Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of special intelligent packaging equipment, in particular to a conveying device for corrugated carton packaging. BACKGROUND

[0002] On the automatic packaging production line of corrugated cartons, the conveying device is the key link to realize the conveying, positioning and subsequent packaging of cartons. The running stability and conveying accuracy of the conveying device directly affect the operation efficiency of the whole production line. The existing corrugated carton conveying devices mostly adopt chain or roller structures, and realize the continuous conveying of cartons through motor-driven conveying belts or transmission rollers. However, during high-speed operation or multi-station switching, the cartons are prone to deviation, stacking or dumping, which affects the synchronization accuracy of subsequent packaging. At the same time, when the size of the cartons is switched, some devices need to manually adjust the guide distance or the conveying speed, which is tedious and time-consuming, and is not conducive to the continuous control of the production rhythm.

[0003] In addition, before the corrugated paperboard enters the conveying line, its thickness, hardness and surface flatness often differ. The existing conveying mechanisms lack self-adaptive adjustment functions for these differences. Although some devices use air pressure or elastic support components for simple buffering, they cannot dynamically adjust the conveying pressure and support height according to the thickness variation of the corrugated paperboard, which may cause the paperboard to deform under pressure or the conveying to be unstable. Especially in the multi-layer stacking or cutting synchronization link, the accumulation of conveying errors may cause the cutting tool path to deviate, affecting the size accuracy and packaging quality of the finished cartons.

[0015] Compared with the prior art, the present application has the following beneficial effects:

[0016] 1. In the use process of the present application, the mechanical cooperation of the locking block and the locking groove can accurately limit the stroke range of the jacking protrusion.

[0055] The working principle of the present application is that: in the use process of the device, firstly, the working range of the jacking protrusion 821 is controlled through the matched clamping of the control locking block 822 and the locking groove 811, when the locking block 822 is fixedly inserted in the locking groove 811, the piston rod 82 cannot slide inside the jacking cylinder 81, and the jacking protrusion 821 at the end of the piston rod 82 cannot move to push the corresponding unit knife group 52 to extend or retract, so as to adjust the cutting knife path of the corrugated paper, the base steel frame 11 serves as the bearing foundation of the whole machine, a plurality of corrugated papers are horizontally conveyed through a plurality of rotating rollers 12, after the corrugated paper is conveyed between the two supporting side plates 2, the positioning induction assembly 3 starts to work, the top mounting plate 31 is fixed on the bottom surface of the top supporting arm 21, and the bottom mounting plate 33 is supported on the bottom surface of the top mounting plate 31 through four slide rods 311, when the corrugated paper passes below the plurality of induction rollers 35, the plurality of induction rollers 35 are lifted under the upward force, the rotating supporting arm 331 rotates synchronously with the induction roller 35, so as to drive the bottom mounting plate 33 to slide upwards along the slide rod 311, the four first springs 32 and the corrugated sleeve 34 are compressed in the upward movement of the bottom mounting plate 33, the hydraulic oil in the corrugated sleeve 34 is conveyed to the hydraulic transmission system of the differential rotation assembly 4 through the connecting port 341 under the action of the compression force, so as to realize the preliminary input of hydraulic energy;

[0056] When the servo motor 47 is started, the servo motor 47 drives the rotating main shaft 41 to rotate, the sun gear 411 at the left end of the rotating main shaft 41 rotates, the sun gear 411 is meshed with a plurality of planetary gears 43, the plurality of planetary gears 43 drive the planetary rotating frame 42 to revolve around the sun gear 411, forming the speed difference between the rotating main shaft 41 and the planetary rotating frame 42, the right end of the planetary rotating frame 42 is coaxially and fixedly connected with the outer layer cylinder 51, so that the outer layer cylinder 51 forms an independent rotation speed under the differential action, so that the outer layer cylinder 51 can rotate at a different speed from the rotating main shaft 41, thereby providing dynamic coordination conditions for subsequent cutting actions;

[0057] After the corrugated sleeve 34 is compressed, the hydraulic oil in the corrugated sleeve 34 enters the inside of the fixed cylinder 45 through the water guide pipe 461, and a sealed cavity is formed between the fixed cylinder 45 and the rotating cylinder 46, the hydraulic oil is introduced into the hollow pipe in the rotating main shaft 41 through the sealed cavity, and then flows into a plurality of jacking cylinders 81 through the water inlet pipe 72, the piston rod 82 is slidably connected to the inner wall of the jacking cylinder 81, the hydraulic oil pushes the piston rod 82 to extend outward, the jacking protrusion 821 at the end of the piston rod 82 pushes the stress protrusion 523 in the corresponding unit knife group 52 to move, so as to drive the horizontally placed blade 521 or the vertically placed blade 522 to extend out of the knife hole 512 of the outer layer cylinder 51, thereby realizing the cutting operation on the corrugated paper;

[0058] The outer wall of the rotating main shaft 41 is fixedly provided with a connecting barrel 71. The connecting barrel 71 drives a bearing plate 711 to rotate synchronously with the rotating main shaft 41. A trigger assembly 9 installed at the left end of the bearing plate 711 is driven to participate in control. A sliding rod 93 in the trigger assembly 9 slides against the outer wall of an abutting ring 92 through a sliding wheel 94. When the sliding wheel 94 contacts a lifting lug 921 at the rear end of the abutting ring 92, the sliding rod 93 moves to the left. A connecting rope 95 pulls a ball valve 73 to open a one-way valve, so that hydraulic oil can enter the inside of a jacking barrel 81, and the horizontally placed blade 521 or the vertically placed blade 522 is extended. When the sliding wheel 94 is disengaged from the lifting lug 921, the third spring 74 releases the elastic force to push the ball valve 73 to reset, and the hydraulic passage is closed.

[0059] After a cutting is completed, the connecting barrel 71 continues to drive the bearing plate 711 to rotate synchronously with the rotating main shaft 41. The sliding wheel 94 continues to slide on the left end surface of the abutting ring 92, until the sliding wheel 94 slides against the lifting lug 921 located at the front end of the abutting ring 92. If the corrugated board located directly below the positioning induction assembly 3 is thin at this time, the first spring 32 in the corrugated sleeve 34 releases the reset force. The corrugated sleeve 34 forms an internal negative pressure, and the hydraulic oil in the jacking barrel 81 is reabsorbed into the inside of the corrugated sleeve 34. The piston rod 82 is reset under the action of the second spring 524. The horizontally placed blade 521 and the vertically placed blade 522 are retracted into the space between the outer layer barrel 51 and the inner layer barrel 513. In this way, the self-adaptive cutting of corrugated boards with different thicknesses is realized. At this point, the device has completed the work.
