Technical Field

[0001] The utility model relates to the field of fireworks processing, in particular to a device for punching holes on the side wall of cylindrical fireworks. Background Art

[0002] Fireworks generally include an outer cylindrical paper tube and a cylindrical firework tube. The side walls of the paper tube and the firework tube need to be punched. Only after the holes are punched can the fuse be inserted into the paper tube and the firework tube.

[0003] When punching, the existing punching device directly moves an impact rod downward to punch a hole on the side of the firework tube. However, there will be burrs on the hole directly punched in the firework tube, which is not convenient for trimming the burrs. In addition, the punching position of the firework tube is prone to some deformation, which makes the hole opening effect of the firework tube not good enough. Utility Model Content

[0004] In order to overcome the shortcomings of existing equipment that the holes punched on the firework tube will have burrs and some deformation at the punching position of the firework tube, thereby resulting in an insufficient hole opening effect of the firework tube, the utility model provides a cylindrical firework side wall punching device that can trim the holes on the side of the firework tube and reshape the firework tube, thereby achieving a better hole opening effect of the firework tube.

[0005] The technical implementation scheme of the utility model is: a cylindrical fireworks side wall punching device, including a support seat, a support roller, a support frame, a clamping frame, a tension spring, an electric push rod and a transmission rod, one side of the support seat is fixedly connected to the support roller, the support roller is provided with a through hole, the support roller is sleeved with a fireworks tube, the support seat is fixedly connected to the support frame, the support frame is slidably connected to the clamping frame, the clamping frame is provided with a round hole, the other side of the support seat is fixedly connected to the electric push rod, the transmission rod is fixedly connected to the telescopic rod of the electric push rod, the clamping frame is slidably connected to the transmission rod, and a tension spring is connected between the clamping frame and the transmission rod.

[0006] Optionally, it also includes an impact rod, a rotating threaded sleeve, a guide frame and a grinding ring. The impact rod is rotatably connected to the transmission rod, the rotating threaded sleeve is fixedly connected to the impact rod, the top of the support seat is fixedly connected to the guide frame, the guide frame and the rotating threaded sleeve are threadedly connected, and the lower end of the impact rod is fixedly connected to the grinding ring.

[0007] Optionally, it also includes a connecting rod, a rubber block, a guide rod, a pushing frame and a contact rod frame, the connecting rod is fixedly connected to the transmission rod, the rubber block is fixedly connected to the lower part of the connecting rod, the guide rod is fixedly connected to the top of the support frame, the pushing frame is slidably connected to the guide rod, the top of the pushing frame is provided with a plurality of inclined surfaces, the contact rod frame is fixedly connected to the transmission rod, and the contact rod frame contacts with one of the inclined surfaces of the pushing frame.

[0008] Optionally, a guide plate is also included, and the support roller is fixedly connected with the guide plate, and the guide plate is arranged at an angle.

[0009] Compared with the prior art, the utility model has the following advantages: 1. The transmission rod continues to move downward to compress the tension spring, and the pressure generated by the compression of the tension spring fixes the firework tube through the clamping frame. The impact rod and the grinding ring move downward while rotating. The impact rod and the grinding ring move downward to make a hole on the side of the firework tube, and the rotation of the grinding ring will trim the hole on the side of the firework tube, so that the hole opening effect of the firework tube is better.

[0010] 2. When the clamping frame is reset, it will first break contact with the firework tube. Then, when the connecting rod and the rubber block are reset, they will contact the firework tube to make the firework tube rotate. When the contact rod frame is reset, it will contact the pushing frame and push the pushing frame to move. The movement of the pushing frame will push the clamping frame downward. The downward movement of the clamping frame will contact the firework tube. As the firework tube rotates, the holes on the side of the firework tube no longer contact the round holes of the clamping frame and the through holes of the support roller. The clamping frame presses the firework tube onto the support roller to further reshape the holes on the side of the firework tube, thereby further improving the hole opening effect of the firework tube.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Embodiment 1: A cylindrical fireworks side wall punching device, such as Figure 1-Figure 4 As shown, it includes a support seat 1, a support roller 2, a support frame 4, a clamping frame 5, a tension spring 6, an electric push rod 7 and a transmission rod 8.

[0019] It also includes an impact rod 9, a rotating threaded sleeve 10, a guide frame 11 and a grinding ring 12. The impact rod 9 is rotatably connected to the transmission rod 8. The impact rod 9 is above the through hole of the support roller 2 and the circular hole of the clamping frame 5. The impact rod 9 is welded with a rotating threaded sleeve 10. The top of the support seat 1 is fixedly connected with the guide frame 11. The guide frame 11 is connected to the rotating threaded sleeve 10 through threads. The lower end of the impact rod 9 is fixedly connected with a grinding ring 12, and the grinding ring 12 is used to grind the hole of the firework tube 3.

[0020] At first, the transmission rod 8 pulls the tension spring 6, so that the tension spring 6 is in a tensioned state. The staff puts a firework tube 3 on the support roller 2, and the staff starts the electric push rod 7. The contraction of the telescopic rod of the electric push rod 7 will drive the transmission rod 8 to move downward. The downward movement of the transmission rod 8 will drive the impact rod 9, the rotating threaded sleeve 10 and move downward. The downward movement of the rotating threaded sleeve 10 will cause the threads on the rotating threaded sleeve 10 to be squeezed by the guide frame 11, so that the rotating threaded sleeve 10 rotates. The rotation of the rotating threaded sleeve 10 will drive the impact rod 9 and the grinding ring 12 to rotate. At the same time, the downward movement of the transmission rod 8 will reset the tension spring 6. The transmission rod 8 continues to move downward, which will drive the pressing frame 5 to move downward through the tension spring 6. The pressing frame 5 moves downward and contacts with the firework tube 3. The transmission rod 8 continues to move downward, which will compress the tension spring 6. The pressure generated by the compression of the tension spring 6 will push the firework tube 3 through the pressing frame 5. The firework tube 3 is fixed, and the impact rod 9 and the grinding ring 12 move downward while rotating. The impact rod 9 and the grinding ring 12 move downward and pass through the round hole of the pressing frame 5, and then the impact rod 9 and the grinding ring 12 move downward to punch a hole on the side of the firework tube 3, and then the impact rod 9 and the grinding ring 12 move downward and pass through the through hole of the supporting roller 2, and the shredded paper punched out by the firework tube 3 falls into the supporting roller 2, and the rotation of the grinding ring 12 will trim the hole on the side of the firework tube 3, so that the hole opening effect of the firework tube 3 is better. After the drilling is completed, the telescopic rod of the electric push rod 7 rises to drive the transmission rod 8 to move upward, and the transmission rod 8 moves upward to drive the impact rod 9, the rotating threaded sleeve 10 and the grinding ring 12 to reset, and at the same time, the transmission rod 8 moves upward to drive the tension spring 6 to reset, and the transmission rod 8 continues to move upward to drive the tension spring 6 and the pressing frame 5 to reset, and the tension spring 6 is reset to stretch the tension spring 6.

[0021] Embodiment 2: Based on embodiment 1, Figure 2-Figure 5 As shown, it also includes a connecting rod 13, a rubber block 14, a guide rod 15, a pushing frame 16 and a contact rod frame 17. The connecting rod 13 is welded on the transmission rod 8, and the rubber block 14 is fixedly connected to the lower part of the connecting rod 13. The guide rod 15 is welded on the top of the support frame 4, and the pushing frame 16 is slidably connected to the guide rod 15. The top of the pushing frame 16 is provided with several inclined surfaces, and the contact rod frame 17 is welded on the transmission rod 8, and the contact rod frame 17 is in contact with one of the inclined surfaces of the pushing frame 16.

[0022] The transmission rod 8 moves downward, which drives the connecting rod 13, the rubber block 14 and the contact rod frame 17 to move downward. The contact rod frame 17 moves downward, which drives the pushing frame 16 to move. The pushing frame 16 moves, which drives the pressing frame 5 to move downward. The pressing frame 5 moves downward and contacts the firework tube 3. The pressing frame 5 moves downward, which keeps the tension spring 6 in a tensioned state. The contact rod frame 17 continues to move, which disengages from the pushing frame 16. The pressing frame 5 moves upward under the drive of the tension spring 6. The pressing frame 5 moves upward, which contacts the pushing frame 16 and pushes the pushing frame 16 to reset. At the same time, the connecting rod 13 and the rubber block 14 move downward, which contacts the firework tube 3. The rubber block 14 moves downward, which drives the firework tube 3 to rotate. The rubber block 14 disengages from the firework tube 3. Then the transmission rod 8 continues to move downward, which moves the pressing frame 5 downward and contacts the firework tube 3. 5. The connecting rod 13, the rubber block 14 and the contact rod frame 17 are reset. The pressing frame 5 will first be out of contact with the firework tube 3 when it is reset. Then the connecting rod 13 and the rubber block 14 will be reset to contact with the firework tube 3 to make the firework tube 3 rotate. The contact rod frame 17 will be reset to contact with the pushing frame 16 and push the pushing frame 16 to move. The movement of the pushing frame 16 will push the pressing frame 5 to move downward. The downward movement of the pressing frame 5 will further stretch the tension spring 6. The downward movement of the pressing frame 5 will contact the firework tube 3. Due to the rotation of the firework tube 3, the holes opened on the side of the firework tube 3 are no longer in contact with the round holes of the pressing frame 5 and the through holes of the supporting roller 2. The pressing frame 5 presses the firework tube 3 on the supporting roller 2 to further reshape the holes on the side of the firework tube 3, so as to further improve the opening effect of the firework tube 3. The contact rod frame 17 will continue to reset to be out of contact with the pushing frame 16, and the tension spring 6 will drive the pressing frame 5 to reset.
