Automatic production line for plastic grafting clips

Abstract

An automatic production line for plastic grafting clips comprises a spiral extrusion machine, a cooling mechanism, a belt towing mechanism, a tension control mechanism, a belt feeding mechanism and a cropping mechanism, wherein the spiral extrusion machine, the cooling mechanism, the belt towing mechanism, the tension control mechanism, the belt feeding mechanism and the cropping mechanism are sequentially arranged; the tail end of the spiral extrusion machine is connected with a grafting clip mold, and the cooling mechanism comprises a cooling groove; the cooling groove is internally provided with a belt inlet guide wheel, a soaking belt guide wheel and a belt outlet guide wheel at least; the belt towing mechanism, the tension control mechanism, the belt feeding mechanism and the cropping mechanism are arranged on a supporting frame, and the tension control mechanism is arranged below the position between the belt towing mechanism and the belt feeding mechanism; and the tension control mechanism comprises a rotatable support movably hinged to the side face of the supporting frame, and a radial guide rod is arranged at the front end of the rotatable support. An extension spring fixed to the bottom of the supporting frame is further arranged on the rotatable support. The automatic production line is simple in structure, balance of belt walking tension of molding belts in all mechanisms is achieved, and the production efficiency and quality of the plastic grafting clips are improved.

Description

Technical field [0001] The invention relates to the technical field of agricultural grafting, and more specifically to an automatic production line of plastic grafting clips. Background technique [0002] Grafting is a relatively mature technology. There are many types of fixing parts used in grafting, some are wound with plastic film, and some are directly tied and fixed by rope. However, plastic grafting clamps are more commonly used at present, because of their simple structure, convenient use, low cost, and the grafting survival rate is relatively high. high. The plastic grafting clamp usually includes a left clamp handle, a right clamp handle and a clamping part with a clamping opening. The left clamp handle and the right clamp handle are symmetrically arranged on both sides of the clamping part. The right grip handle opens and closes the grip. [0003] At present, the production of plastic grafting clamps usually involves putting plastic rice into a screw extruder for heat...
