Description

Technical Field

[0001] This invention relates to the field of glass fiber manufacturing equipment technology, and in particular to a glass fiber production line for automotive headliners and its processing method. Background Technology

[0002] In the glass fiber production process, glass raw materials are usually melted and then conveyed to a drawing screen. The molten glass passes through the holes or nozzles on the drawing screen to form glass filaments, which are then drawn and wound to form glass fibers. The drawing screen is in a high-temperature environment for a long time and is prone to deformation, blockage or wear, requiring disassembly and replacement.

[0003] Chinese Patent Publication No. CN116395953A discloses an easily replaceable glass fiber drawing device and its usage method. The device includes a glass fiber drawing machine body, a melting fixture above the machine body for melting raw materials, a drawing passage below the melting fixture, a mounting frame below the drawing passage, and a spinneret on the mounting frame. The device also includes: a traction mechanism mounted on the glass fiber drawing machine body for lifting and lowering the spinneret; a position changing mechanism mounted on a guide cylinder for changing the position of the spinneret; and a control unit for improving the stability and accuracy of the spinneret during lifting and position changing.

[0004] In the existing technology, the wire drawing plate replacement structure is mainly used to drive the wire drawing plate to descend, change position and rise again. However, after the original wire drawing plate is separated from the melting component, the fixed sealing surface around the outlet of the melting component may be attached with solidified glass, sealing material debris or refractory material particles. When the new wire drawing plate rises directly and is pressed, the above-mentioned residues may cause the wire drawing plate to be locally raised or tilted, and form a state where the sealing surface is not fully fitted after being lifted into place, thus causing local gaps and glass melt leakage.

[0005] Therefore, it is necessary to provide a fiberglass production line for automotive headliners and its processing method to solve the above-mentioned technical problems. Summary of the Invention

[0012] As a further aspect of the present invention: the guide rail includes a lower feeding section, an outer lifting section near the melting assembly, an upper cleaning section, and an inner descending section away from the melting assembly that are interconnected; the push rod extends vertically into the outer lifting section.

[0013] As a further aspect of the present invention: a side plate is slidably provided at the end of the slag receiving tray away from the cleaning component, and a square frame is elastically provided at the center of the side plate. The square frame is located on the side of the side plate close to the cleaning component. Two sets of centrally symmetrical support rods are provided between the bottom plate of the cleaning component and the square frame. Each support rod is fitted with a positioning component, which is located close to the square frame.

[0014] As a further embodiment of the present invention: the positioning component includes an L-shaped seat sleeved on the support rod, a push block slidably disposed on the L-shaped seat, a threaded rod rotatably connected to the push block and threadedly connected to the L-shaped seat, and a horizontal block slidably disposed on the L-shaped seat, wherein the push block and the horizontal block are provided with mutually cooperating inclined surfaces.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: In use, when the mounting frame moves the drawing plate upward, the cleaning component moves into the receiving groove through the cooperation of the traction rope and transmission component, thereby cleaning the bottom fixed sealing surface of the molten material assembly after the drawing plate is replaced. This ensures that the drawing plate and the bottom fixed sealing surface of the molten material assembly are in a highly sealed and fitted state, avoiding problems such as local elevation, tilting, and glass melt leakage caused by residues after the drawing plate is in contact with the molten material assembly. The slag receiving tray can simultaneously receive residual glass melt and scrape off the residue, reducing the risk of residue contaminating the drawing plate and the winding assembly.

[0031] like Figures 1-10 As shown, a glass fiber production line for automotive headliners and its processing method include a main body 1 and a melting assembly 2. The melting assembly 2 is mounted on one side of the main body 1 via a mounting plate. A drawing stencil 4 is provided at the bottom of the melting assembly 2. A mounting frame 3 is provided on the main body 1. The mounting frame 3 is fixedly connected to one side wall of the drawing stencil 4. A winding assembly 6 is provided on one side of the main body 1 and below the melting assembly 2. The winding assembly 6 is used to pull and wind the glass fiber filaments formed by the drawing stencil 4. The resulting glass fiber can be used as a reinforcing material for automotive headliner composite materials.

[0032] The melting component 2, the drawing stencil 4, and the winding component 6 all adopt existing technologies. The melting component 2 is used to melt the glass raw material and transport the molten glass to the drawing stencil 4. The drawing stencil 4 is used to form glass fiber filaments from the molten glass. The winding component 6 is used to pull and wind the formed glass fiber filaments. The specific structure and working principle are not described in detail here. The lower end of the melting component 2 is provided with an outlet for the glass liquid to flow out. The outer periphery of the outlet forms a U-shaped fixed sealing surface that matches the upper sealing frame of the drawing stencil 4. The mounting frame 3 is set below the melting component 2. The drawing stencil 4 is detachably and fixedly installed on the mounting frame 3. The mounting frame 3 is connected to the lifting mechanism on the main body 1 of the equipment, so that the drawing stencil 4 can move between the working position that is pressed and matched with the melting component 2, the descending avoidance position that is separated from the melting component 2, and the position for changing the stencil.

[0033] Reference Figures 1-5 As shown, the main body 1 of the equipment is provided with a horizontally extending receiving groove 22 on one side of the melting component 2. A slag receiving plate 5 is slidably arranged in the receiving groove 22, and a cleaning component 10 is provided on the slag receiving plate 5. The side wall of the main body 1 is provided with a vertically extending sliding groove 7, and a trigger plate 8 is slidably arranged in the sliding groove 7. When the mounting frame 3 descends, it can press against the trigger plate 8. A traction rope 9 and a transmission component are provided between the trigger plate 8 and the slag receiving plate 5, so that the slag receiving plate 5 and the cleaning component 10 can reciprocate between the receiving position in the receiving groove 22 and the extended position below the fixed sealing surface.

[0034] When the mounting frame 3 moves the wire drawing plate 4 downward, the mounting frame 3 cooperates with the trigger plate 8 to move the cleaning component 10 towards the bottom of the melting component 2 through the traction rope 9 and the transmission component. When the mounting frame 3 moves the wire drawing plate 4 upward, the cleaning component 10 moves into the receiving groove 22 through the traction rope 9 and the transmission component, and completes the cleaning of the bottom fixed sealing surface of the melting component 2.

[0035] Reference Figure 3 and Figure 4 As shown, the cleaning component 10 includes a base plate and a cleaning strip disposed on the top of the base plate. Both ends of the base plate are elastically connected to slides via elastic members. The slag receiving tray 5 has grooves on both sides that cooperate with the slides, so that the cleaning component 10 can float vertically relative to the slag receiving tray 5 and move horizontally along the slag receiving tray 5. The transmission component and the end of the slag receiving tray 5 away from the cleaning component 10 are fixedly connected by bolts. The cleaning strip crosses the outer contour of the U-shaped fixed sealing surface laterally. The slag receiving area of ​​the slag receiving tray 5 covers the discharge port and the area below the fixed sealing surface in the planar projection, so as to receive a small amount of residual glass liquid as well as solidified glass, sealing material debris and refractory particles scraped off during the cleaning process, reducing the situation where residue falls onto the wire drawing plate 4 or the winding assembly 6.

[0036] When replacing the wire-drawing strainer 4, the mounting frame 3 supporting the original wire-drawing strainer 4 is first driven to descend, separating the original wire-drawing strainer 4 from the fixed sealing surface and creating a clearance gap for the cleaning component 10 to enter. The mounting frame 3 continues to descend and presses against the trigger plate 8. The trigger plate 8, through the traction rope 9 and the transmission assembly, drives the slag receiving tray 5 and the cleaning component 10 to extend to a low position below the fixed sealing surface. Subsequently, the original working wire-drawing strainer 4 and the new wire-drawing strainer 4 are replaced. The mounting frame 3 supporting the new wire-drawing strainer 4 begins to move upward and reset. During this process, the transmission assembly causes the cleaning component 10 to return to the receiving trough 22. As the cleaning component 10 moves into the receiving trough 22, it sequentially scrapes the two long sides and two short sides of the U-shaped fixed sealing surface, removing the residue adhering to the surface. After the solidified glass and particulate residue on the fixed sealing surface are cleaned, the cleaning component 10 enters the receiving trough 22 and exits the rising path of the new drawing plate 4. The mounting frame 3 continues to move upward, so that the upper sealing frame of the new drawing plate 4 presses against the cleaned fixed sealing surface at the bottom of the molten material assembly 2. Thus, by using the descending and ascending movement during the replacement of the drawing plate 4, the cleaning component 10 completes the cleaning and scraping work on the fixed sealing surface at the bottom of the molten material assembly 2. This achieves automatic removal of solidified glass and particulate protrusions on the fixed sealing surface before the new drawing plate 4 is lifted, reducing the possibility of the drawing plate 4 being locally raised, tilted, or forming a false fit. This reduces the risk of local gaps and glass melt leakage between the fixed sealing surface and the drawing plate 4.

[0037] Reference Figures 3-5 , Figures 8-9As shown, the transmission assembly includes two sets of pull plates 13 disposed on both sides of the slag receiving plate 5. One end of each set of pull plates 13 is detachably connected to the slag receiving plate 5, and the other end is connected to the traction rope 9. Guide rails 12 are respectively disposed on the inner walls of both sides of the receiving trough 22. Two guide blocks 15 are disposed on the side of each pull plate 13 near the corresponding guide rail 12, which are spaced apart along the direction of movement. The guide blocks 15 slide or roll with the guide rail 12. An elastic element is also connected between the pull plate 13 and the receiving trough 22. When the traction rope 9 is pulled by the trigger plate 8, it drives the pull plate 13 to move towards the melting material assembly 2. When the traction rope 9 is released, the elastic element drives the pull plate 13, the slag receiving plate 5 and the cleaning component 10 back to the receiving trough 22.

[0038] To prevent the cleaning component 10 from cleaning the bottom of the molten material assembly 2 when it extends out of the receiving slot 22, and to clean the bottom of the molten material assembly 2 only when the cleaning component 10 moves back, preferably, refer to Figures 3-9 As shown, a push rod 21 is slidably installed at one end of the guide rail 12 near the melting assembly 2. Two sets of push rods 21 are fixedly connected by a horizontal plate, which is slidably embedded in the side wall of the equipment body 1 and is connected to the equipment body 1 by a spring. A guide plate 18 extending out of the side wall of the equipment body 1 is fixedly installed at the bottom of one set of push rods 21 near the mounting bracket 3. A collar for the traction rope 9 to pass through is provided on the guide plate 18. A fixing buckle 20 is fixedly installed on the traction rope 9. The size of the fixing buckle 20 is larger than the inner hole size of the collar. In this way, when the traction rope 9 is pulled, the traction rope 9 first slides relative to the collar, and when the fixing buckle 20 abuts against the collar, The fixing buckle 20 drives the guide plate 18, the horizontal plate and the top rod 21 to descend, so that the top height of the top rod 21 is level with the bottom height of the guide rail 12. Then the traction rope 9 causes the guide block 15 to move within the guide rail 12 to the end near the end of the molten material assembly 2, that is, the position corresponding to the top rod 21. When the mounting frame 3 rises and the traction rope 9 is released, the top rod 21 resets upward under the action of the spring and pushes the guide block 15 to move upward at the end of the guide rail 12, thereby causing the pull plate 13, the slag receiving tray 5 and the cleaning component 10 to move upward as a whole, so that the cleaning component 10 cooperates with the bottom of the molten material assembly 2, and achieves cleaning of the bottom sealing surface of the molten material assembly 2 during the return stroke.

[0039] Furthermore, the guide rail 12 has a closed loop structure, including a lower feeding section, an outer lifting section near the melting component 2, an upper cleaning section, and an inner descending section away from the melting component 2. The top rod 21 slides vertically into the outer lifting section, and two sets of guide blocks 15 are slidably installed in the guide rail 12. When the mounting frame 3 descends, the trigger plate 8 and the traction rope 9 drive the pull plate 13 to move towards the melting component 2. The two sets of guide blocks 15 first move along the lower feeding section, so that the pull plate 13 extends out at a lower position, and then the slag receiving plate 5 and the cleaning component 10 extend out at a height lower than the bottom of the melting component 2. At this time, the cleaning component 10 is in a yielding state and does not scrape the fixed sealing surface.

[0040] It should be noted that the number of push rods 21 on a set of guide rails 12 can be set to match the number of guide blocks 15. In order to prevent the pull plate 13 from returning to its original position prematurely before the push rods 21 lift the guide blocks 15, a stop block that can elastically extend into the guide rail 12 is provided between the lower feeding section and the outer lifting section of the guide rail 12. The side of the stop block facing the lower feeding section forms an inclined surface. When the guide block 15 moves to the outer lifting section, the guide block 15 pushes the stop block out of the guide rail 12 along the inclined surface; after the guide block 15 passes the stop block, the stop block elastically resets and restricts the guide block 15 from returning in the horizontal direction, so that the push rods 21 can first lift the guide block 15 to the upper cleaning section (the stop block is not shown in the attached figure).

[0041] Subsequently, when the mounting frame 3 moves the new wire drawing plate 4 upward and installs it at the bottom of the molten material assembly 2, the upward movement of the mounting frame 3 causes the traction rope 9 to lose its restraint. During this process, because the guide block 15 is restricted by the stop block, the pull plate 13 cannot elastically reset. Therefore, the top rod 21 elastically moves upward and resets, pushing the guide block 15 through the outer lifting section into the upper cleaning section, causing the pull plate 13, the slag receiving plate 5, and the cleaning component 10 to rise to the cleaning height, that is, the position where the cleaning component 10 is in contact with the fixed sealing surface of the molten material assembly 2. Then the mounting frame 3 continues to rise, the pull plate 13 elastically resets, and the two sets of guide blocks 15 move along the upper cleaning section, causing the cleaning component 10 to be in contact with the fixed sealing surface for scraping and cleaning. When the guide block 15 moves to the end of the guide rail 12 away from the molten material assembly 2, it enters the inner descending section to the lower feeding section by gravity, causing the pull plate 13, the cleaning component 10, and the slag receiving plate 5 to descend and be re-stored in the storage tank 22.

[0042] Furthermore, a side plate 23 is slidably provided at the end of the slag receiving tray 5 away from the cleaning component 10. A square frame 16 is elastically provided at the center of the side plate 23. The square frame 16 is located on the side of the side plate 23 near the cleaning component 10. The square frame 16 can move vertically relative to the side plate 23, and its elastic stroke is adapted to the vertical floating stroke of the cleaning component 10. Two sets of centrally symmetrical support rods 14 are provided between the bottom plate of the cleaning component 10 and the square frame 16. The support rods 14 can slide in the horizontal direction. A positioning component 17 is sleeved on each support rod 14. The positioning component 17 is located near the square frame 16. When the slag receiving tray 5 extends below the fixed sealing surface, the positioning component 17 is located below the side of the fixed sealing surface near the receiving groove 22.

[0043] Reference Figure 3 , Figure 4 , Figure 6As shown, the positioning component 17 includes an L-shaped seat sleeved on the support rod 14, a push block slidably disposed on the L-shaped seat, a threaded rod rotatably connected to the push block and threadedly connected to the L-shaped seat, and a horizontal block slidably disposed on the L-shaped seat. The push block and the horizontal block are provided with mutually cooperating inclined surfaces, and the horizontal block can move vertically on the L-shaped seat. When the threaded rod is rotated, the position of the push block relative to the L-shaped seat can be adjusted, and the height of the horizontal block can be adjusted by the inclined surface cooperation, so that the top of the horizontal block is at a suitable height to the top of the cleaning strip. An elastic telescopic column is provided between the two sets of L-shaped seats to allow the two sets of positioning components 17 to move relatively close or away from each other.

[0044] Furthermore, a separation block 19 is provided below the support rod 14. The separation block 19 is located on the slag receiving plate 5 and is positioned between the positioning member 17 and the square frame 16. The top center of the separation block 19 extends between the two sets of support rods 14. The separation block 19 is provided with an expansion groove that is symmetrical along the center. A semi-circular groove is provided at the bottom of the expansion groove, and the semi-circular groove is positioned close to the center of the separation block 19.

[0045] In practical use, when the mounting frame 3 descends to replace the wire drawing plate 4, the descent of the mounting frame 3 causes the slag receiving plate 5 and the cleaning component 10 to move to the bottom of the melting component 2 via the transmission assembly. At this time, the guide block 15 is at the top of the top rod 21 and is not being pushed upward by the top rod 21; the bottom plate and the square frame 16 are both at the position where the slag receiving plate 5 protrudes to its maximum extent, the two sets of support rods 14 are close to each other, and the top height of the positioning component 17 is flush with the top height of the cleaning strip. Subsequently, after the replacement of the wire drawing plate 4 is completed and it is installed by moving the mounting frame 3 upward, during this process, the top rod 21 pushes the guide block 15 to move the drawing plate 13 and the slag receiving plate 5 upward, thereby causing the cleaning component 10, the positioning component 17, and the square frame 16 to rise, so that the positioning component 17 contacts and adheres to the bottom of the melting component 2. Then, under the action of the upward movement of the slag receiving plate 5, the positioning component 17 moves relative to the separation block 19. The movement is achieved by the expansion groove of the separating block 19, which causes the support rod 14 to move horizontally to both sides. This allows the positioning element 17 to move horizontally to both sides relative to the bottom of the molten material assembly 2. This prevents glass or other particles from being present between the positioning element 17 and the molten material assembly 2 during the initial contact, which would affect the flushing effect between the top of the cleaning element 10 and the bottom of the molten material assembly 2. In other words, the positioning element 17 first contacts the fixed sealing surface and moves in opposite directions, which can remove particles from the initial contact area of ​​the positioning element 17 and reduce the number of particles trapped between the positioning element 17 and the fixed sealing surface, thus affecting the height positioning. After the positioning element 17 is stably attached, the support rod 14 and the square frame 16 together limit the floating height of the cleaning element 10, allowing the cleaning strip to adhere to the fixed sealing surface. Subsequently, the guide block 15 returns along the upper cleaning section, and the cleaning strip performs a covering scraping of the fixed sealing surface. The scraped residue falls into the slag receiving tray 5, which moves synchronously with the cleaning element 10.

[0046] If it is necessary to clean the slag receiving pan 5, remove the slag receiving pan 5 from the pull plate 13, then press the square frame 16 to allow the support rod 14 to slide into the semi-circular groove. At this time, the bottom of the cleaning component 10 is in contact with the bottom of the inner wall of the slag receiving pan 5. Then pull the side plate 23 to move the cleaning component 10 to the outside of the slag receiving pan 5 through the support rod 14, thereby achieving the cleaning of the slag receiving pan 5.

[0047] Reference Figure 1 , Figure 5 , Figure 9 and Figure 10 A limiting plate 11 is elastically slidably embedded in the side wall of the equipment body 1 relative to the mounting frame 3. The limiting plate 11 has an upward-facing inclined surface on the side near the mounting frame 3, and a protrusion at the end of the limiting plate 11 away from the mounting frame 3. The protrusion slides into the guide rail 12 and slides against the guide block 15. In use, when the guide block 15 is at the end of the guide rail 12 away from the melting component 2, the guide block 15 engages with the protrusion, causing the limiting plate 11 to retract entirely within the side wall of the equipment body 1. When the guide block 15 is at the end of the guide rail 12 away from the melting component 2, the guide block 15 cooperates with the protrusion, causing the limiting plate 11 to retract entirely within the side wall of the equipment body 1. When block 15 separates from the protrusion, the limiting plate 11 extends elastically out of the side wall of the main body 1 of the equipment, and its end is on the rising path of the mounting frame 3. In this way, when the cleaning component 10 is not fully retracted into the receiving groove 22, the mounting frame 3 cannot rise to the installation position of the wire drawing plate 4. This avoids the problem that if the cleaning component 10 is not fully retracted into the receiving groove 22 when cleaning the bottom of the molten material assembly 2, the mounting frame 3 will not be able to install the wire drawing plate 4 and may also damage the wire drawing plate 4.

[0048] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.

The automotive headliner fiberglass production line according to claim 1, characterized in that: The slag receiving tray has a side plate slidably disposed at the end away from the cleaning component. A square frame is elastically disposed at the center of the side plate. The square frame is disposed on the side of the side plate close to the cleaning component. Two sets of centrally symmetrical support rods are disposed between the bottom plate of the cleaning component and the square frame. Each support rod is fitted with a positioning component, which is disposed close to the square frame.

7. A glass fiber production line for automotive roof according to claim 6, characterized in that: The positioning component includes an L-shaped seat sleeved on a support rod, a push block slidably disposed on the L-shaped seat, a threaded rod rotatably connected to the push block and threadedly connected to the L-shaped seat, and a horizontal block slidably disposed on the L-shaped seat. The push block and the horizontal block are provided with mutually cooperating inclined surfaces.

8. The automotive headliner glass fiber production line according to claim 6, characterized in that: A separation block is provided below the support rod. The top center of the separation block extends between the two sets of support rods. An expansion groove symmetrically arranged along the center is provided on the separation block. A semi-circular groove is provided at the bottom of the expansion groove.

9. The automotive headliner glass fiber production line according to claim 3, characterized in that: A limiting plate is elastically slidably embedded in the side wall of the main body of the equipment relative to the mounting frame. A protrusion is provided at the end of the limiting plate away from the mounting frame, and the protrusion slides into the guide rail.

10. A processing method for a fiberglass production line for automotive headliners as described in any one of claims 1-9, characterized in that, The process includes the following steps: melting the glass raw material in the melting assembly, forming glass fiber filaments through the drawing spindle, and then drawing and winding them through the winding assembly; When the wire drawing plate needs to be replaced, the mounting frame supporting the original wire drawing plate is lowered to separate the original wire drawing plate from the fixed sealing surface. Then, the mounting frame drives the trigger plate to move down, causing the traction rope to pull the slag receiving tray and cleaning component along the lower section of the guide rail to extend into the lower part of the fixed sealing surface. The new wire drawing plate is then placed under the melting assembly, and the mounting frame is raised to release the traction rope. The top rod pushes the guide block into the upper cleaning section, and the elastic component drives the cleaning component back to the receiving trough to scrape the fixed sealing surface and collect the residue with the slag receiving tray. The guide block returns to the lower receiving section through the inner descending section. After the cleaning component is stored in the receiving trough, the new wire drawing plate continues to rise and presses against the cleaned fixed sealing surface.
