DETAILED DESCRIPTION

[0049] The plywood rapid cooling device of the present invention will be described in more detail below with reference to the accompanying drawings and through specific embodiments.

[0050] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0051] See also Figure 1-Figure 8, a plywood rapid cooling device of this embodiment can make the plywood be evenly supported in the middle position of the cooling chamber 2 and cool the plywood quickly by passing the cold air from the bottom of the plywood and then from the top of the plywood, thereby improving the cooling efficiency of the plywood, ensuring the consistency of the cooling process, improving the quality of the final product, realizing the automatic loading and unloading and positioning of the plywood and the sealing function during cooling, reducing manual intervention, improving the automation level of the production line, and avoiding the plywood after hot pressing from scalding the operator, thereby increasing the safety of plywood production. In this embodiment, it mainly includes a movable device housing 1 arranged on the side of the hot press. The device housing 1 is a rectangular box with an opening on the front side, and a first slide rail 8 is arranged on the ground on both sides of the bottom end of the device housing 1. The device housing 1 is slidably arranged on the first slide rail 8, and a first screw 9 is rotatably arranged in the middle of the first slide rail 8, and the first screw 9 is threadedly connected to the device housing 1. The first screw 9 is connected to an external control unit. After the plywood is hot-pressed, the hot press is opened. When the plywood needs to be cooled, the control unit drives the first lead screw 9 to rotate so that the device housing 1 is close to the hot press.

[0052] To achieve cooling of the plywood, see Figure 1-Figure 6 In this embodiment, multiple groups of cooling chambers 2 are horizontally arranged in the vertical direction inside the device housing 1. An exhaust cavity 10 is provided on the rear side of the device housing 1, and an exhaust port 11 is provided at the top of the exhaust cavity 10. An exhaust groove 12 connected to the exhaust cavity 10 is horizontally provided on the upper part of the rear wall of the cooling chamber 2. At least one pressure sensor 13 is fixedly arranged in the middle position of the rear wall of the cooling chamber 2 below the exhaust groove 12. Multiple groups of air inlet cavities 14 respectively adapted to the corresponding cooling chambers 2 are provided on the inner wall of the exhaust cavity 10 below the exhaust groove 12, and an air inlet chamber 15 is fixedly arranged on the side of the device housing 1. An air cooler 4 connected to the corresponding cooling chamber 2 is fixedly arranged on the rear side of the device housing 1. The air cooler 4 is a mature prior art and will not be described in detail here. The air inlet chamber 15 is connected to the air outlet of the air cooler 4, and the air inlet chamber 14 passes through the side wall of the device housing 1 and is connected to the air inlet chamber 15. An air inlet groove 16 is horizontally opened on the rear wall of the cooling chamber 2 below the pressure sensor 13 , and the air inlet groove 16 is communicated with the corresponding air inlet cavity 14 .

[0053] The air cooler 4 is controlled to work, and the refrigerated air is conveyed to the air inlet cavity 14 through the air inlet chamber 15. At this time, the gas in the air inlet cavity 14 enters the cooling chamber 2 through the air inlet groove 16. At this time, the cold air bypasses from below one end of the plywood and returns from above the other end of the plywood. At this time, the cold air takes away the heat of the plywood and enters the exhaust cavity 10 through the exhaust groove 12, and is discharged from the exhaust port 11. In this way, the plywood is cooled quickly, the cooling efficiency of the plywood is improved, the consistency of the cooling process is ensured, and the quality of the final product is improved.

[0054] In order to achieve the positioning of the plywood, in this embodiment, see Figure 2-Figure 6 , a guide mechanism 3 for supporting the plywood is arranged inside the cooling chamber 2. The guide mechanism 3 includes two driving rollers 31 which are horizontally rotatably arranged in the middle position of the front side of the cooling chamber 2, and the two driving rollers 31 are symmetrically arranged up and down. After the plywood enters the cooling chamber 2, it first contacts the driving roller 31, and enters the cooling chamber 2 from the middle position of the driving roller 31. The ends of the driving roller 31 penetrate the side wall of the cooling chamber 2, and the ends of the driving roller 31 are fixedly provided with a first gear 32. Two winding rollers 33 are rotatably arranged in the cooling chamber 2 inside the driving roller 31, and the winding rollers 33 are symmetrically arranged up and down. After passing through the driving roller 31, the plywood passes through the middle position of the winding roller 33. The ends of the winding roller 33 penetrate the side wall of the cooling chamber 2, and the ends of the winding roller 33 are fixedly provided with a winding spring 34. A rolling cloth 35 is horizontally arranged inside the cooling chamber 2, and both ends of the rolling cloth 35 are wound on the corresponding rolling roller 33. When the plywood passes through the middle position of the roller 33, the plywood presses against the cloth 35 to overcome the resistance of the coil spring 34 and unrolls from the roller 33, so that the plywood is brought to the rear of the cooling chamber 2. At least one group of guide rollers 36 is rotatably arranged in the cooling chamber 2 behind the roller 33, and each group of guide rollers 36 is provided with two guide rollers 36 and are symmetrically arranged up and down. After the plywood carries the cloth 35 through the middle position of the roller 33, it moves to the rear side through the middle position of the guide roller 36. At this time, the guide roller 36 squeezes the plywood and guides the plywood until the plywood abuts the cloth 35 against the pressure sensor 13, and at this time, the pressure sensor 13 feeds back a signal to the outside.

[0055] The two first gears 32 corresponding to each cooling chamber 2 are meshed and connected with each other, a pulley 37 is coaxially fixedly arranged on the outer side of the first gear 32 on the upper side, and a belt 38 is sleeved on each adjacent pulley 37. A first motor 39 is fixedly arranged on the side of the equipment housing 1, and the driving end of the first motor 39 is connected to the corresponding pulley 37 through the belt 38. The first motor 39 is driven to work, and the corresponding pulley 37 is driven to rotate through the belt 38, so that all the first gears 32 are rotated synchronously through the belt 38, and then the driving roller 31 is rotated slowly. When the plywood passes through the middle position of the driving roller 31, the driving roller 31 squeezes the plywood and drives the plywood to move. After the pressure sensor 13 feedbacks the signal, the first motor 39 stops working.

[0056] To achieve automatic opening of the hatch, see Figure 2 and Figure 3, a liftable door 5 is provided on the front side of the device housing 1. The door 5 is provided with a plurality of vertical grooves vertically relative to the side of the device housing 1. Cold air passes through the vertical grooves from the front end of the plywood around to the top of the plywood. First slide grooves 17 are vertically provided at both ends of the front side of the device housing 1. The door 5 is a U-shaped structure and both ends of its open end slide in the corresponding first slide grooves 17. Racks 18 are vertically fixed on both sides of the door 5, and first bidirectional motors 19 are fixed on both sides of the top of the device housing 1. A second gear 20 meshing with the corresponding rack 18 is fixed on the output end of the first bidirectional motor 19.

[0057] When the device housing 1 moves, the first bidirectional motor 19 is driven to work, and the second gear 20 is driven to rotate, so that the door 5 is moved upward along the first slide slot 17 through the rack 18, so that the front side of the device housing 1 is opened. At this time, the plywood can be moved into the cooling chamber 2. After the pressure sensor 13 feedbacks the signal, the first bidirectional motor 19 is controlled to reverse, so that the door 5 is slowly lowered to block the front opening of the device housing 1. At this time, the roller 33 rewinds the cloth 35 on the rolling rod under the action of the winding spring 34. The plywood is abutted against the door 5 under the drive of the cloth 35.

[0058] When cooling is completed and the hatch 5 is opened, the plywood moves outward for a distance along the guide roller 36 and the drive roller 31 under the action of the cloth 35, thereby automatically extending a part of the equipment housing 1 to facilitate subsequent removal. When the plywood is completely removed, the cloth 35 is rewound on the roller 33.

[0059] In order to realize the automatic loading and unloading of plywood, please refer to Figure 1 , Figure 7 and Figure 8 , a movable frame 6 that can be raised and lowered is arranged on the equipment housing 1 in front of the hatch 5. The movable frame 6 is an I-shaped structure and is arranged horizontally on the front side of the equipment housing 1. Fixed plates 21 are vertically fixed on both sides of the equipment housing 1, and second slide rails 22 are vertically fixed on the outer side of the fixed plates 21. The rear end of the movable frame 6 is slidably arranged with the corresponding second slide rail 22. A second lead screw 23 is vertically rotated on the side of the fixed plate 21, and a second bidirectional motor 24 that drives the second lead screw 23 is fixed on the top of the fixed plate 21. The second lead screw 23 passes through the corresponding end of the movable frame 6 and is threadedly connected to the movable frame 6. Multiple groups of first position sensors 25 that are respectively adapted to the corresponding cooling chambers 2 are fixed on the side of the fixed plate 21. The second bidirectional motor 24 is controlled to work and drive the second lead screw 23 to rotate, so that the movable frame 6 moves downward on the second slide rail 22 until it moves to the position of the next first position sensor 25. After moving to the first position sensor 25 at the bottom, the second bidirectional motor 24 is controlled to reverse, so that the moving frame 6 returns to the highest position.

[0060] The movable frame 6 is provided with a displacement module 7 for movable plywood. The displacement module 7 includes a beam 71 which is horizontally slidably arranged at the front sides of both ends of the movable frame 6. The beam 71 is an L-shaped structure. The front sides of both ends of the movable frame 6 are horizontally provided with slots 72. The short side ends of the beam 71 are horizontally fixed with a plug 73 which can be inserted into the corresponding slot 72. A third bidirectional motor 74 is fixedly arranged at the end of the beam 71 on the opposite side of the plug 73. A third lead screw 88 is fixedly arranged at the output end of the third bidirectional motor 74. The third lead screw 88 is rotatably arranged with the beam 71, and the third lead screw 88 is threadedly connected with the end of the movable frame 6. A second position sensor 79 which is adapted to the beam 71 is fixedly arranged at the top of the long side of the beam 71. The third bidirectional motor 74 is controlled to work and the third lead screw 88 is driven to rotate. Thus, the beam 71 moves forward and backward through the plug 73 and the slot 72. Until the second position sensor 79 detects the position information of the hot press.

[0061] A lifting plate 75 that can be raised and lowered is slidably provided at the top of the long side end of the crossbeam 71, and a positioning plate 76 is vertically fixedly provided at the top of the end of the crossbeam 71. A fourth lead screw 77 is rotatably provided on the side of the positioning plate 76, and a fourth bidirectional motor 78 that drives the fourth lead screw 77 to rotate is fixedly provided on the top of the positioning plate 76.

A third position sensor 80 that is compatible with the lifting plate 75 is fixedly provided at the long side end of the crossbeam 71. The fourth bidirectional motor 78 is controlled to work and drive the fourth lead screw 77 to rotate. At this time, the lifting plate 75 moves downward along the crossbeam 71 until the third position sensor 80 detects the position information of the plywood.

[0062] The bottom end of the lifting plate 75 is provided with a vertical beam 81 for horizontal sliding, and the top end of the vertical beam 81 is provided with a second slide groove 82, and the bottom end of the lifting plate 75 can slide in the second slide groove 82. The top end of the vertical beam 81 is provided with a fifth lead screw 83 for horizontal rotation, and the end of the vertical beam 81 is fixedly provided with a fifth bidirectional motor 84 for driving the fifth lead screw 83. The fifth lead screw 83 passes through the bottom of the corresponding lifting plate 75 and is threadedly connected with the lifting plate 75. Before the lifting plate 75 moves, the fifth bidirectional motor 84 is controlled to start the fifth lead screw 83 to rotate, so that the vertical beam 81 moves forward to the farthest point relative to the lifting plate 75 through the second slide groove 82.

[0063] Suction cups are fixedly provided at both ends of the bottom of the vertical beam 81, and an air pump 86 is fixedly provided at the middle position of the top of the mobile frame 6.

When the position of the lifting plate 75 is fixed, the four suction cups are completely attached to the four corners of the top of the plywood. The air pump 86 is controlled to work, so as to drive the suction cups to be adsorbed on the top of the plywood through the air suction pipe 87. Then the third bidirectional motor 74, the fourth bidirectional motor 78 and the fifth bidirectional motor 84 are controlled to reverse, and the plywood is sent to the middle position of the driving roller 31.

[0064] The method for using the plywood rapid cooling device of the present invention is as follows: first, after the plywood is hot-pressed, the hot press is opened.

Before the lifting plate 75 moves, the fifth bidirectional motor 84 is controlled to start the fifth lead screw 83 to rotate, so that the vertical beam 81 moves forward to the farthest point relative to the lifting plate 75 through the second slide slot 82. When the position of the lifting plate 75 is fixed, the four suction cups are completely attached to the four corners of the top of the plywood. The vacuum pump 86 is controlled to work, so that the suction cup is driven to be adsorbed on the top of the plywood through the vacuum pipe 87. Then, the third bidirectional motor 74 , the fourth bidirectional motor 78 and the fifth bidirectional motor 84 are controlled to rotate in reverse to deliver the plywood to the middle position of the driving roller 31 .

[0066] At this time, after the plywood enters the cooling chamber 2, it first contacts the driving roller 31 and enters the cooling chamber 2 from the middle position of the driving roller 31. At the same time, the first motor 39 is driven to work, and the corresponding pulley 37 is driven to rotate through the belt 38, so that all the first gears 32 are rotated synchronously through the belt 38, and then the driving roller 31 is rotated slowly. When the plywood passes through the middle position of the driving roller 31, the driving roller 31 squeezes the plywood and drives the plywood to move. After passing through the driving roller 31, the plywood passes through the middle position of the winding roller 33. In this process, the plywood resists the cloth roll 35 and overcomes the resistance of the winding spring 34 to unfold it from the winding roller 33, so that the plywood is carried to the rear of the cooling chamber 2. After the plywood passes through the middle position of the winding roller 33 with the cloth roll 35, it passes through the middle position of the guide roller 36 and moves to the rear side. At this time, the guide roller 36 squeezes the plywood and guides the plywood until the plywood makes the cloth roll 35 contact the pressure sensor 13, and the pressure sensor 13 feeds back a signal to the outside.

[0067] After the pressure sensor 13 feedbacks the signal, the first bidirectional motor 19 is controlled to reverse, so that the hatch 5 will slowly descend to block the front opening of the equipment housing 1. During this process, the second bidirectional motor 24 drives the movable frame 6 to move downward, and according to the signal of the first position sensor 25, the plywood is repeatedly inserted into the middle position of the corresponding driving roller 31. After moving to the first position sensor 25 at the bottom, the second bidirectional motor 24 is controlled to reverse, so that the movable frame 6 returns to the highest point. At this time, all the pressure sensors 13 send signals to the outside, the first motor 39 works, and at the same time, the hatch 5 completely blocks the front side of the equipment housing 1. At this time, under the action of the winding spring 34, the roller 33 rewinds the cloth 35 on the rolling rod. Driven by the cloth 35, the plywood abuts against the hatch 5.

[0068] The air cooler 4 is controlled to work, and the refrigerated air is conveyed to the air inlet cavity 14 through the air inlet chamber 15. At this time, the gas in the air inlet cavity 14 enters the cooling chamber 2 through the air inlet groove 16. At this time, the cold air bypasses from the bottom of one end of the plywood and returns from the top of the other end of the plywood. At this time, the cold air takes away the heat of the plywood and enters the exhaust cavity 10 from the exhaust groove 12, and is discharged from the exhaust port 11. In this way, the plywood is cooled quickly, the cooling efficiency of the plywood is improved, the consistency of the cooling process is ensured, and the quality of the final product is improved. In this process, the cold air bypasses from the front end of the plywood to the top of the plywood through the vertical groove.

[0069] When cooling is completed and the hatch 5 is opened, the plywood moves outward for a distance along the guide roller 36 and the drive roller 31 under the action of the cloth 35, thereby automatically extending a part of the equipment housing 1 to facilitate subsequent removal. When the plywood is completely removed, the cloth 35 is rewound on the roller 33.
