Description

Technical Field

[0001] This utility model relates to the field of textile production technology, specifically to a braking device for a fabric winding machine and the fabric winding machine itself. Background Technology

[0002] During the production and operation of a fabric rolling machine, the fabric output machine, as a crucial piece of equipment in the fabric rolling production process, is prone to fabric wrinkling at its tail end during fabric transport. This phenomenon directly affects the production quality of the fabric and the efficiency of subsequent processing. To solve this wrinkling problem, existing technologies typically involve manually winding the fabric strips onto the guide rollers. However, this operation relies on manual labor, is cumbersome, and labor-intensive. Furthermore, the tightness of the winding is difficult to control precisely, leading to unstable fabric tension. This not only fails to fundamentally and reliably solve the fabric wrinkling problem but may also further affect the smoothness of the fabric due to uneven tension, causing numerous inconveniences in production operations and failing to meet the actual requirements for ease of operation, stability, and product quality in the fabric rolling production process. Summary of the Invention

[0003] The purpose of this utility model is to provide a braking device for a fabric winding machine and a fabric winding machine, which includes a drive assembly disposed below the guide roller, a brake assembly containing brake pads and an adjustment assembly, and a control assembly electrically connected to the drive assembly. The brake pads of the brake assembly are connected to the output end of the drive assembly through the adjustment assembly and match the outer contour of the guide roller. The brake pads reduce the rotation speed of the guide roller by friction braking the guide roller, thereby reducing the speed at which the fabric is released, thereby improving the tension of the fabric unwinding and solving the problem of easy wrinkling of the fabric surface at the tail of the fabric machine in the production of existing fabric winding machines.

[0004] To achieve the above-mentioned technical objectives, this utility model is implemented through the following technical solution: A braking device for a fabric winding machine, comprising: A drive assembly is located below the guide roller; A braking assembly includes a brake pad connected to the output end of the drive assembly via an adjustment assembly, and the brake pad matches the outer contour of the guide roller, and the brake pad is in close contact with the outer side wall of the guide roller under the drive of the drive assembly. A control component, which is electrically connected to the drive component.

[0005] In this solution, by placing the drive assembly below the guide roller, along with a brake pad matching the outer contour of the guide roller and an adjustment assembly connected to the output end of the drive assembly, and combined with a control assembly electrically connected to the drive assembly, the drive assembly can drive the brake pad to press tightly against the outer wall of the guide roller to achieve friction braking under the control of the control assembly. This effectively adjusts the rotation speed of the guide roller, thereby stabilizing the tension during fabric transmission. This solves the problems of cumbersome operation, high labor costs, and low tension control accuracy when using traditional manual fabric strip winding guide rollers to handle fabric wrinkling. It avoids fabric wrinkling and damage to flatness caused by uneven tension, while simplifying the operation process, reducing labor costs, improving the convenience, stability, and product quality of fabric roll production, and better meeting the actual needs of fabric roll production.

[0006] As a further embodiment of the braking device, the braking assembly further includes a connecting post and a locking ring, and the driving assembly includes a telescopic rod; One end of the connecting column is connected to the adjusting component, and the other end of the connecting column is threadedly connected to the telescopic rod through the locking ring. This allows the connecting column to be quickly and securely fixed to the output end of the drive component, and also facilitates the disassembly, maintenance or replacement of the component later.

[0007] As a further embodiment of the braking device, the end of the connecting column is also provided with a connecting block. The radial cross-section of the connecting block is polygonal, and the end of the telescopic rod is provided with a connecting groove that matches the connecting block. When the connecting column and the telescopic rod are connected, the polygonal connecting block can fit into the connecting groove, effectively restricting the relative rotation of the two in the circumferential direction and preventing slippage or displacement between components caused by the torque generated by power transmission during the operation of the braking device.

[0008] As a further embodiment of the braking device, the adjusting assembly includes a locking pin, a mounting base, and a first adjusting block; The mounting base is connected to the end of the connecting column, and a mounting groove matching the first adjusting block is provided in the middle. The locking column passes through the mounting base and the first adjusting block and is locked by a nut. This not only achieves a stable connection between the first adjusting block and the mounting base, but also allows for flexible adjustment of the position of the first adjusting block in the mounting groove by loosening the nut. This adjusts the contact angle and distance between the brake pad and the guide roller, ensuring that the brake pad always maintains a good fit with the outer contour of the guide roller, thus guaranteeing uniform contact and stable braking effect during braking.

[0009] As a further embodiment of the braking device, the adjusting assembly includes a locking pin, a mounting base, a first adjusting block, and a second adjusting block; The mounting base is connected to the end of the connecting column, and its middle part is provided with a mounting groove that matches the first adjusting block and the second adjusting block. The locking column passes through the mounting base, the first adjusting block and the second adjusting block, and is locked by a nut. The first adjusting block is sleeved on the locking post, and the second adjusting block is fixedly connected to the side wall of the mounting groove. The first adjusting block and the second adjusting block are engaged by a meshing part. By utilizing the tooth surface transmission characteristics of the meshing part, the adjustment action of the first adjusting block can be transmitted to the second adjusting block, thereby achieving precise control of the brake pad angle and position, making the fit between the brake pad and the guide roller more accurate and the force more uniform, and greatly improving the stability of the braking effect.

[0010] As a further embodiment of the braking device, the non-engaging end of the first adjusting block is provided with a second tightening part, and the end of the locking pin is provided with a first tightening part that abuts against the second tightening part. The abutting fit between the tightening parts can form a reliable force transmission path, preventing the first adjusting block from shifting due to factors such as vibration and braking impact after adjustment, and ensuring the locking stability of the adjustment position.

[0011] As a further solution to the braking device, the side wall of the first adjusting block is fixedly connected to the clamping arm via a connecting arm. The clamping arm is connected to the brake pad via bolts, which realizes the reliable fixation of the brake pad and the clamping arm. It also has the advantage of easy disassembly, which facilitates replacement and maintenance according to the wear of the brake pad in the future, and reduces the cost of use.

[0012] As a further embodiment of the braking device, the contact surface between the brake pad and the guide roller is provided with evenly distributed friction strips to increase the friction coefficient between the brake pad and the guide roller, effectively preventing slippage during braking and ensuring that the braking assembly can apply a stable and uniform friction force to the guide roller.

[0013] As a further embodiment of the braking device, the control component includes a sensor for detecting the rotational speed of the guide roller. The sensor is electrically connected to the drive component, enabling timely capture of the rotational speed of the guide roller and automatically sending a corresponding control signal to the drive component. The drive component responds quickly and drives the brake pads to adhere tightly to the guide roller to perform the braking action. Tension adjustment can be completed without manual intervention, greatly improving operational convenience and reducing labor costs.

[0014] A fabric rolling machine includes at least one set of the above-described braking devices, the braking devices being located at the end of the guide roller.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. This utility model automatically detects the rotation speed of the guide roller and triggers braking through the sensor of the control component, or can complete the tension adjustment by means of simple manual operation, without relying on repeated manual winding, thus reducing labor costs and operational complexity and improving production efficiency; 2. The brake pad of this utility model matches the outer contour of the guide roller, which can achieve uniform and stable friction braking on the guide roller, effectively adjust the speed of the guide roller to maintain the balance of fabric tension, solve the problem that the manual strip winding method in the prior art is difficult to control tension and causes the fabric surface to wrinkle, and at the same time avoid the impact of uneven tension on the flatness of the fabric, significantly improving the product quality and subsequent processing adaptability of roll fabric production.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example 1

[0019] This embodiment 1 provides a braking device for a fabric rolling machine, such as... Figure 1 As shown, it includes a drive assembly 10, a brake assembly, and a control assembly; Among them, such as Figure 1 and Figure 2 As shown, the drive assembly 10, serving as the power output core, is located below the guide roller 1. It includes a telescopic rod 9, which is preferably a pneumatic telescopic rod, characterized by rapid response and stable power, and can achieve telescopic movement according to control signals. The brake assembly is equipped with a connecting post 7 and a locking ring 8. The connecting post 7 has a cylindrical structure, with one end used to connect to the adjustment component of the brake assembly. The connecting post 7 is threadedly locked to the telescopic rod 9 by the locking ring 8, ensuring the stability of the connection between the connecting post 7 and the telescopic rod 9 and preventing loosening during braking.

[0020] In other embodiments, the end of the connecting post 7 is also integrally formed with a connecting block 16. The radial cross-section of the connecting block 16 is set as a regular hexagon (or other polygonal structures such as squares or regular pentagons can be used according to actual needs). The end of the telescopic rod 9 is provided with a polygonal connecting groove that perfectly matches the shape and size of the connecting block 16. When the connecting post 7 and the telescopic rod 9 are connected, the connecting block 16 is embedded in the connecting groove, effectively restricting the relative rotation of the two in the circumferential direction and preventing the components from slipping or displacing due to torque during power transmission.

[0021] Among them, such as Figures 3-5 As shown, the above-mentioned brake assembly is a brake actuator, and also includes brake pads 2, clamping arms 3 and connecting arms 4; like Figure 3 As shown, the brake pad 2 is made of wear-resistant rubber material, and its contour is perfectly matched with the outer contour of the guide roller 1, ensuring full contact and uniform force when it is in contact with the side wall of the guide roller 1. Furthermore, the contact surface between the brake pad 2 and the guide roller 1 is integrally formed with evenly distributed friction strips 15. The friction strips 15 are arranged parallel to the circumference of the brake pad 2 with a spacing of 5-8mm. By increasing the friction coefficient of the contact surface, slippage during braking is effectively avoided, ensuring the stability of the braking effect. At the same time, the brake pad 2 is detachably connected to the clamping arm 3 by bolts, which facilitates later maintenance and replacement.

[0022] like Figure 4 and Figure 5 As shown, the clamping arm 3 is an arc-shaped plate structure that fits snugly against the mounting surface of the brake pad 2. Bolt holes are provided at both ends of the clamping arm 3, and the brake pad 2 is fixed to the clamping arm 3 by bolts. The middle part of the clamping arm 3 is welded to one end of the connecting arm 4, which is a rigid metal rod. The other end of the connecting arm 4 is welded to the first adjusting block 11 of the adjusting assembly, forming a rigid transmission structure to ensure that the adjusting action and driving force can be transmitted to the brake pad 2.

[0023] Please refer to the following: Figure 5 The aforementioned adjustment components specifically include a locking pin 5, a mounting base 6, and a first adjustment block 11. The mounting base 6 is a cuboid block structure, with its bottom welded to the end of the connecting pin 7. A rectangular mounting groove matching the shape of the first adjustment block 11 is provided in the middle. The first adjustment block 11 is a cylindrical structure, fitted onto the locking pin 5. The locking pin 5 passes through the side wall of the mounting base 6 and the first adjustment block 11 in sequence, and its end is locked and fixed by a nut 14. When the nut 14 is loosened, the first adjustment block 11 can be rotated along the axial direction of the locking pin 5 to adjust the first adjustment block 11, thereby finely adjusting the contact angle between the brake pad 2 and the guide roller 1. After adjustment, tightening the nut 14 locks the position.

[0024] The control components include a speed sensor (not shown in the figure) and a controller. The speed sensor is a Hall sensor, installed on the end bearing seat of the guide roller 1, used to detect the speed data of the guide roller 1 in real time and transmit the data to the controller. The controller is electrically connected to the drive component 10. When the sensor detects that the speed of the guide roller 1 exceeds the reference range, the controller automatically sends a control signal to the telescopic rod 9, driving the telescopic rod 9 to retract and push the brake pad 2 to press against the guide roller 1 to perform a braking action until the speed of the guide roller 1 returns to the reference range. When the speed is normal, the controller controls the telescopic rod 9 to extend, causing the brake pad 2 to separate from the guide roller 1 and stop braking. At the same time, the controller is also equipped with a manual control button, which can be manually triggered to realize the braking action, flexibly adapting to different production scenarios. Example 2

[0025] This embodiment 2 provides another braking device for a fabric rolling machine based on the solution of embodiment 1, such as... Figure 5 and Figure 6 As shown, the difference lies in that the adjustment component in this embodiment includes a locking pin 5, a mounting base 6, a first adjustment block 11, and a second adjustment block 13.

[0026] The structure of mounting base 6 is consistent with that of scheme one, with its central mounting groove adapted to the installation of the first adjusting block 11 and the second adjusting block 13. The second adjusting block 13 is fixedly connected to the side wall of the mounting groove, and the first adjusting block 11 is sleeved on the locking post 5. The opposite end faces of the two are provided with meshing parts 12 that engage with each other. The meshing parts 12 have a sawtooth structure with a tooth pitch of 2-3mm, and the angle adjustment is achieved through tooth surface transmission.

[0027] Meanwhile, the non-engaging end of the first adjusting block 11 is provided with a second tightening part 18, and the end of the locking pin 5 is provided with a first tightening part 17 that abuts against the second tightening part 18; when the locking pin 5 is rotated, the first tightening part 17 pushes the second tightening part 18, driving the first adjusting block 11 and the second adjusting block 13 to clamp together. Example 3

[0028] This embodiment 3 provides a fabric winding machine, including a frame, a guide roller 1, a feed roller, a take-up roller, and at least one set of braking devices as described in Embodiment 1 or Embodiment 2. The braking devices are installed at the end of the guide roller 1 and fixed to the frame by bolts. When the fabric winding machine is working, the feed roller releases the fabric, which is guided and transmitted to the take-up roller by the guide roller 1 for winding. The braking device monitors the rotation speed of the guide roller 1 in real time, and stabilizes the fabric tension by adjusting the rotation speed of the guide roller 1, effectively preventing wrinkling of the fabric surface and improving the quality of fabric winding and production efficiency. Depending on the specifications of the fabric winding machine, a set of braking devices can be installed at each end of the guide roller 1 to achieve bidirectional synchronous braking, further improving the uniformity and stability of the braking effect.

[0029] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
