Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of metal surface treatment, and particularly relates to a feeding separation roller for steel wire treatment. BACKGROUND

[0002] After the steel wire is produced, rusting usually occurs in the stage of waiting for sale or the stage of waiting for use after being sold, and in order to prevent the rusting from affecting the subsequent use, the rusting needs to be treated.

[0003] The patent No. CN201921667151.7 discloses a scheme for completely treating the rust on the surface of the steel wire. Since the flat brushing mode of the traditional scale breaker roller can only treat the upper and lower surfaces of the steel wire, the left and right sides of the steel wire cannot be treated, and there is a dead angle. In the file, the steel wire is twisted by the angle through the upper and lower arrangement of the deflection roller, and then the steel wire is obliquely brushed through the first steel wire rust removal machine, and then the steel wire is flatly brushed through the second steel wire rust removal machine, so that the rust removal treatment of the steel wire is completed through the combination of flat brushing and oblique brushing.

[0004] However, before the multiple steel wires are introduced into the steel wire rust removal device, the steel wires need to be kept at uniform intervals and parallel to each other, otherwise the steel wires cannot be correspondingly introduced into the guide grooves of each deflection wheel on the deflection roller, and the steel wires cannot be twisted, so that the complete treatment effect cannot be achieved. The patent No. CN201921668327.0 discloses a feeding machine of a steel wire rust removal production line, which can guide the steel wires to the same height and parallel to each other. The separation roller adopts a special bearing shell matched with a standard bearing, and is formed by press fitting. Multiple annular groove-shaped roller ways are uniformly arranged on the surface of the separation roller. In use, two separation rollers are usually arranged in an upper and lower arrangement and used in cooperation. The roller ways of the two separation rollers are matched one by one. After the one end of the multiple steel wires respectively passes through the corresponding cross-shaped wheel set mechanism and the tension pulling mechanism, the steel wires are guided to the corresponding roller ways at the same height and parallel to each other.

[0005] Since the running speeds of the steel wires are different, and the roller ways are synchronously rotated, the steel wires passing through the roller ways will be scratched due to the difference in the running speeds, and the quality of the steel wires is affected. In the subsequent use improvement, multiple separation wheels with guide grooves are integrated on a fixed shaft, and each separation wheel can rotate around the fixed shaft through a bearing. Since the separation wheels are of the same size, the guide grooves are located at the same height. In order to prevent the adjacent separation wheels from being synchronously rotated, a plurality of Figure 5As shown, the annular grooves capable of accommodating the balls are arranged at the corresponding positions of the opposite faces of the adjacent separation wheels, and the balls are partially arranged in the left and right annular grooves, so that the left and right separation wheels are kept at a preset interval, and the interval is 0.5-1.5 mm, so that the differential rotation between the separation wheels can be formed, and when the travel speeds of the steel wires are different, the separation wheels can cooperate with the travel speeds of the steel wires, and the abrasion of the steel wires can be avoided.

[0006] However, the problem is that the wear between the grooves and the balls occurs after a period of work, so that the width of the groove is increased, the balls originally uniformly distributed along the circumferential direction of the groove cannot play a role in the adjacent separation wheels, and the two balls can be blocked in the groove; in addition, the steel wire surface usually has many oil stains and scales, and the oil stains and scales can enter between the two separation wheels after a long time of work, which not only accelerates the friction between the balls and the grooves, causes the balls to fail, but also causes the balls to be stuck due to too much impurities; all of these can cause the separation wheels to rotate synchronously and scratch the steel wires; and the fixed shaft is relatively fixed, when the separation wheels are stuck, the steel wires are rubbed and scratched. SUMMARY

[0007] In order to solve the above technical problems, the purpose of the present application is to provide a feeding separation roller for steel wire processing, by connecting the first separation wheel with the retainer ring, and rotating the second separation wheel on the retainer ring, so that the first separation wheel and the second separation wheel can rotate synchronously and relatively when the travel speeds of the steel wires are different, to avoid the abrasion of the steel wires; at the same time, the rotating shaft of the guide wheel set can also rotate between the bearing seats, so that even if the guide wheel set is stuck, the feeding of the steel wires can drive the rotating shaft and the guide wheel set to rotate, further avoiding the friction of the steel wires.

[0008] In order to achieve the above purpose, the present application adopts the following technical solutions:

[0009] The utility model provides a kind of feed separation roller for steel wire processing, including two bearing seats and rotating shaft connected on two bearing seats, the circumferential surface of rotating shaft is also rotatingly connected with multiple guide wheel groups for guiding steel wire in its axial direction, the guide wheel group includes the first separating wheel and the second separating wheel that can rotate around rotating shaft respectively, the circumferential surface of the first separating wheel has the first separating groove for accommodating the travel of steel wire, the circumferential surface of the second separating wheel has the second separating groove for accommodating the travel of steel wire;Second separating wheel and rotating shaft in the same guide wheel group are provided with retainer, and main bearing is provided between the retainer and the second separating wheel, so that the second separating wheel can rotate independently around main bearing, and the main bearing includes main bearing outer ring and main bearing inner ring, and relative rotation can occur between the first separating wheel and the second separating wheel;Second separating wheel and main bearing outer ring are interference fit, and both keep relative fixation in the axial direction of rotating shaft, and the retainer and the first separating wheel abut on both sides of main bearing inner ring respectively, so that the first separating wheel and the second separating wheel keep preset interval;In working state, each steel wire with different travel speed travels through the first separating groove and the second separating groove respectively, and can drive the first separating wheel and the second separating wheel to rotate respectively at the travel speed of steel wire matched with each other;Rotating shaft can drive guide wheel group to rotate together when guide wheel group and rotating shaft are jammed, to avoid hindering the travel of steel wire.

[0010] The arrangement of main bearing and retainer can make the first separating wheel and the second separating wheel relatively rotate when steel wire drives the rotation of the first separating wheel and the second separating wheel during travel, if two steel wires with different travel speeds fall into the first separating groove and the second separating groove respectively, one of the steel wires can drive the first separating wheel and the retainer to rotate together, but due to the effect of main bearing, the retainer can only drive main bearing inner ring to rotate at this time, and cannot affect main bearing outer ring, while the second separating wheel drives main bearing outer ring to rotate together when the other steel wire drives the second separating wheel to rotate, and the first separating wheel and the second separating wheel do not interfere with each other. And the presence of main bearing makes the first separating wheel and the second separating wheel keep preset interval, so as to avoid friction between them and cause wear, and also keep stable operation state of the two.

[0011] As preferred, the guide wheel group further includes first bearing and second bearing;First bearing is connected between the first separating wheel and the rotating shaft, and second bearing is connected between the inner ring wall of the retainer and the rotating shaft;First abutting part is formed on the inner ring wall of the first separating wheel in radial direction, and second abutting part is also formed on the inner ring wall of the retainer in radial direction, and the outer ring of first bearing and second bearing abuts first abutting part and second abutting part to make the first separating wheel and the retainer abut and rotate synchronously.

[0012] The first bearing and the second bearing enable the first separating wheel and the retainer ring to rotate relative to each other, and if a fixed connection is used, when the steel wires with different running speeds pass through the first separating wheel, the first separating wheels in different guide wheel groups will be affected, thereby causing the steel wires to be scratched. The first pressing part and the second pressing part are arranged to enable the first bearing and the second bearing to abut the first separating wheel and the retainer ring together, so that the first separating wheel and the retainer ring can rotate synchronously. The retainer ring provides a connection point of the main bearing, so that the second separating wheel does not interfere with the first separating wheel while cooperating with the main bearing.

[0013] Preferably, a first spacer ring is arranged between the first bearing and the second bearing in the same guide wheel group and is sleeved on the rotating shaft; and a second spacer ring is sleeved between the guide wheel groups and cooperates with the first spacer ring to fix the first bearing and the second bearing in the axial direction, and the second spacer ring forms a spacing between the guide wheel groups to avoid synchronous rotation of the guide wheel groups.

[0014] The first spacer ring and the second spacer ring enable the inner rings of the first bearing and the second bearing to abut each other, thereby making the overall structure more stable, and the second spacer ring also enables the guide wheel groups to have a certain spacing, so that adjacent guide wheel groups do not interfere with each other.

[0015] Preferably, the width of the first spacer ring is the same as the sum of the widths of the first pressing part and the second pressing part, so that the first bearing and the second bearing abut and limit each other through the first spacer ring while being able to respectively clamp the first pressing part and the second pressing part 401.

[0016] The first spacer ring is arranged to enable the first bearing and the second bearing to be more stable and the force to be more uniform when abutting against the first pressing part and the second pressing part.

[0017] Preferably, the retainer ring and the first separating wheel abut the inner ring of the main bearing on both sides, which means that the first separating wheel has a first recess formed on the end face, a retaining wall is formed beside the first recess, the retainer ring has a second recess formed on the circumferential side wall, and an annular convex retaining wall is formed beside the second recess; the main bearing is arranged in the first recess and the second recess, and the retaining wall and the annular convex retaining wall abut the inner ring of the main bearing on both sides.

[0018] The retaining wall and the annular convex retaining wall tightly clamp the inner ring of the main bearing, thereby making the main bearing more stable after installation, so that the connection point provided by the outer ring of the main bearing is more reliable, and the second separating wheel is more stable when cooperating with the main bearing.

[0019] Preferably, the inner ring wall of the second separating wheel is inwardly recessed to form a third recess, and the third recess is provided with an abutting portion on the side thereof, and the second separating wheel is provided with a clamping groove at a position corresponding to the third recess; and the main bearing outer ring is arranged in the third recess, and an elastic clamping ring is arranged in the clamping groove, and the abutting portion and the elastic clamping ring abut against the two sides of the main bearing outer ring respectively.

[0020] Similarly, the abutting portion and the elastic clamping ring are arranged to enable the second separating wheel to be closely matched with the main bearing outer ring, and to ensure stability during operation.

[0021] Preferably, the inner ring wall of the second separating wheel is inwardly recessed to form a third recess, and the third recess is provided with an abutting portion on the side thereof, and the second separating wheel is provided with a clamping groove at a position corresponding to the third recess; and the main bearing outer ring is arranged in the third recess, and an elastic clamping ring is arranged in the clamping groove, and the abutting portion and the elastic clamping ring abut against the two sides of the main bearing outer ring respectively.

[0022] The extension part can increase the contact area of the main bearing outer ring and the third recess, thereby improving the stability of the matching of the second separating wheel and the main bearing.

[0023] Preferably, the first separating wheel and the second separating wheel in the same guide wheel set are bent to form a gap through the avoidance of the extension part by the avoidance interval, so as to avoid the accumulation of external impurities at the preset interval position. Meanwhile, the gap also has the effect of delaying the entry of external impurities into the position of the main bearing.

[0024] Preferably, the outer diameters of the first separating wheel and the second separating wheel are different, and the outer diameter of the first separating wheel is smaller than that of the second separating wheel, so that a slope is formed at the opening of the first separating groove and the second separating groove to guide the steel wire to fall into the grooves.

[0025] The slope formed by the different outer diameters of the first separating wheel and the second separating wheel can prevent the steel wire from staying above the preset interval or above the adjacent guide wheel set during the movement of the steel wire, so that the steel wire can automatically fall into the first separating groove or the second separating groove.

[0026] Preferably, the shaft is further provided with a bearing wheel which rotates together with the shaft, and the circumferential surface of the bearing wheel is provided with a bearing groove for bearing the steel wire.

[0027] The arrangement of the bearing wheel enables the steel wire to continue to move even if it falls from the guide wheel set, without being stuck on the bearing seat and affecting the production.

[0028] Compared with the prior art, the present application has the following advantages:

[0029] 1、the first separating wheel and the second separating wheel in the guide wheel set can rotate according to the different running speeds of the steel wire, the steel wire can drive the first separating wheel and the abutting stop ring to rotate together, and the existence of the main bearing can make the second separating wheel rotate relative to the first separating wheel, and the two do not interfere with each other, compared with the setting of the ball, there is no large wear and it is more stable, and it is not easy to be affected by external impurities;

[0030] 2、the rotation of the rotating shaft between the two bearing seats also makes the rotating shaft rotate between the bearing seats even when the guide wheel set is stuck between the rotating shaft, that is, the guide wheel set and the rotating shaft rotate synchronously under the driving of the steel wire, and it will not affect the continuous work of other guide wheel sets, while the traditional fixed shaft is relatively stationary, when the separating wheel is stuck, the separating wheel and the fixed shaft are also stationary, at this time, the steel wire will be scratched when passing through the separating groove, and the relative rotation of the rotating shaft can further avoid scratching the steel wire;

[0031] 3、the extension and the avoidance interval can delay and prevent the entry of external impurities, and avoid causing the jamming of the separating wheel;

[0032] 4、the traditional separating wheel has the same size, so the height of the notch is relatively flat, and the gap between the separating wheels makes the steel wire unable to fall into the separating groove, and the acting force generated when the steel wire runs will also increase the gap; the different outer diameters of the first separating wheel and the second separating wheel make the first separating groove and the second separating groove have a height difference and form a slope at the notch position, and the steel wire will automatically fall into the corresponding separating groove when passing through the position.

[0039] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0040] In this embodiment, a feed separation roller for steel wire processing is specifically disclosed, such as... Figures 1-5 As shown, its specific structure includes two bearing seats 1 and a rotating shaft 2 rotatably connected to the two bearing seats 1. Multiple guide wheel groups 3, arranged sequentially for guiding steel wires, are rotatably connected to the circumferential surface of the rotating shaft 2 along its axial direction. Each guide wheel group 3 includes a first separating wheel 301 and a second separating wheel 302, which can rotate around the rotating shaft 2 respectively. The circumferential surface of the first separating wheel 301 has a first separating groove 3011 for accommodating the movement of the steel wire, and the circumferential surface of the second separating wheel 302 has a second separating groove 3021 for accommodating the movement of the steel wire. A retaining ring 4 is provided between the second separating wheel 302 in the same guide wheel group 3 and the rotating shaft 2. A main bearing 9 is provided between the retaining ring 4 and the second separating wheel 302, so that the second separating wheel 302 can rotate independently around the main bearing 9. The main bearing 9 includes a main bearing outer ring. The inner ring 901 and the main bearing inner ring 902, the first separating wheel 301 and the second separating wheel 302 can rotate relative to each other; the second separating wheel 302 is interference-fitted with the outer ring 901 of the main bearing and the two remain relatively fixed in the axial direction along the rotating shaft 2; the retaining ring 4 and the first separating wheel 301 respectively abut against both sides of the inner ring 902 of the main bearing, so that the first separating wheel 301 and the second separating wheel 302 maintain a preset interval 11; in the working state, when each steel wire with a different travel speed travels through the first separating groove 3011 and the second separating groove 3021 respectively, it can drive the first separating wheel 301 and the second separating wheel 302 to rotate in accordance with the travel speed of the steel wire; the rotating shaft 2 can drive the guide wheel group 3 to rotate together when the guide wheel group 3 is stuck with the rotating shaft 2 to avoid obstructing the travel of the steel wire.

[0041] In the installation of the feed separation roller in the embodiment, the first separation wheel 301 is first installed on the rotating shaft 2, then the main bearing 9 is assembled with the second separation wheel 302, and then the main bearing 9 is assembled with the retainer ring 4, which can also be assembled in advance. Finally, the first separation wheel 301 and the second separation wheel 302 are assembled to form a guide wheel set. The main bearing 9 and the retainer ring 4 are arranged so that when the steel wire drives the rotation of the first separation wheel 301 and the second separation wheel 302 during the running process, the first separation wheel 301 and the second separation wheel 302 can rotate relatively. If two steel wires with different running speeds fall into the first separation groove 3011 and the second separation groove 3021 respectively, one of the steel wires can drive the first separation wheel 301 and the retainer ring 4 to rotate together. Due to the action of the main bearing 9, the retainer ring 4 can only drive the inner ring 902 of the main bearing to rotate at this time, and cannot affect the outer ring 901 of the main bearing. The other steel wire drives the second separation wheel 302 to rotate, and the second separation wheel 302 drives the outer ring 901 of the main bearing to rotate. The first separation wheel 301 and the second separation wheel 302 do not interfere with each other. The presence of the main bearing 9 makes the first separation wheel 301 and the second separation wheel 302 maintain a predetermined interval 11, so as to avoid friction between the two and cause wear. It can also maintain the stable running state of the two.

[0042] The guide wheel set 3 further comprises a first bearing 5 and a second bearing 6. The first bearing 5 is connected between the first separation wheel 301 and the rotating shaft 2, and the second bearing 6 is connected between the inner ring wall of the retainer ring 4 and the rotating shaft 2. The first separation wheel 301 has a first pressing portion 3012 formed on the inner ring wall in the radial direction. The retainer ring 4 also has a second pressing portion 401 formed on the inner ring wall in the radial direction. The outer rings of the first bearing 5 and the second bearing 6 press the first pressing portion 3012 and the second pressing portion 401 to make the first separation wheel 301 and the retainer ring 4 abut and rotate synchronously.

[0043] When the first separating wheel 301 and the second separating wheel 302 are installed, the first separating wheel 301 and the retainer ring 4 are rotatably connected to the rotating shaft 2 through the first bearing 5 and the second bearing 6, and the first separating wheel 301 and the retainer ring 4 can relatively rotate between the first bearing 5 and the second bearing 6. If the first separating wheel 301 and the retainer ring 4 are fixedly connected, when the steel wires with different running speeds pass through the first separating wheel 301, the first separating wheel 301 in different guide wheel groups will be affected, and the steel wires will be scratched. The first pressing part 3012 and the second pressing part 401 can make the first separating wheel 301 and the retainer ring 4 abut against each other through the first bearing 5 and the second bearing 6, so that the first separating wheel 301 and the retainer ring 4 can synchronously rotate. If the retainer ring 4 is not provided, and the second separating wheel 302 is directly connected to the second bearing 6, the structure is simpler, but the running steel wires have a large force, and under long-time production, the first separating wheel 301 and the second separating wheel 302 will be offset to one side in the axial direction, the gap between the first separating wheel 301 and the second separating wheel 302 will become larger and larger, the gap between the first bearing 5 and the second bearing 6 will also become larger and larger, and the first separating wheel 301 and the second separating wheel 302 will be in contact and friction under the action of the force. The retainer ring 4 provides a connection point of the main bearing 9, so that the second separating wheel 302 cooperates with the main bearing 9 without interfering with the first separating wheel 301. Through cooperation of the first pressing part 3012 and the second pressing part 401, the structure is more stable.

[0044] In addition, the first separating wheel 301 and the second separating wheel 302 are rotatably connected to the rotating shaft 2 through the first bearing 5 and the second bearing 6, and the first separating wheel 301 and the retainer ring 4 can relatively rotate between the first bearing 5 and the second bearing 6. If the first separating wheel 301 and the retainer ring 4 are fixedly connected, when the steel wires with different running speeds pass through the first separating wheel 301, the first separating wheel 301 in different guide wheel groups will be affected, and the steel wires will be scratched. The first pressing part 3012 and the second pressing part 401 can make the first separating wheel 301 and the retainer ring 4 abut against each other through the first bearing 5 and the second bearing 6, so that the first separating wheel 301 and the retainer ring 4 can synchronously rotate. If the retainer ring 4 is not provided, and the second separating wheel 302 is directly connected to the second bearing 6, the structure is simpler, but the running steel wires have a large force, and under long-time production, the first separating wheel 301 and the second separating wheel 302 will be offset to one side in the axial direction, the gap between the first separating wheel 301 and the second separating wheel 302 will become larger and larger, the gap between the first bearing 5 and the second bearing 6 will also become larger and larger, and the first separating wheel 301 and the second separating wheel 302 will be in contact and friction under the action of the force. The retainer ring 4 provides a connection point of the main bearing 9, so that the second separating wheel 302 cooperates with the main bearing 9 without interfering with the first separating wheel 301. Through cooperation of the first pressing part 3012 and the second pressing part 401, the structure is more stable.

[0045] The first separating wheel 301 and the second separating wheel 302 are rotatably connected to the rotating shaft 2 through the first bearing 5 and the second bearing 6, and the first separating wheel 301 and the retainer ring 4 can relatively rotate between the first bearing 5 and the second bearing 6. If the first separating wheel 301 and the retainer ring 4 are fixedly connected, when the steel wires with different running speeds pass through the first separating wheel 301, the first separating wheel 301 in different guide wheel groups will be affected, and the steel wires will be scratched. The first pressing part 3012 and the second pressing part 401 can make the first separating wheel 301 and the retainer ring 4 abut against each other through the first bearing 5 and the second bearing 6, so that the first separating wheel 301 and the retainer ring 4 can synchronously rotate. If the retainer ring 4 is not provided, and the second separating wheel 302 is directly connected to the second bearing 6, the structure is simpler, but the running steel wires have a large force, and under long-time production, the first separating wheel 301 and the second separating wheel 302 will be offset to one side in the axial direction, the gap between the first separating wheel 301 and the second separating wheel 302 will become larger and larger, the gap between the first bearing 5 and the second bearing 6 will also become larger and larger, and the first separating wheel 301 and the second separating wheel 302 will be in contact and friction under the action of the force. The retainer ring 4 provides a connection point of the main bearing 9, so that the second separating wheel 302 cooperates with the main bearing 9 without interfering with the first separating wheel 301. Through cooperation of the first pressing part 3012 and the second pressing part 401, the structure is more stable.

[0046] The first separating wheel 301 and the second separating wheel 302 are rotatably connected to the rotating shaft 2 through the first bearing 5 and the second bearing 6, and the first separating wheel 301 and the retainer ring 4 can relatively rotate between the first bearing 5 and the second bearing 6. If the first separating wheel 301 and the retainer ring 4 are fixedly connected, when the steel wires with different running speeds pass through the first separating wheel 301, the first separating wheel 301 in different guide wheel groups will be affected, and the steel wires will be scratched. The first pressing part 3012 and the second pressing part 401 can make the first separating wheel 301 and the retainer ring 4 abut against each other through the first bearing 5 and the second bearing 6, so that the first separating wheel 301 and the retainer ring 4 can synchronously rotate. If the retainer ring 4 is not provided, and the second separating wheel 302 is directly connected to the second bearing 6, the structure is simpler, but the running steel wires have a large force, and under long-time production, the first separating wheel 301 and the second separating wheel 302 will be offset to one side in the axial direction, the gap between the first separating wheel 301 and the second separating wheel 302 will become larger and larger, the gap between the first bearing 5 and the second bearing 6 will also become larger and larger, and the first separating wheel 301 and the second separating wheel 302 will be in contact and friction under the action of the force. The retainer ring 4 provides a connection point of the main bearing 9, so that the second separating wheel 302 cooperates with the main bearing 9 without interfering with the first separating wheel 301. Through cooperation of the first pressing part 3012 and the second pressing part 401, the structure is more stable.

[0047] The first spacer ring 7 is arranged to make the first bearing 5 and the second bearing 6 more stable and the force more uniform when abutting against the first pressing part 3012 and the second pressing part 401. Without the first spacer ring 7, the outer ring of the first bearing 5 and the second bearing 6 abuts against the first pressing part 3012 and the second pressing part 401, but the inner ring of the first bearing 5 and the second bearing 6 is empty. At this time, the force of the first bearing 5 and the second bearing 6 is not uniform, which will affect the first separating wheel 301 and the second separating wheel 302.

[0048] The first separating wheel 301 is formed with a first recessed platform 303 on the end face, and a blocking wall 307 is formed beside the first recessed platform 303. The retainer ring 4 is formed with a second recessed platform 402 on the circumferential side wall, and an annular convex blocking part 403 is formed beside the second recessed platform 402. The main bearing 9 is arranged in the first recessed platform 303 and the second recessed platform 402, and the blocking wall 307 and the annular convex blocking part 403 abut on both sides of the inner ring 902 of the main bearing, respectively.

[0049] The blocking wall 307 and the annular convex blocking part 403 can tightly clamp the inner ring 902 of the main bearing, so that the main bearing 9 is more stable after installation, and the connection point provided by the outer ring 901 of the main bearing is more reliable, and the second separating wheel 302 is more stable when cooperating with the main bearing.

[0050] On the other hand, the third recessed platform 304 is formed on the inner ring wall of the second separating wheel 302, and an abutting part 3023 is formed beside the third recessed platform 304. The second separating wheel 302 is provided with a clamping groove 305 at the position corresponding to the third recessed platform 304. The outer ring 901 of the main bearing is arranged in the third recessed platform 304, and the elastic ring 306 is arranged in the clamping groove 305. The abutting part 3023 and the elastic ring 306 abut on both sides of the outer ring 901 of the main bearing, respectively.

[0051] Similarly, the abutting part 3023 and the elastic ring 306 are arranged to make the second separating wheel 302 tightly cooperate with the outer ring 901 of the main bearing, and ensure the stability during work. In this way, the outer ring 901 of the main bearing and the inner ring 902 of the main bearing can be effectively clamped and fixed, so that the structure is more compact and stable.

[0052] In addition, the inner ring wall of the second separating wheel 302 extends in the axial direction to the direction of the first separating wheel 301 in the same guide wheel set 3 to form an extension part 3022. The extension part 3022 cooperates with the main body of the second separating wheel 302 to contain and cooperate with the main bearing 9 in the width direction. The first separating wheel 301 is also formed with an avoidance interval 3013 at the middle position for accommodating the extension part 3022, and the avoidance interval 3013 penetrates the pre-set interval 11.

[0053] The extension 3022 can increase the contact area between the main bearing outer ring 901 and the third recess 304, thereby improving the stability of the second separating wheel 302 and the main bearing 9.

[0054] Meanwhile, the extension 3022 is formed with a bent gap between the first separating wheel 301 and the second separating wheel 302 in the same guide wheel set 3 through the avoidance interval 3013, so as to avoid the accumulation of external impurities at the preset interval 11 position. Meanwhile, the gap also has the effect of delaying the entry of external impurities into the position of the main bearing 9.

[0055] On the other hand, the outer diameters of the first separating wheel 301 and the second separating wheel 302 are different, and the outer diameter of the first separating wheel 301 is smaller than that of the second separating wheel 302, so that a slope is formed at the opening of the first separating groove 3011 and the second separating groove 3021, and the steel wire falls into the groove automatically.

[0056] The slope formed by the different outer diameters of the first separating wheel 301 and the second separating wheel 302 can make the steel wire not stay above the preset interval 11 during the running process, nor stay above the adjacent guide wheel set, so that the steel wire can automatically slide into the first separating groove 3011 or the second separating groove 3021. If the outer diameters of the first separating wheel 301 and the second separating wheel 302 are the same, the opportunity of the steel wire staying above the preset interval 11 between the first separating wheel 301 and the second separating wheel 302 will increase, and if the steel wire stays there for a long time, not only will the steel wire be scratched, but also the preset interval 11 between the first separating wheel 301 and the second separating wheel 302 will become larger, thereby blocking the running of the steel wire. Or if the outer diameters of the first separating wheel 301 and the second separating wheel 302 are the same, the steel wire will also be stuck between the adjacent guide wheel sets, which will also affect the running of the steel wire.

[0057] The shaft 2 is further sleeved with a bearing wheel 10 that rotates with the shaft 2 beside the bearing seat 1, and the circumferential surface of the bearing wheel 10 has a bearing groove 1001 for bearing the steel wire.

[0058] The setting of the bearing wheel 10 makes the steel wire continue to run on the bearing wheel 10 even if it falls off the guide wheel set, without being stuck on the bearing seat 1, affecting production.

[0059] The above described in the specification is only an example of the present application. Those skilled in the art can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, as long as they do not deviate from the content of the specification or exceed the scope defined by the claims.
