Description

Technical Field

[0001] This utility model relates to the field of glass fiber drawing machine technology, and in particular to a multi-station, multi-variety glass fiber drawing machine. Background Technology

[0002] A glass fiber drawing machine is a mechanical device that draws molten glass into fiber filaments at high speed and winds them into fiber rolls according to a certain pattern.

[0003] Currently, mainstream fiberglass drawing machines on the market adopt a dual-spindle and dual-impeller design, switching between them via a flipping mechanism. Only one machine head can operate during drawing operations, resulting in low flow rate and low production capacity from the matching spindle. Because only one machine head operates, when producing multi-section drawn products, the spindle width must be shortened, reducing the weight of each yarn bundle. This leads to shorter drawing times, more frequent bobbin changes, increased manual labor intensity, higher labor costs, and low production efficiency, making it difficult to meet the actual production needs of enterprises. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a multi-station, multi-variety glass fiber drawing machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-station, multi-variety glass fiber drawing machine, including a frame, a base plate provided on the side of the frame, two mounting holes staggered on the base plate, a turntable provided in each of the two mounting holes, a machine head device provided on the turntable, two sets of flipping mechanisms for driving the two turntables to rotate provided in the frame, two sets of wire-blocking mechanisms and groove cylinder mechanisms respectively provided on the frame corresponding to the two machine head devices, a sliding groove horizontally provided at the lower part of the base plate, and an automatic wire-feeding mechanism slidably provided in the sliding groove.

[0006] By adopting the above technical solution, two sets of upper and lower yarn heads are installed using two mounting holes, along with a flipping mechanism, a yarn-blocking mechanism, a grooved drum mechanism, and an automatic yarn-feeding mechanism. The automatic yarn-feeding mechanism slides horizontally to cooperate with the two sets of yarn heads for loading. This allows the upper and lower sets of yarn heads to work independently, enabling the simultaneous drawing of two sets of yarn without interference. It can be adapted to high-flow spinnerets, increasing the weight of the yarn bundle and thus extending the drawing time and improving work efficiency. Furthermore, by controlling different rotation speeds of the two sets of yarn heads, two different types of yarn can be drawn simultaneously to meet the needs of multi-variety production. When one set of yarn experiences flyaways, the other set can continue drawing until the finished product is completed, and the set with flyaways can continue to be loaded and drawn. This not only increases output but also greatly reduces losses caused by flyaways.

[0007] Furthermore, the turntable has two through holes symmetrically arranged in the center, and the machine head device includes two main shaft mechanisms disposed in the two through holes, with an impeller mechanism disposed at the outer end of the main shaft mechanism.

[0008] By adopting the above technical solution, two through holes are set on the turntable, and two main shaft mechanisms and impeller mechanisms are set. In this way, the impeller mechanism can be flipped under the action of the flipping mechanism, realizing the switching between the working position and the standby position of the impeller mechanism.

[0009] Furthermore, the automatic wire feeding mechanism includes a sliding sleeve slidably disposed within a sliding groove, a sliding seat disposed on the sliding sleeve within the frame, and horizontal slide rails disposed on both sides of the sliding groove on the inner side of the base plate. The sliding seat is slidably disposed on the two horizontal slide rails by a slider. A horizontally arranged drive cylinder is also disposed within the frame, and the piston rod end of the drive cylinder is fixedly connected to the sliding seat. An auxiliary feeding component is disposed at the outer end of the sliding sleeve, and a drive component is disposed at the inner end within the frame.

[0010] By adopting the above technical solution, a sliding sleeve, a sliding seat, a horizontal slide rail, and a drive cylinder are set up. The drive cylinder drives the sliding seat to slide on the horizontal slide rail, thereby adjusting the sliding sleeve to slide in the sliding groove. In this way, the position of the auxiliary loading component can be switched, so as to cooperate with the two sets of machine head devices to assist loading.

[0011] Furthermore, the auxiliary loading assembly includes a mounting frame disposed at the outer end of the sliding sleeve, a traction plate disposed on the mounting frame, a traction groove formed on the traction plate, a traction roller assembly disposed on the mounting frame below the traction groove, a yarn guide rod rotatably disposed on the lower surface of the traction plate, and a rotating assembly for driving the yarn guide rod to rotate disposed on the upper surface of the traction plate.

[0012] By adopting the above technical solution, a mounting frame, traction plate, traction groove, traction roller group, yarn swinging rod, and rotating component are set up. The traction plate and traction groove provide a guiding path for the yarn. The yarn swinging rod swings under the driving action of the rotating component, pushing the yarn into the traction groove. The traction roller group is used to wind the yarn and cooperate with the machine head device to assist in loading the yarn.

[0013] Furthermore, the drive assembly includes a transmission sleeve disposed within a sliding sleeve, a drive motor disposed at the inner end of the transmission sleeve, and a transmission shaft rotatably disposed within the transmission sleeve. The inner end of the transmission shaft is connected to the output shaft of the drive motor via a reducer, and the outer end is connected to a traction roller assembly.

[0014] By adopting the above technical solution, a transmission sleeve, a drive motor, and a transmission shaft are set up. The drive motor drives the transmission shaft to rotate, thereby driving the traction roller group to move.

[0015] Furthermore, a baffle plate is obliquely arranged on the base plate, and an S-plate is provided on the turntable between the two main shaft mechanisms. The highest end of the baffle plate is located below the groove of the groove mechanism corresponding to the upper head device, and the lowest end is located above the S-plate on the lower turntable.

[0016] By adopting the above technical solution, a baffle plate and an S-plate are set up. The baffle plate guides the water dripping from the upper grooved cylinder mechanism to the lower S-plate and drains it out, thus preventing the water from dripping from the upper grooved cylinder mechanism onto the lower yarn and causing pollution.

[0017] In summary, this utility model has the following beneficial effects: In this application, two sets of upper and lower yarn heads are installed through two mounting holes, and are equipped with a flipping mechanism, a yarn-blocking mechanism, a grooved drum mechanism, and an automatic yarn-feeding mechanism. The automatic yarn-feeding mechanism slides horizontally to cooperate with the two sets of yarn heads for loading, thus enabling the upper and lower sets of yarn heads to work independently. This allows for simultaneous drawing of two sets of yarn without interference, and can be adapted to high-flow spindles, increasing the weight of the yarn bundle and extending the drawing time, thereby improving work efficiency. Furthermore, by controlling the different rotation speeds of the two sets of yarn heads, two different types of yarn can be drawn simultaneously to meet the needs of multi-variety production. When one set of yarn experiences flyaways, the other set can continue drawing until the finished product is completed, and the set with flyaways can continue to be loaded for drawing. This not only increases output but also greatly reduces losses caused by flyaways. Attached Figure Description

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] like Figure 1-4As shown in the illustration, this application discloses a multi-station, multi-variety glass fiber drawing machine, including a frame 10. A base plate 11 is provided on the side of the frame 10. Two mounting holes 12 are offset on the base plate 11, with the upper mounting hole 12 located to the left of the lower mounting hole 12. A turntable 20 is provided in each of the upper and lower mounting holes 12. A machine head device is provided on the turntable 20. The machine head device includes two main shaft mechanisms 70 and two impeller mechanisms 80. The main shaft mechanisms 70 drive the impeller mechanisms 80 to rotate, and the impeller mechanisms 80 are used to mount yarn bobbins and perform fiber drawing. Two sets of flipping mechanisms 30 are provided inside the frame 10 to drive the two turntables 20 to rotate. By driving the turntables 20 to rotate, the two main shaft mechanisms 70 and impeller mechanisms 80 are flipped to switch positions, realizing the switching between the working position and the standby position. The frame 10 is equipped with two sets of yarn-blocking mechanisms 40 and grooved drum mechanisms 50, respectively, on the upper and lower head devices. The yarn-blocking mechanism 40 pushes the yarn towards the front end of the impeller mechanism 80 for easy loading. The upper yarn-blocking mechanism 40 is located above the upper mounting hole 12, and the lower yarn-blocking mechanism 40 is located to the right of the lower mounting hole 12, thus avoiding interference between the two yarn-blocking mechanisms 40 during operation. The grooved drum mechanism 50 drives the yarn to reciprocate during the drawing process, facilitating yarn formation. By setting up two sets of head devices, the upper and lower head devices can work independently, allowing two sets of yarn to be drawn simultaneously without interference. This can be adapted to high-flow spindles, increasing the weight of the yarn bundle, thereby extending the drawing time and improving work efficiency. In addition, by controlling the different speeds of the two sets of machine head devices, two different types of yarn can be drawn out at the same time to meet the needs of multi-variety production; when one set of yarns produces fly filaments, the other set can continue to draw the yarn until the finished product is completed, and the set with fly filaments can continue to be put on the machine for drawing. This not only increases the output, but also greatly reduces the losses caused by fly filaments.

[0025] Specifically, two through holes 21 are symmetrically opened on the turntable 20, and two main shaft mechanisms 70 are respectively installed in the two through holes 21, and the impeller mechanism 80 is installed on the outer end of the main shaft mechanism 70.

[0026] A sliding groove 13 is horizontally formed at the lower part of the substrate 11, and an automatic wire feeding mechanism 60 is slidably disposed within the sliding groove 13. The automatic wire feeding mechanism 60 includes a sliding sleeve 61 slidably disposed within the sliding groove 13, a sliding seat 62 disposed on a section of the sliding sleeve 61 located inside the frame 10, and horizontal slide rails 14 disposed on both sides of the sliding groove 13 on the inner side of the substrate 11. The sliding seat 62 is slidably disposed on the two horizontal slide rails 14 by a slider, thereby driving the sliding sleeve 61 to slide within the sliding groove 13 by sliding the sliding seat 62 on the horizontal slide rails 14. A horizontally arranged drive cylinder 63 is also disposed within the frame 10, and the piston rod end of the drive cylinder 63 is fixedly connected to the sliding seat 62, that is, the extension and retraction of the piston rod of the drive cylinder 63 drives the sliding seat 62 to slide on the horizontal slide rails 14.

[0027] An auxiliary loading assembly 64 is provided at the outer end of the sliding sleeve 61, and a drive assembly 65 is provided at the inner end within the frame 10. The auxiliary loading assembly 64 assists the impeller mechanism 80 in loading, and includes a mounting frame 641 at the outer end of the sliding sleeve 61. A traction plate 642 is provided on the mounting frame 641, and a traction groove 643 is formed on the traction plate 642. The traction plate 642 and the traction groove 643 provide a guiding path for the yarn. A traction roller group 644 is provided on the mounting frame 641 below the traction groove 643. The traction roller group 644 is used to wind the yarn and assist the machine head device in loading. A yarn-guiding swing rod 645 is rotatably provided on the lower surface of the traction plate 642, and a rotating assembly 646 is provided on the upper surface of the traction plate 642 to drive the swing rod 645 to rotate. The swing rod 645 swings under the drive of the rotating assembly 646, pushing the yarn into the traction groove 643.

[0028] The drive assembly 65 is used to drive the traction roller group 644 to rotate. It includes a transmission sleeve 651 disposed within a sliding sleeve 61. A drive motor 652 is disposed at the inner end of the transmission sleeve 651. A drive shaft (not shown in the figure) is rotatably disposed within the transmission sleeve 651. The inner end of the drive shaft is connected to the output shaft of the drive motor 652 through a reducer 653, and the outer end is connected to the traction roller group 644. The drive motor 652 drives the drive shaft to rotate through the reducer 653, thereby driving the traction roller group 644 to rotate and wind the yarn onto the traction rollers for auxiliary loading.

[0029] A further configuration includes a baffle plate 15 obliquely arranged on the base plate 11, and an S-plate 22 positioned on the turntable 20 between the two main shaft mechanisms 70. The highest point of the baffle plate 15 is located below the groove of the groove mechanism 50 corresponding to the upper head assembly, and the lowest point is located above the S-plate 22 on the lower turntable 20. The baffle plate 15 guides the water dripping from the upper groove mechanism 50 to the lower S-plate 22 and drains it away, preventing the water from dripping onto the lower yarn and causing contamination.

[0030] The operating principle of a multi-station, multi-variety glass fiber drawing machine in this embodiment is as follows: During the drawing process, the yarn is first divided into two strands by the bundling mechanism above the drawing machine. The upper yarn-blocking mechanism 40 pushes one strand of yarn to the front end of the upper impeller mechanism 80. The automatic yarn-feeding and loading mechanism 60 is located at the leftmost position, assisting the upper impeller mechanism 80 in loading the yarn. After loading, the upper impeller mechanism 80 begins the drawing process. Then, the lower yarn-blocking mechanism 40 pushes the other strand of yarn to the front end of the lower impeller mechanism 80. The piston rod of the drive cylinder 63 drives the sliding seat 62 to slide, causing the sliding sleeve 61 to slide to the rightmost end, assisting the lower impeller mechanism 80 in loading the yarn. After loading, the lower impeller mechanism 80 begins the drawing process. In this way, the upper and lower impeller mechanisms 80 can work together without interfering with each other, greatly improving the drawing efficiency.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
