Technical Field
[0001] This utility model relates to the field of nonwoven fabric scrap processing technology, and more specifically to a pulping device for Lyocell nonwoven fabric scrap. Background Technology
[0002] Lyocell nonwoven fabric is a nonwoven fabric made from environmentally friendly lyocell fibers through hydroentangling, and its main component is cellulose. During the production process, excess scraps are generated. Current recycling methods often involve opening these scraps to form new fibers for reuse as raw materials for nonwoven fabrics. However, because these scraps easily form short fibers and clumps after opening, reuse leads to a decline in the quality of the nonwoven fabric. In cases involving high-strength nonwoven fabrics, opening may not even be possible, resulting in waste.
[0003] With the increasing popularity of wet-laid nonwoven fabrics, the demand for special ultra-short-cut cellulose fibers is growing. It is worth considering cutting lyocell nonwoven fabric scraps into 3-8mm short fibers, and then utilizing the fibrillary structure of lyocell fibers, after swelling with water, pulping and splitting them into micro / nanocellulose fibers, thereby increasing the recycling value of the scraps.
[0004] However, the existing pulping devices have simple impeller structures, and the mixing and dispersing effects are not ideal, making it impossible to produce short-cut fibers with ideal micro-nano structures. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pulping device for lyocell nonwoven fabric scraps, which can better disperse and mix the scraps in the mixing tank, resulting in a better mixing effect.
[0006] The solution of this utility model to the aforementioned technical problem is:
[0007] A pulping device for lyocell nonwoven fabric raw materials includes a mixing chamber. A transverse mixing shaft is provided in the mixing chamber. The left end of the transverse mixing shaft is movably connected to the left side plate of the mixing chamber via a bearing, and the right end of the transverse mixing shaft is movably connected to the right side plate of the mixing chamber via a bearing. The right end of the transverse mixing shaft extends out of the right side plate of the mixing chamber. A motor frame is fixed on the right side wall of the right side plate of the mixing chamber.

Multiple mixing wheels are fixed on the outer side wall of the transverse mixing shaft, and there is a gap between adjacent mixing wheels.
[0008] The lower part of the left side plate of the mixing tank is formed with a discharge through hole. The right end of the discharge pipe is in the discharge through hole. The outer side wall of the right end of the discharge pipe is pressed against the inner side wall of the discharge through hole and welded and fixed. A transverse plug is installed on the discharge pipe.
[0009] The bottom edge of the bottom plate of the mixing tank is fixed with a lower box extending downwards. The lower part of the lower box is fixed with a bottom support box. A middle lifting cylinder is fixed in the middle of the bottom plate of the lower box. The top of the push rod of the middle lifting cylinder extends out of the top of the middle through hole of the bottom plate of the lower box and is fixed with a lifting plate. The top surface of the lifting plate presses against the bottom surface of the bottom plate of the mixing tank. An elastic sealing layer is fixed on the side wall of the lifting plate. The outer wall of the elastic sealing layer is in close contact with the inner side wall of the corresponding side plate of the lower box.
[0010] An inner sealing layer is fixed on the inner wall of the through groove, and the lower outer wall of the plug plate is in close contact with the corresponding inner sealing layer.
[0011] The bottom surface of the lifting plate is fixed with multiple guide rods. The guide rods are inserted into guide sleeves fixed on the inner side wall of the guide through hole on the bottom plate of the lower box. The outer side wall of the guide rod is in close contact with the inner side wall of the corresponding guide sleeve.
[0012] The bottom surface of the lifting plate is fixed with multiple liquid guiding cylinders.

The lower part of the liquid guiding cylinder is inserted into the guide sleeve fixed on the inner side wall of the corresponding guide through hole on the bottom plate of the lower box, and its outer side wall is in close contact with the inner side wall of the corresponding guide sleeve.
[0013] Multiple left-right extending guide rails are fixed on the top surface of the bottom plate of the bottom support box. The receiving trough is located in the bottom support box. Multiple sliders are fixed on the bottom surface of the bottom plate of the receiving trough. The upper part of the guide rail is inserted into the lower guide groove formed in the middle of the bottom surface of the corresponding slider and cooperates with it. The receiving trough is located directly below the lifting plate.
[0014] A gripping part is fixed on the right side wall of the receiving trough, and the gripping part is inserted into the inlet and outlet passage formed on the right side plate of the bottom support box.
[0015] The outstanding effect of this utility model is:
[0016] By raising or lowering the lifting plate, the plug plate can be inserted into the mixing chamber to join the mixing, or removed from the mixing chamber, thereby increasing the space in the mixing chamber and increasing the flow range of the mixed materials.

[0034] In this embodiment, when in use, the aqueous solution of shredded non-woven fabric scraps is poured from the feed funnel 5 into the mixing box 10. The stirring motor 13 is run to make all the stirring wheels 111 rotate. The upper part of the plug plate 32 at the bottom is located at the gap between the corresponding two adjacent stirring wheels 111, participating in stirring and crushing dispersion.
[0035] After running for a certain period of time, such as 10 minutes, the push rod of the intermediate lifting cylinder 320 retracts (in this embodiment, the intermediate lifting cylinder 320 is connected to the hydraulic system via a connecting oil pipe. The hydraulic system includes an oil pump, an oil tank, and various solenoid valves. All electrical components used in this embodiment are electrically connected to the control host via electrical connection lines and are controlled by the control host. This is a conventional structure and will not be described in detail here), causing the lifting plate 31 to descend and the plug plate 32 to retract until its top surface meets the top of the through groove 16. When the surface is flat, the space in the mixing tank 10 increases. As the stirring wheel 111 rotates, the flow pattern of the aqueous solution mixed with non-woven fabric scraps changes, causing it to mix. After running for 10 minutes, the push rod of the intermediate lifting cylinder 320 pushes the plug plate 32 back into the mixing process, further altering the mixing and dispersion of the aqueous solution mixed with non-woven fabric scraps. This change makes the mixing of the aqueous solution mixed with non-woven fabric scraps more thorough and the mixing effect better.
[0036] After completion, the push rod of the intermediate lifting cylinder 320 retracts, causing the plug plate 32 to retract until its top surface is flush with the top surface of the through groove 16. Then, the transverse plug 20 is rotated so that the end of the small diameter shaft extends out of the inner end of the small diameter hole section to prevent material blockage. Then, the transverse plug 20 is rotated again so that the small diameter shaft moves to the left until the outer wall of the sealing ring 1 presses against the left end of the small diameter hole section. At this time, the material in the mixing tank 10 will flow out from the bottom of the drop pipe 17 to achieve material discharge, which is very convenient.
[0037] When in use, during the lifting process of the lifting plate 31, some liquid may flow out and drip into the receiving tank 50 along with the liquid guide cylinder 35. After the operation is completed, the receiving tank 50 can be removed so that the material inside can be poured back into the mixing tank 10 for reuse.
[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
