Pressing-cutting ejection mechanism of thermoforming packaging machine

Abstract

The invention provides a pressing-cutting ejection mechanism of a thermoforming packaging machine, and belongs to the field of packaging machines. The pressing-cutting ejection mechanism comprises a pressing-cutting die frame and a fixed seat plate. A bearing seat plate can be slidably arranged between the pressing-cutting die frame and the fixed seat plate through a plurality of guiding columns.The bearing seat plate is provided with a cutter seat, and a cutter is fixed on the cutter seat. Communicating grooves are formed in the side walls of the left side and the right side of the cutter seat. Supporting strips are arranged in the grooves in an inserted mode, and the two ends, exposed out of the cutter seat, of each supporting strip are fixed on supporting strip seats correspondingly. The supporting strips in the cutter seat are provided with an ejection disc. Sliding rails are arranged on the left side wall and the right side wall of the fixed seat plate. Sliding blocks on the sliding rails are fixedly connected with the supporting strip seats. According to the pressing-cutting ejection mechanism of the thermoforming packaging machine, the ejection disc can be movably and internally arranged in the cutter seat, and the ejection disc ejects a small pack on the cutter seat in the process of downward moving of the bearing seat plate by using the vertical stroke of the bearingseat plate; and the pressing-cutting ejection mechanism can be applied to packaging of various sizes, and a guiding structure and a fixing structure of the supporting strips are arranged externally, so that the cutter seat or the ejection disc are convenient to replace.

Description

technical field [0001] The invention relates to the field of packaging machines, in particular to a press-cutting ejector mechanism of a thermoforming packaging machine. Background technique [0002] The existing package ejection structure, due to the setting of the cylinder joint below, if the package in the middle part of the tool holder is too small, it will overlap with the cylinder joint and the fixed position of the top plate cannot be set, so it is difficult to eject small packages or arrange special packages. Affects die cutting of parts of the package. Moreover, the structure of the existing packaging ejection mechanism is not easy to disassemble, and it will cause great inconvenience to replace the mold. [0003] Based on this, this application is filed. Contents of the invention [0004] The purpose of the present invention is to provide a press-cut package ejection mechanism applicable to thermoforming packaging machines of various sizes and shapes, which can...
