The invention relates to a diluting device, in particular to a VC (vitamin C) adhesive diluting device for production of PTP (polyterephthalate) aluminum foils for medicine package, which aims at solving the technical problem of providing a VC adhesive diluting device for production of PTP aluminum foils for medicine package with advantages of waste preventing, sufficient stirring and high stirring efficiency. To solve the technical problem, the VC adhesive diluting device for the production of the PTP aluminum foils for the medicine package comprises a bottom plate, a support frame, an arc-shaped slide rail, a first slide rod, a support rod, a stirring bucket, a material discharging pipe, a first valve, a material charging pipe, a second valve, a stirring mechanism and the like, wherein the support frame is arranged at the top part of the bottom plate; the upper end of the support frame is connected with the arc-shaped slide rail. The VC adhesive diluting device has the advantages that the stirring mechanism is driven by a rotary mechanism to rotate, a swinging mechanism is controlled to drive the stirring bucket to swing left and right in the stirring process, and the stuck raw material at the inner wall of the stirring bucket can be scraped off by a scrape sheet.
