Description

Short fiber adsorption forming device

Technical Field

The utility model relates to a short-staple former field specifically is a short-staple adsorbs forming device.

Background

The web forming mechanism plays a role in extruding and drafting the spinneret orifices of the die head by high-speed hot air flow in a molten state, then falling on a web forming curtain or a roller, and forming and collecting superfine fibers by a cooling and drying mode. However, the existing collecting mechanism or collecting roller has insufficient hot air flow cooling and diffusion, and the heat bonding effect between fibers is strong, so that the bulkiness of the product is reduced, the volume density of the fiber web is increased, and the elongation of the product is reduced. Meanwhile, due to the lack of a deviation correcting device, a final finished product deviates and becomes waste, and the production efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a following technical scheme: a short fiber adsorption forming device comprises a bottom frame, a lifter and a motor, wherein the lifter is fixed on the bottom frame and is connected with the motor; the elevator further comprises a group of supporting walls, and the supporting walls are supported by the elevator; one side surface of the supporting wall body extends inwards to form a cuboid air suction cavity; the net curtain supporting plate is connected with the supporting wall body and abuts against the upper surface of the air suction cavity.

Preferably, the wall body further comprises a driving roller and a driven roller, the driving roller is fixed at one corner below the supporting wall body, and the driven roller is fixed at the other three corners of the supporting wall body.

The better still includes the tensioning roller and rectifies the deviation roller, the tensioning roller is fixed in directly over the drive roll, rectify the deviation roller movable mounting in support wall's base department, be close to the drive roll.

Preferably, the side edge of the deviation rectifying roller is connected with an air cylinder.

Preferably, the cloth guide device further comprises a cloth guide roller, wherein the cloth guide roller is fixed on one side, far away from the tensioning roller, of the support wall body through a support frame.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model has the advantages that the hot air generated at the upper end extrusion die head is quickly absorbed by the air suction cavity, so that the molten polypropylene falling on the web forming curtain can be quickly cooled, the heat bonding effect between fibers is reduced, and the filling power of the product is improved; meanwhile, the deviation correcting roller is arranged, so that the net curtain is always positioned in the center of the roller surface and cannot deviate.

in the figure: the device comprises a bottom frame 1, a lifter 2, a motor 3, a supporting wall 4, an air suction cavity 5, a screen supporting plate 6, a driving roller 7, a driven roller 8, a tensioning roller 9, a deviation rectifying roller 10, an air cylinder 11, a cloth guide roller 12, a supporting frame 13, a transmission motor 14, a connecting hose 15, a connecting hard pipe 16 and an induced draft fan 17.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a short fiber adsorption forming device comprises a bottom frame 1, a lifter 2 and a motor 3, wherein the lifter 2 is fixed on the bottom frame 1 and is connected with the motor 3; a set of supporting walls 4, said supporting walls 4 being supported by said elevator 2; a cuboid air suction cavity 5 extends inwards from one side surface of the supporting wall 4; the wind-absorbing device further comprises a net curtain supporting plate 6, wherein the net curtain supporting plate 6 is connected with the supporting wall 4 and abuts against the upper surface of the wind-absorbing cavity 5. The receiving distance of the melt-blown process, namely the distance from the outlet of a spinneret hole of the die head to the net forming curtain, is adjusted by rotating the motor 3 in time, the receiving distance is reduced, hot air flow is insufficiently cooled and diffused, the heat bonding effect between fibers is strong, the bulkiness of the product is reduced, the volume density of the fiber net is increased, and the elongation of the product is reduced. When receiving the distance increase, fibrous fluffiness increase, the fibre fineness when increase, product porosity grow, and filtration efficiency worsens, and the resistance diminishes, and the product elongation also can improve. The key point is that when the receiving distance is controlled, the air suction cavity 5 is also matched with the connecting hose 15 and the connecting hard pipe 16 to be connected with the induced draft fan 17 to perform net bottom air suction, otherwise, the fibers cannot be fully adsorbed on the net curtain.

The roller device is characterized by further comprising a driving roller 7 and a driven roller 8, wherein the driving roller 7 is fixed at one corner below the supporting wall 4 and is directly connected with a speed reducer matched with a transmission motor 14 to play a transmission role, so that all roller bodies rotate in the same direction to drive a net curtain. The driven rollers 8 are fixed at the other three corners of the support wall 4. Still include tensioning roller 9 and rectification roller 10, tensioning roller 9 is fixed in directly over the drive roll 7 for guarantee that the net curtain is in the tensioning state always. The deviation rectifying roller 10 is movably arranged at the bottom edge of the supporting wall 4 and close to the driving roller 7. The side edge of the deviation rectifying roller 10 is connected with an air cylinder 11, when the deviation rectifying roller generates deviation as a net curtain, the air cylinder 11 works to drive the deviation rectifying roller 10 to be pulled back and forth, and the net curtain is ensured to be always positioned at the center of the roller body.
