Description

Technical Field

[0001] This utility model relates to the field of tire processing technology, and in particular to a winding device for tire tread production. Background Technology

[0002] The tire manufacturing process typically includes key stages such as raw material preparation, molding, and vulcanization. In the raw material preparation stage, rubber and various auxiliary materials are thoroughly mixed under high temperature, high pressure, and high shear force in an internal mixer to form a rubber compound with specific mechanical properties. Subsequently, these compounds are processed into semi-finished components of different sizes and uses, such as tread sheets, ply layers, and bead wires, through processes like calendering and extrusion. These components are then wound up using specialized winding equipment, providing the material basis for subsequent molding and vulcanization processes. In the molding stage, various semi-finished materials are assembled layer by layer on a tire molding machine according to process requirements, constructing the basic structure of the tire. Finally, through the vulcanization process, the rubber layers of the tire undergo chemical cross-linking under high temperature and high pressure, significantly improving the tire's mechanical strength and wear resistance.

[0003] Regarding the winding stage in the aforementioned manufacturing process, traditional winding equipment typically requires operators to manually align the center of the roll core with the center of the equipment's drive shaft during operations such as assembling the roll core. This process is not only time-consuming and labor-intensive but also demands high operational precision, potentially affecting production cycle time and the winding efficiency of the tire tread film.

[0004] In the prior art, for example, CN222204207U describes a tire tread winding device. This device includes a base plate and support assemblies connected to its top two sides. An I-beam collecting wheel is positioned between the support assemblies. Sliding components are connected to opposite sides of the support assemblies, and drive mechanisms for rotating the I-beam collecting wheel are connected to the sliding components. An electric push rod is connected below the sliding components. The drive mechanism includes a mounting plate and a servo motor mounted on one side. A drive wheel is connected to one side of the top of the mounting plate, and a driven wheel is connected to the other side. The I-beam collecting wheel is guided and limited by guide blocks and calibrated by a V-shaped positioning groove, ensuring that both ends of the I-beam collecting wheel are evenly distributed between the drive and driven wheels, improving assembly efficiency. Subsequently, the electric push rod drives the mounting plate upwards off the ground, and the servo motor drives the drive wheel to rotate, thereby rotating the I-beam collecting wheel and winding the tire tread, improving winding efficiency.

[0005] However, while the aforementioned existing technologies improve winding efficiency, their structural design requires the synchronous operation of telescopic cylinders on both sides and drive motors to achieve winding. The synchronous control of multiple drive motors and telescopic cylinders increases the complexity of control, which is not conducive to the simplification and maintenance of the equipment. Summary of the Invention

[0006] Therefore, this utility model provides a winding device for tire tread manufacturing, which reduces control complexity by simplifying the drive structure.

[0007] To solve the above-mentioned technical problems, this utility model provides a winding device for tire tread manufacturing, comprising:

[0008] The mounting bracket is equipped with a placement structure.

[0009] A rotating frame is rotatably connected to the mounting frame;

[0010] The roller assembly is symmetrically arranged on both sides of the rotating frame, and includes a support wheel and a drive wheel that are rotatably connected to the rotating frame respectively;

[0011] A dual-axis drive device includes a dual-axis motor mounted on the rotating frame, a drive sprocket connected to two drive ends of the dual-axis motor, a transmission sprocket connected to each of the drive sprockets, and a chain connecting the corresponding drive sprocket and the transmission sprocket.

[0012] A rotation drive device drives the rotating frame to rotate along the mounting frame;

[0013] When the take-up roller is placed on the placement structure, the rotation of the mounting frame enables the two passive wheels of the take-up roller to be supported by the corresponding support wheel and drive wheel in each of the roller assemblies, thereby raising the take-up roller.

[0014] In one embodiment of this utility model, the top surface height of the support wheel is higher than the top surface height of the drive wheel, so as to limit the winding roller when the winding roller is descending.

[0015] In one embodiment of this utility model, the mounting frame includes a base plate and two upright plates disposed on the base plate and arranged opposite to each other, and the rotating frame includes a rotating shaft rotatably connected to the two upright plates and two rotating arms mounted on the rotating shaft.

[0016] In one embodiment of this utility model, the placement structure is disposed on the base plate, the roller assembly is mounted on each of the rotating arms, and the dual-axis motor is mounted on one of the rotating arms.

[0017] In one embodiment of this utility model, the rotation drive device is mounted on one of the upright plates and the drive end is connected to the rotation shaft.

[0018] In one embodiment of this utility model, the rotation drive device includes a worm gear reducer motor.

[0019] In one embodiment of this utility model, the placement structure includes a placement block and a placement groove disposed on the placement block. The placement groove is used to support the roller shaft of the take-up roller, and the two sides of the placement block are used to limit the take-up wheels of the take-up roller.

[0020] In one embodiment of this utility model, the placement groove has an inwardly concave arc-shaped structure.

[0021] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0022] I. Simplify the drive structure and reduce control complexity

[0023] This system employs a dual-axis motor to directly drive the two drive sprockets, achieving synchronous rotation of the drive wheels via chain transmission. This replaces the complex multi-motor synchronous control system of traditional systems. The single-casing design of the dual-axis motor reduces the number of motors, avoids synchronization errors caused by multi-motor coordinated operation, thereby reducing control system complexity and improving equipment stability.

[0024] II. The rotating and lifting structure design improves ease of operation.

[0025] The rotating frame is driven to rotate and rise by a rotary drive device, which in turn drives the support wheels and drive wheels to support or release the driven wheels, thus achieving automatic raising and lowering of the take-up roll. This design eliminates the need for manual adjustment of the take-up roll position, reducing manual labor intensity, and avoids the synchronization control problems of traditional telescopic cylinders, further simplifying the mechanical structure.

[0026] III. Anti-slip structure ensures operational safety.

[0027] The design of the support wheel being higher than the drive wheel ensures that the passive wheel is always clamped by the support wheel and the drive wheel when the rotating frame is lowered, preventing the winding roller from slipping or shifting during the lifting process, avoiding equipment damage or safety accidents, and improving operational reliability.

[0028] IV. Modular placement slot design improves loading and unloading efficiency

[0029] The placement slots on the mounting frame provide dedicated positioning space for the take-up rollers, facilitating quick placement and removal of the take-up rollers, reducing equipment downtime, and improving production continuity and efficiency.

[0030] V. Efficient Power Transmission via Sprockets and Chains

[0031] The power of the dual-shaft motor is efficiently transmitted to the drive wheel via chain drive, which then drives the driven wheel and the take-up roller to rotate. Chain drive features high transmission efficiency and low energy loss, ensuring the stability and uniformity of the winding process and improving the quality of tire tread winding.

[0032] VI. Reduce equipment maintenance costs

[0033] The integrated design of dual-axis motors and worm gear reduce the number of components in traditional multi-motor, multi-telescopic cylinder systems, thereby reducing equipment failure rates and maintenance costs, while extending service life.

[0034] It is highly adaptable and compatible with various specifications of take-up rolls.

[0035] By adjusting the lifting amplitude of the worm gear reducer motor, it can be adapted to take-up rolls of different diameters, enhancing the equipment's versatility and flexible production capabilities to meet diverse production needs.

[0036] In summary, this utility model achieves multiple goals—improving winding efficiency, simplifying operation, and enhancing safety—by optimizing the drive structure, lifting mechanism, and transmission system. It also reduces equipment complexity and maintenance costs, demonstrating significant industrial application value. Attached Figure Description

[0051] Reference Figure 1 , Figure 2 As shown, the present invention provides a tire tread fabrication winding device, comprising:

[0052] Mounting bracket 1 is provided with a placement structure 11;

[0053] Rotating frame 2 is rotatably connected to the mounting frame 1;

[0054] The roller assembly 3 is symmetrically arranged on both sides of the rotating frame 2, and includes a support wheel 31 and a drive wheel 32 that are rotatably connected to the rotating frame 2 respectively;

[0055] The dual-axis drive device 4 includes a dual-axis motor 41 mounted on the rotating frame 2, a drive sprocket 42 connected to two drive ends of the dual-axis motor 41, a transmission sprocket 43 connected to each of the drive wheels 32, and a chain 44 connecting the corresponding drive sprocket 42 and the transmission sprocket 43.

[0056] The rotation drive device 5 drives the rotating frame 2 to rotate along the mounting frame 1;

[0057] When the take-up roller 6 is placed on the placement structure 11, the rotation of the mounting frame 1 enables the two passive wheels 61 of the take-up roller 6 to be supported by the corresponding support wheel 31 and drive wheel 32 in each of the roller assemblies 3, thereby raising the take-up roller 6.

[0058] With the above configuration, a dual-axis motor 41 directly drives the two active sprockets 42, and the synchronous rotation of the drive wheel 32 is achieved through chain transmission 44, replacing the complex system of traditional multi-motor synchronous control. The single-casing design of the dual-axis motor 41 reduces the number of motors and avoids the synchronization error problem of multi-motor coordinated operation, thereby reducing the complexity of the control system and improving the stability of the equipment. The rotation and lifting of the rotating frame 2 are driven by the rotation drive device 5, which drives the support wheel 31 and the drive wheel 32 to support or release the driven wheel 61, realizing the automatic lifting and lowering of the take-up roller 6. This design eliminates the need for manual adjustment of the position of the take-up roller 6, reduces the intensity of manual operation, and avoids the synchronization control problem of traditional telescopic cylinders, further simplifying the mechanical structure.

[0059] In one embodiment, the top surface of the support wheel 31 is higher than the top surface of the drive wheel 32 to limit the winding roller 6 as it descends. This ensures that the driven wheel 61 is always held between the support wheel 31 and the drive wheel 32 during the descent of the rotating frame 2, preventing the winding roller 6 from slipping or shifting during lifting and lowering, avoiding equipment damage or safety accidents, and improving operational reliability.

[0060] In one embodiment, the mounting frame 1 includes a base plate 12 and two upright plates 13 disposed on the base plate 12 and disposed opposite to each other, and the rotating frame 2 includes a rotating shaft 21 rotatably connected to the two upright plates 13 and two rotating arms 22 mounted on the rotating shaft 21.

[0061] In one embodiment, the placement structure 11 is disposed on the base plate 12, the roller assembly 3 is mounted on each of the rotating arms 22, and the dual-axis motor 41 is mounted on one of the rotating arms 22.

[0062] In one embodiment, the rotation drive device 5 is mounted on one of the upright plates 13 and the drive end is connected to the rotation shaft 21.

[0063] In addition, in order to facilitate the swinging of the rotating frame 2 and its docking with the take-up roller 6, the height of the side of the rotating arm 22 where the dual-axis motor 41 is installed is higher than the height of the side where the roller assembly 3 is installed.

[0064] In one embodiment, the rotation drive device 5 includes a worm gear reducer motor. By adjusting the lifting amplitude of the worm gear reducer motor, it can be adapted to take-up rollers 6 of different diameters, enhancing the versatility and flexible production capabilities of the equipment and meeting diverse production needs.

[0065] Specifically, the placement structure 11 includes a placement block 111 and a placement groove 112 disposed on the placement block 111. The placement groove 112 is used to support the roller shaft 62 of the take-up roller 6, and the two sides of the placement block 111 are used to limit the take-up wheel 63 of the take-up roller 6.

[0066] In one embodiment, the placement slot 112 has a concave arc-shaped structure. The placement slot 112 on the mounting frame 1 provides a dedicated positioning space for the take-up roller 6, which facilitates the quick placement and removal of the take-up roller 6, reduces equipment downtime, and improves production continuity and efficiency.

[0067] In use, the take-up roller 6 of the tire tread is first rolled into the placement groove 112. Then, the worm gear reducer motor drives the support wheel 31 and the drive wheel 32 to support the driven wheel 61, thereby lifting the take-up roller 6. Then, the dual-shaft motor 41 drives the drive sprocket 42, which in turn drives the chain 44 to move, further driving the transmission sprocket 43 to rotate. This, in turn, drives the driven wheel 61 to rotate via the drive wheel 32, thereby driving the take-up roller 6 to rotate and wind up the tire tread. After winding is completed, the worm gear reducer motor reverses, driving the support wheel 31 and the drive wheel 32 to descend and place the take-up roller 6 on the placement groove 112, waiting to be removed. Since the support wheel 31 is higher than the drive wheel 32, the driven wheel 61 will not slip off and fall off when the support wheel 31 and the drive wheel 32 rotate downwards.

[0068] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
