Description

Technical Field

[0001] This invention relates to a tooling assembly for feeding quartz rods into molten rods. Background Technology

[0002] Quartz fiber is a fiber made from high-purity silica and natural quartz crystals. It possesses heat resistance, corrosion resistance, and flexibility. It exhibits high strength retention at high temperatures, dimensional stability, thermal shock resistance, chemical stability, light transmittance, and good electrical insulation. Quartz fiber production requires the use of quartz rods; the rods are melted, fed, and drawn simultaneously. The equipment used is called a quartz rod feeding device.

[0003] Existing quartz rod feeding mechanisms generally use motor-driven ball screw mechanisms. High-precision ball screw mechanisms are typically imported, resulting in high costs and extremely high installation accuracy requirements. Ordinary precision ball screw mechanisms are less accurate, requiring longer ball screws for longer quartz rods. The longer the ball screw, the worse its straightness, causing the quartz rod to deviate from the set temperature range of the flame nozzle, affecting melting quality and ultimately product quality. Furthermore, ball screw mechanisms are not impact-resistant and are easily damaged by reverse forces, generating considerable noise during operation and causing inconvenience. Additionally, ball screw mechanisms have limited load-bearing capacity; traditional ball screw mechanisms reach their limit driving 100 quartz rods. To improve production efficiency, 200 to 400 quartz rods need to be processed at a time. To reduce the burden of loading, longer, larger diameter quartz rods are desired as raw materials, but existing ball screw mechanisms cannot meet this demand. Moreover, the current layout of the loading tray and burner cannot accommodate the processing of larger quantities of quartz rods.

[0004] To address these issues, the applicant has designed a device that utilizes a hydraulically driven quartz rod clamping plate, enabling the clamping and feeding of a larger number of quartz rods at once. However, this device requires removing hundreds of quartz rods from the quartz rod container and placing them one by one into the corresponding positions on the quartz rod clamping plate before clamping them. This process necessitates frequent bending and moving up and down, as well as frequent temporary fixing of the quartz rods, making the loading process extremely slow and laborious. More importantly, the molten rod feeding device must be stopped before loading rods can begin, while the operator is idle and unable to load rods during the operation of the molten rod feeding device, resulting in extremely low work efficiency. Summary of the Invention

[0005] In view of this, in order to solve the above problems, the present invention provides a quartz rod feeding device for a quartz rod feeding fixture assembly. Quartz rods are loaded into the feeding fixture outside the equipment and placed on the equipment at once for use. Moreover, when the equipment is in operation, the operator can simultaneously load rods into other feeding fixtures, so that the downtime for changing rods is very short and the efficiency of molten rod drawing is significantly improved.

[0006] The technical solution of the present invention is as follows: A tooling assembly for feeding a quartz rod to a melting rod includes:

[0007] The rod-aligning mechanism includes a rod-aligning ring plate and a drive motor for rotating the rod-aligning ring plate. The rod-aligning ring plate includes a concentrically arranged annular plate and a ring sleeve, and connecting strips radially connected between the ring sleeve and the annular plate. The annular plate is used to be positioned above the molten rod burner. The annular plate has two rings and multiple evenly distributed lower through holes for each quartz rod to pass through. The lower through holes are configured to correspond one-to-one with the rod placement holes on the rod placement tray for placing quartz rods. The ring sleeve is mounted on the output shaft of the drive motor. When the rod-aligning ring plate is rotated by the drive motor, it has: a first position where the lower end of the quartz rod contacts the upper surface of the annular plate, and a second position where the quartz rod passes through the corresponding lower through hole.

[0008] The rod loading fixture has at least two parts, including a rod loading ring plate and an annular baffle plate stacked one on top of the other. The rod loading ring plate has two rings of evenly distributed upper through holes for each quartz rod to pass through. The upper through holes are set one-to-one with the rod placement holes on the rod placement tray. The rod loading ring plate is formed by two rod loading half-ring plates that are hinged at one end and detachably connected at the other end. The annular baffle plate is formed by two semi-annular baffle plates that are hinged at one end and detachably connected at the other end. The rod loading ring plate and the annular baffle plate are hinged by the same hinge axis. The lower part of the hinge axis is provided with a long positioning pin for insertion and engagement with the positioning hole on the rod placement tray. The rod loading ring plate is symmetrically provided with short positioning pins about the center of the hinge axis for insertion and engagement with the positioning hole on the rod placement tray. Both rod loading half-ring plates and two semi-annular baffle plates can rotate independently around the hinge axis.

[0009] The beneficial effects of this solution are as follows: Compared with the prior art, when the rod loading fixture assembly of this application is used in conjunction with the quartz rod feeding and melting device, at least two rod loading fixtures can be used alternately. Operators can easily load hundreds of quartz rods one by one into the upper through-hole of the loading ring plate while seated. The initial annular baffle, stacked below the loading ring plate, supports the lower end of the quartz rods, essentially forming a tray. After placing the quartz rods for one loading fixture, the fixture is lifted manually or using hoisting equipment, ensuring it is as horizontal as possible. When it reaches the vicinity of the quartz rod feeding and melting device, the fixture is rotated open around the hinge shaft, forming an open... The opening is designed to be easily fitted from the side of the device, over the telescopic cylinder of the device, without having to be fitted from top to bottom. After fitting, the rod-loading fixture is combined, and then the long positioning pin is first inserted into the corresponding positioning hole of the device to initially determine the reference position. Then, the short positioning pin is inserted into the positioning hole at the symmetrical position on the other side. Then, the two parts of the lower annular baffle are rotated open with the hinge shaft as the pivot, and the quartz rod can automatically fall down by gravity and finally land on the upper surface of the rod ring plate. At this time, the upper end of the quartz rod is fixed by the rod clamping mechanism. The drive motor is started to rotate the rod ring plate from the first station to the second station, and the subsequent melting and drawing of the rod can be carried out.

[0010] As can be seen from the above working process, firstly, during the wire drawing process of the molten rod, the operator can use the rod loading fixture to pre-load the rods, allowing the working time to overlap and reducing equipment downtime, thereby improving production efficiency; secondly, compared with the traditional method of manually loading the rods one by one onto the rod placement tray, this application can quickly insert the quartz rods into the rod loading fixture in a more relaxed and faster way, which not only reduces the labor intensity but also further improves the work efficiency; thirdly, after adopting the rod loading fixture component of this application, the operation difficulty of the rod clamping mechanism is reduced, and all quartz rods can be clamped at once, which is also convenient for operation, reduces labor intensity, and improves work efficiency; in addition, the setting of long and short positioning pins allows for initial positioning with the long pins, which does not affect the rotation of the fixture around the hinge axis, and then the short pins are used for final positioning, which is accurate and convenient.

[0011] Based on the above solution, a further improvement is made as follows: a flexible buffer layer is provided on the upper surface of the annular plate in the area between any two adjacent lower through holes to cushion the quartz rods. With the above structure of this application, hundreds of quartz rods can fall into place simultaneously under their own weight. The flexible buffer layer is essential and can effectively prevent damage from strong impacts to longer and heavier quartz rods.

[0012] Based on the above solution, a further improvement is made as follows: the flexible buffer layer is a rubber strip embedded in the upper surface of the annular plate. This design allows for easy replacement of the flexible buffer layer after it wears down.

[0013] Based on the above solution, further improvements are made as follows: the lower surface of the annular plate is provided with an annular groove, and the rod-supporting mechanism includes multiple support balls, which are rolled between the molten rod burner and the annular groove. The design of the support balls and the annular groove not only provides movable support for the annular plate, improving its horizontality during rotation and preventing skewing that could lead to hole misalignment, but also reduces the burden on the drive motor and extends its service life.

[0014] Based on the above solution, further improvements are made as follows: a mounting plate is hinged to one end of the rod-mounting semi-ring plate away from the hinge axis, and a locking pin is vertically installed at the lower part of the mounting plate. A locking hole is provided on the other end of the rod-mounting semi-ring plate away from the hinge axis for the locking pin to be inserted, thereby achieving a detachable connection between the two rod-mounting semi-ring plates. The mounting plate allows for convenient and stable connection and separation of the free ends of the two rod-mounting semi-ring plates.

[0015] Based on the above scheme, further improvements are made as follows: permanent magnets are respectively provided at the ends of the two rod-mounted semi-annular plates and / or the two semi-annular baffles away from the hinge axis to achieve mutual attraction. Using powerful permanent magnets to achieve mutual attraction is more convenient and faster.

[0016] Based on the above solution, further improvements are made as follows: the material of the bar ring plate and / or the bar loading ring plate and / or the annular baffle is a lightweight alloy. Using a lightweight alloy ensures easier handling of the bar loading fixture and reduces the load on the drive motor when rotating the bar ring plate. Furthermore, the high strength and hardness of alloy steel ensures the accuracy of the bar loading process.

[0017] Based on the above scheme, the following improvements are made: there are at least three connecting strips, which are evenly distributed along the circumference of the ring.

[0018] Based on the above solution, a further improvement is made as follows: a coating is provided on the wall of the upper through hole to increase the friction between the quartz rod and the hole, allowing the quartz rod to descend slowly. This design can prevent the quartz rod from falling too quickly, especially for longer and heavier quartz rods, effectively reducing the impact damage rate. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0033] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0034] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0035] Since the upper bar tooling assembly is used in conjunction with the quartz rod feeding and melting device, the quartz rod feeding and melting device will be introduced first before describing the upper bar tooling assembly in detail. Figure 1 As shown, the quartz rod 7 molten rod feeding device includes a rod feeding mechanism, a hydraulic control system, a rod placement plate 3, a rod clamping mechanism 4, and a molten rod burner 6.

[0036] The rod feeding mechanism includes a telescopic cylinder 2, which includes an annular sliding cavity 21. The top and bottom of the sliding cavity 21 are respectively provided with oil holes 22 connecting the inside and outside. An annular piston 23 is slidably mounted inside the sliding cavity 21. Multiple piston rods 24 are connected to the bottom surface of the annular piston 23, and each piston rod 24 extends out from the bottom of the sliding cavity 21. The piston rods 24 are slidably and sealingly fitted with the bottom of the sliding cavity 21. A guide hole 26 with a lower opening is provided at the axis of the telescopic cylinder 2. A through hole is provided at the bottom of the sliding cavity 21 corresponding to each piston rod 24, and a step seal is installed at the through hole, with the piston rod 24 passing through the step seal. The annular piston 23 includes a large-diameter section located in the middle and small-diameter sections symmetrically arranged on both sides of the large-diameter section. Sealing rings of corresponding sizes are respectively provided on the inner and outer circumferential surfaces of the large-diameter section. Annular mounting grooves are provided on both the inner and outer circumferential surfaces of the large-diameter section for installing the sealing rings. The edge of the annular mounting groove is guided and slidably fitted with the inner wall surface of the sliding cavity 21. The small diameter section allows hydraulic oil to drive the annular piston 23 to move even when it is in contact with the top and bottom of the sliding cavity 21, thus preventing the annular piston 23 from getting stuck. The sealing ring prevents hydraulic oil from flowing between the two sides of the annular piston 23. The annular mounting groove allows the sealing ring to be embedded within it, preventing misalignment during sliding. The design of the groove edge guiding the sliding fit between the annular mounting groove and the inner wall of the sliding cavity 21 further improves the guiding performance between the annular piston 23 and the inner wall of the sliding cavity 21, thus improving guiding accuracy.

[0037] The hydraulic control system has two hydraulic oil pipes that can alternately supply oil. These two pipes are connected to two oil ports 22 to drive the up-and-down movement of the annular piston 23. Specifically, the hydraulic oil tank stores hydraulic oil; the oil pump draws and pumps the hydraulic oil, and can be a hydraulic pump or a piston pump, etc. An electric motor drives the oil pump, such as a geared motor. The two-position four-way solenoid directional valve has a valve body and a directional valve core. The valve body has two internal oil ports and two external oil ports. The two internal oil ports are connected to the oil pump outlet and the hydraulic oil tank, respectively. The two external oil ports are connected to the hydraulic oil pipes. The directional valve core has a first valve position that connects the oil pump to the first external oil port and the second external oil port to the hydraulic oil tank, and a second valve position that connects the oil pump to the second external oil port and the first external oil port to the oil tank. The controller controls the start and stop of the motor and the switching of the directional valve core's valve position. A relief valve is located between the oil pump outlet and the oil tank, providing safety protection to ensure that the system pressure does not become excessive.

[0038] The rod placement disk 3 is coaxially arranged with the telescopic cylinder 2 and connected to the lower part of the piston rod 24. An upwardly extending guide rod 31 is provided at its upper axis, and the guide rod 31 slides in a guide hole 26. Multiple rod placement holes 32 are concentrically arranged in inner and outer rings on the rod placement disk 3, and the axis of the rod placement holes 32 is parallel to the axis of the telescopic cylinder 2. The rod placement disk 3 is made of carbon fiber composite material or titanium alloy; multiple evenly distributed weight-reduction holes 33 are provided on the rod placement disk 3.

[0039] The clamping mechanism 4 includes an outer fixing ring 41 and an inner fixing ring 42. The outer fixing ring 41 is fitted outside the rod placement hole 32 of the outer ring, and the inner fixing ring 42 is fitted inside the rod placement hole 32 of the inner ring. Multiple movable clamps 43 are provided between the inner and outer fixing rings 41, and these movable clamps 43 are assembled into a circular structure to press the quartz rod 7 placed in the rod placement holes 32 of the inner and outer rings onto the corresponding inner and outer fixing rings 41. The movable clamp 43 includes an outer arc-shaped plate 431, an inner arc-shaped plate 432, and multiple compression springs 433 connecting the inner and outer arc-shaped plates 431. At least one elastic rubber strip extending along the length direction is embedded on the inner arc-shaped surface of the inner arc-shaped plate 432 and / or the outer arc-shaped surface of the outer arc-shaped plate 431. After the inner and outer arc-shaped plates 431 are provided with elastic rubber strips on the side that contacts the quartz rod 7, it can clamp the quartz rod 7 more tightly and prevent the quartz rod 7 from slipping after clamping. On the other hand, it can prevent mutual wear between the hard quartz rod 7 and the hard clamping mechanism 4. At least one elastic rubber ring is embedded on the outer circumferential surface of the inner fixing ring 42 and / or the inner circumferential surface of the outer fixing ring 41. On the one hand, it can clamp the quartz rod 7 more tightly and prevent the quartz rod 7 from slipping after clamping. On the other hand, it can prevent mutual wear between the hard quartz rod 7 and the hard clamping mechanism 4. The clamping mechanism 4 includes a steel ring 44, which is sequentially inserted into the compression springs 433 of each movable clamp 43. The compression springs 433 are arranged radially along the steel ring 44. The steel ring 44 can position each movable clamp 43, prevent the movable clamp 43 from jumping or displacing and affecting the accurate clamping of the quartz rod 7, and also ensure that each movable clamp 43 is assembled into a complete ring. The rod clamping mechanism 4 is mounted on the upper part of the rod placement plate 3. This makes it easier to fix the rod clamping mechanism 4 relative to the rod placement plate 3.

[0040] The fused rod burner 6 includes a circular tubular combustion tube 61, coaxially fixed at the bottom. Flame nozzles 62 are radially arranged on the inner and outer annular surfaces of the combustion tube 61, corresponding one-to-one with each quartz rod 7. The heating area of ​​each flame nozzle 62 covers the path of the corresponding quartz rod 7 to heat and melt it. The cross-section of the inner cavity of the combustion tube 61 is rectangular. At least three mixed gas inlets are evenly distributed at the bottom of the combustion tube 61, with mixed gas being introduced into each inlet simultaneously. Since the fused rod burner 6 of this design can melt more quartz rods 7 and has a relatively large diameter, the even distribution of multiple mixed gas inlets makes the mixed gas distribution within the combustion tube 61 more uniform, thereby ensuring the uniformity of the gas ejected from each flame nozzle 62. The combustion tube 61 is filled with a honeycomb structure made of high-temperature resistant material to further ensure a more uniform distribution of the mixed gas within the combustion tube 61.

[0041] Specific embodiments of the upper rod tooling assembly for the quartz rod 7 feeding and melting rod device of the present invention are as follows: Figure 1 As shown, the quartz rod 7 feeding rod device uses a rod tooling assembly including a rod alignment mechanism and a rod loading tool. The rod alignment mechanism is installed above the rod burner, while the rod loading tool can move freely.

[0042] Specifically, such as Figure 1 , 3As shown in Figure 7, the rod-aligning mechanism includes a rod-aligning ring plate and a drive motor for rotating the rod-aligning ring plate. The rod-aligning ring plate includes a concentrically arranged annular plate and a ring sleeve, and connecting strips radially connected between the ring sleeve and the annular plate. The annular plate is positioned above the molten rod burner 6. The annular plate has two rings and multiple evenly distributed lower through holes for each quartz rod 7 to pass through. The lower through holes correspond one-to-one with the rod placement holes 32 on the rod placement tray 3 for placing the quartz rods 7. The ring sleeve is mounted on the output shaft of the drive motor. When the rod-aligning ring plate is rotated by the drive motor, it has two positions: a first position where the lower end of the quartz rod 7 contacts the upper surface of the annular plate, and a second position where the quartz rod 7 passes through the corresponding lower through holes. The output shaft of the drive motor, the ring sleeve, and the axis of the rod-aligning ring plate are coaxial with the axis of the rod burner. A flexible buffer layer is provided on the upper surface of the annular plate between any two adjacent lower through holes to buffer the quartz rods 7. With the structure described in this application, hundreds of quartz rods 7 can simultaneously fall into place under their own weight. A flexible buffer layer is essential to effectively prevent damage from strong impacts to longer and heavier quartz rods 7. The flexible buffer layer is a rubber strip embedded in the upper surface of the annular plate. This design allows for easy replacement after wear. An annular groove is provided on the lower surface of the annular plate. The rod mechanism includes multiple support balls, which are rolled between the molten rod burner 6 and the annular groove. The design of the support balls and the annular groove not only provides movable support for the annular plate, improving its horizontality during rotation and preventing skewness that could lead to hole misalignment, but also reduces the load on the drive motor and extends its service life. There are four connecting strips, evenly distributed along the circumference of the ring.

[0043] There are at least two rod-loading fixtures, such as... Figure 1 , 2As shown in Figure 4-6, the rod loading fixture includes a rod loading ring plate and an annular baffle plate stacked sequentially. The rod loading ring plate has two rings and multiple evenly distributed upper through holes for each quartz rod 7 to pass through. The upper through holes are configured to correspond one-to-one with the rod placement holes 32 on the rod placement tray 3 for placing the quartz rods 7. The rod loading ring plate is formed by two rod loading half-ring plates that are hinged at one end and detachably connected at the other end. The annular baffle plate is formed by two semi-annular baffle plates that are hinged at one end and detachably connected at the other end. The rod loading ring plate and the annular baffle plate are hinged together by the same hinge axis. The lower part of the hinge axis is provided with a long positioning pin for insertion and engagement with the positioning hole 34 on the rod placement tray 3. The rod loading ring plate is symmetrically provided with short positioning pins about the center of the hinge axis for insertion and engagement with the positioning hole 34 on the rod placement tray 3. Both rod loading half-ring plates and two semi-annular baffle plates can rotate independently around the hinge axis. The wall of the through hole is coated with a coating that increases the friction between the through hole and the quartz rod 7, allowing the quartz rod 7 to descend slowly. This design prevents the quartz rod 7 from falling too quickly, especially for longer and heavier quartz rods, effectively reducing the impact damage rate of the quartz rod 7.

[0044] One of the rod-loading semi-ring plates has a hinge plate at the end furthest from the hinge axis, and a locking pin is vertically installed at the lower part of the hinge plate. The other rod-loading semi-ring plate has a locking hole at the end furthest from the hinge axis for the locking pin to be inserted, thereby realizing the detachable connection of the two rod-loading semi-ring plates. The installation of the hinge plate can conveniently and stably realize the connection and separation of the free ends of the two rod-loading semi-ring plates.

[0045] The bar ring plate and / or the bar loading ring plate and / or the annular baffle are made of lightweight alloy. Using lightweight alloy ensures easier handling of the bar loading fixture and reduces the load on the drive motor when rotating the bar ring plate. Furthermore, the high strength and hardness of alloy steel ensures the accuracy of the bar loading process.

[0046] In other embodiments, permanent magnets are respectively provided at the ends of the two rod-mounted semi-annular plates and / or the two semi-annular baffles away from the hinge axis to achieve mutual attraction. Using powerful permanent magnets to achieve the attraction between the two is more convenient and faster.

[0047] Compared to existing technologies, the rod loading fixture assembly of this application, when used in conjunction with the quartz rod 7 feeding and melting device, allows at least two loading fixtures to load rods in turn. Operators can easily load hundreds of quartz rods 7 one by one into the upper through-hole of the loading ring plate while seated. The initial annular baffle, stacked below the loading ring plate, supports the lower end of the quartz rods 7, effectively forming a tray. After placing the quartz rods 7 in one loading fixture, the fixture is lifted manually or using hoisting equipment, ensuring it is as horizontal as possible. When it reaches the vicinity of the quartz rod 7 feeding and melting device, the loading fixture is rotated open around the hinge shaft, creating an opening for easy access from the loading ring. The device is fitted on the side and placed over the telescopic cylinder 2 of the device, without having to be fitted from top to bottom. After fitting, the rod-loading fixture is combined. Then, the long positioning pin is first inserted into the corresponding positioning hole 34 of the device to initially determine the reference position. Then, the short positioning pin is inserted into the positioning hole 34 at the symmetrical position on the other side. Then, the two parts of the lower annular baffle are rotated open with the hinge shaft as the pivot. The quartz rod 7 can then automatically fall down by gravity and finally land on the upper surface of the rod ring plate. At this time, the upper end of the quartz rod 7 is fixed by the rod clamping mechanism 4. The drive motor is started to rotate the rod ring plate from the first station to the second station for subsequent rod drawing work.

[0048] As can be seen from the above working process, firstly, during the wire drawing process of the molten rod, the operator can use the rod loading fixture to pre-load the rods, allowing the working time to overlap and reducing equipment downtime, thereby improving production efficiency; secondly, compared with the traditional method of manually loading the rods one by one onto the rod placement tray 3, this application can more easily and quickly insert the quartz rods 7 into the rod loading fixture, which not only reduces the workload but also further improves work efficiency; thirdly, after adopting the rod loading fixture assembly of this application, the operational difficulty of the rod clamping mechanism 4 is reduced, and all quartz rods 7 can be clamped at once, which is also convenient for operation, reduces labor intensity, and improves work efficiency; in addition, the setting of long and short positioning pins allows for initial positioning with the long pins, which does not affect the rotation of the fixture around the hinge axis, and then the short pins are used for final positioning, which is accurate and convenient.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
