Description

Technical Field

[0001] The present application relates to the technical field of blade detection, and in particular to a blade level detection mechanism. Background Art

[0002] Tobacco needs to be cut during the production process. Cutting can help adjust the size and shape of tobacco to make it more suitable for subsequent processing and use. At the same time, cutting also helps to improve the quality and uniformity of tobacco, ensuring that the tobacco products produced are of higher quality and reliability. The cutting blade needs to be inspected and maintained after multiple uses to ensure that it is not worn, bent or tilted to ensure the subsequent cutting quality.

[0003] Application No. 202320619704.1 discloses a blade detection mechanism, including a machine, a conveyor track, a blade, a lamp and a camera. The lamp emits light at a certain angle toward the blade, and then the light is reflected by the blade and transmitted to the camera. The camera then transmits the captured image to the system for judgment.

[0004] However, in use, there are the following defects:

[0005] Although laser irradiation detection is used to observe whether the blade edge is intact and level, the surface of some cutting blades is matte, which makes it impossible to collect the reflected light according to the preset reflection path, thus affecting the accuracy of the blade detection results. Utility Model Content

[0006] The purpose of the present application is to provide a blade level detection mechanism, which solves the problem raised in the background technology that although laser irradiation detection is used to observe whether the blade edge is intact and level, the surface of some cutting blades is matte, which makes it impossible to collect the reflected light according to the preset reflection path, thereby affecting the accuracy of the blade detection result.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a blade horizontal detection mechanism, comprising a base, a support frame, a side baffle, a sliding block and a blade body, wherein a No. 1 sliding groove is vertically opened on both sides of the top of the base, and the bottom of both sides of the support frame are horizontally slidably connected on the inner side of the No. 1 sliding groove, an electric push rod is fixedly installed below the center of the top of the support frame, the bottom of the electric push rod is fixedly connected to the center of the top of the cross plate, the left and right inner walls of the support frame are both provided with limiting grooves, and the two ends of the cross plate are vertically slidably connected on the inner side of the limiting groove, a detection plate is fixedly installed on the bottom of the cross plate, an adjustment groove is opened on the side wall of the detection plate, and a side baffle is horizontally slidably connected on the inner side of the adjustment groove, a No. 2 sliding groove is horizontally opened at the center of the top of the base, and the No. 2 sliding groove is located between the No. 1 sliding grooves on both sides and is perpendicular to the No. 1 sliding grooves.

[0008] In this technical solution, blades of various sizes can be fixed and clamped through the No. 2 slide groove, slider, fixing frame, torsion bolt and pressure plate. The distance between the two sliders is adjusted on the surface of the No. 2 slide groove to adapt to blades of different lengths. Then the blade body is placed on the surface of the slider under the pressure plate. Then the torsion bolt is manually turned to drive the pressure plate downward. The pressure plate will press and fix the blade on the surface of the slider, thereby maintaining stability and levelness, thereby improving the adaptability and detection accuracy of the device. Then the support frame is slidable through the No. 1 slide groove so that the detection plate under the cross plate can be aligned with the blade edge. The battery powers the electric pusher. After the rod is powered, it extends and drives the horizontal plate to move downward, so that the detection plate can fit the blade of the blade. By adjusting the slot, side baffles, lamp beads and camera, the state of the blade can be detected. The side baffles are slid to fit the blade from both sides, so that the blade body can be placed horizontally, so that it can remain stable and accurate when the detection plate is fitted. After the battery powers the lamp beads, it shines downward. The camera can observe the light band passing through the gap between the blade and the detection plate from the back. If the light band is uniform, it means that the blade body is relatively complete. If it is uneven, it means that the blade body is partially bent and tilted, which improves the detection accuracy and portability of the device.

[0009] As an optional solution of the technical solution of the present application, the bottom of the sliding block is slidably connected laterally on the inner side of the second sliding groove, and a fixing frame is fixedly installed on the top of the sliding block.

[0010] As an optional solution of the technical solution of the present application, the top end of the fixing frame is threadedly connected with a torsion bolt, the bottom of the torsion bolt passes through the fixing frame and is detachably connected to the pressure plate, and the blade body is movably placed on the top surface of the slider below the pressure plate.

[0011] As an optional solution of the technical solution of the present application, a battery is movably installed on the top of the horizontal plate on one side of the electric push rod, and a lamp bead is movably installed on the bottom of the horizontal plate vertically below the battery.

[0012] As an optional solution of the technical solution of the present application, the side wall of the side baffle is threadedly connected with an adjusting bolt, and the top end of the sliding block on one side of the fixing frame is threadedly connected with a fixing bolt.

[0013] As an optional solution of the technical solution of the present application, a pad is fixedly connected to the center of the top of the base on the side parallel to the No. 2 slide groove, and a camera is movably installed on the top of the pad.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can fix and clamp blades of various sizes through the No. 2 slide groove, slider, fixing frame, torsion bolt and pressure plate. The distance between the two sliders is adjusted on the surface of the No. 2 slide groove to adapt to blades of different lengths. Then the blade body is placed on the surface of the slider under the pressure plate. Then the torsion bolt is manually turned to drive the pressure plate downward. The pressure plate will press and fix the blade on the surface of the slider, thereby maintaining stability and levelness, thereby improving the adaptability and detection accuracy of the device.

[0016] 2. The present application can detect the state of the blade by adjusting the slot, side baffle, lamp beads and camera. The side baffle can be slid to fit the blade from both sides so that the blade body can be placed horizontally. This allows it to remain stable and accurate when the detection plate is fitted. The battery powers the lamp beads and then shines downward. The camera can observe the light band passing through the gap between the blade and the detection plate from the rear. If the light band is uniform, it means that the blade body is relatively complete. If it is uneven, it means that the blade body is partially bent and tilted, thereby improving the detection accuracy and portability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1 As shown, a blade horizontal detection mechanism includes a base 1, a support frame 3, a side baffle 8, a slider 12 and a blade body 16. A first slide groove 2 is vertically provided on both sides of the top of the base 1, and the bottoms of both sides of the support frame 3 are horizontally slidably connected on the inner side of the first slide groove 2.

[0025] like Figure 1 and Figure 2 As shown, an electric push rod 5 is fixedly installed below the center of the top of the support frame 3, and the bottom of the electric push rod 5 is fixedly connected to the center of the top of the cross plate 6. The left and right inner walls of the support frame 3 are provided with limiting grooves 301, and the two ends of the cross plate 6 are vertically slidably connected on the inner side of the limiting grooves 301. The limiting grooves 301 can make the cross plate 6 always remain horizontal during the lifting process.

[0026] like Figure 1 and Figure 2 As shown, a No. 2 slide groove 11 is horizontally opened in the center of the top of the base 1, and the No. 2 slide groove 11 is located between the No. 1 slide groove 2 on both sides and perpendicular to the No. 1 slide groove 2. The bottom of the slider 12 is horizontally slidably connected to the inner side of the No. 2 slide groove 11. A fixing frame 13 is fixedly installed on the top of the slider 12. The top of the fixing frame 13 is threadedly connected with a torsion bolt 14. The top of the slider 12 on one side of the fixing frame 13 is threadedly connected with a fixing bolt 121. The slider 12 can adapt to blades of different sizes by adjusting the spacing.

[0027] like Figure 2 As shown, the bottom of the torsion bolt 14 passes through the fixing frame 13 and is detachably connected to the pressure plate 15 , and the blade body 16 is movably placed on the top surface of the slider 12 below the pressure plate 15 , and the pressure plate 15 can fix the blade body 16 on the top surface of the slider 12 .

[0028] like Figure 3 As shown, a cushion block 17 is fixedly connected to the center of the top of the base 1 on the side parallel to the second slide slot 11, and a camera 18 is movably installed on the top of the cushion block 17. The camera 18 can observe the uniformity of the light band to determine the bending and tilt.

[0029] like Figure 4 As shown, a detection plate 7 is fixedly installed at the bottom of the horizontal plate 6, and an adjustment groove 701 is opened on the side wall of the detection plate 7. A side baffle plate 8 is laterally slidably connected to the inner side of the adjustment groove 701, and an adjustment bolt 801 is threadedly connected to the side wall of the side baffle plate 8. The side baffle plate 8 can make the blade body 16 placed horizontally.

[0030] like Figure 4 As shown, a battery 9 is movably mounted on the top of the horizontal plate 6 on one side of the electric push rod 5, and a lamp bead 10 is movably mounted on the bottom of the horizontal plate 6 vertically below the battery 9.

[0031] In actual use, blades of various sizes can be fixed and clamped through the No. 2 slide 11, the slider 12, the fixing frame 13, the twisting bolt 14 and the pressure plate 15. The distance between the two sliders 12 is adjusted on the surface of the No. 2 slide 11 to adapt to blades of different lengths. Then, the blade body 16 is placed on the surface of the slider 12 below the pressure plate 15. Then, the twisting bolt 14 is manually turned to drive the pressure plate 15 downward. The pressure plate 15 will press and fix the blade on the surface of the slider 12, thereby maintaining stability and levelness, thereby improving the adaptability and detection accuracy of the device. Then, the support frame 3 is slidable through the No. 1 slide 2 so that the detection plate 7 below the cross plate 6 can be aligned with the blade edge. The battery 94 After the electric push rod 5 is powered, it extends and drives the cross plate 6 to move downward, so that the detection plate 7 can fit the blade of the blade. The state of the blade can be detected by adjusting the slot 701, the side baffle 8, the lamp bead 10 and the camera 18. The side baffle 8 is slid to fit the blade from both sides, so that the blade body 16 can be placed horizontally, so that it can remain stable and accurate when the detection plate 7 is fitted. After the battery 9 powers the lamp bead 10, it irradiates downward, and the camera 18 can observe the light band passing through the gap between the blade and the detection plate 7 from the rear. If the light band is uniform, it means that the blade body 16 is relatively complete. If it is uneven, it means that the blade body 16 is partially bent and tilted, thereby improving the detection accuracy and portability of the device.
