Problems solved by technology

[0005] The purpose of the present invention is to overcome the above-mentioned defects and provide an externally supported preform detection and fixing device. By setting a positioning component, a pressure component and a conduction component, the support mechanism supports the process of moving down the preform, and the pressure component compresses the air. The conduction component guides the compressed gas out so that the positioning component forms an oblique downward pressure on the inner wall of the preform to realize the fixation of the preform. In addition, by pushing the component, multiple pressing blocks of the positioning component work synchronously, thereby solving the problem of bottle The positioning is not accurate during the preform detection process, and the preform is prone to tilt during the positioning process, which affects the subsequent detection.

Embodiment 1

[0044] Such as Figure 1 to Figure 13 As shown, an externally supported preform detection and fixing device includes a turntable 1, a support mechanism 2 and a positioning mechanism 3 are arranged on the turntable 1, and the positioning mechanism 3 includes a positioning assembly 31 and is arranged inside the positioning assembly 31. A pressure assembly 32, a conduction assembly 33 is also provided between the positioning assembly 31 and the pressure assembly 32, and a pushing assembly 34 is provided between the conduction assembly 33 and the positioning assembly 31;

[0045] The support mechanism 2 supports the preform 10 to move downward so that the preform 10 is sleeved on the outer wall of the positioning assembly 31, and at the same time drives the pressure assembly 32 to compress the air, and then drives the conduction assembly 33 to move down to make the compression in the pressure assembly 32 The gas is transferred to the space below the pushing assembly 34 to drive th...

Embodiment 2

[0061] Such as Figure 5 with Figure 7 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between the second embodiment and the first embodiment is that: at least two sliding grooves 3111 on the side wall of the positioning column 311 are arranged in an array along the circumferential direction of the positioning column 311 .

[0062] Furthermore, the end of the pressing block 3112 is set as a curved surface, and the radius of the curved surface is the same as the radius of the inner wall of the preform 10, and the end of the pressing block 3112 is provided with a flexible layer on the curved surface.

[0063] In this embodiment, a plurality of chutes and briquetting blocks are arranged in a circular array so that the preform is evenly stres...

Abstract

The invention relates to an external support type preform detection and fixing device, comprising a turntable, a support mechanism and a positioning mechanism are arranged on the turntable, the positioning mechanism includes a positioning assembly and a pressure assembly arranged inside the positioning assembly, the positioning assembly There is also a conduction assembly between the conduction assembly and the positioning assembly, and a pushing assembly is provided between the conduction assembly and the positioning assembly; the support mechanism supports the bottle blank to move downward so that the bottle blank is sleeved on the outer wall of the positioning assembly, At the same time, drive the pressure component to compress the air, and then drive the conduction component to move down to transfer the compressed gas in the pressure component to the space below the push component, drive the push component to move up, and drive the positioning component to synchronize the inner wall of the preform in the circumferential direction Press down at an angle to secure. The invention solves the problem of inaccurate positioning during the detection process of the preform, and the tendency of the preform to tilt during the positioning process, which affects the subsequent detection.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to an externally supported preform detection and fixing device. Background technique [0002] The preform is an intermediate in the production of bottles. The quality of the plastic bottle needs to be tested during the production process. If the preform used to produce the bottle is defective, the bottle produced will also be defective. Therefore, the preform needs to be inspected. , Eliminate the defective ones and proceed to subsequent bottle production to avoid production waste. [0003] The Chinese utility model patent with the publication number CN205192965U discloses an embedded preform detection system, which connects the input turntable to the first detection turntable, and the first detection turntable to the second detection turntable to achieve high efficiency of the preform. Automated contactless inspection. [0004] But this equipment does not disclose how...
