Description

Technical Field

[0001] This utility model relates to the field of fiber drawing machine technology, and in particular to a glass fiber drawing machine with automatic doffing. Background Technology

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

[0003] During the fiberglass drawing process, a large amount of yarn accumulates at the front end of the winding mechanism of the drawing machine. After the drawing is completed, the yarn needs to be removed. However, the current machines cannot automatically remove the yarn, requiring manual removal, which not only affects production efficiency but also increases the workload of workers. Utility Model Content

[0004] To solve the above problems, this utility model provides an automatic doffing glass fiber drawing machine.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic doffing glass fiber drawing machine, comprising a frame, a base plate, a wire-blocking mechanism, a traction positioning mechanism, a flipping mechanism, a main shaft mechanism, and an impeller mechanism, wherein a fixed plate is provided at the outer end of the impeller mechanism, a mounting frame is provided on the base plate, a winding ring is provided on the outer surface of the fixed plate, an annular baffle is provided on the outer side of the winding ring, a broken wire ring is provided on the outer edge of the fixed plate, the broken wire ring is provided with several square grooves spaced circumferentially, the height of the ring wall of the broken wire ring located between two adjacent square grooves gradually increases along the rotation direction of the winding wheel of the drawing machine, two square notches are symmetrically opened on the baffle, the square notches penetrate the winding ring to the fixed plate, an electric cylinder is provided at the front end of the mounting frame, the piston rod end of the electric cylinder faces the center of the winding ring and is provided with a knife holder, a cutting blade is provided on the knife holder, and the cutting blade is located in the length direction of the piston rod of the electric cylinder.

[0006] By adopting the above technical solution, and setting up a fixed plate, winding ring, broken wire ring, square notch, mounting frame, electric cylinder, and cutting blade, the glass fiber drawing machine allows the glass fiber yarn to fall from the spool plate during the drawing process. Under the action of the traction and positioning mechanism, the yarn moves along the winding ring to the square notch. The rotation of the winding wheel drives the annular fixed plate and broken wire ring to rotate, and the square groove winds the yarn onto the winding ring, resulting in a high yarn grabbing success rate. When the drawing machine completes the drawing work and needs to clean the yarn wound on the winding ring, the impeller mechanism rotates, driving the winding ring to rotate and adjusting the two square notches to the length direction of the electric cylinder piston rod. Then, the electric cylinder pushes the blade holder and cutting blade towards the winding ring until they reach the square notch. The electric cylinder then drives the cutting blade to reciprocate at the square notch, cutting the yarn wound on the winding ring and detaching it from the winding ring. This process does not require manual intervention, greatly reducing the labor intensity of workers and improving production efficiency.

[0007] Furthermore, a square hole is provided on the winding ring corresponding to the square groove, a push plate is provided on the outer end of the fixed plate, and a yarn pusher is provided on the push plate corresponding to the square groove. The yarn pusher extends from the outer wall of the push plate through the square hole to the outer wall of the broken yarn ring until it is flush with the outer wall of the broken yarn ring. Several sliding holes are provided on the fixed plate in the circumferential direction, and sliding rods are provided in the sliding holes. The front ends of the sliding rods are connected to the push plate, and the rear ends are provided with a rear cone sleeve. The cylinder of the impeller mechanism drives the rear cone sleeve to move, which in turn drives the sliding rods to move, thereby driving the push plate to move.

[0008] By adopting the above technical solution, a pusher plate, a yarn pusher seat, a slide bar, and a rear cone sleeve are set up. Before the electric cylinder drives the cutting knife to cut the yarn, the cylinder of the impeller mechanism drives the rear cone sleeve to move outward, which in turn drives the slide bar, the pusher plate, and the yarn pusher seat to move outward. This pushes the yarn wrapped inside the broken yarn ring and the winding yarn ring outward, making it easier for the cutting knife to cut all the yarn on the broken yarn ring and the winding yarn ring.

[0009] Furthermore, the pusher includes a left pusher and a right pusher, which are spaced apart.

[0010] By adopting the above technical solution and setting up left and right push plates, the collision between the cutting blade and the push plates is avoided when the cutting blade cuts the yarn on the winding ring.

[0011] Furthermore, a fixing ring is provided on the rear side of the fixing plate, and the fixing ring has a clearance hole corresponding to the sliding rod. The fixing ring has several through holes spaced circumferentially through it. A circular hole with the same core as the through hole is provided on the side of the fixing ring adjacent to the fixing plate. The diameter of the circular hole is larger than the diameter of the through hole and the depth of the hole is smaller than the depth of the through hole. A fixing block is provided in the circular hole. A spring guide post with a diameter smaller than the through hole is provided on the fixing block. The rear conical sleeve has a mounting hole with the same diameter as the through hole corresponding to the through hole. A compression spring is sleeved on the spring guide post. One end of the compression spring abuts against the fixing block and the other end abuts against the bottom of the mounting hole.

[0012] By adopting the above technical solution, a fixing ring, through hole, round hole, fixing block, spring guide post, and compression spring are set. When the cylinder of the impeller mechanism drives the conical sleeve to move outward, it drives the slide rod, push plate, and yarn pusher to move outward. The compression spring is compressed. When the push plate pushes the yarn outward, the cylinder of the impeller mechanism stops working, the compression spring loses its restraint and releases its elastic force, and resets the push plate and yarn pusher.

[0013] Furthermore, the retaining ring is fitted with a dustproof ring.

[0014] By adopting the above technical solution, a dustproof ring is provided on the outer sleeve of the fixed ring to prevent dust and impurities from entering between the fixed ring and the rear cone sleeve, blocking the sliding hole or mounting hole, and affecting the normal movement of the rear cone sleeve, sliding rod, and push plate.

[0015] Furthermore, an annular groove is formed on the outer wall of the coiled wire ring near the broken wire ring.

[0016] By adopting the above technical solution, an annular groove is opened on the outer wall of the winding ring near the broken yarn ring. The traction and positioning mechanism introduces the yarn into the annular groove, making it easier for the yarn to contact the broken yarn ring and facilitating the process of the broken yarn ring breaking the yarn during the loading process.

[0017] Furthermore, an annular guide groove is provided on the outside of the broken wire ring.

[0018] By adopting the above technical solution, an annular guide groove is set on the outside of the broken yarn ring to guide the yarn position, thereby increasing the success rate of yarn grabbing.

[0019] In summary, this utility model has the following beneficial effects: In this application, a fixed disc, a winding ring, a broken wire ring, a square notch, a mounting frame, an electric cylinder, and a cutting blade are provided. When the glass fiber drawing machine is drawing fibers, the glass fiber yarn falls from the spool plate and moves along the winding ring to the square notch under the action of the traction positioning mechanism. The rotating winding wheel drives the annular fixed disc and the broken wire ring to rotate, and the square groove winds the yarn onto the winding ring, resulting in a high yarn-grabbing success rate. When the drawing machine completes the drawing process and needs to clean the yarn wound on the winding ring, the impeller mechanism rotates, driving the winding ring to rotate and adjusting the two square notches to the length direction of the electric cylinder piston rod. Then, the electric cylinder pushes the blade holder and the cutting blade towards the winding ring until they reach the square notch. The electric cylinder then drives the cutting blade to reciprocate at the square notch, causing the yarn wound on the winding ring to be cut and detached from the winding ring. This process does not require manual intervention, greatly reducing the labor intensity of workers and improving production efficiency. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] like Figure 1-8 As shown in the embodiment of this application, an automatic doffing glass fiber drawing machine is disclosed, including a frame. The frame is equipped with a base plate, a wire-blocking mechanism, a traction and positioning mechanism, a flipping mechanism, a main shaft mechanism, an impeller mechanism, a fixed disk 10, a winding ring 20, a mounting frame 40, and an electric cylinder 41. Specifically, the fixed disk 10 is located at the outer end of the impeller mechanism, and rotates synchronously with the impeller mechanism. The winding ring 20 is located on the outer surface of the fixed disk 10. When the glass fiber drawing machine is loading the yarn, the glass fiber yarn falls from the spool plate and is wound onto the winding ring 20 under the action of the traction and positioning mechanism. An annular baffle 21 is provided on the outer side of the winding ring 20 to ensure that the yarn is wound onto the winding ring 20 and will not slip out from the outside of the winding ring 20. A wire-breaking ring 30 is provided on the outer edge of the fixed disk 10 to complete the process of breaking the yarn during loading. The yarn breakage ring 30 has several square grooves 31 spaced circumferentially. The height of the ring wall of the yarn breakage ring 30 between adjacent square grooves 31 gradually increases along the rotation direction of the winding wheel of the drawing machine, making it easier for the yarn breakage ring 30 to break the yarn. An annular guide groove 32 is provided on the outside of the yarn breakage ring 30 to guide the yarn position and increase the success rate of yarn picking. An annular groove 33 is opened on the outer wall of the winding ring 20 near the yarn breakage ring 30. The traction and positioning mechanism guides the yarn into the annular groove 33, making it easier for the yarn to contact the yarn breakage ring 30 and improving the efficiency of breaking the yarn.

[0031] A square notch 22 is symmetrically provided on the annular baffle 21. The square notch 22 passes through the coiled wire ring 20 and reaches the fixed plate 10, so that both the annular baffle 21 and the coiled wire ring 20 are divided into two halves. A push plate 50 is provided at the outer end of the fixed plate 10. Several sliding holes 11 are provided circumferentially on the fixed plate 10. Sliding rods 12 are provided in the sliding holes 11. The front ends of the sliding rods 12 are connected to the push plate 50, and the rear ends are provided with a rear cone sleeve 13. The cylinder of the impeller mechanism drives the rear cone sleeve 13 to move, which in turn drives the sliding rods 12 to move, thereby driving the push plate 50 to move. The winding ring 20 has a square hole 23 corresponding to the square groove 31. The pusher plate 50 is provided with a yarn pusher seat 51 corresponding to the square groove 31. The yarn pusher seat 51 extends from the outer wall of the pusher plate 50 through the square hole 23 to the outer wall of the broken yarn ring 30 until it is flush with the outer wall of the broken yarn ring 30. The movement of the pusher plate 50 drives the yarn pusher seat 51 to move, pushing the yarn wound on the inner side of the broken yarn ring 30 and the winding ring 20 outward.

[0032] During installation, a fixing ring 60 is provided on the rear side of the fixing plate 10. The fixing ring 60 has a clearance hole corresponding to the sliding rod 12 to avoid interference with the sliding of the sliding rod 12 within the sliding hole 11. The fixing ring 60 has several through holes 61 spaced circumferentially through it. A circular hole 62, coaxially arranged with the through holes 61, is provided on the side of the fixing ring 60 adjacent to the fixing plate 10. The diameter of the circular hole 62 is larger than the diameter of the through hole 61, and its depth is smaller than the depth of the through hole 61. A fixing block 63 is provided within the circular hole 62, and a spring guide post 64 with a diameter smaller than that of the through hole 61 is provided on the fixing block 63. The rear tapered sleeve 13 has a mounting hole 14 with a diameter matching that of the through hole 61 corresponding to the through hole 61. A compression spring 65 is fitted onto the spring guide post 64. One end of the compression spring 65 abuts against the fixed block 63, and the other end abuts against the bottom of the mounting hole 14. When the cylinder of the impeller mechanism drives the rear cone sleeve 13 to move outward, causing the slide rod 12, push plate 50, and yarn pusher 51 to move outward, the compression spring 65 is compressed. After the push plate 50 pushes the yarn outward, the cylinder of the impeller mechanism stops working, the compression spring 65 loses its restraint and releases its elastic force, resetting the push plate 50 and yarn pusher 51. A dustproof ring 66 is fitted over the fixed ring 60 to prevent dust and impurities from entering between the fixed ring 60 and the rear cone sleeve 13, blocking the slide hole 11 or the mounting hole 14, and affecting the normal movement of the rear cone sleeve 13, slide rod 12, and push plate 50.

[0033] In the specific setup, the mounting frame 40 is placed on the base plate, and the electric cylinder 41 is placed at the front end of the mounting frame 40. The piston rod end of the electric cylinder 41 faces the center of the winding ring 20 and is equipped with a knife holder 42. The knife holder 42 is equipped with a cutting blade 43, which is located along the length of the piston rod of the electric cylinder 41. When the drawing machine completes the drawing work and needs to clean the yarn wound on the winding ring 20, the impeller mechanism rotates, driving the winding ring 20 to rotate and adjusting the two square notches 22 to the length of the piston rod of the electric cylinder 41. Then, the electric cylinder 41 pushes the knife holder 42 and the cutting blade 43 toward the winding ring 20 until they reach the square notches 22. The electric cylinder 41 then drives the cutting blade 43 to reciprocate at the square notches 22, so that the yarn wound on the winding ring 20 is cut and detached from the winding ring 20. This process does not require manual intervention, greatly reducing the labor intensity of workers and improving production efficiency. The pusher plate 50 pushes the yarn wrapped inside the broken yarn ring 30 and the winding yarn ring 20 outward, making it easier for the cutting blade 43 to cut all the yarn on the broken yarn ring 30 and the winding yarn ring 20. The pusher plate 50 includes a left pusher plate 52 and a right pusher plate 53, which are spaced apart. The length direction of the gap between the left pusher plate 52 and the right pusher plate 53 is consistent with the direction of the line connecting the two square notches 22, so as to avoid the cutting blade 43 colliding with the pusher plate 50 when cutting the yarn on the winding yarn ring 20.

[0034] The operating principle of the automatic doffing glass fiber drawing machine in this embodiment is as follows: When the glass fiber drawing machine is drawing and loading the fiber, the glass fiber yarn falls from the spool plate and moves along the winding ring 20 to the square notch 22 under the action of the traction positioning mechanism. The rotation of the winding wheel drives the annular fixed plate 10 and the broken wire ring 30 to rotate, and the yarn is wound onto the winding ring 20 under the action of the square groove 31, resulting in a high yarn grabbing success rate. When the drawing machine completes the drawing work and needs to clean the yarn wound on the winding ring 20, the impeller mechanism rotates and drives the winding ring 20 to rotate, adjusting the two square notches 22 to the position of the piston of the electric cylinder 41. Along the length of the rod, the cylinder that starts the impeller mechanism drives the conical sleeve 13 to move outward, which in turn drives the slide rod 12, push plate 50, and yarn pusher 51 to move outward, thereby pushing the yarn wrapped inside the broken yarn ring 30 and the winding ring 20 outward. Then, the electric cylinder 41 drives the knife holder 42 and the cutting knife 43 to move towards the winding ring 20 until they reach the square notch 22. The electric cylinder 41 then drives the cutting knife 43 to reciprocate at the square notch 22, so that the yarn wrapped on the winding ring 20 is cut and detached from the winding ring 20. This process does not require manual intervention, which greatly reduces the labor intensity of workers and improves production efficiency.

[0035] 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.
