For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1 and Figure 2 As shown, a cover feeding mechanism of a bag removing and cover feeding machine comprises a frame 1, a cover strip abutting device 30, a cover strip transferring device 40 and a reciprocating cover feeding device 50.

[0032] The frame 1 is provided with a cover delivery platform 11, and the cover delivery platform 11 is provided with a feed channel 11 and a discharge channel 12. The two sides of the feed end of the feed channel 11 are vertically provided with cover strip end baffles 13, and the discharge channel 12 is arranged parallel to one side of the feed channel 11. A conveying device 20 is provided on the discharge channel 12, and a cover squeezer 21 is connected to the discharge end of the discharge channel 12. The conveying belts on the conveying device 20 are two circular belts wound around the pulleys in parallel and at intervals, so that the cover strip 2 can be moved and fed on the conveying device 20 in an upright state. The conveying device 20 is also provided with a circular belt channel steel for reinforcing the upper conveying belt to prevent the upper conveying belt from sinking and deforming due to the gravity of the cover strip 2, and the belt channel steel is fixedly connected to the cover delivery platform 11.

[0033] The cover strip abutting device 30 is connected to the bottom of the cover feeding platform 11 below the feeding channel 11, and is used to abut the front end of the cover strip 2 entering the feeding channel 11, and move synchronously with the direction in which the cover strip 2 is fed in to prevent the cover strip 2 from tipping over during the feeding process.

[0034] The cover strip transfer device 40 is connected to the frame 1 and is located above one side of the feed channel 11. It is used to push against one end of the cover strip 2 that has completely entered the feed channel 11, and cooperate with the cover strip end baffle 13 to push the cover strip 2 to the discharge channel 12, so that the cover strip 2 of the removed bag can be completely sent into the discharge channel 12, and the cover strip 2 is automatically conveyed by the conveying device 20.

[0035] The reciprocating cover feeding device 50 is connected to the bottom of the cover feeding platform 11 below the discharge channel 12, and is used to continuously feed the cover strip 2 entering the conveying device 20 to the cover squeezer 21, and is used to protect the cover strip 2 from tipping over during the feeding process, so that each cover piece in the cover strip 2 is fed into the cover squeezer 21 in an upright state for piece-by-piece conveying.

[0036] like Figures 1 to 3 As shown, in this embodiment, the cover strip push-up device 30 includes a first connecting bracket 31, a first belt conveying component 32 and a top cover bracket 33. The first connecting bracket 31 is fixedly connected to the bottom of the cover feeding platform 11, and the first belt conveying component 32 is arranged on one side of the first connecting bracket 31 along the length direction of the first connecting bracket 31. The top cover bracket 33 is connected to the synchronous belt in the first belt conveying component 32 through a belt clamp. The upper end of the top cover bracket 33 vertically passes through the feed channel 11, and the upper end of the top cover bracket 33 is provided with a push rod 34 arranged toward the inlet end of the feed channel 11.

[0037] In a specific implementation, the top cover bracket 33 is connected to the synchronous belt in the first belt conveying component 32 through a belt clamp, and the push rod 34 moves on the top cover bracket 33 following the synchronous belt in the first belt conveying component 32. After the front end of the cover strip 2 enters from the feed channel 11, the first belt conveying component 32 drives the push rod 34 to push against the front end of the cover strip 2, and when the cover strip 2 continuously enters, the first belt conveying component 32 drives the push rod 34 to move synchronously with the direction in which the cover strip 2 is fed, so that the cover strip 2 of the removed bag can enter the feed channel 11 in an upright state and stay temporarily.

[0038] In this embodiment, the first connecting bracket 31 is provided with a first guide rail 35 arranged along its length direction, and the top cover bracket 33 is provided with a slider adapted to be connected to the first guide rail 35. Through the guide rail slider structure, the top cover bracket 33 can be more stable during linear movement, and the top rod 34 will not shake when moving against the front end of the top cover strip 2, thereby ensuring that the cover sheets in the cover strip 2 always remain upright and stacked together when entering the feed channel 11.

[0039] like Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the cover strip transfer device 40 includes a mounting bracket 41, a linear motor 42, a transverse slide 43 and a cover push plate 45. The mounting bracket 41 is fixedly connected to the frame 1, the linear motor 42 is transversely connected to the mounting bracket 41, the transverse slide 43 is slidably connected to the linear motor 42, the cover push plate 45 is connected to the bottom of the transverse slide 43 through a connecting shaft 44, and a telescopic end plate 46 is provided on the cover push plate 45.

[0040] The mounting bracket 41 is a frame structure, and the top of the mounting bracket 41 is fixedly connected to the frame body of the frame 1. The cross section of the cover push plate 45 is a 7-shaped, and the inner surface of the cover push plate 45 is provided with an arc groove for adapting to the shape of the cover strip 2. The telescopic end plate 46 is connected to a cylinder that is telescopic along the length direction of the cover push plate 45, so that the front end of the cover strip 2 can be pressed.

[0041] During the specific implementation, after the cover strip 2 completely enters the feed channel 11, the linear motor 42 drives the transverse slide plate 43 to drive the cover push plate 45 to move laterally, and is located above and behind the cover strip 2 in a semi-wrapped state. The telescopic end plate 46 drives to press the front end of the cover strip 2, and then the linear motor 42 drives the cover push plate 45 to move laterally to push the entire cover strip 2 into the discharge channel 12. During the entire pushing process, the rear end of the cover strip 2 is overlapped on the end baffle 13 of the cover strip, and the front end of the cover strip 2 is pressed by the telescopic end plate 46 to ensure that the cover strip 2 is upright, overlapped, and completely fed into the discharge channel 12.

[0042] In this embodiment, the cover connecting push plate 45 is connected to the transverse slide plate 43 via a connecting shaft 44 so as to be adjustable in height and can be adapted to cover strips 2 of different diameters.

[0043] like Figure 1 , Figure 2 and Figure 5 As shown, in the present embodiment, the reciprocating cover feeding device 50 includes a second connecting bracket 51, a second belt conveying component 52, a push block 53 and a vertical telescopic stop block 54. The second connecting bracket 51 is fixedly connected to the bottom of the cover feeding platform 11 and is located below the conveying device 20. The second belt conveying component 52 is arranged on one side of the second connecting bracket 51 along the length direction of the second connecting bracket 51. The push block 53 is connected to the upper synchronous belt in the second belt conveying component 52 through the first L-shaped bracket 531 and is located above the conveying device 20. The vertical telescopic stop block 54 is connected to the lower synchronous belt in the second belt conveying component 52 through the second L-shaped bracket 541. The second L-shaped bracket 541 is provided with an avoidance notch 542 for avoiding the first L-shaped bracket 531.

[0044] Among them, the vertical telescopic stopper 54 is connected to the second L-shaped bracket 541 through the telescopic cylinder 543. The telescopic cylinder 543 can allow the vertical telescopic stopper 54 to extend through the gap between the transmission belts of the conveying device 20 to block the front end of the cover strip 2 located in the discharge channel 12, and the vertical telescopic stopper 54 can also be retracted to move the cover strip 2 to release it.

[0045] In specific implementation, after the vertically stacked cover strips 2 are fed into the discharge channel 12 and are located on the circular belt of the conveyor 20, the vertical telescopic block 54 first rises to block the front end of the cover strip 2 to prevent the cover strip 2 from tipping over after contacting the moving circular belt, and the push block 53 abuts the rear end of the cover strip 2. Then the vertical telescopic block 54 is retracted to the bottom of the conveyor 20, and the push block 53 moves at the rear end of the cover strip 2 following the moving direction of the circular belt until the push block 53 moves to the limit position of the second belt conveyor component 52, and after all the cover strips 2 are fed into the cover squeezer 21, the second belt conveyor component 52 drives the push block 53 and the vertical telescopic block 54 to return to the starting position, and feeds the newly entered cover strip 2 again.

[0046] It should be noted that the first L-shaped bracket 531 and the second L-shaped bracket 541 are both connected to the upper synchronous belt and the lower synchronous belt in the second belt conveying component 52 through belt clamps, and there is a spacing distance between the first L-shaped bracket 531 and the second L-shaped bracket 541, and the spacing distance is adjustable, specifically, it can be adjusted according to the length of the cover strip 2.

[0047] The second L-shaped bracket 541 is provided with an avoidance gap 542 for avoiding the first L-shaped bracket 531 . When the first L-shaped bracket 531 and the second L-shaped bracket 541 move following the synchronous belt, they can avoid each other through the avoidance gap 542 after meeting each other, thereby avoiding structural interference caused by collision.

[0048] In this embodiment, the second connecting bracket 51 is provided with a second guide rail 511 and a third guide rail 512 arranged along the length direction thereof, the second guide rail 511 and the third guide rail 512 are arranged vertically and parallelly on the second connecting bracket 51, the first L-shaped bracket 531 is provided with a slider adapted to be connected with the second guide rail 511, and the second L-shaped bracket 541 is provided with a slider adapted to be connected with the third guide rail 512. This allows the first L-shaped bracket 531 and the second L-shaped bracket 541 to move linearly more smoothly, and prevents the push block 53 and the vertical telescopic stopper 54 from shaking during movement.

[0049] Compared with the prior art, the cover strip 2 of the removed bag is stacked and vertically stacked into the feed channel 11 through the cover strip abutting device 30 and briefly stays there. The cover strip transferring device 40 pushes and transfers the cover strip 2 staying in the feed channel 11 to the discharge channel 12. The cover strip 2 is continuously fed to the cover squeezer 21 through the conveying device 20 and the reciprocating cover feeding device 50. The cover strip 2 is separated into single cover pieces by the cover squeezer 21 and enters the next process. The entire cover feeding process of the cover strip 2 does not require manual operation, has a high degree of automation, effectively improves production efficiency, and reduces labor costs.

[0050] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
