DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] Reference Figure 1-5 A yarn tension detection device comprises a mounting plate 1, on which a tension detection structure 2 is provided, the tension detection structure 2 comprises an auxiliary component No. 1 3, on one side of the auxiliary component No. 1 3 a second auxiliary component 4 is provided, and between the auxiliary component No. 1 3 and the auxiliary component No. 2 4 a transmission member 6 is provided, the transmission member 6 is composed of two pulleys and a belt, on one side of the auxiliary component No. 2 4 a third roller 5 is provided, the third roller 5 is fixedly connected to the mounting plate 1, the auxiliary component No. 1 3 comprises an auxiliary component No. 1 301, on which a moving component 302 is provided, the auxiliary component No. 2 4 comprises an installation component 401, on which a power component 402 is provided.

[0029] Auxiliary component No. 1 301 includes two fixed plates 3011 fixedly connected to the mounting plate 1, and a cylinder 3012 is fixedly connected to the mounting plate 1, and the cylinder 3012 is located between the two fixed plates 3011. The cylinder 3012 is a prior art and will not be described in detail here. A roller No. 1 3013 is slidably connected between the two fixed plates 3011, and the bottom of the roller No. 1 3013 is fixedly connected to the output end of the cylinder 3012. A switch 3014 is provided on one side of one of the two fixed plates 3011, and the switch 3014 corresponds to the cylinder 3012.

[0030] The moving assembly 302 includes a rotating rod 3021 rotatably connected to the fixed plate 3011, a No. 1 gear 3022 is fixedly connected to the rotating rod 3021, a No. 1 row of teeth 3023 is slidably connected to the fixed plate 3011, a plurality of positioning rods 3024 are fixedly connected to one side of the No. 1 row of teeth 3023, the plurality of positioning rods 3024 are equidistantly arranged, and a pushing member 303 is provided on one side of the No. 1 row of teeth 3023.

[0031] The pushing member 303 includes a push plate 3031, which corresponds to the switch 3014. A fixing column 3032 is fixedly connected to one side of the push plate 3031. The fixing column 3032 corresponds to the positioning rod 3024, and the fixing column 3032 and the positioning rod 3024 are fixedly connected by a connecting member 3033. The connecting member 3033 consists of two circular rings and a cross bar. The two circular rings are respectively located at one end of the cross bar and are fixedly connected.

[0032] The mounting assembly 401 includes a pressure sensor 4011 fixedly connected to the mounting plate 1. The pressure sensor 4011 is a prior art and will not be described in detail herein. A fixing tube 4012 is fixedly connected to the pressure sensor 4011. A detecting end of the pressure sensor 4011 is fixedly connected to a connecting plate 4013, and the connecting plate 4013 is located in the fixing tube 4012. A spring 4014 is fixedly connected to the connecting plate 4013, and the other end of the spring 4014 is fixedly connected to a No. 2 roller 4015, and the No. 2 roller 4015 is located in the fixing tube 4012.

[0033] The power assembly 402 includes a side plate 4021 fixedly connected to the No. 2 roller 4015, one end of the side plate 4021 passes through the fixed cylinder 4012 and extends a portion thereof, a No. 2 row of teeth 4022 is fixedly connected to the side plate 4021, a rotating shaft 4023 is rotatably connected to the fixed cylinder 4012, the rotating shaft 4023 and the rotating rod 3021 are connected via a transmission member 6, a No. 2 gear 4024 is fixedly connected to the rotating shaft 4023, and the No. 2 gear 4024 is meshed with the No. 2 row of teeth 4022.

[0034] When in use, the yarn passes around the three rollers in sequence. The yarn will press the second roller 4015 downward, causing it to move downward. When the second roller 4015 moves downward, it will squeeze the spring 4014, causing the spring 4014 to deform. At this time, the force acting on the spring 4014 will be transmitted to the connecting plate 4013 and detected by the pressure sensor 4011, thereby detecting the tension of the yarn.

[0035] In this process, when the second roller 4015 moves downward, it will move with the side plate 4021, and the movement of the side plate 4021 will move with the second row of teeth 4022. Since the second row of teeth 4022 is meshed with the second gear 4024, it will cause the second gear 4024 to rotate, and then the shaft 4023 will rotate accordingly. Since the shaft 4023 and the rotating rod 3021 are connected by the transmission member 6, the rotating rod 3021 will rotate accordingly.

[0036] When the rotating rod 3021 rotates, the No. 1 gear 3022 rotates. Since the No. 1 gear 3022 is meshed with the No. 1 row of teeth 3023, the No. 1 row of teeth 3023 moves upward, and when the No. 1 row of teeth 3023 moves, the push plate 3031 moves. When the push plate 3031 moves, it encounters the switch 3014 and presses it. At this time, the cylinder 3012 is started, thereby pushing the No. 1 roller 3013 upward, thereby reducing the tension of the yarn and making the tension of the yarn within a specified range to prevent the yarn from breaking or stretching. Excessive force affects the quality of textiles. When the tension decreases, the pressure of the yarn on the No. 2 roller 4015 will decrease until the No. 2 roller 4015 moves upward under the elastic force of the spring 4014. At this time, the No. 2 gear 4024 and the No. 2 row of teeth 4022 will move in the opposite direction. When the No. 2 gear 4024 and the No. 2 row of teeth 4022 move in the opposite direction, the No. 1 gear 3022 and the No. 1 row of teeth 3023 will also move in the opposite direction. Therefore, the push plate 3031 will be separated from the switch 3014, and the output end of the cylinder 3012 will no longer move.

[0037] In this process, the distance that the push plate 3031 moves depends on the fluctuation range of the yarn tension, and the fluctuation range can be adjusted according to actual conditions. When adjusting the fluctuation range, the push plate 3031 is placed at a suitable height, and then the push plate 3031 and the fixed plate 3011 are fixed by the connecting piece 3033. At this time, the two rings on the connecting piece 3033 can be buckled on the positioning rod 3024 and the fixing column 3032 in turn.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
