Description

Technical Field

[0001] This utility model relates to the field of marble production technology, specifically a marble grinding mill with anti-clogging feed. Background Technology

[0002] Marble is a common metamorphic rock, mainly formed from limestone under high temperature and pressure. Its main component is calcium carbonate, and it is usually white or light-colored. Due to impurities, it can form rich colors and textures such as red, yellow, and green. It is hard and has good processing properties, so it is widely used in architectural decoration, sculpture art and other fields. Natural marble has unique textures, and each piece is unique. It is often used as a high-end decoration material. Its surface has a high gloss after polishing, which can enhance the aesthetics and texture of the space. Marble has relatively low hardness and is easily corroded by acidic substances. In daily use, care should be taken to protect it. Overall, marble has become an important material in the fields of architecture and art due to its beauty and practicality.

[0003] Existing marble grinding mills typically have an L-shaped bend in the feed pipe during feeding. Although this feed pipe has a certain slope, the material is prone to accumulation at the bend due to the sudden change in gravity direction, causing the feeding speed to fluctuate. In addition, some fine particles are easy to adhere to the pipe wall, and long-term accumulation may cause pipe blockage. Hard impurities in marble raw materials are prone to getting stuck at the bend, which not only aggravates the wear of the inner wall of the pipe, but may also cause the marble raw material to block in the feed pipe. In view of this, we provide a marble production grinding mill with anti-blockage feed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a marble grinding mill with anti-clogging feed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a marble grinding mill with anti-clogging feed, comprising a grinding barrel, a feeding pipe fixedly connected to the top of the grinding barrel, and a horizontal feeding pipe fixedly connected to the top of the feeding pipe, a feeding component fixedly connected to one end of the top of the horizontal feeding pipe, and a first motor fixedly connected to one end of the horizontal feeding pipe, a shaft fixedly connected to the output end of the first motor, and a spiral feeding component provided at one end of the outer wall of the shaft, and a second motor fixedly connected to the center of the bottom surface of the grinding barrel, and a grinding turntable fixedly connected to the output end of the second motor.

[0006] As described above, the grinding barrel, the feeding pipe, the horizontal feeding pipe, and the inner cavity of the feeding component are interconnected, and the feeding component as a whole has a trumpet-shaped structure that is wider at the top and narrower at the bottom.

[0007] As mentioned above, the inner wall of the horizontal feeding pipe has a gradually expanding structure with one end wider than the other, and an arc-shaped connecting surface is provided at the diameter change point of the inner wall of the horizontal feeding pipe.

[0008] As described above, the spindle is rotatably connected to the center of the inner cavity of the horizontal feeding pipe, and a spiral feeding component is added to one end of the outer wall of the spindle, the spiral feeding component being located at the bottom center of the feeding component.

[0009] As described above, the spiral feeding component is spirally wound around the outer wall of one end of the shaft rod, and the outer wall of the spiral feeding component is tightly fitted to one end of the inner wall of the horizontal feeding pipe.

[0010] As described above, the grinding disc is composed of multiple hexagonal components stacked vertically, and multiple abrasive wheels are rotatably connected to the outer wall of the grinding disc. Multiple protrusions are added to the top surface of the grinding disc.

[0011] As described above, the inner wall of the grinding barrel is provided with multiple annular abrasive grooves, and the inner wall of the annular abrasive grooves rotates and fits against the outer wall of the abrasive wheel. The inner diameter of the multiple annular abrasive grooves gradually decreases from top to bottom.

[0012] Compared with existing technologies, this marble grinding mill with anti-clogging feed has the following advantages:

[0013] I. This utility model uses a first motor to drive the shaft rod and the spiral feeding component added to its outer wall to rotate. When the material enters the horizontal feeding pipe from the feeding component, the rotating spiral feeding component can push the material, enabling the material to move towards the feeding pipe at a stable speed and enter the grinding barrel, avoiding the accumulation of material at the bend. In addition, while rotating and pushing the material, the spiral feeding component can scrape off some fine particles attached to the inner wall of the horizontal feeding pipe, reducing the jamming that occurs during rotation, thereby effectively reducing the material blockage problem caused by poor feeding.

[0014] II. In this invention, after the material enters the inner wall of the grinding drum, the protrusions on the top surface of the grinding disc throw the material to the edge of the grinding drum and into the topmost annular abrasive groove, so that the material is evenly dispersed to the inner edge of the grinding drum. The top annular abrasive groove works with the rotating abrasive wheel to grind the material. Then, under the action of gravity, the material enters the lower abrasive groove with a smaller inner diameter, realizing step-by-step crushing from coarse to fine and improving the grinding quality.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0023] 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.

[0024] like Figure 1-5 As shown, this utility model provides a technical solution: a marble grinding mill with anti-clogging feeding mechanism, including a grinding barrel 1, a feeding pipe 2 fixedly connected to the top of the grinding barrel 1, and a horizontal feeding pipe 201 fixedly connected to the top of the feeding pipe 2, a feeding component 202 fixedly connected to one end of the top of the horizontal feeding pipe 201, and a first motor 203 fixedly connected to one end of the horizontal feeding pipe 201, a shaft rod 204 fixedly connected to the output end of the first motor 203, and a spiral feeding component 205 provided at one end of the outer wall of the shaft rod 204, and a second motor 102 fixedly connected to the center of the bottom surface of the grinding barrel 1, and a grinding turntable 101 fixedly connected to the output end of the second motor 102.

[0025] When the material enters the horizontal feeding pipe 201 from the feeding component 202, the spiral feeding component 205 pushes the material, allowing it to enter the grinding barrel 1 at a stable speed. It also scrapes off the fine particles attached to the inner wall of the horizontal feeding pipe 201. After the material enters the inner wall of the grinding barrel 1, the protrusions on the top surface of the grinding disc 101 throw the material to the edge of the grinding barrel 1 and it falls into the topmost annular grinding groove 104. The top annular grinding groove 104 rotates and grinds the material in conjunction with the grinding wheel 103. Then, under the action of gravity, the material enters the lower grinding groove with a smaller inner diameter, realizing a step-by-step crushing from coarse to fine and improving the grinding quality.

[0026] like Figure 3 As shown, the grinding barrel 1, the feeding pipe 2, the horizontal feeding pipe 201 and the inner cavity of the feeding component 202 are interconnected, and the feeding component 202 has a trumpet-shaped structure that is wider at the top and narrower at the bottom.

[0027] When used in conjunction with the horn-shaped feeding component 202, the material can fall through the enlarged feeding component 202, improving the feeding smoothness.

[0028] like Figure 3 As shown, the inner wall of the horizontal feeding pipe 201 has a gradually expanding structure with one end wider than the other, and an arc-shaped connecting surface 206 is provided at the diameter change point of the inner wall of the horizontal feeding pipe 201.

[0029] The gradually expanding inner wall combined with the arc-shaped connecting surface 206 can reduce the resistance during material flow, reduce the probability of large particles getting stuck, and reduce pipe wear.

[0030] like Figure 3 As shown, the spindle 204 is rotatably connected to the center of the inner cavity of the horizontal feeding pipe 201, and a spiral feeding component 205 is added to one end of the outer wall of the spindle 204. The spiral feeding component 205 is located at the bottom center of the feeding component 202.

[0031] The spiral feeding component 205 is positioned directly opposite the bottom of the feeding component 202, and can directly receive falling materials and push them.

[0032] like Figure 3 As shown, the spiral feeding component 205 is spirally wound around the outer wall of one end of the shaft rod 204, and the outer wall of the spiral feeding component 205 is tightly fitted with one end of the inner wall of the horizontal feeding pipe 201.

[0033] The close fit between the blades of the spiral feeding component 205 and the inner wall of the horizontal feeding pipe 201 can scrape off some fine particles adhering to its inner wall, avoiding long-term accumulation and scaling blockage.

[0034] like Figure 1As shown, the grinding disc 101 is composed of multiple hexagonal components stacked vertically, and multiple abrasive wheels 103 are rotatably connected to the outer wall of the grinding disc 101. Multiple protrusions are added to the top surface of the grinding disc 101.

[0035] The hexagonal stacked grinding disc 101, together with the rotating abrasive wheel 103, forms a grinding process, thereby improving grinding efficiency.

[0036] like Figure 1 As shown, the inner wall of the grinding barrel 1 is provided with multiple annular abrasive grooves 104, and the inner wall of the annular abrasive grooves 104 rotates and fits against the outer wall of the abrasive wheel 103. The inner diameter of the multiple annular abrasive grooves 104 gradually decreases from top to bottom.

[0037] The multi-layered annular abrasive grooves 104 with decreasing inner diameter form a stepped grinding structure, which allows the material to achieve a uniform particle size after being refined layer by layer.

[0038] Working Principle: In the powder production line of a marble slab processing plant, operators need to process the cut marble scraps into fine powder for use in artificial stone bonding or paint filling. Marble raw materials are manually fed into the feeding component 202. The material enters the horizontal feeding pipe 201 through the connected inner cavity. The spiral feeding component 205 on the outer wall of the shaft 204 closely adheres to the inner wall of the horizontal feeding pipe 201 and continuously pushes the material, while simultaneously scraping off fine particles adhering to the pipe wall. The horizontal feeding pipe 201... With a gradually expanding inner wall design and an arc-shaped connecting surface 206, the material falls into the grinding barrel 1 through the feeding pipe 2. The second motor 102 drives the grinding disc 101 to rotate at high speed. The protrusions added to its top surface throw the material against the barrel wall of the grinding barrel 1 and fall into the top annular grinding groove 104. The grinding disc 101 drives the grinding wheel 103 on its outer wall to rotate in contact with the inner wall of the annular grinding groove 104, crushing the material by compression. The ground powder enters the externally placed collection device through the discharge port at the bottom of the grinding barrel 1.

[0039] 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.
