Description

Technical Field

[0001] The invention mainly relates to the technical field of fireworks and firecracker charging devices, and in particular to a fireworks effect inner tube charging tray. Background Art

[0002] In the automated production line for charging inner tubes of fireworks effects, there are several workstations including one with a function for vibrating the medicine. The inner tube cakes need to be moved to different workstations on a pallet to perform the corresponding processes.

[0003] In order to allow the opened medicine to penetrate into other medicines, the inner cylinder cake filled with medicines needs to be vibrated. During the process of vibrating the medicines, the inner cylinder cake must be connected to the vibration mechanism to transmit the vibration force to the medicines, and after the vibration is completed, the inner cylinder cake must be able to return to the tray to move to the next station. This means that the tray must not only have the ability to cooperate with the external conveying mechanism to transport the inner cylinder cake to each station, but also have the ability to adapt to the station where the medicines are vibrated.

[0004] In the prior art, the tray can only support and transport the inner cylinder cake, but cannot be adapted to the vibrating medicine station, thus hindering the automation of the equipment. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a firework effect inner tube powder loading tray.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: A fireworks effect inner tube powder loading tray comprises a lower tray, one end of which is provided with a roller matched with an external track, and the other end of which is connected to an external conveying mechanism. The lower tray can be moved among various stations in sequence under the drive of the external conveying mechanism. An upper tray is detachably covered on the top of the lower tray, and a plurality of first clearance holes penetrating in the vertical direction are formed on the lower tray for an external lifting device to vertically pass through and lift the upper tray away from the lower tray.

[0007] One end of the lower tray is provided with a roller that cooperates with the external track, and the other end is connected to the external transmission mechanism. Under the drive of the external transmission mechanism, the end connected thereto starts to move, thereby driving the roller at the other end to slide along the external track. By controlling the moving distance of the external transmission mechanism, the position of the lower tray in the transmission mechanism is regulated, that is, the tray is driven to move in sequence between each station by the external transmission mechanism. The upper tray is detachably covered on the lower tray, and the lower tray is provided with a plurality of first clearance holes, which can be passed through by the external lifting device. The lifting device can lift the upper tray away from the lower tray and push it to the bottom of the vibration mechanism, so that the external inner cylinder cake on it can contact the vibration mechanism to complete the vibration of the medicine in the inner cylinder cake. After the vibration is completed, the lifting device returns to its position, driving the upper tray on it to be re-set on the lower tray, and the external transmission mechanism drives the lower tray to drive the upper tray to move to the next station. This fireworks effect inner cylinder charging tray has strong adaptability to the entire fireworks effect inner cylinder charging automatic production line, accurate positioning, and high degree of automation. In addition, in the prior art, since the firework effect inner cylinder charge tray is connected to the external frame, the external frame will interfere with the vibration effect during vibration, making it difficult to achieve the desired effect. However, the present application sets a movable upper tray, which is separated from the lower tray and the external frame during vibration. Without the interference of the external frame, the vibration of the inner cylinder cake is more sufficient, thereby improving the vibration effect.

[0008] In the above-mentioned fireworks effect inner tube charge tray, preferably, the number of the first clearance holes is not less than two, and they are evenly distributed along the circumference of the vertical center line of the upper tray.

[0009] The number of the first clearance holes is not less than two, and they are evenly distributed along the circumference of the vertical center line of the upper tray. That is, the first clearance holes are evenly distributed along the vertical axis passing through the center point of the upper tray. This arrangement can ensure that the entire upper tray is evenly stressed, so that it is steadily pushed to the bottom of the vibration mechanism by the lifting device, and provides good supporting force for the upper tray and the inner cylinder cake during the vibration process, preventing the upper tray from tilting during the vibration process, thereby affecting the vibration effect.

[0010] In the above-mentioned fireworks effect inner cylinder charge tray, preferably, at least three baffles are protruding from the top surface of the upper tray to limit the lateral movement of the outer inner cylinder cake, and the baffles are evenly distributed along the circumference of the outer inner cylinder cake.

[0011] The top surface of the upper tray is provided with at least three baffles for limiting the lateral movement of the outer inner cylinder cake. On the one hand, it prevents the outer inner cylinder cake on it from sliding on the upper tray due to inertia force when the upper tray moves to different workstations, thereby affecting the operation accuracy of each process; on the other hand, when the vibration mechanism vibrates, the baffles can prevent the outer inner cylinder cake from falling or deviating from the upper tray due to the vibration force, thereby resulting in unsatisfactory drug vibration effect.

[0012] In the above-mentioned fireworks effect inner cylinder charge tray, preferably, the blocking piece is bent toward one side of the outer inner cylinder cake to form an elastic pressing piece, and the elastic pressing piece laterally presses the side wall of the outer inner cylinder cake.

[0013] The baffle is bent toward one side of the outer inner cylinder cake to form an elastic pressing sheet, and it can laterally squeeze the side wall of the outer inner cylinder cake so that the outer inner cylinder cake and the baffle can fit tightly, thereby enhancing the blocking effect of the baffle and preventing the outer inner cylinder cake from being laterally displaced due to inertia or vibration force, ensuring that it can fully fit with the mechanism of each process and avoiding a series of loading problems caused by position deviation of the outer inner cylinder cake.

[0014] In the above-mentioned firework effect inner tube charge tray, preferably, a plurality of sockets for connecting to an external lifting device are formed on the bottom of the upper tray.

[0015] The setting of the socket can connect the lifting device to the upper tray, and then push the upper tray to the bottom of the vibration mechanism, so that the outer inner cylinder cake supported on it can complete the vibration of the medicine. After the vibration is completed, the lifting device is reset, and the upper tray connected to it is re-installed on the lower tray. In the vibration process, the lifting device can serve as a pillar to provide support for the upper tray.

[0016] In the above-mentioned fireworks effect inner cylinder charge tray, preferably, the fireworks effect inner cylinder charge tray also includes a middle tray arranged between the lower tray and the upper tray, and the middle tray is formed with a plurality of second clearance holes that pass through vertically, and the second clearance holes correspond to the first clearance holes one by one; and the middle tray protrudes vertically downward to form a top column, and the top column passes through the third clearance hole formed in the lower tray.

[0017] The middle tray is provided with a plurality of second vertically penetrating holes, and their positions correspond to the positions of the first clearance holes, so that the lifting device can pass through the lower tray and the middle tray in sequence and connect with the jack of the upper tray during the vibration process, ensuring that the lifting device can push the upper tray to the bottom of the vibration device. The middle tray is provided with a top column, which passes through the third clearance hole of the lower tray, so that the lifting mechanism can push the middle tray, and then the inner cylinder cake supported on the upper tray is close to the charging mold for charging.

[0018] In the above-mentioned fireworks effect inner tube charge tray, preferably, the middle tray also vertically protrudes downward to form a plurality of guide columns, and the guide columns can be slidably inserted in the guide tube arranged on the lower tray.

[0019] The guide column is provided to connect the lower tray and the middle tray on the one hand, and to position the middle tray after it is lifted.

[0020] In the above-mentioned fireworks effect inner tube charge tray, preferably, the depth of the guide column inserted into the guide tube is greater than the lifting stroke of the middle tray.

[0021] The depth of the guide post inserted into the guide cylinder is greater than the lifting stroke of the middle tray, which can prevent the middle tray from completely separating from the lower tray and ensure that the middle tray can be smoothly reset after being lifted.

[0022] In the above-mentioned firework effect inner tube charge tray, preferably, a plurality of bosses are provided at the bottom of the upper tray, and the bosses correspond one-to-one to the second clearance holes.

[0023] A number of bosses are provided at the bottom of the upper tray, and the second clearance holes on the tray correspond one to one. On the one hand, the upper tray and the middle tray can be fitted together through the bosses, thereby increasing the integrity of the tray structure; on the other hand, the socket of the upper tray for connecting to an external lifting device is arranged in the middle of the boss, and its position corresponds one to one with the second clearance holes of the middle tray, thereby facilitating the positioning of the lifting device.

[0024] In the above-mentioned firework effect inner tube charge tray, preferably, the boss is configured as a trapezoidal structure with a contracted lower end, and the maximum diameter of the boss is consistent with the aperture of the second clearance hole.

[0025] The boss is configured as a trapezoidal structure with a contracted lower end, which is beneficial for the boss at the bottom of the upper tray to slide smoothly into the second clearance hole under the action of its own weight. The boss is aligned with the aperture of the second clearance hole at its maximum diameter, which can play a good fixing role and prevent the upper tray from shaking in the second clearance hole of the middle tray, thereby increasing the reliability of the entire tray structure.

[0026] Compared with the prior art, the advantages of the present invention are: The firework effect inner tube charge tray of the present invention can flexibly adjust the relative height of the upper tray and the lower tray according to the requirements of the vibration station or other stations, and can be moved to other stations driven by an external conveying device. The charge tray has strong adaptability to various processes, precise positioning, and a high degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS
