[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, a cardboard automatic stacking and packaging device includes a device shell 3, a stacking structure 5 is arranged at the front of the inner cavity of the device shell 3, a whole material structure 7 is arranged at the rear of the inner surface of the stacking structure 5, a packaging structure 6 is arranged on the inner surface of the stacking structure 5, a stacking structure 4 is arranged on the upper part of the inner surface of the stacking structure 5, and a feeding conveyor belt 1 and a discharging conveyor belt 2 are respectively arranged on the upper and lower parts of the inner surface of the stacking structure 5.

[0036] During the operation of this embodiment, the cardboard is intermittently fed into the stacking structure 5 through the cooperation of the feeding conveyor belt 1 and the coding structure 4, and the cardboard is sorted through the cooperation of the stacking structure 5 and the sorting structure 7 to avoid the cardboard dislocation affecting the subsequent packaging effect; after stacking to a certain number, the cardboard is packaged through the cooperation of the stacking structure 5 and the packaging structure 6, and at the same time, the new cardboard is blocked from falling through the action of the packaging structure 6 on the coding structure 4 to avoid the subsequent cardboard from affecting the packaging. After the packaging is completed, the packaged cardboard is sent out through the discharging conveyor belt 2 by the cooperation of the packaging structure 6 and the sorting structure 7, so as to realize continuous stacking and packaging.

[0037] It should be specially noted that the above-mentioned feed conveyor belt 1 and discharge conveyor belt 2 are both connected to external feeding and receiving devices, and are only used to transport cardboard and packaged cardboard material packages. Their driving mode is also the driving mode of conventional material conveying devices, which has been widely used in the prior art. In the present invention, their specific structure and operating principle will no longer be displayed and explained.

[0038] Embodiment 2

[0039] On the basis of the first embodiment, the present embodiment cooperates with the stacking fan blades 42, the central axis 41 and the intermittent structure 43 to enable the cardboard to fall on the upper part of the L-shaped supporting plate 52 through the limiting pillars 2 53 arranged on both sides of the inner cavity of the stacking chamber 51, and gradually accumulate. The weight presses the L-shaped supporting plate 52 to descend along the cross slide 2 55, so that the cardboard is gradually stacked, avoiding the cardboard from being messy and distorted during the stacking process, reducing the impact on the subsequent packaging process and warehousing process, and also avoiding the damage of the uneven cardboard during transportation, thereby ensuring the product quality.

[0040] Specifically, to achieve the stacking of cardboard, refer to Figure 4 and Figure 5 The stacking structure 5 includes a stacking chamber 51 fixedly connected to the middle part of the inner cavity of the device shell 3, and two cross slide grooves 55 are symmetrically provided on the inner surface of the stacking chamber 51. The inner surfaces of the two cross slide grooves 55 are slidably connected with L-shaped bearing plates 52, and the lower ends of the two L-shaped bearing plates 52 close to each other are fixedly connected together. The upper ends of the two L-shaped bearing plates 52 are fixedly connected with compression springs 54 fixedly connected to the lower end of the stacking chamber 51, and four limit columns 53 are fixedly connected to the bottom wall of the inner surface of the stacking chamber 51 in a rectangular distribution.

[0041] When the cardboard falls into the stacking chamber 51, it will be guided by the limiting columns 53 on both sides and fall on the upper part of the L-shaped supporting plate 52. The gradual accumulation of cardboard will force the L-shaped supporting plate 52 to slide downward in the cross slide groove 55. At this time, the compression spring 54 is stretched and gradually accumulated until the cardboard contacts the packaging structure 6.

[0042] Further, in order to guide the paperboard to fall onto the L-shaped bearing plate 52 in the inner cavity of the stacking chamber 51 along the limiting column 53, refer to Figure 4 The material coding structure 4 includes installation grooves 44 which are symmetrically opened at the upper end of the stacking chamber 51. The inner surfaces of the two installation grooves 44 are rotatably connected with the central shaft 41. The outer surfaces of the two central shafts 41 are linearly distributed and fixedly connected with a plurality of material coding blades 42. The rear ends of the central shafts 41 are provided with intermittent structures 43.

[0043] A blocking plate is provided at the junction of the feeding conveyor belt 1 and the upper part of the stacking chamber 51 so that only paperboard can enter through this plate. This blocking plate will block materials exceeding a predetermined thickness and force them to queue up and enter the action range of the stacking structure 4.

[0044] When the cardboard enters the stacking fan blades 42, the stacking fan blades 42 cannot rotate due to the action of the intermittent structure 43, and the cardboard will overlap the blades of the stacking fan blades 42 on both sides until the cardboard completely enters the predetermined position at the top of the stacking chamber 51 and presses the intermittent structure 43 to move backward. At this time, the stacking fan blades 42 will rotate and drive the cardboard to fall into the stacking chamber 51.

[0045] Further, in order to make the cardboard completely reach the upper side of the L-shaped carrying plate 52 before falling into the stacking chamber 51, refer to Figure 6 and Figure 7 The intermittent structure 43 includes a cross slide 437 opened at the rear end of the mounting groove 44, the front part of the inner surface of the cross slide 437 is rotatably connected with a connecting shaft 431 fixedly connected to the rear end of the central shaft 41, the inner surface of the connecting shaft 431 is rotatably connected with a limiting column 432, the rear end of the central shaft 41 located in the inner cavity of the connecting shaft 431 is rotatably connected with a compression spring 434 rotatably connected to the front end of a spring ejector pin 435, a plurality of spring ejector pins 435 slidably connected to the inner surface of the N-shaped slide 433 are slidably connected in an annular distribution on the outer surface of the limiting column 432, the ends of the limiting columns 432 on both sides close to each other are fixedly connected with a baffle 436, and the inner surface of the cross slide 437 is slidably connected to the packaging structure 6.

[0046] When the cardboard pushes the baffle 436 backward, it will simultaneously push the limiting column 432 to move backward. At this time, the spring ejector 435 will move along the N-shaped slide groove 433. Since the limiting column 432 is in the cross slide groove 437, it can only slide but not rotate due to the restriction of the cross slide groove 437. Therefore, under the guidance of the N-shaped slide groove 433, the connecting shaft 431 will rotate, thereby prompting the coding fan blade 42 to rotate, thereby causing the cardboard to fall into the stacking chamber 51.

[0047] Further, to achieve intermittent guidance of the cardboard falling, refer to Figure 7 The N-shaped slide 433 is an N-shaped track distributed in a ring shape, wherein two adjacent N-shaped vertical parts overlap, and its running track is a one-way cycle of the rear part of the vertical part - the inclined part - the front part of the adjacent vertical part - the rear part of the adjacent vertical part.

[0048] The N-shaped slide groove 433 can rotate the connecting shaft 431 through the guidance of the spring ejector pin 435. Each operation can prompt the next fan plate of the coding fan blade 42 to rotate to a horizontal position to receive the next cardboard. There are slopes and drops inside it to limit the running path to remain unidirectional.

[0049] Embodiment 3

[0050] On the basis of the second embodiment, this embodiment arranges the front and rear directions of the cardboard through the cooperation of the electric telescopic rod 73, the push plate 71 and the front limit structure 74, thereby reducing the influence of the slight deviation of the cardboard during the falling process on the packaging quality. At the same time, the cooperation of the linkage rod 745 and the packaging structure 6 is utilized to push the packaged cardboard material package to the upper part of the discharge conveyor belt 2 through the push plate 71 and the electric telescopic rod 73 after the packaging is completed, thereby realizing continuous operation.

[0051] Specifically, to align the front and back positions of the cardboard, refer to Figure 5 The material-forming structure 7 includes an electric telescopic rod 73 fixedly connected to the rear end of the stacking chamber 51, the output end of the electric telescopic rod 73 passes through the rear end of the stacking chamber 51, extends to the inner cavity of the stacking chamber 51 and is fixedly connected to a pushing plate 71, and four limit rods 72 are fixedly connected to the rear end of the electric telescopic rod 73 in a rectangular distribution and slidingly connected to the stacking chamber 51 through through holes, and a front limit structure 74 is symmetrically arranged on the left and right sides of the front inner cavity of the stacking chamber 51.

[0052] After the cardboard falls, the push plate 71 is pushed by the electric telescopic rod 73 and the two front limiting structures 74 at the front can make the cardboard in a neat state to avoid front and rear misalignment.

[0053] Furthermore, in order to push out the packed cardboard pile without affecting the discharge of the cardboard bales, refer to Figure 8 The front limiting structure 74 includes sliding rods 741 which are symmetrically distributed in the upper and lower parts and are slidably connected to the stacking chamber 51 through the grooves. The ends of the two sliding rods 741 which are close to each other and are located in the inner cavity of the stacking chamber 51 are fixedly connected with a roller 744. The ends of the two sliding rods 741 which are away from the roller 744 are fixedly connected with a limiting rod 2 743. The side of the limiting rod 2 743 which is close to the outer end surface of the compression spring 2 54 is fixedly connected with a tension spring 742 which is fixedly connected to the end surface of the adjacent stacking chamber 51. The ends of the two sliding rods 741 which are close to each other and are located between the inner wall of the stacking chamber 51 and the roller 744 are fixedly connected with a linkage rod 745.

[0054] In order to avoid affecting the discharging of materials, a linkage rod 745 that can follow the response of the packaging structure 6 is set between the two sliding rods 741 on the same side, so that during the packaging process, the rollers 744 on both sides are moved away from each other through the action of the packaging structure 6, thereby canceling the limitation of the cardboard material package at the front.

[0055] Embodiment 4

[0056] In this embodiment, on the basis of the third embodiment, when the cardboards piled on the L-shaped bearing plate 52 fall to the position of the T-shaped column 631, the gravity is used to drive the balers 61 on both sides to move inward. When the balers 61 are close to a certain distance, the cardboards are packaged by the balers 61, and the front limiting structure 74 is driven to expand outward to cancel the limitation of the cardboard pile by the action of the wedge block 66. The cardboard pile is pushed to the discharge conveyor belt 2 through the bearing slide rail 64 and sent out by the electric telescopic rod 73. At the same time, the blocking rod 62 and the intermittent structure 43 are used to prevent the subsequent cardboards from falling, so as to avoid affecting the packaging process, thereby simplifying the packaging process and improving the automatic efficiency.

[0057] Specifically, in order to realize the packaging of cardboard after a certain amount of cardboard is piled up, refer to Figure 8 , Fig. 9 , Fig.10 and Fig.11 The packaging structure 6 includes a packaging machine 61 symmetrically distributed front and back and slidably connected to the inner surface of the stacking chamber 51 through a limit rod. A packaging response component 63 is provided on the bottom wall of the inner cavity of the stacking chamber 51. The upper end of the packaging machine 61 at the rear is symmetrically fixedly connected to a blocking rod 62 slidably connected to the inner surface of an adjacent cross slide 437. The rear end of the packaging machine 61 at the front is symmetrically fixedly connected to a wedge block 66 tightly attached to the adjacent linkage rod 745. The lower end of the stacking chamber 51 is symmetrically fixedly connected to a tie disk 65 front and back. The lower end of the stacking chamber 51 is symmetrically fixedly connected to a load-bearing slide rail 64, and the load-bearing slide rail 64 is consistent in height with the discharge conveyor belt 2.

[0058] It should be particularly noted that the baler 61 is a conventional cable tie baling device, which is internally provided with a plurality of symmetrically distributed rollers for driving the cable tie to move around its internal path, and the loose cable tie is tightened by the tightening component at the bottom to make it close to the surface of the cardboard and then hot-melted together and cut off, thereby achieving the baling effect. The baling device is a mature technical means in the prior art, and is only used in the present invention to achieve the baling function, and its internal specific structure and operating principle will not be displayed and explained in detail.

[0059] A plurality of ball bearings for reducing friction are arranged on the upper part of the packaging response component 63. When the electric telescopic rod 73 pushes the cardboard material package through the pushing plate 71, the load-bearing slide rail 64 can be used to cause the material package to move outward and enter the discharge conveyor belt 2 and be taken out by the action of the discharge conveyor belt 2.

[0060] Further, to pack the cardboard after stacking, see Figure 8 , Fig. 9 , Fig.10 and Fig.11The packaging response component 63 includes a T-shaped column 631, and a cross slide groove three 635 is symmetrically opened in the front and back of the lower part of the inner cavity of the stacking chamber 51. The lower end of the horizontal part of the T-shaped column 631 is fixedly connected to a compression spring three 632 fixedly connected to the bottom wall of the inner cavity of the stacking chamber 51. The vertical part of the T-shaped column 631 penetrates the inner cavity of the stacking chamber 51 and extends to the lower end of the stacking chamber 51. The outer surface of the T-shaped column 631 is symmetrically rotatably connected to a connecting rod 633 that is slidably connected to the inner surface of the adjacent cross slide groove three 635. The ends of the two cross slide grooves three 635 away from the T-shaped column 631 are rotatably connected to an articulated seat 634, and the upper ends of the two articulated seats 634 are respectively fixedly connected to the lower ends of the adjacent balers 61.

[0061] When the cardboard on the T-shaped column 631 is piled up to a certain weight, the connecting rod 633 drives the hinge seat 634 to slide, thereby driving the balers 61 on both sides to move inward in the stacking chamber 51 until the cardboard enters the action range of the baler 61, and then the cardboard is baled by the baler 61;

[0062] At the same time, under the action of the wedge block 66, the sliding rod 741 drives the rollers 744 on both sides to move away from each other due to the action of the linkage rod 745, and separates from the front edge of the paperboard, thereby releasing the limit on the paperboard.

[0063] Further, to prevent new cardboard from falling during the packaging process, refer to Figure 6 The blocking rod 62 is L-shaped, and its horizontal part is located on the inner surface of the cross slide groove 437 and is in close contact with the rear end of the limiting column 432 when it is at the frontmost part.

[0064] In order to prevent subsequent cardboard from falling and affecting the packaging effect, the blocking rod 62 will be driven to slide in the cross slide 437 during the movement of the baler 61 until the blocking rod 62 contacts the limiting column 432 to block the movement of the limiting column 432.

[0065] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
