Description

Technical Field

[0001] This utility model relates to the field of fireproof board processing technology, and in particular to a fireproof board edge grinding device. Background Technology

[0002] Fire-resistant boards, also known as fire-resistant panels, are technically called thermosetting resin high-pressure laminate decorative panels. They are building materials that combine aesthetics and fire resistance. With their colorful surfaces and diverse textures, they not only beautify spaces but also possess excellent fire resistance, making them an ideal choice for home and public space decoration.

[0003] A search revealed a fireproof board edge grinding device with patent number "CN219747329U". This device uses several electric telescopic rods to adjust and reduce the distance between two rectangular frames, moves two sliders, and positions the edge of the fireproof board between two grinding machine bodies. Finally, it ensures that the two grinding machine bodies are in close contact with the edge of the fireproof board. However, during the grinding of the fireproof board, many debris particles are splashed out. If these debris lands on the joints of the electric telescopic rods, it can cause the rods to move poorly or become stuck. Furthermore, the debris can cause wear to the internal mechanical structure of the electric telescopic rods, especially when the debris contains hard particles. Therefore, this application proposes a fireproof board edge grinding device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fireproof board edge grinding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fireproof board edge grinding device includes a working plate, a U-shaped frame fixedly connected to the upper end of the working plate, two fixed plates fixedly connected to the upper end of the working plate, a reciprocating screw rotatably connected between the fixed plates, a nut threaded onto the reciprocating screw, two connecting rods fixedly connected to the side wall of the nut, a grinding disc mounted on the end of the connecting rod away from the nut, a fixing mechanism for fixing the fireproof board mounted on the U-shaped frame, a fixing rod fixedly connected to the side wall of the nut, a square plug fixedly connected to the end of the fixing rod away from the nut, a square plug cylinder fixedly connected to the upper end of the working plate, the square plug sliding and sealing within the square plug cylinder, an air bladder connected to the bottom end of the square plug cylinder via an air outlet pipe, an air blowing pipe connected to the upper end of the air bladder, two branch pipes connected to the air blowing pipe, nozzles connected to the branch pipes, an air inlet pipe connected to the side wall of the square plug cylinder, and the branch pipes fixedly penetrating the fixed plates.

[0007] Preferably, the fixing mechanism includes two square plates, two screws, and two throttles. The square plates are slidably mounted on the upper end of the U-shaped frame. The screws are threaded onto the side walls of the square plates and the U-shaped frame. The throttles are fixedly mounted on the screws, and the screws penetrate the side walls of the U-shaped frame. A guide mechanism for guiding the square plates is mounted on the U-shaped frame.

[0008] Preferably, the guiding mechanism includes two sliders, which are fixedly installed at the lower ends of the two square plates respectively. The upper end of the U-shaped frame is provided with a sliding groove, and the slider slides in the sliding groove.

[0009] Preferably, a one-way valve is installed in the air inlet pipe and the air outlet pipe, and a pressure valve is installed in the air blowing pipe.

[0010] Preferably, the lower end of the working plate is fixedly connected to four support legs.

[0011] Preferably, a motor is fixedly connected to the side wall of the fixing plate, the output shaft of the motor is fixedly connected to the reciprocating lead screw, and a number of ventilation holes are provided on the nut.

[0012] This utility model has the following beneficial effects:

[0013] 1. The rotation of the reciprocating screw causes the nut to move back and forth on the screw, which in turn drives the square plug to move back and forth inside the square plug cylinder via the fixed rod, thereby continuously inflating the airbag. When the pressure inside the airbag reaches the preset value, it will be sprayed out from the nozzle through the air blowing pipe and the diverting pipe to clean the debris generated on the reciprocating screw due to grinding, preventing the debris from affecting the movement of the nut, avoiding wear between parts, and preventing the grinding disc from continuously grinding the fireproof board in one place due to jamming.

[0014] 2. Because an inflation process is required over a period of time, the nozzle sprays air intermittently to clean the reciprocating leadscrew, avoiding over-cleaning or waste that might occur with continuous air spraying. Simultaneously, the sprayed air can clean the other side of the reciprocating leadscrew through the ventilation holes, improving the cleaning effect and preventing debris from accumulating in hard-to-reach areas.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A fireproof board edge grinding device includes a working plate 1, a U-shaped frame 8 fixedly connected to the upper end of the working plate 1, two fixed plates 2 fixedly connected to the upper end of the working plate 1, a reciprocating screw 3 rotatably connected between the fixed plates 2, a nut 4 threadedly connected to the reciprocating screw 3, two connecting rods 6 fixedly connected to the side wall of the nut 4, and a grinding disc 7 installed at the end of the connecting rod 6 away from the nut 4. It should be noted that a drive device for rotating the grinding disc 7 is installed inside the grinding disc 7, which is existing technology.

[0022] A fixing mechanism for fixing fireproof boards is installed on the U-shaped frame 8. The fixing mechanism includes two square plates 17, two screws 16 and two handles 24. The square plates 17 are slidably installed on the upper end of the U-shaped frame 8. The screws 16 are threaded on the square plates 17 and the side walls of the U-shaped frame 8. The handles 24 are fixedly installed on the screws 16, and the screws 16 penetrate the side walls of the U-shaped frame 8.

[0023] A guiding mechanism for guiding the square plates 17 is installed on the U-shaped frame 8. The guiding mechanism includes two sliders 20, which are fixedly installed at the lower ends of the two square plates 17 respectively. A groove 21 is provided at the upper end of the U-shaped frame 8, and the sliders 20 slide within the groove 21.

[0024] A fixing rod 5 is fixedly connected to the side wall of the nut 4. A square plug 22 is fixedly connected to the end of the fixing rod 5 away from the nut 4. It should be noted that the length of the transverse rod connecting the fixing rod 5 and the square plug 22 is greater than the depth of the square plug cylinder 9. This prevents the square plug cylinder 9 from blocking the movement of the fixing rod 5 when the square plug 22 moves back and forth inside the square plug cylinder 9, thus avoiding damage between parts and allowing the inflation operation to proceed smoothly.

[0025] A square plug 9 is fixedly connected to the upper end of the working plate 1. The square plug 22 slides in a sealed manner inside the square plug 9. It should be noted that the square plug 22 slides in a sealed manner inside the square plug 9. The nut 4 is fixedly connected to the square plug 22 through the fixing rod 5. Therefore, the sliding of the square plug 22 inside the square plug 9 also limits the nut 4 and prevents the nut 4 from shifting.

[0026] The bottom end of the square plug cylinder 9 is connected to an air bag 11 via an air outlet pipe 15. The upper end of the air bag 11 is connected to an air blowing pipe 12. Two diverter pipes 13 are connected to the air blowing pipe 12. A nozzle 14 is connected to the diverter pipe 13. An air inlet pipe 10 is connected to the side wall of the square plug cylinder 9. The diverter pipe 13 is fixedly connected through the fixing plate 2.

[0027] One-way valves are installed in the air inlet pipe 10 and the air outlet pipe 15. It should be noted that the function of the one-way valves in the air inlet pipe 10 and the air outlet pipe 15 is as follows: when the square plug 22 moves to the outside of the square plug cylinder 9, the one-way valve in the air inlet pipe 10 opens and the one-way valve in the air outlet pipe 15 closes, so that outside air is drawn into the square plug cylinder 9 through the air inlet pipe 10. At this time, the gas in the square plug cylinder 9 will not be discharged through the air outlet pipe 15. When the square plug 22 moves to the inner bottom end of the square plug cylinder 9, the one-way valve in the air outlet pipe 15 opens and the one-way valve in the air inlet pipe 10 closes, so that the gas in the square plug cylinder 9 is discharged into the airbag 11 through the air outlet pipe 15. At this time, outside air will not enter the square plug cylinder 9 through the air inlet pipe 10.

[0028] A pressure valve is installed inside the air blowing pipe 12. It should be noted that the function of the pressure valve inside the air blowing pipe 12 is that as the gas in the airbag 11 gradually increases, the pressure value inside the airbag 11 increases. When the pressure value reaches the preset value, the pressure valve inside the air blowing pipe 12 opens, allowing the gas in the airbag 11 to be instantly discharged through the air blowing pipe 12, thus cleaning the debris on the reciprocating lead screw 3.

[0029] Four support legs 23 are fixedly connected to the lower end of the work plate 1. A motor 18 is fixedly connected to the side wall of the fixed plate 2. The output shaft of the motor 18 is fixedly connected to the reciprocating lead screw 3. Several ventilation holes 19 are provided on the nut 4. It should be noted that the gas discharged from the nozzle 14 can flow to the other side of the reciprocating lead screw 3 through the ventilation holes 19, which can blow off the debris on the reciprocating lead screw 3 and prevent the debris from accumulating in the dead corner of the reciprocating lead screw 3.

[0030] In this invention, the fireproof board to be polished is placed on the upper end of the U-shaped frame 8. The handle 24 is rotated, causing the screw 16 to rotate. The screw 16 then moves the square plates 17 closer together, fixing the fireproof board in place. The motor 18 and the drive mechanism within the polishing disc 7 are then activated. The motor 18 drives the reciprocating screw 3 to rotate, causing the nut 4 to reciprocate along the screw 3. The nut 4 then drives the connecting rods 6 on both sides to reciprocate, thus causing the polishing disc 7 to reciprocate along the sidewall of the fireproof board while polishing, resulting in more even polishing of the fireproof board.

[0031] Meanwhile, nut 4 drives square plug 22 to reciprocate within square plug cylinder 9 via fixing rod 5. When square plug 22 moves to the outside of square plug cylinder 9, the one-way valve in air inlet pipe 10 allows outside air to enter square plug cylinder 9 only through air inlet pipe 10. When square plug 22 moves to the inner bottom of square plug cylinder 9, the one-way valve in air inlet pipe 10 allows gas in square plug cylinder 9 to be discharged into airbag 11 for storage only through air outlet pipe 15. As the gas in airbag 11 increases, the pressure in airbag 11 also increases. When the pressure in airbag 11 reaches a preset value, the pressure valve in air blowing pipe 12 opens, allowing gas in airbag 11 to be instantly discharged from air blowing pipe 12 into diverter pipe 13, and then discharged through nozzle 14 to reciprocating screw 3. At the same time, gas flows through ventilation hole 19 to the other side of reciprocating screw 3, causing debris on reciprocating screw 3 to be blown off.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
