Description

Technical Field

[0001] The utility model relates to the technical field of pressure roller detection, in particular to a pressure roller performance detection device. Background Art

[0002] Pressure rollers are a common component in industrial equipment, usually used to process, convey or flatten materials during the production process. These rollers are usually made of metal and have wear and corrosion resistance to ensure their stability and reliability in long-term use. Pressure rollers are widely used in production lines in industries such as steel, papermaking, printing, plastic processing, textiles, glass, etc.

[0003] When testing the performance of existing pressure rollers, the main test is on their anti-bending strength. However, during the use of the pressure rollers, friction will occur with the workpiece, and in the continuous production process, the friction will last for a long time and the wear will be more serious, which will change the diameter of the pressure roller and affect the processing accuracy. Therefore, it is necessary to test the wear resistance of the pressure roller in order to control and save costs, but the existing market lacks a device for testing the wear resistance of the pressure roller.

[0004] Therefore, the utility model provides a pressure roller performance detection device to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a pressure roller performance detection device that solves the above-mentioned problems. By energizing the electromagnet to generate magnetic force, the limit block compression spring is moved, thereby releasing the restriction on the plug block, and then the plug block is pulled out through the pull ring, and then the pressure roller to be detected can be placed in the circular groove of the assembly block. After that, the plug block is reinserted and the electromagnet is powered off to lose its magnetic force. Under the action of the spring elastic force, the limit block will restrict the plug block again, and then the pressure roller will be fixed. After that, the servo motor is started to drive the pressure roller. The worm gear can then drive the first rotating shaft and the connecting rod to rotate, and the rotating drum is brought close to the pressure roller, and they will rotate together under the action of the friction force. In this way, with long-term continuous rotation, the normal service life of the pressure roller can be obtained by measuring the smoothness of the surface and the change of the diameter of the pressure roller. The ultrasonic flaw detector is moved downward by starting the electric telescopic rod, and it can be started to detect the pressure roller when it contacts the pressure roller, so as to find out whether there are slight cracks in the pressure roller.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a pressure roller performance detection device, comprising a base, a friction detection component is arranged on one side of the base; an auxiliary detection component is also arranged on the outer side of the base; the friction detection component comprises a support plate, the support plate is fixedly connected to one side of the base, one side of the support plate is rotatably connected to a second rotating shaft, one end of the second rotating shaft is fixedly connected to an assembly block, an insertion block is inserted into the interior of the assembly block, an auxiliary block is fixedly connected to the top of the base, a worm is rotatably connected between the two auxiliary blocks, one end of the worm is fixedly connected to a turntable handle, one side of the support plate is rotatably connected to a first rotating shaft, an outer wall of the first rotating shaft is fixedly connected to a connecting rod, a rotating drum is rotatably connected between the two connecting rods, one end of the first rotating shaft is fixedly connected to a worm wheel, the worm wheel is meshed with the worm, a servo motor is fixedly installed on one side of the support plate, and the output shaft of the servo motor is fixedly connected to one end of the second rotating shaft.

[0007] Furthermore, an electromagnet is fixedly installed inside the assembly block, both ends of the electromagnet are fixedly connected to springs, one end of the spring is fixedly connected to a limit block, and the limit block is inserted into the interior of the insertion block.

[0008] By adopting the above technical solution, the insert block can be restricted to prevent it from falling off.

[0009] Furthermore, one end of the limit block and one end of the insert block need to be processed into arc surfaces.

[0010] By adopting the above technical solution, the resistance is reduced when the inserting block is inserted into the assembly block.

[0011] Furthermore, a pull ring is fixedly connected to the top of the insert block.

[0012] By adopting the above technical solution, it is convenient to pull out the plug block.

[0013] Furthermore, the auxiliary detection component also includes a concave frame, and an electric telescopic rod is fixedly installed on the top of the inner wall of the concave frame.

[0014] The above technical solution is used to install an ultrasonic flaw detector.

[0015] Furthermore, an ultrasonic flaw detector is fixedly installed on the movable end of the electric telescopic rod.

[0016] By adopting the above technical solution, the pressure roller is inspected by an ultrasonic flaw detector.

[0017] Beneficial Effects

When the rotating drum is brought close to the pressure roller, they will rotate together under the action of the friction force. In this way, with long-term continuous rotation, the normal service life of the pressure roller can be obtained by measuring the smoothness of the surface and the change in the diameter size.

[0021] 2. The pressure roller performance detection device moves the ultrasonic flaw detector downward by starting the electric telescopic rod.
