Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a honeycomb circular mesh structure. Background Technology

[0002] Nonwoven fabric is a material made by forming fibers into a web structure through mechanical, thermal bonding, or solvent methods. It is widely used in various fields such as medical and health care, household goods, and industrial protection. In the production process of nonwoven fabric, the drying process is a crucial step to ensure both quality and production efficiency. Generally, the wet material after nonwoven fabric production needs to be dried to remove moisture, thus obtaining the final dried product.

[0003] Currently, the main drying technology for nonwoven fabrics uses hot air circulation drying. Before drying, the nonwoven fabric passes over the surface of a rotary screen, where heated air is blown onto the surface of the nonwoven fabric to remove moisture. However, the drying efficiency of the rotary screen structure in existing technology is relatively low and cannot meet the demands of fast-paced production. Utility Model Content

[0004] The purpose of this application is to provide a honeycomb-type circular mesh structure to solve the problem of low drying efficiency of the existing circular mesh structure.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application provides a honeycomb circular mesh structure, which includes an inner circular mesh and an outer circular mesh, wherein:

[0007] The inner and outer circular meshes are coaxially arranged. The outer circular mesh is a hollow cylinder. The inner circular mesh is close to the inner wall of the outer circular mesh along the circumference. A drying chamber is formed between the inner and outer circular meshes. Several first through holes are evenly opened on the inner circular mesh. An external exhaust device is provided at one end of the inner circular mesh. The external exhaust device is configured to extract the gas inside the inner circular mesh.

[0008] The outer circular mesh includes several first baffles and several second baffles. The first baffles extend along a first direction and are arranged in the same circumferential direction. The second baffles are spaced apart along the first direction and have a ring-shaped structure. Each first baffle is connected to each second baffle in a cross manner, and several guide holes are formed between several adjacent first baffles and second baffles.

[0009] During drying, the fabric to be dried is placed against the outer wall of the outer circular mesh. Hot air passes through the fabric and enters the drying chamber through the guide holes. Then, it enters the inner circular mesh through the first through hole and is drawn away by the external exhaust device, thus drying the fabric.

[0010] Optionally, the first baffle is provided with a plurality of first notches spaced apart along the first direction, the openings of the first notches facing outward, and the first notches on adjacent first baffles are correspondingly arranged along the circumferential direction; the second baffle is provided with a plurality of second notches opening inward along the circumferential direction, and the second notches on adjacent second baffles are correspondingly arranged along the first direction.

[0011] The first baffle is engaged with the second baffle through the second notch on the outer side of the circumference, and the second baffle is engaged with the first baffle through the first notch on the inner side of the circumference.

[0012] Optionally, a number of first notches are evenly spaced along a first direction on the corresponding first baffle, and a number of second notches are evenly distributed along the circumferential direction on the corresponding second notches.

[0013] Optionally, the first notch and the second notch have the same specifications, the first baffle and the second baffle have the same width extending in the circumferential direction, the width of the first baffle is twice the depth of the first notch, and the width of the second baffle is twice the depth of the second notch.

[0014] Optionally, a first inclined surface and a second inclined surface are provided at the opening of the first notch and the opening of the second notch, and both the first inclined surface and the second inclined surface are inclined away from the opening.

[0015] Optionally, the inner circular mesh is provided with several air regulating plates and at least one fixing component. The several air regulating plates are evenly spaced and attached to the inner wall of the inner circular mesh along the first direction. Several second through holes are opened on the air regulating plates. The several second through holes correspond to the first through holes on the corresponding area of ​​the inner circular mesh along the circumferential direction.

[0016] The fastener is detachably fixed to the inner wall of the inner circular mesh along the first direction. The fastener extends along the first direction, and the air regulating plate is located between the fastener and the inner circular mesh. After the fastener is disassembled, the air regulating plate can rotate relative to the inner circular mesh along the axis of the inner circular mesh to change the relative position between the corresponding first through hole and the second through hole, so that interference is formed between the air regulating plate and the first through hole, thereby adjusting the efficiency of hot air entering the inner circular mesh from the drying chamber.

[0017] Optionally, a baffle plate is provided between the first end of the inner circular mesh along the circumferential direction and the second end of the inner circular mesh along the circumferential direction. The baffle plate is close to the outer circular mesh and is configured to block the airflow between the corresponding area of ​​the baffle plate in the drying chamber and the interior of the inner circular mesh.

[0018] Optionally, the wind deflector can be configured as an arc-shaped structure.

[0019] Compared with the prior art, the honeycomb circular mesh structure proposed in this application has the following advantages:

[0020] 1) By setting a drying chamber between the inner and outer circular mesh, the hot air entering the drying chamber comes into secondary contact with the fabric, increasing the contact time between the hot air and the fabric to improve drying efficiency; the cooperation of the first and second baffles forms several guide holes, which provide stable support for the fabric to be dried while increasing the total opening area of ​​the channel for hot air to enter the drying chamber, ensuring that the hot air quickly enters the drying chamber after passing through the fabric, effectively improving drying efficiency.

[0021] 2) By using the first notch on the first baffle and the second notch on the second baffle, a simple, easy-to-operate and non-loose snap-fit ​​method is provided for the first baffle and the second baffle, ensuring the stability of the outer circular mesh structure and avoiding the drying effect of the fabric due to structural loosening during the drying process.

[0022] 3) Through the cooperation of fasteners, air regulating plates and inner circular mesh, the hot airflow can be adjusted according to the demand, avoiding uneven local temperature and improving the overall drying efficiency and adaptability. Attached Figure Description

[0030] Please see Figures 1 to 5 As shown in the embodiment of this application, a honeycomb circular mesh structure is provided, which includes an inner circular mesh 10 and an outer circular mesh 20, wherein: the inner circular mesh 10 and the outer circular mesh 20 are coaxially arranged, the outer circular mesh 20 is a hollow cylinder, the inner circular mesh 10 is close to the inner wall of the outer circular mesh 20 along the circumferential direction, a drying chamber 11 is formed between the inner circular mesh 10 and the outer circular mesh 20, a plurality of first through holes 12 are evenly opened on the inner circular mesh 10, and an external exhaust device is provided at one end of the inner circular mesh 10, the external exhaust device being configured to extract the gas inside the inner circular mesh 10; the outer circular mesh 20 includes a plurality of first baffles 21 and a plurality of second baffles 22, the first baffles 21 are along a first direction ( Figure 1 Extending in the direction of X, several first baffles 21 are arranged in the same circumferential direction, and second baffles 22 are arranged at intervals along the first direction. The second baffles 22 have a circular structure. Each first baffle 21 and each second baffle 22 are cross-connected. Several guide holes 23 are formed between several adjacent first baffles 21 and second baffles 22. During drying, the fabric to be dried is attached to the outer wall of the outer circular mesh 20. Hot air passes through the fabric and enters the drying chamber 11 through the guide holes 23. Then it enters the inner circular mesh 10 through the first through hole 12 and is then drawn away by the external exhaust device to achieve the drying of the fabric.

[0031] A drying chamber 11 is set between the inner circular mesh 10 and the outer circular mesh 20, allowing the hot air entering the drying chamber 11 to come into secondary contact with the fabric, increasing the contact time between the hot air and the fabric, thereby improving drying efficiency. The cooperation of the first baffle 21 and the second baffle 22 forms a number of guide holes 23, which provide stable support for the fabric to be dried, while increasing the total opening area of ​​the channel for hot air to enter the drying chamber 11, ensuring that the hot air quickly enters the drying chamber 11 after passing through the fabric, effectively improving drying efficiency.

[0032] In one embodiment, the first baffle 21 is provided with a plurality of first notches 210 spaced apart along a first direction, the first notches 210 opening outward, and the first notches 210 on adjacent first baffles 21 are correspondingly arranged along the circumferential direction. The second baffle 22 is provided with a plurality of second notches 220 opening inward along the circumferential direction, and the second notches 220 on adjacent second baffles 22 are correspondingly arranged along the first direction. The outer side of the first baffle 21 along the circumferential direction is engaged with the second baffle 22 through the second notches 220, and the second baffle 22 along the circumferential direction is engaged with the first baffle 21 through the first notches 210.

[0033] The cooperation of the first notch 210 on the first baffle 21 and the second notch 220 on the second baffle 22 provides a simple, easy-to-operate, and non-loose snap-fit ​​method for the first baffle 21 and the second baffle 22, ensuring the stability of the outer circular mesh 20 structure and avoiding the drying effect of the fabric due to structural loosening during the drying process.

[0034] In one embodiment, a plurality of first notches 210 are evenly spaced along a first direction on the corresponding first baffle 21, and a plurality of second notches 220 are evenly distributed along the circumferential direction on the corresponding second notches 220.

[0035] By uniformly setting the first notch 210 and the second notch 220, the uniformity of the distribution of the guide holes 23 is ensured, avoiding localized poor hot air flow or excessive concentration, thereby improving the drying efficiency and quality.

[0036] In one embodiment, the first notch 210 and the second notch 220 have the same specifications, the first baffle 21 and the second baffle 22 extend with the same width in the circumferential direction, the width of the first baffle 21 is twice the depth of the first notch 210, and the width of the second baffle 22 is twice the depth of the second notch 220.

[0037] By standardizing the specifications of the first notch 210 and the second notch 220, as well as the widths of the first baffle 21 and the second baffle 22, and setting the notch to be half the width of the baffle, the first baffle 21 and the second baffle 22 are fully engaged, which improves the structural strength of the outer circular mesh 20 while ensuring the flatness of the inner and outer walls of the outer circular mesh 20. This helps to provide uniform support for the fabric and further ensures the uniformity of fabric drying.

[0038] In one embodiment, a first inclined surface 230 and a second inclined surface 231 are provided at the opening of the first notch 210 and the opening of the second notch 220, respectively, and both the first inclined surface 230 and the second inclined surface 231 are inclined away from the opening.

[0039] Specifically, the first inclined plane 230 and the second inclined plane 231 have the same inclination angle but opposite directions.

[0040] The cooperation between the first inclined surface 230 and the second inclined surface 231 increases the opening of the notch, facilitates quick snap-fit ​​between the baffles, improves the installation efficiency of the circular mesh, and is conducive to high-efficiency production requirements.

[0041] In one embodiment, the inner circular mesh 10 is provided with a plurality of air regulating plates 14 and at least one fixing member 13. The plurality of air regulating plates 14 are evenly spaced along the first direction and are attached to the inner wall of the inner circular mesh 10. The air regulating plates 14 are provided with a plurality of second through holes 140. The plurality of second through holes 140 correspond to the first through holes 12 in the corresponding area of ​​the inner circular mesh 10 along the circumferential direction.

[0042] The fixing member 13 is detachably fixed to the inner wall of the inner circular mesh 10 along the first direction. The fixing member 13 extends along the first direction. The air regulating plate 14 is located between the fixing member 13 and the inner circular mesh 10. After the fixing member 13 is disassembled, the air regulating plate 14 can rotate relative to the inner circular mesh 10 along the axis of the inner circular mesh 10 to change the relative position between the corresponding first through hole 12 and second through hole 140, so that the air regulating plate 14 and the first through hole 12 form interference, thereby adjusting the efficiency of hot air entering the inner circular mesh 10 from the drying chamber 11.

[0043] Specifically, the first through hole 12 and the second through hole 140 have the same specifications.

[0044] Specifically, the fastener 13 has a first through hole 130 and a second through hole 131, the air regulating plate 14 has a third through hole, and the inner circular mesh 10 has a first threaded hole and a second threaded hole. The first through hole corresponds to the first threaded hole. The bolt passes through the first through hole and is screwed into the first threaded hole to fix the fastener 13 and the inner circular mesh 10. The second threaded hole, the second through hole 131 and the third through hole correspond to each other. The bolt passes through the second through hole and the third through hole in sequence and is screwed into the second threaded hole to fix the fastener 13, the air regulating plate 14 and the inner circular mesh 10.

[0045] Specifically, fastener 13 is set as a fixing plate.

[0046] The combination of the fixing component 13, the air regulating plate 14 and the inner circular mesh 10 allows the hot airflow to adjust its flow rate as needed, avoiding uneven local temperature and improving overall drying efficiency and adaptability.

[0047] In one embodiment, a baffle plate 15 is provided between the first end of the inner circular mesh 10 along the circumferential direction and the second end of the inner circular mesh 10 along the circumferential direction. The baffle plate 15 is close to the outer circular mesh 20. The baffle plate 15 is configured to block the gas flow between the corresponding area of ​​the baffle plate 15 in the drying chamber 11 and the interior of the inner circular mesh 10.

[0048] Specifically, the outer circular mesh 20 and the inner circular mesh 10 are mounted on the same rotating shaft. The outer circular mesh 20 is fixedly connected to the rotating shaft, and the inner circular mesh 10 is fixedly connected to the bearing. The bearing is mounted on the rotating shaft so that the inner circular mesh 10 rotates relative to the rotating shaft. An external drive device drives the outer circular mesh 20 to rotate to transport the fabric, while the inner circular mesh 10 remains stationary.

[0049] By setting a baffle plate 15 on the inner circular mesh 10, the air flow between the area corresponding to the baffle plate in the drying chamber 11 along the first direction and the inside of the inner circular mesh 10 is prevented. This prevents the fabric from being adsorbed on the area corresponding to the baffle plate 15 in the first direction on the outer circular mesh 20. This facilitates the removal of the dried fabric from the outer circular mesh 20, making subsequent fabric drying easier and improving drying efficiency.

[0050] In one embodiment, the wind deflector 15 is configured as an arc-shaped structure.

[0051] By using an arc-shaped baffle plate 15, the hot air is distributed more smoothly, which helps the hot air to quickly reach the guide hole 23 near the baffle plate 15, thereby improving the utilization rate of hot air and further optimizing the drying effect.

[0052] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
