Description

Technical Field

[0001] This utility model relates to fireworks manufacturing equipment, and in particular to an automatic inner cylinder cake conveyor used in conjunction with a fireworks inner cylinder filling machine. Background Technology

[0002] Currently, most large-scale fireworks production involves manually loosening the clamps on hexagonal inner tube cakes in the feed frame or on the conveyor belt, then piling the inner tubes (paper tubes containing effect powder and fuses) into the hopper of the inner tube filling machine. The inner tubes are then mechanically inserted into the launch holes of the molded outer tube of the fireworks to complete the filling process. This work structure requires operators to always be present near the inner tube filling machine. Due to the large distance between the manual feeding operation and the inner tube filling machine (operators generally need to work within 1 meter to fill the inner tube into the hopper), the limited working area cannot separate personnel from the machine. Within this working area, the inner tubes are subject to vibration, compression, collision, and friction, posing a safety hazard. Therefore, this inner tube filling method poses a safety risk of injury to operators during production and does not comply with national regulations requiring the safe separation of personnel and machinery in fireworks production. Utility Model Content

[0003] In view of the problems existing in the operation of the inner tube filling machine in the prior art, this utility model provides an automatic conveyor for the inner tube of fireworks that not only has high inner tube filling efficiency and can reduce operating costs, but also eliminates the need for operators to operate in dangerous areas, achieves safe separation of man and machine, and ensures the safety of operators.

[0004] The technical solution adopted by this utility model to solve the technical problem is: an automatic conveyor for separating the man-machine interface of fireworks inner tubes. It is installed on one side of an inner tube filling machine arranged in parallel and used in conjunction with the inner tube filling machine. The inner tube filling machine is equipped with a flipping mechanism that can change the inner tube cake conveyed by the conveyor from a horizontal to a vertical position. The automatic conveyor for separating the man-machine interface of fireworks inner tubes includes several parallel conveyor chains that can rotate intermittently. Several trays are fixedly arranged at intervals on the conveyor chains, and several layers of inner tube cakes can be placed on the trays. An X-axis seat body is fixedly arranged above the output end of the conveyor chains, spanning the parallel conveyor chains. A support frame that moves in the Y direction is movably arranged in the middle of the X-axis seat body, and an X-axis rack is movably arranged on the X-axis seat body. A servo motor I is fixedly mounted on the support frame. An X-axis gear connected to the output shaft of servo motor I meshes with an X-axis rack. A servo motor II is fixedly mounted on the support frame. A Y-axis moving plate is movably mounted on the support frame. A Y-axis rack is fixedly mounted on the Y-axis moving plate. A Y-axis gear connected to the output shaft of servo motor II meshes with the Y-axis rack. A lifting mechanism is provided at one end of the Y-axis moving plate. The lifting mechanism includes a lifting cylinder. Two relatively movable clamping plates in the shape of a semi-regular hexagon are fixedly mounted at the lower end of the piston rod III of the lifting cylinder. The clamping plates are connected to clamping cylinders fixed on the top plate through guide plates. An auxiliary cylinder is fixedly mounted on the top plate. A clamp is provided at the lower end of the piston rod II of the auxiliary cylinder. A clamping cylinder is provided on the clamp.

[0005] The working process of this utility model is as follows: Several layers of inner cylinder cakes are manually placed outside the isolation wall in each pallet fixed on the conveyor chain of the conveyor. The drive motor 27 is started to drive the conveyor chain 11 to move from left to right along the Y-axis direction through the active sprocket and the driven sprocket. When the pallet moves to a suitable position on the right end of the conveyor (the specific suitable position is controlled by the displacement sensor), according to the signal of which of the multiple parallel inner cylinder filling machines needs to be filled with inner cylinder, the servo motor I is started to drive the support frame to move in the X-axis direction. At the same time, the servo motor II drives the Y-axis moving plate on the support frame to move in the Y-axis direction on the support frame. When the lifting cylinder 17 fixed on one end of the Y-axis moving plate moves to the position of the flipping body 1-1 of the inner cylinder filling machine, the Y-axis moving plate stops moving. At this time, the lifting cylinder on the lifting mechanism descends (moves downward along the Z-axis direction). Through the piston rod III 16 mounted on the lifting cylinder Two opposing, semi-hexagonal clamping plates at the lower end close under the action of clamping cylinder 38 to clamp the inner cylinder cake on the tray. After clamping, the support frame moves in the X-axis direction and the Y-axis moving plate on the support frame moves simultaneously, placing the inner cylinder cake on the horizontal flipping body 1-1. The flipping body rotates 90 degrees to make the horizontal inner cylinder cake vertical. Then, the top cylinder 1-2 and the ejection cylinder 1-3 press the inner cylinder cake into the cake clamping frame in the filling machine. The cake clamping frame is released, and the inner cylinder is added into the storage hopper to complete the filling. At the same time, the auxiliary cylinder 40 fixed on the top plate works. The clamp 41 on the descending piston rod II 43, under the action of clamping cylinder 42, clamps the clamping clamp in the clamping plate and sends it to the appropriate position. The clamp is released, and the clamp is placed in the designated appropriate position. Afterwards, the clamping cylinder operates, and piston rod II 16 rises and returns to its original position. Then, as needed, a signal is added to the inner cylinder, activating servo motor I to drive the support frame to move in the X-axis direction. At the same time, servo motor II drives the Y-axis moving plate on the support frame to move in the same Y-axis direction on the support frame. The two opposing clamping plates at the lower end of piston rod III 16 of the lifting cylinder, which are half-hexagonal in shape, close under the action of the clamping cylinder to clamp the inner cylinder cake on the tray. After clamping, the inner cylinder cake is placed on the horizontal flipping body 1-1 by moving the support frame in the X-axis direction, the Y-axis moving plate on the support frame moving in the Y-axis direction, and the piston rod III 16 descending in three directions. This cycle continuously feeds the inner cylinder into the storage hopper on the inner cylinder filling machine, ensuring balanced and continuous production of the inner cylinder filling machine.

[0006] The beneficial effects of this utility model are: the inner cylinder filling machine has high inner cylinder filling efficiency, can reduce operators, can reduce operating costs, and operators do not need to operate in the dangerous area inside the isolation wall, but operate in the safe area outside the isolation wall at a distance of not less than 2 meters from the inner cylinder filling machine. The inner cylinder filling production can achieve separation of man and machine, ensuring the personal safety of operators. Attached Figure Description
