[0031] The working principle of the environmentally friendly and energy-saving air energy heat pump shoe production line of the present invention is as follows: First, the design is placed at the position where the shoes need to be molded and produced through the conveyor body 1. When in use, the shoes that need to be processed are placed on the conveyor belt in the middle of the conveyor body 1 from the right side of the conveyor body 1. The shoes move from right to left on the conveyor belt, and the operator places the shoes on the workbench 2 for processing; Second, the driving motor 72 is controlled to start, and the first shift block 74 and the second shift block 75 are moved away from each other under the action of the driving motor 72, so that the first V-shaped folding door 76 and the second V-shaped folding door 77 are folded under the action of the first shift block 74 and the second shift block 75 respectively. When folding, the middle parts of the first V-shaped folding door 76 and the second V-shaped folding door 77 move outward, and the inner positions are opened when folding, and they are inclined after opening, so that one shoe can pass through at a time, and the shoe is ensured to be in the middle position. Then, the servo motor 782 and the electric motor 83 are controlled to start, and after the servo motor 782 is started, the gear is driven to The wheel column 783 drives the rack frame 785 to perform longitudinal displacement, and the first pulley 786 and the second pulley 787 drive the shift door 7811 to move leftward to a position behind the baffle 7810 through the rack frame 785, and then move left vertically longitudinally, so that the height position of the shift door 7811 is adjusted, and the height of the shift door 7811 is adjusted to a position slightly higher than the height of the shoes at the bottom side, and after the motor 83 is started, the positioning block 86 drives the baffle 87 to adjust the height position through the cooperation of the screw rod 84 and the internal thread block 85, so that the bottom position of the baffle 87 and the bottom side position of the shift door 7811 are at the same level; Third, under the action of the conveying belt in the middle of the conveying body 1, the shoes enter the first air energy box 4 through the cloth strip 7812 for drying. The cloth strip 7812 is used to block the heat and exhaust gas near the workstation, and then the shoes enter the second air energy box 5 and the third air energy box 6 for drying after being processed by the operator. The first air energy box 4, the second air energy box 5 and the third air energy box 6 are all equipped with air energy heat pumps. The hot air generated by the air energy heat pump is circulated and heated to achieve the effect of baking glue. During the heating process of the air energy heat pump, 20-30°C controllable natural wind energy is simultaneously produced and transported to the air outlet window 9 through the pipeline, so that the 20-30°C wind energy is transported to the workstation, which greatly improves the working environment of the operator; Fourth, in the process of shoemaking, drying glue will generate waste gas. An exhaust hood 12 is provided on the top side of the suction pipe 11. Three exhaust ports with silent cylindrical powerful fans installed inside are provided on the top side of the exhaust hood 12. Strong suction is carried out through the trumpet-shaped suction pipe 11, which can absorb more than 90% of the waste gas for discharge. The first air energy box 4, the second air energy box 5 and the third air energy box 6 are connected to the inside of the first air energy box 4, the second air energy box 5 and the third air energy box 6 in a plate-type manner, and photothermal synergistic catalytic oxidation functional materials are used to achieve local removal of VOCs. Fifth, after the shoes come out of the first air energy box 4, the motor 83 can be controlled to make the baffle 87 located at the bottom. At this time, the bottom of the brush rack 88 contacts the conveyor belt in the middle of the conveyor body 1, and the glue attached to the conveyor belt is scraped off during the conveyor belt transmission process to avoid the residual glue from contaminating the shoes processed later.
