Description

Technical Field

[0001] This utility model mainly relates to the field of fireworks and firecracker manufacturing machinery technology, and in particular to a mechanism for dispensing powder into the inner tube of fireworks effects. Background Technology

[0002] In automated production lines for filling inner cylinders with propellant for fireworks effects, after the inner cylinder cakes are filled with gunpowder, they need to be stacked and transported to the shipping station. Current technology uses only a single conveyor belt, which has at least the following drawbacks:

[0003] First, since there is only one conveyor belt, both stacking loose inner tube cakes into piles and transporting piled inner tube cakes to the shipping station rely solely on this one conveyor belt. Therefore, when stacking loose inner tube cakes into piles, the conveyor belt must be stationary, making it impossible to transport already stacked inner tube cakes. Conversely, when transporting already stacked inner tube cakes, the conveyor belt is in motion, preventing stacking operations. In other words, with only one conveyor belt, interference inevitably occurs between the two processes of stacking loose inner tube cakes into piles and transporting piled inner tube cakes to the shipping station, thus affecting overall production efficiency.

[0004] Secondly, the filling of the inner tubes for fireworks effects is a continuous process. To avoid the accumulation of loose inner tube cakes, the stacking speed needs to be accelerated, which means the conveyor belt must frequently stop. Since the same conveyor belt is used to transport stacked inner tube cakes to the shipping station, frequent stops will reduce the transport speed. This results in situations where stacked inner tube cakes have not yet been sent to the shipping station, but loose inner tube cakes have already been placed on the conveyor belt. As a result, the conveyor belt will carry several stacks of inner tube cakes at the same time. Since inner tube cakes filled with gunpowder have a risk of combustion and explosion, large-scale accumulation will greatly increase the risk factor and make it difficult to meet the safety production requirement that the safe distance between adjacent stacks of inner tube cakes should be greater than 1 meter. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mechanism for dispensing medicine into the inner tube for fireworks effects.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A mechanism for dispensing powder into an inner tube for fireworks effects includes a first conveyor belt and a second conveyor belt, with the output end of the first conveyor belt connected to the input end of the second conveyor belt; it also includes a robotic arm mechanism for placing the outer inner tube powder onto the first conveyor belt.

[0008] The fireworks effect inner tube loading mechanism of this application uses a robotic arm to place the outer inner tube cakes onto a first conveyor belt. The output section of the first conveyor belt is connected to the input section of a second conveyor belt, facilitating the transport of the stacked outer inner tube cakes placed by the robotic arm to a second conveyor. By employing the cooperation of the first and second conveyor belts, the two processes of stacking scattered inner tube cakes into piles and transporting the piled inner tube cakes to the shipping station are controlled separately. This solves the problem of difficulty in coordinating and controlling the stacking of inner tube cakes when using only a single conveyor belt for static stacking and transport, thus improving the loading efficiency and safety of the inner tube cakes.

[0009] In the above-mentioned fireworks effect inner cylinder medicine feeding cake mechanism, preferably, the first conveyor belt includes a first support, at least a pair of first rollers are arranged at intervals along the transmission direction on the first support, a first belt for carrying the outer inner cylinder cake is fitted on the first roller, and at least one of the first rollers is connected to the first drive mechanism.

[0010] The first bracket provides support for the installation of the first roller, ensuring that the first belt fitted onto the first roller remains taut. The three components form a stable annular conveyor belt, with at least one first roller connected to the first drive mechanism. This means that at least one active first roller drives the other driven first rollers to rotate, thus moving the annular conveyor belt. The first drive mechanism can be existing conventional equipment, such as a motor. The motor's output shaft is connected to the first roller, allowing the first roller to rotate under the motor's drive, thereby moving the entire first conveyor belt.

[0011] In the above-mentioned fireworks effect inner cylinder loading mechanism, preferably, the second conveyor belt includes a second support, at least a pair of second rollers are spaced apart along the transmission direction on the second support, a second belt for carrying the outer inner cylinder cake stack is fitted on the second roller, and at least one of the second rollers is connected to the second drive mechanism.

[0012] The second bracket provides support for the installation of the second roller, ensuring that the second belt fitted onto the second roller remains taut. The three components form a stable annular conveyor belt, with at least one second roller connected to the second drive mechanism. This means that at least one active second roller drives the other driven second rollers to rotate, thus moving the annular conveyor belt. The second drive mechanism can be existing conventional equipment, such as a motor. The motor's output shaft is connected to the second roller, causing it to rotate and thus moving the entire second conveyor belt.

[0013] In the above-mentioned fireworks effect inner cylinder loading mechanism, preferably, the second support is also equipped with a number of rollers at intervals along the transmission direction for supporting the outer inner cylinder cake stack, and the rollers are located inside the second belt.

[0014] The idlers supporting the outer inner cylinder cake stack are installed at intervals on the inner side of the second belt, that is, the idlers are located in the middle of the upper and lower second belts of the ring transmission structure, to provide support for the second belt, prevent the second belt from sinking due to the weight of the outer inner cylinder cake stack, and avoid the failure of the conveying function of the second conveyor belt.

[0015] In the above-mentioned fireworks effect inner tube medicine feeding mechanism, preferably, the fireworks effect inner tube medicine feeding mechanism further includes a support for fixing the first conveyor belt and the second conveyor belt, and the bottom end of the support legs of the support is provided with a support foot with height adjustment function.

[0016] The first and second conveyor belts are mounted on the support, and the bottom of the support legs are equipped with height-adjustable feet. The height of the support can be adjusted appropriately according to the stacking height of the outer inner cylinder cake grasped by the robotic arm mechanism, so that the first and second conveyor belts are at a reasonable height, ensuring that the outer inner cylinder cake grasped by the robotic arm mechanism can be accurately and efficiently stacked on the first conveyor belt.

[0017] In the above-mentioned mechanism for dispensing medicine into the inner tube for fireworks effects, preferably, the robotic arm mechanism includes a main support, a secondary support that is slidably mounted on the main support along the horizontal direction, and a robotic claw that is slidably mounted on the secondary support along the vertical direction.

[0018] A secondary support is slidably mounted on the main support along its horizontal axis, and a mechanical gripper is slidably mounted on the secondary support along its vertical axis. The secondary support can slide horizontally along the main support, driving the mechanical gripper on it to move horizontally. The mechanical gripper itself can also slide along the secondary support. In other words, through the cooperation of the main support and the secondary support, the mechanical gripper can be controlled to move up and down and back and forth, thereby enabling the mechanical gripper to accurately grasp and transport the outer inner cylinder cake to the first conveying mechanism.

[0019] In the above-mentioned fireworks effect inner tube medicine feeding mechanism, preferably, the main support includes a crossbeam, a plurality of guide rods are provided on the crossbeam, a transverse slider is fitted on the guide rod, and the transverse slider is connected to a telescopic cylinder fixed on the crossbeam.

[0020] The transverse slider is mounted on the guide rod and is connected to the telescopic cylinder fixed on the crossbeam. The telescopic cylinder can drive the transverse slider connected to it to slide along the guide rod, thereby causing the auxiliary support connected to it to move back and forth along the direction of the guide rod.

[0021] In the above-mentioned fireworks effect inner tube medicine feeding mechanism, preferably, the auxiliary support includes a vertical frame connected to the main support, the vertical frame is provided with a vertical guide rail, a vertical slider is slidably installed on the vertical guide rail, the vertical slider is threadedly connected to a lead screw passing through it, and one end of the lead screw is connected to a motor fixed on the vertical frame.

[0022] The vertical slider is mounted on the vertical guide rail and is connected to the motor via a lead screw. The motor can drive the lead screw to move vertically, which in turn drives the vertical slider connected to the lead screw to slide along the vertical guide rail, and further drives the robot arm connected to the vertical slider to move up and down.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] The fireworks effect inner tube charging mechanism of this application adopts the cooperation of a first conveyor belt and a second conveyor belt to separate and control the two processes of stacking scattered inner tube cakes into a stack and transporting the stacked inner tube cakes to the shipping station. This solves the problem of difficulty in coordinating the static stacking and inner tube cake stacking when using only one conveyor belt, and improves the charging efficiency and safety of the inner tube cakes.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example

[0030] like Figure 1 and Figure 2 As shown, the fireworks effect inner tube medicine loading mechanism of this embodiment includes a first conveyor belt 1 and a second conveyor belt 2, with the output end of the first conveyor belt 1 connected to the input end of the second conveyor belt 2; it also includes a robotic arm mechanism 3 for placing the outer inner tube medicine 01 onto the first conveyor belt 1.

[0031] In this embodiment, the first conveyor belt 1 includes a first support 11, on which at least a pair of first rollers 12 are spaced apart along the conveying direction. A first belt 13 for carrying the outer inner cylinder cake 01 is fitted on the first rollers 12, and at least one of the first rollers 12 is connected to a first drive mechanism 14. The first drive mechanism can be an existing conventional device, such as a motor.

[0032] In this embodiment, the second conveyor belt 2 includes a second support 21, on which at least a pair of second rollers 22 are spaced apart along the conveying direction. A second belt 23 for carrying the outer inner cylinder stack 02 is fitted onto each second roller 22, and at least one of the second rollers 22 is connected to a second drive mechanism 24. The second drive mechanism can be any existing conventional equipment, such as a motor.

[0033] In this embodiment, a number of rollers 25 for supporting the outer inner cylinder cake stack 02 are also installed at intervals along the transmission direction on the second support 21. The rollers 25 are located inside the second belt 23.

[0034] In this embodiment, the inner tube of the firework effect for loading the medicine cake also includes a support 4 for fixing the first conveyor belt 1 and the second conveyor belt 2. The bottom of the support legs 41 of the support 4 is provided with a foot 42 with height adjustment function.

[0035] In this embodiment, the robotic arm mechanism 3 includes a main support 31, a secondary support 32 is slidably mounted on the main support 31 along the horizontal direction, and a robotic claw 33 is slidably mounted on the secondary support 32 along the vertical direction.

[0036] In this embodiment, the main support 31 includes a crossbeam 311, a plurality of guide rods 312 are provided on the crossbeam 311, and a transverse slider 313 is fitted on the guide rods 312. The transverse slider 313 is connected to a telescopic cylinder 314 fixed on the crossbeam 311.

[0037] In this embodiment, the auxiliary support 32 includes a stand 321 connected to the main support 31. The stand 321 is provided with a vertical guide rail 322. A vertical slider 323 is slidably installed on the vertical guide rail 322. The vertical slider 323 is threadedly connected to a lead screw 324 passing through it. One end of the lead screw 324 is connected to a motor 325 fixed on the stand 321.

[0038] In this embodiment, when the cake is being unloaded, the first conveyor belt remains stationary, the motor 325 starts, and drives the vertical slider 323, which is indirectly connected to the conveyor belt, to slide downwards along the vertical guide rail 322 until the mechanical claw 33 connected to it grabs the outer inner cylinder cake 01. The mechanical claw 33 tightens, and the motor 325 is controlled to drive the slider indirectly connected to it to slide upwards along the vertical rail for a certain distance before stopping (the bottom elevation of the mechanical claw 33 should be slightly greater than the height of the first conveyor belt 1 or the upper surface of the outer inner cylinder cake 01 on the conveyor belt). The telescopic cylinder 314 is then activated to drive the horizontal slider 313 to move forward. The mechanical claw 33 moves until it is directly above the first conveyor belt 1. Then, the motor 325 is started again to control the vertical slider 323 to slide down until the mechanical claw 33 contacts the first conveyor belt 1 or the upper surface of the outer inner cylinder cake 01 on the first conveyor belt 1. The mechanical claw 33 releases the outer inner cylinder cake 01 and controls the mechanical claw 33 to reset. The above operation is repeated until the outer inner cylinder cake 01 is stacked into a pile. The first conveyor belt 1 is started to transfer the outer inner cylinder cake pile 02 on it to the second conveyor belt 2. The second conveyor belt 2 then transfers the outer inner cylinder cake pile 02 on it to the shipping station.
