Description

Technical Field

[0001] The utility model relates to the technical field of foaming machines, in particular to a heating pre-foaming device for foaming microsphere powder. Background Art

[0002] The pre-foaming machine is a device specially used for pre-treating foamed microspheres. The pre-foaming machine is mainly divided into steam pre-foaming machine and electric steam pre-foaming machine. The steam pre-foaming machine mainly heats the microsphere powder through steam. After pre-foaming, it can be used after being naturally air-dried and placed for 24 hours. The electric steam pre-foaming machine uses electric heating as the main method and steam heating as the auxiliary method for mixed heating. The foamed microsphere powder can be used after being placed for 4-6 hours after pre-foaming.

[0003] The electric steam pre-foaming machine is mainly composed of a feeding system, a control system, a pressurized foaming barrel and a discharging system. An electric heating device is provided on the outside of the pressurized foaming barrel to heat the barrel. When the electric steam pre-foaming machine is working, the feeding system feeds the quantitative foaming microsphere powder into the pressurized foaming barrel, and then heats the pressurized foaming barrel through the control system. After heating, the air is exhausted to avoid high air pressure in the barrel, and then the foaming microsphere powder in the barrel is stirred and foamed. After pre-foaming, the foaming microsphere powder is discharged through the discharging system.

[0004] During the stirring and foaming process of the foaming microsphere powder, the stirring device in the pressurized foaming barrel will cause uneven stirring when stirring the foaming microsphere powder, which will cause the foaming microsphere powder to fail to move fully, thereby resulting in the appearance of unfoamed particle clusters, resulting in a reduction in the pre-foaming effect and affecting the pre-foaming quality of the foaming microsphere powder.

[0005] To this end, the prior art has proposed a microsphere foaming powder heating pre-foaming device, which uses the cooperation of a telescopic mechanism and a rotating mechanism to pre-clear the material at the foaming machine discharge port, thereby avoiding residual foaming material at the foaming machine discharge port, which causes the material to spill on the ground when the device is opened, resulting in waste. However, the problem of agglomeration of foamed microsphere powder caused by uneven stirring has not been solved.

[0006] In view of this, we propose a heating pre-foaming device for foaming microsphere powder. Utility Model Content

[0007] The purpose of the utility model is to provide a device for heating and pre-foaming foamed microsphere powder to solve the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] The axle up and down groove at two ends embeds respectively in two guide rails up and down of being made up of the groove on the attachment piece, and the tooth on the attachment piece is meshed with tooth on upper sprocket wheel, the lower sprocket. The tooth on the attachment piece is meshed with tooth on upper sprocket. The connected crank rotates, and the crank drives the stirring blade to rotate around the rotating shaft, so that the stirring blade performs a circular motion in a small range, thereby enhancing the stirring effect of the stirring blade, thereby promoting the pre-foaming effect. At the same time, the rotating shaft drives the stirring blade to revolve around the stirring shaft through the crank, thereby increasing the stirring range of the stirring blade, avoiding the generation of dead angles, and enhancing the uniformity of stirring. A driven wheel is fixedly installed on the top of the stirring blade; the driven wheel is located on the upper end surface of the crank, and an outer gear ring is provided on the outer side of the driven wheel; the outer gear ring is fixedly installed at the bottom end of the rotating bracket, and the outer gear ring is coaxially installed with the transmission wheel. When the stirring blade performs a circular motion around the rotating shaft, the driven wheel fixed thereon meshes with the transmission wheel, thereby driving the stirring blade to rotate on its own, thereby promoting stirring intensity and enhancing foaming efficiency. During the rotation of the driven wheel, it maintains stable operation under the action of the outer gear ring, and the outer gear ring plays a limiting role in the movement of the driven wheel.

[0011] Preferably, the fixed wheel is connected to the stirring shaft through a bearing, and the fixed wheel is fixedly connected to the top of the foaming chamber. The fixed wheel is connected to the stirring shaft through a bearing, so that it does not rotate synchronously with the stirring shaft.

[0013] Preferably, the stirring shaft is an L-shaped structure as a whole, and the L-shaped structure is divided into a vertical section and a horizontal section. The vertical section of the stirring shaft stirs the foaming microsphere powder at different heights, and the horizontal section of the stirring shaft stirs the foaming microsphere powder at the bottom of the foaming chamber to avoid the foaming microsphere powder from accumulating at the bottom, causing the temperature of the bottom of the foaming chamber to rise, and then causing the foaming quality to decrease, affecting the foaming effect.

[0014] Preferably, the stirring blade is provided with an inclined surface, which is used to reduce the interaction force between the stirring blade and the foaming microsphere powder, thereby increasing the stirring intensity of the stirring blade and ensuring that the foaming microsphere powder can be uniformly stirred and foamed.

[0015] Preferably, the stirring blade is provided with arcuate lines, which enable the stirring blade to flip the foamed microsphere powder in the vertical direction during rotation, thereby enhancing the stirring effect of the foamed microsphere powder and ensuring the quality of stirring and foaming.
