[0002] A packaging box is a box used to package the required products. During the production and processing of the packaging box, a conveying device is required to transport it at various production and processing stages.

[0003] According to the Chinese patent announcement number CN220096830U, the patent provides a packaging box processing and conveying device, including a U-shaped seat, the tops of both ends of the U-shaped seat are fixedly connected with horizontal strips, and the bottom inside the U-shaped seat is fixedly connected with a first U-shaped block, a second U-shaped block, a third U-shaped block and a fourth U-shaped block, both ends of the first U-shaped block, the second U-shaped block, the third U-shaped block and the fourth U-shaped block are rotatably connected with connecting shafts, and a rotating adjustment frame is connected between the two connecting shafts on the first U-shaped block, the second U-shaped block, the third U-shaped block and the fourth U-shaped block. This packaging box processing and conveying device has an intermittent conveying function and can effectively perform up and down conveying operations during the intermittent conveying process, thereby effectively ensuring the stability of the packaging box processing and conveying. At the same time, this processing and conveying device has a simple structure and a stable and reliable conveying operation.

[0004] However, due to the light weight of the packaging boxes during the conveying process, they are easily affected by the vibration of the mechanical equipment and the environment when they are transported to the filling process for filling, resulting in conveying deviation and misalignment. In view of this, we propose a conveying device for packaging box processing. Utility Model Content

[0005] The purpose of the utility model is to provide a conveying device for processing packaging boxes, which solves the problem that packaging boxes are easily offset and misaligned during the conveying process.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A conveying device for processing packaging boxes comprises a workbench, a conveying mechanism is installed on the workbench, a loading plate is installed on the conveying mechanism, an up and down feeding mechanism is installed on the loading plate, the up and down feeding mechanism comprises a support plate, the support plate is fixedly connected to one side of the top of the loading plate, one side of the support plate is connected to a mounting block, a baffle is hinged on the mounting block by a latch, the end of the latch away from the baffle is connected to a connecting rod, a gear is sleeved on the connecting rod, the side of the baffle away from the latch is connected to a rotating shaft 1, the top of the support plate is connected to a rotating shaft 2, the rotating shaft 2 is connected to one end of a folding arm, and the other end of the folding arm is connected to a push rod.

[0009] Preferably, the conveying mechanism includes two linear motors, each mounted on a workbench. A mover plate is connected to the mover end of each linear motor, and the mover plate is fixedly connected to a loading plate. A tooth plate is connected to the sides of the two linear motors facing away from each other, and the sides of the two tooth plates facing toward each other are provided with teeth. The loading plate passes through the tooth plates on both sides, meshing with the teeth on the two tooth plates, causing the gears to rotate, driving the latch to rotate, and then driving the two flaps to rotate relative to each other, flipping open.

[0010] Preferably, a blocking arm is connected between the two linear motors, and a baffle is provided between the two linear motors. The baffle is in close contact with the blocking arm, and torsion springs are fixedly connected to the two linear motors on either side of the baffle. The baffle is reset under the torsion of the torsion springs. After the baffle flips 90 degrees, it is blocked by the blocking arm and does not flip further, thereby maintaining a vertical position to limit the position of the packaging boxes on the belt.

[0011] Preferably, pulleys are provided on both the first and second rotating shafts of the two loading and unloading mechanisms, and a transmission belt is connected between the first and second rotating shafts of each loading and unloading mechanism via the pulleys. The pulley on the first rotating shaft drives the pulley on the second rotating shaft to rotate via the transmission belt, thereby causing the second rotating shaft to drive the folding arm to flip synchronously.

Rotating the rotating plate pushes the limit plate toward the packaging box, limiting the position of both sides of the packaging box, and the distance between the limit plates can be adjusted according to the size of different packaging boxes.

[0013] Preferably, a conveyor belt device is provided on one side of the workbench, the conveyor belt device including legs, and guide plates are symmetrically mounted on the legs of the conveyor belt device. The symmetrical guide plates on both sides limit the conveying trajectory of the packaging boxes, thereby preventing the packaging boxes from deviating or even falling during the belt conveyor.

[0014] By means of the above technical solution, the present invention provides a conveying device for packaging box processing, which has at least the following beneficial effects:

[0015] (1) The utility model can guide the packaging boxes on the conveyor belt device to enter smoothly through the arc surface of the feeding plate and the arc surface of the limiting plate, thereby avoiding the problem of the conveyed packaging boxes getting stuck, facilitating the loading work, controlling the linear motor to work, so that the feeding plate conveys the packaging boxes for food filling, and using the limiting plates on both sides to limit the packaging boxes of different sizes, thereby improving the safety and stability of the transportation of the packaging boxes and avoiding the problem of unstable shaking during packaging filling due to the packaging box material being too light.

[0016] (2) The utility model uses a linear motor to make the feeding plate pass through the toothed plate, and utilizes the meshing rotation of the gear and the toothed plate to flip the baffle open. Under the linkage action of the pulley and the transmission belt, the baffle flips and the folding arm flips synchronously, thereby causing the push rod to flip and push the packaging box away from the feeding plate, achieving the effect of rapid unloading, simplifying the steps of manual unloading, and facilitating the delivery operation.

The two linear motors 21 are both installed on the workbench 1. The mover ends of the two linear motors 21 are connected to a mover plate 22. The mover plate 22 is fixedly connected to the loading plate 3. The two linear motors 21 are connected to a tooth plate 23 on the side away from each other, and the two tooth plates 23 are provided with teeth on the side close to each other.

Example

[0026] See also Figure 1-4On the basis of embodiment 1, the present invention provides a technical solution: preferably, there are two loading and unloading mechanisms 4, and the other loading and unloading mechanism 4 is installed on the other side of the top of the loading plate 3. The two loading and unloading mechanisms 4 are symmetrically arranged with each other, and a blocking arm 24 is connected between the two linear motors 21. A baffle 25 is arranged between the two linear motors 21, and the baffle 25 fits between the blocking arm 24. The two sides of the baffle 25 are respectively fixedly connected to the two linear motors 21 with a torsion spring. Under the torsion force of the torsion spring, the baffle 25 is reset to a vertical state. A limiting part 7 is installed on the support plate 41 in the two loading and unloading mechanisms 4, and the limiting part 7 is used to The distance is adjusted according to the size of different packaging boxes. The limiting part 7 includes a screw rod 71. The screw rod 71 threadedly passes through one of the support plates 41. One end of the screw rod 71 is connected to a rotating plate 72. The side wall of the support plate 41 fits the limiting plate 73. The side of the limiting plate 73 away from the baffle 43 is an arc structure, which is convenient for guiding the packaging boxes on the belt to enter the loading plate 3. It can be limited between the two limiting plates 73. The through end of the screw rod 71 is rotatably connected to the limiting plate 73. The two limiting parts 7 are symmetrically arranged. A conveyor belt device 8 is provided on one side of the workbench 1. The conveyor belt device 8 includes support legs, and guide plates 9 are symmetrically installed on the support legs of the conveyor belt device 8.

[0027] In this embodiment, the movable end of the linear motor 21 is controlled to drive the movable plate 22, and drives the loading plate 3 to move the contact baffle 25 to be pushed to the horizontal level, and the packaging box enters the loading plate 3 along the belt, and the rotating plate 72 pushes the limit plate 73 closer to the packaging box, limiting the two sides of the packaging box. The distance of the limit plate 73 can be adjusted according to the size of different packaging boxes, thereby ensuring the transportation stability of the packaging box after entering the loading plate 3.

[0028] Working principle: The conveyor belt device 8 belongs to the conveying equipment in the prior art, such as the DELM series belt conveyor, which uses the symmetrical guide plates 9 on both sides to limit the conveying trajectory of the packaging box, thereby avoiding the packaging box from offsetting or even falling during belt transportation. The workbench 1 in this case is aligned with the conveyor belt device 8. At the same time, according to the corresponding processing requirements of the packaging box, such as food packaging, the workbench 1 needs to be aligned with the food delivery channel at the same time to ensure that the packaging box conveyed on the loading plate 3 moves and aligns with the food delivery channel, and the food is automatically added to the inside of the packaging box.

[0029] Several packaging boxes are arranged in sequence on the belt of the conveyor device 8 for transportation. The movable end of the linear motor 21 is controlled to drive the movable plate 22 to move linearly. When the movable plate 22 drives the loading plate 3 to move and contact the baffle 25, the baffle 25 is pushed to the horizontal by the extrusion force, and the loading plate 3 covers the top of the baffle 25 and aligns with the belt of the conveyor device 8. At this time, the baffle 25 flips to the horizontal state and pushes the first packaging box back, so that the packaging box continues to move along the belt and contacts the arc surface of one side of the loading plate 3 and enters the loading plate 3. The rotating piece 72 is rotated manually to push the limit plate 73 closer to the packaging box, thereby limiting the two sides of the packaging box to ensure the stability of the conveying process and avoid the problem of unstable shaking when packaging food due to the packaging box material being too light.

[0030] The movable end of the linear motor 21 is controlled to drive the movable plate 22 away from the belt. At this time, the baffle 25 is reset under the torsion of the torsion spring. After the baffle 25 flips ninety degrees, it is blocked by the blocking arm 24 and will not flip over excessively, thereby presenting a vertical state. Its function is to limit the next packaging box on the belt to prevent multiple packaging boxes on the belt from entering the loading plate 3 at the same time. The movable plate 22 drives the loading plate 3 to move to the food delivery channel. At this time, the food is put into the packaging box on the loading plate 3 from the delivery channel for filling. After the filling is completed, the linear motor 21 continues to drive the loading plate 3 away from the food delivery channel and passes through the tooth plates 23 on both sides. At the same time, the two gears 45 respectively engage with the teeth on the two tooth plates 23, thereby generating gear 45 The rotation drives the latch to rotate, which in turn drives the two baffles 43 to rotate relative to each other and flip open, so that one side of the two support plates 41 is opened, and the rotation of the baffle 43 drives the rotating shaft 1 46 to rotate with it, so the pulley 5 on the rotating shaft 1 46 can drive the pulley 5 on the rotating shaft 2 47 to rotate using the transmission belt 6, so that the rotating shaft 2 47 drives the folding arm 48 to flip synchronously. At this time, the folding arm 48 drives the push rod 49 to enter the position between the two support plates 41, and prompts the push rod 49 to push one side of the packaging box to move toward the open position of the baffle 43, so that the packaging box filled with food leaves the loading plate 3, achieving the effect of rapid unloading, and a loading equipment such as a material transport vehicle can be placed on the side of the workbench 1 away from the conveyor belt device 8 to recycle the packaging boxes.

[0031] After the above steps are completed, the movable end of the linear motor 21 is re-controlled to drive the loading plate 3 on the movable plate 22 close to the conveyor belt device 8, and the gear 45 is reversed through the meshing of the tooth plate 23, thereby driving the two baffles 43 to flip close to each other, and closing one side of the two support plates 41. In this way, the packaging box is blocked from falling after entering the loading plate 3 from the belt. The above steps are continued to carry out the packaging box transportation and food filling work. Each packaging box can be restricted and stably transported on the loading plate 3, so as to stably fill the food and automatically and quickly unload the food, which simplifies the tedious steps of manual loading and unloading and improves the safety and stability of transporting packaging boxes.

[0032] In this case, the size of the conveying packaging box is suitable for the distance between the two push rods 49 after flipping is the minimum size of the packaging box. When the two limit plates 73 are in contact with their respective adjacent support plates 41, the distance between the two limit plates 73 is the maximum size of the packaging box. This enables the device of this case to operate stably and will not cause the push rod 49 to flip and collide with the limit plate 73 when the gear 45 passes through the tooth plate 23, causing the problem of jamming.
