Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic tarpaulin production, in particular to a plastic tarpaulin weaving machine which is convenient for heat recovery and utilization. Background Art
[0002] Tarpaulin (or waterproof cloth) is a high-strength waterproof material with good toughness and softness. It is often used as canvas (oil canvas), polyester with polyurethane coating or made into polyethylene plastic.
[0003] Plastic tarpaulin weaving machine is a kind of equipment used to make plastic tarpaulin, and its main function is to weave plastic filaments or plastic fibers into tarpaulin. Plastic tarpaulin is usually used to build temporary awnings, cargo covers, agricultural covers and other covers that need to be waterproof, windproof and durable.
[0004] This machine usually consists of a weaving mechanism and a control system. The weaving mechanism consists of a series of needles or shuttles that are mechanically or electronically controlled to weave plastic filaments or fibers into tarpaulins. The control system is used to adjust the weaving speed, tension and other parameters to ensure the quality and production efficiency of the tarpaulin.
[0005] The working principle of the plastic tarpaulin weaving machine is to introduce plastic filaments or fibers from a reel or a tray into a weaving mechanism, and then weave them into tarpaulins through the reciprocating motion of a needle or a shuttle. During the weaving process, colors or reinforcing materials can be added as needed to meet different usage requirements.
[0006] The search announcement number CN214214814U discloses a high-efficiency plastic tarpaulin weaving machine. The patent drives the material to extrude from two extrusion dies to form two flat films through an extrusion component. The double films not only improve the film-extrusion speed and production efficiency of the tarpaulin, but also exchange heat with the flat film through the cooling component, so that the flat film can be cooled, and the flat film can be repeatedly circulated and cooled, with good cooling effect. At the same time, water resources can be saved, and there is no need for subsequent drying, which improves the production efficiency of the tarpaulin and reduces the cost. The flat film is cut into a certain width by the cutting component, and the tarpaulin flat film is rolled up by the winding component.
[0007] In the above-mentioned prior art solution, the processed plastic tarpaulin is fitted onto the side wall of the metal heat exchange plate so that the water inside the metal heat exchange plate absorbs the heat of the plastic tarpaulin. The water that absorbs the heat from the tarpaulin is directly cooled by the cooling component, and the heat in the water that absorbs the heat is not utilized, resulting in high power consumption of the cooling component and inconvenience in use.
[0008] To this end, we propose a plastic tarpaulin weaving machine that is convenient for heat recovery. Utility Model Content
