Description

Technical Field

[0001] This invention belongs to the field of sintered brick production technology, and relates to an adjustable brick blank cutting system and method. Background Technology

[0002] Bricks are small, man-made building blocks, classified into sintered bricks (mainly clay bricks) and non-sintered bricks (such as sand-lime bricks and fly ash bricks), commonly known as bricks. Currently, the production process for commonly used sintered bricks typically involves first crushing and screening the raw materials, then introducing the qualified materials into an aging chamber for aging; next, further crushing and reducing the particle size, mixing the qualified particles with water (or omitting water if the raw materials have a high moisture content), then extruding and cutting the mixture to obtain long strips (hereinafter referred to as blanks); then cutting the strips to obtain brick blanks, and finally firing and cooling the brick blanks to obtain hard, shape-stable bricks.

[0003] When cutting the billet strip, there is a reciprocating pusher plate at the upstream end and multiple evenly distributed wires made of steel, iron, or other materials (hereinafter collectively referred to as cutting wires) at the downstream end. The pusher plate pushes the billet strip downstream, and the strip is cut as it passes the cutting wires, thus obtaining brick blanks of the required size. The cutting wires are consumables and need to be replaced periodically. For easy replacement, both ends of the cutting wires have connecting rings. Below the cutting unit are multiple bent hooks, and above are multiple fixed arms and swing arms hinged to the fixed arms. Each hook corresponds to a fixed arm and a swing arm. The fixed arms are in a fixed position, and there is a tension spring between the fixed arm and the swing arm to pull the swing arm upward. There is also a hook below the fixed arm. When replacing the cutting wire, the swing arm needs to be pressed down so that the connecting rings at both ends of the cutting wire can be removed from the two hooks. When installing the cutting wire, the free end of the swing arm also needs to be pressed down, and then both ends of the cutting wire are hooked onto the hooks. After releasing the swing arm, the cutting wire is positioned. In actual production, in order to ensure that the cutting wire has sufficient tension, the tension spring usually generates a large force. Therefore, the worker needs to exert a large force to move the swing arm to a position where the cutting wire can be removed or installed, which is quite strenuous. Summary of the Invention

[0032] The drive frame is provided in two horizontally arranged components, and the top of the drive frame is provided with a dovetail groove or a drive groove with an inverted T-shaped longitudinal section.

[0033] Each drive slot is movably provided with a drive bar that cooperates with the drive slot, and the pusher plate is fixedly connected to two drive bars;

[0034] A first drive arm and a second drive arm hinged to one end of the first drive arm, wherein the length of the first drive arm is more than twice the length of the second drive arm, and the end of the first drive arm away from the second drive arm is hinged to the middle of the side of the pusher plate opposite to the cutting wire.

[0035] A drive motor, the output shaft of which is connected to the free end of the second drive arm.

[0036] The present invention also discloses a method based on an adjustable brick blank cutting system as described in any of the preceding claims, comprising the following steps:

[0037] S1, during cutting, the terminating part abuts against the lower side of the swing arm, ensuring the position of the swing arm and preventing the connecting ring at the top of the cutting wire from separating from the first positioning hook;

[0038] S2, when changing the cutting wire, the second drive mechanism lowers the height of the termination part until it separates from the swing arm. At this time, the first elastic element maintains the angle and position of the swing arm.

[0039] S3, the worker manually presses down on the free end of the swing arm, causing the top connecting ring to separate from the first positioning hook and the bottom connecting ring to separate from the second positioning hook;

[0040] S4. After removing all the cutting wires, install new cutting wires. When installing, first put the bottom connecting ring on the second positioning hook, then press down on the free end of the swing arm and put the top connecting ring on the first positioning hook.

[0041] S5, after the swing arm is released, the first elastic element causes the swing arm to swing upward and prevents the connecting ring from separating from the first positioning hook and the second positioning hook;

[0042] S6, after all the cutting wires are installed, the second drive mechanism raises the stop member so that the top of the stop member abuts against the underside of all the swing arms.

[0043] Compared with the prior art, the present invention provides an adjustable brick blank cutting system and method. During the cutting of the blank strip, the termination element abuts against the lower side of the swing arm, ensuring the position of the swing arm and preventing the connecting ring at the top of the cutting wire from separating from the first positioning hook. When changing the cutting wire, the second drive mechanism lowers the height of the termination element until it separates from the swing arm. At this time, the first elastic element maintains the angle and position of the swing arm. The worker manually presses down on the free end of the swing arm, causing the top connecting ring to separate from the first positioning hook and the bottom connecting ring to separate from the second positioning hook. After all the cutting wires are removed, a new cutting wire is installed. During installation, the bottom connecting ring is first fitted onto the second positioning hook, and then the free end of the swing arm is pressed down to fit the top connecting ring onto the first positioning hook. After releasing the swing arm, the first elastic element causes the swing arm to swing upwards, preventing the connecting ring from separating from the first and second positioning hooks. After all the cutting wires are installed, the second drive mechanism raises the termination element, causing the top of the termination element to abut against the lower side of all the swing arms.

[0044] In this application, when the billet passes the cutting wire, the force exerted by the billet on the cutting wire is directly transmitted to the first support roller through the termination element. This means the first elastic element does not need to bear a large force or have a large tensile strength, allowing the worker to press down more easily when removing and installing the cutting wire. In other words, the first elastic element only temporarily pulls the swing arm before the cutting wire is fully fixed, thus requiring very little tensile force. However, current tension springs on the market need to withstand the force borne by the entire cutting wire and cannot swing excessively (to prevent brick deformation). Therefore, existing tension springs require the worker to apply a large or even very large force to drive the swing arm. In contrast, the force required to the swing arm in this application is smaller, and given the large number of swing arms, the structure of this application significantly improves operational convenience and labor-saving compared to existing swing arm and tension spring structures.

[0045] It should also be understood that although the length of the swing arm can be increased to a certain extent on the market, so that the swing arm can swing downwards relatively easily, the large density and number of swing arms, and the separation and splicing of the cutting wire are all carried out below the swing arm, make the actual operation more difficult and less convenient.

After all the cutting wires 14 are removed, a new cutting wire 14 is installed. During installation, the bottom connecting ring 15 is first sleeved on the second positioning hook 13, and then the free end of the swing arm 10 is pressed down to sleeve the top connecting ring 15 on the first positioning hook 12. After the swing arm 10 is released, the first elastic element 11 causes the swing arm 10 to swing upward and prevents the connecting ring 15 from separating from the first positioning hook 12 and the second positioning hook 13. After all the cutting wires 14 are installed, the second drive mechanism raises the termination piece 16 so that the top of the termination piece 16 abuts against the lower side of all the swing arms 10.

[0100] In this application, when the billet passes through the cutting wire 14, the force exerted by the billet on the cutting wire 14 is directly transmitted to the first support roller 6 through the termination member 16. This means the first elastic member 11 does not need to bear a large force or have a large tensile strength, allowing the worker to press down more easily when removing and installing the cutting wire 14. In other words, the function of the first elastic member 11 is only to temporarily pull the swing arm 10 before the cutting wire 14 is fully fixed, thus requiring very little tensile force. However, current tension springs on the market need to withstand the force borne by the entire cutting wire 14 and cannot swing excessively (to prevent brick deformation). Therefore, existing tension springs require the worker to apply a large or even very large force to drive the swing arm to swing. In contrast, the force required to be applied to the swing arm 10 in this application is smaller, and the number of swing arms 10 is also large. Therefore, compared to the existing structures of swing arms and tension springs, the structure of this application can greatly improve operational convenience and labor-saving.

[0101] It should also be understood that although the length of the swing arm can be increased to a certain extent on the market, so that the swing arm can swing downwards relatively easily, the swing arm has a high density and a large number of swing arms. Since the separation and splicing of the cutting wire 14 are all carried out below the swing arm, an excessively long swing arm will make the actual operation more difficult and less convenient.

[0102] During actual cutting, the billet is fed to the designated position by the feeding roller 2 and then stops. The drive motor 50 then drives the second drive arm 49 and the first drive arm 48 to move, simultaneously driving the pusher plate 3 forward and pushing the billet past all the cutting wires 14. When the billet moves forward, a portion of the previous billet is not yet cut, requiring the current billet to push it; similarly, the current billet is not completely cut by the cutting wires 14, but waits for the next billet to push it, thus eliminating the need for the pusher plate 3 to act on the cutting wires 14. Downstream of the cutting wires 14 is a conveyor belt used to receive and transport the cut bricks, allowing for a continuous supply of subsequent bricks to be cut.

[0103] During the cutting process, the cutting wire 14 located between the anti-detachment wheel 29 and the second positioning hook 13 cuts the blank. This part of the cutting wire 14 is inclined, so that the blank can be cut gradually, making the cutting smoother and reducing the vibration of the cutting wire 14 (the cutting wire 14 is not completely taut), thus ensuring the quality of the cutting.

[0104] When the gas cutting wire needs to be replaced, the adjusting screw 20 is rotated manually (with a large handwheel) or by motor drive, which simultaneously drives the two lifting parts 21 to move outward. During the movement of the lifting parts 21, the terminating part 16 moves downward under the pressure of gravity and the thrust of the second elastic part 19 until the height of the terminating part 16 reaches the set height. At this time, the position of the swing arm 10 does not change.

[0105] Then the worker can easily press down on the swing arm 10 to remove the top connecting ring 15 from the first positioning hook 12. After the middle of the cutting wire 14 is wrapped around the anti-detachment wheel 29, the bottom connecting ring 15 can be removed from the second positioning hook 13. This operation is repeated until all the cutting wires 14 are removed.

[0106] When installing a new cutting wire 14, first attach the bottom connecting ring 15 to the second positioning hook 13, then pass the middle of the cutting wire 14 around the anti-detachment wheel 29, press down on the swing arm 10, and attach the top connecting ring 15 to the first positioning hook 12. After releasing the swing arm 10, the first elastic element 11 causes the swing arm 10 to move upward and temporarily maintains the position of the cutting wire 14 (the tension applied to the cutting wire 14 by the first elastic element 11 is very small). After all the cutting wires 14 are installed, rotate the adjusting screw 20 to bring the two lifting elements 21 closer together and raise the height of the termination element 16 until the top of a certain lifting element 21 touches the lower side of all the swing arms 10, or is slightly lower than the lower side of the swing arms 10, thus completing the positioning of the cutting wire 14. Subsequently, even if the swing arm 10 has a downward swinging tendency during cutting, the termination element 16 also prevents the swing arm 10 from swinging, thus allowing for stable cutting. Since the termination piece 16 can release the limit on all swing arms 10 at once, and can complete the limit on all swing arms 10 in one operation, the operation is convenient and efficient, and the operation is more labor-saving overall.

[0107] In actual production, not all bricks have a fixed width, especially custom-made or non-standard bricks, which require adjustment of the positions of the first positioning hook 12 and the second positioning hook 13. It is preferable to adjust the position without the cutting wire 14, i.e., after the positions of the first sliding member 24 and the second sliding member 25 have been adjusted, the cutting wire 14 is installed. The adjustment of the positions of the first sliding member 24 and the second sliding member 25 is the same; this embodiment uses the adjustment of the first sliding member 24 as an example. During adjustment, simply rotate the adjusting rod 41 (either manually by turning the handwheel or using a motor). The adjusting rod 41 drives the two worm gear parts 42 to rotate, simultaneously rotating the two turbine parts 44, the two transmission columns 43, and the two gear parts 45. At the same time, the two adjusting racks 37 on both sides are also driven to rise or fall. During the lifting and lowering process, the stabilizing plates 36 on both sides of the positioning plate 35 abut against the positioning frame 32 through the first drag-reducing component (roller or ball), and the two sides of the adjusting rack 37 abut against the inner wall of the receiving groove 33 through the second drag-reducing component (roller or ball). This allows the positioning plate 35 to lift and lower stably with less resistance.

[0108] During the lifting and lowering process of the positioning plate 35, the position of the central linkage column 31 (the number of first sliding members 24 and second sliding members 25 is odd) remains unchanged, and it moves within the central positioning groove 38. However, the linkage columns 31 on both sides are driven by the inner wall of the side positioning groove 39, and therefore move outward respectively. At the same time, the inclination degree or angle of the different side positioning grooves 39 on the same side (the shape of each side positioning groove 39 needs to be calculated and designed separately) is different, so the movement speed and distance of the different first sliding members 24 are different. However, at any node, the distance between any two adjacent linkage columns 31 is equal. This ensures that after adjustment, the distance between any two adjacent first positioning hooks 12 is equal, and that the final cutting wire 14 will not tilt, thus ensuring the cutting quality.

[0109] Since the positions of all the first sliding members 24 and the second sliding members 25 can be adjusted simply by rotating the adjusting column, the adjustment efficiency is higher, and the quality of adjustment is guaranteed because the shapes of the positioning grooves are pre-designed. The first anti-rotation part 26 on the inner wall of the first sliding member 24 prevents it from rotating relative to the first support roller 6, and the second anti-rotation part 27 on the inner wall of the second sliding member 25 prevents it from rotating relative to the second support roller 8. At the same time, the first anti-rotation part 26 is rotatably connected to the first sliding member 24, and the second anti-rotation part 27 is rotatably connected to the second sliding part, thereby reducing the moving resistance of the first sliding member 24 and the second sliding member 25 and reducing the difficulty of operation.

[0110] In another embodiment, an outer end frame is provided between the outer ends of the two positioning frames 32, and a lead screw is vertically rotatably mounted in the middle of the outer end frame. A lead screw seat is also provided on the outer side of the positioning plate 35, and the lead screw is threadedly engaged with the lead screw seat. Thus, rotating the lead screw (manually or electrically) can drive the positioning plate 35 to rise and fall.

[0111] Moreover, once the position of the positioning plate 35 is adjusted, the turbine part 44 and the worm gear part 42 can also play a self-locking role, which ensures that the positioning plate 35 can maintain its position stability during subsequent use, and also ensures the stability of cutting and production.

[0112] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0113] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
