Description

Technical Field

[0001] This utility model relates to the field of twisting machine technology, specifically to a twisting machine that facilitates the twisting of wires. Background Technology

[0002] A doubling machine is a type of mechanical equipment used in the textile industry, mainly used to twist two or more strands of yarn together. Its working principle is based on the rotation and traction of the machine. The doubling machine mainly consists of a main machine, a yarn feeding device, a twisting device, and a take-up device.

[0003] Most existing doubling machines use lead wire devices that lack yarn tension adjustment. When the yarn tension is too loose, multiple yarns are prone to deviating from the preset path during the guiding process, resulting in messy crossing and tangling. This not only disrupts the yarn order in subsequent twisting processes but may also cause the yarn to jam due to tangling, affecting transmission efficiency. When the yarn tension is too tight, the yarn is continuously subjected to tensile force exceeding its tolerance range. Especially for finer or more brittle yarns, this can easily lead to breakage, increasing production losses. Furthermore, re-threading broken yarns requires additional time, reducing overall production efficiency. Therefore, we provide a doubling machine that facilitates lead wire adjustment. Utility Model Content

[0004] The purpose of this invention is to provide a convenient twisting machine for conductors, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A double twister for easy wire twisting includes a base, a bracket 1 fixedly installed at the top front end of the base, a bracket 2 fixedly installed at the top of the base behind the bracket 1, and a bracket 3 fixedly installed at the top rear end of the base.

[0007] A wire-laying post is fixedly installed at the top front end of the base on the front side of the bracket one, and a wire groove is opened on the top of the bracket one.

[0008] A further improvement of this utility model is that: a wire ceramic column is fixedly installed on the inner side of the second bracket at the top, a motor three is fixedly installed on the outer bottom of the second bracket, and a rotating rod is fixedly installed on the output end of the motor three. The model of the motor three is Y80M1-2.

[0009] A further improvement of this utility model is that a support frame is fixedly sleeved on the outer surface of the rotating rod, and tensioning wheels are rotatably connected to both sides of the front of the support frame.

[0010] A further improvement of the present invention is that a motor is fixedly installed at the top outer side of the bracket three, and a wire storage drum is fixedly connected to the output end of the motor. The model of the motor is HCTY132M-4L.

[0011] A further improvement of this utility model is that an extension plate is fixedly installed on the front side of the bracket three, and a limit rod is fixedly installed on the inner side of the extension plate at the top.

[0012] A further improvement of this utility model is that a second motor is fixedly installed on the outer side of the extension plate, and a lead screw is fixedly installed on the output end of the second motor. The model of the second motor is YSPM-7.5-8.

[0013] A further improvement of this utility model is that: a wire block is threadedly fitted on the outer surface of the lead screw, the upper part of the wire block is slidably fitted on the outer surface of the limiting rod, and a lead hole is opened at the top of the wire block.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] 1. This utility model provides a convenient double twisting machine for conductors. By setting up a conductor path with multiple components working together, the yarn drawn from the front feed post first passes through the conductor groove of bracket one to achieve initial regularization and parallel guidance. Then, it passes through the combination of conductor ceramic column and tension wheel of bracket two. The conductor ceramic column, with its smooth surface, greatly reduces the sliding friction of the yarn and avoids yarn wear. The tension wheels on both sides can flexibly control the yarn tension during the adjustment of the bearing frame angle by the motor three-drive rotating rod. The entire conductor process is free from messy entanglement, which not only reduces the problem of yarn breakage or wear caused by friction and uneven tension, but also provides a stable yarn state for the subsequent twisting process, ensuring the twisting quality.

[0016] 2. This utility model provides a convenient double twisting machine for conductors. In the winding stage after yarn twisting, a combination structure of motor two, lead screw, limiting rod and conductor block is set on the extension plate of bracket three. When motor two drives the lead screw to rotate, the threaded conductor block is restricted by the limiting rod and converted into reciprocating linear motion along the limiting rod. The yarn passing through the lead hole of the conductor block moves left and right synchronously. At the same time, motor one drives the storage drum to rotate at a uniform speed to generate traction force, so that the twisted yarn can be evenly wound on the surface of the storage drum. This effectively avoids the problems of local over-dense, over-sparse or pile-up that are easy to occur during the winding of traditional double twisting machines. It not only improves the space utilization of the storage drum, but also ensures the regularity of the finished yarn winding. It is easier to unwind the yarn in subsequent use and improves the overall production efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown, this utility model provides a convenient wire twisting machine, including a base 1, a bracket 2 fixedly installed at the front end of the top of the base 1, a bracket 3 fixedly installed at the top of the base 1 behind the bracket 2, a bracket 4 fixedly installed at the rear end of the top of the base 1, a wire feeding post 11 fixedly installed at the front end of the top of the base 1 in front of the bracket 2, a wire groove 21 opened at the top of the bracket 2, a wire ceramic post 31 fixedly installed at the top end of the inner side of the bracket 2, a motor 32 fixedly installed at the bottom end of the outer side of the bracket 2, a rotating rod 33 fixedly installed on the output end of the motor 32, a bearing frame 34 fixedly sleeved on the outer surface of the rotating rod 33, and tensioning wheels 35 rotatably connected to both sides of the front of the bearing frame 34.

[0026] Furthermore, when motor 32 starts, its output end drives the rotating rod 33 to rotate at a constant speed. The rotating rod 33 then drives the support frame 34, which is fixedly sleeved on its outer surface, to move synchronously, thereby adjusting the angle of the support frame 34. The tensioning wheels 35 on both sides move with it. At this time, the contact between the tensioning wheels 35 and the yarn changes, thereby adjusting the tension of the yarn.

[0027] Example 2

[0028] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a motor 41 is fixedly installed at the outer top of the bracket 3 4, a wire storage cylinder 42 is fixedly connected to the output end of the motor 41, an extension plate 43 is fixedly installed on the front side of the bracket 3 4, a limit rod 44 is fixedly installed at the top of the inner side of the extension plate 43, a motor 45 is fixedly installed on the outer side of the extension plate 43, a lead screw 46 is fixedly installed at the output end of the motor 45, a wire block 47 is threaded on the outer surface of the lead screw 46, the upper part of the wire block 47 is slidably sleeved on the outer surface of the limit rod 44, and a lead hole is opened at the top of the wire block 47.

[0029] Furthermore, the output of motor 41 drives the yarn storage drum 42 to rotate at a constant speed. The traction force generated by the yarn storage drum 42 continuously pulls the yarn, which has undergone preliminary twisting and is guided by the guide block 47, backward. Under the action of the traction force, the initially twisted yarn is further stretched and completes the final twisting process, forming a twisted yarn that meets the requirements. Finally, it is wound on the outer surface of the yarn storage drum 42. The output of motor 45 drives the lead screw 46 to rotate. Since the guide block 47 is threadedly connected to the lead screw 46, and the upper part of the guide block 47 is slidably sleeved on the limiting rod 44, the limiting rod 44 restricts the rotational freedom of the guide block 47, so that the rotational motion of the lead screw 46 is converted into the reciprocating linear motion of the guide block 47 along the limiting rod 44. The reciprocating motion of the guide block 47 drives the yarn passing through the lead hole to move left and right synchronously, ensuring that the yarn can be evenly wound on the subsequent yarn storage drum 42, avoiding the situation of local winding being too dense or too sparse.

[0030] The solution uses a PLC as the core control component. The PLC establishes a connection with motor 1 (41), motor 2 (45), and motor 3 (32) via RS-485 communication. When it is necessary to start motor 1 (41), motor 2 (45), and motor 3 (32), the PLC sends a start command to motor 1 (41), motor 2 (45), and motor 3 (32), causing motor 1 (41), motor 2 (45), and motor 3 (32) to start.

[0031] The working principle of this wire twisting machine will be explained in detail below.

[0032] like Figure 1-5As shown, in use, the multi-strand yarns to be twisted are first installed on the pay-off post 11, and then the yarns are threaded in sequence. The free ends of each strand of yarn are first introduced into the guide groove 21 at the top of the support 2. The guide groove 21 provides a limiting effect, so that the multi-strand yarns are initially aligned and kept parallel. Then, the yarns are pulled to the support 3 and passed between the tensioning rollers 35 on both sides of the support frame 34. The tensioning rollers 35 form a clamping force on the yarn, achieving initial adjustment of the yarn tension. After that, the yarns are passed around the top guide ceramic post 31. The smooth surface of the ceramic conductor post 31 effectively reduces frictional damage during yarn slippage and further adjusts the yarn direction. The yarn then passes through the conductor hole inside the conductor block 47, winding around the outer surface of the yarn storage drum 42. After yarn threading is complete, the PLC control system sends start commands to each motor. First, motor 32 starts, its output driving the rotating rod 33 to rotate at a constant speed. The rotating rod 33 then drives the support frame 34, which is fixedly sleeved on its outer surface, to move synchronously, thereby adjusting the angle of the support frame 34. The tensioning wheels 35 on both sides... As it moves, the contact between the tensioning wheel 35 and the yarn changes, thus adjusting the tension of the yarn. The PLC controls the second motor 45 to start, and the output of the second motor 45 drives the lead screw 46 to rotate. Since the guide block 47 is threadedly connected to the lead screw 46, and the upper part of the guide block 47 is slidably sleeved on the limiting rod 44, the limiting rod 44 restricts the rotational freedom of the guide block 47, so that the rotational motion of the lead screw 46 is converted into the reciprocating linear motion of the guide block 47 along the limiting rod 44. The reciprocating motion of the guide block 47 drives the yarn passing through the lead hole to move in the same direction. The yarn moves left and right to ensure that it is evenly wound on the subsequent yarn drum 42, avoiding local winding that is too dense or too sparse. At the same time, the PLC controls the motor 41 to start, and the output end of the motor 41 drives the yarn drum 42 to rotate at a constant speed. The traction force generated by the yarn drum 42 will continuously pull the yarn that has been initially twisted and guided by the conductor block 47 backward. Under the action of the traction force, the initially twisted yarn is further stretched and completes the final twisting process, forming a twisted yarn that meets the requirements, and finally wound on the outer surface of the yarn drum 42.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
