Description

Technical Field

[0001] This utility model relates to the technical field of wear-resistant material processing equipment, and in particular to a wear-resistant repair agent powder coating equipment. Background Technology

[0002] Wear-resistant repair agents are composite materials widely used for repairing surface wear on mechanical equipment, metal components, etc. They usually exist in powder form. In order to improve the overall performance of the repair agent powder, such as improving its flowability, enhancing its bonding strength with the matrix, or giving it specific anti-corrosion properties, it is often necessary to perform surface coating treatment on the powder particles.

[0003] In existing coating processes, a common method is wet coating, which involves placing powder in a mixing device and spraying liquid coating agent into the powder for mixing. However, at the moment the liquid coating agent comes into contact with the dry wear-resistant repair agent powder, the powder particles are rapidly attracted to each other due to the surface tension of the liquid, easily causing them to stick together and form clumps of varying sizes. Although traditional mixing equipment can agitate and stir the material, the structure of its stirring components is mainly designed for macroscopic material mixing. It lacks effective and immediate breaking and dispersing capabilities for these newly formed, highly viscous clumps during the wetting process. This results in the coating agent not being able to adhere evenly to the surface of each individual powder particle. The powder inside the clump is not effectively coated, while the powder on the outside of the clump may be over-coated, seriously affecting the quality uniformity and performance stability of the final product. At the same time, these clumps may also adhere to the inner wall of the equipment, increasing cleaning difficulty and causing material waste.

[0004] Therefore, this utility model proposes a wear-resistant repair agent powder coating device to overcome the shortcomings of the prior art. Utility Model Content

[0005] In the existing technology, when a wear-resistant repair agent powder coating equipment performs wet coating of powder, there is a common problem that the powder will quickly stick together and clump due to the addition of liquid, which affects the coating uniformity and product quality. The present invention aims to provide a wear-resistant repair agent powder coating equipment with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a wear-resistant repair agent powder coating device, including: a box, a mixing mechanism, a water pump and an atomizing nozzle; and a power component, a stirring blade and a roller rod disposed in the mixing mechanism.

[0007] The outer periphery of the roller rod is provided with a stirring column for breaking up clumps.

[0008] Furthermore, the worm gear in the power assembly meshes simultaneously with the worm wheels fixed on the stirring blade and the roller rod, respectively, thus combining the transmission method of synchronously driving the stirring and crushing components through a single power source.

[0009] Preferably, the mixing mechanism further includes a hollow elongated block that covers the outside of the meshing area between the worm and the worm wheel to provide protection.

[0010] Preferably, the device further includes a hot air blower, the air outlet of which is connected to the internal space of the housing for drying the powder.

[0011] Preferably, the top of the box is provided with a feeding pipe for conveying powder into the box.

[0012] Preferably, the device further includes a conveying mechanism located below the housing for conveying finished materials.

[0013] Preferably, the conveying mechanism includes a frame plate, a conveyor belt, a second motor, a driving wheel, and a driven wheel. The second motor drives the driving wheel and drives the driven wheel to rotate through the conveyor belt.

[0014] Preferably, the stirring blades and the roller rods are spaced apart along the axial direction of the worm gear.

[0015] Preferably, there are two roller rods, which are symmetrically arranged on both sides of the stirring blade.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that wear-resistant repair agent powder is prone to sticking and forming clumps after the coating agent is added due to moisture by setting a roller rod that can rotate synchronously when the stirring blade rotates, and using the stirring column on the outside of the roller rod to break up the agent powder. It achieves the technical effect of actively breaking up clumps while mixing and coating, ensuring that the agent powder is always in a dispersed state, thereby significantly improving the coating uniformity and product quality.

[0017] 2. This utility model solves the problems of long production cycles and easy adhesion caused by long material wetting time and low drying efficiency in traditional wet coating processes by combining a mixing mechanism with crushing and anti-adhesion function with a hot air blower. It achieves the technical effect of closely connecting the mixing, coating and drying processes, quickly solidifying the coating layer, further reducing the risk of adhesion and greatly improving production efficiency.

[0018] 3. This utility model uses a transmission method of worm gear meshing with multiple worm wheels to synchronously drive the stirring and crushing components, and integrates an automated feeding and conveying mechanism. This solves the problems of complex transmission structure or low degree of automation that may exist in existing equipment, and achieves the technical effects of compact equipment structure, stable and reliable transmission, complete automated process of the whole machine, and reduced manual intervention.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a wear-resistant repair agent powder coating equipment, which aims to solve the problem that wear-resistant repair agent powder is prone to sticking and clumping during the wet coating process in the prior art.

[0023] like Figure 1 and Figure 2As shown, the wear-resistant repair agent powder coating equipment includes a box 1 and a mixing mechanism 2 disposed inside the box 1. The box 1 serves as the working space and installation carrier for the entire equipment. The mixing mechanism 2 is used to stir, mix and crush the agent powder inside the box 1. The equipment also includes a water pump 5 and an atomizing nozzle connected to the water pump 5 and extending into the box 1. The water pump 5 and the atomizing nozzle are used to spray the coating agent onto the agent powder inside the box 1.

[0024] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the mixing mechanism 2 has a specific structure that can coordinate the stirring and mixing with the crushing and anti-sticking functions.

[0025] Please refer to the following carefully. Figure 2 and Figure 3 The structure will be described in detail below: The mixing mechanism 2 includes a power assembly 204, an agitator 202, and a roller rod 203. The power assembly 204 includes a motor 2041 fixedly mounted outside the housing 1, and a worm gear 2042 driven by the output shaft of the motor 2041. Multiple agitator columns are integrally formed or fixedly connected to the outer circumference of the roller rod 203. Worm gears 2043 are fixed to the tops of both the agitator 202 and the roller rod 203 via key connections or welding. The worm gear 2042 of the power assembly 204 is horizontally positioned above the agitator 202 and the roller rod 203, and the thread of the worm gear 2042 is connected to the worm gear 2043 of the agitator 202. The worm gears 2043 of the worm 2042 and the roller rod 203 engage simultaneously for transmission. This transmission structure, in which a single worm 2042 simultaneously engages multiple worm gears 2043, ensures that the stirring function of the stirring blade 202 and the crushing function of the roller rod 203 can be precisely synchronized. This allows for the effective dispersal of any clumps that may form as soon as the coating agent wets the powder. In addition, the mixing mechanism 2 also includes a hollow long block 201, which covers the outside of the meshing area of ​​the worm 2042 and the worm gears 2043 and is fixedly connected to the inner wall of the housing 1 by bolts. Its function is to provide protection for the transmission components.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, to rapidly dry and solidify the coated powder, the equipment also includes a hot air blower 4, please refer to... Figure 1 The air outlet of the hot air blower 4 is connected to the internal space of the housing 1. As another preferred embodiment, a feeding pipe 6 is fixedly connected to the top of the housing 1 to facilitate the addition of raw materials. As a further preferred embodiment, to achieve automated discharge, the equipment also includes a conveying mechanism 3 located below the housing 1. Please refer to... Figure 1 and Figure 4The conveying mechanism 3 includes a frame plate 301 and a second motor 302 mounted on the frame plate 301. The output shaft of the second motor 302 is fixedly connected to the driving wheel 305. The conveying mechanism 3 also includes a driven wheel 304. The conveyor belt 303 surrounds the outer periphery of the driving wheel 305 and the driven wheel 304. For a specific structural layout, please refer to [reference needed]. Figure 2 and Figure 3 The stirring blade 202 and the roller rod 203 are spaced apart along the axial direction of the worm gear 2042, and there are two roller rods 203, which are symmetrically arranged on both sides of the stirring blade 202.

[0027] Working principle: First, the wear-resistant repair agent powder is transported into the box 1 through the feeding pipe 6 at the top of the box 1. The water pump 5 is started to spray the coating agent onto the surface of the particles through the atomizing nozzle. The motor 2041 in the power assembly 204 is turned on and drives the worm 2042 to rotate synchronously. When the worm 2042 rotates, it will mesh synchronously with the stirring blade 202 and the worm wheel 2043 at the top of the roller rod 203 to achieve synchronous rotation. During the rotation of the stirring blade 202 in the mixing mechanism 2, it will stir the mixed agent powder and coating agent to enhance the coating effect. Then, during the rotation of the roller rods 203 on both sides, the multiple stirring columns on the outside will break up the clumps of powder to prevent adhesion. The hollow long block 201 can protect the worm 2042 and worm wheel 2043. During the mixing and coating process, the hot air blower 4 is started to dry and complete the coating, thereby avoiding the adhesion of the agent powder during the mixing and coating process. After the powder is mixed and coated, it is discharged through the bottom port of the box 1 onto the conveyor belt 303 of the conveying mechanism 3 below. Then, the motor 302 on the top of the frame plate 301 is started, which drives the active rotating wheel 305 to rotate. During the rotation of the active rotating wheel 305, the driven rotating wheel 304 will rotate synchronously through the outer conveyor belt 303, thereby achieving the effect of automatically feeding the coated powder.
