[0047] As the COVID-19 pandemic continues to spread and the number of infected people continues to rise, masks are in short supply. Therefore, various manufacturers have launched various mask machines to meet the urgent demand for masks for epidemic prevention and control.

[0048] At present, the ear wires of masks purchased by mask manufacturers are usually wrapped together in a messy way, and the ear wires are uneven, clumped or tangled. This greatly affects the efficiency of the mask machine in sewing or fusing the mask body and the ear wires. The workmanship of the mask is also poor, and it is usually necessary to arrange additional employees to manually straighten and wind the wires, which greatly increases the production cost of the mask.

[0049] In order to straighten and wind up disordered ear wires and other wires to improve the yield rate of mask production, the present invention proposes a winding device suitable for straightening and winding various wires, especially an ear wire winding machine, which is not limited here.

[0050] Reference Figures 1 to 3 In one embodiment of the present invention, the wire device includes a base 100, a wire-straightening assembly 200 and a wire-winding assembly 300. The wire-straightening assembly 200 is installed on the base 100. The wire-straightening assembly 200 includes a wire-straightening rod 210. The wire-straightening rod 210 is provided with a guide hole 211 for the externally connected ear wire 10 to pass through. The guide hole 211 is used to straighten the passing ear wire 10; the wire-winding assembly 300 is installed on the base 100 and is arranged opposite to the wire-straightening assembly 200. The wire-winding assembly 300 is used to reel in the straightened ear wire 10.

[0051] It should be noted that the base 100 can be a square steel plate or a bottom plate with support feet installed, etc. Pads can be provided on the support feet to reduce the wear between the support feet and the work surface and avoid scratching the work surface.

[0052] In this embodiment, the top of the base 100 has a mounting surface, and the wire-straightening assembly 200 can be fixed on one side of the mounting surface of the base 100 through a mounting plate, and the mounting plate and the base can be connected and fixed through a support column. The wire-straightening rod 210 can be installed on the mounting plate through bolts or screws and extend in the vertical direction. The guide hole 211 thereon can be set at one end or the middle position of the wire-straightening rod 210 away from the base 100. The specific position of the guide hole 211 is not limited here. The shape of the guide hole 211 can be set to be the same or similar to the shape of the ear wire 10, and can be a square through hole, a circular through hole or other shapes, so as to straighten the ear wire 10.

[0053] A housing can be installed on the other side of the mounting surface of the base 100 for mounting the driving components and winding components of the winding assembly 300 . The housing can be square or cylindrical, etc., which is not limited here.

[0054] It can be understood that the present invention installs the wire-winding assembly 200 of the wire-winding device on the base 100, and the wire-winding assembly 200 includes a wire-winding rod 210, and the wire-winding rod 210 is provided with a guide hole 211 for the ear wire 10 connected to the outside to pass through, and the guide hole 211 is used to straighten the ear wire 10 passing through, and the wire-winding assembly 300 is installed on the base 100 and arranged opposite to the wire-winding assembly 200, and the wire-winding assembly 300 is used to reel in the straightened ear wire 10, thereby straightening and reeling up the disordered ear wire 10, so that the ear wire 10 of the mask is smoother, thereby improving the yield rate of mask production.

[0055] In order to achieve the winding process of the straightened ear wire 10, in one embodiment, refer to Figure 1 and Figure 2 The wire winding assembly 300 may include a first driving member 310 and a wire reel 320 drivingly connected to the first driving member 310. The wire reel 320 is used to reel the straightened ear wire 10 under the driving of the driving member. The wire reel 320 is drivingly connected to the first driving member 310 via a rotating shaft. The wire reel 320 is disposed on one side of the top of the housing and is disposed opposite to the guide hole 211 of the wire reel 210.

[0056] Furthermore, in order to control the rotation speed and rotation direction of the first driving member 310 of the winding assembly 300, to prevent the ear wire 10 from being torn or winding in disorder, thereby improving the winding efficiency, in one embodiment, reference Figure 1 and Figure 2 The winding device further includes a controller (not shown in the figure, the controller can be installed inside the housing or other parts on the base) and a detection component 400. The controller is installed on the base 100 and connected to the first driving member 310; the detection component 400 is installed on the winding rod 210 and connected to the controller. The detection component 400 is used to detect the tension of the ear wire 10 or the position of the ear wire 10 and send a tension signal or a position signal to the controller. The controller is used to control the speed or direction of the first driving member 310 according to the tension signal or the position signal.

[0057] In this embodiment, the controller can be disposed in the housing and connected to the detection component 400 on the winding rod 210. The controller can be a PLC controller, etc., which is not limited here.

[0058] In one embodiment, the detection assembly 400 may include a mechanical micro switch 410, which is installed on the wire reel 210 near the guide hole 211. The mechanical micro switch 410 is used to detect the tension of the ear wire 10 at the guide hole 211. The controller is used to control the first driving member 310 to stop rotating when the tension signal is greater than a preset tension value.

[0059] Of course, in some embodiments, the controller can also compare the detected tension signal with the preset tension range value of the system to adjust the rotation speed or direction of the first driving member 310 so that the winding reel 320 can reel the ear wire 10 more orderly and prevent the ear wire 10 from being pulled and broken.

[0060] In addition, the detection component 400 can also be a position sensor, which can be installed on the wire reel 210 near the guide hole 211; the position sensor is used to detect the height position of the ear wire 10 at the guide hole 211; the controller is used to adjust the rotation speed or direction of the first drive member 310 when the position signal is not in the preset position.

[0061] Among them, the position sensor can be a photoelectric sensor. One or more photoelectric sensors can be set near the guide hole 211 of the winding rod 210 to detect the position of the ear wire 10 to determine the tightness of the ear wire 10 at this point, and then adjust the winding speed of the winding reel 320 according to the position signal.

[0062] It should be noted that a photoelectric sensor is a device that converts light signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon that when light shines on certain substances, the electrons of the substance absorb the energy of photons and produce corresponding electrical effects. According to the different photoelectric effect phenomena, the photoelectric effect is divided into three categories: external photoelectric effect, internal photoelectric effect and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, photocells, etc. The photoelectric detection method has the advantages of high precision, fast response, non-contact, etc., and it can measure many parameters. The sensor has a simple structure and flexible and diverse forms. Therefore, photoelectric sensors are widely used in detection and control.

[0063] In some application scenarios, the ear wire 10 will generate a large resistance when passing through the guide hole 211 due to being wound too tightly, and there is a situation where the ear wire 10 cannot pass through the guide hole 211. At this time, if the winding operation is continued, the ear wire 10 will be broken or the winding rod will be locally deformed by force. In order to detect the resistance of the ear wire 10 at the guide hole 211 so as to automatically shut down the winding device in time, in one embodiment of the present invention, mainly referring to Figure 5 and Figure 6There are two guide holes 211 on the wire reel 210. The two guide holes 211 are arranged at the ends of the wire reel 210. A wire reel block 212 is arranged between the two guide holes 211. The wire reel block 212 is connected to the side wall of the wire reel 210 and is used to straighten the passing ear wire 10. In this embodiment, the wire reel device also includes an alarm component 500. The alarm component 500 includes a sensor 510 connected to the controller. The sensor 510 is connected and fixed to the wire reel 210 through a bracket 501. The sensor 510 is connected to the wire reel block 212 through an elastic member 502 and is used to send an alarm signal when it is detected that the actual resistance value of the ear wire 10 is greater than or equal to the preset resistance value. After receiving the alarm signal, the controller controls the winding device to shut down.

[0064] In this embodiment, an additional mounting seat can be provided at the end of the wire straightening rod 210, and the mounting seat can be formed by enclosing a plurality of mounting plates to form a mounting cavity for mounting various components of the alarm assembly 500, and the side wall of the mounting seat can be provided with the above-mentioned two opposite guide holes 211. The surface of the wire straightening block 212 that contacts the ear wire 10 can be arranged in an arc shape to straighten the ear wire 10 passing through.

[0065] In order to achieve the smoothing of the messy ear wire 10, in one embodiment, Figure 3 and Figure 4 The wire-winding assembly 200 may further include a second driving member 220, which is drivingly connected to the wire-winding rod 210. The wire-winding rod 210 is driven by the second driving member 220 to reciprocate in a direction parallel to the axis of the wire reel 320, so as to evenly place the straightened ear wire 10 onto the wire reel 320 along the axis of the wire reel 320. The body of the second driving member 220 may be mounted on a mounting plate on one side of the base 100 by bolt connection or screw connection.

[0066] In this embodiment, the second driving member 220 may be a motor, and the motor and the wire drawing rod 210 may be driven and connected via a screw assembly 230 .

[0067] Further, in one embodiment, mainly referring to Figure 4 The screw assembly 230 may include a ball screw shaft 231, a nut 232, a slider 233 and a slide rail 234. The ball screw shaft 231 is connected to the motor drive. The nut 232 is sleeved on the ball screw shaft 231. The slider 233 is arranged on the nut 232 and is slidably connected to the slide rail 234. The slide rail 234 is arranged on the base 100 and close to both sides of the ball screw shaft. The wire reel 210 is installed on the slider 233 so that the wire reel 210 can reciprocate in a direction parallel to the axis of the winding reel 320 under the drive of the motor.

[0068] Among them, the motor can be a screw stepper motor, etc. The screw stepper motor, also known as a linear stepper motor, is generated by the interaction between the magnetic rotor core and the pulse electromagnetic field generated by the stator to generate rotation. The screw stepper motor converts the rotational motion into linear motion inside the motor.

[0069] The present invention also proposes a mask machine, which includes a wire winding device. The specific structure of the wire winding device refers to the above-mentioned embodiment. Since the mask machine proposed by the present invention includes all schemes of all embodiments of the above-mentioned wire winding device, it has at least the same technical effect as the wire winding device, which will not be elaborated here one by one.
