Description

Technical Field

[0001] The utility model belongs to the technical field of production equipment for degradable coated composite cloths, in particular to a web laying machine for producing degradable coated composite cloths. Background Art

[0002] In recent years, with the continuous development of spunlace non-woven fabric technology, its quality has also been continuously improving. In order to meet the needs of downstream users, the industry has optimized and adjusted the raw materials and processes of spunlace non-woven fabrics to develop special spunlace non-woven fabrics that meet performance requirements and expand the application areas of spunlace non-woven fabrics.

[0003] Taking degradable laminated fabric as an example, it has broad application prospects and development potential in high-end gift packaging and decoration. Degradable laminated fabric uses a 100% degradable spunlace nonwoven fabric as its base, and then coats the base fabric with a double layer of film, preferably a biodegradable polymer material with excellent compatibility with the base material. From the selection of raw materials to the processing of the production process, degradable laminated fabric is environmentally friendly and recyclable, showing great application prospects.

[0004] In the preparation process of degradable coated composite fabric, the degradable spunlace non-woven fabric needs to be processed twice to form a composite coated fabric. Therefore, certain requirements are placed on the spunlace non-woven fabric. The surface of the spunlace non-woven fabric needs to be uniform and the weight fluctuation is small in order to meet the index requirements after coating.

[0005] In the preparation of spunlace nonwoven fabrics with degradable coated base fabrics, different degradable raw materials need to be used in combination, and generally some raw materials contain static electricity, which has a certain impact on the laying process in the production process. For example, with regard to the characteristics of the semi-intersecting line laying machine, when using different raw materials, due to the influence of static electricity and the mesh curtain, the laying machine is prone to wrinkles when laying the mesh, and the two ends are prone to unevenness, affecting the overall uniformity of the product. After research, it was found that eliminating static electricity and increasing friction can effectively improve this problem. In the prior art, there is a method of adding a humidifying mechanism to humidify the mesh mechanism to achieve the purpose of removing static electricity, but these modified laying machines always have problems when in use, such as inconvenient use, unreasonable structural settings leading to interference during equipment operation, unstable product quality after the laying machine has been running continuously for a certain period of time, or the humidifying mechanism is relatively complicated and inconvenient for operators to operate.

The humidifying device 5 includes a spray pipe 51 and an ultrasonic humidifier 52. The spray pipe 51 is connected to the ultrasonic humidifier 52 through a pipeline. A plurality of spray holes 54 are opened on the spray pipe 51. The water mist after the water is treated by the ultrasonic humidifier 52 is sent out through the spray holes 54 of the spray pipe 51; the feeding end of the first material laying roller group 1 is provided with an electrostatic eliminator 6, and the top of the traction roller group I2 and the mesh curtain 4 are both provided with a spray pipe 51. The spray holes 54 on the spray pipe 51 are facing the traction roller group I2 or the mesh curtain 4. The cotton web 7 is sent through the traction roller group I2 through the first material laying roller group 1, and then sent to the mesh curtain 4 under the stretching and traction of the traction roller group I2 and the traction roller group II3. After folding, it is sent out of the web laying machine through the mesh curtain roller group 8.

[0037] In this embodiment, the spray pipe 51 provided above the traction roller group I 2 has the same structure as the spray pipe 51 provided above the mesh curtain 4 . The spray pipes 51 at both locations can be connected to the ultrasonic humidifier 52 after being merged into the pipe I 53 through a pipe.

[0038] In this embodiment, reference Figure 1 The following describes a preferred embodiment of a pulling roller group I2 and a pulling roller group II3. The pulling roller group I2 includes a first pulling roller 21, a first pulling roller group 22, a conveyor belt 23, and several guide rollers 24; the pulling roller group II3 includes a second pulling roller 31, a second pulling roller group 32, a conveyor belt 33, and several guide rollers 34. The pulling roller group I2 and the pulling roller group II3 cooperate in a reciprocating motion to stretch and pull the cotton web 7 to fold. Figure 4 , Figure 4 The diagram shows another state where the traction roller group Ⅰ2 and the traction roller group Ⅱ3 of the web laying machine clamp the cotton web 7 (moving to Figure 1 left side).

[0048] The difference between this embodiment and embodiments 1-3 is that the spray pipe 51 is fixed above the traction roller group I2 and the mesh curtain 4 through the support frame 10. Figure 5 , to avoid affecting the normal operation of the web laying machine. In addition, the support frame 10 can be designed as a telescopic bracket, and the distance between the spray pipe 51 and the cotton net 7 can be adjusted according to demand.
