Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tipping paper technology, and in particular relates to a pulping machine for cigarette tipping paper base paper. Background Technology
[0002] In modern papermaking technology, beating is a crucial step. It is a process that uses mechanical action to treat pulp fibers suspended in water, giving them the characteristics required for production on a paper machine and ensuring that the produced paper meets the expected quality. Physical methods can be used to treat pulp fibers in water with a beating machine, subjecting the fibers to shear force, changing the fiber morphology, and giving the pulp certain properties to ensure that the paper produced meets the expected quality requirements.
[0003] Existing pulpers typically use two grinding discs that rotate at different speeds or in opposite directions (i.e., reverse rotation), or one disc rotates while the other remains stationary. The pulper includes a housing into which the raw material to be pulped is fed through a feed pipe. The material then flows in through a feed inlet on the feed disc on the feed side. The problem with this type of pulper is that the feed, entering the pulper off-center, can move not only as needed towards the periphery of the grinding discs but also towards the center, where material may accumulate. This negatively impacts the material distribution within the pulper, potentially leading to uneven feeding and turbulence, resulting in higher energy consumption per unit area and lower productivity. Therefore, improvements to the material distribution within the pulping zone of the pulper are necessary. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned technical problems by providing a tobacco tipping paper pulping machine that better distributes the feed material to the grinding zone, reduces fluctuations and unstable flow of the feed material, and ultimately improves production efficiency and reduces unit energy consumption.
[0005] In view of this, the present invention provides a pulping machine for cigarette tipping paper base paper, the pulping machine comprising:
[0006] The housing has a feed pipe connected to it for the raw materials to enter;
[0007] The grinding disc has two grinding discs arranged opposite each other. The grinding disc has an annular grinding zone for grinding raw materials. Grinding teeth are arranged in the grinding zone. The gap between the tops of the grinding teeth of the two grinding discs is the grinding space. The grinding disc has a raw material inlet. A blocking block is arranged in the center of the grinding disc. The blocking block is used to reduce the accumulation of raw materials in the center of the grinding disc after the raw materials enter from the raw material inlet.
[0008] A drive motor is used to drive one of the grinding discs to rotate.
[0009] In this technical solution, a blocking block is formed between the centers of the two grinding discs, which concentrates the raw material feeding towards the edge of the grinding discs. This allows for better distribution of the feed material to the grinding zone, reducing fluctuations and unstable flow in the material feed, ultimately improving production efficiency and reducing unit energy consumption.
[0010] Furthermore, the blocking block is fixedly disposed at the center of one of the grinding discs, the blocking block is higher than the grinding teeth, and the distance from the blocking block to the surface of the other grinding disc is between 0.1mm and 0.2mm.
[0011] In this technical solution, the gap can make the gap between the centers of the two grinding discs very small, reducing the accumulation of raw materials in the center of the grinding discs, and can also ensure that the two grinding discs do not contact each other, thus ensuring safety during grinding.
[0012] Furthermore, the raw material inlets include multiple inlets that are evenly distributed circumferentially, the outer end of the blocking block extends to the space between two adjacent raw material inlets, and the edge of the blocking block is also provided with a clearance notch to make way for each raw material inlet.
[0013] Furthermore, the grinding zone includes a coarse grinding zone, a fine grinding zone, and a slag-reducing zone arranged sequentially from the center to the edge of the grinding disc. The coarse grinding zone, fine grinding zone, and slag-reducing zone are all annular. The coarse grinding zone, fine grinding zone, and slag-reducing zone are respectively provided with coarse grinding teeth, fine grinding teeth, and slag-reducing teeth. The height of the fine grinding teeth is higher than the height of the coarse grinding teeth, and the height of the coarse grinding teeth is higher than the slag-reducing teeth.
[0014] Furthermore, the gap between the tips of the grinding teeth in the fine grinding zone of the two grinding discs is 0.3mm-0.6mm, the gap between the tips of the grinding teeth in the loosening zone is 1mm-1.5mm, and the gap between the tips of the grinding teeth in the loosening zone is 0.6mm-0.9mm.
[0015] In this technical solution, after the raw material enters, it first enters the coarse grinding zone where it is ground by the coarse grinding teeth on two grinding discs that are far apart. Then it enters the fine grinding zone where it is ground by the fine grinding teeth on two grinding discs that are closest to each other. Finally, it enters the disintegration zone where the coarse grinding teeth on the two grinding discs are far apart, which makes it easier to disperse the fiber bundles formed by fine grinding with a lower intensity force and avoid over-grinding of the fibers.
[0016] Furthermore, the width of the fine grinding zone is greater than the width of the coarse grinding zone, and the width of the coarse grinding zone is greater than the width of the loosening zone.
[0017] In this technical solution, the time allocation of the three steps of coarse grinding, fine grinding and delamination can be controlled by setting the width of the coarse grinding zone, fine grinding zone and delamination zone.
[0018] Furthermore, the rough grinding teeth, fine grinding teeth, and sparse grinding teeth are staggered in the circumferential direction.
[0019] In this technical solution, the material can be guided to flow evenly into the next area during the rotation process.
[0020] Furthermore, the grinding teeth are provided with extending dispersing protrusions on both sides.
[0021] In this technical solution, the decomposing bumps can further break up the fiber bundles formed by fine grinding, thus avoiding over-grinding of the fibers.
[0022] The beneficial effects of this utility model are:
[0023] 1. A blocking block is formed between the centers of the two grinding discs, which concentrates the raw material feed towards the edge of the grinding discs. This allows for better distribution of the feed material to the grinding zone, reducing fluctuations and unstable flow of the material feed, ultimately improving production efficiency and reducing unit energy consumption.
[0024] 2. After the raw material enters, it first enters the coarse grinding zone where it is ground by the coarse grinding teeth on the two grinding discs that are far apart. Then it enters the fine grinding zone where it is ground by the fine grinding teeth on the two grinding discs that are closest together. Finally, it enters the disintegration zone where the coarse grinding teeth on the two grinding discs are far apart, which makes it easier to break up the fiber bundles formed by fine grinding with a lower intensity force and avoid over-grinding the fibers.
[0025] 3. By setting the width of the coarse grinding zone, fine grinding zone, and descaling zone, the time allocation of the three steps of coarse grinding, fine grinding, and descaling can be controlled.
[0026] 4. The grinding teeth for coarse grinding, fine grinding, and loosening are staggered in the circumferential direction. This allows the material to be guided evenly into the next zone during rotation. Attached Figure Description

[0037] Example 1:
[0038] like Figure 1-3 As shown, the pulping machine includes:
[0039] The housing 1 is connected to a feed pipe 2 for feeding raw materials.
[0040] There are two grinding discs 3, which are arranged opposite each other. The grinding discs 3 have an annular grinding zone for grinding raw materials. Grinding teeth are provided in the grinding zone. The gap between the tops of the grinding teeth of the two grinding discs 3 is the grinding space 4. The grinding discs 3 have a raw material inlet 7. A blocking block 5 is provided in the center of the grinding discs 3. The blocking block 5 is used to reduce the accumulation of raw materials in the center of the grinding discs 3 after the raw materials enter from the raw material inlet 7.
[0041] A drive motor 6 is used to drive one of the grinding discs 3 to rotate.
[0042] A blocking block 5 is formed between the centers of the two grinding discs 3, which causes the raw material to be concentrated towards the edge of the grinding discs 3. Therefore, the feed material can be better distributed to the grinding zone, reducing fluctuations and unstable flow of the feed material, and ultimately improving production efficiency and reducing unit energy consumption.
[0043] The blocking block 5 is fixedly installed at the center of one of the grinding discs 3. The blocking block 5 is higher than the grinding teeth, and the distance from the blocking block 5 to the surface of the other grinding disc 3 is between 0.1mm and 0.2mm. This gap can make the gap between the centers of the two grinding discs 3 very small, reducing the accumulation of raw materials in the center of the grinding discs 3, and also ensure that the two grinding discs 3 do not contact each other, thus ensuring safety during grinding.
[0044] The raw material inlets 7 include multiple inlets and are evenly distributed around the circumference. The outer end of the blocking block 5 extends to the space between two adjacent raw material inlets 7. The edge of the blocking block 5 is also provided with a clearance notch 8 to make way for each raw material inlet 7.
[0045] The grinding zone includes a coarse grinding zone 9, a fine grinding zone 10, and a loosening zone 11 arranged sequentially from the center to the edge of the grinding disc 3. The coarse grinding zone 9, the fine grinding zone 10, and the loosening zone 11 are all annular. The coarse grinding zone 9, the fine grinding zone 10, and the loosening zone 11 are respectively provided with coarse grinding teeth 12, fine grinding teeth 13, and loosening grinding teeth 14. The height of the fine grinding teeth 13 is higher than the height of the coarse grinding teeth 12, and the height of the coarse grinding teeth 12 is higher than the height of the loosening grinding teeth 14.
[0046] The gap between the grinding teeth tips in the fine grinding zone 10 of the two grinding discs 3 is 0.3mm-0.6mm, the gap between the grinding teeth tips in the dispersing zone 11 is 1mm-1.5mm, and the gap between the grinding teeth tips in the dispersing zone 11 is 0.6mm-0.9mm. After the raw material enters, it first enters the coarse grinding zone 9 and is ground by the coarse grinding teeth 12 on the two grinding discs 3 that are far apart. Then it enters the fine grinding zone 10 and is ground by the fine grinding teeth 13 on the two grinding discs 3 that are closest to each other. Finally, it enters the dispersing zone 11. The coarse grinding teeth 12 on the two grinding discs 3 in the dispersing zone 11 are farthest apart, which makes it easier to disperse the fiber bundles formed by fine grinding with a lower intensity force and avoid over-grinding the fibers.
[0047] The width of the fine grinding zone 10 is greater than the width of the coarse grinding zone 9, and the width of the coarse grinding zone 9 is greater than the width of the loosening zone 11. By setting the widths of the coarse grinding zone 9, the fine grinding zone 10, and the loosening zone 11, the time allocation of the three steps of coarse grinding, fine grinding, and loosening can be controlled.
[0048] The coarse grinding teeth 12, the fine grinding teeth 13, and the loosening grinding teeth 14 are staggered in the circumferential direction. This allows the material to be guided along its flow direction during rotation. Figure 3 The direction indicated by the middle arrow is evenly moving into the next area.
[0049] The grinding teeth 14 have extending dispersing protrusions 15 on both sides. The dispersing protrusions 15 can further disperse the fiber bundles formed by fine grinding, avoiding over-grinding of the fibers.
[0050] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
