DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] In one embodiment, see Figure 1 、 Figure 2 and Figure 5, a hot pressing device for strengthening composite flooring, comprising two vertical plates 1, a support plate 9 is provided between the vertical plates 1, a placement groove 8 is provided on the top of the support plate 9, a clamping mechanism 3 is provided inside the placement groove 8, and the clamping mechanism 3 is used to clamp the composite flooring. The side walls of the support plates 9 are fixed with symmetrically distributed rotating rods 10, and the end of the rotating rod 10 away from the support plates 9 is rotatably connected to a fixed block 11, and the fixed block 11 is connected to a driving mechanism 5, and the driving mechanism 5 is used to drive the fixed block 11 to move horizontally. The rotating rod 10 is connected to a flipping mechanism 4, and the flipping mechanism 4 is used to drive the support plates 9 to flip, and a top plate 2 is fixed on the side walls of one of the vertical plates 1, and a hot pressing mechanism 7 and a cooling mechanism 6 are provided at the bottom of the top plate 2. The hot pressing mechanism 7 is used for hot pressing molding of the composite flooring, and the cooling mechanism 6 is used for cooling the composite flooring after hot pressing molding.

[0027] After the paving is completed, the paving is completed, and the paving is completed. In this embodiment, when the composite floor is hot-pressed, the composite floor is placed in the placement groove 8 on the top of the support plate 9, and the composite floor is supported by the support plate 9. Then, the driving mechanism 5 drives the fixing block 11 to move horizontally, and the fixing block 11 drives the support plate 9 to move horizontally through the rotating rod 10 until the composite floor moves to the bottom of the hot-pressing mechanism 7. In the process of the composite floor moving to the bottom of the hot-pressing mechanism 7, the clamping mechanism 3 will automatically clamp and position the composite floor in the placement groove 8, thereby improving the stability of the composite floor during the hot-pressing forming process, avoiding the misalignment between the substrates, and ensuring the forming accuracy of the composite floor. When the composite floor moves to the bottom of the hot-pressing mechanism 7, the composite floor can be hot-pressed by the hot-pressing mechanism 7, wherein the hot-pressing mechanism 7 includes a pressing plate, a telescopic rod, a heating component and other structures. The pressing plate is heated by the heating component, and the pressing plate is driven downward by the telescopic rod to perform hot-pressing on the composite floor. The above is the existing technology and will not be described in detail here. After the hot pressing of the board is completed, the driving mechanism 5 drives the fixed block 11 to move back, and the fixed block 11 drives the composite floor to move back through the rotating rod 10 and the support plate 9. In the process of the composite floor moving back, the cooling mechanism 6 at the bottom of the top plate 2 will cool the composite floor, thereby reducing the cooling time of the composite floor and improving the molding efficiency of the composite floor. At the same time, it can also avoid the damage to the staff caused by the high temperature of the formed composite floor. When the cooling mechanism 6 cools the composite floor, the flipping mechanism 4 drives the support plate 9 to flip through the rotating rod 10, and the support plate 9 drives the formed composite floor to flip. When the support plate 9 rotates 180°, the clamping mechanism 3 automatically releases the clamping of the composite floor. At this time, the composite floor automatically falls off from the inside of the placement groove 8, thereby achieving the purpose of automatic unloading, eliminating manual intervention, avoiding the risk of scalding, and realizing the automatic operation of the composite floor from positioning, hot pressing to unloading, effectively reducing the time required for the entire hot pressing cycle of the composite floor, and improving the production efficiency of the composite floor.

[0028] See also Figure 6 The clamping mechanism 3 includes a first clamping plate 31 and a second clamping plate 32 that are symmetrically distributed and arranged inside the placement groove 8. A gas pressure rod 33 is provided on the side walls of the first clamping plate 31 and the second clamping plate 32. A gas pressure groove 36 that is adapted to the gas pressure rod 33 is provided on the inner wall of the placement groove 8. The gas pressure rod 33 extends into the gas pressure groove 36 and is slidably connected to the gas pressure groove 36. The ends of the gas pressure rods 33 are fixed with first elastic members 35. The other end of the first elastic member 35 is fixedly connected to the inner wall of the gas pressure groove 36. The gas pressure groove 36 is connected to an air cavity 34. The air cavity 34 is connected to a booster assembly. The booster assembly is used to increase the air pressure inside the air cavity 34. When hot pressing the composite floor, the composite floor is placed inside the placement groove 8. At this time, the first plywood 31 and the second plywood 32 are respectively located on the sides of the composite floor. Then the driving mechanism 5 drives the support plate 9 to move through the fixed block 11 and the rotating rod 10. During the movement of the support plate 9, the booster component automatically increases the air pressure inside the air cavity 34, thereby increasing the air pressure inside the air pressure groove 36 and pushing the air pressure rod 33. The air pressure rod 33 drives the first plywood 31 and the second plywood 32 to move toward the composite floor until the first plywood 31 and the second plywood 32 are tightly fitted with the side wall of the composite floor. At this time, the first plywood 31 and the second plywood 32 play a clamping and positioning role for the composite floor, which effectively improves the stability of the laminate floor during the hot pressing process. The first and second plates 31 and 32 are automatically reset under the action of the first elastic member 35. The first and second plates 31 and 32 no longer clamp the composite floor, and the composite floor automatically falls off from the placement slot 8, thereby achieving the purpose of automatic unloading, eliminating manual intervention, and avoiding the risk of burns. The first elastic member 35 can be a spring.

[0029] See also Figure 3 and Figure 4The booster assembly includes a first fixed plate 38 that is fixedly connected to the bottom of the support plate 9 and is symmetrically distributed. The first fixed plate 38 is penetrated by a first air pressure cylinder 39, and the first air pressure cylinder 39 is slidably connected to the first piston 311, and the first piston 311 is fixedly connected to a push rod 312. A guide cylinder 313 is fixed to the end of the first air pressure cylinder 39, and the push rod 312 passes through the end of the second air pressure cylinder 68 and the guide cylinder 313 and is slidably connected to the two. The first air pressure cylinder 39 is connected to the first air pipe 310, and the other end of the first air pipe 310 is connected to the air cavity 34. An extrusion plate 320 is fixed between the vertical plates 1, and the side wall of the extrusion plate 320 has an inclined surface 321 for squeezing the end of the push rod 312. The push rod 312 is connected to a fixing component and a reset component. The fixing component is used to fix the push rod 312, and when the fixing component no longer fixes the push rod 312, the reset assembly is used to reset the push rod 312; When the support plate 9 moves, the first fixed plate 38 at the bottom of the support plate 9 drives the first air cylinder 39 to move horizontally. The first air cylinder 39 drives the push rod 312 to move horizontally through the guide cylinder 313. When the push rod 312 moves to a certain position, the inclined surface 321 on the side wall of the extrusion plate 320 squeezes the push rod 312, so that the push rod 312 drives the first piston 311 to move inside the first air cylinder 39. The first piston 311 squeezes the gas inside the first air cylinder 39. The gas inside the first air cylinder 39 enters the air cavity 34 through the first air pipe 310, thereby increasing the air pressure inside the air cavity 34 and pushing the air pressure rod 33. When the extrusion plate 320 is pressed, the push rod 312 is pressed. When the degree of squeezing of the push rod 312 by the 20 pairs of push rods no longer changes, the first clamping plate 31 and the second clamping plate 32 just fit tightly against the side wall of the composite floor, and the fixing component just completes the fixation of the push rod 312, effectively improving the stability of the push rod 312, thereby ensuring the fixing effect of the first clamping plate 31 and the second clamping plate 32 on the composite floor, and avoiding the phenomenon of the composite floor accidentally falling off from the placement groove 8 during the flipping of the support plate 9. When the support plate 9 flips 180°, the fixing component no longer fixes the push rod 312, and the push rod 312 drives the first piston 311 to automatically reset under the action of the reset component, thereby reducing the air pressure inside the air cavity 34.

[0030] See also Figure 4 The reset component includes a baffle 315 fixedly connected to the push rod 312, and a second elastic member 314 is provided on the outside of the push rod 312. The two ends of the second elastic member 314 are respectively fixedly connected to the baffle 315 and the end of the guide cylinder 313; When the push rod 312 moves to a certain position, the inclined surface 321 on the side wall of the extrusion plate 320 will squeeze the push rod 312, and the push rod 312 baffle 315 will squeeze the second elastic member 314. The second elastic member 314 is in a compressed state. When the fixing component no longer fixes the push rod 312, the second elastic member 314 releases its elastic potential energy, thereby driving the push rod 312 to reset through the baffle 315, where the second elastic member 314 can be a spring.

[0031] See also Figure 2 and Figure 4 The fixing component includes a pin 317 that passes through the side wall of the guide cylinder 313. The pin 317 is connected to the outer wall of the guide cylinder 313 through a third elastic member 318. A pin groove 316 that is adapted to the pin 317 is provided on the side wall of the push rod 312. A magnet 319 is fixed to the end of the pin 317. A magnetic column 37 is fixed to the bottom of the top plate 2. The magnetic properties of the magnetic column 37 are opposite to those of the magnet 319. When the push rod 312 moves to a certain position, the inclined surface 321 on the side wall of the extrusion plate 320 will squeeze the push rod 312, so that the push rod 312 drives the first piston 311 to move inside the first air pressure cylinder 39. When the degree of extrusion of the push rod 312 by the extrusion plate 320 no longer changes, the pin 317 is exactly aligned with the pin groove 316 on the push rod 312. The pin 317 automatically enters the pin groove 316 under the action of the third elastic member 318. The third elastic member 318 can be a spring. At this time, the pin 317 fixes the push rod 312 through the pin groove 316, effectively improving the stability of the push rod 312. This ensures the fixing effect of the first clamping plate 31 and the second clamping plate 32 on the composite floor, and avoids the composite floor from accidentally falling off from the placement groove 8 during the flipping of the support plate 9. When the support plate 9 flips 180°, the flipping mechanism 4 stops driving the support plate 9 to rotate. At this time, the magnet 319 at the end of the pin rod 317 just moves upward. As the support plate 9 continues to move, when the magnet 319 moves to just below the magnetic column 37, the magnetic column 37 and the magnet 319 attract each other, and the magnet 319 drives the pin rod 317 to move upward, and then pulls the pin rod 317 out of the pin groove 316. The fixation of the pin rod 317 is lost, and the push rod 312 automatically resets.

[0032] See also Figure 3 and Figure 6The flip mechanism 4 includes a turntable 41 fixed to the outside of the rotating rod 10, and a plurality of grooves 43 distributed in a circumference are provided on the side wall of the turntable 41. The inside of the groove 43 is rotatably connected with a stopper 42, and one end of the stopper 42 is rotatably connected to the inner wall of the groove 43, and the other end of the stopper 42 extends to the outside of the groove 43. One side of the stopper 42 is connected to one of the side walls of the groove 43 through a fourth elastic member 44, and the other side of the stopper 42 is in contact with the other side wall of the groove 43. A support bar 45 is fixed between the vertical plates 1, and a first tooth group 46 and a second tooth group 47 are fixed at the bottom of the support bar 45, which can drive the turntable 41 to rotate by pushing the block, and there is a certain distance between the first tooth group 46 and the second tooth group 47; When the composite floor is placed in the placement groove 8, the driving mechanism 5 drives the support plate 9 to move through the rotating rod 10. During the movement of the support plate 9, the first tooth group 46 and the second tooth group 47 will squeeze the stopper 42, and the stopper 42 squeezes the fourth elastic member 44, and the turntable 41 does not rotate. The fourth elastic member 44 can be a spring. At this time, the turntable 41 does not drive the support plate 9 to rotate through the rotating rod 10, which ensures the stability of the support plate 9, so that the support plate 9 will only flip over when it moves back. When the composite floor is formed, the driving mechanism 5 drives the support plate 9 to move back through the rotating rod 10. During the movement of the support plate 9 back, the first tooth group 46 first squeezes the stopper 42, and the stopper 42 pushes the turntable 41, so that the turntable 41 can drive the support plate 9 to flip over through the rotating rod 10. When the support plate 9 rotates 180° When the first tooth group 46 and the second tooth group 47 are in the process of squeezing the push block 42, the turntable 41 stops rotating. At this time, the support plate 9 can move back in a horizontal state. During the process of the support plate 9 moving back in a horizontal state, the clamping mechanism 3 no longer clamps the composite floor, and the composite floor automatically falls from the placement groove 8. Then the second tooth group 47 squeezes the stopper 42, and the stopper 42 pushes the turntable 41, so that the turntable 41 can drive the support plate 9 to reset through the rotating rod 10. The arrangement of the first tooth group 46 and the second tooth group 47 enables the composite floor to automatically fall from the placement groove 8 during horizontal movement, rather than falling from the placement groove 8 during the flipping process of the support plate 9. This avoids the phenomenon of the composite floor being thrown out of the placement groove 8 due to inertia during the flipping process of the support plate 9, ensures the stability of the composite floor falling, and plays a protective role for the composite floor.

[0033] See also Figure 1 and Figure 2The driving mechanism 5 includes a limiting rod 53 fixedly connected to the vertical plate 1, and a first threaded rod 52 rotatably connected to the vertical plate 1. The limiting rod 53 passes through one of the fixed blocks 11 and is slidably connected thereto. The first threaded rod 52 passes through the other fixed block 11 and is threadedly connected thereto. A motor 51 is mounted on one of the vertical plates 1, and the output end of the motor 51 is fixedly connected to the end of the first threaded rod 52. When hot pressing the composite floor, the composite floor is placed in the placement groove 8 and the motor 51 is started. The motor 51 drives the first threaded rod 52 to rotate, and the threaded connection between the first threaded rod 52 and the fixed block 11 drives the support plate 9 to move, thereby realizing automatic transportation of the composite floor, making the entire hot pressing process of the composite floor automated, and effectively improving the hot pressing efficiency of the composite floor. The limiting rod 53 can limit the support plate 9 through the fixed block 11, thereby improving the stability of the support plate 9 when moving.

[0034] See also Figure 2 The cooling mechanism 6 includes a branch pipe 61 arranged horizontally below the top plate 2, and a plurality of air outlet holes 62 are provided at the bottom of the branch pipe 61. The branch pipe 61 is connected to a second air pipe 63, and the second air pipe 63 is connected to an air intake assembly for ventilating the interior of the second air pipe 63. After the hot pressing of the composite floor is completed, the support plate 9 drives the composite floor to move back. During the movement of the composite floor, the air intake assembly ventilates the inside of the branch pipe 61 through the second air pipe 63, and the gas is discharged through the air outlet 62 at the bottom of the branch pipe 61 and acts on the surface of the composite floor. As the composite floor moves back, the gas discharged from the branch pipe 61 will pass evenly from the top of the composite floor to cool the composite floor, which can ensure the uniformity of cooling of the composite floor and avoid excessive cooling in some areas, which will cause inconsistent shrinkage of the glue layer and even local debonding and bubbling.

[0035] See also Figure 7 The air intake assembly includes a second fixed plate 64 fixedly connected to the bottom of the top plate 2 and symmetrically distributed, a second air pressure cylinder 68 is passed through the second fixed plate 64, a second piston 69 is slidably connected to the second air pressure cylinder 68, the second piston 69 is fixedly connected to a threaded sleeve 610, a second threaded rod 613 threadedly connected to the threaded sleeve 610, the second threaded rod 613 passes through the end of the second air pressure cylinder 68 and is connected to a rotating component, the rotating component is used to drive the second threaded rod 613 to rotate, a limiting block 612 is fixed on the side wall of the threaded sleeve 610, and a limiting groove 611 adapted to the limiting block 612 is provided on the inner wall of the second air pressure cylinder 68, and the end of the limiting block 612 is located inside the limiting groove 611 and is slidably connected to the limiting groove 611; When the composite floor is hot-pressed, the support plate 9 drives the composite floor to move toward the bottom of the hot-pressing mechanism 7. During this process, the rotating component drives the second threaded rod 613 to rotate. The second threaded rod 613 drives the second piston 69 to move inside the second air pressure cylinder 68 through the threaded connection with the threaded sleeve 610. A negative pressure is formed inside the second air pressure cylinder 68, and then the external gas is extracted through the branch pipe 61 and the second air pipe 63, so that the gas is stored inside the second air pressure cylinder 68. When the composite floor is hot-pressed, the support plate 9 drives the composite floor to move back. During the process of the composite floor moving back, the rotating component drives the second threaded rod 613 to reverse. At this time, the second piston 69 squeezes the gas inside the second air pressure cylinder 68, and then the gas inside the second air pressure cylinder 68 can enter the branch pipe 61 through the second air pipe 63, thereby achieving the purpose of cooling the composite floor. The limiting groove 611 can limit the threaded sleeve 610 through the limiting block 612, which effectively improves the stability of the threaded sleeve 610 when moving.

[0036] See also Figure 7 The rotating component includes a gear 65 fixed to the end of the second threaded rod 613, a connecting rod 66 is fixed to the top of the fixed block 11, and a toothed plate 67 capable of meshing with the gear 65 is fixed to the top of the connecting rod 66; When the composite floor is hot-pressed, the fixed block 11 drives the support plate 9 to move through the rotating rod 10, and also drives the tooth plate 67 to move through the connecting rod 66. When the tooth plate 67 moves to a certain position, the tooth plate 67 engages with the gear 65, thereby driving the second threaded rod 613 to rotate. When the composite floor is hot-pressed, the fixed block 11 drives the tooth plate 67 to move back through the connecting rod 66. At this time, the engagement of the tooth plate 67 with the gear 65 can drive the second threaded rod 613 to reverse, thereby allowing the gas inside the second air pressure cylinder 68 to enter the branch pipe 61 through the second air pipe 63.

[0037] Working principle: When the composite floor is hot-pressed, the composite floor is placed inside the placement groove 8 on the top of the support plate 9, and the composite floor is supported by the support plate 9. Then, the support plate 9 is driven to move toward the bottom of the hot-pressing mechanism 7 through the threaded connection between the first threaded rod 52 and the fixed block 11. When the support plate 9 moves to a certain position, the inclined surface 321 on the side wall of the extrusion plate 320 squeezes the push rod 312, so that the push rod 312 drives the first piston 311 to move inside the first air cylinder 39. The first piston 311 squeezes the gas inside the first air cylinder 39. The gas inside the first air cylinder 39 enters the air cavity 34 through the first air pipe 310, thereby increasing the air pressure inside the air cavity 34 and pushing the air pressure rod 33. The air pressure rod When the pressing degree of the pushing rod 312 by the squeezing plate 320 no longer changes, the first plywood 31 and the second plywood 32 are in close contact with the side wall of the composite floor. At this time, the first plywood 31 and the second plywood 32 play a clamping and positioning role for the composite floor. When the pushing rod 312 moves to a certain position, the inclined surface 321 on the side wall of the squeezing plate 320 squeezes the pushing rod 312, so that the pushing rod 312 drives the first piston 311 to move inside the first air pressure cylinder 39. When the squeezing degree of the pushing rod 312 by the squeezing plate 320 no longer changes, the pin rod 317 automatically enters the pin groove 316, and the pin rod 317 presses the pushing rod 312 through the pin groove 316. The second threaded rod 613 is driven by the second clamping plate 69 to move inside the second air cylinder 68, and the second piston 69 squeezes the gas inside the second air cylinder 68, thereby making the second air cylinder 68 move. The gas inside the pressing cylinder 68 can enter the inside of the branch pipe 61 through the second air pipe 63, and the gas is discharged through the air outlet 62 at the bottom of the branch pipe 61 and acts on the surface of the lower composite floor. As the composite floor moves back, the gas discharged from the branch pipe 61 will evenly pass over the top of the composite floor to cool the composite floor. At the same time, it can also ensure the uniformity of cooling of the composite floor, avoiding excessive cooling in some areas, resulting in inconsistent shrinkage of the glue layer, and even local degumming and bubbling. After the composite floor is cooled, as the support plate 9 moves back, the first tooth group 46 first squeezes the stopper 42, and the stopper 42 pushes the turntable 41, so that the turntable 41 can drive the support plate 9 to flip through the rotating rod 10. When the support plate 9 rotates 180 degrees,The first tooth group 46 no longer squeezes the push block, and the turntable 41 no longer rotates. At this time, the magnet 319 at the end of the pin rod 317 just moves upward. As the support plate 9 continues to move, when the magnet 319 moves to just below the magnetic column 37, the magnetic column 37 and the magnet 319 attract each other, and the magnet 319 drives the pin rod 317 upward, thereby pulling the pin rod 317 out of the pin groove 316. Without the fixation of the pin rod 317, the push rod 312 automatically resets, the air pressure inside the air cavity 34 decreases, the first clamping plate 31 and the second clamping plate 32 no longer clamp the composite floor, and the composite floor automatically falls off from the placement groove 8, thereby achieving the purpose of automatic unloading. As the support plate 9 continues to move back, the second tooth group 47 squeezes the stopper 42, and the stopper 42 pushes the turntable 41, so that the turntable 41 can drive the support plate 9 to reset through the rotating rod 10.
