Description

Technical Field

[0001] The present invention relates to the technical field of winding machines, and particularly to an enameled wire winding machine for a detachable winding head. Background Art

[0002] A winding machine is a device that winds a linear object around a specific workpiece, usually used for the winding of enameled wire. A winding machine generally includes a wire feeding mechanism, a winding mechanism, and other auxiliary mechanisms. During winding, the winding mechanism drives a reel to rotate to wind the enameled wire, and at the same time, the wire feeding mechanism continuously transports the enameled wire. During the winding process, the winding head drives the enameled wire to move left and right, so that the enameled wire is evenly wound on the reel.

[0003] When the winding of the enameled wire on the reel is completed, the reel needs to be replaced. During the process of replacing the reel in the existing winding machine, it is necessary to pause for a period of time, and the winding of the next reel can only be carried out after the replacement of the reel is completed. The replacement of the reel takes a certain amount of time, which affects the working efficiency of the winding machine; moreover, before winding, it is necessary to re-fix the end of the enameled wire so that the enameled wire can be wound on the reel when the reel rotates. The process of fixing the wire head also takes a certain amount of time, which affects the working efficiency of the winding machine. Summary of the Invention

[0008] In one possible implementation, an arc-shaped guide rod for guiding the enameled wire is fixedly connected to the front side of the fixed seat, a through groove for the wire cutting blade to pass through is provided at the bottom of the arc-shaped guide rod, and the top end of the arc-shaped guide rod is bent backward and extends above the wire clamping plate.

[0009] In one possible implementation, the separation assembly includes a multi-stage telescopic rod fixedly connected to a fixed seat and located below a rotating shaft, an end of the multi-stage telescopic rod away from the fixed seat is fixedly connected to a movable seat, a return spring 1 located below the multi-stage telescopic rod is fixedly connected between a side of the movable seat close to the fixed seat and an outer wall of the fixed seat, and an end of the rotating sleeve away from the fixed seat is rotatably connected to the top of the movable seat via a fixedly connected central axis.

[0010] In one possible implementation, a limit assembly for limiting the central axis is also installed inside the movable seat, and the limit assembly includes a movable rod movably installed up and down inside the movable seat, and a friction plate for frictionally limiting the central axis is fixedly connected to the top of the movable rod, and the upper surface of the friction plate is in conflict with the outer ring surface of the central axis, and a compression spring is fixedly connected between the bottom of the friction plate and the inner wall of the movable seat, and a release component for driving the friction plate to move downward to release the limit is also installed at the bottom of the movable rod.

[0011] In one possible implementation, the limit-releasing component includes a rectangular frame fixedly connected to the bottom of the movable rod, a wedge-shaped rod is slidably installed on the telescopic section of the multi-stage telescopic rod away from the fixed seat, the inclined surface of the wedge-shaped rod away from the fixed seat is slidably matched with the bottom frame of the rectangular frame, the end of the wedge-shaped rod close to the fixed seat protrudes to the outside of the telescopic section of the multi-stage telescopic rod away from the fixed seat, a retaining ring is fixedly sleeved on the wedge-shaped rod, and a reset spring 2 is fixedly connected between the end of the retaining ring away from the fixed seat and the inner wall of the telescopic section of the multi-stage telescopic rod.

[0014] Advantages of the present invention: 1. By providing two rotating sleeves in the present invention, when the winding of the winding drum installed on one rotating sleeve is completed, the servo moving platform can drive the wire winding head to move to another rotating sleeve to continue winding. At this time, the winding drum with completed winding can be replaced, and there is no need to pause the winding machine to replace the winding drum, improving the working efficiency of the winding machine; and during the movement of the enameled wire from one winding drum to another, the enameled wire is clamped by the arc-shaped wire clamping groove and the wire clamping teeth, and the enameled wire is driven to move to the tangent blade for cutting, avoiding the connection and entanglement of the enameled wire on the two winding drums, and there is no need to additionally fix the end of the enameled wire, further improving the working efficiency of the winding machine.

[0016] 3. In the present invention, the rotating sleeve, the separation component, the limiting component and the locking mechanism cooperate with each other to drive the rotating sleeve to be quickly separated from the rotating shaft. When the winding drum on the rotating sleeve needs to be replaced, the unlocking component is used to drive the wedge block to release the locking of the corresponding separation component, so that the separation component pushes the corresponding separation component to be quickly separated from the rotating shaft, and the limiting component limits the rotating sleeve during the separation process, so that the rotating sleeve quickly stops rotating, facilitating the replacement of the winding drum on the rotating sleeve, and further improving the working efficiency of the wire winding work of the winding machine.

Detailed implementation manners

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manners disclosed below.

[0029] Please refer to Figure 1 , Figure 3 and Figure 10, An enameled wire winding machine for detachable wire winding heads, including a frame 1 and a wire feeding mechanism 2 installed on the top of the frame 1, and further including a winding mechanism 3. The winding mechanism 3 includes a fixed seat 31 fixedly installed on the top of the frame 1. On the fixed seat 31, a rotating shaft 32 that is symmetric left and right and coaxially connected is rotatably installed. A rotating sleeve 33 for installing a reel is movably sleeved on the rotating shaft 32. A number of permanent magnets are circumferentially and evenly installed inside both the rotating shaft 32 and the rotating sleeve 33. The rotating shaft 32 and the rotating sleeve 33 are connected by magnetic force transmission. One end of the rotating sleeve 33 close to the fixed seat 31 is threadedly connected with a clamping plate 34 with an arc-shaped clamping groove 341. A cutting blade 35 is fixedly installed on the front side of the fixed seat 31. On both the left and right sides of the fixed seat 31, a separating component 36 for pushing the corresponding rotating sleeve 33 to move away from the rotating shaft 32 is fixedly connected.

[0030] Please refer to Figure 1 , Figure 2 and Figure 6 , a locking mechanism 4. The locking mechanism 4 includes a wedge block 41 that is slidably installed back and forth inside the frame 1 for locking the separating component 36. A third return spring 42 is fixedly connected between the rear side of the wedge block 41 and the inner wall of the frame 1. An unlocking component 43 for driving the wedge block 41 to move backward to unlock is also installed inside the frame 1.

[0031] Please refer to Figure 1 , the wire feeding mechanism 2 includes a servo moving platform 21 fixedly installed on the top of the frame 1 and located behind the fixed seat 31. A wire winding head 22 is detachably installed on the servo moving platform 21. The servo moving platform 21 is used to drive the wire winding head 22 to move left and right.

[0032] Please refer to Figure 1 , Figure 3 and Figure 5 , the screwing direction of the clamping plate 34 is opposite to the direction in which the rotating shaft 32 drives the rotating sleeve 33 to rotate and wind the wire. The arc-shaped clamping grooves 341 are circumferentially and evenly distributed around the clamping plate 34. One end of the arc-shaped clamping groove 341 close to the axis of the clamping plate 34 gradually becomes narrower. Clamping teeth 342 are fixedly installed on both side walls of the arc-shaped clamping groove 341, and the clamping teeth 342 on the two side walls are staggered.

[0033] Please refer to Figures 1 - 5, during specific use, first, the winding drum set is sleeved on the rotating sleeve 33, and then the wire clamping plate 34 is screwed clockwise onto the rotating shaft 32. The winding drum is fixed by the wire clamping plate 34, so that the winding drum rotates together with the rotating sleeve 33. Then, the rotating sleeve 33 is sleeved on the rotating shaft 32, and then the end of the enameled wire is slid from the large-mouth end to the small-mouth end of the arc-shaped wire clamping groove 341, so that the wire clamping teeth 342 clamp the end of the enameled wire. After that, the rotating shaft 32 drives the rotating sleeve 33 to rotate counterclockwise through magnetic force, so that the rotating sleeve 33 drives the winding drum to wind the enameled wire. By adopting the magnetic connection method, the rotating shaft 32 drives the rotating sleeve 33 to rotate. Only by sleeving the rotating sleeve 33 on the rotating shaft 32 can the rotating shaft 32 drive the rotating sleeve 33 to rotate to realize the winding of the enameled wire. When replacing the winding drum subsequently, there is no need to pause the rotation of the rotating shaft 32 to disassemble and assemble the rotating sleeve 33, improving the working efficiency of the winding machine.

[0034] Taking the winding of the left winding drum as an example, when the left winding drum finishes winding, the servo moving platform 21 drives the wire winding head 22 to quickly move to the right winding drum. During the movement, since the enameled wire is still connected to the left winding drum, when the enameled wire moves to the right, it will stick to the edge of the left wire clamping plate 34 and slide into the arc-shaped wire clamping groove 341 when the wire clamping plate 34 rotates. Due to the gradual narrowing of the arc-shaped wire clamping groove 341, the enameled wire will be clamped by the arc-shaped wire clamping groove 341 and the corresponding wire clamping teeth 342; when the enameled wire enters the arc-shaped wire clamping groove 341 on the left side, the enameled wire will stick to the edge of the right wire clamping plate 34 and slide into the arc-shaped wire clamping groove 341 when the wire clamping plate 34 rotates, and will be clamped by the arc-shaped wire clamping groove 341 and the wire clamping teeth 342 on the right side. After that, with the rotation of the left and right rotating sleeves 33, the enameled wire located between the left and right wire clamping plates 34 will be brought to the tangent blade 35 to be cut off, preventing the enameled wires on the left and right winding drums from being connected and wound around each other.

[0035] After that, as the right rotating sleeve 33 drives the right winding drum to continue rotating, the enameled wire is wound onto the right winding drum. Since the arc-shaped wire clamping groove 341 and the wire clamping teeth 342 have clamped the enameled wire, the cut enameled wire will not be scattered, and there is no need to fix the end of the enameled wire additionally, further improving the working efficiency of the winding machine.

[0036] Please refer to Figures 1 - 3 , a curved guiding rod 351 for guiding the enameled wire is fixedly connected to the front side of the fixed seat 31. A through groove for the tangent blade 35 to pass through is opened at the bottom of the curved guiding rod 351, and the top end of the curved guiding rod 351 bends backward and extends above the wire clamping plate 34.

[0037] The enameled wire is guided by setting the arc-shaped guide rod 351. When the enameled wire moves from one reel to another, the enameled wire will adhere to the edge of the wire clamping plate 34. When the friction force at the edge of the wire clamping plate 34 is too large to allow the enameled wire to smoothly slide into the arc-shaped wire clamping groove 341, the enameled wire will move towards the arc-shaped guide rod 351 driven by the wire clamping plate 34. By using the blocking of the arc-shaped guide rod 351 on the enameled wire, the enameled wire can slide along the edge of the wire clamping plate 34 and smoothly enter the arc-shaped wire clamping groove 341. And as the wire clamping plate 34 rotates counterclockwise, the enameled wire will gradually move towards the narrower end of the arc-shaped wire clamping groove 341 under the guidance of the arc-shaped guide rod 351, improving the clamping effect of the arc-shaped wire clamping groove 341 and the wire clamping teeth 342 on the enameled wire. Finally, the enameled wire is guided to the tangent blade 35 for cutting.

[0038] Please refer to Figure 1 、 Figure 3 and Figure 4 As shown in, the separation assembly 36 includes a multi-stage telescopic rod 361 fixedly connected to the fixed seat 31 and located below the rotating shaft 32. One end of the multi-stage telescopic rod 361 away from the fixed seat 31 is fixedly connected with a movable seat 362. A first return spring 363 located below the multi-stage telescopic rod 361 is fixedly connected between one side of the movable seat 362 close to the fixed seat 31 and the outer wall of the fixed seat 31. One end of the rotating sleeve 33 away from the fixed seat 31 is rotationally connected to the top of the movable seat 362 through a fixedly connected central shaft.

[0039] Please refer to Figure 1 、 Figure 3 and Figure 4 As shown in, a limiting assembly 37 for limiting the central shaft is further installed inside the movable seat 362. The limiting assembly 37 includes a movable rod 371 movably installed up and down inside the movable seat 362. A friction plate 372 for frictionally limiting the central shaft is fixedly connected to the top of the movable rod 371. The upper surface of the friction plate 372 abuts against the outer ring surface of the central shaft. A compression spring 373 is fixedly connected between the bottom of the friction plate 372 and the inner wall of the movable seat 362. A limit release component for driving the friction plate 372 to move downward to release the limit is further installed at the bottom of the movable rod 371.

[0040] Please refer to Figure 3 and Figure 4The release component includes a rectangular frame 374 fixedly connected to the bottom of the movable rod 371, a wedge-shaped rod 375 is slidably installed on the telescopic section of the multi-stage telescopic rod 361 away from the fixed seat 31, and the inclined surface of the wedge-shaped rod 375 away from the fixed seat 31 is slidably matched with the bottom frame of the rectangular frame 374, and the end of the wedge-shaped rod 375 close to the fixed seat 31 protrudes to the outside of the telescopic section of the multi-stage telescopic rod 361 away from the fixed seat 31. A retaining ring 376 is fixedly sleeved on the wedge-shaped rod 375, and the retaining ring 376 is slidably installed on the inside of the telescopic section corresponding to the multi-stage telescopic rod 361 away from the fixed seat 31. A return spring 2 377 is fixedly connected between the end of the retaining ring 376 away from the fixed seat 31 and the inner wall of the telescopic section of the multi-stage telescopic rod 361.

[0041] See also Figure 1 , Figure 3 and Figure 4 When the rotating sleeve 33 has not yet been put onto the rotating shaft 32, the multi-stage telescopic rod 361 is in an extended state. At this time, the inclined surface of the wedge rod 375 and the rectangular frame 374 are in a separated state. The elastic force of the compression spring 373 is used to push the friction plate 372 upward, so that the friction plate 372 and the central axis on the rotating sleeve 33 are pressed together, preventing the rotating sleeve 33 from rotating at will, making it convenient to install and remove the reel on the rotating sleeve 33.

[0042] When the reel on the rotating sleeve 33 is installed, the movable seat 362 and the rotating sleeve 33 are pushed to move in the direction close to the fixed seat 31, so that the rotating sleeve 33 is mounted on the corresponding rotating shaft 32. At this time, the multi-stage telescopic rod 361 shrinks under the push of the movable seat 362. When the rotating sleeve 33 is about to be completely mounted on the rotating shaft 32, the end of the wedge rod 375 close to the fixed seat 31 will conflict with the outer wall of the fixed seat 31. As the multi-stage telescopic rod 361 continues to shrink, the end of the wedge rod 375 away from the fixed seat 31 will gradually insert into the corresponding rectangular frame 374. The inclined surface of the wedge rod 375 is used to guide the rectangular frame 374 to move downward, so that the rectangular frame 374 drives the movable rod 371 and the friction plate 372 to move downward, releases the limit of the friction plate 372 on the central axis, and enables the rotating sleeve 33 to rotate with the rotating shaft 32. At this time, the reset spring 2 377 is in a compressed and contracted state.

[0043] See also Figure 2 A driving motor 38 for driving the rotating shaft 32 to rotate is also installed inside the frame 1. The top of the output shaft of the driving motor 38 is connected to the rotating shaft 32 through a bevel gear set. The driving motor 38 drives the rotating shaft 32 to rotate counterclockwise through the transmission of the bevel gear set.

[0044] See also Figures 6 - 9, the unlocking component 43 includes a movable member 431 that is slidably mounted left and right inside the frame 1 and is located below the wedge block 41. Grooves are formed at both the left and right ends of the top of the movable member 431. Inside the grooves, guide blocks 432 are coaxially rotatably mounted through round rods. A cylinder that protrudes above the wedge block 41 is fixedly connected to the top of the guide block 432. A torsion spring 433 for driving the guide block 432 to rotate upward is mounted on the round rod. A guide groove 434 that is slidably engaged with the cylinder is formed at the bottom of the wedge block 41. The guide groove 434 is composed of two horizontally staggered horizontal segments and an inclined segment between the horizontal segments in the front and back. The cylinder is aligned left and right with the opening of the corresponding guide groove 434 away from the fixed seat 31.

[0045] Please refer to Figures 3 - 9 , during the process of the movable seat 362 approaching the fixed seat 31, the movable seat 362 will contact the inclined surface of the wedge block 41 and push the wedge block 41 to move backward until the movable seat 362 completely moves to the front side of the wedge block 41 and continues to approach the fixed seat 31. At this time, the return spring three 42 is compressed and contracted. When the rotating sleeve 33 is completely sleeved on the rotating shaft 32, the movable seat 362 moves to the side of the corresponding wedge block 41 close to the fixed seat 31. At this time, the return force of the return spring three 42 is used to push the wedge block 41 forward to block the movable seat 362 and prevent the movable seat 362 from moving under the action of the return force of the return spring one 363.

[0046] Taking the left reel starting to wind the wire as an example, in the initial state, the electric push rod 435 pushes the movable member 431 to slide leftward, so that the guide block 432 moves to the left side of the corresponding wedge block 41. When the left reel finishes winding the wire and the enameled wire on the reel has been cut off, the electric push rod 435 pushes the movable member 431 to move rightward. The movable member 431 drives the guide block 432 to move rightward. At this time, the cylinder at the top of the left guide block 432 will enter the corresponding guide groove 434. As the guide block 432 moves rightward, the cylinder will push the wedge block 41 to move backward under the guidance of the guide groove 434, so that the wedge block 41 releases the limit on the left movable seat 362. At this time, the left movable seat 362 will move leftward under the push of the return force of the corresponding return spring one 363, separating the left rotating sleeve 33 from the corresponding rotating shaft 32, facilitating the replacement of the reel on the left rotating sleeve 33 and improving the replacement efficiency.

[0047] During the rightward movement of the movable member 431, when the cylinder at the top of the right guide block 432 moves to contact the right wedge block 41, since the cylinder and the end of the guide groove 434 near the fixed seat 31 are offset, the right cylinder cannot enter the corresponding guide groove 434. At this time, with the rightward movement of the movable member 431, the right cylinder will drive the corresponding guide block 432 to rotate downward under the block of the wedge block 41, so that the right cylinder is hidden in the corresponding groove and moves rightward from under the right wedge block 41 until the cylinder moves to the right side of the right wedge block 41. At this time, the guide block 432 will rotate reversely under the action of the resilience of the corresponding torsion spring 433, so that the cylinder at the top of the guide block 432 stands up again, facilitating the subsequent unlocking of the right wedge block 41.
