The electromagnet 44 is externally connected to a pulse switch and a power supply. The pulse switch intermittently energizes the electromagnet 44. After power is turned on, a magnetic repulsion force is generated between the electromagnet 44 and the magnetic block. The power is turned off and reset under the action of the spring 46, and then the plurality of swing plates 30 are driven to swing back and forth rapidly through the slide plate 45, and the fallen raw materials are further mixed after passing through the plurality of swing plates 30.

[0051] In addition, a dust collection chamber 23 is provided in the web laying equipment 3.

[0052] Straw, coconut palm and environmentally friendly low-melting-point cotton are fed into the mixing equipment, and after mixing, they are fed into the opening equipment 2 through the first belt conveyor 7. After opening, they are fed into the laying equipment 3 through the second belt conveyor 8, and are transported to the opening cavity 14 through a pair of first feeding rollers 13. The first driving shaft 38 drives the opening net cylinder 17 to rotate, and the raw materials are opened twice by the evenly distributed spikes 16. The extrusion force of multiple protrusions 15 is combined to improve the opening effect. The opened raw materials enter the discharge channel 1 9, at this time the air inlet pipe 11 supplies air to the air distribution pipe 49, and then blows it out through a row of blowing pipes 48, blowing the environmentally friendly low-melting point cotton and a small amount of coconut palm and straw adhering to the spikes to the discharge channel 19 at the same time, avoiding the environmentally friendly low-melting point cotton from being separated from the straw and coconut palm. At the same time, the rotation of the unloading roller 20 drives the rotation of multiple scraping plates 21, and cooperates with the blowing pipe 48 to complete the intermittent feeding process.

After a certain thickness, the excess part is scraped off by the blocking plate 29, and at the same time, the transition net cylinder 28 generates negative pressure through the second negative pressure pipe 40 and the plurality of second negative pressure holes 43, so that the scraped raw materials are adsorbed. When the raw materials adsorbed on the transition net cylinder 28 move to the area between the two partitions 42, an independent space is formed between the two partitions 42, the negative pressure disappears or the suction force is weakened, and the raw materials are thrown to the blocking plate 29 under the action of centrifugal force, realizing the continuous and uniform discharging process.

[0054] The raw materials fall through the blocking plate 29, and the solenoid 44 is intermittently powered through the pulse switch. After being powered on, the solenoid 44 and the magnetic block generate magnetic repulsion, and after being powered off, the solenoid 44 is reset under the action of the spring 46, and then the plurality of swing plates 30 are driven by the slide plate 45 to high-frequency reciprocating swing. The falling raw materials are further scattered by the plurality of swing plates 30, so that the raw materials are more uniform in the width direction. At the same time, the falling raw materials will be shaken due to the difference in their own weight, and the falling speed of coconut husk and straw is faster than that of environment-friendly low-melting-point cotton, so that a layered phenomenon is formed during laying. The environment-friendly low-melting-point cotton is concentrated in the upper layer and mixed with a small amount of straw and coconut husk, and the lower layer is an interlaced layer of straw and coconut husk. The uniformly laid net mat is sent into a pair of hot pressing rollers 32 through the second feeding roller 31. The hot pressing rollers 32 melt part of the environment-friendly low-melting-point cotton while being extruded, so that it is melted as an adhesive. The environment-friendly low-melting-point cotton in the upper layer is melted to form a net-shaped thin layer, which bonds the straw and coconut husk in the upper and lower layers, thereby ensuring that the whole is more stable during container preparation, and better fertilizer and water retention can be achieved. Subsequently, the third feeding roller 33 is sent into the slitting equipment 5, the cylinder 34 is started to drive the blade 35 to move downward to complete the slitting process, and the fourth feeding roller 36 is continuously sent to a pair of winding rollers 37 to be wound.
