[0037] In order to illustrate the technical content and structural features of the present application, the following further describes the present application in conjunction with the embodiments and the accompanying drawings.

[0038] Referring to Figure 1 and Figure 2 , the present application provides a card stack feeding device 100, which is suitable for feeding and conveying of card paper in the production of paper bags, cartons and the like. The card stack feeding device 100 comprises a support frame 101, a stacking mechanism 10, a taking mechanism 20, a feeding mechanism 30 and a buffer feeding mechanism 40 arranged on the support frame 101. The stacking mechanism 10 comprises a rack 11 for placing card paper, and the rack 11 is arranged on the support frame 101 at a preset angle so that the card paper stacked in the rack 11 is always inclined towards the discharge port 113 of the rack 11 for easy discharge. That is, the discharge bottom surface 112 of the rack 11 for placing card paper is gradually inclined downward from the tail end towards the direction of the discharge port 113, so that the stacked card paper can be automatically discharged close to the discharge port 113 under the action of its own gravity after being taken. Illustratively, the inclination angle can be any angle between 10 degrees and 80 degrees, and preferably, the preset angle can be 30 degrees. A rolling assembly 13 and a distributing assembly 12 are arranged on the rack 11, the rolling assembly 13 is used to support the card paper and can assist in feeding, and the weight of the stacked card paper is supported by a plurality of rolling assemblies 13 to facilitate easy discharge. The rolling assembly 13 can limit and support the card paper, and can effectively bear the weight of the card paper. The part of the card stack in contact with the rolling assembly 13 can be arched to play a role in separating the card paper. The distributing assembly 12 is used for distributing the card paper to prevent double feeding. The taking mechanism 20 is used to pick up a single card paper in the rack 11 and place it on the feeding mechanism 30. The feeding mechanism 30 comprises a linkage push assembly 32 and a conveying assembly 34, the push assembly 32 cooperates with the taking mechanism 20 to convey the card paper into the conveying assembly 34. The conveying assembly 34 conveys the card paper along a preset track to make the card paper located in the buffer feeding mechanism 40, and the buffer feeding mechanism 40 acts to feed the card paper into the workpiece. It can be understood that the preset track is a track along the conveying channel 345 to guide the card paper from the conveying belt 324 of the push assembly 32 into the conveying section 402 of the buffer feeding mechanism 40.

[0039] Referring to Figures 3 to 5In some optional embodiments, the material rack 11 is in an L-shaped structure, the rear end frame is lower to facilitate placing of the material, and the front end frame is higher to guide the stacked cards well. The placing bottom surface 112 of the material rack 11 for placing the cards is gradually inclined downward from the tail end to the discharge port 113, so that the stacked cards can be automatically close to the discharge port 113 after being taken out. A material positioning member 111 is further arranged at the tail end of the material rack 11. The arrangement of the material positioning member 111 can position the stacked cards in the material rack 11, so that the cards are more stable in the material rack 11 and are not displaced. The two ends of the material rack 11 are further provided with an adjusting assembly 15. The width of the material rack 11 is adjusted by the adjusting assembly 15, so that the material rack 11 can be suitable for cards of various specifications. A locking member 151 is further arranged on the adjusting assembly 15. When the material rack 11 is adjusted to the appropriate width, the material rack 11 is locked by the locking member 151, which is convenient to operate and has a wide range of applications.

[0040] Please refer to Figures 3 to 5 In some optional embodiments, the discharge port 113 is arranged on the end surface of the material rack 11 close to the taking mechanism 20, and the discharge port 113 is surrounded by the rolling assembly 13 and the material separating assembly 12. Since the discharge port 113 supports and limits the stacked cards by the multiple sets of rolling assemblies 13, when the taking mechanism 20 picks up the cards, the cards roll and rub against the rolling assembly 13, so that the cards can be discharged better and more conveniently, and the cards can be prevented from being scratched. The rolling assembly 13 can also assist in separating the cards, and the structure design is reasonable. Specifically, each set of rolling assembly 13 is provided with a rotatable roller 131. When the taking mechanism 20 picks up the single card closest to the discharge port 113, the roller 131 rolls in contact with the card. The rotation of the roller 131 can assist in pushing the card and can prevent the card from being damaged. For example, the roller 131 can be a bearing. The bearing can prevent the card from being pushed out of the material rack 11 under its own gravity, can limit and support the card, and can effectively bear the card stack. The part of the card stack in contact with the bearing can be arched under the action of the bearing surface to separate the cards. Each set of material separating assembly 12 includes a material separating paddle 121 adjustably arranged on the material rack 11. The material separating paddle 121 can be a steel sheet with elasticity. According to the different sizes of the cards, the installation position of the material separating paddle 121 can be adjusted by the adjusting part 122 on the material separating paddle 121 to adapt to cards of different specifications. When the taking mechanism 20 picks up the card closest to the discharge port 113, the material separating paddle 121 can scrape the card to prevent double picking. The material separating paddle 121 can be reset by its own elasticity after scraping. On the other hand, a plurality of guide blocks 14 are further arranged on both sides of the discharge port 113. The guide blocks 14 can guide the cards in the material rack 11 to the pushing assembly 32. The guide blocks 14 can prevent the cards from being displaced.

[0041] Please refer to Figure 2 , Figures 6 to 8In some optional embodiments, the feeding mechanism 30 comprises a mounting plate 31 arranged on the support frame 101, the mounting plate 31 being parallel to the discharge port 113 of the magazine 11. A plurality of through slots 311 for taking out the card are formed in the mounting plate 31. The taking-out mechanism 20 comprises a taking-out motor 21 and a taking-out assembly 22 arranged at the output end of the taking-out motor 21, and a plurality of taking-out suction cups 221 are arranged on the taking-out assembly 22. The taking-out motor 21 is actuated to make the taking-out suction cups 221 pick up the card in the magazine 11 through the through slots 311, and then the taking-out motor 21 drives the taking-out suction cups 221 to reset, so that the card on the taking-out suction cups 221 is arranged on the pushing assembly 32. It can be understood that, in the starting position, the taking-out suction cups 221 are located in the through slots 311 to be well guided to take out the card. The suction surface of the taking-out suction cups 221 is retracted into the through slots 311, so that the card can be automatically separated from the taking-out suction cups 221 after the taking-out suction cups 221 pick up the card and reset, and the card is adsorbed on the pushing assembly 32. In some embodiments, the card in the card stack is discharged by the belt friction, and when the thickness of the card is different, the card is easy to be jammed. In addition, the convex points on the belt are easy to be ground flat after long time friction with the card, and the paper fibers on the card can fill the concave points on the belt, thereby reducing the friction of the belt and affecting the feeding of the belt. In the present embodiment, the taking-out assembly 22 is used for suction taking-out, which not only can reduce the friction on the conveying belt 324, but also can pick up cards of various thicknesses without adjustment, and the feeding effect is good.

[0042] Please refer to Figures 7 to 9In some optional embodiments, the pushing assembly 32 is arranged on the mounting plate 31, and the pushing assembly 32 comprises a fixing member 321 arranged on the mounting plate 31, both ends of the fixing member 321 are provided with rotatable rotating members 322. A conveying belt 324 is sleeved on the fixing member 321 and the rotating member 322, and the rotating member 322 rotates to drive the conveying belt 324 to convey the card paper. Specifically, one rotating member 322 is provided with a transmission shaft 323 connected to the first power assembly 36, and the first power assembly 36 drives the transmission shaft 323 to rotate the rotating member 322, thereby driving the conveying belt 324 to convey. Specifically, the fixing member 321 has a hollow structure, and the hollow fixing member 321 is connected with the air suction assembly 33. The surface of the conveying belt 324 is provided with a plurality of through holes 3241, and the air suction assembly 33 is used to enable the fixing member 321 to adsorb the card paper on the conveying belt 324 through the through holes 3241. It can be understood that after the material suction cup 221 picks up the card paper and returns to the through slot 311, the card paper is arranged on the pushing assembly 32, and the air suction assembly 33 drives the pushing assembly 32 to adsorb the card paper. Since the fixing member 321 has a hollow structure, and the end face close to the discharge port 113 has an open structure, and the conveying belt 324 is arranged around the fixing member 321, and a plurality of through holes 3241 are also arranged on the conveying belt 324. The air suction assembly 33 drives the fixing member 321 to ventilate and adsorb the card paper through the through holes 3241 on the conveying belt 324, so that the card paper is more stably adsorbed on the conveying belt 324 for conveying. In this embodiment, the card paper is adsorbed on the conveying belt 324 by the air suction assembly 33, and the card paper and the conveying belt 324 are relatively stationary, and the conveying belt 324 drives the card paper to move forward. That is, the relative friction between the card paper and the conveying belt 324 is small, which can avoid damaging the card paper due to the mutual friction between the card paper and the conveying belt 324, and can avoid that the paper fibers on the card paper fill the through holes 3241 on the conveying belt 324. The structure design is reasonable.

[0043] Please refer to Figures 7 to 9 In some optional embodiments, the feeding mechanism 30 further comprises a first power assembly 36 connected to the pushing assembly 32 and the conveying assembly 34, and the first power assembly 36 is installed on the support frame 101. The first power assembly 36 drives the pushing assembly 32 and the conveying assembly 34 to convey synchronously. Specifically, the first power assembly 36 comprises a conveying motor 361 and a synchronous transmission assembly 362 located at the output end of the conveying motor 361, and the pushing assembly 32 and the conveying assembly 34 are connected to the synchronous transmission assembly 362 for synchronous conveying. The synchronous transmission assembly 362 comprises gears, synchronous pulleys, synchronous belts and the like. It can be understood that the pushing assembly 32 drives the card paper to be pushed into the conveying assembly 34, and the card paper is conveyed into the buffer and delivery mechanism 40 through the conveying assembly 34.

[0044] Please refer to Figure 9 and Figure 10In some optional embodiments, the conveying assembly 34 comprises a first conveying roller 341, a second conveying roller 342 and a third conveying roller 343. A guide 344 is arranged between the second conveying roller 342 and the third conveying roller 343, and the second conveying roller 342, the third conveying roller 343 and the guide 344 are arranged on one side of the first conveying roller 341 to form an arc-shaped conveying passage 345 with the first conveying roller 341, and the card paper is conveyed to the buffer delivery mechanism 40 through the conveying passage 345 on the pushing assembly 32. It can be understood that the diameter of the first conveying roller 341 is larger than the diameters of the second conveying roller 342 and the third conveying roller 343, and the guide 344 is provided with an arc-shaped surface 3441 matched with the first conveying roller 341, and the arc-shaped surface 3441 constitutes part of the conveying passage 345. The first conveying roller 341 is further provided with a position-avoiding part 3411 matched with the material distribution assembly 12 at the bottom of the material rack 11, and the position-avoiding part 3411 can avoid interference between the first conveying roller 341 and the material distribution assembly 12. The first power assembly 36 drives the first conveying roller 341, the second conveying roller 342 and the third conveying roller 343 to rotate simultaneously to convey the card paper in the conveying passage 345.

[0045] Please refer to Figure 9 In some optional embodiments, the two ends of the first conveying roller 341 and the second conveying roller 342 are provided with elastic pushing assemblies 35, which can enhance the friction between the card paper and the conveying passage 345 to facilitate the conveying of the card paper in the conveying passage 345. It can be understood that if the width of the conveying passage 345 is too large, the outer wall of the first conveying roller 341, the second conveying roller 342 and the third conveying roller 343 cannot contact the card paper, and the card paper cannot be conveyed in the conveying passage 345. If the width of the conveying passage 345 is too small, the card paper cannot pass through the conveying passage 345 smoothly. Since the first conveying roller 341, the second conveying roller 342 and the third conveying roller 343 are in a cylindrical shape, the inlet and outlet 113 of the conveying passage 345 are large and have an arc-shaped guide, which facilitates the feeding and discharging. The elastic pushing assemblies 35 are arranged at the two ends of the first conveying roller 341 and the two ends of the second conveying roller 342 to elastically press the conveying passage 345, thereby enhancing the friction between the card paper and the first conveying roller 341 and the second conveying roller 342, preventing the card paper from slipping in the conveying passage 345, and the card paper can also push the elastic pushing assemblies 35, so that the card paper can be conveyed smoothly in the conveying passage 345. After the card paper enters the conveying passage 345, it can push the elastic pushing assemblies 35, so that the card paper can be conveyed in the conveying passage 345 and the friction between the card paper and the first conveying roller 341 and the second conveying roller 342 is increased, thereby enabling the card paper to be conveyed smoothly in the conveying passage 345. The structure is simple and reasonable.

[0046] Referring to Figure 11 and Figure 12 In some alternative embodiments, the buffer delivery mechanism 40 comprises a fixed base 41, a second power assembly 44, a first conveying assembly 42 and a second conveying assembly 43 disposed on the fixed base 41. The first conveying assembly 42 is located above the second conveying assembly 43, and the second power assembly 44 is actuated to deliver the card paper between the first conveying assembly 42 and the second conveying assembly 43. Both the first conveying assembly 42 and the second conveying assembly 43 comprise a conveying belt 401, and the two conveying belts 401 contact each other to form a conveying section 402 for conveying the card paper. That is, the portion where the first conveying assembly 42 and the second conveying assembly 43 contact each other is the conveying section 402 for conveying the card paper. Specifically, a support plate 45 is disposed below the conveying section 402, and the support plate 45 is mounted on the fixed base 41. An elastic material pressing assembly 46 is disposed above the conveying section 402, and the elastic material pressing assembly 46 is used to increase the friction between the conveying section 402 and the card paper, so that the card paper can be conveyed in the conveying section 402.

[0047] Referring to Figure 11 and Figure 12 In some alternative embodiments, the buffer delivery mechanism 40 is provided with a guide plate 47 near one end of the conveying assembly 34, and the guide plate 47 is used to receive and guide the card paper, so that the card paper can be conveyed into the conveying section 402. A sensor 48 is further disposed above the guide plate 47, and the sensor 48 is used to determine the conveying position of the card paper. It can be understood that the card paper is conveyed into the conveying section 402 through the guide plate 47, and when the workpiece is not conveyed to the correct position, the card paper can be temporarily stored in the buffer delivery mechanism 40, and the workpiece can be a paper bag. After confirming that the paper bag is conveyed to the correct position, the second power assembly 44 is actuated to synchronize the first conveying assembly 42 and the second conveying assembly 43, so that the card paper in the conveying section 402 is conveyed and delivered into the paper bag to enter the next process. The support plate 45 located below the conveying section 402 is used to support the card paper in the conveying section 402, so as to prevent the card paper from being pressed and deformed. On the other hand, the elastic material pressing assembly 46 is disposed above the conveying section 402, and the pressing wheel 461 of the elastic material pressing assembly 46 is elastically pressed against the conveying section 402, which can increase the friction between the upper and lower conveying belts 401 and the card paper, so as to prevent the workpiece from slipping and being conveyed smoothly. The card paper can also push against the elastic material pressing assembly 46, so that the card paper can be conveyed smoothly in the conveying section 402.

[0048] Referring to Figure 13In some optional embodiments, the support frame 101 is connected with a lifting mechanism 50, by which the card stack delivery device 100 can be lifted and arranged on the support frame 101. The lifting mechanism 50 is arranged on both sides of the support frame 101, and includes a lifting guide rod 51 and a transmission member 52 connected to a power member such as a motor, so that the entire card stack delivery device 100 can be lifted along the lifting guide rod 51, thereby adjusting the height of the card stack delivery device 100 to a suitable position.

[0049] As shown in Figures 1 to 13 When the card stack delivery device 100 of the present application delivers cards, the card stack is automatically close to the discharge port 113 in the rack 11, the rolling assembly 13 of the discharge port 113 supports and limits the card stack, and can assist in distributing the cards. After the card stack is prepared, the first card is sucked by the taking assembly 22 for feeding, and the first card is distributed by the distributing assembly 12 when passing through the discharge port 113, so as to prevent double taking. Then, the taking assembly 22 is reset, the first card is adsorbed and conveyed to the conveying assembly 34 by the conveying belt 324 on the pushing assembly 32, at this time, the taking assembly 22 picks up the second card. The first card is conveyed to the buffer delivery mechanism 40 by the conveying assembly 34, the first card is sensed by the first sensor and paused in the buffer delivery mechanism 40 after conveying a certain distance, and the entire card stack delivery device 100 is paused. At this time, the second card is in the conveying assembly 34, and the taking assembly 22 picks up the third card. When the conveying device at the bottom of the card stack delivery device 100 conveys the workpiece close to the card stack delivery device 100, the second sensor on the conveying device senses the workpiece, the workpiece continues to convey a certain distance, and then the card stack delivery device 100 starts, the card in the buffer delivery mechanism 40 continues to convey and is delivered into the workpiece. Such a cycle is repeated.

[0050] As shown in Figures 1 to 13As shown, the card stack feeding device 100 of the present application is suitable for feeding another workpiece in a workpiece. Exemplarily, it can be used for feeding card paper in paper bags, paper boxes and the like workpieces. The card stack feeding device 100 comprises a support frame 101 and a stacking mechanism 10, a taking mechanism 20, a feeding mechanism 30 and a buffer feeding mechanism 40 arranged on the support frame 101. The stacking mechanism 10 comprises a rack 11 for placing card paper, which is arranged on the support frame 101 at a preset angle. The rack 11 is arranged at an angle so that the card paper in the rack 11 can automatically slide to the taking mechanism 20 after being taken to facilitate discharging. A rolling assembly 13 and a distributing assembly 12 are arranged around the discharge port 113 of the rack 11.
