the adsorption mechanism 30 is movably arranged on the rack 10, the adsorption mechanism 30 can move towards the bending station 11 to adsorb the buckle tongue 911 of the earmuff package 90 and drive the buckle tongue 911 to move away from the bending station 11, so that the buckle tongue 911 is bent relative to the buckle plate 91 of the earmuff package 90 to form a crease.

The present invention discloses a pre-bending apparatus 100. the pre-bending apparatus 100 is used for pre-bending an earmuff package 90. The earmuff package 90 comprises a buckle plate 91, a first connecting plate 92, a base plate 93, a second connecting plate 94 and a cover plate 95 which are sequentially connected, wherein a buckle tongue 911 is formed on the buckle plate 91, and a through hole 951 for the buckle tongue 911 to pass through is formed in the cover plate 95. In the initial state of the earmuff package 90, the buckle plate 91, the first connecting plate 92, the base plate 93, the second connecting plate 94 and the cover plate 95 are disposed in a coplanar manner. The pre-bending apparatus 100 includes a frame 10, and a pressing mechanism 20 and an adsorption mechanism 30 movably disposed on the frame 10. The frame 10 is provided with a bending station 11, on which the earmuff package 90 is pre-fixed before pre-bending. During pre-bending, the pressing mechanism 20 can move towards the bending station 11 to press and fix the earcap package 90, and then the absorption mechanism 30 moves towards the bending station 11 again to absorb the buckle tongue 911 on the buckle plate 91 and drive the buckle tongue 911 to move away from the bending station 11, so that the buckle tongue 911 is bent relative to the buckle plate 91 to form a crease.

In the technical scheme of the utility model, after the buckle tongue 911 is adsorbed and moved by the adsorption mechanism 30, the buckle tongue 911 and the buckle plate 91 are not on the same plane, that is, the buckle tongue 911 is arranged in a protruding shape on the surface of the buckle plate 91, so that the buckle tongue 911 can be easily pulled up from the buckle plate 91 in the folding process of the earmuff packaging piece 90, and the buckle tongue 911 can be quickly inserted into the through hole 951 arranged on the cover plate 95 to buckle the buckle plate 91 and the cover plate 95, thereby maintaining the packaging state of the earmuff packaging piece 90. Compared with the prior art, the technical scheme of the utility model can bend the buckle tongue 911 in advance to generate a crease, thereby effectively reducing the difficulty in buckling the subsequent buckle plate 91 and the cover plate 95, improving the buckling efficiency of the buckle plate 91 and the cover plate 95 in the folding process of the earcap package 90, and simultaneously improving the assembling efficiency of the earcap and the earcap package 90.

The frame 10 may be a plate structure or a frame structure, and the frame 10 provides a mounting carrier for the pressing mechanism 20, the suction mechanism 30, and other control components. The frame 10 may be secured directly to the base and the bending station 11 on the frame 10 refers to the area where the earmuff package 90 is pre-bent. That is, all areas of the pre-bending process for the earmuff package 90 in this embodiment can be referred to as bending stations 11.

It should be understood that the initial state of the ear muff package 90 may be pre-fixed on the bending station 11 directly, or pre-fixed on the bending station 11 by a carrier (not shown), where the carrier is a positioning fixture for precisely fixing the ear muff package 90, and the ear muff package 90 is fixed on the carrier before entering the pre-bending process, and the carrier may fix and position the ear muff package 90. Therefore, when the ear muff package piece is transported by the transport mechanism 60, the automatic transport of the ear muff package piece 90 can be realized only by matching the carrier with the transport mechanism 60, and the ear muff package piece 90 can keep the characteristics of smooth transport, high transport positioning precision and the like in the automatic transport process by using the carrier. By using the carrier, the earmuff package 90 can be accurately fixed at the preset position, so that the pressing mechanism 20 can be accurately pressed on the surface of the earmuff package 90, the adsorption mechanism 30 can accurately adsorb the pressing plate to form the buckle tongue 911 area, only the buckle tongue 911 is adsorbed, the area outside the buckle tongue 911 is not adsorbed, and the pre-bending precision of the earmuff package 90 is improved.

It should be noted that the position of the suction mechanism 30 in this embodiment may be below the bending station 11, or above the bending station 11, and the direction of the earmuff package 90 may be adjusted according to the installation position of the suction mechanism 30. For example, when the suction mechanism 30 is located below the bending station 11, the inner surface of the ear muff packing member 90 (the inner surface of the accommodating space 96) is arranged upward; if the suction mechanism 30 is located below the bending station 11, the inner surface of the ear muff packing member 90 (the inner surface of the receiving space 96) is disposed downward. Of course, the suction mechanism 30 may also be located at a side of the bending station 11, and at this time, after the buckle plate 91 of the earmuff package 90 needs to be folded, the buckle plate 91 is folded to a plane opposite to the suction mechanism 30.

It can be understood that, as long as the buckle tongue 911 formed on the buckle plate 91 is bent to be not in the same plane as the buckle plate 91, the buckle tongue 911 can form a crease relative to the buckle plate 91, which also corresponds to the completion of the pre-bending process of the earcap package 90, as shown in fig. 8, fig. 8 is a schematic diagram of the earcap package 90 after only pre-bending the buckle tongue 911.

Of course, the pre-bending of the ear muff package 90 can also be performed simultaneously for other parts than the pre-bending tongue 911. For example, pre-bending of the earmuff package 90 may also pre-bend the buckle tongue 911, the buckle plate 91 and the cover 95 at the same time. Fig. 9 is a schematic view of the earmuff package 90 after pre-bending the rebate tongue 911, gusset 91 and cover 95, as shown in fig. 9.

The conveying mechanism 50 includes two guide rails 51 and a conveying driving assembly 53, wherein the two guide rails 51 are disposed at an interval on the frame 10, the two guide rails 51 are disposed opposite to each other, and a conveying space (not shown) is formed between the two guide rails 51. The guide rail 51 extends along the longitudinal direction of the frame 10, and the bending station 11 is located between both ends of the guide rail 51 in the longitudinal direction. And the transmission driving assembly 53, the transmission driving assembly 53 is arranged in the transmission space, and the transmission driving assembly 53 provides a power source for the automatic transmission of the earmuff package 90. The two guide rails 51 can limit the position of the earmuff package 90 in the conveying process, so that the earmuff package 90 can be tidy and orderly in the automatic conveying process. The transfer driving unit 53 may be of various types, such as a belt transfer type, a chain transfer type, a transfer roller set type, and the like.

In one embodiment, when the conveying driving assembly 53 is in a belt conveying manner, the conveying driving assembly 53 includes a driving motor 531, a set of pulleys 533, and a belt 535, wherein the driving motor 531 is in transmission connection with the set of pulleys 533, and the belt 535 is sleeved on a surface of the set of pulleys 533. The earmuff package 90 is placed on the surface of the belt wheel 533, the driving motor 531 drives the belt 535 to rotate through the belt wheel 533 group, and the belt 535 rotates to drive the earmuff package 90 placed on the surface of the belt wheel 533 to automatically convey, so that the conveying efficiency is improved.

Further, referring to fig. 1 to fig. 3, in an embodiment of the present invention, the pre-bending apparatus 100 further includes two guiding members 60, one guiding member 60 is connected to one guiding rail 51, the guiding member 60 is disposed obliquely along a conveying direction of the conveying mechanism 50, and the ear muff package 90 is conveyed to the bending station 11 along the oblique direction of the two guiding members 60.

In the solution of an embodiment of the present invention, the guiding element 60 is a plate-shaped structure, and the two guiding elements 60 are respectively connected to the two guide rails 51 for guiding the ear muff package 90 automatically conveyed by the conveying mechanism 50 to guide the ear muff package 90 to a predetermined position. The guide plate is inclined in the conveying direction of the conveying mechanism 50, meaning that the distance of the guide 60 from the conveyor belt gradually increases in the conveying direction so that one end of the guide 60 is flush with the belt 353 and the other end is positioned higher than the belt 353. Therefore, the guide piece 60 can guide the earmuff package piece 90 to the upper part of the transmission and adsorption mechanism 30, when the pressing mechanism 20 moves towards the bending station 11 and drives the first connecting plate 92, the base plate 93 and the second connecting plate 94 to move continuously towards the transmission mechanism, at the moment, the buckle plate 91 and the cover plate 95 can be turned over relative to the base plate 93, so that the buckle plate 91 and the cover plate 95 are both turned over to be perpendicular to the base plate 93, the buckle plate 91 and the adsorption mechanism 30 located on the side edge of the bending station 11 are arranged oppositely, the adsorption mechanism 30 can adsorb the buckle tongue 911 by moving towards the bending station 11, and drives the buckle tongue 911 to move relative to the buckle plate 91, so that the buckle tongue 911 is bent relative to the buckle plate 91 and forms a crease mark. After the buckle tongue 911 is bent relative to the buckle plate 91 and a crease is formed, the buckle tongue 911 and the buckle plate 91 are not coplanar any more, the buckle tongue 911 is arranged at an included angle relative to the buckle plate 91 at the moment, and after the absorption mechanism 30 releases the buckle tongue 911, the buckle tongue 911 can not be restored to the state of being coplanar with the buckle plate 91 even if reset to a certain degree occurs, so that the buckle tongue 911 can be quickly pulled up in the subsequent folding and packaging process, the buckling operation is completed, and the packaging efficiency is improved.

In the solution of an embodiment of the present invention, after the absorption mechanism 30 releases the buckle tongue 911, the overlaying mechanism 20 also moves away from the bending station 11, and the earcap package 90 after bending process can be automatically conveyed to the next station along the belt conveying mechanism 50 for folding process.

Referring to fig. 1 and 4, in an embodiment of the present invention, the pressing mechanism 20 moves toward the bending station 11, the pressing mechanism 20 abuts against the ear muff package 90 and drives the first connecting plate 92, the base plate 93 and the second connecting plate 94 of the ear muff package 90 to move, so that the buckle plate 91 and the cover plate 95 of the ear muff package 90 are folded relative to the base plate 93;

the adsorption mechanism 30 is arranged on one side of the transmission mechanism 50, and the adsorption mechanism 30 moves towards the folded buckle plate 91 to adsorb the buckle tongue 911 formed on the buckle plate 91 of the earcap package 90.

In the technical solution of an embodiment of the present invention, the pressing mechanism 20 is used for pressing and fixing the earcap package 90, and can also be operated by turning over a part of the structure of the earcap package 90. For example, the earmuff package 90 is guided to a position above the transport mechanism 50 by the guide 60. Because the ear muff package 90 is higher than the transmission mechanism 50, when the pressing mechanism 20 moves towards the bending station 11 and abuts against the ear muff package 90, the pressing mechanism can still move downwards, and at the moment, the edges of the two guide pieces 60 abut against the pressing plate and the cover plate 95 respectively, so that the buckling plate 91 and the cover plate 95 are arranged in a turnover mode relative to the base plate 93.

It will be appreciated that in other embodiments, the operation of the capping mechanism 20 to fold the gusset 91 and cover 95 relative to the base 93 may be accomplished without the guide 60. For example, in the conveying space formed by the conveying mechanism 50, the bottom is hollowed out, when the pressing mechanism 20 moves towards the bending station 11 and abuts against the earcap package 90, the pressing mechanism can also continue to move downwards, and at this time, the inner walls of the two guide rails 51 can abut against the pressing plate and the cover plate 95 respectively, so that the buckling plate 91 and the cover plate 95 can be turned over relative to the base plate 93.
