Description of the new disk. [Technical field of the new type] • This creation is about the hopper stop structure of a plastic molding machine, especially a plastic molding machine material that can effectively prevent raw materials from being attracted to the feeding tube. ^ Retaining structure. [Prior art] As shown in FIG. 4 and FIG. 5, it is a conventional hopper 7 combined with a plastic molding machine, which includes a feeding bucket 7 1 for containing raw materials, and a silver bucket 7 1 has a storage inside. The space 7 1 1 has a suction opening 7 1 2 at the top edge thereof, and a feeding pipe 7 丄 3 at the side edge, a discharge opening 7 1 4 at the bottom, and a bottom edge of the feeding barrel 7 i A transparent cylinder 8 is installed, which is originally input by the feeding pipe 713 and output to the injection plastic 2 machine through the transparent cylinder 8; the bottom of the feeding barrel 7 1 is provided with a valve group 9 and the door 2 = Including-the 9th bar of the transparent barrel 8 and the 9th bar of the crossbar = the moving rod 9 2 'The moving rod 9 2 extends to the two ends respectively _ support = φ 21 and-by the abutment member 922 A lever 911 is provided on one side of the lever 91 away from the supporting arm 921. The supporting arm 921 is provided with a door piece 923 for closing the discharge opening. The transparent barrel 8 cooperates with the abutting member 92 2 and a For controlling the switch M of the suction device. Tian Raw Material Lost Day ^ " Because the raw materials are stacked on the valve plate 9 2 3 and press the support arm 9 2 1 direction: pivot, lean against the piece 9 2 2 and push up against the switch 8 1 to control the suction device to stop the air exhaust 'and If the raw material is consumed by the injection molding machine, the actuating rod 9 2 is pressed by the counterweight 9 workers, and the abutting piece 9 2 2 leaves the switch 8 i, and opens _ i and ㈣ M279484 sucks The wind device draws air, so that the raw materials continue to be input through the feeding pipe 7 1 3. In fact, the factory building usually uses one suction device to configure at least two injection molding machine hoppers, and the raw material inlets are connected to the same raw material storage and tank. Therefore, when the suction device is performing ventilation, it is at the suction port 7 Position 1 2 caused a low pressure relative to the feeding tube 7 1 3, so when one of the injection molding hoppers stopped drawing air, the negative pressure of the other suction devices on the raw material storage tank caused the feeding tube 7 1 3 relative to the output The low pressure of the material inlet 7 1 4 causes a situation in which the raw materials ready to be sent out of the forming machine are pumped back to the raw material inlet 7 B 1, thereby causing waste in manufacturing costs and production time. [New content] The main purpose of this creation is to solve the above problems and provide a hopper blocking structure of a plastic molding machine, and the feeding barrel has a receiving space, and the receiving space of the feeding cylinder is connected to each other. The feeding pipe, and an exhaust pipe, the exhaust pipe are in communication with the exhaust device. The bottom of the feeding barrel is formed with an opening of 4 openings, and a first valve for closing the opening is installed in the feeding barrel. , The side edge of the feeding barrel is provided with a second valve group for closing the feeding pipe; accordingly, when multiple groups of feeding cylinders are engaged in the feeding operation, if one of the feeding cylinders is temporarily suspended, the other groups The low pressure formed by the feeding tube to the feeding tube of the feeding tube can be blocked by the second group of raft door groups and prevented from being sucked into the feeding tube by the raw material, thereby further ensuring the vacuum of the suction motor and reducing the horsepower. ^ To save energy, reduce unnecessary waste of raw materials and reduce production costs. In order to achieve the aforementioned purpose, the creative system includes: a feeding barrel, the feeding barrel has a storage space, and the feeding barrel is connected to a feeding pipe, and an exhaust pipe, the exhaust pipe and the exhaust air The device phase 6 is connected with M279484. The feeding tube has a nozzle opening in the accommodation space, and the bottom of the feeding barrel forms an open opening; a first valve group is installed at the bottom of the feeding barrel. And can be used to open and close the air flow path of the opening; ^ A hopper is 'located below the silver bucket' and the hopper is in communication with the opening of the forging bucket and can be used for storing raw materials. A switch for opening and closing the air extraction device; the feeding barrel is provided with a second valve group, and the second valve group can be used to open and close the air flow path of the feeding pipe. The above and other objects and advantages of this creation can be easily understood from the detailed description and accompanying drawings of the selected embodiments below. Of course, this creation may be different in some other parts or arrangements of other parts, but the selected embodiment is explained in detail in this specification and its structure is shown in the drawings. [Embodiment] Please refer to FIG. 1 to FIG. 3, which are the structure of the embodiment selected for the creation.
