Method and equipment for producing cup of beaker

Abstract

This invention provides method and apparatus for producing beaker. The method comprises: (1) cutting glass tube into 2.1-2.3 times of the height of beaker body, placing the cut glass tube on the transmission tray at the front end of the frame, moving by the channel on the transmission tray to the nozzle of the flaring device, heating both ends of the glass tube and flaring; (2) heating the middlepart of the flared glass tube, pressing the middle part into bottle neck shape by a neck-pressing mold, cooling, heating the middle part again, and separating at the middle neck part by the force toward the two ends from the bottom pressure foot to obtain the bodies of two beakers; (3) pre-sealing the bottoms by the nozzle, sealing the bottoms, finishing, polishing, annealing, and outputting by aconveyer belt. The method has such advantages as high production efficiency, high product quality, and low raw material consumption.

Description

Technical field [0001] The invention relates to a production method and a device for a beaker body. Background technique [0002] At present, the production method of the beaker body generally adopts artificial blowing to make a blank, and then artificially bakes and bakes the mouth. This method has the following defects: First, the product quality is low. The wall thickness of the cup body is uneven, and after the cup body blank is baked, a fuse node will be left on the cup mouth, which will affect the appearance and quality of the beaker; the second is low productivity, because it is artificially blown, and the labor intensity of workers High, especially the production of small-sized beaker cups shows the problem of low shift output and low output value; third, the consumption of materials in the production process is large, and the excess part after the beaker blank is baked is waste, but occupies the cup body. More than one-third of the dead weight increases the product...

[0002] At present, the production method of the beaker body generally adopts artificial blowing to make a blank, and then artificially bakes and bakes the mouth. This method has the following defects: First, the product quality is low. The wall thickness of the cup body is uneven, and after the cup body blank is baked, a fusing node will be left on the cup mouth, which will affect the appearance and quality of the beaker; the second is low productivity, because it is artificially blown, and the labor intensity of workers High, especially the production of small-sized beaker cups shows the problem of low shift output and low output value; third, the consumption of materials in the production process is large, and the excess part after the beaker blank is baked is waste, but occupies the cup body. More than one-third of its own weight, which increases production costs

Yet existing glass tube is owing to adopt the method for free fall to make, and the outward appearance of glass tube is smooth and clean, and wall thickness is uniform, but beaker has bottom, so the production method of beaker cup can not adopt free fall
