Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carton packaging, in particular to a paper box inner material shaking and leveling device. BACKGROUND

[0002] In the packaging industry, the uniform stacking and compaction of the materials in the paper box is a key link to ensure the packaging quality.

[0003] At present, the traditional material shaking and leveling method relies on manual operation, and the materials are leveled by manually patting and pressing the paper box. This method is not only inefficient and labor-intensive, but also difficult to ensure the compaction degree and uniformity of the materials. SUMMARY

[0004] In view of the above technical problems, the present application solves the problem that the traditional material shaking and leveling method relies on manual operation, and the materials are leveled by manually patting and pressing the paper box. This method is not only inefficient and labor-intensive, but also difficult to ensure the compaction degree and uniformity of the materials.

[0005] In order to achieve the above purpose, the technical solution adopted by the present application is that the paper box inner material shaking and leveling device comprises a conveying structure, a blocking structure, a shaking structure and a pressing structure. The conveying structure serves as a basic carrier, and roller assemblies are arranged between the mounting beams at the top of the conveying frame of the conveying structure, and a stable paper box conveying area is formed in cooperation with the strip-shaped guide plates. A first motor and a speed reducer drive a chain wheel-chain transmission system to ensure stable conveying of the paper box.

[0006] The blocking structure and the shaking structure are arranged below the roller assemblies, and the two structures cooperate to complete the positioning of the paper box and the lifting of the materials. A first hydraulic telescopic rod controls the lifting of the blocking plate to realize accurate positioning of the paper box, and a second hydraulic telescopic rod drives the shaking structure to rise, so that the shaking vertical plate is inserted into the bottom of the paper box to prepare for subsequent shaking and leveling operation.

[0007] The shaking structure is the core of realizing uniform distribution of the materials. A second motor drives the rotation of the rotating disc, and the rotating rod eccentrically arranged on the rotating disc drives the follower block to make the shaking vertical plate produce horizontal, vertical and combined direction shaking, so as to promote the materials in the paper box to move fully and eliminate the accumulation and voids.

[0008] The pressing structure is located above the conveying area, and a double-acting double-rod hydraulic cylinder drives the intermittent pressing of the pressing plate. In cooperation with the shaking vertical plate, the pressing plate synchronously applies pressure during the shaking of the materials to ensure that the materials are compacted and stacked evenly.

[0009] The technical solution provided by the present application has the following beneficial effects compared with the prior art:

[0010] 1. In this invention, the device integrates conveying, blocking, shaking and pressing functions into one unit. Through the coordinated control of motor, hydraulic telescopic rod and hydraulic cylinder, it realizes full automation of the entire process from carton conveying, positioning, material shaking and compaction to output, greatly reducing manual intervention and significantly improving packaging operation efficiency.

[0011] 2. In this invention, the eccentric rotation design of the turntable in the shaking structure can drive the shaking vertical plate to achieve horizontal, vertical and multi-directional compound shaking. Combined with the intermittent and precise pressing of the pressing structure, the material moves fully and is evenly distributed in the carton, effectively solving the problems of material accumulation and unevenness, ensuring that the material is stacked tightly and flat, and improving the packaging quality.

[0012] 3. In this invention, the conveying structure adopts a sprocket-chain transmission system, which provides stable power transmission and can adapt to the conveying of cartons of different specifications; the layered design of the blocking structure and the shaking structure, through the hydraulic telescopic rod, achieves independent lifting and lowering, avoids component interference, and ensures the reliability of equipment operation; the double-acting double-rod hydraulic cylinder of the pressing structure, together with the guide column and T-shaped guide bar, ensures that the pressing plate pressing process is smooth and the positioning is accurate.

[0013] 4. In this invention, the parameters of each key component of the device (such as the roller assembly, the shaking vertical plate, and the pressure plate) can be flexibly adjusted according to the carton size and material type, which can meet diverse packaging needs and is widely applicable to carton packaging scenarios in various industries such as food, daily necessities, and industrial products.

[0014] 5. In this invention, the stable structural design reduces equipment failure rate and extends service life, while the precise leveling and compaction effect reduces material waste, thereby reducing the production and operation costs of enterprises from multiple aspects.

[0037] Working principle:

[0038] The top of the packaging carton is in an open state in advance, and the inside is provided with the to-be-pressed articles.

[0039] The packaging carton of the last process is put on the roller 103, and the roller 103 moves (start the first motor 109, the first motor 109 drives the reduction gear 110 to rotate, the reduction gear 110 drives an adjacent roller 103 to rotate through the first chain 111, and the adjacent two rollers 103 are driven to rotate through the second chain 112, until all the rollers 103 are driven to rotate, thereby moving the packaging carton on the roller 103), start the first hydraulic telescopic rod 206, so that the telescopic end of the first hydraulic telescopic rod 206 moves up, thereby making the baffle plate 204 move up, until the top of the baffle plate 204 is above the highest position of the roller 103. When the front end of the moving packaging carton is blocked by the baffle plate 204, the operator stops the first motor 109, and finally makes the roller 103 stop rotating (of course, the first motor 109 can also be automatically stopped in a mature and automatic manner). At this time, start the second hydraulic telescopic rod 207 (multiple second hydraulic telescopic rods 207 move up synchronously, before use, the operator adjusts them in a mature and existing debugging manner, so that all the second hydraulic telescopic rods 207 can move up synchronously and keep the same pace). All the second hydraulic telescopic rods 207 can move up synchronously, driving the first support plate 201 and the second support plate 301 to move up (in this process, the guide part 203 slides up relative to the baffle plate 204, and the baffle plate 204 remains unchanged), until the top of all (or part) of the shaking vertical plate 311 moves up and lifts the packaging carton. Start the double-acting double-rod hydraulic cylinder 505, so that the upper piston rod 506 of the double-acting double-rod hydraulic cylinder 505 moves down synchronously with the lower piston rod 506 of the double-acting double-rod hydraulic cylinder 505, thereby synchronously pressing the connecting sheet 508 and the pressing plate 509, until the pressing plate 509 presses on the articles in the packaging carton, and then start the second motor 40, so that the output end of the second motor 40 drives the rotating disc rotating shaft 315 to rotate, thereby making the rotating disc 314 rotate, and the eccentric moving of the rotating rod 313 drives the follower block 308 to shake (forming a trajectory synchronous with the eccentric movement of the rotating rod 313, in a single horizontal direction, the whole of the follower block 308, the transition part 309, the top plate 310, the shaking vertical plate 311, the vertical plate 303, the bottom side plate 304 and the top side plate 305 reciprocate along the axial direction of the horizontal rod 306, in a single vertical direction, the whole of the follower block 308, the transition part 309, the top plate 310 and the shaking vertical plate 311 reciprocate along the axial direction of the vertical rod 307, and in other directions, they move in a synchronous combination direction of the single horizontal direction and the single vertical direction. For example, when the rotating rod 313 moves to the rear upper side, the whole of the follower block 308, the transition part 309, the top plate 310, the shaking vertical plate 311, the vertical plate 303, the bottom side plate 304 and the top side plate 305 move along the axial direction of the horizontal rod 306 and are closer to the rear side of the conveying structure 10.At the same time, the servo block 308, the transition part 309, the top plate 310, and the whole of the shaking vertical plate 311 are moved along the axial direction of the vertical rod 307 and are closer to one side of the pressing structure 50. At the same time, the double-acting double-rod hydraulic cylinder 505 is intermittently started, the pressing plate 509 is intermittently pressed to the articles in the packaging carton, and the shaking vertical plate 311 cooperates with the pressing plate 509 (at least including simultaneous opposite actions, so that the articles are tightly packed (compacted), and at the same time, the shaking of the shaking vertical plate 311 further makes the articles tightly packed (compacted)). When the articles are neatly stacked (compacted), the double-acting double-rod hydraulic cylinder 505 is started to move the pressing plate 509 upward, the second motor 40 is stopped, the second hydraulic telescopic rod 207 is reversely started to reset the second hydraulic telescopic rod 207, so that the shaking vertical plate 311 is moved downward, then the first hydraulic telescopic rod 206 is reversely started to move the blocking plate 204 downward, and finally the first motor 109 is started again to move the roller 103, so that the whole packaging carton and the articles in it are moved into the next process.

Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
