Technical Field

[0001] This utility model belongs to the technical field of knotting machines, and particularly relates to a knotting machine winding shaft assembly and a knotting machine. Background Technology

[0002] A bartacking machine, also known as a bartacking machine or knotting machine, is typically used to reinforce stitches. It is generally suitable for manufacturers of clothing, knitwear, sweaters, suits, and denim. The bartacking machine reinforces the seams at stress points, strengthens the ends of buttonholes, and helps to seal the top of buttonholes. During production, after buttons are attached, workers manually wrap thread around the back of the button several times to reinforce its strength. The bartacking machine can automate this process, shortening working time, increasing production efficiency, reducing worker fatigue, and saving manpower. With technological innovation, electronic bartacking machines have also emerged. The winding spool assembly is an indispensable component of the bartacking machine; it is used to wind long threads onto the spool.

[0003] However, existing technologies have some problems: the existing bar knotting machine winding shaft assembly is not easy to maintain. When people use the bar knotting machine winding shaft assembly, the disassembly steps are cumbersome, and when replacing the assembly, the assembly is difficult, time-consuming, labor-intensive, and affects work efficiency. Therefore, we propose a bar knotting machine winding shaft assembly and a bar knotting machine. Utility Model Content

[0025] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] like Figures 1 to 4 As shown, an embodiment of this utility model provides a winding shaft assembly, comprising:

[0027] The main body 1 of the knotting machine is provided with a winding base 2 at the upper end of the main body 1. A fixed column 3 is fixedly connected to the right side of the lower end of the winding base 2. A rotating swing arm 4 is sleeved on the surface of the fixed column 3. A fixed block 5 is fixedly connected to the rotating swing arm 4.

[0028] The actuating device 6 and the tensioning device 7 are located on the winding base 2. The actuating device 6 is used to rotate the rotating arm 4. The tensioning device 7 is located on the winding base 2. The tensioning device 7 is used to tension and limit the rotating arm 4.

[0029] Furthermore, a rotating shaft 8 is rotatably connected inside the rotating arm 4 and the fixed block 5. The upper end of the rotating shaft 8 extends to the winding base 2 and is fixedly connected to the winding shaft core 9. When winding, the wire wheel is first sleeved on the winding shaft core 9, and then the pressing rod 10 is moved. The surface of the pressing spring 11 on the pressing rod 10 will contact the surface of the wire wheel on the winding shaft core 9.

[0030] By setting the winding shaft core 9, the main body 1 of the knotting machine is made easier to fix the wire wheel during use, thus solving the problem that the main body 1 of the knotting machine is not easy to assemble the wire wheel during use.

[0031] Furthermore, the actuating device 6 includes a pin 61, a rotating seat 62 is rotatably connected to the surface of the pin 61, the upper end of the rotating seat 62 is fixedly connected to the lower end of the winding base 2, a stop 63 is sleeved on the lower end of the surface of the pin 61, a stop clip 64 is provided on the surface of the stop 63, and the stop clip 64 is fixedly connected to the fixing block 5. At the same time, actuating the pressing rod 10 will drive the pin 61 to start rotating, and the pin 61 drives the stop 63 to start oscillating through the rotating seat 62.

[0032] The pin 61 facilitates the replacement and maintenance of the stop 63 and the stop clip 64 during use, thus solving the problem that the stop 63 and the stop clip 64 are inconvenient to replace and maintain during use.

[0033] Furthermore, the upper end of the pin 61 is fixedly connected to a clamping rod 10 by an internal hex bolt. The clamping rod 10 is located above the winding base 2. A clamping spring 11 is fixedly connected to the clamping rod 10. The stop member 63 moves the stop clip 64 and presses against the surface of the stop clip 64.

[0034] The use of hex bolts facilitates the disassembly of pin 61 and clamping rod 10 during use, and makes it easy to replace and maintain clamping rod 10 when the pressure foot on clamping rod 10 is damaged.

[0035] Furthermore, a drive wheel 12 is fixedly connected to the lower end of the rotating shaft 8. A rubber ring 13 is fitted onto the surface of the drive wheel 12. An arc-shaped groove 14 is provided between the surface of the drive wheel 12 and the inside of the rubber ring 13. At this time, the stop clip 64 will drive the rotating arm 4 to rotate through the fixed block 5. The rotating arm 4 will drive the rotating shaft 8 to shift.

[0036] The arc-shaped groove 14 prevents the rubber ring 13 and the drive wheel 12 from slipping during use, thus preventing the rubber ring 13 and the drive wheel 12 from easily falling off during use.

[0037] Furthermore, the tensioning device 7 includes a fixed rod 71, and a tension spring 72 is provided on the surface of the fixed rod 71. One end of the tension spring 72 is engaged with an open hanging plate 73. The open hanging plate 73 is fixedly connected to the rotating swing arm 4 and makes the surface of the driving power wheel 12 contact the friction wheel driven inside the knotting machine body 1.

[0038] The cooperation of the fixing rod 71, the tension spring 72 and the perforated hanging plate 73 plays a role in fixing and stabilizing the rotating swing arm 4 during use, preventing the rotating swing arm 4 from rotating on its own during use.

[0039] Furthermore, assembly blocks 15 are fixedly connected to both sides of the surface of the winding base 2. The assembly block 15 is provided with a fixing wire 16 inside. The lower end of the fixing wire 16 is fixedly connected to the upper end of the knotting machine body 1. The fixing rod 71, tension spring 72, and perforated hanging plate 73 can tighten and limit the rotating swing arm 4 to prevent the rotating swing arm 4 from loosening or displacing.

[0040] The cooperation between the fixing wire 16 and the assembly block 15 facilitates the disassembly of the winding base 2 and the main body 1 of the knotting machine during use, reduces the disassembly time of the winding base 2 during maintenance, and allows for faster maintenance of the winding base 2.

[0041] A knotting machine, comprising:

[0042] The main body 1 of the knotting machine has an installation groove on one side of its upper end, and the installation groove is fixedly connected to the winding base 2.

[0043] The installation slot facilitates the disassembly and assembly of the main body 1 of the knotting machine and the winding base 2 during use, solving the problem that the main body 1 of the knotting machine and the winding base 2 are inconvenient to disassemble during use.

[0044] 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.
