Description

Technical Field

[0001] The utility model relates to the technical field of unwinding, in particular to a non-metal flexible coil unwinding device. Background Art

[0002] With the development of the construction industry and the increasing variety of building products, people's requirements for the thermal insulation, heat insulation, sound insulation, waterproofing, etc. of building envelope structures are increasing day by day.

[0003] In the enclosure system, the single-metal-faced sandwich panel produced using non-metal flexible coils (such as TPO waterproof flexible coils) has become a new choice. On the one hand, compared with the traditional double-metal-faced sandwich panel, it can reduce the manufacturing cost and can also meet application scenarios with special performance requirements such as waterproofing and fireproofing; on the other hand, it does not require complex construction processes and special equipment, reducing the construction cost and difficulty and facilitating maintenance and replacement.

[0004] However, for the current production line equipment, it is mainly matched with the production of double-metal-faced sandwich panels. The traditional steel coil unwinder is large in size and occupies a lot of space and cannot be used in conjunction with non-metal flexible coils. Excessive tension control force of the unwinding equipment is likely to damage the material;

[0005] In addition, considering the production process, it is required that the flexible coil be compounded with rock wool before entering the double-track hot press. Since the non-metal flexible coil does not need to be processed and formed, the farther its layout position is from the double track, the more running deviation risks it will bear, affecting the product quality. Summary of the Utility Model

[0006] The utility model provides a non-metal flexible coil unwinding device, which can solve at least one of the above technical problems.

[0007] To solve the above technical problems, one or more embodiments of the utility model provide a non-metal flexible coil unwinding device, including a base, a moving frame, a driving component and an unwinding shaft. The base is used for support; the moving frame is supported by the base, and a guiding component is installed between the moving frame and the base so that the moving frame can translate relative to the base along a horizontal first direction; the driving component is used for driving the moving frame to translate and position along the first direction; the unwinding shaft is used for winding the flexible coil to be unwound. The axial direction of the unwinding shaft is parallel to the first direction. The unwinding shaft is rotationally connected to the moving frame, and one end of the unwinding shaft is connected with a magnetic powder brake, and the magnetic powder brake is fixed through the moving frame.

[0008] Further, it further includes a first rubber roller and a second rubber roller arranged side by side with their axes parallel to the first direction. The first rubber roller is rotatably connected to the moving frame. The moving frame has a second direction that is horizontal and perpendicular to the first direction. The second rubber roller is slidably connected to the moving frame and can slide along the second direction to change the distance between the first rubber roller and the second rubber roller.

[0009] Further, a brake pad is fixed to the end of the first rubber roller, and a brake is provided on one side of the first rubber roller and cooperates with the brake pad.

[0010] The beneficial effects of the above one or more technical solutions are as follows:

[0011] 1. In this solution, a flexible coiled material is unwound by an unwinding shaft. The unwinding shaft is rotatably connected to the moving frame. The moving frame can translate and be positioned relative to the base along the first direction. The guiding assembly realizes the guiding when the moving frame translates along the first direction, and the driving assembly provides power for the translation of the moving assembly. This setting enables this solution to assist in correcting the position of the flexible coiled material unwinding process during production by adjusting the relative position between the moving frame and the base, reducing the probability of the flexible coiled material being misaligned with the single-sided metal sandwich panel.

[0012] 2. One end of the unwinding shaft in this solution is coaxially fixed to the magnetic powder brake, which facilitates the use of the stepless speed regulation and on-off functions of the magnetic powder brake, and further realizes the adjustment of the tension of the flexible coiled material.

[0013] 3. There are two rubber rollers at the front end of the moving frame in this solution, which facilitates the use of the friction between the surface of the rubber rollers and the flexible coiled material to prevent the flexible coiled material from slipping and shifting during unwinding. And a brake pad is fixed to the end of the first rubber roller, and the use of the brake can achieve an emergency stop. The second rubber roller can move to change the distance between the two rubber rollers, so as to facilitate the introduction of the flexible coiled material between the first rubber roller and the second rubber roller to assist the unwinding process.
