Plastic bottle pipe heater locating friction-conveying chain

Abstract

The present invention relates to a device for positioning, frictionating and transmitting chain of plastic bottle-tube heater. The device is arranged on a friction bracket and a chain bracket on the heater; a friction tape is arranged on the friction bracket; a drive chain is arranged on the chain bracket; the plastic bottles are transmitted between the friction tape and the chain; the invention is characterized in than a rotary position friction pulley is arranged on the chain; the rotary position friction pulley is inserted between the plastic bottle-tubes and contacted with heads of the plastic bottle-tubes. According to the technical proposal, the rotary position friction pulley is arranged on the chain (can be one side); the rotary position friction pulley extends (is inserted) between each plastic bottle-tube in operation (the plastic bottle-tubes import into the heater one by one in discontinuous arrangement); the plastic bottle-tube is positioned to maintain a certain spacing distance in heating operation; friction on the bottle-tube can generate rotation while the bottle-tube moves forward (revolution); the device is good in heating effect and conducive for entering a subsequent stretch and blow processing.

Description

technical field [0001] The invention relates to a plastic bottle tube heater, in particular to a positioning friction conveying chain for a plastic bottle tube heater, and belongs to the field of plastic machinery. Background technique [0002] In the production of hollow plastic containers, such as processing mineral water bottles, oil bottles, cosmetic bottles, etc., the plastic raw materials are first injected into bottle tubes by injection molding machines, and then the plastic bottle tubes are heated by a heater, and then heated by a stretch blowing machine. Bottle tube stretch blow molding. The vast majority of existing plastic bottle tube heaters insert the bottle tube on the support base, and the support base is driven by a chain or slider to heat the bottle tube through the heating zone. The disadvantage of this technology is not only the machine structure It is complicated, and more importantly, if it is combined with a stretch-blow machine, there are many sets of...

AI Technical Summary

Problems solved by technology

However, in practice, due to the flat friction between the friction belt or the friction chain and the bottle mouth, the speed of each bottle tube will be uneven during the forward operation, resulting in inconsistent lengths and short distances between the bottle tubes. Affect the heating effect of the bottle tube, and bring difficulties to the process of entering the stretch blowing machine
