The force is uniform and the material distribution speed is controllable.

[0031] (4) The fully automatic milk carton gift box wrapping system of the present invention includes a carton material hopper feeding device. The layered carton material hopper can store multiple carton bodies at one time, providing sufficient material buffer for the production line. This reduces the frequency and time of production line stoppages caused by replenishing empty material hoppers, ensuring the smoothness of production. The receiving mechanism can extend into the lifting mechanism to pick up the carton, realizing a smooth transition of material from horizontal pushing to vertical conveying, reducing the risk of jamming and collision. The lifting mechanism, through the design of the lifting support rod, can stably support and transport the carton.

[0032] (5) The fully automatic milk carton gift box wrapping system and the carton transfer device of the present invention complete the carton transfer operation through automated equipment. By setting the carton alignment mechanism, the stacked carton bodies that become loose during the transfer process become a whole, which facilitates subsequent operations.

[0033] (6) The fully automatic milk carton gift box wrapping system and the carton linkage material picking device of the present invention integrate the three major functions of storage, picking and feeding into one device, avoiding the space occupation problem caused by the separate arrangement of independent material bins, picking machines and conveyor lines in traditional automation solutions. It is particularly suitable for production sites with limited factory space, realizing efficient utilization of limited space. Through the linkage drive and cam combination structure, the suction cup is driven to realize the composite movement of horizontal and vertical. The picking path is reasonable and the action is stable. It can quickly and accurately pick up the carton from the storage channel and transfer it to the next work station, significantly improving the production cycle and overall packaging efficiency.

[0034] (7) The fully automatic milk bag gift box wrapping system created by the present invention places the milk bag on the feeding device of the box. By setting the milk bag stacking device, the rhythm of the milk bag pad conveying device and the box conveying device is unified, so that the two conveying devices can smoothly place the milk bag on the box at the intersection point, thus ensuring the stability of the production line rhythm.

[0035] (8) The fully automatic milk carton gift box wrapping system of the present invention has a side leaf inserting device for the carton, which is symmetrically arranged on both sides of the conveying equipment. The side leaves of both sides can be inserted simultaneously during the conveying process without stopping or secondary positioning, which significantly improves the production cycle and the overall efficiency of the production line. The inserting rod adopts a connecting rod structure with the main rod and the auxiliary rod hinged together. It automatically folds in the arc section of the chain and unfolds in the straight section. The folded state reduces the turning space and avoids interference with the box body.

The milk bag gripping and transferring device 4 is configured to transfer the milk bag body that has entered the padded milk bag conveyor line to the main conveyor line of the system. Both the lower pad material well and the carton lower pad material well picking device 1 are located on the top of the box frame. The lower pad material well is fed by the overhead crane in the workshop. The carton lower pad material well picking device 1 is used to take out the stack of lower pad bodies in the lower pad material well and place them into the carton lower pad material sorting device 2. The carton lower pad material sorting device 2 is used to separate the stack of lower pad bodies one by one. The separated lower pad bodies are transported to the system conveying main line by the carton lower pad material grabbing and transfer device 3. The working methods of the carton upper pad material well picking device, the carton upper pad material distribution device, and the carton upper pad material gripping and transferring device are the same as those of the carton lower pad material well picking device 1, the carton lower pad material distribution device 2, and the carton lower pad material gripping and transferring device 3. The lower pad body first enters the system's main transmission line, the milk bag body is placed on the lower pad body, and the upper pad body is then placed on top of the milk bag body. The three combine and continue to be transmitted on the system's main transmission line. The sheet box hopper 52 is transported to the sheet box hopper 52 feeding device 5 by an overhead crane. The sheet box hopper 52 feeding device 5 is used to take the sheet box body out of the sheet box hopper 52 in stacks and transfer it to the sheet box transfer device 6. The sheet box transfer device 6 is located below the main conveyor line of the system. The sheet box transfer device 6 is used to transfer the sheet box body to the sheet box connecting rod picking device 7. The sheet box connecting rod picking device 7 is used to take out the sheet box body one by one and transport it to the sheet box inclined conveyor line 9. The milk bag stacking device 8 is located at the end of the system's main conveyor line. It is used to adjust the pace of the conveyed pad milk bags so that it is consistent with the pace of the carton incline conveyor line 9. Through the milk bag stacking device 8, the pad milk bags and the carton body intersect at the finished carton conveyor line, and the pad milk bags are placed on the carton. The sheet box folding mechanism and the sheet box glue application mechanism are installed on the box frame. The sheet box folding mechanism is used to fold the conveyed sheet boxes into square boxes, and the sheet box glue application mechanism is used to apply glue to the positions on the sheet boxes that need to be glued. The side blade driving device 10 is used to drive and compact the side blades at both ends of the box, and the upper and lower blade driving device is used to drive and compact the upper and lower blades at both ends of the box.

[0043] Preferred, such as Figures 15-17 As shown, the milk bag gripping and transfer device 4 includes a milk bag moving mechanism 41 and a milk bag gripping mechanism 42. The gripping integrated plate 422 of the milk bag gripping mechanism 42 is installed on the moving end of the milk bag moving mechanism 41 to realize the horizontal and vertical movement of the milk bag gripping mechanism 42. The milk bag gripping mechanism 42 is provided with a plurality of milk bag gripping components 421 to realize the simultaneous gripping operation of multiple milk bags.

[0044] Preferably, the milk bag moving mechanism 41 includes a milk bag lateral moving mechanism 411 and a milk bag vertical moving mechanism 412. The milk bag lateral moving mechanism 411 includes a milk bag lateral fixing frame 4111, a milk bag lateral moving motor 4112, a milk bag lateral moving seat 4113, and a milk bag lateral moving screw 4114. The milk bag lateral fixing frame 4111 is provided with a slide rail and the milk bag lateral moving motor 4112. The milk bag lateral moving seat 4113 is slidably connected to the slide rail by a slider, and a nut seat is provided on the milk bag lateral moving seat 4113. One end of the milk bag lateral moving screw 4114 is threadedly connected to the nut seat, and the other end is connected to the output end of the milk bag lateral moving motor 4112, thereby driving the movement of the milk bag lateral moving seat 4113. The milk bag vertical moving mechanism 412 includes a milk bag vertical fixing frame 4121, a milk bag vertical moving motor 4122, a milk bag vertical moving seat 4123, and a milk bag vertical moving screw 4124; the milk bag vertical fixing frame 4121 is installed on the milk bag horizontal moving seat 4113, the milk bag vertical moving motor 4122 is installed on the milk bag vertical fixing frame 4121, and the milk bag vertical moving seat 4123 is provided with two connecting arms, which pass through the milk bag horizontal moving seat 4113 and are connected to the gripping integrated plate 422 of the milk bag gripping mechanism 42; The vertical moving seat is equipped with a nut seat. One end of the milk bag vertical moving screw 4124 is threaded to the nut seat, and the other end is connected to the output end of the milk bag vertical moving motor 4122, thereby realizing the driving of the vertical movement of the milk bag gripping mechanism 42.

[0045] Preferably, the milk bag gripping mechanism 42 includes milk bag gripping components 421 and gripping integrated plate 422, with three milk bag gripping components 421 installed on the gripping integrated plate 422. By installing multiple independent gripping components side by side on the gripping integrated plate 422, multiple milk bags in a row can be gripped simultaneously at one time, significantly improving the efficiency of a single operation and perfectly matching the cycle time requirements of high-speed production lines. The number and layout of the gripping components can be flexibly configured on the gripping integrated plate 422 according to the product packaging form and the quantity requirements for each transfer, enabling the equipment to quickly adapt to different production orders and layouts. Preferably, the milk bag gripping assembly 421 includes a milk bag gripping cylinder 4211, a milk bag gripping top plate 4212, a first clamping plate 4213, a second clamping plate 4214, a third clamping plate 4215, a fourth clamping plate 4216, and a hinge plate 4217. The milk bag gripping top plate is mounted to the gripping integrated plate 422 via a connecting frame. The milk bag gripping top plate 4212 is rectangular. The first clamping plate 4213, the second clamping plate 4214, the third clamping plate 4215, and the fourth clamping plate 4216 are respectively connected to the four sides of the milk bag gripping top plate 4212 via rotating shafts, enabling the clamping plates to rotate relative to the milk bag gripping top plate 4212. The milk bag gripping cylinder 4211 is mounted on the top of the milk bag gripping top plate 4212, and the milk bag... The output end of the gripping cylinder 4211 passes through the milk bag gripping top plate 4212 and is connected to the hinge plate 4217. The four sides of the hinge plate 4217 are respectively hinged to the inner sides of the first clamping plate 4213, the second clamping plate 4214, the third clamping plate 4215, and the fourth clamping plate 4216 through a hinge arm. The milk bag gripping cylinder 4211 drives the hinge plate 4217 to move up and down, which can realize the simultaneous opening and closing of the first clamping plate 4213, the second clamping plate 4214, the third clamping plate 4215, and the fourth clamping plate 4216. This linkage mechanism ensures that the four clamping plates contact or leave the milk bag at the same time, gripping smoothly without squeezing the product off-center, forming a uniform centripetal clamping force on the milk bag, and avoiding excessive local pressure that could cause packaging deformation or damage.

[0046] Preferably, the gripping integrated plate 422 is provided with two guide rods, respectively located on both sides of the milk bag gripping cylinder 4211. One end of the guide rod is connected to the gripping integrated plate 422, and the other end passes through the milk bag gripping top plate 4212 and connects to the hinge plate 4217, thereby achieving linear guidance of the hinge plate 4217. This effectively prevents the hinge plate 4217 from rotating or jamming during movement, ensures vertical transmission of driving force, makes the opening and closing action of the clamping plate smoother and more reliable, and extends the service life of the cylinder and hinge components.

[0047] Preferably, each of the clamping plates 4213, 4214, 4215, and 4216 is provided with threaded holes. By setting a spacer 4218 and threadedly connecting it to the threaded holes, the volume of each clamping plate 4213, 4214, 4215, and 4216 can be changed. This allows it to adapt to milk bag products of different sizes and quantities, enhancing the versatility of the equipment.

[0048] Working principle of the milk bag gripping and transfer device: The horizontal movement motor drives the lead screw to move the entire vertical movement mechanism (including the gripping mechanism) directly above the milk bag. Then, the vertical movement motor drives the lead screw to lower the gripping mechanism to the preset gripping height. The milk bag gripping cylinder 4211 on each gripping component actuates, pushing the internal hinge plate 4217 downwards. The hinge plate 4217, through four hinge arms, synchronously pulls the four clamping plates inwards to close, thus firmly gripping the milk bag below. After gripping, the vertical movement motor reverses, raising the gripped milk bag to a safe height.

[0069] Working principle: The lower pad body is stacked in the lower pad distribution well 21. There are gaps between the two lower pads stacked together. As the distribution wheel body 2321 rotates, the thin end of the spiral blade 2322 enters between the two lower pad bodies through rotation. Continued rotation can open up the two adjacent lower pad bodies and finally complete the separation. The bottom lower pad body falls down onto the conveyor belt. The conveyor belt moves forward in a step-by-step manner, dropping one pad at a time. Once the pad bodies are arranged on the conveyor belt, the horizontal transfer motor 3221 for the carton pads starts.

At the same time, the piece box body contacts the receiving baffle 558 during the pushing process to complete the alignment of the piece box body and make it neat. Then the piece box receiving rod 563 of the piece box receiving mechanism 56 retracts and the piece box body falls between the two lifting support rods 554. Then the lower pusher mechanism 54 operates to push the bottommost piece box body to the piece box transfer device 6.

Furthermore, the material storage mechanism 71 of this sheet box has no complex power components. It uses the weight of the sheet box to drop and store materials, and uses the lower bent adjustment plate for physical limiting and support. The structure is simple, the failure rate is low, and maintenance is convenient.

[0089] Preferably, the sheet box linkage material handling mechanism 72 includes a linkage material handling base plate 721, a material handling horizontal moving box 722, a material handling vertical moving frame 723, a linkage material handling drive assembly 724, and a linkage material handling driven assembly 725; The material picking horizontal moving box 722 is slidably connected to the connecting rod picking base plate 721 via a slider rail, so that the material picking horizontal moving box 722 can move laterally relative to the connecting rod picking base plate. The vertical material picking frame 723 is slidably connected to both sides of the horizontal material picking box 722 via a slider rail, so that the vertical material picking frame 723 can move vertically relative to the horizontal material picking box 722. Both the connecting rod material picking drive assembly 724 and the connecting rod material picking driven assembly 725 are installed on the material picking horizontal moving box 722, and the two are connected by a synchronous belt. The connecting rod material picking drive assembly 724 is used to drive the material picking horizontal moving box 722 to move, and the connecting rod material picking driven assembly 725 is used to drive the material picking vertical moving frame 723 to move vertically. The entire material handling action (lateral movement and vertical lifting) is driven by only one drive motor through a clever cam, linkage, and synchronous belt system. This mechanical linkage ensures strict synchronization and precise coordination of the suction cup lifting and lateral movement in time and space, resulting in reliable motion trajectory and high repeatability. Preferably, the connecting rod material picking drive assembly 724 includes a connecting rod material picking drive motor 7241, a connecting rod material picking drive rod 7242, a connecting rod material picking drive wheel 7243, a connecting rod material picking drive cam 7244, and a connecting rod material picking drive arm 7245; The connecting rod material picking drive motor 7241 is installed on the material picking lateral moving box 722. One end of the connecting rod material picking drive rod 7242 is connected to the output end of the connecting rod material picking drive motor 7241, and the other end passes through the material picking lateral moving box 722 and is connected to the connecting rod material picking drive cam 7244. The connecting rod material picking drive rod 7242 is provided with a connecting rod material picking drive wheel 7243. The connecting rod picking base plate 721 is provided with a connecting seat, and the connecting rod picking drive cam 7244 is hinged to the connecting seat through the connecting rod picking drive arm 7245.

[0090] Preferably, the connecting rod material-picking follower assembly 725 includes a connecting rod material-picking follower rod 7251, a connecting rod material-picking follower wheel 7252, a connecting rod material-picking follower cam 7253, and a connecting rod material-picking follower arm 7254; The connecting rod driven rod 7251 is installed to the material picking transverse moving box 722. Both ends of the connecting rod driven rod 7251 pass through the material picking transverse moving box 722 and are respectively connected to a connecting rod driven cam 7253. The two linkage-driven cams are respectively hinged to the connecting seat of the vertical moving frame 723 via the linkage-driven arm 7254; The connecting rod picking driven rod 7251 is provided with a connecting rod picking driven wheel 7252, and the connecting rod picking driven wheel 7252 and the connecting rod picking drive wheel 7243 are connected by a synchronous belt.

[0091] Preferably, the vertical moving frame 723 includes a vertical moving top plate 7231 and vertical moving columns 7232. A vertical moving column 7232 is respectively provided at the four corners of the lower surface of the vertical moving top plate. Each vertical moving column 7232 is slidably connected to both sides of the horizontal moving box 722 via a slider rail. Several suction cups are provided on the upper surface of the vertical moving top plate 7231. The vertical moving frame 723 for picking up materials is connected to the moving box via slider rails at the four corners. During movement, it can effectively resist off-center load, keep the suction cup plane horizontal, and ensure the stability of picking up and placing the box.

[0092] This linkage material handling mechanism achieves a motion trajectory that involves first moving to the bottom of the hopper, rising to pick up the material, and then directly moving it laterally. The path is a smooth curve. Compared with traditional robot paths that involve "falling down first and then rising" or "long-distance translation", the travel distance is shorter and the movements are more continuous, significantly reducing the cycle time for a single operation.

[0093] Preferably, the upper surface of the vertically movable top plate 7231 is also provided with a limiting rod, which is used to limit the plate box body, block the plate box when it is transported to the next process, and provide a forward pushing force.

[0094] Preferably, the lower ends of the first material storage adjustment plate 7121 and the material storage adjustment back plate 7124 are inwardly bent structures for placing the sheet box body.

[0095] The sheet boxes enter the sheet box storage mechanism 71 from the sheet box transfer device 6, and are received by the first storage adjustment plate 7121 and the storage adjustment back plate 7124 to achieve vertical stacking storage; the sheet box linkage picking mechanism 72 is activated, the linkage picking drive motor 7241 works, driving the linkage picking drive rod 7242 and drive cam to rotate, so that the picking horizontal moving box 722 moves horizontally. At the same time, when the drive rod rotates, it drives the linkage picking driven rod 7251 and driven cam to rotate synchronously through the drive wheel and synchronous belt on it. The two driven cams drive the picking vertical moving frame 723 to move vertically through the driven arm; The vertical moving frame 723 rises, the suction cup removes the piece box body from the piece box storage mechanism 71, and then the horizontal moving frame 722 moves horizontally to transport the piece box to the piece box climbing conveyor line 9.

[0096] This solution integrates three functional units—storage, retrieval, and delivery—with a tight spatial arrangement that shares the same planar projection area. This completely solves the problem of traditional layouts where the storage area, robotic arm work area, and conveyor line area need to be arranged sequentially, resulting in a long and cumbersome footprint. It is particularly suitable for the renovation of existing workshops with limited space.

[0097] A clamping roller feeding device is provided between the sheet box connecting rod picking device 7 and the sheet box climbing conveyor line 9. The clamping roller feeding device consists of two rotating rollers. The sheet box connecting rod picking mechanism 72, under the lateral movement of the picking transverse moving box 722, sends the sheet box body out to the two rotating rollers of the clamping roller feeding device, and then transports it to the sheet box climbing conveyor line 9, thus playing a connecting role. The clamping roller feeding device is a common structure, so it will not be described in detail.

[0098] like Figure 28-33 As shown, the carton incline conveyor line 9 is located below the main conveyor line of the system. The milk carton body, placed between the upper and lower pads, is conveyed through the main conveyor line of the system, while the carton body is conveyed through the carton incline conveyor line 9. The milk carton stacking device 8 is used to adjust the rhythm of the conveyed milk carton body so that it can be consistent with the conveying rhythm of the carton body. Thus, at the intersection of the milk carton stacking device 8 and the carton incline conveyor line 9, the milk carton body can be accurately dropped into the carton and then continue to be conveyed to the finished carton conveyor line.

[0099] Preferred, such as Figures 29-32As shown, the milk bag stacking device 8 includes a first stacking side plate 81, a second stacking side plate 82, and a milk bag stacking mechanism 83. The first stacking side plate 81 and the second stacking side plate 82 are connected by a connecting rod to form an integral mechanism, and a milk bag channel is formed between the first stacking side plate 81 and the second stacking side plate 82. The milk bags are conveyed to the milk bag channel through a milk bag tray conveying device. The milk bag stacking mechanism 83 is located between the first stacking side plate 81 and the second stacking side plate 82, and a stacking platform 84 is also provided between the first stacking side plate 81 and the second stacking side plate 82. The milk bag stacking mechanism 83 is used to stack the milk bags on the milk bag tray conveying device to the stacking platform 84. The stacking platform 84 cooperates with the milk bag stacking mechanism 83 to adjust the rhythm of milk bag pausing.

[0100] Preferably, the milk carton stacking mechanism 83 includes a stacking motor 831, a stacking drive sprocket 832555, a stacking drive chain 833, a stacking driven sprocket 834556, a stacking driven chain 835, and a stacking rod 836; the stacking motor 831 is provided on the outside of the first stacking side plate 81, and a plurality of stacking drive sprockets 832555 are provided on the inner side of the first stacking side plate 81; the stacking drive chain 833 is connected to each stacking drive sprocket. The sprockets 832555 are engaged; the inner side of the second side plate 82 of the stacking is provided with several stacking driven sprockets 834556 that correspond one-to-one with the stacking drive sprockets 832555; the stacking driven chain 835 is engaged with each stacking driven sprocket 834556; the stacking rod 836 is arranged between the stacking drive chain 833 and the stacking driven chain 835, so that the stacking motor 831 drives the stacking rod 836 to rotate with the chain.

[0101] Preferably, there are four stacking rods 836, which are used to correct the milk bags' movement during the rhythmic conveying process.

[0102] Preferably, the milk bag channel has a front section and a rear section, the front section is coordinated with the milk bag tray conveying device, and the rear section is provided with a stacking platform 84.

[0103] Preferably, the milk bag channel is equipped with a milk bag alignment mechanism 85 for correcting the conveying posture of the milk bags. It includes a first alignment plate 851, a second alignment plate 852, and alignment fixing components 853. The first alignment plate 851 is installed to the first side plate 81 of the stacking via two alignment fixing components 853, and the second alignment plate 852 is installed to the second side plate 82 of the stacking via two alignment fixing components 853. The alignment fixing components 853 can adjust the distance between the first alignment plate 851 and the second alignment plate 852. The alignment plates can guide the milk bags to automatically align during conveying, avoiding jamming or tilting caused by skewing.

[0104] Preferably, the alignment and fixing assembly 853 includes an L-shaped connecting piece 8531, an alignment handwheel 8532, an alignment threaded rod 8533, and an alignment spring 8534. The alignment threaded rod 8533 is fixedly installed on the outside of the first side plate 81 of the stacking unit. One end of the L-shaped connecting piece 8531 passes through the alignment threaded rod 8533, and the other end extends into the first side plate 81 of the stacking unit and connects to the first alignment plate 851. The alignment spring 8534 is provided between the L-shaped connecting piece 8531 and the first side plate 81 of the stacking unit. The alignment handwheel is threadedly connected to the alignment threaded rod and is used to press and adjust the L-shaped connecting piece 8531, thereby achieving the purpose of adjusting the first alignment plate 851. It can be adjusted according to different sizes of pallets, increasing adaptability.

[0105] Preferably, the second plate of the stacking platform 84 has several grooves on its surface to increase friction, preventing changes in the pallet's posture when it enters the platform. The platform is unpowered and stops immediately after the pallet enters, providing a clear starting position for the stacking rod 836 to push, ensuring consistent strokes each time.

[0106] Preferred, such as Figure 34 As shown, the incline conveyor line 9 is L-shaped and is a conveying path from bottom to top. It includes a piece box conveying mechanism 91, a piece box conveying first baffle 92, and a piece box conveying second baffle 93. The first baffle 92 and the second baffle 93 of the film box conveyor are respectively connected to the film box conveyor mechanism 91 through two spacing adjustment mechanisms 94.

[0107] Preferably, the film box conveying mechanism 91 includes two film box conveying mounting plates 911. Chain drive assemblies are provided on the two mounting plates to drive the film box conveying chain 912 to rotate. The film box conveying chain 912 is provided with several limiting rods, with each pair of limiting rods forming a workstation. The film box body is placed on the upper surface of the two film box conveying mounting plates 911, and is pushed by the limiting rods of the two film box conveying chains 912. The film box conveying mechanism 91 is a chain conveying device, a relatively common conveying structure, and therefore has not been described in detail here. In this device, by evenly arranging the limiting rods on the chain, the purpose of conveying according to a rhythmic beat can be achieved. Preferably, the first conveyor baffle 92 and the second conveyor baffle 93 of the film box have the same structure and are connected to the film box conveying mechanism 91 in the same way. The first conveyor baffle 92, the second conveyor baffle 93, and the two bias conveying mounting plates are all L-shaped, and the transition is an arc-shaped structure. Here, we will use the first conveyor baffle 92 as an example. The upper part of the first conveyor baffle 92 is provided with a lower support plate 921 and an upper blocking plate 922. The film box body is selected and conveyed by the lower support plate 921 and the upper blocking plate 922. The lower support plate 921 and the upper blocking plate 922 are also L-shaped. Because there is a curved structure during the upward conveying process of this device, if the film box passes through this part without restraint, there is a risk of the film box flying due to its own rigidity. Therefore, by setting the lower support plate 921 and the upper blocking plate 922, the film box can be conveyed smoothly.

[0108] Preferably, the spacing adjustment mechanism 94 includes a spacing adjustment handwheel 941, a spacing adjustment threaded rod 942, a spacing adjustment nut seat 943, and a spacing adjustment guide rod 944. The rotating seat is mounted on the support member. The spacing adjustment threaded rod 942 is connected to the plate box conveying first baffle 92 through the spacing adjustment nut seat 943. One end of the spacing adjustment threaded rod 942 is provided with a handwheel, and the other end is connected to the rotating seat. The spacing adjustment guide rod 944 is provided between the plate box conveying first baffle 92 and the plate box conveying mounting plate 911.

[0109] Preferably, the spacing adjustment threaded rods 942 of the two spacing adjustment mechanisms 94 on the same side are equipped with sprockets, and the two sprockets are connected by a chain, enabling the two spacing adjustment mechanisms 94 to work simultaneously. By setting the spacing adjustment mechanisms 94 to accommodate film boxes of different widths, the versatility of the equipment is greatly enhanced.

[0110] Working principle: Milk bags are conveyed from the milk bag tray conveyor to the milk bag stacking device 8. The tray containing the milk bags enters the stacking platform 84. Since the stacking platform 84 does not have a conveying function, it stops and enters a stationary state after the tray enters. At this time, the stacking rod 836 continues to rotate. When the stacking rod 836 contacts the milk bag, it will push the milk bag and the tray forward (the tray is grooved, and the milk bag placed in it can move together). At this time, the carton climbing conveyor 9 also conveys the carton body. The carton body and the milk bag are simultaneously transferred to the finished carton conveyor line at the intersection, and the milk bag falls on top of the carton body, which is convenient for subsequent folding and packaging of the carton body. Entering the finished carton conveyor line, since it can only move forward by pushing, the milk bag entering the finished carton conveyor line is determined by the milk bag stacking mechanism 83.

[0111] The sheet box folding mechanism and sheet box glue application mechanism are installed on the box frame. The sheet box folding mechanism is used to fold the conveyed sheet boxes into square boxes, and the sheet box glue application mechanism is used to apply glue to the areas on the sheet boxes that need to be glued. The sheet box folding mechanism consists of several folding guide rods and is set inside the box frame. By setting the trajectory of the folding guide rods, the sheet boxes change from an open state to a folded state after passing through. Because this folding mechanism is a relatively mature concept in product packaging lines and is already in use, it will not be described in detail here. The sheet box glue application mechanism is also a relatively mature piece of equipment. It completes the glue application work on the areas on the sheet boxes that need to be glued during conveying, which facilitates subsequent gluing and shaping.

[0112] After passing through the tablet box folding mechanism, the tablet box is folded, the milk bag is wrapped inside, and it moves toward the tablet box side leaf feeding device 10; The side vane feeding device 10 of the film box, such as Figures 35-37 As shown, it includes a first side-leaf insertion mechanism 101 and a second side-leaf insertion mechanism 102; the first side-leaf insertion mechanism 101 and the second side-leaf insertion mechanism 102 are arranged on both sides of the conveying equipment to realize the side-leaf insertion work of the film box during the conveying process. The first insert rod of the first side blade inserting device rotates counterclockwise, and the second insert rod of the second side blade inserting device rotates clockwise; the rotation direction of both corresponds to the conveying direction of the conveying equipment. The No. 1 and No. 2 feed rods rotate synchronously to achieve the feeding operation of the two side blades of the plate box; The No. 1 and No. 2 side leaf inserting mechanisms 102 are placed on both sides of the conveying equipment, which can simultaneously insert the left and right side leaves of the carton, significantly improving packaging efficiency and adapting to the rhythm of continuous production lines. The design of the No. 1 inserting rod rotating counterclockwise and the No. 2 inserting rod rotating clockwise is naturally matched with the forward direction of the carton, so that the side leaves fold and press together in motion, reducing interference and pauses and improving process continuity.

[0113] Preferably, the first side blade injection mechanism 101 and the second side blade injection mechanism 102 have the same structure. The first side blade injection mechanism 101 includes a first side blade injection mounting frame 1011, a first upper injection motor 1012, a first lower injection motor 1013, a first upper injection assembly 1014, and a first lower injection assembly 1015. The first side blade insertion mounting bracket 1011 includes a first top plate 10111 and a first bottom plate 10112. The two ends of the first top plate 10111 are respectively connected to the two ends of the first bottom plate 10112 through connecting plates. The No. 1 upper injection motor 1012 and the No. 1 lower injection motor 1013 are both installed on the upper surface of the No. 1 top plate 10111. The No. 1 upper injection assembly 1014 is installed on the lower surface of the No. 1 top plate 10111. The No. 1 lower injection assembly 1015 is installed on the upper surface of the No. 1 bottom plate 10112. The No. 1 upper injection motor 1012 is used to drive the No. 1 upper injection assembly 1014 to rotate. The No. 1 lower injection motor 1013 is used to drive the No. 1 lower injection assembly 1015 to rotate.

[0114] Preferably, the No. 1 upper driving component 1014 and the No. 1 lower driving component 1015 have the same structure. The No. 1 upper driving component 1014 includes a No. 1 driving drive sprocket 10141555, a No. 1 driving driven sprocket 10142556, a No. 1 driving chain 10143 and a No. 1 upper driving rod 10144. The first driving sprocket 10141555 and the first driven sprocket 10142556 are installed on the first top plate 10111. The first driving chain 10143 meshes with the first driving sprocket 10141555 and the first driven sprocket 10142556. The first driving sprocket 10141555 is connected to the output end of the first upper driving motor 1012. The first driving chain 10143 is provided with a plurality of first upper driving rods 10144.

[0115] The No. 1 upper driving rod 10144 of the No. 1 upper driving assembly 1014 and the No. 1 lower driving rod of the No. 1 lower driving assembly 1015 are spatially staggered. The No. 1 upper driving rod 10144 of the No. 1 upper driving assembly 1014 is used to drive the side leaf at the first end of the film box, and the No. 1 lower driving rod of the No. 1 lower driving assembly 1015 is used to drive the side leaf at the second end of the film box. The distance between adjacent No. 1 upper driving rod 10144 and No. 1 lower driving rod is always fixed and matches the size of the film box. The No. 1 upper driving rod 10144 and No. 1 lower driving rod can drive the side leaf in and hold it in place, so that the film box is firmly glued as a whole. The above describes the working principle of the first side vane feeding mechanism 101. The second side vane feeding mechanism 102 operates in the same way, and both work together. There are two side vanes at one end of the plate box, and the second side vane feeding device feeds the side vane on the other side. Figure 3 As shown.

[0116] Preferably, the first driving rod 10144 includes a first main rod 10145 and a first auxiliary rod 10146. The end of the first main rod 10145 is hinged to the first driving chain 10143, and the middle part of the first auxiliary rod 10146 is hinged to the first driving chain 10143. The ends of the first main rod 10145 and the first auxiliary rod 10146 are also hinged to each other.

[0117] Preferably, the first upper driving rod 10144 rotates with the first driving chain 10143, and rotates until the first driving chain 10143 is located at the arc of the two sprockets, and the first main rod 10145 and the first auxiliary rod 10146 are folded. Rotate until the first drive chain 10143 is positioned in a straight line between the two sprockets, with the main rod and the first auxiliary rod 10146 brackets in an open position, and the first auxiliary rod 10146 perpendicular to the first drive chain 10143.

[0118] Preferably, a support sprocket 10147 is provided between the first driving sprocket 10141555 and the first driven sprocket 10142556 to improve the stability of the straight section of the first driving chain 10143.

[0119] Working principle: After the wafer box finishes wrapping the product, it is conveyed to the side leaf insertion device. The first insertion rod 10144 of the first insertion assembly 1014 and the second insertion rod of the second insertion assembly rotate to the arc position, which is the folded state. At this time, the wafer box smoothly enters between the first side leaf insertion mechanism 101 and the second side leaf insertion mechanism 102 through the conveyor. With the conveyor and the opening of the first and second insertion rods, the two side leaves at one end of the wafer box abut against the first and second insertion rods respectively. At this time, the first lower insertion rod of the first lower insertion component 1015 and the second lower insertion rod of the second lower insertion component also move forward and become open. At this time, the film box has completely entered between the first side leaf insertion mechanism 101 and the second side leaf insertion mechanism 102. The first lower insertion rod and the second lower insertion rod are used to complete the insertion operation of the two side leaves at the other end of the film box. The side leaves of the film box have been coated with glue by the previous film box glue application mechanism. During a period of film box conveying, the four side leaves of the film box are respectively between the first upper insertion rod 10144, the first lower insertion rod, the second upper insertion rod, and the second lower insertion rod, thereby further completing the side leaf pasting and pressing operation.

[0120] Above the sheet box side leaf feeding device 10, there is also a sheet box compaction device, which is suspended on the box frame and has a compaction working surface. The film box body enters the film box side leaf feeding device 10 and also enters the film box compaction device. Its main function is to press the glued area of ​​the film box to strengthen the bonding effect. This structure has no special conveying effect, it only serves as a suspended pressure plate, so it will not be described in detail.

[0121] The principle of the upper and lower leaf feeding device of the carton is the same as that of the side leaf feeding device 10 of the carton. The only difference is that the upper and lower leaf feeding device of the carton is flipped so that it can act on the upper and lower leaves to complete the overall sealing of the packaging. After the overall sealing is completed, the material is transferred to the receiving point, and the packaging work of this system is completed.

[0122] This system also includes a padless conveyor line, which is located on the side of the pad conveyor line. This is to accommodate situations where it is not necessary to place upper and lower pads on the milk bag. During the conveying process, the milk bag is transferred to the finished product box conveyor line by the milk bag gripping and transfer device 4 and placed on top of the box. The subsequent steps are the same as the box packaging steps described above, and will not be repeated here.

[0123] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
