Description

Technical Field

[0001] This utility model relates to the field of waterproof coating production technology, and in particular to a feeding component for mixing waterproof coatings in production. Background Technology

[0002] Waterproof coatings are used to prevent water penetration and are widely used in construction, bridges, tunnels, water conservancy projects, and other fields. Waterproof coatings have excellent waterproofing, weather resistance, and corrosion resistance, effectively protecting buildings from moisture erosion.

[0003] Waterproof coatings can be divided into organic and inorganic waterproof coatings. Organic waterproof coatings are mainly made of organic materials such as synthetic resins and rubber, such as polyurethane waterproof coatings and acrylic waterproof coatings. Inorganic waterproof coatings are mainly made of inorganic materials such as cement and lime, such as cement-based waterproof coatings and lime-based waterproof coatings. For example, the existing technology, Chinese Patent Publication No. "CN217504954U", provides a feeding component for mixing and producing environmentally friendly waterproof coatings, which relates to the field of coating production technology. Specifically, it is a feeding component for mixing and producing environmentally friendly waterproof coatings, including a feeding frame, a support leg fixedly connected to the bottom of the feeding frame, a protective cover on the top of the feeding frame, one end of the protective cover being hinged to one side of the upper surface of the feeding frame, and a connecting block on the other end of the protective cover, with a connecting groove on the lower surface of the connecting block. This environmentally friendly waterproof coating production mixing feeding component, through the coordinated arrangement of a weighing box, a load-bearing box, a telescopic connecting pipe, a trigger plate, a mounting plate, and a control switch, can weigh the raw materials falling into the load-bearing box during use. Once the predetermined weight is reached, the feeding of raw materials stops. After the addition of raw materials is completed, the raw materials are automatically weighed again, thereby ensuring that the weight of raw materials added each time remains moderate, effectively ensuring the raw material ratio and improving product quality.

[0004] Currently, in the production of waterproof coatings, the containers used for mixing are basically only equipped with one feed inlet. If the container is large, multiple raw materials need to be fed in sequence. This not only wastes time in the feeding process, but also delays the optimal reaction and mixing time due to the excessive feeding time. Therefore, it is necessary to design a feeding component that can feed multiple materials into the container simultaneously to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a feeding assembly for mixing waterproof coatings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a feeding assembly for mixing waterproof coatings, including a feeding channel, which is a circular channel structure. A sealing plate is fixed to one end of the feeding channel. A bearing is installed through the inside of the sealing plate. The bearing is fixed to the sealing plate by welding. A feeding shaft is installed through the inside of the bearing. The surface of the feeding shaft is interference-fitted with the inner ring wall of the bearing. A spiral blade is installed inside the feeding channel and is fixedly wound around the surface of the feeding shaft. A motor is installed at the outer end of the feeding shaft. The outer wall of the motor is fixedly assembled to the surface of the sealing plate by a bracket. A drive shaft is installed inside the motor. The end of the drive shaft is fixedly connected to the end of the feeding shaft by a coupling.

[0008] The upper end of the feeding channel is fixed with a liquid feeding interface and a powder feeding interface. There are several liquid feeding interfaces and powder feeding interfaces, which are distributed at equal intervals along the longitudinal position of the feeding channel. A valve is provided on the surface of the liquid feeding interface, and the valve core of the valve is embedded inside the liquid feeding interface. A valve is provided on the surface of the powder feeding interface, and the valve core of the valve is embedded inside the powder feeding interface.

[0009] The upper flange of the liquid feeding interface is connected to a transition interface, and the upper flange of the powder feeding interface is connected to a funnel.

[0010] In detail, the feeding channel is wrapped with a support base. The inner arc surface of the support base is fixed to the outer wall of the feeding channel by screws. Two symmetrically distributed cylinders are distributed at the lower end of the support base. The cylinders are equipped with piston rods for extension and retraction. The ends of the piston rods are fixed to the surface of the support base by screws.

[0011] In detail, the same base is set at the lower end of the two cylinders. The upper end of the base is fixed to the cylinder by screws. Wheels are distributed under the base. There are at least six sets of wheels, which are evenly distributed along the bottom of the base. The base is a disc structure.

[0012] In detail, a bearing 2 is fixed to the lower end of the base, and a shaft is installed through the interior of the bearing 2. The outer wall of the shaft is interference-fitted with the inner ring wall of the bearing 2, and the lower end of the shaft is fixedly assembled with the wheel frame of the wheel by screws.

[0013] In detail, the end of the feeding channel away from the sealing plate is fitted with a feeding nozzle, and the end of the feeding channel is symmetrically distributed with limiting plates along the vertical position. One end of the limiting plate is welded to the surface of the feeding channel, and the end face of the feeding nozzle is tightly attached to the limiting plate.

[0014] In detail, a threaded post is fixed to one end of the limiting plate near the feeding nozzle, and a connecting sleeve is fixed to the outer ring wall of the feeding nozzle, with the surface of the threaded post penetrating the interior of the connecting sleeve.

[0015] In detail, the other end of the threaded column is threaded with a threaded cap, and the end face of the threaded cap is tightly fitted with the end of the connecting sleeve.

[0016] In detail, an annular groove is provided on the inner wall of the connection position between the feeding nozzle and the feeding channel. The interior of the annular groove is filled with a sealing ring. The sealing ring is set in close contact with the outer wall of the feeding channel. The sealing ring is made of water-swellable rubber material.

[0017] The design scheme proposed in this utility model has the following beneficial effects in application:

[0018] 1. When multiple liquid and powder raw materials need to be fed, liquid raw materials can be connected to the transition interface through a pipeline, and powder raw materials can be fed directly through the funnel. The two raw materials enter the feeding channel through the liquid feeding interface and the powder feeding interface respectively for centralized conveying. When the power of the motor is turned on, the motor shaft can be driven and drive the feeding shaft to rotate, so that the spiral blades can rotate synchronously. The spiral blades can feed the raw materials in a spiral manner to ensure stable feeding power. Stable feeding can be achieved by connecting the feeding nozzle to the feeding end of the mixing container.

The position of the overall structure can be adjusted by moving the wheels. The wheels can be adjusted in all directions by rotating within the bearings via the axles, thus allowing for more flexible adjustment of the feeding nozzle position. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 A feeding assembly for mixing waterproof coatings includes a feeding channel 1, which is a circular channel structure. A sealing plate 11 is fixed to one end of the feeding channel 1. A bearing 12 is installed through the inside of the sealing plate 11. The connection between the bearing 12 and the sealing plate 11 is fixed by welding. A feeding shaft 13 is installed through the inside of the bearing 12. The surface of the feeding shaft 13 is interference-fitted with the inner ring wall of the bearing 12. A spiral blade 14 is installed inside the feeding channel 1 and is fixedly wound around the surface of the feeding shaft 13. A motor 15 is installed at the outer end of the feeding shaft 13. The outer wall of the motor 15 is fixedly assembled with the surface of the sealing plate 11 by a bracket. A drive shaft is installed inside the motor 15. The end of the drive shaft is fixedly connected to the end of the feeding shaft 13 by a coupling.

[0028] The upper end of the feeding channel 1 is fixed with a liquid feeding interface 16 and a powder feeding interface 17. Several liquid feeding interfaces 16 and powder feeding interfaces 17 are provided and are distributed at equal intervals along the longitudinal position of the feeding channel 1. A valve 18 is provided on the surface of the liquid feeding interface 16, and the valve core of the valve 18 is embedded inside the liquid feeding interface 16. A valve 2 19 is provided on the surface of the powder feeding interface 17, and the valve core of the valve 2 19 is embedded inside the powder feeding interface 17.

[0029] The upper flange of the liquid feeding interface 16 is connected to a transition interface 110, and the upper flange of the powder feeding interface 17 is connected to a funnel 111.

[0030] It should be further explained that the feeding channel 1 is wrapped with a support base 2. The inner arc surface of the support base 2 is fixed to the outer wall surface of the feeding channel 1 by screws. Two symmetrically distributed cylinders 21 are distributed at the lower end of the support base 2. The cylinders 21 are equipped with piston rods for extension and retraction. The ends of the piston rods are fixed to the surface of the support base 2 by screws.

[0031] It should be further noted that the same base 22 is provided at the lower end of the two cylinders 21. The upper end of the base 22 is fixed to the cylinder 21 by screws. Wheels 23 are distributed below the base 22. There are at least six sets of wheels 23, which are evenly distributed along the bottom of the base 22. The base 22 has a disc structure. The piston rod of the cylinder 21 can extend and retract to adjust the position and height of the feed nozzle 3, so that it can be reasonably adjusted according to the height of the feed end of the container.

[0032] It should be further explained that a bearing 24 is fixed to the lower end of the base 22. A shaft 25 is installed through the inside of the bearing 24. The outer wall of the shaft 25 is interference-fitted with the inner ring wall of the bearing 24. The lower end of the shaft 25 is fixedly assembled with the wheel frame of the wheel 23 by screws. By rotating the shaft 25 relative to the bearing 24, the wheel 23 can move in all directions, thereby facilitating the flexible adjustment of the position of the feed nozzle 3.

[0033] It should be further explained that the end of the feeding channel 1 away from the sealing plate 11 is fitted with a feeding nozzle 3. The end of the feeding channel 1 is symmetrically distributed with limiting plates 31 along the vertical position. One end of the limiting plate 31 is welded to the surface of the feeding channel 1. The end face of the feeding nozzle 3 is tightly attached to the limiting plate 31. The feeding end of the feeding nozzle 3 is a non-standard part, which can be a straight structure or a curved structure. It is mainly produced according to the size of the inlet end of the container to ensure stable docking during the feeding process.

[0034] It should be further explained that a threaded post 32 is fixed at one end of the limiting plate 31 near the feeding nozzle 3, and a connecting sleeve 33 is fixed on the outer ring wall of the feeding nozzle 3. The surface of the threaded post 32 penetrates the interior of the connecting sleeve 33, which can realize the rapid positioning and docking of the feeding nozzle 3 and the feeding channel 1.

[0035] It should be further explained that the other end of the threaded column 32 is threadedly connected to a threaded cap 34. The end face of the threaded cap 34 is tightly fitted to the end of the connecting sleeve 33. When it is necessary to replace the feed nozzle 3, the threaded cap 34 is rotated to separate the threaded cap 34 from the threaded column 32, thereby separating the connecting sleeve 33 from the threaded column 32 and thus disassembling the feed nozzle 3.

[0036] It should be further explained that an annular groove 4 is provided on the inner wall of the connection position between the feeding nozzle 3 and the feeding channel 1. The interior of the annular groove 4 is filled with a sealing ring 41. The sealing ring 41 is set in close contact with the outer wall of the feeding channel 1. The sealing ring 41 is made of water-swellable rubber material. By adding a sealing ring 41 at the connection between the feeding nozzle 3 and the feeding channel 1, leakage can be avoided when liquid raw materials are transported.

[0037] Working method: When multiple liquid and powder raw materials need to be fed, the liquid raw materials can be connected to the transition interface 110 through the pipeline, and the powder raw materials can be fed directly through the funnel 111. The two raw materials enter the feeding channel 1 through the liquid feeding interface 16 and the powder feeding interface 17 respectively for centralized conveying. When the power of the motor 15 is turned on, the shaft of the motor 15 can be driven and drive the feeding shaft 13 to rotate, so that the spiral blade 14 can rotate synchronously. The spiral blade 14 can feed the raw materials in a spiral manner to ensure stable feeding power. Stable feeding can be achieved by connecting the feeding nozzle 3 to the feeding end of the mixing container.

[0038] In order to better cooperate with the feed end of the container, the height of the feeding channel 1 can be adjusted by extending and retracting the piston rod of the cylinder 21, and the height of the feeding nozzle 3 can be moved simultaneously. The position of the overall structure can be adjusted by moving the wheel 23. The wheel 23 rotates in the bearing 24 through the shaft 25, which can achieve universal adjustment, thereby allowing for more flexible adjustment of the position of the feeding nozzle 3.

[0039] When it is necessary to replace the feed nozzle 3, rotate the threaded cap 34 to separate the threaded cap 34 from the threaded post 32. This allows the threaded cap 34 to be disengaged from the threaded post 32, thereby separating the connecting sleeve 33 from the threaded post 32, and thus allowing the feed nozzle 3 to be disassembled.
