Description

Technical Field

[0001] The present invention relates to the technical field of plastic hollow plate processing equipment, and in particular to a stacking system for processed plastic hollow plates. Background Art

[0002] Plastic hollow board is a hollow structural board made of plastic materials such as polypropylene (PP) and polyethylene (PE) through a hot pressing process. It has a corrugated surface morphology and is usually composed of two layers of flat boards and a corrugated layer in the middle, forming a honeycomb-like structure. This structure gives it good strength, rigidity and lightness. In the processing and production of plastic hollow boards, in order to facilitate subsequent storage, transportation and management operations, the processed plastic hollow boards usually need to be stacked.

[0003] However, the existing stacking method has obvious defects. In the traditional stacking mode, a large number of plastic hollow boards are stacked layer by layer, and the plastic hollow board at the bottom bears the weight of all the plastic hollow boards above it. As the stacking height increases, the pressure on the bottom plastic hollow board increases sharply, which can easily cause deformation, cracking and other damage to the bottom plastic hollow board. Once the bottom plastic hollow board is damaged, it will not only affect the stability of the entire pile of plastic hollow boards, but may also cause safety accidents such as collapse during handling or transportation. Moreover, the damaged plastic hollow board cannot be used normally, resulting in material waste and economic losses. Therefore, there is an urgent need for a new stacking system that can effectively relieve the pressure of the bottom plastic hollow board and prevent it from being damaged during the stacking process.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, refer to Figure 1-Figure 8 A stacking system for processed plastic hollow plates, comprising a belt conveyor 1, a manipulator 2 is arranged on the side of the belt conveyor 1, a vacuum suction head 3 is installed on the manipulator 2, a stacking box 4 is also arranged on the side of the belt conveyor 1, and an inner cavity 5 is opened in the stacking box 4, and further comprising: The load-bearing mechanism is arranged in the belt conveyor 1. When the plastic hollow plates dropped into the belt conveyor 1 reach a predetermined weight, the load-bearing mechanism is used to apply pressure to the bottom plastic hollow plates. An adjusting mechanism 1 is installed on the load-bearing mechanism, and the adjusting mechanism 1 is used to apply pressure to the upper plastic hollow plate from both sides.

[0022] Furthermore, the load-bearing mechanism includes an elastic plate 61 sliding in the stacking box 4, a liquid storage cylinder 62 is fixed in the inner cavity 5, a lifting rod 63 is fixed to the bottom of the elastic plate 61, the lifting rod 63 slides in the liquid storage cylinder 62, a piston disk 64 is fixed to the bottom end of the lifting rod 63, the piston disk 64 slides in the liquid storage cylinder 62, and a spring 65 is sleeved on the outer surface of the lifting rod 63, and the two ends of the spring 65 are respectively fixedly connected to the elastic plate 61 and the liquid storage cylinder 62.

[0023] Furthermore, the load-bearing mechanism also includes a hose 66 connected to the liquid storage cylinder 62, and a fixed cylinder 67 is fixed on the belt conveyor 1. The end of the hose 66 away from the liquid storage cylinder 62 is connected to the fixed cylinder 67. A piston disk 68 slides in the fixed cylinder 67, and a moving rod 60 is fixed on the piston disk 68. A moving shell 69 is fixed to the end of the moving rod 60 away from the piston disk 68. A spring 610 is sleeved on the outer surface of the moving rod 60, and the two ends of the spring 610 are respectively fixedly connected to the piston disk 68 and the fixed cylinder 67.

[0024] Furthermore, the load-bearing mechanism also includes a lifting block 611 arranged in the movable shell 69, and a support block 612 is fixed to a side of the lifting block 611 away from the fixed cylinder 2 67, and the support block 612 is slidably connected to the inner wall of the belt conveyor 1.

[0025] The processed plastic hollow board is placed on the belt conveyor 1, and is transported by the belt conveyor 1 to a position where the manipulator 2 can pick it up. The vacuum suction head 3 is connected to the external pump body to generate suction at the vacuum suction head 3, and the vacuum suction head 3 is moved to the plastic hollow board by the manipulator 2. The plastic hollow board is sucked into the stacking box 4 by suction for stacking, which is convenient for transportation. This is the existing technology, so it will not be described in detail here.

[0026] Considering that in the prior art, a large number of plastic hollow boards are stacked layer by layer, the plastic hollow board at the bottom bears the weight of all the plastic hollow boards above, and as the stacking height increases, the pressure on the bottom plastic hollow board increases sharply, which can easily cause deformation, rupture and other damage to the bottom plastic hollow board. The following improvements are now made: Through the setting of the elastic plate 61, when the plastic hollow plate is sucked into the stacking box 4, it will fall on the elastic plate 61, and through the lifting rod 63 sliding in the liquid storage cylinder 62 and the elastic force of the spring 1 65, when the plastic hollow plates continue to be stacked, the pressure on the bottom plastic hollow plate can be initially buffered, and the bottom plastic hollow plate can be initially protected.

[0027] As the number of stacked plastic hollow plates increases, the pressure on the elastic plate 61 increases, which will push the lifting rod 63 and the piston plate 1 64 to slide downward in the liquid storage cylinder 62, compressing the spring 1 65. As the piston plate 1 64 slides, the liquid in the liquid storage cylinder 62 will be squeezed, and the liquid enters the fixed cylinder 2 67 through the hose 1 66. Since the piston plate 2 68 slides in the fixed cylinder 2 67, when the liquid enters the fixed cylinder 2 67, the piston plate 2 68 is pushed by the liquid and moves toward the middle of the stacking box 4. The piston plate 2 68 drives the moving rod 60, the moving shell 69 and the lifting block 611 to move together. The lifting block 611 drives the support block 612 to move from the inner cavity 5 to the middle of the stacking box 4 until the support block 612 moves from the inner cavity 5 to the stacking box 4.

[0028] A further advantage of adopting the above method is that when the support block 612 moves into the stacking box 4, the plastic hollow board that falls later can be supported by the support block 612, so that the plastic hollow board that falls later can be separated from the plastic hollow board that falls previously, thereby preventing the plastic hollow board that falls later from exerting greater pressure on the bottom plastic hollow board, which is beneficial to preventing the pressure on the bottom plastic hollow board from increasing sharply, causing deformation, rupture and other damage to the plastic hollow board.

[0029] Example 2, refer to Figure 1-Figure 8 A stacking system for processed plastic hollow plates, comprising a belt conveyor 1, a manipulator 2 is arranged on the side of the belt conveyor 1, a vacuum suction head 3 is installed on the manipulator 2, a stacking box 4 is also arranged on the side of the belt conveyor 1, and an inner cavity 5 is opened in the stacking box 4, and further comprising: The load-bearing mechanism is arranged in the belt conveyor 1. When the plastic hollow plates dropped into the belt conveyor 1 reach a predetermined weight, the load-bearing mechanism is used to apply pressure to the bottom plastic hollow plates. An adjusting mechanism 1 is installed on the load-bearing mechanism, and the adjusting mechanism 1 is used to apply pressure to the upper plastic hollow plate from both sides.

[0030] Furthermore, the adjustment mechanism 1 includes a vertical rod 71 fixed in the movable shell 69, and the lifting block 611 slides on the outer surface of the vertical rod 71. The outer surface of the vertical rod 71 is sleeved with a spring 3 72. The two ends of the spring 3 72 are respectively fixedly connected to the movable shell 69 and the lifting block 611. The side of the lifting block 611 is fixed with an extrusion rod 73, and the extrusion rod 73 is slidably connected to the inner wall of the movable shell 69.

[0031] Furthermore, the adjustment mechanism 1 also includes a fixed block 74 fixed on the top of the movable shell 69, a sliding rod 75 slides inside the fixed block 74, an arc block 76 is fixed to the end of the sliding rod 75 close to the fixed cylinder 2 67, the arc block 76 corresponds to the position of the extrusion rod 73, and a clamping plate 1 77 for applying pressure to the upper plastic hollow plate is fixed to the end of the sliding rod 75 away from the arc block 76, and a spring 4 78 is sleeved on the outer surface of the sliding rod 75, and the two ends of the spring 4 78 are respectively fixedly connected to the arc block 76 and the fixed block 74.

[0032] Considering that when the support block 612 is moved into the stacking box 4, the plastic hollow plates that fall later are stacked on the support block 612, the bottom plastic hollow plates on the top of the support block 612 will also be subjected to greater pressure, and there is still a possibility that some of the plastic hollow plates will be damaged. The following improvements are now made: When the plastic hollow plates on the support block 612 are continuously stacked, the lifting block 611 will be driven to slide downward on the outer surface of the vertical rod 71, squeezing the spring three 72, which is connected to the squeezing rod 73 through the lifting block 611. When the lifting block 611 moves downward, the squeezing rod 73 will also be driven to move downward. Since the position of the squeezing rod 73 corresponds to the position of the arc block 76, when the squeezing rod 73 drops to a certain position, the squeezing rod 73 will contact the arc block 76 and squeeze the arc block 76, thereby driving the arc block 76 and the sliding rod 75 to move toward the middle direction of the stacking box 4, pressurizing the spring four 78, and the sliding rod 75 drives the clamping plate 1 77 to move toward the middle direction of the stacking box 4, thereby clamping the plastic hollow plates stacked on the top layer of the support block 612 in the left and right directions.

[0033] A further advantage of adopting the above method is that when the plastic hollow plates on the support block 612 are stacked to a certain weight, pressure can be applied to the top layer of plastic hollow plates from the left and right directions to change the direction of force, thereby reducing the pressure on the bottom layer of plastic hollow plates stacked on the top of the support block 612, thereby again avoiding deformation, rupture and other damage to the plastic hollow plates.

[0034] Example 3, refer to Figure 1-Figure 8 A stacking system for processed plastic hollow plates, comprising a belt conveyor 1, a manipulator 2 is arranged on the side of the belt conveyor 1, a vacuum suction head 3 is installed on the manipulator 2, a stacking box 4 is also arranged on the side of the belt conveyor 1, and an inner cavity 5 is opened in the stacking box 4, and further comprising: The load-bearing mechanism is arranged in the belt conveyor 1. When the plastic hollow plates dropped into the belt conveyor 1 reach a predetermined weight, the load-bearing mechanism is used to apply pressure to the bottom plastic hollow plates. An adjusting mechanism 1 is installed on the load-bearing mechanism, and the adjusting mechanism 1 is used to apply pressure to the upper plastic hollow plate from both sides.

[0035] Furthermore, the belt conveyor 1 is also provided with an adjustment mechanism 2 for applying pressure to the upper plastic hollow plate from the front and rear sides. The adjustment mechanism 2 includes a rectangular rack 81 fixed on the arc block 76, and the rectangular rack 81 is slidably connected to the fixed block 74. The outer surface of the rectangular rack 81 is meshed with a gear 82, and a rotating rod 83 is fixed at the axis of the gear 82. A mounting block 84 is fixed on the top of the movable shell 69, and the rotating rod 83 is rotatably connected to the mounting block 84 through a bearing, and a connecting rope 85 is fixed to the outer surface of the rotating rod 83.

[0036] Furthermore, the second adjustment mechanism also includes a mounting groove 86 opened on the inner wall of the belt conveyor 1, a fixing rod 87 is fixed in the mounting groove 86, a clamping plate 88 is slidably provided on the outer surface of the fixing rod 87, the end of the connecting rope 85 away from the rotating rod 83 is fixedly connected to the clamping plate 88, a spring 5 89 is sleeved on the outer surface of the fixing rod 87, and the two ends of the spring 5 89 are respectively fixedly connected to the clamping plate 88 and the belt conveyor 1.

[0037] Considering that the pressure is only applied from the left and right directions to the top layer of the hollow plastic plates stacked on the support block 612, the clamping force is relatively small. When the number of stacked hollow plastic plates is large, the gravity of the hollow plastic plates will still be applied to the hollow plastic plates at the bottom layer of the support block 612, causing damage to the hollow plastic plates. The following improvements are now made: It is connected to the arc block 76 through the rectangular rack 81. When the arc block 76 is squeezed by the squeezing rod 73 and moves toward the middle of the stacking box 4, it will drive the rectangular rack 81 to move together. The rectangular rack 81 is meshed with the gear 82, thereby driving the gear 82 and the rotating rod 83 to rotate. The rotating rod 83 drives the connecting rope 85 to wrap around the outer surface of the rotating rod 83. Since the connecting rope 85 is connected to the clamping plate 88, the clamping plate 88 is driven to move on the outer surface of the fixing rod 87 toward the middle of the stacking box 4, squeezing the spring 5 89. Through the setting of the mounting groove 86, the clamping plate 88 and the fixing rod 87 will not affect the falling of the plastic hollow plate.

[0038] A further advantage of adopting the above method is that the top layer of the plastic hollow plate can be clamped from the front-to-back direction by two clamping plates 88, so that pressure can be applied to the top layer of the plastic hollow plate from the front-to-back direction, and by cooperating with the adjustment mechanism 1, the pressure on the bottom layer of the plastic hollow plate stacked on the top of the support block 612 can be further reduced, thereby further preventing the plastic hollow plate from being deformed or broken.

[0039] It should be noted that this design is used to facilitate the removal of the lower layer of plastic hollow boards, compared to the continuous use of support blocks 612 for support. When the support blocks 612 are moved into the stacking box 4, a certain distance is left between the support blocks 612 and the bottom layer of plastic hollow boards, so that the support blocks 612 can be easily settled due to the gravity of the plastic hollow boards.

[0040] Embodiment 4, referring to Figure 1-Figure 8 A stacking system for processed plastic hollow plates, comprising a belt conveyor 1, a manipulator 2 is arranged on the side of the belt conveyor 1, a vacuum suction head 3 is installed on the manipulator 2, a stacking box 4 is also arranged on the side of the belt conveyor 1, and an inner cavity 5 is opened in the stacking box 4, and further comprising: The load-bearing mechanism is arranged in the belt conveyor 1. When the plastic hollow plates dropped into the belt conveyor 1 reach a predetermined weight, the load-bearing mechanism is used to apply pressure to the bottom plastic hollow plates. An adjusting mechanism 1 is installed on the load-bearing mechanism, and the adjusting mechanism 1 is used to apply pressure to the upper plastic hollow plate from both sides.

[0041] Furthermore, both the clamping plate 2 88 and the clamping plate 1 77 are provided with auxiliary mechanisms for increasing the friction between the upper plastic hollow plate, the auxiliary mechanisms include an air cushion 91 fixed between the fixed block 74 and the arc block 76, the outer surface of the air cushion 91 is connected to a hose 2 92, the end of the hose 2 92 away from the air cushion 91 is respectively connected to the clamping plate 1 77 and the clamping plate 2 88, and the clamping plate 1 77 and the clamping plate 2 88 are both connected to air bags 93.

[0042] The air cushion 91 is fixed between the arc block 76 and the fixed block 74. When the arc block 76 is squeezed by the squeezing rod 73 and moves, the air cushion 91 is also squeezed. The squeezed gas enters the clamping plate 1 77 and the clamping plate 2 88 through the hose 2 92, and then enters the airbag 93 from the clamping plate 1 77 and the clamping plate 2 88, causing the airbag 93 to expand and bulge.

[0043] A further advantage of adopting the above method is that when the adjusting mechanism 1 and the adjusting mechanism 2 clamp and apply pressure to the top plastic hollow plate from the front and back and left and right directions, the airbags 93 on the clamping plate 1 77 and the clamping plate 2 88 can be inflated. When the plastic hollow plate falls and contacts the airbags 93, the friction between the plastic hollow plate and the clamping plate 1 77 and the clamping plate 2 88 can be increased, thereby improving stability and preventing the top plastic hollow plate from falling and contacting the plastic hollow plate on the support block 612, thereby applying pressure thereto, thereby further improving the protection performance of the plastic hollow plate.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
