Referring to fig. 1 and 2, the box 1 is commonly referred to as a "black box". In this embodiment, the case 1 is a square case. Referring to fig. 2, the box body 1 includes a front plate 11, a front plate opening 11a is opened on the front plate 11, and a target limiting plate 4 is disposed on the front plate opening 11 a. Specifically, referring to fig. 2, the front plate 11 is provided with a positioning pin 11b, and the target position limiting plate 4 is provided with a positioning hole 41 matched with the positioning pin 11 b. The target limiting plate 4 is fixed on the front plate 11 by the cooperation of the positioning pin 11b and the positioning hole 41. In this embodiment, the target center limiting plate 4 may be made of non-metal materials such as paper and plastic, or may be made of metal materials such as aluminum foil that can be punctured. The through hole 5 is arranged on the target center limiting plate 4, and the evidence obtaining paper 6 is positioned behind the through hole 5. The part of the forensic paper 6 visible through the through-hole 5 is the part to be shot. The bulls-eye limiting plate 4 serves as a primary location for the shooter to know the general location of the shot, i.e. the portion of the forensic paper 6 that is revealed through the through-hole 5.

Further, referring to fig. 1 and 2, the evidence taking paper pulling mechanism comprises a discharging roller assembly 2 and a pulling roller assembly 3, the evidence taking paper 6 is rolled into a roll and arranged on the discharging roller assembly 2, and the pulling roller assembly 3 pulls the evidence taking paper 6 to move relative to the through hole 5. The material pulling roller assembly 3 comprises a driving roller 31 and a driven roller 32, the evidence obtaining paper 6 penetrates through the space between the driving roller 31 and the driven roller 32, and the driving roller 31 and the driven roller 32 are oppositely arranged and clamp the evidence obtaining paper 6. In the embodiment, the discharging roller assembly 2 is arranged at the upper end of the box body 1, and the pulling roller assembly 3 is arranged at the lower end of the box body 1. Referring to fig. 3, the discharging roller assembly 2 includes a supporting frame 21 and a discharging roller 22 rotatably disposed on the supporting frame 21, and the discharging roller 22 is used for discharging the evidence paper 6.

When the paper needs to be changed, the evidence obtaining paper 6 moves relative to the through hole 5 under the pulling of the evidence obtaining paper pulling mechanism. In this embodiment, the material pulling roller assembly 3 pulls the evidence obtaining paper 6 to move downwards relative to the through hole 5.

However, when the forensic paper 6 is punctured by a bullet, the forensic paper 6 swings backward by the impact force, possibly inducing several problems: 1. the discharging roller 22 passively rotates for discharging; 2. the drive roller 31 and the motor 33 are reversed; 3. the forensic paper 6 swings backwards, affecting the accuracy of image acquisition.

Therefore, referring to fig. 5, a damping assembly 23 is disposed on the supporting frame 21, the damping assembly 23 includes a spring 23a connected to the supporting frame 21 and a damping block 23b connected to the spring 23a, and the damping block 23b is pressed against the end of the discharging roller 22 under the action of the spring 23a to prevent the discharging roller 22 from being passively discharged when receiving the impact force of the bullet.

Meanwhile, the drive roll 31 is connected to a motor 33, and a transmission is provided on the motor 33 to prevent the drive roll 31 and the motor 33 from rotating reversely.

Referring to fig. 3, a evidence obtaining paper limiting groove 8 is arranged between the discharging roller assembly 2 and the drawing roller assembly 3, the evidence obtaining paper limiting groove 8 extends from the discharging roller assembly 2 to the drawing roller assembly 3, and the edge of the evidence obtaining paper 6 is clamped in the evidence obtaining paper limiting groove 8. The evidence obtaining paper limiting groove 8 can effectively limit the evidence obtaining paper 6 to swing backwards, and the accuracy of image acquisition is guaranteed.

Still further, referring to fig. 6, a bullet collecting assembly is arranged behind the box body 1, the bullet collecting assembly comprises an inclined plate 9, and a sensor for sensing that bullets reach the inclined plate 9 is arranged on the inclined plate 9. The sensor can be a vibration sensor or a sound control sensor. When the bullet strikes the evidence obtaining paper 6 and passes through the box body 1 and strikes the inclined plate 9, the inclined plate 9 vibrates and makes a sound, and the sensor senses a signal accordingly.

Referring to fig. 4, one or more cameras 7 are arranged inside the box body 1, and in practice, one or more cameras 7 can be arranged according to different precision requirements. The camera 7 lens is directed to the shot site of the forensic paper 6. Because the light is relatively weak in the box 1, when the bullet is beaten through the paper of collecting evidence 6, external light gets into the box 1 through the paper of collecting evidence 6 in, and the position of bullet hole is recorded through the position of shining on the paper of collecting evidence 6 to camera 7 in order to calculate the score of getting the target. In this embodiment, two cameras 7 are disposed inside the box body 1, wherein one camera 7 is located in the Y-axis direction of the center of the through hole 5, and the other camera 7 is located in the X-axis direction of the center of the through hole 5. By increasing the number of cameras 7, the accuracy of acquiring image information can be improved. Therefore, the number of cameras 7 is not limited to two, and a plurality of cameras may be provided.

In this embodiment, the camera 7, the sensor and the pulling roll group 3 are all connected with the control system. When the bullet passes through the evidence obtaining paper 6, the camera 7 records the position of the bullet hole, and the control system calculates the target score. The bullet then hits the ramp 9 and the sensor receives the information and passes it to the control system. Finally, the control system controls the material pulling roller group 3 to pull down the evidence obtaining paper 6 so that the shooting personnel can shoot next time.

In actual shooting training, a shooter stands in front of the front plate 11 and shoots a shot part of the forensic paper 6 displayed through the through-hole 5. After the bullet passes through the forensic paper 6, a bullet hole is left in the forensic paper 6. The camera 7 records the position of the bullet hole, and the control system calculates the target score. After the bullet enters the bullet receiving assembly and the sensor receives the information, the information is transmitted to the control system. The control system controls the drawing roller group 3 to pull down the evidence obtaining paper 6, and generally only the evidence obtaining paper 6 is pulled down by the distance of the diameter of one through hole 5. After the evidence obtaining paper 6 is pulled down, the shooter can continue shooting training.
