Description

Technical Field

[0001] This utility model belongs to the technical field of textile industry and related equipment, and in particular relates to an anti-broken thread mechanism for a braiding machine. Background Technology

[0002] Braiding machines are commonly used equipment in the textile industry. They are suitable for various raw materials, including nylon multifilament, polypropylene filament, polypropylene, polyester, nylon, PP, low-elasticity yarn, high-elasticity yarn, and cotton yarn. The anti-breakage mechanism is an important auxiliary device used in braiding machines. It can effectively reduce or prevent yarn breakage caused by various reasons during the braiding process, and plays a significant role in the continuous movement of the yarn and the quality of the braiding.

[0003] A search revealed that publication number CN117779341A, with an application date of 2023.12.08, discloses an anti-breakage mechanism for a braiding machine, including a base and two side plates movably disposed on both sides of the base. A lower elastic structure is provided between the two side plates and the base. A top seat is fixedly connected to the top of the two side plates relative to the top of the base. A drum is rotatably mounted between the two side plates via a rotating shaft. Multiple elastic guide roller assemblies are provided on the surface of the drum.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. Existing anti-broken yarn mechanisms used in braiding machines protect the yarn through a simple buffer structure. However, when the yarn moves, it generates static electricity and adheres to the surface of the guide roller, which can easily cause the yarn to entangle and break.

[0006] 2. Existing anti-breakage mechanisms for braiding machines lack dust protection during use, making them susceptible to interference from dust and lint during yarn breakage detection, thus failing to accurately determine the extent of yarn breakage. Therefore, we provide an anti-breakage mechanism for braiding machines to solve the aforementioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a yarn breakage prevention mechanism for a braiding machine. By setting an electrostatic elimination component, the static electricity on the surface of the yarn is neutralized, thereby eliminating static electricity and reducing yarn adhesion. In addition, by using a photoelectric sensor body, air duct and reflector, dust and lint in the environment are removed, improving the accuracy of yarn breakage detection.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a yarn breakage prevention mechanism for a braiding machine, including a top seat and connecting rods fixed at the front and rear ends of its bottom. An electrostatic elimination component is provided on one side above the top seat. A photoelectric sensor body is installed on the front end face of the top seat by bolts. Air ducts are installed on the upper sides of both sides of the photoelectric sensor body. A reflector is installed on the rear end face of the top seat by bolts. The photoelectric sensor body and the reflector are symmetrically arranged.

[0010] The static elimination assembly includes a hollow tube disposed on one side above the top seat, and a second side plate rotatably mounted on the front and rear ends of the hollow tube, with a second rotating shaft installed below between adjacent second side plates.

[0011] The present invention is further configured such that extrusion grooves are provided on both sides of the interior of the top seat, a pressure plate is fixed at the bottom of the connecting rod, and a base is provided directly below the top seat, with a rectangular hole opened inside the base.

[0012] The present invention is further configured such that guide rods are fixedly provided at both ends of the front and rear sides of the inner side of the rectangular hole, and springs are sleeved on the outer wall of the guide rods, with the pressure plate located inside the rectangular hole.

[0013] The present invention is further configured such that the pressure plate is slidably sleeved on the outer wall of the guide rod, the spring is located between the pressure plate and the inner wall of the rectangular hole, and a guide roller is provided on the other side above the top seat.

[0014] The present invention is further configured such that the front and rear ends of the guide roller are rotatably mounted in bearings on adjacent first side plates, and a first rotating shaft is installed below between the front and rear adjacent first side plates.

[0015] The present invention is further configured such that the first rotating shaft is rotatably mounted in the bearing inside the extrusion groove, and a torsion spring is sleeved on the outer wall of the first rotating shaft, the torsion spring being located inside the extrusion groove.

[0016] The present invention is further configured such that the second rotating shaft is rotatably mounted in the bearing inside the extrusion groove, and a torsion spring is sleeved on the outer wall of the second rotating shaft, and the torsion spring is located inside the extrusion groove.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model neutralizes static electricity on the yarn surface by setting up an electrostatic elimination component, thereby eliminating static electricity and reducing yarn adhesion. It solves the problem that existing anti-breakage mechanisms used in braiding machines protect the yarn with a simple buffer structure, but the yarn generates static electricity and adheres to the guide roller surface during movement, which can easily cause yarn entanglement and breakage.

[0020] 2. This utility model, by setting up a photoelectric sensor body, air duct and reflector, uses the air duct on the photoelectric sensor body to blow away dust and lint from the surrounding environment during yarn operation.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

[0031] Please see Figures 1 to 5 This utility model is a yarn breakage prevention mechanism for a braiding machine, including a top seat 100 and connecting rods 102 fixed at the front and rear ends of the bottom sides. An electrostatic elimination component 200 is provided on the upper side of the top seat 100. The electrostatic elimination component 200 includes a hollow tube 201 provided on the upper side of the top seat 100 and a second side plate 202 rotatably installed at the front and rear ends of the hollow tube 201. A second rotating shaft 202a is installed below between adjacent second side plates 202.

[0032] Specifically, the top seat 100 has extrusion grooves 101 on both sides inside, a pressure plate 102a is fixed to the bottom end of the connecting rod 102, and a base 103 is provided directly below the top seat 100. A rectangular hole 103a is opened inside the base 103. Guide rods 104 are fixed to both the front and rear ends of the rectangular hole 103a. Springs 104a are sleeved on the outer wall of the guide rods 104. The pressure plate 102a is located inside the rectangular hole 103a. The pressure plate 102a is slidably sleeved on the outer wall of the guide rods 104. The springs 104a are located between the pressure plate 102a and the inner wall of the rectangular hole 103a. A guide roller 105 is provided on the other side above the top seat 100. The front and rear ends of the guide roller 105 are rotatably mounted in bearings on the adjacent first side plates 106. A first rotating shaft 106a is installed below the 06; the first rotating shaft 106a is rotatably installed in the bearing inside the extrusion groove 101, and a torsion spring 106b is sleeved on the outer wall of the first rotating shaft 106a, and the torsion spring 106b is located inside the extrusion groove 101; a second rotating shaft 202a is rotatably installed in the bearing inside the extrusion groove 101, and a torsion spring 106b is sleeved on the outer wall of the second rotating shaft 202a, and the torsion spring 106b is located inside the extrusion groove 101; air outlet strips 201a are evenly spaced along the circumference of the outer wall of the hollow tube 201, and an ion air bar 203 is provided inside the hollow tube 201. One end of the ion air bar 203 is connected to the high-pressure generator body 204, and air outlet holes 203a are arranged in an array from front to back on the outer wall of the ion air bar 203.

[0033] Furthermore, the connecting rod 102 connects the top seat 100 and the pressure plate 102a, serving as a connecting transmission mechanism. The hollow tube 201 can rotate between adjacent second side plates 202. The guide rod 104 limits and guides both the pressure plate 102a and the spring 104a. Under the elastic action of the spring 104a, it can buffer and protect the yarn when it is subjected to a downward force. Under the elastic action of the torsion spring 106b, it can buffer and protect the yarn when it is subjected to a force in the direction of movement. The high-voltage generator body 204 is existing technology, so it will not be described in detail here. The principle of the ion wind bar 203 is that it can generate a large number of air masses with positive and negative charges, which can neutralize the charge on the object in its ion radiation zone. When the object surface is negatively charged, it will attract the positive charge in the radiation zone. When the object surface is positively charged, it will attract the negative charge in the radiation zone, so that the static electricity on the object surface is neutralized, thus achieving the purpose of eliminating static electricity.

[0034] The operation process of this embodiment is as follows: When the braiding machine is in use, the yarn rests on the guide roller 105 and the outer wall of the hollow tube 201. During the tensioning process of the yarn, it applies a force in the direction of motion and a downward squeezing force to the guide roller 105 and the hollow tube 201. The guide roller 105 and the hollow tube 201, subjected to the force in the direction of motion, rotate around the first rotating shaft 106a and the second rotating shaft 202a respectively, and squeeze the torsion spring 106b, which plays a buffering role. The guide roller 105 and the hollow tube 201, subjected to the downward squeezing force, drive the top seat 100 to move down, and push the pressure plate 102a down through the connecting rod 102. The pressure plate 102a slides along the outer wall of the multiple guide rods 104. The compression spring 104a acts as a buffer, reducing the stress and tension on the yarn during operation and preventing yarn breakage. As the yarn moves across the surface of the hollow tube 201, the high-voltage generator body 204 is activated, and the ion bar 203 generates a large number of positively and negatively charged air masses. These air masses neutralize the charge on the yarn passing through its ion radiation zone. When the yarn surface is negatively charged, it attracts positive charges in the radiation zone, and when the yarn surface is positively charged, it attracts negative charges in the radiation zone. This neutralizes the static electricity on the yarn surface, achieving the purpose of eliminating static electricity and reducing yarn adhesion.

[0035] Example 2

[0036] Please see Figure 1 and Figure 2Based on Embodiment 1, the difference from the first embodiment is that a photoelectric sensor body 300 is provided. Air ducts 301 are installed on the upper side walls of both sides of the photoelectric sensor body 300. A reflector 302 is installed on the rear end face of the top seat 100 by bolts. The photoelectric sensor body 300 and the reflector 302 are symmetrically arranged. This solves the problem that the existing anti-broken yarn mechanism used in braiding machines lacks dustproof measures during use and is easily interfered with by dust and flying fluff when detecting yarn breakage, making it impossible to accurately determine the yarn breakage situation.

[0037] Furthermore, the photoelectric sensor body 300 and the reflector 302 are retroreflective type. The principle of the photoelectric sensor body 300 is based on the photoelectric effect, which converts the change of the measured quantity into a change of light signal. Then, with the help of photoelectric elements, the non-electric signal is further converted into an electrical signal. The photoelectric effect refers to the phenomenon that when light shines on an object, it can be regarded as a series of photons with a certain energy bombarding the object. At this time, the energy of the photons is transferred to the electrons, and the entire energy of a photon is absorbed by an electron at once. After the electrons receive the energy transferred by the photons, their state will change, causing the object irradiated by the light to produce a corresponding electrical effect. The duct 301 is connected to an external fan and is used to exhaust air to blow away dust and flying fluff.

[0038] The operation process of this embodiment is as follows: When the yarn moves between the guide roller 105 and the hollow tube 201, the photoelectric sensor body 300 irradiates the yarn with light. A series of photons with a certain energy bombard the yarn. At this time, the photon energy is transferred to the electron, and the entire energy of a photon is absorbed by an electron at one time. After the electron receives the energy transferred by the photon, its state will change, causing the yarn irradiated by the light to produce a corresponding electrical effect. The system monitors whether the yarn breaks during the movement and stops the machine in time for inspection. A duct 301 is set on the photoelectric sensor body 300. During the yarn operation, an external fan draws air out through the duct 301 to blow away dust and lint from the surrounding environment. The dustproof design avoids interference from lint and affects the yarn breakage monitoring effect.
