Description

Technical Field

[0001] The present application relates to the field of winding equipment, and in particular to a tension mechanism of a flat wire rectangular closed core winding machine. Background Art

[0002] Winding machine is a device that winds linear objects onto specific workpieces, usually used for copper wire winding. Most electrical products need to be wound into inductor coils with enameled copper wire (enameled wire for short), and winding machines can be used to complete this one or more processes. For example: various motors, hollow cup motors, rotors, stators, pin inductors, chip inductors, transformers, solenoid valves, one-word inductors, resistors, ignition coils, RFID, mutual inductors, audio coils, IC card high and low frequency coils, focusing coils, etc. The textile industry uses cotton yarn, man-made fiber wire, etc. to wind various yarn balls and yarns suitable for textile machines, which can also be processed using winding machines. The wires commonly wound by winding machines are mostly enameled copper wire (winding inductor coils for electronic and electrical products), enameled aluminum wire, textile wire (winding spindles and coils for textile machines), as well as heating wires for electric heating appliances, solder wires, wires, cables, etc. There are many types of winding machines, which can be divided into general-purpose and special-purpose types according to their uses; general-purpose winding machines are suitable for a variety of products. Just replace the corresponding molds and instructions to correspond to the processing of different products. Special-purpose winding machines are designed for a specific product.

[0003] The tension mechanism of the existing flat wire rectangular closed core winding machine uses two motors, each motor drives a flat wire drum to be wound; several wire wheels are installed vertically on both sides, and several are installed horizontally on each side near the winding wire entry position. The disadvantage is that the two motors drive the rotation speed, which is difficult to synchronize, and the tension of the two wires wound around the magnetic core is inconsistent, so two matching tension control mechanisms are required. At the same time, the existing tension control mechanism can only roughly adjust the copper wire, and cannot achieve the purpose of finely adjusting the tension of the copper wire. Utility Model Content

[0004] In order to solve the problem that the existing fertilizing device cannot fertilize deeply, the present application provides a tension mechanism of a flat wire rectangular closed magnetic core winding machine.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] A tension mechanism of a flat wire rectangular closed core winding machine comprises a fixing mechanism, a limiting mechanism, an adjusting mechanism, and an enameled copper wire. The fixing mechanism comprises a fixing frame, the limiting mechanism comprises four groups of limiting disk groups, and the four groups of limiting disk groups are rotatably connected to four groups of vertical poles of the fixing frame respectively. The enameled copper wire passes through the limiting disk groups on the same side. The adjusting mechanism comprises a first driving mechanism, a second driving mechanism, a rotating shaft, a pair of connecting rods, and a pair of eccentric wheels. The rotating shaft is rotatably installed on the top of the fixing frame. The first driving mechanism drives the rotating shaft to rotate, and the pair of connecting rods are installed on the outside of the rotating shaft. A slot is opened at the bottom end of the connecting rod, and the eccentric wheel is rotatably installed in the slot. The second driving mechanism drives the eccentric wheel to rotate.

[0007] By adopting the above scheme, the first driving mechanism is used to drive the rotating shaft to rotate, thereby driving a pair of connecting rods on its outer side to rotate, so that a pair of eccentric wheels squeeze a pair of enameled copper wires at the same time, so as to achieve the purpose of roughly adjusting the tension of the enameled copper wires, and the second driving mechanism is used to drive the eccentric wheel to rotate, so that the eccentric wheel can finely adjust the tension of the enameled copper wire. At the same time, the pair of eccentric wheels are independently controlled, so they can independently adjust the tension of the corresponding enameled copper wires, so that the tension of a pair of enameled copper wires is not affected by the corresponding motors, so that their tensions can meet the winding requirements.

[0008] Specifically, the first motor and the second motor are both equipped with a reducer.

[0009] The first driving mechanism includes a first motor, which is installed on the outer side of the fixing frame through a first base, and the first motor drives the rotating shaft to rotate.

[0010] The first driving mechanism also includes a worm and a worm wheel. The output end of the first motor is drivingly connected to the worm. One end of the rotating shaft passes through the fixing frame and is connected to the worm wheel. The worm and the worm wheel are meshingly connected.

[0011] By adopting the above scheme, under the action of the worm wheel and the worm, the first motor can drive the shaft to rotate, thereby driving a pair of connecting rods to rotate. At this time, the pressure of the eccentric wheel on the enameled copper wire will change, thereby changing the tension of the enameled copper wire. At the same time, the transmission method of the worm wheel and the worm has a self-locking ability, and when the first motor stops, it can also keep the connecting rod in place.

[0012] The second driving mechanism comprises a second motor, which is mounted on the outside of the connecting rod via a second base, and the output end of the second motor is drivingly connected to the eccentric wheel.

[0013] By adopting the above solution, the eccentric wheel can rotate as the second motor is started. Since the rotation of the eccentric wheel changes the length of the extended slot, the pressure of the eccentric wheel on the enameled copper wire can be changed again, thereby changing the tension of the enameled copper wire again.

[0014] The limiting plate group includes a first limiting plate and a second limiting plate. A connecting shaft is connected between the first limiting plate and the second limiting plate and the vertical rod of the fixing frame. The side surfaces of the first limiting plate and the second limiting plate are in contact with each other.

[0015] The side surfaces of the first limiting plate and the second limiting plate are both provided with limiting grooves, and the enameled copper wire passes through the first limiting plate and the second limiting plate and is located in the limiting grooves.

[0016] By adopting the above solution, the position and movement of the enameled copper wire can be limited so that it can be squeezed by the eccentric wheel and at the same time it can be wound onto the winding mechanism.

[0017] All of the first limiting plates and the second limiting plates are installed in a vertical direction.

[0018] Four groups of fixing blocks are installed on the outer side of the fixing frame, and through holes are opened on the tops of the four groups of fixing blocks.

[0019] By adopting the above solution, the device can be fixed at a specified position by bolts, so that it will not shake or deviate during operation.

[0020] In summary, this application has the following technical effects:

[0021] The technical solution utilizes a first driving mechanism to drive the rotating shaft to rotate, thereby driving a pair of connecting rods on its outer side to rotate, so that a pair of eccentric wheels squeeze a pair of enameled copper wires at the same time, so as to achieve the purpose of roughly adjusting the tension of the enameled copper wires, and utilizes a second driving mechanism to drive the eccentric wheel to rotate, so that the eccentric wheel can finely adjust the tension of the enameled copper wires. At the same time, a pair of eccentric wheels are independently controlled, so they can independently adjust the tension of the corresponding enameled copper wires, so that the tension of a pair of enameled copper wires is not affected by the corresponding motors, so that their tensions can meet the winding requirements.

DETAILED DESCRIPTION

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] Embodiment 1

[0029] Reference Figure 1-4 , including a fixing mechanism 100, a limiting mechanism 200, an adjusting mechanism 300, and an enameled copper wire, wherein the fixing mechanism 100 includes a fixing frame 1001, the limiting mechanism 200 includes four groups of limiting disk groups, and the four groups of limiting disk groups are rotatably connected to four groups of vertical poles of the fixing frame 1001, and the enameled copper wire passes through the limiting disk groups on the same side, and the adjusting mechanism 300 includes a first driving mechanism, a second driving mechanism, a rotating shaft 3001, a pair of connecting rods 3002, and a pair of eccentric wheels 3007, The rotating shaft 3001 is rotatably mounted on the top of the fixed frame 1001, the first driving mechanism drives the rotating shaft 3001 to rotate, a pair of connecting rods 3002 are mounted on the outside of the rotating shaft 3001, the bottom end of the connecting rod 3002 is provided with a slot 3006, the eccentric wheel 3007 is rotatably mounted in the slot 3006, the second driving mechanism drives the eccentric wheel 3007 to rotate, the first driving mechanism includes a first motor 3003, the first motor 3003 is mounted on the fixed frame 1001 through the first base 001, the first motor 3003 drives the rotating shaft 3001 to rotate, and the second driving mechanism includes a second motor 3008. The second motor 3008 is installed on the outside of the connecting rod 3002 through the second base. The output end of the second motor 3008 is connected to the eccentric wheel 3007 for transmission, and the enameled copper wire passes through the limit plate group. At this time, it is located below the eccentric wheel 3007. Under the action of the worm wheel 3005 and the worm 3004, the first motor 3003 can drive the rotating shaft 3001 to rotate, thereby driving a pair of connecting rods 3002 to rotate. At this time, the pressure of the eccentric wheel 3007 on the enameled copper wire will change, thereby roughly changing the tension of the enameled copper wire. At the same time, the eccentric wheel 3007 can rotate with the start of the second motor 3008. Because the rotation of the eccentric wheel 3007 will change the length of the extended slot 3006, the pressure of the eccentric wheel 3007 on the enameled copper wire can be changed again, thereby slightly changing the tension of the enameled copper wire.

[0030] Embodiment 2

[0031] Reference Figure 1-4 , including a fixing mechanism 100, a limiting mechanism 200, an adjusting mechanism 300, and an enameled copper wire. The fixing mechanism 100 includes a fixing frame 1001. The limiting mechanism 200 includes four groups of limiting disk groups, which are rotatably connected to four groups of vertical poles of the fixing frame 1001 respectively. The enameled copper wire passes through the limiting disk groups on the same side. The adjusting mechanism 300 includes a first driving mechanism, a second driving mechanism, a rotating shaft 3001, a pair of connecting rods 3002, and a pair of eccentric wheels 3007. The rotating shaft 3001 is rotatably installed on the top of the fixing frame 1001. The first driving mechanism drives the rotating shaft 3001 rotates, a pair of connecting rods 3002 are installed on the outside of the rotating shaft 3001, a slot 3006 is opened at the bottom end of the connecting rod 3002, an eccentric wheel 3007 is rotatably installed in the slot 3006, and a second driving mechanism drives the eccentric wheel 3007 to rotate. The first driving mechanism includes a first motor 3003, and the first motor 3003 is installed on the outside of the fixing frame 1001 through a first base. The first motor 3003 drives the rotating shaft 3001 to rotate, and the second driving mechanism includes a second motor 3008, and the second motor 3008 is installed on the connecting rod 3001 through a second base. 02, the output end of the second motor 3008 is connected to the eccentric wheel 3007 for transmission, and a pair of enameled copper wires are passed through a pair of limit plate groups on the same side. Under the action of the worm wheel 3005 and the worm 3004, the first motor 3003 can drive the rotating shaft 3001 to rotate, thereby driving a pair of connecting rods 3002 to rotate. At this time, the pressure of the eccentric wheel 3007 on the enameled copper wires will change, and the tension of the pair of enameled copper wires can be changed at the same time. Because the pair of enameled copper wires are wound by a pair of motors, they are affected by the difficulty in synchronizing the rotation speeds of the pair of motors. The tension of a pair of enameled copper wires will be slightly different at the same time, because the eccentric wheel 3007 can rotate with the start-up of the second motor 3008. The rotation of the eccentric wheel 3007 will change the length of the extended slot 3006, and thus the pressure of the eccentric wheel 3007 on the enameled copper wire can be changed again. Moreover, a pair of eccentric wheels 3007 are independently controlled by a pair of second motors 3008, so the tension of a pair of enameled copper wires can be independently controlled, so that the tension of a pair of enameled copper wires can be consistent, thereby eliminating the influence of the different rotation speeds of a pair of motors on the tension of the enameled copper wires.

[0032] Embodiment 3

[0033] Reference Figure 1The limiting plate group includes a first limiting plate 2001 and a second limiting plate 2002. The first limiting plate 2001 and the second limiting plate 2002 are both connected to the vertical pole of the fixed frame 1001 with a connecting shaft 2003. The side surfaces of the first limiting plate 2001 and the second limiting plate 2002 are in contact with each other. The side surfaces of the first limiting plate 2001 and the second limiting plate 2002 are both provided with limiting grooves. The enameled copper wire passes through the first limiting plate 2001 and the second limiting plate 2002 and is located in the limiting groove, which can limit the position and movement of the enameled copper wire so that it can be squeezed by the eccentric wheel 3007 and at the same time ensure that it can be wound onto the winding mechanism.

[0034] Specifically, the unwinding mechanism and the winding mechanism are placed on both sides of the device, the enameled copper wire is wound on the unwinding device, one end of the enameled copper wire is pulled out and passed between the first limit plate 2001 and the second limit plate 2002, and the enameled copper wire is placed in the limit groove. The enameled copper wire passing between the first limit plate 2001 and the second limit plate 2002 is fixed on the winding mechanism, and the tension of the enameled copper wire is monitored in real time by a tension meter. At the same time, the first motor 3003 is started so that the deflection wheel 3007 squeezes the enameled copper wire to change its tension, and the tension meter is used to monitor the changed tension. After its value approaches the target value, the first motor 3003 is turned off, and the second motor 3008 is started to drive the eccentric wheel 3007 to rotate to change the tension of the enameled copper wire again until it is consistent with the target value. At this time, the enameled copper wire is wound by the winding mechanism. During the winding process, if the tension changes, the second motor 3008 is started again to change the tension of the enameled copper wire.
