Description

Technical Field

[0001] This invention relates to the field of glass fiber powder preparation technology, specifically to a melt drawing and pulverizing device for glass fiber powder regeneration. Background Technology

[0002] Glass fiber powder is made by cutting, grinding and sieving specially drawn continuous glass fiber filaments. As a filler and reinforcing material, it is widely used in various thermosetting and thermoplastic resins. Glass fiber powder is used as a filler to improve the hardness and compressive strength of products, and reduce the shrinkage rate, scratch width, wear and production cost of products.

[0003] Waste fiberglass production inevitably produces industrial tailings, which typically account for about 10% to 15% of the total output. In the past, waste fiberglass was disposed of by deep burial in the land, but this method caused serious pollution to the land. With the advancement of technology, waste fiberglass has been transformed into a valuable resource. For example, the fiberglass can be ground into fiberglass powder and used to reinforce nylon, polytetrafluoroethylene, thermoplastic and thermosetting plastics.

[0004] Typically, glass fiber tailings are directly fed into a crushing device for grinding into powder. Due to the fineness of glass fibers, the glass fiber powder produced by the grinding device contains a lot of filamentous glass fibers, which affects the mixing between the glass fiber powder and the raw materials in the later stage. At the same time, some devices have poor grinding and crushing effects when directly crushing glass fiber particles. Finally, in the initial work of the glass fiber drawing process, workers need to use tools to transfer the molten glass falling from a height to a special winding device. Due to the high temperature of the molten glass, there are certain safety hazards during the operation.

[0005] To address this, we propose a melt-drawing and pulverizing device for glass fiber powder regeneration. Summary of the Invention

[0006] The purpose of this invention is to provide a melt drawing and pulverizing device for glass fiber powder recycling, so as to solve the problems mentioned in the background art.

[0007] 1. The rotation of the wheel causes the rotating rod on the entire wheel to move up and down continuously, which in turn drives the conveying rod to rotate, thus achieving the operation of drawing glass in the molten state, avoiding the high risk of manual drawing.

[0008] 2. By melting, drawing, and then crushing the glass fiber tailings, the problem of uneven glass fiber powder that occurs when directly crushing glass fibers is avoided.

[0009] 3. The impact column falls from a height to strike the granular glass fibers placed in the grinding block while simultaneously rotating and grinding them, thus avoiding the problem of insufficient glass fiber breakage.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A melting, drawing, and crushing device for recycling glass fiber powder includes a workbench, a melting box installed on the top of the workbench, and a limiting plate uniformly fixed at the bottom of the melting box by spot welding. A sealing plate is installed on the top of the melting box, and a limit block is fixed on one side of the limiting plate by spot welding. A box body is fixed to the top of the workbench by bolts, and a power mechanism is installed on the inner wall of one side of the box body.

[0012] The power mechanism includes a rotating wheel, a rotating groove, a rotating rod, a movable abutment, and a groove. The rotating wheel is movably connected to one side of the inner wall of the housing via a bearing, and a rotating groove is opened on one side of the rotating wheel. Grooves are symmetrically opened in the rotating groove. A rotating rod is movably connected to one side of the rotating wheel via a bearing, and a movable abutment is slidably connected in the rotating groove.

[0013] A sliding rod is fixed to one side of the inner wall of the box by spot welding, and a sliding sleeve is slidably connected to the sliding rod. A pulling mechanism is installed on one side of the sliding sleeve.

[0014] The pulling mechanism includes a pull plate, a pull groove, a clamping arc plate, an adjusting rod, and a connecting block. The pull plate is fixed to one side of the sliding sleeve by spot welding, and a pull groove is symmetrically opened on one side of the pull plate. A third spring is engaged in the pull groove. The clamping arc plate is slidably connected in the pull groove, and one side of the clamping arc plate is connected to one end of the third spring. An adjusting rod is installed on one side of the pull groove, and one end of the adjusting rod passes through the pull groove and is movably connected to one end of the third spring through a bearing. A knob is fixed to the end of the adjusting rod outside the pull plate by spot welding. A connecting block is fixed to one side of the clamping arc plate by spot welding.

[0015] Furthermore, a transport rod is rotatably connected to one side of the inner wall of the box via a bearing, and one end of the transport rod is slidably connected to one side of the sliding sleeve. One end of the rotating rod is rotatably connected to one side of the transport rod via a bearing, and one side of the connecting block abuts against the limiting block.

[0016] Furthermore, a rotating rod is rotatably connected to one side of the inner wall of the box via a bearing, and a pull rod is symmetrically installed on one side of the rotating rod. A second spring is sleeved on the opposite side of the rotating rod and the pull rod. One end of the pull rod passes through one side of the box and is fixed with a receiving cover by spot welding. One end of the movable abutment is rotatably connected to one side of the rotating rod via a bearing. A first spring is fixed to one side of the inner wall of the box via bolts, and one end of the first spring is connected to one side of the rotating rod.

[0017] Furthermore, the bottom of the workbench is symmetrically connected to guide rollers via bearings, a cooling nozzle is installed on one side of the housing, and a telescopic cutting machine is fixed to the inner wall of the bottom of the workbench with bolts.

[0018] Furthermore, a collection cover is installed at the bottom of the workbench, and collection grooves are provided on both sides of the collection cover. A fixed shell is fixed to the bottom of the workbench by spot welding, and a grinding block is slidably connected inside the fixed shell. A grinding rail is evenly fixed to the top of the grinding block by spot welding.

[0019] Furthermore, the bottom of the worktable is movably connected to a gear via a bearing, and a toothed plate is meshed with one side of the gear. An impact grinding mechanism is installed at the bottom of the toothed plate.

[0020] Furthermore, the impact grinding mechanism includes a support frame, a sliding plate, a connecting column, an arc-shaped connecting groove, an impact column, and an impact protrusion. The bottom of the worktable is fixed to the support frame by spot welding, and the sliding plate is symmetrically slidably connected to the support frame. The opposing surfaces of the two sliding plates are evenly slidably connected to the connecting column. The opposing surfaces of the two sliding plates are fixed to the arc-shaped connecting groove by spot welding. An impact column is installed on one of the sliding plates, and a locking column is symmetrically fixed to the side wall of the impact column by spot welding. The locking column abuts against the arc-shaped connecting groove. One end of the impact column penetrates one side of one of the sliding plates and is fixed to an impact head by spot welding. An impact protrusion is evenly fixed to the outer wall of the impact head by spot welding.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, the rotation of the rotating wheel causes the rotating rod on the entire rotating wheel to continuously move up and down, thereby causing the pull plate connected to one end of the transport rod to move up and down on the surface of the sliding rod. Since the clamping arc plate connected to one end of the entire pull plate is abutted by the limiting block, and with the third spring connected to one side of the clamping arc plate, when the pull plate moves downward, the clamping arc plate pulls the molten glass falling from the melting box. When it moves upward, the clamping arc plate disengages from clamping the glass, thus performing the glass drawing operation in the molten state. At the same time, the entire rotating rod rotates slightly, pulling the two pull rods to move alternately, thus performing the glass drawing operation. Finally, through the action of the cooling nozzle, the rapidly solidified glass wire comes to the guide roller and begins the glass wire cutting operation. Compared with the initial glass drawing operation, which requires the operator to manually draw the wire with tools, the operation risk is lower.

[0023] 2. In this invention, by melting and drawing glass fiber tailings and then crushing them, the texture of the crushed glass fiber powder is more uniform. Compared with directly putting glass fiber into the crushing device for grinding into powder, the glass fiber powder crushed by the grinding device contains more filamentous glass fibers due to the fineness of the glass fiber, which affects the mixing between the glass fiber powder and the raw materials in the later stage.

[0024] 3. In this invention, the filamentous glass fibers are first cut by a telescopic cutting machine, and then the gears rotate to drive the slide plate on the support frame to move upward. Since there are impact columns installed between the slide plates, the impact columns fall from a height to strike the granular glass fibers placed in the grinding block under the action of gravity. At the same time, the impact columns are subjected to the arc-shaped connecting grooves between the slide plates, so that while the impact columns are striking the glass fibers, the impact head starts to rotate and grinds the glass fibers, so that the glass fibers are broken more thoroughly.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-7 The present invention provides a technical solution:

[0035] Example 1:

[0036] In the initial stage of the glass fiber drawing process, workers need to use tools to transfer the molten glass falling from a height to a special winding device. Due to the high temperature of the molten glass, there are certain safety hazards during the operation. At the same time, the preparation of glass fiber powder is similar to the making of dumpling wrappers. The raw materials are first mixed uniformly, then the mixed raw materials are stretched and cut, and finally the cut raw materials are unfolded, instead of directly crushing and unfolding the raw materials. This will result in the crushed raw material particles being mixed with a large number of filaments, which will affect the use of glass fiber powder in the later stage.

[0037] In specific operations, such as Figure 1As shown, workers put the glass fiber tailings into the melting box 2 with the sealing plate 3. The temperature of the entire melting box 2 is raised to 500-750℃ to melt the glass fiber. A high-temperature resistant mesh is installed at the bottom of the melting box 2. The molten glass begins to fall under the action of gravity after passing through the mesh. Since the mesh of one mesh corresponds to the hole formed by the clamping arc plate 163 on the pulling mechanism 16, the molten glass falls slowly at first. At this time, the pulling force is applied manually. However, this device uses the pulling plate 161 to pull it.

[0038] The power mechanism 7 located inside the housing 4 is activated, and the rotating wheel 701 drives the rotating rod 703 to rotate. As the rotating rod 703 rotates, it continuously drives the conveying rod 14 to move up and down on the surface of the slide rod 13. Figure 3-4 As shown, the end of the conveying rod 14 is U-shaped and engages with the sliding sleeve 15 on the slide rod 13. As the conveying rod 14 rotates back and forth, it also drives the sliding sleeve 15 on the slide rod 13 to move up and down. A pull plate 161 is installed on one side of the sliding sleeve 15. The top view cross-sectional structure of the pull plate 161 is shown below. Figure 5 As shown, the connection structure between the end structure of the pull plate 161 and the limiting plate 5 at the bottom of the melting box 2 is as follows: Figure 2 As shown, a third spring 164 is symmetrically installed in the groove 162 within the entire pull plate 161. The clamping arc plate 163 is engaged in the groove 162 and slidably connected to both sides of the groove 162. At the same time, one end of the clamping arc plate 163 is connected to the third spring 164 in the groove 162. When the entire pull plate 161 moves upward, the connecting block 167 at one end of the clamping arc plate 163 is pushed slightly out of the limiting block 6 by the third spring 164. Meanwhile, since the entire limiting block 6 and the connecting block 167 are parallelograms... When the connecting block 167 moves upward, it will be restricted by the edge of the limiting block 6. After the entire clamping arc plate 163 is restricted by the limiting block 6, it will unfold in the groove 162 and pull the third spring 164. When the entire connecting block 167 moves upward to the top of the limiting block 6, the third spring 164 will pull the connecting block 167 to the right. Therefore, the entire connecting block 167 will be subject to the secondary restriction of the limiting block 6. At the same time, the entire clamping arc plate 163 will compress the third spring 164 inward.

[0039] By utilizing the upward movement of the sliding plate 222, the clamping arc plate 163 disengages from the molten glass, and the downward movement of the sliding plate 222 causes the clamping arc plate 163 to pull the molten glass downwards, the mechanical glass drawing operation can be achieved. To further improve the descent speed of the molten glass and the drawing rate, a groove 702 is provided on one side of the rotating wheel 701 when the entire rotating wheel 701 rotates. A recess 705 is also provided within the groove 702, and a movable stop 704 is engaged within the groove 702. One end of the movable stop 704 is rotatably connected to one side of the rotating rod 8. Normally, the first spring 9 installed on one side of the entire housing 4 is connected to one side of the rotating rod 8, while the rotating rod... The other side of the rod 8 is engaged in the rotating groove 702 by the movable abutment 704. The two ensure that the entire rotating rod 8 is perpendicular to the worktable 1. However, when the groove 705 on the rotating wheel 701 coincides with the movable abutment 704, the first spring 9 can pull the entire rotating rod 8 to rotate counterclockwise. At the same time, when the rotating rod 8 rotates, it will also pull the pull rod 10 to move left and right. Since the molten glass first passes through the clamping arc plate 163 and then enters the receiving cover 12 on the pull rod 10, the top pull rod 10 moves to the left a distance and the bottom pull rod 10 moves to the right a distance, which indirectly stretches the glass fiber. The second spring 11 sleeved on the entire pull rod 10 is used for the restoration operation of the pull rod 10.

[0040] After being pulled downwards by the clamping arc plate 163 and extended left and right by the pull rod 10, the molten glass quickly becomes filamentous and falls to the bottom of the worktable 1. The knob 166 and the adjusting rod 165 located on one side of the entire pull groove 162 are used to adjust the clamping degree between the entire clamping arc plate 163 and the glass column. After waiting for a period of time, once the glass falling from the bottom of the molten material box 2 has stabilized, the entire rotating wheel 701 can be closed to prevent the clamping arc plate 163 or the receiving cover 12 from clamping or pulling the glass fiber. The falling glass fiber also needs to be cooled by spraying water mist from the cooling nozzle 17 on one side of the box 4. Finally, the guide roller 18 guides the still unsolidified glass fiber into the collection cover 19 in preparation for the cutting operation.

[0041] Example 2:

[0042] like Figure 6 As shown, a collection groove 20 is provided inside the entire collection cover 19. Through the constraint of the collection groove 20, the glass fibers are concentrated at the bottom of the telescopic cutting machine 21. By controlling the cutting frequency of the telescopic cutting machine 21, the particle size of the glass fiber particles can be adjusted. After the glass fiber particles are cut, they are constrained by the baffle and come to the grinding block 26 at the bottom of the worktable 1. At this time, the preparation of the glass fiber powder begins.

[0043] An impact grinding mechanism 22 is installed on top of the entire grinding block 26. A slide plate 222 on the impact grinding mechanism 22 is fixed to the bottom of the worktable 1 by a support frame 221. A rotatable gear 24 is also installed at the bottom of the worktable 1. Figure 7 As shown, the entire gear 24 has only ordinary tooth patterns. When the toothed plate 23 on the top of the slide plate 222 on the toothed side of the entire gear 24 contacts, the operation of lifting the two slide plates 222 on the support frame 221 can be realized. However, when the other side of the gear 24 has no tooth patterns and contacts the toothed plate 23, the entire slide plate 222 begins to descend under the action of gravity. During the descent, since the two slide plates 222 and the connecting column 223 are fixedly connected, during the descent of the slide plate 222, the bottom of the impact column 225, which is locked on the arc-shaped connecting groove 224 on one side of the slide plate 222, first contacts the grinding block 26. At this time, the impact column 225 stops moving downward. However, the locking column 226 connected on one side of the impact column 225 begins to rotate to the left after being constrained by the arc-shaped connecting groove 224 at the bottom of the top slide plate 222. This drives the impact head 227 connected to one end of the entire impact column 225 to rotate, so that the glass limiting particles can be impacted at the same time as the glass grinding operation can be performed, making the glass fiber particles more thoroughly broken.

[0044] In order to further improve the grinding effect of the entire impact head 227, an impact protrusion 228 with similar tooth pattern is fixed on one side of the impact head 227 by spot welding. At the same time, a grinding rail 27 is set in the entire grinding groove to ensure that the glass fiber is in full contact with the impact head 227, thereby further improving the crushing effect of the glass fiber particles.

[0045] After the crushing process is complete, the workers pull out the grinding block 26 from the fixed shell 25 and pour out the glass fiber powder from the grinding block 26.

[0046] Working principle:

[0047] In use, the operator uses an external lifting and handling device to feed the glass fiber tailings into the melting box 3 and starts the rotating wheel 701 inside the box 4. The rotating wheel 701 drives the rotating rod 703 to rotate. As the rotating rod 703 rotates, it continuously drives the handling rod 14 to move up and down on the surface of the slide rod 13. While the handling rod 14 rotates back and forth, it also drives the sliding sleeve 15 on the slide rod 13 to move up and down. At the same time, the pull plate 161 located on one side of the sliding sleeve 15 moves up and down. At this time, the connecting block 167 at one end of the clamping arc plate 163 is pushed slightly out of the limiting block 6 by the third spring 164. At the same time, since the entire limiting block 6 and the connecting block 167 are parallelograms, When the connecting block 167 moves upward, it will be restricted by the edge of the limiting block 6. After the entire clamping arc plate 163 is restricted by the limiting block 6, it will unfold in the groove 162 and pull the third spring 164 to break away from the clamping action of the molten glass. When the entire connecting block 167 moves upward to the top of the limiting block 6, the third spring 164 will pull the connecting block 167 to the right. Therefore, the entire connecting block 167 will be subject to the secondary restriction of the limiting block 6. At the same time, the entire clamping arc plate 163 will compress the third spring 164 inward. The clamping arc plate 163 will start to pull the molten glass down, realizing the initial wire drawing operation of the glass by the machine.

[0048] When the rotating wheel 701 rotates, a rotating groove 702 is provided on one side of the rotating wheel 701, and a groove 705 is also provided in the rotating groove 702. A movable abutment 704 is engaged in the entire rotating groove 702. One end of the movable abutment 704 is rotatably connected to one side of the rotating rod 8. Under normal conditions, the first spring 9 installed on one side of the entire box 4 is connected to one side of the rotating rod 8, while the other side of the rotating rod 8 is engaged in the rotating groove 702 through the movable abutment 704. The two ensure that the entire rotating rod 8 is perpendicular to the worktable 1. However, when the groove 705 on the rotating wheel 701 coincides with the movable abutment 704, the first spring 9 can pull the entire rotating rod 8 to rotate counterclockwise. At the same time, when the rotating rod 8 rotates, it will also pull the pull rod 10 to move left and right. Since the molten glass first passes through the clamping arc plate 163 and then enters the receiving cover 12 on the pull rod 10, the top pull rod 10 moves to the left a distance and the bottom pull rod 10 moves to the right a distance, which plays a role in stretching the glass fiber a second time.

[0049] The guide roller 18 guides the still-unsolidified glass fiber into the collection hood 19, where it is cut into glass fiber particles by the telescopic cutter 21 at the other end, eventually falling onto the grinding block. At this time, the power unit at one end of the gear 24 is activated. After the toothed side of the gear 24 contacts the toothed plate 23 on the top of the slide plate 222, the operation of lifting the two slide plates 222 on the support frame 221 can be realized. However, when the other side of the gear 24, which has no teeth, contacts the toothed plate 23, the entire slide plate 222 begins to descend under the action of gravity. During the descent, due to the two slide plates 222... 22 is fixedly connected to the connecting post 223. During the descent of the slide plate 222, the bottom of the impact post 225, which is locked on the arc-shaped connecting groove 224 on one side of the slide plate 222, first contacts the grinding block 26. At this time, the impact post 225 stops moving downward. However, the locking post 226 connected to one side of the impact post 225 is constrained by the arc-shaped connecting groove 224 at the bottom of the top slide plate 222 and begins to rotate to the left, thereby driving the impact head 227 connected to one end of the entire impact post 225 to rotate, so that the glass limiting particles can be impacted while glass grinding can be performed.
