Description

Technical Field

[0001] This utility model relates to the field of light-sensitive feeding machine technology, specifically a light-sensitive feeding machine. Background Technology

[0002] In existing technological systems, a typical processing scenario exists: roller coaters are used in the screen printing process of metal strips. Specifically, the roller coater precisely completes the screen printing operation on a continuous metal strip, and then the screen-printed metal strip is separated to obtain small, individually formed metal nameplates. These metal nameplates have a wide range of uses; for example, they can be riveted to the surface of machinery and equipment to clearly mark key parameters such as rated voltage and current; they can also be installed on various other products as needed.

[0003] In this processing flow, the unloading device plays an indispensable role in ensuring the smooth entry of the metal strip into the corresponding processing equipment for subsequent processing. When a roll of steel strip needs to be processed, the unloading device can stably and orderly unfold and release the steel strip, ensuring that the steel strip is continuously conveyed with appropriate tension and speed, thereby guaranteeing the continuity and efficiency of the entire processing process.

[0004] In order to ensure that the steel strip is continuously conveyed with appropriate tension and speed, such feeding devices in the existing technology generally need to be matched with tension sensors. However, tension sensors generally require mechanical contact or direct contact when in use: the sensor needs to be embedded in the tension roller or guide roller of the feeding machine, and the steel strip / film directly presses the elastomer (such as an S-type tension sensor).

[0005] Indirect contact: The tension is transmitted to the sensor (such as a pressure sensor to measure the pressure of the material roll on the roller shaft) through a pulley block or lever mechanism. This is more troublesome when these tension control systems need to be installed temporarily. At the same time, due to the contact, additional friction loss will be generated. Therefore, an improved optical feeding machine is needed to address this problem. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a photosensitive feeding machine, including a fixed base 1, a feeding machine 2 is provided on the upper end of the fixed base 1, a tensioning device 3 is movably provided on one side of the upper end of the feeding machine 2 via a rotating shaft, a steel coil 4 is sleeved on the outside of the tensioning device 3, a first motor 5 is fixedly provided on the side of the feeding machine 2 away from the tensioning device 3, and a detection mechanism for detecting the tightness of feeding is provided on one side of the fixed base 1. The detection mechanism includes a fixed frame 6, a movable plate 7, a mounting base 8, a movable ball 9, and a photosensitive probe 10. The fixed frame 6 is provided on one side of the fixed base 1, the movable plate 7 is movably sleeved on the outer surface of the fixed frame 6, the mounting base 8 is fixedly provided on the upper end of the movable plate 7, the movable ball 9 is movably engaged inside the mounting base 8, and the photosensitive probe 10 is fixedly provided on the surface of the movable ball 9.

[0023] A feeding mechanism is provided on one side of the fixed frame 6. The feeding mechanism includes a feeding frame 11, a feeding roller 12, and a second motor 13. The feeding frame 11 is provided on one side of the fixed frame 6. The feeding roller 12 is movably mounted on the upper end of the feeding frame 11 via a rotating shaft. The second motor 13 is fixedly mounted on one side of the feeding frame 11. The power output shaft of the second motor 13 is connected to the feeding roller 12. The second motor 13 can drive the feeding roller 12 to rotate, thereby conveying the steel strip released by the first motor 5 and the unloading machine 2 towards the processing equipment.

[0024] A control box 14 is mounted on the surface of the feeding frame 11. The signal input terminal of the control box 14 is electrically connected to the signal output terminal of the photosensitive probe 10. The control signal output terminal of the control box 14 is also electrically connected to the control signal input terminals of the first motor 5 and the second motor 13. The infrared laser ranging device of the photosensitive probe 10 in this device is specifically as follows... Figure 2 As shown, the height of the steel strip from the photosensitive probe 10 can be monitored in real time. Since the rotation speed of the second motor 13 is constant, the conveying speed of the steel strip into the processing equipment is kept constant. However, as the first motor 5 drives the tensioning device 3 to rotate, the steel coil 4 is unloaded. Gradually, the diameter of the steel coil 4 will decrease. If the first motor 5 continues to unload at the predetermined speed, the steel strip will be gradually tensioned, thus making the distance between the steel strip and the photosensitive probe 10 farther and farther. When the distance of the steel strip exceeds the threshold, the control box 14 receives an electrical signal and then increases the rotation speed of the first motor 5 accordingly, thus achieving the effect of balancing unloading and feeding. This controls the rotation speed of the first motor 5 and the second motor 13 to ensure that the material is always in a relatively suitable relaxation range. At the same time, the detection device of this device does not need to contact the material and is easy to install, thus facilitating its widespread use.

[0025] A compression screw 15 is provided on one side of the surface of the mounting base 8 by means of a threaded engagement. Tightening the compression screw 15 can compress and fix the angle of the photosensitive probe 10.

[0026] A screw 16 is fixedly installed at the lower middle of the movable plate 7, and a threaded sleeve 17 is movably installed at the lower middle of the fixed frame 6 through a bearing. The threaded sleeve 17 is movably sleeved on the outer surface of the screw 16 through a thread. By rotating the threaded sleeve 17 in conjunction with the thread, the movable plate 7 can be driven to move up and down, thereby adjusting the height of the photosensitive probe 10.

[0027] A rotating block 18 is fixedly provided on the outside of the threaded sleeve 17, which allows the threaded sleeve 17 to be rotated easily; thereby adjusting the height of the movable plate 7 and the photosensitive probe 10.

[0028] Working Principle: The feeding control principle of this device is as follows: the height of the steel strip from the photosensitive probe 10 can be monitored in real time. Since the speed of the second motor 13 is constant, the conveying speed of the steel strip into the processing equipment is kept constant. However, as the first motor 5 drives the tensioning device 3 to rotate, the steel coil 4 is fed out. Gradually, the diameter of the steel coil 4 will decrease. If the first motor 5 continues to feed at the predetermined speed, the steel strip will be gradually tensioned, thus making the distance between the steel strip and the photosensitive probe 10 farther and farther. When the distance of the steel strip exceeds the threshold, the control box 14 receives an electrical signal and then increases the speed of the first motor 5 accordingly, so that the height of the steel strip returns to the threshold range, thus achieving the effect of feeding and feeding balance. This controls the speed of the first motor 5 and the second motor 13 to ensure that the material is always in a relatively suitable relaxation range. At the same time, the detection device of this device does not need to contact the material and is easy to install, thus facilitating its widespread use.

[0029] Meanwhile, when using this device, the height of the photosensitive probe 10 can be adjusted by rotating the threaded sleeve 17, and the angle of the photosensitive probe 10 can be adjusted by rotating the movable ball 9. After adjustment, it can be tightened and fixed by tightening the compression screw 15. In this way, this device can be adapted to be used with feeding machines 2 of various heights as needed, thereby improving the applicability of this device.
