Description

Technical Field

[0001] This utility model relates to the field of enamel glaze processing technology, and in particular to a enamel glaze grinding mill that facilitates material unloading. Background Technology

[0002] A grinding mill transforms large lumps or granules into extremely fine and uniform powder through mechanical grinding. The finely ground enamel glaze can then be coated more evenly onto the surface of the metal blank. During the subsequent high-temperature firing process, the fine glaze powder fully melts and flows, bonding tightly with the metal blank to form a smooth, dense enamel coating with excellent corrosion resistance, wear resistance, and decorative properties.

[0003] When grinding enamel glaze raw materials, the inner wall of the grinding mill casing is prone to material adhesion. Due to the inherent stickiness of the raw materials, under the influence of the heat and mechanical forces generated during grinding, they will adhere firmly to the inner wall of the casing, and the accumulation thickness gradually increases over time. This not only prevents a large amount of raw material from participating in normal grinding, resulting in material waste, but also makes the actual amount of raw material participating in grinding unstable, affecting grinding efficiency and product quality consistency.

[0004] In traditional grinding mills, raw materials are prone to clogging in the feed channels or gaps inside the machine during the unloading process. Enamel glaze raw materials come in various forms, including lumps and granules. Under the influence of gravity and mechanical agitation, raw material particles of different shapes and sizes are squeezed and interlocked, easily forming blockage points in narrow feed areas. Once a blockage occurs, operators must stop the machine for cleaning, which not only consumes a lot of manpower and time but also interrupts the production process, reduces production efficiency, and increases production costs.

[0005] Furthermore, traditional grinding mills struggle to ensure uniform material distribution during unloading. Inside the mill, material distribution is often uneven, with excessive accumulation in some areas and insufficient material in others, leading to unstable unloading speeds. Uneven feeding results in inconsistent grinding force from the grinding rollers, causing significant variations in the particle size of the produced enamel glaze. This fails to meet the stringent particle size uniformity requirements of high-end products, limiting their application in high-precision fields. Utility Model Content

[0006] The purpose of this invention is to provide a enamel glaze grinding mill that facilitates material unloading. By using this device, the above-mentioned problems can be solved.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grinding mill for enamel glaze that is easy to unload, including a grinding mill casing, a motor and a grinding roller. The motor is installed at the rear end of the grinding mill casing. The grinding roller is rotatably arranged inside the grinding mill casing. The shaft of the motor extends into the interior of the grinding mill casing and is fixedly connected to the end of the grinding roller. A cover is installed at the front end of the grinding mill casing. An outer shell is fixed to the outside of the grinding mill casing. A striking component is arranged on the outer periphery of the outer shell.

[0008] Preferably, the striking component includes a support block fixed to the outer periphery of the outer shell, connecting rods are evenly spaced inside the support block, one end of the connecting rod extends into the interior of the outer shell, striking blocks are evenly spaced inside the outer shell, the end of the striking block is fixedly connected to the end of the connecting rod, a stop block is fixed to the other end of the connecting rod, the stop block is located at the end of the support block, and a spring is wound around the outside of the connecting rod, with the spring placed inside the support block.

[0009] Preferably, brackets are fixed at equal intervals on the outside of the support block, and eccentric wheels are rotatably arranged between the brackets. The eccentric wheels are located at the end of the block and abut against its outer wall.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model provides a convenient enamel glaze grinding mill. A motor drives an eccentric wheel to rotate, causing a striking block to continuously and reciprocate against the outer wall of the mill casing, generating high-frequency vibrations. On one hand, this effectively prevents enamel glaze raw materials from adhering to the inner wall of the mill casing, avoiding accumulation and ensuring smooth discharge, significantly improving material utilization and ensuring more material participates in grinding, reducing waste. On the other hand, the vibration reduces friction and adhesion between raw material particles, preventing blockages in the internal discharge channels and gaps, ensuring smooth and unobstructed discharge, maintaining stable and continuous grinding without frequent shutdowns for cleaning, greatly improving production efficiency. Furthermore, the vibration from the striking action promotes even distribution of the raw material within the casing, making discharge more uniform and orderly. Attached Figure Description

[0020] 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.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figures 1 to 6 As shown, the present invention discloses a pulverizer for easy unloading of enamel glaze, comprising a pulverizer housing 1, a motor 2, and a grinding roller 5. The motor 2 is installed at the rear end of the pulverizer housing 1, and the grinding roller 5 is rotatably arranged inside the pulverizer housing 1. The rotating shaft of the motor 2 extends into the interior of the pulverizer housing 1 and is fixedly connected to the end of the grinding roller 5. A housing cover 3 is installed at the front end of the pulverizer housing 1, and an outer shell 4 is fixed to the outside of the pulverizer housing 1. A striking component is provided on the outer periphery of the outer shell 4.

[0023] The striking assembly includes a support block 41 fixed to the outer periphery of the outer shell 4. Connecting rods 42 are evenly spaced inside the support block 41. One end of the connecting rod 42 extends into the interior of the outer shell 4. Striking blocks 43 are evenly spaced inside the outer shell 4. The end of the striking block 43 is fixedly connected to the end of the connecting rod 42. A stop block 44 is fixed to the other end of the connecting rod 42. The stop block 44 is located at the end of the support block 41. A spring 45 is wound around the outside of the connecting rod 42. The spring 45 is placed inside the support block 41.

[0024] Support blocks 41 are fixed with brackets 46 at equal intervals on the outside. Eccentric wheels 47 are rotatably arranged between the brackets 46. The eccentric wheels 47 are located at the end of the abutment block 44 and abut against its outer wall. A second motor 48 is installed at the bottom of the brackets 46. The second motor 48 is located below the eccentric wheels 47. The rotating shaft at the top of the second motor 48 is fixedly connected to the rotating shaft of the eccentric wheels 47.

[0025] There is a gap between the mill housing 1 and the outer shell 4. The support blocks 41 are evenly spaced on the outer periphery of the outer shell 4, and the connecting rods 42 are evenly spaced inside the support blocks 41.

[0026] Specifically, the striking block 43 is positioned in the gap between the mill housing 1 and the outer casing 4, ensuring the movement of the striking block 43 without hindering the overall compact structure of the mill. The impact surface of the striking block 43 has numerous protrusions, is hard and flat, and can deliver precise and powerful impacts to the outer wall of the mill housing 1 during reciprocating movement.

[0027] The operator opens the box cover 3, and then pours the pre-prepared enamel glaze raw materials into the open internal space of the grinding mill box 1.

[0028] After the raw materials are fed in, the operator starts motor 2. The motor shaft rotates rapidly, driving the grinding roller 5 to rotate smoothly inside the mill housing 1 via the transmission device. The surface of the grinding roller 5 is covered with regularly arranged teeth. As it rotates, the enamel glaze raw material is drawn into the gaps between the rollers and between the rollers and the inner wall of the housing. Under the action of strong extrusion and friction, the raw material is continuously crushed and ground, and the fine powder gradually spreads inside the housing.

[0029] However, during the grinding process, some raw material begins to adhere to the inner wall of the mill casing 1. The operator starts motor 2 48. After motor 2 48 starts, its output shaft drives eccentric wheel 47 to start rotating at high speed. The circumferential profile of eccentric wheel 47 is irregular. As it rotates, the protruding part gradually approaches and pushes against block 44. Under the push of eccentric wheel 47, block 44 pushes connecting rod 42 forward along a predetermined track. During the movement of connecting rod 42, the striking block 43 connected to the other end is pushed forward and strikes heavily against the outer wall of mill casing 1. At the same time, connecting rod 42 also compresses spring 45, causing it to gradually contract, and spring 45 accumulates elastic potential energy.

[0030] As the eccentric wheel 47 continues to rotate, the protruding part moves away from the abutment block 44, and the pressure on the abutment block 44 disappears instantly. At this moment, the spring 45, which has accumulated elastic potential energy, quickly rebounds, releasing a strong elastic force that drives the connecting rod 42 to move backward along the track. The backward movement of the connecting rod 42 causes the striking block 43 to quickly move away from the outer wall of the mill housing 1. The eccentric wheel 47 rotates in this cyclical manner, and the striking block 43 continuously impacts the outer wall of the mill housing 1. Each impact causes the mill housing 1 to produce a subtle but effective vibration. Under this continuous vibration, the raw material adhering to the inner wall of the mill housing 1 detaches from the inner wall and falls back into the grinding area to continue participating in the grinding process, greatly improving the efficiency and quality of enamel glaze grinding.

[0031] During the grinding process of enamel glaze raw materials, raw materials are easily attached to the inner wall of the machine. The vibration generated by the tapping can make these attached raw materials fall off, preventing the raw materials from sticking and accumulating on the inner wall of the machine, ensuring that the raw materials can continuously participate in the grinding, which helps to improve grinding efficiency and raw material utilization.

[0032] The continuous tapping causes the machine casing to vibrate, which reduces the friction and adhesion between the falling raw material particles, allowing the raw material to flow more smoothly downwards and preventing blockages in the material feeding channels or gaps inside the machine casing, thus ensuring the continuity of the entire grinding process.
