The utility model relates to a feeding system, in particular to a central conveying pipe with a three-pronged mouth.
The feeding system of the existing injection molding machine uses the electric control system to control the feeding fan to pump the material to ensure continuous and uninterrupted operation. During the feeding process, the three-way pipe on the connected vacuum pipeline will follow the feeding amount for a long time. The accumulation of sulphur leads to blockage of the pipeline, which makes the machine run inefficiently.

Detailed ways

In order to enable the examiner to further understand the structure, features and other purposes of the present utility model, the attached preferred embodiments are now attached with drawings for detailed description as follows. The embodiments illustrated in the drawings are only used to illustrate the utility model. The technical solution does not limit the utility model.

As shown in Figure 1, Figure 1 is a schematic diagram of the central conveying structure of the utility model with a three-pronged pipe. The central conveying includes an injection molding unit 1, a storage hopper provided on the right side of the injection molding unit 1, a dust collector 3, and a fan 4. The control system 5 and the common pipe conveying system 6 arranged between the injection molding unit 1 and the storage hopper 2, and between the injection molding unit 1 and the dust collector 3 and the fan 4; among them, the common pipe conveying system 6 includes several cutoff valves 61 and several Three-pronged pipe 62; wherein, the top nozzle of each injection molding machine in the injection molding unit 1 is connected to the bottom opening of each cutoff valve 61 through the air supply pipe, and the cutoff valve 61 is arranged in each correspondingly The upper part of the injection molding machine is connected to the dust removal machine 3 on the right side of the injection molding unit 1 through the air supply duct horizontally connected to each cutoff valve 61, and the right side of the dust removal machine 3 is connected to the fan 4, and the dust collector A storage hopper 2 is provided on the left side, and the storage hopper 2 is connected with a conveying pipe.

At the left nozzle of the leftmost injection molding machine in the injection molding unit 1, the left nozzles of the remaining injection molding machines in the injection molding unit 1 are respectively connected to the diagonally upward branch nozzles of the trigeminal pipe 62 through a branch pipe. Preferably, The injection molding unit 1 is a number of injection molding machines placed in N groups in parallel, and the number of injection molding machines in each group of the several injection molding machines in the N groups is greater than or equal to 4, and the injection molding unit can be set to N+4, a total of 20-30 units In the injection molding machine, in the N groups of several injection molding machines placed in parallel, a three-pronged pipe 62 is provided above each two injection molding machines, and a cut-off valve is provided at the bottom of the storage hopper 2. The cut-off valve and the air cut-off valve The valve 61, the distributing valve 62, and the anti-purge valve 63 are controlled by photoelectric switches.
