Description

Technical Field

[0001] The present invention relates to the technical field of sheet processing, and particularly to a cutting, wet splitting and dividing process for a fireproof door core board based on wire cutting. Background Art

[0002] Fireproof boards are a kind of fire-resistant building materials, which are widely used in the fields of interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls, etc.

[0003] Chinese Patent Publication No.: CN112589981A discloses a wet splitting process for concrete blocks or boards, which includes the following steps: First, flip preparation: make the inner side of the horizontal curing bottom plate fixed on the flipping table in a horizontal state. After sending the horizontal curing bottom plate to the flipping table and fixing it, the flipping table is flipped by 90°. Then, send the vertical curing bottom plate carrying the vertically stacked blanks to the flipping table and fix it; Second, flip the blanks: the flipping table 103 is flipped by 90° to make the inner side of the fixed horizontal curing bottom plate in a horizontal state; Third, blank curing: send the horizontal curing bottom plate carrying the blanks to the horizontal curing track, and send the horizontal curing bottom plate to the wet splitting machine for splitting work. After splitting, return the blanks to the vertically stacked state and send them to the curing device for curing work.

[0004] When wet splitting the board, it is impossible to adjust the wet splitting position according to the board state, resulting in a low yield of the products after wet splitting. Summary of the Invention

[0005] Therefore, the present invention provides a cutting, wet splitting and dividing process for a fireproof door core board based on wire cutting to overcome the problem that when wet splitting the board in the prior art, it is impossible to adjust the wet splitting position according to the board state, resulting in a low yield of the products after wet splitting.

[0006] To achieve the above object, a cutting, wet splitting and dividing process for a fireproof door core board based on wire cutting is characterized by including:

[0007] Rotate the stacked and trimmed fireproof door core board blanks by 90° to make them stand vertically.

[0008] Through the conveying and separating mechanism, separate the vertically placed fireproof door core board blanks. During the separation of the fireproof door core board blanks, collect the front images and back images of each fireproof door core board blank, and perform image splitting to obtain four edge images of each fireproof door core board blank.

[0009] And perform embryo curing on the fireproof door core board blanks after separation.

[0010] The wet splitting device performs wet splitting on the fireproof door core board blanks after steam curing. The wet splitting device can perform single wet splitting on each of the fireproof door core board blanks. When wet splitting any fireproof door core board blank, by analyzing the four corresponding edge images, the missing distance of the largest missing block and the farthest crack distance of each edge image are obtained, and the clamping center line position during wet splitting is determined according to the quantity and distribution of the effective missing distance and the effective crack distance.

[0011] Furthermore, the conveying and separating mechanism includes a first conveyor belt and a second conveyor belt. Among them, the first conveyor belt can convey at intervals, and the second conveyor belt is continuously conveyed. The first conveyor belt and the second conveyor belt are used to separate the vertically placed fireproof door core board blanks. The running duration of the first conveyor belt each time is T1, the running speed is V, and the stopping duration is T2. The single-layer thickness F of the fireproof door core board blank, F = T1×V, T2 = 1.2T1, and the running speed of the second conveyor belt is V.

[0012] Furthermore, each of the separated fireproof door core board blanks is transported to the embryo steam curing unit by a board transfer vehicle for embryo steam curing;

[0013] The board transfer vehicle can be connected to the end of the second conveyor belt. An even number of rotating rollers are arranged on the board transfer vehicle. The rotating rollers are numbered in sequence. For any rotating roller numbered even, a pressure sensor with the same number is arranged below it. Among the rotating rollers in rotation, when the pressure value detected by the pressure sensor with the largest number value is greater than the preset pressure comparison threshold, the rotation of the corresponding numbered rotating roller is controlled to stop.

[0014] In particular, the rotating rollers are numbered, respectively denoted as the first rotating roller A1, the second rotating roller A2,..., the Nth rotating roller An. Among them, for the rotating roller Aj, j is any even number in 2, 4, 6,..., n, and a pressure sensor Bj is arranged below it.

[0015] A pressure comparison threshold Yz is set in the total control module. For the pressure sensor Bm, the detected pressure value is Y1. In the initial stage when the transfer vehicle starts, m = n.

[0016] If Y1≥Yz, then control the rotating rollers Am and Am - 1 to stop rotating, and at the same time perform iteration on the value of m, making m = m - 2. The pressure value of the pressure sensor Bm is obtained in real time and compared with the pressure comparison threshold Yz until all the rotating rollers stop rotating, determining that the board transfer vehicle is loaded completely, and the board transfer vehicle transports the loaded fireproof door core board blanks to the steam curing unit for steam curing.

[0017] Further, a first image acquisition structure and a second image acquisition structure are arranged above the conveying and separating mechanism. The first image acquisition structure can acquire the image information of the back surface of the separated fire door core board blank, and the second image acquisition structure can acquire the image information of the front surface of the separated fire door core board blank;

[0018] Integrate the acquired image information and mark it in the order of being conveyed to the board transfer vehicle to generate several sets of image information of fire door core board blanks with unique numbers;

[0019] In particular, integrate the acquired image information and mark it in the order of being conveyed to the board transfer vehicle, and record them respectively as,

[0020] The first set of image information of the fire door core board blank C1, the second set of image information of the fire door core board blank C2,..., the kth set of image information of the fire door core board blank Ck, k = n / 2.

[0021] For the pth set of image information of the fire door core board blank Cp, it includes the back surface image information Cp1 of the pth fire door core board blank and the front surface image information Cp2 of the pth fire door core board blank.

[0022] For any set of the image information of the fire door core board blank, when determining the clamping center line position during the wet splitting process, split it, where,

[0023] Take the left edge image of the back surface image information as the first edge image DP1;

[0024] Take the right edge image of the back surface image information as the second edge image DP2;

[0025] Take the left edge image of the front surface image information as the third edge image DP3;

[0026] Take the right edge image of the front surface image information as the fourth edge image DP4.

[0027] Further, for any one of the edge images, obtain its blank missing information, including the edge missing image and the edge crack image, and analyze the edge missing image and the edge crack image to obtain the missing distance of the largest missing block in the edge missing image and the farthest crack distance in the edge crack image;

[0028] Analyze the missing distance of the largest missing block in any one of the edge images and the farthest crack distance in the edge crack image to determine whether there is an effective missing distance or an effective crack distance in the edge image;

[0029] Integrate the effective missing distance and the effective crack distance in all edge images, and determine the clamping center line position during wet splitting according to the maximum value in the effective missing distance or the effective crack distance, combined with the quantities of the effective missing distance and the effective crack distance.

[0030] Further, the effective missing distance needs to satisfy that the missing distance of the largest missing block is greater than or equal to the preset missing distance of the largest missing block;

[0031] The effective missing distance needs to satisfy that the farthest crack distance in the edge crack image is greater than or equal to the preset farthest crack distance.

[0032] Further, for the fire door core board blank without an effective missing distance and an effective crack distance, its clamping center line position is at the position of half of the width of the blank.

[0033] Further, for the fire door core board blank with a single effective missing distance or an effective crack distance,

[0034] Determine the center line deviation distance according to the effective missing distance or the effective crack distance, and determine its clamping center line position.

[0035] Further, for the fire door core board blank with more than one effective missing distance or an effective crack distance, by determining the quantity of the effective missing distance or the effective crack distance, combined with the largest effective missing distance and the largest effective crack distance, integrate and determine the center line deviation distance, and determine its clamping center line position.

[0036] Further, by analyzing the center line deviation distance, determine whether the fire door core board blank can be effectively wet split.

[0037] The wet splitting device includes several groups of wet splitting units. For any wet splitting unit, it can wet split a single fire door core board blank, and it includes,

[0038] A rotating clamping module, on which a rotating shaft, a first telescopic rod, a first clamping component, and a second clamping component are provided. Among them, the length of the first clamping component is longer than that of the second clamping component;

[0039] A fixed clamping module, on which equal third clamping components, fourth clamping components, and a second telescopic rod are provided;

[0040] During wet splitting, control the first telescopic rod to drive the first clamping component and the second clamping component to clamp one side of the fire door core board blank, and the second telescopic rod to drive the third clamping component and the fourth clamping component to clamp the other side of the fire door core board blank;

[0041] The edge of the first clamping component coincides with the position of the clamping center line. The distance between the first clamping component and the third clamping component is L01, and it is set that L01 = 3 cm;

[0042] After the clamping is completed, the rotating shaft rotates to complete the wet splitting. The rotating direction is perpendicular to the end of the first clamping component and points to the side of the second clamping component.

[0043] Compared with the prior art, the beneficial effects of the present invention are as follows. In this application, image detection is performed on the front and back of the fire door core board blank, and the missing distance of the largest missing block at the edge and the farthest crack distance are obtained. Through image analysis, the position of the clamping center line during the wet splitting of each fire door core board blank is determined, ensuring the pertinence during the wet splitting process and improving the yield of the wet split product.

[0044] Furthermore, by setting a conveying and separating mechanism to separate the blanks that are adhered together, it is possible to perform clamping and wet splitting one by one, further ensuring the pertinence during the wet splitting process and improving the yield of the wet split product.

[0045] Furthermore, when there are missing parts or cracks at the edge of the fire door core board blank, the effective use position of the edge of the fire door core board blank is reduced. If wet splitting is performed according to the established wet splitting mode, defects will occur on one side of the board after wet splitting. Therefore, by detecting the distance of the missing part or crack and adjusting the clamping center line position according to the detection result, the pertinence during the wet splitting process is ensured, and the yield of the wet split product is improved.

[0046] Furthermore, by setting a preset missing distance and a preset farthest crack distance, the missing distances and farthest crack distances that are relatively small are discarded, ensuring the rapidity and reasonableness of the wet splitting process.

[0047] Furthermore, for the single valid blank missing information, the center line deviation distance is determined according to the degree of certainty of the single blank missing information, and the center line deviation distances are compared to eliminate the fire door core board blanks that cannot be effectively wet split, ensuring the screening of the fire door core board blanks that can be reasonably wet split and reducing useless processes.

[0048] Further, for the case where there are multiple effective missing distances, the value of the first calculation compensation parameter for the center line deviation distance is determined according to the quantity and distribution of the effective missing distances, ensuring the pertinence during the wet splitting process and improving the yield rate of wet-split products. In particular, for the case where multiple effective missing distances are on the same side, it indicates that there is a greater possibility of problems occurring on the single-sided edge during the wet splitting process and subsequent processing. Therefore, the value of the first calculation compensation parameter for the center line deviation distance is increased to ensure the rationality of wet splitting. For the case where multiple effective missing distances are on different sides, if there are two effective missing distances, it indicates that there is a possibility of problems occurring on both sides during the wet splitting process and subsequent processing. Therefore, the value of the first calculation compensation parameter for the center line deviation distance is appropriately decreased to ensure the rationality of wet splitting.

[0049] Further, for the case where there are multiple effective crack distances, the value of the second calculation compensation parameter for the center line deviation distance is determined according to the quantity and distribution of the effective crack distances, ensuring the pertinence during the wet splitting process and improving the yield rate of wet-split products. In particular, for the case where multiple effective crack distances are on the same side, it indicates that there is a greater possibility of problems occurring on the single-sided edge during the wet splitting process and subsequent processing. Therefore, the value of the second calculation compensation parameter for the center line deviation distance is increased to ensure the rationality of wet splitting. For the case where multiple effective crack distances are on different sides, if there are two effective crack distances, it indicates that there is a possibility of problems occurring on both sides during the wet splitting process and subsequent processing. Therefore, the value of the second calculation compensation parameter for the center line deviation distance is appropriately decreased to ensure the rationality of wet splitting.

[0050] Further, for the case where there are both effective crack distances and effective missing distances, the center line deviation distance is calculated based on the distribution of the effective crack distances and effective missing distances, ensuring the pertinence during the wet splitting process and improving the yield rate of wet-split products.

[0051] Further, the length of the first clamping assembly is longer than that of the second clamping assembly, ensuring reasonable force support during the wet splitting process and improving the yield rate of wet-split products. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Please refer to Figure 1 as shown, which is a schematic flow chart of the cutting and wet splitting process of the fireproof door core board based on wire cutting in the embodiment.

[0060] The present invention provides a cutting and wet splitting process of a fireproof door core board based on wire cutting, including step S1 of cutting and trimming the cast fireproof door core board blank with a wire and stacking it;

[0061] Step S2 of rotating the stacked fireproof door core board blanks by 90° to make them stand vertically and separating the stacked fireproof door core board blanks through a conveying and separating mechanism;

[0063] Step S4 of conveying the steam-cured fireproof door core board blanks to a wet splitting device to perform wet splitting on the fireproof door core board blanks.

[0064] The wet splitting device performs wet splitting on the fireproof door core board blanks after steam curing. The wet splitting device can perform single wet splitting on each of the fireproof door core board blanks. When wet splitting any fireproof door core board blank, by analyzing the corresponding four-edge images, the missing distance of the largest missing block and the farthest crack distance of each edge image are obtained, and the clamping center line position during wet splitting is determined according to the quantity and distribution of the effective missing distance and the effective crack distance.

[0065] In this application, image detection is performed on the front and back of the fireproof door core board blank, and the missing distance of the largest missing block and the farthest crack distance of the edge are obtained. By performing image analysis, the clamping center line position during wet splitting of each fireproof door core board blank is determined, ensuring the pertinence during the wet splitting process and improving the yield rate of the wet-split products.

[0066] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of the conveying and separating mechanism where the end of the second conveyor belt in the embodiment is connected to the board transfer vehicle.

[0067] In the step S2, the provided conveying and separating mechanism includes a first conveyor belt 21 and a second conveyor belt 22. Among them, the first conveyor belt 21 can convey at intervals, the second conveyor belt 22 conveys continuously, the running duration of the first conveyor belt 21 each time is T1, the running speed is V, the stopping duration is T2, the single-layer thickness F of the fireproof door core board blank, F = T1×V, T2 = 1.2T1, and the running speed of the second conveyor belt 22 is V.

[0068] The end of the second conveyor belt 22 can be connected to the board transfer vehicle 3. An even number of rotating rollers 31 are arranged on the board transfer vehicle. The rotating rollers are numbered respectively as the first rotating roller A1, the second rotating roller A2,..., the Nth rotating roller An. Among them, for the rotating roller Aj, where j is any even number in 2, 4, 6,..., n, a pressure sensor Bj is arranged below it.

[0069] A pressure comparison threshold Yz is set in the total control module. For the pressure sensor Bm, the detected pressure value is Y1. In the initial stage when the transfer vehicle starts, m = n.

[0070] If Y1≥Yz, then control the rotating roller Am and the rotating roller Am-1 to stop rotating, and at the same time perform iteration on the value of m, making m = m - 2. Real-time obtain the pressure value of the pressure sensor Bm and compare it with the pressure comparison threshold Yz until all the rotating rollers stop rotating, determine that the board transfer vehicle is loaded, and the board transfer vehicle transports the loaded fireproof door core board blanks to the steam curing unit for steam curing.

[0071] By setting up a conveying and separating mechanism to separate the blanks that are bonded together, it is possible to pick and wet-break them one by one, further ensuring the pertinence during the wet-breaking process and improving the yield rate of the wet-broken products.

[0072] Above the conveying and separating mechanism, a first image acquisition structure 23 and a second image acquisition structure 24 are provided. The first image acquisition structure 23 can acquire the image information on the back of the separated fire door core board blank, and the second image acquisition structure 24 can acquire the image information on the front of the separated fire door core board blank;

[0073] Integrate the acquired image information and mark it in the order of being transported to the sheet transfer vehicle, respectively recorded as,

[0074] The first fire door core board blank image information set C1, the second fire door core board blank image information set C2,..., the kth fire door core board blank image information set Ck, k = n / 2.

[0075] For the pth fire door core board blank image information set Cp, it includes the back image information Cp1 of the pth fire door core board blank and the front image information Cp2 of the pth fire door core board blank;

[0076] Analyze the pth fire door core board blank image information set Cp to determine the clamping center line position during the wet-breaking process; when analyzing the pth fire door core board blank image information set Cp, split the image information set Cp

[0077] Take the left edge image of the back image information as the first edge image DP1;

[0078] Take the right edge image of the back image information as the second edge image DP2;

[0079] Take the left edge image of the front image information as the third edge image DP3;

[0080] Take the right edge image of the front image information as the fourth edge image DP4;

[0081] Analyze the first edge image DP1 to obtain the blank missing information of the first edge image DP1, including the edge missing image and the edge crack image. Among them, the missing distance of the largest missing block in the edge missing image is LP1, and the farthest crack distance in the edge crack image is LQ1.

[0082] The missing distance of the largest missing block of the first edge image refers to the distance between the left edge of the back image information and the rightmost point of the largest missing block;

[0083] Analyze the second edge image DP2 to obtain the blank missing information of the second edge image DP2, including the edge missing image and the edge crack image. Among them, the missing distance of the largest missing block in the edge missing image is LP2, and the farthest crack distance in the edge crack image is LQ2.

[0084] Analyze the third edge image DP3 to obtain the blank missing information of the third edge image DP3, including the edge missing image and the edge crack image. Among them, the missing distance of the largest missing block in the edge missing image is LP3, and the farthest crack distance in the edge crack image is LQ3.

[0085] Analyze the fourth edge image DP4 to obtain the blank missing information of the fourth edge image DP4, including the edge missing image and the edge crack image. Among them, the missing distance of the largest missing block in the edge missing image is LP4, and the farthest crack distance in the edge crack image is LQ4.

[0086] When there are missing parts or cracks at the edges of the fire door core board blank, the effective use position of the edges of the fire door core board blank is reduced. If wet splitting is carried out according to the established wet splitting mode, defects will occur on one side of the board after wet splitting. Therefore, by detecting the distance of the missing parts or cracks and adjusting the clamping center line position according to the detection results, the pertinence of the wet splitting process is ensured, and the yield rate of the wet split products is improved.

[0087] Compare the missing distance LPe, e = 1, 2, 3, 4, of the largest missing block with the preset missing distance LPz of the largest missing block.

[0088] Compare the farthest crack distance LQf, f = 1, 2, 3, 4, in the edge crack image with the preset farthest crack distance LQz in the edge crack image.

[0089] If there is no LPe ≥ LPz and no LQf ≥ LQz, it is determined that the clamping center line position of the p-th fire door core board blank is located at L / 2 from the left edge of its front image, where L is the width of the p-th fire door core board blank.

[0090] If there is LPe ≥ LPz, it is determined that there is an effective missing distance.

[0091] If there is LQf ≥ LQz, it is determined that there is an effective crack distance.

[0092] By setting the preset missing distance and the preset farthest crack distance, small missing distances and small farthest crack distances are discarded, ensuring the rapidity and reasonableness of the wet splitting process.

[0093] If there exists LPe ≥ LPz, or there exists LQf ≥ LQz, then determine the clamping center line position of the p-th fire door core board blank according to the number of cases where there exists LPe ≥ LPz, or there exists LQf ≥ LQz.

[0094] If there exists LPe ≥ LPz and there does not exist LQf ≥ LQz, then calculate the center line deviation distance Wp according to the maximum value LPe’ among LP1, LP2, LP3, LP4, where e’ is one of 1, 2, 3, 4, and set

[0095] Wp = (LPe’ - LPz) × α, where α is the first calculation compensation parameter for the center line deviation distance Wp.

[0096] Compare the center line deviation distance Wp with the center line deviation safety distance Wpz.

[0097] If Wp ≥ Wpz, then determine that the p-th fire door core board blank cannot be effectively wet split.

[0098] If Wp < Wpz, then determine that the p-th fire door core board blank can be effectively wet split, and determine the clamping center line position of the p-th fire door core board blank according to the value of e’.

[0099] For the case of having a single valid blank missing information, determine the center line deviation distance according to the certainty of the single blank missing information, and compare the center line deviation distances, eliminating the fire door core board blanks that cannot be effectively wet split, ensuring the screening of the fire door core board blanks that can be reasonably wet split and reducing unnecessary processes.

[0100] If e’ = 1 or 4, then determine that the clamping center line position of the p-th fire door core board blank is located at L / 2 - Wp from the left edge of its front image.

[0101] If e’ = 2 or 3, then determine that the clamping center line position of the p-th fire door core board blank is located at L / 2 + Wp from the left edge of its front image.

[0102] For the first calculation compensation parameter α of the center line deviation distance, its value is related to the number of cases where there exists LPe ≥ LPz. If there is exactly one LPe ≥ LPz, then α = α1, where α1 is the base value of the first calculation compensation parameter for the center line deviation distance.

[0103] If there are two LPe ≥ LPz, and e = 1 or 4, or e = 2 or 3, then α = α1 × 1.2.

[0104] If there are two LPe ≥ LPz, and e = 1 or 2, or e = 1 or 3, or e = 2 or 4, or e = 4 or 3, then α = α1 × 0.95.

[0105] If there are three LPe≥LPz, then α = α1×0.95, or α = α1×1.2; where

[0106] The case of α = α1×0.95 includes

[0107] e = 1, 2 or 4, e’ = 2;

[0108] e = 2, 3 or 4, e’ = 4;

[0109] e = 1, 2 or 3, e’ = 1;

[0110] e = 1, 3 or 4, e’ = 3;

[0111] For other cases where there are three LPe≥LPz, α = α1×1.2.

[0112] If there are four LPe≥LPz, then α = α1×1.2.

[0113] For the case where there are multiple effective missing distances, according to the quantity and distribution of the effective missing distances, the value of the first calculation compensation parameter for the center line deviation distance is determined, which ensures the pertinence during the wet splitting process and improves the yield rate of the wet split products. In particular, for the case where multiple effective missing distances are on the same side, it indicates that the possibility of problems occurring on the single-side edge during the wet splitting process and subsequent processing is relatively large, so the value of the first calculation compensation parameter for the center line deviation distance is increased to ensure the rationality of the wet splitting. For the case where multiple effective missing distances are on different sides, if there are two effective missing distances, it indicates that there is a possibility of problems occurring on both sides during the wet splitting process and subsequent processing. Therefore, the value of the first calculation compensation parameter for the center line deviation distance is appropriately reduced to ensure the rationality of the wet splitting.

[0114] If there is no LPe≥LPz and there is LQf≥LQz, then according to the maximum value LQf’ among LQ1, LQ2, LQ3, LQ4, where f’ is one of 1, 2, 3, 4, calculate the center line deviation distance Wp, and set

[0115] Wp = (LQf’ - LQz)×β, where β is the second calculation compensation parameter for the center line deviation distance Wp

[0116] Compare the center line deviation distance Wp with the center line deviation safety distance Wpz

[0117] If Wp≥Wpz, then it is determined that the p-th fire door core board blank cannot be effectively wet split;

[0118] If Wp<Wpz, then it is determined that the p-th fire door core board blank can be effectively wet split, and the clamping center line position of the p-th fire door core board blank is determined according to the value of f’.

[0119] If f’ = 1 or 4, it is determined that the clamping center line position of the p-th fire door core board blank is located at L / 2 - Wp from the left edge of its front image;

[0120] If f’ = 2 or 3, it is determined that the clamping center line position of the p-th fire door core board blank is located at L / 2 + Wp from the left edge of its front image.

[0121] For the second calculation compensation parameter β of the center line deviation distance, its value is related to the number of LPf≥LPz. If there is exactly one LPf≥LPz, then β = β1, where β1 is the base value of the second calculation compensation parameter of the center line deviation distance;

[0122] If there are two LPf≥LPz, and f = 1 or 4, or f = 2 or 3, then β = β1×1.15;

[0123] If there are two LPf≥LPz, and f = 1 or 2, or f = 1 or 3, or f = 2 or 4, or f = 4 or 3, then β = β1×0.97.

[0124] If there are three LPf≥LPz, then β = β1×0.97, or β = β1×1.15; where,

[0125] The case of β = β1×0.97 includes,

[0126] f = 1, 2 or 4, f’ = 2;

[0127] f = 2, 3 or 4, f’ = 4;

[0128] f = 1, 2 or 3, f’ = 1;

[0129] f = 1, 3 or 4, f’ = 3;

[0130] For other cases where there are three LPf≥LPz, β = β1×1.15.

[0131] If there are four LPf≥LPz, then β = β1×1.15.

[0132] For the case where there are multiple effective crack distances, according to the quantity and distribution of the effective crack distances, the value of the second calculation compensation parameter for the center line deviation distance is determined, ensuring the pertinence during the wet splitting process and improving the yield rate of wet split products. In particular, for the case where multiple effective crack distances are on the same side, it indicates that there is a greater possibility of problems occurring on the single-sided edge during the wet splitting process and subsequent processing. Therefore, the value of the second calculation compensation parameter for the center line deviation distance is increased to ensure the rationality of wet splitting. For the case where multiple effective crack distances are on different sides, if there are two effective crack distances, it indicates that there is a possibility of problems occurring on both sides during the wet splitting process and subsequent processing. Therefore, the value of the second calculation compensation parameter for the center line deviation distance is appropriately reduced to ensure the rationality of wet splitting.

[0133] If there exists LPe ≥ LPz, and there exists LQf ≥ LQz, then according to the maximum value LQf’ among LQ1, LQ2, LQ3, LQ4, and the maximum value LPe’ among LP1, LP2, LP3, LP4, calculate the center line deviation distance Wp, and set

[0134] If LQf’ and LPe’ are on the same side of the center of the p-th fire door core board blank

[0135]

[0136] Compare the center line deviation distance Wp with the center line deviation safety distance Wpz;

[0137] If LQf’ and LPe’ are on different sides of the center of the p-th fire door core board blank

[0138] Wp = (Wp1 + Wp2) ÷ 2, Wp1 = (LPe’ - LPz) × α, Wp2 = (LQf’ - LQz) × β.

[0139] For the case where there are both effective crack distances and effective missing distances simultaneously, through the distribution of the effective crack distances and effective missing distances, calculate the center line deviation distance, ensuring the pertinence during the wet splitting process and improving the yield rate of wet split products.

[0140] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of the wet splitting device in the embodiment.

[0141] The wet splitting device 4 includes several groups of wet splitting units 41. For any wet splitting unit 41, it can perform wet splitting on a single fire door core board blank, and it includes

[0142] a rotating clamping module, on which a rotating shaft 422, a first telescopic rod, a first clamping assembly 424, and a second clamping assembly 423 are provided. Among them, the length of the first clamping assembly 424 is longer than that of the second clamping assembly 423;

[0143] The fixed clamping module is provided with equal third clamping components 433, fourth clamping components 432, and second telescopic rods 431 thereon.

[0144] During wet splitting, control the first telescopic rod to drive the first clamping component and the second clamping component to clamp one side of the fire door core board blank, and the second telescopic rod to drive the third clamping component and the fourth clamping component to clamp the other side of the fire door core board blank.

[0145] The edge of the first clamping component coincides with the position of the clamping center line. The distance between the first clamping component and the third clamping component is L01, and it is set that L01 = 3 cm.

[0146] After the clamping is completed, the rotating shaft rotates to complete wet splitting. The rotating direction is perpendicular to the end of the first clamping component and points to the side of the second clamping component.

[0147] The length of the first clamping component is longer than that of the second clamping component, which ensures reasonable force support during the wet splitting process and improves the yield of the wet-split products.

[0148] The above are only the preferred embodiments of the present invention and are not used to limit the present invention; for those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
