Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a cutting device for autoclaved aerated concrete block blanks. Background Art

[0002] Autoclaved aerated concrete block blanks are produced through processes such as batching, resting, cutting, shaping, autoclaving, and storage using raw materials such as fly ash, sand, and cement. During cutting, generally, a tightened steel wire is used for cutting. For example, a foamed brick cutting device disclosed in a patent application with the publication number CN204414318U includes a trench, tracks symmetrically arranged on both sides of the trench, a foamed brick moving flatbed truck slidably installed on the tracks, and cutting devices A, B, and C installed at intervals along both sides of the tracks; a groove is provided on the track at one end of the cutting device C, and a stop plate is movably installed in the groove through a pin shaft and a spring, and a notch is provided on the track at the other end of the cutting device C, and a limiting plate is movably inserted into the notch. This foamed brick cutting device has a simple structure and solves the problem that the existing pallet will move forward due to inertia, resulting in inaccurate stopping positions of the pallet, uneven specifications of the cut small blocks, and a high rejection rate. This foamed brick cutting device can make the stopping position of the foamed brick moving flatbed truck accurate through the limiting plate and the stop plate, thereby effectively improving the product quality and reducing the rejection rate.

[0003] The above-mentioned cutting device can cut autoclaved aerated concrete block blanks, but during the cutting process, the cutting steel wire needs to cut into the autoclaved aerated concrete block blank, and the surface of the cutting steel wire will be contaminated with the blank after cutting. If it is not cleaned, the blank will dry and adhere to the surface of the cutting steel wire. After multiple cuttings, the diameter of the cutting steel wire will become thicker, and due to the uneven surface of the cutting steel wire after the dried blank adheres, the cutting resistance of the cutting steel wire will increase. When the cutting resistance increases, on the one hand, the cutting force will decrease, making it inconvenient to cut; on the other hand, the force exerted by the blank on the cutting steel wire will increase, resulting in the cutting steel wire being prone to breakage and a short service life of the cutting steel wire. Therefore, it is necessary to redesign a cutting device for autoclaved aerated concrete block blanks to solve the above problems. Summary of the Invention

[0004] The purpose of the utility model is to provide a cutting device for autoclaved aerated concrete block blanks that can ensure the cutting force and effectively extend the service life of the cutting steel wire.

[0005] The technical solution of the utility model is as follows:

[0007] The wire brush consists of an assembly ring, a support ring and brush filaments. The support ring is fixedly installed on the assembly ring through fixing bolts, and brush filaments are arranged on the inner wall of the support ring; the assembly ring is fixedly connected to the support frame.

[0009] Limit groove wheels are symmetrically arranged on the support frame, and the limit groove wheels are slidably connected to the cutting wires.

[0010] The beneficial effects of the present utility model are as follows:

[0019] The cutting device for autoclaved aerated concrete block blanks includes a support frame 1 and a cutting wire 2. The cutting wire 2 is arranged at the rear end of the support frame 1 to cut the autoclaved aerated concrete block blanks through the cutting wire 2. Support plates 3 are respectively arranged on both sides of the support frame 1. The ends of the support plates 3 are movably installed with cylinders 4 through pins. Wire brushes 5 are respectively arranged on both sides of the support frame 1 inside the cylinders 4. The two ends of the cutting wire 2 respectively pass through the wire brushes 5 and are fixedly connected with the ends of the piston rods of the cylinders 4 through connectors 6. The function of the cylinder 4 is, on the one hand, to tighten the cutting wire 2 through the cylinder 4, so as to facilitate the cutting wire 2 to cut the autoclaved aerated concrete block blanks; on the other hand, the cylinder 4 can pull the cutting wire 2 to move, so that when the cutting wire 2 moves through the wire brush 5, the blank on the surface of the cutting wire 2 can be timely brushed off before drying by the wire brush 5, thereby ensuring the cutting ability of the cutting wire 2 and facilitating cutting; and reducing the force on the cutting wire 2 during the cutting process, making the cutting wire 2 not easily break, and effectively extending the service life of the cutting wire 2.

[0020] The wire brush 5 is composed of an assembly ring 501, a support ring 502 and brush wires 503. The support ring 502 is fixedly installed on the assembly ring 501 through fixing bolts. Brush wires 503 are arranged on the inner wall of the support ring 502; the assembly ring 501 is fixedly connected with the support frame 1. Since the support ring 502 is connected with the assembly ring 501 through fixing bolts, the support ring 502 can be disassembled and replaced, so that the brush wires 503 can be replaced, so that after the wire brush works for a long time, the brushing ability of the wire brush can be maintained by replacing the brush wires 503, ensuring that the blank on the surface of the cutting wire 2 can be brushed off.

[0021] A limit grooved pulley 8 is arranged on the support frame 1 between the wire brush 5 and the cylinder 4. The limit grooved pulley 8 is slidably connected with the cutting wire 2. The function of the limit grooved pulley 8 is to limit the cutting wire 2 through the limit grooved pulley 8, prevent the cutting wire 2 from shifting up and down during the cutting process, and further ensure the cutting accuracy and improve the finished product yield.

[0022] When the cutting device for the autoclaved aerated concrete block blank cuts, the cylinder 4 tightens both ends of the cutting wire 2 to make the cutting wire 2 straight. When the autoclaved aerated concrete block blank passes through the cutting wire 2 driven by the trolley, the cutting wire 2 cuts the autoclaved aerated concrete block blank.

[0023] After the cutting of the autoclaved aerated concrete block blank is completed, the cylinder 4 on one side of the support frame 1 pulls the cutting wire 2, and at the same time, the piston rod of the cylinder 4 on the other side of the support frame 1 extends to release the cutting wire 2. The cutting wire 2 moves towards the cylinder 4 that pulls the cutting wire 2. When the cutting wire 2 passes through the wire brush 5 during the movement, the wire brush 5 cleans the surface of the autoclaved aerated concrete block blank contaminated on the cutting wire 2. After the cylinder 4 on one side of the support frame 1 moves to the limit position, the cylinder 4 on the other side of the support frame 1 pulls the cutting wire 2 to move and cleans the other part of the cutting wire 2.

[0024] The cutting device for the autoclaved aerated concrete block blank can cut the autoclaved aerated concrete block blank through the cutting wire 2 when the autoclaved aerated concrete block blank passes through the cutting wire 2. The blank on the surface of the cutting wire can be removed through the wire brush 5, so that the blank is not easy to dry and adhere to the surface of the cutting wire 2, maintaining the diameter and surface flatness of the cutting wire 2, which can greatly reduce the cutting resistance of the cutting wire and the acting force on the cutting wire, so as to maintain the cutting force, facilitate cutting, and effectively extend the service life of the cutting wire. It solves the problems that after multiple cuts by the existing cutting device, the cutting resistance is large, resulting in inconvenient cutting and short service life of the cutting wire. Embodiment 2

[0025] The cutting device for the autoclaved aerated concrete block blank includes a support frame 1 and a cutting wire 2. The cutting wire 2 is arranged at the rear end of the support frame 1 to cut the autoclaved aerated concrete block blank through the cutting wire 2. Support plates 3 are respectively arranged on both sides of the support frame 1. The ends of the support plates 3 are movably installed with cylinders 4 through pins. The end of the piston rod of the cylinder 4 is connected with the cutting wire 2 through a connector 6; vibrators 7 are respectively arranged on both sides of the support frame 1 inside the cylinder 4, and the vibrators 7 are in contact connection with the cutting wire 2. The vibrator 7 includes a vibration housing, a motor and an eccentric rotor. Due to the eccentricity of the eccentric rotor, vibration is generated when the motor drives the eccentric rotor to rotate. The function of the cylinder 4 is, on the one hand, to tighten the cutting wire 2 through the cylinder 4, so as to facilitate the cutting wire 2 to cut the autoclaved aerated concrete block blank; on the other hand, the cylinder 4 can pull the cutting wire 2 to move, so that when the cutting wire 2 moves through the vibrator 7, the blank on the surface of the cutting wire 2 is removed before drying through the vibration of the vibrator 7, thereby ensuring the cutting ability of the cutting wire 2 and facilitating cutting; and reducing the acting force on the cutting wire 2 during the cutting process, making the cutting wire 2 not easy to break and effectively extending the service life of the cutting wire 2.

[0026] A limiting groove wheel 8 is provided on a support frame 1 between a vibrator 7 and a cylinder 4, and the limiting groove wheel 8 is slidably connected to a cutting wire 2. The function of the limiting groove wheel 8 is to limit the cutting wire 2 through the limiting groove wheel 8, prevent the cutting wire 2 from shifting up and down during the cutting process, thereby ensuring the cutting accuracy and improving the yield of finished products.

[0027] When the cutting device for the autoclaved aerated concrete block blank cuts, the cylinder 4 tightens both ends of the cutting wire 2 to make the cutting wire 2 straight. When the autoclaved aerated concrete block blank passes through the cutting wire 2 driven by a trolley, the cutting wire 2 cuts the autoclaved aerated concrete block blank.

[0028] After the cutting of the cutting device for the autoclaved aerated concrete block blank is completed, the cylinder 4 on one side of the support frame 1 pulls the cutting wire 2, and at the same time, the piston rod of the cylinder 4 on the other side of the support frame 1 extends to release the cutting wire 2. The cutting wire 2 moves towards the cylinder 4 that pulls the cutting wire 2. When the cutting wire 2 passes through the vibrator 7 during the movement of the cutting wire 2, the vibrator 7 performs surface cleaning on the autoclaved aerated concrete block blank contaminated on the cutting wire 2 through vibration. After the cylinder 4 on one side of the support frame 1 moves to the limit position, the cylinder 4 on the other side of the support frame 1 pulls the cutting wire 2 to move and cleans the other part of the cutting wire 2.

[0029] The cutting device for the autoclaved aerated concrete block blank can cut the autoclaved aerated concrete block blank through the cutting wire 2 when the autoclaved aerated concrete block blank passes through the cutting wire 2. The vibrator 7 can remove the blank on the surface of the cutting wire 2, making it difficult for the blank to dry and adhere to the surface of the cutting wire 2, maintaining the diameter and surface flatness of the cutting wire 2, greatly reducing the cutting resistance of the cutting wire 2 and the acting force on the cutting wire 2, thereby being able to maintain the cutting force, facilitating cutting, and effectively extending the service life of the cutting wire 2. It solves the problems of large cutting resistance and inconvenient cutting after multiple cuts of the existing cutting device, and short service life of the cutting wire.
