Description

Technical Field

[0001] The present invention relates to the technical field related to the production of covered yarn, and specifically to a covered yarn conveying mechanism with a material guiding structure and a conveying method. Background Technique

[0002] Covered yarn, also known as wrapped yarn, is a new type of yarn structure. It uses a filament or staple fiber as the core yarn, and another filament or staple fiber yarn is wrapped around it. The outer wrapping yarn wraps the core yarn in a spiral manner. Its characteristics are even yarn evenness, plumpness, smooth yarn with less hairiness, high strength, and few broken ends.

[0003] During the conveying and winding process of covered yarn, it is necessary to evenly arrange the covered yarn on the winding roller. Therefore, a material guiding device needs to be set on the conveying device, which can change the position of the covered yarn during winding. The existing material guiding mechanism for covered yarn during conveying uses a rocker that swings left and right. This kind of material guiding mechanism can only swing left and right and cannot move as the thickness of the covered yarn on the winding roller increases. Therefore, it will affect the winding order of the covered yarn and the winding force, and affect the product quality.

[0004] Therefore, we need a covered yarn conveying mechanism with a material guiding structure to meet the requirements in the production of covered yarn. Summary of the Invention

[0005] The purpose of the present invention is to provide a covered yarn conveying mechanism with a material guiding structure and a conveying method to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A covered yarn conveying mechanism with a material guiding structure, including a mounting plate. On the upper side of the mounting plate, a winding device, a longitudinal guiding rod, and a height adjusting device are sequentially and fixedly installed. A material guiding device is slidably installed at the upper end of the longitudinal guiding rod.

[0007] The material guiding device includes a sliding bracket, which is slidably connected to the longitudinal guiding rod. A reciprocating lead screw is rotatably installed in the middle of the sliding bracket, and a transverse guiding rod is fixedly installed. A slider is movably installed on the outer sides of the middle parts of the reciprocating lead screw and the transverse guiding rod. A material guiding tube is fixedly installed on the upper side of the slider. One end of the reciprocating lead screw penetrates through the sliding bracket and is fixedly connected to the power output shaft of the material guiding motor. By setting the reciprocating lead screw, the material guiding mechanism on the material guiding device can slide left and right along the transverse guiding rod, so that the covered yarn is evenly wound on the winding device. By setting the material guiding tube, the covered yarn can be guided to wind on the winding device along a set track.

[0008] The height adjustment device includes an adjustment rod. A runner is rotatably installed at one end of the adjustment rod. The other end of the adjustment rod is rotatably connected to a mounting plate through a hinge seat. A first spring is fixedly connected to the lower side of the middle part of the adjustment rod. The lower end of the first spring is fixedly connected to the mounting plate. A driving device is movably connected to the lower part of the adjustment rod. By providing the runner, the sliding friction between the upper end of the adjustment rod and the sliding bracket can be changed into rolling friction, so as to facilitate the sliding bracket to slide along the longitudinal guide rod.

[0009] In a further embodiment, the driving device includes a mounting seat. A cam is rotatably installed on the upper part of the mounting seat. A transmission is arranged on one side of the mounting seat. The power output end of the transmission is rotatably connected to the cam through a transmission device. The power input end of the transmission is fixedly connected to the power output end of an adjustment motor. The outer side of the cam is in contact with the bottom side of the adjustment rod. By providing the cam, the adjustment rod can be adjusted slowly and evenly. There is a side surface along the radial direction of the cam and it is parallel to the radial direction of the cam. When the cam rotates, the right end of the adjustment rod can quickly fall from the highest point to the lowest point, and thus the sliding bracket can be quickly reset.

[0010] In a further embodiment, the winding device includes a fixing plate. The fixing plate is fixedly connected to the mounting plate. A winding motor is fixedly installed on one side of the upper part of the fixing plate. The power output end of the winding motor penetrates through the fixing plate and is fixedly connected to a winding roller. The winding roller is frustum-shaped. By setting the winding roller as frustum-shaped, it is convenient for the winding rod to be inserted onto the winding roller, and thus it is convenient for the loading and unloading of the winding rod.

[0011] In a further embodiment, a conveying device is fixedly installed on the upper side of one end of the mounting plate away from the winding device. The conveying device includes a connecting seat. One end of the upper side of the connecting seat is fixedly installed with a connecting plate. A speed measuring wheel is rotatably installed on one side of the connecting plate and a speed measuring motor is fixedly installed on the other side. The power input end of the speed measuring motor is fixedly connected to the speed measuring wheel. The other end of the upper side of the connecting seat is fixedly installed with a wire stabilizer.

[0012] In a further embodiment, the wire stabilizer includes a mounting frame. The mounting frame is fixedly connected to the connecting seat. A transverse roller and a longitudinal roller are rotatably installed in the inner cavity of the mounting frame.

[0013] In a further embodiment, the speed measuring wheel, the wire stabilizer and the height adjustment device are in the same vertical plane.

[0014] In a further embodiment, the rotating wheel contacts the middle part of the bottom side of the sliding bracket, the transmission device adopts a synchronous belt and a synchronous wheel, and the two ends of the guide tube are trumpet-shaped. By setting a synchronous belt and a synchronous wheel, the rotation angle of the cam can be accurately controlled, and a larger torque can be applied to the cam to prevent slipping when the force is too large.

[0015] In a further embodiment, the winding device has a fixed plate, and the fixed plate is fixedly connected to the mounting plate, a winding motor is fixedly installed on one side of the upper portion of the fixed plate, a power output end of the winding motor passes through the fixed plate and is fixedly connected to an active winding cone, a sliding groove is opened at one end of the fixed plate, a sliding plate is slidably installed in the sliding groove, a driven winding cone is rotatably installed on the middle portion of the upper end of the sliding plate, and a second spring is fixedly installed between the middle portion of the lower end of the sliding plate and the fixed plate, and by arranging the sliding plate and the winding cone, the installation and disassembly of the winding rod can be facilitated, and at the same time, it can also ensure that the winding rod is more stably installed on the winding device.

[0016] Preferably, a conveying method based on the above-mentioned coated yarn conveying mechanism with a material guide structure comprises the following steps:

[0017] A1. First, pass the covered yarn through the speed measuring wheel, then through the wire stabilizer and the material guide tube, and finally wind it on the winding roller. At this time, the transmission device drives the cam to rotate so that the wheel on the adjusting rod is in the lowest position, and then the material guide device is also in the lowest position.

[0018] A2. Start the winding motor, the material guide motor and the transmission device at the same time. The winding roller rewinds the covered yarn under the drive of the winding motor. The material guide tube reciprocates left and right under the action of the material guide motor and the reciprocating screw rod, driving the covered yarn to be evenly wound on the winding roller. The transmission device drives the cam to rotate, and then pushes the adjusting rod so that the adjusting rod pushes the material guide device to slowly rise along the longitudinal guide rod to ensure that the material guide tube and the uppermost covered yarn on the winding roller are in the same plane.

[0019] A3. By recording the speed of the covered yarn on the speed measuring wheel, we can know the length of the covered yarn wound on the winding roller. When the set length is reached, the equipment stops transmitting. At this time, the cam also rotates one circle, and the adjusting rod drives the material guide device back to the lowest position. Then, after replacing the winding roller, the transmission continues.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention relates to a covering yarn conveying mechanism and a conveying method with a material guiding structure, which can stably wind the covering yarn, adjust the height of the covering yarn during the winding process, so that the covering yarn is always in the same horizontal plane as the covering yarn on the upper side of the winding roller, and after one winding is completed, the material guiding device can be quickly restored to the lowest position to facilitate subsequent winding, effectively improving the production efficiency of the covering yarn and the product quality. By setting a reciprocating lead screw, the material guiding mechanism on the material guiding device can slide left and right along the transverse guide rod, so that the covering yarn is evenly wound on the winding device. By setting a cam, the adjusting rod can be slowly and evenly adjusted. There is a side surface along the radial direction of the cam, and the radial direction of the cam is parallel. When the cam rotates, the right end of the adjusting rod can quickly fall from the highest point to the lowest point, and thus the sliding bracket can be quickly reset.
