Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a gold sheet moving knife and a slicing structure. Background Art

[0002] Most of the existing gold sheet moving knives are made of high-speed tool steel. After working for a long time, they will wear out, resulting in the problem of continuous slicing. In addition, most moving knives have grooves on the blade, which will cause the moving knives to be thin in the middle and thick on both sides. When the moving knives are slicing at high speed, the moving knives are easy to break in the middle, shortening the service life of the moving knives. Summary of the invention

[0003] In order to solve the above problems of the prior art, the utility model provides a gold sheet moving knife and slicing structure, the blade is more wear-resistant, the service life is increased, it is convenient to cut large slices, and the load of the moving knife driving motor is reduced.

[0004] The technical solutions adopted are as follows:

[0005] A gold sheet movable knife comprises a movable knife body, wherein the movable knife body comprises a handle portion and a blade portion, and is characterized in that a hard alloy steel blade is embedded at the cutting edge of the blade portion.

[0006] Furthermore, the handle portion is provided with a cutting surface.

[0007] Furthermore, a groove for avoiding is provided on the side of the blade portion close to the needle drop, and a reinforcing rib is provided on the other side of the blade portion.

[0008] The utility model also provides a gold sheet slicing structure, comprising a gold sheet moving knife, wherein the gold sheet moving knife is any one of the gold sheet moving knives described above.

[0009] Furthermore, it comprises a mounting frame for mounting the fixed knife and the movable knife body.

[0010] Furthermore, the mounting frame is provided with a moving knife shaft for driving the moving knife body, and the moving knife shaft is provided with a slot for engaging with the moving knife body.

[0011] Furthermore, the movable knife shaft of the movable knife body is arranged on the knife handle, and the movable knife shaft is arranged above the fixed knife.

[0012] Furthermore, the movable knife body is provided with a gold plate avoidance gap at the transition between the handle and the blade, and when the movable knife is separated from the fixed knife, a space for the plate is provided between the avoidance gap and the fixed knife.

[0013] Compared with the prior art, the beneficial effects produced by the utility model are:

[0014] The utility model provides a gold sheet moving knife and slicing structure. The moving knife is made of high-speed tool steel as a whole, and a carbide steel blade is embedded at the cutting edge of the blade. While ensuring the toughness of the blade, the wear resistance of the cutting edge is improved. At the same time, a reinforcing rib is provided on the other side of the groove provided on the moving knife, which increases the thickness of the cutting edge and improves the service life of the moving knife. The moving knife is connected to the moving knife shaft through a slot, so that the moving knife is not easy to fall off when rotating at high speed. The moving knife is arranged on the fixed knife, and a gold sheet avoidance gap is provided at the transition between the handle and the blade of the moving knife. When the moving knife is disengaged from the fixed knife, a sheet can be passed between the avoidance gap and the fixed knife, so that a large sheet can pass from under the moving knife. The length of the moving knife can be shortened, and the torque of the cutting knife will increase. When slicing, the required rotation angle is smaller, reducing the load on the motor.

[0023] The present invention is further described below in conjunction with specific embodiments.

[0024] refer to Figure 1-7 A gold sheet movable knife comprises a movable knife body 1, wherein the movable knife body 1 comprises a handle portion 101 and a blade portion 102, wherein a hard alloy steel blade 4 is embedded at the cutting edge of the blade portion 102.

[0025] The blade portion 102 is provided with a groove 2 for avoiding the needle on the side close to the needle drop, and a reinforcing rib 3 is provided on the other side of the blade portion 102. The groove 2 is provided to avoid the needle, and the needle drops more smoothly and is less likely to collide. Since the blade portion 102 is provided with the groove 2, the entire blade portion will become thinner, and it will be more likely to cause wear or even breakage during the high-speed slicing process of the movable knife body 1, so the reinforcing rib 3 is provided on the blade portion 102 to increase the thickness of the blade portion, improve the rigidity of the entire blade portion 101, and make the blade less likely to deform.

[0026] The existing gold sheet moving knife is made of high-speed tool steel, which will wear out after a long working time, resulting in the situation of continuous cutting. The utility model is made of high-speed tool steel as a whole, and a hard alloy blade 4 is embedded at the cutting edge. Such a moving knife has both the toughness of high-speed tool steel and the wear resistance of hard alloy steel. It will not wear out after a long working time, resulting in the situation of continuous cutting.

[0027] The utility model also discloses a gold sheet slicing structure, comprising the above-mentioned movable knife body 1, and also comprising a fixed knife 5, and a mounting frame 6 for mounting the fixed knife and the movable knife body 1. The mounting frame 6 is provided with a movable knife shaft 7 for driving the movable knife body 1, the handle portion 101 of the movable knife is provided with a cutting surface 9, the movable knife shaft 7 is provided with a clamping groove 8 clamped with the movable knife body 1, the clamping groove 8 and the cutting surface 9 cooperate, so that the movable knife body 1 is clamped in the clamping groove 8, the clamping groove 8 is provided so that the movable knife body 1 is not easy to loosen when working at high speed, the clamping groove 8 clamps the movable knife body, drives the movable knife body 1 to rotate, reduces the friction between the movable knife body 1 and the movable knife shaft 7, and reduces wear.

[0028] The movable knife shaft 7 of the movable knife body 1 is arranged on the knife handle 101, and the movable knife shaft 7 is arranged above the fixed knife 5. The movable knife body 1 is provided with a gold plate avoidance gap 10 at the transition between the knife handle 101 and the blade 102. When the movable knife is separated from the fixed knife, a space for passing the plate is provided between the avoidance gap and the fixed knife.

[0029] When slicing is required, the moving knife cooperates with the fixed knife to slice, and after slicing is completed, the moving knife is separated from the fixed knife to facilitate the feeding of the moving knife. An avoidance gap 10 for avoiding gold sheets is set so that larger gold sheets can pass under the moving knife. This design can reduce the length of the moving knife when embroidering large pieces, and the cutting knife is more stable. Because if the force arm is longer, the knife is not only easy to deform, but also the torque of the cutting knife will increase. The moving knife body 1 is set above the fixed knife 5. When slicing, the required rotation angle is smaller, reducing the load of the motor.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
