Description

[Detailed Description of the Invention] The present invention is an extremely novel proposal for a raw material supply device for an injection molding machine. The biggest feature is that by installing one device of the present invention, it is possible to mix raw materials (i.e., so-called mixed materials with virgin raw materials and recycled materials) into an injection molding machine. It has three major functions: drying and supplying. In other words, from the viewpoint of the usage value that the three major functions mentioned above can fulfill, it is said that "fully automatic"
It can be said to be "synthetic apparatus".
Further details of the features and effects of the device of the present invention are as follows. In order to have the functions of three devices in one device,
The supply of raw materials to the injection molding machine is completely left to us.
K Can save space in the on-site factory. In other words, the compact design with a floor area of 50cm x 110cm [a whopping 0.55m ² ] makes the best use of space within the factory. Cost reduction is possible based on the use of this device. That is, the cost of molded products or molded parts can be easily reduced by the mass production effect based on the consolidation (integration) of control circuits such as the control unit of the present device. Furthermore, in relation to the above, a device that combines the three major functions of mixing, drying, and supplying raw materials to an injection molding machine based on the circuit aggregation of the electrical system has been established as a control system as a so-called raw material supply center. obtain. Furthermore, if the same raw materials are used, it is possible to supply raw materials to several injection molding machines unmanned with one device. However, each element operation such as mixing, drying, and supply is performed by equipment with excellent performance and characteristics, each formed by a unique structure that matches the physical properties of the raw material particle group.
We will never allow this kind of equipment made by other companies to follow suit. Furthermore, it is extremely easy to connect and connect other elements of the present device (for example, a mini-type runner crusher, etc.) and integrate them with the four major functions. Space, energy saving, labor saving, cost reduction,
...The practical effects of the device of this invention are immeasurable. The device of this invention has many features as listed above.
Although this is an extremely effective device, its configuration and structure will be explained below based on an example shown in the drawings. Virgin raw materials and recycled materials (this means recycled materials from pulverization such as runners) are pneumatically transported from a virgin raw material tank V and a recycled material tank R based on preset air pressures, and then air-transported by a mixing device M. Mixing [In other words, based on the theory that the mixing ratio of virgin raw materials and recycled materials is determined by the control of the air pressure that can be set in advance, the mixing ratio is highly accurate within ±1%, and furthermore, In the process of transporting the raw materials into the mixing device M , due to forced diffusion motion (i.e., the principle of gas molecular kinetic theory), the mixing ratio is exactly 100%, and phenomena such as uneven distribution and uneven distribution in the raw materials are avoided. [None at all] Raw material O is transferred to hot air circulation dryer D via storage tank C ,
Completely dry in the hot air circulation dryer D [i.e.
While a hot air chamber H is provided in the center , the air sent during the transportation of the raw material O is immediately used to radially heat the raw material O in the dryer D tank (i.e., three-dimensional heating). , after passing through the filter box F provided above, the blower B
The so-called hot air circulation dryer D is where the air is sucked in and sent to the hot air chamber N through the air pipe P again.
100% drying is possible], and the raw material O is transported by an attached pneumatic transport machine A/T [Whether it is a suction type or a pressure feed type, the molding machine and the layout of the factory etc. Depending on the relationship, either method can be applied on a case-by-case basis.
All of the above-mentioned element operations are automatically controlled based on electrical signals, and the mixing ratio of raw materials is ±1%.
Within, the mixing ratio is 100%, and on the other hand, on the dry side,
Energy saving, resource saving, 100% drying effect...the practical effects are endless. In addition, MoL in the figure indicates the injection molding machine R and C indicate the mini-type runner crusher, G indicates the pressure gauge, and the arrows along the pipeline in the figure indicate the transfer direction of the raw material O , respectively. .
