[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 1-6 The present embodiment provides a paper feed adjustment mechanism for a packaging box and packaging paper inspection machine, comprising a base plate 1, a first paper guide roller 3 being provided on the base plate 1 through a fixed frame 2, and a second paper guide roller 5 arranged parallel to the first paper guide roller 3 being provided on the fixed frame 2 through a mounting seat 4, the fixed frame 2 being provided with a limiting mechanism 6 for limiting the position of the packaging box and packaging paper on the first and second paper guide rollers 3 and 5 and for cleaning impurities on the surfaces of the first and second paper guide rollers 3 and 5, the mounting seat 4 being movably mounted on the fixed frame 2 through a slide groove 21, and the fixed frame 2 being provided with an adjusting screw 41 movably connected to the mounting seat 4.

[0027] In the present invention, the paper feed adjustment mechanism is installed and fixed at the inlet position of the conveying mechanism of the inspection machine through the base plate 1, and the second paper guide roller 5 is arranged between the mounting seats 4. When the adjusting screw 41 is turned, the mounting seat 4 can be driven to move in the slide groove 21 of the fixed frame 2, thereby adjusting the distance between the second paper guide roller 5 and the first paper guide roller 3 so that it can adapt to the thickness of the packaging paper of the packaging box that needs to be guided. The distance is then adjusted through the limiting mechanism 6 so that the distance of the limiting mechanism 6 can meet the width requirements of the paper, ensuring that the paper always remains on the predetermined path during the transmission process, reducing problems such as paper jams and wrinkles caused by paper deviation or fluctuation. The packaging paper of the packaging box passes through the first paper guide roller 3 and the second paper guide roller 5 of the fixed frame 2 for guide adjustment. After the guide adjustment of the first paper guide roller 3 and the second paper guide roller 5, the paper accurately enters the conveying mechanism and is then sent to the inspection machine by the conveying mechanism.

[0028] Specifically, such as Figure 1-Figure 3 As shown, the limiting mechanism 6 includes a limiting baffle 61, which can move along the length direction of the first paper guide roller 3 and the second paper guide roller 5 through the cooperation of the threaded rod 62 and the guide assembly 63. The limiting baffle 61 includes a first plate body 611 and a second plate body 612 detachably connected by a connecting bolt 613. The guide assembly 63 includes a slide 631 fixed to the bottom of the first plate body 611, and a slide rail 632 fixed on the base plate 1 and cooperating with the slide 631.

[0029] When adjusting the spacing of the limit baffles 61, the operator screws the threaded rod 62 on the fixing frame 2, and the threaded rod 62 moves under the action of the thread, thereby driving the limit baffles 61 to slide along the length direction of the first paper guide roller 3 and the second paper guide roller 5 through the slide 631 and the slide rail 632. When adjusting the paper, the paper passes between the limit baffles 61 and is then guided by the first paper guide roller 3 and the second paper guide roller 5 for adjustment.

[0030] The limit baffle 61 is composed of a first plate body 611 and a second plate body 612. After the first plate body 611 and the second plate body 612 are connected, a slot is formed in the middle. The design of the slot can prevent the limit baffle 61 from interfering with the first paper guide roller 3 and the second paper guide roller 5 when moving. The detachable design of the first plate body 611 and the second plate body 612 can facilitate the disassembly and maintenance of the limit baffle 61.

[0031] Specifically, such as Figure 1 、 Figure 4 and Figure 5 As shown, the limiting mechanism 6 further includes a cleaning assembly 64 detachably mounted on the second plate 612 through a mounting opening 614;

[0032] The cleaning assembly 64 includes a positioning seat 641 that cooperates with the mounting opening 614. A cleaning brush 643 that contacts the first paper guide roller 3 and the second paper guide roller 5 is provided on the positioning seat 641 through a fixing plate 642. Insertion rods 645 are provided at both ends of the positioning seat 641 through a receiving groove 644. A spring 646 is provided between the insertion rod 645 and the inner wall of the receiving groove 644. A pull plate 648 that passes through a through opening 647 is provided on the insertion rod 645.

[0033] A limiting hole that matches the insertion rod 645 is formed on the inner wall of the installation opening 614 .

[0034] Among them, the cleaning brush 643 installed on the positioning seat 641 through the fixing plate 642 abuts against the first paper guide roller 3 and the second paper guide roller 5. When the limit baffle 61 moves, the cleaning assembly 64 moves accordingly, thereby cleaning the first paper guide roller 3 and the second paper guide roller 5. When the first paper guide roller 3 and the second paper guide roller 5 need to be thoroughly cleaned, the first paper guide roller 3 and the second paper guide roller 5 are rotated under the action of an external drive, and the limit baffle 61 is moved while rotating, so that the cleaning area of ​​the cleaning brush 643 can be increased, thereby achieving more effective cleaning of the first paper guide roller 3 and the second paper guide roller 5, removing impurities such as paper scraps attached to the paper guide rollers, thereby preventing impurities such as paper scraps from interfering with the guiding and conveying of paper;

[0035] When the cleaning brush 643 needs to be replaced or cleaned, the user pulls the insertion rod 645 through the pull plate 648, so that the insertion rod 645 squeezes the spring 646 and shrinks in the storage groove 644. At this time, the insertion rod 645 disengages from the limiting hole on the inner wall of the mounting port 614, and then the cleaning brush 643 connected to the positioning seat 641 can be pulled out from the mounting port 614. During installation, the insertion rod 645 is also compressed in the storage groove 644. After the positioning seat 641 is inserted into the mounting port 614, the pull plate 648 is released. The insertion rod 645 pops out and is stuck in the limiting hole under the action of the spring 646, thereby realizing the installation of the cleaning component 64 on the limiting baffle 61, which is convenient for disassembly and assembly.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
