Description

Technical Field

[0001] This utility model relates to the field of marble processing, and in particular to a marking device for marble processing. Background Technology

[0002] Marble is a metamorphic rock formed from pre-existing rocks in the Earth's crust under high temperature and pressure. The internal forces of the Earth's crust cause qualitative changes in the original rocks. These qualitative changes refer to alterations in the structure, texture, and mineral composition of the original rocks; the new rock type formed through this process is called a metamorphic rock. Marble is mainly composed of calcite, limestone, serpentine, and dolomite, with calcium carbonate as its primary component. During marble processing, lines are often drawn, leaving marks on the marble surface and creating numerous marble fragments.

[0003] A search of Chinese patent publication number CN220280100U reveals a marking device for marble processing. This patent uses a motor to control the movement of a housing, which in turn moves a fixed plate, causing the marking mechanism to move and adjust its position. This allows for marking lines on different parts of the marble. While marking lines, the device also leaves marks on the marble surface. A fan is activated, drawing air through a duct below the fixed plate to suck marble debris into a dust collection chamber. A filter then traps and filters the debris, keeping it within the chamber. Excess air is exhausted through the outlet. This significantly improves work quality and efficiency compared to traditional devices.

[0004] However, the marble placed on the base may become crooked, and for larger pieces of marble, the weight makes repositioning difficult. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-5As shown, a marble marking device includes a workbench 1, a marking mechanism on the top of the workbench 1, an electric slide rail 201 on the top of the workbench 1, a mounting frame 202 slidably connected to the electric slide rail 201, the mounting frame 202 being U-shaped with its opening facing downwards, a rotary motor 203 bolted to the front side of the mounting frame 202, the output end of the rotary motor 203 being connected to a first lead screw 204 via a coupling, the first lead screw 204 being rotatably connected between the front and rear inner walls of the mounting frame 202, a slider 205 threadedly connected to the first lead screw 204, the slider 205 being slidably connected to the mounting frame 202, a first hydraulic cylinder 206 fixedly connected to the bottom of the slider 205, a mounting plate 207 fixedly connected to the bottom of the first hydraulic cylinder 206, a marking assembly 208 on the bottom of the mounting plate 207, the marking assembly 208 including a cutting blade fixed to the mounting plate 207, the bottom of the cutting blade being conical.

[0026] The top of the workbench 1 is also equipped with a limiting mechanism, which includes a first limiting plate 303 and a second limiting plate 311. The limiting mechanism also includes an adjustment component, which is used to adjust the distance between the first limiting plate 303 and the second limiting plate 311. The adjustment component includes two first vertical plates 304 bolted to the top of the workbench 1. One side of one of the first vertical plates 304 is bolted to a stepper motor 305. The output end of the stepper motor 305 is connected to a second lead screw 306 through a coupling. The second lead screw 306 is rotatably connected between the two first vertical plates 304. The top of the workbench 1 is also bolted to two second vertical plates 307. A guide rod 308 is fixedly connected between the two second vertical plates 307. A slide plate 309 is threaded onto the second lead screw 306. The slide plate 309 is also slidably connected to the guide rod 308. A connecting post 310 is fixedly connected to the side of the slide plate 309 near the first limiting plate 303. The other end of the connecting post 310 is fixedly connected to the second limiting plate 311.

[0027] The top of the workbench 1 is bolted to a support frame 301. A first limiting plate 303 is installed on the support frame 301. The first limiting plate 303 moves up and down through a lifting assembly. The lifting assembly includes an electric push rod 302, which is fixedly connected to the support frame 301. The bottom of the electric push rod 302 is fixedly connected to the first limiting plate 303. The electric push rod 302 drives the first limiting plate 303 to move upward, so that marble can be loaded and unloaded from the notch below the first limiting plate 303.

[0028] The top of the workbench 1 has several through holes, and the workbench 1 has an installation groove. A support assembly is installed in the installation groove. The support assembly includes a second hydraulic cylinder 401, which is fixedly connected to the installation groove inside the workbench 1. A horizontal plate 402 is fixedly connected to the top of the second hydraulic cylinder 401. Several ball bearings 403 are rotatably connected to the top of the horizontal plate 402. The ball bearings 403 are located below the through holes on the top of the workbench 1. During limiting and unloading, the second hydraulic cylinder 401 causes the horizontal plate 402 to drive the ball bearings 403 to move upward. The horizontal plate 402 and the ball bearings 403 support the marble, reducing the pressure between the marble and the workbench 1 and reducing friction.

[0029] Working Principle: In use, a relatively regular square marble is first placed on the workbench 1. The second hydraulic cylinder 401 controls the horizontal plate 402 to move the ball bearing 403 upwards until the ball bearing 403 contacts the marble, supporting it and reducing pressure and friction between the marble and the workbench 1. The stepper motor 305 is then activated, driving the second lead screw 306 to rotate. The lead screw 306 drives the sliding plate 309 to move along the guide rod 308. The sliding plate 309 drives the connecting column 310 to move the second limiting plate 311. After the second limiting plate 311 contacts a portion of the marble, it drives the marble to move further. Once a portion of the marble on the other side contacts the first limiting plate 303, the combined action of the first and second limiting plates 303 gradually limits and corrects the marble, ensuring the accuracy of the drawn lines, until both sides of the marble are completely in contact with the first and second limiting plates 303 and 311. Next, by controlling the second hydraulic cylinder 401, the ball bearing 403 moves downward to separate from the marble, increasing the stability during line drawing. By controlling the first hydraulic cylinder 206, the line drawing assembly 208 is lowered to a suitable height. The rotary motor 203 is started, which drives the first lead screw 204 to rotate. The first lead screw 204 drives the slider 205 to move the first hydraulic cylinder 206 and the line drawing assembly 208 to draw lines. The mounting bracket 202 is moved by the electric slide rail 201 to facilitate line drawing at different positions. When the line drawing is finished and the marble needs to be removed from the worktable 1, the first limiting plate 303 is raised by controlling the electric push rod 302. The second hydraulic cylinder 401 is controlled to raise the horizontal plate 402 and the ball bearing 403 to support the marble. Then, the stepper motor 305 is started, which drives the second lead screw 306 to continue moving the second limiting plate 311, thereby pushing the marble towards the end of the worktable 1 for easy unloading.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
