Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a long-life corrosion-resistant grinding tool. Background Technology

[0002] A grinder is a tool or device specifically designed for crushing and grinding materials. It uses specific grinding media (such as abrasive particles, grinding discs, grinding rods, etc.) to apply pressure to the material and create relative motion. Through friction and grinding, the material is crushed and ground to the desired particle size, shape, or surface properties. This device is widely used in many fields, including household use, chemical, pharmaceutical, food processing, and metallurgy, to meet the material handling needs of different scenarios.

[0003] Existing grinders are usually only suitable for specific types of materials or grinding needs, and the flexibility of adjusting the grinding gap is limited. When different types or different particle sizes of materials need to be processed, the entire grinder needs to be replaced or complex adjustments need to be made, which increases the difficulty of operation and cost. Utility Model Content

[0004] The purpose of this invention is to provide a long-life, corrosion-resistant grinder. This device improves the flexibility of grinder use, thus solving the problem of poor flexibility in the use of existing grinders.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A long-life, corrosion-resistant grinder includes a housing with a grinding disc slidably connected inside; a top cover located at the top of the housing, with a column rotatably connected to the lower end of the top cover and a protrusion fixedly connected to the lower end of the column; and a vertical rod located inside the housing, with a groove at its upper end slidably connected to the protrusion, and a grinding head fixedly connected to the lower end of the vertical rod, the lower end of which fits against the inner wall of the grinding disc.

[0007] Preferably, a movable shell is threadedly connected to the side wall of the housing, and a movable ring is slidably connected to the side wall of the housing, the movable ring being rotatably connected to the interior of the movable shell.

[0008] Preferably, a sliding groove is provided through both sides of the housing, and a connecting rod is slidably connected inside the sliding groove. One end of the connecting rod is fixedly connected to the side wall of the grinding disc, and the other end of the connecting rod is fixedly connected to the inner wall of the movable ring.

[0009] Preferably, the upper end of the housing is provided with a groove, and the upper cover is threadedly connected to the groove.

[0010] Preferably, a motor is fixedly connected inside the upper cover, and the output end of the motor is fixedly connected to the upper end of the column.

[0011] Preferably, a ring plate is rotatably connected to the side wall of the vertical rod, and multiple horizontal bars are fixedly connected to the side wall of the ring plate. The multiple horizontal bars are distributed in a circular array, and the ends of the horizontal bars are fixedly connected to the inner wall of the housing.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. By manually rotating the movable shell, the movable shell causes the movable ring to slide downwards. The movable ring, through the connecting rod, causes the grinding disc to slide downwards, adjusting the gap between the inner wall of the grinding disc and the lower end of the grinding head. This controls the particle size of the ground material, allowing the device to adapt to different grinding needs and improving its flexibility and practicality.

[0014] 2. When cleaning the inside of the housing is required, manually rotate the top cover to unscrew it from the inside of the slot, thus removing the top cover from the top of the housing. At the same time, the protrusion slides out from the groove. Then, remove the bolts between the crossbar and the housing, and remove the vertical bar from the inside of the housing. This allows for individual cleaning of the grinding disc, the lower end of the top cover, and the surface of the vertical bar (i.e., the lower grinding head). Disassembling the top cover, vertical bar, and other components allows for a more thorough cleaning of the inside of the housing, including the grinding disc, the lower end of the top cover, the surface of the vertical bar, and the grinding head at its lower end. This helps remove residues and debris generated during the grinding process, keeping the equipment clean and hygienic, and avoiding adverse effects on subsequent grinding processes.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A long-life, corrosion-resistant grinding tool includes a housing 001, with a grinding disc 101 slidably connected inside the housing 001; a top cover 002, located on the upper end of the housing 001, with a column 202 rotatably connected to the lower end of the top cover 002, and a protrusion 203 fixedly connected to the lower end of the column 202; and a vertical rod 003, located inside the housing 001, with a groove 303 at its upper end, the groove 303 slidably connected to the protrusion 203, and a fixed connection at the lower end of the vertical rod 003. The grinding head 304 has its lower end fitted against the inner wall of the grinding disc 101. Both the grinding head 304 and the grinding disc 101 are made of ceramic. The protrusions 203 and grooves 303 are both hexagonal rhomboids. The fit between the inner wall of the grinding disc 101 and the lower end of the grinding head 304 changes from wide to narrow. The lower end of the grinding head 304 fits against the inner wall of the grinding disc 101, sealing the interior of the housing 001. Then, the operator conveys the material from the upper opening of the housing 001 into the interior of the housing 001. The top cover 002 is installed on the upper end of the housing 001. During the installation of the top cover 002, the protrusion 203 at the lower end of the column 202 slides into the groove 303. Then, according to the required particle size of the material to be ground, the grinding disc 101 slides down a corresponding distance, thereby adjusting the gap between the inner wall of the grinding disc 101 and the lower end of the grinding head 304. Then, the material falls into the gap between the grinding disc 101 and the grinding head 304. The column 202 drives the protrusion 203 to rotate. The protrusion 203 pushes the vertical rod 003 to rotate through the groove 303, so that the vertical rod 003 drives the grinding head 304 to rotate. Through the cooperation between the rotating grinding head 304 and the grinding disc 101, the material is ground. The ground material falls through the holes inside the grinding disc 101. At the same time, when the grinding head 304 and the grinding disc 101 are grinding the material, the use of ceramic material for the grinding head 304 and the grinding disc 101 can significantly improve their longevity and corrosion resistance. The housing 001 is handheld.

[0023] The side wall of housing 001 is threadedly connected to a movable shell 102, and the side wall of housing 001 is slidably connected to a movable ring 103. The movable ring 103 is rotatably connected to the inside of the movable shell 102. By manually rotating the movable shell 102 through the thread that mates with the inner wall of the movable shell 102, the movable shell 102 causes the movable ring 103 to slide longitudinally.

[0024] Both sides of the housing 001 are provided with sliding grooves 105. A connecting rod 104 is slidably connected inside the sliding groove 105. One end of the connecting rod 104 is fixedly connected to the side wall of the grinding disc 101, and the other end of the connecting rod 104 is fixedly connected to the inner wall of the movable ring 103. When the movable ring 103 slides longitudinally, it drives the grinding disc 101 to slide longitudinally through the connecting rod 104. At the same time, the inner wall of the movable ring 103 fits against the side wall of the housing 001, and the sliding groove 105 on the side wall of the housing 001 is blocked by the movable ring 103.

[0025] The upper end of the housing 001 is provided with a slot 106. The upper cover 002 is threadedly connected to the slot 106. The slot 106 is used to position the upper cover 002. Then, the upper cover 002 is manually rotated through the thread that mates with the inner wall of the slot 106 to install the upper cover 002 into the slot 106.

[0026] A motor 201 is fixedly connected inside the top cover 002. The output end of the motor 201 is fixedly connected to the upper end of the column 202, and the column 202 is driven to rotate by the motor 201.

[0027] A ring plate 301 is rotatably connected to the side wall of the vertical rod 003. Multiple horizontal rods 302 are fixedly connected to the side wall of the ring plate 301. The multiple horizontal rods 302 are arranged in a circular array. The ends of the horizontal rods 302 are fixedly connected to the inner wall of the housing 001. The horizontal rods 302 and the housing 001 are fixedly connected by bolts. The ring plate 301 is supported by the multiple horizontal rods 302, and the ring plate 301 is also supported to facilitate the rotation of the vertical rod 003 inside the housing 001.

[0028] In this invention, when grinding materials is required, the operator conveys the material from the upper opening of the housing 001 into the housing 001, and then threads the upper cover 002 into the groove 106, thus installing the upper cover 002 onto the upper part of the housing 001. During the installation of the upper cover 002, the protrusion 203 at the lower end of the column 202 slides into the groove 303. Subsequently, according to the required particle size of the material to be ground, the movable housing 102 is manually rotated, causing the movable housing 102 to drive the movable ring 103 to slide downward. The movable ring 103 drives the grinding disc 101 to slide downward through the connecting rod 104, thereby adjusting the distance between the inner wall of the grinding disc 101 and the lower end of the grinding head 304. The material falls between the grinding disc 101 and the grinding head 304, and is driven by the motor 201 to rotate the column 202. The column 202 drives the protrusion 203 to rotate, and the protrusion 203 pushes the vertical rod 003 to rotate through the groove 303, so that the vertical rod 003 drives the grinding head 304 to rotate. Through the cooperation between the rotating grinding head 304 and the grinding disc 101, the material is ground. The ground material falls through the holes inside the grinding disc 101. At the same time, when the grinding head 304 and the grinding disc 101 are grinding the material, the use of ceramic material for the grinding head 304 and the grinding disc 101 can significantly improve their longevity and corrosion resistance.

[0029] When it is necessary to clean the inside of the housing 001, manually rotate the top cover 002 to unscrew it from the inside of the slot 106, thereby removing the top cover 002 from the top of the housing 001. At the same time, the protrusion 203 slides out from the inside of the groove 303. Then, remove the bolts between the crossbar 302 and the housing 001, and remove the vertical bar 003 from the inside of the housing 001. Then, the grinding disc 101 inside the housing 001, the lower end of the top cover 002, and the surface of the vertical bar 003, i.e., the lower end grinding head 304, can be cleaned individually.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
