Description

Technical Field

[0001] The utility model relates to a cold stamping machine, in particular to a deviation correcting device of a full-automatic silk-screen cold stamping machine. Background Art

[0002] At present, a Chinese patent with authorization announcement number CN208392848U discloses a screen printing sheet-fed cold stamping machine, which includes a paper feeding section sequentially connected to a screen printing and gluing section, an ultraviolet light curing section, a cold stamping section and a paper receiving section.

[0003] Among them, the cold stamping part includes an impression roller, a lower synchronous conveying roller, an upper synchronous conveying pressure wheel, a rubber roller, a cold stamping mechanism, a foil passing roller, a cold stamping foil conveying mechanism, a cold stamping foil roll driving servo motor, a driving gear, a cold stamping foil roll air expansion shaft, a cold stamping electrochemical aluminum foil roll, a driven gear, a waste cold stamping foil roll air expansion shaft, a waste cold stamping foil roll, a driven gear, a driving gear, a waste cold stamping foil roll driving servo motor, a cold stamping electrochemical aluminum foil, a foil passing shaft, an upper paper transfer roller, a lower paper transfer roller and a suction paper collection conveyor belt.

[0004] The printed product is fed between the lower synchronous conveying roller and the upper synchronous conveying pressure wheel arranged up and down. The cold foil mechanism is also equipped with a rubber roller and an impression roller arranged vertically up and down. The lower synchronous conveying roller and the upper synchronous conveying pressure wheel rotate synchronously in opposite directions to feed the printed product between the rubber roller and the impression roller. A cold foil conveying mechanism is installed above the cold foil mechanism. There are two cold foil roll air expansion shafts driven by servo motors on the cold foil conveying mechanism. The cold foil roll air expansion shaft is equipped with cold foil electrochemical aluminum foil rolls. The waste cold foil roll air expansion shaft is used to collect the waste cold foil rolls. The shaft is installed to recycle waste cold foil rolls. The cold foil anodized aluminum foil passes through multiple foil rollers and foil rollers to bypass the rubber cylinder and is wound on the air expansion shaft of the waste cold foil roll. Driven by the driving servo motor of the air expansion shaft of the waste cold foil roll, the anodized aluminum foil is synchronously wound on the air expansion shaft of the waste cold foil roll. The printed products after cold foil processing enter between the upper paper transfer roller and the lower paper transfer roller arranged up and down, and are clamped by the upper paper transfer roller and the lower paper transfer roller rotating synchronously, and are transported to the paper collection department through the suction paper collection conveyor belt.

[0005] However, the papers are transported one by one. During the process of the lower synchronous conveying roller and the upper synchronous conveying pressure wheel rotating towards each other to feed the printed products between the rubber cylinder and the impression cylinder, the suction paper conveyor belt will inevitably vibrate during the rotation, causing the position of the paper to shift. This will cause the cold stamping film to shift when covering the paper, which will affect the production quality. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a deviation correction device for a fully automatic silk screen cold stamping machine to achieve the purpose of improving production quality.

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a correction device for a fully automatic silk-screen cold stamping machine, comprising a conveyor roller, a conveyor belt and a frame fixed on the cold stamping machine body, a plurality of the conveyor rollers are rotatably connected to the frame, the plurality of the conveyor rollers are arranged in parallel, the conveyor belt is tensioned by the conveyor rollers, a plurality of conveyor belts are arranged, the conveyor belt is in contact with the upper surface of the frame, a limit cylinder is fixedly connected to the frame, a fixed plate is connected to the power shaft of the limit cylinder, a plurality of baffles are connected to the fixed plate, a plurality of connecting grooves are provided on the upper surface of the frame, the baffles extend from the connecting grooves and are used to contact the ends of the paper, and the conveyor belt passes between two adjacent baffles.

[0008] To implement the above technical solution, the paper is placed on the conveyor belt. As the conveyor roller rotates, the paper moves with the conveyor belt and collides with the baffle rod. As the conveyor belt continues to rotate, the end of the paper is in a straight state when it collides with multiple baffle rods. At this time, the limit cylinder is turned on, and all the baffle rods are moved synchronously through the fixed plate to separate the baffle rod from the paper. At this time, the paper is in a straight state and is transmitted along the conveyor belt, thereby achieving the effect of paper correction to achieve the purpose of improving quality.

[0009] As a preferred solution of the utility model, a mounting hole is provided on the frame, the mounting hole is located between a plurality of baffles, an infrared emitter is fixedly connected to the frame, the infrared emitter is installed in the mounting hole, and the infrared emitter is electrically connected to the limit cylinder through a controller;

[0010] After the paper covers the infrared transmitter, the limit cylinder is activated and moves the stopper to separate from the paper.

[0011] To implement the above technical solution, paper is placed on the conveyor belt, and the conveyor belt rotates to make the end of the paper collide with the baffle rod. As the conveyor belt continues to rotate, the end of the paper collide with all the baffle rods due to the action of friction. At this time, the paper covers the infrared transmitter, indicating that the paper has been straightened. The infrared transmitter sends an electrical signal to the controller, and the controller sends an electrical signal to the limit cylinder. The limit cylinder starts and pulls the baffle rod out of the connecting groove, so that the paper can continue to be conveyed with the conveyor belt, thereby achieving the effect of automatic deviation correction and improving practicality and convenience.

[0013] To implement the above technical solution, the paper is placed on the conveyor belt. When the lateral offset distance of the paper is too large, the auxiliary cylinder is turned on, the support wheel passes through the auxiliary hole and contacts the inner wall of the conveyor belt, lifts up the conveyor belt, and uses gravity to make the paper offset a large distance to achieve a large range of correction effect, to ensure that the end of the paper can contact the stop rod, thereby achieving a double correction effect, which greatly improves production quality.

[0014] As a preferred solution of the utility model, a slide groove is provided on the fixed plate, the length direction of the slide groove is parallel to the conveying direction of the paper, the end of the baffle rod is connected to a slider slidably connected to the slide groove, and the slider is fixed to the slide groove by a positioning mechanism.

[0015] To implement the above technical solution, the slider is moved along the length direction of the slide groove, and the baffle rod moves synchronously with the slider so that the position of the baffle rod can be changed. The slider is then fixed to the slide groove through a positioning mechanism to achieve the positioning of the baffle rod. At this time, through the cooperation of multiple baffle rods, it can adapt to papers of different shapes, greatly improving practicality.

[0016] As a preferred solution of the utility model, the positioning mechanism includes a locking hole and a locking bolt, the locking hole is opened on the lower surface of the fixed plate and is connected to the slide groove, and the locking bolt is threadedly connected in the locking hole and is used to tighten against the slider.

[0017] To implement the above technical solution, the locking bolt is rotated, and the locking bolt moves along the axial direction of the locking hole and is used to press against the slider, and the slider is positioned by the friction force, which is easy to operate.

[0018] As a preferred solution of the utility model, an eccentric column is fixedly connected to the end of the blocking rod, the eccentric column is threadedly connected to the slider, a locking sleeve is threadedly connected to the eccentric column, and the locking sleeve is used to press against the slider.

[0019] To implement the above technical solution, the baffle rod is rotated along the axis of the eccentric column, and then the locking sleeve is tightened against the slider to achieve the positioning of the baffle rod, so that the distance between two adjacent baffle rods can be adjusted to adapt to papers of different shapes, thereby further improving practicality.
