Description

Technical Field

[0001] The invention relates to the technical field of aerated brick production equipment, and in particular to an aerated brick cutting device. Background Art

[0002] As is known, aerated bricks are usually first prepared into larger blanks in a mold, the initially solidified aerated bricks are taken out of the mold and accurately positioned, and a cutting device is used to perform transverse and longitudinal cutting according to predetermined sizes, and then excess materials and debris are cleaned up, and the size after cutting is checked to see if it meets the standard; however, the existing cutting device still has shortcomings, which restricts the production efficiency of aerated bricks.

[0003] A Chinese patent (publication number: CN219666990U) discloses a longitudinal cutting device for aerated brick processing; the patent includes a mounting frame, the inner wall of which is equipped with a pressing mechanism. This pressing mechanism is composed of a sliding seat, and a cutting assembly is provided on one side of the sliding seat. The cutting assembly is mainly composed of a mounting frame, a mounting seat, a support roller shaft and a steel wire; one side of the mounting seat is also equipped with a first adjustment mechanism and a second adjustment mechanism, wherein the second adjustment mechanism specifically includes a hydraulic rod B and a distance sensor; the first adjustment mechanism can realize automatic adjustment of the tension of the steel wire, and the second adjustment mechanism is used to automatically adjust the position of the steel wire, which enables the equipment to conveniently adjust the cutting size; the first adjustment mechanism and the second adjustment mechanism complement each other and can quickly complete the adjustment of the tension and position of the steel wire; During the cutting operation, the vibrator drives the mounting frame to vibrate through the connecting bracket, thereby driving the mounting frame to move back and forth horizontally on the sliding seat, so that the steel wire moves in the vertical direction and also in the horizontal direction, so that the aerated brick blank is not easily deformed when being cut; however, in actual use, it is found that if the power of the vibrator is relatively small, the reciprocating motion stroke of the steel wire is relatively small, and it is difficult to form a sawing effect; if the power of the vibrator is relatively large, the overall vibration of the equipment is relatively large, which will generate relatively large noise; in addition, the patent cannot effectively prevent the steel wire from breaking due to large force, and it is impossible to detect and make adjustments in time when the steel wire breaks. Summary of the invention

[0004] In order to overcome the deficiencies in the background technology, the present invention discloses an aerated brick cutting device.

[0005] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme: An aerated brick cutting device comprises a base, a guide rail column, a cutting frame and a cutting mechanism; a cutting frame capable of vertical lifting is provided on the top of the base; a plurality of cutting mechanisms are provided at intervals along the length direction of the cutting frame; The cutting mechanism comprises a cutting wire that movably passes through the cutting frame, a pulling device disposed on one side of the cutting frame, and a retracting device disposed on the other side of the cutting frame; The pulling device comprises a box body, one end of which is slidably fitted with a slider capable of pulling the cutting wire, and the other end of which is provided with an electromagnet capable of attracting the slider to move; The reeling device comprises a wheel frame which is correspondingly and firmly connected to the cutting frame, the wheel frame is rotatably connected to a reeling wheel for reeling in the cutting wire, and a torsion spring for automatically reeling in the reeling wheel is arranged between the reeling wheel axle and the wheel frame.

[0006] Preferably, two guide pillars are spaced apart in the box body, and the slider is correspondingly slidably matched with the two guide pillars.

[0007] Preferably, buffer springs are sleeved on both ends of the guide column body corresponding to the sliding block.

[0008] Preferably, the slider is correspondingly connected to the cutting wire through a tension sensor.

[0009] Preferably, a cutting frame is arranged on the top of the base via four guide rail columns, and a driving device for driving the cutting frame to move vertically up and down along the guide rail columns is arranged inside the guide rail columns.

[0010] Preferably, the driving device is a telescopic cylinder or a screw-nut mechanism driven by a motor.

[0011] Preferably, a guide rail is provided on the top of the base.

[0012] Preferably, a cleaning device for cleaning the cutting wire is provided in the cutting frame; the cleaning device comprises a cleaning frame with two ends correspondingly slidingly matched with the cutting frame, and the cleaning frame is equipped with a brush for cleaning the cutting wire.

[0013] Due to the adoption of the above-mentioned technical solution, the present invention has the following beneficial effects: The invention discloses an aerated brick cutting device, which has a simple structure, is easy to assemble and has a low production cost. The cutting frame is provided with a plurality of cutting mechanisms at intervals along the length direction. As the cutting frame moves downward, the cutting wire reciprocates under the coordinated action of a pulling device and a winding device, thereby forming a sawing effect on the aerated brick blank. On the one hand, the cutting efficiency is improved and the flatness of the cut end face is improved. On the other hand, the reaction force on the cutting wire is reduced to avoid the breaking of the cutting wire.

[0014] The present invention further enables the slider to be correspondingly connected to the cutting wire through a tension sensor, that is, the tension of the cutting wire can be monitored in real time through the tension sensor; during normal cutting operation, the tension on the cutting wire is within a set threshold range. When the tension on the cutting wire exceeds the set threshold range, it indicates that the cutting frame moves down too fast, or foreign matter is contained in the aerated brick blank, and the cutting encounters resistance; when the tension on the cutting wire is lower than the set threshold range, it indicates that the cutting wire is broken, that is, the operating state of the cutting wire can be judged by the tension value fed back by the tension sensor, so that the operator can make corresponding adjustments in time.

[0015] The present invention further provides a cleaning device for cleaning the cutting wire in the cutting frame; the cleaning device comprises a cleaning frame with two ends correspondingly slidingly matched with the cutting frame, and the cleaning frame is equipped with a brush for cleaning the cutting wire, that is, after the cutting operation, the operator can control the cleaning frame to move along the cutting frame, and the cleaning frame drives the brush to clean the cutting wire, thereby ensuring the cleanliness of the cutting wire; in order to further improve automation, the cleaning frame can be driven to move back and forth by a telescopic cylinder to clean the cutting wire.

DETAILED DESCRIPTION

[0018] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0019] Embodiment 1, in combination with Figures 1 to 3, an aerated brick cutting device, used for vertically cutting aerated brick blanks, comprises a base 1, a guide rail column 2, a cutting frame 3 and a cutting mechanism; a cutting frame 3 capable of vertical lifting is provided on the top of the base 1, and there are many mechanisms capable of vertically lifting the cutting frame 3, such as a gantry is provided on the top of the base 1, and a telescopic cylinder for driving the cutting frame 3 to vertically lift is installed in the gantry; preferably, a cutting frame 3 is provided on the top of the base 1 through four guide rail columns 2, and a driving device for driving the cutting frame 3 to vertically move up and down along the guide rail columns 2 is provided in the guide rail columns 2, and the driving device is a telescopic cylinder or a screw nut mechanism driven by a motor; the cutting frame 3 is slidably matched with the four guide rail columns 2, which can effectively ensure the stability of the vertical lifting of the cutting frame 3; as shown in the attached Figure 1 As shown, in order to ensure the stability of the four guide rail columns 2, a connecting beam is provided at the top of the four guide rail columns 2, and an inclined steel cable is installed between the guide rail columns 2 and the base 1 to further improve the stability and structural strength of the four guide rail columns 2; a guide rail 7 is set on the top of the base 1, that is, the trolley for transporting aerated brick blanks can move along the guide rail 7 to the bottom of the cutting frame 3 and wait for cutting operation.

[0020] The cutting frame 3 is provided with a plurality of cutting mechanisms at intervals along the length direction; the cutting mechanism comprises a cutting wire 4 which is movable through the cutting frame 3, a pulling device 5 arranged on one side of the cutting frame 3 and a retracting device 6 arranged on the other side of the cutting frame 3, that is, during the cutting operation, the driving device drives the cutting frame 3 to move downward from the top of the aerated brick blank, and the cutting wire 4 cuts the aerated brick blank; as the cutting frame 3 moves downward, the cutting wire 4 moves back and forth under the coordinated action of the pulling device 5 and the retracting device 6, thereby forming a sawing effect on the aerated brick blank, which improves the cutting efficiency and the flatness of the cut end face on the one hand, and reduces the reaction force on the cutting wire 4 on the other hand, and avoids the cutting wire 4 from breaking; after cutting to the bottom of the aerated brick blank, the driving device drives the cutting frame 3 to rise until it is even above the aerated brick blank, and then waits for the next group of aerated brick blanks to be cut.

[0021] As attached Figure 2 As shown, the pulling device 5 comprises a box body 5-1, one end of which is slidably fitted with a slider 5-2 capable of pulling the cutting wire 4, and the other end of the box body 5-1 is provided with an electromagnet 5-3 capable of attracting the slider 5-2 to move, that is, the electromagnet 5-3 can attract the slider 5-2 by energizing the electromagnet 5-3, and the slider 5-2 drives the cutting wire 4 to move; In order to ensure the stability of the movement of the slider 5-2, two guide pillars 5-4 are arranged in the box body 5-1, and the slider 5-2 slides with the two guide pillars 5-4; buffer springs 5-5 are sleeved on both ends of the guide pillars 5-4 corresponding to the slider 5-2, which can prevent the slider 5-2 from colliding with the box body 5-1 or the electromagnet 5-3, thereby reducing the noise during the cutting operation; As attached Figure 3 As shown, the reeling device 6 comprises a wheel frame 6-1 which is fastened to the cutting frame 3, the wheel frame 6-1 is rotatably connected to a reeling wheel 6-2 for reeling in the cutting wire 4, and a torsion spring for automatically reeling the reeling wheel 6-2 is provided between the wheel axle of the reeling wheel 6-2 and the wheel frame 6-1, the torsion spring can be replaced by a coil spring, and the function is to drive the reeling wheel 6-2 to automatically reel in the cutting wire 4; When the electromagnet 5-3 is powered off and loses its attraction to the slider 5-2, the take-up wheel 6-2 reels part of the cutting wire 4 under the action of the torsion spring. When the electromagnet 5-3 is powered on, the slider 5-2 pulls the cutting wire 4, and the take-up wheel 6-2 releases the cutting wire 4. When the electromagnet 5-3 is powered off, the take-up wheel 6-2 reels the cutting wire 4 again under the action of the torsion spring. In this way, the cutting wire 4 can be controlled to move back and forth to saw the aerated brick blank; the frequency of the reciprocating movement of the cutting wire 4 can be controlled by controlling the frequency of the on and off of the electromagnet 5-3.

[0022] It should be noted that the speed at which the cutting frame 3 moves downward needs to be adapted to the sawing speed of the cutting wire 4, so as to avoid the cutting wire 4 being over-tightened and broken, or the cutting wire 4 being subjected to excessive force, resulting in the reel 6-2 being unable to reel in the cutting wire 4 under the action of the torsion spring; In order to avoid the situation that the cutting wire 4 is over-tightened, the slider 5-2 is connected to the cutting wire 4 via the tension sensor 5-6, that is, the tension of the cutting wire 4 can be monitored in real time through the tension sensor 5-6; during normal cutting operation, the tension of the cutting wire 4 is within the set threshold range. When the tension of the cutting wire 4 exceeds the set threshold range, it indicates that the cutting frame 3 moves down too fast, or the aerated brick blank contains foreign matter, and the cutting encounters resistance; when the tension of the cutting wire 4 is lower than the set threshold range, it indicates that the cutting wire 4 is broken, that is, the operating status of the cutting wire 4 can be judged by the tension value fed back by the tension sensor 5-6, so that the operator can make corresponding adjustments in time.
