[0002] Textile thread break detection is an indispensable component of textile machinery and equipment. By detecting thread breakage and controlling the shutdown of textile machinery and equipment, the normal progress of subsequent textile operations can be ensured. There are many existing methods for textile thread break detection, but most of them are achieved through tension detection. Generally, an elastic tension is applied to the elastic part using the textile thread. When the elastic tension disappears, it is judged as a thread break to ensure that the thread break problem can be handled in time.

In addition, the strength of the yarn is weaker than that of ordinary yarn. The method of detecting the broken thread by applying elastic tension on the yarn is not reliable, but it is easy to increase the probability of broken thread, thus affecting product quality.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 and Figure 2 The utility model provides a technical solution: a textile machinery broken thread detection device, comprising a fixed block 1 and a fixed gear 2, the fixed gear 2 is rotatably mounted on the top of the fixed block 1, a movable groove 3 is provided on the surface of the fixed block 1 away from the lower half of the fixed gear 2, a movable block 4 is slidably mounted inside the movable groove 3, a moving gear 5 is rotatably mounted on one end of the moving block 4, the moving gear 5 and the fixed gear 2 are meshed with each other, a connecting rod 6 is fixedly mounted on the side of the fixed block 1, a detection block 7 is fixedly mounted on the end of the connecting rod 6 away from the fixed block 1, a warning light 8 is fixedly mounted on the top of the detection block 7, and a detection member for detecting whether the yarn is broken is provided in the detection block 7;

[0029] It also includes a moving component for moving the moving gear 5, and the moving component is located between the moving gear 5 and the fixed block 1. First, the yarn is placed between the fixed gear 2 and the moving gear 5, and the two are meshed together by the moving component to fix the yarn, and then the yarn passes through the interior of the detection block 7. This method allows the fixed gear 2 to drive the moving gear 5 to rotate to transport the yarn. Compared with the method of applying elastic tension to detect broken wire, the pressure intensity applied to the yarn is not large, and the friction between the yarn and it is relatively small, so it is less likely to break.

[0030] Furthermore, the detection component includes a detection slot 9 opened in the middle of the detection block 7, a detection light 10 is fixedly installed on the inner wall of the detection slot 9, and a photoelectric sensor 11 is fixedly installed on the side of the inner wall of the detection slot 9 away from the detection light 10. The photoelectric sensor 11 is electrically connected to the prompt light 8 and the fixed gear 2. When the photoelectric sensor 11 in the detection component finds that the yarn is broken, the prompt light 8 will be controlled to light up to remind the staff that the yarn is broken here, which is convenient for the staff to quickly locate it. At the same time, the fixed gear 2 can be controlled to stop running, and the broken yarn will be fixed to make it easier to find the yarn later.

[0031] Furthermore, the axis of the detection groove 9 is on the same axis as the meshing point between the mobile gear 5 and the fixed gear 2. The detection groove 9 is conical in shape, and the large end of the cone is close to the meshing point between the mobile gear 5 and the fixed gear 2. The design of the detection groove 9 can facilitate better passing of the yarn, and when the axis of the detection groove 9 is on the same axis as the meshing point between the mobile gear 5 and the fixed gear 2, the yarn can be kept parallel as much as possible to avoid excessive friction and the possibility of breakage.

[0032] Furthermore, the positions of the detection light 10 and the photoelectric sensor 11 are symmetrical to each other, and the photoelectric sensor 11 is electrically connected to the prompt light 8. The detection light 10 and the photoelectric sensor 11 can be used together to detect whether the line is broken.

[0033] See also Figures 3 to 5 The utility model provides a technical solution: further, the moving component includes a clamping block 12 fixedly mounted on the surface of the movable block 4, the clamping block 12 is clamped and mounted on the surface of the fixed block 1, and a plurality of clamping grooves 13 are provided on the surface of the fixed block 1 corresponding to the clamping position of the clamping block 12. A movable part for rotating the movable gear 5 is provided between the movable block 4 and the movable gear 5. By holding the clamping block 12, the clamping block 12 can be driven to move upward, and the movable gear 5 can be driven to move upward until it is meshed with the fixed gear 2, thereby fixing the yarn at the meshing point to facilitate the subsequent delivery of the yarn.

[0034] Furthermore, the length of the block 12 is greater than the width of the movable slot 3 , the surface of the block 12 is provided with anti-skid patterns, the block 12 and the slot 13 are adapted in size, and the block 12 can be snapped into the slot 13 at different positions.

[0035] Furthermore, the plurality of card slots 13 are arranged at equal distances.

[0036] Furthermore, the movable member includes a rotating shaft 14 rotatably mounted on one end of the movable block 4 away from the clamping block 12 , and one end of the rotating shaft 14 away from the movable block 4 is fixedly mounted on the axis of the moving gear 5 .

[0037] Furthermore, a rotary bearing is provided at the connection between the rotating shaft 14 and the movable block 4 .

[0038] Working principle: Before using the textile machinery thread breakage detection device, first place the yarn between the fixed gear 2 and the mobile gear 5, then hold the card block 12 to drive the card block 12 to move upward, and drive the mobile gear 5 to move upward until it meshes with the fixed gear 2. At this time, the fixed gear 2 and the mobile gear 5 fix the yarn at the meshing point, and then pass the other end of the yarn through the detection slot 9 for use, and then control the fixed gear 2 to rotate and drive the mobile gear 5 to rotate to transport the yarn. Compared with the method of applying elastic tension to the yarn to detect thread breakage, this method uses the method of mutual meshing between the fixed gear 2 and the mobile gear 5 when transporting the yarn, so that the pressure intensity applied to the yarn is not large, and the friction between the yarn and it is relatively small, and it is less likely to break.

[0039] It is worth mentioning that considering that the yarn is softer and more delicate than ordinary thread and is more prone to breakage, a warning light 8 and a detection component are provided for use. When the photoelectric sensor 11 in the detection component finds that the yarn is broken, the warning light 8 will be controlled to light up to remind the staff that the yarn is broken, which is convenient for the staff to quickly locate it. At the same time, the fixed gear 2 can be controlled to stop running. At this time, through the coordinated use of the fixed gear 2 and the movable gear 5, the broken yarn will be fixed by it, so that it is easier to find the yarn later.

[0040] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
