[0037] Figure 5 Most of the devices in the above structure are shown in

[0038] The control module 6 includes a wireless network communication module, an MCU and supporting circuits. The MCU is connected to all the motors in the present utility model. The MCU receives external wireless network signals and controls the start and stop of the motors according to instructions. This implementation is prior art and not an innovation point of the present utility model, so it will not be elaborated here.

[0039] See Figure 2 , the base 1 is composed of a rectangular frame and a triangular frame connected as a whole. The columns 2 are fixed on the rectangular frame. The base 1 is provided with three anchor bolts 1-1, which are respectively located at the vertices of the triangle and the two vertices of the rectangle far from the triangle. The anchor bolts 1-1 are used to adjust the overall level of the target machine.

[0040] The positioning holes 3-1 and mounting holes 3-2 are provided on the mounting rod 3. The mounting rod 3 is positioned at the top of the column 2 by inserting the positioning pin 3-3 into the positioning hole 3-1. There are two positioning holes 3-1, which are respectively located near the top and bottom of the mounting rod 3 and are used to raise and lower the target paper frame 4.

[0041] The paper frame 4 is on the mounting rod 3 through the mounting hole 3-2: Refer to Figure 3 、 4 、5. The mounting plate 4-1 is arranged in the middle part inside the frame. The mounting bolt 3-4 passes through the hole on the mounting plate 4-1 and the mounting hole 3-2 to set the target paper frame 4 on the mounting rod 3.

[0042] The target paper frame 4 is of a rectangular frame structure. A lining plate support 4-2 composed of 4 support rods is arranged in the middle of the target paper frame 4. A lining plate 4-3 is arranged in the center of the lining plate support 4-2 for supporting the target paper. An upper target paper guide shaft 4-4 and a lower target paper guide shaft 4-5 are respectively arranged near the top and bottom of the lining plate support 4-2. The control module 6 is arranged on the side frame of the target paper frame 4.

[0043] At the four corners of the target paper frame 4, that is, at the upper right-angle position and the lower right-angle position, 2 upper mounting frames 4-6 and 2 lower mounting frames 4-7 are respectively arranged. The target paper supply device and the target paper recycling device are respectively arranged at the top and bottom of the target paper frame 4 by means of the upper mounting frame 4-6 and the lower mounting frame 4-7.

[0044] The target paper used for the assessment of the Type 97 anti-riot gun for official use is not a single-sheet structure, but a target paper roll wound on the upper target paper roller 4-12. In order to facilitate the disassembly and assembly of the upper target paper roller 4-12, the target paper supply device proposed by the present utility model includes 2 upper tapered head assemblies 4-8 arranged at the top of the target paper frame 4 by means of the upper mounting frame 4-6 and the upper target paper roller 4-12 installed between the two upper tapered head assemblies 4-8.

[0045] Refer to Figure 3 、 4 、11. The upper tapered head assembly 4-8 includes an upper tapered head rotating shaft 4-8-1 and an upper tapered head 4-8-2 arranged at one end of the upper tapered head rotating shaft 4-8-1. The other end of the upper tapered head rotating shaft 4-8-1 is limited by the upper tapered head rotating shaft mounting bearing I4-8-3 and the upper tapered head rotating shaft mounting bearing II4-8-4 inside the upper mounting frame 4-6. The upper tapered head fastening screw hole 4-8-11 is arranged on the upper tapered head 4-8-2.

[0046] In this embodiment, in the structure of one upper tapered head assembly 4-8, the upper tapered head 4-8-2 is directly connected to the upper tapered head rotating shaft 4-8-1. In the structure of the other upper tapered head assembly 4-8, refer to Figure 11, the upper conical head connector 4-8-5 is connected to one end of the upper conical head rotating shaft 4-8-1 through the upper conical head fastening bolt 4-8-7, and the upper conical head 4-8-2 is threadedly connected to the upper conical head connector 4-8-5.

[0047] The upper target paper roller 4-12 is of a hollow structure, and the diameter of its internal hollow part is larger than the diameter of the end of the upper conical head 4-8-2 and smaller than the diameter of the top of the inclined surface of the upper conical head 4-8-2.

[0048] Loosen the upper conical head fastening bolt 4-8-7, and the upper conical head connector 4-8-5 and the upper conical head 4-8-2 move horizontally to the left along the upper conical head rotating shaft 4-8-1 to make way. Insert the upper target paper roller 4-12 into one upper conical head 4-8-2, then the upper conical head connector 4-8-5 and the upper conical head 4-8-2 move horizontally to the right along the upper conical head rotating shaft 4-8-1, and the two upper conical heads 4-8-2 clamp the upper target paper roller 4-12, and tighten the upper conical head fastening bolt 4-8-7. Rotate the upper conical head 4-8-2 to move along the upper conical head connection thread 4-8-6 to further tighten the upper target paper roller 4-12, and then screw the bolt into the upper conical head fastening screw hole 4-8-11 to complete the assembly of the upper target paper roller 4-12.

[0049] During operation, the target paper recycling device drives the target paper to move downward, the target paper drives the upper target paper roller 4-12 to rotate, and the upper target paper roller 4-12 drives the upper conical head 4-8-2 to rotate.

[0050] In order to lay the proof target paper 5 flat on the lining plate 4-3, see Figure 11 、 15 , a damping belt 4-8-8 is arranged on the upper conical head rotating shaft 4-8-1 between the upper conical head rotating shaft mounting bearing I 4-8-3 and the upper conical head rotating shaft mounting bearing II 4-8-4. One end of the damping belt 4-8-8 is fixed, and the other end is connected to the damping belt tensioning bolt 4-8-10 through the damping belt tensioning spring 4-8-9.

[0051] Tighten the damping belt tensioning spring 4-8-9 through the tensioning bolt 4-8-10, and the damping belt 4-8-8 generates frictional force with the upper conical head rotating shaft 4-8-1. When the target paper recycling device stops working, the upper conical head rotating shaft 4-8-1 stops rotating synchronously to ensure that the target paper 5 is laid flat on the lining plate 4-3.

[0052] See Figure 3 、 4, 12, 13, 14, the target paper recycling device includes two lower conical head components 4-9 arranged at the bottom of the target paper frame 4 by means of the lower mounting frame 4-7, a target paper recycling roller 4-13 installed between the two lower conical head components 4-9, a embossing roller 4-10 arranged by means of an embossing roller shaft mounting bearing 4-10-2 in the lower mounting frame 4-7, and a rubber roller 4-11 close to the embossing roller 4-10.

[0053] The lower conical head component 4-9 includes a lower conical head rotating shaft 4-9-1 and a lower conical head 4-9-2 arranged at one end of the lower conical head rotating shaft 4-9-1. The other end of the lower conical head rotating shaft 4-9-1 is limited by a lower conical head rotating shaft mounting bearing I 4-9-3 and a lower conical head rotating shaft mounting bearing II 4-9-4 inside the lower mounting frame 4-7. A lower conical head fastening screw hole 4-9-11 is arranged on the lower conical head 4-9-2;

[0054] In this embodiment, in the structure of one lower conical head component 4-9, the lower conical head 4-9-2 is directly connected to the lower conical head rotating shaft 4-9-1. In the structure of the other lower conical head component 4-9, see Figure 12 , the lower conical head connector 4-9-5 is connected to one end of the lower conical head rotating shaft 4-9-1 by a lower conical head fastening bolt 4-9-7, and the lower conical head 4-9-2 is threadedly connected to the lower conical head connector 4-9-5.

[0055] Similarly, the target paper recycling roller 4-13 is also of a hollow structure, and the diameter of the internal hollow part thereof is larger than the diameter of the end of the lower conical head 4-9-2 and smaller than the diameter of the top of the inclined surface of the lower conical head 4-9-2.

[0056] Loosen the lower conical head fastening bolt 4-8-7, and the lower conical head connector 4-9-5 and the lower conical head 4-9-2 move horizontally to the left along the lower conical head rotating shaft 4-9-1 to make way. Insert the target paper recycling roller 4-13 into one lower conical head 4-9-2, and then the lower conical head connector 4-9-5 and the lower conical head 4-9-2 move horizontally to the right along the lower conical head rotating shaft 4-9-1. The two lower conical heads 4-9-2 clamp the target paper recycling roller 4-13, and tighten the lower conical head fastening bolt 4-9-7. Rotate the lower conical head 4-9-2 to move along the lower conical head connection thread 4-9-6 to further tighten the target paper recycling roller 4-13, and then screw the bolt into the lower conical head fastening screw hole 4-9-11 to complete the assembly of the target paper recycling roller 4-13.

[0057] In this embodiment, the lower conical head rotating shaft 4-9-1 and the embossing roller 4-10 are equipped with motors and are driving shafts, and the upper conical head rotating shaft 4-8-1 and the rubber roller 4-11 are driven shafts.

[0058] See Figure 12 , 14, a target paper recycling motor 4-14 is arranged on the side of the lower installation frame 4-7, a gear is arranged on the target paper recycling motor shaft 4-14-1, a gear is arranged on the lower conical head rotating shaft 4-9-1, and the target paper recycling motor shaft 4-14-1 is connected with the lower conical head rotating shaft 4-9-1 through a recycling chain 4-14-2;

[0059] See Figure 13 , a target paper driving motor 4-15 is arranged on the side of another lower installation frame 4-7, a gear is arranged on the target paper driving motor shaft 4-15-1, a gear is arranged on the embossing roller shaft 4-10-1 of the embossing roller 4-10, and the target paper driving motor shaft 4-15-1 is connected with the embossing roller shaft 4-10-1 through a driving chain 4-15-2.

[0060] The target paper 5 passes through the gap between the embossing roller 4-10 and the rubber roller 4-11. The embossing roller 4-10 and the rubber roller 4-11 clamp the target paper 5. When the embossing roller 4-10 rotates, it drives the rubber roller 4-11 to rotate, and the target paper 5 moves accordingly, realizing automatic paper feeding.

[0061] In order to avoid loose cooperation between the embossing roller 4-10 and the rubber roller 4-11, in this embodiment, see Figure 3 、 12 、14, the rubber roller 4-11 is connected with a rubber roller mounting bearing 4-11-1, and a rubber roller pressing spring 4-11-3 connected with a rubber roller pressing bolt 4-11-2 limits the rubber roller mounting bearing 4-11-1 in the U-shaped groove of the mounting frame 4-7.

[0062] In order to facilitate the installation of the target paper, in this embodiment, see Figure 13 、 14 , a pry bar 4-16 is arranged near the rubber roller 4-11. One end of the pry bar 4-16 is axially connected with the surface of the lower installation frame 4-7 through a bolt 4-16-1, and a handle 4-16-2 is installed at the other end. A positioning bolt 4-16-3 is arranged at one end of the pry bar 4-16 near the handle 4-16-2, and a plurality of pry bar positioning holes 4-16-4 are arranged on the lower installation frame 4-7 at the position corresponding to the positioning bolt 4-16-3.

[0063] When installing the target paper, force the pry bar 4-16 towards the rubber roller 4-11 and place the positioning bolt 4-16-3 in the corresponding pry bar positioning hole 4-16-4. Due to the rubber roller pressing spring 4-11-3, the rubber roller 4-11 moves away from the embossing roller 4-10, and a gap appears between the two. Pass the target paper through the gap, then move the pry bar 4-16 away from the rubber roller 4-11, and the embossing roller 4-10 and the rubber roller 4-11 are pressed tightly.

[0064] The pressing bolt 4-11-2 of the rubber roller can adjust the pressing degree of the embossing roller 4-10 and the rubber roller 4-11 through the rubber roller pressing spring 4-11-3.

[0065] As the target paper is wound around the target paper recovery roller 4-13, its outer diameter will change, while the diameter of the embossing roller 4-10 remains unchanged. Therefore, in this embodiment, according to the diameter of the embossing roller 4-10 and the size of the target paper used each time, the rotation speed of the target paper driving motor 4-15 is controlled to complete the automatic paper feeding and replacement of the target paper.

[0066] To ensure that the used target paper does not accumulate between the rubber roller 4-11 and the target paper recovery roller 4-13, it is necessary to ensure that the surface linear velocity of the target paper recovery roller 4-13 is greater than that of the embossing roller 4-10. In this embodiment, the diameter of the target paper recovery roller 4-13 is greater than that of the embossing roller 4-10, and the target paper recovery motor 4-14 and the target paper driving motor 4-15 are started and stopped simultaneously and have the same rotation speed.

[0067] The torque of the target paper recovery motor 4-14 is much smaller than the tearing strength of the target paper 5. When the target paper 5 is tightened, the target paper recovery motor 4-14 generates "lost rotation". In this way, it can not only ensure that the target paper 5 does not accumulate, but also avoid the breakage of the target paper 5.

[0068] To ensure the stability of the target machine during use, in this embodiment, refer to Figure 13 , through holes are provided on the lower mounting frame 4-7, and anti-rotation pins 4-17 are provided on the through holes. A return spring 4-17-1 is provided on the part of the anti-rotation pin 4-17 located inside the lower mounting frame 4-7, and anti-rotation holes are provided on the column 2 corresponding to the positions of the anti-rotation pins 4-17.

[0069] The target machine without the target paper installed is as Figure 5 shown.

[0070] Before using the target machine, first rotate the target paper frame 4 along the mounting bolt 3-4. As Figure 10 shown, the upper mounting frame 4-6 and the lower mounting frame 4-7 face upward, and the bracket 1-2 is inserted into the lower mounting frame support hole 4-7-1 for fixation.

[0071] Wind the target paper 5 around the upper target paper roller 4-12, loosen the upper tapered head fastening bolt 4-8-7, and the upper tapered head connector 4-8-5 and the upper tapered head 4-8-2 move horizontally to the left along the upper tapered head rotation axis 4-8-1 to make way. Insert the upper target paper roller 4-12 into an upper tapered head 4-8-2, then the upper tapered head connector 4-8-5 and the upper tapered head 4-8-2 move horizontally to the right along the upper tapered head rotation axis 4-8-1, and the two upper tapered heads 4-8-2 clamp the upper target paper roller 4-12. Tighten the upper tapered head fastening bolt 4-8-7. Rotate the upper tapered head 4-8-2 to move along the upper tapered head connection thread 4-8-6 to further clamp the upper target paper roller 4-12, and then screw the bolt into the upper tapered head fastening screw hole 4-8-11 to complete the assembly of the upper target paper roller 4-12.

[0072] Loosen the lower tapered head fastening bolt 4-8-7, and the lower tapered head connector 4-9-5 and the lower tapered head 4-9-2 move horizontally to the left along the lower tapered head rotation axis 4-9-1 to make way. Insert the target paper recovery roller 4-13 into a lower tapered head 4-9-2, then the lower tapered head connector 4-9-5 and the lower tapered head 4-9-2 move horizontally to the right along the lower tapered head rotation axis 4-9-1, and the two lower tapered heads 4-9-2 clamp the target paper recovery roller 4-13. Tighten the lower tapered head fastening bolt 4-9-7. Rotate the lower tapered head 4-9-2 to move along the lower tapered head connection thread 4-9-6 to further clamp the target paper recovery roller 4-13, and then screw the bolt into the lower tapered head fastening screw hole 4-9-11 to complete the assembly of the target paper recovery roller 4-13.

[0073] The target paper 5 covers the lining plate 4-3 along the upper target paper guide shaft 4-4. Pry open the rubber roller 4-11, wind one end of the target paper 5 around the target paper recovery roller 4-13, and tighten the target paper 5. The direction of the target paper 5 is as Figure 16 shown.

[0074] Pull out the anti-rotation pin 4-17, rotate the target paper frame 4, and insert the anti-rotation pin 4-17 into the anti-rotation hole. At this time, the state of the target machine is as Figure 6 shown.

[0075] To avoid damaging the equipment during shooting, in this embodiment, use the shield 7 as shown in Figure 7 and install the shield 7 on the target machine to cover the lining plate 4-3, as shown in Figure 8 shown.

[0076] After the assembly of the target machine is completed, if it needs to be transported, each part can be disassembled. In this embodiment, rotate the target paper frame 4 along the mounting bolt 3-4, as shown in Figure 9 shown, with the upper mounting frame 4-6 and the lower mounting frame 4-7 facing downwards. The bracket 1-2 is inserted into the upper mounting frame support hole 4-6-1 for fixation, and at the same time, the buckle 4-6-2 clamps the bracket 1-2. In this state, the target machine is convenient for transportation.

[0077] See Figure 17 Figure 17 , the structure of the buckle 4-6-2 includes a bottom plate 4-6-2-1, a rotating shaft 4-6-2-2 arranged at the middle position of the bottom plate 4-6-2-1, two holding rods 4-6-2-3 symmetrically installed on the rotating shaft 4-6-2-2, and a return spring 4-6-2-4 connecting the bottom plate 4-6-2-1 and the holding rods 4-6-2-3; the two holding rods 4-6-2-3 enclose an arc shape, with an opening therebetween, and the size of the opening is smaller than the diameter of the bracket 1-2.

[0078] The bracket 1-2 presses the holding rods 4-6-2-3, the holding rods 4-6-2-3 press the return spring 4-6-2-4, the opening expands, the bracket 1-2 enters the arc shape, and under the action of the return spring 4-6-2-4, the holding rods 4-6-2-3 reset, realizing the fixation of the bracket 1-2.

[0079] The process of pulling out the bracket 1-2 is similar to the above and will not be elaborated here.

[0080] The on-site supervision computer is a laptop computer, which is connected to a face recognition device and a second-generation ID card reading module.

[0081] For the convenience of on-site layout, the automatic target reporting terminal is of a portable chassis structure. The portable chassis houses the camera and the tablet computer. The automatic target reporting terminal further includes a face recognition device, a second-generation ID card reading module, and a voice power amplifier connected to the tablet computer; the camera is a zoom high-definition camera, which is built into the base bin of the portable terminal box. An opening is made at the rear side of the base bin of the portable terminal box, and the zoom high-definition camera lens takes external images through the opening. The zoom high-definition camera is equipped with an electric control pan-tilt head.

[0082] Before the target shooting assessment, first arrange the shooting range: install an automatic paper feeding target machine and place it at the target position. Place an automatic target reporting terminal at each target position, place a scene camera at an appropriate position to ensure that the scene camera can obtain images of all target positions, place a central wireless router and an on-site supervision computer, and connect all on-site devices.

[0083] During the target shooting assessment, the tester first verifies his / her identity through the face recognition device and the second-generation ID card reading module in front of the on-site supervision computer and then enters the target position; after entering the target position, the tester's identity is secondarily authenticated through the face recognition device and the second-generation ID card reading module in the automatic target reporting terminal, and the result is uploaded to the on-site supervision computer. After the on-site supervision computer confirms that it is correct, the supervisor sends an instruction to the automatic target reporting terminal through the on-site supervision computer and the wireless network. The automatic paper feeding target machine automatically feeds the target paper according to the instruction. The automatic target reporting terminal focuses the zoom high-definition camera lens on the target paper of the corresponding target position and broadcasts the instruction through the voice power amplifier to start the assessment.

[0084] During the assessment process, the zoom high-definition camera lens captures the target paper image and uploads it to the on-site supervision computer to achieve automatic target reporting.

[0085] A bullet hole recognition module can also be set in the automatic target reporting terminal. After the shooting, the recognition results are uploaded to the on-site supervision computer to achieve a more intuitive automatic target reporting.

[0086] Mature technologies can be used for bullet hole recognition, such as the "Intelligent Target Reporting System and Method Based on Multi-Bullet Hole Pattern Recognition Algorithm" proposed in Chinese Patent CN106802113B and the "Bullet Hole Recognition Method Based on Deep Learning" proposed in CN108805210B. The above methods can be used in the bullet hole recognition module of this system.
