Description

Technical Field

[0001] The invention relates to the technical field of basalt fiber production, in particular to a basalt fiber production device and a production process. Background Art

[0002] Basalt fiber is not only high in strength, but also has many excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. In addition, the production process of basalt fiber determines that less waste is generated and the pollution to the environment is small. After the product is discarded, it can be directly degraded in the environment without any harm. Therefore, it is a truly green and environmentally friendly material.

[0003] After processing, basalt fiber can be widely used in fiber reinforced composite materials, friction materials, shipbuilding materials, thermal insulation materials, automotive industry, high-temperature filter fabrics and protection fields. In friction materials and fiber reinforced composite materials, continuous basalt fibers need to be chopped and then mixed with other materials. Currently, the fibers are chopped in the factory, transported, weighed and mixed. However, since the fibers are very light after chopped, they are always easy to float everywhere during transportation, resulting in a difference between the weight when weighed and the actual weight when added and mixed. Therefore, a device is needed that can cut on site and mix directly after cutting. Summary of the invention

[0010] The beneficial effect is that the hopper chute can be automatically knocked each time the cutting is performed, so that the cut short fiber materials can all fall into the collecting hopper and will not be accumulated on the hopper chute.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 8The basalt fiber production device includes a base frame 1, on which a conveying device 3, a cutting device 2, a turning device 4 and a mixing barrel 5 are arranged. The conveying device 3 includes an upper pulley group 31 and a lower pulley group 32, which are used to transport the basalt fiber line forward to the bottom of the cutting device 2. The cutting device 2 includes a cutting knife 22, a power wheel 21 and a first connecting rod 23. The power wheel 21 provides a power for rotation. A guide groove 11 is arranged at the front end of the base frame 1, and guide sliders 221 are arranged at both ends of the cutting knife 22. The guide slider 221 is arranged in the guide groove 11 through the up and down guide sliding. The outer end of the guide slider 221 is provided with a round shaft 222, a guide slide bar 223 is rotatably arranged on the circular shaft 222, and the lower end of the guide slide bar 223 is slidably arranged on the base frame 1, and a fifth elastic member 224 is sleeved on the guide slide bar 223, and its two ends respectively touch the base frame 1 and the upper end of the guide slide bar 223, and the left and right ends of the cutting knife 22 are provided with guide slide bars 223. At this point, the cutting knife 22 is in an upwardly raised state in the initial state, and the fiber line can pass under its cutting edge. The cutting knife 22 is also provided with a pressure contact block 225, and the pressure contact block 225 is provided with a piston rod 2251, and its piston is slidably arranged in the cutting knife 22 and is located at the front end of the cutting edge.

[0027] In the initial state, the lower end surface of the pressure contact block 225 is lower than the cutting edge. When the cutting knife 22 slides downward, the pressure contact block 225 first presses on the base frame 1, thereby pressing the fiber line on the base frame 1. At this time, the cutting edge of the cutting knife 22 continues to slide downward, the pressure contact block 225 remains stationary, and the piston rod 2251 slides inwardly toward the cutting knife 22. When the cutting edge touches the base frame 1, the cutting edge cuts off the fiber line, thereby completing the cutting work.

[0028] A rotating shaft is arranged on the front end surface of the power wheel 21, and the rotating shaft is not located at the center of the circle. One end of the first connecting rod 23 is rotatably arranged on the rotating shaft, and the other end is rotatably arranged on the circular shaft 222. The power wheel 21 rotates, driving one end of the first connecting rod 23 to make a circular motion, thereby causing the other end thereof to move up and down, so that the cutting knife 22 performs continuous cutting work.

[0029] The power wheel 21 is provided with a sliding slot 211, and a first telescopic member 213 is provided in the sliding slot 211, which is an electric telescopic rod, and the rear end is arranged on the rear end surface of the sliding slot 211, and a tooth block 212 is arranged at the front end of the telescopic rod. When the first telescopic member 213 is extended forward, it can drive the tooth block 212 to extend outward from the surface of the power wheel 21, and when it is retracted, the tooth block 212 is completely immersed in the sliding slot 211, and the power wheel 21 can be evenly provided with a plurality of sliding slots 211, and the first telescopic member 213 and the tooth block 212 are arranged inside.

[0030] The turning device 4 includes a collecting hopper 41, a first rack 42 and a sliding frame 43. The sliding frame 43 is arranged on the side of the base frame 1 and fixedly arranged on the base frame 1. A sliding guide rail 431 is arranged on the sliding frame 43. A first guide groove is provided on the first rack 42. The sliding guide rail 431 is guided and slidably arranged on the sliding guide rail 431 through the first guide groove. A first piston rod 432 is arranged on the rear end plane of the sliding frame 43, and a first cavity 421 and a second cavity 422 are provided inside the first rack 42. The first piston rod 432 guides the piston to slide in the first cavity 421, and a first elastic member 423 is provided in the first cavity 421, and its two ends are respectively in contact with the front end surface of the first cavity 421 and the front end surface of the first piston rod 432. A tooth portion is arranged on the upper end surface of the rack 42. When the tooth block 212 extends outward, the power wheel 21 rotates the tooth block 212 to engage with the tooth portion of the first rack 42, thereby causing the first rack 42 to move backward. A bevel tooth 425 is arranged on the lower end surface of the first rack 42. A second locking member 45 is also arranged on the sliding frame 43, which includes a second telescopic member 451 and a bevel block 452. A guide rod 453 is arranged at the lower end of the bevel block 452. A third cavity is opened in the telescopic rod of the second telescopic member 451. The guide rod 453 is arranged in the third cavity for guiding sliding, and one end of the third elastic member is pressed against the lower end surface of the guide rod 453, and the other end presses against the lower end surface of the third cavity. The front end of the bevel tooth 425 is a straight surface and the rear end is an inclined surface. The front end of the bevel block 452 is an inclined surface and the rear end is a straight surface.

[0031] When the first telescopic member 213 is extended, the power wheel 21 rotates, and the tooth block 212 meshes with the tooth portion of the upper end surface of the first rack 42, thereby driving the first rack 42 to slide backward. During the backward sliding of the first rack 42, the first elastic member 423 is compressed, and at the same time, the inclined surface of the oblique tooth 425 on the lower end surface of the first rack 42 touches the inclined surface of the oblique block 452, so that the oblique block 452 slides downward and allows the oblique tooth 425 to pass. After one oblique tooth 425 passes, the oblique block 452 is lifted upward under the action of the third elastic member. At this time, the tooth block 212 is disengaged from the first rack 42, and the first rack 42 moves forward under the action of the first elastic member 423, and the straight surface of the oblique tooth 425 touches the straight surface of the oblique block 452, so that the second locking member 45 locks the first rack 42, so that when the power wheel 21 rotates, that is, when cutting the fiber line, the first rack 42 can move a certain displacement backward each time it is cut.

[0032] A second piston rod 44 is slidingly provided in the second cavity 422, and a second elastic member 424 is provided in the second cavity 422, and its two ends respectively contact the rear end surface of the second cavity 422 and the front end surface of the second piston rod 44, and a second rack 441 is provided at the rear end of the second piston rod 44. The collecting hopper 41 is rotatably provided at the upper end of the mixing barrel 5, and a first gear 411 is provided on the collecting hopper 41, and the first gear 411 is meshingly connected with the second rack 441, and a first locking member 51 is provided on the mixing barrel 5. The first locking member 51 is an electric telescopic rod, and the telescopic rod thereon extends forward and enters into the rotation track of the tooth portion of the first gear 411, thereby locking the first gear 411. When retracted, the obstacles in the rotation track of the first gear 411 disappear, and thus it is unlocked.

[0033] In the process of the first rack 42 sliding backward, the first gear 411 is locked, so the second piston rod 44 remains stationary. In the process of the first rack 42 moving backward, the second elastic member 424 is compressed, and a first pressure touch switch 433 is provided at the rear end of the sliding frame 43. When the first rack 42 moves to the rear end, it presses on the first pressure touch switch 433, and the first pressure touch switch 433 controls the first locking member 51 to retract. At this time, the first gear 411 is unlocked, that is, the second piston rod 44 is unlocked. Under the action of the second elastic member 424, the second piston rod 44 slides backward. In the process of sliding, the second rack 441 thereon drives the first gear 411 to rotate, and the second rack 441 just rotates the first gear 411 180 degrees from one end to the other, so that the collecting hopper 41 is flipped 180 degrees, and all the fiber short materials cut previously are poured into the mixing barrel 5 below.

[0034] The mixing barrel 5 is provided with an induction switch, and after the collecting hopper 41 flips over for a period of time, the second telescopic member 451 is controlled to retract, so that the inclined block 452 slides downward and leaves the sliding track of the inclined tooth 425, so that the first rack 42 is unlocked, and the first rack 42 slides forward under the action of the third elastic member to return to the initial state. During the recovery process, the first rack 42 moves forward with the second piston rod 44, and the first piston rod 432 is consistent with the second piston rod 44 in length, so the distance the first rack 42 moves forward is just the distance the second piston rod 44 moved backward before. Therefore, during the process of the first rack 42 returning forward, the second piston rod 44 drives the collecting hopper 41 to reverse 180 degrees and return to the initial state, that is, the state of collecting fiber materials.

[0035] When the first pressure-touch switch 433 is pressed, the power wheel 21 stops rotating, and when the first telescopic member 213 retracts, the tooth block 212 is completely immersed in the sliding slot 211, eliminating the influence of the tooth block 212 on the movement of the first rack 42.

[0036] The cutting device 2 also includes a hopper chute 24, which is used to make the cut short fibers automatically slide into the collecting hopper 41. A striking device 25 is arranged on the outside of the hopper chute 24, and the striking device 25 includes a rotating striking rod 251. The middle position of the rotating striking rod 251 is rotatably arranged on the outside of the hopper chute 24. An upper striking plate 241 and a lower bottom plate 242 are arranged on the side of the hopper chute 24. One end of the fourth elastic member 243 is arranged on the lower bottom plate 242, and the other end is arranged on one end of the rotating striking rod 251. One end of the rotating striking rod 251 is in contact with the upper striking plate 241, and the other end of the rotating striking rod 251 is located in the rotation trajectory when the tooth block 212 is extended. The rotating tooth block 212 of the power wheel 21 can touch the rotating striking rod 251.

[0037] When the power wheel 21 rotates, it can drive the front end of the rotating striking rod 251 to move upward, so that the rear end thereof moves downward to compress the fourth elastic member 243. When the tooth block 212 is disconnected from the front end of the rotating striking rod 251, the rear end of the rotating striking rod 251 rebounds upward and hits the upper striking plate 241 under the action of the fourth elastic member 243, thereby vibrating the hopper chute 24 and causing the fiber short materials above to slide into the collecting hopper 41 below, so that the fiber short materials after each cutting can enter the collecting hopper 41 and will not accumulate in the hopper chute 24.

[0038] Its working principle or usage is as follows:

[0039] In the initial state, the first locking piece 51 locks the first gear 411, and the second locking piece 45 locks the first rack 42 forward so that it can only move backward. At the same time, the tooth block 212 extends outward. At this time, the power wheel 21 starts to rotate, driving one end of the first connecting rod 23 to make a circular motion, so that the other end thereof moves up and down, so that the cutting knife 22 performs continuous cutting work, and the cut fiber short materials enter the hopper 41 through the hopper chute 24.

[0040] At the same time, when the power wheel 21 rotates, it can drive the front end of the rotating striking rod 251 to move upward, so that its rear end moves downward to compress the fourth elastic member 243. When the tooth block 212 is disconnected from the front end of the rotating striking rod 251, the rear end of the rotating striking rod 251 rebounds upward and hits the upper knocking plate 241 under the action of the fourth elastic member 243, thereby vibrating the hopper chute 24 and causing the fiber short materials above to slide into the collecting hopper 41 below, so that the fiber short materials after each cutting can enter the collecting hopper 41 and will not accumulate in the hopper chute 24.

[0041] The power wheel 21 rotates, and the tooth block 212 meshes with the teeth on the upper end surface of the first rack 42, thereby driving the first rack 42 to slide backward. During the backward sliding of the first rack 42, the first elastic member 423 is compressed, and at the same time, the inclined surface of the bevel tooth 425 on the lower end surface of the first rack 42 touches the inclined surface of the bevel block 452, so that the bevel block 452 slides downward and allows the bevel tooth 425 to pass. After one bevel tooth 425 passes, the bevel block 452 is lifted upward under the action of the third elastic member. At this time, the tooth block 212 is disengaged from the first rack 42, and the first rack 42 moves forward under the action of the first elastic member 423, and the straight surface of the bevel tooth 425 touches the straight surface of the bevel block 452, so that the second locking member 45 locks the first rack 42, so that when the power wheel 21 rotates, that is, when cutting the fiber line, the first rack 42 can be moved backward by a certain displacement each time it is cut.

[0042] During the backward sliding of the first rack 42, the first gear 411 is locked, so the second piston rod 44 remains stationary. During the backward moving of the first rack 42, the second elastic member 424 is compressed, and a first pressure touch switch 433 is provided at the rear end of the sliding frame 43. When the first rack 42 moves to the rear end, it presses on the first pressure touch switch 433, and the first pressure touch switch 433 controls the first locking member 51 to retract. At this time, the first gear 411 is unlocked, that is, the second piston rod 44 is unlocked. Under the action of the second elastic member 424, the second piston rod 44 slides backward. During the sliding process, the second rack 441 thereon drives the first gear 411 to rotate, and the second rack 441 just rotates the first gear 411 180 degrees from one end to the other, thereby causing the collecting hopper 41 to flip 180 degrees, and all the previously cut fiber short materials are poured into the mixing barrel 5 below.

[0043] After the collecting hopper 41 flips for a period of time, the second telescopic member 451 is controlled to retract, so that the inclined block 452 slides downward and leaves the sliding track of the inclined tooth 425, thereby unlocking the first rack 42. The first rack 42 slides forward under the action of the third elastic member to return to its initial state. During the recovery process, the first rack 42 moves forward with the second piston rod 44, and the first piston rod 432 is the same length as the second piston rod 44. Therefore, the distance the first rack 42 moves forward is just the distance that the second piston rod 44 moved backward before. Therefore, during the process of the first rack 42 returning forward, the second piston rod 44 drives the collecting hopper 41 to reverse 180 degrees and return to its initial state, that is, the state of collecting fiber materials.

[0044] When the first pressure-touch switch 433 is pressed, the power wheel 21 stops rotating, and when the first telescopic member 213 retracts, the tooth block 212 is completely immersed in the sliding slot 211, eliminating the influence of the tooth block 212 on the movement of the first rack 42.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.

When the first rack (42) moves to the rear end, it can press on the first pressure-touch switch (433), thereby controlling the first locking member (51) to retract and unlock the first gear (411).

6. A production process using the basalt fiber production device according to claim 1, characterized in that: S1: Initially, the first locking member (51) locks the first gear (411), and the second locking member (45) locks the first rack (42) so that it can only move backward, and at the same time, the tooth block (212) extends outward; S2: the power wheel (21) rotates to cut the basalt fiber wire and drives the first rack (42) to move backward; S3: When the first rack (42) moves to the end, that is, the cutting quantity reaches the set value, the first locking member (51) is automatically triggered to unlock, so that the first gear (411) is unlocked, so that the second rack (441) drives the collecting hopper (41) to rotate, and the collected fiber short materials are automatically poured into the mixing barrel (5); S4: After the dumping is completed, the second locking member (45) is automatically unlocked, causing the first rack (42) to move forward and return to its initial state. During the recovery process, the second rack (441) is simultaneously driven to move together, so that the second rack (441) drives the collecting hopper (41) to reverse and return to its initial state.
