Description

Technical Field

[0001] The present invention relates to the technical field of brick-making equipment, and in particular to an automatic brick embryo cutting device. Background Art

[0002] A brick blank, also known as a green body or a green brick; refers to an intermediate product that is processed into a certain shape, size, and strength by means of external force and a mold and can be used for firing; the one without drying is called a wet blank, and the dried one is called a dry blank. Products that can be directly used without firing after forming are called non-fired bricks; during the production process of brick blanks, a brick blank with a larger specification needs to be produced. After the brick blank is initially formed, the brick blank is cut to divide it into multiple brick blank blocks with smaller specifications, and then the brick blank blocks are put into a furnace for sintering. However, due to the influence of its own structure, the existing brick blank cutting device has low cutting efficiency, and the smoothness of the cutting surface of the cut brick blank is low, resulting in partial re-bonding of the adjacent surfaces of the cut brick blanks, reducing the cutting quality of the brick blanks. The publication number is CN211541699U, which discloses a brick blank cutting machine including conveying rollers and an outer frame. In the present invention, an adjusting mechanism is arranged on the top of the cutting knife. By pulling up the T-shaped rod, the round rod at the bottom of the T-shaped rod enters the inner ring of the gear, and then the cutting knife is moved to drive the T-shaped rod to move. At this time, the gear rotates on the rack, and the position of the cutting knife is observed through the scale line. After the adjustment is completed, the pulling force on the T-shaped rod can be cancelled, so that the T-shaped rod moves downward under the action of gravity, and is closely attached to the inner side of the groove through the magnet sheet, and the sliding rod can be driven to move out of the inner side of the sleeve by pulling the pull block. At this time, the spring is compressed by force, and then more cutting knives are installed on the guide rod, achieving the adjustment of the distance between the cutting knives and the number of cutting knives according to actual needs. The automation degree of this cutting machine is insufficient. Although it can adjust the distance between the cutting knives and the number of cutting knives, it is limited by the structure of the cutting knives themselves and the lifting mechanism, resulting in insufficient cutting depth of the cutting knives for the brick blanks, and can only cut brick blanks with smaller specifications, making it difficult to cut brick blanks with larger specifications, and it is not applicable to the production of large brick blanks. Moreover, the adjustability of this cutting machine is low and cannot meet the gradually increasing production requirements. Summary of the Invention

[0027] See the attached Figure 1 To the attached Figure 8 As shown, an automatic brick embryo cutting device includes a base 1, a conveying mechanism, a lifting mechanism, and a plurality of cutting units. The conveying mechanism includes a supporting bracket 21, a first servo motor 23, and a sliding guide rail 22. The supporting bracket 21 is slidably connected to the sliding guide rail 22. The supporting bracket 21 is used to support the brick embryo, and the first servo motor 23 is used to drive the supporting bracket 21 to move. The lifting mechanism includes a lifting guide rail 32 and an adjusting guide rail 34. The lifting guide rail 32 is vertically arranged on the base 1. A lifting frame 321 is slidably connected to the lifting guide rail 32. The adjusting guide rail 34 is arranged on the lifting frame 321 and extends along the length direction of the brick embryo. A plurality of cutting units are slidably connected to the adjusting guide rail 34, and the plurality of cutting units move downward to cut and process the brick blank.

[0028] In this embodiment, the number of sliding guide rails 22 is two. Two sliding guide rails 22 are arranged on the base 1. The two sliding guide rails 22 are arranged horizontally and are spaced apart side by side left and right. The sliding guide rails 22 are perpendicular to the adjusting guide rails 34. Multiple rollers 211 are respectively rotatably connected to the left and right sides of the bottom of the supporting bracket. Each roller 211 is respectively in rolling connection with the sliding guide rail 22.

[0029] In this embodiment, a first screw rod 11 is rotatably connected to the base 1. The first screw rod 11 is parallel to the sliding guide rail 22. The first screw rod 11 is in threaded connection with the supporting bracket. The first servo motor 23 is used to drive the first screw rod 11 to rotate. Specifically, the first servo motor 23 is connected with a driving gear 221. A driven gear 12 is sleeved on the first screw rod 11. The driving gear 221 and the driven gear 12 are connected by a chain. Among them, through the above-mentioned conveying method, the roller method is suitable for transporting brick blanks with large mass to realize the input and output of brick blanks.

[0030] In this embodiment, a plurality of through holes are formed in the supporting bracket 21. The purpose of the through holes is that during the process of removing surface waste and cutting the brick blank, the brick blank debris waste generated can fall out of the supporting bracket 21 through the through holes, preventing the waste from accumulating on the supporting bracket 21, thus affecting the cutting of the brick blank and the input and output of the brick blank, and improving the overall cutting quality.

[0031] In this embodiment, a bracket 31 is arranged on the base 1. A lifting guide rail 32 is arranged on the bracket 31. A second servo motor 33 is arranged on the bracket 31. The second servo motor 33 is connected with a second screw rod 331. The second screw rod 331 is in threaded connection with the lifting frame 321.

[0032] In this embodiment, the cutting unit includes two adjusting seats 41, two translation seats 43, and a cutting wire 46. The number of adjusting guide rails 34 is two. The two adjusting guide rails 34 are arranged on the lifting frame 321 at intervals left and right. An adjusting seat 41 is slidably connected to an adjusting guide rail 34. A translation guide rail 42 is arranged on the adjusting seat 41. The translation guide rail 42 is perpendicular to the adjusting guide rail 34. A translation seat 43 is slidably connected to the translation guide rail 42. The cutting wire 46 is connected between the two translation seats 43.

[0033] In this embodiment, a sliding sleeve 44 is provided on the adjusting seat 41. A sliding groove 441 is formed on the outer side wall of the sliding sleeve 44. The sliding groove 441 spirally extends along the length direction of the translation guide rail. Both ends of the cutting wire 46 are respectively connected with sliding blocks 45. The sliding blocks 45 slide within the sliding sleeve 44. A first connecting block 431 is provided on the translation seat 43. The end of the sliding block 45 is rotatably connected to the first connecting block 431. A sliding sub 451 is rotatably connected to the outer side wall of the sliding block 45. The sliding sub 451 slides within the sliding groove 441 and is in rolling contact with the sliding groove 441. The adjusting seat 41 is provided with a second connecting block 411. A transmission gear 412 is rotatably connected to the second connecting block 411. A connecting bump 4121 is formed on the transmission gear 412. The connecting bump 4121 is hinged with a second connecting rod 413. A third connecting block 432 is provided on the translation seat 43. The second connecting rod 413 is hinged with the third connecting block 432. By rotating the transmission gear 412, the cutting wire 46 is driven to move back and forth and rotate in both forward and reverse directions. Among them, the moving direction of the cutting wire 46 is parallel to the length direction of the translation guide rail 42.

[0034] In this embodiment, a plurality of first fixing holes 341 are formed on the adjusting guide rail 34. The plurality of first fixing holes 341 are arranged at intervals in sequence along the length direction of the adjusting guide rail 34. A second fixing hole 414 is formed on the adjusting seat 41. The adjusting seat 41 is fixed by inserting pins through the second fixing hole 341 and the first fixing hole 414 in sequence. Among them, when it is necessary to adjust the distance between two adjacent cutting units, by pulling out the pins on the two adjusting seats 41 of the corresponding cutting unit, the pins are withdrawn from the first fixing hole 414 and the second fixing hole 341 in sequence. At this time, the distance between the two cutting units can be adjusted, and the adjusting seat 41 can be pushed to move to achieve this.

[0035] In this embodiment, two driving motors 35 are provided on the lifting frame 321. The driving motor 35 is connected with a driving reduction gearbox 351. The driving reduction gearbox 351 has a transmission shaft 36. A convex tooth portion 361 is formed on the transmission shaft 36. The convex tooth portion 361 is annularly distributed in the circumferential direction of the transmission shaft 36. The convex tooth portion 361 extends parallel to the axis direction of the transmission shaft 36. The convex tooth portion 361 meshes with the transmission gear 412.

[0036] In this embodiment, the length of the transmission shaft 36 is greater than the length of the adjusting guide rail 34. In this way, the extending length of the convex tooth portion 361 of the longer transmission shaft 36 can be greater than the length of the adjusting guide rail 34. Thus, when adjusting the distance between the two cutting units, no matter where the adjusting seat 41 moves to any position on the adjusting guide rail 34, the convex tooth portion 361 can still mesh with the transmission gear 412, so as to ensure that the transmission shaft 36 can synchronously drive a plurality of transmission gears 412 to rotate, thereby driving a plurality of cutting wires 46 to move back and forth synchronously and rotate back and forth in both forward and reverse directions.

[0037] In this embodiment, elastic buffer members may be provided at the foremost end and the rearmost end of the sliding groove 441. In this way, when the sliding member 451 moves to the foremost end and the rearmost end of the sliding groove 441, it can play a buffering role, thereby reducing the collision between the sliding member 451 and the sliding groove 441 and improving the overall service life. At the same time, since the sliding member 451 is rotatably connected to the sliding block 45, when the sliding member 451 slides in the sliding groove 441, the sliding member 451 can be in rolling connection with the side wall of the sliding groove 441 by virtue of its rotatability. In this way, the sliding speed and smoothness of the sliding member 451 are improved, and the friction between the sliding member 451 and the sliding groove 441 is reduced, making the rotation of the sliding block 45 in the sliding sleeve 44 smoother.

[0038] In this embodiment, in the same cutting unit, to ensure the synchronization of both ends of the cutting wire 46 for facilitating the cutting process of the brick blank, drive gears 412, second connecting rods 413, and third connecting blocks 432 need to be provided on both adjusting seats 41 in the same cutting unit. In this way, the translation seats 42 at both ends can continuously tighten the sliding block 45, thereby achieving the common tightening of the cutting wire 46.

[0039] In this embodiment, the specific brick blank cutting process is as follows: The brick blank to be cut is pre-formed in a mold with a certain hardness and stability and will not be damaged due to the cutting by the cutting unit. After forming, the mold is disassembled, and then the brick blank to be cut is hoisted and moved by a gantry crane.

[0040] Preparation before cutting: First, according to the thickness of the brick blank to be cut, adjust the distance between multiple cutting units. Specifically, pull out the pins on the adjustment seats 41 of the corresponding cutting units respectively, so that the pins sequentially exit the first fixing holes 414 and the second fixing holes 341, thereby making the two adjustment seats 41 of the cutting unit movable. Then, push the two adjustment seats 41 of the corresponding cutting unit to move on the adjustment guide rail 34 until the two adjustment seats 41 of the cutting unit move to the set position, and align the second fixing hole 414 of the adjustment seat 41 downward with the first fixing hole 341 on the corresponding adjustment guide rail 34. Then, reinsert the pins through the second fixing hole 341 and the first fixing hole 414 in sequence to fix the adjustment seat 41 on the adjustment guide rail 34 and restrict the movement of the adjustment seat 41. In this way, the distance between two adjacent cutting units is adjusted, thereby adjusting the distance between two adjacent cutting lines 46, facilitating the subsequent cutting of brick blanks with different thicknesses. Among them, when the adjustment seat 41 moves, the transmission gear 412 on the adjustment seat 41 also moves accordingly. At this time, since the convex tooth portion 361 extends parallel to the axis of the transmission shaft 36, when the adjustment seat 41 moves to any position on the adjustment guide rail 34, the convex tooth portion 361 can be engaged with the transmission gear 412. In this way, it is ensured that no matter where the adjustment seat 41 moves to, the convex tooth portion 361 of the transmission shaft 36 can drive the transmission gear 412 to rotate, thereby driving the cutting line 46 to move back and forth for cutting, meeting the thickness specifications of various brick blanks required for adjustment, with strong adjustability and adaptability.

[0041] Cutting the brick blank: After the adjustment is completed, it is necessary to input the brick blank to be cut. At this time, the bearing bracket 21 is located on the front side of the support 31. Place the brick blank to be cut on the bearing bracket 21 by means of a gantry crane or the like. Then, start the first servo motor 22. The first servo motor 22 drives the driving gear 221 to rotate. The driving gear 221 drives the driven gear 12 to rotate through a chain, so as to drive the first screw rod 11 to rotate, realizing driving the bearing bracket 21 to move forward to input the brick blank to be cut until the bearing bracket 21 moves to directly below the lifting frame 321 and multiple cutting units. Then, start the second servo motors 33 respectively. The second servo motors 33 drive the second screw rods 331 to rotate. The second screw rods 331 drive the lifting frame 321 and multiple cutting units to move downward.

[0042] Synchronously, the driving motor 35 is started. The driving motor 35 drives the driving reduction gearbox 351 to work. The driving reduction gearbox 351 drives the transmission shaft 36 to rotate. The transmission shaft 36 drives a plurality of transmission gears 412 to rotate through the convex tooth portion 361. The transmission gears 412 rotate to drive the second connecting rod 413 to swing back and forth. The second connecting rod 413 drives the third connecting block 432 to move, so that the translation seat 43 moves back and forth on the translation guide rail 42. At this time, due to the back-and-forth movement of the translation seat 43, the first connecting block 431 on the translation seat 43 will be driven to move back and forth, so that the first connecting block 431 drives the cutting wire 46 to move back and forth. And because the sliding element 451 on the sliding block 45 slides in the sliding groove 441 on the sliding sleeve 44 of the adjusting seat 41, and the sliding groove 441 spirally extends along the length direction of the translation guide rail, the sliding block 45 moves back and forth in the sliding sleeve 44 along a spiral trajectory. Thus, while the cutting wire 46 moves back and forth horizontally, it can also rotate back and forth in the positive and negative directions. In this way, when the cutting wire 46 moves downward and contacts the brick blank, the second servo motor 33 continues to drive the lifting frame 321 and the plurality of cutting wires 46 to continue to move downward. With the back-and-forth horizontal movement and the back-and-forth rotation in the positive and negative directions of the cutting wire 46, vertical cutting processing of the brick blank is realized.

[0043] Output of the cut brick blank: After cutting is completed, the second servo motor 33 is controlled to drive the lifting frame 321 to move upward and reset, so that the plurality of cutting wires 46 move upward to leave the cut brick blank. Then the first servo motor 14 is started. The first servo motor 22 drives the first screw rod 11 to continue to rotate. The first screw rod 11 drives the bearing bracket 21 to continue to move forward, realizing the output of the cut brick blank until the bearing bracket 21 completely leaves directly below the lifting frame 321 and moves to the rear side of the support 31. Finally, the cut brick blank is removed from the bearing bracket 21 by means of a gantry lifting frame or the like, facilitating the output of the cut brick blank and preventing the cut brick blank from separating during output.

[0044] Among them, the two sliding blocks 45 and the two sliding sleeves 44 in the same cutting unit are distributed at intervals left and right. When the sliding element 451 of the sliding block 45 on the left is at the forefront of the sliding groove 441 of the sliding sleeve 44, the sliding element 451 of the sliding block 45 on the right is also at the rearmost end of the sliding groove 441 of the sliding sleeve 44. When the sliding element 45 moves to the forefront of the sliding groove 441, it returns until the sliding element moves to the rearmost end of the sliding groove 441. When the sliding element 451 of the sliding block 45 on the left is at the rearmost end of the sliding groove 441 of the sliding sleeve 44, the sliding element 451 of the sliding block 45 on the right is also at the forefront of the sliding groove 441 of the sliding sleeve 44; At the same time, when the sliding element 451 of the sliding block 45 moves from the forefront of the sliding groove 441 of the sliding sleeve 44 to the rearmost end of the sliding groove 441, in cooperation with the sliding block 45 being rotatably connected to the first connecting block 431, the sliding block 45 rotates in the positive direction with the cutting wire 46. Among them, by utilizing the characteristic that the cutting line 46 can move back and forth, the cutting of the green brick by the cutting line 46 is realized. At the same time, in cooperation with the characteristic that the cutting line 46 can rotate back and forth in both forward and reverse directions, the cutting surface of the green brick after cutting can be made smoother, the resistance of the cutting line 46 to cut the green brick is smaller, the cutting of the green brick is smoother, the unilateral wear of the cutting line 46 is reduced, and the blank remaining on the cutting line 46 after the green brick is cut is reduced.

[0045] The above-described embodiments are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Any person skilled in the art can make more possible changes and modifications to the technical solution of the present invention by using the disclosed technical content without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes.
