[0025] The present invention is provided with a side pushing device. After the third motor starts working, it can drive the transmission rod to rotate, and then the transmission rod drives the cam tube to rotate, so that the spiral strip pushes the sliding column to move, and then the sliding column enters the end and disengages from the spiral strip.

[0038] Specifically, the bottom bracket 1 is used to support the entire component, and the head of the sewing thread is wound around the winding roller 4 installed on the vertical bracket 2 near one end of the side baffle 5. After the first motor 6 works, the winding roller 4 is driven to rotate to perform the winding work, and the provided clamping device 7 is used for positioning and clamping work when the sewing thread is wound. The provided side pushing device 8 is used to push the wound sewing thread to the side of the side baffle 5 to ensure that the sewing thread is wound more tightly and not loose.

[0039] See also Figure 2The clamping device 7 in the present invention includes a sliding seat 71, a slide rail 72, a connecting block 73, a pushing assembly 74, a pressure wheel 75, a reversing assembly 76 and a directional assembly 77. The slider at the rear middle part of the sliding seat 71 is slidably connected to the slide rail 72 installed on the side plate 3. The rear upper end of the sliding seat 71 is integrally connected with a connecting block 73. The rear middle part of the connecting block 73 is connected to the pushing assembly 74 installed on the side plate 3. A pressure wheel 75 is provided at the bottom of the sliding seat 71, and the pressure wheel 75 is located at the upper end of the winding roller 4. A reversing assembly 76 is provided inside the sliding seat 71. The bottom of the reversing assembly 76 is connected to the pressure wheel 75, and one side of the reversing assembly 76 is cooperated with the directional assembly 77 installed on the side plate 3.

[0040] Specifically, when winding the thread, the clamping device 7 is used for positioning and clamping. Under the push of the pushing component 74, the sliding seat 71 slides on the slide rail 72, and then the reversing component 76 is used to reverse left and right under the directional component 77, so that the clamping wheel 75 moves left and right and reverses. The clamping wheel 75 positions and clamps the sewing thread wound on the winding roller 4, so that the sewing thread is wound more evenly and more tightly.

[0041] See also Figure 3-Figure 4 The reversing assembly 76 of the present invention includes a reversing inner cylinder 761, a circular through groove 762, a reversing arm 763, a conical clamping block 764, a limit block 765, a first spring 766 and an adjustment mechanism 767. The reversing inner cylinder 761 is inserted into the circular through groove 762 in the middle of the sliding seat 71. The circular through groove 762 passes through the sliding seat 71 up and down, and one side of the upper end of the reversing inner cylinder 761 is connected to the reversing arm 763, and the other side is provided with a conical clamping block 764. A limit block 765 is slidably provided in the notch at the upper end of the connecting block 73, and the rear end of the limit block 765 is elastically connected to the connecting block 73 by the first spring 766. The conical clamping block 764 is connected to the arc surface of the front end of the limit block 765. An adjustment mechanism 767 is provided inside the reversing inner cylinder 761, and the bottom of the adjustment mechanism 767 is connected to the pressure wheel 75.

[0042] Among them, two stop posts 7101 are provided on one side of the upper part of the sliding seat 71. The two stop posts 7101 are used to limit the angle of the reversing arm 763 to prevent the reversing arm 763 from turning at an excessively large angle.

[0043] Specifically, the reversing inner cylinder 761 can rotate in the circular through groove 762 of the sliding seat 71, and the reversing arm 763 at the upper end extends between the first directional block 772 and the second directional block 773 of the directional assembly 77. When the sliding seat 71 moves left and right, the reversing inner cylinder 761 and the reversing arm 763 move left and right. When the reversing arm 763 moves to the left and is restricted by the first directional block 772, and the sliding seat 71 continues to move to the left, the reversing arm 763 is blocked by the first directional block 772 and changes direction to the right. When the reversing arm 763 moves to the right and is , restricted by the second directional block 773, and the sliding seat 71 continues to move to the right, then the reversing arm 763 is blocked by the second directional block 773 and changes direction to the left, thereby realizing the reversing work of the reversing inner cylinder 761, thereby driving the bottom clamping wheel 75 to change direction, and when the reversing arm 763 is reversing, the conical block 764 on the other side is subjected to force to push the limit block 765 backward and compress the first spring 766. After reversing, the limit block 765 limits the conical block 764 again through the reset of the first spring 766.

[0044] See also Figure 3 In the present invention, the adjustment mechanism 767 includes an adjusting inner block 7671, a square through slot 7672, a fixed wheel frame 7673, a second spring 7674, a fixed top frame 7675 and a top block 7676. The adjusting inner block 7671 is inserted into the square through slot 7672 in the middle of the reversing inner cylinder 761. The square through slot 7672 passes through the reversing inner cylinder 761 from top to bottom. A fixed wheel frame 7673 for fixing the pressure wheel 75 is installed at the bottom of the adjusting inner block 7671, and the upper end is connected to the second spring 7674. A fixed top frame 7675 is provided at the top of the reversing inner cylinder 761. A top block 7676 is provided inside the fixed top frame 7675, and the bottom of the top block 7676 is connected to the second spring 7674.

[0045] Among them, an adjusting bolt 76701 is installed in the threaded hole on the top of the fixed top frame 7675, and the bottom of the adjusting bolt 76701 is connected to the top block 7676. The adjusting bolt 76701 is used to adjust the position of the top block 7676, so that the upper and lower positions of the clamping wheel 75 can be adjusted. The adjusting bolt 76701 and the top block 7676 are movably connected, so that when the adjusting bolt 76701 rotates, it will not drive the top block 7676 to rotate.

[0046] Specifically, the adjusting inner block 7671 is inserted into the square through slot 7672 of the reversing inner cylinder 761, and the upper end of the adjusting inner block 7671 is connected to the top block 7676 in the fixed top frame 7675 through the second spring 7674, so that the adjusting inner block 7671 can elastically move up and down in the square through slot 7672 of the reversing inner cylinder 761, so that the pressure wheel 75 installed at the bottom of the fixed wheel frame 7673 can be adjusted in height, so that the pressure wheel 75 can better adapt to the thickness change of the sewing thread on the winding roller 4 when it is wound, thereby better positioning and pressing the sewing thread when it is wound.

[0047] See also Figure 5 In the present invention, the pushing assembly 74 includes a first mounting plate 741, a second motor 742, a first rotating frame 743 and a second rotating frame 744.

One end of the first rotating frame 743 is connected to the output end of the second motor 742, and the other end is rotatably connected to one end of the second rotating frame 744 through a shaft. The other end of the second rotating frame 744 is rotatably connected to the rear middle part of the connecting block 73 through a shaft.

[0048] Specifically, after the second motor 742 works, it can drive the first rotating frame 743 to rotate, and then the first rotating frame 743 drives the second rotating frame 744 to swing back and forth, and the second rotating frame 744 drives the connecting block 73 and the sliding seat 71 to move back and forth on the slide rail 72.

[0049] See also Figure 6 In the present invention, the orientation assembly 77 includes a second mounting plate 771, a first orientation block 772 and a second orientation block 773. One end of the second mounting plate 771 is mounted on the side plate 3, and the upper end of the second mounting plate 771 is respectively provided with a first orientation block 772 and a second orientation block 773 symmetrical to each other, and the reversing arm 763 extends between the first orientation block 772 and the second orientation block 773.

[0050] Specifically, the reversing arm 763 extends between the first directional block 772 and the second directional block 773 , and the first directional block 772 and the second directional block 773 limit the reversing arm 763 after it moves left and right, so that the reversing arm 763 changes direction.

[0051] See also Figure 7-9The side thrust device 8 of the present invention includes a fixed outer cylinder 81, a third motor 82, a pushing inner cylinder 83, a connecting groove 84, a cam cylinder 85, a transmission rod 86, a third spring 87, a spiral bar 88 and a sliding column 89. The fixed outer cylinder 81 is installed on the outer side of the side vertical plate 3, and the third motor 82 is installed at the rear end of the fixed outer cylinder 81. The pushing inner cylinder 83 is movably connected to the interior of the fixed outer cylinder 81 and elastically connected through the third spring 87. One end of the third spring 87 is connected to the rear end edge of the pushing inner cylinder 83, and the other end is connected to the rear end of the fixed outer cylinder 81, and is sleeved on the transmission rod 86. On the outside of the rod 86, a connecting groove 84 is provided in the middle of the front end of the pushing inner cylinder 83, and one end of the winding roller 4 is inserted into the connecting groove 84 of the pushing inner cylinder 83. The end of the winding roller 4 inserted into the connecting groove 84 is the end opposite to the side baffle 5. A cam cylinder 85 is provided at the rear end of the pushing inner cylinder 83, and a transmission rod 86 is connected to the middle of the rear of the cam cylinder 85. The transmission rod 86 is connected to the output end of the third motor 82, and a spiral strip 88 is provided on the outside of the cam cylinder 85. A sliding column 89 is provided on the inner rear wall of the pushing inner cylinder 83, and the sliding column 89 is slidably connected to the spiral strip 88 of the cam cylinder 85.

[0052] Among them, there are two groups of spiral strips 88 and sliding columns 89, and there is a space between the heads and tails of the two groups of spiral strips 88. The two groups of spiral strips 88 and the two groups of sliding columns 89 are symmetrically arranged, and are symmetrical at both ends of the cam cylinder 85, so that the cam cylinder 85 can better drive the push inner cylinder 83 to move after rotation. At the same time, there is a space between the heads and tails of the two groups of spiral strips 88, so that after the cam cylinder 85 moves inward, the two groups of sliding columns 89 enter the space between the heads and tails of the two groups of spiral strips 88, and the elasticity of the third spring 87 is used to reset the push inner cylinder 83 and push it outward, so that the push inner cylinder 83 can push the sewing thread on the winding roller 4 toward the side baffle 5, ensuring that the sewing thread is wound more tightly and not loosened.

[0053] Specifically, when winding the thread, the side pushing device 8 pushes the sewing thread to the side of the side baffle 5. After the third motor 82 works, it drives the transmission rod 86 to rotate, and the transmission rod 86 drives the cam cylinder 85 to rotate. The rotation of the cam cylinder 85 drives the two sets of spiral strips 88 to rotate, and the two sets of sliding posts 89 of the pushing inner cylinder 83 move from front to back on the two sets of spiral strips 88, so that the pushing inner cylinder 83 moves into the fixed outer cylinder 81. After the two sets of sliding posts 89 slide to the tail of the two sets of spiral strips 88 and enter the space between the head and tail of the two sets of spiral strips 88, the two sets of sliding posts 89 disengage from the two sets of spiral strips 88, and then the third spring 87 performs elastic reset to push the sliding post 89 back to the front end of the spiral strip 88, and the pushing inner cylinder 83 extends out of the fixed outer cylinder 81, and one end of the winding roller 4 extends into In the connecting groove 84 at the front end of the pushing inner cylinder 83, when the pushing inner cylinder 83 is extended, one end of the winding roller 4 can gradually enter the inside of the pushing inner cylinder 83, and the sewing thread wound on the winding roller 4 is pushed toward the side of the side baffle 5 through the front end of the pushing inner cylinder 83, so that the sewing threads after winding are gathered together more tightly and not easy to loosen, thereby improving the efficiency and quality of winding. After the two groups of sliding columns 89 disengage from the two groups of spiral strips 88, they re-enter the head of the spiral strips 88, thereby driving the pushing inner cylinder 83 to push back and forth. It should be noted that the pushing speed of the pushing inner cylinder 83 is proportional to the motor speed, that is, the faster the motor speed, the faster the pushing inner cylinder 83 pushes, and vice versa. The pushing speed of the pushing inner cylinder 83 can be synchronously adjusted according to the actual winding speed of the sewing thread, which will not be elaborated here.

[0054] The present invention provides a polyester sewing thread winding device and a winding method thereof, wherein a pressing device 7 is provided, and the sliding seat 71 can slide left and right on the slide rail 72 under the drive of the pushing component 74, and the reversing component 76 is stopped by the directional component 77 during movement to change direction, so that the pressing wheel 75 can move left and right and change direction left and right, and the sewing thread wound on the winding roller 4 can be effectively positioned and pressed, so that the sewing thread is more evenly wound after winding and is not easy to loosen after winding, thereby improving the winding efficiency and winding quality; the reversing component 76 and the directional component 77 are provided, and the reversing arm 763 on the reversing inner cylinder 761 is stopped by the first directional block 772 and the second directional block 773 when moving left and right. The cam 761 is rotated to move the tension wheel 75 at the bottom of the cam 762, so that the tension wheel 75 can move left and right and change direction left and right, so as to better cooperate with the winding of the sewing thread. An adjustment mechanism 767 is also provided inside the reversing assembly 76, and the upper end of the adjusting inner block 7671 is connected to the top block 7676 in the fixed top frame 7675 through a second spring 7674, so that the adjusting inner block 7671 can elastically move up and down in the square through groove 7672 of the reversing inner cylinder 761, so that the tension wheel 75 installed at the bottom of the fixed wheel frame 7673 can be adjusted in height, so that the tension wheel 75 can better adapt to the thickness change of the sewing thread on the winding roller 4 when the sewing thread is wound, so as to better position and press the sewing thread when it is wound.

[0055] The present invention is provided with a side pushing device 8, which can drive the transmission rod 86 to rotate after the third motor 82 is working, and then the transmission rod 86 drives the cam tube 85 to rotate, so that the spiral strip 88 pushes the sliding column 89 to move, and then the sliding column 89 enters the end and disengages from the spiral strip 88. The third spring 87 elastically resets the sliding column 89 to the front end, so that the pushing inner cylinder 83 can be telescopically movable in the fixed outer cylinder 81, and the sewing thread wound on the winding roller 4 is pushed toward the side of the side baffle 5 by the front end of the pushing inner cylinder 83, so that the wound sewing threads are gathered together more tightly and are not easy to loosen, thereby improving the efficiency and quality of winding.
