Technical Field

[0001] This utility model belongs to the technical field of nonwoven fabric production equipment, specifically relating to an anti-deviation guide belt conveyor device for drying flexible roll materials. Background Technology

[0002] Nonwoven fabrics possess numerous advantages, including moisture resistance, breathability, flexibility, lightweight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability, making them widely used in medical, hygiene, home furnishing, and clothing industries. Drying is a crucial step in the nonwoven fabric production process. In existing nonwoven fabric drying equipment, the fabric typically adheres directly to the inlet and outlet rollers upon entering and leaving the drying chamber. Due to uneven tension, uneven rollers, or conveying deviations, this can easily lead to wrinkles, deformation, or misalignment of the nonwoven fabric, affecting product quality and production efficiency.

[0003] Therefore, there is an urgent need for a conveying device that can effectively prevent nonwoven fabrics from wrinkling and deviating during the drying process. Utility Model Content

[0007] Further defining the above scheme, the lower part of the finely adjustable inlet tension roller bearing seat is fixed on a fine-tuning slide plate. The lower part of the fine-tuning slide plate is slidably connected to the inlet bracket via a slider and a slide rail. The slider is fixed to the lower part of the fine-tuning slide plate, and the slide rail is fixed to the inlet bracket.

[0008] Further specifying the above solution, the correction device includes an adjusting push rod and a sensor; the adjusting push rod is fixed on a push rod mounting base, the push rod mounting base is located on one side of the inlet bracket, the telescopic end of the adjusting push rod is hinged to a connecting plate, and the connecting plate is fixedly connected to a fine-tuning slide plate; two sensors are provided, respectively installed on both sides of the inlet bracket via sensor brackets, for detecting the position of both sides of the non-woven fabric drying guide net; the sensor is electrically connected to the adjusting push rod.

[0009] As a further limitation of the above scheme, the adjusting push rod is a cylinder or an electric push rod.

[0010] Further defining the above scheme, both ends of the outlet conveyor roller are fixedly supported on the outlet bracket by outlet conveyor roller bearing seats; both ends of the outlet tension roller are fixedly supported on the outlet bracket by outlet tension roller bearing seats.

[0011] Further specifying the above scheme, the non-woven fabric drying conveyor is a mesh belt structure made of polyester glass fiber material, and the outer surface of the mesh belt is coated with Teflon high-temperature resistant material.

[0012] Advantages of this utility model compared to the prior art: 1.

[0018] Please see Figure 1-4 The embodiments of this utility model are described in detail below.

[0019] like Figure 1As shown, this utility model provides an anti-deviation guide belt conveyor device for drying flexible roll materials, including a drying chamber 1, with an inlet support 2 fixed at the inlet and an outlet support 15 fixed at the outlet. An inlet conveyor roller 3 and two inlet tension rollers 5 are mounted on the inlet support 2, and an outlet conveyor roller 16 and an outlet tension roller 18 are mounted on the outlet support 15. A non-woven fabric drying guide net 20 is wound around all rollers, and the non-woven fabric 21 is adhered to the non-woven fabric drying guide net 20 and guided and conveyed through the drying chamber 1.

[0020] Preferably, the non-woven fabric drying conveyor 20 is a mesh belt structure made of polyester glass fiber material, and the outer surface of the mesh belt is coated with Teflon high-temperature resistant material.

[0021] like Figure 2 As shown, the two ends of the inlet transmission roller 3 are fixed to the inlet support 2 via inlet transmission roller bearing seats 4. Of the two inlet tension rollers 5, the inlet tension roller bearing seat 6 at one end is fixed, while the inlet tension roller bearing seat 6 at the other end is slidably connected to the inlet support 2 via a fine-tuning slide plate 7, a slider 8, and a slide rail 9, and is driven to move finely by a correction device.

[0022] Among them, such as Figure 3 , Figure 4 As shown, the lower part of the imported tension roller bearing seat 6 is fixed on the fine-tuning slide plate 7. The lower part of the fine-tuning slide plate 7 is slidably connected to the imported bracket 2 through the slider 8 and the slide rail 9. The slider 8 is fixed on the lower part of the fine-tuning slide plate 7, and the slide rail 9 is fixed on the imported bracket 2.

[0023] like Figure 2 As shown, the correction device includes an adjusting push rod 11 and a sensor 14. The adjusting push rod 11 is fixed on a push rod mounting base 10, which is located on one side of the inlet bracket 2. The telescopic end of the adjusting push rod 11 is hinged to a connecting plate 12, and the connecting plate 12 is fixedly connected to a fine-tuning slide plate 7. Two sensors 14 are provided, respectively mounted on both sides of the inlet bracket 2 via sensor brackets 13, for detecting the position of both sides of the nonwoven fabric drying guide net 20. The sensors 14 are electrically connected to the adjusting push rod 11. When the nonwoven fabric drying guide net 20 is detected to be off-center, the sensor 14 sends a signal to the adjusting push rod 11, which extends and retracts, causing the fine-tuning slide plate 7 to move, thereby adjusting the tension position and correcting the deviation of the guide net.

[0024] Preferably, the adjusting push rod 11 is a cylinder or an electric push rod.

[0025] like Figure 1 As shown, the two ends of the outlet conveyor roller 16 are fixedly supported on the outlet bracket 15 by the outlet conveyor roller bearing seats 17; the two ends of the outlet tension roller 18 are fixedly supported on the outlet bracket 15 by the outlet tension roller bearing seats 19, ensuring the smooth output of nonwoven fabric in the outlet section.

[0026] Working principle: Before entering the drying chamber from the previous process, the nonwoven fabric is bonded to the nonwoven fabric drying guide net, which is supported and tensioned by inlet transfer rollers and tension rollers. Sensors monitor the position of both sides of the guide net in real time. If a misalignment is detected, the position of one end of the inlet tension roller is finely adjusted by adjusting the push rod to restore the guide net to a centered state, thus ensuring that the nonwoven fabric passes through the drying chamber flat and without wrinkles. The outlet section has a stable structure to ensure that the nonwoven fabric is output smoothly after drying.

[0027] This invention has a reasonable structure, fast correction response, and is suitable for high-speed production nonwoven fabric drying processes, showing good application prospects.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
