Description

Technical Field

[0001] This utility model relates to the field of jacquard machine cutter technology, specifically an adjustable jacquard machine cutter. Background Technology

[0002] A jacquard machine, as a textile tool, uses the interweaving of warp and weft yarns of various colors to create fabrics with specific patterns. It controls the rise and fall of the warp yarns during the weaving process, causing them to float on the fabric surface and form the desired pattern. Currently, jacquard weaving involves creating a three-dimensional, embossed pattern by interlacing warp and weft yarns. Therefore, the drawbar of the jacquard machine plays a crucial role in this process.

[0003] The prior art includes a lightweight, high-strength jacquard machine cutter with application number 202021471211.0. This utility model relates to the field of mechanical technology and includes a cutter body. The cutter body is a high-strength carbon fiber cutter. The cutter body consists of a cutter head, a cutter body, and a cutter handle. The cutter head is integrally formed on the lower edge of the cutter body, and the cutter handle is integrally formed on the upper edge of the cutter body. While this increases strength and ensures that it will not deform during use, thus not affecting the operation of the jacquard machine, it makes it inconvenient to adjust the cutter's height locally, making it difficult to meet the needs of cutters at different heights. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable jacquard machine cutter to solve the problem in the prior art that it is inconvenient to adjust the local height of the cutter, making it difficult to meet the needs of cutters at different heights.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable jacquard machine cutter, including a fixed cutter, the fixed cutter including a handle, a third cutter provided on the lower side of the handle through a first cutter and a second cutter, a cutter head provided at one end of the third cutter through a fourth cutter and a fifth cutter, a first groove provided on one side of the fixed cutter, and a movable cutter inserted longitudinally in the first groove, one end of the movable cutter being threadedly connected to a screw inside the fixed cutter.

[0006] Furthermore, the first and fourth blades have the same thickness, the second and fifth blades have the same thickness, and the first blade has a greater thickness than the second blade.

[0007] Furthermore, the thickness of the first blade is less than the thickness of the handle, and the thickness less than the handle is the same as the thickness of the third blade.

[0008] Furthermore, one end of the screw is rotatably mounted inside the tool holder via a bearing, and one end of the screw is provided with an adjustment handle, which is located in a second groove on one side of the tool holder.

[0009] Furthermore, one end of the movable puller is provided with a threaded hole for threaded connection with the screw, and a vent hole is provided on one side of the bottom of the threaded hole.

[0010] Furthermore, the inner wall of the first groove is provided with a limiting slide groove, and the two sides of the movable pull knife are provided with limiting ribs that slide with the limiting slide groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model describes a broach that is integrally constructed from a handle, a first blade, a second blade, a third blade, a fourth blade, a fifth blade, and a cutting head. The first and fourth blades have the same thickness, as do the second and fifth blades. The first blade is thicker than the second blade, and the first blade is thinner than the handle. The thickness of the first blade is the same as the thickness of the third blade, resulting in a broach with high structural strength, high quality, and convenient processing.

[0013] 2. In this utility model, a movable puller is longitudinally inserted into the first groove on the fixed puller side via a screw rod. One end of the screw rod is rotatably mounted in the handle via a bearing, allowing the movable puller to be raised and lowered by rotating the screw rod. This satisfies the needs of puller use at different local heights, and the adjustment is convenient and quick.

[0014] 3. The present invention has a limiting groove provided on the inner wall of the first groove, and limiting ribs provided on both sides of the movable pull knife that slide with the limiting groove. This allows the limiting ribs and the limiting groove to slide and guide the movable pull knife for lifting and adjusting, which helps to improve the stability of the lifting and adjusting of the movable pull knife.
