Abstract
Description
Technical Field
[0001] This utility model relates to the field of shaping technology for mattress production, and in particular to hot air shaping equipment for producing high-elasticity and breathable coconut fiber mattresses. Background Technology
[0002] Coconut fiber mattresses are made from the outer fibers of coconut shells. Made from natural raw materials, these mattresses undergo a comprehensive technical process to achieve their advantages, including breathability, corrosion resistance, and resistance to insects, mildew, and mold. Combined with specialized hot-air shaping equipment, high-quality coconut fiber mattresses can be produced. High-elasticity, breathable coconut fiber mattresses have become increasingly popular in the bedding market in recent years due to their excellent support, breathability, and environmental friendliness. The core production process involves using hot-air shaping technology to solidify coconut fiber with natural latex or hot-melt fiber adhesives at high temperatures, forming a stable three-dimensional network structure. Traditional hot-air shaping equipment often uses a single pressure plate combined with a direct-blowing hot air system, which is insufficient to meet the shaping needs of mattresses of different thicknesses.
[0003] When the upper platen of the existing hot air shaping equipment for producing high-elasticity and breathable coconut fiber mattresses is pressed down, the coconut fiber flows randomly to both sides, resulting in loose edges and uneven thickness of the mattress. The unrestricted fiber accumulation at the edges forms irregular bulges, leading to poor thickness of the finished product. Therefore, a hot air shaping equipment for producing high-elasticity and breathable coconut fiber mattresses is proposed to solve the above problems. Utility Model Content

[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the coconut fiber to be compressed is transported into the heating box and preliminarily shaped by the flattening roller 1. The connecting block 1 is connected to the upper pressure plate through the connecting block 3. The upper pressure plate can be moved up and down for shaping by the connecting rod 1 connected to the output end of the hydraulic cylinder, which can meet the needs of different thicknesses.

[0016] 2. In this utility model, hot air is blown into pipe two through the output end of the hot air blower. The hot air is output from the air outlet of pipe two and is diverted by the diverter plate two below pipe two to divert the directly blown hot air to both sides for uniform heating. Inside pipe two, the hot air is also diverted by the diverter plate three below and then guided by the wavy shape of the heating guide plate two below, as well as by the multiple holes on the heating guide plate two. This reduces the problem of damage to coconut fiber caused by direct blowing. Pipe three works in the same way to uniformly heat the coconut fiber, thereby improving the practicality of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1-4 This utility model provides an embodiment of a hot air shaping device for producing high-elasticity and breathable coconut fiber mattresses, including a housing 1. The housing 1 serves to support and connect other components, providing a basic framework for the entire device. A heating box 2 is fixedly connected to the top of the housing 1, providing a heating space for the coconut fiber that needs to be heated. A support frame 6 is fixedly connected inside the heating box 2, used to support and fix other components. A hydraulic cylinder 14 is installed inside the housing 1. The hydraulic cylinder used in this application is an HOB series hydraulic cylinder with a rated pressure of PN5.1MPa, used to drive the upper pressure plate 12 to slide up and down. This is existing technology and will not be described in detail here. A connecting rod 13 is fixedly connected to the output end of the hydraulic cylinder 14. The hydraulic cylinder 14 is placed inside the housing 1. The connecting rod 13 is used to prevent the hydraulic cylinder 14 from being damaged under the high temperature inside the heating box 2. A shaping component is installed inside the heating box 2.
[0027] The shaping assembly includes an upper pressure plate 12, a connecting block 3 20, a connecting block 1 3, and a flattening roller 1 4. One side of the outer wall of the upper pressure plate 12 is fixedly connected to one end of a connecting rod 1 13. The upper pressure plate 12, by moving up and down, extrudes and shapes the coconut fiber. One end of the connecting block 3 20 is fixedly connected to the outer wall of the upper pressure plate 12, and one side of the outer wall of the connecting block 1 3 is fixedly connected to the other end of the connecting block 3 20.

When the connecting plate 15 is subjected to the extrusion force, it will expand and contract through the tension spring 17 on the outer wall. The tension spring 17 abuts against the inner wall of the heating box 2, which will leave space for the connecting plate 15 to move. A support frame 11 is fixedly connected to one side of the outer wall of the heating box 2. The support frame 11 is used to support and fix the hot air blower 10.

The wavy shape of the heating guide plate 27 guides the flow, and multiple holes guide the flow to reduce the problem of direct blowing damaging the coconut fiber. A pipe 9 is fixedly connected inside the pipe 28. The outer wall of the pipe 9 is fixedly connected to the inside of the box 1 and the heating box 2. A diverter plate 23 is set below the pipe 9. The flow is diverted by the diverter plate 23 and then guided by the heating guide plate 22 to evenly heat the coconut fiber. A fixing plate 21 is fixedly connected to one side of the outer wall of the diverter plate 23. The outer wall of the fixing plate 21 is fixedly connected to the inner wall of the heating box 2. A heating guide plate 22 is fixedly connected below the diverter plate 23.
[0029] Working Principle: When using the hot air shaping equipment for producing high-elasticity and breathable coconut fiber mattresses, the coconut fiber to be compressed is conveyed to the heating chamber 2 via conveyor belt 5. It undergoes initial shaping by the flattening roller 4. Connecting block 3 is connected to the upper pressure plate 12 via connecting block 3 20. The upper pressure plate 12 can be moved up and down for shaping via connecting rod 13 connected to the output end of hydraulic cylinder 14, meeting the needs of different thicknesses. Hydraulic cylinder 14 is placed inside the chamber 1, and connecting rod 13 is used to prevent damage to the hydraulic cylinder 14 under the high temperature inside the heating chamber 2. When the upper pressure plate 12 extrudes downwards, the coconut fiber will inevitably be squeezed to both sides, forming an irregular shape. The connecting plates 15 on both sides above the support frame 6 solve this problem. Flattening roller 2 19 guides the coconut fiber forward. Connecting block 2 18 moves together with connecting plate 15. When the connecting plate 15 is subjected to compressive force, it will expand and contract via tension spring 17 on the outer wall. Tension spring 17 resists the heating... The inner wall of box 2 will provide space for the connecting plate 15 to move. The connecting rod 16 will slide inside the heating box 2. The support frame 11 is used to support and fix the hot air blower 10. Hot air is blown into pipe 8 through the output end of the hot air blower 10. Hot air is output from the air outlet of pipe 8 and is divided by the diverter plate 25 below pipe 8 to distribute the directly blown hot air to both sides for uniform heating. The fixing plate 24 is used to fix the diverter plate 25. The hot air is distributed inside pipe 8 through pipe 7. The flow is also diverted through the lower diverter plate 28, and then guided by the wavy shape of the lower heating guide plate 27, as well as the multiple holes on the heating guide plate 27, to reduce the problem of direct blowing damaging the coconut fiber. The fixing plate 26 is used to fix the diverter plate 28. The same applies to the pipe 9. The flow is diverted through the lower diverter plate 23, and then guided by the heating guide plate 22 to evenly heat the coconut fiber. The fixing plate 21 is used to fix the diverter plate 23.
