Detailed implementation mode

[0031] In order to more clearly illustrate the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] A wireless network remote control automatic paper feeding target machine, comprising a base 1, two columns 2 fixed on the base 1, a mounting rod 3 sleeved in the columns 2, a target paper frame 4 arranged on the mounting rod 3, and a control module 6. A target paper supply device is arranged at the top of the target paper frame 4, and a target paper recycling device is arranged at the bottom of the target paper frame 4.

[0033] Figure 5 Most of the devices in the above structure are shown in the figure. Since the control module 6 is arranged on the other side of the target paper frame 4, it is not shown in the figure.

[0034] The control module 6 includes a wireless network communication module, an MCU and supporting circuits. The MCU is connected to all 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 the innovation point of the present utility model, so it will not be elaborated here.

[0035] See Figure 1 、 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.

[0036] Positioning holes 3-1 and mounting holes 3-2 are arranged on the mounting rod 3. The mounting rod 3 is positioned at the top of the column 2 by inserting a 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 for raising and lowering the target paper frame 4.

[0037] The paper frame 4 is arranged on the mounting rod 3 through the mounting hole 3-2: See Figure 3 、 4 、5. The mounting plate 4-1 is arranged at the middle part inside the side frame. The mounting bolt 3-4 passes through the hole on the mounting plate 4-1 and the mounting hole 3-2 to arrange the target paper frame 4 on the mounting rod 3.

[0038] The target paper frame 4 is of a rectangular frame structure. A lining plate support 4-2 composed of four support rods is arranged in the middle of the target paper frame 4. A lining plate 4-3 is arranged at 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.

[0039] At the four corners of the target paper frame 4, that is, at the upper right-angle position and the lower right-angle position, two upper mounting frames 4-6 and two 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.

[0040] 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 roll of target paper wound around 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 two upper tapered head assemblies 4-8 provided on 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.

[0041] See Figure 3 、 4 、11, the upper tapered head assembly 4-8 includes an upper tapered head rotating shaft 4-8-1, an upper tapered head 4-8-2 provided 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 I 4-8-3 and the upper tapered head rotating shaft mounting bearing II 4-8-4 inside the upper mounting frame 4-6. The upper tapered head fastening screw hole 4-8-11 is provided on the upper tapered head 4-8-2.

[0042] 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, see Figure 11 , the upper tapered head connector 4-8-5 is connected to one end of the upper tapered head rotating shaft 4-8-1 through the upper tapered head fastening bolt 4-8-7, and the upper tapered head 4-8-2 is threadedly connected to the upper tapered head connector 4-8-5.

[0043] The upper target paper roller 4-12 is of a hollow structure, and the diameter of the internal hollow part is larger than the diameter of the end of the upper tapered head 4-8-2 and smaller than the diameter of the top of the inclined surface of the upper tapered head 4-8-2.

[0044] Loosen the upper tapered head fastening bolt 4-8-7, 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 rotating shaft 4-8-1 to make way. Insert the upper target paper roller 4-12 into one 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 rotating shaft 4-8-1, and the two upper tapered heads 4-8-2 clamp the upper target paper roller 4-12, and 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 tighten 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.

[0045] During operation, the target paper recovery 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 tapered head 4-8-2 to rotate.

[0046] In order to lay the target paper 5 flat on the backing plate 4-3, refer to Figure 11 、 15 , a damping belt 4-8-8 is provided on the upper conical head rotating shaft 4-8-1 between the bearing I 4-8-3 for the upper conical head rotating shaft and the bearing II 4-8-4 for the upper conical head rotating shaft. 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.

[0047] By tightening the damping belt tensioning spring 4-8-9 with the tensioning bolt 4-8-10, 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, ensuring that the target paper 5 is laid flat on the backing plate 4-3.

[0048] Refer to Figure 3 、 4 、12、13、14, the target paper recycling device includes two lower conical head assemblies 4-9 provided 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 assemblies 4-9, a embossing roller 4-10 provided by means of the 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.

[0049] The lower conical head assembly 4-9 includes a lower conical head rotating shaft 4-9-1 and a lower conical head 4-9-2 provided 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 the bearing I 4-9-3 for the lower conical head rotating shaft and the bearing II 4-9-4 inside the lower mounting frame 4-7. Lower conical head fastening screw holes 4-9-11 are provided on the lower conical head 4-9-2;

[0050] In this embodiment, in the structure of one lower conical head assembly 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 assembly 4-9, refer to 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 through the 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.

[0051] Similarly, the target paper recycling roller 4-13 is also of a hollow structure, and the diameter of the internal hollow part 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.

[0052] Loosen the lower tapered head fastening bolt 4-8-7. 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 one of the lower tapered heads 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 tighten the target paper recovery roller 4-13. 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.

[0053] In this embodiment, the lower tapered head rotation axis 4-9-1 and the embossing roller 4-10 are equipped with a matching motor and are the driving shafts, while the upper tapered head rotation axis 4-8-1 and the rubber roller 4-11 are the driven shafts.

[0054] See Figure 12 、 14 , a target paper recovery motor 4-14 is provided on the side of the lower mounting frame 4-7. A gear is provided on the target paper recovery motor shaft 4-14-1, and a gear is provided on the lower tapered head rotation axis 4-9-1. The target paper recovery motor shaft 4-14-1 and the lower tapered head rotation axis 4-9-1 are connected by a recovery chain 4-14-2;

[0055] See Figure 13 , a target paper driving motor 4-15 is provided on the side of another lower mounting frame 4-7. A gear is provided on the target paper driving motor shaft 4-15-1, and a gear is provided on the embossing roller shaft 4-10-1 of the embossing roller 4-10. The target paper driving motor shaft 4-15-1 and the embossing roller shaft 4-10-1 are connected by a driving chain 4-15-2.

[0056] 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 to achieve automatic paper feeding.

[0057] 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 to the rubber roller mounting bearing 4-11-1. The rubber roller pressing spring 4-11-3 connected to the rubber roller pressing bolt 4-11-2 limits the rubber roller mounting bearing 4-11-1 in the U-shaped groove of the lower mounting frame 4-7.

[0058] To facilitate the installation of the target paper, in this embodiment, see Figure 13 、14 A crowbar 4-16 is provided near the rubber roller 4-11. One end of the crowbar 4-16 is axially connected to the surface of the lower mounting 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 provided at one end of the crowbar 4-16 near the handle 4-16-2, and a plurality of crowbar positioning holes 4-16-4 are provided on the lower mounting frame 4-7 at positions corresponding to the positioning bolt 4-16-3.

[0059] When installing the target paper, force the crowbar 4-16 towards the rubber roller 4-11 and place the positioning bolt 4-16-3 in the corresponding crowbar positioning hole 4-16-4. Due to the rubber roller compression spring 4-11-3, the rubber roller 4-11 moves away from the embossing roller 4-10, creating a gap between them. Pass the target paper through the gap, then move the crowbar 4-16 away from the rubber roller 4-11, and the embossing roller 4-10 and the rubber roller 4-11 are pressed tightly together.

[0060] The rubber roller compression bolt 4-11-2 can adjust the compression degree between the embossing roller 4-10 and the rubber roller 4-11 through the rubber roller compression spring 4-11-3.

[0061] As the target paper is wound around the target paper recovery roller 4-13, its outer diameter changes, 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 drive motor 4-15 is controlled to complete the automatic paper feeding and replacement of the target paper.

[0062] 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 speed of the target paper recovery roller 4-13 is greater than the surface linear speed of the embossing roller 4-10. In this embodiment, the diameter of the target paper recovery roller 4-13 is greater than the diameter of the embossing roller 4-10, and the target paper recovery motor 4-14 and the target paper drive motor 4-15 are started and stopped simultaneously and have the same rotation speed.

[0063] 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 experiences "slip", which can ensure that the target paper 5 does not accumulate and also avoid the breakage of the target paper 5.

[0064] To ensure the stability of the target machine during use, in this embodiment, refer to Figure 13 A through hole is provided on the lower mounting frame 4-7, and a rotation stop pin 4-17 is provided on the through hole. A return spring 4-17-1 is provided on the part of the rotation stop pin 4-17 located inside the lower mounting frame 4-7, and a rotation stop hole is provided on the column 2 at a position corresponding to the rotation stop pin 4-17.

[0065] The target machine without the target paper installed is as Figure 5 shown.

[0066] Before using the target drone, 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 support hole 4-7-1 of the lower mounting frame for fixation.

[0067] Wind the target paper 5 around the upper target paper roller 4-12. Loosen the upper tapered head fastening bolt 4-8-7. 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 rotating shaft 4-8-1 to make way. Insert the upper target paper roller 4-12 into one of the upper tapered heads 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 rotating shaft 4-8-1. The two upper tapered heads 4-8-2 clamp the upper target paper roller 4-12, and 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 tighten the upper target paper roller 4-12. 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.

[0068] Loosen the lower tapered head fastening bolt 4-8-7. 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 rotating shaft 4-9-1 to make way. Insert the target paper recovery roller 4-13 into one of the lower tapered heads 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 rotating shaft 4-9-1. The two lower tapered heads 4-9-2 clamp the target paper recovery roller 4-13, and 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 tighten the target paper recovery roller 4-13. 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.

[0069] The target paper 5 passes through the upper target paper guide shaft 4-4 to cover the lining plate 4-3. 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.

[0070] 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. The state of the target drone at this time is as Figure 6 shown.

[0071] To avoid damaging the equipment during shooting, in this embodiment, use a shield 7 as Figure 7 shown, and install the shield 7 on the target drone to block the lining plate 4-3, as Figure 8 shown.

[0072] After the target drone is assembled, if it needs to be transported, each part can be disassembled. In this embodiment, the target paper frame 4 is rotated along the mounting bolt 3-4. As Figure 9 shown, the upper mounting frame 4-6 and the lower mounting frame 4-7 face downward, and the support 1-2 is inserted into the support hole 4-6-1 of the upper mounting frame for fixation, and at the same time, the buckle 4-6-2 holds the support 1-2 tightly.
