[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] A packaging carton drop test device, such as Figures 1-10 As shown, it includes an outer shell 1, a bearing seat 2 is fixedly installed at the bottom end of the inner shell 1, a fixed frame 4 is fixedly installed at the bottom end of the inner shell 1, a reciprocating screw 5 is rotatably connected inside the fixed frame 4, a motor 1 is installed on the upper end surface of the outer shell 1, and the output end of the motor 1 is connected to the reciprocating screw 5, a movable block 6 is sleeved on the outside of the reciprocating screw 5, one end of the movable block 6 is fixedly connected to a bearing plate 7, a fixing mechanism is provided on the outer wall of the bearing plate 7, a movable door 3 is connected to the front end surface of the bearing seat 2 through a hinge, a protective mechanism is provided on the front end surface of the outer shell 1 near the upper end, the fixing mechanism includes a turntable 8, the turntable 8 is rotatably connected to the outer wall of the bearing plate 7, an annular groove 17 is provided on the front end surface of the bearing plate 7, a plurality of sliding blocks 18 are slidably connected inside the annular groove 17, and one end of the plurality of sliding blocks 18 are fixedly connected to the turntable 8.

[0033] A fixing frame 16 is fixedly connected to the bottom surface of the carrying plate 7, and the inner wall of the fixing frame 16 is rotatably connected to the gear 2 15 through a shaft. A motor 2 is installed on the front end surface of the fixing frame 16, and the output end of the motor 2 is connected to the gear 2 15 through a shaft. A plurality of tooth grooves are provided on the outer wall of the turntable 8, and the plurality of tooth grooves are meshed with the gear 2 15. When the turntable 8 rotates, the sliding block 18 follows the turntable 8 and moves along the annular groove 17, thereby limiting the rotation position of the turntable 8 and preventing the turntable 8 from falling off the carrying plate 7.

[0034] Two L-shaped connecting plates 9 are fixedly connected to the outer wall of the turntable 8, and two sliding rods 10 are fixedly connected between the inner walls of the two L-shaped connecting plates 9. Two splints 11 are sleeved between the outsides of the two sliding rods 10. Two racks 14 are inserted into the outer walls of the turntable 8, and the two racks 14 are slidably connected to the inner wall of the turntable 8. A mounting plate 12 is fixedly installed inside the turntable 8, and the outer wall of the mounting plate 12 is rotatably connected to gear 13 through an axis rod. Motor three is installed on the other outer wall of the mounting plate 12, and the output end of motor three is connected to gear 13 through an axis rod, and gear 13 and the two racks 14 are meshed with each other. One end of the two racks 14 is fixedly connected to the two splints 11 respectively, and motor three drives gear 13 to rotate, thereby driving the two racks 14 to move laterally, driving the two splints 11 to move along the outside of the two sliding rods 10 and approach each other, so that the test carton can be clamped and fixed.

[0035] During use, the carton to be tested is placed between the two clamping plates 11, and then the motor 3 installed on the mounting plate 12 drives the gear 13 to rotate, thereby driving the two racks 14 to move laterally, driving the two clamping plates 11 to move along the outside of the two slide bars 10 and close to each other, so that the carton to be tested can be clamped and fixed. After the clamping is fixed, the motor 2 on the fixing frame 16 can drive the gear 2 15 to rotate, and cooperate with each tooth groove to drive the turntable 8 to rotate through the sliding block 18 and the annular slide groove 17, thereby driving the clamping plates 11 connected by the L-shaped connecting plate 9 and the carton clamped between the two clamping plates 11 to rotate, so that the placement angle of the carton can be adjusted, which is convenient for drop tests of cartons at different angles.

[0036] After the carton is fixed, the reciprocating screw 5 in the fixed frame 4 is driven to rotate by motor 1, thereby driving the movable block 6 to move up along the reciprocating screw 5, thereby driving the supporting plate 7 to move up, and then driving the carton to the required height. Then, similarly, motor 2 cooperates with gear 1 13 to rotate in the opposite direction, so that the two clamping plates 11 can be moved away from each other, releasing the clamping of the carton, allowing the carton to fall under the action of gravity for a drop test.

[0037] The protective mechanism includes a winding roller 19, which is rotatably connected to the front end surface of the shell 1 and close to the upper end. A motor is installed on the outer wall of the shell 1, and the output end of the motor is connected to the winding roller 19. A transparent curtain 20 is wrapped around the outside of the winding roller 19. The free end of the transparent curtain 20 is fixedly connected to a counterweight bar 24, and the outer wall of the counterweight bar 24 is fixedly connected to an L-shaped plug plate 21 near both ends.

[0038] The outer walls of the two L-shaped plug plates 21 are both provided with movable grooves, and a card block 22 is inserted into the movable groove. Several spring pieces 23 are fixedly connected between one end of the card block 22 and the inner wall of the movable groove. Slots 25 are provided on the upper end surface of the bearing seat 2 near both sides, and the slots 25 fit with the L-shaped plug plates 21. The inner walls of the two slots 25 are both provided with card slots 26, and the card slots 26 fit with the card block 22. Under the elastic force of the spring piece 23, the counterweight bar 24 can be driven to fit into the card slot 26, thereby fixing the position of the L-shaped plug plate 21 in the card slot 26.

[0039] Specifically, after the carton is fixed in the shell 1, before the drop test is carried out, the motor can be used to drive the winding roller 19 to rotate, so that the transparent curtain 20 wound on the winding roller 19 is loosened, and under the action of the gravity of the counterweight bar 24, one end moves downward, so that the transparent curtain 20 is unfolded on the front surface of the shell 1 to seal the shell 1, and the staff can insert one end of the L-shaped plug-in plate 21 into the slot 25. During the insertion process, the card block 22 moves with the L-shaped plug-in plate 21. The inclined surface of the card block 22 first contacts the inner wall of the counterweight bar 24 and moves along the inside of the counterweight bar 24, which can make the counterweight bar 24 gradually shrink into the movable groove, and each spring sheet 23 is compressed until one end of the L-shaped plug-in plate 21 After being fully inserted, the card block 22 is located at one side of the card slot 26. At this time, under the elastic force of the spring sheet 23, the card block 22 can be driven to be clamped into the card slot 26, and the position of the L-shaped plug plate 21 is fixed in the card slot 26, thereby fixing the position of the counterweight bar 24 on the upper surface of the bearing seat 2 and the movable door 3, fixing the unfolded transparent curtain 20, thereby fully blocking the front end surface of the shell 1, and cooperating with the shell 1 to block the entire drop test area, preventing the carton from accidentally falling out of the test area when falling and accidentally injuring the staff. Moreover, since the transparent curtain 20 is made of transparent material, the staff can observe the entire drop test through the counterweight bar 24, and the movable door 3 can be opened to take out the carton after the test;

[0040] The test device can be sealed by the shell 1 in combination with the transparent curtain 20, so that when the test device is not in use, it can be shielded and protected to prevent the device from being affected by moisture and dust.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
