Secondary regulation locking device for chock plug of flexible rotary screen inkjet engraver

Abstract

The invention discloses a secondary regulation locking device for a chock plug of a flexible rotary screen inkjet engraver. The primary regulation locking device comprises a manual regulating mechanism formed by a mill separator, a connecting support bolt set, a fixed support plate, a linear guide rail, a guide rail slider, a movable support plate, a steel band and an eccentric wheel locking device, a rotating shaft, a bearing sleeve, a sliding sleeve, two screw nuts, a support, a screw rod, a circular bearing bush, a motor mounting plate and an electric regulating mechanism of a speed-reducing motor, wherein the support is fixedly connected with the movable support plate of the manual regulating mechanism to form a movable frame. Through the secondary regulation locking device, the requirement that rotary screens with different perimeters and length specifications can be manufactured on the same engraver is met; an eccentric wheel is adopted for locking, and the locking force is directly acted on the fixed support plate to avoid additional acting force on the guide rail and the slider and improve the service life and the reliability of the locking device; and clearances of positive and negative rotation of the screw rod are eliminated by adopting the preloading of the double screw nut combination, and the device has the advantages of compact structure, easy machining of parts, manufacturing cost reduction and convenient assembly.

Description

technical field [0001] The invention relates to a flexible rotary screen ink-jet screen-making machine for textile printing and dyeing, in particular to a secondary adjustment and locking device for the flexible rotary screen ink-jet screen-making machine. Background technique [0002] The rotary screen inkjet screen making machine uses computer control technology and inkjet printing principle to directly print the digital image in the form of simulated liquid droplets on the rotary screen coated with photosensitive adhesive through the printing nozzle, and makes the screen by exposing and washing. version of the device. [0003] There are many different specifications of rotary screens. In practice, there are four specifications commonly used in engineering: 641, 820, 914 and 1018mm in circumference; The screen inkjet screen making machine adopts the cylinder to be set on the cylinder and is driven by the cylinder. The cylinder needs to be replaced for different circumfere...

Problems solved by technology

However, for different lengths of rotary screens, the current rotary screen inkjet screen making machine cannot realize it. In order to meet the screen making requirements of different lengths and specifications of rotary screens, printing and dyeing enterprises must be equipped with different specifications and models of screen making machines

Although there are a few in the market that use movable bulkheads installed on the same guide rail of the inkjet printing head to achieve different lengths of screen making, but due to constraints such as the strength of the guide rail, it is easy to deform under the pressure of inflation, and the accuracy is not easy to guarantee.

At the same time, when loading and unloading, it is necessary to manually adjust the bulkhead, which is inconvenient to operate and low in efficiency
