Abstract
Description
Technical Field
[0001] This utility model relates to the field of brick cutting technology, specifically to an adjustable brick cutting device. Background Technology
[0002] Porous sintered bricks are load-bearing building bricks with rectangular holes and a porosity of ≥28%, made from clay, shale, coal gangue, fly ash or solid waste as the main raw materials and fired at high temperature. In the production of porous sintered bricks, brick cutting equipment is usually used to cut the porous sintered brick blanks into bricks of the corresponding size.
[0003] According to the Chinese patent "An Automatic Cutting Device for Sintered Porous Brick Production" (authorization announcement number CN217861936U), the device uses a combination of mounting groove, telescopic rod, spring, and locking ball with the groove to position the adjusted cutting string and adjust the length of the cutting string according to the width of the brick blank, thus facilitating the adjustment of the brick blank cutting size according to production needs.
[0004] In the aforementioned application, the cutting string is subjected to vibration force transmitted to the surface of the spring and telescopic rod during the slitting of the brick blank. This can easily cause the spring to stretch or contract, which in turn leads to unstable positioning of the cutting string, thus affecting the slitting effect on the porous brick blank.
[0005] Based on this, the present invention designs an adjustable brick cutting device to solve the above problems. Utility Model Content
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable brick cutting device.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An adjustable brick cutting device includes a cutting table, with electric push rods fixedly connected to both sides of the inner wall of the cutting table, and an anti-loosening mechanism. The anti-loosening mechanism includes an adjusting frame fixedly connected to the telescopic end of the electric push rods. Several mounting brackets are slidably connected to the inner wall of the adjusting frame. A cutting chord is fixedly connected to the surface of the mounting bracket. An iron frame is fixedly connected to the front end of the adjusting frame. A screw is fixedly connected to the front end of the mounting bracket. A nut is threaded onto the surface of the screw. A magnetic ring is fixedly connected to the surface of the nut. One end of the magnetic ring is magnetically attracted to the front end of the iron frame.
[0009] Furthermore, a limiting frame is slidably connected to the inner wall of the iron frame, and the rear end of the limiting frame contacts one end of the magnetic ring.
[0010] Furthermore, a spring is fixedly connected to the end of the limiting frame, and the top end of the spring is fixedly connected to the inner top wall of the iron frame.
[0011] Furthermore, the end of the adjustment frame is provided with scale lines, and a transparent block is fixedly connected to the front end of the mounting bracket.
[0012] Furthermore, two actuating levers are fixedly connected to the surface of the nut.
[0013] Furthermore, a locking block is slidably connected to the upper end of the inner wall of the iron frame, and the surface of the locking block is slidably connected to the inner wall of the limiting frame.
[0014] Furthermore, a limiting hole is provided at the front end of the card block, and the inner wall of the limiting hole is slidably connected to the upper end of the inner wall of the iron frame.
[0015] Furthermore, the surface of the transparent block is triangular, and the transparent block is a transparent acrylic block component.
[0016] Beneficial effects
[0017] 1. The mounting frame and the adjustment frame work together to make it easy to precisely adjust the spacing of each cutting chord according to the width of the porous sintered brick blank. The iron frame, screw, nut and magnetic ring work together to lock the adjusted mounting frame, thereby ensuring the stability of the multiple cutting chord positions after adjustment and avoiding displacement of the cutting chords during cutting, thus ensuring the cutting effect of the porous sintered brick blank.
[0018] 2. By using the limit frame, spring and locking block in cooperation, the magnetic ring is locked, which ensures that the nut is stably pressed against the front end of the iron frame, and thus the mounting frame is stably installed in the adjustment frame. This improves the stability after the adjustment of multiple cutting chord positions, and thus ensures the cutting effect of porous sintered brick blanks. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0027] The present invention will be further described below with reference to the embodiments.
[0028] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 An adjustable brick cutting device includes a cutting table 100, with electric push rods 200 fixedly connected to both sides of the inner wall of the cutting table 100. It also includes an anti-loosening mechanism 300, which includes an adjusting frame 301 fixedly connected to the telescopic end of the electric push rods 200. Several mounting brackets 302 are slidably connected to the inner wall of the adjusting frame 301. A cutting chord 303 is fixedly connected to the surface of the mounting bracket 302. An iron frame 304 is fixedly connected to the front end of the adjusting frame 301. A screw 305 is fixedly connected to the front end of the mounting bracket 302. A nut 306 is threadedly connected to the surface of the screw 305. A magnetic ring 313 is fixedly connected to the surface of the nut 306. One end of the magnetic ring 313 is magnetically attracted to the front end of the iron frame 304.
[0029] Slit chord 303 is a carbon fiber chord component, characterized by its light weight, high strength, and high elastic modulus. The slit chord 303 of the carbon fiber chord component exhibits good flexibility, enabling it to adapt to the slitting requirements of porous sintered brick blanks of different shapes and sizes, while also possessing excellent chemical stability.
[0030] In this embodiment of the invention, when the porous sintered brick blank needs to be cut, multiple mounting brackets 302 are slid into the adjusting frame 301 in sequence and distributed at corresponding intervals. Nuts 306 are threaded onto the surface of screw rod 305 and abut against the front end of iron frame 304, so that magnetic ring 313 is attracted to the front end of iron frame 304, thereby increasing the resistance to rotation of nut 306 and making the mounting bracket 302 stably installed in adjusting frame 301. The other mounting brackets 302 are locked in the same manner. The mold containing the porous sintered brick blank is transported to the cutting table 100. The electric push rod 200 is manually activated. The telescopic end of the electric push rod 200 moves down, causing the adjusting frame 301 to move down. The downward movement of the adjusting frame 301 causes multiple cutting chords to move down and cut the porous sintered brick blank into the corresponding size. At this time, the cut porous sintered brick blank is transported to the next stage for processing.
[0031] In this embodiment of the utility model, the mounting frame 302 and the adjusting frame 301 cooperate with each other to facilitate precise adjustment of the spacing of each cutting chord 303 according to the width of the porous sintered brick blank. The iron frame 304, screw 305, nut 306 and magnetic ring 313 cooperate with each other to lock the adjusted mounting frame 302, thereby ensuring the stability of the multiple cutting chords 303 after position adjustment, avoiding displacement of the cutting chords 303 during cutting, and thus ensuring the cutting effect of the porous sintered brick blank.
[0032] In some embodiments, such as Figure 3-4 As shown, in a preferred embodiment of this utility model, a limiting frame 307 is slidably connected to the inner wall of the iron frame 304. The rear end of the limiting frame 307 contacts one end of the magnetic ring 313. A spring 308 is fixedly connected to the end of the limiting frame 307. The top end of the spring 308 is fixedly connected to the inner top wall of the iron frame 304. Two actuating rods 311 are fixedly connected to the surface of the nut 306. A locking block 309 is slidably connected to the upper end of the inner wall of the iron frame 304. The surface of the locking block 309 is slidably connected to the inner wall of the limiting frame 307. A limiting hole 312 is opened at the front end of the locking block 309. The inner wall of the limiting hole 312 is slidably connected to the upper end of the inner wall of the iron frame 304.
[0033] Both spring 308 and block 309 are polyurethane rubber components, which have good elasticity and damping properties.
[0034] In this embodiment of the utility model, multiple magnetic rings 313 are adsorbed on the front end of the iron frame 304. When the limiting frame 307 is loosened, the elastic force of the spring 308 pushes the limiting frame 307 to automatically move down and abut against one end of the magnetic ring 313. At this time, the push block 309 slides in the iron frame 304 and slides into the limiting frame 307.
[0035] In this embodiment of the utility model, the locking of the magnetic ring 313 is achieved by the cooperation of the limiting frame 307, the spring 308 and the locking block 309, thereby ensuring that the nut 306 is stably pressed against the front end of the iron frame 304, and thus the mounting frame 302 is stably installed in the adjusting frame 301, thereby improving the stability after the position adjustment of multiple cutting chords 303, and thus ensuring the cutting effect of the porous sintered brick blank.
[0036] In some embodiments, such as Figure 3 As shown, in a preferred embodiment of the present invention, the end of the adjustment frame 301 is provided with scale lines, and the front end of the mounting bracket 302 is fixedly connected to a transparent block 310. The surface of the transparent block 310 is triangular, and the transparent block 310 is a transparent acrylic block component.
[0037] In this embodiment of the utility model, the scale lines and the transparent block 310 work together to achieve precise starting adjustment of the position of the mounting frame 302 within the adjustment frame 301, thereby precisely adjusting the cutting size of the porous sintered brick blank and ensuring the cutting effect of the porous sintered brick blank.
[0038] It should be noted that the cutting table 100, electric push rod 200, iron frame 304, screw 305, nut 306 and magnetic ring 313 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electric push rod 200 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
