Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, specifically to a sinusoidal nylon fiber cord cycloidal head. Background Technology

[0002] As a key component of aircraft landing gear systems, aircraft tires play a crucial role in supporting, bearing loads, and cushioning during takeoff, landing, and taxiing. Their complex structure is composed of multiple materials bonded together using specialized processes. The protective layer, a vital component of aircraft tires, is typically located in specific positions within the tire and plays a key role in enhancing its overall performance. When an aircraft is taking off, landing, or taxiing on the runway, it may encounter foreign objects such as stones and metal fragments. The protective layer effectively resists punctures from these objects, reducing the risk of tire punctures and thus ensuring flight safety.

[0003] Currently, commercially available protective films for aircraft tires typically consist of two layers of film and a nylon fiber sandwiched in between. This structure uses a specific process to tightly bond the three components together, aiming to provide additional protection for the tire. The nylon fiber, as a reinforcing material, enhances the puncture resistance of the protective film to some extent due to its high strength and toughness. However, in practical applications, existing protective films still have some limitations in their structural design.

[0004] Arranging the nylon fiber cords into an ideal shape is a crucial step in the production of existing protective films. Taking common straight nylon fiber protective films as an example, although a straight layout is relatively easy to achieve in the manufacturing process, from a performance perspective, straight nylon fibers cannot effectively disperse stress when resisting foreign object punctures like certain specially shaped layouts. Studies have shown that a sinusoidal nylon fiber layout can better guide stress dispersion through its curved structure when subjected to foreign object punctures, thus significantly improving the puncture resistance of the protective film. However, due to the special physical properties of nylon threads—they are relatively stiff and have limited flexibility—precisely arranging them into a sinusoidal shape in actual production presents significant technical challenges. This has led to the current market prevalence of straight nylon fiber protective films, but their performance is relatively weaker. Utility Model Content

[0005] This invention provides a sinusoidal nylon fiber cord cycloidal head, which aims to solve the technical problem that nylon fiber cords are difficult to arrange into a sinusoidal shape in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] This utility model provides a sinusoidal nylon fiber cord cycloidal head, comprising:

[0008] Main framework;

[0009] A pressure roller frame, which is connected to the main frame;

[0010] The upper pressure roller is rotatably mounted within the pressure roller frame;

[0011] The lower pressure roller is rotatably disposed within the pressure roller frame and is parallel to the upper pressure roller and disposed directly below the upper pressure roller.

[0012] A cycloidal module, disposed on the main frame, is movable toward or away from the pressure roller frame; wherein, the cycloidal module includes:

[0013] Base plate;

[0014] The wiring module is mounted on the base plate and can reciprocate along a direction parallel to the axis of the upper pressure roller;

[0015] A motor mounting bracket is mounted on the base plate and on one side of the wiring module; a motor is mounted on the motor mounting bracket.

[0016] A concave cam is connected to the drive shaft of the motor; an elliptical groove is provided on the side of the cam facing away from the motor.

[0017] The drive rod has a sliding unit at one end and is fixed to the cable module at the other end; the sliding unit is slidably embedded in the elliptical groove.

[0018] After the motor is started, it drives the concave cam to rotate; the sliding unit slides relative to the elliptical groove, and the sliding unit reciprocates in a direction parallel to the axis of the upper pressure roller, thereby driving the wiring module to reciprocate through the drive rod.

[0019] Furthermore, the pressure roller frame has two parallel upper and lower sliding rails on each side, each of which is distributed vertically. The two ends of the upper pressure roller are rotatably mounted in the movable pressure roller seat, and each movable pressure roller seat is correspondingly embedded between a set of upper and lower sliding rails, allowing it to slide along the extension direction of the rails. The top of each side of the pressure roller frame has screw holes, and each screw hole is threaded with a screw rod. One end of the screw rod facing the upper pressure roller is fixedly connected to the corresponding movable pressure roller seat, and the other end is fixedly mounted with a handwheel. When the two handwheels are rotated, the screw rod will extend and retract along the axial direction of the screw hole, thereby driving the movable pressure roller seat to reciprocate vertically along the upper and lower sliding rails, ultimately realizing the vertical lifting and lowering of the upper pressure roller.

[0020] Furthermore, both ends of the lower pressure roller are rotatably mounted in the fixed pressure roller seat, and the two fixed pressure roller seats are respectively fixed on both sides of the pressure roller frame.

[0021] Furthermore, front and rear slide rails are respectively provided on the top two sides of the main frame, and the extension direction of the front and rear slide rails is perpendicular to the axis of the upper pressure roller; the bottom of the base plate of the cycloidal module is provided with front and rear sliders, and the front and rear sliders are adapted to the front and rear slide rails; the base plate is mounted on the front and rear slide rails through the front and rear sliders, and can reciprocate along the extension direction of the front and rear slide rails.

[0022] Furthermore, the wiring module includes two side plates and a wiring plate. The two side plates are fixedly connected by a fixing rod, and the wiring plate is fixedly disposed between the two side plates. The wiring plate has a wire inlet groove on the side away from the pressure roller frame, and a plurality of wire outlet needles communicating with the wire inlet groove are provided on the other side facing the pressure roller frame. The spacing between two adjacent wire outlet needles is equal. The axes of all the wire outlet needles are in the same plane, which is parallel to the axis of the upper pressure roller.

[0023] Furthermore, a transverse slide rail is provided on the side of the base plate away from the main frame, and the transverse slide rail is parallel to the axis of the upper pressure roller; both side plates have transverse sliders at their bottoms, and the transverse sliders are set on the transverse slide rails, allowing the wiring module to reciprocate along the transverse slide rails.

[0024] Furthermore, the cycloidal module also includes two fixed plates and a sliding rod. The two fixed plates are parallel to each other and fixed to the base plate at intervals. The cycloidal module is located between the two fixed plates. Each fixed plate has a through hole, and the central axes of the two through holes are collinear. Sliding sleeves are respectively provided on the two side plates. The sliding rod passes through the through hole of one fixed plate, the sliding sleeve of the cycloidal module, the sliding sleeve of the cycloidal module on the other side, and the through hole of the other fixed plate in sequence, and the sliding rod slides in cooperation with the sliding sleeve. Limiting units are provided at both ends of the sliding rod.

[0025] Furthermore, the limiting unit includes a screw rod coaxially connected to the slide rod and a nut disposed on the screw rod.

[0026] Furthermore, the sliding unit includes a vertical rod connected perpendicularly to the drive rod and a bearing disposed on the vertical rod.

[0027] The beneficial effects achieved by this utility model are as follows:

[0028] 1) Achieving precise forming of sinusoidal nylon fiber cords: A motor drives a concave cam to rotate, utilizing the relative motion between an elliptical groove and a sliding unit to drive the cord-laying module in a stable reciprocating motion parallel to the upper pressure roller axis. This overcomes the physical limitations of nylon cords, precisely arranging them into a sinusoidal shape. Compared to traditional straight nylon fiber structures, the sinusoidal layout more effectively disperses stress, significantly improving the puncture resistance of the puncture-resistant layer, thereby enhancing the safety protection capabilities of aircraft tires.

[0029] 2) Flexible and easy-to-adjust structural design: The upper and lower sliding rails on both sides of the pressure roller frame cooperate with the screw and handwheel to flexibly adjust the vertical position of the upper pressure roller, facilitating the adjustment of the pressing force according to the film thickness requirements; the front and rear sliding rails at the top of the main frame cooperate with the bottom plate slider of the cycloidal module, enabling the cycloidal module to move closer to or further away from the pressure roller frame, adapting to the position requirements in different production scenarios. In addition, the sliding cooperation between the slide rod and the sliding sleeve, as well as the setting of the limit unit, ensures stable and non-deviation-free reciprocating motion of the wire-laying module, improving the reliability of equipment operation.

[0030] 3) Improved production efficiency and product consistency: Standardized design and precise coordination of each component ensure seamless operation of processes such as nylon fiber cord arrangement and pressing, reducing errors caused by manual intervention. The evenly distributed lead-out needles and guiding action of the transverse slide rails in the cord laying module guarantee the neatness and consistent spacing of multiple nylon cords, facilitating large-scale production, stabilizing product quality control, and reducing the defect rate.

[0031] 4) Wide applicability and convenient maintenance: The equipment has a compact structure and clear connections between components. For example, the sliding unit uses a bearing structure, and the limit unit uses a screw and nut combination. This not only reduces frictional losses and extends the service life of the equipment, but also facilitates later maintenance and parts replacement. Furthermore, by adjusting the handwheel and slide rail positions, it can be adapted to the production of different specifications of aviation tire puncture-resistant film, enhancing the equipment's versatility.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0046] like Figures 1-9 As shown, this utility model provides a sinusoidal nylon fiber cord cycloidal head, including a main frame 100, a pressure roller frame 200, an upper pressure roller 210, a lower pressure roller 220, a cycloidal module 300, and a control cabinet 500. The components work together to realize the sinusoidal cycloidal arrangement and compression forming of the nylon fiber cord.

[0047] The main frame 100 is welded from square steel tubes to provide stable support for the equipment. Leveling feet are installed at its bottom, connected to the main frame 100 via screws. The overall levelness can be adjusted by rotating the feet. Front and rear slide rails 110 are fixed to the top two sides of the main frame 100 along the front-rear direction. The slide rails have a T-shaped cross-section, and their extension direction is perpendicular to the axis of the subsequently installed upper pressure roller 210. The slide rail surface is hardened to improve wear resistance.

[0048] The pressure roller frame 200 is fixed to one end of the main frame 100 by bolts / welding, specifically the rear end. The pressure roller frame 200 is welded from square steel tubing, and space for installing pressure roller seats is provided on both the left and right sides of the pressure roller frame 200. Two upper and lower sliding rails 240 are welded to the left and right sides of the pressure roller frame 200, respectively. Specifically, two upper and lower sliding rails 240 are provided on the left side and two upper and lower sliding rails 240 are provided on the right side. The cross-sectional shape of each upper and lower sliding rail 240 is T-shaped, and each set of upper and lower sliding rails 240 is parallel to each other and distributed in the vertical direction. Wear-resistant lining strips are embedded on the inner side of the upper and lower sliding rails 240.

[0049] Both ends of the upper pressure roller 210 are respectively assembled in the movable pressure roller seat 250 through deep groove ball bearings. The front and rear sides of the movable pressure roller seat 250 are provided with grooves that match the upper and lower slide rails 240, and are embedded between the two sets of upper and lower slide rails 240 and can slide freely along the slide rails. The left and right sides of the pressure roller frame 200 are respectively provided with screw holes at the center of the top. The axis of the screw holes is perpendicular to the upper and lower slide rails 240, and fine threads are tapped in the holes. The screw passes through the corresponding screw hole and engages with the screw thread. The lower end is fixedly connected to the movable pressure roller seat 250 through a flange, and the upper end is welded with a handwheel 230. The edge of the handwheel 230 is provided with anti-slip texture. When the handwheel 230 is rotated, the screw moves axially along the screw hole, driving the movable pressure roller seat 250 and the upper pressure roller 210 to perform vertical lifting and lowering movements synchronously, so as to realize the adjustment of the distance between the upper and lower pressure rollers 220.

[0050] The two ends of the lower pressure roller 220 are assembled in the fixed pressure roller seat 260 by tapered roller bearings. The fixed pressure roller seat 260 is fastened to the left and right sides of the pressure roller frame 200 by bolts to ensure that the lower pressure roller 220 and the upper pressure roller 210 remain parallel, and the axis of the lower pressure roller 220 is located directly below the axis of the upper pressure roller 210. The axes of the two are in the same vertical plane, forming a roller gap for pressing materials.

[0051] like Figure 6 As shown, the upper pressure roller 210 and the lower pressure roller 220 rotate in opposite directions. The clamping force generated by this reverse rotation can tightly press the two layers of film and the nylon fiber cords therein into one piece, and at the same time stably transport the pressed composite to the next process, thereby working in conjunction with other tooling to complete the production of the tire protective layer.

[0052] In some embodiments, both the upper pressure roller 210 and the lower pressure roller 220 are driven by a motor (not shown in the figure). One end of the upper pressure roller 210 and the lower pressure roller 220 are respectively connected to a drive wheel. Each motor is connected to the corresponding drive wheel through a connection unit such as a belt, a synchronous belt or a gear, so as to drive the upper pressure roller 210 or the lower pressure roller 220 to rotate. The specific connection method is well known to those skilled in the art and will not be described in detail here.

[0053] In some embodiments, the motor driving the lower pressure roller 220 is fixed to the pressure roller frame 200 by a bracket; the motor driving the upper pressure roller 210 is fixed to the housing of the movable pressure roller seat 250 by a bracket, so as to move up and down synchronously with the movable pressure roller seat 250.

[0054] In some embodiments, neither the upper pressure roller 210 nor the lower pressure roller 220 is equipped with a drive motor and is a purely driven pressure roller. In this case, the driving force for conveying the upper and lower film sheets is entirely provided by the equipment in the next process (such as a traction device, a winding machine, etc.). The upper pressure roller 210 and the lower pressure roller 220 generate clamping force only by adjusting the gap, so as to achieve tight clamping and pressing of the two layers of film sheets and the nylon fiber cords therein. They themselves are passively rotated with the material conveying and do not participate in power output.

[0055] The cycloidal module 300 is installed on the top of the main frame 100. Its base plate 310 is made of thick steel plate. The bottom of the base plate 310 is fixed with front and rear sliders 311 that match the front and rear slide rails 110 by bolts / welding. The front and rear sliders 311 are embedded in the front and rear slide rails 110 and can slide along the length of the front and rear slide rails 110. The distance between the cycloidal module 300 and the pressure roller frame 200 can be adjusted by pushing the base plate 310. A locking screw hole is provided on one side of the base plate 310 and a locking handle is provided. A screw is connected to the center of the locking handle and is threaded to the locking screw hole. When the locking handle is rotated, the screw at its end will move axially and press against the front and rear slide rails 110. Through the friction between the screw and the front and rear slide rails 110, the base plate 310 can be firmly fixed in the current position.

[0056] Furthermore, there are a total of four front and rear sliders 311, with two on each of the left and right sides of the base plate 310, meaning that each front and rear slide rail 110 is equipped with two front and rear sliders 311 to ensure the stability of the cycloidal module 300.

[0057] The cycloidal module 300's wiring module 400 includes two side plates 410, a wiring plate 430, and at least two fixing rods 420. The side plates 410 are made of steel plate, and the fixing rods 420 are cylindrical steel rods, with both ends welded and fixed to the two side plates 410 respectively, forming a rectangular frame structure. The wiring plate 430 is fixed between the two side plates 410 by bolts and is located in the middle of the frame. The wiring plate 430 is made of wear-resistant material, and a long strip-shaped inlet groove 431 is opened on the side away from the pressure roller frame 200. The inlet groove 431 has a U-shaped cross-section, and the groove width is larger than the diameter of the nylon fiber cord. Several outlet needles 432 are processed on the side facing the pressure roller frame 200. The spacing between adjacent needles is equal and they are parallel. The axes of all needles are in the same plane, which is parallel to the axis of the upper pressure roller 210. The needles have through holes that communicate with the inlet groove 431 for the nylon fiber cord to pass through.

[0058] At least one parallel transverse slide rail 380 is fixed to the upper surface of the base plate 310 by bolts. The extension direction of the transverse slide rail 380 is parallel to the axis of the upper pressure roller 210. The bottom of the two side plates 410 of the wiring module 400 are respectively installed with transverse sliders 411. The transverse sliders 411 slide with the transverse slide rail 380, so that the wiring module 400 can reciprocate along the transverse direction.

[0059] The cycloidal module 300 also includes two fixing plates 350 and a sliding rod 360. The side projection shape of the fixing plates 350 is 7-shaped. The fixing plates 350 are vertically fixed to the base plate 310 by welding / bolts. The two fixing plates 350 are parallel to each other and the spacing is sufficient to allow the cycloidal module 400 to move laterally. The cycloidal module 400 is located between the two fixing plates 350. Each fixing plate 350 has a through hole on its rear top, and the two through holes are coaxial. The two side plates 410 of the cycloidal module 400 are welded with corresponding sliding sleeves, and the axis of the sliding sleeve is aligned with the axis of the through hole. The slide rod 360 is made of chrome-plated round steel and passes sequentially through the through hole of one side fixing plate 350, the sliding sleeve on one side of the cable module 400, the sliding sleeve on the other side, and the through hole of the other side fixing plate 350. The slide rod 360 and the sliding sleeve are clearance-fitted to ensure that the cable module 400 can slide smoothly left and right along the slide rod 360. Limiting units 361 are respectively provided at both ends of the slide rod 360. The limiting unit 361 includes a screw rod coaxially connected to the slide rod 360 and a nut provided on the screw rod. The slide rod 360 is fixed by simultaneously tightening the nut towards the middle.

[0060] The side projection shape of the motor mounting bracket 340 is 7-shaped. The motor mounting bracket 340 is fixed to the base plate 310 by welding / bolting, located on the right / left side of the wiring module 400. The motor 320 is fixed to the motor mounting bracket 340 by bolts. The motor 320 is a servo motor 320, and its output shaft is arranged vertically. The concave cam 330 is fixed to the output shaft of the motor 320 by key connection. The side end face of the concave cam 330 opposite to the motor 320 is machined with a closed elliptical groove 331. The groove cross-section is U-shaped and matches the sliding unit 371. One end of the drive rod 370 is fixed to the side plate 410 of the wiring module 400 by bolts, and the other end is vertically welded with a plumb line. The end of the plumb line is equipped with a deep groove ball bearing (i.e., the sliding unit 371) through a bearing seat. The outer ring of the bearing is embedded in the elliptical groove 331 and can roll along the inner wall of the elliptical groove 331.

[0061] Furthermore, the horizontal projection shape of the elliptical groove 331 is elliptical.

[0062] When the motor 320 starts, its drive shaft drives the concave cam 330 to rotate. The sliding unit 371 embedded in the elliptical groove 331 cannot rotate with the elliptical groove 331 due to its connection with the drive rod 370 and the wiring module 400. It can only slide relative to the inner wall of the elliptical groove 331. During the rotation of the elliptical groove 331, its inner wall forms a periodic pushing and pulling force on the sliding unit 371, causing the sliding unit 371 to reciprocate relative to the base plate 310. This motion is transmitted to the wiring module 400 through the drive rod 370, which ultimately drives the wiring module 400 to achieve stable reciprocating motion in a direction parallel to the axis of the upper pressure roller 210. This, in conjunction with the upper pressure roller 210 and the lower pressure roller 220, completes the sinusoidal wave-shaped arranging action of the nylon fiber cord by conveying the film backward.

[0063] The control cabinet 500 is an independent enclosure structure, bolted to one side of the main frame 100. Internally, it houses electrical components such as a PLC controller, servo driver, and relays. The external panel features a touchscreen, emergency stop button, start / stop button, and indicator lights. The control cabinet 500 is connected to the motor 320 and the upper pressure roller 210 drive motor 320 (if it is an active roller) via wires. Parameters such as the motor 320 speed and the reciprocating frequency of the wiring module 400 can be set via the touchscreen to achieve automated control of the equipment.

[0064] The control cabinet 500 involved in this application is prior art. It is used for routine control of the operation of the cycloidal head and can be implemented using conventional electrical control devices known to those skilled in the art. Those skilled in the art can easily select and set it up based on conventional knowledge. Therefore, no additional explanation is given here regarding its specific structure and control logic.

[0065] Work process:

[0066] S1. Lay the upper film on the surface of the upper pressure roller 210 in the direction of rotation, and lay the lower film on the surface of the lower pressure roller 220 in the direction of rotation, to ensure that the conveying directions of the two film layers are consistent.

[0067] S2. Select an appropriate number of nylon fiber cords according to production needs, insert each cord into the inlet slot 431 of the cable tray 430, lead it out through the corresponding outlet needle 432, pass through the gap between the upper pressure roller 210 and the lower pressure roller 220, and lay it flat on the preset position of the lower film.

[0068] S3. Simultaneously rotate the handwheels 230 on both sides of the pressure roller frame 200 to drive the upper pressure roller 210 to move vertically downward along the upper and lower slide rails 240 until it presses the two layers of film and nylon fiber cord together with the lower pressure roller 220. The pressing force is ensured to meet the production requirements by using the feel of the handwheel 230, the preset scale, or the preset number of rotations.

[0069] S4. Push the cycloidal module 300 to move along the front and rear slide rails 110 at the top of the main frame 100, so that the wire outlet needle 432 of the wire laying module 400 is aligned with the pressing position of the upper and lower pressure rollers 220, and tighten the locking handle on one side of the base plate 310 to fix the position of the cycloidal module 300.

[0070] S5. Set parameters such as motor speed of 320 and reciprocating frequency of 400 on the 500 touch screen of the control cabinet, and press the start button to start the equipment.

[0071] S6. After the motor 320 starts, it drives the concave cam 330 to rotate. The elliptical groove 331 on its end face, through the cooperation of the inner wall with the sliding unit 371 (bearing), forces the bearing to roll along the groove trajectory. Then, through the drive rod 370, it drives the wiring module 400 to reciprocate along the transverse slide rail 380. At the same time, the upper pressure roller 210 and the lower pressure roller 220 rotate synchronously under the drive of the drive motor 320. During the process of conveying the pressing film backward, the nylon fiber cord is driven to form a continuous sinusoidal trajectory with the reciprocating motion of the wiring module 400.

[0072] S7. After the unwinding machine releases the film, the upper pressure roller 210 and the lower pressure roller 220 rotate continuously and synchronously, tightly pressing the two layers of film holding the sinusoidal nylon fiber cord into one piece. At the same time, the pressed composite is conveyed to the next process, cooperating with other equipment to realize the continuous production of the sinusoidal protective layer.

[0073] In this embodiment, the connection relationship and movement trajectory of each component are defined by a specific structure to ensure stable operation of the equipment and meet the production requirements of sinusoidal nylon fiber cord.

[0074] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
