Description

Technical Field

[0001] The utility model belongs to the technical field of looms, and in particular relates to a metal mesh loom. Background Art

[0002] The wire mesh loom is a commonly used machine for weaving wire mesh. The current wire mesh loom includes a frame, a warp feeding mechanism, a heald frame, a steel buckle, a weft beating mechanism, and a winding mechanism. The metal wire of the existing woven mesh is relatively soft and has high ductility. During the mesh weaving process, the mesh surface hardly shrinks, the metal wire and the central axis of the steel buckle are in the same direction, and the longitudinal metal wire and the steel buckle are basically not in contact. Therefore, during the weaving process, there is no wear between the steel buckle and the warp wire, and the steel buckle has a long service life.

[0003] For the high-elastic metal mesh, the mesh has the advantages of high impact resistance and not easy to deform after impact. The metal wire weaving the high-elastic metal mesh has the characteristics of high tensile strength, high hardness and low ductility. If the current weaving machine is used to weave a high-elastic metal mesh, the following defects exist: First, after the weft beating mechanism introduces the straightened weft wire, during the weaving process, the diameter of the weft wire is equal to that of the warp wire, and the weft wire is bent after being woven into a mesh. Due to the low ductility of the weft wire, the length of the weft wire will be shortened after weaving, causing the width of the mesh to shrink, and the warp wires on both sides of the mesh to bend toward the middle direction, thereby causing the warp wire to form a certain angle with the center line of the steel buckle. During the forward and backward movement of the steel buckle, the warp wire rubs against the side of the steel buckle, and the service life of the steel buckle is greatly reduced. After the steel buckle is worn, a slide groove is formed on the side of the steel buckle, resulting in uneven mesh holes and easy wire breakage; second, during the process of the steel buckle pushing the weft wire forward, the hardness of the warp wire and the weft wire is large, and the friction between the weft wire and the warp wire during the weaving process is large, resulting in large bending of the weft wire, poor flatness of the mesh surface, and serious shrinkage of the mesh surface. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a metal mesh weaving machine with good mesh flatness, uniform mesh holes and long service life of steel buckles.

[0005] To solve the above problems, the technical solution adopted by the metal mesh loom of the utility model is: including a frame, a warp feeding mechanism, a heald frame, a steel buckle, a weft beating mechanism, and a winding mechanism, and a lubricating oil spraying mechanism is arranged between the heald frame and the warp feeding mechanism.

[0006] Its additional technical features are:

[0007] The lubricating oil spraying mechanism is an atomizing nozzle located on both sides of the warp let-off mechanism;

[0008] The lubricating oil spraying mechanism is a spray pipe, on which an atomizing nozzle is arranged, and the spray pipe is located above or below the warp;

[0009] The lubricating oil spraying mechanism is 20-70cm away from the steel buckle.

[0010] Compared with the prior art, the metal mesh loom provided by the utility model has the following advantages: first, since it includes a frame, a warp feeding mechanism, a heald frame, a steel buckle, a beating-up mechanism, and a winding mechanism, a lubricating oil spraying mechanism is arranged above the warp feeding mechanism behind the heald frame, and the warp is passed from the warp feeding mechanism through the heald frame and the steel buckle to the winding mechanism, and the end is wound on the winding shaft of the winding mechanism; the heald frame is driven up and down and the steel buckle is driven forward and backward by the crankshaft, and the beating-up mechanism drives the weft to pass through, so as to complete the mesh weaving. The winding shaft of the winding mechanism rotates, and while the warp yarns advance to weave the mesh, lubricating oil is sprayed on the warp yarns from above, below or on both sides of the warp yarns through the lubricating oil spraying mechanism; the winding shaft of the winding mechanism rotates, and the mesh is wound on the winding shaft until the weaving is completed. Before the warp yarns enter the heald frame and the steel buckle, the lubricating oil is sprayed on the warp yarns through the lubricating oil spraying mechanism. When the warp yarns are sprayed with lubricating oil, the friction between the steel buckle and the longitudinal yarn is small when the longitudinal yarn passes through the steel buckle, the wear of the steel buckle is small, and the longitudinal yarn is The friction between the warp and the transverse wire is reduced, the bending of the transverse wire after weaving the mesh is smaller than that of the previous method, the total length of the transverse wire is shortened less, the mesh shrinks less, the clamping between the longitudinal wire and the center line of the steel buckle is reduced, and the friction between the longitudinal wire and the steel buckle is further reduced; secondly, since the lubricating oil spraying mechanism is an atomizing nozzle located on both sides of the warp feeding mechanism, the lubricating oil is sprayed from above the warp wire in a mist form, and the spraying is more uniform. The lubricating oil falls on the upper surface of the longitudinal wire. Under the action of gravity, when the longitudinal wire reaches the steel buckle position, the lubricating oil just reaches the side of the longitudinal wire, so that the lubricating oil is located on the contact surface between the longitudinal wire and the inner side of the steel buckle, and the lubrication effect is better; thirdly, since the lubricating oil spraying mechanism is a spray pipe, an atomizing nozzle is arranged on the spray pipe, and the spraying is more uniform; fourthly, since the lubricating oil spraying mechanism is 20-70cm away from the steel buckle, under the action of gravity, when the longitudinal wire reaches the steel buckle position, the lubricating oil just reaches the side of the longitudinal wire, so that the lubricating oil is located on the contact surface between the longitudinal wire and the inner side of the steel buckle. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic diagram of the structure of the metal mesh loom of the utility model;

[0012] Figure 2 It is a schematic diagram of the structure of the spray pipe. DETAILED DESCRIPTION

[0013] The structure and operation principle of the metal mesh loom of the utility model are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0014] For the sake of convenience and to avoid ambiguity, the mesh side is the front of the loom, and the warp thread feeding side is the back of the loom.

[0015] like Figure 1As shown, it is a schematic structural diagram of the metal mesh loom of the utility model. The metal mesh loom of the utility model includes a frame 1, a warp feeding mechanism 2, a heald frame 3, a steel buckle 4, a weft beating mechanism 5, and a winding mechanism 6. A lubricating oil spraying mechanism 7 is arranged above the warp feeding mechanism 2 behind the heald frame 3.

[0016] The end of the warp is passed from the warp feeding mechanism 2 through the heald frame 3 and the steel buckle 4 to the take-up mechanism 6, and the end of the warp is wound on the take-up shaft of the take-up mechanism 6; the heald frame 3 is driven to move up and down and the steel buckle 4 is driven to move forward and backward by the crankshaft, and the beating mechanism 5 drives the weft to pass through the opening formed by the warp to complete the mesh weaving; the take-up shaft of the take-up mechanism 6 rotates, and while the warp moves forward to weave the mesh, lubricating oil is sprayed on the warp from above the warp, below the warp or on both sides of the warp through the lubricating oil spraying mechanism; the take-up shaft of the take-up mechanism rotates, and the mesh is wound on the take-up shaft until the weaving is completed. Before the warp yarns enter the heald frame 3 and the steel buckle 4, lubricating oil is sprayed on the warp yarns through the lubricating oil spraying mechanism 7. After the warp yarns are sprayed with lubricating oil, they enter the heald frame and the steel buckle. When the longitudinal yarns pass through the steel buckle, the friction between the steel buckle and the longitudinal yarn is small, the steel buckle wears less, and the friction between the longitudinal yarn and the transverse yarn becomes smaller. After weaving, the bending of the transverse yarns behind the mesh becomes smaller compared with the previous method, the total length of the transverse yarns is shortened less, the mesh shrinks less, and the clamping between the longitudinal yarns and the center line of the steel buckle becomes smaller, which further reduces the friction between the longitudinal yarns and the steel buckle.

[0017] The lubricating oil spraying mechanism 7 is an atomizing nozzle 8 located on both sides of the warp feeding mechanism. The lubricating oil is sprayed from above the warp in the form of mist, and the spraying is more uniform. The lubricating oil falls on the upper surface of the longitudinal wire. Under the action of gravity, when the longitudinal wire reaches the steel buckle position, the lubricating oil just reaches the side of the longitudinal wire, so that the lubricating oil is located in contact with the inner side of the longitudinal wire and the steel buckle, and the lubrication effect is better.

[0018] Of course, the lubricating oil spraying mechanism 7 can spray lubricating oil or lubricating liquid.

[0019] like Figure 2 As shown, the lubricating oil spraying mechanism 7 is a spraying pipe 9, and at least one atomizing nozzle 10 is arranged on the spraying pipe 9, so that the spraying is more uniform.

[0020] The lubricating oil spraying mechanism 7 is 20-70cm away from the steel buckle. Under the action of gravity, when the longitudinal wire reaches the steel buckle position, the lubricating oil just reaches the side of the longitudinal wire, so that the lubricating oil is located on the contact between the longitudinal wire and the inner side of the steel buckle.

[0021] The protection scope of the present invention is not limited to the above embodiments. As long as the structure is the same or similar to the metal mesh loom structure of the present invention, it falls within the protection scope of the present invention.
