Description

Technical Field

[0001] The invention belongs to the technical field of polyurethane material processing, in particular to an emulsifying device for processing waterborne polyurethane material. Background Art

[0002] Emulsification equipment for waterborne polyurethane material processing is a kind of equipment specially used to disperse high molecular polymers (such as waterborne polyurethane) into water; At present, the traditional emulsification equipment for processing waterborne polyurethane materials is to add the polyurethane raw materials into the emulsification tank, then start the stirring device to make the materials start preliminary mixing in the tank, and then use the high-speed rotating stirring paddle to produce strong shearing, impact and cavitation effects on the materials, so that the waterborne polyurethane resin raw materials gradually form a stable emulsion in the water; However, in actual use, in order to quickly discharge the emulsified emulsion, the discharge pipe of the emulsification tank is set at the bottom of the emulsification tank. When the raw materials are added to the emulsification tank, due to the effects of gravity and fluidity, they are easy to enter and deposit inside the discharge pipe. This is particularly evident when adding viscous or large-particle polyurethane raw materials. Once the raw materials enter the discharge pipe, they may be ignored during the emulsification process or fail to receive sufficient shear, impact and cavitation. This is because the stirring device and high-speed rotating stirring paddle in the emulsification tank mainly act on the material in the tank body, and it is difficult to effectively emulsify the raw materials that have been deposited inside the discharge pipe, which reduces the uniformity and quality of the product.

Under this low-pressure state, the air inside the polyurethane is squeezed out. Finally, the worm screw 1 is linked to the fan blades to reduce the air pressure inside the emulsification tank, thereby squeezing out the air inside the polyurethane, making the polyurethane raw material denser and more uniform.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 7 As shown, the present invention provides an emulsification device for processing waterborne polyurethane materials, comprising a main body 1, an emulsification tank 2 is arranged inside the main body 1, a discharge pipe 3 is arranged at the bottom end of the emulsification tank 2, and the discharge pipe 3 is connected with the emulsification tank 2; An emulsifying mechanism, which is arranged inside the main body 1; A sealing mechanism is arranged inside the emulsification tank 2, and includes a fixed shell 4, which is fixedly connected to the inside of the emulsification tank 2, a spring 5 is fixedly installed inside the fixed shell 4, a sealing plate 6 is fixedly installed at one end of the spring 5, a belt 7 is fixedly installed on one side of the sealing plate 6, a motor 8 is fixedly installed inside the fixed shell 4, a winding disk 9 is fixedly installed at the output end of the motor 8, and one end of the belt 7 is fixedly connected to the surface of the winding disk 9.

[0019] The above scheme is adopted: the operator drives the motor 8 to rotate the winding disk 9, and then the belt 7 wound on the surface of the winding disk 9 is unwound, and then the compressed spring 5 pushes the blocking plate 6 to move, and then the blocking plate 6 moves to the top of the discharge pipe 3, thereby blocking the discharge pipe 3; At this time, the polyurethane raw material can be poured into the interior of the emulsification tank 2, and then the emulsification mechanism can be driven to emulsify it. After the emulsification is completed, the motor 8 can be driven again to rotate the winding disk 9. During the rotation of the winding disk 9, the belt 7 will be wrapped around its surface, and then the moving belt 7 will pull the sealing plate 6 to slide toward the inside of the fixed shell 4. When the sealing plate 6 moves, the spring 5 will be compressed, and then the sealing plate 6 will cancel the blockage of the discharge pipe 3, and then the discharge pipe 3 can be opened to discharge the emulsified product from the interior of the emulsification tank 2. Finally, the sealing plate 6 is driven by the motor 8 to block the discharge pipe 3, thereby preventing the material from entering the inside of the discharge pipe 3 when adding the polyurethane raw material, ensuring that all polyurethane raw materials can be effectively emulsified, thereby improving the uniformity and quality of the product.

[0020] like Figure 1 , Figure 2 and Figure 5As shown, the emulsifying mechanism includes an electric push rod 10, a mounting plate 11 is fixedly installed on the top end of the electric push rod 10, a sealing cover 12 is fixedly installed on the bottom end of the mounting plate 11, a motor 13 is fixedly installed inside the mounting plate 11, a stirring paddle 14 located inside the sealing cover 12 is fixedly installed on the output end of the motor 13, and the stirring paddle 14 can rotate inside the sealing cover 12, a worm 17 is fixedly installed on the surface of the stirring paddle 14, and a cutting assembly 15 located on the surface of the stirring paddle 14 is fixedly installed inside the sealing cover 12.

[0021] The above scheme is adopted: through the design of the emulsification mechanism, after the polyurethane raw material is added, the electric push rod 10 can be driven so that its output shaft pulls the mounting plate 11 down, and the mounting plate 11 will drive the sealing cover 12, the motor 2 13, the stirring paddle 14 and the cutting assembly 15 to enter the interior of the emulsification tank 2, and the sealing cover 12 will be sleeved on the top of the emulsification tank 2, so that the emulsification tank 2 enters a sealed state, and then the motor 2 13 can be driven to rotate the stirring paddle 14. Since the stirring paddle 14 and the cutting assembly 15 are staggered in design, the polyurethane can be emulsified through the cooperation between the stirring paddle 14 and the cutting assembly 15.

[0022] like Figure 5 , Figure 6 and Figure 7 As shown, it also includes: a removal mechanism, which is arranged on the surface of the sealing cover 12, the removal mechanism includes an exhaust pipe 16, the exhaust pipe 16 is fixedly connected to the surface of the sealing cover 12, a fixed plate 18 is fixedly installed inside the exhaust pipe 16, a rotating rod 19 is rotatably connected inside the fixed plate 18, a fan blade 20 is fixedly installed on the top end of the rotating rod 19, a worm gear 21 is fixedly installed on the bottom end of the rotating rod 19, a support plate 22 is fixedly installed inside the sealing cover 12, a rotating rod 23 is rotatably connected inside the support plate 22, a worm gear 21 meshing with the worm 17 is fixedly installed on one end of the rotating rod 23, a worm gear 23 meshing with the worm 17 is fixedly installed on the other end of the rotating rod 23, and a one-way valve 24 is arranged inside the exhaust pipe 16.

[0023] The above scheme is adopted: by removing the design of the mechanism, when the stirring paddle 14 rotates, the worm 17 will rotate accordingly, because the worm 17 is meshed with the worm gear 2 31, and then the rotating worm 17 will drive the worm gear 2 31 to rotate, and the worm gear 2 31 will drive the movable rod 23 and the worm 2 32 to rotate, because the worm 2 32 is meshed with the worm gear 1 21, and then the rotating worm 2 32 will drive the worm gear 1 21 to rotate, and the worm gear 1 21 will drive the rotating rod 19 and the fan blade 20 to rotate, and the rotation of the fan blade 20 will generate suction, which will draw the air inside the emulsification tank 2 into the exhaust pipe 16, and then the air entering the exhaust pipe 16 will be discharged from the inside of the one-way valve 24, and in the process of discharge, the air pressure inside the emulsification tank 2 will decrease, and under this low-pressure state, the air inside the polyurethane will be squeezed out, and finally the worm 17 will link the fan blade 20 to reduce the air pressure inside the emulsification tank 2, so that the air inside the polyurethane is squeezed out, making the polyurethane raw material more dense and uniform.

[0024] like Figure 7 As shown, two limiting rings 25 are fixedly mounted on the surface of the rotating rod 19 , and opposite sides of the limiting rings 25 are in contact with the surface of the fixing plate 18 .

[0025] The above scheme is adopted: through the design of the limit ring 25, when the rotating rod 19 rotates, the limit ring 25 will rotate accordingly. Since the opposite sides of the limit ring 25 are in contact with the surface of the fixed plate 18, the limit ring 25 can be limited and supported when it rotates, ensuring that the rotating rod 19 can rotate normally.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the interior of the fixed shell 4 is rotatably connected with a protective pulley 26, and the surface of the belt 7 contacts the surface of the protective pulley 26. An observation plate 27 is fixedly installed on one side of the surface of the emulsification tank 2, and the observation plate 27 is made of a transparent material.

[0027] The above scheme is adopted: through the design of the protective pulley 26, when the winding disk 9 pulls the belt 7 to move, the friction between the protective pulley 26 and the protective pulley 26 will cause the protective pulley 26 to rotate, and then the protective pulley 26 can protect the moving belt 7 to reduce the wear of the belt 7. Through the design of the observation plate 27, since the observation plate 27 is made of transparent material, during the emulsification process, the operator can observe the emulsification effect of the material inside the emulsification tank 2 through the observation plate 27.

[0028] like Figure 1 As shown, a roller 28 is fixedly installed at the bottom end of the main body 1 , and the number of rollers 28 is four and all distributed at the bottom end of the main body 1 . A platform 29 is fixedly installed at one side of the main body 1 , and a ladder 30 is fixedly installed at one side of the platform 29 .

[0029] Adopting the above scheme: through the design of the roller 28, the operator can push the equipment to make the roller 28 rotate, and then the rotating roller 28 will drive the entire equipment to move, and then through the rotation of the roller 28, it is convenient for the operator to move the equipment. Through the design of the platform 29 and the ladder 30, the operator can stand on the top of the ladder 30 along the platform 29, which makes it convenient for the operator to add polyurethane to the inside of the emulsification tank 2.

[0030] like Figure 3 , Figure 5 and Figure 7 As shown, the surface of the blocking plate 6 fully fits with the inner wall of the emulsifying tank 2, and the surface of the blocking plate 6 fully fits with the surface of the fixed shell 4. The fixed plate 18 is square in design, and the bottom end is triangular in design.

[0031] The above-mentioned scheme is adopted: through the design of the sealing plate 6, the surface of the sealing plate 6 is in contact with the inner wall of the emulsification tank 2, thereby improving the sealing effect, and the surface of the sealing plate 6 is in contact with the surface of the fixed shell 4, thereby preventing polyurethane from entering the interior of the fixed shell 4. Through the design of the fixing plate 18, since the bottom end of the fixing plate 18 is triangular in design, its resistance can be reduced, thereby allowing air to enter the interior of the exhaust pipe 16 more smoothly.

[0032] The working principle and use process of the present invention: First, the operator drives the motor 8 to rotate the winding disk 9, so that the belt 7 wound on the surface of the winding disk 9 is unwound, and then the compressed spring 5 pushes the blocking plate 6 to move, and the blocking plate 6 moves to the top of the discharge pipe 3, thereby blocking the discharge pipe 3; At this time, the polyurethane raw material can be poured into the emulsification tank 2. After the addition is completed, the electric push rod 10 is driven to make its output shaft pull the mounting plate 11 downward, and the mounting plate 11 will drive the sealing cover 12, the motor 2 13, the stirring paddle 14 and the cutting assembly 15 to descend, and the emulsification tank 2 enters a sealed state, and then the motor 2 13 can be driven to rotate the stirring paddle 14, so that the polyurethane can be emulsified; When the stirring paddle 14 rotates, the worm 17 will rotate accordingly, and the worm 17 will drive the worm wheel 2 31, the rotating rod 23 and the worm 2 32 to rotate, and the worm 2 32 will drive the worm wheel 21, the rotating rod 19 and the fan blade 20 to rotate. The rotation of the fan blade 20 will generate suction, and the air inside the emulsification tank 2 will be sucked into the exhaust pipe 16. Then, the air entering the exhaust pipe 16 will be discharged from the inside of the one-way valve 24. In the process of discharge, the air pressure inside the emulsification tank 2 will decrease. Under this low pressure state, the air inside the polyurethane will be squeezed out. After the emulsification is completed, the motor 8 can be driven again to rotate the winding disk 9. During the rotation of the winding disk 9, the belt 7 will be wrapped around its surface, and then the moving belt 7 will pull the sealing plate 6 to slide toward the inside of the fixed shell 4. When the sealing plate 6 moves, the spring 5 will be compressed, and then the sealing plate 6 will cancel the blockage of the discharge pipe 3. Then the discharge pipe 3 can be opened, and then the valve on the surface of the discharge pipe 3 is opened, so that the emulsified product can be discharged from the inside of the emulsification tank 2, and finally the operation process is completed.
