[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention.

[0028] Reference Figure 1-4 One embodiment of the present invention provides a calibration device for a fabric length measuring instrument, comprising the following parts:

[0029] Connecting part 1 is a mechanical component, which is used to be fixedly connected to a cloth winding machine or a fabric length measuring instrument (hereinafter referred to as the measuring instrument), and ultimately to maintain a relative fixation with the setting position of the measuring instrument;

[0030] The rotating part 2 is rotatably provided on the connecting part 1, and after contacting the rubber wheel on the measuring instrument, it can be synchronously operated together with the rubber wheel on the measuring instrument, and the rotating part 2 is provided with a driving force;

[0031] An encoder 3 connected to the connecting portion 1 and drivingly connected to the rotating portion 2;

[0032] Based on the above, in the process of realizing the calibration of the measuring instrument of the present invention, the connecting part 1 is fixedly installed on the fabric measuring surface of the cloth winding machine. In the prior art, the fabric length measuring instrument consists of a rubber wheel provided on the cloth winding machine and a sensor connected to the rubber wheel. During the movement of the fabric, the rubber wheel is driven to rotate, so that the length of the fabric passing through the machine is determined by detecting the rotation amplitude of the rubber wheel by the sensor. During the calibration of the present invention, the rotating part 2 contacts the rubber wheel, and the rotating part 2 automatically rotates to drive the rubber wheel to rotate. The rotation amplitude of the rotating part 2 is collected by the encoder 3 to determine the distance swept by the circumference of the rotating part 2. When the distance reaches a predetermined value, the value displayed by the sensor on the measuring instrument is synchronously observed to determine the indication error of the measuring instrument to complete the calibration process. The structure of the present invention is relatively simple. Through the action of a connecting part 1, multiple mechanical components are combined into a whole, so that when multiple mechanical components are installed on the silk cloth machine, only the installation of the connecting part 1 is completed, thereby ensuring that the setting process of the present invention on the cloth winding machine is simple and fast, and simplifying the entire calibration process. At the same time, the present invention can be more convenient to carry.

[0033] Further, refer to Figure 5 Regarding the data measurement process during the calibration process, specifically, the utility model also includes a display, a value acquisition element and a computer. The value acquisition element is used to collect the real-time display value of the sensor on the measuring instrument and is connected to the computer, so that the value of the measuring instrument is transmitted to the computer for processing. The computer here is preferably portable, such as a laptop computer. An electrical signal connection is established between the display and the encoder 3, so that the value of the encoder 3 can be collected in real time during the data measurement process. Therefore, the utility model can realize online calibration and improve the convenience of the process.

[0034] Further, refer to Figure 5 The numerical value acquisition component includes a camera, through which the measurement value of the measuring instrument can be observed in real time.

[0035] Further, refer to Figure 5 Regarding the connection method between the encoder 3 and the display, specifically, the utility model also includes a single-chip microcomputer control system. The encoder 3 and the display are both connected to the single-chip microcomputer control system. The single-chip microcomputer control system can obtain the pulse count of the encoder 3, thereby transmitting the data to the display. Therefore, it can display the scanning path parameters of the roller in real time and the rotation speed of the roller at the same time.

[0036] Further, refer to Figure 1-2As for the driving force configuration of the roller, specifically, the utility model further includes a driving element, and the rotating part 2 can maintain rotation at a predetermined amplitude through the driving element, that is, the sweeping path of the roller is controlled to be exactly the standard number of meters, so that when the roller rotates to the target number of circles, it automatically stops. At this time, the parameters of the measuring instrument can be directly observed. This design avoids the roller running too long during the working process, making the capture of data during the calibration process more convenient and more accurate.

[0037] Further, refer to Figure 1 and Figure 2 The driving element includes a stepper motor 4, which is connected to the single-chip microcomputer control system. Therefore, by manually setting the single-chip microcomputer control system, the single-chip microcomputer control system can automatically generate pulses to the stepper motor 4, thereby controlling the stepper motor 4 to rotate at a predetermined amplitude, that is, it automatically stops when it reaches a predetermined number of turns, and the rotation speed can also be effectively controlled.

[0038] Further, refer to Figure 1-4 Regarding the connection method between the connecting part 1 and the cloth winding machine, specifically, the connecting part 1 includes a connecting seat 101, a connecting hook 102 and a bracket 103. The bracket 103 is fixedly connected to the connecting seat 101, and the rotating part 2 is arranged on the bracket 103. The connecting hook 102 is adjustably connected to the connecting seat 101, and a bite area is formed between the connecting hook 102 and the connecting seat 101. When the connection between the connecting hook 102 and the connecting seat 101 is adjusted, the gap in the bite area can be adjusted, so that the fixed shaft on the silk cloth machine can be tightened to achieve the fixation of the entire structure on the machine. This structure ensures that the connection process is simple, convenient and easy to operate.

[0039] Further, refer to Figure 3 Regarding the adjustment method between the connecting hook 102 and the connecting seat 101, specifically, the connecting hook 102 and the connecting seat 101 are connected by a bolt assembly. The bolt adjustment method is simple and easy to operate, and has low manufacturing cost.

[0040] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
