Abstract
Description
Technical Field
[0001] This utility model relates to the field of fireworks tube manufacturing technology, specifically a fireworks tube manufacturing machine with an anti-detachment structure. Background Technology
[0002] In the early days, the production of fireworks paper tubes relied entirely on manual labor. Workers would cut, glue, roll, and slit the paper into tubes, resulting in high labor intensity, low efficiency, inconsistent product quality, and numerous safety hazards. With the introduction of mechanical technology, simple mechanically assisted manual tube-making methods emerged, such as using a roll core to complete processes like paper unwinding, rolling, cutting, and unwinding. However, production efficiency remained limited, and the equipment was complex and inconvenient to operate. Although some tube-making machines could complete the basic processes, the connections between different processes were not tight enough. For example, the paper roll conveying could not be positioned or metered accurately, and it was prone to accidental detachment during conveying. Utility Model Content
[0003] The purpose of this utility model is to provide a fireworks production tube making machine with an anti-detachment structure to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fireworks production tube-making machine with an anti-detachment structure, comprising a paper roll, a three-phase asynchronous motor fixedly mounted on the front surface of the paper roll, a support at the bottom of the three-phase asynchronous motor, and an automatic conveying device on the right side of the paper roll, the automatic conveying device comprising:
[0005] A cutter, the top of which is fixedly mounted on the bottom of a spring, the top of which is fixedly connected to the inner side of a cutter holder, and a slide rail is provided on the inner side of the cutter holder;
[0006] A connecting rod is included, with a slider fixedly connected to one side of the connecting rod near the slide rail, and the other side of the connecting rod fixedly connected to the side of the cutter near the slide rail. The slider is slidably connected to the slide rail. The slide rail provides a precise movement trajectory for the slider. The slider, connected to the connecting rod, drives the cutter to move stably along the slide rail, ensuring the accuracy of the cutter's movement trajectory and preventing deviation or wobbling during cutting, thus improving the straightness and accuracy of the cut. The connecting rod firmly connects the cutter and the slider, ensuring stable transmission between the cutter and the slide rail system, enabling the cutter to perform cutting operations according to a predetermined path and speed, which is beneficial for achieving high-precision cutting.
[0007] A connecting plate is fixedly connected to the surface of the cutter on the side of the connecting plate away from the paper roll. An abutment plate is hinged to the other side of the connecting plate. A torsion spring is provided at the hinge point between the connecting plate and the abutment plate. A spring plate is provided on the front side of the connecting plate. An abutment rod is provided below the spring plate. The bottom of the abutment rod is fixedly installed above the table. A pressure plate is provided on the side of the abutment plate near the paper roll. A rotating shaft is fixedly connected to the side of the pressure plate near the paper roll.
[0008] Preferably, a paper roll cover is provided on the left side of the paper roll, and the bottom of the paper roll cover is connected to the side of the support. The paper roll cover can prevent the paper roll from becoming loose during use, avoiding safety hazards such as tripping over the paper roll or damaging equipment. By restricting the paper roll cover, the unfolding range of the paper roll can be controlled, preventing the paper roll from being over-unfurled, which would affect its use or cause waste.
[0009] Preferably, the left side of the table is provided with a barrel-making machine body, and the outer surface of the barrel-making machine body is provided with a motor.
[0010] Preferably, the output shaft of the three-phase asynchronous motor is fixedly connected to a rotating shaft, one end of which passes through and is fixedly connected to the paper roll; the other end of the rotating shaft is fixedly connected to a crank, and a sliding block is hinged to the end of the crank away from the paper roll.
[0011] Preferably, the surface of the tabletop is provided with a limiting groove, and a sliding block is slidably installed inside the limiting groove. The cooperation between the limiting groove and the sliding block effectively restricts the position of the paper.
[0012] Preferably, a limiting pin is provided at the top of the sliding block. The size of the paper can be effectively positioned by the limiting pin at the top of the sliding block.
[0013] Compared with the prior art, this utility model provides a fireworks production tube making machine with an anti-detachment structure, which has the following beneficial effects:
[0014] 1. This fireworks tube-making machine with an anti-detachment structure uses an automatic conveying device to drive the rotating shaft and paper roll to rotate and feed out the paper when the three-phase asynchronous motor starts. When the rotating shaft rotates, the pressure plate rotates and presses down on the connecting plate, causing the cutter to fall and cut the paper in a quantitative manner. This eliminates the need for workers to cut the paper, reduces manual intervention, lowers operating costs, reduces labor intensity, and improves production efficiency.
[0015] 2. This fireworks tube-making machine with an anti-detachment structure, when started by a three-phase asynchronous motor, drives the movement of the crank-slider mechanism. The limiting pins and limiting grooves can straighten the paper, effectively preventing the paper from falling off, increasing the stability of the machine, improving production efficiency, and reducing manual intervention.
