Heating plate mounting and moving mechanism

Abstract

The invention discloses a heating plate mounting and moving mechanism. The heating plate mounting and moving mechanism comprises a hot plate moving frame, a heating plate and a forward-moving driving assembly, wherein an ear part is arranged on the heating plate, a hot plate positioning seat, a hot plate rear lock assembly and a side edge locking assembly are arranged on the hot plate moving frame, and the hot plate positioning seat, the hot plate rear lock assembly and the side edge locking assembly are matched with the ear part of the heating plate; the hot plate rear lock assembly comprises a rear lock cylinder and a rear lock push block, and the side edge locking assembly comprises a side air cylinder and a side pressure rod; a heating socket is further arranged on the heating plate, and a heating plug is further arranged on the hot plate moving frame. According to the heating plate mounting and moving mechanism, the heating plate positioning seat, the heat plate rear lock assembly and the side edge locking assembly are used for matching and locking the ear part of the heating plate; when the heating plate works to enable the ear part to be expanded with heat, the ear part can generate slight deformation toward the outer side, the machining precision of the hot plate and the hot plate rear lock assembly and the side edge locking assembly cannot be influenced, the heating plate can be unlocked without waiting for cooling of the heating plate, the heating plate can be removed and replaced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of hot plate welding machines, in particular to a heating plate installation and moving mechanism for hot plate welding machines. Background technique [0002] The hot plate welding machine is used for welding various accessories. The hot plate welding machine uses the principle of electric heating to weld with the mechanical transmission structure, which can make up for the shortcomings of the ultrasonic welding machine in welding large and special plastic workpieces. The hot plate welding machine is more It is suitable for welding thermoplastic materials such as PP and PE, as well as plastic workpieces with large and complex welding joints; while the existing hot plate welding machine, the installation and fixing structure of the heating plate cannot meet the needs of automatic replacement and overcoming thermal expansion at the same time. It will affect the processing accuracy and service life of the heat...
