A vacuum tube 209 is connected between the two adsorption connection boxes 208. A fixed air pump 210 is installed at the position of the vacuum tube 209 at the top of the sliding closed sleeve 204 corresponding to the position of the vacuum tube 209 through the motor seat. The fixed air pump 210 and the vacuum tube 209 are clamped and connected through an adapter to achieve steady air inlet and outlet processing. A circulation pipe 211 is connected between the two sliding closed sleeves 204. A circulation fan 212 is embedded in the inner side of the circulation pipe 211 and is clamped.

[0028] For stable operation of the equipment, the input ends of the electric heating fixing plate 202, the lifting electric push rod 203, the pressing electric push rod 205, the positioning electric push rod 207, the fixed air pump 210 and the circulating fan 212 are all electrically connected to the output end of the external power supply.

[0029] The side end of the fixed support frame 1 is provided with an inlet and outlet assembly 3, which includes a rotating motor 301, a processing fixed frame 302, a switching electric slide rail 303, a switching processing frame 304, a locking electric push rod 305, a picking suction cup 306, a fixed suction pipe 307 and a processing air pump 308;

[0030] The top of the switch frame 304 is fixed with a switching electric slide 303, and the top of the switching electric slide 303 is installed with a switching processing frame 304. The switching processing frame 304 slides and fits with the processing fixed frame 302 to achieve steady sliding alignment processing.

[0032] The working principle and use process of the present invention are as follows: when producing office chair backrests, the staff uses external feeding equipment to place the material on the side end of the fixed support frame 1, and the electric heating fixed plate 202 preheats the bottom mold 201. The rotating motor 301 drives the processing fixed frame 302 to rotate along the fixed support frame 1, and the switching electric slide rail 303 drives the switching processing frame 304 to slide along the processing fixed frame 302, and moves the picking suction cup 306 to the top of the material. The engaging electric push rod 305 drives the picking suction cup 306 to move downward, and the picking suction cup 306 is moved to the top of the material. 6 is attached to the top of the material, and the air between the picking suction cup 306 and the material is extracted by the processing air pump 308 and the fixed suction pipe 307, and the vacuum extraction is used to achieve steady picking. After the picking is completed, the engaging electric push rod 305, the switching electric slide rail 303 and the rotating motor 301 drive the material to move to the top of the bottom mold 201, achieving steady feeding and alignment processing, and through rotation adjustment and telescopic adjustment, the accuracy of feeding alignment is guaranteed, so that during the feeding process, it can effectively avoid large position deviation, which leads to abnormal appearance of the product;

[0033] When the raw material is placed at the top position of the bottom mold 201, the pressing electric push rod 205 drives the top mold 206 to move down along the sliding closed sleeve 204, and the positioning electric push rod 207 drives the adsorption connection box 208 to move down, and the adsorption connection box 208 is attached to the top of the material. The material is adsorbed and fixed through the vacuum tube 209, the fixed air pump 210 and the adsorption connection box 208. After adsorption and fixation, the pressing electric push rod 205 drives the top mold 206 to rise, and the positioning electric push rod 207 drives the adsorption connection box 208 to rise, and the material is attached to the bottom end of the top mold 206. The lifting electric push rod 203 drives the sliding closed sleeve 204 to move downward, and the sliding closed sleeve 204 is attached to the bottom end of the top mold 206. The sliding closing sleeve 204 is fitted and aligned with the bottom mold 201. At this time, under the closed environment and the heating effect of the electric heating fixing plate 202, the material softens, and the pressing electric push rod 205 drives the top mold 206 and the material to move down and fit against the inner side of the bottom mold 201. Continuous pressurization is used to realize the molding of the chair back. During the molding process, the circulation pipe 211, the circulation fan 212 and the inlet and outlet pipe 213 drive the hot air at the position of one of the bottom molds 201 and the sliding closing sleeve 204 to circulate to the other bottom mold 201 and the inner side of the sliding closing sleeve 204, realizing heat exchange processing, accelerating the cooling of the product molding, and recovering the heat to reduce resource waste.
