Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, and in particular to a cardboard box flipping machine with a limiting structure. Background Art

[0002] Cardboard boxes are the most widely used packaging products, and there are many different types. Cardboard boxes need to be turned over before transportation. During the turning process, the structure and sealing of the box can be checked, as well as the packaging of the goods, to ensure the rationality and stability of the goods packaging. Therefore, a cardboard box turning machine with a limiting structure is used.

[0003] To address this, patent CN220363978U discloses a hydraulic tilting machine with a limiting mechanism. The machine includes a support box with a hydraulic rod movably mounted inside, and the output shaft of the hydraulic rod connected to a support platform. It comprises: a fixed plate fixed to the edge of the support platform, with a first fixing block fixed to its side and a fixing hole pre-drilled on the fixed plate above the first fixing block; a movable plate movably disposed on top of the fixed plate, with a second fixing block fixed to its side and a limiting rod passing through the interior of the second fixing block; and a traction rope, one end of which is fixedly connected to the other edge of the support platform, with a piston block connected to its bottom and a fixing cylinder sleeved on the outside of the piston block. This hydraulic tilting machine with a limiting mechanism is designed for roller-shaped objects, preventing them from rolling and falling after placement or during tilting, and limiting the object's position to ensure stability during tilting.

[0004] While the hydraulic tilting machine with a limiting mechanism mentioned above can prevent items from rolling and falling after being placed or during the tilting process, its inconvenience in adjusting its position and its unsuitability for cartons of different heights make it less applicable in use. Utility Model Content

[0005] The purpose of this invention is to provide a carton flipping machine with a limiting structure to solve the problem that existing carton flipping machines with limiting structures are inconvenient to adjust the position.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a carton flipping machine with a limiting structure, including a frame and a support plate;

[0007] The top of the frame is provided with a conveying assembly, and support plates are fixed on both sides of the top of the frame. A sliding rod is fixed on the top of each support plate. A limiting mechanism is sleeved on the outside of each sliding rod. The limiting mechanism includes a limiting seat, a movable groove, a return spring, a pull ring, a connecting rod, a locking block, and a locking groove.

[0008] The outer side of the top slide bar of the limiting mechanism is fitted with a flipping structure;

[0009] Guide structures are provided on both sides of the top of the frame.

[0010] When using this device, the setting of a limit mechanism enables the device to be easily adjusted in height, thereby improving the applicability of the carton flipping machine with the limit structure during use; the setting of a guide structure enables the device to be easily guided, thereby improving the stability of the carton flipping machine with the limit structure during use; and the setting of a flipping structure enables the device to be easily flipped, thereby improving the convenience of the carton flipping machine with the limit structure during use.

[0011] Preferably, the conveying assembly includes a first conveying roller, a conveyor belt, a support roller, a second conveying roller, and a drive motor. The conveyor belt is disposed on the top of the frame, and the support rollers are evenly distributed through the top of the conveyor belt. The first conveying roller passes through one end of the conveyor belt, and the second conveying roller passes through the other end of the conveyor belt. The drive motor is fixed to the outer wall of the frame at one end of the first conveying roller. When the drive motor is started, it drives the first conveying roller to rotate inside the frame. The first conveying roller, through the conveyor belt, drives the support roller and the second conveying roller to rotate.

[0012] Preferably, one end of the first conveyor roller extends to the outside of the frame and is fixedly connected to the output end of the drive motor, while both ends of the support roller and the second conveyor roller extend into the inside of the frame and form a rotating structure with the frame. The carton is placed at the top of the conveyor belt, which then transports the carton. Supported by the support roller, this design is suitable for cartons of varying weights.

[0013] Preferably, the guiding structure includes a vertical plate, an electric push rod, guide rods, a fixed frame, and guide rollers. The vertical plate is fixed to both sides of the top of the frame. An electric push rod runs through the interior of each vertical plate, and a fixed frame is fixed to one end of each electric push rod. Guide rollers are evenly installed on one side of the fixed frame, and guide rods run through the interior of the vertical plates on both sides of the electric push rod. When the electric push rod is activated, it moves the fixed frame, which in turn moves the guide rods within the vertical plate. The guide rods enhance the stability of the fixed frame during movement, and the fixed frame moves the guide rollers to one side of the box.

[0014] Preferably, the guide rod and the vertical plate form a sliding structure, one end of the guide rod is fixedly connected to one side of the fixed frame, and both ends of the guide roller extend into the interior of the fixed frame and form a rotating structure with the fixed frame. Under the action of the fixed frame, the carton can be ensured to maintain the correct path during conveying, preventing conveying obstruction or damage caused by deviation. Under the action of the guide roller, the friction between the fixed frame and the carton is reduced.

[0015] Preferably, the flipping structure includes a slide, a fixing plate, and a fixing rod. The slide is sleeved on the outside of the top slide rod of the limiting seat. A fixing plate is fixed on one side of the slide, and a fixing rod is fixed between adjacent fixing plates.

[0016] Preferably, the slide block and the slide rod form a sliding structure, with the bottom end of the slide block abutting against the top end of the limiting seat. When the carton moves to one side of the fixed rod via the conveyor belt, under the action of the fixed rod, the carton moves the slide block outside the slide rod via the fixed rod, causing the carton to flip. After the carton flips, the slide block moves downward to return to its original position.

[0017] Preferably, the limiting seat is sleeved on the outside of the slide rod. The slide rod has evenly spaced locking grooves on both sides inside. The limiting seat has movable grooves on both sides inside. Each movable groove contains a locking block, one end of which is fixed with a connecting rod. One end of each connecting rod extends to the outside of the limiting seat and is fixed with a pull ring. A return spring is sleeved on the outside of the connecting rod inside the movable groove. Pulling the limiting seat upwards moves the locking block into the movable groove. Under the elastic force of the return spring, the connecting rod pushes the locking block into the locking groove, thus fixing the limiting seat and the slide rod together. Pulling the pull ring moves the locking block to the outside of the locking groove via the connecting rod.

[0018] Preferably, the limiting seat and the slide rod form a sliding structure, and the locking block and the slide rod form an engaging structure through locking grooves. This allows the limiting seat to move up and down on the outside of the slide rod. Under the limiting action of the limiting seat, the height of the fixing rod can be adjusted. The locking block, in conjunction with different locking grooves, can be used to flip boxes of different heights.

[0019] The advantages of the carton turning machine with a limiting structure provided by this utility model are as follows:

[0020] By setting a limiting mechanism, pulling the limiting seat upwards moves the locking block into the interior of the movable groove. Under the elastic force of the return spring, the connecting rod pushes the locking block into the interior of the locking groove, thereby fixing the limiting seat and the sliding rod together. Pulling the pull ring moves the locking block to the outside of the locking groove through the connecting rod, causing the limiting seat to move up and down on the outside of the sliding rod. Under the limiting action of the limiting seat, the height of the fixing rod can be adjusted. By cooperating with different locking grooves, the locking block can be used to flip boxes of different heights, realizing the function of easy height adjustment of the device, thereby improving the applicability of the carton flipping machine with the limiting structure in use.

[0021] By incorporating a guide structure, the electric push rod is activated, which moves the fixed frame. The fixed frame then moves the guide rod inside the vertical plate, enhancing the stability of the fixed frame during movement. The fixed frame moves the guide roller to one side of the carton, ensuring that the carton maintains the correct path during transport and preventing conveying obstruction or damage due to deviation. The guide roller reduces the friction between the fixed frame and the carton, facilitating guidance and improving the stability of the carton flipping machine with a limiting structure during use.

[0022] By incorporating a flipping structure, when a carton is moved to one side of a fixed rod via a conveyor belt, the fixed rod causes the carton to move along the outside of the slide block, thus flipping the carton. After the carton flips, the slide block moves downwards to return to its original position, thereby enabling the device to easily flip and improving the convenience of using the carton flipping machine with a limiting structure.
