Embodiment 2

[0030] This embodiment is a vacuum suction type paper feeding device, as shown in FIG. 1 . The device includes a frame (not shown in the figure). A feed roller 10 composed of a pair of rollers holding cardboard driven by a servo motor 2 installed on the frame. The feeding roller is a pair of rubber rollers installed up and down. The cardboard is clamped by the slit between the two rollers and rolled into the printing machine. The feeding roller in this embodiment is different from the traditional printing machine by mechanical transmission. The feed rollers are driven by servo motors that are uniformly controlled by the press's multi-axis controller for precise multi-color printing. An encoder 1 installed on the shaft end of the servo motor to determine the angular position of the servo motor. This encoder is also related to the entire printing machine, monitoring the angular position of the servo motor at any time in order to synchronize with the entire printing machine. A...

Embodiment 3

[0033] This embodiment is an improvement on the reciprocating mechanism of the second embodiment, as shown in FIG. 3 . The reciprocating mechanism described in this embodiment is a mechanism that realizes the reciprocating motion of pushing the cardboard through a mechanical method, and is an open-loop control mechanism. All movements of the cardboard pusher are deterministic under the constraints of the mechanical mechanism. As long as the accuracy of the mechanical mechanism meets the requirements, it can accurately meet the movement requirements. The reciprocating mechanism described in this embodiment includes: a feed roller driven by a servo motor drives a small gear 601, this small gear drives a large gear 605, and a hinge 602 driving a slider 604 is arranged on the large gear, and the slider is driven by the large gear The gear drives the slide rail in the swinging rocking bar 603, and the swinging bar swings around a hinge 605 fixed on the frame. The other moment arm 6...

Abstract

The invention relates to a vacuum absorption paper-sending method and the device used for paper board printing machine. The device comprises machine frame, sending roller constituted by a pair of rollers clamping paperboard and driven by servo motor, encoder set at the shaft end of servo motor and determining angle position of servo motor, retaining plate set at one side of sending roller, paper pushing plate driven by reciprocating mechanism to move to and fro in narrow slot formed under the retaining plate, journey switch for measuring position of paper pushing plate set on the machine frame and multiple vacuum absorption holes distributed on the paper pushing plate uniformly. The servo motor, the encoder, the journey switch and the electromagnetic valve are connected with multi-axis controller in current. The invention simplifies complicated mechanical transmission mechanism and paper sending performance can be accomplished by electrical control and simple mechanical mechanism. The device is provided with simple structure, small shake, reliable usage and less failure rate. Because of simple mechanical structure, cost is decreased greatly and controlling accuracy is decreased.

Description

technical field [0001] The invention relates to a vacuum adsorption type paper feeding method and device, which is a paper feeding method and device for a cardboard printing machine, and is an electronically controlled mechanical device. Background technique [0002] The vacuum suction type paper feeding device used in traditional cardboard printing machines uses a mechanical method to open and close the vacuum valve. Due to the precise requirement of paper feeding, the opening and closing sequence of the vacuum valve must be very accurate. Moreover, uniform adsorption force is required on the entire surface of the cardboard, that is to say, the vacuum adsorption force must appear or disappear simultaneously on the entire cardboard surface. Based on these requirements, the traditional vacuum suction paper feeder has two boards with through holes punched on the entire surface. When the two boards are overlapped and aligned, the through holes on all two boards are connected t...
