[0029] A film cutting device is mounted on a movable module 8 of a cutting machine. The movable module 8 is symmetrically arranged around the film 9 on the cutting machine and includes a cutting component 1. The cutting component 1 includes a mounting bracket 101 and an upper blade 105 and a lower blade 102 rotatably connected to the mounting bracket 101. The mounting bracket 101 is fixed to the movable module 8. The movable module 8 drives the mounting bracket 101 to move laterally around the film 9, while the upper blade 105 and lower blade 102 rotate to cut around the film 9. A photoelectric mounting block 113 and an air blowing block are sequentially arranged at the top of the mounting bracket 101 along the forward direction of the movable module 8. Air blower 111, the air outlet 1112 of the air blower 111 blows air toward the upper cutter 105 and the lower cutter 102. The photoelectric mounting block 113 is provided with air blower 114 and photoelectric sensor 116 in sequence along the forward direction of the moving module 8. The air blower 1141 of the air blower 114 blows air toward the waste material 901 cut off from the adhesive film 9, which is used to blow the waste material 901 downward. The detection end of the photoelectric sensor 116 is located on the same side as the air blower 1141, which is used to detect the edge of the adhesive film 9. When the photoelectric sensor 116 detects that there is a protruding defect 902 on the edge of the adhesive film 9, it triggers the moving module 8 to stop moving forward and feeds back the defect signal.
[0030] like Figures 1 to 8 As shown, this utility model is based on existing conventional film cutting equipment, and is mounted on the moving module 8 of the cutting machine. The moving module 8 can adopt an existing screw-slider assembly, using a rotary motor to drive the screw to rotate, thereby causing the slider to move laterally, as shown. Figure 1 As shown, the adhesive film 9 is laid in a rectangular shape on the cutting machine table. The moving module 8 is symmetrically arranged around the adhesive film 9 on the cutting machine table. The cutting component 1 includes a mounting bracket 101 and an upper blade 105 and a lower blade 102 rotatably connected to the mounting bracket 101. The mounting bracket 101 is fixed to the moving module 8, so that the moving module 8 drives the mounting bracket 101 to move laterally around the adhesive film 9. At the same time, the upper blade 105 and the lower blade 102 rotate to cut around the adhesive film 9. The top of the mounting bracket 101 is provided with a photoelectric mounting block 113 and an air blowing block 111 in sequence along the forward direction of the moving module 8. The air outlet 1112 of the air blowing block 111 faces the upper blade. Air is blown onto the upper and lower cutters 105 and 102 to clean them. An air-blowing block 114 and a photoelectric sensor 116 are sequentially arranged on the photoelectric mounting block 113 along the forward direction of the moving module 8. The air-blowing hole 1141 of the air-blowing block 114 blows air towards the waste material 901 cut from the adhesive film 9, blowing the waste material 901 downwards. The detection end of the photoelectric sensor 116 is located on the same side as the air-blowing hole 1141. The photoelectric sensor 116 can use existing conventional distance sensors and other components, and the detection distance can be set. It is used to detect the edge of the adhesive film 9. When the photoelectric sensor 116 detects a protruding defect 902 at the edge of the adhesive film 9, such as...Figure 7 As shown, there is a protruding defect 902 at the edge of the adhesive film 9. This defect 902 was not properly cut and therefore will not be blown down a great distance by the air column 1143. It will be detected by the detection beam 1161 of the photoelectric sensor 116, indicating that the edge cutting of the adhesive film 9 has not met the normal standard. At this point, the moving module 8 is triggered to stop moving forward and a defect signal is fed back, such as triggering an alarm electrically connected to the photoelectric sensor 116, so that timely maintenance and correction can be carried out by staff. This is efficient and convenient. When the air column 1143 blows downward from the air hole 1141 rapidly blows the waste material 901 downward, such as... Figure 8 As shown, the waste material 901 is far from the photoelectric sensor 116, that is, beyond the detection distance of the photoelectric sensor 116, thus avoiding false judgment.
[0031] In the embodiments of this utility model, optionally, such as Figures 1 to 8 As shown, the mounting bracket 101 has an L-shaped plate structure design.
[0032] In the embodiments of this utility model, optionally, such as Figures 1 to 8 As shown, a drive motor 104 is provided on the L-shaped horizontal plate of the mounting bracket 101. The output end of the drive motor 104 passes through the L-shaped vertical plate of the mounting bracket 101 and is connected to the lower tool holder 103. The lower tool 102 is connected to the lower tool holder 103, so that when the drive motor 104 rotates, it drives the lower tool 102 to rotate at the same time.
[0033] In the embodiments of this utility model, optionally, such as Figures 1 to 8 As shown, the L-shaped vertical plate of the mounting bracket 101 is provided with a bearing 107 with a seat. An upper cutter shaft 106 is inserted through the bearing 107. An upper cutter 105 is connected to one end of the upper cutter shaft 106 that extends out of the bearing 107. A spring 108 is connected between the other end of the upper cutter shaft 106 that extends out of the bearing 107 and the bearing 107. More preferably, a large washer 109 is fixedly connected to the other end of the upper cutter shaft 106 that extends out of the bearing 107 by means of a screw 110. The two ends of the spring 108 are respectively connected between the bearing 107 and the large washer 109. The spring 108 elastically pulls the upper cutter shaft 106 so that the upper cutter 105 is tightly attached to the lower cutter 102. Thus, under the drive of the drive motor 104, the upper cutter 105 and the lower cutter 102 rotate to simulate the cutting action of scissors and achieve the cutting of the film 9.
[0034] In the embodiments of this utility model, optionally, such as Figures 1 to 8 As shown, the bottom end of the air blowing block 111 has a slot 1114, and it is snapped onto the top end of the mounting bracket 101 through the slot 1114. The slot 1114 is fixedly connected to the mounting bracket 101 by screws.
[0035] In the embodiments of this utility model, optionally, such as Figures 1 to 8 As shown, a speed regulating valve 112 is connected to the air inlet 1113 of the air blowing block 111. A sloping groove 1111 is opened at the bottom end of the air blowing block 111. The air outlet 1112 of the air blowing block 111 is located on the sloping groove 1111. The air outlet 1112 is connected to the air inlet 1113. The air inlet 1113 is used to connect to an external air source pipe. The air blowing force of the air outlet 1112 can be adjusted by adjusting the opening of the speed regulating valve 112, thereby realizing the air blowing cleaning of the upper tool 105 and the lower tool 102.
[0036] In the embodiments of this utility model, optionally, such as Figures 1 to 8 As shown, a groove 1131 is provided on one side of the top of the photoelectric mounting block 113. The groove 1131 is fixedly connected to the mounting bracket 101 by screws. The photoelectric sensor 116 is fixedly mounted on the photoelectric mounting block 113. A groove 2 1132 is provided on the other side of the top of the photoelectric mounting block 113. The groove 2 1132 is fixedly connected to the air blowing block 2 114 by screws. Thus, by adjusting the groove 1131, the distance between the photoelectric sensor 116 and the edge of the film 9 can be adjusted. By adjusting the groove 2 1132, the distance between the air blowing hole 1141 of the air blowing block 2 114 and the edge of the film 9 can be adjusted.
[0037] In the embodiments of this utility model, optionally, such as As shown, a speed control valve 115 is connected to the air inlet opening 1142 of the air blowing block 114. The air blowing hole 1141 is connected to the speed control valve 115 through the air inlet opening 1142. The air inlet opening 1142 is used to connect to an external air source pipeline. The air blowing force of the air blowing hole 1141 is adjusted by adjusting the opening degree of the speed control valve 115.
[0038] The method for detecting the cutting of film 9 is as follows:
[0039] S1. The drive motor 104 for cutting the film 9 rotates.
[0040] S2. The rotating cutting blade performs the cutting action under the drive of the moving module 8.
[0041] S3. The cut waste material 901 falls rapidly under the action of the air column 1143 of the air blowing block 2 114.
[0042] S4. During the cutting process, if the detection light column 1161 of the photoelectric sensor 116 is blocked at close range, the photoelectric sensor 116 will send a bad signal to the PLC, and it will be considered that there is a cutting defect at that point.
[0043] S5. If there is no cutting defect, the machine will operate normally; if there is a cutting defect, the machine will stop and alarm, requiring manual intervention.
[0044] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
