Description

Technical Field

[0001] This utility model relates to the field of weaving technology, specifically to a device for detecting changes in yarn width on a forming machine. Background Technology

[0002] After the fiber bundle passes through the first feeder of the forming machine, its width changes. To ensure the quality of the fiber bundle, it is necessary to detect the width change data to analyze and characterize the stability and consistency of the width change. Using general sensors or contact measurement methods to detect the width change is not only inefficient and inaccurate, but also easily affects the movement of the ribbon. Directly using a camera for imaging is problematic because the ribbon on the forming machine is at a certain height and in a high-speed, tilted state. Therefore, it is difficult to control a stable height and angle for direct camera shooting, resulting in inaccurate and unstable image capture, affecting the detection accuracy. Thus, there is an urgent need for a device that can accurately, quickly, and efficiently detect the width data of the fiber bundle. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a device for detecting the width and width changes of filaments on a molding machine.

[0018] The following are the symbol labels: 100 Base, 110 Vertical Guide Rail, 120 Vertical Slider, 130 Stand, 140 Rotary Adjustment Disc, 151 Monitor, 152 Alarm Light, 153 Barcode Scanner, 154 Control Panel, 155 Casters, 156 Push-Pull Handle, 200 Backlight Assembly, 210 Backlight Panel, 220 Positioning Axis, 300 Camera Assembly, 400 Ribbon. Detailed Implementation

[0019] The embodiments of this utility model are described in detail below, with reference to Figure 1 and Figure 2 The present invention provides a device for detecting the width variation of a ribbon 400 on a forming machine, comprising a base 100, a backlight assembly 200, and a camera assembly 300. The backlight assembly 200 and the camera assembly 300 are both mounted on the base 100, and are respectively positioned on both sides of the ribbon 400. The camera assembly 300 is capable of taking pictures of the ribbon 400 that quickly passes through the side of the backlight assembly 200.

[0020] This device is equipped with a backlight assembly 200 and a camera assembly 300, which are positioned opposite each other on both sides of the ribbon 400. The backlight assembly 200 can clearly display the edges of the ribbon 400, and the camera assembly 300 takes pictures of the ribbon 400 as it quickly passes through the side of the backlight assembly 200 to obtain an overall outline of the ribbon 400. This allows for accurate, fast, and efficient detection of the width data of the ribbon 400, which is then used to analyze and characterize the stability and consistency of the width variation of the ribbon 400.

[0021] Furthermore, the backlight assembly 200 includes a backlight plate 210 and positioning shafts 220 rotatably connected to both sides of the backlight plate 210, with the two positioning shafts 220 distributed along the movement direction of the ribbon 400. The backlight plate 210 uses a high-brightness white backlight, which allows the edges of the ribbon 400 to be presented more clearly, enabling the camera assembly 300 to capture a clearer and more precise outline. The two positioning shafts 220 are stainless steel optical shafts and are rotatably connected to both sides of the backlight plate 210. While positioning the ribbon 400 to ensure a stable positional relationship between the ribbon 400 and the backlight assembly 200 and camera assembly 300, they also guide the movement of the ribbon 400 and prevent scratching, thus not affecting the operation and quality of the ribbon 400. Specifically, the camera assembly 300 can be a common industrial camera.

[0022] Furthermore, the base 100 is equipped with a monitor 151, mouse, keyboard, alarm light 152, barcode scanner 153, etc. The monitor 151 can display the detection data in real time, the mouse and keyboard can be used by the operator, the alarm light 152 can sound an alarm when the equipment malfunctions, and the barcode scanner 153 is used to scan product batch information for data traceability. Furthermore, an operating table 154 is rotatably connected to the base 100. The operating table 154 can be opened or closed relative to the base 100. When opened, it facilitates the placement of the mouse, keyboard, etc., for operation; when closed, it can be concealed against the base 100. Furthermore, the base 100 is also equipped with a counterweight base to prevent the equipment from tipping over. Casters 155 are also provided at the bottom of the base 100 for moving the entire device. A push-pull handle 156 can also be provided on the side of the base 100 for the operator to push and pull the entire device.

[0023] Furthermore, the height and angle of both the backlight assembly 200 and the camera assembly 300 are adjustable. During inspection, operators can adjust the backlight assembly 200 and the camera assembly 300 to the required inspection height according to actual inspection needs, and adjust the angles of the backlight assembly 200 and the camera assembly 300 accordingly based on the tilt angle of the ribbon 400. This ensures that the positions of the backlight assembly 200, the camera assembly 300, and the ribbon 400 are accurate and stable, allowing for better and more precise image acquisition of the ribbon 400 and improving inspection accuracy. The following descriptions are provided through Examples 1 to 4:

[0024] Example 1

[0025] This embodiment provides a device for detecting changes in the width of a ribbon on a forming machine. Both the backlight assembly 200 and the camera assembly 300 are vertically movably connected to the base 100, thereby adjusting their heights and the positional relationship between the ribbon 400 and the backlight assembly 200 and camera assembly 300. Specifically, the base 100 is provided with a vertical guide rail 110, on which a vertical slider 120 is vertically movably connected. A support rod 130 is connected to the vertical slider 120, and the backlight assembly 200 and camera assembly 300 are respectively mounted at both ends of the support rod 130. When the vertical slider 120 moves along the vertical guide rail 110, it drives the backlight assembly 200 and camera assembly 300 to move vertically. More specifically, the vertical movement of the vertical slider 120 can be achieved by gear transmission, lead screw transmission, belt transmission, etc., and can be adjusted manually or electrically.

[0026] Of course, in some other embodiments, the backlight assembly 200 and the camera assembly 300 may also move vertically relative to the base 100.

[0027] Example 2

[0028] This second embodiment provides a device for detecting changes in the width of a ribbon on a forming machine. Both the backlight assembly 200 and the camera assembly 300 are rotatably connected to the base 100, thereby adjusting their angles and the positional relationship between the ribbon 400 and the backlight assembly 200 and camera assembly 300. Specifically, a rotating adjustment disk 140 is rotatably connected to the base 100, and a support rod 130 is connected to the rotating adjustment disk 140. The backlight assembly 200 and the camera assembly 300 are respectively mounted at both ends of the support rod 130. When the rotating adjustment disk 140 rotates, it drives the backlight assembly 200 and the camera assembly 300 to rotate together. More specifically, the rotation of the rotating adjustment disk 140 can be adjusted manually, for example, by using a tightening screw structure. Loosening the screw allows the rotating adjustment disk 140 to be rotated, and tightening it after adjustment fixes the rotating adjustment disk 140 in its current position. The adjustment can also be made electrically. For example, a rotary motor can be used to drive the rotary adjustment disk 140. After adjusting to the appropriate angle, the motor stops rotating, and the rotary adjustment disk 140 can be fixed in the current position.

[0029] Of course, in some other embodiments, the backlight assembly 200 and the camera assembly 300 may also rotate relative to the base 100.

[0030] Example 3

[0031] This embodiment provides a device for detecting changes in the width of a filament on a forming machine. Both the backlight assembly 200 and the camera assembly 300 are vertically movable and rotatably connected to the base 100. Specifically, the base 100 has a vertical guide rail 110, on which a vertical slider 120 is vertically movable. A rotating adjustment disk 140 is rotatably connected to the vertical slider 120, and a support rod 130 is connected to the rotating adjustment disk 140. The backlight assembly 200 and the camera assembly 300 are respectively mounted at both ends of the support rod 130. When the vertical slider 120 moves, it can drive the rotating adjustment disk 140, the support rod 130, the backlight assembly 200, and the camera assembly 300 to move vertically together, thereby adjusting the height. When the rotating adjustment disk 140 rotates, it can drive the support rod 130, the backlight assembly 200, and the camera assembly 300 to rotate together, thereby adjusting the angle.

[0032] Of course, in some other embodiments, the backlight assembly 200 and the camera assembly 300 can also move and rotate independently to adjust their height and angle respectively, which will not be elaborated here.

[0033] Example 4

[0034] This fourth embodiment provides a device for detecting the width variation of a filament on a forming machine. The difference between this device and the third embodiment is that both the backlight assembly 200 and the camera assembly 300 can be moved and adjusted along the length of the support rod 130. Simultaneously, both the backlight assembly 200 and the camera assembly 300 can rotate relative to the support rod 130. Therefore, the backlight assembly 200 and the camera assembly 300 can be simultaneously moved vertically and rotated, or they can move or rotate separately along the support rod 130. Various adjustment methods can be used to adjust the height and angle of the backlight assembly 200 and the camera assembly 300. This allows for adjustment not only of the position between the backlight assembly 200 and the camera assembly 300, but also of the position between the backlight assembly 200 and the camera assembly 300 and the ribbon 400, further improving detection accuracy. The movement and rotation structure of the backlight assembly 200 and the camera assembly 300 on the support rod 130 can also employ a combination of guide rails, sliders, and a rotating disk, which will not be elaborated upon here.
