Spraying machine for inner wall of bottle body

Abstract

The invention discloses a spraying machine for the inner wall of a bottle body. The spraying machine comprises a rack; a bottle body placement seat for placing a bottle body, a bottle body fixing mechanism matched with the bottle body placement seat for axially fixing the bottle body and circumferentially rotating and a spraying mechanism for spraying the inner wall of the bottle body are arrangedon the rack; a screw rod is vertically arranged on the rack, and the screw rod is provided with a first thread section and a second thread section with the same rotation direction from top to bottom;the length of the first thread section is larger than that of the second thread section; the bottle body fixing mechanism is arranged on the first thread section through a first lifting frame; and the spraying mechanism is arranged on the second thread section through a second lifting frame. The first thread section and the second thread section with the same rotation direction and with differentlengths are arranged on the screw rod, while the bottle body fixing mechanism and the spraying mechanism are driven to lift at the same time, the bottle body fixing mechanism and the spraying mechanism are ensured to reach predetermined positions successively, the structure is simple, the driving force is saved, and operation of each mechanism is highly consistent.

Description

technical field [0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a bottle inner wall spraying machine. Background technique [0002] For bottles (such as fire extinguishers) that are used to hold corrosive substances, it is often necessary to spray the inner wall of the bottle to isolate the corrosion of the corrosive substance to the bottle. The Chinese invention patent application with the application number CN201610596682.6 discloses a spraying machine for the inner surface of the bottle body. The inner surface spraying machine includes a frame. And the bottle body placement mechanism that makes the bottle body rotate in the circumferential direction. The frame is provided with a lift frame through the first lifting drive mechanism. A spraying mechanism that sprays into the bottle and sprays the inside of the bottle; the bottle placement mechanism includes a bottle placement seat and an upper seat above the bottle pl...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of this inner surface spraying machine is that when spraying, it is necessary to use the second lifting drive mechanism to drive the upper seat down, fasten the upper cover on the bottle body, and then use the first lifting drive mechanism to drive the lifting frame down, so that The spraying mechanism is inserted into the bottle body; the upper cover and the spraying mechanism are respectively driven by two lifting drive mechanisms, which need to be controlled separately, which not only requires high operating costs, but also tends to run asynchronously
