Description

Technical Field

[0001] The present invention relates to the field of packaging equipment, and particularly to an electronic atomizer packaging box. Background Art

[0002] At present, there are basically two modes for the automatic box folding machine of the electronic atomizer packaging box to fold the box. One is to pre-stick the glue on each side of the packaging box, and then set folding motion components at multiple directions of the work station to drive the multiple sides of the packaging box to fold, so as to complete the folding and sticking of multiple sides of the packaging box in a short time, and then perform pipeline feeding and complete the ear insertion; the other is to pre-stick the middle part of the packaging box and press it into a flat body that opens into a square column, open the flat body of the packaging box by the suction opening method, and then complete the ear insertion after pipeline feeding. In the first method, only one packaging box can be folded at each work station. If the efficiency needs to be improved, the folding motion components need to be increased, and there is a relatively high cost for improving the production efficiency. In the second method, all steps need to be completed on two machines, and the production efficiency is restricted. Moreover, the packaging box with ear insertion at both ends has slightly poor stability during transportation due to the lack of glue sticking.

[0003] The technical problem to be solved by this application is to optimize the folding and gluing method of small packaging boxes to improve production efficiency and ensure the stability of the packaging boxes. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an automatic box folding and loading system.

[0005] The technical solution adopted by the present invention is: an automatic box folding and loading system, including a conveyor belt, a box loading synchronous belt, and a material feeding synchronous belt. The conveyor belt and the box loading synchronous belt are respectively provided with carriers for placing the packaging boxes. The inner width of the carrier is the same as the width of the packaging box. The conveyor belt, the box loading synchronous belt, and the material feeding synchronous belt are arranged in parallel. The conveyor belt is provided with a rear end surface glue spraying component, a rear end surface folding component, a side ear glue spraying component, and a box pushing and folding component that the carrier passes through in sequence. The box pushing and folding component pushes the packaging box from the conveyor belt to the box loading synchronous belt. The material feeding synchronous belt is provided with a material pushing component, and the material pushing component pushes the materials on the material feeding synchronous belt to the box loading synchronous belt. The box loading synchronous belt is provided with a front end surface guiding component and an ear inserting component that the carrier passes through in sequence.

[0006] The packaging box enters the vehicle. Due to the width limitation of the vehicle, both sides of the packaging box will be folded after entering the vehicle. Since the packaging box needs to be folded and then loaded with materials, it needs to go through the folding and gluing process on the conveyor belt and then enter the box loading synchronous belt for the loading process. Since the conveyor belt, the box loading synchronous belt, and the material feeding synchronous belt are arranged in parallel, the packaging box can enter the box loading synchronous belt from the conveyor belt through the box pushing and folding assembly. The material pushing assembly pushes the materials on the material feeding synchronous belt onto the box loading synchronous belt. The packaging box finally completes the ear inserting process on the box loading synchronous belt. The entire system completes the packaging box from the open state, folding and gluing, loading to the final overall closing of the box. Since both the folding and gluing and the box loading are in-line operations, and the folding steps of the packaging box are optimized, the production efficiency of the folding and gluing of the packaging box is greatly improved.

[0007] In some embodiments, it includes a feeding module and a guiding and folding assembly. The feeding module drives the packaging box through the guiding and folding assembly into the vehicle. The guiding and folding assembly includes guiding and folding rods. Every two guiding and folding rods form a group, and the distance between the guiding and folding rods in the same group is the same as the width of the vehicle. The guiding and folding rods are fixedly suspended above the conveyor belt. The feeding module drives the packaging box to pass through the guiding and folding assembly first and then enter the vehicle. The guiding and folding rods can pre-fold both sides of the packaging box in advance to facilitate the packaging box to maintain the folded state after entering the vehicle.

[0008] In some embodiments, the rear-end surface gluing assembly includes a rear-end surface dotting machine, and the rear-end surface folding assembly includes a guiding rear-end surface rod. One end of the guiding rear-end surface rod close to the rear-end surface gluing assembly is inclined. The rear-end surface dotting machine is arranged above one end of the guiding rear-end surface rod close to the rear-end surface gluing assembly. When the rear-end surface of the packaging box is lifted by the guiding rear-end surface rod, the rear-end surface of the packaging box is dotted with glue. The whole process is smooth and does not require an additional driving element to drive the rear-end surface dotting machine to work.

[0009] In some embodiments, the rear-end surface folding assembly includes a rear-end surface pressing head, a rear-end surface pressing driving element, a rear-end surface transverse pressing head, and a rear-end surface transverse pressing driving element. The rear-end surface pressing driving element drives the rear-end surface pressing head to approach or move away from the packaging box, and the rear-end surface transverse pressing driving element drives the rear-end surface transverse pressing head to move towards the vehicle direction and press the rear-end surface of the packaging box against the vehicle. The cooperation of the rear-end surface pressing head and the rear-end surface transverse pressing head completes the folding of the rear-end surface of the packaging box.

[0010] In some embodiments, a box supporting assembly is provided between the rear end face folding assembly and the side ear gluing assembly. A vertically arranged guiding plate is fixedly provided on one side of the conveyor belt. The box supporting assembly includes a box supporting driving element and a box supporting die. The guiding plate and the box supporting assembly are respectively arranged on both sides of the conveyor belt. The width of the box supporting die is the same as the width of the packaging box. The box supporting driving element drives the box supporting die to move towards the carrier and presses one end of the packaging box against the guiding plate. The box supporting assembly is to strengthen the folding marks inside the packaging box and adjust the position of the packaging box in the carrier.

[0011] In some embodiments, the side ear gluing assembly includes a side ear folding member and a side ear folding driving element. The side ear folding driving element is suspended above the conveyor belt. The output end of the side ear folding driving element is fixedly connected to the side ear folding member. The side ear folding member includes a third folding section and a fourth folding section. The angle between the third folding section and the fourth folding section is a right angle. The fourth folding section is closer to the carrier than the third folding section. The side ear folding driving element drives the side ear folding member close to the packaging box. The fourth folding section flattens the side ear of the packaging box, and the third folding section presses the side ear of the packaging box flat.

[0012] In some embodiments, the fixed end of the side ear folding driving element is connected to one side of the conveyor belt through a folding connecting plate and a folding connecting seat. An arc-shaped hole is provided on the folding connecting plate. The folding connecting plate is pressed tightly on the folding connecting seat through the cooperation of screws and the arc-shaped hole. The side ear folding member includes a second folding section. The angle between the second folding section and the third folding section is an obtuse angle. The third folding section is closer to the carrier than the second folding section. Due to the setting of the arc-shaped hole, the second folding section, the third folding section and the fourth folding section cooperate to complete the process of pushing and flattening the side ears of different packaging boxes, so as to adapt to the pushing and flattening operations of the side ears on different packaging boxes.

[0013] In some embodiments, the side ear gluing assembly includes a separating rod. The separating guide rod guides the packaging box to the side of the separating rod away from the conveyor belt. The bottom end of the separating rod is higher than the packaging box. The box pushing and folding assembly includes a box pushing structure and a folding end face structure. The folding end face structure includes a folding end face rod. The box pushing structure pushes the packaging box through the separating rod and into the lower part of the folding end face rod. The box pushing structure pushes the packaging box through the separating rod, and the front face of the packaging box is immediately pressed down by the separating rod. The folding end face rod presses the front face of the packaging box flat.

[0014] In some embodiments, the box pushing structure includes a front box pushing block, a front box pushing driving element, a rear material supporting and sucking block, and a rear material supporting driving element. The output end of the front box pushing driving element is connected to the front box pushing block, and the output end of the rear material supporting driving element is connected to the rear material supporting and sucking block. The front box pushing block and the rear material supporting and sucking block are respectively arranged on opposite sides of the folding end face structure. An air suction hole is provided on the side of the rear material supporting and sucking block facing the folding end face structure. The front box pushing block and the rear material supporting and sucking block jointly complete the movement of the packaging box between the conveyor belt and the box loading synchronous belt. Pushing and sucking can retain the states of the folded faces of the packaging box, and the pushing action is completed separately for the front box pushing block and the rear material supporting and sucking block, reducing the respective movement routes of the front box pushing block and the rear material supporting and sucking block and improving work efficiency.

[0015] In some embodiments, the material pushing assembly includes a material pushing driving element, a material pushing block, and a horn-shaped guiding port. The horn-shaped guiding port is arranged between the material conveying synchronous belt and the box loading synchronous belt. The larger opening of the horn-shaped guiding port faces the material conveying synchronous belt, the smaller opening faces the box loading synchronous belt, and the size of the smaller opening is consistent with the size of the front end face of the packaging box. The material pushing driving element drives the material pushing block to enter the horn-shaped guiding port through the material conveying synchronous belt. The horn-shaped guiding port ensures that the material can be smoothly pushed by the material pushing block into the packaging box on the box loading synchronous belt.

[0016] The beneficial effects of the present invention are as follows:

[0017] In this automatic folding and box loading system, by arranging the conveyor belt, the box loading synchronous belt, and the material conveying synchronous belt in parallel, the packaging box can enter the box loading synchronous belt from the conveyor belt through the box pushing and folding assembly, and the material pushing assembly pushes the material on the material conveying synchronous belt towards the box loading synchronous belt. The whole system completes the packaging box from the original open state, to folding and gluing, then to loading, and finally to closing the box as a whole. Since folding and gluing and box loading are all in-line operations, the overall folding steps of the packaging box are optimized, and the production efficiency of folding and gluing the packaging box is greatly improved.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 The present invention provides a technical solution: an automatic box folding and loading system, including a silo module 1, a loading module 2, a transport module 3, a box folding module 4 and a box loading module 5. This embodiment completes the entire process of folding and gluing the packaging box to form a feedable state and then feeding the material to complete the box loading process. The packaging box is combined with the plug-in ear. The packaging box is combined with the front face 01, the bottom face 02, the left side face 03, the right side face 04, two front ears 05, two rear ears 06, two side ears 07, the front face 08, the rear face 09 and the front plug-in ear.

[0035] See also Figure 2, the silo module 1 includes a storage table 11, a storage rack 12, a material taking component 13 and a moving component 14. The storage rack 12 is vertically and fixedly arranged on the storage table 11. The packaging boxes are vertically stacked on the storage rack 12. The storage table 11 is provided with a number of material discharging openings and supporting plates corresponding to the storage rack 12. The size of the material discharging opening is larger than that of the packaging box. The supporting plate is fixedly connected to the storage table 11 and arranged at the material discharging opening. Two supporting plates are arranged at the material discharging opening, and the distance between the two supporting plates is smaller than the width of the packaging box. The packaging boxes are stacked on the storage rack 12, and the packaging box at the bottom is arranged to abut against the surface of the supporting plate. Since the distance between the two supporting plates is smaller than the width of the packaging box, the packaging box will not fall off by itself. The material taking component 13 takes out the packaging box from the material discharging opening. The packaging box can be taken out when its two sides are slightly deformed. The material taking component 13 includes a material taking table 131, material taking suction cups and a material taking plate 133. The material taking table 131 is provided with a number of material taking suction cups. The material taking plate 133 is provided with a number of material suction openings communicated with the material taking suction cups. The suction heads of the material taking suction cups are communicated with the material suction openings. The moving component 14 includes a moving track 141, a moving table 142, a moving driving element 143, a moving lifting element 144 and a moving connecting rod. The moving driving element 143 is a motor, and the moving lifting element 144 is a cylinder. The moving track 141 is fixedly arranged under the storage table 11. The fixed end of the moving lifting element 144 is fixedly connected to the moving table 142, and the output end is fixedly connected to the moving connecting rod. The moving driving element 143 drives the moving table 142 to move along the moving track 141. A number of groups of material taking components 13 are arranged on the moving connecting rod. The moving driving element 143 drives the material taking component 13 to move from a preset position to the material discharging opening. The moving lifting element 144 drives the material taking component 13 to rise. The material taking suction cups suck the bottom of the packaging box on the storage through groove. The moving lifting element 144 drives the material taking component 13 to descend. The moving driving element 143 drives the material taking component 13 to leave the material discharging opening and return to the preset position. The preset position of the material taking component 13 is to stay on one side of the storage table 11.

[0036] Please refer to Figure 2, the loading module 2 includes a loading outer frame 21, a loading track 22, a loading moving table 23142, a loading driving element, a loading lifting element 25 and a loading pressing block 26. The loading track 22 is fixedly arranged on the loading outer frame 21 and is located above the moving assembly 14. The loading driving element is a motor, and the loading lifting element 25 is a cylinder. The loading driving element drives the loading moving table 23142 to move on the loading track 22. The fixed end of the loading lifting element 25 is fixedly connected to the loading moving table 23142, and the output end is fixedly connected to a plurality of loading pressing blocks 26 through a loading connecting frame. The loading lifting element 25 drives the loading pressing blocks 26 to lift and limit. A plurality of loading suction cups are arranged at the bottom of the loading pressing block 26, and the suction heads of the loading suction cups face downward. The loading driving element drives the loading pressing block 26 to move along the loading track 22 above the material taking plate 133. The loading lifting element 25 drives the loading pressing block 26 to move downward. The loading suction cups on the loading pressing block 26 suck the packaging boxes on the material taking plate 133. After sucking, the loading driving element and the loading lifting element 25 cooperate to drive the loading pressing block 26 back to the preset position. The preset position of the loading pressing block 26 is to stay above the transportation module 3.

[0037] Please refer to Figure 1 and Figure 3 , the transportation module 3 includes a conveying frame, a conveyor belt 32, a conveying driving assembly, a front support plate 34 and a rear support plate 35. The conveying driving assembly is a combination of a motor and a reducer. The conveying driving assembly drives the conveyor belt 32 to rotate and limit on the conveying frame. A plurality of carriers 10 are arranged on the surface of the conveyor belt 32. The carrier 10 is composed of two baffles arranged in the normal direction of the packaging box conveying direction. The width between the two baffles of the same carrier 10 is the same as the width of the bottom surface 02 of the packaging box. The length of the carrier 10 is not greater than the length of the bottom surface 02 of the packaging box. The height of the carrier 10 is lower than the final height of the packaging box. The packaging box is placed in the carrier 10, and the width of the loading pressing block 26 is smaller than the width between the two baffles of the same carrier 10. The conveyor belt 32 is arranged between the front support plate 34 and the rear support plate 35. The front support plate 34 and the rear support plate 35 are responsible for supporting the front and rear ends of the bottom surface 02 of the packaging box. The loading driving element drives the loading pressing block 26 to move above the carrier 10, and the loading lifting element 25 and the loading suction cups cooperate to place the packaging box into the carrier 10. Due to the reason that the width of the carrier 10 is the same as the width of the bottom surface 02 of the packaging box, the left side surface 03 and the right side surface 04 of the packaging box will fold upward along the baffles, and the front ears 05, the rear ears 06, the front end surface 08 and the rear end surface 09 are all exposed outside the carrier 10. The part of the packaging box exposed outside the carrier 10 is mainly supported by the front support plate 34 and the rear support plate 35.

[0038] Please refer to Figure 3, the folding box module 4 includes a guiding and folding component 41, a rear end surface glue spraying component 42, a rear end surface folding component 43, a box supporting component 44, a side ear glue spraying component 45 and a box pushing and folding component 46. The transportation module 3 drives the packaging box to pass through the guiding and folding component 41, the rear end surface glue spraying component 42, the rear end surface folding component 43 and the side ear glue spraying component 45 in sequence. For the schematic diagram of the folding effect of the folding box module 4, please refer to Figure 14 .

[0039] Please refer to Figure 3 , the guiding and folding component 41 is arranged on one side of the feeding module 2 and above the transportation module 3. The guiding and folding component 41 includes a front connecting rod 411, a rear connecting rod 412, guiding and folding rods 413, a front cross fixing frame 414 and a rear cross fixing frame 415. The front connecting rod 411 is arranged on the front support plate 34 through the front cross fixing frame 414, and the rear connecting rod 412 is arranged on the rear support plate 35 through the rear cross fixing frame 415. Both ends of several guiding and folding rods 413 are fixedly connected to the front connecting rod 411 and the rear connecting rod 412 respectively through corresponding connecting blocks. Every two guiding and folding rods 413 form a group, and the distance between the guiding and folding rods 413 in the same group is the same as the width of the carrier 10. The guiding and folding rods 413 are fixedly suspended above the conveyor belt 32. The distance between the guiding and folding rods 413 can be adjusted on the front connecting rod 411 and the rear connecting rod 412. The front cross fixing frame 414 is fixedly connected to the front support plate 34, and the rear cross fixing frame 415 is fixedly connected to the rear support plate 35. The front connecting rod 411 adjusts its height on the front cross fixing frame 414, and the rear connecting rod 412 adjusts its height on the rear cross fixing frame 415. The position of the guiding and folding rods 413 is to cooperate with the action of the feeding pressing block 26 entering the carrier 10. One group of guiding and folding rods 413 corresponds to the feeding operation of one feeding pressing block 26. The feeding pressing block 26 drives the packaging box to move towards the carrier 10. When passing through the guiding and folding rods 413, the two guiding and folding rods 413 will guide the left side surface 03 and the right side surface 04 of the packaging box to tilt upwards, facilitating the feeding pressing block 26 to place the packaging box in the carrier 10. After the packaging box enters the carrier 10, the left side surface 03 and the right side surface 04 are respectively folded and attached to the baffle, and at the same time, the front ear 05 and the rear ear 06 stand up along with the left side surface 03 and the right side surface 04.

[0040] Please refer to Figure 3 and Figure 4, the rear end surface glue spraying assembly 42 includes an ear guiding glue spraying seat 421, a page pressing plate 422, an ear punching structure 423, an ear pressing rod 424, and a rear end surface glue dispensing structure 425. The purpose of the rear end surface glue spraying assembly 42 is to respectively guide the two rear ears 06 to form a folding relationship with the left side surface 03 or the right side surface 04 and perform a glue spraying process on the rear ears 06. The ear guiding glue spraying seat 421 is arranged above the rear support plate 35 in a suspended manner. The page pressing plate 422 is arranged between the ear guiding glue spraying seat 421 and the rear support plate 35. A gap allowing the front surface 01 of the packaging box to pass through is provided between the page pressing plate 422 and the rear support plate 35. A pressing material inclined plate is fixedly provided at one end of the page pressing plate 422 close to the guiding folding assembly 41. The distance between the pressing material inclined plate and the rear support plate 35 gradually decreases from the guiding folding assembly 41 towards the page pressing plate 422. The pressing material inclined plate is for the front surface 01 of the packaging box to smoothly enter the gap between the page pressing plate 422 and the rear support plate 35. The purpose of setting the page pressing plate 422 is to prevent the front surface 01 of the packaging box from affecting the folding and glue dispensing processes of the rear ears 06 of the packaging box by the subsequent components.

[0041] The ear pressing rod 424 is arranged on one side of the conveyor belt 32 close to the rear support plate 35. A gap allowing the rear ear 06 to pass through is provided between the ear pressing rod 424 and the carrier 10. A guiding ear inclined surface is provided at one end of the ear pressing rod 424 close to the guiding folding assembly 41. The function of setting the guiding ear inclined surface is to gradually change the folding angle between the rear ear 06 on the packaging box far from the guiding folding assembly 41 and the right side surface 04. The overall function of the ear pressing rod 424 is to maintain the folding angle between the rear ear 06 and the left side surface 03 or the right side surface 04.

[0042] The ear - punching structure 423 is arranged above the page - pressing plate 422 and on the side of the ear - pressing rod 424 close to the guiding and folding assembly 41. The ear - punching structure 423 includes an ear - punching rotating seat 4231, an ear - punching driving element 4232, an ear - punching rod 4233, and an ear - punching connecting piece 4234. The ear - punching rod 4233 is arranged in an "L" shape. The ear - punching driving element 4232 is an oil cylinder, an electric cylinder, or a pneumatic cylinder with a linear - motion output end. The fixed end of the ear - punching driving element 4232 is rotation - limited on the ear - guiding glue - spraying seat 421, and the output end is rotation - limitedly connected to the ear - punching connecting piece 4234. The ear - punching connecting piece 4234 is fixedly sleeved on the ear - punching rotating seat 4231 and is eccentrically arranged. The ear - punching rotating seat 4231 is rotation - limited on the ear - guiding glue - spraying seat 421, and the ear - punching rod 4233 is fixedly connected to the outer wall of the ear - punching rotating seat 4231. When the ear - punching driving element 4232 outputs, it drives the ear - punching rotating seat 4231 to rotate, thereby driving the ear - punching rod 4233 to perform an arc - shaped motion within a certain range. One of the moving endpoints of the ear - punching rod 4233 is the end of the ear - pressing rod 424 close to the guiding and folding assembly 41. The purpose of the ear - punching rod 4233 is to fold the rear ear 06 on the side close to the guiding and folding assembly 41.

[0045] The rear-end face folding assembly 43 includes a guide rear-end face rod 431 and a rear-end face folding structure. On one side of the rear support plate 35 close to the conveyor belt 32, there is a guide rear-end face hole which is an elongated hole and its length direction is consistent with the axial direction of the conveyor belt 32. The guide rear-end face hole is arranged below the rear-end face dispensing structure 425. The guide rear-end face rod 431 is suspended above the guide rear-end face hole. One end of the guide rear-end face rod 431 close to the rear-end face dispensing structure 425 is inclined and its lowest end is arranged at a position lower than the page pressing plate 422. The other end of the guide rear-end face rod 431 is arranged at a position higher than the rear support plate 35, aiming to gradually guide the rear-end face 09 of the packaging box to lift upward and form an angle with the bottom surface 02 of the packaging box. The rear-end face dispensing structure 425 is arranged at one end of the guide rear-end face rod 431 close to the page pressing plate 422. The rear-end face dispenser 4251 is arranged above one end of the guide rear-end face rod 431 close to the rear-end face dispensing structure 425. When the rear-end face 09 is lifted, the rear-end face dispenser 4251 simultaneously performs a dispensing operation on the rear-end face 09.

[0046] Please refer to Figure 3 and Figure 5 , the rear-end face folding structure includes a rear-end face lower pressing head 432, a rear-end face lower pressing driving element 433, a rear-end face transverse pressing head 434 and a rear-end face transverse pressing driving element 435. Both the rear-end face lower pressing driving element 433 and the rear-end face transverse pressing driving element 435 are oil cylinders, electric cylinders or air cylinders with linear motion at the output end. The rear-end face lower pressing driving element 433 drives the rear-end face lower pressing head 432 to move up and down. The rear-end face lower pressing head 432 is suspended above one end of the carrier 10 close to the rear support plate 35. The rear-end face transverse pressing driving element 435 drives the rear-end face transverse pressing head 434 to move closer to or away from the carrier 10. The rear-end face transverse pressing head 434 and the rear-end face transverse pressing driving element 435 are arranged on the rear support plate 35. The rear-end face lower pressing driving element 433 drives the rear-end face lower pressing head 432 to move closer to or away from the bottom surface 02 of the packaging box. The height of the rear-end face transverse pressing head 434 is lower than the height of the guide rear-end face rod 431 from the rear support plate 35. The rear-end face lower pressing head 432 can pass through the space between the guide rear-end face rod 431 and the rear support plate 35 to reach the carrier 10. The fixed end of the rear-end face transverse pressing element is fixedly connected to the rear support plate 35. The rear-end face lower pressing head 432 presses down. At this time, the rear-end face lower pressing head 432 stays on the surface of the bottom surface 02 of the packaging box and on one side of the rear ear 06. The rear-end face transverse pressing head 434 moves towards the carrier 10 and presses the rear-end face towards the carrier 10. At this time, due to the drive of the rear-end face transverse pressing head 434, the rear-end face is pressed towards the rear ear 06. The side of the rear-end face close to the rear ear 06 has been dispensed. The rear-end face lower pressing head 432 and the rear-end face transverse pressing head 434 jointly clamp the rear ear 06 and the rear-end face, and finally make the rear-end face 09 adhesively connected to the rear ear 06.

[0047] In order to ensure that the rear end face 09 and the front face 01 remain vertical in subsequent processes, a positioning plate 36 is fixedly provided on one side of the rear support plate 35 close to the carrier 10. The positioning plate 36 is vertically and fixedly arranged on the rear support plate 35, and there is a gap between the positioning plate 36 and the carrier 10 that allows the rear end face 09 and the front face 01 to pass through. A positioning guiding inclined surface is fixedly provided at one end of the positioning plate 36 close to the rear end face folding structure. The distance between the positioning guiding inclined surface and the carrier 10 gradually decreases from the rear end face folding structure towards the positioning plate 36 to facilitate the gradual guiding of the front face 01 of the packaging box. The positioning plate 36 can also be used to support the front face 01 to prevent the front face 01 from falling down and affecting subsequent processes.

[0048] Please refer to Figure 3 As shown in the figure, the box supporting assembly 44 is arranged on the front support plate 34. The box supporting assembly 44 includes a box supporting driving element 441 and a box supporting die 442. The box supporting driving element 441 is an oil cylinder, an electric cylinder, or a cylinder with a linear motion output end. A positioning plate 36 is arranged on the extension line of the output direction of the box supporting driving element 441. The fixed end of the box supporting driving element 441 is fixedly arranged on the front support plate 34, and the output end is fixedly connected to the box supporting die 442. The width of the box supporting die 442 is the same as the width of the bottom surface 02. One end of the box supporting die 442 close to the carrier 10 is an end face setting. The box supporting driving element 441 drives the box supporting die 442 to move in and out of the carrier 10. When the carrier 10 stays on one side of the box supporting die 442, the box supporting driving element 441 drives the box supporting die 442 into the carrier 10 and cooperates with the carrier 10 and the positioning plate 36 to shape the folded faces of the packaging box in the carrier 10, including shaping the folding angles between the left side face 03, the right side face 04, and the bottom surface 02, shaping the folding angles between the rear end face 09, the rear ear 06, and the bottom surface 02, and also fixing the pasting relationship between the rear end face 09 and the rear ear 06. Since there is no folding and shaping step for the left side face 03 and the right side face 04 before this step, the box supporting die 442 can help the left side face 03 and the right side face 04 respectively form deeper folding marks with the bottom surface 02. Similarly, the box supporting die 442 can help the rear end face 09 and the rear ear 06 respectively form deeper folding marks with the bottom surface 02, and the box supporting die 442 can also adjust the position of the packaging box in the carrier 10.

[0049] To prevent the box supporting die 442 from accidentally touching the front end face 08 during movement, a pressing end face plate 37 is provided on one side of the front support plate 34 close to the carrier 10. The pressing end face plate 37 is suspended on the front support plate 34, and there is a gap between the pressing end face plate 37 and the front support plate 34 that allows the front end face 08 and the insertion ear to pass through.

A fixed connecting separating guide rod is provided at one end of the separating rod 451 close to the orientation plate 36. The distance between the separating guide rod and the carrier 10 gradually increases from the orientation plate 36 to the direction of the separating rod 451. The front side 01 of the packaging box enters the gap between the separating rod 451 and the orientation plate 36 through the guiding of the separating guide rod, so that the front side 01 of the packaging box is on the side of the separating rod 451 away from the carrier 10.

[0051] There are two side ear folding members 453 and corresponding side ear folding driving elements 454, which respectively fold the side ears 07 on both sides of the packaging box. Two groups of side ear glue spraying machines 452 and side ear folding driving elements 454 are respectively arranged on both sides of the corresponding positions of the carrier 10. The side ear folding driving element 454 is an oil cylinder, an electric cylinder or a cylinder with a linear motion output end. The side ear folding driving element 454 is suspended above the conveyor belt 32. The output end of the side ear folding driving element 454 is fixedly connected to the side ear folding member 453. The side ear folding member 453 is composed of four parts, including a first fixed section 4531, a second folding section 4532, a third folding section 4533 and a fourth folding section 4534 arranged in sequence. The included angle between the first fixed section 4531 and the second folding section 4532 is a right angle. The included angle between the second folding section 4532 and the third folding section 4533 is an obtuse angle. The included angle between the third folding section 4533 and the fourth folding section 4534 is a right angle. The first fixed section 4531 is fixedly connected to the output end of the side ear folding driving element 454. The fourth folding section 4534 is close to the carrier 10. The third folding section 4533 and the fourth folding section 4534 can cooperate to complete the operation of first pushing and then flattening the side ear 07, on the one hand folding the side ear 07, and on the other hand facilitating the side ear glue spraying machine 452 to spray glue on the side ear 07.

[0052] The fixed end of the side ear folding driving element 454 is connected to the front support plate 34 through a folding connecting plate 463 and a folding connecting seat 464. An arc-shaped hole is provided on the folding connecting plate 463. The folding connecting plate 463 is connected to the folding connecting seat 464 by screwing through the arc-shaped hole and pressing it on the folding connecting seat 464. By adjusting the connection between different positions of the arc-shaped hole and the folding connecting seat 464, the inclined angle of the side ear folding driving element 454 above the conveyor belt 32 is different. Correspondingly, the second folding section 4532, the third folding section 4533 and the fourth folding section 4534 cooperate to complete the process of pushing and flattening the side ear 07 of different packaging boxes, so as to adapt to the pushing and flattening operations of the side ear 07 on different packaging boxes.

One end of the folding end face rod 462 close to the partition rod 451 is an L-shaped rod with an inclined setting, and the end away from the partition rod 451 is a straight rod. The height of the straight rod from the front support plate 34 is the same as the height of the finally formed packaging box. When the front side 01 of the packaging box passes through the L-shaped rod, since the L-shaped rod presses the upward side of the front side 01, the front side 01 will be gradually tilted downward. When the front side 01 passes through the straight rod, it is completely in a folded state and the front side 01 is adhesively connected to the side ear 07. The folding end face pressing wheel 461 is arranged at the end of the straight rod away from the partition rod 451. The height of the bottom end of the folding end face pressing wheel 461 from the front support plate 34 is the same as the height of the finally formed packaging box. The position of the folding end face pressing wheel 461 is correspondingly set with the positions of the left side 03 and the right side 04 of the packaging box. The height of the folding end face structure can be adjusted as a whole. The packaging box with good spot glue in the carrier 10 is pushed from the carrier 10 towards the folding end face structure through the box pushing structure. When the packaging box passes through the folding end face structure, the front side 01 of the packaging box will be gradually folded downward by the folding end face rod 462. The folding end face pressing wheel 461 strengthens the folding mark between the front side 01 and the rear end face 09. At the same time, the folding end face pressing wheel 461 presses the front side 01 to be adhesively connected to the left side 03 and the right side 04.

The pusher component 53 includes a pusher driving element 531, a pusher block 532, and a horn-shaped guiding port 533. The pusher driving element 531 is a servo motor guide rail. The output end of the pusher driving element 531 is connected to the pusher block 532. The purpose of the pusher component 53 is to transfer the materials in the material trough to the carrier 10 of the box loading synchronous belt 511 and into the box. The horn-shaped guiding port 533 is arranged between the material conveying synchronous belt 521 and the box loading synchronous belt 511. The larger opening of the horn-shaped guiding port 533 faces the material conveying synchronous belt 521, the smaller opening faces the box loading synchronous belt 511, and the size of the smaller opening is the same as the size of the front end face 08 of the packaging box. Since the materials are placed by hand, the specific positions and placement directions of the materials in the material trough are different. The purpose of setting the horn-shaped guiding port 533 is to enable all the materials to be pushed by the pusher component 53 to the box loading synchronous belt 511. Even if the materials in the material trough and the packaging box in the carrier 10 on the box loading synchronous belt 511 are not in the same straight line, when the pusher block 532 pushes the materials, the materials can gradually be in the same straight line with the packaging box in the carrier 10 along the inner wall of the horn-shaped guiding port 533, so as to ensure that the materials can smoothly enter the packaging box to complete the box loading process.

[0062] To prevent the materials from being placed vertically in the material trough, which is not conducive to the pusher component 53 pushing the materials, a pressing plate is provided on the material conveying frame. The pressing plate is suspended on the material conveying synchronous belt 521. When the materials pass through the pressing plate in the vertical direction, the pressing plate will press them into the material trough.
