Abstract
Description
Technical Field
[0001] The present invention relates to the production processes of firecrackers and fireworks, and is a paper tube clamp in the automated production of firecrackers and fireworks. Background Art
[0002] Before the present invention, the production of firecrackers and fireworks adopted a dry powder gunpowder production process and a fuzzy charging method. That is, hundreds of firecracker paper tubes were bundled into a hexagonal cake shape, and then dry powder gunpowder with a corresponding thickness was laid on the hexagonal paper tube cake according to the gunpowder amount of the firecrackers. The above method has inaccurate charge amounts, is unsafe, not environmentally friendly, and it is difficult to achieve an automated production process. The present invention is a paper tube clamp developed for the wet gunpowder production process of firecrackers. This clamp clamps the firecracker paper tubes individually in groups, realizing the filling of wet gunpowder into individual paper tubes, effectively solving the problems of safety, environmental protection, and automated production in the production of firecrackers and fireworks. Summary of the Invention
[0003] Since the automated production process of firecrackers and fireworks uses wet gunpowder, the paper tubes need to meet the production processes such as charging, sealing, and injecting primer. The paper tubes move step by step on the production line. To solve the movement of the paper tubes, a paper tube clamp is developed. It is composed of two clamping plates that open and close to clamp the paper tubes. Its characteristics are that the opening and closing of the clamping plates are composed of a lead screw, a positive and negative nut, a synchronous gear, a rack, a clamping plate support slider, a guide rail, a clamp base, etc. Pushing the synchronous rack to drive the synchronous gear can realize the simultaneous opening and closing of the two clamping plates, keeping the center of the paper tube from shifting.
[0004] The key points of the invention are as follows:
[0005] 1. The two clamping plates open and close simultaneously, keeping the center of the paper tube from shifting.
[0006] 2. The rotation angles of the synchronous gears should be consistent, and the clamping tightness should not be inconsistent.
[0007] 3. The holes in the clamping plates should be smaller than the outer diameter of the paper tubes to ensure clamping of the paper tubes.
[0008] The advantages of the present invention are as follows:
[0009] 1. The power of the clamp is separated from the clamp body, and the movement does not need to drive components such as cylinders and motors, which is beneficial to the cyclic step-by-step process.
[0010] 2. The clamp clamps the paper tubes individually in a row and moves the whole row, meeting the high-efficiency production process.
[0011] 3. When multiple clamps move in a coordinated and step-by-step manner, multiple working stations such as filling wet gunpowder, sealing, and injecting primer can be completed simultaneously. Brief Description of the Drawings
[0012] Figure 1It is a three-dimensional drawing of a paper tube clamp and also the abstract drawing. Figure 1 In it, 1 is the clamping plate, and 2 is the fixture base. Figure 2 It is the structure diagram of the fixture excluding the clamping plate base. In the figure, 3 and 12 are the forward and reverse lead screw bearing seats, 4 and 13 are the positive and negative nuts, 5 is the clamping plate support slider, 6 is the slider track, 7 is the forward and reverse lead screw, 8 is the fixture positioning hole, 9 is the rack adjusting rod support seat, 10 is the rack adjusting rod, 11 is the synchronous rack, and 14 is the synchronous gear. Figure 3 It is a three-dimensional drawing of the paper tube clamping situation. In the figure, 15 is the firecracker paper tube. The working principle is: an external force pushes the rack adjusting rod, the rack moves, the synchronous gear and the forward and reverse lead screw rotate, the positive and negative nuts move to drive the clamping plate to open and close, and the opening and closing of the clamping plate achieve the purpose of clamping the paper tube. Specific implementation method
[0013] 1. Case Figure 1 Install the mechanical accessories.
[0014] 2. Adjust the rack adjusting rod to make the synchronous gear rotate synchronously.
[0015] 3. Adjust the position of the positive and negative nuts so that when the forward and reverse lead screw rotates, the positive and negative nuts move synchronously and the clamping plate opens and closes smoothly.
[0016] 4. Apply external forces to both ends of the rack adjusting rod respectively to push and debug the smooth opening and closing of the clamping plate.
[0017] Conclusion: This implementation method achieves the invention purpose.
