Description

TECHNICAL FIELD

[0001] The present application relates to the field of steel processing, in particular to a wire outlet mechanism and a method thereof. BACKGROUND

[0002] Steel wire rust refers to the surface oxidation phenomenon caused by moisture oxidation, harmful gas impregnation and other factors during storage of steel wire. If the steel wire rust is not cleaned in time, it will continue to corrode the inner layer of the steel wire. At present, the main methods for removing rust from steel wire include sand blasting, pickling and polishing. The sand blasting method has high dependence on manual work and produces a large amount of dust during construction, which is harmful to the surrounding environment and the workers. The pickling method uses acid in the pickling solution to react with metal oxides to dissolve the metal oxides and remove the rust and dirt on the surface of the steel. However, a large amount of water is needed to clean the steel after pickling, which will generate a large amount of waste water and waste acid, causing environmental pollution. At present, polishing has gradually become the mainstream method for treating steel wire rust.

[0003] The existing polishing device polishes multiple steel wires arranged side by side at the same time to ensure polishing efficiency. The invention patent with the Chinese patent publication number CN110745624 and the publication date of 2020.02.04 discloses a discharging machine for a steel wire rust removal production line, which includes a steel wire separation assembly, a tensioning traction mechanism and a cross-shaped wheel group mechanism. The steel wire passes through the cross-shaped wheel group mechanism, the tensioning traction mechanism and the steel wire separation assembly in sequence and enters the subsequent polishing device. The first inclined guide wheels of the tensioning traction mechanism send the steel wire into the steel wire separation assembly. In this application, multiple first inclined guide wheels are arranged at intervals on the mounting frame. The first inclined guide wheels are detachably connected to the mounting frame by bolts and nuts. When guiding the steel wire, the first inclined guide wheels need to withstand a large radial pressure. After long-term work, the nuts are prone to loosen, which will cause the first inclined guide wheels to twist and affect the guiding effect of the steel wire. In addition, the first inclined guide wheels are fixed to the mounting frame by the bracket. Precise positioning of the first inclined guide wheels is required during installation, which is difficult to install. SUMMARY

[0036] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0038] The specific embodiments of the present invention are as follows:

[0039] Example 1: As Figures 1-11 As shown, the present invention provides a wire feeding mechanism and its usage method, including a wire drawing wheel 1, a wire drawing groove 2 on the outer circumferential surface of the wire drawing wheel 1, and a wire feeding mechanism 29 including a fixed base 3 and a mounting rod 4 slidably disposed on the fixed base 3 in the front-back direction. The mounting rod 4 is vertically disposed downwards, and the wire drawing wheel 1 is rotatably disposed on the mounting rod 4. The fixed base 3 is provided with a locking assembly, and the mounting rod 4 is provided with a through hole 5 along the axial direction. The axis of the through hole 5 is collinear with the axis of the mounting rod 4. The locking assembly includes a bolt 6 and a locking block 7. The bolt 6 includes a screw 8 and a screw head 9. The locking block 7 is provided with a threaded hole adapted to the screw 8. The fixed base 3 is provided with a strip hole 11, which is disposed in the front-back direction. The width of the strip hole 11 is greater than the diameter of the screw 8. The screw 8 passes through the through hole 5 and the strip hole 11 in sequence and is connected to the locking block 7 through the threaded hole. At this time, the screw head 9 abuts against the mounting rod 4.

[0040] In the present scheme, the wire guide mechanism 29 is used to guide the wire to turn, wherein the position of the wire guide wheel 1 determines the wire turning position, the wire guide wheel 1 is fixed on the fixed seat 3 through the mounting rod 4, and the position of the wire guide wheel 1 is adjusted by changing the position of the mounting rod 4. The locking assembly has a locked state and an unlocked state. When the locking assembly is in the locked state, the bolt 6 presses the mounting rod 4 tightly on the fixed seat 3, at this time the top surface of the mounting rod 4 is tightly attached to the bottom surface of the fixed seat 3, and the mounting rod 4 is fixed on the fixed seat 3; when the locking assembly is in the unlocked state, the top surface of the mounting rod 4 is no longer tightly attached to the bottom surface of the fixed seat 3, at this time the locking block 7 can be pushed to make the mounting rod 4 slide along the strip-shaped hole 11 to the desired position. In work, the wire turns along the wire guide groove 2 of the wire guide wheel 1, when it is necessary to change the turning position of the wire, the staff first adjusts the locking assembly to the unlocked state, then moves the mounting rod 4 to the desired position, and then adjusts the locking assembly to the locked state, and fixes the mounting rod 4 at the desired position. In the locked state, the screw head 9 abuts against the mounting rod 4, the screw rod 8 is connected with the locking block 7, and the mounting rod 4 is pressed tightly between the screw head 9 and the fixed seat 3, at this time the position of the mounting rod 4 cannot be moved, in the unlocked state, the screw rod 8 of the bolt 6 does not need to be separated from the locking block 7, in the present embodiment, the strip-shaped hole 11 is a waist-shaped hole, the two ends of the waist-shaped hole have a curvature, which is convenient for cooperation with the screw rod 8. It can be understood that the function of the bolt 6 is only to press the mounting rod 4 tightly on the fixed seat 3, the screw rod 8 moves downward, the mounting rod 4 is no longer pressed tightly and can be moved, and the screw head 9 and the mounting rod 4 are further provided with a gasket 30, which ensures that the screw rod 8 will not be loose after being connected with the locking block 7. In addition, when switching between the unlocked state and the locked state, the locking block 7 needs to be fixed to prevent the bolt 6 from rotating the locking block 7. It should be noted that the locking block 7 is a metal block with a certain weight, and its mass is much greater than the nut mentioned in the background art, which increases the friction between the locking block 7 and the fixed seat 3, and ensures the stability of the connection between the locking block 7 and the fixed seat 3.

[0041] As Figures 3 to 5As shown, the bottom surface of the fixing base 3 is provided with a sliding groove 12 in the front-rear direction, and the left and right side walls of the sliding groove 12 are symmetrically provided with two support blocks 13. The outer circumferential surface of the mounting rod 4 is provided with a flange 14, the flange 14 is slidingly arranged in the sliding groove 12 and the bottom surface abuts against the top surface of the support block 13. The diameter of the part of the mounting rod 4 below the flange 14 is smaller than the distance between the two support blocks 13. In this embodiment, the thickness of the flange 14 is smaller than the distance between the top surface of the sliding groove 12 and the top surface of the support block 13, and the diameter of the corresponding position of the mounting rod 4 and the support block 13 is smaller than the distance between the side walls of the two support blocks 13, so that the flange 14 is hung on the support block 13 of the side wall of the sliding groove 12 and can slide in the sliding groove 12, facilitating the assembly of the mounting rod 4 and the fixing base 3. In addition, when the worker adjusts the bolt 6 to disengage the mounting rod 4, the mounting rod 4 will not disengage the fixing base 3, reducing the risk of damaging the wire guiding wheel 1. It should be noted that the shape of the flange 14 is not limited, and the flange 14 in this embodiment adopts a ring-shaped flange. The top surface of the ring-shaped flange is located at the same horizontal plane as the top surface of the mounting rod 4, and an avoiding groove 26 is arranged below the ring-shaped flange. By arranging the avoiding groove 26, the diameter of the corresponding position of the mounting rod 4 and the support block 13 is smaller than the distance between the side walls of the two support blocks 13. By arranging the top surface of the ring-shaped flange at the same horizontal plane as the top surface of the mounting rod 4, the contact area between the top surface of the mounting rod 4 and the top surface of the sliding groove is increased, and the locking assembly is more stable when it is in the locked state. It can be understood that the shape of the flange 14 is not limited, and it can also be a square flange 14. In actual production, the appropriate shape of the flange 14 can be selected according to different needs. By arranging the sliding groove 12, the support block 13 and the flange 14 on the mounting rod 4, the sliding connection between the mounting rod 4 and the fixing base 3 is realized, and the difficulty of adjusting the position of the wire guiding wheel 1 is reduced.

[0042] As shown in Figure 3 , the top surface of the fixing base 3 is provided with a groove 15, and the groove 15 is arranged in the front-rear direction of the fixing base 3. The locking block 7 is slidingly arranged in the groove 15. The width of the groove 15 is similar to the width of the locking block 7. When switching between the unlocked state and the locked state, the bolt 6 needs to be loosened and tightened. Since the locking block 7 is limited in the groove 15 and will not rotate with the bolt 6, the difficulty of adjusting the position of the wire guiding wheel 1 is reduced. In this embodiment, the top surface of the locking block 7 is flush with the top surface of the groove 15, which ensures the integrity of the locking block 7 and the fixing base 3.

[0043] As shown in Figure 1 and Figure 2As shown, the locking block 7 is provided with a handle 16. In actual operation, the staff pushes the handle 16 to slide the locking block 7 in the groove 15. In the embodiment, the groove 15 is communicated with the front end surface of the fixing seat 3, and the handle 16 is connected with the front end surface of the locking block 7. Specifically, the handle 16 includes a rod part and a holding part. The rod part of the handle 16 is connected with the front end surface of the locking block 7. When it is needed to adjust the position of the yarn guide wheel 1, the locking block 7 is pulled along the length direction of the groove 15 through the holding part of the handle 16. By arranging the handle 16, the staff can move the locking block 7 conveniently. It should be noted that the handle 16 can also be installed on the top surface of the locking block 7. The installation position of the handle 16 is not limited. The function of the handle 16 is only to facilitate the movement of the locking block 7.

[0044] As shown in the drawings, Figure 2 As shown, the mounting rod 4 is sleeved with a bearing 17, and the yarn guide wheel 1 is sleeved on the bearing 17. The bearing 17 includes an inner ring, rolling elements and an outer ring. The inner ring is in interference fit with the mounting rod 4, and the outer ring is in interference fit with the yarn guide wheel 1. By arranging the bearing 17, the rotation of the yarn guide wheel 1 is stable, and the bearing capacity is good. In the embodiment, the mounting rod 4 is provided with a bearing installation step 23 and a retainer groove 24. The retainer groove 24 is provided with a bearing retainer 25. The bearing 17 is limited between the bearing installation step 23 and the bearing retainer 25.

[0045] A method for using the yarn feeding mechanism includes the following steps: a plurality of yarn feeding mechanisms are respectively installed on two installation racks 18 arranged side by side. The two installation racks 18 are arranged at intervals to form a feeding channel 20. The plurality of yarn feeding mechanisms are arranged at intervals along the length direction of the installation rack 18. The heights of all the yarn guide wheels 1 are consistent. The yarn guide wheels 1 are connected with the installation rack 18 through the fixing seat. At this time, the yarn guide wheels 1 of the yarn feeding mechanism are at least partially located in the feeding channel 20. After installation, the inner side edge of the installation rack 18 is taken as a reference to adjust the position of the mounting rod, so that the centers of the plurality of yarn guide wheels 1 are arranged in a stepped manner which gradually shrinks inward along the length direction of the installation rack 18.

[0046] A plurality of yarn feeding mechanisms are respectively installed on two installation racks 18 arranged side by side. The two installation racks 18 are arranged at intervals to form a feeding channel 20. A steel wire guide roller 21 is arranged horizontally at the front end of the feeding channel 20. A plurality of steel wire walking roller tracks 22 are arranged on the steel wire guide roller 21 in the axial direction. The two adjacent steel wire walking roller tracks 22 are kept at a fixed distance.

[0047] A plurality of yarn delivery mechanisms 29 are arranged along the length direction of the mounting frame 18, and the heights of all the yarn guide wheels 1 are consistent. The yarn guide wheels 1 are connected to the mounting frame 18 through the fixing seat 3, and at this time, the yarn guide wheels 1 of the yarn delivery mechanism 29 are at least partially located in the feeding channel 29. After the initial installation of the yarn guide wheels 1 is completed, the position adjustment is performed. Taking the inner side edge of the mounting frame 18 as the reference, the position of the mounting rod 4 is adjusted, and the centers of the plurality of yarn guide wheels 1 are arranged in a stepped manner gradually inward along the width direction of the mounting frame 18 from back to front. On each row of the mounting frame 18, the distance between the centers of the adjacent two yarn guide wheels 1 in the width direction is equal to the fixed distance between the two adjacent steel wire walking roller ways 22.

[0048] A plurality of steel wire coils 31 are symmetrically arranged on the outer sides of the two mounting frames 18 respectively, and each steel wire coil 31 corresponds to the yarn delivery mechanism 29. The movable end of the steel wire on the steel wire coil 31 is introduced into the feeding channel through the lead groove 2 of the corresponding yarn guide wheel 1. Finally, each steel wire respectively enters the steel wire walking roller way 22 of the steel wire guide roller 21 along the direction perpendicular to the center axis of the steel wire guide roller 21.

[0049] In the present scheme, the movable end of the steel wire on the steel wire coil 31 is transmitted into the feeding channel 20 through the corresponding yarn guide wheel 1. Specifically, the steel wire enters the feeding channel 20 along the partial arc segment of the lead groove 2 of the yarn guide wheel 1, and at this time, the transmission direction of the steel wire coincides with the tangent of the lead groove 2 of the yarn guide wheel 1, so that all the steel wires in the feeding channel 20 are parallel to each other. Since the heights of the yarn guide wheels 1 are consistent, all the steel wires are coplanar in the feeding channel 20, and the difference between the two yarn guide wheels 1 extending into the feeding channel 20 is consistent with the distance between the two adjacent steel wires in the feeding channel 20. In addition, all the steel wires remain parallel and can enter the steel wire walking roller way 22 along the direction perpendicular to the axis of the steel wire guide roller 21, avoiding the axial pressure of the steel wire on the steel wire walking roller way 22.

[0050] The step of adjusting the position of the mounting rod by the handle includes:

[0051] The screw rod 8 is lowered by rotating the screw head 9 until the top surface of the screw rod 8 is no longer tightly fitted with the top surface of the sliding groove 12, and then the locking block is moved by the handle 16, and the mounting rod 4 is moved along the strip-shaped hole 11 under the driving of the locking block 7.

[0052] Taking the inner side edge of the mounting frame 18 as the reference, when the mounting rod 4 is moved to the required position, the screw rod 8 is raised by rotating the screw head 9 until the top surface of the screw rod 8 is tightly fitted with the top surface of the sliding groove 12, and the adjustment of the position of the mounting rod 4 is completed. It can be understood that the position of the mounting rod 4 is adjusted to change the position of the yarn guide wheel 1, and the position of the mounting rod 4 is adjusted to provide a fault tolerance space for the installation of the fixing seat 3 on the mounting frame. In actual work, if the installation of the fixing seat 3 deviates, the position of the yarn guide wheel 1 is corrected by adjusting the mounting rod 4.

[0053] Example 2: as shown in Figure 12 The difference between this embodiment and example 1 is that the diameter of the lower part of the ring-shaped flange where the mounting rod 4 is located is smaller than the distance between the two support blocks 13.

[0054] The above description of the application and its embodiments is illustrative and not restrictive, and the actual structure is not limited to the one shown in the drawings. Therefore, if a person skilled in the art is inspired by it, without departing from the purpose of the application, similar structural forms and embodiments can be designed without creativity, and they should all belong to the protection scope of the application.
