Description

Technical Field

[0001] The invention relates to the technical field of aerated brick processing, and in particular to an aerated brick demoulding and cross-cutting device and a use method thereof. Background Art

[0002] Aerated bricks, that is, autoclaved aerated concrete bricks, are a new type of lightweight porous building material. They have the advantages of light weight, good thermal insulation, good sound insulation, and strong fire resistance. They are widely used in the construction field.

[0003] The processing of aerated bricks includes the steps of raw material preparation, casting, static stopping and cutting, autoclaving and curing. When cutting aerated bricks, cutting equipment is needed. In the related technology, for example, Chinese patent CN209812838U discloses an adjustable transverse cutting device for aerated bricks. When cutting the blank, the adjustable transverse cutting device for aerated bricks first tightens the steel wire to a certain degree by controlling the cylinder for trial cutting. If the steel wire is too loose during the trial cutting, the steel wire is further tightened by controlling the return stroke of the piston rod of the cylinder until the cutting requirement is met. If the steel wire breaks, it means that the steel wire is too tight. The piston rod of the control cylinder is extended to relax the steel wire until the steel wire no longer breaks during cutting and the cutting requirement is met. After adjusting the tightness of the steel wire, formal cutting and production are carried out.

[0004] Although the above-mentioned easy-to-adjust aerated brick transverse cutting device can realize automatic adjustment of the tightness of the steel wire, it is found in actual use that the steel wire always cuts the blank on the same side. This single-direction cutting method causes uneven wear of the steel wire, which seriously affects the utilization rate of the steel wire. At the same time, it increases the frequency of steel wire replacement and the maintenance cost of the equipment, which to a certain extent restricts the improvement of the production efficiency of aerated bricks. Summary of the invention

[0005] Based on this, it is necessary to provide an aerated brick demoulding and cross-cutting device and a method for using it to address the problem of low production efficiency in the current aerated brick production process.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A demoulding and cross-cutting device for aerated bricks, comprising:

[0008] A guide rail frame extends in a horizontal direction and is configured to place aerated brick bodies;

[0009] A cutting frame, which is arranged on the guide rail frame and can move relative to the aerated brick body along the extension direction of the guide rail frame;

[0010] The cutting wire is horizontally placed on the cutting frame and is configured to perform transverse cutting on the aerated brick body. The cutting wire can rotate around its own axis to switch the contact surface with the aerated brick body.

[0011] Furthermore, the aerated brick demoulding and cross-cutting equipment also includes an auxiliary wire and a connecting part, the auxiliary wire is horizontally placed on the cutting frame and is located on the same horizontal plane as the cutting wire; the connecting part is simultaneously sleeved on the cutting wire and the auxiliary wire, so that the cutting wire and the auxiliary wire both form a V-shaped structure, the opening of the V-shaped structure formed by the cutting wire faces the aerated brick body, and the opening of the V-shaped structure formed by the auxiliary wire faces away from the aerated brick body.

[0012] Furthermore, the diameter of the auxiliary wire is greater than the diameter of the cutting wire.

[0013] Furthermore, the surface roughness of the auxiliary wire is smaller than the surface roughness of the cutting wire.

[0014] Furthermore, the number of the cutting wires, the auxiliary wires and the connecting parts is equal, and there are multiple of each. One cutting wire, one auxiliary wire and one connecting part constitute a group of cutting components, and multiple groups of cutting components are arranged at intervals along the vertical direction.

[0015] Furthermore, the opening angle of the V-shaped structure formed by the cutting wire decreases from top to bottom along the vertical direction; the opening angle of the V-shaped structure formed by the auxiliary wire decreases from top to bottom along the vertical direction.

[0016] Furthermore, a plurality of groups of the cutting assemblies are arranged at intervals along the extension direction of the guide rail frame, and the cutting wire located at the top cuts the aerated brick body first.

[0017] Furthermore, the aerated brick demoulding and cross-cutting equipment also includes a driving member, and the driving member is configured to provide a driving force for the cutting wire to rotate.

[0018] Furthermore, the cutting frame can reciprocate along a horizontal direction perpendicular to the extending direction of the guide rail frame.

[0019] The present invention also provides a method for using an aerated brick demoulding and cross-cutting device, which uses an aerated brick demoulding and cross-cutting device. The method for using the aerated brick demoulding and cross-cutting device comprises the following steps:

[0020] S1. Place the aerated brick body on the guide rail frame;

[0021] S2, driving the cutting wire to rotate around its own axis;

[0022] S3, driving the cutting frame or the aerated brick body to move along the extension direction of the guide rail frame, so that the cutting frame and the aerated brick body are close to each other.

[0023] The beneficial effects of the present invention are:

[0024] The invention relates to an aerated brick demoulding and transverse cutting device and a use method thereof, wherein the use method of the aerated brick demoulding and transverse cutting device comprises using the aerated brick demoulding and transverse cutting device to cut an aerated brick blank; in the process of cutting the aerated brick blank, the aerated brick blank is first placed on a guide rail frame, and then the cutting wire is driven to rotate around its own axis, and then the cutting frame or the aerated brick blank is driven to move along the extension direction of the guide rail frame, so that the cutting frame and the aerated brick blank are close to each other, and then the aerated brick blank is transversely cut by the cutting wire; by setting the cutting wire to rotate around its own axis while cutting the aerated brick blank, the contact surface between the cutting wire and the aerated brick blank can be switched in real time, so that each part of the cutting wire can be in uniform contact with the aerated brick blank, and then the wear degree of each part of the cutting wire can be consistent, which is beneficial to improving the utilization rate of the cutting wire and helps to reduce the replacement frequency of the cutting wire, reduce the equipment downtime maintenance time, and improve the production efficiency of aerated bricks.

[0025] Furthermore, by providing an auxiliary wire and a connecting portion, the cutting wire and the auxiliary wire can both form a V-shaped structure, and the opening of the V-shaped structure formed by the cutting wire faces the aerated brick body, and the opening of the V-shaped structure formed by the auxiliary wire faces away from the aerated brick body, so that in the process of cutting the aerated brick body, when the cutting wire and the aerated brick body just start to contact, the V-shaped structure formed by the cutting wire can gradually cut the aerated brick body in a gradual manner, which is beneficial to reducing the cutting resistance. On the one hand, it helps to improve the smoothness of the cutting wire when cutting into the aerated brick body, and on the other hand, it helps to reduce the damage to the end face of the aerated brick body; when the cutting wire moves to the end section of the aerated brick body, the V-shaped structure formed by the cutting wire can gradually cut the aerated brick body in a gradual manner, which is beneficial to reducing the damage to the end face of the aerated brick body; at the same time, the V-shaped structure formed by the auxiliary wire can guide the debris in the cutting seam of the aerated brick body out, avoiding the debris from accumulating in the cutting seam of the aerated brick body for a long time, which affects the surface quality of the aerated brick body.

[0026] Furthermore, by setting the diameter of the auxiliary wire to be larger than the diameter of the cutting wire, during the process of cutting the aerated brick body, the auxiliary wire can support the upper layer of the aerated brick body, so that the gravity of the upper layer of the aerated brick body will not act on the cutting wire, thereby ensuring that the cutting resistance encountered by the cutting wire is always consistent, avoiding additional wear.

[0027] Furthermore, by setting the surface roughness of the auxiliary wire to be smaller than the surface roughness of the cutting wire, during use, the auxiliary wire has a relatively smooth surface, so that the damage to the surface of the aerated brick body can be minimized; and the cutting wire has a relatively rough surface, so that the cutting effect of the aerated brick body can be improved.

[0028] Furthermore, the opening angle of the V-shaped structure formed by the cutting wire is arranged to decrease successively from top to bottom in the vertical direction, and the opening angle of the V-shaped structure formed by the auxiliary wire is arranged to decrease successively from top to bottom in the vertical direction, so that during use, the V-shaped structure formed by the cutting wire and the auxiliary wire has a better supporting effect on the aerated brick body, so as to adapt to the situation where the weight of the aerated brick body that the cutting wire and the auxiliary wire need to bear becomes heavier as they go downwards.

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned herein, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0041] like Figures 1 to 7 As shown, the aerated brick demoulding and cross-cutting equipment provided in an embodiment of the present invention is used for cross-cutting aerated brick bodies 8, and is configured to include a guide frame 1, a cutting frame 2 and a cutting wire 3, wherein the guide frame 1 extends in a horizontal direction, and is configured to be able to place the aerated brick bodies 8; the cutting frame 2 is arranged on the guide frame 1, and can move relative to the aerated brick bodies 8 along the extension direction of the guide frame 1; the cutting wire 3 is horizontally placed on the cutting frame 2, and is configured to be able to perform transverse cutting on the aerated brick bodies 8, and the cutting wire 3 can rotate around its own axis to switch the contact surface between it and the aerated brick bodies 8.

[0042] Specifically in this embodiment, Figure 1As shown, the guide rail frame 1 and the cutting frame 2 are extended horizontally in the left-right direction as a whole; to facilitate the installation of the cutting frame 2, the guide rail frame 1 is configured to have two parallel first beams 101, the two first beams 101 are arranged at intervals in the front-to-back direction, the first beams 101 extend in the left-to-right direction, and the cutting frame 2 is simultaneously mounted on the two first beams 101 during installation.

[0043] To facilitate the installation of the cutting wire 3, Figure 2 As shown, the cutting frame 2 is configured to have two vertical beams 201, the two vertical beams 201 are arranged in parallel and spaced apart in the front-to-back direction, the vertical beams 201 extend in the up-down direction, the upper parts of the two vertical beams 201 are arranged at the lower part of the cutting frame 2, and the lower parts of the two vertical beams 201 are suspended. The two ends of the cutting wire 3 are respectively arranged on the lower inner surfaces of the two vertical beams 201 during installation, and the vertical surfaces where the two vertical beams 201 are located are perpendicular to the extension direction of the guide frame 1, so that the cutting wire 3 and the extension direction of the guide frame 1 are arranged perpendicularly, thereby enabling the cross-cutting of the aerated brick body 8 to be achieved.

[0044] To avoid interference between the vertical beam 201 and the aerated brick body 8, Figure 1 As shown, the two vertical beams 201 are respectively located outside the two first horizontal beams 101 , so that the aerated brick body 8 can only contact with the cutting wire 3 .

[0045] In order to ensure structural stability and facilitate the control of cutting accuracy, the aerated brick body 8 is configured to be able to move along the extension direction of the guide frame 1; specifically, by driving the aerated brick body 8 to move, the cutting wire 3 can be fixed in a relatively stable position, making the main structure of the entire cutting system more stable, because the fixation of the cutting wire 3 reduces the vibration source caused by too many moving parts. In contrast, if the cutting wire 3 is driven to move, the cutting wire 3 is prone to shaking during the movement, and it is difficult to ensure the accuracy of its movement trajectory, which in turn affects the cutting accuracy.

[0046] In order to facilitate the placement and movement of the aerated brick body 8, the guide rail frame 1 is configured to also have a vehicle body (not shown). The vehicle body is arranged between the two first beams 101 and can move along the extension direction of the guide rail frame 1. The aerated brick body 8 is placed on the top of the vehicle body during installation.

[0047] During use, the aerated brick body 8 is first placed on the top of the vehicle body; then the cutting wire 3 is driven to rotate around its own axis; then the vehicle body is started, and the vehicle body drives the aerated brick body 8 to move along the extension direction of the guide frame 1 and in the direction close to the cutting wire 3, and then the aerated brick body 8 is transversely cut by the cutting wire 3; by setting the cutting wire 3 to rotate around its own axis while cutting the aerated brick body 8, the contact surface between the cutting wire 3 and the aerated brick body 8 can be switched in real time, so that each part of the cutting wire 3 can be in uniform contact with the aerated brick body 8, and then the degree of wear of each part of the cutting wire 3 can be consistent, which is beneficial to improve the utilization rate of the cutting wire 3, while helping to reduce the replacement frequency of the cutting wire 3, reduce the equipment downtime maintenance time, and improve the production efficiency of aerated bricks.

[0048] In some embodiments, the demoulding and cross-cutting device for aerated bricks further includes a driving member, which is configured to provide a driving force for the cutting wire 3 to rotate.

[0049] Specifically in this embodiment, the driving member can be set as a first driving motor 6, such as Figure 2 As shown, the first drive motor 6 is arranged on the lower outer surface of the vertical beam 201, and the motor shaft of the first drive motor 6 extends in the front-to-back direction and points inward. The end of the cutting wire 3 is coaxially arranged on the motor shaft of the first drive motor 6 when installed.

[0050] More specifically, in order to improve the connection stability between the cutting wire 3 and the first driving motor 6, as Figure 7 As shown, a connecting sleeve 601 is coaxially sleeved on the motor shaft of the first drive motor 6. Since the connecting sleeve 601 and the motor shaft of the first drive motor 6 are coaxially connected, the stability and coaxiality of power transmission can be guaranteed, and the vibration and energy loss caused by the misalignment can be reduced, thereby ensuring that the power can be smoothly transmitted to subsequent components; a columnar groove is coaxially opened at the end of the connecting sleeve 601 away from the first drive motor 6, and a fixing sleeve 602 is inserted in the columnar groove. When installing, the end of the cutting wire 3 is coaxially inserted in the fixing sleeve 602. The fixing sleeve 602 plays a role in connecting the cutting wire 3 and the connecting sleeve 601. It can better fix the cutting wire 3 and prevent the cutting wire 3 from loosening or deflecting due to factors such as force during operation, thereby improving the connection stability between the cutting wire 3 and the first drive motor 6.

[0051] More specifically, in order to improve the stability of the connecting sleeve 601 during rotation, two bearings 603 are inserted into the vertical beam 201 of the cutting frame 2, and the two bearings 603 are respectively sleeved on the two ends of the connecting sleeve 601.

[0052] During use, the first drive motor 6 is started, and the first drive motor 6 drives the cutting wire 3 to rotate to switch the contact surface between the cutting wire 3 and the aerated brick body 8.

[0053] In other embodiments, when the cutting wire 3 cuts the aerated brick body 8, on the one hand, since the cutting wire 3 cuts the aerated brick body 8 in a manner that the cutting wire 3 contacts the aerated brick body 8 as a whole at the same time, in this cutting method, during the initial cutting period, the cutting wire 3 needs to withstand a strong resistance from the aerated brick body 8; similarly, at the end of the cutting, the cutting wire 3 will also be subjected to a large stress impact in order to complete the final cutting action. The continuous high stress will undoubtedly accelerate the wear of the cutting wire 3 and greatly shorten its life. At the same time, the aerated brick body 8 is also subjected to a large reaction force from the cutting wire 3, and the texture of the aerated brick body 8 itself is not uniform. At the edges, corners and other parts, due to stress concentration, it is very easy to cause collapse, which affects the molding quality of the aerated brick.

[0054] On the other hand, during the cutting process, a large amount of debris cut from the aerated brick body 8 will accumulate in the cutting seam. As the cutting continues, these debris continue to accumulate, which will not only significantly increase the resistance of the subsequent cutting of the cutting wire 3, causing the cutting process to become stuck and affecting the cutting efficiency, but also after the cutting is completed, these debris will remain on the cutting seam surface of the aerated brick body 8, greatly affecting the surface flatness and smoothness of the aerated brick body 8. In order to solve these two problems, the aerated brick demoulding and cross-cutting equipment is configured to also include an auxiliary wire 4 and a connecting part 5, the auxiliary wire 4 is horizontally placed on the cutting frame 2, and is located on the same horizontal plane as the cutting wire 3; the connecting part 5 is simultaneously sleeved on the cutting wire 3 and the auxiliary wire 4, so that the cutting wire 3 and the auxiliary wire 4 both form a V-shaped structure, the opening of the V-shaped structure formed by the cutting wire 3 faces the aerated brick body 8, and the opening of the V-shaped structure formed by the auxiliary wire 4 faces away from the aerated brick body 8.

[0055] Specifically in this embodiment, Figure 2 As shown, the two ends of the auxiliary wire 4 are respectively arranged on the lower inner surface of the two vertical beams 201 during installation, and are located on the left side of the cutting wire 3, so that the cutting wire 3 can contact the aerated brick body 8 first.

[0056] like Figure 6 As shown, the connecting portion 5 is arranged as an "I"-shaped structure and has two end rods respectively located on both sides. When installed, the middle part of the auxiliary wire 4 passes through the end rod on the right side and is fixedly connected to the end rod so that the connecting portion 5 has a determined position; the cutting wire 3 is divided into two sections, and the inner end portions of the two sections of the cutting wire 3 are respectively rotated and inserted into the two ends of the end rod on the left side, and the distance between the two end rods is smaller than the distance between the cutting wire 3 and the auxiliary wire 4, so that the middle part of the auxiliary wire 4 can be concave to the left under the pulling of the right end rod to form a V-shaped structure opening to the right, and the middle part of the cutting wire 3 can be concave to the right under the pulling of the left end rod to form a V-shaped structure opening to the left.

[0057] It is understandable that when the cutting wire 3 is divided into two sections, in order to simultaneously drive the two sections of the cutting wire 3 to rotate around their own axes, two first drive motors 6 are provided and are respectively arranged on the lower outer walls of the two vertical beams 201.

[0058] During the cutting process of the aerated brick body 8, when the cutting wire 3 first contacts the aerated brick body 8, since the V-shaped structure formed by the cutting wire 3 opens toward the aerated brick body 8, at the initial contact moment, the cutting wire 3 does not bear the strong resistance of the aerated brick body 8 as a whole at the same time as in the traditional cutting method, but cuts in gradually.

[0059] This gradual cutting method greatly reduces the resistance encountered during the initial cutting. Compared with the traditional overall simultaneous contact cutting, the V-shaped structure of the cutting wire 3 can start from both ends and penetrate into the interior of the aerated brick body 8 little by little. This not only helps to improve the smoothness of the cutting wire 3 when cutting into the aerated brick body 8, but also avoids the jamming phenomenon caused by instantaneous excessive resistance, so that the cutting action can be carried out smoothly and smoothly; on the other hand, it also greatly reduces the risk of damage to the end face of the aerated brick body 8.

[0060] When the cutting wire 3 moves to the end of the aerated brick body 8 and is about to complete the cutting action, the cutting wire 3 gradually performs the final cutting operation on the aerated brick body 8 in a gradual manner. In this process, the V-shaped structure enables the cutting wire 3 to steadily reduce the force on the remaining part when it leaves the aerated brick body 8, further reducing the damage to the end face of the aerated brick body 8, and avoiding the edge of the aerated brick body 8 from breaking or becoming uneven due to the sudden withdrawal of the cutting wire 3, thereby ensuring the molding quality of the aerated brick.

[0061] At the same time, since the tip of the V-shaped structure formed by the auxiliary wire 4 is facing the aerated brick body 8, with the relative movement between the auxiliary wire 4 and the aerated brick body 8, the debris can be moved out of the cutting seam of the aerated brick body 8 from the inside to the outside under the guidance of the V-shaped structure formed by the auxiliary wire 4, thereby avoiding the debris from accumulating in the cutting seam of the aerated brick body 8 for a long time, effectively preventing the problems of increased cutting resistance and reduced cutting efficiency caused by the accumulation of debris, and more importantly, ensuring the surface flatness and smoothness of the aerated brick body 8 after cutting.

[0062] In a further embodiment, as the cutting wire 3 continues to cut the aerated brick body 8, when part of the aerated brick body 8 is cut, its own weight will inevitably press on the cutting wire 3, thereby increasing the resistance encountered by the cutting wire 3 in the subsequent cutting action, causing the cutting wire 3 to not only overcome the internal structural resistance of the uncut part of the aerated brick body 8 when moving, but also to additionally withstand the friction force converted from the pressure of the cut part. This additional resistance significantly increases the load borne by the cutting wire 3 per unit time; under this high-load working state, the wear rate of the cutting wire 3 will accelerate sharply, thereby affecting its service life. To solve this problem, the diameter of the auxiliary wire 4 is set to be larger than the diameter of the cutting wire 3.

[0063] During use, after the cutting wire 3 completes cutting of a certain part of the aerated brick body 8, the upper layer of the cut aerated brick body 8 begins to face a change in the direction of gravity. At this time, the auxiliary wire 4 with a larger diameter first contacts this part of the aerated brick body 8 and supports it, so that the gravity of the upper aerated brick body 8 cannot directly act on the cutting wire 3, thereby simplifying the resistance structure encountered by the cutting wire 3 in the subsequent cutting process, and always maintains a state where it only needs to overcome the internal structural resistance of the uncut part of the aerated brick body 8, thereby ensuring that the cutting resistance borne by the cutting wire 3 during the entire cutting operation is always maintained at a stable and consistent level, avoiding additional wear caused by the intervention of the gravity of the upper aerated brick body 8.

[0064] In other embodiments, when the cutting wire 3 cuts the aerated brick body 8, the cutting wire 3 and the auxiliary wire 4 simultaneously move relative to the aerated brick body 8, so that the cutting wire 3 and the auxiliary wire 4 will both generate friction with the aerated brick body 8, wherein the friction between the cutting wire 3 and the aerated brick body 8 can ensure the cutting effect, while the friction between the auxiliary wire 4 and the aerated brick body 8 will destroy the surface structure of the aerated brick body 8. In order to ensure the cutting effect of the cutting wire 3 and avoid the auxiliary wire 4 from excessively damaging the surface quality of the aerated brick body 8, the surface roughness of the auxiliary wire 4 is set to be less than the surface roughness of the cutting wire 3.

[0065] During use, when the auxiliary wire 4 contacts the aerated brick body 8 with a smaller surface roughness and generates relative movement, the friction between it and the aerated brick body 8 is significantly reduced. Under the premise that the auxiliary wire 4 can support the aerated brick body 8 and clean up the debris in the cutting seam of the aerated brick body 8, the adverse effects on the surface of the aerated brick body 8 are minimized. Compared with the case of larger surface roughness, the auxiliary wire 4 can interact with the aerated brick body 8 in a gentler way, thereby effectively avoiding surface damage of the aerated brick body 8 caused by excessive friction, ensuring that the aerated brick body 8 can still maintain good surface quality after cutting, laying a solid foundation for subsequent processing and use; and the cutting wire 3 contacts the aerated brick body 8 with a larger surface roughness and generates a relative moving surface, which can improve the cutting effect of the aerated brick body 8.

[0066] In other embodiments, in the actual production process of aerated bricks, the aerated brick body 8 is usually large in size due to the requirements of application scenarios. In order to adapt to various building usage specifications, it is often necessary to cut it into multiple layers. To meet this requirement, the number of cutting wires 3, auxiliary wires 4 and connecting parts 5 is equal, and there are multiple of them. One cutting wire 3, one auxiliary wire 4 and one connecting part 5 constitute a group of cutting components, and multiple groups of cutting components are arranged at intervals in the vertical direction.

[0067] Specifically in this embodiment, taking the example that the aerated brick body 8 needs to be cut into seven layers at equal intervals, the number of cutting assemblies is set to six, and they are arranged on two vertical beams 201 at equal intervals along the vertical direction.

[0068] In a further embodiment, in the process of the aerated brick body 8 being divided into multiple layers, from top to bottom, the weight of the auxiliary wire 4 from the aerated brick body 8 that has been cut will be superimposed, and the auxiliary wire 4 has an upper limit on the pressure that can be borne when the opening of the V-shaped structure remains unchanged, resulting in the auxiliary wire 4 having a worse supporting effect the closer it is to the bottom. To solve this problem, the opening angle of the V-shaped structure formed by the cutting wire 3 decreases in the vertical direction from top to bottom; the opening angle of the V-shaped structure formed by the auxiliary wire 4 decreases in the vertical direction from top to bottom.

[0069] Specifically in this embodiment, from the perspective of mechanical principles, a smaller opening angle can distribute the weight of the aerated brick body 8 more evenly to the cutting wire 3 and the auxiliary wire 4, effectively increasing the stability of the support. Compared with the case of a larger opening angle, a smaller opening angle increases the contact area between the cutting wire 3 and the auxiliary wire 4 and the aerated brick body 8, thereby improving the bearing capacity per unit area. This is like a stable triangular support structure. The narrower the bottom edge, the more concentrated and stable the distribution of the supporting force for the object above, thereby being able to adapt to the actual situation that the weight of the aerated brick body 8 that the cutting wire 3 and the auxiliary wire 4 need to bear becomes heavier as they go down.

[0070] In other embodiments, during the process of the aerated brick body 8 being divided into multiple layers, when multiple cutting assemblies simultaneously cut the aerated brick body 8, the cutting forces between the cutting assemblies will affect each other, making it difficult to achieve precise control. At the same time, the cutting stresses borne by different parts of the aerated brick body 8 become complex and unbalanced, which may not only lead to deviations in the dimensional accuracy of the aerated bricks after cutting and affect product quality, but may also cause unnecessary displacement or deformation of the aerated brick body 8 during the cutting process, increasing the scrap rate and reducing production efficiency. When multiple cutting assemblies cut the aerated brick body 8 from bottom to top in sequence, The upper aerated brick body 8 becomes unstable due to the vibration caused by the cutting below, and the impact force generated when cutting below will be transmitted upward along the aerated brick body 8, causing the upper part that has not been cut to shake. This is undoubtedly a huge interference for high-precision cutting operations, and as the number of cutting layers increases, the cumulative effect of this vibration and shaking becomes more and more obvious, which will seriously affect the cutting accuracy and the overall quality of the aerated brick. To solve this problem, multiple groups of cutting components are arranged at intervals along the extension direction of the guide rail frame 1, and the cutting wire 3 at the top cuts the aerated brick body 8 first.

[0071] Specifically in this embodiment, it is taken as an example that the aerated brick body 8 needs to be cut into seven layers at equal intervals. Figure 2 As shown, the six cutting assemblies are divided into four columns, and the two middle columns each contain two cutting assemblies, among which the cutting assembly on the far right has the highest vertical height, the two cutting assemblies in the second column from right to left have decreasing vertical heights, the two cutting assemblies in the third column from right to left have decreasing vertical heights again, and the cutting assembly on the far left has the lowest vertical height.

[0072] To facilitate installation of six cutting components, such as Figure 2 As shown, there are eight vertical beams 201, which are evenly divided into four groups. The four groups of vertical beams 201 are arranged at intervals along the left and right directions. Four columns of cutting components and four groups of vertical beams 201 are correspondingly arranged, and the lengths of the four groups of vertical beams 201 decrease from right to left to adapt to the height requirements of the cutting components in the vertical direction.

[0073] When in use, the rightmost cutting assembly is used to cut the aerated brick body 8 first, and then the two cutting assemblies in the second column from right to left cut the aerated brick body 8, and then the two cutting assemblies in the third column from right to left cut the aerated brick body 8, and the leftmost cutting assembly cuts the aerated brick body 8 last. This arrangement of the cutting sequence fully considers the overall stability of the aerated brick body 8. Cutting from the top can allow the aerated brick body 8 to be gradually divided in a relatively stable state. As the cutting proceeds downward, the cut part above will not be affected by the vibration of the cutting below, reducing the risk of the overall shaking of the aerated brick body 8. Moreover, the cutting sequence from top to bottom conforms to the principle of gravity, making the cutting process smoother and more natural, and further improving the cutting efficiency and product quality. In this way, the problems that arise when multiple groups of cutting assemblies are cutting at the same time or from bottom to top are effectively overcome.

[0074] In other embodiments, in the traditional cutting method of aerated brick blank 8, the cutting wire 3 often cuts the aerated brick blank 8 at a relatively fixed position, which limits the cutting speed to a certain extent, thereby affecting the production efficiency of aerated bricks. To solve this problem, the cutting frame 2 is configured to be able to reciprocate in a horizontal direction perpendicular to the extension direction of the guide rail frame 1.

[0075] Specifically in this embodiment, the cutting frame 2 drives the cutting wire 3 to move synchronously when it moves. This movement mode simulates the working form of a traditional cutting saw. On the one hand, from the perspective of cutting speed, the cutting frame 2 drives the cutting wire 3 to move back and forth, so that the process of the cutting wire 3 cutting into the aerated brick body 8 is no longer a slow advancement, but a high-frequency "rapid cutting to exiting to re-cutting" cycle, thereby improving the cutting efficiency; on the other hand, from the perspective of cutting uniformity, this reciprocating cutting form also helps to ensure cutting uniformity, because the cutting wire 3 can act on the same part of the aerated brick body 8 multiple times during the reciprocating process, thereby avoiding the problem of uneven cutting surface caused by uneven single cutting force.

[0076] In order to realize that the cutting frame 2 can reciprocate in a horizontal direction perpendicular to the extension direction of the guide frame 1, the aerated brick demoulding and cross-cutting device is configured to further include a transmission assembly 7, and the transmission assembly 7 can be configured to include a second drive motor 701, a first connecting rod 702 and a second connecting rod 703, such as Figure 2 and Figure 3 As shown, the second drive motor 701 is installed on the cutting frame 2; one end of the first connecting rod 702 is rotatably sleeved on the motor shaft of the second drive motor 701, and the other end is hinged to the end of the second connecting rod 703, and the other end of the second connecting rod 703 is hinged to the cutting frame 2.

[0077] In order to facilitate the installation of the second drive motor 701 , a crossbar is placed between the two first crossbeams 101 , and the second drive motor 701 is arranged at the bottom of the crossbar during installation.

[0078] In order to facilitate the cutting frame 2 to be driven and moved by the second connecting rod 703, Figure 2 As shown, the cutting frame 2 is configured to also have four second cross beams 202, the four second cross beams 202 are arranged at intervals in the left-right direction, the second cross beams 202 extend in the front-to-back direction, and the second connecting rod 703 is hinged at one end away from the first connecting rod 702 when installed to the bottom of the second second cross beam 202 from the right to the left; to facilitate the connection between the second cross beam 202 and the vertical beam 201, the cutting frame 2 is configured to also have two third cross beams 203, the two third cross beams 203 are arranged at intervals in the front-to-back direction, the third cross beam 203 extends in the left-to-right direction, the second cross beam 202 is located between the two third cross beams 203, the two ends of the second cross beam 202 are respectively vertically connected to the two third cross beams 203, and the upper end of the vertical beam 201 is vertically connected to the bottom of the third cross beam 203.

[0079] In order to facilitate the sliding connection between the cutting frame 2 and the guide frame 1, as shown in FIG. Figure 1 As shown, sliding sleeves 204 are slidably connected at both ends of each second crossbeam 202, and the sliding sleeves 204 extend in the front-to-back direction. The two sliding sleeves 204 on the same second crossbeam 202 are respectively fixedly connected to the tops of the two first crossbeams 101, so that the guide cutting frame 2 can only move in the horizontal direction perpendicular to the extension direction of the guide rail frame 1.

[0080] During use, the second drive motor 701 is started, and the second drive motor 701 drives the first connecting rod 702 to rotate around the axis of the motor shaft of the second drive motor 701. The first connecting rod 702 synchronously drives the second connecting rod 703 to move, so as to drive the cutting frame 2 to reciprocate in a horizontal direction perpendicular to the extension direction of the guide frame 1.

[0081] In other embodiments, the transmission assembly 7 may also be configured to include two drive cylinders, which are respectively fixedly connected to the tops of the two first beams 101 , and the output shafts of the drive cylinders extend along the extension direction of the first beam 101 and are vertically fixedly connected to the second beam 202 .

[0082] It can be understood that the driving cylinder can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0083] During use, the drive cylinder is started, and the output shaft of the drive cylinder is continuously extended or retracted, synchronously driving the cutting frame 2 to reciprocate along a horizontal direction perpendicular to the extension direction of the guide frame 1.

[0084] In other embodiments, the cutting wire 3 and / or the auxiliary wire 4 can be set as steel wire to reduce the use cost.

[0085] In other embodiments, the cutting wire 3 and / or the auxiliary wire 4 may also be configured as carbon fiber wire, diamond wire or ceramic fiber wire.
