Description

Technical Field

[0001] This utility model relates to the field of plastic fuel tank processing technology, and in particular to a plastic fuel tank burr removal device. Background Technology

[0002] Plastic fuel tanks are formed by blow molding a preform within the cavities of the left and right halves of a mold. After molding, the fuel tank has excess material around the parting line, forming flash. This flash needs to be removed using a trimming tool mechanism. Existing flash cutting technology has the following drawbacks: 1. The traditional method involves manually holding the plastic fuel tank and aligning the flash with the trimming tool for cutting. This is slow, inefficient, requires high skill, and easily damages the tank's edges. 2. The newly molded plastic fuel tank is very hot, making manual handling inconvenient for trimming.

[0003] Currently, existing technology (CN220661499U) discloses a plastic fuel tank burr removal device, including a base, a controller, a cutting mechanism, and a rotating mechanism. The cutting mechanism includes a cutter, a position adjustment component, an angle adjustment component, and a lifting component. The rotating mechanism includes a drive component and two pressure plates. One pressure plate is rotatably mounted on the top of the base via a first rotating shaft. A support rod is fixedly mounted on the top of the base, and a second rotating shaft is mounted on the top of the support rod. A mounting plate is fixedly mounted on the bottom of the second rotating shaft, and a push cylinder is fixedly mounted on the mounting plate. The other pressure plate is fixedly mounted on its output end, and the axes of the two pressure plates are aligned. The position adjustment component, angle adjustment component, lifting component, and drive component are all electrically connected to the controller, eliminating the need for manual cutting, thus improving cutting speed and saving labor costs.

[0004] Using the above method, when cutting plastic fuel tanks, debris is easily scattered, which not only pollutes the environment but may also injure workers. At the same time, cleaning up the debris is also more troublesome, increasing production costs and safety risks. Utility Model Content

[0005] The purpose of this invention is to provide a plastic fuel tank burr removal device, which aims to solve the problem of debris flying easily when cutting plastic fuel tanks.

[0006] To achieve the above objectives, this utility model provides a plastic fuel tank burr removal device, including a base, a removal mechanism, and a protective mechanism. The protective mechanism includes a drive assembly, a threaded rod, a threaded cylinder, a movable frame, and a protective cover. The removal mechanism is mounted on the base, the drive assembly is mounted inside the base, the threaded rod is rotatably connected to the base and fixedly connected to the drive assembly, the threaded cylinder is threadedly connected to the threaded rod and located around the threaded rod, the movable frame is fixedly connected to the threaded cylinder and located around the threaded cylinder, and the protective cover is mounted on the movable frame.

[0007] The drive assembly includes a drive motor, a worm gear, and a worm wheel. The drive motor is fixedly connected to the base and located inside the base. The worm gear is fixedly connected to the output end of the drive motor and rotatably connected to the base. The worm wheel meshes with the worm gear and is rotatably connected to the base.

[0008] The protection mechanism further includes multiple guide rods and multiple sliding cylinders. The multiple guide rods are fixedly connected to the base and are all located inside the base. The multiple sliding cylinders are slidably connected to the multiple guide rods and are fixedly connected to the movable frame.

[0009] The protective cover includes a shell and two closed plates. The shell is fixedly connected to the movable frame and is located on the movable frame. The two closed plates are rotatably connected to the shell and are both located on the shell.

[0010] The protective mechanism includes two observation plates, which are fixedly connected to the cover and located on one side of the cover.

[0011] This utility model discloses a plastic fuel tank flash trimming device. The base provides installation conditions for the trimming mechanism and the protective mechanism. The trimming mechanism can trim the flash of the plastic fuel tank. When trimming the plastic fuel tank, the drive assembly is activated, which drives the threaded rod to rotate. The threaded rod drives the threaded cylinder to move away from the drive assembly. The threaded cylinder drives the moving frame to move away from the base. The moving frame drives the protective cover to move away from the base until the protective cover is raised to a preset height. The protective cover closes the trimming mechanism, preventing debris from flying during the trimming mechanism's operation, thus solving the problem of debris flying easily when cutting plastic fuel tanks.
