Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1:

[0028] As Figures 1 to 6As shown, the present invention provides a technical solution of a rewinding device for a winding machine: it comprises a bottom plate 1, a support plate 2 is arranged on the upper surface of the bottom plate 1, and a bobbin adjustment mechanism 4 is arranged on the support plate 2, the bobbin adjustment mechanism 4 is used to adjust a plurality of bobbin tubes placed on the support plate 2 to be directly below a yarn guide ring 3, the bobbin adjustment mechanism 4 comprises a support column 41, a moving column 42, a placement plate 43, a positioning head column 44, a toggle rod 45, a sliding block 46, a toggle block 47 and a conversion adjustment component 5, the lower surface of the support plate 2 is fixedly supported on the upper surface of the bottom plate 1 by a plurality of support columns 41, a plurality of guide slots 21 penetrating up and down are provided on the support plate 2, and a moving column 42 is slidably arranged in each guide slot 21, a placement plate 43 is arranged on the upper end surface of each of the moving columns 42, and a positioning head column 44 is arranged on the upper surface of the right circular disc of the placement plate 43, a driving motor is fixedly arranged on the upper surface of the bottom plate 1, and the output shaft of the driving motor is connected to the toggle lever 45 through the conversion adjustment component 5 The side of the toggle lever 45 is provided with a sliding groove 451, and a sliding block 46 is slidably arranged in the sliding groove 451, and the outer side of the sliding block 46 is provided with a C-shaped toggle block 47, and the notch of the C-shaped toggle block 47 is rotationally aligned with the outer ring surface of the bottom end of the moving column 42 extending from the lower surface of the support plate 2; when working, when it is necessary to use the bobbin machine to rewind the yarn on the bobbin, since the bottom plate 1 of the existing rewinding device is only provided with a single fixing device and a guide The yarn ring 3 is aligned, and then the fixed yarn tube is rewound. Therefore, when the rewinding device rewinds the yarn tube, the processing personnel need to manually replace the yarn tube that has been rewound, and then install the new yarn tube on the fixing device directly below the yarn guide ring 3, thereby affecting the yarn rewinding efficiency of the rewinding device on the winding machine. Even if multiple fixing devices are set on the bottom plate 1, the multiple fixing devices cannot align the yarn guide ring 3, thereby affecting the normal yarn guiding processing of the yarn guide ring 3;Therefore, the present invention provides a support plate 92 on the bottom plate 1 and a bobbin adjustment mechanism 4 on the support disk 2. When it is necessary to reverse the yarn on the bobbin, the processing personnel will sequentially sleeve multiple bobbin tubes on the positioning head column 44 for fixing. When it is necessary to reverse the yarn on one of the bobbin tubes, the processing personnel will control the conversion and adjustment component 5 to work, so that it drives the toggle rod 45 to rotate to the position directly below the moving column 42 on the support disk 2, and then the conversion and adjustment component 5 drives the toggle rod 45 to move toward the lower surface of the support disk 2. At this time, the notch of the C-shaped toggle block 47 will be sleeved on the moving column 42, and then the conversion and adjustment component 5 will pull the sliding block 46 to slide in the sliding groove 451 opened on the toggle rod 45 toward the center position of the support disk 2. At this time, the sliding sliding block 46 will drive the moving column 42 to slide in the guide slide groove 21 through the C-shaped toggle block 47. Since the top of the moving column 42 is fixed with a bobbin through the placement disk 43 and the positioning head column 44, Therefore, the sliding of the moving column 42 will pull the fixed bobbin to slide toward the center of the support disk 2. Since the structure of the placement disk 43 is similar to that of a table tennis racket, the bobbin is fixed at the center of the racket of the placement disk 43. Then, the placement disk 43 slides toward the center and drives the fixed bobbin to move to the center of the yarn guide ring 3. Then, the free end of the yarn on the bobbin passes through the yarn guide ring 3, and then the rewinding operation can be performed. When the yarn on the bobbin located directly below the yarn guide ring 3 is completed, the conversion and adjustment component 5 will work in the reverse direction, so that the sliding block 46 drives the moving column 42 to move toward the outer ring surface of the support disk 2 through the C-shaped toggle block 47. At this time, the moving column 42 will drive the bobbin completed by the wire fixed by the positioning head column 44 to detach from the bottom of the yarn guide ring 3. Then, the conversion and adjustment component 5 continues to repeat the above steps, so that the bobbin at other positions of the support disk 2 can be moved to the bottom of the yarn guide ring 3, so that the normal rewinding of the yarn on the bobbin can be realized. ;

[0029] As an embodiment of the present invention, the conversion and adjustment assembly 5 includes an electric push rod 51, a rotating column 52, a limiting strip 53 and a driving shaft 54. An electric push rod 51 is fixedly arranged below the center position of the support disk 2, and the bottom end surface of the piston rod of the electric push rod 51 is rotatably provided with a rotating column 52. A toggle rod 45 is sleeved on the rotating column 52, and a plurality of limiting strips 53 are arranged on the outer circumferential surface of the bottom end of the rotating column 52. The upper end of the output shaft of the driving motor is connected with a driving shaft 54, and a positioning slot 541 is vertically opened inside the top end surface of the driving shaft 54. The positioning slot 541 is slidably inserted and aligned with a plurality of limiting strips 53 arranged on the rotating column 52. During operation, when it is necessary to drive the toggle rod 45 to rotate to directly below the moving column 42 and make the C-shaped toggle block 47 slide and fit onto the outer circumferential surface of the moving column 42, at this time, the processing personnel can control the driving motor on the upper surface of the bottom plate 1 to work through the PLC control system. The driving motor will drive the driving shaft 54 to rotate through the output shaft. Since the rotating column 52 will slide into the positioning slot 541 opened at the top end of the driving shaft 54, and a plurality of limiting strips 53 arranged on the outer circumferential surface of the rotating column 52 will be inserted into the square notch of the positioning slot 541, therefore, the rotation of the driving shaft 54 will drive the rotating column 52 to rotate through the limiting strips 53. Furthermore, the rotating column 52 will drive the toggle rod 45 to rotate to the side directly below the corresponding moving column 42 on the lower surface of the support disk 2, so that the notch of the C-shaped toggle block 47 is aligned with the moving column 42. Then, control the piston rod of the electric push rod 51 to contract, so that it drives the toggle rod 45 to approach the lower surface of the support disk 2 through the rotating column 52. At this time, the notch of the C-shaped toggle block 47 will fit onto the circumferential surface of the moving column 42, and when the rotating column 52 moves upward, it will drive the limiting strips 53 to disengage from the positioning slot 541, so that when the driving motor continues to drive the driving shaft 54 to rotate, the toggle rod 45 will not continue to rotate on the lower surface of the support disk 2. Furthermore, it is convenient for the driving shaft 54 to drive the sliding block 46 to slide in the sliding slot 451 opened on the side of the toggle rod 45, so as to realize that the moving column 42 drives the yarn tube fixed by the positioning head column 44 to move to directly below the yarn guide ring 3.

[0030] As an embodiment of the present invention, the conversion adjustment component 5 also includes a winding drum 55, a limit stop bar 56 and a pull rope 57. The winding drum 55 is rotatably arranged on the lower surface of the toggle rod 45 sleeved on the rotating column 52 through a bearing, and the winding drum 55 is sleeved on the outer ring surface of the driving shaft 54. A plurality of limit stop bars 56 are vertically arranged on the outer ring of the upper end surface of the driving shaft 54, and a plurality of limit stop bars 56 are vertically arranged on the inner ring surface of the bottom end of the winding drum 55. The plurality of limit stop bars 56 on the inner ring of the winding drum 55 and the limit stop bars 56 on the outer ring of the driving shaft 54 are arranged to slide up and down in an offset manner. A pull rope 57 is wound around the winding drum 55, and the free end of the pull rope 57 passes through the sliding groove 451 of the toggle rod 45 and is connected to the side of the sliding block 46. The other side of the sliding block 46 is connected to the side wall of the sliding groove 451 through a spring.During operation, when it is necessary to drive the moving column 42 to drive the bobbin fixed on the positioning head column 44 to move to the center position of the support disk 2, at this time, the electric push rod 51 will drive a plurality of limiting strips 53 to disengage from the positioning slot 541 through the rotating column 52. When the rotating column 52 drives the toggle rod 45 to move upward, at this time, the toggle rod 45 will drive the winding drum 55 to move upward on the outer circumferential surface of the drive shaft 54, so that the limiting strip 56 on the inner circumferential surface of the winding drum 55 is in mutual contact and fit with the limiting strip 56 on the outer circumferential surface of the drive shaft 54. Therefore, when the drive motor is continuously controlled to rotate, at this time, the drive shaft 54 will drive the winding drum 55 to rotate through the mutually contacting limiting strips 56. At this time, the rotation of the winding drum 55 will wind the pull rope 57. Since the free end of the pull rope 57 is connected to the side surface of the sliding block 46, the winding of the pull rope 57 will pull the sliding block 46 to move towards the center of the support disk 2 in the sliding groove 451. At this time, the sliding block 46 will stretch the spring on its side surface, and the movement of the sliding block 46 towards the center of the support disk 2 will drive the fixed bobbin to move to the center position of the support disk 2 through the moving column 42 sleeved by the C-shaped toggle block 47, thereby moving the bobbin located on the outer circle of the support disk 2 to directly below the yarn guide ring 3, which is convenient for the yarn guide ring 3 to safely guide the yarn on the bobbin. When the yarn on the bobbin located below the yarn guide ring 3 is finished and the bobbin needs to be replaced, at this time, the drive motor is controlled to rotate in the reverse direction, so that the winding drum 55 slowly releases the wound pull rope 57. At this time, the sliding block 46 moves towards the outer end surface of the toggle rod 45 in the sliding groove 451 under the elastic restoring force of the side spring, and then drives the moving column 42 to move towards the outer circumferential surface of the support disk 2 through the C-shaped toggle block 47, so that the bobbin after the winding is completed moves to the initial position on the outer circumferential surface of the support disk 2. Then, by the extension of the electric push rod 51, the toggle rod 45 drives the C-shaped toggle block 47 to disengage from the side surface of the moving column 42 in socket contact. At this time, the limiting strip 53 on the side surface of the rotating column 52 will slide and insert into the positioning slot 541, and at this time, the limiting strip 56 on the inner circumferential surface of the winding drum 55 will disengage from the contact and fit with the limiting strip 56 on the outer circumferential surface of the drive shaft 54. Furthermore, the continuous rotation of the drive motor will drive the toggle rod 45 to rotate and move to below the next moving column 42, and then repeat the above actions, so that the other bobbins on the support disk 2 that have not been yarn-guided can be moved to directly below the yarn guide ring 3 for yarn guiding treatment. Furthermore, it is not necessary for the processing personnel to frequently manually replace the bobbins, thereby improving the efficiency of the winding device for winding the yarn on the bobbins.

[0031] As an embodiment of the present invention, a positioning rod 6 is provided on the lower surface of the support plate 2, and the positioning rod 6 is located on the side of the electric push rod 51, and a plurality of positioning holes 452 are provided on the upper surface of the toggle rod 45, and the plurality of positioning holes 452 are slidably plugged and aligned with the upper positioning rod 6; during operation, in order to prevent the toggle rod 45 from rotating when the sliding block 46 slides in the sliding groove 451 of the toggle rod 45, therefore, when the piston rod of the electric push rod 51 drives the toggle rod 45 to move upward through the rotating column 52, the positioning column provided on the lower surface of the support plate 2 will be inserted into one of the positioning holes 452 provided on the upper surface of the toggle rod 45, so that the positioning rod 6 can play a role of limiting the rotation of the toggle rod 45 moving upward, thereby preventing the toggle rod 45 from rotating when the sliding block 46 slides in the sliding groove 451 under the pulling force of the pull rope 57.

[0032] As an embodiment of the present invention, a soft magnet 7 is provided on the inner wall of the notch of the C-shaped toggle block 47, and a metal ring 8 is provided on the outer ring surface of the lower end of the moving column 42, and the metal ring 8 and the energized soft magnet 7 are magnetically attracted to each other; during operation, in order to improve the stability of the connection between the C-shaped toggle block 47 and the moving column 42, when the notch of the C-shaped toggle block 47 contacts the outer wall of the moving column 42 upward under the drive of the toggle rod 45, the soft magnet 7 is energized at this time, so that the soft magnet 7 generates a magnetic attraction force and is attracted to the metal ring 8 on the outer ring of the moving column 42, thereby realizing a stable connection between the C-shaped toggle block 47 and the moving column 42, and preventing the sliding block 46 from sliding in the sliding groove 451. Due to the unstable connection between the C-shaped toggle block 47 and the moving column 42, the moving column 42 and the C-shaped toggle block 47 are separated, thereby affecting the stable sliding of the yarn tube on the support plate 2.

[0033] As an embodiment of the present invention, the yarn guide ring 3 is arranged at the center position above the support plate 92 through a support adjustment mechanism 9, and the support adjustment mechanism 9 is used to adjust the height of the yarn guide ring 3; the support adjustment mechanism 9 includes a support screw 91, a support plate 92 and a rotating nut 93, the upper surface of the base plate 1 is fixedly provided with a support screw 91, a support plate 92 is slidably sleeved on the support screw 91, and a yarn guide ring 3 is provided on the right end surface of the support plate 92, and two nuts are threadedly connected on the support screw 91, and the two nuts are respectively rotated and fitted with the upper and lower surfaces of the support plate 92; when working, when it is necessary to adjust the height of the yarn guide ring 3, It is used to adapt to yarns of different gram weights wound on the yarn tube. If the yarn guide ring 3 needs to be adjusted downward, the processing personnel first rotates the rotating nut 93 under the support plate 92 to make it move downward around the support screw 91. At this time, the support plate 92 will slide downward under its own gravity, and then the rotating nut 93 on the top is rotated to make it contact with the upper surface of the support plate 92, and then the yarn guide ring 3 is adjusted downward; and when the height of the yarn guide ring 3 needs to be adjusted upward, the rotating nut 93 on the top of the support plate 92 is first rotated to make it disengage from the upper surface of the support plate 92, and then the rotating nut 93 on the bottom is rotated, so as to facilitate the height adjustment of the yarn guide ring 3.

[0034] As an embodiment of the present invention, the outer ring surface of the positioning head column 44 is wrapped with an elastic silicone layer, and the elastic silicone layer is in extrusion contact with the inner ring surface of the yarn tube sleeved on the positioning head column 44. During operation, wrapping the elastic silicone layer on the positioning head column 44 can increase the friction with the inner diameter of the yarn tube, thereby improving the stability of the installation of the yarn tube on the positioning head column 44.

[0035] As an embodiment of the present invention, at least four support columns 41 are provided; and the outer circumferential surfaces of the base plate 1 are arranged in arc shapes.

[0036] Working principle: when it is necessary to reverse the yarn on the bobbin, the processing personnel will sequentially sleeve multiple bobbin tubes on the positioning head column 44 for fixing. When it is necessary to reverse the yarn on one of the bobbin tubes, the processing personnel will control the conversion and adjustment component 5 to work, so that it drives the toggle rod 45 to rotate to the position directly below the moving column 42 on the support disk 2, and then the conversion and adjustment component 5 drives the toggle rod 45 to move toward the lower surface of the support disk 2. At this time, the notch of the C-shaped toggle block 47 will be sleeved on the moving column 42, and then the conversion and adjustment component 5 will pull the sliding block 46 to slide in the sliding groove 451 opened on the toggle rod 45 toward the center position of the support disk 2. At this time, the sliding sliding block 46 will drive the moving column 42 to slide in the guide groove 21 through the C-shaped toggle block 47. Since the top of the moving column 42 is fixed with a bobbin through the placement disk 43 and the positioning head column 44, the sliding of the moving column 42 will pull the fixed yarn The tube moves and slides toward the center position of the support disk 2. Since the structure of the placement disk 43 is similar to that of a table tennis racket, the yarn tube is fixed at the center position of the racket of the placement disk 43. Then, the placement disk 43 sliding toward the center position will drive the fixed yarn tube to move to the center position of the yarn guide ring 3, and then the free end of the yarn on the yarn tube passes through the yarn guide ring 3, and then the rewinding work can be performed; and when the yarn on the yarn tube located directly below the yarn guide ring 3 is completed, the conversion and adjustment component 5 will work in the reverse direction, so that the sliding block 46 drives the moving column 42 to move toward the outer ring surface of the support disk 2 through the C-shaped toggle block 47. At this time, the moving column 42 will drive the yarn tube completed by the wire fixed by the positioning head column 44 to detach from the bottom of the yarn guide ring 3, and then the conversion and adjustment component 5 continues to repeat the above steps, so that the yarn tube at other positions of the support disk 2 can be moved to the bottom of the yarn guide ring 3, so that the normal rewinding of the yarn on the yarn tube can be realized.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
