Description

Technical Field

[0001] This application relates to the technical field of waste edge winding, and in particular to a self-starting and stopping waste edge winding device. Background Technology

[0002] In industrial production processes, such as sheet metal cutting, film production, or textiles, a large amount of strip-shaped waste material is generated. To facilitate recycling, transportation, and reuse, these waste materials are usually wound into coils using reels.

[0003] In related technologies, the winding length of a winding reel is controlled by a preset time, and the winding automatically stops after the predetermined time is reached. However, this method cannot precisely control the actual amount of wire wound onto the reel, which may lead to resource waste or underutilization of storage capacity. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a self-starting and stopping device for winding waste edge discs.

[0005] The self-starting and stopping waste edge winding device provided in this application adopts the following technical solution: A self-starting and stopping waste edge winding device, comprising:

[0006] abutment;

[0008] A drive mechanism for driving the winding disc to rotate;

[0009] A limit sensing component is mounted on the base. The limit sensing component includes a limit rod and a trigger switch that is driven by the limit rod. The end of the limit rod points to the winding reel. When the winding diameter of the waste edge reaches a preset value, the outer edge of the waste edge abuts against and pushes the limit rod to rotate, so that the limit rod triggers the trigger switch to generate a stop signal that is transmitted to the drive mechanism.

[0010] The limit sensing component is connected to an adjustment component, which is used to move the trigger switch in a direction perpendicular to the base, thereby changing the distance between the end of the limit rod and the center of the winding reel.

[0011] By adopting the above technical solution, the base provides an installation foundation for the winding disc, drive mechanism and limit sensing component. The drive mechanism drives the winding disc to rotate to realize waste edge winding. The limit sensing component can trigger the trigger switch to generate a stop signal to stop the drive mechanism when the waste edge winding diameter reaches the preset value, so as to avoid excessive winding of the waste edge. The adjustment component can move the trigger switch in a direction perpendicular to the base to change the distance between the end of the limit rod and the axis of the winding disc, thereby adjusting the preset value of the waste edge winding diameter.

[0012] Preferably, a first support seat and a second support seat are installed on the base and arranged parallel to the first support seat at a distance. The top surface of the first support seat away from the base has an arc-shaped groove, and the second support seat has a circular shaft hole at a distance away from the base. The two ends of the rotating shaft of the winding reel are respectively mounted in the arc-shaped groove and pass through the circular shaft hole and are connected to the driving mechanism for transmission.

[0013] By adopting the above technical solution, a first support seat and a second support seat are set on the base. The first support seat is provided with an arc-shaped groove, and the second support seat is provided with a circular shaft hole. The two ends of the winding disc shaft are respectively mounted on the arc-shaped groove and pass through the circular shaft hole and are connected to the drive mechanism for transmission. This can stably support the winding disc, ensure the stability of the winding disc rotation process, and enable the winding disc to rotate smoothly for waste edge winding.

[0014] Preferably, the winding reel includes two parallel side plates spaced apart, with the side plate closer to the first support forming an installation gap with the first support.

[0015] By adopting the above technical solution, based on the setting of the winding disc, drive mechanism, limit sensing component and adjustment component on the base, the two side discs of the winding disc form an installation gap with the first support base, which facilitates the installation and maintenance of the winding disc.

The connecting seat is mounted on the second support seat, the threaded rod is fixedly mounted on the connecting seat and is arranged perpendicular to the central axis of the second connecting seat, and the adjusting nut is threadedly connected to the trigger switch on the threaded rod. The adjusting nut is located at the lower end of the trigger switch near the connecting seat.

[0017] By adopting the above technical solution, the base provides support for the device, the winding disc can rotate under the drive mechanism to wind the waste edge, and the limit sensing component can trigger the trigger switch to generate a stop signal to stop the drive mechanism when the waste edge winding diameter reaches the preset value; the adjustment component includes a connecting seat, a threaded rod and an adjusting nut. The connecting seat is installed on the second support seat, the threaded rod is set perpendicular to the central axis of the second connecting seat, and the adjusting nut is threadedly connected to the trigger switch on the threaded rod and located near the lower end of the connecting seat, which can realize the movement of the trigger switch in a direction perpendicular to the base, thereby changing the distance between the end of the limit rod and the axis of the winding disc to adjust the preset diameter of the waste edge winding.

[0018] Preferably, it also includes a reciprocating wiring mechanism for guiding the waste edge to be wound evenly, the reciprocating wiring mechanism being fixedly mounted on the base and located on the path of the waste edge entering the winding reel.

[0019] By adopting the above technical solution, the base, winding disc, drive mechanism, limit sensor component and adjustment component constitute a self-starting and stopping waste edge winding disc device, which can automatically stop when the waste edge winding diameter reaches the preset value, and can adjust the position of the trigger switch to change the distance between the end of the limit rod and the center of the winding disc; the reciprocating wiring mechanism can guide the waste edge to wind evenly.

[0020] Preferably, the reciprocating wiring mechanism includes a mounting base fixedly mounted on the base, a reciprocating lead screw mounted on the mounting base and arranged parallel to the rotating shaft of the winding reel, a drive motor for driving the reciprocating lead screw to rotate, and a movable seat threaded on the reciprocating lead screw. The movable seat is fixedly mounted with a wire block, and the wire block is provided with a guide hole for the waste edge to pass through.

[0021] By adopting the above technical solution, a reciprocating wiring mechanism is installed on the base. The reciprocating screw is driven to rotate by the drive motor, and the moving seat with the thread sleeve on the reciprocating screw drives the wire block to move. The waste edge passes through the guide hole of the wire block, so that the waste edge is evenly wound on the winding spool.

[0022] Preferably, a guide roller is rotatably connected inside the guide hole, and a plurality of spaced limiting pieces are installed on the guide roller along the axial direction. The inner wall of the guide hole is provided with a groove that matches the limiting pieces.

[0023] By adopting the above technical solution, a rotating guide roller is set in the guide hole, which can reduce the friction when the waste edge passes through the guide hole, making the waste edge move more smoothly; the limiting pieces set at intervals on the guide roller cooperate with the grooves on the inner wall of the guide hole, which can limit the waste edge, prevent the waste edge from shaking or deviating in the guide hole, and ensure that the waste edge is evenly wound on the winding spool.

[0024] Preferably, the mounting base is further equipped with a guide rod, which is arranged parallel to the axis of rotation of the winding reel. The movable base has a guide hole, through which the guide rod passes.

[0025] By adopting the above technical solution, the guide rod and the guide hole of the moving seat cooperate to guide the movement of the moving seat when the reciprocating wiring mechanism is working, so that the wire block drives the waste edge to move back and forth more stably, ensuring that the waste edge is evenly wound on the winding spool.

[0026] Preferably, the drive mechanism includes a rotary motor and a coupling. The rotary motor is mounted on the base, and the shaft of the winding reel near the second support is connected to the rotary motor via the coupling.

[0027] By adopting the above technical solution, the rotating motor provides power for the rotation of the winding disc, and the coupling connects the rotating motor and the shaft of the winding disc to realize power transmission, so that the winding disc can rotate under the drive of the rotating motor to wind waste edge wire.

[0028] Preferably, the system further includes a controller electrically connected to the rotating motor and communicatively connected to the trigger switch, wherein the trigger switch sends a stop signal to the controller, and the controller controls the drive motor to stop rotating by power-off.

[0029] By adopting the above technical solution, the self-starting and stopping waste edge winding device can achieve automated control. When the waste edge winding diameter reaches the preset value, the limit rod triggers the trigger switch to generate a stop signal. The controller controls the drive motor to cut off power and stop rotating, so that the device can automatically stop running and avoid excessive winding of the waste edge.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The reciprocating wiring mechanism guides the waste edge to be evenly wound on the winding spool, avoiding waste edge accumulation and uneven winding, thus improving the winding effect;

[0032] 2. The limit sensor component can sense the winding diameter of the waste edge on the winding disc. When the preset value is reached, it controls the drive mechanism to stop driving the winding disc to rotate, realizing the self-start and stop function, avoiding over- or under-winding, providing convenience for subsequent waste recycling and improving resource utilization.

[0038] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0039] refer to Figure 1 This application provides a self-starting and stopping waste edge winding device, including a base 1, a winding disc 2, a drive mechanism 3, a limit sensing component 4, and an adjustment component 5. The winding disc 2 is mounted on the base 1, the drive mechanism 3 drives the winding disc 2 to rotate, the limit sensing component 4 is mounted on the base 1, and the adjustment component 5 is connected to the limit sensing component 4. This achieves the beneficial effect of automatically starting and stopping the winding disc 2 according to the waste edge winding diameter, and flexibly adjusting the trigger position. This is because when the waste edge is wound to a preset diameter, the limit sensing component 4 can trigger a switch 42 to stop the drive mechanism 3, and the adjustment component 5 can change the position of the trigger switch 42 to adapt to different needs.

[0040] Specifically, the base 1 serves as the fundamental support component of the entire device, bearing the weight of other components. It can be made of metallic materials, such as steel, which possesses high strength and stability to ensure the device does not shake or shift during operation. Alternatively, other materials such as high-strength plastics can be used to manufacture the base 1 to meet different usage scenarios and cost requirements.

[0041] refer to Figures 1-3The base 1 provides a stable mounting foundation for the entire device. In this embodiment, a first support 11 and a second support 12 are arranged parallel to each other at intervals on the base 1. The top surface of the first support 11 has an arc-shaped groove 111 for supporting one end of the winding reel 2's shaft. This design simplifies installation, allowing the winding reel 2 to be easily placed and removed. The second support 12 has a circular shaft hole 121 for the other end of the winding reel 2's shaft to pass through and connect with the drive mechanism 3, ensuring the stability of the transmission.

[0042] refer to Figures 1-2 The winding reel 2 is mounted on the base 1 and is used to wind waste material. It includes two parallel side discs 21 spaced apart, with the side disc 21 closer to the first support 11 forming an installation gap 22 with the first support 11. The installation gap 22 facilitates the installation and removal of the winding reel 2. The winding reel 2 can be made of lightweight metal materials such as aluminum alloy, which ensures its strength while reducing the overall weight and the load on the drive mechanism 3. The side discs 21 of the winding reel 2 can be circular, and their edges can be chamfered to prevent scratching the waste material when winding it.

[0043] The drive mechanism 3 drives the winding reel 2 to rotate. It includes a rotary motor 31 and a coupling 32. The rotary motor 31 is mounted on the base 1. The shaft of the winding reel 2 near the second support 12 is connected to the rotary motor 31 via the coupling 32. The rotary motor 31 can be an AC motor, which has advantages such as a wide speed range and stable operation. The coupling 32 can be a flexible coupling, which can buffer the impact and vibration during rotation, protecting the motor and the shaft of the winding reel 2.

[0044] refer to Figure 1 and Figure 3 The limit sensing component 4 is mounted on the base 1. It includes a limit rod 41 and a trigger switch 42 that is pulsatorically connected to the limit rod 41. The end of the limit rod 41 points towards the winding reel 2. When the winding diameter of the waste edge reaches a preset value, the outer edge of the waste edge abuts against and pushes the limit rod 41 to rotate, so that the limit rod 41 triggers the trigger switch 42 to generate a stop signal that is transmitted to the drive mechanism 3. The limit rod 41 can be made of stainless steel, which has good corrosion resistance. The limit rod 41 can be rod-shaped, and its end can be rounded to reduce friction with the waste edge. The trigger switch 42 can be a mechanical micro switch, which has the characteristics of high sensitivity and reliable operation. In this embodiment, the limit rod 41 rotates about a pivot at one end, and the middle part of its rod or the other end directly abuts against and presses the contact of the trigger switch 42. When the outer edge of the waste edge pushes the end of the limit rod 41, the limit rod 41 rotates at a small angle, which is sufficient to trigger the switch 42 at the other end.

[0045] refer to Figure 1 and Figure 3 An adjusting assembly 5 is connected to the base 1, which moves the trigger switch 42 in a direction perpendicular to the base 1, thereby changing the distance between the end of the limiting rod 41 and the axis of the winding reel 2. The adjusting assembly 5 includes a connecting seat 51, a threaded rod 52, and an adjusting nut 53. The connecting seat 51 is mounted on the second support base 12. The threaded rod 52 is fixedly mounted on the connecting seat 51 and is perpendicular to the central axis of the second connecting seat 51. The adjusting nut 53 is threadedly connected to the trigger switch 42 on the threaded rod 52, and is located at the lower end of the trigger switch 42 near the connecting seat 51. By rotating the adjusting nut 53, the trigger switch 42 can move up and down along the threaded rod 52, thereby changing the initial position of the limiting rod 41 to adapt to different waste edge winding requirements.

[0046] refer to Figure 2 To further improve winding quality, a reciprocating wiring mechanism 6 is added. This mechanism guides the waste edge back and forth in the width direction of the winding reel 2, thereby achieving a uniform and neat arrangement. The reciprocating wiring mechanism 6 is fixedly mounted on the base 1, located on the path where the waste edge enters the winding reel 2. It mainly includes a mounting base 61, a reciprocating lead screw 62, a drive motor 63 for the reciprocating lead screw 62, and a movable seat 64 threaded onto the reciprocating lead screw 62. The mounting base 61 provides a mounting base for other components of the reciprocating wiring mechanism 6. The reciprocating lead screw 62 is mounted parallel to the shaft of the winding reel 2, and its two ends are rotatably supported on the mounting base 61 by bearing seats. The output shaft of the drive motor 63 (e.g., a stepper motor or a servo motor) is connected to one end of the reciprocating lead screw 62 via a coupling 32.

[0047] refer to Figure 2 A wire block 65 is fixedly mounted on the movable base 64. The wire block 65 has a wire hole 651 for the waste edge to pass through. When the drive motor 63 drives the reciprocating screw 62 to rotate in the forward or reverse direction, the movable base 64 will move left and right along the reciprocating screw 62, thereby causing the wire block 65 and the waste edge passing through it to reciprocate across the entire width of the winding reel 2. To ensure the stability of the movable base 64 during movement and prevent it from rotating around the reciprocating screw 62, a guide rod 67 is also mounted on the mounting base 61 parallel to the reciprocating screw 62. The movable base 64 has a corresponding guide hole 641 that slides with the guide rod 67.

[0048] refer to Figure 4 To better guide the waste edge and prevent it from bouncing within the wire hole 651, a guide roller 66 is rotatably mounted within the wire hole 651. The surface of the guide roller 66 may be provided with multiple spaced limiting pieces 661 along the axial direction, while a matching groove 652 is provided on the inner wall of the wire hole 651. The waste edge passes between two limiting pieces 661, achieving a better guiding effect.

[0049] refer to Figure 1 and Figure 2 This embodiment also includes a controller 7 electrically connected to the rotating motor 31 and communicatively connected to the trigger switch 42. The trigger switch 42 sends a stop signal to the controller 7, and the controller 7 controls the drive motor 63 to stop rotating. The drive motor 63 of the reciprocating wiring mechanism 6 is also controlled by the controller 7. The controller 7 can achieve precise and uniform arrangement of waste edges according to the rotation speed of the winding reel 2 and the width of the waste edge. The controller 7 can be a single-chip microcomputer, which has the advantages of small size, low cost, and flexible control. More specifically, the controller 7 can achieve precise control of the rotating motor 31, improving the automation level of the device. More specifically, the controller 7 has a built-in control program that controls the drive motor 63 of the reciprocating wiring mechanism 6 to rotate forward and backward at a set speed according to the preset width of the winding reel 2 and the width of the waste edge, so that the reciprocating stroke of the moving seat 64 matches the inner width of the winding reel 2. At the same time, the controller 7 can correlate the rotation speed of the rotating motor 31 with the moving speed of the drive motor 63 to ensure that the waste edge is always evenly and tightly arranged at different winding speeds.

[0050] The implementation principle of the self-starting and stopping waste edge winding device in this application embodiment is as follows: First, the operator rotates the adjusting nut 53 to set the stopping winding diameter according to the winding requirements. Then, the waste edge end from the production line is passed through the wire hole 651 of the reciprocating wiring mechanism 6 and fixed on the core of the winding reel 2. The device is started, and the controller 7 controls the rotating motor 31 to start rotating, driving the winding reel 2 to wind the waste edge; at the same time, the controller 7 controls the drive motor 63 of the reciprocating wiring mechanism 6 to work, causing the wire block 65 to move back and forth, guiding the waste edge to be evenly distributed. During the winding process, as the winding diameter of the waste edge increases, when its outer edge finally pushes the limit rod 41 to trigger the trigger switch 42, the controller 7 receives the stop signal and immediately stops the operation of the rotating motor 31 and the drive motor 63, and the winding process ends automatically. The operator removes the fully wound winding reel 2, replaces it with an empty reel, and can start the next round of automatic winding.

[0051] In summary, in the field of automation control, when precise position or size sensing is required, the conventional approach for those skilled in the art is to use electrical signal sensors (such as photoelectric, infrared, ultrasonic, and laser sensors). This application, however, takes a different approach, employing a purely mechanical direct contact sensing scheme. This application directly drives the trigger switch through the physical displacement of a limit rod. This energy transfer path of "physical quantity → mechanical displacement → switch on / off" is extremely short, with almost no intermediate steps. Compared to the electronic scheme of "physical quantity → electrical signal → signal processing → A / D conversion → controller logic judgment → output command," this application's scheme fundamentally avoids problems such as electrical signal interference, sensor drift, and complex circuit failures, exhibiting extremely high stability and environmental adaptability.

[0052] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
