Description

Technical Field

[0001] This utility model belongs to the technical field of nonwoven fabric forming equipment, and in particular relates to a convenient shaft-changing nonwoven fabric winding mechanism. Background Technology

[0002] In current nonwoven fabric production processes, winding devices generally employ a fixed structural design, primarily consisting of a frame, drive unit, and winding rollers. The winding rollers are typically horizontally mounted on support seats on both sides of the frame via bearings or locking mechanisms, and are driven by a motor to rotate and wind the nonwoven fabric. Once winding is complete, the fully loaded roll (weighing up to several hundred kilograms) requires unloading using external lifting equipment—typically, a gantry crane or electric hoist hook is used to hang both ends of the roll, lifting it into the air before transporting it to a transfer vehicle or storage area. While this structure can perform basic winding functions, the unloading process is highly dependent on additional lifting equipment, and the roll and frame are often rigidly connected, lacking an integrated unloading mechanism.

[0003] The above methods have significant operational bottlenecks: lifting equipment such as gantry cranes need to be installed and positioned independently, occupying production line space and requiring cumbersome preparation processes; during hoisting, manual hooking, aerial movement, and precise positioning are required, which is time-consuming and carries the risk of collisions due to swaying. In addition, frequent hoisting can easily cause deformation or surface damage to the reel, affecting subsequent reusability, while also interrupting continuous production. Overall efficiency and safety cannot meet the needs of modern, high-efficiency production lines. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient nonwoven fabric winding mechanism with a changeable shaft, which aims to solve the technical problem that the gantry crane and other lifting equipment used in the existing nonwoven fabric winding device need to be installed and adjusted independently, occupying production line space and having a complicated preparation process, thus affecting the production efficiency of nonwoven fabric.

[0005] To achieve the above objectives, this utility model provides a convenient nonwoven fabric winding mechanism with a changing shaft, comprising a fixed frame, a rotating frame, a drive source, and a winding shaft; the rotating frame is rotatably connected to the top of the fixed frame; the drive source is driven and connected to the rotating frame and is used to drive the rotating frame to rotate stepwise; the winding shaft is detachably connected to the rotating frame and is used to wind and form nonwoven fabric; wherein, there are two sets of rotating frames, and the two ends of the winding shaft are rotatably connected to the corresponding rotating frames, and the rotating frames are provided with at least two sets of spaced grooves along their rotation path, all of which are aligned in pairs; there are at least two sets of winding shafts, and all of which are rotatably connected to any two sets of aligned grooves.

[0006] Optionally, the rotating frame is arranged in a disc-shaped structure, and the slide groove is formed at the circumferential edge of the rotating frame, the slide groove passing through the circumferential edge of the rotating frame.

[0007] Optionally, the rotation angle of the rotating frame in a single rotation is greater than 90°, and the included angle between the length directions of any two adjacent sets of the sliding grooves is greater than 90°.

[0008] Optionally, the path along the length of all the slides passes through the rotation center of the rotating frame.

[0009] Optionally, the drive source includes a swing arm, a drive arm, and a drive component. One end of the swing arm is fixedly disposed at the rotation center of the rotating frame, and the other end of the swing arm extends in a straight line away from the rotation center of the rotating frame. The swing arm is provided with a guide groove along its length direction. One end of the drive arm is slidably connected to the guide groove, and the output end of the drive component is drivenly connected to the end of the drive arm away from the guide groove.

[0010] Optionally, the driving component is a lifting cylinder.

[0011] Optionally, the output end of the driving component moves in a vertical direction, and the path of the guide groove as the swing arm rotates is always designed to intersect with the path of the output end of the driving component.

[0012] Optionally, the rotating frame is provided with a locking assembly for a useful limiting reel within the slide groove.

[0013] Optionally, the locking assembly includes a locking ring and a latch. One end of the locking ring is rotatably connected to the rotating frame and located on one side of the groove opening of the slide. The other end of the locking ring is provided with a slot. The latch is located on the side of the groove opening away from the locking ring. The locking tongue of the latch can engage with the slot. When the end of the locking ring near the slot can rotate and abut against the rotating seat, the slot is aligned with the locking tongue.

[0014] Optionally, the locking ring is adapted to the shape of the reel, and a buffer layer is provided on the end face of the locking ring facing the groove.

[0015] The above-mentioned one or more technical solutions of the convenient nonwoven fabric winding mechanism for changing shafts provided in this utility model embodiment have at least one of the following technical effects: By controlling two sets of rotating frames to rotate synchronously by a drive source, multiple sets of rolls are moved in an orderly manner along a circular path. When the fully loaded roll rotates with the rotating frame to the preset unloading station, the roll automatically slides down along the aligned groove under the action of gravity to complete the unloading. At the same time, the unloaded roll rotates synchronously to the winding station to take over the operation, which completely replaces the manual hooking, lifting and translation operation of the traditional gantry crane. It not only eliminates the occupation of equipment installation space and the risk of collision, but also realizes the continuous automated operation of winding and unloading, and solves the problems of production line interruption, low efficiency and roll damage caused by fixed structure relying on external hoisting.

[0026] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-3 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0027] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of this utility model, such as Figures 1-3As shown, a convenient nonwoven fabric winding mechanism with a changing shaft is provided, including a fixed frame 100, a rotating frame 200, a drive source 300, and a roll 400; the rotating frame 200 is rotatably connected to the top of the fixed frame 100; the drive source 300 is drivenly connected to the rotating frame 200 and is used to drive the rotating frame 200 to rotate stepwise; the roll 400 is detachably connected to the rotating frame 200 and is used to wind and form nonwoven fabric; wherein, there are two sets of rotating frames 200, and the two ends of the roll 400 are rotatably connected to the corresponding rotating frame 200, and the rotating frame 200 is provided with at least two sets of spaced grooves 500 along its rotation path, and all the grooves 500 are aligned in pairs; there are at least two sets of rolls 400, and all the rolls 400 are rotatably connected to two arbitrarily aligned sets of grooves 500.

[0031] The drive source 300 controls the two sets of rotating frames 200 to rotate synchronously, driving multiple sets of reels 400 to move in an orderly manner along a circular path. When the fully loaded reel 400 rotates with the rotating frame 200 to the preset unloading station, the reel 400 automatically slides down along the aligned slide groove 500 under the action of gravity to complete the unloading. At the same time, the unloaded reel 400 rotates synchronously to the winding station to take over the operation, completely replacing the manual hooking, lifting and translation operations of the traditional gantry crane. This not only eliminates the occupation of equipment installation space and the risk of collision, but also realizes the continuous automated operation of winding and unloading, solving the problems of production line interruption, low efficiency and damage to reel 400 caused by the reliance on external hoisting for fixed structures.

[0032] like Figures 1-3 As shown, in another embodiment of this utility model, the rotating frame 200 is arranged in a disc shape, and the slide groove 500 is formed at the circumferential edge of the rotating frame 200, penetrating the circumferential edge of the rotating frame 200. When the disc-shaped rotating frame 200 rotates, the slide groove 500 located at its circumferential edge rotates accordingly, and both ends of the reel 400 are placed in the corresponding slide groove 500. When the fully loaded reel 400 rotates to a specific angle, the reel 400 slides directly out from the opening of the penetrating slide groove 500 under the action of gravity. The disc structure is compact and rotates smoothly. The design of the slide groove 500 located at the circumferential edge and penetrating the entire reel allows the reel 400 to slide down along the slide groove 500 without obstruction when it reaches the unloading position, eliminating the lifting action and overhead operating space required by traditional hoisting, and effectively solving the problems of large space occupation and complicated operation of hoisting equipment.

[0033] like Figures 1-3As shown, in another embodiment of this utility model, the rotating frame 200 rotates at a single angle greater than 90°, and the included angle between any two adjacent sets of slides 500 along their length is greater than 90°. The drive source 300 drives the rotating frame 200 to rotate more than 90 degrees each time, ensuring that the angle between adjacent workstations (such as the winding workstation and the unloading workstation) is sufficiently large. Adjacent slides 500 also maintain an included angle greater than 90 degrees. This ensures sufficient spacing between adjacent reels 400, preventing interference or collisions during rotation or unloading, guaranteeing the smooth flow of the reels 400 along their gravity-fed path, avoiding the collision risks that may result from the reels 400 swinging in the air during traditional hoisting processes, and improving operational safety. Simultaneously, it ensures that when the slide 500 containing the unloaded reel 400 moves to its highest position for winding, the slide 500 containing the fully loaded reel 400 is tilted downwards, facilitating the movement of the fully loaded reel 400 under load to the opening of the slide 500 for convenient unloading.

[0034] like Figures 1-3 As shown, in another embodiment of this invention, the longitudinal path of all the slides 500 passes through the rotation center of the rotating frame 200. The longitudinal extension line of each slide 500 passes through the center point of the rotating frame 200. This design ensures that when the reel 400 moves within the slide 500, its trajectory is a straight line along the radial direction of the rotating frame 200. When the reel 400 slides down the slide 500 under gravity, its path is a straight line movement in the preset unloading direction, avoiding jamming or deviation, ensuring a smooth and reliable unloading process, and solving the problem of damage to the reel 400 due to swaying during traditional hoisting.

[0035] like Figures 1-3 As shown, in another embodiment of this utility model, the drive source 300 includes a swing arm 310, a drive arm 320, and a drive member 330. One end of the swing arm 310 is fixedly disposed at the rotation center of the rotating frame 200, and the other end of the swing arm 310 extends linearly away from the rotation center of the rotating frame 200. The swing arm 310 is provided with a guide groove 340 along its length direction. One end of the drive arm 320 is slidably connected to the guide groove 340. The output end of the drive member 330 is drivenly connected to the end of the drive arm 320 away from the guide groove 340. The drive member 330 pushes or pulls the drive arm 320 to make linear motion, and one end of the drive arm 320 slides in the guide groove 340 of the swing arm 310, forcing the swing arm 310 to rotate with its fixed end (rotation center) as the fulcrum, thereby driving the entire rotating frame 200 to rotate stepwise. This drive mechanism efficiently converts the linear motion of the drive component 330 into the precise stepping rotation of the rotating frame 200. It has a simple and reliable structure and direct action. Compared with complex gear or chain transmissions, it is easier to maintain and has lower costs, solving the problems of failure and maintenance that may arise from the reliance on complex transmission structures in traditional equipment.

[0036] like Figures 1-3 As shown, in another embodiment of this utility model, the driving component 330 is a lifting cylinder. The piston rod of the lifting cylinder performs a vertical extension and retraction movement, serving as the power source for the driving arm 320. Using a lifting cylinder as the power source offers advantages such as compact structure, fast response, sufficient power, and easy control of stroke and speed. It is particularly suitable for driving the stepping motion of the rotating frame 200, ensuring the accuracy and efficiency of workstation switching, and solving the potential response delay or control complexity issues that may exist when a motor is used in conjunction with a reduction gear mechanism.

[0037] like Figures 1-3 As shown, in another embodiment of this utility model, the output end of the driving member 330 moves vertically, and the path of the guide groove 340 as the swing arm 310 rotates is always intersected with the path of the output end of the driving member 330. The cylinder piston rod moves vertically, pushing the driving arm 320. The driving arm 320 slides within the guide groove 340 of the swing arm 310. Since the trajectory of the guide groove 340 as the swing arm 310 rotates intersects with the vertical trajectory of the piston rod, the driving arm 320 is forced to slide within the guide groove 340 while effectively converting the vertical force into a tangential force that drives the swing arm 310 to rotate. The design of the guide groove 340, where the vertical cylinder and the rotation trajectory intersect, cleverly converts linear driving force into rotational torque. The structure is simple and efficient, with a small space occupation, making it particularly suitable for deployment in environments with limited production line space. It solves the shortcomings of traditional rotary drive devices, which may be bulky and inconvenient to install.

[0038] like Figures 1-3 As shown, in another embodiment of this utility model, a locking assembly 600 is provided on the rotating frame 200 to limit the winding shaft 400 within the slide groove 500. During the winding operation, the locking assembly 600 locks the winding shaft 400 in a designated working position within the slide groove 500, preventing it from sliding accidentally. The locking assembly 600 ensures the stability of the winding shaft 400 during high-speed rotation and winding, preventing it from shifting or coming out of the slide groove 500 due to vibration or centrifugal force, thus ensuring the stability and safety of the winding process and solving the problem of uneven winding or equipment failure that may be caused by the winding shaft 400 not being securely fixed.

[0039] like Figures 1-3As shown, in another embodiment of this utility model, the locking assembly 600 includes a locking ring 610 and a latch 620. One end of the locking ring 610 is rotatably connected to the rotating frame 200 and located on one side of the groove opening of the slide 500. The other end of the locking ring 610 is provided with a slot. The latch 620 is located on the side of the groove opening of the slide 500 away from the locking ring 610. The latch tongue of the latch 620 can engage with the slot (not shown). When the end of the locking ring 610 near the slot can rotate and abut against the spool 400, the slot and the latch tongue are aligned. When locking is required, the locking ring 610 is rotated to encircle the spool 400 and press it into the slide 500. At the same time, the slot at the end of the locking ring 610 aligns with and engages with the latch tongue of the latch 620 fixed on the other side of the slide 500, achieving quick locking. To unlock, simply open the latch 620 and rotate the locking ring 610 to disengage it from the reel 400 and the groove 500. The cooperation between the locking ring 610 and the latch 620 enables quick locking and releasing of the reel 400 within the groove 500. This operation is simple and reliable, requires no additional tools, significantly shortens the preparation time for reel replacement, and solves the problems of time-consuming and labor-intensive traditional bolt fixing or complex fixture installation and removal, which affect continuous production. The locking ring 610's encircling position around the reel 400 increases the contact area, resulting in a more secure fixation.

[0040] like Figures 1-3 As shown, in another embodiment of this utility model, the locking ring 610 is shaped to match the reel 400, and a buffer layer 700 is provided on the end face of the locking ring 610 facing the slide groove 500. The inner contour of the locking ring 610 matches the outer surface of the reel 400, and can fit against the surface of the reel 400 when locked. The surface of the locking ring 610 that contacts the reel 400 or the slide groove 500 is covered with a buffer material (such as rubber or polyurethane). The shape-matched locking ring 610 provides a more uniform clamping force and improves locking reliability. The buffer layer 700 effectively reduces the rigid impact and indentation of the locking ring 610 on the surface of the reel 400, protects the surface of the reel 400 from scratches or deformation, extends the service life of the reel 400, solves the problem that traditional rigid clamps or hooks easily cause damage to the surface of the reel 400, and ensures the reusability of the reel 400.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
