The support 1022 can move along the guide rail 105 arranged on the base 101, so that the first sealing roller 1023 seals the sealing bag 200 to form a first sealing portion 202.

[0059] In an embodiment, the support structure 1024 can include a second sealing wheel 1026. During the sealing operation, at least the part of the sealing bag 200 currently being sealed and / or the part adjacent thereto is arranged between the second sealing wheel 1026 and the first sealing wheel 1023. During the sealing operation, the second sealing wheel 1026 supports the sealing bag 200, and the first sealing wheel 1023 and the second sealing wheel 1026 move relative to the sealing bag 200 along with the support frame 1022 under the control of the control circuit 104 and perform the roller sealing. The surface of the first sealing wheel 1023 can be provided with first lines, and the second sealing wheel 1026 can be correspondingly provided with second lines. The first lines correspond to the second lines, so that the first sealing part 202 formed has a better sealing effect. The first lines or the second lines can be, for example, dots, straight lines, S lines, or X lines, or no lines can be provided on the first sealing wheel 1023 and the second sealing wheel 1026, or lines can be provided on only one of the first sealing wheel 1023 or the second sealing wheel 1026. In this way, the first sealing part 202 with lines can be formed, and the first sealing part 202 with lines has a better sealing effect than the first sealing part 202 without lines.

[0060] In an embodiment, the support structure 1024 can include a second sealing wheel 1026. During the sealing operation, at least the part of the sealing bag 200 currently being sealed and / or the part adjacent thereto is arranged between the second sealing wheel 1026 and the first sealing wheel 1023. During the sealing operation, the second sealing wheel 1026 supports the sealing bag 200, and the first sealing wheel 1023 and the second sealing wheel 1026 move relative to the sealing bag 200 along with the support frame 1022 under the control of the control circuit 104 and perform the roller sealing. The surface of the first sealing wheel 1023 can be provided with first lines, and the second sealing wheel 1026 can be correspondingly provided with second lines. The first lines correspond to the second lines, so that the first sealing part 202 formed has a better sealing effect. The first lines or the second lines can be, for example, dots, straight lines, S lines, or X lines, or no lines can be provided on the first sealing wheel 1023 and the second sealing wheel 1026, or lines can be provided on only one of the first sealing wheel 1023 or the second sealing wheel 1026. In this way, the first sealing part 202 with lines can be formed, and the first sealing part 202 with lines has a better sealing effect than the first sealing part 202 without lines.

[0061] In an embodiment, the first sealing wheel 1023 comprises one or more first rollers 1027, and the second sealing wheel 1026 comprises one or more second rollers 1028, the first rollers 1027 and the second rollers 1028 are oppositely arranged, and during the sealing operation, the sealing bag 200 (or at least the part of the sealing bag 200 to be sealed) is arranged between the first rollers 1027 and the second rollers 1028. The first rollers 1027 can be the same size as the second rollers 1028, or the diameter of the first rollers 1027 is greater than the diameter of the second rollers 1028. For example, the first rollers 1027 have a first diameter D1, and the second rollers 1028 have a second diameter D2, and the size relationship between the first diameter and the second diameter satisfies 1≤D1:D2≤3. As shown in Figure 2 In an embodiment, the first sealing wheel 1023 comprises one first roller 1027, and when the first sealing wheel 1023 comprises a plurality of first rollers 1027, the plurality of first rollers 1027 are arranged in sequence along the sealing direction of the roller sealing structure 1021.

[0062] In an embodiment, the first sealing wheel 1023 and the support structure 1024 each have a first heating component (not shown in the figure), that is, the surface (or the inside) of the first sealing wheel 1023, the support platform 1025, and / or the second sealing wheel 1026 each has a first heating component. The first heating component can be used to heat the part of the sealing bag 200 to be sealed (the first sealing part 202) during the sealing process, for example, to provide a heating temperature of about 180-250°C, so as to better achieve roller sealing of the sealing bag 200 and improve the sealing effect of the first sealing structure 1021.

[0063] As shown in Figure 2 In an embodiment, the support platform 1025 and the second sealing wheel 1026 are both provided as the support structure 1024 to provide support when the first sealing wheel 1023 seals the sealing bag 200. For example, during the sealing operation, at least the part of the sealing bag 200 to be sealed is arranged between the second sealing wheel 1026 and the first sealing wheel 1023, and the part of the sealing bag 200 adjacent to the part to be sealed is arranged on the support platform 1025, but not limited thereto.

[0064] In addition, the roller sealing structure 1021 can further comprise one or more guide wheels 1029 and pressure adjustment structures 1030. The guide wheels 1029 and the pressure adjustment structures 1030 are arranged on the bracket 1022, and the guide wheels 1029 and the pressure adjustment structures 1030 can both provide preheating to the sealing bag 200, and the preheating temperature is lower than the heating temperature provided by the first heating component. For example, the guide wheels 1029 and the pressure adjustment structures 1030 can provide a preheating temperature of about 60-150°C. As shown in Figure 2As shown, the guide wheel 1029, the pressure adjusting structure 1030 and the first sealing wheel 1023 are sequentially arranged along the sealing direction of the roller sealing structure 1021. The guide wheel 1029 can make the bag opening of the sealing bag 200 smoothly enter the roller sealing structure 1021 and press the sealing bag 200. The pressure adjusting structure 1030 can be used to adjust the pressure between the first sealing wheel 1027 and the support structure 1024 (i.e. the support platform 1025 and / or the second sealing wheel 1026), so as to adjust the sealing effect of the first sealing part 202 in the sealing bag 200, and also can play the role of auxiliary fixing, pressing and flattening the sealing bag.

[0065] In the present application, the surface of the guide wheel 1029 can also be provided with a pattern, so as to better guide the bag opening of the sealing bag 200. In an embodiment, the pattern on the guide wheel 1029 can be different from the pattern on the first sealing wheel 1023 and the like. For example, one of them is a horizontal pattern, and the other is a vertical pattern. By cooperation of different patterns, the sealing effect can be further improved. The guide wheel 1029 can be provided with the same size as the first sealing wheel 1023 or the second sealing wheel 1026, or can be provided to be smaller than the first sealing wheel 1023 or the second sealing wheel 1026, and the present application is not limited thereto. Figure 2 As shown, the guide wheel 1029 includes a pair of rollers cooperating with each other. The roller corresponding to the first sealing wheel 1023 can be provided with the same size as the first sealing wheel 1023, and the roller corresponding to the second sealing wheel 1026 can be provided with the same size as the second sealing wheel 1026, but the present application is not limited thereto. In other embodiments, the guide wheel 1029 can include a plurality of pairs of rollers cooperating with each other, and the plurality of pairs of rollers are sequentially arranged along the sealing direction of the roller sealing structure 1021, so as to jointly guide the sealing bag 200.

[0066] In the present application, the pressure adjusting structure 1030 can include an elastic component 1041, which is a spring or a spring sheet, and the present application is not limited thereto. The pressure adjusting structure 1030 can be provided with different numbers of springs or spring sheets according to the required pressure, so as to control the tightness of the bag opening of the sealing bag 200.

[0067] As shown, Figure 2As shown, the pressure adjusting structure 1030 further comprises a support block 1042 and a connecting member 1043. The support block 1042 can be matched with the corresponding support platform 1025. The elastic member 1041 is movably arranged on the support block 1042 through the connecting member 1043. In this way, the elastic member 1041 can be adjusted to have different deformation degrees, so as to adjust the force applied to the support block 1043, and further adjust the pressing force between the support block 1043 and the corresponding support platform 1025. Further, the pressing force between the first support structure 1024 and the first sealing wheel 1023 can also be changed along with the adjustment of the pressure adjusting structure 1030 through the linkage mechanism.

[0068] It should be noted that in the present application, the first sealing wheel 1023, the support platform 1025, the second sealing wheel 1026 and the guide wheel 1029 are all arranged in a detachable structure, so as to be replaced according to needs, and replaced into the required texture.

[0069] In combination Figures 1 to 3 As shown, the flat-plate sealing structure 1031 is arranged adjacent to the roller sealing structure 1021, and is arranged in the base 101. The flat-plate sealing structure 1031 is used for sealing the sealing bag 200 to form the second sealing part 203. The flat-plate sealing structure 1031 and the roller sealing structure 1021, i.e. the first sealing part 202 and the second sealing part 203 of the sealing bag 200, have a spacing L therebetween, wherein 5cm≤L≤15cm.

[0070] In an embodiment, the flat-plate sealing structure 1031 comprises a support plate 1032 and a pressing plate 1033. The surfaces of the support plate 1032 and the pressing plate 1033 can be provided with second heating members, so as to realize hot-press sealing. In the present application, the support plate 1032 of the flat-plate sealing structure 1031 can be integrally arranged with the support platform 1025 of the roller sealing structure 1021, or can be separately arranged, and the present application is not limited thereto. In addition, it should be noted that, in order to facilitate drawing / illustration, Figure 1 and Figure 2 Only part of the elements of the flat-plate sealing structure 1031 is shown in the figure.

[0071] In combination Figures 1 to 4As shown, in the present application, the roller sealing structure 1021 utilizes the pressure between the first sealing wheel 1023 and the support structure 1024, and moves along the sealing direction relative to the sealing bag 200 under the movement of the support 1022, to realize the hot roller sealing to form the first sealing part 202, and the flat plate sealing structure 1031 utilizes the pressing force between the support plate 1032 and the pressing plate 1033, to realize the hot pressing sealing to form the second sealing part 203. Wherein, since the roller sealing structure 1021 needs to move from one side to the other side of the sealing bag 200, if the moving speed is too fast, it will lead to poor sealing effect. In the present application, the sealing time required by the roller sealing structure 1021 is greater than the sealing time required by the flat plate sealing structure 1031, or in other words, the sealing time required by the flat plate sealing structure 1031 is less than the sealing time required by the roller sealing structure 1021. For example, the sealing time of the flat plate sealing structure 1031 can be about 5 seconds, and the sealing time of the roller sealing structure 1021 can be about 10 seconds, of course, different sealing times can also be set according to the temperature provided by the heating component and the pressing force, and the present application is not limited thereto.

[0072] In an embodiment, the sealing operation of the sealing device 100 on the sealing bag 200 includes a first stage T1 and a second stage T2. In the first stage T1, the first heating component heats the sealing bag 200, and the roller sealing structure 1021 moves from one side to the other side of the sealing bag 200 to perform roller sealing on the first sealing part 202. At the same time, the flat plate sealing structure 1031 heats the sealing bag 200 to perform hot pressing sealing on the second sealing part 203.

[0073] After the first stage T1 ends, the flat plate sealing structure 1031 stops heating the sealing bag 200. That is, in the second stage T2, the flat plate sealing structure 1031 does not perform sealing operation, but still applies the pressing force to assist in supporting and positioning the sealing bag 200, so that the roller sealing structure 1021 continuously moves to the other side of the sealing bag 200 and completes the roller sealing.

[0074] In addition, in the present application, the width of the first sealing part 202 can be the same as the width of the second sealing part 203, or the width of the first sealing part 202 is greater than the width of the second sealing part 203, and the present application is not limited thereto.

[0075] In combination Figures 1 to 5As shown, the sealing bag 200 formed by sealing according to the sealing device 100 of the present application comprises a main body part 201, a first sealing part 202 and a second sealing part 203 are formed on the main body part 201 and are arranged adjacently. The first sealing part 201 is sealed by the first sealing structure 102, and the second sealing part 203 is sealed by the second sealing structure 103. The first sealing part 202 and the second sealing part 203 have a spacing L, wherein 5cm≤L≤15cm.

[0076] Of course, the sealing device has other components, which are not described here.

[0077] According to the embodiment of the present application, by simultaneously arranging the flat sealing structure and the roller sealing structure on the sealing device, two different sealing parts can be obtained by one operation on the sealing bag, and the flat sealing structure and the roller sealing structure are controlled separately, so one of the sealing structures can be selected for use, which can ensure the sealing effect of the sealing bag, ensure the appearance of the sealing bag, save operation time and improve production efficiency.

[0078] Of course, the present application can have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications shall belong to the protection scope of the claims attached to the present application.
