Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wire breakers, and particularly relates to a texturing wire breaker with an inclined cutting structure. Background Technique
[0002] In the production process of texturing wire, the wire needs to go through multiple processes, such as stretching, false twisting, etc. Due to various reasons, the wire may break or become too thin. If the wire breaker does not detect the wire break in time, the following problems may occur: (1) Production interruption. If the equipment is not stopped in time after the wire breaks, it may affect the subsequent processing procedures, resulting in the interruption of the entire production line and reducing production efficiency; (2) Product quality decline. The wire break may cause defects in some products, affecting the appearance and performance of the products; (3) Equipment damage. The undetected wire break may wind around the equipment, causing damage to the equipment and increasing the maintenance cost. If the wire breaker does not detect that the wire is too thin in time, the following problems will occur: (1) Equipment failure. If the wire diameter is uneven or exceeds the allowable range of the equipment, it may cause the production equipment to malfunction. For example, during the textile process, a wire with too large a diameter may block the nozzle or roller, affecting the normal operation of the equipment; a wire with too small a diameter may break under the action of tension, damaging the equipment components; (2) Reduced production efficiency. If the wire diameter is unqualified, it may be necessary to frequently adjust the equipment parameters or perform manual intervention, which will increase the production time and cost and reduce the production efficiency. In addition, if product quality problems occur due to unqualified diameter, rework or scrapping may be required, further affecting the production efficiency; (3) Increased difficulty in quality control. The unqualified wire diameter makes quality control more difficult. During the production process, it is necessary to perform inspections and adjustments more frequently to ensure that the product quality meets the requirements. This not only increases the workload of quality control but also may cause unqualified products to flow into the market due to untimely or inaccurate inspections.
[0003] Therefore, whether the wire breaks or is too thin, it will have a greater impact on subsequent production. Through the detection of the wire breaker, the detection of wire break and wire being too thin can be realized. Most of the existing wire breakers can usually only detect wire breaks and do not have the function of detecting wire being too thin. Some wire breakers with the function of detecting wire being too thin usually use straight knife heads to cut the too-thin wire, and the straight knife heads are prone to chipping of the knife edge, resulting in a significant reduction in service life.
[0004] For the above reasons, the utility model hopes to provide a texturing wire breaker with an inclined cutting structure. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] A broken wire cutter for texturized yarn with an oblique cutting structure includes a main body shell 1. A maintenance cover 2 is provided at the opening of the main body shell 1. The maintenance cover 2 is detachable, facilitating disassembly and maintenance. For easy installation, two fixed ears 3 are provided on the left outer wall and the right outer wall of the main body shell 1 respectively. Fixing screws are screwed into the fixed ears 3 to install and fix the device. A wire inlet notch 4 and a wire outlet notch 5 are respectively provided at the front end and the rear end of the main body shell 1. The texturized yarn enters from the wire inlet notch 4 and is led out from the wire outlet notch 5.
[0026] A wire-breaking cutter head 6 is provided at the bottom of the rear abdomen of the main body shell 1. The wire-breaking cutter head 6 includes a main rotating shaft 7, and both ends of the main rotating shaft 7 are rotatably connected to the left side wall and the right side wall of the main body shell 1 respectively. The right end of the main rotating shaft 7 penetrates through the right side wall of the main body shell 1, and a servo motor 8 is provided at the outer right side wall of the main body shell 1. The servo motor 8 is connected to the main rotating shaft 7. In order to protect the servo motor 8, a servo motor housing 9 is provided at the outer right side wall of the main body shell 1, and the servo motor 8 is installed inside the servo motor housing 9. An optoelectronic sensor 10 is provided at the bottom of the front abdomen of the main body shell 1. Corresponding to the position of the optoelectronic sensor 10, an optoelectronic reflector 11 is provided on the surface of the maintenance cover 2. The optoelectronic sensor 10 is electrically connected to the servo motor 8, and the detection signal of the optoelectronic sensor 10 is transmitted to the servo motor 8 to drive the servo motor 8 to work. A wiring duct 12 is provided at the outer right side wall of the main body shell 1. One end of the wiring duct 12 is connected to the servo motor housing 9, and the other end of the wiring duct 12 is connected to the optoelectronic sensor 10. The connecting wire between the optoelectronic sensor 10 and the servo motor 8 passes through the wiring duct 12.
[0027] A fixed blade holder 13 is provided at the main rotating shaft 7 of the wire-breaking cutter head 6. Three blade mounting grooves 14 are provided on the blade holder 13. A V-shaped blade 15 is installed along the groove wall of the blade mounting groove 14 in the blade mounting groove 14, and the cutting edge of the V-shaped blade 15 is V-shaped. The cutting edge of the V-shaped blade 15 is in a closed-mouth shape. As the wire-breaking cutter head 6 rotates, the wire will slide to the narrow opening of the V-shaped blade 15, making it easier to cut the textured yarn. In order to prevent the wire-breaking cutter head 6 from cutting the textured yarn non-targetedly, the initial position of the wire-breaking cutter head 6 needs to ensure that the blade holder 13 is completely flat. Therefore, the closest distance from the main rotating shaft 7 to the optoelectronic sensor 10 is greater than the length of the blade holder 13. Similarly, in order to be able to perform an oblique cut, that is, to avoid a large angular rotation of the wire-breaking cutter head 6, the closest distance from the main rotating shaft 7 to the maintenance cover 2 is less than the length of the blade holder 13. This setting limits the maximum angular rotation of the wire-breaking cutter head 6 by the maintenance cover 2.
[0028] When using this device, the textured yarn is introduced from the wire inlet notch 4 and further exported from the wire outlet notch 5. In the initial state, the blade holder of the wire-breaking cutter head 6 is completely flat, and the optoelectronic sensor 10 works normally. The optoelectronic sensor 10 emits an optoelectronic signal, and after being reflected by the optoelectronic reflector 11, the optoelectronic signal is recovered to detect whether the textured yarn is broken and whether its diameter does not meet the standard. When the diameter of the textured yarn is too thin, the servo motor 8 works, and the wire-breaking cutter head 6 rotates to the maximum angle to cut the substandard textured yarn.
[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
