[0002] Cellulose meltblown fabric is a type of nonwoven fabric made from cellulose raw materials through a meltblowing process. The raw materials used for cellulose meltblown fabric are generally natural substances with a high cellulose content, such as wood pulp and short-staple cotton. These raw materials are crushed, dissolved, and pulped to produce the spinning solution used for meltblowing.

[0003] Since wood pulp cotton and short-staple cotton contain a certain amount of moisture, they need to be dried before processing to reduce the impact of moisture on subsequent processes. Existing cellulose meltblown cloth raw material drying devices are generally drum dryers, which drive the raw materials to be blown by a hot air blower, and then drive the raw materials to be continuously rolled for drying. However, when drying in this way, the dried raw materials will continue to mix with the undried raw materials until they can be discharged at the end, making it inconvenient to separate the dried raw materials in time. The drying degree of the raw materials is not uniform, and the raw materials have a certain amount of moisture and are easy to clump, which is not convenient to tear apart the clumped raw materials.

After starting work, the staff starts the hot air blower 4 and the servo motor 101. The hot air blower 4 draws in air and heats the air, and then blows the heated air into the drying cylinder 3. The output shaft of the servo motor 101 rotates to drive the gear one 102 to rotate. Gear 1 102 drives gear 2 103 to rotate through toothed belt 104, and gear 2 103 rotates to drive drying drum 3 to rotate, and the rotation of drying drum 3 drives screening net 5, rotating shaft 105, torsion spring 106 and arc plate 112 to rotate together, and rotating shaft 105 rotates to drive gear 3 108 to rotate, and arc plate 112 rotates to cover the air outlet pipe of hot air blower 4, and the communicating port of arc plate 112 and the air inlet of drying drum 3 are no longer connected with the air outlet pipe of hot air blower 4, reducing the fluff and debris of raw materials entering hot air blower 4 during unloading. After arc plate 112 covers the air outlet pipe of hot air blower 4, gear 3 108 continues to rotate and meshes with arc rack 109. Under the action of arc rack 109, gear 3 108 will rotate by itself, and the rotation of gear 3 108 drives gear 3 108 to rotate by itself. The shaft 105 rotates, the torsion spring 106 is twisted, and the rotation of the shaft 105 drives the limit plate 107 to rotate. The rotation of the limit plate 107 no longer covers the discharge port of the discharge hose 7. Under the action of gravity, the raw materials in the discharge hose 7 will fall into the drying cylinder 3, and the curved plate 112 continues to rotate to drive the air inlet of the air pipe 113 to be aligned with the air outlet pipe of the hot air blower 4.

The arc plate 112 rotates in the opposite direction to drive the air inlet of the air pipe 113 to rotate in the opposite direction. The air inlet of the air pipe 113 is no longer aligned with the air outlet pipe of the hot air blower 4. The connecting port of the arc plate 112 and the air inlet of the drying drum 3 are connected with the air outlet pipe of the hot air blower 4 again, so that the hot air flow re-enters the drying drum 3. The drying drum 3 continues to rotate in the opposite direction to drive the raw material to roll along the bottom of the inner wall of the drying drum 3, and the hot air flow has an impact on the raw material. The dried raw materials will be blown away by the hot air flow during the rolling process and move in the direction of the hot air flow, eventually passing through the screening mesh 5 and leaving the drying drum 3. The undried raw materials will remain in the drying drum 3 and continue to roll and dry. After the dried raw materials leave the drying drum 3, they will be blocked by the material blocking plate 125. The exhaust gas will pass through the material blocking plate 125 and enter the exhaust gas treatment system through the exhaust pipe 8 for filtration. During the rotation of the drying drum 3, the fixed brush 6 will continue to brush the screening mesh 5 to reduce the chance of the raw materials blocking the screening mesh 5. Then the staff will adjust the servo motor 101 to rotate back and forth, and repeat the above operation.

[0043] During the drying process, the rotation of the drying drum 3 drives the gear 4 121 to rotate, the rotation of the gear 4 121 drives the gear 5 123 to rotate, the rotation of the gear 5 123 drives the rotating shaft 2 122 to rotate, the rotation of the rotating shaft 2 122 drives the slotted frame 124 to rotate, the rotation of the slotted frame 124 drives the contact roller 128 to move downward, the downward movement of the contact roller 128 drives the connecting frame 127 to move downward, the downward movement of the connecting frame 127 drives the scraper frame 126 to move downward, the scraper frame 126 moves downward to scrape the dried raw materials on the blocking plate 125, the drying drum 3 rotates in the opposite direction to drive the gear 4 121 to rotate in the opposite direction, the reverse rotation of the gear 4 121 drives the gear 5 123 to rotate in the opposite direction, the reverse rotation of the gear 5 123 drives The movable rotating shaft 122 rotates in the opposite direction, and the opposite rotation of the rotating shaft 122 drives the slotted frame 124 to rotate in the opposite direction.

The scraped raw materials will accumulate at the bottom of the inner wall of the box 1. After the drying work is completed, the staff turns off the hot air blower 4 and the servo motor 101, opens the closed door 9, exposes the discharge port of the box 1, takes away the dried raw materials, cleans the fixed brush 6, and then closes the closed door 9 to facilitate the next work.

The two contact shafts 135 on the same sliding frame 131 contact the convex disc 136 on the same side. The convex disc 136 squeezes the contact shaft 135 through the protrusions, thereby driving the mace 132 to move through the sliding frame 131.

[0046] Initially, the two contact shafts 135 on the same sliding frame 131 are in contact with one of the two convex discs 136. The protective sleeve 133 is used to prevent the raw materials from blocking the reset spring 134. The rotation of the drying drum 3 drives the sliding frame 131 and the protective sleeve 133 to rotate. The rotation of the sliding frame 131 drives the mace 132, the reset spring 134 and the contact shaft 135 to rotate. The protrusion on the convex disc 136 will squeeze the contact shaft 135, and the two groups of contact shafts 135 will move toward each other. The movement of the two groups of contact shafts 135 in the direction of approaching each other drives the two sliding frames 131 to move in the direction of approaching each other.
