Description

Technical Field

[0001] This utility model relates to the technical field of rope twisting machine devices, specifically to a rope twisting machine power failure prevention rope breakage device. Background Technology

[0002] A rope twisting machine is a key piece of equipment used to twist multiple strands of fiber or thread into ropes. During operation, the winch rotates, causing the thread to wind and twist, while the pressure rollers apply appropriate pressure to the thread through contact with the winch to ensure twisting quality and rope formation stability. However, in actual production, rope twisting machines often experience sudden power outages (such as power line failures or equipment overload protection), causing the winch to stop operating abruptly. If the pressure rollers on the thread are not released in time, the thread is prone to breakage due to excessive instantaneous force under the inertial force of the winch and the continuous pressure of the pressure rollers. This not only wastes raw materials and interrupts production but also increases the difficulty of cleaning before restarting the equipment due to the tangling and scattering of broken thread, affecting production efficiency. Traditional rope twisting machine pressure roller drive devices mostly rely on continuously powered power components (such as cylinders) to maintain pressure, lacking an automatic pressure relief mechanism in case of power failure, making it difficult to avoid the aforementioned rope breakage problem. Therefore, there is an urgent need for a device that can quickly release pressure on the pressure roller and prevent rope breakage in case of power failure. Moreover, unexpected power outages often cause the main machine and the take-up machine to be out of sync, resulting in a shortened steel rope pitch or breakage, producing scrap. Resuming production is time-consuming and labor-intensive, affecting efficiency, and in severe cases, it can cause damage to equipment and tooling. This patent can avoid the occurrence of this problem. Utility Model Content

[0003] Technical problems to be solved In view of the above-mentioned shortcomings of the existing technology, the present invention provides a rope twisting machine power failure prevention rope breakage device, which can effectively solve the problems in the existing technology.

[0004] Technical solution This utility model provides a power failure prevention device for a rope twisting machine, including a winch. One end of the winch is in contact with a pressure roller. Both sides of the pressure roller are rotatably connected to a base via a bracket. A crossbar is fixed in the middle of the bracket, and a sleeve rod is sleeved on the outside of the crossbar. The end of the sleeve rod is fixedly connected to the output head of a cylinder. The tail end of the cylinder is rotatably connected via a connecting seat. One end of the cylinder is electrically connected to an external control device via a solenoid valve.

[0005] Furthermore, the front end of the sleeve is a ring structure, and the middle part of the sleeve is sleeved on the outside of the crossbar.

[0006] Furthermore, the two ends of the base and the two sets of brackets are connected by pins, and the two ends of the pressure roller are sleeved between the brackets.

[0007] Furthermore, the top end of the connecting seat and the tail end of the cylinder are rotatably connected by a pin.

[0008] Furthermore, the terminals of the solenoid valve are electrically connected to the AC220V power supply output from the primary main power supply line L1 and line N.

[0009] Furthermore, a soft plastic ring is fitted onto the surface of the pressure roller.

[0010] Beneficial effects In this invention, the main power supply line L1 and line N of the equipment are connected to AC220V to power the solenoid valve at the winch that can activate the pressure roller. When the solenoid valve is energized, it is in the state of cutting off the air supply. This solenoid valve is constantly powered along with line L1, so that the pressure roller is separated from the winch. When line L1 is unexpectedly de-energized, that is, when the solenoid valve is de-energized, it instantly switches from the air-cut state to the air-open state. This can brake the main unit to stop the main unit as soon as possible and activate the pressure roller cylinder to press the pressure roller onto the winch. This increases the friction coefficient between the steel rope and the winch, so that the steel rope can be pulled out smoothly by the winch, avoiding problems such as over-twisting of the steel rope caused by power failure.

[0011] In this device, the solenoid valve is connected to the main power supply. When a sudden power outage occurs, the solenoid valve loses power and triggers the cylinder to actuate. Through the sleeve rod, bracket, and other structures, the pressure roller is driven to quickly disengage from the winch, promptly relieving pressure on the rope and preventing rope breakage due to winch inertia and continuous pressure. This reduces material waste and production interruption. The automatic pressure relief mechanism during power outages prevents problems such as wire tangling and scattering after rope breakage, reducing the difficulty of cleaning before restarting the equipment, facilitating rapid production recovery, and improving production efficiency. The pressure roller is rotatably connected to the base via the bracket. The sleeve rod's fit with the bracket's crossbar and the cylinder's rotatable connection with the connecting seat ensure the flexibility and stability of the pressure roller's movement. The soft plastic ring on the surface of the pressure roller enhances its fit with the rope to ensure normal twisting quality and reduces hard wear on the rope, improving the quality of the finished rope. The device is connected to external control equipment and the main power supply via the solenoid valve. It has a simple structure, is easy to integrate with existing rope twisting machines, requires no large-scale modification to the main body of the equipment, and has a wide range of applications.

Figure 1 - Appendix Figure 3 The system includes a winch 1, one end of which contacts a pressure roller 2.

One end of the cylinder 3 is electrically connected to an external control device via a solenoid valve 4. The solenoid valve 1 is connected to a primary power supply.

The pressure roller 2 is rotatably connected to the base 23 through the bracket 21, and the sleeve rod 22 is sleeved and matched with the crossbar of the bracket 21 and the cylinder 3 is rotatably connected to the connecting seat 32, ensuring the flexibility and stability of the pressure roller 2's movement; the soft plastic ring on the surface of the pressure roller 2 can enhance the fit with the rope to ensure normal twisting quality, and reduce hard wear on the rope, improving the quality of the finished rope. The device is connected to the external control equipment and main power supply through the solenoid valve 1. The structure is simple, easy to integrate with existing rope twisting machines, does not require large-scale modification of the main body of the equipment, and has a wide range of applications.

[0019] The top of the connecting seat 32 and the tail of the cylinder 3 are rotatably connected by a pin; the wiring terminal of the solenoid valve 4 is electrically connected to the AC220V power supply output from the primary main power supply line L1 and N; the AC220V power supply output from the primary main power supply line L1 and N is used to power the solenoid valve at the winch that can activate the pressure roller; when the solenoid valve is energized, it is in the state of cutting off the air supply, and this solenoid valve is constantly powered along with the L1 line, so that the pressure roller is separated from the winch; when the L1 line is unexpectedly de-energized, that is, when the solenoid valve is de-energized, it instantly switches from the air-cut state to the air-open state, which can brake the main unit to stop the main unit as soon as possible, and activate the pressure roller cylinder to press the pressure roller onto the winch, increasing the friction coefficient between the steel rope and the winch, so that the steel rope can be pulled out smoothly by the winch, avoiding problems such as over-twisting of the steel rope caused by power failure.
