Description

A conveying device for paper-plastic composite bag production Technical Field

[0001] This invention belongs to the field of paper-plastic composite bag production and conveying technology, and particularly relates to a paper-plastic composite bag production and conveying device. Background Technology

[0002] Paper-plastic composite bags are packaging bags made of paper and plastic materials. They are usually composed of two or more layers of different materials, combining the good printability and environmental protection of paper with the water resistance and abrasion resistance of plastic.

[0003] In the production process of paper-plastic composite bags, a conveyor device is needed to transport the bags to the next processing position. However, during the transport of paper-plastic composite bags, due to their light weight and smooth surface, insufficient friction coefficient between the conveyor belt and the bags may lead to slippage. Slippage can cause instability in the position of the bags during transport, and may even cause them to move slowly or stop on the conveyor belt. This is especially true when transporting bags on inclined or sloped conveyor lines, where the bags may slide backward, making transport impossible. To prevent slippage during transport, existing technologies use multiple baffles on the conveyor belt. However, this method requires manual placement of the bags within the space created by the baffles, which is cumbersome. Furthermore, too many baffles increase the load on the conveyor belt, reducing its lifespan and affecting performance.

[0004] Furthermore, if the speed of the conveyor belt is not matched to the movement speed of the paper-plastic composite bag, the paper-plastic composite bag may slip during the conveying process. If the conveyor belt speed is too fast, the bag may not be able to keep up, resulting in relative slippage, which will prevent the paper-plastic composite bag from being conveyed quickly and reduce the conveying efficiency of the conveying device.

[0005] Therefore, we propose a conveying device for the production of paper-plastic composite bags to solve the above problems. Summary of the Invention

[0006] The technical problem to be solved by this invention is that when conveying paper-plastic composite bags, due to the light weight and smooth surface of the paper-plastic composite bags, the insufficient coefficient of friction between the conveyor belt surface and the paper-plastic composite bags may lead to slippage. The slippage phenomenon will cause the position of the paper-plastic composite bags to be unstable during the conveying process, and may even cause the paper-plastic composite bags to move slowly or stop on the conveyor belt. Especially when it is necessary to transport paper-plastic composite bags on a slope or inclined conveyor line, the paper-plastic composite bags may slide backward, making it impossible to transport the paper-plastic composite bags.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By setting up an electrostatic generation component, when the paper-plastic composite bag needs to be transported to the next processing position, the upper tip of the friction metal plate contacts the outer wall of the conveyor belt, causing the conveyor belt to generate static electricity. After the static electricity is generated, the surface of the conveyor belt becomes charged. When the paper-plastic composite bag comes into contact with the charged conveyor belt, due to the interaction between the charges, an electrostatic adsorption phenomenon occurs, causing the paper-plastic composite bag to adhere to the surface of the conveyor belt. As the conveyor belt rotates, it follows and moves with it, preventing slippage and ensuring that the paper-plastic composite bag does not remain in place, thus facilitating stable transportation of the paper-plastic composite bag and improving the transportation efficiency of the device.

[0023] 2. By using the second and third transmission plates, spur gears, and fixed springs, when it is necessary to accelerate the conveying efficiency of paper-plastic composite bags, the conveyor belt can generate more static electricity, enabling stable adsorption and conveying of the paper-plastic composite bags. The contact area between the friction metal plate and the conveyor belt can be adjusted according to the conveying speed of the paper-plastic composite bags, increasing the electrostatic effect of the conveyor belt, facilitating stable adsorption of the paper-plastic composite bags, and preventing slippage between the paper-plastic composite bags and the conveyor belt when the conveying speed increases, which would affect the conveying of the paper-plastic composite bags and improve the stability and conveying efficiency of the device.

[0024] 3. The auxiliary unloading component can push the paper-plastic composite bags adhering to the conveyor belt to the next processing position, which facilitates more stable transportation of the paper-plastic composite bags. It can also make the connecting rod drive the conductive plate to contact the surface of the conveyor belt, and conduct away the static electricity on the surface of the conveyor belt through the external ground wire, so that the pusher shell can better push the paper-plastic composite bags to the next processing position, thereby improving the transportation efficiency and reliability of the device.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Referring to Figures 1-7, a conveying device for paper-plastic composite bag production includes a conveyor frame 1. A servo motor 2 is fixedly connected to one side wall of the conveyor frame 1. The same driving roller 3 is rotatably connected to the inner walls of both ends of the conveyor frame 1. The output end of the servo motor 2 passes through the side wall of the conveyor frame 1 and is fixedly connected to the side wall of the driving roller 3. The same driven roller 4 is rotatably connected to the inner walls of both ends of the conveyor frame 1. The same conveyor belt 5 is rotatably sleeved on the outer walls of the driven roller 4 and the driving roller 3. Multiple support rollers 6 are rotatably connected to the inner walls of both ends of the conveyor frame 1. The outer walls of the multiple support rollers 6 all abut against the inner wall of the conveyor belt 5.

[0035] A static electricity generating component 7 is fixedly connected to one side wall of the conveyor frame 1, and auxiliary unloading components 8 are symmetrically fixedly connected to the side walls of both ends of the conveyor frame 1.

[0036] In this embodiment, the static electricity generating component 7 includes a housing 71 fixedly connected to one side wall of the conveyor frame 1, a round rod 73 rotatably connected to one inner wall of the conveyor frame 1, one end of the round rod 73 passing through the side wall of the conveyor frame 1 and rotatably connected to the inner wall of the housing 71, a rotating rod 72 rotatably connected to one inner wall of the housing 71, one end of the rotating rod 72 passing through the side wall of the conveyor frame 1 and fixedly connected to one end of the drive roller 3, pulleys 74 are fixedly sleeved on the rod walls of both the round rod 73 and the rotating rod 72, the same transmission belt 75 is rotatably sleeved on the outer walls of the two pulleys 74, and a self-adjusting drive shell 76 is fixedly sleeved on the rod wall of the round rod 73;

[0037] The rod 73 is located inside the self-adjusting drive housing 76. Multiple first transmission housings 77 are arranged in a ring on the rod wall. A first spring 78 is fixedly connected to the bottom inner wall of the first transmission housing 77. A first transmission plate 79 is fixedly connected to one end of the first spring 78.

[0038] The rod 73 is located in the self-adjusting drive housing 76. Multiple second transmission housings 710 are arranged in a ring on the rod wall. A second spring 711 is fixedly connected to the bottom inner wall of the multiple second transmission housings 710. A second transmission plate 712 is fixedly connected to one end of the second spring 711.

[0039] The rod 73 is located inside the self-adjusting drive housing 76. Multiple third transmission housings 713 are arranged in a ring on the rod wall. A third spring 714 is fixedly connected to the bottom inner wall of the third transmission housing 713. A third transmission plate 715 is fixedly connected to one end of the third spring 714.

[0040] The side walls of the first transmission housing 77, the second transmission housing 710, the third transmission housing 713, and the self-adjusting drive housing 76 are all provided with openings for the first transmission plate 79, the second transmission plate 712, and the third transmission plate 715 to extend out. The elastic coefficients of the first spring 78, the second spring 711, and the third spring 714 increase significantly from small to large. The lengths of the first transmission plate 79, the second transmission plate 712, and the third transmission plate 715 increase significantly from small to large.

[0041] Specifically, when it is necessary to accelerate the conveying efficiency of paper-plastic composite bags, the conveyor belt 5 can generate more static electricity to stably adsorb and convey the paper-plastic composite bags. The contact area between the friction metal plate 721 and the conveyor belt 5 can be adjusted according to the conveying speed of the paper-plastic composite bags, thereby increasing the electrostatic effect of the conveyor belt 5, facilitating stable adsorption of the paper-plastic composite bags, preventing slippage between the paper-plastic composite bags and the conveyor belt 5 when the conveying speed increases, which would affect the conveying of the paper-plastic composite bags, and improving the stability and conveying efficiency of the device when conveying paper-plastic composite bags.

[0042] In this embodiment, the inner walls of both ends of the conveyor frame 1 are rotatably connected to the same threaded screw 716. The rod wall of the threaded screw 716 is fixedly sleeved with a spur gear 717. The rack of the spur gear 717 is arc-shaped. The spur gear 717 can mesh with the first transmission plate 79, the second transmission plate 712 and the third transmission plate 715 when they are extended. The rod wall of the threaded screw 716 is rotatably connected to a movable plate 718. A fixed spring 719 is fixedly connected to one side wall of the movable plate 718. One end of the fixed spring 719 is fixedly connected to the inner wall of the conveyor frame 1. The fixed spring 719 is located on the outer wall of the threaded screw 716.

[0043] Two connecting plates 720 are symmetrically fixedly sleeved on the rod wall of the threaded screw 716. The same friction metal plate 721 is fixedly connected to one side wall of the two connecting plates 720. The cross-sectional shape of the friction metal plate 721 is elliptical. The same limiting rod 722 is fixedly connected to the inner walls of both ends of the conveying frame 1. The side wall of the moving plate 718 is provided with a sliding groove that matches the limiting rod 722.

[0044] Specifically, when the paper-plastic composite bag needs to be transported to the next processing position during production, the upper vertex of the friction metal plate 721 contacts the outer wall of the conveyor belt 5, causing the conveyor belt 5 to generate static electricity. After the static electricity is generated, the surface of the conveyor belt 5 carries a charge. When the paper-plastic composite bag comes into contact with the charged conveyor belt 5, due to the interaction between the charges, an electrostatic adsorption phenomenon occurs, causing the paper-plastic composite bag to adhere to the surface of the conveyor belt 5. As the conveyor belt 5 rotates, it follows and moves, preventing slippage and preventing the paper-plastic composite bag from staying in place and being unable to be effectively transported. This facilitates stable transportation of the paper-plastic composite bag and improves the transportation efficiency of the device.

[0045] In this embodiment, the auxiliary unloading assembly 8 includes two fixed shells 81 symmetrically fixedly connected to the side walls of both ends of the conveyor frame 1. A side rod 82 is rotatably connected to the inner wall of one end of each fixed shell 81. One end of the side rod 82 passes through the side wall of the conveyor frame 1 and is fixedly connected to one end of the driven roller 4. A worm gear 83 is fixedly sleeved on the rod wall of the side rod 82. The same first reciprocating screw 84 is rotatably connected to the inner walls of both ends of the two fixed shells 81. A worm wheel 822 is fixedly sleeved on the rod wall of the first reciprocating screw 84. The worm wheel 822 meshes with the worm gear 83. A movable slider 85 is rotatably connected to the rod wall of the first reciprocating screw 84. A strip-shaped opening is provided on the upper side wall of the fixed shell 81 for the movable slider 85 to move.

[0046] A transmission gear plate 86 is fixedly connected to the upper side wall of the movable slider 85. Two support rods 87 are symmetrically rotatably connected to the top side wall of the conveyor frame 1. A side gear 88 is fixedly sleeved on the rod wall of the support rod 87. The side gear 88 meshes with the corresponding transmission gear plate 86. A pusher shell 89 is fixedly connected to the upper end of each support rod 87. The same second reciprocating screw 810 is rotatably connected to the inner walls of both ends of the pusher shell 89. A rubber gear 811 is fixedly sleeved on the rod wall of the second reciprocating screw 810. An opening is provided on the side wall of the pusher shell 89 for the rubber gear 811 to rotate.

[0047] Two sector-shaped toothed plates 812 are symmetrically fixedly connected to the top side wall of the conveyor frame 1. The sector-shaped toothed plates 812 mesh with the corresponding rubber gears 811. The rod wall of the second reciprocating screw 810 is threadedly connected to a push plate 813. A push rod 814 is fixedly connected to the side wall of one end of the push plate 813. A sealing shell 815 is fixedly connected to the inner wall of one end of the push shell 89. A sealing piston 816 is movably sealed to the inner wall of the sealing shell 815. One end of the push rod 814 passes through the side wall of the sealing shell 815 and is fixedly connected to the side wall of the sealing piston 816.

[0048] Two sleeves 817 are symmetrically fixedly connected to the inner walls of both ends of the pusher shell 89. A movable piston 818 is moved and sealed inside the two sleeves 817. A connecting rod 819 is fixedly connected to the bottom side wall of the movable piston 818. One end of the two connecting rods 819 passes through the side wall of the pusher shell 89 and is fixedly connected to a conductive plate 820. The side wall of each sleeve 817 is provided with a through hole, and a connecting pipe 821 is fixedly sleeved inside the corresponding through hole. One end of the connecting pipe 821 extends inward through the side wall of the sealing shell 815. The side wall of the conductive plate 820 is provided with an external ground wire.

[0049] Specifically, it can push the paper-plastic composite bag adhering to the conveyor belt 5 to the next processing position, which facilitates more stable transportation of the paper-plastic composite bag. It can also make the connecting rod 819 drive the conductive plate 820 to contact the surface of the conveyor belt 5, and conduct away the static electricity on the surface of the conveyor belt 5 through the external ground wire, so that the pusher shell 89 can better push the paper-plastic composite bag to the next processing position, thereby improving the transportation efficiency and reliability of the device.

[0050] The operating principle of the present invention is described as follows:

[0051] In this invention, when the paper-plastic composite bag needs to be transported to the next processing position during production, the servo motor 2 is started, driving the drive roller 3 to rotate. Under the transmission action of the conveyor belt 5, the driven roller 4 rotates accordingly, ensuring the stable rotation of the conveyor belt 5. The paper-plastic composite bag to be transported is placed on the conveyor belt 5 for transport. During the rotation of the drive roller 3, since the rotation speed of the drive roller 3 represents the transport speed of the paper-plastic composite bag, it will drive the rotating rod 72 to rotate synchronously with the transport speed of the paper-plastic composite bag, causing the pulley 74 to rotate accordingly. Under the transmission action of the transmission belt 75, the round rod 73 rotates synchronously. During the rotation of the round rod 73, multiple first transmission shells 77 and second transmission shells 7... 10 and the third transmission housing 713 rotate together. Since the rotation speed of the round rod 73 is proportional to the rotation speed of the conveyor belt 5, when the speed of the conveyor belt 5 increases, the paper-plastic composite bag is prone to slippage between itself and the conveyor belt 5, affecting the conveying of the paper-plastic composite bag. However, at this time, the round rod 73 also accelerates. Under the action of centrifugal force, since the elastic coefficient of the first spring 78 is smaller than that of the second spring 711 and the third spring 714, the first spring 78 will first throw out the first transmission plate 79, which extends out from the self-adjusting drive housing 76 and meshes with the spur gear 717. At this time, as the round rod 73 rotates, the first transmission plate 79 will rotate, driving the spur gear 717 to rotate, thereby causing the threaded screw 716 to rotate. The movable plate 718 moves to one end, compressing the fixed spring 719. When the fixed spring 719 is compressed to a certain extent, the required force to press the fixed spring 719 increases, at which point the movable plate 718 can no longer move, and the threaded screw 716 stops rotating. At this time, the first transmission plate 79 continuously meshes with the teeth of the spur gear 717. However, because the force required for the spur gear 717 to rotate has increased, the contact area between the first transmission plate 79 and the teeth of the spur gear 717 is small, resulting in low friction. Consequently, the first transmission plate 79 cannot drive the spur gear 717 to rotate. During the meshing process with the spur gear 717, as the first transmission plate 79 continues to rotate and contact the teeth of the spur gear 717, it will push the first transmission plate 79 towards the first... The compression within the transmission housing 77 does not affect the rotation of the first transmission plate 79, and the first transmission plate 79 will continuously contact the teeth of the spur gear 717. At this time, the spur gear 717 will not rotate in the opposite direction. When the spur gear 717 rotates, it drives the threaded screw 716 to rotate, which will cause the connecting plate 720 and the friction metal plate 721 to rotate. At this time, the upper vertex of the friction metal plate 721 will contact the outer wall of the conveyor belt 5, causing the conveyor belt 5 to continuously rub against the friction metal plate 721. When the metal plate contacts and rubs against the surface of the conveyor belt 5, electrons may transfer from one material to the other, causing them to carry opposite charges, thus generating static electricity on the conveyor belt 5. After static electricity is generated, the surface of the conveyor belt 5 carries a charge.When the paper-plastic composite bag comes into contact with the charged conveyor belt 5, electrostatic adsorption occurs due to the interaction between the charges. This causes the paper-plastic composite bag to adhere to the surface of the conveyor belt 5 and move with it as the belt rotates, preventing slippage and ensuring the bag stays in place. This facilitates stable transport of the paper-plastic composite bag and improves the transport efficiency of the device.

[0052] When it is necessary to accelerate the conveying efficiency of paper-plastic composite bags, the speed of the servo motor 2 is controlled to increase the rotation speed of the conveyor belt 5. At this time, the rotation speed of the drive roller 3 increases, and the rotation speed of the rod 73 increases accordingly. The second transmission housing 710 rotates accordingly, increasing centrifugal force. The second spring 711 drives the second transmission plate 712 to extend. Since the second transmission plate 712 is longer than the first transmission plate 79, and the first spring 78, the second spring 711, and the third spring 714 can extend to the same length, the contact area with the teeth of the circular gear 717 increases, increasing friction. The increased force drives the sprocket 717 to rotate, causing the threaded screw 716 to continue rotating, which in turn moves the movable plate 718, compressing the fixed spring 719. As the fixed spring 719 is compressed, the force required to press it increases. At this point, the movable plate 718 can no longer move, the sprocket 717 cannot rotate, and the second transmission plate 712, after contacting the teeth of the sprocket 717, is pressed into the second transmission housing 710. When the sprocket 717 rotates, it drives the friction metal plate 721 to rotate, causing the top two side walls of the friction metal plate 721 to... The position contacts the outer wall of the conveyor belt 5, increasing the contact area and generating more static electricity. This increases the adhesion between the conveyor belt 5 and the paper-plastic composite bag, allowing for more stable transport. When the conveying speed of the paper-plastic composite bag needs to be increased again, the principle is the same: the third spring 714 extends the third transmission plate 715. The longer length of the third transmission plate 715 increases the contact area with the teeth of the sprocket 717, increasing friction and driving the sprocket 717 to continue rotating. This causes the top sides of the friction metal plate 721 to contact the conveyor belt 5. The increased contact area between the two belts allows the conveyor belt 5 to generate more static electricity, enabling stable adsorption and conveying of the paper-plastic composite bag. The contact area between the friction metal plate 721 and the conveyor belt 5 can be adjusted according to the conveying speed of the paper-plastic composite bag, increasing the electrostatic effect of the conveyor belt 5. This facilitates stable adsorption of the paper-plastic composite bag and prevents slippage between the paper-plastic composite bag and the conveyor belt 5 when the conveying speed increases, which would affect the conveying of the paper-plastic composite bag and improve the stability and conveying efficiency of the device.

[0053] During the rotation of the driven roller 4, the side rod 82 rotates accordingly, causing the worm gear 83 to drive the meshing worm wheel 822 to rotate as well. The rotation of the worm wheel 822 drives the first reciprocating screw 84 to rotate, causing the moving slider 85 to reciprocate, which in turn drives the transmission gear plate 86 to move. During the movement of the transmission gear plate 86, the side gear 88 meshing with it rotates, driving the support rod 87 to rotate. This achieves the reciprocating movement of the pusher shell 89 around the support rod 87, pushing the paper-plastic composite bag adhered to the conveyor belt 5 to the next processing position, facilitating more stable conveying of the paper-plastic composite bag. Furthermore, during the reciprocating movement of the pusher shell 89, the rubber gear 811 moves accordingly. At this time, due to the fan-shaped gear plate... With 812 stationary, as the rubber gear 811 moves, the meshing of the rubber gear 811 with the sector tooth plate 812 causes the rubber gear 811 to rotate, which in turn drives the second reciprocating screw 810 to rotate. This causes the push plate 813 to drive the push rod 814 to move reciprocally, pushing the sealing piston 816 into one end of the sealing shell 815. This compresses the air inside the sealing shell 815 and delivers it to the two sleeves 817 through the connecting pipe 821. This, in turn, pushes the moving piston 818 downward, causing the connecting rod 819 to drive the conductive plate 820 to contact the surface of the conveyor belt 5. The static electricity on the surface of the conveyor belt 5 is then conducted away through the external ground wire, allowing the pusher shell 89 to better push the paper-plastic composite bag to the next processing position, thus improving the transportation efficiency and reliability of the device.
