When the upper shield 1 and the lower shield 2 slide upwards to the upper starting point, the weight force born by the whole of the lower shield 2 and the upper shield 1 is smaller than the sum of the thrust of the first air spring 4 to the first swing rod 8 and the thrust of the second air spring 5 to the second swing rod 9, so that the lower shield 2 and the upper shield 1 cannot slide downwards at the upper starting point by themselves.
In order to limit the positions of the lower shield 2 and the upper shield 1 in the paper feeding direction and in the vertical direction, the paper feeding side shield mounting assembly of the invention further comprises a first shield limit bracket 19 and a second shield limit bracket 20 which are identical in structure; the first shield limiting bracket 19 and the second shield limiting bracket 20 are symmetrically arranged on the inner side wall of a rack wallboard of the unit; the first powerful magnet block 24 is arranged on the first shield limit bracket 19, and the second powerful magnet block 25 is arranged on the second shield limit bracket 20; the first shield limiting bracket 19 and the second shield limiting bracket 20 comprise a fixed plate, a limiting plate and a supporting plate, the fixed plate and the limiting plate are integrally formed and mutually perpendicular, and the fixed plate is fixed on a wallboard of the frame; the supporting plate is arranged at the top of the limiting plate and is perpendicular to the fixed plate and the limiting plate; a rectangular frame is arranged at the top of the inner side surface of the lower shield 2; when a detection system corresponding to the lower end elevation of the maintenance and debugging unit is required, the upper shield 1 is turned down to the outer surface of the lower shield 2, then the upper shield 1 and the lower shield 2 are linked and slide upwards to the upper end elevation of the unit together, at the moment, the rectangular frame at the top of the inner side surface of the lower shield 2 is supported by the supporting plate, the inner side surface of the lower shield 2 is limited by the limiting plate, the lower shield 2 is adsorbed by the first powerful magnet block 24 and the second powerful magnet block 25, and the lower shield 2 is fixed at the upper end elevation of the unit.
When the lower shield 2 and the upper shield 1 are slid to the upper end vertical face together, in order to ensure the vertical state of the lower shield 2 and the upper shield 1, a rotating shaft of a first swing rod 8 and a rotating shaft of a second swing rod 9 are arranged on the inner wall surface of the lower shield 2, the first swing rod 8 is connected with the lower shield 2 through the rotating shaft of the first swing rod 8, and the second swing rod 9 is connected with the lower shield 2 through the rotating shaft of the second swing rod 9.
Because the first swing rod 8 is connected with the lower shield 2 through the rotating shaft of the first swing rod 8, and the second swing rod 9 is connected with the lower shield 2 through the rotating shaft of the second swing rod 9, in the process that the first swing rod 8 and the second swing rod 9 drive the lower shield 2 and the upper shield 1 to move upwards, the lower shield 2 and the upper shield 1 can swing around the rotating shafts of the two swing rods, so that the vertical state of the lower shield and the upper shield 1 can be adjusted in time.
In order to facilitate the lower shield 2 to move upwards to the initial point and enable the lower shield 2 to be clung to the vertical surface at the upper end after sliding upwards, the paper feeding side shield mounting assembly of the invention further comprises a first special-shaped guide slide rail 13 and a second special-shaped guide slide rail 14 which are in mirror image relation; the first special-shaped guide sliding rail 13 and the second special-shaped guide sliding rail 14 are respectively arranged on two sides of a rack wallboard of the unit; the two ends of the bottom of the lower shield 2 are correspondingly provided with a first bolt roller needle bearing 21 and a second bolt roller needle bearing, wherein the first bolt roller needle bearing is embedded in the first special-shaped guide sliding rail 13, and the second bolt roller needle bearing is embedded in the second special-shaped guide sliding rail 14; the outer cylindrical surfaces of the first bolt roller needle roller bearing 21 and the second bolt roller needle roller bearing are tangent to the inner wall of the corresponding special-shaped guide sliding rail.
Because the lower end elevation of the paper feeding side of the original hood 28 of the machine set protrudes out of the upper end elevation by a certain dimension, the outer surfaces of the lower shield 2 and the upper shield 1 of the paper feeding side are not coplanar, and after the lower shield 2 and the upper shield 1 slide upwards together, the guide slide rail of the sliding track of the lower shield 2 is parallel to and clings to the upper end elevation of the machine set, and is designed into a special-shaped guide slide rail, namely a first special-shaped guide slide rail 13 and a second special-shaped guide slide rail 14.
It should be noted that, after the inspection system corresponding to the vertical surface at the lower end of the maintenance and debugging unit is maintained, the operator pulls the lower shield 2 to pull the lower shield downward, the lower shield 2 drives the first swing rod 8 to rotate downward around the first swing rod support 10 and the second swing rod 9 to rotate downward around the second swing rod support 11 through the first swing rod rotating shaft 22 and the second swing rod rotating shaft 23 until the lower shield 2 slides down to the lower starting point, and then the upper shield 1 is turned up to the upper starting point.
In order to increase the synchronism and stability of the rotation of the first swing rod 8 around the circle center of the first swing rod support 10 and the rotation of the second swing rod 9 around the circle center of the second swing rod support 11, a first synchronizing shaft 17 is connected between the first swing rod 8 and the second swing rod 9; a second synchronizing shaft 18 is arranged between the first swing rod support 10 and the second swing rod support 11; the first synchronization shaft 17 and the second synchronization shaft 18 have the same structure; the first synchronizing shaft 17 and the second synchronizing shaft 18 each comprise a first section synchronizing shaft and a second section synchronizing shaft, and the first section synchronizing shaft and the second section synchronizing shaft are connected into a whole through a synchronizing shaft locking block.
According to the invention, the first synchronizing shaft 17 is arranged between the first swing rod 8 and the second swing rod 9, so that the synchronism and stability of rotation of the first swing rod 8 around the center of the first swing rod support 10 and the second swing rod 9 around the center of the second swing rod support 11 can be increased, and the stability and smoothness of the paper feeding side lower shield 2 during sliding along the first special-shaped guide sliding rail 13 and the second special-shaped guide sliding rail 14 are ensured.
In order to facilitate lifting the lower shield 2 upwards, the invention is provided with panel locking handles 163 at both ends of the bottom of the outer wall surface of the lower shield 2. When the lower shield 2 needs to slide upwards, an operator pulls the panel lock catch 163 on the lower shield 2 to lift upwards, and the lower shield 2 drives the corresponding swing rod to rotate around the corresponding swing rod support through the rotating shafts of the first swing rod 8 and the second swing rod 9.
It should be explained that the structure and the operation process of the safety shields on the paper output side and the paper input side of the present invention are the same, and are not described herein.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention.
