Description

Technical Field

[0001] This utility model belongs to the technical field of winding machine equipment and relates to a winding machine switching wire stop hook. Background Technology

[0002] The winding machine includes a shift fork, a wire shift hook, a winding machine body, a wire stop ceramic component, a wire stop rod, and a forming plate bracket; the forming plate bracket, the wire stop ceramic component, and the wire stop rod are respectively fixed on side A of the winding machine body, and a tail groove is provided on side A;

[0003] Before the winding machine is fully wound, the shift fork moves the wire bundle back and forth between the wire stop ceramic piece and the wire stop rod; when the winding machine is fully wound, the wire shift hook moves the wire to the vicinity of the paper tube tail wire groove. At this time, the wire stop hook needs to block the wire bundle to avoid wire jumping and breakage.

[0004] like Figure 1 , 2 As shown, the wire-stopping hook includes a U-shaped rod I, a connecting rod, a wire guide groove, and a tail hook; the wire guide groove includes rods I, II, and III connected in sequence; rods I and II are located on the same horizontal plane, with an angle of 120° to 130° between them; the angle between rods II and III is 90°, and rod III is located below the horizontal plane containing rod II, with an angle of 70° to 75° between the horizontal plane containing rod III and rod II; rods I and III are located on the same side of the length direction of rod II; the length direction of the connecting rod is parallel to the length direction of rod II; the end of rod I not connected to rod II is fixedly connected to one end of the connecting rod; one end of the U-shaped rod I is fixedly connected to the other end of the connecting rod. The tail hook is an L-shaped rod formed by connecting rod IV and rod V. The end of rod IV that is not connected to rod V is fixedly connected to the end of rod III that is not connected to rod II. The length direction of rod V is parallel to the length direction of rod II, and rod V and rod II are located on both sides of the length direction of rod IV. Rod II is perpendicular to side A. The rod V of the tail hook is used to insert into the tail groove. The U-shaped rod I is fixedly connected to the forming plate bracket by screws. Through the connection relationship between the tail hook and the tail groove, and the connection relationship between the U-shaped rod I and the forming plate bracket, the wire-blocking hook is fixed on the winding machine. When the winding machine is switched, the wire-moving hook moves the wire to the vicinity of the paper tube tail wire groove, that is, the wire-moving hook moves the wire bundle to the connecting rod.

[0005] However, during the plucking process, the tension of the silk fluctuates, and the amplitude of the silk bundle shaking increases, making it impossible for the silk-blocking hook to effectively block the silk bundle, resulting in silk skipping and breakage.

[0006] Patent CN201720092194.1 mentions a wire-blocking device, which installs a wire-blocking strip on a baffle to prevent the wire guide hook from jumping off the wire splitter plate due to large vibration amplitude during wire bundle switching. However, this wire-blocking device cannot solve the problem that the wire-blocking hook cannot effectively block the wire bundle.

[0007] Therefore, it is of great significance to study a switching wire stop hook for a winding machine to solve the problems existing in the prior art. Utility Model Content

[0008] The purpose of this invention is to solve the problems existing in the prior art and to provide a winding machine switching wire stop hook.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A wire-stopping hook for a winding machine includes a U-shaped rod I, a connecting rod, a wire guide groove, and a tail hook. The wire guide groove includes rods I, II, and III connected in sequence. Rods I and II are located on the same horizontal plane, with an angle of 120° to 130° between them. The angle between rods II and III is 90°, and rod III is located below the horizontal plane containing rod II, with an angle of 70° to 75° between the horizontal plane containing rod III and rod II. Rods I and III are located on the same side of the length direction of rod II. The length direction of the connecting rod is parallel to the length direction of rod II. The end of rod I not connected to rod II is fixedly connected to one end of the connecting rod. One end of the U-shaped rod I is fixedly connected to the other end of the connecting rod. The tail hook is an L-shaped rod formed by connecting rods IV and V, with the end of rod IV not connected to rod V fixedly connected to the end of rod III not connected to rod II. The length direction of rod V is parallel to the length direction of rod II, and rods V and II are respectively located on the same side of the length direction of rod IV. The winding machine includes a shift fork, a wire shift hook, a winding machine body, and a forming plate support. The forming plate support is fixed on side A of the winding machine body, and side A has a tail groove. Rod II is perpendicular to side A. The wire shift hook is set on the winding machine body. When the winding machine is switched, the wire shift hook is used to move the wire bundle towards the connecting rod. The rod V of the tail hook is used to insert into the tail groove. The U-shaped rod I is fixedly connected to the forming plate support by screws. Through the connection relationship between the tail hook and the tail groove, and the connection relationship between the U-shaped rod I and the forming plate support, the wire stop hook is fixed on the winding machine. It also includes rod VI. One end of rod VI is fixedly connected to the end of the connecting rod away from rod I. The length direction of rod VI is parallel to that of rod II. Let the side of the forming plate support opposite to side A be side B. Along the direction perpendicular to side A, the distance between side B and the wire shift hook is a. Let half of the shaking amplitude in the direction perpendicular to side A when the wire bundle moves towards the connecting rod be b. The length of rod VI is greater than the sum of a and b.

[0011] In the prior art, during the process of the wire moving hook propelling the wire bundle toward the connecting rod, the tension of the wire fluctuates and the amplitude of the shaking increases, which may result in the wire not being able to move accurately to the connecting rod, causing the wire blocking hook to fail to stop the wire. This application adds a rod VI to block the wire bundle after the amplitude of shaking increases.

[0012] As a preferred technical solution:

[0013] The winding machine switching wire stop hook described above also includes a U-shaped rod II and a rod VII; the length direction of rod VII is parallel to the length direction of rod VI, and the two ends of the U-shaped rod II are fixedly connected to rod VII and rod VI respectively; let the end of rod VII away from U-shaped rod II be end c, and one end of U-shaped rod I is fixedly connected to the connecting rod through end c (that is, one end of U-shaped rod I is connected to the connecting rod through rod VII, U-shaped rod II, and rod VI). This design allows the wire stop hook to be integrally formed.

[0014] As described above, the winding machine switching wire stop hook has the following lengths: rod I is 10mm long, rod II is 22mm long, rod III is 20mm long, rod IV is 15mm long, rod V is 5mm long, rod VI is 40mm long, and rod VII is 30mm long.

[0015] As described above, the diameter of rods I, II, III, IV, V, VI, and VII in the winding machine switching wire stop hook is 3mm.

[0016] As described above, a winding machine with a wire-stopping hook is provided. The winding machine also includes a wire-stopping ceramic component, which is fixed on side A and located directly below the tail groove.

[0017] As described above, a winding machine with a wire stop hook also includes a wire stop rod, which is fixed on side A. Before the wire bundle moves toward the connecting rod, a shift fork moves the wire bundle between the wire stop ceramic piece and the wire stop rod.

[0018] Beneficial effects:

[0019] This utility model discloses a winding machine switching wire stop hook, which adds a rod VI to block the wire bundle after the vibration amplitude increases, thus avoiding the problem of wire breakage caused by wire jumping. Attached Figure Description
