Description

Technical Field

[0001] This invention relates to the field of latex sheet processing technology, specifically to a drying device and process for latex sheet processing. Background Technology

[0002] Latex sheets are thin-layer materials made of natural or synthetic rubber, widely used in products such as mattresses. They are essentially a water-dispersed system of rubber microparticles, processed into sheets through special processes. They have good resilience and breathability. Depending on the process, they can be divided into dry sheets and water-washed sheets. Products with low natural latex content often have synthetic latex added to reduce costs.

[0003] Latex sheet drying is a key process in rubber product manufacturing. Its main purposes include removing moisture, ensuring product quality, and meeting process requirements. The core objective of drying is to improve product performance and stability by removing moisture. Latex sheets contain a large amount of moisture after molding. If not treated in time, it will lead to a decline in physical properties, such as substandard tensile strength and elasticity, and may even cause mold or chemical degradation. Rapid dehydration through methods such as hot air or microwave drying can stabilize the molecular structure, prevent permanent deformation, and create conditions for subsequent processing (such as vulcanization).

[0004] Currently, microwave drying is commonly used in the production of latex sheets. Microwave drying has extremely high penetration, which can improve the drying efficiency of latex materials. In existing technologies, latex sheets are generally conveyed to the drying equipment via a conveyor system. The bottom end of the latex sheet comes into contact with the conveyor, preventing the bottom surface from being fully exposed. Therefore, the drying effect on the bottom surface is not ideal, requiring flipping and secondary drying, which wastes resources and reduces drying efficiency. To address this, we propose a drying device and process for latex sheet processing. Summary of the Invention

[0005] The purpose of this invention is to provide a drying apparatus and process for processing latex sheets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drying device for latex sheet processing, comprising a machine body, with a first conveyor and a second conveyor respectively arranged on both sides of the machine body, and heat preservation curtains arranged on both sides of the machine body; further comprising: a hot air drying mechanism, the hot air drying mechanism including a plurality of air outlet pipes installed inside the machine body, the air outlet pipes having a plurality of air outlet holes, and an air inlet assembly installed at the end of the air outlet pipes, the air inlet assembly being used to deliver hot air into the air outlet pipes to dry the latex sheet, and the air inlet assembly also using air pressure to raise the air outlet pipes, lifting the latex sheet located inside the machine body to prevent the bottom of the latex sheet from being covered; a toggle mechanism, the toggle mechanism including a toggle structure and a rotating assembly, the toggle structure being installed on the air outlet pipes, and the rotating assembly being connected to the plurality of air outlet pipes. The connection includes a lever structure that lifts the latex sheet away from the air outlet pipe, creating a gap between the latex sheet and the air outlet pipe. A rotating assembly drives multiple air outlet pipes to rotate, causing the lever structure to rotate. This rotation causes the latex sheet to swing up and down. Hot air is then delivered into the air outlet pipe through the air inlet assembly to heat and dry the latex sheet. During this process, air pressure causes the air outlet pipe to rise, lifting the latex sheet and preventing the bottom of the sheet from becoming covered and difficult to dry. Furthermore, the lever structure and rotating assembly cause the air outlet pipe to rotate, which in turn causes the lever structure to rotate. The lever structure creates a gap between the latex sheet and the air outlet pipe, allowing hot air to reach the latex sheet. Its rotation further improves the drying efficiency of the latex sheet by causing it to swing up and down.

[0007] Preferably, the air inlet assembly includes a fixed frame installed inside the machine body, on which multiple connecting pipes are rotatably mounted. The multiple connecting pipes are respectively installed at both ends of multiple air outlet pipes. An elbow is fitted on the outer side of the connecting pipe, and the end of the elbow is connected to a telescopic pipe. An outer sleeve is fitted on the outer side of the telescopic pipe, and the end of the outer sleeve is connected to a thickened pipe, which facilitates the delivery of hot air into the air outlet pipe. The delivered air force increases the air pressure inside the outer sleeve, and the air pressure causes the telescopic pipe to rise, thereby facilitating the rise of the air outlet pipe.

[0008] Preferably, the telescopic tube includes a sliding tube installed inside the outer sleeve and slidably connected to the outer sleeve. The end of the sliding tube is connected to a connecting tube that is connected to the elbow. An air inlet is provided on the sliding tube, and an elastic element is also installed between the sliding tube and the outer sleeve to facilitate the air outlet tube to rise and return to its original position.

[0009] Preferably, the elastic element includes a fixing ring fixed inside the outer sleeve, a tension spring fixedly connected to the fixing ring, and a sealing ring fixedly connected to the end of the tension spring and fixedly connected to the sliding tube. The sealing ring is fitted against the inner wall of the outer sleeve to facilitate the repositioning of the air outlet duct.

[0010] Preferably, the toggle structure includes multiple rotating shafts rotatably connected to the air outlet duct. A rotating block is fixedly connected to each rotating shaft, and a toggle piece is fixedly connected to each rotating block. A connecting shaft is fixedly connected between the multiple rotating shafts. A reset component is installed at the end of the connecting shaft. A rotating component for driving the rotating shaft to rotate is installed at the end of the rotating shaft located at the end of the air outlet duct. The reset component includes a connecting piece fixedly connected to the air outlet duct. A torsion spring is fixedly connected to the connecting piece. A fixing piece fixedly connected to the end of the torsion spring is fixedly connected to the connecting shaft, so that there is a gap between the latex sheet and the air outlet duct, which facilitates hot air blowing onto the latex sheet.

[0011] Preferably, the rotating component includes incomplete gears that are fixedly connected to multiple sets of rotating shafts, and a gear ring meshes between the multiple incomplete gears. A support frame is fixedly connected to the gear ring, and a driving component is installed on the support frame to facilitate the rotation of the toggle plate.

[0012] Preferably, the driving component includes a fixed plate fixed inside the air outlet pipe. The fixed plate has several sets of through holes, and a rotating column is rotatably connected to the axis of the fixed plate. One end of the rotating column is fixedly connected to the support frame, and the other end of the rotating column is fixedly connected to a fixed block. Multiple sets of blades are fixedly connected to the fixed block to facilitate the rotation of the gear ring.

[0013] Preferably, the rotating assembly includes a first spur gear fixedly connected to multiple sets of connecting pipes, a second spur gear meshing between adjacent sets of the first spur gears, a connecting column fixedly connected to the shaft of the second spur gear and rotatably connected to the fixed frame, and a power component connected to the second spur gear to facilitate the rotation of the air outlet pipe, thereby causing multiple toggle plates to rotate.

[0014] Preferably, the power component includes a mounting bracket fixedly connected to the fixed frame, a motor fixedly connected to the mounting bracket, a drive shaft fixedly connected to the output end of the motor, a third spur gear fixedly connected to the drive shaft, a gear belt meshing with the outer side of the third spur gear, and the gear belt meshing with the second spur gear to facilitate the provision of a stable power source.

[0015] A process for a drying apparatus for processing latex sheets includes the following steps: S1: Pretreatment: First, the sheet needs to undergo pretreatment, such as mixing, curing, and foaming, to uniformly disperse the components and form a stable foam structure; S2: Heating and drying: The drying temperature needs to be strictly controlled, usually below 50℃ to avoid latex degradation. Specific parameters are adjusted according to the sheet thickness and formula. The latex sheet is dried by the machine. S3: Cooling and Shaping: After drying, the sheet is cooled and shaped to stabilize its shape and reduce internal stress; S4: Inspect the finished product: Finally, ensure uniform drying and prevent surface cracks or internal defects by means of visual inspection, thickness measurement and bonding strength test.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a drying apparatus and process for latex sheet processing. It includes a hot air drying mechanism and a rotating mechanism. The hot air drying mechanism uses an inlet component to deliver hot air into the outlet pipe to heat and dry the latex sheet. During this process, air pressure causes the outlet pipe to rise, lifting the latex sheet and preventing the bottom of the sheet from becoming covered and difficult to dry. Furthermore, during drying, a rotating mechanism and a rotating component cause the outlet pipe to rotate, which in turn rotates the rotating mechanism. This rotating mechanism creates a gap between the latex sheet and the outlet pipe, allowing hot air to reach the sheet. The rotating mechanism also moves the latex sheet up and down, further improving the drying efficiency and solving the problem of low drying efficiency in existing latex sheet technologies.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-11This invention provides a technical solution: a drying device for processing latex sheets, comprising a body 1, with a first conveyor 2 and a second conveyor 3 respectively arranged on both sides of the body 1, and heat preservation curtains 51 arranged on both sides of the body 1; further comprising: a hot air drying mechanism 4, the hot air drying mechanism 4 including multiple air outlet pipes 5 installed inside the body 1, the air outlet pipes 5 having multiple air outlet holes 6, and an air inlet assembly 7 installed at the end of the air outlet pipes 5, the air inlet assembly 7 being used to deliver hot air into the air outlet pipes 5 to dry the latex sheets, and the air inlet assembly 7 also using air pressure to raise the air outlet pipes 5, lifting the latex sheets located inside the body 1 to prevent the bottom of the latex sheets from being covered; a toggle mechanism 8, the toggle mechanism 8 including a toggle structure 9 and a rotating assembly 10, the toggle structure 9 being installed on the air outlet pipes 5, and the rotating assembly 10 being connected to the multiple air outlet pipes 5, the toggle structure 9 being used to dry the latex sheets; and a toggle mechanism 8, the toggle mechanism 8 including a toggle structure 9 and a rotating assembly 10, the toggle structure 9 being installed on the air outlet pipes 5, the rotating assembly 10 being connected to the multiple air outlet pipes 5, the toggle structure 9 being used to dry the latex sheets; and a toggle mechanism 8 including a toggle structure 9 and a rotating assembly 10. The latex sheet is lifted away from the air outlet pipe 5, creating a gap between the latex sheet and the air outlet pipe 5. The rotating component 10 drives multiple air outlet pipes 5 to rotate, causing the paddle structure 9 to rotate. The rotation of the paddle structure 9 causes the latex sheet to swing up and down. Hot air is delivered into the air outlet pipe 5 through the air inlet component 7 to heat and dry the latex sheet. During this process, the air pressure causes the air outlet pipe 5 to rise, lifting the latex sheet and preventing the bottom of the latex sheet from being covered and difficult to dry. During the drying process, the paddle structure 9 and the rotating component 10 cause the air outlet pipe 5 to rotate, which in turn causes the paddle structure 9 to rotate. The paddle structure 9 creates a gap between the latex sheet and the air outlet pipe 5, which facilitates the hot air blowing onto the latex sheet. The rotation of the paddle structure 9 also causes the latex sheet to swing up and down, further improving the drying efficiency of the latex sheet.

[0021] A process for a drying apparatus for processing latex sheets includes the following steps: S1: Pretreatment: First, the sheet needs to undergo pretreatment, such as mixing, curing, and foaming, to uniformly disperse the components and form a stable foam structure; S2: Heating and drying: The drying temperature needs to be strictly controlled, usually below 50℃ to avoid latex degradation. Specific parameters are adjusted according to the sheet thickness and formula. The latex sheet is dried by the machine. S3: Cooling and Shaping: After drying, the sheet is cooled and shaped to stabilize its shape and reduce internal stress; S4: Inspect the finished product: Finally, ensure uniform drying and prevent surface cracks or internal defects by means of visual inspection, thickness measurement and bonding strength test.

[0022] In an embodiment of the present invention, please refer to Figure 3 and Figure 4The air intake assembly 7 shown in the figure includes a fixed frame 11 installed inside the body 1. Multiple connecting pipes 12 are rotatably mounted on the fixed frame 11. The multiple connecting pipes 12 are respectively installed at both ends of multiple air outlet pipes 5. An elbow 13 is fitted on the outer side of the connecting pipe 12. The end of the elbow 13 is connected to a telescopic pipe 14. An outer sleeve 16 is fitted on the outer side of the telescopic pipe 14. The end of the outer sleeve 16 is connected to a thickened pipe 15, which facilitates the delivery of hot air into the air outlet pipe 5. The air pressure inside the outer sleeve 16 is increased by the delivered air force. The telescopic pipe 14 is raised by the air pressure, which in turn makes it easier to drive the air outlet pipe 5 to rise.

[0023] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The telescopic tube 14 shown in the figure includes a sliding tube 17 installed inside the outer tube 16 and slidably connected to the outer tube 16. The end of the sliding tube 17 is connected to a connecting tube 19 that is connected to the elbow 13. An air inlet hole 18 is provided on the sliding tube 17, and an elastic element 20 is also installed between the sliding tube 17 and the outer tube 16 to facilitate the rise and reset of the air outlet tube 5.

[0024] Furthermore, in embodiments of the present invention, please refer to... Figure 4 and Figure 5 The elastic element 20 shown in the figure includes a fixing ring 21 fixed inside the outer sleeve 16. A tension spring 22 is fixedly connected to the fixing ring 21. A sealing ring 23 fixedly connected to the end of the tension spring 22 and fixedly connected to the sliding tube 17 is fixedly connected. The sealing ring 23 is fitted to the inner wall of the outer sleeve 16 to facilitate the repositioning of the air outlet 5.

[0025] In this embodiment, the hot air source is connected to the outer tube 16. The hot air will enter the outer tube 16, increasing the air pressure inside the outer tube 16. The air pressure causes the sliding tube 17 to slide. The sliding of the sliding tube 17 causes the connecting tube 19 to drive the elbow 13 to rise. Then, the connecting tube 12 drives the air outlet 5 to rise. When the sliding tube 17 enters the thickened tube 15, the hot air will enter the sliding tube 17 through the gap between the sliding tube 17 and the thickened tube 15 and the air inlet 18. Then, the air will enter the connecting tube 19. Then, through the action of the elbow 13 and the connecting tube 12, the air will enter the air outlet 5. Finally, it will be blown out to the latex sheet through the air outlet 6. During the sliding process of the sliding tube 17, the tension spring 22 will be in a stretched state. After the hot air is lost inside the outer tube 16, the sliding tube 17 will be reset by the action of the tension spring 22, thereby resetting the connecting tube 19, elbow 13, connecting tube 12 and air outlet tube 5. The sealing ring 23 serves to seal, preventing wind from flowing away through the gap between the sliding tube 17 and the outer tube 16, thus ensuring the airtightness of the outer tube 16.

[0026] In an embodiment of the present invention, please refer to Figure 6 and Figure 7 The toggle structure 9 shown in the figure includes multiple rotating shafts 24 rotatably connected to the air outlet duct 5. A rotating block 25 is fixedly connected to the rotating shaft 24, and a toggle piece 26 is fixedly connected to the rotating block 25. A connecting shaft 27 is fixedly connected between the multiple rotating shafts 24. A reset member 29 is installed at the end of the connecting shaft 27. A rotating member 28 for driving the rotating shaft 24 to rotate is installed at the end of the rotating shaft 24 located at the end of the air outlet duct 5. The reset member 29 includes a connecting piece 30 fixedly connected to the air outlet duct 5. A torsion spring 31 is fixedly connected to the connecting piece 30. A fixing piece 32 fixedly connected to the connecting shaft 27 is fixedly connected to the end of the torsion spring 31, so that there is a gap between the latex sheet and the air outlet duct 5, which facilitates the hot air to blow onto the latex sheet.

[0027] In the embodiments of the present invention, please refer to Figure 6 and Figure 7 The rotating component 28 shown in the figure includes incomplete gears 33 that are fixedly connected to multiple sets of rotating shafts 24. Gear rings 34 mesh and drive the multiple incomplete gears 33. A support frame 35 is fixedly connected to the gear ring 34. A driving component 36 is installed on the support frame 35 to facilitate the rotation of the toggle piece 26.

[0028] Furthermore, in embodiments of the present invention, please refer to... Figure 9 and Figure 10 The driving component 36 shown in the figure includes a fixed plate 37 fixed inside the air outlet duct 5. The fixed plate 37 has several sets of through holes 38, and a rotating column 39 is rotatably connected to the axis of the fixed plate 37. One end of the rotating column 39 is fixedly connected to the support frame 35, and the other end of the rotating column 39 is fixedly connected to a fixed block 40. Multiple sets of blades 41 are fixedly connected to the fixed block 40 to facilitate the rotation of the gear ring 34.

[0029] In this embodiment, after the wind enters the air outlet duct 5, it will blow the blades 41 to rotate. The rotation of the blades 41 will drive the fixed block 40 to rotate, which in turn will drive the rotating column 39 to rotate. The rotation of the rotating column 39 will drive the support frame 35 to rotate, which will drive the gear ring 34 to rotate. The rotation of the gear ring 34 will drive the incomplete gear 33 to rotate, which will then drive the rotating shaft 24 to rotate. The connecting shaft 27 will cause all the rotating shafts 24 to rotate. Then, the rotating block 25 will drive the actuating piece 26 to rotate, causing the actuating piece 26 to unfold away from the axis of the air outlet duct 5. At this time, the latex sheet will have a gap with the air outlet duct 5 due to the action of the actuating piece 26, which will facilitate the hot air to blow onto the latex sheet.

[0030] It is worth noting that after the incomplete gear 33 loses engagement with the gear ring 34, the incomplete gear 33 will not continue to rotate. At this time, due to the presence of the torsion spring 31, the incomplete gear 33 will be in a dynamically stable state. Therefore, the actuating plate 26 will also be in an unfolded state. After the blade 41 loses the blowing force, the connecting shaft 27 will drive the rotating shaft 24 to reset due to the action of the torsion spring 31, thereby resetting the actuating plate 26. The reset of the actuating plate 26 does not affect the transmission of the latex sheet inside the machine body 1.

[0031] In an embodiment of the present invention, please refer to Figure 3 and Figure 11 The rotating assembly 10 shown in the figure includes a first spur gear 42 that is fixedly connected to multiple sets of connecting pipes 12. A second spur gear 43 meshes between two adjacent sets of first spur gears 42. A connecting column 44 that is rotatably connected to the shaft of the second spur gear 43 is fixedly connected to the shaft of the second spur gear 43. A power component 45 is connected to the second spur gear 43 to drive the air outlet pipe 5 to rotate, thereby causing multiple toggle plates 26 to rotate.

[0032] In the embodiments of the present invention, please refer to Figure 3 and Figure 11 The power component 45 shown in the figure includes a mounting bracket 46 fixedly connected to the fixed frame 11. A motor 47 is fixedly connected to the mounting bracket 46. A drive shaft 48 is fixedly connected to the output end of the motor 47. A third spur gear 49 is fixedly connected to the drive shaft 48. A gear belt 50 meshes with the outer side of the third spur gear 49. The gear belt 50 meshes with the second spur gear 43 to facilitate the provision of a stable power source.

[0033] In this embodiment, the starting motor 47 drives the drive shaft 48 to rotate, and the drive shaft 48 causes the third spur gear 49 to rotate, which in turn causes the gear belt 50 to drive the second spur gear 43 that meshes with it to rotate. The rotation of the second spur gear 43 causes the first spur gear 42 to rotate. The cooperation between the first spur gear 42 and the second spur gear 43 causes the multiple connecting pipes 12 to drive the multiple air outlet pipes 5 to rotate, thus driving the toggle plate 26 to rotate.

[0034] During implementation, the unwinding machine places the latex sheet on the first conveyor 2, which then transports the latex sheet into the machine body 1. After the latex sheet is placed on the air outlet pipe 5, the hot air source delivers hot air into the outer casing 16, increasing the air pressure inside the outer casing 16. This air pressure causes the sliding pipe 17 to slide, which in turn causes the connecting pipe 19 to lift the elbow 13. This, in turn, causes the connecting pipe 12 to lift the air outlet pipe 5. When the sliding pipe 17 enters the thickened pipe 15, the hot air will enter the sliding pipe 17 through the gap between the sliding pipe 17 and the thickened pipe 15 and the air inlet 18. Then, the air will enter the connecting pipe 19, and then, through the elbow 13 and the connecting pipe 12, the air will enter the air outlet pipe 5. Finally, the air will be blown out through the air outlet 6 onto the latex sheet. During the sliding process of the sliding tube 17, the tension spring 22 will be in a stretched state. After the hot air is lost inside the outer tube 16, the sliding tube 17 will be reset by the action of the tension spring 22, thereby resetting the connecting tube 19, elbow 13, connecting tube 12 and air outlet tube 5. Furthermore, in the above process, after the wind enters the air outlet duct 5, it will blow the blades 41 to rotate. The rotation of the blades 41 will drive the fixed block 40 to rotate, and then the fixed block 40 will drive the rotating column 39 to rotate. The rotation of the rotating column 39 will drive the support frame 35 to rotate, and the rotation of the support frame 35 will drive the gear ring 34 to rotate. The rotation of the gear ring 34 will drive the incomplete gear 33 to rotate, and then the rotating shaft 24 will rotate. Through the action of the connecting shaft 27, all the rotating shafts 24 will rotate. Then the rotating block 25 will drive the actuating piece 26 to rotate, so that the actuating piece 26 will spread away from the axis of the air outlet duct 5. At this time, the latex sheet will have a gap with the air outlet duct 5 due to the action of the actuating piece 26, which is conducive to the hot air blowing towards the latex sheet. It is worth noting that after the incomplete gear 33 loses mesh with the gear ring 34, the incomplete gear 33 will not continue to rotate. At this time, due to the presence of the torsion spring 31, the incomplete gear 33 will be in a dynamically stable state. Therefore, the actuating plate 26 will also be in an unfolded state. After the blade 41 loses the blowing force, the connecting shaft 27 will drive the rotating shaft 24 to reset due to the action of the torsion spring 31, thereby resetting the actuating plate 26. The reset of the actuating plate 26 does not affect the transmission of the latex sheet inside the machine body 1. Furthermore, during the hot air delivery process, the starting motor 47 drives the drive shaft 48 to rotate. The drive shaft 48 causes the third spur gear 49 to rotate, which in turn causes the gear belt 50 to drive the second spur gear 43, which meshes with it, to rotate. The rotation of the second spur gear 43 causes the first spur gear 42 to rotate. The cooperation between the first spur gear 42 and the second spur gear 43 causes multiple connecting pipes 12 to drive multiple air outlet pipes 5 to rotate, thus driving the agitator 26 to rotate. The rotation of the agitator 26 agitates the latex sheet, causing it to swing up and down, further improving the drying efficiency of the latex sheet.
