Description

Technical Field

[0001] This utility model relates to the technical field of lid box production equipment, and more particularly to a fully automatic lid box forming machine. Background Technology

[0002] A top-and-bottom box is a type of box where the lid is the "sky" and the bottom is the "earth," hence the name. It is widely used in various types of packaging boxes, such as high-end gift boxes, shoe boxes, underwear boxes, shirt boxes, and mobile phone boxes.

[0003] The bottom of a hinged box is mainly made of face paper and cardboard. The traditional manufacturing method involves cutting right angles off all four sides of a rectangular cardboard piece, then creating V-grooves along these angles. During manufacturing, the cardboard is glued to the face paper, the four sides of the cardboard are then folded up, and the edges of the face paper are folded inwards to the inner wall of the cardboard, thus forming the bottom. Because this process requires cutting off the four right angles of the cardboard, it results in significant waste of cardboard material, increases production costs, and is also environmentally unfriendly.

[0004] To address the aforementioned material waste issue, the bottom box can be manufactured using the following process, as shown in the attached diagram. Figure 12 As shown, the following components are required: face paper 100, cardboard 101, and two second side panels 102. Face paper 100 includes a bottom surface 100a, two first side panels 100b, two second side panels 100c, and four flaps 100d. Cardboard 101 includes a bottom panel 101a that matches the bottom surface 100a, two first side panels 101b that mate with the first side panels 100b, and two second side panels 102 that mate with the second side panels 100c. During production, glue is first applied to the top surface of the face paper 100. Then, cardboard 101 is placed on the top surface of the face paper 100. The bottom panel 101a and the two first side panels 101b are aligned with the bottom surface 100a and the two first side panels 100b, respectively. Glue is then applied to both sides of the bottom panel 101a. The two second side panels 102 are then erected and their bottom ends are glued to both sides of the bottom panel 101a. The two first side panels 101b are then erected, and the four flaps 100d are folded inward and glued to the outer side surface of the second side panels 102. The excess portion of the first side panels 100b is then folded inward and glued to the inner wall of the first side panels 101b. The two second side panels 100c are then erected and glued to the outer wall of the second side panels 102. The excess portion of the second side panels 100c is then folded inward and glued to the inner wall of the second side panels 102, thus forming the bottom box 10. Existing production equipment for top and bottom boxes is only suitable for traditional bottom box production processes and is not suitable for new production processes. It cannot solve the problem of cardboard material waste, resulting in high bottom box production costs and environmental problems. These issues urgently need to be addressed. Utility Model Content

The first side plate loading station 7 and the second side plate loading station 8 both supply side paperboards to the forming station 9. The forming station 9 is used to drive the composite paperboard to the first side lifting station 11 and the ear folding station.

[0030] Its working principle is as follows: two second side panels 102 are respectively placed on the first side panel loading station 7 and the second side panel loading station 8. The composite paperboard is picked up and placed on the forming station 9 by the composite paperboard loading and unloading station 6. Then, the first side panel loading station 7 and the second side panel loading station 8 respectively convey the two second side panels 102 to the forming station 9. The forming station 9 glues the two second side panels 102 to the two side edges of the paperboard 101. The forming station 9 then carries the... The composite paperboard is transferred between the first side lifting station 11, the ear folding station 12, the first side inward folding station 13, the first side bubble pressing station 14, the second side lifting station 15, the second side inward folding station 16, and the second side bubble pressing station 17. The first side lifting station 11 erects the two first side panels 101b and the first side surface 100b. The ear folding station 12 folds the four ears 100d inward and glues them to the outer wall of the second side panel 102. When the side folding station 13 folds the excess parts of the two first side panels 100b inward toward the center, the forming station 9 folds the excess parts of the first side panels 100b inward and glues them to the inner wall of the first side panel 101b. The first side bubble pressing station 14 performs bubble pressing operation between the first side panel 101b and the first side panel 100b. When the second side lifting station 15 folds the excess parts of the two second side panels 100c inward toward the center, the forming station 9 folds the excess parts of the second side panels 100c inward and glues them to the inner wall of the second side panel 102. The second side bubble pressing station 17 performs bubble pressing operation between the second side panel 102 and the second side panel 100c. Then, the composite paperboard unloading station 6 takes the bottom box 10 from the forming station 9 and outputs the unloading material. This realizes the automated forming of the bottom box, which is suitable for new bottom box production processes, solves the problems of paperboard material waste and high production costs, conforms to the concept of environmental protection, and is worth promoting and using.

[0031] Based on the above embodiments, the system also includes a frame 19. The composite paperboard loading and unloading station 6 includes two symmetrically arranged loading and unloading mechanisms 60. Each loading and unloading mechanism 60 includes a first frame 61 slidably connected to the frame 19 along the X-axis direction, an X-axis adjusting screw 62 rotatably connected to the first frame 61, a first Y-axis slide block 63 slidably connected to the bottom of the first frame 61 along the X-axis direction, a loading drive cylinder 64 disposed on the first frame 61 and drivenly connected to the first Y-axis slide block 63, and a first Y-axis linear drive mechanism disposed on the first Y-axis slide block 63. 65.

The clamping assembly includes a clamping cylinder 68 fixedly connected to one end of the Y-axis arm plate 66 and a clamping plate 69 driven by the clamping cylinder 68. A first internal threaded sleeve matching the X-axis adjusting screw 62 is disposed on one side of the first frame 61, and the X-axis adjusting screw 62 is connected to the first internal threaded sleeve. Specifically, by rotating the X-axis adjusting screw 62, the first frame 61 can be moved left and right. By adjusting the X-axis orientation of the two first frames 61, the distance between the two Y-axis arm plates 66 can be adjusted to accommodate the loading and unloading operations of composite paperboards of different widths. When the clamping cylinder 68 is working, it can drive the first Y-axis slide 63 to move left and right. When the first Y-axis linear drive mechanism 65 is working, it can drive the Y-axis arm plate 66 to move back and forth. The clamping plate 69 can move left and right under the drive of the clamping cylinder 68. When the composite paperboard is conveyed to one side of the composite paperboard loading and unloading station 6, the first suction cups 67 on the Y-axis arm plates 66 on both sides can be allowed to pick up the composite paperboard and convey it to the forming station 9. After the bottom box 10 is formed, the clamping plates 69 on both sides can be brought close together to clamp the bottom box 10 and output the unloading material.

[0032] Based on the above embodiments, both the first side plate loading station 7 and the second side plate loading station 8 include a side plate hopper mechanism 70, a side plate pushing mechanism 71, and a flipping feeding mechanism 72. The side plate hopper mechanism 70 includes an X-axis limiting plate 700 slidably connected to the first frame 61 along the Y-axis direction and a Y-axis adjusting screw 701 rotatably connected to the first frame 61. A second internal threaded sleeve matching the Y-axis adjusting screw 701 is provided through the X-axis limiting plate 700. The Y-axis adjusting screw 701 is connected to the second internal threaded sleeve. A first right-angle limiting groove 700a is provided on the inner side of the top of the X-axis limiting plate 700. The side plate pushing mechanism 71 includes a first X-axis slide block 710 fixedly connected to the first frame 61, a side plate pushing plate 711 slidably connected to the top of the first X-axis slide block 710 along the X-axis direction, and a first X-axis linear drive that is disposed on the first X-axis slide block 710 and drivenly connected to the side plate pushing plate 711. The moving mechanism 712 has a first right-angle push groove 711a on the top of the side plate push plate 711, and a first guide arc surface 711b and a second guide arc surface 711c on both sides of the first right-angle push groove 711a. The flipping feeding mechanism 72 includes a flipping mechanism and a feeding mechanism. The flipping mechanism includes a rotating support 720 that is slidably connected to both sides of the first frame 61 along the X-axis, a rotating shaft 721 that is rotatably connected between the two rotating supports 720, and a flipping drive motor 722 that is set on one of the rotating supports 720 and drivenly connected to one end of the rotating shaft 721. The feeding mechanism includes a feeding drive cylinder 723 set on the rotating shaft 721 and a suction cup assembly. The suction cup assembly includes two first guide rods 724, a connecting beam 725 that is fixedly connected between the top ends of the two first guide rods 724, and a second suction cup 726 installed at the bottom end of the first guide rods 724. The first guide rods 724 and the rotating shaft 721 are connected by bushings. Specifically, by rotating the Y-axis adjusting screw 701, the two X-axis limiting plates 700 can be moved closer or further away, thereby adjusting the width between the two first right-angle limiting grooves 700a to accommodate the limiting of the second side plate 102 of different lengths. The second side plate 102 is stacked between the two first right-angle limiting grooves 700a. The height of the first right-angle pushing groove 711a should be less than or equal to the thickness of the second side plate 102. Initially, the side plate pushing plate 711 is located behind the material stack of the second side plate 102. During feeding, the side plate pushing plate 711 is driven to move forward along the first X-axis slide block 710 by the first X-axis linear drive mechanism 712. The second guide arc surface 711c will pass through the bottom of the material stack of the second side plate 102 and lift the material stack of the second side plate 102. The bottommost second side plate 102 will be stuck on the first right-angle pushing groove 711a and pushed to the flipping feeding mechanism 72. Then, the first X-axis linear drive mechanism 712 drives the side plate pushing plate 711 to retract and reset. The first guide arc surface 711b will pass through the bottom of the material stack of the second side plate 102 and lift the material stack of the second side plate 102.
