Problems solved by technology

Due to the difference in proficiency in manual operation, the heating time of the preform is different, and the thermal stability of the blown plastic bottle is quite different, which affects the filling performance of the product.
In recent years, domestic manufacturers have also developed automatic bottle blowing machines. Although the problem of thermal stability differences in plastic bottles has been solved to a certain extent, the bottle blowing process and equipment are still one-time medium-temperature blow molding crystallization, that is, after The heated preform is directly blown into shape by a set of medium temperature molds
The inherent molecular structure of the blown plastic bottle is unstable, resulting in a low heat-resistant temperature of the product, and there are differences in thermal stability. When the product is used in hot-filled beverages such as tea and fruit juice Low, poor thermal stability, easy to deform and scrap, reduce production efficiency and increase production cost

Embodiment Construction

[0016] The bottle blowing machine includes a rack 1, a feeding device 4 connected to each other, a ring conveying track 13 and a heating device 7 and a bottle stripping mechanism 14 are installed on the rack 1 and the ring conveying track 13 is installed with front and back follower Two sets of inner chucks 3 for holding the preform are installed on the slide 2, and the inner chucks 3 can also be more than two sets. The preform is fed in by the feeding device 4, is clamped by the inner chuck 3, and moves circularly along the track 13. A chain 6 meshing with the inner chuck 3 is arranged between the two inner chucks 3 in the heating device 7. The chain 6 rotates and cooperates with the motor 17 through the sprocket at both ends, so that the preform continuously rotates when it advances and ensures that it is evenly heated. On the rear part of the heating device 7 on the frame 1, a medium temperature mold 8, a high temperature mold 9, a secondary heating device 10, and a medium temp...

Abstract

A full-automatic blow mouding technology for making the refractory plastic bottles includes such steps as feeding bottle blank, heating, medium-temp blowing, high-temp blowing and meduim-temp blowing. Its blowing machine is composed of machine frame, feeder, endless conveying track, heater, medium-temp mould, high-temp mould, medium-temp shaping mould, and bottle releasing mechanism.

Description

Technical field [0001] The invention belongs to the technical field of plastic bottle manufacturing technology and its equipment, and is specifically a heat-resistant bottle full-automatic bottle blowing technology and a bottle blowing machine for realizing the technology. Background technique [0002] At present, the well-known hollow plastic bottle blowing process and its corresponding blowing equipment mostly use a two-step method, that is, the plastic bottle preform is injection molded first, and then the plastic bottle is blown molded by heating to the blowing temperature. In the bottle blowing process and its corresponding equipment, the preform feeding, heating, mold clamping, blow molding, unloading and other processes are connected by manual operation. Due to the difference in the proficiency of the manual operation, the heating time of the preform varies, and the thermal stability of the blown plastic bottle varies greatly, which affects the fi...
