The sizing mechanism includes a plurality of feeding channels for receiving products from the feeding mechanism, causing the products to be divided into several columns that move correspondingly within each feeding channel. The grouping mechanism is used to receive products from each column, and includes grouping rods for separating products at preset positions in the product queue to form a grouped array of products. The feeding mechanism is used to receive the grouped array of products, and includes feeding rods that act on the grouped array of products, causing each product to move close to each other to the receiving station.

[0011] According to a first aspect embodiment of the present invention, the paper packaging machine includes a sorting mechanism comprising a second conveying mechanism, a gantry frame, and a plurality of partition plates disposed on the gantry frame.

The transmission mechanism includes a plurality of mounting members and track assemblies disposed at both ends of the mounting members. The bottom end of each mounting member is hinged to the third conveying mechanism. Each grouping rod is fixedly connected to the mounting member. The third conveying mechanism is used to drive the mounting members to rotate. The track assemblies guide the swing direction of each mounting member, so that each mounting member intermittently enters and leaves the product queue at a preset swing direction and preset speed.

The rear folding member and the front folding member are arranged sequentially along the transport direction of the first conveying mechanism. The front folding member includes two sets of relatively movable first baffles and second baffles. The rear folding member includes two sets of relatively fixed third baffles and fourth baffles. The first baffles and the third baffles have two working conditions: standing up and tilting outwards. When the first baffles and the third baffles are standing up, they can respectively stand up the first adhesive sheets on both sides. When the first baffles and the third baffles are tilted outwards, they can open up the inward folding space of each side page. The second baffle is fixedly mounted on the outside of the first baffle. The fourth baffle is fixedly connected to the outside of the third baffle and moves synchronously with the third baffle. The second baffles and the fourth baffles are used to cooperate with the paper guide assembly to guide each side page on both sides to fold inwards.

The second folding and forming assembly includes a rotary fourth conveying mechanism and a plurality of buffer members and a plurality of pressure plate assemblies disposed on the fourth conveying mechanism. The pressure plate assembly includes a first pressure plate and a second pressure plate disposed at intervals. Each of the buffer members is disposed between the first pressure plate and the second pressure plate so that the buffer member can softly contact the top page. When each of the first pressure plate and the second pressure plate rotates from the upper side to the lower side of the fourth conveying mechanism, the second adhesive sheet is folded inward by swinging down.

[0034] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1-5 The paper packaging machine of the first aspect of the present invention is applied to a product packaging production line. The paper packaging machine includes a feeding mechanism 10, a separating mechanism 20, a paper feeding mechanism 30, and a packaging forming mechanism 40.

[0036] The feeding mechanism 10 is used to transport products. It is understood that the feeding mechanism 10 includes a feeding area and baffles on both sides of the feeding area. A conveyor chain plate for conveying is provided on the feeding area. It is understood that, in order to better transport products, the baffles on both sides can be set as flared openings to guide the products and allow the products to be better fed into the separating mechanism 20. Furthermore, a flexible buffer can be set between the feeding mechanism 10 and the separating mechanism 20 to avoid accidents caused by collisions and squeezing during the transport process.

[0037] The separating mechanism 20 is used to divide the products into batches, receive the products from the feeding mechanism 10, and output a preset number of products in an array. It can be understood that the products conveyed from the feeding mechanism 10 are random and disorderly. The role of the separating mechanism 20 is to uniformly receive the products from the feeding mechanism 10 and guide the products to be transported in sequence and batch. Finally, the output products can be arranged into several rows and several columns. The specific number of rows and columns can correspond to the size of the cardboard 50. One array of products corresponds to one cardboard 50. After packaging, the products will fill the carton.

[0038] The paper feeding mechanism 30 is used to transport the cardboard 50 in an open state. It can be understood that the conventional cardboard 50 is in an open state and has certain creases. It can be turned into a carton by folding along the creases according to a preset folding method. The feeding mechanism 10 and the paper feeding mechanism 30 can achieve continuous and uninterrupted conveying to realize the connection between production and carton output.

[0039] The packaging forming mechanism 40 is used to pack cardboard 50, making the product into a carton. The packaging forming mechanism 40 includes a first conveying mechanism 41 and a forming module. The first conveying mechanism 41 has a receiving station 452 and a paper receiving station 451. The paper receiving station 451 is used to receive cardboard 50 from the paper feeding mechanism 30. The cardboard 50 received at the paper receiving station 451 is used to receive the product output from the separating mechanism 20 at the receiving station 452. The forming module is used to form the cardboard 50, so that the cardboard 50 packages the product. It can be understood that the packaging forming mechanism 40 receives the product from the feeding mechanism 10 and the cardboard 50 from the paper feeding mechanism 30 through the first conveying mechanism 41. The forming module is arranged along the conveying path of the first conveying mechanism 41, so that the cardboard 50 will automatically package the product and form a carton after being transported by the first conveying mechanism 41, realizing automated packaging forming. It should be noted that, in order to ensure a more reasonable spatial arrangement, the paper feeding mechanism 30 is positioned below the feeding mechanism 10, and the receiving station 452 is located directly above the paper receiving station 451. After receiving the cardboard 50, the paper receiving station 451 of the first conveying mechanism 41 positions and limits the cardboard 50. After confirming that the cardboard 50 is accurately positioned, it waits for the feeding mechanism 10 to convey the product onto the cardboard 50 of the first conveying mechanism 41, thus completing the action of placing the product on the cardboard 50.

[0040] The product is fed into the feeding mechanism 10, and the input product is grouped by the separating mechanism 20 to arrange it into an array and quantity suitable for packaging. On the other hand, the cardboard 50 is fed into the paper feeding mechanism 30 and merged with the product in the packaging forming mechanism 40. The packaging forming mechanism 40 forms the cardboard 50, so that the cardboard 50 packages the product and completes the packaging.

[0041] In some embodiments of the present invention, the separating mechanism 20 includes a sorting mechanism 21, a grouping mechanism 22, and a feeding mechanism 23. The sorting mechanism 21 includes a plurality of feeding channels for receiving products from the feeding mechanism 10, so that the products are divided into several columns and move correspondingly in each feeding channel. The grouping mechanism 22 is used to receive products from each column. The grouping mechanism 22 includes grouping rods for separating products at preset positions in the product queue to separate products into groups. The feeding mechanism 23 is used to receive products in groups. The feeding mechanism 23 includes feeding rods 231, which act on the products in groups to make each product move closely to the receiving station 452. Understandably, to ensure the speed of product input, the products input through the feeding mechanism 10 are not guided or arranged. However, to ensure the products can smoothly pass through subsequent workstations and mechanisms, they need to be arranged, separated, and aligned. For this purpose, a sorting mechanism 21 is set up to first divide the products into several columns for sequential transport. Then, a grouping mechanism 22 laterally separates the columns of products, with each separated array forming a group. Finally, a feeding mechanism 23 aligns each group of products, ensuring that each group can smoothly pass through subsequent workstations and cooperate with each mechanism. Understandably, the products input from the feeding mechanism 10 randomly enter each feeding channel. The number of feeding channels is set according to the specifications of the cardboard 50. The feeding channels guide the products, achieving the effect of arrangement. The lateral spacing between adjacent products output from each feeding channel is also determined. Understandably, by inserting grouping rods into the product queue and designing a certain speed difference between the product transport speed and the moving speed of the grouping rods, the grouping rods can act on the products to achieve separation. Similarly, by having the material-driving rod 231 move faster than the product transport speed, the material-driving rod 231 can move forward relative to the product queue, thereby accelerating the product from behind, reducing or eliminating the longitudinal gap between products, and achieving the material-driving effect.

[0042] In some embodiments of the present invention, the sorting mechanism 21 includes a second conveying mechanism, a gantry frame 211, and a plurality of partition plates 212 disposed on the gantry frame 211. The gantry frame 211 is arranged across the second conveying mechanism at intervals, and each partition plate 212 is adjustablely disposed on the gantry frame 211. Adjacent partition plates 212 form an adjustable-width feeding channel. It is understood that the gantry frame 211 serves as a mounting platform for the partition plates 212. Corresponding adjustable mounting positions are provided on the gantry frame 211, and the partition plates 212 can be adjusted according to the models and specifications of different products, thus broadening the scope of application. Furthermore, the laterally adjacent partition plates 212 form a feeding channel, and the longitudinally adjacent partition plates 212 are sequentially connected to extend the feeding channel. Corresponding movement direction adjustment designs can be made at the connection points, and corresponding flexible limiting components can also be provided at the connection points to ensure normal product transportation.

[0043] In some embodiments of the present invention, the grouping mechanism 22 includes a third conveying mechanism 221 and a transmission mechanism. The transmission mechanism includes multiple mounting members 223 and track assemblies 222 disposed at both ends of the mounting members 223. The bottom end of each mounting member 223 is hinged to the third conveying mechanism 221. Each grouping rod is fixedly connected to the mounting member 223. The third conveying mechanism 221 drives the mounting members 223 to rotate. The track assemblies 222 guide the swing direction of each mounting member 223, so that each mounting member intermittently enters and leaves the product queue at a preset swing direction and preset speed. By rotating the mounting members 223 through the third conveying mechanism 221, and simultaneously allowing the mounting members 223 to be adjusted to a certain extent at their hinged ends by the guidance of the track assemblies 222, the grouping rods disposed on the mounting members 223 are adjusted accordingly. This allows the grouping rods to extend into the material queue at a suitable swing direction to push the products into batches, and to leave the product queue at a suitable swing direction, achieving the effect of product batching with higher precision. It should be noted that, in order to further improve the guiding function, the track assembly 222 includes a main guide track 2221 and a secondary guide track 2222. The main guide track 2221 is located on the outer periphery of the secondary guide track 2222. At least two rollers 2231 are provided at both ends of the mounting member 223. Each roller 2231 is respectively located on the main guide track 2221 and the secondary guide track 2222, so that the swing direction of the mounting member 223 is simultaneously adjusted by the guidance of the main guide track 2221 and the secondary guide track 2222. This makes the design of the movement path, swing direction, and speed of the mounting member 223 simpler and more reasonable. It should be noted that the roller 2231, which is slidably mounted on the main guide rail 2221 and the secondary guide rail 2222, needs to have its axial degrees of freedom limited to prevent the roller 2231 from derailing. The roller 2231 can adjust the swing angle of the mounting member 223 by rotating, thereby adjusting the swing direction. This can be achieved by specifically designing the curvature of the main guide rail 2221 and the secondary guide rail 2222. In some embodiments, there is one roller 2231 on the main guide rail 2221 and two rollers 2231 on the secondary guide rail 2222. By adjusting the swing direction of the mounting member 223 with three rollers 2231, the resulting route design accuracy is higher, and the product sorting effect is better.

[0044] In some embodiments of the present invention, the feeding mechanism 23 includes a drive assembly and at least two feeding chains 232, each feeding chain 232 being disposed on both sides of the product queue. The drive assembly drives the feeding chains 232 to rotate, and feeding rods 231 are spaced apart between the feeding chains 232 on both sides, allowing each feeding rod 231 to enter and leave the product queue intermittently. It is understood that by using the feeding chains 232 as a transmission assembly, high-speed feeding is ensured to be stable and noiseless. The feeding chains 232 being disposed on both sides of the product queue allows each feeding rod 231 to cross over into the product queue, and its feeding effect is not affected by the number of upstream feeding channels. Furthermore, to prevent the material-driving rod 231 from pushing over the product, the position of the material-driving rod 231 acting on the product can be adjusted accordingly. The adjustment can be achieved by changing the height of the material-driving chain 232, or by setting up corresponding sensors to detect whether the product is being pushed over. When a malfunction occurs, the machine should be stopped in time, and the corresponding mechanism should be used to straighten the product. The material-driving mechanism 23 can also be equipped with protective structures such as guardrails, baffles and tracks.

[0045] In some embodiments of the present invention, the forming module includes a glue spraying mechanism 42, a forming component, and a paper guiding component 43. The cardboard 50 includes a top page 51, a first side page 52, a bottom page 53, and a second side page 54 that are sequentially adjacent to each other. The bottom page 53 is used to place the product. The bottom page 53 has a first adhesive sheet 531 on both sides. The top page 51 has a second adhesive sheet 511 on both sides. The first side page 52 and the second side page 54 each have a side page 55 on both sides. The second side page 54 has a third adhesive sheet 541 at one end. It can be understood that, with the bottom page 53 as the reference for the bottom of the carton, the first side page 52 is located on the back of the carton after folding, the top page 51 is located on the top of the carton, and the second side page 54 is located on the front of the carton. The two side pages 55 of the first side page 52 and the two side pages 55 of the second side page 54 form the left and right sides of the carton body by complementing each other on the same side. The bottom page 53 has a first adhesive piece 531 at both ends along its length, and the top page 51 has a second adhesive piece 511 at both ends along its length. The first adhesive piece 531 and the second adhesive piece 511 are used to fix the top page 55 to each side page for packaging. The third adhesive piece 541 at one end of the second side page 54 is attached and fixed to one end of the top page 51.

[0046] The forming component is used to fold the first adhesive sheet 531 and the second adhesive sheet 511. The paper guiding component 43 is used to guide the top page 51, the first side page 52, the second side page 54, and the third adhesive sheet 541 to preset positions. The glue spraying mechanism 42 is used to output adhesive material, so that each side page 55 is relatively fixed with the first adhesive sheet 531 and the second adhesive sheet 511, and the top page 51 is relatively fixed with the third adhesive sheet 541. It can be understood that the cardboard 50 containing the product is transported by the first conveying mechanism 41 along the path of the forming component, the paper guiding component 43, and the glue spraying mechanism 42, ultimately completing the packaging. Since the order of folding the various parts of the cardboard 50 is different, the arrangement and order of the forming component, the paper guiding component 43, and the glue spraying mechanism 42 can be adjusted accordingly. The paper guiding component 43 and the glue spraying mechanism 42 can also be set between the two stations of the forming component where the first adhesive sheet 531 and the second adhesive sheet 511 are folded, so that the packaging action design is more reasonable.

[0047] In some embodiments of the present invention, the forming assembly includes a first folding forming assembly 442 and a second folding forming assembly 441; the first folding forming assembly 442 is used to fold the first adhesive pieces 531 at both ends of the bottom page 53, and the second folding forming assembly 441 is used to fold the second adhesive pieces 511 at both ends of the top page 51. Along the transport direction of the first conveying mechanism 41, the first folding forming assembly 442, the paper guiding assembly 43, the glue spraying mechanism 42 and the second folding forming assembly 441 are arranged in sequence to realize packaging forming.

[0048] The first folding and forming assembly 442 is mounted on the first conveying mechanism 41. The first folding and forming assembly 442 includes a front folding member 4422 and a rear folding member 4421. The rear folding member 4421 and the front folding member 4422 are arranged sequentially along the transport direction of the first conveying mechanism 41. The front folding member 4422 includes two sets of relatively movable first baffles 44211 and second baffles 44212. The rear folding member 4421 includes two sets of relatively fixed third baffles 44221 and fourth baffles 44222. The first baffles 44211 and the third baffles 44221 have two opposing features: one that can be raised and the other that can be tilted outwards. In each working condition, when the first baffle 44211 and the third baffle 44221 are erected, they can respectively erect the first adhesive pieces 531 on both sides. When the first baffle 44211 and the third baffle 44221 are tilted outward, they can create inward folding space for each side panel 55. The second baffle 44212 is fixedly installed on the outside of the first baffle 44211, and the fourth baffle 44222 is fixedly connected to the outside of the third baffle 44221 and moves synchronously with the third baffle 44221. The second baffle 44212 and the fourth baffle 44222 are used to cooperate with the paper guide assembly 43 to guide each side panel 55 on both sides to fold inward. It can be understood that setting relatively independent front folding parts 4422 and rear folding parts 4421 on both sides of the carton can improve control accuracy and ensure that the packaging action logic is reasonable when the cardboard 50 is in the corresponding position. When the front side panel 55 in the carton is folded inward, the force component is in the opposite direction of the transport direction. Therefore, the packaging operation of the front folding piece 4422 requires higher precision and needs to be specifically designed. On the other hand, when the rear side panel 55 in the carton is folded inward, the force component is in the same direction as the transport direction. Therefore, the structural design of the rear folding piece 4421 does not require high precision. It should be noted that the two first baffles 44211 are respectively positioned on the front two side panels 55, and the two third baffles 44221 are respectively positioned on the rear two side panels 55, so that the first baffles 44211 and the third baffles 44221 can act simultaneously on each of the first adhesive sheets 531 and the two side panels 55. The first baffle 44211 and the third baffle 44221 are movably disposed on the first conveying mechanism 41, and each has at least two working conditions. The first working condition of the first baffle 44211 and the third baffle 44221 is used to position the first adhesive sheet 531 to ensure that the first conveying mechanism 41 can smoothly and reliably convey the cardboard 50 and facilitate the packing of the product. Subsequently, the first working condition can also be used to keep the first adhesive sheet 531 close to the side page 55 to ensure a firm connection.The second working state of the first baffle 44211 and the third baffle 44221 is used to unfold the first adhesive sheet 531 outward at a certain angle to prevent the side sheet 55 on the second side sheet 54 from interfering with the first adhesive sheet 531 when the second side sheet 54 is folded inward, which would cause wrinkles and damage to the carton. Therefore, when the cardboard 50 passes through the paper guide assembly 43, the first baffle 44211 must be in the second working state to make the packaging and forming action of the carton more reasonable. Regardless of the working state of the first baffle 44211, the second baffle 44212 is relatively fixedly set on the first conveying mechanism 41 to ensure proper limitation of the side sheet 55 and ensure accuracy.

[0049] The second folding and forming assembly 441 is positioned above the first conveying mechanism 41. The second folding and forming assembly 441 includes a rotary fourth conveying mechanism and several cushioning members 4412 and several pressure plate assemblies disposed on the fourth conveying mechanism. Each pressure plate assembly includes a first pressure plate 4411 and a second pressure plate 4413 spaced apart. Each cushioning member 4412 is disposed between the first pressure plate 4411 and the second pressure plate 4413 to allow the cushioning member 4412 to softly contact the top sheet 51. When each first pressure plate 4411 and the second pressure plate 4413 rotates from the upper side to the lower side of the fourth conveying mechanism, it folds inward to fold the second adhesive sheet 511. It can be understood that the interval between each pressure plate assembly is the interval between each cardboard 50 on the first conveying mechanism 41, and one pressure plate assembly corresponds to packaging one carton. Each buffer 4412 is disposed between the first pressure plate 4411 and the second pressure plate 4413 so that the buffer 4412 can softly contact the top page 51. The interval between the first pressure plate 4411 and the second pressure plate 4413 is the same as the interval between two adjacent second adhesive sheets 511 in a packaging box. The first pressure plate 4411 and the second pressure plate 4413 are rotatably disposed on the rotary fourth conveying mechanism. When the first pressure plate 4411 or the second pressure plate 4413 rotates from the upper side to the lower side of the fourth conveying mechanism, it will extend, which can just act on the second adhesive sheet 511 to fold it down. Then the first pressure plate 4411 and the second pressure plate 4413 continue to move on the lower side of the fourth conveying mechanism in the state of abutting the second adhesive sheet 511. When the first pressure plate 4411 and the second pressure plate 4413 rotate from the lower side to the upper side of the fourth conveying mechanism, they leave the carton, so that the carton can be smoothly discharged. It should be noted that the cushioning element 4412 includes an elastic, vertically floating contact surface for contacting the top page 51. When the contact surface makes soft contact with the top page 51, it can prevent damage to the carton and ensure packaging quality.

[0050] In some embodiments of the present invention, the paper guiding assembly 43 includes a first paper guiding roller 431, a second paper guiding roller 432, a third paper guiding roller 433, and a twisted guide plate 434. The first paper guiding roller 431 and the second paper guiding roller 432 are respectively disposed on both sides of the first conveying mechanism 41. The third paper guiding roller 433 is located downstream of the first paper guiding roller 431 and the second paper guiding roller 432. The guide plate 434 is located between the second paper guiding roller 432 and the third paper guiding roller 433. The first paper guiding roller 431 and the second paper guiding roller 432 extend from the outside to the inside to guide the first side page 52 and the second side page 54 to stand upright, respectively. The third paper guiding roller 433 extends gradually from the outside to the inside to guide the top page 51 to a horizontal position. The guide plate 434 has a paper guiding surface that gradually flattens from the outside to the inside to guide the third adhesive sheet 541 to a horizontal position. It is understood that the paperboard 50 has several creases, which allow it to be folded upright along the creases or unfolded along the creases. The first guide roller 431 and the second guide roller 432 are used to guide the flat first side page 52 and the second side page 54 to stand up, respectively. After the first side page 52 and the second side page 54 stand up, the top page 51 will also stand up and tilt within a certain range. A third guide roller 433 is set within this range to guide the top page 51 to a folded state, so that the top page 51 and the second side page 54 are attached together, completing the packaging. It should be noted that parts of the first guide roller 431 and the second guide roller 432 can be set to have a certain bending in space, extending from the outside to the inside and from low to high along the first direction. With the help of the conveying mechanism 41, the first side page 52 and the second side page 54 are gradually guided to stand up. Then, the first guide roller 431 and the second guide roller 432 continue to extend horizontally to maintain the standing state of the first side page 52 and the second side page 54. It is understandable that by twisting the guide paper 434, the third adhesive sheet 541, which is tilted within a certain range, can be received. The guide paper surface is set to a gradually flattened shape from the outside to the inside. With the help of the first conveying mechanism 41, the third adhesive sheet 541 is gradually guided from the upright state to the horizontal state and abuts against the top page 51. The whole process does not require the setting of a corresponding folding mechanism, and the packaging is completed during transportation, which improves packaging efficiency.

[0051] In some embodiments of the present invention, the paper feeding mechanism 30 includes a cardboard bin mechanism 31, a paper feeding mechanism 32, and a ramp mechanism 33. The cardboard bin mechanism 31 includes a fifth conveying mechanism for placing cardboard 50. The fifth conveying mechanism is used to convey the cardboard 50 to the paper feeding mechanism 32. After receiving the cardboard 50, the paper feeding mechanism 32 can sequentially distribute the cardboard 50. The ramp mechanism 33 is used to receive the distributed cardboard 50 and sequentially transport the cardboard 50 to the receiving station 451. It is understood that hundreds of cardboard 50 sheets can be stacked on the fifth conveying mechanism at one time, which greatly improves the utilization rate of the cardboard 50 bin, avoids frequent addition of cardboard 50, and reduces the workload of feeding operations. The paper feeding mechanism 32 automatically adjusts the cardboard 50 conveying and supply according to the speed of the fifth conveying mechanism and the ramp mechanism 33 to ensure smooth cardboard 50 supply. Furthermore, based on the arrangement of each mechanism, the ramp mechanism 33 is set to transport the cardboard 50 from bottom to top, ensuring that the way the cardboard 50 enters the production line is more reasonable and the station design when docking with the product is more scientific.

[0052] In some embodiments of the present invention, a buffer station for transition is provided between the climbing mechanism 33 and the paper feeding mechanism 32. The paperboard 50 distributed by the paper feeding mechanism 32 passes through the buffer station, and the climbing mechanism 33 receives and transports the paperboard 50 located at the buffer station. It is understood that the paperboard 50 distributed by the paper feeding mechanism 32 has a certain inertia. If it is directly fed into the climbing mechanism 33 for upward transport, the paperboard 50 may not be able to be positioned at the paper feeding station, resulting in errors in the coordination with other mechanisms. Therefore, without the need to reduce speed, a buffer station is set between the climbing mechanism 33 and the paper feeding mechanism 32 so that the paperboard 50 can be transported more stably by the climbing mechanism 33.

[0053] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
