[0042] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0043] like Figure 1-3 As shown, the utility model provides a technical solution of a double-station liquid packaging machine: a double-station liquid packaging machine, comprising a body 1 and a material bin 3 for feeding installed on the upper end of the body 1, a lower material bin 11 is arranged on the other side of the body 1, and a control box 4 is installed on one side of the upper end of the body 1, a bag placing opening is provided on the other side of the upper end of the body 1, and a bag storage mechanism 2 is installed inside the body 1 just below the bag placing opening, the bag storage mechanism 2 comprises a supporting frame 21 installed at the top end of the body 1 corresponding to below the bag placing opening, two bag taking openings 23 are provided on the upper surface of the supporting frame 21, and a plurality of vertical rods 22 are vertically arranged on the upper surface of the supporting frame 21 at the outer sides of the two bag taking openings 23, a bag storage bin is formed above each bag taking opening 23 by a plurality of vertical rods 22, a bag storage bin is formed above each bag taking opening 23, two bag storage bins are formed on the supporting frame 21, and the staff can directly stack the packaging bags in the two bag storage bins through the bag placing opening;

[0044] like Figure 3As shown, a mounting seat 28 is installed on the inner side wall of the machine body 1, and a turning cylinder 27 is installed on the top of the mounting seat 28. The output end of the turning cylinder 27 is connected to a bag taking cylinder 26, and the telescopic end of the bag taking cylinder 26 is connected to a bag taking plate 24. Two groups of bag taking suction cups 25 are symmetrically installed at both ends of the bag taking plate 24, and each group of bag taking suction cups 25 has two, and each group of bag taking suction cups 25 corresponds to each bag taking opening 23 respectively. During the working process, the bag taking cylinder 26 is controlled to extend, thereby pushing the bag taking plate 24 to move up to just below the bag taking opening 23, and then the two groups of bag taking suction cups 25 on the bag taking plate 24 work to synchronously adsorb the packaging bags in the two bag storage bins respectively. After the two groups of bag taking suction cups 25 are respectively adsorbed to the packaging bags at the bottom of the bag storage bin, the bag taking cylinder 26 is controlled to retract. Thereby, the packaging bag at the bottom of the bag storage bin is taken out from the bag taking opening 23, and then the flipping cylinder 27 is controlled to work, driving the bag taking plate 24 to flip ninety degrees, thereby flipping the two packaging bags on the two groups of bag taking suction cups 25 from a horizontal state to a vertical state, which is convenient for the bag taking and transfer of the first bag clamping mechanism 6. It should be added that the bag taking suction cups 25 can be adjusted in position on the bag taking plate 24 through the cooperation of the connecting screw and the bolt, that is, the distance between the two bag taking suction cups 25 can be adjusted, so as to facilitate the taking out of packaging bags of different sizes. Secondly, the bag taking opening 23 is slightly smaller than the packaging bag, which is convenient for carrying the packaging bag so that it will not fall from the bag taking opening 23. Moreover, the internal space of the bag storage bin is larger than the packaging bag, which is convenient for the stacking of the packaging bag. The stacked packaging bag is just above the bag taking opening 23.

[0045] like Figure 4-8As shown, two groups of positioning mechanisms 8 are installed in parallel on one side of the body 1 adjacent to the bag storage mechanism 2. The two groups of positioning mechanisms 8 have the same structure. The positioning mechanism 8 includes a fixing frame 81 installed at the top of the body 1. A limiting slide rail 82 is installed on the inner front end of the fixing frame 81. Two fixing plates 1 85 and two fixing plates 2 86 are slidably connected to the limiting slide rail 82. The two fixing plates 1 85 and the fixing plates 2 86 are slidably arranged on the limiting slide rail 82 in a staggered manner. A pneumatic finger 88 is connected to the front end of each fixing plate 1 85 and the fixing plate 2 86. The rear sides of the two groups of positioning mechanisms 8 are fixed to the body 1 through an adjusting mechanism 1. The adjusting mechanism 1 includes an adjusting motor 2 83 installed at the top center of the fixing frame 81 and an adjusting rotating rod 2 84 connected to the output end of the adjusting motor 2 83. The adjusting rotating rod 2 84 Two ends of the lower surface of are rotatably connected to two adjusting connecting rods 2 841, and the other ends of the two adjusting connecting rods 2 841 are rotatably connected to one end of one of the fixing plates 1 85 and one of the fixing plates 2 86 respectively. The adjusting mechanism 1 also includes two connecting plates 3 87, one end of the two fixing plates 1 85 is connected through one of the connecting plates 3 87, and one end of the two fixing plates 2 86 is connected through the other connecting plate 3 87. Since the two fixing plates 1 85 and the two fixing plates 2 86 are slidably arranged on the limiting slide rail 82 in a staggered manner, when the fixing plates 1 85 and the fixing plates 2 86 are adjusted by the adjusting mechanism 1, the distance between the adjacent fixing plates 1 85 and the fixing plates 2 86 can be adjusted, thereby adjusting the distance between the two pneumatic fingers 88, so as to adapt to the clamping operation of packaging bags of different sizes;

[0046] The above further elaboration on the operation of the regulating mechanism 1 is as follows:

[0047] When it is necessary to adjust the spacing between the two groups of pneumatic fingers 88 on one of the positioning mechanisms 8, the adjusting motor 2 83 is controlled to rotate in the forward direction, so that it drives the adjusting rotating rod 2 84 to rotate, and the adjusting rotating rod 2 84 will push the two adjusting connecting rods 2 841 to rotate. Therefore, the two adjusting connecting rods 2 841 will respectively push one of the fixing plates 1 85 and the fixing plate 2 86 to move linearly along the limiting slide rail 82. Under the connection effect of the connecting plate 3 87, when one of the fixing plates 1 85 and the fixing plate 2 86 moves, the other fixing plate 1 The first fixing plate 85 and the second fixing plate 86 will also move synchronously, so that the adjacent first fixing plate 85 and the second fixing plate 86 will approach each other, so that the two pneumatic fingers 88 connected to the front ends of the first fixing plate 85 and the second fixing plate 86 will approach each other, thereby adjusting the distance between each group of pneumatic fingers 88 to adapt to the clamping and fixing of smaller-sized packaging bags. Conversely, when the control and adjustment motor 83 rotates in the opposite direction, the two pneumatic fingers 88 will be adjusted away from each other to increase the distance between the two pneumatic fingers 88 to adapt to the fixing of larger-sized packaging bags.

[0048] It should be noted that the adjustment methods of the two groups of positioning mechanisms 8 are the same, and each group of positioning mechanisms 8 is provided with two groups of pneumatic fingers 88, with two in each group. Every two pneumatic fingers 88 can clamp and fix a packaging bag, respectively clamping and fixing the two sides of the packaging bag. Therefore, during processing, the opening and filling operations of the two packaging bags can be operated synchronously.

[0049] like Figure 7 As shown, a filling mechanism is installed on the inner side of the body 1 above one of the positioning mechanisms 8. The filling mechanism includes a filling cylinder 89 installed on the inner side of the body 1. The output end of the filling cylinder 89 is connected to a filling connecting plate 891. Both ends of the filling connecting plate 891 are connected to connecting cross bars 892. A filling nozzle 893 extending between two pneumatic fingers 88 is fixed at one end of each connecting cross bar 892. Figure 3 As shown, the upper end of the filling nozzle 893 is connected to the silo 3 through the discharge pipe 31, and a feeding pump is arranged between the bottom of the silo 3 and the discharge pipe 31. The filling liquid is pumped from the discharge pipe 31 to the filling nozzle 893 by the feeding pump, and then filled into the packaging bag by the filling nozzle 893. Secondly, through the extension and retraction of the filling cylinder 89, the filling connecting plate 891 and the connecting cross bar 892 can be driven to rise or fall, thereby adjusting the height of the filling nozzle 893 penetrating into the packaging bag mouth, which is convenient for the filling operation.

[0050] like Figure 2 As shown, a bag blowing mechanism is installed above another positioning mechanism 8, and the bag blowing mechanism includes a side panel installed on the inner side of the body 1, and a blowing nozzle 10 extending between two pneumatic fingers 88 is installed at both ends of the side panel. The blowing nozzle 10 is connected to an external blowing device through an air duct. After the pneumatic fingers 88 on the positioning mechanism 8 clamp and fix the two sides of the packaging bag, air is blown through the blowing nozzle 10, and air can be blown from the bag mouth of the packaging bag to the inside of the packaging bag, thereby blowing open the bag mouth of the packaging bag, making it convenient for the subsequent filling nozzle 893 to be inserted into the bag mouth of the packaging bag to carry out the filling operation.

[0051] like Figure 5As shown, a bag sealing mechanism 9 is also installed on one side of the inner side of the body 1 near the positioning mechanism 8. The bag sealing mechanism 9 includes a positioning seat 91 symmetrically installed on the top of the inner side of the body 1. A horizontal plate 92 is installed on the top of each positioning seat 91. Bag sealing cylinders 93 are symmetrically arranged on both sides of the lower end of the horizontal plate 92. The telescopic ends of the two bag sealing cylinders 93 are connected to heat sealing plates 94. The two heat sealing plates 94 are located in corresponding positions, and the packaging bag is heat-pressed and sealed by the expansion and contraction of the bag sealing cylinders 93. When the packaging bag is filled, the two bags are clamped by the second bag clamping mechanism 7. The packaging bag filled with liquid materials is transferred to the two bag sealing mechanisms 9, and then the bag sealing mechanisms 9 are started to work. The two opposite bag sealing cylinders 93 are extended synchronously, thereby pushing the two heat sealing plates 94 to move accordingly, so as to approach the bag opening of the packaging bag, and then the bag opening of the packaging bag is heat-sealed. It should be added that the heat sealing plate 94 is a heating plate, which heats the bag opening by starting to generate heat, and then cooperates with the extrusion of the two heat sealing plates 94 to heat-seal the bag opening. The principle can adopt the existing conventional bag opening heat sealing principle.

[0052] like Figure 6 and 9 As shown, the lower end of the interior of the body 1 is provided with a first bag clamping mechanism 6 and a second bag clamping mechanism 7 for taking and placing packaging bags, corresponding to the two positioning mechanisms 8 and the bag sealing mechanism 9. The first bag clamping mechanism 6 and the second bag clamping mechanism 7 are both fixed to the lower inner position of the body 1 through a driving mechanism 5. The driving mechanism 5 includes a base 51 installed on the rear side of the interior of the body 1 and positioning slide rails 52 symmetrically installed on the upper surface of the base 51. A driving cylinder 53 is installed at the bottom of the base 51. A slide seat 54 is slidably connected to the two positioning slide rails 52. A connecting block is installed on the lower surface of the slide seat 54. The upper surface of the base 51 is provided with a connecting block. A slide groove is provided at the surface corresponding to the connection block, the bottom end of the connection block is located in the slide groove and connected to the telescopic end of the driving cylinder 53. By controlling the extension of the driving cylinder 53, the slide seat 54 can be driven by the connection block to move linearly along the positioning slide rail 52, thereby synchronously driving the first push rod 55 and the second push rod 56 to move linearly. Further, the first bag clamping mechanism 6 and the second bag clamping mechanism 7 can be synchronously controlled to move linearly under the two positioning mechanisms 8 and the bag sealing mechanism 9 and the front side of the bag storage mechanism 2, so as to facilitate the transfer of packaging bags in bag taking operations, bag blowing operations, filling operations and heat sealing operations.

[0053] like Figure 6 , Fig.10As shown, a group of first push rods 55 and a group of second push rods 56 are installed in parallel on the upper surface of the slide 54, and each group of first push rods 55 and second push rods 56 has two. One end of the first push rod 55 and the second push rod 56 are connected to the slide 54 through an adjustment mechanism 2. The adjustment mechanism 2 includes a top plate 551 and a connecting plate 1 553. The top plate 551 is installed on the upper end of the slide 54. An adjustment motor 1 552 is installed on the upper end of the top plate 551. The output end of the adjustment motor 1 552 is connected to an adjustment rotating rod 1 555. Both ends of the adjustment rotating rod 1 555 are rotatably connected to an adjustment connecting rod 1 554. One of the adjustment connecting rods 1 55 One end of the second adjusting mechanism 554 is rotatably connected to the middle of the connecting plate 553, and the first bag clamping mechanism 6 and the second bag clamping mechanism 7 can be adjusted respectively through two adjusting mechanisms 2. The second bag clamping mechanism 7 includes a vertical plate 2 71 connected to one end of two first push rods 55 and a positioning plate 76 slidably arranged on the two first push rods 55. Another adjusting link 554 in the second adjusting mechanism 554 is rotatably arranged at the rear bottom end of the positioning plate 76. The spacing between the front clamping member 75 and the rear clamping member 74 and the spacing between the front bag clamping sucker 64 on the top of the vertical plate 62 and the front bag clamping sucker 64 on the rear vertical rod 63 can be adjusted through the adjusting mechanism 2, as follows:

[0054] When adjustment is needed, by controlling the adjustment motor 552 to rotate in the opposite direction, the adjustment rod 555 will rotate and push the two adjustment links 554 to move in the opposite direction. At this time, one of the adjustment links 554 will push the connecting plate 553 to move away from the adjustment rod 555. When moving, the connecting plate 553 will drive the vertical plate 71 to approach the positioning plate 76 through the two first push rods 55. At the same time, the other adjustment link 554 will push the positioning plate 76 along the surface of the two first push rods 55 toward the vertical plate 76. 1 is brought closer, thereby, the distance between the second upright plate 71 and the positioning plate 76 can be reduced, so that the rear clamping member 74 at the top of the second upright plate 71 and the front clamping member 75 at the top of the positioning plate 76 can be brought closer to each other, thereby clamping the packaging bag; conversely, when the clamping of the packaging bag needs to be released, the regulating motor 1 552 is rotated forward to drive the second upright plate 71 and the positioning plate 76 to move in the opposite direction, thereby increasing the distance between the two, so that the rear clamping member 74 and the front clamping member 75 can be moved away from each other, thereby releasing the clamping of the packaging bag.

[0055] like Fig. 9 and 10As shown, the first bag clamping mechanism 6 includes a connecting plate 2 61 connected to one end of two second push rods 56 and two rear uprights 63 connected at the front side of the machine body 1 through a telescopic cylinder. A vertical plate 1 62 is vertically mounted on one end of the connecting plate 2 61. Front bag clamping suction cups 64 are mounted on both sides of the top of the vertical plate 1 62 and on the two rear uprights 63. The front bag clamping suction cups 64 on the top of the vertical plate 1 62 and the front bag clamping suction cups 64 on the rear uprights 63 are in corresponding positions. It should be supplemented that the front bag clamping suction cups 64 on the top of the vertical plate 1 62 and the front bag clamping suction cups 64 on the rear uprights 63 can be adjusted in height by bolts and connecting rods.

[0056] When the first bag clamping mechanism 6 is adjusted by the adjusting mechanism 2, the adjusting motor 1 552 of the adjusting mechanism 2 is controlled to rotate in the opposite direction, and the front bag clamping suction cup 64 on the top of the vertical plate 1 62 can be controlled by the same principle to drive the packaging bag to approach the rear vertical pole 63, and then the telescopic cylinder connected to the rear vertical pole 63 is extended to push the rear vertical pole 63 to approach the vertical plate 1 62, so that the front bag clamping suction cup 64 on the rear vertical pole 63 is close to the rear side of the packaging bag, and then the rear side of the packaging bag is adsorbed by the front bag clamping suction cup 64 on the rear vertical pole 63. At the same time, The two groups of pneumatic fingers 88 on the first positioning mechanism 8 will clamp the two sides of the packaging bag, and then the telescopic cylinder will retract, and the adjusting mechanism 2 will drive the first bag clamping mechanism 6 to reset. During the resetting process, the front bag clamping suction cup 64 on the rear vertical rod 63 and the front bag clamping suction cup 64 on the vertical plate 1 62 will release the adsorption of the two side surfaces of the packaging bag, and during the resetting process, the two side surfaces of the packaging bag can be further pulled to open the bag mouth of the packaging bag. At this time, the blowing nozzle 10 works to blow air at the bag mouth of the packaging bag, thereby opening the bag mouth of the packaging bag and facilitating the subsequent filling operation of the packaging bag.

[0057] like Figure 9-10 As shown, the second bag clamping mechanism 7 also includes a rear cross bar 72 fixedly mounted on the top of the positioning plate 76, and a plurality of rear clamping members 74 are mounted on the rear cross bar 72. A front cross bar 73 is mounted on the top of the second vertical plate 71, and a plurality of front clamping members 75 corresponding to the rear clamping members 74 are mounted on the front cross bar 73. Every two rear clamping members 74 and the corresponding two front clamping members 75 form a group of bag clamping components. It should be noted that, with the center of the front cross bar 73 and the rear cross bar 72 as the boundary, two groups of bag clamping components are respectively arranged at both ends, namely, the bag clamping component 1 and the bag clamping component 2. The bag clamping component 1 and the bag clamping component 2 can clamp and fix two packaging bags respectively. Secondly, the front clamping member 75 and the rear clamping member 74 can slide and adjust the position on the front cross bar 73 and the rear cross bar 72, and are fixed by bolts, so as to facilitate the adjustment of the spacing between the two front clamping members 75 and the rear clamping member 74 according to the different sizes of the packaging bags.

[0058] The working principle of the utility model is: the specific working steps of the double-station liquid packaging machine of this design are as follows:

[0059] Bag placing operation: The staff can directly stack the packaging bags in the two bag storage bins through the bag placing opening. The two bag storage bins can store multiple packaging bags at the same time.

[0060] Bag taking operation: When taking bags, the bag taking cylinder 26 under the bag storage mechanism 2 extends out to push the bag taking plate 24 to move up to the position just below the bag taking opening 23, and then the two groups of bag taking suction cups 25 work to synchronously adsorb the packaging bags in the two bag storage bins. After the two groups of bag taking suction cups 25 adsorb the packaging bags at the bottom of the bag storage bins, the bag taking cylinder 26 is controlled to retract, and the packaging bags at the bottom of the bag storage bins are taken out from the bag taking opening 23. Then the flipping cylinder 27 is controlled to work to drive the bag taking plate 24 to flip 90 degrees, thereby flipping the two packaging bags on the two groups of bag taking suction cups 25 from a horizontal state to a vertical state.

[0061] The first and second bag clamping mechanisms 7 are moved synchronously by extending the driving mechanism 5, so that the front bag clamping suction cup 64 on the top of the vertical plate 1 62 of the first bag clamping mechanism 6 corresponds to the packaging bag fixed by the suction cup 25 for bag taking. At this time, the bag clamping assembly 1 and the bag clamping assembly 2 on the second bag clamping mechanism 7 are respectively located directly below the two positioning mechanisms 8, and then the adjusting mechanism 2 works to adjust the front bag clamping suction cup 64 on the vertical plate 1 62 to approach the packaging bag on the bag taking suction cup 25. After the front bag clamping suction cup 64 is attached to the packaging bag, the front bag clamping suction cup 64 is controlled to adsorb the packaging bag, and then the suction of the bag taking suction cup 25 on the packaging bag is released, so that the fixation of the packaging bag is transferred from the bag taking suction cup 25 to the front bag clamping suction cup 64, and then the adjusting mechanism 2 is reset to control the front bag clamping suction cup 64 on the vertical plate 1 62 to drive the packaging bag away from the bag taking suction cup 25, thereby completing the bag taking work.

[0062] Bag opening operation: The driving mechanism 5 is reset to make the front bag clamping suction cup 64 on the vertical plate 1 62 drive the bag to be transferred to the bottom of the first positioning mechanism 8 (i.e., the bottom of the blowing nozzle 10). At the same time, the bag clamping assembly 1 and the bag clamping assembly 2 of the second bag clamping mechanism 7 are respectively located under the second positioning mechanism 8 and the bag sealing mechanism 9. Furthermore, by adjusting the mechanism 2 and the telescopic cylinder on the rear vertical pole 63, the bag fixed by the front bag clamping suction cup 64 on the top of the vertical plate 1 62 and the front bag clamping suction cup 64 on the rear vertical pole 63 are controlled to approach each other until The front bag clamping suction cup 64 on the rear vertical pole 63 contacts the rear side of the packaging bag, and then the controller sucks the rear side of the packaging bag. At the same time, the two groups of pneumatic fingers 88 on the first positioning mechanism 8 directly above the packaging bag will clamp the two sides of the packaging bag, and then the telescopic cylinder will retract, and the adjustment mechanism 2 will drive the first bag clamping mechanism 6 to reset, and the front bag clamping suction cup 64 on the rear vertical pole 63 and the front bag clamping suction cup 64 on the vertical plate 1 62 will release the suction on the two sides of the packaging bag, and the blowing nozzle 10 will work to blow air on the bag mouth of the packaging bag, so that the bag mouth of the packaging bag can be opened, which is convenient for the subsequent filling operation of the packaging bag;

[0063] Bag filling operation: after the front bag clamping suction cup 64 on the first bag clamping mechanism 6 releases the suction fixation on the bag, the driving mechanism 5 extends out again to operate, so that the first bag clamping mechanism 6 moves to the bag taking suction cup 25 again, and the bag taken out again from the bag taking suction cup 25 is adsorbed and transferred. At the same time, the bag clamping component 1 on the second bag clamping mechanism 7 will be located below the first positioning mechanism 8, that is, it just corresponds to the two bags after the bag mouth is opened, and the bag clamping component 2 is just located below the second positioning mechanism 8. Then, the second bag clamping mechanism 7 is adjusted by the adjustment mechanism 2, so that the rear clamping piece 74 on the top of the second vertical plate 71 and the front clamping piece 75 on the top of the positioning plate 76 are close to each other, and the two sides of the opened bag clamped by the two groups of pneumatic fingers 88 on the first positioning mechanism 8 are clamped and fixed. Then, the two groups of pneumatic fingers 88 on the first positioning mechanism 8 release the clamping of the bag.

[0064] Furthermore, the driving mechanism 5 retracts and resets to drive the second bag clamping mechanism 7 to reset. Thus, the bag clamping assembly drives the two opened packaging bags to move to the bottom of the second positioning mechanism 8 (i.e., below the filling nozzle 893). At this time, the first bag clamping mechanism 6 clamps the other two packaging bags again and transfers them to the bottom of the first positioning mechanism 8. The two groups of pneumatic fingers 88 on the first positioning mechanism 8 are used to open the new packaging bags again.

[0065] In addition, the two groups of pneumatic fingers 88 on the second positioning mechanism 8 work to clamp and fix the two sides of the two opened packaging bags on the bag clamping assembly 1, and then the filling nozzle 893 works to fill the two opened packaging bags with materials. After the packaging bags are filled, the two new packaging bags under the first positioning mechanism 8 in the previous order also complete the opening operation;

[0066] Then the driving mechanism 5 works again, driving the first bag clamping mechanism 6 to take and transfer the packaging bags on the bag taking suction cup 25 again, and the bag clamping component 1 on the second bag clamping mechanism 7 will transfer the two packaging bags that have been opened in the previous order to the bottom of the second positioning mechanism 8 for filling operation, and the bag clamping component 2 will transfer the two filled packaging bags to the bottom of the bag sealing mechanism 9, and the bag sealing mechanism 9 will be used to seal the two filled packaging bags. After the packaging bags are sealed, the bag clamping component 2 will release the clamping, so that the filled and sealed packaging bags fall into the lower material bin 11 below, and slide from the lower material bin 11 to the collection frame outside the machine body 1;

[0067] By repeating the above operations, the packaging bags can be continuously and uninterruptedly removed, transferred, opened, filled and sealed, and each operation is performed on two packaging bags simultaneously, further improving the packaging bag filling efficiency.

[0068] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
