Description

Technical Field

[0001] The present application relates to the technical field of packaging material conveying, and in particular to an environmentally friendly packaging bag forming, processing and conveying device. Background Art

[0002] In today's society, the improvement of environmental awareness has prompted the packaging industry to constantly seek innovation and improvement, especially in the production process of packaging bags. Environmentally friendly packaging bag molding processing is an important technology in the modern packaging industry, which focuses on the environmental protection of the production process and the sustainability of materials.

[0003] The conveying link after the packaging bag is formed becomes particularly important. This link ensures that the packaging bag can be safely and efficiently transferred from the processing area to the next production or packaging link. The design of the conveying device must take into account the size, shape and material properties of the packaging bag to achieve smooth and fast transportation while avoiding any damage or deformation to the packaging bag.

[0004] The combination of environmentally friendly packaging bag forming and conveying can not only improve production efficiency and reduce labor costs, but also ensure the integrity and cleanliness of the packaging bags during the production process, ensuring that the packaging bags will not be damaged or deformed during high-speed production.

[0005] For example, a packaging bag conveying device with publication number CN110406167B relates to the technical field of packaging material manufacturing equipment. The prior art includes a conveying mechanism, a stacking conveyor belt and a blower; the conveying direction of the stacking conveyor belt is inclined upward, the front end of the stacking conveyor belt is connected to the end of the conveying mechanism, and the end of the conveying mechanism is higher than the front end of the stacking conveyor belt, so that when two adjacent packaging bags are respectively conveyed from the conveying mechanism to the stacking conveyor belt, the two adjacent packaging bags are stacked up and conveyed upward on the stacking conveyor belt; the blower is located in front of and above the stacking conveyor belt, and the air outlet direction forms a preset angle with the conveying direction of the stacking conveyor belt, so as to press the packaging bags conveyed by the conveying mechanism onto the stacking conveyor belt.

[0006] However, the above-mentioned prior art still has some defects when conveying packaging materials:

[0007] 1. In the above-mentioned prior art, the blower is located above the stacking conveyor belt, and its air outlet direction forms a preset angle with the conveying direction of the stacking conveyor belt 3, blowing and pressing the packaging bags so that the packaging bags can be stably attached to the stacking conveyor belt for transportation. However, in actual use, the packaging bags are generally light in weight and in sheet form, and are prone to float up and deviate from the predetermined path during transportation. At this time, the wind force of the blower may aggravate the floating phenomenon, resulting in the inability of the packaging bags to be stably attached to the stacking conveyor belt.

[0008] 2. Due to the diversity of packaging bag materials and sizes, the wind force and direction of the blower may not be able to adapt to all types of packaging bags, causing the position of the packaging bags on the conveyor belt to become unstable.

[0009] Based on this, under the above-mentioned viewpoints, the existing technology still has room for improvement in the way of packaging material conveying bags. Summary of the invention

[0028] The sliding seat then drives the connecting frame to make the insertion rod drive the vertical rod to pass through the slot until the insertion rod completely passes through the slot, and the driving shaft is driven to rotate again, so that the driving shaft drives the eccentric disk. At this time, the compressed return spring will push the connecting block, and the connecting block will drive the connecting rod to make the sliding sleeve retract. The torsion spring on the insertion rod forces the vertical rod to stand up, so that the vertical rod can push the packaging bag for transportation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The following is combined with Figures 1 to 14 This application is described in further detail.

[0045] The embodiment of the present application discloses an environmentally friendly packaging bag forming, processing and conveying device, which screens the packaging bags, removes unqualified packaging bags, and then performs palletizing and bundling processing.

[0046] Embodiment 1:

[0047] Reference Figure 1 , Figure 2 and Figure 3 As shown, an environmentally friendly packaging bag forming, processing and conveying device includes a support frame 1, a conveyor belt 2 is arranged in the support frame 1, a U-shaped partition plate 4 located in the conveyor belt 2 is arranged in the support frame 1, and a negative pressure chamber 41 located in the support frame 1 is formed between the U-shaped partition plate 4 and the conveyor belt 2.

[0048] After the packaging bags are processed and formed, they will fall into the feed frame 3 located on the conveyor belt 2 and arranged on the two support frames 1. The packaging bags will be stacked in the feed frame 3. An outlet 31 is opened on the side of the feed frame 3 facing the forward direction of the conveyor belt 2, and a flap 32 is hinged in the outlet 31.

[0049] When conveying packaging bags, several exhaust fans 42 arranged on the support frame 1 and located in the negative pressure chamber 41 will be started, and the exhaust fans 42 will extract the air in the negative pressure chamber 41. At this time, the conveyor belt 2 is started, and several groups of evenly distributed suction holes 21 are opened on the conveyor belt 2. When the suction holes 21 pass through the negative pressure chamber 41, the air will pass through the suction holes 21 into the negative pressure chamber 41, and then be discharged through the exhaust fans 42. At this time, the suction holes 21 will generate suction when passing through the upper side of the negative pressure chamber 41.

[0050] When a group of suction holes 21 pass through the guide frame 61 , the packaging bag will be sucked, and the sucked packaging bag will be driven to resist the flap 32 to force the flap 32 to rotate, so that the sucked packaging bag passes through the outlet 31 and is transported to the filter 5 set on the conveyor belt 2 .

[0051] The packaging bags are quality checked to ensure that each packaging bag meets specific quality standards, including checking the integrity, size, printing quality, etc. of the packaging bags. When the packaging bags fail to pass the screening, they will be automatically removed by the filter 5 to prevent unqualified products from entering the subsequent production links. The packaging bags that have passed the inspection of the filter 5 will continue to move along the conveyor belt 2 and prepare to enter the palletizer 6 set on the support frame 1 for packaging or storage.

[0052] After the sucked package leaves the feed frame 3, the packaging bags in the feed frame 3 fall down one by one and contact the conveyor belt 2. The flap 32 will naturally rotate to block the outlet 31 to prevent the packaging bags from passing through the outlet 31 until the next set of suction holes 21 passes through the feed frame 3 to suck the next packaging bag through the outlet 31.

[0053] Continue to refer to Figure 1 , Figure 2 and Figure 3 As shown, specifically, the screener 5 includes a visual sensor 51 arranged in a support frame 1 and located on the conveyor belt 2, a telescopic baffle 52 is hinged on the support frame 1 toward the conveying direction of the conveyor belt 2, a connecting baffle 53 is hinged at one end of the telescopic baffle 52, an adjusting screw 54 is rotatably penetrated on the support frame 1 and threadedly connected to the connecting baffle 53, and a transport belt 56 is arranged on one side of the conveying direction of the conveyor belt 2 in the two support frames 1.

[0054] After a group of suction holes 21 adsorb the packaging bag and pass through the outlet 31, the packaging bag will pass through the visual sensor 51. The visual sensor 51 will detect the integrity, size, printing quality, etc. of the packaging bag. At this time, the packaging bag that passes the inspection of the visual sensor 51 will continue to be conveyed on the conveyor belt 2. The packaging bag will hit the telescopic baffle 52 and then be centered. Then, through the connecting baffle 53, it will contact the roller 55 located between the two connecting baffles 53 and rotatably arranged on the adjusting screw 54. The roller 55 presses the packaging bag to prevent the packaging bag from tilting. At the same time, the packaging bag will hit the roller 55, causing the roller 55 to rotate on the adjusting screw 54.

[0055] After passing the roller 55 , the packaging bag enters the conveyor belt 56 through the rotating plate 57 rotatably arranged between the conveyor belt 2 and the conveyor belt 56 and is transported to the palletizer 6 for palletizing.

[0056] When the packaging bag fails the inspection, the rotating plate 57 arranged between the conveyor belt 2 and the conveyor belt 56 is driven to rotate by the existing motor driving technology. The rotating rotating plate 57 will tilt up, causing the unqualified packaging bag to fall into the collection box 58 arranged in the support frame 1 and located on the lower side of the conveyor belt 56. The collection box 58 can be disassembled for cleaning and replacement.

[0057] Since different packaging bags have different sizes, by rotating the adjusting screw 54, the adjusting screw 54 forces the two connecting baffles 53 to move to opposite sides or opposite sides through threaded connection, and at the same time, the telescopic baffle 52 will telescope with the movement of the connecting baffle 53, thereby adapting to packaging bags of different sizes.

[0058] Reference Figure 4 , Figure 5 and Figure 6 As shown, specifically, the palletizer 6 includes a guide frame 61 arranged in the support frame 1 and located in the conveying direction of the conveyor belt 56, a support plate 63 located below the guide frame 61 is arranged on one side of the support frame 1, a bottom plate 64 located directly below the guide frame 61 is arranged on the support plate 63, and a plurality of sliding grooves 65 distributed around the sides are jointly provided on the support plate 63 and the bottom plate 64, and a sliding block 66 is arranged in the sliding groove 65.

[0059] After the packaging bag enters the conveyor belt 56 , the conveyor belt 56 will transport the packaging bag to the guide frame 61 , and the packaging bag will fall onto the bottom plate 64 along the guide slope 62 provided on one side of the guide frame 61 .

[0060] When the number of packaging bags on the bottom plate 64 accumulates to a certain amount, the driving gear 68 set at the lower end of the support plate 63 is driven to rotate through the existing motor driving technology. The rotating driving gear 68 will drive the driving rack 69 set on the sliding block 66 through engagement, so that the driving rack 69 drives the sliding block 66 to move closer to the center of the bottom plate 64. The sliding block 66 will drive the vertical rod 67 set at the upper end of the sliding block 66 to align the edges of the stacked packaging bags, and then the stacked packaging bags are sent to the next process through the conveying bracket 7 set on the support plate 63 and located on one side of the bottom plate 64.

[0061] Reference Figure 7 , Figure 8 and Fig. 9As shown, specifically, the conveying bracket 7 includes a slide rail 71 arranged on the support plate 63 and located on one side of the base plate 64, a slide seat 72 is slidably arranged on the slide rail 71, a connecting frame 721 is rotatably arranged on the slide seat 72, slots 73 are symmetrically opened on the base plate 64, an insertion rod 74 connected to the connecting frame 721 is movably arranged in the slot 73, and one end of the insertion rod 74 away from the connecting frame 721 is hinged with a vertical rod 741 through a torsion spring (not shown in the figure).

[0062] After the edges of the packaging bags are aligned, the slide seat 72 is driven to move on the slide rail 71, and the connecting frame 721 is driven to move together through the slide rail 71, and the connecting frame 721 drives the insertion rod 74 to withdraw from the slot 73. At this time, the vertical rod 741 will push the stacked packaging bags to push the packaging bags out of the bottom plate 64, so that the packaging bags are driven together on the two insertion rods 74 and move with the connecting frame 721.

[0063] At the same time, the slide 72 is provided with a positioning gear 75 located at the rotation center of the connecting frame 721. The connecting frame 721 is provided with an adjusting gear 751 that meshes with the positioning gear 75 through the rotation of a motor. The insert rod 74 and the vertical rod 741 support the stacked packaging bags. After the packaging bags are moved out of the bottom plate 64 by driving the slide 72 to move on the slide rail 71, the adjusting gear 751 is driven to rotate by the motor. The rotating adjusting gear 751 will mesh with the positioning gear 75 to rotate the connecting frame 721 on the slide 72 to adjust the position of the packaging bags to connect with different existing equipment for subsequent processing.

[0064] The support frame 721 is provided with a plurality of guide rods 77 connected to the push plate 761 and the guide rods 77a are connected to the support frame 721 and the support frame 721 is provided with a plurality of guide rods 77b which are connected to the push plate 761 and the guide rods 77b ...

[0065] Reference Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, during the process of transporting packaging bags by the connecting frame 721, the packaging bags will continue to be stacked on the bottom plate 64. At this time, a sliding sleeve 771 corresponding to the vertical rod 741 is slidably provided on the insertion rod 74, a connecting rod 772 connected to the sliding sleeve 771 is slidably provided on the insertion rod 74, and a connecting groove 79 is opened on the insertion rod 74.

[0066] By driving the driving shaft 78 that is rotatably installed on the connecting frame 721 to rotate, the rotating driving shaft 78 will drive the eccentric disk 781 installed thereon to rotate together. The rotating eccentric disk 781 will interfere with the connecting rod 772, so that the connecting rod 772 drives the sliding sleeve 771 to move toward the vertical rod 741, and the sliding sleeve 771 moves to the hinge between the insertion rod 74 and the vertical rod 741, so that the vertical rod 741 flips over and compresses the torsion spring to be laid flat.

[0067] At the same time, the connecting rod 772 will drive the connecting block 791 set thereon and located in the connecting groove 79, so that the connecting block 791 moves together with the sliding sleeve 771 in the connecting groove 79, and compresses the return spring 792 set between the side of the connecting block 791 close to the vertical rod 741 and the connecting groove 79.

[0068] Then, the connecting frame 721 is driven by the sliding seat 72 to make the insertion rod 74 drive the vertical rod 741 to pass through the slot 73 until the insertion rod 74 completely passes through the slot 73, and the driving shaft 78 is driven to rotate again, so that the driving shaft 78 drives the eccentric disk 781. At this time, the compressed return spring 792 will push the connecting block 791, and the connecting block 791 will drive the connecting rod 772 to push the sliding sleeve 771 back onto the insertion rod 74. At the same time, the torsion spring will force the vertical rod 741 to stand up, so that the vertical rod 741 can push the packaging bag during the next transportation.

[0069] Embodiment 2:

[0070] Reference Fig.13 and Fig.14 On the basis of the first embodiment, a strapping device 8 is provided on the supporting plate 63 .

[0071] The strapping device 8 includes an L-shaped bracket 81 symmetrically arranged on both sides of the support plate 63, and a detachable storage frame 82 is arranged on the L-shaped bracket 81. The four sides of the two storage frames 82 are provided with guide slopes 84 inclined toward the opposite sides. The opposite sides of the two storage frames 82 are hinged with pressure plates 85 through torsion springs (not shown in the figure), and a connecting rope 86 is arranged between the two pressure plates 85 on the same storage frame 82.

[0072] A plurality of elastic cable ties are sleeved on the outside of the material storage frame 82, and the elastic cable ties will shrink and move in the inclined direction along with the guide slope 84. Then, slots 83 are symmetrically opened on the opposite sides of two of the material storage frames 82. After the insertion rod 74 and the vertical rod 741 support the stacked packaging bags, the packaging bags are moved between the upper and lower pressure plates 85 by driving the slide seat 72 to move on the slide rail 71.

[0073] Then, the guide wheel 87 rotatably arranged in the storage frame 82 is driven to rotate, and the rotating guide wheel 87 will shorten the traction rope 88 wrapped around it, and the traction rope 88 will pull the connecting rope 86 through the connection with the middle of the connecting rope 86, so that the two pressure plates 85 are rotated and tilted and the torsion spring is compressed to press on the stacked packaging bags. At this time, the elastic cable tie in the slot 83 will follow the pressure plate 85 and be put on the stacked packaging bags, thereby bundling the stacked packaging bags.

[0074] After the packaging tape is tied, the guide wheel 87 is reversed to lengthen the traction rope 88 wrapped around it. At this time, the compressed torsion spring will force the pressure plate 85 to rotate to tighten the connecting rope 86 and not return to the initial state. At the same time, the next elastic cable tie will be inserted into the card slot 83 along the guide slope 84, and then the insertion rod 74 and the vertical rod 741 support the tied packaging bag and move it to the next workstation.

[0075] The implementation principle of the present invention is:

[0076] (1): When the packaging bag is being transported, the exhaust fan 42 will extract the air in the negative pressure chamber 41. At this time, the conveyor belt 2 is started, and a plurality of groups of evenly distributed suction holes 21 are opened on the conveyor belt 2. When the suction holes 21 pass through the negative pressure chamber 41, the air will pass through the suction holes 21 into the negative pressure chamber 41, and then be discharged through the exhaust fan 42, thereby causing the suction holes 21 to generate suction when passing through the upper side of the negative pressure chamber 41.

[0077] (2): When a group of suction holes 21 pass through the guide frame 61, the packaging bag will be adsorbed. The adsorbed packaging bag will be driven to resist the flap 32, forcing the flap 32 to rotate, so that the adsorbed packaging bag passes through the outlet 31. The packaging bag will pass through the visual sensor 51, and the visual sensor 51 will detect the integrity, size, printing quality, etc. of the packaging bag. At this time, the packaging bag that passes the inspection of the visual sensor 51 will continue to be transported on the conveyor belt 2.

[0078] (3): The roller 55 located between the two connecting baffles 53 is rotated by contacting the adjusting screw 54 through the connecting baffle 53, and the roller 55 presses the packaging bag to prevent the packaging bag from tilting up. Then the conveyor belt 56 transports the packaging bag to the guide frame 61, and the packaging bag falls on the bottom plate 64 along the guide slope 62 set on one side of the guide frame 61.

[0079] (4): When the number of packaging bags on the bottom plate 64 reaches a certain amount, the driving gear 68 set at the lower end of the support plate 63 is driven to rotate through the existing motor driving technology. The rotating driving gear 68 will drive the driving rack 69 set on the sliding block 66 through engagement, so that the driving rack 69 drives the sliding block 66 to move closer to the center of the bottom plate 64, and the sliding block 66 will drive the vertical rod 67 set at the upper end of the sliding block 66 to align the edges of the stacked packaging bags.

[0080] (5): After the edges of the packaging bags are aligned, the slide seat 72 is driven to move on the slide rail 71, and the slide rail 71 drives the connecting frame 721 to move together, and the connecting frame 721 drives the insertion rod 74 to withdraw from the slot 73. At this time, the vertical rod 741 will push the stacked packaging bags to push the packaging bags out of the bottom plate 64, so that the packaging bags are driven together on the two insertion rods 74 and move with the connecting frame 721.

[0081] (6): By driving the connecting gear 762 to rotate, the rotating connecting gear 762 will drive the push plate 761 to press against the stacked packaging bags through a threaded connection, ensuring that the packaging bags do not move during the movement process, and can also ensure that the push plate 761 is aligned with the edges of the packaging bags on both sides of the vertical rod 741. The multiple guide rods 77 connected to the push plate 761 and slidingly penetrated on the connecting frame 721 can ensure the smooth movement of the push plate 761.

[0082] (7): When the connecting frame 721 is transporting the packaging bags, the packaging bags will continue to be stacked on the bottom plate 64. At this time, a sliding sleeve 771 corresponding to the vertical rod 741 is slidably provided on the insertion rod 74, and a connecting rod 772 connected to the sliding sleeve 771 is slidably provided on the insertion rod 74. A connecting groove 79 is opened on the insertion rod 74.

[0083] By driving the driving shaft 78 that is rotatably installed on the connecting frame 721 to rotate, the rotating driving shaft 78 will drive the eccentric disk 781 installed thereon to rotate together. The rotating eccentric disk 781 will interfere with the connecting rod 772, so that the connecting rod 772 drives the sliding sleeve 771 to move toward the vertical rod 741, and the sliding sleeve 771 moves to the hinge between the insertion rod 74 and the vertical rod 741, so that the vertical rod 741 flips over and compresses the torsion spring to be laid flat.

[0084] (8): At the same time, the connecting rod 772 will drive the connecting block 791 set thereon and located in the connecting groove 79, so that the connecting block 791 moves together with the sliding sleeve 771 in the connecting groove 79, and compresses the return spring 792 set between the side of the connecting block 791 close to the vertical rod 741 and the connecting groove 79.

[0085] (9): The slide seat 72 drives the connecting frame 721 so that the insertion rod 74 drives the vertical rod 741 to pass through the slot 73 until the insertion rod 74 completely passes through the slot 73, and then drives the drive shaft 78 to rotate again, so that the drive shaft 78 drives the eccentric disk 781. At this time, the compressed return spring 792 will push the connecting block 791, and the connecting block 791 will drive the connecting rod 772 to push the sliding sleeve 771 back onto the insertion rod 74. At the same time, the torsion spring will force the vertical rod 741 to stand up, so that the vertical rod 741 can push the packaging bag during the next transportation.

[0086] (10): Then, the insertion rod 74 and the vertical rod 741 support the stacked packaging bags, and the packaging bags are moved between the upper and lower pressure plates 85 by driving the slide seat 72 to move on the slide rail 71. The traction rope 88 will pull the connecting rope 86 through the connection with the middle of the connecting rope 86, so that the two pressure plates 85 rotate and tilt and compress the torsion spring to press on the stacked packaging bags. At this time, the elastic tie in the slot 83 will follow the pressure plate 85 and be put on the stacked packaging bags, thereby bundling the stacked packaging bags.

[0087] (11): When the packaging bag fails the inspection, the rotating plate 57 arranged between the conveyor belt 2 and the conveyor belt 56 is driven to rotate by the existing motor driving technology. The rotating rotating plate 57 will tilt up, causing the unqualified packaging bag to fall into the collection box 58 arranged in the support frame 1 and located on the lower side of the conveyor belt 56. The collection box 58 can be disassembled for cleaning and replacement.

[0088] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
