Description

Technical Field

[0001] This utility model belongs to the field of nonwoven fabric drying technology, and relates to a surface drying device for high-strength fiber nonwoven fabric. Background Technology

[0002] The main drawbacks of existing nonwoven fabrics in air-drying tension adjustment lie in their sensitivity to changes in ambient humidity and their instability during the tension adjustment process. These drawbacks stem from the material properties of nonwoven fabrics, such as the hygroscopicity of the fibers and their shrinkage behavior during drying. Since nonwoven fabrics are typically composed of natural or synthetic fibers, these fibers undergo dimensional changes when absorbing or releasing moisture, leading to tension fluctuations. Furthermore, the initial tension setting during the production of nonwoven fabrics is often difficult to control precisely, complicating tension adjustment during drying.

[0003] Conventional solutions include using environmental control technologies, such as constant temperature and humidity systems, to maintain a stable storage and processing environment for nonwoven fabrics. The drawbacks of these methods are their high cost, requiring additional equipment investment and energy consumption. Furthermore, it is difficult to guarantee absolute environmental stability in practice, especially in large-scale production, where even minor environmental fluctuations can lead to inconsistent tension. Therefore, there is an urgent need for a high-strength fiber nonwoven fabric surface drying device to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a surface drying device for high-strength fiber nonwoven fabric, and to solve the problems mentioned in the background technology.

[0005] This utility model is achieved through the following technical solution: a surface drying device for high-strength fiber nonwoven fabric, comprising: an air circulation pipe and an external circulation pipe, wherein a set of support seats for supporting the air circulation pipe is provided on the lower side of the left and right ends respectively, and a set of heating components for heating and drying the internal air is provided on the right side of the air circulation pipe.

[0006] The heating component includes a heat insulation shell and a heating mesh. The heat insulation shell has a trapezoidal cross-section when viewed from above. An inner mounting bracket is provided on the inner left side of the heat insulation shell for installing and fixing the air guide fan. Inside the inner mounting bracket is a set of air guide fans for actively circulating the air inside the air circulation pipe. On the right side of the air guide fan is a set of limiting shells for restricting the position of the heating mesh. Both the limiting shells and the inner mounting brackets are connected and fixed to the inner side of the heat insulation shell. Inside the limiting shells are several sets of internal resistance wires for providing heating effect to the heating mesh.

[0007] In a preferred embodiment, a heating mesh for increasing the temperature of flowing air is provided inside the several sets of internal resistance wires, and the heating mesh is provided with several sets of circular air passage holes.

[0008] In a preferred embodiment, the interior of the air circulation pipe, the interior of the insulation shell, and the interior of the air passage hole are interconnected. A set of sealing shells is provided on the outside of the guide fabric component, and the interior of the insulation shell and the interior of the sealing shell are interconnected. First, the worker passes the non-woven fabric body to be dried through the partition and lays it obliquely between the tension rollers one, three sets of guide fabric rollers, and tension roller two. Then, the worker uses a control switch to control the energization of several sets of internal resistance wires, and heats the heating grid through several sets of internal resistance wires. Then, the worker uses a control switch to start the guide fan, and heats and dries the air inside the air circulation pipe before introducing it into the interior of the sealing shell, thereby drying the obliquely laid non-woven fabric body, which can effectively increase the drying area and drying time of the non-woven fabric body.

[0009] In a preferred embodiment, the guide fabric component further includes an upper adjusting column and a lower adjusting column. The upper adjusting column is provided in two sets, and each of the two sets of upper adjusting columns is provided with a connecting head at the lower end for a limited movable connection with one side end of the tensioning roller. The inner side of the two sets of upper adjusting columns is provided with a tensioning roller for adjusting the tension of the non-woven fabric body feed end.

[0010] In a preferred embodiment, the sealing shell has three sets of guide rollers inside the middle position for folding and diagonally laying the non-woven fabric in multiple directions. The three sets of guide rollers have an isosceles triangular cross-section on their front side.

[0011] In a preferred embodiment, the non-woven fabric body is guided and laid obliquely by three sets of guide rollers in a three-way folding manner. At the lower end of the guide roller on the left side, there is a tension roller two for adjusting the tension of the non-woven fabric body at the exit end. When the worker lays the non-woven fabric body obliquely through tension roller one, tension roller two and several sets of guide rollers, if the tension of the non-woven fabric body is too large or too small during the guiding process, the tension of tension roller one or tension roller two is adjusted by using two sets of upper adjustment columns and two sets of lower adjustment columns to control tension roller one or tension roller two respectively, so as to ensure the drying effect of the non-woven fabric body inside the sealed shell.

[0012] In a preferred embodiment, a set of lower adjusting columns for controlling the lifting height of the tension roller is provided at the lower ends of the front and rear sides of the tension roller. The lower adjusting columns are the same as the upper adjusting columns and are installed in a symmetrical structure. A set of partitions for guiding the non-woven fabric out is provided on the right side of the sealing shell.

[0013] In a preferred embodiment, the upper left side of the sealed shell is provided with an upper circulation head for circulating the dried air inside the sealed shell. The upper end of the upper circulation head is provided with an outer circulation pipe for guiding the circulating and recovered air. The lower left side of the outer circulation pipe is connected to the interior of the air circulation pipe.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the non-woven fabric body is penetrated through the inside of the partition and laid obliquely between the tension roller one, the three sets of guide rollers and the tension roller two. Then, the operator uses the control switch to control the energization of several sets of internal resistance wires and heats the heating net through several sets of internal resistance wires. Then, the operator uses the control switch to start the guide fan and heats and dries the air inside the air circulation pipe before introducing it into the sealed shell, thereby drying the obliquely laid non-woven fabric body. This can effectively increase the drying area and drying time of the non-woven fabric body.

[0015] The non-woven fabric body is laid obliquely using tension roller one, tension roller two, and several sets of guide rollers. When the tension of the non-woven fabric body is too high or too low during the guiding process, the tension of the obliquely laid non-woven fabric body is adjusted by using two sets of upper adjusting columns and two sets of lower adjusting columns to control tension roller one or tension roller two respectively, so as to ensure the drying effect of the non-woven fabric body inside the sealed shell.
