[0001] The utility model belongs to the technical field of firework paper tube detection, and particularly relates to a strength inspection device for firework and firecracker paper tubes. Background Technique

[0002] Fireworks and firecrackers refer to entertainment products mainly made of pyrotechnic compositions. Generally, black powder is used as the propellant. The black powder is mixed with many small grains and filled into a paper tube to form a firework flame tube. After ignition, it burns or explodes, accompanied by effects such as sound, light, color, smoke, and fog. The explosion effect produced when fireworks and firecrackers are set off has certain risks. Therefore, the quality of the firework and firecracker paper tube has a very important impact on the safety of fireworks and firecrackers. During the production process of fireworks and firecrackers, it is necessary to use an inspection device to detect the strength of the firework and firecracker paper tubes.

[0003] Due to the large variety of fireworks and firecrackers, the specifications of the firework and firecracker paper tubes are also different. When the existing inspection devices inspect the firework and firecracker paper tubes, it is mostly difficult to inspect the firework and firecracker paper tubes with different diameter specifications, and the applicability is poor. When inspecting the firework and firecracker paper tubes, the paper tube is usually placed on the inspection device. When the paper tube is subjected to an external pressure, the firework and firecracker paper tube is very likely to move, which greatly affects the inspection efficiency and also results in inaccurate inspection data.

[0004] Therefore, a strength inspection device for firework and firecracker paper tubes is needed to solve the problems in the prior art that the inspection device is not easy to fix the firework and firecracker paper tubes with different diameters, and the firework and firecracker paper tubes are prone to move when stressed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present utility model in conjunction with embodiments.

[0022] Please refer to Figures 1-4, the utility model provides a strength inspection device for fireworks paper tubes, including a support platform 1. A U-shaped seat 2 is fixedly connected to the top surface of the support platform 1. A fixed frame 3 is fixedly connected to the top surface of the U-shaped seat 2. Slide grooves 4 are opened on both inner walls of the fixed frame 3. The same cross bar 5 is slidably connected between the two slide grooves 4. A display screen 6 is installed on one side of the outer wall at one end of the fixed frame 3. Two groups of fixing mechanisms 7 distributed in parallel are arranged on the inner bottom surface of the U-shaped seat 2;

[0023] The fixing mechanism 7 includes a mounting seat 71. The bottom surface of the mounting seat 71 is fixedly connected to the inner bottom surface of the U-shaped seat 2. A T-shaped groove 72 is opened on the top surface of the mounting seat 71. A driving motor 73 is fixedly connected to the outer wall of one side of the mounting seat 71 corresponding to the T-shaped groove 72. The output end of the driving motor 73 is coaxially fixedly connected with a bidirectional threaded rod 74. The outer wall of the bidirectional threaded rod 74 away from the driving motor 73 rotates through the outer wall of one side of the mounting seat 71 and is rotatably connected to the inner side wall of the T-shaped groove 72. Two symmetrically distributed T-shaped sliders 75 that cooperate with the T-shaped groove 72 are threadedly connected to the outer surface of the bidirectional threaded rod 74. A clamping block 76 is fixedly connected to the top surface of the T-shaped slider 75. The same limiting component 77 is arranged on the two clamping blocks 76.

[0024] Further, as Figure 4 shown, it is worth specifically explaining that the limiting component 77 includes a U-shaped plate 771 and a rectangular block 772. The U-shaped plate 771 is arranged vertically and the outer wall of one side is fixedly connected to the outer wall of one of the clamping blocks 76. The outer wall of one side of the rectangular block 772 is fixedly connected to the outer wall of the other clamping block 76. A pull ring 773 is rotatably connected between the inner walls at both ends of the U-shaped plate 771. A plug board 774 is fixedly connected to the bottom surface of the pull ring 773 away from the U-shaped plate 771. A slot 775 that cooperates with the plug board 774 is opened through the top surface of the rectangular block 772. A locking screw 776 is inserted through a threaded hole on the outer wall of the rectangular block 772 away from the clamping block 76. A clamping plate 777 is rotatably connected to the shaft end of the locking screw 776.

[0025] Further, as Figure 1 and Figure 2 shown, it is worth specifically explaining that a forward and reverse motor 8 is fixedly connected to one side of the top surface of the fixed frame 3. The output end of the forward and reverse motor 8 is coaxially fixedly connected with a threaded screw rod 9. The bottom end of the threaded screw rod 9 rotates through the top surface of the fixed frame 3 and is rotatably connected to the inner bottom surface of a corresponding slide groove 4. A guide rod 10 is fixedly connected between the inner top surface and the inner bottom surface of the other slide groove 4.

[0026] Further, as Figure 1 and Figure 2As shown, it is worth specifically explaining that a hydraulic cylinder 11 is fixedly connected to the center of the top surface of the cross bar 5. The output end of the hydraulic cylinder 11 slidably penetrates the bottom surface of the cross bar 5 and is coaxially fixedly connected to a lower pressing plate 12. A pressure sensor 13 electrically connected to the display screen 6 is installed at the bottom end of the lower pressing plate 12.

[0027] Further, as Figure 4 shown, it is worth specifically explaining that the insertion plate 774 is inserted into the inside of the slot 775 and a plurality of evenly distributed clamping slots are formed on one outer wall. The clamping plate 777 is embedded in one side of the insertion plate 774 through the clamping slots. The locking screw rod 776 drives the clamping plate 777 to move. With the cooperation of the clamping plate 777 and the clamping slots on the insertion plate 774, the pull ring 773 is locked and fixed.

[0028] Further, as Figure 2 shown, it is worth specifically explaining that the threaded lead screw 9 is threadedly connected to the cross bar 5, and the guide rod 10 is slidably connected to the cross bar 5. The forward and reverse motor 8 drives the threaded lead screw 9 to rotate, so as to realize the up and down movement of the cross bar 5.

[0029] In summary: When the fireworks and firecrackers paper tube strength inspection device is in use, first, the forward and reverse motor 8 is started to drive the threaded lead screw 9 to rotate. Under the action of the thread, the cross bar 5 moves downward in the chute 4 to initially adjust the position of the lower pressing plate 12. Then, the operator places the two ends of the fireworks and firecrackers paper tube to be inspected between the two clamping blocks 76 in the two fixing mechanisms 7 respectively. Then, the driving motor 73 is started to drive the bidirectional threaded rod 74 to rotate. Under the action of the thread, the two T-shaped sliders 75 on the mounting seat 71 approach each other in the T-shaped groove 72, thereby driving the two clamping blocks 76 to approach each other. The two fixing mechanisms 7 work simultaneously, so that the four clamping blocks 76 respectively clamp the outer surfaces on both sides of the fireworks and firecrackers paper tube, thereby realizing the fixation of the fireworks and firecrackers paper tube. The operation is simple, effectively avoiding the problem that the inspection device is not easy to fix fireworks and firecrackers paper tubes with different diameters.

[0030] After the fireworks paper tube is clamped and fixed, the operator pulls the pull ring 773 to rotate it. After pulling the pull ring 773 to cover the outside of the fireworks paper tube, the insertion plate 774 on the pull ring 773 is inserted into the slot 775 on the rectangular block 772. Then, the locking screw 776 is rotated. Under the action of the thread, the locking screw 776 pushes the clamping plate 777 to move towards the direction of the insertion plate 774. Through the cooperation of the clamping plate 777 and the slots on the insertion plate 774, the pull ring 773 is locked and fixed. The two pull rings 773 are operated in sequence to realize the restraint and limit of the fireworks paper tube. Finally, the hydraulic cylinder 11 is controlled to push the lower pressing plate 12 to press down. The lower pressing plate 12 drives the pressure sensor 13 to contact the fireworks paper tube. As the lower pressing plate 12 continues to press down, the operator can obtain the inspection result of the fireworks paper tube through the deformation degree of the fireworks paper tube and the data displayed on the display screen 6. Under the action of the limiting component 77, the fireworks paper tube will not move when stressed, improving the accuracy of the inspection data of the fireworks paper tube and effectively avoiding the problem that the fireworks paper tube is prone to move when stressed, thus affecting the inspection effect.

[0031] The driving motor 73 and the forward and reverse motor 8 can be purchased on the market. The driving motor 73 and the forward and reverse motor 8 are equipped with power supplies, which are mature technologies in the field and have been fully disclosed. Therefore, they are not repeated in the specification.
