Description

Technical Field

[0001] This utility model relates to the field of fabric composite technology, and in particular to a pressing device for fabric composite. Background Technology

[0002] In existing technologies, composite fabrics are formed by applying adhesive between two or more layers of fabric and pressing them together. However, the current pressing process uses two pressure rollers to press the fabric together. During the pressing process, the fabric is subjected to a small force range, which can cause the adhesive to be squeezed out. In some cases, there may even be too little adhesive in certain areas, resulting in separation. This seriously affects the quality and processing stability of composite fabric products. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a pressing device for fabric lamination, which can press the glued fabric and applies pressure over a large area during the pressing process, thereby improving the stability of the fabric lamination.

[0004] This utility model discloses a pressing device for fabric lamination, including a frame, with first guide rollers rotatably arranged at both ends of the frame, a drive motor arranged on the frame at one end of the first guide roller, a first conveyor belt wound around the first guide roller, upward columns arranged at both ends of the frame, a crossbeam arranged at the top of the columns, a tension roller arranged below the upper first conveyor belt, a first bearing seat arranged at both ends of the tension roller, the two ends of the tension roller being rotatably connected to the first bearing seat, a hydraulic cylinder correspondingly arranged on the crossbeam, the telescopic end of the hydraulic cylinder extending vertically downward and fixedly connected to the first bearing seat; horizontal guide rods are arranged on the columns at both ends of the frame, a second bearing seat is fixedly arranged at the end of the guide rod, a second guide roller is arranged between the two bearing seats at the same end of the frame, a second conveyor belt is wound between the two second guide rollers, and a tension spring is arranged between the columns and the second bearing seats.

[0005] Two parallel guide rods are installed between each column and the second bearing seat, with the guide rods spaced apart. A screw hole is provided on the column between the guide rods, and a screw is installed in the screw hole. A rotating block is provided at the end of the screw near the second bearing seat, and the rotating block is rotatably connected to the screw. One end of the tension spring is fixed to the second bearing seat, and the other end of the tension spring is fixed to the rotating block. A locking nut is provided on the screw at the end away from the tension spring, and the locking nut is used to restrict the free rotation between the screw and the column.

[0006] The highest point where the first conveyor belt is stretched by the tension roller is within the diameter range corresponding to the second guide roller.

[0007] The present invention provides a pressing device for fabric composites, which uses a tensioning roller to lift the first conveyor belt upward, thereby making the first conveyor belt and the second conveyor belt fully tensioned. The coated fabric passes between the two belts, which can achieve pressing of the fabric. The large pressure area greatly improves the pressing stability of the composite fabric and enhances the quality of the composite fabric. Attached Figure Description

[0010] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0011] Example 1:

[0012] like Figure 1 , Figure 2 As shown, this utility model discloses a pressing device for fabric lamination, including a frame 1, with first guide rollers 2 rotatably arranged at both ends of the frame 1, a drive motor 17 arranged on the frame 1 at one end of the first guide roller 2, a first conveyor belt 3 wound around the first guide roller 2, upward columns 6 arranged at both ends of the frame 1, a crossbeam 7 arranged at the top of the column 6, a tension roller 4 arranged below the upper first conveyor belt 3, and first bearing seats 5 arranged at both ends of the tension roller 4. The end is rotatably connected to the first bearing seat 5. A hydraulic cylinder 8 is correspondingly provided on the crossbeam 7. The telescopic end of the hydraulic cylinder 8 extends vertically downward and is fixedly connected to the first bearing seat 5. Horizontal guide rods 12 are provided on the columns 6 at both ends of the frame 1. A second bearing seat 11 is fixedly provided at the end of the guide rod 12. A second guide roller 9 is provided between the two bearing seats at the same end of the frame 1. A second conveyor belt 10 is wound between the two second guide rollers 9. A tension spring 16 is provided between the column 6 and the second bearing seat 11.

[0013] In its natural state, the first conveyor belt 3 is loosely wound around the first guide roller 2, so the tension roller 4 is needed to tighten it. The drive motor 17 is connected to the first guide roller 2 via a transmission. When the drive motor 17 drives the first guide roller 2 to rotate, the first conveyor belt 3 moves forward on the first guide roller 2 after being tightened by the tension roller 4. Under the action of the tension spring 16, the second conveyor belt 10 between the second tension rollers 4 is in a taut state. When the first conveyor belt 3 is lifted and tightened by the tension roller 4, it partially comes into contact with the lower surface of the second conveyor belt 10, causing the second conveyor belt 10 to be lifted upward. At this time, the two second tension rollers 4 can only move closer together, overcoming the tension of the tension spring 16. During this process, the first conveyor belt 3 and the second conveyor belt 10 are kept taut, while the first conveyor belt 3 and the second conveyor belt 10 are partially and completely in contact, generating a certain amount of compressive force. In actual production, double-layered or multi-layered fabrics coated with adhesive pass between the first conveyor belt 3 and the second conveyor belt 10. While the first conveyor belt 3 is driven by the drive motor 17, the second conveyor belt 10 also runs synchronously, thus pushing the fabric forward and pressing it during the process. This results in a relatively large contact area and a long pressing time. The fabric is pressed synchronously across its width and for a considerable length, allowing for a more uniform distribution of adhesive within the fabric, a stable pressing process, and improved quality of the composite fabric.

[0014] The guide rod 12 and the column 6 are horizontally set on the column 6. That is, the column 6 is provided with a guide hole that matches the guide rod 12. The guide hole is horizontally set, so the guide rod 12 is also in a horizontal state. Therefore, the second guide roller 9 can only move horizontally under the action of the guide rod 12 and cannot move in a vertical position. In actual use, this can ensure the tightness between the second conveyor belt 10 and the first conveyor belt 3.

[0015] Two parallel guide rods 12 are provided between each column 6 and the second bearing seat 11, with the guide rods 12 spaced apart. A screw hole is provided on each column 6 between the guide rods 12, and a screw 13 is fitted into the screw hole. A rotating block 15 is provided at the end of the screw 13 closest to the second bearing seat 11, and the rotating block 15 is rotatably connected to the screw 13. One end of a tension spring 16 is fixed to the second bearing seat 11, and the other end of the tension spring 16 is fixed to the rotating block 15. A locking nut 14 is provided on the end of the screw 13 furthest from the tension spring 16, and the locking nut 14 is used to restrict the free rotation between the screw 13 and the column 6. Since different composite fabrics have different pressure requirements, the pressure between the first conveyor belt 3 and the second conveyor belt 10 needs to be adjusted. The two parallel guide rods 12 on each second bearing seat 11 make the horizontal movement of the second bearing seat 11 more stable and its horizontal support capacity stronger. Then, screw holes are provided on the columns 6 between the guide rods 12, and screw rods 13 are installed in the screw holes. The screw rods 13 are threadedly connected to the columns 6. A rotating block 15 is provided at the end of the screw rod 13. The rotating block 15 is only rotatably connected to the screw rod 13 and cannot undergo axial displacement. The two ends of a tension spring 16 are respectively connected to the second bearing 11 and the rotating block 15. By adjusting the screw rod 13, the position of the rotating block 15 is changed, thereby changing the tension state of the tension spring 16, which changes the pressure applied to the second guide roller 9 and the second conveyor belt 10. The pressure between the second conveyor belt 10 and the first conveyor belt 3 is adjusted to adapt to the pressing requirements of different composite fabrics.

[0016] The highest point of the tensioning roller 4 on the first conveyor belt 3 is within the diameter range corresponding to the second guide roller 9. In actual use, the first conveyor belt 3 must be stretched to its highest point by the tensioning roller 4 within the diameter range of the second guide roller 9 to ensure that the first conveyor belt 3 and the second conveyor belt 10 remain compressed. To allow for a larger adjustable pressure range between the first conveyor belt 3 and the second conveyor belt 10, a second guide roller 9 with a larger diameter can be used. The appropriate roller can be selected based on actual needs in practical use.
