Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, in particular to a hot air oven capable of uniformly heating non-woven fabrics. Background Art

[0002] Non-woven fabrics are also called non-woven fabrics, non-woven fabrics, and non-woven fabrics. They are made of oriented or randomly arranged fibers through friction, cohesion, bonding, or a combination of these methods. The connotation is "non-woven". Non-woven fabrics need to use hot air boxes in the production process. Hot air boxes can dry and heat non-woven fabrics, but the existing non-woven fabric hot air ovens still have certain use defects during use, such as:

[0003] The utility model announcement number CN218846673U discloses a hot air oven modification device for the production of non-woven fabrics for automobiles. By installing a sealing block, a nozzle and an adsorption net, the effects of heat recycling, reducing resource loss and facilitating cleaning of the adsorption net are achieved. The function of the sealing block is to provide a seal for the connection of the pull plate. The suction head collects the excess hot air discharged from the drying component and discharges it into the support box through the second pipe. The excess hot air enters the first pipe after being adsorbed by the adsorption net. The nozzle discharges the wind force to recycle its heat and reduce resource loss. Pulling the pull plate drives the magnetic block to move. The movement of the magnetic block causes the pull plate to drive the adsorption net to move. The movement of the adsorption net allows it to be quickly replaced and easily cleaned, thereby achieving the functions of heat recycling, reducing resource loss and facilitating cleaning of the adsorption net.

[0004] In the above document, the hot air oven dries the non-woven fabric through the drying component inside the shell, and the drying component is located inside the left side of the outer shell. During the drying process of the non-woven fabric, only one side of the non-woven fabric can be processed, and the drying component is fixed inside the shell and cannot be moved, resulting in a fixed distance between the non-woven fabric and the drying component, making it difficult to process the non-woven fabric in various situations.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In a specific embodiment, Figure 1-Figure 2 As shown, the uniform drying process of the non-woven fabric by the hot air box is disclosed;

[0031] A box body 1 and a feed inlet 2 opened on the right side of the box body 1;

[0032] A discharge port 3 is provided on the right side of the box body 1 and is located at the upper end of the feed port 2 , a guide roller 4 is rotatably installed inside the box body 1 , an atomization structure 5 is fixedly installed inside the box body 1 , and an observation window 6 is fixedly installed outside the box body 1 .

[0033] When using the hot air oven that can evenly heat the non-woven fabric, the hot air oven needs to be placed at the required position, and then the non-woven fabric to be processed can be heated by the hot air oven. In this process, the non-woven fabric needs to pass through the feed port 2 placed inside the hot air oven, and then the non-woven fabric is wrapped around the outside of the guide roller 4 and discharged through the discharge port 3. In this process, the atomizing structure 5 will spray mist water on both sides of the non-woven fabric, and the heating plate 9 will evenly heat both sides of the non-woven fabric, so that both sides of the non-woven fabric are heated, ensuring the heating effect of the hot air box on the non-woven fabric.

[0034] In one specific embodiment, Figure 1-Figure 4 As shown, the problem that the existing hot air box is difficult to evenly heat the non-woven fabric is solved;

[0035] A heating structure is provided inside the box 1, and the heating structure can achieve the effect of uniformly heating the non-woven fabric;

[0036] A moving groove 7 and a moving block 8 are provided inside the heating structure. The moving groove 7 is provided on the inner surface of the box body 1, and the moving block 8 is slidably installed inside the moving groove 7. A heating plate 9 is fixedly installed on the side of the moving block 8 away from the moving groove 7, and a protective net 10 is fixedly installed on the side of the heating plate 9 close to the guide roller 4.

[0037] The inner thread of the moving block 8 is provided with a threaded rod 11, and a bevel gear 12 is fixedly installed at one end of the threaded rod 11 close to the box body 1;

[0038] A rotating rod 13 is provided inside the heating structure, and a bevel gear 2 14 is fixedly installed on the outer side of the rotating rod 13 , and the bevel gear 2 14 is meshed and connected with the bevel gear 1 12 . At the same time, a turntable 15 is fixedly installed on one end of the rotating rod 13 away from the box body 1 .

[0039] When using the hot air oven that can evenly heat non-woven fabrics, the distance between the heating plate 9 and the guide roller 4 can be adjusted according to the processing requirements of the non-woven fabrics. At this time, the turntable 15 needs to be rotated, and the distance between the heating plate 9 and the guide roller 4 can be observed through the observation window 6 during the rotation of the turntable 15. The rotation of the turntable 15 will drive the rotating rod 13 to rotate inside the box body 1, and the rotation of the rotating rod 13 will cause the two sets of bevel gears 14 on its outer side to rotate, and the rotation of the bevel gear 14 will rotate through the bevel gear 12 meshing with it. At this time, the bevel gear 12 will drive the threaded rod 11 to rotate, and the rotation of the threaded rod 11 will cause the two sets of moving blocks 8 on its outer side to slide inside the moving groove 7, and the moving block 8 will drive the heating plate 9 and the protective net 10 to move during the movement, thereby changing the distance between the heating plate 9 and the non-woven fabric, so as to meet the processing requirements of the hot air box for non-woven fabrics.

[0040] Based on the above embodiments, Figure 1-Figure 2 and Figure 5-Figure 6 As shown, the problem that it is difficult to remove dust inside the existing hot air box is solved;

[0041] The upper end of the box body 1 is provided with a collecting structure, and the collecting structure can achieve the effect of collecting dust inside the box body 1;

[0042] An air outlet 16 and a fan assembly 17 are provided inside the collection structure. The air outlet 16 is fixedly installed at the upper end of the box body 1, and the fan assembly 17 is fixedly installed inside the air outlet 16.

[0043] The temporal part of the air outlet 16 is clamped with a collecting frame 18, and the upper end of the collecting frame 18 is fixedly installed with an exhaust plate 19, and the exhaust plate 19 is a hollow structure;

[0044] A fixed shaft 20 is fixedly mounted on the lower end of the collecting frame 18 , and a sealing plate 22 is rotatably mounted on the outer side of the fixed shaft 20 . A torsion spring 21 is sleeved on the outer side of the fixed shaft 20 , and the torsion spring 21 is located inside the sealing plate 22 .

[0045] When the hot air oven capable of uniformly heating non-woven fabrics is used, the fluff on the surface of the non-woven fabric will fall off inside the housing 1. At this time, the fluff inside the housing 1 needs to be cleaned, and the fan assembly 17 inside the air outlet 16 will work. During the operation of the fan assembly 17, the internal air of the housing 1 will be discharged through the air outlet 16 through the feed port 2 and the discharge port 3, and then the fluff can follow the air into the interior of the air outlet 16, and during the operation of the fan assembly 17, the sealing plate 22 will rotate on the outside of the fixed shaft 20, and the torsion spring 21 will be sealed. The sealing plate 22 is squeezed and rolled up, and the lower end of the collecting frame 18 is in an open state. At this time, the fluff will follow the air into the interior of the collecting frame 18, and the exhaust plate 19 will discharge the air outward. When the fan assembly 17 stops working, the rolled up torsion spring 21 will expand and push the sealing plate 22 to rotate. At this time, the sealing plate 22 will close with the collecting frame 18 and collect the fluff in the interior of the collecting frame 18. After that, the collecting frame 18 can be taken out from the inside of the air outlet 16 and the fluff inside it can be cleaned, thereby achieving the effect of removing dust and increasing the overall practicality.
