Description

Technical Field

[0001] This utility model relates to the field of automated packaging technology, and in particular to a paper card feeding device. Background Technology

[0002] In daily life, thin sheet-like skincare products and household items, such as acne patches or stickers, require packaging in one-piece cardboard boxes. When using one-piece cardboard boxes, the first step is to load the box with material. After loading, the product is placed inside the box, and then the box is folded, glued, and the lid is applied to complete the packaging.

[0003] After packaging, a one-piece cardboard box is mostly square in shape, consisting of two opposite short sides, one long side, and a cardboard cover edge corresponding to the long side. The size of the cardboard cover edge is based on matching the bottom size of the cardboard box, so that when the cardboard cover edge is closed, it can cover the two short sides and one long side.

[0004] During the paper card box feeding process, the flattened paper card box needs to be transferred to a fixed station on the conveyor line. The fixed station on the conveyor line is usually limited by a pair of blocks, which restrict the paper card box between the blocks. When the flattened paper card box falls between the blocks, it is necessary to ensure that the short sides on both sides are folded vertically to ensure the smooth progress of the subsequent packaging process.

[0005] The key technical problem that urgently needs to be solved is how to automate the processes of flattening and loading paper card boxes, transferring them, and folding short edges, while also reducing the floor space occupied by the paper cards. Utility Model Content

[0006] Purpose of the utility model: In view of the problems existing in the prior art, this utility model provides a paper card feeding device. By placing stacked paper cards into a paper card material box, the material is picked up by the picking component and pushed to one side by the pushing component. The paper card pressing component is used to transfer the paper cards from the workbench to the conveyor line, thereby realizing automated feeding operation and reducing the footprint of paper cards.

[0007] Technical Solution: This utility model provides a paper card feeding device, including a conveyor line with pairs of stops spaced apart on the conveyor line, and a workbench located directly above the conveyor line. A paper card material box with a hollow bottom is located above the workbench, and a picking component is located directly below the paper card material box. A pushing component is located on one side of the picking component. A paper card pressing component is also fixed above the workbench located on one side of the paper card material box. A first notch is provided on the workbench opposite the paper card pressing component, and it is directly opposite the conveyor line below. After the picking component picks up a paper card, it pushes it to the workbench opposite the paper card pressing component via the pushing component. The paper card pressing component presses down until the paper card is transferred between the pairs of stops on the conveyor line.

[0008] Furthermore, the paper card material box is a structure that is set on the first support and has a hollow bottom, and the first support is fixed on the worktable; at least one pair of limiting stops are also provided at the bottom of the paper card material box.

[0009] Furthermore, the paper card material box includes four material box rods, which are located at the four corners of the paper card respectively, and the ends of the material box rods are provided with limit rollers.

[0010] Furthermore, a second notch is provided on the worktable located directly below the paper card material box, and the material picking component is located below the second notch.

[0011] Furthermore, the material handling component includes a suction cup assembly, which is positioned directly below the paper card material box and mounted on the material handling cylinder. The material handling cylinder is fixed to a second bracket, which is fixed to the lower surface of the workbench.

[0012] Furthermore, the feeding assembly includes a pair of strip slots disposed on the worktable and arranged along the transmission direction of the transmission line. The distance between the pair of strip slots is smaller than the width of the paper card, and a paper card pusher block is slidably disposed therein. A paper card sliding drive component is connected to the paper card pusher block.

[0013] Furthermore, the paper card sliding drive includes a first active conveyor belt pulley and a second driven conveyor belt pulley disposed below the worktable. The first active conveyor belt pulley and the second driven conveyor belt pulley are driven by a transmission shaft. A clamping block is disposed on the conveyor belt of the first active conveyor belt pulley. The clamping block is disposed at the actuation end of the first cylinder. A pair of paper card push blocks are respectively disposed on the conveyor belts of the first active conveyor belt pulley and the second driven conveyor belt pulley.

[0014] Furthermore, the size of the first notch groove matches the size of the bottom surface of the paper card, and limit bars are also provided on the three sides of the first notch groove.

[0015] Furthermore, the paper card pressing assembly includes a first pressing block, on which a second cylinder that can extend and retract vertically is provided.

[0016] Furthermore, a paper card guide plate is provided between the first notch and the transmission line, and the height of the lowest end of the paper card guide plate is greater than the width of the three folded edges of the paper card.

[0017] Beneficial effects: 1. This utility model involves stacking paper cards into a paper card material box, using a picking component at the bottom to sequentially remove the bottom paper card, and then using a pushing component to push the paper card to one side of the worktable. The paper card pressing component then presses the paper card onto the conveyor line, where it moves forward with the conveyor. This achieves the paper card picking and feeding operation.

[0018] 2. This utility model uses a limiting stop at the bottom of the paper card material box to prevent all the paper cards in the box from falling onto the worktable. When the material is retrieved by the material-picking component, a suction cup assembly picks up the paper card individually, using the suction cup to pick up the bottommost paper card. The material-picking cylinder extends and retracts vertically, moving the paper card down onto the worktable. During the retrieval process, the retraction force of the material-picking cylinder is greater than the blocking force of the limiting stop, thus removing the paper card from the paper card material box. To achieve the vertical retraction of the material-picking cylinder, a second notch is cut into the worktable.

[0019] 3. When the paper card of this invention is located on the workbench opposite the second notch, it needs to be moved to the first notch on one side of the workbench. During the movement, the paper card pusher moves left and right to drive the paper card to move on the surface of the workbench. The left and right movement of the paper card pusher is achieved by the paper card sliding drive component.

[0020] 4. Compared with the traditional method of using a drive motor, the paper card sliding drive of this utility model uses a first cylinder to drive the device. The first cylinder drives the clamping block to move left and right, and the clamping block drives the belt of the first active conveyor pulley to move left and right, thereby realizing the rotation of the first active conveyor pulley. The first active conveyor pulley drives the second driven conveyor pulley to rotate through the transmission shaft. This can realize the simultaneous left and right movement of the two paper card push blocks, thereby pushing the paper card to the first notch position on one side.

[0021] 5. The size of the first notch in this design matches the size of the bottom surface of the paper card. During the pressing process of the paper card pressing component, only the bottom surface of the paper card is pressed down, without affecting the four sides of the paper card. It can also prevent the paper card from shifting during the pressing process. The limiting strip plays a limiting role, ensuring that the paper card will not fall out of the pressing range of the paper card pressing component when the paper card pusher pushes to one side.

[0022] 6. The paper card guide plate of this utility model plays a guiding role. During the pressing process of the paper card pressing component, the paper card will be vertically downward along the guiding direction of the paper card guide plate until it falls between the two stops of the transmission line.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model discloses a paper card feeding device, see [link to relevant documentation] Figures 1-6 The system includes a transmission line 1 with pairs of stop blocks 27 spaced apart on the transmission line 1, and a workbench 2 located directly above the transmission line 1. A paper card material box with a hollow bottom is located above the workbench 2, and a material picking component is located directly below the paper card material box. A material pushing component is located on one side of the material picking component. A paper card pressing component is also fixed above the workbench 2 located on one side of the paper card material box. A first notch 5 is located on the workbench 1 directly opposite the paper card pressing component and is directly opposite the transmission line 1 below it. After the material picking component picks up the paper card 26, it pushes it to the workbench 2 directly opposite the paper card pressing component through the material pushing component. The paper card pressing component presses down until the paper card 26 is transferred between the pairs of stop blocks 27 on the transmission line 1.

[0030] In this embodiment, the paper card material box is a hollow structure mounted on the first support 21. For example, the paper card material box is composed of four material box rods 3, which are located at the four corners of the paper cards 26. The ends of the material box rods 3 are provided with limiting rollers 19. The first support 21 is fixed to the worktable 2. At least one pair of limiting stops 4 are also provided at the bottom of the paper card material box. In this embodiment, the limiting stops 4 are fixed by a pair of vertically arranged limiting rods 25. The limiting stops 4 protrude slightly inward relative to the limiting rods 25 to facilitate relative positioning of the paper cards 26 inside the paper card material box.

[0031] A second notch 6 is provided on the workbench 2 located directly below the paper card material box, and the material picking component is located below the second notch 6. The material picking component includes a suction cup assembly 7, which faces directly below the paper card material box and is mounted on a material picking cylinder 18. The material picking cylinder 18 is fixed to a second bracket 22 located on the lower surface of the workbench 2. In this embodiment, the suction cup assembly 7 is a set of four suction cups. When material needs to be picked up, the suction cup assembly 7 extends upward through the material picking cylinder 18. When the suction cup assembly 7 releases the paper card 26 at the bottom of the paper card material box, the suction cup assembly 7 is activated. After the suction cups adsorb the paper card 26, the material picking cylinder 18 pulls the paper card 26 downward. The bottommost paper card 26 overcomes the action of the limiting stop 4 and the limiting roller 19, leaves the paper card material box, and falls onto the workbench 2.

[0032] The feeding assembly includes a pair of strip grooves 8 disposed on the worktable 2 and arranged along the conveying direction of the conveyor line 1. The distance between the pair of strip grooves 8 is smaller than the width of the paper card 26, and a paper card pusher 9 is slidably disposed within each strip groove. A paper card sliding drive is connected to the paper card pusher 9. In this embodiment, the pair of strip grooves 8 are disposed on both sides of the second notch 6, and the paper card pusher 9 is driven to slide left and right within the strip grooves 8 by the paper card sliding drive.

[0033] The paper card sliding drive includes a first driving conveyor pulley 12 and a second driven conveyor pulley 13 located below the worktable 2. The first driving conveyor pulley 12 and the second driven conveyor pulley 13 are connected by a drive shaft 14. A clamping block 16 is installed on the conveyor belt of the first driving conveyor pulley 12, and the clamping block 16 is located at the actuating end of the first cylinder 17. A pair of paper card pushers 9 are respectively installed on the conveyor belts of the first driving conveyor pulley 12 and the second driven conveyor pulley 13. The first driving conveyor pulley 12 and the second driven conveyor pulley 13 are conventional belt pulley structures, which will not be further described here.

[0034] The size of the first notch 5 matches the size of the bottom surface of the paper card 26, and a limit stop strip 23 is also provided on the outer side of the three sides of the first notch 5 away from the second notch 6.

[0035] The paper card pressing assembly includes a pressing block 10, on which a vertically retractable second cylinder 11 is provided.

[0036] A paper card guide plate 24 is also provided between the first notch 5 and the transmission line 1. The height of the lowest end of the paper card guide plate 24 is greater than the width of the three folded edges of the paper card 26.

[0037] In this embodiment, the transmission line 1 is a conventional belt transmission structure with pairs of stops 27 spaced apart on the belt. In order to facilitate the adjustment of the spacing between the pairs of stops 27, the transmission line 1 can be designed as two parallel pulley structures, with each stop 27 set on a belt. By adjusting the relative rotation of the two parallel pulleys, the spacing between the two stops 27 can be adjusted to adapt to different paper card 26 sizes.

[0038] Working principle: 1. The staff put the stacked paper cards 26 into the paper card material box.

[0039] 2. Activate the material handling cylinder 18, which uses the suction cup assembly 7 to pick up the paper card 26 from the paper card box and pull it to the worktable 2. At this time, the paper card pusher 9 is in... Figure 1 The rightmost of the 8th strip in the middle.

[0040] 3. Start the first cylinder 17, which drives the clamping block 16 to push the first active transmission pulley 12 relative to... Figure 1 Scrolling from left to right, during the scrolling process, the paper card pusher 9 is positioned relative to... Figure 1The card slides from right to left in the slot 8, and the second driven conveyor pulley 13 moves in the same direction via the drive shaft 14, thus completing the transfer of the card from the second notch 6 to the upper surface of the first notch 5 by the card pusher 9. At this time, due to the action of the limiting stop 23, the three crease edges (2601 and 2602) and the card cover edge 2603 of the card are located on the four sides of the first notch 5. The bottom surface of the card is exactly located in the first notch 5.

[0041] 4. Start the second cylinder 11 to drive the pressing block 10 downward to press the paper card 26. The paper card 26 passes through the first notch 5 and is transferred to the lower transmission line 1. At this time, the transmission line 1 is not transmitting. When the pressing is in place, the second cylinder 11 moves upward, the transmission line 1 starts to move, and another pair of stops 27 moves to the bottom of the first notch 5, waiting for the next round of feeding.
