Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
The liftable printing roller bracket comprises two first support plates 1, two second support plates 2, two support plates 3, a plurality of connecting rods 4 and a power mechanism. The two first supporting plates are horizontally arranged in parallel at a certain interval; the distance between the two first supporting plates is matched with the width of the carrier, so that the carrier can be smoothly pushed into the space between the two first supporting plates. The two second support plates are respectively vertically arranged on the two first support plates and correspond to each other in position (namely, the plane where the central lines of the two second support plates are located is vertical to the central line of the first support plate).
The two supporting plates are arranged along the length direction of the first supporting plate, and are respectively arranged right above the two first supporting plates. A plurality of groups of riding wheels 7 which are arranged at certain intervals are correspondingly arranged on the surfaces of the two supporting plates respectively; the distance between two riding wheels in each group of riding wheels is less than the length of the plate roller; the distance between two adjacent supporting wheels on each supporting plate is smaller than the diameter of the plate roller, so that the plate roller is supported by two adjacent groups of supporting wheels, and the plate roller is clamped and fixed conveniently. The riding wheel is made of elastic material, preferably rubber material.
A plurality of connecting rods are hinged between each group of corresponding first support plates and the supporting plate (in the figure, 12 connecting rods are hinged between each group of first support plates and the supporting plate, and the 12 connecting rods are correspondingly arranged on the inner walls of the two sides of the first support plates and the supporting plate in pairs); all the connecting rods are the same in length and parallel to each other, so that the first support plate, the supporting plate and any two connecting rods on the same side form a parallelogram mechanism. The maximum height of the printing roller for lifting is the length of the connecting rod, so that the length of the connecting rod is suitable for the maximum height of the printing roller to be lifted, and the printing roller can be smoothly carried between the carrier and the bracket.
The power mechanism is used for driving the supporting plate to lift; the power mechanism and the supporting plate are respectively arranged at the left side and the right side of the second supporting plate (as shown in fig. 2, the power mechanism is arranged at the left side of the second supporting plate, and the supporting plate is arranged at the right side of the second supporting plate, wherein the left side and the right side are both the left side and the right side of fig. 2).

The power mechanism is respectively connected with the two supporting plates through two groups of pulley blocks. The two groups of pulley blocks have the same structure; each group of pulley blocks comprises a first fixed pulley 6-1, a second fixed pulley 6-2, a movable pulley 6-3 and a rope 6-4. The first fixed pulley and the second fixed pulley are both rotatably hinged on the second support plate (in the figure, the first fixed pulley and the second fixed pulley are arranged on the same hinged shaft); the movable pulley is rotatably hinged on the supporting plate. The two ends of the rope are respectively fixedly connected with the rotating shaft and the supporting plate; wherein, rope one end is fixed in the axis of rotation (also can fix a capstan winch on the axis of rotation, and rope one end is fixed in the capstan winch), and the other end is walked around first fixed pulley, movable pulley and second fixed pulley in proper order, fixes on the layer board at last. Through holes 8 are formed in the positions, corresponding to the two fixed pulleys, of the first support plate and the movable pulleys and in the positions, corresponding to the movable pulleys, of the support plate, so that a rope can conveniently penetrate through the through holes.
To facilitate the carriage movement, a moving wheel (not shown) may also be mounted at the bottom of the first support plate.
The first support plate, the second support plate and the support plate are all made of steel beams; the fixed connection part of the first support plate and the second support plate is fixed in a welding mode.
Finally, it should be noted that the above-mentioned embodiments illustrate only specific embodiments of the invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
