Description

Technical Field

[0001] This utility model relates to a device for enhancing the stable operation of an online steel stamping machine, belonging to the field of steel plate marking technology. Background Technology

[0002] Various markings are required on the surface of steel plates to ensure accurate and traceable information on the produced plates. Therefore, the normal operation of the online steel plate stamping machine is crucial. When the steel plate thickness is small, the impact of the steel needle on the steel plate during operation can cause the steel plate to vibrate vertically and horizontally. This can result in ghosting, skewing, or garbled characters in the printed text, leading to poor stamped character quality. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a device for enhancing the stability of online steel stamping machines, which effectively prevents the thin steel plate from shaking in the up-down and left-right directions during the steel stamping process, avoids ghosting, skewing or garbled characters in the printed characters, and improves the effect of steel stamping characters.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a device for enhancing the stable operation of an online steel stamping machine, comprising two symmetrically arranged roller support brackets, a conveyor roller between the roller support brackets, a roller cover plate above the conveyor roller, and a gap between the roller cover plate and the conveyor roller, the gap serving as a conveying channel; the two sides of the roller cover plate are fixedly connected to the roller support brackets through cover plate connecting frames; a crossbeam is provided above the roller cover plate, a steel stamping machine is mounted on the bottom surface of the crossbeam, and multiple pressing cylinders are provided on the bottom surface of the crossbeam, the multiple pressing cylinders being evenly spaced along the width of the roller, and the cylinder seats of the pressing cylinders being respectively fixed to the bottom of the crossbeam. On the surface, pressure plates are respectively provided at the ends of the extension rods of the pressure cylinders, and multiple pressure plate channels are opened on the roller cover plate. The pressure plate channels correspond to the pressure plates. The pressure cylinder drives the pressure plates to move downward, and the pressure plates pass through the pressure plate channels to approach and press against the steel plates; or it drives the pressure plates to move upward, and the pressure plates move away from the steel plates and rise above the roller cover plate. Sensors are respectively provided on the cylinder base of the pressure cylinders, and multiple detection holes are also opened on the roller cover plate. The detection holes are located directly below the sensors, and the sensors are signal-connected to the pressure cylinders. The sensors are used to detect whether there are steel plates below the detection holes, and then control whether the corresponding pressure cylinders are activated.

[0005] The dimensions of the pressure plate channel are matched with the dimensions of the pressure plate.

[0006] The diameter of the detection hole is larger than the detection range of the sensor.

[0007] The conveyor roller conveyor includes several parallel conveyor rollers, and the roller shafts of the two conveyor rollers closest to the inlet side of the steel printing machine are respectively connected to the output shaft of the motor with a brake.

[0008] The sensor is a position sensor.

[0009] Compared with the prior art, the advantages of this utility model are: a device for stabilizing the operation of an online steel printing machine, which uses a pressure cylinder to drive a pressure plate to press the steel plate, preventing the thin steel plate from shaking in the vertical direction during the steel printing process, and uses a brake to lock the rotation of the conveyor roller, preventing the thin steel plate from shaking in the horizontal direction during the steel printing process, thus avoiding ghosting, skewing or garbled characters in the printed characters and improving the steel printing effect.

Detailed Implementation

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1As shown, this embodiment of a device for enhancing the stable operation of an online steel stamping machine includes two symmetrically arranged roller support brackets 9. A conveyor roller for conveying steel plates is located between the roller support brackets 9. A roller cover plate 7 is located above the conveyor roller, with a gap between the conveyor roller and the roller cover plate 7 serving as a conveying channel. The roller cover plate 7 protects the conveyor roller and prevents foreign objects from falling into the gap. The roller cover plate 7 is fixedly connected to the roller support brackets 9 on both sides via cover plate connecting frames. A crossbeam 1 is located above the roller cover plate 7. The steel stamping machine 3 is fixed to the bottom surface of the crossbeam 1. Multiple vertically arranged pressing cylinders 2 are located on the bottom surface of the crossbeam 1, evenly spaced along the width of the conveyor roller. The cylinder seats of the pressing cylinders 2 are respectively fixed to the bottom surface of the crossbeam 1, and pressure plates 5 are respectively installed at the ends of the extended rods of the pressing cylinders 2. Multiple pressure plate channels are provided on the roller cover plate 7. These channels correspond to pressure plates 5, and their dimensions are adapted to (or slightly larger than) those of pressure plates 5. When the pressure cylinder 2 drives the pressure plate 5 to move downwards, the pressure plate 5 can pass through the pressure plate channels to approach and press against the steel plate. Alternatively, when the pressure cylinder 2 drives the pressure plate 5 to move upwards, the pressure plate can pass through the pressure plate channels away from the steel plate and rise above the roller cover plate. Position sensors 4 are respectively installed on the cylinder base of the pressure cylinder 2, and are arranged close to the cylinder base of the pressure cylinder 2. Multiple detection holes are also provided on the roller cover plate 7. These detection holes are located directly below the position sensors, and their diameter is slightly larger than the detection range of the position sensors, approximately 5-8 mm larger than the detection range of the position sensors 4, ensuring that the position sensors can accurately identify the presence or absence of steel plates. The position sensors are signal-connected to the corresponding pressure cylinders. The position sensors detect the presence of steel plates through the detection holes, thereby controlling whether the corresponding pressure cylinders operate. When the position sensor detects a steel plate passing by through the detection hole, the corresponding pressure cylinder drives the pressure plate to approach and press against the surface of the steel plate through the pressure plate channel to prevent the steel plate from shaking up and down.

[0013] The first pressure cylinder corresponds to the reference edge of the steel plate, ensuring that the reference edge of the steel plate is pressed tightly.

[0014] The position sensor detects steel plates of different widths and controls the corresponding pressure plates accordingly to prevent the pressure plates from pressing down on the conveyor rollers and causing damage.

[0015] The conveyor roller conveyor includes several parallel conveyor rollers 8. The roller shafts of the two conveyor rollers 8 closest to the inlet side of the steel printing machine are respectively connected to the output shaft of the motor 6 with a brake. When the steel printing machine is working, the brake locks the rotation of the corresponding conveyor roller, indirectly increasing the frictional resistance between the steel plate and the surface of the conveyor roller, preventing the steel plate from moving left and right (preventing the steel plate from shaking along the axial direction of the conveyor roller).

[0016] This application uses a pressure cylinder to drive a pressure plate to press the steel plate, preventing the thin steel plate from shaking vertically during the steel printing process. It also uses a brake to lock the rotation of the conveyor roller, preventing the thin steel plate from shaking horizontally during the steel printing process. This avoids ghosting, skewing, or garbled characters in the printed text, thus improving the quality of the steel-printed characters.

[0017] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
