[0002] Steel cord has a wide range of industrial applications, especially in the carcass material of automobile tires. Backing defects are an important indicator of steel cord quality. Steel cord produced by various stranding machines in our company requires inspection for backing defects. Backing protection is a crucial device for detecting backing defects in steel cord. However, due to the diversity of stranding machine models, including left-hand and right-hand machines with inconsistent directions, there are various methods for backing protection. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a composite back-thread protection device that is easy to use with various machine models, reduces the types of spare parts, ensures the uniformity and flexible allocation of equipment tooling, and reduces production costs.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] In a first aspect, this utility model provides a composite backing yarn protection device, comprising:

[0006] Backing wire protection base, wherein the backing wire protection base has openings of the same size on the left and right sides;

[0007] The P-type plate is rotatably mounted in the opening of the back thread protection base via bearings and pins. The P-type plate can be flipped by rotation and switched between the left and right openings.

[0008] A fixed detection piece is fixedly installed on the back wire protection base;

[0009] The movable detection piece is mounted on the P-type plate and cooperates with the fixed detection piece to detect the cord. When the P-type plate is flipped, the movable detection piece can move accordingly.

[0010] The copper pillars are located on both sides of the left and right openings and come into contact with the movable detection plate when the P-type plate flips to the set position, triggering the stop mechanism of the left and right machine tools.

[0011] Furthermore, the device also includes a strong magnet, which is mounted on the back wire protection base and flush with the left and right openings, and attracts the movable detection piece when the movable detection piece is in the detection position.

[0012] Furthermore, the device also includes a bracket, which is disposed on both sides of the left and right openings for supporting and fixing the back wire protection base, the P-type plate, and the copper column.

[0013] Furthermore, the device also includes a nylon insulating pad, through which the copper pillar is mounted on the bracket.

[0014] Furthermore, a semi-circular hole is provided on the contact side of both the fixed detection piece and the movable detection piece. The semi-circular holes of the fixed detection piece and the movable detection piece cooperate with each other to detect whether there is back yarn in the cord.

[0015] Furthermore, both the fixed detection piece and the movable detection piece are made of metal alloy.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0022] like Figure 1 As shown in the figure, this embodiment introduces a composite backing yarn protection device, including: a backing yarn protection base 1, a P-shaped plate 2, a bearing, a pin, a strong magnet 5, a fixed detection plate 6, a movable detection plate 7, a bracket 8, a nylon insulating pad 9, and a copper column 10; the backing yarn protection base 1 has openings of equal size on its left and right sides; the P-shaped plate 2 is rotatably disposed in the opening of the backing yarn protection base 1 through the bearing and the pin, and the P-shaped plate 2 can be flipped by rotation, switching between the left and right openings; the fixed detection plate 6 is fixedly installed on the backing yarn protection base 1; the movable detection plate 7 is installed on the P-shaped plate 2 and cooperates with the fixed detection plate 6 for detecting the cord, and the movable detection plate 7 can move accordingly when the P-shaped plate 2 is flipped; the strong magnet 5 is installed on the backing yarn protection base 1 and is flush with the left and right openings, and is used for detecting the cord when the movable detection plate 7 is flipped. When the plate 7 is in the detection position, it is attracted to the movable detection plate 7; the copper pillar 10 is set on both sides of the left and right openings and contacts the movable detection plate 7 when the P-type plate 2 is flipped to the set position, triggering the stop mechanism of the left and right machine tools; the bracket 8 is set on both sides of the left and right openings to support and fix the back-filament protection base 1, the P-type plate 2 and the copper pillar 10; the copper pillar 10 is installed on the bracket 8 through the nylon insulating pad 9; the contact surfaces of the fixed detection plate 6 and the movable detection plate 7 are both provided with semi-circular holes, and the semi-circular holes of the fixed detection plate 6 and the movable detection plate 7 cooperate with each other to form a circular hole with a diameter larger than the diameter of the qualified steel cord but smaller than the diameter of the circumscribed circle of the steel cord cross-section when back-filament occurs, which is used to detect whether there is back-filament in the cord; the fixed detection plate 6 and the movable detection plate 7 are both made of metal alloy.

[0023] In this embodiment, the back-thread protection is redesigned by making the back-thread protection base 1 have equal openings on both sides. A P-shaped plate 2 is designed so that the left and right openings can be flipped interchangeably. Bearings and pins are installed inside the P-shaped plate 2. A strong magnet 5 is installed on the back-thread protection base, making the strong magnet flush with the left and right openings. A fixed detection piece 6 is installed on the back-thread protection base 1, and a movable detection piece 7 is installed on the P-shaped plate 2. At the same time, a universal bracket 8 is made for both left and right sides, and a nylon insulating pad 9 and a copper pillar 10 are installed. When the P-shaped plate 2 falls down, the movable detection piece 7 touches the copper pillar 10, and the machine tool stops. Because the left and right openings are equal, this back-thread protection device is applicable to both left and right handpieces.

[0024] This embodiment provides a composite back-fiber protection device, which triggers the stop mechanism of the left and right machine tools by rotating the movable detection piece 7 driven by the P-type plate 2. This facilitates the use of various machine models, reduces the types of spare parts, ensures the uniformity and flexible allocation of equipment tooling, and reduces production costs.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
