Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to a winding mechanism for a winding machine. Background Technology

[0002] Winding machines are common pieces of equipment in industrial production, widely used in metallurgy, textiles, plastics processing, and other fields. Their main function is to wind continuously produced strip, wire, or film materials into neat rolls for subsequent storage, transportation, and reprocessing. The winding mechanism, as the core actuator of the winding machine, directly determines the quality of the roll and the overall production efficiency.

[0003] Traditional winding mechanisms typically consist of a motor-driven core onto which the strip is drawn and rotates to complete the winding process. However, once the strip reaches a predetermined length or weight, these traditional winding mechanisms often require operators to manually stop the equipment and laboriously unload the heavy roll from the core. This process is not only labor-intensive and time-consuming, but also prone to causing the roll to loosen or become damaged due to improper operation during unloading, thus affecting product quality.

[0004] To address these issues, some winding mechanisms with automatic unwinding functions have emerged. However, the unwinding devices in these existing technologies are often relatively simple in structure, such as using a cylinder to directly push the material out. This method generates significant impact force, resulting in unstable start-stop operation and making it difficult to precisely control the speed and position of the unwinding process. Especially when processing thin, brittle precision materials such as amorphous ribbons, the severe impact and unstable unwinding process can easily lead to edge damage or internal stress, severely impacting yield and product performance. Furthermore, the control of the number of winding turns often relies on simple timing or length counting methods, which have limited accuracy and cannot meet the requirements of high-precision production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a winding mechanism for a winding machine, which aims to improve the problems of manual unwinding after winding, low degree of automation, and low control accuracy of winding and unwinding processes.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a winding mechanism for a winding machine, comprising: a support assembly, and a winding assembly disposed on the support assembly, the winding assembly comprising a winding motor, a drive wheel, a driven wheel, a synchronous belt, a transmission shaft, a first bearing seat, and a core; and an unloading assembly.

[0007] The unloading assembly includes a transverse motor, a lead screw, a guide rail, a slider, and a chuck. The slider is threadedly engaged with the lead screw and slidably mounted on the guide rail. The chuck is rigidly connected to the slider.

[0008] Furthermore, the claws of the unloading assembly abut against the first bearing seat of the winding assembly, and the linear movement of the slider drives the first bearing seat, the drive shaft and the core to move axially synchronously.

[0009] Preferably, the support assembly includes a mounting base and a connecting plate, with a first support plate and a second support plate fixed on the connecting plate, and the winding motor mounted on the first support plate.

[0010] Preferably, the mounting base is provided with a flange, and the core is fixed to the drive shaft through the flange.

[0011] Preferably, the second support plate is provided with a second bearing seat, which rotatably supports the end of the lead screw away from the transverse motor.

[0012] Preferably, a spring, serving as a buffer element, is coaxially sleeved between the first bearing housing and the driven wheel.

[0013] Preferably, the output shaft of the transverse motor is connected to the input end of the lead screw via a coupling.

[0014] Preferably, the winding assembly is provided with a first origin sensor, and the position of the first origin sensor is set to detect the starting position of the rotation of the winding core.

[0015] Preferably, a second origin sensor is provided at one end of the guide rail of the unloading assembly, and the position of the second origin sensor is set to detect the initial position of the slider movement.

[0016] This utility model has the following beneficial effects: In this invention, by adding a material unloading assembly consisting of a transverse motor, lead screw, slider, and chuck, and linking the material unloading assembly with the drive shaft and core of the winding assembly, the problems of manual unloading, high labor intensity, and low production efficiency in the prior art after winding are solved. This achieves the effects of automatic material unloading, simplified operation process, and significant improvement in overall production efficiency.

[0017] In this invention, by using a synchronous belt for winding transmission and setting a first origin sensor for detecting the starting position of winding and a second origin sensor for locating the initial position of unwinding, the problems of inaccurate winding turns and inaccurate unwinding stroke control that may exist in traditional winding mechanisms are solved. This achieves high-precision closed-loop control of the winding and unwinding processes, thereby ensuring the consistency of product quality and the repeatability of the process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 5 This utility model provides a winding mechanism for a winding machine, which aims to solve the problems of high labor intensity, cumbersome unwinding process, and difficulty in ensuring winding and unwinding accuracy in the prior art.

[0022] like Figure 1 As shown, the winding mechanism of the winding machine includes a support assembly 1 and a winding assembly 2 disposed on the support assembly 1. The winding assembly 2 includes a winding motor 201, a drive wheel 202 and a driven wheel 204 fixedly connected to the output end of the winding motor 201, and a synchronous belt 203 wound on the drive wheel 202 and the driven wheel 204. The driven wheel 204 is fixedly connected to one end of the transmission shaft 205 to drive the transmission shaft 205 to rotate. The first bearing seat 206 provides rotational support for the transmission shaft 205. The core 207 is fixedly installed on the transmission shaft 205 and rotates synchronously with the transmission shaft 205.

[0023] Specifically, please refer to Figure 1 , Figure 3 and Figure 5 The unloading assembly 3 includes a transverse motor 301, a lead screw 303, a guide rail 306, a slider 305, and a chuck 307. The transverse motor 301 is fixedly mounted on the support assembly 1 and serves as the power source for the unloading action. The output end of the transverse motor 301 is connected to one end of the lead screw 303. The guide rail 306 is arranged parallel to the length of the lead screw 303. The slider 305 has an internal thread structure that matches the external thread of the lead screw 303, and the bottom of the slider 305 has a sliding guide groove that cooperates with the guide rail 306, allowing the slider 305 to move along the lead screw. When 303 rotates, it makes a smooth linear reciprocating motion along the guide rail 306. One end of the chuck 307 is rigidly fixed to the upper surface of the slider 305, and the other end of the chuck 307 forms a fork-shaped structure that can abut against the outer wall of the first bearing seat 206. When the slider 305 moves, the chuck 307 can stably push or pull the first bearing seat 206, thereby driving the entire transmission shaft 205 and the core 207 to move synchronously along the guide direction of the guide rail 306, realizing the automatic detachment of the rolled material from the core 207, ensuring the smoothness of the unloading process and the accuracy of the positioning.

[0024] In a preferred embodiment, to achieve modular installation and stable support of the components, please refer to... Figure 1 and Figure 2 The support assembly 1 includes a mounting base 101, a connecting plate 102 fixed on the mounting base 101, and a first support plate 103 and a second support plate 104 respectively fixedly connected to both sides of the connecting plate 102. The winding motor 201 is fixed to the first support plate 103 by bolts, while some components of the unloading assembly 3 are installed on the second support plate 104. This split support plate design facilitates the independent assembly and debugging of the two major functional modules of winding and unloading.

[0025] Furthermore, to ensure secure installation and power transmission of the core 207, please refer to... Figure 2 and Figure 4A flange 105 is fixedly installed on the mounting base 101. The drive shaft 205 passes through the center hole of the flange 105, and the core 207 is fixedly connected to the flange 105 through the connection structure at its end. Thus, when the drive shaft 205 rotates, the power can be reliably transmitted to the core 207 through the flange 105.

[0026] Furthermore, to ensure the stability of the lead screw 303's rotation, please refer to... Figure 1 A second bearing seat 304 is also fixedly installed on the second support plate 104. The second bearing seat 304 provides rotational support for the end of the lead screw 303 away from the transverse motor 301, effectively preventing radial sway that may occur when the lead screw 303 rotates at high speed.

[0027] In another preferred embodiment, to absorb the shocks and vibrations of the transmission system during start-up, shutdown, and operation, please refer to... Figure 3 A spring 209 is sleeved between the first bearing housing 206 and the driven wheel 204 along the axial direction of the transmission shaft 205. The two ends of the spring 209 abut against the end faces of the first bearing housing 206 and the driven wheel 204 respectively, which plays a good buffering role and protects the smooth operation of the transmission system.

[0028] In another preferred embodiment, to achieve precise and error-compensating power transmission between the transverse motor 301 and the lead screw 303, please refer to... Figure 1 The output shaft of the transverse motor 301 is connected to the input end of the lead screw 303 via a coupling 302.

[0029] In another preferred embodiment, for accurate counting of the winding process, please refer to... Figure 1 The winding assembly 2 is provided with a first origin sensor 208. The sensing probe of the first origin sensor 208 is directly opposite the marking point set on the winding core 207 or the drive shaft 205, so as to accurately detect the starting position of each rotation.

[0030] In another preferred embodiment, to achieve precise positioning of the material retraction stroke, please refer to... Figure 1 A second origin sensor 308 is fixedly installed near the end of the guide rail 306. The sensing probe of the second origin sensor 308 is facing the side of the slider 305 to accurately detect the initial or limit position of the slider 305.

[0031] Working principle: When the winding mechanism of the winding machine is working, firstly, the end of the strip to be wound is manually fixed to the core 207. Then, the winding assembly 2 is started, and the winding motor 201 is energized and rotates. Through the drive wheel 202 and the synchronous belt 203, the driven wheel 204 is driven to rotate. The transmission shaft 205, which is fixedly connected to the driven wheel 204, rotates accordingly, thereby driving the core 207 to rotate synchronously, thus tightly winding the strip onto the core 207. During the winding process, the first origin sensor 208 continuously detects the number of rotations of the core 207. When the preset number of rotations is reached, the control system stops the winding motor 201, and the winding process ends. Next, the unloading assembly 3 is started, and the transverse motor 301 is energized and rotated. The electric rotation transmits power to the lead screw 303 via the coupling 302. The rotation of the lead screw 303 drives the threaded slider 305 to move linearly along the guide rail 306. The pawl 307 fixed on the slider 305 simultaneously pushes the first bearing seat 206, causing the first bearing seat 206, the drive shaft 205, and the core 207 on it to retract axially as a whole. Finally, the coiled strip slides off the core 207, completing the automatic unwinding action. The second origin sensor 308 is used to detect the start or end position of the unwinding to ensure the accuracy of the unwinding stroke. After one unwinding is completed, the transverse motor 301 rotates in the opposite direction, driving the core 207 to reset, preparing for the next winding.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
