[0036] Among them, the steel cylinder whole plate 1 is used to organize the packaging bottles 11 so that they can be neatly conveyed to the second feeding device 8, and then the second feeding device 8 conveys the packaging bottles 11 to the first feeding device 4, and is temporarily clamped by the first feeding device 8, and then the packaging bottles 11 are pushed to the upper part of the limiting device 7 by the capping device 5, and then the packaging bottles 11 are clamped by the limiting device 7; and the bottle cap vibrating plate 2 is used to organize the bottle caps so that they can be neatly conveyed to the capping device 5, and the bottle caps are installed in the packaging bottles 11 clamped by the limiting device 7 by the capping device 5, thereby completing the capping; after the bottle caps are installed, the packaging bottles 11 are pushed to the bottom of the limiting device 7 by the capping device 5, and then the packaging bottles 11 are conveyed to the sealing device 6 by the first feeding device 4 for inflation and sealing, and then the packaging bottles 11 enter the blanking chute 12 and fall into the collecting device 9, and the packaging bottles 11 are weighed and measured by the collecting device 9, and then products of different weights are collected separately.

[0037] like Figure 3 、 Figure 4 and Figure 5 As shown, the capping device 5 includes a capping assembly 51, a feeding assembly 52 and a lifting cylinder 53. The capping assembly 51 and the feeding assembly 52 are both installed above the limiting device 7. The lifting cylinder 53 is vertically installed below the limiting device 7. The capping assembly 51 includes a capping cylinder 511 and a push block installed on the output rod of the capping cylinder 511.

[0038] Among them, the feeding assembly 52 includes a feeding cylinder 521, a limiting block 523 and a capping platform 522. The capping platform 522 is a plate with a feeding channel 524 inside. The feeding end of the feeding channel 524 is connected to the feeding track of the bottle cap vibration plate, so that the bottle cap vibration plate can neatly transport the bottle caps into the feeding channel 524. A through hole 525 is provided at the tail end of the feeding channel. The diameter of the through hole 525 corresponds to that of the feeding channel 524. The through hole 525 passes through the capping platform 7 and the frame wall plate on which the feeding assembly 52 is installed. The through hole 524 is located just above the clamping position of the limiting device 7 and is located at the push block Directly below, the pushing block is circular and its size corresponds to the through hole; the limiting block 523 is installed at the output rod of the feeding cylinder 521, and the width of the limiting block 523 corresponds to the width of the feeding channel 524, so that the limiting block 523 can move in the feeding channel, and the limiting block 523 is provided with an arc-shaped bayonet that contacts the bottle cap, and the size of the bayonet corresponds to the arc-shaped side wall of the bottle cap, so that the bottle cap can be accurately pushed above the through hole 524, and the bayonet and the arc-shaped tail end of the feeding channel 524 can fix and limit the bottle cap, so that the pressing cap assembly can accurately press the bottle cap into the packaging bottle clamped by the limiting device 7.

[0039] Among them, the feeding chute 524 is provided with a first sensor (not shown in the figure) electrically connected to the programmable controller. The first sensor is used to sense the bottle caps in the feeding chute 524 and transmit the signal to the programmable controller, so that the programmable controller controls the regular start of the capping cylinder 511 and the pushing cylinder 521, so that the bottle caps are normally transported to the bottom of the capping assembly 51 and installed in the packaging bottle 11.

[0040] like Figure 3 、 Figure 7 and Figure 8 As shown, the limiting device 7 includes a clamping claw 701 and a positioning cylinder 702 that can clamp the packaging bottle 11. The clamping claw 701 is slidably installed above the positioning cylinder 702. The clamping claw 4 is a three-claw clamp (see Figure 17 ) and is controlled by a programmable controller. A vertical channel is provided inside the positioning cylinder 702 for the bottle 11 to pass through. The output rod of the lifting cylinder 53 is opposite to the vertical channel of the positioning cylinder 702. The lifting cylinder 53 can push the bottle 11 from the lower part to the upper part of the positioning cylinder 702 along the vertical channel and make the bottleneck of the bottle 11 located in the through hole 525. After the bottle 11 reaches the upper part of the positioning cylinder 702, the clamping claw 701 can clamp the bottle, and then the bottle cap can be pressed into the bottle 11 by the capping assembly 51, thereby completing the installation of the bottle cap.

[0041] like Figure 6 、 Figure 7 and Figure 9The second feeding device 8 includes a positioning component and a conveying component. The positioning component includes a barrel 811, a second limiting plate 812, a square plate 813 and an L-shaped plate 814. The barrel 811 is vertically mounted on the frame 3 on the side of the limiting device 7. The upper port of the barrel 811 is connected to the feed pipe of the cylinder vibrating plate 1. The second limiting plate 812 is mounted below the barrel 811 and above the L-shaped plate 814. A semicircular notch is provided on the second limiting plate 812, and the diameter of the notch corresponds to the diameter of the bottle body of the packaging bottle 11. The center line of the notch is on the same vertical line as the center line of the inner hole of the barrel 811. The L-shaped plate 814 is mounted on the square plate 813 for supporting the packaging bottle 11 falling from the barrel 811, and a second sensor for sensing the packaging bottle 11 is provided on the L-shaped plate 814.

[0042] Among them, the conveying assembly includes a first feeding cylinder 821, a second feeding cylinder 822 and a third electromagnet 823 for clamping the packaging bottle 11. The first feeding cylinder 821 is installed on the square plate 813, and the second feeding cylinder 822 is installed on the output rod of the first feeding cylinder 821. The third electromagnet 823 is installed on the output rod of the second feeding cylinder 822, and the third electromagnet 13 is provided with a groove corresponding to the bottle wall of the packaging bottle 11, so as to adsorb the packaging bottle 11 into the inside. The first feeding cylinder 821 and the second feeding cylinder 822 are used to transport the third electromagnet 823 to the first feeding device 4, thereby realizing the transfer of the packaging bottle 11.

[0043] like Figure 8 、 Figure 10 and Figure 11 The first feeding device 4 includes a clamping component 41, a reset component 42 and a fixed plate 43. The clamping component 41 and the reset component 42 are respectively installed at both ends of the fixed plate 43. The end of the fixed plate 43 close to the reset component 42 is provided with an air source port 44. The clamping component 41 includes a clamping cylinder 411 and a first electromagnet 412 installed on the output rod of the clamping cylinder 411. The first electromagnet 412 is provided with a semicircular groove corresponding to the bottle wall of the packaging bottle 11. When the first electromagnet 412 is energized, the packaging bottle 11 can be adsorbed into the groove, thereby clamping and fixing the packaging bottle 11.

[0044] Among them, the reset assembly 42 includes a first limit plate 423, a second electromagnet 421 and a spring rod 422. The first limit plate 423 is installed on the upper part of the fixed plate 43. The number of the spring rods 422 is set to two and is installed between the first limit plate 423 and the second electromagnet 421. The second electromagnet 421 can move up and down on the spring rod 422 to adapt to the movement of the packaging bottle 11, so as to realize the packaging bottle 11 returning to its original position after inflation and sealing.

[0045] Among them, the second electromagnet 421 is also provided with a semicircular groove corresponding to the bottle wall of the packaging bottle 11, and the first limiting plate 423 is provided with an arc-shaped notch corresponding to the bottleneck of the packaging bottle 11. The second electromagnet 421 can adsorb the packaging bottle into the groove and limit it through the arc-shaped notch, thereby fixing the packaging bottle 11 and making it point vertically upward.

[0046] The first feeding device 4 can temporarily fix the packaging bottles 11 delivered by the second feeding device 8, and after the bottle caps are installed on the packaging bottles 11, they are transported to the sealing device 6 for inflation and sealing. Then, after the packaging bottles 11 are sealed, high-pressure gas is ejected through the gas source port 44 to blow the packaging bottles 11 into the blanking chute 12.

[0047] like Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown, the sealing device 6 includes an upper sealing component 61, a sealing component 62 and a lower sealing component 63 which are sequentially mounted on the frame 3 from top to bottom. The upper sealing component 61 includes a first cylinder 611 and an upper sealing mold 612 vertically mounted on the output rod of the first cylinder 611. The first cylinder 611 is used to drive the upper sealing mold 612, so that the upper sealing mold 61 seals the bottle 11 in the sealing component 62. The upper sealing mold 612 is provided with an air hole channel 6121 and an arc-shaped groove 6122 at the lower end port. The arc-shaped groove 6122 is used to be recessed into the structure at the bottle mouth of the bottle 11 to surround the bottle cap, thereby achieving the sealing of the bottle 11. The air hole channel 6121 allows gas to enter the arc-shaped groove 6122 from here and be filled into the bottle 11 during sealing.

[0048] The lower sealing assembly 63 includes a second cylinder 632 and a lower sealing mold 631 vertically mounted on the output rod of the second cylinder 632. The lower sealing mold 631 is driven by the second cylinder 632 to push the packaging bottle 11 on the second electromagnet 421 into the sealing assembly 62 for inflation and sealing.

[0049] The sealing assembly 62 is provided with an upper channel 627, a lower channel 629, an air inlet channel 624 and an air charging chamber 628. The upper channel 627, the lower channel 629 and the air inlet channel 624 are connected together through the air charging chamber 628. The upper sealing mold 612 is located in the upper channel and the diameters of the two correspond. The upper sealing mold 612 can move up and down in the upper channel 627. The air inlet channel 624 is connected to the gas source pipeline for providing gas, and a solenoid valve is provided on the gas source pipeline to fill the gas into the upper channel. The gas is then filled into the inflation chamber 628 and then into the packaging bottle 11. The lower channel 629 allows the bottle mouth of the packaging bottle 11 to extend into the inflation chamber, and the middle part of the packaging bottle 11 will block the lower end of the lower channel 629, thereby sealing the upper channel 627 and the lower channel 629 respectively through the upper sealing mold 612 and the packaging bottle 11. When the gas enters the inflation chamber 628 from the air inlet channel 624, it can be filled into the gas packaging bottle 11 along the inflation chamber 628, thereby realizing the filling of the gas.

[0050] The sealing assembly includes a main body block, an upper sealing gasket block 621, an upper sealing gasket 622, an intermediate sealing gasket 623, a sealing pressing block 625 and a lower sealing gasket 626. The intermediate sealing gasket 623 is installed inside the main body block. The intermediate sealing gasket 623 is used to seal the upper channel 627 of the main body block. The upper sealing gasket 622 is installed on the upper end face of the intermediate sealing gasket 623. The upper sealing gasket 622 is used to further seal the upper channel 627 of the main body block. The upper sealing gasket block 621 is installed on the upper end face of the upper sealing gasket 622. The upper sealing gasket block 621 is used to press the upper sealing gasket 622 and the intermediate sealing gasket 623. The lower sealing gasket 627 is installed at the port of the lower channel 629 of the main body block. The sealing pressing block 625 is installed on the upper end face of the lower sealing gasket 626. The sealing pressing block 625 is used to press the lower sealing gasket 626 so that it is stably installed inside the main body block.

[0051] Among them, gas is filled into the packaging bottle 11 in the inflation chamber 628. The inner circle of the sealing and pressing block 625 is larger than the diameter of the bottle mouth of the packaging bottle 11 and is also larger than the diameter of the upper sealing mold 612. The packaging bottle 11 is initially filled at the inner circle of the sealing and pressing block 625 (the upper sealing mold 612 has not moved down at this time). When the upper sealing mold 612 moves down to seal, since the upper sealing mold 612 isolates the bottle mouth of the packaging bottle 11 from the inflation chamber 628, the packaging bottle 11 can be further filled with gas through the air hole channel 6121 at this time, thereby ensuring that the packaging bottle 11 is full of gas and the product is normal.

[0052] like Figure 2 、 Figure 15 and Figure 16As shown, the collecting device 9 includes a blanking frame 91, a blanking component 92, a weighing component 93, a conveyor belt 95 and a rejection component 94. The weighing component 93 is located at the discharge end of the side of the blanking frame 2, the blanking component 92 is installed on the side of the weighing component 93, and the rejection component 94 is installed at the non-end of the conveyor belt 95. The conveyor belt 55 is provided with a defective product collection guide port 96 and a finished product collection guide port 97. The position of the defective product collection guide port 96 corresponds to the rejection component 94. The finished product collection guide port 97 is located at the end of the conveying direction of the conveyor belt 95. The weighing component 93 and the rejection component 94 are both controlled by a programmable controller.

[0053] The blanking chute 12 above the blanking frame 91 is installed at an angle. The blanking chute 12 is used to transport the packaging bottles 11 that have completed inflation and sealing and need to be weighed into the blanking frame 91. The bottom plate of the blanking frame 91 is installed at an angle facing the weighing component 93, so that the packaging bottles 11 in the blanking frame 91 can roll into the weighing component 93.

[0054] The blanking assembly 92 includes a blanking cylinder 921, a baffle 922 and a push plate 923. The baffle 922 and the push plate 923 are both installed on the output rod of the blanking cylinder 921. The baffle 922 is an "L"-shaped structure. Under the drive of the blanking cylinder 921, the baffle 922 can be blocked on the side wall of the blanking frame 91 or moved away to separate and close the wall panels of the blanking frame 91, and thereby control the rolling of the packaging bottles 11 in the blanking frame 91. Under the drive of the blanking cylinder 921, the push plate 923 can push the packaging bottles 11 on the weighing assembly 93 onto the conveyor belt 95 below.

[0055] The weighing component 93 is used to weigh the weight of the packaging bottle 11 and transmit the weighing information to the programmable controller. The conveyor belt 95 conveys the packaging bottle 11 in a specified direction, and the two sides of the conveyor belt 95 are provided with partitions for preventing the packaging bottle 11 from falling. The partitions are provided with notches at the corresponding positions of the defective product collection guide port 96 and the rejection component 94, so that the rejection component 94 can perform the rejection action and allow the packaging bottle 11 to fall into the defective product collection guide port 96.

[0056] The reject assembly 94 includes a reject cylinder and a third sensor (not shown). The third sensor is mounted on the conveyor belt 95 in front of the reject cylinder. The third sensor senses the bottles 11 and transmits a signal to the programmable controller. The controller then determines whether to allow the reject cylinder to reject the bottles based on the weight information. Collection bins for the bottles 11 are located below the defective product collection inlet 96 and the finished product collection inlet 97.

[0057] Specific working process: the cylinder vibrating plate 1 arranges the packaging bottles 11, and then transports them into the barrel 811 in a certain direction. The packaging bottles 11 entering the barrel 811 will fall downward and pass through the limitation of the gap of the second limiting plate 812, so that they fall vertically and enter the groove of the third electromagnet 823, and finally the packaging bottles 11 will fall onto the L-shaped plate 814.

[0058] When the second sensor on the L-shaped plate 814 senses the packaging bottle 11, it transmits a signal to the programmable controller, and then the programmable controller activates the third electromagnet 823 to firmly adsorb the packaging bottle 11 inside the groove.

[0059] Then the first feeding cylinder 821 is started, pushing the second feeding cylinder 822 and the third electromagnet 823 forward. After reaching the specified position, the second feeding cylinder 822 is started, so that it pushes the third electromagnet 823 onto the first electromagnet 412, and aligns the groove of the third electromagnet 823 with the groove of the first electromagnet 412. Then, the first electromagnet 412 is started, and the third electromagnet 823 is turned off, so that the first electromagnet 412 adsorbs the packaging bottle 11 into the internal groove, thereby completing the transportation of the packaging bottle 11 before capping.

[0060] After the conveying is completed, the first feeding cylinder 821 and the second feeding cylinder 822 will return to their original positions and prepare for the conveying of the next packaging bottle 11. After the first electromagnet 412 attracts the packaging bottle 11, the lifting cylinder 53 will be started, so that the output rod will slowly push the packaging bottle 11 on the first electromagnet 412 into the vertical channel of the positioning cylinder 702 (during this process, the first electromagnet will gradually be de-energized, allowing the packaging bottle to be pushed). Finally, the packaging bottle 11 will be pushed to the upper part of the positioning cylinder 702, and then the packaging bottle 11 will be clamped by the clamping claw 701 (at this time, the bottle mouth of the packaging bottle 11 is located in the through hole 525, and the bottle cap can be installed).

[0061] The bottle cap vibrating plate 2 is used to arrange the bottle caps so that they are neatly conveyed into the feeding channel 524 of the capping device 5. The bottle caps are then sensed by the first sensor, and the actions of the feeding cylinder 521 and the capping cylinder 511 are then controlled by the programmable controller so that the bottle caps are regularly pushed above the through holes 525 and pressed into the packaging bottles 11 clamped by the clamping claws 701, thereby completing the installation of the bottle caps.

[0062] After the bottle cap is installed, the lifting cylinder 53 contracts downward and the capping cylinder 511 continues to move downward, thereby pushing the packaging bottle 11 to the groove of the first electromagnet 412 below the positioning cylinder 701. Then the first electromagnet 412 is energized again to adsorb and clamp the packaging bottle 11. Then the clamping cylinder 1 is started to push the packaging bottle 11 into the semicircular groove of the second electromagnet 421 of the reset assembly 42. Then the first electromagnet 412 is de-energized and returns to its original position, while the second electromagnet 421 is energized to adsorb the packaging bottle 11 into the second electromagnet 421, thereby completing the transfer of the packaging bottle 11.

[0063] Next, the second cylinder 632 is activated, causing the lower sealing mold 631 to push the bottle 11 on the second electromagnet 421 upward into the sealing assembly 62 (at this time, the spring on the spring rod 422 is in a compressed state). Then the solenoid valve is opened, allowing high-pressure gas to enter the inflation chamber 628 from the air inlet channel 624 and fill the bottle 11 (there is a gap between the bottle cap installed on the bottle mouth, and the gas will be filled into the bottle through the gap). At the same time, the upper sealing mold 612, driven by the first cylinder 611, seals the bottle 11.

[0064] After the inflation and sealing are completed, the lower sealing mold 631 moves downward under the action of the second cylinder 632, and at this time the spring of the spring rod 422 is reset, causing the second electromagnet 421 and the packaging bottle 11 thereon to move downward. After returning to the initial position, the second electromagnet 421 is powered off, and at the same time, high-pressure gas is ejected from the gas source port 44, thereby blowing the packaging bottle 11 into the blanking chute 12, and then the packaging bottle 11 falls into the blanking frame 91 through the blanking chute 12.

[0065] After the packaging bottle 11 enters the blanking frame 91, the baffle 922 is pushed open by the blanking cylinder 921, so that the packaging bottle 11 rolls onto the weighing component 93, and then the baffle 922 moves back to block the opening of the blanking frame 91, and the weighing component 93 will weigh the falling packaging bottle 11 and transmit the weighing information to the programmable controller. When the weighing component 93 weighs the packaging bottle 11, the next packaging bottle 11 will continue to slide from the blanking chute 12 into the blanking frame 91. After weighing is completed, the blanking cylinder 921 continues to start, pushing the baffle 922 and the push plate 923 forward at the same time, so as to push the packaging bottle 11 on the weighing component 93 onto the conveyor belt 95, and at the same time, it will open the port of the blanking frame 91, so as to allow the next packaging bottle 11 to fall onto the weighing component 93, thereby controlling the opening and closing of the blanking frame 91, thereby controlling the blanking of the packaging bottle 11.

[0066] Bottles 11 that land on conveyor belt 95 are transported in a prescribed direction. They first pass the third sensor, which senses the bottle and transmits a signal to the programmable controller. The controller then uses this signal to determine whether the bottle 11 meets the weight requirements and controls the operation of the ejector cylinder. If the bottle 11 fails, the ejector cylinder pushes it into the defective product collection port 96, where it is collected. If the bottle passes the inspection, it is transported by conveyor belt 95 to the flat collection track 97, where it is collected, completing the sorting and collection of the bottles 11.

[0067] The present invention can realize the inflation and sealing of the packaging bottle, and the whole conveying and subsequent product collection can be completed by the machine, which can realize automatic production and improve production efficiency.

[0068] The above description is only a preferred embodiment of the present invention. The present invention is not limited to the above embodiment. There may be local minor structural changes during implementation. If various changes or modifications of the present invention do not depart from the spirit and scope of the present invention and fall within the scope of the claims of the present invention and equivalent technologies, the present invention is also intended to include these changes and modifications.
