DETAILED DESCRIPTION

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure, and different embodiments may be combined arbitrarily without conflict. Therefore, the drawings and descriptions are considered to be illustrative in nature and not restrictive.

[0028] As a first aspect of the embodiments of the present disclosure, the embodiments of the present disclosure provide an automatic cleaning mechanism for a metal plate. Figure 1 The metal plate automatic cleaning mechanism 1000 includes: a raw material transmission unit 100 and an electrostatic derivation unit 200. The raw material transmission unit 100 includes a metal suction cup frame 110. The electrostatic derivation unit 200 is fixed on the metal suction cup frame 110. The electrostatic derivation unit 200 includes a wire 210, a telescopic cylinder 220 and a grounding wire (not shown in the figure). The wire 210 is electrically connected to the metal suction cup frame 110. The telescopic cylinder 220 can control the extension and retraction of the wire 210. The grounding wire is electrically connected to the metal suction cup frame 110.

[0029] Therefore, when the metal suction cup frame 110 adsorbs a metal plate (not shown in the figure) for processing, for example, when multi-layer paper (including impregnated surface paper, colored paper, impregnated kraft paper, etc.) and a metal plate (such as a steel plate, a fish head plate, etc.) are hot-pressed, the telescopic cylinder 220 controls the extension and retraction of the wire 210, and the wire 210 can be electrically connected to the metal plate, thereby forming an effective static electricity desorption circuit between the metal plate, the wire 210, the metal suction cup frame 110 and the grounding wire, thereby desorbing the static electricity generated on the metal plate, reducing the static electricity adsorption of dust, paper scraps, impurities, foreign matter, etc. on the surface of the metal plate, realizing automatic cleaning of the metal plate, and improving product yield; and the automatic cleaning mechanism of the metal plate is simple and efficient, which can improve production efficiency.

[0030] In a possible implementation, the static electricity removal unit 200 may be fixed on the metal suction cup frame 110 by a metal fixing member (not shown in the figure).

[0031] In one possible implementation, reference Figure 2 , the static electricity extraction unit 200 may further include: a metal rack 240 and a grounding socket 250, the metal rack 240 and the metal suction cup rack 110 are electrically connected, the grounding wire 230 and the metal rack 240 are electrically connected, and the grounding socket 250 is arranged at the end of the grounding wire 230 away from the metal rack 240. Therefore, when the wire 210 and the metal sheet are electrically connected, an effective static electricity extraction circuit is formed between the metal sheet, the wire 210, the metal suction cup rack 110, the metal rack 240 and the grounding wire 230, and static electricity can be effectively extracted through the grounding socket 250, thereby reducing the static electricity adsorption of dust, paper scraps, impurities, foreign matter, etc. on the surface of the metal sheet, and realizing efficient automatic cleaning of the metal sheet. Specifically, refer to Figure 2 The raw material transmission unit 100 may include a suction cup 120 , which is connected to the metal suction cup frame 110 , and the material to be processed may be adsorbed by the suction cup 120 .

[0032] In a possible implementation, the material of the wire 210 is not particularly limited, as long as it has good electrical conductivity. In one example, the material of the wire 210 may include a copper core wire, such as a copper wire or a tinned copper wire. In one example, the cross-sectional area of ​​the wire 210 may be 25-120 mm 2 The length of the wire 210 may be no greater than 2 m. Thus, the wire can conveniently conduct static electricity generated on the metal plate.

[0033] In one possible implementation, reference Figure 3 The metal plate automatic cleaning mechanism 1000 may further include a first station 10 and a second station 20 arranged in sequence. In one example, the first station 10 and the second station 20 may be arranged according to a processing sequence, for example, during processing, the first station 10 is first passed, and then the second station 20 is transferred.

[0034] In a possible implementation, the raw material transmission unit 100 and the static electricity extraction unit 200 are both located at the first station 10; the metal plate automatic cleaning mechanism 1000 further includes: an automatic cleaning unit 300, which can be located at the second station 20. Specifically, the automatic cleaning unit 300 includes a static electricity removal ion air knife 310, a purge roller 320, and a brush dust-adhesive roller 330 arranged in sequence. Therefore, when the metal suction cup frame 110 adsorbs the metal plate for processing and enters the second workstation, it can pass through the anti-static ion air knife 310, the purge roller 320 and the brush dust-sticking roller 330 in sequence. The electrostatic ion air knife 310 can further eliminate the static electricity on the surface of the metal plate, the purge roller 320 can blow away impurities and foreign matter on the surface of the metal plate, and the brush dust-sticking roller 330 can further roll and brush to clean the metal plate. Therefore, the automatic cleaning mechanism 1000 for the metal plate has a good automatic cleaning function, which reduces the labor intensity of workers in the prior art when manual cleaning is performed, and the cleaning is more thorough, which can eliminate cleaning blind spots and improve cleaning efficiency, thereby improving the yield of production products. In addition, the automatic cleaning mechanism for the metal plate is simple and efficient, with a high degree of automation, which improves production efficiency.

[0035] In one possible implementation, reference Figure 4 , the anti-static ion air knife 310 may include a first air inlet pipe 313, a first air inlet 311 and an electric ionization rod 312, whereby the anti-static ion air knife 310 blows out an ion flow through the first air inlet pipe 313 and the first air inlet 311, forming a uniform anti-static ion air curtain above the electric ionization rod 312 and blowing on the metal sheet, which can instantly neutralize the residual static charge of the metal sheet and further remove static electricity. In a possible embodiment, when the metal sheet after further anti-static ion air knife 310 removes static electricity runs above the purge roller 320, the purge roller 320 may include a second air inlet pipe 323, a second air inlet 321 and a nozzle 322, and the purge roller 320 will spray compressed air to the metal sheet through the nozzle 322 to purge impurities and foreign matter adsorbed on the metal sheet, thereby further cleaning the metal sheet. In a possible implementation, the brush dust sticking roller 330 may include a brush 331 and a conveying track 332. When the metal sheet runs to the brush dust sticking roller 330, the brush 331 will roll and brush the surface of the metal sheet again to clean it.

[0036] In one possible implementation, reference Figure 4 The automatic cleaning unit 300 further includes a control cylinder 340, referring to Figure 4The control cylinder 340A and the control cylinder 340B are shown in the figure. The control cylinder 340 can control the static electricity removal ion air knife 310, the purge roller 320 and the brush dust sticking roller 330 to rise and fall in sequence. In a possible implementation, after the metal sheet is de-staticized and cleaned by the static electricity removal ion air knife 310, the purge roller 320 and the brush dust sticking roller 330 in sequence, the control cylinder 340 can be lowered to retract the automatic cleaning unit 300 and wait for the next round of cleaning instructions for the metal sheet.

[0037] As a second aspect of the disclosed embodiment, the disclosed embodiment provides a fireproof board production device, which includes: the metal plate automatic cleaning mechanism described in any of the above items. Therefore, the fireproof board production device has all the features and advantages of the metal plate automatic cleaning mechanism described above, which will not be repeated here. In general, the fireproof board production device realizes the automatic cleaning of the metal plate and improves the product yield; and the cleaning is simple and efficient, which improves the production efficiency.

[0038] The existing production process for preparing fireproof boards involves the stacking, stacking and transfer of a large amount of paper materials, impregnated materials (i.e. materials impregnated with glue), and metal plates (such as steel plates and fish head plates, etc.), as well as the process of high-temperature hot pressing (135°C-140°C). The paper scraps, dust, foreign matter, etc. at the production site are easily adsorbed on the metal plates (such as steel plates and fish head plates, etc.) at a high ambient temperature, forming an apparent defect on the surface of the product when entering the next round of hot pressing cycle, resulting in the loss of defective products. In order to clean the hidden dangers of defective products adsorbed on the steel plates and fish head plates, the existing solution is to use manual cleaning at the laying position and the board output position respectively. Manual cleaning has certain blind spots, and most of the impurities (paper scraps, dust, foreign matter, etc.) on the site are attached to the metal plates (such as steel plates and fish head plates, etc.) in the form of electrostatic adsorption. Manual cleaning may not be able to completely remove the electrostatic adsorption; and in the mode of continuous production, manual cleaning has a certain labor intensity; in the mode of manual cleaning at two workstations, there is a certain loss of working time. The fireproof board production device according to the embodiment of the present disclosure can form an effective static electricity conduction circuit to conduct away the static electricity generated on the metal plate, and the static electricity can be eliminated again and automatically cleaned through the automatic cleaning unit, thereby reducing the static electricity adsorption of dust, paper scraps, impurities, foreign matter, etc. on the surface of the metal plate, realizing automatic cleaning of the metal plate and improving product yield; and the cleaning mechanism is simple and efficient, thereby improving production efficiency.

[0039] In one possible implementation, reference Figure 8The fireproof board production device 2000 includes the aforementioned metal plate automatic cleaning mechanism 1000, the metal plate automatic cleaning mechanism 1000 includes a first station 10 and a second station 20 arranged in sequence, the raw material transmission unit 100 and the static electricity extraction unit 200 are both located at the first station 10; the metal plate automatic cleaning mechanism 1000 further includes: an automatic cleaning unit 300 located at the second station 20, the automatic cleaning unit 300 includes: an anti-static ion air knife 310, a purge roller 320, a brush dust sticking roller 330 and a control cylinder 340, the control cylinder 340 controls the anti-static ion air knife 310, the purge roller 320, and the brush dust sticking roller 330 to rise and fall in sequence. Specifically, the fireproof board production device 2000 further includes: a raw material station 30 and a plate-out station 40 arranged in sequence, wherein the first station 10 is located between the raw material station 30 and the plate-out station 40, and the second station 20 is located between the first station 10 and the plate-out station 40. Therefore, when the fireproof board production device is used to prepare the fireproof board, when the multi-layer paper (including impregnated surface paper, colored paper, impregnated kraft paper, etc.) and the metal plate (such as steel plate, fish head plate, etc.) are hot pressed, the metal plate passes through the electrostatic desorption unit 200 and the automatic cleaning unit 300 in turn, which can effectively reduce the static electricity generated on the surface of the metal plate, thereby reducing impurities adsorbed by static electricity, and the metal plate can be automatically cleaned, further improving the cleanliness of the plate surface, and improving the product yield and production efficiency.

[0040] In a possible implementation, when the metal suction cup frame 110 absorbs the metal sheet, the telescopic cylinder 220 can control the wire to extend and be electrically connected to the metal sheet; further, an effective static electricity extraction circuit can be formed between the metal sheet, the wire 210, the metal suction cup frame 110 and the ground wire 230, thereby extracting the static electricity generated on the metal sheet, reducing the static electricity absorption of dust, paper scraps, impurities, foreign matter, etc. on the surface of the metal sheet, and realizing automatic cleaning of the metal sheet. In a possible implementation, when the metal suction cup frame 110 absorbs the non-metallic sheet, the telescopic cylinder 220 controls the wire 210 to retract.

[0041] In a possible implementation, when the metal suction cup frame 110 adsorbs metal plates, the control cylinder can control the operation of the static electricity removal ion air knife, the purge roller, and the brush dust-sticking roller; when the metal suction cup frame 110 adsorbs non-metallic plates, the control cylinder can retract and control the static electricity removal ion air knife, the purge roller, and the brush dust-sticking roller. Therefore, in the fireproof board production device 2000, when metal plates are used in the production process, the static electricity extraction unit 200 can be used to effectively remove static electricity, and when plates of other materials are used, the static electricity extraction unit 200 can be disconnected without affecting the normal production process; similarly, in the fireproof board production device 2000, when metal plates are used in the production process, the automatic cleaning unit 300 can be used to effectively remove static electricity and clean them, and when plates of other materials are used, the automatic cleaning unit 300 is in a standby state without affecting the normal production process.

[0042] In one possible implementation, reference Fig. 9 The fireproof board production device 2000 may further include: a central control unit 2100, which can control the telescopic cylinder 220 and the control cylinder operation according to the type of material adsorbed by the metal suction cup frame 110, thereby more intelligently and automatically removing static electricity and cleaning the metal plate.
