Abstract
The invention relates to a full-automatic sheet putting and feeding mechanism. According to the full-automatic sheet putting and feeding mechanism, sheets required to be unreeled and fed are placed on an unreeling device to be conveyed to a clamping and conveying mechanism, and under the effect of traction tensile force of equipment in the front, the sheets are guided by a guide roller and clamped by a plastic roller and a metal roller of the clamping and conveying mechanism to be conveyed forwards. In the conveying process, due to the fact that the sheets are clamped by the plastic roller and the metal roller, biased errors are accumulated step by step along with time; and an opening and closing driving device mounted on a rack drives an upper seat body to rotate around a rotating shaft by a certain angle, the upper seat body and a lower seat body are separated, the plastic roller and the metal roller are separated, and the plastic roller and the metal roller lose clamping force on the sheets, so that the sheets which gradually deviate are automatically corrected under the effect of the traction tensile force of the equipment in the front, the correct conveying direction is recovered, error accumulation generated by gradual deviation is removed, the sheet conveying yield is ensured, and it is ensured that the follow-up process can be smoothly carried out.
Description
Technical field
The present invention relates to a kind of feed mechanism, particularly relate to a kind of full-automatic film releasing feed mechanism.
Background technology
Existing thermoforming machine is generally matingly provided with feed mechanism, mainly plays a part raw material supply and auxiliary pan feeding.When sheet material volume is placed on feed mechanism, feed mechanism is by, after sheet material is rolled up expansions, tensioning, set level, then being transported to follow-up processing unit (plant), and therefore, direct and thermoforming machine the production efficiency of sheet efficiency of sending of film advance mechanism has important relation.
But, existing feed mechanism generally comprises unwinding device and pinch roll, pinch roll is generally made up of a metallic roll and a plastic cement roller, plastic cement roller is in above metallic roll, metallic roll therein is often set to drive roll, plastic cement roller and metallic roll are clamped sheet material and are fed forward, in course of conveying, effect due under tension, sheet material is susceptible to deviation, and owing to sheet material is always clamped by plastic cement roller and metallic roll, the error of this sheet material deviation can be accumulated further, in the course of time, sheet material deviation is increasingly severe, even twist into twisted shape, the qualification rate of serious product, and the progress of subsequent handling.
Summary of the invention
Problem to be solved by this invention is to provide a kind of full-automatic film releasing feed mechanism, this full-automatic film releasing feed mechanism can automatically correct sheet material in unreeling process, sheet material is avoided to occur deviation to reverse in course of conveying, it is ensured that the qualification rate of product, and the running smooth of subsequent handling.The technical scheme adopted is as follows:
A kind of full-automatic film releasing feed mechanism, including frame, unwinding device, guide roller, pinch mechanism and a plurality of storing roller, unwinding device, guide roller, pinch mechanism, storing roller are successively set in frame, it is characterised in that: described pinch mechanism includes pinching driving device, lower base, upper pedestal, metallic roll, plastic cement roller and folding driving mechanism；Pinching driving device and lower base is installed in described frame, metallic roll may be rotatably mounted on lower base, and the clutch end pinching driving device is in transmission connection with metallic roll；One side of upper pedestal may be rotatably mounted on lower base by rotating shaft, and folding driving mechanism is arranged in frame, and the clutch end of folding driving mechanism is connected with the opposite side of upper pedestal.
