Technical Field

[0001] The present invention relates to the technical field related to fiberboard processing, and particularly relates to a fiberboard raw material mixing device and a using method thereof. Background Art

[0002] For the artificial board formed by interweaving wood cellulose fibers and made by using its inherent adhesive property, with the rapid development of China's economy and the continuous improvement of the urbanization rate, fiberboard products with stable quality, high environmental protection level, meeting differentiated needs and having safety flame retardant functions have broad market space. In the future, the rapid development of industries such as China's real estate, furniture, interior decoration, packaging, etc. and the completion and commissioning of fast-growing industrial timber raw material bases will drive the steady growth of the demand and export volume of fiberboards, and the proportion of fiberboard products in the total production of artificial boards will also increase significantly. Additives can be applied to the raw materials during the fiberboard manufacturing process, but existing mixing devices often use simple paddle rotation, and the filling direction of the additives is from top to bottom injection. This kind of mixing and stirring often encounters some problems in actual stirring:

[0003] The stirring area of the traditional paddle is small, it is difficult to cover the entire stirring area, and the top-to-bottom injection makes it take a certain time for the additives to penetrate into the lower layer. Even with the assistance of stirring to completely mix the raw materials and additives evenly, the time consumed will be relatively long. Summary of the Invention

[0004] (1) Technical Problems to be Solved

[0005] The present invention can solve problems such as the small stirring area of the traditional paddle, which is difficult to cover the entire stirring area, and the top-to-bottom injection, which takes a certain time for the additives to penetrate into the lower layer, resulting in a relatively long time for uniform mixing and easy uneven mixing in a relatively short time.

[0006] (2) Technical Solutions

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: A fiberboard raw material mixing device includes a mixing cylinder, a stirring device, a stirring outer ring, and a conveying device. A stirring device is installed in the middle of the mixing cylinder, a stirring outer ring is rotationally and cooperatively connected to the inner wall of the mixing cylinder, and a conveying device is connected between the upper end of the stirring device and the outer wall of the mixing cylinder.

[0008] The mixing cylinder includes a cylinder body, a bracket is installed at the bottom of the cylinder body, a feed inlet is opened at the upper end of the side wall of the cylinder body, and a closable discharge outlet is opened at the lower end of the side wall of the cylinder body.

[0009] The described stirring device includes a stirring column. The upper and lower ends of the horizontally rotating stirring column are in sealed rotational mating connection with the cylinder body. An input cavity is formed inside the stirring column. An in-depth nozzle that can move in and out and reset is arranged in the input cavity. Before the stirring group is unfolded, the in-depth nozzle is squeezed into the input cavity to temporarily block and seal the position of its spray outlet. Deformable stirring groups are arranged at the left and right ends of the stirring column. The lower end of the stirring group is connected to the stirring column by a pin shaft, and the upper end of the stirring group is connected to a sleeved ring by a pin shaft. The sleeved ring is sleeved on the stirring column up and down. The sealing ring and the descending rotating plate temporarily cut off the feed inlet, and the synchronously descending sleeved ring drives the stirring group to unfold and deform. The sleeved ring is installed at the lower end of the rotating plate. The rotating plate is horizontally rotatably arranged on the sealing ring. A connecting cylinder is connected between the sealing ring and the upper end of the cylinder body. The connection relationship among the connecting cylinder, the sealing ring, the rotating plate and the stirring column ensures the lifting of the sealing ring. The rotating plate can not only follow the lifting of the sealing ring but also follow the horizontal rotation of the stirring group, while ensuring the horizontal rotation of the stirring column. A connecting ring located below the stirring group is installed on the stirring column, and stirring plates are evenly installed on the connecting ring along its circumference.

[0010] The described stirring outer ring includes a rotating ring. The rotating ring is connected to the cylinder body in a rotational mating manner. Insertion plates are evenly installed along the circumference in the middle of the rotating ring. Mixing paddles are evenly installed along the circumference at the upper and lower ends of the rotating ring.

[0011] Among them, a ring gear is installed at the upper end of the stirring column. The ring gear meshes with a gear. The gear is installed on the output shaft of the motor. The motor is installed inside the cylinder body through a motor base.

[0012] Among them, the upper and lower ends of the input cavity are of open structures. The lower end of the input cavity is blocked by a sealing plate. When the input cavity contains additive residual liquid, the sealing plate can be opened to discharge the residual liquid and flush the input cavity from bottom to top.

[0013] Among them, the in-depth nozzle includes a spray head. The spray head is horizontally slidably arranged on the stirring column and is communicated with the input cavity. A sleeved spring is connected between the spray head and the inner wall of the input cavity. The sleeved spring plays a role in resetting. The sleeved spring always keeps a tendency to extend outward from the spray head. A flexible sleeved tube is connected between the spray head and the inner wall of the input cavity. The flexible sleeved tube plays an anti-rust protection role for the sleeved spring, and the sleeved spring is located inside the flexible sleeved tube. The unfolded stirring group squeezes the spray head back into the input cavity to block the spray outlet of the spray head.

[0014] Among them, the stirring group includes a lower stirring paddle. The lower end of the lower stirring paddle is connected to the stirring column by a pin shaft. The lower stirring paddle is connected to the upper stirring paddle by a pin shaft. The upper end of the upper stirring paddle is connected to the sleeved ring by a pin shaft. After the rotating plate and the sleeved ring descend, the angle between the lower stirring paddle and the upper stirring paddle is adjusted. After the angle adjustment is completed, the connection position between the lower stirring paddle and the upper stirring paddle is snapped into the insertion groove. After that, when the stirring group rotates circumferentially, the mixing paddles rotate synchronously.

[0015] Among them, the mixing paddles are made of rubber material. Insertion grooves are formed between adjacent mixing paddles. The connection part between the lower stirring paddle and the upper stirring paddle is bent and inserted into the insertion groove.

[0016] Among them, the conveying device includes a conveying pump. The conveying pump is installed on the cylinder body through a base. The conveying pump is communicated with a connecting pipe. The suction port of the connecting pipe is inserted into a reserve frame installed on the outer wall of the cylinder body. The spray outlet of the connecting pipe extends into the upper end of the input cavity, and the spray outlet of the connecting pipe is in sealed rotational fit with the input cavity. Fill the reserve frame with additives, and pump out the additives through the conveying pump and spray them out from the spray head to inject them into the material waste paper pulp fibers.

[0017] In addition, the present invention also provides a method for using a fiberboard raw material mixing device, which includes the following steps;

[0018] S1. Check the equipment parts and fill the conveying device with additives;

[0019] S2. Input the material waste paper pulp fibers from the feed port into the cylinder body. After the input is completed, drive the sealing ring to descend through the connecting cylinder. The rotating plate and the sleeved ring that descend synchronously drive the stirring group to expand and deform outward and are clamped between the insertion plates. At this time, the deep spray head extends out of the input cavity;

[0020] S3. Drive the expanded stirring group and the mixing paddles to rotate synchronously through the rotation of the stirring column. At the same time, spray the additives from the deep spray head through the conveying device and inject them into the material waste paper pulp fibers to carry out mixing and stirring;

[0021] S4. After mixing evenly, drive the sealing ring to rise through the connecting cylinder to reset the rotating plate, the sleeved ring, the stirring group, and the deep spray head. The mixed raw materials are output from the discharge port.

[0022] (III) Beneficial effects

[0023] 1. For a fiberboard raw material mixing device and its usage method according to the present invention, the deep nozzles are distributed from top to bottom on the stirring column, so that the additives are injected into the material waste paper pulp fibers more evenly, ensuring the uniformity during the initial injection. And when not stirring, the deep nozzles are pushed back into the input cavity by the extrusion of the stirring group and the ejection holes of the deep nozzles are temporarily blocked. Moreover, through the unfolded stirring group, stirring outer ring and stirring plates, the mixing area is expanded and multi-point stirring is carried out, which speeds up the stirring efficiency.

[0024] 2. For a fiberboard raw material mixing device and its usage method according to the present invention, the stirring group, stirring plates and stirring outer ring cooperate with each other to mix and stir the material waste paper pulp fibers and additives in the cylinder body. With large-area and multi-point stirring, and combined with the uniform distribution of the deep nozzles, it ensures the rapid fusion between the additives and the material waste paper pulp fibers and improves the stirring uniformity.

[0031] The embodiments of the present invention will be described below with reference to the drawings. During this process, to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0032] In addition, the terms used below are defined based on the functions in the present invention and may be different according to the intentions or conventions of users and operators. Therefore, these terms are defined based on the entire content of this specification.

[0033] As Figures 1 to 5As shown in the figure, a fiberboard raw material mixing device includes a mixing cylinder 1, a stirring device 2, a stirring outer ring 3, and a conveying device 4. A stirring device 2 is installed in the middle of the mixing cylinder 1. The inner wall of the mixing cylinder 1 is rotationally and cooperatively connected with a stirring outer ring 3. A conveying device 4 is connected between the upper end of the stirring device 2 and the outer wall of the mixing cylinder 1.

[0034] The mixing cylinder 1 includes a cylinder body 11. A bracket 12 is installed at the bottom of the cylinder body 11. A feed inlet 13 is provided at the upper end of the side wall of the cylinder body 11. A closable discharge port 14 is provided at the lower end of the side wall of the cylinder body 11.

[0035] The stirring device 2 includes a stirring column 21. The upper and lower ends of the horizontally rotating stirring column 21 are rotationally and sealingly cooperatively connected with the cylinder body 11. An input cavity 22 is provided inside the stirring column 21. A deep spray head 23 that can move in and out and reset is provided in the input cavity 22. Before the stirring group 24 is unfolded, the deep spray head 23 is squeezed into the input cavity 22 to temporarily block and seal the position of its spray outlet. Deformable stirring groups 24 are provided at the left and right ends of the stirring column 21. The lower end of the stirring group 24 is pin-connected to the stirring column 21. The upper end of the stirring group 24 is pin-connected to a sleeved ring 25. The sleeved ring 25 is sleeved on the stirring column 21 up and down. The sealing ring 27 and the descending rotating plate 26 temporarily cut off the feed inlet 13, and the synchronously descending sleeved ring 25 drives the stirring group 24 to unfold and deform. The sleeved ring 25 is installed at the lower end of the rotating plate 26. The rotating plate 26 is horizontally rotatably arranged on the sealing ring 27. A connecting cylinder 28 is connected between the sealing ring 27 and the upper end of the cylinder body 11. The connection relationship between the connecting cylinder 28, the sealing ring 27, the rotating plate 26 and the stirring column 21 ensures the lifting and lowering of the sealing ring 27. The rotating plate 26 can not only follow the lifting and lowering of the sealing ring 27 but also follow the horizontal rotation of the stirring group 24, while ensuring the horizontal rotation of the stirring column 21. A connecting ring 29 located below the stirring group 24 is installed on the stirring column 21. Stirring plates 30 are evenly installed on the connecting ring 29 along its circumference.

[0036] When using the above technical solution in specific work, the connecting cylinder 28 drives the sealing ring 27 to descend. The synchronously descending rotating plate 26 and sleeved ring 25 drive the stirring group 24 to unfold and deform outward, so that the stirring group 24 is lapped with the stirring outer ring 3. Then, as the stirring column 21 rotates, the unfolded stirring group 24 and the mixing paddle 33 rotate and stir, and the additive in the storage frame 43 is sprayed out from the protruding deep spray head 23 and injected into the material waste paper pulp fiber for mixing and stirring.

[0037] An annular rack 5 is installed at the upper end of the stirring column 21. The annular rack 5 meshes with a gear 6. The gear 6 is installed on the output shaft of a motor 7. The motor 7 is installed inside the cylinder body 11 through a motor base. By driving the gear 6 to rotate with the motor 7, the stirring column 21 is driven to rotate under the meshing cooperation of the gear 6 and the annular rack 5. The upper and lower ends of the input cavity 22 are of an open structure. The lower end of the input cavity 22 is blocked by a sealing plate 301. When the input cavity 22 contains additive residual liquid, the sealing plate 301 can be opened to discharge the residual liquid, and the input cavity 22 can be flushed from bottom to top.

[0038] The described deep spray head 23 includes a spray head 231. The spray head 231 is horizontally slidably arranged on the stirring column 21 and is communicated with the input cavity 22. A sleeve spring 232 is connected between the spray head 231 and the inner wall of the input cavity 22. The sleeve spring 232 plays a role in resetting and always keeps a tendency to extend outward from the spray head 231. A flexible sleeve pipe 233 is connected between the spray head 231 and the inner wall of the input cavity 22. The flexible sleeve pipe 233 plays an anti-rust protection role for the sleeve spring 232, and the sleeve spring 232 is located inside the flexible sleeve pipe 233. The unfolded stirring group 24 squeezes the spray head 231 back into the input cavity 22, thereby blocking the spray outlet of the spray head 231.

[0039] The described stirring group 24 includes a lower stirring paddle 241. The lower end of the lower stirring paddle 241 is connected to the stirring column 21 by a pin shaft. The lower stirring paddle 241 is connected to an upper stirring paddle 242 by a pin shaft. The upper end of the upper stirring paddle 242 is connected to a sleeve ring 25 by a pin shaft. After the rotating plate 26 and the sleeve ring 25 descend, the angle between the lower stirring paddle 241 and the upper stirring paddle 242 is adjusted. After the angle adjustment is completed, the connection position between the lower stirring paddle 241 and the upper stirring paddle 242 is snapped into the insertion groove. Then, when the stirring group 24 rotates circumferentially, the mixing paddle 33 rotates synchronously.

[0040] When using the above technical solution in specific work, after the rotating plate 26 and the sleeve ring 25 descend, the angle between the lower stirring paddle 241 and the upper stirring paddle 242 is adjusted. After the angle adjustment is completed, the connection position between the lower stirring paddle 241 and the upper stirring paddle 242 is snapped into the insertion groove, so that the stirring group 24 is lapped with the stirring outer ring 3. At the same time, the spray head 231 extends out under the action of the sleeve spring 232, and the stirring group 24 does not block it. At this time, it is in an open state. As the stirring column 21 rotates, the lapped stirring group 24 and the mixing paddle 33 rotate and stir, and the additive in the storage frame 43 is sprayed out from the extended deep spray head 23 and injected into the material waste paper pulp fiber for mixing and stirring.

[0041] The described stirring outer ring 3 includes a rotating ring 31. The rotating ring 31 is connected to the cylinder body 11 in a rotational fit manner. Insertion plates 32 are evenly installed along the circumference in the middle of the rotating ring 31. Mixing paddles 33 are evenly installed along the circumference at the upper and lower ends of the rotating ring 31. The mixing paddles 33 are made of rubber material. Insertion grooves are formed between adjacent mixing paddles 33. The connection part between the lower stirring paddle 241 and the upper stirring paddle 242 is bent and inserted into the insertion groove.

[0042] The described conveying device 4 includes a conveying pump 41. The conveying pump 41 is installed on the cylinder body 11 through a base. The conveying pump 41 is connected and communicated with a connecting pipe 42. The suction port of the connecting pipe 42 is inserted into a reserve frame 43 installed on the outer wall of the cylinder body 11. The spray outlet of the connecting pipe 42 extends into the upper end of the input cavity 22, and the spray outlet of the connecting pipe 42 and the input cavity 22 are in a sealed rotational fit.

[0043] When using the above technical solution in specific work, fill the reserve frame 43 with additives, and pump out the additives through the conveying pump 41 and spray them out from the spray head 231 so as to inject them into the material waste paper pulp fibers.

[0044] In addition, the present invention also provides a method for using a fiberboard raw material mixing device, which includes the following steps;

[0045] S1. Check the equipment parts and fill the conveying device 4 with additives;

[0046] S2. Input the material waste paper pulp fibers from the feed port 13 into the cylinder body 11. After the input is completed, drive the sealing ring 27 to descend through the connecting cylinder 28. The rotating plate 26 and the sleeved ring 25 that descend synchronously drive the stirring group 24 to expand and deform outward and are clamped between the insertion plates 32. At this time, the deep spray head 23 extends out of the input cavity 22;

[0047] S3. Drive the expanded stirring group 24 and the mixing paddles 33 to rotate synchronously through the rotation of the stirring column 21. At the same time, spray the additives from the deep spray head 23 into the material waste paper pulp fibers through the conveying device 4, so as to perform mixing and stirring;

[0048] S4. After mixing evenly, drive the sealing ring 27 to rise through the connecting cylinder 28, so that the rotating plate 26, the sleeved ring 25, the stirring group 24, and the deep spray head 23 are reset, and the mixed raw materials are output from the discharge port 14.
