[0073] like Figure 3-4As shown, the third driving device 17 is installed on the mounting frame 181, and the output end of the third driving device 17 is connected to the third air intake hood 14; the top surface of the third air intake hood 14 is provided with a first valve 141, and the interior of the third air intake hood 14 is provided with two air intake cavities 142, and the two air intake cavities 142 can be connected to each other through the first valve 141, and the first sealing rubber gaskets (not shown in the figure) are installed around the bottom surfaces of the two air intake cavities 142; the first driving device 15 includes a rack 151, a first gear 152 and a first motor 153, the rack 151 is installed on the first frame 11, the first motor 153 is installed on the movable plate 12, and the output end of the first motor 153 is installed with the first gear 152, and the first gear 152 is engaged with the rack 151. In this embodiment, the third drive device 17 is a cylinder, and the first valve 141 is connected to an external air supply device. During demolding, the external air supply device introduces air into the first valve 141, and the air then enters the interior of the drying mold through the air inlet chamber 142. It should be noted that for double-sided slurry absorption drying products, only a single air inlet chamber 142 is required, that is, there is no need to open the first valve 141, so that the two air inlet chambers 142 are independent of each other. However, for single-sided slurry absorption drying products, two air inlet chambers 142 are required for air intake, that is, the first valve 141 needs to be opened to connect the two air inlet chambers 142. Elastic first sealing gaskets are installed around the bottom surfaces of the two air inlet chambers 142 to prevent leakage during blowing. In this embodiment, during operation, the first motor 153 drives the first gear 152 to rotate, and the first gear 152 moves left and right on the rack 151, thereby moving the movable plate 12 left and right, which is convenient and fast, and has high transmission efficiency.

For single-sided slurry absorption products, since the product has no inner cavity, the hot air directly passes through the product from the air inlet of the upper mold and the mold air holes to the mold air holes of the lower mold, and is discharged from multiple air inlets of the lower mold. Furthermore, because the upper mold and the lower mold are provided with separate left and right air inlets, and cooperate with the control valves, the flow direction of the hot air can be controlled, thereby realizing the drying of single-sided slurry absorption and double-sided slurry absorption products. In this embodiment, the second frame 21 is provided with two conveying rails 4, each conveying rail 4 is installed with the moving trolley 5, and the moving directions of the two moving trolleys 5 are opposite.

The two first air intake hoods 241 are both controlled by the same first heat distribution pipe 61 and the same second hot air pipe 262 to control the air intake, and the two second air intake hoods 242 are both controlled by the same third hot air pipe 263 and the same fourth heat distribution pipe 64 to control the air intake, which is convenient and fast.In this embodiment, the first hot air pipe 261, the second heat branch pipe 62, the third hot air pipe 263 and the fourth heat branch pipe 64 are all wrapped with a heat insulation layer, thereby reducing the loss of heat energy and ensuring that heat energy can be directly provided to the drying products, thereby achieving the effect of improving heat energy utilization.

When demoulding and taking materials, the air intake component 35 is moved into the moving trolley 5 Inflation separates the product from the mold, thereby achieving the effect of assisting demoulding. After demoulding is completed, the first driving device 7 drives the movable seat 32 to move to the right, so that the movable seat 32 moves to the loading station at the right end of the third frame 31, and the product is placed on the mold of the movable trolley 5. Then the air intake component 35 inhales air, and the product is tightly fitted on the mold of the movable trolley 5 through vacuum adsorption, and then a new round of drying is started; this application uses the sixth driving device 37 and the movable seat 32 to link the loading station and the taking station to achieve reciprocating continuous operation, thereby achieving the effect of improving the production efficiency of the turning machine; further, through the pulling component 33 and the seventh driving device 38, it is ensured that there is enough space for taking and loading materials after the movable trolley 5 moves into place, thereby ensuring the stability of the work, and through the air intake component 35, the movable trolley 5 is assisted in demoulding and loading the mold, thereby further improving production efficiency.

In this embodiment, the sixth driving part 371 and the seventh driving part 381 are both motors. When working, the sixth driving part 371 drives the second gear 373 to rotate, so that the rack 372 drives the movable seat 32 to move left and right, and the seventh driving part 381 drives the chain 384 to rotate. The rotation of the chain 384 drives the pulling component 33 to slide on the fourth slide rail 362, which is convenient and fast, and has high transmission efficiency.
