DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0020] The utility model is further described below in conjunction with embodiments.

[0021] Example: Refer to Figures 1 to 3 A chip thermistor sealing device comprises a bottom plate 1 and a braid 11. A bearing frame 2 is fixedly mounted on the top of the bottom plate 1. A turntable 3 and a winding disk 4 are rotatably connected to opposite sides of the bearing frame 2. A first motor 5 is fixedly mounted on one side of the bearing frame 2. The output end of the first motor 5 is fixedly connected to one end of the winding disk 4. The first motor 5 is started and the output end is fixedly connected to one end of the winding disk 4 to drive the winding disk 4 to rotate, so that the braid 11 can be wound up. An adjusting component is arranged inside the bearing frame 2.

[0022] The adjustment assembly includes a second motor 6 fixedly installed on the top of the bearing frame 2, and a slide groove 61 is provided on the opposite side of the inner wall of the bearing frame 2. The insides of the two slide grooves 61 are respectively rotatably connected with a screw rod 62 and a guide rod 63 fixedly installed, and the insides of the two slide grooves 61 are slidably connected with a moving seat 64. The two moving seats 64 are respectively threadedly connected to the screw rod 62 and slidably connected to the guide rod 63. A turntable 2 65 is rotatably connected between the two moving seats 64. The second motor 6 is started, and its output end is fixedly connected to one end of the screw rod 62, so that It drives the screw rod 62 to rotate at the same time, and is threadedly connected to the moving seat 64 through the screw rod 62, so that it drives the moving seat 64 to move up and down inside the slide groove 61. Since the turntable 2 65 is rotatably connected between the two moving seats 64, it can drive the turntable 2 65 to move at the same time. When the second motor 6 rotates forward, the turntable 2 65 moves upward, thereby reducing the tension of the braid 11. When the second motor 6 reverses, the turntable 2 65 moves downward, thereby increasing the tension of the braid 11. Corresponding adjustments are made according to needs.

[0023] A fixing plate 7 is fixedly installed on the opposite side of the top of the bearing frame 2, and a groove 71 is opened on the opposite side of the two fixing plates 7, and sliders 72 are slidably connected inside the two grooves 71, and springs 73 are fixedly installed between the two sliders 72 and the grooves 71, and a compacting wheel 74 is rotatably connected between the two sliders 72, and the outer side of the compacting wheel 74 contacts the outer surface of the braid 11 inside the winding disk 4, and the elastic force of the spring 73 pushes the sliders 72 on both sides to move downward, so that the two sliders 72 drive the compacting wheel 74 to move at the same time, so that the wound braid 11 can be compressed, and the elastic force of the spring 73 can be used to make it able to be adjusted accordingly according to the winding size of the braid 11.

[0024] The groove 71 and the slider 72 are both T-shaped, which play a limiting role to prevent the grooves 71 on both sides from being separated from the slider 72 during use, thereby improving the clamping effect of the equipment. The braid 11 is connected to the turntable 1 3, the turntable 2 65, and the winding disk 4 from left to right, and can drive the braid 11 to move so that it is finally wound around the outside of the winding disk 4 to complete the winding. A force gauge 8 is fixedly installed on one side of one of the moving seats 64 and at the lower end of the turntable 2 65. The force gauge 8 is electrically connected to the second motor 6. Pressure is applied to the force gauge 8 through the turntable 2 65. When the measured pressure value is less than the set value, the second motor 6 is controlled to reverse. Conversely, when the measured pressure value is greater than the set value, the second motor 6 is controlled to rotate forward.

[0025] The operating principle of this embodiment is as follows: when in use, the braid 11 is passed around the turntable 1 3 and the turntable 2 65 from left to right at a time, and is wound around the winding disk 4, and then the first motor 5 is started, and is fixedly connected to one end of the winding disk 4 through the output end, so that the winding disk 4 is driven to move at the same time, so that the braid 11 can be wound, and pressure is applied to the force measuring device 8 through the turntable 2 65. When the pressure value is less than the set value, the second motor 6 is controlled to reverse, and is fixedly connected to the screw rod 62 through the output end, so that the screw rod 62 is driven to move at the same time. The seat 64 is threadedly connected, so that the movable seat 64 drives the turntable 2 65 to move simultaneously, so that it squeezes the braid 11. Conversely, when the pressure value is greater than the set value, the second motor 6 is controlled to rotate forward, so that the turntable 2 65 moves upward, and corresponding adjustments can be made according to needs. At the same time, the elastic force of the spring 73 pushes the sliders 72 on both sides to move downward, so that the two sliders 72 drive the compacting wheel 74 to move simultaneously, thereby being able to compress the braid 11 inside the winding disk 4, and utilizing the elastic force of the spring 73 so that it can be adaptively adjusted according to the size of the braid 11.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
