Description

Technical Field

[0001] This utility model relates to the field of automatic line marking technology, and more specifically to an automatic line marking device for film material slitting. Background Technology

[0002] Automatic marking and marking devices offer significant advantages in the film slitting field. Their core benefit lies in dramatically improving slitting accuracy and efficiency. By automating visual positioning and marking, they completely replace traditional methods relying on manual measurement and marking, eliminating inherent defects such as human visual errors, hand tremors, and slow operation. This ensures that each cutting line is highly accurate and consistent, significantly reducing material waste and rework caused by marking errors. The device can be seamlessly integrated into high-speed slitting lines, enabling continuous operation and significantly improving overall equipment efficiency. It is particularly suitable for ultra-thin, high-value, or optically demanding film materials. Its non-contact marking process avoids damage to the material surface, ensuring product integrity.

[0003] Insufficiency of existing technology: Existing technology mainly relies on manual positioning and marking using rulers and pens, which has obvious limitations. Manual operation is easily affected by fatigue and individual skill differences, resulting in poor repeatability and low consistency of marking positions. The manual process is time-consuming and labor-intensive, which cannot match the pace of high-speed slitting equipment, forming a production bottleneck. In poor lighting conditions or when fine marking is required, the accuracy of human eye recognition is insufficient, and it is highly dependent on operator experience, resulting in high training costs and difficulty in achieving standardized operations. Overall, it restricts slitting quality, material utilization rate and capacity improvement. Utility Model Content

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatic marking device for film material slitting involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1 to 3 As shown, this utility model provides an automatic marking device for film material cutting, including a conveyor belt 1, and further including: a photoelectric sensor 2 and an automatic marking module 3. The photoelectric sensor 2 is fixedly installed on the upper side of the conveyor belt 1, and the automatic marking module 3 is fixedly installed on the right side of the photoelectric sensor 2.

[0021] Among them, combined Figure 2 As shown, the photoelectric sensor 2 includes a sensor body 201. Two infrared devices 203 are symmetrically installed on the inner side of the sensor body 201, which is beneficial for real-time detection of the position and movement speed of the membrane material, providing dynamic data for line drawing. An indicator light 202 is fixedly installed on the upper center of the sensor body 201, which can more intuitively display the working status of the sensor and facilitate quick troubleshooting. A wire 205 is fixedly installed on the right side of the sensor body 201, and a signal conversion device 204 is fixedly installed on the lower side of the wire 205. By converting the optical signal into an electrical signal, the system response speed and accuracy can be improved.

[0022] Reference Figures 1 to 3As shown, this utility model provides an automatic marking device for membrane material cutting. Its core lies in combining a conveyor belt 1, a photoelectric sensor 2, and an automatic marking module 3 to achieve automated marking of membrane material cutting. The membrane material is placed on the conveyor belt 1 and moves with the movement of the conveyor belt. The photoelectric sensor 2 is the core component of the device. Two infrared devices 203 symmetrically installed inside the sensor body 201 can detect the position and moving speed of the membrane material in real time. These two infrared devices emit and receive infrared rays. When the membrane material blocks the infrared rays, the sensor can capture the presence of the membrane material and its movement state. These data are transmitted in real time to the control unit of the automatic marking module 3 to provide dynamic data support for the marking operation.

[0023] An indicator light 202, fixedly mounted on the upper center of the sensor body 201, can visually display the sensor's operating status. When the sensor is working normally, the indicator light illuminates; if a malfunction occurs, the indicator light will turn off or flash, facilitating quick troubleshooting. A wire 205, fixedly mounted on the right side of the sensor body 201, transmits the optical signal to a signal conversion device 204 fixedly mounted on the lower side. The signal conversion device is responsible for converting the optical signal into an electrical signal. This conversion process significantly improves the system's response speed and accuracy, ensuring the timeliness and accuracy of line drawing operations.

[0024] Among them, combined Figure 3 As shown, the automatic marking module 3 includes a bracket 301, which helps to provide stable support and offset the impact of mechanical vibration on the marking accuracy. The right side of the bracket 301 includes a transverse sliding groove 302, and a transverse extension arm 303 is slidably connected to the inner side of the transverse sliding groove 302. The inner side of the transverse extension arm 303 includes a longitudinal sliding groove 304, and a longitudinal extension arm 305 is slidably connected to the inner side of the longitudinal sliding groove 304, which realizes the flexible movement of the marking pen in the horizontal and vertical directions, adapts to the cutting requirements of different widths of film materials, expands the horizontal working range, and reduces the space occupied by the equipment. A fixing clip 306 is fixedly installed on the front side of the longitudinal extension arm 305, and a marking pen 307 is fixedly installed on the inner side of the fixing clip 306.

[0025] After receiving the data transmitted by the photoelectric sensor 2, the automatic marking module 3 calculates the position and length of the line according to a preset algorithm using its built-in control unit. Subsequently, the drive motor 302 starts, driving the marking pen 301 to draw lines on the membrane surface. The marking pen 301 is fixedly connected to the output shaft of the drive motor to ensure the stability and continuity of the line drawing. The introduction of this structure enables the automated marking of membrane material during slitting through the collaborative work of the photoelectric sensor 2 and the automatic marking module 3, significantly improving production efficiency. The photoelectric sensor 2 can detect the position and movement speed of the membrane material in real time, providing accurate dynamic data support for the marking. Simultaneously, the signal conversion device converts the optical signal into an electrical signal, further improving the system's response speed and accuracy. Furthermore, the overall structure of this invention is relatively simple and easy to operate, achieving automated marking without complex manual adjustments. The indicator light 202 on the upper side of the sensor body can intuitively display the sensor's working status, facilitating quick troubleshooting and reducing downtime.

[0026] The sensor body 201 is fixedly installed at one end of the frame 102, and the signal conversion device 204 is fixedly installed on the lower side of the bracket 301; the automatic line drawing module 3 is fixedly installed on the right side of the photoelectric sensor 2, and the bracket 301 is fixedly installed on the right side of the frame 102; one end of the wire 205 is fixedly installed on the sensor body 201, and the other end of the wire 205 is fixedly installed on the upper side of the signal conversion device 204; the signal conversion device 204 is fixedly installed on the right side of the frame 102.

[0027] This structural design ensures a stable and rationally arranged connection between the photoelectric sensor 2, the signal conversion device 204, and the automatic marking module 3. The sensor body 201, fixedly mounted at one end of the frame 102, can stably acquire information on the position and speed of the membrane material. The signal conversion device 204, fixedly mounted on the right side of the frame 102 via a bracket 301, not only ensures the stability of the signal conversion process but also facilitates maintenance personnel's inspection and replacement of the device. The wire 205, acting as a bridge connecting the sensor body 201 and the signal conversion device 204, effectively avoids loosening due to vibration or movement. As can be seen, this utility model features a compact overall layout, with all components working collaboratively to achieve the automated marking function for membrane material cutting.

[0028] The working principle of this utility model is roughly based on the following process to achieve the technical objective: When the mechanism is opened, the film material is introduced into the conveyor belt 1 by the unwinding mechanism. The conveyor belt 101 drives the film material to move forward at a constant speed. The frame 102 maintains the flatness of the transmission path. The photoelectric sensor 2 detects the edge position of the film material in real time through the infrared device 203. The signal conversion device 204 feeds the data back to the control system. When the film material reaches the preset cutting point, the automatic marking module 3 is activated. The bracket 301 fixes the transverse sliding groove 302 and drives the transverse extension arm 303 to move along the width direction of the film material. The longitudinal extension arm 305 adjusts the vertical height of the marking pen 307 through the longitudinal sliding groove 304. The fixing clamp 306 ensures that the marking pen stably contacts the film surface to complete the high-precision marking. The marked film material continues to be transported to the cutting station. The whole process does not require manual intervention and realizes the automated closed loop of cutting, positioning and marking.
