Description

Technical Field

[0001] This invention relates to the field of waterproof coating preparation technology, and in particular to a waterproof coating mixing device with controllable feed ratio. Background Technology

[0002] Waterproof coatings are single-component water-emulsion type waterproof coatings made by adding other additives to pure acrylic polymer emulsions. After curing, the waterproof film formed by the waterproof coating has certain extensibility, elasticity, crack resistance, impermeability and weather resistance, and can play a role in waterproofing, seepage prevention and protection. Waterproof coatings have good temperature adaptability, are easy to operate and easy to repair and maintain.

[0003] The mixing device used in the production of waterproof coatings generally has a motor and a stirring plate installed inside the material tank. The material tank and the mixing device are designed as an integrated unit for rapid mixing. The mixed material is discharged through the discharge port, thereby achieving the process of mixing and stirring the raw materials of the waterproof coating.

[0004] In existing technologies, before mixing the raw materials for waterproof coatings, various raw materials need to be added in a certain proportion to prepare the waterproof coating. However, in existing technologies, the proportions of raw materials are usually prepared in advance before being added to the mixing equipment. This method is quite troublesome and consumes a lot of manual time in the early stages. Furthermore, existing waterproof coating mixing equipment does not have the capability to control the required proportions of raw materials when adding them. Therefore, the mixing time of the raw materials before mixing the waterproof coating materials will delay the overall processing efficiency. Summary of the Invention

[0011] Furthermore, the annular inner plate and the annular outer plate form ten material discharge cavities through ten partition plates. The size of each material discharge cavity is different, and the ten material discharge cavities are arranged sequentially. The annular inner plate has a material storage cavity, and the material storage cavity is connected to the ten material discharge cavities through a connecting hole provided on the annular inner plate.

[0015] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0016] Firstly, this invention employs two different types of material-carrying devices to carry different types of waterproof coating raw materials and connects them to the mixing device. The batching box carries raw materials in larger quantities, and a metering component inside the batching box measures the amount of raw materials placed there. The control mechanism carries raw materials in smaller quantities. This control mechanism uses a ten-part batching method to separately place the raw materials. Therefore, the control mechanism can deliver multiple portions of raw material A to the mixing device at a time. Then, raw material B is injected into the batching box according to the calculated proportion of raw material A, and transported to the mixing device through the batching box. This method solves the problem in existing waterproof coating mixing equipment that lacks the ability to control the required proportion of raw materials during addition, which leads to delays in overall processing efficiency due to the time required for mixing the raw materials before mixing.

[0017] Secondly, in this invention, the limiting frame is used to restrict the movable foam, so that the movable foam can only move within the limiting frame. In this way, when raw materials are injected into the mixing box, the movable foam will rise with the rise of the raw material water level. Moreover, the movable foam corresponds to the metering scale, so the movable foam will rise along the metering scale until it reaches the corresponding scale. In this way, the amount of raw materials injected can be controlled by the coordination between the movable foam and the metering scale.

[0018] Thirdly, in this invention, the sizes of the discharge cavities are set differently, so that each discharge cavity can hold different amounts of raw materials, which makes it easy to distinguish the required proportions. The counting scale on the closed plate is used to help operators distinguish the size of each discharge cavity. Attached Figure Description

Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0033] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Reference Figures 1-10 This invention provides a waterproof coating mixing device with controllable feed ratio, including a workbench 1, a mixing device 2, a batching box 3, and a material control mechanism 4. The mixing device 2 is located below the workbench 1. The batching box 3 and the material control mechanism 4 are respectively located on the two sides above the workbench 1. The upper and lower ends of the batching box 3 are respectively provided with a feed pipe 31 and a discharge pipe 32. The batching box 3 is connected to the mixing device 2 through the discharge pipe 32. The workbench 1 is provided with a feed box 11. Rectangular grooves 12 are symmetrically opened on both sides of the feed box 11. The bottom end of the feed box 11 is connected to the mixing device 2. The top end of the feed box 11 corresponds vertically to the material control mechanism 4. The batching box 3 is provided with a metering component 33.

[0035] In this invention, two different types of material carriers are used to carry different types of waterproof coating raw materials and connect them to the mixing device 2. The batching box 3 is used to carry raw materials in larger quantities, and a metering component 33 inside the batching box 3 measures the amount of raw materials placed inside. The material control mechanism 4 is used to carry raw materials in smaller quantities. The material control mechanism 4 uses a ten-part dispensing method to separately place the raw materials. In actual use, different raw materials are transported from the material control mechanism 4 and the batching box 3 to the mixing device 2 according to the adjusted ratio. For example, if the adjusted ratio of raw material A to raw material B is 1:5, one part of raw material A is transported to the mixing device 2 through the material control mechanism 4, and the metering component 33 in the batching box 3 measures the amount of raw materials placed inside. The device carries five portions of raw material B and delivers these five portions of raw material B to the mixing device 2. However, the actual amount of waterproof coating required during preparation is relatively large, so the metering ratio based on the installation ratio may be 5:25 or 7:35, etc. To increase work efficiency, the material control mechanism 4 in this invention can deliver multiple portions of raw material A to the mixing device 2 at one time. The mixing box 3 is then filled with an equal proportion of raw material B according to the amount of raw material A delivered, and delivered to the mixing device 2 through the mixing box 3. This method can solve the problem that the existing waterproof coating mixing equipment does not have the ability to control the required proportion of raw material addition, which causes the raw material mixing time to delay the overall processing efficiency before mixing the waterproof coating raw materials.

[0036] Preferably, the metering component 33 includes a limiting frame 331, a movable foam 332, and a metering scale 333. The limiting frame 331 is disposed on one side inside the mixing box 3. The movable foam 332 is movably placed inside the limiting frame 331. The metering scale 333 is engraved on the outer wall of the mixing box 3, and the position of the metering scale 333 on the mixing box 3 is made of transparent glass. The positions of the limiting frame 331 and the metering scale 333 correspond.

[0037] In this invention, the limiting frame 331 is used to restrict the movable foam 332, so that the movable foam 332 can only move within the limiting frame 331. When raw materials are injected into the mixing box 3, the movable foam 332 will rise with the rise of the raw material water level. Since the movable foam 332 corresponds to the metering scale 333, the movable foam 332 will rise along the metering scale 333 until it reaches the corresponding scale. In this way, the amount of raw materials injected can be controlled by the cooperation between the movable foam 332 and the metering scale 333.

[0038] Preferably, the material control mechanism 4 includes a support component 41, a placement component 42, and a closing component 43.

[0041] Preferably, the annular inner plate 421 and the annular outer plate 422 are formed by ten partition plates 425 to form ten material discharge cavities 4222. The space size of each material discharge cavity 4222 is different, and the space sizes of the ten material discharge cavities 4222 are arranged sequentially. The annular inner plate 421 is provided with a material storage cavity 4212. The material storage cavity 4212 is connected to the ten material discharge cavities 4222 through a connecting hole 427 provided on the annular inner plate 421. Each material discharge pipe 428 is connected to a material discharge cavity 4222 through a connecting hole 427 provided on the annular outer plate 422.

[0042] Preferably, each of the closed plates 426 corresponds to a discharge cavity 4222, each of the closed plates 426 is made of transparent material, each of the closed plates 426 is provided with a counting scale 4261, the values ​​of each of the counting scales 4261 are arranged sequentially from one to ten, and each of the closed plates 426 corresponds to a rectangular hole 4232.

[0043] In this invention, the sizes of the discharge cavities 4222 are set differently, so that each discharge cavity 4222 can hold different raw materials, which makes it easy to distinguish the required proportion. The counting scale 4261 provided on the sealing plate 426 is used to help operators distinguish the size of each discharge cavity 4222.

[0044] Preferably, one side of the feed connection pipe 424 corresponds to the material storage cavity 4212, and the other side of the feed connection pipe 424 is connected to the raw material injection device.

[0045] Preferably, the closing assembly 43 includes an annular closing plate 431, a movable connecting plate 432, a movable rod 433, a rectangular closing plate 434, a fixed connecting rod 435, and a pressing connecting plate 436. The annular closing plate 431 is rotatably disposed within the annular placement groove 4211. The movable connecting plate 432 is disposed on one side of the annular closing plate 431. The annular closing plate 431 has a communicating hole 427 that is consistent with that on the annular inner plate 421. One side of the movable rod 433 is disposed on the movable connecting plate 432, and the rod body of the movable rod 433 is located within the arc-shaped groove 4231. The other side of the movable rod 433 is located within the fixed connecting plate 436. On the outer side of the fixed outer plate 423, there are ten rectangular closing plates 434, ten fixed connecting rods 435, and ten pressing connecting plates 436. Each rectangular closing plate 434 is located in a rectangular placement groove 4221. Each rectangular closing plate 434 corresponds to a connecting hole 427 on the annular outer plate 422. One end of each fixed connecting rod 435 is connected to a rectangular closing plate 434, and the other end of each fixed connecting rod 435 extends through the fixed outer plate 423 to the outer side of the fixed outer plate 423. Each pressing connecting plate 436 is disposed on the other side of a fixed connecting rod 435.

[0046] In this invention, the feeding connection pipe 424 allows raw materials to enter the storage cavity 4212 inside the annular inner plate 421. The storage cavity 4212 stores the raw materials, which then flow into the discharge cavity 4222 through the connecting hole 427. The annular closing plate 431 opens or closes the connection between the discharge cavity 4222 and the storage cavity 4212. By moving the moving rod 433, which moves within the arc-shaped groove 4231 and drives the moving connection plate 432, the annular closing plate 431 rotates within the annular placement groove 4211. This allows the connecting hole 427 on the annular closing plate 431 to intersect with the connecting hole 427 on the annular inner plate 421, thus blocking the connection between the storage cavity 4212 and the discharge cavity 4222. The discharge cavity 4222 and the discharge pipe 428 are opened or closed by the rectangular closing plate 434. The position of the rectangular closing plate 434 is controlled by pressing or pulling out the pressing connecting plate 436. When the rectangular closing plate 434 is positioned between and corresponding to the connecting holes 427, the connection between the discharge cavity 4222 and the discharge pipe 428 is closed. When the rectangular closing plate 434 leaves the connecting hole 427 and is located in the mating groove 414, the discharge cavity 4222 and the discharge pipe 428 are connected, and the connection between the discharge cavity 4222 and the discharge pipe 428 is closed. The material flow is achieved by rotating the fixed outer plate 423 or the rotating plate 413, so that the currently used discharge cavity 4222 is located at the bottom, so that it corresponds vertically with the feed box 11. When the discharge pipe 428 rotates into the feed box 11, it will pass through the rectangular groove 12. The material located in the storage cavity 4212 will flow into the discharge pipe 428 through the connecting hole 427 under the influence of gravity. The material flows into the mixing device 2 through the discharge pipe 428 and the feed box 11.
