Description

Technical Field

[0001] The utility model relates to the technical field of elastic felt processing, and specifically relates to an automatic winding mechanism for elastic felt production. Background Technique

[0002] An elastic felt is a felt-like material with good elasticity and toughness, usually made of polymer elastic materials or fiber composites. Due to its soft texture, good resilience, wear resistance and other characteristics, it is widely used in fields such as sound insulation, shock absorption, sealing, and warmth preservation, such as the sound insulation layer of industrial equipment, the shock absorption pad of automobile interiors, and the warmth preservation filling of household items. During the production process, after the elastic felt undergoes processes such as forming and cutting, it needs to be wound into a roll through a winding mechanism for subsequent storage, transportation and processing.

[0003] The existing elastic felt winding devices have the following inconveniences in actual use. Traditional winding rollers mostly adopt bolt fixation or integral axle seat installation methods. When disassembling, it is necessary to individually turn the bolts or disassemble the axle seat, which is cumbersome and time-consuming. Especially in scenarios where the winding roller needs to be frequently replaced after the elastic felt winding is completed, it seriously affects the production efficiency. Therefore, an automatic winding mechanism for elastic felt production needs to be developed. Content of the Utility Model

[0030] Please see Figures 1-5 The diagram shows a structural schematic of an embodiment of the automatic winding mechanism for producing elastic felt according to this utility model. Please refer to [link / reference]. Figures 1-5 This section provides a detailed introduction to the automatic winding mechanism used in the production of elastic felt.

[0031] Example 1

[0032] This solution discloses an automatic winding mechanism for producing elastic felt, mainly including a frame 100, a winding roller 200, and a mounting and locking assembly 300. The frame 100 is U-shaped, with a connecting sleeve 101 rotatably mounted on one side via a bearing. The connecting sleeve 101 is perpendicular to the side wall of the frame 100, and a spline groove 102 is recessed at the end of the connecting sleeve 101 located inside the frame 100. One end of the winding roller 200 is fixed with a spline rod 201 adapted to be inserted into the spline groove 102, and the other end is fixed with a mounting rod 202. The mounting and locking assembly 300 is installed on the machine... On the other side of the frame 100 away from the spline slot hole 102, there is a semi-circular mounting groove 301 opened on the upper edge of the side wall of the frame 100, and a semi-circular locking frame 303 rotatably set on the top of the mounting groove 301 via a rotating shaft 302 (which forms a circular hole with the mounting groove 301 after being pressed down and closed). The locking frame 303 has a locking hole 304 on its outer side away from the rotating shaft 302. A bracket 305 is fixed on the top of the frame 100. A sliding rod 306 slides through the side wall of the bracket 305. A locking insert 307 for inserting / removing the locking hole 304 is fixed at one end of the sliding rod 306.

[0033] Solution Analysis: From the perspective of mechanical structure and transmission principle, the "U"-shaped design of the frame 100 provides a stable mounting frame for the take-up roller 200, and the symmetrical layout of the two side walls ensures the force balance of the take-up roller 200. The connecting sleeve 101 is connected to the frame 100 through bearings, realizing free rotation without radial displacement, providing basic support for the rotation of the take-up roller 200. The cooperation between the spline rod 201 and the spline slot 102 is the core transmission structure. The spline connection transmits torque through multi-tooth contact. Compared with the single-key connection, it has a stronger load-bearing capacity and higher centering accuracy, ensuring that the take-up roller 200 rotates synchronously with the connecting sleeve 101, avoiding uneven winding caused by slippage. The mounting locking assembly 300 employs a combination design of a semi-circular mounting groove 301 and a semi-circular locking bracket 303. The circular hole forms a full-envelope constraint on the mounting rod 202, radially limiting its displacement. The engagement of the locking hole 304 and the locking rod 307 axially locks the locking bracket 303, creating a dual fixation of radial constraint and axial locking, ensuring the mounting rod 202 does not detach from its mounting position during winding. The sliding engagement of the sliding rod 306 and the bracket 305 guides the movement of the locking rod 307, ensuring its precise insertion into the locking hole 304.

[0034] Technical Benefits: This structure achieves rapid positioning and power transmission between the take-up roller 200 and the connecting sleeve 101 via a spline connection, avoiding the cumbersome alignment issues associated with traditional bolt fixing. The design of the mounting locking assembly 300 significantly simplifies the installation and removal process of the take-up roller 200. It eliminates the need to disassemble each bolt individually; fixing and unlocking can be completed simply by rotating the locking bracket 303 and operating the locking rod 307, significantly reducing the time cost of replacing the take-up roller 200. Simultaneously, the full-envelope constraint of the circular hole on the mounting rod 202, combined with the centering effect of the spline connection, ensures the stability of the take-up roller 200 during high-speed rotation, reducing offset or wrinkling during the elastic felt winding process and improving winding quality. The overall structure is compact, with all components working in tandem, making it suitable for elastic felt production scenarios requiring frequent replacement of the take-up roller 200.

[0035] Example 2

[0036] This solution further defines Embodiment 1. A servo geared motor 103 is mounted on the outer wall of the frame 100 via a support frame and bolts. The output shaft of the servo geared motor 103 is fixedly connected to the end of the connecting sleeve 101 away from the spline slot 102 via a coupling.

[0037] Solution Analysis: From the perspective of power transmission and control principles, the servo geared motor 103 serves as the power source. Its output shaft is connected to the connecting sleeve 101 via a coupling. The coupling compensates for the relative displacement between the two shafts (such as coaxiality deviation caused by installation errors), ensuring the smoothness of power transmission. The servo geared motor 103 features adjustable speed and stable output torque. Through the reduction mechanism, high speed can be converted into low speed and high torque required for winding, meeting the tension and speed requirements during elastic felt winding. If the speed is too high, it may cause the elastic felt to stretch and deform; if the speed is too low, it will affect production efficiency. The controllability of the servo motor can precisely match the winding requirements of elastic felt of different thicknesses and materials. The fixing method of the support frame and bolts ensures the stability of the servo geared motor 103 during operation, avoiding loosening of the connection due to vibration and ensuring the continuity of power transmission.

[0038] Technical Benefits: The introduction of the servo geared motor 103 automates and controls the winding process. Compared to traditional manual or ordinary motor drives, it can precisely control the speed and direction of the winding roller 200, ensuring tight and uniform winding of the elastic felt and reducing uneven roll diameter caused by speed fluctuations. The use of a coupling reduces the installation accuracy requirements, facilitating equipment assembly and maintenance. Simultaneously, the stable torque output can adapt to load changes caused by the increased roll diameter during elastic felt winding, preventing downtime or motor damage due to excessive load, thus improving equipment reliability and production continuity.

[0039] Example 3

[0040] This solution further defines Embodiment 1, wherein the locking hole 304 and the locking rod 307 are circular, and the inner diameter of the locking hole 304 is consistent with the outer diameter of the locking rod 307.

[0041] Solution Analysis: From the perspective of mechanical fit principles, the circular locking hole 304 and the locking rod 307 belong to the transition fit in clearance fit (inner diameter and outer diameter are the same). This fit method can ensure that the locking rod 307 can be smoothly inserted into the locking hole 304 while reducing the clearance between them. From a mechanical point of view, the circular structure has uniform force characteristics. When the locking rod 307 is inserted into the locking hole 304, the circumferential contact can make the constraint force on the locking frame 303 evenly distributed, avoiding component deformation caused by local stress concentration. If a non-circular structure (such as a square one) is used, the stress concentration at the corners may cause the locking hole 304 or the locking rod 307 to wear faster, affecting the locking reliability. The design with consistent dimensions eliminates the radial wobble space, ensuring that the locking frame 303 will not loosen due to vibration when the take-up roller 200 rotates.

[0042] Technical Benefits: The circular and uniformly sized design significantly improves the stability of the locking structure. The tight fit between the locking rod 307 and the locking hole 304 reduces mechanical vibration during winding, preventing the mounting rod 202 from shifting due to loosening and ensuring the flatness of the elastic felt winding. Simultaneously, the uniform stress distribution reduces the wear rate of components, extending the service life of the locking hole 304 and the locking rod 307, and reducing the frequency of equipment maintenance. Furthermore, the circular structure facilitates manufacturing, reducing production difficulty and cost, making it suitable for mass production applications.

[0043] Example 4

[0044] This solution further defines embodiment 3. The outer diameter of the locking rod 307 is larger than the outer diameter of the sliding rod 306. A spring 308 in the same direction as the sliding rod 306 is fixed between the locking rod 307 and the bracket 305. The rod body of the sliding rod 306 is located inside the spring 308 and is spaced apart from it.

[0045] Solution Analysis: From the perspective of elasticity mechanics and structural design principles, the design of the locking rod 307 having a larger outer diameter than the sliding rod 306 creates a "step" structure, providing a stable force fulcrum for the spring 308. When the spring 308 is compressed, its elastic force can be transmitted through the stepped surface of the locking rod 307, pushing the locking rod 307 towards the locking hole 304. The spring 308 utilizes its elastic reset characteristic, eliminating the need for manual maintenance of the locking rod 307's insertion state and achieving automated locking. The sliding rod 306 is located inside the spring 308 with a gap, providing radial positioning for the spring 308, preventing it from shifting or twisting during extension and retraction, and reducing friction between the sliding rod 306 and the spring 308. This ensures that the sliding rod 306 can flexibly drive the locking rod 307, reducing operational resistance.

[0046] Technical benefits: The elastic force of the spring 308 ensures that the locking rod 307 always tends to move towards the locking hole 304, guaranteeing the reliability of the locked state and preventing the locking rod 307 from disengaging from the locking hole 304 due to accidental collisions or vibrations. The gap design between the sliding rod 306 and the spring 308 reduces mechanical friction, making the insertion / removal of the locking rod 307 easier and improving operator efficiency. Furthermore, the structure of "large-diameter locking rod 307 + small-diameter sliding rod 306" saves material costs, and the concealed layout of the spring 308 makes the overall structure more compact, reducing the space occupied by the equipment.

[0047] Example 5

[0048] This solution further defines embodiment 4. The spring 308 is used to push the locking rod 307 to move axially toward the direction of the locking hole 304. A pull ring 309 is provided at the end of the sliding rod 306 away from the locking rod 307.

[0049] Solution Analysis: From an ergonomic and mechanical perspective, the pushing direction of spring 308 is aligned with the axial direction of locking rod 307, maximizing the use of elasticity for locking. When sliding rod 306 is released, the restoring force of spring 308 acts directly on the axial direction of locking rod 307, ensuring precise insertion into locking hole 304 and preventing locking failure due to force direction deviation. The pull ring 309 optimizes the operation method. Operators can move sliding rod 306 and locking rod 307 by pulling the pull ring 309. Compared to directly pulling sliding rod 306, pull ring 309 increases the hand contact area, reducing hand pressure during operation, conforming to ergonomic principles and reducing hand fatigue caused by prolonged operation. Furthermore, pull ring 309 provides a clear point of force application, making unlocking more convenient and precise.

[0050] Technical Benefits: The directional thrust of spring 308 ensures the automatic reset of locking rod 307, achieving convenient "lock upon release" operation and reducing locking instability caused by human error. The pull ring 309 design improves operational comfort and efficiency, making the replacement process of take-up roller 200 smoother, especially in scenarios where take-up roller 200 is frequently changed, significantly reducing the operator's workload. Simultaneously, this structural design is simple and reliable, eliminating the need for complex control mechanisms, thus reducing equipment failure rates and maintenance costs.

[0051] Example 6

[0052] This solution further defines Embodiment 1. The mounting groove 301 and the locking bracket 303 are recessed on the side near the mounting rod 202 with an arc-shaped groove 310. A rotating rod 311 is arranged around the center of the circular hole on the inner side of the arc-shaped groove 310. An anti-slip rubber sleeve 312 is fixed on the outer side of the rod body of each rotating rod 311. The outer surface of each anti-slip rubber sleeve 312 is provided with anti-slip texture and fits against the outer wall of the mounting rod 202.

[0053] Solution Analysis: From the perspective of tribology and mechanical transmission principles, the center of the arc-shaped groove 310 coincides with the center of the circular hole, ensuring that the rotating rod 311 can rotate around the axis of the mounting rod 202, matching the rotation trajectory of the mounting rod 202. The rotational characteristics of the rotating rod 311 convert the sliding friction between the mounting rod 202 and the mounting groove 301 and locking bracket 303 into rolling friction. According to tribological principles, rolling friction is much smaller than sliding friction, significantly reducing energy loss and wear during the rotation of the mounting rod 202. The anti-slip texture of the anti-slip rubber sleeve 312 increases the static friction with the mounting rod 202, preventing radial slippage of the mounting rod 202 during rotation. Simultaneously, the rubber material has a certain elasticity, buffering minor vibrations of the mounting rod 202 and reducing noise and impact.

[0054] Technical Benefits: The rolling friction design of the rotating rod 311 reduces the rotational resistance of the mounting rod 202, making the winding process more labor-saving, reducing the load on the servo geared motor 103, and saving energy. The anti-slip texture of the anti-slip rubber sleeve 312 effectively prevents the mounting rod 202 from slipping, ensuring that the rotational speed of the winding roller 200 is consistent with that of the connecting sleeve 101, avoiding uneven tension during elastic felt winding. In addition, the cushioning effect of the rubber material extends the service life of the mounting rod 202 and the rotating rod 311, reduces equipment maintenance costs, and makes the winding process smoother and quieter.

[0055] Working Principle: This solution mainly achieves automatic winding of the elastic felt and rapid replacement of the winding roller through the coordinated operation of mechanical structures. Power Transmission: The servo geared motor 103 drives the connecting sleeve 101 to rotate via a coupling. The connecting sleeve 101 transmits torque to the winding roller 200 by meshing with the splined rod 201 of the winding roller 200 through the splined slot 102, driving its rotation to achieve the winding of the elastic felt. Fixing and Positioning: The splined rod 201 of the winding roller 200 is inserted into the splined slot 102, achieving precise centering and synchronous rotation through the multi-tooth contact of the spline. The mounting rod 202 is placed in the mounting groove 301. After the locking frame 303 rotates and closes around the rotating shaft 302, it forms a circular hole with the mounting groove 301, radially constraining the mounting rod 202. The locking rod 307 is inserted into the locking hole 304 under the thrust of the spring 308, axially locking the locking frame 303, forming a double fixation. For auxiliary stabilization: the rotating rod 311 inside the arc groove 310 rotates with the mounting rod 202, converting sliding friction into rolling friction and reducing resistance; the anti-slip rubber sleeve 312 increases the friction with the mounting rod 202 through anti-slip patterns, preventing slippage and ensuring smooth winding. The entire process, through "power input - torque transmission - structural fixation - auxiliary stabilization," achieves efficient winding of the elastic felt and convenient replacement of the winding roller.

[0056] Technical benefits of implementing this solution: This solution significantly improves the winding efficiency and quality of elastic felt production through optimized structural design. In terms of ease of operation, the combination of spline connection and locking components allows for the replacement of the winding roller without disassembling multiple bolts; it can be completed simply by pulling the pull ring and rotating the locking frame, greatly shortening replacement time, especially suitable for high-frequency replacement scenarios. Regarding winding stability, the high centering accuracy and multi-tooth force transmission characteristics of the spline connection, combined with the double fixing of the locking components, ensure no deviation during high-speed rotation of the winding roller, reducing elastic felt wrinkles; the combination of the rotating rod and the anti-slip rubber sleeve reduces friction loss and prevents slippage, ensuring uniform winding tension. In terms of structural reliability, the reasonable force distribution of each component (such as the directional thrust of the spring and the uniform force distribution of the circular fit) reduces mechanical wear and malfunctions, extending equipment lifespan; the "U"-shaped frame and compact layout design save production space and are adaptable to various workshop environments. Overall, it achieves efficient, stable, and convenient elastic felt winding, possessing strong practical value.

[0057] The specific operation process of the automatic winding mechanism for producing elastic felt is as follows:

[0058] Install the take-up roller: First, pull the pull ring 309 to move the sliding rod 306 and the locking rod 307 away from the locking hole 304, so that the locking rod 307 is pulled out of the locking hole 304, at which time the spring 308 is compressed; rotate the locking frame 303 around the rotating shaft 302 to open it, exposing the mounting groove 301 on the upper edge of the side wall of the frame 100; fit the spline rod 201 at one end of the take-up roller 200 into the spline groove hole 102 of the connecting sleeve 101, and place the mounting rod 202 at the other end in the mounting groove 301; rotate the locking frame 303 to press it down and close it, at which time the locking frame 303 and the mounting groove 301 form a circular hole, which encloses the mounting rod 202; release the pull ring 309, the spring 308 returns to its original state, push the locking rod 307 axially towards the direction of the locking hole 304, so that the locking rod 307 is inserted into the locking hole 304, and the installation and fixing of the take-up roller 200 is completed.

[0059] The winding operation is performed as follows: The servo reduction motor 103 on the outer wall of the frame 100 is started. The output shaft of the servo reduction motor 103 drives the connecting sleeve 101 to rotate through the coupling. The connecting sleeve 101 drives the winding roller 200 to rotate through the spline groove hole 102 and the spline rod 201 to wind up the elastic felt. One end of the elastic felt can be connected to the outside of the winding roller 200 by glue or other means. During the winding process, the rotating rod 311 in the arc groove 310 on the inner side of the mounting groove 301 and the locking frame 303 rotates with the mounting rod 202. The anti-slip rubber sleeve 312 on the outer side of the rotating rod 311 fits against the mounting rod 202 to reduce the friction when the mounting rod 202 rotates. At the same time, the anti-slip texture reduces the possibility of the mounting rod 202 slipping.

[0060] Disassembling the take-up roller: After winding is completed, turn off the servo reduction motor 103 to stop the rotation of the take-up roller 200; pull the pull ring 309 to pull the locking rod 307 out of the locking hole 304, and rotate the locking frame 303 to open it; remove the take-up roller 200 from the connecting sleeve 101 and the mounting groove 301 to complete the disassembly.

[0061] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
