Description

Technical Field

[0001] This invention relates to a device for feeding quartz rods into molten rods using a synchronous clamping mechanism. 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] To improve the efficiency of quartz rod melting and drawing, hundreds of quartz rods are typically melted and drawn at a time. Existing clamping structures require clamping each rod individually, which is labor-intensive, tedious, time-consuming, and inefficient. In addition, since flux and stabilizer need to be coated on the quartz rods before melting, the traditional method of pre-coating is not only tedious and time-consuming, but also gradually runs off the quartz rods because the coating is not used immediately, affecting the melting effect. Summary of the Invention

[0004] Based on this, in order to solve the above problems, the present invention provides a quartz rod feeding device that can simultaneously clamp hundreds of quartz rods, and can add flux and stabilizer to the quartz rods just before melting.

[0005] The technical solution of the present invention is as follows: A quartz rod feeding device capable of synchronously clamping rods includes:

[0006] The bar feeding mechanism includes a telescopic cylinder, inside which is fitted a circular piston that slides up and down driven by a hydraulic system, and a piston rod is connected to the circular piston.

[0007] The rod placement plate is coaxially arranged with the telescopic cylinder and connected to the lower part of the piston rod. Multiple rod placement holes are evenly distributed in two concentric circles on the rod placement plate, and the axis of the rod placement holes is parallel to the axis of the telescopic cylinder.

[0008] The clamping mechanism includes an outer fixing ring and an inner fixing ring. The outer fixing ring is located outside the rod placement hole of the outer ring, and the inner fixing ring is fitted inside the rod placement hole of the inner ring. Multiple movable clamps are provided between the inner and outer fixing rings. The multiple movable clamps are spliced ​​into a ring-shaped structure to press the quartz rod placed in the rod placement holes of the inner and outer rings onto the corresponding inner and outer fixing rings. The movable clamps include an outer arc plate, an inner arc plate, and multiple compression springs connected between the inner and outer arc plates.

[0009] The molten rod burner includes a circular tubular combustion tube body located below the rod placement plate. The combustion tube body is coaxially arranged with the rod placement plate. Flame nozzles are arranged radially on the inner and outer annular surfaces of the combustion tube body, corresponding to each quartz rod. The heating area of ​​each flame nozzle covers the passage path of the corresponding quartz rod to heat and melt the corresponding quartz rod passing through.

[0010] The rod-setting mechanism includes a rod-setting ring plate and a drive motor for driving the rod-setting ring plate to rotate. The rod-setting 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 located above the molten rod burner and has lower through holes that correspond one-to-one with the rod placement holes. The ring sleeve is mounted on the output shaft of the drive motor. When the rod-setting ring plate is driven to rotate 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 holes.

[0011] The upper part of the bar ring plate is provided with an annular storage tank for storing flux and stabilizer, and the upper or middle part of the bar ring plate is provided with a liquid flow channel connecting the annular storage tank and each lower through hole.

[0012] The beneficial effects of this solution are as follows: Compared with the prior art, the quartz rod feeding device with synchronous clamping of the rods in this application is used by first removing the movable clamp, rotating the rod ring plate to the first position, inserting all the quartz rods into the corresponding rod placement holes on the rod placement plate, allowing them to fall freely and land on the upper surface of the rod ring plate, and then directly placing the movable clamp on it to squeeze the two rings of quartz rods onto the corresponding outer and inner fixed rings at one time, achieving one-time clamping of all the quartz rods. Then, the drive motor is started to move the rod ring plate to the second position, and then the rod feeding mechanism is started to drive the rod placement plate and all the quartz rods to move down synchronously. Each quartz rod passes through the corresponding upper and lower through holes on the rod ring plate in sequence, and the viscous flux and stabilizer flowing in the annular storage tank can adhere to the surface of the quartz rod. Then, the quartz rod passes through the corresponding flame nozzle on the molten rod burner. Under the action of the flame and with the assistance of the flux and stabilizer, the quartz rod melts according to the set parameters and can be drawn into wire.

[0013] Therefore, the quartz rod feeding device with synchronous clamping of the present application can achieve synchronous clamping of hundreds of quartz rods at one time, with low manual labor intensity and high work efficiency. Moreover, the quartz rods do not require additional manpower to apply flux and stabilizer. The flux and stabilizer are applied just before the quartz rod melts, avoiding the loss of flux and stabilizer and significantly improving the overall work efficiency.

[0014] Based on the above scheme, a further improvement is made as follows: at least one storage cup for storing flux and stabilizer is installed on the upper part of the bar ring plate, and the lower opening of the storage cup communicates with the annular storage tank. The storage cup allows for the storage of more flux and stabilizer, thereby reducing the frequency of flux and stabilizer replenishment, and also facilitates the control of flux and stabilizer flow rate.

[0015] Based on the above scheme, further improvements are made as follows: a switch valve is installed at the lower opening of the storage cup, and even further, a solenoid valve can be used. The solenoid valve can be conveniently electrically controlled to realize the flow of flux and stabilizer during the rod feeding process, and to stop the injection of flux and stabilizer into the annular storage tank during the rod loading process, thereby reducing the loss of flux and stabilizer.

[0016] 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. Since 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.

[0017] 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.

[0018] Based on the above scheme, further improvements are made as follows: Annular grooves are provided on the lower surface of the annular plate and / or the upper surface of the molten rod burner. The rod-supporting mechanism includes multiple support balls, which are rotatably disposed between the molten rod burner and the annular plate. The design of the support balls and the annular grooves not only provides movable support for the annular plate, improving its levelness 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.

[0019] 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. Attached Figure Description

Detailed Implementation

[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.

[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] Specific embodiments of the quartz rod feeding device of the present invention with synchronous clamping rods are as follows: Figure 1 As shown, it includes a rod feeding mechanism, a rod placement tray 3, a rod clamping mechanism 4, a molten rod burner 6, and a rod alignment mechanism 100.

[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] The rod-setting mechanism 100 is installed above the molten rod burner, and the rod-setting fixture can move freely. The rod-setting mechanism 100 includes a rod-setting ring plate 110 and a drive motor 120 for rotating the rod-setting ring plate 110. The rod-setting ring plate 110 includes a concentrically arranged annular plate 111 and a ring sleeve, and connecting strips 113 radially connected between the ring sleeve and the annular plate 111. The annular plate 111 is positioned above the molten rod burner 6, and has two rings of evenly distributed lower through holes 114 for each quartz rod 7 to pass through. The lower through holes 114 are used for connecting with… The rod placement holes 32 for placing quartz rods 7 on the rod placement tray 3 are arranged one-to-one. The ring sleeve is installed on the output shaft of the drive motor 120. When the drive motor 120 drives the rod ring plate 110 to rotate, it has two positions: a first position where the lower end of the quartz rod 7 contacts the upper surface of the annular plate 111, and a second position where the quartz rod 7 passes through the lower through hole 114. The axis of the output shaft of the drive motor 120, the ring sleeve, and the rod ring plate 110 is coaxial with the axis of the molten rod burner. A flexible buffer layer 115 is provided on the upper surface of the annular plate 111 in the area between any two adjacent lower through holes 114 to buffer the quartz rods 7. With the above structure of this application, hundreds of quartz rods 7 can fall into place simultaneously by their own weight. The flexible buffer layer 115 is essential to effectively prevent damage to the quartz rods 7 from strong impacts. The flexible buffer layer 115 is a rubber strip embedded in the upper surface of the annular plate 111. This design allows for easy replacement of the flexible buffer layer 115 after it wears out.

[0042] The upper part of the bar ring plate 110 is provided with an annular storage tank 117 for storing flux and stabilizer. The cross-section of the annular storage tank 117 is rectangular. The upper or middle part of the bar ring plate 110 is provided with a liquid flow channel 118 connecting the annular storage tank 117 and each lower through hole 114. In this embodiment, the liquid flow channel 118 is a circular channel provided in the bar ring plate 110.

[0043] At least one storage cup for storing flux and stabilizer is installed on the upper part of the bar ring plate 110. The lower opening of the storage cup communicates with the annular storage tank 117. In this embodiment, three storage cups are provided, evenly distributed around the circumference of the bar ring plate 110. The storage cups can store more flux and stabilizer, thereby reducing the frequency of flux and stabilizer replenishment, and also facilitating the control of flux and stabilizer flow rate. A switch valve is provided at the lower opening of the storage cup, or more specifically, a solenoid valve. The solenoid valve allows for convenient electrical control, enabling the flux and stabilizer to flow downwards during the bar loading process and stopping the injection of flux and stabilizer into the annular storage tank 117 during the bar loading process, thereby reducing the loss of flux and stabilizer.

[0044] An annular groove 116 is provided on the lower surface of the annular plate 111 and / or the upper surface of the molten rod burner 6. The rod-supporting mechanism 100 includes multiple support balls 130, which are rotatably disposed between the molten rod burner 6 and the annular plate 111. The design of the support balls 130 and the annular groove 116 not only provides movable support for the annular plate 111, improving the levelness of the annular plate 111 during rotation and preventing skewness that could lead to hole misalignment, but also reduces the burden on the drive motor 120 and extends its service life. There are four connecting bars 113, which are evenly distributed along the circumference of the ring.

[0045] Compared to existing technologies, the quartz rod feeding device with synchronous clamping of the present application, when in use, first removes the movable clamp, rotates the rod ring plate 110 to the first position, inserts all the quartz rods into the corresponding rod placement holes on the rod placement tray, allows them to fall freely onto the upper surface of the rod ring plate 110, and then directly places the movable clamp on it, thereby pressing the two rings of quartz rods onto the corresponding outer and inner fixing rings at one time, achieving one-time clamping of all quartz rods, and then starts the drive motor 120. The bar ring plate 110 is moved to the second station. Then the bar feeding mechanism is started to drive the bar placement plate and all the quartz bars to move down synchronously. Each quartz bar passes through the corresponding lower through hole 114 on the bar ring plate 110 in sequence. The viscous flux and stabilizer flowing in the annular storage tank 117 can adhere to the surface of the quartz bar. Then, the quartz bar passes through the corresponding flame nozzle 62 on the melting bar burner 6. Under the action of the flame and with the assistance of the flux and stabilizer, the quartz bar melts according to the set parameters and can be drawn into wire.

[0046] Therefore, the quartz rod feeding device with synchronous clamping of the present application can achieve synchronous clamping of hundreds of quartz rods at one time, with low manual labor intensity and high work efficiency. Moreover, the quartz rods do not require additional manpower to apply flux and stabilizer. The flux and stabilizer are applied just before the quartz rod melts, avoiding the loss of flux and stabilizer and significantly improving the overall work efficiency.
