The in-place inspection component 223 is used to detect whether there is box material stored in the release gap. Based on whether there is box material stored in the release gap detected by the in-place inspection component 223, the belt conveying component 222 is controlled to drive the box material on the storage station 211 to move until the box material enters the release gap.

[0105] The in-place inspection component 223 includes an in-place swing plate 224, an in-place inspection plate 225, a slot-shaped photoelectric 226 and a second tension spring 227; the in-place swing plate 224 is hinged to the end of the belt mounting frame 221, and the in-place swing plate 224 has a toggle portion, which extends into the material storage station 211. When there is box material stored in the release gap, the box material pushes the in-place swing plate 224 to rotate to the first angle through the toggle portion, and when there is no box material in the release gap, the in-place swing plate 224 rotates to the second angle; one end of the second tension spring 227 is connected to the in-place swing plate 224, and the other end is connected to the belt mounting frame 221, and the tension spring provides an elastic force to drive the in-place swing plate 224 to rotate from the first angle to the second angle; the in-place inspection plate 225 is connected to the in-place swing plate 224, and the slot-shaped photoelectric 226 is fixed to the end of the belt mounting frame 221.

[0106] When there is no box material in the release gap, the in-place swing plate 224 rotates to the second angle, and the in-place swing plate 224 drives the in-place inspection plate 225 to disconnect from the slot-shaped photoelectric 226. The slot-shaped photoelectric 226 sends a feeding signal to control the belt conveyor assembly 222 to drive the box material on the storage station 211 to move until the box material enters the release gap, contacts the toggle part, and pushes the in-place swing plate 224 to rotate to the first position.

[0107] The structure of the second belt assembly 23 is consistent with that of the first belt assembly 22 , and the two are arranged relative to each other, which will not be described in detail here.

[0108] The first material pressing component 24 of this embodiment includes a material pressing mounting frame, which is fixed on the first material pressing mounting plate 212; a residual material detection sensor is installed on the first material pressing component 24, and when the box material on the material storage station 211 drops to a preset number, the residual material detection sensor is triggered to send a material replenishment signal.

[0109] The first pressing assembly 24 also includes a pressing plate seat 243, which is connected to the pressing mounting frame via a slider guide mechanism. A spring balancer 244 is arranged between the pressing plate seat 243 and the pressing mounting frame, and the spring balancer 244 provides an elastic force to drive the pressing plate seat 243 to move from the feeding inlet to the box material inlet 11.

[0110] The rear pressure plate 241 is rotatably connected to the pressure plate seat 243 through the pressure plate rod 242. An elastic member is provided at the connection between the pressure plate rod 242 and the pressure plate seat 243. The elastic member can be a torsion spring or a tension spring.

The push plate seat 245 is connected to the material pressing mounting frame through a slider guide rail mechanism. The push plate driving structure 246 is linked with the push plate seat 245. The push plate driving structure 246 drives the push plate seat 245 to move relative to the material pressing mounting frame. The rubber-coated screw on the side of the push plate seat 245 contacts the material pressing plate seat 243, driving the material pressing plate seat 243 to translate to the replenishing inlet.

[0112] Specifically, the inlet belt conveyor 31 in this embodiment is mainly responsible for conveying the strip boxes. The input end of the inlet belt conveyor 31 is used to connect with the strip box supply equipment, and the other end forms a lifting station. The strip boxes are transported to the lifting station through the inlet belt conveyor 31. The stacking and lifting device 32 is arranged at the bottom of the lifting station; the stacking station 16 is formed in the stacking groove device 33, and the stacking station 16 is arranged above the lifting station;

[0113] During use, the strip boxes are conveyed by the inlet belt conveyor 31, and the strip boxes are continuously transported from the input end to the lifting station by the inlet belt conveyor 31; the strip boxes on the lifting station are continuously lifted upward into the stacking station 16 through the stacking and lifting device 32. During this process, the strip boxes are lifted layer by layer from the bottom of the stacking station 16, performing vertical stacking. The cycle is repeated until the stacking reaches a predetermined height, realizing the automatic stacking of the strip boxes into stacks in the stacking groove device 33; the strip box stacking component 30 in this embodiment can replace the work of stacking the strip boxes in the process of manual packing and sealing, effectively avoiding the low work efficiency of manual operation, and easily scratching the appearance of the strip boxes and the possible situation that the strip boxes in the box have inconsistent directions, improving the production efficiency and the quality of strip box stacking.

[0114] The inlet belt conveyor 31 in this embodiment is realized by a synchronous belt conveying mechanism. The inlet belt conveyor 31 further includes a guardrail. The guardrail is arranged between the input end of the inlet belt conveyor 31 and the lifting station. The guardrail limits the two ends of the strip boxes, restricting the strip boxes in the conveying direction of the inlet belt conveyor 31 to prevent the strip boxes from falling during the transportation of the inlet belt conveyor 31.

[0115] The strip boxes can be transported closely to each other on the entrance belt conveyor 31. When a predetermined number of strip boxes enter the lifting station, they are lifted upward by the stacking lifting device 32 and enter the stacking slot device 33 to become a separate strip box layer; in some other embodiments, there may be gaps between the strip boxes during the transportation process. In order to make the single-layer strip boxes more compact, an intercepting mechanism can be set at the end of the lifting station close to the output of the entrance belt conveyor 31 to intercept and gather the strip boxes in front of the intercepting mechanism, that is, within the lifting station; the intercepting mechanism can be a telescopic block or a rotating block extending from the conveying area of ​​the entrance belt conveyor 31, or it can be formed at the bottom of the stacking slot device 33 close to the conveying direction of the entrance belt conveyor 31, so that the strip boxes can automatically gather below the stacking station 16.

[0116] The stacking jacking device 32 of this embodiment includes a jacking mounting frame 321, a jacking assembly and a jacking drive assembly 322; the jacking mounting frame 321 is fixed to the bottom of the entrance belt conveyor 31, and the jacking assembly includes a jacking connecting plate, a first jacking plate 323 and a second jacking plate 324. The jacking connecting plate is slidably connected to the jacking mounting frame 321 through a first slider guide mechanism, so that the jacking connecting plate can be translated back and forth in the height direction relative to the jacking mounting frame 321.

[0117] The first lifting plate 323 and the second lifting plate 324 are respectively fixed at the two ends of the lifting connecting plate; the lifting driving assembly 322 is connected to the lifting connecting plate in transmission; the lifting driving assembly 322 provides power to drive the lifting connecting plate to translate back and forth in the height direction, thereby driving the first lifting plate 323 and the second lifting plate 324 at both ends to lift the two ends of the strip box, and push the strip box on the lifting station upward into the stacking station 16.

[0118] The first lifting plate 323 and the second lifting plate 324 are both T-shaped. The first lifting plate 323 and the second lifting plate 324 can be extended from the opposite sides of the conveyor belt to lift the two ends of the box. An escape area can also be set on the conveyor belt. The first lifting plate 323 and the second lifting plate 324 extend from the escape area to lift the middle part of the box so that it can be lifted smoothly into the stacking station 16. At the same time, it will not interfere with the conveying effect of the entrance belt conveyor 31 on the box, and the structure is compact.

[0119] The jacking drive assembly 322 of the present embodiment includes a jacking motor, a swing arm and a jacking connecting rod. The jacking motor is fixed to the jacking mounting frame 321 through a motor mounting seat. The jacking motor is hinged to the end of the swing arm through a planetary reducer, and the other end of the swing arm is hinged to the jacking connecting plate through the jacking connecting rod. The swing arm is driven to swing by the jacking motor, and the swing arm converts the rotating pair into the moving pair of the jacking connecting plate through the jacking connecting rod, so that the jacking connecting plate can be translated back and forth in the height direction.

[0120] The stacking slot device 33 of this embodiment includes a stacking substrate 34, a first stacking component 35, and a second stacking component 36; the stacking substrate 34 is fixed to the bottom of the inlet belt conveyor 31, and the first stacking component 35 and the second stacking component 36 are respectively arranged on both sides of the lifting station, and the two ends of the strip box are supported by the first stacking component 35 and the second stacking component 36 to fix the strip box in the stacking station 16.

[0121] The first stacking component 35 includes a first side frame 351, and the second stacking component 36 includes a second side frame 361; the first side frame 351 and the second side frame 361 are slidably connected to the stacking substrate 34 through a second slider guide mechanism; so that the first side frame 351 and the second side frame 361 can approach or move away from the lifting station.

[0122] Specifically, the stacking slot device 33 further includes a synchronous translation component 38; the synchronous translation component 38 includes a torsion plate, the torsion plate is rotatably connected to the stacking substrate 34, one end of the torsion plate is hinged to the first side frame 351 through a connecting rod, and the other end is hinged to the second side frame 361 through a connecting rod; the synchronous translation component 38 further includes a translation lead screw, the translation lead screw is connected to the stacking substrate 34 through a translation lead screw connection seat, one end of the translation lead screw is connected with a translation handwheel, and the other end is screwed to the second side frame 361; a locking member is arranged at the connection between the translation lead screw and the translation lead screw connection seat, and the locking member locks the relative positions of the translation lead screw and the translation lead screw connection seat by means of clamping the shaft.

[0123] The translation handwheel is driven to rotate the translation lead screw, so that the second side frame 361 translates relative to the stacking substrate 34, driving the second stacking component 36 to approach or move away from the lifting station; the translation of the second side frame 361 drives the torsion plate to rotate at the same time, and the rotation of the torsion plate drives the first side frame 351 to translate relative to the stacking substrate 34, driving the first stacking component 35 to approach or move away from the lifting station synchronously, so that the stacking slot device 33 can adapt to strip boxes of different lengths.

[0124] Further, the first stacking component 35 further includes several groups of wedges 352, a rotating shaft fixing seat 353 and a first tension spring 354; several groups of wedges 352, a rotating shaft fixing seat 353 and a first tension spring 354 are linearly arrayed in the length direction of the first side frame 351.

[0125] The rotating shaft fixing seat 353 is connected to the first side frame 351. A rotating shaft is connected to the bottom of the wedge block 352, and the rotating shaft is hinged to the rotating shaft fixing seat 353, so that the wedge block 352 can rotate relative to the first side frame 351. The wedge block 352 has a first position and a second position. The first position is that the wedge block 352 rotates into the stacking station 16 to support the end of the strip box. The second position is that the wedge block 352 rotates out of the stacking station 16 to avoid the passage for the strip box to enter the stacking station 16 from the lifting station. One end of the first tension spring 354 is connected to the wedge block 352, and the other end is connected to the first side frame 351. The first tension spring 354 provides an elastic force to drive the wedge block 352 to reset from the second position to the first position.

[0126] In this embodiment, a guiding inclined surface 3521 is formed on one side of the wedge block 352 close to the lifting station. During the process of the strip box being lifted upward from the lifting station, it contacts the guiding inclined surface 3521 and pushes the wedge block 352 from the second position to the first position. A supporting surface 3522 is formed on one side of the wedge block 352 close to the lifting station. The supporting surface 3522 is horizontally arranged. After the strip box is pushed into the stacking station 16, the wedge block 352 quickly resets to the first position under the action of the first tension spring 354, and the end of the strip box stably sits on the supporting surface 3522 to provide stable support for the strip box stack. A limiting portion 3523 can also be provided at the top of the wedge block 352. When the wedge block 352 rotates to the first position to support the end of the strip box, the limiting portion 3523 abuts against the first side frame 351 to limit the further rotation of the wedge block 352, improve the load-bearing capacity of the wedge block 352, and enable the stacking groove device 33 to carry more strip box stacks with higher grammage. A number of buffer silica gel particles 3524 are evenly distributed at the contact position between the limiting portion 3523 and the first side frame 351. In this way, the impact force generated by the wedge block 352 when resetting from the second position to the first position on the first side frame 351 can be reduced, the service life of the equipment can be improved, and the noise during the operation of the equipment can be reduced at the same time.

The glue-sealing machine core 6214 and the glue-pressing machine core 6215 are respectively rotatably connected to one ends of the glue-sealing core support rod 6212 and the glue-pressing core support rod 6213 close to the case-sealing station 15. The other ends of the glue-sealing core support rod 6212 and the glue-pressing core support rod 6213 are hinged by a linkage rod. Thus, both the glue-sealing core support rod 6212 and the glue-pressing core support rod 6213 can rotate on the glue-sealing machine core frame 6211, driving the glue-sealing machine core 6214 and the glue-pressing machine core 6215 at the ends to extend into or retract from the case-sealing station 15. An elastic member is arranged between the glue-sealing core support rod 6212 and the glue-sealing machine core frame 6211, and the elastic member provides an elastic force to drive the glue-sealing machine core 6214 to extend into the case-sealing station 15.

[0179] The bottom end of the glue supply roller 6217 is fixed to the glue-sealing substrate. A case-sealing tape roll is sleeved on the glue supply roller 6217. The case-sealing tape roll has a case-sealing tape. The case-sealing tape extends to the surface of the glue-sealing machine core 6214 after passing through a plurality of guide rollers and is attached to the connection position of the upper case flap and the lower case flap of the carton through the glue-sealing machine core 6214. The tape cutting member 6216 is elastically connected to the glue-sealing machine core frame 6211 through a tool rest seat, and the tape cutting member 6216 is driven by the tool rest seat to extend out to cut the case-sealing tape.

[0180] The case head glue-sealing device 62 further includes a guide plate assembly 622. The guide plate assembly 622 includes an upper guide plate and a lower guide plate. When the carton passes through the case-sealing station 15, the guide plate assembly 622 guides the carton and guides it to be in circumferential contact with the glue-sealing machine core 6214 and the glue-pressing machine core 6215. The glue-sealing machine core 6214 extending into the case-sealing station 15 first contacts the front end of the case body, attaches the case-sealing tape to the front end of the case body. As the carton pushing device 61 pushes the carton, the case body of the carton presses the glue-sealing machine core 6214 to make the glue-sealing core support rod 6212 rotate, driving the glue-sealing machine core 6214 to retract, contacting the connection position of the upper case flap and the lower case flap, and attaching the case-sealing tape to the connection position of the upper case flap and the lower case flap. When the carton pushing device 61 pushes the carton to be separated from the glue-pressing machine core 6215, the glue-sealing machine core 6214 extends into the case-sealing station 15 under the action of the elastic force and attaches the case-sealing tape to the rear end of the case body. At the same time, during the pushing process of the carton, it contacts the tool rest seat, pushing the tool rest seat to retract into the glue-sealing machine core frame 6211. When the carton passes through, the tool rest seat loses the thrust of the carton and drives the tape cutting member 6216 to pop out to cut the case-sealing tape. At the same time, the glue-pressing machine core 6215 contacts the front end of the case body, the connection position of the upper case flap and the lower case flap, and the rear end of the case body in sequence during the pushing process of the carton, pressing the case-sealing tape and the carton together to improve the firmness of case sealing.

[0181] Furthermore, the head box sealing device 62 further includes a second roller assembly 623. The second roller assembly 623 includes a roller lifting and adjusting frame, a roller seat fixing plate, a second roller seat, and a second non-powered roller. The roller lifting and adjusting frame is fixed to the top of the sealing machine core frame 6211. The roller seat fixing plate is connected to the roller lifting and adjusting frame through a pulling groove and a fastener, so that the roller seat fixing plate can be adjusted in the height direction of the roller lifting and adjusting frame. The second roller seat is fixed to the bottom of the roller seat fixing plate, and a plurality of the second non-powered rollers are linearly arranged at the bottom of the second roller seat. The second non-powered roller is used to contact the top of the cardboard box, limit the height of the cardboard box, and restrict the cardboard box on the box support frame 13.

[0182] The tail box sealing device 63 has the same structure as the head box sealing device 62, and the two are oppositely arranged on both sides of the box support frame 13. Those skilled in the art can understand this and will not be elaborated here.

Then, the sealed carton is conveyed out through the roller conveyor 90. There is no need for manual intervention from the replenishment of the carton library component 20 to the final output of the carton.

[0190] Embodiment 3:

[0191] Based on Embodiment 1, this embodiment provides a method for packing and sealing small cigarette cartons, including the following steps:

[0192] Stock preparation step: Provide the cigarette carton small packing and sealing machine described in Embodiment 1;

[0193] Debugging step: The debugging step includes the debugging of the carton library component 20, the debugging of the cigarette carton palletizing component 30, the debugging of the flaring device 49, and the debugging of the carton sealing component 60.

[0194] Debugging of the carton library component 20: Based on the width of the carton material, adjust the distance between the first carton pressing mounting plate, the first belt mounting plate 213, the second belt mounting plate 214, and the second carton pressing mounting plate respectively through the first box library adjusting component 216; Based on the height of the carton material, adjust the distance between the upper carton blocking component and the lower carton blocking component through the longitudinal adjusting shaft 261; Supply carton materials to the carton library storage station 211;

[0195] Debugging of the cigarette carton palletizing component 30: Based on the length of the cigarette carton, adjust the distance between the first stacking component 35 and the second stacking component 36 through the synchronous translation component 38; Based on the number of single-layer cigarette carton pallets, adjust the distance between the rear sliding baffle 372 and the front fixed baffle 371 through the baffle handwheel 376;

[0196] Debugging of the flaring device 49: Based on the width of the carton, adjust the distance between the first flaring component 44 and the second flaring component 45 through the flaring width adjusting handwheel 443; Based on the height of the carton, adjust the distance between the upper guide plate component 622 and the lower guide plate component 622 through the flaring height adjusting handwheel;

[0197] Debugging of the case-sealing component 60: Based on the width of the carton, adjust the distance between the carton-head adjustment base plate 661 and the carton-tail adjustment base plate 671 through the carton-tail adjustment handwheel; based on the position of the docking joint of the upper carton flap and the lower carton flap of the carton, adjust the height of the carton-head pressing device 64 through the carton-pressing adjustment handwheel, adjust the height of the carton-tail pressing device 65, adjust the height of the carton-head sealing device 62 through the sealing adjustment handwheel, and adjust the height of the carton-tail sealing device 63.

[0198] Steps of strip carton palletizing: Continuously convey the strip cartons to the stacking lifting device 32 by the inlet belt conveyor 31; continuously lift the strip cartons upward into the palletizing station 16 by the stacking lifting device 32. During this process, the strip cartons are lifted layer by layer from the bottom of the palletizing station 16 for vertical palletizing, and the reciprocating cycle continues until the stacking reaches the predetermined height.

[0199] Steps of case opening: The adsorption component 412 sucks the upper half of the case material. That is, after the top of the carton is adsorbed, the case-dragging component 411 starts to drag the adsorption component 412 towards the packing station 14. After moving a certain distance, the adsorption driving part 4124 extends, causing the suction cup holder 4123 to move downward while moving backward. Finally, the case material is unfolded into a carton under the guiding action of the downward pressure and the case-blocking rod 413, and the unfolded carton is positioned at the packing station 14.

[0200] Steps of carton-tail folding: After the carton is fully opened to the packing station 14, the inner-page lifting driving part 582 extends. First, the carton-tail upper carton flap is lifted by the carton-picking plate of the carton-picking component 55, and then the two side flaps of the carton tail are folded inward as the inner pages by the first inner-page folding plate 583 and the second inner-page folding plate 584 at both ends of the inner-page folding component 58. After the folding of the carton-tail side flaps is completed, the inner-page folding component 58 and the carton-picking component 55 are reset. Then, the carton-tail lower-page folding plate 572 of the carton-tail lower-page folding component 57 and the carton-tail upper-page folding plate 542 of the carton-tail upper-page folding component 54 fold and hold the carton-tail lower page and the carton-tail upper page of the carton as the outer pages.

[0201] Steps of packing and case folding: When the carton is successfully unfolded, the flaring base plate driving part 46 drives the flaring base plate 43 to move the first flaring component 44 and the second flaring component 45 into the carton, so that the free ends of the flaring upper guide plate 4441 and the flaring lower guide plate 4451 enter the range of the carton flaps.

[0202] Then, the guide plate driving part 447 drives the flaring upper guide plate 4441 to open, and at the same time, the universal coupling 446 drives the flaring lower guide plate 4451 to open. Then, the pallet driving part drives the pallet body to support the lower carton flap upward to prevent the lower carton flap from opening downward when the strip carton stack enters the carton, which affects the entry of the strip cartons; the buffer suction cups of the page-sucking component 52 suck and hold the upper carton flap of the carton head.

[0203] The front movable baffle 373 of the stacking slot device 33 rotates to be in the same plane as the front fixed baffle 371, and the rear movable baffle 374 rotates to be in the same plane as the rear sliding baffle 372, ensuring that the strip box will not collapse when the strip box is pushed;

[0204] The palletizing device 42 pushes the strip box stack into the inside of the carton through the packing channel 17. After the packing process is completed, the flaring device 49 retracts. Then, the inner page folding assembly 58 of the bottom device 53 of the carton head located at the carton head folds the two side pages of the carton head of the carton inward as the inner pages through the folding plate. Then, the inner page folding assembly 58 and the page sucking assembly 52 are reset, and then the lower page folding plate of the bottom device 53 of the carton head and the upper page folding plate of the upper page folding assembly 51 of the carton head fold and hold the lower page and the upper page of the carton head of the carton as the outer pages;

[0205] Sealing step: After the carton is folded, the lifting push plate 613 of the carton pushing device 61 rises, and the lifting push plate 613 is driven by the carton pushing drive assembly 611 to push the carton towards the carton outlet 12. The carton enters between the pressing rod assemblies 641 of the carton head pressing device 64 and the carton tail pressing device 65 to prevent the two side pages from opening by themselves and affecting the conveying of the carton. After entering the area of the pressing rod assembly 641 for a certain distance, it will pass between the first roller assemblies 642 of the carton head pressing device 64 and the carton tail pressing device 65. The first unpowered rollers arranged linearly on both sides cooperate with the carton pushing device 61 for clamping and conveying. Then, the carton is sealed with adhesive tape by two sealing glue assemblies 621 and sent out through the carton outlet 12.

[0206] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
