DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] <First embodiment>

[0036] Reference Figures 1 to 4 The conveying device 100 in the embodiment is arranged on a rack of a detection machine and is used for conveying detection articles, and comprises a reversing plate 10, a conveying assembly 20 and an electrical box 30.

[0037] The reversing plate 10 is detachably connected with the rack of the detection machine and has a first state of being fixedly connected with the rack and a second state of being disconnected with the rack.

[0038] Specifically, the reversing plate 10 is provided with a mounting screw hole, and the rack of the detection machine is provided with a mounting hole corresponding to the mounting screw hole. The reversing plate 10 is fixed by screwing the screw 11 through the mounting screw hole and the mounting hole, so that the reversing plate 10 is in the first state of being fixedly connected with the rack. In addition, by removing the screw 11, the reversing plate 10 can be in the second state of being disconnected with the rack.

[0039] In the embodiment, the mounting screw hole and the mounting hole are matched with the screw 11 to quickly fix or detach the reversing plate 10.

[0040] In some embodiments, the reversing plate 10 can also be detachably arranged in the rack by a clamping or other fixing mode.

[0041] The conveying assembly 20 is arranged on the upper side of the reversing plate 10 and is used for conveying articles located thereon.

[0042] Reference Figures 1-5The conveying assembly 20 comprises a driving wheel 21, a driven wheel 22, a belt 23 arranged between the driving wheel 21 and the driven wheel 22 in a tensioning manner, and a first support 24 and a second support 25 arranged on both sides of the driving wheel 21 and the driven wheel 22 in a facing manner.

[0043] One end of the first support 24 and the second support 25 is rotatably provided with a driving shaft of the driving wheel 21, and the other end is rotatably provided with a driven shaft of the driven wheel 22.

[0044] The first support 24 is further provided with a driving motor 26, and an output end of the driving motor 26 is in transmission connection with the driving shaft.

[0045] In the embodiment, the driving motor 26 is located below the driving wheel 21, the output shaft of the driving motor 26 is in transmission connection with the driving shaft of the driving wheel 21 through a belt, the driving motor 26 can drive the driving wheel 21 to rotate, thereby driving the belt 23 and the driven wheel 22 to move, and the articles are conveyed through the belt 23.

[0046] The first support 24 and the second support 25 are further provided with a connecting support 27 for connection, the connecting support 27 is located between the belt 23 and the reversing plate 10, the connecting support 27 is further connected with a weighing strain gauge 28, and the weighing strain gauge 28 is connected with the reversing plate 10.

[0047] Specifically, the weighing strain gauge 28 and the reversing plate 10 are correspondingly provided with screw holes, and the connecting screws are screwed from the lower side of the reversing plate 10 to connect and fix the weighing strain gauge 28. The weighing strain gauge 28 is connected and supported by the reversing plate 10, the connecting support 27 is connected and supported by the weighing strain gauge 28, the first support 24 and the second support 25 are connected and fixed by the connecting support 27, so that the conveying assembly 20 can be fixed on the reversing plate 10, and the weighing strain gauge 28 can detect the weight of the articles conveyed by the belt 23.

[0048] The one end of the belt 23 is further provided with a photoelectric sensor 29 and a reflective plate 210. The photoelectric sensor 29 and the reflective plate 210 are oppositely arranged on both sides of the belt 23. The first support 24 is provided with a first bearing frame 241 for bearing the photoelectric sensor 29. The second support 25 is provided with a second bearing frame 251 for bearing the reflective plate 210. In the embodiment, the photoelectric sensor 29 emits light and receives the light reflected by the reflective plate 210. During the process of conveying the detected object onto the belt 23 and then off the belt 23, there are two cases. In the first case, the object is located between the light emitting / reflection path of the photoelectric sensor 29 and the reflective plate 210, and blocks the transmission of the light. In the second case, the object is not located between the light emitting / reflection path of the photoelectric sensor 29 and the reflective plate 210, and the light can be normally transmitted. Based on the above logic, the positions of the photoelectric sensor 29 and the reflective plate 210 are set as follows: when the object is completely located on the belt 23 or off the belt 23, the photoelectric sensor 29 can receive the reflected light; otherwise, the photoelectric sensor 29 cannot receive the reflected light. Based on this, the reflective photoelectric sensor 29 and the reflective plate 210 can accurately determine whether the object is completely off the belt 23 or completely conveyed onto the belt 23 based on whether the photoelectric sensor 29 can receive the reflected light, thereby preventing inaccurate detection results caused by detecting the object when it is not completely placed or removed.

[0049] The electrical box 30 is fixed to the lower side of the reversing plate 10 and is used for arranging the electrical lines of the conveying assembly 20 therein. The electrical box 30 has an electrical line outlet 31 and a plurality of pipeline inlets.

[0050] Specifically, the electrical box 30 is provided with a plurality of pipeline inlets, and the number of the pipeline inlets is the same as the number of the electrical lines in the conveying assembly 20.

[0051] In the embodiment, the conveying assembly 20 has three electrical components, including the photoelectric sensor 29, the driving motor 26, and the weighing strain gauge 28.

[0052] Specifically, the electrical box 30 is provided with three pipeline inlets. The electrical box 30 is provided with a motor pipeline inlet 321 and a photoelectric pipeline inlet 322 on the side surface thereof facing the first support 24. The motor pipeline inlet 321 is located at one end close to the driving motor 26. The photoelectric pipeline inlet 322 is located at one end close to the photoelectric sensor 29. Meanwhile, the electrical box 30 is provided with a weighing pipeline inlet 323 on the side surface thereof facing the first support 24.

[0053] The electrical circuits of the drive motor 26, photoelectric sensor 29, and weighing strain gauge 28 can each enter the electrical box 30 through their respective conduit inlets (not shown in the specific electrical wiring diagram), ensuring a rational design of the wiring route. The separate conduit inlets allow each electrical circuit to enter the electrical box 30 without intersecting, effectively preventing wiring entanglement. Simultaneously, each electrical circuit enters its nearest conduit inlet, effectively preventing wiring detours and bends.

[0054] Meanwhile, when the reversing plate 10 is in the second state, it can rotate in a near-horizontal direction along an axis to change the direction of item transport. The electrical box 30 is also provided with an electrical line outlet 31 through which the power supply line passes to the outside of the conveying device 20. The electrical line outlet 31 is coaxially arranged with the reversing plate 10.

[0055] Specifically, the electrical wiring outlet 31 of the electrical box 30 is located on the side facing away from the commutator plate 10, and the electrical wiring outlet 31 and the center of the commutator plate 10 are located on the same axis of rotation. When the commutator plate 10 rotates to adjust the conveying direction, all electrical wiring in the conveying assembly 20 is output centrally through the electrical wiring outlet 31 and located on the same axis of rotation. During rotation, this effectively avoids the mixing and entanglement of various electrical wiring, thereby avoiding crossing and wear between wiring, and thus avoiding possible short circuits and circuit overload and damage.

[0056] In this embodiment, the conveying device 100 adjusts the conveying direction of the items by releasing the relative fixation between the reversing plate 10 and the testing machine, and rotating the reversing plate 10 around the rotation axis where the electrical circuit outlet 31 is located.

[0057] Specifically, the conveying device 100 is installed in the frame of the testing machine via a reversing plate 10. When the conveying direction needs to be adjusted, the relative fixation between the reversing plate 10 and the testing machine is released, and the reversing plate 10 is rotated around the rotation axis where the electrical circuit outlet 31 is located. This drives the conveying assembly 20 to rotate accordingly, flexibly adjusting the belt conveying direction. Simultaneously, during the reversing process, mounting screw holes and mounting holes are provided on the reversing plate 10 and the frame, allowing for quick fixing or disassembly of the reversing plate 10 by screws 11. Furthermore, the electrical circuits of the conveying assembly 20 are centrally connected to the outside through the electrical circuit outlet 31 located on the rotation axis, ensuring that all electrical circuits connected to the outside remain on the rotation axis during rotation. This effectively avoids entanglement and significant changes in the position of each electrical circuit during the reversing rotation.

[0058] <Second Implementation Method>

[0059] refer to Figure 6 andFigure 7 This embodiment provides a weight detection machine, which includes a conveying device 100. The weight detection machine also includes a frame 200 and an electrical box 300. The frame 200 has mounting holes, which correspond to the mounting screw holes at both ends of the reversing plate 10. The reversing plate 10 is fixed by screws 11 passing through the mounting screw holes and mounting holes, and the conveying device 100 is installed in the frame 200.

[0060] The electrical control box 300 is equipped with a pipeline connector 301. The electrical lines of the drive motor 26, photoelectric sensor 29 and weighing strain gauge 28 in the conveying component 20 are respectively connected to the electrical box 30, and are concentrated from the electrical line outlet 31 and connected to the electrical control box 300 through the pipeline connector 301, thereby controlling the conveying component 20 accordingly.

[0061] In this embodiment, the pipeline connector 301 is located below the electrical line outlet 31 in the horizontal direction. After the electrical line of the conveying component 20 is output from the electrical line outlet 31, it can be connected downward to the pipeline connector 301, which further ensures the reasonable layout of the electrical line and reduces the detours and bends of the electrical line.

[0062] The weight detection machine of this embodiment can sense whether the material has been completely conveyed onto the belt 23 or detached from the belt 23 by photoelectric sensor 29, and perform weight detection on the material conveyed by the belt 23 by weighing strain gauge 28.

[0063] When the weight inspection machine needs to adjust the conveying direction, the reversing plate 10 can be disassembled, rotated accordingly, and then fixed to complete the conveying direction adjustment. (Reference) Figures 8-11 When the weight detection machine equipped with the conveying device 100 in this embodiment needs to change the conveying direction, the rotation reversal process is as follows:

[0064] refer to Figure 8 First, remove screw 11, then lift the reversing plate 10. The conveyor assembly 20 and electrical box 30 installed on both sides of the reversing plate 10 will be lifted together; see reference. Figure 9 and Figure 10 Then, the conveying device 100 is rotated 180° as a whole, and during the rotation, the outlet pipe 31 remains located on the axis of rotation, effectively avoiding line entanglement; Reference Figure 11 After rotation, align the mounting screw holes at both ends of the reversing plate 10 with the mounting holes on the frame 10, lower the reversing plate 10 onto the frame 200, tighten the screws 11 to fix the reversing plate 10, and complete the 180° adjustment of the conveying direction.

[0065] In some embodiments, the conveying device 100 can also be rotated by 90 degrees or other angles to adjust the corresponding conveying direction according to the actual scene requirements, and only corresponding mounting screw holes and mounting holes are needed to be opened in the corresponding positions of the rack of the weight detection machine and the reversing plate 10, and the screw is matched with the rack to fix or disassemble the reversing plate 10.

[0066] In some embodiments, the conveying device 100 can also be arranged in the rack of a visual detection machine or other types of detection machines that need to be conveyed by a belt through a detachable mounting mode, and the reversing plate 10 can quickly disassemble, rotate and fix the conveying device 100, so as to flexibly adjust the belt conveying direction.

[0067] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
