Description

Technical Field

[0001] This utility model relates to the field of coating mixing technology, specifically to a rapid premixing device for coatings. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. They have advantages such as being solvent-free, pollution-free, recyclable, energy-saving, and reducing labor intensity. Therefore, powder coatings are widely used in coating processes. The production and preparation of powder coatings require the pre-mixing of raw materials.

[0003] In existing technology, multiple raw materials are placed inside a mixing device and a servo motor drives a stirring rod to mix the raw materials in the mixing drum. This ensures that the produced raw materials meet the requirements for subsequent use.

[0004] However, in actual use, adding raw materials all at once results in a large volume and heavy weight of raw materials, which makes the mixing effect of the coating raw materials poor, hinders the rapid and uniform mixing of the coating raw materials, and results in poor mixing effect and low efficiency of the coating raw materials. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rapid premixing device for coatings, which solves the problem that in actual use, adding raw materials all at once results in a large volume and heavy weight of raw materials, leading to poor mixing effect and hindering the rapid and uniform mixing of coating raw materials, resulting in poor mixing effect and low efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid premixing device for coatings, comprising a base plate, a mixing chamber mounted on the top of the base plate, a cover plate mounted on the top of the mixing chamber, a connection port on the upper part of the outer wall of the mixing chamber, an installation shell on the outer wall of the connection port, the inner wall of the installation shell being rotatably connected to the upper part of the outer wall of the mixing chamber via a sealed bearing, a hopper on the inner wall of the installation shell, a feed pipe connected to the top of the hopper, and an installation frame fixedly connected to the bottom of the installation shell, the bottom of the installation frame being fixedly connected to the top of the base plate.

[0008] Preferably, a ring gear is fixedly connected to the lower part of the outer wall of the mixing chamber, a transmission gear is meshed with the outer wall of the ring gear, a servo motor is fixedly connected to one end of the mounting frame through a sealed bearing on the outer wall of the transmission gear, the outer wall of the servo motor is fixedly connected to the outer wall of the mounting frame, a fixing shell is provided on the outer wall of the ring gear, the inner wall of the fixing shell is rotatably connected to the outer wall of the mixing chamber through a sealed bearing, and the outer wall of the fixing shell is fixedly connected to the outer wall of the mounting frame.

[0009] Preferably, a limiting plate is fixedly connected to the outer wall of the cover plate, a limiting ring is fixedly connected to the bottom of the cover plate, the outer wall of the limiting ring is inserted into the inner wall of the mixing box, the inner wall of the limiting plate is sleeved on the outer wall of the feed pipe, and the outer wall of the limiting plate is fixedly connected to the top of the mounting shell by bolts.

[0010] Preferably, the bottom of the mixing tank is connected to a discharge pipe, and a valve is installed at one end of the discharge pipe.

[0011] Preferably, a collection box is provided below the discharge pipe, and the bottom of the collection box is attached to the top of the base plate.

[0012] This utility model has the following beneficial effects: The rapid premixing device for coatings, through the cooperation of the mixing box, the mounting shell, and the connection port, allows the raw materials to be placed inside the mounting shell during the mixing of the coating raw materials. The raw materials in the hopper are then introduced into the mixing box through the cooperation of the mounting shell and the connection port on the mixing box. The raw materials in the mixing box are then mixed together by the cooperation of the auger and the stirring blades. This makes mixing convenient and solves the problem of poor mixing effect of coating raw materials in the prior art, which is not conducive to the rapid and uniform mixing of coating raw materials, resulting in poor mixing effect and low efficiency of coating raw materials.

[0013] By using the combination of the limiting plate, cover plate, and feed pipe, the installation of the drive rod and stirring blades is facilitated when installing the cover plate on the mixing chamber using the limiting ring. At the same time, the limiting plates on both sides of the cover plate are fitted onto the outer wall of the feed pipe. After installation, the limiting plates are fixed to the top of the mounting shell with bolts. This ensures that the raw materials are fully mixed together when the mixing chamber rotates, solving the problem of insufficient sealing effect of the cover on the mixing chamber when mixing raw materials in the existing technology.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In actual use, adding raw materials all at once results in a large volume and heavy weight of raw materials, which makes the mixing effect of the coating raw materials poor, hinders the rapid and uniform mixing of the coating raw materials, and leads to poor mixing effect and low efficiency of the coating raw materials.

[0022] In view of this, the present invention provides a rapid premixing device for coatings, which solves the problem that when raw materials are added at once in actual use, the resulting large volume and heavy weight of raw materials lead to poor mixing effect, which is not conducive to the rapid and uniform mixing of coating raw materials, resulting in poor mixing effect and low efficiency of coating raw materials.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: By Figures 1-5It is known that a rapid premixing device for coatings includes a base plate 1, a mixing box 2 installed on the top of the base plate 1, a cover plate 16 installed on the top of the mixing box 2, a connection port 13 opened on the upper part of the outer wall of the mixing box 2, an installation shell 3 provided on the outer wall of the connection port 13, the inner wall of the installation shell 3 being rotatably connected to the upper part of the outer wall of the mixing box 2 through a sealed bearing, a material hopper 12 opened on the inner wall of the installation shell 3, a feed pipe 4 connected to the top of the material hopper 12, and an installation frame 5 fixedly connected to the bottom of the installation shell 3, the bottom of the installation frame 5 being fixedly connected to the top of the base plate 1.

[0025] In the specific implementation process, it is worth noting that the raw materials for the coating are stored in the hopper 12, and the hopper 12 and the mixing box 2 are connected together through the connection port 13. When the mixing box 2 rotates, the raw materials in the hopper 12 enter the mixing box 2, and the coating is fully mixed together during the rotation of the mixing box 2. At the same time, multiple hoppers 12 are provided, and partitions are set between the hoppers 12. When the mixing box 2 rotates, each hopper 12 is connected to the connection port 13, so that the raw materials entering the mixing box 2 each time are measured in a fixed quantity, thereby stabilizing the raw materials during mixing. At the same time, the mounting frame 5 can support the mounting shell 3 and the mixing box 2 to stabilize them during rotation. Furthermore, an auger 11 is installed on the inner wall of the mixing box 2. A drive rod 15 is fixedly connected to the top of the auger 11, and a stirring blade 14 is fixedly connected to the outer wall of the drive rod 15. The top of the drive rod 15 is fixedly connected to the bottom of the cover plate 16.

[0026] In the specific implementation process, it is worth noting that an auger 11 is installed at the bottom of the drive rod 15 so that the raw materials at the bottom of the mixing box 2 are flipped to the top of the mixing box 2. At the same time, when the raw materials enter the mixing box 2, the stirring blade 14 will mix the raw materials during the falling process. In this way, the combination of the two will make the raw materials fully mixed together.

[0027] Furthermore, a ring gear 7 is fixedly connected to the lower part of the outer wall of the mixing box 2. A transmission gear 18 is meshed with the outer wall of the ring gear 7. A servo motor 6 is fixedly connected to one end of the mounting frame 5 through a sealed bearing on the outer wall of the transmission gear 18. The outer wall of the servo motor 6 is fixedly connected to the outer wall of the mounting frame 5. A fixing shell 8 is provided on the outer wall of the ring gear 7. The inner wall of the fixing shell 8 is rotatably connected to the outer wall of the mixing box 2 through a sealed bearing. The outer wall of the fixing shell 8 is fixedly connected to the outer wall of the mounting frame 5.

[0028] In the specific implementation process, it is worth noting that the ring gear 7 is a bevel gear, and the transmission gear 18 is also a bevel gear. In this way, when the servo motor 6 drives the transmission gear 18 to rotate, it will drive the ring gear 7 to rotate synchronously. The inner wall of the ring gear 7 is fixedly connected to the outer wall of the mixing box 2. Thus, the servo motor 6 will drive the mixing box 2 to rotate, so that the raw materials inside are mixed together. The model of the servo motor 6 is not limited, as long as it meets the actual use requirements.

[0029] Example 2: From Figures 1-5 It can be seen that the outer wall of the cover plate 16 is fixedly connected to the limiting plate 20, the bottom of the cover plate 16 is fixedly connected to the limiting ring 19, the outer wall of the limiting ring 19 is inserted into the inner wall of the mixing box 2, the inner wall of the limiting plate 20 is sleeved on the outer wall of the feed pipe 4, and the outer wall of the limiting plate 20 is fixedly connected to the top of the mounting shell 3 by bolts.

[0030] In the specific implementation process, it is worth noting that by fitting the limiting plate 20 onto the outer wall of the feed pipe 4 and fixing the limiting plate 20 to the outer wall of the mounting shell 3 with bolts, the stirring blade 14 and the auger 11 at the bottom of the cover plate 16 rotate relative to the mixing box 2 when the mixing box 2 rotates, so that the raw materials in the mixing box 2 can be fully mixed.

[0031] Furthermore, the bottom of the mixing box 2 is connected to a discharge pipe 9, and a valve 10 is installed at one end of the discharge pipe 9.

[0032] In the specific implementation process, it is worth noting that the raw materials that have been mixed in the mixing box 2 are discharged by the discharge pipe 9, and the valve 10 can control the discharge of the mixing box 2 conveniently, and also ensure that the raw materials do not leak during mixing. At the same time, the model of the valve 10 is not limited, as long as it meets the actual use conditions.

[0033] Furthermore, a collection box 17 is provided below the discharge pipe 9, and the bottom of the collection box 17 is attached to the top of the base plate 1.

[0034] In the specific implementation process, it is worth noting that the mixed raw materials are collected using collection box 17, which makes it convenient for staff to carry out subsequent processing.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
