Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, specifically a sand mill head for a stainless steel CNC sand mill. Background Technology

[0002] In the industrial manufacturing sector, especially in metal product processing, surface treatment, and fine chemical industries such as coatings and inks, sand milling is of paramount importance. Its main purpose is to finely grind various raw materials or semi-finished products to obtain specific particle size distribution, uniform surface quality, and ideal physicochemical properties, thereby meeting the stringent requirements of subsequent production processes or the final performance of the product. Sand mills are typically used for grinding, and they use grinding heads to grind materials in a grinding cylinder.

[0003] Chinese Utility Model Patent Publication No. CN214514964U discloses a small sand mill. This small sand mill can move the lifting column up and down by meshing a first bevel gear and a second bevel gear and meshing a transmission rotating shaft with a lifting column, thereby driving a motor to move up and down. A locking rod is provided on the side of the support column to lock the lifting column again, preventing relative movement during the operation of the sand mill from affecting the sample preparation. However, the bottom of the grinding cylinder of this small sand mill is horizontal, resulting in dead corners in the grinding process, which affects the grinding effect. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a grinding head for a stainless steel CNC sand mill, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a grinding head for a stainless steel CNC sand mill, including a base and a pad, a clamping assembly and a column located on the upper end of the base, as well as an electrical box and a motor located on the outside of the column. The output end of the motor is fixedly connected to a self-tightening head. A grinding cylinder is provided at the end of the pad away from the base, and a grinding assembly is placed inside the grinding cylinder.

[0006] The sanding assembly includes a sanding rod, sanding discs, a connecting arc surface, and a sanding strip. Multiple sanding discs are arranged on the outer side of the sanding rod, and a connecting arc surface is arranged on the outer side of the sanding rod. A sanding strip is welded to the lower end of the sanding discs near the base.

[0007] The grinding cylinder includes an outer cylinder, a water outlet pipe, a water inlet pipe, a handle, an inner cylinder, a cylinder bottom, a top cover, and a groove. The water outlet pipe is provided on the upper part of the outer cylinder, and the water inlet pipe is provided on the lower part of the outer cylinder. The inner cylinder is fixedly connected inside the outer cylinder, and the cylinder bottom is provided at the lower end of the inner cylinder.

[0008] Preferably, the grinding cylinder further includes a handle, a top cover, and a groove. The handle is fixedly connected to the outer side of the outer cylinder, and a top cover is provided at the upper end of the outer cylinder. A groove is provided at the lower end of the top cover. Two identical top covers are provided, and the groove is adapted to the upper edge of the inner cylinder.

[0009] Through the above technical solution, the matching design of the groove of the top cover and the upper edge of the inner cylinder can effectively prevent materials and grinding media from splashing out of the grinding cylinder during the grinding process, reducing material waste and pollution to the surrounding environment. The handle makes it convenient for operators to move and install the grinding cylinder, improving the ease of use of the equipment.

[0010] Preferably, a limiting piece is provided on the outer side of the grinding rod, and the grinding rod and the self-tightening head are clamped and fixedly connected.

[0011] With the above technical solution, the grinding rod and the self-tightening head are clamped and fixedly connected. When using it, first put the grinding component, the material to be ground and glass beads into the grinding cylinder, place the grinding component directly below the motor, lock and fix the grinding rod and the self-tightening head, then put the shim at the bottom of the grinding cylinder, and use the clamping assembly to press and fix the outside of the grinding cylinder. The operation process is simple and easy to assemble.

[0012] Preferably, when the sanding assembly is fixedly installed with the self-tightening rolling head, the distance between the bottom of the sanding assembly and the bottom of the cylinder is 10mm to 12mm.

[0013] With the above technical solution, the distance between the bottom of the sand grinding component and the bottom of the cylinder is set reasonably, which can ensure that the sand grinding component has enough room to move in the sand grinding cylinder for efficient sand grinding. This avoids the sand grinding component colliding with the bottom of the cylinder and damaging the equipment due to too small a distance, and also prevents the sand grinding effect from being poor due to too large a distance. It can effectively improve the uniformity and quality of sand grinding and extend the service life of the sand grinding component and the sand grinding cylinder.

[0014] Preferably, the connecting arc surface is disposed between two adjacent grinding discs, and the vertical cross-section of the grinding strip has a trapezoidal structure.

[0015] Through the above technical solutions, the connecting arc surface can make the transition between adjacent grinding discs smooth, reduce scratches and damage to the material surface during the grinding process, and improve the surface quality of the grinding; the trapezoidal structure of the grinding strip increases the contact area and friction with the material, enabling more thorough grinding of the material edges and corners.

[0016] Preferably, the bottom of the cylinder has an elliptical structure, and the diameter of the grinding disc is smaller than the inner diameter of the inner cylinder.

[0017] Through the above technical solution, the elliptical bottom of the cylinder is conducive to the better tumbling and flow of materials in the grinding cylinder as the grinding process proceeds, so that all parts of the material can be ground more evenly, improving the uniformity of grinding. The grinding component has a stirring and lifting effect, which improves the grinding efficiency.

[0018] Preferably, a cooling chamber is provided between the outer cylinder and the inner cylinder, and the water inlet pipe is connected to the external cooling water pipe.

[0019] Through the above technical solutions, the design of the cooling chamber and water inlet pipe can introduce external cooling water during the sand milling process, effectively removing the heat generated by sand milling, preventing the sand milling components and sand milling cylinder from deforming or being damaged due to overheating, extending the service life of the equipment, and also helping to stabilize the temperature environment during the sand milling process and ensure the consistency of sand milling quality.

[0020] Compared with the prior art, this utility model provides a grinding head for a stainless steel CNC sand mill, which has the following beneficial effects:

[0021] 1. The grinding head of this stainless steel CNC sand mill is used by first placing the sand milling assembly, the material to be sanded, and glass beads into the sand milling cylinder, placing the sand milling assembly directly below the motor, locking and fixing the sand milling rod to the self-tightening head, then placing the shim at the lower end of the sand milling cylinder, and using the clamp assembly to press and fix the outer side of the sand milling cylinder. The operation process is simple and easy to assemble.

[0022] 2. The grinding head of this stainless steel CNC sand mill has a reasonable distance between the bottom of the grinding assembly and the bottom of the cylinder. This ensures that the grinding assembly has sufficient space to move within the grinding cylinder for efficient grinding. It avoids damage to the equipment due to collision between the grinding assembly and the cylinder bottom caused by too small a distance, and also prevents poor grinding effect due to too large a distance. This effectively improves the uniformity and quality of grinding, and extends the service life of the grinding assembly and the grinding cylinder. The connecting arc surface design allows for a smooth transition between adjacent grinding discs, reducing scratches and damage to the material surface during grinding and improving the surface quality. The trapezoidal structure of the grinding strips increases the contact area and friction with the material, enabling more thorough grinding of the material edges and corners. The elliptical cylinder bottom facilitates better tumbling and flow of the material within the grinding cylinder during the grinding process, ensuring that all parts of the material are ground more evenly, improving grinding uniformity. The grinding assembly also has a stirring and lifting function, further enhancing grinding efficiency.

[0023] 3. The design of the grinding head, cooling chamber and water inlet pipe of this stainless steel CNC sand mill allows external cooling water to be introduced during the sand milling process, effectively removing the heat generated by the sand milling process, preventing the sand milling components and sand milling cylinder from deforming or being damaged due to overheating, extending the service life of the equipment, and also helping to stabilize the temperature environment during the sand milling process and ensure the consistency of sand milling quality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-5 As shown, the present invention provides a grinding head for a stainless steel CNC sander, including a base 1 and a pad 2, a clamping assembly 3 and a column 4 located on the upper end of the base 1, as well as an electrical box 5 and a motor 6 located on the outside of the column 4. The output end of the motor 6 is fixedly connected to a self-tightening head 7. A sanding cylinder 9 is provided at the end of the pad 2 away from the base 1, and a sanding assembly 8 is placed inside the sanding cylinder 9.

[0032] The sanding assembly 8 includes a sanding rod 801, a sanding disc 802, a connecting arc surface 803, and a sanding strip 804. Multiple sanding discs 802 are provided on the outer side of the sanding rod 801, and a connecting arc surface 803 is provided on the outer side of the sanding rod 801. A sanding strip 804 is welded to the lower end of the sanding disc 802 near the base 1.

[0033] The sanding cylinder 9 includes an outer cylinder 901, a water outlet pipe 902, a water inlet pipe 903, a handle 904, an inner cylinder 905, a cylinder bottom 906, a top cover 907, and a groove 908. The water outlet pipe 902 is provided on the upper part of the outer side of the outer cylinder 901, and the water inlet pipe 903 is provided on the lower part of the outer side of the outer cylinder 901. The inner cylinder 905 is fixedly connected inside the outer cylinder 901, and the cylinder bottom 906 is provided at the lower end of the inner cylinder 905.

[0034] Specifically, the grinding cylinder 9 also includes a handle 904, a top cover 907, and a groove 908. The handle 904 is fixedly connected to the outer side of the outer cylinder 901. The top cover 907 is provided at the upper end of the outer cylinder 901, and the groove 908 is provided at the lower end of the top cover 907. There are two identical top covers 907, and the groove 908 is adapted to the upper edge of the inner cylinder 905. The advantage is that the adaptation design of the groove 908 of the top cover 907 to the upper edge of the inner cylinder 905 can effectively prevent materials and grinding media from splashing out of the grinding cylinder 9 during the grinding process, reducing material waste and pollution to the surrounding environment. The handle 904 makes it convenient for operators to move and install the grinding cylinder 9, improving the ease of use of the equipment.

[0035] Specifically, a limiting piece is provided on the outer side of the grinding rod 801, and the grinding rod 801 is clamped and fixedly connected to the self-tightening head 7. The advantage is that the grinding rod 801 and the self-tightening head 7 are clamped and fixedly connected. When using it, first put the grinding assembly 8, the material to be ground, and glass beads into the grinding cylinder 9, place the grinding assembly 8 directly below the motor 6, lock and fix the grinding rod 801 and the self-tightening head 7, then put the shim 2 on the lower end of the grinding cylinder 9, and use the clamp assembly 3 to press and fix the outer side of the grinding cylinder 9. The operation process is simple and easy to assemble.

[0036] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0037] Specifically, when the sand mill assembly 8 and the self-tightening roller head 7 are fixedly installed, the distance between the bottom of the sand mill assembly 8 and the bottom of the cylinder 906 is 10mm to 12mm. The advantage is that this reasonable distance ensures that the sand mill assembly 8 has sufficient space to move within the sand mill cylinder 9 for efficient sand milling. It avoids damage to the equipment due to collisions between the sand mill assembly 8 and the bottom of the cylinder 906 caused by an excessively small distance, while also preventing poor sand milling results due to an excessively large distance. This effectively improves the uniformity and quality of sand milling and extends the service life of both the sand mill assembly 8 and the sand mill cylinder 9.

[0038] Specifically, the connecting arc surface 803 is positioned between two adjacent grinding discs 802, and the grinding strip 804 has a trapezoidal vertical cross-section. The advantages are that the connecting arc surface 803 allows for a smooth transition between adjacent grinding discs 802, reducing scratches and damage to the material surface during grinding and improving surface quality; the trapezoidal structure of the grinding strip 804 increases the contact area and friction with the material, enabling more thorough grinding of material edges and corners.

[0039] Specifically, the bottom 906 of the cylinder has an elliptical structure, and the diameter of the grinding disc 802 is smaller than the inner diameter of the inner cylinder 905. The advantage is that the elliptical bottom 906 facilitates better tumbling and flow of the material within the grinding cylinder 9 during the grinding process, allowing all parts of the material to be ground more evenly, thus improving grinding uniformity. The grinding assembly 8 also has a stirring and lifting function, enhancing grinding efficiency.

[0040] Specifically, a cooling chamber is provided between the outer cylinder 901 and the inner cylinder 905, and the water inlet pipe 903 is connected to the external cooling water pipe. The advantage is that the design of the cooling chamber and the water inlet pipe 903 allows external cooling water to be introduced during the sand milling process, effectively removing the heat generated during sand milling, preventing the sand milling assembly 8 and the sand milling cylinder 9 from deforming or being damaged due to overheating, extending the service life of the equipment, and also helping to stabilize the temperature environment during the sand milling process, ensuring the consistency of sand milling quality.

[0041] Working Principle: In use, first place the grinding assembly 8, the material to be ground, and glass beads into the grinding cylinder 9. Position the grinding assembly 8 directly below the motor 6. Lock and secure the grinding rod 801 to the self-tightening head 7. Then, place the shim 2 at the bottom of the grinding cylinder 9 and use the clamp assembly 3 to press and secure the outer side of the grinding cylinder 9. During grinding, maintain an appropriate distance between the bottom of the grinding assembly 8 and the cylinder bottom 906. This ensures sufficient space for efficient grinding within the grinding cylinder 9, preventing damage from collisions caused by insufficient spacing. The connecting arc surface 803 allows for a smooth transition between adjacent grinding discs 802, reducing scratches and damage to the material surface during grinding and improving the grinding surface finish. The trapezoidal structure of the grinding strips 804 increases the contact area and friction with the material. The elliptical bottom 906 facilitates better tumbling and flow of the material within the grinding cylinder 9 during the grinding process, ensuring more uniform grinding of all parts of the material and improving grinding uniformity. The grinding assembly 8 has a stirring and lifting function, improving grinding efficiency. When long-term grinding operations are required, external cooling water can be introduced during the grinding process. The cooling water is injected through the inlet pipe 903 and discharged through the outlet pipe 902, effectively removing the heat generated by grinding and preventing the grinding assembly 8 and grinding cylinder 9 from deforming or being damaged due to overheating, thus extending the service life of the equipment. It also helps stabilize the temperature environment during the grinding process, ensuring the consistency of grinding quality.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
