[0036] See also Figure 1-9 , the present invention provides embodiment 1:

[0037] See Figure 1 、 2 A composite flame retardant and fireproof wooden door preparation device includes a grinding device 1, which includes a base and a wooden door positioning mechanism 2, a wooden door grinding mechanism 3 and a wooden door storage mechanism 4 arranged above the base. The wooden door is positioned by the positioning mechanism and transferred to the wooden door grinding mechanism 3 for grinding and then transferred to the wooden door storage mechanism 4.

[0038] See Figure 3, the wooden door positioning mechanism 2 includes a first positioning plate 21 and a positioning frame 22. A first conveying groove 5 is provided on the front side of the first positioning plate 21. The front side of the first conveying groove 5 is open. The positioning frame 22 is horizontally slidably arranged in the first conveying groove 5. The thickness of the positioning frame 22 is less than the thickness of the wooden door. A door groove 6 for the wooden door to be inserted is provided in the middle of the positioning frame 22. When the wooden door is inserted into the door groove 6 and one side end face abuts against the inner wall of the first conveying groove 5, the positioning frame 22 is sleeved on the middle position of the thickness of the wooden door. A positioning component 7 for positioning the wooden door is provided in the positioning frame 22. The positioning component 7 is arranged within the four sides of the positioning frame 22. The positioning component 7 includes a pressing plate 71 and a connecting spring 72. A pressing plate groove 8 for the pressing plate 71 to slide in is provided on the inner wall of the positioning frame 22. The connecting spring 72 is arranged in the pressing plate groove 8. One end of the connecting spring 72 is fixedly connected to the inner wall of the pressing plate groove 8, and the other end is fixedly connected to the pressing plate 71. An inclined surface 9 is provided at one end of the pressing plate 71 located outside the pressing plate groove 8. The four side end faces of the wooden door are in contact with the four side inner walls of the door groove 6. When inserted into the door groove 6, it will slide the pressing plate 71 in the pressing plate groove 8 by abutting against the inclined surface 9 of the pressing plate 71. After the wooden door is inserted into the door groove 6, the four side pressing plates 71 will initially press and position the four sides of the wooden door.

[0039] Refer to Figure 3-5 , in order to make it easier for the wooden door to be inserted into the door groove 6 and obtain a stronger pressing force after insertion, a short rod 11 is provided on one side pressing plate 71 close to the column 10. A short rod groove 12 for the short rod 11 to be inserted is provided in the pressing plate groove 8. A pressurizing component 13 is provided in the short rod groove 12. The pressurizing component 13 includes a pressurizing plate 131 and a pressurizing spring 132. A blocking rod 14 for isolating the contact between the short rod 11 and the pressurizing plate 131 is provided on the inner wall of the short rod groove 12. A side groove 15 for the blocking rod 14 to slide in is provided on the inner wall of the short rod groove 12. A separating rod spring 17 connected to the blocking rod 14 is provided in the side groove 15. An abutting inclined surface 16 is provided on one side of the blocking rod 14 located in the short rod groove 12. When the wooden door is inserted into the door groove 6 and the pressing plate 71 is completely located in the pressing plate groove 8, the blocking rod 14 disengages from the abutment against the pressurizing plate 131. The pressurizing plate 131 will apply pressure to the pressing plate 71 under the action of the pressurizing spring 132, increasing the pressing force of the pressing plate 71 on the wooden door, making the wooden door fixed more firmly, and making it easier for the wooden door to be inserted into the door groove 6. Among them, the connecting spring 72 can use a spring 52 with a smaller elastic force, and the pressurizing spring 132 can use a spring 52 with a larger elastic force.

[0040] Refer to Figure 1 , 6, the wooden door grinding mechanism 3 includes a motor 31 and a grinding disc 32 fixed to the output end of the motor 31. A column 10 is provided on one side of the first positioning plate 21. The wooden door grinding mechanisms 3 are symmetrically arranged on the front and rear sides of the column 10. The motor 31 grinding mechanism is slidably arranged on the column 10 along the height direction of the column 10. A driving mechanism for driving the two groups of motor 31 grinding mechanisms to slide reciprocally on the column 10 is provided on the column 10;

[0041] Chutes 18 are symmetrically provided on the front and rear sides of the column 10. A sliding seat 19 is slidably arranged up and down in the chutes 18. A limiting groove 41 is provided on the inner wall of the sliding connection between the chutes 18 for the sliding seat 19. A limiting rod 42 that forms a sliding fit with the limiting groove 41 is provided on the side wall of the sliding seat 19 to ensure the stability of the sliding seat 19 during the sliding process. The motor 31 is fixed to the sliding seat 19. The output end of the motor 31 penetrates through the sliding seat 19 and extends to the grinding area 91 and then is fixedly connected to the grinding disc 32. The driving mechanism includes a double-headed motor 65 and a reciprocating screw rod 43. Horizontal edge plates 44 are provided on the front and rear sides of the top of the column 10. The reciprocating screw rod 43 is rotatably arranged between the base and the horizontal edge plates 44. The reciprocating screw rod 43 penetrates through the sliding seat 19 and forms a threaded fit with the sliding seat 19. The top end of the reciprocating screw rod 43 penetrates through the horizontal edge plate 44 and is connected with a linkage bevel gear 45 at the top end. The double-headed motor 65 is fixed to the top of the column 10 and driving bevel gears 46 meshing with the linkage bevel gear 45 are respectively fixed to the output ends of both heads. By driving the front and rear two groups of reciprocating screw rods 43 to rotate through the motor 31, the front and rear two groups of grinding discs 32 can be simultaneously driven to grind the two sides of the wooden door.

[0042] Refer to Figure 6 , 7 , in order to make the distance between the front and rear two groups of grinding discs 32 greater than the thickness of the wooden door so that the wooden door can enter, the front and rear two groups of grinding discs 32 located in the grinding area 91 are arranged oppositely. An adapter sleeve 47 is provided on one side of the grinding disc 32 connected to the output end of the motor 31. A connecting shaft 48 is provided at the output end of the motor 31. A shaft groove 49 for the sliding connection of the connecting shaft 48 is provided in the adapter sleeve 47. A spiral groove 50 is provided on the inner wall of the shaft groove 49. A short shaft 51 that cooperates with the spiral groove 50 is provided on the outer wall of the connecting shaft 48. A spring 52 is provided in the shaft groove 49. One end of the spring 52 is fixedly connected to the end of the connecting shaft 48, and the other end is fixed to the bottom inner wall of the shaft groove 49. In the initial state, the spring 52 tightens the grinding disc 32 and the connecting shaft 48. When the motor 31 starts to drive the connecting shaft 48 to rotate, under the action of centrifugal force, the short shaft 51 slides along the spiral groove 50 to the end of the spiral groove 50, causing the grinding disc 32 to slide towards the wooden door side and grind the wooden door, and also causing the grinding disc 32 to continuously exert a certain pressure on the wooden door. It should be noted that: in order to avoid generating torsion on the spring 52 when the connecting shaft 48 and the adapter sleeve 47 rotate relatively, an annular groove is provided on the bottom inner wall of the shaft groove 49, and a rotating disc 53 is rotatably arranged in the annular groove. One end of the spring 52 is fixed to the rotating disc 53.

[0043] Refer to Figure 3 、 6 、8, in order to intermittently convey the wooden door during the process of the wooden door grinding mechanism 3 moving up and down to grind the wooden door, a plurality of conveying rollers 55 are rotatably provided on the upper and lower inner walls of the first conveying groove 5 and the second conveying groove 54. The conveying rollers 55 are arranged uniformly along the sliding direction of the positioning frame 22. Rack bars 56 are provided on the outer walls of the upper and lower sides of the positioning frame 22. Inner gears 57 for meshing with the rack bars 56 at the upper and lower ends of the positioning frame 22 are provided on the upper and lower sides in the grinding area 91. External gears 58 are provided on the outside of the inner gears 57 on the column 10. A connecting rod 59 is rotatably provided on the column 10. One end of the connecting rod 59 extends into the grinding area 91 and is fixedly connected to the inner gear 57. The end of the connecting rod 59 away from the inner gear 57 is connected to the external gear 58 through a one-way bearing 60. A short rack bar 61 for meshing with the external gear 58 is provided on the side wall of the sliding seat 19. After the sliding seat 19 moves to drive the wooden door grinding mechanism 3 to complete one longitudinal formation of the wooden door grinding, the end rack bar 56 will engage with the external gear 58 once and the inner gear 57 will rotate once. Thus, through the cooperation of the inner gear 57 and the rack bar 56, the positioning frame 22 is conveyed once, facilitating the grinding and polishing of the wooden door at the next longitudinal position by the grinding disc 32. Among them, the one-way bearings 60 at the connection points of the upper and lower two groups of connecting rods 59 and the external gear 58 on the column 10 are arranged in the reverse direction, so that when the sliding seat 19 moves one longitudinal formation, the positioning frame 22 is intermittently conveyed once. It should be noted that: during the process of the grinding disc 32 moving through the sliding seat 19 and grinding the wooden door, the grinding disc 32 will not separate from the wooden door. It should also be noted that: the connecting rod 59 is in interference fit with the column 10 and a certain force needs to be applied to make it rotate, avoiding the movement of the positioning frame 22 during the grinding of the wooden door.

[0044] Refer to Figure 3 , a gap 62 for the rack bar 56 to be inserted is provided in the middle of the conveying roller 55. A positioning magnetic attraction 63 is provided on the inner wall of the first conveying groove 5. The positioning magnetic attraction 63 does not exceed the height of the conveying roller 55 to avoid affecting the conveying of the positioning frame 22 by the conveying roller 55. A matching magnetic attraction 64 for cooperating with the positioning magnetic attraction 63 is provided on the outer wall of the positioning frame 22. The matching magnetic attraction 64 is embedded to avoid affecting the conveying of the positioning frame 22 by the conveying roller 55. After the positioning magnetic attraction 63 and the matching magnetic attraction 64 attract each other, the rack bar 56 and the inner gear 57 are engaged, facilitating the determination of the starting time of the motor 31 and the double-headed motor 65. Among them, a hand-pulling groove 66 is provided on the outer end face of the positioning frame 22, facilitating the operator to pull the positioning frame 22 to the required position. It should be noted that: a positioning magnetic attraction 63 can also be provided on the inner wall of the first conveying groove 5 on the side away from the column 10, and a matching magnetic attraction 64 can also be provided on the side wall of the positioning frame 22, so that when the wooden door is clamped into the positioning frame 22, the positioning frame 22 is not likely to move.

[0045] Refer to Figure 2 、 3, the wooden door storage mechanism 4 includes a second positioning plate 401 and a wooden door storage cart 402. A second conveying groove 54 is provided on the second positioning plate 401. One end of the wooden door storage cart 402 is open, and the open end is communicated with the second conveying groove 54. The inner cavity wall of the wooden door storage cart 402 coincides with the inner wall of the positioning frame 22, facilitating the pushing of the wooden door in;

[0046] A grinding area 91 is provided inside the column 10. The first conveying groove 5, the grinding area 91 and the second conveying groove 54 are communicated. A cylinder 67 is provided on one side of the second positioning plate 401 away from the wooden door storage cart 402. When the positioning frame 22 is located in the second conveying groove 54, the cylinder 67 can push the wooden door in the positioning frame 22 into the inner cavity of the storage cart. In order to prevent the positioning frame 22 from moving during the process of pushing the wooden door into the storage cart, a positioning magnetic attraction 63 can also be provided on the inner wall of the second conveying groove 54 on the side away from the column 10, and a matching magnetic attraction 64 is also provided on the side wall of the positioning frame 22.

[0047] See Figure 3 , in addition, in order to make the pressure plate 131 lose the extrusion on the pressing plate 71 during the process of the cylinder 67 pushing the wooden door into the storage cart, a strong magnetic rod 68 is provided on the inner wall of the second conveying groove 54. A jack 69 for inserting the strong magnetic rod 68 is provided on the outer wall of one side of the positioning frame 22. After the positioning frame 22 is positioned by the positioning magnetic attraction 63 in the second conveying groove 54, one end of the strong magnetic rod 68 is inserted into the short rod groove 12 through the jack 69 and magnetically attracts the pressure plate 131, causing the pressure plate 131 to move a certain distance, making it easier to push the wooden door into the storage cart. After the wooden door in the positioning frame 22 is pushed into the storage cart, the pressing plate 71 will reset under the action of the connecting spring 72. At this time, the blocking rod 14 will also reset under the action of the blocking spring 52 and be in the position of separating the short rod 11 and the pressure plate 131 for the next use; it should be noted that: a dovetail groove 80 is provided on the back of the second positioning plate 401, and a dovetail rod matching the dovetail groove 80 is provided on one side of the storage cart. The storage cart can move to the required position through the cooperation of the dovetail rod and the dovetail groove 80; it should also be noted that: a partition rod 81 is rotatably provided on the open side of the storage cart. A torsion spring is connected to the hinge of the partition rod 81 and the storage cart. In the initial state, the torsion spring makes the partition rod 81 horizontally extend, only allowing the wooden door in the second conveying groove 54 to enter the storage cart and restricting the wooden door in the storage cart from sliding out of the storage cart.

[0048] See Figure 6 、 9, in order to clean the wooden door when it enters the second transfer groove 54, a cleaning component 82 is provided on the inner wall at the connection between the grinding area 91 and the second transfer groove 54. The cleaning component 82 includes a cleaning plate 821, a piston plate 822 and a piston box 823. On the side of the piston plate 822 close to the cleaning plate 821, there are multiple groups of air pipes 83. On the cleaning plate 821, there are pipe holes 84 for the air pipes 83 to pass through. On the piston plate 822, there is also a resisting rod 85. The end of the resisting rod 85 far from the piston plate 822 is fixedly connected to the cleaning plate 821. The piston box 823 is fixed on the inner walls of the grinding area 91 and the second transfer groove 54, and there is a piston cavity 86 on one side for the piston plate 822 to slide. Inside the piston cavity 86, there is a resisting spring 87 for abutting against the piston plate 822. One end of the resisting spring 87 is fixed on the inner wall of the piston cavity 86, and the other end is fixed on the end face of the piston plate 822. On the outer wall of the cleaning plate 821, there are wave grooves 88. On the outer wall of the sliding seat 19, there is a driving rod 89 for inserting into the wave grooves 88. On the column 10, there is a driving rod groove 89 for the driving rod 89 to slide. One side end face of the cleaning rod will be arranged to fit the wooden door (where a sponge or cotton cloth or other cleaning materials can be arranged on the side of the cleaning rod contacting the wooden door). During the movement of the sliding seat 19, the driving rod 89 will slide in the wave grooves 88 and drive the cleaning plate 821 to reciprocate. The cleaning plate 821 will abut against the resisting rod 85 and drive the piston plate 822 to move in the piston box 823, so as to continuously spray gas and cooperate with the cleaning plate 821 to clean the sawdust on the surface of the wooden door. It should be noted that: on the side of the piston box 823 far from the cleaning plate 821, air holes can be arranged, and one-way valves are arranged in the air holes, and only the gas in the second transfer groove 54 is allowed to be pumped into the piston box 823. One-way valves are also arranged in the air pipes 83, and only the gas in the piston box 823 is allowed to be sprayed towards the grinding area 91; it should also be noted that: the piston box 823 is fixed on the inner wall at the connection between the grinding area 91 and the second transfer groove 54.

[0049] Please refer to Figure 1-9 As shown, when the device is in use, the fireproof wooden door that has been sprayed with fireproof paint and left to stand for several days is inserted into the positioning frame 22 through the door groove 6, and the inner end face of the wooden door is made to fit the inner wall of the first transfer groove 5. During the process of the wooden door being inserted into the positioning frame 22, the pressing plate 71 will be completely slid into the pressing plate groove 8. At this time, the short rod 11 will abut against the abutting inclined surface 16 of the blocking rod 14 and drive the blocking rod 14 to completely slide into the side groove 15, so that the pressing spring 132 drives the pressing plate 131 to press the short rod 11, increasing the pressing force of the pressing plate 131 on the wooden door.

[0050] After the wooden door is positioned, the operator's certificate pulls the positioning frame 22 to the position where the positioning magnetic attraction 63 on the inner walls of the upper and lower sides of the first transfer groove 5 attracts the mating magnetic attraction 64 on the upper and lower sides of the positioning frame 22 by pulling the groove 66. At this time, the racks 56 on the upper and lower sides of the positioning frame 22 are exactly meshed with the internal gears 57 on the upper and lower sides in the grinding area 91. At this time, the double-headed motor 65 and the motor 31 can be driven. The motor 31 starts to drive the connecting shaft 48 to rotate. The rotation of the connecting shaft 48 will push the connecting sleeve 47 towards the wooden door side under the cooperation of the short shaft 51 and the spiral groove 50, so that the grinding disc 32 presses against the wooden door and performs grinding and polishing (both groups of motors 31 drive the grinding disc 32 to rotate clockwise). At the same time, the double-headed motor 65 drives the driving bevel gear 46 to rotate. The driving bevel gear 46 drives the linkage bevel gear 45 to rotate, thereby driving the reciprocating screw rod 43 to rotate, and then driving the sliding seat 19 to move on the column 10. During the downward movement of the sliding seat 19, the short rack 61 meshes with a group of external gears 58 above the column 10 and does not drive the internal gear 57 to rotate (due to the function of the one-way bearing 60). After the grinding disc 32 finishes grinding a longitudinal formation of the wooden door, the short rack 61 will mesh with a group of external gears 58 below and drive the internal gear 57 to rotate, thereby driving the positioning frame 22 to perform a feeding and conveying. The sliding seat 19 will move upward under the cooperation of the reciprocating screw rod 43 and the sliding seat 19. When the sliding seat 19 moves upward, the short rack 61 will not drive the internal gear 57 to rotate through a group of external gears 58 below the column 10. After the grinding disc 32 finishes grinding a longitudinal stroke of the wooden door back, the short rack 61 will mesh with a group of external gears 58 above the column 10 and drive the internal gear 57 to rotate, thereby feeding and conveying the positioning block for another stroke. This process repeats in a cycle.

[0051] When the wooden door is polished on one side and enters the second transfer groove 54, the wooden door will first pass through the cleaning component 82. When the wooden door passes through the cleaning components 82 on the front and rear sides, due to the movement of the sliding seat 19, the driving rod 89 will move along with it. The driving rod 89 will slide in the wave groove 88 and push the cleaning plate 821 to slide reciprocally. The reciprocating sliding of the cleaning plate 821 will clean the surface of the wooden door. At the same time, the air pipe 83 will continuously eject gas to clean the surface of the wooden door, so that the wooden door entering the second transfer groove 54 remains clean.

[0052] After the positioning frame 22 completely enters the second transfer groove 54 and is positioned with the positioning magnetic attraction 63 in the second transfer groove 54, the strong magnetic rod 68 will insert into the short rod groove 12 and attract the pressure plate 131. At the same time, the air cylinder 67 is started to push the wooden door in the positioning frame 22 into the storage vehicle. At this time, the pressing plate 71 is reset under the action of the connecting spring 72. The blocking rod 14 will be located in the side groove 15 again under the action of the blocking spring 52 to separate the pressure plate 131 from the short rod 11, facilitating the next use.
