The invention also provides a further preferred embodiment, on the basis of the above embodiment, a pressure sensor is arranged at the side part of at least one U-shaped supporting plate 7 fixedly provided with a first sponge cushion 8 for detecting the weight of the wooden door and the pressure exerted by the inflatable cushion 1, the pressure exerted by the inflatable cushion 10 on the wooden door is designed to be in direct proportion to the weight of the wooden door so as to realize effective pressing and fixing of the wooden doors with different weights, and allowance design is made for one end of a screw rod 14 far away from a vertical plate 6, a groove for allowance is arranged at the top and the bottom in a protecting box 3 at one side far away from the vertical plate 6, a plate for allowance is connected in the groove for allowance in a sliding way, an electromagnet is arranged on the inner wall of one side of the groove for allowance perpendicular to the sliding direction, one end of the plate for allowance is fixedly connected with a magnet, one end of the inner wall of one side of the groove for allowance and one end of the plate for allowance are connected with the same spring, the set weight typical value P of the wooden door weight of the starting allowance design is set by the controller 36_{Is provided with}After loading a plurality of wooden doors into two corresponding U-shaped supporting plates 7, the weight of the wooden doors is detected by the pressure sensor, and an initial pressure value P is obtained₀The weight of the wooden door is transmitted to the controller 36 through the data transmission module, and the data processing and calculating module in the controller 36 judges whether the weight exceeds the set weight general value P or not according to the weight of the wooden door_{Is provided with}And calculating an applied pressure value P₁When P is₀≤P_{Is provided with}During the loading operation, the controller 36 closes the electromagnetic valve 38 to seal the air release pipe 37, controls the motor 20 to reversely rotate and control, so that the placing box 5 gradually enters the protective box 3, detects the pressure value P through the pressure sensor during the process, and judges that the current pressure value P isWhether the weight of the wood door is larger than the weight of the wood door and the applied pressure value P₁Sum, when P > P₀+P₁When the pressure value P is reached, the electromagnetic valve 38 is controlled to be opened for air release, and the current pressure value P falls back to the weight of the wood door and the applied pressure value P₁When the pressure is over-loaded, the electromagnetic valve 38 is closed to ensure that the inflatable cushion 10 is not inflated completely and continuously, so that the U-shaped supporting plate 7 is prevented from being fatigue-damaged due to pressure overload; when P is₀＞P_{Is provided with}When the allowance design is started, the electromagnet is controlled to be electrified to have magnetism, the magnet at one end of the allowance plate is attracted, the allowance plate slides into the allowance groove, the adjusting range of the screw rod 14 is expanded, the pressure value given to the wooden door by the inflatable cushion 10 is further improved, the application range of the device to the weight of the wooden door is further expanded, and when the pressure value is P, the electromagnet has magnetism, the magnet at one end of the allowance plate slides into the allowance groove, the application range of the device to the weight of the wooden door is further expanded₀≤P_{Is provided with}When the wooden door is in a common weight, the allowance design is not started, so that the wooden door only uses the common length of the screw rod 14, the movable plate 15 does not need to slide on the screw rod 14 for the whole length, and the efficiency of common loading and transportation is improved. The working principle is as follows: by pushing the whole device to a proper position, opening the electromagnetic valve 38, starting the motor 20 to rotate forward, so that the two screw rods 14 synchronously rotate in the same direction, the movable plate 15 drives the placing box 5 and the vertical plate 6 to gradually slide out of the protective box 3, the vertical plate 6 drives the plurality of second self-locking universal wheels 39 to roll, the rotating shaft 24 drives the cam 27 to rotate under the transmission action of the second belt pulley 21, the third belt pulley 25 and the second belt 26 during the rotation of the two screw rods 14, the cam 27 is driven to rotate under the continuous rotation action of the cam 27 and the elastic action generated by the spring 31 is matched, so that the piston 28 reciprocates up and down in the air pumping cylinder 23, outside air is sucked into the air pumping cylinder 23 through the air suction pipe 32 and then discharged into the air cavity 11, and the air entering the air cavity 11 is discharged from the air discharge pipe 37 due to the open state of the electromagnetic valve 38, so that the plurality of inflatable cushions 10 cannot be inflated temporarily, when the movable plate 15 moves to the end of the screw rod 14, the motor 20 stops working, the placing box 5 moves out of the protective box 3 at the moment, the two sides of the wooden door are respectively and horizontally inserted into the two U-shaped supporting plates 7 on the same horizontal plane, the electromagnetic valve 38 is closed to seal the air release pipe 37, the motor 20 is started to rotate reversely, the movable plate 15 drives the placing box 55 to gradually enter the protective box 3, the placing box 5 drives the vertical plate 6 to gradually approach to the anti-blocking plateThe direction of protective housing 3 removes, and after air bleed 37 sealed, the air in air cavity 11 was discharged corresponding inflatable packer 10 from a plurality of intake pipes 12 respectively and was compressed tightly the timber in fixed, when accomodating placing box 5 in protective housing 3 completely, can stop motor 20 work.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
