Description

Technical Field

[0001] The utility model relates to the technical field of box splitting of packaging boxes, and specifically, to a box splitting mechanism for packaging boxes. Background Art

[0002] In the small fresh fruit blister box packaging industry, before weighing and loading fruits into blister boxes, it is necessary to split the blister boxes from a stacked state. Existing box splitting devices usually use the method of inserting boxes to separate the stacked blister boxes, but the method of inserting boxes is likely to damage the blister boxes. Therefore, in the prior art, the box splitting devices have also been improved, and a vacuum suction cup device is used to suck the blister boxes.

[0003] The use of a vacuum suction cup device to suck items such as blister boxes is relatively common in the prior art. For example, a Chinese patent document with the publication number CN218751831U discloses a product instruction book conveying and placing device, which includes a conveying device and a placing device installed on a substrate. The placing device grabs the materials in the conveying device and places them at a designated position. The conveying device includes a bottom plate, a support rod spanning across the bottom plate, and a first side plate, a second side plate, and a third side plate installed on the support rod. The bottom plate, the first side plate, the second side plate, and the third side plate form a conveying channel for the materials. A limiting structure is arranged at the outlet of the material conveying channel to block the movement of the materials in the channel.

[0004] The placing device in the above patent document uses a suction cup assembly. Compared with product instruction books, the structure of the packaging box is more complex and is not a simple planar structure. The packaging box is used to hold small fresh fruits and has a certain volume. Therefore, it is more difficult to separate the stacked packaging boxes. When sucking the packaging box through the suction cup assembly, it is easy to suck two or even more packaging boxes together and it is impossible to suck a single packaging box. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a box splitting mechanism for packaging boxes, which solves the problem that in the prior art, when the packaging machine sucks the stacked blister packaging boxes, it is easy to suck two or even more packaging boxes together and it is impossible to suck a single packaging box.

[0006] To achieve the above purpose, the utility model provides a box splitting mechanism for packaging boxes, which includes a box placing device and a box taking device installed on a machine table. The box taking device takes the packaging boxes in the box placing device and transfers them to a designated position. A limiting component is arranged at the discharge port of the box placing device. The limiting component is arranged on the opposite sides of the stacked packaging boxes in a holding manner. The limiting component contacts the two sides of the packaging box. A friction structure is arranged on the contact surface between the limiting component and the packaging box. The friction structure extends towards the box taking direction and extends beyond the bottom of the stacked packaging boxes.

[0007] Further, the friction structure includes multiple levels of teeth, and the tooth surfaces of the multiple levels of teeth face the edge of the packaging box.

[0008] Further, the limiting component includes a limiting seat. A limiting arm is provided on the side of the limiting seat facing the packaging box.

[0010] Further, an adjusting device is provided at the position of the box placing device corresponding to the discharge port, and the adjusting device adjusts the distance between the limiting arms on both sides.

[0011] Further, the adjusting device includes an adjusting plate which spans across the box placing device. Adjusting long holes are provided at both ends of the adjusting plate. The limiting seat is connected to the adjusting plate through an adjusting bolt, and the adjusting bolt passes through the adjusting long hole.

[0012] Further, the box taking device includes a suction cup assembly and a transmission assembly. The suction cup assembly is connected to the machine table through the transmission assembly; a driving mechanism is installed on the machine table, and the driving mechanism drives the transmission assembly to drive the suction cup assembly to move between the position where the packaging box is located and a specified position.

[0013] Further, the suction cup assembly includes a chuck shaft fixing seat, a suction cup fixing seat, a suction pipe, and a vacuum suction cup. The suction cup fixing seat is installed on the chuck shaft fixing seat. The suction pipe is installed on the suction cup fixing seat.

[0015] Further, a plurality of chuck shaft fixing seats are installed on the rotating shaft, and the distance between the plurality of chuck shaft fixing seats is adjustable.

[0016] Further, the transmission assembly further includes a connecting rod, a rotating seat, and a rotating sleeve. One end of the connecting rod is connected to the rotating shaft, and the other end is connected in the rotating sleeve. The rotating sleeve is within the rotating seat and is rotatably connected to the rotating seat.

Detailed Embodiments

[0027] Next, the present utility model will be described in detail with reference to the drawings. What is described here is only the preferred embodiment of the present utility model. Those skilled in the art can think of other ways to implement the present utility model based on the preferred embodiment, and other ways also fall within the scope of the present utility model.

[0028] Embodiment

[0029] Please refer to Figures 1-4 , this embodiment provides a box separating mechanism for packaging boxes, which includes a box placing device 200 and a box taking device 300 installed on a machine table 100. The box taking device 300 takes the packaging boxes in the box placing device 200 and transfers them to a specified position. A limiting component 210 is arranged at the discharge port of the box placing device 200. The limiting component 210 plays a role in limiting the stacked packaging boxes, so that the packaging boxes stay at a certain fixed position, and here a certain fixed position refers to a position close to the discharge port. More specifically, the limiting components 210 are arranged on opposite sides of the stacked packaging boxes. The limiting components 210 are in contact with both sides of the packaging boxes. A friction structure is arranged on the contact surface of the limiting components 210 with the packaging boxes. The friction structure extends in the box taking direction and exceeds the bottom of the stacked packaging boxes. When the box taking device 300 takes a box, the edge of the packaging box generates friction with the friction structure, and the friction structure generates a frictional force opposite to the box taking direction. Under the action of the frictional force, the stacked packaging boxes can be separated, and a single packaging box can be taken at one time.

[0030] It should be noted that in some embodiments of the present application, such as Figure 1 and Figure 2 shown, the box placing device 200 is a hopper structure inclined downward, and the stacked packaging boxes can slide down along the hopper to the position of the limiting component 210, and the limiting component 210 positions the packaging boxes. In addition, the packaging boxes are mainly plastic blister packaging boxes, which are relatively thin as a whole.

[0031] Furthermore, the friction structure mainly provides a force in the opposite direction to the packaging box when the box taking device 300 takes a box. Considering the structure and material properties of the plastic blister packaging box, as Figure 3 shown, the friction structure includes multiple levels of teeth, and the tooth surfaces of the multiple levels of teeth face the edge of the packaging box. The material of the plastic blister packaging box itself has a certain plasticity and can deform and recover. The structure of the multiple levels of teeth enables the edge of the packaging box to pass through the obstruction of each tooth in turn and generate slight deformation when the packaging box is pulled outwards by the box taking device 300. When deforming, it is more conducive to separating two adjacent packaging boxes, further avoiding taking out multiple packaging boxes at one time. It can be understood that the so-called multiple levels of teeth refer to a structure similar to a rack formed by arranging multiple rows of teeth. In addition, in addition to adopting the structure of multiple levels of teeth, the friction structure can also adopt a comb-like or fluted structure.

[0032] In some embodiments of the present application, such as Figure 2 and Figure 3As shown, the limiting component 210 includes a limiting seat 211. A limiting arm 212 is provided on the side of the limiting seat 211 facing the packaging box. One end of the limiting arm 212 is movably connected to the limiting seat 211, and the other end is connected to the limiting seat 211 through an elastic member 214. The limiting seat 211 is provided with a groove 213, and the elastic member 214 is installed in the groove 213; the friction structure is provided on the side of the limiting arm 212 facing the packaging box. The elastic member 214 enables one end of the limiting arm 212 to converge towards the direction of the packaging box. On the one hand, it can provide better support for the packaging box; on the other hand, when the box-taking device 300 takes out the box outward, the presence of the elastic member 214 can make the limiting arm 212 float, avoiding excessive clamping of the packaging box by the two limiting arms 212 on both sides during box-taking and causing excessive deformation of the packaging box. It can be understood that the packaging box itself has a certain width. In order to provide stable clamping and limiting for the packaging box, two limiting arms 212 are arranged along the width direction of the packaging box on the limiting seat 211 to increase the support for the packaging box.

[0033] In some embodiments of the present application, as Figure 3 shown, the limiting arms 212 distributed on both sides of the packaging box are presented as a structure that gradually converges towards the box-taking direction. This design provides a gradually converging channel for the packaging box during box-taking. The edge of the packaging box undergoes a process of increasing deformation as the channel gradually converges. The edge of the packaging box is simultaneously blocked by the multi-stage tooth structure, and adjacent packaging boxes are more likely to be separated, which is beneficial to taking out a single packaging box at a time.

[0034] In actual fruit packaging work, the sizes of the packaging boxes are of different specifications. In order to enable the box-splitting mechanism to adapt to different specifications of packaging boxes, in some embodiments of the present application, as Figure 3 shown, an adjusting device is provided at the position of the discharging port corresponding to the box-placing device 200, and the adjusting device adjusts the distance between the two limiting arms 212 on both sides. Specifically, the adjusting device includes an adjusting plate 220. The adjusting plate 220 is arranged across the box-placing device 200. Adjusting long holes 222 are opened at both ends of the adjusting plate 220. The limiting seat 211 is connected to the adjusting plate 220 through an adjusting bolt 221, and the adjusting bolt 221 is arranged through the adjusting long hole 222. When adjusting the distance between the two limiting arms 212 on both sides, it is necessary to loosen the adjusting bolt 221, and then move the position of the limiting seat 211 along the length direction of the adjusting long hole 222. The limiting arm 212 moves along with the limiting seat 211. When the limiting seat 211 moves to a suitable position, tighten the adjusting bolt 221 to fix the limiting seat 211.

[0035] In some embodiments of the present application, as Figure 1As shown in the figure, the box picking device 300 includes a suction cup assembly 310 and a transmission assembly 320. The suction cup assembly 310 is connected to the machine table 100 through the transmission assembly 320. The machine table 100 is equipped with a driving mechanism, which drives the transmission assembly 320 to drive the suction cup assembly 310 to move between the position where the packaging box is located and the designated position. The suction cup assembly 310 picks up the packaging box from the position where the packaging box is located and places it at the designated position.

[0036] Specifically, as Figure 4 shown in the figure, the suction cup assembly 310 includes a chuck shaft fixing seat 311, a suction cup fixing seat 312, a suction pipe 313, and a vacuum suction cup 314. The suction cup fixing seat 312 is installed on the chuck shaft fixing seat 311. The suction pipe 313 is installed on the suction cup fixing seat 312. The vacuum suction cup 314 is connected to one end of the suction pipe 313, and the other end of the suction pipe 313 is connected to a negative pressure device. When the negative pressure device operates, the vacuum suction cup 314 generates suction force to suck the packaging box. The transmission assembly 320 includes a rotating shaft 321 and a connecting arm 322. The rotating shaft 321 is rotatably connected to the connecting arm 322. The chuck shaft fixing seat 311 is clamped on the rotating shaft 321 and fixed to the rotating shaft 321. The movement of the connecting arm 322 drives the chuck shaft fixing seat 311 to swing around the axis of the rotating shaft 321. According to the connection relationship of the vacuum suction cup 314, it can be understood that the vacuum suction cup 314 and the suction pipe 313 will swing with the chuck shaft fixing seat 311, so as to transfer the packaging box from its original position to the designated position.

[0037] It can be understood that a plurality of chuck shaft fixing seats 311 are installed on the rotating shaft 321, and the distance between the plurality of chuck shaft fixing seats 311 is adjustable. As Figure 4 shown in the figure, two chuck shaft fixing seats 311 are installed on the rotating shaft 321. When picking up packaging boxes of different sizes, the distance between the two chuck shaft fixing seats 311 can be adjusted to maintain the stability when picking up the packaging box.

[0038] Furthermore, as Figure 1 shown in the figure, in some embodiments of the present application, the transmission assembly 320 further includes a connecting rod 323, a rotating seat 324, and a rotating sleeve 325. One end of the connecting rod 323 is connected to the rotating shaft 321, and the other end is connected inside the rotating sleeve 325. The rotating sleeve 325 is inside the rotating seat 324 and is rotatably connected to the rotating seat 324. When the rotating sleeve 325 rotates, the connecting rod 323 moves linearly along the length direction of the connecting rod 323 inside the rotating sleeve 325. The length of the connecting rod 323 can limit the swinging range of the vacuum suction cup 314, and can accurately position the vacuum suction cup 314 to the position of the packaging box and convey the packaging box to the designated position.
