Description

Technical Field

[0001] The utility model relates to plastic product forming equipment, in particular to a supporting and adjusting device for a sheet feeding chain track. Background Art

[0002] In the plastic product manufacturing and molding equipment, the sheet feeding chain rail cooperates to transport the material output from the continuous sheet (i.e., continuous sheet) to each station for corresponding production, such as the heating station, the molding station, etc. The sheet feeding chain rail usually includes a left rail structure and a right rail structure, which are installed on the frame and supported by the frame. Due to the change in the left and right width specifications of the sheet, it is necessary to adjust the left and right spacing between the left and right rail structures. The weight of the left and right rail structures and the weight of the continuous sheet transported are heavy. If it is directly connected to the frame mounting plate by a screw rod, its structure is unstable, and the screw rod is easily bent and deformed under force, which affects the support and left and right adjustment of the sheet feeding chain rail, and its operation stability is relatively poor. In addition, the sheet will sag after being heated (heated at the heating station). If the sagging of the sheet is not discovered and handled in time, it will affect the normal operation and use of other devices. Utility Model Content
