Description
Technical Field
[0001] The utility model relates to the field of hot pressing devices, in particular to a hot pressing device for wood fiberboards. Background Art
[0002] The wood fiberboard hot press is a hot press used to produce wood fiberboard. Wood fiberboard, also known as medium-density fiberboard, is a board made of wood fiber and adhesive through high temperature and high pressure. It has uniform density and excellent flatness. The hot press can solidify the wood fiber and adhesive in the mold through heating and high pressure to form a solid board structure. This curing process ensures the stability and durability of the wood fiberboard.
[0003] When a hot pressing device produces wood fiberboard, the wood fiberboard raw materials are placed between the hot pressing plates, and the hydraulic push rod is started to close the hot pressing plates together, so that the hot pressing plates can tightly compress the wood fibers together through high temperature and high pressure, thereby increasing the density of the wood fiberboard. When the hot pressing device takes out the finished wood fiberboard, the hands and body will be close to the hot pressing plates of the hot pressing device. Since the hot pressing plates will be heated during the hot pressing process, there will still be a certain amount of heat in the hot pressing plates when the wood fiberboard is taken out, which makes it easy for the hands or body of the staff to be burned. Therefore, we propose a hot pressing device for wood fiberboard. Utility Model Content

[0027] See also Figure 1-Figure 4 and Figure 6The utility model provides a technical solution: a wood fiberboard hot pressing device, comprising a hot press 1 and a hot pressing plate 101, wherein the hot press 1 is sequentially installed with the hot pressing plate 101 and the hydraulic push rod 102, wherein a non-brake motor 2 is installed inside the hot press 1, and the output shafts at both ends of the non-brake motor 2 are respectively fixed to the first bevel gear 201 through a center rod, and the first bevel gear 201 is connected to the second bevel gear 202, and the first bevel gear 201 and the second bevel gear 202 are respectively movably connected to the hot press 1 through bearings, a connecting rod 203 is fixed to the lower side of the second bevel gear 202, and a guide wheel 204 is fixed to the outer side of the connecting rod 203, and the connecting rod 203 and the guide wheel 204 are respectively connected to the hot press 1 through a center rod. The bearing is movably connected to the hot press machine 1, and the hot press machine 1 is provided with a receiving groove 205 on the outer side of the guide wheel 204, a connecting pad 2051 is bonded to the side of the receiving groove 205 close to the hot pressing plate 101, a connecting spring 206 is provided in the groove of the guide wheel 204, and a connecting frame 207 is fixed to one side of the guide wheel 204, and a fixing pad 208 is bonded to one end of the connecting frame 207, a magnetic block 209 is inlaid on one side of the connecting frame 207, an electromagnet 210 is installed on the side of the receiving groove 205 close to the magnetic block 209, the first bevel gear 201 is meshed with the second bevel gear 202, the connecting pad 2051 and the fixing pad 208 are made of rubber, and the magnetic block 209 and the electromagnet 210 are magnetically attracted.
[0028] In specific implementation, according to Figure 1-Figure 4 and Figure 6 When the hot pressing device produces wood fiberboard, the wood fiberboard raw material is placed between the hot pressing plates 101, and the hydraulic push rod 102 is started to close the hot pressing plates 101 together, so that the hot pressing plates 101 can tightly compress the wood fibers together through high temperature and high pressure, thereby increasing the density of the wood fiberboard. When the hot pressing plates 101 of the hot pressing device are fully unfolded, when the finished wood fiberboard needs to be taken out, the electromagnet 210 is powered off, so that the electromagnet 210 and the magnetic block 209 are separated from the magnetic attraction. At this time, the connecting spring 206 is contracted, so that one end of the connecting spring 206 pulls the connecting spring 206 to move the connecting spring 206. The connecting frame 207 does not automatically lock the rotor when the non-braking motor 2 stops running, so that the output shaft of the non-braking motor 2 will not be restricted from rotating, so that the connecting frame 207 can rotate, and the connecting frame 207 can rotate to hit the wood fiberboard. Then, the connecting pad 2051 and the fixed pad 208 are made of rubber material with a certain deformation ability, so that the connecting pad 2051 can reduce the sound of the connecting frame 207 hitting, and the fixed pad 208 can prevent the connecting frame 207 from damaging the wood fiberboard. At this time, the wood fiberboard is partially moved out of the hot pressing plate 101 under the impact of the connecting frame 207;
[0029] At this time, the non-brake motor 2 can be started, so that the output shafts at both ends of the non-brake motor 2 drive the first bevel gear 201 to rotate, and the first bevel gear 201 is meshed with the second bevel gear 202, so that the first bevel gear 201 drives the second bevel gear 202 to rotate, and the two second bevel gears 202 rotate in the opposite direction. At this time, the second bevel gear 202 drives the connecting rod 203 to rotate respectively, so that the connecting rod 203 retracts the connecting frame 207 to its original position through the guide wheel 204, so that the magnetic block 209 and the electromagnet 210 are attached together, and then the electromagnet 210 is energized to make the magnetic block 209 and the electromagnet 210 magnetically attracted and restricted together, so that the connecting frame 207 is restricted inside the storage slot 205 and is not easy to rotate, so that the connecting frame 207 can hit the wood fiberboard again, so that when the staff takes out the wood fiberboard, their hands and bodies do not need to be close to the hot pressing plate 101 of the hot pressing device, and are not easily burned.

[0032] In specific implementation, according to Figure 3 , Figure 4 and Figure 6When the connection spring 206 of the hot pressing device needs to be replaced, the electromagnet 210 is powered off to shrink the connection spring 206, and then the limit bolt 2061 is rotated to be threadedly connected with the connection frame 207 through the limit bolt 2061, so that the limit bolt 2061 is separated from the connection frame 207, and then the electric telescopic rod 304 is started to separate the movable end of the electric telescopic rod 304 from the limit groove 303, so that the whole staff can pull the docking block 302 to separate the docking block 302 from the docking groove 301. At this time, the staff can remove the old connection spring 206 and connect the docking block 302 of the new connection spring 206 with the docking groove 301. The docking is performed by matching the cross-sectional size of the docking groove 301 with the cross-sectional size of the docking block 302, so that the docking block 302 is not easy to shake inside the docking groove 301.

When taking out the finished wood fiberboard, the electromagnet 210 is powered off, and the connecting spring 206 is contracted at this time, so that the connecting frame 207 can rotate to hit the wood fiberboard. At this time, the wood fiberboard is partially moved out of the hot pressing plate 101 under the impact of the connecting frame 207, so that when the staff takes out the wood fiberboard, the hands and body do not need to be close to the hot pressing plate 101 of the hot pressing device, and are not easily scalded.
