Description

Technical Field

[0001] This invention relates to the field of unloading equipment technology, and in particular to an unloading mechanism for an EPS intermittent pre-foaming device. Background Technology

[0002] The prior art discloses a convenient unloading mechanism for a high-pressure foaming machine, with announcement number CN212400109U. It uses an air inlet main pipe and an air inlet branch pipe to release gas into the inner cavity through a jetting mechanism, so that the material inside the tank can fully contact the gas, reducing the stirring time. The discharge port is set at the bottom of the tank surface. The moving surface is pulled out, and the foamed material flows down for easy unloading. The booster pump is started so that the material remaining in the inner cavity can be squeezed out, avoiding material waste.

[0003] However, the device still has the following problems: According to existing technology, the foaming process is usually carried out by contacting the foaming material with steam. After foaming, the foaming material will have a certain degree of humidity inside. After the foamed material is discharged by the booster pump, the foamed material will soften due to excessive moisture. Also, because steam often has a certain temperature, the foamed material will often have a high temperature. After the foamed material is discharged, it may overheat and spontaneously combust. Furthermore, the moving surface extraction method will result in large pores inside the tank, which may reduce the air pressure inside the tank and thus affect the extrusion quality of the foamed material. Therefore, this application provides a discharge mechanism for an EPS intermittent pre-foaming device. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing a discharge mechanism for an EPS intermittent pre-foaming device.

The bottom of one air guide pipe extends through the functional box into the inside of the liquid storage chamber, the bottom of another air guide pipe extends through the functional box into the inside of the ventilation chamber, and the bottom of the suction pipe extends through the air distribution plate into its interior.

[0008] In the unloading mechanism of the above-mentioned EPS intermittent pre-foaming device, the stirring assembly includes an air column, a first ratchet disc is fixedly connected to the bottom of the outer surface of the air column, and an air jet rod is fixedly connected to the top of the outer surface of the air column.

[0009] In the unloading mechanism of the above-mentioned EPS intermittent pre-foaming device, the feeding assembly includes an air guide column, the inner diameter of which is equal to the outer diameter of the exhaust pipe. A second ratchet disc is fixedly connected to the top of the outer surface of the air guide column, a first gear is fixedly connected to the center of the outer surface of the air guide column, a valve stem is fixedly connected to the bottom of the outer surface of the air guide column, an exhaust disc is fixedly connected to the side of the valve stem away from the center of the air guide column, and a nozzle is fixedly connected to the bottom circumference of the exhaust disc.

[0010] In the unloading mechanism of the above-mentioned EPS intermittent pre-foaming device, the guide sealing assembly includes a second inner ratchet. A support column is fixedly connected to the top circumference of the second inner ratchet. A fixing plate is fixedly connected to the top of the support column. A first ball plate is fixedly connected to the bottom of the fixing plate on the side away from the center of the second inner ratchet. The inner surface of the second inner ratchet is in contact with the second pawl disc. A discharge groove is opened on the top circumference of the ring plate. A material passage groove is opened on the top circumference of the first inner ratchet. The inner surface of the first inner ratchet is in contact with the first pawl disc.

[0011] In the unloading mechanism of the above-mentioned EPS intermittent pre-foaming device, the drive assembly includes a drive motor, and a second gear is fixedly connected to the outer surface of the drive motor output rod, and the outer surface of the second gear meshes with the outer surface of the first gear.

[0012] In the unloading mechanism of the above-mentioned EPS intermittent pre-foaming device, the exhaust assembly includes a hollow column, a spring is fixedly connected to the top of the hollow column, a second ball plate is fixedly connected to the top of the spring, and a limiting column is fixedly connected to the center of the bottom of the second ball plate.

[0014] Compared with existing technologies, the advantages of this invention are: 1. By using the air transmission component, stirring component and material feeding component in combination, steam can be injected into the foaming material through the jet bar, so that the foaming material can foam. The nozzle can also dry and cool the foamed material and blow it downward. This ensures that the foamed material will not overheat and spontaneously combust or become too wet and softened, while also ensuring that the foamed material will not stick to the inner wall of the foaming box, thereby improving the unloading efficiency of the equipment. 2. Through the cooperation of the drive assembly and the first gear, the air guide column can rotate, which in turn allows the exhaust plate and the ventilation column to rotate. The rotation of the ventilation column allows the jet rod to stir the foaming material, thereby ensuring that the steam sprayed by the jet rod can better contact the foaming material, thus improving the foaming efficiency of the equipment. The rotation of the exhaust plate allows the nozzle to rotate and spray air onto the inner wall of the foaming box, thereby completely removing the foamed material adhering to the inside of the foaming box, thus improving the quality of the equipment's unloading. 3. By using the first and second ratchet discs in combination, the first inner ratchet can be driven to rotate during the reverse rotation of the air column, thereby controlling the position of the material passage groove opened by the first inner ratchet and thus controlling the sealing state of the ring plate. The second inner ratchet can also be driven to rotate during the reverse rotation of the air column, thereby controlling the exhaust state of the exhaust assembly, thus improving the functionality of the equipment. In summary, this invention, through the coordinated use of the gas transmission component, stirring component, material feeding component, sealing component, and driving component, enables the equipment to not only perform stirring and steam injection foaming of foaming materials, thereby improving the foaming efficiency of the equipment, but also to dry and cool the foamed material and perform downward rotational blowing. This prevents the foamed material from overheating and spontaneously combusting or becoming too wet and softened, while also guiding and blowing the foamed material adhering to the inner wall of the foaming chamber to the bottom.

[0026] Reference Figures 1-8 An unloading mechanism for an EPS intermittent pre-foaming device includes a foaming box 1. A feeding hopper 2 is fixedly connected to one side of the foaming box 1. After opening the feeding hopper 2, the operator can pour the foaming material into the interior of the foaming box 1. An air transmission component is fixedly connected to the other side of the foaming box 1. A ring plate 3 is fixedly connected to the inner wall of the foaming box 1. A first inner ratchet 4 and a stirring component are rotatably connected to the bottom of the inner cavity of the ring plate 3. A material feeding component is fixedly connected to the top of the stirring component. A guide sealing component is rotatably connected to the center of the top of the foaming box 1. A drive component is fixedly connected to one side of the top of the foaming box 1. Four exhaust components are fixedly connected to the circumference of the top of the foaming box 1. A discharge component is fixedly connected to the center of the bottom of the foaming box 1.

[0027] Reference Figure 4 The gas transmission assembly includes a functional box 5. A gas distribution plate 6 is fixedly connected to the top of the functional box 5. A vacuum pump 7 is fixedly connected to the top of the gas distribution plate 6. A vacuum pipe 8 is fixedly connected to the bottom of the vacuum pump 7. An exhaust pipe 9 is fixedly connected to the top of the vacuum pump 7. Air guide pipes 10 are fixedly connected to both the front and rear ends of the bottom of the gas distribution plate 6. An electric heater 11 is fixedly connected to the front end of the functional box 5. A filter plate 12 is fixedly connected to the rear end of the functional box 5. The functional box 5 has a liquid storage chamber 13 and a ventilation chamber 14 inside. The rear end of the electric heater 11 extends through the functional box 5 into the liquid storage chamber 13. An air guide pipe... The bottom of pipe 10 extends through the functional box 5 to the interior of the liquid storage chamber 13. The bottom of another air guide pipe 10 extends through the functional box 5 to the interior of the ventilation chamber 14. The bottom of the suction pipe 8 extends through the air distribution plate 6 to its interior. The operator can drain the liquid into the interior of the liquid storage chamber 13, then operate the electric heater 11 to heat the liquid, then open the air guide pipe 10 entering the liquid storage chamber 13 and operate the suction pump 7, so that the suction pipe 8 and the air guide pipe 10 can extract the steam generated inside the liquid storage chamber 13, and then transport the steam out through the exhaust pipe 9.

[0028] It should be noted that if the air duct 10 leading to the ventilation chamber 14 is opened and the air pump 7 is run, the air extraction pipe 8 and the air duct 10 can extract the gas filtered by the filter plate 12, and then deliver the filtered gas out through the exhaust pipe 9.

[0029] Reference Figure 2 , Figure 6 and Figure 7 The feeding assembly includes an air guide column 18, the inner diameter of which is equal to the outer diameter of the exhaust pipe 9. The exhaust pipe 9, with an inner diameter equal to that of the air guide column 18, allows the exhaust pipe 9 to transmit filtered gas and steam into the interior of the air guide column 18. A second ratchet disc 19 is fixedly connected to the top of the outer surface of the air guide column 18, a first gear 20 is fixedly connected to the center of the outer surface of the air guide column 18, a valve stem 21 is fixedly connected to the bottom of the outer surface of the air guide column 18, an exhaust disc 22 is fixedly connected to the side of the valve stem 21 away from the center of the air guide column 18, and a nozzle 23 is fixedly connected to the bottom circumference of the exhaust disc 22.

[0030] It should be noted that after the air guide column 18 receives the filtered gas, the valve stem 21 needs to be opened, so that the valve stem 21 can discharge the filtered gas into the interior of the exhaust plate 22, and then discharge the filtered gas downward through the nozzle 23. After the air guide column 18 receives the steam, it will discharge the steam downward.

[0031] The drive assembly includes a drive motor 28. A second gear 29 is fixedly connected to the outer surface of the output rod of the drive motor 28. The outer surface of the second gear 29 meshes with the outer surface of the first gear 20. The operation of the drive motor 28 can make the second gear 29 rotate, which in turn can make the first gear 20 drive the air guide column 18 to rotate.

[0032] It should be noted that when the air guide column 18 rotates in the forward direction, it will not cause the second ratchet disk 19 to drive the guide seal assembly to rotate, while when the air guide column 18 rotates in the reverse direction, it will cause the second ratchet disk 19 to drive the guide seal assembly to rotate.

[0033] Reference Figure 2 and Figure 5 The mixing assembly includes an air column 15, a first ratchet disc 16 fixedly connected to the bottom of the outer surface of the air column 15, and an air jet rod 17 fixedly connected to the top of the outer surface of the air column 15. A discharge groove 37 is provided on the top circumference of the ring plate 3, and a material passage groove 38 is provided on the top circumference of the first inner ratchet 4. The inner surface of the first inner ratchet 4 is in contact with the first ratchet disc 16. During the rotation of the air guide column 18, the air column 15 will be driven to rotate, thereby enabling the air jet rod 17 to mix the foaming material. After the air column 15 receives steam, the air jet rod 17 will transmit steam to the foaming material.

[0034] It should be noted that when the vent column 15 rotates in the forward direction, it will not cause the first pawl disc 16 to drive the first inner ratchet 4 to rotate. However, when the vent column 15 rotates in the reverse direction, it will cause the first pawl disc 16 to drive the first inner ratchet 4 to rotate.

[0035] Reference Figure 2 and Figure 3 The exhaust assembly includes a hollow column 30, a spring 31 fixedly connected to the top of the hollow column 30, a second ball plate 32 fixedly connected to the top of the spring 31, and a limiting column 33 fixedly connected to the center of the bottom of the second ball plate 32. The outer diameter of the limiting column 33 is equal to the inner diameter of the hollow column 30.

[0036] The discharge assembly includes a pump 34, with a pump pipe 35 fixedly connected to the top of the pump 34. The top of the pump pipe 35 extends through the foaming box 1 into its interior. A discharge pipe 36 is fixedly connected to one side of the pump 34. The operation of the pump 34 allows the pump pipe 35 to extract the foamed material, and then the foamed material can be discharged through the discharge pipe 36.

[0037] Reference Figure 8 The sealing assembly includes a second inner ratchet 24, with a support column 25 fixedly connected to the top circumference of the second inner ratchet 24. A fixing plate 26 is fixedly connected to the top of the support column 25. A first ball plate 27 is fixedly connected to the bottom side of the fixing plate 26 away from the center of the second inner ratchet 24. The inner surface of the second inner ratchet 24 is in contact with the second pawl disc 19. The rotation of the sealing assembly allows the first ball plate 27 to contact the second ball plate 32, thereby allowing the first ball plate 27 to exert downward pressure on the second ball plate 32. This allows the first ball plate 27 to seal the second ball plate 32, preventing the second ball plate 32 from emitting steam from the jet rod 17 during the foaming process of the foaming material.

[0038] The working principle and usage of this invention are explained in detail below: When using the equipment, the operator needs to open the feed hopper 2, pour the foaming material into the foaming box 1, and then run the drive motor 28. This causes the second gear 29 to drive the first gear 20 to rotate in the opposite direction. The first gear 20 then drives the air guide column 18, the second ratchet disc 19, the air column 15, and the first ratchet disc 16 to rotate in the opposite direction, thereby causing the second inner ratchet 24 and the first inner ratchet 4 to rotate. The rotation of the second inner ratchet 24 causes the support column 25 to rotate along with the fixing plate 26 and the first ball plate 27, thus enabling… The first ball plate 27 seals the second ball plate 32, while the rotation of the first inner ratchet 4 separates the feed chute 38 from the discharge chute 37, thus sealing the ring plate 3. Then, the electric heater 11 is activated to heat the liquid inside the storage chamber 13, generating steam. Next, the vacuum pump 7 is activated and the vent pipe 10 entering the storage chamber 13 is opened, allowing the vacuum pipe 8 to extract the steam from the storage chamber 13. The exhaust pipe 9 then transmits the steam to the vent column 18, and from there to the ventilation column 15. Steam is transmitted to the foaming material via the jet rod 17, thus initiating the foaming process. The drive motor 28 then reverses direction, causing the second gear 29 to drive the first gear 20 to rotate forward. This forward rotation of the first gear 20 causes the air guide column 18 to drive the air column 15 and the jet rod 17 to rotate, allowing the jet rod 17 to both agitate the foaming material while simultaneously releasing steam. Once the foaming material is fully foamed, the drive motor 28 is activated again, preventing the first ball plate 27 from blocking the second ball plate 32 and ensuring that the material passage trough 38 and discharge trough 37 are in a balanced state. In the same state, the foamed material can be moved downward to the suction pump 34, and then the suction pump 7 is run and the air guide pipe 10 entering the ventilation chamber 14 is opened, so that the exhaust pipe 9 can discharge the gas filtered by the ventilation chamber 14 into the air guide column 18, and then discharge the gas into the exhaust plate 22 through the valve stem 21. Finally, the gas is discharged to the foamed material through the nozzle 23, so that the foamed material can be dried and cooled. Finally, the suction pump 34 is run, so that the suction pipe 35 can extract the dried and cooled foamed material, and finally the dried and cooled foamed material is discharged to the storage tank through the discharge pipe 36.

[0039] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
