure roller 28 is fixedly connected to the slide block 30 on the side near the middle of the conveyor frame 2. An electric telescopic rod 27 is provided on one side of the rocker arm 15, and the output end of the electric telescopic rod 27 is fixedly connected to the slide block 30.
[0065] When it is necessary to drive the pressing roller 28 to press against the outer side of the roll of nonwoven fabric, the output end of the electric telescopic rod 27 extends, driving the slide 30 to slide along the strip-shaped limiting hole 26 towards the middle of the conveyor frame 2, thereby driving the pressing roller 28 to move synchronously and press smoothly against the outer surface of the roll of nonwoven fabric. By controlling the extension and retraction of the electric telescopic rod 27, the pressing force of the pressing roller 28 can be precisely adjusted to adapt to rolls of nonwoven fabric with different diameters. The strip-shaped limiting hole 26 and the guide pin 31 can ensure the straightness of the slide 30 during movement, prevent the pressing roller 28 from tilting, and ensure uniform pressing force.
[0066] To prevent the pressure roller 28 from squeezing and damaging the rolled nonwoven fabric, the following features are specifically provided:
[0067] like Figure 7 As shown, the pressing roller 28 is coaxially fixed with a rubber sleeve 29.
[0068] During the process of the clamping roller 28 pressing against the outer side of the roll of nonwoven fabric, the rubber sleeve 29 can directly contact the surface of the nonwoven fabric. Utilizing the flexible material properties of the rubber sleeve 29, the rigid impact during the clamping process is buffered, preventing the clamping roller 28 from squeezing and scratching the surface of the nonwoven fabric. At the same time, the rubber sleeve 29 can increase the friction with the surface of the roll of nonwoven fabric, further restricting the circumferential rotation of the roll of nonwoven fabric, improving the anti-loosening effect, and adapting to the protection needs of nonwoven fabric products with different surface characteristics.
[0069] In order to achieve the transmission connection between the output end of motor 13 and rocker arm 15, the following features are specifically provided:
[0070] like Figure 6 , Figure 7 and Figure 8 As shown, a horizontally arranged guide plate 20 is fixedly connected to one end of the pressure plate 11 near the load box 7. Vertically arranged guide rails 22 are fixedly connected to both sides inside the load box 7. A guide slider 19 is slidably connected to the guide rail 22. The guide slider 19 is slidably connected to the guide plate 20.
[0071] The output end of motor 13 is coaxially fixed to bushing 24, bushing 24 is coaxially keyed to main shaft 14, rocker arm 15 is fixed to one end near guide plate 20 with central shaft 17, central shaft 17 is rotatably connected to pressure plate 11;
[0072] A support plate 21 is provided on one side of the two guide rails 22 that are close to each other. The support plate 21 is fixedly connected to the upper end of the two guide sliders 19. A bearing seat 18 is fixedly connected to the upper end of the support plate 21. A bevel gear group 16 is provided on the upper end of the bearing seat 18. One end of the bevel gear group 16 is fixedly connected to the main shaft 14 along the same axis, and the other end is rotatably connected to a collar 25. The central shaft 17 is keyed to the collar 25.
[0073] When the slide cylinder 9 pushes the container 10 to move so that the brake roller 12 can be inserted into and removed from the roll of nonwoven fabric, the guide plate 20 can slide horizontally along the guide slider 19. When the pressure plate 11 floats elastically up and down along the container 10 under the action of the spring 34, the guide slider 19 can slide vertically along the guide rail 22, thereby providing a two-degree-of-freedom guide for the pressure plate 11 and preventing the pressure plate 11 from tilting.
[0074] Meanwhile, the main shaft 14 forms an axially sliding key connection with the output end of the motor 13 through the bushing 24, and the central shaft 17 forms an axially sliding key connection with the bevel gear group 16 through the collar 25. During the displacement of the pressure plate 11, the motor 13 drives the rocker arm 15 to rotate sequentially through the bushing 24, the main shaft 14, the bevel gear group 16 and the central shaft 17. This ensures that the transmission connection between the output end of the motor 13 and the rocker arm 15 is always uninterrupted, guaranteeing the precise and controllable deflection action of the rocker arm 15, and preventing transmission failure due to the floating of the pressure plate 11.
[0075] To prevent the vertical movement of the guide plate 20 from shifting, the following features are specifically provided:
[0076] like Figure 8 As shown, damping rods 23 are respectively provided above the bearing seat 18. The output end of the damping rod 23 is fixedly connected to the bearing seat 18, and the fixed end is fixedly connected to the partition inside the load box 7.
[0077] As the guide plate 20 moves up and down with the pressure plate 11, the guide slider 19 drives the output end of the damping rod 23 to extend and retract synchronously through the support plate 21 and the bearing seat 18. The damping rod 23 can provide buffer damping force for the up and down movement of the bearing seat 18, thereby buffering and limiting the vertical movement of the guide plate 20 and the pressure plate 11, preventing the pressure plate 11 from shifting during floating, and suppressing the vibration of the pressure plate 11 during conveying, improving the suspension stability of the brake roller 12 and the roll of nonwoven fabric, and ensuring the reliability of axial limiting.
[0078] The detailed working principle of this device is as follows: After the device is started, the conveyor chain 1 drives the conveyor frame 2 fixed at the lower end to move synchronously and stop precisely at the loading station of the roll of nonwoven fabric to be conveyed. At this time, the sliding cylinders 9 of the suspension mechanisms 5 on both sides start synchronously, driving the container frame 10, the pressure plate 11 and the brake roller 12 to move horizontally in opposite directions, so that the brake roller 12 is coaxially aligned with the inner hole of the roll and smoothly inserted into the inner hole. The roll of nonwoven fabric is directly suspended on the brake roller 12. The pressure plate 11 fits against the end faces of both ends of the roll to complete the axial limit and prevent the roll of nonwoven fabric from slipping off the end of the brake roller 12. At this time, the pen-shaped cylinder 36 starts, driving the support rod 35 to deflect downward around the central hinge point, forming an obtuse angle with the limiting plate 3. At the same time, the motor 13 drives the rocker arm 15 to deflect outward, driving the clamping roller 28 to complete the avoidance, providing interference-free space for the transfer of the roll of nonwoven fabric.
[0079] Subsequently, the dual-axis moving mechanism 6 is activated, driving the brake roller 12 and the roll of nonwoven fabric to complete the lifting and horizontal displacement through the load box 7, precisely moving it to directly above the two support rods 35. At this time, the electromagnet 32 is de-energized and demagnetized, and the pressure plate 11 returns to the elastic connection state with the frame 10 through the spring 34. While the dual-axis moving mechanism 6 drives the roll of nonwoven fabric to move towards the limiting plate 3, the pen-shaped cylinder 36 drives the support rod 35 to deflect upward synchronously, and the angle between it and the limiting plate 3 gradually narrows from an obtuse angle to an acute angle. Under the action of the spring 34, the pressure plate 11 drives the roll of nonwoven fabric to fall adaptively and is placed stably on the upper surface of the support rod 35. Under its own gravity, the roll of nonwoven fabric automatically locks into the limiting slot formed by the acute angle, completing the powerless self-locking limit.
[0080] Simultaneously, motor 13 reverses the rocker arm 15 to reset, and electric telescopic rod 27 starts, driving slide block 30 to slide along strip-shaped limiting hole 26 towards the roll of nonwoven fabric. This allows the rubber sleeve 29 on the outside of the pressure roller 28 to smoothly press against the outer surface of the roll of nonwoven fabric, forming an omnidirectional closed loop in conjunction with brake roller 12, support rod 35, and limiting plate 3. Damping rod 23 can suppress the floating of pressure plate 11, and spring sheet 4 provides auxiliary elastic support for support rod 35, improving overall load-bearing stability. Only after all mechanisms have completed locking and positioning does the conveyor chain 1 gain start-up permission, driving the roll of nonwoven fabric to complete long-distance stable conveying.
[0081] After being conveyed to the unloading station, the conveyor chain 1 stops running, the electric telescopic rod 27 drives the clamping roller 28 to reset, the motor 13 drives the rocker arm 15 to deflect outward to complete the avoidance, the pen-shaped cylinder 36 drives the support rod 35 to deflect downward to switch to the obtuse angle state, at the same time the electromagnet 32 is energized to generate magnetism, attracting the permanent magnet 33 to rigidly lock the pressure plate 11 and the container 10, the dual-axis moving mechanism 6 drives the brake roller 12 and the roll of nonwoven fabric to be lifted and moved to the unloading position, the slide cylinder 9 drives the brake roller 12 to retract in the opposite direction and exit the roll, completing the automated unloading. After the unloading is completed, all mechanisms reset synchronously and enter the next conveying cycle.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
