Description

Technical Field

[0001] This utility model relates to the field of cardboard box production equipment technology, and specifically to a cardboard box stacking mechanism on a cardboard box stacking equipment. Background Technology

[0002] Cardboard boxes, as an important material in the packaging industry, are widely used in the packaging and transportation sector due to their advantages such as durability, ease of processing, low cost, recyclability, and environmental friendliness. In the cardboard box production process, how to stack cardboard boxes orderly and stably to facilitate subsequent packaging, transportation, and storage has always been a crucial issue in the cardboard box manufacturing industry.

[0003] In traditional cardboard box production lines, cartons are typically conveyed sequentially with gaps between adjacent cartons. A specific example can be found in Chinese invention patent application number 202310550037.0, which discloses a double-sided conveyor printing production line for cardboard box production. While this method ensures stability and independence of the cartons during transport to some extent, it also presents several drawbacks. For instance, the gaps between adjacent cartons reduce space utilization on the production line, thus impacting overall production efficiency. Furthermore, the gaps between cartons result in a relatively long conveying time. This is especially true on low-speed production lines, where the gaps further extend the conveying time and reduce efficiency. Additionally, if cartons fail to adhere tightly to the conveyor belt during transport, stacking stability may be affected. This is particularly problematic in subsequent processing stages (such as packaging and transportation), where unstable stacks are more prone to collapse and misalignment, negatively impacting the stability and efficiency of the production line. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a carton stacking mechanism on a carton stacking equipment.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A carton stacking mechanism on a carton stacking device includes a support frame, and a conveying assembly, a baffle assembly, and an adsorption assembly mounted on the support frame. The conveying assembly is located at the top of the support frame, the baffle assembly is located at the input end above the conveying assembly, and the adsorption assembly is located inside the conveying assembly. The baffle assembly blocks and guides the input cartons onto the conveying assembly, and the adsorption assembly adsorbs the cartons on the conveying assembly. The baffle assembly includes support plates fixed to both sides of the top of the support frame, a baffle plate rotatably fitted between the two support plates, and a drive air rod mounted on one side support plate for rotating the baffle plate. The bottom of the baffle plate is offset in the conveying direction to form an inclined guide surface at the input end. The distance between the bottom edge of the baffle plate and the top plane of the conveying assembly only allows the stacked cartons to pass through. The drive air rod rotates the baffle plate, changing the distance between the bottom edge of the baffle plate and the top plane of the conveying assembly. Multiple sets of conveying assemblies and adsorption assemblies are provided, and differential conveying can be achieved between the multiple sets of conveying assemblies. When the stacked cardboard passes between two sets of conveying assemblies, it can be separated by differential conveying.

[0007] In this invention, the brush baffle assembly is provided in multiple sets along the conveying direction, and the multiple sets of brush baffle assemblies are arranged sequentially at intervals.

[0008] Furthermore, when the brush baffle assembly near the input end is used to block the carton and cause the carton to stack, the rear brush baffle assembly adjusts the brush baffle to a horizontal state via the drive air rod, or adjusts the brush baffle to the same angle as the front brush baffle used to block the carton.

[0009] Furthermore, when using a deflector assembly located away from the input end to block the carton and cause it to stack, the deflector assembly in front of the deflector assembly rotates the deflector plate to a more horizontal position, while the deflector assembly behind it adjusts the deflector plate to a more horizontal position, or at an angle similar to that of the deflector plate in front used to block the carton.

[0010] Furthermore, the drive air rods on the multiple sets of the aforementioned brush assemblies are alternately arranged at their left and right ends.

[0011] In this utility model, the brush baffle includes a connecting shaft and a baffle. The connecting shaft is a square shaft. The top of the baffle is connected to the side of the connecting shaft by welding. The baffle is connected to the side of the connecting shaft near the input end. The two ends of the connecting shaft are rotatably fitted with bearing seats. The brush baffle is mounted on the two side support plates through the bearing seats at both ends.

[0012] Furthermore, cylindrical rotating shafts extend outward from both ends of the connecting shaft. The connecting shaft cooperates with the bearing seat through the rotating shaft. A driving block is also provided on the rotating shaft. One end of the driving block is fixedly connected to the rotating shaft, and the other end is hinged to the driving end of the driving air rod. When the driving air rod moves, it drives the rotating shaft to rotate through the driving block, thereby causing the baffle to flip.

[0013] In this utility model, the conveying assembly includes a drive shaft, a driven shaft, and a drive motor rotatably mounted on a support frame, as well as a conveyor belt sleeved on the drive shaft and the driven shaft. The drive motor drives the drive shaft to rotate, and the conveyor belt is breathable and forms a conveying surface on its top.

[0014] Furthermore, the adsorption assembly includes an air suction pipe mounted on a support frame and an air guide pipe connected to one end of the air suction pipe. The air suction pipe is located below the conveying surface and has several air suction ports. The air guide pipe is connected to a blower. When the blower is activated, a downward negative pressure is generated on the conveying surface to press the carton firmly against the conveying surface.

[0015] This utility model has the following advantages and beneficial effects:

[0016] The support frame is equipped with a conveying component, a baffle component, and an adsorption component. The bottom of the baffle plate in the baffle component is offset towards the conveying direction, thus forming an inclined guide surface at the input end. When the carton enters from the input end, it first impacts the guide surface and is then guided to the conveying component for stacking. After stacking, the carton can be adsorbed onto the conveyor belt by the adsorption component during the conveying process, ensuring the stability of the conveying. In addition, the stacked carton not only significantly improves space utilization but also conveying efficiency, thereby ensuring overall production efficiency. Moreover, the stacked carton is easier to stack when output, improving stacking efficiency and stability after stacking, ensuring the normal operation of subsequent processes.

However, this utility model is not limited to the following embodiments.

[0025] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0026] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0027] like Figures 1 to 6As shown, this embodiment discloses a carton stacking mechanism on a carton stacking device, including a support frame 1, and a conveying assembly 2, a baffle assembly 3, and an adsorption assembly 4 mounted on the support frame 1. The conveying assembly 2 is located at the top of the support frame 1, the baffle assembly 3 is located at the input end above the conveying assembly 2, and the adsorption assembly 4 is located inside the conveying assembly 2. The baffle assembly 3 blocks and guides the input cartons onto the conveying assembly 2, and the adsorption assembly 4 adsorbs the cartons on the conveying assembly 2. Specifically, the baffle assembly 3 includes support plates 31 fixed on both sides of the top of the support frame 1, a baffle plate 32 rotatably fitted between the two support plates 31, and a drive air rod 33 mounted on one side support plate 31 for driving the baffle plate 32 to rotate. The bottom of the baffle plate 32 is offset towards the conveying direction, thus forming an inclination at the input end. The guide surface 320 is used to guide the cartons. When the cartons enter from the input end, they are at a certain height from the top surface of the conveying component 2 and have a certain initial velocity. Therefore, when the cartons enter, they will first hit the guide surface 320 and then be guided to fall onto the conveying component 2 for stacking. In addition, the distance between the bottom edge of the baffle plate 32 and the top plane of the conveying component 2 only allows the stacked cartons to pass through. This allows the cartons to be stacked sequentially at certain intervals. The distance between the bottom edge of the baffle plate 32 and the top plane of the conveying component 2 can be changed by driving the air rod 33 to rotate the baffle plate 32, thereby changing the stacking spacing. Specifically, the conveying component 2 and the adsorption component 4 are provided in multiple sets. Differential conveying can be achieved between the multiple sets of conveying components 2. When the stacked cardboard passes between two sets of conveying components 2, it can be separated by differential conveying, thereby realizing the counting function.

[0028] In this embodiment, to accommodate cartons of different sizes, multiple sets of baffle assemblies 3 are provided along the conveying direction. These multiple sets of baffle assemblies 3 are arranged sequentially at intervals. When the carton is short, the baffle assembly 3 near the input end can be used to block the carton and cause it to stack. In this case, the baffle assembly 3 located at the rear adjusts the baffle plate 32 to a near-horizontal state via the drive air rod 33, or adjusts the baffle plate 32 to an angle similar to that of the baffle plate 32 used to block the carton in front. When the carton is long, the baffle assembly 3 located away from the input end can be used to block the carton. In this case, the baffle assembly 3 in front of this baffle rotates the baffle plate 32 to a near-horizontal state, while the baffle assembly 3 at the rear adjusts the baffle plate 32 to a near-horizontal state, or adjusts it to an angle similar to that of the baffle plate 32 used to block the carton in front. In addition, to avoid mutual interference between the drive air rods 33 of the multiple sets of baffle assemblies 3, the drive air rods 33 on the multiple sets of baffle assemblies 3 are alternately arranged at the left and right ends.

[0029] In this embodiment, the brush baffle 32 includes a connecting shaft 321 and a baffle 322. The connecting shaft 321 is a square shaft. The top of the baffle 322 is welded to the side of the connecting shaft 321, preferably to the side of the connecting shaft 321 near the input end. The guide surface 320 is located on the front side of the baffle 322. The two ends of the connecting shaft 321 are rotatably fitted with bearing seats 323. The brush baffle 32 is mounted on the two side support plates 31 through the bearing seats 323 at both ends.

[0030] Furthermore, since the connecting shaft 321 is a square shaft, cylindrical rotating shafts 324 extend outward from both ends of the connecting shaft 321. The connecting shaft 321 cooperates with the bearing seat 323 through the rotating shafts 324. A driving block 34 is also provided on the rotating shaft 324. One end of the driving block 34 is fixedly connected to the rotating shaft 324, and the other end is hinged to the driving end of the driving air rod 33. When the driving air rod 33 moves, it drives the rotating shaft 324 to rotate through the driving block 34, thereby causing the baffle 322 to flip.

[0031] In this embodiment, the conveying assembly 2 includes a drive shaft 21, a driven shaft 22, and a drive motor 23 rotatably mounted on the support frame 1, and a conveyor belt 24 sleeved on the drive shaft 21 and the driven shaft 22. The drive motor 23 drives the drive shaft 21 to rotate. The conveyor belt 24 is breathable and forms a conveying surface on its top. The adsorption assembly 4 includes an air suction pipe 41 mounted on the support frame 1 and an air guide pipe 42 connected to one end of the air suction pipe 41. The air suction pipe 41 is located below the conveying surface, and several positions are provided on the air suction pipe 41. At the air intake 410 below the conveying surface, the air guide pipe 42 is connected to the exhaust fan for ventilation. The exhaust fan is a conventional component and is therefore not shown in the attached drawings. During ventilation, the airflow enters the air intake 410 through the conveyor belt 24 from the conveying surface, thereby creating a negative pressure on the conveying surface. Subsequently, the airflow passes through the air intake pipe 41 and is discharged from the air guide pipe 42. During the process, the negative pressure presses the carton tightly against the conveying surface to form a limit, thereby maintaining the stable conveying of the carton and preventing the carton from being misaligned, jammed, or lifted, improving the waste removal effect of the carton and ensuring the normal operation of subsequent production processes.

[0032] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
