PVC film heating device

Abstract

The invention discloses a PVC film heating device. The PVC film heating device comprises a mounting frame, wherein a lifting mechanism is mounted at the upper end of the mounting frame; supporting columns are mounted at the two ends of the mounting frame; sliding grooves are formed in the two supporting columns; a motor is fixedly connected to the back face of one supporting column through nuts; a first gear and a second gear arranged at the left end of the first gear are welded to the output end of the motor; a first heating drum is arranged at the left end of the second gear; a third gear is movably connected to the lower end of the first gear; a second heating drum matched with the first heating drum is arranged at the left end of the third gear; anti-adhesion devices are arranged on the first heating drum and the second heating drum; and the output end of the motor is sleeved with the lifting mechanism. According to the PVC film heating device, the heating drums internally provided with heating rods are adopted to replace heating plates, so that the working efficiency of the PVC film heating device is improved; and the anti-adhesion devices are arranged on the heating drums, so that the problem that a PVC film adheres to the heating drums due to the over high temperature is solved, and the rejection rate is reduced.

Description

Technical field[0001]The present invention relates to the field of thin film heating, and more particularly to a PVC film heating device.Background technique[0002]At present, the PVC film heating temperature control regulation of flat aluminum plastic blister packaging machine on the market is mainly to use the upper and lower two pieces of electric heating plates that are plated with a polytetrafluoroethylene coating, and the temperature control is carried out in a temperature controller. In order to prevent the temperature of the PVC film, the disadvantage of this control method is that the temperature is extremely difficult to control during operation, resulting in an increase in the PVC film, resulting in an increase in fluidity, thereby moving the process The medium is pasted onto the upper and lower heating plates, forming resistance, stretching the PVC film, so that the PVC film is narrowed or discriminated, which is quite high on the material material, otherwise the producti...

Problems solved by technology

[0002] At present, the method of controlling and adjusting the heating temperature of the PVC film of the flat aluminum-plastic blister packaging machine on the market is mainly to use the upper and lower two electric heating plates coated with Teflon coating, and cooperate with the temperature controller to control the temperature. , in case the temperature is too high and melts the PVC film, the disadvantage of this control method is that during the operation, due to the extremely difficult temperature control, the PVC film is easy to be overheated, resulting in an increase in fluidity, and thus in the process of walking Paste it on the upper and lower heating plates to form resistance, stretch the PVC film, and make the PVC film narrow or break. The material requirements are quite high, otherwise the waste of raw materials will be large, and the production cost and manufacturing cost will be high.

The number of shutdowns caused by temperature failure during the operation of the equipment is particularly frequent, and the scrap rate is as high as 20%, and the heating plate can only heat one film at a time, so the heating device has low working efficiency.
