[0011] Beneficial effects:

[0012] During normal feeding, the lifting mechanism raises the bottom lifting plate and the tray on it to a height that matches the discharge port height of the cardboard die-cutting device (at this time, the cardboard temporary storage mechanism is located behind the tray to avoid affecting the output of the cardboard die-cutting device). The cardboard output from the die-cutting device then falls onto the tray. As cardboard is continuously output, the lifting mechanism continuously drives the lifting plate and the tray on it to descend until the maximum storage capacity of the tray is reached or the lifting plate reaches its lowest position. When a tray needs to be replaced, the control drive mechanism moves the cardboard temporary storage mechanism located behind the tray... The mechanism moves the cardboard above the pallet, where a cardboard storage mechanism temporarily stores the cardboard. After the pallet is replaced, the lifting mechanism raises the bottom lifting plate and the pallet on the lifting plate to a position that matches the height of the cardboard die-cutting device's outlet. The control drive mechanism then resets the cardboard storage mechanism, and the cardboard stored on the cardboard storage mechanism automatically falls onto the pallet, thus achieving uninterrupted feeding and die-cutting. This effectively ensures die-cutting production efficiency and overcomes the shortcomings of existing technologies, such as high labor intensity for workers, low safety factor, and reduced production efficiency of the entire die-cutting process due to pallet replacement.

[0017] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0018] like Figures 1-4As shown, a feeding mechanism for a cardboard die-cutting device includes a support mechanism 1 and a cardboard temporary storage mechanism 2. Two sets of lifting mechanisms 3 are fixed on the left and right sides of the support mechanism 1, respectively. The lifting mechanisms 3 on the left and right sides are arranged opposite to each other, and a lifting base plate 4 for supporting a tray 5 is connected between the lifting ends of the lifting mechanisms 3 on both sides. The lifting base plate 4 can move up and down under the drive of the lifting mechanisms 3. On the left and right sides of the support mechanism 1, there is also an inverted L-shaped driving mechanism 6. The vertical part of the driving mechanism 6 is located on the side of the support mechanism 1 near the discharge port of the cardboard die-cutting device, and the horizontal part of the driving mechanism 6 is located above the lifting mechanisms 3. The cardboard temporary storage mechanism 2 and the driving end of the driving mechanism 6 are fixedly connected. The cardboard temporary storage mechanism 2 can move to the top and rear of the lifting base plate 4 under the drive of the driving mechanism 6.

[0019] like Figure 1 As shown, the support mechanism 1 includes support plates 11 disposed on both sides of the outlet of the cardboard die-cutting device. The two support plates 11 are connected by multiple connecting beams 12. The cardboard temporary storage mechanism 2 is disposed between the two support plates 11.

[0020] In this example, the lifting mechanism 3 includes a lifting motor 31, a lifting gear 32, a lifting driven gear 33, and a lifting chain 34. The lifting motor 31 is fixed on the outer wall of the support mechanism 1. The lifting gear 32 is provided on the inner wall of the support mechanism 1. The output shaft of the lifting motor 31 is connected to the center of the lifting gear 32. The lifting driven gear 33 is provided on the inner wall of the support mechanism 1 below the lifting gear 32. The lifting gear 32 and the lifting driven gear 33 are connected by the lifting chain 34. A lifting fixing member 35 for connecting with the lifting base plate 4 is fixed on the lifting chain 34.

[0021] The operation of the lifting motor 31 drives the lifting gear 32 to rotate. The rotation of the lifting gear 32 drives the driven gear 33 to rotate through the lifting chain 34. In turn, the lifting fixing part 35 fixed by the lifting chain 34 drives the lifting base plate 4 to move, so as to realize continuous material feeding by lifting and lowering the pallet 5.

[0022] In this example, the drive mechanism 6 includes a drive motor 61, a drive gear 62, a first driven gear (not shown), a second driven gear 63, a third driven gear 65, and a drive chain 64. The drive motor 61 is fixed on the outer wall of the support mechanism 1, and the drive gear 62 is provided on the inner wall of the support mechanism 1. The output shaft of the drive motor 61 is connected to the center of the drive gear 62. The first driven gear is provided on the inner wall of the support mechanism 1 below the drive gear 62, the second driven gear 63 is provided on the inner wall of the support mechanism 1 in front of the drive gear 62, and the third driven gear 65 is provided on the inner wall of the support mechanism 1 to the lower left of the drive gear 62. The drive gear 62, the first driven gear, the second driven gear 63, and the third driven gear 65 are connected by the drive chain 64. The cardboard temporary storage mechanism 2 is fixed on the drive chains 64 on both sides.

[0023] The rotation of the drive motor 61 drives the drive gear 62 to rotate. The rotation of the drive gear 62 drives the first driven gear, the second driven gear 63, and the third driven gear 65 to rotate via the drive chain 64. This causes the cardboard temporary storage mechanism 2, which is fixed on the drive chain 64, to move along the L-shaped drive chain 64. As a result, the cardboard temporary storage mechanism 2 can move to the top and rear of the lifting base plate 4, realizing the temporary storage of cardboard and the unloading of cardboard after the pallet 5 is replaced.

[0024] from Figure 1 and Figure 3 It can also be seen that the cardboard temporary storage mechanism 2 includes multiple connecting rods 21 and a material support layer 22 that connects the multiple connecting rods 21 into one piece. The multiple connecting rods 21 are arranged side by side and are respectively fixedly connected to the drive chains 64 on both sides.

[0025] Driven by the drive mechanism 6, the connecting rod 21 and the material support layer 22 can move to the top of the lifting base plate 4 to temporarily store the cardboard. After the pallet 5 is replaced, they can move to the rear of the lifting base plate 4 to unload the cardboard from the cardboard storage mechanism 2 onto the pallet 5.

[0026] Preferably, the support layer 22 is made of a soft material so that it can bend at the drive gear 62 and move along the L-shaped drive chain 64.

[0027] from Figure 1 and Figure 3 It can also be seen that a baffle plate 7 is provided above the front side of the drive mechanism 6. The two ends of the baffle plate 7 are fixedly connected to the inner walls of both sides of the support mechanism 1. The baffle plate 7 can prevent the cardboard from flying out of the feeding mechanism under the power of the cardboard die-cutting device, and ensure that the cardboard can fall on the pallet or cardboard temporary storage mechanism.

[0028] It should be noted that sensors and controllers can be set up when needed to automate the entire feeding process by detecting the positions of the lifting base plate 4 and the cardboard temporary storage mechanism 6.

[0029] Working principle:

[0030] During normal feeding, the lifting mechanism raises the bottom lifting plate and the tray on it to a height that matches the discharge port height of the cardboard die-cutting device. At this time, the cardboard storage mechanism is positioned behind the tray to avoid affecting the output of the cardboard from the die-cutting device. The cardboard output from the die-cutting device then falls onto the tray. As cardboard is continuously output, the lifting mechanism continuously drives the lifting plate and the tray to descend until the maximum storage capacity of the tray is reached or the lifting plate reaches its lowest position. When a tray needs to be replaced, the control drive mechanism moves the cardboard storage mechanism located behind the tray to a position above the tray, where it temporarily stores the cardboard. After the tray replacement is complete, the lifting mechanism raises the bottom lifting plate and the tray to a height that matches the discharge port height of the die-cutting device. The control drive mechanism then resets the cardboard storage mechanism, and the cardboard temporarily stored on it automatically falls onto the tray.

[0031] Therefore, the feeding mechanism described in this embodiment realizes uninterrupted feeding and uninterrupted die-cutting, effectively ensuring die-cutting production efficiency and overcoming the shortcomings of existing technologies, such as high labor intensity for workers, low safety factor, and reduced production efficiency of the entire die-cutting process due to pallet replacement.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
