Description

Technical Field

[0001] This utility model relates to the technical field of ton drum blow molding machines, specifically a high-efficiency and energy-saving ton drum blow molding machine. Background Technology

[0002] A tonne container (TBM) is a large container used for storing and transporting liquids. A TBM blow molding machine is a specialized piece of equipment for producing TBMs. It uses hollow blow molding technology, heating and melting plastic raw materials. The molten plastic is then extruded through a die to form a tubular preform. After the preform enters the mold, the mold closes, and the preform adheres to the inner wall of the mold, where it cools and solidifies to form a hollow container.

[0003] After the mold is closed, there is a shearing device between the mold and the mold head to hold the parison. When demolding, the mold opens and separates from the parison. The shearing device clamps the parison and cuts it, causing the parison to separate from the plastic on the mold head. Then, the shearing device moves the parison to be discharged from the mold position.

[0004] Following the above process, the next round of blow molding begins. In this next round, after mold closing, the shearing device needs to reset before clamping and shearing. This reset process has a long stroke and time. Furthermore, during the shearing process, there is a risk that the parison cut by the shearing device may detach from the device, making it impossible to ensure stable output of the parison with the shearing device. With the increasing demand for cost reduction and efficiency improvement in the ton-of-container (TOC) industry, increasing the speed of TOC blow molding machines has become one of the core goals of technological development. Therefore, to address the above issues, we have further optimized the design of the TOC blow molding machine, resulting in a highly efficient and energy-saving TOC blow molding machine. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency and energy-saving blow molding machine for ton drums, which solves the problems of traditional blow molding machines that require waiting for the shearing device to reset before clamping and shearing when entering the next round of production, and the shearing device's inability to ensure stable output of the parison, thus affecting production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency and energy-saving blow molding machine for ton drums, comprising a mold body mounted on a sliding track, wherein the left and right molds of the mold body slide and move on the sliding track to close and open the mold, a receiving platform is provided at the bottom of the mold body, and a horizontal belt conveyor is provided at the bottom of the mold body perpendicular to the guiding direction of the sliding track, the horizontal belt conveyor being located between the left and right molds of the mold body, the horizontal belt conveyor being mounted by a lifting drive device, the lifting end of the lifting drive device being fixed on the frame of the horizontal belt conveyor, and the conveyor belt of the horizontal belt conveyor being distributed on both sides of the receiving platform;

[0007] The top of both the left and right molds of the mold body is provided with a linear guide rail parallel to the sliding track. The left mold of the mold body is slidably equipped with a clamping frame one via the linear guide rail.

The right mold of the mold body is slidably equipped with a clamping frame two via the linear guide rail. The clamping frame two is fixedly connected to the output end of the translation drive cylinder two. The opposing surfaces of the clamping frame one and the clamping frame two are clamping surfaces. The top of the clamping frame one is provided with a cutting device. The cutting device includes an electric cylinder and a cutting tool. The electric cylinder is arranged along the direction perpendicular to the linear guide rail. The cutting tool is arranged along the direction parallel to the linear guide rail. The cutting tool is fixed to the extension end of the electric cylinder. The cutting tool has cutting edges on both the front and rear sides. The cutting tool is driven by the electric cylinder to reciprocate at the clamping surface position on the top of the mold body.

[0008] Preferably, the lifting drive devices are distributed at both ends of the horizontal belt conveyor, and the horizontal belt conveyor is set across the sliding track via the lifting drive devices.

[0009] Preferably, the lifting drive device includes a fixed frame, a movable frame, a guide assembly, and a lifting drive cylinder. The lifting drive cylinder is fixed between the fixed frame and the movable frame. The movable frame is located above the fixed frame and is driven to lift by the lifting drive cylinder. The guide assembly is disposed between the fixed frame and the movable frame. The movable frame is fixed on the frame of the horizontal belt conveyor.

[0010] Preferably, the guiding component is a guide rod and guide sleeve assembly, and the lifting drive cylinder is distributed between the two sets of guide rod and guide sleeve assemblies.

Compared with the traditional shearing device, which requires reset before clamping and shearing, this method saves cycle time and improves work efficiency. Furthermore, the horizontal belt conveyor supports the parison for stable discharge, avoiding the problem of the parison falling off the shearing device and affecting production efficiency in the traditional operation method.
