Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of coating equipment, specifically relates to a preheating device for metal PVD coating production. BACKGROUND
[0002] The PVD coating has better fluidity at a certain temperature range, in order to improve the coating efficiency of the PVD coating, personnel will heat the PVD coating, so as to improve the fluidity of the PVD coating and accelerate the coating efficiency of the PVD coating.
[0003] After searching, it is found that the application number is CN202320516432.2, and the name is a preheating device for PVD coating processing. The application proposes that the PVD coating will adhere to the inner wall of the heating equipment, and as the temperature of the heating equipment rises and the height of the PVD coating in the heating equipment decreases, the adhered PVD coating will dry and harden, the dry and hardened PVD coating will block the conveying pipe, and the heating equipment on the market cannot quantitatively convey the PVD coating, which is easy to cause waste of the PVD coating. The problem is solved by supplying power to the electric heating layer to generate heat and increase the temperature in the preheating cylinder. The motor output end drives the spiral scraper to rotate, and the spiral scraper can scrape off the PVD coating adhered to the inner wall of the preheating cylinder. The spiral scraper is spiral-shaped, so that the spiral scraper scrapes the PVD coating adhered to the inner wall of the preheating cylinder downward, thereby reducing the PVD coating adhered to the inner wall of the preheating cylinder. The dry and hardened PVD coating effectively reduces the dry and hardened PVD coating in the preheating cylinder, prevents the dry and hardened PVD coating from blocking the pipeline, and adjusts the contraction distance of the second cylinder extension end. The piston moves to the right, so that the quantitative cylinder extracts the PVD coating in the preheating cylinder. The contraction distance of the second cylinder extension end is adjusted to control the amount of PVD coating extracted by the quantitative cylinder. The second cylinder extension end is extended, and the PVD coating in the quantitative cylinder is injected into the coating equipment, so that the preheating cylinder has the quantitative conveying capacity of the PVD coating, and the waste of the PVD coating is reduced. However, in actual use, the spiral scraper is in sliding abutment with the inner wall of the preheating cylinder at all times during rotation, which causes friction at all times, resulting in wear and tear at all times, affecting the durability of use and the service life. At the same time, the spiral blade is at the edge of the preheating cylinder, and the stirring efficiency of the central position is not high, which can be further improved.
[0004] For the problems in the related art, no effective solution has been proposed so far. UTILITY MODEL CONTENTS
