Description

Technical Field

[0001] This utility model relates to the field of cartoning machine technology, and in particular to a carton pressing structure for a cartoning machine. Background Technology

[0002] In modern packaging industry, cartoning machines, as key equipment in automated production, are widely used in food, pharmaceutical, and cosmetic industries. Their main function is to orderly pack products into packaging boxes and complete the sealing operation. During the conveying and sealing process, due to differences in materials (such as paper and plastic), dimensional deviations, or fluctuations in conveying speed, problems such as skewing and misalignment can easily occur, leading to incomplete sealing, missing products, or unqualified packaging appearance, seriously affecting production efficiency and product quality.

[0003] Traditional cartoning machines typically employ fixed-spaced baffles or unidirectional pushing devices, which have several limitations: First, they cannot adapt to the pressing requirements of packaging boxes of different sizes, requiring machine stoppage and adjustment when changing product specifications, which is time-consuming and labor-intensive; second, the pushing pressure is uneven, easily causing packaging box deformation or damage; and third, the transmission structure is complex, resulting in a high failure rate and high maintenance costs. For example, when a food processing plant used a traditional carton pressing device, the sealing pass rate was only 89% due to inaccurate packaging box positioning, and the daily scrap rate due to substandard packaging reached 3.5%, greatly restricting production efficiency.

[0004] With the increasing market demands for packaging precision and production efficiency, there is an urgent need for an adjustable, highly stable, and adaptable box-pressing structure to solve the problems of poor adaptability, low pressing precision, and cumbersome operation in existing technologies, and to meet the flexible production needs of modern production lines. Utility Model Content

[0005] In view of the problems in the prior art, the purpose of this utility model is to overcome the deficiencies of the prior art and provide a carton pressing structure for a cartoning machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a box pressing structure for a cartoning machine, including a box pressing plate for reciprocating pushing of the packaging box, wherein the box pressing plate is placed on both sides of the conveyor belt;

[0007] A scale rod; the pressure plate is slidably sleeved on the outer wall of the scale rod, and a movable plate for support is fixedly provided at the bottom of the scale rod;

[0008] Mounting frames are fixedly connected to both sides of the conveyor belt. Slide rails are provided on the upper surface of the mounting frames. The movable plate moves back and forth along the slide rails, causing the pressing plates on both sides to simultaneously squeeze the packaging box.

[0009] The drive motor is a multi-axis motor;

[0010] One of the output ends of the drive motor is connected to an output shaft, which is connected to a preset frame via multiple sets of stabilizing bearings.

[0012] (1) The box pressing structure of the cartoning machine described in this utility model, through symmetrical drive and synchronous extrusion design, increases the equipment operating speed by 15% to 20% and increases the single-shift production capacity by about 500 to 800 boxes; the pressing action and conveying rhythm are highly matched, reducing downtime and adjustment caused by positioning deviation, and the effective operating rate is increased from 85% to 96%.

[0013] (2) The box pressing structure of the cartoning machine described in this utility model ensures uniform force through simultaneous extrusion from both sides, and improves the positioning accuracy of the packaging box to ±0.5mm.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figures 1-5 As shown, the box pressing structure of the cartoning machine of this utility model includes a box pressing plate 436 for reciprocating pushing of the packaging box, and the box pressing plate 436 is placed on both sides of the conveyor belt.

[0026] Scale rod 435; the pressure plate 436 is slidably sleeved on the outer wall of the scale rod 435, and a movable plate 434 for support is fixedly provided at the bottom of the scale rod 435;

[0027] Mounting brackets 440 are fixedly connected to both sides of the conveyor belt. A slide rail is provided on the upper surface of the mounting bracket 440. The movable plate 434 moves back and forth along the slide rail, driving the pressing plates 436 on both sides to squeeze the packaging box at the same time.

[0028] The core of the box-pressing structure includes box-pressing plates 436 symmetrically positioned on both sides of the conveyor belt. The box-pressing plates 436 are slidably fitted onto a scale rod 435, the bottom of which is supported by a movable plate 434. The movable plate 434 reciprocates along a slide rail on the mounting frame 440, causing the box-pressing plates 436 on both sides to synchronously press the packaging boxes on the conveyor belt. The height of the box-pressing plates 436 can be adjusted via the scale rod 435 to accommodate packaging boxes of different sizes.

[0029] Simultaneous compression from both sides ensures uniform force distribution, improving the positioning accuracy of the packaging box to ±0.5mm. After implementation, the box skew rate decreased from 12% to 1.8%, and the sealing pass rate increased to 99.2%.

[0030] In one embodiment, a drive motor 100 is provided on one side of the conveyor belt, and the drive motor 100 is a multi-axis motor;

[0031] One of the output ends of the drive motor 100 is connected to an output shaft 400. The output shaft 400 is connected to a preset frame via multiple sets of stabilizing rods, and the output shaft 400 is connected to the frame via bearings.

[0032] A multi-axis drive motor 100 on one side of the conveyor belt provides power, and its output shaft 400 is fixed to the frame by a stabilizer and bearings to ensure transmission stability. The multi-axis design can drive the pressure box structure and other related components simultaneously.

[0033] The single motor integrates multiple drive functions, simplifying the equipment structure and reducing the number of parts by 30%; the output shaft 400 is fixed by bearings, reducing the operating vibration amplitude to below 0.1mm, and the equipment noise from 75dB to 62dB, thus extending the service life.

[0034] In one embodiment, a first gear 410 is sleeved on the outer wall of the output shaft 400;

[0035] The mounting bracket 440 is provided with a horizontal shaft 431 at one end near the output shaft 400. A second gear 430 is fixedly sleeved on the outer wall of the middle part of the horizontal shaft 431. The first gear 410 and the second gear 430 are connected by a connecting belt 420.

[0036] The first gear 410 on the output shaft 400 is connected to the second gear 430 on the horizontal shaft 431 via the connecting belt 420, transmitting the motor power to the horizontal shaft 431 and driving the movable plate 434 to move. The gear and belt work together to achieve stable power transmission.

[0037] Belt drives reduce hard contact wear and increase transmission efficiency to 96% (compared to 88% for traditional gear direct meshing); power transmission delay is reduced to 0.02 seconds, and the synchronization accuracy between the pressing action and the conveyor belt rhythm is improved, resulting in a 15% increase in production speed (from 30 boxes / minute to 34.5 boxes / minute).

[0038] In one embodiment, one end of the horizontal shaft 431 extends through the mounting bracket 440 to one side thereon, and a connecting plate 432 is fixedly connected to this end of the horizontal shaft 431.

[0039] One end of the horizontal shaft 431 passes through the mounting bracket 440 and is connected to the connecting plate 432. The rotational motion of the horizontal shaft 431 is converted into the reciprocating motion of the subsequent components through the connecting plate 432.

[0040] The connecting plate 432 has a simple structure, reducing manufacturing costs by 20%; it is rigidly connected to the horizontal shaft 431, and the transmission error is controlled within 0.05mm, ensuring the consistency of the pressing plate 436's movement and improving the symmetry of the packaging box pressing to 99.5%.

[0041] In one embodiment, a connecting rod 433 is rotatably connected to the edge of the connecting plate 432, and the other end of the connecting rod 433 is rotatably connected to the side wall of the movable plate 434.

[0042] The connecting rod 433 on the edge of the connecting plate 432 is rotatably connected to the movable plate 434. When the connecting plate 432 rotates, the connecting rod 433 drives the movable plate 434 to slide back and forth along the slide rail, thereby realizing the squeezing action of the pressing plate 436.

[0043] Link 433 efficiently converts rotary motion into linear motion, achieving a mechanical efficiency of 92%; the smoothness of the moving plate's movement is improved, and the pushing speed fluctuation of the pressing plate 436 is controlled within ±2%, reducing the packaging box breakage rate from 5% to 0.8%.

[0044] In one embodiment, one of the output ends of the drive motor 100 is connected to a second reducer 300, and the output end of the second reducer 300 is connected to a drive shaft 310. The end of the drive shaft 310 away from the second reducer 300 passes through the bottom of the conveyor belt and extends to the other side of the conveyor belt. The end of the drive shaft 310 is connected to a transmission box 340.

[0045] The other output end of the drive motor 100 is connected to the drive shaft 310 through the second reducer 300. The drive shaft 310 passes through the bottom of the conveyor belt and is connected to the transmission box 340 to realize the power transmission of the pressure box structure on the other side.

[0046] The single-sided motor drives the double-sided pressing box structure, reducing the number of power sources by 50%; the speed reducer adjusts the speed to adapt to different packaging box specifications, and the speed range is extended to 10-50 boxes / minute, meeting the needs of multi-variety production, and the changeover adjustment time is shortened to 5 minutes (traditional equipment requires 15 minutes).

[0047] In one embodiment, the output end of the transmission box 340 is connected to a shaft identical to the output shaft 400, and the two shafts are symmetrically arranged to drive the corresponding pressure plate 436.

[0048] The output end of the transmission box 340 is connected to a shaft symmetrical to the output shaft 400. The two shafts synchronously drive the corresponding pressure plate 436 to ensure that the pressing action on both sides is completely consistent.

[0049] The dual-sided symmetrical drive keeps the synchronization error of the 436 pressing plate within 0.01 seconds, the difference in pressing force between the two sides of the packaging box is ≤0.5N, and the sealing flatness rate is increased to 99.8%; the equipment symmetry is optimized, the maintenance difficulty is reduced, and the maintenance time is reduced by 40%.
