[0024] The pushing mechanism is arranged at one side of the feed port of the hot pressing equipment, and comprises a supporting frame 4, and legs are arranged under the supporting frame 4 for supporting and raising the whole equipment.

[0025] An unpowered roller conveying mechanism is symmetrically fixed on both sides of the support frame 4, and the roller conveying mechanism includes two parallel frames 5. The cross-section of the frame 5 is L-shaped. Based on this shape, the horizontal part of the bottom of the frame 5 can be welded to the support frame 4, or fixed to the support frame 4 by screws, while the upright part facilitates the installation of the roller assembly.

[0026] The top side of the frame 5 is provided with assembly grooves 6 at equal intervals along its length direction. The assembly grooves 6 are rectangular grooves and can be limited in circumferential direction. A plurality of roller parts 7 are provided at equal intervals between two frames 5 in the same group. A roller shaft that rotates with the roller part 7 is centered through the roller part 7. Square plug-in blocks 8 are fixed at both ends of the roller shaft. The plug-in blocks 8 correspond to the assembly grooves 6. Simply inserting the plug-in blocks 8 into the assembly grooves 6 can realize simple assembly of the rollers. The above roller mechanism has a simple structure, is practical, has low cost, is easy to maintain and adjust the size and spacing of the rollers, and is strong and durable.

[0027] A driving shaft 9 is rotatably mounted in the center of one side frame of the support frame 4, and a driven shaft 10 is rotatably mounted on the other side frame. The driving shaft 9 and the driven shaft 10 are both arranged between two sets of roller conveying mechanisms.

[0033] The method of using the device is to stack the sheets on the pallet 1, and then place the pallet 1 on the roller conveyor mechanisms on both sides through hoisting cooperation, at this time, let the pushing accessories 17 be located in the following manner: Figure 1 The end shown (the end away from the hot pressing device) is positioned, and the hook block 22 is inserted into the matching hole 3. The transmission chain 16 is started to rotate in the direction of the hot pressing mechanism, and the pushing accessory 17 can push the support plate 1 to move on the roller wheel 7, thereby realizing the feeding of the hot pressing device.
