Description

Detailed Description of the Invention "Field of Industrial Application" The present invention is used in the field of manufacturing synthetic resins, oils and fats, foods, pharmaceuticals, etc. to process fluid substances that have the property of solidifying under certain conditions into granular or linear forms. This invention relates to a molding device for solidifying into a shape.

"Prior Art" Conventionally, as one type of molding apparatus, a molding apparatus configured as shown in FIGS. 3 and 4 has been proposed.

The forming equipment shown in these figures is a belt conveyor! A fixed outer cylinder 3 arranged above and having a large number of nozzles 2, and a rotor 5 rotatably fitted into the fixed outer cylinder 3 and having material delivery holes 4 matching the nozzle pitch of the fixed outer cylinder 3.
and a header 7 for supplying a fluid substance to a raw material inflow hole 6 formed on the side of the fixed outer cylinder 3.

In this molding device, by rotating the rotor 5 in the fixed outer cylinder 3, a part of the material delivery hole 4 of the rotor 5 and the raw material inflow hole 6 are aligned, and the other part of the material delivery hole 4 and the nozzle 2 are aligned. When these match, the fluid material is transferred to header 5.
The material is supplied into the material delivery hole 4 of the rotor 5 through the flow path 8 and the material inflow hole 6, and is further discharged from the material delivery hole 4 through the nozzle 2, and the fluid material is dripped onto the belt conveyor l. While being transported by the belt conveyor 1, it is cooled and becomes solid granules. Then, when the phase of the rotor 5 changes and each of the raw material inlet hole 6 and the nozzle 2 is in contact with the non-penetrating portion of the rotor 5, the discharge of the fluid material from the nozzle 2 is stopped.

This operation is repeated to continuously granulate the fluid material.

``Problem to be Solved by the Invention'' However, since the above-mentioned apparatus has a configuration in which the fluid substance is supplied from the lateral direction of the rotor, only one rotor can be provided per apparatus. There was a problem that productivity per unit was low.

In addition, in the above device, it is possible to install two rotors at the front and back in the belt traveling direction, but in this case, two containers for the fluid substance are required, which increases the size and cost of the device. Put it away.

Furthermore, conventional methods of supplying a fluid substance from above the molding device and discharging it downwards have not been implemented because the problem of difficulty in controlling granulation cannot be solved.

The present invention has been made in view of the above circumstances, and aims to provide a molding device in which a fluid substance can be supplied from the top and a plurality of rotors can be disposed.

This is a molding device that is provided with a nozzle body consisting of a nozzle holder that is slidably held in a part.

The present invention will be explained below using the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention, with reference numeral 1
1 is a molding device.

This molding device 11 includes a fixed frame 13 in which a plurality of spaces are formed into which three rotors 12 are fitted, and three rotors 12 which are rotatably fitted in the spaces.・
and is provided on the upper part of this fixed frame 13, and this fixed frame 13
The fluid substance storage container 14 has an upper surface as a bottom.

The rotor 12 is provided with an inlet 15 and an outlet 16 for the fluid substance on its circumferential surface, and a flow path 17 connecting the inlet 15 and the outlet 16 is formed inside the rotor 12. There is.

When the rotor inside the fixed frame 13 rotates and the inlet 15 is located at the upper part and the outlet 16 is located at the lower part, an upper population 1 is provided at the upper and lower parts of the fixed frame so as to communicate with these.
8 and a lower outlet 19 are provided. This upper entrance 1
8 is a fluid substance storage container 1 provided on the upper part of the fixed frame 13
It is formed with an opening in 4.

Furthermore, in each space of the fixed frame 13, a pipe-shaped sliding bearing 20 is provided.
... are fitted and fixed, and the rotor 12 ... is rotatably fitted into these sliding bearings 20 .... Through holes are formed at positions corresponding to the upper inlet 18 and lower outlet 19 of these sliding bearings 20, which correspond to the upper inlet 18 and the lower outlet 19.

Further, at the lower part of the fixed frame 13, a nozzle plate 22 having an opening 21 corresponding to the lower outlet 19 and this nozzle plate 22 are provided.
A nozzle body 24 is provided with a nozzle holder 23 that slidably holds the nozzle at the lower part of the fixed frame.

Further, a heat medium passage 25 is formed in the fixed frame 13 to pass a heat medium such as heated air or heated steam in order to heat or keep the fixed frame 13 warm. Note that the method of heating and keeping the fixed frame 13 warm is not limited to the above method using a heating medium, but may also be configured such that a heater is disposed within the fixed frame 13 to perform heating or keeping warm.

The fluid substance storage container 14 is a fixed frame! 3. The liquid levels of the container body 26 fixed to the upper surface, the fluid substance supply pipe 27 inserted into the container body 26, and the fluid substance 28 stored in the fluid substance storage container 14 are maintained at a constant level. The fluid material discharge pipe 29 is provided at a constant height of the container body 26. This container body 26
around the fluid substance 28 contained within the container body 26.
A heater 30 for heating or keeping warm is provided.

Inside this fluid substance storage container 14, a fluid substance supply pipe 27 is provided.
A fixed amount of fluid material 28 is always supplied through the fluid material 28, and when the amount of fluid material 28 exceeds a certain amount, the excess fluid material 28 is discharged out of the container through the fluid material discharge pipe 29, and the fluid material 28 is discharged from the container through the fluid material discharge pipe 29. The liquid level of the substance 28 is always kept constant.

By keeping the liquid level of the fluid substance 28 constant in this manner, the introduction pressure of the fluid substance 28 introduced into the upper inlet 18 formed as an opening on the upper surface of the fixed frame 13 can always be kept constant. Further, the pressure at which the fluid substance 28 is introduced into the upper inlet 18 is adjusted as appropriate by adjusting the arrangement position of the fluid substance discharge pipe 29 and changing the liquid level of the fluid substance 28, but the pressure inside the container body 26 is not increased. By doing so, the introduction pressure may be greater than the weight of the fluid material itself.

Note that the fluid substance 28 is a material that has fluidity, such as a melt of a heat-meltable substance such as a synthetic resin, wax, or hot-melt adhesive, and that solidifies under certain conditions such as cooling or leaving it naturally. It is used.

A belt conveyor 31 is provided below the nozzle body 24 of the fixed frame 13. This belt conveyor 31 runs in the same direction (indicated by an arrow in the figure) at approximately the same speed as the circumferential speed of the rotor 12, and is designed to solidify the fluid material 28 that has fallen onto this belt conveyor 31. It is preferable that it be cooled to . For this cooling, for example, a cooling method using water or air from the back side of the belt can be adopted. Furthermore, if the solidification temperature of the fluid material is considerably high, the fluid material may be sufficiently cooled and solidified even if the belt conveyor 31 is left at room temperature without being actively cooled. The distance between the belt conveyor 31 and the nozzle plate 22 of the fixed frame 13 is as follows:
It is preferable to set it in the range of 5 to 30 fflI11.

In order to mold a heat-fusible substance using the molding device 11 configured as described above, each rotor 12... is rotated at a predetermined speed, and the belt conveyor 3I is run at the same speed as the rotor 12... let Furthermore, a fluid material that has been heated and melted in advance is supplied into the fluid material storage container 14 from the fluid material supply pipe 27, and the liquid level of the fluid material 28 is maintained at a constant level.

The fluid substance 28 in the fluid substance storage container 14 passes through the flow path 17 to the nozzle when the inlet 15 of each rotor 12 overlaps with the upper inlet 18 of the fixed frame 13 and the outlet 16 and lower outlet 19 overlap. It is discharged from the opening 21 of the plate 22. The discharged fluid substance 28 falls on the belt conveyor 31 in the form of granules, and is cooled and solidified while being conveyed by the belt conveyor 31 to become solid granules.

After the discharge operation, each rotor 12...
The discharge of the fluid substance 28 is stopped while each of the inlet I5 and the outlet 16 is in contact with the non-penetrating portion of the fixed frame 13.

As described above, the operations of ejecting and stopping the ejection of the fluid material 28 from the nozzle body 24 are performed continuously, and solid granules are continuously produced.

In this forming device, the nozzle plate 22 of the nozzle body 24 is slid to adjust the degree of overlap between each opening 21 of the nozzle plate 22 and the lower outlet 19, and the actual size of the opening through which the fluid material 28 is discharged is adjusted. You can set the
Since the discharge amount of the fluid material 28 can be adjusted by sliding the nozzle plate 22, the fluid material 28 can be delivered to the rotor 1.
Even when the nozzle plate 22 is supplied from above, the granulation can be controlled by sliding the nozzle plate 22 and adjusting the actual size of the opening. Since the fluid substance 28 can be supplied from the top of the rotor, a plurality of rotors 12 can be arranged in parallel in the belt traveling direction.
By configuring the molding device 11 by arranging a plurality of rotors 12 in parallel, the productivity of the molding device 11 can be greatly improved.

In addition, the path for the fluid material 28 to be discharged from the fluid material storage container 14 to the outside of the molding device 11 to become particles can be shortened, and the number of flow paths that require heating can be reduced compared to conventional devices. cleaning work can be facilitated.

In the previous example, the granules were produced by rotating the rotor at a constant circumferential speed, but the rotor was stopped with the inlet and upper inlet, and the outlet and lower outlet completely or partially aligned. By doing so, it is also possible to produce a linear object in which the fluid substance is solidified into a linear shape.

"Effects of the Invention" As explained above, the molding apparatus according to the present invention has the above-mentioned configuration, thereby achieving the following effects.

By attaching the nozzle body to the lower part of the fixed frame and making it possible to adjust the size of the opening as desired by sliding the nozzle plate, granulation control can be performed even when the fluid substance is supplied from the upper part of the rotor. Therefore, a forming apparatus can be constructed by arranging a plurality of rotors in parallel in the belt traveling direction, and the productivity of the forming apparatus can be greatly improved.

In addition, by supplying the fluid material from the top of the rotor, the path for the fluid material to be discharged from the storage container to the outside of the molding device and become particles can be shortened, and the flow path that requires heating can be shortened compared to the conventional device. It is possible to reduce the amount by more than 100 yen, and the cleaning work of the device can be made easier.
