Embodiment Construction

[0019] Please refer to Fig. 1 to Fig. 5 at the same time, the circulation structure of the stretch-blow molding machine disclosed by the present invention mainly consists of a conveyer belt 10 which can circulate along a predetermined conveying path and more than one bottles arranged on the conveyer belt 10 Composed of 30 germ seats.

[0020] The conveyor belt 10 is formed by pivoting two or more adjacent first chain links 20 and second chain links 20'.

[0021] Each first chain link 20 has: a bridging portion 22 having a certain length, and its long axis direction is perpendicular to the extending direction of the conveying path; a pair of connecting portions 24 are slightly T-shaped, and are respectively protruding from the bridging portion 22 The two ends of each bridging portion 22 ( 22 ′) and the connecting portion 24 ( 24 ′) jointly enclose an accommodating space 40 .

[0022] The shape of each second chain link 20' is almost the same as that of the first chain link 20,...

Abstract

The invention provides a circulation structure for a stretch-blow molding machine, comprising a conveyer belt which cycles along a preset route. The conveyer belt consists of two or more chain links which are pivoted one by one in order and a chain link comprises a bridging part with preset length, whose prolate axis is perpendicular to the circulation direction, a pair of connecting parts convexly arranged parallel on the preset places of the bridging part respectively with a preset distance; the connecting parts have preset length and the front ends and the rear ends of the connecting parts are respectively pivoted with the rear ends and the front ends of the adjacent chain links through the same bolt; a accommodation room is confined among the bridging part, a pair of connecting parts and a pair of bolts. A bracket is arranged inside the accommodation room to hold the conveyer belt which has certain length and weight.

Description

【Technical field】 [0001] The present invention is to provide a conveying device of a stretch-blow molding machine, in particular to a circulation structure of a stretch-blow molding machine for conveying preforms. 【Background technique】 [0002] In the technical field of stretch-blow molding machines, traditional stretch-blow molding machines, such as those disclosed in U.S. Patent No. 4,328,760, Chinese Patent No. 9322666.0, and Taiwan Publication No. 378178, are composed of one or more conveyor belts Circulating along a predetermined path, the conveyor belt is provided with a number of chain links, and the preform holders for carrying the preforms are set at the positions separated by appropriate chain links, and each preform passes through a heating device and a puller in turn. The blow molding unit works. [0003] The above-mentioned conveyor belt structure is similar to the chains used in general bicycles or transmission mechanisms. Each chain link that constitutes the...
