DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0031] A particle material overturning detection device provided by the present invention will be described in detail below.

[0032] The present invention provides a particle material turnover detection device, comprising: an adjustable angle turnover mechanism 3, a vertical vibration plate 5 and a horizontal vibration plate 6; the adjustable angle turnover mechanism 3 is installed on the material transmission path to form an uneven loading platform, and the vertical vibration plate 5 and the horizontal vibration plate 6 are used to apply vertical vibration and horizontal vibration to the material on the turnover mechanism 3, respectively, to automatically flip and transport the material. The turnover mechanism 3 comprises a telescopic bottom plate 32 and a double-plane subunit 31, and a plurality of double-plane subunits 31 are connected end to end and installed on the upper surface of the telescopic bottom plate 32 to form an uneven loading platform.

[0033] Figure 1 It is an overall schematic diagram of a particle material overturning detection device of the present invention.

[0034] like Figure 1 As shown, the device as a whole includes: a feed port 1, a stage 2, a flip mechanism 3, a detection mechanism 4, a vertical vibration plate 5, a horizontal vibration plate 6, an industrial control computer 7, and a discharge port 8. The feed port 1 is the input end of the device as a whole, connected to the stage 2, and the size of the feed port 1 should be slightly smaller than the size of the stage 2; the flip mechanism 3 with adjustable angle is set on the table 21 of the stage 2, and the vertical vibration plate 5 and the horizontal vibration plate 6 are fixed on the bottom of the stage 2 in sequence; the detection mechanism 4 is set above the flip mechanism 3; the industrial control 7 is connected to the stage 2, the flip mechanism 3, the detection mechanism 4, the vertical vibration plate 5 and the horizontal vibration plate 6 by signal; the discharge port 8 is set at the output end of the device.

[0035] The material enters the turning mechanism 3 on the loading platform 2 from the feed port 1. Through the combined action of the vertical vibration plate 5 and the horizontal vibration plate 6, the material is vibrated and turned over and then transported. The material is monitored in real time by the detection mechanism 4 arranged above the turning mechanism 3.

[0036] Figure 2 This is a structural diagram of a feed port of a particle material overturn detection device of the present invention.

[0037] like Figure 2As shown, the feed port 1 includes: a feed channel 11, a pressure sensor 12, and an adjustable baffle 13. The feed channel 11 is a material transmission passage, which is used to continuously transmit materials to the turning mechanism 3 on the surface of the loading platform 2; the pressure sensors 12 are evenly distributed on the inner wall of the feed channel 11, and are used to monitor the material filling degree at the feed port 1 in real time to avoid excessive material accumulation and extrusion damage; the adjustable baffle 13 is located at the end of the feed port 1, and is used to fine-tune the discharge rate to avoid excessive material transmission to the turning mechanism 3 on the surface of the loading platform 2, causing material piling.

[0038] Figure 3 The present invention is a structural diagram of a loading platform of a particle material overturning detection device.

[0039] like Figure 3 As shown, the loading platform 2 is located at the end of the feed port 1 and receives a portion of the feed port 1. The loading platform 2 includes: a table top 21, a loading skirt 22, a bottom plate 23 and a support member 24. The bottom plate 23 is used to support the table top 21 and the loading skirt 22; the support member 24 is located between the bottom plate 23 and the table top 21, and its length is controlled by the industrial computer 7 to change the inclination angle of the table top 21 supported thereon. The table top 21 can be used alone to carry materials, and a turning mechanism 3 can also be installed thereon to achieve a better material turning effect. The loading skirt 22 is used to prevent materials from splashing outside the table top 21.

[0040] Figure 4a It is a schematic diagram of a turnover mechanism of a particle material turnover detection device of the present invention; Figure 4b It is a schematic diagram of the extension of the telescopic bottom plate of a granular material overturning detection device of the present invention.

[0041] like Figure 4a and 4b As shown, the flip mechanism 3 is located on the table 21 and connected to the table 21. The flip mechanism 3 includes a plurality of double-plane subunits 31 with adjustable angles and a telescopic bottom plate 32. The telescopic bottom plate 32 is a split bottom plate, and the total length of the telescopic bottom plate 32 is changed by telescoping to ensure that the minimum total length is greater than the length of the table 21.

[0042] The lengths of the two planes of the double-plane subunit 31 of the present invention and the cross-sectional shape of the two planes can be designed according to the size of the material, and an asymmetric design can also be adopted, that is, the lengths of the two small planes take different values.

[0043] The lengths of the two planes can also be different to form a non-isosceles triangle. In addition, the two planes can be designed into curved surfaces according to the characteristics of the material, such as arc surface, parabola, hyperbolic surface, free-form surface, etc.

[0044] In one embodiment of the present invention, the cross section of the dual-plane subunit 31 is an isosceles triangle.

[0045] Figure 5 It is a cross-sectional triangular structure diagram of a turnover mechanism subunit of a granular material turnover detection device of the present invention.

[0046] like Figure 5 As shown, the double-plane subunit 31 is a structure with a triangular cross-section, including: a first plane 311, a rotating shaft 312, a support column 313 and a second plane 314; the first plane 311 and the second plane 314 are hinged by the rotating shaft 312; the two ends of the support column 313 respectively abut the inner sides of the first plane 311 and the second plane 314, and the length of the support column 313 can be adjusted telescopically within a set range; the outermost double-plane subunits 31 are respectively connected to two split telescopic bottom plates 32, and the length of the telescopic bottom plates 32 is changed, thereby changing the base length of the triangle of each double-plane subunit 31, and finally adjusting the effective length of the flip mechanism 3.

[0047] When the lengths of the first plane 311 and the second plane 314 of the double-plane subunit 31 are constant, the change in the length of the base of the triangle of the double-plane subunit 31 can achieve the change in the top angle of the double-plane subunit 31. The support column 313 is located inside the double-plane subunit 31, and its two ends are respectively connected to the inner sides of the two small planes of the double-plane 311. The length of the support column 313 can be adjusted within a set range. When the shape of the triangle of each double-plane subunit 31 changes, a control instruction is issued through the industrial computer 7 to make all the support columns 313 extend to the same length to ensure the shape consistency of the triangle of each double-plane subunit 31.

[0048] The length of the first plane 311 and the second plane 314 ranges from 0.7 to 1.3 times the material size. If the length of the small plane is too small, the material will make point contact with the small plane, and high-efficiency flipping cannot be achieved; if the length of the small plane is too large, the material will accumulate in the "valley" between adjacent double-plane sub-units 31, forming a dead angle and affecting the output efficiency.

[0049] Figure 6 The present invention is a structural diagram of a detection mechanism of a particle material overturning detection device.

[0050] like Figure 6 As shown, the detection mechanism 4 is located directly above the flip mechanism 3, and is composed of a detection camera 41, a focusing mechanism 42, a position mechanism 43 and a mounting plate 44. The detection camera 41 is used to monitor the image information of the material on the flip mechanism 3 in real time. The focusing mechanism 42 is used to fine-tune the vertical position of the detection camera 41 to achieve precise focusing and clear imaging. The position mechanism 43 is used to fine-tune the position of the detection camera 41 to ensure that all materials can be imaged on the focal plane of the detection camera 41. The mounting plate 44 is used to fix the detection camera 41, the focusing mechanism 42 and the position mechanism 43, and the mounting plate 44 can be installed on the fixed frame according to actual conditions.

[0052] like Figure 7 As shown, the vertical vibration plate 5 is located below the bottom plate 23 of the stage 2, and is composed of a vertical vibration plate 51, a vertical vibrator 52 and a vertical controller 53. The vertical vibration plate 51 is used to connect with the bottom plate 23 of the stage 2, and transmit the vertical vibration generated by the vertical vibrator 52 to the stage 2 and the flip mechanism 3 thereon, and finally to the material, so that it vibrates in the vertical direction. Under the command control of the industrial computer 7, the vertical vibrator 52 generates vertical vibrations of different frequencies, amplitudes and waveforms, which produce a combined effect with the horizontal vibration of the horizontal vibration plate 6, so that the material is continuously flipped. The vertical controller 53 is connected to the industrial computer 7, and is used to receive instructions and control the vibration of the vertical vibrator 52.

[0053] Figure 8 This is a structural diagram of a horizontal vibration disk of a particle material overturning detection device of the present invention.

[0054] like Figure 8 As shown, the horizontal vibration plate 6 is located below the bottom plate 23 of the stage 2, and is composed of a horizontal vibration plate 61, a horizontal vibrator 62 and a horizontal controller 63. The horizontal vibration plate 61 is used to connect with the bottom plate 23 of the stage 2, and transmit the horizontal vibration generated by the horizontal vibrator 62 to the stage 2 and the adjustable angle flipping mechanism 3 thereon, and finally to the material, so that it vibrates in the horizontal direction. Under the command control of the industrial computer 7, the horizontal vibrator 62 generates horizontal vibrations of different frequencies, amplitudes and waveforms, which produce a combined effect with the vertical vibration of the vertical vibration plate 5, so that the material is continuously flipped. At the same time, its horizontal vibration is used to realize the continuous advancement of the material toward the discharge port 8. The horizontal controller 63 is connected to the industrial computer 7, and is used to receive instructions and control the vibration of the horizontal vibrator 62.

[0056] like Figure 9a and Figure 9b As shown, the discharge port 8 is located at the end of the loading platform 2, and is composed of a discharge bottom plate 81, a discharge skirt 82, a bagging interface 83 and a conveying interface 84. The discharge bottom plate 81 is used to receive the material output by the loading platform 2, and its width is larger than the loading platform 2 to prevent leakage. The discharge skirt 82 is located on both sides of the discharge bottom plate 81 to prevent material splashing. The bagging interface 83 and the conveying interface 84 are optional parts, which can be selected according to the needs of bagging or entering the next process, such as Figure 9a9a is the bagging interface 83 and 9b is the conveying interface 84.
