Description

Technical Field

[0001] This utility model relates to the field of coating production equipment, specifically a homogenizing device for epoxy water-based floor coating production. Background Technology

[0002] The epoxy water-based floor paint homogenizing device is a specialized piece of equipment used in the production process of epoxy water-based floor paint to disperse, emulsify, and refine the raw materials (such as epoxy resin emulsion, pigments, fillers, additives, water, etc.). The homogenizing device breaks down agglomerated particles and unevenly dispersed components in the raw materials through mechanical or fluid dynamics, ensuring that the paint system achieves a state of uniform particle size, stable distribution, and homogeneous composition. This guarantees that the performance of the final product (such as adhesion, abrasion resistance, gloss, etc.) meets the standards. In epoxy water-based floor coating production homogenization devices, a stirring rod is typically used to mix and disperse the coating raw materials. Due to the fixed gap between the inner wall of the mixing tank and the shear blades, and the fixed rotation trajectory of the blades, the coating near the chamber wall is prone to forming a stagnant zone, which cannot be fully sheared. This results in the presence of undispersed particles or agglomerates in the coating. Some raw materials are easily adsorbed onto the inner wall of the mixing tank. At the same time, the pressure distribution inside the mixing tank is uneven, and the fluid dynamics generated by the single stirring shaft are concentrated around the shaft. The pressure difference between the upper and lower regions of the mixing chamber is too large, causing components with large density differences (such as pigments, fillers, and binders) to stratify, affecting the stability of the homogenization effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is that when existing epoxy water-based floor coating production homogenization devices are used, there is a fixed gap between the inner wall of the mixing chamber and the shear blades, which results in the presence of undispersed particles or agglomerates in the coating. Some raw materials are easily adsorbed on the inner wall of the tank, and the pressure difference between the upper and lower areas of the mixing chamber can easily cause the raw materials to separate, thus affecting the homogenization effect of the epoxy water-based floor coating.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A homogenizing device for producing epoxy water-based floor coatings includes a frame and a mixing tank. Rotating arms are fixedly connected to both ends of the mixing tank. Two limiting grooves are opened at the top of the frame for the rotating arms to rotate. A hydraulic rod is fixedly installed at the bottom of the frame. The output end of the hydraulic rod is rotatably connected to a crank arm connecting rod to drive the crank arm connecting rod to move. A connecting seat is fixedly installed on the side wall of the mixing tank for the other end of the crank arm connecting rod to rotate. Two spiral stirring rods are installed in the middle of the mixing tank. Two first motors are fixedly installed at the end of the mixing tank to drive the spiral stirring rods to rotate. A feed inlet is inserted into the top of the mixing tank. A discharge assembly is provided at the bottom of the mixing tank. The discharge assembly includes a second mounting seat installed at the bottom of the mixing tank. A solenoid valve is installed at the top of the second mounting seat to control the communication with the mixing tank.

[0005] The beneficial effects of this utility model are as follows: by starting the two first motors, the spiral stirring rods can be driven to rotate in opposite directions. The external dimensions of the spiral stirring rods are adapted to the internal dimensions of the frame, which can reduce gaps and improve the stability of raw material shearing. Then, the hydraulic rod is started, and the stirring tank is pushed to rotate and oscillate around the end of the rotating arm through the cooperation of the curved arm connecting rod and the connecting seat, thereby improving the fluidity inside the frame and thus improving the homogenization effect of epoxy water-based floor paint coating.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a vibration assembly is provided at the top of the mixing tank. The vibration assembly includes a first mounting base fixedly connected to the top of the mixing tank. Several grooves are opened in the middle of the first mounting base, and several steel balls are movably connected in the middle of each groove.

[0008] Furthermore, several protrusions are fixed to the inner bottom of the first mounting base near the slide groove to increase the collision area of ​​the steel ball, and sound insulation cotton is covered on the outer surface of the first mounting base.

[0009] Furthermore, a crash plate is movably connected to the side wall of the frame near the mixing tank, and the crash plate is used to support the side wall of the mixing tank.

[0010] Furthermore, several dampers are fixedly installed on the side walls of the anti-collision plate, and the other end of each damper is fixedly connected to the side wall of the frame. Springs are wound around the outer surface of each damper.

[0011] Furthermore, a screw conveyor is rotatably connected to the middle of the second mounting base, and a second motor is fixedly connected to the end of the second mounting base. The output end of the second motor is fixedly connected to one end of the screw conveyor.

[0012] Furthermore, a discharge pipe is inserted into the other end of the second mounting base, and the discharge pipe is connected to the second mounting base. The discharge pipe and the screw conveyor are located on the same axis.

[0013] Furthermore, a cover plate is rotatably connected to the top of the feed inlet, and a magnetic strip is snapped into the bottom of the cover plate to attract and fix the feed inlet.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: when the mixing tank vibrates, the steel balls roll and collide with the first mounting seat and the protrusion, thereby causing the mixing tank to vibrate and fall off the material adsorbed on the inner side wall of the mixing tank, thus improving the uniformity of raw material shearing and mixing; the anti-collision plate, damper and spring are used in combination to limit the displacement of the mixing tank, thereby improving the stability of the mixing tank vibration.

[0018] like Figure 1-7As shown, this utility model provides an embodiment of a homogenizing device for producing epoxy water-based floor coatings, including a frame 1 and a mixing tank 2. The frame 1 is made of cast iron for support and limiting. The mixing tank 2 is used to load the coating raw materials to be homogenized and mixed. Rotating arms 4 are fixedly connected to both ends of the mixing tank 2 by welding. Two limiting grooves 5 are opened at the top of the frame 1 for the rotating arms 4 to rotate. A bearing is installed in the middle of the limiting groove 5 to reduce the resistance of the rotating arms 4. The internal dimensions of the limiting groove 5 are adapted to the external top of the rotating arms 4 to improve the stability of the rotating arms 4. A hydraulic rod 6 is fixedly installed at the bottom of the frame 1. The output end of the hydraulic rod 6 is rotatably connected to a crank arm connecting rod 7 to drive the crank arm connecting rod 7 to move. A connecting seat 12 is fixedly installed on the side wall of the mixing tank 2 for the other end of the crank arm connecting rod 7 to rotate. Two spiral stirring rods 11 are installed in the middle of the mixing tank 2. Two first motors 8 are fixedly installed at the end of the mixing tank 2 to drive the spiral stirring rods 11 to rotate. The top of the mixing tank 2 is connected to a feed inlet 3 for operators to add epoxy water-based floor paint raw materials. The bottom of the mixing tank 2 is equipped with a discharge component 10, which includes a second mounting base 1001 installed at the bottom of the mixing tank 2. The top of the second mounting base 1001 is equipped with a solenoid valve 1002 to control the connection with the mixing tank 2. When the paint needs to be mixed, the operator first connects the external power supply and starts the two first motors 8 to drive the spiral stirring rods 11 to rotate in opposite directions. The external dimensions of the spiral stirring rods 11 are adapted to the internal dimensions of the frame 1 to reduce gaps and improve the stability of the spiral stirring rods 11 in shearing the raw materials. Then, the hydraulic rod 6 is started, which, through the cooperation of the crank arm connecting rod 7 and the connecting seat 12, pushes the mixing tank 2 to rotate and oscillate around the end of the rotating arm 4, thereby causing the paint to shake inside the mixing tank 2, thereby improving the fluidity inside the frame 1, thus avoiding paint stratification and deposition, and thus improving the homogeneity of the epoxy water-based floor paint.

[0019] In another embodiment of the mixing tank 2: a vibration assembly 9 is provided at the top of the mixing tank 2. The vibration assembly 9 includes a first mounting base 901 fixedly connected to the top of the mixing tank 2 by welding. The first mounting base 901 has several grooves 902 in the middle, and several steel balls 903 are movably connected to the middle of each groove 902. Several protrusions 904 are fixedly provided on the inner bottom of the first mounting base 901 near the grooves 902 to increase the collision area of ​​the steel balls 903. The first mounting base 901, the steel balls 903, and the protrusions 904 are all made of metal. When the mixing tank 2 vibrates... During the mixing process, the steel balls 903 roll and collide with the first mounting base 901 and the protrusion 904, thereby causing the mixing tank 2 to vibrate and fall off the material adhering to the inner wall of the mixing tank 2. This improves the uniformity of raw material shearing and mixing. The outer surface of the first mounting base 901 is covered with sound insulation cotton 905. Sound insulation cotton 905 is an acoustic material with a porous structure or fibrous structure. It is mainly made of polyester fiber, glass wool, rock wool, etc. Through its loose and porous internal structure, it absorbs sound wave energy by utilizing air resistance and fiber vibration friction, reducing sound transmission and reflection, thereby achieving sound insulation and noise reduction effects.

[0020] In another embodiment of the frame 1: a crash plate 13 is movably connected to the side wall of the frame 1 near the mixing tank 2. The crash plate 13 is used to support the side wall of the mixing tank 2. Several dampers 14 are fixedly installed on the side wall of the crash plate 13. The other end of each damper 14 is fixedly connected to the side wall of the frame 1. A spring 15 is wound around the outer surface of each damper 14. The spring 15 stores impact energy through elastic deformation. When the spring 15 is under force, it is compressed or stretched to convert kinetic energy into elastic potential energy. When unloaded, it releases energy to reduce the impact force. The damper 14 consumes energy by friction, fluid resistance, etc. When under force, it converts kinetic energy into heat energy and dissipates it through the viscosity of the damping medium such as oil or solid friction. The spring 15 and the damper 14 work together to quickly attenuate vibration and achieve buffering, thereby preventing the mixing tank 2 from colliding with the frame 1.

[0021] A screw conveyor 1005 is rotatably connected to the middle of the second mounting base 1001. A second motor 1003 is fixedly connected to the end of the second mounting base 1001. The output end of the second motor 1003 is fixedly connected to one end of the screw conveyor 1005. A discharge pipe 1004 is inserted into the other end of the second mounting base 1001. The discharge pipe 1004 is connected to the second mounting base 1001. The discharge pipe 1004 and the screw conveyor 1005 are located on the same axis. Starting the motor 1003 can drive the screw conveyor 1005 to rotate, thereby improving the stability of paint discharge.

[0022] A cover plate 16 is rotatably connected to the top of the feed inlet 3, and a magnetic strip is snapped into the bottom of the cover plate 16 to attract and fix the feed inlet 3, thereby improving the stability of the cover plate 16 in sealing.

[0023] Working principle: When using this epoxy water-based floor paint homogenizing device, the operator first connects the external power supply, then injects the paint raw material into the mixing tank 2 through the feed inlet 3, and then rotates the cover plate 16 to close the feed inlet 3. The operator starts the two first motors 8 to drive the spiral stirring rods 11 to rotate in opposite directions. The external dimensions of the spiral stirring rods 11 are adapted to the internal dimensions of the frame 1 to reduce gaps and improve the stability of the spiral stirring rods 11 in shearing the raw material. Then, the hydraulic rod 6 is started, which, through the cooperation of the crank arm connecting rod 7 and the connecting seat 12, pushes the mixing tank 2 to rotate and oscillate around the end of the rotating arm 4, thereby causing the paint to shake inside the mixing tank 2, improving the fluidity of the paint inside the frame 1, avoiding paint stratification and deposition, and thus improving the homogenization effect of the epoxy water-based floor paint.

[0024] The epoxy water-based floor coating production homogenization device improves the stability of raw material shearing through the cooperation of the mixing tank 2, the first motor 8 and the spiral mixing rod 11. Through the cooperation of the hydraulic rod 6, the curved arm connecting rod 7, the connecting seat 12, the rotating arm 4 and the frame 1, the coating inside the frame 1 can be driven to oscillate, which improves the fluidity of the coating inside the frame 1, thereby avoiding coating layering and deposition, and thus improving the homogenization effect of epoxy water-based floor coating.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
