Technical Field
[0001] The utility model relates to the technical field of fireworks production equipment, and particularly relates to an anti-sticking device for fireworks tubes. Background Technique
[0002] The raw material for the production of fireworks tubes is roll paper, which becomes fireworks tubes after being processed by a fireworks tube manufacturing device. The fireworks tube manufacturing device generally includes an adhesive application component, a winding drum component, and a cutting component. During processing, glue is applied to the roll paper by the adhesive application component, then the roll paper coated with glue is wound into a drum by the winding drum component, and finally the drum is cut by the cutting component to cut it into drums meeting the length requirements, thus completing the production and manufacturing of fireworks tubes.
[0003] Since glue is applied to the roll paper during the production of fireworks tubes, there will be a situation where some glue overflows on the produced fireworks tubes. The fireworks tubes are easily stuck to each other due to the undried glue. Later, it is necessary to manually separate these stuck fireworks tubes, which results in a reduction in the production efficiency of fireworks, a high labor cost, and is prone to damage to the fireworks tubes, so that the fireworks tubes cannot be used normally, thus increasing the production cost.

Specific embodiments
[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Please refer to Figures 1-7 , a technical solution provided by an embodiment of the present invention: The anti-adhesion device for fireworks tubes includes a machine base 1. The top of the machine base 1 is rotatably connected with an incomplete gear 3 and a first gear 4 meshing with the incomplete gear 3. A plurality of positioning holes 10 for positioning the fireworks tube body 19 are arranged in a circumferential array on the first gear 4. The top end of the incomplete gear 3 is coaxially and fixedly connected with a first connecting rod 5. A spiral groove 6 with its head and tail connected is arranged on the first connecting rod 5. A slider 8 is reciprocally and vertically slidably connected to the first connecting rod 5. A protrusion 7 is arranged in the slider 8. The protrusion 7 can be slidably matched with any one of the spiral grooves 6. A collar 9 is fixedly connected to one side of the slider 8. A limiting member for restricting the circumferential rotation of the slider 8 is arranged on the machine base 1. A groove 22 is arranged on the machine base 1. The groove 22 can communicate with any one of the positioning holes 10. A driving member for driving the incomplete gear 3 to rotate is arranged in the machine base 1.
[0022] As a preferred technical solution, the driving member includes a motor 2. The output end of the motor 2 is coaxially and fixedly connected to the bottom end of the incomplete gear 3. The motor 2 drives the incomplete gear 3 to rotate, causing the first gear 4 to rotate intermittently, so that the fireworks tube body 19 clamped and positioned in the positioning hole 10 is located directly below the collar 9. At the same time, the incomplete gear 3 drives the rotating rod to rotate. Through the cooperation between the protrusion 7 and the spiral groove 6, the slider 8 drives the collar 9 to scrape the glue overflowing on the fireworks tube body 19. When the incomplete gear 3 rotates one week, the glue overflow scraping is completed. The first gear 4 rotates again, and the fireworks tube body 19 that has been scraped falls into the groove 22 and is collected. At the same time, the next fireworks tube body 19 to be scraped for glue overflow moves to directly below the collar 9. This device avoids the easy adhesion between fireworks tubes due to the undried glue, improves the production efficiency, and reduces the production cost.
[0023] As a preferred technical solution, the limiting member includes a guide rod 21. The guide rod 21 is vertically arranged at the top of the machine base 1. The slider 8 is vertically and slidably sleeved on the guide rod 21. Specifically, since the guide rod 21 is vertically arranged, the guide rod 21 restricts the circumferential rotation of the slider 8, so that the slider 8 can only drive the collar 9 to perform vertical reciprocating motion to scrape the glue overflowing on the fireworks tube body 19.
[0024] As a preferred technical solution, a second connecting rod 11 is coaxially and fixedly connected to the top of the first gear 4. A turntable 12 is coaxially and fixedly connected to the top of the second connecting rod 11. A plurality of tooth groups are distributed at intervals on the circumferential side of the turntable 12. A feeding cylinder 17 is vertically arranged on the machine base 1 through a bracket 18. A baffle 16 is rotatably connected to the bottom outlet of the feeding cylinder 17. A rotating shaft 14 is rotatably connected in the feeding cylinder 17. A torsion spring 15 is sleeved on the rotating shaft 14. The baffle 16 is sleeved on the rotating shaft 14. A second gear 13 is coaxially and fixedly connected to the bottom end of the rotating shaft 14. The second gear 13 can be meshed and connected with any one of the tooth groups. Specifically, the staff only needs to put the fireworks tube body 19 to be processed into the feeding cylinder 17. When the first gear 4 drives the turntable 12 to rotate, through the meshing transmission of one of the tooth groups and the second gear 13, the baffle 16 is driven to rotate at the same time. When one of the positioning holes 10 is directly below the feeding cylinder 17, the baffle 16 no longer blocks the outlet of the feeding cylinder 17, and the fireworks tube body 19 automatically falls into the corresponding positioning hole 10. When the turntable 12 rotates again and the tooth group is not meshed with the second gear 13, the baffle 16 is driven to rotate in the reverse direction through the elastic deformation of the torsion spring 15 to realize the blocking of the outlet of the feeding cylinder 17, which can avoid the problem of inaccurate manual feeding alignment and improve the feeding efficiency.
[0025] As a preferred technical solution, a guide rail 20 is arranged on one side of the machine base 1. The guide rail 20 communicates with the groove 22. The bottom wall of the groove 22 is inclined. Specifically, the fireworks tube body 19 from which the overflowing glue has been scraped falls into the groove 22 and slides into the guide rail 20 along the bottom wall of the groove 22, which is convenient for the next process operation.
[0026] Working principle: For the anti-adhesion device of the fireworks tube, the operator only needs to put the fireworks tube body 19 to be processed into the feeding cylinder 17. When the first gear 4 drives the turntable 12 to rotate, through the meshing transmission of one of the tooth groups and the second gear 13, the baffle 16 is driven to rotate at the same time. When one of the positioning holes 10 is directly below the feeding cylinder 17, the baffle 16 no longer blocks the outlet of the feeding cylinder 17, and the fireworks tube body 19 automatically falls into the corresponding positioning hole 10. When the turntable 12 rotates again and the tooth group does not mesh with the second gear 13, the elastic deformation of the torsion spring 15 drives the baffle 16 to rotate in the reverse direction to block the outlet of the feeding cylinder 17, which can avoid the problem of inaccurate manual feeding alignment, improve the feeding efficiency. The motor 2 drives the incomplete gear 3 to rotate, causing the first gear 4 to rotate intermittently, so that the fireworks tube body 19 clamped and positioned in the positioning hole 10 is directly below the collar 9. At the same time, the incomplete gear 3 drives the rotating rod to rotate. Through the cooperation between the protrusion 7 and the spiral groove 6, the slider 8 drives the collar 9 to scrape off the glue overflowing on the fireworks tube body 19. When the first gear 4 rotates again, the fireworks tube body 19 that has been scraped off falls into the groove 22 for collection. This device avoids the easy adhesion between fireworks tubes due to the undried glue, improves the production efficiency, and reduces the production cost.
[0027] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
