Printing machine flash oven height synchronous adjustment mechanism

Abstract

A height synchronous adjustment mechanism for a flash oven of a printing machine, including a frame, ear seats, threaded sleeves, screws, synchronous sprockets, chains, handwheels, and a flash oven. The four ear seats are symmetrically arranged on the left and right sides of the flash oven, and the flash oven The center of gravity is supported by four threaded sleeves, and a synchronous sprocket is fixedly installed on the upper end of each screw, and is in the same plane. The chain is set on the four synchronous sprockets, and the lower end of the screw is rotatable through the limit seat Fixed on the frame, with a hand wheel on a screw rod. As long as any one of the synchronous sprockets is rotated, the other three synchronous sprockets will rotate at the same time. Since the synchronous sprockets are fixedly installed on the screw, the rotation of the synchronous sprocket will drive the screw to rotate, thereby driving the threaded sleeve to rise and fall to realize the lifting of the flash oven. Adjustment, in the process of lifting, the movement is smooth, and there will be no crawling phenomenon. Since the hand wheel is set above the flash oven, the operation is very convenient.

Description

Technical field: [0001] The invention relates to a flash oven part of a printing machine, in particular to a height adjustment mechanism of the flash oven part. Background technique: [0002] The printing machine includes a transfer table, a printing head, a flash oven and a transmission mechanism for the translation of the transfer table. The printed fabric is pasted on the transfer table. The directional translational transmission between each printing head ensures accurate positioning when the transfer table is transferred to the corresponding printing heads, so as to meet the accurate printing requirements of various colors during color printing; there are screen frames and scrapers on the printing heads And the scraper action mechanism, the printing head can complete the screen printing work according to the requirements of screen printing; the flash oven is set at the next station of the printing head, and its function is to surface the printing ink formed on the fabri...

Problems solved by technology

Depend on figure 1 , figure 2 It can be seen from the structure shown that the support mode of the existing flash oven 1 is a unilateral overhanging support structure. Although the flash oven 1 is adjusted by the screw nut lifting adjustment mechanism to realize synchronous lifting adjustment, the force of the two guide rods 2 is unreasonable. The force between the guide rod 2 and the guide sleeve 4 is unilateral, and the resistance of the flash oven 1 is relatively large when it rises or falls, and the stability of the movement is very poor, which is prone to crawling

At the same time, the lifting hand wheel 7 is arranged in the middle of the two guide sleeves 4, and is located in the lower section, so the operating space is small and the operator is very inconvenient
