A chain track device capable of automatically adjusting the width of the chain track

Abstract

A chain rail device capable of automatically adjusting the width of the chain rail, including a frame, two chain rails, a front end width adjustment assembly, a rear end width adjustment assembly, a middle width adjustment assembly, a controller and multiple encoders, the front end The width adjustment assembly, the rear end width adjustment assembly and the middle width adjustment assembly all include a drive motor, an adjustment screw and two translation seats. The adjustment screw has a left screw section and a right screw section with opposite helical directions. On the two chain rails, the translation seat on the left is provided with a left screw hole engaging with the left screw section, and the translation seat on the right is provided with a right screw hole engaging with the right screw section; The encoders are respectively installed on the corresponding adjusting screw rods, each encoder is respectively electrically connected to the corresponding input end of the controller, and each driving motor is respectively electrically connected to the corresponding output end of the controller. The chain rail device can automatically adjust the width of the two chain rails during the production process, and the adjustment is precise.

Description

technical field [0001] The invention relates to plastic molding equipment, in particular to a chain rail device capable of automatically adjusting the width of the chain rail. Background technique [0002] When the plastic molding equipment such as cup making machine and blister machine is working, the two ends of the plastic sheet are clamped on the chains in the two chain rails side by side before being conveyed, and the plastic sheet is separated by the chains in the two chain rails. The material is transported forward, heated and softened by the heating device, and then formed at the forming device. [0003] In order to solve the problem of parallelism of the two chain rails, the applicant applied for a Chinese invention patent with the application number CN201720831807.9 on July 11, 2017, which discloses a chain rail with automatic width adjustment, including two horizontal The chain rail arranged in parallel with the direction is characterized in that: it also include...

AI Technical Summary

Problems solved by technology

However, when the plastic sheet is heated by the heating device, the plastic sheet will expand due to heat and its own gravity, and its middle part will often sag, causing the sheet to be uneven and uneven in thickness when it is fed into the molding device, thus affecting the quality of the plastic sheet.
