Description

Technical Field

[0001] This utility model relates to the field of packaging machinery, and in particular to an auxiliary folding device and a box gluing machine. Background Technology

[0002] like Figure 1 The packaging box shown is widely used in the pharmaceutical industry. The box has a connecting piece on its folding panel, and this connecting piece has fold lines. During the molding process, the folding panel needs to be folded backward, and the connecting piece must always remain on the same plane as the folding panel. In actual folding, due to the presence of the fold lines, the connecting piece often folds incorrectly at the fold lines, thus severely affecting molding efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide an auxiliary folding device and a box-gluing machine to solve the above problems.

[0004] An auxiliary folding device for folding a packaging box containing a connecting piece includes a first bracket, a second bracket, a support plate, a pressing fold, and a deflecting fold. One end of the support plate is fixedly connected to the first bracket, and the other end is fixedly connected to the second bracket. The pressing fold is fixedly connected to the first bracket and is located above the support plate. A first gap is provided between the pressing fold and the support plate. The deflecting fold is fixedly connected to both the first and second brackets. The pressing fold is located to the side of the support plate. A second gap is provided between the deflecting fold and the support plate. The distance between the pressing fold and the deflecting fold is greater than the width of the connecting piece.

[0005] In one embodiment, the folding portion includes a folding plate, a connecting plate, and a fixing plate that are fixedly connected.

[0006] In one embodiment, the connecting plate is trapezoidal.

[0007] In one embodiment, the lower side of the connecting plate is arranged perpendicularly to the pressure plate.

[0008] In one embodiment, the upper side of the connecting plate is perpendicular to the fixing plate.

[0009] In one embodiment, the deflection section includes an inlet plate, a deflection plate, and a tail plate that are fixedly connected in sequence.

[0010] In one embodiment, the inlet plate has an upward-facing inlet end.

[0011] In one embodiment, the deflector plate is in a twisted S-shape.

[0012] In one embodiment, the deflector plate is obtained by twisting a planar material by 180 degrees.

[0013] The aforementioned auxiliary folding device has a first gap between the pressing and folding part and the support plate, and a second gap between the support plate and the deflecting part. The distance between the pressing and folding parts is greater than or equal to the width of the connecting piece. Therefore, when the main body of the packaging box passes through the first gap and the folding plate passes through the second gap, the folding plate can be deflected by the deflecting part and ultimately fold backward, while the connecting piece, unaffected by the pressing and folding part, can deflect along with the folding plate.

[0014] A box-gluing machine includes an auxiliary folding device, wherein the auxiliary folding device is any one of the auxiliary folding devices described above. Attached Figure Description

[0024] The first bracket 10 is configured to fix the support plate 30, the pressing and folding portion 40, and the deflecting portion 50.

[0025] In this embodiment, the first bracket 10 is in a "C" shape, the pressing and folding portion 40 is fixedly connected to the upper edge of the first bracket 10, the first end of the support plate 30 is fixedly connected to the lower edge of the first bracket 10, and the first end of the deflecting portion 50 is fixedly connected to the middle position of the first bracket 10.

[0026] The second bracket 20 is configured to fix the support plate 30 and the deflecting portion 50.

[0027] In this embodiment, the second bracket 20 is in a "C" shape, the second end of the support plate 30 is fixedly connected to the upper edge of the second bracket 20, and the second end of the deflecting portion 50 is fixedly connected to the upper edge of the second bracket 20.

[0028] The support plate 30 is in a flat plate shape, one end of which is fixedly connected to the first bracket 10, and the other end of which is fixedly connected to the second bracket 20. The support plate 30 is used to support the lower surface of the packaging box. When the auxiliary folding device is disposed on the box gluing machine, the packaging box can move on the upper surface of the support plate 30 under the transmission action of the transmission mechanism of the box gluing machine. In this embodiment, the movement direction is from right to left.

[0029] The pressing and folding portion 40 is disposed above the support plate 30, and is used for pressing and folding the main body portion of the packaging box.

[0030] Specifically, please refer to Figure 3 , the pressing and folding portion 40 includes a pressing and folding plate 41, a connecting plate 42 and a fixing plate 43 which are fixedly connected from bottom to top. The pressing and folding plate 41 is arranged in a strip shape, the pressing and folding plate 41 is arranged in parallel above the support plate 30, and a first gap is provided between the pressing and folding plate 41 and the support plate 30, so that the packaging box can move in the first gap. The connecting plate 42 is used to connect the pressing and folding plate 41 and the fixing plate 43, one end of the connecting plate 42 is fixedly connected with the pressing and folding plate 41, the other end is fixedly connected with the fixing plate 43, and the fixing plate 43 is fixedly connected with the first bracket 10.

[0031] In this embodiment, the connecting plate 42 is trapezoidal, the lower side thereof is arranged perpendicular to the pressing and folding plate 41, and the upper side thereof is arranged perpendicular to the connecting plate 42.

[0032] In this embodiment, the fixing plate 43 is fixedly connected to the first bracket 10 through nuts.

[0033] The deflection portion 50 is fixedly connected to the second bracket 20, and the pressing portion 40 is located on the side of the support plate 30. A second gap is provided between the deflection portion 50 and the support plate 30, and the distance between the deflection portion 50 and the pressing portion 40 is greater than the width of the connecting piece.

[0034] Specifically, please refer to Figure 4 The deflection section 50 includes an inlet plate 51, a deflection plate 52, and a tail plate 53 fixedly connected from right to left. The inlet plate 51 has an upward-pointing inlet end 511, which is higher than the support plate 30. The deflection plate 52 is in a twisted S-shape. The tail plate 53 is flat and is fixedly connected to the second bracket 20 and is on the same plane as the support plate 30.

[0035] Please see Figure 5 As the main body of the packaging box moves forward through the first gap along with the box-gluing machine's transmission structure, the folding plate enters the second gap under the guidance of the inlet end 511, and completes a 180-degree fold under the combined action of the inlet end 511 and the deflecting plate 52. During this process, because the distance between the pressing fold 40 and the deflecting fold 50 is greater than or equal to the width of the connecting piece, the connecting piece will not contact the pressing fold 41. The connecting piece will always maintain the same direction as the folding plate. After the folding plate completes its folding, the connecting piece will connect with the folding plate and extend away from it.

[0036] In this embodiment, the deflector plate 52 is obtained by twisting a flat material by 180 degrees, giving it an S-shaped outer surface.

[0037] The aforementioned auxiliary folding device has a first gap between the pressing part 40 and the support plate 30, and a second gap between the support plate 30 and the deflecting part 50, with the distance between the pressing part 40 and the deflecting part 50 being greater than or equal to the width of the connecting piece. Therefore, when the main body of the packaging box can pass through the first gap and the folding plate passes through the second gap, the folding plate can be deflected under the action of the deflecting part 50 and eventually fold backward, while the connecting piece is not affected by the pressing part 40 and can be deflected along with the folding plate.

[0038] One embodiment of the box-gluing machine includes the above-described auxiliary folding device.

[0039] The following are specific examples.
