Description

Technical Field

[0001] The invention belongs to the technical field of foam box foaming, in particular to a foam box production foaming device. Background Art

[0002] The foaming machine for foam box production is a device specially used for producing foam boxes. Its main function is to mix the foaming agent with air to generate uniform foam with a certain strength, which will then be used to make foam boxes.

[0003] The prior art also proposes some foaming methods. For example, a patent application with publication number CN113370452A discloses a fully automatic intermittent EPS foaming machine device, including a feeding mechanism, a foaming mechanism, a discharge fan, a steam chamber, an exhaust chamber, a drying chamber, an air supply chamber, a discharge port, a discharge baffle, an air supply fan, and a heat exchanger. The foaming machine device can effectively solve the problems of spiral conveying material accumulation and raw material breakage. In addition, the structure is compact, the footprint is small, and it is easy to transport, which effectively reduces the workload of on-site installation.

[0004] In order to ensure the foaming efficiency, the foam box foaming machine in the prior art needs to introduce hot steam into the foaming tank so that the foaming agent can contact the raw material particles. However, since the air inlet pipe is located at the top of the foaming tank, only the raw material on the top can contact the hot steam first, which results in the hot steam not being able to quickly and fully contact the raw material, thereby affecting the foaming efficiency. At the same time, after long-term use, impurities will stick to the foaming tank, thereby affecting the quality of the foam.

[0005] To this end, the present invention provides a foam box production foaming device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a foam box production and foaming device described in the present invention comprises a mixing tank; a sealing cover is installed on the top surface of the mixing tank; the top surface of the sealing cover is rotatably connected to a conduit, and the bottom surface of the conduit is sealed; the top of the conduit is connected to an external pump air component; the pump air component is used to pump hot steam into the conduit; a plurality of evenly arranged air holes are opened on the surface of the conduit; a sleeve is rotatably connected to the outside of the conduit on the bottom surface of the sealing cover; the sealing cover extends from the top of the sleeve and is driven by a servo motor; a pair of evenly arranged exhaust ports are opened on the surface of the sleeve; the plurality of exhaust ports are divided into two groups, and are respectively adapted to the two exhaust ports; two pairs of push plates are fixedly connected to the inner wall of the sleeve, and the two pairs of push plates are respectively located on both sides of the exhaust port; the surface of the conduit is fixedly connected The baffle plate; a plurality of uniformly arranged stirring plates are installed on the surface of the sleeve; the stirring plates are hollow and L-shaped; a plurality of uniformly arranged discharge ports are opened on the vertical part of the stirring plates and at one end away from the axis of the sleeve; through holes are opened on the surface of the sleeve at corresponding positions of the stirring plates, and the through holes are connected with the inside of the stirring plates; a rotating rod is rotatably connected between the inner walls of the through holes in the same row, and the top of the rotating rod extends out of the top surface of the sleeve; a blocking plate is fixedly connected to the surface of the rotating rod; a gear 1 is fixedly connected to the top surface of the rotating rod; a plurality of gears 1 are meshed and connected with a gear 2; the gear 2 is annular and rotatably connected to the top surface of the sleeve; a feeding assembly is arranged on one side of the mixing tank; an exhaust pipe is fixedly connected to the top surface of the sealing cover, and a safety valve is installed inside the exhaust pipe;During operation, when the polystyrene raw material needs to be foamed, the embodiment of the present invention can be used. First, the user needs to pour the polystyrene raw material and the foaming agent into the mixing tank. Then the user covers the sealing cover on the top surface of the mixing tank. Then the servo motor drives the sleeve to rotate clockwise and drives the push plate in the sleeve to move together until one of the push plates squeezes the baffle on the surface of the conduit, thereby driving the conduit to rotate. At this time, the exhaust port on the surface of the sleeve corresponds to the air hole on the surface of the conduit, so that the external pump air component can discharge hot steam into the polystyrene raw material and the foaming agent through the air hole on the surface of the conduit, and the sleeve will drive the stirring plate to rotate, thereby stirring the polystyrene raw material and the foaming agent. When the user needs to maintain the pressure in the mixing tank, the pump air component needs to stop introducing steam into the mixing tank. At the same time, the servo motor also needs to control the sleeve to rotate counterclockwise, and then the sleeve will drive the push plate to move until the other of the paired push plates squeezes the baffle. At this time The non-exhaust port area of ​​the sleeve will cover the pore area of ​​the conduit, thereby closing the pores and preventing the raw materials in the mixing tank from flowing into the pores, causing the pores to be blocked and affecting subsequent use. Since the conduit is inserted into the material, the hot steam can be quickly mixed into the polystyrene raw material and the foaming agent, thereby accelerating the foaming of the polystyrene raw material and improving production efficiency. After the mixing tank has been used for a long time, the user needs to clean the mixing tank. The user needs to first screw the gear 2, which drives the multiple gears 1 to rotate synchronously, and then the gear 1 drives the rotating rod to rotate again and again, and finally the rotating rod drives the blocking plate to rotate, so that the discharge port is no longer blocked by the blocking plate, and then the user needs to control the sleeve to rotate counterclockwise so that the non-exhaust port area of ​​the sleeve will cover the pore area of ​​the conduit, and the user then passes the cleaning liquid into the conduit. At this time, the cleaning liquid will enter the inside of the stirring plate from the discharge port and finally be discharged from the through hole to the outside, thereby assisting the user to clean the mixing tank. ;

In this process, the spring will be compressed, and the cover plate will also be deflected and stretched under the extrusion of the nozzle. Elastic rope, and then when the pressure of the cleaning liquid continues to increase until the pressure relief valve opens, the cleaning liquid containing pressure is sprayed out from the nozzle. When the user stops introducing cleaning liquid into the conduit, the spring and the elastic rope recover, and drive the nozzle and the cover plate to reset. Through the cooperation of the pressure relief valve and the nozzle, the nozzle can spray out pressurized cleaning liquid, thereby improving the cleaning effect of the cleaning liquid on the inner wall of the mixing tank. At the same time, the nozzle can be retracted into the through hole, and the sealing of the through hole by the cover plate can also prevent the foam from entering the nozzle during the foaming process and causing the nozzle to be blocked.

Since the end of the spiral feeding rod extends into the interior of the mixing tank, the probability of material accumulation at the end of the conveying pipe is reduced.

At the same time, the sliding rod 35 can also provide support for the end of the spiral feeding rod 28 away from the material tank 27, to prevent the end of the spiral feeding rod 28 away from the material tank 27 from directly resting on the pipe wall of the conveying pipe 26, which causes the spiral feeding rod 28 to wear the inner wall of the conveying pipe 26 when it rotates.

[0029] like Figure 1As shown, a pair of hydraulic rods 37 are installed on the side surface of the mixing tank 1; the telescopic ends of the two hydraulic rods 37 are fixedly connected with a connecting plate 38; a clearance groove 39 is opened on the surface of the connecting plate 38 at the corresponding position of the conduit 3; a connecting pipe 40 is fixedly connected to the bottom surface of the connecting plate 38 at the corresponding position of the clearance groove 39; the sealing cover 2 is installed on the bottom surface of the connecting pipe 40; during operation, when the user needs to clean the inside of the mixing tank 1, the user can start the hydraulic rod 37, and the hydraulic rod 37 drives the connecting plate 38 and the connecting pipe 40 to rise, and then the rising of the connecting pipe 40 drives the sealing cover 2 to rise, so as to lift the sealing cover 2 and move it away from the mixing tank 1. At this time, the user can clean and maintain the inside of the mixing tank 1, remove some of the foam stuck to the rotating connection between the connecting rod 21 and the roller 22, and then ensure that the roller 22 can roll normally. At the same time, the sealing cover 2 is driven to rise by the hydraulic rod 37, which can also reduce the difficulty of the user to manually lift the sealing cover 2.

[0030] like Figure 1 As shown, a support frame 41 is provided on the bottom surface of the hydraulic rod 37; the bottom of the hydraulic rod 37 is slidably connected to the support frame 41; the support frame 41 is fixedly connected to the outer surface of the mixing tank 1; during operation, when the sealing cover 2 and the conduit 3 are pulled out of the mixing tank 1, the user can slide the hydraulic rod 37 so that the sealing cover 2 is no longer located on the top of the mixing tank 1. At this time, the user controls the hydraulic rod 37 to retract, thereby lowering the sealing cover 2, thereby facilitating the user to clean the rotating rod 12, the roller 22, the conduit 3 and the sleeve 5 to extend their service life.

[0031] like Figure 1 to Figure 2 As shown, a connecting ring 42 is fixedly connected to the top surface of the conduit 3; a sealing gasket 43 is fixedly connected to the bottom surface inside the connecting ring 42; a plurality of uniformly arranged slots 44 are opened on the top surface of the connecting ring 42; a connecting ring 45 is fixedly connected to the bottom surface of the sealing cover 2; a plurality of uniformly arranged limit plates 46 are fixedly connected to the surface of the connecting ring 45; the limit plates 46 are adapted to the slots 44; the connecting pipe 40 is rotatably connected to the sealing cover 2; during operation, when the user needs to re-cover the sealing cover 2 on the top of the mixing tank 1, the user needs to rotate the sealing cover 2 on the bottom surface of the connecting pipe 40, align the limit plates 46 on the edge of the connecting ring 45 with the slots 44 on the surface of the connecting ring 42, so that the connecting ring 45 can be inserted into the connecting ring 42, and then the user rotates the sealing cover 2 again, so that the limit plates 46 on the surface of the connecting ring 45 are staggered with the slots 44 on the surface of the connecting ring 42, thereby completing the fixing of the sealing cover 2, and at the same time, the sealing gasket 43 can further ensure the sealing between the sealing cover 2 and the mixing tank 1.

[0032] During operation, when it is necessary to foam the polystyrene raw material, the embodiment of the present invention can be used. First, the user needs to pour the polystyrene raw material and the foaming agent into the mixing tank 1, and then the user covers the sealing cover 2 on the top surface of the mixing tank 1. Then the servo motor drives the sleeve 5 to rotate clockwise, and drives the push plates 7 in the sleeve 5 to move together, until one of the push plates 7 squeezes the baffle 8 on the surface of the conduit 3, thereby driving the conduit 3 to rotate. At this time, the exhaust port 6 on the surface of the sleeve 5 corresponds to the air hole 4 on the surface of the conduit 3, so that the outer The pump air assembly can discharge hot steam into the polystyrene raw material and the foaming agent through the air holes 4 on the surface of the conduit 3, and the sleeve 5 will drive the stirring plate 9 to rotate, thereby stirring the polystyrene raw material and the foaming agent. When the user needs to maintain the pressure in the mixing tank 1, the pump air assembly needs to stop introducing steam into the mixing tank 1, and the servo motor needs to control the sleeve 5 to rotate counterclockwise, and then the sleeve 5 will drive the push plate 7 to move until the other of the paired push plates 7 is squeezed to the baffle 8. At this time, the non-exhaust port of the sleeve 5 The area 6 will cover the pore 4 area of ​​the conduit 3, thereby closing the pore 4, preventing the raw materials in the mixing tank 1 from flowing into the pore 4, causing the pore 4 to be blocked and affecting subsequent use. Since the conduit 3 is inserted into the material, the hot steam can be quickly mixed into the polystyrene raw material and the foaming agent, thereby accelerating the foaming of the polystyrene raw material and thus improving the production efficiency. When the mixing tank 1 is used for a long time, the user needs to clean the mixing tank 1. To use it, the gear 2 15 needs to be screwed first, and the gear 2 15 drives the multiple gears to move. The wheel 14 rotates synchronously, and then the gear 14 drives the rotating rod 12 to rotate, and finally the rotating rod 12 drives the blocking plate 13 to rotate, so that the discharge port 10 is no longer blocked by the blocking plate 13, and then the user needs to control the sleeve 5 to rotate counterclockwise, so that the non-exhaust port 6 area of ​​the sleeve 5 will cover the air hole 4 area of ​​the conduit 3, and the user then introduces cleaning liquid into the conduit 3. At this time, the cleaning liquid will enter the inside of the stirring plate 9 from the discharge port 10, and finally be discharged to the outside through the through hole 11, thereby assisting the user to clean the mixing tank 1.

[0033] When the cleaning liquid enters the stirring plate 9 from the discharge port 10, the pressure of the cleaning liquid is not enough to push open the pressure relief valve. At this time, the nozzle 17 will be pushed out of the through hole 11 by the cleaning liquid. In this process, the spring 18 will be compressed, and the cover plate 19 will also be deflected under the squeezing of the nozzle 17 and stretch the elastic rope 20. Then, when the pressure of the cleaning liquid continues to increase, until the pressure relief valve is opened, the cleaning liquid containing pressure is sprayed out from the nozzle 17. When the user stops introducing the cleaning liquid into the conduit 3, the spring 18 and the elastic rope 20 are restored, and the nozzle 17 and the cover plate 19 are reset. Through the cooperation of the pressure relief valve and the nozzle 17, the nozzle 17 can spray out the cleaning liquid with pressure, thereby improving the cleaning effect of the cleaning liquid on the inner wall of the mixing tank 1. At the same time, the nozzle 17 can be retracted into the through hole 11, and the blocking of the through hole 11 by the cover plate 19 can also prevent the foam from entering the nozzle 17 during the foaming process, causing the nozzle 17 to be blocked.

[0034] When the sleeve 5 rotates, the sleeve 5 will also drive the connecting rod 21 to rotate, and the connecting rod 21 will drive the roller 22 to roll along the bottom surface of the mixing tank 1, and the rolling roller 22 will drive the paddle 23 on its surface to rotate with the connecting rod 21 as the axis, so that the raw materials in the mixing tank 1 are moved by the paddle 23, so that the raw materials accumulated at the bottom are brought up, thereby promoting the mixing effect of the raw materials and the hot steam, and then improving the foaming efficiency of the raw materials.

[0035] When the sleeve 5 drives the conduit 3 to rotate, the sealing plate 24 at the bottom of the sleeve 5 can prevent the raw material from entering the gap between the sleeve 5, the push plate 7 and the conduit 3, which would affect the relative rotation between the sleeve 5 and the conduit 3, and the rotating seal 25 can also ensure the sealing between the sleeve 5 and the mixing tank 1, thereby preventing the steam in the mixing tank 1 from leaking and affecting the foaming efficiency of the raw material.

[0036] When the user needs to transport materials to the mixing tank 1, the user first needs to pour the materials into the material tank 27, and then the materials will fall into the guide bucket 30 at the bottom of the material tank 27, and then the guide bucket 30 will guide the materials to the feed port 29 on the surface of the conveying pipe 26, and finally fall into the interior of the conveying pipe 26, and then the spiral feeding rod 28 rotates to feed the materials in the conveying pipe 26 into the mixing tank 1. Through the guidance of the guide bucket 30, the materials can smoothly enter the conveying pipe 26, avoiding the accumulation of materials at the edge of the material tank 27, thereby reducing the waste of materials.

[0037] Before feeding the material into the mixing tank 1, the user needs to start the telescopic tube 31 first, extend the end of the spiral feeding rod 28 into the interior of the mixing tank 1 through the telescopic tube 31, and stretch the coupling 32, and then the servo motor drives the spiral feeding rod 28 to rotate through the coupling 32 to complete the material transportation. Since the end of the spiral feeding rod 28 extends into the interior of the mixing tank 1, the probability of material accumulation at the end of the conveying pipe 26 is reduced. At the same time, the diaphragm 33 between the telescopic tube 31 and the inner wall of the conveying pipe 26 can also block the material and prevent the material from entering the gap between the surface of the telescopic tube 31 and the coupling 32, causing damage to both.

[0038] When the spiral feeding rod 28 is driven by the telescopic tube 31 to extend into the mixing tank 1, the spiral feeding rod 28 will push the sealing circular plate 36 away from the pipe opening of the conveying pipe 26, so that the spiral feeding rod 28 can normally deliver the material into the mixing tank 1. After the material delivery is completed, the telescopic tube 31 will drive the spiral feeding rod 28 to retract into the conveying pipe 26. At this time, the sealing circular plate 36 will also be buckled on the pipe opening of the conveying pipe 26 again, thereby sealing the conveying pipe 26 to prevent the material from entering the mixing tank 1. When hot steam is released, the hot steam will escape from the conveying pipe 26 to the outside, and when the spiral feeding rod 28 drives the sealing circular plate 36 to move, the sliding rod 35 will also slide in the sliding groove 34, thereby providing a limiting effect. At the same time, the sliding rod 35 can also provide support for the end of the spiral feeding rod 28 away from the material tank 27, avoiding the end of the spiral feeding rod 28 away from the material tank 27 directly resting on the wall of the conveying pipe 26, which causes the spiral feeding rod 28 to wear the inner wall of the conveying pipe 26 when it rotates.

[0039] When the user needs to clean the inside of the mixing tank 1, the user can start the hydraulic rod 37, which will drive the connecting plate 38 and the connecting pipe 40 to rise, and then the rising connecting pipe 40 will drive the sealing cover 2 to rise, thereby lifting the sealing cover 2 and moving it away from the mixing tank 1. At this time, the user can clean and maintain the inside of the mixing tank 1, remove some foam stuck to the rotating connection between the connecting rod 21 and the roller 22, thereby ensuring that the roller 22 can roll normally. At the same time, the sealing cover 2 is driven to rise by the hydraulic rod 37, which can also reduce the difficulty of the user to manually lift the sealing cover 2.

[0040] After the sealing cover 2 and the conduit 3 are pulled out of the mixing tank 1, the user can slide the hydraulic rod 37 so that the sealing cover 2 is no longer located on the top of the mixing tank 1. At this time, the user controls the hydraulic rod 37 to retract, thereby lowering the sealing cover 2, thereby making it convenient for the user to clean the rotating rod 12, the roller 22, the conduit 3 and the sleeve 5 to extend their service life.

[0041] When the user needs to put the sealing cover 2 back on the top of the mixing tank 1, the user needs to rotate the sealing cover 2 on the bottom of the connecting tube 40, align the limiting plate 46 on the edge of the connecting ring 45 with the slot 44 on the surface of the connecting ring 42, so that the connecting ring 45 can be inserted into the connecting ring 42, and then the user rotates the sealing cover 2 again so that the limiting plate 46 on the surface of the connecting ring 45 is offset from the slot 44 on the surface of the connecting ring 42, thereby completing the fixation of the sealing cover 2. At the same time, the sealing gasket 43 can further ensure the sealing between the sealing cover 2 and the mixing tank 1.
