Abstract
Description
Technical Field
[0001] This utility model relates to the field of polishing machines, and in particular to a dual-roll polishing machine that does not clog chaff and can be used in both series and parallel applications. Background Technology
[0002] Twin-roll polishing machines are used in grain processing and typically have two modes: series and parallel. In series mode, the material passes through two rollers sequentially. Sufficient processing time on each roller is desirable for better polishing results. A slower rotational speed allows for longer residence time on the rollers, resulting in a more thorough polishing process. In parallel mode, both rollers rotate rapidly simultaneously to increase production efficiency and process large quantities of material quickly. A higher rotational speed increases the linear velocity of the rollers, allowing for the processing of more material per unit time.
[0003] Current dual-roll polishing machines typically have two or more drive sources installed at one end of the two rollers. When the rollers are connected in series, the speed of the power source is divided into low speed and high speed, which achieves more thorough polishing. When the rollers are connected in parallel, the speed of the power source is the same, which can process a large amount of material. However, multiple power sources are required to drive them separately, which cannot reduce energy consumption and operating costs.
[0004] Therefore, it is necessary to provide a dual-roll polishing machine that can be used in both series and parallel applications without clogging to solve the above-mentioned technical problems. Utility Model Content

A second series cross shaft 19 is movably connected inside the series box 16. The second series cross shaft 19 passes through the series box 16 and extends into the inside of the series box 16. A small gear 20 is fixedly connected to the outside of the second series cross shaft 19. The first series cross shaft 17 is inserted into the other end of the first propulsion mechanism 4.

The other end of the connecting chamber 21 is fixedly connected to the second polishing chamber 13.
[0026] Different textures are provided on the inner walls of the first polishing chamber 5 and the second polishing chamber 13 to polish the surface of the rice grains when they are pushed in. The first pushing mechanism 4 and the second pushing mechanism 12 are equipped with a auger, which uses the characteristics of the auger to continuously transport the rice grains. When connected in parallel, the two parallel gears 11 mesh and rotate, and since they have the same diameter, they can achieve rapid polishing. When connected in series, the large gear 18 meshes with the small gear 20 and rotates. The large gear 18 rotates slowly and can perform preliminary processing. The connecting chamber 21 is opened so that the rice grains flow into the second polishing chamber 13 and the rice grains are subjected to secondary fine processing by the rapid rotation of the small gear 20.
[0027] The inner wall of the polishing machine 1 is fixedly connected to a straight block 22. The outer side of the straight block 22 is slidably connected to a first groove 23.

[0028] During operation, the anti-blocking mechanism 28 continuously pushes the inclined plate 24 horizontally back and forth. The cooperation between the straight block 22, the first slide 23, the convex block 26, and the second slide 25 restricts the inclined plate 24 and maintains its horizontal back and forth movement.
[0029] The polishing machine 1 is externally fixedly connected to a side cylinder 29, and a bolt 30 is internally threaded to the side cylinder 29. A baffle 31 is externally movably connected to the bolt 30. The bolt 30 passes through the baffle 31 and extends to the outside of the baffle 31.

[0030] Tighten or loosen bolt 30 using a wrench. When it is necessary to replace the series column 15, loosen bolt 30 and remove baffle 31. Move parallel column 8 to one side of the mountain groove 7, then move series column 15 to the middle position of mountain groove 7. Use baffle 31 to fix series column 15, and use rubber block 32 to squeeze and fix series column 15 or parallel column 8.
[0031] The connecting chamber 21 is slidably connected to the insert plate 33, and the insert plate 33 is fixedly connected to the outside of the pull rod 34. The inner wall of the polishing machine 1 is fixedly connected to the fixing plate 35, and the fixing plate 35 is slidably connected to the pull rod 34.
[0032] The pull rod 34 can control the flow of rice grains in the connecting chamber 21 by controlling the insert plate 33. When parallel connection is required, the insert plate 33 is pushed into the connecting chamber 21 to block the flow. When series connection is required, the insert plate 33 is pulled out of the connecting chamber 21 to allow the rice grains to flow.
[0033] A first material pipe 36 is fixedly connected to the outside of the first polishing chamber 5, a first material discharge pipe 37 is fixedly connected to the outside of the first polishing chamber 5, a second material discharge pipe 38 is fixedly connected to the outside of the second polishing chamber 13, and a second material pipe 39 is fixedly connected to the outside of the second polishing chamber 13.
[0034] Rice grains are fed through the first feed pipe 36 and the second feed pipe 39, allowing them to flow into the first polishing chamber 5 and the second polishing chamber 13 respectively. The rice grains in the first polishing chamber 5 and the second polishing chamber 13 are facilitated to flow out through the first discharge pipe 37 and the second discharge pipe 38. A valve is installed inside the first discharge pipe 37. In the series mode, the valve is closed, allowing the rice grains to flow from the first polishing chamber 5 into the second polishing chamber 13 sequentially through the connecting chamber 21. In the parallel mode, the valve on the first discharge pipe 37 is opened, and the connecting chamber 21 is closed using the insert plate 33, allowing the rice grains in the first polishing chamber 5 to flow out through the first discharge pipe 37, and the rice grains in the second polishing chamber 13 to flow out through the second discharge pipe 38.
[0035] The top of the support plate 6 is provided with a placement groove 40 and a tool groove 41.
[0036] When the parallel column 8 is displaced, the baffle 31 and bolt 30 are placed inside the placement slot 40 to prevent loss. The tool slot 41 contains some wrenches to facilitate the disassembly of the bolt 30.
[0037] The working principle of the non-clogging, parallel-parallel dual-roller polishing machine provided by this utility model is as follows: First, when processing a large amount of material, the operator manually pulls the handle 14 to push the parallel box 9 to the outside of the polishing machine 1, allowing the parallel cross shaft 10 to be inserted into the first propulsion mechanism 4. Simultaneously, both the first and second propulsion mechanisms 4 and 12 have cross grooves at one end, facilitating the insertion of the cross grooves with the parallel cross shaft 10, the first series cross shaft 17, and the second series cross shaft 19, enabling synchronous rotation with the first and second propulsion mechanisms 4 and 12. Then, when switching to parallel mode, the motor 3 is started to drive the first propulsion mechanism 4. As the first propulsion mechanism 4 rotates, the parallel gears 11 on the parallel cross shaft 10 rotate, transmitting kinetic energy to each other, causing the second propulsion mechanism 12 to rotate. Since the two parallel gears 11 have the same diameter, their rotation speeds are the same. Therefore, in large-scale production, to meet the demand for high output, the parallel mode allows for rapid rotation, greatly shortening the production cycle and improving production efficiency. Finally, when fine polishing is required, the motor 3 is turned off, the parallel box 9 is moved, and the series box 16 is moved to the polishing machine. Outside the machine 1, after aligning the first series cross shaft 17 and the second series cross shaft 19 with the first propulsion mechanism 4 and the second propulsion mechanism 12 respectively, the motor 3 is started again. When the large gear 18 on the first series cross shaft 17 rotates, it can mesh with the small gear 20 on the second series cross shaft 19 for transmission, so that the second propulsion mechanism 12 obtains power to rotate. Since the diameters of the large gear 18 and the small gear 20 are different, the large gear 18 rotates at a slower speed, allowing the material to undergo preliminary processing, such as removing larger impurities or performing a gentler grinding. The small gear 20... The high rotation speed allows for more precise polishing or further removal of minor imperfections, enabling step-by-step processing and improving processing quality. A connecting chamber 21 is installed between the first polishing chamber 5 and the second polishing chamber 13. When connected in parallel, the connecting chamber 21 is closed to prevent the material inside the first polishing chamber 5 and the second polishing chamber 13 from flowing out, thus preventing the material from flowing into the second polishing chamber 13 for reprocessing and avoiding incomplete breakage of rice grains. When connected in series, the connecting chamber 21 is opened, and after the initial processing in the first polishing chamber 5, the material flows into the second polishing chamber 13 for further processing.
[0038] Compared with related technologies, the dual-purpose series-parallel polishing machine that does not clog rice bran provided by this utility model has the following beneficial effects:
[0039] This utility model provides a non-clogging dual-purpose series-parallel double-roll polishing machine. It utilizes a motor 3, a first propulsion mechanism 4, a second propulsion mechanism 12, a parallel cross shaft 10, a parallel gear 11, a first series cross shaft 17, a large gear 18, a second series cross shaft 19, and a small gear 20 in mutual cooperation. By selecting different gear combinations, the speed ratio between the two rollers can be easily adjusted to adapt to different processing requirements. Whether it's sequential processing in series mode or simultaneous rapid rotation in parallel mode, the optimal processing effect can be achieved by adjusting the gears. Furthermore, using different gears reduces installation complexity and maintenance workload, making equipment debugging and troubleshooting easier, thus improving the reliability and availability of the equipment.
