Description

Technical Field

[0001] The utility model relates to the technical field of foaming devices, in particular to an expandable microsphere foaming device. Background Technique

[0002] The expandable microsphere foaming device is suitable for expanding and foaming microspheres. By introducing raw materials into a container for heating and then introducing an inert gas, the microspheres can be foamed to a certain volume without damaging the outer shell.

[0003] Due to the limitations of the foaming device in the existing microsphere foaming technology, there are problems such as uneven heating of microspheres and adhesion of microspheres. The microspheres far from the heat source foam slowly and do not reach the maximum foaming volume, while the microspheres close to the heating area foam faster or even shrink. Therefore, the phenomenon of uneven microsphere foaming occurs. For this reason, we propose an expandable microsphere foaming device. Content of the Utility Model

[0004] The purpose of the utility model is to provide an expandable microsphere foaming device, which can achieve uniform heating of microspheres during foaming and has a better foaming effect.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an expandable microsphere foaming device, including a device box, a collection box, and a screw conveyor. The device box further includes a foaming chamber integrally formed inside. Air ports are respectively arranged on both sides of the device box. A stirring motor is fixedly installed at one end of the device box. A synchronization mechanism is arranged between the output end of the stirring motor and the screw conveyor.

Belt pulleys are respectively fixedly sleeved on the output end of the stirring motor and the end of the spiral blade shaft inside the screw conveyor, and the two belt pulleys are synchronously driven by the belt. A machine box is fixedly installed in the middle of the inner cavity of the foaming chamber. Longitudinal stirring blades and transverse stirring blades are respectively rotatably installed around the machine box through rotating shafts.

[0006] Preferably, a control panel is fixedly installed on the front of the device box, and the two air ports are respectively used for introducing and discharging inert gas.

[0007] Preferably, a discharge pipe is connected through between the collection box and the foaming chamber. One end at the top of the screw conveyor is connected through with a feed hopper, and the other end at the top of the screw conveyor is connected through with a feed pipe. The bottom end of the feed pipe extends into the inner cavity of the foaming chamber.

[0008] Preferably, a first connecting frame is fixedly installed between the stirring motor and the device box, and second connecting frames are respectively fixedly installed between the front and rear sides of the machine box and the inner wall of the foaming chamber.

At the same time, after the inert gas introduced through the air port is stirred in multiple dimensions, it can prevent the microspheres from foaming and adhering to the inner wall of the foaming chamber in a large area after heating. The stirring blades are provided with a grid structure to increase the contact surface of the microspheres, ensuring that the microspheres are evenly heated and expanded, solving the problems of uneven heating of the microspheres and adhesion of the microspheres.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: an expandable microsphere foaming device, including a device box 1, a collection box 2, and a screw conveyor 3. The device box 1 further includes a foaming chamber 12 integrally formed inside. Air ports 13 are respectively arranged on both sides of the device box 1. A stirring motor 4 is fixedly installed at one end of the device box 1. A synchronization mechanism 41 is arranged between the output end of the stirring motor 4 and the screw conveyor 3. The synchronization mechanism 41 includes a belt and belt pulleys;

[0020] Belt pulleys are respectively fixedly sleeved on the output end of the stirring motor 4 and the end part of the spiral blade shaft inside the screw conveyor 3, and the two groups of belt pulleys are synchronously driven by a belt. A machine box 5 is fixedly installed in the middle of the inner cavity of the foaming chamber 12. Longitudinal stirring blades 6 and transverse stirring blades 7 are respectively rotatably installed around the machine box 5 through rotating shafts;

[0021] By feeding the microsphere foaming raw material into the foaming chamber 12 through the screw conveyor blade in the screw conveyor 3 through the feed hopper 31, and under the heating of the electric heating blocks on the inner wall of the foaming chamber 12, the microspheres are foamed. At the same time, the stirring blades can stir the foamed microspheres. This foaming technology solution of the foamed microspheres is a prior art and will not be elaborated here;

[0022] The circumferential surface of the cylindrical foaming chamber 12 is covered with electric heating blocks, so that the foaming balls can be widely contacted. The output end of the stirring motor 4 drives the transverse stirring blade 7 and the second bevel gear 71 on the end rotating shaft to rotate, so that the two groups of first bevel gears 61 and the other group of second bevel gears 71 rotate synchronously, so that the two groups of transverse stirring blades 7 and the two groups of longitudinal stirring blades 6 can rotate in multiple dimensions in the foaming chamber 12, so that the microspheres can be evenly distributed on the inner wall of the foaming chamber 12. At the same time, the inert gas introduced through the air port 13 can avoid large-area adhesion of the microspheres after foaming and heating on the inner wall of the foaming chamber 12. The stirring blades are provided with a grid structure to increase the contact surface of the microspheres and ensure that the microspheres are evenly heated and expanded.

[0023] Among them, a control panel 11 is fixedly installed on the front of the device box 1. The two air ports 13 are respectively used for introducing and discharging inert gas. The inert gas is introduced and discharged through the air ports 13 on both sides of the foaming chamber 12, so that the inert gas prevents the microspheres from adhering to the foaming chamber 12 during foaming.

[0024] Among them, a discharge pipe 21 is connected through between the collection box 2 and the foaming chamber 12. One end of the top of the screw conveyor 3 is connected through with a feed hopper 31, and the other end of the top of the screw conveyor 3 is connected through with a feed pipe 32. The bottom end of the feed pipe 32 extends into the inner cavity of the foaming chamber 12. By using a VTOPS-F114R screw conveyor, a large amount of microsphere raw materials can be evenly dispersed and introduced into the foaming chamber 12.

[0025] Among them, a first connecting frame 42 is fixedly installed between the stirring motor 4 and the device box 1. Second connecting frames 51 are respectively fixedly installed between the front and rear sides of the chassis 5 and the inner wall of the foaming chamber 12. The end shafts of the two sets of transverse stirring blades 7 close to the side of the chassis 5 are fixedly connected, and a second bevel gear 71 is fixedly sleeved on the end shaft of the transverse stirring blade 7 close to the side of the stirring motor 4. First bevel gears 61 are respectively fixedly sleeved on the adjacent end shafts of the two sets of longitudinal stirring blades 6, and the outer edges of the two sets of first bevel gears 61 are respectively meshed with the outer edge of the second bevel gear 71. The transverse stirring blades 7 and the longitudinal stirring blades 6 are both of grid structures. The foaming chamber 12 is of a cylindrical structure, and an electric heating block is fixedly installed on the inner wall of the foaming chamber 12. By driving the transverse stirring blades 7 and the second bevel gear 71 on the end shaft by the output end of the stirring motor 4, the two sets of first bevel gears 61 and the other set of second bevel gears 71 rotate synchronously, so that the two sets of transverse stirring blades 7 and the two sets of longitudinal stirring blades 6 can rotate in multiple dimensions in the foaming chamber 12, so that the microspheres can be evenly distributed on the inner wall of the foaming chamber 12.

[0026] Working principle: When in use, first, the microsphere foaming raw materials are introduced into the foaming chamber 12 through the screw conveyor blades in the screw conveyor 3 via the feed hopper 31;

[0027] Then, by driving the transverse stirring blades 7 and the second bevel gear 71 on the end shaft by the output end of the stirring motor 4, the two sets of first bevel gears 61 and the other set of second bevel gears 71 rotate synchronously, so that the two sets of transverse stirring blades 7 and the two sets of longitudinal stirring blades 6 can rotate in multiple dimensions in the foaming chamber 12, so that the microspheres can be evenly distributed on the inner wall of the foaming chamber 12. At the same time, after the inert gas introduced through the air port 13 is stirred in multiple dimensions, it can prevent the microsphere foaming from adhering to a large area after heating with the inner wall of the foaming chamber 12. The stirring blades are provided with grid structures to increase the contact surface of the microspheres and ensure that the microspheres are evenly heated and expanded;

[0028] Finally, the foamed microspheres can be introduced into the collection box 2 through the discharge pipe 21 for collection.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes and modifications can be made to these embodiments without departing from the principle of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
