Description

Technical Field

[0001] The invention relates to the technical field of nail grinders, in particular to a nail grinder for pets. Background Art

[0002] Since pets come in different sizes, the nails of large and older pets are very thick, and a normal speed nail grinder cannot grind them. A nail grinder with a very high speed is required to grind the nails effectively. The nails of small pets are very tender and thin. If the speed is too high, a large section can be ground off at once, which directly causes damage to the blood line inside the nail. Once injured, the pet will be afraid and will not cooperate with nail grinding, which greatly increases the difficulty of nail grinding in the future.

[0003] Currently, nail grinders on the market have problems such as either too high a rotation speed and are only suitable for large pets, or too low a rotation speed and are only suitable for small pets. In the event of an accident such as hair getting stuck in nails, the machine cannot be stopped urgently, and there is no speed control for the rotation speed of the nail grinder, which can easily cause serious injuries. It is urgent to solve the above problems.

[0004] In addition, since pets' nails are very sharp and continue to grow during the care process, they will be easily scratched by the nails if not trimmed in time. Therefore, pets need to trim their nails regularly to keep the nails at an appropriate length that is not easily scratched. When trimming pet nails, pet-specific nail clippers need to be used. However, manual nail clippers are not easy to control the trimming length and are easy to cut the pets. Currently, nail grinders are generally used on the market to grind and trim nails. The grinding heads of existing nail grinders are all corundum sand (such as chrome corundum sand, manganese corundum sand, brown corundum sand, etc.) or quartz sand. The hardness, grinding speed and durability are far inferior to those of diamond-sprayed grinding heads, and the service life is short and the cost is high. Summary of the invention

[0005] The object of the present invention is to provide a pet nail grinder to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A pet nail grinder, comprising:

[0008] A body, wherein a grinding head is arranged at an end of the body;

[0009] Wherein, diamond sand is attached to the outside of the grinding head;

[0010] The grain size of the corundum is 40-180 meshes, the thickness of the corundum is 0.4-0.6 mm, and the uniformity of the thickness is less than or equal to 0.1 mm.

[0011] Furthermore, the step of attaching diamond grit to the outside of the grinding head is:

[0012] (1) The aluminum alloy grinding head to be sprayed is completely immersed in a degreasing agent, and the degreasing is performed at 30-40° C. for 3-4 minutes. The degreasing agent comprises the following components in parts by weight: 30-40 parts of 75wt% sulfuric acid, 2-7 parts of citric acid, 4-9 parts of ammonium bifluoride, 2-4 parts of sodium ethylenediaminetetraacetate, 0.5-1.5 parts of oxalic acid, 1-2 parts of trichloroethylene and 0.2-0.5 parts of a surfactant; wherein the surfactant is a compound of octadecyl dimethyl benzyl ammonium chloride (CAS: 122-19-0), hexadecyl trimethyl ammonium chloride (CAS: 112-02-7) and fatty alcohol polyoxyethylene ether (AEO-9) in a weight ratio of 1.3-1.6:1:0.4-0.8;

[0013] (2) The degreased aluminum alloy grinding head to be sprayed is rinsed with deionized water for 3 to 5 minutes, and then dried at 160 to 180° C. for 10 to 20 minutes to obtain a pretreated grinding head;

[0014] (3) using corundum for spraying, using pure nitrogen as plasma gas during the spraying process, with a plasma gas flow rate of 5000-5500 L / h, a plasma pressure of 4-5 MPa, an adjusted current of 750-800 A, an arc temperature of 4800-5000° C., a powder feeding amount of 0.3-0.5 g / min, and a spray gun moving speed of 40-50 mm / min; performing surface heat treatment after spraying, keeping the temperature at 400-600° C. for 15-20 h, and obtaining a grinding head after sandblasting;

[0015] (4) Use a negative ion dust removal device to remove dust from the surface of the grinding head after sandblasting.

[0016] Furthermore, diamond micropowder, nano-alumina, silicon carbide and boron nitride are added to the corundum to obtain a mixed powder for spraying. Specifically, the mixed powder includes the following components in parts by mass: 80-85 parts of corundum with a particle size D50 of 20 μm, 3-5 parts of diamond micropowder, 1-3 parts of nano-alumina, 3-6 parts of silicon carbide and 2-4 parts of boron nitride; the pretreated grinding head is sprayed with the mixed powder at 80-85°C.

[0017] The diamond powder is model W0.5 diamond powder from Zhecheng Zhongyuan Superhard Abrasives Co., Ltd.; the nano-alumina particle size is 30-60nm, and the specific surface area is 10-20m 2 / g (Zhejiang Zhiti Nano Micro New Materials Co., Ltd.), the average particle size of silicon carbide is 800nm, and the average specific surface area is 20m 2 / g (Jinlei Technology); Boron nitride particle size is 2-20μm, specific surface area is 6-25m 2 / g(Shandong Jingyi New Materials Co., Ltd.).

[0018] During the processing, storage and transportation of aluminum alloys, its surface is often contaminated with various oils and impurities such as processing oil, lubricating oil, anti-rust oil, fingerprint grease, etc., which will hinder the adhesion of corundum. In order to improve the adhesion between the surface of the aluminum alloy grinding head and the corundum, the aluminum alloy grinding head needs to be degreased. The degreasing agent used in the prior art has the problem of incomplete degreasing, which may cause defects such as bubbles, shedding, and pinholes in the frosted layer, or excessive degreasing may cause corrosion on the aluminum alloy surface, affecting subsequent processing and the durability of the product. The degreasing agent of the present invention is compounded by multiple components, and the degreasing temperature and time are reasonably controlled to obtain a good degreasing effect of the pretreated grinding head, and the adhesion with the corundum is improved. In particular, when a surfactant with a specific ratio is added to the degreasing agent, the wear resistance of the corundum on the surface of the grinding head is improved at the same time. Analysis shows that the surfactants with a specific ratio improve the surface tension of the degreaser and enhance the wetting ability of the degreaser on the surface of the aluminum alloy, allowing the degreaser to penetrate deeper into tiny gaps and depressions, effectively removing pollutants in hard-to-reach areas, and providing a more uniform and smooth foundation for the subsequent spraying of corundum, providing more anchor points for the coating, thereby enhancing the bonding strength between the coating and the substrate, and further improving the durability of the wear-resistant coating.

[0019] The inventors found that although only using corundum improves the hardness and wear resistance of the grinding head, the flatness of the corundum coating is not ideal, which affects the nail grinding effect. The present invention improves the flatness of the coating of the nail grinder by selecting corundum of a specific particle size and compounding it with other multiple components to make a mixture for spraying. Compounding components with different particle sizes has good dispersibility and grain refinement, can make the coating surface more delicate and smooth, significantly improve the flatness of the coating, and improve the integrity of the spraying. The inventors found that the corrosion resistance of the grinding head is improved under this condition. The analysis is to form a denser protective layer, thereby improving the corrosion resistance of the coating.

[0164] In some embodiments, an analysis period is set to analyze the real-time operation noise;

[0165] Obtain a real-time noise value, and compare the real-time noise value with a real-time noise threshold; wherein the real-time noise threshold is taken as: the average noise value of the main body 1a of the pet nail grinder when no foreign matter enters during operation in the historical period;

[0166] If the real-time noise value is greater than or equal to the real-time noise threshold, an abnormal operation noise signal is generated;

[0167] If the real-time noise value is less than the real-time noise threshold, a normal operation noise signal is generated;

[0168] Obtain the duration of the abnormal noise signal, and compare the duration of the abnormal noise signal with the duration threshold of the abnormal noise signal; wherein the duration threshold of the abnormal noise signal is set as follows: a critical value of the duration of the abnormal noise when the main body 1a of the pet nail grinder fails is statistically analyzed by a technician in the field in the historical time;

[0169] If the duration of the abnormal noise signal is greater than or equal to the duration threshold of the abnormal noise signal, it indicates that the abnormal noise signal has a long duration.

[0170] If the duration of the noise abnormality signal is less than the duration threshold of the noise abnormality signal, it indicates that the noise abnormality duration is short.

[0171] It should be explained that the normal / abnormal noise signal is used to evaluate whether there is foreign matter entering the main body 1a of the pet nail grinder; the long / short duration signal of the abnormal noise is used to evaluate whether the foreign matter entering affects the operation of the main body 1a of the pet nail grinder;

[0172] Similarly, set the analysis period to analyze the real-time operation noise;

[0183] If a short abnormal noise duration signal and a long abnormal temperature duration signal are obtained at the same time, or a long abnormal noise duration signal and a short abnormal temperature duration signal are obtained, it means that the noise and temperature have inconsistent duration characteristics in terms of time parameters, which affects the main body 1a of the pet nail grinder, and a driving control signal is generated;

[0184] If the noise abnormality and temperature abnormality are obtained at the same time, it means that the noise and temperature have the characteristics of long duration in terms of time parameters, which has a greater impact on the main body 1a of the pet nail grinder, and an emergency brake signal is generated;
