Description

Technical Field

[0001] The utility model relates to the technical field of fireworks production equipment, in particular to a fireworks tube batch integration device. Background Art

[0002] The fireworks tube is the container for releasing fireworks. Before filling it with gunpowder, special cardboard needs to be rolled into a tube shape, and a winding machine is used to cut the long tube to obtain the appropriate length of the fireworks tube.

[0003] According to the publication (announcement) number: CN213201560U, the publication (announcement) date: 2021-05-14, a fireworks tube batch integration device is disclosed.

[0004] In the prior art including the above-mentioned patent, a funnel-shaped hole is used to vertically arrange randomly scattered firework tubes, which are then placed on a conveyor belt for transportation through a vertical pipe. Although the purpose of keeping the firework tubes in a vertical position for transportation is achieved, when the firework tubes fall into the funnel-shaped hole, the two ends of the firework tubes are very likely to hit the side walls of the hole, causing the ends of the firework tubes to be concave and wrinkled, affecting subsequent processing. In severe cases, creases will appear on the side walls of the middle part of the firework tube, which will affect the falling of the firework tube and increase the scrap rate. Utility Model Content

[0005] The purpose of this utility model is to provide a device for batch integration of firework tubes, aiming to solve the above-mentioned problems.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A device for batch integration of fireworks tubes includes a guide tube with a central opening, wherein the guide tube further includes a funnel opening and a vertical opening arranged equidistantly in communication, and an upper buffer frame hingedly connected to the end of the funnel opening, wherein the upper buffer frame has a first curved path provided on its end surface, and the ends of the first curved paths on two upper buffer frames face each other to form a notch, and the notch is arranged coaxially with the vertical opening;

[0008] A first arc piece is slidably provided at the end of the first arc track, and a concave edge is provided at the end of the first arc piece.

[0009] Preferably, a lower buffer frame is hingedly provided in the funnel mouth, a second arc path is provided on the lower buffer frame, and a second arc piece that cooperates with the first arc piece is movably provided on the lower buffer frame.

[0010] Preferably, a push rod for pushing the lower buffer frame to move toward each other is fixedly mounted on the upper buffer frame.

[0011] Preferably, a touch rod is fixedly mounted on the lower buffer frame, and an elastic sheet that is pushed and slid by the push rod is fixedly mounted on the end of the touch rod.

[0012] Preferably, the push rod slides off the elastic sheet and causes the lower buffer frame and the upper buffer frame to move synchronously.

[0013] In the above technical solution, the utility model provides a batch integration device for fireworks tubes, which has the following beneficial effects: when a single fireworks tube falls into the funnel mouth through the central mouth, the fireworks tube slides into the first arc track first, and slides along the first arc track to the notch, and the gravity generated by the fireworks tube prompts the upper buffer frame to tilt rapidly toward the notch, until the fireworks tube that continues to fall downward gradually becomes vertical, and when the upper buffer frame in the opposite position is not under force and remains horizontal, the two first arc pieces can form a limiting support for the upper and lower staggered side walls of the fireworks tube, during which the ends of the fireworks tube are directly hit, and at the same time, the concave edge of the end of the first arc piece is used to adapt to the support position of the side wall of the fireworks tube, ensuring that the fireworks tube is accurately clamped and slides down, and then the spring on the first arc piece is used for buffering, which effectively reduces the damage to the side wall of the fireworks tube caused by the extrusion force, ensures the integrity of the fireworks tube, and reduces the scrap rate of fireworks tube production.

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, a device for batch integration of fireworks tubes includes a guide tube 1 with a central opening 11, and a funnel opening 12 and a vertical opening 13 are evenly spaced and connected in the guide tube 1. The device also includes an upper buffer frame 2 hingedly connected to the end of the funnel opening 12. The upper buffer frame 2 has a first curved channel 21 on its end surface. The ends of the first curved channels 21 on the two upper buffer frames 2 face each other to form a notch, and the notch is coaxially arranged with the vertical opening 13.

[0023] A first arc piece 23 is slidably provided at the end of the first arc track 21 , and a concave edge 231 is formed at the end of the first arc piece 23 .

[0024] Specifically, a torsion spring is provided at the hinged position of the upper buffer frame 2 (the torsion spring and its installation method are both existing technologies and will not be described in detail here). The deformation coefficient of the torsion spring is smaller than the gravity generated by a single firework tube, so that the upper buffer frame 2 can respond quickly to the force, and when multiple firework tubes are placed on the end face of the upper buffer frame 2, the gap is still enough for a single firework tube to pass through.

[0025] Furthermore, the first arc channel 21 is a downward depression on the end surface of the upper buffer frame 2, so that the fireworks tube can find the correct sliding position when it is lowered. The end of the first arc channel 21 is provided with a housing 22 for accommodating the retraction of the first arc piece 23, and the first arc piece 23 is also fixedly mounted with a spring fixedly connected to the inner wall of the housing 22. At the same time, a rubber pad is also fixedly mounted on the inner wall of the housing 22 to provide the damping required for buffering.

[0026] When a single firework tube falls into the funnel mouth 12 through the central opening 11, the firework tube will first slide into the first arc track 21 and slide along the first arc track 21 to the gap. The gravity generated by the firework tube will prompt the upper slow frame 2 to tilt rapidly toward the gap until the firework tube that continues to fall downward gradually becomes vertical. When the upper slow frame 2 in the opposite position is not under force and remains horizontal, the two first arc pieces 23 can form a limit support for the upper and lower staggered side walls of the firework tube. During this period, the ends of the firework tube are directly impacted, and at the same time, the concave edge 231 at the end of the first arc piece 23 is used to adapt to the supporting position of the side wall of the firework tube to ensure that the firework tube is accurately clamped and slides down. The spring on the first arc piece 23 is then used for buffering, which effectively reduces the damage to the side wall of the firework tube caused by the extrusion force, ensures the integrity of the firework tube, and reduces the scrap rate of firework tube production.

[0027] As an embodiment further provided by the present invention, a lower buffer frame 3 is hingedly provided in the funnel mouth 12 , a second arc path 31 is provided on the lower buffer frame 3 , and a second arc piece 32 that cooperates with the first arc piece 23 is movably provided on the lower buffer frame 3 .

[0028] Specifically, the length of the lower buffer frame 3 is smaller than that of the upper buffer frame 2 , so that the lower buffer frame 3 can stably deflect and move below the funnel opening 12 .

[0029] Furthermore, the second arc 31 has the same specifications as the first arc 21 so as to correct the fireworks tube below, and the second arc piece 32 is also provided with equidistantly arranged springs for buffering.

[0030] By setting up the lower slow frame 3, the vertically lowered firework tube can be supported for a second time, thereby increasing the support range of the firework tube in the funnel mouth 12 and preventing the firework tube from hitting the side wall of the funnel mouth 12. When the lowered firework tube is deflected, the second arc 31 can guide the firework tube until the firework tube is restored to vertical again. At the same time, the spring on the second arc piece 32 assists the firework tube to ensure the stability of the vertical lowering of the firework tube.

[0031] As another embodiment further provided by the present invention, a push rod 24 is fixedly mounted on the upper buffer frame 2 for pushing the lower buffer frame 3 to move toward each other.

[0032] Specifically, the push rod 24 is a hard metal rod and is installed below the upper buffer frame 2 .

[0033] The push rod 24 moves downward through the deflected upper buffer frame 2, and the push rod 24 pushes the lower buffer frame 3 to deflect upward. The purpose is that before the firework tube enters the gap, the second arc piece 32 on the lower buffer frame 3 is close to the gap in advance, so that the second arc piece 32 can receive the lowered firework tube, shortening the time of docking with the lower buffer frame 3 during the lowering process of the firework tube, and further reducing the problem of deflection of the firework tube.

[0034] As another embodiment further provided by the present invention, a touch rod 33 is fixedly mounted on the lower buffer frame 3 , and an elastic piece 34 that is pushed and slid by the push rod 24 is fixedly mounted on the end of the touch rod 33 .

[0035] Specifically, the elastic sheet 34 is a wear-resistant elastic metal sheet, and is in a barb shape with the touch rod 33 .

[0036] The push rod 24 moves downwardly and contacts the end of the elastic sheet 34. In the process of continuing to move downward, the elastic sheet 34 is deformed, so that the elastic sheet 34 pulls the contact rod 33 toward the side wall of the funnel mouth 12, that is, the lower slow frame 3 is pulled upward to deflect, making it easier for the lower slow frame 3 to carry out the receiving work.

[0037] As another embodiment further provided by the present invention, the push rod 24 slides off the elastic sheet 34 and causes the lower slow frame 3 and the upper slow frame 2 to move synchronously.

[0038] Specifically, a torsion spring is also provided at the hinged position of the lower buffer frame 3 , but the torsion spring does not work during the upward deflection of the lower buffer frame 3 .

[0039] The push rod 24 moves downward continuously until it slips off the elastic sheet 34. At this time, the lower buffer frame 3 loses the upward deflection force and deflects downward by itself, so that the lower buffer frame 3 can assist the upper buffer frame 2 in lowering the fireworks tube, increase the lowering stroke of the fireworks tube, and improve the stability of the fireworks tube before entering the vertical opening 13.

[0040] Working principle: When a single firework tube falls into the funnel mouth 12 through the central port 11, the firework tube slides into the first arc track 21 first, and slides along the first arc track 21 to the notch, and the gravity generated by the firework tube prompts the upper slow frame 2 to tilt rapidly toward the notch until the firework tube that continues to fall downward gradually becomes vertical. When the upper slow frame 2 in the opposite position is not under force and remains horizontal, the two first arc pieces 23 can form a limit support for the upper and lower staggered side walls of the firework tube, and at the same time cooperate with the concave edge 231 at the end of the first arc piece 23 to adapt to the support position of the side wall of the firework tube, ensuring that the firework tube is accurately clamped and slides down, and then cooperates with the spring on the first arc piece 23 for buffering, and the lower slow frame 3 can provide secondary support for the vertically lowered firework tube, thereby increasing the support range of the firework tube in the funnel mouth 12.

[0041] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
