[0027] The present utility model will be specifically described below through embodiments, which are only used for further illustration of the present utility model and should not be construed as limiting the protection scope of the present utility model.

[0028] As Figure 3 — Figure 6 shown, this embodiment discloses a fruit box assembly device, including a frame 1. There is an assembly position 2 arranged inside the frame 1. A cardboard positioning groove 3, a shaping die 4 and a backing plate 5 are arranged in the vertical direction of the assembly position 2. The shaping die 4 and the backing plate 5 are driven by their respective driving members to move up and down. Retractable shaping plates 6 are respectively arranged on the left and right sides of the assembly position 2, and side plate positioning dies 7 that can move forward and backward are respectively arranged on the front and back sides of the assembly position 2. The shaping die 4 includes a pneumatic claw 41 connected to an air pump through a solenoid valve. Four telescopic plates that are symmetrically arranged in pairs are arranged on the pneumatic claw 41. A shaping pressing plate 42 is connected to the telescopic plates. In this way, the four shaping pressing plates 42 arranged in the front, back, left and right directions are telescopically arranged. The bottom of the outer end of the shaping pressing plate 42 extends to be provided with an outward extending pressing block. An inclined surface 43 extending to the bottom surface of the shaping pressing plate is arranged on the outside of the outward extending pressing block. A pointed part 433 is formed between the inclined surface 43 and the bottom surface of the shaping pressing plate.

[0029] The side plate positioning die 7 is driven by a first cylinder 10, and the expansion and contraction of the shaping plate 6 is driven by a second cylinder 20. The first cylinder 10 and the second cylinder 20 are respectively fixed on the frame 1. The side plate positioning die 7 includes a seat body 71, a lower positioning die 72 and an upper positioning die 73. A first guide rail 730 is arranged on the cylinder body of the first cylinder 10. The seat body 71 is installed on the first guide rail 730 to slide. The upper and lower positioning dies 72 of the seat body 71 are arranged on the front end surface of the seat body 71. A lifting cylinder 74 is arranged on the seat body 71. The piston rod of the lifting cylinder 74 is connected to the upper positioning die 73 through a connecting plate, so that the upper positioning die 73 is arranged above the lower positioning die 72 to move up and down telescopically. After the upper positioning die 73 moves down, a side plate positioning groove is formed with the lower positioning die 72. Therefore, the side plate positioning groove can be opened or closed at any time through the lifting cylinder 74. When in the open state, the side plate can be placed or released, and the side plate is positioned after closing. In this way, the side plate is extended through the first cylinder 10 and assembled with the cardboard folded and formed at the installation position. After the cardboard and the side plate are assembled in cooperation, the upper positioning die 73 is lifted to release the side plate, and then the seat body 71 returns to its original position.

[0030] The cardboard positioning groove 3 includes a first support plate 31, a second support plate 32, two positioning baffles 33 and a limit block 34. The space between the first support plate 31 and the second support plate 32 forms a folding feeding port 35, which is adapted to the bottom paper surface of the cardboard. The folding feeding port is aligned above the assembly position 2. Brush rollers 36 are respectively arranged on both sides of the folding feeding port 35. Positioning cylinders 36 corresponding one by one to the positioning baffles 33 are arranged on the first support plate. The positioning baffles 33 are connected to the positioning cylinders 36, and the limit block 34 is connected to the first support plate 31. The positioning baffles 33 extend to the second support plate 32, and the cross section of the positioning baffle is "L" shaped. After the unfolded cardboard is placed in the cardboard positioning groove 3, the positioning baffles 33 on both sides simultaneously pat and position the side edges of the cardboard through the positioning cylinders 36, and the front end of the cardboard contacts the limit block 34 for positioning, realizing the horizontal and vertical positioning of the cardboard. At the same time, the bottom paper surface of the cardboard (the bottom surface when folded into a box body) is located at the folding inlet, and the forming die 4 transfers it to the assembly position 2. When the cardboard passes through the folding feeding port and moves down, it folds along the crease. If there are tongue tabs on both sides of the bottom paper surface of the cardboard, when the positioning baffles 33 are in the retracted state, the tongue tabs will also be pre-folded, and the brush rollers can reduce the surface wear of the cardboard during bending.

[0031] Above the second support plate 32, a cardboard storage bin 37 is erected. The cardboard storage bin 37 is surrounded by four angle steels. At the lower discharge port of the cardboard storage bin 37, two material blocking straight rods are provided to support the bottom surface of the cardboard. An active suction cup 38 is arranged below the cardboard storage bin 37. During operation, the suction cup 38 adsorbs the cardboard at the bottom of the cardboard storage bin 37 and places it on the second support plate 32. A push plate 39 is arranged on the second support plate 32, and the push plate 39 is arranged to move back and forth. An opening groove through which the push plate 39 passes and moves along is provided on the second support plate 32. A push cylinder 401 is connected to the movable seat of a linear motion module 40, and the push plate 39 is installed on the piston rod of the push cylinder 401. In this way, the suction cup 38 drags the cardboard at the bottom of the cardboard storage bin 37 through the material blocking straight rods to the second support plate 32, and then the push plate 39 pushes it to the cardboard positioning groove 3 for positioning. The suction cups 38 are arranged in sequence on a lifting plate 51, and the lifting plate 51 is driven by a lifting cylinder 74. The suction cups 38 are also connected to an air pump through another solenoid valve.

[0032] Specifically, as Figure 7 、 Figure 8As shown in the figure, it also includes a side plate conveying mechanism 8. The side plate conveying mechanism 8 includes a side plate conveyor belt 81. Above the side plate conveyor belt 81, two limit baffle plates 82 are erected. Between the output port position of the side plate conveyor belt 81 and the lower positioning die 72, a side output support plate 83 is connected. In front of the output port of the side plate conveyor belt 81, a push baffle 84 is provided. A push block 841 is installed at the side end of the push baffle 84. The push baffle 84 is driven by a driving mechanism 9 to move along the length direction of the side output support plate 83. The side plates can be stacked upright on the side plate conveyor belt 81 and are limited and conveyed by the two limit baffle plates 82. At the same time, a heavy block 810 is placed on the side plate conveyor belt 81 to prevent the stacked side plates from tipping over. When the side plates are conveyed to the output port position, the pressing plate 85 arranged above is driven by a common air cylinder to move down and hit the side plates at this position, so that the bottom of the side plates is attached to the output support plate 83 and the front abuts against the push baffle 84. The side push block 841 on the push baffle 84 pushes it into the lower positioning die 72. Subsequently, the upper positioning die 73 moves down, so that it is conveyed into the side plate positioning die 7 for positioning.

[0033] The driving mechanism 9 includes a second guide rail 91, a first sliding seat 92, a first lead screw 93 and a first motor 94. The first sliding seat 92 is installed on the second guide rail 91 to slide. The side end of the second guide rail 91 is connected with the first motor 94 through a connecting plate. The first lead screw 93 is connected to the output shaft of the first motor 94. The push baffle 84 is connected with the first sliding seat 92. In this way, the side shift of the push baffle 84 can be made more reliable and stable.

[0034] A vertical third guide rail 44 is provided corresponding to the forming die 4. On the third guide rail 44, a second sliding seat 45 is configured to slide along it. The forming die 4 is installed on the second sliding seat 45. On the third guide rail 44, a rack is arranged along its length. On the second sliding seat 45, a second motor is configured. A gear is installed on the output shaft of the second motor, and this gear is in meshing transmission cooperation with the rack. In this way, the forming die 4 has a longer movement stroke to ensure the transfer of the cardboard. A lifting plate 51 is provided corresponding to the backing plate 5. The lifting plate 51 is installed on a vertical guide rod to move vertically and guide. A top material air cylinder 52 is arranged on the lifting plate 51. It also includes a second lead screw 53 and a third motor 54. The second lead screw 53 is in threaded transmission connection with the lifting plate 51. The output shaft of the third motor 54 is connected with the second lead screw 53. Through the second lead screw 53, the lifting stroke of the backing plate 5 can be further increased, so that it has enough stroke to cope with the up and down movement of the cardboard, and the occupied space is small. The third guide rail 44 can also be adjusted in the left and right positions through conventional structures such as guide rails and lead screws, and then the position of the forming die is adjusted.

[0035] As Figure 9As shown in the figure, blocking blocks 61 are respectively arranged on both sides of the shaping plate 6. Two guiding straight rods 62 and spring sleeve rods 62 are connected to the blocking block 61. A guiding hole groove 63 is provided at the side end of the shaping plate 6. An active block 64 is arranged in the guiding hole groove 63. A sealing plate 65 is configured at the opening end of the guiding hole groove 63, so that the active block 64 is restricted to move within the guiding hole groove 63. The guiding straight rod 62 penetrates into the guiding hole groove 65 and is connected to the active block 64. A spring hole groove 66 is also provided at the side end of the shaping plate 6. A spring 67 is arranged between the spring hole groove 66 and the spring sleeve rod 62. When the side plate is pushed towards the installation position to cooperate with the folded cardboard, the side plate contacts and compresses the blocking block. After the blocking blocks on both sides of the shaping plate are compressed to the bottom, they can block the further advancement of the side plate, thereby avoiding the compression deformation of the cardboard.

[0036] Working principle: After the cardboard 100 is horizontally stacked in the cardboard storage bin 37, it is dragged to the second support plate 32 by the suction cup 38. Subsequently, the cardboard is pushed to the cardboard positioning groove 3 by the push plate 39 for positioning. At this time, the four forming pressing plates 42 on the forming die 4 extend out, and the bottom corners of the forming pressing plates 42 press against the folding crease of the cardboard. After the forming die moves down through the folding feeding port 35, the two side edges of the cardboard are folded upward along the folding line. Subsequently, the forming die continues to push the cardboard towards the cushion plate 5 waiting at the assembly position 2. After the cushion plate 5 holds the transferred cardboard, the shaping plates 6 on both sides extend out and press against the outer pointed parts 433 of the forming pressing plates 42, prompting the angle between the side and the bottom surface of the cardboard to form a right angle, so that the cardboard forms a shape as Figure 2 shown in the figure, enabling the cardboard to be folded into a ready state for cooperation with the side plate. Subsequently, the four forming pressing plates 42 on the forming die 4 retract, and the forming die rises and returns to its original position. When the forming pressing plates 42 retract, they can avoid contacting the protruding parts on the side plate during the return process, preventing the situation of hitting the side plate. The two side plates 200 are respectively transported to the side plate positioning die 7 through the side plate conveying mechanism 8, and the side plate positioning die 7 is driven by the first cylinder 10 to push over and perform concave-convex insertion with the formed cardboard, so that the side plates are installed on the folded cardboard to form a fruit box. The assembled fruit box moves down with the cushion plate 5 to the output belt 30 and is pushed into the output belt 30 by the poking cylinder for output.

[0037] To achieve automation, a control processor, sensors, and an industrial automation system (industrial PLM automation system) can also be configured on this device, mainly controlling various controlled components such as solenoid valves, cylinders, and motors, and coordinating the accurate completion of the actions of each component.

[0038] With the above technical solution, the cardboard to be folded can be directly placed at the cardboard feeding slot, and the forming die 4 brings the cardboard at the cardboard positioning slot 3 into the assembly position 2. The side plates are placed on the side plate positioning die 7 and pushed into the assembly position 2 to be inserted and matched with the side edges and bottom edges on both sides after the cardboard is folded, completing the assembly of the fruit box. In this way, the technical effect of quickly assembling the side plates and the outer box is achieved, thus greatly reducing the labor cost, improving the assembly efficiency, having good assembly quality, and reliable and stable structure.

[0039] This equipment can also, according to the folding requirements of the cardboard, install the forming die 4 on the backing plate 5 and replace the position of the forming die 4 with a pressing plate, so that the cardboard is pressed into the forming die 4 by the pressing plate and folded into a box shape, achieving the function of multi-purpose use of one machine.
