Description

Technical Field

[0001] This application relates to the field of adhesive film peeling machine technology, and in particular to a waste film sleeve installation device for an adhesive film peeling machine. Background Technology

[0002] In adhesive tape tearing machines, tape with waste film adhering to it is recycled onto a waste film roller. In existing technology, waste film is usually directly wound onto a fixed waste film roller. When the waste film roll is full, the entire roll of waste film needs to be removed from the roller, which is often inconvenient and can easily cause the waste film to scatter during disassembly, affecting the working environment.

[0003] Currently, there is a lack of a dedicated device that can conveniently and quickly collect and remove waste film. Directly removing waste film from the roller that is fixed to the drive mechanism is not only time-consuming and labor-intensive, but may also damage the roller surface or affect the accuracy of the drive mechanism. Utility Model Content

The drive mechanism is connected to the waste film roller and is used to drive the waste film roller to rotate.

[0006] Optionally, the drive mechanism includes a drive motor, a synchronous pulley, and a synchronous belt, wherein: The drive motor drives the waste film roller via a synchronous belt and a synchronous pulley.

[0007] Optionally, the waste film sleeve installation device further includes a protective cover plate, which covers the outside of the waste film roller for safety protection.

[0008] Optionally, the waste film sleeve installation device further includes a rotation sensing component, which includes a toothed plate disposed on the waste film roller and an optical coupler sensor disposed on the frame, for monitoring the rotation status of the waste film roller.

[0009] Optionally, the waste film roller is fixed to the frame by bearings and bearing mounting sleeves to ensure smooth rotation.

[0010] Optionally, the disposable waste film sleeve has a limiting groove on its cylinder wall, and the limiting groove has an opening that penetrates the end of the disposable waste film sleeve. The positioning pin is located on the waste film roller, penetrates the limiting groove, and slides in cooperation with the limiting groove.

[0011] Optionally, the limiting groove and the opening are configured as a T-shaped groove.

[0012] Optionally, multiple limiting grooves are provided circumferentially along the axis of the disposable waste film sleeve, and the waste film roller is provided with multiple positioning pins that are adapted to the limiting grooves.

[0020] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0021] This application discloses a waste film sleeve installation device for an adhesive film peeling machine.

[0022] A waste film sleeve mounting device for an adhesive film tearing machine includes a waste film roller 1, a disposable waste film sleeve 2, and a drive mechanism 3. The waste film roller 1 is rotatably mounted on the frame 8 of the film tearing machine via a bearing assembly 6. The disposable waste film sleeve 2 is detachably sleeved on the outside of the waste film roller 1, and the two are fastened together by a positioning pin 11, allowing the sleeve to rotate synchronously with the roller. The drive mechanism 3 is driven by the waste film roller 1 and provides the power for rotation and winding.

[0023] The positioning pin 11 enables rapid positioning and power transmission between the disposable waste film sleeve 2 and the waste film roller 1, making them two independent units. During operation, the drive mechanism 3 drives the waste film roller 1 to rotate, and the disposable waste film sleeve 2 is driven to rotate along with it via the positioning pin 11, tightly winding the adhesive tape 7 with the waste film attached to its surface. When the waste film is wound to the predetermined capacity, the drive stops. The operator only needs to disengage the disposable waste film sleeve 2 from the positioning pin 11 to remove the fully loaded disposable waste film sleeve 2 from the waste film roller 1. Subsequently, an empty disposable waste film sleeve 2 is put back onto the roller and aligned with the positioning pin 11 to quickly complete the replacement and restore equipment operation.

[0024] The drive mechanism 3 specifically includes a drive motor 31, a synchronous pulley 32, and a synchronous belt 33. The output shaft of the drive motor 31 is connected to a synchronous pulley 32, and transmits power to another synchronous pulley 32, which is coaxially mounted with the waste film roller 1, through the synchronous belt 33, thereby precisely and smoothly driving the waste film roller 1 to rotate.

[0025] The toothed grooves of the synchronous belt 33 and the synchronous pulley 32 mesh with each other, effectively eliminating the slippage phenomenon present in traditional friction transmission, ensuring a strict synchronization relationship between the rotation angle of the motor and the rotation angle of the waste film roller 1, thereby providing precise control for the winding speed of the tape 7.

[0026] After the equipment operation command is issued, the drive motor 31 starts, driving the synchronous pulley 32 on its output shaft to rotate. The rotational power is instantly transmitted to the synchronous pulley 32 at the shaft end of the waste film roller 1 through the tensioned synchronous belt 33, thereby driving the entire waste film roller 1 and the disposable waste film sleeve 2 fitted on it to rotate synchronously. In this process, the adhesive tape 7 with waste film adhering to it is continuously and smoothly wound around the surface of the sleeve. There is no slippage in the entire transmission process, and the speed is constant.

[0027] The waste film sleeve installation device also includes a protective cover plate 4, which is installed on the axial end of the waste film roller 1 to axially limit the disposable waste film sleeve 2 sleeved on the roller and prevent it from accidentally detaching from the end of the waste film roller 1 during operation.

[0028] By installing a protective cover plate 4 at a fixed position adjacent to the end of the waste film roller 1, its inner surface forms a physical blocking surface. When the disposable waste film sleeve 2 rotates at high speed or is pulled axially by the tension of the tape 7, its end face will be reliably blocked by the protective cover plate 4, thus being restricted to the preset axial working position and unable to move or fall off.

[0029] When installing the disposable waste film sleeve 2, first put the empty disposable waste film sleeve 2 onto the waste film roller 1 and align and fasten it with the positioning pin 11. Then, align the protective cover plate 4 with the installation position and fix it in place using screws, clips, or other means.

[0030] When the waste film sleeve needs to be replaced, the protective cover plate 4 must be removed first before the fully loaded sleeve can be taken off. After replacing the sleeve with a new one, the protective cover plate 4 must be reinstalled. The equipment's safety interlock system can be designed to allow operation only after the protective cover plate 4 is detected in place.

[0031] The waste film sleeve installation device also integrates a rotation sensing component 5, which consists of a toothed plate 51 and an optical coupler sensor 52. The toothed plate 51 is fixedly installed at the end of the waste film roller 1 and rotates synchronously with it, while the optical coupler sensor 52 is fixed on the frame 8 corresponding to the rotation trajectory of the toothed plate 51. The two work together to monitor the rotation status of the waste film roller in real time.

[0032] As the teeth of the rotating toothed disc 51 pass sequentially through the detection slot of the optocoupler sensor 52, they create a periodic pass-block-pass effect on the sensor's infrared light path. This periodic change in the light path is converted by the optocoupler sensor 52 into a series of regular pulse electrical signals. By monitoring the frequency or presence of these pulse signals, the real-time rotational speed and state of the waste film roller can be accurately determined.

[0033] During the winding operation, the waste film roller 1 drives the toothed plate 51 to rotate at a constant speed. The optocoupler sensor 52 continuously detects and outputs a high-frequency pulse signal to the control system, indicating normal winding operation. If the waste film roller experiences an abnormally low speed or stops completely due to a jammed belt 7, transmission failure, or motor malfunction, the pulse frequency output by the optocoupler sensor 52 will significantly decrease or return to zero. By monitoring this signal change in real time, the control system can immediately identify this abnormal state. The bearing assembly 6 includes a bearing 61 and a bearing mounting sleeve 62. The shaft of the waste film roller 1 is supported by the bearing 61, which is mounted in the bearing mounting sleeve 62, ultimately securing the entire rotating assembly to the frame 8.

[0034] During equipment assembly, the bearing 61 is first pressed into or embedded in the inner hole of the bearing mounting sleeve 62, and then this assembly is installed as a whole unit in the preset position of the frame 8 and fixed. Finally, the shaft of the waste film roller 1 is passed through and fixed to the inner ring of the bearing 61.

[0035] A limiting groove 22 is provided on the wall of the disposable waste film sleeve 2. One end of the limiting groove 22 has an opening 21, which penetrates the end edge of the sleeve, so that the limiting groove 22 and the opening 21 together form a T-shaped groove 23 structure. Correspondingly, a positioning pin 11 is fixedly mounted on the waste film roller 1. During installation, the positioning pin 11 first enters through the opening 21, then slides into and penetrates the limiting groove 22, thereby realizing a sliding fit between the positioning pin 11 and the limiting groove 22.

[0036] During installation, the operator aligns the opening 21 of the T-slot 23 on the sleeve with the positioning pin 11 on the waste film roller 1 and inserts it radially. Then, the sleeve is pushed axially, causing the positioning pin 11 to slide from the opening 21 into the limiting groove 22. At this point, rotating the waste film roller 1 causes the positioning pin 11 to immediately contact the side wall of the limiting groove 22, thereby causing the disposable waste film sleeve 2 to rotate synchronously. For disassembly, the operation is reversed: first, the sleeve is pushed axially to allow the positioning pin 11 to slide back to the position corresponding to the opening 21, then the sleeve can be removed radially.

[0037] On the disposable waste film sleeve 2, multiple T-shaped grooves 23 can be uniformly or symmetrically arranged along its circumference. Correspondingly, on the waste film roller 1, multiple positioning pins 11 are also provided in number and position that are completely corresponding to them. Each positioning pin 11 forms a sliding fit relationship with a corresponding T-shaped groove 23 as described above.

[0038] By using multiple circumferentially distributed T-grooves 23 and locating pins 11, the driving torque and load are distributed to multiple points, thereby improving the balance of power transmission and the centering accuracy of sleeve installation.

[0039] The implementation principle of the waste film sleeve installation device for an adhesive film tearing machine according to an embodiment of this application is as follows: When the adhesive film tearing machine is running, the drive motor 31 transmits power to the waste film roller 1 supported by the bearing assembly 6 without slippage via the synchronous pulley 32 and synchronous belt 33. A number of positioning pins 11 distributed circumferentially on the roller are aligned with the corresponding number of T-shaped limiting grooves 22 openings 21 on the cylinder wall of the disposable waste film sleeve 2, slide in, and are axially pushed tight, so that the disposable waste film sleeve 2 and the waste film roller 1 are fastened together. The protective cover plate 4 is locked at the shaft end to prevent the disposable waste film sleeve from being used. When the membrane sleeve 2 detaches, the toothed blade 51 continuously cuts the optical path output pulse of the optical coupler sensor 52 as the drum rotates. The control system monitors the rotation speed in real time based on this. The waste film roller 1 drives the sleeve to uniformly wind up the tape 7 with waste film until the predetermined capacity is reached. Then, the machine is stopped. First, the protective cover plate 4 is removed, and then the disposable waste film sleeve 2 is pushed axially to make the positioning pin 11 return to the opening 21 of the T-slot 23. The fully loaded disposable waste film sleeve 2 is removed radially, replaced with an empty disposable waste film sleeve 2, and the positioning pin 11 is re-fastened. The protective cover plate 4 is then installed back, and the equipment resumes operation.

[0040] 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.
