EMBODIMENT

[0024] Figures 1-4This invention illustrates an auxiliary feeding device for a refrigerator door liner vacuum forming machine according to an embodiment of the present invention. The device includes: a conveying device 1; a support frame 2 is provided on the surface of the conveying device 1; a support fixing plate 3 is bolted to the top of the inner cavity of the support frame 2; a cylinder 4 is bolted to the top of the inner cavity of the support frame 2; the output end of the cylinder 4 extends through to the bottom of the support fixing plate 3 and is bolted to a support connecting plate 5; a round rod 6 is welded to the bottom of the support connecting plate 5; a pushing structure 7 is provided at the bottom end of the round rod 6; and multiple long round rods 8 are welded to the bottom of the support connecting plate 5. A rubber pad head 9 is fixedly connected, and four guide limit rods 10 are welded to the top of the support connecting plate 5. By the position of the guide limit rods 10, the cylinder 4 can push the support connecting plate 5 to slide, so that the direction of the slide of the support connecting plate 5 is vertically guided and limited, so that the support connecting plate 5 can be kept to slide vertically and avoid the support connecting plate 5 from tilting. The surface of the support fixing plate 3 has four circular grooves, and the surface of the guide limit rods 10 is slidably connected to the inner cavity of the circular grooves. The surface of the conveying device 1 is equipped with a vacuum forming machine 11, which is located in front of the support frame 2.

[0025] Working Principle: When using this invention, the user activates the cylinder 4 to push the support connecting plate 5 downwards. This causes the support connecting plate 5 to simultaneously slide the round rod 6, the pushing structure 7, the long round rod 8, and the rubber pad 9 downwards. Subsequently, the bottom end of the rubber pad 9 pushes against the thermoplastic-molded refrigerator door liner, allowing the refrigerator door liner to detach from the plastic body that provided support during thermoplastic molding. Simultaneously, when the rubber pad 9 contacts the refrigerator door liner, the inclined material feed head 75 also abuts against the connection between the refrigerator door liner and the plastic body. If the refrigerator door liner and the plastic body remain connected during the downward movement of the rubber pad 9, the inclined material feed head 75 will remain in place, compressing the spring 74. Under the rebound force of the spring 74, the downward pushing force of the inclined material feed head 75 is increased, thus pushing the inclined material feed head 75 to detach the refrigerator door liner from the connection between it and the plastic body. This allows the molded refrigerator door liner to detach from the inner cavity of the main plastic more quickly, accelerating the demolding process of the refrigerator door liner.

[0026] In summary, the auxiliary feeding device of this refrigerator door liner vacuum forming machine compresses the spring 74, thereby increasing the pushing force of the inclined feeding head 75 under the action of the spring 74. This causes the inclined feeding head 75 to push the connection between the refrigerator door liner and the plastic body, thus enabling the shaped refrigerator door liner to detach from the inner cavity of the main plastic more quickly, thereby accelerating the demolding process of the refrigerator door liner.
