Description

Technical Field

[0001] This utility model relates to the field of cardboard box packaging, and in particular to an automatic packaging machine that prevents air bubbles. Background Technology

[0002] Cardboard box packaging is a crucial part of logistics, warehousing, and goods transportation; during the packaging process, an automatic packaging machine that prevents air bubbles is used to seal the top of the cardboard box.

[0003] Traditional bubble-proof automatic packing machines often have air bubbles inside the carton after the tape adheres to it during the sealing process, resulting in poor adhesion and a poor bonding effect.

[0004] Existing packaging machines mostly focus on the flipping mechanism, with few solutions considering this aspect. The applicant's earlier Chinese patent application CN117719753A describes a fully automatic paper bag flipping packaging machine that uses an integrated design to drive the mechanism, enabling it to package paper bag products in multiple sizes.

[0005] Chinese patent document CN106628388A describes a fully automatic box-opening and packing machine that uses an electromagnet to disassemble the gripping mechanism after power is cut off, thereby facilitating replacement, maintenance and cleaning.

[0006] Chinese patent document CN112278373A describes a fully automatic tape winding and packaging machine, which partially solves the problem of adhesive sealing by setting up an adhesive tape pasting device.

[0031] The present invention will be further described below by way of embodiments, but the description is exemplary and the present invention is not limited to the scope of the embodiments described.

[0032] like Figure 1-9 As shown, the automatic bubble-proof packaging machine includes a packaging conveyor 2; its characteristic is that it further includes:

[0033] Cover 6, which is located above the packing conveyor 2, has linear modules 4 connected to both sides of the cover 6, and the bottom of the linear modules 4 is fixedly connected to the frame of the packing conveyor 2.

[0034] Flat plate 7, which is fixedly installed on the right side of the cover 6, and the right side of the flat plate 7 is provided with a folding mechanism 8;

[0035] Sealing mechanism 9 is installed inside the right side of cover 6; sealing mechanism 9 is provided with a pressing component, and a side pressing component is provided on the side of sealing mechanism 9 away from plate 7;

[0036] The compaction mechanism 10 is installed inside the cover 6 and is located on the left side of the sealing mechanism 9;

[0037] The brushing mechanism 12 is located on the right side of the sealing mechanism 9, and the brushing mechanism 12 is connected to a shaking part.

[0038] like Figure 1 As shown, as a preferred technical solution, the left and right sides of the packaging conveyor 2 are respectively provided with a discharge conveyor 3 and a feed conveyor 1; the carton to be packaged is placed on the feed conveyor 1 and input to the right side of the packaging conveyor 2 through the feed conveyor 1, and then the carton is conveyed by the packaging conveyor 2. After being packaged and sealed on the packaging conveyor 2, it is conveyed to the discharge conveyor 3 and discharged through the discharge conveyor 3.

[0039] like Figure 1-2As shown, as a preferred technical solution, it also includes a centering mechanism 5; after the carton is conveyed to the right side of the packing conveyor 2, it enters the centering mechanism 5, where the carton is centered before being conveyed; the centering mechanism 5 includes two first screws 501; the front and rear threads of the first screws 501 have opposite directions of rotation, and both the front and rear threads of the first screws 501 are threadedly connected to a nut seat 502. The nut seat 502 located on the front side of the first screw 501 and the nut seat 502 located on the rear side of the first screw 501 are both fixedly mounted with a movable seat 503. The first screws 501 are rotatably connected to the frame of the packing conveyor 2, and a pulley 504 is fixedly mounted at the ends of both first screws 501. A transmission belt 505 is wound between the two pulleys 504. One end of one of the first screws 501 is connected to a first motor 506, and the first motor 506 is fixedly mounted on the frame of the packing conveyor 2. The packing conveyor 2 is a roller conveyor, such as... Figure 1 As shown, the movable seat 503 is located above the roller conveyor, while the first screw 501 and the nut seat 502 are both located below the rollers of the roller conveyor. Figure 2 As shown, the nut seat 502 is fixed to the bottom of the movable seat 503 by the vertical rod 905. The vertical rod 905 passes through the groove between the rollers. When the movable seat 503 in the centering mechanism 5 is adjusted and moved, the vertical rod 905 moves in the groove. The centering mechanism 5 and the packaging conveyor 2 do not affect each other.

[0040] After the carton is conveyed into the right side of the packing conveyor 2, it is positioned between two movable seats 503. The first motor 506 drives a single first screw 501 to rotate forward, and the two pulleys 504 and the transmission belt 505 drive the two first screws 501 to rotate synchronously. Through the threaded connection between the first screw 501 and the nut seat 502, with the front and rear threads of the first screw 501 rotating in opposite directions, the front and rear nut seats 502 drive the two movable seats 503 closer together, pushing the carton to center it. After the carton is centered, it is sealed and packed, and then conveyed away from the discharge conveyor 3. Next, the first motor 506 drives the single first screw 501 to rotate in the opposite direction, driving the two movable seats 503 to move away from each other, creating a sufficient distance to allow the next carton to enter.

[0041] The distance between the two movable seats 503 is adjustable to center cartons of different widths. The straight module 4 adjusts the height of the cover 6, the flat plate 7, the folding mechanism 8, and the internal structure of the cover 6 to meet the packaging needs of cartons of different heights. Through the above design, the packaging needs of cartons of different sizes can be met.

[0042] like Figure 2-3As shown, as a preferred technical solution, the folding mechanism 8 includes a second motor 801 fixedly mounted on the plate 7; the second motor 801 is a dual-axis motor, and a second screw 802 is fixedly mounted on each of the two output shaft ends of the second motor 801. The threads of the two second screws 802 are opposite in direction, and each of the two second screws 802 is provided with a movable frame 809. The movable frame 809 has a threaded hole that is threadedly connected to the second screw 802. The movable frame 809 has a guide hole, and a guide post 803 is connected to the guide hole with clearance fit. Side frames 808 are fixedly mounted on both ends of the guide post 803, and the side frames 808 are fixedly connected to the side wall of the plate 7. The end of the second screw 802 away from the second motor 801 is rotatably connected to the side frame 808. Push bars 804 are fixedly mounted on both movable frames 809.

[0043] like Figure 2 As shown, as a preferred technical solution, the folding mechanism 8 further includes a frame 805 fixed to the top of the plate 7; two first electric push rods 806 are fixedly installed on the frame 805, and pressure heads 807 are fixedly installed on the output shaft ends of the two first electric push rods 806.

[0044] After the cardboard box is centered, it enters the area below the folding mechanism 8, as follows: Figure 5 As shown, the top of the carton has four side flaps that need to be folded, with the left and right side flaps as follows: Figure 5 As shown, the box is in an inclined state. The first electric push rod 806 extends, causing the pressure head 807 to press down on the left and right side covers, folding them. Then, the second motor 801 drives the two second screws 802 to rotate together. Through the threaded transmission between the second screws 802 and the screw holes, and the guidance of the guide holes and guide posts 803, the two movable frames 809 drive the two push bars 804 to move closer to each other. The push bars 804 push the front and rear side covers of the carton to fold and cover the left and right side covers. After the front and rear side covers are folded, there is a gap between the two side covers, so that the front and rear side covers will not touch the pressure head 807 or the first electric push rod 806 during the folding process and after folding.

[0045] After the top side cover of the carton is folded, the carton is conveyed by the packing conveyor 2 into the space under the flat plate 7. The flat plate 7 limits the top of the carton, keeping the top side cover of the carton folded as it enters the space under the cover 6.

[0046] After the top of the carton is folded, the second motor 801 drives the second screw 802 to rotate, causing the two push bars 804 to reset and open, and the first electric push rod 806 to retract, causing the pressure head 807 to move to the high position.

[0047] like Figure 6-9As shown, as a preferred technical solution, the sealing mechanism 9 includes a pressure block 902; a side plate 901 is fixedly installed at both the front and rear ends of the pressure block 902, a roller 909 is rotatably installed between the two side plates 901, and an adhesive tape 910 is wound on the roller 909; a guide roller 917 is provided below the roller 909, and the guide roller 917 is rotatably installed between the two side plates 901; the adhesive tape 910 passes around the guide roller 917, and the adhesive tape 910 extends to cover the bottom of the pressure block 902; a fusible heating element 918 is provided on the bottom left side of the pressure block 902.

[0048] like Figure 7 and Figure 9 As shown, as a preferred technical solution, it further includes an adsorption mechanism 11; the adsorption mechanism 11 includes an adsorption cavity 1103 formed at the bottom of the pressure block 902, a perforated plate 1104 provided at the bottom opening of the adsorption cavity 1103, a connector 1101 connected to the adsorption cavity 1103, and a spiral hose 1102 connected to the connector 1101, the top end of the spiral hose 1102 being fixedly connected to the top of the cover 6. The top end of the spiral hose 1102 is connected to a negative pressure suction device; by drawing negative pressure through the negative pressure suction device, a negative pressure is formed in the adsorption cavity 1103 through the spiral hose 1102 and the connector 1101, thereby adsorbing the tape 910 at the bottom of the pressure block 902.

[0049] like Figure 9 As shown, as a preferred technical solution, the pressing assembly includes a second electric push rod 915 fixedly installed on the side wall of the cover 6; the second electric push rod 915 is fixedly installed with a pressing seat 916, the left side of the pressing seat 916 is provided with a pressing inclined surface, the side plate 901 is fixedly installed with a pressure receiving seat 911, the top of the pressure receiving seat 911 is provided with a first pressure receiving inclined surface; the side plate 901 is fixedly installed with a connecting frame 904, the connecting frame 904 is fixedly installed with a fixing strip 912, the fixing strip 912 is elastically connected to the top inner wall of the cover 6 through a second spring 914, the fixing strip 912 is fixedly installed with a guide rod 913, the guide rod 913 is connected to the guide groove opened on the cover 6 with clearance.

[0050] like Figure 8-9 As shown, as a preferred technical solution, the side pressure assembly includes a push block 903 and a guide sleeve 906; the front and rear sides of the guide sleeve 906 are fixedly connected to the connecting frame 904, a vertical rod 905 is slidably installed on the guide sleeve 906, the push block 903 is fixedly installed at the bottom end of the vertical rod 905, and the push block 903 is located to the left of the pressure block 902; a fixing seat 907 is fixedly installed inside the bottom of the guide sleeve 906, and the fixing seat 907 is elastically connected to the top end of the vertical rod 905 through a first spring 908; a second pressure inclined surface is provided on one side of the vertical rod 905.

[0051] The cardboard box is conveyed by the packing conveyor 2, moving from the flat plate 7 towards the sealing mechanism 9. After the left side of the cardboard box moves to the bottom of the pressure block 902, the sealing mechanism 9 then... Figure 9 As shown, the second electric push rod 915 extends, pushing the squeezing seat 916 to the left. The squeezing seat 916 squeezes and pushes the first pressure-receiving slope of the pressure seat 911 through the squeezing slope, causing the sealing mechanism 9 to move downwards as a whole until the horizontal surface of the bottom of the squeezing seat 916 contacts and abuts the top of the pressure seat 911. At the same time, the second spring 914 is stretched, and the movement of the sealing mechanism 9 is guided by the guide rod 913 and the guide groove. The above process causes the tape 910 at the bottom of the pressure block 902 to press against the position to be sealed on the top left side of the carton (after the carton is centered, the position to be sealed is aligned with the sealing mechanism 9, and the sealing position is...). At the gap between the front and rear side covers), and the tape 910 on the left side of the carton extends from the left side of the carton, then the carton is driven to continue moving. Since the tape 910 is stuck to the carton, the tape 910 moves with the carton, causing the tape 910 extending from the left side of the carton to move below the push block 903. Then the second electric push rod 915 continues to extend, and the second electric push rod 915 drives the extrusion seat 916 to approach the top of the vertical rod 905 until the extrusion slope is in contact with the second pressure slope. Then the second electric push rod 915 continues to drive the extrusion seat 916 to move. Through the extrusion slope pressing the second pressure slope, the vertical rod 905... 05 drives the push block 903 downwards, and the vertical rod 905 moves downwards, guided by the guide sleeve 906. Simultaneously, the first spring 908 is stretched, and the push block 903 moves downwards, pressing the adhesive tape 910 extending from the left side of the carton, causing this portion of the tape 910 to adhere to the top left side wall of the carton, thus compacting the tape 910 on the top left side of the carton. After this side pressure, the second electric push rod 915 retracts, separating the pressing seat 916 from the vertical rod 905. Through the elastic force of the first spring 908, the vertical rod 905 and the push block 903 move upwards to reset. Then, the carton continues to move to the left, pulling the adhesive tape... Tape 910 is unwound on roller 909 and, with the pressing action of pressure block 902, adheres to the top of the carton where it needs to be sealed. The sealing process continues until the left side of the push block 903, which moves to the right side of the carton, is reached. Then, the heating element 918 melts the tape 910, separating the tape 910 adhered to the carton and located below the push block 903 from the tape 910 below the pressure block 902. Then, the second electric push rod 915 extends, driving the push block 903 to move downward, pressing the tape 910 below the push block 903 against the right side of the top of the carton, thus completing the sealing and packaging of the carton.

[0052] After sealing and packaging, the second electric push rod 915 retracts, returning to its original position. Figure 9 As shown, the sealing mechanism 9, through the elastic force of the second spring 914, also returns to its original position. Figure 9As shown, it is waiting for the sealing and packing process of the next carton.

[0053] The above design enables the sealing and packaging of the carton, and the application of tape 910 to the side of the carton where sealing is required.

[0054] like Figure 6-7 As shown, as a preferred technical solution, the compaction mechanism 10 includes a third electric push rod 1001 fixedly installed on the inner wall of the top of the cover 6. The output shaft end of the third electric push rod 1001 is fixedly installed with a carrier 1002, and a pressure roller 1003 is rotatably installed on the carrier 1002.

[0055] When sealing and packing the carton, the position where the tape 910 is pasted on the top of the carton passes under the compaction mechanism 10 to compact the tape 910. With the downward pressure of the pressure block 902, multiple compaction is achieved, which can effectively eliminate air bubbles at the tape 910 pasting point and ensure the pasting effect of the tape 910.

[0056] The compaction mechanism 10 operates as follows: the sealed carton enters below the pressure roller 1003, and the third electric push rod 1001 drives the carrier 1002 and the pressure roller 1003 to move downward together. The pressure roller 1003 presses the carton to the adhesive tape 910 pasting position. The carton is conveyed and moves about the pressure roller 1003 so that the adhesive tape 910 pasting position passes under the pressure roller 1003, thus completing the compaction.

[0057] The present invention has been described in detail above with reference to specific embodiments. However, the present invention is not limited to the above-described embodiments. Regardless of any changes in shape or structure, as long as they do not depart from the principle and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but all such changes and modifications fall within the protection scope of the present invention. The protection scope of the present invention is defined by the appended claims.
