A preform defect online detection equipment

Abstract

The present invention provides an on-line detection device for preform defects, comprising a bracket, a photographing detection device, a preform conveying device, an interval separation device and an auxiliary detection device. The photo detection space, the photo detection device is located in the photo detection space; the detection auxiliary device includes a rotary drive assembly, a preform limit assembly and a limit drive assembly; The transferred preforms are arranged at intervals in the further transmission process, and the preforms that have been sorted are clamped in a rotary motion with the aid of the detection device and then transferred to the photo-detection space for photo-detection. At the same time, during the clamping process The photographing aids are inserted into the preform to realize the reflective shielding during the detection of the preform, which solves the technical problem that the photographic detection device passes through the transparent preform and the detection effect is poor.

Description

technical field [0001] The invention relates to the field of preform manufacturing and production, in particular to an online detection device for preform defects. Background technique [0002] At present, plastic bottles have been widely used in food, beverage, medicine, daily chemical products and other industries. With the continuous growth of demand, the consumption of plastic bottles continues to increase. In order to meet the demand, automatic assembly lines are now used to manufacture plastic bottles. After the preforms of plastic bottles are molded from the injection molding machine, they need to pass the appearance inspection before entering the bottle blowing process, so as to prevent the preforms with damaged bottle necks, bottle shoulders or bottle body scratches from entering the blow molding machine and causing the blow molding machine to stop , affecting production line productivity. [0003] In the prior art, when the number of preforms in the entrance slide...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an on-line detection device for preform defects. By setting up a separation device and a detection auxiliary device respectively, the preforms linearly transmitted by the separation device can be arranged at intervals during the further transmission process. , and cooperate with the detection auxiliary device to clamp the sorted preforms in a rotary motion and transfer them to the photo inspection space for photo inspection. At the same time, the photo auxiliary parts are inserted into the preforms during the clamping process to realize the The reflective occlusion during the photo inspection process solves the low efficiency and high cost of the preform inspection process, and at the same time solves the technical problem that the photo inspection device penetrates through the transparent preform and the detection effect is poor
