Description

Technical Field

[0001] This utility model relates to the field of straightener technology, specifically to a steel cord straightener. Background Technology

[0002] In the steel cord manufacturing industry, after the steel cord is twisted, a straightener is needed to eliminate the internal stress of the steel wire, so that the steel cord remains straight and twisted stably.

[0003] The current straightener pressure rollers are set up with two sets, upper and lower. After the steel cord is pressed, the steel cord drives the pressure rollers to rotate. Because the bearings on the pressure roller shaft will be under great force after the steel cord is pressed, the bearings will have a short service life. Once the bearings are damaged, the pressure rollers will jam and stop rotating, resulting in defective products and a decrease in the pass rate. Utility Model Content

[0004] The purpose of this utility model is to provide a steel cord straightener. The technical problem to be solved is that during the straightening process of steel cord, it is necessary to press the steel cord through two sets of pressure rollers, which leads to a large force on the surface of the pressure roller shaft, which can easily cause bearing damage and seriously affect production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0006] A steel cord straightener includes a stationary slide plate with a first pressure roller on its surface.

[0007] A movable slide plate that moves relative to the stationary slide plate, wherein the side of the movable slide plate opposite to the stationary slide plate is provided with a second pressure roller;

[0008] The first pressure roller and the second pressure roller are both provided with eccentric grooves on their surfaces. The first pressure roller and the second pressure roller are arranged in an alternating manner, and the eccentric grooves between them form a straightening zone that provides for the movement of the steel cord.

[0009] Furthermore, the eccentric groove is positioned close to either the end face of the first pressure roller or the second pressure roller.

[0010] Furthermore, one side of the eccentric groove of the first pressure roller is connected to one end face of the first pressure roller;

[0011] One side of the eccentric groove of the second pressure roller is connected to one end face of the second pressure roller.

[0012] Furthermore, both the static slide plate and the dynamic slide plate are equipped with pressure roller shafts;

[0013] The first pressure roller is sleeved on the pressure roller shaft of the stationary slide plate;

[0014] The second pressure roller is mounted on the pressure roller shaft of the movable slide plate.

[0015] Furthermore, the pressure roller shaft uses nuts to fix the first pressure roller and the second pressure roller onto the moving slide plate and the stationary slide plate, respectively.

[0016] Furthermore, the side wall of the pressure roller shaft is fitted with a bearing.

[0017] Furthermore, a slider is engaged inside the movable slide plate, and the side wall of the slider is provided with a concave groove, through which the slider is engaged into the movable slide plate.

[0018] Furthermore, the sliders are configured as a plurality of sliders arranged in a linear array on the stationary slide plate along the direction of the steel cord arrangement.

[0019] Compared with the prior art, the technical solution provided by this utility model can achieve at least the following beneficial effects:

[0020] The steel cord straightener provided in this application improves the shape of the straightener pressure roller by reducing the width of the pressure roller on the surfaces of the moving and stationary slide plates through the eccentric groove. This reduces the dimension from the eccentric groove to the bearing, thereby reducing the stress on the bearing and extending its service life. Attached Figure Description

[0029] The technical solutions of this disclosure / application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure / application or its application or use.

[0030] It should be noted that, for the sake of clearer description, the terms "left side" and "right side" used in this application are based on the directions shown in the accompanying drawings. Example

[0031] like Figure 3 As shown, this embodiment provides a steel cord straightener, including a stationary slide plate 5 with a first pressure roller 1.1 on its surface, and a movable slide plate 7 that moves relative to the stationary slide plate 5. The movable slide plate 7 has a second pressure roller 1.2 on one side relative to the stationary slide plate 5.

[0032] The first pressure roller 1.1 and the second pressure roller 1.2 are both provided with eccentric grooves 9. The first pressure roller 1.1 and the second pressure roller 1.2 are arranged in an alternating manner and are connected by the eccentric grooves 9 to form a straightening zone that provides a straight line for the movement of the steel cord 8.

[0033] In this embodiment, the eccentric groove 9 is positioned close to the two end faces of the first pressure roller 1.1 or the second pressure roller 1.2, that is, the two inclined surfaces of the eccentric groove 9 are arranged such that their incident angles and reflection angles are not mutually equal; and one side of the two sides of the eccentric groove 9 is connected to one end face, that is, the end face of the first pressure roller 1.1 or the second pressure roller 1.2 is fitted with one side of the eccentric groove 9, thereby eliminating the original cylindrical surface position.

[0034] The stationary slide plate 5 is provided with a pressure roller shaft 2 inside, and the first pressure roller 1.1 is installed inside the pressure roller shaft 2; there are multiple pressure roller shafts 2, and they are arranged in a linear array on the surface of the stationary slide plate 5.

[0035] The portion of the pressure roller shaft 2 protrudes from the surface of the stationary slide plate 5. After the first pressure roller 1.1 and the second pressure roller 1.2 are fitted on it, the first pressure roller 1.1 and the second pressure roller 1.2 are fixed on the moving slide plate 7 and the stationary slide plate 5 respectively by the nut 4. The side wall of the portion of the pressure roller shaft 2 located inside the stationary slide plate 5 is fitted with a bearing 3, thereby providing a medium for the rotation of the pressure roller shaft 2.

[0036] The movable slide plate 7 is fitted with a slider 6. The side wall of the slider 6 is provided with a concave groove. The slider 6 is fitted into the movable slide plate 7 through the concave groove. Bearings 3 are installed at both ends of the slider 6, and pressure roller shafts 2 are installed inside. The first pressure roller 1.1 is mounted on the shaft and can rotate. The concave surfaces on both sides are fitted into the grooves of the movable slide plate 7 and can be adjusted up and down. After the first pressure roller 1.1 is adjusted to a suitable position, it can be combined with the second pressure roller 1.2 to apply the required pressure to the steel cord 8.

[0037] The sliders 6 are arranged in a linear array on the stationary slide plate 5 along the direction of the steel cord 8. One end of the pressure roller shaft 2 of the first pressure roller 1.1 is fixed by a nut 4. Example

[0038] like Figure 1 As shown, in the original technology, the straightener pressure rollers have two sets, namely the first pressure roller 1.1 and the second pressure roller 1.2. The first pressure roller 1.1 and the second pressure roller 1.2 are both mounted on the pressure roller shaft 2 and locked by the nut 4. The side wall of the pressure roller shaft 2 is equipped with a bearing 3. The two sets are mounted opposite each other on the stationary slide plate 5 and the slider 6, respectively. The slider 6 is mounted on the moving slide plate 7. Due to the opposite mounting, the distance from the center of the eccentric groove 9 on the surface of the stationary slide plate 5 or the slider 6 to the center of the eccentric groove 9 on the surface of the first pressure roller 1.1 or the second pressure roller 1.2 includes a 1.5mm inactive cylindrical surface, half of the eccentric groove and the gap. The distance from the center of the eccentric groove to the stationary slide plate 5 or the slider 6 is 5.5mm.

[0039] Furthermore, based on this embodiment, such as Figure 2 As shown, by removing one of the 1.5mm inactive cylindrical surfaces on each side of the pressure roller, the distance from the stationary slide plate 5 or slider 6 to the center of the eccentric groove can be reduced by 1.5mm, including only half of the eccentric groove and the gap. The distance from the center of the eccentric groove to the stationary slide plate 5 or slider 6 is reduced to 4mm, and the force on the bearing 3 on the pressure shaft is reduced by 27.3%.

[0040] like Figure 5 As shown, bearings 3 are installed at both ends of the slider 6, and pressure roller shaft 2 is installed inside. The first pressure roller 1.1 can rotate after being installed on the shaft. The concave surfaces on both sides are engaged in the grooves of the movable slide plate 7 and can be adjusted up and down. When the first pressure roller 1.1 is adjusted to a suitable position, the required pressure is applied to the steel cord 8.

[0041] like Figure 4 As shown, the first pressure roller 1.1 and the second pressure roller 1.2 of the straightener are mounted on the pressure roller shaft 2 and locked by the nut 4. The pressure roller shaft 2 is installed in the stationary slide plate 5 and the slider 6, and a bearing 3 is installed in cooperation. Multiple sliders 6 are mounted on the moving slide plate 7. The steel cord 8 is between the first pressure roller 1.1 and the second pressure roller 1.2 of the upper and lower sets.

[0042] Since the cylindrical surface of the pressure roller installed on the stationary slide plate 5 is eliminated, the position of the slider 6 can be reduced by 1.5mm towards the center of the eccentric groove; since the cylindrical surface of the pressure roller installed on the slider 6 is eliminated, the position of the stationary slide plate 5 can be reduced by 1.5mm towards the center of the eccentric groove; the diameter of the steel cord 8 is generally no more than 2mm, and the wheel groove can completely wrap the steel cord 8 without affecting the performance of the straightener. That is, the position of the bearing 3 installed in the stationary slide plate 5 and the slider 6 is reduced by 1.5mm. According to the lever principle, the force on the bearing 3 on the pressure shaft is reduced by about 27.3%. The pressure on the bearing 3 is reduced, which can effectively improve the overall life of the bearing 3.

[0043] In the description of this disclosure / application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. 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 communication between two components. Those skilled in the art will understand the specific meaning of the above terms in this disclosure / application based on the specific circumstances.

[0044] The above description is only a preferred embodiment of this application. 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 this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
