Description

Technical Field

[0001] This invention belongs to the technical field of supporting equipment for the production of nonwoven products, and specifically relates to a pulp board defiberization device. Background Technology

[0002] Twin-spun nonwovens is a relatively new nonwoven product manufacturing process. It involves using a relatively stiff fluff pulp board roll as raw material, which is directly spun onto a forming screen using a combination of meltblown technology to create a nonwoven product. Before forming the nonwoven product, the pulp needs to be opened into discontinuous single fibers, and other raw materials such as other functional fibers and / or superabsorbent polymers (SAP) are added to give it unique and excellent performance characteristics and product diversity. Typically, the single-fiber bundles of fluff pulp account for 5-95% (most commonly around 70%) of the mass percentage in nonwoven products. The aforementioned process of opening the fluff pulp board roll is the pulp unwinding process.

[0003] Technical information related to pulp board defibering devices can be found in publicly available Chinese patent documents, such as CN2512253Y (wood pulp board defibering machine), CN113151976A (a novel twin-spun nonwoven fabric production equipment and its process method), CN205954392U (a defibering device), CN101978107A (fiber nonwoven structure with improved physical properties and its preparation method), and CN245550840U (a fiber defibering machine), etc. A typical example is the "defiber body and its defibering machine" recommended by CN101107544B. Because this patent uses a set of disc-shaped blades, each with a cutter head, to perform defibering, the overall structure of the machine is relatively complex, the defibering efficiency is low, the many blades are not only difficult to install, but also have a very limited service life, leading to troublesome replacement and high daily maintenance and operating costs.

The transmission chain tensioning adjustment device 78 is located on the left side of the aforementioned left wall plate 1 at a position corresponding to the position between the gearbox shaft sprocket 71 and the left shaft head sprocket 73 of the lower front clamping roller of the pulp board.

[0035] When the pulp board clamping roller drive motor 61 of the pulp board clamping roller power drive mechanism 6 operates, it drives the pulp board clamping roller drive reduction gearbox 62. The reduction gearbox shaft 621 drives the reduction gearbox sprocket 71, which in turn drives the transmission chain 76. The transmission chain 76 simultaneously drives the left shaft head sprockets 72 and 73 of the front upper and lower clamping rollers, the left shaft head sprockets 74 and 75 of the rear upper and lower clamping rollers, the transmission chain tensioning sprocket 77, and the tensioning adjustment sprocket 784 of the transmission chain tensioning adjustment device 78 (mentioned below). During the aforementioned transmission process, the front upper and lower clamping rollers 3b and 3c and the rear upper and lower clamping rollers 3d and 3e are shown in the diagram.

During the rotation, the pulp board 100 (introduced by the pulp board guide roller 3a) is rotated in the direction shown by the arrow. Figure 4 (See diagram) The pulp board 100 is guided towards the defiberizing roller 4 so that the defiberizing roller 4 can break down the pulp board 100 into fibers, which are then led out from the aforementioned fiber extraction chamber 70 to below the upper air inlet 20 (also known as the "upper air inlet channel"), and finally out from the fiber extraction outlet 60. During the process of the defiberizing roller 4, driven by the defiberizing roller drive mechanism 30, breaking down the introduced pulp board 100, the aforementioned upper and lower air inlet devices 201 and 901 simultaneously introduce air.

[0038] When the tension of the aforementioned transmission chain 76 needs to be adjusted, the tension adjusting sprocket actuation cylinder 781 operates, causing the cylinder pin 7811 to move downwards, i.e., into the cylinder body. This moves the tension adjusting sprocket actuation cylinder 782, along with the tension adjusting sprocket shaft 783, the tension adjusting sprocket 784, and the actuation cylinder slider 785, downwards. Specifically, the actuation cylinder slider 785 moves downwards along the slider guide rail 786, thereby causing the tensioning sprocket 784 to tension the transmission chain 76 (by...). Figure 1 As shown in the figure), and vice versa, so I will not repeat the explanation.

[0043] Since the structures and working principles of the aforementioned left and right pivot drive mechanisms 40 and 50 of the pulp board rear clamping roller frame are exactly the same, and the two work synchronously and to the same extent, the applicant will only explain the operation process and the effect of the former, namely the left pivot drive mechanism 40 of the pulp board rear clamping roller frame, below.

[0044] When by Figure 4When the pulp board 100 shown has a high basis weight or multiple layers are simultaneously introduced through the pulp board inlet roller 3a, the aforementioned first and second roller gaps 3i and 3j need to be increased accordingly. Therefore, the online operator first loosens or even removes the aforementioned left screw seat screw 5121, then activates the roller shaft left pivot support plate actuation cylinder 401. The roller shaft left pivot support plate actuation cylinder column 4011 extends backward and outward, pushing the roller shaft left pivot support plate actuation cylinder column connector 402, which in turn drives the roller shaft left pivot support plate actuation cylinder column connector hinge shaft 403, thereby hinged by the roller shaft left pivot support plate actuation cylinder column connector. Shaft 403 rotates a certain angle via the left pivot support plate 51 of the roller shaft, with the shaft head 511 of the left pivot support plate as the rotation center. Simultaneously, this causes the pulp board rear clamping roller frame 5 to tilt backward by a certain angle. At this time, as the upper and lower clamping rollers 3d and 3e of the pulp board tilt backward with the rear clamping roller frame 5, they also tilt backward by a certain angle. The aforementioned first and second roller gaps 3i and 3j increase to accommodate the basis weight or thickness of the pulp board 100. After adjustment, the aforementioned left screw seat screw 5121 is returned, i.e., screwed onto the left screw seat locking block 12. Since the adjustment process is essentially the opposite of the aforementioned process, the applicant will not repeat it here.

The left end of the abutment plate adjusting block 84 extends to the left side of the left wall plate 1 through a cavity opened in the left wall plate 1 and forms a left adjusting screw connecting seat 842. A left adjusting screw 8421 is provided on the left adjusting screw connecting seat 842. The upper end of the left adjusting screw 8421 is rotatably supported on the left adjusting screw seat 13 fixed to the left side of the left wall plate 1. The right end of the abutment plate adjusting block 84 extends to the right side of the right wall plate 2 through a cavity opened in the right wall plate 2 and forms a right adjusting screw connecting seat 843. A right adjusting screw 8431 is provided on the right adjusting screw connecting seat 843.The upper end of the right adjusting screw 8431 is rotatably supported on the right adjusting screw seat 23, which is fixed to the right side of the right wall panel 2.

[0046] Preferably, a left adjusting screw connector limiting guide block 14 is fixed on the left side of the aforementioned left wall panel 1 and at a position corresponding to the front of the aforementioned left adjusting screw connector 842, and a right adjusting screw connector limiting guide block 24 is fixed on the right side of the aforementioned right wall panel 2 and at a position corresponding to the front of the right adjusting screw connector 843. The front side of the left adjusting screw connector 842 is in contact with the rear side of the left adjusting screw connector limiting guide block 14, and the front side of the right adjusting screw connector 843 is in contact with the rear side of the right adjusting screw connector limiting guide block 24.

[0047] In this embodiment, the aforementioned pulp board abutment plate 83 is preferably made of nylon material, and can be replaced as needed when it becomes severely worn over time and no longer usable through adjustment. Figure 4 As can be seen from the diagram, in the usage state, the pulp board front limit plate contact slope 814 and pulp board contact surface 831 at the bottom of the pulp board abutment plate adjusting block front limit plate 81 in the length direction are in contact with the pulp board 100. To accommodate the thickness of the pulp board 100, the front limit plate 81 of the pulp board abutment plate adjusting block is adjustable up and down. Taking downward adjustment as an example, first unscrew the locking block fixing screw 8133 from the connecting beam 10b behind the wall panel, and loosen the locking block locking screw 8132, that is, release the threaded connection between the locking block locking screw 8132 and the bottom wall of the locking block cavity 812. At the same time, loosen the front limit plate up and down adjusting screw 8111, and then turn the locking block adjusting screw 8131 downward. At this time, the front limit plate 81 of the pulp board abutment plate adjusting block moves downward so that the front limit plate of the pulp board contacts the inclined surface 814 and contacts the pulp board 100. After the adjustment is completed, tighten the aforementioned locking block fixing screw 8133 and the front limit plate up and down adjusting screw 8111, and lock the locking block locking screw 8132 (connected to the threaded hole on the bottom wall of the locking block cavity 812). Since the process of adjusting the front limit plate 81 of the pulp board abutment plate adjusting block upwards can be fully understood through the aforementioned description of downward adjustment, the applicant will not elaborate further.

[0048] When the aforementioned pulp board abutment plate 83 needs to be adjusted downward, simply rotate the aforementioned left and right adjusting screws 8421 and 8431. The abutment plate adjusting block 84 will drive the pulp board abutment plate 83 to move downward, so that the pulp board contact surface 831 is in contact with the pulp board 100, and vice versa.

[0049] Depend on Figure 4As shown, the pulp board 100 sequentially passes through the pulp board inlet roller 3a, the rear surface of the pulp board transition guide plate 3f, the first roller gap 3i, the rear surface of the pulp board intermediate transition guide plate 3g, the second roller gap 3j, the rear surface of the pulp board lower transition guide plate 3h, the area between the front and rear upper windshields 80a and 80c of the defiberizing roller, the pulp board front limiting plate contact slope 814, and the pulp board contact surface 831 below the pulp board abutment plate 83 in the length direction. When the pulp board 100 reaches the area in the length direction of the defiberizing roller 4, it is disintegrated by the defiberizing needle cloth 41 to form fibers 1001, which are then separated from the aforementioned... Figure 4 The fiber shredding exit chamber 70 shown is able to exit because, when the upper air inlet device 201 delivers a certain pressure to the upper air inlet 20, the fiber 1001 entering the upper air inlet duct of the upper air inlet 20 is drawn out from the fiber shredding exit 60 at the lower part of the upper air inlet duct. During the aforementioned process, the lower air inlet 90 is simultaneously introduced with a certain pressure by the lower air inlet device 901 to ensure that the fiber is concentrated in the direction of the aforementioned fiber shredding exit chamber 70. Furthermore, as described above, when the defiberizing roller 4 is in motion, the aforementioned pulp board traction roller power drive mechanism 6, pulp board traction roller transmission mechanism 7, and defiberizing roller drive mechanism 30 are all in working condition.

[0050] In summary, the technical solution provided by this invention makes up for the shortcomings of the prior art, successfully completes the invention task, and accurately realizes the technical effects described by the applicant in the above technical effects column.
