Description

Technical Field

[0001] The utility model relates to the technical field of workpiece detection, in particular to a coaxial detection device for a plate roller. Background Art

[0002] The plate roller is a key component in a printing press used to support and rotate the printing plate. It is usually covered with rubber or other special materials to ensure printing quality. In order to ensure accuracy and quality during the printing process, coaxial detection equipment must be used to ensure that the axis of the plate roller is perfectly aligned with the other axes of the printing press. Any deviation of the axis may cause printing errors such as blurred images or overprinting. Therefore, coaxial detection is essential to maintaining printing quality and efficiency. In this way, deviations can be adjusted and corrected in a timely manner to ensure the continuity of printing operations and the consistency of products.

[0003] When the existing coaxial detection equipment for printing plate rollers is working, the screw is first twisted to drive the clamping plate to move and fix the printing plate roller, and then the sensor is driven to move along the length direction of the printing plate roller through the moving mechanism to measure the diameter and position of its axis in real time. The measurement data is sent to the analysis software, and the software will calculate any axis deviation or bending. However, the traditional coaxial detection equipment for printing plate rollers does not take into account the problem that the curvature of the clamping plate is fixed, resulting in the problem that only printing plate rollers of a single diameter can be fixed. Therefore, a coaxial detection equipment for printing plate rollers is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] After the distance between the support seats 2 is adjusted, place the plate roller above the clamping arm 8, press it downward, so that the clamping arm 8 rotates around the fixed axis 7, and the slide plate 4 moves downward. As the slide plate 4 moves downward, the spring 5 will be subjected to the pressure from the plate roller and begin to shrink. When the spring 5 shrinks to a certain extent, it will generate a supporting force due to the reverse force of reset. This supporting force will stably limit the plate roller to the position between pulley two 10 and pulley three 11. After the placement of the plate roller is completed, start the motor 15 to drive the screw rod 16 to rotate, so that the sliding block 17 moves. As the sliding block 17 moves, it will drive the laser detector 18 to move accordingly, so as to detect the state of the plate roller. The laser detector 18 is an existing searchable technology and will not be described in detail here.

[0033] Reference Figure 4 A guide rod 19 is fixedly connected inside the bottom plate 1, and a slider 20 is slidably connected to the side wall of the guide rod 19. The side wall of the slider 20 is slidably connected to the inside of the bottom plate 1. A fixing seat 25 is fixedly connected to the upper surface of the slider 20. The side wall of the fixing seat 25 is slidably connected to the upper surface of the bottom plate 1. The side wall of the support seat 2 is fixedly connected to the upper surface of the fixing seat 25. A positioning column 22 is fixedly connected inside the bottom plate 1. The positioning column 22 is arranged in the middle of the guide rod 19. The side wall of the positioning column 22 is rotatably connected to a connecting plate 23. A connecting plate 1 21 is rotatably connected inside the fixing seat 25. One side of the connecting plate 1 21 is rotatably connected to the side wall of the connecting plate 23. A hydraulic rod 24 is fixedly connected to the side wall of the bottom plate 1, and the output end of the hydraulic rod 24 is fixedly connected to the side wall of the slider 20 on one side.

[0034] When the device is used to detect the coaxiality of the plate roller, the hydraulic rod 24 can be started to push the slider 20 on one side to move horizontally. As the slider 20 moves, it will cause the connecting plate 1 21 connected thereto to deflect, and this deflection will then be transmitted to the connecting plate 23, causing it to rotate on the positioning column 22. The rotation of the connecting plate 23 will further cause the connecting plate 1 21 on the other side to deflect, and synchronously drive the slider 20 on the other side to move accordingly. When the sliders 20 on both sides move to the middle position at the same time, the distance between them will decrease, thereby achieving the effect of adjusting the distance between the left and right support seats 2 according to the length of the plate roller.

[0035] Working principle: When the device is used for coaxial detection of the plate roller, first start the hydraulic rod 24 to push the slider 20 on one side to move, and make the connecting plate 1 21 on this side deflect, thereby driving the connecting plate 23 to rotate on the positioning column 22, and then making the connecting plate 1 21 on the other side deflect, and synchronously driving the slider 20 on the other side to move. When the sliders 20 on both sides move synchronously in the middle, the effect of adjusting the distance between the left and right support seats 2 is achieved. When the distance adjustment is completed, the plate roller is placed between the clamping arms 8 and pressed downward to make the clamping arms 8 rotate on the fixed shaft 7 and make the slide plate 4 slide downward, causing the spring 5 to contract under pressure. The reverse force generated by the reset of the spring 5 will support the plate roller, so that the plate roller is restricted between the pulley 2 10 and the pulley 3 11. After the plate roller is placed, start the motor 15 to drive the screw 16 to rotate, so that the sliding block 17 drives the laser detector 18 to move, and the plate roller is detected.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
