Description

Technical Field

[0001] The invention relates to the technical field of twisting machines, in particular to a novel spindle driving structure of a twisting machine. Background Art

[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 driving modes.

[0003] The first type is the roller-belt drive, where a motor drives a main shaft connected to multiple long shafts. Each long shaft is equipped with several rollers, each of which drives four spindles through a spindle belt. Every four spindles are equipped with a complex tensioning device to adjust the tension of the spindle belt. Its advantages and disadvantages are: this structure mainly saves electricity, but due to the large number of transmission components and complex structure, it is extremely inconvenient to install and maintain, and the spindle speed is low and the efficiency is low.

[0004] The second type: a tangential belt collective drive. A motor drives a long tangential belt through friction, driving all the spindles. A set of tensioning rollers adjusts the tension between the belt and the spindles for every one or two spindles. Its advantages and disadvantages include: This structure is easy to install and maintain, but the friction drive generates excessive noise, high power consumption, and low spindle speed, resulting in low efficiency.

[0005] The third type: motor spindles, where the motor's main shaft acts as the spindle drive, with each spindle corresponding to a motor. Its advantages and disadvantages include: high manufacturing costs, resulting in high prices for customers, a low cost-performance ratio, and the fact that the motor and spindle are integrated, making the machine relatively tall and inconvenient for employees to operate.

[0006] The fourth type: the motor is connected to the spindle, and the motor drives the spindle one by one. Each spindle is driven by a motor through a transmission belt. Its advantages and disadvantages are: the manufacturing cost is too high, resulting in high customer purchase prices and low cost performance. Summary of the Invention

[0007] The purpose of the present invention is to solve the deficiencies of the above-mentioned prior art and provide a new spindle drive structure for a twisting machine, which has a simple structure and is easy to install and maintain, has a low manufacturing cost, saves energy and electricity, and has high speed and low noise.

[0008] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A novel spindle drive structure for a twisting machine comprises a fixed plate, a motor plate, a spindle plate, and a spring assembly. Two tensioning pulleys are mounted above the fixed plate, connected to the fixed plate via a shaft head. Two rows of opposing sliding guide blocks are mounted on the fixed plate on one side of the tensioning pulleys. The motor plate is slidably mounted between the two rows of sliding guide blocks. A motor is mounted below the motor plate, and a motor pulley is mounted above the motor plate. The fixed plate includes openings for the passage and translation of the power supply motor. There are two spindle plates, located on either side of the fixed plate, and several spindles are mounted on the spindle plates. The motor pulleys, tensioning pulleys, and spindles are connected via a spindle belt transmission. The spring assembly is connected to the fixed plate and the motor plate, respectively, applying a force to the motor plate away from the tensioning pulleys. The motor drives the motor pulleys to rotate, and through the spindle belt transmission, the tensioning pulleys and spindles rotate synchronously. The spring assembly maintains tension in the spindle belt, preventing slippage, suppressing vibration and noise, maintaining transmission system stability, and evenly distributing the load to extend the life of transmission components.

[0009] Preferably, there are two spindles on each spindle plate, and the spindles on the two spindle plates are distributed in a 2*2 matrix. Four spindles are driven by one motor, and the spindle belt transmission path is in a "concave" shape.

[0010] 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.

[0011] Preferably, the spring assembly is a tension spring assembly, comprising a tension spring, a first tension spring connector fixed to the fixed plate, and a second tension spring connector fixed to the motor plate, with the first and second tension spring connectors connected at both ends of the tension spring, respectively. The first tension spring connector is located on a side of the fixed plate away from the tensioning pulley, and the tension spring has hooks at both ends that apply tension to the second tension spring connector to maintain a tendency for the motor plate to move away from the tensioning pulley.

[0012] 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 tightness of the tension spring is adjusted by the nut and the screw, thereby adjusting the ingress and egress of the motor plate, the motor thereon, and the motor pulley, thereby ultimately achieving the purpose of adjusting the tightness of the spindle belt.

[0013] Preferably, the spring assembly is a compression spring assembly, comprising a compression spring, a first compression spring connector fixed to the fixed plate, and a second compression spring connector fixed to the motor plate, with the ends of the compression spring respectively abutting against the first compression spring connector and the second compression spring connector. The first compression spring connector is located on a side of the fixed plate proximate to the tensioning pulley, and the compression spring applies a thrust to the second compression spring connector to maintain a tendency for the motor plate to move away from the tensioning pulley.

[0014] Preferably, the compression spring assembly further comprises a guide rod, one end of which is connected to the first connector of the compression spring, and the other end of which passes through the second connector of the compression spring and is slidably connected thereto, and the compression spring is sleeved on the guide rod. The guide rod serves to limit and guide the compression spring and the motor plate.

[0015] Preferably, a screw segment is provided at one end of the guide rod, which passes through the first connector of the compression spring and is threadedly connected to an adjusting nut. The tightness of the compression spring is adjusted by adjusting the nut and the screw segment, thereby adjusting the entry and exit of the motor plate, the motor thereon, and the motor pulley, and ultimately achieving the purpose of adjusting the tightness of the spindle belt.

[0016] Preferably, the spring assembly includes both the tension spring assembly and the compression spring assembly described above.

[0017] The beneficial effects of the present invention are: a new driving component with four spindles in a group is driven by a motor through a spindle belt. The motor is installed in the middle of the two spindle plates and the tension is adjusted by a spring assembly. It has the advantages of high speed and low noise, simple structure, easy installation and maintenance, low manufacturing cost, energy saving and power saving, and high cost performance.
