Description

Technical Field

[0001] This utility model relates to the field of cooling technology after hot pressing of OSB (Oriented Strand Board), and in particular to a cooling device for OSB after hot pressing. Background Technology

[0002] The OSB (Oriented Strand Board) hot-pressing cooling device is a piece of equipment used to cool OSB after hot pressing. It uses a cooling medium to exchange heat with the hot-pressed OSB, quickly reducing the temperature of the OSB to room temperature or a specific temperature requirement, so that it can be processed or stored later.

[0003] However, in existing technologies, some devices cool the OSB boards by placing them on shelves for natural cooling, which results in low cooling efficiency. Furthermore, vibrations from impacts are transmitted to the OSB boards, causing scratches, dents, and other defects on their surface. Especially in the initial cooling stage, when the OSB boards are still relatively soft, they are more susceptible to damage, affecting their appearance and surface flatness. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a cooling device for OSB after hot pressing. This device can absorb and buffer the impact force on the OSB after hot pressing, reduce wear on the cooling device itself and related components of the hot pressing equipment, extend the service life of the equipment, and reduce equipment maintenance costs. Compared with natural cooling or air cooling, the cooling speed is faster, which can significantly shorten the cooling time of OSB and improve production efficiency.

[0005] To achieve the above objectives, a cooling device for OSB board after hot pressing is provided, comprising a base, a plurality of telescopic rods fixedly connected to the top of the base, two first support blocks fixedly connected to the top of the base, a plurality of second fixing blocks fixedly connected to the outside of the base, a first rotating shaft rotatably connected inside the second fixing blocks, a first connecting rod rotatably connected to the outside of the first rotating shaft, a third rotating shaft rotatably connected to one end of the first connecting rod, a first fixing block rotatably connected to the outside of the third rotating shaft, a second rotating shaft rotatably connected to the inside of the first connecting rod, and a second connecting rod rotatably connected to the outside of the second rotating shaft.

[0006] According to the OSB board hot-pressing cooling device, one end of the second connecting rod is rotatably connected to a fourth rotating shaft, the outside of the fourth rotating shaft is rotatably connected to a third fixing block, and the bottom of the third fixing block is fixedly connected to a second support block.

[0007] According to the OSB board hot-pressing cooling device, the second support block is internally threaded with a threaded rod, one end of which is fixedly connected to a first bevel gear, the bottom of the first bevel gear is meshed with a second bevel gear, and the bottom of the second bevel gear is rotatably connected to the interior of the base.

[0008] According to the OSB board hot-pressing cooling device, a base is fixedly connected to the top of the telescopic rod, a third support block is fixedly connected to the top of the base, and a condenser is fixedly connected inside the base.

[0009] According to the OSB board hot-pressing cooling device, the condenser is fixedly connected to the outside of a vent pipe, and the outside of the vent pipe is fixedly connected to the inside of the base.

[0010] According to the OSB board hot-pressing cooling device, an air pump is fixedly connected to the outside of the vent pipe, and a tank cover is fixedly connected to one end of the vent pipe.

[0011] According to the OSB board hot-pressing cooling device, the inside of the can lid is fixedly connected with a plurality of first locking blocks, the outside of the first locking blocks is provided with a limiting groove, and the outside of the limiting groove is fixedly connected with a can body.

[0012] According to the OSB board hot-pressing cooling device, a rotating rod is rotatably connected inside the tank, a bearing is rotatably connected outside the rotating rod, and multiple second clamping blocks are fixedly connected outside the rotating rod. OSB boards are disposed inside the second clamping blocks, and the bottom of the rotating rod is rotatably connected to the top of the third support block.

[0013] Beneficial effects:

[0014] 1. The first connecting rod at the bottom rotates outside the third rotating shaft, thereby driving the second rotating shaft inside to rotate. The second rotating shaft drives the second connecting rod to rotate, causing the fourth rotating shaft inside the second connecting rod to rotate. This causes the third fixed block outside the fourth rotating shaft, along with the second support block at the bottom, to move, thereby driving the internal threaded rod to move. A first bevel gear is fixed at one end of the threaded rod. The first bevel gear meshes with the second bevel gear at the bottom, thereby buffering the base at the top. This can absorb and buffer a certain impact force on the hot-pressed OSB board, reduce wear on the cooling device itself and related components of the hot-pressing equipment, extend the service life of the equipment, and reduce equipment maintenance costs.

[0015] 2. Under the action of the vacuum pump, the cold air generated by the condenser enters the tank through the vent pipe, cooling the OSB sheets inside. After cooling, press the tank lid to disengage the first locking block from the limiting groove inside the tank, remove the lid, and take the OSB sheets out of the tank. This allows for rapid absorption of heat from the OSB sheets, achieving efficient cooling. Compared to natural cooling or air cooling, the cooling speed is faster, significantly shortening the cooling time of the OSB sheets and improving production efficiency.

[0025] Reference Figure 1-4 This utility model discloses a cooling device for OSB board after hot pressing, which includes a base 1. Multiple telescopic rods 2 are fixedly connected to the top of the base 1. Two first support blocks 14 are fixedly connected to the top of the base 1. Multiple second fixing blocks 6 are fixedly connected to the outside of the base 1. A first rotating shaft 7 is rotatably connected inside the second fixing block 6. A first connecting rod 8 is rotatably connected to the outside of the first rotating shaft 7. A third rotating shaft 11 is rotatably connected to one end of the first connecting rod 8. A first fixing block 4 is rotatably connected to the outside of the third rotating shaft 11. A second rotating shaft 9 is rotatably connected inside the first connecting rod 8. A second connecting rod 10 is rotatably connected to the outside of the second rotating shaft 9.

[0026] Specifically: The first connecting rod 8 rotates outside the third rotating shaft, thereby driving the internal second rotating shaft 9 to rotate. The second rotating shaft 9 drives the second connecting rod 10 to rotate, causing the internal fourth rotating shaft 13 of the second connecting rod 10 to rotate. This causes the external third fixing block 12 of the fourth rotating shaft 13, together with the bottom second support block 15, to move, thereby driving the internal threaded rod 16 to move. A first bevel gear 17 is fixed at one end of the threaded rod 16. The first bevel gear 17 meshes with the bottom second bevel gear 18, thereby buffering the top base 3.

[0027] One end of the second connecting rod 10 is rotatably connected to the fourth rotating shaft 13, the outside of the fourth rotating shaft 13 is rotatably connected to the third fixing block 12, and the bottom of the third fixing block 12 is fixedly connected to the second support block 15.

[0028] The second support block 15 has a threaded rod 16 internally connected to it. One end of the threaded rod 16 is fixedly connected to a first bevel gear 17. The bottom of the first bevel gear 17 is meshed with a second bevel gear 18. The bottom of the second bevel gear 18 is rotatably connected to the inside of the base 1.

[0029] The top of the telescopic rod 2 is fixedly connected to the base 3, the top of the base 3 is fixedly connected to the third support block 20, and the condenser 19 is fixedly connected inside the base 3.

[0030] The top of the telescopic rod 2 is fixedly connected to the base 3, the top of the base 3 is fixedly connected to the third support block 20, and the condenser 19 is fixedly connected inside the base 3.

[0031] Specifically: Under the action of the vacuum pump 21, the cold air generated by the condenser 19 enters the tank 24 through the vent pipe 5 and cools the OSB plate 27 inside the tank 24.

[0032] An air pump 21 is fixedly connected to the outside of the vent pipe 5, and a can lid 23 is fixedly connected to one end of the vent pipe 5.

[0033] The can lid 23 has multiple first locking blocks 25 fixedly connected inside, and the first locking blocks 25 have limit grooves 26 on the outside. The can body 24 is fixedly connected to the outside of the limit grooves 26.

[0034] Specifically: Pressing the can lid 23 causes the first locking block 25 inside to disengage from the limiting groove 26 inside the can body 24, thus removing the can lid 23.

[0035] The tank body 24 is rotatably connected to a rotating rod 22, and the rotating rod 22 is rotatably connected to a bearing 28. The rotating rod 22 is fixedly connected to a plurality of second locking blocks 29, and the second locking blocks 29 are provided with OSB plates 27 inside. The bottom of the rotating rod 22 is rotatably connected to the top of the third support block 20.

[0036] Working principle: When the top tank 24 encounters an impact force at the bottom of the base 3, the first connecting rod 8 at the bottom rotates outside the third rotating shaft, thereby driving the internal second rotating shaft 9 to rotate. The second rotating shaft 9 drives the second connecting rod 10 to rotate, causing the fourth rotating shaft 13 inside the second connecting rod 10 to rotate. This causes the third fixing block 12 outside the fourth rotating shaft 13, together with the second support block 15 at the bottom, to move, thereby driving the internal threaded rod 16 to move. A first bevel gear 17 is fixed at one end of the threaded rod 16. The first bevel gear 17 meshes with the second bevel gear 18 at the bottom, thereby buffering the top base 3. This absorbs and cushions the impact. The hot-pressed OSB 27 experiences a certain impact force, reducing wear on the cooling device and related components of the hot-pressing equipment, thus extending the equipment's service life. The heat generated inside the tank 24 is channeled through the condenser 19 inside the bottom base 3. Under the action of the vacuum pump 21, the cold air generated by the condenser 19 enters the tank 24 through the vent pipe 5, cooling the OSB 27 inside. After cooling, pressing the tank cover 23 disengages the first locking block 25 from the limiting groove 26 inside the tank 24, allowing the tank cover 23 to be removed and the OSB 27 to be taken out of the tank 24. This rapid absorption of heat from the OSB 27 achieves efficient cooling. Compared to natural cooling or air cooling, this method is faster, significantly shortening the cooling time of the OSB 27 and improving production efficiency.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
