Description

Technical Field

[0001] This application relates to the field of plastic film recycling equipment technology, and in particular to a recycling and reuse equipment for waste plastic film from color printing. Background Technology

[0002] Waste plastic film from color printing typically refers to ink-stained scraps and defective products generated during the production process of printing and packaging plants. The recycling of waste plastic film from color printing includes pretreatment, crushing, chemical cleaning (deinking), washing, dehydration and drying, and granulation. During washing, a pusher-type washing tank is generally used to clean the crushed plastic film fragments.

[0003] A push-type film washing tank generally includes a tank body, a push mechanism (including a main shaft and blades), a drive mechanism (including a motor, flywheel, and chain), and a lifting device. In use, the crushed and de-inked waste plastic film from color printing enters the tank body. The push mechanism pushes the waste plastic film for washing and moves it toward the lifting mechanism on the tank body. The waste plastic film that reaches the lifting mechanism is discharged from the lifting mechanism.

[0004] During the cleaning process, long strips or large pieces of waste printed plastic film easily get tangled on the blades, increasing the motor load and causing prolonged tangling to exacerbate equipment wear. Furthermore, the density of the broken waste printed plastic film fragments is close to or less than that of water, causing them to float on the water surface. Although the plastic film fragments located on the blades are pushed into the water for cleaning, the plastic film fragments between two adjacent blades will still float on the water surface. During the conveying process, the agitation and friction of the floating plastic film fragments are limited, making it difficult to effectively remove impurities from the plastic film fragments. Summary of the Invention

[0005] This application proposes a recycling and reuse equipment for waste plastic film from color printing, which has the advantages of automatically cleaning plastic film wrapped around the blades and enhancing the cleaning of plastic film by immersing it in water, thereby solving the problems of increased equipment wear caused by plastic film wrapping around the blades and the difficulty in cleaning impurities caused by plastic film floating on the water surface.

[0006] To achieve the above objectives, this application adopts the following technical solution: a recycling and reuse processing device for waste plastic film from color printing, comprising a tank, a pushing mechanism, a driving mechanism, and a lifting device. The pushing mechanism includes a support base, a main shaft, and blades. The blades include vertical blades and horizontal blades. The driving mechanism includes a motor, a flywheel, and a chain. The blades are provided with an anti-winding mechanism, which includes: a guide block, fixedly installed on the inner wall of the tank and movably sleeved on the end of the main shaft. Guide grooves are respectively opened on the opposite side walls of the guide block. The guide grooves are cam-shaped, and the protrusions face upwards. A pushing ring is movably sleeved on the outer side of the blade, and its inner wall is tightly attached to the outer wall of the horizontal blade. The two ends of the pushing ring are movably inserted into the guide grooves of the two end guide blocks.

[0007] Furthermore, the cross-section of the pusher ring is an isosceles trapezoid, and the side of the pusher ring that is in close contact with the blade is the long base side.

[0008] Furthermore, the maximum distance between the guide groove and the main shaft axis is greater than the maximum distance between the blade and the main shaft axis, and the minimum distance between the guide groove and the main shaft axis is less than the minimum distance between the blade and the main shaft axis.

[0009] Furthermore, the immersion mechanism between the two pushing mechanisms includes: a connecting rod comprising several vertical rods and a horizontal rod, wherein the vertical rods are equidistantly mounted on the horizontal rod, the connecting rod is located directly below the main shaft, the top end of each vertical rod is inserted into a guide groove of a guide block, and the upper end face of each vertical rod is inclined; an immersion plate is fixedly connected to the horizontal rod between two adjacent vertical rods, the height of the immersion plate being flush with the liquid level in the tank; a support rod is fixedly mounted on both sides of the inner wall of the tank; and several support springs are equidistantly disposed between the support rod and the connecting rod, with both ends fixedly connected to the horizontal rods of the support rod and the connecting rod, respectively.

[0010] Furthermore, baffles are fixedly installed on the top of the immersion plate and on both sides near the main shaft. The baffles are inclined and the two ends of the immersion plate are in close contact with the inner wall of the tank.

[0011] Furthermore, the supporting spring is always in a compressed state, and several limiting blocks are fixedly installed on both sides of the inner wall of the groove, with the limiting blocks positioned above the crossbar of the connecting rod.

[0012] Furthermore, a disturbance mechanism is provided at the lower part of the inside of the tank. The disturbance mechanism includes: a rotating shaft, with both ends fixedly connected to the inner wall of the tank; a power shaft, with both ends fixedly connected to the crossbar of the connecting rod; and a disturbance plate, with one end movably sleeved on the rotating shaft and the other end having an elongated hole, which is movably sleeved on the power shaft.

[0013] Furthermore, the disturbance mechanism also includes: several through holes, which are stepped shafts formed on the disturbance plate; a cover plate, which is located at the position with a larger diameter of the through holes, and a hinge shaft is inserted into the side of the cover plate near the upper end of the disturbance plate, and the two ends of the hinge shaft are fixedly connected to the inner wall of the through holes.

[0014] Furthermore, a permanent magnet ring is embedded in the stepped part of the through hole, and a permanent magnet block is embedded in the lower end face of the cover plate. The permanent magnet ring embedded in the through hole and the permanent magnet block in the cover plate generate a magnetic force that attracts each other.

[0015] This application has the following beneficial effects: 1. The present application provides a recycling and reuse processing device for waste plastic film from color printing. When the blades rotate with the main shaft, they drive the pusher ring to rotate synchronously, so that the pusher ring slides in the guide groove of the guide block, thereby enabling the pusher ring to reciprocate on the blades. The reciprocating pusher ring cuts and pushes the plastic film wrapped on the blades, thereby automatically cleaning the plastic film wrapped on the blades and preventing the plastic film wrapped on the blades from causing accelerated wear of the equipment.

[0016] 2. The recycling and reuse equipment for waste plastic film from color printing provided in this application intermittently pushes the connecting rod when the pusher ring slides in the guide groove of the guide block, so that the connecting rod drives the dip plate to move, thereby pushing the plastic film fragments between the two blades to move underwater. The dip plate drives the plastic film fragments to move in the water, which enhances the cleaning of the plastic film fragments and prevents the plastic film fragments from floating to the water surface and making it difficult to clean impurities.

[0017] 3. The recycling and reuse equipment for waste plastic film from color printing provided in this application, when the connecting rod is pushed by the blade, the power shaft is moved synchronously. The moving power shaft drives the disturbance plate to rotate around the rotating shaft. When the disturbance plate rotates upward, it pushes the water flow in the tank and the underwater plastic film fragments towards the lifting device, thus strengthening the movement of the underwater plastic film fragments. When the disturbance plate rotates downward, it pushes part of the water flow away from the lifting device, while the other part of the water flow continues to flow through the through hole, thus strengthening the turbulent state of the water flow in the tank and thereby enhancing the cleaning effect on the underwater plastic film fragments.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figures 1-7A recycling and reuse equipment for waste plastic film from color printing includes a tank 1, a pushing mechanism, a driving mechanism, and a lifting device 4. The upper end of the tank 1 is provided with several sets of equidistantly installed pushing mechanisms. Each pushing mechanism includes two support seats 21, a main shaft 22, and two blades 23. The two support seats 21 are symmetrically installed on both sides of the top of the tank 1. The two ends of the main shaft 22 are respectively movably inserted into the support seats 21 on both sides. Two blades 23 arranged in a circular array are fixedly installed on the main shaft 22 between the two support seats 21. Each blade 23 includes several vertical blades and one... A horizontal plate and several vertical plates are arranged in parallel and fixedly connected to the main shaft 22. The horizontal plate is arranged in parallel with the main shaft 22 and fixedly connected to several vertical plates. The driving mechanism includes a motor 31, a flywheel 32 and a chain 33. The motor 31 is fixedly installed on the side wall of one end of the tank 1. The flywheel 32 is fixedly sleeved on the output shaft of the motor 31. Two flywheels 32 are fixedly sleeved on one end of each support 21. Two adjacent flywheels 32 are connected by a chain 33. A lifting device 4 is fixedly installed at the upper end of the other end of the tank 1. The lifting device 4 is used to discharge the plastic film fragments after cleaning.

[0023] The blade 23 is equipped with an anti-winding mechanism for automatically cleaning up the wrapped plastic film. The anti-winding mechanism includes a guide block 51, a guide groove 52, and a pusher ring 53. The guide block 51 is fixedly installed on the inner wall of the groove 1 and is movably sleeved on the end of the main shaft 22. Each guide block 51 is fixedly connected to the support seat 21. The two guide blocks 51 are respectively provided with guide grooves 52 on their opposite side walls. The guide grooves 52 are cam-shaped and the protrusions face upward. The pusher ring 53 is movably sleeved on the outer side of the blade 23. The inner wall of the pusher ring 53 is close to the outer wall of the blade 23. The two ends of the pusher ring 53 are movably inserted into the guide grooves 52 of the guide blocks 51 at both ends. The cross section of the pusher ring 53 is an isosceles trapezoid, and the side of the pusher ring 53 that is close to the blade 23 is the long bottom side.

[0024] The maximum distance between the guide groove 52 and the axis of the main shaft 22 is greater than the maximum distance between the cross blade of the blade 23 and the axis of the main shaft 22, and the minimum distance between the guide groove 52 and the axis of the main shaft 22 is less than the minimum distance between the cross blade of the blade 23 and the axis of the main shaft 22. When the end of the pusher ring 53 slides in the guide groove 52, the pusher ring 53 moves back and forth on the blade 23. The reciprocating pusher ring 53 can push the plastic film fragments on the cross blade of the blade 23, so that the plastic film fragments cross the cross blade of the blade 23 and fall off the blade 23. Moreover, the plastic film fragments wrapped on the cross blade of the blade 23 are sheared by the pusher ring 53 and the cross blade of the blade 23, so that the plastic film fragments are broken and thus fall off the blade 23.

[0025] When using a pusher-type washing tank to clean plastic film fragments, the tank 1 is filled with clean water and the material is fed from the end away from the lifting device 4. At the same time, the output shaft of the motor 31 drives the main shaft 22 and the blades 23 to rotate through the transmission of the flywheel 32 and the chain 33. The rotating blades 23 agitate the plastic film fragments in the tank 1, causing the plastic film fragments to be conveyed to one end of the lifting device 4. Meanwhile, the mechanical action of the blades 23 causes the plastic film fragments to undergo continuous relative motion and friction in the water medium. With the help of the carrying and separation effect of the water flow, the dirt and impurities of the plastic film fragments are peeled off and removed. As the blade 23 rotates with the main shaft 22, the blade 23 drives the pusher ring 53 to rotate synchronously around the main shaft 22. The two ends of the pusher ring 53, which rotates with the blade 23, slide in the guide groove 52 of the guide block 51. Since the guide groove 52 is cam-shaped, the distance between the pusher ring 53, which slides in the guide groove 52, and the axis of the main shaft 22 will change, so that the pusher ring 53 can reciprocate on the blade 23. The reciprocating pusher ring 53 cuts and pushes the plastic film fragments wrapped on the blade 23, thereby automatically cleaning the plastic film wrapped on the blade 23 and preventing the plastic film wrapped on the blade from causing increased wear of the equipment.

[0026] A dipping mechanism for immersing plastic film fragments is provided between the two pushing mechanisms. The dipping mechanism includes a connecting rod 61, a dipping plate 62, a support rod 63, and a support spring 64. The connecting rod 61 includes several vertical rods and a horizontal rod. The vertical rods are equidistantly mounted on the horizontal rod. The connecting rod 61 is located below the guide block 51, and the vertical rods of the connecting rod 61 are directly below the main shaft 22. The top of the vertical rod is inserted into the guide groove 52 of the guide block 51. The upper end face of the vertical rod is inclined. When the end of the pushing ring 53 slides within the guide groove 52, it can... The inclined surface at the upper end of the vertical rod is sufficient to push the vertical rod. A dipping plate 62 is fixedly connected to the horizontal bar between two adjacent vertical rods. The dipping plate 62 is set horizontally and its height is flush with the height of the liquid level in the tank 1. Support rods 63 are fixedly installed on both sides of the inner wall of the tank 1. Several support springs 64 are installed at equal intervals on the top of the support rods 63. The top of the support springs 64 is fixedly connected to the bottom of the horizontal bar of the connecting rod 61. In order to prevent plastic film fragments in the tank 1 from getting tangled on the support springs 64, a sealing bag can be fitted on the outside of the support springs 64.

[0027] During equipment operation, the pusher ring 53 rotates with the main shaft 22 and the blades 23, and the end of the pusher ring 53 slides in the guide groove 52 of the guide block 51. When the end of the pusher ring 53 passes the bottom of the guide groove 52, the end of the pusher ring 53 presses against the vertical rod of the connecting rod 61 inserted in the guide groove 52, causing the connecting rod 61 to move downward as a whole. The downward-moving connecting rod 61 drives the dip plate 62 to move downward, thereby causing the dip plate 62 to push the plastic film fragments between the two blades 23 to move underwater. When the end of the pusher ring 53 passes the inclined surface at the top of the vertical rod of the connecting rod 61, the elastic force of the compressed support spring 64 pushes the connecting rod 61 and the dip plate 62 to reset, and the plastic film fragments move upward under the action of buoyancy. After the above cycle operation, the plastic film fragments move up and down while moving towards the lifting device 4, which strengthens the friction and collision between the plastic film fragments, thereby strengthening the cleaning of the plastic film fragments and preventing the plastic film fragments from floating to the water surface and making it difficult to clean impurities.

[0028] A baffle plate 621 is fixedly installed on the top of the immersion plate 62 and on both sides near the main shaft 22. The baffle plate 621 is inclined and the top of the baffle plate 621 faces the middle of the immersion plate 62. The two ends of the immersion plate 62 are in close contact with the inner wall of the tank 1. When the end of the pusher ring 53 slides in the guide groove 52, the pusher ring 53 squeezes the inclined surface of the upper end of the vertical rod of the connecting rod 61, causing the connecting rod 61 to drive the immersion plate 62 to move down. The immersion plate 62, which moves down to the water surface, presses down on the floating plastic film fragments, causing the plastic film fragments to be immersed in the water. The top of the baffle plate 621 on both sides of the immersion plate 62 is always higher than the liquid surface to prevent the plastic film fragments from entering the upper end of the immersion plate 62.

[0029] The support spring 64 is always in a compressed state. Several limiting blocks 65 are fixedly installed on both sides of the inner wall of the tank 1. The limiting blocks 65 are located above the horizontal bar of the connecting rod 61. When the end of the push ring 53 slides in the guide groove 52, the push ring 53 squeezes the inclined surface at the upper end of the vertical bar of the connecting rod 61, causing the connecting rod 61 to drive the immersion plate 62 to move down. When the end of the push ring 53 passes the inclined surface at the upper end of the vertical bar of the connecting rod 61, the elastic force of the compressed support spring 64 pushes the connecting rod 61 and the immersion plate 62 to reset. The limiting blocks 65 limit the connecting rod 61 to prevent the connecting rod 61 from moving up too much, causing the inclined surface at the upper end of the vertical bar of the connecting rod 61 to hit the inner wall of the guide groove 52.

[0030] A disturbance mechanism for agitating the water flow inside the tank 1 is provided at a lower position. The disturbance mechanism includes a rotating shaft 71, a power shaft 72, and a disturbance plate 73. The two ends of the rotating shaft 71 are fixedly connected to the inner wall of the tank 1, and the rotating shaft 71 is located directly below the main shaft 22. The position of the rotating shaft 71 is lower than the position of the crossbar of the connecting rod 61. The two ends of the power shaft 72 are fixedly connected to the crossbar of the connecting rod 61. The disturbance plate 73 is movably sleeved on the rotating shaft 71. The other end of the disturbance plate 73 has an elongated hole 731, which is movably sleeved on the power shaft 72. The upper end face of the disturbance plate 73 faces the lifting device 4. In order to prevent plastic film fragments from getting tangled on the power shaft 72, the power shaft 72 can be set as a two-section type. The two sections of the power shaft 72 are fixedly installed on the crossbar of the connecting rod 61, and the two sides of the power shaft 72 are movably placed in the elongated hole 731 of the disturbance plate 73. The disturbance mechanism also includes through holes 74 and cover plates 75. Several arrayed through holes 74 are provided on the disturbance plate 73. The through holes 74 are stepped shaft-shaped. A cover plate 75 is provided at the position of the larger diameter of the through hole 74. A hinge shaft is inserted into the side of the cover plate 75 near the upper end of the disturbance plate 73. The two ends of the hinge shaft are fixedly connected to the inner wall of the through hole 74.

[0031] During equipment operation, the pusher ring 53 rotates with the main shaft 22 and the blade 23, and the end of the pusher ring 53 slides in the guide groove 52 of the guide block 51. When the end of the pusher ring 53 passes the bottom of the guide groove 52, the end of the pusher ring 53 presses against the vertical rod of the connecting rod 61 inserted in the guide groove 52, causing the connecting rod 61 to move downward as a whole. The downward-moving connecting rod 61 drives the power shaft 72 to move downward. The downward-moving power shaft 72 pushes the elongated hole 731 of the disturbance plate 73, causing the disturbance plate 73 to rotate around the rotation axis 71. Due to the resistance of the water flow, part of the water flow is pushed by the disturbance plate 73, and the other part of the water flow passes through the through hole 74 and pushes the cover plate 7. 5. Pushing open the through hole 74 and passing over the disturbance plate 73, the turbulence of the water flow in the tank 1 is enhanced, thereby improving the cleaning effect on the underwater plastic film fragments. When the end of the pusher ring 53 passes over the inclined surface at the upper end of the vertical rod of the connecting rod 61, the elastic force of the compressed support spring 64 pushes the connecting rod 61 and the power shaft 72 to return to their original position. The upward-moving power shaft 72 pushes the elongated hole 731 of the disturbance plate 73, causing the disturbance plate 73 to rotate upward around the rotating shaft 71. The upward-rotating disturbance plate 73 pushes the water flow above the disturbance plate 73, causing the disturbance plate 73 to push the water flow in the tank 1 and the underwater plastic film fragments towards the lifting device 4, thus enhancing the movement of the underwater plastic film fragments.

[0032] A permanent magnet ring is embedded in the stepped part of the through hole 74, and a permanent magnet block is embedded in the lower end face of the cover plate 75. The permanent magnet ring embedded in the through hole 74 and the permanent magnet block in the cover plate 75 generate a magnetic force that attracts each other. When the downward rotating disturbance plate 73 is resisted by the water flow, part of the water flow is pushed by the disturbance plate 73, and the other part of the water flow pushes the cover plate 75 open through the through hole 74. At this time, the permanent magnet ring embedded in the through hole 74 and the permanent magnet block in the cover plate 75 generate a magnetic force that attracts each other, preventing the cover plate 75 from opening too wide. When the disturbance plate 73 stops rotating, the permanent magnet ring embedded in the through hole 74 and the permanent magnet block in the cover plate 75 generate a magnetic force that attracts each other, causing the cover plate 75 to return to its original position.

[0033] The working principle of this invention is as follows: Please see Figures 1-7 When using a push-type washing tank to clean plastic film fragments, the tank 1 is filled with clean water and the material is fed from the end away from the lifting device 4. At the same time, the output shaft of the motor 31 drives the main shaft 22 and the blades 23 to rotate through the transmission of the flywheel 32 and the chain 33. The rotating blades 23 agitate the plastic film fragments in the tank 1, causing the plastic film fragments to be conveyed to one end of the lifting device 4. Meanwhile, the mechanical action of the blades 23 causes the plastic film fragments to undergo continuous relative motion and friction in the water medium. With the help of the carrying and separation effect of the water flow, the dirt and impurities of the plastic film fragments are peeled off and removed. As the blade 23 rotates with the main shaft 22, the blade 23 drives the pusher ring 53 to rotate synchronously around the main shaft 22. The two ends of the pusher ring 53, which rotates with the blade 23, slide in the guide groove 52 of the guide block 51. Since the guide groove 52 is cam-shaped, the distance between the pusher ring 53, which slides in the guide groove 52, and the axis of the main shaft 22 will change, so that the pusher ring 53 can reciprocate on the blade 23. The reciprocating pusher ring 53 cuts and pushes the plastic film fragments wrapped on the blade 23, thereby automatically cleaning the plastic film wrapped on the blade 23 and preventing the plastic film wrapped on the blade from causing increased wear of the equipment.

[0034] During equipment operation, the pusher ring 53 rotates with the main shaft 22 and the blades 23, and the end of the pusher ring 53 slides in the guide groove 52 of the guide block 51. When the end of the pusher ring 53 passes the bottom of the guide groove 52, the end of the pusher ring 53 presses the vertical rod of the connecting rod 61 inserted in the guide groove 52, causing the connecting rod 61 to move downward as a whole. The downward-moving connecting rod 61 drives the dip plate 62 to move downward, thereby causing the dip plate 62 to push the plastic film fragments between the two blades 23 to move underwater. When the end of the blade 23 passes the inclined surface at the top of the vertical rod of the connecting rod 61, the elastic force of the compressed support spring 64 pushes the connecting rod 61 and the dip plate 62 to return to their original positions, and the plastic film fragments move upward under the action of buoyancy. After the above cycle operation, the plastic film fragments move up and down while moving towards the lifting device 4, which strengthens the friction and collision between the plastic film fragments, thereby strengthening the cleaning of the plastic film fragments and preventing the plastic film fragments from floating to the water surface and making it difficult to clean impurities.

[0035] During equipment operation, the pusher ring 53 rotates with the main shaft 22 and the blade 23, and the end of the pusher ring 53 slides in the guide groove 52 of the guide block 51. When the end of the pusher ring 53 passes the bottom of the guide groove 52, the end of the pusher ring 53 presses against the vertical rod of the connecting rod 61 inserted in the guide groove 52, causing the connecting rod 61 to move downward as a whole. The downward-moving connecting rod 61 drives the power shaft 72 to move downward. The downward-moving power shaft 72 pushes the elongated hole 731 of the disturbance plate 73, causing the disturbance plate 73 to rotate around the rotation axis 71. Due to the resistance of the water flow, part of the water flow is pushed by the disturbance plate 73, and the other part of the water flow passes through the through hole 74 and pushes the cover plate 75. Pushing open the through hole 74 and passing over the disturbance plate 73, the turbulence of the water flow in the tank 1 is enhanced, thereby improving the cleaning effect on the underwater plastic film fragments. When the end of the pusher ring 53 passes over the inclined surface at the upper end of the vertical rod of the connecting rod 61, the elastic force of the compressed support spring 64 pushes the connecting rod 61 and the power shaft 72 to return to their original position. The upward-moving power shaft 72 pushes the elongated hole 731 of the disturbance plate 73, causing the disturbance plate 73 to rotate upward around the rotating shaft 71. The upward-rotating disturbance plate 73 pushes the water flow above the disturbance plate 73, causing the disturbance plate 73 to push the water flow in the tank 1 and the underwater plastic film fragments towards the lifting device 4, thus enhancing the movement of the underwater plastic film fragments.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
