Description

Technical Field

[0001] The invention relates to the technical field of functional solvent packaging and processing, in particular to an inflation and plugging device for binary packaging. Background Art

[0002] Binary packaging is a multi-protection packaging system consisting of a valve, a discharge port, an aluminum can or an iron can. The agent and the propellant are packaged separately in their own containers, which reduces the complexity of the formula, does not release the propellant during use, and reduces the impact on safety and the environment.

[0003] In the Chinese patent application with application number: 201711455011.9, after the two-component package is filled with the paste product, the valve is sealed, the propellant is filled, the seal is filled and the plug is added, and the promoter is installed on the valve, and the promoter can be pressed to extrude the product. The filled product is generally a paste, such as paste food, anti-bite agent, silicone glue, STPE hybrid glue, polyurethane sealant, etc.

[0004] After completing the valve sealing process of the binary package, it is necessary to fill the accurately measured propellant into the lower cavity of the binary package, and then knock the plug into the bottom hole of the binary package. Through interference fit, the compressed gas is sealed to ensure that there is no gas leakage during transportation and storage.

[0005] At present, there is no similar equipment in China that can complete the processing of inflatable filling plugs. Summary of the invention

[0006] The purpose of the present invention is to provide an inflation and plugging device for a binary package in view of the above-mentioned problems, including a fixing device and an extrusion device. The fixing device is used to fix the binary package. A first driving component is provided inside the fixing device. Under the action of the first driving component, the binary package can be driven to move, so as to switch the binary package between a locked state and an unlocked state. When the binary package is in a locked state, the binary package cannot be removed from the fixing device; when the binary package is in an unlocked state, the binary package can be removed from the fixing device. Such a design is to avoid the binary package from falling off during the operation of the device. The extrusion device is used to assemble the plug onto the binary package, and the plug after plugging should have an interference fit with the agent hole.

[0007] Furthermore, the fixing device and the extrusion device are located on the same straight line, and the fixing device includes a first bracket arranged on the frame, a first driving component is fixed on the first bracket, an output end of the first driving component is connected to a fixing element, and the fixing element includes a mounting groove, and the mounting groove is used to install the binary package. The binary package is cylindrical, so the mounting groove is a cylindrical groove, and the bottom end of the binary package can be inserted into the mounting groove. The bottom of the binary package is recessed toward the propellant storage area. A protrusion matching the recess at the bottom of the binary package is provided in the mounting groove, and a first sealing ring is provided on the protrusion. The first sealing ring can increase the friction between the mounting groove and the binary package, and the binary package can be installed on the fixing element in combination with the inner wall of the mounting groove. The fixing device also includes a side bracket located on the frame, at least two side brackets are provided, and they are distributed up and down. The side bracket is provided with a circular groove matched with the binary package. When the binary package is against the circular groove of the side bracket, the agent storage area of ​​the binary package faces downward, and the bottom of the binary package can just enter the installation groove. The frame is also provided with an abutment block. When the binary package is installed in the installation groove, the binary package is in a non-locked state and the binary package can be removed from the installation groove; when the first driving component starts to drive the binary package downward through the fixed element, the top of the binary package contacts the abutment block, and the first driving component stops. At this time, the binary package is in a locked state, and the binary package cannot move or be removed. This state is the state when the plug is added, which can prevent the binary package from shaking when the plug is added. Since the binary package will contact the abutment block, in order to avoid the deformation of the binary package during the abutment process caused by the abutment block being too hard, the abutment block is preferably made of a soft material, such as rubber, and the abutment block is a cylindrical rubber pad.

[0008] Furthermore, the fixing element is provided with a first plug hole, which penetrates vertically. When the two-component package is installed on the fixing element, the first plug hole is directly opposite to the agent-passing hole.

[0009] Further, the extrusion device includes a second bracket arranged on the frame, and a second driving component is arranged on the second bracket, and the second driving component is connected to a striker, and the second driving component can insert the plug into the through-hole through the striker. In order to improve the efficiency of the plug being inserted into the through-hole, a two-stage driving component is arranged on the second bracket, and the secondary driving component has a stronger extrusion force than the primary driving component, which can greatly improve the insertion efficiency. Specifically, a second driving component is arranged on the second bracket, and the output end of the second driving component is connected to a third driving component, and the output end of the third driving component is connected to a striker, and the plug can be inserted into the through-hole through the striker. Due to the long length of the striker, if the striker is offset in the process of pushing the plug, it is very likely to cause the striker to break. In order to avoid this technical problem, during the design, the first bracket is appropriately enlarged, and a through hole is opened on the first bracket. The size of the through hole is the same as the diameter of the striker, and the striker and the through hole are transitionally matched. The striker can slide up and down in the through hole. Under the action of the through hole, it can ensure that the striker always remains vertically downward to avoid breaking due to the offset of the striker.

[0010] Furthermore, the upper opening of the first plug hole is large, and the lower opening is small. The upper opening size is similar to the diameter of the plug in the initial state, and the lower opening size is similar to the diameter of the agent hole. In the process of the striker pushing the plug, the plug is squeezed by the first plug hole and gradually becomes smaller. When it is squeezed to a size similar to the agent hole (slightly smaller than the agent hole), the plug enters the agent hole, and the plug is stretched open by its own elastic force, and is in close contact with the agent hole to achieve sealing of the agent hole. The approximation here refers to the same diameter, or the diameter difference is within 1mm.

[0011] Furthermore, a transition section is provided at the lower end of the striker, and the diameter of the transition section gradually decreases. A terminal end is also provided at the lower end of the transition section, and the diameters of the terminal ends are consistent at various positions. The transition section of the striker matches the first plug hole. When the striker moves downward, the transition section of the striker will contact the first plug hole, and the striker cannot continue to move downward. At this time, the terminal end of the striker enters the agent hole, and the diameter of the terminal end is smaller than the diameter of the agent hole. Therefore, the entry of the terminal end will not cause the agent hole of the binary package to be enlarged. At the same time, in this state, the plug is still in the agent hole, which prevents the striker from moving excessively and causing the plug to be pushed into the propellant storage area.

[0012] Furthermore, in the prior art, there are some two-component packages whose bottom drug-passing holes are hollow cylindrical. This hole design makes the processing of such two-component packages more complicated. There are also some two-component packages in the prior art, whose bottom drug-passing holes are punched out, which are more convenient to process. The edges of the drug-passing holes are petal-shaped and have some sharp corners. These sharp corners can prevent the plug from being pulled out after the plug is inserted into the drug-passing hole, because when the plug is pulled out, these sharp corners will jam the plug, which helps to prevent the plug from falling off.

[0013] Furthermore, a two-component packaging inflation and plugging device also includes a positioning device, which is mainly used to position the fixing device. This positioning is mainly to position the initial state of the fixing device so that the fixing device is located at a specified position. The positioning device includes a third bracket, on which a fourth driving component is provided. The output end of the fourth driving component is connected to a limit baffle, which is mainly used to limit the initial position of the fixing element to facilitate control by the first driving component. Furthermore, a second plug hole is provided on the limit baffle, and the second plug hole is used to place a plug. Generally, the positioning device is used together with the cutting device, which includes a knife holder and a blade. The knife holder is fixed on the third bracket, and the blade is located on the upper side of the limit baffle. A rubber strip is prepared, and one end of the rubber strip is inserted into the second plug hole. The rubber strip cannot extend out of the second plug hole. When the fourth driving component is started, the limit baffle drives the rubber strip to move toward the fixed element. On the way, the rubber strip contacts the blade and is cut into a plug. When the fourth driving component drives the limit baffle to the top of the fixed element, and the second plug hole is just opposite to the first plug hole, the cut plug falls into the first plug hole under the action of gravity. The fourth driving component starts to drive the limit baffle to reset, and at the same time, one end of the rubber strip is inserted into the second plug hole again, and the positioning device returns to the initial position. At this time, the fixing device and the extrusion device are started to execute the process of inserting the plug into the agent hole.

[0014] Furthermore, in actual production, binary packages have a variety of different sizes. Different binary packages have different bottom ends, that is, different sizes of applicable installation slots; even different binary packages have different sizes of drug holes, and different sizes of plugs are inserted. In order to enhance the applicability of the device to different binary packages, the fixing element is designed to be detachable and replaceable. Specifically, the fixing element includes a first fixing element, a second fixing element, and a third fixing element. The first fixing element is used to connect with the first driving component to drive the entire fixing element to move. The first fixing element is connected to the second fixing element. A first mounting hole is provided on the second fixing element, which runs through from top to bottom. A replaceable first extrusion element is installed in the first mounting hole. The first plug hole is provided in the first extrusion element. First extrusion elements of different models have first plug holes of different sizes inside. The first extrusion element is connected with the second fixing element by interference fit to ensure that the first extrusion element is sufficiently firm after installation. The first extrusion element is provided with a first annular groove, which is used to install the second sealing ring. The first extrusion element with the second sealing ring is connected to the second extrusion element. The second extrusion element is provided with a second mounting hole running through from top to bottom. The second mounting hole is sleeved on the outer side of the first extrusion element. The second extrusion element is fixed to the first extrusion element by the friction between the second mounting hole and the second sealing ring. Further, in order to make the connection between the first extrusion element and the second extrusion element relatively firm, two first annular grooves are provided on the first extrusion element. Accordingly, installing two second sealing rings can increase the maximum friction between the first extrusion element and the second extrusion element. The second extrusion element is in a stepped shape, the upper part of the second extrusion element is smaller, and the lower part is larger. Correspondingly, a stepped hole is also provided in the third fixing member to match the second extrusion, the upper part of the stepped hole is smaller, and the lower part is larger. The third fixing member can be fixed to the second fixing member through the first extrusion element and the second extrusion element. The mounting groove is provided on the third fixing member, and the first extrusion element and the second extrusion element are connected by friction, so that the third fixing member can be easily replaced. Different third fixing members have mounting grooves of different sizes, and accordingly, different binary packages can be matched. Further, an annular groove is provided on the second extrusion element, and the first sealing ring is fixed on the annular groove.

[0015] Furthermore, the above-mentioned fixing element can be replaced, and correspondingly, the firing pin can also be replaced. The output end of the third driving component is connected to the fixer, and the fixer is connected to the firing pin. The fixer can install different types of firing pins, and the selection of the firing pin depends on the size of the plug.

[0016] Furthermore, the first drive component, the second drive component, the third drive component, and the fourth drive component all perform linear motion when working, so the first drive component, the second drive component, the third drive component, and the fourth drive component can select some mechanical structures commonly used in the mechanical field that can achieve linear motion, such as linear cylinders, linear motors, gear racks, crank sliders, screw sliders, etc. Specifically, the designer selects different drive components according to the different requirements of different positions. The first drive component selects TN cylinders, the second drive component selects MA-SU cylinders, the third drive component selects SDAS cylinders, and the fourth drive component selects TN cylinders.

[0017] Furthermore, the first extrusion element is provided with a second annular groove, which is similar in shape to the first annular groove but has a completely different function. The second annular groove is used to fill the propellant into the propellant storage area. Specifically, a channel is provided in the first extrusion element, and the channel is connected to the second annular groove. When the first extrusion element is installed, the first extrusion element is located in the second fixing member. The device can also have the function of filling the propellant. It is only necessary to open a filling hole connected to the second annular groove in the second fixing member, and then fill the second annular groove with propellant through the filling hole before inserting the plug into the through hole. The propellant reaches the bottom position of the binary package through the channel and enters the propellant storage area through the through hole. After the propellant is filled, the plug is inserted into the through hole through the fixing device and the extrusion device. In the above process, the propellant is filled and the plug is inserted through the first plug hole and the channel respectively, and the two are independent of each other. The filling of the filler will not affect the plugging of the plug into the first plug hole.

[0018] The beneficial effects of the present invention are as follows: the inflating and plugging device for binary packaging provided by the present invention can perform plugging operations on plugs of different sizes for binary packaging of different sizes, and the plugs after plugging are not easy to fall off, the applicability is strong, and the plugging effect is good; during the plugging process, the fixing device can keep the binary packaging stable and prevent the binary packaging from falling off the device; during the plugging process, the first extrusion element can prevent the striker from excessively moving, and prevent the device from excessively running due to a malfunction during the processing, thereby preventing defects on the binary packaging: for example, the agent hole is enlarged, or the plug is pushed into the propellant storage area; the positioning device is combined with the cutting device to realize automatic filling of the plug, thereby improving the processing efficiency; in addition to having the function of plugging the plug, the device can also fill the propellant, and is highly practical.

[0032] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be pointed out that the embodiments are only a detailed explanation of the present invention and should not be regarded as a limitation of the present invention. All features disclosed in the embodiments of the present invention, or all steps in the methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any way.

[0033] In order to better facilitate others to understand the inflating and plugging device for a dual package provided by the present invention, the structure of the dual package 40 is first introduced here, and then the structure of the dual package 40 is introduced. Figure 1, including a tank body 41, a discharge port 48 and a valve structure 47, wherein the valve structure 47 is located at the top of the tank body 41, and the tank body 41 is provided with a material storage area 42 and a propellant storage area 43. When the tank body 41 is upright (such as the attached Figure 1 The dosage storage area 42 is located above the propellant storage area 43, the valve structure 47 is used to connect the dosage storage area 42 and the discharge port 48, the dosage storage area 42 and the propellant storage area 43 are connected by a piston 49, and the bottom of the tank body 41 is also provided with a through hole 50; a plug 44 is embedded in the through hole 50, and preferably, the plug 44 is a rubber plug. The binary package 40 can also be other binary packages 40 (with a plug 44) disclosed in the "Chinese patent application with application number: 201711455011.9". The structure of the binary package 40 is not the content of the present invention. The present invention mainly requests to protect a device that can fix the plug 44 to the through hole 50 of the binary package 40, so the structure of some other binary packages 40 will not be described in detail.

[0034] Refer to the attached Figure 2 The present invention relates to an inflatable plugging device for a binary package, comprising a fixing device 10 and an extrusion device 30. The fixing device 10 is used to fix a binary package 40. A first driving component 12 is provided inside the fixing device 10. Under the action of the first driving component 12, the binary package 40 can be driven to move, so as to switch the binary package 40 between a locked state and an unlocked state. When the binary package 40 is in a locked state, the binary package 40 cannot be removed from the fixing device 10; when the binary package 40 is in an unlocked state, the binary package 40 can be removed from the fixing device 10. This design is to prevent the binary package 40 from falling off during the operation of the device. The extrusion device 30 is used to assemble the plug 44 onto the binary package 40. The plugged plug 44 should be interference fit with the agent hole 50.

[0035] Specifically, the fixing device 10 and the extrusion device 30 are located on the same straight line. The fixing device 10 includes a first bracket 11 arranged on the frame 60. The first driving component 12 is fixed on the first bracket 11. The output end of the first driving component 12 is connected to the fixing element 13. The fixing element 13 includes a mounting groove 14. The mounting groove 14 is used to install the binary package 40. In this embodiment, the binary package 40 is cylindrical, so the mounting groove 14 is a cylindrical groove. The bottom end of the binary package 40 can be inserted into the mounting groove 14. The bottom of the binary package 40 is recessed toward the propellant storage area 43. A protrusion is provided in the mounting groove 14 to match the recessed bottom of the binary package 40. A first sealing ring 15 is provided on the protrusion. The first sealing ring 15 can increase the friction between the mounting groove 14 and the binary package 40. Combined with the inner wall of the mounting groove 14, the binary package 40 can be installed on the fixing element 13. The fixing device 10 also includes a side bracket 61 located on the frame body 60. There are at least two side brackets 61 distributed up and down. The side bracket 61 is provided with a circular groove 62 that matches the binary package 40. When the binary package 40 is against the circular groove 62 of the side bracket 61, one side (top end) of the dosage storage area 42 of the binary package 40 faces downward. At this time, the bottom end of the binary package 40 can just enter the installation groove 14. The frame body 60 is also provided with an abutment block 63. When the binary package 40 is installed in the installation groove 14, the binary package 40 is in an unlocked state and can be removed from the installation groove 14; when the first driving component 12 starts to drive the binary package 40 to move downward through the fixing element 13, the top of the binary package 40 contacts the abutment block 63, and the first driving component 12 stops. At this time, the binary package 40 is in a locked state, and the binary package 40 cannot be moved or removed. This state is the state when the plug 44 is plugged, which can prevent the binary package 40 from shaking when plugging. Since the binary package 40 will contact the abutment block 63, in order to prevent the abutment block 63 from being too hard and causing the binary package 40 to deform during the abutment process, the abutment block 63 is preferably made of a soft material, such as rubber. In this embodiment, the abutment block 63 is a cylindrical rubber pad.

[0036] Preferably, see Attachment Figure 3 The fixing element 13 is provided with a first plug hole 16 , which penetrates from top to bottom. When the binary package 40 is installed on the fixing element 13 , the first plug hole 16 is directly opposite to the agent hole 50 .

[0037] Refer to the attached Figure 2The extrusion device 30 includes a second bracket 17 arranged on the frame 60, and a second driving component is arranged on the second bracket 17. The second driving component is connected to the striker, and the second driving component can insert the plug into the agent hole through the striker. In this embodiment, in order to improve the efficiency of plugging the plug into the agent hole, the second bracket 17 is provided with a two-stage driving component. The secondary driving component has a stronger extrusion force than the primary driving component, which can greatly improve the plugging efficiency. Specifically, the second bracket 17 is provided with a second driving component 18, and the output end of the second driving component 18 is connected to the third driving component 19, and the output end of the third driving component 19 is connected to the striker 21. The plug 44 can be plugged into the agent hole 50 through the striker 21. Since the striker 21 is long, if the striker 21 deviates in the process of pushing the plug 44, it is very likely to cause the striker 21 to break. In order to avoid this technical problem, during the design, the first bracket 11 is appropriately enlarged, and a through hole 22 is opened on the first bracket 11. The size of the through hole 22 is the same as the diameter of the striker 21. The striker 21 and the through hole 22 are transitionally matched, and the striker 21 can slide up and down in the through hole 22. Under the action of the through hole 22, it can ensure that the striker 21 always remains vertically downward to avoid breaking due to the deviation of the striker 21.

[0038] Preferably, see Attachment Figure 3 , the upper opening of the first plug hole 16 is large, and the lower opening is small. The upper opening size is similar to the diameter of the plug 44 in the initial state, and the lower opening size is similar to the diameter of the agent hole 50. In the process of the striker 21 pushing the plug 44, the plug 44 is squeezed by the first plug hole 16 and gradually becomes smaller. When it is squeezed to a size similar to the agent hole 50, the plug 44 enters the agent hole 50, and the plug 44 is stretched open by its own elastic force, and is in close contact with the agent hole 50 to achieve the sealing of the agent hole. The approximation here refers to the same diameter, or the diameter difference is within 1mm.

[0039] Preferably, see Attachment Figure 4 A transition section 23 is provided at the lower end of the striker 21, and the diameter of the transition section 23 gradually decreases. A terminal end 24 is also provided at the lower end of the transition section 23, and the diameters of the terminal end 24 are consistent at various positions. The transition section 23 of the striker 21 matches the first plug hole 16. When the striker 21 moves downward, the transition section 23 of the striker 21 will contact the first plug hole 16, and the striker 21 cannot continue to move downward. At this time, the terminal end 24 of the striker 21 partially enters the agent hole 50, and the diameter of the terminal end 24 is smaller than the diameter of the agent hole 50. Therefore, the entry of the terminal end 24 will not cause the agent hole 50 of the binary package to be enlarged. At the same time, in this state, the plug 44 is still in the agent hole 50, which prevents the striker 21 from excessively moving and causing the plug 44 to be pushed into the propellant storage area 43.

[0040] Preferably, see Attachment Figure 6 and attached Figure 7 In the prior art, there are some binary packages 40 whose bottom agent holes 50 are hollow cylindrical. This hole design makes the processing of such binary packages 40 more complicated. In the prior art, there are also some binary packages 40 whose bottom agent holes 50 are punched out, which are more convenient to process. The edges of the agent holes 50 are petal-shaped and have some sharp corners. These sharp corners can prevent the plug 44 from being pulled out after the plug 44 is inserted into the agent hole 50, because when the plug 44 is pulled out, these sharp corners will jam the plug 44, which helps to prevent the plug 44 from falling off.

[0041] A dual-packaging gas filling and plugging device, see attached Figure 2 , and also includes a positioning device 20. The positioning device 20 is mainly used to position the fixing device 10. This positioning is mainly to position the initial state of the fixing device 10 so that the fixing device is located at a specified position. The positioning device 20 includes a third bracket 25. The third bracket 25 is provided with a fourth driving component 26. The output end of the fourth driving component 26 is connected to a limiting baffle 27. The limiting baffle 27 is mainly used to limit the initial position of the fixing element 13 to facilitate the control of the first driving component 12. Furthermore, the limiting baffle 27 is provided with a second plug hole 28. The second plug hole 28 is used to place a plug 44. Generally, the positioning device 20 is used in conjunction with a cutting device. Please refer to the attached Figure 8 The cutting device includes a knife holder 31 and a blade 32. The knife holder 31 is fixed on the third bracket 25. The blade 32 is located on the upper side of the limit baffle 27. A rubber strip (not shown in the figure) is prepared, and one end of the rubber strip is inserted into the second plug hole 28. The rubber strip cannot extend out of the second plug hole 28. When the fourth driving component 26 is started, the limit baffle 27 drives the rubber strip to move toward the fixed element 13. On the way, the rubber strip contacts the blade 32 and is cut into a plug 44. When the fourth driving component 26 drives the limit baffle 27 to come above the fixed element 13, and the second plug hole 28 is just opposite to the first plug hole 16, the cut plug 44 falls into the first plug hole 16 under the action of gravity. The fourth driving component 26 starts to drive the limit baffle 27 to reset, and at the same time, one end of the rubber strip is inserted into the second plug hole 28 again, and the positioning device 20 returns to the initial position. At this time, the fixing device 10 and the squeezing device 30 are started to execute the process of inserting the plug 44 into the agent hole 50 .

[0042] Preferably, in the actual production process, the binary package 40 has a variety of different sizes. Different binary packages 40 have different bottom ends, that is, the applicable installation slots 14 have different sizes; even different binary packages 40 have different sizes of through holes 50 and different sizes of plugs 44. In order to enhance the applicability of the device to different binary packages 40, the fixing element 13 is designed to be detachable and replaceable. For details, refer to the attached Fig. 9 -Attached Fig.12 The fixing element 13 includes a first fixing member 70, a second fixing member 71, and a third fixing member 72. The first fixing member 70 is used to connect with the first driving component 12 to drive the entire fixing member 13 to move. The first fixing member 70 is connected to the second fixing member 71. The second fixing member 71 is provided with a first mounting hole 73 that runs through from top to bottom. A replaceable first extrusion element 74 is installed in the first mounting hole 73. The first plug hole 16 is provided in the first extrusion element 74. Different models of first extrusion elements 74 have first plug holes 16 of different sizes. The first extrusion element 74 is connected with the second fixing member 71 by interference fit to ensure that the first extrusion element 74 is sufficiently firm after installation. The first extrusion element is provided with a first annular groove 7 5. The first annular groove 75 is used to install the second sealing ring 76. The first extrusion element 74 with the second sealing ring 76 is connected to the second extrusion element 77. The second extrusion element 77 is provided with a second mounting hole 78 which runs through from top to bottom. The second mounting hole 78 is mounted on the outer side of the first extrusion element 74. The second extrusion element 77 is fixed to the first extrusion element 74 through the friction between the second mounting hole 78 and the second sealing ring 76. Furthermore, in order to make the connection between the first extrusion element 74 and the second extrusion element 77 relatively firm, two first annular grooves 75 are provided on the first extrusion element 74. Accordingly, installing two second sealing rings 76 can increase the maximum friction between the first extrusion element 74 and the second extrusion element 77. The second extrusion element 77 is stepped, the upper part of the second extrusion element 77 is smaller, and the lower part is larger (described in the direction when the device is in the upright state, the same below), and accordingly, the third fixing member 72 is also provided with a stepped hole 79 matched with the second extrusion 77, the upper part of the stepped hole 79 is smaller, and the lower part is larger, and the third fixing member 72 can be fixed to the second fixing member 71 through the first extrusion element 74 and the second extrusion element 77, the mounting groove 14 is provided on the third fixing member 72, and the first extrusion element 74 and the second extrusion element 77 are connected by friction, so that the third fixing member 72 can be easily replaced, and different third fixing members 72 have mounting grooves 14 of different sizes, and accordingly, different binary packages 40 can be matched. Further, the second extrusion element 77 is provided with an annular groove 80, and the first sealing ring 15 is fixed on the annular groove 80.

[0043] Preferably, the fixing element 13 can be replaced, and correspondingly, the striker 21 can also be replaced. The output end of the third driving component 19 is connected to the fixture 81, and the fixture 81 is connected to the striker 21. The fixture 81 can install different types of strikers 21, and the selection of the striker 21 depends on the size of the plug 44.

[0044] Preferably, the first drive component 12, the second drive component 18, the third drive component 19, and the fourth drive component 26 all perform linear motion when working, so the first drive component 12, the second drive component 18, the third drive component 19, and the fourth drive component 26 can use some commonly used mechanical structures in the mechanical field that can achieve linear motion, such as linear cylinders, linear motors, gear racks, crank sliders, screw sliders, etc. Specifically, in this embodiment, the designer selects different drive components according to the different needs of different positions. The first drive component 12 uses a TN cylinder (double-axis double-rod cylinder), the second drive component 18 uses a MA-SU cylinder, the third drive component 19 uses a SDAS cylinder (square cylinder), and the fourth drive component 26 uses a TN cylinder.

[0045] Preferably, see Attachment Fig.13 The first extrusion element 74 is provided with a second annular groove 82, which is similar in shape to the first annular groove 75 but has a completely different function. The second annular groove 82 is used to fill the propellant into the propellant storage area 43. Specifically, the first extrusion element 74 is provided with a channel 83, which is connected to the second annular groove 82. When the first extrusion element 74 is installed, the first extrusion element 74 is located in the second fixing member 71. The device can also have the function of filling the propellant. It is only necessary to open a filling hole connected to the second annular groove 82 in the second fixing member 71, and then fill the propellant into the second annular groove 82 through the filling hole before inserting the plug 44 into the through hole 50. The propellant reaches the bottom position of the binary package 40 through the channel 83, and enters the propellant storage area 43 through the through hole 50. After the propellant is filled, the plug 44 is inserted into the through hole 50 through the fixing device 10 and the extrusion device 30. In the above process, the propellant is filled and the plug 44 is inserted through the first plug hole 16 and the channel 83 respectively, which are independent of each other. The filling of the filler will not affect the insertion of the plug 44 into the first plug hole 16.

[0046] In order to facilitate others to understand the device of the present invention, the following is an explanation of the working state in combination with the device structure: the operator inserts the bottom end of the binary package 40 into the installation groove 14, the binary package 40 is in an inverted and unlocked state, the operator inserts one end of a rubber strip into the second plug hole 28, and controls the position of the rubber strip to prevent the rubber strip from extending out of the second plug hole 28; the fourth driving component 26 is started, and the limit baffle 27 drives the rubber strip to move toward the fixing element 13. On the way, the rubber strip contacts the blade 32 and is cut into plugs 44. At this time, the second fixing member 71 is located at the limit baffle. The stopper 27 is positioned below the second plug hole 28 to prevent the plug 44 from falling out of the second plug hole 28. The fourth driving component 26 continues to move until the second plug hole 28 is just opposite to the first plug hole 16. At this time, the plug 44 falls into the first plug hole 16 under the action of gravity. The fourth driving component 26 starts to drive the limit stopper 27 to reset. At the same time, one end of the rubber strip is inserted into the second plug hole 28 again to prepare for cutting the next plug 44 (if the equipment does not have a positioning device 20 and a cutting device, the cut plug 44 can be directly placed in the first plug hole 16 of the fixing element 13).

[0047] (If propellant filling is required, this step is performed to fill the second annular groove 82 with propellant through the filling hole, and the propellant reaches the bottom position of the dual package 40 through the channel 83 and enters the propellant storage area 43 through the propellant hole 50);

[0048] The first driving component 12 starts, and drives the binary package 40 to move downward through the fixing element 13. The top of the binary package 40 contacts the abutment block 63, and the first driving component 12 stops. At this time, the binary package 40 is in a locked state. The second driving component 18 and the third driving component 19 start, and drive the striker 21 to move downward. In the process of the striker 21 pushing the plug 44, the plug 44 is squeezed by the first plug hole 16 and gradually becomes smaller. When it is squeezed to a size similar to the through hole 50, the plug 44 enters the through hole 50. After entering, the plug 44 is stretched open by its own elastic force, and is in close contact with the through hole 50 to achieve the sealing of the through hole. (The plugging process of the plug 44 is not completed in one time. Generally, the plugging operation is completed after the striker 21 squeezes the plug 44 downward several times).

[0049] When the plug 44 is inserted, the first drive component 12 controls the fixing device 10 to return to the initial position, and the second drive component 18 and the third drive component 19 control the extrusion device 30 to return to the initial position. At this time, the binary package 40 is in the unlocked state again, and the operator removes the binary package 40 from the installation groove 14.

[0050] The above is only a specific implementation method of the invention, but the protection scope of the invention is not limited to it. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the invention. Therefore, the protection scope of the invention should be based on the protection scope defined in the claims.
