Description

Technical Field

[0001] The utility model relates to the technical field, in particular to an edge trimming machine for BOPP film production. Background Art

[0002] BOPP film (biaxially oriented polypropylene film) is a polymer film widely used in packaging, printing and labeling. It has high strength, good transparency, excellent barrier properties and stiffness, as well as excellent moisture resistance and chemical corrosion resistance. When producing BOPP film, it needs to be trimmed.

[0003] For example, the trimming machine for BOPP film production with the authorization announcement number "CN207607021U" can trim the edges of both sides of the film before winding it through the cooperation of the cutter and the shaft sleeve. It is simple to operate, easy to use, and has high work efficiency. It ensures the flatness of the film edge and improves the film quality. However, the device can only achieve the width of the edge material cut by the cutter by adjusting the position of the shaft sleeve by locking the locking screw on the shaft sleeve position. The operator needs to manually adjust the position of the shaft sleeve, which increases the workload of the operator and reduces the work efficiency of the device. When the device trims and cuts the BOPP film, the distance between the two guide rollers is fixed, and the tension between the BOPP film cannot be adjusted, which easily causes the trimming and cutting position to change, affecting the trimming effect and reducing the trimming quality of the device.

[0025] Working principle:

[0026] BOPP film production cutter trimming adjustment process:

[0027] The operator sleeves the BOPP film roll on the surface of the guide roller 5, and after winding it on the surface of the winding roller 9, the external power supply of the first motor 201 is turned on, and the output shaft of the first motor 201 is started to rotate to drive the stud 202 to rotate. The stud 202 rotates to drive the threaded block 203 to move, and the threaded block 203 drives the first shell 205 to move. The first shell 205 drives the surface cutter 8 to move synchronously to a suitable position and stop, and adjusts the width of the cutter 8 for the BOPP film trimming. When the cutter 8 needs to be replaced, the pull block 210 is pulled to drive the clamping block 208 to move horizontally, and it is no longer clamped with the groove on the surface of the cutter 8. The clamping block 208 compresses the spring 209, and the operator takes out the cutter 8 for replacement. After replacement, the cutter 8 is inserted into the first shell 205. Under the reverse force of the spring 209, the clamping block 208 is clamped with the groove on the surface of the cutter 8, and the position of the cutter is fixed, completing the trimming adjustment process of the BOPP film production cutter.

[0028] Tension adjustment process during BOPP film production:

[0029] When trimming the BOPP film, it is necessary to adjust the spacing between the BOPP films to control the tension. The external power supply of the second motor 301 is turned on, and the output shaft of the second motor 301 is started to rotate to drive the worm 303 to rotate. The rotation of the worm 303 drives the worm wheel 304 to rotate. The rotation of the worm wheel 304 drives the rotating rod 305 to move. The rotating rod 305 drives the third support block 10 and the winding roller 9 to move horizontally away from the second support block 6, thereby increasing the spacing between the second support block 6 and the third support block 10 and increasing the tension of the BOPP film. After the third support block 10 moves, the worm wheel 304 and the worm 303 have a self-locking feature, which will not cause the third support block 10 to deviate, so that the tension adjustment process of the BOPP film during trimming can be completed more accurately during trimming.
