Problems solved by technology

The existing plastic preform heater still has the following defects: the first is that the adjustment of the heating lamp tube adopts the whole (several lamp tubes) to adjust at the same time, which cannot adapt to the different requirements of the plastic preform section for the heating lamp tube; The circular transmission chain of the plastic preform runs at a uniform speed. The heated plastic preforms come out of the heating zone one by one, and the mold of the stretch blowing machine generally processes two or more plastic containers at the same time, such as For products such as mineral

Embodiment Construction

[0007] The invention discloses a plastic bottle preform heater for producing plastic hollow containers. There is a frame 12 of the heater, and the frame 12 is mainly installed to drive the plastic preform to run (including the circular revolution of the plastic preform, such as figure 1 , image 3 Shown, and rotation, rotation is the same as the transmission mechanism of prior art), and the heating device etc. that plastic bottle blank is heated are formed. The heating device is the heating lamp tube 11 located on both sides of the workbench 29 of the frame. When assembling, the two ends of the heating lamp tube 11 are connected with the adjusting rod 9 to form a U shape. The adjusting rod 9 is movably assembled with the bracket, and the bracket is installed on the frame 12. On the workbench 29, the reflection plate 20 corresponding to the heating lamp tube 11 is installed in the middle of the workbench 29. Through the following more specific structure, the bracket for instal...

Abstract

The plastic bottle blank heater is one hollow plastic container producing apparatus. The plastic bottle blank heater consists of one transmission mechanism to drive plastic bottle to run and one heating unit on the frame. The heating unit includes heating lamp tubes on two sides of the bench, regulating rods on two ends of the heating lamp tubes, support matching the regulating rods and on the bench, and reflecting boards corresponding to the heating lamp tubes and installed in the middle of the bench. Owing to the movable mounting of the regulating rods on the support, each of the heating lamp tubes may be regulated in position based on the requirement of heated plastic bottle blank to form reasonable heating environment, and this raises the heating quality of plastic bottle blank and the quality of the plastic bottle product.

Description

technical field [0001] The invention relates to processing equipment for plastic containers, in particular to heaters for plastic bottle preforms. Background technique [0002] PET and other polyesters are used as raw materials to produce plastic packaging containers such as beverage bottles, oil bottles, medicine bottles and cosmetic bottles. forming. The quality of preform heating directly affects the qualification rate of plastic container molding products, so the composition of plastic preform heaters is the key equipment for two-step processing of plastic hollow containers. The existing plastic preform heater still has the following defects: the first is that the adjustment of the heating lamp tube adopts the whole (several lamp tubes) to adjust at the same time, which cannot adapt to the different requirements of the plastic preform section for the heating lamp tube; The circular transmission chain of the plastic preform runs at a uniform spee...
