Description

Technical Field

[0001] This invention belongs to the field of textile machinery technology, and specifically relates to an upper yarn-pulling needle device for a top rod type heddle threading machine driven by a wheel. Background Technology

[0002] As a new type of highly automated warp threading equipment, the automatic heddle threading machine has gradually been applied to some high-quality enterprises in recent years. Its speed and threading quality contrast sharply with the traditional manual threading, meeting the development needs of the modern textile industry. The yarn-pulling assembly is a crucial component of the automatic heddle threading machine; its reliability and sensitivity determine the machine's efficiency and threading quality. Currently, existing heddle threading machines can only pull yarn from one area during the threading process. Due to the large and dense area of ​​the yarn, pulling yarn from only one area during the process can result in some yarns not being pulled or not being pulled at all, leading to low threading efficiency. Summary of the Invention

[0003] This invention provides a top-pulling needle device for a pulley-driven top rod type heddling machine that features stable structure, multi-angle heddling, and high heddling efficiency.

[0004] A top-rod type heddle threading machine with pulley drive has an upper yarn-pulling needle device. The upper yarn-pulling needle device includes a motor base, a motor device and a cylinder device connected to one side of the motor base, and a rocker arm device connected to the cylinder device. A pulley device is connected to the other side of the motor base, and a slider device is connected to the pulley device. A lever is connected to the rocker arm device and the slider device. The motor device drives the slider device connected to the pulley device to move laterally, and the cylinder device drives the rocker arm device to move longitudinally.

[0005] The motor assembly includes a motor and a motor shaft, and a heat sink is provided on the outer periphery of the motor. The heat sink dissipates heat from the motor.

[0006] The cylinder assembly includes a cylinder body connected to a cylinder mounting base. A second buffer pad is provided at one end of the cylinder mounting base near the cylinder body. A connecting rod is located within the cylinder mounting base, with a concave crank pin connected to one end of the connecting rod. A first buffer pad is provided between the concave crank pin and the connecting rod. A third copper sleeve is fitted around the connecting rod and the concave crank pin. The rocker arm assembly includes a rocker arm radially connected to the connecting rod via a positioning shaft. A lever is axially connected to the rocker arm. A first copper sleeve is fitted at the connection between the lever and the rocker arm. Second copper sleeves are fitted at both ends of the positioning shaft. The rocker arm assembly and the cylinder assembly enable the lever to move up and down.

[0007] The pulley device includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The first synchronous pulley mates with the motor shaft, and the second synchronous pulley mates with a bearing assembly. The bearing assembly includes a pin, a bearing housing, and a bearing cover. A bushing is fitted onto the pin, and bearings are fitted at both ends of the bushing. The slider device is located above the pulley device. The pulley device includes a linear guide rail, a slider, and a connecting seat. The linear guide rail is connected to the motor housing. The bottom of the connecting seat is connected to the synchronous belt, and the middle of the connecting seat is connected to the slider. A handle shaft is radially connected to the top of the connecting seat. The handle shaft includes a handle head and a shaft body. Fourth copper sleeves are fitted at both ends of the shaft body, and a lever is axially connected to the handle head. By using the pulley device and the slider device, and applying the lever principle, the fulcrum of the lever is changed, thereby changing the direction of the lever's movement.

[0008] The motor base is connected to a mesh cover via positioning screws. The mesh cover protects the internal parts of the threading machine.

[0009] The motor is a coreless motor. Coreless motors have outstanding energy-saving characteristics, sensitive and convenient control characteristics, and stable operation characteristics, demonstrating significant technological advancement. They serve as highly efficient energy conversion devices.

[0010] The technical effects of this invention are as follows:

[0011] By cooperating with the pulley device and the slider device, the fulcrum of the yarn-pulling rod is moved laterally. By cooperating with the cylinder device and the swing arm device, the yarn-pulling rod is moved up and down, thereby realizing the yarn-pulling rod to pass through the heddles at multiple angles, improving the yarn-pulling range and yarn-pulling efficiency.

[0020] To prevent the motor from overheating and causing malfunctions, the motor assembly includes a motor 1 and a motor shaft 11, with a radiator 12 provided on the outer periphery of the motor 1.

[0021] The cylinder assembly includes a cylinder body 91, a cylinder mounting base 92 connected to the cylinder body 91, a second buffer pad 94 provided at one end of the cylinder mounting base 92 near the cylinder body 91; a connecting rod 81 is provided inside the cylinder mounting base 92, a concave crank pin 95 is connected to one end of the connecting rod 81, a first buffer pad 93 is provided between the concave crank pin 95 and the connecting rod 81; a third copper sleeve 86 is fitted on the outside of the connecting rod 81 and the concave crank pin 95.

A first copper sleeve 84 is fitted at the connection between the lever 7 and the rocker arm 82. Second copper sleeves 85 are fitted at both ends of the positioning shaft 83.

[0023] The pulley device includes a first synchronous pulley 4, a second synchronous pulley 5, and a synchronous belt 41. The first synchronous pulley 4 is engaged with the motor shaft 11, and the second synchronous pulley 5 is engaged with the bearing assembly. The bearing assembly includes a pin 55, a bearing seat 52, and a bearing cover 51. A bushing 54 is fitted on the pin 55, and bearings 53 are fitted at both ends of the bushing 54.

[0024] The slider device is located above the pulley device. The pulley device includes a linear guide rail 61, a slider 62, and a connecting seat 65. The linear guide rail 61 is connected to the motor base 2. The bottom of the connecting seat 65 is connected to the synchronous belt 41.

[0027] The working principle of this invention is as follows: the rocker arm device is driven to move up and down by the cylinder device. While the rocker arm device moves up and down, it drives one end of the lever (7) to move up and down. Then, the first synchronous wheel (4) is driven to rotate by the motor (1), which drives the synchronous belt (41) and the second synchronous wheel (5) to move laterally. The movement of the synchronous belt (41) drives the slider (62) connected to the connecting seat (65) to move laterally on the linear guide rod (61). At the same time, the movement of the connecting seat (65) will cause the handle shaft (63) to move laterally on the lever (7). Therefore, the fulcrum of the lever (7) is moved, thereby realizing the multi-angle movement of the lever (7).
