Description

Heat Wax Cooling Molding Machine that effectively removes paraffin wax accumulated on the scraper to increase production efficiency

The present invention relates to a hot wax cooling molding apparatus that effectively removes paraffin wax accumulated on a scraper to increase production efficiency.

Flaker usually consists of a support, a roller and a scraper on the support, and its main function is to continuously cool and solidify high-temperature paraffin wax on the surface of the flaker roller, and the scraper of the flaker applies the cooled paraffin wax to the roller.

The upper end of the pedestal 10 is fixedly connected to the bottom plate 5 , and the lower end of the pedestal 10 is fixedly connected to the push rod 6 .

In order to prevent the paraffin wax from adhering to the upper surface of the scraper 3 , a PTFE paint layer is applied to the upper surface of the scraper 3 . A discharge hopper was installed under the scraper (2) to collect the paraffin wax scraped by the scraper (3).

When working, the upper surface of the upper plate (5) is placed in line with the upper surface of the scraper (3), and when paraffin wax is accumulated on the upper surface of the scraper, the cylinder (9) works to straighten the piston rod and turn the push board (7), and push The board (7) pushes the push rod (6), the push rod (6) moves the pedestal (10) to push the top plate (5), and the top plate (5) moves upward to separate the paraffin wax from the top surface of the scraper (3) , when the cylinder (9) piston rod contracts, the top plate (5) moves downward in the groove of the scraper (3), making the top surface of the top plate (5) lower than the top surface of the scraper (2), so that paraffin wax passes through the top surface of the scraper (3) and the top plate (5) ), the paraffin wax is completely separated and falls into the discharge hopper, and the cylinder (9) continues to move and the top plate (5) returns to its original position so that the top surface of the top plate (5) and the top surface of the scraper (3) are laid out.

Therefore, there is an advantage in that the work efficiency is increased and the labor cost is reduced.

On the other hand, in a modified example (not shown) of the warm wax cooling molding apparatus of the present invention, the hot wax that has undergone a pretreatment process (to ensure a homogeneous fluid wax) of stirring and heating by a mixer (not shown) is supplied to the cooling roller. can The mixer includes a chamber in which the fluid wax is loaded, a burner disposed on the side of the chamber to heat the chamber, a phase sensor sensing the surface height of the fluid wax in the chamber, and a first stirring unit disposed inside the chamber; , a second stirring unit disposed inside the chamber and disposed below the first stirring unit, and an electronic control unit receiving a signal from a phase sensor to control the first stirring unit and the second stirring unit. can

In this case, the first stirring unit includes a first blade, a first shaft forming a rotation shaft of the first blade, a first rotation motor rotating the first shaft, and moving the first rotation motor in a vertical direction It may include a first step motor. In addition, the second stirring unit includes a second blade, a second shaft forming a rotation shaft of the second blade, a second rotation motor rotating the second shaft, and vertically moving the second rotation motor A second step motor may be included. Furthermore, the first blade and the second blade may be disposed to face each other in a vertical direction.

In the mixer, when the fluid wax is loaded in the chamber, the phase sensor may measure the height of the surface to generate a sensed value. The electronic control unit receives the sensing value from the phase sensor and controls the first step motor to position the first blade on the upper side with respect to the center plane in the vertical direction of the surface, so that the first blade and the first shaft are The first rotary motor can be moved in a vertical direction, and the second blade and the second shaft are formed by controlling the second step motor so that the second blade is located on the lower side with respect to the central plane in the vertical direction of the water surface. The second rotation motor may be moved in a vertical direction. Then, the electronic control unit may control the first rotation motor and the second rotation motor to rotate the first blade and the second blade to rotate in mutually different directions. As a result, in the mixer, vortexes in opposite directions are formed on each of the upper and lower sides of the chamber to increase the stirring efficiency.

In addition, at the ends of the first blade and the second blade, a first shape memory alloy having a length in one direction at a first temperature or higher and a second shape memory alloy having a length in one direction at a second temperature higher than the first temperature are sequentially may be stacked and disposed (a connection member may be disposed between the first shape memory alloy and the second shape memory alloy).

Therefore, in the present invention, when the temperature in the chamber rises above the first temperature during heating by the burner, the length of the first blade and the second blade increases by the shape change of the first shape memory alloy at the end, increasing the stirring efficiency to promote the convection phenomenon. , it is possible to prevent excessive thermal deformation of the fluid wax by intensive heating on the burner side. In addition, when the temperature in the chamber rises above the second temperature, the length of the first blade and the second blade increases as much as the shape change of the second shape memory alloy at the end, thereby increasing the stirring efficiency and promoting the convection phenomenon more actively, Likewise, it is possible to prevent excessive thermal deformation of the fluid wax due to intensive heating on the burner side.

Furthermore, when the first blade and the second blade are rotated, when the value sensed by the phase sensor exceeds the reference value, the electronic control unit determines that the rotation of the first blade and the second blade is dominant and the height of the surface is increased. It is determined that the rotation speed of the first blade and the second blade can be reduced to be slower than the current operating speed, and by controlling the burner to increase the output of the burner than the current output, that is, the temperature in the chamber is reduced to the first temperature. It is possible to quickly activate the first shape memory alloy and the second shape memory alloy of the first blade and the second blade by raising the temperature from less than to the second temperature (compensating for agitation efficiency reduced by the rotational speed).
