A bottle silk screen printing process using a circular conveying line

Abstract

The invention relates to a bottle body silk-screen process employing a cyclic conveying operating line. The process comprises the following steps: loading and positioning; clamping and overturning; clamping; resetting by a manipulator; flame treatment; pre-positioning; printing oil printing; scraper resetting; printing oil curing; gliding and unloading. According to the process provided by the invention, an intelligent cyclic line system is adopted when printed materials are conveyed. The intelligent cyclic line comprises a station cyclic conveying operating line and rotors; the transmission system is precise to position repeatedly (+ / -10 [mu]m). A clamp on each rotor clamps at one time till all printing flows are completed, then the clamp is released to wait for unloading or gliding to unload, and the plurality of rotors can be mounted on one station cyclic conveying operating line, so that the bottle body silk-screen process is safe, reliable and low in noise, improves the overprintprecision, the printing quality and the working efficiency. In addition, the failure rate is also relatively low. Printing oil on a bottle body is cured by adopting ultraviolet rays or electronic beams. During use, the printing oil is cured by using an LED lamp which is 300-400 watts. The LED lamp is turned on and off immediately: the LED lamp is turned on when the bottle is cured and the LED lampis turned off when the bottle is not available, so that the energy source is saved effectively.

Description

technical field [0001] The invention belongs to the technical field of screen printing, and relates to a bottle body screen printing process using a circulating conveying line. Background technique [0002] As we all know, to complete single-color or multi-color screen printing on existing bottle body screen printing machines, a mechanical transmission mechanism is required to transport the bottle (or other substrates) from the previous station to the next station step by step. Because the substrate has to be clamped and loosened many times, and only one color is printed, it has to be handled more than a dozen times from loading to unloading, and transmission errors often occur, especially when printing glass bottles, because glass bottles are hard and Fragile, and the edges of the fragments are extremely sharp. When they fall during the transportation process, they are squeezed or impacted by the transportation mechanism, causing the bottle body to break and crack, and the ...

[0002] As we all know, to complete single-color or multi-color screen printing on existing bottle body screen printing machines, a mechanical transmission mechanism is required to transport the bottle (or other substrates) from the previous station to the next station step by step. Because the substrate has to be clamped and loosened many times, and only one color is printed, it has to be handled more than a dozen times from loading to unloading, and transmission errors often occur, especially when printing glass bottles, because glass bottles are hard and Fragile, and the edges of the fragments are extremely sharp. When they fall during the transportation process, they are squeezed or impacted by the transportation mechanism, causing the bottle body to break and crack, and the fragments splash around, which will cause serious injury to the machine or personnel. Therefore The handling speed cannot be too fast, the work efficiency is low and the failure rate is high; because of the high number of clamping times, dozens of clamping mechanisms clamp the bottle at the same time according to the beat, resulting in a lot of noise; in addition, the existing screen printing machine uses 3 kW to 5 Kilowatt high-pressure mercury lamp curing method to cure ink, high energy consumption, does not meet the current environmental protection concept of energy saving and emission reduction
