Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, and in particular to a cord yarn winding machine. Background Technology

[0002] Tire cords are made of multiple layers of rubber-impregnated cords bonded together with rubber, serving to enhance the overall strength of the tire and stabilize the outer tire. During tire production, the cords need to be slit to meet the width requirements of different specifications and models. The slit cords then need to be wound up separately.

[0003] Traditional winding machines mostly use motors to drive through open gears or long shaft systems. This structure not only has low transmission efficiency and high noise, but also makes equipment maintenance inconvenient due to its complex structure and large space occupation. During the winding process, especially when an emergency stop or precise control of the winding position is required, existing equipment often lacks a dedicated braking system that can respond quickly, brake smoothly, and has adjustable braking torque. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a curtain winding machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cord rewinding machine includes a base and further includes...

[0007] The take-up roller is rotatably supported on the machine base by a bearing assembly. The first end of the take-up roller is provided with a cord forming cylinder, and the second end is drivenly connected to a transmission mechanism.

[0008] A drive unit, mounted on the machine base, has its output end connected to the take-up roller via a transmission mechanism to drive the take-up roller to rotate; and

[0009] A braking device is provided on the top of the machine base for braking the take-up roller.

[0010] Furthermore, the transmission mechanism includes a driving wheel, a driven wheel, and a timing belt. The driving wheel is driven to the output end of the drive device, the driven wheel is driven to the end of the take-up roller away from the cord forming cylinder, and the timing belt connects the driving wheel and the driven wheel.

[0011] Furthermore, the outer wall of the yarn forming cylinder is provided with yarn perforations along its axial direction, the width of the yarn perforations is greater than the thickness of the yarn, and the starting end of the yarn passes through the yarn perforations.

[0012] Furthermore, it also includes at least two bearing housing units arranged at intervals along the axial direction of the take-up roller, each bearing housing unit being provided with a bearing; the roller shaft of the take-up roller passes through and is supported in the inner ring of the bearing.

[0013] Furthermore, the bearing housing unit is a continuous bearing, which includes a bearing housing body and a rolling bearing pre-installed in the bearing housing body.

[0014] Furthermore, the braking device is disposed in the interval region between the at least two bearing housing units, and the braking part of the braking device directly acts on the roller body surface of the take-up roller located in this interval region.

[0015] Furthermore, the braking device is any one of a disc brake, a drum brake, or an electromagnetic brake, which brakes the take-up roller by friction.

[0016] Furthermore, it also includes a tension control device that is signal-connected to the drive device or the take-up roller, for real-time monitoring and adjustment of the tension of the cord yarn during the take-up process.

[0017] Furthermore, a yarn guiding device is also provided on the machine base on the yarn feeding side of the take-up roller. The yarn guiding device includes at least one yarn guiding roller for guiding the cord yarn onto the take-up roller for winding.

[0018] The beneficial effects of this utility model are:

[0019] 1. The present invention proposes a cord winder that organically integrates the drive device, transmission mechanism and braking device on the machine base. The integrated design significantly reduces the external space occupied by the equipment, simplifies the overall structure, and thus improves the overall rigidity and operational reliability of the equipment, making it suitable for long-term continuous and stable production operations in industrial environments.

[0020] 2. The cord rewinding machine proposed in this utility model uses a transmission mechanism consisting of a drive wheel, a driven wheel and a synchronous belt for power transmission. This not only has high transmission efficiency and can effectively reduce energy loss, but also runs smoothly and has low noise. Its inherent buffering and vibration absorption characteristics can smooth the fluctuation of the output torque of the drive device and provide uniform rotational power to the winding roller, which is conducive to ensuring the stability of the cord winding process.

[0021] 3. The cord rewinding machine proposed in this utility model supports the winding roller by at least two bearing seat units arranged at intervals along the axial direction, providing span support for the roller body, which greatly enhances its rigidity and dynamic balance accuracy during rotation. It can effectively suppress the radial runout and deformation of the winding roller under high speed and heavy load, and ensures from a mechanical structure perspective that the cord can be wound tightly and neatly with straight edges, fundamentally avoiding quality defects such as loose inside and tight outside, bulging or collapsed edges.

[0022] 4. The curtain yarn winding machine proposed in this utility model, by setting a curtain yarn forming cylinder, makes the operation of threading, guiding and unwinding yarn extremely simple and quick, significantly reducing the labor intensity of operators and improving work efficiency. At the same time, the standardization of the transmission mechanism and support components also makes daily maintenance, upkeep and replacement of vulnerable parts more convenient.

Detailed Implementation

[0027] The following is combined Figures 1-2 This utility model will be described in detail.

[0028] A cord rewinding machine includes a base 10, and also includes...

[0029] The take-up roller 20 is rotatably supported on the base 10 by a bearing assembly. The first end of the take-up roller 20 is provided with a cord forming cylinder 201, and the second end is connected to a transmission mechanism.

[0030] A drive unit 40 is disposed on the base 10, and its output end is connected to the take-up roller 20 via a transmission mechanism to drive the take-up roller 20 to rotate; and

[0031] A braking device 60 is provided on the top of the base 10 for braking the take-up roller 20. In order to achieve precise control of the take-up process and emergency braking, it can slow down or stop the roller when needed.

[0032] The take-up roller 20 is rotatably mounted on the base 10 via a bearing housing. The first end of the take-up roller 20 is provided with a yarn forming cylinder 201 for fixing and initiating the winding of the yarn, and the second end is connected to a transmission mechanism. A drive unit 40, which provides power to the entire device, is fixedly mounted inside or on the base 10. Its output end is connected to the take-up roller 20 via the aforementioned transmission mechanism, thereby transmitting power to the take-up roller 20 and driving it to perform a rotating winding operation.

[0033] In this embodiment, the transmission mechanism includes a drive wheel 501, a driven wheel 502, and a timing belt 503. The drive wheel 501 is driven to the output end of the drive device 40, the driven wheel 502 is driven to the end of the take-up roller 20 away from the cord forming cylinder 201, and the timing belt 503 connects the drive wheel 501 and the driven wheel 502.

[0034] The driven pulley 502 is fixedly mounted on the output shaft of the drive unit 40 and rotates together with the motor shaft; the driven pulley 502 is fixedly mounted on the second end of the take-up roller 20, that is, the end away from the yarn forming cylinder 201. A synchronous belt 503 is tensioned and fitted onto the driven pulley 501 and the driven pulley 502. When the drive unit 40 is started, the driven pulley 501 drives the driven pulley 502 to rotate synchronously via the synchronous belt 503, thereby efficiently and smoothly transmitting power to the take-up roller 20.

[0035] In this embodiment, the outer wall of the curtain forming cylinder 201 is provided with a curtain perforation 2011 along its axial direction. The width of the curtain perforation 2011 is greater than the thickness of the curtain, and the starting end of the curtain passes through the curtain perforation 2011.

[0036] Specifically, the forming cylinder 201 is a hollow cylindrical body, with its outer cylindrical surface forming the actual winding surface of the cord. To achieve a tight fit and power transmission with the take-up roller 20, the forming cylinder is detachably fitted and fixed to the first end of the take-up roller 20 through connecting structures at both ends. Specifically, an internal spline or a non-circular embedded hole can be provided inside one end to engage with the external spline or drive key fixedly installed at the corresponding end of the take-up roller 20, ensuring that the rotational torque of the take-up roller 20 can be completely transmitted to the forming cylinder and preventing relative slippage between the two. On the cylindrical wall of the forming cylinder, one or more cord starting grooves or cord through holes 2011 are usually provided, with a width or diameter slightly larger than the thickness of the cord. The operator can pass the starting end of the cord through the hole or embed it into the groove, thereby firmly clamping the end of the cord at the start of winding. As the forming cylinder rotates, the cord can smoothly begin to wind layer by layer.

[0037] In this embodiment, at least two bearing housing units 30 are arranged at intervals along the axial direction of the take-up roller 20, and each bearing housing unit 30 is provided with a bearing; the roller shaft of the take-up roller 20 passes through and is supported in the inner ring of the bearing.

[0038] The take-up roll 20 is supported by at least two bearing housing units 30 arranged at a certain distance along its axial direction. Each bearing housing unit 30 has a bearing installed inside, and the roll shaft of the take-up roll 20 is precisely inserted into the inner ring of these bearings, thereby ensuring the stability and concentricity of the take-up roll 20 during high-speed rotation and effectively reducing the radial runout of the roll body.

[0039] In this embodiment, the bearing housing unit 30 is a continuous bearing, which includes a bearing housing body and a rolling bearing pre-installed in the bearing housing body.

[0040] The aforementioned bearing housing unit 30 can be a continuous bearing, including a bearing housing body that is easy to install and fix, and a rolling shaft pre-installed in the bearing housing body, which makes the assembly process of the whole machine simpler and faster, while ensuring the accuracy and reliability of the bearing support.

[0041] In this embodiment, the braking device 60 is disposed in the interval area between the at least two bearing housing units 30, and the braking part of the braking device 60 directly acts on the roller surface of the take-up roller 20 located in this interval area.

[0042] The braking device 60 is positioned within the interval region between the at least two bearing housing units 30. The braking component of the braking device 60, such as a brake pad or brake block, acts directly on the surface of the take-up roll 20 located within this interval region. This centrally positioned arrangement allows the braking torque to be applied more evenly to the take-up roll 20, avoiding roll deformation or bearing damage that could occur due to biased braking, thus improving braking stability and safety.

[0043] In this embodiment, the braking device 60 is any one of a disc brake, a drum brake, or an electromagnetic brake, which brakes the take-up roller 20 by friction.

[0044] In one embodiment, a disc brake can be used, which achieves braking by clamping a brake disc mounted on the roller shaft; in another embodiment, a drum brake can be used, which achieves braking by spreading the brake shoes and rubbing against the inner wall of the brake drum that rotates with the roller; or, a fast-responding electromagnetic brake can also be used. These braking devices 60 all achieve reliable braking of the take-up roller 20 mainly through friction.

[0045] In this embodiment, a tension control device connected to the drive device 40 or the take-up roller 20 is also included, which is used to monitor and adjust the tension of the cord yarn in real time during the take-up process.

[0046] To improve winding quality, this equipment can also integrate a tension control device. This tension control device is connected to the drive unit 40 or the winding roller 20 via a signal. It can monitor the tension changes of the cord yarn in real time during the winding process, and dynamically adjust the actual tension of the cord yarn according to the preset tension value by adjusting the speed of the drive unit 40 or through other actuators, ensuring consistent winding tightness and good forming.

[0047] In this embodiment, a yarn guiding device is also provided on the base 10 on the yarn feeding side of the take-up roller 20. The yarn guiding device includes at least one yarn guiding roller for guiding the cord yarn to the take-up roller 20 for winding.

[0048] A yarn guiding device is installed on the base 10 on the yarn feeding side of the take-up roller 20. This yarn guiding device includes at least one freely rotatable yarn guiding roller, which the cord yarn passes over before being wound onto the take-up roller 20. The function of the yarn guiding roller is to guide and position the cord yarn, so that it can be wound smoothly and orderly onto the take-up roller 20 according to a preset path, effectively preventing yarn overlap, deviation, or wear.

[0049] The curtain yarn winding machine provided by this utility model is used as follows:

[0050] The operator first starts the drive unit 40, the drive motor is powered on and runs, and drives the take-up roller 20 to start rotating slowly and smoothly through the transmission mechanism. At this time, the brake device 60 is in a fully released state and will not generate any resistance to the operation of the take-up roller 20. The equipment enters the waiting state.

[0051] The operator leads out the starting end of the formed cord fabric to be wound and manually and securely inserts it into and fixes it onto the cord forming cylinder 201 at the first end of the take-up roller 20. This operation is performed by inserting the cord end into the cord perforation 2011 of the cord forming cylinder 201 to ensure that the cord fabric does not slip or come loose during the initial winding stage.

[0052] After the end of the cord fabric is reliably fixed, the take-up roller 20 rotates at a preset speed under the drive of the drive device 40, and begins to wind the cord fabric. During this process, the tension control device monitors and adjusts the tension of the cord fabric in real time to ensure that it is constant; at the same time, the yarn guide device guides the cord fabric to make regular reciprocating motion along the axial direction of the take-up roller 20, so that it can be smoothly wound layer by layer on the outer surface of the cord fabric forming cylinder 201 until the preset number of turns is completed or the predetermined roll diameter is reached, forming a tight and neat cord fabric roll.

[0053] Once the winding reaches the predetermined requirements, the drive unit 40 stops operating, and then the braking device 60 activates to quickly and smoothly brake the take-up roller 20, bringing it to a precise stop in a convenient operating position. The operator cuts the cord yarn and then uses a specific release mechanism to remove the rolled cord yarn product from the cord forming cylinder 201 as a whole, completing the unloading operation.

[0054] The removed complete curtain roll, as a semi-finished or finished product, is transported away from the winding station and fed into the next process, such as packaging, quality inspection, lamination, or direct shipment to the customer, by manual or automated conveying equipment, thus completing the entire working cycle of the curtain winding machine.

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
