Description

Technical Field

[0001] This utility model relates to the field of BOPP film processing technology, specifically to a web-aligning device for BOPP film processing. Background Technology

[0002] Biaxially oriented polypropylene (BOP) film is generally a multilayer co-extruded film, made by co-extruded polypropylene granules into sheets, and then stretching them in both longitudinal and transverse directions. Due to the orientation of the stretched molecules, this type of film has good physical stability, mechanical strength, airtightness, high transparency and gloss, and is tough and wear-resistant, making it a widely used printing film.

[0003] For example, a web-aligning device for BOPP film production, with authorization announcement number "CN220165395U", moves a sliding table by rotating a knob, changing the position of the guide rollers for web alignment of the BOPP film. The alignment is performed in the middle by a web-aligning device to ensure that all ends of the BOPP film are in the same position, making it quite practical. However, this device is not convenient for adjusting the length of the guide rollers during use, limiting its ability to handle only one or a limited number of BOPP film sizes for transport and alignment, making its operation somewhat inconvenient. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience in use by proposing a web-aligning device for BOPP film processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a web-correcting device for BOPP film processing, including a base and a tray. The upper end of the base is slidably connected to the tray. The base has a web-correcting structure inside. A first straight plate is fixedly connected to the upper right side of the tray. The upper left side of the tray is in contact with a second straight plate. The right end of the second straight plate has a guide structure. The upper end of the tray has multiple sets of threaded holes.

[0007] Preferably, the guiding structure includes a guide roller and a turntable. The outer wall of the turntable is rotatably connected to the second straight plate through a bearing. The turntable is inserted into one end of the guide roller through a groove on its right end. The right end of the guide roller is inserted into another turntable through a bearing. The outer wall of the other turntable is rotatably connected to the first straight plate through a bearing.

[0008] Preferably, the right end of the second straight plate is symmetrically fixedly connected with through-hole blocks, and the through-hole blocks are all threadedly connected to the threaded holes opened at the upper end of the support plate by bolts.

[0009] Preferably, the upper ends of the first straight plate and the second straight plate are both fixedly connected to a vertical plate, and a CCD camera is installed at one end of each vertical plate.

[0010] Preferably, the correction structure includes a bracket and a servo motor. The bracket is fixedly connected to the base. The bracket is threadedly connected to the servo motor by multiple screws. The output shaft of the servo motor is fixedly connected to one end of a threaded rod. The outer wall of the threaded rod is rotatably connected to two support blocks by bearings. The surface of the threaded rod is threadedly connected to the slider.

[0011] Preferably, the upper end of the slider is fixedly connected to the support plate.

[0012] The present invention discloses a web-aligning device for BOPP film processing, which has the following advantages: Through the cooperation of the guide structure and the pallet, when the BOPP film has different specifications, the operator can remove the bolts on both sides by rotating them and pull the second straight plate to the left. This causes the second straight plate to separate the turntable from the guide roller. The operator can then pull out the guide roller and replace it with a guide roller of different length and with different grooves on the surface. By performing the above operations, the second straight plate is aligned with the threaded holes at different positions, thus completing the fixing of the second straight plate and allowing for continued processing. The ability to replace the guide roller makes the device more convenient for web-aligning and transporting a large number of BOPP films of different specifications, and also makes the device more convenient to use.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-6 In this embodiment, a boppy film processing correction device includes a base 1 and a support plate 4. The upper end of the base 1 is slidably connected to the support plate 4. The base 1 is provided with a correction structure 9. The upper right side of the support plate 4 is fixedly connected to a first straight plate 3. The upper left side of the support plate 4 is in contact with a second straight plate 8. The right end of the second straight plate 8 is provided with a guide structure 2. The upper end of the support plate 4 has multiple sets of threaded holes 5.

[0022] The right end of the second straight plate 8 is symmetrically and fixedly connected with through hole blocks 7. The through hole blocks 7 are all threadedly connected to the threaded holes 5 opened at the upper end of the support plate 4 by bolts 6. The upper ends of the first straight plate 3 and the second straight plate 8 are both fixedly connected with vertical plates 10. A CCD camera 11 is installed at one end of the vertical plate 10. The model of the CCD camera 11 can be FSD-300. The upper end of the slider 904 is fixedly connected to the support plate 4.

[0023] The guide structure 2 includes a guide roller 201 and a turntable 202. The outer wall of the turntable 202 is rotatably connected to the second straight plate 8 through a bearing. The turntable 202 is inserted into one end of the guide roller 201 through a groove opened at its right end. The right end of the guide roller 201 is inserted into another turntable 202 through a bearing. The outer wall of the other turntable 202 is rotatably connected to the first straight plate 3 through a bearing.

[0024] The correction structure 9 includes a bracket 901 and a servo motor 902. The bracket 901 is fixedly connected to the base 1. The bracket 901 is threadedly connected to the servo motor 902 by multiple screws. The servo motor 902 is designed to meet the actual working requirements. The output shaft of the servo motor 902 is fixedly connected to one end of the threaded rod 903. The outer wall of the threaded rod 903 is rotatably connected to two support blocks 905 through bearings. The surface of the threaded rod 903 is threadedly connected to the slider 904.

[0025] Working principle:

[0026] When processing BOPP film:

[0027] The operator attaches the processed BOPP film to the groove on the surface of the guide roller 201, and simultaneously connects one end of the BOPP film to an external winding device. The external winding device pulls and winds the BOPP film, causing the guide roller 201 in this device to rotate synchronously. Under the action of the groove on the surface of the guide roller 201, the BOPP film can be limited. When the specifications of the BOPP film are different, the operator rotates and removes the bolts 6 on both sides, pulls the second straight plate 8 to the left, and causes the second straight plate 8 to drive the turntable 202 to separate from the guide roller 201. The operator pulls out the guide roller 201 and replaces it with a guide roller 201 of different length and with different grooves on the surface. According to the above operation, the second straight plate 8 is aligned with the threaded holes 5 at different positions to complete the fixation of the second straight plate 8, and processing can continue.

[0028] Inspection and correction process:

[0029] The CCD cameras 11 on both sides are controlled to operate, and the CCD cameras 11 take pictures of the edge of the BOPP film and transmit them to the computer for comparison. When the BOPP film is misaligned, the CCD cameras 11 control the servo motor 902 through the controller to operate, so that the output shaft of the servo motor 902 drives the threaded rod 903 to rotate, so that the threaded rod 903 can drive the slider 904 to move, so that the slider 904 drives the support plate 4 to move slowly and synchronously, so that the guide roller 201 can drive the BOPP film to adjust slowly, thereby realizing the correction of the BOPP film.
