Description

Technical Field

[0001] The utility model relates to an air duct uniform wind cleaning mechanism for a web laying machine, and relates to the technical field of nonwoven fabric production equipment, in particular to an air duct uniform wind cleaning mechanism for a web laying machine. Background Art

[0002] The web laying machine is an important equipment in the spunbond nonwoven production line. The air duct of the web laying machine generates negative pressure, which absorbs the scattered fibers onto the web curtain of the web laying machine. Due to the weaving problem of the web curtain, some flying catkins or broken fibers enter the air duct with the suction of the web laying machine, blocking the suction port, affecting the suction effect and reducing the quality of fiber web laying. Therefore, the staff needs to regularly clean the accumulated flying catkins or broken fibers in the air duct.

[0003] At present, two methods are usually used to solve the above problems. One is to adjust the structure of the net laying machine to make the net curtain loose, and the staff will drill into the air duct and use long tools to clean it, which requires stopping the machine for processing, which not only reduces efficiency but also increases the workload of on-site staff; the other is to install a pull-out channel at the upper air duct outlet, and then pull it out for cleaning. If the machine is not stopped for cleaning, flying catkins or broken fibers will still enter the air duct during cleaning, and the air suction port will still be blocked, and the first method must be used for cleaning. If the machine is stopped for cleaning, on-site staff do not need to enter the air duct, which can effectively reduce the workload, but still reduce efficiency.

[0004] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a new type of air duct uniform air cleaning mechanism for a web laying machine to overcome the problems existing in the prior art. Summary of the invention

[0005] According to the above-mentioned technical problems of low efficiency and high labor intensity of manual cleaning proposed in the prior art; the installation of a pull-out channel at the air duct opening will cause flying catkins or broken fibers to enter the air duct and block the air suction port during non-stop cleaning, and a net-laying machine air duct wind-evening cleaning mechanism is provided. The utility model mainly sets an upper and lower two-layer drawer-type cleaning mechanism that can be alternately pulled out and cleaned on the upper part of the air suction port, and air permeable plates are provided in both layers. Through the coordinated use of the two layers of air permeable plates, the wind is evenly evened, so that the fibers can be stably adsorbed on the net curtain of the net-laying machine, and at the same time, it is convenient to clean the flying catkins or broken fibers in the air duct, reducing labor costs and improving work efficiency.

[0006] The technical means adopted by the utility model are as follows:

[0007] A wind duct cleaning mechanism for a web laying machine comprises:

[0008] Furthermore, the overall frame is a barrel-shaped structure that is open at the top and bottom, and the bottom is connected to the negative pressure suction system of the web laying machine;

[0009] Further, a lattice plate is provided on the top of the overall frame;

[0010] Furthermore, a drawer structure with blocking and ventilation functions is arranged in the middle of the overall frame.

[0011] Furthermore, the overall frame is a rectangular barrel structure made of steel plates.

[0012] Furthermore, a plurality of support frames are arranged at the upper end of the outer side wall of the overall frame.

[0013] Furthermore, the drawer structure is arranged in two layers in the overall frame.

[0014] Further, the drawer structure includes: a support beam and a pull-out device A and a pull-out device B;

[0015] Furthermore, the support beams are symmetrically mounted on the inner walls on both sides of the overall frame, and are used to build a pulling channel for the pulling device A and the pulling device B, so that the pulling device A and the pulling device B can be pulled flexibly in the overall frame;

[0016] Furthermore, the pull-out device A and the pull-out device B have the same structure and size;

[0017] Furthermore, both the drawer device A and the drawer device B are open at the top and have a breathable structure at the bottom;

[0018] Furthermore, the breathable structure is a structure of a breathable plate or a breathable net.

[0019] Furthermore, the air permeable structures at the bottom of the pull-out device A and the pull-out device B have different opening rates.

[0020] Furthermore, the specifications and quantity of the pull-out device A and the pull-out device B on each layer can be set as needed, but it is necessary to ensure that the specifications and quantity of the pull-out device A and the pull-out device B are the same and correspond to each other from top to bottom.

[0021] The working process of the utility model is:

[0022] After the net laying machine has been working normally for a period of time, there is no need to stop the machine. Pull out the pulling device A and clean it. During the cleaning process, the flying catkins or broken fibers will fall into the pulling device B. After the pulling device A is cleaned and pushed back to its original position, pull out the pulling device B and clean it. After cleaning the pulling device B, return it to its original position.

[0023] Such a structure can effectively prevent flying catkins or broken fibers from falling into the air duct. The air permeable plates at the bottom of the pull-out device A and the pull-out device B have different opening rates, which can affect the air intake and thus play a role in air uniformity.

[0024] Compared with the prior art, the utility model has the following advantages:

[0025] 1. The air duct cleaning mechanism of the web laying machine provided by the utility model can realize alternating cleaning by setting a double-layer pulling device, effectively preventing flying catkins or broken fibers from falling into the air duct;

[0026] 2. The utility model provides an air duct air-balancing cleaning mechanism for the web laying machine. The air-permeable plates at the bottom of the pull-out device A and the pull-out device B have different opening rates, which can affect the air intake and thus play a role in air balancing.

[0027] In summary, the technical solution of the utility model solves the problems of low efficiency and high labor intensity of manual shutdown cleaning in the prior art; a pull-out channel is installed at the air duct opening, and flying catkins or broken fibers still enter the air duct and block the air suction port during non-stop cleaning.
