Description

Technical Field

[0001] The invention relates to the technical field of pulverizers, in particular to a bamboo pulverizer for paper production which can accelerate material feeding. Background Art

[0002] Bamboo is a fast-growing, renewable resource. As people pay more attention to environmental protection and sustainable development, bamboo is increasingly used. However, untreated bamboo is often not convenient for direct use in terms of size and shape, and needs to be crushed to meet the needs of different fields, such as papermaking, wood-based panel manufacturing, biomass energy, etc. Before the emergence of bamboo crushers, bamboo processing mainly relied on manual felling and simple cutting tools, which was inefficient and labor-intensive. Moreover, this method was difficult to process bamboo into uniform particles or powder, and could not meet the specifications of modern industrial production for bamboo raw materials. With the continuous advancement of mechanical manufacturing technology and automation technology, bamboo crushers have been developed and applied. They can efficiently crush bamboo into materials of different particle sizes, improving the utilization rate and processing efficiency of bamboo. At the same time, some advanced bamboo crushers also have functions such as automatic control and safety protection, which further improve the performance and reliability of the equipment. When the existing bamboo crusher for paper production is used, it generally cuts a long bamboo into multiple shorter bamboo sections, such as cutting a bamboo of several tens of meters into multiple 1m or 2m bamboo sections, and then crushes them. However, there are still some problems in the use of the existing bamboo crusher for paper production, specifically: 1. The existing bamboo crusher for paper production is not convenient to increase the feeding speed when in use. This is because the length of the crushing roller inside the crusher is much larger than the outer diameter of the bamboo. During the crushing process of the bamboo, only a partial part of the crushing roller is used, which is not conducive to improving the crushing efficiency. This also limits the feeding speed of the bamboo when feeding; 2. When the existing bamboo crusher for paper production is in use, the grinding part is prone to jamming, causing the feeding part to be blocked by bamboo powder, resulting in failure to feed smoothly.

[0003] Therefore, a bamboo pulverizer for paper production that can accelerate the feeding is needed to solve the above problems. Summary of the invention

[0019] See also Figure 1-11 , the present invention provides the following technical solutions: Embodiment 1:

[0020] In order to solve the problem that the bamboo crusher for paper production in the past cannot reduce the crushing difficulty and cannot improve the cutting efficiency, and thus it is not convenient to increase the feeding speed, the following technical solution is provided, specifically, a bamboo crusher for paper production that can accelerate feeding, including a support tube 1, a feeding assembly, a crushing assembly and a grinding assembly, three support feet 2 are distributed at equal angles on the outer side of the lower end of the support tube 1, and the upper surface of the support tube 1 is connected to the connecting tube 4 through support blocks 3 distributed at equal angles, the upper end of the connecting tube 4 is threadedly connected with a feeding tube 5, and the feeding tube 5 is provided with two groups of limiting elastic sheets 6 at equal angles, the limiting elastic sheets 6 are used to position the bamboo to ensure that the feeding positions of bamboos of different thicknesses are the same, a feeding assembly is also provided in the feeding tube 5, and the feeding assembly is provided between the two groups of limiting elastic sheets 6, a dividing frame 12 is installed on the inner side of the upper end of the connecting tube 4, and the inside of the connecting tube 4 is sequentially provided with a crushing assembly and a grinding assembly from top to bottom, and the inner side of the connecting tube 4 is connected with the inner side of the support tube 1.

[0021] The feeding assembly includes a square cover 7, a motor frame 8, a servo motor 9, an active roller 13, a driven roller 22, a slider 23, a shaft 24, a shaft tube 25, a spring 26, a moving block 27, a slide 28 and a displacement groove 29. The feed pipe 5 is provided with two symmetrical square through grooves, and the outer sides of the two square through grooves are fixedly connected with square covers 7. The two square covers 7 are provided with slides 28, and only the slide 28 on the right side of the square cover 7 runs through the inner and outer sides thereof. Two sliders 23 are slidably connected in each slide 28, and the two sliders 23 are respectively fixedly connected with coaxial shafts. The rod 24 and the shaft tube 25 are movably nested on the outside of the coaxial shaft rod 24, and the shaft tube 25 is provided with a spring 26 on the outside of the shaft rod 24 and the shaft tube 25. The two ends of the spring 26 are respectively connected between the two sliders 23 in the same slide groove 28.

The slider 23 slides in the slide groove 28 to adjust the distance between the active roller 13 and the driven roller 22, and cooperates with the limiting elastic sheet 6 to realize the bamboo joint. Preliminary positioning is performed to ensure that the axis of the bamboo joint is roughly in line with the axis of the dividing frame 12, and then the dividing frame 12 can divide the bamboo joint into several bamboo pieces, so as to reduce the difficulty of crushing.

The cutting knives 15 are provided in 5 groups, and the number of cutting knives 15 in each group increases proportionally from top to bottom. Five groups of cutting knives 15 are provided, and the number of cutting knives 15 in each group increases proportionally from top to bottom, which can cut bamboo chips step by step, which can not only reduce the difficulty of crushing, improve the cutting efficiency, and gradually crush the bamboo chips, but also reduce the pressure of the cutting knife 15, and prevent The cutting knife 15 is prevented from being damaged by a large pressure, thereby relatively ensuring that the cutting knife 15 can operate stably for a long time. The dispersion cone 14 is conical, and the inner side of the connecting pipe 4 corresponding to its outer surface is the upright truncated cone-shaped part in the middle and lower part of the inner side of the connecting pipe 4. The inner side of the support pipe 1 is an inverted truncated cone through hole that passes through from top to bottom. The middle and lower part of the inner side of the connecting pipe 4 is arranged from top to bottom as upright truncated cone, inverted truncated cone and inverted truncated cone-shaped hole grooves. The opening diameter of the lower end of the connecting pipe 4 is smaller than the diameter of the upper surface of the support pipe 1. Through the arrangement of a variety of truncated cone structures and the dividing frame 12, after the bamboo section is divided into a plurality of bamboo pieces, the plurality of bamboo pieces are scattered through the upper end of the dispersion cone 14, thereby avoiding a plurality of bamboo pieces from gathering at the same position for crushing, and making full use of most of the cutting knives 15, thereby improving the cutting efficiency, reducing the difficulty of crushing, and improving the efficiency of crushing. By reducing the difficulty of crushing and improving the efficiency of crushing, the speed of feeding can be greatly improved. Embodiment 2:

[0023] In order to solve the problem that the grinding part of the bamboo crusher for paper production is easily blocked by bamboo powder during use, which makes it difficult for the powdered bamboo material to fall smoothly, the grinding assembly includes a grinding roller 16, an inclined groove 19, a guide rod 20 and an adjusting block 21. The grinding roller 16 is coaxially arranged at the lower end of the dispersion cone 14, and the grinding roller 16 is penetrated by the shaft end of the servo motor 17. The shaft end of the servo motor 17 is provided with an inclined groove 19, and the inclined groove 19 is penetrated by the guide rod 20. The guide rod 20 is "n" shaped, and protrusions are arranged on both sides of the upper part of the guide rod 20, and the guide rod 20 is slidably connected with the strip groove arranged on the inner side of the grinding roller 16 through the protrusion. The guide rod 20 is slidably connected to the inner side of the grinding roller 16, so that when the shaft end of the servo motor 17 drives the guide rod 20 to rotate, the grinding roller 16 can be synchronously driven to rotate. The structure formed by the outer side of the grinding roller 16 and the inner side of the corresponding connecting tube 4 can be used to grind the crushed bamboo chips, which is convenient for grinding the bamboo chips into powder, thereby facilitating paper production. The end of the guide rod 20 is contacted and connected to the upper end of the adjustment block 21, and the adjustment block 21 is threadedly connected to the lower end of the grinding roller 16. The adjustment block 21 is movably penetrated by the shaft end of the servo motor 17, and the distance between the inner side of the adjustment block 21 and the shaft end of the servo motor 17 is not less than the horizontal width of the inclined groove 19. 1 / 2, the outer side of the lower end of the adjusting block 21 is a hexagonal prism, and the lower end of the adjusting block 21 is between the supporting tube 1 and the connecting tube 4, and the corresponding parts inside the grinding roller 16 and the connecting tube 4 are both set to be truncated, so that the crushed bamboo nodes can be ground into powder by the grinding roller 16 and the connecting tube 4, and then the powder falls into the inner side of the supporting tube 1 through the lower end of the connecting tube 4, and is finally discharged. Before grinding, the height of the guide rod 20 can be adjusted by rotating the adjusting block 21. When the height of the guide rod 20 is adjusted, the grinding roller 16 is no longer coaxial with the shaft end of the servo motor 17 through the inclined groove 19, which makes the grinding roller 16 do eccentric motion when the shaft end of the servo motor 17 rotates. The grinding roller 16 makes a relatively small eccentric movement, which can prevent the bamboo powder from blocking the gap between the lower end of the connecting tube 4 and the lower end of the grinding roller 16 to a certain extent. Even if the gap between the lower end of the connecting tube 4 and the lower end of the grinding roller 16 is blocked by the bamboo powder, the adjusting block 21 can be further rotated to increase the amplitude of the eccentric movement of the grinding roller 16, so that the bamboo powder can fall smoothly. The distance between the outer side of the grinding roller 16 and the inner side of the connecting tube 4 gradually decreases from top to bottom. By setting the distance, step-by-step grinding can be achieved to reduce the difficulty of grinding. The inner side of the grinding roller 16 is a through hole coaxial with it, and the support tube 1, the connecting tube 4, the feed pipe 5 and the dispersion cone 14 are coaxially arranged.
