Description

Technical Field

[0001] This utility model relates to the field of fabric grading equipment technology, and in particular to a fabric grading machine swing arm drive device. Background Technology

[0002] During the operation of the fabric lining machine, the swing arm drive device plays a crucial role, and its performance directly affects the operating efficiency and stability of the fabric lining machine.

[0003] Early fabric stacking machines had relatively simple swing arm drive mechanisms with limited support and guidance methods for the swing arms. They typically used simple fixed brackets to mount guide wheels, making it difficult to adapt to the working requirements of swing arms of different sizes. This resulted in frequent adjustments or replacements of the equipment when faced with diverse production tasks, significantly reducing production efficiency and increasing production costs.

[0004] Meanwhile, traditional drive systems have significant shortcomings in the adjustment and fixing of guide wheels. Once the position of the guide wheels is determined, it is difficult to adjust them flexibly during operation. Even with simple adjustment structures, they often lack effective locking mechanisms. During equipment operation, the guide wheels are prone to self-deflection due to vibration, external forces, and other factors, leading to instability in the swing arm drive and consequently affecting the quality and neatness of the fabric stacking.

[0005] In terms of drive power transmission, the previous connection between the motor and the swing arm was rather crude, mostly using direct drive or simple gear drive, lacking precise speed change and buffering mechanisms. This not only resulted in a large load on the motor and shortened its service life, but also made it difficult to achieve smooth and precise control when driving the swing arm to swing, causing problems such as jamming and shaking to occur during the operation of the fabric lining machine, which could not meet the requirements of modern efficient and high-quality fabric lining production.

[0006] To address these issues, this utility model proposes a swing arm drive device for a fabric tying machine.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0016] By adopting the above technical solution, it is easy to control the synchronous rotation of two hollow worm gears on the same axis, thereby enabling the corresponding two support rods to deflect and providing stable support for the hollow worm gears.

[0017] A further feature of this invention is that the adjusting assembly also includes a synchronous belt and two synchronous pulleys. Synchronous pulleys are fixedly sleeved on both horizontal shafts, and the same synchronous belt is drivingly connected to the two synchronous pulleys.

[0018] By adopting the above technical solution, it is possible to ensure that the two horizontal axes rotate synchronously, thus facilitating the operator to adjust the two horizontal axes synchronously using either adjustment wheel.

[0019] A further feature of this invention is that the two hollow worms located on the same horizontal axis have opposite helical directions.

[0020] By adopting the above technical solution, it is possible to ensure that the two support rods rotate synchronously in opposite directions, thereby enabling the adjustment of the distance between two adjacent guide groove wheels.

[0025] The beneficial effects of this utility model are:

[0026] The support assembly provides effective support for the four guide rollers, while the adjustment assembly works in conjunction with the support assembly to adjust the relative positions of the four guide rollers. This allows the device to better adapt to swing arms of different sizes. The motor, gearbox, and linkage assembly controls the swing of the rotating plate. By adjusting the corresponding two guide rollers to move away from each other and placing them on either side of the rotating plate, it is easy to replace the guide rollers. Furthermore, the hollow worm and worm wheel design in the adjustment assembly maintains a self-locking state after adjustment, preventing the guide rollers from deflecting on their own during operation. This provides stable drive for the swing arm and enables stable swinging operation, improving the operating efficiency and stability of the fabric stacking machine. Attached Figure Description

[0035] Reference Figure 1-5A fabric tying machine swing arm drive device includes a frame 1, a rotating plate 2, four guide groove wheels 4 and a motor 22. The rotating plate 2 is rotatably mounted on the front side of the frame 1. The four guide groove wheels 4 are all rotatably mounted on the front side of the rotating plate 2 and are arranged in pairs. Four rotating shafts 31 arranged in parallel to each other are rotatably mounted on the rotating plate 2. Support rods 3 are radially fixedly mounted on the front end of each of the four rotating shafts 31. The four guide groove wheels 4 are all made of nylon and are rotatably mounted on the side of the corresponding support rods 33 near the rotating plate 2, which can provide effective support for the four guide groove wheels 4.

[0036] The rear ends of the four rotating shafts 31 extend to the rear side of the rotating plate 2 and are respectively fixedly fitted with worm gears 34. Four hollow worms 33 are provided on the rear side of the rotating plate 2, and each hollow worm 33 meshes with a corresponding worm gear 34. This allows the rotating shaft 31 to deflect at an angle when the worm rotates, thereby adjusting the distance between adjacent guide wheels 4. This enables the device to adapt well to the driving and guiding of fabric stacking machine swing arms of different sizes. Two parallel horizontal shafts 32 are rotatably mounted on the rear side of the rotating plate 2. Two hollow worms 33 located on the same axis are fixedly fitted onto the same horizontal shaft 32. One end of the horizontal shaft 32 extends to one side of the rotating plate 2 and is fixedly fitted with an adjusting wheel 35 for easy control. Two hollow worm gears 33 on the same axis are rotated synchronously, thereby enabling the corresponding two support rods 33 to deflect and providing stable support for the hollow worm gears 33. Synchronous pulleys 36 are fixedly sleeved on both horizontal shafts 32, and the same synchronous belt 37 is connected to the two synchronous pulleys 36 to ensure that the two horizontal shafts 32 are kept rotating synchronously. This allows the operator to adjust the two horizontal shafts 32 synchronously by adjusting either of the adjusting wheels 35. In order to ensure that the two support rods 33 keep rotating synchronously in opposite directions, the distance between the two adjacent guide groove wheels 4 can be adjusted. The two hollow worm gears 33 on the same horizontal shaft 32 have opposite helical directions.

[0037] A gearbox 21 is fixedly installed on one side of the frame 1. A motor 22 is fixedly installed on the rear side of the gearbox 21, and the output shaft of the motor 22 is connected to the input end of the gearbox 21. A support rod 23 is radially fixedly installed on the output end of the gearbox 21. A support rod 24 is radially rotatably installed on the support rod 23. A connecting rod is radially fixedly installed on the support rod 24, and the connecting rod is rotatably installed on the rotating plate 2, which can control the rotating plate 2 to swing, thereby controlling the swing arm set between the four guide groove wheels 4 to swing.

[0038] Specifically, in order to provide stable support for the horizontal shaft 32, two support bars 201 arranged in parallel to each other are fixedly installed on the rear side of the rotating plate 2. Both horizontal shafts 32 are rotatably mounted on the two support bars 201, and both horizontal shafts 32 and the two support bars 201 are arranged perpendicularly.

[0039] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0040] Working principle: First, turn on the power and place the swing arm between the four guide groove wheels 4. Then, rotate the corresponding horizontal shaft 32 by any one of the adjusting wheels 35. The rotation of the horizontal shaft 32 drives the hollow worm 33 to control the rotation of the worm wheel 34. Since the two hollow worms 33 located on the same horizontal shaft 32 have opposite spiral directions, the corresponding two rotating shafts 31 drive the corresponding support rods 3 to keep synchronous reverse deflection. At the same time, the synchronous pulley 36 and synchronous belt 37 can keep the two horizontal shafts 32 rotating synchronously, thereby controlling all four guide groove wheels 4 to contact the swing arm. In addition, it can also adapt well to swing arms of different sizes.

[0041] After the swing arm is installed, start the motor 22. The motor 22 controls the rotation of the first support rod 23 through the gearbox 21. At the same time, with the cooperation of the second support rod 24 and the connecting rod, it can control the rotating plate 2 to swing back and forth, thereby achieving stable drive of the swing arm.

[0042] When the guide groove wheel 4 needs to be disassembled, repaired, or replaced, rotate the adjusting wheel 35 in the opposite direction so that the support rod 33 deflects away from the installation position of the swing arm to the two sides of the rotating plate 2. Then, the guide groove wheel 4 can be disassembled, repaired, or replaced. After the disassembly, repair, or replacement is completed, it can be reset.
