Description

Technical Field

[0001] This utility model relates to the field of automated processing technology, specifically to a paper bag processing equipment. Background Technology

[0002] As a common packaging material, the ease of opening and the stability of the bottom of paper bags are important indicators of their quality. Currently, paper bags are made by processing paper through multiple processes to create a paper bag prototype with a folded bottom. Then, a bottom clip is placed inside the paper bag and glued and folded to improve the support strength of the bottom. Most paper bags are made using this method. In related technologies, existing paper bag processing equipment usually uses cylinders or lead screws to place the bottom clips. This results in relatively high noise during the paper bag processing process due to the reciprocating motion of the cylinders or lead screws, making it difficult to balance the overall processing efficiency and stability.

[0068] The paper bag processing equipment of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0069] Reference Figures 1 to 3 As shown, the paper bag processing equipment provided in this embodiment of the present invention includes: a machine body 10, a support base 20, a first suction and release assembly 301, a second suction and release assembly 302, a first flexible drive mechanism 40, and a bottom opening mechanism 50. The machine body 10 has a plurality of conveying rollers 11 for conveying paper bags; the support base 20 has vertically arranged flipping guide grooves 21 on two symmetrical sides; the first suction and release assembly 301 is provided with a first suction nozzle 35 for adsorbing bottom cards and is located on one side of the support base 20; the second suction and release assembly 3021 is provided with a first suction nozzle 35 for adsorbing bottom cards and is located on the other side of the support base 20. The first suction and release assembly 301 and the second suction and release assembly 302 are used to convey paper bags along the flipping guide grooves 21. The components move alternately downwards and are guided and flipped by each flipping guide groove 21 during movement to change the direction of the first suction nozzle 35; the first flexible drive mechanism 40 is connected to the two sets of adsorption components 52 respectively, and is used to drive each adsorption component 52 to move on the support base 20 respectively; the bottom opening mechanism 50 is provided on the body 10 and is located below the two sets of first suction and release components 301. The bottom opening mechanism 50 includes two sets of second flexible drive mechanisms 53 and two sets of adsorption components 52. The two sets of second flexible drive mechanisms 53 are connected to the two sets of adsorption components 52 respectively, and are used to drive the two sets of adsorption components 52 to flip to adsorb the bottom of the paper bag, and force the adsorption components 52 to adsorb the bottom of the paper bag to drive the bottom of the paper bag to flip and unfold.

[0070] Specifically, the aforementioned support base 20 includes two side plates 22 and a top plate 23. The two side plates 22 are fixed to the body 10. The top plate 23 is located on top of the two side plates 22, and the flip guide grooves 21 are respectively located on the two side plates 22. The flip guide grooves 21 can be directly opened on the side plates 22 to achieve the supporting and guiding function for the first suction and discharge assembly 301 and the second suction and discharge assembly 302.

[0071] Furthermore, the flipping guide groove 21 includes a turning groove 211 and a straight groove 212, with the straight groove 212 connecting both ends of the turning groove 211. Specifically, the straight groove 212 is vertically arranged, and the turning groove 211 includes two connected inclined grooves, with the other ends of the two inclined grooves respectively connected to the straight groove 212. Each inclined groove forms an angle greater than 90° and less than 180° with the straight groove 212. Preferably, the two inclined grooves also form an angle greater than 90° and less than 180°. The flipping guide grooves 21 on the two side plates 22 can be symmetrically arranged. The first suction and discharge assembly 301 and the second suction and discharge assembly 302 are independently guided by their respective flipping guide grooves 21, ensuring the independence and flexibility of the first suction and discharge assembly 301 and the second suction and discharge assembly 302 when driven to work, and ensuring the stability of their respective operation.

[0072] Reference Figures 3 to 6 As shown, both the first suction and discharge assembly 301 and the second suction and discharge assembly 302 include: a guide member 31, a rocker arm 32, a flipping shaft 33, and a connecting plate 34. The guide member 31 is movably disposed in the flipping guide groove 21. One end of the rocker arm 32 is pivotally connected to the guide member 31. The first end of the flipping shaft 33 is fixedly connected to the other end of the rocker arm 32. The first suction nozzle 35 is disposed at the second end of the flipping shaft 33 and is provided with a suction cup. The first end of the flipping shaft 33 rotatably passes through one end of the connecting plate 34, and the other end of the connecting plate 34 is connected to the first flexible drive mechanism 40.

[0073] In this embodiment, the connecting plate 34 and the flexible drive mechanism 40 are connected, so that when the flexible drive mechanism 40 drives the connecting plate 34 to move linearly upward, the flipping shaft 33 passing through the connecting plate 34 can move linearly upward along the radial direction of the connecting plate 34. Since the flipping shaft 33 and the rocker arm 32 are fixedly connected, the linear movement of the flipping shaft 33 can drive the rocker arm 32 to move upward, so that the guide member 31 can enter the turning groove 211 from the lower straight groove 212 along with the rocker arm 32. The guide member 31 is movable in the turning groove 211, so that the guide member 31 is moved by the turning groove 211. When guided to the position of the straight groove 212 off the lower end, the rocker arm 32 is fixedly connected to the flipping shaft 33, so the rocker arm 32 will deflect with the guidance of the guide member 31. At the same time, the rocker arm 32 drives the flipping shaft 33 to rotate around its own axial direction. When the guide member 31 is driven to move from the turning groove 211 to the straight groove 212 at the upper end, the rocker arm 32 will continue to deflect with the guidance of the guide member 31 to be parallel to the straight groove 212, and simultaneously drive the flipping shaft 33 to continue to rotate to the position where the first suction nozzle 35 faces upward, thereby completing the flipping action of the first suction nozzle 35 from bottom to top.

[0074] Furthermore, after the first suction nozzle 35 completes the operation of sucking up the bottom card 60, the connecting plate 34 drives the flipping shaft 33 to move downward in a straight line. At the same time, the flipping shaft 33 can drive the rocker arm 32 to move downward. At this time, the guide 31 is in the upper straight groove 212, so that the guide 31 can enter the turning groove 211 from the upper straight groove 212 with the rocker arm 32. When the guide 31 is guided by the turning groove 211 to a position that is deviated from the upper straight groove 212, the rocker arm 32 will continue to deflect with the guidance of the guide 31. At the same time, the rocker arm 32 continues to drive the flipping shaft 33 to rotate around its own axial direction. Similarly, when the guide 31 is continued to be driven to move from the turning groove 211 to the lower straight groove 212, the rocker arm 32 will continue to deflect with the guidance of the guide 31 to be parallel to the straight groove 212. Thus, the flipping shaft 33 can continue to rotate to the position where the first suction nozzle 35 is facing downward, thereby completing the flipping action of the first suction nozzle 35 from top to bottom.

[0075] Optionally, a material pick-up notch 231 can be provided on the top plate 23, and the conveying end of the conveyor belt can be connected to the material pick-up notch 231. The bottom card 60 can be conveyed to the material pick-up notch 231 by the conveyor belt, so that when the first suction nozzle 35 moves upward, it can be adsorbed and removed from the conveyor belt, thereby improving the overall level of automation.

[0076] As a preferred embodiment, the guide member 31 can be a structure such as a roller to reduce the friction of the guide member 31 in the flip guide groove 21. Optionally, ball bearings can also be provided on the side wall of the flip guide groove 21 to reduce the friction between the guide member 31 and the flip guide groove 21 and ensure better stability during the guiding operation.

[0077] Furthermore, the aforementioned flipping shaft 33 includes a rotating section 331 and a planar section 332. One end of the rotating section 331 rotatably passes through the connecting plate 34 and is fixedly connected to the rocker arm 32. The planar section 332 is connected to the other end of the rotating section 331, and the first suction nozzle 35 is disposed on the planar section 332.

[0078] In a specific embodiment of this application, the first suction and discharge assembly 301 and the second suction and discharge assembly 302 are symmetrically arranged. The two flip shafts 33 can be symmetrically arranged by flipping 180 degrees around the radial direction. The plane positions of the two planar segments 332 are opposite and close to each other. For example, the planes opposite the two planar segments 332 can be spaced 0.8-3cm apart to ensure that the two flip shafts 33 will not cause stroke interference when they move up and down alternately, and to minimize the installation space of the two flip shafts 33. Optionally, the planar segment 332 can be a semi-cylinder or a planar cylinder.

[0079] Preferably, a hollow air pipe connector 38 can be provided on the aforementioned planar segment 332. The positions of the first suction nozzle 35 and the air pipe mounting seat are on opposite sides of the two planar segments 332. The air pipe connector 38 can be connected to a vacuuming device or the like via an air pipe. The first suction nozzle 35 can be provided on the air pipe connector 38 and interconnected, so that the vacuuming device can draw the air pipe connector 38 to a negative pressure state or blow in gas to switch to a positive pressure state. When the air pipe connector 38 is switched to a negative pressure state, the first suction nozzle 35 can perform an adsorption action on the base card 60. When the air pipe connector 38 is switched to a positive pressure state, the base card 60 can be placed.

[0080] Furthermore, each of the aforementioned side plates 22 is also provided with a slide rail 36 extending vertically. The slide rail 36 is connected to the connecting plate 34 via a slider 37, so that the connecting plate 34 can move along the length direction of the slide rail 36. When the connecting plate 34 is driven by the first flexible drive mechanism 40, the connecting plate 34 can move linearly along the length direction of the slide rail 36, so that the connecting plate 34 can maintain stable linear movement. During the movement, a thrust can be applied to the flipping shaft 33, so that the flipping shaft 33 can rotate with the deflection of the rocker arm 32, thereby completing the flipping action.

[0081] Reference Figure 3 As shown, the first flexible drive mechanism 40 includes: a first motor 41, a first rotating shaft 42, a second rotating shaft 43, a first transmission belt 44, and a second transmission belt 48. The first motor 41 is located at the bottom of the body 10. The first rotating shaft 42 is rotatably located at the bottom of the body 10 and is connected to the first motor 41 for transmission. The second rotating shaft 43 is rotatably located on the support base 20 and is arranged parallel to the first rotating shaft 42 in the axial direction. The two ends of the first transmission belt 44 are synchronously connected to one end of the first rotating shaft 42 and the second rotating shaft 43. The two ends of the second transmission belt 48 are synchronously connected to the other end of the first rotating shaft 42 and the second rotating shaft 43.

[0082] In this embodiment, the first motor 41 has a first gear 46 on its shaft, and a second gear 47 is provided at one end of the first rotating shaft 42. The first gear 46 and the second gear 47 mesh with each other. Optionally, the second gear 47 can also be disposed on the second rotating shaft 43, and the first motor 41 can be disposed near the second rotating shaft 43, achieving transmission through the meshing of the first gear 46 and the second gear 47. It can be understood that when the first motor 41 drives the first rotating shaft 42 to rotate, the first transmission belt 44 and the second transmission belt 48 can synchronously drive the second rotating shaft 43 to rotate, so that the first transmission belt 44 and the second transmission belt 48 can also rotate synchronously. Since there is a large transmission distance between the first rotating shaft 42 and the second rotating shaft 43, the two connecting plates 34 can... Driven by the first transmission belt 44 and the second transmission belt 48 respectively, the first rotating shaft 42 and the second rotating shaft 43 move linearly. This allows for smoother transmission and reduced noise during the rotation of the first suction nozzle 35, while also simplifying the structure and facilitating maintenance. Preferably, the connecting plate 34 connected to the first transmission belt 44 moves in the opposite direction to the connecting plate 34 connected to the second transmission belt 48. For example, the connecting plate 34 connected to the first transmission belt 44 can be located outside the first transmission belt 44, and the connecting plate 34 connected to the second transmission belt 48 can be located inside the second transmission belt 48. When the connecting plate 34 corresponding to the first transmission belt 44 moves upward, the connecting plate 34 corresponding to the second transmission belt 48 moves downward. It is understood that both ends of the first rotating shaft 42 and the second rotating shaft 43 are equipped with synchronous pulleys 45, and the first transmission belt 44 and the second transmission belt 48 synchronously pull the first rotating shaft 42 and the second rotating shaft 43 through the synchronous pulleys 45.

[0083] Reference Figure 7 As shown, the bottom-opening mechanism 50 includes two sets of adsorption substrate assemblies 51, which are mounted on the body 10 for adsorbing and fixing the paper bag. The two sets of adsorption substrate assemblies 51 are arranged opposite each other, and the distance between them can be adjusted to accommodate paper bags of different sizes. A second flexible mechanism 53 is located below the adsorption substrate assembly 52, which is mounted on the adsorption substrate assembly 51. Both assemblies 52 can be flipped between a first position and a second position. When the two sets of adsorption components 52 are flipped to the first position, they jointly adsorb and fix the bottom of the unattached paper bag. When the two sets of adsorption components 52 are flipped to the second position, they jointly stretch and unfold the bottom of the unattached paper bag to facilitate insertion into the bottom card 60. Two sets of second flexible drive mechanisms 53 are respectively located at the bottom of the two sets of adsorption substrate assemblies 51 and are respectively connected to the two sets of adsorption components 52 via transmission.

[0084] Reference Figures 8 to 10As shown, the adsorption substrate assembly 51 includes a base plate 511 and an adsorption plate 512. The base plate 511 is movably disposed on the body 10. The adsorption plate 512 is disposed on the base plate 511 and is used to adsorb and fix the paper bag under negative pressure. Further, the adsorption plate 512 is provided with a first through hole 5121 and a second through hole 5122. The first through hole 5121 is located on the top of the adsorption plate 512, and the second through hole 5122 is located on the side of the adsorption plate 512. The adsorption plate 512 is provided with a connecting cavity 5123 inside, which connects the first through hole 5121 and the second through hole 5122.

[0085] In this embodiment, the second through hole 5122 can be connected to each other by an air pipe connector, so that the air pipe connector can be connected to the vacuuming device through an air pipe, thereby connecting the second through hole 5122, the air pipe connector and the connecting cavity 5123 in sequence. The vacuuming device draws the connecting cavity 5123 to a negative pressure state, so that when the paper bag is transported to the adsorption plate 512, the paper bag can be adsorbed and fixed by the first through hole 5121 and the second through hole 5122. Thus, the two sets of adsorption components 52 complete the synchronous opening action of the bottom of the paper bag, ensuring that the adsorption of the paper bag is more stable during the opening process.

[0086] In a preferred embodiment, during the process of adjusting the distance between the two adsorption substrate assemblies 51, the body 10 is provided with a slide rail 36, and the base plate 511 is slidably connected to the slide rail 36 by a slider 37; furthermore, the bottom of the base plate 511 is also provided with a lead screw, and the lead screw is threadedly connected to the base plate 511.

[0087] In this embodiment, the lead screw can be driven to rotate by a motor or other means, so that the lead screw can drive the two base plates 511 to move along the length direction of the slide rail 36, thereby adjusting the distance between the two base plates 511, so that the distance between the two adsorption plates 512 can be adjusted to a suitable position, so that the two adsorption plates 512 can be used to adsorb and fix paper bags of different sizes. At the same time, the position of the second suction nozzle 525 can also be adjusted with the position of the base plates 511.

[0088] Specifically, a support block 513 is also provided on the base plate 511. The support block 513 is arranged adjacent to the adsorption plate 512, and the adsorption assembly 52 is pivotally mounted on the support block 513. Further, each adsorption assembly 52 includes: a rotating shaft 521, a first connecting rod 522, a second connecting rod 523, a flipping plate 524, and a second suction nozzle 525. The rotating shaft 521 is rotatably mounted on the support block 513. One end of the first connecting rod 522 is fixedly connected to the circumferential surface of the rotating shaft 521 to achieve synchronous movement with the rotating shaft 521. The other end of the second connecting rod 523 is fixedly connected to the first connecting rod 522 to achieve synchronous movement with the first connecting rod 522. The flipping plate 524 is mounted on the second connecting rod 523 to achieve synchronous movement with the second connecting rod 523. The second suction nozzle 525 is mounted on the flipping plate 524 and is used to move to a first position or a second position with the flipping plate 524.

[0089] In this embodiment, the first connecting rod 522 and the second connecting rod 523 can be vertically arranged, and the first connecting rod 522 and the second connecting rod 523 can be adjusted along their respective vertical directions. For example, the second connecting rod 523 can be adjusted along the vertical direction of the first connecting rod 522, or the first connecting rod 522 can be adjusted along the vertical direction of the second connecting rod 523. After adjustment, the second connecting rod 523 and the first connecting rod 522 can be fixed by screws or other means. The relative position of the second connecting rod 523 and the first connecting rod 522 is adjusted to adjust the distance between the flip plate 524 and the first connecting rod 522, ensuring that when the flip plate 524 and the second suction nozzle 525 are adjusted to the first position, they face the bottom of the paper bag. When the rotating shaft 521 rotates, the first connecting rod 522 can rotate synchronously with the rotating shaft 521, allowing the second connecting rod 522 to rotate. The connecting rod 523 drives the flipping plate 524 to flip to a first position or a second position. The first position can be the position where the second suction nozzle 525 is close to the adsorption plate 512, and the second position can be the position where the second suction nozzle 525 is away from the adsorption plate 512. When the second suction nozzle 525 is driven to flip to the first position, it can adsorb and fix the bottom of the paper bag. Then, the second suction nozzle 525 is flipped to the second position, so that the bottom of the paper bag can be stretched and unfolded with the second suction nozzle 525. Then, the bottom card 60 is placed, which makes the overall automation level higher and the stability of the bottom of the paper bag better when it is opened. Optionally, each flipping plate 524 can have multiple second suction nozzles 525, which can be spaced apart along the length of the flipping plate 524, so that multiple second suction nozzles 525 can adsorb multiple positions of the bottom of the paper bag at intervals, ensuring better stability during the adsorption process.

[0090] Furthermore, a first transmission wheel 526 is fixedly connected to one end of the rotating shaft 521, and the first transmission wheel 526 is connected to the second flexible drive mechanism 53. The second flexible drive mechanism 53 can drive the first transmission wheel 526 to rotate and simultaneously drive the rotating shaft 521 to rotate, so as to flip the second suction nozzle 525 to the first position or the second position.

[0091] Reference Figure 8 and Figure 9 As shown, each set of second flexible drive mechanisms 53 includes: a second motor 531, a second transmission wheel 532 and a third transmission belt 533. The second motor 531 is located below the base plate 511; the second transmission wheel 532 is connected to the second motor 531; one end of the third transmission belt 533 is connected to the second transmission wheel 532 and the other end is connected to the first transmission wheel 526.

[0092] In this embodiment, when the second motor 531 drives the second transmission wheel 532 to rotate, the second transmission wheel 532 can drive the first transmission wheel 526 to rotate through the third transmission belt 533. This causes the rotating shaft 521 to rotate with the first transmission wheel 526, causing the second suction nozzle 525 to rotate. The second suction nozzle 525 is driven by the third transmission belt 533. Compared with traditional methods such as cylinders and screws, this method can better reduce noise during operation.

[0093] The paper bag processing equipment provided by this utility model can transport the pre-formed paper bag to the bottom opening mechanism 50 through the conveying roller 11, so that the bottom opening mechanism 50 can adsorb the paper bag and open the bottom of the paper bag, thereby improving the support stability of the paper bag. Then, the first suction and release component 301 and the second suction and release component 302 are driven by the first flexible drive mechanism 40 to work alternately. Thus, when placing the bottom card 60, the first suction and release component 301 can adsorb the bottom card 60 and the second suction and release component 302 can place the bottom card 60, or the second suction and release component 302 can adsorb the bottom card 60 and the first suction and release component 301 can place the bottom card 60, thereby improving the overall bottom card 60 placement efficiency. At the same time, the first flexible drive mechanism 40 can better reduce the overall noise during the driving process.
