Description

Technical Field

[0001] This utility model belongs to the field of epoxy resin paint production technology, specifically relating to a raw material mixer for epoxy resin paint. Background Technology

[0002] Epoxy resin paint, as a high-performance coating, is widely used in fields such as corrosion protection, flooring, and electronic packaging. Its performance largely depends on the uniformity of the raw material mixing. Insufficient mixing can lead to incomplete curing and decreased coating performance (such as poor adhesion and insufficient chemical resistance). Therefore, efficient and uniform mixing equipment is crucial for the production of epoxy resin paint.

[0003] The mixing of epoxy resin paint mainly relies on traditional mixing equipment, such as paddle mixers. Traditional mixing mechanisms usually only use a single mixing blade. Due to the poor fluidity of high-viscosity epoxy resin, it is difficult to achieve sufficient mixing in the central area and the barrel wall area at the same time, resulting in uneven distribution of epoxy resin paint mixing raw materials and affecting production efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a raw material mixer for epoxy resin paint. This solves the problem that existing stirring mechanisms typically use only a single stirring blade, which makes it difficult to simultaneously achieve thorough mixing of the central area and the barrel wall area due to the poor fluidity of high-viscosity epoxy resin. This results in uneven distribution of epoxy resin paint mixing raw materials, affecting production efficiency.

[0005] The technical solution adopted in this utility model is as follows: a raw material mixer for epoxy resin paint, comprising a mixing device and a mixing tank;

[0006] The mixing device includes a vertical control mechanism, a mounting plate, a drive mechanism, a transmission mechanism, a first stirring mechanism, and a second stirring mechanism;

[0007] The drive end of the vertical control mechanism is connected to the mounting plate, which can drive the mounting plate to move vertically. The end of the mounting plate opposite to the vertical control mechanism extends into the top of the mixing tank.

[0008] The transmission mechanism includes a gear disk, a rotating plate, a transmission gear, and a transmission rod;

[0009] The drive mechanism is mounted on the mounting plate, the gear disk is mounted at the bottom of the mounting plate, the drive end of the drive mechanism passes through the gear disk downward and is connected to the inner end of the rotating plate and the upper end of the first stirring mechanism in sequence, which can drive the rotating plate and the first stirring mechanism to rotate. The first stirring mechanism can extend into the mixing tank. The transmission rod is rotatably connected to the rotating plate, and the upper end of the transmission rod is fixedly sleeved with the transmission gear. The transmission gear meshes with the gear disk.

[0010] The lower end of the transmission rod passes through the rotating plate and is connected to the upper end of the second stirring mechanism, and the outer end of the second stirring mechanism abuts against the inner wall of the mixing tank.

[0011] Furthermore, the vertical control mechanism is a hydraulic cylinder, which is vertically positioned on the outside of the mixing tank, with its drive end pointing upwards and fixedly connected to the bottom of the mounting plate.

[0012] Furthermore, the drive mechanism includes a motor and a drive rod;

[0013] The motor is fixedly mounted on the top of the mounting plate. The drive end of the motor passes through the mounting plate and is connected to the drive rod. The lower end of the drive rod is connected to the upper end of the first stirring mechanism. The axis of the drive rod is collinear with the axis of the mixing tank.

[0014] Furthermore, the first stirring mechanism includes a first stirring rod and double helical blades;

[0015] The lower end of the drive rod is fixedly connected to the upper end of the first stirring rod, the inner end of the rotating plate is fixedly connected to the first stirring rod, and the double helix blades are arranged on the first stirring rod.

[0016] Furthermore, the second stirring mechanism includes a second stirring rod and a single helical blade;

[0017] The lower end of the transmission rod is fixedly connected to the upper end of the second stirring rod, the single helical blade is fixedly connected to the second stirring rod, and the outer end of the single helical blade abuts against the inner wall of the mixing tank.

[0018] Furthermore, it also includes a feeding mechanism, which includes a feeding tube and a solenoid valve. Several feeding tubes are arranged in a circumferential array around the motor. Several feeding tubes are fixedly installed on the mounting plate. The lower end of the feeding tube passes through the mounting plate and the gear disk in sequence and is located above the rotating plate. Each feeding tube is equipped with a solenoid valve.

[0019] Furthermore, the bottom of the mixing tank is provided with several omnidirectional wheels arranged in a circumferential array.

[0020] The beneficial effects of this utility model are:

[0021] The drive mechanism of this utility model serves as the main drive source. The drive end of the drive mechanism drives the first stirring mechanism and the rotating plate to rotate. The first stirring mechanism forms a strong stirring in the central area of ​​the mixing tank. The rotating plate transmits part of the power to the second stirring mechanism through the meshing of the gear disk and the transmission gear. The second stirring mechanism rotates in the opposite direction to the first stirring mechanism, so that the second stirring mechanism mixes the material near the tank wall and prevents it from sticking to the wall. This differential reverse rotation generates strong shear force and convection mixing effect, ensuring uniform mixing of raw materials. Attached Figure Description

[0031] The mixing device includes a vertical control mechanism 2, a mounting plate 3, a drive mechanism 4, a transmission mechanism 5, a first stirring mechanism 6, and a second stirring mechanism 7.

[0032] The driving end of the vertical control mechanism 2 is connected to the mounting plate 3, which can drive the mounting plate 3 to move vertically. The end of the mounting plate 3 facing away from the vertical control mechanism 2 extends into the top of the mixing tank 1.

[0033] The transmission mechanism 5 includes a gear disk 51, a rotating plate 52, a transmission gear 53, and a transmission rod 54;

[0034] The drive mechanism 4 is mounted on the mounting plate 3, and the gear disk 51 is mounted at the bottom of the mounting plate 3. The drive end of the drive mechanism 4 passes downward through the gear disk 51 and is connected in sequence to the inner end of the rotating plate 52 and the upper end of the first stirring mechanism 6, which can drive the rotating plate 52 and the first stirring mechanism 6 to rotate. The first stirring mechanism 6 can extend into the mixing tank 1. The transmission rod 54 is rotatably connected to the rotating plate 52, and the upper end of the transmission rod 54 is fixedly sleeved with the transmission gear 53. The transmission gear 53 meshes with the gear disk 51. Specifically, several connecting plates are fixedly mounted on the top of the gear disk 51. The top of the connecting plates is fixedly connected to the bottom of the mounting plate 3. The inner end of the rotating plate 52 is connected to the drive end of the drive mechanism 4, and the outer end of the rotating plate 52 is rotatably connected to the transmission rod 54. The transmission gear 53 is located on the outside of the gear disk 51 and meshes with the gear disk 51.

[0035] The lower end of the transmission rod 54 passes through the rotating plate 52 and is connected to the upper end of the second stirring mechanism 7. The outer end of the second stirring mechanism 7 abuts against the inner wall of the mixing tank 1.

[0036] As a preferred embodiment, the vertical control mechanism 2 is a hydraulic cylinder 21, which is vertically positioned on the outside of the mixing tank 1. The driving end of the hydraulic cylinder 21 faces upward and is fixedly connected to the bottom of the mounting plate 3. In this embodiment, the hydraulic cylinder 21 is used as the power source, and the lifting and lowering of the mounting plate 3 is controlled by the hydraulic system, realizing precise adjustment of the height of the stirring mechanism. The stirring depth can be flexibly adjusted according to the amount of raw materials and mixing requirements, and it is easy to clean and maintain. The hydraulic system operates smoothly, has a large load-bearing capacity, and is suitable for mixing high-viscosity materials. Specifically, a mounting base is provided at the bottom of the hydraulic cylinder 21, and vertically distributed columns 22 are fixedly installed on the mounting base. The columns 22 are located behind the hydraulic cylinder 21, and the rear part of the mounting plate 3 is slidably sleeved on the columns 22, and the mounting plate 3 is vertically slidably fitted on the columns 22 for vertical guidance of the mounting plate 3.

[0037] As a preferred embodiment, the driving mechanism 4 includes a motor 41 and a driving rod 42. The motor 41 is fixedly mounted on the top of the mounting plate 3, and the driving end of the motor 41 passes through the mounting plate 3 and is connected to the driving rod 42. The lower end of the driving rod 42 is connected to the upper end of the first stirring mechanism 6, and the axis of the driving rod 42 is collinear with the axis of the mixing tank 1. In this embodiment, the motor 41 directly drives the first stirring mechanism 6 to rotate through the driving rod 42. The driving rod 42 is coaxially arranged with the mixing tank 1, ensuring the stability of central stirring and avoiding vibration and increased energy consumption caused by eccentric rotation.

[0038] As a preferred embodiment, the first stirring mechanism 6 includes a first stirring rod 61 and double helical blades 62; the lower end of the drive rod 42 is fixedly connected to the upper end of the first stirring rod 61, the inner end of the rotating plate 52 is fixedly connected to the first stirring rod 61, and the double helical blades 62 are disposed on the first stirring rod 61. The double helical blades 62 disposed on the central stirring rod create bidirectional material flow, enhancing axial mixing capacity, effectively preventing material stratification, and the double helical structure generates a strong shearing effect, which is beneficial for the dispersion and uniform distribution of the filler.

[0039] In this embodiment, a connecting rod is also included. The double helical blade 62 includes an inner helical blade and an outer helical blade. The inner and outer helical blades are mounted on the outer periphery of the first stirring rod 61 by several connecting rods. The outer helical blade is located on the outer periphery of the inner helical blade, and the helical direction of the outer helical blade is opposite to that of the inner helical blade.

[0040] As a preferred embodiment, the second stirring mechanism 7 includes a second stirring rod 71 and a single helical blade 72; the lower end of the transmission rod 54 is fixedly connected to the upper end of the second stirring rod 71, and the single helical blade 72 is fixedly connected to the second stirring rod 71, with the outer end of the single helical blade 72 abutting against the inner wall of the mixing tank 1. In this embodiment, the single helical blade 72 on the edge stirring rod remains in contact with the tank wall, achieving differential motion with the central stirring through gear transmission. The second stirring rod 71 and the single helical blade 72 mix the material near the tank wall, preventing it from sticking to the wall. Since the gear disk 51 meshes with the transmission gear 53, under the drive of the rotating plate 52, the transmission gear 53 moves circumferentially around the gear disk 51 while rotating, and drives the second stirring rod 71 to rotate, forming a speed difference with the central stirring, generating stronger shear force and convection mixing effect, resulting in better mixing of epoxy resin raw materials.

[0041] As a preferred embodiment, a feeding mechanism 8 is also included. The feeding mechanism 8 includes a feeding pipe 81 and a solenoid valve 82. Several feeding pipes 81 are arranged in a circumferential array around the motor 41. Each feeding pipe 81 is fixedly mounted on the mounting plate 3. The lower end of each feeding pipe 81 passes through the mounting plate 3 and the gear disk 51 in sequence and is located above the rotating plate 52. Each feeding pipe 81 is equipped with a solenoid valve 82. The discharge ports at the lower ends of the feeding pipes 81 all face the stirring end of the first stirring mechanism 6. In this embodiment, the rotating plate 52 is made of high-density polyethylene (HDPE). The rotating plate 52 made of HDPE has low surface energy and a dense molecular structure, making it difficult for epoxy resin raw materials to effectively wet and adhere to its surface. In addition, a vertical through groove is opened on the part of the rotating plate 52 below the feeding pipes 81 to facilitate the rapid falling of the raw materials from the outlet of the feeding pipes 81 into the mixing tank 1. Multiple feeding pipes 81 are arranged around the motor 41. The timing and flow rate of each raw material are controlled by a solenoid valve 82, achieving precise metering and relatively uniform distribution of multi-component raw materials, avoiding excessively high local concentrations. Automated control improves production efficiency and proportioning accuracy. Multiple raw materials can be poured into the mixing tank 1 through several feeding pipes 81. As the raw materials enter the mixing tank 1 and impact the stirring end of the first stirring mechanism 6, they also collide with each other, thus completing the initial mixing and accelerating the mixing rate. In this embodiment, the upper end of the feeding pipe 81 is connected to a pipe and a delivery pump for transporting various raw materials. The delivery pump uses a precision metering device such as a gear pump, plunger pump, or peristaltic pump, which is interlocked with the solenoid valve 82 to achieve quantitative feeding.

[0042] As a preferred embodiment, the bottom of the mixing tank 1 is provided with several casters 11 arranged in a circumferential array. In this embodiment, the mixing tank 1 is provided with multiple casters 11 at its bottom, forming a movable structure, which greatly improves the flexibility and site adaptability of the equipment.

[0043] The working principle of this utility model is as follows:

[0044] In use, the mixer is moved to the working position and fixed by the casters 11 at the bottom of the mixing tank 1. The hydraulic cylinder 21 is activated to drive the mounting plate 3 to rise to an appropriate height for easy material feeding. Epoxy resin, curing agent, filler, and other raw materials are added through different feeding pipes 81. The amount and order of each raw material are precisely controlled by the solenoid valve 82. The motor 41 is started, and the drive rod 42 drives the first stirring mechanism 6 to rotate. The double helical blades 62 of the first stirring mechanism 6 powerfully stir the raw materials in the central area of ​​the mixing tank 1. At the same time, the motor 41 drives the rotating plate 52 to move along with the mixing tank 1. The drive rod 42 rotates together, causing the transmission rod 54 to revolve around the gear disk 51. The transmission gear 53 meshes with the fixed gear disk 51, causing the transmission rod 54 to rotate, which in turn drives the second stirring mechanism 7 to rotate. The single spiral blade 72 of the second stirring mechanism 7 rotates along the inner wall of the mixing tank 1, thoroughly stirring the raw materials in the edge area. The first stirring mechanism 6 and the second stirring mechanism 7 work together at different speeds and directions to form a complex material flow, ensuring uniform mixing. After the predetermined mixing time is reached, the motor 41 stops running, and the hydraulic cylinder 21 lifts the mounting plate 3 to the highest position.

[0045] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
