Description

Technical Field

[0001] The present application relates to the technical field of packaging bag sealing, and in particular to a packaging bag sealing device. Background Art

[0002] Currently, the packaging process of essential hygiene products in daily life, such as napkins, facial tissues, diapers and sanitary napkins, usually follows a rigorous and standardized operating procedure. The first step of this process is that the products that have been precisely measured in advance are neatly placed in pre-prepared packaging bags. This step requires a high degree of accuracy and meticulousness to ensure that the number of products in each packaging bag meets the established standards and meets the needs of consumers.

[0003] Next, these bags filled with products will pass through professional sealing equipment, usually called a sealer, to seal the bag opening. Sealing is a key link in the packaging process, which is directly related to the hygienic safety of the product and the stability of subsequent transportation and storage. The sealer heats the sealing strip and fits it tightly to the bag opening to form a firm seal line to prevent the intrusion of air, moisture or microorganisms, thereby maintaining the quality of the product and extending its shelf life.

[0004] However, traditional sealing machines often separate the two crucial steps of sealing and cutting. This separate design brings many inconveniences in actual operation. Specifically, every time a packaging bag is sealed, it is necessary to wait for a while before cutting, or manually transfer the sealed packaging bag to the cutting equipment. These extra waiting and conversion times not only extend the cycle of the entire production process, but also reduce the overall production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0021] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0022] The packaging bag sealing device according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0023] like Figure 1-Figure 3 As shown, the packaging bag sealing device of the embodiment of the present application may include a support frame 10, two columns 20, a support plate 30, a retractable mechanism 40, a lower sealing mechanism 50, an upper sealing mechanism 60 and a cutting device 70.

[0024] The two columns 20 are arranged side by side and vertically in the support frame 10 , and first racks 21 are respectively provided on opposite surfaces of the two columns 20 .

[0025] The support plate 30 is movably disposed on the two pillars 20 , and an opening 31 is formed on the support plate 30 for the first rack 21 to pass through.

[0026] The retractable mechanism 40 is disposed on the top wall of the support frame 10, and the output end of the retractable mechanism 40 is fixedly connected to the support plate 30, wherein the retractable mechanism 40 is used to drive the support plate to drive the cutting device 70 and the upper sealing mechanism 60 to move synchronously up and down.

[0027] It should be noted that the retractable mechanism 40 described in this embodiment may be a cylinder, a hydraulic cylinder or an electric retractable rod.

[0028] The lower sealing mechanism 50 is fixedly arranged on the bottom wall of the support frame 10, and the upper sealing mechanism 60 is arranged on the support plate 30 and is located above the lower sealing mechanism 50. The cutting device 70 is arranged on the support plate 30 and is intermittently connected to the first rack 21.

[0029] Specifically, when daily hygiene products (such as napkins, facial tissues, diapers or sanitary napkins, etc.) are continuously sub-packaged on an assembly line, the hygiene products are usually first arranged side by side in a long tube packaging bag.

[0030] When it is necessary to sub-package and seal the long tube packaging bags containing daily hygiene products, the relevant staff first needs to pass the packaging bags containing daily hygiene products between the lower sealing mechanism 50 and the upper sealing mechanism 60, and then control the output end of the retractable mechanism 40 to extend and push the support plate 30 to drive the upper sealing mechanism 60 and the cutting device 70 to move downward synchronously, and the lowered upper sealing mechanism 60 first presses the sealing part of the packaging bag on the lower sealing mechanism 50, and then seals the part of the packaging bag to be sealed.

[0031] As the support plate 30 drives the upper sealing mechanism 60 and the cutting device 70 to continue to move downward, the cutting device 70 contacts the fixed first rack 21. At this time, the downwardly moving cutting device 70 is driven by the first rack 21 and cuts the sealing part of the packaging bag to separate two adjacent packaging bags containing daily hygiene products.

[0032] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 1 As shown, the lower sealing mechanism 50 may include a lower sealing mold 51 and a first heating rod 52, wherein the lower sealing mold 51 is fixedly disposed on the bottom wall of the support frame 10 and is located between the two columns 20, and a first cutting edge 501 is opened in the middle of the top wall of the lower sealing mold 51.

[0033] The first heating rod 52 is disposed in the lower sealing mold 51 , wherein the first heating rod 52 is connected to an external power source.

[0034] It is understandable that the staff can connect the first heating rod 52 to an external power source and heat the lower sealing mold 51 through the first heating rod 52, so that the lower sealing mold 51 heats the bottom of the bag opening of the packaging bag to achieve the purpose of sealing.

[0035] Further, in one embodiment of the present application, Figure 1 and Figure 2 As shown, the upper sealing mechanism 60 may include an upper sealing mold 61 , a second heating rod 62 , two first guide pillars 63 and two first springs 64 .

[0036] The upper sealing mold 61 is disposed between the support plate 30 and the lower sealing mold 51 , and a second cutting edge 601 corresponding to the first cutting edge 501 is formed on the bottom wall of the upper sealing mold 61 .

[0037] The second heating rod 62 is arranged in the upper sealing mold 61, wherein the second heating rod 62 is connected to an external power supply, and two first guide columns 63 are arranged side by side and vertically on the top wall of the upper sealing mold 61, and the top ends of the two first guide columns 63 respectively penetrate the support plate 30.

[0038] The two first springs 64 are respectively sleeved on the corresponding first guide pillars 63 , and one end of the first spring 64 is fixedly connected to the support plate 30 , and the other end of the first spring 64 is fixedly connected to the upper sealing mold 61 .

[0039] It is understandable that the staff can connect the second heating rod 62 to an external power source and heat the upper sealing mold 61 through the second heating rod 62, so that the upper sealing mold 61 heats the top of the bag opening of the packaging bag to achieve the purpose of sealing.

[0040] Further, in one embodiment of the present application, Figure 1-Figure 3 As shown, the cutting device 70 may include a cutting blade 71 , two supporting mechanisms 72 and two transmission mechanisms 73 .

[0041] The cutting knife 71 is movably arranged in the second cutting edge 601 , two supporting mechanisms 72 are arranged side by side at both ends of the cutting knife 71 , and the bottom of the supporting mechanism 72 is detachably connected to the end of the cutting knife 71 , and the top of the supporting mechanism 72 passes through the supporting plate 30 .

[0042] The two transmission mechanisms 73 are respectively located between the corresponding support mechanisms 72 and the columns 20 , and are fixedly disposed on the support plate 30 . The transmission mechanisms 73 are connected to the support mechanisms 72 , and the transmission mechanisms 73 are intermittently connected to the first rack 21 .

[0043] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 1 and Figure 3 As shown, the supporting mechanism 72 may include a second guide post 721 , a baffle 722 , a second spring 723 and a second rack 724 .

[0044] One end of the second guide column 721 is detachably connected to the end of the cutting blade 71 , the other end of the second guide column 721 penetrates the support plate 30 , and a mounting groove 701 is formed at the top of the second guide column 721 .

[0045] The baffle plate 722 is sleeved and fixed on the second guide column 721 , the second spring 723 is sleeved on the second guide column 721 , and one end of the second spring 723 is fixedly connected to the baffle plate 722 , the other end of the second spring 723 is fixedly connected to the support plate 30 , and the second rack 724 is fixedly arranged in the mounting groove 701 .

[0046] Further, in one embodiment of the present application, Figure 2and Figure 3 As shown, the transmission mechanism 73 may include a bracket 731 and a gear 732 , wherein the bracket 731 is located between the corresponding second guide column 721 and the column 20 , and is fixedly disposed on the support plate 30 .

[0047] The gear 732 is rotatably disposed on the bracket 731 , and the gear 732 is meshed with the second rack 724 , and the gear 732 is intermittently meshed with the first rack 21 .

[0048] Specifically, when the packaging bag needs to be sealed, the staff first needs to connect the first heating rod 52 and the second heating rod 62 to an external power source to heat the lower sealing mold 51 and the upper sealing mold 61 .

[0049] Then, the staff controls the output end of the retractable mechanism 40 to extend and push the support plate 30 to drive the upper sealing mechanism 60 and the cutting device 70 to move downward synchronously. During the downward movement, the upper sealing mold 61 in the upper sealing mechanism 60 presses the sealing part of the packaging bag onto the lower sealing mold 51, and the upper sealing mold 61 and the lower sealing mold 51 heat and seal the sealing part of the packaging bag.

[0050] As the support plate 30 continues to move downward, the downwardly moving support plate 30 compresses the first spring 64 and drives the cutting device 70 to move downward. At this time, the gear 732 in the cutting device 70 is meshed with the first rack 21 fixedly set on the column 20. During the downward movement of the gear 732, the gear 732 is driven to rotate, and the rotating gear 732 drives the second rack 724 to push the second guide column 721 to move downward. The second guide column 721 moving downward stretches the second spring 723 and pushes the cutting knife 71 to quickly extend from the second cutting edge 601 and cut the sealing part of the packaging bag. In addition, by integrating sealing and cutting into one, not only the processing time of each packaging bag is shortened, but also the overall production efficiency is effectively improved.

[0051] Optionally, the opposing surfaces of the lower sealing mold 51 and the lower sealing mold 51 may be flat surfaces, serrated surfaces or wavy surfaces that can be plugged into each other, etc.

[0052] In summary, the packaging bag sealing equipment of the embodiment of the present application not only shortens the processing time of each packaging bag but also effectively improves the overall production efficiency by integrating sealing and cutting.
