Correspondingly, the backing plate 4 is provided with an adjusting screw hole 4-1 for mounting an adjusting screw 5, and the hole wall of the backing plate is provided with a threaded inner wall matched with the cylinder 5-2 of the adjusting screw 5, so that the adjusting screw 5 and the adjusting screw hole 4-1 can be mounted conveniently, and the adjusting screw 5 is further arranged in the backing plate 4.

Furthermore, filling glue for preventing the adjusting screw 5 from falling off the backing plate 4 is arranged between the cylinder 5-2 of the adjusting screw 5 and the adjusting screw hole 4-1. The filling adhesive is made of anaerobic adhesive or other replaceable adhesives, once the anaerobic adhesive is isolated from air, the anaerobic adhesive can be polymerized and cured at room temperature to form a hard adhesive layer, so that the column 5-2 and the adjusting screw hole 4-1 are firmly glued and sealed. Those skilled in the art can flexibly design the material of the filling adhesive to achieve the same effect, which is not repeated herein.

It can be understood that the through hole 2-1 of the pressure plate 2 and the adjusting screw hole 4-1 of the backing plate 4 are mutually matched and are positioned on the same axis. When the pressing plate 2 and the backing plate 4 are assembled, the plurality of through holes 2-1 of the pressing plate 2 correspond to the plurality of adjusting screw holes 4-1 of the backing plate 4 one by one, so that one core rod 1 is arranged between the corresponding adjusting screw hole 4-1 and the through hole 2-1, the core rod 1 is allowed to penetrate out of the pressing plate 2 from the through hole 2-1, and meanwhile, the adjusting screw 5 matched with the core rod 1 can also be placed in the backing plate 4 through the adjusting screw hole 4-1 of the backing plate 4, so that the column head 5-1 of the adjusting screw 5 is in contact with the lower end face of the rod seat 1-1 of the core rod 1. Therefore, for one core rod 1, the axial lifting of the core rod 1 can be adjusted by adjusting the adjusting screw 5 in the corresponding adjusting screw hole 4-1 of the backing plate 4.

Further, the rod seat 1-1 of the core rod 1 is of a cylindrical structure, and the outer diameter of the rod seat is larger than that of the column head 5-1 of the adjusting screw 5, so that the column head 5-1 effectively contacts the lower end face of the rod seat 1-1; usually, the radial dimension of the rod seat 1-1 can also be slightly larger than the radial dimension of the corresponding adjusting screw hole 4-1, so as to prevent the rod seat 1-1 from falling into the adjusting screw hole 4-1.

Referring to fig. 1, 2, 3 and 4, the nut surface of the mounting screw 6 has an inner hexagonal groove, an inner tetragonal groove, a cross groove, a straight groove or a similar structure suitable for controlling rotation, when the backing plate 4 and the pressing plate 2 are mounted and combined, the mounting screw 6 is inserted into the mounting hole 4-2 on the opposite surface of the backing plate 4 and the pressing plate 2, and then is screwed into the corresponding mounting hole 2-2 of the pressing plate 2, so as to lock the backing plate 4 and the pressing plate 2.

Furthermore, the opposite surface of the backing plate 4 opposite to the pressing plate 2 is provided with a groove 4-3, correspondingly, the opposite surface of the pressing plate 2 opposite to the backing plate 4 is also provided with a groove 2-3, specifications of the two book grooves 4-3 and 2-3 are matched with each other, and after the backing plate 4 and the pressing plate 2 are screwed and locked through the mounting screw 6, an accommodating cavity 7 is formed between the groove 4-3 and the groove 2-3.

Referring to fig. 1 and 5, the receiving cavity 7 formed by the grooves 4-3 and the grooves 2-3 is a development window through which the rod seat 1-1 of the core rod 1 and the elastic rubber pad 3 combined with the pressing plate 2 can be observed, so as to observe the relative positions of the rod seat 1-1 of the core rod 1 and the elastic rubber pad 3 and the pressing plate 2 adjusted by the adjusting screw 5.

Referring to fig. 1 and 2, the backing plate 4 is provided with tablet press mounting holes 4-4, and correspondingly, the pressing plate 2 is provided with tablet press mounting holes 2-4 corresponding to the tablet press, when the gasket 4 is screwed with the pressing plate 2, the tablet press mounting holes 4-4 and 2-4 of both sides are in one-to-one correspondence, so that the core bar adjusting structure and the tablet press are conveniently mounted.

Referring to fig. 1 and 5, during installation, the elastic rubber pad 3 is sleeved on the core rod 1 to contact with the upper end surface of the rod seat 1-1 of the core rod 1, and then the core rod 1 passes through the through hole 2-1 of the pressing plate 2, so that the rod seat 1-1 and the elastic rubber pad 3 are placed in the accommodating cavity formed by the pressing plate 2 and the backing plate 4. According to the structure, after each core rod is installed one by one, the pressure plate 2 and the backing plate 4 are screwed through the installation screw 6, and the adjusting screw 5 is placed into the adjusting screw hole 4-1 opposite to the through hole 2-1 in the backing plate 4, at this time, the upper end surface of the column head 5-1 of the adjusting screw 5 is not contacted with the lower end surface of the rod seat 1-1 of the core rod 1, and the elastic rubber pad 3 is compressed to deform, so that the upper end surface of the column head 5-1 of the adjusting screw 5 is contacted with the lower end surface of the rod seat 1-1 of the core rod 1 and keeps a certain pretightening force, the core rod 1 will not shake, and at the same time, the adjusting screw 5 is not easy to rotate because the filling rubber is arranged between the adjusting screw 5 and the backing plate 4, keeping it unchanged in the position in which said pad 4 is placed.

Further, when the protruding length of the core rod 1 of the core rod adjusting structure 10 needs to be adjusted, the adjusting screw 5 corresponding to the core rod 1 can be rotated by using a hexagonal screwdriver adapted to the adjusting screw 5, so that the height of the core rod 1 is increased to the dimension Δ Z required to be adjusted. When the relative height of a certain core rod 1 needs to be adjusted to be shortened, the corresponding adjusting screw lock 5 is adjusted firstly, and when the adjusting screw lock is not adjusted in place, other adjusting screws 5 are adjusted to enable the core rod to be lifted to the required size.

In the practical use process, due to the different depths of the blind holes of the filter, or due to the manufacturing requirement, the extending lengths of the core rods 1 may be at least partially different, for example, the extending height (length) of one of the core rods 1 is slightly larger than the extending height (length) of the other core rod 1, and the height difference is partially determined by the length of each core rod 1 itself and partially determined by the fine adjustment function of the adjusting screw 5 corresponding to the core rod 1 in the invention.

It can be seen from the above description of the core rod adjusting structure and the installation process and adjusting process thereof of the present invention that in the structure, the relative heights of the core rods can be independently adjusted, and the extension lengths of the core rods can be adjusted by adjusting the adjusting screws opposite to the core rods.
