Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, and in particular to a novel spindle drive structure for a twisting machine. Background Technology

[0002] In the field of yarn twisting machines in the textile industry, the spindle transmission components of existing domestic and foreign twisting machines are driven by four different methods.

[0003] The first type is a roller-belt drive system. A motor drives a main shaft that connects to multiple long shafts. Each long shaft has several rollers mounted on it, and each roller drives four spindles via a belt. A complex tensioning device adjusts the belt tension for every four spindles. Its advantages and disadvantages are: this structure is primarily energy-saving, but due to the large number of transmission components and complex structure, installation and maintenance are extremely inconvenient, and the low spindle speed results in low efficiency.

[0004] The second type is the belt-driven collective drive, where a motor drives a long belt to frictionally drive all the spindles. Each or two spindles have a tensioning roller to adjust the tension between the belt and the spindle. Its advantages and disadvantages are: this structure is easy to install and maintain, but the friction drive generates excessive noise, consumes a lot of electricity, and has a low spindle speed, resulting in low efficiency.

[0005] The third type: motor-driven spindles, where the main shaft of the motor drives the spindles, with each spindle corresponding to one motor. Its advantages and disadvantages are: high manufacturing costs leading to high customer purchase prices and low cost-effectiveness; and the motor and spindle being integrated, resulting in a relatively high machine height and inconvenience for employees to operate.

[0006] The fourth type involves a motor-connected spindle, with each spindle driven by a single motor via a transmission belt. Its advantages and disadvantages are: high manufacturing costs leading to high customer purchase prices and low cost-effectiveness. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a novel spindle drive structure for a twisting machine. This structure is simple, easy to install and maintain, has low manufacturing cost, is energy-saving, and operates at high speed and low noise.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A novel spindle drive structure for a twisting machine includes a fixed plate, a motor plate, spindle plates, and a spring assembly. Two tensioning rollers are positioned above the fixed plate and connected to it via shafts. Two rows of opposing sliding guide blocks are arranged on the fixed plate on one side of the tensioning rollers. The motor plate is slidably positioned between the two rows of sliding guide blocks. A motor is fixed below the motor plate, and a motor pulley is positioned above it. An opening is provided on the fixed plate for the motor to pass through and move. Two spindle plates are located on either side of the fixed plate, and several spindles are mounted on each plate. The motor pulley, the tensioning rollers, and the spindles are connected via a belt drive. The spring assembly connects the fixed plate and the motor plate, applying a force to the motor plate away from the tensioning rollers. The motor drives the motor pulley to rotate, and through the belt drive, the tensioning rollers and spindles rotate synchronously. The spring assembly maintains the tension of the belt, prevents slippage, suppresses vibration and noise, maintains the stability of the transmission system, and distributes the load to extend the life of the transmission components.

[0010] Preferably, each of the two ingot plates has two ingots, and the ingots on the two ingot plates are arranged in a 2*2 matrix. One motor drives four ingots, and the ingot belt transmission path is U-shaped.

[0011] Preferably, the friction surface of the spindle belt on the motor pulley is opposite to the friction surface of the tensioning wheel and the spindle.

[0012] Preferably, the spring assembly is a tension spring assembly, including a tension spring, a first tension spring connector fixed to the fixed plate, and a second tension spring connector fixed to the motor plate. The two ends of the tension spring are respectively connected to the first tension spring connector and the second tension spring connector. The first tension spring connector is located on the side of the fixed plate away from the tension wheel, and the two ends of the tension spring are hooks, applying tension to the second tension spring connector to keep the motor plate moving away from the tension wheel.

[0013] Preferably, one end of the tension spring is connected to a screw, which passes through the first connecting member of the tension spring and is threadedly connected to a nut. The tension of the tension spring is adjusted by the nut and the screw, thereby adjusting the movement of the motor plate, the motor on it, and the motor pulley, ultimately achieving the purpose of adjusting the tension of the belt.

[0014] Preferably, the spring assembly is a compression spring assembly, including a compression spring, a first compression spring connector fixed to the fixed plate, and a second compression spring connector fixed to the motor plate. The two ends of the compression spring abut against the first and second compression spring connectors, respectively. The first compression spring connector is located on the fixed plate near the tension wheel, and the compression spring applies a thrust to the second compression spring connector, causing the motor plate to tend to move away from the tension wheel.

[0015] Preferably, the compression spring assembly further includes a guide rod, one end of which is connected to the first connecting member of the compression spring, and the other end of which passes through the second connecting member of the compression spring and is slidably connected thereto. The compression spring is sleeved on the guide rod. The guide rod serves to limit and guide the compression spring and the motor plate.

[0016] Preferably, one end of the guide rod is provided with a screw section, which passes through the first connecting member of the compression spring and is threadedly connected to the adjusting nut. The tension of the compression spring is adjusted by adjusting the nut and the screw section, thereby adjusting the movement of the motor plate, the motor on it, and the motor pulley, ultimately achieving the purpose of adjusting the tension of the belt.

[0017] Preferably, the spring assembly includes both the tension spring assembly and the compression spring assembly described above.

[0018] The beneficial effects of this utility model are as follows: a new type of drive component consisting of four spindles driven by a single motor through a spindle belt, with the motor installed between two spindle plates and the tension adjusted by a spring assembly, has the advantages of high speed and low noise, simple structure, convenient installation and maintenance, low manufacturing cost, energy saving and high cost performance.
