Description

Technical Field

[0001] The utility model relates to the field of plate roller processing equipment, and particularly relates to an automatic roundness correcting machine. Background Technique

[0002] The manufacturing of printing plate rollers mainly includes four processes: initial coiling, roundness correction, submerged arc welding, and stiffening. These four processes were previously mostly completed manually, so the workload of workers is very large. At present, some enterprises have adopted roundness correcting machines to correct the roundness of plate rollers to be corrected.

[0003] Patent CN116237396A discloses a device and a roundness correction method for plate roller roundness correction. The device includes a machine body, an upper roller and a lower roller arranged in a triangular shape between the two side plates of the machine body, a servo electric cylinder arranged on the upper roller and used to provide the driving force for the up and down movement and the buckling and overturning driving force of the upper roller, and a lower roller servo motor arranged on the lower roller and used to provide the driving force for the self-rotation of the lower roller. However, the above device directly sleeved the plate roller to be corrected on the upper roller, which requires a large operating space and is not convenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic roundness correcting machine to overcome at least one of the defects existing in the above-mentioned prior art. Compared with the parallel feeding of the prior art, the roundness correcting machine of the utility model changes the parallel feeding to inclined feeding. The roundness correcting machine of the utility model raises one end of the upper roller through a pressing component. When inserting the plate roller to be corrected into the upper roller, it can ensure that the outer end of the plate roller to be corrected is also within the machine base area, avoiding that when feeding in parallel, the outer end of the plate roller to be corrected extends into the machine base area, that is, it needs to occupy an area additional to the machine base, thereby effectively utilizing the factory building space; in addition, the roundness correcting machine of the utility model feeds in an inclined manner. When inserting the plate roller to be corrected into the upper roller, the plate roller to be corrected slides into the processing area by gravity, while the prior art needs to manually place the plate roller to be corrected in the processing area, effectively saving manpower.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] An automatic roundness correcting machine, including a machine base, a pair of support seats arranged on the machine base, a pair of lower rollers arranged between the pair of support seats, a lower roller servo motor arranged on the pair of lower rollers and used to provide the driving force for the self-rotation of the pair of lower rollers, an upper roller arranged directly above the pair of lower rollers, and further including:

[0007] A pressing block arranged at one end of the upper roller;

[0008] A locking component arranged on the machine base, and the locking component is connected to the end of the upper roller where the pressing block is not arranged;

[0009] A pressing assembly disposed on the machine base, the pressing assembly including a support frame, a pressing head disposed on the support frame, and a first driving cylinder connected to the pressing head, the pressing head facing the pressing block.

[0010] Further, the pair of lower rollers are arranged in parallel between the pair of support seats.

[0011] Further, the upper roller is parallel to the pair of lower rollers, and the center lines of the upper roller and the pair of lower rollers are respectively located at the three vertices of the same isosceles triangle in the same longitudinal section.

[0012] Further, the upper roller is connected to the locking assembly through a connecting shaft.

[0013] Further, a spherical roller bearing is arranged in the connecting shaft.

[0014] Further, the locking assembly includes a reverse seat pin arranged on the support seat, a second driving cylinder arranged on the machine base, and a connecting rod arranged between the two. One end of the connecting rod is rotatably connected to the reverse seat pin, and the other end is rotatably connected to the second driving cylinder; the reverse seat pin is detachably connected to the upper roller.

[0015] Further, a force-applying rod for facilitating the turning down of the reverse seat pin is arranged on the reverse seat pin.

[0016] Further, a speed reducer is arranged on the lower roller servo motor.

[0017] Further, a gear meshing with the speed reducer is arranged on the lower roller.

[0018] Further, the diameter of the upper roller is smaller than the diameters of the pair of lower rollers.

[0019] Compared with the parallel feeding of the prior art, the utility model has the following beneficial effects:

[0020] (1) By using the pressing assembly to lift one end of the upper roller, when inserting the to-be-roundness-corrected plate roller into the upper roller, it can ensure that the outer end of the to-be-roundness-corrected plate roller is also within the machine base area, avoiding the situation that the outer end of the to-be-roundness-corrected plate roller extends into the machine base area during parallel feeding, that is, an additional area outside the machine base needs to be occupied, thereby effectively utilizing the factory building space.

[0021] (2) The roundness correction machine of the utility model has inclined feeding. When inserting the to-be-roundness-corrected plate roller into the upper roller, the to-be-roundness-corrected plate roller is slid into the processing area by using gravity, while the prior art parallel feeding requires manually placing the to-be-roundness-corrected plate roller in the processing area, effectively saving labor.

The upper roller 4 is parallel to the pair of lower rollers 3, and the center lines of the upper roller 4 and the pair of lower rollers 3 are respectively located at the three vertices of the same isosceles triangle in the same longitudinal section. Among them, the diameter of the upper roller 4 is smaller than the diameter of the pair of lower rollers 3.

[0034] In this embodiment, the upper roller 4 is connected to the locking assembly through a connecting shaft 9. The locking assembly includes an inverted seat bolt 10 arranged on the support base 2, a second driving cylinder 12 arranged on the machine base 1, and a connecting rod 11 arranged between the two. One end of the connecting rod 11 is rotatably connected to the inverted seat bolt 10, and the other end is rotatably connected to the second driving cylinder 12; the inverted seat bolt 10 is detachably connected to the upper roller 4.

[0037] Working principle:

[0038] Compared with the parallel feeding of the prior art, the rounding machine in this embodiment changes the parallel feeding to inclined feeding.

[0040] After the plate roller to be rounded slides into the processing area, turn up the inverted seat bolt 10 until it is buckled with the connecting shaft 9 to ensure that the plate roller to be rounded is in contact with the lower roller 3. The lower roller 3 starts to round the plate roller to be rounded sleeved on the upper roller 4. After completion, turn down the inverted seat bolt 10. The pressing head 7 of the pressing assembly abuts against the pressing block 5 to lift one end of the upper roller 4, take out the rounded plate roller, put in the plate roller to be rounded, and repeat the above steps.

[0041] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
