Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a raw material screening device for non-woven fabric production. Background Art

[0002] The formation of non-woven fabrics is that thermoplastic polyurethane particles are heated, melted, and extruded into a melt through a screw extruder. When the melt is extruded from the spinneret holes of the die head, it is blown by hot air flows on both sides of the spinneret holes, and the melt is stretched into warp ultrafine fibers, forming polyurethane elastic non-woven fabrics through self-adhesion.

[0003] Chinese patent, a screening device for raw materials for non-woven fabric production, publication number: CN215695642U, by setting components such as a vibrating motor and a spring, the practical screening device can drive the screening box to vibrate continuously during screening, thereby improving the screening efficiency and reducing the screening time. By setting a plurality of screens with different apertures, the raw materials can be finely screened into a plurality of particles of different sizes and at equal distances, which is convenient for subsequent processing and production. By setting components such as a turning handle, a transfer rod, a toothed disc, a connecting rod, a transfer block, a collecting box, etc., the practical device can collect the screened raw materials of different sizes into a plurality of collecting boxes by rotating the turning handle after the screening is completed. During screening, if there are too many materials to be screened and all of them are accumulated on the top layer, the accumulation of materials will cause the screen surface of the vibrating screen to be blocked or the materials cannot be evenly distributed on the screen surface.

[0022] like Figure 1-5As shown, the utility model proposes a raw material screening device for non-woven fabric production, including a base 1, a box body 2 and a vibration motor 3, the box body 2 is arranged at the top of the base 1, the vibration motor 3 is arranged at the bottom of the box body 2, and also includes a screen plate 5, a movable frame 6, a rotating component 7 and a driving component 8. A rotating frame is provided on the left side of the box body 2, the screen plate 5 is arranged in the box body 2, the rotating component 7 is arranged in the rotating frame, and drives the screen plate 5 to rotate, the movable frames 6 are respectively arranged above the screen plate 5, the driving component 8 is arranged in the box body 2, and drives the movable frame 6 to move, and a combing strip 61 is provided at the bottom end of the movable frame 6.

[0023] In the utility model, four shock-absorbing legs are arranged on the top of the base 1, which are connected to the box body 2 through the four shock-absorbing legs. By using the vibration motor 3 to vibrate, the box body 2 is also vibrated to increase the screening efficiency. The shock-absorbing legs are used to reduce the shock. The top of the box body 2 is missing, and materials are put into the top of the box body 2 for screening. A plurality of sieve plates 5 are arranged inside the start-up box 2, and there are intervals between them. The plurality of sieve plates 5 are divided into different levels, and the smaller mesh is arranged at the bottom. By using the driving component 8 to drive the plurality of mobile frames 6 to move left and right, the mobile frame 6 drives the plurality of combing strips 61 to move back and forth, and the materials accumulated on the sieve plates 5 are evenly dispersed, so that the materials can be better dispersed and distributed on the screen surface to prevent material accumulation. By using the rotating component 7 to drive the plurality of sieve plates 5 to rotate simultaneously in one direction, and with self-locking property, after the driving is stopped, there will be no reversal due to the action of the load.

[0024] In an optional embodiment, the rotating assembly 7 includes a first motor 71, a worm 72, a first rotating rod 73, a second rotating rod 74 and a worm wheel 75. The first motor 71 is arranged at the top of the box body 2, one end of the worm 72 is coaxially connected to the output shaft of the first motor 71, and the other end is rotatably connected to the bottom wall of the rotating frame, one end of the first rotating rod 73 is connected to the left side of the screen plate 5, and the other end is rotatably connected to the left side wall of the rotating frame, one end of the second rotating rod 74 is connected to the right side of the screen plate 5, and the other end is rotatably connected to the right side wall of the box body 2, and the worm wheel 75 is sleeved on the first rotating rod 73 and meshed with the worm 72.

[0025] It should be noted that starting the first motor 71 drives the worm 72 to rotate, drives the worm wheel 75 to rotate, thereby drives the first rotating rod 73 and the second rotating rod 74 to rotate, thereby drives the screen plate 5 to rotate. Because there are multiple sieve plates 5, corresponding first rotating rods 73, second rotating rods 74 and worm wheels 75 are also provided in multiple groups. By using the first motor 71 to drive the worm 72 and then drive multiple worm wheels 75 to rotate, multiple screen plates 5 can be rotated in the same direction, and materials can be discharged in the same direction for easy collection.

[0026] In an optional embodiment, the plurality of combing strips 61 are spaced apart and are located above the second rotating rod 74 .

[0027] It should be noted that when the movable frame 6 is moved close to the right side wall of the box body 2 , the combing strips 61 do not contact the second rotating rod 74 , and will not hinder the rotation of the screen plate 5 .

[0030] It should be noted that because there are multiple sieve plates 5, there are also multiple discharge ports, and there are also multiple baffle plates 4. When screening, push the pull rod 41 to make the baffle plate 4 block the discharge port. After the screening is completed, pull the pull rod 41 to pull out the baffle plate 4. At this time, start the rotating assembly 7 to rotate the multiple sieve plates 5, so that the screened material falls into the receiving hopper 10, and the final material falls into the receiving drawer 9.

[0031] In an optional embodiment, the driving assembly 8 includes a second motor 81, a threaded rod 82, a sliding member 83 and a moving plate 84. A driving frame is provided on the rear side of the box body 2. The second motor 81 is connected to the left side of the driving frame. One end of the threaded rod 82 is coaxially connected to the output shaft of the second motor 81, and the other end is rotatably connected to the right side wall of the driving frame. The sliding member 83 is threadedly connected to the threaded rod 82 and extends into the box body 2. The moving plate 84 is located in the box body 2 and is connected to the sliding member 83. The moving frame 6 is connected to the front side of the moving plate 84.

[0032] It should be noted that by starting the second motor 81, the threaded rod 82 is driven to rotate, thereby driving the sliding member 83 to move, and the sliding member 83 drives the moving plate 84 to move. Because there are multiple screen plates 5, there are also multiple moving frames 6, and there are also multiple groups of combing strips 61.
