Description

Technical Field

[0002] Cutting is a crucial step in the production of packaging boxes, and the performance of the feeding structure directly affects the cutting accuracy and efficiency. Currently, existing packaging box cutting equipment has several problems with its feeding structure.

[0003] On the one hand, during the feeding process, the cardboard packaging is prone to shifting. This is due to factors such as uneven conveying force and equipment vibration, which cause the cardboard to shift laterally or longitudinally within the conveying channel, leading to deviations in the subsequent cutting position, resulting in a large number of defective or even scrap products, which seriously affects production efficiency and product quality.

[0004] On the other hand, existing feeding structures are insufficient in limiting the vertical movement of the packaging cardboard. During the conveying process, the cardboard may tilt upwards due to vibration or other external forces. This not only affects the smoothness of feeding but may also cause the cardboard to collide with other parts of the equipment, damaging the cardboard or the equipment. It also reduces the stability of the cardboard during cutting, further reducing the cutting accuracy. Therefore, a feeding structure for packaging box cutting equipment has been proposed to solve the above problems. Utility Model Content

The output shaft of the drive motor 7 passes through the frame 1 and is fixedly connected to one end of the main shaft 2. When the drive motor 7 starts, it drives the main shaft 2 to rotate, which in turn causes the active conveying rollers 3 to rotate. The conveyor belt 6 then drives the driven conveying rollers 5 and the secondary shaft 4 to rotate, thereby conveying the packaging cardboard.

[0026] The correction and limiting mechanism is installed on the outer wall of the frame 1 and is used to correct and limit the cardboard of the packaging box during the conveying process.

[0027] The deviation rectifying and limiting mechanism further comprises mounting racks 8 fixedly connected to the outer walls of the middle sections of the two sides of the rack 1, servo motors 9 fixedly installed on the top middle sections of the outer walls of the mounting racks 8, gear wheels 10 fixedly connected to the output shafts of the servo motors 9 and penetrating through the mounting racks 8, two gear racks 14 welded to the top outer walls of the two side plates 13, and the two gear racks 14 engaged with the gear wheel 10; when the servo motors 9 rotate, the gear wheel 10 is driven to rotate, and the relative movement of the two side plates 13 is realized through the engagement of the gear wheel 10 and the gear racks 14, so that the deviation rectifying and limiting of the packaging box paperboard during the conveying process is realized.

[0028] The outer walls opposite to the two side plates 13 are welded with fixing frames 15, the inner walls of the two ends of the fixing frames 15 are rotatably connected with bidirectional screws 19, the outer walls of the bidirectional screws 19 are symmetrically and threadedly connected with two screw blocks 21, the bottom outer walls of the two screw blocks 21 are rotatably connected with connecting rods 22, the bottom ends of the connecting rods 22 are rotatably connected to the top outer walls of the pressing plates 17 through shaft seats, the outer walls of one ends of the two fixing frames 15 are respectively fixedly installed with stepping motors 20, and the output shafts of the two stepping motors 20 are respectively penetrated through the fixing frames 15 and fixedly connected with one ends of the two bidirectional screws 19; when the stepping motors 20 rotate, the bidirectional screws 19 are driven to rotate, and the two screw blocks 21 are relatively or oppositely moved due to the thread characteristics of the bidirectional screws 19, the pressing plates 17 are driven to move downward or upward through the connecting rods 22, and the vertical limiting of the packaging box paperboard is realized.

[0029] The top outer walls of the fixing frames 15 are fixedly connected with a plurality of telescopic rods 16, the telescopic ends of the plurality of telescopic rods 16 are penetrated through the fixing frames 15 and fixedly connected with the top outer walls of the pressing plates 17, and the plurality of telescopic rods 16 are evenly distributed at the top four corner edge positions of the pressing plates 17; the telescopic rods 16 play the role of auxiliary support and stabilization of the pressing plates 17, and ensure the stable upward and downward movement of the pressing plates 17.

[0030] The bottom outer walls of the pressing plates 17 are rotatably connected with a plurality of compression rollers 18 through shafts; when the packaging box paperboard is conveyed on the conveying belt 6, the compression rollers 18 roll above the paperboard, which can limit the paperboard and prevent it from being upwardly warped, and can also reduce the friction on the surface of the paperboard, so as to ensure the smoothness of the paperboard conveying.

[0031] The outer walls of the two sides of the rack 1 are fixedly connected with a plurality of support frames 11, the outer walls of the support frames 11 are slidably connected with slide rods 12, and the one ends of the plurality of slide rods 12 towards the conveying belt 6 are respectively fixedly connected to the outer walls of the two side plates 13; the support frames 11 and the slide rods 12 provide guidance and support for the relative movement of the side plates 13, and ensure the stability of the movement of the side plates 13.

[0033] When it is detected that the packaging box paperboard deviates during conveying (the detection can be performed by a sensor installed on the rack 1, not shown in the figure), the servo motor 9 is started, the output shaft of the servo motor 9 drives the gear 10 to rotate, the gear 10 is engaged with the rack 14 at the top of the side plate 13, so that the two side plates 13 relatively approach or move away from each other, for example, when the paperboard deviates to one side, the servo motor 9 drives the gear 10 to rotate, so that the side plate 13 close to the deviation direction moves towards the paperboard, and the paperboard is pushed back to the correct conveying path, so that the deviation correction function is realized;

[0034] According to the thickness of the packaging box paperboard, the stepping motor 20 is started, the output shaft of the stepping motor 20 drives the bidirectional screw rod 19 to rotate, the two screw blocks 21 on the bidirectional screw rod 19 relatively or oppositely move due to the thread, the movement of the screw blocks 21 drives the lower pressing plate 17 to move downward or upward through the connecting rod 22, when the lower pressing plate 17 moves downward, the pressing roller 18 contacts the packaging box paperboard and applies a certain pressure to the paperboard, so that the paperboard is prevented from being raised upward, and meanwhile, the telescopic rod 16 telescopes along with the movement of the lower pressing plate 17, so as to assist in supporting and stabilizing the lower pressing plate 17;

[0035] During the relative movement of the side plate 13, the support frame 11 and the slide rod 12 provide guidance and support for the side plate 13, so that the side plate 13 moves stably, and during the conveying, deviation correction and limiting of the whole feeding structure, the components work cooperatively, so that the stability of the packaging box paperboard conveying and the cutting precision are ensured.
