Description

Technical Field

[0001] The present invention relates to the technical field of wire-taking equipment, and more particularly to a self-locking and self-resetting wire hooking and breaking mechanism, a wire-taking device and a continuous wire-taking machine. Background Art

[0002] In the production and processing of tin wire extruders, wire annealing machines or other linear materials, the traditional production of finished shafts faces a series of challenges. These challenges mainly come from the winding link in the production process, especially the conversion process from the output end of the production equipment to the final finished shaft.

[0003] In traditional production methods, linear materials (such as tin wire) are usually wound onto larger spools on a host machine (such as a tin wire extruder). This step is mainly to facilitate the transportation and temporary storage of materials. However, these larger spools cannot be used directly as final finished shafts because they usually do not meet the actual needs of customers or subsequent processing requirements.

[0004] Therefore, these larger spools need to be transferred to the next process - the sub-winding machine, where the materials on these spools will be rewound into smaller finished spools to meet the actual needs of customers. This process not only increases production time and cost, but also reduces production efficiency.

[0005] Since the wire winding operation needs to be performed twice on two different devices (one is winding onto the revolving shaft on the upper computer, and the other is winding onto the finished product shaft on the sub-winding machine), the production process is prolonged, the floor space is increased, and the overall production efficiency is reduced. At the same time, additional cutting equipment may be required during the wire winding process to cut the wire, which increases the complexity of the overall device.

[0006] Therefore, how to provide a wire taking-up machine that can optimize the production site, save equipment, realize integrated winding and cutting, break the wire on one side and hook the wire on the other side in one action, and realize continuous winding, is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0007] In view of this, the present invention provides a self-locking and self-resetting wire hook and wire breaking mechanism, a wire taking-up device and a continuous wire taking-up machine, aiming to fill the blank of directly winding finished products.

[0008] In order to achieve the above object, the present invention adopts the following technical solution:

[0009] A self-locking and self-resetting hook and wire breaking mechanism, comprising:

[0010] An outer sleeve, wherein the inner side wall of the outer sleeve has a protrusion protruding radially inward, and a conical surface is formed on one side of the protrusion;

[0011] A wire hooking and breaking rod, the wire hooking and breaking rod passes through and is slidably connected to the inner side of the outer sleeve, the outer side wall of the wire hooking and breaking rod has a radially protruding stopper, and the stopper limits the wire hooking and breaking rod from sliding on the inner side of the outer sleeve; the outer side coaxial sleeve of the wire hooking and breaking rod is provided with a first spring, and the first spring is pressed tightly between the stopper and the stepped surface of the protruding portion away from the conical surface; the two ends of the wire hooking and breaking rod are respectively formed with a clamping cutting portion and a protrusion;

[0012] A sliding sleeve, wherein the sliding sleeve is arranged on the outside of the wire hook and wire breaking rod, and a plurality of balls are embedded in the side wall of one end of the sliding sleeve located inside the outer sleeve, and the two sides of each of the balls are respectively in contact with the outer side wall of the wire hook and wire breaking rod and the conical surface, so that the conical surface forms pressure on the balls, and the balls press the wire hook and wire breaking rod, and when the sliding sleeve slides in the direction away from the conical surface, the pressure on the wire hook and wire breaking rod is released.

[0013] Through the above technical scheme, the present invention discloses a self-locking and self-resetting wire hook and wire breaking mechanism. Under the action of external force, the wire hook and wire breaking rod moves axially inside the outer sleeve, so that the clamping and cutting part moves to the inner side of the outer sleeve to achieve clamping and cutting of the wire material. The conical surface generates a clamping pressure on the wire hook and wire breaking rod through the ball, so that the wire hook and wire breaking rod can be automatically locked when subjected to external force to prevent the linear material from falling off; the first spring is tightly pressed between the gear rod and the conical surface, providing a reset force for the wire hook and wire breaking rod. When the sliding sleeve slides in the direction away from the clamping and cutting part, the pressure on the wire hook and wire breaking rod is released, and the wire hook and wire breaking rod can be automatically reset. The structural setting action can simultaneously achieve the effect of breaking the wire on one side and hooking the wire on the other side at one time, without the need to use additional tools, reducing the complexity of the equipment and improving work efficiency.

[0014] Preferably, in the above-mentioned self-locking and self-resetting hook wire breaking mechanism, an inner sleeve is coaxially arranged inside the outer sleeve, the inner sleeve is axially restricted inside the outer sleeve by a locking nut connected to the outer sleeve, the outer wall of the inner sleeve is formed with a first shaft section, a second shaft section and a third shaft section with successively decreasing outer diameters, the inner wall of the first shaft section is formed with the conical surface, the outer wall of the second shaft section is provided with a sliding groove corresponding to the shift rod, the first spring is sleeved on the outer side of the second shaft section and pressed against the stepped surface formed by the shift rod and the first shaft section and the second shaft section; the end of the third shaft section away from the second shaft section passes through the locking nut and extends to the outer side of the outer sleeve. This design not only improves the stability and reliability of the mechanism, but also makes the fit between the components tighter, reducing the occurrence of wear and failure.

[0015] Preferably, in the above-mentioned self-locking and self-resetting hook and wire breaking mechanism, the hook and wire breaking rod has the clamping and cutting portion at one end that cooperates with the third shaft section, and has the protrusion at the other end, and rollers are rotatably connected on both sides of the protrusion. By installing rollers on both sides of the protrusion, the friction resistance during the movement is reduced, and the design of the rollers also makes the protrusion smoother when cooperating with the turntable and other components, reducing the possibility of jamming and wear.

[0016] Preferably, in the above-mentioned self-locking and self-resetting hook and wire breaking mechanism, the outer wall of the sliding sleeve has a radially protruding annular retaining rib, and the outer wall coaxial sleeve is provided with a second spring, the second spring is pressed tightly between the annular retaining rib and the end face of the outer sleeve away from the conical surface; the end of the sliding sleeve away from the ball extends to the outside of the outer sleeve, and is fixed with a reset ring. By arranging the annular retaining rib and the second spring on the sliding sleeve, the automatic reset function of the sliding sleeve is realized, and by pulling the reset ring, the sliding sleeve is driven to move in a direction away from the clamping cutting part, so that the conical surface no longer produces a pressing force on the ball, and the pressure on the hook and wire breaking rod is released. It should be pointed out that the elastic force of the second spring is much greater than the elastic force of the first spring, and the elastic force of the second spring is greater than the friction force of the ball.

[0020] Preferably, in the above-mentioned wire-taking device, the number of the wire-taking mechanism, the wire hanging column, the second gear and the self-locking and self-resetting wire hooking and breaking mechanism are all multiple and the number is the same.
