Description

Technical Field

[0001] The utility model relates to the technical field of woven bag material processing, in particular to a woven bag hot-melt wire drawing production device. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. The process is to mix the polypropylene resin granules, heat and draw them through a plastic drawing machine, and then reel them up and weave them into bags.

[0003] The raw materials are cut into wires, and then heated and drawn into thinner raw material wires. At this time, the raw material wires are at a higher temperature, are relatively soft, and have greater variability. In order to facilitate quick winding, the newly drawn plastic wires need to be cooled. The existing cooling method mostly uses water cooling, but after water cooling, a large amount of water stains will be attached to the surface of the raw material wires, which reduces the friction on the rollers, makes it easy to slip, and is not convenient for handling and subsequent processing. Utility Model Content

[0004] In order to solve the problem that the existing water cooling causes water stains on the surface of raw material wires, the utility model provides a woven bag hot-melt wire drawing production device.

[0005] The technical solution of the utility model is achieved through the following scheme: a woven bag hot-melt wire drawing production device, including a spray die head and a molding machine arranged below the spray die head, the discharge end of the molding machine is provided with a cutting knife and a plurality of auxiliary rollers, the molding machine, the heating wire drawing machine and the water cooling box are arranged linearly, the molding machine, the heating wire drawing machine and the water cooling box are connected through the raw wire, the discharge end of the water cooling box is provided with a dewatering device, a drying device and an electrostatic eliminator, the raw wire passes through the dewatering device, the drying device and the electrostatic eliminator in sequence.

[0006] Through the above technical scheme, by setting a water removal device and a drying device at the discharge end of the water cooling box, the water stains remaining on the raw silk after water cooling can be effectively removed, and the raw silk can be kept dry to avoid the influence of moisture on subsequent production steps, thereby improving production efficiency and product quality. The static electricity generated by the raw silk after drying can be effectively reduced by the static eliminator.

[0007] Preferably, the water removal device comprises a sponge roller and an extrusion knife, the sponge roller is close to the extrusion knife below, and the extrusion knife is fixedly installed at the discharge end of the water cooling box.

[0009] Preferably, the raw material wire passes through between the air outlet and the sponge roller, and the extrusion knife is provided with a slope.

[0010] Through the above technical scheme, the sponge roller can squeeze out the moisture on the surface of the raw silk more effectively. The close proximity of the extrusion knife ensures that the moisture absorbed by the sponge roller is effectively removed, which not only improves the efficiency of moisture removal, but also improves the service life of the sponge roller and reduces production problems caused by humidity. The air flow brought by the fan further helps to remove the moisture on the surface of the raw silk. The slope on the extrusion knife may help to more effectively guide the squeezed water to the water cooling box.

[0011] Preferably, the drying device comprises a first drying rod and a second drying rod, the first drying rod is located above the second drying rod, and the raw silk passes through the first drying rod and the second drying rod.

[0012] Preferably, the plurality of auxiliary rollers include a first auxiliary roller and a second auxiliary roller, the second auxiliary roller is located obliquely above the first auxiliary roller, and the cutting knife is located between the first auxiliary roller and the second auxiliary roller.

[0013] Through the above technical scheme, the first drying rod and the second drying rod cooperate to evenly dry the raw silk, ensuring its overall dryness and avoiding excessive drying or wetting on one side or part. The second auxiliary roller is positioned obliquely above to better guide the raw material, allowing it to pass smoothly through the cutting area, effectively improving the accuracy and stability of cutting.

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. The utility model arranges a water removal device and a drying device at the discharge end of the water cooling box, thereby effectively removing water stains remaining on the raw silk after water cooling, and keeping the raw silk dry, avoiding the influence of moisture on subsequent production steps, improving production efficiency and product quality, and the static electricity generated by the raw silk after drying can be effectively reduced by the static eliminator.

[0016] 2. The sponge roller can squeeze out the moisture on the surface of the raw silk more effectively.

The extrusion knife is provided with a slope, which can more effectively guide the squeezed water to flow to the water cooling box.

[0028] The dewatering device 3 includes a sponge roller 31 and an extrusion knife 32. The sponge roller 31 is close to the extrusion knife 32 below. The extrusion knife 32 is fixedly installed at the discharge end of the water cooling box 2. The dewatering device 3 also includes a fan 33, an air duct 34 and an air outlet 35. The fan 33 is installed on one side of the discharge end of the water cooling box 2. The fan 33 is connected to the air outlet 35 through the air duct 34. The air outlet 35 is located above the sponge roller 31. The raw material 6 passes between the air outlet 35 and the sponge roller 31. The extrusion knife 32 is provided with a slope. Through the slope on the extrusion knife 32, the cooling water squeezed out from the sponge roller 31 flows back to the water cooling box 2 to prevent moisture from remaining on the product. The extrusion knife 32 is made of waterproof and heat-resistant hard plastic material, which can effectively resist water stains and high temperatures. The service life of the equipment is improved, the durability and stability of the equipment are improved, the sponge roller 31 is an auxiliary roller with a layer of absorbent sponge, which absorbs the moisture on the lower surface of the raw silk 6, and the moisture is squeezed out by the extrusion knife 32 to increase the service life. The air outlet 35 of the fan 33 is facing the upper surface of the raw silk 6, and the evaporation and removal of moisture are accelerated by blowing, so as to achieve the effect of rapid drying. The water cooling box 2 is provided with a water inlet 7 and a drain port 8, and the drain port 8 is located on one side of the bottom of the water cooling box 2.

[0029] The drying device 4 includes a first drying rod 41 and a second drying rod 42. The first drying rod 41 is located above the second drying rod 42. The raw silk 6 passes through the first drying rod 41 and the second drying rod 42. The first drying rod 41 and the second drying rod 42 cooperate to achieve a double drying effect, which can more fully remove the moisture on the surface of the raw silk 6 to ensure the dryness and quality of the product.

The cutting knife 0 is located between the first auxiliary roller 01 and the second auxiliary roller 02. The raw silk 6 passes through the second auxiliary roller 02 and overlaps the first auxiliary roller 01 to enter the heating wire drawing machine 1. Because the two auxiliary rollers are inclined and cooperate with the auxiliary rollers of the heating wire drawing machine 1, the raw material can be straightened without the use of a fixing device and passed through the cutting knife 0 to become the raw silk 6.

[0030] Working principle: the raw material is formed into a raw cloth by a forming machine, and after being guided by several auxiliary rollers, the raw cloth passes through a cutting knife 0 to become a raw wire 6, and further enters a heating wire drawing machine 1 for heating and wire drawing. The raw wire 6 after heating and wire drawing passes through auxiliary rollers and enters a water cooling box 2 for cooling to stabilize the temperature. After water cooling, the raw wire 6 with water stains is transported by a sponge roller 31 to absorb water and complete the dehydration of the lower surface. While the sponge roller 31 rotates and transports, the sponge roller 31 is dehydrated by the extrusion knife 32 below it. At the same time, the fan 33 is started to dehydrate the upper surface of the raw wire 6. The raw wire 6 is further dried through a drying device 4 to ensure the dryness of the raw wire 6. Finally, the raw wire 6 is treated by an electrostatic eliminator 5 to prevent the raw wire 6 from being too dry after drying and generating static electricity, thereby reducing safety hazards.
