Description

Technical Field

[0001] This invention relates to the field of packaging machinery technology, and in particular to an automatic electric adjustable cartoning machine based on the size of the carton. Background Technology

[0002] Cartoning machines are automated packaging equipment widely used in industries such as food, pharmaceuticals, daily chemicals, electronics, and packaging products. They are primarily used to automatically fill products into pre-made boxes to complete the packaging process. Existing cartoning equipment typically includes a feeding mechanism, a suction mechanism, and a carton conveying mechanism. The feeding mechanism transports the folded boxes, the suction mechanism picks up and expands the boxes to pre-form them, and finally, the carton conveying mechanism completes the product filling and box sealing processes.

[0003] However, most existing cartoning machines are structurally designed for boxes of fixed sizes. When it is necessary to change to boxes of different sizes, manual readjustment of the feeding position, stopping structure, box suction station, and box feeding station is often required. This involves numerous adjustment steps, is complex, and the accuracy of the adjustment depends on manual experience, making it prone to inaccurate adjustments. Especially when the box size changes significantly, the folded box may shift, tilt, or become unstable during feeding, further causing problems such as box suction failure, inability to pre-form the box properly, box jamming, and misalignment during cartoning, thus affecting the overall stability of the machine and the cartoning efficiency.

[0004] Therefore, how to provide a cartoning machine that can automatically adjust the feeding position and clamping structure according to different box sizes and improve the stability of box conveying and suction has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides an automatic electric adjustable cartoning machine based on the size of the carton.

[0006] The technical solution adopted by this invention to solve its technical problem is: This invention provides an automatic electric adjustable cartoning machine based on box size, comprising a feeding mechanism, a suction mechanism, and a conveying mechanism. The feeding mechanism is used to transport folded boxes, the suction mechanism is used to pick up materials from the feeding mechanism and pre-form the folded boxes, and the conveying mechanism is used to receive the pre-formed boxes and external objects to be boxed and complete the forming and boxing. It also includes a frame, on which the feeding mechanism, suction mechanism, and conveying mechanism are all mounted. The feeding mechanism includes a first support, on which a first stop and a second driving member are provided. The second driving member is used to drive the first stop closer to or away from the first support to clamp and limit the folded box. The frame is provided with a first driving member, which is used to drive the feeding mechanism closer to or away from the suction mechanism.

[0007] Preferably, the first support is provided with a first conveying section and a second conveying section. The second conveying section is formed by bending and extending from the end of the first conveying section along its length. A second driving member is provided corresponding to the second conveying section and is used to drive the first stop member to clamp and limit the folded box body on the second conveying section. A first limiting member is provided at the end of the second conveying section away from the first conveying section. The first stop member is provided with a second limiting member for use in conjunction with the first limiting member. The free end of the second limiting member protrudes from the end face of the first stop member to be close to the side of the second conveying section. The free end of the second limiting member is arc-shaped. The protrusion of the second limiting member relative to the first stop member is... The protrusion of the first limiting member relative to the second conveying section is smaller than that of the first limiting member. The first and second conveying sections adopt a bent connection structure, which allows the folded box to form a posture transition during the conveying process. Together with the first stop, the first limiting member, and the second limiting member, the box is clamped and the end is limited, which can prevent the folded box from slipping or shifting position during the feeding process. The second limiting member is set with an arc-shaped end, and its protrusion is smaller than that of the first limiting member. This is conducive to guiding and avoiding the box during the picking and placing process, reducing the probability of interference and jamming at the edges and corners of the box, thereby improving the stability of the subsequent box suction process.

[0008] Preferably, the first support is further provided with a second stop and a third drive for driving the second stop to reciprocate. The second stop is located at the end of the first support away from the second drive in the width direction, and is used to stop one end of the folded box in the width direction. The second stop is also provided with a third stop and a linear drive, and the third stop is used to stop one side of the folded box in the thickness direction. The first conveying section and / or the second conveying section are provided with a first groove, which is strip-shaped along the width direction of the first conveying section. The first conveying section and / or the second conveying section are provided with a first rod, which is slidably disposed with the first conveying section and / or the second conveying section via the first groove. The length direction of the first rod intersects the first conveying section at an acute angle. The second stop... The first stop is adjustable along the length of the first rod. The second stop includes a first stop and a second stop for use with the first and second conveying units. The length of the first stop is parallel to the length of the first conveying unit. The third stop is located on the first stop. The second stop, the third stop, and the first rod form a multi-directional limiting structure, which can simultaneously position and constrain the folded box in multiple directions, so that boxes of different sizes can maintain a relatively stable placement posture in the feeding area. The first rod is arranged obliquely to intersect with the first conveying unit, so that the second stop can simultaneously change its lateral and longitudinal positional relationship during adjustment, thereby reducing the setting of multiple independent adjustment points and improving the adjustment efficiency and positioning consistency when changing the size of the box.

[0009] Preferably, a second trough is provided on the first conveying section, and the second trough is strip-shaped along the length of the first conveying section. A first support is provided with a conveyor belt located at the first conveying section and a fourth driving member for driving the conveyor belt. The conveyor belt is provided with teeth for abutting the folded box. The fourth driving member drives the folded box to move from the first conveying section to the second conveying section via the conveyor belt and the teeth. The second trough provides clearance space for the conveyor belt, and the teeth work together to intermittently push against the folded box, which can improve the continuity of the conveying of the box between the first and second conveying sections. The teeth can effectively abut against the edge of the box. Compared with the ordinary flat belt friction conveying method, it is not easy for slippage to occur due to the smooth surface of the box or its light weight, thereby improving the conveying accuracy and feeding cycle stability of the folded box.

[0010] Preferably, the suction box mechanism includes a fourth support, on which a sixth driving member and a disc are mounted. The disc is rotatably mounted on the fourth support, and the sixth driving member is fixedly mounted on the fourth support to drive the disc to rotate. The disc is circular, and a second rod is rotatably mounted on the disc. The rotation axis of the second rod is not collinear with the rotation axis of the disc. A third rod is located at the end of the second rod away from the disc, and the length direction of the third rod intersects the length direction of the second rod. A first adsorption member is located at the end of the third rod along its length direction. The first adsorption member is used to adsorb and place the folding box. The disc drives the second rod to rotate. Simultaneously, by utilizing the intersecting arrangement between the second and third rods, the first adsorption member can form a composite trajectory during movement, thereby meeting the requirements for picking up, transferring, and unfolding the folding box. The fact that the rotation axis of the second rod is not collinear with the rotation axis of the disc increases the range of motion of the first adsorption member, enabling the suction box mechanism to achieve a large picking and placing stroke within a limited installation space, improving the space utilization of the equipment and the flexibility of the suction box operation.

[0011] Preferably, a fifth support is fixedly mounted on the fourth support, and a first gear is fixedly mounted on the fifth support. A second gear and a third gear are rotatably mounted on the disc, and the second and third gears are meshed together. The third gear is meshed with the first gear. The output end of the sixth drive component rotates through the first gear and is fixedly connected to the disc. The end of the second rod component away from the third rod component rotates through the fourth support and is fixedly connected to the second gear. This allows the second rod component to drive the third rod component to rotate counterclockwise when the disc rotates clockwise. A linkage transmission relationship is formed between the first, second, and third gears. During the rotation of the disc, the second rod component can be driven to rotate in the opposite direction simultaneously, so that the third rod component and the first adsorption component generate a rotation effect while revolving around the central axis. This allows the folding box to simultaneously complete posture adjustment and unfolding pre-processing during the transfer process. This differential motion method helps to reduce the instantaneous impact when the box unfolds, improves the stability of the box forming, and reduces the risk of adsorption falling off.

[0012] Preferably, a fifth support is fixedly mounted on the fourth support, and a fourth rod is mounted on the fifth support. A second adsorption element is mounted on the end of the fourth rod away from the fourth support. The second adsorption element is adjustablely mounted on the fourth rod and is used in conjunction with the first adsorption element to pre-separate the folded box, preventing the two box surfaces of the folded box from adhering to each other and affecting subsequent molding operations. A sixth support is also provided on the frame, and the fifth support is slidably mounted on the sixth support. A seventh driving element is mounted on the sixth support, which is used to drive the fifth support to slide relative to the sixth support. After the second adsorption element cooperates with the first adsorption element, the two adhering box surfaces can be pre-separated during the folded box suction process, preventing the box surfaces from sticking together due to static electricity, compression, or material rebound. The fifth support can move relative to the sixth support under the action of the seventh driving element, so that the position of the second adsorption element can be adjusted according to different box sizes, thereby improving the adaptability of the pre-separation action to different specifications of boxes and reducing the situation of subsequent box-supporting failure and incomplete molding.

[0013] Preferably, the cartoning machine further includes a supply mechanism, which includes a seventh support detachably mounted on the frame. A first conveyor belt and a second conveyor belt are rotatably mounted on the seventh support. The first and second conveyor belts work together to convey food items awaiting cartoning from the outside. The seventh support also includes an eighth drive component and a ninth drive component, which drive the first and second conveyor belts respectively. A first stop plate and a second stop plate are fixedly mounted on the first and second conveyor belts respectively. The first and second stop plates have identical structures. The end of the first stop plate away from the first conveyor belt can slide relative to the second conveyor belt, and the end of the second stop plate away from the second conveyor belt can slide relative to the first conveyor belt. The first and second conveyor belts work together to form a double-sided synchronous conveying structure, which can stably guide and convey the food items awaiting cartoning. The first and second stop plates can limit and organize the food during conveying and allow changes in the distance between them to adapt to the conveying needs of food items of different sizes, improving the positional consistency of the objects awaiting cartoning when entering the cartoning station.

[0014] Preferably, the cartoning machine further includes a carton conveying mechanism, which includes an eighth bracket detachably mounted on the frame. The carton conveying mechanism also includes a first folding module and a second folding module. Folding components are provided on the sides of the first and second folding modules that are away from each other. The first and second folding modules are used for folding and sealing the two ends of the carton body via the folding components. A tenth driving component is provided on the eighth bracket. The tenth driving component is used to move the first and second folding modules closer together or further apart to accommodate carton bodies of different widths. The first folding module includes a ninth bracket, on which a carrier plate is provided. The carrier plate is located on the side of the ninth bracket closest to the second folding module to support the carton body. A stop strip is provided on the carrier plate, and the stop strip is perpendicular to the carrier plate. The first and second folding box modules are respectively equipped with a first conveying module and a second conveying module. The first and second conveying modules are respectively located on the side of the first and second folding box modules that are close to each other to accommodate boxes of different lengths. The first and second folding box modules can move closer or further apart under the action of the tenth driving component, so that the box feeding mechanism can adapt to the sealing requirements of boxes of different widths. A box support and positioning area is formed between the carrier plate and the stop strip, which helps to maintain the stable posture of the box during the packaging process. At the same time, the first and second conveying modules are respectively set on both sides of the box, which can form corresponding conveying supports according to the width of the box, thereby improving the running stability of the box during the folding and packaging process.

[0015] Preferably, the first conveying module includes a first conveyor chain and a second conveyor chain. The first and second conveyor chains are respectively provided with a first stop and a second stop for cooperative use. The stop is L-shaped to ensure that either stop can block the external box. The length of the stop is less than the length of the stop bar. The first conveying module and the second conveying module have the same structure. The eighth bracket is also provided with a first drive assembly and a second drive assembly. The first drive assembly and the second drive assembly are used to drive the two first conveyor chains and the two second conveyor chains, respectively. The first and second stop are L-shaped, ensuring that the conveyor chains can always effectively stop the box during cyclical movement, preventing the box from slipping during conveying. The length of the stop is less than the length of the stop bar, which can meet the box conveying limit requirements while reserving operating space for the folding assembly, avoiding interference between the box placement and the box conveying action, thereby improving the continuity of the box conveying and sealing action and the sealing quality.

[0016] The beneficial effects of this invention are: The feeding mechanism can clamp and limit folding boxes of different sizes and adjust its position relative to the box suction mechanism. It also works with the box suction mechanism to pick up and pre-form the folding boxes, and then the box feeding mechanism completes the subsequent boxing operation. This achieves automated adaptation of the boxing equipment to different box specifications, improves the connection stability and operation accuracy of the feeding, suction, forming and boxing processes of folding boxes, reduces problems such as box offset, jamming and unstable suction, and further improves boxing efficiency, equipment automation and overall boxing quality.

[0028] The following is a brief introduction to some relevant content, terms, or nouns involved in this application.

[0029] Reference Figures 1 to 13 An automatic electric adjustable cartoning machine based on box size includes a feeding mechanism 1, a suction mechanism 2, and a carton conveying mechanism 3. The feeding mechanism 1 is used to transport folded boxes, the suction mechanism 2 is used to take materials from the feeding mechanism 1 and pre-form the folded boxes, and the carton conveying mechanism 3 is used to receive the pre-formed boxes and external objects to be boxed and complete the forming and boxing. It also includes a frame 4, on which the feeding mechanism 1, suction mechanism 2, and carton conveying mechanism 3 are all mounted. The feeding mechanism 1 includes a first support 11, on which a first stop 12 and a second drive 121 are provided to drive the first stop 12 to move. The second drive 121 is used to drive the first stop 12 to move closer to or away from the first support 11 to clamp and limit the folded boxes. The frame 4 is provided with a first drive 41, which is used to drive the feeding mechanism 1 closer to or away from the suction mechanism 2.

[0030] Through the above structural setup, the feeding mechanism 1 can clamp and limit folding boxes of different sizes and adjust its position relative to the box suction mechanism 2. At the same time, it works with the box suction mechanism 2 to pick up and pre-form the folding boxes, and then the box conveying mechanism 3 completes the subsequent boxing operation. This achieves the automated adaptation effect of the boxing equipment to boxes of different specifications, improves the connection stability and running accuracy of the feeding, suction, forming and boxing process of folding boxes, reduces problems such as box offset, jamming and unstable suction, and further improves the boxing efficiency, the degree of automation of the equipment and the overall boxing quality.

[0031] The frame 4 is equipped with a central control mechanism 8, which is used to perform linkage control on the controllable drive structure and electrical actuator in this technical solution. The central control mechanism 8 can perform linkage control according to the preset folding box size, or it can be equipped with a photo recognition mechanism to recognize the size of the folding box, and then adaptively adjust the linkage control of each controllable drive structure and electrical actuator through the built-in algorithm.

[0032] The frame 4 is equipped with an openable door 42, which is located on the side of the cartoning machine in the direction of material flow.

[0033] Specifically, the first support 11 is provided with a first conveying section 111 and a second conveying section 112. The second conveying section 112 is formed by bending and extending from the end of the first conveying section 111 along its length. The second driving member 121 is provided corresponding to the second conveying section 112 and is used to drive the first stop member 12 to clamp and limit the folded box body on the second conveying section 112. The end of the second conveying section 112 away from the first conveying section 111 is provided with a first limiting member 113. The first stop member 12 is provided with a second limiting member 120 for use in conjunction with the first limiting member 113. The free end of the second limiting member 120 protrudes from the first stop member 12 and is close to the end face of the second conveying section 112. The free end of the second limiting member 120 is arc-shaped. The protrusion dimension of 120 relative to the first stop 12 is smaller than the protrusion dimension of the first limiter 113 relative to the second conveying part 112. The first conveying part 111 and the second conveying part 112 adopt a bent connection structure, which allows the folded box to form a posture transition during the conveying process. Together with the first stop 12, the first limiter 113 and the second limiter 120, the box is clamped and the end is limited, which can prevent the folded box from slipping or shifting position during the feeding process. The second limiter 120 is set with an arc end, and its protrusion dimension is smaller than that of the first limiter 113. This is conducive to forming a guide and avoidance during the picking and placing of the box, reducing the probability of interference and jamming at the corners of the box, thereby improving the stability of the subsequent box suction process.

[0034] The second driving member 121 is used to drive the first stop member 12 to move in a direction perpendicular to the second conveying part 112.

[0035] The second limiting member 120 is adjustablely disposed on the first stop member 12, that is, while ensuring that the straight distance between the first stop member 12 and the second conveying part 112 remains unchanged, the straight distance between the free end of the second limiting member 120 and the second conveying part 112 is adjustable.

[0036] Specifically, the first support 11 is also provided with a second stop 13 and a third drive 131 for driving the second stop 13 to reciprocate. The second stop 13 is located at the end of the first support 11 away from the second drive 121 in the width direction. The second stop 13 is used to stop one end of the folding box in the width direction. The second stop 13 is also provided with a third stop 14 and a linear drive 141. The third stop 14 is used to stop one side of the folding box in the thickness direction. The first conveying section 111 and / or the second conveying section 112 are provided with a first groove 114. The first groove 114 is strip-shaped along the width direction of the first conveying section 111. The first conveying section 111 and / or the second conveying section 112 are provided with a first rod 16. The first rod 16 is slidably disposed with the first conveying section 111 and / or the second conveying section 112 via the first groove 114. The length direction of the first rod 16 is parallel to that of the first conveying section 111. The first rod 16 is arranged in a cross configuration with an acute angle. The second stop 13 is adjustablely mounted on the first rod 16 along its length. The second stop 13 includes a first stop portion and a second stop portion for use with the first conveying unit 111 and the second conveying unit 112. The length direction of the first stop portion is parallel to the length direction of the first conveying unit 111. A third stop 14 is mounted on the first stop portion. The second stop 13, the third stop 14, and the first rod 16 form a multi-directional limiting structure, which can simultaneously position and constrain the folded box in multiple directions, so that boxes of different specifications can maintain a relatively stable placement posture in the feeding area. The first rod 16 is arranged obliquely, intersecting with the first conveying unit 111, so that the second stop 13 can simultaneously change its lateral and longitudinal positional relationship during adjustment, thereby reducing the setting of multiple independent adjustment points and improving the adjustment efficiency and positioning consistency when switching box sizes.

[0037] The third stop 14 is inclined relative to the first conveying part 111. The distance between the vertical projection of the upper end of the third stop 14 on the first conveying part 111 and the second conveying part 112 is greater than the distance between the vertical projection of the lower end of the third stop 14 on the first conveying part 111 and the second conveying part 112. The length direction of the first rod 16 is parallel to the length direction of the third stop 14.

[0038] The linear drive 141 can be a linear motor, or it can be a spring set on the second stop 13. For example, the spring drives the third stop 14 to stop the folding box through the stretching elastic force, so that the third stop 14 drives the folding box to move from the first conveying part 111 to the second conveying part 112.

[0039] The first support 11 is also provided with a fourth stop 15, which is used to cooperate with the second stop 13 to limit and stop both ends of the folding box. The fourth stop 15 can be driven manually or by other driving components.

[0040] Specifically, a second trough 115 is provided on the first conveying section 111. The second trough 115 is strip-shaped along the length of the first conveying section 111. A conveyor belt 17 located at the first conveying section 111 and a fourth driving member 171 for driving the conveyor belt 17 are provided on the first support 11. The conveyor belt 17 is provided with teeth 172 for abutting the folded box. The fourth driving member 171 drives the folded box from the first conveying section 111 to the second conveying section 112 via the conveyor belt 17 and the teeth 172. The second trough 115 provides clearance space for the conveyor belt 17. In conjunction with the teeth 172, the folded box is intermittently pushed, which can improve the continuity of the conveying of the box between the first conveying section 111 and the second conveying section 112. The teeth 172 can effectively abut against the edge of the box. Compared with the ordinary flat belt friction conveying method, it is not easy for the box surface to slip due to its smoothness or light weight, thereby improving the conveying accuracy and feeding cycle stability of the folded box.

[0041] A second support 18 is slidably mounted on the first support 11, and a third support 19 is slidably mounted on the second support 18. A first driving member 41 is mounted on the third support 19 and is mounted on the frame 4 via the third support 19. The first driving member 41 is used to drive the second support 18 to slide relative to the third support 19. A fifth driving member 181 is provided on the second support 18 to drive the first support 11 to slide relative to the second support 18. The direction of movement of the first support 11 driven by the fifth driving member 181 intersects the direction of movement of the second support 18 driven by the first driving member 41.

[0042] Specifically, the suction box mechanism 2 includes a fourth support 21, on which a sixth driving member 211 and a disc 212 are mounted. The disc 212 is rotatably mounted on the fourth support 21. The sixth driving member 211 is fixedly mounted on the fourth support 21 to drive the disc 212 to rotate. The disc 212 is circular. A second rod 22 is rotatably mounted on the disc 212. The axis of rotation of the second rod 22 is not collinear with the axis of rotation of the disc 212. A third rod 23 is mounted at the end of the second rod 22 away from the disc 212. The length direction of the third rod 23 intersects the length direction of the second rod 22. The end is provided with a first adsorption member 231, which is used to adsorb and place the folding box. The disc body 212 drives the second rod body 22 to rotate. At the same time, by utilizing the cross arrangement relationship between the second rod body 22 and the third rod body 23, the first adsorption member 231 can form a compound trajectory during the movement, thereby meeting the needs of picking up, transferring and unfolding the folding box. The rotation axis of the second rod body 22 and the disc body 212 are not collinear, which can increase the movement range of the first adsorption member 231, so that the box suction mechanism 2 can still achieve a large picking and placing stroke within the limited installation space, improving the space utilization of the equipment and the flexibility of the box suction action.

[0043] The length direction of the third rod 23 intersects the length direction of the second rod 22, and the angle of intersection is preferably 90 degrees.

[0044] The third rod body 23 is provided with a third groove 233 for the air tube to pass through. The third rod body 23 is hollow inside to supply air to the first adsorption element 231. The air tube is a hollow tube for connecting the adsorption element with the external negative pressure generating element.

[0045] The third rod body 23 is also provided with a limiting plate 232, which is L-shaped and is used to help limit and stop the folded box body from the outside.

[0046] The first adsorption element 231 is provided in two sets, and the two sets of first adsorption elements 231 are respectively provided at both ends of the third rod element 23 in the length direction.

[0047] Specifically, a fifth bracket 24 is fixedly mounted on the fourth bracket 21, and a first gear 241 is fixedly mounted on the fifth bracket 24. A second gear 242 and a third gear 243 are rotatably mounted on the disc body 212. The second gear 242 and the third gear 243 are meshed together, and the third gear 243 is meshed with the first gear 241. The output end of the sixth driving member 211 rotatably passes through the first gear 241 and is fixedly connected to the disc body 212. The end of the second rod member 22 away from the third rod member 23 rotatably passes through the fourth bracket 21 and is fixedly connected to the second gear 242, so as to allow the disc body 212 to rotate clockwise. When rotating, the second rod 22 drives the third rod 23 to rotate counterclockwise. The first gear 241, the second gear 242 and the third gear 243 form a linkage transmission relationship. During the rotation of the disc 212, the second rod 22 can be driven to rotate in the opposite direction, so that the third rod 23 and the first adsorption component 231 will rotate on their own axis while revolving around the sun. This allows the folded box to complete the posture adjustment and unfolding pre-processing simultaneously during the transfer process. This differential motion method helps to reduce the instantaneous impact when the box unfolds, improve the stability of the box forming, and reduce the risk of adsorption falling off.

[0048] Specifically, a fifth support 24 is fixedly mounted on the fourth support 21, and a fourth rod 25 is mounted on the fifth support 24. A second suction member 251 is mounted on the end of the fourth rod 25 away from the fourth support 21. The second suction member 251 is adjustablely mounted on the fourth rod 25 and is used in conjunction with the first suction member 231 to pre-separate the folded box body to prevent the two sides of the folded box body from adhering to each other and affecting subsequent forming operations. A sixth support 26 is also mounted on the frame 4, and the fifth support 24 is slidably mounted on the sixth support 26. A seventh driving member is mounted on the sixth support 26. 261, the seventh driving component 261 is used to drive the fifth support 24 to slide relative to the sixth support 26. After the second adsorption component 251 cooperates with the first adsorption component 231, it can pre-separate the two attached box surfaces during the folding box suction process to avoid the box surfaces from sticking together due to static electricity, squeezing or material rebound. The fifth support 24 can move relative to the sixth support 26 under the action of the seventh driving component 261, so that the position of the second adsorption component 251 can be adjusted according to different box sizes, thereby improving the adaptability of the pre-separation action to different specifications of boxes and reducing the subsequent box support failure and incomplete molding.

[0049] A second block 272 is fixedly mounted on the disc body 212. The second block 272 is sleeved on the second rod body 22 and rotates relative to the second rod body 22. A first block 271 is fixedly mounted on the second rod body 22 and rotates relative to the second block 272. A third block 273 is fixedly mounted on the first gear 241 and rotates relative to the output end of the sixth drive member 211. Airflow paths are provided in the first block 271, the second block 272, and the third block 273. The airflow path in the first block 271 is connected to the airflow path in the second block 272. The first adsorption member 231 is connected to the airflow path in the first block 271 via an air pipe. An airflow path is also provided on the output end of the sixth drive member 211. The airflow path in the second block 272 is connected to the airflow path on the third block 273 via the airflow path on the output end of the sixth drive member 211.

[0050] The first block 271, the second block 272, and the third block 273 are rotating air passage structures.

[0051] Specifically, the cartoning machine also includes a supply mechanism 5, which includes a seventh support 51 detachably mounted on the frame 4. A first conveyor belt 52 and a second conveyor belt 53 are rotatably mounted on the seventh support 51. The first conveyor belt 52 and the second conveyor belt 53 work together to convey food items to be cartoned from the outside. The seventh support 51 also includes an eighth drive member 522 and a ninth drive member 532, which drive the first conveyor belt 52 and the second conveyor belt 53 respectively. A first stop plate 521 and a second stop plate 531 are fixedly mounted on the first conveyor belt 52 and the second conveyor belt 53 respectively. The first stop plate 521 has the same structure as the second stop plate 531. The end of the first stop plate 521 away from the first conveyor belt 52 can be slidably set relative to the second conveyor belt 53. The end of the second stop plate 531 away from the second conveyor belt 53 can be slidably set relative to the first conveyor belt 52. The first conveyor belt 52 and the second conveyor belt 53 cooperate to form a double-sided synchronous conveying structure, which can stably guide and convey the food to be boxed. The first stop plate 521 and the second stop plate 531 can limit and organize the food during the conveying process, and allow the distance between them to change, so as to adapt to the conveying needs of food of different sizes and improve the positional consistency of the object to be boxed when it enters the boxing station.

[0052] The width of the first stop plate 521 above the first conveyor belt 52 is equal to the width of the first stop plate 521 above the second conveyor belt 53, and the width of the second stop plate 531 above the first conveyor belt 52 is equal to the width of the first stop plate 521 above the second conveyor belt 53.

[0053] Specifically, the cartoning machine also includes a carton conveying mechanism 3, which includes an eighth support 31 detachably mounted on the frame 4. The carton conveying mechanism 3 also includes a first folding module 32 and a second folding module 33. Folding components 320 are provided on the sides of the first folding module 32 and the second folding module 33 that are far apart from each other. The first folding module 32 and the second folding module 33 are used for folding and sealing the two ends of the carton body via the folding components 320. A tenth driving member 34 is provided on the eighth support 31. The tenth driving member 34 is used to move the first folding module 32 and the second folding module 33 closer together or further apart to adapt to carton bodies of different widths. The first folding module 32 includes a ninth support 321, on which a carrier plate 322 is provided. The carrier plate 322 is located on the side of the ninth support 321 closest to the second folding module 33 to support the carton body. A stop strip 32 is provided on the carrier plate 322. 3. The stop strip 323 is set perpendicular to the carrier plate 322; the first folding box module 32 and the second folding box module 33 are respectively provided with a first conveying module 35 and a second conveying module 36. The first conveying module 35 and the second conveying module 36 are respectively set on the side of the first folding box module 32 and the second folding box module 33 that are close to each other, so as to adapt to the box body of different lengths. The first folding box module 32 and the second folding box module 33 can move closer or further away from each other under the action of the tenth driving member 34, so that the box feeding mechanism 3 can adapt to the sealing requirements of boxes of different widths; a box body support and positioning area is formed between the carrier plate 322 and the stop strip 323, which is conducive to maintaining the stable posture of the box body during the sealing process; at the same time, the first conveying module 35 and the second conveying module 36 are respectively set on both sides of the box body, which can form corresponding conveying support according to the width of the box body, thereby improving the running stability of the box body during the folding and sealing process.

[0054] In this embodiment, at least one of the first folding box module 32 and the second folding box module 33 is movably arranged relative to the frame 4. The folding box assembly 320 is a well-known technology in the existing boxing related fields. The sealing purpose in this technical solution can be directly achieved by using the existing technology, so it will not be described in detail here.

[0055] Specifically, the first conveying module 35 includes a first conveyor chain 351 and a second conveyor chain 352. The first conveyor chain 351 and the second conveyor chain 352 are respectively provided with a first stop 3511 and a second stop 3521 for cooperative use. The stop portions are L-shaped to ensure that either stop portion can block the external box. The length of the stop portion is smaller than the length of the stop strip 323. The first conveying module 35 has the same structure as the second conveying module 36. The eighth bracket 31 is also provided with a first drive assembly 37 and a second drive assembly 38. Component 38 is used to drive two first conveyor chains 351 and two second conveyor chains 352 respectively. The first stop part 3511 and the second stop part 3521 are set with an L-shaped structure so that the conveyor chains can always effectively stop the box during the cyclic movement, and prevent the box from slipping during the conveying process. The length of the stop part is smaller than the length of the stop bar 323, which can meet the box conveying limit requirements while reserving operating space for the folding box assembly 320, and avoid the box placement from interfering with the box conveying action, thereby improving the continuity of the box conveying and sealing action and the sealing quality.

[0056] The first folding box module 32 and the second folding box module 33 are each provided with a discharge component 39 at the end for material discharge. The two discharge components 39 are located on the side of the first folding box module 32 and the second folding box module 33 that are close to each other.

[0059] In this technical solution, all structures used to limit and guide the box can have chamfers at their ends to facilitate the entry of the box; this will not be elaborated further here.

[0060] Example 2 Embodiment 2 of this application can be implemented alone or in combination with Embodiment 1 described above, and this application does not impose any restrictions.

[0061] An automatic electric adjustable cartoning machine based on box size includes a feeding mechanism 1, a suction mechanism 2, and a conveying mechanism 3. The feeding mechanism 1 is used to transport folded boxes, the suction mechanism 2 is used to take materials from the feeding mechanism 1 and pre-form the folded boxes, and the conveying mechanism 3 is used to receive the pre-formed boxes and external objects to be boxed and complete the forming and boxing. It also includes a frame 4, on which the feeding mechanism 1, suction mechanism 2, and conveying mechanism 3 are all mounted. The feeding mechanism 1 includes a first support 11, on which a first stop 12 and a second drive 121 are provided to drive the first stop 12 to move. The second drive 121 is used to drive the first stop 12 to move closer to or away from the first support 11 to clamp and limit the folded boxes. The frame 4 is provided with a first drive 41, which is used to drive the feeding mechanism 1 closer to or away from the suction mechanism 2.

[0062] Specifically, the first support 11 is provided with a first conveying section 111 and a second conveying section 112. The second conveying section 112 is formed by bending and extending from the end of the first conveying section 111 along its length. The second driving member 121 is provided corresponding to the second conveying section 112 and is used to drive the first stop member 12 to clamp and limit the folded box body on the second conveying section 112. The end of the second conveying section 112 away from the first conveying section 111 is provided with a first limiting member 113. The first stop member 12 is provided with a second limiting member 120 for use in conjunction with the first limiting member 113. The free end of the second limiting member 120 protrudes from the first stop member 12 and is close to the end face of the second conveying section 112. The free end of the second limiting member 120 is arc-shaped. The protrusion dimension of 120 relative to the first stop 12 is smaller than the protrusion dimension of the first limiter 113 relative to the second conveying part 112. The first conveying part 111 and the second conveying part 112 adopt a bent connection structure, which allows the folded box to form a posture transition during the conveying process. Together with the first stop 12, the first limiter 113 and the second limiter 120, the box is clamped and the end is limited, which can prevent the folded box from slipping or shifting position during the feeding process. The second limiter 120 is set with an arc end, and its protrusion dimension is smaller than that of the first limiter 113. This is conducive to forming a guide and avoidance during the picking and placing of the box, reducing the probability of interference and jamming at the corners of the box, thereby improving the stability of the subsequent box suction process.

[0063] The second driving member 121 is used to drive the movement direction of the first stop member 12 to intersect with the second conveying section 112, with the included angle being an acute angle. That is, when the first stop member 12 is away from the second conveying section 112, the distance between the vertical projection of the first stop member 12 on the second conveying section 112 and the first conveying section 111 is greater than the distance between the vertical projection of the first stop member 12 on the second conveying section 112 and the first conveying section 111 when the first stop member 12 is close to the second conveying section 112.
