Description

Technical Field

[0001] The present invention relates to the technical field of adjustable conveying equipment, and more specifically to an adjustable conveying device for spraying liquid flame retardant on wood-based panels. Background Art

[0002] During the production process of wood-based panels, in order to improve their fire resistance performance, it is often necessary to spray liquid flame retardant on the panels. As a key link in the entire technological process, the performance of the conveying device directly affects the spraying effect of the flame retardant and the production efficiency. An adjustable conveying device can flexibly adapt to wood-based panels of different specifications and production requirements, ensuring that the liquid flame retardant is evenly and efficiently sprayed onto the surface of the panels, which is of great significance for improving the flame retardant quality of wood-based panels and the economic benefits of production enterprises.

[0003] When the conveying device transports wood-based panels, it is necessary to stably clamp the wood-based panels. Since the front and back sides of the wood-based panels have a large area, the front and back sides of the wood-based panels need to be sprayed with flame retardant. When spraying the flame retardant, it is necessary to adjust the position of the fixed wood-based panel. When adjusting, it is necessary to consider the friction generated by fixation and whether the wood-based panel is parallel. If the wood-based panel is not parallel, it will lead to uneven spraying, thereby affecting the spraying quality. Summary of the Invention

[0004] The purpose of the present invention is to provide an adjustable conveying device for spraying liquid flame retardant on wood-based panels, so as to solve the problem that when the conveying device transports wood-based panels, it is necessary to stably clamp the wood-based panels. Since the front and back sides of the wood-based panels have a large area, the front and back sides of the wood-based panels need to be sprayed with flame retardant. When spraying the flame retardant, it is necessary to adjust the position of the fixed wood-based panel. When adjusting, it is necessary to consider the friction generated by fixation and whether the wood-based panel is parallel.

Limiting sliding grooves are respectively opened on the inner walls of one side of the mounting frame close to each other. One end of a plurality of the fixed sliding rods away from each other respectively extends into the two limiting sliding grooves and is respectively slidably connected to the limiting sliding grooves.

[0013] Further, L-shaped fixing plates are respectively and fixedly installed on the inner walls of one side of the two special-shaped round plates close to each other. Limiting plates are respectively and fixedly installed at the tops of the two L-shaped fixing plates. A transmission block is fixedly sleeved on the corresponding fixed sliding rod.

[0014] Further, a spraying mechanism is arranged on the top of the mounting frame. The spraying mechanism includes a U-shaped mounting plate fixedly installed on the top of the mounting frame. A spraying machine is fixedly installed on the top of the U-shaped mounting plate. An E3F-20C1 / 20L infrared sensor is fixedly installed on the inner wall of the top of the U-shaped mounting plate.

[0015] Furthermore, two circular tubes are fixedly installed at the bottom of the spraying machine. On the inner walls of the mutually approaching sides of the two special-shaped circular plates, special-shaped hollow tubes are respectively and fixedly installed. At the ends of the two special-shaped hollow tubes, two spraying heads are respectively and fixedly installed. The bottom ends of the two circular tubes respectively penetrate through the C-shaped mounting plate and are respectively communicated with the two spraying heads close to the C-shaped mounting plate. A number of inclined slots are respectively formed on the mutually approaching sides of the number of spraying heads, and two connecting tubes are fixedly installed on the number of spraying heads.

C-shaped connecting pipes are fixedly installed on the two exhaust hoods. The bottom end of the exhaust pipe is communicated with the exhaust hood close to the C-shaped mounting plate.

[0019] The present invention has the following beneficial effects:

[0020] (1) For the adjustable conveying device for spraying liquid flame retardant on wood-based panels of the present invention, when in use, the wood-based panel is placed on the fixed sliding rod, and then the wood-based panel is pressed downwards so that the wood-based panel is located between the two groups of rotating rollers and is in contact with the two groups of rotating rollers. Then, according to the width of the wood-based panel, the bidirectional threaded rod is rotated. During the rotation of the bidirectional threaded rod, the distance between the two internally threaded arc-shaped sleeves is adjusted, and the two internally threaded arc-shaped sleeves are made to approach each other. The two internally threaded arc-shaped sleeves respectively drive the two special-shaped fixing plates to approach each other. The two special-shaped fixing plates simultaneously drive the two annular sliding plates to approach each other. The annular sliding plates drive the telescopic springs to approach each other. The telescopic springs drive the clamping plates to approach each other. Since the rotating rollers are in contact with the wood-based panel, at this time, when the annular sliding plates approach each other, the telescopic springs undergo compressive deformation. Correspondingly, the annular sliding plates will make the rotating rollers fit more tightly against the wood-based panel, improving the clamping force on the wood-based panel, and avoiding the wood-based panel from being uneven or shaking during transportation, resulting in uneven spraying and affecting the spraying quality. By rotating the bidirectional threaded rod, the distance between the annular sliding plates can be adjusted, so as to fix wood-based panels of different sizes, improving the flexibility of the device;

[0021] (2) For the adjustable conveying device for spraying liquid flame retardant on wood-based panels of the present invention, after fixing the wood-based panel, start the driving motor. The driving motor drives the first rotating shaft to rotate. The first rotating shaft drives several fixed sliding rods to rotate under the action of the second rotating shaft and the wide conveyor belt. The fixed sliding rods slide along the limit chute. The fixed sliding rods not only support the wood-based panel, but also drive the transmission block to move during the movement of the fixed sliding rods. During the movement of the transmission block, it will contact and push the wood-based panel to move towards the direction close to the driving motor. When the transmission block pushes the wood-based panel to move, the rotating roller will rotate following the movement of the wood-based panel, so as to improve the smoothness of the wood-based panel during movement. When the wood-based panel moves, it will contact the limit plate. Under the inclined surface limit action of the limit plate, the bottom of the wood-based panel will leave the fixed sliding rod and become suspended, and the flat part of the limit plate will keep the wood-based panel in a parallel state, which is convenient for subsequent uniform spraying on the wood-based panel;

[0022] (3) For the adjustable conveying device for spraying liquid flame retardant on wood-based panels of the present invention, when the wood-based panel moves below the E3F-20C1 / 20L infrared sensor, the E3F-20C1 / 20L infrared sensor will start the spraying machine. The spraying machine sprays the flame retardant into the spraying head through the circular tube. The flame retardant is transmitted to the spraying head below through the special-shaped hollow tube, and then several spraying heads will simultaneously spray the flame retardant onto the wood-based panel through several inclined grooves. Since the inclined grooves are inclined, the sprayed flame retardant just skims over the transmission block and is evenly distributed on the wood-based panel, which can effectively avoid the transmission block from hindering the distribution of the flame retardant. During the spraying process of the inclined grooves, the flame retardant will be sprayed on the top and bottom of the wood-based panel. When the wood-based panel leaves the E3F-20C1 / 20L infrared sensor, the spraying machine will stop spraying to avoid waste of the flame retardant;

[0023] (4) For the adjustable conveying device for spraying liquid flame retardant on wood-based panels of the present invention, during the continuous rotation of the first rotating shaft, it will drive several fan blades to rotate. The rotation of the fan blades will generate a suction force. The suction force will suck air from the outside through the air inlet holes and blow it into the heating box through the air outlet pipe. Heat will be generated in the heating box. When the air passes through the heating box, the heat will be sent into the exhaust pipe together. The air with heat will be input from the exhaust pipe into the exhaust hood. Since the two exhaust hoods are connected by a U-shaped connecting pipe, the two exhaust hoods will blow air synchronously. Just after the wood-based panel is sprayed, the exhaust hood will immediately blow the air with heat onto the wood-based panel to dry and evaporate the flame retardant on the wood-based panel, so that the flame retardant dries quickly and the drying rate of the flame retardant is improved. When the wood-based panel leaves the exhaust hood, the flame retardant sprayed on the wood-based panel will be completely dried. During the process of the transmission block driving the wood-based panel to move continuously, the wood-based panel will leave the two groups of rotating rollers, and the wood-based panel will fall to the bottom of the mounting rack under the action of gravity for collection.

[0024] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is an adjustable conveying device for spraying liquid flame retardant on wood-based panels, including a mounting bracket 1. Two annular sliding plates 2 are slidably installed through the mounting bracket 1. Two U-shaped fixing plates 3 are respectively fixedly installed on the front and back of the mounting bracket 1. Two special-shaped circular plates 4 are fixedly installed on a plurality of U-shaped fixing plates 3. It further includes:

[0038] An adjusting mechanism 5, the adjusting mechanism 5 includes a bidirectional threaded rod 502, an adjusting component, the bidirectional threaded rod 502 is used to drive the adjusting component to adjust, and a clamping component, the bidirectional threaded rod 502 is used to drive the clamping component to clamp;

[0039] The adjusting component includes special-shaped fixing plates 501 respectively fixedly installed on two annular sliding plates 2. A bidirectional threaded rod 502 is slidably installed through the two special-shaped fixing plates 501. Two internally threaded arc-shaped sleeves 503 are respectively fixedly installed on one side of the two special-shaped fixing plates 501 close to each other. The bidirectional threaded rod 502 is threadedly connected to a plurality of internally threaded arc-shaped sleeves 503;

[0040] The clamping assembly includes two telescopic springs 504 fixedly installed on the side where the two annular slides 2 are close to each other, two clamping plates 505 are fixedly installed on the ends where the two clamping plates 505 are close to each other, and two sliding rods 506 are fixedly installed on the sides where the two clamping plates 505 are away from each other, and the ends where the several sliding rods 506 are away from each other slide and extend into the two annular slides 2 respectively.

[0041] like Figure 3 As shown, a plurality of special-shaped round rods 507 are fixedly mounted on the sides of the two clamping plates 505 close to each other, and rotating rollers 508 are rotatably sleeved on the plurality of special-shaped round rods 507 .

[0042] Since the rotating roller 508 is in contact with the artificial board, the telescopic spring 504 is compressed and deformed when the annular slides 2 approach each other. The corresponding annular slides 2 will make the rotating roller 508 closer to the artificial board, thereby increasing the clamping force of the artificial board and preventing the artificial board from being non-parallel or shaking during transportation.

[0043] like Figure 1 and Figure 3 As shown, a driving mechanism 6 is provided on the front of the mounting frame 1, and the driving mechanism 6 includes a driving motor 601 fixedly installed on the front of the mounting frame 1, a rotating shaft 1 602 is rotatably installed on the mounting frame 1, and the front end of the rotating shaft 1 602 is fixedly connected to the driving motor 601, and a rotating shaft 2 603 is rotatably installed on the mounting frame 1, and two wide conveyor belts 604 are sleeved on the rotating shaft 1 602 and the rotating shaft 2 603.

[0044] After the artificial board is fixed, the driving motor 601 is started, and the driving motor 601 drives the rotating shaft 1 602 to rotate. The rotating shaft 1 602 drives a plurality of fixed sliding rods 606 to rotate under the action of the rotating shaft 2 603 and the wide conveyor belt 604 .

[0045] like Figure 3 As shown, a plurality of fixed slide bars 606 are fixedly installed on the two wide conveyor belts 604, and limiting slide grooves 605 are respectively provided on the inner wall of the side close to each other of the mounting frame 1, and the ends of the plurality of fixed slide bars 606 that are away from each other respectively extend into the two limiting slide grooves 605 and are respectively slidably connected with the limiting slide grooves 605.

[0046] The fixed slide bar 606 slides along the limiting slide groove 605, and the fixed slide bar 606 not only supports the artificial board.

[0047] like Figure 5 As shown, L-shaped fixing plates 607 are fixedly installed on the inner walls of the two special-shaped circular plates 4 on the side close to each other, and limiting plates 608 are fixedly installed on the top ends of the two L-shaped fixing plates 607. Transmission blocks 609 are fixedly sleeved on the corresponding fixed slide rods 606.

[0048] During the movement of the fixed sliding rod 606, the transmission block 609 will also be driven to move. During the movement of the transmission block 609, it will contact and push the wood-based panel to move towards the direction of the driving motor 601. When the transmission block 609 pushes the wood-based panel to move, the rotating roller 508 will rotate following the movement of the wood-based panel, so the smoothness of the wood-based panel during movement can be improved. When the wood-based panel moves, it will contact the limiting plate 608. Under the limiting effect of the inclined surface of the limiting plate 608, the bottom of the wood-based panel will leave the fixed sliding rod 606 and become suspended, and correspondingly, the flat part of the limiting plate 608 will keep the wood-based panel in a parallel state, which is convenient for subsequent uniform spraying of the wood-based panel.

[0049] As Figure 4 shown, a spraying mechanism 7 is provided at the top of the mounting frame 1. The spraying mechanism 7 includes a U-shaped mounting plate 701 fixedly installed at the top of the mounting frame 1. A spraying machine 702 is fixedly installed at the top of the U-shaped mounting plate 701. An E3F-20C1 / 20L infrared sensor 7021 is fixedly installed on the inner wall of the top of the U-shaped mounting plate 701.

[0050] When the wood-based panel moves below the E3F-20C1 / 20L infrared sensor 7021, the E3F-20C1 / 20L infrared sensor 7021 will start the spraying machine 702.

[0051] As Figure 4 and Figure 6 shown, two circular tubes 703 are fixedly installed at the bottom of the spraying machine 702. On the inner walls of the mutually approaching sides of the two special-shaped circular plates 4, special-shaped hollow tubes 704 are respectively fixedly installed. The ends of the two special-shaped hollow tubes 704 are respectively fixedly installed with two spraying heads 705. The bottom ends of the two circular tubes 703 respectively penetrate through the U-shaped mounting plate 701 and are respectively communicated with the two spraying heads 705 located near the U-shaped mounting plate 701. A number of inclined grooves 706 are respectively opened on the mutually approaching sides of the number of spraying heads 705. Two connecting tubes 707 are fixedly installed on the number of spraying heads 705.

[0052] The spraying machine 702 sprays the flame retardant into the spraying heads 705 through the circular tubes 703. The flame retardant is transmitted to the lower spraying heads 705 through the special-shaped hollow tubes 704. Then, the number of spraying heads 705 will simultaneously spray the flame retardant onto the wood-based panel through the number of inclined grooves 706. Since the inclined grooves 706 are inclined, the sprayed flame retardant just skims over the transmission block 609 and is evenly distributed on the wood-based panel.

[0053] As Figure 8As shown in the figure, a drying mechanism 8 is provided on the first rotating shaft 602. The drying mechanism 8 includes a wind box 801 rotatably sleeved on the first rotating shaft 602. The front of the wind box 801 is fixedly connected to the special-shaped circular plate 4. A plurality of fan blades 802 are fixedly installed on the first rotating shaft 602. An air inlet hole 803 is formed in the front of the wind box 801, and the air inlet hole 803 penetrates through the corresponding special-shaped circular plate 4.

[0054] During the continuous rotation of the first rotating shaft 602, a plurality of fan blades 802 will be driven to rotate. The rotation of the fan blades 802 will generate a suction force, and the suction force will suck in air from the outside through the air inlet hole 803.

[0055] As Figure 7 shown in the figure, an air outlet pipe 804 is fixedly installed on the left side of the wind box 801, and a heating box 805 is fixedly installed on the back of the mounting frame 1. The top end of the air outlet pipe 804 communicates with the heating box 805.

[0056] During the continuous rotation of the first rotating shaft 602, a plurality of fan blades 802 will be driven to rotate. The rotation of the fan blades 802 will generate a suction force, and the suction force will suck in air from the outside through the air inlet hole 803 and blow the air into the heating box 805 through the air outlet pipe 804, and heat will be generated in the heating box 805.

[0057] As Figure 6 shown in the figure, an exhaust pipe 806 is fixedly installed on the top of the heating box 805. Two exhaust hoods 807 are arranged in the mounting frame 1. A U-shaped connecting pipe 808 is fixedly installed on the two exhaust hoods 807. The bottom end of the exhaust pipe 806 communicates with the exhaust hood 807 close to the U-shaped mounting plate 701.

[0058] When the air passes through the heating box 805, the heat will be sent into the exhaust pipe 806 together. The air with heat will be input from the exhaust pipe 806 into the exhaust hood 807. Since the two exhaust hoods 807 communicate with each other through the U-shaped connecting pipe 808, the two exhaust hoods 807 will blow air synchronously. Immediately after the artificial board is just sprayed, the exhaust hood 807 will blow the air with heat onto the artificial board, drying and evaporating the flame retardant on the artificial board, making the flame retardant dry quickly, and improving the drying rate of the flame retardant. When the artificial board leaves the exhaust hood 807, the flame retardant sprayed on the artificial board will be completely dry. During the process of the driving block 609 driving the artificial board to move continuously, the artificial board will leave the two groups of rotating rollers 508, and the artificial board will fall to the bottom of the mounting frame 1 under the action of gravity for collection.

[0059] When in use, the artificial board is placed on the fixed slide bar 606, and then the artificial board is pressed downward so that the artificial board is located between the two groups of rotating rollers 508 and contacts the two groups of rotating rollers 508, and then the bidirectional threaded rod 502 is rotated according to the width of the artificial board. During the rotation process, the bidirectional threaded rod 502 adjusts the distance between the two groups of internal threaded arc sleeves 503 and makes the two groups of internal threaded arc sleeves 503 approach each other. The two groups of internal threaded arc sleeves 503 respectively drive the two special-shaped fixed plates 501 to approach each other, and the two special-shaped fixed plates 501 simultaneously drive the two annular The slide plates 2 are close to each other, the annular slide plates 2 drive the telescopic springs 504 to move closer to each other, and the telescopic springs 504 drive the clamping plates 505 to move closer to each other. Since the rotating rollers 508 are in contact with the artificial board, the telescopic springs 504 are compressed and deformed when the annular slide plates 2 are close to each other. The corresponding annular slide plates 2 will make the rotating rollers 508 closer to the artificial board, thereby improving the clamping force on the artificial board and preventing the artificial board from being non-parallel or shaking during transportation, resulting in uneven spraying and affecting the spraying quality. The distance between the annular slide plates 2 can be adjusted by rotating the bidirectional threaded rod 502. After the artificial board is fixed, the drive motor 601 is started, and the drive motor 601 drives the shaft 1 602 to rotate. The shaft 1 602 drives a plurality of fixed slide bars 606 to rotate under the action of the shaft 2 603 and the wide conveyor belt 604. The fixed slide bars 606 slide along the limiting slide groove 605. The fixed slide bars 606 not only support the artificial board, but also drive the transmission block 609 to move during the movement of the fixed slide bars 606. The transmission block 609 During the movement, the artificial board will be contacted and pushed to move in the direction close to the driving motor 601. When the transmission block 609 pushes the artificial board to move, the rotating roller 508 will rotate along with the movement of the artificial board, thereby improving the smoothness of the movement of the artificial board. When the artificial board moves, it will contact the limiting plate 608. Under the limiting effect of the inclined surface of the limiting plate 608, the bottom of the artificial board will leave the fixed slide bar 606 and become suspended. The corresponding flat part of the limiting plate 608 will keep the artificial board in a parallel state, which is convenient for subsequent uniform spraying of the artificial board.

[0060] When the wood-based panel moves below the E3F-20C1 / 20L infrared sensor 7021, the E3F-20C1 / 20L infrared sensor 7021 will activate the spraying machine 702. The spraying machine 702 sprays the flame retardant into the spraying head 705 through the circular tube 703. The flame retardant is transmitted to the lower spraying head 705 through the special-shaped hollow tube 704. Then, several spraying heads 705 will simultaneously spray the flame retardant onto the wood-based panel through several inclined grooves 706. Since the inclined grooves 706 are inclined, the sprayed flame retardant just skims over the transmission block 609 and is evenly distributed on the wood-based panel, effectively avoiding the transmission block 609 from hindering the distribution of the flame retardant. During the spraying process of the inclined grooves 706, the flame retardant will be sprayed on the top and bottom of the wood-based panel. When the wood-based panel leaves the E3F-20C1 / 20L infrared sensor 7021, the spraying machine 702 will stop spraying to avoid waste of the flame retardant. During the continuous rotation of the first rotating shaft 602, several fan blades 802 will be driven to rotate. The rotation of the fan blades 802 will generate a suction force. The suction force will suck in air from the outside through the air inlet holes 803 and blow the air into the heating box 805 through the air outlet pipe 804. Heat will be generated in the heating box 805. When the air passes through the heating box 805, the heat will be sent into the exhaust pipe 806 together. The air with heat will be input into the exhaust hood 807 from the exhaust pipe 806. Since the two exhaust hoods 807 are connected by a U-shaped connecting pipe 808, the two exhaust hoods 807 will blow air synchronously. Immediately after the wood-based panel is sprayed, the exhaust hood 807 will blow the air with heat onto the wood-based panel to dry and evaporate the flame retardant on the wood-based panel, making the flame retardant dry quickly and improving the drying rate of the flame retardant. When the wood-based panel leaves the exhaust hood 807, the flame retardant sprayed on the wood-based panel will be completely dry.
