Description

Technical Field

[0001] This invention relates to the field of glass fiber manufacturing equipment technology, specifically to a wire drawing mechanism and a drawing machine using the same. Background Technology

[0002] Currently, fiberglass drawing machines are divided into two main categories—direct yarn drawing machines and packaged yarn drawing machines. The main difference lies in the yarn feeding method. Direct yarn drawing machines use a cam-type yarn feeding box, where the guide plate reciprocates linearly along the linear guide rail of the yarn feeding box under the push of the cam. Packaged yarn drawing machines use steel wire feeding, where the yarn slides from the high end to the low end of the feeding wire under tension, thus achieving left and right oscillation. Some equipment manufacturers also design universal drawing machines that can interchange between the two models, but these still require changing different yarn feeders to achieve functional interchangeability.

[0003] The design of two wire-laying methods for fiberglass drawing machines is a mature technology, but it also has some inherent drawbacks. When using steel wire for bundled yarn production, sliver formation occurs and cannot be completely eliminated; this phenomenon becomes more pronounced with increasing bundle numbers. Cam-type wire layers are complex and bulky, with large clearances between the cam and slider, and between the slider and linear guide, resulting in significant wear at contact points. This leads to frequent and prolonged downtime, severely impacting production efficiency. Furthermore, cam-box type wire layers lack sufficient control precision, especially with increasing wear after use, resulting in various quality problems such as uneven yarn, spiderweb-like yarn, and inconsistent yarn width. These issues range from affecting yield to causing significant performance degradation in large batches of products. The high material and processing requirements of the wire-laying cams, along with heat treatment and secondary processing after machining, contribute to high manufacturing costs. Moreover, the cam structure has a single reciprocating stroke, making product adjustments inflexible and significantly limiting customer usability.

[0004] Therefore, this invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a wire drawing mechanism and a wire drawing machine using the same, so as to solve the technical problems existing in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a yarn laying mechanism, comprising: a linear motor, wherein the linear motor is composed of a motor body and one or more motor movers; each motor mover is connected to one or more yarn guide plates, and each motor mover is individually controlled to reciprocate along a linear slide rail on the motor body.

[0007] In an optional embodiment, the linear motor is a linear motor module or a rod-shaped motor module.

[0008] In an optional embodiment, when there are two or more motor actuators, the stroke, speed, and frequency of each motor actuator's reciprocating motion along the linear slide rail are set individually.

[0009] In an optional embodiment, when there is one motor mover, the motor mover is connected to one or more of the yarn guide plates; one motor mover is connected to multiple yarn guide plates to produce multiple yarn spools of the same width.

[0010] In an optional embodiment, when there are two or more motor movers, each motor mover is connected to one yarn guide plate, and the multiple motor movers drive the yarn guide plates connected to them to produce multiple yarn balls of different widths.

[0011] In an optional embodiment, the yarn guide plate is provided with one or more yarn discharge grooves, and the yarn guide plate with two or more yarn discharge grooves is used to produce bundled yarn.

[0012] On the other hand, this embodiment of the invention also provides a wire drawing machine that uses the wire laying mechanism described above.

[0013] On the other hand, this embodiment of the invention also provides a method for using the wire drawing machine as described above, including the following steps:

[0014] S1: The molten glass flows out of the baffle plate and is rapidly cooled into wires, which are then lubricated, coated and integrated into wire harnesses.

[0015] S2: Several groups of the wire bundles coming down from above are wound onto the winding head of the drawing machine. The wire laying mechanism is close to the winding head, and the several groups of wire bundles are respectively inserted into the corresponding yarn guide plates.

[0016] S3: After a roll of raw yarn is fully loaded, the yarn laying mechanism moves laterally to the side away from the winding head, the yarn bundle leaves the yarn guide plate, and the drawing machine replaces the empty winding head;

[0017] S4: The wire harness begins to be wound around the empty winding head, repeating the action of S2, and so on;

[0018] S5: When a wire breaks or other situation occurs, the wire drawing machine stops operating.

[0019] In an optional embodiment, in step S2, multiple yarn guide plates are arranged according to the programmed method of the yarn laying mechanism under the drive of the same motor actuator.

[0020] Alternatively, multiple yarn guide plates, driven by their respective motor actuators, produce yarn bobbins of different widths according to a pre-set program.

[0021] In an optional embodiment, the yarn winding mechanism changes the yarn's looseness and density by altering the stroke during the process and the speed and frequency changes throughout the entire stroke, and by setting the winding ratio in segments when making direct yarn.

[0022] The beneficial effects of this invention are as follows:

[0023] This yarn guiding mechanism uses a linear motor module (linear motor or rod motor) as the drive structure to replace the complex cam box drive structure in the existing technology, which improves the running accuracy of the yarn guide plate. The motor stator can run according to the preset stroke, speed and frequency, and can produce yarn spools of different widths and densities at the same time. It effectively eliminates the front unevenness and side spider web of the yarn spool. The design is lightweight, and compared with the complex cam box drive structure, a single set of yarn guide plates can reduce energy consumption by more than 30%. Attached Figure Description

[0037] Example 1

[0038] Please see the appendix Figure 1-6 The purpose of this embodiment is to provide a yarn-laying mechanism, including: a linear motor, which consists of a motor body 1 and one or more motor actuators 2; each motor actuator 2 is connected to one or more yarn guide plates 3, and each motor actuator 2 is individually controlled to reciprocate along a linear slide rail on the motor body 1. Preferably, the linear motor is a linear motor module or a rod-shaped motor module. Using a linear motor as a driver ensures precise direction of movement of the yarn guide plates 3. Using the aforementioned linear motor reduces the clearance in the yarn-laying mechanism, resulting in more precise position control, better yarn formation, and no deformation.

[0039] In one embodiment, there is one motor mover 2, which is connected to one or more yarn guide plates 3. One motor mover 2 connects to multiple yarn guide plates 3 to produce multiple yarn bundles of the same width. Each yarn guide plate 3 has one or more yarn discharge grooves, and a yarn guide plate 3 with two or more yarn discharge grooves is used to produce bundled yarn. By controlling the stroke of the motor mover 2, the width of the yarn bundle is controlled. Connecting multiple yarn guide plates 3 produces multiple yarn bundles of the same width, and the density of the yarn bundles can be controlled, effectively eliminating unevenness on the front and spiderweb-like structures on the sides of the yarn bundles.

[0040] In another embodiment, there are two or more motor movers 2, and the stroke, speed, and frequency of the reciprocating motion of each motor mover 2 along the linear slide rail are set independently. There are two or more motor movers 2, and each motor mover 2 is connected to a yarn guide plate 3. Multiple motor movers 2 drive the yarn guide plates 3 connected to them to produce multiple yarn spools of different widths. Similarly, the density of the yarn spools can be controlled, effectively eliminating the unevenness on the front and the spider web on the side of the yarn spools.

[0041] As mentioned above, this yarn-laying mechanism has a long service life and does not require regular downtime for maintenance or replacement of wear parts, greatly reducing downtime and increasing output. It should be noted that this mechanism uses a linear motor module, which can be set to any width. Adjustments can be made to address the issue of yarn widths becoming too long for different yarn types. Furthermore, the width can be customized according to customer needs. It also ensures good forming, prevents unwinding and slippage, and maintains uniform yarn width.

[0042] Please see the appendix Figure 7-8 The existing yarn winding mechanism uses a complex cam box drive structure, including a yarn guide plate 71, a linear guide rail 72, a cam guide rail 73, a yarn guide plate 81, a linear guide rail 81, a linear slider 83, a bushing 84, a spiral slider 85, and a cam guide rail 86. The yarn guide plate 81 runs under the drive of the cam. The spiral slider 85 of the yarn guide plate 81 is prone to wear during the process of cooperating with the cam guide rail 86, which causes the yarn guide plate 81 to fluctuate irregularly after running for a period of time. The yarn bundle is prone to unevenness, spider webs, and uneven density.

[0043] Example 2

[0044] Please see the appendix Figure 1-6 The purpose of this embodiment is to provide a drawing machine that, using the winding mechanism described above, can simultaneously produce yarns of different widths and numbers, increasing the flexibility of production adjustments. Through program design, the stroke changes from the initial to the final process, as well as the speed changes throughout the entire process, can be implemented. When producing direct yarn, the winding ratio can be set segmentally in both the axial and radial directions. It can also be designed to be made into a yarn cake shape. Especially in the radial and axial directions, the winding ratio can be adjusted in real time.

[0045] Example 3

[0046] Please see the appendix Figure 1-6 The purpose of this embodiment is to provide a method for using the wire drawing machine as described above, including the following steps:

[0047] S1: The molten glass flows out of the baffle plate and is rapidly cooled into wires, which are then lubricated, coated and integrated into wire harnesses.

[0048] S2: Several sets of wires coming down from above are wound onto the winding head of the drawing machine. The wire laying mechanism approaches the winding head, and the several sets of wires are respectively inserted into the corresponding yarn guide plates 3.

[0049] In S2, multiple yarn guide plates 3 are arranged according to the program setting method of the yarn laying mechanism under the drive of the same motor mover 2;

[0050] S3: After a roll of raw yarn is fully loaded, the yarn laying mechanism moves laterally to the side away from the winding head, the yarn bundle leaves the yarn guide plate 3, and the drawing machine replaces the empty winding head;

[0051] S4: Start winding the wire harness on the empty winding head, repeat the action of S2, and so on;

[0052] S5: The wire drawing machine stops operating when wire breakage or other issues occur.

[0053] It should be noted that the winding mechanism changes the looseness and density of the yarn by altering the stroke during the process and the speed and frequency changes throughout the stroke, thus setting the winding ratio in segments when making direct yarn.

[0054] Example 4

[0055] Please see the appendix Figure 1-6 The purpose of this embodiment is to provide a method for using the wire drawing machine as described above, including the following steps:

[0056] S1: The molten glass flows out of the baffle plate and is rapidly cooled into wires, which are then lubricated, coated and integrated into wire harnesses.

[0057] S2: Several sets of wires coming down from above are wound onto the winding head of the drawing machine. The wire laying mechanism approaches the winding head, and the several sets of wires are respectively inserted into the corresponding yarn guide plates 3.

[0058] Multiple yarn guide plates 3, driven by their respective motor movers 2, produce yarn bobbins of different widths according to a pre-set program.

[0059] S3: After a roll of raw yarn is fully loaded, the yarn laying mechanism moves laterally to the side away from the winding head, the yarn bundle leaves the yarn guide plate 3, and the drawing machine replaces the empty winding head;

[0060] S4: Start winding the wire harness on the empty winding head, repeat the action of S2, and so on;

[0061] S5: The wire drawing machine stops operating when wire breakage or other issues occur.

[0062] In this embodiment, the yarn winding mechanism changes the winding ratio in segments when making direct yarn by changing the stroke during the process and the speed and frequency changes throughout the entire stroke, thereby changing the looseness and density of the yarn.

[0063] Using the yarn laying mechanism in the above embodiments can effectively prevent unwinding and looping, effectively eliminate end-face cobweb yarn, and effectively improve the uniformity of yarn bandwidth, as shown in Appendix Tables 1-3 below.
