Description

Technical Field

[0001] This utility model relates to the field of carton production line technology, specifically to a novel feeding device before cartoning. Background Technology

[0002] With the continuous development of technology, packaging bag and box packaging has gradually become automated. In the current market, most packaging bags are sorted and arranged in an orderly manner by a bag sorting machine, so that they enter the feeding device in an orderly manner. Then, the packaging bags are conveyed to the boxing machine by the conveyor belt in the feeding device. Finally, the boxing machine pushes the packaging bags into the packaging box for packaging.

[0003] The existing feeding device smoothly delivers the material packaging bag onto the conveyor belt through a series of squeezing actions. However, during the conveyor belt transport process, the packaging bag will expand due to its own characteristics, which may cause the packaging bag to jam or even damage the packaging box during the boxing process, greatly reducing the stability of the boxing.

[0004] Furthermore, in the current market, most instruction cards, manuals, and other instruction cards are placed separately in the packaging box from the material packaging bag. While the packaging of material packaging bags has gradually become automated, the cards and instruction manuals are still manually placed into the packaging box. This results in high labor costs, is time-consuming and labor-intensive, and is prone to mispacking or omissions, thus greatly reducing the efficiency of packaging. Utility Model Content

[0005] To address the existing problems, this utility model proposes a novel feeding device before boxing, which improves the stability of boxing, realizes automated stacking and feeding of hand cards and material bags, improves boxing efficiency, reduces production costs, and avoids incorrect or missing boxing.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A novel feeding device for pre-packaging includes a feeding conveyor belt, a material bag pressing mechanism, a side pushing mechanism, a front pushing mechanism, a pressing limiting mechanism, and several hand-operated pushing mechanisms. Feeding hoppers are evenly spaced on the feeding conveyor belt, and the inner cavity of the feeding hopper matches the inner cavity of the packaging box. The feeding conveyor belt is connected to a material bag outlet and a pressing port on both sides of one of the feeding hoppers.

[0008] The side-pushing mechanism includes a side-pushing driver, a sliding tray and a side-pushing block connected to the side-pushing driver. The side-pushing block is fixed on one side of the sliding tray, and a side-fixing block is fixed above the other side of the sliding tray. The side-pushing block can be pushed by the side-pushing driver to form a pushing chamber that matches the inner cavity of the feeding hopper with the side-fixing block. The pushing chamber is located on one side of the material bag outlet and is aligned and connected to it. The material bag pressing mechanism is located above the sliding tray. The front-pushing mechanism is aligned and set on the side of the pushing chamber away from the material bag outlet.

[0009] The downward pressure limiting mechanism includes a limiting mechanism and a hand-operated downward pressure plate. The hand-operated downward pressure plate passes through the pressing port and is installed in the feeding hopper in a way that allows it to be inserted, removed, and moved up and down. The limiting mechanism drives and limits the feeding hopper to the opening.

[0010] The feeding conveyor belt has several hand-cranked discharge ports that are aligned and connected to the feeding hopper on the front side of the material bag discharge port, and the hand-cranked pushing mechanism is set to be aligned with the hand-cranked discharge ports.

[0011] Preferably, the sliding tray and the side push block are integrated into one unit.

[0012] Preferably, the side push block and the side fixing block are provided with grooves facing each other, the sliding tray is provided with multiple anti-pinch protrusions, the groove of the side fixing block is provided with multiple through holes that match the anti-pinch protrusions, and the anti-pinch protrusions and through holes are slidably engaged; the front end of the anti-pinch protrusion matches the arc surface of the groove of the side fixing block.

[0013] Preferably, the grooves of the side push block and the side fixing block form a pushing cavity, and the output end of the front push mechanism is provided with a front push plate, which matches the cross-section of the pushing cavity and is aligned with the pushing cavity.

[0014] Preferably, the side-pushing mechanism further includes a fixed bracket, a pallet mounting plate, a slider, and a slide rail. The fixed bracket is fixed to one side of the feeding conveyor belt, the slide rail is fixed to the fixed bracket, and the sliding pallet is fixed to the pallet mounting plate. The pallet mounting plate slides on the fixed bracket through the slider and the slide rail.

[0015] Preferably, the bottom of the inner cavity of the feeding hopper is provided with an anti-sticking protrusion to prevent the hand from completely sticking to the bottom, and the bottom of the pushing cavity is set higher than the anti-sticking protrusion.

[0016] Preferably, the pressing and limiting mechanism further includes a pull-in mechanism, a hand-clip pressing mechanism, and a connecting plate, all located outside the pressing port. The output end of the pull-in mechanism is connected to the connecting plate, the hand-clip pressing mechanism is fixed on the connecting plate, and the output end of the hand-clip pressing mechanism is connected to the hand-clip pressing plate, so that the hand-clip pressing plate can be pulled in and out and move up and down in the feeding hopper. The limiting mechanism includes a limiting plate and a limiting driver connected by a drive. The limiting plate matches the opening of the feeding hopper and is movably limited at the opening of the feeding hopper.

[0017] Preferably, the feed hopper opening is provided with multiple anti-pinch protrusions on both sides, and the limiting plate is provided with multiple anti-pinch grooves that match the anti-pinch protrusions on both sides.

[0018] Preferably, the feeding hopper is provided with a baffle on the side away from the material bag outlet.

[0019] Preferably, a bag sensor is provided above the sliding tray.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] In this invention, a hand-clip pushing mechanism delivers the hand-clip to the feeding hopper on the feeding conveyor belt, enabling automated hand-clip feeding. A bag pressing mechanism limits the height of the bag entering the sliding tray. A side push driver synchronously drives the side push block and the sliding tray, connecting the side push block with the side fixing block to limit the bag within the feeding cavity formed by the two. The feeding hopper with the hand-clip is conveyed to the front of the feeding cavity and stops. A hand-clip pressing plate is inserted into the feeding hopper to press down the hand-clip, and a limiting mechanism limits it at the opening of the feeding hopper. Subsequently, a forward pushing mechanism pushes the bag in the feeding cavity above the hand-clip in the feeding hopper. The feeding conveyor belt then delivers the bag... The card and material bag are conveyed to the cartoning machine via the feeding hopper. The feeding process before cartoning involves an infinite number of stacking and conveying cycles, thereby achieving automated stacking and feeding of the card and material bag, improving cartoning efficiency, reducing production costs, and preventing mis-packing or omissions. In addition, the pushing chamber matches the inner cavity of the feeding hopper, and the inner cavity of the feeding hopper matches the inner cavity of the packaging box. The limiting mechanism confines the material bag within the feeding hopper, ensuring that the card and material bag remain within the size range of the packaging box's inner cavity throughout the feeding process. This effectively prevents the packaging bag from swelling and affecting subsequent cartoning, greatly improving the stability of cartoning. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] like Figures 1 to 8 The image shows a novel feeding device for pre-packaging provided by this utility model, including a feeding conveyor belt 1, a material bag pressing mechanism 2, a side pushing mechanism 3, a front pushing mechanism 4, a pressing and limiting mechanism 5, and several hand-operated pushing mechanisms 6; feeding hoppers 7 are evenly spaced and fixed on the feeding conveyor belt 1, and the inner cavity of the feeding hopper 7 matches the inner cavity of the packaging box, that is, the inner cavity of the feeding hopper 7 is similar in shape to the inner cavity of the packaging box, and the size of the inner cavity of the feeding hopper 7 is slightly smaller than the size of the inner cavity of the packaging box; in this embodiment, as Figure 8 As shown, the packaging box is a pillow-shaped packaging box, so the inner cavity of the feeding hopper 7 is also a matching pillow-shaped inner cavity. In other embodiments, the packaging box can be square, prismatic, round, etc., and the corresponding inner cavity of the feeding hopper 7 can be a matching rounded rectangular inner cavity, circular inner cavity, etc.

[0037] like Figures 3 to 5 As shown, the feeding conveyor belt 1 has side walls on both sides of multiple feeding hoppers 7. The side walls have a material bag outlet 11 and a pressing port 12 at one of the feeding hoppers 7. The material bag outlet 11 and the pressing port 12 are aligned and connected with this feeding hopper 7. Since the feeding hoppers 7 are evenly spaced on the feeding conveyor belt 1, the transmission rhythm of the feeding conveyor belt 1 can be adjusted to ensure that each feeding hopper 7 can be aligned and connected with the material bag outlet 11 and the pressing port 12.

[0038] like Figures 3 to 5 As shown, the side push mechanism 3 includes a side push driver 31 and a sliding tray 32 and a side push block 33 that are driven and connected to the side push driver 31. The side push block 33 is fixed on one side of the sliding tray 32, and a side fixing block 8 is fixed above the other side of the sliding tray 32. The side push block 33, the side fixing block 8 and the sliding tray 32 form a feeding space, and the transition conveyor belt at the end of the bag sorting machine 10 is connected to this feeding space.

[0039] The side push block 33 is fixed to one side of the sliding tray 32, such as... Figure 6 As shown, the side fixing block 8 is fixed to the fixing bracket 36 by a fixing plate to be fixed above the other side of the sliding tray 32, rather than being directly fixed to the sliding tray 32. Therefore, the side push driver 31 can simultaneously push the sliding tray 32 and the side push block 33 towards the side fixing block 8; Figure 6 and Figure 7 As shown, the side push block 33 and the side fixing block 8 are provided with grooves 341 facing each other. When the side push block 33 is pushed to connect with the side fixing block 8 by the side push driver 31, the groove 341 of the side push block 33 and the groove 341 of the side fixing block 8 are connected to form the pushing cavity 34. The pushing cavity 34 is located on one side of the material bag outlet 11 and is aligned and connected with it, that is, the pushing cavity 34 is aligned and connected with the feeding hopper 7. The pushing cavity 34 matches the inner cavity of the feeding hopper 7, that is, the shape of the pushing cavity 34 is similar to the shape of the inner cavity of the feeding hopper 7, and the size of the pushing cavity 34 is slightly smaller than the size of the inner cavity of the feeding hopper 7.

[0040] like Figure 3 and Figure 5 As shown, the bag pressing mechanism 2 is located above the sliding tray 32. The bag pressing mechanism 2 drives the bag pressing plate at its output end to squeeze and limit the bag entering the feeding space.

[0041] like Figures 3 to 6 As shown, the front pushing mechanism 4 is aligned and set on the side of the pushing chamber 34 away from the material bag outlet 11. Specifically, the output end of the front pushing mechanism 4 is provided with a front pushing plate 41. The front pushing plate 41 is located on the side of the pushing chamber 34 away from the material bag outlet 11. The front pushing plate 41 matches the cross section of the pushing chamber 34 and is aligned with the pushing chamber 34 so that the front pushing mechanism 4 can drive the front pushing plate 41 to move into the pushing chamber 34.

[0042] like Figure 3 and Figure 5 As shown, the pressing and limiting mechanism 5 includes a limiting mechanism 51, a hand-held pressing plate 52, and a pulling and inserting mechanism 53, a hand-held pressing mechanism 54, and a connecting plate 55, all located outside the pressing port 12. The output end of the pulling and inserting mechanism 53 is connected to the connecting plate 55. The hand-held pressing mechanism 54 is fixed on the connecting plate 55, and its output end is connected to the hand-held pressing plate 52. That is, the pulling and inserting mechanism 53 can drive the connecting plate 55 to pull the hand-held pressing plate 52 into the feeding hopper 7, and the hand-held pressing mechanism 54 can drive the hand-held pressing plate 52 to move up and down along the connecting plate 55, thus allowing the hand-held pressing plate 52 to pass through the pressing port 12. The feed inlet 12 can be inserted and removed and moved up and down in the feed hopper 7; the limiting mechanism 51 is located above the feed hopper 7. Specifically, the limiting mechanism 51 includes a limiting plate 511 and a limiting driver 512. The limiting driver 512 can drive the limiting plate 511 to move up and down. The limiting plate 511 matches the opening of the feed hopper 7 and is located directly above the opening of the feed hopper 7. The limiting driver 512 can push the limiting plate 511 to cooperate at the opening of the feed hopper 7, or it can drive the limiting plate 511 to return to its initial state away from the opening of the feed hopper 7. That is, the limiting mechanism 51 is driven to be limited at the opening of the feed hopper 7.

[0043] like Figure 1 and Figure 2As shown, the feeding conveyor belt 1 has several hand-cranked discharge ports 13 on the front side of the material bag discharge port 11, and the hand-cranked pushing mechanism 6 is aligned with the hand-cranked discharge port 13. One, two, or more hand-cranked pushing mechanisms 6 and hand-cranked discharge ports 13 can be set according to actual needs. The distance between each pair of adjacent hand-cranked discharge ports 13, and the distance between each hand-cranked discharge port 13 and the material bag discharge port 11, is the distance of N feeding hoppers 7. The feeding hoppers 7 are evenly spaced on the feeding conveyor belt 1, so the transmission rhythm of the feeding conveyor belt 1 can be adjusted to ensure that each feeding hopper 7 is aligned with the hand-cranked discharge port. The material inlet 13 is aligned and connected, and it is ensured that when one of the feeding hoppers 7 is aligned and connected with the hand card outlet 13, the other feeding hopper 7 is also aligned and connected with the material bag outlet 11; the hand card pushing mechanism 6 includes a hand card feeding bin 61, a push driver 62 and a door opening mechanism 63. The hand card feeding bin 61 is connected to the card issuing machine or instruction manual issuing machine 20. The hand card outlet 13 is opened by the door opening mechanism 63. The push driver 62 can push the cards or instruction manuals issued by the card issuing machine or instruction manual issuing machine 20 from the hand card feeding bin 61 through the hand card outlet 13 into the feeding hopper 7;

[0044] like Figures 3 to 5 As shown, a material bag sensor 9 is provided above the sliding tray 32;

[0045] During operation, the feeding conveyor belt 1 is started, and the card issuing machine or instruction manual issuing machine 20 issues hand cards into the hand card feeding hopper. When the feeding hopper 7 is detected to have reached the hand card discharge port 13, the feeding conveyor belt 1 stops conveying, and the hand card discharge port 13 is opened through the door opening mechanism, pushing the driver to push the hand card into the feeding hopper 7. Subsequently, the feeding conveyor belt 1 drives the feeding hopper 7 containing the hand cards forward. After the material package manager 10 oriented and sorts the materials, they are orderly arranged from the transition conveyor belt at its end into the feeding space formed by the side push block 33, the side fixing block 8, and the sliding tray 32. During this process... The material bag is detected by the material bag sensor 9, which sends a signal to the controller. Upon receiving the signal, the controller first controls the material bag pressing mechanism 2 to drive its output end material bag pressing plate to squeeze the material bag and maintain this state. Then, it controls the side push driver 31 to simultaneously push the sliding tray 32 and the side push block 33 to move the material bag towards the side fixing block 8. Finally, the groove 341 of the side push block 33 connects with the groove 341 of the side fixing block 8 to limit the material bag in the pushing cavity 34. At the same time, the feeding hopper 7 with a hand clamp is conveyed by the feeding conveyor belt 1 to the material bag outlet 1. At points 1 and 12, when alignment with both is detected, the controller stops the feeding conveyor belt 1. At this time, the controller controls the insertion mechanism 53 to push the hand-clip pressing plate 52 through the pressing port 12 and insert it into the feeding hopper 7. Simultaneously, the hand-clip pressing mechanism 54 controls the hand-clip pressing plate 52 to gently press down on the hand-clip located at the bottom of the feeding hopper 7. At the same time, the limit driver 512 pushes the limit plate 511 to limit its engagement at the opening of the feeding hopper 7. Then, the controller controls the forward pushing mechanism 4 to push the forward pushing plate 41 into the pushing chamber 34 to push the material bag into the feeding hopper 7. At this time, the material bag is located... Above the hand card pressing plate 52, after the operation is completed, the controller controls the material bag pressing mechanism 2, the side push driver 31, the insertion and withdrawal mechanism 53, the limit driver 512 and the forward push mechanism 4 to return to the initial state. After the insertion and withdrawal mechanism 53 returns to the initial state, the controller controls the hand card pressing mechanism 54 to return to the initial state. Then the controller starts the feeding conveyor belt 1 to move forward, thus completing one automated stacking and feeding operation of hand cards and material bags. The feeding process before boxing is an infinite stacking and conveying cycle operation. Simultaneously, the feeding conveyor belt 1 conveys the feeding hopper 7 with hand cards and material bags to the boxing machine for boxing.

[0046] By setting a hand-card pushing mechanism 6, the hand-card can be automatically fed into the feeding hopper 7, realizing automated hand-card feeding. Secondly, during the operation of the side push driver 31 pushing the sliding tray 32 and the side push block 33 towards the side fixed block 8, the bag pressing mechanism 2 always remains in a pressing state to avoid the bag from expanding beyond the feeding space formed by the side push block 33, the side fixed block 8, and the sliding tray 32 during the side push process, thus preventing the bag from getting stuck. Next, in the side push mechanism 3, the side push block 33 and the sliding tray 32 are fixedly connected, so that the side push driver 31 pushes the sliding tray 32 and the side push block 33 simultaneously. Compared with pushing the side push block 33 alone, this can prevent the bag from being stuck in the gap between the sliding tray 32 and the side push block 33 during the push process. Furthermore, the pushing cavity 34 formed by the groove 341 of the side push block 33 and the groove 341 of the side fixed block 8 matches the inner cavity of the feeding hopper 7, and the inner cavity of the feeding hopper 7 matches the inner cavity of the packaging box. The limiting plate 511 is fitted at the opening of the feeding hopper 7. By confining the material package within the feeding hopper 7, the cards and material packages remain within the dimensions of the packaging box cavity throughout the feeding process. This effectively prevents the packaging bag from swelling and affecting subsequent boxing, greatly improving the stability of boxing. Next, the front push plate 41 matches the cross-section of the pushing cavity 34 and is aligned with the pushing cavity 34. The pushing cavity 34 is aligned and connected to the feeding hopper 7, allowing the front push plate 41 to accurately push the material package into the feeding hopper 7. Furthermore, since the bottom of the feeding hopper 7 is arc-shaped, the hand card will float at the bottom of the feeding hopper 7 due to its own rigidity if there is no pressure. By setting the hand card pressing plate 52, the hand card can be pressed down at the bottom of the feeding hopper 7, preventing the hand card from being pushed and bent or damaged during the pushing of the material package by the front push mechanism 4. Finally, the cyclical operation of an unlimited number of hand cards and material packages for automated stacking and feeding enables automated stacking and feeding of hand cards and material packages, improving boxing efficiency, reducing production costs, and preventing mis-packing and omissions.

[0047] Furthermore, such as Figure 6 and Figure 7 As shown, the sliding tray 32 and the side push block 33 are integrated, which completely avoids the gap between the sliding tray 32 and the side push block 33, and more effectively prevents the bag from getting stuck during the pushing process.

[0048] Furthermore, such as Figures 3 to 7As shown, the sliding tray 32 is provided with multiple anti-pinch protrusions 35, and the groove 341 of the side fixing block 8 is provided with multiple through holes 81 that match the anti-pinch protrusions 35. The anti-pinch protrusions 35 and the through holes 81 slide in fit. When the side push driver 31 pushes the sliding tray 32 and the side push block 33 to move towards the side fixing block 8, the multiple anti-pinch protrusions 35 pass through the through holes 81 and slide along the through holes 81. By limiting the sliding of the anti-pinch protrusions 35 by the through holes 81, the sliding stability of the sliding tray 32 can be improved. In this process, due to the multiple anti-pinch protrusions 35, the edge of the material bag near the side fixing block 8 is not easy to enter the gap between the sliding tray 32 and the side fixing block 8, thus effectively avoiding the phenomenon of material bag jamming. In addition, as Figure 6 and Figure 7 As shown, the front end of the anti-pinch protrusion 35 matches the arc surface of the groove 341 of the side fixing block 8, and the front end of the anti-pinch protrusion 35 starts at the opening of the groove 341 of the side push block 33. Therefore, when the groove 341 of the side push block 33 and the groove 341 of the side fixing block 8 are connected to form the pushing cavity 34, the front end of the anti-pinch protrusion 35 ends in the through hole 81 of the groove 341 of the side fixing block 8. At this time, because the front end of the anti-pinch protrusion 35 matches the arc surface of the groove 341 of the side fixing block 8, the front end of the anti-pinch protrusion 35 forms a flat arc surface with the groove 341 of the side fixing block 8.

[0049] Furthermore, such as Figure 6 and Figure 7 As shown, the side pushing mechanism 3 also includes a fixed bracket 36, a pallet mounting plate 37, a slider 38, and a slide rail 39. The fixed bracket 36 is fixed to one side of the feeding conveyor belt 1, the slide rail 39 is fixed on the fixed bracket 36, and the sliding pallet 32 ​​is fixed on the pallet mounting plate 37. The pallet mounting plate 37 slides on the fixed bracket 36 through the slider 38 and the slide rail 39.

[0050] Furthermore, such as Figure 8 As shown, the bottom of the inner cavity of the feeding hopper 7 is provided with an anti-sticking protrusion 71. When the hand card pressing plate 52 presses the hand card down moderately on the bottom of the feeding hopper 7, the hand card will not completely stick to the bottom of the feeding hopper 7 due to the anti-sticking protrusion 71. In addition, the bottom of the pushing cavity 34 is set higher than the anti-sticking protrusion 71, so the hand card can be pressed down moderately between the anti-sticking protrusion 71 and the bottom of the pushing cavity 34. This can prevent the two sides of the hand card from curling up due to excessive pressing, and can also allow the front pushing mechanism 4 to smoothly push the material bag into the feeding hopper 7 above the hand card. When the material bag enters the feeding hopper 7 above the hand card, due to the weight of the material bag and the setting of the anti-sticking protrusion 71, only the hand card part can contact the bottom of the feeding hopper 7. Therefore, when the feeding hopper 7 enters the cartoning machine for cartoning, the hand card and the packaging bag are easily pushed into the packaging box by the pushing mechanism of the cartoning machine.

[0051] Furthermore, such as Figure 8As shown, the feed hopper 7 has multiple anti-pinch protrusions 72 on both sides of its opening, such as... Figure 5 As shown, the limiting plate 511 has multiple anti-pinch grooves on both sides that match the anti-pinch protrusions 72. Through the cooperation of the anti-pinch protrusions 72 and the anti-pinch grooves, the material bag can be prevented from being clamped into the gap between the limiting plate 511 and the opening of the feeding hopper 7 during the process of the front pushing mechanism 4 pushing the material bag into the feeding hopper 7.

[0052] Furthermore, such as Figures 2 to 5 As shown, the feeding hopper 7 is provided with a baffle 73 on the side away from the material bag outlet 11, which can prevent the hand card and material bag from exceeding the feeding hopper 7 when the hand card pushing mechanism 6 pushes the hand card into the feeding hopper 7 and when the forward pushing mechanism 4 pushes the material bag into the feeding hopper 7, thus affecting subsequent processes.

[0053] In summary, this utility model, through the feeding conveyor belt 1, the material bag pressing mechanism 2, the side pushing mechanism 3, the front pushing mechanism 4, the pressing limiting mechanism 5, and several hand-held push mechanisms 6, can complete an unlimited number of stacking and feeding cycles, thereby realizing automated stacking and feeding of hand-held cards and material bags, improving boxing efficiency, reducing production costs, and avoiding mis-packing and omissions; furthermore, the pushing cavity 34 matches the inner cavity of the feeding hopper 7, and the inner cavity of the feeding hopper 7 matches the inner cavity of the packaging box, and the limiting mechanism 51 restricts the material bag to the feeding position. In the hopper 7, the cards and material bags remain within the dimensions of the packaging box cavity throughout the feeding process, effectively preventing the packaging bags from swelling and affecting subsequent boxing, thus greatly improving the stability of boxing.
