Description

Technical Field

[0001] This utility model belongs to the field of decorative paper processing technology, and specifically relates to a decorative paper correction and positioning mechanism. Background Technology

[0002] The decorative paper correction and positioning mechanism is an important equipment component used in the production, printing, and lamination processes of decorative paper. Its main function is to automatically detect the positional deviation of the decorative paper during the conveying process and correct the deviation through a mechanical adjustment device to ensure that the decorative paper is always accurately conveyed along the predetermined path, avoiding problems such as printing misalignment, uneven lamination, and material waste caused by deviation.

[0003] Currently, Chinese utility model patent CN222042098U discloses a decorative paper correction and positioning mechanism, including a base with support columns at the four corners of the bottom of the base, a fixing component on one side of the base, a feeding roller on the fixing component, a rotating seat on the side of the base near the feeding roller, a correction component on the top of the rotating seat, a guide component on the bottom of the rotating seat, a drive component for driving the rotating seat to rotate, and a monitoring component on the top of the base away from the feeding roller. A photoelectric distance sensor detects whether the decorative paper deviates during transmission. When deviation is detected, an electric cylinder and a motor are started, respectively, driving the feeding roller to move and the guide roller to rotate. This quickly corrects the deviation of the decorative paper along the axial direction and axial angle of the guide roller, compensating for deviation during printing and preventing problems such as unclear printing or overlapping marks.

[0004] During use, the correction and positioning mechanism cannot quickly clean the dust adhering to the surface of the drive shaft in the device. As a result, when assisting in the correction of the decorative paper during transfer, the dust adhering to the surface of the drive shaft will be transferred to the surface of the decorative paper, affecting the appearance and performance of the decorative paper. In addition, when the correction and positioning mechanism is damaged, the staff needs to disassemble and repair the entire correction and positioning mechanism and the positioning frame in the transport component, which results in excessive time consumption during the disassembly process and affects the normal use of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a decorative paper correction and positioning mechanism, which has the advantages of being able to clean the dust on the surface of the drive shaft in real time and to quickly disassemble the damaged correction and positioning mechanism and the positioning frame in the transport assembly.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a decorative paper correction and positioning mechanism, including a positioning frame, a mounting frame on the top of the positioning frame, a hydraulic rod fixedly mounted on the side frame of the top of the mounting frame, the front side of the hydraulic rod fixedly mounted to the mounting frame, a distance sensor snapped onto the right side of the mounting frame, a connecting wire connected to the rear side of the distance sensor, the front side of the left side of the connecting wire connected to the hydraulic rod, a positioning rod fixedly mounted in the inner cavity of the mounting frame, a positioning shaft slidably connected to the surface of the positioning rod, a cleaning component fixedly mounted on the top of the inner cavity of the mounting frame, the cleaning component including a sponge block, the top of the sponge block contacting the positioning shaft, three fixing components snapped onto both sides of the mounting frame, each fixing component including a fixing shell, the surface of the fixing shell snapping onto the inner cavity of the mounting frame.

[0014] The present invention is further configured such that a limiting frame is slidably connected to the top of the movable frame, and the inner cavity of the limiting frame is slidably connected to the mounting shell.

[0015] The above technical solution is adopted: by setting a limit frame, the fixed position of the movable frame is positioned during use to prevent the movable frame from fixing the fixed frame during use.

[0016] The present invention is further configured such that a knob is rotatably connected to the top of the inner cavity of the fixed shell, a gear 1 is fixedly installed at the bottom of the knob, a retaining frame is rotatably connected to the bottom of the gear 1, the surface of the retaining frame is in contact with the inner cavity of the fixed shell, four gears 2 are rotatably connected to the bottom of the inner cavity of the retaining frame, the side of the gear 2 near the gear 1 meshes with the gear 1, the bottom of the gear 2 extends through to the outside of the retaining frame and a locking rod is fixedly installed thereon, and the top of the locking rod is slidably connected to the retaining frame.

[0017] The above technical solution involves rotating a knob to rotate gear one, which in turn drives gear two to engage, thus securing the mounting bracket and positioning bracket during installation via a locking rod, and enabling quick disassembly of the mounting bracket and positioning bracket when disassembly is required.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. When the user needs to clean the dust on the surface of the positioning shaft in real time, the user puts the retaining bracket into the mounting housing and uses the limit spring, movable bracket and locking block to complete the positioning. After the scraper and sponge block come into contact with the positioning shaft, the dust attached to the surface of the positioning shaft can be cleaned during use.

[0020] 2. During maintenance, when it is necessary to quickly disassemble the alignment positioning mechanism and the positioning frame, the user can rotate the knob to engage gear one and gear two, reset the locking plate, and then detach the mounting bracket from the positioning frame. This allows for quick disassembly of the alignment positioning mechanism and the positioning frame during maintenance. Attached Figure Description

[0028] refer to Figure 1 , Figure 2 and Figure 3 A decorative paper correction and positioning mechanism includes a positioning frame 1, a mounting frame 2 on the top of the positioning frame 1, a hydraulic rod 3 fixedly mounted on the side frame of the top of the mounting frame 2, the front side of the hydraulic rod 3 fixedly mounted to the mounting frame 2, a distance sensor 4 snapped onto the right side of the mounting frame 2, a connecting line 5 connected to the rear side of the distance sensor 4, the front side of the left side of the connecting line 5 connected to the hydraulic rod 3, a positioning rod 6 fixedly mounted in the inner cavity of the mounting frame 2, a positioning shaft 7 slidably connected to the surface of the positioning rod 6, and a cleaning component 8 fixedly mounted on the top of the inner cavity of the mounting frame 2, the cleaning component 8 including a sponge block 806, the top of the sponge block 806 contacting the positioning shaft 7.

[0029] Furthermore, the cleaning component 8 includes a mounting housing 801, the bottom of which is fixed to the inner wall of the mounting bracket 2. A movable bracket 802 is movably connected to the inner cavity of the mounting housing 801. A limit spring 803 is fixedly installed at the bottom of the inner cavity of the movable bracket 802. The top of the limit spring 803 is fixedly installed to the inner wall of the mounting housing 801. A fixed bracket 804 is slidably connected to the bottom of the movable bracket 802. A scraper 805 is fixedly installed at the top of the fixed bracket 804. The top of the scraper 805 contacts the surface of the positioning shaft 7. The inner cavity of the fixed bracket 804 is fixedly installed to the sponge block 806.

[0030] Furthermore, three locking blocks 807 are fixedly installed at the bottom of the movable frame 802, and the bottom of the locking blocks 807 engages with the inner cavity of the fixed frame 804.

[0031] Furthermore, a slider 808 is fixedly installed on the left side of the movable frame 802, and the right side of the slider 808 is slidably connected to the mounting shell 801.

[0032] Furthermore, the top of the movable frame 802 is slidably connected to a limiting frame 809, and the inner cavity of the limiting frame 809 is slidably connected to the mounting shell 801.

[0033] Brief description of usage: When the user senses the decorative paper being transported by the positioning shaft 7 through the distance sensor 4, if the distance sensor 4 detects a shift in the position of the passing decorative paper, the hydraulic rod 3 is controlled via the connecting cable 5 to move the positioning rod 6 and the positioning shaft 7, which are fixed in a movable position inside the mounting bracket 2, to complete the correction. During the correction process, it is necessary to clean the dust on the surface of the positioning shaft 7 in real time. If the distance sensor 4 senses a shift in the position of the passing decorative paper being transported by the positioning shaft 7 through the distance sensor 4, the hydraulic rod 3 is controlled via the connecting cable 5. 3. The positioning rod 6 and positioning shaft 7, which are fixed in a movable position inside the mounting bracket 2, are moved to complete the correction. During the correction process, if it is necessary to clean the dust on the surface of the positioning shaft 7 in real time, the user first separates the limiting bracket 809 from the movable bracket 802 and the mounting shell 801. Then, the user puts the fixing bracket 904 into the mounting shell 801. The user then uses the limiting spring 803 to drive the movable bracket 802 and the locking block 807 to lock the fixing bracket 904, thus completing the positioning of the fixing bracket 904. The scraper 805 and the sponge block 806 then contact the positioning shaft 7. Finally, the user moves the limiting bracket 809 to the mounting shell 801. 9. After re-engaging with the movable bracket 802, dust on the surface of the positioning shaft 7 can be scraped off by the scraper 805, or dust that the scraper 805 cannot clean can be wiped off by the sponge block 806. This completes the cleaning of dust adhering to the surface of the positioning shaft 7 during use. By setting the mounting shell 801 in the cleaning component 8, the user can install the retaining bracket 904 and position the retaining bracket 904. By setting the movable bracket 802 and the limit spring 803, the position of the retaining bracket 904 can be positioned during use to prevent the retaining bracket 904 from deviating during use. The movable frame 802 is fixed to the fixed frame 804 by a scraper 805 and a sponge block 806, which clean the dust on the surface of the positioning shaft 7 during use. The fixed frame 804 is reinforced by a locking block 807 to prevent it from shifting during use. The fixed frame 804 is detached by a slider 808 to facilitate cleaning of the scraper 805 and sponge block 806. The movable frame 802 is fixed in place by a limit frame 809 to prevent it from fixing the fixed frame 804 during use.

The bottom of the gears 905 extends through to the outside of the retaining frame 904 and a locking rod 906 is fixedly installed thereon. The top of the locking rod 906 is slidably connected to the retaining frame 904.

[0037] Brief description of usage: During maintenance, when it is necessary to quickly disassemble the alignment positioning mechanism and positioning frame 1, the user can rotate the knob 902 to engage gear 1 903 and gear 2 905, causing the locking rod 906 to move in a circular motion and re-enter the groove of the retaining frame 904. Then, the mounting frame 2 can be disengaged from the positioning frame 1, thus completing the quick disassembly of the alignment positioning mechanism and positioning frame 1 during maintenance. By rotating the knob 902, gear 1 903 is rotated, which in turn drives gear 2 905 to engage. This completes the fixing of the mounting frame 2 and positioning frame 1 by the locking rod 906 during installation and the quick disassembly of the mounting frame 2 and positioning frame 1 when disassembly is required.
