[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0028] like Figure 1As shown, a specific embodiment of the present invention discloses a device for processing wood fibers on the surface of ceramic tile blanks, including a conveying platform 100 and a burning device 200; the burning device 200 is installed across the top of the conveying platform 100, and is used for open flame burning of the surface wood fibers of the blanks conveyed on the conveying platform.

[0029] The above-mentioned equipment for processing wood fibers on the surface of ceramic tile blanks smoothly conveys ceramic tile blanks through a conveyor platform, and burns the surface wood fibers of the passing blanks with open flames through a burning device, so that the surface wood fibers are completely removed, which facilitates subsequent glaze forming and improves the overall product quality. It should be noted that the conveyor platform is a roller conveyor line structure, which is a common conveying equipment and can be purchased or customized on the market. The specific structure will not be described in detail.

[0030] Furthermore, if Figures 2 to 6 As shown, the burning device 200 includes at least one flame-spraying pipe 240 and at least two suction pipes. Both the flame-spraying pipe and the suction pipe extend along the width direction of the conveyor platform, and the flame-spraying pipe is located between the suction pipes. The suction pipes are connected to an external negative pressure system via a first manifold to provide upward suction for the wood fibers, so that the free ends of the wood fibers are separated from the surface of the blank. The flame-spraying pipe is connected to an external gas tank, and the gas sprayed is ignited to provide open flame burning for the wood fibers. The burning smoke is sucked and collected through the suction pipes.

[0031] By providing a suction pipe, on the one hand, the wood fibers on the surface can be attracted, so that the wood fibers are separated from the blank and are located away from the surface of the blank, which is convenient for complete burning; on the other hand, the smoke generated during the combustion process can be sucked and collected for subsequent unified treatment, preventing the smoke from being directly discharged and causing pollution; and, by providing suction pipes on both sides of the flamethrower, it is also possible to attract the burning flame, causing the flame to spread to both sides, expanding the scope of combustion, and further ensuring the combustion effect; furthermore, the suction pipe can also be used to suck out some of the incompletely burned gas, reducing safety hazards.

[0032] Furthermore, if Figure 6As shown, the number of flame-spraying pipes is 2 and the number of suction pipes is 3; the three suction pipes and the two flame-spraying pipes are arranged at intervals; the combustion range is effectively expanded to ensure that the wood fiber is completely processed; and the multiple suction pipes provide a sufficient suction range, effectively preventing smoke from being discharged, and can also effectively guide and spread the flame; the three suction pipes are connected to the external negative pressure system through the first manifold 260; the two flame-spraying pipes 240 are connected to the external gas tank through the second manifold 250, and the second manifold 250 is provided with a solenoid valve 251; the burning device includes an igniter 270, which is used to ignite the gas. The firearm is provided with electrode heads corresponding to the jet holes of multiple flamethrower tubes, and the ignition effect is achieved through the discharge of the electrode heads; and a gantry is set up on the upstream side of the conveyor platform, and an infrared sensor 400 for detecting the entry of the blank is installed on the gantry. When it is detected that the blank to be processed enters, the solenoid valve will be opened and the igniter will be started to ignite the gas and form an open flame to burn the wood fiber of the blank passing below; it should be pointed out that when the upstream production line has continuous output, the burning action can be maintained by setting it, without triggering the start, thereby reducing the frequency of ignition back and forth.

[0033] Furthermore, two jet holes 241 extending along the length are provided at the bottom of the flame tube 240. The jet holes 241 are tilted relative to the bottom end of the flame tube 240 toward the suction pipe on one side. The cross-sections of the two jet holes are distributed in an eight-shaped pattern, so that the gas is sprayed toward the suction pipe close to it, thereby better allowing the gas to spread to both sides. The bottom of the suction pipe is provided with suction holes extending along the length, providing a sufficiently large suction coverage area to better attract wood fibers and combustion smoke.

[0034] Furthermore, the three suction pipes are respectively a first suction pipe 210, a second suction pipe 220, and a third suction pipe 230 along the conveying direction of the conveying platform; a first suction hole 211 and a second suction hole 212 are provided on the bottom surface of the first suction pipe 210, the second suction hole is located in the middle of the first suction pipe, and the first suction hole is located on the side of the second suction hole away from the second suction pipe; a third suction hole 221 is provided in the middle of the bottom surface of the second suction pipe 220; a fourth suction hole 231 and a fifth suction hole 232 are provided on the bottom surface of the third suction pipe 230, the fourth suction hole is located in the middle of the third suction pipe, and the fifth suction hole is located on the side of the fourth suction hole away from the second suction pipe; the above-mentioned structural arrangement provides sufficient suction for the blank during the burning process, and effectively expands the spread of the flame, so that the wood fiber can be effectively burned and cleaned, and the burning and cleaning quality is improved; and the first suction hole and the fifth suction hole form a double suction effect on the periphery to further prevent the discharge of smoke.

[0035] Furthermore, a roller brush device 300 is provided on the upstream side of the burning device 200, and the roller brush device 300 is installed across the top of the conveyor platform 100; the roller brush device is used to roll and brush the top surface of the passing blank to loosen the surface wood fibers, loosen the wood fibers initially, and prevent the wood fibers from adhering to the surface of the blank, so that the wood fibers can be sucked upward by suction later, so that the free ends can be separated from the surface of the blank, further improving the burning and cleaning quality.

[0036] Furthermore, if Figure 7 As shown, the roller brush device 300 includes a brush roller 310 and a motor 320 for driving the brush roller to rotate; the motor is installed on the frame, and the brush roller 310 is rotatably mounted on both sides of the top of the conveyor platform 100, spanning the top of the conveyor platform. The motor drives the brush roller to rotate and actively cleans the top surface of the blank to ensure that wood fibers are loosened from the surface of the blank, reducing adhesion and making it loose.

[0037] Furthermore, if Figure 8 As shown, an air cavity 312 is provided inside the roller body 311 of the brush roller 310, and a plurality of sixth air suction holes 313 extending in the length direction are provided on the outer wall of the roller body 311, and the plurality of sixth air suction holes are distributed in a circular array around the axis of the roller body; a rotating shaft is fixed at both ends of the roller body, and the roller body is mounted on the frame by rotating the rotating shaft; the rotating shaft close to the first manifold is a hollow structure and is connected to the air cavity; and the rotating shaft is connected to the first manifold 260 through a rotary joint 330; the rotating shaft at the other end is connected to the output shaft of the motor; the outer surface of the roller body 311 The wall is provided with a plurality of slots 314 extending along the length direction. The slots are arranged in a circular array around the axis of the roller body, and the slots 314 are arranged at intervals with the sixth air suction holes 313. A brush strip 315 for cleaning the blank is installed at each slot 314. This structural design allows the brush strip to roll over the surface of the blank, loosening wood fibers and raising dust on the surface. Under the action of negative pressure suction, the raised dust is sucked and collected, and the suction force further loosens the wood fibers, facilitating subsequent processing.

[0038] In addition, the brush roller and the suction pipe share a negative pressure system, which is also connected to the exhaust gas treatment device. Dust, debris, and burning flue gas in the negative pressure suction process are filtered and treated to reduce the discharge of exhaust gas and prevent it from affecting the external environment. It should be noted that the motor, negative pressure system, exhaust gas treatment device, solenoid valve, infrared sensor, and igniter are all electrically connected to the electrical control box to achieve coordinated operation of various electrical components and facilitate regulation by staff. In addition, the above-mentioned electrical components are all commonly used electrical equipment structures, which can be purchased and used on the market, and the specific structure will not be repeated.

[0039] Furthermore, the slot opening is a narrowing structure, the bottom of the brush strip is adapted to the shape of the slot, and the brush strip is clamped in the slot; the slot 314 extends from one end close to the rotary joint 330 to the end face of the roller body 311, and a limiting ring 316 is installed on the outside of the end face by bolts, and the limiting ring is used to seal the end of the slot so that the brush strip is clamped in the slot; the slot includes but is not limited to T-slots and dovetail slot structures, and the brush strip includes a clamp and bristles fixed and densely arranged at the clamp, the clamp is adapted to the shape of the slot, and is slidably clamped in the slot, and the bristles extend outward from the slot opening of the slot; the brush strip and the roller body are provided with a detachable structure, which is convenient for overall assembly and subsequent disassembly and replacement of parts.

[0040] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various modifications or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
