DETAILED DESCRIPTION

[0025] Based on this, in order to improve the problem that the dust collector on the device in the related art may generate suction force on the non-woven fabric when absorbing dust on the non-woven fabric, causing the position of the non-woven fabric on the feeding device to deviate, thereby affecting subsequent spraying and sewing operations, and finally the quality of the finished product is not up to standard, the embodiments of the present application provide the following solutions.

[0026] Please refer to Figures 1-4 , including rack 1, dust suction mechanism 3 and suction mechanism 2, the suction mechanism 2 includes conveyor belt 21, rotating motor 22, conveying roller 23, vacuum pump 24, gas pipeline 25 and vacuum chamber 26, the dust suction mechanism 3 is fixedly connected on the rack 1, the rotating motor 22 is threadedly connected on the rack 1, the conveying roller 23 is fixedly connected on the output end of the rotating motor 22, the conveyor belt 21 is drivingly connected on the conveying roller 23, the conveyor belt 21 is provided with through holes, and the conveyor belt 21 forms an oval placement cavity, the vacuum chamber 26 is arranged in the placement cavity and is fixedly connected with the rack 1, one end of the gas pipeline 25 is bonded on the vacuum pump 24, the other end of the gas pipeline 25 is bonded on the vacuum chamber 26, the vacuum chamber 26 is provided with a blind hole, and the vacuum chamber 26 is communicated with the gas pipeline 25.

[0027] In this way, during the non-woven fabric bag production feeding process, the non-woven fabric is first moved to the conveying belt 21, the conveying roller 23 is driven to rotate by the rotating motor 22, the conveying belt 21 is driven to rotate, after the vacuum pump 24 is started, the vacuum pump 24 starts to inhale, the vacuum pump 24 draws the air in the vacuum chamber 26 away through the gas pipeline 25, a negative pressure is formed in the vacuum chamber 26, and the non-woven fabric is adsorbed on the surface of the conveying belt 21 through the through hole on the conveying belt 21, so that the non-woven fabric and the conveying belt 21 remain relatively stationary. When the non-woven fabric passes through the dust suction mechanism 3, the dust and debris on the surface of the non-woven fabric are sucked away by the dust suction mechanism 3, but due to the adsorption effect caused by the negative pressure, the non-woven fabric itself is still relatively fixed with the conveying belt 21, and the relative position of the non-woven fabric and the conveying belt 21 is not changed during the dust suction process, so that the position of the non-woven fabric after leaving the conveying belt 21 is not deviated, and the subsequent operation is not affected. At the same time, the vacuum chamber 26 itself supports the conveying belt 21.

[0028] Optionally, in some embodiments, referring to Figure 3 , a plurality of cylindrical grooves are formed in the vacuum chamber 26, the direction of the blind hole formed in the vacuum chamber 26 is perpendicular to the direction of the cylindrical grooves, and the cylindrical grooves are connected to all the cylindrical grooves. A reverse trapezoidal groove is formed in the cylindrical groove, and the reverse trapezoidal groove of the vacuum chamber 26 is connected to the through hole on the conveying belt 21.

[0029] In this way, when the vacuum pump 24 starts to inhale, the air first passes through the through hole on the conveying belt 21, then passes through the reverse trapezoidal groove of the vacuum chamber 26, and then passes through the cylindrical groove. The air in the plurality of cylindrical grooves is finally gathered into the blind hole and enters the gas pipeline 25 through the blind hole, so that the non-woven fabric on the conveying belt 21 is adsorbed and kept relatively stationary. The reverse trapezoidal groove formed in the cylindrical groove is beneficial to increasing the gas flow rate and strengthening the adsorption force of the non-woven fabric.

[0030] Optionally, in some embodiments, referring to Figure 1 and Figure 2 , the dust suction mechanism 3 comprises a dust collector 31, a placing rack 32, a dust suction port 33 and an electrostatic elimination assembly 34. The placing rack 32 is welded on the rack 1, the placing rack 32 is provided with a through hole, the dust collector 31 is threadedly connected to the placing rack 32, and the air suction end of the dust collector 31 passes through the through hole. The dust suction port 33 is movably connected to the air suction end of the dust collector 31, and the electrostatic elimination assembly 34 is arranged on the rack 1.

[0031] In this way, after the non-woven fabric is kept relatively static with the conveyor belt 21, the non-woven fabric is first removed of surface static electricity by the static electricity removing assembly 34, and then the non-woven fabric is conveyed to below the placing rack 32, the dust collector 31 is started, and the dust suction port 33 performs dust suction operation on the dust and debris on the surface of the non-woven fabric. At this time, due to the suction effect of the suction mechanism 2, the non-woven fabric is relatively stable during the dust suction process.

[0032] Optionally, in some embodiments, referring to Figure 5 , the dust suction port 33 is in the shape of a flat suction port, and the edge of the suction port is smooth. The dust suction port 33 is fixedly connected with a pressure difference valve 35.

[0033] In this way, the flat suction port is conducive to forming a narrower air flow channel, thereby increasing the suction force, so that the dust collector 31 can more effectively suck the dust, debris and fine particles on the surface of the non-woven fabric. The edge of the suction port is relatively smooth to reduce scratches or damage to the cleaned surface. The pressure difference valve 35 is used to automatically open when the air pressure difference at the suction port of the dust collector 31 reaches a certain degree, allowing more air and dust to be sucked into the interior of the dust collector 31. When the air pressure difference decreases, the valve is closed to prevent backflow of dust and air.

[0034] Optionally, in some embodiments, referring to Figure 1 and Figure 2 , the static electricity removing assembly 34 includes an ion blower 341 and a humidifier 342. The rack 1 is bonded with a placing plate 5. The ion blower 341 and the humidifier 342 are bonded on the placing plate 5, and the humidifier 342 is located between the ion blower 341 and the conveyor belt 21.

[0035] In this way, the main function of the ion blower 341 is to generate positive and negative ions, which are brought to the surface of the object by the airflow blown out, thereby neutralizing the static electricity on the surface of the object. The humidifier 342 reduces the generation of static electricity by increasing the indoor humidity. Dry air is easy to make the object charged, while the humidifier 342 can increase the moisture content in the air, thereby reducing the possibility of the object being charged. The use of the ion blower 341 and the humidifier 342 together can further enhance the effect of removing static electricity. After the humidifier 342 is turned on, the ion flow blown out by the ion blower 341 drives the humidity to the surface of the non-woven fabric, so as to achieve the effect of removing static electricity, which is helpful to enhance the effect of subsequent suction of dust and debris.

[0036] Optionally, in some embodiments, referring to Figure 1 and Figure 2 , the rack 1 is also welded with a printing box 4, which is used for printing processing of the non-woven fabric.

[0037] Thus, since the conveying belt 21 has the adsorption function, the relative position between the non-woven fabric and the conveying belt 21 will not change during the dust suction process, so that the position of the non-woven fabric after leaving the conveying belt 21 will not be deviated, and thus, after the dust is cleaned, the printing box 4 can be directly installed for printing the non-woven fabric. The printing box 4 is usually equipped with a printing cylinder, an ink system and necessary transmission and control devices for printing patterns or characters on the surface of the non-woven fabric. Through accurate mechanical design and adjustment, the printing box 4 can ensure that the ink is uniformly and accurately transferred to the non-woven fabric, so as to meet various printing requirements.

[0038] Optionally, in some embodiments, referring to Figure 3 , the vacuum chamber 26 is provided with a blind hole on one side close to the conveying belt 21, and the ball 6 is rotatably connected in the blind hole, and the ball 6 abuts against the conveying belt 21.

[0039] Thus, since the vacuum chamber 26 generates negative pressure, the conveying belt 21 can be in contact with the surface of the vacuum chamber 26, which can cause large friction and damage to the conveying belt 21. In addition, the large-area contact and the increased friction can slow down the speed of the conveying belt 21, which can affect the working efficiency of the equipment. The use of the ball 6 can change the sliding friction into rolling friction, greatly reduce the friction, reduce the energy damage and ensure the normal operation of the equipment.

[0040] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
