Description

Technical Field

[0001] This utility model relates to a box-supporting device, belonging to the field of box-packing machine technology. Background Technology

[0002] A case packer is a device used to automatically or semi-automatically pack unpackaged or small-packaged products into transport packaging (such as corrugated cardboard boxes, plastic boxes, etc.). Its main functions include automatic packing, sealing, and strapping.

[0003] Before packing products into a carton, it's necessary to open the carton. This prepares the internal space, allowing the products to be placed in smoothly and without obstruction. If the carton isn't opened properly or not opened enough during packing, the products may be squeezed or impacted during placement, potentially damaging them. Therefore, to facilitate product loading, improve packing efficiency, and ensure the carton's structural integrity, one end of the carton should be opened before filling it with products.

[0004] Previously, cardboard boxes were opened manually. Carton packing machines now employ box-opening mechanisms. However, most existing box-opening mechanisms are complex, resulting in large space requirements and high manufacturing costs.

[0005] In summary, designing a new type of support box device that is simple in structure, compact in size, and reduces its manufacturing cost is an urgent technical problem to be solved. Utility Model Content

[0034] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1: As Figure 1As shown, a box-supporting device includes a door frame plate 1 and a box-supporting plate rotatably connected to one side of the door frame plate 1. The box-supporting plate includes multiple linked box-supporting plates. In this embodiment, the linked box-supporting plates include a first box-supporting plate 2, a second box-supporting plate 3, a third box-supporting plate 4, and a fourth box-supporting plate 5. The first box-supporting plate 2 and the second box-supporting plate 3 are arranged opposite each other, and the third box-supporting plate 4 and the fourth box-supporting plate 5 are arranged opposite each other. The first box-supporting plate 2, the second box-supporting plate 3, the third box-supporting plate 4, and the fourth box-supporting plate 5 can be enclosed to form a rectangular box-supporting structure. Each of the linked box-supporting plates is provided with a diagonal... The groove has a support plate protrusion 6, and each support plate protrusion 6 has a support plate moving shaft 7 in its inclined groove. The support plate moving shaft 7 passes through the inclined groove and is slidably connected to the inclined groove. At least one support cylinder 8 is also provided on one side of the door frame plate 1. In multiple linked support plates, the support plate moving shafts 7 on the support plates that move together are connected into a whole structure. The piston rod of the support cylinder 8 is connected to the support plate moving shaft 7 of the whole structure. Under the drive of the support cylinder 8, the support plate moving shaft 7 of the whole structure can move in the horizontal direction (e.g., Figure 1 The arrow in the image indicates that the support plate moves back and forth, thereby using the cooperation of the support plate's moving shaft and the inclined groove to drive multiple linked support plates to open or close. For example... Figure 2 As shown, during operation, the opening side of the carton 9 is first positioned towards the support plates, at which point the multiple support plates are in a retracted state. Then, the opening of the carton 9 is fitted onto the outer perimeter of the support plates. Next, the support cylinder 7 is activated, using the cooperation of the support plate's moving shaft and the inclined groove to rotate the support plates, thus opening the carton 9. The product is then packed from the other side of the door frame panel 1 (as indicated by the arrow in the figure). After packing, the support cylinder 7 is activated again, using the cooperation of the support plate's moving shaft and the inclined groove to rotate the support plates in the opposite direction, retracting the support plates and releasing the carton 9. The carton 9 is then removed for the next process.

[0036] This embodiment utilizes a structure where the moving shafts of the support plates engage with inclined grooves to move multiple support plates into open or retracted states, thereby expanding the carton. Its overall structure is simple, compact, and low-cost. By connecting the moving shafts of the support plates into a single unit, a linkage structure for multiple support plates is achieved, further simplifying the device structure.

[0037] like Figure 1As shown, in this embodiment, the supporting plates that operate together are a group, including supporting plate 2, supporting plate 3, supporting plate 4, and supporting plate 5. The supporting plate moving shafts 7 on supporting plate 2, supporting plate 3, supporting plate 4, and supporting plate 5 are connected to form an integral rectangular frame structure. A supporting cylinder 8 is provided on one side of the door frame plate 1. The piston rod of the supporting cylinder 8 is fixedly connected to the supporting plate moving shaft 7 of the rectangular frame structure. When the supporting cylinder 8 is activated, it drives the supporting plate moving shaft 7 of the rectangular frame structure to move, thereby using the cooperation of the supporting plate moving shaft 7 with the inclined groove of the supporting plate protrusion 6 to drive supporting plate 2, supporting plate 3, supporting plate 4, and supporting plate 5 to open or close.

[0038] It should be noted here that the supporting plates that operate together can also be set into two groups. For example, the first group of supporting plates that operate together includes supporting plate 1 2 and supporting plate 3 4, and the second group of supporting plates that operate together includes supporting plate 2 3 and supporting plate 4 5. The supporting plate moving shafts 7 of supporting plate 1 2 and supporting plate 3 4 are connected into an integral structure, and the supporting plate moving shafts 7 of supporting plate 2 3 and supporting plate 4 5 are also connected into an integral structure. Two supporting cylinders 1 8 are provided on one side of the door frame plate 1. The piston rod of the first supporting cylinder 1 8 is connected to the supporting plate moving shaft 7 of supporting plate 1 2 and supporting plate 3 4, which are connected into an integral structure, and the piston rod of the second supporting cylinder 1 8 is connected to the supporting plate moving shaft 7 of supporting plate 2 3 and supporting plate 4 5, which are connected into an integral structure. In this way, the first support cylinder 8 drives the support plate 2 and the support plate 3 4 to move, and the second support cylinder 8 drives the support plate 2 3 and the support plate 4 5 to move, thereby causing the support plates 2, 3, 4 and 5 to open or close.

[0039] like Figure 1 and Figure 3 As shown, the inclined groove 611 is a through hole, and its length direction is inclined at a certain angle to the horizontal movement direction of the support plate moving shaft 7. A roller 10 is sleeved on the support plate moving shaft 7 passing through the inclined groove 611. The roller 10 is slidably connected to the inner circumferential surface of the inclined groove 611, thereby enabling the support plate moving shaft to slide in the inclined groove. The use of a roller and sliding groove structure to achieve the sliding connection between the support plate moving shaft and the inclined groove can reduce the mutual friction and improve the service life.

[0040] In this embodiment, the roller 10 may be a bearing. To ensure the smoothness of the roller 10 during sliding, a sliding groove 6111 is also provided on the inner circumferential surface of the inclined groove 611. During operation, the roller 10 slides back and forth along the sliding groove 6111.

[0041] Multiple bearing seats 11 are also provided on the door frame plate 1. Each support box plate is provided with a support box plate pivot 12. The support box plate pivot 12 is rotatably connected to the door frame plate 1 through the bearing seat 11. A pivot connecting block 13 is also provided on the side of each support box plate. The pivot connecting block 13 is connected to the support box plate pivot 12, thereby rotatably connecting the support box plate to one side of the door frame plate 1.

[0042] like Figure 4 As shown, the carton support device also includes a carton flipping mechanism 14 disposed on one side of the carton support plate. The carton flipping mechanism 14 flips the carton 9, causing its opening to fit over the outer perimeter of the carton support plate. Since the carton exiting the carton opener faces upwards, and because the product packing process in this embodiment uses a side-push method, the carton flipping mechanism 14 must be used to flip the carton 9 9 90 degrees before fitting it over the outer perimeter of the carton support plate.

[0043] like Figure 5 and Figure 6 As shown, the carton flipping mechanism 14 includes a mounting plate 141, a translational support plate 143 slidably connected to the mounting plate 141 via a slider and a guide rail mechanism 142, and a support plate cylinder 144 disposed on the mounting plate 141. The piston rod of the support plate cylinder 144 is connected to the translational support plate 143, so that the translational support plate 143 can move back and forth in the horizontal direction under the drive of the support plate cylinder 144. A carton flipping structure is also provided on the translational support plate 143. The carton flipping structure includes a flipping tray rod 145. The carton is fixed on the flipping tray rod 145. One end of the flipping tray rod 145 is rotatably connected to the translational support plate 143 via a flipping bearing seat 146. A flipping drive mechanism is also provided on the translational support plate 143. The flipping drive mechanism is connected to the flipping tray rod 145, so that the flipping tray rod 145 can be flipped under the drive of the flipping drive mechanism.

[0044] like Figure 7 and Figure 8 As shown, during operation, the cardboard box 9 with its opening facing upwards is first fixed onto the flipping support rod 145. Then, the flipping drive mechanism 147 is controlled to rotate, causing the cardboard box 9 to rotate 90 degrees along with the flipping support rod 145, so that the opening of the cardboard box 9 faces the support plate. Next, the support plate cylinder 144 is controlled to move, causing the translation support plate 143 to move towards the support plate, thereby causing the flipping support rod 145 to move the cardboard box 9 towards the support plate, and fitting the opening of the cardboard box 9 onto the outer perimeter of the support plate. This embodiment utilizes the above structural design to realize the automatic flipping and support process of the cardboard box, further improving the intelligence level of the packing work and reducing the labor intensity of the operators.

[0045] like Figure 5 and Figure 6 As shown, the tilting tray rod 145 includes a tray rod body 1451. A rod body pivot 1452 is provided at one end of the tray rod body 1451. The pivot 1452 is connected to a tilting bearing seat 146, thereby rotatably connecting one end of the tilting tray rod 145 to the translation support plate 143. A carton baffle 1453 is also provided at one end of the tray rod body 1451, and a pressure plate cylinder 1454 is provided at the other end. A carton pressure plate 1455 is provided on the piston rod of the pressure plate cylinder 1454. In this embodiment, the carton pressure plate 1455 is U-shaped. When a carton is placed on the tray rod body 1451, the pressure plate cylinder 1454 is activated, and the carton pressure plate 1455 presses the carton onto the carton baffle 1453, thereby fixing the carton onto the tilting tray rod 145.

[0046] The flipping drive mechanism 147 includes a flipping cylinder 1471 mounted on the translation support plate 143. A rack 1472 is connected to the piston rod of the flipping cylinder 1471, and a gear 1456 is mounted on the shaft 1452 of the rod. The rack 1472 and the gear 1456 are engaged in a transmission, so that when the flipping cylinder 1471 is activated, one end of the trailer rod 1451 can be flipped around the shaft 1452.

[0047] Example 2: Compared with Example 1, the difference is that the support box plate includes not only the linked support box plate, but also the independent support box plate, such as... Figures 9 to 11As shown, in this embodiment, the linked support box plate includes support box plate 1 2, support box plate 3 4, and support box plate 4 5, and the independent support box plate includes support box plate 2 3. The support box plate 1 2 and support box plate 2 3 are arranged opposite to each other, and the support box plate 3 4 and support box plate 4 5 are arranged opposite to each other. The support box plate 1 2, support box plate 2 3, support box plate 3 4, and support box plate 4 5 can be enclosed to form a rectangular support box structure. The support box plate moving shaft 7 of the support box plate 1 2, support box plate 3 4, and support box plate 4 5 are connected into an integral structure and connected to the piston rod of the support box cylinder 1 8. The structure and rotation method of the linked support box plate are the same as those in Embodiment 1. The independent support plate, namely support plate two 3, is controlled by an independent drive mechanism. The support plate two 3 is provided with a support plate pivot two 15, and the pivot two bearing seat 17 is provided on the door frame plate 1. The support plate two 3 is rotatably connected to one side of the door frame plate 1 through the cooperation between the support plate pivot two 15 and the pivot two bearing seat 17. The independent drive mechanism includes a support cylinder two 16 provided on the door frame plate. A rack one 161 is connected to the piston rod of the support cylinder two 16. A gear one 151 is also provided at one end of the support plate pivot two 15. The rack one 161 and the gear one 151 are connected by transmission, so that when the support cylinder two 16 is activated, it can drive one end of the support plate two 3 to rotate around the support plate pivot two 15, thereby making the support plate two 3 in an open or closed state. When the box-supporting operation is performed, the linked box-supporting plates, namely box-supporting plate 1, 2, 4, and 5, are activated by box-supporting cylinder 18. The moving shaft of the box-supporting plate, in conjunction with the inclined groove, drives the opening of multiple linked box-supporting plates. Additionally, the independent box-supporting plate, namely box-supporting plate 2, is activated by box-supporting cylinder 216. The rack and pinion 161, in conjunction with gear 151, drives the independent box-supporting plate to rotate (e.g., ...). Figure 10 (As shown by the arrow in the image), this causes the independent support panels to open, thus opening the carton.

[0048] In summary, this utility model utilizes a structure where the supporting plate moving shafts and inclined grooves work together to move multiple supporting plates into open or retracted states, thereby opening the carton. Its overall structure is simple, compact, and low-cost. By connecting the supporting plate moving shafts into a single unit, a linkage structure for multiple supporting plates is achieved, further simplifying the device structure. The use of rollers and sliding grooves enables a sliding connection between the supporting plate moving shafts and the inclined grooves, reducing friction and extending service life. The designed carton flipping mechanism enables automatic carton flipping and opening, further enhancing the intelligence of the packing process and reducing the labor intensity of operators.

[0049] In this embodiment, "multiple" refers to "two or more". The above embodiments are for illustrative purposes only and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes or modifications without departing from the spirit and scope of this utility model. Therefore, all equivalent technical solutions should also fall within the protection scope of this utility model, which is defined by the claims.
