Description

Technical Field

[0001] The invention relates to the technical field of coated wire collection, in particular to a tension self-adapting mechanism of a winding device of a coated wire machine. Background Art

[0002] In the winding process of the coated yarn machine, the change of tension is a key variable, which directly affects the winding effect and the quality of the final product. If the tension is too small, the winding may not be tight and compact. When storing or transporting, the coated yarn is easy to loosen and fall off the parallel bobbin; if the tension is too large, the friction between the coated yarn and the transmission mechanism will increase, which will easily wear off the coated yarn or even tear it directly. One of the most important variables is the change in the winding and unwinding diameter. As the winding diameter increases, if the rotation speed remains unchanged, the winding process will be subjected to greater tensile force, thereby increasing the tension. Therefore, it is necessary to adjust the tension to a certain extent to avoid the increase in tension on the yarn as the winding diameter increases. At the same time, it is also necessary to maintain the effect of tension to avoid the coated yarn from being loosely wound. Based on this problem, improvements to facilitate winding are proposed.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-6 The present invention provides a technical solution: a tension adaptive mechanism of a winding device of a coated wire machine, comprising an outer shell 1 for support on both sides, and between the outer shells 1 on both sides are provided:

[0029] The winding part 4 is connected between the outer shells 1 on both sides and is used to wind up the coated wire. The upper and lower sides of the winding part 4 can expand outwards as the diameter of the wound coated wire changes.

[0030] The transmission part 5 is also connected between the outer shells 1 on both sides, and the transmission part 5 is used to support the coated wire;

[0031] The transmission part 5 is in the shape of multiple shafts, and is staggered up and down. The staggered distribution is used to increase the resistance during the transmission of the coated wire.

[0032] Box frames 2 are fixed to both inner and outer sides of the outer shell 1 on one side, and a servo motor 3 is fixed to the outer side of the box frame 2 on one side. The servo motor 3 is used to control the rotation of the winding part 4, and the winding part 4 winds the coated wire.

[0033] The winding section 4 includes two sets of extrusion shafts 42, one set of rotating shafts 41 and two sets of longitudinal plates 43;

[0034] The rotating shaft 41 is rotatably arranged between two groups of longitudinal plates 43. One group of longitudinal plates 43 is fixed to the outer shell 1 on one side, and the other group of longitudinal plates 43 is fixed to the inner box frame 2. One end of the rotating shaft 41 is provided with a gear and extends into the box frame 2 on one side. The gear end of the rotating shaft 41 is connected to the servo motor 3 through a gear set. Under the action of the servo motor 3, the rotating shaft 41 is rotated, and the rotating shaft 41 is limited between the two groups of longitudinal plates 43.

[0035] Two groups of extrusion shafts 42 are also arranged between the two groups of longitudinal plates 43. The two groups of extrusion shafts 42 are respectively located on the upper and lower sides of the rotating shaft 41. The two groups of extrusion shafts 42 can be slid up and down and are used to extrude the coated wire wound on the rotating shaft 41. The two groups of extrusion shafts 42 slide between the two groups of longitudinal plates 43 and are extruded with the rotating shaft 41. When the rotating shaft 41 rotates, the two groups of extrusion shafts 42 are driven to rotate to extrude the coated wire.

[0036] The ends of the two groups of extrusion shafts 42 penetrate the longitudinal plates 43 on both sides, and the two groups of extrusion shafts 42 and the longitudinal plates 43 are slidably clamped. One end of the two groups of extrusion shafts 42 is fixed with a detachable connecting end 421, and the two connecting ends 421 are sleeved with a transmission belt 422;

[0037] The transmission part 5 includes a plurality of transmission shafts 51, which are rotatably arranged between the outer shells 1 on both sides, and the plurality of transmission shafts 51 are staggered in an upper and lower manner, wherein the end of the innermost transmission shaft 51 is rotatably connected with a bearing end 52, and the outer sides of the outer shells 1 on both sides are provided with an inclined groove 11, and the bearing end 52 is slidably arranged in the inclined groove 11, and a support frame 53 is also fixed to the outer side of the outer shells 1 on both sides, and a support spring 54 is fixed between the support frame 53 and the bearing end 52, and the support spring 54 is used to squeeze the bearing end 52 to the end of the inclined groove 11, and the transmission belt 422 also sleeves the transmission shaft 51 with the bearing end 52, and the transmission belt 422 is in a tightened setting, and after the two groups of extrusion shafts 42 move outward, the compression of the support spring 54 is realized, and the transmission shaft 51 with the bearing end 52 is away from other transmission shafts 51;

[0038] Under the action of the transmission belt 422, the extrusion shaft 42 rotates to drive the transmission shaft 51 to rotate, so that when the extrusion shaft 42 moves outward, the support spring 54 is in an extrusion state, and at the same time, the innermost transmission shaft 51 is pulled away from other transmission shafts 51, reducing the bending degree of the transmitted coated wire;

[0039] In addition, as the diameter of the rotating shaft 41 and the coated wire gradually increases, the squeezing degree of the support spring 54 gradually increases, so that the squeezing degree of the squeezing shaft 42 and the coated wire with increased diameter increases, that is, the coated wire is more securely wound to avoid looseness.

[0040] The outer wall of the extrusion shaft 42 is made of rubber material, and the outer wall of the extrusion shaft 42 is squeezed with the outer wall of the rotating shaft 41. The rotation of the rotating shaft 41 drives the two groups of extrusion shafts 42 to rotate. The rubber material is easier to generate movement, which is used to increase resistance.

[0041] A transmission ring 512 is sleeved on the transmission shaft 51, and a slideway for clamping the coating is provided on the outer side of the transmission ring 512. The transmission ring 512 can slide along the axial direction of the transmission shaft 51 to prevent the coated wire from directly contacting the transmission shaft 51. Relatively speaking, the coated wire can maintain transmission without generating other friction forces, thereby reducing the possibility of breakage.

[0042] A limited position path 511 is provided on the outer wall of the transmission shaft 51, and a rotatable ball 513 is embedded on the inner side of the transmission ring 512. The ball 513 is slidably arranged in the limited position path 511, so that the transmission shaft 51 drives the transmission ring 512 to rotate, and also avoids affecting the sliding of the transmission ring 512. The ball 513 is used to realize rolling friction during the sliding process of the transmission ring 512, thereby reducing the friction effect to the greatest extent.

[0043] The detachable connecting end 421 is threadedly matched with the extrusion shaft 42 . The diameter of the connecting end 421 is different from the diameter of the extrusion shaft 42 , so that the rotation speed of the transmission shaft 51 is different from the linear speed of the rotation of the rotating shaft 41 .

[0044] The working principle of the present invention is as follows: the coated wire is passed through multiple transmission shafts 51 and then wound onto the rotating shaft 41. Under the action of the servo motor 3, the rotating shaft 41 is driven to rotate to reel the coated wire. The multiple transmission shafts 51 are staggered to increase the resistance of the coated wire during transmission.

[0045] Firstly, the coated wire is wound onto the rotating shaft 41, so that the diameter of the rotating shaft 41 plus the coated wire increases, and the extrusion shafts 42 on the upper and lower sides are driven to move outward along the longitudinal plate 43. Since the overall length of the transmission belt 422 remains unchanged, the innermost transmission shaft 51 can be driven to move along the inclined groove 11, so that the transmission shaft 51 is away from other transmission shafts 51, and the spacing between the staggered transmission shafts 51 is relatively far away, so that the degree of bending transmission of the coated wire changes, and the bending angle of the smaller coated wire is smaller. When the rotation speed of the rotating shaft 41 remains unchanged, the diameter increases, the linear speed increases, and the bending angle of the coated wire decreases, and the resistance decreases, so that the tension of the coated wire can be adjusted to avoid the breakage of the coated wire.

[0046] Secondly, since the extrusion shaft 42 is extruded by the rotating shaft 41, the extrusion shaft 42 is driven to rotate during the rotation of the rotating shaft 41, and the transmission belt 422 drives the transmission shaft 51 to rotate, so that the coated wire passing through the transmission shaft 51 is subjected to the tension, and the tension wound on the rotating shaft 41 can be controlled. As the diameter of the rotating shaft 41 plus the coated wire increases, the rotation speed of the extrusion shaft 42 can also be controlled to increase, and the rotation speed of the transmission shaft 51 also increases, so that the tension is relatively controlled;

[0047] Secondly, the connecting end 421 can be disassembled and replaced with different diameters. When the extrusion shaft 42 rotates, the linear speed of the connecting end 421 is different from the linear speed of the extrusion shaft 42. When the length of one rotation of the extrusion shaft 42 is greater or less than the length of one rotation of the connecting end 421, the linear speed of the transmission shaft 51 is also changed, thereby changing the transmission effect of the coated wire and adjusting the tension of the coated wire.

[0048] Thirdly, the transmission ring 512 can be driven to rotate by the transmission shaft 51, and can slide along the axis of the transmission shaft 51, and it is rolling friction. In the process of winding the coated wire, it is necessary to make the coated wire move back and forth and be evenly wound on the rotating shaft 41, and the transmission ring 512 moves along the transmission shaft 51, which reduces the friction to the greatest extent, and relatively makes the coated wire in transmission in a plane, reducing the possibility of the coated wire breaking, and also makes the coated wire easy to move along the axial direction of the transmission shaft 51 and be more evenly wound on the rotating shaft 41.
