Specific embodiment

[0027] The technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application, obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0028] The present application provides a technical scheme:

[0029] Please refer to Figures 1 to 6 A tin drum clothing provided with a hard particle composite coating, comprising a roller shaft body 1, the outer part of the roller shaft body 1 is wrapped with a modular tin drum clothing assembly 2, the front and rear ends of the roller shaft body 1 are fixed with connecting shafts 3, and the connecting shafts 3 are integrally formed with the roller shaft body 1.

[0030] The modular cylinder clothing assembly 2 is a circular ring composed of four groups of arc-shaped substrates 201. The bottom of the substrate 201 is fixedly provided with a matching plate 202 staggered with the substrate 201, and the top of the substrate 201 is fixedly provided with a needle tooth 205. The surface of the needle tooth 205 is covered with a hard particle nickel-based composite coating layer 207, and the surface of the hard particle nickel-based composite coating layer 207 is covered with a hard metal coating layer 206. The thickness of the hard particle nickel-based composite coating layer 207 is 0.005-0.0075 mm, and the hard particle nickel-based composite coating layer 207 contains hard particles. The thickness of the hard metal coating layer 206 is 0.002-0.0025 mm.

[0031] By adopting the above technical scheme, when the hard particle nickel-based composite coating layer 207 is made, the hard insoluble solid particles treated by the surfactant and the chromium compound are added to the conventional chemical nickel-based alloy solution in the designed special chemical container, and constant speed mechanical stirring is performed to make the hard particles uniformly disperse in the solution. According to the specification, the process control parameters are adjusted, the modular cylinder clothing assembly 2 with clean surface after strict decontamination and deoxidation is hoisted into the above-mentioned container and is rotated at a constant speed in a certain direction.

[0032] At this time, the composite plating of the modular cylinder clothing assembly 2 starts. The hard particles in the plating solution selectively adsorb metal cations in the solution, and are captured by the continuously reduced metal atoms and inlaid in the metal matrix coating layer while being reduced to metal atoms on the surface of the needle tooth 205. At the same time, under the designed stirring speed, the hard particles are very close to the surface of the workpiece, not only physical adsorption of van der Waals force occurs, but also the electrons enriched on the surface of the particles produce chemical bond adsorption with the atoms of the metal matrix on the surface of the needle tooth 205, and co-deposition with the continuously reduced metal atoms occurs, until the plating layer reaches the design thickness requirement, the workpiece is removed, and the reaction is stopped.

[0033] Subsequently, the modular cylinder clothing assembly 2 is moved into a conventional hard metal and alloy solution such as chromium, chromium alloy, tungsten or tungsten alloy for plating layer processing. In the hard particle nickel-based composite coating layer 207, due to the addition of hard particles, the plating layer has higher hardness, the hard particles bear load and block plowing, effectively prevent lattice dislocation, delay material fatigue, and improve the effective use cycle of the workpiece.

[0034] From the attached Figure 5 As can be seen, when the workpiece is dehydrated after the reaction is stopped, the hard particles adsorbed or captured on the surface are randomly mixed on the surface of the plating layer, and the flatness is poor. These surface defects will affect the product quality when the fiber is carded in the working state. After the conventional chromium, tungsten and their alloys are immediately plated on the hard particle nickel-based composite coating layer 207, a hard metal coating layer 206 is formed.Figure 6 The cross-sectional metallographic image shows that the surface of the layer is basically flat, which plays a role in filling pits and leveling peaks. This greatly improves the quality of fiber combing and extends the service life of the cylinder carding.

[0035] Specifically, such as Figure 2 As shown, one end of the substrate 201 and the bonding plate 202 are interleaved to form an overlapping groove 203, and the other end of the substrate 201 and the bonding plate 202 are interleaved to form an overlapping block 204 that matches the overlapping groove 203. The surfaces of the substrate 201 and the bonding plate 202 are provided with assembly slots 5, and the corresponding end faces of the assembly slots 5 are fixedly provided with assembly blocks 4. The assembly blocks 4 are fixed on the surfaces of the substrate 201 and the bonding plate 202, and the dimensions of the assembly slots 5 and the assembly blocks 4 are matched. The curvature of the bonding plate 202 is the same as the surface curvature of the roller body 1, and the roller body 1 and the bonding plate 202 are glued and fixed.

[0036] By adopting the above technical solution, when it is necessary to install the modular cylinder needle cloth assembly 2, the four arc-shaped base plates 201 can be assembled into a complete ring shape through the assembly block 4 and the assembly slot 5. Multiple ring-shaped modular cylinder needle cloth assemblies 2 can be quickly overlapped through the overlap groove 203 and the overlap block 204. After the front modular cylinder needle cloth assembly 2 is fitted on the outside of the roller body 1, the rear modular cylinder needle cloth assembly 2 can be installed through the overlap groove 203 and the overlap block 204, which facilitates the replacement of the modular cylinder needle cloth assembly 2.

[0037] Working principle: The bonding plate 202, substrate 201, and pin teeth 205 are made of low-alloy steel. A double-layer plating is applied to the surface of the pin teeth 205: a hard particle nickel-based composite plating layer 207 and a hard metal plating layer 206. The hard particle nickel-based composite plating layer 207 is the bottom plating layer, and the hard particles used in the hard particle nickel-based composite plating layer 207 can be diamond (1-4 micrometers), silicon carbide, or other hard material particles. The hard metal plating layer 206 is the top plating layer, composed of chromium and alloys, tungsten and alloys, etc. Through the double-layer plating process, the surface of each small pin tooth 205 is completely covered by the two plating layers, increasing the mechanical strength of each pin tooth 205. The surface hardness and wear resistance are greatly improved, effectively extending the service life and reducing material, energy and labor consumption. When the modular cylinder needle cloth assembly 2 needs to be installed, the four arc-shaped base plates 201 can be assembled into a complete ring shape through the assembly block 4 and assembly slot 5. Multiple ring-shaped modular cylinder needle cloth assemblies 2 can be quickly overlapped through the overlap groove 203 and overlap block 204. After the front modular cylinder needle cloth assembly 2 is fitted on the outside of the roller body 1, the rear modular cylinder needle cloth assembly 2 can be installed through the overlap groove 203 and overlap block 204, which facilitates the replacement of the modular cylinder needle cloth assembly 2.

[0038] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
