[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example
[0030] Reference Figure 1 and Figure 2 As shown, in one embodiment of this utility model, a flexible connection drive device for a winding motor is disclosed, comprising:
[0031] The frame 1 is movably connected to the base 2;
[0032] A winding motor is connected to the base 2;
[0033] A speed reducer is connected to the frame 1. The input shaft 4 of the speed reducer is parallel to and spaced apart from the output shaft 3 of the winding motor. The input shaft 4 and the output shaft 3 are driven by a belt 5.
[0034] A locking assembly is disposed on the frame 1, which locks the base 2 and the winding motor onto the frame 1.
[0035] In the flexible connection drive device described in this embodiment, the input shaft 4 of the reducer and the output shaft 3 of the winding motor are driven by a belt 5. The belt 5 can significantly absorb and isolate the vibration transmission between the winding motor and the reducer, thereby reducing the wear and breakage of the output shaft 3 and the input shaft 4, as well as the risk of oil leakage from the reducer. The winding motor and the base 2 are pressed onto the frame 1 by the locking assembly, which makes the vibration suppression of the winding motor more significant and the operating speed more prominent. The input shaft 4 and the output shaft 3 are arranged in parallel, and the tension of the belt 5 can be flexibly adjusted by moving the center distance between the input shaft 4 and the output shaft 3.
[0036] Reference Figure 1As shown, in one embodiment of this utility model, the base 2 is a metal plate, and the base 2 is slidably connected to the frame 1 along the moving direction of the belt 5 so as to adjust the center distance between the output shaft 3 and the input shaft 4; the belt 5 is preferably a synchronous belt, and the winding motor is preferably a servo motor.
[0037] Reference Figure 1 As shown, in one embodiment of this utility model, a flexible connecting component is further included. The flexible connecting component includes a synchronous belt and a first synchronous pulley 51 and a second synchronous pulley 52 that mesh with the synchronous belt. The first synchronous pulley 51 is coaxially connected to the output shaft 3, and the second synchronous pulley 52 is coaxially connected to the input shaft 4. When the winding motor drives the output shaft 3 to rotate, the output shaft 3 drives the first synchronous pulley 51 to rotate, the first synchronous pulley 51 drives the synchronous belt to drive the synchronous belt to rotate, the synchronous belt drives the second synchronous pulley 52 to rotate, and the second synchronous pulley 52 drives the output shaft of the reducer to rotate.
[0038] Reference Figure 1 As shown, in one embodiment of this utility model, the input shaft 4 and the output shaft 3 are distributed in the horizontal direction, and the base 2 is movably connected to the frame 1 in the horizontal direction. Therefore, the center distance between the input shaft 4 and the output shaft 3 can be changed by horizontally pushing the base 2. This solution makes it easy to adjust the position of the base 2. In another embodiment, the input shaft 4 and the output shaft 3 are arranged vertically, and the base 2 is movably connected to the frame 1 in the vertical direction. This solution makes the flexible connection drive device more compact and three-dimensional, and occupies less space.
[0039] Reference Figure 1 As shown, in one embodiment of this utility model, the frame 1 is provided with a plurality of first threaded holes, and the base 2 is provided with a plurality of first strip holes 22. The fastener 21 passes through the first strip hole 22 and is threaded to the first threaded hole, so that the base 2 is fixed on the frame 1. After the fastener 21 is loosened, the first strip hole 22 facilitates the movement of the base 2.
[0040] Reference Figure 1 As shown, in one embodiment of this utility model, the locking assembly includes a plurality of locking seats distributed on both sides of the base 2. The locking seats abut against the surface of the base 2 to reduce the vibration of the base 2. The locking seats are provided with a second strip hole 612 extending along the moving direction. The fastener passes through the second strip hole 612 and is threaded to the first threaded hole to lock and fix it on the frame 1. After the fastener is loosened, the second strip hole 612 facilitates the movement of the locking seat along the moving direction.
[0041] Reference Figure 1As shown, in one embodiment of this utility model, the multiple locking seats include a first locking seat 6a and a second locking seat 6b. The first locking seat 6a and the second locking seat 6b can lock the base 2 from both sides respectively, thereby improving the locking effect of the base 2 and counteracting the vibration on both sides of the base 2.
[0042] Reference Figure 1 As shown, in one embodiment of this utility model, a plurality of locking seats are distributed on both sides of the base 2 along the moving direction of the base 2, thereby realizing bidirectional vibration suppression and high-precision positioning of the base 2.
[0043] Reference Figure 2 and Figure 3 As shown, in one embodiment of this utility model, the locking seat is provided with a second threaded hole 621 extending along the moving direction of the base 2. The fastener 63 is threadedly connected to the second threaded hole 621 and its end abuts against the side of the base 2. By rotating the fastener 63, a clamping force is generated to press the base 2 and the winding motor together, reducing the vibration when the winding motor rotates at high speed and accurately adjusting the position of the base 2. In another embodiment, the locking seat is provided with a first inclined surface. When the locking seat gradually approaches the base 2, the first inclined surface gradually abuts against the surface of the base 2, so that the base 2 and the winding motor are pressed together in both vertical and horizontal directions. The above two schemes provide two locking methods. The fastener 63 has the advantage of a relatively large adjustment range, while the first inclined surface has the advantage of better clamping stability.
[0044] Reference Figure 1 As shown, in one embodiment of the present invention, the base 2 is provided with a second inclined surface 92 on both sides that matches the first inclined surface. When the locking seat gradually approaches the base 2, the first inclined surface gradually contacts and slides along the second inclined surface 92, so that the locking block is fully fitted with both sides of the base 2.
[0045] Reference Figure 1 As shown, in one embodiment of the present invention, a support 9 that can be detachably connected to the base 2 is also included. The winding motor is fixedly connected to the support 9 through the motor connection hole 91, and the end of the fastener 63 abuts against the support 9.
[0046] Reference Figure 2As shown, in one embodiment of this utility model, the locking seat is formed by connecting a base plate 61 and a vertical plate 62. The base plate 61 is provided with a base plate connecting hole 611. The locking seat is fixed on the frame 1 by threading a screw through the base plate connecting hole 611 and threading it through the first threaded hole. The vertical plate 62 is provided with a second threaded hole 621. When assembling the drive device, the locking method of pressing the base 2 with a fastener 63 can be selected. Specifically, the base plate 61 is fixed on the frame 1 with a fastener, and then the fastener 63 is connected to the vertical plate 62. The base 2 is locked by adjusting the pressing force by rotating the fastener 63.
[0047] Reference Figure 3 As shown, in one embodiment of this utility model, the locking seat is formed by connecting a base plate 61 and a wedge block 64. The base plate 61 is provided with the second strip hole 612, and the wedge block 64 is provided with the first inclined surface. When assembling the driving device, the locking method of pressing the base 2 with the wedge block 64 can be selected. Specifically, after the wedge block 64 presses the base 2 with the first inclined surface, the base 2 is locked. Then, the base plate 61 is fixed on the frame 1 with fasteners to achieve the locking of the locking seat.
[0048] Reference Figure 4 As shown, in one embodiment of this utility model, the locking seat is composed of a base plate 61, a vertical plate 62, and a wedge block 64. The vertical plate 62 is connected to the base plate 61, and the wedge block 64 is connected to the middle of the vertical plate 62. The vertical plate 62 has multiple second threaded holes 621, which are located on both sides of the wedge block 64. The base plate 61 has a base plate connecting hole 611 and the second threaded holes 621. The wedge block 64 is used. When locking the base 2, the wedge block 64 is placed against the second inclined surface 92 of the base 2, and then the base plate 61 is fixed to the frame 1 by fasteners. When locking the base 2 using fastener 63, the base plate 61 is first fixed to the frame 1 by fasteners, and then the fastener 63 is connected to the upright plate 62. The base 2 is locked by rotating the fastener 63. This locking seat integrates fastener 63 and wedge block 64, and different locking methods can be flexibly switched without disassembling and replacing different locking seats, resulting in higher locking efficiency.
[0049] In one embodiment of this utility model, the fastener includes a screw, a threaded rod, and a nut.
[0050] Reference Figure 1 As shown, in one embodiment of this utility model, a protective cover 11 is also included, which is sleeved on the synchronous belt, the first synchronous pulley 51 and the second synchronous pulley 52.
[0051] Reference Figure 1As shown, in one embodiment of the present invention, the frame 1 is provided with a limiting seat 7, which is disposed at one end of the base 2 along the moving direction, and is used to limit the base 2 to prevent the limiting seat 7 from detaching from the frame 1.
[0052] Reference Figure 1 As shown, in one embodiment of this utility model, a reducer support 8 is provided on the frame 1, and the reducer is fixedly connected to the reducer support 8 through the reducer connection hole 81.
[0053] The working principle of the flexible connection driving device described in this utility model is as follows:
[0054] The reducer is fixedly mounted on the reducer bracket 4, the servo motor is mounted on the base 2, the first synchronous pulley 51 is mounted on the output shaft 3 of the servo motor, and the second synchronous pulley 52 is mounted on the input shaft 4 of the reducer. Then, a synchronous belt is used to engage the first synchronous pulley 51 and the second synchronous pulley 52. The base 2 is moved to precisely adjust the center distance between the first synchronous pulley 51 and the second synchronous pulley 52 until the synchronous belt obtains the preset optimal tension. Finally, the base 2 is locked using the locking assembly. The winding motor is connected to the motor power supply and control system, and the output shaft of the reducer is connected to the roll shaft of the slitting machine. After the winding motor starts, the output shaft 3 drives the input shaft 4 to rotate using the synchronous belt. After the input shaft 4 is reduced in speed, it drives the output shaft of the reducer to rotate, and the output shaft of the reducer drives the roll shaft to rotate. Example
