Description

Technical Field

[0001] The present invention relates to the field of grain mills, and in particular, to a high-performance grain mill. Background Art

[0002] Grains include rice, wheat, millet, soybeans, and other miscellaneous grains. Cereals include rice, wheat, millet, soybeans, etc., mainly plant seeds and fruits. At the same time, there are various ways to consume grains. Among them, the method of grinding them into powder is quite popular. A grain mill is a mechanical device that grinds grains into powder. It plays a crucial role in agriculture, food processing, and household use. It is a key tool for converting grains into edible powders. The application range of grain mills is very wide, from large-scale flour mills to small household workshops. Even some families that pay attention to a healthy diet will choose to use a small mill to make fresh whole grain flour.

[0003] For example, in the "Mill" with the publication number CN02144342.4, in this device, through an advanced milling system, the material is milled and screened multiple times. It is recommended that the material pass through the double milling stage at least twice. There is no screening device between the double milling processes. After the double milling, they are respectively screened. Particularly advantageously, the corresponding new milling system is provided with at least two double milling channels, preferably made into an eight-roll mill. The new milling system is particularly advantageously a combination of an eight-roll and a four-roll mill. The screening surfaces of the double milling devices are respectively 20 - 50% larger.

[0004] Although the above-mentioned mill has certain advantages in milling efficiency, it still has certain drawbacks: during the use of the above-mentioned mill, after multiple uses, the component devices inside the mill are prone to wear. For example, the transmission between the fast roller and the slow roller wheel becomes loose, affecting the transmission effect. The distance between the fast roller and the slow roller shifts, making it impossible to effectively mill the grains and unable to adjust and maintain it conveniently, thus affecting the use and reducing the production efficiency.

[0026] The present invention provides a high-performance grain mill through improvement, and its working principle is as follows; 1. Before use, first, the roll gap needs to be adjusted. In the combined rolling state, tighten the coarse-adjusting nut 174, so that the pull rod 173 drives the disc spring 175 to move towards the fast roll two 12, pushing the slow-roll bearing seat 176 to approach the fast-roll bearing seat 179 against the spring force between the rolls. After the coarse adjustment is completed, the fine-tuning arm 171 should be perpendicular to the ground; 2. Then press the unlocking button and turn the fine-tuning handwheel 1710. When the fine-tuning handwheel 1710 rotates, it drives the fine-tuning arm 171 to swing. When the fine-tuning arm 171 swings, it drives the tensioning frame 172 to move. The tensioning frame 172 is connected to the pull rod 173. When the tensioning frame 172 moves, it drives the pull rod 173 to move. When the pull rod 173 moves, it drives the disc spring 175 towards the second fast roller 12, pushing the slow roller bearing seat 176 to approach the fast roller bearing seat 179 against the spring force between the rollers, so that the roll gap meets the process requirements; 3. To ensure the consistency of the roll gap along the length of the grinding roller, each flour mill is equipped with 4 sets of roll gap fine-tuning devices. Each set is adjusted unilaterally. A roll gap gauge is installed on the fine-tuning handwheel 1710, but it is not used as a measurement basis and is for reference only. After the flour mill is tested with materials and the roll gap is considered appropriate, the reading of the roll gap gauge is adjusted to 0. Finally, press the unlocking button again to fix the roll gap; 4. After the roll gap is adjusted properly, check whether the entire length of the scraping blade 148 is in contact with the grinding roller in the closed state. Use the light transmission method, a piece of paper strip or a feeler gauge for inspection. Clamp a thin paper strip between the scraping blade and the grinding roller at three points on the left, middle and right of the grinding roller (since the grinding roller has a crown, the two points on the left and right need to be 220 mm away from the end face of the grinding roller respectively). The degree of compression of the paper strip should be basically the same. Adjust the pressing force of the scraping blade 148 with the counterweight rod 142. In order to minimize the pressing force, the counterweight rod 142 should be moved as close as possible to the scraping blade 148, so that the wear of the scraping blade 148 can be minimized. The position of the counterweight rod 142 has been adjusted before leaving the factory; 5. If the scraping blade 148 is not completely in contact with the grinding roller, adjustments are needed. If the left or right side of the scraping blade 148 is not in contact with the grinding roller, loosen the wing nut 144 and adjust the left or right wing screw until the scraping blade 148 is in contact with the grinding roller. If the middle section of the scraping blade 148 is not in contact with the grinding roller, loosen the wing nut 144 and adjust the wing screws on both the left and right sides simultaneously until the entire length of the scraping blade 148 is in contact with the grinding roller. Each loosened wing nut 144 must be tightened again. During the production process, regularly check the wear of the scraping blade 148 to prevent the phenomenon of roller entanglement. After the scraping blade is worn, just adjust the wing nut 144 to make it contact the grinding roller; 6. The fast and slow rollers are driven by a toothed wedge belt. Before the flour mill runs, it is necessary to check the tightness of the toothed wedge belt. The tensioning of the tensioning wheel 76 is an elastic connection structure, which can automatically compensate for the slight changes of the toothed wedge belt during operation, ensuring both the transmission performance of the belt and improving the service life of the belt. The tightness of the belt must be adjusted after running continuously for 24 hours. When using a new toothed wedge belt, after the flour mill runs continuously for 240 - 300 hours, it is necessary to swap the positions of the two toothed wedge belts and adjust once; 7. If the toothed wedge belt loosens frequently, the fixed plate 7122 is pushed to move by the cylinder 7121. When the fixed plate 7122 moves, the support rod 74 is driven to move. When the support rod 74 moves, the swing frame 75 is driven to move. When the swing frame 75 moves, the tension pulley 76 is driven to move. By adjusting the position of the tension pulley 76, the tightness of the toothed wedge belt is adjusted, ensuring normal transmission between the fast and slow rollers. 8. When all the adjustments are completed, the flour mill can be operated by controlling the control panel, and the system enters the automatic mode. Automatic feeding is carried out for flour grinding, and the ground flour is discharged through the first hopper 9 and the second hopper 15.

[0027] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
