Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a sensor support. Background Art

[0002] A sensor is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. The sensors used for yarn feeders on the market include Hall sensors. The tension of the yarn is not constant during the conveying process. The Hall sensor detects the tension of the yarn through the change of magnetic force. The principle is that the tension of the yarn increases or decreases, resulting in different tightness of the yarn. The force exerted by the yarn through the sensor is also different, which changes the distance between the original parts on the sensor, so the magnetic force also changes.

[0003] The weight of yarn is relatively light, and the components of existing sensors on the market are relatively heavy, so they may not be able to detect the yarn tension accurately, resulting in large errors. Utility Model Content

[0021] 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.

[0022] like Figure 1-3 As shown, a sensor support includes a spring piece 1 and a support 2 installed at one end of the spring piece 1. As shown, a mounting groove 3 is provided at the bottom of the support 2. The spring piece 1 is inserted into the mounting groove 3. A clamping part 4 is provided between the mounting groove 3 and the spring piece 2. The spring piece 1 and the support 2 are detachably connected through the clamping part 4. The spring piece 1 is installed in the mounting groove 3. The side wall of the mounting groove 3 abuts against the end of the spring piece 1 to prevent the spring piece 1 from bouncing up and down during use, causing the support 2 to move. A contact block 5 is provided on the top of the support 2. The interior of the support 2 is hollow, which further reduces the weight of the support 2.

[0023] like Figure 3As shown, the present invention is installed on the sensor of the yarn feeder. When the yarn feeder is transporting the yarn, the yarn is above the contact block 5 and forms friction with the contact block 5 to generate a downward pressure. When the machine is working, the motor rotates to make the yarn continuously pass through the contact block 5. The speed of the motor rotation will affect the tension of the yarn. If the motor speed is slow, the tension of the yarn is small, the yarn will sag slightly, driving the support 2 to move downward, and the spring 1 to move downward; on the contrary, if the motor speed is fast, the tension of the yarn is large, the yarn will be straightened and move slightly upward, and the support 2 will also move upward under the action of the rebound force of the spring 1. The sensor usually uses a Hall sensor, which generates different magnetism through the change of the distance of the support 2, thereby generating different electrical signals to be transmitted to the internal control panel, so that the yarn tension is always maintained at a fixed value. Since the weight of the yarn is light, the lighter the weight of the present invention, the higher the detection accuracy.

[0024] The contact block 5 shown includes an arc-shaped contact block, preferably a two-fifths circle shape. The arc-shaped design ensures the stability of the yarn passing through. The two-fifths circle shape can ensure sufficient curvature. Compared with the completed circle, the two-fifths circle also greatly reduces the weight of the contact block 5, making the accuracy of yarn detection more accurate.

[0025] The illustrated clamping portion 4 includes a clamping block 6 protruding from the mounting groove 3 and a clamping hole 7 located at one end of the spring sheet. The clamping block 6 is matched with the clamping hole 7. When the installation is completed, the clamping block 6 is embedded in the clamping hole 7, which is convenient for installation and replacement.

[0026] The support 2 shown is provided with at least two support columns 8, which are designed to be transverse, and preferably the two support columns 8 are distributed at the upper and lower ends to ensure sufficient supporting force and prevent the support 2 from being hollow and easily deformed. The two support columns 8 can also avoid being too heavy.

[0027] The spring piece 1 shown includes a fixed end 9 at one end and a movable end 10 at the other end, the support 2 is installed at the end of the movable end 10, the fixed end 9 is provided with a fixing hole 11, the fixed end 9 is fixed to the sensor through the fixing hole 11, and the support 2 is driven to move up and down through the movable end 10. In addition, an arc-shaped hollow portion 12 is provided at the end of the fixed end 9 to reduce the weight of the spring piece 1 and save costs.

[0028] As shown, recessed portions 13 are provided on both sides of the connection between the fixed end 9 and the movable end 10, and at least one through hole 14 is provided on the spring piece 1. The design of the recessed portion 13 and the through hole 14 further reduces the weight of the spring piece 1 and further ensures the accuracy of yarn detection.

[0029] The contact block 5 shown includes a ceramic contact block. Since the contact block 5 is in a state of friction with the yarn for a long time, a ceramic material is used. The ceramic material has good wear resistance and high temperature resistance, high hardness and is not easy to deform, thereby avoiding an increase in the error of the sensor detecting the tightness of the yarn.

[0030] The spring piece 1 shown includes a metal spring piece, which has good toughness, relatively stable contact, strong conductivity, stable rebound and good hand feel.

[0031] The support 2 shown comprises a plastic support, which has a low cost and the plastic material is light in weight, which further reduces the weight and increases the accuracy of the sensor in detecting the tightness of the yarn.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
