Description

Technical Field

[0001] This utility model relates to the field of fireworks tube production technology, specifically to a plywood secondary flipping device. Background Technology

[0002] In the production process of fireworks inner tubes, there is a crucial step of flipping the inner tube assembly plate with the lead wire. This step involves the first flipping operation of the fireworks inner tube, adjusting it from its original orientation to a tail-up position. This tail-up orientation serves subsequent processes, primarily to facilitate the filling of the tail end of the fireworks inner tube by operators or automated equipment, ensuring that the filler is accurately placed in the designated position at the tail end. After the tail filling process is completed, the fireworks inner tube needs to be readjusted from its tail-up orientation to a tail-down orientation (fitting against the bottom of the tooling plate) for easier subsequent transfer or assembly. This requires a second flipping operation to restore the orientation. The assembly plate secondary flipping device involved in this application is designed to complete the aforementioned second flipping action.

[0003] However, during the process of resetting the plywood by flipping it over, the material filled at the tail of the fireworks' inner tube in the previous process will spill out during the flipping process, which not only wastes materials but also pollutes the working environment. Utility Model Content

[0004] The purpose of this invention is to provide a plywood secondary flipping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plywood secondary flipping device, including a frame and a clearance opening. Bearing seats are fixedly installed at both ends of the frame, and a secondary flipping bracket is rotatably installed inside the bearing seats at both ends. A belt drive component is sleeved on the driven pulley of the coaxial side end of the secondary flipping bracket, and the end of the belt drive component facing away from the secondary flipping bracket is sleeved on the drive pulley of the rotating end of the flipping motor. The flipping motor is fixedly installed on the side end of the frame. A collection hopper is provided at the bottom end of the frame, and a lifting cylinder is fixedly installed at the top end of the frame. A pressing plate is fixedly connected to the telescopic end of the lifting cylinder, and the needle-shaped protrusion at the bottom end of the pressing plate is inserted into the interior of the flipped-up plywood body firework tube through the clearance opening.

[0006] Furthermore, the secondary flipping bracket has clearance openings at both the upper and lower ends, and a partition is horizontally fixed in the middle of the secondary flipping bracket.

[0007] Furthermore, the secondary flipping bracket is equipped with conveyor belts on both sides inside, and the conveyor belts are symmetrically distributed at the upper and lower ends of the partition.

[0008] Furthermore, the plywood body is supported on the conveyor belt located on the same side, and the drive part of the conveyor belt is fixedly connected to the rotating end of the conveyor motor, and the conveyor motor is fixed to the outside of the secondary tilting bracket.

[0009] Furthermore, positioning cylinders are symmetrically fixed at both ends of the secondary flipping bracket, and the telescopic ends of the positioning cylinders are pressed against the partition plate body to fix it. A limit cylinder is fixed on one side of the secondary flipping bracket, and a contact limit switch is connected to the telescopic end of the limit cylinder.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model is applied to the transfer of the inner tube of fireworks between two tooling plates. In the previous process, the tail end of the inner tube of fireworks faces upward, which is convenient for the processing of the tail filling. After the tail filling is processed, in the second flipping process of this application, it needs to be flipped again so that the tail end of the inner tube of fireworks is turned back to the bottom of the tooling plate. During this process, the material filled at the tail end of the fireworks tube will spill. This application adds a collection hopper under the frame to recover the excess pyrotechnic material, avoids the waste of pyrotechnic material, improves the safety of subsequent process production, reduces production costs, and also maintains the cleanliness of the working environment.

The flipping motor 5 is fixedly installed on the side end of the frame 1. A collection hopper 13 is provided at the bottom end of the frame 1, and a lifting cylinder 14 is fixedly installed at the top end of the frame 1. A pressing plate 15 is fixedly connected to the telescopic end of the lifting cylinder 14, and the needle-shaped protrusion at the bottom end of the pressing plate 15 is inserted into the firework tube of the plywood body 9 facing upward through the clearance opening 6. The specific operation is as follows: This application is applied to the transfer of the inner tube of fireworks between two tooling plates.
