[0002] The tape used in the film-peeling machine is a consumable and needs to be replaced regularly. Different production batches or processes may require the use of different specifications and models of tape.

[0003] Existing film-tearing machines have relatively simple film roller mechanisms, typically only performing unwinding. This necessitates manual verification and setting of equipment parameters when changing tape, presenting a cumbersome and error-prone operation.

[0004] Meanwhile, existing equipment often fails to detect and alarm when new film rolls stop rotating due to jamming or breakage, which may lead to film tearing failure or equipment idling, affecting production efficiency and yield. Utility Model Content

Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0023] This application discloses a new film sleeve installation device for an adhesive film peeling machine.

[0024] A new film sleeve mounting device for an adhesive film peeling machine includes a new film wheel mechanism 1, a sensing component, and a mounting bracket 4. The new film wheel mechanism 1 consists of a new film roller 11 and an adaptive clamping plate 12. The new film roller 11 is rotatably mounted on the mounting bracket 4 to support a new film roll 6. The adaptive clamping plate 12 is pressed onto the new film roller 11 by spring screws, adapting to film rolls 6 of different widths or inner diameters. The sensing component integrates a magnetic induction unit 2 and a consumable identification unit, used to monitor the rotation status of the new film wheel and automatically identify consumable specifications, respectively.

[0025] The adaptive clamping plate 12 achieves compatibility and fixation of film rolls 6 with different physical specifications through elastic pressure. The magnetic induction unit 2 monitors whether the unwinding is normal by detecting the periodic magnetic signal changes of the rotating component. The consumable identification unit reads the specification information pre-stored in the consumable chip non-contactly through wireless radio frequency communication, realizing intelligent identification that can be used immediately after installation.

[0026] Adaptive clamping plates 12 are disposed on the outer wall of the new diaphragm wheel mechanism 1. Multiple sets of adaptive clamping plates 12 are disposed circumferentially along the outer wall of the new diaphragm wheel mechanism 1. Each circumferential set contains multiple adaptive clamping plates 12 distributed along the axial direction of the new diaphragm wheel mechanism 1, thereby forming a matrix clamping network covering its working area on the roller surface.

[0027] When an operator inserts a new membrane roll 6 into the new membrane roller mechanism 1, the inner wall of the membrane roll 6 simultaneously contacts multiple adaptive clamping plates 12 distributed circumferentially and axially. During the insertion process, each clamping plate independently retracts or extends slightly radially according to the local contour of the inner wall it contacts, and maintains a constant clamping force through a spring mechanism on its back. Ultimately, all clamping plates work together to determine and support the optimal center position of the membrane roll 6, ensuring that it maintains a high degree of coaxiality with the new membrane roller 11.

[0028] Multiple placement platforms 14 are provided on the outer wall of the new membrane wheel mechanism 1. The adaptive clamping plate 12 is correspondingly installed on these placement platforms 14, and precise positioning and reliable support are achieved through the reference mounting surface provided by the placement platform 14.

[0029] During assembly, the adaptive clamping pad 12 and its underlying elastic element, such as a spring, are fixed to the placement platform 14. When the membrane roll 6 is loaded, each adaptive clamping pad 12, supported and guided by its corresponding placement platform 14, independently performs adaptive micro-motion in the radial direction. Throughout the process, the placement platform 14 acts as a robust base, ensuring that the adaptive clamping pad 12 does not undergo unexpected deflection or twisting, thus keeping its clamping action stable and controllable.

[0030] The adaptive clamping plate 12 specifically adopts a butterfly clamp spring structure. This butterfly clamp spring is installed on the placement platform 14 through its unique double-wing elastic structure, providing a balanced radial clamping force for the inner core of the membrane roll 6.

[0031] During the installation of membrane roll 6, the inner hole of membrane roll 6 contacts the protruding part of the butterfly clamp spring and applies radial pressure, forcing the spring to undergo elastic deformation. As membrane roll 6 advances, multiple circumferentially arranged butterfly clamp springs deform synchronously, each clamping the inner wall of membrane roll 6 with its independent elastic force. During unwinding, even if the diameter of membrane roll 6 gradually decreases, the butterfly clamp springs can maintain a stable clamping state through continuous elastic restoring force, preventing slippage.

[0032] The magnetic induction unit 2 includes a first baffle 21, a magnet 22, and a magnetic sensor 23. The first baffle 21 is mounted on the new film roller mechanism 1 and rotates synchronously with the new film roller 11. The magnet 22 is fixedly mounted on the first baffle 21 and rotates with it. The magnetic sensor 23 is fixedly mounted on the mounting bracket 4, with its detection end aligned with the movement trajectory of the magnet 22. When the first baffle 21 drives the magnet 22 to rotate, the magnetic sensor 23 senses the rotation state by detecting the periodic changes in the magnetic field strength.

[0033] The rotational motion of magnet 22 along with the first baffle 21 is converted into a periodic magnetic field change, which is captured by a fixed magnetic sensor 23 and converted into a corresponding pulse electrical signal. By monitoring the frequency and continuity of this pulse signal, it is possible to determine in real time whether the rotation of the new diaphragm wheel is normal.

[0034] During the normal unwinding process of the new film roller, the new film roller 11 drives the first baffle 21 and the magnet 22 to rotate at a constant speed. Whenever the magnet 22 passes through the detection area of ​​the magnetic sensor 23, the sensor outputs an electrical pulse signal. The control system can monitor the unwinding speed in real time by continuously monitoring the frequency of this pulse signal; if no pulse signal is detected within a certain period of time or the frequency drops abnormally, it is immediately determined that the new film roller has a fault such as jamming, stopping, or tape breakage.

[0035] The consumable identification unit includes an RFID sensing antenna and a PCB board 3. The RFID sensing antenna is fixedly mounted on the mounting bracket 4, with its sensing area facing the installation position of the new film roll 6, for non-contact reading of the specification information stored in the RFID chip embedded in the new film roll 6.

[0036] When the new film roll 6 with the RFID chip is installed in the working position and enters the reading range of the RFID sensing antenna, the antenna activates the chip by transmitting a radio frequency signal and receives the stored data fed back by the chip. This data is transmitted via lines to the PCB board 3 for decoding processing, and finally the identified consumable specification information is transmitted to the equipment's main control system.

[0037] After the operator replaces the film roll 6 with a new one and installs it in place, the equipment powers on or receives a roll change completion signal. At this time, the RFID sensing antenna automatically starts the reading process, scanning and acquiring key parameters such as model, batch, and length pre-stored in the RFID chip. The acquired data is processed by the PCB board 3 and automatically loaded into the equipment control system, completing a seamless switch of production parameters. If the reading fails or an unauthorized consumable is identified, the system will issue an alarm and pause the startup.

[0038] The membrane roll mechanism also includes a second baffle 13, which is coaxially mounted on the first baffle 21 and rotates with the first baffle 21 to protect the first baffle 21. At the same time, an RFID sensing antenna is mounted on the second baffle 13 to facilitate reading the RFID chip on the membrane roll 6.

[0039] The new film sleeve mounting device also includes a flip-top plate 5, which is detachably mounted on the frame 7 of the film tearing machine via a hinge or quick-release mechanism. The mounting bracket 4 and the entire new film roller mechanism 1 it supports are located on top of the flip-top plate 5. Furthermore, the flip-top plate 5 is specially equipped with a cable routing groove 51 for laying various cables connected to the new film roller mechanism 1. When changing the film roll 6 or performing equipment maintenance, the operator opens the flip-top plate 5 to facilitate cable maintenance.

[0040] The implementation principle of the new film sleeve installation device for an adhesive film peeling machine according to an embodiment of this application is as follows: When installing a new film roll 6, the new film roll 6 with an RFID chip attached is sleeved onto the new film roller mechanism 1. The inner wall of the film roll 6 simultaneously presses the butterfly clips distributed in a matrix in the circumferential and axial directions. Under the precise guidance of the placement platform 14, each butterfly clip independently moves radially and continuously outputs elastic restoring force, which together automatically centers the film roll 6 and holds it tightly to the new film roller 11 with high coaxiality. The radio frequency signal of the RFID sensing antenna activates the RFID chip in the film roll 6. The model, batch, length and other specification information read are automatically loaded into the main control system after being decoded by the PCB board 3 to complete the parameter switching. If the reading fails or the consumable is not authorized, the system alarms and stops.

[0041] After the equipment is started, the new film roller 11 unwinds and drives the first baffle 21 and its magnet 22 to rotate at a constant speed. The fixed magnetic sensor 23 converts the periodic magnetic field changes into pulse electrical signals. The control system monitors the pulse frequency to keep track of the unwinding speed in real time and immediately determines the fault and stops the machine when there is jamming, stopping, or tape breakage. The second baffle 13 rotates synchronously to protect the magnetic induction unit 2. When it is necessary to repair the cable, the flip cover 5 can be opened.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
