[0024] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] In the description of the present invention, it is necessary to understand that the meaning of "several" is one or more, the meaning of "more" is more than two, the meanings of "greater than", "less than", "exceed" and the like are understood as not including the number itself, and the meanings of "above", "below", "within" and the like are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0026] According to an embodiment of the present invention, a soft duct wire welding production equipment, such as Figure 1-7 As shown, it at least includes: a wire supply assembly, including a turntable 810 and a limit frame 820 arranged on the turntable 810; a wire output assembly, including a wire feeding assembly and a driving assembly, the driving assembly drives the wire feeding assembly to pull the steel wire on the limit frame 820 to unwind; a rubber strip conveying assembly, including a rotating member 840 and a pressure wheel 850, the pressure wheel 850 is used to press the rubber strip unwound on the rotating member 840 to the upper side of the steel wire; a soft air duct conveying mechanism, including a stand, a diameter adjustment assembly and a transmission assembly, the stand is provided with an inclined hole 510, the diameter adjustment assembly includes a first tensioning assembly, a second tensioning assembly and a third tensioning assembly that can slide along the inclined hole 510, the transmission assembly is used to drive the first tensioning assembly, the second tensioning assembly and the third tensioning assembly to rotate circumferentially; a welding gun 900, used to spirally weld the steel wire delivered by the wire output assembly between the rubber strip and the soft air duct.

[0027] The implementation method of the above technical solution is basically as follows: the soft air duct is limited by the diameter adjustment component so that the surface of the soft air duct remains in an extended state, that is, there are basically no wrinkles on the surface of the soft air duct, which helps to improve processing positioning. The wire supply component and the wire outlet component transmit the steel wire to the surface of the soft air duct, and at the same time, the rubber strip is transmitted to the upper side of the steel wire by the pressure wheel 850. Then the welding gun 900 melts the welding wire between the tape and the surface of the soft air duct, so that the steel wire can be fixed on the surface of the soft air duct. As the soft air duct is driven by the transmission component to continue to rotate, the steel wire fixed on the surface of the soft air duct in a spiral shape is finally obtained. The strength of the soft air duct is improved as a whole. Compared with the prior art method of manually attaching steel wires to the soft air duct one by one, the technical solution of this application can improve the degree of automation and production efficiency.

[0028] The embodiments of the present application include an embodiment in which the first tensioning assembly, the second tensioning assembly and the third tensioning assembly are all adjustable. Figure 1-6In the illustrated embodiment, the second tensioning assembly and the third tensioning assembly are disposed on both sides of the first tensioning assembly, and the second tensioning assembly and the third tensioning assembly respectively respond to the driving of the second cylinder and the third cylinder to slide along the inclined hole 510, and the size of the soft air duct that can be stretched by the first tensioning assembly, the second tensioning assembly and the third tensioning assembly and the degree of tension of the soft air duct can be adjusted by adjusting the distance between the second tensioning assembly and the third tensioning assembly relative to the first tensioning assembly.

[0029] The soft air duct in the technical solution is driven by the rotating assembly to continuously rotate along its own circumference, and the movement on the axis of the soft air duct enables the steel wire to be spirally welded on the surface of the soft air duct, which can be achieved by manually pulling the soft air duct to move horizontally or by moving the welding gun 900 horizontally. Figure 1-3 In the illustrated embodiment, the present application further includes a guide wheel for crimping on the outside of the soft air duct and a limit head 830 for guiding the steel wire toward the welding gun 900. The force applied by the guide wheel to the soft air duct has a tangential force at an angle toward one side, causing the soft air duct to move horizontally, and the limit head 830 is mainly used to limit the direction of the steel wire, causing the steel wire to pass into the gap between the rubber strip and the soft air duct for subsequent welding and fixing work. At the same time, the position selection of the limit head 830 also has a limiting effect on the pitch size of the spiral steel wire. The distance between the limit head 830 and the welding gun 900 indirectly limits the tightness of the spiraling of the steel wire on the soft air duct.

[0030] The first tensioning assembly, the second tensioning assembly and the third tensioning assembly described in the technical solution can be either an integrally formed component or a separate component. In terms of the structure of the first tensioning assembly, the second tensioning assembly and the third tensioning assembly, the present application includes at least two implementation modes: first, the first tensioning assembly, the second tensioning assembly and the third tensioning assembly are all integral, and when processing, it is only necessary to put the soft air duct on the first tensioning assembly, the second tensioning assembly and the third tensioning assembly, and then perform subsequent operations; second, the first tensioning assembly, the second tensioning assembly and the third tensioning assembly are all separate, and when processing, it is only necessary to install the soft air duct from one side of the gap between the second tensioning assembly and the third tensioning assembly. In this implementation mode, the external processing component is set at a position outside the gap, and the soft air duct arranged at the gap position during processing is processed, so that the processed part of the soft air duct and the unprocessed part can be well distinguished.

[0031] As shown in Figures 1-6, the latter embodiment in the previous section is adopted, and the stand is also set in a split type, specifically including a finished product side frame body 541 and a processing side frame body 542. Correspondingly, the finished product side frame body 541 and the processing side frame body 542 are both provided with an inclined hole 510. The split mode of the first tensioning assembly, the second tensioning assembly and the third tensioning assembly can be specifically that the first tensioning assembly includes a first arm 611 and a second arm 621 respectively mounted on the processing side frame body 542 and the finished product side frame body 541, the second tensioning assembly includes a third arm 641 and a fourth arm 642 respectively mounted on the processing side frame body 542 and the finished product side frame body 541, and the third tensioning assembly includes a fifth arm 661 and a sixth arm 662 respectively mounted on the processing side frame body 542 and the finished product side frame body 541. In order to facilitate the installation of the soft air duct, the present application preferably uses the finished side frame 541 or the processed side frame 542 to be movable, such as being slidably connected to an external frame or installed with rollers, etc., and moving it before processing to make necessary space for the soft air duct to be inserted.

[0032] On the basis of the previous embodiment, in order to perform continuous and accurate processing on the soft air duct that is translated to the position outside the gap, it is preferred that the ends of the first arm 611 and the second arm 621 are sleeved with each other, such as Figure 1-4 On the one hand, it provides support for the processing of the soft air duct in the gap to avoid collapse and wrinkling due to the soft material of the soft air duct, which is convenient for processing and positioning. On the other hand, the socket connection method also makes it convenient for the two to be separated and loaded into the soft air duct for processing.

[0033] In addition, in some embodiments of the present invention, Figure 3 , 4 In 6, the diameter adjustment assembly also includes a support block 680 installed on the processing side frame 542, and the intersection lines of the first arm 611, the third arm 641 and the fifth arm 661 with the soft air duct are all located on the cylindrical surface of the same virtual cylinder. The support block 680 has a supporting surface 681 located on the cylindrical surface. Preferably, the supporting surface 681 is arranged in the gap area to strengthen the support for the soft air duct transported to this position, so as to facilitate processing positioning.

[0034] Since the technical solution of the present application is applicable to the situation where the soft air duct needs to be processed radially, it can be used to adjust the local strength of the soft air duct, wind steel wire on the soft air duct, etc. When this processing requirement needs to be met, since the soft air duct on the processed side is attached with components with greater strength or hardness, and the length of the first tensioning assembly, the second tensioning assembly and the third tensioning assembly are limited, the space occupied by the soft air duct fully unfolded in length is large, so as the length of the soft air duct entering the second arm 621, the fourth arm 642 and the sixth arm 662 increases, the soft air ducts will be stacked with materials, and compared with the stacking of a small amount of soft soft air duct on the unprocessed side, the components with greater strength or hardness attached to the processed part make it difficult to stack each other. Therefore, in order to save the space required for processing and facilitate the stacking of the processed soft air duct parts, the diameter adjustment component installed on the processing side frame 542 is adjusted to expand the soft air duct to a greater extent than the diameter adjustment component installed on the finished side frame 541, thereby leaving a certain radial margin for the processed soft air duct, which is convenient for stacking the processed soft air duct. That is, the distance between the fourth arm 642 and the sixth arm 662 relative to the second arm 621 is smaller than the distance between the third arm 641 and the fifth arm 661 relative to the first arm 611.

[0035] According to some embodiments of the present invention, the transmission assembly includes a first servo motor 710 and a second servo motor 720 respectively mounted on the processing side frame 542 and the finished product side frame 541, the first arm 611 and the second arm 621 are directly driven by the first servo motor 710 and the second servo motor 720 respectively, the first arm 611, the third arm 641 and the fifth arm 661 are linked by the same chain, and the second arm 621, the fourth arm 642 and the sixth arm 662 are linked by the same chain, so that the radial rotation speed of the processed part of the soft air duct and the unprocessed part of the soft air duct is respectively adjusted by the second servo motor 720 and the first servo motor 710. At the same time, since the first arm 611 and the second arm 621 are sleeved, they can also be allowed to rotate relative to each other and have different rotation speeds.

[0036] Preferably, under the premise that the opening degree of the processed part of the soft air duct is smaller than that of the unprocessed part of the soft air duct, the rotation speed of the first servo motor 710 is smaller than the rotation speed of the second servo motor 720, thereby ensuring that the linear speed of the processed part of the soft air duct is consistent with the linear speed of the unprocessed part of the soft air duct, avoiding the formation of wrinkles on the soft air duct due to inconsistent linear speeds on both sides, avoiding adverse effects on the accuracy of processing positioning, and taking into account the advantages of space saving and high precision.

[0037] In some embodiments of the present invention, since the steel wire directly provided by the wire supply assembly has irregular twists and poor uniformity, it is necessary to adjust the steel wire before welding, such as Figure 7 As shown, the wire outlet assembly preferably also includes a straightening assembly, and the straightening assembly includes a drive roller 110 and a plurality of guide rollers 120, wherein the drive roller 110 is used to be crimped onto the surface of the steel wire, and the plurality of guide rollers 120 are arranged in two rows along the wire feed direction. In addition, the wire feeding assembly preferably includes a first feed roller 210 and a second feed roller 220 for being arranged on both sides of the steel wire, and the first feed roller 210 and the second feed roller 220 are both cylindrical as a whole. Since the steel wire used in the present application needs to be able to be spirally wound onto the surface of the soft air duct, it is difficult to make the steel wire fit onto the surface of the soft air duct before welding by simply adjusting the uniformity of the steel wire before welding. The present application preferably also includes a bending adjustment assembly, such as Figure 7 As shown, the bending adjustment assembly includes a frame 310, a feed rack 320, a discharge rack 330 and an adjusting wheel 340, the feed rack 320 and the discharge rack 330 are both rotatably arranged on the frame 310, the straightening assembly is arranged on the feed rack 320, the wire feeding assembly is arranged on the discharge rack 330, the adjusting wheel 340 is arranged between the feed rack 320 and the discharge rack 330, and the adjusting wheel 340 can be raised and lowered on the frame 310, so that by adjusting the angular relationship between the discharge rack 330, the feed rack 320 and the adjusting wheel 340, the bending degree of the steel wire can be pre-adjusted, so as to obtain a better fit between the steel wire and the surface of the soft air duct.

[0038] like Figure 7In the shown embodiment, both a straightening component and a bending component are included. Accordingly, the driving component includes a servo motor 410, a first sprocket and a second sprocket. The first sprocket and the second sprocket are respectively fixedly arranged at the tail of the driving roller 110 and the first feeding roller 210. The first sprocket and the second sprocket are both connected to the servo motor 410 through a chain transmission. The specific working method is as follows: the servo motor 410 transmits power to the transmission roller 110 and the first feeding roller 210 to make them rotate, and the two driven parts are in direct contact with the steel wire for transmitting the steel wire to be output by the wire feeding assembly. While the steel wire is driven by the transmission roller 110 in the straightening assembly, it is restricted by the two rows of guide rollers 120 to change from a bent state to a straight steel wire, and the straight steel wire enters the bending adjustment assembly. Since the feed rack 320, the discharge rack 330 and the adjusting wheel 340 are all arranged on the frame 310, and the feed rack 320 and the discharge rack 330 are rotatable, and the adjusting wheel 340 can be raised and lowered, the feed rack 320 and the discharge rack 330 can be pre-adjusted to a certain angle, and the position of the adjusting wheel 340 can be adjusted to the feed rack 320 and the discharge rack 330. 30, that is, the overall angle formed, the steel wire adjusted by the straightening assembly is limited by the adjusting wheel 340 and is restricted by the position of the wire feeding assembly. As the steel wire is continuously conveyed, the steel wire is bent at every location, and finally each section of the steel wire has a curvature, and the size of the curvature can be achieved by adjusting the change in the angle between the feed rack 320 and the discharge rack 330, so that a steel wire with a consistent spiral curvature can be exported at the wire feeding assembly, which is suitable for winding onto the surface of the soft air duct stretched by the first tensioning assembly, the second tensioning assembly and the third tensioning assembly, reducing the operating procedures and having better uniformity than manual bending, which is convenient for the subsequent operation of fixing the steel wire to the soft air duct with a rubber strip, and improving the output efficiency and yield rate.

[0039] The description of the implementation method in which the feed rack 320 and the discharge rack 330 are rotatable relative to the frame 310 in the above embodiments can be implemented in a variety of ways, such as detachably hingedly connecting the feed rack 320 and the discharge rack 330 to the frame 310, or rotating the feed rack 320 and the discharge rack 330 through a motor adjustment to achieve the adjustment of the angle between the discharge rack 330 and the discharge rack 330. Figure 7In the illustrated embodiment, the frame 310 is provided with two cross beams 311, and both of the cross beams 311 are provided with waist-shaped holes 312. The feed rack 320 and the discharging rack 330 are respectively fixed with straight rods 350, and the straight rods 350 are passed through the waist-shaped holes 312. The straight rods 350 are provided with threaded sections and slidable nuts 351, and the nuts 351 abut against the cross beams 311 while being tightened with the threaded sections. The specific operation method is as follows. When the angle needs to be adjusted, first screw the nut 351 so that the nut 351 is loosened relative to the threaded section and disengaged from each other, and then slide the nut 351 relative to the straight rod 350 so that the nut 351 moves along the side away from the beam 311. At this time, there is a large gap between the waist-shaped hole 312 of the beam 311 and the straight rod 350, and the radial size of the threaded section is also smaller than the waist-shaped hole 312. The feed rack 320 or the discharging rack 330 can be directly rotated to make the straight rod 350 extend and retract relative to the waist-shaped hole 312. After reaching the required position, slide the nut 351 to the waist-shaped hole 312 and tighten it onto the threaded section. Then tighten the nut 351 and the threaded section. The tightened nut 351 can abut against the beam 311 because its radial size is larger than the waist-shaped hole 312, thereby driving the feed rack 320 or the discharging rack 330 to be fixed at a certain angle relative to the beam 311.

[0040] The lifting and lowering movement of the adjusting wheel 340 can be realized by directly controlling the adjusting wheel 340 to move up and down. Figure 7 In the illustrated embodiment, the bending adjustment assembly further includes a screw rod 360 and a handwheel 370 fixedly connected to the screw rod 360, and the adjusting wheel 340 is screwed onto the screw rod 360, that is, the adjusting wheel 340 is equivalent to forming a screw rod 360 nut 351 structure with the screw rod 360. As the handwheel 370 adjusts the screw rod 360 to rotate, the adjusting wheel 340 also rises and falls accordingly, and the adjusting wheel 340 can be conveniently adjusted to the intersection of the extension surfaces of the feed rack 320 and the discharge rack 330 to help the steel wire obtain a stable curvature.

[0041] According to some embodiments of the present invention, in order to better limit the position of the steel wire to obtain a straight steel wire, a plurality of the guide rollers 120 are provided with guide grooves, and the steel wire is continuously confined in the guide grooves for transmission.

[0042] In some embodiments of the present invention, the first feed roller 210 and the second feed roller 220 are both provided with anti-slip convex patterns to increase the friction force on the steel wire and to pull the steel wire out of the wire feeding assembly.

[0043] In some embodiments of the present invention, the first feed roller 210 and the second feed roller 220 are both gears, and a gap is reserved between the first feed roller 210 and the second feed roller 220 for accommodating the passage of the steel wire, so that the first feed roller 210 and the second feed roller 220 have teeth. Compared with a smooth contact surface, the teeth can continuously rub the steel wire during the rotation of the gear, and the friction force is used to drive the steel wire to be output from the wire feeding assembly.

[0044] In some embodiments of the present invention, the driving assembly includes a servo motor 410, a first sprocket and a second sprocket, the first sprocket and the second sprocket are respectively fixedly arranged at the tail of the transmission roller 110 and the first feeding roller 210, and the first sprocket and the second sprocket are both chain-driven with the servo motor 410. Of course, the transmission method can also be belt-driven, or the transmission roller 110 and the first feeding roller 210 are not driven by the same servo motor 410, or even only the driving assembly is arranged in the wire feeding assembly, which can also achieve continuous traction of the steel wire.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
