DETAILED DESCRIPTION

[0066] The following describes the details and working principles of the embodiments and examples of the present invention in conjunction with the accompanying drawings. Figure 1 The X-axis direction is the longitudinal direction, also the front-to-back direction, and the Y-axis direction is the transverse direction, also the left-to-right direction.

[0067] This paper-plastic packaging and cartoning production line includes a paper-plastic packaging machine, a cartoning machine, and a transfer mechanism. The paper-plastic packaging machine includes a blister conveying mechanism, which includes a double-station transmission mold. The double-station transmission mold conveys longitudinally and passes through the blister station, feeding station 27, bottom card station 28, heat sealing station 30, and finished product output station 31 in sequence. The mold cavities on the double-station transmission mold are arranged in a horizontal line, and the mold cavities are provided in two rows. Traditional transmission molds use a single station, that is, the mold cavities are in a single row. The transmission mold is installed on a transmission chain, and the transmission chain drives the transmission mold to move. The use of the double-station transmission mold in the present invention not only improves product packaging efficiency, but also prepares for subsequent cartoning, speeds up cartoning, and significantly improves the production speed of the entire production line. The bubble shell enters the mold cavity of the double-station transmission mold from the bubble shell station, and is sent to the feeding station through the double-station transmission mold. The material is placed in the bubble shell, and then sent to the bottom card station. The bottom card is placed on the top of the bubble shell, and then sent to the heat sealing station. The bottom card and the bubble shell are sealed to form a product. Finally, the finished product is sent to the finished product output station. The bubble shell lowering, material placing, and bottom card placing can be done manually or by mechanical automation. The bubble shell lowering device, the material placing device, and the bottom card placing device are all existing technologies. The cartoning machine includes a stacking mechanism 32, which includes a first conveyor belt 41, a second conveyor belt 42, a suction plate 46, a turning part and a conveying component for driving the suction plate to turn over. The first conveyor belt 41 is arranged horizontally and connected with the finished product output station of the double-station transmission mold. The two are arranged vertically. The mold cavity of the double-station transmission mold is parallel to the first conveyor belt 41, and the second conveyor belt 42 is arranged parallel to the first conveyor belt. Along the conveying direction, the second conveyor belt is provided with a blanking station, a stacking station and a first pushing station in sequence. The first conveyor belt 41 only needs to have a blanking station and a stacking station. The suction plate 46 is arranged between the first conveyor belt and the second conveyor belt, that is, the suction plate is arranged at the blanking station. The surface of the suction plate is provided with a suction nozzle 45, which absorbs the finished product so that the finished product will not separate from the suction plate when it is turned over, in order to further improve stability. The suction plate 46 has a groove that matches the bubble shell of the finished product, that is, the finished product sinks into the groove of the suction plate, so that it is more stable when flipping. The flipping member can adopt a rotating shaft 52, and the rotation of the rotating shaft drives the suction plate 46 to flip, so that the finished product on the suction plate is flipped and placed on the second conveyor belt 42; the conveying component includes suction members 47 and 48 that rise and fall and a driving member that drives the suction member to move between the first conveyor belt and the second conveyor belt. The driving member and the power that drives the suction member to rise and fall can adopt a cylinder or a screw mechanism, etc. In order to make the longitudinal movement of the suction member more stable, the conveying component also includes a guide member, which includes a linear guide rail 56 and a slide 55 that slides with the linear guide rail. The slide is installed on the suction member, and the linear guide rail 56 is longitudinally installed on the frame 2, and the driving member drives the suction member to move longitudinally along the linear guide rail.The transfer mechanism includes a material picking member that rises and falls and a driving member 2 that drives the material picking member to move between the finished product output station 31 of the double-station transmission mold and the first conveyor belt 41. The material picking member is provided with two groups of material picking nozzles, and the two groups of material picking nozzles are arranged corresponding to the two rows of mold cavities on the double-station transmission mold. Similarly, the power for driving the material picking member to rise and fall and the driving member 2 can both use cylinders. In order to make the material picking member move smoothly, a guide rail can also be used. In order to facilitate the feeding of the transfer component and improve efficiency, the suction plate 46 and the starting end of the first conveyor belt 41 can be aligned with the double-station transmission mold. The mold cavity of the mold is aligned, so that the driving part 2 drives the material picking part to move forward and backward. When picking up the material, the driving part 2 drives the material picking part to move backward, and the material picking part moves down to suck the two groups of finished products of the finished product output station of the double-station transmission mold, which are the first group of products and the second group of products. Then the material picking part moves up, and the driving part 2 drives the material picking part to move forward, and the material picking part moves down again, and the two groups of material picking nozzles of the material picking part are respectively corresponding to the first conveyor belt 41 and the material suction plate 46. The two groups of material picking nozzles stop sucking, and the first group of products are placed on the first conveyor belt 41, and the second group of products are placed on On the suction plate 46, the suction nozzle 1 45 sucks the second group of finished products. In this embodiment, there are five suction plates, each of which is provided with a suction nozzle 1, and the five suction plates are also combined into one, that is, the suction plate is designed as an integrated whole; because the bubble shells of the finished products at the finished product output station are all set downward, the finished products placed on the first conveyor belt 41 and the suction plate 46 are all bubble shells downward and the bottom plate upward, and the rotation of the rotating shaft 52 drives the suction plate to flip toward the second conveyor belt 42, so that the second group of products is flipped 180 degrees and the bubble shell is set upward. The suction plate releases the second component and places it on the second conveyor belt 42, so that the products on the first conveyor belt 41 and the second conveyor belt 42 are facing opposite directions, and the two convey the finished products to the stacking station. The suction member moves down to adsorb the first component on the first conveyor belt 41, and then moves up. The driving member drives the suction member to move above the second conveyor belt 42, and the suction member moves down again to place the first component on the second conveyor belt. In this way, the first component and the second component are stacked together, and the second conveyor belt sends the stacked finished product to the first pushing station.

[0068] The first conveyor belt 41 and the second conveyor belt 42 are both provided with partitions 43, which divide the first conveyor belt and the second conveyor belt into a plurality of storage cavities. Each plate of material is placed in a storage cavity. The partitions 43 isolate the finished products on the conveyor belts, so that the finished products remain independent during the conveying process and avoid mixing together, thus preparing for the subsequent stacking operation. The rotating shaft 52 is installed with a limit plate 59, which has a notch 50. The frame is provided with a limit block 51, which is set in the notch of the limit plate. The rotation angle of the rotating shaft is within the angle limited by the notch. The rotation angle of the rotating shaft is controlled by the limit plate to improve the rotation accuracy. See the attached Figure 7The rotating shaft 52 rotates clockwise, and the upper end of the notch contacts the limit block. At this time, the suction plate is placed horizontally between the first conveyor belt 41 and the second conveyor belt 42. The rotating shaft 52 rotates counterclockwise, and the suction plate flips until the other end of the notch contacts the limit block 51. At this time, the suction plate flips to the top of the second conveyor belt 42. Baffles 44 are provided on both sides of the first conveyor belt and on both sides of the unloading station and the stacking station of the second conveyor belt. The baffles play a protective role and prevent the finished product from falling off the conveyor belt. To prevent the baffles from blocking the suction plate from flipping, the suction plate 46 is installed on the rotating shaft 52 through a connecting rod 54. The baffle of the suction station is provided with a notch 53 corresponding to the connecting rod. That is, when the suction plate flips, the connecting rod 54 is pressed into the notch 53, and the suction plate flips to the top of the second conveyor belt 42. The suction component includes a second suction nozzle 48 and a movable plate 47. The second suction nozzle is mounted on the movable plate, and the driving component drives the movable plate to move longitudinally. The first pushing station of the second conveyor belt 42 is provided with a pushing component and a stacking mechanism, which are respectively arranged on both sides of the second conveyor belt, and the stacking mechanism is arranged in front of the second conveyor belt. The pushing component includes a first push plate that moves longitudinally. The first push plate can be driven by a cylinder or a screw mechanism to move longitudinally. In order to avoid occupying position, the push plate is also connected to the cylinder 59 that drives it to rise and fall. After the first component and the second component are stacked, the first push plate 57 moves down, and then moves longitudinally into the storage cavity and pushes the stacked finished products to leave the storage cavity and enter the stacking mechanism 33. Then, the first push plate 57 moves up to leave the storage cavity, and finally retreats and resets. The stacking mechanism 33 stacks the stacked finished products.

[0069] The stacking mechanism 33 includes a first stacking rack 68 that is lifted up and down, a second stacking rack 69 and a second push plate that moves forward and backward. The lifting of the first stacking rack and the second stacking rack and the forward and backward movement of the second push plate can be driven by a cylinder or a screw mechanism; the first stacking rack 68 is open front and back, and the first stacking rack is provided with a plurality of vertically arranged partitions 77, and the partitions divide the first stacking rack 68 into a plurality of first stacking cavities, and the bottom of the first stacking cavity is provided with a supporting plate 64, and the middle of the supporting plate is provided with a longitudinal notch; the structure of the second stacking rack 69 is roughly the same as that of the first stacking rack 68, and the second stacking rack 69 is open front and back, and is provided with a plurality of vertically arranged partitions, and the partitions divide the second stacking rack 69 into a plurality of second stacking cavities, the number of the second stacking cavities is the same as that of the first stacking cavities and are arranged correspondingly front and back. In order to support the materials, a supporting plate 64 is also provided at the bottom of the second stacking cavity, but whether a notch is needed in the middle of the supporting plate is set according to demand. In this embodiment, the supporting plate 64 is opened The second push plate 67 is to push the finished product in the first stacking cavity into the second stacking cavity. Therefore, the second push plate has the notch 66 corresponding to the partition, and the support plate 64 has the notch corresponding to the push plate, so that the second push plate 67 can pass through the first stacking cavity and push the finished product into the second stacking cavity. According to requirements, three or four stacking racks can be provided. If there are three groups, the first two groups of stacking racks have the same structure as the first stacking rack, and the third group of stacking racks has the same structure as the second group of stacking racks. In this embodiment, only the first stacking rack 68 and the second stacking rack 69 are provided.The finished products are stacked for the second time by the second stacking rack 69, and the second stacking rack performs the same stacking operation as the first stacking rack, and so on and so forth until the finished products are stacked to the set height in the second stacking chamber, and finally the finished products that have been stacked are sent to the next process.

[0070] The stacking mechanism also includes a storage rack 72 that moves laterally and a third push plate 78 that moves forward and backward. The movement of the storage rack can be driven by a cylinder, a screw mechanism, a transmission belt, etc. The storage rack is open front and back, and the partition 79 on the storage rack divides the storage rack into several storage chambers. At the third pushing station, the storage chamber is arranged correspondingly to the front and back of the second stacking chamber; the third push plate 78 is arranged at the third pushing station, and the third pushing station is arranged below the second pushing station, that is, when the second stacking rack 69 moves down to the third pushing station, the finished product stacking is completed. At this time, the third push plate 78 pushes the finished products in the second stacking chamber into the storage chamber, so that the second stacking rack 69 is empty, and the finished product stacking operation continues after moving up and resetting. The frame is provided with a transversely arranged linear guide 74, and the linear guide is provided with a slide 73, and the slide is installed on the storage rack 72. At the discharge station, that is, on the side of the second stacking rack 69, a push plate 75 that moves back and forth is provided behind the storage rack. When the finished product enters the storage cavity, the storage rack 72 moves horizontally by one position, so that the first storage cavity moves to the discharge station, and the push plate 75 pushes out the finished product in the storage cavity at the discharge station. After pushing is completed, the push plate 75 moves in the opposite direction and resets, and the storage rack 72 continues to move one position, so that the next storage cavity moves to the discharge station, and the push plate pushes out the finished product in the storage cavity again, and so on and so forth. Until the finished products in all the storage cavities are sent out, the storage rack 72 moves in the opposite direction and resets along the linear guide to receive the finished products stacked by the second stacking rack.

[0073] See attached Figure 5The cartoning and packaging mechanism also includes a box opening device 35, which includes a forming platform 38, a box conveyor belt 36, and a box pushing plate 37. The box conveyor belt 36 and box pushing plate 37 are respectively arranged on both sides of the formed product platform 38. The box opening method is based on the existing technology, mainly using two guide plates 55 and a movable suction member 39. The two guide plates form a guide channel. The suction member 39 sucks one side of the package box. The suction member moves to cause the package box to enter the guide channel. The two guide plates 55 force the package box to open. Finally, the opened package box is placed on the forming platform. You can also refer to CN205770412U, a carton opening mechanism. In the accompanying drawings, the box conveyor belt 36 is consistent with the conveying direction of the double-station transmission mold, so the box pushing plate moves horizontally. The movement of the box pushing plate 37 can be driven by a cylinder. The box pushing plate pushes the package box on the forming platform 38 onto the box conveyor belt 36. The box conveyor belt then delivers the package box to the box removal station 95. In order to better connect the box body opening device and the box loading component, the box loading device also includes a box taking component, which includes a turntable 2 89 and a suction component 2 91. The turntable 2 is provided with a box taking station 95 and a box delivery station 90 in the circumferential direction. The box taking station is arranged above the box body conveyor belt. The box delivery station 90 is arranged opposite to the box suction station 92 on the left and right, that is, the suction nozzle 3 81 of the box suction station absorbs the packaging box of the box delivery station; the suction component 2 91 is provided with only a plurality of groups, and the suction component 2 is connected to a power component 96 that drives its radial movement. The power component can be a cylinder. A suction nozzle can be used, which is connected to an air source. The power member is evenly arranged along the circumference of the second turntable 89. When the second suction member rotates to the material-retrieving station 95, the power member drives the second suction member to move into the packaging box of the material-retrieving station, so that the second suction member 91 penetrates into the packaging box and absorbs the inner bottom surface of the packaging box. The second turntable 89 rotates, and the second suction member with the packaging box absorbed rotates to the box-feeding station 90, so that the bottom of the packaging box faces the suction station of the box-body transfer component. The suction nozzle 3 of the suction station absorbs the bottom surface of the packaging box, and then the second suction member stops sucking air, and the power member drives the second suction member to retract and reset. The present invention better connects the packaging box opening device with the box-loading component through the box-retrieving component, and adjusts the opening position of the packaging box to the state required for box loading.

[0074] The box loading and packaging mechanism also includes a packaging device, which includes a folding tongue component, a folding cover component, a folding tongue component and a conveying component; the folding tongue component is arranged above the box discharge station 93, and the folding tongue component includes a left lever and a right lever 98 that swing left and right. The power member that drives the left and right levers to swing can be a cylinder or a rotary motor, etc. In this embodiment, one end of the left lever and the right lever is hinged to the frame, and the left and right levers are connected to the cylinder that drives them to swing with the hinge as the center. The piston rod of the cylinder is extended, and the left lever and the right lever 98 swing toward the packaging box, so that the two small tongues on the packaging box are folded into the packaging box along the folding line. After folding is completed, the piston rod of the cylinder retracts, driving the left lever and the right lever 98 to swing in the opposite direction respectively. The reset left lever and right lever are arranged horizontally. The folding cover component is arranged in front of the box-out station 93, and the folding cover component includes a lower supporting plate 94 and an upper folding plate 97, with a carton channel between the two. The upper folding plate 97 is arranged to be tilted downward along the carton conveying direction, so that the upper cover of the packaging box entering the carton channel is gradually folded downward until the upper cover is completely covered on the box body; the folding tongue component includes a hook tongue component that moves up and down and a tongue pushing component that moves back and forth; the conveying component includes a conveyor belt 104 and a push plate 99 that pushes the box body of the box-out station onto the conveyor belt. In order to make way for the left and right levers, the push plate 99 is connected to the lifting cylinder that drives it to rise and fall. When pushing the box, the cylinder drives the push plate 99 to move downward, and then the push plate moves forward to push the box-out station 9 3 enters the conveyor belt 104, which is arranged horizontally, and the folding cover component and the folding tongue component 101 are arranged on one side of the conveyor belt, that is, the folding cover station and the folding tongue station are arranged in sequence along the conveying direction of the conveyor belt, and the lower supporting plate 94 is arranged between the box discharge station 93 and the conveyor belt 104. After the box discharge station completes the folding of the small tongue, the push plate 99 pushes the box toward the conveyor belt, and the lower supporting plate 94 holds the box, while the upper folding plate 97 folds the upturned upper cover of the box toward each other along the crease line, so that the upper cover is on the box body of the box, until the box completely enters the conveyor belt 104, and the conveyor belt delivers the box with the folded upper cover to the folding tongue station. In order to prevent the folded upper cover from rebounding, an upper baffle 100 is provided above the conveyor belt. The upper baffle is arranged before the upper cover folding station is transferred to the tongue folding station, that is, the upper baffle covers from the upper cover folding station to the tongue folding station. The distance between the upper baffle and the conveyor belt matches the height of the packaging box, thus preventing the upper cover from rebounding.The tongue assembly includes an upper base 111 and a plurality of tongue members 106. The tongue members are arranged transversely on the upper base 111, with gaps 109 between adjacent tongue members 106.

The tongue members 106 are positioned corresponding to the slots, and the front end of the tongue-pushing plate 110 corresponds to the gaps 109 between the tongue members. When pushing the tongue, the tongue-pushing plate 110 passes through the tongue members 106, pushing the tongue of the upper cover, causing it to fold inwardly. See attached. Figure 13 The cylinder is used to drive the hook tongue piece 106 to rise and fall and the tongue pushing piece to move back and forth. When the conveyor belt 104 delivers the packaging box to the large tongue folding station, the hook tongue piece moves down, and its tongue pressing step 107 presses the large tongue down, so that the large tongue is folded downward along the crease line, and then the hook tongue piece moves up, and its tongue lifting hook head 108 hooks the bottom of the large tongue, so that the upper cover is lifted up, and the large tongue is placed above the box body. At this time, the tongue pushing plate 110 of the tongue pushing piece passes through the adjacent hook tongue piece to push the large tongue to fold into the box body, the large tongue is separated from the tongue lifting hook head, and the hook tongue piece moves down again, and the tongue pressing step presses the large tongue into the box body. After completion, the hook tongue piece and the tongue pushing piece are reset. A waste rejection station is also provided along the conveying direction of the conveyor belt 104. The waste rejection station is provided with a weighing detector 102 and a box pushing plate 103 that moves back and forth. A finished product channel is provided in front of the weighing detector, a waste channel 106 is provided on one side of the weighing detector, and a waste rejection plate 105 that moves left and right is provided on the other side of the weighing detector. The box pushing plate and the waste rejection plate can also be driven by a cylinder. The power drive component and the weighing detector of the present invention are connected to the electrical controller, and the operation of each component is controlled by the electrical controller. The box that has been boxed and packaged is pushed from the conveyor belt 104 to the weighing detector 102 by the box pushing plate 103. The weighing detection machine weighs the box. If the weight of the box is within the set value range, the box pushing plate 103 continues to push the box into the finished product channel. On the contrary, if the weight of the box does not reach the set weight, it means that there are insufficient finished products in the box. The box pushing plate 103 retreats and resets, and the waste rejection plate 105 pushes the box into the waste channel 106. In this way, self-inspection is realized to ensure the product quality in the finished product area.

The slitting mechanism 25 is arranged at the slitting station of the transmission mold 2, and the plate separation mechanism 26 is arranged between the transmission mold 2 and the double-station transmission mold, and is connected with the two. The slitting mechanism 25 cuts the connected double-station bubble shells into two groups of unit bubble shells, and increases the spacing between the two groups of unit bubble shells after cutting through the plate separation mechanism 26, and sends them to the double-station transmission mold. The double-station bubble shell forming mechanism 23 is a prior art, that is, a bubble shell forming mechanism, but the existing bubble shell forming mechanism is to cut the continuous bubble shell into a single-station bubble shell, the present invention is to cut into a double-station bubble shell, the double-station bubble shell forming mechanism mainly includes a traction device, a heating device, a molding device, a longitudinal cutting device, a transverse cutting device and a sequence transfer device 24, that is, the traction device pulls the sheet forward and the sheet enters the molding device after being heated and softened by the heating device. The sheet is molded by the upper and lower molds of the molding device. The formed bubble shell is a continuous bubble shell. The continuous bubble shell is cut into several continuous bubble shells by the longitudinal cutting device and then enters the transverse cutting station. The transverse cutting device cuts the continuous bubble shell into a double-station bubble shell, that is, two bubble shells are connected together. When transversely cutting, The bubble shell needs to be moved forward to the position of two bubble shells for cross-cutting operation. The traction device is used to pull the double-station bubble shell from the sheet to the double-station bubble shell. At this time, the laterally adjacent double-station bubble shells are fitted together, and the lateral spacing between adjacent bubble shells needs to be increased through the sequence transfer device 24, and the bubble shell is sent to the transmission mold 2. The slitting mechanism 25 cuts the double-station bubble shell on the transmission mold 2 and cuts the double-station bubble shell into single-station bubble shells. At the same time, the two groups of single-station bubble shells are still on a transmission mold 2, so as to facilitate subsequent stacking operations. The sequence transfer device 24 is also a prior art in this field. Reference can be made to CN202107112U, a material conveying sequence transfer mechanism, and CN203283444U, a feeding mechanism for a paper-plastic packaging machine.

[0076] The slitting mechanism 25 includes a cross-cutting component and a power component that drives the cross-cutting component to move horizontally.

The first cutter and the second cutter are responsible for crosscutting operations in one direction respectively. When the first cutter 16 performs crosscutting operations, the driving assembly drives the first cutter to move downward and the second cutter 21 to move upward. At this time, the blade of the first cutter faces the bulb shell, and the blade of the second cutter faces away from the bulb shell. After the first cutter completes cutting, the mounting seat 11 returns and the second cutter 21 performs crosscutting. At this time, the first cutter 16 moves upward and the second cutter moves downward, and the blade of the second cutter faces the bulb shell. In this way, the first cutter and the second cutter are used alternately, which saves reset time and is thus more efficient. The driving assembly can use a cylinder or a screw mechanism to drive the first cutter and the second cutter to move up and down. Figure 3In this embodiment, the driving assembly includes a movable plate 12 and a driving member for driving the movable plate to move horizontally.

At this time, the second cutter 21 performs cross-cutting. Conversely, when the first cutter is used, the driving member drives the movable plate 12 to move to the right along the track 17, the second knife seat moves up, and the first knife seat moves down. The driving assembly of the present invention can simultaneously drive the first cutter and the second cutter to perform opposite actions, the structure is more compact, and the equipment cost is lower. When the double-station bulb is cut, in order to prevent the bulb from moving, the cutting mechanism also includes a pressing component, which includes a pressing plate 9 and a spring. The pressing plate is provided with a guide column 8, which is vertically arranged. The upper end of the guide column passes through the guide hole on the crossbeam 3, and an anti-slip block is installed on the top of the upper end of the guide column; the spring is arranged between the pressing plate 9 and the crossbeam 3, and the crossbeam is connected to a power source that drives it to move up and down. The power source can be a cylinder, and the cylinder is mounted on the frame. The spring 6 plays a buffering role to avoid a hard collision between the pressing plate and the mold below the bulb; a through groove 22 is provided on the pressing plate, and the first cutter and the second cutter are inserted into the through groove, that is, the cutter is just hidden in the through groove, so that the blade does not leak out, thereby improving safety in use. During cross-cutting, the cylinder 1 drives the crossbeam 3 to move downward, and the pressure plate 9 under the crossbeam first contacts the bulb, and the crossbeam continues to move downward until the cutter reaches the cross-cutting station. At this time, the pressure plate 9 presses the bulb, and the spring 6 is compressed. The guide column 8 passes through and moves upward along the guide hole. The power component drives the slide to move horizontally along the linear guide rail, and the cutter cross-cuts the bulb.

[0077] See attached Figure 4 and 14The plate separation mechanism includes a plate separation mold, a linear guide rail 2 40, a slide 29, a power piece and a shell feeding component.

The power piece drives the front plate and the rear plate to move toward or in the opposite direction along the linear guide rail 2. The power piece can use two cylinders to drive the front plate and the rear plate respectively. After the front plate and the rear plate move toward each other, the distance between the two is the same as the mold cavity distance on the transmission mold 2. The front plate and the rear plate After reverse movement, the distance between the two is the same as the distance between the mold cavities on the double-station transmission mold; the shell feeding component includes a front suction member 115 and a rear suction member 113 that can be lifted up and down, and a second driving member that drives the front and rear suction members to move forward and backward. The lifting of the front and rear suction members can be driven by a cylinder. The front suction member is provided with two rows of front suction nozzles 114, and the distance between the two rows of front suction nozzles matches the distance between the mold cavities on the double-station transmission mold. The rear suction member is provided with two rows of rear suction nozzles 112, and the distance between the two rows of rear suction nozzles matches the distance between the mold cavities on the transmission mold 2. The front suction member 115 and the rear suction member 113 are both mounted on a movable plate, and the second driving member drives the movable plate to move forward and backward. After the double-station bulb shells on the transmission mold 2 are cut into single-station bulb shells, the two groups of bulb shells adjacent in the longitudinal direction are tightly attached. It is necessary to increase the longitudinal distance between the bulb shells through a plate separation mechanism and send them to the double-station transmission mold. The driving member 2 drives the movable plate to move toward the transmission mold 2 until the rear suction member 113 is placed on the discharge station at the front end of the transmission mold 2, and the front suction member 115 is placed above the sub-plate mold. The front and rear suction members move down, and the rear suction member absorbs the two groups of bubble shells cut on the transmission mold 2, and the front suction member absorbs the two groups of bubble shells with larger spacing on the sub-plate mold, while the front and rear suction members move up, and the driving member 2 drives the movable plate to move forward until the rear suction member moves above the sub-plate mold, and the front suction member moves above the double-station transmission mold. After the bubble shell on the sub-plate mold is taken away, The power component drives the front plate 51 and the rear plate 50 of the plate separation mold to move toward each other, and the distance between the two is reduced and consistent with the mold cavity spacing on the transmission mold 2. The front and rear suction members move down again, and the rear suction plate 113 and the front suction plate 115 place the bubble shell on the plate separation mold and the double-station transmission mold respectively. Then the front and rear suction members move up again and reset, and the power component drives the front plate 51 and the rear plate 50 to move in the opposite direction, expanding the distance between the two. At this time, the distance between the two is consistent with the mold cavity spacing on the double-station transmission mold, so that the bubble shell is separated and the separated bubble shell is sent to the double-station transmission mold.

[0078] See attached Figure 1The paper-plastic packaging and cartoning production line is a combination of two paper-plastic packaging machines and two cartoning machines. The carton conveyor belt is shared. Therefore, a box-taking platform and a robot or push plate that delivers the cartons on the carton conveyor belt to the material-taking platform are required from the carton conveyor belt to the carton-taking station. The box-taking platform is set at the carton-taking station. After the paper-plastic packaging machine of this production line processes the sheet into double-station bubble shells, it is sent to the transmission mold 2. The double-station bubble shells are cut into two groups of unit bubble shells by the slitting mechanism, and the longitudinal spacing of the two groups of unit bubble shells is increased by the plate separation mechanism, and sent to the bubble shell station of the double-station transmission mold. Then the double-station transmission mold sends the two groups of bubble shells to the unloading station, the bottom card placing station, and the sealing station. Finally, the two groups of bubble shells are sealed with the two groups of bottom cards to form two groups of finished products, namely the first group of products and the second group of products. The finished products are sent to the finished product output station, and the transfer mechanism sends the two groups of finished products to the stacking mechanism. The stacking mechanism stacks the two groups of finished products into one group and pushes them to the stacking mechanism. The finished products are stacked to the boxing height by the stacking mechanism, and the push plate pushes the stacked finished products into the material conversion bin The packaging box is opened by the carton body opening device and sent to the box taking station. The box taking component of the carton loading device absorbs the packaging box from the box taking station and sends it to the box suction station.
