Description

Technical Field

[0001] The utility model relates to the technical field of product packaging equipment, in particular to a cover installation system for a push-pull lid type packaging box packaging production line and a packaging production line for the push-pull lid type packaging box. Background Art

[0002] like Figure 1 As shown, the push-pull lid packaging box is a commonly used packaging box, which is opened and closed by moving the lid and the box body towards each other. Figure 1 (shown in a) and the box cover ( Figure 1 The packaging box can be opened by pulling it in two directions (as shown in b); when closing, it is necessary to push the lid toward the box body, the box body toward the lid, or both in opposite directions at the same time. In the closed state, the flange a1 at the opening of the box body a is inserted into the side groove b1 of the box lid b, and the raised buckle on the flange a1 of the box body a is snapped into the buckle on the side groove b1 of the box lid b. During the packaging process, the flange a1 of the separated box body needs to be aligned with the side groove b1 of the box lid before the packaging box can be closed. In addition, the thickness of the box lid is only 1 to 2 mm ( Figure 1 The side height is about 5 to 6 mm ( Figure 1 Therefore, the effective surface is relatively small during packaging. Moreover, since the box cover and the box body are tightly matched, the positioning operation must be very precise. Therefore, most of the prior art uses manual packaging.

[0003] At the same time, since the box lids are not a regular structure, when placed in the box lid bin, they are not arranged regularly up and down. Therefore, after pushing out a box lid, the stacked box lids above may be stuck in the box lid bin, which will cause it to be pushed empty the next time. Utility Model Content

[0004] To solve the above problems, the utility model provides a lid-loading system for a push-pull lid packaging box packaging production line, including a lid-loading mechanism for fixing the box lid above the conveyor line and pushing the box body into the box lid to complete the packaging when the box body is conveyed to the side and bottom of the box lid.

[0005] On the basis of the above scheme, the cover-installing mechanism includes a transverse fixing part with suction cups fixed at both ends, a rotating cylinder for driving the transverse fixing part to rotate so that the suction cup rotates between a cover-sucking position for sucking up the box cover and an assembly position for assembling the box cover to the box body, and a lifting cylinder for driving the transverse fixing part to move up and down so that the suction cup at the cover-sucking position sucks the box cover and at the same time the suction cup at the assembly position carries the box cover to be assembled on the moving box body.

[0006] On the basis of the above solution, it also includes a cover pushing mechanism for pushing the box cover in the box cover bin to the cover suction position.

[0007] On the basis of the above solution, the cover pushing mechanism comprises a push plate for pushing the box cover and a push rod for driving the push plate (2-1) to perform reciprocating motion.

[0008] Based on the above solution, the thickness of the push plate is smaller than the overall thickness of the box cover.

[0009] Based on the above solution, the thickness of the push plate is one third to one half of the overall thickness of the box cover.

[0010] On the basis of the above solution, a protrusion is provided on the upper portion of the push plate for vibrating the box covers stacked in the box cover bin when the push plate moves.

[0011] Based on the above solution, the material of the raised portion is rubber.

[0012] The present application also provides a packaging production line for a push-pull lid packaging box, which includes the above-mentioned lid installation system.

[0013] The present invention relates to a lid-loading system for a production line for push-pull lid packaging boxes. This system, designed for the special-shaped structures of push-pull lid packaging boxes, ensures lid-loading accuracy and efficiency through the provision of a push plate and a raised portion, while effectively preventing the lid from falling and getting stuck in the lid compartment. The lid-loading mechanism allows the lid for the next installation to be lifted up simultaneously with the installation, preparing for the next installation and effectively improving packaging efficiency.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figure 2 As shown, the present application provides a lid-installing system for a push-pull lid type packaging box packaging production line, characterized in that it includes a lid-installing mechanism 3 for fixing the box lid above the conveyor line 10 and pushing the box body into the box lid to complete the packaging when the box body is conveyed to the side and bottom of the box lid.

[0027] Specifically, the conveyor line 10 carries the box body in continuous forward movement ( Figure 2 When the box body moves to the lower side of the box cover fixed on the cover installation mechanism 3, the flange a1 of the box body is aligned with the side groove b1 of the box cover, and the box body continues to move forward along the conveyor line 10. The flange a1 is inserted into the side groove b1 of the box cover, and the raised buckle on the flange a1 of the box body a is inserted into the buckle on the side groove b1 of the box cover b, and the cover installation process is completed.

[0028] like Figure 3 and Figure 4As shown, the cover-installing mechanism 3 includes a transverse fixing part 3-2 with suction cups 3-1 fixed at both ends, a rotating cylinder 3-3 for driving the transverse fixing part 3-2 to rotate so that the suction cup 3-1 can rotate between a cover-sucking position for sucking up the box cover and an assembly position for assembling the box cover to the box body, and a lifting cylinder 3-4 for driving the transverse fixing part 3-2 to move up and down so that the suction cup 3-1 at the cover-sucking position sucks the box cover and at the same time the suction cup 3-1 at the assembly position can be assembled with the box cover to the moving box body.

[0029] Specifically, the "cover position" refers to the position where the box cover is placed before packaging, that is, Figure 3 The position indicated by b in the middle, at this position, the suction cup 3-1 will suck up the box cover, and then the lifting cylinder 3-4 will drive it to rise, and then the rotating cylinder 3-3 will rotate 180 degrees, driving it to rotate above the conveyor line 10, that is, the assembly position ( Figure 4 position shown in a).

[0030] The function of the lifting cylinder 3-4 is to make the suction cup 3-1 at the cover suction position suck the box cover and at the same time make the suction cup 3-1 at the assembly position carry the box cover to be assembled on the moving box body. Figure 3 In the state shown, the lifting cylinder 3-4 drives the transverse fixing part 3-2 to move downward. At this time, the suction cup at the cover suction position (position b) presses down on the surface of the box cover so that the suction cup 3-1 sucks the box cover. At the same time, the suction cup 3-1 at the assembly position presses down, so that the front end of the box cover without a groove rests on the flange a1 of the box body, so that the side groove b1 of the box cover aligns with the flange a1 of the box body moving in the direction of the cover, so that the box cover is smoothly assembled on the box body. The raised buckle on the flange a1 of the box body a snaps into the snap-in on the side groove b1 of the box cover b. After assembly to the box body, the suction cup 3-1 at the assembly position is released, and the box cover and box body continue to move forward driven by the conveyor line 10, completing the cover installation action. Afterwards, the lifting cylinder 3-4 drives the transverse fixing part 3-2 upward again, raises the suction cup 3-1, and the rotating cylinder 3-3 rotates 180° to enter the next cover installation process.

[0031] Based on the above technical solution, in order to facilitate the placement of the box cover in the cover suction position, such as Figure 2 and Figure 5 As shown, the lid installation system of the present application further includes a lid pushing mechanism 2 for pushing the lids in the lid bin 1 to the lid sucking position.

[0032] Specifically, such as Figure 6 、 Figure 8 and Figure 9 As shown, the cover pushing mechanism 2 includes a push plate 2-1 for pushing the box cover and a push rod 2-2 for driving the push plate 2-1 to do reciprocating motion.

[0033] like Figure 1As shown, because the side wall thickness of the box lid is very thin, only 1 to 2 mm (the same thickness as the box lid), natural stacking is usually not able to be arranged neatly. When placing the box lid in the box lid bin 1, manual sorting will greatly reduce production efficiency. Therefore, natural stacking is usually adopted. This method can only make the overall direction of the box lid consistent, but it cannot achieve neat stacking. Therefore, the box lids will overlap each other, which reduces the effective surface of the push plate on the side of the box lid. In order to ensure that only one box lid is pushed at a time. The present application provides a specific implementation scheme of the push plate 2-1, specifically, as shown in FIG. Figure 9 As shown, the thickness of the push plate 2-1 is less than the overall thickness of the box cover. The overall thickness of the box cover refers to Figure 1 and Figure 9 Specifically, the thickness of the push plate 2-1 is one third to one half of the overall thickness of the box cover.

[0034] At the same time, since the box lids are not a regular structure, when they are placed in the box lid bin 1, they are not arranged in a regular up-down manner. Therefore, after the push plate 2-1 pushes out a box lid, the stacked box lids above may get stuck in the box lid bin 1, which will cause the box lid bin to be pushed empty the next time. In order to solve this technical problem, based on the above technical solution, as Figure 7 and Figure 8 As shown, the upper portion of the push plate 2-1 is provided with a raised portion 2-3 for vibrating the stacked lids in the lid compartment 1 when the push plate 2-1 moves. The provision of the raised portion 2-3 can generate an up-and-down vibration for the entire stacked lids when the push plate 2-1 pushes the lowest lid, thereby preventing the stacked lids from getting stuck in the lid compartment 1 and being unable to fall.

[0035] As a specific embodiment, the material of the protrusion 2-3 is rubber.

[0036] When the lid installation system is in operation, the lifting cylinder 3-4 of the lid installation mechanism 3 drives the horizontal fixing portion 3-2 to move downward. At this time, the suction cup 3-1 at the assembly position presses down, so that the edge groove of the box lid carried by the suction cup 3-1 aligns with the flange of the box body moving in the direction of the box lid, thereby smoothly assembling the box lid onto the box body. After the assembly is completed, the suction cup 3-1 at the assembly position is released, and the assembled box lid and box body are pushed forward by the stopper 1-2. Specifically, while the suction cup 3-1 at the assembly position presses down, the suction cup 3-1 at the lid suction position presses down on the surface of the box lid so that the suction cup 3-1 sucks the box lid.

[0037] When the assembly is completed, the lifting cylinder 3-4 drives the horizontal fixing part 3-2 to move upward, lifts the suction cup 3-1, and the rotating cylinder 3-3 rotates 180 degrees. At this time, the suction cup 3-1 rotated from the assembly position to the cover suction position does not carry the box cover; the suction cup 3-1 rotated from the cover suction position to the assembly position carries the box cover.

[0039] Based on the capping system in Example 1, Figure 5 As shown, the present application provides a packaging production line for a push-pull lid packaging box, wherein the production line includes the lid installation system in Example 1 and also includes an assembly line 20 for conveying products to be packaged and loading the products to be packaged into packaging boxes.
