Description

Technical Field

[0001] This utility model relates to the field of mineral coating powder mixing technology, and in particular to a mineral coating powder mixing device. Background Technology

[0002] With the promotion of green building concepts, mineral coatings, due to their excellent properties such as environmental protection, weather resistance, and fire resistance, are increasingly widely used in building decoration, industrial protection, and other fields. The core performance of mineral coatings (such as adhesion, corrosion resistance, and color uniformity) largely depends on the mixing quality of their powder raw materials. If the mixing is uneven, it can easily lead to problems such as color difference, cracking, and peeling of the coating.

[0003] In existing technologies, due to the special physical properties of mineral coating powders, some of which have extremely fine particle sizes and high surface energy, they are prone to agglomeration during transportation. These agglomerated powder particles gradually accumulate in the pores of the filter structure, eventually causing severe blockage of the filter channels. This blockage not only significantly reduces the material transportation efficiency but also causes a sharp drop in the feeding rate of the entire production system. More seriously, in order to maintain normal production, operators have to frequently interrupt the production process to manually clean and maintain the filter structure, which not only increases labor costs but also seriously affects the continuity and production efficiency of the production line. Utility Model Content

[0004] The purpose of this invention is to solve the problems of easy clogging of filter holes and excessive powder residue on the inner wall of the mixing chamber in the existing technology, and to propose a mineral coating powder mixing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mineral coating powder mixing device, comprising a mixing chamber, a support frame and a feeding hopper.

[0006] A support frame is fixedly connected to the outer surface of the mixing chamber. The feed hopper is fixedly connected to the top of the mixing chamber. A servo motor is fixedly connected to the bottom of the mixing chamber. A rotating rod is fixedly connected to the output end of the servo motor. The bottom end of the rotating rod is rotatably connected to the bottom of the mounting rod. The mounting rod is fixedly connected to the inner wall of the mixing chamber. A stirring rod is fixedly connected to the bottom end of the outer surface of the rotating rod. A cleaning brush is fixedly connected to the top end of the outer surface of the rotating rod. A connecting groove is provided on the inner wall of the mixing chamber. A filter plate is slidably engaged inside the connecting groove. A vibration mechanism is provided on the outer surface of the mixing chamber.

[0007] The vibration mechanism includes a drive structure fixedly connected to the outer surface of the mixing chamber, and a vibration rod fixedly connected to the output end of the drive structure, the vibration rod being located below the filter plate.

[0008] Furthermore, the drive structure includes a mounting plate fixedly connected to the outer surface of the mixing chamber, a geared motor fixedly mounted on the outer surface of the mounting plate, a belt drive assembly fixedly connected to the output end of the outer surface of the geared motor, and the output end of the belt drive assembly fixedly connected to the vibrating rod.

[0009] Furthermore, the end of the vibrating rod away from the reduction motor is rotatably connected to the inner wall of the mixing chamber, and a contact block is fixedly connected to the outer surface of the vibrating rod.

[0010] Furthermore, the touch block is teardrop-shaped and located directly below the filter plate.

[0011] Furthermore, the cleaning brush includes a connecting ring fixedly connected to the outer surface of the rotating rod, and an L-shaped rod is fixedly connected to the outer surface of the connecting ring.

[0012] Furthermore, the L-shaped rods are distributed circumferentially on the outer surface of the connecting ring, and a brush is fixedly connected to the side surface of the L-shaped rods near the inner wall of the mixing chamber.

[0013] Furthermore, the support frame includes a fixing ring fixedly connected to the outer surface of the mixing chamber, and a support foot is fixedly connected to the outer surface of the fixing ring.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, by setting up a vibration mechanism, the reduction motor drives the vibrating rod to rotate at a uniform speed through the belt drive assembly. The teardrop-shaped contact blocks on the vibrating rod circulate and contact the bottom of the filter plate, generating slight vibration. This design can effectively prevent mineral coating powder from agglomerating and clogging in the filter holes of the filter plate, ensuring the feeding efficiency of the feed hopper into the mixing chamber, and solving the problem of easy clogging of the filter structure in the prior art, which requires frequent shutdowns for cleaning.

[0016] 2. In this invention, by setting a cleaning brush, when the servo motor drives the rotating rod to rotate, the connecting ring synchronously drives the circumferentially distributed L-shaped rods to rotate, and the brushes on the L-shaped rods slide closely against the inner wall of the mixing chamber. This structure can clean the residual mineral coating powder on the inner wall of the mixing chamber in real time, which not only avoids the waste of raw materials, but also prevents the mixing contamination caused by the residue of different batches of powder on the chamber wall, solving the problem of difficult cleaning of powder on the inner wall of the mixing chamber in the prior art.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a mineral coating powder mixing device, including a mixing chamber 1, a support frame 2 and a feeding hopper 3.

[0025] A support frame 2 is fixedly connected to the outer surface of the mixing chamber 1. A feed hopper 3 is fixedly connected to the top of the mixing chamber 1. A servo motor 4 is fixedly connected to the bottom of the mixing chamber 1. A rotating rod 41 is fixedly connected to the output end of the servo motor 4. The bottom end of the rotating rod 41 is rotatably connected to the bottom of the mounting rod 11. The mounting rod 11 is fixedly connected to the inner wall of the mixing chamber 1. A stirring rod 42 is fixedly connected to the bottom end of the outer surface of the rotating rod 41. A cleaning brush 5 is fixedly connected to the top end of the outer surface of the rotating rod 41. A connecting groove 12 is provided on the inner wall of the mixing chamber 1. A filter plate 6 is slidably engaged inside the connecting groove 12. A vibration mechanism 7 is provided on the outer surface of the mixing chamber 1.

[0026] The following section will explain the specific setup and function of the filter plate 6 and the vibration mechanism 7.

[0027] In this embodiment: the vibration mechanism 7 includes a drive structure 71 fixedly connected to the outer surface of the mixing chamber 1, and a vibration rod 72 fixedly connected to the output end of the drive structure 71. The vibration rod 72 is located below the filter plate 6.

[0028] The effect achieved by the above components is as follows: the driving structure 71 provides power to the vibrating rod 72, so that the vibrating rod 72 can apply periodic force to the filter plate 6, avoid the mineral coating powder from agglomerating and clogging in the filter holes of the filter plate 6, ensure that the feed hopper 3 continuously and stably feeds into the mixing chamber 1, and eliminates the need for frequent shutdowns to clean the filter plate 6, thereby improving the overall operating efficiency of the device.

[0029] Specifically, the drive structure 71 includes a mounting plate 711 fixedly connected to the outer surface of the mixing chamber 1. A geared motor 712 is fixedly mounted on the outer surface of the mounting plate 711. A belt drive assembly 713 is fixedly connected to the output end of the outer surface of the geared motor 712. The output end of the belt drive assembly 713 is fixedly connected to the vibrating rod 72.

[0030] The effects achieved by the above components are as follows: the mounting plate 711 provides a stable mounting base for the geared motor 712, preventing the geared motor 712 from shifting due to vibration during operation; the geared motor 712 has an adjustable output speed, ensuring that the vibrating rod 72 rotates at a suitable frequency, preventing excessive vibration damage to the filter plate 6 due to excessive speed, or failure to achieve the anti-clogging effect due to excessive speed; the belt drive assembly 713 can smoothly transmit the power of the geared motor 712, while also having a certain buffering effect, reducing the impact on the vibrating rod 72 and the geared motor 712 during power transmission, and extending the service life of the components.

[0031] Specifically, the end of the vibrating rod 72 away from the reduction motor 712 is rotatably connected to the inner wall of the mixing chamber 1, and a contact block 721 is fixedly connected to the outer surface of the vibrating rod 72.

[0032] The effect achieved by the above components is as follows: the two ends of the vibrating rod 72 are connected to the inner wall of the mixing chamber 1 and the belt drive assembly 713 respectively, forming a stable rotational support structure, which prevents the vibrating rod 72 from shaking or deviating when rotating, and ensures that the contact block 721 can act accurately on the filter plate 6; as a component that directly contacts the filter plate 6, the contact block 721 can convert the rotational motion of the vibrating rod 72 into a periodic contact force on the filter plate 6, causing the filter plate 6 to vibrate slightly and shake off the powder that is blocked in the filter holes.

[0033] Specifically, the touch block 721 is teardrop-shaped and is located directly below the filter plate 6.

[0034] The effects achieved by the above components are as follows: when the teardrop-shaped contact block 721 contacts the filter plate 6, its arc-shaped surface can reduce the contact area and impact force with the filter plate 6, avoid mechanical damage to the filter plate 6, and at the same time ensure sufficient vibration force; the contact block 721 is located directly below the filter plate 6, which can ensure that the vibration is directly transmitted to the filtration area of ​​the filter plate 6, covering the main feeding range of the filter plate 6, and improving the comprehensiveness of the anti-clogging effect.

[0035] Specifically, the cleaning brush 5 includes a connecting ring 51 fixedly connected to the outer surface of the rotating rod 41, and an L-shaped rod 52 fixedly connected to the outer surface of the connecting ring 51.

[0036] The effects achieved by the above components are as follows: the connecting ring 51 can stably fix the L-shaped rod 52 on the rotating rod 41, ensuring that the L-shaped rod 52 can move synchronously when the rotating rod 41 rotates; the structural design of the L-shaped rod 52 can extend the effective radius of the cleaning brush 5, so that it can cover different height areas of the inner wall of the mixing chamber 1, avoiding local powder residue on the chamber wall due to insufficient cleaning range.

[0037] Specifically, the L-shaped rods 52 are distributed in a circumferential interval on the outer surface of the connecting ring 51, and a brush 53 is fixedly connected to the side surface of the L-shaped rods 52 near the inner wall of the mixing chamber 1.

[0038] The effects achieved by the above components are as follows: the circumferentially spaced L-shaped rods 52 allow the brushes 53 to evenly cover the inner circumferential surface of the mixing chamber 1, avoiding cleaning dead corners; the brushes 53 are soft and have a certain degree of elasticity, allowing them to slide closely against the inner wall of the mixing chamber 1, cleaning residual powder without scratching the inner wall of the mixing chamber 1, reducing raw material waste and preventing cross-contamination of different batches of mineral coating powder due to residue on the chamber wall, thus ensuring the purity of the mixture.

[0039] Specifically, the support frame 2 includes a fixing ring 21 fixedly connected to the outer surface of the mixing chamber 1, and a support foot 22 fixedly connected to the outer surface of the fixing ring 21.

[0040] The effects achieved by the above components are as follows: the fixing ring 21 can increase the contact area between the support frame 2 and the mixing chamber 1, so that the weight of the mixing chamber 1 can be evenly transferred to the support frame 2, avoiding excessive local stress on the mixing chamber 1 and deformation; the support feet 22 are evenly distributed on the outside of the fixing ring 21, which can provide stable support for the entire device, preventing the device from tilting or shifting during mixing operations, especially when the servo motor 4 and the vibrating mechanism 7 are running simultaneously and vibrating, thus improving the safety and stability of the device operation.

[0041] Working principle: When using this mineral coating powder mixing device, the mineral coating powder to be mixed is first poured into the feed hopper 3. The powder is first filtered through the filter plate 6 to remove impurities or large particles. At the same time, the reduction motor 712 of the vibration mechanism 7 is started. The reduction motor 712 drives the vibrating rod 72 to rotate at a constant speed through the belt drive assembly 713. The water droplet-shaped contact block 721 on the vibrating rod 72 circulates to touch the bottom of the filter plate 6, causing the filter plate 6 to vibrate slightly, avoiding powder clogging the filter holes and ensuring that the powder enters the mixing chamber 1 smoothly.

[0042] Then, the servo motor 4 at the bottom of the mixing chamber 1 is started. The servo motor 4 drives the rotating rod 41 to rotate. The stirring rod 42 at the bottom of the rotating rod 41 rotates synchronously to stir and mix the powder in the mixing chamber 1. At the same time, the cleaning brush 5 at the top of the rotating rod 41 rotates with the rotating rod 41. The connecting ring 51 drives the L-shaped rods 52 distributed in a circle to move. The brushes 53 on the L-shaped rods 52 slide against the inner wall of the mixing chamber 1 to clean the powder remaining on the chamber wall in real time.

[0043] Throughout the mixing process, the mounting rod 11 provides auxiliary support to the rotating rod 41, reducing the shaking of the stirring rod 42 during rotation, avoiding dead zones in the mixing, and improving the uniformity of the mixture. The fixing ring 21 and support feet 22 of the support frame 2 provide stable support for the device and prevent displacement. After mixing is completed, the servo motor 4 and the reduction motor 712 are turned off, and the discharge structure at the bottom of the outer surface of the mixing chamber 1 (not shown in the diagram) is opened to discharge the uniformly mixed mineral coating powder.
