Description

Technical Field

[0001] This utility model relates to the field of reflective film roll installation and allowance detection technology, specifically, to a reflective film processing allowance detection device. Background Technology

[0002] Currently, in the production process of semi-finished license plates, a reflective film is applied to their surface. This film reflects light off the license plate, ensuring that the information is clearly visible even in low-light conditions. This design guarantees that drivers can clearly identify the license plate number in both sunlight and darkness, thereby enhancing driving safety.

[0003] Currently, the reflective film roll needs to be connected to the driving equipment, which then drives the reflective film roll to rotate at a constant speed. Then, one end of the reflective film is connected to the laminating equipment, and subsequent processing can begin. However, the existing connection and disassembly process between the driving equipment and the reflective film roll is cumbersome and inconvenient. At the same time, it is impossible to detect the remaining amount of reflective film in real time, which leads to the problem of the reflective film running out but not being replaced in time. The connection between the reflective film roll and the driving equipment, as well as the real-time remaining amount detection process of the reflective film roll, need to be optimized. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a device for detecting the processing allowance of reflective film.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A device for detecting processing allowance of reflective film includes a drive unit, a frame, a laser displacement sensor, a first telescopic cylinder, a support plate, an arc groove, a connecting roller, an electromagnetic clutch, a mounting platform, a translation and pushing assembly, and an alarm.

[0007] The laser displacement sensor, the two first telescopic cylinders, and the mounting platform are all fixed on the frame, and the laser displacement sensor is electrically connected to the drive equipment.

[0008] The support plate is connected to a first telescopic cylinder that corresponds to it, and the support plate is provided with an arc groove.

[0009] The connecting roller is fixedly connected to the reflective film roll;

[0010] The electromagnetic clutch is connected to a drive device and cooperates with the connecting roller;

[0011] The translation and pushing components and the alarm are both mounted on the mounting platform, and the alarm is electrically connected to the laser displacement sensor.

[0012] Furthermore, the translational pushing component includes a second telescopic cylinder and a push plate. The second telescopic cylinder is provided on the mounting platform, and the push plate is connected to the second telescopic cylinder.

[0013] The above solution can automatically lock one end of the connecting roller with the electromagnetic clutch by using the translation and pushing component in conjunction with the support plate and the arc groove, thereby completing the quick connection between the reflective film roll and the driving equipment.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Compared to existing technologies, this device only requires placing the two ends of the connecting roller into the arc grooves of the two support plates. It can then automatically complete the docking and locking between the reflective film roll and the drive equipment. After locking, the end of the reflective film is connected to the laminating equipment, which can then drive it to rotate at a uniform speed for use. The installation process is effectively simplified. At the same time, unloading the reflective film after use is convenient. Simply disconnect the reflective film from the paper tube and then control the electromagnetic clutch to cut off the power. Meanwhile, the remaining amount of the reflective film roll can be detected in real time during use, thus avoiding the problem of the reflective film running out without timely replacement. The remaining amount detection is accurate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0022] like Figure 1 and Figure 2As shown, a reflective film processing allowance detection device includes a drive unit 6, a frame 1, a laser displacement sensor 2, a first telescopic cylinder 3, a support plate 4, an arc groove 41, a connecting roller 5, an electromagnetic clutch 7, a mounting platform 8, a translation and pushing assembly, and an alarm 11.

[0023] The laser displacement sensor 2, the two first telescopic cylinders 3, and the mounting platform 8 are all fixed on the frame 1, and the laser displacement sensor 2 is electrically connected to the drive device 6.

[0024] The support plate 4 is connected to a first telescopic cylinder 3 that corresponds to it, and the support plate 4 is provided with an arc groove 41.

[0025] Connecting roller 5 is fixedly connected to the reflective film roll;

[0026] The electromagnetic clutch 7 is connected to the drive device 6 and cooperates with the connecting roller 5;

[0027] The translation and pushing component and the alarm 11 are both mounted on the mounting platform 8, and the alarm 11 is electrically connected to the laser displacement sensor 2.

[0028] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the translation and pushing component includes a second telescopic cylinder 9 and a push plate 10. The second telescopic cylinder 9 is provided on the mounting platform 8, and the second telescopic cylinder 9 is connected to the push plate 10.

[0029] It should be noted that the laser displacement sensor 2, the first telescopic cylinder 3, the electromagnetic clutch 7, the second telescopic cylinder 9, and the alarm 11 are all electrically connected to the controller, which is not shown in the figure.

[0030] The working process of this utility model is as follows:

[0031] A connecting roller 5 is pre-fixed in the center hole of the paper tube of each reflective film roll, with both ends of the connecting roller 5 extending to the outside of the reflective film roll and having equal lengths. Then, when the reflective film roll needs to be installed, simply place the connecting roller 5 into the arc groove 41 of the two support plates 4 (the arc groove 41 fits against the surface of the connecting roller 5, and the initial position of the support plates 4 is pre-set, as shown in the instruction manual). Figure 1As shown in the diagram, after the connecting roller 5 is placed, the center of the reflective film roll and the center of the push plate 10 are on the same straight line. Then the controller controls the second telescopic cylinder 9 to work and drive the push plate 10 to move horizontally. When the push plate 10 contacts the connecting roller 5, the reflective film roll can be adjusted horizontally to the left (after the adjustment is completed, the left end face of the reflective film roll is not in contact with the left support plate 4 and the left end face of the connecting roller 5 enters the electromagnetic clutch 7). After the movement is completed, the controller controls the electromagnetic clutch 7 to work and lock one end of the connecting roller 5. After locking, the reflective film is first connected to the laminating equipment. Then the controller controls the two first telescopic cylinders 3 to retract synchronously and the connecting roller 5 is disengaged from the arc groove 41. Finally, the controller controls the drive equipment 6 to work and the reflective film roll can be rotated at a uniform speed and then the subsequent processing can begin.

[0032] The initial distance between the laser displacement sensor 2 and the outermost edge of the reflective film roll is determined (the number of turns of several reflective film rolls is the same). As the reflective film is used, the distance between the laser displacement sensor 2 and the outermost reflective film will gradually increase. When the distance between the two is about to reach the upper limit value set in the controller, the laser displacement sensor 2 immediately sends a signal to the controller. The controller then controls the drive device 6 and the laminating device to stop working at the same time. At this time, there is a margin at the end of the reflective film roll and the alarm 11 sounds an alarm. When the reflective film end is manually disconnected from the paper tube, the paper tube is held by hand and the electromagnetic clutch 7 is de-energized by the controller to realize the transfer and unloading of the paper tube. After the unloading is completed, the controller controls the first telescopic cylinder 3 to drive the support plate 4 to move back to the initial position, and the replacement and installation process of the new reflective film roll can begin. After the new reflective film is loaded, it is connected with the previous section of reflective film with a margin and can be put into use again.

[0033] Compared to existing technologies, this device only requires placing the two ends of the connecting roller 5 into the arc grooves 41 of the two support plates 4, and then it can automatically complete the docking and locking between the reflective film roll and the drive device 6. After locking, the end of the reflective film is connected to the laminating device, and it can be driven to rotate at a uniform speed for use. The installation process is effectively simplified. At the same time, the unloading of the reflective film is convenient after use. Just disconnect the reflective film from the paper tube and then control the electromagnetic clutch 7 to cut off the power. Meanwhile, the remaining amount of the reflective film roll can be detected in real time during use, so as to avoid the problem of the reflective film running out but not being replaced in time. The remaining amount detection is accurate.

[0034] In other embodiments, such as Figure 3As shown, a visual inspection component 12 is installed on the mounting platform 8, and the visual inspection component 12 is electrically connected to the alarm 11 and the drive device 6 respectively. In this embodiment, the visual inspection component 12 can play a dual auxiliary role in detecting the remaining amount of reflective film. If the laser displacement sensor 2 malfunctions, the visual inspection component 12 can also effectively detect the change in the remaining amount of reflective film (the minimum thickness of the reflective film end face is transmitted in advance in the controller). During use, the end face thickness of the reflective film roll is photographed in real time and the images are compared. When the image comparison is basically consistent, a signal can be fed back to the controller to stop the drive device 6 and the laminating device, and the alarm 11 will sound an alarm to prompt the replacement of the reflective film roll.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
