[0002] Pallets are the medium that transforms static goods into dynamic goods. They are a cargo platform, and they are also movable platforms, or movable ground. Even goods that lose their flexibility when placed on the ground will immediately become mobile and flexible once they are loaded on pallets, because the goods loaded on pallets are ready to move at any time. This dynamic loading and unloading method using pallets as the basic tool is called pallet operation.

[0003] With the development of the logistics industry, the utilization rate of pallets in various industries has greatly increased. However, the pallets on the market are prone to damage during actual use, especially the legs of the pallets. Since the fork entrance of the pallet is the entrance and exit for the forklift to pick up goods, when the forklift lifts heavy goods and the fork does not fall to the ground, the forklift will instantly pull out the fork, which will cause the panel of the pallet entrance to be broken and difficult to repair. The damage of the legs cannot increase the turnover rate of the pallet. The combined pallet can replace the damaged legs, but for the molded or injection-molded pallets, once the legs are severely damaged, the pallet will be directly scrapped. On this basis, in order to strengthen the strength of the pallet legs, the PP prepreg tape heating infiltration process is usually used to wrap the legs to make them stronger, which can reduce the damage of the entire pallet. rate, but the problem that follows is: the application process of existing prepreg tapes is mostly carried out by manual fire baking. On the one hand, affected by the manual processing method, the work progress is slow, the labor intensity of workers is relatively high, and there is a certain degree of danger, which cannot well protect people's personal safety. On the other hand, the firmness of fire baking is limited, affecting the functionality of use. For this reason, we provide a method that effectively enhances the strength of the surface of the pallet leg, makes it impact-resistant and tough, and fully improves the strength of use.

The bracket 11 located above the pallet body 1 is sequentially arranged from top to bottom with a driving mechanism, a heating mold and a heating unit. The driving mechanism is arranged in two groups in parallel front and back, and corresponds to the legs 1b of the pallet body 1 and the fork of the pallet frame 1a, respectively. That is to say, the driving mechanism located in the front is used to drive the heating mold to fit with the legs 1b of the pallet body 1 to support the support. The leg prepreg tape 10 is heated, and the driving mechanism located at the rear is used to drive the heating mold to fit with the fork entrance of the tray body 1 to heat the tray prepreg tape 9. In this way, it can ensure that the leg prepreg tape 10 and the tray prepreg tape 9 are respectively applied to the corresponding positions of the tray body 1, thereby improving the bonding effect and meeting the use requirements. Furthermore, the driving mechanism includes a mounting plate 2 connected to the upper part of the bracket 11, which supports the installation of the cylinder 3 and ensures its stability. The mounting plate 2 is provided with a cylinder 3 for providing downward pressure to ensure the effective implementation of the application process. The output end of the cylinder 3 is provided with a fixing plate 4, which provides convenient conditions for the connection between the cylinder 3 and the heating mold to ensure the use requirements.
