[0058] Embodiment three:

[0059] This embodiment provides a method for producing a pallet based on the first and second embodiments.

[0060] The first step is to start the driving motor 26 to provide power to the reducer A25, and drive the driving shaft 22 connected thereto to rotate through the reducer A25, and cooperate with the connection of the two linkage spur gears 24 to transmit the power of the reducer A25, so that the two driving shafts 22 rotate at the same time, and transmit the power of the two driving shafts 22 to the two squeezing rollers 15 respectively by means of chains, so that the two squeezing rollers 15 rotate at the same time;

[0061] The second step is to start the motor 37, and transmit the power of the motor 37 to the cutting shaft 33 connected to the synchronous wheel A36 by means of the synchronous belt 39. Since the slitting knife belt 35 is located between the two knife belt carriers 34, when one of the cutting shafts 33 rotates, it can drive the slitting knife belt 35 to be adjusted between the two knife belt carriers 34. When the tension of the slitting knife belt 35 is insufficient, the transmission screw A31 is rotated to drive the displacement seat 32 to be displaced under the limit of the adjustment seat A30, so as to adjust the distance between the two knife belt carriers 34 and tighten the slitting knife belt 35. When the slitting knife belt 35 is used, the grinding motor 44 can be started to drive the feeding frame 46 to rotate continuously, so as to prompt the grinding disc 45 to grind the slitting knife belt 35 to ensure the cutting smoothness of the slitting knife belt 35. At the same time, the transmission screw B42 can be rotated to drive the guide seat 43 to be displaced under the limit of the adjustment seat B41, thereby adjusting the contact degree between the grinding disc 45 and the slitting knife belt 35.

[0062] The third step is to start the feeding motor 50 and cooperate with the reducer B49 to provide power to the active conveying roller 47, so that the conveyor belt is transmitted between the active conveying roller 47 and the driven conveying roller 48, and then the pallet material is placed on the conveyor belt to be conveyed to the squeezing roller 15 through the conveyor belt. When the pallet material passes through the squeezing roller 15, the pallet material will be squeezed by the squeezing roller 15, so that the placement groove 3 is generated on the pallet material, and after the pallet material passes through the squeezing roller 15, the pallet material will contact the slitting knife belt 35. Under the continuous operation of the slitting knife belt 35, the pallet material can be cut from the middle to generate two upper and lower pallets;

[0063] When the thickness of the pallet changes, the transmission motor 19 is first started to drive the adjustment seat A30 to turn the matching worm gear 18, thereby driving the central shaft 17 to rotate, providing power to the corresponding worm elevator 13, and then using the worm elevator 13 to adjust the distance between the two squeezing rollers 15 to meet the processing needs of pallet materials of different thicknesses;

[0064] When the distance between the two squeezing rollers 15 changes, it is necessary to start the hydraulic cylinder 55 to push the stabilizing frame 53, and cooperate with the connection between the stabilizing frame 53 and the feeding frame 46, so that the feeding frame 46 can be adjusted in height under the auxiliary support of the support arm 51 and the contact wheel A52, so that the height of the conveyor belt corresponds to the squeezing roller 15;
