Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, specifically to a flamed stone slab processing machine. Background Technology

[0002] Flamed granite is a processing method for granite. First, natural granite is sawn into slabs. After the surface of the slabs is initially ground, they are placed on a fixed frame. Then, the surface after initial grinding is flame-burned. The characteristic feature is that the flame-burning uses acetylene, oxygen, and a spray gun. Through the high-temperature flame burning, due to the uneven expansion caused by heating, a slightly uneven surface similar to lychee surface is formed.

[0003] For example, Chinese patents CN218398875U and CN220219123U, published on December 22, 2023, disclose a flamed plate surface processing device, including a mounting base. A flame-spraying mechanism is provided on the outer side of the mounting base. The flame-spraying mechanism includes a mounting frame, a sliding seat, a sliding bracket, a drive motor, a drive disc, a connecting rod, and a drive column. A cleaning mechanism is provided on the side wall of the mounting base, and a cooling mechanism is provided on the side of the mounting base opposite the cleaning mechanism. The flame-spraying mechanism performs a reciprocating singeing operation on the flamed plate, ensuring the uniformity of the singeing operation. The reciprocating operation of the sliding bracket is achieved through a crank-connecting rod structure, providing high operational stability and ensuring the flame-spraying mechanism operates smoothly for extended periods, thus extending the device's service life. Furthermore, this structure has low usage and manufacturing costs, improving the economic efficiency of the device's use and manufacturing. The cleaning mechanism cleans the flamed plate, ensuring its cleanliness during the singeing operation and improving the quality of the singeing process.

[0004] As can be seen from the above patents, the flamed granite surface processing device uses a reciprocating sliding bracket to drive a flame head to perform a reciprocating flame-scorching operation on the stone. To ensure the surface of the stone is covered, uneven burning is easily caused, especially since the reciprocating motion of the flame head during automatic conveying can also lead to uneven flame-scorching. Therefore, this utility model provides a flamed granite machine for stone to solve the above problems. Summary of the Invention

[0023] Example 1 Reference Figure 1-5 This utility model discloses a stone flamed slab machine, including a worktable 1, a conveyor roller 2, a cleaning component 3, an electric lifting component 4, a flame-spraying mechanism 5, a dust-collecting mechanism 6, a blower 7, and a controller 8. The conveyor roller 2, which automatically conveys the stone, is rotatably connected inside the worktable 1; the cleaning component 3 for cleaning the stone surface, the electric lifting component 4 for automatically lifting the flame-spraying mechanism 5, and the blower 7 for rapidly dissipating heat from the flamed slab are respectively installed sequentially along the stone conveying direction on the worktable 1 and one side of the worktable 1; the flame-spraying mechanism 5 for flame-spraying the stone is mounted on the electric lifting component 4; the flame-spraying mechanism 5 includes an air inlet 51, an air storage box 52, and a... arranged sequentially from top to bottom. Several flame guns 53 are fixedly installed at the top center and bottom of the gas storage tank 52, respectively, for the air inlet 51 for mixed gas feeding. The flame guns 53 are arranged in two rows along the stone conveying direction and the two rows of flame guns 53 are staggered. The angle between the nozzle of the front row of flame guns 53 and the horizontal direction and the angle between the nozzle of the rear row of flame guns 53 and the horizontal direction are 40~60º and 20~40º, respectively, to ensure that the flames evenly distributed in the width direction can cover the stone surface.

[0024] In an optional embodiment, the cleaning component 3 includes an electric brush roller 31 for cleaning the stone and two fixed brackets 32. The two ends of the electric brush roller 31 are rotatably connected to the fixed brackets 32, which are fixedly connected to the workbench 1. The fixed brackets 32 fix and support the electric brush roller 31, and the rotating electric brush roller 31 cleans the dust on the stone.

[0025] In an optional embodiment, the electric lifting assembly 4 includes a slide rail 41, a plurality of electric sliders 42, a support plate 43, and a fixed frame 44. The electric sliders 42 are slidably connected to the slide rail 41, which is fixedly connected to both ends of the workbench 1. The two ends of the support plate 43 are respectively mounted on the electric sliders 42 and support the bottom end of the flame-spraying mechanism 5. The electric sliders 42 slide up and down, driving the support plate 43 to move up and down, thereby driving the flame-spraying mechanism 5 to move up and down. The two ends of the fixed frame 44 are respectively fixed to the slide rail 41 by movable bolts, and the outer wall of the flame-spraying mechanism 5 is slidably connected to the fixed frame 44. The fixed frame 44 limits the flame-spraying mechanism 5 to the left and right to prevent the flame-spraying mechanism 5 from shaking, and also limits the flame-spraying mechanism 5 in the up and down direction. The height of the fixed frame 44 can be adjusted by movable bolts.

[0026] In an optional embodiment, a dust collection mechanism 6 for collecting dust generated by flame combustion is fixedly installed on the flame-spraying mechanism 5. The dust collection mechanism 6 includes an outer cover 61 and an inner cover 62. The cross-sections of the outer cover 61 and the inner cover 62 are trapezoidal. The cavity between the outer cover 61 and the inner cover 62 forms a dust collection hood. The top of the outer cover 61 is provided with an air extraction hole 64 that communicates with an exhaust fan (not shown in the figure) with a filter. The inner wall and bottom of the inner cover 62 are evenly covered with a plurality of dust collection holes 63. Thus, the dust collection hood between the outer cover 61 and the inner cover 62 is in a negative pressure state under the action of the exhaust fan, so that air can be absorbed by the plurality of dust collection holes 63 on the inner wall and bottom of the inner cover 62, and then cooperate with the filter to collect and filter the dust generated by flame combustion.

[0027] In an optional embodiment, a controller 8 is provided on the upper front side of the workbench 1. The controller 8 is electrically connected to the conveyor roller 2, the electric brush roller 31, the electric slider 42, the exhaust fan, and the blower 7.

[0028] Example 2 like Figure 3 As shown, the present invention proposes a flamed stone slab machine. Compared with the first embodiment, this embodiment further includes: each flame gun 53 is equipped with a solenoid valve 54 and electrically connected to the controller 8. The controller 8 can control the opening of the flame guns 53 to adapt to different specifications of stone and save fuel.

[0029] The working principle and usage process of this utility model are as follows: According to the specifications of the stone, the controller 8 activates the electric slider 42, which moves up and down, causing the support plate 43 to rise and fall, which in turn causes the flame-spraying mechanism 5 to rise and fall, adjusting the height of the two rows of flame-spraying guns 53. Then, the controller 8 activates the conveyor roller 2 to transport the stone forward and activates the electric brush roller 31 to clean the surface of the stone. The flame-spraying guns 53 then evenly flame-spray the stone, and the controller 8 controls the activation of the flame-spraying guns 53 to adapt to stones of different widths. The controller 8 then activates the exhaust fan and the blower 7 in sequence. The dust generated by the flame-spraying is sucked in and filtered by multiple dust-collecting holes 63 on the inner wall and bottom of the inner cover 62. The blower 7 then quickly dissipates heat from the flame-sprayed plate.

[0030] Of course, the embodiments described in this specific implementation are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
