Description

Technical Field

[0001] This utility model relates to the field of sewing thread winding technology, and in particular to a sewing thread winding mechanism. Background Technology

[0002] After the sewing thread is produced, it needs to be wound onto a spool for easy use. Although existing winding machines can hold multiple spools at once, they also have the problem of low design efficiency. For example, when placing the spool on a fixed rod, bolts and other fasteners are usually used to fix the spool. The removal of the bolts will inevitably lead to a decrease in work efficiency.

[0003] An existing patent (publication number: CN220351307U) discloses a sewing thread winding mechanism, comprising a mounting shell, a base plate fixed to the bottom of the mounting shell, a motor fixed to the top of the base plate, a drive gear fixed to the output shaft of the motor, and several driven gears equidistantly meshing with the drive gear on the inner wall of the top of the mounting shell. A fixing rod penetrating the top of the mounting shell is fixed to the top of the driven gears. A washer rotatably mounted on the outer wall of the fixing rod is fixed to the outer wall of the fixing rod. A thread winding drum is inserted into the fixing rod, and a locking component is provided at the top of the fixing rod. The locking component includes a screw head fixed to the top of the fixing rod, and a threaded sleeve for compressing the thread winding drum is threadedly connected to the screw head. This invention allows multiple circularly arranged thread winding drums to rotate simultaneously, effectively improving work efficiency, making reasonable use of space, and featuring a simple, stable structure that is easy to maintain.

[0004] The above-mentioned sewing thread winding mechanism uses bolts to fix the thread drum. However, removing the bolts at the beginning and end of the winding process will inevitably consume a lot of time, resulting in reduced work efficiency. Therefore, we propose a sewing thread winding mechanism to solve the above problems. Utility Model Content

[0005] This invention provides a sewing thread winding mechanism, which solves the technical problem that the efficiency of current winding mechanisms is still low.

[0006] To solve the above-mentioned technical problems, this utility model provides a sewing thread winding mechanism, including a mounting shell, a driving gear disposed inside the mounting shell, a motor disposed at the bottom of the mounting shell, the output end of the motor being fixedly connected to the driving gear, a driven gear being meshed with the driving gear, a fixing rod being fixedly fixed at the top of the driven gear, a thread winding drum disposed on the fixing rod, a fixing component being disposed at the top of the fixing rod, and an anti-slip component being disposed between the thread winding drum and the fixing rod. The anti-slip component prevents the thread winding drum from sliding against the fixing rod, and the fixing component acts on the thread winding drum to fix the thread winding drum to the fixing rod.

[0007] Preferably, the fixing component includes a groove formed at the top of the fixing rod, a fixing block fixed at the top center of the groove, pressure plates hinged to the bottom two sides of the groove, and a spring provided between the fixing block and the pressure plates.

[0008] The above technical solution involves a fixing component with a groove at the top of a fixing rod. A fixing block is fixed at the center of the top of the groove, and pressure plates are hinged to both sides of the bottom of the groove. A spring is installed between the fixing block and the pressure plates. In the initial stage of winding, when the winding drum is placed on the fixing rod, two fingers are used to press the pressure plate to make it vertical. The other hand holds the winding drum and slides it off the fixing rod. As the winding drum is lowered, the spring force causes the pressure plate to return to a horizontal state, thus preventing the winding drum from detaching from the fixing rod and flying off during the winding process.

[0009] Preferably, the spring is arranged at an angle.

[0010] The above technical solution is adopted: the spring is set at an angle.

[0011] Preferably, one end of the spring is fixedly connected to the fixing block, and the end of the spring away from the fixing block is fixedly connected to the pressure plate.

[0012] The above technical solution is adopted: one end of the spring is fixedly connected to the fixed block, and the end of the spring away from the fixed block is fixedly connected to the pressure plate. The spring applies elastic force to the pressure plate, thereby fixing the winding drum to the fixed rod and preventing the winding drum from detaching from the fixed rod when winding the cable.

[0013] Preferably, a pin is inserted through the pressure plate, and the pin is rotatably inserted into both sides of the groove.

[0014] The above technical solution is adopted: a pin passes through the pressure plate, and the pin is inserted into both sides of the groove, so that the pressure plate can be rotatably mounted on the fixed rod.

[0015] Preferably, the anti-slip component includes a retaining strip fixed to one side of the fixing rod and a retaining groove formed along the axial direction of the winding drum.

[0016] The above technical solution avoids the problem that the fixed rod cannot rotate with the fixed rod by using an anti-slip component including a retaining strip fixed to one side of the fixed rod and a retaining groove opened along the axial direction of the winding drum.

[0017] Preferably, the size of the card slot is adapted to the size of the card strip.

[0018] The above technical solution is adopted to prevent slippage between the winding drum and the fixing rod by matching the size of the slot with the card strip.

[0019] Preferably, at least one card strip is provided, and at least one card slot is provided.

[0020] By adopting the above technical solution, at least one card strip is set and at least one card slot is opened, thus saving costs.

[0021] Preferably, an upper baffle is fixed to the top of the spool, and a lower baffle is fixed to the bottom of the spool, wherein the cross-sectional area of ​​the upper baffle and the lower baffle is larger than the cross-sectional area of ​​the spool.

[0022] The above technical solution is adopted: an upper baffle is fixed to the top of the winding drum, and a lower baffle is fixed to the bottom of the winding drum. The cross-sectional area of ​​the upper baffle and the lower baffle are both larger than the cross-sectional area of ​​the winding drum, so that the wire wound on the winding drum will not detach and unravel from both ends of the winding drum.

[0023] Preferably, a tray is fixed on the fixing rod, and the tray is used to support the winding drum.

[0024] The above technical solution is adopted: a tray is fixed on the fixing rod, and the tray is used to support the winding drum.

[0025] Compared with related technologies, this utility model has the following beneficial effects:

[0026] 1. Compared to traditional sewing thread winding mechanisms, this utility model incorporates a fixing component and an anti-slip component. In the initial winding stage, when the thread spool is placed on the fixing rod, two fingers press down on the pressure plate to make it vertical. With the other hand, holding the thread spool, the spool is slid off the fixing rod. As the spool descends, the spring force returns the pressure plate to a horizontal position, preventing the spool from detaching and flying off the fixing rod during winding. After winding, the spool can be easily removed from the fixing rod by lifting it upwards. Simultaneously, the anti-slip component prevents the spool from failing to rotate with the fixing rod. Therefore, the cooperation between the anti-slip component and the fixing component improves the working efficiency of the sewing thread winding mechanism compared to the traditional method of using bolts to fix the spool.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0034] Example 1

[0035] like Figures 1-5 As shown, a sewing thread winding mechanism includes a mounting shell 1, a drive gear 4 inside the mounting shell 1, a motor 2 at the bottom of the mounting shell 1, the output end of the motor 2 being fixedly connected to the drive gear 4, a driven gear 5 meshing with the drive gear 4, a fixing rod 6 fixed to the top of the driven gear 5, a thread winding drum 8 on the fixing rod 6, a fixing component 7 on the top of the fixing rod 6, and an anti-slip component 9 between the thread winding drum 8 and the fixing rod 6. The anti-slip component 9 prevents the thread winding drum 8 from sliding between the thread winding drum 8 and the fixing rod 6, and the fixing component 7 acts on the thread winding drum 8 to fix the thread winding drum 8 on the fixing rod 6.

[0036] An active gear 4 is installed inside the mounting housing 1. A motor 2 is installed at the bottom of the mounting housing 1. The output end of the motor 2 is fixedly connected to the active gear 4. A driven gear 5 is meshed with the active gear 4. A fixing rod 6 is fixed to the top of the driven gear 5. A winding drum 8 is installed on the fixing rod 6. A fixing component 7 is installed on the top of the fixing rod 6. An anti-slip component 9 is also installed between the winding drum 8 and the fixing rod 6 to prevent slippage between them. The fixing component 7 acts on the winding drum 8 to fix it to the fixing rod 6. In implementation, the motor 2 drives the active gear 4 to rotate, which in turn drives the meshing driven gear 5 to rotate. This causes the rotating rod on the driven gear 5 to rotate, which in turn drives the winding drum 8 to rotate, thus achieving the winding of the sewing thread by the winding drum 8. To solve the problem of the traditional bolt fixing method for the winding drum 8, which leads to... The problem of time-consuming disassembly and reduced efficiency of the thread winding mechanism is addressed by incorporating a fixing component 7 and an anti-slip component 9. In the initial stage of winding, when the thread spool 8 is placed on the fixing rod 6, two fingers are used to press the pressure plate 73 vertically. The other hand holds the thread spool 8 and slides it off the fixing rod 6. As the thread spool 8 is lowered, the spring force of the spring 72 returns the pressure plate 73 to a horizontal position, preventing the thread spool 8 from detaching and flying off the fixing rod 6 during winding. After winding, the thread spool 8 can be easily removed from the fixing rod 6 by lifting it upwards. Simultaneously, the anti-slip component 9 prevents the thread spool 8 from failing to rotate with the fixing rod 6. Therefore, the cooperation between the anti-slip component 9 and the fixing component 7 improves the working efficiency of the sewing thread winding mechanism compared to the traditional method of fixing the thread spool 8 with bolts.

[0037] Example 2

[0038] like Figures 1-5 As shown, the fixing component 7 includes a groove 71 opened at the top of the fixing rod 6. A fixing block 74 is fixed at the center of the top of the groove 71. Pressure plates 73 are hinged to both sides of the bottom of the groove 71. A spring 72 is provided between the fixing block 74 and the pressure plates 73. In the initial stage of winding, when the winding drum 8 is placed on the fixing rod 6, first press the pressure plate 73 with two fingers to make the pressure plate 73 vertical. Hold the winding drum 8 with the other hand and slide the winding drum 8 off the fixing rod 6. As the winding drum 8 is lowered... Under the elastic force of spring 72, the pressure plate 73 is brought back to a horizontal state, thus preventing the spool 8 from detaching from the fixing rod 6 and flying off during the winding process. Spring 72 is set at an angle, with one end of spring 72 fixedly connected to fixing block 74 and the other end of spring 72 away from fixing block 74 fixedly connected to pressure plate 73. Spring 72 applies elastic force to pressure plate 73, thereby fixing spool 8 to fixing rod 6 and preventing spool 8 from detaching from fixing rod 6 during winding.

[0039] A pin 75 passes through the pressure plate 73. The pin 75 is rotatably inserted into both sides of the groove 71, so that the pressure plate 73 can be rotatably mounted on the fixed rod 6. The anti-slip component 9 includes a retaining strip 91, which is fixed to one side of the fixed rod 6, and a groove 92 opened along the axial direction of the winding drum 8. This prevents the fixed rod 6 from rotating while the winding drum 8 cannot rotate with the fixed rod 6. The size of the groove 92 is adapted to the retaining strip 91 to prevent the winding drum 8 from sliding between the fixed rod 6.

[0040] At least one clip 91 and at least one slot 92 are provided to save costs. An upper baffle 81 is fixed to the top of the winding drum 8 and a lower baffle 82 is fixed to the bottom of the winding drum 8. The cross-sectional areas of the upper baffle 81 and the lower baffle 82 are both larger than the cross-sectional area of ​​the winding drum 8, so that the wire wound on the winding drum 8 will not detach and unravel from both ends of the winding drum 8. A tray 61 is fixed on the fixing rod 6, and the tray 61 is used to support the winding drum 8.

[0041] Example 3

[0042] To prevent damage to the internal structure of the mounting shell 1, a mounting cover 3 is provided on the top of the mounting shell 1. The mounting shell 1 and the mounting cover 3 can be installed and disassembled by bolts, which facilitates the maintenance of the internal mechanism of the mounting shell 1 in the future. Since the width of the clip 91 is the same as the width of the pressure plate 73, when the pressure plate 73 is pressed from both sides toward the fixing rod 6, the pressure plate 73 is made to be in a vertical state, which facilitates the installation and disassembly of the winding drum 8 on the fixing rod 6.

[0043] like Figure 5 As shown, in order to enable the spool 8 to be installed and removed from the fixing rod 6, one end of the pressure plate 73 is designed as an arc-shaped surface 76.

[0044] Working principle: such as Figures 1-5 As shown, in the initial stage of winding, when the spool 8 is placed on the fixed rod 6, first press the pressure plate 73 with two fingers to make the pressure plate 73 vertical. Hold the spool 8 with the other hand and slide the spool 8 off the fixed rod 6. As the spool 8 is lowered, the pressure plate 73 returns to a horizontal state under the elastic force of the spring 72, thus preventing the spool 8 from detaching from the fixed rod 6 and flying off during the winding process. After winding is complete, the spool 8 can be lifted upwards to remove it from the fixed rod 6. At the same time, the anti-slip component 9 prevents the spool 8 from not rotating with the fixed rod 6 when the fixed rod 6 rotates. Therefore, the cooperation between the anti-slip component 9 and the fixed component 7 improves the working efficiency of the sewing thread winding mechanism compared to the traditional method of fixing the spool 8 with bolts.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
