Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a box-pushing mechanism. Background Technology

[0002] In the crucial process of product side packaging, the formed carton needs to be flipped 90° to adjust its opening orientation to a preset position. Currently, the most common method used in the industry to meet this carton flipping requirement is manual flipping. Operators need to manually grasp the formed carton and manually complete the 90° turn adjustment. However, in large-scale production scenarios, this is labor-intensive and inefficient.

[0003] To address the problems associated with manual flipping, automated flipping solutions based on robotic arms or cylinder gripping have emerged in existing technologies. These solutions replace manual labor with mechanical structures to complete the flipping action, reducing labor intensity to some extent. However, robotic arm flipping structures require complex drive and control systems to achieve precise gripping, steering, and positioning, while cylinder gripping flipping methods require multiple sets of cylinders, linkages, and limit components to form a linkage mechanism. Both solutions suffer from high structural complexity. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a box-pushing mechanism, comprising: A first conveyor belt, one end of which is connected to a carton forming device; A box-pushing assembly, wherein the box-pushing mechanism is installed on the side of the first conveyor belt away from the carton forming equipment; The second conveyor belt is inclined as a whole. The second conveyor belt is located on the side of the first conveyor belt away from the pushing mechanism, corresponding to the pushing mechanism. The lowest end of the second conveyor belt is connected to the first conveyor belt, and the second conveyor belt is perpendicular to the first conveyor belt.

[0005] Furthermore, the pushbox assembly includes: The second power unit is fixedly installed on one side of the first conveyor belt; The pusher plate is connected to the second power unit, which drives the pusher plate to move linearly along the conveying direction perpendicular to the first conveyor belt.

[0006] A second power unit drives a pusher plate to push the carton. Utilizing the pushing force exerted by the pusher plate on the lower part of the carton, combined with the tilting characteristic of the second conveyor belt, the carton naturally tilts and flips over. This reduces the squeezing and friction on the carton caused by mechanical clamping methods, significantly minimizing the risk of deformation and damage. Compared to the complex drive and control systems required by robotic arms, and the multiple cylinders, connecting rods, and limit linkage mechanisms of pneumatic clamping methods, this invention has a simpler structure. Furthermore, the second conveyor belt connects to the first conveyor belt at its lowest point, allowing the flipped carton to directly enter subsequent packaging processes without additional transfer or positioning steps, thus improving the continuity of the packaging production line.

[0007] Furthermore, the pushing mechanism also includes guardrails, which are disposed on both sides of the first conveyor belt.

[0008] Guardrails can provide lateral restraint for cartons during transport, reducing lateral shifts, tilting, or even tipping of cartons due to conveyor belt inertia, slight equipment vibration, or external interference. They can also prevent cartons from falling off the sides of the conveyor belt during transport and while waiting to be pushed, reducing deformation and damage caused by falling cartons. In addition, they can guide the transport of cartons.

[0009] Furthermore, the guardrail includes: railing; The rollers are multiple in number and are equidistantly arranged along the length of the railing, maintaining a rotatable connection with the railing.

[0010] Multiple rollers arranged at equal intervals along the length of the railing form a continuous rolling support surface. When the carton comes into contact with the railing on the first conveyor belt due to conveying inertia or slight deviation, the rotation of the rollers can guide the carton to move in a preset direction. The rotatable rollers can convert contact friction into rolling friction, reduce the frictional resistance between the railing and the carton surface, and reduce the problems of jamming and retention between the carton and the railing.

[0011] Furthermore, the guardrail also includes: The connecting part is fixedly connected to the side of the first conveyor belt; An adjusting rod, one end of which is fixedly connected to the railing, and the other end of which passes through the connecting part and slides relative to the connecting part; A locking bolt is threaded onto the top of the connection part, and its tail end abuts against the adjusting rod to keep the adjusting rod and the connection part relatively fixed.

[0012] Loosening the locking bolts allows the adjusting rod to move the railing laterally. After adjusting to the appropriate spacing, tighten the bolts to fix it, thus improving the adaptability of the equipment.

[0013] Furthermore, the pushing mechanism also includes a blocking mechanism, which is located on the front side of the pushing assembly. There are two sets of blocking mechanisms, which are installed opposite each other on both sides of the first conveyor belt.

[0014] Furthermore, the blocking mechanism includes: A first power unit is fixedly installed on the side of the first conveyor belt; The baffle plate is connected to the first power unit, which drives the baffle plate to move linearly along the conveying direction perpendicular to the first conveyor belt.

[0015] When the second conveyor belt finishes conveying the previous carton and is ready to receive it, the blocking plate retracts to allow the next carton to enter the pushing area. If there is a brief pause in the subsequent process, the blocking plate can remain in a blocking state to temporarily store the carton, which improves the situation where the cartons accumulate and collide at the end of the first conveyor belt, or the second conveyor belt becomes overloaded and congested due to continuous pushing, thus improving the operational stability of the packaging production line.

[0016] This utility model has the following advantages: A second power unit drives a pusher plate to push the carton. Utilizing the pushing force exerted by the pusher plate on the lower part of the carton, combined with the tilting characteristic of the second conveyor belt, the carton naturally tilts and flips over. This reduces the squeezing and friction on the carton caused by mechanical clamping methods, significantly minimizing the risk of deformation and damage. Compared to the complex drive and control systems required by robotic arms, and the multiple cylinders, connecting rods, and limit linkage mechanisms of pneumatic clamping methods, this invention has a simpler structure. Furthermore, the second conveyor belt connects to the first conveyor belt at its lowest point, allowing the flipped carton to directly enter subsequent packaging processes without additional transfer or positioning steps, thus improving the continuity of the packaging production line.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0020] As described in the background section, existing technologies include automated flipping solutions based on robotic arms or cylinder gripping. These solutions replace manual labor with mechanical structures to perform flipping actions, reducing labor intensity to some extent. However, robotic arm flipping structures require complex drive and control systems to achieve precise gripping, steering, and positioning, while cylinder gripping flipping methods require multiple sets of cylinders, linkages, and limit components to form a linkage mechanism. Both solutions suffer from high structural complexity.

[0021] Example 1: Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides a box-pushing mechanism, such as... Figure 1 As shown, the box-pushing mechanism includes: A first conveyor belt 100, one end of which is connected to a carton forming equipment; A box-pushing assembly 400, the box-pushing mechanism being installed on the side of the first conveyor belt away from the carton forming equipment; The second conveyor belt 500 is inclined as a whole. The second conveyor belt is located on the side of the first conveyor belt away from the pushing mechanism, corresponding to the pushing mechanism. The lowest end of the second conveyor belt is connected to the first conveyor belt, and the second conveyor belt is perpendicular to the first conveyor belt.

[0022] For example, such as Figure 2 As shown, the pushbox assembly includes: The second power unit 410 is fixedly installed on one side of the first conveyor belt; Pusher plate 420 is connected to the second power unit, which drives the pusher plate to move linearly along the conveying direction perpendicular to the first conveyor belt.

[0023] Specifically, in this embodiment, after the carton forming equipment completes the carton forming, it directly outputs the formed carton to the first conveyor belt that is connected to it. The first conveyor belt runs horizontally in a preset direction, driving the carton to move towards the end position away from the forming equipment. When the carton reaches the preset pushing position, a second power device (such as a cylinder, electric push rod, etc.) drives a pusher plate to extend linearly along the conveying direction perpendicular to the first conveyor belt. The pusher plate contacts the side of the carton and applies a pushing force, pushing the carton laterally from the first conveyor belt to the second conveyor belt that is connected to it. The second conveyor belt runs perpendicular to the first conveyor belt and is tilted overall (its lowest end connects to the first conveyor belt). Its surface generates friction (traction) with the bottom of the carton along the conveying direction, pulling the carton along the second conveyor belt. Simultaneously, due to the tilt of the second conveyor belt, the carton's center of gravity shifts towards the lower side of the belt surface. Under the combined effect of the center of gravity torque and the traction force, the carton rotates around its bottom edge, ultimately completing a 90° turn. The carton, having completed this 90° turn, continues to be conveyed upwards on the tilted second conveyor belt, proceeding along its direction into subsequent packaging and boxing processes. This embodiment uses a second power unit to drive a pusher plate to push the carton. The pushing force exerted by the pusher plate on the lower part of the carton, combined with the tilting characteristic of the second conveyor belt, causes the carton to naturally tilt and flip, reducing the squeezing and friction on the carton caused by mechanical clamping methods and significantly reducing the risk of carton deformation and damage. Compared to the complex drive and control systems required by robotic arms, and the multiple sets of cylinders, connecting rods, and limit linkage mechanisms of cylinder clamping methods, this invention has a simpler structure. Furthermore, the second conveyor belt connects to the first conveyor belt at its lowest point, allowing the flipped carton to directly enter subsequent packaging processes without additional transfer or positioning steps, thus improving the continuity of the packaging production line.

[0024] like Figure 1 As shown, the pushing mechanism also includes guardrails 200, which are disposed on both sides of the first conveyor belt.

[0025] Guardrails can provide lateral restraint for cartons during transport, reducing lateral shifts, tilting, or even tipping of cartons due to conveyor belt inertia, slight equipment vibration, or external interference. They can also prevent cartons from falling off the sides of the conveyor belt during transport and while waiting to be pushed, reducing deformation and damage caused by falling cartons. In addition, they can guide the transport of cartons.

[0026] For example, such as Figure 4 As shown, the guardrail includes: Railing 210; Roller 220, there are multiple rollers, the multiple rollers are arranged at equal intervals along the length direction of the railing and are rotatably connected to the railing.

[0027] Multiple rollers arranged at equal intervals along the length of the railing form a continuous rolling support surface. When the carton comes into contact with the railing on the first conveyor belt due to conveying inertia or slight deviation, the rotation of the rollers can guide the carton to move in a preset direction. The rotatable rollers can convert contact friction into rolling friction, reduce the frictional resistance between the railing and the carton surface, and reduce the problems of jamming and retention between the carton and the railing.

[0028] For example, the guardrail also includes: Connecting part 230, which is fixedly connected to the side of the first conveyor belt; An adjusting rod 240, one end of which is fixedly connected to the railing, and the other end of which passes through the connecting part and slides relative to the connecting part; A locking bolt 250 is threadedly installed on the top of the connection part. The tail end of the locking bolt abuts against the adjusting rod to keep the adjusting rod and the connection part relatively fixed.

[0029] Loosening the locking bolts allows the adjusting rod to move the railing laterally. After adjusting to the appropriate spacing, tighten the bolts to fix it, thus improving the adaptability of the equipment.

[0030] In this embodiment, as Figure 1 As shown, the pushing mechanism may further include a blocking mechanism 300, which is disposed on the front side of the pushing assembly. There are two sets of the blocking mechanism, which are installed opposite to each other on both sides of the first conveyor belt.

[0031] For example, such as Figure 3 As shown, the blocking box mechanism includes: A first power unit 310 is fixedly installed on the side of the first conveyor belt; The baffle plate 320 is connected to the first power unit and is driven by the first power unit to move linearly along the conveying direction perpendicular to the first conveyor belt.

[0032] When the second conveyor belt finishes conveying the previous carton and is ready to receive it, the blocking plate retracts to allow the next carton to enter the pushing area. If there is a brief pause in the subsequent process, the blocking plate can remain in a blocking state to temporarily store the carton, which improves the situation where the cartons accumulate and collide at the end of the first conveyor belt, or the second conveyor belt becomes overloaded and congested due to continuous pushing, thus improving the operational stability of the packaging production line.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
