Description

Technical Field

[0001] The invention relates to the technical field of target changing, in particular to a lifting target changing machine. Background Art

[0002] The main equipment used in shooting is guns and ammunition, and targets (the objects to shoot at). While some professional competitive and recreational shooting events use laser ammunition and electronic targets, most shooting uses live guns and live ammunition. The targets are mostly made of paper, commonly known as target paper. Remotely changing the target paper during shooting has always been a technical challenge.

[0003] Existing technical solutions: (1) Manual target attachment. In current live-fire shooting, the target paper is mainly replaced manually by using thumbtacks, tape, etc. to fix the target paper on a target board at a certain height. (2) Slide rail target replacement. Slide rail target replacement is to fix a slide rail above the shooting point and the distant target board. Through remote control, the distant target board is slid to the shooting point to replace the target paper. In a close-range pistol shooting range, a slide rail can be laid on the ground and a mobile target vehicle can be used to transport the target to the shooting point to replace the target paper. (3) Semi-automatic manual target replacement. Two lifting targets are set at one target position in the target trench. Using a rotating or alternating lifting method, one target is on the ground and the other target is underground. The target paper is replaced manually. (4) Reel target replacement. Motors are set above and below the target. The motor drives the reel to roll and replace the target paper. A bulletproof steel plate is installed at the motor position. (5) Increase the amount of bullets received and reduce the replacement of target plates. In shock wave target and thermal imaging target reporting technology, since one target can receive thousands of bullets, a target plate made of special materials can be used to fire many bullets without having to replace it.

[0004] The disadvantages of the existing technology are that manual target changing is not very safe and the training efficiency is low. The slide rail target changing is generally suitable for close-range shooting and indoor shooting ranges. The reel-type target changing has the problem of ricocheting when installing bulletproof steel plates, which poses a great safety hazard. Semi-automatic target changing does not fundamentally solve the problems of manual use and safety. In existing shooting training, especially shooting assessments, the requirement is to save the original target paper of each shooting for viewing or review. However, the method of increasing the amount of bullets received and reducing target changes brings the problem that the shooting results cannot be traced back and reviewed. Therefore, it is necessary to provide a lifting target changing machine. Summary of the Invention

The target paper peeling surface 51 cooperates with the nail-belt synchronous belt 32 to remove the target paper 12 from the nail-belt synchronous belt 32.

[0040] The power module 6 is connected to the paper feeding module 2 and the target hanging module 3 by power;

[0041] The control circuit module 7 is electrically connected to the power module 6 and the paper feeding module 2. The control circuit module 7 controls the power module 6 to provide power to the paper feeding module 2 and the target hanging module 3. The control circuit module 7 controls the lifting and lowering of the lifting module 4. The control circuit module 7 controls the paper feeding module 2 to cut the target paper 12. The user can remotely control the control circuit module 7 through a remote control, which is convenient to use and safer to change targets.

[0042] The frame 8 is provided with a paper tube holder 1, a paper feeding module 2 and a lifting module 4 from left to right in sequence. The frame 8 is also provided with a power module 6 and a control circuit module 7.

After the shooting is completed, the control circuit module 7 controls the lifting device 4 to drive the target hanging module 3 to move downward. Then the control circuit module 7 controls the power module 6 to drive the nail-carrying synchronous belt 32 to move downward. The movable paper guide 33 deviates downward under the traction of the target paper 12, so that the used target paper 12 moves in the direction of the nail-carrying synchronous belt 32, so that the bottom end of the used target paper 12 is away from the paper feeding module 2. The used target paper 12 is guided by the movable paper guide 33 to the target sleeve paper guide groove 5. The used target paper 12 continues to move downward under the drive of the nail-carrying synchronous belt 32. The inclined target paper peeling surface 51 gradually separates the used target paper 12 from the nail-carrying synchronous belt 32 and guides it out from the target paper guide surface 52.

Under the action of the tension spring 214, the paper release guide spring plate 212 is tightly attached to the pickup roller 22. The pickup roller 22 rotates and drives the target paper 12 to move toward the target hanging module 3. The target paper 12 is guided to the nail-belted synchronous belt 32 by the second unpowered roller 241, the paper feed guide lower plate 242 and the paper feed guide upper plate 243. When the color mark on the target paper 12 runs to the color mark sensor At 232, the color mark sensor 232 transmits a signal to the control circuit module 7, the control circuit module 7 controls the power module 6 to stop and starts the paper cutting motor 234, the paper cutting motor 234 drives the first paper cutting slider synchronous wheel 237 to rotate, the first paper cutting slider synchronous wheel 237 drives the paper cutting slider belt 239 to move, the second paper cutting slider synchronous wheel assists the paper cutting slider belt 239 to move, the paper cutting slider belt 239 drives the paper cutting slider 235 to move on the track 231, and the paper cutting slider 235 drives the paper cutting blade 236 to cut the target paper 12.

The photoelectric sensors 233 cooperate with the connecting block 37 and are electrically connected to the control circuit module 7. The elevator 41 drives the target hanging frame 31 up and down through the connecting block 37. When the connecting block 37 touches the photoelectric sensors 233 at the top and bottom of the elevator 41, the photoelectric sensors 233 transmit signals to the control circuit module 7, which controls the elevator 41 to stop.

Several target plate fixing nails 318 are provided on the inner side of the target rod 312, and the target plate 316 passes through the gaps between the several target plate fixing nails 318 and is inserted into the target plate mounting groove 317. The removable target rod 312 is easy to remove and transport. The ends of the L-shaped mounting plate 314 are fixed between the two target rods 312 by two mutually perpendicular mounting pins 315. The target plate 316 is inserted into the target plate mounting slot 317 through the gaps between several target plate fixing pins 318. The target rod 312 is made of aluminum alloy, taking into account the barbs that form when hit by bullets. Bullets can penetrate smoothly and operate normally after penetration without ricocheting. This high safety ensures that the target rod can still be used after a large number of bullets are hit. The synchronous belt is not easily broken after live-fire testing. The aluminum alloy target rod material has a very high bullet resistance. As long as the bullet does not hit the synchronous wheel at the top of the target rod, the target rod can be used normally.
