Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of wire and cable manufacturing, and particularly relates to a guiding mechanism for flat cable flat winding and a use method thereof. BACKGROUND

[0002] Most wire and cable products are of circular cross section, but there are also many flat cross section wire and cables. The processing and manufacturing of flat cable are not significantly different from those of circular cross section wire and cable, but since the cross section of flat cable is nearly rectangular, the movement of the cable is distinguished by direction during the manufacturing process, especially during winding and winding. If the cable movement is shaken and the direction is deflected, it will directly lead to uneven winding and affect the appearance of the product. Even the cables of adjacent layers cross, causing the cables to be squeezed and scraped between layers, resulting in damage to the cable surface and deformation of the appearance, forming defective products or even unqualified products. Therefore, the winding and winding of flat cable require different guiding mechanisms for the cable. At the same time, due to the difference between the cross section of flat cable and circular cable, the winding and winding of flat cable is divided into vertical winding and horizontal winding, and the guiding mechanisms used for different types of winding and winding are also different.

[0003] In the process of implementing the present application, the inventors found that the prior art at least has the following problems:

[0004] At present, most cable guiding mechanisms in front of winding and winding can be used for producing circular cables and flat cables, but when used for producing flat cross section cables, the quality of winding and winding will be affected. Because winding and winding mainly involves rotating the cable reel to take up the cable, and the winding mechanism reciprocates parallel to the axis of the cable reel, the movement of the winding mechanism will change the direction of the cable movement. Since the cross section of flat cable is nearly rectangular, the change of direction during cable movement will cause the cable to twist and the cross section of the cable to change direction. During winding and winding, if the cross section of the cable changes direction, it will directly lead to uneven winding and affect the appearance of the product. Since the movement of the winding mechanism is a necessary action process, therefore, in order to ensure the quality of flat cable winding and winding, it is necessary to accurately position and guide the flat cross section cable in motion, reduce the probability of the cross section of the cable changing direction caused by the twisting of the cable due to the movement of the winding mechanism. SUMMARY

DETAILED DESCRIPTION

[0032] ​Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0033] Referring to Figures 1-2 A flat cable 1 flat winding guiding mechanism, the guiding mechanism is composed of a first elastic cross-shaped guide roller set, a second elastic cross-shaped guide roller set and a flat groove wheel;

[0034] A cable reel 2, the cable 1 is wound on the cable reel 2;

[0035] A wire arranging mechanism 3, there are two wire arranging mechanisms 3, the cable 1 on the cable reel 2 passes through the two wire arranging mechanisms 3;

[0036] A first elastic cross-shaped guide roller set 4a and a second elastic cross-shaped guide roller set 4b, the two wire arranging mechanisms 3 are respectively provided with the first elastic cross-shaped guide roller set 4a and the second elastic cross-shaped guide roller set 4b; the cable 1 passes through the first elastic cross-shaped guide roller set 4a and the second elastic cross-shaped guide roller set 4b; the elastic cross-shaped guide roller set 4 is fixedly installed on the fixed support 6, the flat groove wheel 5 is movably connected with the fixed support 6, the flat groove wheel 5 can rotate around the center of the elastic cross-shaped guide roller set 4, and the rotation angle is set to 2.2β-2.6β, and is not greater than 60°.

[0037] The elastic cross-shaped guide roller set 4 is composed of two sets of elastic double guide roller sets which are horizontally installed or vertically installed; each set of elastic double guide roller set is composed of two guide rollers 41, a mandrel 42, two top rods 43, two compression springs 44, two adjusting screws 45 and a base 46.

[0038] A flat groove wheel 5, each of the two wire arranging mechanisms 3 is provided with a flat groove wheel 5, and the cable 1 passes through the flat groove wheel 5.

[0039] The first elastic cross-shaped guide roller set 4a and the second elastic cross-shaped guide roller set 4b have: a base 46 installed on the wire arranging mechanism 3; a pair of roller frames, a first end of the roller frame is hinged to the base 46; a guide roller 41 installed on the roller frame; the cable 1 passes through the guide rollers 41 of the pair of roller frames; and a damping mechanism, the first end of the roller frame is in contact with the base 46 through the damping mechanism.

[0040] The damping mechanism includes a compression spring 44 and a top rod 43, a first end of the compression spring 44 is installed in the base 46, a first end of the top rod 43 is in contact with a second end of the compression spring 44, and a second end of the top rod 43 is in contact with the first end of the roller frame. The rotating guide roller 41 is quickly reset to the normal state when the rotating thrust is lost by the compression spring 44, so that the two guide rollers 41 tightly clamp the cable 1.

[0041] The adjusting mechanism in the base 46 is an adjusting screw 45 which is screwed with the base 46, and the end of the adjusting screw 45 is in contact with the first end of the compression spring 44. The base 46 is provided with a hole for accommodating the top rod 43, the top rod 43 has one end for accommodating the compression spring 44, and the adjusting screw 45 is used to adjust the pressure of the compression spring 44.

[0042] The deflection angle of the cable 1 is β, the flat groove wheel 5 is movably installed on the fixed support 6, the flat groove wheel 5 can rotate around the center of the elastic cross-shaped guide roller group, and the rotation angle is set to 2.2β-2.6β, and is not greater than 60°.

[0043] The guide roller 41 is rotatably installed on the base 46 through the mandrel 42. The movable angle of the roller frame around the base 46 is β1, and β1 is β / 2. The mandrel 42 is detachably fixedly connected with the base 46, and the mandrel 42 is movably connected with the L-shaped shafts of the two guide rollers 41; the guide roller 41 can rotate around the mandrel, and the rotation angle is β1, and β1 is β / 2.

[0044] The maximum value of the β angle should not be greater than 25°, the β angle is determined by the center distance between the fixed support 6 and the cable arranging mechanism 3 and the width of the disc, and generally, the maximum disc width used for manufacturing the cable is ≯1200mm, so the center distance between the fixed support 6 and the cable arranging mechanism 3 should be not less than 1300mm, and generally, the existing equipment layout distance fully meets this requirement.

[0045] The base 46 is provided with symmetrical inclined concave tables, the roller frame end surface is in contact with the inclined concave tables, and the rotation angle of the roller frame is limited to β1.

[0046] The width of the wheel groove of the flat groove wheel 5 is 1.1-1.3 times the width of the flat cable 1, and the included angle of the two sides of the wheel groove is 1 times β.

[0047] The use method of the above-mentioned flat cable 1 flat winding guiding mechanism includes the following steps:

[0048] 1) the flat cable 1 after extrusion is in the state of wide surface downward, and is sequentially threaded through the elastic cross-shaped guide roller group 4a, the flat groove wheel 5, the elastic cross-shaped guide roller group 4b, the flat groove wheel 5b, and is fixed on the cable disc 2;

[0049] 2) the cable disc 2 rotates to start the flat winding of the flat cable 1, and the cable arranging mechanism 3 moves synchronously to drive the left and right movement of the cable 1 according to the set step distance;

[0050] 3) When the winding mechanism 3 moves from the left side to the right side of the cable reel 2, the angle β changes from the maximum value to 0 to the maximum value. The change of the angle β will certainly cause the twisting of the flat cable 1. The traditional guide mechanism cannot effectively hold the cable 1 when the cable is twisted, and the twisting directly causes the shaking of the cable 1, which may cause the cable 1 to turn over, directly affecting the winding quality;

[0051] Generally, the larger the angle β, the greater the twisting and shaking of the cable 1, and the higher the possibility of the cable 1 turning over;

[0052] 4) The new guide mechanism can effectively eliminate the shaking of the cable 1 caused by the change of the angle β when the winding mechanism 3 moves. Specifically, when the cable 1 twists, the force generated by the twisting triggers one of the two horizontally or vertically installed guide rollers 41 to rotate correspondingly, and the other guide roller 41 is followed by the reaction force of the compression spring to rotate. The two guide rollers 41 always maintain close contact with the twisted cable 1, thereby eliminating the influence of shaking and ensuring the winding quality of the flat cable 1.

[0053] The guide roller set structure can rotate at a certain angle. The guide roller 41 can rotate around the core shaft at an angle β1, and the value of β1 is β / 2. Symmetrical inclined recesses are arranged on the base 46, and the L-shaped shaft end surface of the guide roller 41 is in contact with the inclined recesses to limit the rotation angle β1 of the guide roller 41.

[0054] The compression spring 44 maintains the dynamic balance of the guide roller rotation, and the guide roller 41 that rotates is quickly reset to the normal state when it loses the rotation thrust through the compression spring 44, so that the two guide rollers 41 tightly hold the cable 1.

[0055] The flat groove wheel 5 can rotate left and right around the center of the elastic cross-shaped guide roller set 4b, and the rotation angle is set to 2.2β-2.6β, and is not greater than 60°.

[0056] The width of the wheel groove of the flat groove wheel 5 is 1.1-1.3 times the width of the flat cable 1, and the included angle of the two sides of the wheel groove is 1 times β.

[0057] After the above scheme is adopted, 1) the new guide mechanism can effectively eliminate the shaking of the cable 1 caused by the change of the angle β when the winding mechanism 3 moves, reduce the probability of the cable 1 turning over, and ensure the winding quality of the flat cable.

[0058] 2) The distance between the guide rollers of the guide roller set designed in this structure is determined by the cable 1 that passes through, so it can adapt to a variety of specifications of flat cables within a certain range. When producing different flat cables, no manual adjustment of any parts is required, and the mechanism is easy to operate.
