Description

Technical Field

[0001] The utility model relates to the technical field of fireworks production, and particularly relates to a film sealing device for fireworks production. Background Art

[0002] During the production of fireworks, it is necessary to seal the top end of the barrel so that chemical substances such as gunpowder in the barrel can be stored for a longer time. By arranging and bonding single barrels in sequence, single barrels are made into combined fireworks. With the increasing demand for fireworks, fireworks factories use fireworks film sealing machines to replace traditional manual sealing, thereby improving the film sealing efficiency.

[0003] However, when the existing film sealing device seals the fireworks barrel, due to local protrusions and uneven surfaces at both ends of the fireworks barrel, the sealed film is damaged, and the substances inside the fireworks barrel cannot be effectively stored. The prior art grinds the ends of the fireworks barrel before film sealing to make its ends flat. However, the prior art grinds the two ends separately, resulting in low grinding efficiency and reduced production efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a film sealing device for fireworks production to solve the above deficiencies in the prior art.

[0025] Please refer to Figures 1-5 , a film sealing device for fireworks production, including a machine case 5, on which two symmetrically arranged film sealing mechanisms are provided; a feeding component 1 is provided on the machine case 5, the feeding component 1 includes a plurality of steps 11 arranged on the machine case 5, each of the steps 11 is inclined, and a lifting plate 12 is further slidably connected in each of the steps 11, and the lifting plate 12 is connected to the driving component; a telescopic component 3 is further provided on the machine case 5, both ends of the telescopic component 3 are respectively rotatably connected to a first grinding disc 41 and a second grinding disc 42, and the rotation directions of the first grinding disc 41 and the second grinding disc 42 are opposite. The first grinding disc 41 and the second grinding disc 42 are respectively driven by a first motor and a second motor, and the first motor and the second motor are installed on the telescopic component 3.

[0026] Through the provided feeding component 1, under the action of the driving component, each lifting plate 12 jacks up the firework cylinder to the upper-level step to complete the feeding of the firework cylinder. Through the provided telescopic component 3, when the firework cylinder moves to the positions of the first grinding disc 41 and the second grinding disc 42, the telescopic component 3 drives the first grinding disc 41 and the second grinding disc 42 to abut against both ends of the firework cylinder and rotate in opposite directions, while grinding both ends of the firework cylinder. After the grinding is completed, the firework cylinder moves to the film sealing mechanism under the action of the feeding component 1 for film sealing, thereby completing the film sealing of the firework cylinder.

[0027] Further, the driving assembly includes a hydraulic cylinder 21 fixedly arranged in the chassis 5. A connecting part 22 is fixedly connected to the driving end of the hydraulic cylinder 21. The connecting part 22 is fixedly connected to each lifting plate 12. The connecting part 22 includes a connecting rod 221. A vertical groove 222 is arranged on the connecting rod 221. A fixing rod 223 is fixedly connected to the end of the hydraulic cylinder 21. The fixing rod 223 is slidably connected in the vertical groove 222. A connecting plate 224 is fixedly connected to the end of the connecting rod 221. The connecting plate 224 is slidably connected in the chassis 5. The connecting plate 224 is fixedly connected to each lifting plate 12.

[0028] The hydraulic cylinder 21 drives the fixing rod 223 to move horizontally. The movement of the fixing rod 223 drives the connecting rod 221 to move through the vertical groove 222. The movement of the connecting rod 221 drives the connecting plate 224 to move. The movement of the connecting plate 224 drives each lifting plate 12 to move simultaneously.

[0029] Further, the telescopic assembly 3 includes two sliding rods 31 slidably connected to the chassis 5. A positioning rod 32 is fixedly arranged at one end of the sliding rods 31 close to each other. The positioning rod 32 is slidably connected in a chute 33 on the connecting plate 224, so that the connecting plate 224 drives the sliding rods 31 to move towards or away from each other. An installation plate 34 is fixedly connected to the other end of the sliding rods 31 away from each other. The first grinding disc 41 and the second grinding disc 42 are respectively rotatably connected to the two installation plates 34. The chute 33 is arranged in a shape of an inverted V or a V. The first motor and the second motor are respectively fixedly arranged on the installation plate 34.

[0030] When the chute 33 is in the shape of an inverted V, the connecting plate 224 moves downward. The chute 33 on the connecting plate 224 drives the two sliding rods 31 to move towards each other through the positioning rod 32. The sliding rods 31 drive the installation plate 34 to move. The movement of the installation plate 34 drives the corresponding first grinding disc 41 and the second grinding disc 42 to move towards each other, so as to abut against both ends of the fireworks tube. The first grinding disc 41 and the second grinding disc 42 rotate in opposite directions to polish both ends of the fireworks tube simultaneously. It should be noted that the clamping of the first grinding disc 41 and the second grinding disc 42 on the fireworks tube is after the lifting plate 12 retracts into the step 11 and the fireworks tube falls inside the step 11.

[0031] When the chute 33 is in the shape of a V, the connecting plate 224 moves upward. The chute 33 on the connecting plate 224 drives the two sliding rods 31 to move towards each other through the positioning rod 32. The movement of the sliding rods 31 drives the first grinding disc 41 and the second grinding disc 42 to move towards each other, so that the first grinding disc 41 and the second grinding disc 42 rotate in opposite directions to polish both ends of the fireworks tube simultaneously. It should be noted that the clamping of the first grinding disc 41 and the second grinding disc 42 on the end of the fireworks tube is after the lifting plate 12 jacks up the fireworks tube to the upper-level step 11.

[0032] Working principle:

[0033] The hydraulic cylinder 21 drives the fixed rod 223 to move horizontally. The movement of the fixed rod 223 drives the connecting rod 221 to move through the vertical groove 222. The movement of the connecting rod 221 drives the connecting plate 224 to move. The movement of the connecting plate 224 drives each lifting plate 12 to move simultaneously, and each lifting plate 12 jacks up the fireworks cylinder to the upper-level step to complete the feeding of the fireworks cylinder. Through the arranged telescopic assembly 3, when the fireworks cylinder moves to the first grinding disc 41 and the second grinding disc 42, the telescopic assembly 3 drives the first grinding disc 41 and the second grinding disc 42 to abut against both ends of the fireworks cylinder and rotate in the reverse direction, while grinding both ends of the fireworks cylinder. After the grinding of the fireworks cylinder is completed, under the action of the feeding assembly 1, it moves to the film sealing mechanism for film sealing, thereby completing the film sealing of the fireworks cylinder.

[0034] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
