Description

Technical Field

[0001] This invention relates to the field of fireproof board production, specifically a fireproof board making machine that reduces material loss. Background Technology

[0002] Fireproof boards, as the name suggests, are boards that are fireproof and can isolate fire sources. They are mainly made by coating different fireproof materials on the boards, which prevents fire from directly igniting the boards, thereby achieving the purpose of fire prevention.

[0003] Fireproof board production machines integrate raw material processing into finished product production. Through internal filling and coating devices, fire-retardant materials are evenly and stably coated onto the boards, improving the adhesion between the boards and the fire-retardant material. Furthermore, the machines enable mass production of fireproof boards, significantly increasing production efficiency. When fireproof board production machines on the market are coating the fireproof material, the material is quite viscous and contains various particles. This often causes blockages or excessive liquid accumulation when the fireproof material flows through the filter screen, resulting in the fireproof material overflowing from the filter screen. When the excess fireproof material accumulates for a long time, it will gradually dry and harden, leading to waste. Therefore, an improved device is needed to address these problems.

[0007] Specifically, the storage device includes an E-type connecting frame, a second return spring, a sealing head, a funnel, a storage cavity, a front plate, a hose, a support base plate, and a delivery pump. The storage cavity is fixedly installed inside the support base plate. The funnel is fixedly installed at the bottom of the storage cavity. The second return spring is fixedly installed inside the storage cavity and is located above the funnel. The sealing head is fixedly installed at the bottom of the second return spring and at the top of the sealing head. The front plate is fixedly installed at the bottom of the front end of the E-type connecting frame. The delivery pump is fixedly installed at the top of the front end of the storage cavity.

[0008] Specifically, the filter screen is fixedly installed at the top front end of the support base, the extension bracket is fixedly installed at both ends of the top of the filter screen, the second gear meshes with the rack, and the worm gear meshes with the worm.

[0009] Specifically, the movable support plate is slidably sleeved on the track rod, the bottom end of the movable support plate is in contact with the inner bottom end of the filter screen, the connecting pipe is fixedly connected to the bottom end of the hose, the support base and the support base plate are fixedly installed on the top of the conveyor roller, and the support base plate is located in front of the support base.

[0013] The beneficial effects of this invention are: First, the flow guiding mechanism, connected to an external motor via a worm gear, allows the worm gear to rotate. When the worm gear rotates, it drives the worm wheel to rotate simultaneously, causing the contact convex plate to pass from the bottom of the front plate. This moves the sealing head upwards from inside the funnel, allowing the fire-retardant liquid inside the collection chamber to flow into the filter screen. Simultaneously, the rotation of the worm wheel also drives the first and second rotating rods, causing the movable support plate to reciprocate inside the filter screen. This pushes away the viscous liquid settled at the bottom of the filter screen, preventing clogging. Furthermore, the movement of the movable support plate drives the second gear to move on the side of the rack, causing the stirring rod to rotate inside the filter screen, further agitating the liquid and improving its mixing uniformity.

[0014] Second, through the setting of the synchronization device, when the moving support plate moves to the limit position, it can also drive the limiting convex plate to squeeze the guide convex block to move into the interior of the first piston rod to the limit position, so that the absorption head at the bottom of the connecting pipe can approach the fireproof material accumulated at the bottom of the support base. At this time, through the interconnection of the delivery pump, hose and connecting pipe, when the delivery pump is started, it can absorb the fireproof material at the bottom of the support base. Moreover, the discharge port of the delivery pump is interconnected with the interior of the receiving cavity, so that the fireproof material can be recycled and material waste is reduced.

[0021] The storage device 2 includes an E-type connecting frame 36, a second return spring 37, a sealing head 38, a funnel 39, a storage cavity 40, a front plate 41, a hose 42, a support base plate 43, and a delivery pump 44. The storage cavity 40 is fixedly installed inside the support base plate 43. The funnel 39 is fixedly installed at the bottom of the storage cavity 40.

[0022] The filter screen 11 is fixedly installed at the front top of the support base 29, and the extension bracket 13 is fixedly installed at both ends of the top of the filter screen 11. The second gear 22 meshes with the rack 8, and the worm wheel 12 meshes with the worm 10. When the worm 10 rotates, it can drive the worm wheel 12 to rotate at the same time.

[0023] The movable support plate 18 is slidably sleeved on the track rod 7. The bottom end of the movable support plate 18 is in contact with the inner bottom end of the filter screen 11. The connecting pipe 27 is fixedly connected to the bottom end of the hose 42. The support base 29 and the support substrate 43 are fixedly installed on the top end of the conveying roller 4, and the support substrate 43 is located in front of the support base 29, so that the substrate 3 can pass through the bottom end of the support base 29 after receiving the fireproof coating.

[0024] The front end of the front plate 41 is located above the end of the worm gear 12 away from the extension bracket 13. The limiting protrusion 20 is aligned with the guide protrusion 28. The bottom end of the connecting pipe 27 is fixedly installed with the absorption head. The two ends of the movable support plate 18 are provided with holes and slots that are compatible with the track rod 7. The two ends of the contact protrusion 14 and the side ends of the guide protrusion 28 are all set at a 45° slope to improve the smoothness of the contact protrusion 14 when passing through the bottom end of the hose 42.

[0025] The push-button switch 35 is electrically connected to the delivery pump 44. A horizontal support rod is fixedly installed inside the receiving cavity 40, and the second reset spring 37 is fixedly installed below the horizontal support rod, which can support the second reset spring 37 to drive the sealing head 38 to reset.

[0026] The interior of the L-shaped air cylinder 26 is hollow, and a sealed cavity is formed between the first piston rod 25, the L-shaped air cylinder 26 and the second piston rod 30. The trigger plate 34 is vertically aligned with the push button switch 35. A limit rod is fixedly installed on the top of the limit guide rod 32, and the trigger plate 34 is slidably sleeved on the limit rod to prevent the trigger plate 34 from tilting.

[0027] Working principle: In use, first connect the worm gear 10 to the external output motor, then start the output motor to drive the worm gear 10 to rotate. At this time, external fireproof coating can be poured into the storage cavity 40. When the worm gear 10 rotates, it drives the worm wheel 12 to rotate simultaneously. When the worm wheel 12 rotates, it drives the contact convex plate 14 to contact the bottom end of the front plate 41. The two ends of the contact convex plate 14 are set at a 45° slope, which facilitates the connection and fitting of the contact convex plate 14 and the front plate 41. When the contact convex plate 14 passes the bottom end of the front plate 41, it squeezes the front plate 41 to move upward. When the front plate 41 moves, it drives the E-type connecting frame 36 and the sealing head 38 to move upward, causing the sealing head 38 to disengage from the inside of the funnel 39, resulting in the contents of the storage cavity 40 being exposed to the fire. The fire-retardant coating flows out from the bottom front end of the receiving cavity 40, and is vertically aligned with the top of the filter screen 11, allowing the fire-retardant coating to flow into the interior of the filter screen 11. At this time, when the worm gear 12 drives the contact convex plate 14 past the bottom end of the front plate 41, the elasticity of the second return spring 37 causes the sealing head 38 to move rapidly downwards into the funnel 39, thus preventing excessive outflow of the fire-retardant coating from the receiving cavity 40. Simultaneously, the worm gear 12 rotates, causing the rotating disk 15 to rotate. The rotation of the rotating disk 15 drives the first rotating rod 16 to rotate, and the rotation of the first rotating rod 16 drives the second rotating rod 17 to move cyclically, causing the moving support plate 18 to move inside the filter screen 11. The sliding support plate 18 is slidably fitted onto the track rod 7 through the slots at both ends, ensuring that the moving support plate 18 moves in a straight line while preventing it from falling off. At this time, the bottom end of the moving support plate 18 is in contact with the bottom end of the filter screen 11, which pushes the fire retardant coating deposited at the bottom end of the filter screen 11, allowing the fire retardant coating to flow downward through the filter screen 11 to the top of the substrate 3. At the same time, the moving support plate 18 moves, which also drives the second gear 22 to move on the front end of the rack 8, causing the second gear 22 to rotate simultaneously. When the second gear 22 rotates, it drives the first gear 21 to rotate, and when the first gear 21 rotates, it drives the third gear 24 to rotate simultaneously through the transmission belt 23. This allows the stirring rod 19 to rotate inside the movable support plate 18. When the stirring rod 19 rotates, it can perform cyclic stirring inside the filter screen 11, thereby further improving the mixing uniformity of the fire retardant coating. When the fire retardant coating drips onto the surface of the substrate 3, the conveying roller 4 can continuously transport the substrate 3 to the front end until the substrate 3, carrying the fire retardant coating, passes the bottom end of the support base 29. The gap between the bottom end of the support base 29 and the substrate 3 allows the support base 29 to limit the accumulation of excess fire retardant coating on the surface of the substrate 3 at the bottom end of the support base 29. At the same time, when the movable support plate 18 moves to its limit position, it drives the limiting protrusion 20 to squeeze the guide protrusion 28 and the first piston rod 25 into the L-shaped air cylinder 26.The gas inside the L-shaped air cylinder 26 is compressed. Simultaneously, as the gas inside the L-shaped air cylinder 26 is compressed, the connecting pipe 27 is forced downwards to its limit position, causing the absorber head at the bottom of the connecting pipe 27 to approach the substrate 3, thus facilitating the absorption of excess fire-retardant coating. At this point, when the connecting pipe 27 moves downwards to its limit position, it drives the limiting guide rod 32 to slide inside the support base 29, ensuring that the connecting pipe 27 moves in a straight line. Simultaneously, as the limiting guide rod 32 moves downwards, it causes the trigger plate 34 to contact the push-button switch 35. The push-button switch 35 is electrically connected to the delivery pump 44, allowing the delivery pump 44 to be started in advance. At the same time, as the limiting guide rod 32 continues to move downwards, it can stretch the length of the extension spring 33, allowing the limiting guide rod 32 to move downwards again while the trigger plate 34 contacts the push-button switch 35. Meanwhile, a [missing information - likely a device or mechanism] is fixedly installed on the top of the limiting guide rod 32. A limiting vertical rod is used, and the trigger plate 34 is slidably sleeved on the limiting vertical rod, ensuring that the trigger plate 34 slides up and down in a straight line, facilitating the reset of the trigger plate 34. At this time, the absorption head at the bottom of the connecting pipe 27 can absorb excess fireproof coating at the bottom of the support base 29. The connecting pipe 27 is connected to the hose 42, allowing the fireproof coating to be absorbed by the connecting pipe 27 and the hose 42. Simultaneously, the discharge end of the delivery pump 44 is interconnected with the inside of the receiving cavity 40, allowing the delivery pump 44 to promptly return the recovered fireproof coating to the inside of the receiving cavity 40, completing the fireproof coating recovery work. When the moving support plate 18 causes the limiting protrusion 20 to disengage from the guide protrusion 28, the elasticity of the first reset spring 31 can cause the connecting pipe 27 to slide upward, thereby causing the absorption head at the bottom of the connecting pipe 27 to move away from the base plate 3, and the trigger plate 34 to disengage from the button switch 35, completing the power-off operation of the delivery pump 44.

The trigger plate (34) is vertically aligned with the button switch (35). When the moving support plate (18) moves to the limit position, it drives the limiting convex plate (20) to squeeze the guide convex block (28) and the first piston rod (25) into the interior of the L-shaped air cylinder (26), compressing the interior of the L-shaped air cylinder (26). When the gas inside the L-shaped gas cylinder (26) is compressed, it compresses the connecting pipe (27) and moves it downward to its limit position, causing the absorption head at the bottom of the connecting pipe (27) to approach the substrate (3), thereby absorbing excess fire retardant coating. At this time, when the connecting pipe (27) moves downward to its limit position, it drives the limiting guide rod (32) to slide inside the support base (29). At the same time, during the downward movement of the limiting guide rod (32), it drives the trigger plate (34) to contact the button switch (35), and communicates with the inside of the receiving cavity (40) through the discharge end of the delivery pump (44), so that the delivery pump (44) promptly returns the recovered fire retardant coating to the inside of the receiving cavity (40).

2. The fireproof board making machine for reducing material loss according to claim 1, characterized in that: The storage device (2) includes a second return spring (37), a sealing head (38), a funnel (39), a front plate (41), and a support base plate (43). The storage cavity (40) is fixedly installed inside the support base plate (43). The funnel (39) is fixedly installed at the bottom of the storage cavity (40). The second return spring (37) is fixedly installed inside the storage cavity (40) and is located above the funnel (39). The sealing head (38) is fixedly installed at the bottom of the second return spring (37), and the E-type connecting bracket (36) is fixedly installed on the sealing head. At the top of (38), the front plate (41) is fixedly installed at the bottom front end of the E-type connecting frame (36). When the worm gear (12) rotates, it drives the contact convex plate (14) to contact the bottom end of the front plate (41). The two ends of the contact convex plate (14) are set at a 45° slope, so that the contact convex plate (14) and the front plate (41) are mated and matched. When the contact convex plate (14) passes the bottom end of the front plate (41), it squeezes the front plate (41) to move upward. When the front plate (41) moves, it drives the E-type connecting frame (36) and the sealing head (38) to move upward, so that the sealing head (38) is disengaged from the inside of the funnel (39).
