Abstract

This application relates to a high-efficiency production equipment for polyetheramine-modified epoxy resin coatings, belonging to the technical field of coating production equipment, which includes a mixing tank. This application achieves bidirectional shear mixing by setting up a rotating rod, spiral stirring blades, a rotating cylinder, a C-shaped rotating frame, and a stirring rod, thereby improving the uniformity of coating mixing.

Description

Technical Field

[0001] This application relates to the field of coating production equipment technology, and in particular to a high-efficiency production equipment for polyetheramine modified epoxy resin coatings. Background Technology

[0002] In recent years, solvent-free reinforced coatings have seen a continuous increase in demand in the construction, automotive, and shipbuilding industries due to their low VOC emissions and environmental friendliness. Among them, polyetheramine-modified epoxy resin high-toughness coatings have become a research hotspot due to their excellent mechanical properties. However, existing coating production equipment faces significant technical bottlenecks in preparing such solvent-free coatings: traditional stirring mechanisms mostly adopt a unidirectional stirring mode, which easily leads to local agglomeration and uneven dispersion when mixing high-viscosity raw materials, directly affecting the stability of the coating's mechanical properties; at the same time, the equipment lacks the ability to monitor the material mixing state in real time, and the motor speed is mostly set at a fixed value, unable to be dynamically adjusted according to parameters such as material viscosity and mixing uniformity, resulting in energy waste and extended production cycles, making it difficult to meet the needs of efficient and low-consumption industrial production. Therefore, there is an urgent need for a specialized equipment that can achieve uniform mixing through structural optimization and improve production efficiency through intelligent control. To this end, a high-efficiency production equipment for polyetheramine-modified epoxy resin coatings is provided. Utility Model Content

[0003] The purpose of this application is to provide a high-efficiency production equipment for polyetheramine modified epoxy resin coatings, which solves the problem of uneven mixing caused by traditional unidirectional stirring and improves production efficiency by combining intelligent control.

[0004] This application provides a high-efficiency production equipment for polyetheramine-modified epoxy resin coatings, employing the following technical solution: It includes a mixing tank, with a motor housing fixedly connected to the upper surface of the mixing tank. Inside the motor housing are fixed forward and reverse motors and a C-shaped base, with the C-shaped base positioned at the right end of the forward and reverse motors. The output end of the forward and reverse motors is rotatably connected to the inside of the C-shaped base and fixedly connected to a main bevel gear. The upper and lower ends of the right side of the main bevel gear are meshed with a first driven bevel gear and a second driven bevel gear. A rotating rod is fixedly connected inside the first driven bevel gear, with its upper end rotatably connected to the upper surface inside the C-shaped base. A rotating cylinder is fixedly connected to the lower end of the second driven bevel gear. The rotating cylinder is rotatably connected to the lower surface of the C-shaped base. The rotating rod is rotatably connected to the inside of the mixing tank through the upper surface of the mixing tank. The lower end of the rotating rod passes through the second bevel gear and the rotating cylinder and is rotatably connected to the inside of the mixing tank. A spiral stirring blade is fixedly connected to the lower end surface of the rotating rod. C-shaped rotating frames are fixedly connected to both sides of the lower end surface of the rotating cylinder. Stirring rods are fixedly connected to the two sets of C-shaped rotating frames near the spiral stirring blades. Mounting holes are opened inside both sides of the mixing tank. Infrared sensors are fixedly connected inside the mounting holes. A transparent wear-resistant plate is fixedly connected to the mounting holes near the inside of the mixing tank. The infrared sensors and the forward and reverse motors are electrically connected to an external controller. The output speed of the forward and reverse motors is adjusted according to the detection data of the infrared sensors. By adopting the above technical solution, and by setting up forward and reverse motors, a main bevel gear, a first driven bevel gear, a second driven bevel gear, a rotating rod, a rotating cylinder, a spiral stirring blade, a C-shaped rotating frame, a stirring rod, an infrared sensor, a transparent wear-resistant plate, and an external controller, several beneficial effects are achieved: the forward and reverse motors drive the rotating rod and rotating cylinder to rotate in opposite directions via the bevel gear set, so that the spiral stirring blade and the stirring rod form a bidirectional shearing action, solving the problem of uneven mixing in traditional unidirectional stirring and improving the uniformity of coating mixing; the infrared sensor monitors the material status in real time through the transparent wear-resistant plate, and the external controller adjusts the speed of the forward and reverse motors accordingly to achieve dynamic adaptation, reduce energy waste, shorten the production cycle, and meet the high-efficiency production requirements of solvent-free high-viscosity coatings.

[0005] Preferably, the upper end of the mixing tank is fixedly connected to a feed inlet, the lower end of the mixing tank is fixedly connected to a discharge outlet, and a solenoid valve is provided on the surface of the discharge outlet.

[0006] By adopting the above technical solution, and by setting up an inlet, an outlet, and a solenoid valve, the material entering and leaving the mixing tank becomes more convenient and controllable: the inlet facilitates the centralized input of raw materials, and the outlet, in conjunction with the solenoid valve, can precisely control the timing and speed of finished product discharge, reduce manual operation, adapt to automated production processes, and improve production continuity.

[0007] Preferably, a connecting cap is rotatably connected to the lower surface of the rotating rod, and the lower ends of the two sets of C-shaped rotating frames are fixedly connected to the left and right sides of the connecting cap.

[0008] By adopting the above technical solution and setting a connecting cap to connect the rotating rod to two sets of C-shaped rotating frames, the structural stability of the stirring component is enhanced: the radial swaying when the rotating rod and the rotating cylinder rotate in opposite directions is limited, the collision or abnormal gap between the spiral stirring blade and the stirring rod due to swaying is avoided, the service life of the equipment is extended, and the stirring effect is ensured to be stable.

[0009] Preferably, the spiral stirring blades and stirring rods are made of stainless steel and their surfaces are coated with a polytetrafluoroethylene wear-resistant layer.

[0010] By adopting the above technical solution, the spiral stirring blade and stirring rod are made of stainless steel and coated with a polytetrafluoroethylene wear-resistant layer, which brings multiple advantages: the stainless steel material ensures the strength of the components and can withstand the stirring resistance of high viscosity materials; the polytetrafluoroethylene wear-resistant layer reduces paint adhesion, reduces cleaning difficulty, and at the same time improves the wear resistance of the components, avoiding the impact of wear on the stirring effect due to long-term use, and adapts to the chemical properties of the paint, preventing the material from contaminating the paint.

[0011] Preferably, a mechanical seal is provided at the rotational connection between the rotating cylinder and the upper surface of the mixing tank.

[0012] By adopting the above technical solution and installing a mechanical seal at the rotating connection between the rotating cylinder and the upper surface of the mixing tank, the sealing performance of the equipment is effectively enhanced: preventing the material inside the mixing tank from leaking through the rotation gap, avoiding raw material waste and environmental pollution, while preventing external impurities from entering the tank and contaminating the coating, thus ensuring product quality.

[0013] Preferably, the transparent wear-resistant plate is made of quartz glass, and its edge is sealed to the inner wall of the mounting hole with sealant.

[0014] By adopting the above technical solution, the transparent wear-resistant plate is made of quartz glass and the edges are sealed with sealant, which has significant benefits: quartz glass has good light transmittance, does not affect the detection accuracy of infrared sensors, and is wear-resistant and resistant to paint corrosion, extending the service life of sensors; the sealant ensures that there is no material leakage at the mounting hole, while preventing external moisture and dust from entering and interfering with the detection.

[0015] Preferably, the inner wall of the connecting cap is provided with a bearing, and the lower end surface of the rotating rod is rotatably connected to the connecting cap through the bearing.

[0016] By adopting the above technical solution and installing bearings on the inner wall of the connecting cap, the rotation of the rotating rod and the connecting cap can be made smoother: reducing the frictional resistance when the two rotate relative to each other, reducing energy consumption, reducing component wear, ensuring stable cooperation between the rotating rod and the C-shaped rotating frame, and improving the operational stability of the equipment.

[0017] Preferably, the motor housing is made of aluminum alloy, and its inner wall is fitted with a sound insulation cotton layer; the C-shaped seat is made of ductile iron, and its interior is provided with a grease layer at the contact points with the rotating rod and the rotating cylinder.

[0018] By adopting the above technical solutions, the motor housing is made of aluminum alloy with an inner wall lined with sound-insulating cotton, and the C-type seat is made of ductile iron with a grease layer at the contact points, bringing multiple benefits: the aluminum alloy motor housing is lightweight and high-strength, facilitating equipment installation and handling; the sound-insulating cotton layer reduces motor operating noise and improves the working environment; the ductile iron C-type seat has high strength and good wear resistance, providing stable support for the rotating rod and rotating cylinder; and the grease layer reduces rotational friction, lowers energy consumption, and extends the service life of components.

[0019] In summary, this application includes at least one of the following beneficial technical effects: This high-efficiency production equipment for polyetheramine-modified epoxy resin coatings achieves bidirectional shear mixing by incorporating a rotating rod, spiral stirring blades, rotating cylinder, C-shaped rotating frame, and stirring rod, thereby improving the uniformity of coating mixing. During operation, a forward and reverse motor drives the main bevel gear to rotate. Simultaneously, the main bevel gear meshes with and drives the first and second driven bevel gears to rotate in opposite directions, causing the rotating rod and rotating cylinder to rotate in opposite directions. The rotating rod drives the spiral stirring blades to rotate clockwise, pushing the material upwards; the rotating cylinder drives the C-shaped rotating frame and stirring rod to rotate counterclockwise, creating reverse shearing on the material. The convection and shearing effects generated by bidirectional mixing effectively break up the agglomeration of high-viscosity raw materials, solving the problem of uneven mixing in traditional unidirectional mixing. This ensures that the polyetheramine-modified epoxy resin is fully integrated with other components, improving the mechanical stability of the coating. By incorporating infrared sensors, a transparent wear-resistant plate, and an external controller, real-time monitoring and dynamic control of the mixing state are achieved, reducing energy consumption and shortening the production cycle. During operation, infrared sensors perform non-contact detection of the material inside the tank through a transparent wear-resistant plate, acquiring optical data reflecting the uniformity of mixing in real time. After receiving the detection data, the external controller adjusts the output speed of the forward and reverse motors according to preset thresholds: when the material is unevenly mixed, the speed is increased to enhance shearing force; when the material reaches a uniform state, the speed is reduced to maintain stability. This dynamic adjustment mode avoids the ineffective energy consumption of traditional fixed-speed equipment and reduces production time wasted due to over-stirring, achieving efficient and low-consumption production.

A rotating cylinder 9 is connected to the lower surface of the C-shaped seat 4, and the lower end of the rotating cylinder 9 passes through the upper surface of the mixing tank 1 and is rotatably connected inside the mixing tank 1. The lower end of the rotating rod 8 passes through the second bevel gear 7 and is rotatably connected to the rotating cylinder 9 inside the mixing tank 1. A spiral stirring blade 10 is fixedly connected to the lower end surface of the rotating rod 8. C-shaped rotating frames 11 are fixedly connected to both sides of the lower end surface of the rotating cylinder 9. Stirring rods 12 are fixedly connected to the two sets of C-shaped rotating frames 11 on the side near the spiral stirring blade 10. Installation openings are provided inside the left and right sides of the mixing tank 1. An infrared sensor 14 is fixedly connected inside the mounting hole 13. A transparent wear-resistant plate 15 is fixedly connected to the side of the mounting hole 13 closest to the inside of the mixing tank 1. Both the infrared sensor 14 and the forward and reverse motors 3 are electrically connected to an external controller. The output speed of the forward and reverse motors 3 is adjusted according to the detection data of the infrared sensor 14. By setting up the forward and reverse motors 3, the main bevel gear 5, the first driven bevel gear 6, the second driven bevel gear 7, the rotating rod 8, the rotating cylinder 9, the spiral stirring blade 10, the C-shaped rotating frame 11, the stirring rod 12, the infrared sensor 14, the transparent wear-resistant plate 15, and the external controller, multiple beneficial effects are achieved: the forward and reverse motors 3 drive the rotating rod 8 and the rotating cylinder 9 to rotate in opposite directions through the bevel gear set, so that the spiral stirring blade 10 and the stirring rod 12 form a bidirectional shearing, solving the problem of uneven mixing in traditional unidirectional stirring and improving the uniformity of coating mixing; the infrared sensor 14 monitors the material status in real time through the transparent wear-resistant plate 15, and the external controller adjusts the speed of the forward and reverse motors 3 accordingly to achieve dynamic adaptation, reduce energy waste, shorten the production cycle, and meet the high-efficiency production requirements of solvent-free high-viscosity coatings.

[0024] Reference Figure 1 and Figure 2The mixing tank 1 has a feed inlet 16 fixedly connected to its upper end and a discharge outlet 17 fixedly connected to its lower end. A solenoid valve 18 is installed on the surface of the discharge outlet 17. A connecting cap 19 is rotatably connected to the lower surface of the rotating rod 8. The lower ends of two sets of C-shaped rotating frames 11 are fixedly connected to the left and right sides of the connecting cap 19. The spiral stirring blade 10 and the stirring rod 12 are made of stainless steel and their surfaces are coated with a polytetrafluoroethylene wear-resistant layer. By setting the connecting cap 19, the rotating rod 8 is connected to the two sets of C-shaped rotating frames 11, which enhances the structural stability of the stirring components: it limits the radial shaking when the rotating rod 8 and the rotating cylinder 9 rotate in opposite directions, avoids collision or abnormal gap between the spiral stirring blade 10 and the stirring rod 12 due to shaking, extends the service life of the equipment, and ensures stable stirring effect.

[0025] Reference Figure 1 , Figure 3 and Figure 4 The spiral stirring blade 10 and stirring rod 12 are made of stainless steel and coated with a polytetrafluoroethylene (PTFE) wear-resistant layer. A mechanical seal is provided at the rotating connection between the rotating cylinder 9 and the upper surface of the mixing tank 1. The use of stainless steel and a PTFE wear-resistant layer for the spiral stirring blade 10 and stirring rod 12 brings multiple advantages: the stainless steel material ensures the strength of the components and can withstand the stirring resistance of high-viscosity materials; the PTFE wear-resistant layer reduces paint adhesion, lowers cleaning difficulty, and improves the wear resistance of the components, preventing the stirring effect from being affected by wear after long-term use, and adapts to the chemical properties of the paint, preventing the material from contaminating the paint. By setting a mechanical seal at the rotating connection between the rotating cylinder 9 and the upper surface of the mixing tank 1, the sealing performance of the equipment is effectively enhanced: preventing the material in the mixing tank 1 from leaking through the rotation gap, avoiding raw material waste and environmental pollution, and preventing external impurities from entering the tank and contaminating the paint, thus ensuring product quality.

[0026] Reference Figure 1 , Figure 4 and Figure 5The transparent wear-resistant plate 15 is made of quartz glass, and its edge is sealed to the inner wall of the mounting hole 13 with sealant. The inner wall of the connecting cap 19 is equipped with a bearing, and the lower end surface of the rotating rod 8 is rotatably connected to the connecting cap 19 through the bearing. The motor housing 2 is made of aluminum alloy, and its inner wall is lined with a layer of sound-insulating cotton. The C-type seat 4 is made of ductile iron, and its internal contact parts with the rotating rod 8 and the rotating cylinder 9 are all equipped with a grease layer. The transparent wear-resistant plate 15 is made of quartz glass and its edge is sealed with sealant, which has significant advantages: quartz glass has good light transmittance, does not affect the detection accuracy of the infrared sensor 14, and is wear-resistant and resistant to paint corrosion, extending the service life of the sensor; the sealant seal ensures that there is no material leakage at the mounting hole 13, and at the same time prevents external moisture and dust from entering and interfering with the detection. By installing a bearing on the inner wall of the connecting cap 19, the rotation of the rotating rod 8 and the connecting cap 19 is made smoother: reducing the frictional resistance when the two rotate relative to each other, reducing energy consumption, and at the same time reducing component wear, ensuring the stable cooperation between the rotating rod 8 and the C-shaped rotating frame 11, and improving the operational stability of the equipment. The motor housing 2 is made of aluminum alloy and the inner wall is lined with a sound insulation cotton layer. The C-shaped seat 4 is made of ductile iron and the contact parts are provided with a grease layer, which brings many benefits: the aluminum alloy motor housing 2 is lightweight and high-strength, which facilitates equipment installation and handling; the sound insulation cotton layer reduces motor operating noise and improves the working environment; the ductile iron C-shaped seat 4 has high strength and good wear resistance, providing stable support for the rotating rod 8 and the rotating cylinder 9; the grease layer reduces rotational friction, reduces energy consumption, and extends the service life of components.

[0027] In this embodiment, bidirectional shear mixing is achieved by setting up a rotating rod 8, a spiral stirring blade 10, a rotating cylinder 9, a C-shaped rotating frame 11, and a stirring rod 12, thereby improving the uniformity of coating mixing. During operation, the forward and reverse motors 3 drive the main bevel gear 5 to rotate. The main bevel gear 5 simultaneously meshes and drives the first driven bevel gear 6 and the second driven bevel gear 7 to rotate in opposite directions, thus causing the rotating rod 8 and the rotating cylinder 9 to rotate in opposite directions: the rotating rod 8 drives the spiral stirring blade 10 to rotate clockwise, pushing the material upward; the rotating cylinder 9 drives the C-shaped rotating frame 11 and the stirring rod 12 to rotate counterclockwise, forming reverse shear on the material. The convection and shearing effects generated by bidirectional mixing can effectively break the agglomeration of high-viscosity raw materials, solve the problem of uneven mixing in traditional unidirectional mixing, ensure that the polyetheramine modified epoxy resin is fully integrated with other components, and improve the mechanical property stability of the coating; by setting up an infrared sensor 14, a transparent wear-resistant plate 15, and an external controller, the mixing state can be monitored and dynamically controlled in real time, reducing energy consumption and shortening the production cycle. During operation, the infrared sensor 14 performs non-contact detection of the material inside the tank through the transparent wear-resistant plate 15, acquiring optical data reflecting the uniformity of mixing in real time. After receiving the detection data, the external controller adjusts the output speed of the forward and reverse motors 3 according to a preset threshold: when the material is unevenly mixed, the speed is increased to enhance the shearing force; when the material reaches a uniform state, the speed is reduced to maintain stability. This dynamic adjustment mode avoids the ineffective energy consumption of traditional fixed-speed equipment, while reducing the production time wasted due to excessive stirring, achieving efficient and low-consumption production.

[0028] The implementation principle of this application embodiment is as follows: After the equipment is started, the forward and reverse motor 3 starts inside the motor housing 2, and its output end drives the main bevel gear 5 to rotate inside the C-shaped seat 4; the main bevel gear 5 simultaneously meshes with the first driven bevel gear 6 at the upper right end and the second driven bevel gear 7 at the lower end. Due to the meshing relationship, the first driven bevel gear 6 and the second driven bevel gear 7 will rotate in opposite directions; when the first driven bevel gear 6 rotates, it drives the rotating rod 8 fixedly connected inside it to rotate synchronously. The upper end of the rotating rod 8 rotates on the upper surface inside the C-shaped seat 4, and the lower end extends through the second driven bevel gear 7 and the rotating cylinder 9 into the interior of the mixing tank 1, and drives the spiral stirring blades 10 fixed on the surface to rotate; when the second driven bevel gear 7 rotates, it drives the rotating cylinder 9 fixedly connected at its lower end to rotate synchronously. The rotating cylinder 9 rotates on the lower surface of the C-shaped seat 4, and the lower end extends through the upper surface of the mixing tank 1 into the interior of the mixing tank 1, and drives the spiral stirring blades 10 fixed on the left and right sides of its lower end surface to rotate. The C-shaped rotating frame 11 rotates, causing the stirring rod 12 fixed on the C-shaped rotating frame 11 to rotate in the opposite direction to the spiral stirring blade 10. The material enters the tank from the feed port 16 at the top of the mixing tank 1 and is fully mixed under the reverse rotation of the spiral stirring blade 10 and the stirring rod 12. The connecting cap 19 is rotatably connected to the rotating rod 8 through the bearing on the inner wall, and at the same time connects the two sets of C-shaped rotating frames 11 to ensure stable operation of the stirring components. During the mixing process, the infrared sensors 14 in the mounting holes 13 on the left and right sides of the mixing tank 1 detect the mixing state of the material in the tank through the transparent wear-resistant plate 15 and transmit the data to the external controller. The external controller adjusts the output speed of the forward and reverse motors 3 according to the detection data of the infrared sensors 14 to adapt to the needs of different mixing stages of the material. After the mixing is completed, the solenoid valve 18 on the surface of the discharge port 17 at the bottom of the mixing tank 1 opens and the material is discharged. During this process, the mechanical seal at the rotating connection between the rotating cylinder 9 and the upper surface of the mixing tank 1 ensures a tight seal, the aluminum alloy material of the motor housing 2 and the inner wall sound insulation cotton layer reduce noise and weight, and the ductile iron material of the C-type seat 4 and the grease layer at the contact points ensure smooth transmission.
