[0001] The invention belongs to the technical field of product packaging automation equipment, in particular to a box opening device suitable for octagonal boxes. Background Art

[0002] Octagonal box is a carton used for packing products. Compared with ordinary hexahedral carton, it has a striking decahedral structure and is a packing product with a novel appearance and structure. Since the octagonal box has a decahedral structure, the bending range between multiple side structures is relatively large, so when the octagonal box is unfolded or the folding of one side of the octagonal box is closed, the box body is easily deformed.

[0003] In addition, in the prior art, the bottom sealing operation of the octagonal box is manually performed, which not only requires the folded octagonal box to be unfolded into a three-dimensional shape, but also requires the regularity of the unfolded shape of the octagonal box to be maintained and the folding of one side of the box body with a plastic bag to be avoided when the octagonal box is in a distorted state. Such a work process has high labor intensity, low work efficiency and uneven quality. At the same time, with the automation of the subsequent packing process, manual unpacking can no longer meet the rapid production needs.

[0004] Therefore, it is very necessary to design a device that can automatically unpack octagonal boxes and improve work efficiency. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a box opening device suitable for an octagonal box, comprising: Figure 1-5 It can be seen that it includes a first conveying mechanism 1, a box holding component 2 and a tape supply component 3; two box holding components 2 are slidably installed on the first conveying mechanism, used to convey the movement of the box holding component 2 in a first direction, and the tape supply component 3 is used to seal the box on the box holding component 2.

[0028] The first conveying mechanism 1 includes a first synchronous belt 11, a first guide rail 12 and a first motor 13.

When the equipment is installed and arranged, the tape supply component 3 is installed at one end of the first conveying mechanism 1 and is distributed on both sides of the first conveying mechanism 1. The other end of the first conveying mechanism 1 relative to the tape supply component 3 is the initial position of the box holding component 2; the specific structure of the tape supply component 3 used in the present invention refers to patent CN201420679841.5.

[0030] The box holding assembly 2 is provided with a second conveying mechanism 22 and a mounting seat 23. The second conveying mechanism 22 is mounted on the mounting frame 21. The structure of the second conveying mechanism 22 is similar to that of the first conveying mechanism 1. Figure 3As shown, the second conveying mechanism 22 includes a second synchronous belt 221, a second guide rail 222 installed at the lower end of the mounting frame 21, and a second motor 223, wherein the mounting seat 23 is slidably connected to the second guide rail 222, and a clamping plate 4 is connected between the mounting seat 23 and the second synchronous belt 221, so that the second motor 223 can drive the mounting seat 23 to move in the second direction along the second guide rail 222 through the second synchronous belt 221 via the clamping plate 4, wherein the conveying directions of the first conveying mechanism 1 and the second conveying mechanism 22 are perpendicular, and a shrinking and expanding mold 24 is installed on the mounting seat 23, which cooperates with the movement of the first conveying mechanism 1 to achieve that the shrinking and expanding mold 24 can be moved in two mutually perpendicular directions.

[0031] The structure of the shrinking and expanding mold 24 is shown in the attached figure Figure 4 , 5 As shown, it includes a bottom plate, a top plate, an upper left side plate, a lower left side plate, an upper right side plate, and a lower right side plate, wherein the bottom plate and the top plate are parallel flat plate structures, a first cylinder 2401 is installed on the bottom plate, a sliding sleeve is fixed on the upper end of the bottom plate, and a guide column 2402 with one end inserted into the sliding sleeve is fixed on the lower end of the top plate, wherein the configuration combination of the sliding sleeve and the guide column 2402 is provided with four groups and distributed at the four corners of the bottom plate and the top plate; the telescopic end of the first cylinder 2401 is connected to the lower end of the top plate, so that the telescopic end of the first cylinder 2401 drives the top plate to move relative to the bottom plate; the upper left side plate is installed on one side of the top plate through a second cylinder 2403, and the upper right side plate is installed through another second cylinder 24 03 is installed on the other side of the top plate, the upper left side plate and the upper right side plate are symmetrical about the vertical center plane of the shrinkage and expansion mold, the lower left side plate is installed on one side of the bottom plate through a second cylinder 2403, and the lower right side plate is installed on the other side of the bottom plate through another second cylinder 2403; the lower left side plate and the lower right side plate are symmetrical about the vertical center plane of the shrinkage and expansion mold, in addition, the upper left side plate and the lower left side plate are symmetrical about the horizontal center plane of the shrinkage and expansion mold; the upper right side plate and the lower right side plate are symmetrical about the horizontal center plane of the shrinkage and expansion mold; the surface contours of the upper left side plate, the lower left side plate, the upper right side plate, and the lower right side plate are all curved surface structures formed by a vertical surface and a horizontal surface connected by an inclined surface, as shown in the attached figure. Figure 4 , 5 As shown, in the specific design, the curved surface structure can be formed by splicing multiple plates, or by bending the same plate. It can be seen that the structures of the upper left side panel, the lower left side panel, the upper right side panel, and the lower right side panel are the same, but the distribution and orientation are different. When working, the convex surfaces of the upper left side panel, the lower left side panel, the upper right side panel, and the lower right side panel are facing outward to support the box body; in addition, the ends of all the templates on the same side are provided with chamfers with the same slope. When working, this side is the bottom of the box body.

When the first cylinder 2401 and the second cylinder 2403 are extended, the box body sleeved on the shrinking and expanding mold 24 is stretched out to an unpacking state; in specific operation, when the box holding assembly 2 is in the initial position, the mounting seat 23 moves to both sides along the second conveying mechanism 22 to move the shrinking and expanding mold 24 in the contracted state to the position of the worker, and then the worker sleeves the box body on the shrinking and expanding mold 24. After the sleeve is completed, the first cylinder 2401 and the second cylinder 2403 are started to extend synchronously to stretch the box body to an unpacking state. After the unpacking, the folding bottom of the box body is The pages are bent to form a closed state, and at the same time, the entire box holding assembly 2 is moved to the position of the tape supply assembly 3 through the first conveying mechanism 1. During this process, the shrinking and expanding mold 24 will move inward under the action of the second conveying mechanism 22 to adapt to the position of the tape supply assembly 3. In this way, the first conveying mechanism 1 and the second conveying mechanism 22 adjust the position of the shrinking and expanding mold 24 to the position corresponding to the tape supply assembly 3, and then the bottom of the box in the open box state on the shrinking and expanding mold 24 is sealed. After the box is sealed, the box is removed. At this time, the box completes the entire unpacking process, and then the shrinking and expanding mold 24 returns to its initial state for the next unpacking.

[0033] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
