Description

Technical Field

[0001] The utility model relates to the technical field of printing plate roller production, in particular to a printing plate roller slot inspection tool. Background Art

[0002] The printing plate roller is a key component in the printing press. It is used to transfer printing ink or pigment. It is a roller that can replace the printing plate. The outer wall of the printing plate roller is provided with two slots. The printing plate can be attached to the outer wall of the plate roller by using the card strips and inserted into the slots for limited tensioning, so as to achieve the replacement and fixation of the printing plate, and transfer the pattern or text from the printing plate to the printing medium (such as paper). It is usually made of metal, such as steel, copper or aluminum, with a smooth surface to ensure that the ink is evenly transferred to the printing medium;

[0003] At present, when producing printing plate rollers, it is necessary to inspect the slots of the plate rollers to ensure that the slot size can be tightly plugged into the printing plate clip strip to ensure the stability of the printing plate after it is fixed. Usually, the printing roller shaft is placed on an inspection table and manually measured with a vernier caliper. After measuring different points in the slot, the overall size error of the slot is obtained.

[0004] According to the prior art, a vernier caliper is used to randomly measure the dimensions of multiple points of the card slot, which will increase the inspection error of the inspection structure and affect the quality of the produced printing plate roller. In addition, manual measurement requires re-measurement after each reading, which reduces the work efficiency of inspecting the card slot. Summary of the invention

[0005] In view of the problems in the related technology, the utility model proposes a printing plate roller slot inspection tool to overcome the above technical problems existing in the existing related technology.

[0008] Preferably, the inspection structure includes a pen refill inserted at one end of a mobile inspection frame, a supporting platform welded on the outer wall of the inspection head and a recording paper placed on the upper surface of the supporting platform, and the tip of the pen refill is in contact with the upper surface of the recording paper; by inserting the pen refill at one end of the mobile inspection frame, when the mobile inspection frame moves on the inner wall of the card slot, if the card slot becomes larger or smaller in size, the mobile inspection frame will move on the mobile slot under the tension of the spring, thereby driving the pen refill to draw a line segment of the error size on the recording paper, so as to accurately record the dimensional data of each card slot detection, ensure the accuracy and traceability of the data, and facilitate subsequent analysis and evaluation.

[0009] Preferably, the inspection structure also includes a limit rod welded on the inner wall of the movable groove, the top of the movable inspection frame passes through the limit rod, the spring is sleeved on the outer wall of the limit rod, and the spring is in a stretched state. By inserting the movable inspection frame on the limit rod, the movable inspection frame can be firmly limited, thereby improving the stability of the movement of the bottom end of the movable inspection frame against the inner wall of the slot, thereby improving the sensitivity of the inspection structure detection. At the same time, the spring in a stretched state always generates a certain pulling force on the movable inspection frame, and when it moves to a larger size, it will pull the movable inspection frame to move on the movable groove, so that the change of the degree bar on the scale line can be directly observed.

[0010] Preferably, the pen tip position of the pen core is aligned with the outer wall position on the outer side of the bottom end of the movable inspection frame, and scale lines with the same graduation values ​​are drawn on the recording paper; by setting the pen tip position, the initial position of the pen tip line can be aligned with the initial detection surface of the movable inspection frame to ensure the accuracy of the recorded data, and at the same time, the drawn change line can be coordinated with the scale lines on the recording paper to obtain the error size that is too large or too small.

[0012] Preferably, the inner wall of one side of the card slot of the printing plate roller is vertically fitted with the inspection piece, and the outer wall of the bottom end of the movable inspection frame is fitted with the card slot before the pen core is inserted; by vertically fitting the inner wall of the card slot of the printing plate roller with one side of the inspection piece, the accuracy of the inspection of the horizontally movable inspection structure on the entire card slot can be guaranteed. At the same time, when inserting the pen core during movement, it can be avoided that points or line segments are drawn on the recording paper when the position is adjusted in advance, and the judgment of the detection data by the extra line segments can be avoided.

[0013] Preferably, a lamp tube is provided on the lower surface of the top of the support frame, and the lamp tube is located directly above the printing plate roller; by installing the lamp tube above the printing plate roller, lighting can be provided during inspection, which can improve the clarity of the numerical changes on the scale line of the reading bar, allowing the inspector to observe the changing state more clearly.

[0014] The beneficial effects of the utility model are:

[0015] 1. The printing plate roller slot inspection tool can lower the inspection structure to the slot for inspection through a mobile structure. The inspection head can be moved horizontally by using the mobile structure. During the horizontal movement, if the slot size is too large or too small, the spring will pull the mobile inspection frame to move in the mobile slot. The movement process will cause the position change of the value of the reading bar on the scale line. The size of the slot error can be directly observed, thereby realizing the adaptive adjustment inspection of the inspection structure. When inspecting the full length of the slot, the inspection measurement points are distributed throughout the slot, reducing the error caused by the slot size inspection and improving the quality of the produced products.

[0016] The printing plate roller slot inspection tool inserts a pen core at one end of a mobile inspection frame. When the mobile inspection frame moves on the inner wall of the slot, if the size of the slot becomes larger or smaller, the mobile inspection frame will move on the mobile slot under the tension of the spring, and then drive the pen core to draw a line segment of the error size on the recording paper, so as to accurately record the size data of each slot detection, ensure the accuracy and traceability of the data, and facilitate subsequent analysis and evaluation.

[0017] The printing plate roller slot inspection tool adjusts the inspection head to the inspection state through the extension and retraction of the electric cylinder. The inspector then holds the handle and moves from one end of the slide rail to the other end of the slide rail. Under the action of the slide seat, the inspection head can be driven to slide horizontally on the slide rail to inspect the slot size. The inspection piece and the mobile inspection frame can be used to inspect the overall length of the slot, which improves the convenience of inspecting the slot size and can perform rapid inspections based on specific points in the slot.
