Description
Technical Field
The utility model relates to the technical field of non-woven fabric production equipment, in particular to a uniform-speed air supply device.
Background
When the non-woven fabric is produced, raw materials are required to be melted and extruded, the raw materials are subjected to dosage by a metering pump, then spinning, lapping and hot rolling are performed, and finally cutting and rolling are performed. When the non-woven fabric is subjected to a hot rolling process, an air suction device is arranged below the net forming machine, an air supply device is arranged above the net forming machine, fibers are firmly adsorbed on a net curtain by the air suction device, air is directly supplied to the net forming machine by the air supply device, and when the air supply device works, the phenomenon of uneven distribution exists, so that fiber tows on the net forming machine are unevenly dispersed, and finally formed net is uneven, so that the structural strength of the net laying is low, and the quality of non-woven fabric products is affected.
Disclosure of utility model
Aiming at the defects existing in the prior art, the utility model aims to provide the uniform-speed air supply device which can enable the spinning fiber to form a net more uniformly, and has higher structural strength and higher working quality.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a uniform velocity air supply device, includes the air supply device body, this internal at least division board that is equipped with of air supply device, the division board separates into two wind channels with this internal division of air supply device, the import in wind channel is located the right side of air supply device body, and its export is located the upper end of air supply device body, be equipped with the air supply mouth on the one end that the division board is close the export, two adjacent wind channels of air supply mouth intercommunication.
The utility model is further provided with: the air channels are bent upwards from the inlet to the outlet, two partition plates are arranged to divide the air supply device body into three air channels, and the lengths of the air channels are in a decreasing state.
The utility model is further provided with: both sides of the end part of the partition plate are provided with folded plates, and the folded plates are fixed on the inner wall of the air supply device body.
Through adopting above-mentioned technical scheme, set up a plurality of wind channels, and have a plurality of import, make wind energy carry out evenly distributed in import department, also set up a plurality ofly in the export, make the wind of export also evenly distributed, add the structure of air supply mouth simultaneously, make the wind energy in the wind channel complement wind mutually, reduce the dead angle in the wind channel, make the wind current can be more even.

FIG. 1 is a cross-sectional view of the present utility model;
FIG. 2 is a schematic diagram of the structure of the present utility model.
1. An air supply device body; 2. a partition plate; 20. air supplementing port; 21. a folded plate; 3. an air duct; 30. an inlet; 31. and an outlet.
Detailed Description
Embodiments of the present utility model will be further described with reference to fig. 1 to 2.
The utility model provides a uniform velocity air supply device, includes air supply device body 1, is equipped with at least one division board 2 in the air supply device body 1, division board 2 separates into two wind channels 3 with air supply device body 1, the import 30 in wind channel 3 is located air supply device body 1's right side, and its export 31 is located air supply device body 1's upper end, division board 2 is equipped with air supply mouth 20 near on the one end of export 31, air supply mouth 20 intercommunication two adjacent wind channels 3. The air duct 3 is arranged in an upward bending way from the inlet 30 to the outlet 31, two partition plates 2 are arranged to divide the interior of the air supply device body 1 into three air ducts 3, and the lengths of the air ducts 3 are arranged in a descending state. Both sides of the end part of the partition plate 2 are provided with folded plates 21, and the folded plates 21 are fixed on the inner wall of the air supply device body 1.
Through the setting of division board 2, set up a plurality of wind channels 3, form a plurality of import 30 and export 31, wind just can evenly distribute at the import 30 department of wind channel 3, when moving to export 31 through wind channel 3, also can be even with the wind flow delivery, promote the homogeneity of sending the branch. Meanwhile, the structure of the air supply port 20 is additionally arranged, so that air flows in adjacent air channels 3 can be supplied, dead angles in the air channels 3 are reduced, and the air flows in the separated air channels 3 can be more uniform. Thereby also can be more even to the blowing off of spacing pencil, promote the structural strength of lapping.
The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
