DETAILED DESCRIPTION
[0019] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.
[0020] Example: A device for uniformly twisting polyester core-spun sewing thread, such as... Figures 1-3 As shown, the assembly includes a movable base 1, a turntable 2, a gear ring 5, a gear 6, a second motor 7, a guide plate 8, a clamping plate 9, and a top column 91. The turntable 2 is rotatably mounted on the front of the movable base 1. The turntable 2 has a ring of through holes 3 and a ring of trapezoidal grooves 21 evenly spaced along its circumference. The through holes 3 are for passing through the sewing thread and are located outside the trapezoidal grooves 21. In a specific embodiment, the sewing thread to be twisted is passed through the corresponding through hole 3 as needed. The ring of through holes 3 and the ring of trapezoidal grooves 21 allows the user to select an appropriate number of through holes 3 for operation according to the usage scenario. A connecting groove is provided between the through holes 3 and the trapezoidal grooves 21. The clamping plate 9, slidably disposed within the trapezoidal groove 21, extends into the through hole 3 along the groove. The inner wall of the through hole 3 has evenly spaced grooves, and the end of the clamping plate 9 extending into the through hole 3 has evenly spaced protrusions. The protrusion engages with the groove. When the protrusion on the clamping plate 9 engages with the groove on the inner wall of the through hole 3, the clamping plate 9 can limit the sewing thread passing through the through hole 3, thereby preventing the sewing thread from shifting during twisting. The clamping plate 9 is provided with a top post 91, which slides in cooperation with the annular wave groove on the guide plate 8 rotatably mounted on the back of the turntable 2. The inner ring of the guide plate 8 is connected to a gear ring 5, which meshes with multiple gears 6 rotatably mounted on the back of the turntable 2. The gears 6 are connected to each other through a pulley assembly. The output shaft of the second motor 7 mounted on the back of the turntable 2 is connected to a gear 6. The second motor 7 drives the gear 6 to rotate, thereby driving the rack to rotate. The rack drives the guide plate 8 to rotate, thereby causing the top post 91 to move along the annular wave groove on the guide plate 8, thus pushing the clamping plate 9 into the through hole 3 and abutting against the inner wall of the through hole 3.
[0021] like Figure 1 and Figure 2 As shown, a first motor 4 is installed on the movable base 1 to drive the turntable 2 to rotate. The first motor 4 drives the turntable 2 to rotate, so that the threads passing through the through hole 3 are joined together to form a sewing thread. The turntable 2 rotates at a constant speed, so that the sewing threads are evenly twisted together.
[0022] like Figure 4As shown in the drawings, the front part of the moving seat 1 is rotatably installed with a rotating rod 10, and the rotating rod 10 is installed with an n-shaped rod 11 side by side, and the n-shaped rod 11 is rotatably installed with a guide wheel 12 away from the horizontal part of the rotating rod 10, and the sewing thread is threaded through the guide wheel 12, and the guide wheel 12 guides the sewing thread, and the height of the guide wheel 12 is adjusted by rotation to adjust the tension of the sewing thread, and the twisting operation is facilitated.
[0023] As shown in the drawings, Figure 5 The n-shaped rod 11 is installed with a ring-shaped mounting frame 13, and the sewing thread is threaded through the ring-shaped mounting frame 13, and the ring-shaped mounting frame 13 is threadedly connected with threaded rods 14 on both sides, and the threaded rods 14 are rotatably connected with arc-shaped limiting plates 15 at the ends threaded into the ring-shaped mounting frame 13, and the threaded rods 14 on both sides of the ring-shaped mounting frame 13 can adjust the position of the arc-shaped limiting plates 15 to adapt to different thicknesses of the sewing thread and provide appropriate tension control.
[0024] As shown in the drawings, Figure 1 The rotating disc 2 is connected with guide cylinders 16 on both sides of the through hole 3, and the guide cylinders 16 are used to guide the sewing thread into the through hole 3 to reduce the operation difficulty and improve the efficiency.
[0025] In use, first, the plurality of sewing threads to be twisted together are threaded through the ring-shaped mounting frame 13, and then threaded around the guide wheel 12, and finally threaded into the through hole 3 on the rotating disc 2, and the second motor 7 drives the gear 6 to rotate, and the gear 6 drives the guide disc 8 to rotate through the meshing with the gear ring 5, so that the top column 91 moves along the annular wavy groove on the guide disc 8, thereby driving the clamping plate 9 to move along the sliding groove to the direction of the through hole 3, until the clamping plate 9 abuts against the inner wall of the through hole 3, that is, the top column 91 moves to the longest diameter point of the inner circle of the guide disc 8, at which time the second motor 7 is powered off, and the end of the sewing thread is effectively fixed through the abutting cooperation of the clamping plate 9 and the inner wall of the through hole 3; at this time, the first motor 4 is powered on, and the first motor 4 drives the rotating disc 2 to rotate, and the rotating disc 2 rotates to combine the plurality of sewing threads into a complete sewing thread, and at the same time, the plurality of sewing threads are twisted into a sewing thread by moving the moving seat 1 horizontally backward, thereby achieving the effect of twisting the plurality of sewing threads into a sewing thread, and the clamping plate 9 fixes the sewing thread while the rotating disc 2 rotates, thereby avoiding the deviation or knotting of the sewing thread in the twisting process, and ensuring the quality and uniformity of the twisted thread.
[0026] The above embodiments are provided for those skilled in the art to implement or use the utility model, and those skilled in the art can make various modifications or changes to the above embodiments without departing from the utility model idea of the utility model, and therefore the protection scope of the utility model is not limited by the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
