Patent name: Method and device for facilitating the adjustment of preform pitches Patent applicant Quan Guan (Fujian) Machinery Industry Co., Ltd. Principal applicant Address 351117 Inventor of Shiting Development Zone, Jiangkou Town, Putian City, Fujian Province Application No. 200410048680.0 Application date 2004.06. 04 Approval date Approval Notice No. 1695926 Date of approval announcement 2005.11.16 Specification CD No. D0546 Main classification number B29C49/42 Classification No. B29C49/42 Classification Original application No. Priority item 2004.5.12 CN 200420027155.6 Abstract The present invention discloses an easy adjustment The method for preparing the preform spacing comprises preparing a track extending along a closed curve and arranging in advance on the track a plurality of vehicle groups abutting each other. Each vehicle group includes a first carrier and at least a second carrier. The carrier is used for pivoting a bottleneck and providing a bottle of embryos thereon; removing a plurality of vehicle groups from the track; and using a number of second carriers of the same number as the group of vehicles remaining on the track; Each second carrier is respectively placed in each corresponding carrier group; by changing the number of each second carrier, the distance between each of the preform seats is simply changed. In the device of the present invention, the first carrier has a first contact area at the front end and a second contact area at the rear end. The first and second contact areas have the same radius of curvature; the second carrier has a third contact area at the front end. And a fourth contact area of ​​the rear end, the third and fourth contact areas have the same radius of curvature as the first and second contact areas. The present invention also has the advantage of reducing the wear between them. Sovereignty item 1. A method for facilitating the adjustment of the spacing between preforms, characterized by comprising at least the following steps: a. preparing a track extending a predetermined length along a closed curve, and arranging a plurality of carriers abutting one another on the track in advance Each group includes a first carrier and at least a second carrier, wherein the first carrier is used to pivot a bottle preform, and a preform is set thereon; b. Take out some vehicle groups from the track; c. take the same number of second carriers as the number of vehicle groups remaining on the track; d. place each of the second carriers in step c. In each corresponding group of vehicles, the distance between each preform station can be increased by changing the number of each second carrier in each vehicle group.
