[0030] The vacuum heat-sealing mechanism provided by the present utility model can be applied to a bottle packaging machine or other packaging equipment. The vacuum heat-sealing mechanism integrates a vacuum pumping device, a material-feeding conveying device 130, a bag-opening assembly 140 and a heat-sealing assembly 150. Thus, the processes of bag loading, bag opening, vacuum pumping, heat sealing and bag discharging can be completed at the vacuum heat-sealing mechanism, which can make the overall layout of the bottle packaging machine or other packaging equipment more compact, is beneficial to reducing the overall size and floor area. In addition, the vacuum heat-sealing mechanism has stronger independence and can be set as an independent whole. It can be applied to the bottle packaging machine and also to the packaging equipment of other products. In addition, it can also be used for semi-automatic packaging. Specifically, in semi-automatic packaging, the staff can complete bottle boxing, place the bag on the material-feeding conveying device 130, and put the box into the bag.

[0031] In the specific implementation process, the material-feeding conveying device 130 can move horizontally to adjust the position of the bag, so as to adjust the heat-sealing position of the bag in the horizontal direction.

[0032] Refer to Figure 1 and Figure 2, according to some embodiments of the present utility model, the bag opening assembly 140 includes an upper adsorption module 141, a lower adsorption module 142 and a second driving device 143 which are oppositely arranged. The second driving device 143 is installed on the lower shell 112, and the second driving device 143 can drive the upper adsorption module 141 and the lower adsorption module 142 to move relatively closer or farther away. The heat sealing assembly 150 includes a third driving device 151, an upper heat sealing pressing plate 152 and a lower heat sealing pressing plate 153 which are oppositely arranged. The third driving device 151 is installed on the lower shell 112, and the third driving device 151 can drive the upper heat sealing pressing plate 152 and the lower heat sealing pressing plate 153 to move relatively closer or farther away. Through the above arrangement, the bag opening assembly 140 can complete the task of opening the bag mouth of the bag on the feeding conveying device 130, and the heat sealing assembly 150 can complete the heat sealing of the bag mouth of the bag on the feeding conveying device 130.

[0033] Refer to Figure 1 and Figure 2, according to some embodiments of the present utility model, the second driving device 143 is drivingly connected with a first connecting frame 144. The upper adsorption module 141 and the lower heat-sealing pressing plate 153 are installed on the first connecting frame 144, and the lower adsorption module 142 is fixedly installed on the lower housing 112. The third driving device 151 is drivingly connected with a second connecting frame 154, and the upper heat-sealing pressing plate 152 is installed on the second connecting frame 154. With the above arrangement, during the bag-opening process, the second driving device 143 first drives the upper adsorption module 141 to descend close to the lower adsorption module 142, so that the upper adsorption module 141 and the lower adsorption module 142 clamp the bag mouth of the closed packaging bag, enabling the upper adsorption module 141 and the lower adsorption module 142 to correspondingly adhere to and adsorb the upper and lower side walls of the bag mouth of the packaging bag. Then, the second driving device 143 drives the upper adsorption module 141 to ascend, so that the upper and lower side walls of the bag mouth of the packaging bag are separated and opened to wait for the product to be packaged to be loaded. When the upper adsorption module 141 opens the bag mouth of the packaging bag, the upper surface of the lower heat-sealing pressing plate 153 is not higher than the adsorption surface of the lower adsorption module 142. After the product is loaded into the packaging bag, the upper adsorption module 141 and the lower adsorption module 142 stop adsorbing the packaging bag. The second driving device 143 can drive the lower heat-sealing pressing plate 153 to ascend, and the third driving device 151 can drive the upper heat-sealing pressing plate 152 to descend. Thus, the lower heat-sealing pressing plate 153 and the upper heat-sealing pressing plate 152 can approach each other to heat-seal the bag mouth of the packaging bag. Among them, through the third driving device 151 and the second driving device 143, the heat-sealing position of the bag mouth of the packaging bag in the height direction can be adjusted, so that the bag mouth of the packaging bag can be heat-sealed at the middle height position, the lower bag wall position, the upper bag wall position or other positions. Coupled with the fact that the feeding and conveying device 130 can move and adjust the heat-sealing position of the bag in the horizontal direction, it can thus meet the heat-sealing requirements of different heat-sealing positions of different packaging bags. And because the movement of the lower heat-sealing plate shares the second driving device 143 with the upper adsorption module 141, there is no need to independently configure a driving device for the lower heat-sealing plate, achieving a streamlined structure, reducing costs, and reducing the installation space required for the bag-opening assembly 140 and the heat-sealing assembly 150, improving the utilization rate of the internal space of the housing assembly 110, which is beneficial to reducing the size of the housing assembly 110.

The second driving device 143 and the third driving device 151 are installed on the mounting plate 162, and the first connecting frame 144 and the second connecting frame 154 are located below the mounting plate 162. With the above arrangement, the installation space required for the bag-opening assembly 140 and the heat-sealing assembly 150 can be reduced, the utilization rate of the internal space of the housing assembly 110 can be improved, and it is beneficial to reducing the size of the housing assembly 110.

[0035] Refer to Figure 1 andFigure 2 , according to some embodiments of the present utility model, the second driving device 143 is drivingly connected with a first gear, the first gear is drivingly engaged with a first rack 145, the first rack 145 is slidably disposed through the mounting plate 162 in the up and down direction, the first connecting frame 144 is mounted on the first rack 145, the third driving device 151 is drivingly connected with a second gear 155, the second gear 155 is drivingly engaged with a second rack 156, the second rack 156 is slidably disposed through the mounting plate 162 in the up and down direction, and the second connecting frame 154 is mounted on the second rack 156. With the above arrangement, the lifting of the upper adsorption module 141, the upper heat-sealing pressing plate 152 and the lower heat-sealing pressing plate 153 can be realized.

[0036] It should be noted that other transmission methods may also be adopted between the second driving device 143 and the first connecting frame 144. For example, the second driving device 143 includes a motor, a transmission sleeve is sleeved on the output shaft of the motor, the transmission sleeve is in threaded transmission with the output shaft, the transmission sleeve is vertically arranged, and the transmission sleeve is connected with the first connecting frame 144. Similar arrangements may also be adopted between the third driving device 151 and the second connecting frame 154, which will not be elaborated here.

Since the above-mentioned vacuum heat-sealing mechanism integrates a vacuum pumping device, a feeding and conveying device 130, a bag-opening assembly 140, and a heat-sealing assembly 150, the processes of bagging, bag-opening, vacuum pumping, heat-sealing, and bag discharging can be completed at the vacuum heat-sealing mechanism, which can make the overall layout of the bottle packaging machine more compact and is beneficial to reducing the overall size of the bottle packaging machine.

[0038] Refer to Figure 1 , Figure 3 and Figure 4 , according to some embodiments of the present utility model, it includes a machine frame 200, the lower shell 112 is mounted on the machine frame 200, the first driving device 120 is mounted on the machine frame 200, and the upper shell 111 is mounted below the first driving device 120. Thus, the vertical projection of the first driving device 120 overlaps with the vertical projection of the upper shell 111, reducing the floor area of the entire bottle packaging machine.

[0039] Refer to Figure 1 , Figure 3 and Figure 4, according to some embodiments of the present utility model, it includes an upper bagging mechanism 300.

The moving device 310 is located on the right side of the housing assembly 110. The bag suction device 320 is located on the left side of the moving device 310. A bag placing station 210 is arranged on the front side or the rear side of the housing assembly 110. After the first driving device 120 drives the upper shell 111 to rise away from the lower shell 112, the moving device 310 can drive the bag suction device 320 to move between the bag placing station 210 and the feeding conveyor 130. With the above layout, the moving range of the bag suction device 320 overlaps with the vertical projection of the bag placing station 210 and the upper shell 111. The moving device 310 is above the discharging position of the vacuum heat-sealing mechanism. Thus, the layout of the bottle packaging machine can be made more compact, which is beneficial to reducing the size and floor area.

[0040] Referring to Figure 1 , Figure 3 and Figure 4 , according to some embodiments of the present utility model, a discharging conveyor 400 is arranged on the right side of the lower shell 112. The discharging conveyor 400 is used to receive the packaging bags conveyed by the feeding conveyor 130. The discharging conveyor 400 is located below the moving device 310. Thus, the products that have completed packaging can be conveyed out through the discharging conveyor 400. The overlapping layout of the discharging conveyor 400 and the moving device 310 can make the layout of the bottle packaging machine more compact, which is beneficial to reducing the size and floor area.

[0041] Referring to Figure 1 , Figure 3 and Figure 4 , according to some embodiments of the present utility model, a bottle boxing mechanism 500 and a box bagging mechanism 600 are arranged on the frame 200 in sequence from left to right.

The upper bottle component can be used to put the bottles into the box at the bottle boxing station 230 and arrange them neatly. After the bottles are boxed, the belt conveyor pushes the box to the bag opening device, so as to push the box into the packaging bag with the bag mouth opened, and complete the box bagging. With the above settings, the structures of the bottle boxing mechanism 500 and the box bagging mechanism 600 are relatively simple.

[0043] Referring toFigure 1 , Figure 3 and Figure 4 , in some other embodiments, the bottle boxing mechanism 500 and the box bagging mechanism 600 can also adopt other settings. For example, the bottle boxing mechanism 500 includes a bottle supply component 510, a box covering component 520, and a bottle pushing component 530. A bottle row arranging station 220 and a boxing station 230 are provided on the frame 200. The bottle supply component 510 conveys a whole row of bottles to the bottle row arranging station 220, and then the bottle pushing component 530 pushes the row of bottles at the bottle row arranging station 220 to the boxing station 230, so as to neatly arrange multiple rows of bottles at the boxing station 230. Then, the box covering component 520 covers the box on the multiple rows of bottles at the boxing station 230. Then, the bottle pushing component 530 pushes the box and the bottles inside the box together to the box bagging mechanism 600. After the box bagging mechanism 600 flips the box and the bottles inside the box so that the opening of the box faces upward, the box bagging mechanism 600 then pushes the box to the bag opening component 140 to complete the bagging of the box. By adopting the above settings, the efficiency of bottle boxing can be improved, and further the packaging efficiency of the bottle packaging machine can be improved.
