Description

Technical Field

[0001] The utility model relates to the field of wire drawing machines, and particularly relates to a wire drawing machine for producing flour bags. Background Art

[0002] After flour is produced, it often needs to be packaged using woven bags. A woven bag is a cloth woven from fiber filaments drawn from a plastic film and then processed into various products. It is different from other chemical fiber filaments and is not knitted into cloth but woven into cloth. Woven bags are usually made of plastic materials such as polypropylene and polyethylene, and have advantages such as waterproof, moisture-proof, and impact-resistant. These characteristics enable woven bags to effectively protect goods from damage during packaging and transportation. The production of woven bags is a complex and delicate process, mainly involving multiple steps such as raw material preparation, melting and extrusion, forming, cooling, and wire drawing. Among them, wire drawing is to stretch the produced strip through a wire drawing machine to make it thinner, longer, and have a certain strength and toughness. When the wire drawing roller of the wire drawing machine is performing wire drawing work, there is a certain probability that some dust and debris will adhere to its surface. When the strip used for the production of woven bags is stretched by the wire drawing roller of the wire drawing machine, the dust and debris adhering to the surface of the wire drawing roller will easily adhere to the strip, thereby contaminating the strip and further reducing the quality of the woven bag. Therefore, in order to improve the quality of the produced woven bags, a wire drawing machine for producing flour bags is needed to solve the above problems. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a wire drawing machine for producing flour bags, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A wire drawing machine for producing flour bags includes an equipment housing. A plurality of wire drawing rollers are installed on one side of the equipment housing. Two adjusting structures are symmetrically and fixedly installed at one end of the equipment housing. The adjusting structure consists of a mounting block, a lead screw, a rotating block, and an anti-detachment column. There are two lead screws, which are symmetrically and fixedly installed at the upper and lower ends of the mounting block. There are two rotating blocks, which are respectively fixedly installed at one end of the two lead screws. The lead screws and the rotating blocks are both rotatably installed on the mounting block. Two roller surface cleaning components are installed on the four lead screws of the two adjusting structures. The roller surface cleaning component consists of a substrate, an arc-shaped support plate, and an arc-shaped cleaning plate. There are several arc-shaped support plates, which are all fixedly installed at one end of the substrate. The arc-shaped cleaning plate is fixedly installed on the arc-shaped support plate, and the arc-shaped cleaning plate can be in contact with the wire drawing roller.

[0020] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a wire drawing machine for flour bag production includes an equipment housing 1, a plurality of wire drawing rollers 2 are installed on one side of the equipment housing 1, two support brackets 5 are symmetrically fixedly installed at one end of the equipment housing 1 and below the plurality of wire drawing rollers 2, a mounting bracket 6 is fixedly installed at the upper end of the equipment housing 1, two cylinders 7 are fixedly installed at the upper end of the mounting bracket 6, and a pressing roller 8 is rotatably installed on the telescopic rods of the two cylinders 7 and below the mounting bracket 6, and two adjustment structures 3 are symmetrically fixedly installed at one end of the equipment housing 1, and the adjustment structure 3 consists of a mounting block 9, a screw rod 10, a rotating block 11 and an anti-slip column 1 8, there are two screw rods 10 and they are symmetrically fixedly installed at the upper and lower ends of the mounting block 9, there are two rotating blocks 11 and they are respectively fixedly installed at one end of the two screw rods 10, the screw rods 10 and the rotating blocks 11 are both rotatably installed on the mounting block 9, and two roller surface cleaning assemblies 4 are installed on the four screw rods 10 on the two adjustment structures 3. The roller surface cleaning assembly 4 consists of a base plate 14, an arc support plate 16 and an arc cleaning plate 17. There are several arc support plates 16 and they are all fixedly installed at one end of the base plate 14. The arc cleaning plate 17 is fixedly installed on the arc support plate 16, and the arc cleaning plate 1 7 can contact with the drawing roller 2. When producing woven bags, the plastic film extruded by the extruder undergoes cooling, shaping and other processes to form a film with a certain width and thickness. The film will then be cut into strips of a certain width. The strips then pass over the drawing roller 2 on the drawing machine, and are stretched by the rotating drawing roller 2. At the same time, the pressure roller 8 driven by the cylinder 7 cooperates with one of the drawing rollers 2 to tighten the strip. In this process, the position of the roller surface cleaning assembly 4 can be adjusted by rotating the screw rod 10 on the adjustment structure 3, so that the arc cleaning plate 17 can contact the surface of the rotating drawing roller 2. As the drawing roller 2 rotates, the arc-shaped cleaning plate 17 will generate friction with the surface of the drawing roller 2, and the arc-shaped cleaning plate 17 can wipe off the dust and debris attached to the surface of the drawing roller 2 in the first time, and finally the cleanliness of the surface of the drawing roller 2 can be guaranteed, so that the strip stretched by the drawing roller 2 is not easy to be attached with dust and debris, thereby improving the quality of the produced woven bags, and the adjustment structure 3 can adjust the position of the roller surface cleaning component 4, so that the roller surface cleaning component 4 can be close to the surface of the drawing roller 2, thereby ensuring that the roller surface cleaning component 4 has a better cleaning effect on the drawing roller 2.

[0022] Further, the adjusting structure 3 is on the same side as the wire drawing roller 2. The mounting block 9 is fixedly connected to the equipment housing 1. An anti - detachment groove 12 is formed in the mounting block 9. A mounting hole 13 is formed in the mounting block 9. The mounting hole 13 penetrates the mounting block 9 up and down and is simultaneously communicated with the anti - detachment groove 12. The anti - detachment column 18 is rotatably mounted in the anti - detachment groove 12, and the lead screw 10 is rotatably mounted in the mounting hole 13. The lead screw 10 can be rotated by rotating the rotating block 11. When the lead screw 10 rotates, the anti - detachment column 18 will also rotate. As the lead screw 10 and the anti - detachment column 18 rotate on the mounting block 9, the roller surface cleaning assembly 4 will move on the lead screw 10.

[0023] Further, a threaded hole 15 is formed in the substrate 14 of the roller surface cleaning assembly 4. The substrate 14 is mounted on the lead screw 10 through the threaded hole 15. When the two roller surface cleaning assemblies 4 move away from each other, the arc - shaped cleaning plate 17 on the roller surface cleaning assembly 4 will approach the corresponding wire drawing roller 2. Conversely, when the two roller surface cleaning assemblies 4 approach each other, the arc - shaped cleaning plate 17 on the roller surface cleaning assembly 4 will move away from the corresponding wire drawing roller 2.
